Caution Regarding Forward-Looking Statements
Any statements in this Form 10-Q that are not historical facts are specifically identified as forward-looking statements. These statements are based upon our estimates and anticipation of future events and are subject to significant risks, assumptions and uncertainties that could cause actual results to vary materially from the expected results described in the forward-looking statements. Forward-looking statements are identified by words such as, but not limited to, "anticipate," "believe," "estimate," "expect," "hope," "hopeful," "intend," "likely," "may," "optimistic," "possible," "potential," "preliminary," "project," "should," "will" and other analogous expressions. There are numerous factors that could cause our actual results to differ materially from those in the forward-looking statements. Thus, sentences and phrases that we use to convey our view of future events and trends are expressly designated as forward-looking statements as are sections of this Form 10-Q that are identified as giving our outlook on future business.
Forward-looking statements relating to our business include among other things: statements concerning future liquidity and capital requirements, investment valuation and performance, return on equity, financial ratios, net income, premiums, losses and loss reserve, premium rates and retention of current business, competition and market conditions, the expansion of product lines, the development or acquisition of business in new geographical areas, the availability of acceptable reinsurance, actions by regulators and rating agencies, court actions, legislative actions, payment or performance of obligations under indebtedness, payment of dividends and other matters.
These forward-looking statements are subject to significant risks, assumptions and uncertainties, including, among other things, the following factors that could affect the actual outcome of future events:
Ÿ
changes in general economic conditions, including the impact of inflation or deflation and unemployment;
Ÿ
our ability to maintain our dividend payments;
Ÿ
regulatory, legislative and judicial actions or decisions that could affect our business plans or operations;
Ÿ
the enactment or repeal of tort reforms;
Ÿ
formation or dissolution of state-sponsored insurance entities providing coverages now offered by ProAssurance which could remove or add sizable numbers of insureds from or to the private insurance market;
Ÿ
changes in the interest and tax rate environment;
Ÿ
resolution of uncertain tax matters and changes in tax laws, including the impact of the TCJA;
Ÿ
changes in laws or government regulations regarding financial markets or market activity that may affect our business;
Ÿ
changes in the ability of the U.S. government to meet its obligations that may affect the U.S. economy and our business;
Ÿ
performance of financial markets affecting the fair value of our investments or making it difficult to determine the value of our investments;
Ÿ
changes in requirements or accounting policies and practices that may be adopted by our regulatory agencies, the FASB, the SEC, the PCAOB or the NYSE that may affect our business;
Ÿ
changes in laws or government regulations affecting the financial services industry, the property and casualty insurance industry or particular insurance lines underwritten by our subsidiaries;
Ÿ
the effect on our insureds, particularly the insurance needs of our insureds, and our loss costs, of changes in the healthcare delivery system and/or changes in the U.S. political climate that may affect healthcare policy or our business;
Ÿ
consolidation of our insureds into or under larger entities which may be insured by competitors, or may not have a risk profile that meets our underwriting criteria or which may not use external providers for insuring or otherwise managing substantial portions of their liability risk;
Ÿ
uncertainties inherent in the estimate of our loss and loss adjustment expense reserve and reinsurance recoverable;
Ÿ
changes in the availability, cost, quality or collectability of insurance/reinsurance;
Ÿ
the results of litigation, including pre- or post-trial motions, trials and/or appeals we undertake;
Ÿ
effects on our claims costs from mass tort litigation that are different from that anticipated by us;
Ÿ
allegations of bad faith which may arise from our handling of any particular claim, including failure to settle;
Ÿ
loss or consolidation of independent agents, agencies, brokers or brokerage firms;
Ÿ
changes in our organization, compensation and benefit plans;
Ÿ
changes in the business or competitive environment may limit the effectiveness of our business strategy and impact our revenues;

Table of Contents

Ÿ
our ability to retain and recruit senior management;
Ÿ
the availability, integrity and security of our technology infrastructure or that of our third-party providers of technology infrastructure, including any susceptibility to cyber-attacks which might result in a loss of information or operating capability;
Ÿ
the impact of a catastrophic event, as it relates to both our operations and our insured risks;
Ÿ
the impact of acts of terrorism and acts of war;
Ÿ
the effects of terrorism-related insurance legislation and laws;
Ÿ
guaranty funds and other state assessments;
Ÿ
our ability to achieve continued growth through expansion into new markets or through acquisitions or business combinations;
Ÿ
changes to the ratings assigned by rating agencies to our insurance subsidiaries, individually or as a group;
Ÿ
provisions in our charter documents, Delaware law and state insurance laws may impede attempts to replace or remove management or may impede a takeover;
Ÿ
state insurance restrictions may prohibit assets held by our insurance subsidiaries, including cash and investment securities, from being used for general corporate purposes;
Ÿ
taxing authorities can take exception to our tax positions and cause us to incur significant amounts of legal and accounting costs and, if our defense is not successful, additional tax costs, including interest and penalties; and
Ÿ
expected benefits from completed and proposed acquisitions may not be achieved or may be delayed longer than expected due to business disruption; loss of customers, employees or key agents; increased operating costs or inability to achieve cost savings; and assumption of greater than expected liabilities, among other reasons.
Additional risks, assumptions and uncertainties that could arise from our membership in the Lloyd's market and our participation in Lloyd's Syndicates include, but are not limited to, the following:
Ÿ
members of Lloyd's are subject to levies by the Council of Lloyd's based on a percentage of the member's underwriting capacity, currently a maximum of 3%, but can be increased by Lloyd's;
Ÿ
Syndicate operating results can be affected by decisions made by the Council of Lloyd's which the management of Syndicate 1729 and Syndicate 6131 have little ability to control, such as a decision to not approve the business plan of Syndicate 1729 or Syndicate 6131, or a decision to increase the capital required to continue operations, and by our obligation to pay levies to Lloyd's;
Ÿ
Lloyd's insurance and reinsurance relationships and distribution channels could be disrupted or Lloyd's trading licenses could be revoked making it more difficult for a Lloyd's Syndicate to distribute and market its products;
Ÿ
rating agencies could downgrade their ratings of Lloyd's as a whole; and
Ÿ
Syndicate 1729 and Syndicate 6131 operations are dependent on a small, specialized management team and the loss of their services could adversely affect the Syndicate’s business. The inability to identify, hire and retain other highly qualified personnel in the future, could adversely affect the quality and profitability of Syndicate 1729’s or Syndicate 6131's business.
Our results may differ materially from those we expect and discuss in any forward-looking statements. The principal risk factors that may cause these differences are described in "Item 1A, Risk Factors" in our Form 10-K and other documents we file with the SEC, such as our current reports on Form 8-K and our regular reports on Form 10-Q.
We caution readers not to place undue reliance on any such forward-looking statements, which are based upon conditions existing only as of the date made, and advise readers that these factors could affect our financial performance and could cause actual results for future periods to differ materially from any opinions or statements expressed with respect to future periods in any current statements. Except as required by law or regulations, we do not undertake and specifically decline any obligation to publicly release the result of any revisions that may be made to any forward-looking statements to reflect events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events.

ProAssurance Corporation and Subsidiaries
Notes to Condensed Consolidated Financial Statements (Unaudited)
September 30, 2018


1. Basis of Presentation
The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of ProAssurance Corporation and its consolidated subsidiaries (ProAssurance, PRA or the Company). The financial statements have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation, consisting of normal recurring adjustments, have been included. ProAssurance’s results for the nine months ended September 30, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. The accompanying Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Notes contained in ProAssurance’s December 31, 2017 report on Form 10-K. In connection with its preparation of the Condensed Consolidated Financial Statements, ProAssurance evaluated events that occurred subsequent to September 30, 2018 for recognition or disclosure in its financial statements and notes to financial statements.
Beginning in the third quarter of 2018, ProAssurance operates in five reportable segments as follows: Specialty P&C, Workers' Compensation Insurance, Segregated Portfolio Cell Reinsurance, Lloyd's Syndicates and Corporate. For more information on the Company's segment reporting, including the nature of products and services provided and financial information by segment, refer to Note 13.
Reclassifications
As a result of the third quarter 2018 segment reorganization, prior period segment information in Note 13 has been recast to conform to the Company's current segment reporting (see Note 13 for further information).
Certain other insignificant prior period amounts have been reclassified to conform to the current period presentation.
Accounting Policies
Except as added below, the significant accounting policies followed by ProAssurance in making estimates that materially affect financial reporting are summarized in Note 1 of the Notes to Consolidated Financial Statements in ProAssurance’s December 31, 2017 report on Form 10-K.
Retroactive Insurance Contracts
In certain instances, ProAssurance’s insurance contracts cover losses both on a prospective basis and retroactive basis and, accordingly, ProAssurance bifurcates the prospective and retroactive provisions of these contracts and accounts for each component separately, where practicable. The prospective provisions of a contract are accounted for consistently with the Company’s other insurance contracts as discussed in Note 1 of the Notes to Consolidated Financial Statements in ProAssurance’s December 31, 2017 report on Form 10-K.
Under the retroactive provisions of a contract, all premiums received and losses assumed are recognized immediately in earnings at the inception of the contract as all of the underlying loss events occurred in the past. If the estimated losses assumed differ from the premium received related to the retroactive provision of a contract, the resulting difference is deferred and recognized over the estimated claim payment period with the periodic amortization reflected in earnings as a component of net losses and loss adjustment expenses. Deferred gains are included as a component of the reserve for losses and loss adjustment expenses and deferred losses are included as a component of other assets on the Condensed Consolidated Balance Sheet. Subsequent changes to the estimated timing or amount of future loss payments in relation to the losses assumed under retroactive provisions also produce changes in deferred balances. Changes in such estimates are applied retrospectively and the resulting changes in deferred balances, together with periodic amortization, are included in earnings in the period of change.

SPC dividends payable are the cumulative undistributed earnings contractually payable to the external cell owners of the SPCs operated by Eastern Re and Inova Re, ProAssurance's Cayman Islands reinsurance subsidiaries.
Unpaid dividends represent common stock dividends declared by ProAssurance's Board that had not yet been paid as of September 30, 2018. Unpaid dividends at December 31, 2017 reflected a special dividend declared in the fourth quarter of 2017 that was paid in January 2018.
Accounting Changes Adopted
Restricted Cash (ASU 2016-18)
Effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years, the FASB issued guidance related to the classification of restricted cash presented in the statement of cash flows with the objective of reducing diversity in practice. Under the new guidance, entities are required to include restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts as presented on the statement of cash flows. ProAssurance adopted the guidance as of January 1, 2018. Adoption of the guidance had no material effect on ProAssurance’s results of operations, financial position or cash flows.
Intra-Entity Transfers of Assets Other than Inventory (ASU 2016-16)
Effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years, the FASB issued guidance which reduces the complexity in accounting standards related to the income tax consequences of intra-entity transfers of assets other than inventory between tax-paying components. A tax-paying component is an individual entity or group of entities that is consolidated for tax purposes. Under the new guidance, entities are required to recognize income tax consequences of an intra-entity transfer of assets other than inventory when the transfer occurs instead of delaying recognition until the asset has been sold to an outside party. ProAssurance adopted the guidance as of January 1, 2018. Adoption of the guidance had no material effect on ProAssurance’s results of operations, financial position or cash flows.
Classification of Certain Cash Receipts and Cash Payments (ASU 2016-15)
Effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years, the FASB issued guidance related to the classification of certain cash receipts and cash payments presented in the statement of cash flows with the objective of reducing diversity in practice. ProAssurance adopted the guidance as of January 1, 2018 and elected to use the cumulative earnings approach for presenting distributions from equity method investees. Adoption of the guidance had no material effect on ProAssurance’s results of operations or financial position; however, ProAssurance reclassified approximately $20.2 million in distributions from unconsolidated subsidiaries from investing activities to operating activities in the Condensed Consolidated Statement of Cash Flows for the nine months ended September 30, 2017.
Revenue from Contracts with Customers (ASU 2014-09)
Effective for fiscal years beginning after December 15, 2017 the FASB issued guidance related to revenue from contracts with customers. The core principle of the new guidance is that revenue is recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ProAssurance adopted the guidance as of January 1, 2018 under the modified retrospective method. Adoption of the guidance had no material effect on ProAssurance’s results of operations, financial position or cash flows.
Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01)
Effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years, the FASB issued guidance that requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. The new guidance also specifies that an entity use the exit price notion when measuring the fair value of financial instruments for disclosure purposes and present financial assets and liabilities by measurement category and form of financial asset. Other

13

Table of Contents

Notes to Condensed Consolidated Financial Statements (Unaudited)

provisions of the new guidance include: revised disclosure requirements related to the presentation in comprehensive income of changes in the fair value of liabilities; elimination, for public companies, of disclosure requirements relative to the methods and significant assumptions underlying fair values disclosed for financial instruments measured at amortized cost; and simplified impairment assessments for equity investments without readily determinable fair values. ProAssurance adopted the guidance as of January 1, 2018 using a modified retrospective application and recorded a cumulative-effect after-tax adjustment of approximately $8.3 million to beginning retained earnings in the Condensed Consolidated Statement of Changes in Capital for the nine months ended September 30, 2018. LPs/LLCs previously reported using the cost method are now reported at fair value with increases in fair value of approximately $5.2 million and $11.1 million recognized as a component of equity in earnings (loss) of unconsolidated subsidiaries on the Condensed Consolidated Statements of Income and Comprehensive Income for the three and nine months ended September 30, 2018, respectively.
Modification Accounting for Employee Share-Based Payment Awards (ASU 2017-09)
Effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years, the FASB issued guidance which reduces the complexity in accounting standards when there is a change in the terms or conditions of a share-based payment award. The new guidance clarifies that an entity should apply the modification accounting guidance if the value, vesting conditions or classification of the award changes. ProAssurance adopted the guidance as of January 1, 2018. Adoption of the guidance had no material effect on ProAssurance’s results of operations, financial position or cash flows.
Reclassification of Certain Tax Effects from AOCI (ASU 2018-02)
Effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, with early adoption permitted, the FASB issued guidance which permits a reclassification from AOCI to retained earnings for stranded tax effects resulting from the newly enacted federal corporate tax rate from the TCJA. The amount of the reclassification from AOCI to retained earnings will be the difference between the historical corporate tax rate and the newly enacted 21% corporate tax rate on deferred tax items originally established through OCI and not net income. The guidance allows entities to adopt in any interim or annual period for which financial statements have not yet been issued and apply the guidance either (1) in the period of adoption or (2) retrospectively to each period in which the effect of the change in the tax rate is recognized. ProAssurance adopted this guidance as of January 1, 2018 and elected to apply this guidance in the period of adoption using the specific identification method. Using a modified retrospective application, ProAssurance recorded a cumulative-effect adjustment which increased beginning AOCI by approximately $3.4 million and decreased beginning retained earnings by the same amount in the Condensed Consolidated Statement of Changes in Capital for the nine months ended September 30, 2018. Adoption of this guidance had no material effect on ProAssurance's financial position, results of operations or cash flows.
Technical Corrections and Improvements to Financial Instruments - Overall (ASU 2018-03)
Effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years beginning after June 15, 2018, the FASB amended the new standard on recognizing and measuring financial assets and financial liabilities to clarify certain aspects of the guidance. Under the amended guidance, an entity that uses the measurement alternative for equity investments without readily determinable fair values can change its measurement approach to a fair value method through an irrevocable election that would apply to that security and all identical or similar investments of the same issuer. Also, entities are required to use the prospective transition approach only for equity investments they elect to measure using the new measurement alternative. Additionally, the guidance clarifies how to apply the measurement alternative and presentation requirements for financial liabilities measured under the fair value option. ProAssurance adopted the guidance as of July 1, 2018 and adoption had no material effect on ProAssurance's financial position, results of operations or cash flows as ProAssurance does not have any equity investments without readily determinable fair values or financial liabilities measured under the fair value option.
Accounting Changes Not Yet Adopted
Leases (ASU 2016-02)
Effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, the FASB issued guidance that requires a lessee to recognize for all leases (with the exception of short-term leases) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis, and a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. ProAssurance plans to adopt the guidance beginning January 1, 2019 using a modified retrospective application and plans to elect the transition option provided that allows companies to continue to apply legacy GAAP in comparative periods. As of September 30, 2018, ProAssurance is currently in the process of evaluating all of its leases. As the majority of ProAssurance's leases are real estate operating leases and are not considered to be material, adoption of the guidance is not expected to have a

14

Table of Contents

material effect on ProAssurance’s results of operations, financial position or cash flows. In addition, ProAssurance's Revolving Credit Agreement contains a financial covenant regarding permitted leverage ratios based upon Consolidated Funded Indebtedness to Consolidated Total Capitalization; however, ProAssurance does not anticipate that the adoption of this guidance would have a material impact on the covenant. ProAssurance’s Mortgage Loans also contain a financial covenant regarding permitted leverage ratios, principally based upon SAP Consolidated Net Worth; however, as the NAIC is not anticipated to adopt the principles in the FASB guidance around capitalizing operating leases, adoption of the guidance would have no impact on the covenant.
Premium Amortization on Purchased Callable Debt Securities (ASU 2017-08)
Effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, the FASB issued guidance that will require the premium for certain callable debt securities to be amortized over a shorter period than is currently required. Currently amortization is permitted over the contractual life of the instrument and the guidance shortens the amortization to the earliest call date. The purpose of the guidance is to more closely align the amortization period of premiums to expectations incorporated in market pricing on the underlying securities. ProAssurance plans to adopt the guidance beginning January 1, 2019. As ProAssurance amortizes premium on callable debt securities to the earliest call date, adoption of the guidance is not expected to have a material effect on ProAssurance’s results of operations, financial position or cash flows.
Derivatives and Hedging (ASU 2017-12)
Effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, the FASB issued guidance to improve financial reporting of hedging relationships to better portray the entity's risk management activities in the consolidated financial statements. The new guidance eliminates the requirement to separately measure and report hedge ineffectiveness and requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. ProAssurance plans to adopt the guidance beginning January 1, 2019. ProAssurance's derivative instrument at September 30, 2018 is not designated as a hedging instrument; therefore, adoption is not expected to have a material effect on ProAssurance's results of operations, financial position or cash flows.
Improvements to Nonemployee Share-Based Payment Accounting (ASU 2018-07)
Effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, the FASB issued guidance which reduces the complexity in accounting for nonemployee share-based payment awards. The new guidance substantially aligns the accounting for nonemployee share-based payment awards with the accounting guidance for employee share-based payment awards with certain exceptions, including the inputs used in estimating the fair value of the nonemployee awards and the period of time and pattern of expense recognition. ProAssurance plans to adopt the guidance as of January 1, 2019. Adoption of the guidance is not expected to have a material effect on ProAssurance’s results of operations, financial position or cash flows.
Improvements to Financial Instruments - Credit Losses (ASU 2016-13)
Effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, the FASB issued guidance that replaces the incurred loss impairment methodology, which delays recognition of credit losses until a probable loss has been incurred, with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. Under the new guidance, credit losses are required to be recorded through an allowance for credit losses account and the income statement reflects the measurement for newly recognized financial assets, as well as increases or decreases of expected credit losses that have taken place during the period. Credit losses on available-for-sale fixed maturity securities will be measured in a manner similar to current GAAP, although the new guidance requires that credit losses be presented as an allowance, rather than as a write-down of the asset, limited to the amount by which the fair value is below amortized cost. In addition, this guidance could impact ProAssurance's receivables from reinsurers; however, ProAssurance has not historically experienced material credit losses due to the financial condition of a reinsurer. ProAssurance plans to adopt the guidance beginning January 1, 2020 and is in the process of evaluating the effect the new guidance would have on its results of operations and financial position.
Simplifying the Test for Goodwill Impairment (ASU 2017-04)
Effective for the fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, the FASB issued guidance that simplifies the requirements to test goodwill for impairment for business entities that have goodwill reported in their financial statements. The guidance eliminates the second step of the impairment test which measures a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount. In addition, the guidance also eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. ProAssurance plans to adopt the guidance beginning January 1, 2020. Adoption is not expected to have a material effect on ProAssurance’s results of operations, financial position or cash flows.

Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13)
Effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, the FASB issued guidance that eliminates, modifies and adds certain disclosure requirements related to fair value measurements. The new guidance eliminates the requirements to disclose the transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for the timing of transfers between levels of the fair value hierarchy and the valuation process for Level 3 fair value measurements while it modifies existing disclosure requirements related to measurement uncertainty and the requirement to disclose the timing of liquidation of an investee's assets for investments in certain entities that calculate NAV. The new guidance also adds requirements to disclose changes in unrealized gains and losses included in OCI for recurring Level 3 fair value measurements as well as the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. An entity is permitted to early adopt any eliminated or modified disclosure requirements and delay adoption of the additional disclosure requirements until the guidance is effective. As of September 30, 2018, ProAssurance has elected to early adopt the provisions that eliminate and modify certain disclosure requirements within Note 2 on a retrospective basis and adoption of these certain provisions had no material effect on ProAssurance’s results of operations, financial position or cash flows as it affected disclosures only. ProAssurance plans to adopt the additional disclosure requirements beginning January 1, 2020 and adoption is not expected to have a material effect on ProAssurance’s results of operations, financial position or cash flows.
Intangibles - Goodwill and Other-Internal-Use Software (ASU 2018-15)
Effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, the FASB amended the new standard regarding accounting for implementation costs in cloud computing arrangements. The amended guidance substantially aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. ProAssurance plans to adopt the guidance beginning January 1, 2020. Adoption is not expected to have a material effect on ProAssurance’s results of operations, financial position or cash flows.

2. Fair Value Measurement
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three level hierarchy has been established for valuing assets and liabilities based on how transparent (observable) the inputs are that are used to determine fair value, with the inputs considered most observable categorized as Level 1 and those that are the least observable categorized as Level 3. Hierarchy levels are defined as follows:
 
Level 1:
quoted (unadjusted) market prices in active markets for identical assets and liabilities. For ProAssurance, Level 1 inputs are generally quotes for debt or equity securities actively traded in exchange or over-the-counter markets.
 
Level 2:
market data obtained from sources independent of the reporting entity (observable inputs). For ProAssurance, Level 2 inputs generally include quoted prices in markets that are not active, quoted prices for similar assets or liabilities, and results from pricing models that use observable inputs such as interest rates and yield curves that are generally available at commonly quoted intervals.
 
Level 3:
the reporting entity's own assumptions about market participant assumptions based on the best information available in the circumstances (non-observable inputs). For ProAssurance, Level 3 inputs are used in situations where little or no Level 1 or 2 inputs are available or are inappropriate given the particular circumstances. Level 3 inputs include results from pricing models for which some or all of the inputs are not observable, discounted cash flow methodologies, single non-binding broker quotes and adjustments to externally quoted prices that are based on management judgment or estimation.
Fair values of assets measured at fair value on a recurring basis as of September 30, 2018 and December 31, 2017 are shown in the following tables. Where applicable, the tables also indicate the fair value hierarchy of the valuation techniques utilized to determine those fair values. For some assets, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. When this is the case, the asset is categorized based on the level of the most significant input to the fair value measurement. Assessments of the significance of a particular input to the fair value measurement require judgment and consideration of factors specific to the assets being valued.

The fair values for securities included in the Level 2 category, with the few exceptions described below, were developed by one of several third party, nationally recognized pricing services, including services that price only certain types of securities. Each service uses complex methodologies to determine values for securities and subject the values they develop to quality control reviews. Management selected a primary source for each type of security in the portfolio and reviewed the values provided for reasonableness by comparing data to alternate pricing services and to available market and trade data. Values that appeared inconsistent were further reviewed for appropriateness. Any value that did not appear reasonable was discussed with the service that provided the value and adjusted, if necessary. There were no material changes to the values supplied by the pricing services during the three and nine months ended September 30, 2018 and 2017.
Level 2 Valuations
Below is a summary description of the valuation methodologies primarily used by the pricing services for securities in the Level 2 category, by security type:
U.S. Treasury obligations were valued based on quoted prices for identical assets, or, in markets that are not active, quotes for similar assets, taking into consideration adjustments for variations in contractual cash flows and yields to maturity.
U.S. Government-sponsored enterprise obligations were valued using pricing models that consider current and historical market data, normal trading conventions, credit ratings, and the particular structure and characteristics of the security being valued, such as yield to maturity, redemption options, and contractual cash flows. Adjustments to model inputs or model results

were included in the valuation process when necessary to reflect recent regulatory, government or corporate actions or significant economic, industry or geographic events affecting the security’s fair value.
State and municipal bonds were valued using a series of matrices that considered credit ratings, the structure of the security, the sector in which the security falls, yields, and contractual cash flows. Valuations were further adjusted, when necessary, to reflect the expected effect on fair value of recent significant economic or geographic events or ratings changes.
Corporate debt, multiple observable inputs consisted primarily of corporate bonds, but also included a small number of bank loans. The methodology used to value Level 2 corporate bonds was the same as the methodology previously described for U.S. Government-sponsored enterprise obligations. Bank loans were valued based on an average of broker quotes for the loans in question, if available. If quotes were not available, the loans were valued based on quoted prices for comparable loans or, if the loan was newly issued, by comparison to similar seasoned issues. Broker quotes were compared to actual trade prices to permit assessment of the reliability of the quotes; unreliable quotes were not considered in quoted averages.
Residential and commercial mortgage-backed securities were valued using a pricing matrix which considers the issuer type, coupon rate and longest cash flows outstanding. The matrix used was based on the most recently available market information. Agency and non-agency collateralized mortgage obligations were both valued using models that consider the structure of the security, current and historical information regarding prepayment speeds, ratings and ratings updates, and current and historical interest rate and interest rate spread data.
Other asset-backed securities were valued using models that consider the structure of the security, monthly payment information, current and historical information regarding prepayment speeds, ratings and ratings updates, and current and historical interest rate and interest rate spread data. Spreads and prepayment speeds consider collateral type.
Short-term investments were securities maturing within one year, carried at fair value which approximated the cost of the securities due to their short-term nature.
 Other investments consisted primarily of convertible bonds valued using a pricing model that incorporated selected dealer quotes as well as current market data regarding equity prices and risk free rates. If dealer quotes were unavailable for the security being valued, quotes for securities with similar terms and credit status were used in the pricing model. Dealer quotes selected for use were those considered most accurate based on parameters such as underwriter status and historical reliability.
Other assets consisted of an interest rate cap derivative instrument, which is discussed in Note 9, valued using a model which considers the volatilities from other instruments with similar maturities, strike prices, durations and forward yield curves.

Level 3 Valuations
Below is a summary description of the valuation methodologies used as well as quantitative information regarding securities in the Level 3 category, by security type:
Level 3 Valuation Methodologies
Corporate debt, limited observable inputs consisted of corporate bonds valued using dealer quotes for similar securities or discounted cash flow models using yields currently available for similar securities. Similar securities are defined as securities of comparable credit quality that have like terms and payment features. Assessments of credit quality were based on NRSRO ratings, if available, or were subjectively determined by management if not available. At September 30, 2018, 79% of the securities were rated and the average rating was BBB+. At December 31, 2017, 84% of the securities were rated and the average rating was BBB+.
Residential mortgage-backed and other asset-backed securities consisted of securitizations of receivables valued using dealer quotes for similar securities or discounted cash flow models using yields currently available for similar securities. Similar securities are defined as securities of comparable credit quality that have like terms and payment features. Assessments of credit quality were based on NRSRO ratings, if available, or were subjectively determined by management if not available. At September 30, 2018, 60% of the securities were rated and the average rating was AAA. At December 31, 2017, 21% of the securities were rated and the average rating was AAA.
Other investments consisted of convertible securities for which limited observable inputs were available at September 30, 2018 and December 31, 2017. The securities were valued internally based on expected cash flows, including the expected final recovery, discounted at a yield that considered the lack of liquidity and the financial status of the issuer.

Transfers
Transfers shown in the preceding Level 3 tables were as of the end of the quarter in which the transfer occurred. All transfers were to or from Level 2.
All transfers during the three and nine months ended September 30, 2018 and 2017 related to securities held for which the level of market activity for identical or nearly identical securities varies from period to period. The securities were valued using multiple observable inputs when those inputs were available; otherwise the securities were valued using limited observable inputs.
Fair Values Not Categorized
At September 30, 2018 and December 31, 2017, certain LPs/LLCs and investment funds measure fund assets at fair value on a recurring basis and provide a NAV for ProAssurance's interest. The carrying value of these interests is based on the NAV provided and was considered to approximate the fair value of the interests. For investment in unconsolidated subsidiaries, ProAssurance recognizes any changes in the NAV of its interests in equity in earnings (loss) of unconsolidated subsidiaries during the period of change. In accordance with GAAP, the fair value of these investments was not classified within the fair value hierarchy. The amount of ProAssurance's unfunded commitments related to these investments as of September 30, 2018 and fair values of these investments as of September 30, 2018 and December 31, 2017 was as follows:

* In the first quarter of 2018, ProAssurance began presenting this investment previously reported as a part of other investments as a part of equity investments on the Condensed Consolidated Balance Sheet. Prior year amounts have not been reclassified.
Below is additional information regarding each of the investments listed in the table above as of September 30, 2018.
(1) 
This investment fund is focused on the structured mortgage market. The fund will primarily invest in U.S. Agency mortgage-backed securities. Redemptions are allowed at the end of any calendar quarter with a prior notice requirement of 65 days and are paid within 45 days at the end of the redemption dealing day.
(2) 
The investment is comprised of interests in three unrelated LP funds that are structured to provide interest distributions primarily through diversified portfolios of private debt instruments. One LP allows redemption by special consent; the other two do not permit redemption. Income and capital are to be periodically distributed at the discretion of the LPs over an anticipated time frame that spans from three to eight years.

Notes to Condensed Consolidated Financial Statements (Unaudited)
September 30, 2018

(3) 
The fund is a LP that holds long equities of public international companies. Redemptions are allowed at the end of any calendar month with a prior notice requirement of 15 days and are paid within 10 days of the end of the calendar month of the redemption request.
(4) 
The investment is comprised of interests in multiple unrelated LP funds. The funds hold primarily long and short North American equities and target absolute returns using strategies designed to take advantage of market opportunities. The funds generally permit quarterly or semi-annual capital redemptions subject to notice requirements of 30 to 90 days. For some funds, redemptions above specified thresholds (lowest threshold is 90%) may be only partially payable until after a fund audit is completed and are then payable within 30 days.
(5) 
The investment is comprised of interests in multiple unrelated LP funds, each structured to provide capital appreciation through diversified investments in private equity, which can include investments in buyout, venture capital, debt including senior, second lien and mezzanine, distressed debt and other private equity-oriented LPs. Two of the LPs allow redemption by terms set forth in the LP agreements; the others do not permit redemption. Income and capital are to be periodically distributed at the discretion of the LP over time frames that are anticipated to span up to nine years.
(6) 
This fund is a LLC structured to build and manage low volatility, multi-manager portfolios that have little or no correlation to the broader fixed income and equity security markets. Redemptions are not permitted but offers to repurchase units of the LLC may be extended periodically.
(7) 
The investment is comprised of three unrelated LP funds. Two funds seek to obtain superior risk-adjusted absolute returns through a diversified portfolio of debt securities, including bonds, loans and other asset-backed instruments. The remaining fund seeks event driven opportunities across the corporate credit spectrum. Two funds are allowed redemptions at any quarter-end with a prior notice requirement of 90 days; one fund permits redemption at any quarter-end with a prior notice requirement of 180 days.
(8) 
This fund is a LLC invested across a broad range of commodities and focuses primarily on market neutral, relative value strategies, seeking to generate absolute returns with low correlation to broad commodity, equity and fixed income markets. Following an initial one-year lock-up period, redemptions are allowed with a prior notice requirement of 30 days and are payable within 30 days.
(9) The investment is comprised of multiple unrelated LPs/LLCs funds. One fund is a LLC focused on investing in North American consumer products companies, comprised of equity and equity-related securities, as well as debt instruments. Redemptions are not permitted. Another fund is a LP focused on North American energy infrastructure assets that allows redemption with consent of the General Partner. The remaining funds are real estate focused LPs, one of which allows for redemption with prior notice.
ProAssurance may not sell, transfer or assign its interest in any of the above LPs/LLCs without special consent from the LPs/LLCs.
Nonrecurring Fair Value Measurement
At September 30, 2018, ProAssurance did not have any assets or liabilities that were measured at fair value on a nonrecurring basis. At December 31, 2017, ProAssurance held an equity method early stage business investment measured at fair value on a nonrecurring basis due to a recognized OTTI of $8.5 million. The investment was valued using significant unobservable inputs (Level 3) and had a fair value of $1.2 million at December 31, 2017. The fair value of the investment was measured as ProAssurance's ownership percentage in the projected earnings and cash flows expected to be generated by the investment.

* Carrying value excludes debt issuance costs.
The fair value of the BOLI was equal to the cash surrender value associated with the policies on the valuation date.
Other investments listed in the table above include FHLB common stock carried at cost and an annuity investment carried at amortized cost. Two of ProAssurance's insurance subsidiaries are members of an FHLB. The estimated fair value of the FHLB common stock was based on the amount the subsidiaries would receive if their memberships were canceled, as the memberships cannot be sold. The fair value of the annuity represents the present value of the expected future cash flows discounted using a rate available in active markets for similarly structured instruments.
Other assets and other liabilities primarily consisted of related investment assets and liabilities associated with funded deferred compensation agreements. The fair value of the funded deferred compensation assets was based upon quoted market prices, which is categorized as a Level 1 valuation, and had a fair value of $23.2 million and $20.2 million at September 30, 2018 and December 31, 2017, respectively. The deferred compensation liabilities are adjusted to match the fair value of the deferred compensation assets. Other assets also included a secured note receivable and unsecured note receivable under two separate line of credit agreements. Fair value of these notes receivable was based on the present value of expected cash flows from the notes receivable, discounted at market rates on the valuation date for receivables with similar credit standings and similar payment structures.
The fair value of the debt was estimated based on the present value of expected future cash outflows, discounted at rates available on the valuation date for similar debt issued by entities with a similar credit standing to ProAssurance.

As of September 30, 2018, excluding U.S. Government or U.S. Government-sponsored enterprise obligations, there were 1,090 debt securities (52.2% of all available-for-sale fixed maturity securities held) in an unrealized loss position representing 571 issuers. The greatest and second greatest unrealized loss positions among those securities were approximately $0.5 million and $0.4 million, respectively. The securities were evaluated for OTTI as of September 30, 2018.
As of December 31, 2017, excluding U.S. Government or U.S. Government-sponsored enterprise obligations, there were 629 debt securities (26.5% of all available-for-sale fixed maturity securities held) in an unrealized loss position representing 375 issuers. The greatest and second greatest unrealized loss positions among those securities were approximately $0.4 million and $0.3 million, respectively.

Each quarter, ProAssurance performs a detailed analysis for the purpose of assessing whether any of the securities it holds in an unrealized loss position has suffered an OTTI. A detailed discussion of the factors considered in the assessment is included in Note 1 of the Notes to Consolidated Financial Statements included in ProAssurance's December 31, 2017 Form 10-K.
Fixed maturity securities held in an unrealized loss position at September 30, 2018, excluding asset-backed securities, have paid all scheduled contractual payments and are expected to continue doing so. Expected future cash flows of asset-backed securities, excluding those issued by GNMA, FNMA and FHLMC, held in an unrealized loss position were estimated as part of the September 30, 2018 OTTI evaluation using the most recently available six-month historical performance data for the collateral (loans) underlying the security or, if historical data was not available, sector based assumptions, and equaled or exceeded the current amortized cost basis of the security.

Equity Investments
ProAssurance's equity investments are carried at fair value with changes in fair value recognized in income as a component of net realized investment gains (losses) during the period of change. Equity investments on the Condensed Consolidated Balance Sheet as of September 30, 2018 primarily included stocks, bonds and investment funds.
Short-term Investments
ProAssurance's short-term investments, which have a maturity at purchase of one year or less, are primarily comprised of investments in U.S. treasury obligations, commercial paper and money market funds. Short-term investments are carried at fair value which approximates the cost of the securities due to their short-term nature.
BOLI
ProAssurance holds BOLI policies that are carried at the current cash surrender value of the policies (original cost $33 million). All insured individuals were members of ProAssurance management at the time the policies were acquired. The primary purpose of the program is to offset future employee benefit expenses through earnings on the cash value of the policies. ProAssurance is the owner and beneficiary of these policies.

Qualified affordable housing project tax credit partnership interests held by ProAssurance generate investment returns by providing tax benefits to fund investors in the form of tax credits and project operating losses. The carrying value of these investments reflects ProAssurance's total commitments (both funded and unfunded) to the partnerships, less any amortization. ProAssurance's ownership percentage relative to two of the tax credit partnership interests is almost 100%; these interests had a carrying value of $26.7 million at September 30, 2018 and $32.5 million at December 31, 2017. ProAssurance's ownership percentage relative to the remaining tax credit partnership interests is less than 20%; these interests had a carrying value of $43.5 million at September 30, 2018 and $52.1 million at December 31, 2017. Since ProAssurance has the ability to exert influence over the partnerships but does not control them, all are accounted for using the equity method. See further discussion of the entities in which ProAssurance holds passive interests in Note 11.
Other tax credit partnerships are comprised entirely of investments in historic tax credit partnerships. The historic tax credit partnerships generate investment returns by providing benefits to fund investors in the form of tax credits, tax deductible project operating losses and positive cash flows. The carrying value of these investments reflects ProAssurance's total funded commitments less any amortization. ProAssurance's ownership percentage relative to the historic tax credit partnerships is almost 100%. Since ProAssurance has the ability to exert influence over the partnerships but does not control them, all are accounted for using the equity method. See further discussion of the entities in which ProAssurance holds passive interests in Note 11.
ProAssurance holds interests in investment fund LPs/LLCs and other equity method investments and LPs/LLCs which are not considered to be investment funds. ProAssurance's ownership percentage relative to one of the LPs/LLCs is greater than 25%, which is expected to be reduced as the funds mature and other investors participate in the funds; these investments had a carrying value of $24.1 million at September 30, 2018 and $30.8 million at December 31, 2017. ProAssurance's ownership percentage relative to the remaining investments and LPs/LLCs is less than 25%; these interests had a carrying value of $292.0 million at September 30, 2018 and $209.1 million at December 31, 2017. ProAssurance does not have the ability to exert control over any of these funds.
Equity in Earnings (Loss) of Unconsolidated Subsidiaries
Equity in earnings (loss) of unconsolidated subsidiaries included losses from qualified affordable housing project tax credit partnerships and historic tax credit partnerships. Losses recorded reflect ProAssurance's allocable portion of partnership operating losses. Tax credits reduce income tax expense in the period they are recognized.

4. Retroactive Insurance Contracts
ProAssurance offers custom alternative risk solutions including loss portfolio transfers for large healthcare entities who, most commonly, are exiting a line of business, changing an insurance approach or simply preferring to transfer risk. A loss portfolio transfer is a form of retroactive insurance coverage as the Company is assuming and accepting an entity’s existing open and future claim liabilities through the transfer of the entity’s loss reserves.
In the second quarter of 2018, ProAssurance entered into a loss portfolio transfer with a large healthcare organization. Per the agreement, ProAssurance will cover a specific inventory of existing claims as well as provide tail coverage. As the contract included both prospective (tail) coverage and retroactive coverage, ProAssurance bifurcated the provisions of the contract and accounted for each component separately. As of the contract effective date, ProAssurance recognized total net premiums written and earned of $26.6 million, comprised of $7.9 million of prospective coverage and $18.7 million of retroactive coverage, and total net losses and loss adjustment expenses of $25.4 million in the Condensed Consolidated Statements of Income and Comprehensive Income for the nine months ended September 30, 2018. In addition, ProAssurance recorded a deferred gain of $0.6 million in the reserve for losses and loss adjustment expenses on the Condensed Consolidated Balance Sheet in the second quarter of 2018 representing the excess of premiums received over losses assumed related to the retroactive coverage which are amortized into earnings over the estimated claim payment period. Amortization of this deferred gain was insignificant for the three and nine months ended September 30, 2018. For additional information regarding ProAssurance's accounting policy for retroactive insurance contracts, see Note 1.
5. Income Taxes
ProAssurance estimates its annual effective tax rate at the end of each quarterly reporting period and uses this estimated rate to record the provision for income taxes in the interim financial statements. The provision for income taxes is different from that which would be obtained by applying the statutory federal income tax rate to income before income taxes primarily because a portion of ProAssurance’s investment income is tax-exempt, and because ProAssurance utilizes tax credit benefits transferred from tax credit partnership investments. In addition, ProAssurance's provision for income taxes in 2018 was impacted by certain provisions of the TCJA, as discussed below.
ProAssurance had a total liability for federal and U.K. income taxes of $2.1 million at September 30, 2018 and $8.0 million at December 31, 2017, both carried as a part of other liabilities. The liability for unrecognized tax benefits, which is included in the total liability for federal and U.K. income taxes, was $5.1 million and $5.8 million at September 30, 2018 and December 31, 2017, respectively, which included an accrued liability for interest of approximately $0.6 million and $0.5 million, respectively.
Tax Cuts and Jobs Act
The TCJA was signed into law on December 22, 2017 and contains several key provisions that impact the Company's business, including the reduction of the U.S. federal corporate tax rate from 35% to 21% effective January 1, 2018, the reduction in the amount of executive compensation that could qualify as a tax deduction, a minimum tax on payments made to related foreign entities and a change in how property and casualty taxpayers discount loss reserves.
Effective January 1, 2018, the TCJA introduced a minimum tax on payments made to related foreign entities referred to as the BEAT. The BEAT is imposed by adding back into the U.S. tax base any base erosion payment made by the U.S. taxpayer to a related foreign entity and applying a minimum tax rate to this newly calculated modified taxable income. Base erosion payments represent any amount paid or accrued by the U.S. taxpayer to a related foreign entity for which a deduction is allowed. Premiums the Company cedes to the SPCs at its newly formed wholly owned Cayman Islands reinsurance subsidiary, Inova Re, do not fall within the scope of base erosion payments as the SPCs at Inova Re intend to elect to be taxed as U.S. taxpayers. However, premiums the Company cedes to any active SPC at its wholly owned Cayman Islands reinsurance subsidiary, Eastern Re, fall within the scope of base erosion payments and therefore could be significantly impacted by the BEAT. See further discussion on the Company’s new subsidiary, Inova Re, and its Cayman Islands SPC operations in Note 13. Management has evaluated its exposure to the BEAT and has concluded that the Company’s expected outbound deductible payments to related foreign entities are below the threshold for application of the BEAT; therefore, ProAssurance has not recognized any incremental tax expense for the BEAT provision of the TCJA for the three and nine months ended September 30, 2018.

As noted in ProAssurance's December 31, 2017 Form 10-K, ProAssurance was able to make a reasonable estimate of the effects on its existing deferred tax asset balances at December 31, 2017 as it relates to the limitation on the future deductibility of certain executive compensation and recorded a provisional charge to income tax expense from continuing operations for the year ended December 31, 2017. During the third quarter of 2018, the IRS issued guidance addressing the effects of the TCJA on executive compensation; therefore, ProAssurance was able to complete its accounting for the impact of the TCJA on the ProAssurance's December 31, 2017 deferred tax asset balances related to executive compensation. As a result, ProAssurance did not record any measurement-period adjustments to the previously recorded provisional amount.
Provisional amount not reasonably estimable
As noted in ProAssurance's December 31, 2017 Form 10-K, ProAssurance was unable to reasonably estimate the impact of the change in loss reserve discounting factors due to the TCJA; therefore, no provisional amount was recorded at December 31, 2017. As of September 30, 2018, the IRS has yet to release the 2018 discount factors; therefore, ProAssurance has not adjusted its deferred tax balances due to the enactment of the TCJA. ProAssurance continues to utilize the discount factors based on existing accounting guidance and the provisions of the tax laws that were in effect immediately prior to enactment of the TCJA. Once the IRS releases the 2018 loss reserve discount factors, ProAssurance will complete its analysis and include the effect of the difference in the reserve discount factors in the period the analysis is complete or the impact is reasonably estimable.
6. Reserve for Losses and Loss Adjustment Expenses
The reserve for losses is established based on estimates of individual claims and actuarially determined estimates of future losses based on ProAssurance’s past loss experience, available industry data and projections as to future claims frequency, severity, inflationary trends and settlement patterns. Estimating the reserve, particularly the reserve appropriate for liability exposures, is a complex process. Claims may be resolved over an extended period of time, often five years or more, and may be subject to litigation. Estimating losses requires ProAssurance to make and revise judgments and assessments regarding multiple uncertainties over an extended period of time. As a result, the reserve estimate may vary considerably from the eventual outcome. The assumptions used in establishing ProAssurance’s reserve are regularly reviewed and updated by management as new data becomes available. Changes to estimates of previously established reserves are included in earnings in the period in which the estimate is changed.
ProAssurance believes that the methods it uses to establish reserves are reasonable and appropriate. Each year, ProAssurance uses internal actuaries to review the reserve for losses of each insurance subsidiary. ProAssurance also engages consulting actuaries to review ProAssurance claims data and provide observations regarding cost trends, rate adequacy and ultimate loss costs. ProAssurance considers the views of the actuaries as well as other factors, such as known, anticipated or estimated changes in frequency and severity of claims, loss retention levels and premium rates, in establishing the amount of its reserve for losses. The statutory filings of each insurance company with the insurance regulators must be accompanied by a consulting actuary's certification as to their respective reserves.
ProAssurance partitions its reserve by accident year, which is the year in which the claim becomes its liability. As claims are incurred (reported) and claim payments are made, they are aggregated by accident year for analysis purposes. ProAssurance also partitions its reserve by reserve type: case reserves and IBNR reserves. Case reserves are established by the claims department based upon the particular circumstances of each reported claim and represent ProAssurance’s estimate of the future loss costs (often referred to as expected losses) that will be paid on reported claims. Case reserves are decremented as claim payments are made and are periodically adjusted upward or downward as estimates regarding the amount of future losses are revised; a reported loss for an individual claim equates to the case reserve at any point in time plus the claim payments that have been made to date. IBNR reserves represent an estimate, in the aggregate, of future development on losses that have been reported to ProAssurance plus an estimate of losses that have been incurred but not reported.
Development of Prior Accident Years
In addition to setting the initial reserve for the current accident year, each period ProAssurance reassesses the amount of reserve required for prior accident years. The foundation of ProAssurance’s reserve re-estimation process is an actuarial analysis that is performed by both the internal and consulting actuaries. This detailed analysis projects ultimate losses based on partitions which include line of business, geography, coverage layer and accident year. The procedure uses the most representative data for each partition, capturing its unique patterns of development and trends. In all, there are 200 different

partitions of ProAssurance's business for purposes of this analysis. ProAssurance believes that the use of consulting actuaries provides an independent view of the loss data as well as a broader perspective on industry loss trends.

* Current year net losses during the 2018 nine-month period included incurred losses of $25.4 million related to a loss portfolio transfer entered into during the second quarter of 2018 (see Note 4).
The favorable loss development of $67.1 million recognized in the nine months ended September 30, 2018 primarily reflected a lower than anticipated claims severity trend (i.e., the average size of a claim) for accident years 2011 through 2015. The favorable loss development of $90.1 million recognized in the nine months ended September 30, 2017 primarily reflected a lower than anticipated claims severity trend for accident years 2010 through 2014. The favorable loss development of $134.4 million recognized in the twelve months ended December 31, 2017 primarily reflected a lower than anticipated claims severity trend for accident years 2010 through 2014.
For additional information regarding ProAssurance's reserve for losses, see Note 1 and Note 7 of the Notes to Consolidated Financial Statements included in ProAssurance's December 31, 2017 Form 10-K.
7. Commitments and Contingencies
ProAssurance is involved in various legal actions related to insurance policies and claims handling including, but not limited to, claims asserted by policyholders. These types of legal actions arise in the Company's ordinary course of business and, in accordance with GAAP for insurance entities, are considered as a part of the Company's loss reserving process, which is described in detail under the heading "Losses and Loss Adjustment Expenses" in the Accounting Policies section in Note 1 of the Notes to Consolidated Financial Statements in ProAssurance's 2017 Form 10-K.
As a member of Lloyd's, ProAssurance is required to provide capital to support its Lloyd's Syndicates through 2022 of up to $200 million, referred to as FAL. At September 30, 2018, ProAssurance is satisfying the FAL requirement with investment securities on deposit with Lloyd's with a carrying value of $125.4 million (see Note 3).
ProAssurance has issued an unconditional revolving credit agreement to the Premium Trust Fund of Syndicate 1729 for the purpose of providing working capital. Permitted borrowings were expanded from £20.0 million to £30.0 million under an amended Syndicate Credit Agreement executed in February 2018. Under the amended Syndicate Credit Agreement, advances bear interest at 3.8% annually and may be repaid at any time but are repayable upon demand after December 31, 2019. As of September 30, 2018, the unused commitment under the Syndicate Credit Agreement approximated £8.8 million (approximately $11.5 million).

On occasion, ProAssurance has entered into financial instrument transactions that may present off-balance sheet credit risk or market risk. These transactions include a short-term loan commitment and commitments to provide funding to non-public investment entities. Under the short-term loan commitment, ProAssurance has agreed to advance funds on a 30 day basis to a counterparty provided there is no violation of any condition established in the contract. As of September 30, 2018, ProAssurance had total funding commitments of approximately $272.1 million which primarily represented funding commitments related to non-public investment entities as well as a short-term loan commitment which included the amount at risk if the full short-term loan is extended and the counterparties default. However, the credit risk associated with the short-term loan commitment is minimal as the counterparties to the contract are highly rated commercial institutions and to-date have been performing in accordance with their contractual obligations.

9. Derivatives
ProAssurance is exposed to certain risks relating to its ongoing business and investment activities. ProAssurance utilizes derivative instruments as part of its risk management strategy to reduce the market risk related to fluctuations in future interest rates associated with a portion of its variable-rate debt. As of September 30, 2018, ProAssurance has not designated any derivative instruments as hedging instruments and does not use derivative instruments for trading purposes.
ProAssurance utilizes an interest rate cap agreement with the objective of reducing the Company's exposure to interest rate risk related to its variable-rate Mortgage Loans. Additional information regarding the Company's Mortgage Loans is provided in Note 8. Under the terms of the interest rate cap agreement, ProAssurance paid a premium of $2 million in the fourth quarter of 2017 for the right to receive cash payments based upon a notional amount of $35 million if and when the three-month LIBOR rises above 2.35%. The Company's variable-rate Mortgage Loans bear an interest rate of three-month LIBOR plus 1.325%. Therefore, this derivative instrument is effectively ensuring the interest rate related to the Mortgage Loans is capped at a maximum of 3.675% until expiration of the interest rate cap agreement in October 2027. ProAssurance has designated the interest rate cap as an economic hedge (non-hedging instrument) of interest rate exposure and any change in fair value of the derivative is immediately recognized in earnings during the period of change.
The following table provides a summary of the volume and fair value position of the interest rate cap as well as the reporting location in the Condensed Consolidated Balance Sheets as of September 30, 2018 and December 31, 2017.

10. Shareholders’ Equity
At September 30, 2018 and December 31, 2017, ProAssurance had 100 million shares of authorized common stock and 50 million shares of authorized preferred stock. The Board has the authority to determine provisions for the issuance of preferred shares, including the number of shares to be issued, the designations, powers, preferences and rights, and the qualifications, limitations or restrictions of such shares. To date, the Board has not approved the issuance of preferred stock.
ProAssurance declared cash dividends of $0.31 per share during each of the first three quarters of both 2018 and 2017, totaling $50.9 million and $49.6 million, for each respective nine-month period.
At September 30, 2018, Board authorizations for the repurchase of common shares or the retirement of outstanding debt of $109.6 million remained available for use. ProAssurance did not repurchase any common shares during the nine months ended September 30, 2018 and 2017.

ProAssurance awarded approximately 85,800 restricted share units and 27,200 base performance share units to employees in February 2018. The fair value of each unit awarded was estimated at $44.73, equal to the market value of a ProAssurance common share on the date of grant less the estimated present value of dividends during the vesting period. The majority of awards are charged to expense as an increase to additional paid-in capital over the service period (generally the vesting period) associated with the award. However, a nominal amount of awards are recorded as a liability as they are structured to be settled in cash. Restricted share units and performance share units vest in their entirety at the end of a three-year period following the grant date based on a continuous service requirement and, for performance share units, achievement of a performance objective. Partial vesting is permitted for retirees. For equity classified awards, a ProAssurance common share is issued for each unit once vesting requirements are met, except that units sufficient to satisfy required tax withholdings are paid in cash. The number of common shares issued for performance share units varies from 50% to 200% of base awards depending upon the degree to which stated performance objectives are achieved. ProAssurance issued approximately 52,800 and 80,600 common shares to employees in February 2018 related to restricted share units and performance share units, respectively, granted in 2015. Performance share units for the 2015 award were issued at a level of 125%. Liability classified awards, which are nominal in amount, are settled in cash at the end of the vesting period.
ProAssurance issued approximately 2,500 common shares to employees in February 2018 as bonus compensation, as approved by the Compensation Committee of the Board. The shares issued were valued at fair value (the market price of a ProAssurance common share on the date of award).
Other Comprehensive Income (Loss) and Accumulated Other Comprehensive Income (Loss)
For the three and nine months ended September 30, 2018 and 2017, OCI was almost entirely comprised of unrealized gains and losses, including non-credit impairment losses, arising during the period related to fixed maturity available-for-sale securities, less reclassification adjustments, as shown in the table that follows, net of tax. For the three and nine months ended September 30, 2018 and 2017, OCI included changes related to the reestimation of the defined benefit plan liability assumed in the Eastern acquisition which were nominal in amount. The defined benefit plan is frozen as to the earnings of additional benefits and the benefit plan liability is reestimated annually.
At September 30, 2018 and December 31, 2017, AOCI was almost entirely comprised of accumulated unrealized gains and losses from fixed maturity available-for-sale securities, including accumulated non-credit impairments recognized through OCI of $0.1 million and $0.5 million, respectively, net of tax. At September 30, 2018 and December 31, 2017, accumulated changes in the defined benefit plan liability not yet recognized in earnings were nominal in amount. Due to the adoption of accounting guidance in the first quarter of 2018 related to certain impacts of the TCJA, ProAssurance increased AOCI by approximately $3.4 million with a corresponding decrease to retained earnings of the same amount as of the beginning of 2018. See Note 1 for additional information on accounting guidance adopted during the period. At September 30, 2018 and December 31, 2017, tax effects were computed using the enacted federal corporate tax rate of 21% and 35%, respectively, with the exception of unrealized gains and losses on available-for-sale securities held at our U.K. and Cayman Islands entities which in both periods were immaterial in amount.

11. Variable Interest Entities
ProAssurance holds passive interests in a number of entities that are considered to be VIEs under GAAP guidance. ProAssurance's VIE interests principally consist of interests in LPs/LLCs formed for the purpose of achieving diversified equity and debt returns. At September 30, 2018, ProAssurance's VIE interests totaled $304.7 million carried as a part of investment in unconsolidated subsidiaries.
ProAssurance does not have power over the activities that most significantly impact the economic performance of these VIEs and thus is not the primary beneficiary. Therefore, ProAssurance has not consolidated these VIEs. ProAssurance’s involvement with each VIE is limited to its direct ownership interest in the VIE. Except for the funding commitments disclosed in Note 7, ProAssurance has no arrangements with any of the VIEs to provide other financial support to or on behalf of the VIE. At September 30, 2018, ProAssurance’s maximum loss exposure relative to these investments was limited to the carrying value of ProAssurance’s investment in the VIE.
12. Earnings Per Share
Diluted weighted average shares is calculated as basic weighted average shares plus the effect, calculated using the treasury stock method, of assuming that restricted share units, performance share units and purchase match units have vested. The following table provides the weighted average number of common shares outstanding used in the calculation of the Company's basic and diluted earnings per share:

There were no antidilutive common share equivalents for the three months ended September 30, 2018. The diluted weighted average number of common shares outstanding for the nine months ended September 30, 2018 excludes approximately 3,000 common share equivalents issuable under the Company's stock compensation plans, while the three and nine months ended September 30, 2017 periods exclude 28,000 and 9,000 common share equivalents, respectively, as their effect would be antidilutive.

13. Segment Information
ProAssurance's segments are based on the Company's internal management reporting structure for which financial results are regularly evaluated by the Company's CODM to determine resource allocation and assess operating performance. The Company continually assesses its internal management reporting structure and information evaluated by the CODM to determine whether any changes have occurred that would impact its segment reporting structure.
Segment Reorganization
During the third quarter of 2018, ProAssurance altered its internal management reporting structure and the financial results evaluated by its CODM; therefore, ProAssurance changed its operating segments to align with how the CODM currently oversees the business, allocates resources and evaluates operating performance. As a result of the segment reorganization, ProAssurance added an operating and reportable segment: Segregated Portfolio Cell Reinsurance.
The Segregated Portfolio Cell Reinsurance segment provides the operating results of SPCs that assume workers’ compensation insurance, healthcare professional liability insurance or a combination of the two. The underwriting results of the SPCs that assume workers’ compensation business and healthcare professional liability business were previously reported in the Company's Workers’ Compensation and Specialty P&C segments, respectively, and the results of investment assets solely allocated to SPC operations, previously reported in the Company's Corporate segment, are now reported in the Segregated Portfolio Cell Reinsurance segment. The Workers' Compensation segment has also been renamed "Workers' Compensation Insurance." All prior period segment information has been recast to conform to the current period presentation. The segment reorganization had no impact on previously reported consolidated financial results.
Descriptions of ProAssurance's five operating and reportable segments are as follows:
Specialty P&C is primarily focused on professional liability insurance and medical technology liability insurance. Professional liability insurance is primarily offered to healthcare providers and institutions and to attorneys and their firms. Medical technology liability insurance is offered to medical technology and life sciences companies that manufacture or distribute products including entities conducting human clinical trials. Prior to 2018, the Specialty P&C segment ceded certain premium to the Lloyd's Syndicates segment under a quota share agreement with Syndicate 1729; however, this agreement was not renewed on January 1, 2018. As discussed below, the Lloyd's Syndicates segment results are typically reported on a quarter delay. For consistency purposes, results from this ceding arrangement, other than cash receipts or disbursements, are reported within the Specialty P&C segment on the same one-quarter delay. Additionally, the Specialty P&C segment cedes healthcare professional liability business to certain SPCs in the Company's Segregated Portfolio Cell Reinsurance segment.
Workers' Compensation Insurance provides workers' compensation products primarily to employers with 1,000 or fewer employees. The segment's products include guaranteed cost, policyholder dividend policies, retrospectively-rated policies, deductible polices and alternative market solutions. Alternative market products include program design, fronting, claims administration, risk management, SPC rental, asset management and SPC management services. Alternative market premiums are 100% ceded to either SPCs in the Company's Segregated Portfolio Cell Reinsurance segment or, to a limited extent, to captive insurers unaffiliated with ProAssurance.
Segregated Portfolio Cell Reinsurance reflects the operating results (underwriting profit or loss, plus investment results) of SPCs at Eastern Re and Inova Re, the Company's Cayman Islands SPC operations. The SPCs assume workers' compensation insurance, healthcare professional liability insurance or a combination of the two from the Workers' Compensation Insurance and Specialty P&C segments. Each SPC is owned, fully or in part, by an agency, group or association and the operating results of the SPCs are due to the owners of that cell. ProAssurance participates to a varying degree in the results of selected SPCs. SPC operating results due to external cell owners are reflected as a SPC dividend expense in the Segregated Portfolio Cell Reinsurance segment and in ProAssurance's Condensed Consolidated Statements of Income and Comprehensive Income. In addition, the Segregated Portfolio Cell Reinsurance segment includes the SPC investment results as the investments are solely for the benefit of the cell participants and investment results due to external cell owners are reflected in the SPC dividend expense. The segment operating results reflects ProAssurance's share of the underwriting and investment results of the SPCs in which ProAssurance participates.
During the first quarter of 2018, ProAssurance restructured its Cayman Islands SPC operations. Beginning in 2018, all new and renewing alternative market business previously ceded to the SPCs at Eastern Re, with the exception of one program, is now ceded to SPCs operated by a newly formed wholly owned Cayman Islands subsidiary, Inova Re. As part of the restructuring, all SPCs previously operated by Eastern Re, with the exception of one program, ceased assuming new and renewing business on or after January 1, 2018. The external cell owners' cumulative undistributed earnings and the results of all SPCs for the current period due to external cell owners continue to be reported as SPC dividends payable and SPC dividend expense, respectively.

Notes to Condensed Consolidated Financial Statements (Unaudited)
September 30, 2018

Lloyd's Syndicates includes operating results from ProAssurance's participation in Lloyd's of London Syndicate 1729 and Syndicate 6131, which is a SPA that began writing business effective January 1, 2018. The results of this segment are normally reported on a quarter delay, except when information is available that is material to the current period. Furthermore, investment results associated with the majority of investment assets solely allocated to Lloyd's Syndicate operations and certain U.S. paid administrative expenses are reported concurrently as that information is available on an earlier time frame. Beginning in 2018, ProAssurance increased its participation in the operating results of Syndicate 1729 from 58% to 62% and began its 100% participation in the operating results of Syndicate 6131; however, due to the quarter delay these changes were not reflected in the Lloyd's Syndicates segment results until the second quarter of 2018. Syndicate 1729 underwrites risks over a wide range of property and casualty insurance and reinsurance lines in both the U.S. and international markets. Syndicate 6131 focuses on contingency and specialty property business, also within the U.S. and international markets.
Corporate includes ProAssurance's investment operations, interest expense and U.S. income taxes, all of which are managed at the corporate level with the exception of investment assets solely allocated to either SPC operations or Lloyd's Syndicate operations, as previously discussed. The segment also includes non-premium revenues generated outside of the Company's insurance entities and corporate expenses.
The accounting policies of the segments are the same as those described in Note 1 of the Notes to Consolidated Financial Statements in ProAssurance’s December 31, 2017 report on Form 10-K and Note 1 of the Notes to Condensed Consolidated Financial Statements. ProAssurance evaluates the performance of its Specialty P&C and Workers' Compensation Insurance segments based on before tax underwriting profit or loss, which excludes investment performance. ProAssurance evaluates the performance of its Segregated Portfolio Cell Reinsurance segment based on before tax operating profit or loss, which includes the investment performance of assets solely allocated to SPC operations. Performance of the Lloyd's Syndicates segment is evaluated based on underwriting profit or loss, plus investment results of investment assets solely allocated to Lloyd's Syndicate operations, net of U.K. income tax expense. Performance of the Corporate segment is evaluated based on the contribution made to consolidated after-tax results. ProAssurance accounts for inter-segment transactions as if the transactions were to third parties at current market prices. Assets are not allocated to segments because investments, other than the investments discussed above that are solely allocated to the Segregated Portfolio Cell Reinsurance and Lloyd's Syndicates segments, and other assets are not managed at the segment level.

(1) As a result of the third quarter 2018 segment reorganization, certain fees for services provided to the SPCs at Eastern Re and Inova Re are recorded as expenses within the Segregated Portfolio Cell Reinsurance segment and as other income within the Workers' Compensation Insurance segment. These fees are eliminated between segments in consolidation. These services primarily include SPC rental fees and were previously eliminated within the Company's Workers' Compensation segment.
(2) During the second quarter of 2017, ProAssurance recognized a $5.2 million pre-tax expense related to previously unrecognized SPC dividend expense for the cumulative earnings of unrelated parties that have owned segregated portfolio cells at various periods since 2003 in a Bermuda captive insurance operation managed by the Company's HCPL line of business within the Specialty P&C segment. The expense recorded in the second quarter of 2017 related to periods prior to the then current period and was unrelated to the captive operations of the Company's Eastern Re subsidiary. The $1.8 million tax impact of the expense recognized in the second quarter of 2017 was included in the Corporate segment's income tax benefit (expense).

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.
The following discussion should be read in conjunction with the Condensed Consolidated Financial Statements and Notes to those statements which accompany this report. Throughout the discussion we use certain terms and abbreviations, which can be found in the Glossary of Terms and Acronyms at the beginning of this report. In addition, a glossary of insurance terms and phrases is available on the investor section of our website. Throughout the discussion, references to "ProAssurance," "PRA," "Company," "we," "us" and "our" refer to ProAssurance Corporation and its consolidated subsidiaries. The discussion contains certain forward-looking information that involves significant risks, assumptions and uncertainties. As discussed under the heading "Caution Regarding Forward-Looking Statements," our actual financial condition and operating results could differ significantly from these forward-looking statements.
ProAssurance Overview
ProAssurance Corporation is a holding company for property and casualty insurance companies. Our wholly owned insurance subsidiaries provide professional liability insurance for healthcare professionals and facilities, professional liability insurance for attorneys, liability insurance for medical technology and life sciences risks and workers' compensation insurance. We are also the majority capital provider for Syndicate 1729 and the sole capital provider for Syndicate 6131.
Our segments are based on our internal management reporting structure for which financial results are regularly evaluated by our CODM to determine resource allocation and assess operating performance. During the third quarter of 2018, we reorganized our segment reporting and as a result, the number of our segments increased from four to five, described as follows:
Specialty P&C - This segment includes our professional liability business and medical technology liability business. Professional liability insurance is primarily offered to healthcare providers and institutions and to attorneys and their firms. Medical technology liability insurance is offered to medical technology and life sciences companies that manufacture or distribute products including entities conducting human clinical trials. The underwriting results of SPCs that assume healthcare professional liability business were previously reported in this segment and are now reported in our Segregated Portfolio Cell Reinsurance segment.
Workers' Compensation Insurance - This segment includes our workers' compensation insurance business which is provided primarily to employers with 1,000 or fewer employees. Our workers' compensation products include guaranteed cost, policyholder dividend policies, retrospectively-rated policies, deductible policies and alternative market solutions. The underwriting results of SPCs that assume workers’ compensation business were previously reported in this segment and are now reported in our Segregated Portfolio Cell Reinsurance segment.
Segregated Portfolio Cell Reinsurance - This segment reflects the operating results (underwriting profit or loss, plus investment results) of SPCs at Eastern Re and Inova Re, our Cayman Islands SPC operations. The SPCs assume workers' compensation insurance, healthcare professional liability insurance or a combination of the two from our Workers' Compensation Insurance and Specialty P&C segments.
Lloyd's Syndicates - This segment includes the operating results from our participation (62% for 2018) in Lloyd's of London Syndicate 1729 and our 100% participation in Syndicate 6131, which is a SPA that began writing business effective January 1, 2018. The results of this segment are normally reported on a quarter delay, except when information is available that is material to the current period. Syndicate 1729 underwrites risks over a wide range of property and casualty insurance and reinsurance lines in both the U.S. and international markets while Syndicate 6131 focuses on contingency and specialty property business, also within the U.S. and international markets.
Corporate - This segment includes our investment operations, interest expense and U.S. income taxes, all of which are managed at the corporate level with the exception of investment assets solely allocated to either SPC operations or Lloyd's Syndicate operations. The results of investment assets solely allocated to SPC operations were previously reported in this segment and are now reported in our Segregated Portfolio Cell Reinsurance segment. This segment also includes non-premium revenues generated outside of our insurance entities and corporate expenses.
All prior period segment information has been recast to conform to the current period presentation and the segment reorganization had no impact on previously reported consolidated financial results. Additional information regarding our segments is included in Note 13 of the Notes to Condensed Consolidated Financial Statements and the Segment Operating Results sections that follow.

Table of Contents

Critical Accounting Estimates
Our Condensed Consolidated Financial Statements are prepared in conformity with GAAP. Preparation of these financial statements requires us to make estimates and assumptions that affect the amounts we report on those statements. We evaluate these estimates and assumptions on an ongoing basis based on current and historical developments, market conditions, industry trends and other information that we believe to be reasonable under the circumstances. There can be no assurance that actual results will conform to our estimates and assumptions; reported results of operations may be materially affected by changes in these estimates and assumptions.
Management considers the following accounting estimates to be critical because they involve significant judgment by management and those judgments could result in a material effect on our financial statements.
Reserve for Losses and Loss Adjustment Expenses
The largest component of our liabilities is our reserve for losses and loss adjustment expenses ("reserve for losses" or "reserve"), and the largest component of expense for our operations is incurred losses and loss adjustment expenses (also referred to as “losses and loss adjustment expenses,” “incurred losses,” “losses incurred” and “losses”). Incurred losses reported in any period reflect our estimate of losses incurred related to the premiums earned in that period as well as any changes to our previous estimate of the reserve required for prior periods.
As of September 30, 2018, our reserve is comprised almost entirely of long-tail exposures. The estimation of long-tailed losses is inherently difficult and is subject to significant judgment on the part of management. Due to the nature of our claims, our loss costs, even for claims with similar characteristics, can vary significantly depending upon many factors, including but not limited to the specific characteristics of the claim and the manner in which the claim is resolved. Long-tailed insurance is characterized by the extended period of time typically required both to assess the viability of a claim and potential damages, if any, and to reach a resolution of the claim. The claims resolution process may extend to more than five years. The combination of continually changing conditions and the extended time required for claim resolution results in a loss cost estimation process that requires actuarial skill and the application of significant judgment, and such estimates require periodic modification.
Our reserve is established by management after taking into consideration a variety of factors including premium rates, claims frequency and severity, historical paid and incurred loss development trends, the expected effect of inflation, general economic trends, the legal and political environment and the conclusions reached by our internal and consulting actuaries. We update and review the data underlying the estimation of our reserve for losses each reporting period and make adjustments to loss estimation assumptions that we believe best reflect emerging data. Both our internal and consulting actuaries perform an in-depth review of our reserve for losses on at least a semi-annual basis using the loss and exposure data of our insurance subsidiaries.
Our reserving process can be broadly grouped into three areas: the establishment of the reserve for the current accident year (the initial reserve), the re-estimation of the reserve for prior accident years (development of prior accident years) and the establishment of the initial reserve for risks assumed in business combinations, applicable only in periods in which acquisitions occur (the acquired reserve).
Current Accident Year - Initial Reserve
Considerable judgment is required in establishing our initial reserve for any current accident year period, as there is limited data available upon which to base our estimate. Our process for setting an initial reserve considers the unique characteristics of each product, but in general we rely heavily on the loss assumptions that were used to price business, as our pricing reflects our analysis of loss costs that we expect to incur relative to the insurance product being priced.
Specialty P&C Segment. Loss costs within this segment are impacted by many factors, including but not limited to the nature of the claim, including whether or not the claim is an individual or a mass tort claim, the personal situation of the claimant or the claimant's family, the outcome of jury trials, the legislative and judicial climate where any potential litigation may occur, general economic conditions and, for claims involving bodily injury, the trend of healthcare costs. Within our Specialty P&C segment, for our HCPL business (74% of our consolidated gross reserve for losses and loss adjustment expenses as of December 31, 2017), we set an initial reserve using the average loss ratio used in our pricing, plus an additional provision in consideration of the historical loss volatility we and others in the industry have experienced. The current accident year reserve also includes provisions for any loss portfolio transfers we enter into during the current period. For our HCPL business our target loss ratio during recent accident years has ranged from 77% to 80% and the provision for loss volatility has ranged from 8 to 10 percentage points, producing an overall average initial loss ratio for our HCPL business of approximately 90%. Changes in observed claim frequency and/or severity can result in variations from these levels. The reasons for the variability in loss provisions from period to period have included additional loss activity within our excess and surplus lines business, provisions for losses in excess of policy limits, adjustments to unallocated loss adjustment expenses, adjustment to the reserve for the death, disability and retirement provisions in our policies and additional losses recorded for particular exposures, such

as mass torts. These specific adjustments are made if we believe the results for a given accident year are likely to exceed those anticipated by our pricing. We believe use of a provision for volatility appropriately considers the inherent risks and limitations of our rate development process and the historic volatility of professional liability losses (the industry has experienced accident year loss ratios as high as 138% and as low as 54% over the past 30 years) and produces a reasonable best estimate of the reserve required to cover actual ultimate unpaid losses. A similar practice is followed for our legal professional liability business (3% of our consolidated gross reserve for losses and loss adjustment expenses as of December 31, 2017).
The risks insured in our medical technology liability business (5% of our consolidated gross reserve for losses and loss adjustment expenses as of December 31, 2017) are more varied, and policies are individually priced based on the risk characteristics of the policy and the account. The insured risks range from startup operations to large multinational entities and the larger entities often have significant deductibles or self-insured retentions. Reserves are established using our most recently developed actuarial estimates of losses expected to be incurred based on factors which include results from prior analysis of similar business, industry indications, observed trends and judgment. Claims in this line of business primarily involve bodily injury to individuals and are affected by factors similar to those of our HCPL line of business. For the medical technology liability business, we also establish an initial reserve using a loss ratio approach, including a provision in consideration of historical loss volatility that this line of business has exhibited.
Workers' Compensation Insurance Segment. Many factors affect the ultimate losses incurred for our workers' compensation coverages (10% of our consolidated gross reserve for losses and loss adjustment expenses as of December 31, 2017) including but not limited to the type and severity of the injury, the age and occupation of the injured worker, the estimated length of disability, medical treatment and related costs, and the jurisdiction and workers' compensation laws of the state of the injury occurrence. We use various actuarial methodologies in developing our workers’ compensation reserve, combined with a review of the exposure base generally based upon payroll of the insured. For the current accident year, given the lack of seasoned information, the different actuarial methodologies produce results with significant variability; therefore, more emphasis is placed on supplementing results from the actuarial methodologies with trends in exposure base, medical expense inflation, general inflation, severity, and claim counts, among other things, to select an expected loss ratio.
Segregated Portfolio Cell Reinsurance Segment. The factors that affect the ultimate losses incurred for the workers' compensation and healthcare professional liability coverages assumed by the SPCs at Eastern Re and Inova Re (4% of our consolidated gross reserve for losses and loss adjustment expenses as of December 31, 2017) are consistent with that of our Workers’ Compensation Insurance and Specialty P&C segments, respectively.
Lloyd's Syndicates Segment. Due to the relatively short history of Syndicate 1729 (January 1, 2014) we are influenced by historical claims experience of the Lloyd's market for similar risks in estimating the appropriate initial reserves for our Lloyd's Syndicates segment (4% of our consolidated gross reserve for losses and loss adjustment expenses as of December 31, 2017). We expect loss ratios to fluctuate from quarter to quarter as Syndicate 1729 writes more business and the book begins to mature. Loss ratios can also fluctuate due to the timing of earned premium adjustments. Such adjustments may be the result of premiums for certain policies and assumed reinsurance contracts being reported subsequent to the coverage period and may be subject to adjustment based on loss experience. Premium and exposure for some of Syndicate 1729's insurance policies and reinsurance contracts are initially estimated and subsequently recorded over an extended period of time as reports are received under delegated underwriting authority programs. When reports are received, the premium, exposure and corresponding loss estimates are revised accordingly. Changes in loss estimates due to premium or exposure fluctuations are incurred in the accident year in which the premium is earned.
For significant property catastrophe exposures, Syndicate 1729 uses third-party catastrophe models to accumulate a listing of potentially affected policies. Each identified policy is given an estimate of loss severity based upon a combination of factors including the probable maximum loss of each policy, market share analytics, underwriting judgment, client/broker estimates and historical loss trends for similar events. These models are inherently uncertain, reliant upon key assumptions and management judgment and are not always a representation of actual events and ensuing potential loss exposure. Determination of actual losses may take an extended period of time until claims are reported and resolved, including coverage litigation.
Syndicate 6131, which began active operations effective January 1, 2018, follows a process similar to Syndicate 1729 for the establishment of initial reserves. Loss assumptions by risk category incorporated into the 2018 business plan submitted to Lloyd's were influenced by historical claims experience of the Lloyd's market for similar risks. We expect the loss ratios of Syndicate 6131 to fluctuate from quarter to quarter as Syndicate 6131 assumes more business from Syndicate 1729 and the book begins to mature.

Development of Prior Accident Years
In addition to setting the initial reserve for the current accident year, each period we reassess the amount of reserve required for prior accident years.
The foundation of our reserve re-estimation process is an actuarial analysis based on our most recently available claims data and currently available industry trend information. Changes to previously established reserve estimates are recognized in the current period if management’s best estimate of ultimate losses differs from the estimate previously established. While management considers a variety of variables in determining its best estimate, in general, as claims age, our methodologies give more weight to actual loss costs which, for the majority of our reserves, continue to indicate that ultimate loss costs will be lower than our previous estimates. The discussion in our Critical Accounting Estimates section in Item 7 of our 2017 Form 10-K includes additional information regarding the methodologies used to evaluate our reserve.
Any change in our estimate of net ultimate losses for prior years is reflected in net income in the period in which such changes are made. In recent years such changes have reduced our estimate of net ultimate losses, resulting in a reduction of reported losses for the period and a corresponding increase in pre-tax income.
Due to the size of our consolidated reserve for losses and the large number of claims outstanding at any point in time, even a small percentage adjustment to our total reserve estimate could have a material effect on our results of operations for the period in which the adjustment is made.
Use of Judgment
Even though the actuarial process is highly technical, it is also highly judgmental, both as to the selection of the data used in the various actuarial methodologies (e.g., initial expected loss ratios and loss development factors) and in the interpretation of the output of the various methods used. Each actuarial method generally returns a different value and for the more recent accident years the variations among the various methodologies can be significant. For each partition of our reserves, we evaluate the results of the various methods, along with the supplementary statistical data regarding such factors as closed with and without indemnity ratios, claim severity trends, the expected duration of such trends, changes in the legal and legislative environment and the current economic environment to develop a point estimate based upon management's judgment and past experience. The series of selected point estimates is then combined to produce an overall point estimate for ultimate losses.
Given the potential for unanticipated volatility for long-tailed lines of business, we are cautious in giving full credibility to emerging trends that, when more fully mature, may lead to the recognition of either favorable or adverse development of our losses. There may be trends, both positive and negative, reflected in the numerical data both within our own information and in the broader marketplace that mitigate or reverse as time progresses and additional data becomes available. This is particularly true for our HCPL business which has historically exhibited significant volatility as previously discussed.
HCPL. Over the past several years the most influential factor affecting the analysis of our HCPL reserves and the related development recognized has been the change, or lack thereof, in the severity of claims. The severity trend is an explicit component of our pricing models, whereas in our reserving process the severity trend's impact is implicit. Our estimate of this trend and our expectations about changes in this trend impact a variety of factors, from the selection of expected loss ratios to the ultimate point estimates established by management.
Because of the implicit and wide-ranging nature of severity trend assumptions on the loss reserving process it is not practical to specifically isolate the impact of changing severity trends. However, because severity is an explicit component of our HCPL pricing process we can better isolate the impact that changing severity can have on our loss costs and loss ratios in regards to our pricing models for this business component. Our current HCPL pricing models assume a severity trend of approximately 3% in most states and products. We have observed potentially higher severity trends in our case reserve estimates but these have not been confirmed by actual claim payments. If the severity trend were to be higher by 1 percentage point, the impact would be an increase in our expected loss ratio for this business of 3.2 percentage points, based on current claim disposition patterns. An increase in the severity trend of 3 percentage points would result in a 10.1 percentage point increase in our expected loss ratio. Due to the long-tailed nature of our claims and the previously discussed historical volatility of loss costs, selection of a severity trend assumption is a subjective process that is inherently likely to prove inaccurate over time. Given the long tail and volatility, we are generally cautious in making changes to the severity assumptions within our pricing models. All open claims and accident years are generally impacted by a change in the severity trend, which compounds the effect of such a change.
Although the future degree and impact of the ultimate severity trend remains uncertain due to the long-tailed nature of our business, we have given consideration to observed loss costs in setting our rates. For our HCPL business this practice had generally resulted in rate reductions as claim frequency declined and remained at historically low levels. For example, on average, excluding our podiatry business acquired in 2009, we had gradually reduced the premium rates we charged on our standard physician renewal business (our largest HCPL line) by approximately 17% from the beginning of 2006 to December 31, 2016. However, from the beginning of 2017 to September 30, 2018, the average charged rates on our standard physician

48

Table of Contents

renewal business have increased by 4% and we anticipate further rate increases due to indications of increasing loss severity. Loss ratios for recent accident years have thus remained fairly constant because expected loss changes have been reflected in our rates; however, we have recognized a higher current accident year net loss ratio during 2018 due to those recent severity indications.
Workers' Compensation. The projection of changes in claim severity trend has not historically been an influential factor affecting our analysis of workers' compensation reserves, as claims are typically resolved more quickly than the industry norm. As previously mentioned, the determination and calculation of loss development factors, in particular, the selection of tail factors which are used to extend the projection of losses beyond historical data, requires considerable judgment.
Loss Development
We recognized net favorable reserve development of $21.5 million during the three months ended September 30, 2018, of which favorable development of $14.4 million related to our Specialty P&C segment, $2.8 million related to our Workers' Compensation Insurance segment, $3.7 million related to our Segregated Portfolio Cell Reinsurance segment and $0.6 million related to our Lloyd's Syndicates segment. We recognized net favorable development of $67.1 million during the nine months ended September 30, 2018, of which favorable development of $55.0 million related to our Specialty P&C segment, $4.2 million related to our Workers' Compensation Insurance segment and $8.2 million related to our Segregated Portfolio Cell Reinsurance segment, slightly offset by unfavorable development of $0.3 million related to our Lloyd's Syndicates segment.
Net favorable development recognized within our Specialty P&C segment was primarily attributable to the favorable resolution of HCPL claims during the period and an evaluation of established case reserves and paid claims data that indicated that the average severity trend associated with the remaining HCPL claims is less than we had previously estimated.
Net favorable development recognized within our Workers' Compensation Insurance segment reflected overall favorable trends in claim closing patterns primarily in the 2015 and 2016 accident years.
Net favorable development recognized within our Segregated Portfolio Cell Reinsurance segment primarily reflected better than expected claim trends in the 2015, 2016 and 2017 accident years. The improved claim trends reflected lower frequency and severity than anticipated at the time the reserves were established.
Net unfavorable development recognized within our Lloyd's Syndicates segment for the nine months ended September 30, 2018 was driven by higher than expected losses and development on certain large claims which resulted in unfavorable development with respect to a previous year of account. See further discussion in our Segment Operating Results - Lloyd's Syndicates section that follows.

Investment Valuations
We record the majority of our investments at fair value as shown in the table below. At September 30, 2018 the distribution of our investments based on GAAP fair value hierarchies (levels) was as follows:

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. All of our fixed maturity and equity investments are carried at fair value. The fair value of our short-term securities approximates the cost of the securities due to their short-term nature.
Because of the number of securities we own and the complexity of developing accurate fair values, we utilize multiple independent pricing services to assist us in establishing the fair value of individual securities. The pricing services provide fair values based on exchange-traded prices, if available. If an exchange-traded price is not available, the pricing services, if possible, provide a fair value that is based on multiple broker/dealer quotes or that has been developed using pricing models. Pricing models vary by asset class and utilize currently available market data for securities comparable to ours to estimate a fair value for our securities. The pricing services scrutinize market data for consistency with other relevant market information before including the data in the pricing models. The pricing services disclose the types of pricing models used and the inputs used for each asset class. Determining fair values using these pricing models requires the use of judgment to identify

49

Table of Contents

appropriate comparable securities and to choose a valuation methodology that is appropriate for the asset class and available data.
The pricing services provide a single value per instrument quoted. We review the values provided for reasonableness each quarter by comparing market yields generated by the supplied value versus market yields observed in the marketplace. We also compare yields indicated by the provided values to appropriate benchmark yields and review for values that are unchanged or that reflect an unanticipated variation as compared to prior period values. We utilize a primary pricing service for each security type and compare provided information for consistency with alternate pricing services, known market data and information from our own trades, considering both values and valuation trends. We also review weekly trades versus the prices supplied by the services. If a supplied value appears unreasonable, we discuss the valuation in question with the pricing service and make adjustments if deemed necessary. Historically our review has not resulted in any material changes to the values supplied by the pricing services. The pricing services do not provide a fair value unless an exchange-traded price or multiple observable inputs are available. As a result, the pricing services may provide a fair value for a security in some periods but not others, depending upon the level of recent market activity for the security or comparable securities.
Level 1 Investments
Fair values for a majority of our equity securities and portions of our corporate debt, short-term and convertible securities are determined using exchange-traded prices. There is little judgment involved when fair value is determined using an exchange-traded price. In accordance with GAAP, for disclosure purposes we classify securities valued using an exchange-traded price as Level 1 securities.
Level 2 Investments
Most fixed income securities do not trade daily; and thus, exchange-traded prices are generally not available for these securities. However, market information (often referred to as observable inputs or market data, including but not limited to, last reported trade, non-binding broker quotes, bids, benchmark yield curves, issuer spreads, two-sided markets, benchmark securities, offers and recent data regarding assumed prepayment speeds, cash flow and loan performance data) is available for most of our fixed income securities. We determine fair value for a large portion of our fixed income securities using available market information. In accordance with GAAP, for disclosure purposes we classify securities valued based on multiple market observable inputs as Level 2 securities.
Level 3 Investments
When a pricing service does not provide a value for one of our fixed maturity securities, management estimates fair value using either a single non-binding broker quote or pricing models that utilize market based assumptions which have limited observable inputs. The process involves significant judgment in selecting the appropriate data and modeling techniques to use in the valuation process. For disclosure purposes, we classify securities valued using limited observable inputs as Level 3 securities.
Fair Values Not Categorized
We hold interests in certain investment funds, primarily LPs/LLCs, which measure fund assets at fair value on a recurring basis and provide us with a NAV for our interest. As a practical expedient, we consider the NAV provided to approximate the fair value of the interest. In accordance with GAAP, for disclosure purposes we do not categorize these investments within the fair value hierarchy.
Nonrecurring Fair Value Measurements
We measure the fair value of certain assets on a nonrecurring basis when events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. These assets include investments carried principally at cost, investments in tax credit partnerships and equity method investments that do not provide a NAV, fixed assets, goodwill and other intangible assets.

Other-than-temporary Impairments
We evaluate our available-for-sale investment securities on at least a quarterly basis for the purpose of determining whether declines in fair value below recorded cost basis represent OTTI. We consider an OTTI to have occurred:
if there is intent to sell the security;
if it is more likely than not that the security will be required to be sold before full recovery of its amortized cost basis; or
if the entire amortized basis of the security is not expected to be recovered.
The assessment of whether the amortized cost basis of a security, particularly an asset-backed debt security, is expected to be recovered requires management to make assumptions regarding various matters affecting future cash flows. The choice of assumptions is subjective and requires the use of judgment. Actual credit losses experienced in future periods may differ from management’s estimates of those credit losses. Methodologies used to estimate the present value of expected cash flows are:
For non-structured fixed maturities (obligations of states, municipalities and political subdivisions and corporate debt) the estimate of expected cash flows is determined by projecting a recovery value and a recovery time frame and assessing whether further principal and interest will be received. We consider various factors in projecting recovery values and recovery time frames, including the following:
third-party research and credit rating reports;
the current credit standing of the issuer, including credit rating downgrades, whether before or after the balance sheet date;
the extent to which the decline in fair value is attributable to credit risk specifically associated with the security or its issuer;
internal assessments and the assessments of external portfolio managers regarding specific circumstances surrounding an investment, which indicate the investment is more or less likely to recover its amortized cost than other investments with a similar structure;
for asset-backed securities, the origination date of the underlying loans, the remaining average life, the probability that credit performance of the underlying loans will deteriorate in the future, and our assessment of the quality of the collateral underlying the loan;
failure of the issuer of the security to make scheduled interest or principal payments;
any changes to the rating of the security by a rating agency; and
recoveries or additional declines in fair value subsequent to the balance sheet date.
For structured securities (primarily asset-backed securities), management estimates the present value of the security’s cash flows using the effective yield of the security at the date of acquisition (or the most recent implied rate used to accrete the security if the implied rate has changed as a result of a previous impairment or changes in expected cash flows). We consider the most recently available six month averages of the levels of delinquencies, defaults, severities, and prepayments for the collateral (loans) underlying the securitization or, if historical data is not available, sector based assumptions, to estimate expected future cash flows of these securities.
Exclusive of securities where there is an intent to sell or where it is not more likely than not that the security will be required to be sold before recovery of its amortized cost basis, OTTI for debt securities is separated into a credit component

51

Table of Contents

and a non-credit component. The credit component of an OTTI is the difference between the security’s amortized cost basis and the present value of its expected future cash flows, while the non-credit component is the remaining difference between the security’s fair value and the present value of expected future cash flows. The credit component of the OTTI is recognized in earnings while the non-credit component is recognized in OCI.
Investments in tax credit partnerships are evaluated for OTTI by considering both qualitative and quantitative factors. These factors include, but are not limited to:
our ability and intent to hold the investment until the recovery of its carrying value; and
in situations where there was not a previous OTTI for the investment, whether the current expected cash flows from the investment, primarily tax benefits, are less than those expected at the time the investment was acquired due to various factors, such as a change in the statutory tax rate; or
in situations where there was a previous OTTI for the investment, whether the expected cash flows from the investment at the time of the OTTI, primarily tax benefits, are less than its current carrying value.
Investments which are accounted for under the equity method are evaluated for impairment whenever events or changes in circumstances indicate that the carrying value of the investment might not be recoverable. These circumstances include, but are not limited to, evidence of the inability to recover the carrying value of the investment, the inability of the investee to sustain an earnings capacity that would justify the carrying value of the investment or the current fair value of the investment that is less than the carrying value.
We recognize OTTI, exclusive of non-credit OTTI, in earnings as a part of net realized investment gains (losses). In subsequent periods, any measurement of gain, loss or impairment is based on the revised amortized basis of the security. Non-credit OTTI on debt securities and declines in fair value of available-for-sale securities not considered to be other-than-temporary are recognized in OCI.
Asset-backed debt securities that have been impaired due to credit reasons or are below investment grade quality are accounted for under the effective yield method. Under the effective yield method, estimates of cash flows expected over the life of asset-backed securities are used to recognize income on the investment balance for subsequent accounting periods.
Deferred Policy Acquisition Costs
Policy acquisition costs (primarily commissions, premium taxes and underwriting salaries) which are directly related to the successful acquisition of new and renewal premiums are capitalized as DPAC and charged to expense, net of ceding commissions earned, as the related premium revenue is recognized. We evaluate the recoverability of our DPAC at the segment level each reporting period, and any amounts estimated to be unrecoverable are charged to expense in the current period. As of September 30, 2018 we have not determined that any amounts are unrecoverable.
Estimation of Taxes / Tax Credits
For interim periods, we determine our provision (benefit) for income taxes based on the current estimate of our annual effective tax rate. Items which are unusual, infrequent, or that cannot be reliably estimated are considered in the effective tax rate in the period in which the item is included in income, and are referred to as discrete items. In calculating our estimated annual effective tax rate, we include the estimated benefit of tax credits for the annual period based on the most recently available information provided by the tax credit partnerships; the actual amounts of credits provided by the tax credit partnerships may prove to be different than our estimates. The effect of such a difference is recognized in the period identified.
Deferred Taxes
Deferred federal income taxes arise from the recognition of temporary differences between the basis of assets and liabilities determined for financial reporting purposes and the basis determined for income tax purposes. Our temporary differences principally relate to our loss reserve, unearned premiums, DPAC, unrealized investment gains (losses) and basis differences on fixed assets and investment assets. Deferred tax assets and liabilities are measured using the enacted tax rates expected to be in effect when such benefits are realized. We review our deferred tax assets quarterly for impairment. If we determine that it is more likely than not that some or all of a deferred tax asset will not be realized, a valuation allowance is recorded to reduce the carrying value of the asset. In assessing the need for a valuation allowance, management is required to make certain judgments and assumptions about our future operations based on historical experience and information as of the measurement period regarding reversal of existing temporary differences, carryback capacity, future taxable income (including its capital and operating characteristics) and tax planning strategies.

A valuation allowance has been established against the full value of the deferred tax asset related to the NOL carryforwards for the U.K. operations as management concluded that it was more likely than not that the deferred tax asset will not be realized. See further discussion in Note 5 of the Notes to Consolidated Financial Statements in our December 31, 2017 Form 10-K.
Tax Cuts and Jobs Act
The TCJA was signed into law on December 22, 2017 and contains several key provisions that impact our business, including the reduction of the corporate tax rate to 21% effective January 1, 2018, the reduction in the amount of executive compensation that could qualify as a tax deduction, a minimum tax on payments made to related foreign entities and a change in how property and casualty taxpayers discount loss reserves. See Note 5 of the Notes to Condensed Consolidated Financial Statements for discussion of the current status of our accounting for certain provisions of the TCJA.
Effective January 1, 2018, the TCJA introduced a minimum tax on payments made to related foreign entities referred to as the BEAT. The BEAT is imposed by adding back into the U.S. tax base any base erosion payment made by the U.S. taxpayer to a related foreign entity and applying a minimum tax rate to this newly calculated modified taxable income. Base erosion payments represent any amount paid or accrued by the U.S. taxpayer to a related foreign entity for which a deduction is allowed. Premiums we cede to the SPCs at our newly formed wholly owned Cayman Islands reinsurance subsidiary, Inova Re, do not fall within the scope of base erosion payments as the SPCs at Inova Re intend to elect to be taxed as U.S. taxpayers. However, premiums that we cede to any active SPC at our other wholly owned Cayman Islands reinsurance subsidiary, Eastern Re, fall within the scope of base erosion payments and therefore could be significantly impacted by the BEAT. We have evaluated our exposure to the BEAT and have concluded that our expected outbound deductible payments to related foreign entities are below the threshold for application of the BEAT; therefore, we have not recognized any incremental tax expense for the BEAT provision of the TCJA for the three and nine months ended September 30, 2018. See further discussion on our new subsidiary, Inova Re, and our Cayman Islands SPC operations in the Segment Operating Results - Segregated Portfolio Cell Reinsurance section that follows.
Unrecognized Tax Benefits
We evaluate tax positions taken on tax returns and recognize positions in our financial statements when it is more likely than not that we will sustain the position upon resolution with a taxing authority. If recognized, the benefit is measured as the largest amount of benefit that has a greater than 50% probability of being realized. We review uncertain tax positions each period, considering changes in facts and circumstances, such as changes in tax law, interactions with taxing authorities and developments in case law, and make adjustments as we consider necessary. Adjustments to our unrecognized tax benefits may affect our income tax expense, and settlement of uncertain tax positions may require the use of cash. Other than differences related to timing, no significant adjustments were considered necessary during the three and nine months ended September 30, 2018 or 2017. At September 30, 2018, our liability for unrecognized tax benefits approximated $4.5 million.
Goodwill
We evaluate goodwill for impairment annually on October 1 and upon the occurrence of certain triggering events or substantive changes in circumstances that indicate the fair value of goodwill may be impaired. Impairment of goodwill is tested at the reporting unit level, which is consistent with our reportable segments identified in Note 13 of the Notes to Condensed Consolidated Financial Statements.
As discussed in Note 13 of the Notes to Condensed Consolidated Financial Statements, we reorganized our segment reporting in the third quarter of 2018 to align with how our CODM currently oversees the business, allocates resources and evaluates operating performance. As a result of the segment reorganization, we added an operating and reportable segment: Segregated Portfolio Cell Reinsurance. The Segregated Portfolio Cell Reinsurance segment also became a reporting unit for purposes of testing goodwill impairment. We allocated goodwill to our revised reporting units using a relative fair value approach which resulted in a nominal amount of goodwill reallocated from the Workers' Compensation Insurance reporting unit to the Segregated Portfolio Cell Reinsurance reporting unit. We estimated the fair value of the reporting units using both an income approach and market approach. The estimate of fair value derived from the income approach is based on the present value of expected future cash flows, including terminal value, utilizing a market-based weighted average cost of capital determined separately for each reporting unit. The estimate of fair value derived from the market approach is based on earnings multiple data. The determination of fair value involves the use of significant estimates and assumptions, including revenue growth rates, operating margins, capital expenditures, working capital requirements, tax rates, terminal growth rates, discount rates, comparable public companies and synergistic benefits available to market participants. In addition, we make certain judgments and assumptions in allocating shared assets and liabilities to individual reporting units to determine the carrying amount of each reporting unit. To corroborate the reporting units’ valuation, we performed a reconciliation of the estimate of the aggregate fair value of the reporting units to ProAssurance's market capitalization, including consideration of a control

premium. Additionally, we performed a quantitative goodwill impairment assessment for the Workers' Compensation Insurance reporting unit immediately prior to the reallocation and a quantitative goodwill impairment assessment for the Workers' Compensation Insurance and Segregated Portfolio Cell Reinsurance reporting units immediately after the reallocation and determined that no impairment existed.
The Specialty P&C reporting unit is the only other remaining reporting unit that has goodwill; the Specialty P&C reporting unit's net operating results were not impacted by the segment reorganization and there was no change to the amount of goodwill allocated to that reporting unit. Consistent with our accounting policy described in Note 1 of the Notes to Consolidated Financial Statements included in ProAssurance's December 31, 2017 Form 10-K, we will evaluate goodwill for impairment on October 1 under the new reporting unit structure.
Intangibles
Intangible assets with definite lives are amortized over the estimated useful life of the asset. Amortizable intangible assets primarily consist of agency and policyholder relationships, renewal rights and trade names. Intangible assets with an indefinite life, primarily state licenses, are not amortized. Intangible assets are evaluated for impairment on an annual basis. The third quarter 2018 segment reorganization had no impact on how we evaluate our intangible assets for impairment. Additional information regarding intangible assets is included in Note 1 of the Notes to Consolidated Financial Statements included in ProAssurance's December 31, 2017 Form 10-K.
Audit Premium
Workers’ compensation premiums are determined based upon the payroll of the insured, applicable premium rates and an experience-based modification factor, where applicable. An audit of the policyholders’ records is conducted after policy expiration to make a final determination of applicable premiums. Audit premium due from or due to a policyholder as a result of an audit is reflected in net premiums written and earned when billed. We track, by policy, the amount of additional premium billed in final audit invoices as a percentage of payroll exposure and use this information to estimate the probable additional amount of EBUB premium as of the balance sheet date. We include changes to the EBUB premium estimate in net premiums written and earned in the period recognized.
Lloyd’s Premium Estimates
For certain insurance policies and reinsurance contracts written in our Lloyd’s Syndicates segment, premiums are initially recognized based upon estimates of ultimate premium. Estimated ultimate premium consists primarily of premium written under delegated underwriting authority arrangements, which consist primarily of binding authorities, and certain assumed reinsurance agreements. These estimates of ultimate premium are judgmental and are dependent upon certain assumptions, including historical premium trends for similar agreements. As reports are received from programs, ultimate premium estimates are revised, if necessary, with changes reflected in current operations.
Accounting Changes
We did not adopt any accounting changes or have any change in accounting estimate or policy that had a material effect on our results of operations or financial position during the nine months ended September 30, 2018. We are not aware of any accounting changes not yet adopted as of September 30, 2018 that would have a material effect on our results of operations or financial position.

Liquidity and Capital Resources and Financial Condition
Overview
ProAssurance Corporation is a holding company and is a legal entity separate and distinct from its subsidiaries. As a holding company our principal source of external revenue is our investment revenues. In addition, dividends from our operating subsidiaries represent a significant source of funds for our obligations, including debt service and shareholder dividends. We also charge our operating subsidiaries within our Specialty P&C and Workers' Compensation Insurance segments a management fee based on the extent to which services are provided to the subsidiary and the amount of premium written by the subsidiary. At September 30, 2018, we held cash and liquid investments of approximately $214 million outside our insurance subsidiaries that were available for use without regulatory approval or other restriction. We also have $200 million in permitted borrowings under our Revolving Credit Agreement and an accordion feature available which, if subscribed successfully, would allow another $50 million in available funds. As of October 31, 2018, no borrowings were outstanding under our Revolving Credit Agreement.
To date, during 2018, our operating subsidiaries have paid dividends to us of approximately $178 million, which included $73 million that was paid in October 2018. Of the total dividends paid, $48 million were extraordinary dividends. Dividends paid in October 2018 have not been included in our cash and liquid investments held outside of our insurance subsidiaries at September 30, 2018. Our insurance subsidiaries, in the aggregate, do not intend to pay additional dividends over the remainder of 2018. The payment of any dividend requires prior notice to the insurance regulator in the state of domicile, and the regulator may reduce or prevent the dividend if, in its judgment, payment of the dividend would have an adverse effect on the surplus of the insurance subsidiary. We make the decision to pay dividends from an insurance subsidiary based on the capital needs of that subsidiary, and may pay less than the permitted dividend or may also request permission to pay an additional amount (an extraordinary dividend).

During the first quarter of 2018, we retrospectively adopted accounting guidance that resulted in a change in classification of distributions received from unconsolidated subsidiaries. Additional information regarding the impact of accounting guidance adopted during the current period can be found in Note 1 to the Notes to Condensed Consolidated Financial Statements.
The principal components of our operating cash flows are the excess of premiums collected and net investment income over losses paid and operating costs, including income taxes. Timing delays exist between the collection of premiums and the payment of losses associated with the premiums. Premiums are generally collected within the twelve-month period after the policy is written, while our claim payments are generally paid over a more extended period of time. Likewise, timing delays exist between the payment of claims and the collection of any associated reinsurance recoveries.
The increase in operating cash flows for the nine months ended September 30, 2018 as compared to the nine months ended September 30, 2017 of $28.2 million was primarily due to an increase in premium receipts of $52.9 million and a decrease in 2018 estimated tax payments as compared to 2017 of $9.9 million, partially offset by an increase in paid losses of

55

Table of Contents

$28.6 million, an increase in cash paid for operating expenses of $5.4 million and a decrease in cash received from investment income of $2.6 million. The increase in premium receipts was driven by our Specialty P&C segment, primarily due to premium received from a loss portfolio transfer entered into during the second quarter of 2018 and, to a lesser extent, our Workers' Compensation Insurance segment, primarily due to premiums received related to the third quarter 2017 acquisition of the Great Falls book of business. The increase in paid losses was driven by all of our operating segments, particularly in our Lloyd's Syndicates segment, primarily due to storm-related losses related to 2017 Hurricanes Harvey, Irma and Maria, and our Specialty P&C segment. The increase in cash paid for operating expenses was primarily due to an increase in compensation related costs and commission expenses and the decrease in cash received from investment income was primarily due to a reduction in dividends received on our fixed maturities portfolio resulting from lower average balances.
The decrease in operating cash flows for the nine months ended September 30, 2017 as compared to the nine months ended September 30, 2016 of $14.3 million was primarily driven by an increase in tax payments of $27.1 million due to the effect of a $15.0 million tax refund received in 2016 for the 2015 tax year and a $12.1 million increase in 2017 estimated tax payments as compared to 2016. These decreases in operating cash flows were partially offset by an increase in cash received from investment income of $8.9 million and an increase in premium receipts of $5.1 million driven by our Workers' Compensation Insurance segment.
We manage our investing cash flows to ensure that we will have sufficient liquidity to meet our obligations, taking into consideration the timing of cash flows from our investments, including interest payments, dividends and principal payments, as well as the expected cash flows to be generated by our operations as discussed in this section under the heading "Investing Activities and Related Cash Flows."
Our financing cash flows are primarily composed of dividend payments and borrowings and repayments under our Revolving Credit Agreement. See further discussion of our financing activities in this section under "Financing Activities and Related Cash Flows."
Operating Activities and Related Cash Flows
Reinsurance
Within our Specialty P&C segment, we use insurance and reinsurance (collectively, “reinsurance”) to provide capacity to write larger limits of liability, to provide reimbursement for losses incurred under the higher limit coverages we offer and to provide protection against losses in excess of policy limits. Within our Workers' Compensation Insurance segment, we use reinsurance to reduce our net liability on individual risks, to mitigate the effect of significant loss occurrences (including catastrophic events), to stabilize underwriting results, and to increase underwriting capacity by decreasing leverage. In both our Specialty P&C and Workers' Compensation Insurance segments, we use reinsurance in risk sharing arrangements to align our objectives with those of our strategic business partners and to provide custom insurance solutions for large customer groups. The purchase of reinsurance does not relieve us from the ultimate risk on our policies; however, it does provide reimbursement for certain losses we pay. We pay our reinsurers a premium in exchange for reinsurance of the risk. In the majority of our excess of loss arrangements, the premium due to the reinsurer is determined by the loss experience of the business reinsured, subject to certain minimum and maximum amounts. Until all loss amounts are known, we estimate the premium due to the reinsurer. Changes to the estimate of premium owed under reinsurance agreements related to prior periods are recorded in the period in which the change in estimate occurs and can have a significant effect on net premiums earned.
We offer alternative market solutions whereby we cede certain premiums from our Workers' Compensation Insurance and Specialty P&C segments to either the SPCs at Eastern Re or Inova Re, our Cayman Islands reinsurance subsidiaries which are reported in our Segregated Portfolio Cell Reinsurance segment, or, to a limited extent, unaffiliated captive insurers. During the three and nine months ended September 30, 2018, we wrote workers' compensation and healthcare professional liability policies in our alternative market business generating premium of approximately $17.3 million and $72.5 million, respectively. The majority of these policies ($16.8 million and $68.3 million of premium for the three and nine months ended September 30, 2018, respectively) are reinsured to the SPCs of our wholly owned subsidiaries, Eastern Re and Inova Re, domiciled in the Cayman Islands, net of a ceding commission, which are reported in our Segregated Portfolio Cell Reinsurance segment. See further discussion on our SPC operations at Eastern Re and Inova Re in the Segment Operating Results - Segregated Portfolio Cell Reinsurance section that follows. The alternative market workers' compensation policies are ceded from our Workers' Compensation Insurance segment to the SPCs under 100% quota share reinsurance agreements. The alternative market professional liability policies are ceded from our Specialty P&C segment to the SPCs under either excess of loss or quota share reinsurance agreements, depending on the structure of the individual program, and the portion of the risk that is not ceded to an SPC may also be reinsured under our standard healthcare professional liability reinsurance program depending on the policy limits provided. The remaining premium written in our alternative market business of $0.5 million and $4.3 million for the three and nine months ended September 30, 2018, respectively, is 100% ceded to unaffiliated captive insurers.

Prior to January 1, 2018, Syndicate 1729 served as a reinsurer on a quota share basis for a wholly owned insurance subsidiary in our Specialty P&C segment. Syndicate 1729 did not renew the quota share agreement with our Specialty P&C segment on January 1, 2018.
For all of our segments, we make a determination of the amount of insurance risk we choose to retain based upon numerous factors, including our risk tolerance and the capital we have to support it, the price and availability of reinsurance, the volume of business, our level of experience with a particular set of claims and our analysis of the potential underwriting results. We purchase excess of loss reinsurance to limit the amount of risk we retain and we do so from a number of companies to mitigate concentrations of credit risk. We utilize reinsurance brokers to assist us in the placement of these reinsurance programs and in the analysis of the credit quality of our reinsurers. The determination of which reinsurers we choose to do business with is based upon an evaluation of their then current financial strength, rating and stability. However, the financial strength of our reinsurers and their corresponding ability to pay us may change in the future due to forces or events we cannot control or anticipate.
Excess of Loss Reinsurance Agreements
We generally reinsure risks under treaties (our excess of loss reinsurance agreements) pursuant to which the reinsurers agree to assume all or a portion of all risks that we insure above our individual risk retention levels, up to the maximum individual limits offered. These agreements are negotiated and renewed annually. Renewal dates for our healthcare professional liability, medical technology liability and workers' compensation treaties are October 1, January 1 and May 1, respectively. There were no significant changes in the cost or structure of our professional liability and medical technology liability treaties which renewed October 1, 2018 and January 1, 2018, respectively. Our workers' compensation treaty renewed May 1, 2018 at a higher rate than the previous agreement. The significant coverages provided by our current excess of loss reinsurance agreements are detailed in the following table.

(1) Historically, retention has ranged from 5% to 32.5%.
(2) Historically, retention has been as high as $2M.

Large professional liability risks that are above the limits of our basic reinsurance treaties are reinsured on a facultative basis, whereby the reinsurer agrees to insure a particular risk up to a designated limit. We also have in place a number of risk sharing arrangements that apply to the first $1 million of losses for certain large healthcare systems and other insurance entities and with certain insurance agencies that produce business for us.
Other Reinsurance Arrangements
For the workers' compensation business ceded to Eastern Re and Inova Re, each SPC has in place its own reinsurance arrangements; which are illustrated in the following table.
Segregated Portfolio Cell Reinsurance

Per Occurrence Coverage
 
Aggregate Coverage (1)
(1) Prior to May 1, 2018, ProAssurance assumed 100% of aggregate losses in excess of an aggregate attachment point with a maximum loss limit of $100K. Effective May 1, 2018, ProAssurance no longer participates in the aggregate reinsurance coverage.
(2) The attachment point is based on a percentage of written premium (average is 89%) and varies by cell.
Each SPC has preferred shareholders or participants and the operating profit or loss of each SPC accrues fully to these preferred shareholders or participants. We participate in certain SPCs and as of September 30, 2018, our ownership interest in the SPCs in which we participate is as low as 25% and as high as 85%. Each SPC maintains a loss fund initially equal to the difference between premium assumed by the cell and the ceding commission. The external owners of each cell provide a letter of credit to us that is initially equal to the difference between the loss fund of the SPC (amount of funds available to pay losses after deduction of ceding commission) and the aggregate attachment point of the reinsurance. Over time, a SPC's retained profits are considered in the determination of the collateral amount required to be provided by the cell's external owners.

Within our Lloyd's Syndicates segment, Syndicate 1729 utilizes reinsurance to provide capacity to write larger limits of liability on individual risks, to provide protection against catastrophic loss and to provide protection against losses in excess of policy limits. The level of reinsurance that Syndicate 1729 purchases is dependent on a number of factors, including its underwriting risk appetite for catastrophic exposure, the specific risks inherent in each line or class of business written and the pricing, coverage and terms and conditions available from the reinsurance market. Reinsurance protection by line of business is as follows:
Reinsurance is utilized on a per risk basis for the property insurance and casualty coverages in order to mitigate risk volatility.
Catastrophic protection is utilized on both our property insurance and casualty coverages to protect against losses in excess of policy limits as well as natural catastrophes.
Both quota share reinsurance and excess of loss reinsurance are utilized to manage the net loss exposure on our property reinsurance coverages.
Property umbrella excess of loss reinsurance is utilized for peak catastrophe and frequency of catastrophe exposures.
Beginning in 2018, external excess of loss reinsurance is utilized by Syndicate 1729 to manage the net loss exposure on the specialty property and contingency coverages ceded to Syndicate 6131 (see further discussion in Segment Operating Results - Lloyd's Syndicates section that follows).
Syndicate 1729 may still be exposed to losses that exceed the level of reinsurance purchased as well as to reinstatement premiums triggered by losses exceeding specified levels. Cash demands on Syndicate 1729 can vary significantly depending on the nature and intensity of a loss event. For significant reinsured catastrophe losses, the inability or unwillingness of the reinsurer to make timely payments under the terms of the reinsurance agreement could have an adverse effect on Syndicate 1729's liquidity.
Litigation
We are involved in various legal actions related to insurance policies and claims handling including, but not limited to, claims asserted against us by policyholders. These types of legal actions arise in the ordinary course of business and, in accordance with GAAP for insurance entities, are generally considered as a part of our loss reserving process, which is described in detail in our Critical Accounting Estimates section under the heading "Reserve for Losses and Loss Adjustment Expenses." We also have other direct actions against the Company unrelated to our claims activity which we evaluate and account for as a part of our other liabilities. For these corporate legal actions, we evaluate each case separately and establish what we believe is an appropriate reserve based on GAAP guidance related to contingent liabilities. As of September 30, 2018 there were no material reserves established for corporate legal actions.
Taxes
We are subject to the tax laws and regulations of the U.S. and U.K. We file a consolidated U.S. federal income tax return that includes the holding company and its U.S. subsidiaries. Our filing obligations include a requirement to make quarterly payments of estimated taxes to the IRS using the corporate tax rate effective for the tax year. As a result of the TCJA that was signed into law at the end of 2017, the corporate tax rate effective for the 2018 tax year is 21% as compared to 35% for the 2017 tax year. The lower corporate tax rate had no material effect on our liquidity for the nine months ended September 30, 2018.

A detailed listing of our investment holdings as of September 30, 2018 is located under the Financial Information heading on the Investor Relations page of our website which can be reached directly at www.proassurance.com/investmentholdings, or through links from the Investor Relations section of our website, investor.proassurance.com.
We manage our investments to ensure that we will have sufficient liquidity to meet our obligations, taking into consideration the timing of cash flows from our investments, including interest payments, dividends and principal payments, as well as the expected cash flows to be generated by our operations. In addition to the interest and dividends we will receive, we anticipate that between $40 million and $80 million of our investments will mature (or be paid down) each quarter over the next twelve months and become available, if needed, to meet our cash flow requirements. The primary outflow of cash at our insurance subsidiaries is related to paid losses and operating costs, including income taxes. The payment of individual claims cannot be predicted with certainty; therefore, we rely upon the history of paid claims in estimating the timing of future claims payments. To the extent that we may have an unanticipated shortfall in cash, we may either liquidate securities or borrow funds under existing borrowing arrangements through our Revolving Credit Agreement and the FHLB system. As of October 31, 2018, $250 million could be made available for use through our Revolving Credit Agreement, as discussed in this section under the heading "Debt." Given the duration of our investments, we do not foresee a shortfall that would require us to meet operating cash needs through additional borrowings. Additional information regarding the Revolving Credit Agreement is detailed in Note 8 of the Notes to Condensed Consolidated Financial Statements.
As discussed in Note 3 of the Notes to Condensed Consolidated Financial Statements, our fixed maturity and short-term investments include securities deposited with Lloyd's in order to meet our FAL requirement. At September 30, 2018, securities on deposit with Lloyd's included fixed maturities having a fair value of $124.7 million and short-term investments with a fair value of $0.7 million.
Our investment portfolio continues to be primarily composed of high quality fixed income securities with approximately 94% of our fixed maturities being investment grade securities as determined by national rating agencies. The weighted average effective duration of our fixed maturity securities at September 30, 2018 was 3.18 years; the weighted average effective duration of our fixed maturity securities combined with our short-term securities was 2.90 years.
The carrying value and unfunded commitments for certain of our investments were as follows:

(1) The carrying value reflects our total commitments (both funded and unfunded) to the partnerships, less any amortization, since our initial investment. We fund these investments based on funding schedules maintained by the partnerships.
(2) The carrying value reflects our funded commitments less any amortization.
Investment fund LPs/LLCs are by nature less liquid and may involve more risk than other investments. We manage our risk through diversification of asset class and geographic location. At September 30, 2018, we had investments in 35 separate investment funds with a total carrying value, as shown in the table above, which represented approximately 9% of our total investments. We review and monitor the performance of these investments on a quarterly basis.

Financing Activities and Related Cash Flows
Treasury Shares
During the nine months ended September 30, 2018 and 2017, we did not repurchase any common shares and, as of October 31, 2018, our remaining Board authorization was approximately $109.6 million.
ProAssurance Shareholder Dividends
Our Board declared quarterly cash dividends of $0.31 per share during each of the first three quarters of both 2018 and 2017, each of which was paid in the following quarter. Dividends paid in the first nine months of both 2018 and 2017 included a special dividend of $4.69 per share, declared in the fourth quarter of each of the previous years. Any decision to pay future cash dividends is subject to the Board’s final determination after a comprehensive review of financial performance, future expectations and other factors deemed relevant by the Board.
Debt
At September 30, 2018 our debt included $250 million of outstanding unsecured senior notes. The notes bear interest at 5.3% annually and are due in 2023 although they may be redeemed in whole or part prior to maturity. There are no financial covenants associated with these notes.
We have a Revolving Credit Agreement which may be used for general corporate purposes, including, but not limited to, short-term working capital, share repurchases as authorized by the Board and support for other activities. Our Revolving Credit Agreement permits borrowings of up to $200 million, and has available a $50 million accordion feature, which, if successfully subscribed, would expand permitted borrowings up to $250 million. At September 30, 2018, there were no outstanding borrowings on our Revolving Credit Agreement and we are in compliance with the financial covenants of the Revolving Credit Agreement, which expires in June 2020.
During 2017, two of our subsidiaries each entered into ten-year mortgage loans collectively totaling approximately $40 million (Mortgage Loans) with one lender in connection with the recapitalization of two office buildings. The Mortgage Loans accrue interest at three-month LIBOR plus 1.325% with principal and interest payable on a quarterly basis. At September 30, 2018, the outstanding balance of the Mortgage Loans was $39 million and we are in compliance with the financial covenant of the Mortgage Loans, which mature in December 2027.
Additional information regarding our debt is provided in Note 8 of the Notes to Condensed Consolidated Financial Statements.
During 2017, we entered into an interest rate cap agreement with a notional amount of $35 million to manage our exposure to increases in LIBOR on our Mortgage Loans. Per the interest rate cap agreement, we are entitled to receive cash payments if and when the three-month LIBOR exceeds 2.35%. Additional information on our interest rate cap agreement is provided in Note 9 of the Notes to Condensed Consolidated Financial Statements.
Two of our insurance subsidiaries are members of an FHLB. Through membership, those subsidiaries have access to secured cash advances which can be used for liquidity purposes or other operational needs. In order for us to use FHLB proceeds, regulatory approvals may be required depending on the nature of the transaction. To date, those subsidiaries have not materially utilized their membership for borrowing purposes.
Off-Balance Sheet Arrangements
We have no significant off-balance sheet arrangements that have or are reasonably likely to have a material current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources. See more information on our off-balance sheet arrangements in Note 7 of the Notes to Condensed Consolidated Financial Statements.

Executive Summary of Operations
As previously discussed under the heading "ProAssurance Overview," we reorganized our segment reporting in the third quarter of 2018 to include a new segment: Segregated Portfolio Cell Reinsurance. The Segregated Portfolio Cell Reinsurance segment reflects the operating results (underwriting profit or loss, plus investment results) of SPCs which assume workers’ compensation, healthcare professional liability or a combination of the two from our Workers' Compensation Insurance and Specialty P&C segments. The underwriting results of the SPCs that assume workers’ compensation business and healthcare professional liability business were previously reported in our Workers’ Compensation and Specialty P&C segments, respectively, and the results of investment assets solely allocated to SPC operations were previously reported in our Corporate segment, are now reported in the Segregated Portfolio Cell Reinsurance segment. The Workers' Compensation segment has also been renamed "Workers' Compensation Insurance." All prior period segment information has been recast to conform to the current period presentation and the segment reorganization had no impact on previously reported consolidated financial results. See further information regarding the segment reorganization in Note 13 of the Notes to Condensed Consolidated Financial Statements.
The following sections provide an overview of our consolidated and segment results of operations for the three and nine months ended September 30, 2018 as compared to the three and nine months ended September 30, 2017. See the Segment Operating Results sections that follow for additional information regarding each segment's operating results.

All of our operating segments contributed to the increase in net premiums earned during the three and nine months ended September 30, 2018 as compared to the same respective periods of 2017. The largest component of the increase in consolidated net premiums earned in the 2018 nine-month period was the $26.6 million of premium written and fully earned from a loss portfolio transfer entered into during the second quarter of 2018 in our Specialty P&C segment (see further discussion in our Segment Operating Results - Specialty Property & Casualty section that follows).

The increase in our consolidated net investment result for the three and nine months ended September 30, 2018 was primarily attributable to an increase in earnings from our unconsolidated subsidiaries, partially offset by a decrease in net investment income due to reduced earnings from our fixed income portfolio, which reflected lower average investment balances. The increase in earnings from our unconsolidated subsidiaries for the three and nine months ended September 30, 2018 primarily reflected the impact of the adoption of an accounting standard during the first quarter of 2018 around the recognition and measurement of financial assets and financial liabilities (see Note 1 of the Notes to Condensed Consolidated Financial Statements for additional detail regarding accounting changes adopted during the period). Under the new accounting standard, LPs/LLCs previously reported using the cost method are now reported at fair value with changes in fair value recognized as a component of equity in earnings (loss) of unconsolidated subsidiaries. Excluding the effect of the adoption of the new accounting standard, the investment results from our portfolio of investments in LPs/LLCs for the 2018 three- and nine-month periods decreased primarily due to lower reported earnings from a few LP investments.

The decrease in our consolidated current accident year net loss ratio in the 2018 three-month period was primarily due to the effect of storm-related losses recognized in the third quarter of 2017 in our Lloyd's Syndicates segment, partially offset by a higher current accident year net loss ratio in our Specialty P&C segment due to both changes in premium on loss sensitive policies and an increase in expected losses in our excess and surplus lines business.
The slight increase in our consolidated current accident year net loss ratio in the 2018 nine-month period was primarily due to an increase in expected losses in our excess and surplus lines business, as previously discussed, and, to a lesser extent, the effect of a loss portfolio transfer (net premiums earned at a 95% loss ratio) entered into during the second quarter of 2018 in our Specialty P&C segment (see further discussion in our Segment Operating Results - Specialty Property & Casualty section

that follows). Partially offsetting the increase in the 2018 nine-month period was the effect of the aforementioned storm-related losses recognized in the third quarter of 2017 in our Lloyd's Syndicates segment.
In both the 2018 and 2017 three- and nine-month periods, our consolidated calendar year net loss ratio was lower than our consolidated current accident year net loss ratio due to the recognition of net favorable loss development, as shown in the previous table.

*There are no net premiums earned associated with the Corporate segment. Ratios shown are the contribution of the Corporate segment to the consolidated ratio (Corporate operating expenses divided by consolidated net premium earned).
Our consolidated underwriting expense remained relatively flat for the 2018 three-month period which primarily reflected an increase in operating expenses in our Lloyd's Syndicates segment, primarily due to the establishment of Syndicate 6131, almost entirely offset by an increase in net premiums earned across all of our operating segments.
Our consolidated underwriting expense ratio decreased for the 2018 nine-month period driven by a loss portfolio transfer (net premiums earned with minimal associated operating expenses) entered into during the second quarter of 2018 in our Specialty P&C segment, which accounted for 1.4 percentage points of the decrease in the consolidated underwriting expense ratio (see further discussion in our Segment Operating Results - Specialty Property & Casualty section that follows). After removing the impact of the loss portfolio transfer, the remaining decrease in the consolidated underwriting expense ratio for the 2018 nine-month period was primarily due to an increase in net premiums earned across all of our operating segments, largely offset by an increase in DPAC amortization in our Specialty P&C segment, due to an increase in commission and brokerage expenses, and an increase in operating expenses in our Lloyd's Syndicates segment, as previously discussed.
Taxes
Our projected annual effective tax rates for 2018 and 2017 were a benefit of 3.0% and an expense of 9.8% as of September 30, 2018 and 2017, respectively, before discrete items were considered. Due to the TCJA, the statutory federal income tax rate used to develop the projected annual effective tax rate for 2018 was lower than the statutory federal income tax rate used to develop the projected annual effective tax rate for 2017. The effect of the lower statutory federal income tax rate and our ability to utilize tax credits in the current tax year as well as the previous tax year through carryback provisions of the tax law resulted in our projected annual effective tax rate of a benefit of 3.0% as of September 30, 2018.
Our projected annual effective tax rates as of September 30, 2018 and 2017 were different from the statutory federal income tax rate primarily due to a portion of our investment income being tax-exempt and the utilization of tax credits transferred to us from our tax credit partnership investments. Discrete items further reduced our annual effective tax rates during the 2018 and 2017 nine-month periods by 2.8% and 5.1%, respectively, resulting in a total effective tax rate of a benefit of 5.8% and an expense of 4.7%, respectively. See further discussion, including notable discrete items during 2018 and 2017, in the Segment Operating Results - Corporate section that follows under the heading "Taxes."

The increase in both the 2018 three- and nine-month periods primarily reflected a higher net loss ratio in our Specialty P&C segment driven by a lower amount of prior year favorable development and a lower investment income ratio driven by a decline in income from our fixed maturity securities due to lower average investment balances. Increases in both the 2018 three- and nine-month periods were partially offset by a lower net loss ratio in our Lloyd's Syndicates segment due to the effect of prior period storm-related losses recognized during the third quarter of 2017 (see further discussion in the Segment Operating Results- Lloyd's Syndicates section that follows).
ROE
ROE is calculated as annualized net income for the period divided by the average of beginning and ending shareholders’ equity. This ratio measures our overall after-tax profitability and shows how efficiently capital is being used. ROE for the three and nine months ended September 30, 2018 and 2017 was as follows:

The increase in the 2018 three-month period was primarily due to an increase in net income and a lower average equity base as compared to the same period of 2017. The increase in net income was driven by the reduction of storm-related losses recognized in our Lloyd's Syndicates segment, as previously discussed, and, to a lesser extent, the change in net realized investment gains and losses in our equity trading portfolio as compared to the 2017 three-month period, almost entirely offset by a lower amount of prior year favorable development in our Specialty P&C segment. The lower average equity base was primarily due to cumulative dividend declarations since the prior period and, to a lesser extent, lower AOCI resulting from changes in unrealized gains and losses in our fixed maturity available-for-sale securities.
The decrease in the 2018 nine-month period was primarily due to a decrease in net income, partially offset by a lower average equity base as compared to the same period of 2017. The decrease in net income was driven by a lower amount of prior year favorable development in our Specialty P&C segment and the change in net realized investment gains and losses in our equity trading portfolio. The lower average equity base was primarily due to cumulative dividend declarations since the prior period and, to a lesser extent, lower AOCI resulting from changes in unrealized gains and losses in our fixed maturity available-for-sale securities.
Book Value per Share
Book value per share is calculated as total shareholders’ equity at the balance sheet date divided by the total number of
common shares outstanding. This ratio measures the net worth of the Company to shareholders on a per-share basis. Our book value per share at September 30, 2018 as compared to December 31, 2017 is shown in the following table.

We believe the payment of dividends is currently our most effective tool for the deployment of excess capital even though, in the short-term, dividend declarations dampen growth in book value per share. In addition, our book value per share at September 30, 2018 as compared to December 31, 2017 was impacted by a decrease in AOCI as a result of unrealized losses arising during the nine months ended September 30, 2018 related to our fixed maturity available-for-sale securities which are recognized as a component of OCI.
Non-GAAP Financial Measures
Non-GAAP operating income is a financial measure that is widely used to evaluate performance within the insurance sector. In calculating Non-GAAP operating income, we have excluded the after-tax effects of the items listed in the following table that do not reflect normal operating results. We believe Non-GAAP operating income presents a useful view of the performance of our insurance operations, however it should be considered in conjunction with net income computed in accordance with GAAP.
The following table is a reconciliation of net income to Non-GAAP operating income:

(1) Net realized investment gains (losses) on investments related to SPCs are recognized in our Segregated Portfolio Cell Reinsurance segment and the portion of operating earnings, including the gain or loss, net of our participation, is due to the external cell owners through the SPC dividend expense (income). To be consistent with our exclusion of net realized investment gains (losses) recognized in earnings, we are excluding the portion of net realized investment gains (losses) that is included in the SPC dividend expense (income) which is due to the external cell owners.
(2) The annual expected incremental tax rate for the three and nine months ended September 30, 2018 is 21% as compared to 35% for the same respective periods of 2017, associated with the taxable or tax deductible items listed above. Excluding certain discrete items, which are tax effected at the annual expected incremental tax rate in the period they are included in net income, the effective tax rate for each period was applied to these items in calculating net income.

Segment Operating Results - Specialty Property & Casualty
As previously discussed under the heading "ProAssurance Overview," we reorganized our segment reporting in the third quarter of 2018 which resulted in the creation of a new segment: Segregated Portfolio Cell Reinsurance. The underwriting results of the SPCs that assume healthcare professional liability business were previously reported in our Specialty P&C segment and are now reported in our Segregated Portfolio Cell Reinsurance segment. All prior period segment information has been recast to conform to the current period presentation. See further information regarding our segments in Note 13 of the Notes to Condensed Consolidated Financial Statements.
Our Specialty P&C segment focuses on professional liability insurance and medical technology liability insurance. Segment operating results reflected pre-tax underwriting profit or loss from these insurance lines, exclusive of investment results, which are included in our Corporate segment. Segment operating results included the following:

In the second quarter of 2018, we entered into a loss portfolio transfer with a large healthcare organization. Per the agreement, we will cover a specific inventory of existing claims as well as provide tail coverage. As the contract included both prospective (tail) coverage and retroactive coverage, we bifurcated the provisions of the contract and accounted for each component separately. As of the effective date, we recognized total net premiums written and earned of $26.6 million, comprised of $7.9 million of prospective coverage and $18.7 million of retroactive coverage, and total net losses and loss adjustment expenses of $25.4 million within our Specialty P&C segment for the nine months ended September 30, 2018. See further discussion in Note 4 of the Notes to Condensed Consolidated Financial Statements.
Premiums Written
Changes in our premium volume within our Specialty P&C segment are driven by four primary factors: (1) the amount of new business, (2) our retention of existing business, (3) the premium charged for business that is renewed, which is affected by rates charged and by the amount and type of coverage an insured chooses to purchase and (4) the timing of premium written through multi-period policies. In addition, premium volume may periodically be affected by shifts in the timing of renewals between periods. The healthcare professional liability market, which accounts for a majority of the revenues in this segment, remains challenging as physicians continue joining hospitals or larger group practices and are thus no longer purchasing individual or group policies in the standard market. In addition, some competitors have chosen to compete primarily on price; both factors may impact our ability to write new business and retain existing business.

Physician policies were our greatest source of premium revenues in both 2018 and 2017. The decrease in twelve month term policies during the 2018 three- and nine-month periods was primarily driven by retention losses and, to a lesser extent, timing differences related to the shifting in renewal dates of a few large policies. Decreases in both the 2018 three- and nine-month periods were largely offset by new business written, an increase in premiums assumed in which we participate on a quota share basis and an increase in coverage from one insured who acquired an entity who was not previously insured by us. Renewal pricing increases in both the 2018 three- and nine-month periods is reflective of our concern about potential increases in loss severity as well as more moderate marketplace price competition. We also offer twenty-four month term policies to our physician insureds in one selected jurisdiction. The decrease in twenty-four month term policies during the 2018 three- and nine-month periods, as compared to the same periods in 2017, primarily reflected the normal cycle of renewals (policies subject to renewal in 2018 were previously written in 2016 rather than in 2017).
(2) 
Our healthcare facilities premium (which includes hospitals, surgery centers and other similar facilities) increased during the 2018 three- and nine-month periods driven by new business written, primarily due to the addition of one large policy during the third quarter of 2018, and timing differences related to the renewal of certain policies, partially offset by retention losses. The increases in both the 2018 three- and nine-month periods also reflected increases in renewal pricing due to changes in loss experience related to a few large policies. Additionally, the 2018 nine-month period reflected an increase in coverage pertaining to one large entity which consolidated certain policies that were not previously insured by us during the first quarter of 2018.
(3) 
Our other healthcare providers are primarily dentists, chiropractors and allied health professionals.
(4) 
Our legal professionals policies are primarily individual and small group policies in select areas of practice. The increase during the 2018 three- and nine-month periods was primarily due to new business written and, to a lesser extent, an increase in the rate charged for certain renewed policies in select states due to rate filings, largely offset by retention losses.
(5) 
We offer extended reporting endorsement or "tail" coverage to insureds who discontinue their claims-made coverage with us, and we also periodically offer tail coverage through custom policies. The amount of tail coverage premium written can vary significantly from period to period. The decrease in tail premiums during the 2018 three-month period primarily reflected the effect of tail coverage purchased during the third quarter of 2017 for a few large claims-made policies in one jurisdiction that were rewritten to occurrence coverage. These policies are a part of one of our shared risk arrangements and therefore, a large portion of the premium written was ceded during the third quarter of 2017 (see further discussion in the Ceded Premiums Written section that follows). The increase in tail premiums during the 2018 nine-month period was driven by $7.9 million of tail coverage provided in connection with a loss portfolio transfer with a large healthcare organization entered into during the second quarter of 2018 (see further discussion in footnote 6 that follows), partially offset by the effect of the aforementioned tail coverage purchased in the third quarter of 2017.

We offer custom alternative risk solutions including loss portfolio transfers for large healthcare entities who, most commonly, are exiting a line of business, changing an insurance approach, or simply preferring to transfer risk. In the second quarter of 2018, we entered into a loss portfolio transfer with a large healthcare organization. Per the agreement, we will cover a specific inventory of existing claims as well as provide tail coverage. The premiums received for the coverage provided for the existing inventory of claims was classified as retroactive coverage and resulted in $18.7 million of one-time premium written and fully earned in the 2018 nine-month period. The premiums received for the prospective (tail) coverage resulted in $7.9 million of one-time premium written and fully earned in the 2018 nine-month period. See Note 4 of the Notes to the Condensed Consolidated Financial Statements for further information on this transaction.
(7) 
Our medical technology liability business is marketed throughout the U.S.; coverage is offered on a primary basis, within specified limits, to manufacturers and distributors of medical technology and life sciences products including entities conducting human clinical trials. In addition to the previously listed factors that affect our premium volume, our medical technology liability premium volume is impacted by the sales volume of insureds. The increase during the 2018 three- and nine-month periods was primarily due to new business written and, to a lesser extent, an increase in the premium charged for certain renewed policies as a result of an increase in the sales volume of certain insureds, partially offset by retention losses. Retention losses in both the 2018 three- and nine-month periods are largely attributable to an increase in competition on terms and pricing.
(8) 
Certain components include alternative market premiums. We cede either all or a portion of the alternative market premium, net of reinsurance, to certain SPCs of our wholly owned Cayman Islands reinsurance subsidiaries, Eastern Re and Inova Re, which are reported in our Segregated Portfolio Cell Reinsurance segment (see further discussion in the Ceded Premiums Written section that follows). The portion not ceded to the SPCs is retained within our Specialty P&C segment. Alternative market gross premiums written by component were as follows:

The increase in our alternative market healthcare facilities premium during the 2018 three- and nine-month periods was primarily due to new business written and, to a lesser extent, an increase in renewal pricing primarily due to increases in exposure related to a few policies, partially offset by retention losses.

For our Specialty P&C segment, we calculate our retention rate as annualized renewed premium divided by all annualized premium subject to renewal. Retention rates are affected by a number of factors. We may lose insureds to competitors or to alternative insurance mechanisms such as risk retention groups or self-insurance entities (often when physicians join hospitals or large group practices) or due to pricing or other issues. We may choose not to renew an insured as a result of our underwriting evaluation. Insureds may also terminate coverage because they have left the practice of medicine for various reasons, principally for retirement, death or disability, but also for personal reasons.

We are committed to a rate structure that will allow us to fulfill our obligations to our insureds, while generating competitive returns for our shareholders. Our pricing continues to be based on expected losses, as indicated by our historical loss data and available industry loss data. In recent years, this practice has resulted in gradual rate increases and we anticipate further rate increases due to indications of increasing loss severity. Additionally, the pricing of our business includes the effects of filed rates, surcharges and discounts. Renewal pricing also reflects changes in our exposure base, deductibles, self-insurance retention limits and other policy items.

Ceded Premiums Written
Ceded premiums represent the amounts owed to our reinsurers for their assumption of a portion of our losses. Through our current excess of loss reinsurance arrangements we generally retain the first $1 million in risk insured by us and cede coverages in excess of this amount. For our healthcare professional liability coverages, we also retain from 3% - 12.5% of the next $25 million of risk for coverages in excess of $1 million. For our medical technology liability coverages, we also retain 10% of the next $9 million of risk for coverages in excess of $1 million. We pay our reinsurers a ceding premium in exchange for their accepting the risk, the ultimate amount of which is determined by the loss experience of the business ceded, subject to certain minimum and maximum amounts.

We generally reinsure risks under our excess of loss reinsurance arrangements pursuant to which the reinsurers agree to assume all or a portion of all risks that we insure above our individual risk retention levels, up to the maximum individual limits offered. In the majority of our excess of loss reinsurance arrangements, the premium due to the reinsurer is determined by the loss experience of that business reinsured, subject to certain minimum and maximum amounts. The increase in ceded premiums written under our excess of loss reinsurance arrangements for the 2018 three- and nine-month periods primarily reflected an increase in the premiums we expect to owe our reinsurers based upon increases to our estimates of losses recoverable from our reinsurance partners.

As previously discussed, we are the majority participant in Syndicate 1729 and normally record our pro rata share of its operating results in our Lloyd's Syndicates segment on a quarter delay, except when information is available that is material to the current period. We also recorded the cession to the Lloyd's Syndicates segment from our Specialty P&C segment on a quarter delay as the amounts were not material and that permitted the cession to be reported by both the Lloyd's Syndicates segment and the Specialty P&C segment in the same reporting period. The decrease in premiums ceded to Syndicate 1729 during the 2018 three- and nine-month periods reflected the non-renewal of our quota share agreement with Syndicate 1729 on January 1, 2018; the impact of which was not reflected in ceded premiums written until the second quarter of 2018 due to the quarter delay. Additionally, the decrease in premiums ceded to Syndicate 1729 during the 2018 nine-month period reflected the revised contract terms on our previous quota share agreement effective January 1, 2017 which reduced the premiums ceded by essentially half. See the Segment Operating Results - Lloyd's Syndicates section for further discussion on the quota share agreement. As our premiums are earned, we recognize the related ceding commission income which reduces underwriting expense by offsetting DPAC amortization. For the 2018 nine-month period and 2017 three- and nine-month periods, the related ceding commission income was approximately 27% of ceded premiums written. For our consolidated results, eliminations of the inter-segment portion (58% of the Specialty P&C cession for the 2018 nine-month period and 2017 three- and nine-month periods) of the transactions are also recorded on a quarter delay.

We have entered into various shared risk arrangements, including quota share, fronting, and captive arrangements, with certain large healthcare systems and other insurance entities. These arrangements include our Ascension Health and CAPAssurance programs. While we cede a large portion of the premium written under these arrangements, they provide us an opportunity to grow net premium through strategic partnerships. The increase in the 2018 three- and nine-month periods was primarily driven by growth in our Ascension Health program, largely offset by a few large tail endorsements that were written, and substantially ceded, during the third quarter of 2017 related to one of these shared risk arrangements, as previously discussed.
(4) 
As previously discussed, as a part of our alternative market solutions, all or a portion of certain healthcare premium written is ceded to the SPCs in our Segregated Portfolio Cell Reinsurance segment under either excess of loss or quota share reinsurance agreements, depending on the structure of the individual program. See the Segment Operating Results - Segregated Portfolio Cell Reinsurance section for further discussion on the cession to the SPCs from our Specialty P&C segment. The increase in premiums ceded to the SPCs for the 2018 three- and nine-month periods was primarily driven by new business written (see discussion in footnote 8 under the heading "Gross Premiums Written").
(5) 
Given the length of time that it takes to resolve our claims, many years may elapse before all losses recoverable under a reinsurance arrangement are known. As a part of the process of estimating our loss reserve we also make estimates regarding the amounts recoverable under our reinsurance arrangements. As previously discussed, the premiums ultimately ceded under certain of our excess of loss reinsurance arrangements are subject to the losses ceded under the arrangements. For the 2018 and 2017 three- and nine-month periods, we reduced our estimate of expected losses and associated

recoveries for prior year ceded losses, as well as our estimate of ceded premiums owed to reinsurers. The change in the adjustment to ceded premiums owed to reinsurers for the 2018 three- and nine-month periods as compared to the same periods of 2017 was due to a lower amount of favorable development on prior year ceded losses. Changes to estimates of premiums ceded related to prior accident years are fully earned in the period the changes in estimates occur.
Ceded Premiums Ratio

The decrease in the current accident year ceded premiums ratio for the 2018 three- and nine-month periods was primarily due to the decrease in premiums ceded to Syndicate 1729, as previously discussed (see discussion under the heading "Ceded Premiums Written"). Additionally, the decrease in the 2018 nine-month period reflected the effect of the loss portfolio transfer entered into during the second quarter of 2018 (increase in gross premiums written with no premium ceded) which resulted in a 0.9 percentage point decrease in the current accident year ceded premiums ratio (see discussion under the heading "Gross Premiums Written").

Net premiums earned consist of gross premiums earned less the portion of earned premiums that we cede to our reinsurers for their assumption of a portion of our losses. Because premiums are generally earned pro rata over the entire policy period, fluctuations in premiums earned tend to lag those of premiums written. Generally, our policies carry a term of one year; however, as discussed above, we write certain policies with a twenty-four month term, and a few of our medical technology liability policies have a multi-year term. Tail coverage premiums are generally 100% earned in the period written because the policies insure only incidents that occurred in prior periods and are not cancellable. Retroactive coverage premiums are 100% earned at the inception of the contract, as all of the underlying loss events occurred in the past. Additionally, ceded premium changes due to changes to estimates of premiums owed under reinsurance agreements for prior accident years are fully earned in the period of change.
The increase in gross premiums earned during both the 2018 three- and nine-month periods included the pro rata effect of higher premiums written during the preceding twelve months, predominantly in our physicians line of business. The increase in both periods was partially offset by a few large tail policies written and earned during the third quarter of 2017 and a $2.3 million reduction in gross premiums earned in the third quarter of 2018 due to changes in premium on loss sensitive policies. The increase in the 2018 nine-month period, however, was driven by the effect of the loss portfolio transfer entered into during the second quarter of 2018 which resulted in $26.6 million of one-time premium written and fully earned in the current period (see discussion under the heading "Gross Premiums Written").
The decrease in ceded premiums earned during the 2018 three- and nine-month periods primarily reflected the pro rata effect of the decrease in premiums ceded to Syndicate 1729 during the preceding twelve months, partially offset by the change in prior accident year ceded premium adjustments, which were $1.7 million and $0.6 million lower as compared to the 2017 three- and nine-month periods, respectively (see discussion under the heading "Ceded Premiums Written").

Losses and Loss Adjustment Expenses
The determination of calendar year losses involves the actuarial evaluation of incurred losses for the current accident year and the actuarial re-evaluation of incurred losses for prior accident years, including an evaluation of the reserve amounts required for losses in excess of policy limits.
Accident year refers to the accounting period in which the insured event becomes a liability of the insurer. For claims-made policies, which represent the majority of the premiums written in our Specialty P&C segment, the insured event generally becomes a liability when the event is first reported to us. For occurrence policies, the insured event becomes a liability when the event takes place. For retroactive coverages, the insured event becomes a liability at inception of the underlying contract. We believe that measuring losses on an accident year basis is the best measure of the underlying profitability of the premiums earned in that period, since it associates policy premiums earned with the estimate of the losses incurred related to those policy premiums.
For the nine months ended September 30, 2018, our net loss ratio was affected by a loss portfolio transfer entered into during the second quarter of 2018 which resulted in total net premiums written and earned of $26.6 million and total net losses and loss adjustment expenses of $25.4 million (see further information in Note 4 of the Notes to Condensed Consolidated Financial Statements).
The following table summarizes calendar year net loss ratios by separating losses between the current accident year and all prior accident years. Additionally, the table shows our current accident year net loss ratio was affected by revisions to our estimate of premiums owed to reinsurers related to coverages provided in prior accident years. Net loss ratios were as follows:

Reductions to premiums owed under reinsurance agreements for prior accident years increased net premiums earned (the denominator of the current accident year ratio) for the 2018 and 2017 three- and nine-month periods. See the discussion in the Premiums section for our Specialty P&C segment under the heading "Ceded Premiums Written" for additional information.

The current accident year net loss ratio, excluding the effect of prior year ceded premium adjustments, for the 2018 three- and nine-month periods increased 4.3 and 2.9 percentage points, respectively, as compared to the same respective periods of 2017. During the third quarter of 2018, we reduced net premiums earned by $2.3 million due to changes in premium on loss sensitive policies which accounted for approximately 2.7 and 0.6 percentage points of the increase in the current accident year net loss ratio for the 2018 three- and nine-month periods, respectively. In addition, the increase in both the 2018 three- and nine-month periods was driven by an increase in expected losses in our excess and surplus lines business, which accounted for approximately 1.8 and 2.0 percentage points of the increase, respectively. The current accident year net loss ratio for 2018 nine-month period also reflected the effect of a loss portfolio transfer (net premiums earned at a 95% loss ratio) entered into during the second quarter of 2018, as previously discussed.
We recognized net favorable loss development related to our previously established reserves of $14.4 million and $55.0 million during the three and nine months ended September 30, 2018, respectively, and $30.1 million and $81.9 million during the same respective periods of 2017. We re-evaluate our previously established reserve each quarter based on our most recently available claims data and currently available industry trend information. Development recognized during the three and nine months ended September 30, 2018 principally related to accident years 2011 through 2015. Development recognized during the three and nine months ended September 30, 2017 principally related to accident years 2010 through 2014.

Table of Contents

A detailed discussion of factors influencing our recognition of loss development is included in our Critical Accounting Estimates section under the heading "Reserve for Losses and Loss Adjustment Expenses" and in our 2017 Form 10-K under the same heading. Assumptions used in establishing our reserve are regularly reviewed and updated by management as new data becomes available. Any adjustments necessary are reflected in the then current operations. Due to the size of our reserve, even a small percentage adjustment to the assumptions can have a material effect on our results of operations for the period in which the change is made, as was the case in both 2018 and 2017.

DPAC amortization increased for the three and nine months ended September 30, 2018 as compared to the same respective periods of 2017 driven by an increase in commission and brokerage expenses and, to a lesser extent, a decrease in ceding commission income, which is an offset to expense, primarily due to a reduction in premiums ceded to Syndicate 1729.
Management fees are charged pursuant to a management agreement by the Corporate segment to the operating subsidiaries within our Specialty P&C segment for services provided, based on the extent to which services are provided to the subsidiary and the amount of premium written by the subsidiary. While the terms of the management agreement were consistent between 2017 and 2018, fluctuations in the amount of premium written by each subsidiary can result in corresponding variations in the management fee charged to each subsidiary during a particular period. The management fees charged to the Specialty P&C segment for the 2018 nine-month period primarily reflected the increase in premiums written due to a loss portfolio transfer entered into during the second quarter of 2018 (see discussion under the heading "Gross Premiums Written").
Other underwriting and operating expenses increased during the 2018 three- and nine-month periods as compared to the same respective periods of 2017 primarily driven by the effect of a guaranty fund recoupment received in the third quarter of 2017, which is an offset to expense.
Underwriting Expense Ratio (the Expense Ratio)
Our expense ratio for the Specialty P&C segment for the three and nine months ended September 30, 2018 and 2017, respectively, was as follows:

The underwriting expense ratio remained relatively flat for the 2018 three-month period and decreased for the 2018 nine-month period as compared to the same respective periods of 2017. The decrease in the underwriting expense ratio for the 2018 nine-month period was due to the impact of a loss portfolio transfer entered into during the second quarter of 2018 (net premiums earned with minimal associated operating expenses), which accounted for a 1.5 percentage point decrease in the underwriting expense ratio (see further discussion under the heading "Gross Premiums Written"). After removing the impact of the loss portfolio transfer, the underwriting expense ratio increased slightly in the 2018 nine-month period primarily due to the effect of the increase in DPAC amortization, as previously discussed, largely offset by an increase in net premiums earned as compared to the same respective period of 2017.

Segregated Portfolio Cell Dividend (Expense) Income
During the third quarter of 2018, we reorganized our segment reporting which resulted in the creation of a new segment: Segregated Portfolio Cell Reinsurance (see further discussion under the heading "ProAssurance Overview"). The Segregated Portfolio Cell Reinsurance segment provides the results of SPCs at our Eastern Re and Inova Re subsidiaries, including SPCs that assume healthcare professional liability business which were previously reported within our Specialty P&C segment. As such, there is no longer a SPC dividend expense reported in the Specialty P&C segment associated with these SPCs. See more information on our Cayman Islands SPC operations in the Segment Operating Results - Segregated Portfolio Cell Reinsurance section that follows.
The SPC dividend expense for the nine months ended September 30, 2017 represented a one-time $5.2 million pre-tax expense related to previously unrecognized SPC dividend expense for the cumulative earnings of unrelated parties that have owned SPCs at various times since 2003 within a Bermuda captive insurance operation. Historically, within our HCPL business, we have written a limited number of segregated cell captive programs through this Bermuda captive arrangement and the use of this facility has declined as the HCPL insurance market has softened. The SPC dividend expense attributable to those cells was unrelated to the captive operations of our Eastern Re subsidiary.

Segment Operating Results - Workers' Compensation Insurance
As previously discussed under the heading "ProAssurance Overview," we reorganized our segment reporting in the third quarter of 2018 which resulted in the creation of a new segment: Segregated Portfolio Cell Reinsurance. The underwriting results of the SPCs at Eastern Re and Inova Re that assume workers’ compensation business were previously reported in our Workers’ Compensation segment and are now reported in our Segregated Portfolio Cell Reinsurance segment. The traditional workers' compensation business remains in the Workers' Compensation segment which has been renamed to "Workers' Compensation Insurance." All prior period segment information has been recast to conform to the current period presentation. See further information regarding our segments in Note 13 of the Notes to Condensed Consolidated Financial Statements.
Our Workers' Compensation Insurance segment provides workers' compensation products to employers generally with 1,000 or fewer employees. Workers' compensation products offered include guaranteed cost policies, policyholder dividend policies, retrospectively-rated policies, deductible policies and alternative market solutions. Alternative market products include program design, fronting, claims administration, risk management, SPC rental, asset management and SPC management services. Alternative market premiums are 100% ceded to either the SPCs within our Segregated Portfolio Cell Reinsurance segment or, to a limited extent, unaffiliated captive insurers. Our Workers' Compensation Insurance segment operating results reflected pre-tax underwriting profit or loss from these workers' compensation products, exclusive of investment results, which are included in our Corporate segment. Segment operating results included the following:

Gross premiums written in our traditional business increased during the three and nine months ended September 30, 2018 as compared to the same respective periods of 2017, which primarily reflected new business written, including $3.1 million and $11.1 million, respectively, of premiums written related to the third quarter 2017 acquisition of the Great Falls book of business and an improvement in renewal pricing. The growth in our alternative market business for the nine months ended September 30, 2018 primarily reflects new business written and an improvement in renewal pricing. We retained 16 of the 17 available alternative market programs up for renewal during the nine months ended September 30, 2018, including the 2 programs available for renewal during the third quarter of 2018.

(1) We calculate our workers' compensation retention rate as annualized expiring renewed premium divided by all annualized expiring premium subject to renewal. Our retention rate can be impacted by various factors, including price or other competitive issues, insureds being acquired, or a decision not to renew based on our underwriting evaluation.
(2) The pricing of our business includes an assessment of the underlying policy exposure and the effects of current market conditions. We continue to base our pricing on expected losses, as indicated by our historical loss data.

Our Workers' Compensation Insurance segment cedes alternative market business under a 100% quota share reinsurance agreement, net of a ceding commission, to SPCs in our Segregated Portfolio Cell Reinsurance segment. The ceding commission consists of an amount for fronting fees, cell rental fees, commissions, premium taxes, claims administration fees and risk management fees. The fronting fees, commissions, premium taxes and risk management fees are recorded as an offset to underwriting, policy acquisition and operating expenses (see discussion that follows under the heading "Underwriting, Policy Acquisition and Operating Expenses"). Cell rental fees are recorded as a component of other income and claims administration fees are recorded as ceded ULAE.
Under our external reinsurance agreement, we retain the first $0.5 million in risk insured by us and cede losses in excess of this amount on each loss occurrence under our primary external reinsurance contract. Per our reinsurance agreements, we cede premiums related to our traditional business on an earned premium basis. The increase in premiums ceded to external reinsurers during the three and nine months ended September 30, 2018 was driven by an increase in earned premium, an increase in reinsurance rates effective May 1, 2018 and a decrease in revenue sharing with our reinsurance broker, primarily due to a change in estimate during the second quarter of 2017.
The decrease in premiums ceded to unaffiliated captive insurers during the three and nine months ended September 30, 2018 reflected the impact of the 2017 designed consolidation of two unaffiliated captive programs. During 2017, we added one new alternative market program that writes business previously ceded to two non-renewed unaffiliated captive programs.
Changes in the return premium estimate reflected the loss experience under the reinsurance contract for the three and nine months ended September 30, 2018 and 2017. The decrease in the return premium estimate for the nine months ended September 30, 2018 primarily reflected unfavorable development on a reinsured claim in a prior contract year.

The above table reflects ceded premiums earned as a percent of gross premiums earned. As discussed above, we cede premiums related to our traditional business to external reinsurers on an earned premium basis. The increase in the ceded premiums ratio for the three and nine months ended September 30, 2018 when compared to the same respective periods of 2017 primarily reflected an increase in reinsurance rates and the impact of broker revenue sharing, as previously discussed.

Net premiums earned consist of gross premiums earned less the portion of earned premiums that we cede to SPCs in our Segregated Portfolio Cell Reinsurance segment, external reinsurers or unaffiliated captive insurers. Because premiums are generally earned pro rata over the entire policy period, fluctuations in premiums earned tend to lag those of premiums written. Our workers’ compensation policies are twelve-month policies and premiums are earned on a pro rata basis over the policy period. Net premiums earned also include premium adjustments related to the audit of our insureds' payrolls. Payroll audits are conducted subsequent to the end of the policy period and any related adjustments are recorded as fully earned in the current period. In addition, we record an estimate for EBUB and evaluate the estimate on a quarterly basis. We did not adjust the EBUB estimate during the three and nine months ended September 30, 2018 or 2017. The increase in net premiums earned primarily reflected the pro rata effect of higher net premiums written during the preceding twelve months.

The current accident year net loss ratio for the 2018 three- and nine-month periods was 70.7% and 68.0%, respectively, as compared to 66.1% and 66.0% for the same respective periods of 2017. The increase in the current accident year net loss ratio reflected an increase in claim trends in 2018, including the impact of severity-related claim activity related to economic growth trends and the increase in new and less experienced workers to the workforce.
Calendar year incurred losses ceded to our external reinsurers totaled $5.1 million and $18.2 million for the three and nine months ended September 30, 2018, respectively, compared to ceded incurred losses of $7.6 million and $14.7 million for the same respective periods of 2017. The increase in ceded incurred losses for the nine months ended September 30, 2018 primarily reflected the aforementioned increase in severity-related claim activity.
We recognized net favorable prior year development related to our previously established reserve of $2.8 million and $4.2 million for the three and nine months ended September 30, 2018, respectively, as compared to $0.4 million and $1.2 million for the same respective periods of 2017. The net favorable prior year development for the three and nine months ended September 30, 2018 reflected overall favorable trends in claim closing patterns, primarily in the 2015 and 2016 accident years. For both the three and nine months ended September 30, 2018 and 2017, the net favorable prior year development included $0.4 million and $1.2 million, respectively, related to the amortization of the purchase accounting fair value adjustment.
We estimate our current accident year loss and loss adjustment expenses based on an expected loss ratio. Incurred losses and loss adjustment expenses are determined by applying the expected loss ratio to net premiums earned, which includes audit premium, for the respective period.

Underwriting, Policy Acquisition and Operating Expenses
Underwriting, policy acquisition and operating expenses includes the amortization of commissions, premium taxes and underwriting salaries, which are capitalized and deferred over the related workers’ compensation policy period, net of ceding commissions earned. The capitalization of underwriting salaries can vary as they are subject to the success rate of our contract acquisition efforts. These expenses also include a management fee charged by our Corporate segment, which represents intercompany charges pursuant to a management agreement, and the amortization of intangible assets, primarily related to the acquisition of Eastern by ProAssurance. The management fee is based on the extent to which services are provided to the subsidiary and the amount of premium written by the subsidiary.

The increase in DPAC amortization for the three and nine months ended September 30, 2018 as compared to the same respective periods of 2017 primarily reflected the increase in net premiums earned. The increase in other underwriting and operating expenses for the three and nine months ended September 30, 2018 as compared to the same respective periods of 2017 primarily reflected an increase in expenses associated with the start-up of our New England region through the Great Falls acquisition and an increase in compensation related costs.
Alternative market premiums written through our Workers' Compensation Insurance segment's alternative market business unit are 100% ceded, less a ceding commission, to either the SPCs in our Segregated Portfolio Cell Reinsurance segment or, to a limited extent, unaffiliated captive insurers. SPC ceding commission income includes fronting fees, commissions, premium taxes and risk management fees, which are reported as an offset to underwriting, policy acquisition and operating expenses.

Segment Operating Results - Segregated Portfolio Cell Reinsurance
As previously discussed under the heading "ProAssurance Overview," we reorganized our segment reporting in the third quarter of 2018 which resulted in the creation of the Segregated Portfolio Cell Reinsurance segment. See further information regarding our segments in Note 13 of the Notes to Condensed Consolidated Financial Statements.
The Segregated Portfolio Cell Reinsurance segment reflects the operating results (underwriting profit or loss, plus investment results) of SPCs at Eastern Re and Inova Re, our Cayman Islands SPC operations. As of September 30, 2018, there were 24 (20 active) SPCs. The SPCs assume workers' compensation insurance, healthcare professional liability insurance or a combination of the two from our Workers' Compensation Insurance and Specialty P&C segments. SPCs are segregated pools of assets and liabilities that provide an insurance facility for a defined set of risks. Assets of each SPC are solely for the benefit of that individual cell and each SPC is solely responsible for the liabilities of that individual cell. Assets of one SPC are statutorily protected from the creditors of the others. Each SPC is owned, fully or in part, by an agency, group or association and the operating results of the SPCs are due to the owners of that cell. We participate to a varying degree in the results of selected SPCs and, for the SPCs in which we participate, our ownership interest is as low as 25% and as high as 85%. SPC operating results due to external cell owners are reflected as a SPC dividend expense in our Segregated Portfolio Cell Reinsurance segment. In addition, our Segregated Portfolio Cell Reinsurance segment includes the SPC investment results as the investments are solely for the benefit of the cell participants and investment results due to external cell owners are reflected in the SPC dividend expense. Segment operating results reflects our share of the underwriting and investment results of the SPCs in which we participate, and included the following:

During the first quarter of 2018, we restructured our Cayman Islands SPC operations. Effective January 1, 2018, all new and renewing alternative market business previously ceded to the SPCs at Eastern Re, with the exception of one program, is now ceded to SPCs operated by a newly formed wholly owned Cayman Islands subsidiary, Inova Re. As part of the restructuring, all SPCs previously operated by Eastern Re, with the exception of one program, ceased assuming new and renewing business on or after January 1, 2018. The external cell owners' cumulative undistributed earnings and the results of all SPCs for the current period due to external cell owners continue to be reported as SPC dividends payable and SPC dividend expense, respectively.

Premiums Written
Premiums in our Segregated Portfolio Cell Reinsurance segment are 100% assumed from either our Workers' Compensation Insurance or Specialty P&C segments. SPC premium volume is driven by five primary factors: (1) the amount of new business written, (2) retention of the existing book of business, (3) premium rates charged on the renewal book of business and, for workers' compensation business, (4) audit premium and (5) changes in payroll exposure.

Gross premiums written for the 2018 and 2017 three- and nine-month periods was primarily comprised of workers' compensation coverages assumed from our Workers' Compensation Insurance segment. Gross premiums written increased during the three and nine months ended September 30, 2018 as compared to the same respective periods of 2017, driven by new business written and an improvement in renewal pricing. We retained 16 of the 17 available alternative market programs up for renewal during the nine months ended September 30, 2018, including the 2 programs available for renewal during the third quarter of 2018.

(1) We calculate our workers' compensation retention rate as annualized expiring renewed premium divided by all annualized expiring premium subject to renewal. Our retention rate can be impacted by various factors, including price or other competitive issues, insureds being acquired, or a decision not to renew based on our underwriting evaluation.
(2) The pricing of our business includes an assessment of the underlying policy exposure and the effects of current market conditions. We continue to base our pricing on expected losses, as indicated by our historical loss data.

For the workers' compensation business, each SPC has in place its own external reinsurance arrangements. The healthcare professional liability business is assumed net of reinsurance from our Specialty P&C segment; therefore, there are no ceded premiums related to the healthcare professional liability business reflected in the table above. The risk retention for each loss occurrence ranges from $0.3 million to $0.35 million based on the program. Per the SPC external reinsurance agreements, premiums are ceded on a written premium basis and the slight increase in premiums ceded to external reinsurers during the three and nine months ended September 30, 2018 primarily reflected an increase in written premium. External reinsurance rates vary based on the alternative market program.

Net premiums earned consist of gross premiums earned less the portion of earned premiums that the SPCs cede to external reinsurers. Because premiums are generally earned pro rata over the entire policy period, fluctuations in premiums earned tend to lag those of premiums written. Policies ceded to the SPCs are twelve month term policies and premiums are earned on a pro rata basis over the policy period. Net premiums earned also include premium adjustments related to the audit of workers' compensation insureds' payrolls. Payroll audits are conducted subsequent to the end of the policy period and any related adjustments are recorded as fully earned in the current period. The increase in net premiums earned primarily reflected the pro rata effect of higher net premiums written during the preceding twelve months.
Net Investment Income and Net Realized Investment Gains (Losses)
Net investment income for the 2018 and 2017 three- and nine-month periods was primarily attributable to interest earned on available-for-sale fixed maturity investments, which primarily includes investment-grade corporate debt securities. Net realized investment gains during the 2018 and 2017 three- and nine-month periods primarily reflected changes in the value of the SPCs' equity trading portfolio.

The current accident year net loss ratio reflected the aggregate loss ratio for all programs. Loss reserves are estimated for each program on a quarterly basis. Due to the size of some of the programs, quarterly claims activity can cause the current accident year net loss ratio to fluctuate significantly from period to period. The increase in the accident year net loss ratio primarily reflected the impact of economic growth trends and an increase in new and less experienced workers to the workforce.
Calendar year incurred losses ceded to our external reinsurers increased $1.9 million and $0.3 million for the 2018 three- and nine-month periods, respectively, as compared to the same periods of 2017.
We recognized net favorable prior year development of $3.7 million and $8.2 million for the three and nine months ended September 30, 2018, respectively, and $1.9 million and $6.4 million for the same respective periods of 2017, which primarily reflected better than expected claim trends in the 2015, 2016 and 2017 accident years. The improved claim trends reflected lower frequency and severity than anticipated at the time the reserves were established.
Audit premium from workers' compensation insureds results in a decrease in the net loss ratio, whereas audit premium returned to workers' compensation insureds results in an increase in the net loss ratio. We recognized audit premium of $0.6 million and $1.0 million in the three and nine months ended September 30, 2018, respectively, and $0.3 million and $0.7 million in the same respective periods of 2017, the effect of which is reflected in the previous table. We estimate our current accident year losses and loss adjustment expenses based on the underlying actuarial methodologies without consideration of audit premium. As a result, we removed the effects of audit premium in the previous table for purposes of evaluating the current accident year net loss ratio.

DPAC amortization primarily represented the amortization of ceding commissions, which vary by program and are paid to our Workers' Compensation Insurance and Specialty P&C segments for premiums assumed. Ceding commissions include an amount for fronting fees, commissions, premium taxes and risk management fees, which are reported as an offset to underwriting, policy acquisition and operating expenses within our Workers' Compensation Insurance and Specialty P&C segments. In addition, ceding commissions paid to our Workers' Compensation Insurance segment include cell rental fees which are recorded as other income within our Workers' Compensation Insurance segment.

Segment Operating Results - Lloyd's Syndicates
Our Lloyd's Syndicates segment includes operating results from our participation in certain Syndicates in Lloyd's of London. We have a total capital commitment to support our Lloyd's Syndicate operations through 2022 of up to $200 million. For the 2018 underwriting year, we have satisfied our capital commitment with investment securities deposited with Lloyd's (also referred to as FAL) which at September 30, 2018 had a fair value of approximately $125.4 million, as discussed in Note 3 of the Notes to Condensed Consolidated Financial Statements.
We normally report results from our involvement in Lloyd's Syndicates on a quarter delay, except when information is available that is material to the current period. Furthermore, the investment results associated with our FAL investments and certain U.S. paid administrative expenses are reported concurrently as that information is available on an earlier time frame.
Lloyd's Syndicate 1729. We are the majority capital provider to Syndicate 1729, which covers a range of property and casualty insurance and reinsurance lines. For the 2018 underwriting year, we increased our participation in the operating results of Syndicate 1729 from 58% to 62% which, due to the quarter delay, was not reflected in our Lloyd's Syndicates segment results until the second quarter of 2018. The remaining capital for Syndicate 1729 is provided by unrelated third parties, including private names and other corporate members. Syndicate 1729 has a maximum underwriting capacity of £132.0 million for the 2018 underwriting year, of which £82.0 million ($106.9 million based on September 30, 2018 exchange rates) is our allocated underwriting capacity. We are satisfying our capital commitment to support Syndicate 1729 with our FAL securities, as discussed above.
Lloyd's Syndicate 6131. Beginning in the second quarter of 2018, our Lloyd's Syndicates segment includes the operating results of a SPA, Syndicate 6131, which began writing business effective January 1, 2018. As a SPA, Syndicate 6131 is only allowed to underwrite one quota share reinsurance contract with Syndicate 1729. We are the sole (100%) capital provider to Syndicate 6131 and are satisfying our capital commitment with our FAL securities, as previously discussed. Syndicate 6131 has a maximum underwriting capacity of £8.0 million ($10.4 million based on September 30, 2018 exchange rates) for the 2018 underwriting year and will focus on contingency and specialty property business.
For the three and nine months ended September 30, 2018 and 2017, our Lloyd's Syndicates segment results include our participation in Lloyd's of London Syndicates, as discussed above, and 100% of the operating results of our wholly owned subsidiaries that support our Lloyd's Syndicates and were composed as follows:

As previously discussed, we normally report results from our involvement in Lloyd's Syndicates on a quarter delay. However, during the third quarter of 2017, Syndicate 1729 reported preliminary loss estimates in connection with Hurricanes Harvey, Irma and Maria, which affected Texas, several states in the southeastern U.S. and islands in the Caribbean. Due to the availability and significance of these estimates, we accelerated our reporting of these storm-related losses into the third quarter of 2017. We estimated our share (58% for the 2017 underwriting year) of the net pre-tax losses from these storms to be approximately $7.5 million net of reinsurance and reinstatement premiums, which were written and earned during the third quarter of 2017. No such adjustments were made during the nine months ended September 30, 2018.
Gross Premiums Written
Changes in our premium volume within our Lloyd's Syndicates segment are driven by four primary factors: (1) the amount of new business and the channels in which the business is written, (2) our retention of existing business, (3) the premium charged for business that is renewed, which is affected by rates charged and by the amount and type of coverage an insured chooses to purchase and (4) the timing of premium written through multi-period policies.
Gross premiums written during the nine months ended September 30, 2018 consisted of casualty coverages (31% of total gross premiums written), property insurance coverages (37%), property reinsurance coverages (12%), catastrophe reinsurance coverages (17%) and specialty property coverages (3%). The increase in gross premiums written during the 2018 three- and nine-month periods as compared to the same respective periods of 2017 was primarily driven by our increased participation in the operating results of Syndicate 1729 and our participation in the operating results of Syndicate 6131, partially offset by the effect of reinstatement premiums received in the third quarter of 2017. The reinstatement premiums represented the additional premium payable to Syndicate 1729 to restore coverage limits that were exhausted under certain excess of loss reinsurance treaties as a result of the previously discussed reinsured storm-related losses and resulted in approximately $1.4 million of one-time premium written and fully earned during the third quarter of 2017.
As discussed in our Specialty P&C segment operating results, prior to January 1, 2018 Syndicate 1729 served as a reinsurer on a quota share basis for a wholly owned insurance subsidiary in our Specialty P&C segment. For premiums assumed, we include in gross premiums written an estimate of all premiums to be earned over the entire period covered by the reinsurance agreement, generally one year, in the quarter in which the reinsurance agreement becomes effective. Results from this ceding arrangement are reported in the Specialty P&C segment on the same quarter delay in order to be consistent with the Lloyd's Syndicates segment as the effect of doing so is not material. The quota share agreement with our Specialty P&C segment effective January 1, 2017 reflected revised contract terms which reduced premiums assumed by Syndicate 1729 by essentially half. Syndicate 1729 did not renew the quota share agreement with our Specialty P&C segment on January 1, 2018; however, due to the previously discussed quarter delay, the impact began to be reflected in each segment's operating results in second quarter of 2018.
The 2016 and 2015 calendar year quota share arrangements with our Specialty P&C segment were commuted in December 2017 and 2016, respectively. Due to the quarter delay, the effect of the 2016 and 2015 commutation was reported in both segments' results during the first quarters of 2018 and 2017, respectively, and is reflected in the Lloyd's Syndicates segment results for the nine months ended September 30, 2018 and 2017, respectively. The commutations did not differ significantly from previously recorded amounts.
Ceded Premiums Written
Syndicate 1729 utilizes reinsurance to provide capacity to write larger limits of liability on individual risks, to provide protection against catastrophic loss and to provide protection against losses in excess of policy limits. Ceded premiums written decreased in the three months ended September 30, 2018 primarily due to timing differences related to the purchase of reinsurance and changes to the estimate of premium owed under our reinsurance agreements as compared to the same period of 2017. Ceded premiums written increased for the nine months ended September 30, 2018 primarily due to the increased utilization of reinsurance on new business written directly by Syndicate 1729 to replace the business previously assumed through the quota share agreement with our Specialty P&C segment.
Net Premiums Earned
Net premiums earned consist of gross premiums earned less the portion of earned premiums that we cede to our reinsurers for their assumption of a portion of our losses. Premiums written through open-market channels are generally earned pro rata over the entire policy period, which is predominately twelve months, whereas premiums written through delegated underwriting authority arrangements are earned over twenty-four months. Therefore, net premiums earned is affected by shifts in the mix of policies written between the open-market and delegated underwriting authority arrangements. Additionally, fluctuations in premiums earned tend to lag those of premiums written. Premiums for certain policies and assumed reinsurance contracts are reported subsequent to the coverage period and/or may be subject to adjustment based on loss experience. These premium adjustments are earned when reported, which can result in further fluctuation in earned premium.

Table of Contents

The increase in net premiums earned during the 2018 three- and nine-month periods primarily reflected the pro rata effect of shifts in the mix of premiums written during the preceding twelve months; a larger proportion of premiums were written through the open-market, as compared to previous years, which are predominately earned over twelve months. Increases in both the 2018 three- and nine-month periods were partially offset by the effect of reinstatement premiums earned associated with the storm-related losses in the third quarter of 2017, as previously discussed. For the 2018 nine-month period, the increase in gross premiums earned was largely offset by an increase in ceded premiums earned which primarily reflected the effect of higher ceded premiums written during the preceding twelve months due to a revision in our reinsurance agreements at the beginning of 2017. Net premiums earned for the three and nine months ended September 30, 2018 included premium assumed from our Specialty P&C segment of approximately $1.2 million and $4.5 million, respectively, and approximately $2.9 million and $9.5 million for the same respective periods of 2017.
Net Losses and Loss Adjustment Expenses
Losses for the period were primarily recorded using the loss assumptions by risk category incorporated into the business plan submitted to Lloyd's for Syndicate 1729 with consideration given to loss experience incurred to date. The assumptions used in the business plan were consistent with loss results reflected in Lloyd's historical data for similar risks. Syndicate 6131, which began active operations effective January 1, 2018, follows a process similar to Syndicate 1729 for the establishment of initial reserves. We expect loss ratios to fluctuate from quarter to quarter as Syndicate 1729 writes more business and the book begins to mature. We also expect loss ratios of Syndicate 6131 to fluctuate from quarter to quarter as Syndicate 6131 assumes more business from Syndicate 1729. The loss ratios will also fluctuate due to the timing of earned premium adjustments (see discussion in this section under the heading "Net Premiums Earned"). Premium and exposure for some of Syndicate 1729's insurance policies and reinsurance contracts are initially estimated and subsequently adjusted over an extended period of time as underlying premium reports are received from cedants and insureds. When reports are received, the premium, exposure and corresponding loss estimates are revised accordingly. Changes in loss estimates due to premium or exposure fluctuations are incurred in the accident year in which the premium is earned.
The following table summarizes calendar year net loss ratios by separating losses between the current accident year and all prior accident years. Net loss ratios for the period were as follows:

The current accident year net loss ratio decreased during the three and nine months ended September 30, 2018, respectively, as compared to the same periods of 2017 driven by the effect of the aforementioned storm-related losses and reinstatement premiums recognized during the third quarter of 2017, which accounted for approximately 40.3 and 18.6 points, respectively, of the decrease in the current accident year net loss ratio. After removing the impact of the prior period storm-related losses and reinstatement premiums, the decrease in the current accident year net loss ratio for the 2018 three- and nine-month periods reflected shifts in the mix of business earned, as previously discussed.
We recognized $0.6 million of favorable prior year development and $0.3 million of unfavorable prior year development for the three and nine months ended September 30, 2018, respectively, as compared to $0.1 million of unfavorable prior year development and $0.6 million of favorable prior year development for the same respective periods of 2017. The unfavorable prior year development for the nine months ended September 30, 2018 was driven by higher than expected losses and development on certain large claims which resulted in unfavorable development with respect to a previous year of account, slightly offset by the favorable prior year development recognized during the third quarter of 2018.
Underwriting, Policy Acquisition and Operating Expenses
Underwriting, policy acquisition and operating expenses increased by $1.7 million and $4.0 million for the three and nine months ended September 30, 2018, respectively, as compared to the same periods in 2017. The increase in both the 2018 three- and nine-month periods was primarily due to the anticipated growth in Syndicate 1729 operations, an increase in various operational expenses associated with establishing Syndicate 6131 and, to a lesser extent, an increase in DPAC amortization primarily due to an increase in broker commissions.
The increase in the underwriting expense ratio for the three and nine months ended September 30, 2018 was primarily due to the previously mentioned increase in operating expenses and broker commissions, partially offset by an increase in net premiums earned, as previously discussed.

Investments
Net investment income for the 2018 and 2017 three- and nine-month periods was primarily attributable to interest earned on our FAL investments, which primarily includes investment-grade corporate debt securities. In the fourth quarter of 2017, Syndicate 1729 expanded its fixed maturities portfolio to include certain debt securities classified as trading securities. Investment results associated with these fixed maturity trading securities are reported on the same quarter delay.

Segment Operating Results - Corporate
As previously discussed under the heading "ProAssurance Overview," we reorganized our segment reporting in the third quarter of 2018 which resulted in the creation of a new segment: Segregated Portfolio Cell Reinsurance. The Segregated Portfolio Cell Reinsurance segment will include the results of investment assets solely allocated to SPC operations at our Cayman Islands reinsurance subsidiaries, Eastern Re and Inova Re, which were previously reported in our Corporate segment. All prior period segment information has been recast to conform to the current period presentation. See further information regarding our segments in Note 13 of the Notes to Condensed Consolidated Financial Statements.
Our Corporate segment includes investment operations, interest expense and U.S. income taxes, all of which are managed at the corporate level with the exception of investment assets solely allocated to either SPC operations or Lloyd's Syndicate operations. Our Corporate segment operating results also reflect non-premium revenues generated outside of our insurance entities and corporate expenses. Segment operating results for our Corporate segment were net earnings of $30.3 million and $58.7 million for the three and nine months ended September 30, 2018, respectively, and $19.9 million and $55.7 million for the same respective periods of 2017 and included the following:

Net Investment Income
Net investment income is primarily derived from the income earned by our fixed maturity securities and also includes dividend income from equity securities, income from our short-term and cash equivalent investments, earnings from other investments and increases in the cash surrender value of BOLI contracts. Investment fees and expenses are deducted from net investment income.

Fixed Maturities
The decrease in our investment income from fixed maturity securities for the 2018 three- and nine-month periods was due to lower average fixed maturity investment balances. We reduced the size of our fixed maturity portfolio over the last year in order to pay dividends and invest in other asset classes. On an overall basis, our average investment in fixed maturity securities was approximately 16% and 17% lower for the 2018 three- and nine-month periods, respectively, as compared to the same respective periods of 2017.
Average yields for our fixed maturity portfolio were as follows:

Equities
Income from our equity portfolio increased during the 2018 three- and nine-month periods as compared to the same respective periods of 2017 which reflected an increase to our allocation to this asset category as well as a different mix of equities owned.
Other Investments and Short-term Investments
Short-term investments, which have a maturity at purchase of one year or less are carried at fair value, which approximates their cost basis, and are primarily composed of investments in U.S. treasury obligations, commercial paper and money market funds. Income from our other investments and short-term investments increased during the 2018 three- and nine-month periods as compared to the same respective periods of 2017 primarily due to higher earnings from our short-term investment holdings due to higher interest rates.

We hold interests in certain LPs/LLCs that generate earnings from trading portfolios, secured debt, debt securities, multi-strategy funds and private equity investments. The performance of the LPs/LLCs is affected by the volatility of equity and credit markets. For our investments in LPs/LLCs, we record our allocable portion of the partnership operating income or loss as the results of the LPs/LLCs become available. Our investment results from our portfolio of investments in LPs/LLCs for the 2018 three- and nine-month periods were affected primarily by the adoption of an accounting standard during the first quarter of 2018 around the recognition and measurement of financial assets and financial liabilities (see Note 1 of the Notes to Condensed Consolidated Financial Statements for additional detail regarding accounting changes adopted during the period). Under the new accounting standard, LPs/LLCs previously reported using the cost method are now reported at fair value with changes in fair value recognized in equity in earnings (loss) of unconsolidated subsidiaries. Excluding the effect of the adoption of the new accounting standard, our investment results from our portfolio of investments in LPs/LLCs decreased for the 2018 three- and nine-month periods primarily due to lower reported earnings from a few LP investments.
Our tax credit partnership investments are designed to generate returns in the form of tax credits and tax-deductible project operating losses and are comprised of qualified affordable housing project tax credit partnerships and historic tax credit partnerships. We account for our tax credit partnership investments under the equity method and record our allocable portion of the operating losses of the underlying properties based on estimates provided by the partnerships. For our qualified affordable housing project tax credit partnerships, we adjust our estimates of our allocable portion of operating losses periodically as actual operating results of the underlying properties become available. Our historic tax credit partnerships are short-term in nature and remaining operating losses are expected to be recognized primarily in 2018. Based on operating results received, we increased our estimate of partnership operating losses by $0.4 million and $3.1 million for the 2018 three- and nine-month periods as compared to $0.2 million and $2.3 million for the same respective periods of 2017. The results from our tax credit

partnership investments for the three and nine months ended September 30, 2018 reflected an increase in partnership operating losses as compared to the same respective periods of 2017.
The tax benefits received from our tax credit partnerships, which are not reflected in our investment results above, reduced our tax expenses in 2018 and 2017 as follows:

Tax credits provided by the underlying projects of the historic tax credit partnerships are typically available in the tax year in which the project is put into active service, whereas the tax credits provided by qualified affordable housing project tax credit partnerships are provided over approximately a ten year period. The decrease in tax credits recognized for the three and nine months ended September 30, 2018 was primarily attributable to our qualified affordable housing project tax credit partnerships.
Non-GAAP Financial Measure – Tax Equivalent Investment Result
We believe that to fully understand our investment returns it is important to consider the current tax benefits associated with certain investments as the tax benefit received represents a portion of the return provided by our tax-exempt bonds, BOLI, common and preferred stocks, and tax credit partnership investments (collectively, our tax-preferred investments). We impute a pro forma tax-equivalent result by estimating the amount of fully-taxable income needed to achieve the same after-tax result as is currently provided by our tax-preferred investments. We believe this better reflects the economics behind our decision to invest in certain asset classes that are either taxed at lower rates and/or result in reductions to our current federal income tax expense. Our pro forma tax-equivalent investment result is shown in the table that follows as well as a reconciliation of our GAAP net investment result to our tax equivalent result.

Operating expenses remained relatively flat for the 2018 three-month period and decreased for the 2018 nine-month period as compared to the same respective periods of 2017. The decrease in the 2018 nine-month period was primarily driven by a decrease in share-based compensation expenses and other compensation related costs and, to a lesser extent, a decrease in professional fees as compared to the same respective period of 2017. The decrease in share-based compensation expense in the 2018 nine-month period was attributable to fewer awards outstanding and an adjustment of the projected award value based upon the decline of one of the performance metrics associated with a particular year's award.
Operating subsidiaries within our Specialty P&C and Workers' Compensation Insurance segments are charged a management fee by the Corporate segment for services provided to these subsidiaries. The management fee is based on the extent to which services are provided to the subsidiary and the amount of premium written by the subsidiary. Under the arrangement, the expenses associated with such services are reported as expenses of the Corporate segment, and the management fees charged are reported as an offset to Corporate operating expenses. While the terms of the arrangement were consistent between 2017 and 2018, fluctuations in the amount of premium written by each subsidiary can result in corresponding variations in the management fee charged to each subsidiary during a particular period. The management fees charged during the nine months ended September 30, 2018 primarily reflected the increase in premiums written in our Specialty P&C segment due to a loss portfolio transfer entered into during the second quarter of 2018 (see further discussion in our Segment Operating Results - Specialty Property & Casualty section).

Consolidated interest expense decreased during the three and nine months ended September 30, 2018 driven by a decrease in the weighted average outstanding borrowings on our Revolving Credit Agreement and the change in the fair value of our interest rate cap, partially offset by interest expense incurred on our Mortgage Loans. There were no outstanding borrowings on our Revolving Credit Agreement during the 2018 three-month period compared to weighted average outstanding borrowings of $158 million for the 2017 three-month period; interest expense for the third quarter of 2018 primarily reflected unused commitment fees. For the 2018 nine-month period, the weighted average outstanding borrowings on our Revolving Credit Agreement were $55 million as compared to $182 million for the same respective period of 2017. The interest rate cap was entered into during the fourth quarter of 2017 and is designated as an economic hedge of interest rate risk associated with our variable rate Mortgage Loans. See further discussion of our outstanding debt in Note 8 and further discussion of our interest rate cap agreement in Note 9 of the Notes to Condensed Consolidated Financial Statements.
Taxes
Tax expense allocated to our Corporate segment includes U.S. tax only, which would include U.S. tax expense incurred from our corporate membership in Lloyd's of London and tax expense incurred from SPCs at Inova Re, one of our Cayman Islands reinsurance subsidiaries, which intend to elect to be taxed as U.S. taxpayers. The U.K. tax expense incurred by the U.K. based subsidiaries of our Lloyd's Syndicates segment is allocated to that segment. Consolidated tax expense reflects tax expense of both segments, as shown in the table below:

Table of Contents

The provision (benefit) for income taxes and the effective tax rate for the 2018 and 2017 three- and nine-month periods are determined based upon our current estimate of our annual effective tax rate at the end of each quarterly reporting period (the projected annual effective tax rate) plus the impact of certain discrete items that are not included in the projected annual effective tax rate. Our projected annual effective tax rates for 2018 and 2017 were a benefit of 3.0% and an expense of 9.8% at September 30, 2018 and 2017, respectively, before consideration of discrete items. Our projected annual effective tax rates for both the 2018 and 2017 nine-month periods were different from the statutory federal income tax rate primarily due to a portion of our investment income being tax-exempt and the utilization of tax credits transferred to us from our tax credit partnership investments. Tax credits utilized were $5.2 million and $15.8 million for the three and nine months ended September 30, 2018, respectively, and $6.0 million and $17.8 million for the same respective periods of 2017. The effect of the lower statutory federal income tax rate as a result of the TCJA and our ability to utilize these tax credits in the current tax year as well as the previous tax year through carryback provisions of the tax law resulted in our projected annual effective tax rate of a benefit of 3.0% at September 30, 2018. While projected tax credits for 2018 are less than 2017, they continue to have a significant impact on the effective tax rate for the 2018 three- and nine-month periods.
Our effective tax rates for the 2018 and 2017 nine-month periods was a benefit of 5.8% and an expense of 4.7%, respectively, and differs from the projected annual effective tax rates due to certain discrete items. These discrete items reduced our projected annual effective tax rates by 2.8% and 5.1% for the 2018 and 2017 nine-month periods, respectively.
For the 2018 nine-month period, one notable discrete item that increased our effective tax rate was the treatment of net realized investment gains. Our calculation of our projected annual effective tax rate during interim periods has historically included an estimate of annual net realized investment gains and losses based on year-to-date results. Due to the recent volatility in the securities markets, we believe that projections for changes in net realized investment gains and losses during the year cannot be reliably estimated and could cause a significant distortion in the projected annual effective tax rate. Therefore, beginning in the first quarter of 2018, net realized investment gains and losses are treated as discrete items and reflected in the effective tax rate in the period in which they are included in income. This treatment of net realized investment gains of $2.6 million in our Corporate segment and $0.5 million in our Segregated Portfolio Cell Reinsurance segment for the nine months ended September 30, 2018 accounted for an increase of 1.1% in the projected annual effective tax rate.
Additionally, discrete items for the 2018 nine-month period included a tax benefit of $2.6 million related to provision to return differences. These differences primarily reflected higher tax credits received for the 2017 tax year than the estimated tax benefit as well as the difference in the statutory federal income tax rates for current and deferred taxes as a result of the TCJA, as discussed above. The treatment of the provision to return differences decreased our effective tax rate by 3.8% and more than offset the increase related to the treatment of net realized investment gains.
For the 2017 nine-month period, the most significant discrete item that decreased our effective tax rate was the excess tax benefit on share-based compensation that resulted from the application of revised accounting guidance, which was effective January 1, 2017, and lowered the effective tax rate by 2.8%. Under the revised guidance, the difference between the deduction for tax purposes, which is based upon the fair market value of share-based awards and the time of vesting, and the compensation cost recognized for financial reporting purposes, which is based upon the fair market value of the share-based awards on the date of grant, is to be recognized as income tax expense (benefit) in the current period rather than an adjustment to OCI as was required under prior guidance. Another discrete item in 2017 which increased our effective tax rate was the exclusion of a tax benefit for U.K. losses in our Lloyd's Syndicate segment that resulted from the application of accounting guidance related to interim period taxes for entities subject to multiple tax jurisdictions. Under this accounting guidance, an entity anticipating an ordinary loss in a jurisdiction for which no tax benefit can be recognized must exclude the loss and related tax benefit from the overall calculations of the estimated annual effective tax rate and interim period tax.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.
We believe that we are principally exposed to three types of market risk related to our investment operations. These risks are interest rate risk, credit risk and equity price risk. We are also exposed to interest rate risk related to our variable rate Mortgage Loans and Revolving Credit Agreement. We have limited exposure to foreign currency risk as we issue few insurance contracts denominated in currencies other than the U.S. dollar and we have few monetary assets or obligations denominated in foreign currencies.
Interest Rate Risk
Investments
Our fixed maturities portfolio is exposed to interest rate risk. Fluctuations in interest rates have a direct impact on the market valuation of these securities. As interest rates rise, market values of fixed income portfolios fall and vice versa. Certain of the securities are held in an unrealized loss position; we do not intend to sell and believe we will not be required to sell any of the debt securities held in an unrealized loss position before its anticipated recovery.
The following tables summarize estimated changes in the fair value of our available-for-sale fixed maturity securities for specific hypothetical changes in interest rates by asset class at September 30, 2018 and December 31, 2017. There are principally two factors that determine interest rates on a given security: changes in the level of yield curves and credit spreads. As different asset classes can be affected in different ways by movements in those two factors, we have separated our portfolio by asset class in the following tables.

Computations of prospective effects of hypothetical interest rate changes are based on numerous assumptions, including the maintenance of the existing level and composition of fixed income security assets, and should not be relied on as indicative of future results.
Certain shortcomings are inherent in the method of analysis presented in the computation of the fair value of fixed rate instruments. Actual values may differ from the projections presented should market conditions vary from assumptions used in the calculation of the fair value of individual securities, including non-parallel shifts in the term structure of interest rates and changing individual issuer credit spreads.
At September 30, 2018, our fixed maturities portfolio includes an immaterial amount of fixed maturities classified as trading securities. Because these trading securities are immaterial, there is not a significant amount of exposure to market interest rates or credit spreads.
Our cash and short-term investment portfolio at September 30, 2018 was carried at fair value which approximates their cost basis due their short-term nature. Our cash and short-term investments portfolio lacks significant interest rate sensitivity due to its short duration.
Debt
Our variable interest rate Mortgage Loans are exposed to interest rate risk. However, a 1% change in LIBOR will not materially impact our annualized interest expense. Additionally, we have economically hedged the risk of a change in interest rates in excess of 1% on the Mortgage Loans through the purchase of an interest rate cap derivative instrument, which effectively caps our annual interest rate on the Mortgage Loans at a maximum of 3.675% (see Note 9 of the Notes to Condensed Consolidated Financial Statements for additional information). The fair value of the interest rate cap is not materially impacted by a 1% change in LIBOR; however, the carrying value of the interest rate cap is impacted by future expectations for LIBOR as well as estimations of volatility in the future yield curve.
Our Revolving Credit Agreement is exposed to interest rate risk as it is LIBOR based and a 1% change in LIBOR will impact annual interest expense only to the extent that there is an outstanding balance. For every $100 million drawn on our Revolving Credit Agreement, a 1% change in interest rates will change our annual interest expense by $1 million. Any outstanding balances on the Revolving Credit Agreement can be repaid on each maturity date, which has typically ranged from one to three months. As of September 30, 2018, no borrowings were outstanding under our Revolving Credit Agreement.

Credit Risk
We have exposure to credit risk primarily as a holder of fixed income securities. We control this exposure by emphasizing investment grade credit quality in the fixed income securities we purchase.
As of September 30, 2018, 94% of our fixed maturity securities were rated investment grade as determined by NRSROs, such as Fitch, Moody’s and Standard & Poor’s. We believe that this concentration in investment grade securities reduces our exposure to credit risk on our fixed income investments to an acceptable level. However, investment grade securities, in spite of their rating, can rapidly deteriorate and result in significant losses. Ratings published by the NRSROs are one of the tools used to evaluate the credit worthiness of our securities. The ratings reflect the subjective opinion of the rating agencies as to the creditworthiness of the securities; therefore, we may be subject to additional credit exposure should the ratings prove to be unreliable.
We also have exposure to credit risk related to our receivables from reinsurers. Our receivables from reinsurers (with regard to both paid and unpaid losses) approximated $342 million at September 30, 2018 and $343 million at December 31, 2017. We monitor the credit risk associated with our reinsurers using publicly available financial and rating agency data.
Equity Price Risk
At September 30, 2018, the fair value of our equity investments, excluding our equity investments in bond investment funds as discussed in the following paragraph, was $292 million. These equity securities are subject to equity price risk, which is defined as the potential for loss in fair value due to a decline in equity prices. The weighted average beta of this group of securities was 0.92. Beta measures the price sensitivity of an equity security or group of equity securities to a change in the broader equity market, in this case the S&P 500 Index. If the value of the S&P 500 Index increased by 10%, the fair value of these securities would be expected to increase by 9.2% to $319 million. Conversely, a 10% decrease in the S&P 500 Index would imply a decrease of 9.2% in the fair value of these securities to $265 million. The selected hypothetical changes of plus or minus 10% do not reflect what could be considered the best or worst case scenarios and are used for illustrative purposes only.
Our equity investments include equity investments in certain bond investment funds which are not subject to significant equity price risk, and thus we have excluded these investments from the above analysis.

ITEM 4. CONTROLS AND PROCEDURES.
The principal executive officer and principal financial officer of the Company participated in management’s evaluation of our disclosure controls and procedures (as defined in SEC Rule 13a-15(e)) as of September 30, 2018. ProAssurance’s disclosure controls and procedures are designed to reasonably assure that information required to be disclosed by us in reports we file or submit under the Exchange Act is accumulated and communicated to our management as appropriate to allow timely decisions regarding disclosure and is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Based on that evaluation, the principal executive officer and principal financial officer have concluded that our disclosure controls and procedures are effective.
Changes in Internal Control over Financial Reporting
There have been no significant changes in our internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, those controls during the quarter.
