Item 2 - Controls and Procedures

2(a) -   The Registrant's principal executive and principal financial officers
         have evaluated the Registrant's disclosure controls and procedures,
         including internal control over financial reporting, within 90 days of
         this filing.  Such principal officers have concluded that as of
         January 23, 2007 the Registrant's disclosure controls and procedures
         were effective in design and operation to reasonably ensure that
         information required to be disclosed by the Registrant in this Form
         N-Q was recorded, processed, summarized, and reported within the
         required time periods, and were sufficient to form the basis of the
         certifications required by Rule 30a-2 of the Investment Company Act of
         1940, as amended.  Prior to reaching that conclusion, such principal
         officers had become aware of matters relating to the Registrant's
         participation in certain inverse floater structures that necessitated
         adjustments to financial information included in the Registrant's
         annual report to shareholders on Form N-CSR.  As a result, management
         of the Registrant had reevaluated certain disclosure controls and
         procedures determined not to be effective, as discussed more fully
         below.

         Management of the Registrant is responsible for establishing and
         maintaining effective internal control over financial reporting.  In
         fulfilling this responsibility, estimates and judgments by management
         are required to assess the expected benefits and related costs of
         controls.  The Registrant's internal control over financial reporting
         is a process designed to provide reasonable assurance regarding the
         reliability of financial reporting and the preparation of financial
         statements for external purposes in accordance with U.S. generally
         accepted accounting principles.  Such internal control includes
         policies and procedures that provide reasonable assurance regarding
         prevention or timely detection of unauthorized acquisition, use or
         disposition of a registrant's assets that could have a material effect
         on the financial statements.

         Because of its inherent limitations, internal control over financial
         reporting may not prevent or detect misstatements.  Also, projections
         of any evaluation of effectiveness to future periods are subject to
         the risk that controls may become inadequate because of changes in
         conditions, or that the degree of compliance with the policies or
         procedures may deteriorate.

         A control deficiency exists when the design or operation of a control
         does not allow management or employees, in the normal course of
         performing their assigned functions, to prevent or detect
         misstatements on a timely basis.  A significant deficiency is a
         control deficiency, or combination of control deficiencies, that
         adversely affects the Registrant's ability to initiate, authorize,
         record, process or report financial data reliably in accordance with
         generally accepted accounting principles such that there is more than
         a remote likelihood that a misstatement of the Registrant's annual or
         interim financial statements that is more than inconsequential will
         not be prevented or detected.  A material weakness is a significant
         deficiency, or combination of significant deficiencies, that results
         in more than a remote likelihood that a material misstatement of the
         annual or interim financial statements will not be prevented or
         detected.

         The Registrant identified the following control deficiency, that was
         determined to be a material weakness, as defined above, in the
         Registrant's internal control over financial reporting at October 31,
         2006.  The Registrant's controls related to the review and analysis
         of relevant terms and conditions of transfers of certain assets
         pertaining to inverse floater structures were not operating
         effectively to appropriately determine whether the transfers of assets
         qualified for sale accounting under the provisions of Statement of
         Financial Accounting Standards No. 140, "Accounting for Transfers and
         Servicing of Financial Assets and Extinguishments of Liabilities"
         ("SFAS 140").  As a result, these controls did not detect that certain
         transfers were not appropriately recorded as borrowings.  Accordingly,
         the Registrant's schedule of investments as of and for the period
         ended October 31, 2006, were restated  to appropriately reflect
         transfers of such securities as secured borrowings.  These adjustments
         had no impact on net assets, net asset value per share or total
         return.

         Subsequent to October 31, 2006, but prior to the evaluation of the
         design and operation of the Registrant's disclosure controls and
         procedures at January 23, 2007, the Registrant's disclosure controls
         and procedures were modified to enhance the review and analysis of the
         relevant terms and conditions of transfers of securities in connection
         with inverse floater structures in light of SFAS 140.

2(b) -   There have been no changes in the registrant's internal control over
         financial reporting (as defined in Rule 30a-3(d) under the Act
         (17 CFR 270.30a-3(d)) that occurred during the last fiscal quarter of
         the period covered by this report that has materially affected, or are
         reasonably likely to materially affect, the registrant's internal
         control over financial reporting. However, as discussed above,
