         On February 28, 2006 we filed a press release reporting the results of
our operations for the fourth quarter and year ended December 31, 2005. A copy
of the press release was filed in a current report on Form 8K on March 1, 2006

         In that news release we reported the results of our Personal Lines

Results for all periods reported reflected these adjustments.
