     Note: Operating income (loss), which we define as net income (loss) under
     GAAP excluding net realized investment gains and losses, is the financial
     performance measure used by our management and Board of Directors to
     evaluate and assess the results of our insurance businesses. Accordingly,
     we report operating income by segment in the disclosures required under
     SFAS No. 131, "Disclosures About Segments of an Enterprise and Related
     Information." Our management and Board of Directors use operating income
     (loss) as the measure of financial performance for our insurance operations
     because (i) net realized investment gains and losses are unpredictable and
     not necessarily indicative of current operating fundamentals or future
     performance of the business segments and (ii) in many instances, decisions
     to buy and sell securities are made at the holding company level, and such
     decisions result in net realized gains and losses that do not relate to the
     operations of the individual segments. Operating income (loss) does not
     replace net income (loss) as the GAAP measure of our consolidated results
     of operations. See page 1 for reconciliations of operating results by
     segment to GAAP net income (loss).

1    In November 2003 we announced our decision to withdraw from the reinsurance
     business  previously served by our PMA Re operating segment. As a result of
     this  decision,  the results of PMA Re are reported as Run-off  Operations.
     Run-off  Operations  also  includes  the  results of our former  excess and
     surplus lines segment, Caliber One.

   1      In November 2003 we announced our decision to withdraw from the
          reinsurance business previously served by our PMA Re operating
          segment. As a result of this decision, the results of PMA Re are
          reported as Run-off Operations. Run-off Operations also includes the
          results of our former excess and surplus lines segment, Caliber One.

1    In November 2003 we announced our decision to withdraw from the reinsurance
     business previously served by our PMA Re operating segment. As a result of
     this decision, the results of PMA Re are reported as Run-off Operations.
     Run-off Operations also includes the results of our former excess and
