Item 9. Regulation FD Disclosure.

1.      PMA Capital Corporation has made a public filing with the Pennsylvania Insurance Department of an application for a determination that Section 991.1402 of the Pennsylvania Insurance Holding Company Act (the “Act”) does not apply to, or in the alternative, for an order of exemption under Section 991.1402(g) of the Act in connection with a proposed modification of the structure of its insurance holding company system. The proposed modification would result in its wholly owned indirect insurance subsidiaries, Pennsylvania Manufacturers’ Association Insurance Company, Pennsylvania Manufacturers Indemnity Company and Manufacturers Alliance Insurance Company (the “Pool Companies”), becoming its direct wholly owned subsidiaries. The proposed modification, which would be accomplished by the payment of a dividend of the capital stock of the Pool Companies by PMA Capital Insurance Company, is subject to Pennsylvania Insurance Department approval.
