Item 7.01  Regulation FD Disclosure

                  On July 26, 2006 ProAssurance Corporation announced that
         shareholders of Physicians Insurance Company of Wisconsin (PIC
         Wisconsin) have approved PIC Wisconsin's merger into ProAssurance.

                  PIC Wisconsin's merger into ProAssurance is expected to be
         declared effective at 12:01 am on August 1, 2006. Each share of PIC
         Wisconsin common stock will be converted into shares of ProAssurance
         common stock having a value of $5,000. The number of shares of
         ProAssurance common stock to be issued per PIC Wisconsin share will be
         determined after the close of normal NYSE trading on Monday, July 31,
         2006, which is the end of a ten-day pricing period for valuing
         ProAssurance stock for purposes of this transaction. Instructions for
         submitting PIC Wisconsin shares for conversion will be mailed to
         shareholders no later than August 14, 2006.
