Item 2.01  Completion of Acquisition or Disposition of Asset

     On August 1, 2006, the ProAssurance Corporation ("ProAssurance") completed
its acquisition of Physicians Insurance Company of Wisconsin, Inc.
("PIC Wisconsin") through the merger of PIC Wisconsin and
a newly formed subsidiary of ProAssurance pursuant to the Agreement and Plan of
Merger between ProAssurance and PIC Wisconsin, dated December 8, 2005
and amended February 14, 2006. In accordance with the terms of the merger
agreement, each share of PIC Wisconsin common stock was
converted into 102.75 shares of ProAssurance common stock resulting in
approximately two million shares of ProAssurance common stock being issued in
the transaction. The merger agreement valued PIC Wisconsin
shares at $5,000 each. The value of a share of ProAssurance stock, for purposes
of determining the exchange ratio, was $48.66 based on the average NYSE closing
price for a ten day period that ended with the close of trading on July 31,
2006.

     The shares of ProAssurance common stock issued in the merger were
registered under the Securities Act of 1933 pursuant to a Registration Statement
on Form S-4 declared effective by the SEC on June 6, 200 (SEC File No.
333-131874). The merger is described in greater detail in the proxy
statement-prospectus included in the registration statement that was mailed to
the shareholders of PIC Wisconsin on or about June 13, 2006.



Item 7.01     Regulation FD Disclosure

     On August 1, 2006 we issued a news release announcing that PIC Wisconsin's
merger into ProAssurance was effective at 12:01 AM on that date, that William T.
Montei would be resigning as President of PIC Wisconsin, and that David L.
Maurer, PIC Wisconsin's Chief Operating Officer, would be assuming
responsibility for ongoing operations at PIC. A copy of the news release we
issued to announce the effectiveness of the merger and executive changes for PIC
Wisconsin is furnished with this report as Exhibit 99.1 and is incorporated into
this Item 7.01 by reference.

              (a)  Financial Statements of Businesses Acquired

     Financial statements of PIC Wisconsin and pro forma financial information
are not required to be filed with this report under Rule 3.05(b)(2) and Rule
