AMERICAN PHYSICIANS SERVICE GROUP, INC. REPORTS

THIRD QUARTER EARNINGS

AUSTIN, TX – (MARKET WIRE) – November 2, 2010 – American Physicians Service Group, Inc. (“APS”) (NASDAQ:  AMPH) today announced results for the quarter and nine months ended September 30, 2010.  For the three months ended September 30, 2010, revenues were $18.3 million compared to $19.9 million for the same period last year.  For the nine months ended September 30, 2010, revenues were $55.4 million compared to $55.8 million in the same period last year.  Net earnings for the third quarter were $4.9 million or $.71 per diluted share, compared to $6.4 million or $.92 per diluted share, in the same period last year. Net earnings for the first nine months were $15.6 million or $2.25 per diluted share, compared to $16.1 million or $2.28 per diluted share in the same period last year.  

Ken Shifrin, APS Chairman of the Board, stated, “On September 1, 2010 we announced our agreement to merge with ProAssurance Corporation for $32.50 cash per common share.  While this quarter’s earnings were excellent, they declined from the prior period due to non-recurring transaction related expenses of $1.5 million, including legal and other professional expenses, a fairness opinion, and certain compensation expenses.”

Tim LaFrey, President of APS, added, “A competitive environment spurred by the success of tort reform in Texas continues to put pressure on prices and thus premium revenue in our largest market. Conversely, tort reform benefits us with low claims frequency and our underwriting margin continues to be very favorable. On the investment side, recurring investment income is beginning to stabilize at a lower level as interest rates have little room to fall any further; likewise, the investment portfolio has stabilized, with increased capital gains and fewer impairments in 2010. We continue to emphasize safeguarding our capital in our investment decisions.”

Mr. Shifrin concluded, “Our management team is focused on completing the requirements of the merger in order to achieve a 2010 closing.  We look forward to communicating further with you as that event approaches.”

As a result of the proposed acquisition of APS by ProAssurance Corporation, the Company has elected to discontinue hosting its earnings conference call.

APS is an insurance services firm with subsidiaries and affiliates which provide medical malpractice insurance and related services for physicians and other healthcare providers.  APS is headquartered in Austin, Texas.

Non-GAAP Financial Measures

Operating Income is a “Non-GAAP” financial measure which is widely used in the insurance industry to evaluate the performance of underwriting operations. Operating Income excludes the after-tax effects of realized investment gains or losses and infrequent items that are not considered core to the underwriting performance of our insurance segment or the operating performance of our financial services segment, and we believe presents a more appropriate view of the performance of our core operations. We present this information to facilitate industry peer comparisons by investors and by outside industry analysts. While we believe disclosure of certain non-GAAP information is appropriate, you should not consider this information without also considering the information we present in accordance with GAAP.  The following table is a reconciliation of Net Income to Operating Income:
