Vincent T. Donnelly, President and Chief Executive Officer commented, “We are pleased with our results in the first quarter of 2008, especially in relation to the current challenges in the insurance sector.  We have made continued progress in profitably growing our insurance business in an increasingly competitive environment, and are excited about the continuing robust growth and improved profitability of our fee-based business.”

Significant operating achievements at The PMA Insurance Group included:

·   For the first quarter, pre-tax operating income increased 25% to $13.6 million, compared to $10.9 million in the same period last year;

·   Direct premium production, excluding premium adjustments and fronting premiums, increased 2% to $146.6 million, compared to $143.4 million in the first quarter of 2007; and

·   The combined ratio improved to 94.5%, compared to 98.2% for the first quarter last year.

Mr. Donnelly continued, “As we continue to execute our strategy to grow our service business, we are pleased that revenues from our fee-based businesses increased $8.8 million to $16.7 million, which represented 14% of our total revenues in the first quarter of 2008, compared to 7% in the first quarter of 2007.  Organic growth at PMA Management Corp. was 16% in the quarter and Midlands’ profitability was in line with our expectations.  In April, we entered into an agreement to acquire Webster Risk Services, a Connecticut-based TPA with $6 million in annual revenues.  We expect to complete this transaction in the second quarter, and on an annual basis, we expect per share earnings to increase by two cents as a result of this acquisition.”

On April 1, 2008, the Company announced the execution of a definitive stock purchase agreement to sell its Run-off Operations.  PMA will continue to work with the buyer to deliver all of the required information to the regulators to obtain approval of the transaction.

Income from continuing operations included the following after-tax net realized gains:

Segment Operating Results

Operating income, which we define as net income under accounting principles generally accepted in the United States (GAAP) excluding net realized investment gains and results from discontinued operations, is the financial performance measure used by our management and Board of Directors to evaluate and assess the results of our businesses.  Net realized investment activity is excluded 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 does not replace net income as the GAAP measure of our consolidated results of operations.

The following is a reconciliation of our operating results to GAAP net income.

1)   Effective in the fourth quarter of 2007, the Company reported the results of its former Run-off Operations segment as discontinued operations.

The PMA Insurance Group

The PMA Insurance Group reported pre-tax operating income of $13.6 million for the first quarter of 2008, compared to $10.9 million for the first quarter of 2007.

Direct premium production was up 2% for the first quarter, compared to the same period last year; however, direct premiums written for the first quarter of 2008 were down due to higher return premium adjustments of $13.3 million and a reduction in fronting premiums of $10.3 million.  Direct premiums written were $140.6 million for the first quarter of 2008, compared to $160.9 million for the first quarter of 2007.  The premium adjustments primarily related to favorable loss experience on loss-sensitive products where the insured shares in the underwriting result of the policy.  Fronting premiums were $8.1 million in the first quarter of 2008, compared to $18.4 million for the same period a year ago, which decreased due to the termination of our agreement with Midwest Insurance Companies (“Midwest”) in March 2008.  We continue to earn fees from the Midwest agreement and service the business previously written, but no additional business has been written or renewed since the termination date.  Excluding fronting business, we wrote $34.7 million of new business in the first quarter of 2008, compared to $39.1 million during the same period last year.  Pricing on our workers’ compensation rate-sensitive business declined 6% during the first three months of 2008, compared to a 5% decrease during the first three months of 2007.  Our renewal retention rate on existing workers’ compensation accounts for the first quarter was 85%, compared to 86% for the same period in 2007.

Net premiums written were $113.9 million in the first quarter of 2008, compared to $125.9 million in the same period last year.  Ceded premiums written decreased in the first quarter of 2008, compared to the first quarter of 2007.  The decline was primarily due to lower premiums ceded under the Midwest agreement, which was partially offset by an increase in the amount of workers’ compensation business sold to captive accounts, where a substantial portion of the direct premiums are ceded.

The combined ratio on a GAAP basis was 94.5% for the first three months of 2008, compared to 98.2% for the same period in 2007.  The improvement in the combined ratio for the first quarter of 2008, compared to the same quarter last year, was primarily the result of a lower expense ratio, and to  

3

a lesser extent, lower loss and LAE and policyholders’ dividend ratios.  Given the seasonality of our business, our first quarter combined ratios have historically been lower than the subsequent quarters and full year ratios.

The improved loss and LAE ratio was primarily due to favorable development in our loss-sensitive business which resulted in the retrospective premium adjustments.  Pricing changes coupled with payroll inflation for rate-sensitive workers’ compensation business were below overall estimated loss trends.  Our current accident year loss and LAE ratio remained consistent between periods as we continued to benefit in 2008 from changes in the type of workers’ compensation products selected by our insureds.  We estimated our medical cost inflation to be 6.5% in the first quarter of 2008, compared to our estimate of 8% in the first quarter of 2007.  The medical cost inflation rate has declined due to our enhanced network and managed care initiatives.  

The policyholders’ dividend ratio was lower in the first three months of 2008, compared to the same period last year.  The prior year period reflected better loss experience, which resulted in larger dividends on participating products where the policyholders may receive a dividend based, to a large extent, on their loss experience.

Fees earned under our fronting agreements reduced the first quarter expense ratio by 90 basis points, compared to 50 basis points for the same period in 2007.  Although our agreement with Midwest was terminated, we continue to earn fee income on this business until the underlying policies expire.  Our expense ratio also benefited from a reduction in premium-based state assessments.

Net investment income was $9.1 million in the first quarter of 2008, compared to $9.6 million in the prior year quarter.  The decrease was due primarily to a lower yield of approximately 20 basis points.

Fee-based Business

Our Fee-based Business reported pre-tax operating income of $2.2 million for the first quarter of 2008, compared to $793,000 for the same quarter last year.  The increase primarily related to the inclusion of Midlands Management Corporation’s (“Midlands”) results in 2008, which we acquired on October 1, 2007.

For the first quarter of 2008, total revenues increased to $16.7 million, up $8.8 million from the same period last year.  Revenues resulting from our acquisition of Midlands accounted for $7.6 million of this growth.  Revenues from PMA Management Corp. increased 16% in the first quarter of 2008, compared to the same period last year.  The total increase in revenues primarily reflected higher claims service revenues of $4.4 million and commission income of $4.3 million.

Corporate and Other

The Corporate and Other segment, which includes primarily corporate expenses and debt service, recorded net expenses of $5.0 million during the first quarter of 2008, compared to $5.1 million in the first quarter of 2007.

Discontinued Operations

Discontinued operations, formerly our Run-off Operations which consists of our former reinsurance and excess and surplus lines businesses, recorded an after-tax loss of $2.4 million for the first three months of 2008, compared to an after-tax loss of $1.5 million for the same period in 2007.  The first quarter loss in 2008 was the result of a $2.6 million after-tax charge for adverse loss development at

4

our discontinued operations, which contractually reduces the amount of cash and contingent consideration that we will receive at closing. The expected cash to be received has been reduced to $6 million and the value of the contingent consideration has been reduced to a face amount of $6 million.  We have recorded only the expected cash amount in our financials.

Financial Condition

Total assets were $2.6 billion as of March 31, 2008 and December 31, 2007.  Assets of discontinued operations represented 13% of total assets at March 31, 2008, compared to 15% at December 31, 2007.  Shareholders’ equity was $383.7 million as of March 31, 2008, compared to $378.6 million as of December 31, 2007.  Book value per share was $12.08 as of March 31, 2008, compared to $11.92 as of December 31, 2007.  The increases in shareholders’ equity and book value per share were primarily due to net income, which was partially offset by a change in the net unrealized position on our investment portfolio.  During the first three months of 2008, the unrealized position on our available for sale asset portfolio decreased by $1.6 million, or 5 cents per share.  The unrealized position on our portfolio decreased due to gains that we realized in the quarter which were partially offset by an increase as a result of lower market interest rates.  At March 31, 2008, we had $26.9 million in cash and short-term investments at the holding company.

The PMA Insurance Group had statutory capital and surplus of $343.6 million as of March 31, 2008, compared to $335.4 million as of December 31, 2007.  The PMA Insurance Group has the ability to pay $29.2 million in dividends during 2008 without the prior approval of the Pennsylvania Insurance Department.  The statutory capital and surplus of PMA Capital Insurance Company, PMA Capital Corporation’s wholly-owned run-off reinsurance subsidiary which is being reported as discontinued operations, was $41.1 million as of March 31, 2008, compared to $47.6 million as of December 31, 2007.
