Delphi’s net income attributable to shareholders in the first half of 2010 was $74.6 million or $1.34 per share, compared to net income attributable to shareholders in the first half of 2009 of $61.5 million or $1.25 per share.

Robert Rosenkranz, Chairman and Chief Executive Officer, commented, “Delphi achieved excellent financial results in the second quarter, with shareholders’ equity and book value per share continuing to increase to all-time highs. We were pleased with operating earnings in the quarter, which were driven by attractive underwriting profit margins in all of our insurance businesses. Reliance Standard achieved 15% growth in production over last year’s second quarter while maintaining pricing and underwriting discipline. Safety National continued to increase our market leadership position in the excess workers’ compensation market and achieved notable growth in assumed workers’ compensation reinsurance. Preliminary results for the July renewal period in excess workers’ compensation were encouraging.”

Delphi’s net investment income in the second quarter of 2010 was $78.2 million compared to $92.0 million in the second quarter of 2009. Invested assets at June 30, 2010 were $6.1 billion compared to $5.2 billion at June 30, 2009. The tax equivalent yield on the Company’s investment portfolio in the second quarter of 2010 was 5.6% compared to 7.9% in the second quarter of 2009. Shareholders’ equity at June 30, 2010 was $1.499 billion, up from $1.359 billion at December 31, 2009 and $1.052 billion at June 30, 2009. Diluted book value per share was $26.74 at June 30, 2010, compared with $24.42 at December 31, 2009 and $20.35 at June 30, 2009.

Mr. Rosenkranz added, “Investment income was in line with our expectations, a gratifying outcome in a volatile quarter, although below last year’s second quarter results. The results for last year’s quarter were boosted by exceptionally high returns from our alternative investments portfolio. We continued to hold about 6% of invested assets in short-term investments, as it has been challenging to find appealing investments when interest rates are low and spreads tight. Realized investment losses from other-than-temporary impairments continued to decline, a further indication that the worst of the financial crisis is behind us. Also, Delphi continued to take action to strengthen our balance sheet and capital position in the second quarter. The partial call of our 8.00% Senior Notes, which was finalized in July, together with additional note repurchases, resulted in the retirement of $25 million of these notes. At the end of the second quarter our debt-to-capital ratio was 19%, with no short-term debt and holding company financial resources at a comfortable $96 million.”

(1) Operating earnings, which is a non-GAAP financial measure, consist of net income attributable to shareholders excluding after-tax realized investment gains and losses, losses on redemptions of senior notes and junior subordinated deferrable interest debentures and results from discontinued operations, as applicable. The Company believes that because these excluded items arise from events that are largely within management’s discretion and whose fluctuations can distort comparisons between periods, a measure excluding their impact is useful in analyzing the Company’s operating trends. Investment gains or losses are realized based on management’s decision to dispose of an investment, and investment losses are realized based on management’s judgment that a decline in the market value of an investment is other than temporary. Redemptions of senior notes and junior subordinated deferrable interest debentures occur based on management’s decision to effect these redemptions. Discontinued operations result from management’s decision to exit or sell a particular business. Thus, these excluded items are not reflective of the Company’s ongoing earnings capacity, and trends in the earnings of the Company’s underlying insurance operations can be more clearly identified without their effects. For these reasons, management uses the measure of operating earnings to assess performance and make operating plans and decisions, and the Company believes that analysts and investors typically utilize measures of this type as one element of their evaluations of insurers’ financial performance. However, gains or losses from the excluded items, particularly as to investments, can occur frequently and should not be considered as nonrecurring items. Further, operating earnings should not be considered a substitute for net income attributable to shareholders, the most directly comparable GAAP measure, as an indication of the Company’s overall financial performance and may not be calculated in the same manner as similarly titled captions in other companies’ financial statements. For reconciliations of the respective operating earnings amounts to the corresponding net income attributable to shareholders amounts for the indicated periods, see the table captioned “Non-GAAP Financial Measures — Reconciliation to GAAP” which follows. All per share amounts are on a diluted basis.

(2) Annualized operating return on beginning equity, which is a non-GAAP financial measure, is based on operating earnings, as defined in the preceding footnote (1) (rather than the most directly comparable GAAP measure, net income attributable to shareholders), divided by beginning shareholders’ equity. For the reasons that the Company believes that the calculation of this non-GAAP measure based upon operating earnings is useful, see such footnote. For reconciliations of the respective annualized operating return on equity amounts to the corresponding annualized net income return on equity amounts for the indicated periods, see the table captioned “Non-GAAP Financial Measures — Reconciliation to GAAP” which follows.
