NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS The following pro forma purchase accounting adjustments were undertaken to reflect the Company's investment in Symetra Financial. [a] INVESTMENT INCOME The Company paid $200.0 MILLION in cash for its investment in Symetra Financial. The Company estimates that it earned $3.0 MILLION and $6.0 MILLION for the periods ended June 30, 2004 and December 31, 2003, respectively, on such balances which were held in short-term investments. The yield of 3% approximates the Company's pre-tax yield on its short-term investment portfolio during the period. As a result, a Federal income tax benefit of $.8 MILLION and $1.7 MILLION, for the periods ended June 30, 2004 and December 31, 2003, respectively, were recorded for these transactions. [b] EXTRAORDINARY GAINS The Company paid $200.0 million for a 19% interest in the common stock of Symetra Financial, which has a fair value at the date of purchase of $200.0 million, and warrants to acquire 1,099,600 of the common shares of Symetra Financial, which has a fair value at the date of purchase of $36.5 million. As a result, the Company has recognized a pro forma gain of $36.5 million representing the excess of the fair value of assets acquired over the consideration paid for its interests in Symetra Financial. The Company has valued its warrants to acquire common shares of Symetra Financial using a five-year expected term with a risk-free interest rate commensurate with the term valued (3.8%) and using volatility of 30%. [c] EQUITY IN EARNINGS OF UNCONSOLIDATED AFFILIATES The Company recorded $20.0 MILLION and $35.4 MILLION representing the Company's ownership of approximately 19% in the net income of Symetra Financial for the periods ended June 30, 2004 and December 31, 2003, respectively. [d] EARNINGS PER COMMON SHARE In determining both basic and diluted earnings per Common Share before pro-forma adjustments, net income from continuing operations is reduced by $49.5 million to reflect an adjustment to the redemption value on the Company's convertible preference shares for the period ended December 31, 2003. In determining diluted earnings per Common Share before pro-forma adjustments, net income from continuing operations is further reduced by $.8 million and $2.5 million for the periods ended June 30, 2004 and December 31, 2003, respectively, resulting from outstanding options and warrants to acquire common shares of an unconsolidated affiliate of the Company. The basic earnings per Common Share computation is determined using the weighted average number of Common Shares outstanding during the period. The diluted earnings per Common Share computation is determined using the weighted average number of Common Shares and dilutive Common Share equivalents outstanding during the period.
