Critical Accounting Estimates

We prepare our financial statements in accordance with GAAP. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect amounts reported in our financial statements and accompanying notes. Estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed in our financial statements.

The accounting estimates deemed to be most critical to our results of operations and financial condition are those related to reserves for policy and contract benefits, deferred acquisition costs, valuation of investments, pension and postretirement benefit plans, and income taxes. There have been no significant changes in our critical accounting estimates during the first quarter of 2009.

For additional information concerning our accounting policies and critical accounting estimates, see Note 1 of the “Notes to Consolidated Financial Statements” in Part II, Item 8 and “Critical Accounting Estimates” in Part II, Item 7 of our annual report on Form 10-K for the year ended December 31, 2008.
