In the following segment discussions, various statistics and other key data the Company uses to evaluate its segments are presented. Sales statistics are used by the Company to measure the relative progress in its marketing efforts, but may or may not have an immediate impact on reported segment operating income. Sales data for traditional life insurance are based on annualized premiums, while universal life sales are based on annualized planned (target) premiums plus 6% amounts received in excess of target premiums. Sales of annuities are measured based on the amount of deposits received. Stable value contract sales are measured at the time that the funding commitment is made based on the amount of deposit to be received. Sales within the Asset Protection segment are generally based on the amount of single premium and fees received.
Commissions and other costs of acquiring traditional life and health insurance, credit insurance, universal life insurance, and investment products that vary with and are primarily related to the production of new business, have been deferred. Traditional life and health insurance acquisition costs are amortized over the premium-payment period of the related policies in proportion to the ratio of annual premium income to the present value of the total anticipated premium income. Credit insurance acquisition costs are being amortized in proportion to earned premium. Acquisition costs for universal life and investment products are amortized over the lives of the policies in relation to the present value of estimated gross profits before amortization.
The amortized cost and estimated market value of fixed maturities at December 31, 2005, by expected maturity, are shown as follows. Expected maturities are derived from rates of prepayment that may differ from actual rates of prepayment.

The Company uses the same accounting policies and procedures to measure segment operating income and assets as it uses to measure its consolidated net income and assets. Segment operating income is generally income before income tax excluding net realized investment gains and losses (net of the related amortization of DAC and participating income from real estate ventures), and the cumulative effect of change in accounting principle. Periodic settlements of derivatives associated with corporate debt and certain investments and annuity products are included in realized gains and losses but are considered part of operating income because the derivatives are used to mitigate risk in items affecting consolidated and segment operating income. Segment operating income represents the basis on which the performance of the Company’s business is internally assessed by management. Premiums and policy fees, other income, benefits and settlement expenses, and amortization of DAC are attributed directly to each operating segment. Net investment income is allocated based on directly related assets required for transacting the business of that segment. Realized investment gains (losses) and other operating expenses are allocated to the segments in a manner that most appropriately reflects the operations of that segment. Investments and other assets are allocated based on statutory policy liabilities, while DAC and goodwill are shown in the segments to which they are attributable.
The Company’s share of net costs related to employee benefit plans was approximately $6.3 million, $5.5 million, and $6.9 million, in 2005, 2004, and 2003 respectively.
