(ix) reduction in the value of the Company’s investment portfolio as a result of changes in interest rates and yields in the market as well as geopolitical conditions and the impact of political, regulatory, judicial, economic or financial events, including terrorism, affecting the market generally and companies in the Company’s investment portfolio specifically;
Following is management’s narrative analysis of the results of operations of the Company for the three years ended December 31, 2007. This discussion should be read in conjunction with the audited consolidated financial statements and related notes beginning on page of this report.
The primary segment profitability measure that management uses is pre-tax operating earnings, which is calculated by adjusting income from continuing operations before federal income taxes to exclude: (1) net realized investment gains and losses, except for periodic net amounts paid or received on interest rate swaps that do not qualify for hedge accounting treatment and net realized gains and losses related to securitizations; and (2) the adjustment to amortization of DAC related to net realized investment gains and losses.
The Company earns revenues and generates cash primarily from policy charges, life insurance premiums and net investment income. Policy charges include asset fees, which are earned primarily from separate account values generated from the sale of individual and group variable annuities and investment life insurance products; cost of insurance charges earned on universal life insurance products, which are assessed on the amount of insurance in force in excess of the related policyholder account value; administrative fees, which include fees charged per contract on a variety of the Company’s products and premium loads on universal life insurance products; and surrender fees, which are charged as a percentage of premiums withdrawn during a specified period for annuity and certain life insurance contracts. Net investment income includes earnings on investments supporting fixed annuities, the MTN program and certain life insurance products, and earnings on invested assets not allocated to product segments, all net of related investment expenses. Other income includes asset fees, administrative fees, commissions and other income earned by subsidiaries of the Company that provide administrative, marketing and distribution services.
Management makes decisions concerning the sale of invested assets based on a variety of market, business, tax and other factors. All realized investment gains and losses generated by these sales, charges related to other-than-temporary impairments of available-for-sale securities and other investments, and changes in valuation allowances on mortgage loans on real estate are reported in net realized investment gains and losses. Also included are changes in the fair values of derivatives qualifying as fair value hedges and the related changes in the fair values of hedged items; the ineffective, or excluded, portion of cash flow hedges; changes in the fair values of derivatives that do not qualify for hedge accounting treatment; and periodic net amounts paid or received on interest rate swaps that do not qualify for hedge accounting treatment.
In addition to the comprehensive annual study of assumptions, management evaluates the appropriateness of the individual variable annuity DAC balance quarterly within pre-set parameters. These parameters are designed to appropriately reflect the Company’s long-term expectations with respect to individual variable annuity contracts while also evaluating the potential impact of short-term experience on the Company’s recorded individual variable annuity DAC balance. If the recorded balance of individual variable annuity DAC falls outside of these parameters for a prescribed time period, or if the recorded balance falls outside of these parameters and management determines it is not reasonably possible to get back within the parameters during this time period, assumptions are required to be unlocked, and DAC is recalculated using revised best estimate assumptions. When DAC assumptions are unlocked and revised, the Company continues to use the reversion to the mean process. See below for a discussion of current year assumption changes.
At the end of the second quarter of 2007, the Company determined as part of its analysis of DAC that the overall profitability of separate account products is expected to exceed previous estimates due to favorable financial market trends. Accordingly, the Company unlocked its DAC assumptions after completing a comprehensive review of assumptions used to project DAC and other related balances, including sales inducement assets, unearned revenue reserves, and guaranteed minimum death and income benefit reserves. This review covered all assumptions including expected separate account investment returns, lapse rates, mortality and expenses. Additionally, while the Company estimates that the overall profitability of its variable products has improved, it also expects the long-term net growth in separate account investment performance to moderate. As a result of its current analysis, including its evaluation of ongoing trends and expectations regarding financial market performance, the Company reduced its long-term net separate account growth rate assumption from approximately 8% to approximately 7%. The Company unlocked assumptions, as appropriate, for all investment products and variable universal life insurance products in order to remain consistent across product lines using revised assumptions which reflect the Company’s current best estimate of future events. Therefore, in the second quarter of 2007, the Company recorded a net increase in DAC and a benefit to DAC amortization and other related balances totaling $221.6 million pre-tax, which was reported in the following segments in the pre-tax amounts indicated: Individual Investments - $196.4 million; Retirement Plans - $10.5 million; and Individual Protection - $14.7 million.
During the second quarter of 2007, the Company added a new feature to its existing guaranteed minimum withdrawal benefit rider, Lifetime Income (L.inc). This new feature results in a substantial change in the existing contracts and, therefore, an extinguishment of the DAC associated with those contracts pursuant to Statement of Position 05-1, Accounting by Insurance Enterprises for Deferred Acquisition Costs in Connection with Modifications or Exchanges of Insurance Contracts. As a result, existing DAC and other related balances were eliminated resulting in a $135.0 million pre-tax charge.
The Company recorded net realized investment losses in 2007 compared to net gains in 2006 primarily due to a $99.3 million increase in impairment charges driven by challenging conditions in the credit markets. In addition, the Company recorded higher losses on living benefit embedded derivatives, net of economic hedging activity, primarily as a result of increased volatility in market returns. See Part II,
