Use Of Estimates

UseOfEstimates

<div>Use of EstimatesThe preparation of financial statements in accordance with GAAP requires the application of accounting policies that often involve a significant degree of judgment. Accounting policies that we believe are most dependent on the application of estimates and assumptions are considered our critical accounting estimates and are related to the determination of:<ul style='margin-top:0pt;' ><li style='text-align:left;margin-top:0pt;margin-bottom:3pt;' >liability for unpaid losses and loss adjustment expenses (loss reserves);</li><li style='text-align:left;margin-top:0pt;margin-bottom:3pt;' >reinsurance assets;</li><li style='text-align:left;margin-top:0pt;margin-bottom:3pt;' >valuation of future policy benefit liabilities and timing and extent of loss recognition;</li><li style='text-align:left;margin-top:0pt;margin-bottom:3pt;' >valuation of liabilities for guaranteed benefit features of variable annuity products;</li><li style='text-align:left;margin-top:0pt;margin-bottom:3pt;' >estimated gross profits to value deferred policy acquisition costs for investment-oriented products;</li><li style='text-align:left;margin-top:0pt;margin-bottom:3pt;' >impairment charges, including other-than-temporary impairments on available for sale securities, impairments on other invested assets, including investments in life settlements, and goodwill impairment;</li><li style='text-align:left;margin-top:0pt;margin-bottom:3pt;' >allowances for loan losses;</li><li style='text-align:left;margin-top:0pt;margin-bottom:3pt;' >liability for legal contingencies; </li><li style='text-align:left;margin-top:0pt;margin-bottom:3pt;' >fair value measurements of certain financial assets and liabilities; and</li><li style='text-align:left;margin-top:0pt;margin-bottom:3pt;' >income tax assets and liabilities, including recoverability of our net deferred tax asset and the predictability of future tax operating profitability of the character necessary to realize the net deferred tax asset and provisional estimates associated with the Tax Act.</li></ul>These accounting estimates require the use of assumptions about matters, some of which are highly uncertain at the time of estimation. To the extent actual experience differs from the assumptions used, our consolidated financial condition, results of operations and cash flows could be materially affected.</div>

Deferred Policy Acquisition Costs Text Block1

DeferredPolicyAcquisitionCostsTextBlock1

<div>9. Deferred Policy Acquisition CostsDeferred policy acquisition costs (DAC) represent those costs that are incremental and directly related to the successful acquisition of new or renewal of existing insurance contracts. We defer incremental costs that result directly from, and are essential to, the acquisition or renewal of an insurance contract. Such deferred policy acquisition costs generally include agent or broker commissions and bonuses, premium taxes, and medical and inspection fees that would not have been incurred if the insurance contract had not been acquired or renewed. Each cost is analyzed to assess whether it is fully deferrable. We partially defer costs, including certain commissions, when we do not believe that the entire cost is directly related to the acquisition or renewal of insurance contracts.We also defer a portion of employee total compensation and payroll-related fringe benefits directly related to time spent performing specific acquisition or renewal activities, including costs associated with the time spent on underwriting, policy issuance and processing, and sales force contract selling. The amounts deferred are derived based on successful efforts for each distribution channel and/or cost center from which the cost originates.Short-duration insurance contracts: Policy acquisition costs are deferred and amortized over the period in which the related premiums written are earned, generally 12 months. DAC is grouped consistent with the manner in which the insurance contracts are acquired, serviced and measured for profitability and is reviewed for recoverability based on the profitability of the underlying insurance contracts. Investment income is anticipated in assessing the recoverability of DAC. We assess the recoverability of DAC on an annual basis or more frequently if circumstances indicate an impairment may have occurred. This assessment is performed by comparing recorded net unearned premiums and anticipated investment income on in-force business to the sum of expected losses and loss adjustment expenses incurred, unamortized DAC and maintenance costs. If the sum of these costs exceeds the amount of recorded net unearned premiums and anticipated investment income, the excess is recognized as an offset against the asset established for DAC. This offset is referred to as a premium deficiency charge. Increases in expected losses and loss adjustment expenses incurred can have a significant impact on the likelihood and amount of a premium deficiency charge.Long-duration insurance contracts: Policy acquisition costs for participating life, traditional life and accident and health insurance products are generally deferred and amortized, with interest, over the premium paying period. The assumptions used to calculate the benefit liabilities and DAC for these traditional products are set when a policy is issued and do not change with changes in actual experience, unless a loss recognition event occurs. These “locked-in” assumptions include mortality, morbidity, persistency, maintenance expenses and investment returns, and include margins for adverse deviation to reflect uncertainty given that actual experience might deviate from these assumptions. A loss recognition event occurs when there is a shortfall between the carrying amount of future policy benefit liabilities, net of DAC, and what the future policy benefit liabilities, net of DAC, would be when applying updated current assumptions. When we determine a loss recognition event has occurred, we first reduce any DAC related to that block of business through amortization of acquisition expense, and after DAC is depleted, we record additional liabilities through a charge to Policyholder benefits and losses incurred. Groupings for loss recognition testing are consistent with our manner of acquiring, servicing and measuring the profitability of the business and applied by product groupings. We perform separate loss recognition tests for traditional life products, payout annuities and long-term care products. Once loss recognition has been recorded for a block of business, the old assumption set is replaced and the assumption set used for the loss recognition would then be subject to the lock-in principle.Investment-oriented contracts: Policy acquisition costs and policy issuance costs related to universal life and investment-type products (collectively, investment-oriented products) are deferred and amortized, with interest, in relation to the incidence of estimated gross profits to be realized over the estimated lives of the contracts. Estimated gross profits include net investment income and spreads, net realized capital gains and losses, fees, surrender charges, expenses, and mortality gains and losses. In each reporting period, current period amortization expense is adjusted to reflect actual gross profits. If estimated gross profits change significantly, DAC is recalculated using the new assumptions, and any resulting adjustment is included in income. If the new assumptions indicate that future estimated gross profits are higher than previously estimated, DAC will be increased resulting in a decrease in amortization expense and increase in income in the current period; if future estimated gross profits are lower than previously estimated, DAC will be decreased resulting in an increase in amortization expense and decrease in income in the current period. Updating such assumptions may result in acceleration of amortization in some products and deceleration of amortization in other products. DAC is grouped consistent with the manner in which the insurance contracts are acquired, serviced and measured for profitability and is reviewed for recoverability based on the current and projected future profitability of the underlying insurance contracts.To estimate future estimated gross profits for variable annuity products, a long-term annual asset growth assumption is applied to determine the future growth in assets and related asset-based fees. In determining the asset growth rate, the effect of short-term fluctuations in the equity markets is partially mitigated through the use of a “reversion to the mean” methodology whereby short-term asset growth above or below long-term annual rate assumptions impacts the growth assumption applied to the five-year period subsequent to the current balance sheet date. The reversion to the mean methodology allows us to maintain our long-term growth assumptions, while also giving consideration to the effect of actual investment performance. When actual performance significantly deviates from the annual long-term growth assumption, as evidenced by growth assumptions in the five-year reversion to the mean period falling below a certain rate (floor) or above a certain rate (cap) for a sustained period, judgment may be applied to revise or “unlock” the growth rate assumptions to be used for both the five-year reversion to the mean period as well as the long-term annual growth assumption applied to subsequent periods. Shadow DAC and Shadow Loss Recognition: DAC related to investment-oriented products is also adjusted to reflect the effect of unrealized gains or losses on fixed maturity and equity securities available for sale on estimated gross profits, with related changes recognized through Other comprehensive income (shadow DAC). The adjustment is made at each balance sheet date, as if the securities had been sold at their stated aggregate fair value and the proceeds reinvested at current yields. Similarly, for long-duration traditional insurance contracts, if the assets supporting the liabilities are in a net unrealized gain position at the balance sheet date, loss recognition testing assumptions are updated to exclude such gains from future cash flows by reflecting the impact of reinvestment rates on future yields. If a future loss is anticipated under this basis, any additional shortfall indicated by loss recognition tests is recognized as a reduction in accumulated other comprehensive income (shadow loss recognition). Similar to other loss recognition on long-duration insurance contracts, such shortfall is first reflected as a reduction in DAC and secondly as an increase in liabilities for future policy benefits. The change in these adjustments, net of tax, is included with the change in net unrealized appreciation of investments that is credited or charged directly to Other comprehensive income.Internal Replacements of Long-duration and Investment-oriented Products:  For some products, policyholders can elect to modify product benefits, features, rights or coverages by exchanging a contract for a new contract or by amendment, endorsement, or rider to a contract, or by the election of a feature or coverage within a contract. These transactions are known as internal replacements. If the modification does not substantially change the contract, we do not change the accounting and amortization of existing DAC and related actuarial balances. If an internal replacement represents a substantial change, the original contract is considered to be extinguished and any related DAC or other policy balances are charged or credited to income, and any new deferrable costs associated with the replacement contract are deferred.Value of Business Acquired (VOBA) is determined at the time of acquisition and is reported in the Consolidated Balance Sheets with DAC. This value is based on the present value of future pre-tax profits discounted at yields applicable at the time of purchase. For participating life, traditional life and accident and health insurance products, VOBA is amortized over the life of the business in a manner similar to that for DAC based on the assumptions at purchase. For investment-oriented products, VOBA is amortized in relation to estimated gross profits and adjusted for the effect of unrealized gains or losses on fixed maturity and equity securities available for sale in a manner similar to DAC.The following table presents a rollforward of DAC and VOBA:</div><div><table style='border-collapse:collapse;' ><tr style='height:12pt;' ><td

of $1.3 billion, $842 million, and $583 million at December 31, 2017, 2016 and 2015, respectively, related to the effect of net unrealized gains and losses on available for sale securities (shadow DAC).The percentage of the unamortized balance of VOBA at December 31, 2017 expected to be amortized in 2018 through 2022 by year is: 8.4 percent, 7.8 percent, 7.2 percent, 6.1 percent and 5.9 percent, respectively, with 64.6 percent being amortized after five years. These projections are based on current estimates for investment income and spreads, persistency, mortality and morbidity assumptions.DAC, VOBA and SIA for insurance-oriented and investment-oriented products are reviewed for recoverability, which involves estimating the future profitability of current business. This review involves significant management judgment. If actual future profitability is substantially lower than estimated, AIG’s DAC, VOBA and SIA may be subject to an impairment charge and AIG’s results of operations could be significantly affected in future periods.</div>
