See Invested Assets for furtherinformation.
AIG generates income tax credits as a result of investing insynthetic fuel production (synfuels) related to the partnershipincome (loss) shown in the above table and records those benefits separately from segment operating results in its consoli-dated provision for income taxes.
The amounts of those incometax credits were $84 million，$127 million and $203 million for2007,2006 and 2005,respectively.
These tax credits will nolonger be generated after December 31,2007.
Synfuel productionhas ceased and the investments have been fully written off as ofDecember 31,2007.2006 and 2005 Comparison Net investment income increased 7 percent in 2006 compared to2005 as income from fixed maturities,equity securities and mortgage and other loans income rose as the underlying investedasset base grew.
Net investment income in 2006 also includedthe out of period increase relating to ucITS of $240 million.
American International Group, Inc.  and Subsidiaries majority of the losses would be incurred in the first year.
Themodeled losses calculated were based on 2006 policy datarepresenting approximately 92 percent of AIG's individual life,group life and credit life books of business, net of reinsurance.
This estimate does not include claims that could be made underother policies,such as business interruption or general liabilitypolicies,and does not reflect estimates for losses resulting fromdisruption of AlG's own business operations or asset losses thatmay arise out of such a pandemic.
The model used to generatethis estimate has only recently been developed.
The reasonable-ness of the model and its underlying assumptions cannot readilybe verified by reference to comparable historical events.
As are sult,AlG's actual losses from a pandemic influenza outbreakare likely to vary significantly from those predicted by the model.
Financial Services AIG's Financial Services subsidiaries engage in diversified activi-ties including aircraft and equipment leasing, capital markets,consumer finance and insurance premium finance.
Capital Markets The Capital Markets operations of AlG are conducted primarilythrough AIGFP, which engages as principal in standard and customized interest rate, currency,equity,commodity, energy andcredit products with top-tier corporations, financial institutions,governments，agencies，institutional investors and high-net-worthindividuals throughout the world.
The senior management of AlG defines the policies andestablishes general operating parameters for Capital Marketsoperations.
AIG's senior management has established variousoversight committees to monitor on an ongoing basis the variousfinancial market，operational and credit risk attendant to theCapital Markets operations.
The senior management of AIGFPreports the results of its operations to and reviews futurestrategies with AIG's senior manage ment.
AIGFP actively manages its exposures to limit potential eco-nomic losses,while maximizing the rewards afforded by thesebusiness opportunities even though some products or derivativesmay result in operating income volatility.
lIn doing so,AIGFPmustcontinually manage a variety of exposures including credit,market,liq uidity, operational and legal risks.
Derivative Transactions A counterparty may default on any obligation to AIG,including aderivative contract.
Credit risk is a consequence of extending credit and/or carrying trading and invesstment positions.
Credit riskexists for a derivative contract when that contract has a positive fair value to AIG.
The maximum potential exposure will increase ordecrease during the life of the derivative commitments as a  function of maturity and market conditions.

Transactions which fall outside these pre-establishedguidelines require the specific approval of the CRC.

relating to its outstanding financial derivative transactions.
AIGFPrequires credit enhancements in connection with specific transac-tions based on,among other things, the creditworthiness of thecounterparties,and the transaction's size and maturity.
Further-more,AIGFP generally seeks to enter into agreements that havethe benefit of set-off and close-out netting provisions.
Theseprovisions provide that, in the case of an early termination of atransaction,AIGFP can setoff its receivables from a counterpartyagainst its payables to the same counterparty arising out of allcovered transactions.
As a result, where a legally enforce ablenetting agreement exists, the fair value of the transaction with thecounterparty represents the net sum of estimated positive fairvalues.
The fair value of AIGFP's interest rate, currency, commod-ity and equity swaps，options，swaptions, and forward commit-ments,futures, and forward contracts approximated $17.13 billion at December 31,2007 and $19.61 billion at December 31，2006.
Where applicable，these amounts have beendetermined in accordance with the respective master netting agreements.
AIGFP evaluates the counterparty credit quality by reference toratings from rating agencies or,where such ratings are not available,by internal analysis consistent with the risk ratingpolicies of the CRC.
In addition,AIGFP's credit approval processinvolves pre-set counterparty and country credit exposure limitsand, for particularly credit-intensive transactions,requires approvalfrom the CRC.
AIG estimates that the average credit rating of Capital Markets derivatives counterparties, measured by referenceto the fair value of its derivative portfolio as a whole, is equivalentto the AA rating category.
At December 31, 2007 and 2006, the fair value of Capital Markets derivatives portfolios by counterparty credit rating was as follows:
