## Money market and other short term investments and deposits with fi nancial institutions 

The fair value of assets maturing within a year is assumed to be approximated by their carrying amount adjusted for credit risk where appropriate. Credit risk adjustments are based on market observable credit spreads if available, or management’s estimate if not market observable. 

## Free standing fi nancial derivatives 

Where quoted market prices are not available, other valuation techniques, such as option pricing or stochastic modeling, are applied. The valuation techniques incorporate all factors that a typical market participant would consider and are based on observable market data when available. Models are validated before they are used and calibrated to ensure that outputs reflect actual experience and comparable market prices. 

Fair values for exchange-traded derivatives, principally futures and certain options, are based on quoted market prices in active markets. Fair values for over-the-counter (OTC) derivative financial instruments represent amounts estimated to be received from or paid to a third party in settlement of these instruments. These derivatives are valued using pricing models based on the net present value of estimated future cash flows, directly observed prices from exchange-traded derivatives, other OTC trades, or external pricing services. Most valuations are derived from swap and volatility matrices, which are constructed for applicable indices and currencies using current market data from many industry standard sources. Option pricing is based on industry standard valuation models and current market levels, where applicable. The pricing of complex or illiquid instruments is based on internal models or an independent third party. For long-dated illiquid contracts, extrapolation methods are applied to observed market data in order to estimate inputs and assumptions that are not directly observable. To value OTC derivatives, management uses observed market information, other trades in the market and dealer prices. 

AEGON normally mitigates counterparty credit risk in derivative contracts by entering into collateral agreements where practical and in ISDA master netting agreements for each of the Group’s legal entities to facilitate AEGON’s right to offset credit risk exposure. In the event no collateral is held by AEGON or the counterparty, the fair value of derivatives is adjusted for credit risk based on market observable spreads. Changes in the fair value of derivatives attributable to changes in counterparty credit risk were not significant. 

## Derivatives embedded in insurance contracts including guarantees 

Certain guarantees for minimum benefits in insurance and investment contracts are carried at fair value. These guarantees include guaranteed minimum withdrawal benefits (GMWB) in the United States which are offered on some AEGON variable annuity products and are also assumed from a ceding company; minimum interest rate guarantees on insurance products offered in The Netherlands, including group pension and traditional products; Variable annuities sold in Europe; and guaranteed minimum accumulation benefits on segregated funds sold in Canada. 

The fair values of these guarantees are calculated as the present value of future expected payments to policyholders less the present value of assessed rider fees attributable to the guarantees. Given the complexity and long-term nature of these guarantees which are unlike instruments available in financial markets, their fair values are determined by using stochastic techniques under a variety of market return scenarios. A variety of factors are considered, including expected market rates of return, equity and interest rate volatility, credit spread, correlations of market returns, discount rates and actuarial assumptions. 

The expected returns are based on risk-free rates. The credit spread is set by using the credit default swap (CDS) spreads of a reference portfolio of life insurance companies (including AEGON), adjusted to reflect the subordination of senior debt holders at the holding company level to the position of policyholders at the operating company level (who have priority in payments to other creditors). Because CDS spreads for US life insurers differ significantly from that for European life insurers, AEGON’s assumptions are set by region to reflect these differences in the valuation of the guarantee embedded in the insurance contracts. 

For equity volatility, AEGON uses a term structure assumption with market-based implied volatility inputs for the first five years and a long-term forward rate assumption of 25% thereafter. The volume of observable option trading from which volatilities are derived generally declines as the contracts’ term increases, therefore, the volatility curve grades from implied volatilities for five years to the ultimate rate. The resulting volatility assumption in year 20 for the S&P 500 index (expressed as a spot rate) was 24.8% at December 31, 2010 and 25.3% at December 31, 2009. Correlations of market returns across underlying indices are based on historical market returns and their inter-relationships over a number of years preceding the valuation date.
