Citigroup (C)

Trading Account Assets — Trading Securities and Trading Loans

When available, the Company uses quoted market prices to determine the fair value of trading securities; such items are classified in Level 1 of the fair-value hierarchy. Examples include some government securities and exchange-traded equity securities.

For bonds and secondary market loans traded over the counter, the Company generally determines fair value utilizing internal valuation techniques. Fair values from internal valuation techniques are verified, where possible, to prices obtained from independent vendors. Vendors compile prices from various sources and may apply matrix pricing for similar bonds or loans where no price is observable. If available, the Company may also use quoted prices for recent trading activity of assets with similar characteristics to the bond or loan being valued. Trading securities and loans priced using such methods are generally classified as Level 2. However, when less liquidity exists for a security or loan, a quoted price is stale, or prices from independent sources vary, a loan or security is generally classified as Level 3.

Where the Company’s principal market for a portfolio of loans is the securitization market, the Company uses the securitization price to determine the fair value of the portfolio. The securitization price is determined from the assumed proceeds of a hypothetical securitization in the current market, adjusted for transformation costs (i.e., direct costs other than transaction costs) and securitization uncertainties such as market conditions and liquidity. As a result of the severe reduction in the level of activity in the securitization markets in the second half of 2007, observable securitization prices for directly comparable portfolios of loans have not been readily available. Therefore, such portfolios of loans are generally classified within Level 3 of the fair value hierarchy.
