Trading assets Trading Assets Total debt and equity financial instruments classified as (1) trading securities and (2) derivative assets. (1) The total of financial instruments that are bought and held principally for the purpose of selling them in the near term (thus held for only a short period of time) or for debt and equity securities formerly categorized as available-for-sale or held-to-maturity which the entity held as of the date it opted to account for such securities at fair value. An enterprise may also categorize such a security as trading without the intent to sell it in the near term assuming the decision to categorize the security as trading occurred at acquisition; this is the reason why the trading category of investments in debt and equity securities are bought and sold "principally" for sale in the near term. Transfers into and out of the trading category should be rare.

Fair Value, Assets and Liabilities Measured on Recurring Basis [Table] Level 1 Fair Value, Inputs, Level 1 [Member] Certificates of deposit, bankers’ acceptances and commercial paper Certificates Of Deposit Bankers Acceptances Commercial Paper [Member] Represents a combination of certificates of deposit, bankers’ acceptances and commercial paper. A certificate of deposit ("CD") is a short to medium-term, FDIC insured investment available at banks and savings and loan institutions. Customers agree to lend money to the institutions for a certain amount of time. In exchange for doing so, the customers is paid a predetermined rate of interest. Often, banks will charge a penalty fee if the money is withdrawn from the CD before it matures. A banker's acceptance, which often is used to finance shipments of goods to bank customers, is a short-term time draft that a bank (drawee) has agreed to pay at maturity by stamping "accepted" over the signature of an officer. When the bank accepts the draft, it guarantees its redemption at maturity, which makes the draft negotiable. In return for the guarantee, the party on whose behalf the bank accepts the draft (drawer) agrees to provide the bank with the necessary funds prior to maturity. The bank receives a fee for creating the acceptance. The drawer's outstanding debt to the bank is reported as an asset, and the bank's obligation is reported as a liability. Bankers' acceptances are similar to other short-term borrowed funds in that they can be effectively used for short-term liquidity needs by avoiding disbursing funds for short-term loans to bank customers. Commercial paper is an unsecured promissory note that provides creditworthy institutions, typically finance companies or holding companies of banks and savings institutions with short-term funds. Commercial paper is generally short-term (at most 270 days, but usually much less) and negotiable.

For derivative positions valued using internally developed models that use as their basis observable market parameters, an adjustment may be made to reflect the credit quality of each derivative counterparty to arrive at fair value. The adjustment may also take into account contractual factors designed to reduce the entity’s credit exposure to each counterparty, such as collateral and legal rights of offset. Debit Valuation Adjustment and Funding Valuation Adjustment Debit Valuation Adjustment and Funding Valuation Adjustment] [Member] Includes debit valuation adjustments ("DVA") to reflect the credit quality of the entity in the valuation of liabilities at fair value; and funding valuation adjustments ("FVA") to reflect the funding cost or benefit that a relevant market participant would consider in the transfer of an OTC derivative or structured note.
