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 Often, banks will charge a penalty fee if the money is withdrawn from the CD before it matures.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.

(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. Such financial instruments that are held as of the reporting date are measured at fair value with unrealized holding gains and losses (the difference between fair value and the previously reported carrying amount) included in earnings.
