Operational risk
The risk to the bank that errors made in the course of conducting its business will result in losses.

(1) A contract that gives its holder the right, but not the obligation, to buy or sell an underling security, commodity, or currency before a certain date. Options are often used in hedging. Put options give the holder the right to sell the underlying security, commodity, or currency at the strike price. Call options give the holder the right to buy the underlying security, commodity or currency at the strike price.

(2) A provision in a financial contract that gives one party to the contract one or more rights to change the maturity, the principal amount, the interest rate, or other contract term. In loans, the most common form of option risk arises from a borrower’s right to prepay. In securities, the most common form of option risk arises from an issuer’s right to call the security. See embedded option.

Option-adjusted duration
A duration measure that does allow for changes in cash flows as yields change A variation of effective or empirical duration. Option adjusted duration incorporates the expected duration-shortening effect of an issuer's embedded call provision. It is also called adjusted duration.

Option-adjusted spread (OAS)
(1) A measurement of the return provided to an investor from a financial instrument that is either an option or that includes an option. The option-adjusted spread calculations break up a security into separate cash flows. Each of those cash flows is discounted at a unique discount rate appropriate for its maturity. The discount rates are obtained from a benchmark yield curve. The benchmark yield curve is simply the currently available (spot) yields for risk-free investments of various maturities. Since U.S. Treasury obligations are not considered to have any credit risk, Treasury rates are used. OAS is not quoted as a yield. Instead, it is quoted as a difference, or spread, in basis points.

(2) A valuation technique for valuing financial instruments, portfolios of financial instruments, or financial institutions with options. This tool is one component used in the Office of Thrift Supervision net portfolio value model for modeling the interest rate risk in complex financial instruments. This methodology is also used by high-end commercial interest rate risk analysis models.

Option risk
The risk that a change in prevailing interest rates will lead to an adverse impact on earnings or capital caused by changes in the timing of cash flows from investments.

Option risk usually arises when a change in prevailing interest rates prompts the option holder to exercise the option. See option.

Option writer

Original face or original face value

Original-issue discount (OID)
The amount of the difference between the par or redemption price and the price of the security at the time of its original issue. Issuers can issue securities with OID as an alternative to making periodic interest payments as a means of compensating investors. Zero coupon notes, strips, discount notes, and banker’s acceptances are examples of investment types with OID. For those instruments, the return provided to the investor comes in the form of a discount. OID should not be confused with the discounts that investors may pay for either coupon-bearing instruments or discount instruments resulting from a change in prevailing rates subsequent to the issuance of a security. OID is subject to different income tax treatment than discounts resulting from changes in market prices.

See over the counter.

Over collateralization
