In finance, a day count convention determines how interest accrues over time for a variety of investments, including bonds, notes, loans, mortgages, medium-term notes, swaps, and forward rate agreements (FRAs). This determines the number of days between two coupon payments, thus calculating the amount transferred on payment dates and also the ...
Original issue discount. Original Issue Discount ( OID) is a type of interest that is not payable as it accrues. OID is normally created when a debt, usually a bond, is issued at a discount. In effect, selling a bond at a discount converts stated principal into a return on investment, or interest. The accurate determination of principal and ...
Duration (finance) In finance, the duration of a financial asset that consists of fixed cash flows, such as a bond, is the weighted average of the times until those fixed cash flows are received. When the price of an asset is considered as a function of yield, duration also measures the price sensitivity to yield, the rate of change of price ...
The present value formula is the core formula for the time value of money; each of the other formulas is derived from this formula. For example, the annuity formula is the sum of a series of present value calculations. The present value (PV) formula has four variables, each of which can be solved for by numerical methods:
Coupon (finance) In finance, a coupon is the interest payment received by a bondholder from the date of issuance until the date of maturity of a bond. [ 1] Coupons are normally described in terms of the "coupon rate", which is calculated by adding the sum of coupons paid per year and dividing it by the bond's face value. [ 2]
By definition of Stirling numbers of the second kind, the probability that exactly T draws are needed is (,)! By manipulating the generating function of the Stirling numbers, we can explicitly calculate all moments of T: ():= (,) = = In general, the k-th moment is ()!
Return period. A return period, also known as a recurrence interval or repeat interval, is an average time or an estimated average time between events such as earthquakes, floods, [ 1] landslides, [ 2] or river discharge flows to occur. It is a statistical measurement typically based on historic data over an extended period, and is used usually ...
A swap agreement in which one party makes payments based on a set rate, either fixed or variable, while the other party makes payments based on the return of an underlying asset, which includes both the income it generates and any capital gains. In total return swaps, the underlying asset, referred to as the reference asset, is usually an ...
