# SQL Server ODDLPRICE function

ODDLPRICE

Updated: 30 June 2014

Use ODDLPRICE to calculate the price per 100 face value of a bond with an odd last coupon period. The formula for price when the settlement date is less than the last coupon date is:

Where

 C = 100 * coupon rate / frequency Y = yield / frequency RV = redemption value DSC = number of days from settlement to coupon N = the number of coupons between the settlement date and the last coupon date E = the number of days in the current coupon period A = C * accrued days / E NCL = the number of quasi-coupons from the last coupon date to the quasi-maturity date DLCi = the number of days from the previous coupon date to the lesser of the next coupon date and the maturity date in the ith quasi-coupon period NLLi = the normal length in days of the full ith quasi-coupon period in the odd last period LC = C *

The formula for price when the settlement date is greater than or equal to the last coupon date is:

Where

 C = 100 * coupon rate / frequency Y = yield / frequency RV = redemption value NCL = the number of quasi-coupons from the last coupon date to the quasi-maturity date DSCi = number of days from settlement date (or beginning of quasi-coupon period) to the next quasi-coupon within odd period (or to redemption date) for the ith quasi-coupon period Ai = number of accrued days for the ith quasi-coupon period within odd period counting forward from the last interest date before redemption DLCi = the number of days from the previous coupon date to the lesser of the next coupon date and the maturity date in the ith quasi-coupon period NLLi = the normal length in days of the full ith quasi-coupon period in the odd last period LC = C *

Arguments
@Settlement
the settlement date of the security. @Settlement is an expression that returns a datetime or smalldatetime value, or a character string in date format.
@Maturity
the maturity date of the security. @Maturity is an expression that returns a datetime or smalldatetime value, or a character string in date format.
@Last_interest
the last coupon date of the security prior to the maturity. The period from the last interest date until the maturity date defines the odd interest period. All previous coupon dates are assumed to occur at regular periodic intervals as defined by @Frequency. @Last_interest is an expression that returns a datetime or smalldatetime value, or a character string in date format.
@Rate
the securityâ€™s annual coupon rate. @Rate is an expression of type float or of a type that can be implicitly converted to float.
@Yld
the securityâ€™s annual yield. @Yld is an expression of type float or of a type that can be implicitly converted to float.
@Redemption
the securityâ€™s redemption value per 100 face value. @Redemption is an expression of type float or of a type that can be implicitly converted to float.
@Frequency
the number of coupon payments per year. For annual payments, @Frequency = 1; for semi-annual, @Frequency = 2; for quarterly, @Frequency = 4; for bimonthly @Frequency = 6; for monthly, @Frequency = 12. For bonds with @Basis = 'A/364' or 9, you can enter 364 for payments made every 52 weeks, 182 for payments made every 26 weeks, 91 for payments made every 13 weeks, 28 for payments made every 4 weeks, 14 for payments made every 2 weeks, and 7 for weekly payments. @Frequency is an expression of type float or of a type that can be implicitly converted to float.
@Basis
is the type of day count to use. @Basis is an expression of the character string data type category.

Remarks
Â·         If @Settlement is NULL then @Settlement = GETDATE().
Â·         If @Rate is NULL then @Rate = 0.
Â·         If @Yield is NULL then @Yield = 0.
Â·         If @Redemption is NULL then @Redemption = 100.
Â·         If @Frequency is NULL then @Frequency = 2.
Â·         If @Basis is NULL then @Basis = 0.
Â·         If @Frequency is any number other than 1, 2, 4, 6 or 12, or for @Basis = 'A/364' any number other than 1, 2, 4, 6, or 12 as well as 7, 14, 28, 91, 182, or 364 ODDLPRICE returns an error.
Â·         If @Basis is invalid (see above list), ODDLPRICE returns an error.
Â·         If @Maturity is NULL then an error is returned.
Â·         If @Last_interest is NULL then an error is returned.
Examples
