Description

Use the table-valued function OFCFACTORS to return the components used in the calculation of price and yield for a bond with an odd first coupon. OFCFACTORS supports odd first coupon bonds with up to 2 quasi-coupon periods.

Arguments

@FirstCoupon

the first coupon date of the security. The period from the issue date until the first coupon date defines the odd interest period. All subsequent coupon dates are assumed to occur at regular periodic intervals as defined by @Frequency. @First_coupon is an expression that returns a datetime or smalldatetime value, or a character string in date format.

@Basis

is the type of day count to use. @Basis is an expression of the character string data type category.

@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.

@Rate

the security’s annual coupon rate. @Rate is an expression of type float or of a type that can be implicitly converted to float.

@Yield

the security’s annual yield. @Yld is an expression of type float or of a type that can be implicitly converted to float.

@Redemption

the security’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. ### @Issue the issue date of the security; the date from which the security starts accruing interest. @Issue is an expression that returns a datetime or smalldatetime value, or a character string in date format.

@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.

@Price

the price of the bond. @Price is an expression of type float or of a type that can be implicitly converted to float.

Remarks

If @Settlement is NULL then @Settlement = GETDATE().

If @Rate is NULL then @Rate = 0.

If @Redemption is NULL then @Redemption = 100.

If @Frequency is NULL then @Frequency = 2.

If @Basis is NULL then @Basis = 0.

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 OFCFACTORS returns an error.

If @Basis invalid (see above list), OFCFACTORS returns an error.

If @Maturity is NULL then an error is returned.

If @Issue is NULL then an error is returned.

If @FirstCoupon is NULL then an error is returned.

If @Settlement >= @FirstCoupon then nothing is returned.

The first quasi-coupon period is always the quasi-coupon period in which the issue date occurs.

The previous coupon date for the first quasi-coupon period is calculated using @Frequency, @Basis, and @Maturity. This is the value returned in quasistart.

If there is only one quasi-coupon period then quasicoup is NULL. Otherwise the previous coupon date for the second quasi-coupon period is calculated using @Frequency, @Basis, and @Maturity.

If there are 2 quasi-coupon periods then DFC2 = NLF2.

Examples

This bond has an odd short first coupon (meaning that the first coupon period is shorter than a normal coupon period) and settles on the issue date.
