SQL Server AIFACTOR_OFC Function
Updated 2023-10-06 11:55:35.177000
Description
Use the scalar-valued function AIFACTOR_OFC to calculate the Accrued Interest Factor for a bond during its odd first coupon period. AIFACTOR_OCF returns a decimal value which can then be multiplied by the face amount of the bond to return the monetary value of the accrued interest for the odd first period.
Syntax
SELECT [westclintech].[wct].[AIFACTOR_OFC] (
<@Basis, nvarchar(4000),>
,<@Rate, float,>
,<@IssueDate, datetime,>
,<@Settlement, datetime,>
,<@FirstInterestDate, datetime,>
,<@Frequency, int,>
,<@Holidays, nvarchar(max),>);
Arguments
@Basis
the day-count convention used in the calculation of the accrued coupon interest. @Basis is an expression of the character string data type category.

| 24 | Actual/AFB |
| 30 | BUS/252 non-end-of-month |
@IssueDate
the first accrual date for the bond. @IssueDate is an expression of type datetime or of a type that can be implicitly converted to datetime.
@Settlement
the settlement date of the transaction. @Settlement is an expression of type datetime or of a type that can be implicitly converted to datetime.
@FirstInterestDate
the first interest payment date for the bond. When the settlement date occurs on the first interest date, the factor returned will be for the entire first coupon period. @FirstInterestDate is an expression of type datetime or of a type that can be implicitly converted to datetime.
@Frequency
the number of coupon payments per year. For annual payments, @Frequency = 1; for semi-annual, @Frequency = 2; for quarterly, @Frequency = 4; for monthly, @Frequency = 12. @Frequency is an expression of type float or of a type that can be implicitly converted to float.
@Holidays
a comma separated string containing the holiday (non-business) dates to be used in the calculation of the number of business days. You can use the aggregate function NBD to create an appropriately formatted string.
Return Type
float
Remarks
@Settlement must be less than or equal to @FirstInterestDate.
@Settlement must be greater than or equal to @IssueDate.
If @Settlement = @IssueDate then the function returns zero.
For bonds where the settlement date is after the first interest date, use AIFACTOR or AIFACTOR_RPI.
For bonds where the settlement date is in an odd last coupon period, use AIFACTOR or AIFACOR_OLC.
For more information on accrual calculations, go to AIFACTOR.
Examples
In this example, we show the calculation of the accrued interest factor for the entire coupon period for all the supported day-count conventions. To keep the SELECT statement simple, we have put the holidays into a scalar variable up front. The holidays are only required for BUS/252 and BUS/252 NON-EOM day-count conventions.
