Description

Use the scalar function ODDLINT to calculate the accrued interest for a bond with an odd last coupon and a par value of 100.

Syntax

SELECT [westclintech].[wct].[ODDLINT](
  <@Settlement, datetime,>
 ,<@Maturity, datetime,>
 ,<@Last_coupon, datetime,>
 ,<@Rate, float,>
 ,<@Frequency, float,>
 ,<@Basis, nvarchar(4000),>);

Arguments

@Settlement

the settlement date of the security. @Settlement is an expression that returns a datetime value, or a character string in date format.

@Maturity

the maturity date of the security. @Maturity is an expression that returns a datetime value, or a character string in date format.

@Last_coupon

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_coupon is an expression that returns a datetime value, or a character string in date format.

@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.

@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.

16 , 'NL/ACT NON-EOM'	No Leap Year/ACT non-end-of-month
17 , 'NL/365 NON-EOM'	No Leap Year/365 non-end-of-month
18 , 'NL/360 NON-EOM'	No Leap Year/360 non-end-of-month

Return Type

float

Remarks

If @Settlement is NULL then an error is returned.

If @Rate is NULL then NULL is returned.

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 ODDLINT returns an error.

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

If @Maturity is NULL then an error is returned.

If @Last_coupon is NULL then an error is returned.

Examples

This is a bond with an odd short last coupon period where the settlement date is in the last period.

SELECT wct.ODDLINT(   '2014-10-01', --@Settlement
                      '2014-12-15', --@Maturity
                      '2014-09-15', --@Last_interest
                      0.0225,       --@Rate
                      2,            --@Frequency
                      1             --@Basis
