{"columns":[{"field":"Basis","width":139},{"field":"Day count basis","width":174}],"rows":[{"Basis":"0 or omitted","Day count basis":"US (NASD) 30/360"},{"Basis":"1","Day count basis":"Actual/Actual"},{"Basis":"2","Day count basis":"Actual/360"},{"Basis":"3","Day count basis":"Actual/365"},{"Basis":"4","Day count basis":"European 30/360"}]}

@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.

Return Type

int

Remarks

A settlement date occurs in the coupon period where the settlement date is greater than or equal to start date of the coupon period and less than the end date of the coupon period (as the end date of one period is the start date of the next period).

If the @Frequency is any number other than 1, 2, 4 or 12, COUPDAYSNC returns an error.

If @Basis < 0 or @Basis > 4, COUPDAYSNC returns an error.

If @Settlement > @Maturity, COUPDAYSNC returns an error.
