The first coupon date which follows the settlement date.

Description

Function imsl_next_coupon_date computes the next coupon date after the settlement date. For a good discussion on day count basis, see SIA Standard Securities Calculation Methods 1993, vol 1, pages 17-35.

Example

In this example, imsl_next_coupon_date computes the next coupon date of a bond with the settlement date of November 11, 1996, and the maturity date of March 1, 2009, using the Actual/365 day count method.

 

#include <stdio.h>

#include <imsl.h>

 

int main()

{

struct tm settlement, maturity, date;

char* month[] = { "January", "February", "March", "April", "May",

"June", "July", "August", "September",

"October", "November", "December" };

int frequency = IMSL_SEMIANNUAL;

int basis = IMSL_DAY_CNT_BASIS_ACTUAL365;

 

settlement.tm_year = 96;

settlement.tm_mon = 10;

settlement.tm_mday = 11;

 

maturity.tm_year = 109;

maturity.tm_mon = 2;

maturity.tm_mday = 1;

 

date = imsl_next_coupon_date (settlement, maturity, frequency, basis);

printf ("The next coupon date after the settlement date ");

printf ("is %s %d, %d.\n", month[date.tm_mon], date.tm_mday,

date.tm_year+1900);

}

Output

 

The next coupon date after the settlement date is March 1, 1997.
