#include <imsl.h>

int imsl_days_to_next_coupon (struct tm settlement, struct tm maturity, int frequency, int basis)

Required Arguments

struct tm settlement   (Input)
The date on which payment is made to settle a trade. For a more detailed discussion on dates see the Usage Notes section of this chapter.

int basis   (Input)
The method for computing the number of days between two dates. It should be one of IMSL_DAY_CNT_BASIS_ACTUALACTUAL, IMSL_DAY_CNT_BASIS_NASD, IMSL_DAY_CNT_BASIS_ACTUAL360, IMSL_DAY_CNT_BASIS_ACTUAL365, or IMSL_DAY_CNT_BASIS_30E36.  For a more detailed discussion see the Usage Notes section of this chapter.

Return Value

The number of days starting with the settlement date and ending with the next coupon date.

Description

Function imsl_days_to_next_coupon computes the number of days from the settlement date to the next coupon date. For a good discussion on day count basis, see SIA Standard Securities Calculation Methods 1993, vol. 1, pp. 17-35.

Example

In this example, imsl_days_to_next_coupon computes the number of days from November 11, 1996, to the next coupon date of a bond with the maturity date of March 1, 2009, using the Actual/365 day count method.

 

#include <stdio.h>

#include "imsl.h"

 

void main()

{

  struct tm settlement, maturity;

  int frequency = IMSL_SEMIANNUAL;

  int basis = IMSL_DAY_CNT_BASIS_ACTUAL365;

  int days;

 

  settlement.tm_year = 96;

  settlement.tm_mon = 10;

  settlement.tm_mday = 11;

 

  maturity.tm_year = 109;

  maturity.tm_mon = 2;

  maturity.tm_mday = 1;

 

  days = imsl_days_to_next_coupon (settlement, maturity, frequency, basis);

  printf ("The number of days from the settlement date to ");

  printf ("the next coupon date is %d.\n", days);

}

Output

The number of days from the settlement date to the next coupon date is 110.
