isma_ex_ai (routine)

Calculates accrued interest for an ISMA bond - cum or ex dividend

Introduced in release: 1.0
Component: Non-US (developed mkts)
Superceded By: isma_99_exai

Purpose: Calculates the accrued interest, with the option of considering an ex-dividend date, for an ISMA regular bond, odd first coupon bond, odd last coupon bond, and odd first and last coupon bond.

Special Considerations: ISMA rules call for all bonds to be traded cum dividend (without an ex-dividend provision). This routine performs ISMA methodology calculations including an ex-dividend provision.

Notes: The ex-dividend status can be determined using either the trade or settlement date. When the bond is trading ex-dividend the accrued interest will be negative. In addition to accrued interest, other values are returned by the routine - see outputs in Parameter Definition section.

Results: All results are calculated using industry standard rules. The routine returns the accrued interest per 100 of maturity value accurate to as many places as supported by a double precision value.

Error Conditions: Returned values should be ignored for a non-zero status. See Errors.
