Calculate UK government index linked bond (Index-linked Gilts) accrued interest
Introduced in release: 1.4 Component: Non-US (developed mkts) Purpose:
Calculates the accrued interest for a UK government index-linked gilt. The gilts can take the form of a regular bond or odd first coupon bond with optional partial payments. It also returns adjusted first coupon values to be passed to other routines.
Special Considerations:
This routine takes into consideration partial payments in the first period.
This function has as one of its parameters ukgb_convention_flag, a flag which specifies the convention to use in performing the calculation. The flag allows for auto determination or specification of the convention. Please review the documentation of ukgb_convention_flag for details.
Alternatives:
If price and/or yield are required in addition to accrued interest, use the ukgi_py_ai routine instead of this routine. If price and/or yield, current yield, estimated Macaulay duration, estimated convexity, interest on interest, etc. are required in addition to accrued interest, use the ukgi_cfsrisk routine.
Notes:
This routine can optionally perform its calculations considering an input ex-dividend date. To calculate an ex-dividend date use the ukgb_exd routine.
In addition to accrued interest, other values are returned by the routine - see outputs in Parameter Definition section.
Results:
The accrued interest per 100 of maturity value is returned.
Error Conditions:
Returned values should be ignored for a non-zero status. See Errors.
