The “end-of-month” convention is used to determine coupon dates in the
following exceptional situations. (This affects calculations for YLD%,
PRICE, and ACCRU.)
If the maturity date falls on the last day of the month, then the coupon
payments will also fall on the last day of the month. For example, a
semiannual bond that matures on September 30 will have coupon
payment dates on March 31 and September 30.
If the maturity date of a semiannual bond falls on August 29 or 30,
then the February coupon payment dates will fall on the last day of
February (28, or 29 in leap years).
