PRI
= dollar price per $100 par value
RV
= redemption value of the security per $100 par
value (
RV
= 100 except in those cases where
call or put features must be considered)
R
= annual interest rate (as a decimal; CPN _ 100)
M
= number of coupon periods per year standard
for the particular security involved (set to 1 or
2 in Bond worksheet)
DSR
= number of days from settlement date to
redemption date (maturity date, call date, put
