Price (given yield) with more than one coupon period to redemption: PRI = R----V ⎛ ⎝ 1 + M-Y---⎠⎞ N - 1 + D-----S----C-E - 100 × -R--- × A--ME + N 100 × -R--- M K = 1 ⎝⎛1 + M-Y---⎠⎞ K - 1 + D-----S----C-E where: N =number of coupons payable between settlement date and redemption date (maturity date, call date, put date, etc.). (If this number contains a fraction, raise it to the next whole number; for example, 2.4 = 3) DSC =number of days from settlement date to next coupon date K =summation counter Note: The first term computes present value of the redemption amount, not including interest.
