Answer:
$1,101.58
Explanation:
Tenor: 30 times (15-year maturity * 2 for semiannual)
Coupon rate: 7.25% semiannual -> coupon received semiannual (PMT) = $1,000 * 7.25%/2 = $36.25
Face value (FV): $1,000
Yield To Date (YTD): 6.20% semiannual -> YTD per semiannual = 3.1% (=6.20%/2)
Bond’s price = present value of bond + present value of total coupon received semiannual
Present value of bond = FV/(1+ YTD) ^tenor = 1000/(1+3.1%)^30 = $400.1659
present value of total coupon received semiannual = 36.25/(1+3.1%)^30 + 36.25/(1+3.1%)^29+ ….. + 36.25/(1+3.1%)^1 = $701.4189
(we can use excel to calculate the PV of coupon received = PV(rate,tenor,-PMT) = PV(3.1%,30,-36.25) = 701.42)
⇒ Bond’s price = $400.1659+ $701.4189= $1,101.58
