1. A bond pays a 3.6 percent coupon, paid semiannually. The bond will mature on 9/30/2024, has a face value of $100, and has a clean price of $90. For the purposes of this question, a Treasury bond of the same maturity currently is priced at par and yields 2 percent (also semi-annual compounding convention here). Assume a settlement date of 10/12/2021, and assume that the bonds interest accrual follows the 30/360 (US) compounding convention.
