Occam Industrial Machines issued $160,000$ zero coupon bonds $5$ years ago. The bonds originally had $30$ years to maturity with a yield to maturity of $6\mathrm{.}3$ percent. Interest rates have recently decreased, and the bonds now have a yield to maturity of $5\mathrm{.}4$ percent. The bonds have a par value of $$2,000$ and semiannual compounding.
