In March 2012, Daniela Motor Financing (DMF), offered some securities for sale to the public. Under the terms of the deal, DMF promised to repay the owner of one of these securities $600 in March 2042, but investors would receive nothing until then. Investors paid DMF $300 for each of these securities; so they gave up $300 in March 2012, for the promise of a $600 payment 30 years later. a. Assuming that you purchased the bond for $300, what rate of return would you earn if you held the bond for 30 years until it matured with a value $600 ? (Do not round intermediate calculations. Enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.) b. Suppose under the terms of the bond you could redeem the bond in 2022. DMF agreed to pay an annual interest rate of 1.2 percent until that date. How much would the bond be worth at that time? (Do not round intermediate calculations. Round your answer to 2 decimal places, e.g., 32.16.) c. In 2022, instead of cashing in the bond for its then current value, you decide to hold the bond until it matures in 2042 . What annual rate of return will you earn over the last 20 years? (Do not round intermediate calculations. Enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)
