A 4-year government bond makes annual coupon payments of 4.5% and offers a yield of 2.5% annually compounded. Assume the face value is $1,000. Note: Do not round intermediate calculations. Enter your answers as a percent rounded to 2 decimal places.

1. Suppose that one year later, the bond still yields 2.5%. What return has the bondholder earned over the 12-month period?

2. Now suppose that the bond yields 1.5% at the end of the year. What return did the bondholder earn in this case?
