A corporate bond with a 7.600 percent coupon has 15 years left to maturity. It has had a credit rating of BB and a yield to maturity of 9.9 percent. The firm has recently become more financially stable and the rating agency is upgrading the bonds to BBB. The new appropriate discount rate will be 8.8 percent. (Assume interest payments are semiannual.)

What will be the change in the percentage terms?

Note: Do not round intermediate calculations. Round your final answer to 2 decimal places.
