Answer is also not .500

Company A is an AAA-rated firm desiring to issue five-year FRNs. It finds that it can issue FRNs at six-month LIBOR + .220 percent or at three-month LIBOR + .220 percent. Given its asset structure, three-month LIBOR is the preferred index. Company B is an A-rated firm that also desires to issue five-year FRNs. It finds it can issue at six-month LIBOR + 1.0 percent or at three-month LIBOR +.720 percent. Given its asset structure, six-month LIBOR is the preferred index. Assume a notional principal of $15,000,000. Determine the quality spread differential (QSD). (Do not round intermediate calculations. Enter your answer as a percent rounded to 3 decimal places.) Quality spread differential 500.000 percent X 3 decimal places required
