【答案解析】No calculations are really necessary here since the MMY involves no compounding and a 360 - day year, the BEY requires compounding the quarterly HPR to a semiannual rate and doubling that rate, and the EAY requires compounding for the entire year based on a 365 - day year. A numerical example of these calculations based on a 90 - day holding period yield of 1.3% is: the equivalent money market yield is 1.3% x 360/90 = 5.20% , the bond equivalent yield is 2×

, which is two times the equivalent effective semiannual rate of return, and the effective annual yield is
