1.Market rates are currently 5%. A $1,000 par corporate bond carries a coupon rate of 6%, pays coupons semiannually, and has ten coupon payments remaining to maturity. There are 90 days between settlement and the next coupon payment. Which of the following is closest to the dirty and clean prices of the bond？
　　A.$1,043.76, $1,013.76
　　B.$1,043.76, $1,028.76
　　C.$1,056.73, $1,041.73
　　D.$1,069.70, $1,054.70
　　Answer: C
　　The dirty price of the bond 90 days ago is calculated as N = 10; I/Y = 2.5; PMT = 30; FV = 1,000; CPT→PV = 1,043.76. Adjusting the PV for the fact that there are only 90 days until the receipt of the first coupon, then the dirty price now is .
