20. The accrued interest per 100 of par value for Bond G on the settlement date of 16 June 2014 is closest to: A. 0.46. B. 0.73. C. 0.92. 選B。 C is correct. The accrued interest per 100 of par value is closest to 0.92. The accrued interest is determined in the following manner: The accrued interest period is identified as 66/180. The number of days between 10 April 2014 and 16 June 2014 is 66 days based on the 30/360 day count convention. (This is 20 days remaining in April + 30 days in May + 16 days in June = 66 days total). The number of days between coupon periods is assumed to be 180 days using the 30/360 day convention. Accrued interest=t/T ×PMT where: t = number of days from the last coupon payment to the settlement date T = number of days in the coupon period t/T = fraction of the coupon period that has gone by since the last payment PMT = coupon payment per period Accrued interest=66/180×5.002=0.92 麻煩老師幫我講解一下，這題中，PMT=5.002是如何計(jì)算的？

An analyst has been asked to convert to a monthly periodicity. Under this conversion, the yield-to-maturity is closest to: A. 3.87%. B. 4.95%. C. 7.67%. 麻煩老師幫忙講解一下，我換了好幾個(gè)方法都算不到3個(gè)備選答案。謝謝啦。
25. For the issuer, a sinking fund arrangement is most similar to a: A. term maturity structure. B. serial maturity structure. C. bondholder put provision. 麻煩老師講解一下這方面的知識(shí)，全部翻譯出來，還是不懂選哪個(gè)？謝謝啦。
