This Exam FM sample reference tests Bond Valuation. Quarterly coupon is 87.50 and yield is 1.4%; expressing the second and third book values in terms of redemption C makes third-period premium amortization 39.0667 − 0.00625C, so C = 5,150, choice A.
These notes identify the calculation error associated with each wrong letter when that error is reproducible.
BChoice B is inconsistent with the third-period coupon-minus-book-interest amortization equation; no distinct standard single-step error producing it is identifiable.
CChoice C is inconsistent with the third-period coupon-minus-book-interest amortization equation; no distinct standard single-step error producing it is identifiable.
DChoice D is inconsistent with the third-period coupon-minus-book-interest amortization equation; no distinct standard single-step error producing it is identifiable.
EChoice E is inconsistent with the third-period coupon-minus-book-interest amortization equation; no distinct standard single-step error producing it is identifiable.

Original variant: third-period premium amortization from redemption
A 15-year bond has face 5,000, redemption 5,200, and 7% annual coupons paid quarterly. It yields 5.6% nominal convertible quarterly. Determine premium amortized in the third coupon payment.
A 4.56
B 5.56
C 6.56
D 7.56
E 8.56
Variant answer in brief
A prospective book-value schedule gives third-period premium amortization 6.56, choice C.
