the yield rate as a nominal rate convertible semi-annually. [8] (b) (i) In a bond amortization schedule, what does the "book value" mean? Describe in words. [2] (ii) Consider a n-period coupon bond where the redemption amount, C may not be the same as the face amount, F. Using j and g to represent the yield rate per period and modified coupon rate per period respectively, show that, for k=0,1,2,⋯,n, the book value at time k,B k
​
is B k
​
=C+C(g−j)a n−kj
​
, and the amortized amount at time k is PR k
​
=C(g−j)v j
n−k+1
