9. Calculate the value of the following loans. Assume a face value of $100,000 and that the yield to maturity on each is 6%. All interest rates are stated as annual rates.
a. a 3-year interest only mortgage with a coupon rate of 6.75%, monthly payments of interest, and the entire principal repaid at maturity.
b. a 10-year, fully amortized mortgage with quarterly payments and an interest rate of 4.75%.
10. Calculate the duration of each loan from question 9.
9)
a)
The value of the loan is calculated using the following equation
Value of the loan = $ 102,054.44
-------------------------------------------------------------------------------------------------------------------
b)
The quarterly payment on the loan is calculated as follows
Quarterly payment = $3,155.12
The value of the loan is the present value of the quarterly payment discounted at the yield to maturity of 6% , compounded quarterly.
The present value is calculated as follows:-
Value of the loan = $ 94,388.08
----------------------------------------------------------------------------------------------------
10)
In the case of a, the duration of the loan is 36 months or 3 years.
In the case of b, the duration of the loan is 40 quarters or 10 years.
