coupon payment.
a. A 4% coupon, 10-year Treasury bond
. A 6% coupon, 10-year Treasury bond

cu
ent LIBOR is 1%.

a. Coupon rate = K + L*(reference rate), where K and L are values specified in the
prospectus for the issue
. Coupon rate = K - L*(reference rate), where K and L are values specified in the
prospectus for the issue
c. Coupon rate –K = L*(reference rate), where K and L are values specified in the
prospectus for the issue

7. Consider a five-year maturity floating rate bond with coupon rate as LIBOR+3%.
Suppose annual coupon payment frequency and par value is $1,000. The cu
ent one-year
interest rate is 1%. At the end of the first, second, third, fourth, and fifth year, the one-
year interest rate is 2%, 2.5%, 2%, 2.75%, and 2.25%, respectively. What are the cash
flows of this bond?

3*LIBOR+6%. Its discount rate is LIBOR+2%. The Par value of this floater is $1,000.
Two-year fixed coupon bonds’ prices are $980, $990, $995, $1005, and $1020 when
coupon rate is 0%, 1%, 2%, 3%, and 4%, respectively. What is the price of this floater?
9. Assume a four-year maturity float-rate bond. Par value is $1,000. Its discount rate is
LIBOR+3%. The discount rate for fixed cash flows is 5%. Its coupon rate is LIBOR+1%.
a. What is the price of this floater?
. What is the modified duration of this floater?
c. What is the convexity of this floater?
