CFA Practice Question

An inverse floater has coupon rate = Maximum [(18% - 2.5r) or 0], where r is the six-month LIBOR rate.
A. The cap coupon rate of 15.5% occurs when r = 1%.
B. The cap coupon rate of 18% occurs when r = 5.5%.
C. The floor coupon rate of 0% occurs when r = 7.2%.
Explanation: The coupon rate specification indicates that for all values of 6-month LIBOR greater than 7.2%, the coupon rate = Maximum [18% - 2.5*r or 0] = 0. The cap coupon rate is 18% when r = 0%.

Sudha i am confused. i agree with the answer but the formula holds good for "cap rate = 15.5%"? can somebody help? especially as the prefix is maximum.
nike the floor is 0 and the cap is 18% for this inverse-floater. Although B is correct in the formula the "cap coupon rate of 15.5%" is wrong.
nguyencamtam I am confused too, Sudha.
I think that maybe we have to find out the theoretical maximum and minimum points of the formula. If it is the case, then the answer is correct, because the minimum or the floor will be 0% when r = 7.2. It is correct only if "the cap will be 18% when r = 0".
Mak900 Usually the inverse floaters are structured to protect the holder by creating a floor value. In this question objective is to multiply 2.5 with a value of r so that 18%-2.5r=0,only 7.2% satisfies this condition. Therefore C is correct
kellyyang who can help me to explain how get the # 7.2%. I am still confused for the question!
kellyyang Never mind! I figured out how to get R=7.2: just used 18%/2.5=7.2
viruss Cap is 18% when r = 0 and Floor is 0% when r>=7.2%.
thekobe remember a cap is the maximum possible rate and floor is the minimum possible rate.
