4. Suppose that the discount rate is flat at 5% per annum with continuous compounding. A swap with a notional principal of $100 million in which 6% is received and six-month LIBOR is paid will last another 15 months. Payments are exchanged every six months. The six-month LIBOR rate at the last reset date (three months ago) was 7%. Day count is ignored. What is the value (in millions) of the swap? Show your calculation (Hint: the problem is similar to Example 7.1 in PPTs in the Blackboard)
