Assume you work for a firm that needed to borrow $25,000,000 in June of 2019 and would be paying an interest rate based in LIBOR. If you wanted to hedge your exposure to a change in LIBOR rates how many contracts would you sell? I found the LIBOR in earlier question it's 2.98%

Based on your answer, how much margin would you be required to deposit (assuming you are classified as a hedger and only need to deposit the maintenance margin)?

If in June of 2019 at the settlement of the contract LIBOR rates end up being 3.25%, what would be the total gain or loss on your position in the contract (assuming you held them until expiration)?
