Hello, I just want to check if my range of 1.1 X

P.S. Remember our final effective rate needs to be larger than our own fixed/floating rate (negative number since it is a cash outflow) to create an incentive for participating in a swap. D has a comparative advantage in borrowing floating and E has a comparative advantage in borrowing fixed

Because of the nature of their business, Firm D needs to secure effectively fixed-rate financing, while Firm E needs to secure effectively floating-rate financing. A financial institution is willing to be the intermediary in an interest rate swap between Firm D and E if it can obtain at least 0.2% from the swaps as fees. What is the range of value of X in the following swap arrangement to ensure there are incentives for all the parties (Firm D, Firm E, and the financial institution) to get involved? Note that the financial institution will not be interested if it cannot secure a cash flow of at least 0.2%
