Kindly explain me the following question with a well labelled diagram showing all the interest rate flows corectly and the appropriate calculations.

Two companies have investments which pay the following rates of interest:

	Fixed	Float
Firm a	6%	Libor
Firm b	8%	Libor+0.5%

Assume A prefers a fixed rate and B prefers a floating rate. If an intermediary charges both parties equally a 0.1% fee and any benefits are spread equally between Firm A and Firm B. If an intermediary charges both parties equally a 0.1% fee and any benefits are spread equally between Firm A and Firm B, what rates could A and B receive on their preferred interest rate? Show all working.
