Understanding the Purpose of Interest Rate Swaps

Consider a scenario where two companies, Company A and Company B, enter into a 5-year interest rate swap. Company A will pay a fixed interest rate of 3% while receiving a floating rate based on LIBOR, and Company B will pay a floating rate based on LIBOR while receiving a fixed rate of 3%. Assuming that the notional principal of the swap is $10 million, what is the main purpose of entering into this interest rate swap for Company A?

Understand that swaps are often used to manage interest rate risk, and they can be beneficial in matching cash flows to liabilities.
