A company is planning to issue a 5 year $100 million bond at a fixed rate of 6%.

It is also considering whether or not to enter into a 10 year $100 million swap to receive 5% fixed and pay Libor + 1% once a year.

The company predicts that Libor will be 4% over the life of the 5 years.

What is the impact of the swap on the company's annual interest cost assuming that the Libor prediction is correct?
