In exchange for a $600 million fixed commitment line of credit, your firm has agreed to do the following:

1. Pay 2.0% per quarter on any funds actually borrowed.

2. Maintain a 5% compensating balance on any funds actually borrowed.

3. Pay an up-front commitment fee of 0.190% of the amount of the line.

Based on this information, answer the following:

a. Ignoring the commitment fee, what is the effective annual interest rate on this line of credit? (Do not round intermediate calculations. Round the final answer to 2 decimal places.)

Effective annual interest rate %

b. Suppose your firm immediately uses $100 million of the line and pays it off in one year. What is the effective annual interest rate on this $100 million loan? (Do not round intermediate calculations. Round the final answer to 2 decimal places.)
