Question

A bank offers your firm a revolving credit arrangement for up to $75 million at an interest rate of 1.57 percent per quarter. The bank also requires you to maintain a compensating balance of 4 percent against the unused portion of the credit line, to be deposited in a noninterest-bearing account. Assume you have a short-term investment account at the bank that pays .52 percent per quarter, and assume that the bank uses compound interest on its revolving credit loans.

What is your effective annual interest rate (an opportunity cost) on the revolving credit arrangement if your firm does not use it during the year? (Do not round intermediate calculations. Enter your answer as a percentage rounded to 2 decimal places (e.g., 32.16).)

What is your effective annual interest rate on the lending arrangement if you borrow $40 million immediately and repay it in one year? (Do not round intermediate calculations. Enter your answer as a percentage rounded to 2 decimal places (e.g., 32.16).)

The bank also requires you to maintain a compensating balance of 4 percent against the unused portion of the credit line, to be deposited in a noninterest-bearing account. Assume you have a short-term investment account at the bank that pays .52 percent per quarter, and assume that the bank uses compound interest on its revolving credit loans.

Explanation / Answer

Bank interest rate per quarte = .52%

so Annual effective rate = (1+.0052)^4 - 1 = .0209 or 2.09%

b)

To calculate the EAR of the loan, we can divide the interest on the loan by the amount of the loan. The interest onthe loan includes the opportunity cost of the compensating balance. The opportunity cost is the amount of thecompensating balance times the potential interest rate you could have earned. The compensating balance is only on the unused portion of the credit line,

so:Opportunity cost = 0.04($75,000,000 – 40,000,000)(1.0052)^4– 0.04($75,000,000 – 40,000,000) = $ 29,347.92

And the interest you will pay to the bank on the loan is:Interest cost = $40,000,000(1.0157)^4– 40,000,000 = $2,571,779.21

So, the EAR of the loan in the amount of $40,000,000 is = ($27,347.92 + 2,571,779.21)/$40,000,000= 0.0649 or 6.49%

c)

The compensating balance is only applied to the unused portion of the credit line, so the EAR of a loan on the full credit line is = 1.0157^4– 1 = 0.0643 or 6.43%
