Busch Corporation has an existing loan in the amount of $4.5 million with an annual interest rate of 5.5%. The company provides an internal company-prepared financial statement to the bank under the loan agreement. Two competing banks have offered to replace Busch Corporation's existing loan agreement with a new one. BMO has offered to loan Busch $4.5 million at a rate of 4.5% but requires Busch to provide financial statements that have been reviewed by a public accounting firm. Desjardins has offered to loan Busch $4.5 million at a rate of 3.5% but requires Busch to provide financial statements that have been audited. Busch Corporation's controller approached a public accounting firm and was given an estimated cost of $20,000 to perform a review and $45,000 to perform an audit
