The rate on a 5-year loan is highly variable; it could be as low as 7%, as high as 15%, but is expected to be 10% per year. The company will only move forward with the acquisition offer if the AW is below $6.1 million. The M&O cost is fixed at $3.1 million per year. The anticipated sales price of the company could be $2 million if the interest rate is 7% or as much as $2.5 million if the rate is 15%, but will most likely be about $2.3 million at the 10% per year rate. Is the decision to move forward with the acquisition sensitive to the loan interest rate and salvage value estimates?
