Problem:
You're trying to determine whether or not to expand your business by building a new manufacturing plant. The plant has an installment cost of $12 million, which will be depreciated straight-line to zero over its four-year life. If the plant has projected net income of $1,627,000, $1,512,000, $1,101,000, and $1,313,000 over these four years, what is the project's average accounting return (AAR)?
