As the CFO of your company, it falls to you to make the final decision on large expenditures. Recently, your controller has proposed purchasing a new computer system at a cost of $53,000. He believes the system will deliver savings of $66,000 in the accounting department and could be useful to other departments as well. Your treasurer takes a decidedly different view of the proposal.
