Garco is considering replacing an old machine that is currently being used. The old machine is fully depreciated, but it can be used for another five years, at which time it would have no terminal value. Garco can sell the old machine for $60 000 on the date that the new machine is purchased. If the purchase occurs, the new machine will be acquired for a cash payment of $1 million.
