An engineer is planning for a financial review where a machining center will be evaluated for replacement against a challenger. The asset was purchased for $130,000 several years ago. As a result of its specialized design, its salvage value is now at 16% of the FC, dropping by 1% per year through its remaining 5-year life. The AOC estimates start at $15,000 in Y1, increasing in Y2 and Y3 by $17,000 over the previous year. AOC then increases by $27,000 in Y4 and again in Y5.

Using the company's MARR of 10% calculate the economic service life over the 5 remaining years and the Total AW per year at the ESL.
