ework (Chapter 14) Saved Help S The Ste Marie Division of Pacific Media Corporation just started operations. It purchased depreciable assets costing $35 million and having a four-year expected life after which the assets can be salvaged for $7 million. In addition, the division has $35 million in assets that are not depreciable After four years, the division will have $35 million available from these nondepreciable assets. This means that the division has invested $70 million in assets with a salvage value of $42 million Annual depreciation is $7 million Annual operating cash flows are $25 million. In computing ROI, this division uses end-of-year asset values in the denominator Depreciation is computed on a straight-line basis, recognizing the salvage values noted. Ignore taxes. Assume that all cash flows increase 10 percent at the end of each year. This has the following effect on the assets' replacement cost and annual cash flows Replacement cost Annual Cash flow $70,000,000 x 1.1 - $77,000,000 $ 25,000,000 X 1.1 $27,500,000 $77,000,000 X 1.1 - $84,700,000 $ 27,500,000 x 1.1 $30,250,000 Etc.
