The Ste. Marie Division of Pacific Media Corporation just started operations. It purchased depreciable assets costing $49.0 million and having a four-year expected life, after which the assets can be salvaged for $9.8 million. In addition, the division has $49.0 million in assets that are not depreciable. After four years, the division will have $49.0 million available from these nondepreciable assets. This means that the division has invested $98.0 million in assets with a salvage value of $58.8 million. Annual depreciation is $9.8 million. Annual operating cash flows are $20.8 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
