Exercise 14-39 (Algo) Compare Historical Cost, Net Book Value to Gross Book Value (LO 14-2, 5) The Ste. Marie Division of Pacific Media Corporation just started operations. It purchased depreciable assets costing $41.5 million and having a four-year expected life, after which the assets can be salvaged for $8.3 million. In addition, the division has $41.5 million in assets that are not depreciable. After four years, the division will have $41.5 million available from these nondepreciable assets. This means that the division has invested $83.0 million in assets with a salvage value of $49.8 million. Annual depreciation is $8.3 million. Annual operating cash flows are $21.4 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.
