The Ste. Marie Division of Pacific Media Corporation just started operations. It purchased depreciable assets costing $39 million and having a four-year expected life, after which the assets can be salvaged for $7.8 million. In addition, the division has $39 million in assets that are not depreciable. After four years, the division will have $39 million available from these nondepreciable assets. This means that the division has invested $78 million in assets with a salvage value of $46.8 million. Annual depreciation is $7.8 million. Annual operating cash flows are $26 million. Depreciation is computed on a straight-line basis, recognizing the salvage values noted. Ignore taxes.
