The Street Division of Labrosse Logistics just started operations. It purchased depreciable assets costing $45.5 million and having a four-year expected life, after which the assets can be salvaged for $9.1 million. In addition, the division has $45.5 million in assets that are not depreciable. After four years, the division will have $45.5 million available from these non depreciable assets. This means that the division has invested $91 million in assets with a salvage value of $54.6 million. Annual operating cash flows are $13.9 million. In computing ROI, this division uses beginning-of-year asset values in the denominator. Depreciation is computed on a straight-line basis, recognizing the salvage values noted. Ignore taxes.
