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 nondepreciable assets. This means that the division has invested $91.0 million in assets with a salvage value of $54.6 million. Annual depreciation is $9.1 million. Annual operating cash flows are $20.1 million.
