B. The fifth year's net cash flow would be:

Sale of land, net of tax: The land is sold for $800,000 and cost $500,000. Since land is not depreciated, its tax basis is $500,000 (an asset's book value for tax purposes is called its tax basis). There will be a $300,000 gain on the sale that will be taxable at the rate of 40%, which is $120,000. Thus, the net cash flow from the sale of the land will be $800,000 - $120,000, or $680,000.Sale of building, net of tax: The building is sold for $500,000. Its tax basis at the end of the 5th year is $200,000 - (5 × $200,000) = $1,000,000. Since it is sold for $500,000, there is a loss of $500,000 on the sale. The tax benefit from the loss is $500,000 × .40, or $200,000. The net cash flow from the sale of the building is $500,000 + $200,000 tax benefit from the loss, or $700,000.Sale of equipment, net of tax: The equipment will be fully depreciated at the end of the 5th year. It will be sold for a net amount of $250,000 ($300,000 proceeds from sale minus removal cost of $50,000). The full net amount is taxable, so tax on the gain is $250,000 × .4, or $100,000. The net cash flow from the sale will therefore be $250,000 - $100,000, or $150,000. Total cash flow for Year 5 is $540,000 cash flow from operations after tax + $320,000 depreciation tax shield + $680,000 sale of land + $700,000 sale of building + $150,000 sale of equipment = $2,390,000.

1For tax purposes, the depreciable base is 100% of an asset's cost, regardless of which depreciation method is used and regardless of whether salvage value is expected.

2Depreciation on land is not included because land is not depreciated.
