Davis Industries must choose between a gas-powered and an electric-powered forklift truck for moving materials in its factory. Since both forklifts perform the same function, the firm will choose only one. (They are mutually exclusive investments.) The electric-powered truck will cost more, but it will be less expensive to operate; it will cost $21,500, whereas the gas-powered truck will cost $17,960. The cost of capital that applies to both investments is 13%. The life for both types of truck is estimated to be 6 years, during which time the net cash flows for the electric-powered truck will be $6,860 per year and those for the gas-powered truck will be $4,600 per year. Annual net cash flows include depreciation expenses.

After discovering a new gold vein in the Colorado mountains, CTC Mining Corporation must decide whether to mine the deposit. The most cost-effective method of mining gold is sulfuric acid extraction, a process that results in environmental damage. Before proceeding with the extraction, CTC must spend $900,000 for new mining equipment and pay $165,000 for its installation. The gold mined will net the firm an estimated $350,000 each year over the 5-year life of the vein. CTC's cost of capital is 17%. For the purposes of this problem, assume that the cash inflows occur at the end of the year.

c. How should environmental effects be considered when evaluating this, or any other, project?
_________________
I. Environmental effects should be ignored since they would have no effect on the project's profitability.
II. Environmental effects should be treated as sunk costs.
III. Environmental effects could be added by estimating penalties or any other cash outflows that might be imposed on the firm to help return the land to its previous state (if possible).
