Final answer:
a. The cash flow is $330,000. b. With $550,000 depreciation, the cash flow is $0. c. The cash flow benefit from depreciation is $220,000.
Step-by-step explanation:
a. To compute the cash flow, we need to find the earnings after taxes. Assuming a 40 percent tax bracket, the firm's earnings after taxes would be $550,000 - ($550,000 * 0.40) = $330,000. Therefore, the cash flow would be $330,000.
b. If the firm has $550,000 in depreciation, the taxable income would be reduced to $550,000 - $550,000 = $0. Therefore, the earnings after taxes would also be $0. Hence, the cash flow would be $0.
c. The depreciation provided a cash flow benefit equal to the tax amount saved. In this case, the firm saved $550,000 * 0.40 = $220,000 in taxes due to depreciation.
