Determine the FCFF for a company with net income of $180,000, depreciation expense of $20,000, increase in working capital of $10,000, and capital expenditures of $50,000. Discuss the significance of FCFF in corporate valuation and financial analysis. Analyze how changes in net income, working capital, and capital expenditures can affect FCFF. Consider the strategic implications of FCFF for investment decisions, debt management, and shareholder returns. Discuss how FCFF is used in discounted cash flow (DCF) valuation models to estimate the intrinsic value of a company. Explain how FCFF differs from other cash flow metrics, such as free cash flow to equity (FCFE) and net cash provided by operating activities, and why it is particularly relevant for debt and equity investors.
