What are the three reasons why a firm's capital structure affects total after-tax cash flows as mentioned in the chapter?

A firm's capital structure affects total after-tax cash flows for three reasons: 1) Interest on debt is tax-deductible, whereas dividends are not, allowing firms to retain more cash when using debt. 2) Debt creates a fixed legal obligation, and defaulting can lead to bankruptcy costs. 3) The threat of bankruptcy can influence managerial behavior and impact the firm's attractiveness to employees and suppliers.

The capital structure of a firm significantly influences its total after-tax cash flows due to three primary factors. First, under the U.S. tax code, interest payments on debt are tax-deductible, which means firms can distribute more cash to stakeholders when they utilize debt financing compared to equity financing. Second, debt financing imposes a fixed obligation on the firm; if it fails to meet these obligations, it risks bankruptcy, which incurs additional costs. Lastly, the potential threat of bankruptcy can affect how executives manage the firm, potentially focusing their efforts on improving performance, but it can also make the firm less appealing to employees and suppliers.
