Answer:
True
Step-by-step explanation:
Unlevered free cash flows represent the amount of cash a business has before meeting it's financial obligations such as operating expenses or periodic interest payments on borrowed funds.
When a firm issues further debt, it's available funds increase. Similarly, if a firm retires or repays it's debt, it's available funds decrease.
Therefore, change in capital structure by issue or retirement of debt alters a firm's unlevered free cash flows.
