Calculation of Sum of values of pure business flows and financing effect.
In the preceding problem, we divided the value of all the assets between two classes of investors: creditors and shareholders. This process tells us where the change in value is going, but it sheds little light on where the change is coming from. Let's divide the free cash flows of the firm into pure business flows and cash flows resulting from financing effects. Now, an axiom in finance is that you should discount cash flows at a rate consistent with the risk of those cash flows. Pure business flows should be discounted at the unlevered cost of equity (i.e., the cost of capital for the unlevered firm). Financing flows should be discounted at the rate of return required by the providers of debt.
