Capital investment decisions are long-term corporate finance decisions relating to fixed assets and capital structure. Decisions are based on several inter-related criteria. (1) Corporate management seeks to maximize the value of the firm by investing in projects which yield a positive net present value when valued using an appropriate discount rate in consideration of risk. (2) These projects must also be financed appropriately. (3) If no such opportunities exist, maximizing shareholder value dictates that management must return excess cash to shareholders (i.e., distribution via dividends). Capital investment decisions thus comprise an investment decision, a financing decision, and a dividend decision.
The investment decision
Management must allocate limited resources between competing opportunities (projects) in a process known as capital budgeting. Making this investment, or capital allocation, decision requires estimating the value of each opportunity or project, which is a function of the size, timing and predictability of future cash flows.
The financing decision
Achieving the goals of corporate finance requires that any corporate investment be financed appropriately. As above, since both hurdle rate and cash flows (and hence the riskiness of the firm) will be affected, the financing mix can impact the valuation and long-term management. Management must therefore identify the "optimal mix" of financing—the capital structure that results in maximum value. The sources of financing will, generically, comprise some combination of debt and equity financing. Financing a project through debt results in a liability or obligation that must be serviced, thus entailing cash flow implications independent of the project’s degree of success. Equity financing is less risky with respect to cash flow commitments, but results in a dilution of share ownership, control and earnings. The cost of equity is also typically higher than the cost of debt (see CAPM and WACC), and so equity financing may result in an increased hurdle rate which may offset any reduction in cash flow risk.
The dividend decision
Whether to issue dividends, and what amount, is calculated mainly on the basis of the company’s unappropriated profit and its earning prospects for the coming year. The amount is also often calculated based on expected free cash flows i.e. cash remaining after all business expenses, and capital investment needs have been met.
If there are no NPV positive opportunities, i.e. projects where returns exceed the hurdle rate, then – finance theory suggests – management must return excess cash to investors as dividends. This is the general case, however there are exceptions. For example, shareholders of a "Growth stock", expect that the company will, almost by definition, retain earnings so as to fund growth internally. In other cases, even though an opportunity is currently NPV negative, management may consider “investment flexibility” / potential payoffs and decide to retain cash flows; see above and Real options.
