Risk Differences in Shareholders’ and Creditors’ Claims

Risk Differences in Shareholders’ and Creditors’ Claims

Investors will require different rates of return on various securities since they have risk differences. Higher the risk of a security, the higher the rate of return demanded by investors. Since ordinary share is most risky, investors will require highest rate of return on their investment in ordinary shares. Preference share is more risky than debt; therefore, its required rate of return will be higher than that debt. The risk return relationship for various securities is shown in above figure, It may be observed in the figure that the required rate of any security is composed of two rates a risk free rate and risk premium. A risk free will require compensation for time value and its risk premium will be zero. Government securities, such as the treasury bills and bonds, are examples of the risk free securities. Investors expect higher rates of return on risky securities. The higher then risk of a security, the higher will be its risk premium, and therefore, a higher required rate of return.

Since the firm sells various securities to investors to raise capital for financing investment projects, it is necessary that investment projects to be undertaken by the firm should generate at least sufficient net cash flow to pay investors’ shareholders and debt holders their required rates of return. In fact, investment projects should yield more cash flows than to just satisfy the investors’ expectations in order to make a net contribution to the wealth of ordinary shareholders.

Viewed from all investors point of view, the firms cost of capital is the rate of return required by them for supplying capital for financing the firms investment projects by purchasing various securities. It may be emphasized that the rate of return required by all investors will be an overall rate of return a weighted rate of return. Thus, the firms cost of capital is the “average” of the opportunity costs of various securities, which have claims on the firms assets. This rate reflects both the business risk and financial risk resulting from debt capital. Recall that the cost of capital of an all equity financed firm is simply equal to the ordinary shareholders’ required rate of return, which reflects only the business risk.

Formula for the Opportunity Cost of Capital

The required rates of return are market-determined. They are established in the capital markets by the actions of competing investors. The influence of market is direct in the case of new issue of ordinary and preference shares and debt.

The market price of securities is a function of the return expected by investors. The demand and supply force in such a way that equilibrium rates are established for various securities. Thus opportunity cost of capital is given by the following formula,Where interest in year zero is the capital supplied by investors in period 0 (it represents a net cash inflows to the firm) Ct are returns expected by investors (they represent cash outflows to the firm) and k is the required rate of return or the cost of capital.
