Question 5: (a) Discuss M & M Proposition I of capital structure.

Modigliani and Miller (M&M) Proposition I, also known as the capital structure irrelevance principle, is a significant theory in corporate finance developed by economists Franco Modigliani and Merton Miller in 1958. This proposition is based on a set of assumptions and conclusions that provide insights into the relationship between a firm’s capital structure and its market value. The main ideas of M&M Proposition I are as follows:

Assumptions:

1. Perfect Capital Markets: M&M Proposition I assumes that capital markets are efficient and frictionless, meaning there are no taxes, transaction costs, or other barriers to the free flow of capital.
2. No Bankruptcy Costs: The proposition assumes that bankruptcy costs do not exist, implying that firms can borrow and lend at the same rate as individuals.
3. Homogeneous Expectations: All investors and stakeholders have the same expectations and access to information, leading to the same risk perceptions and discount rates.

Conclusion – Capital Structure Irrelevance: M&M Proposition I states that the value of a firm is independent of its capital structure. In other words, the market value of a company is not influenced by its debt-to-equity ratio or the way it finances its investments. Under perfect capital markets and the assumptions mentioned above, the weighted average cost of capital (WACC) remains constant for all levels of leverage.

Explanation: The core idea behind M&M Proposition I is that investors can replicate any capital structure by combining risk-free debt with the company’s equity. According to the proposition, if a firm increases its debt levels and the financial risk, shareholders require a higher return on equity to compensate for the additional risk. As a result, the cost of equity increases in proportion to the increased financial risk, offsetting any benefit from the tax deductibility of interest payments.

Similarly, if a firm reduces its debt levels and financial risk, shareholders would demand a lower return on equity, but this would be compensated by the lower tax shield provided by debt. As a result, the cost of equity would decrease, again leading to no effect on the overall market value of the firm.

Significance: M&M Proposition I laid the groundwork for understanding the relationship between capital structure and firm value. It highlights that in perfect capital markets without taxes and bankruptcy costs, the way a firm chooses to finance its investments does not impact the overall value of the firm. In such an ideal scenario, firms can maximize their value by investing in projects with positive net present value (NPV), irrespective of the mix of debt and equity used to finance those projects.

However, it is important to note that M&M Proposition I’s assumptions are highly idealized and rarely hold true in the real world. In the real market, taxes, bankruptcy costs, information asymmetry, and agency costs influence capital structure decisions and can impact a firm’s value.

In practice, managers need to consider various factors, such as taxes, financial distress costs, and the signaling effect of debt, when determining an optimal capital structure. While M&M Proposition I provides valuable theoretical insights, real-world financial decisions often involve trade-offs and complexities that require careful analysis and consideration of multiple factors.
