Every businesses
and firms try to maximize value and maintain it. Should they aim to achieve optimal capital structure?
What is the right mixture of debt and equity should a firm take? Does optimal
capital structure exist in the real world? Is it possible for a firm to achieve
optimal capital structure? I don’t think so because it is hard to predict the
market value of an equity share exactly. Different causes from the market that
affect market value of equity share are extremely complicated. A rise in debt
will decrease the equity in capital structure, causing imbalance between debt
and equity. I think that aiming to achieve optimal capital structure is somehow
not necessary if the company is well financed.
Furthermore, I personally think that it is hard for a firm to measure
that whether they should finance the company by debt,by equity or by both as both have its own
advantages and disadvantages. To me, I think that debt financing is a better
option due to its cheaper cost. Let’s take Wal-Mart as an example. Wal-Mart has capital
structure which contain a mixture of
debt and equity. According to Ycharts, the
debt-to-equity ratio of Walmart was at 0.5621 back to July of this year, which is
lower than the industry average. This demonstrates that Wal-Mart has been
successful in managing their debt than equity level. From there,I can conclude
that Wal-Mart has lower risk and higher solvency. This may be due to the reduced tax paid, the fall in
claiming on company’s asset from debt holders, and cheaper transaction cost for debt compared to ordinary shares.

However, Modigliani And Miller's theory (1958) argue that financing by debt or equity does not matter, it will not affect the WACC. Thus, no optimal structure exists. They assume that there is no taxation, no bankruptcy cost, perfect information is available to all economic agent with no cost of transaction and individuals can as much as they want as they can borrow as the same rate as companies. They believed that the company’s value depends purely on business risk. Are these true? Can these be accepted in the real world? I disagree with the assumption that M&M have made. Bankruptcy costs and taxes do make changes to the stock price of a company and the stock price will finally affect the performance of a company. Income taxes exist and its beneficial to debt whereas bankruptcy cost is is large in amount in the real world.
Besides that, information available to economic agent is not always perfect. Individuals too cannot borrow as cheap as companies as interest rate usually go up as they ask for more money. Therefore, i don't think it is acceptable in the real world. However, after realizing the importance and impact of tax on business, M&M decided to revised their paper and take tax into account in 1963. in this assumption, debt is more favorable because it is a tax deductible expense which can be offset against profit. in other way, it assume that an increase in gearing will reduce weighted average cost capital (WACC).
Is it a good idea if a company keep increasing the gearing to reduce WACC? NO! Definitely not. Although debt has its own benefit at some point, but company should not keep accumulating their debt just to reduce their WACC. These debt will drag down the reputation of their own company. The debts have to be repaid anyway, so a company should stop accumulating their debt at certain level.
