The idea of an optimal capital structure has been around for many years and relates to the financial makeup of a company and the split between debt and equity finance. The optimal capital structure of any company, relates to the point where debt financing is equal to less than the cost of equity. It is the best debt to equity ratio for the company to maximise its value. Basically, finance the company through debt until the cost of debt becomes higher than or equal to the cost of equity, as generally the cost of equity is higher due to the expected returns. Although, debt financing is risky and in turn adding more debt into the company, will increase the shareholders required rates of returns, due to the extra risk factors.
Personally, I believe a structure that is less focused on debt and has a lower gearing level is better, regardless of whether it is classed as being the ‘optimal capital structure’. The lower the debt, the lower the risk in a way, as even in a recession debts still have to be paid, whereas dividends do not have to be issued. Through the latest recession, many companies have gone into administration through reliance on debt and high levels of gearing. Examples include Peacocks, Blacks Leisure, La Senza and major banks have been guilty of having reliance on debt finance. The theoretical ideal believes that through not reaching the optimal point, companies are basically ‘robbing’ shareholders of potential wealth. While this may be true, the idea of shareholder wealth is to create wealth over a long period which is sustainable. If companies reach the optimal point and are highly geared, in times of economic hardship this could affect the shareholder negatively, compared to a competitor which has a higher percentage of equity.
Some companies also take this view and actively work to reduce the amount of debt and gearing levels they have within the company. For example in 2009, De Beers raised a rights issue, in order to improve their capital structure and reduce the amount of debt through increased equity. This happened at a time when diamond prices were at a low and through decreasing the amount of debt, reduced the demands upon them during a recession. This was through reducing the required monthly repayments of the loans, as shareholders do not have to legally receive a dividend each year, unlike loans which have to be repaid on time.
Increasing debt level can help to reduce the tax bill of the organisation as debt interest payments are tax deductable, unlike dividend payments which are paid after tax, again increasing the cost of equity compared to debt. I can fully understand why companies use debt as a financing tool, due to the low cost available to them, but there is a risk of becoming dependent upon debt like Thomas Cook did and when recession strikes, high debt levels can case large problems which raises the question is debt really the cheapest option when an economic downturn occurs?
When Modigliani and Millar (1958) wrote their first major paper on optimal structure, they made the assumption that tax was not a relevant factor. This lead to them having to revise their paper in 1963 to take into account the affect tax can have upon businesses, although they seemed to say the best option was to load up on debt, moving companies away from the traditional model of capital structure and the optimal capital structure.
Personally, I agree with the traditional model, where loading up on debt and having a high gearing level impacts the required returns due to the high risks involved. We have all seen the prices that are paid for having unsustainable debt levels, although, every company is different and recession proof industries may be able to cope with high debt levels. The optimal capital structure of a company has to stem from the strategy of the business and the views of existing shareholders. If shareholders are debt adverse, then they will dramatically increase the required rate of returns, meaning debt finance may not be the best option.
I can see why companies try and chase the optimal capital structure of their business, due to the benefits of reduced Weighted Average Cost of Capital, but is it in the company’s best interest to spend a considerable amount of time on this when the resources can often be put to better uses? Industries have a ‘norm’ and companies aim to be within their industry norm to prevent investors feeling they are risky. We have all seen the impacts of being too debt dependent, through the latest recession and many companies going out of business, so surely it is in the company and shareholders best interests to pursue a capital strategy which works best for them and enables them to run the business efficiently?
