• Why are many common rules of thumb for evaluating a company’s debt capacity misleading and even dangerous?
  • Why is outside experience and advice of limited value as a guide to top management’s thinking about debt capacity?
  • What approach will enable management to make an independent and realistic appraisal of risk on the basis of data with which it is already familiar and in terms of judgments to which it has long been accustomed?

The problem of deciding whether it is wise and proper for a business corporation to finance long-term capital needs through debt, and, if so, how far it is safe to go, is one which most boards of directors have wrestled with at one time or another. For many companies the debt-capacity decision is of critical importance because of its potential impact on margins of profitability and on solvency. For all companies, however large and financially sound they may be, the decision is one to be approached with great care. Yet, in spite of its importance, the subject of corporate debt policy has received surprisingly little attention in the literature of business management in recent years. One might infer from this either that business has already developed a reliable means of resolving the question or that progress toward a more adequate solution has been slow.
