equal to the rise in the CPI". And that's it - no analysis will be supplied as to why that particular policy is best for the owners of the business. Yet, allocation of capital is crucial to business and investment management. Because it is, we believe managers and owners should think hard about the circumstances under which earnings should be retained and under which they should be distributed.

The first point to understand is that all earnings are not created equal. In many businesses particularly those that have high asset/profit ratios - inflation causes some or all of the reported earnings to become ersatz. The ersatz portion - let's call these earnings "restricted" - cannot, if the business is to retain its economic position, be distributed as dividends. Were these earnings to be paid out, the business would lose ground in one or more of the following areas: its ability to maintain its unit volume of sales, its long-term competitive position, its financial strength. No matter how conservative its payout ratio, a company that consistently distributes restricted earnings is destined for oblivion unless equity capital is otherwise infused.

Restricted earnings are seldom valueless to owners, but they often must be discounted heavily. In effect, they are conscripted by the business, no matter how poor its economic potential. (This retention-no-matter-how-unattractive-the-return situation was communicated unwittingly in a marvelously ironic way by Consolidated Edison a decade ago. At the time, a punitive regulatory policy was a major factor causing the company's stock to sell as low as one-fourth of book value; i.e., every time a dollar of earnings was retained for reinvestment in the business, that dollar was transformed into only 25 cents of market value. But, despite this gold-into-lead process, most earnings were reinvested in the business rather than paid to owners. Restricted earnings need not concern us further in this dividend discussion.

Let's turn to the much-more-valued unrestricted variety. These earnings may, with equal feasibility, be retained or distributed. In our opinion, management should choose whichever course makes greater sense for the owners of the business. This principle is not universally accepted. For a number of reasons managers like to withhold unrestricted, readily distributable earnings from shareholders - to expand the corporate empire over which the managers rule, to operate from a position of exceptional financial comfort, etc. But we believe there is only one valid reason for retention. Unrestricted earnings should be retained only when there is a reasonable prospect - backed preferably by historical evidence or, when appropriate, by a thoughtful analysis of the future - that for every dollar retained by the corporation, at least one dollar of market value will be created for owners. This will happen only if the capital retained produces incremental earnings equal to, or above, those generally available to investors.

To illustrate, let's assume that an investor owns a risk-free 10% perpetual bond with one very unusual feature. Each year the investor can elect either to take his 10% coupon in cash, or to reinvest the coupon in more 10% bonds with identical terms; i.e., a perpetual life and coupons offering the same cash-or-reinvest option. If, in any given year, the prevailing interest rate on long-term, risk-free bonds is 5%, it would be foolish for the investor to take his coupon in cash since the 10% bonds he could instead choose would be worth considerably more than 100 cents on the dollar. Under these circumstances, the investor wanting to get his hands on cash should take his coupon in additional bonds and then immediately sell them. By doing that, he would realize more cash than if he had taken his coupon directly in cash. Assuming all bonds were held by rational investors, no one would opt for cash in an era of 5% interest rates, not even those bondholders needing cash for living purposes.

If, however, interest rates were 15%, no rational investor would want his money invested for him at 10%. Instead, the investor would choose to take his coupon in cash, even if his personal cash needs were nil. The opposite course - reinvestment of the coupon - would give an investor additional bonds with market value far less than the cash he could have elected. If he should want 10% bonds, he can simply take the cash received and buy them in the market, where they will be available at a large discount.
