Think about whether a company's unrestricted earnings should be retained or paid out. The analysis is much more difficult and subject to error because the rate earned on reinvested earnings is not a contractual figure, as in our bond case, but rather a fluctuating figure. Owners must guess as to what the rate will average over the intermediate future. However, once an informed guess is made, the rest of the analysis is simple: you should wish your earnings to be reinvested if they can be expected to earn high returns, and you should wish them paid to you if low returns are the likely outcome of reinvestment. Many corporate managers reason very much along these lines in determining whether subsidiaries should distribute earnings to their parent company. At that level,. the managers have no trouble thinking like intelligent owners. But payout decisions at the parent company level often are a different story. Here managers frequently have trouble putting themselves in the shoes of their shareholder-owners.

With this schizoid approach, the CEO of a multi-divisional company will instruct Subsidiary A, whose earnings on incremental capital may be expected to average 5%, to distribute all available earnings in order that they may be invested in Subsidiary B, whose earnings on incremental capital are expected to be 15%. The CEO's business school oath will allow no lesser behavior. But if his own long-term record with incremental capital is 5% - and market rates are 10% - he is likely to impose a dividend policy on shareholders of the parent company that merely follows some historical or industry-wide payout pattern. Furthermore, he will expect managers of subsidiaries to give him a full account as to why it makes sense for earnings to be retained in their operations rather than distributed to the parent-owner. But seldom will he supply his owners with a similar analysis pertaining to the whole company.

In judging whether managers should retain earnings, shareholders should not simply compare total incremental earnings in recent years to total incremental capital because that relationship may be distorted by what is going on in a core business. During an inflationary period, companies with a core business characterized by extraordinary economics can use small amounts of incremental capital in that business at very high rates of return. But, unless they are experiencing tremendous unit growth, outstanding businesses by definition generate large amounts of excess cash. If a company sinks most of this money in other businesses that earn low returns, the company's overall return on retained capital may nevertheless appear excellent because of the extraordinary returns being earned by the portion of earnings incrementally invested in the core business. The situation is analogous to a Pro-Am golf event: even if all of the amateurs are hopeless duffers, the team's best-ball score will be respectable because of the dominating skills of the professional.

Many corporations that consistently show good returns both on equity and on overall incremental capital have, indeed, employed a large portion of their retained earnings on an economically unattractive, even disastrous, basis. Their marvelous core businesses, however, whose earnings grow year after year, camouflage repeated failures in capital allocation elsewhere (usually involving high-priced acquisitions of businesses that have inherently mediocre economics). The managers at fault periodically report on the lessons they have learned from the latest disappointment. They then usually seek out future lessons. (Failure seems to go to their heads.)

In such cases, shareholders would be far better off if earnings were retained only to expand the high-return business, with the balance paid in dividends or used to repurchase stock (an action that increases the owners' interest in the exceptional business while sparing them participation in subpar businesses). Managers of high-return businesses who consistently employ much of the cash thrown off by those businesses in other ventures with low returns should be held to account for those allocation decisions, regardless of how profitable the overall enterprise is.

Nothing in this discussion is intended to argue for dividends that bounce around from quarter to quarter with each wiggle in earnings or in investment opportunities. Shareholders of public corporations understandably prefer that dividends be consistent and predictable. Payments, therefore, should reflect
