We do not follow the common practice of talking one-on-one with large institutional investors or analysts, treating them instead as we do all other shareholders. There is no one more important to us than the shareholder of limited means who trusts us with a substantial portion of his or her savings. As I run the company day-to-day — and as I write this letter — that is the shareholder whose image is in my mind.

The primary test of managerial economic performance is the achievement of a high earnings rate on equity capital employed (without undue leverage, accounting gimmickry, etc.) and not the achievement of consistent gains in earnings per share. In our view, many businesses would be better understood by their shareholder owners, as well as the general public, if managements and financial analysts modified the primary emphasis they place upon earnings per share, and upon yearly changes in that figure.

The line separating investment and speculation, which is never bright and clear, becomes blurred still further when most market participants have recently enjoyed triumphs. Nothing sedates rationality like large doses of effortless money. After a heady experience of that kind, normally sensible people drift into behavior akin to that of Cinderella at the ball. They know that overstaying the festivities — that is, continuing to speculate in companies that have gigantic valuations relative to the cash they are likely to generate in the future — will eventually bring on pumpkins and mice. But they nevertheless hate to miss a single minute of what is one helluva party. Therefore, the giddy participants all plan to leave just seconds before midnight. There’s a problem, though: They are dancing in a room in which the clocks have no hands.

In addition to being independent, directors should have business savvy, a shareholder orientation and a genuine interest in the company. The rarest of these qualities is business savvy — and if it is lacking, the other two are of little help. Many people who are smart, articulate and admired have no real understanding of business. That’s no sin; they may shine elsewhere. But they don’t belong on corporate boards.
