"In recent years, probity has eroded. Many major corporations still play things straight, but a significant and growing number of otherwise high-grade managers — CEOs you would be happy to have as spouses for your children or as trustees under your will — have come to the view that it’s okay to manipulate earnings to satisfy what they believe are Wall Street’s desires. Indeed, many CEOs think this kind of manipulation is not only okay, but actually their duty. These managers start with the assumption, all too common, that their job at all times is to encourage the highest stock price possible (a premise with which we adamantly disagree). To pump the price, they strive, admirably, for operational excellence. But when operations don’t produce the result hoped for, these CEOs resort to unadmirable accounting stratagems. These either manufacture the desired “earnings” or set the stage for them in the future. Rationalizing this behavior, these managers often say that their shareholders will be hurt if their currency for doing deals — that is, their stock — is not fully-priced, and they also argue that in using accounting shenanigans to get the figures they want, they are only doing what everybody else does. Once such an everybody’s-doing-it attitude takes hold, ethical misgivings vanish. Call this behavior Son of Gresham: Bad accounting drives out good."
