There's a "rachet effect" - BigCorp needs a new CEO, the committee looks for a replacement. Are they looking for an "average" CEO or an above average CEO? Compensation gets decided by a separate committee who use consultants who want to get re-hired. Buffett wrote about this in his 2005 letter to shareholders:
"Too often, executive compensation in the U.S. is ridiculously out of line with performance. That won’t change, moreover, because the deck is stacked against investors when it comes to the CEO’s pay. The upshot is that a mediocre-or-worse CEO – aided by his handpicked VP of human relations and a consultant from the ever-accommodating firm of Ratchet, Ratchet and Bingo – all too often receives gobs of money from an ill-designed compensation arrangement.
Take, for instance, ten year, fixed-price options (and who wouldn’t?). If Fred Futile, CEO of Stagnant, Inc., receives a bundle of these – let’s say enough to give him an option on 1% of the company – his self-interest is clear: He should skip dividends entirely and instead use all of the company’s earnings to repurchase stock.
Let’s assume that under Fred’s leadership Stagnant lives up to its name. In each of the ten years after the option grant, it earns $1 billion on $10 billion of net worth, which initially comes to $10 per share on the 100 million shares then outstanding. Fred eschews dividends and regularly uses all earnings to repurchase shares. If the stock constantly sells at ten times earnings per share, it will have appreciated 158% by the end of the option period. That’s because repurchases would reduce the number of shares to 38.7 million by that time, and earnings per share would thereby increase to $25.80. Simply by withholding earnings from owners, Fred gets very rich, making a cool $158 million, despite the business itself improving not at all. Astonishingly, Fred could have made more than $100 million if Stagnant’s earnings had declined by 20% during the ten-year period.
Fred can also get a splendid result for himself by paying no dividends and deploying the earnings he withholds from shareholders into a variety of disappointing projects and acquisitions. Even if these initiatives deliver a paltry 5% return, Fred will still make a bundle. Specifically – with Stagnant’s p/e ratio remaining unchanged at ten – Fred’s option will deliver him $63 million. Meanwhile, his shareholders will wonder what happened to the “alignment of interests"
Really nice buffet selection, a perhaps more notably because he mostly seems to defend stock repurchases (presumably baring some outlandish ceo grant like in the quote) due to the tax deferred accumulation.
