In a recent paper in Administrative Science Quarterly, Aharon Mohliver looks at an even more interesting part of this relationship by doing research on the role that auditors played in first condoning, then spreading, and finally extinguishing a questionable practice firms began to use when changes in the tax code affected their ability to pay managers above a $1 million cap without subjecting them to significant tax liabilities. At first the practice was questionable but not illegal, and auditors in some local offices helped their client firms start using it. The findings tell a very informative story of how auditors pay close attention to the interests of the managers who hire them, and also to the fine line between legal and illegal.
The questionable practice is called stock-option backdating. Stock options are often given to managers because they let managers earn higher income if the value of the firm increases, and to make them fair they are often given (for free, of course) at the exact value of the firm on the day they are given. In MBA-speak, those options have upside potential, no downside potential, and are incentive compatible. In plainer words, they reward managers for effective management but don’t punish failure. Firms report the costs of stock options as compensation expenses.
What I just explained is a regular stock option, without backdating. A backdated stock option looks just the same, but in reality it has been assigned an earlier formal date than when it was given, and that formal date somehow turns out to be a day just before the firm had a big increase in value. Through what seems like a very lucky dating of the option, the managers getting the backdated stock option earn significant sums of money not taxed as regular income. Backdated stocks are a trick for compensating managers at the expense of investors. They are a form of fraud, and though they were unethical from the start, initially there were no laws or rules against backdating so they were not yet illegal. (There were no rules because no one making rules had thought of backdating stock options.)
So the auditors stepped in. They spread knowledge of backdating from one client to the next, especially if clients were part of their local and dense communication networks. They were also sensitive to lawmakers, however, so this spreading of backdating was strongest when the uncertainty about the legality of backdating was greatest. When it became more certain that backdating would be made illegal, the auditors stopped spreading the backdating trick, and when it actually became illegal they stopped its use in the firms that had already started using backdating. So, auditors follow written law very well, are neutral to law that will soon happen, and are willing to help management profit from legally questionable conduct. Nice to know if you happen to be a manager, investor, or lawmaker. If you are an auditor you probably know it already.
