Executives Play Stock Options Backdating Game

The Sarbanes-Oxley Act has done little to deter corporate executives from manipulating stock options, according to a study by two University of Michigan professors earlier this year. Egregious discrepancies in reporting option grants have gone largely unnoticed since the act was passed in Congress in 2002, the report found.

Its authors, M. P. Narayanan and H. Nejat Seyhun, who are business professors of finance, argue that strategic market timing and late reporting are the chief methods of stock-option abuse. It’s a clever game, they posit, with two major ways to win.

“Executives can move the date of the option grant around, so that it ‘happens’ either before a good announcement or after a bad one,” said Seyhun. “Or they can move the information around, so that the date of the option remains set, but the date of the news is different.”

The study spotlights the relationship between late reporting of option grants, known as backdating, and subsequent stock-price gains. In a typical case, positive news that shoots up a stock’s price may add value to options granted when shares had been depressed by preceding negative news.

Backdating occurs when an executive picks an options grant date after the actual date has been announced and reports that instead of the original date to the Securities and Exchange Commission. The aggressive use of this practice allows insiders to look at past stock activity and choose a date that is the most beneficial for them.

In the study, the professors found that stock prices dropped nearly 4% in the three months before option grant dates and soared more than 9% in just as many months following the grant announcements. But the elastic structure of the reporting process is also partly to blame, according to Seyhun.

“A lot of executives don’t comply with the two-day requirement,” he said, referring to a SOX provision to report option grants within two days of the grant date. “And it’s not because they forgot, but because they’re playing this game.”
