Options backdating is the practice of altering the date a stock option was granted to an earlier or later date, usually a date on which the underlying stock price was lower. This is a way of repricing options to make them valuable or more valuable when the option "strike price" (the fixed price at which the owner of the option can purchase stock) is fixed to the stock price at the date the option was granted. Cases of backdating employee stock options have drawn public and media attention.
While options backdating is not always illegal, many options in corporations are granted to upper management. Backdating has been called "cheating the corporation in order to give the CEO more money than was authorized." and a way of "rewarding managers when stock prices fall". According to a study by Erik Lie, a finance professor at the University of Iowa, more than 2,000 companies used options backdating in some form to reward their senior executives between 1996 and 2002. In an "uncanny number of cases," the "companies granted stock options to executives right before a sharp increase in their stocks."
To be legal, backdating must be clearly communicated to the company shareholders, properly reflected in earnings, and properly reflected in tax calculations.
The SEC’s opinions regarding backdating and fraud were primarily due to the various tax rules that apply when issuing “in the money” stock options vs. the much different – and more financially beneficial – tax rules that apply when issuing “at the money” or "out of the money" stock options. Additionally, companies can use backdating to produce greater executive incomes without having to report higher expenses to their shareholders, which can lower company earnings and/or cause the company to fall short of earnings predictions and public expectations. Corporations, however, have defended the practice of stock option backdating with their legal right to issue options that are already in the money as they see fit, as well as the frequent occurrence in which a lengthy approval process is required.
