The time has come to end the debate on accounting for stock options; the controversy has been going on far too long. In fact, the rule governing the reporting of executive stock options dates back to 1972, when the Accounting Principles Board, the predecessor to the Financial Accounting Standards Board (FASB), issued APB 25. The rule specified that the cost of options at the grant date should be measured by their intrinsic value—the difference between the current fair market value of the stock and the exercise price of the option. Under this method, no cost was assigned to options when their exercise price was set at the current market price.
