Options backdating is the practice of altering the date a stock option was granted, to a usually earlier (but sometimes later) date at 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
