Backdating
In the context of mutual funds, a feature allowing fundholders to use an earlier date on a letter of intent to invest in a mutual fund in exchange for a reduced sales charge, e.g. Giving retroactive value to purchases from the earlier date. In the context of corporate governance, the illegal practice of setting the date of options awarded as part of executive compensation to a period when the stock price was very low (rather than setting the date of the options on the date the award was made).
