Boston - Federal authorities have launched an investigation into a stock option grant made to Apple CEO Steve Jobs, The Wall Street Journal reported on Friday, citing "sources familiar with the probe."

The investigation stems from a "backdated" grant that carries a false date of October 2001. The changing of the date on which the options were granted increased their value for Jobs, compelling Apple to take a $20 million charge.

Apple has taken a total charge of $84 million in connection with 6,400 misdated stock options, in connection with an investigation by the SEC and U.S. Attorney's Office in Northern California.

Over 160 companies, including many in Silicon Valley, have either launched internal investigations or are the subjects of federal probes relating to "backdating" stock options.
