Intuit

(INTU) - Get Report

said Thursday it received a Justice Department subpoena related to the ongoing stock option probe hitting a wide swath of companies.

The financial-software maker said the U.S. Attorney for the Northern District of California is seeking documents related to its historical options practices. Intuit already had begun its own investigation into its past stock options procedures, and disclosed

earlier this month that the Securities and Exchange Commission had launched an informal inquiry into the matter.

The SEC and Justice Department have been looking into the practice of "backdating" options, or granting insiders options at share prices that were known after the fact to be short-term lows.

Intuit said it will cooperate fully with the U.S. Attorney's office. The company's shares were down $1.22, or 2%, to $58.78 in after-hours trading.
