Pixar is being investigated by the Securities and Exchange Commission over its stock option awards.

The animation studio owned by Burbank-based Walt Disney Co. said it has received inquiries over its awards practices from the SEC and the U.S. Justice Department. Disney’s board is conducting a review of the options, which were granted prior to the acquisition.

Disney acquired Pixar in May for about $8 billion in stock and reports surfaced a few weeks later about some problems with its stock option practices.

Pixar joins nearly 200 companies that either are under investigation or have started their own inquiries into whether their stock options were backdated to maximize the gain to company executives and/or board members.

Shares in Disney were down 10 cents to $34.42 in early trading Friday.
