The Texas man federal officials accused in September of insider trading before Dell Inc.’s acquisition of Perot Systems Corp. agreed to return $8.6 million he earned from the trade.

The U.S. Securities and Exchange Commission disclosed that former Perot Investments Inc. employee Reza Saleh agreed to pay as a partial resolve to allegations. Perot Investments is a common affiliate with private company Perot Systems Corp.

SEC officials will also ask a Dallas federal court to impose a civil fine against Saleh.

Saleh, 53, bought 9,332 Perot call option contracts through two TD Ameritrade brokerages from Sept. 4-18, a decision regulators said was based on the impending $3.9 billion acquisition by Round Rock-based Dell (Nasdaq: DELL).

Dell, the No. 3 computer maker in the world, employs 16,000 workers in Central Texas.   The

acquisition, the largest in Dell’s history, was completed in November.
