A senior General Motors Corp. (GM) executive said Tuesday that the company's global technology center will remain in Europe, even after the company shed control of most of its operations there.

Chief Financial Officer Ray Young said details had still to be worked out, and GM will work with Magna International Inc. (MGA) on the structure of the Opel/Vauxhall divisions.

Magna won German government backing to take control of the Opel business alongside two Russian partners, with GM retaining a minority stake.

Aside from production, Opel has a key role in GM's global product design, though Young said most of its focus right now was on products for the European market.

"We anticipate the [European] engineering center will continue to play a major role for us globally," said Young during a conference call with analysts, adding that U.S. product launches will be unaffected by the sale.

The auto maker's moves in the last decade to meld its global operations and ensure vehicles made around the world share common platforms and technologies have complicated its efforts to break off Opel.

GM's European unit has been important to the company's global product development, including heavily influencing designs of GM vehicles sold in the U.S.

"Clearly, collaboration [with Magna] will be essential," Young said.

He said GM and Magna will work together on a new structure for the Opel unit, which is being held in trusteeship and separate from the parent's U.S. bankruptcy filing.

Still unresolved, he said, are details of how GM would access patents and intellectual property through Magna.

Executives from Opel and Magna are expected to provide further details on the unit's structure at an employee presentation on Wednesday.

In his remarks, Young said GM wouldn't become a public company again before the second quarter of next year, and forecast it would emerge from bankruptcy protection with a "very healthy" cash balance.

He added that $14 billion is considered a healthy global cash balance, but didn't specify its cash position when the "new GM" emerges from bankruptcy.

Near-term cash burn is expected to rise because of plant shutdowns and an increased employee buyout program.
