General Motors Corp. is considering all options to cut costs, even moving out of its Detroit headquarters, but no decision has been made, chief executive Fritz Henderson said on Monday.

In a conference call with reporters, said the firm would consider selling plants, renegotiating its restructuring plan with the United Auto Workers ahead of a deadline on June 1 to avoid bankruptcy, he said in a conference call with reporters, according to Reuters.

GM’s headquarters in downtown Detroit are located at a complex of towers that includes various retail and hotel operations called the Renaissance Center. GM purchased the center for $625 billion in 1996 and has poured in millions of dollars to renovate the complex which was originally built in the 1970s.

As we look at the structure, look at the business, we're looking at everything, particularly as we slim down, Henderson said. At this point, I don't have anything to report. We don't have any such plans, but if we did it would be motivated by business rationale, which would be cost-efficiency and speed.
