The government has no timeline to divest of General Motors, and will probably do so steadily after the new company goes public.

Ron Bloom, one of the top leaders of the auto task force, said the government will sell off its 60 percent stake in GM gradually after the company has its initial public offering (IPO).

"We would expect that would likely happen in 2010. And then after that, there will be an orderly process in which these shares will be disposed of," Bloom told members of the Senate Banking Committee during testimony on Capitol Hill Wednesday afternoon. "Once we've become a shareholder, we certainly want to achieve fair value for those shares."

Bloom said the government had no specific target as to how many years the government would like to remain invested in GM, but said the government would likely not sell out of the automaker all at once out of concern for the seismic effect of such a sell-off.

"There will be a strategy to get out: it will be to access the public markets, and sell when the time comes to be selling," Bloom said.

The former union official also insinuated that the government had little choice but to take an equity stake in GM in terms of options it had to assist the company.

Bloom said that the company could scarcely afford to issue more debt, seeing as excessive debt was key to GM's problems in the first place.

"The president did not start out with wanting to be a shareholder. But one of these company's core problems for a lot of years was that it was too highly leveraged," Bloom testified. "We were very mindful of setting up General Motors of setting up a clean balanced sheet."
