General Motors Co. is probably under the process of planning of enlisting eight more banks as joint bookrunners following the initial regulatory filing for its stock offers, as informed by someone familiar with the matter.

It is expected that the firm will file a prospectus with the U.S. Securities and Exchange Commission in the early parts of the approaching week.

This filing would probably comprise JP Morgan and Morgan Stanley, which had been selected as the lead underwriters on the IPO.

With the banks toiling to get the lead underwriting space on the IPO, the fees offered by them were almost 2-2.5% of the size of the total offer made.

The lowest offer was brought in by Goldman Sachs with a mere 0.75% points, as informed by a few number of sources informed about the matter.

However, the United States Government, which possessed the sanction power over the selection of underwriters, was not so confident about giving a lead role to Goldman Sachs.

JP Morgan proposed to get its share of the underwriting fee in the firm’s stock instead of taking cash that was a literal factor in GM’s success.

The offer however was not taken in, and rejected.

Goldman Sachs and JP Morgan did not offer to comment anything on the matter.
