Facebook released the amount of shares allocated to each of its underwriters today, following its less-than-stellar IPO day.

The company went public on the Nasdaq to an EKG-like performance, ending in a .38 cent gain today. The update came in an amendment to the company's prospectus following the close of the market. Along with Facebook's tumultuous trading, a number of other tech companies' share prices fell today, including Zynga's which had to be halted.
