The IPO Board

[rocky822]

Lady, hoping for some help here. I have no experience with IPO's and was researching TRBN.

Here, I see that they were issuing 4 millions shares as of 10/18.
Trubion Pharmaceuticals, Inc. is offering 4,000,000 shares of its common stock. This is our initial public offering, and no public market currently exists for our shares.

Yet, here it shows almost 17 million outstanding.

Shares Outstanding 16,906,000

Then, I was wondering about the insider holdings:

Number of Insider Trades: 7 7
Number of Buys: 7 7
Number of Sells: 0 0
Net Activity: 3,802,516 3,802,516
Total Shares Traded: 3,802,516 3,802,516
Number of Shares Bought: 3,802,516 3,802,516
Number of Shares Sold: 0 0

So, I was originally confused as I was seeing 3.8 million held by insiders (out of 4 million) and couldn't figure out where Wyeth's 800k went.

Here's list of insiders.

I guess I'm missing something that shows where they upped their initial offering?

I'm actually just confused and am hoping you can steer me in the right direction. Thanks much!
