Facebook (FB) shares change hands at $44.10 in their final SharesPost auction, as the company shuts down private-exchange trading ahead of its IPO.

Separately, SharesPost rival SecondMarket is laying off 10% of its staff, as it copes with both Facebook's offering and a broader pickup in tech IPO activity.
