It is nothing more than the market maker's price for buying shares when there is nobody else looking to buy.
The market maker's job is to provide liquidity and an active market for the shares. In the event that there is no bid or ask, the market maker is free to set them to whatever he wants for buying your shares or selling shares to you. Buyers and sellers are perfectly able to trade inside that range if they want to. However, as we saw on Friday, if there is nobody that wants to take the shares and you definitely want to get out, then you take what the market maker is offering.
The "major" bid is just the market maker saying he'll take whatever anyone wants to sell...for his price.
It's actually probably better than that. Investors sometimes look to "steal" shares after hours at ridiculous levels as some weak hands cave just to end the pain. Should open better than that tomorrow, pending foreign markets overnight. China seems really to be teetering.
