Prosper.com, which is still in quiet period and not allowing new loans, made a new SEC filing yesterday. In this third amendment to the S-1 filing makes several amendments, most notably introducing securitization for initial offerings of loans.

Prosper plans “Open market loans”, which apparently are loans issued by traditional lenders which being securitized and resold to Prosper lenders. I am somewhat sceptical how many Prosper lenders will like the “open market loans” offer. To me this seems a far excursion from the peer to peer lending idea.

In the filing Prosper states that FolioFn will be the operator of the Prosper secondary market (named “Folio Investing Note Trader Platform”). FolioFn already operates the Note Trading Platform of Lending Club.

More changes in the new filing are in a review in this blog post at P2PLendingNews.
