Prosper files amended S1-registration statement with the SEC yesterday announced it’s new registration filing.

The SEC filing follows an earlier one from last year that apparently did not succeed. Some speculation on the reasons Prosper’s first filing was ill-fated are on Fred93’s blog.

According to the filing, the class action lawsuit against Prosper reported previously on this blog, is currently the only class action lawsuit by lenders stated in the filing.

The sections on ‘Government regulation’ (page 73) and ‘Risks Relating to Compliance and Regulation’ (page 32) state numerous other legal risks the Prosper business model might face in the future.

For the year 2007 the filing reports that Prosper marketplace incurred a net loss of 11.8 million US$ – but still had more than 20 million US$ in cash or cash equivalents on Dec. 31st, 2007.

The following quote shows that in many attempted listings Prosper was not able to verify the income of the borrowers:

For example between September 1, 2007 and August 31, 2008, we verified employment and income for only approximately 22.6% of borrowers. …

Of the borrowers undergoing income verification for the period from September 1, 2007 to August 31, 2008:

+ approximately 56.7% provided us with satisfactory responses and received a borrower loan;
+ approximately 37.7% did not provide satisfactory responses, or did not respond, and their listings were cancelled; and
+ approximately 5.9% either withdrew their listings, or failed to receive bids totaling the amount of their requested loan.

On a side note: The document also discloses that Prosper bought the domain in 2006 for a price of 603,659 US$ (page F-14), of which 320,000 was payed in cash.
