Prosper customer support responded today:
As part of our continuing refinements in risk modeling for peer-to-peer lending, we are proposing the implementation of maximum loan amounts based on a borrower’s Prosper Rating. As with all SEC filings, the proposed changes will not be implemented until the S-1 amendment has been accepted by the SEC and deemed effective.
This response is clear and makes sense.
I don't agree with their notion that they would need to wait for the SEC to ok them to put additional restrictions on borrowers.
How do we know when a "post effective amendment" becomes "effective" ?
