For old note holders-
I think the key question in the event of a Prosper bankruptcy is whether we can ask the bankruptcy judge to order Prosper to give us the identities and contact information of the borrowers so we can service the loans ourselves or transfer the servicing to someone else.
If Prosper only has the right to keep the identities and contact info of the borrowers from us so long as it is performing on its side of the contract, and breaching its contract or going out of business ends its right to keep those identities and info secret from us, then we really and truly are the owners of the loans, because we'll have the ability to terminate the servicing contract and take our servicing business to someone else if we want.
However, if Prosper has the right to keep the identities and contact info of the borrowers from us even if it breaches and fails to perform on the servicing contract and can take that info to its grave, then it owns the loans for all intents and purposes. Without the identities and contact info of the borrowers we have no ability to collect on the loans. Without an ability to collect on the loans ourselves if Prosper is unable or unwilling to do so for us, we wouldn't own them in any meaningful way.
It's as simple as that.
