I think the $10M liability from class action suit has been absorbed in the "operating activities" as stated below (p. 35 of 10-Q):
Net cash used in operating activities was $11,974 and $8,355 for the six months ended June 30, 2013 and 2012, respectively. The increase in cash used in operating activities was primarily attributable to the net loss offset by the class action settlement liability.
So the available cash should be net of this $10M liability.
The $1M net income I referred to before was from "Condensed Statements of Operations" (p. 20). This is actually a good news, since Prosper is now operationally profitable.
I still don't understand why Prosper is penny-pinching on the IRA fees, though.
