Yes BAC would. Fannie and Freddie are duopolistic in nature and have the majority of the market. That limits the future p/e because you can't gain more market share when you essentially control most of it. The risk is actually in including more competition.
It wouldn't make sense to do that anyway: none of the cases are class actions. Any settlement proceeds would only go to named plaintiffs, whereas Nomura's report is aimed at those thinking about buying FnF stock today.
It's certainly in the right ballpark. While they get to their number in a different way than I do, they arrive at right around the same place.
No, this isn't what Nomura meant at all. They think the re-IPO will happen at $5. $10 is off the table in their scenario.
BAC because their business is not as restricted as FnF's by regulations/regulators and charters.
