EI, you have a pretty good grasp of the situation but I must correct your statement:
"Once all of the claims are paid, WMILT assets revert back to the company."
Unless I'm missing context of which you speak - all claims include the final tranche which does not have a cap on it. Other than a small percent WMIH (Newco) (Is this the "company" you refer to you?) will only receive a very small amount. Excess assets after current claims are paid go to holders of old WAMPQ, WAMKQ or WAMUQ.
This post is my own opinion, and should not be relied on for your investment decisions.
