This is taken from the below article - mentions breakup fee which would only be if the deal was going to be signed. Of the total purchase, the equity check is expected to be $880 million, consisting of about $700 million for the servicing rights and $180 million for the advances. About half the equity is coming from Nationstar and the rest from Newcastle Investment Corp, a mortgage REIT managed by Fortress, and other Fortress funds. There is a $72 million break-up fee and reimbursement of up to $10 million of transaction-related expenses if Nationstar does not win the auction.
There is a deal already signed. Certain creditors, ResCap, NCT etc. have approved a bankruptcy plan which includes the auction and also includes the breakup fee payout. I hope (and I would say it is so) that NCT also has an interest in the break up fee.
