Incremental Secured Facility

On January 31, 2013, Walter Investment Management Corp. (the “Company”) entered into the Amendment No. 1, Incremental Amendment and Joinder Agreement (the “Incremental Amendment”), to its Credit Agreement, dated as of November 28, 2012 (the “Secured Credit Agreement”), among the Company, the lenders party thereto, Credit Suisse AG, as administrative agent and collateral agent, and the other parties party thereto. The Incremental Amendment, among other things, increases certain financial ratios which govern the Company’s ability to incur additional indebtedness and provides for a secured term loan (the “Incremental Secured Credit Facility”) in an amount of $825.0 million, which was borrowed in its entirety on January 31, 2013. The Incremental Secured Credit Facility, which ranks pari passu in right of payment and is secured on a ratable basis with the existing loans under the Company’s Secured Credit Agreement, bears interest at a rate per annum equal to, at the option of the Company, LIBOR plus 4.50%, with a LIBOR “floor” of 1.25%, or an Alternate Base Rate plus 3.50% and matures on November 28, 2017. All other material terms of the loans under the Incremental Secured Credit Facility are consistent with the terms of the existing term loans under the Company’s Secured Credit Agreement.

The proceeds of the Incremental Secured Credit Facility were used, in part, together with cash on hand (including net proceeds received from the October 2012 offering of our common stock), to finance the acquisition by the Company of the Walter Assets (as defined below) and the MSR Asset Acquisition (as defined below) described below under Item 2.01. The remaining amount borrowed may be used for other acquisitions and general corporate purposes.

The foregoing description of the Incremental Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Incremental Amendment, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Residential Capital, LLC Asset Acquisition

As previously disclosed in the Company’s Current Reports on Form 8-K dated October 25, 2012, November 8, 2012 and November 27, 2012, the Company entered into a Joint Bidding Agreement (“JBA”), dated October 19, 2012, with Ocwen Loan Servicing LLC to jointly bid to acquire the mortgage servicing and originations and capital markets platforms of Residential Capital, LLC (“ResCap”) in an auction sponsored by the U.S. Bankruptcy Court. Pursuant to the JBA, the Company agreed to acquire the rights and assume certain liabilities relating to all of ResCap’s Fannie Mae mortgage servicing rights and related advances, and ResCap’s mortgage originations and capital markets platforms (the “Walter Assets”).

The acquisition by the Company of the Walter Assets closed on January 31, 2013. The total consideration paid by the Company for the Walter Assets was $492 million (including a $15 million earnest money deposit previously paid by the Company) and was paid from borrowings under the Incremental Secured Credit Facility and cash on hand.

MSR Asset Acquisition

As previously disclosed in the Company’s Current Report on Form 8-K dated January 10, 2013, on January 6, 2013, the Company’s wholly owned subsidiary, Green Tree Servicing LLC (“Green Tree”), entered into a Mortgage Servicing Rights Purchase and Sale Agreement, by and between Green Tree, as purchaser, and Bank of America, National Association (“BANA”), as seller, whereby Green Tree will acquire from BANA the mortgage servicing rights and related assets relating to a portfolio of residential mortgage loans owned by Fannie Mae and having an unpaid principal balance (“UPB”) as of November 30, 2012 of approximately $93 billion (the “MSR Asset Acquisition”). Green Tree paid an earnest money deposit of $51.8 million on January 7, 2013.

The MSR Asset Acquisition closed on January 31, 2013 for a total purchase price of $517.1 million. Green Tree paid $206.7 million on January 31, 2013, representing 50% of the total consideration, net of the $51.8 million earnest money deposit previously paid by Green Tree, from borrowings under the Incremental Secured Credit Facility and cash on hand. The remaining 50% will be paid on each servicing transfer date in a pro rata amount, according to the UPB of the mortgage loans transferred on each such date (in each case, together with interest at the Federal funds rate).

The description in Item 1.01 of this Current Report on Form 8-K, including the exhibit incorporated therein, is incorporated in its entirety into this Item 2.03 by reference.
