It also provides for customary indemnification by each of the Company and the Underwriters against certain liabilities and customary contribution provisions in respect of those liabilities. The transaction contemplated by the Underwriting Agreement is expected to close on January 11, 2013.

The Common Stock is being sold pursuant to an effective automatic shelf registration statement filed with the Securities and Exchange Commission (File No. 333-182103). A copy of the Underwriting Agreement is filed as Exhibit 1.1 hereto and incorporated by reference herein.

On January 7, 2013, the Company filed a Current Report on Form 8-K (the “January 7 Form 8-K”) disclosing, among other things, (i) its entry into material agreements related to two investments in excess mortgage servicing rights (“Excess MSRs”) on residential mortgage servicing loans with unpaid principal balances of approximately $215 billion and $13 billion, respectively, (ii) the Company’s intention to pursue the spin-off certain of its residential real estate related investments from the rest of its assets by distributing shares of common stock of New Residential Investment Corp., which is currently a wholly-owned subsidiary of the Company, and (ii) the launch of the offering of Common Stock described above under Item 1.01. The January 7 Form 8-K attached as an exhibit pro forma financial information that showed the impact of the two Excess MSR transactions, the spin-off and the offering of Common Stock.
