This transaction is expected to close in the second half of 2018.

Note 26 — Subsequent Events

MSR Fair Value Election

Effective January 1, 2018, we elected fair value accounting for our MSRs previously accounted for using the amortization method, which included Agency MSRs and government-insured MSRs. This irrevocable election applies to all subsequently acquired or originated servicing assets and liabilities that have characteristics consistent with each of these classes. We recorded a cumulative-effect adjustment of $82.0 million (before income taxes) to retained earnings as of January 1, 2018 to reflect the excess of the fair value of the Agency MSRs over their carrying amount. The government-insured MSRs were impaired by $24.8 million at December 31, 2017; therefore, these MSRs are already effectively carried at fair value. We will subsequently measure these MSRs at fair value at each reporting date and report changes in fair value in earnings in the period in which the changes occur. At December 31, 2017, the UPB and net carrying value of Agency MSRs for which the fair value election was made was $24.0 billion and $203.7 million, respectively. At December 31, 2017, the UPB and net carrying value of government-insured MSRs for which the fair value election was made was $16.9 billion and $133.2 million, respectively.

Pending Acquisition of PHH

On February 27, 2018, we entered into an Agreement and Plan of Merger, dated as of February 27, 2018 (the Merger Agreement), with PHH Corporation, a Maryland corporation (PHH), and POMS Corp, a Maryland corporation and a wholly owned subsidiary of Ocwen (Merger Sub). PHH is a leading non-bank servicer with established servicing and origination recapture capabilities. Pursuant to the Merger Agreement, Merger Sub will merge with and into PHH (the Merger), with PHH surviving. As a result of the Merger, PHH will become a wholly owned subsidiary of Ocwen. The merger consideration to be paid in the acquisition will be approximately $360.0 million and is expected to be funded by a combination of PHH’s cash on hand and Ocwen’s cash on hand. The portion to be funded by Ocwen’s cash on hand is currently estimated to be approximately $74.0 million, including payment of certain transaction expenses at closing, based on financial information provided by PHH, internal analysis and using an assumed closing date of June 30, 2018. We also expect cash payments for integration and other transaction-related costs following the closing of the transaction.

Upon the closing of the transaction, Ocwen will also assume debt (at the subsidiary level) in the form of PHH’s outstanding senior unsecured notes. The aggregate principal amount of these notes is approximately $119.0 million, representing approximately $97.0 million of PHH’s 7.375% Senior Notes Due 2019 and approximately $22.0 million of PHH’s 6.375% Senior Notes Due 2021.

This transaction is expected to close in the second half of 2018.

Under the terms and subject to the conditions of the Merger Agreement, at the effective time of the Merger, each outstanding share of PHH common stock, par value $0.01 per share, will be converted into the right to receive $11.00 in cash.
