The presentation of core earnings is designed to more closely align the timing of recognizing the actual value lost from prepayments in the mortgage servicing segment with the associated value created through new originations in the mortgage production segment. The Company believes that it will likely replenish most, if not all, realized value lost from changes in value from actual prepayments through new loan originations and actively manages and monitors economic replenishment rates to measure its ability to continue to do so. Therefore, management does not believe the unrealized change in value of the mortgage servicing rights is representative of the economic change in value of the business as a whole.Core earnings metrics are used in managing the Company’s mortgage business. The Company has also designed certain management incentives based upon the achievement of core earnings targets, subject to potential adjustments that may be made at the discretion of the Human Capital and Compensation Committee of the Company’s Board of Directors. Limitations on the use of Core Earnings Since core earnings or loss (pre-tax and after-tax) and core earnings or loss per share measure the Company’s financial performance excluding unrealized changes in value of mortgage servicing rights, such measures may not appropriately reflect the rate of value lost on subsequent actual payments or prepayments over time. As such, core earnings or loss (pre-tax and after-tax) and core earnings or loss per share may tend to overstate operating results in a declining interest rate environment and understate operating results in a rising interest rate environment, absent the effect of any offsetting gains or losses on derivatives that are intended to offset changes in fair value on the Company’s mortgage servicing rights. Adjusted cash flow Adjusted cash flow measures the Company’s Net increase or decrease in cash and cash equivalents for a given period excluding changes resulting from the issuance of equity, the purchase of derivative securities related to the Company’s stock or the issuance or repayment of unsecured or other debt by PHH Corporation. The Company believes that Adjusted cash flow is a useful measure for investors because the Company’s ability to repay future unsecured debt maturities or return capital to equity holders is highly dependent on a demonstrated ability to generate cash. Accordingly, the Company believes that Adjusted cash flow may assist investors in determining the amount of cash and cash equivalents generated from business activities during a period that is available to repay unsecured debt or distribute to holders of the Company’s equity.
