(1)MSRs transferred in transactions which do not qualify for sale accounting treatment. Until such time as the transaction qualifies as a sale for accounting purposes, we continue to recognize the MSRs and the related financing liability (referred as Pledged MSR liability) on our consolidated balance sheets, as well as the full amount of servicing fee collected as revenue and the servicing fee remitted as Pledged MSR liability expense in our consolidated statements of operations. The fair value of the Pledged MSR liability may differ from the fair value of the associated transferred MSR asset mostly due to the portion of ancillary income that is contractually retained by PHH or other contractual cash flows. (2)Consists of the obligation to remit to third parties a specified percentage of future servicing fee collections (servicing spread) on reference pools of MSRs, which we are entitled to as owner of the related MSRs. The servicing spread remittance is reported in Pledged MSR liability expense and fair value gains and losses of the ESS financing liability are reported in MSR valuation adjustment, net - See Note 9 – MSR Valuation Adjustments, Net.
