Mark-to-market adjustments(2) | (164 | ) |  |  | 196 |  |  | (160 | ) |  | (177 | )
Counterparty revenue share(3) | (68 | ) |  |  | (111 | ) |  | (230 | ) |  | (298 | )
Amortization, net of accretion(4) | (64 | ) |  |  | (112 | ) |  | (242 | ) |  | (314 | )
Total servicing revenue | $ | 236 |  |  |  | $ | 740 |  |  | $ | 766 |  |  | $ | 753 |
(1) | Amounts include subservicing related revenues.
(2) | Mark-to-market (“MTM”) adjustments include fair value adjustments on MSR, excess spread financing and MSR financing liabilities. The amount of MSR MTM includes the impact of negative modeled cash flows which have been transferred to reserves on advances and other receivables. The negative modeled cash flows relate to advances and other receivables associated with inactive and liquidated loans that are no longer part of the MSR portfolio. The impact of negative modeled cash flows was $25 for the five months ended December 31, 2018. The impact of negative modeled cash flows for the Predecessor was $38 for the seven months ended July 31, 2018 and $72 and $81 for the years ended December 31, 2017 and 2016, respectively.
(3) | Counterparty revenue share represents the excess servicing fee that the Company pays to the counterparties under the excess spread financing arrangements and the payments made associated with MSR financing arrangements.
(4) | Amortization for the Successor is net of excess spread accretion of $53 and MSL accretion of $15 for the five months ended December 31, 2018. Amortization for the Predecessor is net of excess spread accretion of $78 for the seven months ended July 31, 2018, and $161 and $200 for the years ended December 31, 2017 and 2016, respectively. The Predecessor recorded MSL accretion within reverse servicing fees, whereas the Successor has elected to record MSL accretion within Amortization, net of accretion.
