As part of the Strategic Review, we have been evaluating options for our reverse mortgage business, including the possibility of selling some or all of its assets or pursuing alternative solutions for the business in collaboration with other parties. We cannot be certain whether or on what terms we will be able to consummate any transaction involving our reverse mortgage business or whether any such transaction would reduce our expected reverse mortgage losses. As of December 31, 2018, the net carrying value of our Reverse Mortgage segment securitized loan book was a net liability of approximately $60.9 million.
If our estimated liability with respect to interest curtailment obligations arising out of servicing errors is inaccurate, or additional errors are found, and we are required to record additional material amounts, there may be an adverse impact on our results of operations or financial condition.
Subsequent to the completion of our acquisition of RMS, we discovered a failure by RMS to record certain liabilities to HUD, FHA and/or credit owners related to servicing errors by RMS. FHA regulations provide that servicers meet a series of event-specific timeframes during the default, foreclosure, conveyance, and mortgage insurance claim cycles. Failure to timely meet any processing deadline may stop the accrual of debenture interest otherwise payable in satisfaction of a claim under the FHA mortgage insurance contract and the servicer may be responsible to HUD for debenture interest that is not self-curtailed by the servicer, or for making the credit owner whole for any interest curtailed by FHA due to not meeting the required event-specific timeframes.
We had a curtailment obligation liability of $68.7 million at December 31, 2018 related to the foregoing, which reflects management’s best estimate of the probable incurred claim. The curtailment liability is recorded in payables and accrued liabilities on the consolidated balance sheets. We assumed $46.0 million of this liability through the acquisition of RMS, which resulted in a corresponding offset to goodwill and deferred tax assets. During the year ended December 31, 2018, we recorded a provision (benefit), net of expected third-party recoveries, related to the curtailment liability of $(7.0) million. We have potential estimated maximum financial statement exposure for an additional $61.8 million related to similar claims, which are reasonably possible, but which we believe are primarily the responsibility of third parties (e.g., prior servicers and/or credit owners). Our potential exposure to a substantial portion of this additional risk relates to the possibility that such third parties may claim that we are responsible for the servicing liability or that we exacerbated an existing failure by the third party. The actual amount, if any, of this exposure is difficult to estimate and requires significant management judgment as curtailment obligations continue to be an industry issue. While we are pursuing, and will continue to pursue, mitigation efforts to reduce both the direct exposure and the reasonably possible third-party-related exposure, we cannot assure you that any such efforts will be successful.
We had a curtailment obligation liability of $31.1 million at December 31, 2018 related to Ditech Financial's mortgage loan servicing, which we assumed through an acquisition of servicing rights. We are obligated to service the related mortgage loans in accordance with Ginnie Mae requirements, including repayment to credit owners for advances and interest curtailment. The curtailment liability is recorded in payables and accrued liabilities on the consolidated balance sheets.
We cannot assure you that we will not discover additional facts resulting in changes to our estimated liability. To the extent we are required to record additional amounts as liabilities, there may be an adverse impact on our results of operations or financial condition.
See Item 3. Legal Proceedings and Note 29 to our Consolidated Financial Statements for additional information.
We may be unable to fund our HECM repurchase obligations, and/or face delays in our ability to make such repurchases, or we may be unable to convey repurchased HECM loans to the FHA, which could have a material adverse effect on our business, liquidity, financial condition and results of operations.
We issue HMBS collateralized by HECM loans we originated and HECM Tails. Under the Ginnie Mae HMBS program, we are required to repurchase a HECM loan from an HMBS pool we have issued when the outstanding principal balance of the HECM loan is equal to or greater than 98% of the maximum claim amount. There can be no assurance that we will have access to the funding necessary to satisfy our repurchase obligations, particularly if our actual repurchase obligations materially exceed our estimated repurchase obligations. See the Liquidity and Capital Resources section of Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations for additional information.
