Although some of our contracts and assignments are recurring in nature, and include repetitive monthly assignments, a significant portion of our engagements are transactional in nature and may be performed in connection with securitizations, loan sales, loan purchases or other transactions. Due to the transactional nature of our business, our Services segment revenues may fluctuate from period to period as transactions are commenced or completed. We do not recognize revenue or expense related to amounts advanced by us and subsequently reimbursed by clients for maintenance or repairs because we do not take control of the service prior to the client taking control.

We also use fixed-price contracts in our surveillance business for our servicer oversight services and RMBS surveillance services, and in our asset management business activities. Under fixed-price contracts we agree to perform the specified services and deliverables for a pre-determined per-unit or per-file price or day rate. Each service qualifies as a separate performance obligation and revenue is recognized as the service performed is made available to the client.</span></div><div style="line-height:120%;padding-top:6px;text-align:left;text-indent:30px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Time-and-Expense Contracts.</span><span style="font-family:inherit;font-size:10pt;"> The Services segment also derives a portion of its revenue from professional service activities under time-and-expense contracts. In these types of contracts, we are paid a fixed hourly rate, and we are reimbursed for billable out-of-pocket expenses as work is performed. These contracts are used in our loan review, underwriting and due diligence services.

	us-gaap	Description Of New Accounting Pronouncements Not Yet Adopted DescriptionOfNewAccountingPronouncementsNotYetAdopted	Accounting Standards Not Yet Adopted. <span style="font-family:inherit;font-size:10pt;">In February 2016, the FASB issued an update that replaces the existing accounting and disclosure requirements for leases of property, plant and equipment. The update requires lessees to recognize, as of the lease commencement date, assets and liabilities for all leases with lease terms of more than 12 months, which is a change from the current GAAP requirement to recognize only capital leases on the balance sheet. Pursuant to the new standard, the liability initially recognized for the lease obligation is equal to the present value of the lease payments not yet made, discounted over the lease term at the implicit interest rate of the lease, if available, or otherwise at the lessee’s incremental borrowing rate. The lessee is also required to recognize an asset for its right to use the underlying asset for the lease term, based on the liability subject to certain adjustments, such as for initial direct costs. Leases are required to be classified as either operating or finance, with expense on operating leases recorded as a single lease cost on a straight-line basis. For finance leases, interest expense on the lease liability is required to be recognized separately from the straight-line amortization of the right-of-use asset. Quantitative disclosures are required for certain items, including the cost of leases, the weighted-average remaining lease term, the weighted-average discount rate and a maturity analysis of lease liabilities. Additional qualitative disclosures are also required regarding the nature of the leases, such as basis, terms and conditions of: (i) variable interest payments; (ii) extension and termination options; and (iii) residual value guarantees. This update, and the clarifying update issued in July 2018, is effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The new standard must be adopted by applying the new guidance as of the beginning of the earliest comparative period presented, using a modified retrospective transition approach with certain optional practical expedients. We are currently in the process of identifying our current leases that are subject to the scope of this standard and evaluating the impact on our financial statements and future disclosures as a result of this update. We expect to recognize right-of-use assets and related obligations upon adoption of this update. In July 2018 the FASB issued a further update containing certain targeted improvements to the accounting and disclosure requirements for leases, including an additional (and optional) transition method to recognize the cumulative-effect adjustment as of the beginning of the period of adoption, rather than recognizing the cumulative-effect adjustment as of the beginning of the earliest comparative period presented. We expect to elect the optional transition method to recognize the cumulative-effect adjustment as of the beginning of the period of adoption. In addition, we expect to elect the practical expedients for transitioning existing leases to the new standard as of the effective</span><div style="line-height:120%;padding-top:6px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"> date. As a result of applying the practical expedients: (i) we are not required to reassess expired or existing contracts to determine if they contain additional leases; (ii) we are not required to reassess the lease classification for expired and existing leases; and (iii) we are not required to reassess initial direct costs for existing leases. We are currently evaluating the impact of adoption of these updates on our financial statements and future disclosures. See Note 13 of Notes to Consolidated Financial Statements in our 2017 Form 10-K for additional information about our leases.</span></div><div style="line-height:120%;padding-top:6px;text-align:left;text-indent:29px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In June 2016, the FASB issued an update to the accounting standard regarding the measurement of credit losses on financial instruments. This update requires that financial assets measured at their amortized cost basis be presented at the net amount expected to be collected. Credit losses relating to available-for-sale debt securities are to be recorded through an allowance for credit losses, rather than a write-down of the asset, with the amount of the allowance limited to the amount by which fair value is less than amortized cost. This update is effective for public companies for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. This update is not applicable to credit losses associated with our mortgage insurance policies. We are currently evaluating the impact on our financial statements and future disclosures as a result of this update. </span></div><div style="line-height:120%;padding-top:6px;text-align:left;text-indent:29px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In March 2017, the FASB issued an update to the accounting standard regarding receivables. The new standard requires certain premiums on purchased callable debt securities to be amortized to the earliest call date. The amortization period for callable debt securities purchased at a discount will not be impacted. The provisions of this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. We do not expect the adoption of this update to have a material effect on our financial statements and disclosures.</span></div><div style="line-height:120%;padding-top:6px;text-align:left;text-indent:30px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In August 2018, the FASB issued an update to the accounting standard regarding the accounting for long-duration insurance contracts. The new standard: (i) requires that assumptions used to measure the liability for future policy benefits be reviewed at least annually; (ii) defines and simplifies the measurement of market risk benefits; (iii) simplifies the amortization of deferred acquisition costs; and (iv) enhances the required disclosures about long-duration contracts. This update is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the potential impact of the adoption of this update.</span></div><div style="line-height:120%;padding-top:6px;text-align:left;text-indent:30px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In August 2018, the FASB issued an update to the accounting standard regarding the disclosure requirements for fair value measurement. The amendments in this update remove certain disclosure requirements regarding transfers between assets as well as the valuation process for Level III assets. This update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. An entity is permitted to early adopt any removed or modified disclosures and delay adoption of the additional disclosures until their required effective date. We are currently evaluating the impact on our financial statements and future disclosures as a result of this update. </span></div>In August 2018, the FASB issued an update to the accounting standard regarding the capitalization of implementation costs for activities performed in a cloud computing arrangement that is a service contract. The new standard aligns the accounting for implementation costs of hosting arrangements that are service contracts with the accounting for capitalizing internal-use software. This update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. We are currently evaluating the potential impact of the adoption of this update and do not expect it to have a material effect on our financial statements and disclosures.
