Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of the Company	Description of the Company We are a leading global property information, analytics and data-enabled services provider operating in North America, Western Europe and Asia Pacific. Our combined data from public, contributory and proprietary sources provides detailed coverage of property, mortgages and other encumbrances, property risk and replacement cost, consumer credit, tenancy, location, hazard risk and related performance information. We have more than one million users who rely on our data and predictive decision analytics to reduce risk, enhance transparency and improve the performance of their businesses. With our data as a foundation, we have built strong analytics capabilities and a variety of value-added business services to meet our clients’ needs for mortgage and automotive credit reporting, property tax, property valuation, tenancy, hazard risk, property risk and replacement cost, flood plain location determination and other geospatial data, analytics and related services. Clients rely on us to help identify and manage growth opportunities, improve performance and mitigate risk. We are also a party to various joint ventures under which we share control of the management of the operations with the other partner. We were originally incorporated in California in 1894, and were reincorporated in Delaware on June 1, 2010 immediately following a transaction that spun-off our financial services businesses, which we refer to as "the Separation" as more fully described below. Before June 1, 2010, we operated as The First American Corporation (“First American” or “FAC”). In connection with the Separation, we changed our name to CoreLogic, Inc. and began trading on the New York Stock Exchange under the symbol “CLGX.” As used herein, the terms "CoreLogic," the Company," "we," "our" and "us" refer to CoreLogic, Inc. and our consolidated subsidiaries, except where it is clear that the terms mean only CoreLogic, Inc. and not our subsidiaries. Separation Transaction On June 1, 2010, we completed the Separation under which we spun-off our financial services businesses into a new, publicly-traded, New York Stock Exchange-listed company called First American Financial Corporation (“FAFC”) through a distribution (the “Distribution”) of all of the outstanding shares of FAFC to the holders of our common shares, par value $1.00 per share, as of May 26, 2010. After the Distribution, we retained the information solutions businesses which we renamed CoreLogic Inc. as noted above. To effect the Separation, we entered into a Separation and Distribution Agreement (the “Separation and Distribution Agreement”) that governs our rights and obligations and FAFC regarding the Distribution. It also governs the on-going relationship between us and FAFC subsequent to the completion of the Separation and provides for the allocation of assets and liabilities between us and FAFC. In addition, we also entered into a Tax Sharing Agreement (the “Tax Sharing Agreement”) as described in Note 9 – Income Taxes . While we are a party to the Separation and Distribution Agreement and various other agreements relating to the Separation, we have determined that we have no material continuing involvement in the operations of FAFC.

Significant Accounting Policies

Significant Accounting Policies	12 Months Ended

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Principles of Consolidation The consolidated financial statements include our accounts and all controlled subsidiaries. All significant intercompany transactions and balances have been eliminated. Equity investments in which we exercise significant influence, do not control, and are not the primary beneficiary, are accounted for using the equity method. Investments in which we do not exercise significant influence over the investee are accounted for under the cost method. Client Concentration We generate the majority of our revenues from clients with operations in the U.S. residential real estate, mortgage origination and mortgage servicing markets. Approximately 43.0% , 33.5% , and 29.8% of our operating revenues for the year ended December 31, 2016, 2015 and 2014 , respectively, were generated from our ten largest clients who consist of the largest U.S. mortgage originators and servicers. Two of our clients accounted for 14.0% and 11.5% of our operating revenues for the year ended December 31, 2016 . Both our PI and RMW segments reported revenue from these two customers. No client accounted for 10.0% or more of our operating revenues for the years ended December 31, 2015 or December 31, 2014 . Out-of-Period Adjustment During the fourth quarter of 2016, we identified an error which overstated our provision for income taxes by $4.4 million and understated our provision for income taxes by $1.3 million , both reflected within continuing operations, for the years ended December 31, 2015 and 2014, respectively. We recorded a net out-of-period adjustment of $3.1 million to correct the error in the quarter ended December 31, 2016, which increased basic and diluted net income per share by $0.03 . We assessed the materiality of this error and concluded the error was not material to the results of operations or financial condition for the current or prior annual or interim periods presented. See further discussion in Note 9 – Income Taxes. During the first quarter of 2015, we identified an error which overstated our interest expense by $5.2 million ( $3.1 million , net of tax), reflected within continuing operations, for the year ended December 31, 2014. We recorded an out-of-period adjustment to correct the error in the quarter ended March 31, 2015, which increased basic and diluted net income per share by $0.03 . We assessed the materiality of this error and concluded the error was not material to the results of operations or financial condition for the current or prior annual or interim periods presented. Use of Estimates The preparation of financial statements in accordance with generally accepted accounting policies ("GAAP") requires management to make estimates and assumptions that affect the financial statements. Actual results could differ from the estimates and assumptions used. Cash Equivalents We consider cash equivalents to be all short-term investments that have an initial maturity of 90 days as of the date of purchase or less and are not restricted. Accounts Receivable Accounts receivable are generally due from mortgage originators and servicers, financial institutions, insurers, government and government-sponsored enterprises located throughout the United States and abroad. Credit is extended based on an evaluation of the client’s financial condition, and generally, collateral is not required. The allowance for doubtful accounts for all probable uncollectible receivables is based on a combination of historical data, cash payment trends, specific client issues, write-off trends, general economic conditions and other factors. These factors are continuously monitored by management to arrive at the estimate for the amount of accounts receivable that may be ultimately uncollectible. In circumstances where a specific client is unable to meet its financial obligations, we record a specific allowance for doubtful accounts against amounts due to reduce the net recognized receivable to the amount we reasonably believe will be collected. Marketable Securities Debt securities are carried at fair value and consist primarily of investments in obligations of various corporations and mortgage-backed securities. Equity securities are carried at fair value and consist primarily of investments in marketable common and preferred stock. We classify our publicly traded debt and equity securities as available-for-sale and carry them at fair value with unrealized gains or losses classified as a component of accumulated other comprehensive loss. In October 2016, we liquidated our debt security at par value and reversed $0.5 million of unrealized gain previously recorded in other comprehensive loss. We realized no gain or loss for this transaction. As of December 31, 2015 , our marketable securities consisted of investments in preferred stock totaling $22.7 million . Property and Equipment Property and equipment is recorded at cost and includes computer software acquired or developed for internal use and for use with our products. Software development costs include certain payroll-related costs of employees directly associated with developing software and payments to third parties for completed or developing software. We begin capitalizing qualifying software development costs on a project when the preliminary project stage is completed and management has authorized further funding for completion. Capitalization ends once a project is substantially complete and the software is ready for its intended use. Costs incurred in the planning and post-implementation phases of software developing are expensed as incurred. Depreciation on buildings and on furniture and equipment is computed using the straight-line method over estimated useful lives of 25 to 40 , and 3 to 10 years, respectively. Capitalized software costs are amortized using the straight-line method over estimated useful lives of 3 to 10 years. Leasehold improvements are amortized over the lesser of the estimated useful life or the lease term. Capitalized Data and Database Development Costs, Net Capitalized data and database development costs represent our cost to acquire or develop the proprietary databases of information for client use. The costs are capitalized from the time the third party data is acquired until the information is ready for use, assuming both the preliminary project stage is complete and management has authorized funding for the completion of the data project. Property and eviction data costs are amortized using the straight-line method over estimated useful lives of 5 to 20 years. The carrying value for the flood data zone certification was $55.4 million as of December 31, 2016 and 2015 . Because properly maintained flood zone databases have indefinite lives and do not diminish in value with the passage of time, no provision has been made for depreciation or amortization. We periodically analyze our assets for impairment. This analysis includes, but is not limited to, the effects of obsolescence, duplication, demand and other economic factors. See further discussion in Note 4 – Capitalized Data and Database Development Costs, Net. Restricted Cash Restricted cash is comprised of certificates of deposit that are pledged for various letters of credit secured by us and escrow accounts due to acquisitions and divestitures. We deem the carrying value to be a reasonable estimate of fair value due to the nature of these instruments. Purchase Accounting The purchase method of accounting requires companies to assign values to assets and liabilities acquired based upon their fair values at the acquisition date. In most instances, there are not readily defined or listed market prices for individual assets and liabilities acquired in connection with a business, including intangible assets. The determination of fair value for assets and liabilities in many instances requires a high degree of estimation. The valuation of intangible assets, in particular, is very subjective. We generally obtain third-party valuations to assist us in estimating fair values. The use of different valuation techniques and assumptions could change the amounts and useful lives assigned to the assets and liabilities acquired and related amortization expense. Goodwill We perform an annual impairment test for goodwill and other indefinite-lived intangible assets for each reporting unit every fourth quarter, or on an interim basis if an indicator of impairment is present. In assessing the overall carrying value of our goodwill and other intangibles, we could first assess qualitative factors to determine whether the fair value of a reporting unit is less than its carrying amount. Examples of such events or circumstances include the following: cost factors, financial performance, legal and regulatory factors, entity specific events, industry and market factors, macroeconomic conditions and other considerations. If we determine that it is more likely than not that the fair value of a reporting unit is less than its carrying value, then quantitative impairment testing is performed. We could also elect to perform a quantitative impairment test without first assessing qualitative factors. In analyzing goodwill for the quantitative impairment test, we use a combination of the income and market approach. If the fair value of the reporting unit exceeds its book value, then goodwill is not considered impaired and no additional analysis is required. However, if the book value is greater than the fair value, a second step must be completed to determine if the implied fair value of the goodwill exceeds its book value. This involves calculating an implied fair value of goodwill for each reporting unit that indicated impairment. If the carrying value of goodwill assigned to a reporting unit exceeds its implied fair value, an impairment loss is recorded for the excess. The valuation of goodwill requires assumptions and estimates of many critical factors including revenue growth, cash flows, market multiples and discount rates. In assessing the fair value of indefinite lived intangibles, we compare the fair value of the asset to its carrying value to determine if there is an impairment. If the fair value of the asset is less than its carrying value, an impairment loss is recorded. See further discussion in Note 6 – Goodwill, Net. Other Intangible Assets Our intangible assets consist of covenants not to compete, client lists and trade names. Each of these intangible assets is amortized on a straight-line basis over its useful life ranging from 2 to 20 years and is subject to impairment tests if an indicator of impairment is present. Long-Lived Assets Long-lived assets held and used include property and equipment, capitalized software and other intangible assets. Management uses estimated future cash flows (undiscounted and excluding interest) to measure the recoverability of long-lived assets held and used, at the asset group level, whenever events or changes in circumstances indicate that the carrying value of an asset may not be fully recoverable. If the undiscounted cash flow analysis indicates a long-lived asset is not recoverable, the impairment loss recorded is the excess of the carrying amount of the asset over its fair value. In addition, we carry long-lived assets held for sale at the lower of cost or market as of the date that certain criteria have been met. Investment in Affiliates Investments in affiliates are accounted for under the equity method of accounting when we are deemed to have significant influence over the affiliate but do not control or have a majority voting interest in the affiliate. Investments are carried at the cost of acquisition, including subsequent capital contributions and loans from us, plus our equity in undistributed earnings or losses since inception of the investment. The carrying value of investments in affiliates is written down, or impaired, to fair value when a decline in value is considered to be other-than-temporary. In making the determination as to whether an individual investment in an affiliate is impaired, we assesses the current and expected financial condition of each relevant entity, including, but not limited to, the entity’s anticipated ability to generate sufficient cash flows and the market conditions in the industry in which the entity operates. We recognized impairment losses of $23.4 million and $0.4 million on investment in affiliates for the years ended December 31, 2016 and 2014 , respectively. There were no losses recognized in 2015 . Mandatorily Redeemable Noncontrolling Interest Mandatorily redeemable noncontrolling interests for which there is a contractual requirement to purchase the interest are included as a liability of NZD $27.8 million , or $19.0 million , in our accompanying condensed consolidated balance sheet as of December 31, 2015 . In January 2016, we acquired the remaining 40.0% interest in New Zealand-based Property IQ Ltd. ("PIQ") and settled the mandatorily redeemable noncontrolling interest. As a result, there was no mandatorily redeemable noncontrolling interest balance as of December 31, 2016 . For the years ended December 31, 2015 and 2014 , we recorded $1.2 million and $1.3 million , respectively, of net income in connection with the redeemable noncontrolling interest. Revenue Recognition We derive our revenues principally from U.S. mortgage originators and servicers with good creditworthiness. Our product and service deliverables are generally comprised of data or other related services. Our revenue arrangements with our clients generally include a work order or written agreement specifying the data products or services to be delivered and related terms of sale including payment amounts and terms. The primary revenue recognition-related judgments we exercise are to determine when all of the following criteria have been met: (i) persuasive evidence of an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) our price to the buyer is fixed or determinable; and (iv) collectability is reasonably assured. For products or services where delivery occurs at a point in time, we recognize revenue upon delivery. These products or services include sales of tenancy data and analytics, credit solutions for mortgage and automotive industries, under-banked credit services, flood data and services and claims management. For products or services where delivery occurs over time, we recognize revenue ratably on a subscription basis over the contractual service period once initial delivery has occurred. Generally these service periods range from one to three years. Products or services recognized on a license or subscription basis include information and analytic products, property risk and replacement cost, flood database licenses, realtors solutions and lending solutions. For certain of our products or services, clients may also pay us upfront set-up fees, which we defer and recognize into revenue over the longer of the contractual term or expected client relationship period. Property tax processing revenues are comprised of periodic loan fees and life-of-loan fees. For periodic fee arrangements, we generate monthly fees at a contracted rate for as long as we service the loan. Loans serviced with a one-time, life-of-loan fee are billed once the loan is boarded to our tax servicing system in accordance with a client tax servicing agreement. Life-of-loan fees are then deferred and recognized ratably over the expected service period. The rates applied to recognize revenues assume a 10 -year expected life and are adjusted to reflect prepayments. We review the tax service contract portfolio monthly to determine if there have been material changes in the expected lives, deferred on-boarding costs, expected service period and/or changes in the number and/or timing of prepayments. Accordingly, we may adjust the rates to reflect current trends. Cost of Services Cost of services represents direct costs incurred in the creation and delivery of our products and services. Cost of services consists primarily of data acquisition costs, royalty fees, hardware and software expense associated with transaction processing systems, telecommunication and computer network expense and occupancy costs associated with facilities where these functions are performed by employees. Cost of services also includes client service costs, which include personnel costs to collect, maintain and update our proprietary databases, to develop and maintain software application platforms and to provide consumer and client call center support. Selling, General and Administrative Expenses Selling, general and administrative expenses consist primarily of personnel-related costs, selling costs, corporate costs, fees for professional and consulting services, advertising costs, uncollectible accounts and other costs of administration such as marketing, human resources, finance, legal and administrative roles. Income Taxes We account for income taxes under the asset and liability method, whereby we recognize deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases as well as expected benefits of utilizing net operating loss and credit carryforwards. We measure deferred tax assets and liabilities using enacted tax rates we expect to apply in the years in which we expect to recover or settle those temporary differences. We recognize in income the effect of a change in tax rates on deferred tax assets and liabilities in the period that includes the enactment date. We recognize the effect of income tax positions only if sustaining those positions is more likely than not. We reflect changes in recognition or measurement of uncertain tax positions in the period in which a change in judgment occurs. We recognize interest and penalties, if any, related to uncertain tax positions within income tax expense. Accrued interest and penalties are included within the related tax liability line in the accompanying consolidated balance sheet. We evaluate the need to establish a valuation allowance based upon expected levels of taxable income, future reversals of existing temporary differences, tax planning strategies and recent financial operations. We establish a valuation allowance to reduce deferred tax assets to the extent it is more-likely-than-not that some or all of the deferred tax assets will not be realized. Comprehensive Income Comprehensive income includes all changes in equity except those resulting from investments by owners and distributions to owners. Specifically, foreign currency translation adjustments, amounts related to supplemental benefit plans, unrealized gains and losses on interest rate swap transactions and unrealized gains and losses on investment are recorded in other comprehensive loss. The following table shows the components of accumulated other comprehensive loss, net of taxes as of December 31, 2016 and 2015 : 2016 2015 Cumulative foreign currency translation $ (118,071 ) $ (114,427 ) Cumulative supplemental benefit plans (6,267 ) (3,540 ) Net unrecognized losses on interest rate swap 1,920 (2,699 ) Net unrealized gains on marketable securities — 550 Accumulative other comprehensive loss $ (122,418 ) $ (120,116 ) Share-based Compensation Currently, our primary means of providing stock-based compensation is granting restricted stock units (“RSUs”) and performance-based restricted stock units (“PBRSUs”). The fair value of any grant is based on the market value of our shares on the date of grant and is generally recognized as compensation expense over the vesting period. We measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The cost is recognized over the period during which an employee is required to provide services in exchange for the award. We utilize the Monte-Carlo simulation method to estimate the fair value for any PBRSUs granted and the Black-Scholes model to estimate the fair value of stock options. We apply the straight-line single option method of attributing the value of stock-based compensation expense. As stock-based compensation expense recognized in results of operations is based on awards ultimately expected to vest, stock-based compensation expense has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. We apply the long-form method for determining the pool of windfall tax benefits. In addition, we have an employee stock purchase plan that allows eligible employees to purchase common stock of the Company at 85.0% of the closing price on the first or last day of each quarter, whichever is lower (which was updated for 2014 from the closing price on the last day of each quarter). We recognize an expense in the amount equal to the estimated fair value of the discount. See Note 13 –Share-based Compensation Plans for additional information related to stock options and RSUs. Foreign Currency The functional currencies of our foreign subsidiaries are their respective local currencies. The financial statements of the foreign subsidiaries are translated into U.S. dollars for consolidation as follows: (i) assets and liabilities at the exchange rate as of the balance sheet date, (ii) stockholders’ equity at the historical rates of exchange and (iii) income and expense amounts at average rates prevailing throughout the period. Translation adjustments resulting from the translation of the subsidiaries’ accounts are included in “Accumulated other comprehensive loss,” a separate component of stockholders’ equity. Gains and losses resulting from foreign currency transactions are included within “Selling, general and administrative expenses” and are not material to the results of operations. Earnings/(Loss) Per Share Basic earnings/(loss) per share is computed by dividing net income/(loss) available to our stockholders by the weighted-average number of common shares outstanding. The computation of diluted earnings per share is similar to the computation of basic earnings per share, except that the weighted-average number of common shares outstanding is increased to include the number of additional common shares that would have been outstanding if dilutive stock options had been exercised and RSUs and PBRSUs were vested. The dilutive effect of stock options and unvested RSUs and PBRSUs is computed using the treasury stock method, which assumes any proceeds that could be obtained upon the exercise of stock options and vesting of RSUs and PBRSUs would be used to purchase shares of common stock at the average market price for the period. The assumed proceeds include any purchase price the grantee pays, the hypothetical windfall tax benefit that we receive upon assumed exercise or vesting and the hypothetical average unrecognized compensation expense for the period. We calculate the assumed proceeds from excess tax benefits based on the “as-if” deferred tax assets calculated under stock-based compensation standards. Tax Escrow Disbursement Arrangements We administer tax escrow disbursements as a service to our clients in connection with our tax services business. These deposits are maintained in segregated accounts for the benefit of our clients. These deposits totaled $619.4 million and $340.3 million at December 31, 2016 and 2015 , respectively. Because these deposits are held on behalf of our clients, they are not our funds and, therefore, are not included in the accompanying consolidated balance sheets. These deposits generally remain in the accounts for a period of two to five business days. We record earnings credits from these investments to mitigate the cost of bank-related fees. Under our contracts with our clients, if we make a payment in error or fail to pay a taxing authority when a payment is due, we could be held liable to our clients for all or part of the financial loss they suffer as a result of our act or omission. We maintained claim reserves relating to incorrect disposition of assets of $22.2 million and $21.2 million as of December 31, 2016 and 2015 , respectively. Recent Accounting Pronouncements In November 2016, the Financial Accounting Standards Board (“FASB”) issued guidance providing that restricted cash and restricted cash equivalents are to be included with cash and cash equivalents on the statement of cash flows. The guidance is effective in fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Earlier adoption is permitted but we do not anticipate electing early adoption. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In October 2016, the FASB issued guidance pursuant to which an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Two common examples of assets transferred intra-entity are intellectual property and property, plant, and equipment. The guidance is effective in fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Earlier adoption is permitted but we do not anticipate electing early adoption. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In October 2016, the FASB issued guidance related to the consolidation of a variable interest entity (“VIE”). Indirect interests held through related parties that are under common control with the single decision maker are no longer required to be considered the equivalent of direct interests in their entirety. Instead, a single decision maker is required to include those interests on a proportionate basis consistent with indirect interests held through other related parties. The guidance is effective in fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In August 2016, the FASB issued guidance on eight specific cash flow classification issues that were either unclear or where no specific guidance was provided. The specific issues include i) debt prepayment or debt extinguishment costs; ii) settlement of zero-coupon debt instruments; iii) contingent consideration payments made after a business combination; iv) proceeds from the settlement of insurance claims; v) proceeds from the settlement of company-owned life insurance; vi) distributions received from equity method investees; vii) beneficial interests in securitization transactions; and, viii) separately identifiable cash flows and application of the predominance principle. The guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years and earlier adoption is permitted. We have elected early adoption and the guidance did not have a material impact on our consolidated financial statements. In June 2016, the FASB issued guidance for accounting of credit losses affecting the impairment model for most financial assets and certain other instruments. Entities will be required to use a new forward-looking current expected credit loss model for trade and other receivables, held-to-maturity debt securities, loans and other instruments, which will generally lead to an earlier recognition of loss allowances. Entities will recognize expected losses on available-for-sale debt securities as allowances rather than a reduction in amortized cost of the security while the measurement process of this loss does not change. Disclosure requirements are expanded regarding an entity’s assumptions, models and methods of estimations of the allowance. The guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Earlier adoption is permitted but we do not anticipate electing early adoption. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In March 2016, the FASB issued guidance to simplify some provisions in stock compensation accounting. The accounting for income taxes requires all excess tax benefits and tax deficiencies to be recognized through income tax expense. The statement of cash flows presentation of excess tax benefits should be classified with other income tax cash flows as an operating activity. An entity may also make an entity-wide election to either continue estimating the number of awards that are expected to vest or account for forfeitures as they occur. The requirements to qualify for equity classification permits tax withholding up to the maximum statutory tax rates in the applicable jurisdictions. Lastly, payments of cash by an employer for tax-withholding purposes, when directly withholding shares, are classified as a financing activity on the statement of cash flows. The guidance is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Earlier adoption is permitted but we did not elect early adoption. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In March 2016, the FASB issued guidance on equity method accounting related to joint venture investments. The standard eliminates the requirement to retroactively adopt the equity method of accounting as a result of an increase in the level of ownership or degree of influence related to an investment. The guidance is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Earlier adoption is permitted but we did not elect early adoption. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In March 2016, the FASB issued guidance on derivatives and hedging. The standard clarifies the four-step decision sequence required for assessing whether contingent put and call options that can speed up the payment for a debt instrument’s principal are clearly and closely related to the debt to which they are attached. The standard also clarifies that, provided all other hedge accounting criteria continue to be met, a change in the counterparty to a derivative instrument does not in itself disqualify designation of the hedge. The guidance is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Earlier adoption is permitted but we did not elect early adoption. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In February 2016, the FASB issued guidance on lease accounting. The standard requires all leases in excess of 12-months to be recognized on the balance sheet as lease assets and lease liabilities. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee have not changed significantly from prior GAAP. For operating leases, a lessee is required to i) recognize a right-of-use asset and lease liability, initially measured at the present value of the lease payment, ii) recognize a single lease cost over the lease term generally on a straight-line basis, and iii) classify all cash payments within operating activities on the cash flow statement. The guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Earlier adoption is permitted but we do not anticipate electing early adoption. We are currently evaluating the impact of the adoption of this guidance on our consolidated financial statements. In January 2016, the FASB issued guidance on accounting for equity investments and financial liabilities. The standard does not apply to equity method investments or investments in consolidated subsidiaries. The update provides that equity investments with readily determinable values be measured at fair value and changes in the fair value flow through net income. These changes historically have run through other comprehensive income. Equity investments without readily determinable fair values have the option to be measured at fair value or at cost adjusted for changes in observable prices minus impairment. Changes in either method are also recognized in net income. The standard requires a qualitative assessment of im

Equity Method Investments and Joint Ventures [Abstract]
Investment in Affiliates, Net	Investment in Affiliates, Net Investments in affiliates, net, were $40.8 million and $69.2 million as of December 31, 2016 and 2015 , respectively. We recorded $0.5 million , $13.7 million and $14.1 million of equity in earnings of affiliates, net of tax for the years ended December 31, 2016, 2015 and 2014 , respectively. Income tax expense of $1.0 million , $9.1 million and $8.9 million was recorded on those earnings for the years ended December 31, 2016, 2015 and 2014 , respectively. Dividends from equity method investments were $9.0 million , $30.1 million and $38.7 million for the years ended December 31, 2016, 2015 and 2014 , respectively. We recorded $10.3 million , $18.2 million and $19.0 million , respectively, of operating revenues and $11.2 million , $13.0 million and $12.9 million , respectively, of operating expenses related to transactions with our investment in affiliates for the years ended December 31, 2016, 2015 and 2014 . In December 2015, we completed the acquisition of the remaining 49.9% interest in RELS LLC ("RELS"), a leading nation-wide provider of real estate asset valuation and appraisal solutions, and recorded an investment gain of approximately $34.3 million due to the step-up in fair value on the previously held 50.1% interest, which is included in gain on investment and other, net in the accompanying consolidated statements of operations. See Note 16 - Acquisitions for additional information. Prior to the acquisition, RELS contributed 84.9% and 80.0% of our total equity in earnings of affiliates, net of tax, for the years ended December 31, 2015 and December 31, 2014 , respectively. Based on the terms and conditions of the joint venture agreement, we had significant influence but did not have control of, or a majority voting interest in, the joint venture. Accordingly, prior to the acquisition of the remaining 49.9% interest in RELS in December 2015, this investment was accounted for under the equity method. Due to the acquisition of RELS, equity in earnings of affiliates was not significant for the year ended December 31, 2016 . The following summarized financial information for this investment (assuming 100.0% ownership interest) is as follows: (in thousands) 2015 Balance sheet Total assets $ 42,164 Total liabilities 13,391 (in thousands) 2015 2014 Statements of operations Total revenues $ 244,647 $ 221,328 Expenses and other 205,891 183,761 Net income attributable to RELS LLC $ 38,756 $ 37,567 CoreLogic equity in earnings of affiliate, pre-tax $ 19,417 $ 18,821 In December 2016, we recorded a pre-tax non-cash impairment of $18.5 million related to our joint venture investment in Speedy Title & Appraisal Review Services LLC ("STARS"). The remaining STARS investment value is $3.0 million , and STARS rolls up into our PI segment. We recorded an additional pre-tax non-cash impairment loss of $4.9 million related to another equity method investment. In November 2016, we acquired 12.97% ownership of Onthehouse Holding Limited (“OTH”) through a non-cash transaction of AUD $11.3 million or $8.3 million . The consideration comprised of our investment in PropertyIQ Ltd. and a business line from our Australian operations. The transaction resulted in a gain of AUD $9.9 million , or USD $7.3 million , recorded in gain on investments and other, net in our accompanying consolidated statements of operations. In March 2014, we acquired certain equity interests, assets and intellectual property, which we collectively refer to as "MSB/DataQuick." See Note 16 - Acquisitions for additional information. The acquisition included a 29.4% interest in Symbility Solutions Inc. ("Symbility"). In connection with the purchase price allocation, we recorded $18.3 million to reflect our basis in Symbility. The purchase allocation included $11.3 million of basis difference between the purchase price and our interest in the net assets of Symbility, which is comprised of an indefinite-lived component of $2.0 million and a finite-lived component of $9.4 million with an estimated weighted-average life of 15 years.

We perform an annual goodwill impairment test for each reporting unit in the fourth quarter. In addition to our annual impairment test, we periodically assess whether events or circumstances occurred that potentially indicate that the carrying amounts of these assets may not be recoverable. We elected to perform a quantitative impairment test on our reporting units without first assessing qualitative factors. Determining the fair value of a reporting unit is judgmental in nature and requires the use of significant estimates and assumptions, including revenue growth rates, operating margins, discount rates and future market conditions, among others. Key assumptions used to determine the fair value of our reporting units in our testing were: (a) expected cash flow for the period from 2017 to 2022; and (b) discount rates of 8.5% and 9.0% for PI and RMW, respectively, which was based on management's best estimate of the after-tax weighted average cost of capital. Based on the results of our fourth quarter goodwill impairment test, the goodwill attributable to our reporting units is not impaired as of December 31, 2016 . It is reasonably possible that changes in the facts, judgments, assumptions and estimates used in assessing the fair value of the goodwill could cause a reporting unit to become impaired.

Credit Agreement In July 2016, we amended and restated our senior secured credit facility (the "Credit Agreement") with Bank of America, N.A., as administrative agent, and other financial institutions. The Credit Agreement provides for a $1.3 billion term loan facility (the "Term Facility") and a $550.0 million revolving credit facility (the "Revolving Facility"). The Term Facility matures and the Revolving Facility expires in April 2020. The Revolving Facility includes a $100.0 million multicurrency revolving sub-facility and a $50.0 million letter of credit sub-facility. The Credit Agreement also provides for the ability to request that the lenders increase the Term Facility by up to $225.0 million in the aggregate; however, the lenders are not obligated to do so. The loans under the Credit Agreement bear interest, at our election, at (i) the Alternate Base Rate (as defined in the Credit Agreement) plus the Applicable Rate (as defined in the Credit Agreement) or (ii) the London interbank offering rate for Eurocurrency borrowings, adjusted for statutory reserves, plus the Applicable Rate. The initial Applicable Rate for Alternate Base Rate borrowings is 0.75% and for Adjusted Eurocurrency Rate (as defined in the Credit Agreement) borrowings is 1.75% . Starting with the full fiscal quarter after the closing date, the Applicable Rate will vary depending on our leverage ratio. The minimum Applicable Rate for Alternate Base Rate borrowings will be 0.25% and the maximum will be 1.00% . The minimum Applicable Rate for Adjusted Eurocurrency Rate borrowings will be 1.25% and the maximum will be 2.00% . The Credit Agreement also requires us to pay commitment fees for the unused portion of the Revolving Facility, which will be a minimum of 0.25% and a maximum of 0.40% , depending on our leverage ratio. The Credit Agreement provides that loans under the Term Facility must be repaid in quarterly installments, commencing in September 2016 and continuing on each three-month anniversary thereafter in an amount equal to $17.2 million for the first four quarterly payments, $34.4 million for the next four quarterly payments and $51.6 million for each quarterly payment thereafter through March 2020. The outstanding balance of the Term Facility will be due in April 2020. The Credit Agreement contains financial maintenance covenants, including a (i) maximum total leverage ratio not to exceed 4.50 to 1.00 (stepped down to 4.25 to 1.00 starting with the fiscal quarter ending June 2017, with a further step down to 3.75 to 1.00 starting with the fiscal quarter ending June 2018 and stepped down to 3.50 to 1.00 starting with the fiscal quarter ending June 2019) and (ii) a minimum interest coverage ratio of not less than 3.00 to 1.00 . At December 31, 2016 , we had borrowing capacity under the Revolving Facility of $248.0 million and we were in compliance with all of our covenants under the Credit Agreement. 7.25% Senior Notes In May 20, 2011, we issued $400.0 million aggregate principal amount of 7.25% senior notes due 2021 (the "Notes"). In July 2016, we amended and increased by $525.0 million our Credit Agreement. We utilized approximately $411.0 million of the $525.0 million proceeds to complete the redemption of all outstanding Notes, which included a premium on debt extinguishment payment of $14.2 million for the year ended December 31, 2016 . Debt Issuance Costs In connection with the amendment and restatement of the Credit Agreement, we incurred approximately $6.3 million of debt issuance costs of which $0.3 million were expensed in the accompanying consolidated statements of operations. We capitalized the remaining $6.0 million of debt issuance costs within long-term debt, net in the accompanying consolidated balance sheets, and we will amortize these costs over the term of the Credit Agreement. We had unamortized costs of $14.0 million related to previously recorded debt issuance costs, which we will amortize over the term of the Credit Agreement. In connection with the redemption of the Notes in July 2016, we wrote-off $10.2 million of unamortized debt issuance costs for the year ended December 31, 2016 . For the year ended December 31, 2015 , we recorded $6.5 million of debt issuance costs of which $0.4 million were expensed in the accompanying consolidated statements of operations for the year ended December 31, 2015. We capitalized the remaining $6.1 million of debt issuance costs within long-term debt, net in the accompanying consolidated balance sheets. Further, we wrote-off $1.6 million of unamortized debt issuance costs during the year ended December 31, 2015 . 7.55% Senior Debentures In April 1998, we issued $100.0 million in aggregate principal amount of 7.55% senior debentures due 2028. In April 2010, in anticipation of the Separation, we commenced a cash tender offer for these debentures and also solicited consent from the holders thereof to expressly affirm that the Separation would not conflict with the terms of the debentures. See Note 15 - Litigation and Regulatory Contingencies for further discussion on the Separation. In April 2010, we announced that valid consents were tendered representing over 50.0% of the outstanding debentures. Accordingly, we received the requisite approvals from debenture holders and amended the related indentures. The indentures governing these debentures, as amended, contain limited restrictions on the Company. In November 2016, we paid down $45.0 million on the 7.55% senior debentures, which included a premium on debt extinguishment payment in the amount of $2.0 million for the year ended December 31, 2016 . Interest Rate Swaps We have entered into amortizing interest rate swaps (the "Swaps") in order to convert a portion of our interest rate exposure on the Term Facility floating rate borrowings from variable to fixed. In August 2016, we entered into Swaps which became effective in September 2016 and terminate in April 2020. The Swaps entered in August 2016 are for an initial notional balance of $500.0 million , with a fixed interest rate of 1.03% , and amortize quarterly by $25.0 million through December 2018, with a step up in the notional balance of $100.0 million in March 2019 and continued quarterly amortization of $25.0 million through April 2020. In May 2014, we entered into Swaps which became effective in December 2014 and terminate in March 2019. The Swaps entered in May 2014 are for an initial notional balance of $500.0 million , with a fixed interest rate of 1.57% , and amortize quarterly by $12.5 million through December 31, 2017 and $25.0 million through December 31, 2018. We have designated the Swaps as cash flow hedges. The estimated fair value of these cash flow hedges is recorded in other assets and/or other liabilities in the accompanying consolidated balance sheets. As of December 31, 2016 , we recorded an asset of $5.4 million and a liability of $2.3 million and as of December 31, 2015 , we recorded a liability of $4.4 million . For the years ended December 31, 2016, 2015 and 2014 , an unrealized gain of $4.6 million (net of $2.9 million in deferred taxes), an unrealized loss of $0.4 million (net of $0.2 million in deferred taxes), and an unrealized loss of $2.4 million (net of $1.5 million in deferred taxes), respectively, were recognized in other comprehensive income/(loss) related to the Swaps.

Additionally, due to the closure of the Internal Revenue Servies (IRS) audit for examination of the years 2005-2009, we recognized a net tax benefit of $14.4 million , including interest and penalties, for the year ended December 31, 2016 , which were accrued for and fully indemnified by FAFC. As of December 31, 2016 , we had an estimated $43.7 million of undistributed earnings from foreign subsidiaries that are intended to be indefinitely reinvested in foreign operations. No incremental U.S. tax has been provided for these earnings. If in the future, these earnings are repatriated to the U.S., or if we determine that the earnings will be remitted, additional tax provisions may be required. It is not practicable to calculate the deferred taxes associated with those earnings because of multiple factors that would need to be assessed at the time of assumed repatriation; however, foreign tax credits may be available to reduce federal income taxes in the event of distribution. Deferred Tax Assets and Liabilities Deferred income taxes arise from temporary differences between financial reporting and tax reporting bases of assets and liabilities, and operating loss and tax credit carryforwards for tax purposes. The components of the deferred income tax assets and liabilities as of December 31, 2016 and 2015 are as follows: (in thousands) 2016 2015 Deferred tax assets: Net losses and credit carryforwards $ 90,773 $ 92,537 Deferred revenue 149,022 132,359 Investment in affiliates 14,501 — Employee benefits 47,823 46,586 Accrued expenses and loss reserves 38,024 32,796 Other 20,693 1,042 Less: valuation allowance (44,880 ) (19,171 ) $ 315,956 $ 286,149 Deferred tax liabilities: Depreciable and amortizable assets 415,879 279,435 Investment in affiliates 18,624 11,199 Other — 4,658 $ 434,503 $ 295,292 Net deferred tax liability $ (118,547 ) $ (9,143 ) As of December 31, 2016 and 2015 , we had federal net operating losses (“NOLS”) of $176.6 million and $181.4 million , respectively, which begin to expire in 2021. The state NOLS were $271.1 million and $251.1 million as of December 31, 2016 and 2015 , respectively, which begin to expire in 2016. The foreign NOLS were $9.9 million and $12.8 million as of December 31, 2016 and 2015 , respectively. As of December 31, 2016 we had available federal and state capital losses of $17.8 million and $30.1 million , respectively, expiring at various times beginning in 2017. A portion of our NOL's and capital losses may be utilized prior to the expiration of carryover statutes. The change of ownership provisions of the Tax Reform Act of 1986 may limit utilization of a portion of our domestic NOL and tax credit carryforwards to future periods. As of December 31, 2016 and 2015 , we had valuation allowances of approximately $44.9 million and $19.2 million , respectively, against certain U.S. and foreign deferred tax assets. The increase in the valuation allowance was primarily due to deferred tax assets of $17.5 million that were capital in nature, a release of approximately $4.0 million on various domestic tax attributes that are more likely than not to be realized and the impact of the foreign out-of-period adjustment of $12.2 million . The increase in the valuation allowance due to the foreign deferred tax out-of-period adjustment of $12.2 million was offset by a $15.3 million benefit related to a reduction in foreign deferred tax liabilities resulting in a net out-of-period benefit to the tax provision of $3.1 million . See Note 2 - Significant Accounting Policies for additional information on out-of-period adjustment. Unrecognized Tax Benefits A reconciliation of the unrecognized tax benefits for the years ended December 31, 2016 , 2015 and 2014 are as follows: (in thousands) 2016 2015 2014 Unrecognized tax benefits - opening balance $ 34,301 $ 35,663 $ 55,325 Gross increases - tax positions in prior period 1,835 13 2,950 Gross decreases - tax positions in prior period (106 ) (2,152 ) (22,698 ) Gross increases - current-period tax positions 528 896 651 Settlements with taxing authorities (17 ) (119 ) (565 ) FAFC indemnification release (13,147 ) — — Expiration of the statute of limitations for the assessment of taxes (2,215 ) — — Unrecognized tax benefits - ending balance $ 21,179 $ 34,301 $ 35,663 As of December 31, 2016 and 2015 , our unrecognized tax benefits of $21.2 million and $34.3 million , respectively, include $13.0 million and $13.3 million , respectively, of unrecognized tax benefits that, if recognized, would have an impact on the effective tax rate. We recognize a provision for interest and penalties related to uncertain tax positions in income tax expense. As of December 31, 2016 and 2015 , we had $9.3 million and $17.3 million , respectively, accrued for the payment of interest and penalties. These balances are gross amounts before any tax benefits and are included in other liabilities in the accompanying consolidated balance sheets. For the years ended December 31, 2016, 2015 and 2014 , we recognized approximately $0.7 million , $0.2 million and $0.6 million , respectively, in interest and penalties in the accompanying consolidated statements of income. In November, 2016, we closed our 2005-2009 IRS exam which resulted in a reversal of approximately $13.2 million of unrecognized tax benefits and a reversal of approximately $8.7 million of accrued interest and penalties. These reversals reduced the total FAFC indemnification receivable to $14.0 million pursuant to the Tax Sharing Agreement entered in connection with the Separation. The remaining reserves subject to indemnification of $8.3 million and the associated accrued interest and penalties of $5.7 million are related to various taxing jurisdictions for the years 2006-2009. Any future decrease in this reserve would not have a material impact to net income. We are currently under examination for the tax years 2006 through 2011 by the U.S., our primary taxing jurisdiction, and various taxing authorities. It is reasonably possible the amount of the unrecognized benefit with respect to certain unrecognized positions that are not subject to the FAFC indemnification could significantly increase or decrease within the next twelve months and would have an impact on net income.

Compensation and Retirement Disclosure [Abstract]
Employee Benefit Plans	Employee Benefit Plans We currently offer a variety of employee benefit plans, including the CoreLogic, Inc. 401(k) Savings Plan (the "Savings Plan"), a defined benefit pension plan incorporated with the acquisition of RELS (the "RELS Pension Plan"), non-qualified plans and a deferred compensation plan. RELS voted to terminate the RELS Pension Plan effective October 31, 2016. The RELS Pension Plan offers participants annuity payments based on a number of factors and will offer an alternative lump sum distribution to certain participants. After certain regulatory approvals are obtained (i) we will provide additional cash contributions to the RELS Pension Plan to ensure that sufficient assets are available to make lump sum distribution payments, (ii) purchase group annuity contracts from one or more highly rated insurance companies to pay and administer future benefit payments, and (iii) complete other transactions required to terminate the RELS Pension Plan in a manner that fully meets its obligations to all participants. The total amount of additional cash contributions required to be provided by us will depend upon changes in interest rates, RELS Pension Plan asset returns, the lump sum election rate, and other factors. To sufficiently fund the RELS Pension Plan, we made a $4.0 million cash contribution in December 2016 and expect to make an additional cash contribution of approximately $9.9 million in 2017. The non-qualified plans are comprised of our frozen unfunded supplemental management and executive benefit plans (collectively, “SERPs”) and a frozen pension restoration plan (the “Restoration Plan”). The non-qualified plans are exempt from most provisions of the Employee Retirement Income Security Act because they are only available to a select group of management and highly compensated employees and are therefore not qualified employee benefit plans. To preserve the tax-deferred savings advantages of a non-qualified plan, federal law requires that it be an unfunded or informally funded future promise to pay. The following table summarizes the balance sheet impact, including benefit obligations, assets and funded status associated with the RELS Pension Plan, SERPs and Restoration Plan as of December 31, 2016 and 2015 : (in thousands) 2016 2015 Change in projected benefit obligation: Benefit obligation at beginning of period $ 61,256 $ 32,259 Addition of RELS — 31,308 Service costs 90 161 Interest costs 2,587 1,205 Actuarial losses/(gains) 1,817 (1,797 ) Benefits paid (2,989 ) (1,880 ) Annuity carrier load 2,347 — Projected benefit obligation at end of period $ 65,108 $ 61,256 Change in plan assets: Plan assets at fair value at beginning of period $ 21,175 $ — Addition of RELS — 21,175 Actual return on plan assets (458 ) — Company contributions 7,497 1,880 Benefits paid (2,989 ) (1,880 ) Plan assets at fair value at end of the period 25,225 21,175 Reconciliation of funded status: Unfunded status of the plans $ (39,883 ) $ (40,081 ) Amounts recognized in the consolidated balance sheet consist of: Accrued benefit liability $ (65,108 ) $ (61,256 ) Pension plan asset $ 25,225 $ 21,175 $ (39,883 ) $ (40,081 ) Amounts recognized in accumulated other comprehensive loss: Unrecognized net actuarial loss $ 14,021 $ 11,363 Unrecognized prior service credit (4,486 ) (5,631 ) $ 9,535 $ 5,732 The net periodic pension cost for the years ended December 31, 2016 , 2015 and 2014 , for the RELS Pension Plan, SERPs, and Restoration Plan includes the following components: (in thousands) 2016 2015 2014 Expenses: Service costs $ 90 $ 161 $ 282 Interest costs 2,587 1,205 1,231 Expected return on plan assets (160 ) — — Amortization of net loss/(gain) 979 (620 ) (424 ) Net periodic benefit cost $ 3,496 $ 746 $ 1,089 Weighted-average discount rate used to determine costs for the plans were as follows: 2016 2015 2014 RELS Pension Plan 4.44 % 4.09 % N/A SERPs 4.20 % 3.85 % 4.72 % Restoration Plan 4.32 % 3.98 % 4.82 % Weighted-average actuarial assumptions used to determine benefit obligations for the plans were as follows: 2016 2015 RELS Pension Plan Discount rate 3.97 % 4.44 % Salary increase rate N/A N/A Expected return on plan assets 3.50 % 3.70 % SERPs Discount rate 4.00 % 4.20 % Salary increase rate N/A N/A Restoration Plan Discount rate 4.08 % 4.32 % The discount-rate assumption used for pension plan accounting reflects the yield available on high-quality, fixed-income debt securities that match the expected timing of the benefit obligation payments.

We make discretionary matching contributions to the Savings Plan based on participant contributions as well as discretionary contributions based on profitability. The expense within continuing operations for the years ended December 31, 2016 , 2015 and 2014 related to the Savings Plan were $10.8 million , $10.0 million and $5.7 million , respectively. The Savings Plan allows the participants to purchase shares of our common stock as one of the investment options, subject to certain limitations. The Savings Plan held 741,019 and 820,101 shares of our common stock, representing 0.9% of the total shares outstanding at December 31, 2016 and 2015 . We have a deferred compensation plan that allows participants to defer up to 80% of their salary, commissions and bonus. Participants allocate their deferrals among a variety of investment crediting options (“deemed investments”). Deemed investments mean that the participant has no ownership interest in the funds they select; the funds are only used to measure the gains or losses that will be attributed to their deferral account over time. Participants can elect to have their deferral balance paid out in a future year while they are still employed or after their employment ends. The participants’ deferrals and any earnings on those deferrals are our general unsecured obligation. We informally fund the deferred compensation plan through a tax-advantaged investment known as variable universal life insurance. Deferred compensation plan assets are held as an asset within a special trust. The value of the assets underlying our deferred compensation plan was $28.0 million and $27.4 million as of December 31, 2016 and 2015 , respectively, and is included in other assets in the accompanying consolidated balance sheets. The unfunded liability for our deferred compensation plan was $34.5 million and $32.2 million as of December 31, 2016 and 2015 , respectively, and is included in other liabilities in the accompanying consolidated balance sheets.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable. The market approach is applied for recurring fair value measurements and endeavors to utilize the best available information. Accordingly, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Fair value balances are classified based on the observability of those inputs. A fair value hierarchy prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). Level 2 measurements utilize observable inputs in markets other than active markets. In estimating the fair value of the financial instruments presented, we used the following methods and assumptions: Cash and cash equivalents For cash and cash equivalents, the carrying value is a reasonable estimate of fair value due to the short-term nature of the instruments. Restricted cash Restricted cash is comprised of certificates of deposit that are pledged for various letters of credit secured by us and escrow accounts due to acquisitions and divestitures. We deem the carrying value to be a reasonable estimate of fair value due to the nature of these instruments. Marketable securities Equity and debt securities are classified as available-for-sale securities and are valued using quoted prices in active markets. Contingent consideration The fair value of the contingent consideration was estimated using the Monte-Carlo simulation method, which relies on significant assumption and estimates including discount rates and future market conditions, among others. Long-term debt The fair value of long-term debt was estimated based on the current rates available to us for similar debt of the same remaining maturities and consideration of our default and credit risk. Interest rate swap agreements The fair value of the interest rate swap agreements \were estimated based on market value quotes received from the counter parties to the agreements. The fair values of our financial instruments as of December 31, 2016 are presented in the following table: Fair Value Measurements Using (in thousands) Level 1 Level 2 Level 3 Fair Value Financial Assets: Cash and cash equivalents $ 72,031 $ — $ — $ 72,031 Restricted cash — 17,943 — 17,943 $ 72,031 $ 17,943 $ — $ 89,974 Financial Liabilities: Total debt $ — $ 1,622,811 $ — $ 1,622,811 Derivatives: Asset for interest rate swap agreements $ — $ 5,392 $ — $ 5,392 Liability for interest rate swap agreements $ — $ 2,283 $ — $ 2,283 The fair values of our financial instruments as of December 31, 2015 are presented in the following table: Fair Value Measurements Using (in thousands) Level 1 Level 2 Level 3 Fair Value Financial Assets: Cash and cash equivalents $ 99,090 $ — $ — $ 99,090 Restricted cash — 10,926 — 10,926 Equity securities 22,709 — — 22,709 $ 121,799 $ 10,926 $ — $ 132,725 Financial Liabilities: Total debt $ — $ 1,315,473 $ — $ 1,315,473 Derivatives: Liability for interest rate swap agreements $ — $ 4,370 $ — $ 4,370 The following non-financial instruments were measured at fair value, on a nonrecurring basis, as of and for the year ended December 31, 2016 : Fair Value Measurements Using (in thousands) Remaining Fair Value Level 1 Level 2 Level 3 Impairment Losses Property and equipment, net $ — $ — $ — $ — $ 2,005 Capitalized data and database costs, net — — — — 882 Investment in affiliates, net 5,662 — — 5,662 23,431 $ 5,662 $ — $ — $ 5,662 $ 26,318 The following non-financial instruments were measured at fair value, on a nonrecurring basis, as of and for the year ended December 31, 2015 : Fair Value Measurements Using (in thousands) Remaining Fair Value Level 1 Level 2 Level 3 Impairment Losses Property and equipment, net $ — $ — $ — $ — $ 3,770 The following non-financial instruments were measured at fair value, on a nonrecurring basis, as of and for the year ended December 31, 2014 : Fair Value Measurements Using (in thousands) Remaining Fair Value Level 1 Level 2 Level 3 Impairment Losses Property and equipment, net — — — — 1,070 Goodwill, net — — — — 3,900 Investment in affiliates, net — — — — 360 $ — $ — $ — $ — $ 5,330 We recorded non-cash impairment charges of $2.0 million , $3.8 million and $1.1 million for the years ended December 31, 2016, 2015 and 2014 , respectively, in our property and equipment, net primarily related to internally developed software. Further, we recorded a non-cash impairment charge of $0.9 million for the year ended December 31, 2016 , in our capitalized data and database costs, net primarily related to a database that has become obsolete. Further, we recorded non-cash impairment charges of $3.9 million for the year ended December 31, 2014 , in our goodwill, net related to our technology solutions, solutions express and outsourcing services businesses. See Note 6 - Goodwill, Net for further discussion. Impairment losses from property and equipment, net and goodwill, net are recorded within depreciation and amortization in the accompanying consolidated statements of operations. We also recorded a non-cash impairment charge of $23.4 million and $0.4 million for the year ended December 31, 2016 and December 31, 2014 , respectively, in our investment in affiliates, net due to other-than-temporary losses in value from the absence of an ability to recover the carrying amount of the investments. In April 2016, we completed the acquisition of FNC for $400.0 million in cash paid at closing, subject to certain closing adjustments, and up to $75.0 million to be paid in cash in 2018, contingent upon the achievement of certain revenue targets in fiscal 2017. See Note 16 - Acquisitions for further discussion. We fair-valued the contingent payment using the Monte-Carlo simulation model and initially recorded $8.0 million as contingent consideration. The contingent payment is fair-valued quarterly and changes are recorded within gain on investments and other, net in our consolidated statements of operations. As of December 31, 2016 , we reversed the remaining balance on the contingent payment and recorded an $8.0 million gain for the year ended December 31, 2016 .

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation	Share-Based Compensation We currently issue equity awards under the Amended and Restated CoreLogic, Inc. 2011 Performance Incentive Plan, as amended, which was initially approved by our stockholders at our Annual Meeting, held on May 19, 2011 with an amendment and restatement approved by our stockholders at our Annual Meeting held on July 29, 2014, and a subsequent technical amendment by the Board in December 2016 ( the "Plan"). The Plan includes the ability to grant RSUs, PBRSUs and stock options. Prior to the approval of the Plan, we issued share-based awards under the CoreLogic, Inc. 2006 Incentive Plan. The Plan provides for up to 21,909,000 shares of the Company's common stock to be available for award grants. We have primarily utilized RSUs, PBRSUs and stock options as our share-based compensation instruments for employees and directors. The fair value of any share-based compensation instrument grant is based on the market value of our shares on the date of grant and is recognized as compensation expense over its vesting period. Restricted Stock Units For the years ended December 31, 2016 , 2015 and 2014 , we awarded 967,826 , 965,978 and 807,890 RSUs, respectively, with an estimated fair value of $33.7 million , $34.1 million and $24.7 million , respectively. The RSU awards will vest ratably over 3 years. RSU activity for the year ended December 31, 2016 is as follows: (in thousands, except weighted average fair value prices) Number of Shares Weighted Average Grant-Date Fair Value Unvested RSUs outstanding at December 31, 2015 1,537 $ 32.92 RSUs granted 968 $ 34.78 RSUs vested (835 ) $ 32.60 RSUs forfeited (115 ) $ 34.38 Unvested RSUs outstanding at December 31, 2016 1,555 $ 34.14 As of December 31, 2016 , there was $30.1 million of total unrecognized compensation cost related to unvested RSUs that is expected to be recognized over a weighted-average period of 1.9 years. The fair value of RSUs is based on the market value of the Company’s shares on the date of grant. Performance-Based Restricted Stock Units For the years ended December 31, 2016 , 2015 and 2014 , we awarded 285,475 , 231,624 and 367,558 PBRSUs, respectively, with an estimated fair value of $10.1 million , $7.9 million and $11.6 million , respectively. These awards could be subject to service-based, performance-based and market-based vesting. The performance period for the PBRSUs awarded during 2016 is from January 1, 2016 to December 31, 2018 and the performance metric is adjusted earnings per share and market-based conditions. Subject to satisfaction of the performance criteria, the 2016 awards will vest on December 31, 2018. The performance period for the PBRSUs awarded during 2015 is from January 1, 2015 to December 31, 2017 and the performance metric is adjusted earnings per share and market-based conditions. Subject to satisfaction of the performance criteria, the 2015 awards will vest on December 31, 2017. The performance period for the PBRSUs awarded during 2014 was from January 1, 2014 to December 31, 2016 and the performance metric was adjusted earnings per share and market based conditions. Based on achievement of the performance criteria, the 2014 awards were earned at 124% . The fair values of the 2016 , 2015 , and 2014 awards were estimated using Monte-Carlo simulation with the following weighted-average assumptions: 2016 2015 2014 Expected dividend yield — % — % — % Risk-free interest rate (1) 0.99 % 0.93 % 0.74 % Expected volatility (2) 25.12 % 24.01 % 27.88 % Average total shareholder return (2) (1.23 )% 8.37 % (0.90 )% (1) The risk-free interest rate for the periods within the contractual term of the PBRSUs is based on the U.S. Treasury yield curve in effect at the time of the grant. (2) The expected volatility and average total shareholder return is a measure of the amount by which a stock price has fluctuated or is expected to fluctuate based primarily on our and our peers' historical data. PBRSU activity for the year ended December 31, 2016 is as follows: (in thousands, except weighted average fair value prices) Number of Shares Weighted Average Grant-Date Fair Value Unvested PBRSUs outstanding at December 31, 2015 659 $ 29.15 PBRSUs granted 285 $ 35.39 PBRSUs vested (94 ) $ 26.49 PBRSUs forfeited (112 ) $ 22.37 Unvested PBRSUs outstanding at December 31, 2016 738 $ 34.13 As of December 31, 2016 , there was $14.1 million of total unrecognized compensation cost related to unvested PBRSUs that is expected to be recognized over a weighted-average period of 1.6 years. The fair value of PBRSUs is based on the market value of the Company’s shares on the date of grant. Stock Options In 2014 , we issued stock options as incentive compensation for certain key employees. The exercise price of each stock option is the closing market price of our common stock on the date of grant. The 2014 options vest in 3 equal annual installments on the first, second and third anniversaries of grant and expire 10 years after the grant date. The fair values of these stock options were estimated using a Black-Scholes model with the following weighted-average assumptions: 2014 Expected dividend yield — % Risk-free interest rate (1) 1.74 % Expected volatility (2) 37.92 % Expected life (3) 5.5 (1) The risk-free interest rate for the periods within the contractual term of the options is based on the U.S. Treasury yield curve in effect at the time of the grant. (2) The expected volatility is a measure of the amount by which a stock price has fluctuated or is expected to fluctuate based primarily on our and our peers' historical data. (3) The expected life is the period of time in years, on average, that participants are expected to hold their options before exercise based primarily on our historical data. For the year ended December 31, 2014 , we awarded 290,737 options, with an estimated fair value of $9.1 million . We did not issue any options for the December 31, 2015 and December 31, 2016 periods. Option activity for the year ended December 31, 2016 is as follows: (in thousands, except weighted average prices) Number of Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value Options outstanding at December 31, 2015 1,826 $ 21.33 Options granted — $ — Options exercised (321 ) $ 21.83 Options canceled (1 ) $ 30.52 Options outstanding at December 31, 2016 1,504 $ 21.22 4.6 $ 23,481 Options vested and expected to vest at December 31, 2016 1,503 $ 21.22 4.6 $ 23,478 Options exercisable at December 31, 2016 1,437 $ 20.73 4.4 $ 23,148 As of December 31, 2016 , there was $0.1 million of total unrecognized compensation cost related to unvested stock options that is expected to be recognized over a weighted-average period of 0.3 years. The intrinsic value of options exercised was $4.5 million , $9.0 million and $3.5 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. This intrinsic value represents the difference between the fair market value of the Company’s common stock on the date of exercise and the exercise price of each option. Employee Stock Purchase Plan The employee stock purchase plan allows eligible employees to purchase our common stock at 85.0% of the lesser of the closing price on the first day or the last day of each quarter. Our employee stock purchase plan was approved by our stockholders at our 2012 annual meeting of stockholders and the first offering period commenced in October 2012. We recognized an expense for the amount equal to the estimated fair value of the discount during the last offering period. The following table sets forth the share-based compensation expense recognized for the years ended December 31, 2016 , 2015 and 2014 : (in thousands) 2016 2015 2014 Restricted stock units $ 25,839 $ 24,591 $ 19,078 Performance-based restricted stock units 11,702 8,080 1,750 Stock options 1,017 1,923 3,730 Employee stock purchase plan 1,291 1,192 1,030 $ 39,849 $ 35,786 $ 25,588 The above share-based compensation expense has $4.5 million , $4.0 million and $1.7 million included within cost of services for the years ended December 31, 2016 , 2015 and 2014 , respectively. It also includes $0.2 million of share-based compensation expense for the year ended December 31, 2014 reported within loss from discontinued operations, net of tax.

Commitments and Contingencies Disclosure [Abstract]
Litigation and Regulatory Contingencies	Litigation and Regulatory Contingencies We have been named in various lawsuits and we may from time to time be subject to audit or investigation by governmental agencies. Currently, governmental agencies are auditing or investigating certain of our operations. With respect to matters where we have determined that a loss is both probable and reasonably estimable, we have recorded a liability representing our best estimate of the financial exposure based on known facts. While the ultimate disposition of each such audit, investigation or lawsuit is not yet determinable, we do not believe that the ultimate resolution of these matters, either individually or in the aggregate, will have a material adverse effect on our financial condition, results of operations or cash flows. In addition, we do not believe there is a reasonable possibility that a material loss exceeding amounts already accrued may be incurred. The ability to predict the ultimate outcome of such matters involves judgments, estimates and inherent uncertainties. The actual outcome of such matters could differ materially from management’s estimates. We record expenses for legal fees as incurred. Separation Following the Separation, we are responsible for a portion of FAFC's contingent and other corporate liabilities. In the Separation and Distribution Agreement, we agreed with FAFC to share equally in the cost of resolution of a small number of corporate-level lawsuits, including certain consolidated securities litigation matters from which we have since been dropped. There were no liabilities incurred in connection with the consolidated securities matters. Responsibility to manage each case has been assigned to either FAFC or us, with the managing party required to update the other party regularly and consult with the other party prior to certain important decisions, such as settlement. The managing party will also have primary responsibility for determining the ultimate total liability, if any, related to the applicable case. We will record our share of any such liability when the responsible party determines a reserve is necessary. At December 31, 2016 , no reserves were considered necessary. In addition, the Separation and Distribution Agreement provides for cross-indemnities principally designed to place financial responsibility for the obligations and liabilities of our predecessor, FAC's financial services business, with FAFC, and financial responsibility for the obligations and liabilities of FAC's information solutions business with us. Specifically, each party will, and will cause its subsidiaries and affiliates to, indemnify, defend and hold harmless the other party, its respective affiliates and subsidiaries and each of its respective officers, directors, employees and agents for any losses arising out of or otherwise in connection with the liabilities each such party assumed or retained pursuant to the Separation and Distribution Agreement; and any breach by such party of the Separation and Distribution Agreement.

Business Combinations [Abstract]
Acquisitions	Acquisitions In April 2016, we completed the acquisition of FNC for up to $475.0 million , with $400.0 million in cash paid at closing, subject to certain closing adjustments, and up to $75.0 million to be paid in cash in 2018, contingent upon the achievement of certain revenue targets in fiscal 2017. We fair-valued the contingent payment using the Monte-Carlo simulation model and initially recorded $8.0 million as contingent consideration. The contingent payment is fair-valued quarterly and changes are recorded within gain on investments and other, net in our consolidated statements of operations. See Note 12 - Fair Value of Financial Instruments for further discussion. FNC is a leading provider of real estate collateral information technology and solutions that automates property appraisal ordering, tracking, documentation and review for lender compliance with government regulations and is included as a component of our PI reporting segment. The acquisition expands our property valuation capabilities. The purchase price was allocated to the assets acquired and liabilities assumed using a variety of valuation techniques including discounted cash flow analysis, which included significant unobservable inputs. The purchase price allocation is subject to change based on our final determination of fair value in connection with intangible assets and working capital matters. We preliminarily recorded a deferred tax liability of $89.7 million , property and equipment of $79.8 million with an estimated average life of 12 years , customer lists of $141.8 million with an estimated average life of 16 years , trade names of $15.9 million with an estimated average life of 19 years , non-compete agreements of $18.8 million with an estimated average life of 5 years , other intangibles of $2.9 million with an estimated average life of 10 years and goodwill of $225.7 million . For the year ended December 31, 2016 , goodwill was increased by approximately $14.2 million from the initial amount recorded in the second quarter of 2016, as a result of a change in purchase price allocation for certain working capital and tax adjustments. This business combination did not have a material impact on our consolidated statements of operations. In January 2016, we acquired the remaining 40% interest in PIQ for NZD $27.8 million , or $19.0 million , and settled the mandatorily redeemable noncontrolling interest. PIQ is included as a component of our PI reporting segment. In December 2015, we completed the acquisition of the remaining 49.9% interest in RELS for approximately $65.0 million and recorded an investment gain of approximately $34.3 million due to the step-up in fair value on the previously held 50.1% interest, which is included in gain on investment and other, net in the accompanying consolidated statements of operations. RELS is included as a component of our PI reporting segment. The acquisition of RELS expands our real estate asset valuation and appraisal solutions in connection with loan originations. The purchase price was allocated to the assets acquired and liabilities assumed using a variety of valuation techniques including discounted cash flow analysis, which included significant unobservable inputs. We recorded property and equipment of $27.0 million with an estimated average life of 10 years , customer lists of $48.4 million with an estimated average life of 10 years , other intangibles of $5.0 million with an estimated useful life of 10 years and goodwill of $23.1 million , of which $11.5 million is deductible for tax purposes. The business combination did not have a material impact on our consolidated statements of operations. In October 2015, we completed the acquisition of Cordell for AUD $70.0 million , or $49.1 million , subject to working capital adjustments, which is included as a component of our PI reporting segment. The acquisition of Cordell further expands our property information capabilities in Australia. The purchase price was allocated to the assets acquired and liabilities assumed using a variety of valuation techniques including discounted cash flow analysis, which included significant unobservable inputs. We recorded property and equipment of $14.3 million with an estimated average life of 10 years , customer lists of $5.5 million with an estimated average life of 8 years , trade names of $0.6 million with an estimated useful life of 4 years and goodwill of $31.9 million , which is fully deductible for tax purposes. The business combination did not have a material impact on our consolidated statements of operations. In September 2015, we completed the acquisition of LandSafe for $ 122.0 million , subject to working capital adjustments, which is included as a component of our PI reporting segment. The acquisition builds on our longstanding strategic relationship with a key client and continues to expand our property valuation capabilities. The purchase price was allocated to the assets acquired and liabilities assumed using a variety of valuation techniques including discounted cash flow analysis, which included significant unobservable inputs. We recorded customer lists of $53.4 million with an estimated average life of 10 years , other intangibles of $4.3 million with an estimated useful life of 10 years and goodwill of $64.6 million , which is fully deductible for tax purposes. The business combination did not have a material impact on our consolidated statements of operations. In November 2014, we completed our acquisition of Bank of America's mortgage-related credit reporting operation for approximately $19.6 million , which is included as a component of our RMW reporting segment. The purchase price was allocated to the assets acquired and liabilities assumed using a variety of valuation techniques including discounted cash flow analysis, which included significant unobservable inputs. We recorded property and equipment of $4.3 million with an estimated average life of 3 years, client lists of $6.1 million with an estimated average life of 10 years and goodwill of $9.2 million , which is fully deductible for tax purposes. The business combination did not have a material impact on our consolidated statements of operations.

In addition, we acquired the assets of the credit, flood services and automated valuation model operations of DataQuick Lending Solutions and certain intellectual property assets of Decision Insight Information Group S.à r.l. The total consideration paid in connection with the MSB/DataQuick acquisition was approximately $652.5 million in cash, which was funded through borrowings. The acquisition of MSB/DataQuick significantly expands our footprint in property and casualty insurance and adds scale to our existing property data and analytics business, which is a contributing factor to the recording of goodwill. The operations of MSB's and DataQuick's data licensing and analytics units are reported within our PI segment and DataQuick's flood zone determination and credit servicing operations are reported within our RMW segment. The purchase price was allocated to the assets acquired and liabilities assumed using a variety of valuation techniques including discounted cash flow analysis, which included significant unobservable inputs. Any excess of the purchase price over the fair value of identified assets acquired and liabilities assumed is recognized as goodwill. The allocation of the purchase price is as follows: (in thousands) Cash and cash equivalents $ 36 Accounts receivable 9,227 Prepaid expenses and other current assets 2,190 Deferred income tax assets, current 6,658 Property and equipment 177,311 Goodwill (1) 307,773 Other intangible assets 129,400 Deferred income tax, net of current 29,760 Investment in affiliates 18,300 Total assets acquired $ 680,655 Accounts payable and accrued expenses 3,911 Income taxes payable 31 Deferred revenue, current 22,371 Deferred revenue, net of current 1,823 Net assets acquired $ 652,519 (1) Goodwill of $307.8 million includes $167.8 million of deductible basis for tax purposes. We reported revenues and net loss of approximately $67.5 million and $5.8 million , respectively, from the MSB/DataQuick acquisition from the acquisition date of March 25, 2014 through December 31, 2014 . The net loss includes $18.6 million of depreciation and amortization from acquired property and equipment and other intangible assets.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations On September 30, 2014, we completed the sale of our collateral solutions and field services businesses, which were previously included in the former reporting segment Asset Management and Processing Solutions ("AMPS"), for total consideration of $29.1 million , subject to working capital adjustments. In September 2012, we completed the wind down of our consumer services business and our then-owned appraisal management company business which were included in our PI and RMW segments, respectively. In September 2011, we closed our marketing services business which was included in our PI segment. In December 2010, we completed the sale of our Employer and Litigation Services businesses ("ELI"). For the year ended December 31, 2016, we recorded a $1.9 million loss on the sale of discontinued operations, net of tax, primarily due to transaction payments under an amendment to the sale agreement of collateral solutions and field services businesses. For the year ended December 31, 2014, we recorded a $0.1 million gain on the sale of discontinued operations, net of tax, primarily related to $1.5 million of earn-out payments, net of tax, from previously disposed discontinued operations, partially offset by an after-tax loss of $1.4 million related to the sale of our collateral solutions and field services businesses. In connection with previous divestitures, we retain the prospect of contingent liabilities for indemnification obligations or breaches of representations or warranties. With respect to one such divestiture, an unfavorable jury verdict against a discontinued operating unit has recently been reduced to judgment that, if upheld on appeal, could result in the reasonable possibility of indemnification exposure up to $25.0 million , including interest. We do not consider this outcome to be probable and intend to vigorously assert our contractual and other rights, including to pursue an appeal to eliminate or substantially reduce any potential post-divestiture contingency. The judgment is currently on appeal. Any actual liability that comes to fruition would be reflected in our results from discontinued operations. Each of these businesses is reflected in our accompanying consolidated financial statements as discontinued operations and the results of these businesses in the prior years have been recast to conform to the 2016 presentation. Summarized below are certain assets and liabilities classified as discontinued operations as of December 31, 2016 and 2015 : (in thousands) As of December 31, 2016 PI RMW ELI AMPS Total Deferred income tax asset, current $ 325 $ (231 ) $ — $ 568 $ 662 Accounts payable, accrued expenses and other liabilities $ 202 $ 167 $ 624 $ 2,130 $ 3,123 As of December 31, 2015 Deferred income tax and other current assets $ 326 $ (217 ) $ — $ 572 $ 681 Accounts payable, accrued expenses and other liabilities $ 250 $ 319 $ — $ 1,958 $ 2,527 Summarized below are the components of our loss from discontinued operations, net of tax for the years ended December 31, 2016 , 2015 and 2014 : (in thousands) For the Year Ended December 31, 2016 PI RMW ELI AMPS Total Operating revenue $ — $ — $ — $ — $ — (Loss)/income from discontinued operations before income taxes (37 ) 142 (1,600 ) (890 ) (2,385 ) (Benefit)/Provision for income taxes (14 ) 50 (612 ) (343 ) (919 ) (Loss)/income from discontinued operations, net of tax $ (23 ) $ 92 $ (988 ) $ (547 ) $ (1,466 ) For the Year Ended December 31, 2015 Operating revenue $ — $ — $ — $ — $ — Loss from discontinued operations before income taxes (650 ) (20 ) — (230 ) (900 ) Benefit for income taxes (204 ) (52 ) — (88 ) (344 ) (Loss)/income from discontinued operations, net of tax $ (446 ) $ 32 $ — $ (142 ) $ (556 ) For the Year Ended December 31, 2014 Operating revenue $ — $ — $ — $ 94,039 $ 94,039 (Loss)/income from discontinued operations, net of tax (717 ) (30,739 ) — 7,188 (24,268 ) (Benefit)/provision for income taxes (350 ) (11,785 ) — 4,520 (7,615 ) (Loss)/income from discontinued operations, net of tax $ (367 ) $ (18,954 ) $ — $ 2,668 $ (16,653 )

Significant Accounting Polici28

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include our accounts and all controlled subsidiaries. All significant intercompany transactions and balances have been eliminated. Equity investments in which we exercise significant influence, do not control, and are not the primary beneficiary, are accounted for using the equity method. Investments in which we do not exercise significant influence over the investee are accounted for under the cost method.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Client Concentration We generate the majority of our revenues from clients with operations in the U.S. residential real estate, mortgage origination and mortgage servicing markets. Approximately 43.0% , 33.5% , and 29.8% of our operating revenues for the year ended December 31, 2016, 2015 and 2014 , respectively, were generated from our ten largest clients who consist of the largest U.S. mortgage originators and servicers. Two of our clients accounted for 14.0% and 11.5% of our operating revenues for the year ended December 31, 2016 . Both our PI and RMW segments reported revenue from these two customers. No client accounted for 10.0% or more of our operating revenues for the years ended December 31, 2015 or December 31, 2014
Schedule of Error Corrections and Prior Period Adjustments [Table Text Block]	Out-of-Period Adjustment During the fourth quarter of 2016, we identified an error which overstated our provision for income taxes by $4.4 million and understated our provision for income taxes by $1.3 million , both reflected within continuing operations, for the years ended December 31, 2015 and 2014, respectively. We recorded a net out-of-period adjustment of $3.1 million to correct the error in the quarter ended December 31, 2016, which increased basic and diluted net income per share by $0.03 . We assessed the materiality of this error and concluded the error was not material to the results of operations or financial condition for the current or prior annual or interim periods presented. See further discussion in Note 9 – Income Taxes. During the first quarter of 2015, we identified an error which overstated our interest expense by $5.2 million ( $3.1 million , net of tax), reflected within continuing operations, for the year ended December 31, 2014. We recorded an out-of-period adjustment to correct the error in the quarter ended March 31, 2015, which increased basic and diluted net income per share by $0.03 . We assessed the materiality of this error and concluded the error was not material to the results of operations or financial condition for the current or prior annual or interim periods presented.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with generally accepted accounting policies ("GAAP") requires management to make estimates and assumptions that affect the financial statements. Actual results could differ from the estimates and assumptions used.
Cash Equivalents	Cash Equivalents We consider cash equivalents to be all short-term investments that have an initial maturity of 90 days as of the date of purchase or less and are not restricted.
Accounts Receivable	Accounts Receivable Accounts receivable are generally due from mortgage originators and servicers, financial institutions, insurers, government and government-sponsored enterprises located throughout the United States and abroad. Credit is extended based on an evaluation of the client’s financial condition, and generally, collateral is not required. The allowance for doubtful accounts for all probable uncollectible receivables is based on a combination of historical data, cash payment trends, specific client issues, write-off trends, general economic conditions and other factors. These factors are continuously monitored by management to arrive at the estimate for the amount of accounts receivable that may be ultimately uncollectible. In circumstances where a specific client is unable to meet its financial obligations, we record a specific allowance for doubtful accounts against amounts due to reduce the net recognized receivable to the amount we reasonably believe will be collected.
Marketable Securities	Marketable Securities Debt securities are carried at fair value and consist primarily of investments in obligations of various corporations and mortgage-backed securities. Equity securities are carried at fair value and consist primarily of investments in marketable common and preferred stock. We classify our publicly traded debt and equity securities as available-for-sale and carry them at fair value with unrealized gains or losses classified as a component of accumulated other comprehensive loss. In October 2016, we liquidated our debt security at par value and reversed $0.5 million of unrealized gain previously recorded in other comprehensive loss. We realized no gain or loss for this transaction. As of December 31, 2015 , our marketable securities consisted of investments in preferred stock totaling $22.7 million .
Property and Equipment	Property and Equipment Property and equipment is recorded at cost and includes computer software acquired or developed for internal use and for use with our products. Software development costs include certain payroll-related costs of employees directly associated with developing software and payments to third parties for completed or developing software. We begin capitalizing qualifying software development costs on a project when the preliminary project stage is completed and management has authorized further funding for completion. Capitalization ends once a project is substantially complete and the software is ready for its intended use. Costs incurred in the planning and post-implementation phases of software developing are expensed as incurred. Depreciation on buildings and on furniture and equipment is computed using the straight-line method over estimated useful lives of 25 to 40 , and 3 to 10 years, respectively. Capitalized software costs are amortized using the straight-line method over estimated useful lives of 3 to 10 years. Leasehold improvements are amortized over the lesser of the estimated useful life or the lease term.
Capitalized Data and Database Developement Costs, Net	Capitalized Data and Database Development Costs, Net Capitalized data and database development costs represent our cost to acquire or develop the proprietary databases of information for client use. The costs are capitalized from the time the third party data is acquired until the information is ready for use, assuming both the preliminary project stage is complete and management has authorized funding for the completion of the data project. Property and eviction data costs are amortized using the straight-line method over estimated useful lives of 5 to 20 years. The carrying value for the flood data zone certification was $55.4 million as of December 31, 2016 and 2015 . Because properly maintained flood zone databases have indefinite lives and do not diminish in value with the passage of time, no provision has been made for depreciation or amortization. We periodically analyze our assets for impairment. This analysis includes, but is not limited to, the effects of obsolescence, duplication, demand and other economic factors. See further discussion in Note 4 – Capitalized Data and Database Development Costs, Net.
Restricted Cash	Restricted Cash Restricted cash is comprised of certificates of deposit that are pledged for various letters of credit secured by us and escrow accounts due to acquisitions and divestitures. We deem the carrying value to be a reasonable estimate of fair value due to the nature of these instruments.
Purchase Accounting	Purchase Accounting The purchase method of accounting requires companies to assign values to assets and liabilities acquired based upon their fair values at the acquisition date. In most instances, there are not readily defined or listed market prices for individual assets and liabilities acquired in connection with a business, including intangible assets. The determination of fair value for assets and liabilities in many instances requires a high degree of estimation. The valuation of intangible assets, in particular, is very subjective. We generally obtain third-party valuations to assist us in estimating fair values. The use of different valuation techniques and assumptions could change the amounts and useful lives assigned to the assets and liabilities acquired and related amortization expense.
Goodwill	Goodwill We perform an annual impairment test for goodwill and other indefinite-lived intangible assets for each reporting unit every fourth quarter, or on an interim basis if an indicator of impairment is present. In assessing the overall carrying value of our goodwill and other intangibles, we could first assess qualitative factors to determine whether the fair value of a reporting unit is less than its carrying amount. Examples of such events or circumstances include the following: cost factors, financial performance, legal and regulatory factors, entity specific events, industry and market factors, macroeconomic conditions and other considerations. If we determine that it is more likely than not that the fair value of a reporting unit is less than its carrying value, then quantitative impairment testing is performed. We could also elect to perform a quantitative impairment test without first assessing qualitative factors. In analyzing goodwill for the quantitative impairment test, we use a combination of the income and market approach. If the fair value of the reporting unit exceeds its book value, then goodwill is not considered impaired and no additional analysis is required. However, if the book value is greater than the fair value, a second step must be completed to determine if the implied fair value of the goodwill exceeds its book value. This involves calculating an implied fair value of goodwill for each reporting unit that indicated impairment. If the carrying value of goodwill assigned to a reporting unit exceeds its implied fair value, an impairment loss is recorded for the excess. The valuation of goodwill requires assumptions and estimates of many critical factors including revenue growth, cash flows, market multiples and discount rates. In assessing the fair value of indefinite lived intangibles, we compare the fair value of the asset to its carrying value to determine if there is an impairment. If the fair value of the asset is less than its carrying value, an impairment loss is recorded. See further discussion in Note 6 – Goodwill, Net.
Other Intangible Assets	Other Intangible Assets Our intangible assets consist of covenants not to compete, client lists and trade names. Each of these intangible assets is amortized on a straight-line basis over its useful life ranging from 2 to 20 years and is subject to impairment tests if an indicator of impairment is present.
Long-Lived Assets	Long-Lived Assets Long-lived assets held and used include property and equipment, capitalized software and other intangible assets. Management uses estimated future cash flows (undiscounted and excluding interest) to measure the recoverability of long-lived assets held and used, at the asset group level, whenever events or changes in circumstances indicate that the carrying value of an asset may not be fully recoverable. If the undiscounted cash flow analysis indicates a long-lived asset is not recoverable, the impairment loss recorded is the excess of the carrying amount of the asset over its fair value. In addition, we carry long-lived assets held for sale at the lower of cost or market as of the date that certain criteria have been met.
Equity Method Investments, Policy [Policy Text Block]	Investment in Affiliates Investments in affiliates are accounted for under the equity method of accounting when we are deemed to have significant influence over the affiliate but do not control or have a majority voting interest in the affiliate. Investments are carried at the cost of acquisition, including subsequent capital contributions and loans from us, plus our equity in undistributed earnings or losses since inception of the investment. The carrying value of investments in affiliates is written down, or impaired, to fair value when a decline in value is considered to be other-than-temporary. In making the determination as to whether an individual investment in an affiliate is impaired, we assesses the current and expected financial condition of each relevant entity, including, but not limited to, the entity’s anticipated ability to generate sufficient cash flows and the market conditions in the industry in which the entity operates. We recognized impairment losses of $23.4 million and $0.4 million on investment in affiliates for the years ended December 31, 2016 and 2014 , respectively. There were no losses recognized in 2015 .
Mandatorily Redeemable Noncontrolling Interest [Policy Text Block]	Mandatorily Redeemable Noncontrolling Interest Mandatorily redeemable noncontrolling interests for which there is a contractual requirement to purchase the interest are included as a liability of NZD $27.8 million , or $19.0 million , in our accompanying condensed consolidated balance sheet as of December 31, 2015 . In January 2016, we acquired the remaining 40.0% interest in New Zealand-based Property IQ Ltd. ("PIQ") and settled the mandatorily redeemable noncontrolling interest. As a result, there was no mandatorily redeemable noncontrolling interest balance as of December 31, 2016 . For the years ended December 31, 2015 and 2014 , we recorded $1.2 million and $1.3 million , respectively, of net income in connection with the redeemable noncontrolling interest.
Revenue Recognition	Revenue Recognition We derive our revenues principally from U.S. mortgage originators and servicers with good creditworthiness. Our product and service deliverables are generally comprised of data or other related services. Our revenue arrangements with our clients generally include a work order or written agreement specifying the data products or services to be delivered and related terms of sale including payment amounts and terms. The primary revenue recognition-related judgments we exercise are to determine when all of the following criteria have been met: (i) persuasive evidence of an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) our price to the buyer is fixed or determinable; and (iv) collectability is reasonably assured. For products or services where delivery occurs at a point in time, we recognize revenue upon delivery. These products or services include sales of tenancy data and analytics, credit solutions for mortgage and automotive industries, under-banked credit services, flood data and services and claims management. For products or services where delivery occurs over time, we recognize revenue ratably on a subscription basis over the contractual service period once initial delivery has occurred. Generally these service periods range from one to three years. Products or services recognized on a license or subscription basis include information and analytic products, property risk and replacement cost, flood database licenses, realtors solutions and lending solutions. For certain of our products or services, clients may also pay us upfront set-up fees, which we defer and recognize into revenue over the longer of the contractual term or expected client relationship period. Property tax processing revenues are comprised of periodic loan fees and life-of-loan fees. For periodic fee arrangements, we generate monthly fees at a contracted rate for as long as we service the loan. Loans serviced with a one-time, life-of-loan fee are billed once the loan is boarded to our tax servicing system in accordance with a client tax servicing agreement. Life-of-loan fees are then deferred and recognized ratably over the expected service period. The rates applied to recognize revenues assume a 10 -year expected life and are adjusted to reflect prepayments. We review the tax service contract portfolio monthly to determine if there have been material changes in the expected lives, deferred on-boarding costs, expected service period and/or changes in the number and/or timing of prepayments. Accordingly, we may adjust the rates to reflect current trends.
Cost of Services	Cost of Services Cost of services represents direct costs incurred in the creation and delivery of our products and services. Cost of services consists primarily of data acquisition costs, royalty fees, hardware and software expense associated with transaction processing systems, telecommunication and computer network expense and occupancy costs associated with facilities where these functions are performed by employees. Cost of services also includes client service costs, which include personnel costs to collect, maintain and update our proprietary databases, to develop and maintain software application platforms and to provide consumer and client call center support.
Selling, General and Administrative Expenses	Selling, General and Administrative Expenses Selling, general and administrative expenses consist primarily of personnel-related costs, selling costs, corporate costs, fees for professional and consulting services, advertising costs, uncollectible accounts and other costs of administration such as marketing, human resources, finance, legal and administrative roles.
Income Taxes	Income Taxes We account for income taxes under the asset and liability method, whereby we recognize deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases as well as expected benefits of utilizing net operating loss and credit carryforwards. We measure deferred tax assets and liabilities using enacted tax rates we expect to apply in the years in which we expect to recover or settle those temporary differences. We recognize in income the effect of a change in tax rates on deferred tax assets and liabilities in the period that includes the enactment date. We recognize the effect of income tax positions only if sustaining those positions is more likely than not. We reflect changes in recognition or measurement of uncertain tax positions in the period in which a change in judgment occurs. We recognize interest and penalties, if any, related to uncertain tax positions within income tax expense. Accrued interest and penalties are included within the related tax liability line in the accompanying consolidated balance sheet. We evaluate the need to establish a valuation allowance based upon expected levels of taxable income, future reversals of existing temporary differences, tax planning strategies and recent financial operations. We establish a valuation allowance to reduce deferred tax assets to the extent it is more-likely-than-not that some or all of the deferred tax assets will not be realized.
Comprehensive Income (Loss)	Comprehensive Income Comprehensive income includes all changes in equity except those resulting from investments by owners and distributions to owners. Specifically, foreign currency translation adjustments, amounts related to supplemental benefit plans, unrealized gains and losses on interest rate swap transactions and unrealized gains and losses on investment are recorded in other comprehensive loss. The following table shows the components of accumulated other comprehensive loss, net of taxes as of December 31, 2016 and 2015 : 2016 2015 Cumulative foreign currency translation $ (118,071 ) $ (114,427 ) Cumulative supplemental benefit plans (6,267 ) (3,540 ) Net unrecognized losses on interest rate swap 1,920 (2,699 ) Net unrealized gains on marketable securities — 550 Accumulative other comprehensive loss $ (122,418 ) $ (120,116 )
Share-based Compensation	Share-based Compensation Currently, our primary means of providing stock-based compensation is granting restricted stock units (“RSUs”) and performance-based restricted stock units (“PBRSUs”). The fair value of any grant is based on the market value of our shares on the date of grant and is generally recognized as compensation expense over the vesting period. We measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The cost is recognized over the period during which an employee is required to provide services in exchange for the award. We utilize the Monte-Carlo simulation method to estimate the fair value for any PBRSUs granted and the Black-Scholes model to estimate the fair value of stock options. We apply the straight-line single option method of attributing the value of stock-based compensation expense. As stock-based compensation expense recognized in results of operations is based on awards ultimately expected to vest, stock-based compensation expense has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. We apply the long-form method for determining the pool of windfall tax benefits. In addition, we have an employee stock purchase plan that allows eligible employees to purchase common stock of the Company at 85.0% of the closing price on the first or last day of each quarter, whichever is lower (which was updated for 2014 from the closing price on the last day of each quarter). We recognize an expense in the amount equal to the estimated fair value of the discount. See Note 13 –Share-based Compensation Plans for additional information related to stock options and RSUs.
Foreign Currency	Foreign Currency The functional currencies of our foreign subsidiaries are their respective local currencies. The financial statements of the foreign subsidiaries are translated into U.S. dollars for consolidation as follows: (i) assets and liabilities at the exchange rate as of the balance sheet date, (ii) stockholders’ equity at the historical rates of exchange and (iii) income and expense amounts at average rates prevailing throughout the period. Translation adjustments resulting from the translation of the subsidiaries’ accounts are included in “Accumulated other comprehensive loss,” a separate component of stockholders’ equity. Gains and losses resulting from foreign currency transactions are included within “Selling, general and administrative expenses” and are not material to the results of operations.
Earnings (loss) Per Share	Earnings/(Loss) Per Share Basic earnings/(loss) per share is computed by dividing net income/(loss) available to our stockholders by the weighted-average number of common shares outstanding. The computation of diluted earnings per share is similar to the computation of basic earnings per share, except that the weighted-average number of common shares outstanding is increased to include the number of additional common shares that would have been outstanding if dilutive stock options had been exercised and RSUs and PBRSUs were vested. The dilutive effect of stock options and unvested RSUs and PBRSUs is computed using the treasury stock method, which assumes any proceeds that could be obtained upon the exercise of stock options and vesting of RSUs and PBRSUs would be used to purchase shares of common stock at the average market price for the period. The assumed proceeds include any purchase price the grantee pays, the hypothetical windfall tax benefit that we receive upon assumed exercise or vesting and the hypothetical average unrecognized compensation expense for the period. We calculate the assumed proceeds from excess tax benefits based on the “as-if” deferred tax assets calculated under stock-based compensation standards.
Escrow Administration Arrangements	Tax Escrow Disbursement Arrangements We administer tax escrow disbursements as a service to our clients in connection with our tax services business. These deposits are maintained in segregated accounts for the benefit of our clients. These deposits totaled $619.4 million and $340.3 million at December 31, 2016 and 2015 , respectively. Because these deposits are held on behalf of our clients, they are not our funds and, therefore, are not included in the accompanying consolidated balance sheets. These deposits generally remain in the accounts for a period of two to five business days. We record earnings credits from these investments to mitigate the cost of bank-related fees. Under our contracts with our clients, if we make a payment in error or fail to pay a taxing authority when a payment is due, we could be held liable to our clients for all or part of the financial loss they suffer as a result of our act or omission. We maintained claim reserves relating to incorrect disposition of assets of $22.2 million and $21.2 million as of December 31, 2016 and 2015 , respectively.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements In November 2016, the Financial Accounting Standards Board (“FASB”) issued guidance providing that restricted cash and restricted cash equivalents are to be included with cash and cash equivalents on the statement of cash flows. The guidance is effective in fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Earlier adoption is permitted but we do not anticipate electing early adoption. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In October 2016, the FASB issued guidance pursuant to which an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Two common examples of assets transferred intra-entity are intellectual property and property, plant, and equipment. The guidance is effective in fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Earlier adoption is permitted but we do not anticipate electing early adoption. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In October 2016, the FASB issued guidance related to the consolidation of a variable interest entity (“VIE”). Indirect interests held through related parties that are under common control with the single decision maker are no longer required to be considered the equivalent of direct interests in their entirety. Instead, a single decision maker is required to include those interests on a proportionate basis consistent with indirect interests held through other related parties. The guidance is effective in fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In August 2016, the FASB issued guidance on eight specific cash flow classification issues that were either unclear or where no specific guidance was provided. The specific issues include i) debt prepayment or debt extinguishment costs; ii) settlement of zero-coupon debt instruments; iii) contingent consideration payments made after a business combination; iv) proceeds from the settlement of insurance claims; v) proceeds from the settlement of company-owned life insurance; vi) distributions received from equity method investees; vii) beneficial interests in securitization transactions; and, viii) separately identifiable cash flows and application of the predominance principle. The guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years and earlier adoption is permitted. We have elected early adoption and the guidance did not have a material impact on our consolidated financial statements. In June 2016, the FASB issued guidance for accounting of credit losses affecting the impairment model for most financial assets and certain other instruments. Entities will be required to use a new forward-looking current expected credit loss model for trade and other receivables, held-to-maturity debt securities, loans and other instruments, which will generally lead to an earlier recognition of loss allowances. Entities will recognize expected losses on available-for-sale debt securities as allowances rather than a reduction in amortized cost of the security while the measurement process of this loss does not change. Disclosure requirements are expanded regarding an entity’s assumptions, models and methods of estimations of the allowance. The guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Earlier adoption is permitted but we do not anticipate electing early adoption. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In March 2016, the FASB issued guidance to simplify some provisions in stock compensation accounting. The accounting for income taxes requires all excess tax benefits and tax deficiencies to be recognized through income tax expense. The statement of cash flows presentation of excess tax benefits should be classified with other income tax cash flows as an operating activity. An entity may also make an entity-wide election to either continue estimating the number of awards that are expected to vest or account for forfeitures as they occur. The requirements to qualify for equity classification permits tax withholding up to the maximum statutory tax rates in the applicable jurisdictions. Lastly, payments of cash by an employer for tax-withholding purposes, when directly withholding shares, are classified as a financing activity on the statement of cash flows. The guidance is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Earlier adoption is permitted but we did not elect early adoption. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In March 2016, the FASB issued guidance on equity method accounting related to joint venture investments. The standard eliminates the requirement to retroactively adopt the equity method of accounting as a result of an increase in the level of ownership or degree of influence related to an investment. The guidance is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Earlier adoption is permitted but we did not elect early adoption. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In March 2016, the FASB issued guidance on derivatives and hedging. The standard clarifies the four-step decision sequence required for assessing whether contingent put and call options that can speed up the payment for a debt instrument’s principal are clearly and closely related to the debt to which they are attached. The standard also clarifies that, provided all other hedge accounting criteria continue to be met, a change in the counterparty to a derivative instrument does not in itself disqualify designation of the hedge. The guidance is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Earlier adoption is permitted but we did not elect early adoption. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In February 2016, the FASB issued guidance on lease accounting. The standard requires all leases in excess of 12-months to be recognized on the balance sheet as lease assets and lease liabilities. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee have not changed significantly from prior GAAP. For operating leases, a lessee is required to i) recognize a right-of-use asset and lease liability, initially measured at the present value of the lease payment, ii) recognize a single lease cost over the lease term generally on a straight-line basis, and iii) classify all cash payments within operating activities on the cash flow statement. The guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Earlier adoption is permitted but we do not anticipate electing early adoption. We are currently evaluating the impact of the adoption of this guidance on our consolidated financial statements. In January 2016, the FASB issued guidance on accounting for equity investments and financial liabilities. The standard does not apply to equity method investments or investments in consolidated subsidiaries. The update provides that equity investments with readily determinable values be measured at fair value and changes in the fair value flow through net income. These changes historically have run through other comprehensive income. Equity investments without readily determinable fair values have the option to be measured at fair value or at cost adjusted for changes in observable prices minus impairment. Changes in either method are also recognized in net income. The standard requires a qualitative assessment of impairment indicators at each reporting period. For financial liabilities, entities that elect the fair value option must recognize the change in fair value attributable to instrument-specific credit risk in other comprehensive loss rather than net income. Lastly, regarding deferred tax assets, the need for a valuation allowance on a deferred tax asset will need to be assessed related to available-for-sale debt securities. The guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Earlier adoption is permitted but we do not anticipate electing early adoption. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In November 2015, the FASB issued guidance which requires all deferred tax assets and liabilities, as well as any related valuation allowance, to be classified as non-current on the balance sheet. The guidance is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years and earlier adoption is permitted. As of March 31, 2016, we elected early adoption on a prospective basis and, as of December 31, 2016, we presented $1.5 million of deferred income tax assets, long term and $120.1 million of deferred income tax liabilities, long term in the accompanying consolidated balance sheet. In September 2015, the FASB issued updated guidance, which eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. Acquirers must recognize measurement-period adjustments during the period of resolution, including the effect on earnings of any amounts they would have recorded in previous periods if the accounting had been completed at the acquisition date. The updated guidance is effective for fiscal years beginning after December 15, 2015. Adoption of this guidance did not have a material impact on our consolidated financial statements. In April 2015, FASB issued guidance, which requires that debt issuance costs be presented in the balance sheet as a deduction from the carrying amount of the related liability, rather than as a deferred charge. The updated guidance is effective retrospectively for financial statements covering fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Adoption of this guidance did not have a material impact on our consolidated financial statements. In February 2015, the FASB issued guidance, which modifies the analysis regarding the evaluation of certain types of entities to be consolidated. Specifically, it (i) modifies the assessment of whether limited partnerships are VIEs, (ii) eliminates the presumption that a limited partnership should be consolidated by its general partner, (iii) removes certain conditions for the evaluation of whether a fee paid to a decision-maker constitutes a variable interest, and (iv) modifies the evaluation concerning the impact of related parties in the determination of the primary beneficiary of a VIE. The updated guidance is effective for annual reporting periods and interim periods within those annual periods beginning after December 15, 2015. Adoption of this guidance did not have a material impact on our consolidated financial statements. In January 2015, the FASB issued guidance, which completely eliminates all references to and guidance concerning the concept of an extraordinary item. The updated guidance is effective for annual reporting periods and interim periods within those annual periods beginning after December 15, 2015. Adoption of this guidance did not have a material impact on our consolidated financial statements. In August 2014, the FASB issued updated guidance related to determining whether substantial doubt exists about an entity's ability to continue as a going concern. The amendment provides guidance for determining whether conditions or events give rise to substantial doubt that an entity has the ability to continue as a going concern within one year following issuance of the financial statements and requires specific disclosures regarding the conditions or events leading to substantial doubt. The updated guidance is effective for annual reporting periods and interim periods within those annual periods ending after December 15, 2016. Earlier adoption is permitted but we did not elect early adoption. Adoption of this guidance did not have a material impact on our consolidated financial statements. In June 2014, the FASB issued updated guidance related to stock compensation. The amendment requires that a performance target that affects vesting and that could be achieved after the requisite period, be treated as a performance condition. The updated guidance is effective for annual reporting periods and interim periods within those annual periods beginning after December 15, 2015. Adoption of this guidance did not have a material impact on our consolidated financial statements. In May 2014, the FASB issued updated guidance on revenue recognition in order to i) remove inconsistencies in revenue requirements, ii) provide a better framework for addressing revenue issues, iii) improve comparability across entities, industries, etc., iv) provide more useful information through improved disclosures, and v) simplify the preparation of financial statements by reducing the number of requirements to which an entity must refer. Under the amendment, an entity should recognize revenue to depict the transfer of promised goods or services to clients in the amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also specifies the accounting treatment for the incremental costs of obtaining a contract, which would not have been incurred had the contract not been obtained. Further, an entity is required to disclose sufficient information to enable the user of the financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows from contracts with clients. The updated guidance provides two methods of adoption: i) retrospective application to each prior reporting period presented, or ii) recognition of the cumulative effect from the retrospective application at the date of initial application. As updated by FASB in August 2015, the guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Earlier adoption is permitted for annual reporting periods beginning after December 15, 2016 but we did not elect early adoption. We are analyzing the impact of the updated guidance on our substantial portfolio of contracts across our various revenue streams. Further, we are evaluating the impact to our systems, controls and processes required to support the new accounting and disclosure requirements. We are completing our qualitative assessment and have begun efforts to quantify the financial impact to our consolidated financial statements and conclude on system requirements. Once our evaluation is complete we will select the method of adoption and further disclose the quantitative impact of adopting the updated guidance.
