Income Tax Disclosure [Abstract]
Income Taxes	Note 7 – Income Taxes The Company’s effective income tax rates (income tax expense as a percentage of income before income taxes) were 33.8% and 32.9% for the three and six months ended June 30, 2017, respectively, and 33.3% and 32.3% for the three and six months ended June 30, 2016, respectively. The Company’s effective tax rates differ from the statutory federal rate of 35% primarily due to changes in state and foreign income taxes resulting from fluctuations in the Company’s noninsurance and foreign subsidiaries’ contributions to pretax income and changes in the ratio of permanent differences to income before income taxes. The Company’s effective tax rate for 2017 also reflects the adoption of new accounting guidance related to the accounting for share-based payment transactions, which requires, among other items, that all excess tax benefits and tax deficiencies associated with share-based payment transactions be recorded in income tax expense rather than in additional paid-in capital, as previously required. The impact to the Company of adopting this guidance was a reduction in income tax expense of $0.3 million and $2.7 million for the three and six months ended June 30, 2017, respectively. See Note 1 Basis of Condensed Consolidated Financial Statements for further discussion of the new guidance. The Company’s effective tax rate for 2016 reflects the resolution of certain tax authority examinations and tax credits claimed in 2016 and in prior years. In connection with the Company’s June 2010 spin-off from its prior parent, which subsequently assumed the name CoreLogic, Inc. (“CoreLogic”), it entered into a tax sharing agreement which governs the Company’s and CoreLogic’s respective rights, responsibilities and obligations for certain tax related matters. At June 30, 2017 and December 31, 2016, the Company had a net payable to CoreLogic of $12.9 million and $16.3 million, respectively, related to tax matters prior to the spin-off. This amount is included in the Company’s condensed consolidated balance sheets in accounts payable and accrued liabilities. The decrease during the current year was primarily due to payments made for tax matters prior to the spin-off. The Company evaluates the realizability of its deferred tax assets by assessing the valuation allowance and makes adjustments to the allowance as necessary. The factors used to assess the likelihood of realization include the Company’s forecast of future taxable income and available tax planning strategies that could be implemented to realize the deferred tax assets. The Company’s ability or failure to achieve forecasted taxable income in the applicable taxing jurisdictions could affect the ultimate realization of deferred tax assets. Based on actual future operating results in certain jurisdictions, it is possible that the current valuation allowance positions of those jurisdictions could be adjusted in the next 12 months. As of June 30, 2017 and December 31, 2016, the liability for income taxes associated with uncertain tax positions was $18.5 million and $18.1 million, respectively. The net increase in the liability during 2017 was primarily attributable to reserves for tax positions taken by the Company. As of June 30, 2017 and December 31, 2016, the liability could be reduced by $5.7 million due to offsetting tax benefits associated with the correlative effects of potential adjustments, including timing adjustments and state income taxes. The net amounts of $12.8 million and $12.4 million as of June 30, 2017 and December 31, 2016, respectively, if recognized, would favorably affect the Company’s effective tax rate. The Company’s continuing practice is to recognize interest and penalties, if any, related to uncertain tax positions in income tax expense. As of June 30, 2017 and December 31, 2016, the Company had accrued $4.3 million and $4.1 million, respectively, of interest and penalties (net of tax benefits of $2.0 million and $1.8 million, respectively) related to uncertain tax positions. It is reasonably possible that the amount of the unrecognized benefit with respect to certain of the Company’s unrecognized tax positions may significantly increase or decrease within the next 12 months. Any such change may be the result of ongoing audits or the expiration of federal and state statutes of limitations for the assessment of taxes. The Company, or one of its subsidiaries, files income tax returns in the U.S. federal jurisdiction, various state jurisdictions, and various non-U.S. jurisdictions. The primary non-federal jurisdictions are California, Canada, India and the United Kingdom. During 2016, the Company concluded U.S. federal income tax examinations for calendar years 2005 through 2013. The Company is generally no longer subject to U.S. federal, state and non-U.S. income tax examinations for years prior to 2005.
