Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies: The accompanying unaudited condensed consolidated financial statements have been prepared on the basis of accounting principles generally accepted in the U.S. (“U.S. GAAP”). The preparation of financial statements in conformity with these accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant estimates include acquisition purchase price allocations, the fair value of goodwill, the realization of deferred tax assets and liabilities, acquisition related liabilities, fair value of stock based compensation for stock options granted, and assets and liabilities for pension and postretirement benefits. Actual results may ultimately differ from those estimates. The condensed consolidated financial statements as of March 31, 2017 and for the three months ended March 31, 2017 and 2016 , in the opinion of management, include all adjustments, consisting of normal recurring items, to present fairly the Company’s financial position, results of operations and cash flows. The operating results for the three months ended March 31, 2017 are not necessarily indicative of the results to be expected for the full year. The condensed consolidated financial statements and related notes for the three months ended March 31, 2017 have been prepared on the same basis as and should be read in conjunction with the annual report on Form 10-K for the year ended December 31, 2016 . Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules of the Securities and Exchange Commission (“SEC”). The Company believes the disclosures made are adequate to keep the information presented from being misleading. Recent Accounting Pronouncements In August 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date ("ASU No. 2015-14"). The amendments in this update defer the effective date of ASU No. 2014-09, Revenue from Contracts with Customers , for all entities by one year. Public business entities will apply the guidance in ASU No. 2015-14 for annual reporting periods beginning after December 15, 2017. The Company is currently evaluating ASU No. 2015-14 and has not determined the impact this standard may have on its financial statements nor decided upon the method of adoption. The Company is still finalizing its analysis to quantify the adoption impact of the provisions of the new standard. The Company believes that it is following an appropriate timeline to allow for proper recognition, presentation and disclosure upon adoption of ASU No. 2015-14 effective the beginning of fiscal 2018. In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting (“ASU No. 2016-09”). The objective of this update is to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The Company adopted the guidance prospectively for the income statement impact of income taxes and has retrospectively applied the guidance to the condensed consolidated statements of cash flows for the impact of excess tax benefits on January 1, 2017 in accordance with ASU No. 2016-09. The presentation requirements for cash flows related to employee taxes paid for withheld shares had no impact to any of the periods presented in the condensed consolidated statements of cash flows, since such cash flows have historically been presented in financing activities. The treatment of forfeitures has not changed as the Company is electing to continue the current process of estimating the number of forfeitures. Accordingly, excess tax benefits from exercised stock options in the first quarter were recorded as income tax benefit in the condensed consolidated statements of operations and presented as an operating activity on the condensed consolidated statements of cash flows for the three months ended March 31, 2017. There was no cumulative-effect adjustment required to retained earnings under the prospective method as of the beginning of the year because all tax benefits had been previously recognized when the tax deductions related to stock compensation were utilized to reduce tax payable. The Company is not recording deferred tax assets or tax liabilities as the result of the adoption of ASU 2016-09.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements: Certain assets and liabilities of the Company are reported at fair value in the accompanying condensed consolidated balance sheets. To increase consistency and comparability of assets and liabilities recorded at fair value, ASC 820-10, Fair Value Measurements (“ASC 820-10”), established a three-level fair value hierarchy to prioritize the inputs to valuation techniques used to measure fair value. ASC 820-10 requires disclosures detailing the extent to which companies measure assets and liabilities at fair value, the methods and assumptions used to measure fair value and the effect of fair value measurements on earnings. In accordance with ASC 820-10, the Company applied the following fair value hierarchy: Level 1 - Assets or liabilities for which the identical item is traded on an active exchange, such as publicly-traded instruments. Level 2 - Assets and liabilities valued based on observable market data for similar instruments. Level 3 - Assets or liabilities for which significant valuation assumptions are not readily observable in the market; instruments valued based on the best available data, some of which are internally-developed, and considers risk premiums that market participants would require. The fair values of cash and cash equivalents, accounts receivable, securities accounted for under ASC 323-10-25, accounts payable and accrued liabilities, and short-term debt approximate their carrying amounts because of the short-term nature of these instruments. The following table summarizes fair value measurements by level for cash equivalents and registered investment companies that were measured at fair value on a recurring basis: Quoted Prices in Active Markets for Identical Assets (Level 1) March 31, 2017 Registered investment companies (1) $ 3.6 December 31, 2016 Registered investment companies (1) $ 3.4 ______________________ (1) Registered investment companies are classified as available-for-sale securities and are valued using quoted prices in active markets multiplied by the number of shares owned. The Company has not elected to carry its subordinated promissory note receivable and long-term debt at fair value. The carrying value of the subordinated promissory note receivable represents amortized cost and has been included in "Other assets" in the accompanying condensed consolidated balance sheets. The carrying value of the long-term debt represents amortized cost less unamortized discount and debt issuance costs. The Company assesses the fair value of these financial instruments based on an estimate of interest rates available to the Company for financial instruments with similar features, the Company’s current credit rating and spreads applicable to the Company. The following table summarizes the carrying value and estimated fair value of these financial instruments as of March 31, 2017 and December 31, 2016 , respectively: 2017 2016 Fair Value Hierarchy Carrying Value Estimated Fair Value Carrying Value Estimated Fair Value Financial instruments not carried at fair value: Subordinated promissory note receivable Level 2 $ 84.7 $ 77.0 $ 84.1 $ 76.8 Long-term debt excluding capitalized Level 2 $ 2,278.2 $ 2,415.5 $ 2,277.3 $ 2,402.6

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations: On June 1, 2016, the Company sold 100 percent of the stock of its healthcare business, Verisk Health ("Verisk Health"), in exchange for a purchase price that consisted of $714.6 million of cash consideration after a working capital adjustment of $5.4 million , a subordinated promissory note with a face value of $100.0 million and an eight year maturity (the "Note"), and other contingent consideration (collectively, the "Sale"). Results of operations for the healthcare business are reported as a discontinued operation for the three months ended March 31, 2016 . The Note has a stated interest rate of 9.0% per annum, increasing to 11.0% per annum at the earlier of specified refinancings or acquisitions, or the fourth anniversary of the closing of the Sale. Interest shall accrue from the closing date and on each anniversary of the Sale until the Note is paid in full on the unpaid principal amount of the Note outstanding at the interest rate in effect (computed on the basis of a 360-day year of twelve 30-day months). On each anniversary of the Sale, accrued interest shall be paid in kind by adding the amount of such accrued interest to the outstanding principal amount of the Note. The issuer of the Note may, at its option at any time prior to the maturity date, prepay any, or all, of the principal amount of the Note, plus accrued but unpaid interest as of the elected prepayment date, without any premium or penalty. There is a mandatory prepayment of the Note as a result of (i) the proceeds of a specified dividend recapitalization received by the issuer, (ii) the consummation of a change of control of the issuer, or (iii) the sale, transfer or other disposition by the parent of the issuer of more than 10.0% of the capital stock of the issuer. As of March 31, 2017 , the Company had a receivable of $84.7 million outstanding under the Note. The carrying value of the Note represents amortized cost. The fair value of the Note is based on management estimates with the assistance of valuations performed by third party specialists, discounted cash flow analysis based on current market conditions and assumptions that the Note would be paid in full at maturity, including accrued interest, with no prepayment election. Refer to Note 3 Fair Value Measurements for further discussion. The Company also received a 10.0% non-participating interest in the issuer's stock, the exercise value of which will be contingent on the parent of the issuer realizing a specified rate of return on its investment. As of March 31, 2017 , the Company had an equity investment of $8.4 million related to such interest accounted for in accordance with ASC 323-10-25, The Equity Method of Accounting for Investments in Common Stock ("ASC 323-10-25"). The value of the equity investment has been included in “Other assets” in the accompanying condensed consolidated balance sheets. The following table summarizes the results from the discontinued operation for the three months ended March 31 : 2017 2016 Revenues from discontinued operations $ — $ 69.2 Expenses: Cost of revenues (exclusive of items shown separately below) — 44.5 Selling, general and administrative — 10.1 Depreciation and amortization of fixed assets — 7.0 Amortization of intangible assets — 5.9 Total expenses — 67.5 Operating income — 1.7 Other income: Investment income and others, net — 0.1 Total other income — 0.1 Income from discontinued operations before income taxes — 1.8 Provision for income taxes (1) — (18.9 ) Loss from discontinued operations, net of tax $ — $ (17.1 ) (1) Included in the provision for income taxes, for the three months ended March 31, 2016 , is a charge of $18.2 million primarily resulting from the recognition of a deferred tax liability of $17.6 million associated with the estimated stock basis difference in Verisk Health. Net cash provided by operating activities and net cash used in investing activities from the discontinued operation for the three months ended March 31 are presented below: 2017 2016 Net cash provided by operating activities $ — $ 22.1 Net cash used in investing activities $ — $ (5.5 ) The Company has also entered into a transitional service agreement ("TSA") with the buyer of Verisk Health. Under the TSA, the Company provides various services for terms generally up to 12 months from the acquisition date and receives a level of cost reimbursement from the buyer.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Goodwill and Intangible Assets: The following is a summary of the change in goodwill from December 31, 2016 through March 31, 2017 , both in total and as allocated to the Company’s operating segments: Risk Assessment Decision Analytics Total Goodwill at December 31, 2016 (1) $ 71.3 $ 2,506.8 $ 2,578.1 Current year acquisitions 35.1 16.9 52.0 Purchase accounting reclassification (0.2 ) 0.3 0.1 Foreign currency translation (0.1 ) 23.2 23.1 Goodwill at March 31, 2017 (1) $ 106.1 $ 2,547.2 $ 2,653.3 ______________________ (1) These balances are net of accumulated impairment charges of $3.2 million that occurred prior to December 31, 2016 . Goodwill and intangible assets with indefinite lives are subject to impairment testing annually as of June 30, or whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. Goodwill impairment testing compares the carrying value of each reporting unit to its fair value. If the fair value of the reporting unit exceeds the carrying value of the net assets, including goodwill assigned to that reporting unit, goodwill is not impaired. If the carrying value of the reporting unit’s net assets including goodwill exceeds the fair value of the reporting unit, then the Company will determine the implied fair value of the reporting unit’s goodwill. If the carrying value of a reporting unit’s goodwill exceeds its implied fair value, then an impairment loss is recorded for the difference between the carrying amount and the implied fair value of goodwill. The Company completed the required annual impairment test as of June 30, 2016, and concluded that there was no impairment of goodwill. The Company’s intangible assets and related accumulated amortization consisted of the following: Weighted Average Useful Life Cost Accumulated Amortization Net March 31, 2017 Technology-based 7 years $ 326.4 $ (201.2 ) $ 125.2 Marketing-related 17 years 232.2 (50.7 ) 181.5 Contract-based 6 years 5.0 (5.0 ) — Customer-related 14 years 498.0 (138.5 ) 359.5 Database-related 20 years 398.7 (37.7 ) 361.0 Total intangible assets $ 1,460.3 $ (433.1 ) $ 1,027.2 December 31, 2016 Technology-based 7 years $ 310.9 $ (196.6 ) $ 114.3 Marketing-related 17 years 227.5 (47.5 ) 180.0 Contract-based 6 years 5.0 (5.0 ) — Customer-related 14 years 483.1 (128.5 ) 354.6 Database-related 20 years 393.9 (32.0 ) 361.9 Total intangible assets $ 1,420.4 $ (409.6 ) $ 1,010.8 Amortization expense related to intangible assets for the three months ended March 31, 2017 and 2016 was $22.3 million and $23.9 million , respectively. Estimated amortization expense for the remainder of 2017 and the years through 2022 and thereafter for intangible assets subject to amortization is as follows: Year Amount 2017 $ 69.1 2018 92.4 2019 91.7 2020 90.1 2021 79.7 2022 and thereafter 604.2 $ 1,027.2

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes: The Company’s effective tax rate for the three months ended March 31, 2017 was 32.47% compared to the effective tax rate for the three months ended March 31, 2016 of 31.69% . The effective tax rate for the three months ended March 31, 2017 is higher than the March 31, 2016 effective tax rate primarily due to reduced tax benefits in the current period resulting from legislation enacted in the U.K., partially offset by the tax rate benefit of adopting ASU No. 2016-09. The difference between statutory tax rates and the Company’s effective tax rate is primarily attributable to state taxes and tax benefits related to the Wood Mackenzie acquisition.

Equity [Abstract]
Stockholders' Equity	Stockholders’ Equity: The Company has 2,000,000,000 shares of authorized common stock. The common shares have rights to any dividend declared by the board of directors (the "Board"), subject to any preferential or other rights of any outstanding preferred stock, and voting rights to elect all fourteen members of the Board. The Company has 80,000,000 shares of authorized preferred stock, par value $0.001 per share. The preferred shares have preferential rights over the common shares with respect to dividends and net distribution upon liquidation. The Company did not issue any preferred shares as of March 31, 2017 . Share Repurchase Program Since the introduction of the Repurchase Program as a feature of the Company's capital management strategies in 2010, the Company has authorized repurchases of up to $2,800.0 million of its common stock and has repurchased shares with an aggregate value of $2,268.0 million . The Company repurchased 1,280,320 shares of common stock with an aggregate value of $104.0 million during the three months ended March 31, 2017 . As of March 31, 2017 , the Company had $532.0 million available to repurchase shares. The Company has no obligation to repurchase stock under this program and intends to use this authorization as a means of offsetting dilution from the issuance of shares under the KSOP, the Verisk 2013 Equity Incentive Plan (the “2013 Incentive Plan”), the Verisk 2009 Equity Incentive Plan (the “2009 Incentive Plan”), and the ISO 1996 Incentive Plan (the “1996 Incentive Plan”), while providing flexibility to repurchase additional shares if warranted. This authorization has no expiration date and may be increased, reduced, suspended, or terminated at any time. Shares that are repurchased under the Repurchase Program will be recorded as treasury stock and will be available for future issuance. Treasury Stock As of March 31, 2017 , the Company’s treasury stock consisted of 378,111,339 shares of common stock. During the three months ended March 31, 2017 , the Company reissued 256,247 shares of common stock from the treasury shares at a weighted average price of $7.79 per share. Earnings Per Share (“EPS”) Basic EPS is computed by dividing income from continuing operations, loss from discontinued operations and net income, respectively, by the weighted average number of common shares outstanding during the period. The computation of diluted EPS is similar to the computation of basic EPS except that the denominator is increased to include the number of additional common shares that would have been outstanding, using the treasury stock method, if the dilutive potential common shares, including stock options, nonvested restricted stock awards, and nonvested restricted stock units, had been issued. The following is a reconciliation of the numerators and denominators of the basic and diluted EPS computations for the three months ended March 31, 2017 and 2016 : Three Months Ended March 31, 2017 2016 Numerator used in basic and diluted EPS: Income from continuing operations $ 108.8 $ 109.7 Loss from discontinued operations (Note 5) — (17.1 ) Net income $ 108.8 $ 92.6 Denominator: Weighted average number of common shares used in basic EPS 166,442,991 168,453,750 Effect of dilutive shares: Potential common shares issuable from stock options and stock awards 3,707,871 3,027,134 Weighted average number of common shares and dilutive potential common 170,150,862 171,480,884 The potential shares of common stock that were excluded from diluted EPS were 1,282,164 and 1,674,484 for the three months ended March 31, 2017 and 2016 , respectively, because the effect of including these potential shares was anti-dilutive. Accumulated Other Comprehensive Losses The following is a summary of accumulated other comprehensive losses as of March 31, 2017 and December 31, 2016 : 2017 2016 Foreign currency translation adjustment $ (528.3 ) $ (561.4 ) Unrealized holding gains on available-for-sale securities, net of tax 0.4 0.3 Pension and postretirement adjustment, net of tax (89.0 ) (89.7 ) Accumulated other comprehensive losses $ (616.9 ) $ (650.8 ) The before tax and after tax amounts of other comprehensive income for the three months ended March 31, 2017 and 2016 are summarized below: Before Tax Tax (Expense) Benefit After Tax For the Three Months Ended March 31, 2017 Foreign currency translation adjustment $ 33.1 $ — $ 33.1 Unrealized holding gain on available-for-sale securities before 0.2 (0.1 ) 0.1 Amount reclassified from accumulated other comprehensive losses — — — Unrealized holding gain on available-for-sale securities 0.2 (0.1 ) 0.1 Pension and postretirement adjustment before reclassifications 2.3 (0.9 ) 1.4 Amortization of net actuarial loss and prior service benefit (1.2 ) 0.5 (0.7 ) Pension and postretirement adjustment 1.1 (0.4 ) 0.7 Total other comprehensive gain $ 34.4 $ (0.5 ) $ 33.9 For the Three Months Ended March 31, 2016 Foreign currency translation adjustment $ (75.3 ) $ — $ (75.3 ) Unrealized holding gain on available-for-sale securities before 0.4 (0.2 ) 0.2 Amount reclassified from accumulated other comprehensive losses (0.2 ) 0.1 (0.1 ) Unrealized holding gain on available-for-sale securities 0.2 (0.1 ) 0.1 Pension and postretirement adjustment before reclassifications 1.7 (0.7 ) 1.0 Amortization of net actuarial loss and prior service benefit (0.9 ) 0.4 (0.5 ) Pension and postretirement adjustment 0.8 (0.3 ) 0.5 Total other comprehensive loss $ (74.3 ) $ (0.4 ) $ (74.7 ) _______________ (1) This accumulated other comprehensive loss component, before tax, is included under “Investment income and others, net” in the accompanying condensed consolidated statements of operations.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Equity Compensation Plans	Equity Compensation Plans: ISO 401(k) Savings and Employee Stock Ownership Plan ("KSOP") The Company has established the KSOP for the benefit of eligible employees in the U.S. and Puerto Rico. The KSOP includes both an employee savings component and an employee stock ownership component. The purpose of the combined plan is to enable the Company’s employees to participate in a tax-deferred savings arrangement under Internal Revenue Service Code Sections 401(a) and 401(k), and to provide employee equity participation in the Company through the employee stock ownership plan accounts. For the three months ended March 31, 2017 , the Company opted to fund the 401(k) matching contributions in cash in lieu of issuance of common stock from treasury shares. For the three months ended March 31, 2017 , the Company matched cash contribution of $4.9 million and recognized it as KSOP compensation expense. For the three months ended March 31, 2016 , the Company matched 43,071 shares of common stock at a weighted average per price of $78.73 and recognized as KSOP compensation expense. Equity Compensation Plans All of the Company’s outstanding stock options and restricted stock awards are covered under the 2013 Incentive Plan, 2009 Incentive Plan or the 1996 Incentive Plan. Awards under the 2013 Incentive Plan may include one or more of the following types: (i) stock options (both nonqualified and incentive stock options), (ii) stock appreciation rights, (iii) restricted stock, (iv) restricted stock units, (v) performance awards, (vi) other share based awards, and (vii) cash. Employees, directors and consultants are eligible for awards under the 2013 Incentive Plan. The Company issued common stock under these plans from the Company’s treasury shares. As of March 31, 2017 , there were 8,739,754 shares of common stock reserved and available for future issuance under the 2013 Incentive Plan. Cash received from stock option exercises for the three months ended March 31, 2017 and 2016 was $7.5 million and $4.7 million, respectively. The Company granted equity awards to key employees of the Company. The nonqualified stock options have an exercise price equal to the closing price of the Company’s common stock on the grant date, with a ten -year contractual term. The fair value of the restricted stock is determined using the closing price of the Company’s common stock on the grant date. The restricted stock is not assignable or transferable until it becomes vested. The Company recognizes the expense of the equity awards ratably over the vesting period. A summary of the equity awards granted for the three months ended March 31, 2017 and on April 1, 2017 is presented below. Grant Date Service Vesting Period Stock Options Restricted Stock January 1 to March 31, 2017 Four-year graded vesting 2,669 525 April 1, 2017 Four-year graded vesting 1,300,007 248,489 April 1, 2017 Two-year graded vesting 47,030 11,272 1,349,706 260,286 The fair value of the stock options granted for the three months ended March 31, 2017 was estimated using a Black-Scholes valuation model that uses the weighted average assumptions noted in the following table. There were no stock options granted for the three months ended March 31, 2016 . 2017 Option pricing model Black-Scholes Expected volatility 19.16 % Risk-free interest rate 1.84 % Expected term in years 4.5 Dividend yield — % Weighted average grant date fair value per stock option $ 16.09 The expected term for the stock options granted was estimated based on studies of historical experience and projected exercise behavior. However, for certain awards granted, for which no historical exercise pattern exists, the expected term was estimated using the simplified method. The risk-free interest rate is based on the yield of U.S. Treasury zero coupon securities with a maturity equal to the expected term of the equity award. The volatility factor is calculated using historical daily closing prices over the most recent period that is commensurate with the expected term of the stock option award. The expected dividend yield was based on the Company’s expected annual dividend rate on the date of grant. A summary of the stock options outstanding and exercisable as of December 31, 2016 and March 31, 2017 and changes during the interim period are presented below: Number Weighted Aggregate Outstanding at December 31, 2016 8,770,917 $ 46.67 $ 302.6 Granted 2,669 $ 82.01 Exercised (239,478 ) $ 30.42 $ 12.6 Cancelled or expired (36,241 ) $ 73.96 Outstanding at March 31, 2017 8,497,867 $ 47.02 $ 290.0 Exercisable at March 31, 2017 5,927,409 $ 35.69 $ 269.4 Exercisable at December 31, 2016 6,148,349 $ 35.35 $ 281.7 Intrinsic value for stock options is calculated based on the exercise price of the underlying awards and the quoted price of Verisk common stock as of the reporting date. The Company adopted ASU No. 2016-09 prospectively on January 1, 2017 and excess tax benefits from exercised stock options were recorded as income tax benefit in the condensed consolidated statements of operations. This tax benefit is calculated as the excess of the intrinsic value of options exercised and restricted stock lapsed in excess of compensation recognized for financial reporting purposes. Prior to the adoption of ASU No. 2016-09, for the three months ended March 31, 2016 , the Company recorded excess tax benefits of $1.7 million in "Additional paid-in capital" in the accompanying condensed consolidated balance sheets. Stock based compensation expense for the three months ended March 31, 2017 and 2016 was $6.5 million and $5.5 million , respectively. The Company estimates expected forfeitures of equity awards at the date of grant and recognizes compensation expense only for those awards that the Company expects to vest. The forfeiture assumption is ultimately adjusted to the actual forfeiture rate. Changes in the forfeiture assumptions may impact the total amount of expense ultimately recognized over the requisite service period and may impact the timing of expense recognized over the requisite service period. A summary of the status of the restricted stock awarded under the 2013 Incentive Plan as of December 31, 2016 and March 31, 2017 and changes during the interim period are presented below: Number Weighted Average Grant Outstanding at December 31, 2016 537,667 $ 73.34 Granted 525 $ 82.01 Vested (8,444 ) $ 80.03 Forfeited (6,580 ) $ 73.59 Outstanding at March 31, 2017 523,168 $ 73.26 The Company’s employee stock purchase plan (“ESPP”) offers eligible employees the opportunity to purchase shares of the Company’s common stock at a discount of its fair market value at the time of purchase. During the three months ended March 31, 2017 and 2016 , the Company issued 8,325 and 9,257 shares of common stock at a weighted discounted price of $77.08 and $75.92 for the ESPP, respectively. As of March 31, 2017 , there was $52.6 million of total unrecognized compensation costs, exclusive of the impact of vesting upon retirement eligibility, related to nonvested share-based compensation arrangements granted under the 2009 and 2013 Incentive Plans. That cost is expected to be recognized over a weighted average period of 2.44 years. As of March 31, 2017 , there were 2,570,458 and 523,168 nonvested stock options and restricted stock, respectively, of which 2,125,224 and 428,789 are expected to vest. The total grant date fair value of options vested during the three months ended March 31, 2017 and 2016 was $3.6 million and $3.3 million , respectively. The total grant date fair value of restricted stock vested during the three months ended March 31, 2017 and 2016 was $3.8 million and $3.3 million , respectively.

Pension and Postretirement Benefits	Pension and Postretirement Benefits: The Company maintained a frozen qualified defined benefit pension plan for certain of its employees through membership in the Pension Plan for Insurance Organizations (the “Pension Plan”), a multiple-employer trust. The Company has applied a cash balance formula to determine future benefits. Under the cash balance formula, each participant has an account, which is credited annually based on the interest earned on the previous year-end cash balance. The Company also has a frozen non-qualified supplemental cash balance plan (“SERP”) for certain employees. The SERP is funded from the general assets of the Company. The Company also provides certain healthcare and life insurance benefits to certain qualifying active and retired employees. The Postretirement Health and Life Insurance Plan (the “Postretirement Plan”), which has been frozen, is contributory, requiring participants to pay a stated percentage of the premium for coverage. The components of net periodic (benefit) cost for the three months ended March 31, are summarized below: Pension Plan and SERP Postretirement Plan For the Three Months Ended March 31, 2017 2016 2017 2016 Interest cost $ 4.2 $ 4.8 $ 0.1 $ 0.1 Expected return on plan assets (7.8 ) (8.0 ) (0.1 ) (0.1 ) Amortization of prior service cost 0.1 — — — Amortization of net actuarial loss 1.0 0.8 0.1 0.1 Net periodic (benefit) cost $ (2.5 ) $ (2.4 ) $ 0.1 $ 0.1 Employer contributions, net $ 0.2 $ 0.3 $ 0.4 $ — The expected contributions to the Pension Plan, SERP and Postretirement Plan for the year ending December 31, 2017 are consistent with the amounts previously disclosed as of December 31, 2016 .

Segment Reporting

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting: ASC 280-10, Disclosures About Segments of an Enterprise and Related Information (“ASC 280-10”), establishes standards for reporting information about operating segments. ASC 280-10 requires that a public business enterprise reports financial and descriptive information about its operating segments. Operating segments are components of an enterprise for which separate financial information is available that is evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to allocate resources and in assessing performance. The Company’s President and Chief Executive Officer is identified as the CODM as defined by ASC 280-10. Consistent with the internal management of the Company’s business operations based on service offerings, the Company is organized into the following two operating segments, which are also the Company’s reportable segments: Decision Analytics: The Company develops solutions that its customers use to analyze the key processes in managing risk: ‘prediction of loss’, ‘detection and prevention of fraud’ and ‘quantification of loss’. The Company’s combination of algorithms and analytic methods incorporates its proprietary data to generate solutions. In most cases, the Company’s customers integrate the solutions into their models, formulas or underwriting criteria in order to predict potential loss events, such as hurricanes and earthquakes claims. The Company develops catastrophe and extreme event models and offers solutions covering natural and man-made risks, including acts of terrorism. The Company also develops solutions that allow customers to quantify costs after loss events occur. Fraud solutions include data on claim histories, analysis of claims to find emerging patterns of fraud, and identification of suspicious claims in the insurance sectors. The Company offers services and a suite of solutions to a client base that includes credit and debit card issuers, retail bank and other consumer financial services providers, payment processors, insurance companies and other industry stakeholders. The Company further leverages predictive models and proprietary data to advise customers to make asset investment and portfolio allocation decisions in the global energy market. The Company discloses revenue within this segment based on the industry vertical groupings of insurance, energy and specialized markets, and financial services. On June 1, 2016, the Company sold its healthcare business, Verisk Health, which was part of the Decision Analytics segment. Results of operations for the healthcare business are reported as a discontinued operation for the three months ended March 31, 2016. Refer to Note 5 for more information. Risk Assessment: The Company is the leading provider of statistical, actuarial and underwriting data for the U.S. P&C insurance industry. The Company’s databases include cleansed and standardized records describing premiums and losses in insurance transactions, casualty and property risk attributes for commercial buildings and their occupants and fire suppression capabilities of municipalities. The Company uses this data to create policy language and proprietary risk classifications that are industry standards and to generate prospective loss cost estimates used to price insurance policies. The two aforementioned operating segments represent the segments for which discrete financial information is available and upon which operating results are regularly evaluated by the CODM in order to assess performance and allocate resources. The Company uses EBITDA as the profitability measure for making decisions regarding ongoing operations. EBITDA is net income before interest expense, provision for income taxes, depreciation and amortization of fixed and intangible assets. EBITDA is the measure of operating results used to assess corporate performance and optimal utilization of debt and acquisitions. Operating expenses consist of direct and indirect costs principally related to personnel, facilities, software license fees, consulting, travel, and third-party information services. Indirect costs are generally allocated to the segments using fixed rates established by management based upon estimated expense contribution levels and other assumptions that management considers reasonable. The Company does not allocate interest expense and provision for income taxes, since these items are not considered in evaluating the segment’s overall operating performance. In addition, the CODM does not evaluate the financial performance of each segment based on assets.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies: The Company is a party to legal proceedings with respect to a variety of matters in the ordinary course of business, including the matters described below. With respect to ongoing matters, the Company is unable, at the present time, to determine the ultimate resolution of or provide a reasonable estimate of the range of possible loss attributable to these matters or the impact they may have on the Company’s results of operations, financial position or cash flows. This is primarily because the matters are generally in early stages and discovery has either not commenced or been completed. Although the Company believes it has strong defenses and intends to vigorously defend these matters, the Company could in the future incur judgments or enter into settlements of claims that could have a material adverse effect on its results of operations, financial position or cash flows. Intellicorp Records, Inc. Litigation On September 9, 2015, the Company was served with a nationwide putative class action complaint filed in the Court of Common Pleas, Cuyahoga County in Ohio naming the Company’s subsidiary Intellicorp Records, Inc. (“Intellicorp”) titled Sherri Legrand v. Intellicorp Records, Inc. and The Cato Corporation et al. Defendants removed the case to the United States District Court for the Northern District of Ohio on October 8, 2015. Plaintiffs filed their First Amended Class Action Complaint on November 5, 2015 (“Amended Complaint”), which like the prior complaint claims violations of the Fair Credit Reporting Act ("FCRA") and alleges two putative class claims against Intellicorp, namely (i) a section 1681k(a) claim on behalf of all individuals who were the subjects of consumer reports furnished by Intellicorp, which contained public record information in the “Government Sanctions” section of the report on or after September 4, 2013 and continuing through the date the class list is prepared, and (ii) a section 1681e(b) claim on behalf of all individuals who were the subjects of consumer reports furnished by Intellicorp, which contained public record information in the “Government Sanctions” section of the report where the address or social security number of the subject of the report do not match the social security number or address contained in the government database on or after September 4, 2013 and continuing through the date the class list is prepared. Count I of the Amended Complaint alleges that defendant Cato violated the FCRA by procuring consumer reports on the plaintiff and other class members without making the stand-alone disclosure required by FCRA section 1681b(b)(2)(A)(i). Counts II and III allege that Intellicorp violated the FCRA section 1681e (b) by failing to follow reasonable procedures to assure maximum accuracy of the adverse information included in its consumer reports and FCRA section 1681k (a) by failing to maintain strict procedures to assure that the public record information reported, which was likely to have an adverse effect on the consumer was complete and up to date, respectively. The Amended Complaint alleges that defendants acted willfully and seeks statutory damages for the classes in an amount not less than one hundred dollars and not more than one thousand dollars per violation, punitive damages, equitable relief, costs and attorney’s fees. On April 24, 2017, the parties agreed to resolve the litigation in a Settlement Agreement and Release and plaintiffs filed their Motion for Preliminary Approval of the settlement on the same day. The settlement provides for a non-material cash payment by the Company, as well as certain non-monetary relief. The District Court granted the Motion for Preliminary Approval on April 25, 2017. Xactware Solutions, Inc. Patent Litigation On October 8, 2015, the Company was served with a summons and complaint in an action titled Eagle View Technologies, Inc. and Pictometry International Group, Inc. v. Xactware Solutions, Inc. and Verisk Analytics, Inc. filed in the United States District Court for the District of New Jersey. The complaint alleges that the Company’s Roof InSight, Property InSight and Aerial Sketch products infringe seven patents owned by Eagle View and Pictometry namely, Patent Nos. 436, 840, 152, 880, 770, 732 and 454 (collectively the “Patents-in-Suit”). On November 30, 2015, plaintiffs filed a First Amended Complaint adding Patent Nos. 376 and 737 to the Patents in Suit. The First Amended Complaint seeks an entry of judgment by the Court that defendants have and continue to directly infringe and/or indirectly infringe, by way of inducement the Patents-in-Suit, permanent injunctive relief, damages, costs and attorney’s fees. At this time, it is not possible to determine the ultimate resolution of, or estimate the liability related to this matter. Interthinx, Inc. Litigation On April 20, 2015, the Company was served with a putative class action titled John Weber v. Interthinx, Inc. and Verisk Analytics, Inc. The plaintiff, a former employee of the Company’s former subsidiary Interthinx, Inc. in Missouri, filed the class action complaint in the United States District Court for the Eastern District of Missouri on behalf of all review appraisers and individuals holding comparable positions with different titles who were employed by Interthinx for the last three years nationwide and who were not paid overtime wages. The class complaint claims that the review appraiser employees were misclassified as exempt employees and, as a result, were denied certain wages and benefits that would have been received if they were properly classified as non-exempt employees. It pleads a Collective Action under section 216(b) of the Fair Labor Standards Act for unpaid overtime and seeks overtime wages, liquidated damages, declaratory relief, interest, costs and attorneys’ fees. On March 11, 2014, the Company sold 100 percent of the stock of Interthinx, Inc. The parties agreed to resolve this matter with the Company’s contribution of a non-material amount in the Class Action Settlement Agreement executed on November 8, 2016. For settlement purposes only, this matter was consolidated with a related action pending in the Los Angeles Superior Court in which the Company is not a party, titled Sager v. Interthinx. On February 21, 2017, the Los Angeles Superior Court approved the settlement at the preliminary approval hearing and the final approval hearing is scheduled for June 15, 2017. Insurance Services Office, Inc. Litigation ACORD Matter On August 1, 2014 the Company was served with an Amended Complaint filed in the United States District Court for the District of Colorado titled Snyder, et. al. v. ACORD Corp., et al. The action is brought by nineteen individual plaintiffs, on their own behalf and on behalf of a putative class, against more than 120 defendants, including the Company and ISO. Except for the Company, ISO and the defendant Acord Corporation, which provides standard forms to assist in insurance transactions, most of the other defendants are property and casualty insurance companies that plaintiffs claim conspired to underpay property damage claims. Plaintiffs claim that the Company and ISO, along with all of the other defendants, violated state and federal antitrust and racketeering laws as well as state common law. On September 8, 2014, the Court entered an Order striking the Amended Complaint and granting leave to the plaintiffs to file a new complaint. On October 13, 2014, plaintiffs filed their Second Amended Complaint, which was re-filed by plaintiffs to correct errors as the Third Amended Complaint. The Third Amended Complaint similarly alleges that the defendants conspired to underpay property damage claims, but does not specifically allege what role the Company or ISO played in the alleged conspiracy. It claims that the Company and ISO, along with all of the other defendants, violated state and federal antitrust and racketeering laws as well as state common law, and seeks all available relief including injunctive, statutory, actual and punitive damages as well as attorneys’ fees. On January 15, 2016, the Court granted defendants’ motions to dismiss all claims asserted in the Third Amended Complaint. Plaintiffs filed a motion for reconsideration of this dismissal on February 16, 2016. The Court granted defendants’ motion to strike the motion for reconsideration on March 2, 2016 and gave plaintiffs leave to file another motion for reconsideration in accordance with the rules which plaintiffs filed on March 11, 2016 and, which was denied by the Court on April 25, 2016. On April 1, 2016, plaintiffs also filed a Notice of Appeal of the Court’s January 15, 2016 Order, which dismissed all claims in the Third Amended Complaint. Plaintiffs also filed an appeal of the Court’s denial of the motion for reconsideration, which the Court of Appeals for the 10th Circuit consolidated with the appeal of the Court’s January 15, 2016 dismissal. Appellants filed their brief in support of the consolidated appeal on July 21, 2016 and Appellees filed their brief in response on September 21, 2016. On April 6, 2017, the Court of Appeals for the 10th Circuit affirmed the Court’s dismissal of the Third Amended Complaint. The time period for which Plaintiffs could move for a motion for reconsideration of the 10th Circuit’s affirmance or Petition the Supreme Court for a writ of certiorari has not expired. At this time, it is not possible to determine the ultimate resolution of, or estimate the liability related to this matter. Halloran Matter On February 19, 2016, the Company was served with a notice of a summons and complaint filed on January 29, 2016 against ISO and more than 100 insurers.in the U.S. District Court for the District of Connecticut titled Halloran et al. v. Harleysville Preferred Insurance Co. et al. As alleged in the First Amended Complaint, the putative class action is brought by four policyholders on behalf of a class of similarly situated policyholders in eastern Connecticut who allege that their homeowner’s insurance carriers have wrongfully denied or will deny their claims for damage to their homes caused by defective concrete. The lawsuit alleges a breach of contract claim against certain insurers and seeks declaratory relief as to more than 100 other insurers. It also alleges that ISO as the drafter of the standardized policy language at issue violated the Connecticut Unfair Trade Practices ("CUTPA") and the Connecticut Unfair Insurance Practices Act ("CUIPA"). The plaintiffs ask that the Court certify a class of persons similarly situated and seek relief in the form of the cost for the replacement of their concrete foundations, and a declaratory judgment that all of the defendant insurance carriers are obligated to provide coverage for claims resulting from the defective concrete as well as, attorneys’ fees, costs and interest. On March 17, 2016 plaintiffs filed a First Amended Complaint that named additional insurers as defendants. On May 6, 2016, plaintiffs filed a motion to amend the First Amended Complaint, indicating an intention to remove ISO and certain insurers as defendants and to add other insurers as defendants. While that motion was pending, plaintiffs sought leave to make further amendments to the complaint. On April 6, 2017, the Court granted plaintiffs leave to file a Substituted Third Amended Complaint, which does not name ISO as a defendant. That complaint was filed on April 7, 2017. Accordingly, ISO is no longer a defendant in this case.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In August 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date ("ASU No. 2015-14"). The amendments in this update defer the effective date of ASU No. 2014-09, Revenue from Contracts with Customers , for all entities by one year. Public business entities will apply the guidance in ASU No. 2015-14 for annual reporting periods beginning after December 15, 2017. The Company is currently evaluating ASU No. 2015-14 and has not determined the impact this standard may have on its financial statements nor decided upon the method of adoption. The Company is still finalizing its analysis to quantify the adoption impact of the provisions of the new standard. The Company believes that it is following an appropriate timeline to allow for proper recognition, presentation and disclosure upon adoption of ASU No. 2015-14 effective the beginning of fiscal 2018. In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting (“ASU No. 2016-09”). The objective of this update is to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The Company adopted the guidance prospectively for the income statement impact of income taxes and has retrospectively applied the guidance to the condensed consolidated statements of cash flows for the impact of excess tax benefits on January 1, 2017 in accordance with ASU No. 2016-09. The presentation requirements for cash flows related to employee taxes paid for withheld shares had no impact to any of the periods presented in the condensed consolidated statements of cash flows, since such cash flows have historically been presented in financing activities. The treatment of forfeitures has not changed as the Company is electing to continue the current process of estimating the number of forfeitures. Accordingly, excess tax benefits from exercised stock options in the first quarter were recorded as income tax benefit in the condensed consolidated statements of operations and presented as an operating activity on the condensed consolidated statements of cash flows for the three months ended March 31, 2017. There was no cumulative-effect adjustment required to retained earnings under the prospective method as of the beginning of the year because all tax benefits had been previously recognized when the tax deductions related to stock compensation were utilized to reduce tax payable. The Company is not recording deferred tax assets or tax liabilities as the result of the adoption of ASU 2016-09.
Investment	In addition to the available-for-sale securities above, the Company has equity investments in non-public companies in which the Company acquired non-controlling interests and for which no readily determinable market value exists. These securities were accounted for in accordance with ASC 323-10-25, The Equity Method of Accounting for Investments in Common Stock ("ASC 323-10-25").
Segment Reporting	ASC 280-10, Disclosures About Segments of an Enterprise and Related Information (“ASC 280-10”), establishes standards for reporting information about operating segments. ASC 280-10 requires that a public business enterprise reports financial and descriptive information about its operating segments.
Related Party Disclosures	The Company considers its stockholders that own more than 5.0% of the outstanding common stock to be related parties as defined within ASC 850, Related Party Disclosures . As of March 31, 2017 and December 31, 2016 , the Company had no material transactions with related parties owning more than 5.0% of its common stock, except for transactions with the KSOP as disclosed in Note 16 Compensation Plans of the Company's consolidated financial statements included in the 2016 Form 10-K filing.
