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, fair value of stock based compensation, assets and liabilities for pension and postretirement benefits, and the estimate for the allowance for doubtful accounts. Actual results may ultimately differ from those estimates. Certain reclassifications have been made related to the debt disclosure within the condensed consolidated financial statements and the notes to conform to the respective 2016 presentation in connection with the adoption of Accounting Standards Update ("ASU") 2015-03, Simplifying the Presentation of Debt Issuance Costs ("ASU No. 2015-03"). On March 31, 2016, the Company's healthcare business qualified as assets held-for-sale. Accordingly, the respective assets and liabilities have been classified as held-for-sale in the condensed consolidated balance sheet at December 31, 2015 . The Company's healthcare business was sold on June 1, 2016. The results of operations and the gain on sale of the Company's healthcare business are reported as a discontinued operation for the periods presented herein (See Note 6). The condensed consolidated financial statements as of June 30, 2016 and for the three and six months ended June 30, 2016 and 2015 , 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 and six months ended June 30, 2016 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 and six months ended June 30, 2016 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, 2015 . 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 April 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-03. The amendments in this update require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The Company adopted the guidance on January 1, 2016 and as a result, debt issuance costs of $22,275 were reclassified from "Other assets" to "Long-term debt" on the Company's condensed consolidated balance sheet as of December 31, 2015. In April 2015, the FASB issued ASU No. 2015-05, Customer's Accounting for Fees Paid in a Cloud Computing Arrangement ("ASU No. 2015-05"). This guidance is intended to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement, primarily to determine whether the arrangement includes a sale or license of software. The Company adopted the guidance on January 1, 2016. The adoption of ASU No. 2015-05 did not have a material impact on the Company's condensed consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments ("ASU No. 2015-16"). ASU No. 2015-16 requires, for business combinations, that the acquirer record, in the same period's financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The Company adopted the guidance on January 1, 2016. Adoption of this guidance did not have a material impact on the results of operations or financial position (see Note 5). In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU No. 2016-01”). The amendments in this update require all equity investments to be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under equity method of accounting or those that result in consolidation of the investee). The amendments allow equity investments that do not have readily determinable fair values to be remeasured at fair value either upon occurrence of an observable price change or upon identification of an impairment. The amendments in ASU No. 2016-01 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. For amendments applicable to the Company, early adoption is not permitted. The Company will conform to ASC No. 2016-01 in the condensed consolidated financial statements in future periods. In February 2016, the FASB issued ASU No. 2016-02, Leases ("ASU No. 2016-02"). This ASU amends the existing accounting considerations and treatments for leases through the creation of Topic 842, Leases , to increase transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet and disclosing key information about lease arrangements. The amendments in ASU No. 2016-02 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application of the amendments is permitted for all entities. The Company has decided not to early adopt ASU No. 2016-02 and is currently evaluating the impact the amendments may have on its condensed consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-07, Equity Method and Joint Ventures (“ASU No. 2016-07”). The amendments in the update eliminate the requirement that an entity retroactively adopt the equity method of accounting if an investment qualifies for use of the equity method as a result of an increase in the level of ownership or degree of influence. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of account as of the date the investment becomes qualified for equity method accounting. The amendments in ASU No. 2016-07 are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The Company has not elected to early adopt. The adoption of ASU No. 2016-07 is not expected to have a material impact on the Company’s condensed consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-08, Principal Versus Agent Considerations (“ASU No. 2016-08”). The amendments to this update are intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations. The amendments in ASU No. 2016-08 are effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is currently evaluating ASU No. 2016-08 and has not determined the impact this standard may have on its financial statements nor decided upon the method of adoption. 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 amendments in ASU No. 2016-09 are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any entity in any interim or annual period. The Company has not elected to early adopt. The Company is currently evaluating ASU No. 2016-09 and has not determined the impact this amendment may have on its financial statements. In April 2016, the FASB issued ASU No. 2016-10, Identifying Performance Obligations and Licensing (“ASU No. 2016-10”). The amendments in this update clarify the following two aspects of Accounting Standards Codification ("ASC") 606 ("ASC 606"), Revenue From Contracts With Customers : identifying performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. The amendments in ASU No. 2016-10 are effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is currently evaluating ASU No. 2016-10 and has not determined the impact this standard may have on its financial statements nor decided upon the method of adoption. In May 2016, the FASB issued ASU No. 2016-11, Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-16 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting (SEC Update) ("ASU No. 2016-11"). Specifically, registrants should not rely on the following SEC Staff Observer comments upon adoption of ASC 606: a. Revenue and Expense Recognition for Freight Services in Process, b. Accounting for Shipping and Handling Fees and Costs, c. Accounting for Consideration Given by a Vendor to a Customer, and d. Accounting for Gas-Balancing Arrangements. The adoption of ASU No. 2016-11 is not expected to have a material impact on the Company’s condensed consolidated financial statements. In May 2016, the FASB issued ASU No. 2016-12, Narrow-Scope Improvements and Practical Expedients ("ASU No. 2016-12"). ASU No. 2016-12 does not change the core principle of the guidance in ASC 606. Rather, this update affects only the narrow scope improvements to the guidance on collectability, noncash consideration, and completed contracts at transition. The effective date and transition requirements for ASU 2016-12 are the same as the effective date and transition requirements for ASC 606. The adoption of ASU No. 2016-12 is not expected to have a material impact on the Company’s condensed consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments ("ASU No. 2016-13"). Financial assets measured at amortized cost basis, including but not limited to loans, debt securities and trade receivables , that have the contractual right to receive cash are within the scope of this guidance. Under ASU No. 2016-13, these financial assets should be presented at the net amount expected to be collected. The income statement should reflect the measurement of credit losses that have taken place during the period. The amendments in ASU No. 2016-13 are effective for fiscal years beginning after December 15, 2019. Earlier adoption is permitted. The Company has decided not to early adopt ASU No. 2016-13. The adoption of ASU No. 2016-13 is not expected to have a material impact on the Company’s condensed consolidated financial statements.

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 (other than money-market funds, which are recorded on a reported net asset value basis disclosed below), accounts receivable, securities accounted for under ASC 323-10-25, accounts payable and accrued liabilities, deferred revenues, 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) June 30, 2016 Registered investment companies (1) $ 3,372 December 31, 2015 Registered investment companies (1) $ 3,576 ______________________ (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 long-term debt at fair value. The carrying value of the long-term debt represents amortized cost. The Company assesses the fair value of its long-term debt based on quoted market prices if available, and if not, an estimate of interest rates available to the Company for debt 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 the long-term debt as of June 30, 2016 and December 31, 2015 , respectively: 2016 2015 Fair Value Hierarchy Carrying Value Estimated Fair Value Carrying Value Estimated Fair Value Financial instrument not carried at fair value: Subordinated promissory note receivable Level 2 $ 83,078 $ 82,900 $ — $ — Long-term debt excluding capitalized Level 2 $ 2,275,767 $ 2,462,613 $ 2,274,144 $ 2,328,134

RII enhances the ability of the Company's Risk Assessment segment to serve the international insurance market. The allocations of the purchase price will be finalized once all information is obtained, but not to exceed one year from the acquisition date. 2015 Acquisitions On May 19, 2015, the Company acquired 100 percent of the stock of Wood Mackenzie Limited ("Wood Mackenzie") for a net cash purchase price of $2,889,629 , including $78,694 of an indemnity escrow, which the Company financed through a combination of debt and equity offerings, borrowings under the Company's credit facility, and cash on hand. Due to the fact that a portion of the purchase price was funded in pounds sterling and the remainder in U.S. dollars, the Company entered into a foreign currency hedging instrument to purchase pounds sterling. The Company recorded a gain on the hedge of $85,187 for the three and six months ended June 30, 2015 . The proceeds from the gain were utilized to partially fund the acquisition of Wood Mackenzie. Wood Mackenzie is a global provider of data analytics and commercial intelligence for the energy, chemicals, metals and mining verticals. This acquisition advances the Company’s strategy to expand internationally and positions the Company in the global energy market. Wood Mackenzie is included in the energy and specialized markets vertical, formerly named the specialized markets vertical, of the Decision Analytics segment. As of June 30, 2016 , the Company finalized the purchase accounting for the acquisition of Wood Mackenzie. The final purchase price allocations of the acquisition resulted in the following: Wood Mackenzie Cash and cash equivalents $ 35,398 Accounts receivable 80,307 Current assets 97,397 Fixed assets 71,929 Intangible assets 1,111,950 Goodwill and other 2,002,418 Other assets 1,993 Total assets acquired 3,401,392 Current liabilities 121,996 Deferred revenues 142,457 Deferred income taxes, net 204,289 Other liabilities 7,623 Total liabilities assumed 476,365 Net assets acquired 2,925,027 Cash acquired (35,398 ) Net cash purchase price $ 2,889,629 The impact of finalization of the purchase accounting for Wood Mackenzie was not material to the condensed consolidated statements of operations for the three and six months ended June 30, 2016 and 2015 . The Company determined the fair values of the assets and liabilities of Wood Mackenzie with the assistance of valuations performed by third party specialists, discounted cash flow analysis and estimates made by management. The final amounts assigned to intangible assets by type for the Wood Mackenzie acquisition are summarized in the table below: Weighted Average Useful Life Total Technology-related 7 years $ 104,663 Marketing-related 20 years 232,935 Customer-related 15 years 278,106 Database-related 20 years 496,246 Total intangible assets $ 1,111,950 Supplemental information on an unaudited pro forma basis is presented below as if the acquisition of Wood Mackenzie occurred at the beginning of 2015 . The pro forma information for the three and six months ended June 30, 2015 presented below is based on estimates and assumptions, which the Company believes to be reasonable but not necessarily indicative of the condensed consolidated financial position or results of operations in future periods or the results that actually would have been realized had this acquisition been completed at the beginning of 2015 . The unaudited pro forma information includes intangible asset amortization charges and incremental borrowing costs as a result of the acquisition, net of related tax, estimated using the Company’s effective tax rate for continuing operations for the three and six months ended June 30, 2015 : Three Months Ended Six Months Ended (unaudited) Pro forma revenues $ 477,561 $ 952,606 Pro forma income from continuing operations $ 140,378 $ 255,129 Pro forma basic income from continuing operations per share $ 0.86 $ 1.58 Pro forma diluted income from continuing operations per share $ 0.84 $ 1.55 On November 6, 2015, the Company acquired 100 percent of the stock of Infield Systems Limited ("Infield"). Infield is a provider of business intelligence, analysis, and research to the oil, gas, and associated marine industries. Infield has become part of Wood Mackenzie and continues to provide services to enhance Wood Mackenzie's upstream and supply chain capabilities in the Decision Analytics segment. The Company paid a net cash purchase price of $13,804 . On November 20, 2015, the Company acquired 100 percent of the stock of The PCI Group ("PCI"). PCI is a consortium of five specialist companies that offer integrated data and subscriptions research in the chemicals, fibers, films, and plastics sectors. PCI has become part of Wood Mackenzie and continues to provide services to enhance Wood Mackenzie's chemicals capabilities in the Decision Analytics segment. The Company paid a net cash purchase price of $37,387 . The preliminary allocations of the purchase prices for the acquisitions of Infield and PCI are subject to revisions as additional information is obtained about the facts and circumstances that existed as of the acquisition dates. The revisions may have a significant impact on the condensed consolidated financial statements. The allocations of the purchase prices will be finalized once all information is obtained, but not to exceed one year from the acquisition dates. The primary areas of the purchase price allocations that are not yet finalized relate to fixed assets and operating leases, income and non-income taxes, deferred revenues, the valuation of intangible assets acquired, and residual goodwill. The goodwill associated with the stock purchases of Wood Mackenzie, Infield and PCI is not deductible for tax purposes. For the six months ended June 30, 2015 , the Company incurred transaction costs related to the Wood Mackenzie acquisition of $26,617 included within "Selling, general and administrative" expenses and $13,336 included within "Interest expense" in the accompanying condensed consolidated statements of operations. Acquisition Escrows Pursuant to the related acquisition agreements, the Company has funded various escrow accounts to satisfy pre-acquisition indemnity and tax claims arising subsequent to the acquisition date, as well as a portion of the contingent payments. At June 30, 2016 and December 31, 2015 , the current portion of the escrows amounted to $ 4,856 and $38,656 , and the noncurrent portion of the escrows amounted to $0 and $4,591 , respectively. The current and noncurrent portions of the escrows have been included in “Other current assets” and "Other assets" in the accompanying condensed consolidated balance sheets, respectively.

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 $719,374 of cash consideration after a working capital adjustment of $626 , a subordinated promissory note with a face value of $100,000 and an eight year maturity (the "Note"), and other contingent consideration (collectively, the "Sale"). The Company recognized income from the discontinued operation, net of tax, of $155,000 and $137,909 for the three and six months ended June 30, 2016 , respectively. Results of operations for the healthcare business are reported as a discontinued operation for the three and six months ended June 30, 2016 and for all prior periods presented. 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 June 30, 2016, the Company had a receivable of $83,078 outstanding under the Note. 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. The Company also received a 10.0% 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 June 30, 2016, the Company had an equity investment of $8,400 related to such interest accounted for in accordance with ASC 323-10-25.

Goodwill and Intangible Assets	Goodwill and Intangible Assets: The following is a summary of the change in goodwill from December 31, 2015 through June 30, 2016 , both in total and as allocated to the Company’s operating segments: Risk Assessment Decision Analytics Total Goodwill at December 31, 2015 (1) $ 55,555 $ 2,697,471 $ 2,753,026 Current year acquisition 4,639 — 4,639 Purchase accounting reclassification — 8,641 8,641 Foreign currency translation (66 ) (136,299 ) (136,365 ) Goodwill at June 30, 2016 (1) $ 60,128 $ 2,569,813 $ 2,629,941 ______________________ (1) The balances at December 31, 2015 are net of the reclassification of goodwill to noncurrent assets held-for-sale of $381,800 . Refer to Note 6. Discontinued Operations for further discussion. 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 June 30, 2016 Technology-based 7 years $ 318,501 $ (186,321 ) $ 132,180 Marketing-related 18 years 238,075 (42,932 ) 195,143 Contract-based 6 years 4,996 (4,996 ) — Customer-related 14 years 488,605 (113,093 ) 375,512 Database-related 20 years 425,488 (24,061 ) 401,427 Total intangible assets $ 1,475,665 $ (371,403 ) $ 1,104,262 December 31, 2015 Technology-based 7 years $ 327,767 $ (175,746 ) $ 152,021 Marketing-related 18 years 259,158 (37,798 ) 221,360 Contract-based 6 years 4,996 (4,996 ) — Customer-related 14 years 512,632 (96,549 ) 416,083 Database-related 20 years 470,367 (14,748 ) 455,619 Total intangible assets $ 1,574,920 $ (329,837 ) $ 1,245,083 Amortization expense related to intangible assets for the three months ended June 30, 2016 and 2015 was $23,806 and $22,904 , respectively.

The effective tax rate for the three and six months ended June 30, 2016 is higher than the June 30, 2015 effective tax rate primarily due to non-recurring tax benefits related to the Wood Mackenzie acquisition in 2015. 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.

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, 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 and six months ended June 30, 2016 and 2015 : Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Numerator used in basic and diluted EPS: Income from continuing operations $ 106,736 $ 158,917 $ 216,466 $ 255,290 Income from discontinued operations (Note 6) 155,000 4,403 137,909 6,716 Net income $ 261,736 $ 163,320 $ 354,375 $ 262,006 Denominator: Weighted average number of common shares used 168,296,318 164,141,804 168,375,034 161,114,861 Effect of dilutive shares: Potential common shares issuable from stock 2,922,464 3,444,296 2,974,799 3,418,795 Weighted average number of common shares 171,218,782 167,586,100 171,349,833 164,533,656 The potential shares of common stock that were excluded from diluted EPS were 2,757,489 and 1,784,103 for the three months ended June 30, 2016 and 2015 , and 2,215,987 and 892,981 for the six months ended June 30, 2016 and 2015 , respectively, because the effect of including these potential shares was anti-dilutive.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Equity Compensation Plans	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 June 30, 2016 , there were 8,678,784 shares of common stock reserved and available for future issuance under the 2013 Incentive Plan. Cash received from stock option exercises for the six months ended June 30, 2016 and 2015 was $16,326 and $18,103 , 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 six months ended June 30, 2016 is presented below. Grant Date Service Vesting Period Stock Options Restricted Stock Common Stock April 1, 2016 Four-year graded vesting 1,219,096 244,244 — April 1, 2016 Not applicable — — 567 April 4, 2016 Four-year graded vesting 2,212 415 — April 18, 2016 Four-year graded vesting 1,266 239 — April 25, 2016 Three-year graded vesting 3,344 946 — May 2, 2016 Four-year graded vesting 12,931 2,438 — May 3, 2016 Four-year graded vesting 3,379 632 — June 6, 2016 Four-year graded vesting 4,029 751 — 1,246,257 249,665 567 On July 1, 2016, the Company granted 2,471 shares of common stock, 26,417 nonqualified stock options that were immediately vested, 51,381 nonqualified stock options with a one -year service period, and 10,968 deferred stock units to the directors of the Company. The nonqualified stock options have an exercise price equal to the closing price of the Company’s common stock at the grant date and a ten -year contractual term. The fair value of the stock options granted for the six months ended June 30, 2016 and 2015 was estimated using a Black-Scholes valuation model that uses the weighted average assumptions noted in the following table: 2016 2015 Option pricing model Black-Scholes Black-Scholes Expected volatility 20.29 % 20.25 % Risk-free interest rate 1.15 % 1.51 % Expected term in years 4.5 4.6 Dividend yield — % — % Weighted average grant date fair value per stock option $ 15.33 $ 12.91 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 volatility factor for stock options granted in 2016 was based on the volatility of the Company's stock. 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, 2015 and June 30, 2016 and changes during the interim period are presented below: Number Weighted Aggregate Outstanding at December 31, 2015 9,117,733 $ 40.17 $ 334,691 Granted 1,246,257 $ 80.15 Exercised (655,448 ) $ 30.93 $ 30,973 Cancelled or expired (137,177 ) $ 71.53 Outstanding at June 30, 2016 9,571,365 $ 45.55 $ 340,039 Exercisable at June 30, 2016 6,765,200 $ 34.17 $ 317,357 Exercisable at December 31, 2015 6,541,229 $ 29.81 $ 307,924 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. In accordance with ASC 718, Stock Compensation ("ASC 718"), excess tax benefit from exercised stock options and restricted stock lapsed is recorded as an increase to additional paid-in capital and a corresponding reduction in income taxes payable. 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. The amount of the tax benefit that has been realized, as a result of those excess tax benefits, is presented as a financing cash inflow within the accompanying condensed consolidated statements of cash flows. For the six months ended June 30, 2016 and 2015 , the Company recorded excess tax benefits of $11,657 and $7,848 , respectively. The Company realized $6,570 and $8,419 of tax benefit within the Company’s quarterly tax payments through June 30, 2016 and 2015 , respectively. Stock based compensation expense for the six months ended June 30, 2016 and 2015 was $16,468 and $19,047 , 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, 2015 and June 30, 2016 and changes during the interim period are presented below: Number Weighted Average Grant Outstanding at December 31, 2015 533,768 $ 66.25 Granted 249,665 $ 80.15 Vested (212,123 ) $ 63.80 Forfeited (26,145 ) $ 71.24 Outstanding at June 30, 2016 545,165 $ 72.77 As of June 30, 2016 , there was $75,229 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 2.98 years. As of June 30, 2016 , there were 2,806,165 and 544,885 nonvested stock options and restricted stock, respectively, of which 2,353,193 and 457,990 are expected to vest. The total grant date fair value of options vested during the six months ended June 30, 2016 and 2015 was $6,807 and $10,191 , respectively. The total grant date fair value of restricted stock vested during the six months ended June 30, 2016 and 2015 was $6,889 and $9,727 , respectively. 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 six months ended June 30, 2016 and 2015 , the Company issued 16,390 and 11,404 shares of common stock at a weighted discounted price of $76.41 and $68.51 for the ESPP, respectively.

Compensation and Retirement Disclosure [Abstract]
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 and six months ended June 30, are summarized below: Pension Plan and SERP Postretirement Plan For the Three Months Ended June 30, 2016 2015 2016 2015 Interest cost $ 4,781 $ 4,487 $ 120 $ 134 Expected return on plan assets (7,952 ) (8,657 ) (124 ) (142 ) Amortization of prior service credit — — (36 ) (38 ) Amortization of net actuarial loss 794 612 125 156 Net periodic (benefit) cost $ (2,377 ) $ (3,558 ) $ 85 $ 110 Employer contributions, net $ 218 $ 278 $ 144 $ 139 For the Six Months Ended June 30, 2016 2015 2016 2015 Interest cost $ 9,562 $ 9,044 $ 240 $ 268 Expected return on plan assets (15,904 ) (17,216 ) (248 ) (285 ) Amortization of prior service credit — — (72 ) (75 ) Amortization of net actuarial loss 1,588 1,407 250 312 Net periodic (benefit) cost $ (4,754 ) $ (6,765 ) $ 170 $ 220 Employer contributions, net $ 543 $ 495 $ 105 $ 91 The expected contributions to the Pension Plan, SERP and Postretirement Plan for the year ending December 31, 2016 are consistent with the amounts previously disclosed as of December 31, 2015 .

Segment Reporting

Segment Reporting	6 Months Ended

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, financial services, and energy and specialized markets. 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 and six months ended June 30, 2016 and 2015 . Refer to Note 6 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. On a geographic basis, revenues from countries outside of the U.S. accounted for 22.3% and 12.7% of the Company's consolidated revenues for the six months ended June 30, 2016 and 2015 , respectively. No individual country outside of the U.S. accounted for 5.0% or more of the Company's consolidated revenues for the six months ended June 30, 2016 or 2015 . The following table provides the Company’s revenue and EBITDA by reportable segment for the three and six months ended June 30, 2016 and 2015 , and the reconciliation of EBITDA to operating income as shown in the accompanying condensed consolidated statements of operations: For the Three Months Ended For the Three Months Ended June 30, 2016 June 30, 2015 Decision Risk Total Decision Risk Total Revenues $ 317,179 $ 181,117 $ 498,296 $ 256,869 $ 171,730 $ 428,599 Expenses: Cost of revenues (exclusive of items (123,443 ) (55,023 ) (178,466 ) (104,225 ) (50,414 ) (154,639 ) Selling, general and administrative (54,005 ) (21,552 ) (75,557 ) (62,442 ) (19,894 ) (82,336 ) Investment income and others, net 880 (34 ) 846 (380 ) 121 (259 ) Gain on derivative instruments — — — 85,187 — 85,187 EBITDA from discontinued operations 254,814 — 254,814 19,576 — 19,576 EBITDA 395,425 104,508 499,933 194,585 101,543 296,128 Depreciation and amortization of fixed (22,492 ) (6,896 ) (29,388 ) (16,326 ) (6,351 ) (22,677 ) Amortization of intangible assets (23,647 ) (159 ) (23,806 ) (22,815 ) (89 ) (22,904 ) Less: Investment income and others, net (880 ) 34 (846 ) 380 (121 ) 259 Gain on derivative instruments — — — (85,187 ) — (85,187 ) EBITDA from discontinued (254,814 ) — (254,814 ) (19,576 ) — (19,576 ) Operating income $ 93,592 $ 97,487 191,079 $ 51,061 $ 94,982 146,043 Investment income and others, net 846 (259 ) Gain on derivative instruments — 85,187 Interest expense (31,435 ) (37,662 ) Income from continuing operations $ 160,490 $ 193,309 For the Six Months Ended For the Six Months Ended June 30, 2016 June 30, 2015 Decision Risk Total Decision Risk Total Revenues $ 630,124 $ 360,873 $ 990,997 $ 470,220 $ 342,672 $ 812,892 Expenses: Cost of revenues (exclusive of items (245,032 ) (106,711 ) (351,743 ) (187,037 ) (101,386 ) (288,423 ) Selling, general and administrative (106,389 ) (40,205 ) (146,594 ) (93,087 ) (38,963 ) (132,050 ) Investment income and others, net 992 (102 ) 890 (949 ) 188 (761 ) Gain on derivative instruments — — — 85,187 — 85,187 EBITDA from discontinued operations 269,485 — 269,485 35,620 — 35,620 EBITDA 549,180 213,855 763,035 309,954 202,511 512,465 Depreciation and amortization of fixed (47,393 ) (13,882 ) (61,275 ) (29,752 ) (12,313 ) (42,065 ) Amortization of intangible assets (47,430 ) (247 ) (47,677 ) (30,182 ) (177 ) (30,359 ) Less: Investment income and others, net (992 ) 102 (890 ) 949 (188 ) 761 Gain on derivative instruments — — — (85,187 ) — (85,187 ) EBITDA from discontinued (269,485 ) — (269,485 ) (35,620 ) — (35,620 ) Operating income $ 183,880 $ 199,828 383,708 $ 130,162 $ 189,833 319,995 Investment income and others, net 890 (761 ) Gain on derivative instruments — 85,187 Interest expense (63,467 ) (55,924 ) Income from continuing operations $ 321,131 $ 348,497 Operating segment revenues by type of service is provided below: For the Three Months Ended June 30, For the Six Months Ended June 30, 2016 2015 2016 2015 Decision Analytics: Insurance $ 175,476 $ 165,276 $ 347,021 $ 319,009 Financial services 30,585 26,380 59,059 61,550 Energy and specialized markets 111,118 65,213 224,044 89,661 Total Decision Analytics 317,179 256,869 630,124 470,220 Risk Assessment: Industry-standard insurance programs 138,599 130,776 276,026 261,372 Property-specific rating and underwriting information 42,518 40,954 84,847 81,300 Total Risk Assessment 181,117 171,730 360,873 342,672 Total revenues $ 498,296 $ 428,599 $ 990,997 $ 812,892 Long-lived assets by country are provided below: June 30, 2016 December 31, 2015 Long-lived assets: United States of America $ 1,590,865 $ 2,178,142 United Kingdom 2,345,761 2,799,392 Other countries 276,147 11,549 Total long-lived assets $ 4,212,773 $ 4,989,083

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. At this time, it is not possible to determine the ultimate resolution of, or estimate the liability related to this matter. On February 1, 2016, the Company was served with a nationwide putative class action complaint filed in the United States District Court for the Eastern District of North Carolina naming Intellicorp. The complaint titled Frank DiSalvo v. Intellicorp Records, Inc. claims violations of the FCRA and alleges a section 1681b(b)(1) claim on behalf of all individuals residing in the United States who were the subjects of consumer reports furnished by Intellicorp for employment purposes within the period prescribed by the FCRA, 15 U.S.C. Section 1681p without first obtaining from the user of the report a certification that such user had complied with the obligations under Section 1681b(b)(2) as to the subject of the consumer report. The class complaint alleges that Intellicorp violated the FCRA section 1681b(b)(1) by failing to obtain the required specific certification from its customers to whom Intellicorp furnished consumer reports as to each consumer report provided before providing the specific consumer report that was the subject of the certification. The complaint alleges that the violations were willful or in the alternative negligent and seeks statutory damages for the class 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 18, 2016, the parties filed a joint motion to stay all proceedings pending the resolution of the United States Supreme Court’s decision in Spokeo v. Robins, No. 13-1339. After Spokeo was decided on May 16, 2016, plaintiffs voluntarily dismissed their federal court complaint and filed a virtually identical complaint in Ohio State court on May 27, 2016. Defendants removed that complaint to the United States District Court for the Northern District of Ohio on July 1, 2016. At this time, it is not possible to determine the ultimate resolution of, or estimate the liability related to this matter. 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 (“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. At this time, it is not possible to determine the ultimate resolution of, or estimate the liability related to this matter. Insurance Services Office, Inc. Litigation 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 20, 2016. At this time, it is not possible to determine the ultimate resolution of, or estimate the liability related to this matter. On February 19, 2016, the Company was served with a notice of a summons and complaint filed on January 29, 2016 against ISO 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 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 their first amended complaint asserting federal jurisdiction under the Class Action Fairness Act, adding a number of insurer defendants and amending their damages claim to include punitive damages. After defendants indicated that they would be filing motions to dismiss the first amended complaint at a Rule 16 Conference on April 12, 2016, the Court gave plaintiffs until May 6, 2016 to move for leave to file a second amended complaint. On May 6, 2016, plaintiffs filed a Motion to amend the first amended complaint with a proposed second amended complaint, which did not name ISO or the Company as a defendant. No opposition was filed to the motion to amend, which remains pending. At this time, it is not possible to determine the ultimate resolution of, or estimate the liability related to this matter.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events: On July 26, 2016, the Company completed the acquisition of Greentech Media, Inc. (“Greentech Media”), an information services provider for the electricity and renewables sector, for a net cash purchase price of $37,000 , which was funded from the general assets of the Company. The Company used $4,400 of the net cash purchase price to fund the indemnity escrows. The cash paid will be adjusted subsequent to close to reflect final balances of certain working capital accounts and other closing adjustments. Greentech Media will become part of Wood Mackenzie within the Decision Analytics segment and enables Wood Mackenzie to provide its clients with market intelligence across several categories, including solar generation, energy storage, and smart grids that react to changes in supply and demand. Due to the limited time since the acquisition date and limitations on access to Greentech information prior to the acquisition date, the initial accounting for the business combination is incomplete at this time. As a result, the Company is unable to provide amounts recognized as of the acquisition date for major classes of assets and liabilities acquired and resulting from the transaction, including the information required for contingencies, intangible assets and goodwill. This information is expected to be included in the quarterly report on Form 10-Q for the nine months ending September 30, 2016.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In April 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-03. The amendments in this update require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The Company adopted the guidance on January 1, 2016 and as a result, debt issuance costs of $22,275 were reclassified from "Other assets" to "Long-term debt" on the Company's condensed consolidated balance sheet as of December 31, 2015. In April 2015, the FASB issued ASU No. 2015-05, Customer's Accounting for Fees Paid in a Cloud Computing Arrangement ("ASU No. 2015-05"). This guidance is intended to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement, primarily to determine whether the arrangement includes a sale or license of software. The Company adopted the guidance on January 1, 2016. The adoption of ASU No. 2015-05 did not have a material impact on the Company's condensed consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments ("ASU No. 2015-16"). ASU No. 2015-16 requires, for business combinations, that the acquirer record, in the same period's financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The Company adopted the guidance on January 1, 2016. Adoption of this guidance did not have a material impact on the results of operations or financial position (see Note 5). In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU No. 2016-01”). The amendments in this update require all equity investments to be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under equity method of accounting or those that result in consolidation of the investee). The amendments allow equity investments that do not have readily determinable fair values to be remeasured at fair value either upon occurrence of an observable price change or upon identification of an impairment. The amendments in ASU No. 2016-01 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. For amendments applicable to the Company, early adoption is not permitted. The Company will conform to ASC No. 2016-01 in the condensed consolidated financial statements in future periods. In February 2016, the FASB issued ASU No. 2016-02, Leases ("ASU No. 2016-02"). This ASU amends the existing accounting considerations and treatments for leases through the creation of Topic 842, Leases , to increase transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet and disclosing key information about lease arrangements. The amendments in ASU No. 2016-02 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application of the amendments is permitted for all entities. The Company has decided not to early adopt ASU No. 2016-02 and is currently evaluating the impact the amendments may have on its condensed consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-07, Equity Method and Joint Ventures (“ASU No. 2016-07”). The amendments in the update eliminate the requirement that an entity retroactively adopt the equity method of accounting if an investment qualifies for use of the equity method as a result of an increase in the level of ownership or degree of influence. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of account as of the date the investment becomes qualified for equity method accounting. The amendments in ASU No. 2016-07 are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The Company has not elected to early adopt. The adoption of ASU No. 2016-07 is not expected to have a material impact on the Company’s condensed consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-08, Principal Versus Agent Considerations (“ASU No. 2016-08”). The amendments to this update are intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations. The amendments in ASU No. 2016-08 are effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is currently evaluating ASU No. 2016-08 and has not determined the impact this standard may have on its financial statements nor decided upon the method of adoption. 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 amendments in ASU No. 2016-09 are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any entity in any interim or annual period. The Company has not elected to early adopt. The Company is currently evaluating ASU No. 2016-09 and has not determined the impact this amendment may have on its financial statements. In April 2016, the FASB issued ASU No. 2016-10, Identifying Performance Obligations and Licensing (“ASU No. 2016-10”). The amendments in this update clarify the following two aspects of Accounting Standards Codification ("ASC") 606 ("ASC 606"), Revenue From Contracts With Customers : identifying performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. The amendments in ASU No. 2016-10 are effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is currently evaluating ASU No. 2016-10 and has not determined the impact this standard may have on its financial statements nor decided upon the method of adoption. In May 2016, the FASB issued ASU No. 2016-11, Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-16 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting (SEC Update) ("ASU No. 2016-11"). Specifically, registrants should not rely on the following SEC Staff Observer comments upon adoption of ASC 606: a. Revenue and Expense Recognition for Freight Services in Process, b. Accounting for Shipping and Handling Fees and Costs, c. Accounting for Consideration Given by a Vendor to a Customer, and d. Accounting for Gas-Balancing Arrangements. The adoption of ASU No. 2016-11 is not expected to have a material impact on the Company’s condensed consolidated financial statements. In May 2016, the FASB issued ASU No. 2016-12, Narrow-Scope Improvements and Practical Expedients ("ASU No. 2016-12"). ASU No. 2016-12 does not change the core principle of the guidance in ASC 606. Rather, this update affects only the narrow scope improvements to the guidance on collectability, noncash consideration, and completed contracts at transition. The effective date and transition requirements for ASU 2016-12 are the same as the effective date and transition requirements for ASC 606. The adoption of ASU No. 2016-12 is not expected to have a material impact on the Company’s condensed consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments ("ASU No. 2016-13"). Financial assets measured at amortized cost basis, including but not limited to loans, debt securities and trade receivables , that have the contractual right to receive cash are within the scope of this guidance. Under ASU No. 2016-13, these financial assets should be presented at the net amount expected to be collected. The income statement should reflect the measurement of credit losses that have taken place during the period. The amendments in ASU No. 2016-13 are effective for fiscal years beginning after December 15, 2019. Earlier adoption is permitted. The Company has decided not to early adopt ASU No. 2016-13. The adoption of ASU No. 2016-13 is not expected to have a material impact on the Company’s condensed consolidated financial statements.
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 June 30, 2016 and December 31, 2015 , the Company had no 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 2015 Form 10-K filing.
