Accounting Policies [Abstract]

Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation and Summary of Significant Accounting Policies:

The accompanying consolidated financial statements have been prepared on the basis of accounting principles generally accepted in the United States of America (“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, 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 equity awards granted, and assets and liabilities for pension and postretirement benefits. Actual results may ultimately differ from those estimates. Effective the first quarter of 2018, the operating segments of the Company are Insurance, Energy and Specialized Markets, and Financial Services. Previously, its operating segments were Decision Analytics and Risk Assessment. (See Note 19.). Certain reclassifications, including reflecting acquisition-related liabilities as a separate line item in 2019, have been made within the consolidated balance sheets, consolidated statements of cash flows and in the notes to conform to the respective 2019 presentation.

Significant accounting policies include the following:

(a) Intercompany Accounts and Transactions

The consolidated financial statements include the accounts of Verisk. All intercompany accounts and transactions have been eliminated.

(b) Revenue Recognition

The following describes the Company’s primary types of revenues and the applicable revenue recognition policies. The Company recognizes revenues through recurring and non-recurring long-term agreements (generally one to five years) for hosted subscriptions, advisory/consulting services, and for transactional solutions. Each of our reportable segments, Insurance, Energy and Specialized Markets, and Financial Services, has a portion of its revenue from more than one of these revenue types. The Company’s revenues are primarily derived from the sale of services where revenue is recognized when control of the promised services is transferred to customers in an amount that reflects the consideration that the Company expects to be entitled to in exchange for those services. Fees for services provided by the Company are non-refundable. Revenue is recognized net of applicable sales tax withholdings.

Hosted Subscriptions

The Company offers two forms of hosted subscriptions. The first and most prevalent form of hosted subscription is where customers access content only through the online portal (the "Hosted Subscription"). The Company grants a license to the customer to enter the online portal. The license is a contractual mechanism that allows the customer to access the online portal for a defined period of time. As the license alone does not provide utility to the customer, the customer has no contractual right to take possession of the online portal at any time, and the customer cannot engage another party to host the online portal and related content, it is not considered a functional license under Topic 606. The Company's promise to the customer is to provide continuous access to the online portal and to update the content throughout the subscription period. Hosted Subscription is a single performance obligation that represents a series of distinct services (daily access to the online portal and related content) that are substantially the same and that have the same pattern of transfer to the customer. The Company recognizes revenue for Hosted Subscriptions ratably over the subscription period on a straight-line basis as services are performed and continuous access to information in the online portal is provided over the entire term of the agreements.

The second form of hosted subscription is where customers have access to the Company's online portals combined with software content that is delivered via disk drive/download to the customer (“Hosted Subscription with Disk Drive/Download”) and is offered only on a limited basis. For this form of hosted subscription, the Company also grants the customer a license to enter the online portal as well as access the software content as needed and acts as the same contractual mechanism as described for Hosted Subscriptions. The Hosted Subscription with Disk Drive/Download works in such a manner that the customer gains significant benefit, functionality and overall utility only when the online portal and the software content are used together. The disk drive/download contains the models while the online portal contains the latest data and research which is updated throughout the subscription period. The models within the disk drive/download depend on the data and research contained within the online portal. The data and research within the online portal is only useful when the customer can utilize it within the models (e.g., queries, projections, etc.) so that they may use the most current information and alerts to forecast potential future losses. The software content is only sold together with the online portal to provide a highly interdependent and interrelated promise and therefore represents a single performance obligation. As the customer has no contractual right to take possession of the online portal at any time, and the customer cannot engage another party to host the online portal and related software content, it is not considered a functional license under Topic 606. The Company's promise to the customer is to deliver the disk drive/download, to provide continuous access to the online portal, and to update the software content throughout the subscription period. The Company recognizes revenue for Hosted Subscriptions with Disk Drive/Download ratably over the subscription period on a straight-line basis as services are performed and continuous access to information is provided over the entire term of the agreements.

Subscriptions are generally paid in advance of rendering services either quarterly or annually upon commencement of the subscription period, which is usually for one year and in most instances automatically renewed each year.

Advisory/Consulting Services

The Company provides certain discrete project based advisory/consulting services, which are recognized over time by measuring the progress toward complete satisfaction of the performance obligation, based on the input method of consulting hours worked; this aligns with the results achieved and value transferred to the customer. The hours consumed are most reflective of the measure of progress towards satisfying the performance obligation, as the resources hours worked directly tie to the progress of the services to be provided. In general, they are billed over the course of the project.

Transactional Solutions

Certain solutions are also paid for by customers on a transactional basis. The Company recognizes these revenues as the solutions are delivered or services performed at a point in time. In general, the customers are billed monthly at the end of each month.

(c) Deferred Revenues

The Company invoices its customers in annual, quarterly, monthly, or milestone installments. Amounts billed and/or collected in advance of services being provided are recorded as “Deferred revenues” and “Other noncurrent liabilities” in the accompanying consolidated balance sheets and are recognized as the services are performed, control is transferred to customers, and the applicable revenue recognition criteria is met.

(d) Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are generally recorded at the invoiced amount. The allowance for doubtful accounts is estimated based on an analysis of the aging of the accounts receivable, historical write-offs, customer payment patterns, individual customer credit worthiness, current economic trends, and/or establishment of specific reserves for customers in adverse financial condition. The Company assesses the adequacy of the allowance for doubtful accounts on a quarterly basis.

(e) Deferred Commissions

The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if it expects the benefit of those costs to be longer than one year. The Company has determined that certain sales incentive programs meet the requirements to be capitalized. The incremental costs of obtaining a contract with a customer, which primarily consist of sales commissions, are deferred and amortized over a useful life of five years that is consistent with the transfer to the customer the services to which the asset relates. The Company classifies deferred commissions as current or noncurrent based on the timing of expense recognition. The current and noncurrent portions of deferred commissions are included in prepaid expenses and other assets, respectively, in the consolidated balance sheets as of December 31, 2019. Amortization expense related to deferred commissions is computed on a straight-line basis over its estimated useful lives and included in "Selling, general and administrative" within the accompanying consolidated statements of operations.

(f) Fixed Assets and Finite-lived Intangible Assets

Fixed assets and finite-lived intangibles are stated at cost less accumulated depreciation and amortization, which are computed on a straight-line basis over their estimated useful lives. Leasehold improvements are amortized over the shorter of the useful life of the asset or the lease term.

The Company’s internal software development costs primarily relate to internal-use software. Such costs are capitalized in the application development stage in accordance with ASC 350-40, Internal-use Software ("ASC 350-40"). The Company also capitalizes software development costs upon the establishment of technological feasibility for a product in accordance with ASC 985-20, Software to be Sold, Leased, or Marketed (“ASC 985-20”). Software development costs are amortized on a straight-line basis.

In accordance with ASC 360, Property, Plant & Equipment, whenever events or changes in circumstances indicate that the carrying amount of long-lived assets and finite-lived intangible assets may not be recoverable, the Company reviews its long-lived assets and finite-lived intangible assets for impairment by first comparing the carrying value of the assets to the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the assets. If the carrying value exceeds the sum of the assets’ undiscounted cash flows, the Company estimates and recognizes an impairment loss by taking the difference between the carrying value and fair value of the assets.

(g) Leases

The Company has operating and finance leases for corporate offices, data centers, and certain equipment that are accounted for under ASC 842. The leases have remaining lease terms ranging from one year to fourteen years, some of which include the options to extend the leases for up to twenty years, and some of which include the options to terminate the leases within one year. Extension and termination options are considered in the calculation of the right-of-use (“ROU”) assets and lease liabilities when the Company determines it is reasonably certain that it will exercise those options.

The Company determines if an arrangement is a lease at inception. The Company considers any contract where there is an identified asset and that it has the right to control the use of such asset in determining whether the contract contains a lease. A ROU asset represents the Company’s right to use an underlying asset for the lease term and the lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease ROU assets

and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s operating leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available on the adoption date in determining the present value of lease payments. The incremental borrowing rate was calculated by using the Company's credit rating on its publicly-traded U.S. unsecured bonds and estimating an appropriate credit rating for similar secured debt instruments. The Company's calculated credit rating on secured debt instruments determined the yield curve used. The Company calculated an implied spread and applied the spreads to the risk-free interest rates based on the yield of the U.S. Treasury zero coupon securities with a maturity equal to the remaining lease term in determining the borrowing rates for all operating leases. The operating lease ROU assets include any lease payments made prior to the rent commencement date and exclude lease incentives. Lease expense for lease payments are recognized on a straight-line basis over the lease term. Operating lease transactions are included in "Operating lease right-of-use assets, net", and "Operating lease liabilities", current and noncurrent, within the accompanying consolidated balance sheets. Finance leases are included in property and equipment under "Fixed assets, net", "Short-term debt and current portion of long-term debt", and "Long-term debt" within the accompanying consolidated balance sheets.

(h) Fair Value of Financial and Non-financial Instruments

The Company follows the provisions of ASC 820-10, Fair Value Measurements (“ASC 820-10”), which defines fair value, establishes a framework for measuring fair value under U.S. GAAP and expands fair value measurement disclosures. The Company follows the provisions of ASC 820-10 for its financial assets and liabilities recognized or disclosed at fair value on a recurring basis. The Company follows the provisions of ASC 820-10 for its non-financial assets and liabilities recognized or disclosed at fair value.

(i) Foreign Currency

The Company has determined local currencies are the functional currencies of the foreign operations. The assets and liabilities of foreign subsidiaries are translated at the period-end rate of exchange and statement of operations items are translated at the average rates prevailing during the year. The resulting translation adjustment is recorded as a component of “Accumulated other comprehensive losses” in the accompanying consolidated statements of changes in stockholders’ equity.

(j) Stock Based Compensation

The Company follows ASC 718, Stock Compensation (“ASC 718”). Under ASC 718, stock based compensation cost is measured at the grant date, based on the fair value of the awards granted, and is recognized as expense over the requisite service period.

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 expected term for the stock options granted for a majority of the awards 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 the Company's historical daily closing prices over the most recent period that is commensurate with the expected term of the stock option awards. The expected dividend yield was based on the Company’s expected annual dividend rate on the date of grant.

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. Restricted stock generally has a service vesting period of four years and the Company recognizes the expense ratably over this service vesting period.

Performance share units (“PSU”) vest at the end of a three-year performance period, subject to the recipient’s continued service. Each PSU represents the right to receive one share of Verisk common stock and the ultimate realization is based on the Company’s achievement of certain market performance criteria. The Company determined the grant date fair value of PSUs with the assistance of a third-party valuation specialist and based on estimates provided by the Company. The valuation of the PSUs employed the Monte Carlo simulation model, which includes certain key assumptions that were applied to the Company and its peer group. Those key assumptions included valuation date stock price, expected volatility, correlation coefficients, risk-free rate of return, and expected dividend yield. The valuation date stock price is based on the dividend-adjusted closing price on the grant date. Expected

volatility is calculated using historical daily closing prices over a period that is commensurate with the length of the performance period. The correlation coefficients are based on the price data used to calculate the historical volatilities. The risk-free rate of return is based on the yield of U.S. Treasury zero coupon securities with a maturity equal to the length of the performance period. The expected dividend yield was based on the Company and its peer group’s expected dividend rate over the performance period.

The Company estimates expected forfeitures of equity awards at the date of grant and recognizes compensation expense only for those awards expected to vest. The forfeiture assumption is ultimately adjusted to the actual forfeiture rate. Estimated forfeiture is ultimately adjusted to actual forfeiture. Changes in the forfeiture assumptions may impact the total amount of expense ultimately recognized, as well as the timing of expense recognized over the requisite service period.

Excess tax benefit from exercised stock options, lapsing of restricted stock and PSUs is recorded as an income tax benefit in the accompanying consolidated statements of operations. This tax benefit is calculated as the excess of the intrinsic value of options exercised and of the market value of restricted stock lapsed over the compensation recognized for financial reporting purposes.

(k) Research and Development Costs

Research and development costs, which are primarily related to personnel and related overhead costs incurred in developing new services for customers, are expensed as incurred. Such costs were $65.6 million, $47.6 million and $37.4 million for the years ended December 31, 2019, 2018 and 2017, respectively, and were included in the accompanying consolidated statements of operations.

(l) Advertising Costs

Advertising costs, which are primarily associated with promoting the Company’s brand, names and solutions provided, are expensed as incurred. Such costs were $10.7 million, $9.0 million and $6.9 million for the years ended December 31, 2019, 2018 and 2017, respectively.

(m) Income Taxes

The Company accounts for income taxes under the asset and liability method under ASC 740, Income Taxes (“ASC 740”), which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.

Deferred tax assets are recorded to the extent these assets are more likely than not to be realized. In making such determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies, and recent financial operations. Valuation allowances are recognized to reduce deferred tax assets if it is determined to be more likely than not that all or some of the potential deferred tax assets will not be realized.

The Company follows ASC 740-10, Income Taxes (“ASC 740-10”), which clarifies the accounting for uncertainty in income taxes recognized in the financial statements. ASC 740-10 provides that a tax benefit from an uncertain tax position may be recognized based on the technical merits when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes. Income tax positions must meet a more likely than not recognition threshold in accordance with ASC 740-10. This standard also provides guidance on measurement, derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition.

The Company recognizes interest and penalties related to unrecognized tax benefits within the income tax expense line in the accompanying consolidated statements of operations. Accrued interest and penalties are included within “Other liabilities” on the accompanying consolidated balance sheets.

(n) Earnings Per Share

Basic and diluted earnings per share (“EPS”) are determined in accordance with ASC 260, Earnings per Share, which specifies the computation, presentation and disclosure requirements for EPS. Basic EPS excludes all dilutive common stock equivalents. It is based upon the weighted average number of common shares outstanding during the period. Diluted EPS, as calculated using the treasury stock method, reflects the potential dilution that would occur if the Company’s dilutive outstanding stock options and stock awards were issued.

(o) Pension and Postretirement Benefits

The Company accounts for its pension and postretirement benefits under ASC 715, Compensation — Retirement Benefits (“ASC 715”). ASC 715 requires the recognition of the funded status of a benefit plan in the balance sheet, the recognition in other comprehensive income (loss) of gains or losses and prior service costs arising during the period, but which are not included as components of periodic benefit cost or credit, and the measurement of defined benefit plan assets and obligations as of the balance sheet date. The Company utilizes a valuation date of December 31.

(p) Product Warranty Obligations

The Company provides warranty coverage for certain of its solutions. The Company recognizes a product warranty obligation when claims are probable and can be reasonably estimated. As of December 31, 2019 and 2018, product warranty obligations were not material.

In the ordinary course of business, the Company enters into numerous agreements that contain standard indemnities whereby the Company indemnifies another party for breaches of confidentiality, infringement of intellectual property or gross negligence. Such indemnifications are primarily granted under licensing of computer software. Most agreements contain provisions to limit the maximum potential amount of future payments that the Company could be required to make under these indemnifications; however, the Company is not able to develop an estimate of the maximum potential amount of future payments to be made under these indemnifications as the triggering events are not subject to predictability.

(q) Loss Contingencies

The Company accrues for costs relating to litigation, claims and other contingent matters when such liabilities become probable and reasonably estimable. Such estimates are based on management’s judgment. Actual amounts paid may differ from amounts estimated, and such differences will be charged to operations in the period in which the final determination of the liability is made.

(r) Goodwill

Goodwill represents the excess of acquisition costs over the fair value of tangible net assets and identifiable intangible assets of the businesses acquired. Goodwill and intangible assets deemed to have indefinite lives are not amortized. Intangible assets determined to have finite lives are amortized over their useful lives. 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. The Company completed the required annual impairment test as of June 30, 2019, which resulted in no impairment of goodwill in 2019. This test 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 the goodwill.

Risks and Uncertainties [Abstract]
Concentration of Credit Risk	Concentration of Credit Risk: Financial instruments that potentially expose the Company to credit risk consist primarily of cash and cash equivalents as well as accounts receivable, net which are generally not collateralized. The Company maintains its cash and cash equivalents in higher credit quality financial institutions in order to limit the amount of credit exposure. The total domestic cash balances are insured by the Federal Deposit Insurance Corporation (“FDIC”) to a maximum amount of $250.0 thousand per bank as of December 31, 2019 and 2018. As of December 31, 2019 and 2018, the Company had cash balances on deposit with ten and eight banks that exceeded the balance insured by the FDIC limit by approximately $36.4 million and $16.8 million, respectively. As of December 31, 2019 and 2018, the Company also had cash on deposit with foreign banks of approximately $145.7 million and $121.1 million, respectively. The Company considers the concentration of credit risk associated with its accounts receivable to be commercially reasonable and believes that such concentration does not result in the significant risk of near-term severe adverse impacts. The Company’s top fifty customers represent approximately 33% of revenues for 2019 and 34% for 2018 as well as for 2017, respectively, with no individual customer accounting for more than approximately 3% of revenues for the years ended December 31, 2019, 2018, and 2017. No individual customer comprised more than approximately 3% of accounts receivable as of December 31, 2019 and 2018.

Revenue from Contract with Customer [Abstract]

Revenues

Revenues:

In May 2014, the FASB issued Topic 606, which replaces numerous requirements under Topic 605, Revenue Recognition ("Topic 605"), in U.S. GAAP, including industry-specific requirements, and provides companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. Revenue is recognized in a five-step model: 1) identify the contract with a customer; 2) identify the performance obligations in the contract; 3) determine the transaction price; 4) allocate the transaction price to the performance obligations in the contract; and 5) recognize revenue when or as the company satisfies a performance obligation. Effective January 1, 2018, the Company

adopted the requirements of Topic 606 using the modified retrospective method in which case the cumulative effect of applying the standard would be recognized at the date of initial application. The results of operations for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with the historic accounting under Topic 605. The accounting policies related to Topic 605 were presented in the Form 10-K for the year ended December 31, 2017, for which the Company recognized revenue when the following four criteria were met: persuasive evidence of an arrangement existed, delivery had occurred or services had been rendered, fees and/or price was fixed or determinable, and collectability was reasonably assured.

In accordance with Topic 606, the disclosure of the impact of adoption on the accompanying consolidated statement of operations and the accompanying consolidated balance sheet for and as of the year ended December 31, 2018 are as follows:



	For the year ended December 31, 2018 under Topic 605			Adjustments due to ASU 2014-09			For the year ended December 31, 2018 under Topic 606

Contract assets are defined as an entity's right to consideration in exchange for goods or services that the entity has transferred to a customer when that right is conditioned on something other than the passage of time. As of December 31, 2019 and 2018, the Company had no contract assets.

Contract liabilities are defined as an entity's obligation to transfer goods or services to a customer for which the entity has received consideration (an amount of consideration is due) from the customer. As of December 31, 2019 and 2018, the Company had contract liabilities that primarily related to unsatisfied performance obligations to provide customers with the right to use and update the online content over the remaining contract term of $443.2 million and $385.1 million, respectively. The $58.1 million increase in contract liabilities from December 31, 2018 to December 31, 2019 was primarily due to billings of $357.8 million that were paid in advance, partially offset by $299.7 million of revenue recognized for the year ended December 31, 2019. Contract liabilities, which are current and noncurrent, are included in "Deferred revenues" and "Other liabilities" in the consolidated balance sheets, respectively, as of December 31, 2019 and 2018.

The Company’s most significant remaining performance obligations relate to providing customers with the right to use and update the online content over the remaining contract term. Revenues expected to be recognized in the future related to performance obligations, included within our deferred revenue and other liabilities, that are unsatisfied were $443.2 million and $385.1 million as of December 31, 2019 and 2018, respectively. Our disclosure of the timing for satisfying the performance obligation is based on the requirements of contracts with customers. However, from time to time, these contracts may be subject to modifications, impacting the timing of satisfying the performance obligations. These performance obligations, which are expected to be satisfied within one year, comprised approximately 99% of the balance as of December 31, 2019 and 2018.

The Company recognizes an asset for incremental costs of obtaining a contract with a customer if it expects the benefits of those costs to be longer than one year. As of December 31, 2019 and 2018, the Company had deferred commissions of $63.7 million and $49.5 million, respectively, which have been included in "Prepaid expenses" and "Other assets" in the accompanying consolidated balance sheets.

Fair Value Measurements

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 consolidated balance sheets. Such assets and liabilities include amounts for both financial and non-financial instruments. To increase consistency and comparability of assets and liabilities recorded at fair value, 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 is internally-developed, and considers risk premiums that a market participant would require.

The fair value of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, and short-term debt approximate their carrying amounts because of the short-term nature of these instruments. The investments in registered investment companies, which are Level 1 assets measured at fair value on a recurring basis using quoted prices in active markets multiplied by the number of shares owned, were $3.6 million and $3.3 million as of December 31, 2019 and 2018, respectively. The investments in registered investment companies have been included in "Other current assets" in the consolidated balance sheets as of December 31, 2019 and 2018.

The Company elected not to carry its long-term debt at fair value. The carrying value of the long-term debt represents the amortized cost, inclusive of unamortized premium, and net of 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 December 31, 2019 and 2018 respectively:



	Fair Value Hierarchy	2019				2018
	Fair Value Hierarchy	Carrying Value		Estimated Fair Value		Carrying Value		Estimated Fair Value
Financial instrument not carried at fair value:
Long-term debt excluding finance lease liabilities and syndicated revolving credit facility debt issuance costs	Level 2	$	2,650.4	$	2,902.2	$	2,033.9	$	2,347.4

As of December 31, 2019 and 2018, the Company had securities of $14.0 million and $11.5 million, which were accounted for as cost-based investments under ASC 323-10-25, The Equity Method of Accounting for Investments in Common Stock ("ASC 323-10-25"). The Company does not have the ability to exercise significant influence over the investees’ operating and financial policies. As of December 31, 2019 and 2018, the Company also had an investment in a limited partnership of $13.1 million and $5.9 million, respectively, accounted for in accordance with ASC 323-10-25 as an equity method investment. These investments were included in "Other assets" in the accompanying consolidated balance sheet.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Leases [Abstract]

Leases

Leases:

In February 2016, the FASB established ASC 842, which focused on increasing transparency and comparability related to leases among organizations by requiring the recognition of ROU assets and lease liabilities on the balance sheet. The core principle of ASC 842 is that a lessee should recognize the assets and liabilities that arise from leases. This concept requires a lessee to recognize on the balance sheet a ROU asset representing the lessee’s right to use the underlying asset over the duration of the lease term and a liability to make lease payments. Most prominent among the changes in the standard is the recognition of ROU assets and lease liabilities by lessees for those leases classified as operating leases. Under the standard, disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The Company is also required to recognize and measure leases existing at, or entered into after the adoption date using a modified retrospective approach, with certain practical expedients available.

The Company adopted ASC 842 on January 1, 2019 using the modified retrospective approach and elected the transition relief package of practical expedients by applying previous accounting conclusions under ASC 840 to all leases that existed prior to the transition date. As a result, the Company did not reassess 1) whether existing or expired contracts contain leases, 2) lease classification for any existing or expired leases, and 3) whether lease origination costs qualified as initial direct costs. The Company did not elect the practical expedient to use hindsight in determining a lease term and impairment of the ROU assets at the adoption date. The Company did not separate lease components from non-lease components for leased corporate offices and data centers. The election applies to all operating leases where fixed rent payments incorporate common area maintenance. For leases where the election does not apply, the common area maintenance is billed by the landlord separately. Additionally, the Company did not capitalize any short-term leases, generally defined as a lease term of less than one year, in accordance with ASC 842.

The following table presents the cumulative effect of the changes made to the accompanying consolidated balance sheets as of January 1, 2019 as a result of the adoption of ASC 842:

Leases

Leases:

In February 2016, the FASB established ASC 842, which focused on increasing transparency and comparability related to leases among organizations by requiring the recognition of ROU assets and lease liabilities on the balance sheet. The core principle of ASC 842 is that a lessee should recognize the assets and liabilities that arise from leases. This concept requires a lessee to recognize on the balance sheet a ROU asset representing the lessee’s right to use the underlying asset over the duration of the lease term and a liability to make lease payments. Most prominent among the changes in the standard is the recognition of ROU assets and lease liabilities by lessees for those leases classified as operating leases. Under the standard, disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The Company is also required to recognize and measure leases existing at, or entered into after the adoption date using a modified retrospective approach, with certain practical expedients available.

The Company adopted ASC 842 on January 1, 2019 using the modified retrospective approach and elected the transition relief package of practical expedients by applying previous accounting conclusions under ASC 840 to all leases that existed prior to the transition date. As a result, the Company did not reassess 1) whether existing or expired contracts contain leases, 2) lease classification for any existing or expired leases, and 3) whether lease origination costs qualified as initial direct costs. The Company did not elect the practical expedient to use hindsight in determining a lease term and impairment of the ROU assets at the adoption date. The Company did not separate lease components from non-lease components for leased corporate offices and data centers. The election applies to all operating leases where fixed rent payments incorporate common area maintenance. For leases where the election does not apply, the common area maintenance is billed by the landlord separately. Additionally, the Company did not capitalize any short-term leases, generally defined as a lease term of less than one year, in accordance with ASC 842.

Acquisition Escrows and Related Liabilities

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 dates, as well as a portion of the contingent payments. During the years ended December 31, 2019 and 2018, the Company released $25.2 million and $23.8 million of indemnity escrows related to various acquisitions. During the year ended December 31, 2017, the Company released $3.8 million of indemnity escrows, of which $3.2 million related to a 2015 acquisition of The PCI Group. At December 31, 2019 and 2018, the current portion of the escrows amounted to $0.5 million and $31.2 million, and the noncurrent portion of the escrows amounted to $10.5 million and $8.7 million, respectively. The current and noncurrent portions of the escrows have been included in “Other current assets” and "Other noncurrent assets" in the accompanying consolidated balance sheets, respectively.

The acquisitions of Validus, PowerAdvocate, Rebmark, Healix and ENI include acquisition related contingencies, for which the sellers of these acquisitions could receive additional payments by achieving the specific predetermined revenue, EBITDA, and EBITDA margin earn-out targets for exceptional performance. The Company believes that the liabilities recorded as of December 31, 2019 reflect the best estimate of acquisition contingent payments. The associated current acquisition-related liabilities were $111.2 million and $12.6 million as of December 31, 2019 and December 31, 2018, respectively. The associated noncurrent acquisition-related liabilities were $0.2 million and $28.3 million as of December 31, 2019 and December 31, 2018, respectively.

The reconciliation between the Company’s effective tax rate and the statutory tax rate is as follows for the years ended December 31:



	2019		2018		2017
Federal statutory rate	21.0	%	21.0	%	35.0	%
State and local taxes, net of federal tax benefit	2.8	%	2.8	%	2.6	%
Foreign tax differentials	(0.8	)%	(0.8	)%	(1.8	)%

Other	0.1	%	—	%	(0.7	)%
Effective tax rate	20.9	%	16.8	%	19.7	%

The increase in the effective tax rate in 2019 compared to 2018 was primarily due to the impact of lower tax benefits from equity compensation in the current period versus the prior period as well as nondeductible earn-out expenses in the current period.

The tax effects of significant items comprising the Company’s deferred tax assets as of December 31 are as follows:



	2019			2018
Deferred tax assets:
Employee wages, pension, and other benefits	$	13.0		$	20.9

Deferred tax liabilities		(431.5	)		(395.8	)
Deferred tax liabilities, net	$	(346.2	)	$	(339.5	)

The net deferred tax liabilities of $346.2 million consist primarily of timing differences involving depreciation and amortization.

The ultimate realization of the deferred tax assets depends on the Company’s ability to generate sufficient taxable income in the future. The Company has provided a valuation allowance against the deferred tax assets associated with the interest expense deduction limitation in the U.K. The Company has also provided for a valuation allowance against the deferred tax assets associated with the net operating losses of certain subsidiaries. The Company’s net operating loss carryforwards expire as follows:



Years Ending	Amount
2020 - 2027	$	24.9
2028 - 2032		14.6
2033 - 2039		189.6
Total	$	229.1

A valuation allowance has been established based on the Company’s evaluation of the likelihood of utilizing these benefits before they expire. The Company has determined that the generation of future taxable income from certain subsidiaries to fully realize the deferred tax assets is uncertain. Other than these items, the Company has determined, based on the Company’s historical operating performance, that taxable income of the Company will more likely than not be sufficient to fully realize the deferred tax assets.

As of December 31, 2019, the Company has not made a provision for U.S. or additional foreign withholdings taxes for any additional outside basis difference inherent in its foreign subsidiaries, as these amounts continue to be indefinitely reinvested in foreign operations. Determining the amount of unrecognized deferred tax liability related to any additional outside basis difference in these entities is not practicable. The Company does not rely on these unremitted earnings as a source of funds for its domestic business as it expects to have sufficient cash flow in the U.S. to fund its U.S. operational and strategic needs.

The Company follows ASC No. 740-10 which prescribes a comprehensive model for the financial statement recognition, measurement, presentation, and disclosure of uncertain tax positions taken or expected to be taken in income tax returns. For each tax position, the Company must determine whether it is more likely than not that the position will be sustained upon examination based on the technical merits of the position, including resolution of any related appeals or litigation. A tax position that meets the more likely than not recognition threshold is then measured to determine the amount of benefit to

recognize within the financial statements. No benefits may be recognized for tax positions that do not meet the more likely than not threshold. A reconciliation of the beginning and ending amount of unrecognized tax benefit is as follows:



	2019			2018			2017
Unrecognized tax benefit as of January 1	$	17.4		$	16.3		$	16.8
Gross increase in tax positions in prior period		0.6			2.0			1.7
Gross decrease in tax positions in prior period		(3.3	)		(0.1	)		(1.2	)
Settlements		(2.4	)		(0.3	)		—
Lapse of statute of limitations		(0.8	)		(0.5	)		(1.0	)
Unrecognized tax benefit as of December 31	$	11.5		$	17.4		$	16.3

Of the total unrecognized tax benefits as of December 31, 2019, 2018, and 2017, $8.6 million, $14.4 million, and $13.2 million, respectively, represent the amounts that, if recognized, would have a favorable effect on the Company’s effective tax rate in any future periods.

The total gross amount of accrued interest and penalties for the years ended December 31, 2019, 2018, and 2017 was $4.6 million, $5.7 million, and $4.5 million, respectively. The Company’s practice is to recognize interest and penalties associated with income taxes as a component of “Provision for income taxes” in the accompanying consolidated statements of operations.

The Company does not expect a significant increase in unrecognized benefits related to federal, state, or foreign tax exposures within the coming year. In addition, the Company believes that it is reasonably possible that approximately $1.1 million of its currently remaining unrecognized tax positions, each of which is individually insignificant, may be recognized by the end of 2020 as a result of a combination of audit settlements and lapses of statute of limitations, net of additional uncertain tax positions.

The Company is subject to tax in the U.S., various state, and foreign jurisdictions. The Company joined by its domestic subsidiaries, files a consolidated income tax return for Federal income tax purposes. With a few exceptions, none of which are material to the Company’s consolidated financial statements as of December 31, 2019, the Company is no longer subject to U.S. federal, state and local, or non-US income tax examinations by tax authorities for tax years before 2015. In New Jersey, the Company is being audited for the years ended December 31, 2013 through 2018 with a statute extension until October 31, 2020. In Massachusetts, the Company is being audited for the years ended December 31, 2014 through 2015 with a statute extension until June 30, 2020. The Company is also under audit in New York for the years ended December 31, 2015 through 2017 with a statute extension until October 2, 2020. The Company does not expect that the results of these examinations will have a material effect on its financial position, results of operations, or cash flow.

⁽¹⁾Refer to Note 8. Leases

⁽²⁾ The Company offered an additional issuance of these notes on September 6, 2019.

Accrued interest associated with the Company’s outstanding debt obligations was $19.0 million and $17.2 million as of December 31, 2019 and 2018, respectively, and included in “Accounts payable and accrued liabilities” within the accompanying consolidated balance sheets. Interest expense associated with the Company’s finance lease and outstanding debt obligations, including amortization of debt issuance costs and original discounts, was $125.7 million, $128.2 million and $119.4 million for the years ended December 31, 2019, 2018 and 2017, respectively.

Senior Notes

On January 15, 2019, the Company utilized borrowings from its the Credit Facility and cash from operations to repay the 4.875% senior notes in full in an amount of $250.0 million.

On March 6, 2019, the Company completed an issuance of $400.0 million aggregate principal amount of 4.125% senior notes due 2029 (the "2029 notes"), which were issued at a discount of $2.1 million and the Company incurred debt issuance costs of $3.7 million. On September 6, 2019, the Company completed an additional issuance of $200.0 million aggregate principal amount of the 2029 notes that were issued at a premium of $21.8 million and the Company incurred debt issuance costs of $1.9 million. The 2029 notes mature on March 15, 2029 and accrue interest at a fixed rate of 4.125% per annum. Interest is payable semiannually on the 2029 notes on March 15th and September 15th of each year, beginning on March 15, 2020. The original issue discount, original issue premium and debt issuance costs were recorded in "Long-term debt" in the accompanying consolidated balance sheets and these costs will be amortized to "Interest expense" in the accompanying consolidated statements of operations over the life of the 2029 notes. The net proceeds from the issuance of the 2029 notes were utilized to support the acquisition of Genscape (See Note 10. Acquisitions), partially repay the Credit Facility and for general corporate purposes. The indenture governing the 2029 notes restricts the Company's ability to, among other things, create certain liens, enter into sale/leaseback transactions and consolidate with, sell, lease, convey or otherwise transfer all or substantially all of the Company's assets, or merge with or into, any other person or entity. As of December 31, 2019 and

December 31, 2018, the Company had senior notes with an aggregate principal amount of $2,650.0 million and $2,300.0 million outstanding, respectively, and was in compliance with their financial and other debt covenants.

Syndicated Revolving Credit Facility

On August 15, 2019, the Company entered into the Fourth Amendment (the "Amendment") to the Credit Facility with Bank of America N.A., HSBC Bank USA, N.A., JP Morgan Chase Bank, N.A., Wells Fargo Bank, National Association, Citibank, N.A., Credit Suisse AG, Cayman Islands Branch, Morgan Stanley Bank, N.A., TD Bank, N.A., and the Northern Trust Company, which reduced the borrowing capacity from $1,500.0 million to $1,000.0 million, extended the maturity date to August 15, 2024, and amended the pricing grid. The Amendment is considered as a modification of existing debt under U.S. GAAP. Interest on borrowings under the Amendment is payable at an interest rate of LIBOR plus 1.0% to 1.625%, depending upon the public debt rating. A commitment fee on any unused balance is payable periodically and may range from 8.0 to 20.0 basis points based upon the public debt rating. The Amendment also contains certain financial and other covenants that, among other things, impose certain restrictions on indebtedness, liens, investments, and capital expenditures. These covenants place restrictions on mergers, asset sales, sale/leaseback transactions, and certain transactions with affiliates. The financial covenants require that, at the end of any fiscal quarter, the Company has a consolidated funded debt leverage ratio of less than 3.5 to 1.0. At the election of the Company, the maximum consolidated funded debt leverage ratio could be permitted to increase one time each to 4.0 to 1.0 and 4.25 to 1.0. The Credit Facility may be used for general corporate purposes, including working capital needs and capital expenditures, acquisitions, dividends and the share repurchase program (the "Repurchase Program"). As of December 31, 2019, the Company was in compliance with all financial and other debt covenants under the Credit Facility. As of December 31, 2019 and 2018, the available capacity under the Credit Facility was $500.2 million and $1,078.9 million, net of the letters of credit of $4.8 million and $6.1 million, respectively. In connection with the Amendment, the Company incurred additional debt issuance costs of $0.7 million, which will be amortized to "Interest expense" within the accompanying consolidated statements of operations over the remaining life of the Credit Facility. In addition, due to the reduction in the available capacity as part of the Amendment, previously capitalized debt issuance costs of $0.8 million were written off and recorded to "Interest expense" in the consolidated statements of operations for the year ended December 31, 2019. Subsequent to December 31, 2019, the Company had borrowings of $40.0 million and repayments of $130.0 million under the Credit Facility.

Equity [Abstract]

Stockholders' Equity

Stockholders’ Equity:

The Company has 2,000,000,000 shares of authorized common stock as of December 31, 2019 and 2018. The common shares have rights to any dividend declared by the board of directors, subject to any preferential or other rights of any outstanding preferred stock, and voting rights to elect all eleven members of the board of directors.

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 December 31, 2019.

At December 31, 2019, 2018 and 2017, the adjusted closing price of Verisk common stock was $149.34, $108.28, and $95.33 per share, respectively.

On February 13, 2019, April 29, 2019, July 24, 2019, and October 23, 2019, the Company’s Board approved a cash dividend of $0.25 per share of common stock issued and outstanding to the holders of record as of March 15, 2019, June 14,

2019, September 13, 2019, and December 13, 2019 respectively. The cash dividend of $40.9 million, $41.0 million, and $40.8 million, and $40.8 million was paid on March 29, 2019, June 28, 2019, September 30, 2019, and December 31, 2019 and recorded as a reduction to retained earnings, respectively.

Share Repurchase Program

Since May 2010, the Company has authorized repurchases of up to $3,800.0 million of its common stock through its Repurchase Program, inclusive of the $500.0 million authorization approved by the board on February 12, 2020. Since the introduction of share repurchase as a feature of the Company's capital management strategies in 2010, the Company has repurchased shares with an aggregate value of $3,172.4 million. As of December 31, 2019, the Company had $127.6 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 Verisk 2013 Equity Incentive Plan (the "2013 Incentive Plan"), the Verisk 2009 Equity Incentive Plan (the “2009 Incentive Plan”), the Company's sharesave plan (“UK Sharesave Plan”), and the employee stock purchase plan ("ESPP") 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.

In December 2018, March 2019, June 2019, and September 2019 the Company entered into Accelerated Share Repurchase ("ASR") agreements to repurchase shares of its common stock for an aggregate purchase price of $75.0 million, $50.0 million, $75.0 million, and $50.0 million, respectively, with Morgan Stanley & Co. LLC and HSBC Bank USA, N.A. The ASR agreements are each accounted for as a treasury stock transaction and a forward stock purchase agreement indexed to the Company's common stock. The forward stock purchase agreements are each classified as an equity instrument under ASC 815-40, Contracts in Entity's Own Equity ("ASC 815-40") and were deemed to have a fair value of zero at the respective effective date. Upon payments of the aggregate purchase price on January 2, 2019, April 1, 2019, July 1, 2019, and October 1, 2019, the Company received an aggregate delivery of 550,257, 300,752, 409,668, and 252,940 shares of its common stock at a price of $109.04, $133.00, $146.46, and $158.14 respectively. Upon the final settlement of the ASR agreements in March 2019, June 2019, September 2019, and November 2019, the Company received additional shares of 86,333, 60,721, 81,048, and 81,862 respectively, as determined by the volume weighted average share price of Verisk's common stock during the term of the ASR agreements. The aggregate purchase price was recorded as a reduction to stockholders' equity in the Company's consolidated statements of changes in stockholders' equity for the year ended December 31, 2019. These repurchases of 1,823,581 shares for the year ended December 31, 2019 resulted in a reduction of outstanding shares used to calculate the weighted average common shares outstanding for basic and diluted earnings per share ("EPS").

During the years ended December 31, 2019 and 2018, the Company repurchased 2,178,151 and 3,882,467 shares of common stock as part of the Repurchase Program, inclusive of the ASRs, at a weighted average price of $137.73 and $112.97 per share, respectively. The Company utilized cash from operations and borrowings from its Credit Facility to fund these repurchases.

Treasury Stock

As of December 31, 2019, the Company’s treasury stock consisted of 380,841,474 shares of common stock. During the years ended December 31, 2019, 2018 and 2017, the Company transferred 1,369,305, 2,973,947 and 1,319,518 shares of common stock, under the 2013 Incentive Plan, and 2009 Incentive Plan, from the treasury shares at a weighted average price of $9.72, $8.71 and $8.13 per share, respectively.

Share-based Payment Arrangement [Abstract]

Compensation Plans

Compensation Plans:

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) (the “Code”), and to provide employee equity participation in the Company through the employee stock ownership plan (“ESOP”) accounts.

Under the KSOP, eligible employees may make pre-tax and after-tax cash contributions as a percentage of their compensation, subject to certain limitations under the applicable provisions of the Code. The maximum pre-tax contribution that can be made to the 401(k) account as determined under the provisions of Code Section 401(g) is $19.0 thousand for 2019, $18.5 thousand for 2018 and $18.0 thousand for 2017. Certain eligible participants (age 50 and older) may contribute an additional $6.0 thousand on a pre-tax basis for 2019, 2018 and 2017. After-tax contributions are limited to 10.0% of a participant’s compensation. The matching contributions prior to April 1, 2018 were primarily equal to 75.0% of the first 6.0% of the participant’s contribution. Effective April 1, 2018, the Company amended the KSOP to increase the matching contributions to 87.5% of the first 6.0% of the participant’s contribution. Effective January 1, 2019, the Company increased the matching contributions to 100.0% of the first 6.0% of the participant’s contribution. The 401(k) matching contributions under

the KSOP for the years ended December 31, 2019, 2018 and 2017, were $31.0 million, $22.0 million, $15.6 million, respectively; which, at the option of the Company, were funded in cash or in common stock issued from treasury shares.

In 2005, the Company established the ISO Profit Sharing Plan (the “Profit Sharing Plan”), a defined contribution plan, to replace the qualified pension plan for all eligible employees hired on or after March 1, 2005. The Profit Sharing Plan is a component of the KSOP. Eligible employees participated in the Profit Sharing Plan if they completed 1,000 hours of service each plan year and were employed on December 31 of that year. The Company can make a discretionary contribution to the Profit Sharing Plan based on the annual performance of the Company. Participants vest once they have completed four years and 1,000 hours of service. For the years ended December 31, 2019, 2018 and 2017, there were no profit sharing contributions.

Equity Compensation Plans

All of the Company’s outstanding stock options, restricted stock and PSUs are covered under the 2013 Incentive Plan or 2009 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. The number of shares of common stock available for issuance under the 2013 Incentive Plan is 15,700,000 and such amount shall be reduced on a 1-for-1 basis for every share issued that is subject to an option or stock appreciation right and on a 2.5-for-1 basis for every share issued that is subject to an award other than an option or stock appreciation right. Shares that were subject to an award under the 2013 Incentive Plan that become forfeited, expired or otherwise terminated shall again be available for issuance under the 2013 Incentive Plan on a 1-for-1 basis if the shares were subject to options or stock appreciation rights, and on an 2.5-for-1 basis if the shares were subject to awards other than options or stock appreciation rights. The Company has granted equity awards to key employees and directors. The ultimate realization of the PSUs may range from 0% to 200% of the recipient’s target levels established on the grant date. As of December 31, 2019, there were 4,391,470 shares of common stock reserved and available for future issuance.

A summary of the status of the stock options, restricted stock and PSUs awarded under the 2013 Incentive Plan as of December 31, 2019, 2018 and 2017 and changes during the years is presented below.

Intrinsic value for stock options is calculated based on the exercise price of the underlying awards and the quoted price of Verisk’s common stock as of the reporting date. Excess tax benefits of $23.2 million, $48.9 million and $19.0 million from exercised stock options were recorded as income tax benefit in the accompanying consolidated statements of operations for the years ended December 31, 2019, 2018 and 2017, respectively. Stock based compensation expense for the years ended December 31, 2019, 2018 and 2017 was $42.7 million, $38.5 million and $31.8 million, respectively. Cash received from stock option exercises for the years ended December 31, 2019, 2018 and 2017 was $52.4 million, $87.3 million and $35.0 million, respectively. As of December 31, 2019, the weighted average remaining contractual terms were 5.76 years and 4.57 years for outstanding and exercisable stock options, respectively. As of December 31, 2018, the weighted average remaining contractual terms were 5.87 years and 4.55 years for outstanding and exercisable stock options, respectively.

For the year ended December 31, 2019 and 2018, certain employees had restricted stock vesting and covered the aggregate statutory minimum tax withholding of $5.5 million and $3.7 million through a net settlement of 40,578 shares and 35,637 shares, respectively.

As of December 31, 2019, there was $92.0 million of total unrecognized compensation cost, exclusive of the impact of vesting upon retirement eligibility, related to nonvested share-based compensation arrangements granted under the 2013 Incentive Plan. That cost is expected to be recognized over a weighted-average period of 2.51 years. The total grant date fair value of options vested during the years ended December 31, 2019, 2018, and 2017 was $17.4 million, $16.8 million and $16.6 million, respectively. The total grant date fair value of restricted stock vested during the years ended December 31, 2019, 2018 and 2017 was $20.2 million, $18.6 million and $17.6 million, respectively. The total grant date fair value of PSUs vested during the years ended December 31, 2019 and 2018 was $4.2 million and $1.5 million, respectively.

The Company’s UK Sharesave Plan offers qualifying employees in the United Kingdom the opportunity to own shares of the Company’s common stock. Employees who elect to participate are granted stock options, of which the exercise price is equal to the adjusted closing price of the Company’s common stock on the grant date discounted by 5%, and enter into a savings contract, the proceeds of which are then used to exercise the options upon the three-year maturity of the savings contract. During the years ended December 31, 2019 and 2018, the Company granted 18,713 and 19,247 stock options under the UK Sharesave Plan at a discounted exercise price of $136.35 and $101.27, respectively. As of December 31, 2019, there were 462,040 shares of common stock reserved and available for future issuance under the UK Sharesave Plan.

The Company also offers eligible employees the opportunity to participate in an ESPP. Under the ESPP, participating employees may authorize payroll deductions of up to 20.0% of their regular base salary and up to 50.0% of their short-term incentive compensation, both of which in total may not exceed $25.0 thousand in any calendar year, to purchase shares of the Company’s common stock at a 5.0% discount of its fair market value at the time of purchase. In accordance with ASC 718, the ESPP is noncompensatory as the purchase discount is 5.0% or less from the fair market value, substantially all employees that meet limited employment qualifications may participate, and it incorporates no option features. During the years ended December 31, 2019, 2018 and 2017, the Company issued 30,705, 30,550 and 29,605 shares of common stock at a weighted

average discounted price of $141.17, $104.71 and $81.38, respectively. As of December 31, 2019, there were 1,292,768 shares of common stock reserved and available for future issuance under the ESPP.

Retirement Benefits [Abstract]

Pension and Postretirement Benefits

Pension and Postretirement Benefits:

The Company has 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. Prior to the freeze, the Company applied a cash balance formula to determine future benefits. Under the cash balance formula, each participant has an account, which was credited annually based on salary rates determined by years of service, as well as the interest earned on the previous year-end cash balance. The Company also has a non-qualified frozen supplemental cash balance plan (“SERP”) for certain employees. The SERP is funded from the general assets of the Company.

The Pension Plan’s funding policy is to contribute annually at an amount between the minimum funding requirements set forth in the Employee Retirement Income Security Act of 1974 and the maximum amount that can be deducted for federal income tax purposes. The minimum contribution requirement was and is expected to be $0 in 2019 and 2020, respectively. The Company contributed $0.7 million and $1.0 million to the SERP in 2019 and 2018, respectively, and expects to contribute $0.9 million in 2020.

The Company also provides certain healthcare and life insurance benefits for both 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 Company does not expect to contribute to the Postretirement Plan in 2020.

The following table sets forth the changes in the benefit obligations and the plan assets, the (funded) unfunded status of the Pension Plan, SERP and Postretirement Plan, and the amounts recognized in the Company’s consolidated balance sheets at December 31:

Expected return on plan assets	7.00	%	7.00	%	7.25	%	2.00	%	2.00	%	3.00	%

The following table presents the estimated future benefit payments for the respective plans. The future benefit payments for the Postretirement Plan are net of the federal Medicare subsidy.



	Pension Plan and SERP		Postretirement Plan
	Gross Benefit Amount		Gross Benefit Amount		Medicare Subsidy Payments			Net Benefit Amount
2020	$	30.8	$	1.4	$	(0.2	)	$	1.2
2021	$	30.4	$	1.2	$	(0.2	)	$	1.0
2022	$	29.9	$	1.1	$	(0.2	)	$	0.9
2023	$	29.9	$	1.0	$	(0.1	)	$	0.9
2024	$	29.6	$	0.8	$	—		$	0.8
2025-2029	$	138.8	$	2.8	$	(0.1	)	$	2.7

The healthcare cost trend rate for 2020 was 8.25% gradually decreasing to 4.50% in 2035. Assumed healthcare cost trend rates have a significant effect on the amounts reported for the healthcare plan. However, a 1.00% change in assumed healthcare cost trend rates would have an immaterial effect to our postretirement benefit obligation.

The subsidy benefit from the Medicare Prescription Drug, Improvement and Modernization Act of 2003 reduced the Company’s accumulated postretirement benefit assets by approximately $0.8 million and $0.9 million as of December 31, 2019 and 2018, respectively. The subsidy cost increased the net periodic benefit cost by approximately $48.5 thousand and $51.0 thousand in fiscal 2019 and 2018, respectively, and reduced the net periodic benefit cost by approximately $2.0 thousand in fiscal 2017.

The expected return on the Pension Plan assets as of December 31, 2019 and 2018 was 6.75% and 7.00%, respectively, which was determined by taking into consideration the Company’s analysis of its actual historical investment returns to a broader long-term forecast after adjusting for the target investment allocation and reflecting the current economic environment. The Company’s investment guidelines targeted investment allocation of 60% equity securities and 40% debt securities as of December 31, 2019 and 2018. The Pension Plan assets consist primarily of investments in various fixed income and equity funds. Investment guidelines are established with each investment manager. These guidelines provide the parameters within which the investment managers agree to operate, including criteria that determine eligible and ineligible securities, diversification requirements and credit quality standards, where applicable. Investment managers are prohibited from entering into any speculative hedging transactions. The investment objective is to achieve a maximum total return with strong emphasis on preservation of capital in real terms. As of December 31, 2019 and 2018, the domestic equity portion of the total portfolio ranged between 40% and 60%. The international equity portion of the total portfolio ranged between 10% and 20%. The fixed income portion of the total portfolio ranged between 20% and 40%.

The asset allocation at December 31, 2019 and 2018, and target allocation by asset category are as follows:



Asset Category	Target Allocation		Percentage of Plan Assets
Asset Category	Target Allocation		2019		2018
Equity securities	60.0	%	53.7	%	49.2	%
Debt securities	40.0	%	37.9	%	41.9	%
Other	—	%	8.4	%	8.9	%
Total	100.0	%	100.0	%	100.0	%

The Company has used the target investment allocation to derive the expected return as the Company believes this allocation will be retained on an ongoing basis that will be commensurate with the projected cash flows of the plan. The expected return for each investment category within the target investment allocation is developed using average historical rates of return for each targeted investment category, considering the projected cash flow of the Pension Plan. The difference between this expected return and the actual return on plan assets is generally deferred and recognized over subsequent periods through future net periodic benefit costs. The Company believes that the use of the average historical rates of returns is consistent with the timing and amounts of expected contributions to the plans and benefit payments to plan participants. These considerations provide the basis for reasonable assumptions with respect to the expected long-term rate of return on plan assets.

The Company also maintains a voluntary employees beneficiary association plan (the “VEBA Plan”) under Section 501(c)(9) of the Internal Revenue Code to fund the Postretirement Plan. The asset allocation for the VEBA Plan at December 31, 2019 and 2018 was 100% in debt securities.

There were no transfers among Levels 1, 2 or 3 for the years ended December 31, 2019 and 2018. Refer to Note 7. Fair Value Measurements for further discussion with respect to fair value hierarchy. The following table summarizes the fair value measurements by level of the Pension Plan and Postretirement Plan assets:

Segment Reporting [Abstract]

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 reportable 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 CEO is identified as the CODM as defined by ASC 280-10.

The Company previously reported results based on its two operating segments, Decision Analytics and Risk Assessment. During the first quarter of 2018, the CODM changed how he makes operating decisions, assesses the performance of the business, and allocates resources in a manner that caused its operating segments to change. Consequently, effective as of the first quarter of 2018, the operating segments of the Company are based on three vertical markets it serves: Insurance, Energy and Specialized Markets, and Financial Services. These three operating segments are also the Company's reportable segments, which have been recast to reflect the new segments for the year ended December 31, 2017.

Each of the Company's reportable segments, Insurance, Energy and Specialized Markets, and Financial Services has a portion of its revenue from more than one of the three revenue types described within the revenue recognition policy within Note 2. Basis of Presentation and Summary of Significant Accounting Policies. Below is the overview of the solutions offered within each reportable segment.

Insurance: 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, which are accessed via a hosted platform. The Company also develops solutions that its customers use to analyze key processes in managing risk. 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, ranging from hurricanes to earthquakes. The Company develops catastrophe and extreme event models and offers solutions covering natural and man-made risks, including acts of terrorism. The Company further develops solutions that allow customers to quantify costs after loss events occur. The Company's multitier, multispectral terrestrial imagery and data acquisition, processing, analytics, and distribution system using the remote sensing and machine learning technologies help gather, store, process, and deliver geographic and spatially referenced information that supports uses in many markets. Additionally, the Company offers fraud-detection solutions including review of data on claim histories, analysis of claims to find emerging patterns of fraud, and identification of suspicious claims in the insurance sector. The Company’s underwriting & rating, insurance anti-fraud claims, catastrophe modeling, and loss quantification are included in this segment.

Energy and Specialized Markets: The Company is a leading provider of data analytics via hosted platform for the global energy, chemicals, and metals and mining industries. Its research and consulting solutions focus on exploration strategies and screening, asset development and acquisition, commodity markets, and corporate analysis in the areas of business environment, business improvement, business strategies, commercial advisory, and transaction support. The Company gathers and manages proprietary information, insight, and analysis on oil and gas fields, mines, refineries and other assets across the interconnected global energy sectors to advise customers in making asset investment and portfolio allocation decisions. The Company also helps businesses and governments better anticipate and manage climate and weather-related risks. The Company's analytical tools measure and observe environmental properties and translate those

measurements into actionable information based on customer needs. In addition, the Company provides market and cost intelligence to energy companies to optimize financial results. The Company further offers a suite of data and information services that enable improved compliance with global Environmental Health and Safety requirements related to the safe manufacturing, distribution, transportation, usage, and disposal of chemicals and products. The Company’s energy business, environmental health and safety services and, weather risk solutions are included in this segment.

Financial Services: The Company maintains a bank account consortia to provide competitive benchmarking, decisioning algorithms, business intelligence, and customized analytic services that help financial institutions, payment networks and processors, alternative lenders, regulators and merchants make better strategy, marketing, and risk decisions. Customers apply the Company's solutions in the areas of tailored data management and media effectiveness that include business intelligence platforms, profile views, mobile data solutions, enterprise database services, and fraud risk scoring algorithms for marketing, fraud, and risk mitigation. In addition, the Company's bankruptcy management solutions assist creditors, debt servicing businesses and credit services to enhance regulatory compliance by eliminating stay violation and portfolio valuation risk.

The three 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. See Note 6. Revenues for information on disaggregated revenues by type of service and by country.

The following table provides the Company’s revenue and EBITDA by reportable segment for the years ended December 31, as well as a reconciliation of EBITDA to income before income taxes for all periods presented in the accompanying consolidated statements of operations:

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. In the case of the 360Value Litigation, this is primarily because the matter is generally in early stages and discovery has not yet commenced. 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. 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 alleged that the Company’s Roof InSight (now known as Geomni Roof), Property InSight product (now known as Geomni Property) and Aerial Sketch product in combination with the Company's Xactimate product infringe seven patents owned by Eagle View and Pictometry namely, Patent Nos. 8,078,436 (the "436 patent"), 8,170,840 (the "840 patent"), 8,209,152 (the "152 patent"), 8,542,880 (the "880 patent"), 8,818,770 (the "770 patent"), 8,823,732 (the "732 patent"), and 8,825,454 (the "454 patent"). On November 30, 2015, plaintiffs filed a First Amended Complaint adding Patent Nos. 9,129,376 (the "376 patent") and 9,135,737 (the "737 patent") to the lawsuit. The First Amended Complaint sought an entry of judgment by the Court that defendants have and continue to directly infringe and/or indirectly infringe, including by way of inducement the Patents-in-Suit, permanent injunctive relief, damages, costs and attorney’s fees. On May 19, 2017, the District Court entered a Joint Stipulated Order of Partial Dismissal with Prejudice dismissing all claims or assertions pertaining to the 880 and 732 patents, and certain asserted claims of the 436, 840, 152, 770, 454, 376 and 737 patents (collectively the “Patents in Suit”). Eagle View further reduced the number of asserted claims pertaining to the Patents in Suit to 18 asserted claims. Thereafter, Eagle View dropped the 152 patent and further reduced the number of asserted claims from the six remaining Patents in Suit to 11 asserted claims. Fact discovery and expert discovery closed in 2018 and the Company's summary judgment motions were fully submitted on October 26, 2018. On December 6, 2018, the Court denied Eagle View’s motion for summary judgment that a key prior art reference be excluded. On December 20, 2018, the Court denied the Company’s motion for summary judgment of equitable estoppel. On January 29, 2019, the Court denied the Company’s motion for summary judgment of unpatentability pursuant to Section 101 of the Patent Act. Thereafter, Eagle View dropped the 737 patent and further reduced the number of asserted claims from the five remaining Patents in Suit to 6 asserted claims. On September 25, 2019, following a trial, the jury determined that the Company had willfully infringed the 6 asserted claims, and assessed damages in the amount of $125.0 million, for which the Company has recorded a reserve. The impact associated with the reserve was included in the "Selling, general and administrative" in the accompanying consolidated statements of operations for the year ended December 31, 2019. After trial, Eagle View moved for a temporary restraining order (“TRO”) and a permanent injunction preventing the Company’s sales of the Geomni Roof, Geomni Property and Aerial Sketch products in combination with Xactimate. The Court granted the motion for a TRO on September 26, 2019 and on October 18, 2019, issued an Order permanently enjoining the Company's sales of the Geomni Roof, Geomni Property and Aerial Sketch products in combination with Xactimate. The Company plans to appeal these results. Eagle View has petitioned the Court to award up to treble damages, together with fees and expenses. The parties’ post- trial motions were fully submitted on December 10, 2019 and the parties are awaiting a decision on these motions. The Company has established a $125.0 million reserve in connection with this litigation, however, at this time it is not reasonably possible to determine the ultimate resolution of this matter. 360Value Litigation On December 10, 2018, the Company was served with a First Amended Complaint filed in the United States District Court for the Northern District of California titled Sheahan, et al. v. State Farm General Insurance Co., Inc., et al. The action is brought by California homeowners, on their own behalf and on behalf of an unspecified putative class of State Farm policyholders whose homes were damaged or lost during the Northern California wildfires of 2017, against State Farm as well as the Company, ISO, and Xactware Solutions, Inc. Plaintiffs served a Second Amended Complaint on January 6, 2019. Like the First Amended Complaint, it alleges that defendants through the use of the Company’s 360Value product conspired to under-insure plaintiffs’ homes by issuing undervalued policies and underestimating the costs of rebuilding those homes. Plaintiffs claim that defendants violated federal antitrust law as well as California consumer protection law and common law. Defendants filed their motions to dismiss the Second Amended Complaint on March 8, 2019. On July 2, 2019, the Court granted those motions, dismissing various claims with leave to amend, and dismissing other claims with prejudice. Plaintiffs filed their Third Amended Complaint on August 1, 2019. As in the Second Amended Complaint plaintiffs claim in the Third Amended Complaint that defendants violated federal antitrust law as well as California consumer protection law and common law. Defendants filed their motions to dismiss the Third Amended Complaint on September 19, 2019. The motions were fully submitted on October 31, 2019 and oral argument, originally scheduled for November 27, 2019, has been postponed to February 13, 2020. At this time, it is not reasonably possible to determine the ultimate resolution of, or estimate the liability related to, this matter.

Basis of Presentation and Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2019

Accounting Policies [Abstract]

Basis of Presentation

The accompanying consolidated financial statements have been prepared on the basis of accounting principles generally accepted in the United States of America (“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, 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 equity awards granted, and assets and liabilities for pension and postretirement benefits. Actual results may ultimately differ from those estimates. Effective the first quarter of 2018, the operating segments of the Company are Insurance, Energy and Specialized Markets, and Financial Services. Previously, its operating segments were Decision Analytics and Risk Assessment. (See Note 19.). Certain reclassifications, including reflecting acquisition-related liabilities as a separate line item in 2019, have been made within the consolidated balance sheets, consolidated statements of cash flows and in the notes to conform to the respective 2019 presentation.

Intercompany Accounts and Transactions

The consolidated financial statements include the accounts of Verisk. All intercompany accounts and transactions have been eliminated.

Revenue Recognition, Deferred Revenues and Deferred Commissions

Revenue Recognition

The following describes the Company’s primary types of revenues and the applicable revenue recognition policies. The Company recognizes revenues through recurring and non-recurring long-term agreements (generally one to five years) for hosted subscriptions, advisory/consulting services, and for transactional solutions. Each of our reportable segments, Insurance, Energy and Specialized Markets, and Financial Services, has a portion of its revenue from more than one of these revenue types. The Company’s revenues are primarily derived from the sale of services where revenue is recognized when control of the promised services is transferred to customers in an amount that reflects the consideration that the Company expects to be entitled to in exchange for those services. Fees for services provided by the Company are non-refundable. Revenue is recognized net of applicable sales tax withholdings.

Hosted Subscriptions

The Company offers two forms of hosted subscriptions. The first and most prevalent form of hosted subscription is where customers access content only through the online portal (the "Hosted Subscription"). The Company grants a license to the customer to enter the online portal. The license is a contractual mechanism that allows the customer to access the online portal for a defined period of time. As the license alone does not provide utility to the customer, the customer has no contractual right to take possession of the online portal at any time, and the customer cannot engage another party to host the online portal and related content, it is not considered a functional license under Topic 606. The Company's promise to the customer is to provide continuous access to the online portal and to update the content throughout the subscription period. Hosted Subscription is a single performance obligation that represents a series of distinct services (daily access to the online portal and related content) that are substantially the same and that have the same pattern of transfer to the customer. The Company recognizes revenue for Hosted Subscriptions ratably over the subscription period on a straight-line basis as services are performed and continuous access to information in the online portal is provided over the entire term of the agreements.

The second form of hosted subscription is where customers have access to the Company's online portals combined with software content that is delivered via disk drive/download to the customer (“Hosted Subscription with Disk Drive/Download”) and is offered only on a limited basis. For this form of hosted subscription, the Company also grants the customer a license to enter the online portal as well as access the software content as needed and acts as the same contractual mechanism as described for Hosted Subscriptions. The Hosted Subscription with Disk Drive/Download works in such a manner that the customer gains significant benefit, functionality and overall utility only when the online portal and the software content are used together. The disk drive/download contains the models while the online portal contains the latest data and research which is updated throughout the subscription period. The models within the disk drive/download depend on the data and research contained within the online portal. The data and research within the online portal is only useful when the customer can utilize it within the models (e.g., queries, projections, etc.) so that they may use the most current information and alerts to forecast potential future losses. The software content is only sold together with the online portal to provide a highly interdependent and interrelated promise and therefore represents a single performance obligation. As the customer has no contractual right to take possession of the online portal at any time, and the customer cannot engage another party to host the online portal and related software content, it is not considered a functional license under Topic 606. The Company's promise to the customer is to deliver the disk drive/download, to provide continuous access to the online portal, and to update the software content throughout the subscription period. The Company recognizes revenue for Hosted Subscriptions with Disk Drive/Download ratably over the subscription period on a straight-line basis as services are performed and continuous access to information is provided over the entire term of the agreements.

Subscriptions are generally paid in advance of rendering services either quarterly or annually upon commencement of the subscription period, which is usually for one year and in most instances automatically renewed each year.

Advisory/Consulting Services

The Company provides certain discrete project based advisory/consulting services, which are recognized over time by measuring the progress toward complete satisfaction of the performance obligation, based on the input method of consulting hours worked; this aligns with the results achieved and value transferred to the customer. The hours consumed are most reflective of the measure of progress towards satisfying the performance obligation, as the resources hours worked directly tie to the progress of the services to be provided. In general, they are billed over the course of the project.

Transactional Solutions

Certain solutions are also paid for by customers on a transactional basis. The Company recognizes these revenues as the solutions are delivered or services performed at a point in time. In general, the customers are billed monthly at the end of each month.

Deferred CommissionsThe Company recognizes an asset for the incremental costs of obtaining a contract with a customer if it expects the benefit of those costs to be longer than one year. The Company has determined that certain sales incentive programs meet the requirements to be capitalized. The incremental costs of obtaining a contract with a customer, which primarily consist of sales commissions, are deferred and amortized over a useful life of five years that is consistent with the transfer to the customer the services to which the asset relates. The Company classifies deferred commissions as current or noncurrent based on the timing of expense recognition. The current and noncurrent portions of deferred commissions are included in prepaid expenses and other assets, respectively, in the consolidated balance sheets as of December 31, 2019. Amortization expense related to deferred commissions is computed on a straight-line basis over its estimated useful lives and included in "Selling, general and administrative" within the accompanying consolidated statements of operations.Deferred Revenues

The Company invoices its customers in annual, quarterly, monthly, or milestone installments. Amounts billed and/or collected in advance of services being provided are recorded as “Deferred revenues” and “Other noncurrent liabilities” in the accompanying consolidated balance sheets and are recognized as the services are performed, control is transferred to customers, and the applicable revenue recognition criteria is met.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are generally recorded at the invoiced amount. The allowance for doubtful accounts is estimated based on an analysis of the aging of the accounts receivable, historical write-offs, customer payment patterns, individual customer credit worthiness, current economic trends, and/or establishment of specific reserves for customers in adverse financial condition. The Company assesses the adequacy of the allowance for doubtful accounts on a quarterly basis.

Fixed Assets

Fixed assets and finite-lived intangibles are stated at cost less accumulated depreciation and amortization, which are computed on a straight-line basis over their estimated useful lives. Leasehold improvements are amortized over the shorter of the useful life of the asset or the lease term.

Finite-lived Intangible Assets

Fixed assets and finite-lived intangibles are stated at cost less accumulated depreciation and amortization, which are computed on a straight-line basis over their estimated useful lives. Leasehold improvements are amortized over the shorter of the useful life of the asset or the lease term.

Internal Use Software

The Company’s internal software development costs primarily relate to internal-use software. Such costs are capitalized in the application development stage in accordance with ASC 350-40, Internal-use Software ("ASC 350-40"). The Company also capitalizes software development costs upon the establishment of technological feasibility for a product in accordance with ASC 985-20, Software to be Sold, Leased, or Marketed (“ASC 985-20”). Software development costs are amortized on a straight-line basis.

Fixed Assets and Finite-Lived Intangible Assets Impairment

In accordance with ASC 360, Property, Plant & Equipment, whenever events or changes in circumstances indicate that the carrying amount of long-lived assets and finite-lived intangible assets may not be recoverable, the Company reviews its long-lived assets and finite-lived intangible assets for impairment by first comparing the carrying value of the assets to the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the assets. If the carrying value exceeds the sum of the assets’ undiscounted cash flows, the Company estimates and recognizes an impairment loss by taking the difference between the carrying value and fair value of the assets

Leases

The Company has operating and finance leases for corporate offices, data centers, and certain equipment that are accounted for under ASC 842. The leases have remaining lease terms ranging from one year to fourteen years, some of which include the options to extend the leases for up to twenty years, and some of which include the options to terminate the leases within one year. Extension and termination options are considered in the calculation of the right-of-use (“ROU”) assets and lease liabilities when the Company determines it is reasonably certain that it will exercise those options.

The Company determines if an arrangement is a lease at inception. The Company considers any contract where there is an identified asset and that it has the right to control the use of such asset in determining whether the contract contains a lease. A ROU asset represents the Company’s right to use an underlying asset for the lease term and the lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease ROU assets

and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s operating leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available on the adoption date in determining the present value of lease payments. The incremental borrowing rate was calculated by using the Company's credit rating on its publicly-traded U.S. unsecured bonds and estimating an appropriate credit rating for similar secured debt instruments. The Company's calculated credit rating on secured debt instruments determined the yield curve used. The Company calculated an implied spread and applied the spreads to the risk-free interest rates based on the yield of the U.S. Treasury zero coupon securities with a maturity equal to the remaining lease term in determining the borrowing rates for all operating leases. The operating lease ROU assets include any lease payments made prior to the rent commencement date and exclude lease incentives. Lease expense for lease payments are recognized on a straight-line basis over the lease term. Operating lease transactions are included in "Operating lease right-of-use assets, net", and "Operating lease liabilities", current and noncurrent, within the accompanying consolidated balance sheets. Finance leases are included in property and equipment under "Fixed assets, net", "Short-term debt and current portion of long-term debt", and "Long-term debt" within the accompanying consolidated balance sheets.

Fair Value of Financial and Non-financial Instruments

The Company follows the provisions of ASC 820-10, Fair Value Measurements (“ASC 820-10”), which defines fair value, establishes a framework for measuring fair value under U.S. GAAP and expands fair value measurement disclosures. The Company follows the provisions of ASC 820-10 for its financial assets and liabilities recognized or disclosed at fair value on a recurring basis. The Company follows the provisions of ASC 820-10 for its non-financial assets and liabilities recognized or disclosed at fair value.

Certain assets and liabilities of the Company are reported at fair value in the accompanying consolidated balance sheets. Such assets and liabilities include amounts for both financial and non-financial instruments. To increase consistency and comparability of assets and liabilities recorded at fair value, 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 is internally-developed, and considers risk premiums that a market participant would require.

Foreign Currency

The Company has determined local currencies are the functional currencies of the foreign operations. The assets and liabilities of foreign subsidiaries are translated at the period-end rate of exchange and statement of operations items are translated at the average rates prevailing during the year. The resulting translation adjustment is recorded as a component of “Accumulated other comprehensive losses” in the accompanying consolidated statements of changes in stockholders’ equity.

Stock Based Compensation

The Company follows ASC 718, Stock Compensation (“ASC 718”). Under ASC 718, stock based compensation cost is measured at the grant date, based on the fair value of the awards granted, and is recognized as expense over the requisite service period.

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 expected term for the stock options granted for a majority of the awards 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 the Company's historical daily closing prices over the most recent period that is commensurate with the expected term of the stock option awards. The expected dividend yield was based on the Company’s expected annual dividend rate on the date of grant.

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. Restricted stock generally has a service vesting period of four years and the Company recognizes the expense ratably over this service vesting period.

Performance share units (“PSU”) vest at the end of a three-year performance period, subject to the recipient’s continued service. Each PSU represents the right to receive one share of Verisk common stock and the ultimate realization is based on the Company’s achievement of certain market performance criteria. The Company determined the grant date fair value of PSUs with the assistance of a third-party valuation specialist and based on estimates provided by the Company. The valuation of the PSUs employed the Monte Carlo simulation model, which includes certain key assumptions that were applied to the Company and its peer group. Those key assumptions included valuation date stock price, expected volatility, correlation coefficients, risk-free rate of return, and expected dividend yield. The valuation date stock price is based on the dividend-adjusted closing price on the grant date. Expected

volatility is calculated using historical daily closing prices over a period that is commensurate with the length of the performance period. The correlation coefficients are based on the price data used to calculate the historical volatilities. The risk-free rate of return is based on the yield of U.S. Treasury zero coupon securities with a maturity equal to the length of the performance period. The expected dividend yield was based on the Company and its peer group’s expected dividend rate over the performance period.

The Company estimates expected forfeitures of equity awards at the date of grant and recognizes compensation expense only for those awards expected to vest. The forfeiture assumption is ultimately adjusted to the actual forfeiture rate. Estimated forfeiture is ultimately adjusted to actual forfeiture. Changes in the forfeiture assumptions may impact the total amount of expense ultimately recognized, as well as the timing of expense recognized over the requisite service period.

Excess tax benefit from exercised stock options, lapsing of restricted stock and PSUs is recorded as an income tax benefit in the accompanying consolidated statements of operations. This tax benefit is calculated as the excess of the intrinsic value of options exercised and of the market value of restricted stock lapsed over the compensation recognized for financial reporting purposes.

Research and Development Costs

Research and development costs, which are primarily related to personnel and related overhead costs incurred in developing new services for customers, are expensed as incurred.

Advertising Costs

Advertising costs, which are primarily associated with promoting the Company’s brand, names and solutions provided, are expensed as incurred.

Income Taxes

The Company accounts for income taxes under the asset and liability method under ASC 740, Income Taxes (“ASC 740”), which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.

Deferred tax assets are recorded to the extent these assets are more likely than not to be realized. In making such determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies, and recent financial operations. Valuation allowances are recognized to reduce deferred tax assets if it is determined to be more likely than not that all or some of the potential deferred tax assets will not be realized.

The Company follows ASC 740-10, Income Taxes (“ASC 740-10”), which clarifies the accounting for uncertainty in income taxes recognized in the financial statements. ASC 740-10 provides that a tax benefit from an uncertain tax position may be recognized based on the technical merits when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes. Income tax positions must meet a more likely than not recognition threshold in accordance with ASC 740-10. This standard also provides guidance on measurement, derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition.

The Company recognizes interest and penalties related to unrecognized tax benefits within the income tax expense line in the accompanying consolidated statements of operations. Accrued interest and penalties are included within “Other liabilities” on the accompanying consolidated balance sheets.

Earnings Per Share

Basic and diluted earnings per share (“EPS”) are determined in accordance with ASC 260, Earnings per Share, which specifies the computation, presentation and disclosure requirements for EPS. Basic EPS excludes all dilutive common stock equivalents. It is based upon the weighted average number of common shares outstanding during the period. Diluted EPS, as calculated using the treasury stock method, reflects the potential dilution that would occur if the Company’s dilutive outstanding stock options and stock awards were issued.

Pension and Postretirement Benefits

The Company accounts for its pension and postretirement benefits under ASC 715, Compensation — Retirement Benefits (“ASC 715”). ASC 715 requires the recognition of the funded status of a benefit plan in the balance sheet, the recognition in other comprehensive income (loss) of gains or losses and prior service costs arising during the period, but which are not included as components of periodic benefit cost or credit, and the measurement of defined benefit plan assets and obligations as of the balance sheet date. The Company utilizes a valuation date of December 31.

Product Warranty Obligations

The Company provides warranty coverage for certain of its solutions. The Company recognizes a product warranty obligation when claims are probable and can be reasonably estimated. As of December 31, 2019 and 2018, product warranty obligations were not material.

In the ordinary course of business, the Company enters into numerous agreements that contain standard indemnities whereby the Company indemnifies another party for breaches of confidentiality, infringement of intellectual property or gross negligence. Such indemnifications are primarily granted under licensing of computer software. Most agreements contain provisions to limit the maximum potential amount of future payments that the Company could be required to make under these indemnifications; however, the Company is not able to develop an estimate of the maximum potential amount of future payments to be made under these indemnifications as the triggering events are not subject to predictability.

Loss Contingencies

The Company accrues for costs relating to litigation, claims and other contingent matters when such liabilities become probable and reasonably estimable. Such estimates are based on management’s judgment. Actual amounts paid may differ from amounts estimated, and such differences will be charged to operations in the period in which the final determination of the liability is made.

Goodwill

Goodwill represents the excess of acquisition costs over the fair value of tangible net assets and identifiable intangible assets of the businesses acquired. Goodwill and intangible assets deemed to have indefinite lives are not amortized. Intangible assets determined to have finite lives are amortized over their useful lives. 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. The Company completed the required annual impairment test as of June 30, 2019, which resulted in no impairment of goodwill in 2019. This test 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 the goodwill.

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 reportable 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 CEO is identified as the CODM as defined by ASC 280-10.

The Company previously reported results based on its two operating segments, Decision Analytics and Risk Assessment. During the first quarter of 2018, the CODM changed how he makes operating decisions, assesses the performance of the business, and allocates resources in a manner that caused its operating segments to change. Consequently, effective as of the first quarter of 2018, the operating segments of the Company are based on three vertical markets it serves: Insurance, Energy and Specialized Markets, and Financial Services. These three operating segments are also the Company's reportable segments, which have been recast to reflect the new segments for the year ended December 31, 2017.

Each of the Company's reportable segments, Insurance, Energy and Specialized Markets, and Financial Services has a portion of its revenue from more than one of the three revenue types described within the revenue recognition policy within Note 2. Basis of Presentation and Summary of Significant Accounting Policies. Below is the overview of the solutions offered within each reportable segment.

Insurance: 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, which are accessed via a hosted platform. The Company also develops solutions that its customers use to analyze key processes in managing risk. 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, ranging from hurricanes to earthquakes. The Company develops catastrophe and extreme event models and offers solutions covering natural and man-made risks, including acts of terrorism. The Company further develops solutions that allow customers to quantify costs after loss events occur. The Company's multitier, multispectral terrestrial imagery and data acquisition, processing, analytics, and distribution system using the remote sensing and machine learning technologies help gather, store, process, and deliver geographic and spatially referenced information that supports uses in many markets. Additionally, the Company offers fraud-detection solutions including review of data on claim histories, analysis of claims to find emerging patterns of fraud, and identification of suspicious claims in the insurance sector. The Company’s underwriting & rating, insurance anti-fraud claims, catastrophe modeling, and loss quantification are included in this segment.

Energy and Specialized Markets: The Company is a leading provider of data analytics via hosted platform for the global energy, chemicals, and metals and mining industries. Its research and consulting solutions focus on exploration strategies and screening, asset development and acquisition, commodity markets, and corporate analysis in the areas of business environment, business improvement, business strategies, commercial advisory, and transaction support. The Company gathers and manages proprietary information, insight, and analysis on oil and gas fields, mines, refineries and other assets across the interconnected global energy sectors to advise customers in making asset investment and portfolio allocation decisions. The Company also helps businesses and governments better anticipate and manage climate and weather-related risks. The Company's analytical tools measure and observe environmental properties and translate those

measurements into actionable information based on customer needs. In addition, the Company provides market and cost intelligence to energy companies to optimize financial results. The Company further offers a suite of data and information services that enable improved compliance with global Environmental Health and Safety requirements related to the safe manufacturing, distribution, transportation, usage, and disposal of chemicals and products. The Company’s energy business, environmental health and safety services and, weather risk solutions are included in this segment.

Financial Services: The Company maintains a bank account consortia to provide competitive benchmarking, decisioning algorithms, business intelligence, and customized analytic services that help financial institutions, payment networks and processors, alternative lenders, regulators and merchants make better strategy, marketing, and risk decisions. Customers apply the Company's solutions in the areas of tailored data management and media effectiveness that include business intelligence platforms, profile views, mobile data solutions, enterprise database services, and fraud risk scoring algorithms for marketing, fraud, and risk mitigation. In addition, the Company's bankruptcy management solutions assist creditors, debt servicing businesses and credit services to enhance regulatory compliance by eliminating stay violation and portfolio valuation risk.

⁽²⁾	The pooled separate accounts invest in domestic and foreign stocks, bonds and mutual funds. The fair values of these stocks, bonds and mutual funds are publicly quoted and are used in determining the NAV of the pooled separate account, which is not publicly quoted.


⁽³⁾	Investments for which readily determinable prices do not exist are valued by the General Partner using either the market or income approach. In establishing the estimated fair value of investments, including those without readily determinable values, the General Partner assumes a reasonable period of time for liquidation of the investment, and takes into

consideration the financial condition and operating results of the underlying portfolio company, nature of investment, restrictions on marketability, holding period, market conditions, foreign currency exposures, and other factors the General Partner deems appropriate.

⁽⁴⁾

The fund invested in the U.S. government, its agencies or instrumentalities or securities that are rated AAA by S&P, AAA by Fitch, or Aaa by Moody’s, including but not limited to mortgage securities such as agency and non-agency collateralized mortgage obligations, and other obligations that are secured by mortgages or mortgage backed securities, and valued at the closing price reported in the active market.

⁽⁵⁾

The funds invested in common stocks and other equity securities issued by domestic and foreign real estate companies, including real estate investment trusts ("REIT") and similar REIT-like entities.
