Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES Description of Business Unless the context otherwise requires, the terms "Verint", "we", "us", and "our" in these notes to consolidated financial statements refer to Verint Systems Inc. and its consolidated subsidiaries. Verint is a global leader in Actionable Intelligence solutions. Actionable Intelligence is a necessity in a dynamic world of massive information growth because it empowers organizations with crucial insights and enables decision makers to anticipate, respond, and take action. With Verint solutions and value-added services, organizations of all sizes and across many industries can make more informed, timely, and effective decisions.

Headquartered in Melville, New York, we support our customers around the globe directly and with an extensive network of selling and support partners. Preparation of Condensed Consolidated Financial Statements The condensed consolidated financial statements included herein have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and on the same basis as the audited consolidated financial statements included in our Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission ("SEC") for the year ended January 31, 2017. The condensed consolidated statements of operations, comprehensive (loss) income, stockholders’ equity, and cash flows for the periods ended July 31, 2017 and 2016, and the condensed consolidated balance sheet as of July 31, 2017, are not audited but reflect all adjustments that are of a normal recurring nature and that are considered necessary for a fair presentation of the results for the periods shown. The condensed consolidated balance sheet as of January 31, 2017 is derived from the audited consolidated financial statements presented in our Annual Report on Form 10-K for the year ended January 31, 2017. Certain information and disclosures normally included in annual consolidated financial statements have been omitted pursuant to the rules and regulations of the SEC. Because the condensed consolidated interim financial statements do not include all of the information and disclosures required by GAAP for a complete set of financial statements, they should be read in conjunction with the audited consolidated financial statements and notes included in our Annual Report on Form 10-K filed with the SEC for the year ended January 31, 2017. The results for interim periods are not necessarily indicative of a full year’s results. Recasting of Prior Period Segment Information Through July 31, 2016, we were organized and had reported our operating results in three operating segments. In August 2016, we reorganized into two businesses and now report our results in two operating segments, as further discussed in Note 14, "Segment Information". Comparative segment financial information for prior periods appearing in Note 5, "Intangible Assets and Goodwill" and Note 14, "Segment Information", has been recast to conform to this revised segment structure. Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of Verint Systems Inc., our wholly owned or otherwise controlled subsidiaries, and a joint venture in which we hold a 50% equity interest. The joint venture is a variable interest entity in which we are the primary beneficiary. Noncontrolling interests in less than wholly owned subsidiaries are reflected within stockholders’ equity on our condensed consolidated balance sheet, but separately from our stockholders' equity. We hold an option to acquire the noncontrolling interests in two majority owned subsidiaries and we account for the option as an in-substance investment in the noncontrolling common stock of each such subsidiary. We include the fair value of the option within other liabilities and do not recognize noncontrolling interests in these subsidiaries. We include the results of operations of acquired companies from the date of acquisition. All significant intercompany transactions and balances are eliminated. Investments in companies in which we have less than a 20% ownership interest and cannot exercise significant influence are accounted for at cost. Use of Estimates The preparation of financial statements in conformity with GAAP requires our management to make estimates and assumptions, which may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Accounts Receivable, Net Accounts receivable, net, includes unbilled accounts receivable on arrangements recognized under contract accounting methods, representing revenue recognized on contracts for which billing will occur in subsequent periods, in accordance with the terms of the contracts. Unbilled accounts receivable on such contracts were $62.0 million and $39.7 million at July 31, 2017 and January 31, 2017, respectively. Under most contracts, unbilled accounts receivable are typically billed and collected within one year of revenue recognition. However, as of July 31, 2017, we have unbilled accounts receivable on certain complex projects with a long-standing customer for which the underlying billing milestones are still in progress and have remained unbilled for periods in excess of one year, and in some cases, for several years. Unbilled accounts receivable from this customer have declined significantly over the past year. We have no history of uncollectible accounts with this customer and believe that collection of all unbilled amounts is reasonably assured. We expect billing and collection of all unbilled accounts receivable from this customer to occur within the next twelve months. Significant Accounting Policies Our significant accounting policies are described in Note 1 to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended January 31, 2017. There were no material changes to our significant accounting policies during the six months ended July 31, 2017. Recent Accounting Pronouncements New Accounting Pronouncements Recently Adopted In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-09, Compensation—Stock Compensation (Topic 718), which amends the accounting for stock-based compensation and requires excess tax benefits and deficiencies to be recognized as a component of income tax expense rather than stockholders' equity. This guidance also requires excess tax benefits to be presented as an operating activity on the consolidated statements of cash flows and allows an entity to make an accounting policy election to either estimate expected forfeitures or to account for them as they occur. ASU No. 2016-09 was effective for us on February 1, 2017. The adoption did not result in a cumulative-effect adjustment to retained earnings, and in accordance with the new guidance, we recorded certain tax effects from stock-based compensation awards as components of the benefit for income taxes for the three and six months ended July 31, 2017, whereas such tax effects were previously recognized in stockholders’ equity. These tax effects were not material for the three and six months ended July 31, 2017. Our accounting for forfeitures of stock-based compensation awards has not changed because we have elected to continue our current policy of estimating expected forfeitures. The effects of adopting the other provisions of ASU No. 2016-09 were not material to our condensed consolidated financial statements. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which requires entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The new guidance is effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted as of the beginning of an annual reporting period. The new standard must be adopted using a modified retrospective transition method, with the cumulative effect recognized as of the date of initial adoption. We have elected to early adopt this standard as of February 1, 2017, resulting in a $0.9 million cumulative charge to retained deficit, a $1.3 million reduction to other current assets, and a $0.4 million increase in other assets. New Accounting Pronouncements Not Yet Effective In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities. This update better aligns risk management activities and financial reporting for hedging relationships, simplifies hedge accounting requirements, and improves disclosures of hedging arrangements. ASU No. 2017-12 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. We are currently reviewing this standard to assess the impact on our condensed consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, and ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment. ASU No. 2017-01 clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those periods. While we are still assessing the impact of this standard, we do not believe that the adoption of this guidance will have a material impact on our condensed consolidated financial statements. ASU No. 2017-04 eliminates Step 2 of the goodwill impairment test and requires a goodwill impairment to be measured as the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of its goodwill. The ASU is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. While we are still assessing the impact of this standard, we do not believe that the adoption of this guidance will have a material impact on our condensed consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This update requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This update also requires an entity to disclose the nature of restrictions on its cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. ASU No. 2016-18 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years with early adoption permitted, including adoption in an interim period. We typically have restrictions on certain amounts of cash and cash equivalents, primarily consisting of amounts used to secure bank guarantees in connection with sales contract performance obligations, and expect to continue to have similar restrictions in the future. We currently report changes in such restricted amounts as cash flows from investing activities on our consolidated statement of cash flows. This standard will change that presentation. We are currently reviewing this standard to assess other potential impacts on our condensed consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which provides guidance with the intent of reducing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. ASU No. 2016-15 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years with early adoption permitted, including adoption in an interim period. We are currently reviewing this standard to assess the impact on our condensed consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326). This new standard changes the impairment model for most financial assets and certain other instruments. Entities will be required to use a model that will result in the earlier recognition of allowances for losses for trade and other receivables, held-to-maturity debt securities, loans, and other instruments. For available-for-sale debt securities with unrealized losses, the losses will be recognized as allowances rather than as reductions in the amortized cost of the securities. The new standard is effective for annual periods, and for interim periods within those annual periods, beginning after December 15, 2019, with early adoption permitted. We are currently reviewing this standard to assess the impact on our condensed consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which will require lessees to recognize assets and liabilities for leases with lease terms of more than 12 months. Consistent with current GAAP, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. However, unlike current GAAP, which requires only capital leases to be recognized on the balance sheet, the new guidance will require both types of leases to be recognized on the balance sheet. The new guidance is effective for all periods beginning after December 15, 2018 and we are currently evaluating the effects that the adoption of ASU No. 2016-02 will have on our consolidated financial statements, but anticipate that the new guidance will significantly impact our condensed consolidated financial statements given our significant number of leases. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). ASU No. 2014-09 supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific revenue recognition guidance throughout the Industry Topics of the Accounting Standards Codification. Additionally, this update supersedes some cost guidance included in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. As originally issued, this guidance was effective for interim and annual reporting periods beginning after December 15, 2016, and early adoption was not permitted. In July 2015, the FASB deferred the effective date by one year, to interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, but not before the original effective date of December 15, 2016. The standard allows entities to apply the standard retrospectively to each prior reporting period presented (“full retrospective adoption”) or retrospectively with the cumulative effect of initially applying the standard recognized at the date of initial application (“modified retrospective adoption”). We currently expect to adopt ASU No. 2014-09 using the modified retrospective option. We are continuing to review the impacts of adopting ASU No. 2014-09 to our condensed consolidated financial statements. Based upon our preliminary assessments, we currently do not expect the new standard to materially impact the amount or timing of the majority of revenue recognized in our condensed consolidated financial statements. We are still assessing the impact on the timing of revenue recognized under certain contracts under which customized solutions are delivered over extended periods of time. In addition, the timing of cost of revenue recognition for certain customer contracts requiring significant customization will change, because unlike current guidance, the new guidance precludes the deferral of costs simply to obtain an even profit margin over the contract term. We are also assessing the new standard’s requirement to capitalize costs associated with obtaining customer contracts, including commission payments, which are currently expensed as incurred. Under the new standard, these costs will be deferred on our consolidated balance sheet. We are evaluating the period over which to amortize these capitalized costs. In addition, for sales transactions that have been billed, but for which the recognition of revenue has been deferred and the related account receivable has not been collected, we currently do not recognize deferred revenue or the related accounts receivable on our consolidated balance sheet. Under the new standard, we will record accounts receivable and related contract liabilities for noncancelable contracts with customers when the right to consideration is unconditional, which we currently expect will result in increases in accounts receivable and contract liabilities (currently presented as deferred revenue) on our consolidated balance sheet, compared to our current presentation. Our preliminary assessments of the impacts to our condensed consolidated financial statements of adopting this new standard are subject to change.

NET LOSS PER COMMON SHARE ATTRIBUTABLE TO VERINT SYSTEMS INC.

The following table summarizes the calculation of basic and diluted net loss per common share attributable to Verint Systems Inc. for the three and six months ended July 31, 2017 and 2016:



	Three Months Ended July 31,						Six Months Ended July 31,
(in thousands, except per share amounts)	2017			2016			2017			2016

Dilutive effect of 1.50% convertible senior notes	—			—			—			—
Dilutive effect of warrants	—			—			—			—
Diluted	63,185			62,668			62,838			62,463
Net loss per common share attributable to Verint Systems Inc.:
Basic	$	(0.10	)	$	(0.19	)	$	(0.42	)	$	(0.47	)
Diluted	$	(0.10	)	$	(0.19	)	$	(0.42	)	$	(0.47	)

We excluded the following weighted-average potential common shares from the calculations of diluted net loss per common share during the applicable periods because their inclusion would have been anti-dilutive:



	Three Months Ended July 31,		Six Months Ended July 31,
(in thousands)	2017	2016	2017	2016
Common shares excluded from calculation:
Stock options and restricted stock-based awards	1,282	1,035	1,243	1,276
1.50% convertible senior notes	6,205	6,205	6,205	6,205
Warrants	6,205	6,205	6,205	6,205

In periods for which we report a net loss attributable to Verint Systems Inc., basic net loss per common share and diluted net loss per common share are identical since the effect of all potential common shares is anti-dilutive and therefore excluded.

Our 1.50% convertible senior notes ("Notes") will not impact the calculation of diluted net income per share unless the average price of our common stock, as calculated in accordance with the terms of the indenture governing the Notes, exceeds the conversion price of $64.46 per share. Likewise, diluted net income per share will not include any effect from the Warrants (as defined in Note 6, "Long-Term Debt") unless the average price of our common stock, as calculated under the terms of the Warrants, exceeds the exercise price of $75.00 per share.

Our Note Hedges (as defined in Note 6, "Long-Term Debt") do not impact the calculation of diluted net income per share under the treasury stock method, because their effect would be anti-dilutive. However, in the event of an actual conversion of any or all of the Notes, the common shares that would be delivered to us under the Note Hedges would neutralize the dilutive effect of the common shares that we would issue under the Notes. As a result, actual conversion of any or all of the Notes would not increase our outstanding common stock. Up to 6,205,000 common shares could be issued upon exercise of the Warrants. Further details regarding the Notes, Note Hedges, and the Warrants appear in Note 6, "Long-Term Debt".

Business Combinations [Abstract]

BUSINESS COMBINATIONS

Six Months Ended July 31, 2017

During the six months ended July 31, 2017, we completed two transactions in our Customer Engagement segment, one of which retained a noncontrolling interest, and one acquisition in our Cyber Intelligence segment, all of which qualified as business combinations. These business combinations were not material to our condensed consolidated financial statements individually or in the aggregate.

Year Ended January 31, 2017

Contact Solutions, LLC

On February 19, 2016, we completed the acquisition of Contact Solutions, LLC ("Contact Solutions"), a provider of real-time, contextual self-service solutions, based in Reston, Virginia. The purchase price consisted of $66.9 million of cash paid at closing, and a $2.5 million post-closing purchase price adjustment based upon a determination of Contact Solutions' acquisition-date working capital, which was paid during the three months ended July 31, 2016. The cash paid for this acquisition was funded with cash on hand.

The purchase price for Contact Solutions was allocated to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values on the acquisition dates, with the remaining unallocated purchase price recorded as goodwill. The fair value assigned to identifiable intangible assets acquired were determined primarily by using the income approach, which discounts expected future cash flows to present value using estimates and assumptions determined by management.

Among the factors contributing to the recognition of goodwill as a component of the Contact Solutions purchase price allocation were synergies in products and technologies, and the addition of a skilled, assembled workforce. This goodwill has been assigned to our Customer Engagement segment and is deductible for income tax purposes.

In connection with the purchase price allocation for Contact Solutions, the estimated fair value of undelivered performance obligations under customer contracts assumed in the acquisition was determined utilizing a cost build-up approach. The cost build-up approach calculates fair value by estimating the costs required to fulfill the obligations plus a reasonable profit margin, which approximates the amount that we believe would be required to pay a third party to assume the performance obligations. The estimated costs to fulfill the performance obligations were based on the historical direct costs for delivering similar services. As a result, in allocating the purchase price, we recorded $0.6 million of current and long-term deferred revenue, representing the estimated fair value of undelivered performance obligations for which payment had been received, which will be recognized as revenue as the underlying performance obligations are delivered. For undelivered performance obligations for which payment had not yet been received, we recorded a $2.9 million asset as a component of the purchase price allocation, representing the estimated fair value of these obligations, $1.2 million of which was included within prepaid expenses and other current assets, and $1.7 million of which was included in other assets. We are amortizing this asset over the underlying delivery periods, which adjusts the revenue we recognize for providing these services to its estimated fair value.

Transaction and related costs directly related to the acquisition of Contact Solutions, consisting primarily of professional fees and integration expenses, were not material for the three and six months ended July 31, 2017, and $0.3 million and $0.6 million for the three and six months ended July 31, 2016, respectively, and were expensed as incurred in selling, general, and administrative expenses.

OpinionLab, Inc.

On November 16, 2016, we completed the acquisition of all of the outstanding shares of Chicago, Illinois-based OpinionLab, Inc. ("OpinionLab"), a leading SaaS provider of omnichannel Voice of Customer (“VoC”) feedback solutions which help organizations collect, understand, and leverage customer insights, helping drive smarter, real-time business action.

The purchase price consisted of $56.4 million of cash paid at the closing, funded from cash on hand, partially offset by $6.4 million of OpinionLab's cash received in the acquisition, resulting in net cash consideration at closing of $50.0 million, and we agreed to pay potential additional future cash consideration of up to $28.0 million, contingent upon the achievement of certain performance targets over the period from closing through January 31, 2021, the acquisition date fair value of which was estimated to be $15.0 million. The purchase price is subject to customary purchase price adjustments related to the final determination of OpinionLab's cash, net working capital, transaction expenses, and taxes as of November 16, 2016. The acquired business has been integrated into our Customer Engagement operating segment.

The purchase price for OpinionLab was allocated to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values on the acquisition dates, with the remaining unallocated purchase price recorded as goodwill. The fair value assigned to identifiable intangible assets acquired were determined primarily by using the income approach, which discounts expected future cash flows to present value using estimates and assumptions determined by management.

Among the factors contributing to the recognition of goodwill as a component of the OpinionLab purchase price allocation were synergies in products and technologies, and the addition of a skilled, assembled workforce. This goodwill has been assigned to our Customer Engagement segment and is not deductible for income tax purposes.

In connection with the purchase price allocation for OpinionLab, the estimated fair value of undelivered performance obligations under customer contracts assumed in the acquisition was determined utilizing a cost build-up approach. The cost build-up approach calculates fair value by estimating the costs required to fulfill the obligations plus a reasonable profit margin, which approximates the amount that we believe would be required to pay a third party to assume the performance obligations. The estimated costs to fulfill the performance obligations were based on the historical direct costs for delivering similar services. As a result, in allocating the purchase price, we recorded $3.1 million of current and long-term deferred revenue, representing the estimated fair value of undelivered performance obligations for which payment had been received, which will be recognized as revenue as the underlying performance obligations are delivered. For undelivered performance obligations for which payment had not yet been received, we recorded a $5.4 million asset as a component of the purchase price allocation, representing the estimated fair value of these obligations, $3.4 million of which was included within prepaid expenses and other current assets, and $2.0 million of which was included in other assets. We are amortizing this asset over the underlying delivery periods, which adjusts the revenue we recognize for providing these services to its estimated fair value.

The purchase price allocation for OpinionLab has been prepared on a preliminary basis and changes to the allocation may occur as additional information becomes available during the measurement period (up to one year from the acquisition date). Fair values still under review include values assigned to identifiable intangible assets and certain pre-acquisition loss contingencies.

Transaction and related costs directly related to the acquisition of OpinionLab, consisting primarily of professional fees and integration expenses, were and $0.3 million and $0.5 million for the three and six months ended July 31, 2017, respectively and were expensed as incurred within selling, general and administrative expenses. Such costs were not material for the three and six months ended July 31, 2016.

The following table sets forth the components and the allocations of the purchase prices for our acquisitions of Contact Solutions and OpinionLab.



(in thousands)	Contact Solutions			OpinionLab
Components of Purchase Price:
Cash paid at closing	$	66,915		$	56,355

Total identifiable intangible assets	33,500			31,300
Goodwill	22,113			41,025
Total purchase price allocation	$	69,433		$	71,355

For the acquisition of Contact Solutions, the acquired customer relationships, developed technology, and trademarks and trade names were assigned estimated useful lives of ten years, four years, and five years, respectively, the weighted average of which is approximately 7.3 years.

For the acquisition of OpinionLab, the acquired customer relationships, developed technology, and trademarks and trade names were assigned estimated useful lives of ten years, six years, and four years, respectively, the weighted average of which is approximately 8.3 years.

The weighted-average estimated useful life of all finite-lived identifiable intangible assets acquired during the year ended January 31, 2017 is 7.8 years.

The acquired identifiable intangible assets are being amortized on a straight-line basis, which we believe approximates the pattern in which the assets are utilized, over their estimated useful lives.

Other Business Combinations

During the year ended January 31, 2017, in addition to the acquisitions of Contact Solutions and OpinionLab, we completed two transactions in our Customer Engagement segment which qualified as business combinations. These business combinations were not material to our condensed consolidated financial statements individually or in the aggregate.

Other Business Combination Information

The acquisition date fair values of contingent consideration obligations associated with business combinations are estimated based on probability adjusted present values of the consideration expected to be transferred using significant inputs that are not observable in the market. Key assumptions used in these estimates include probability assessments with respect to the likelihood of achieving the performance targets and discount rates consistent with the level of risk of achievement. At each reporting date, we revalue the contingent consideration obligations to their fair values and record increases and decreases in fair value within selling, general and administrative expenses in our condensed consolidated statements of operations. Changes in the fair value of the contingent consideration obligations result from changes in discount periods and rates, and changes in probability assumptions with respect to the likelihood of achieving the performance targets.

In connection with immaterial business combinations that closed during the six months ended July 31, 2017, we recorded contingent consideration obligations with a combined fair value of $3.7 million.

For the three months ended July 31, 2017 and 2016, we recorded $0.6 million and $1.8 million, respectively, and for the six months ended July 31, 2017 and 2016, we recorded $2.9 million and $2.6 million, respectively, within selling, general and administrative expenses for changes in the fair values of contingent consideration obligations associated with business combinations. The aggregate fair values of the remaining contingent consideration obligations associated with business combinations was $50.1 million at July 31, 2017, of which $13.2 million was recorded within accrued expenses and other current liabilities, and $36.9 million was recorded within other liabilities.

Payments of contingent consideration earned under these agreements were $6.9 million and $0.4 million for the three months ended July 31, 2017 and 2016, respectively, and $9.3 million and $3.3 million for the six months ended July 31, 2017 and 2016, respectively.

1.50% Convertible Senior Notes

On June 18, 2014, we issued $400.0 million in aggregate principal amount of 1.50% convertible senior notes due June 1, 2021 ("Notes"), unless earlier converted by the holders pursuant to their terms. Net proceeds from the Notes after underwriting discounts were $391.9 million. The Notes pay interest in cash semiannually in arrears at a rate of 1.50% per annum.

The Notes were issued concurrently with our public issuance of 5,750,000 shares of common stock, the majority of the

combined net proceeds of which were used to partially repay certain indebtedness under our Prior Credit Agreement, as further

described below.

The Notes are unsecured and are convertible into, at our election, cash, shares of common stock, or a combination of both, subject to satisfaction of specified conditions and during specified periods. If converted, we currently intend to pay cash in respect of the principal amount of the Notes.

The Notes have a conversion rate of 15.5129 shares of common stock per $1,000 principal amount of Notes, which represents an effective conversion price of approximately $64.46 per share of common stock and would result in the issuance of approximately 6,205,000 shares if all of the Notes were converted. The conversion rate has not changed since issuance of the Notes, although throughout the term of the Notes, the conversion rate may be adjusted upon the occurrence of certain events.

On or after December 1, 2020 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may surrender their Notes for conversion regardless of whether any of the other specified conditions for conversion have been satisfied.

As of July 31, 2017, the Notes were not convertible.

In accordance with accounting guidance for convertible debt with a cash conversion option, we separately accounted for the debt and equity components of the Notes in a manner that reflected our estimated nonconvertible debt borrowing rate. We estimated the debt and equity components of the Notes to be $319.9 million and $80.1 million, respectively, at the issuance date, assuming a 5.00% non-convertible borrowing rate. The equity component was recorded as an increase to additional paid-in capital. The excess of the principal amount of the debt component over its carrying amount (the "debt discount") is being amortized as interest expense over the term of the Notes using the effective interest method. The equity component is not remeasured as long as it continues to meet the conditions for equity classification.

Issuance costs attributable to the debt component of the Notes were netted against long-term debt and are being amortized as interest expense over the term of the Notes, and issuance costs attributable to the equity component were netted with the equity component in additional paid-in capital. The carrying amount of the equity component, net of issuance costs, was $78.2 million at July 31, 2017.

As of July 31, 2017, the carrying value of the debt component was $347.8 million, which is net of unamortized debt discount and issuance costs of $47.7 million and $4.5 million, respectively. Including the impact of the debt discount and related deferred debt issuance costs, the effective interest rate on the Notes was approximately 5.29% at July 31, 2017.

Based on the closing market price of our common stock on July 31, 2017, the if-converted value of the Notes was less than the aggregate principal amount of the Notes.

Note Hedges and Warrants

Concurrently with the issuance of the Notes, we entered into convertible note hedge transactions (the "Note Hedges") and sold warrants (the "Warrants"). The combination of the Note Hedges and the Warrants serves to increase the effective initial conversion price for the Notes to $75.00 per share. The Note Hedges and Warrants are each separate instruments from the Notes.

Note Hedges

Pursuant to the Note Hedges, we purchased call options on our common stock, under which we have the right to acquire from the counterparties up to approximately 6,205,000 shares of our common stock, subject to customary anti-dilution adjustments, at a price of $64.46, which equals the initial conversion price of the Notes. Our exercise rights under the Note Hedges generally trigger upon conversion of the Notes and the Note Hedges terminate upon maturity of the Notes, or the first day the Notes are no longer outstanding. The Note Hedges may be settled in cash, shares of our common stock, or a combination thereof, at our option, and are intended to reduce our exposure to potential dilution upon conversion of the Notes. We paid $60.8 million for the Note Hedges, which was recorded as a reduction to additional paid-in capital. As of July 31, 2017, we had not purchased any shares of our common stock under the Note Hedges.

Warrants

We sold the Warrants to several counterparties. The Warrants provide the counterparties rights to acquire from us up to approximately 6,205,000 shares of our common stock at a price of $75.00 per share. The Warrants expire incrementally on a series of expiration dates beginning in August 2021. At expiration, if the market price per share of our common stock exceeds the strike price of the Warrants, we will be obligated to issue shares of our common stock having a value equal to such excess. The Warrants could have a dilutive effect on net income per share to the extent that the market value of our common stock exceeds the strike price of the Warrants. Proceeds from the sale of the Warrants were $45.2 million and were recorded as additional paid-in capital. As of July 31, 2017, no Warrants had been exercised and all Warrants remained outstanding.

The Note Hedges and Warrants both meet the requirements for classification within stockholders’ equity, and their respective fair values are not remeasured and adjusted as long as these instruments continue to qualify for stockholders’ equity classification.

Credit Agreements

Prior Credit Agreement

In April 2011, we entered into a credit agreement with certain lenders, which was amended and restated in March 2013, and further amended in February, March, and June 2014 (the "Prior Credit Agreement"). The Prior Credit Agreement, as amended and restated, provided for senior secured credit facilities, comprised of $943.5 million of term loans, of which $300.0 million was borrowed in February 2014 and $643.5 million was borrowed in March 2014 (together, the "2014 Term Loans"), the outstanding portion of which was scheduled to mature in September 2019, and a $300.0 million revolving credit facility (the "Prior Revolving Credit Facility"), scheduled to mature in September 2018, subject to increase and reduction from time to time, as described in the Prior Credit Agreement.

In June 2014, we utilized the majority of the combined net proceeds from the issuance of the Notes and the concurrent issuance of 5,750,000 shares of common stock to retire $530.0 million of the 2014 Term Loans and all $106.0 million of then-outstanding borrowings under the Prior Revolving Credit Facility.

The 2014 Term Loans incurred interest at our option at either a base rate plus a margin of 1.75% or an Adjusted LIBOR Rate, as defined in the Prior Credit Agreement, plus a margin of 2.75%.

2017 Credit Agreement

On June 29, 2017, we entered into a new Credit Agreement (the “2017 Credit Agreement”) with certain lenders and terminated the Prior Credit Agreement.

The 2017 Credit Agreement provides for $725.0 million of senior secured credit facilities, comprised of a $425.0 million term loan maturing on June 29, 2024 (the “2017 Term Loan”) and a $300.0 million revolving credit facility maturing on June 29, 2022 (the “2017 Revolving Credit Facility”), subject to increase and reduction from time to time according to the terms of the 2017 Credit Agreement. The maturity dates of the 2017 Term Loan and 2017 Revolving Credit Facility will be accelerated to March 1, 2021 if on such date any Notes remain outstanding.

The majority of the proceeds from the 2017 Term Loan were used to repay all $406.9 million owed under the 2014 Term Loans at June 29, 2017 upon termination of the Prior Credit Agreement. There were no borrowings under the Prior Revolving Credit Facility at June 29, 2017.

The 2017 Term Loan was subject to an original issuance discount of approximately $0.5 million. This discount is being amortized as interest expense over the term of the 2017 Term Loan using the effective interest method.

Interest rates on loans under the 2017 Credit Agreement are periodically reset, at our option, at either a Eurodollar Rate or an ABR rate (each as defined in the 2017 Credit Agreement), plus in each case a margin. The margin for the 2017 Term Loan is fixed at 2.25% for Eurodollar loans, and at 1.25% for ABR loans. For loans under the 2017 Revolving Credit Facility, the margin is determined by reference to our Consolidated Total Debt to Consolidated EBITDA (each as defined in the 2017 Credit Agreement) leverage ratio (the “Leverage Ratio”).

As of July 31, 2017, the interest rate on 2017 Term Loan was 3.47%. Taking into account the impact of the original issuance discount and related deferred debt issuance costs, the effective interest rate on the 2017 Term Loan was approximately 3.65% at July 31, 2017. As of January 31, 2017 the weighted-average interest rate on the 2014 Terms Loans was 3.58%.

We are required to pay a commitment fee with respect to unused availability under the 2017 Revolving Credit Facility at a rate per annum determined by reference to our Leverage Ratio.

The 2017 Term Loan requires quarterly principal payments of approximately $1.1 million commencing on August 1, 2017, with the remaining balance due on June 29, 2024. Optional prepayments of loans under the 2017 Credit Agreement are generally permitted without premium or penalty.

Our obligations under the 2017 Credit Agreement are guaranteed by each of our direct and indirect existing and future material domestic wholly owned restricted subsidiaries, and are secured by a security interest in substantially all of our assets and the assets of the guarantor subsidiaries, subject to certain exceptions.

The 2017 Credit Agreement contains certain customary affirmative and negative covenants for credit facilities of this type. The 2017 Credit Agreement also contains a financial covenant that, solely with respect to the 2017 Revolving Credit Facility, requires us to maintain a Leverage Ratio of no greater than 4.50 to 1. The limitations imposed by the covenants are subject to certain exceptions as detailed in the 2017 Credit Agreement.

The 2017 Credit Agreement provides for events of default with corresponding grace periods that we believe are customary for credit facilities of this type. Upon an event of default, all of our obligations owed under the 2017 Credit Agreement may be declared immediately due and payable, and the lenders’ commitments to make loans under the 2017 Credit Agreement may be terminated.

Loss on Early Retirement of 2014 Term Loans

At the June 29, 2017 closing date of the 2017 Credit Agreement, there were $3.2 million of unamortized deferred debt issuance costs and a $0.1 million unamortized term loan discount associated with the 2014 Term Loans and the Prior Revolving Credit Facility. Of the $3.2 million of unamortized deferred debt issuance costs, $1.4 million was associated with commitments under the Prior Revolving Credit Facility provided by lenders that are continuing to provide commitments under the 2017 Revolving Credit Facility and therefore continued to be deferred, and are being amortized on a straight-line basis over the term of the 2017 Revolving Credit Facility. The remaining $1.8 million of unamortized deferred debt issuance costs and the $0.1 million unamortized discount, all of which related to the 2014 Term Loans, were written off as a $1.9 million loss on early retirement of debt during the three months ended July 31, 2017.

2017 Credit Agreement Issuance Costs

We incurred debt issuance costs of approximately $6.8 million in connection with the 2017 Credit Agreement, which were deferred and are being amortized as interest expense over the terms of the facilities under the 2017 Credit Agreement. Of these deferred debt issuance costs, $4.1 million were associated with the 2017 Term Loan and are being amortized using the effective interest rate method, and $2.7 million were associated with the 2017 Revolving Credit Facility and are being amortized on a straight-line basis.

STOCKHOLDERS’ EQUITY

Dividends on Common Stock

We did not declare or pay any dividends on our common stock during the six months ended July 31, 2017 and 2016. Under the terms of our Credit Agreement, we are subject to certain restrictions on declaring and paying dividends on our common stock.

Share Repurchase Program

On March 29, 2016, we announced that our board of directors had authorized a share repurchase program whereby we may make up to $150.0 million in purchases of our outstanding shares of common stock over the two years following the date of announcement. Under the share repurchase program, purchases can be made from time to time using a variety of methods, which may include open market purchases. The specific timing, price and size of purchases will depend on prevailing stock prices, general market and economic conditions, and other considerations, including the amount of cash generated in the U.S. and other potential uses of cash, such as acquisitions. Purchases may be made through a Rule 10b5-1 plan pursuant to pre-determined metrics set forth in such plan. The authorization of the share repurchase program does not obligate us to acquire any particular amount of common stock, and the program may be suspended or discontinued at any time.

Treasury Stock

Repurchased shares of common stock are recorded as treasury stock, at cost. We periodically purchase treasury stock from directors, officers, and other employees to facilitate income tax withholding and payment requirements upon vesting of equity awards.

During the six months ended July 31, 2017, we received approximately 7,000 shares of treasury stock in a nonmonetary transaction valued at $0.3 million. During the six months ended July 31, 2016, we acquired 500,000 shares of treasury stock at a cost of $17.2 million under the aforementioned share repurchase program.

At July 31, 2017 we held approximately 1,661,000 shares of treasury stock with a cost of $57.4 million. At January 31, 2017, we held approximately 1,654,000 shares of treasury stock with a cost of $57.1 million.

Accumulated Other Comprehensive Income (Loss)

Accumulated other comprehensive income (loss) includes items such as foreign currency translation adjustments and unrealized gains and losses on certain marketable securities and derivative financial instruments designated as hedges. Accumulated other comprehensive income (loss) is presented as a separate line item in the stockholders’ equity section of our condensed consolidated balance sheets. Accumulated other comprehensive income (loss) items have no impact on our net income (loss) as presented in our condensed consolidated statements of operations.

The following table summarizes changes in the components of our accumulated other comprehensive income (loss) by component for the six months ended July 31, 2017:



(in thousands)	Unrealized Gains on Foreign Exchange Contracts Designated as Hedges		Unrealized Gain on Interest Rate Swap Designated as Hedge			Foreign Currency Translation Adjustments			Total
Accumulated other comprehensive income (loss) at January 31, 2017	$	575	$	632		$	(156,063	)	$	(154,856	)
Other comprehensive income (loss) before reclassifications	5,028		(341		)	20,816			25,503

Accumulated other comprehensive income (loss) at July 31, 2017	$	3,016	$	—		$	(135,247	)	$	(132,231	)

All amounts presented in the table above are net of income taxes, if applicable. The accumulated net losses in foreign currency translation adjustments primarily reflect the strengthening of the U.S. dollar against the British pound sterling, which has resulted in lower U.S. dollar-translated balances of British pound sterling-denominated goodwill and intangible assets.

The amounts reclassified out of accumulated other comprehensive income (loss) into the condensed consolidated statement of operations, with presentation location, for the three and six months ended July 31, 2017 and 2016 were as follows:

INCOME TAXES	6 Months Ended
INCOME TAXES	Jul. 31, 2017
Income Tax Disclosure [Abstract]
INCOME TAXES	Our interim (benefit) provision for income taxes is measured using an estimated annual effective income tax rate, adjusted for discrete items that occur within the periods presented. For the three months ended July 31, 2017, we recorded an income tax provision of $4.5 million on a pre-tax loss of $1.3 million, which represented a negative effective income tax rate of 338.8%. The income tax provision does not include income tax benefits on losses incurred by certain domestic and foreign operations where we maintain valuation allowances. Our income in profitable jurisdictions, where we record income tax provisions, was slightly lower than the pre-tax losses in domestic and foreign jurisdictions where we maintain valuation allowances and do not record tax benefits. For the three months ended July 31, 2016, we recorded an income tax provision of $1.1 million on a pre-tax loss of $10.0 million, which represented a negative effective income tax rate of 10.6%. The income tax provision does not include income tax benefits on losses incurred by certain domestic and foreign operations where we maintain valuation allowances and is mainly the result of the activities of profitable jurisdictions. Our pre-tax income in profitable jurisdictions, where we record income tax provisions, was lower than the pre-tax losses in domestic and foreign jurisdictions where we maintain valuation allowances and do not record income tax benefits. For the six months ended July 31, 2017, we recorded an income tax provision of $3.6 million on a pre-tax loss of $21.2 million, which represented a negative effective income tax rate of 16.8%. The income tax provision does not include income tax benefits on losses incurred by certain domestic and foreign operations where we maintain valuation allowances. Our pre-tax income in profitable jurisdictions, where we record income tax provisions, was significantly lower than the pre-tax losses in domestic and foreign jurisdictions where we maintain valuation allowances and do not record income tax benefits. For the six months ended July 31, 2016, we recorded an income tax provision of $1.4 million on a pre-tax loss of $25.9 million, which represented a negative effective income tax rate of 5.4%. The income tax provision does not include income tax benefits on losses incurred by certain domestic and foreign operations where we maintain valuation allowances and is mainly the result of the activities of profitable jurisdictions. Our pre-tax income in profitable jurisdictions, where we record income tax provisions, was significantly lower than the pre-tax losses in domestic and foreign jurisdictions where we maintain valuation allowances and do not record income tax benefits. As required by the authoritative guidance on accounting for income taxes, we evaluate the realizability of deferred income tax assets on a jurisdictional basis at each reporting date. Accounting guidance for income taxes requires that a valuation allowance be established when it is more-likely-than-not that all or a portion of the deferred income tax assets will not be realized. In circumstances where there is sufficient negative evidence indicating that the deferred income tax assets are not more-likely-than-not realizable, we establish a valuation allowance. We determined that there is sufficient negative evidence to maintain the valuation allowances against our federal and certain state and foreign deferred income tax assets as a result of historical losses in the most recent three-year period in the U.S. and in certain foreign jurisdictions. We intend to maintain valuation allowances until sufficient positive evidence exists to support a reversal. We had unrecognized income tax benefits of $152.5 million and $148.6 million (excluding interest and penalties) as of July 31, 2017 and January 31, 2017, respectively. The accrued liability for interest and penalties was $4.3 million and $3.9 million at July 31, 2017 and January 31, 2017, respectively. Interest and penalties are recorded as a component of the provision for income taxes in our condensed consolidated statements of operations. As of July 31, 2017 and January 31, 2017, the total amount of unrecognized income tax benefits that, if recognized, would impact our effective income tax rate were approximately $148.1 million and $143.0 million, respectively. We regularly assess the adequacy of our provisions for income tax contingencies in accordance with the applicable authoritative guidance on accounting for income taxes. As a result, we may adjust the reserves for unrecognized income tax benefits for the impact of new facts and developments, such as changes to interpretations of relevant tax law, assessments from taxing authorities, settlements with taxing authorities, and lapses of statutes of limitation. Further, we believe that it is reasonably possible that the total amount of unrecognized income tax benefits at July 31, 2017 could decrease by approximately $3.1 million in the next twelve months as a result of settlement of certain tax audits or lapses of statutes of limitation. Such decreases may involve the payment of additional income taxes, the adjustment of deferred income taxes including the need for additional valuation allowances, and the recognition of income tax benefits. Our income tax returns are subject to ongoing tax examinations in several jurisdictions in which we operate. We also believe that it is reasonably possible that new issues may be raised by tax authorities or developments in tax audits may occur which would require increases or decreases to the balance of reserves for unrecognized income tax benefits; however, an estimate of such changes cannot reasonably be made.

Our estimated liability for contingent consideration represents potential payments of additional consideration for business combinations, payable if certain defined performance goals are achieved. Changes in fair value of contingent consideration are recorded in the condensed consolidated statements of operations within selling, general and administrative expenses.

During the year ended January 31, 2017, we acquired two majority owned subsidiaries for which we hold an option to acquire the noncontrolling interests. We account for the option as an in-substance investment in the noncontrolling common stock of each such subsidiary. We include the fair value of the option within other liabilities and do not recognize noncontrolling interests in these subsidiaries. The following table presents the change in the estimated fair value of this liability, which is measured using Level 3 inputs, for the six months ended July 31, 2017 and 2016:

There were no transfers between levels of the fair value measurement hierarchy during the six months ended July 31, 2017 and 2016.

Fair Value Measurements

Money Market Funds - We value our money market funds using quoted active market prices for such funds.

Short-term Investments and Commercial Paper - The fair values of short-term investments, as well as commercial paper classified as cash equivalents, are estimated using observable market prices for identical securities that are traded in less-active markets, if available. When observable market prices for identical securities are not available, we value these short-term investments using non-binding market price quotes from brokers which we review for reasonableness using observable market data; quoted market prices for similar instruments; or pricing models, such as a discounted cash flow model.

Foreign Currency Forward Contracts - The estimated fair value of foreign currency forward contracts is based on quotes received from the counterparties thereto. These quotes are reviewed for reasonableness by discounting the future estimated cash flows under the contracts, considering the terms and maturities of the contracts and market foreign currency exchange rates using readily observable market prices for similar contracts.

Interest Rate Swap Agreement - The fair value of our interest rate swap agreement is based in part on data received from the counterparty, and represents the estimated amount we would receive or pay to settle the agreement, taking into consideration current and projected future interest rates as well as the creditworthiness of the parties, all of which can be validated through readily observable data from external sources.

Contingent Consideration - Business Combinations - The fair value of the contingent consideration related to business combinations is estimated using a probability-adjusted discounted cash flow model. These fair value measurements are based on significant inputs not observable in the market. The key internally developed assumptions used in these models are discount rates and the probabilities assigned to the milestones to be achieved. We remeasure the fair value of the contingent consideration at each reporting period, and any changes in fair value resulting from either the passage of time or events occurring after the acquisition date, such as changes in discount rates, or in the expectations of achieving the performance targets, are recorded within selling, general, and administrative expenses. Increases or decreases in discount rates would have inverse impacts on the related fair value measurements, while favorable or unfavorable changes in expectations of achieving performance targets would result in corresponding increases or decreases in the related fair value measurements. We utilized discount rates ranging from 3.0% to 20.0% in our calculations of the estimated fair values of our contingent consideration liabilities as of July 31, 2017 and January 31, 2017.

Option to Acquire Noncontrolling Interests of Consolidated Subsidiaries - The fair value of the option is determined primarily by using the income approach, which discounts expected future cash flows to present value using estimates and assumptions determined by management. This fair value measurement is based upon significant inputs not observable in the market. We remeasure the fair value of the option at each reporting period, and any changes in fair value are recorded within selling, general, and administrative expenses. We utilized discount rates of 12.5% and 14.0% in our calculation of the estimated fair value of the option as of July 31, 2017 and January 31, 2017, respectively.

Other Financial Instruments

The carrying amounts of accounts receivable, accounts payable, and accrued liabilities and other current liabilities approximate fair value due to their short maturities.

The estimated fair values of our term loan borrowings were $427 million and $410 million at July 31, 2017 and January 31, 2017, respectively. The estimated fair values of the term loans are based upon indicative bid and ask prices as determined by the agent responsible for the syndication of our term loans. We consider these inputs to be within Level 3 of the fair value hierarchy because we cannot reasonably observe activity in the limited market in which participations in our term loans are traded. The indicative prices provided to us as at each of July 31, 2017 and January 31, 2017 did not significantly differ from par value. The estimated fair value of our revolving credit borrowings, if any, is based upon indicative market values provided by one of our lenders. We had no revolving credit borrowings at July 31, 2017 and January 31, 2017.

The estimated fair values of our Notes were approximately $388 million and $381 million at July 31, 2017 and January 31, 2017, respectively. The estimated fair values of the Notes are determined based on quoted bid and ask prices in the over-the-counter market in which the Notes trade. We consider these inputs to be within Level 2 of the fair value hierarchy.

Assets and Liabilities Not Measured at Fair Value on a Recurring Basis

In addition to assets and liabilities that are measured at fair value on a recurring basis, we also measure certain assets and liabilities at fair value on a nonrecurring basis. Our non-financial assets, including goodwill, intangible assets and property, plant and equipment, are measured at fair value when there is an indication of impairment and the carrying amount exceeds the asset’s projected undiscounted cash flows. These assets are recorded at fair value only when an impairment charge is recognized.

DERIVATIVE FINANCIAL INSTRUMENTS

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVE FINANCIAL INSTRUMENTS

Our primary objective for holding derivative financial instruments is to manage foreign currency exchange rate risk and interest rate risk, when deemed appropriate. We enter into these contracts in the normal course of business to mitigate risks and not for speculative purposes.

Foreign Currency Forward Contracts

Under our risk management strategy, we periodically use foreign currency forward contracts to manage our short-term exposures to fluctuations in operational cash flows resulting from changes in foreign currency exchange rates. These cash flow exposures result from portions of our forecasted operating expenses, primarily compensation and related expenses, which are transacted in currencies other than the U.S. dollar, most notably the Israeli shekel. We also periodically utilize foreign currency forward contracts to manage exposures resulting from forecasted customer collections to be remitted in currencies other than the applicable functional currency, and exposures from cash, cash equivalents and short-term investments denominated in currencies other than the applicable functional currency. Our joint venture, which has a Singapore dollar functional currency, also periodically utilizes foreign exchange forward contracts to manage its exposure to exchange rate fluctuations related to settlements of liabilities denominated in U.S. dollars. These foreign currency forward contracts generally have maturities of no longer than twelve months, although occasionally we will execute a contract that extends beyond twelve months, depending upon the nature of the underlying risk.

We held outstanding foreign currency forward contracts with notional amounts of $144.8 million and $144.0 million as of July 31, 2017 and January 31, 2017, respectively.

Interest Rate Swap Agreement

To partially mitigate risks associated with the variable interest rates on the term loan borrowings under our Prior Credit Agreement, in February 2016 we executed a pay-fixed, receive-variable interest rate swap agreement with a multinational financial institution under which we pay interest at a fixed rate of 4.143% and receive variable interest of three-month LIBOR (subject to a minimum of 0.75%), plus a spread of 2.75%, on a notional amount of $200.0 million. Although the Prior Credit Agreement was terminated on June 29, 2017, the interest rate swap agreement remains in effect, and serves as an economic hedge to partially mitigate the risk of higher borrowing costs under our 2017 Credit Agreement resulting from increases in market interest rates.

Prior to June 29, 2017, the interest rate swap agreement was designated as a cash flow hedge and as such, changes in its fair value were recognized in accumulated other comprehensive income (loss) in the condensed consolidated balance sheets and were reclassified into the condensed consolidated statements of operations within interest expense in the period in which the hedged transaction affected earnings. Hedge ineffectiveness, if any, was recognized currently in the condensed consolidated statement of operations.

On June 29, 2017, concurrent with the execution of the 2017 Credit Agreement and termination of the Prior Credit Agreement, the interest rate swap agreement was no longer designated as a cash flow hedge for accounting purposes, and because future occurrence of the specific forecasted variable cash flows which had been hedged by the interest rate swap agreement was no longer probable, $0.9 million fair value of the interest rate swap at that date was reclassified from accumulated other comprehensive income (loss) into the condensed consolidated statement of operations as income within other income (expense), net. Ongoing changes in the fair value of the interest rate swap agreement are now recognized within other income (expense), net in the condensed consolidated statement of operations.

Settlements with the counterparty under the interest rate swap agreement occur quarterly, and the agreement will terminate on September 6, 2019.

Fair Values of Derivative Financial Instruments

The fair values of our derivative financial instruments and their classifications in our condensed consolidated balance sheets as of July 31, 2017 and January 31, 2017 were as follows:

Derivative Financial Instruments in Cash Flow Hedging Relationships

The effects of derivative financial instruments designated as cash flow hedges on accumulated other comprehensive loss ("AOCL") and on the condensed consolidated statements of operations for the three and six months ended July 31, 2017 and 2016 were as follows:



	Three Months Ended July 31,						Six Months Ended July 31,

For information regarding the line item locations of the net (losses) gains reclassified out of AOCL into the condensed consolidated condensed statements of operations, see Note 8, "Stockholders' Equity".

There were no gains or losses from ineffectiveness of these cash flow hedges recorded for the three and six months ended July 31, 2017 and 2016. All of the foreign currency forward contracts underlying the $3.0 million of net unrealized gains recorded in our accumulated other comprehensive loss at July 31, 2017 mature within twelve months, and therefore we expect all such gains to be reclassified into earnings within the next twelve months.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

STOCK-BASED COMPENSATION

Amended and Restated Stock-Based Compensation Plan

On June 22, 2017, our stockholders approved the Verint Systems Inc. Amended and Restated 2015 Long-Term Stock Incentive Plan (the "2017 Amended Plan"), which amended and restated the Verint Systems Inc. 2015 Long-Term Stock Incentive Plan (the "2015 Plan"). As with the 2015 Plan, the 2017 Amended Plan authorizes our board of directors to provide equity-based compensation in the form of stock options, stock appreciation rights, restricted stock, restricted stock units, performance awards, other stock-based awards, and performance compensation awards.

The 2017 Amended Plan amends and restates the 2015 Plan to, among other things, increase the number of shares available for issuance under the 2017 Amended Plan. Subject to adjustment as provided in the 2017 Amended Plan, up to an aggregate of (i) 7,975,000 shares of our common stock (on an option-equivalent basis), plus (ii) the number of shares of our common stock available for issuance under the 2015 Plan as of June 22, 2017, plus (iii) the number of shares of our common stock that become available for issuance as a result of awards made under the 2015 Plan or the 2017 Amended Plan that are forfeited, cancelled, exchanged, withheld or surrendered or terminate or expire, may be issued or transferred in connection with awards under the 2017 Amended Plan. Each stock option or stock-settled stock appreciation right granted under the 2017 Amended Plan will reduce the available plan capacity by one share and each other award will reduce the available plan capacity by 2.47 shares.

The 2017 Amended Plan expires on June 22, 2027.

Stock-Based Compensation Expense

We recognized stock-based compensation expense in the following line items on the condensed consolidated statements of operations for the three and six months ended July 31, 2017 and 2016:



	Three Months Ended July 31,				Six Months Ended July 31,
(in thousands)	2017		2016		2017		2016
Cost of revenue - product	$	365	$	399	$	706	$	512
Cost of revenue - service and support	1,713		1,863		2,965		3,254

Total stock-based compensation expense	$	16,804	$	16,388	$	34,487	$	31,728

The following table summarizes stock-based compensation expense by type of award for the three and six months ended July 31, 2017, and 2016:



	Three Months Ended July 31,				Six Months Ended July 31,
(in thousands)	2017		2016		2017		2016
Restricted stock units and restricted stock awards	$	15,307	$	14,523	$	28,749	$	28,489
Stock bonus program and bonus share program	1,428		1,804		5,606		3,149
Total equity-settled awards	16,735		16,327		34,355		31,638
Phantom stock units (cash-settled awards)	69		61		132		90
Total stock-based compensation expense	$	16,804	$	16,388	$	34,487	$	31,728

Awards under our stock bonus and bonus share programs are accounted for as liability-classified awards, because the obligations are based predominantly on fixed monetary amounts that are generally known at inception of the obligation, to be settled with a variable number of shares of our common stock.

Restricted Stock Units

We periodically award restricted stock units ("RSUs") to our directors, officers, and other employees. These awards contain various vesting conditions and are subject to certain restrictions and forfeiture provisions prior to vesting. Some of these RSU awards to executive officers and certain employees vest upon the achievement of specified performance goals or market conditions (performance-based RSUs).

The following table (Award Activity Table) summarizes award activity (including stock-settled RSUs, performance-based stock-settled RSUs, and other awards which reduce available plan capacity) and related information for the six months ended July 31, 2017:



(in thousands, except per share data)	Number of Shares		Weighted-Average Grant Date Fair Value
Awards outstanding, January 31, 2017	2,742		$	45.20
Awards granted	1,744		$	40.13
Awards released	(1,323	)	$	46.08
Awards forfeited	(214	)	$	52.63
Awards outstanding, July 31, 2017	2,949		$	41.29

Our RSU awards may include a provision which allows the awards to be settled with cash payments upon vesting, rather than with delivery of common stock, at the discretion of our board of directors. As of July 31, 2017, for such awards that are outstanding, settlement with cash payments was not considered probable, and therefore these awards have been accounted for as equity-classified awards and are included in the table above.

With respect to our stock bonus program, activity presented in the table above only includes shares earned and released in consideration of the discount provided under that program. Consistent with the provisions of the 2015 Plan and the 2017 Amended Plan, other shares issued under the stock bonus program are not included in the table above because they do not reduce available plan capacity (since such shares are deemed to be purchased by the grantee at fair value in lieu of receiving an earned cash bonus). Activity presented in the table above includes all shares awarded and released under the bonus share program. Further details appear below under "Stock Bonus Program" and "Bonus Share Program".

The following table summarizes activity for performance-based RSUs for the six months ended July 31, 2017 and 2016 in isolation (these amounts are already included in the Award Activity Table above):



	Six Months Ended July 31,
(in thousands)	2017		2016
Beginning balance	438		332
Granted	204		313
Released	(50	)	(159	)
Forfeited	(86	)	(42	)
Ending balance	506		444

As of July 31, 2017, there was approximately $91.8 million of total unrecognized compensation expense, net of estimated forfeitures, related to unvested restricted stock units, which is expected to be recognized over a weighted-average period of 2.0 years. The unrecognized compensation expense does not include compensation expense of up to $1.4 million related to shares for which a grant date has been established but the requisite service period has not begun.

Stock Bonus Program

Our stock bonus program permits eligible employees to receive a portion of their earned bonuses, otherwise payable in cash, in the form of discounted shares of our common stock. Executive officers are eligible to participate in this program to the extent that shares remain available for awards following the enrollment of all other participants. Shares awarded to executive officers with respect to the discount feature of the program are subject to a one-year vesting period. This program is subject to annual funding approval by our board of directors and an annual cap on the number of shares that can be issued. Subject to these limitations, the number of shares to be issued under the program for a given year is determined using a five-day trailing average price of our common stock when the awards are calculated, reduced by a discount determined by the board of directors each year (the "discount"). To the extent that this program is not funded in a given year or the number of shares of common stock needed to fully satisfy employee enrollment exceeds the annual cap, the applicable portion of the employee bonuses will generally revert to being paid in cash. Obligations under this program are accounted for as liabilities, because the obligations are based predominantly on fixed monetary amounts that are generally known at inception of the obligation, to be settled with a variable number of shares of common stock determined using a discounted average price of our common stock.

The following table summarizes activity under the stock bonus program during the six months ended July 31, 2017 and 2016 in isolation. As noted above, shares issued in respect of the discount feature under the program reduce available plan capacity and are included in the Award Activity Table above. Other shares issued under the program do not reduce available plan capacity and are therefore excluded from the Award Activity Table above.

(in thousands)	2017	2016

In March 2017, our board of directors approved up to 125,000 shares of common stock, and a discount of 15%, for awards under our stock bonus programs for the year ending January 31, 2018.

Bonus Share Program

In February 2015, the board of directors authorized a separate program under which we may provide discretionary year-end bonuses to employees in the form of shares of common stock. Unlike the stock bonus program, there is no enrollment for this program and no discount feature. Similar to the accounting for the stock bonus program, obligations for these bonuses are accounted for as liabilities, because the obligations are based predominantly on fixed monetary amounts that are generally known, to be settled with a variable number of shares of common stock.

For bonuses in respect of the year ended January 31, 2017, the board of directors approved the use of up to 300,000 shares of common stock under this program. During the three months ended July 31, 2017, approximately 293,000 shares of common stock were awarded and released under the bonus share program in respect of the year ended January 31, 2017.

The combined accrued liabilities for the stock bonus program and the bonus share program were $2.6 million and $10.0 million at July 31, 2017 and January 31, 2017, respectively. As noted above, shares issued under this program are included in the Award Activity Table above

Legal Proceedings

On March 26, 2009, legal actions were commenced by Ms. Orit Deutsch, a former employee of our subsidiary, Verint Systems Limited ("VSL"), against VSL in the Tel Aviv Regional Labor Court (Case Number 4186/09) (the "Deutsch Labor Action") and against CTI in the Tel Aviv District Court (Case Number 1335/09) (the "Deutsch District Action"). In the Deutsch Labor Action, Ms. Deutsch filed a motion to approve a class action lawsuit on the grounds that she purported to represent a class of our employees and former employees who were granted Verint and CTI stock options and were allegedly damaged as a result of the suspension of option exercises during the period from March 2006 through March 2010, during which we did not make periodic filings with the SEC as a result of certain internal and external investigations and reviews of accounting matters discussed in our prior public filings. In the Deutsch District Action, in addition to a small amount of individual damages, Ms. Deutsch was seeking to certify a class of plaintiffs who were allegedly damaged due to their inability to exercise Verint and CTI stock options as a result of alleged negligence by CTI in its financial reporting. The class certification motions do not specify an amount of damages. On February 8, 2010, the Deutsch Labor Action was dismissed for lack of material jurisdiction and was transferred to the Tel Aviv District Court and consolidated with the Deutsch District Action. On March 16, 2009 and March 26, 2009, respectively, legal actions were commenced by Ms. Roni Katriel, a former employee of CTI's former subsidiary, Comverse Limited, against Comverse Limited in the Tel Aviv Regional Labor Court (Case Number 3444/09) (the "Katriel Labor Action") and against CTI in the Tel Aviv District Court (Case Number 1334/09) (the "Katriel District Action"). In the Katriel Labor Action, Ms. Katriel is seeking to certify a class of plaintiffs who were granted CTI stock options and were allegedly damaged as a result of the suspension of option exercises during an extended filing delay period affecting CTI's periodic reporting discussed in CTI's historical SEC filings. In the Katriel District Action, in addition to a small amount of individual damages, Ms. Katriel is seeking to certify a class of plaintiffs who were allegedly damaged due to their inability to exercise CTI stock options as a result of alleged negligence by CTI in its financial reporting. The class certification motions do not specify an amount of damages. On March 2, 2010, the Katriel Labor Action was transferred to the Tel Aviv District Court, based on an agreed motion filed by the parties requesting such transfer.

On April 4, 2012, Ms. Deutsch and Ms. Katriel filed an uncontested motion to consolidate and amend their claims and on June 7, 2012, the District Court allowed Ms. Deutsch and Ms. Katriel to file the consolidated class certification motion and an amended consolidated complaint against VSL, CTI, and Comverse Limited. Following CTI's announcement of its intention to effect the distribution of all of the issued and outstanding shares of capital stock of its former subsidiary, Comverse, Inc., on July 12, 2012, the plaintiffs filed a motion requesting that the District Court order CTI to set aside up to $150.0 million in assets to secure any future judgment. The District Court ruled at such time that it would not decide this motion until the Deutsch and Katriel class certification motion was heard. Plaintiffs initially filed a motion to appeal this ruling in August 2012, but subsequently withdrew it in July 2014.

Prior to the consummation of the Comverse share distribution, CTI either sold or transferred substantially all of its business operations and assets (other than its equity ownership interests in us and Comverse) to Comverse or unaffiliated third parties. On October 31, 2012, CTI completed the Comverse share distribution, in which it distributed all of the outstanding shares of common stock of Comverse to CTI's shareholders. As a result of the Comverse share distribution, Comverse became an independent public company and ceased to be a wholly owned subsidiary of CTI, and CTI ceased to have any material assets other than its equity interest in us. On September 9, 2015, Comverse changed its name to Xura, Inc. and, on February 28, 2017, Xura, Inc. changed its name to Mavenir Inc.

On February 4, 2013, we merged with CTI. As a result of the merger, we have assumed certain rights and liabilities of CTI, including any liability of CTI arising out of the Deutsch District Action and the Katriel District Action. However, under the terms of the Distribution Agreement between CTI and Comverse relating to the Comverse share distribution, we, as successor to CTI, are entitled to indemnification from Comverse (now Mavenir) for any losses we suffer in our capacity as successor-in-interest to CTI in connection with the Deutsch District Action and the Katriel District Action.

Following an unsuccessful mediation process, the proceeding before the District Court resumed. On August 28, 2016, the District Court (i) denied plaintiffs’ motion to certify the suit as a class action with respect to all claims relating to Verint stock options and (ii) approved the plaintiffs’ motion to certify the suit as a class action with respect to claims of current or former employees of Comverse Limited (now Mavenir) or VSL who held unexercised CTI stock options at the time CTI suspended option exercises. The court also ruled that the merits of the case and any calculation of damages would be evaluated under New York law.

On December 15, 2016, CTI filed with the Supreme Court a motion for leave to appeal the District Court's August 28, 2016 ruling. The plaintiffs did not file an appeal of the District Court's August 28, 2016 ruling. On February 5, 2017, the District Court approved the plaintiff's motion to appoint a new representative plaintiff, Mr. David Vaaknin, for the current or former employees of VSL who held unexercised CTI stock options at the time CTI suspended option exercises in replacement of Ms. Deutsch.

On August 8, 2017, the Supreme Court partially allowed CTI's appeal and ordered the case to be returned to the District Court to determine whether a cause of action exists in this case under New York law, based on CTI's previously submitted expert opinion and the opinion of any expert the plaintiffs elect to introduce. The District Court's decision on this question will act to either affirm its earlier ruling to certify a portion of the suit as a class action or to reverse this class certification. A hearing date before the District Court has not yet been set.

From time to time we or our subsidiaries may be involved in legal proceedings and/or litigation arising in the ordinary course of our business. While the outcome of these matters cannot be predicted with certainty, we do not believe that the outcome of any current claims will have a material effect on our consolidated financial position, results of operations, or cash flows.

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the enterprise’s chief operating decision maker ("CODM"), or decision making group, in deciding how to allocate resources and in assessing performance. Our Chief Executive Officer is our CODM.

Through July 31, 2016, we were organized and had reported our operating results in three operating segments: Enterprise Intelligence, Video Intelligence, and Cyber Intelligence. In August 2016, we reorganized into two businesses and, now report our results in two operating segments, Customer Engagement Solutions ("Customer Engagement") and Cyber Intelligence Solutions ("Cyber Intelligence"). Comparative segment financial information provided for prior periods has been recast to conform to this revised segment structure.

We measure the performance of our operating segments based on segment revenue and segment contribution.

Segment revenue includes adjustments associated with revenue of acquired companies which are not recognizable within GAAP revenue. These adjustments primarily relate to the acquisition-date excess of the historical carrying value over the fair value of acquired companies’ future maintenance and service performance obligations. As the obligations are satisfied, we report our segment revenue using the historical carrying values of these obligations, which we believe better reflects our ongoing maintenance and service revenue streams, whereas GAAP revenue is reported using the obligations’ acquisition-date fair values. Segment revenue adjustments can also result from aligning an acquired company’s historical revenue recognition policies to our policies.

Segment contribution includes segment revenue and expenses incurred directly by the segment, including material costs, service costs, research and development, selling, marketing, and certain administrative expenses. When determining segment contribution, we do not allocate certain operating expenses which are provided by shared resources or are otherwise generally not controlled by segment management. These expenses are reported as “Shared support expenses” in our table of segment operating results, the majority of which are expenses for administrative support functions, such as information technology, human resources, finance, legal, and other general corporate support, and for occupancy expenses. These unallocated expenses also include procurement, manufacturing support, and logistics expenses.

In addition, segment contribution does not include amortization of acquired intangible assets, stock-based compensation, and other expenses that either can vary significantly in amount and frequency, are based upon subjective assumptions, or in certain cases are unplanned for or difficult to forecast, such as restructuring expenses and business combination transaction and integration expenses, all of which are not considered when evaluating segment performance.

Revenue from transactions between our operating segments is not material.

Operating results by segment for the three and six months ended July 31, 2017 and 2016 were as follows:

Operating income (loss)	$	3,946		$	3,749		$	(5,439	)	$	(7,542	)

We identified certain net expenses incurred during the three and six months ended July 31, 2016 which were incorrectly charged against the segment contribution of our Cyber Intelligence segment, which instead should have been included within acquisition, integration, restructuring, and other unallocated expenses. As a result, the Cyber Intelligence segment contribution previously reported for the three months ended July 31, 2016 was overstated by $0.2 million, and for the six months ended July 31, 2016 was understated by $2.4 million, and acquisition, integration, restructuring, and other unallocated expenses were misstated in those periods in the opposite direction by a corresponding amount. The Cyber Intelligence segment contribution and acquisition, integration, restructuring, and other unallocated expenses for the three and six months ended July 31, 2016 as presented the table above reflect the correct classification of these net expenses.

With the exception of goodwill and acquired intangible assets, we do not identify or allocate our assets by operating segment. Consequently, it is not practical to present assets by operating segment. The allocations of goodwill and acquired intangible assets by operating segment appear in Note 5, "Intangible Assets and Goodwill".

BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Jul. 31, 2017
Accounting Policies [Abstract]
Preparation of Condensed Consolidated Financial Statements	Preparation of Condensed Consolidated Financial Statements The condensed consolidated financial statements included herein have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and on the same basis as the audited consolidated financial statements included in our Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission ("SEC") for the year ended January 31, 2017. The condensed consolidated statements of operations, comprehensive (loss) income, stockholders’ equity, and cash flows for the periods ended July 31, 2017 and 2016, and the condensed consolidated balance sheet as of July 31, 2017, are not audited but reflect all adjustments that are of a normal recurring nature and that are considered necessary for a fair presentation of the results for the periods shown. The condensed consolidated balance sheet as of January 31, 2017 is derived from the audited consolidated financial statements presented in our Annual Report on Form 10-K for the year ended January 31, 2017. Certain information and disclosures normally included in annual consolidated financial statements have been omitted pursuant to the rules and regulations of the SEC. Because the condensed consolidated interim financial statements do not include all of the information and disclosures required by GAAP for a complete set of financial statements, they should be read in conjunction with the audited consolidated financial statements and notes included in our Annual Report on Form 10-K filed with the SEC for the year ended January 31, 2017. The results for interim periods are not necessarily indicative of a full year’s results.
Recasting of Prior Period Segment Information	Recasting of Prior Period Segment Information Through July 31, 2016, we were organized and had reported our operating results in three operating segments. In August 2016, we reorganized into two businesses and now report our results in two operating segments, as further discussed in Note 14, "Segment Information". Comparative segment financial information for prior periods appearing in Note 5, "Intangible Assets and Goodwill" and Note 14, "Segment Information", has been recast to conform to this revised segment structure.
Principles of Consolidation	Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of Verint Systems Inc., our wholly owned or otherwise controlled subsidiaries, and a joint venture in which we hold a 50% equity interest. The joint venture is a variable interest entity in which we are the primary beneficiary. Noncontrolling interests in less than wholly owned subsidiaries are reflected within stockholders’ equity on our condensed consolidated balance sheet, but separately from our stockholders' equity. We hold an option to acquire the noncontrolling interests in two majority owned subsidiaries and we account for the option as an in-substance investment in the noncontrolling common stock of each such subsidiary. We include the fair value of the option within other liabilities and do not recognize noncontrolling interests in these subsidiaries. We include the results of operations of acquired companies from the date of acquisition. All significant intercompany transactions and balances are eliminated. Investments in companies in which we have less than a 20% ownership interest and cannot exercise significant influence are accounted for at cost.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires our management to make estimates and assumptions, which may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Accounts Receivable, Net	Accounts Receivable, Net Accounts receivable, net, includes unbilled accounts receivable on arrangements recognized under contract accounting methods, representing revenue recognized on contracts for which billing will occur in subsequent periods, in accordance with the terms of the contracts. Unbilled accounts receivable on such contracts were $62.0 million and $39.7 million at July 31, 2017 and January 31, 2017, respectively. Under most contracts, unbilled accounts receivable are typically billed and collected within one year of revenue recognition. However, as of July 31, 2017, we have unbilled accounts receivable on certain complex projects with a long-standing customer for which the underlying billing milestones are still in progress and have remained unbilled for periods in excess of one year, and in some cases, for several years. Unbilled accounts receivable from this customer have declined significantly over the past year. We have no history of uncollectible accounts with this customer and believe that collection of all unbilled amounts is reasonably assured. We expect billing and collection of all unbilled accounts receivable from this customer to occur within the next twelve months.
Significant Accounting Policies	Significant Accounting Policies Our significant accounting policies are described in Note 1 to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended January 31, 2017. There were no material changes to our significant accounting policies during the six months ended July 31, 2017.
Recent Accounting Pronouncements	Recent Accounting Pronouncements New Accounting Pronouncements Recently Adopted In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-09, Compensation—Stock Compensation (Topic 718), which amends the accounting for stock-based compensation and requires excess tax benefits and deficiencies to be recognized as a component of income tax expense rather than stockholders' equity. This guidance also requires excess tax benefits to be presented as an operating activity on the consolidated statements of cash flows and allows an entity to make an accounting policy election to either estimate expected forfeitures or to account for them as they occur. ASU No. 2016-09 was effective for us on February 1, 2017. The adoption did not result in a cumulative-effect adjustment to retained earnings, and in accordance with the new guidance, we recorded certain tax effects from stock-based compensation awards as components of the benefit for income taxes for the three and six months ended July 31, 2017, whereas such tax effects were previously recognized in stockholders’ equity. These tax effects were not material for the three and six months ended July 31, 2017. Our accounting for forfeitures of stock-based compensation awards has not changed because we have elected to continue our current policy of estimating expected forfeitures. The effects of adopting the other provisions of ASU No. 2016-09 were not material to our condensed consolidated financial statements. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which requires entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The new guidance is effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted as of the beginning of an annual reporting period. The new standard must be adopted using a modified retrospective transition method, with the cumulative effect recognized as of the date of initial adoption. We have elected to early adopt this standard as of February 1, 2017, resulting in a $0.9 million cumulative charge to retained deficit, a $1.3 million reduction to other current assets, and a $0.4 million increase in other assets. New Accounting Pronouncements Not Yet Effective In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities. This update better aligns risk management activities and financial reporting for hedging relationships, simplifies hedge accounting requirements, and improves disclosures of hedging arrangements. ASU No. 2017-12 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. We are currently reviewing this standard to assess the impact on our condensed consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, and ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment. ASU No. 2017-01 clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those periods. While we are still assessing the impact of this standard, we do not believe that the adoption of this guidance will have a material impact on our condensed consolidated financial statements. ASU No. 2017-04 eliminates Step 2 of the goodwill impairment test and requires a goodwill impairment to be measured as the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of its goodwill. The ASU is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. While we are still assessing the impact of this standard, we do not believe that the adoption of this guidance will have a material impact on our condensed consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This update requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This update also requires an entity to disclose the nature of restrictions on its cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. ASU No. 2016-18 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years with early adoption permitted, including adoption in an interim period. We typically have restrictions on certain amounts of cash and cash equivalents, primarily consisting of amounts used to secure bank guarantees in connection with sales contract performance obligations, and expect to continue to have similar restrictions in the future. We currently report changes in such restricted amounts as cash flows from investing activities on our consolidated statement of cash flows. This standard will change that presentation. We are currently reviewing this standard to assess other potential impacts on our condensed consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which provides guidance with the intent of reducing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. ASU No. 2016-15 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years with early adoption permitted, including adoption in an interim period. We are currently reviewing this standard to assess the impact on our condensed consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326). This new standard changes the impairment model for most financial assets and certain other instruments. Entities will be required to use a model that will result in the earlier recognition of allowances for losses for trade and other receivables, held-to-maturity debt securities, loans, and other instruments. For available-for-sale debt securities with unrealized losses, the losses will be recognized as allowances rather than as reductions in the amortized cost of the securities. The new standard is effective for annual periods, and for interim periods within those annual periods, beginning after December 15, 2019, with early adoption permitted. We are currently reviewing this standard to assess the impact on our condensed consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which will require lessees to recognize assets and liabilities for leases with lease terms of more than 12 months. Consistent with current GAAP, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. However, unlike current GAAP, which requires only capital leases to be recognized on the balance sheet, the new guidance will require both types of leases to be recognized on the balance sheet. The new guidance is effective for all periods beginning after December 15, 2018 and we are currently evaluating the effects that the adoption of ASU No. 2016-02 will have on our consolidated financial statements, but anticipate that the new guidance will significantly impact our condensed consolidated financial statements given our significant number of leases. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). ASU No. 2014-09 supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific revenue recognition guidance throughout the Industry Topics of the Accounting Standards Codification. Additionally, this update supersedes some cost guidance included in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. As originally issued, this guidance was effective for interim and annual reporting periods beginning after December 15, 2016, and early adoption was not permitted. In July 2015, the FASB deferred the effective date by one year, to interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, but not before the original effective date of December 15, 2016. The standard allows entities to apply the standard retrospectively to each prior reporting period presented (“full retrospective adoption”) or retrospectively with the cumulative effect of initially applying the standard recognized at the date of initial application (“modified retrospective adoption”). We currently expect to adopt ASU No. 2014-09 using the modified retrospective option. We are continuing to review the impacts of adopting ASU No. 2014-09 to our condensed consolidated financial statements. Based upon our preliminary assessments, we currently do not expect the new standard to materially impact the amount or timing of the majority of revenue recognized in our condensed consolidated financial statements. We are still assessing the impact on the timing of revenue recognized under certain contracts under which customized solutions are delivered over extended periods of time. In addition, the timing of cost of revenue recognition for certain customer contracts requiring significant customization will change, because unlike current guidance, the new guidance precludes the deferral of costs simply to obtain an even profit margin over the contract term. We are also assessing the new standard’s requirement to capitalize costs associated with obtaining customer contracts, including commission payments, which are currently expensed as incurred. Under the new standard, these costs will be deferred on our consolidated balance sheet. We are evaluating the period over which to amortize these capitalized costs. In addition, for sales transactions that have been billed, but for which the recognition of revenue has been deferred and the related account receivable has not been collected, we currently do not recognize deferred revenue or the related accounts receivable on our consolidated balance sheet. Under the new standard, we will record accounts receivable and related contract liabilities for noncancelable contracts with customers when the right to consideration is unconditional, which we currently expect will result in increases in accounts receivable and contract liabilities (currently presented as deferred revenue) on our consolidated balance sheet, compared to our current presentation. Our preliminary assessments of the impacts to our condensed consolidated financial statements of adopting this new standard are subject to change.

- Definition

Disclosure of accounting policy for trade and other accounts receivables. This disclosure may include the basis at which such receivables are carried in the entity's statements of financial position (for example, net realizable value), how the entity determines the level of its allowance for doubtful accounts, when impairments, charge-offs or recoveries are recognized, and the entity's income recognition policies for such receivables, including its treatment of related fees and costs, its treatment of premiums, discounts or unearned income, when accrual of interest is discontinued, how the entity records payments received on nonaccrual receivables and its policy for resuming accrual of interest on such receivables. If the enterprise holds a large number of similar loans, disclosure may include the accounting policy for the anticipation of prepayments and significant assumptions underlying prepayment estimates for amortization of premiums, discounts, and nonrefundable fees and costs.
