ORGANIZATION, BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Company Background

Prior to October 31, 2012, the date of the Share Distribution (as defined below), Comverse, Inc. (the “Company”) was a wholly-owned subsidiary of Comverse Technology, Inc. (“CTI”). The Company was organized as a Delaware corporation in November 1997.

The Company is a leading provider of telecom business enablement solutions for communication service providers (“CSPs”) through a portfolio of product-based solutions and associated services in the following domains:

•

Business Support Systems. The Company provides converged, prepaid and postpaid billing and active customer management systems (“BSS”) for wireless, wireline, cable and multi-play CSPs, delivering a value proposition designed to enable an effective service and data monetization, a consistent, enhanced customer experience, reduced complexity and cost, and real-time choice and control.

•

Policy Solutions. The Company provides CSPs with the ability to better manage their data networks and to better monetize their data network investment through its Policy Management and Policy Enforcement capabilities for wireless and wireline data networks.

•

Digital Services. The Company enables network-based voice and messaging (including voicemail, visual voicemail, call completion, short messaging service ("SMS"), and multimedia picture and video messaging ("MMS")), and digital lifestyle services and Internet Protocol ("IP") based rich communication services (including group chat, file transfer, video share, social, presence and geo-location information).

•

Managed and Professional Services. The Company offers a portfolio of services related to its solutions following the completion of the delivery of the project to the customer (referred to as managed services).

The Share Distribution

On October 31, 2012, CTI completed the spin-off of the Company as an independent, publicly-traded company, accomplished by means of a pro rata distribution of 100% of the Company's outstanding common shares to CTI's shareholders (the “Share Distribution”). Following the Share Distribution, CTI no longer holds any of the Company's outstanding capital stock, and the Company is an independent publicly-traded company.

Immediately prior to the Share Distribution, CTI contributed to the Company Exalink Ltd. (“Exalink”), CTI's wholly-owned subsidiary. Other than holding certain intellectual property rights, Exalink has no operations. Following the Share Distribution, the Company and CTI operated independently, and neither had any ownership interest in the other. In order to govern certain ongoing relationships between CTI and the Company after the Share Distribution and to provide mechanisms for an orderly transition, CTI and the Company entered into agreements pursuant to which certain services and rights are provided for following the Share Distribution, and CTI and the Company agreed to indemnify each other against certain liabilities that may arise from their respective businesses and the services that are provided under such agreements. Following the completion of CTI's merger with Verint Systems Inc. (“Verint”) discussed below, these obligations continue to apply between the Company and Verint (see Note 3, Expense Allocations and Share Distribution Agreements).

Upon completion of the Share Distribution, the Company's shares were listed, and began trading, on NASDAQ under the symbol “CNSI.” In connection with the Share Distribution, the Company (1) recapitalized its Net Investment of CTI with its common stock, whereby each holder of CTI common shares outstanding as of the record date for the Share Distribution received one share of the Company's common stock for every ten CTI common shares held thereby, which resulted in the issuance of approximately 21.9 million shares of the Company's common stock, (2) received contributions from CTI of $38.5 million in cash and $1.4 million of property and equipment based on CTI's book value, (3) recorded transfers of lease deposits of $0.8 million and deferred lease cost of $1.0 million from CTI, (4) assumed $0.7 million of employee related liabilities transferred to the Company from CTI, and (5) settled borrowings under a revolving loan agreement of $9.0 million and note payable by the Company to CTI of $9.4 million through a capital contribution to the Company's equity by CTI (see Note 11, Debt). In addition, on November 1, 2012 in connection with the Share Distribution, CTI's equity-based compensation awards held by the Company's employees were replaced with the Company's equity-based compensation awards (see Note 15, Stock-Based Compensation).

Merger of CTI and Verint

On August 12, 2012, CTI entered into an agreement and plan of merger (the “Verint Merger Agreement”) with Verint, its then majority-owned publicly-traded subsidiary, providing for the merger of CTI with and into a subsidiary of Verint to become a wholly-owned subsidiary of Verint (the “Verint Merger”). The Verint Merger was completed on February 4, 2013. The Company agreed to indemnify CTI and its affiliates (including Verint after the Verint Merger) against certain losses that may arise as a result of the Verint Merger and the Share Distribution (see Note 3, Expense Allocations and Share Distribution Agreements). On February 4, 2013, in connection with the closing of the Verint Merger Agreement, CTI placed $25.0 million in escrow to support indemnification claims to the extent made against the Company by Verint and any cash balance remaining in such escrow fund 18 months after the closing of the Verint Merger (the "Escrow Release Date"), less any claims made on or prior to such date, will be released to the Company. Although no indemnification claims have been filed and the Escrow Release Date is within 12 months of January 31, 2014, the Company continues to classify the restricted cash balance as "Long-term restricted cash" in the Consolidated Balance Sheets until it can be determined if any future claims would restrict the release of such escrow funds. As of the closing of the Verint Merger, the Company recognized the estimated fair value of the potential indemnification liability of $4.0 million with the remaining $21.0 million as an additional contribution from CTI. As of January 31, 2014, the estimated fair value of the potential indemnification liability is $3.8 million.

Contribution and Sale of Starhome

Starhome was a CTI subsidiary (66.5% owned as of January 31, 2012). On August 1, 2012, CTI, certain other Starhome shareholders and Starhome entered into a Share Purchase Agreement (the “Starhome Share Purchase Agreement”) with Fortissimo Capital Fund II (Israel), L.P., Fortissimo Capital Fund III (Israel), L.P. and Fortissimo Capital Fund III (Cayman), L.P. (collectively, “Fortissimo”) pursuant to which Fortissimo agreed to purchase all of the outstanding share capital of Starhome (the “Starhome Disposition”). On September 19, 2012, CTI, in order to ensure it could meet the conditions of the Verint Merger, contributed to the Company its interest in Starhome, including its rights and obligations under the Starhome Share Purchase Agreement. The Starhome Disposition was completed on October 19, 2012.

As a result of the Starhome Disposition, the results of operations of Starhome, including the gain on sale of Starhome, net of tax, are included in discontinued operations, less applicable income taxes, as a separate component of net income (loss) in the Company’s consolidated and combined statements of operations for the fiscal years ended January 31, 2013 and 2012 (see Note 16, Discontinued Operations).

Basis of Presentation

The consolidated and combined financial statements included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

The Company’s combined financial statements for the periods prior to the Share Distribution have been derived from the consolidated financial statements and accounting records of CTI, using the historical results of operations, and historical basis of assets and liabilities of the Company’s businesses, which operated under common control of CTI. The Company’s combined financial statements combine, on the basis of common control, the results of operations and financial position of the Company and its subsidiaries with Starhome (66.5% owned by CTI as of January 31, 2012) and Exalink prior to CTI contributing Starhome and Exalink to the Company on September 19, 2012 and October 31, 2012, respectively. Management believes the assumptions and methodologies underlying the allocation of general, corporate expenses from CTI are reasonable (see Note 3, Expense Allocations and Share Distribution Agreements). However, such expenses may not be indicative of the actual level of expense that would have been incurred by the Company if it had operated as an independent, publicly-traded company. As such, the combined financial statements for periods prior to the Share Distribution included herein may not necessarily reflect what its results of operations, financial position, comprehensive income (loss) or cash flows would have been had the Company been an independent company during the periods presented. Subsequent to the Share Distribution, the financial statements are consolidated.

Prior to the Share Distribution, transactions between the Company and CTI and CTI’s other subsidiaries were identified in the consolidated and combined financial statements as transactions between related parties (see Note 22, Related Party Transactions).

For the purposes of the consolidated and combined statements of cash flows, prior to the Share Distribution, the Company reflected changes in unpaid balances with CTI as a financing activity.

Intercompany accounts and transactions within the Company have been eliminated.

Segment Reporting

The Company determines its reportable segments in accordance with the Financial Accounting Standards Board's (the “FASB”) guidance relating to disclosures about segments of an enterprise and related information. The Company's Chief Executive Officer is its chief operating decision maker (the “CODM”). The CODM uses segment performance as its primary basis for assessing the financial results of the operating segments and for the allocation of resources (see Note 20, Business Segment Information, for additional discussion, including the definition of segment performance).

The Company's operating and reportable segments are as follows:

•

BSS, which conducts the Company's converged, prepaid and postpaid billing and active customer management systems business along with its policy solutions products and includes groups engaged in product management, delivery, support, professional services, research and development and product sales support; and

•

Digital Services, which conducts the Company's digital services business and includes groups engaged in product management, delivery, support, professional services, research and development and product sales support.

The Company does not maintain separate balance sheets for the BSS and Digital Services segments.

The results of operations of the Company's global corporate functions, that provide common support to its segments, are included in the column captioned “All Other” as part of the Company's business segment presentation. All Other includes sales, marketing, finance, legal, and management as they provide services to both the BSS and Digital Services segments. In addition, there are certain delivery, support, and research and development groups that provide common support to the BSS and Digital Services segments, and therefore the costs of these common groups are included in All Other.

Starhome's results of operations are included in discontinued operations and therefore not presented in segment information.

Historically, Mobile Internet (“Comverse MI”), which was renamed Policy and is responsible for the Company's mobile Internet and policy products, and Netcentrex, an IP-based solution that provides carrier-hosted enterprise and consumer IP services, were included in All Other. Effective in the three months ended January 31, 2014 ("fourth quarter of fiscal 2013"), Comverse MI and Netcentrex have been combined with the Comverse BSS and Comverse Value Added Services (“VAS”) segments, respectively, to form the “BSS” and “Digital Services” segments. The change in segment reporting aligns with information reviewed by the Company's CODM, a change in management structure and the convergence of operations to take advantage of potential synergies. Accordingly, the results presented under segment reporting reflect the change in segment reporting for all periods presented to conform to the current period segment reporting structure. The change in segment reporting does not affect the Company’s previously reported consolidated and combined financial statements.

Use of Estimates

The preparation of the consolidated and combined financial statements and the accompanying notes in conformity with U.S. GAAP requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses.

The most significant estimates among others include:

•

Estimates relating to the recognition of revenue, including the determination of vendor specific objective evidence (“VSOE”) of fair value and the determination of best estimate of selling price for multiple element arrangements;

•

Fair value of stock-based compensation;

•

Fair value of reporting units for the purpose of goodwill impairment testing;

•

Realization of deferred tax assets;

•

The identification and measurement of uncertain tax positions;

•

Contingencies and litigation;

•

Total estimates to complete on percentage-of-completion (“POC”) projects;

•

Valuation of inventory;

•

Israel employees severance pay;

•

Probability assessment of performance based stock units vesting;

•

Allowance for doubtful accounts;

•

Valuation of other intangible assets; and

•

Allocation of expenses by CTI to the Company.

The Company’s actual results may differ from its estimates.

Functional Currency and Foreign Currency Translation and Transactions

The determination of the functional currency for the Company's foreign subsidiaries is made based on appropriate economic factors, including the currency in which the subsidiary sells its products, the sales market in which the subsidiary operates and the currency in which the subsidiary's financing is denominated. For foreign subsidiaries whose functional currency is not the U.S. dollar, assets and liabilities are translated using current exchange rates at the balance sheet date, and income and expense accounts using average exchange rates for the period, except revenue previously deferred which is translated using historical rates. The resulting foreign currency translation adjustments are reported as a separate component of “Other comprehensive income (loss), net of tax” in the consolidated and combined statements of comprehensive income (loss). For foreign subsidiaries whose functional currency is not the local currency, remeasurement gains and losses are recorded during each period in “Other expense, net” in the consolidated and combined statements of operations.

Unrealized and realized foreign currency transaction gains and losses on transactions denominated in currencies other than the functional currency of the entity are included in the consolidated and combined statements of operations in “Other expense, net” for the period in which the exchange rates changed.

Cash and Cash Equivalents

Cash primarily consists of cash on hand and bank deposits. Cash equivalents primarily consist of interest-bearing money market accounts, commercial paper, agency notes and other highly liquid investments with an original maturity of three months or less when purchased. The Company maintains cash and cash equivalents in U.S. dollars and in foreign currencies, which are subject to risks related to foreign currency exchange rate fluctuations.

Restricted Cash and Bank Time Deposits

Restricted cash and bank time deposits include compensating cash balances related to existing lines of credit and deposits that are pledged as collateral or restricted for use to settle specified performance guarantees to customers and vendors, letters of credit, indemnification claims, foreign currency transactions in the ordinary course of business and pending tax judgments. Cash expected to be restricted for more than one year from the balance sheet date is classified as long-term restricted cash. Restricted bank time deposits generally consist of certificates of deposit with original maturities of twelve months or less.

Accounts Receivable, Net

The application of revenue recognition guidance often results in circumstances for which the Company is unable to recognize revenue relating to sales transactions that have been billed. In these circumstances, the Company does not recognize the deferred revenue or the related accounts receivable and no amounts are recognized in the consolidated balance sheets for such transactions with the exception of certain arrangements recognized in accordance with the FASB's guidance relating to accounting for performance of construction-type and certain production-type contracts. Only to the extent that the Company has recognized revenue and not received cash for such transactions are amounts included in “Accounts receivable, net.” Also, only to the extent that the Company has received cash for such transactions is the amount included in “Deferred revenue” in the consolidated balance sheets.

Accounts receivable, net includes $13.9 million and $15.5 million of a long-term contract as of January 31, 2014 and 2013, respectively, which has associated corresponding deferred revenue classified in current liabilities of $46.5 million and $44.6 million as of January 31, 2014 and 2013, respectively.

Allowance for Doubtful Accounts

The Company estimates the collectability of its accounts receivable balances for each accounting period and adjusts its allowance for doubtful accounts accordingly. The Company exercises judgment in assessing the collectability of accounts receivable, including consideration of current economic conditions, the creditworthiness of customers, their collection history and the related aging of past due receivables balances. The Company evaluates specific accounts when it becomes aware that a customer may be experiencing a deterioration of its financial condition due to lower credit ratings, bankruptcy or other factors that may affect such customer's ability to meet its payment obligations. The Company expenses uncollectible trade receivables when all collection efforts have been exhausted and the Company believes the amount will not be collected.

Investments

The Company accounts for investments in accordance with the FASB's guidance relating to accounting for certain investments in debt and equity securities. Purchases are recorded on the settlement date.

Interest on short-term investments is recognized in the consolidated and combined statements of operations when earned. Realized gains and losses on available-for-sale securities are recognized when securities are sold and are calculated using the specific identification method, and are recorded in “Other expense, net” in the consolidated and combined statements of operations. Unrealized gains and losses, net of taxes, are recorded as a component of “Accumulated other comprehensive income” in the consolidated and combined statements of equity.

Generally, investments with original maturities of greater than three months and remaining maturities of less than one year are classified as short-term investments.

The Company reviews its investments for indications of impairment in value on a quarterly basis. The Company considers an investment to be impaired when the fair value is less than the carrying value (or amortized cost). The Company evaluates each impaired investment individually to determine whether such investment is other-than-temporarily impaired.

Inventories

Inventories are stated at the lower of cost or market. Cost is determined by the first-in, first-out or weighted-average methods which approximates the first-in, first-out method. The Company reduces the carrying value of inventory when it holds excess or obsolete inventories determined through an evaluation of both historical usage and expected future demand. Part of the raw materials comprises software licenses, which are capitalized into inventory upon purchase from a vendor when the license will be used by the Company as part of its deliverables to its customers. Such expenses are included as a component of “Product costs” in the consolidated and combined statements of operations.

The Company evaluates slow moving or obsolete inventory for impairment. Raw material hardware is evaluated based upon utilization and projected usage. Raw material software is written-off upon determination that licenses will no longer be used in products nor can be converted to use within the organization or with other licenses/products.

Property and Equipment

Property and equipment are carried at cost less accumulated depreciation and amortization. The Company depreciates and amortizes its property and equipment on a straight-line basis. Leasehold improvements are capitalized and amortized over the shorter of their estimated useful lives or the related lease term. The cost of maintenance and repairs is expensed as incurred. The estimated useful lives of property and equipment are as follows:

Business Combinations

The Company allocates the fair value of consideration transferred in a business combination to the estimated fair value at the acquisition date of the tangible and intangible assets acquired, the liabilities assumed and any non-controlling interest. Acquisition costs are expensed as incurred. Any residual consideration is recorded as goodwill. The fair value of consideration includes cash, equity securities, other assets and contingent consideration. The Company remeasures the fair value of contingent consideration at each reporting period and any change in the fair value from either the passage of time or events occurring after the acquisition date, is recorded in earnings. The Company's determination of the fair values of assets acquired and liabilities assumed requires the Company to make significant estimates, primarily with respect to intangible assets. These estimates can include, but are not limited to, cash flow projections for the acquired business, and the appropriate weighted-average cost of capital. The results of operations of the acquired business are included in the Company's consolidated and combined results of operations from the date of the acquisition. The Company had no business combinations in any period presented.

Noncontrolling Interest

Noncontrolling interest represents the minority shareholders' interest in Starhome, the Company's former majority-owned subsidiary (see Note 16, Discontinued Operations). The Company recognizes income attributable to the noncontrolling interest as a separate component of net income (loss) in the Company's consolidated and combined statements of operations.

Prior to the Starhome Disposition, the noncontrolling interest of Starhome was 33.5%.

Goodwill

Goodwill represents the excess of the fair value of consideration transferred in a business combination over the fair value of tangible and intangible assets acquired net of the fair value of liabilities assumed and the fair value of any noncontrolling interest in the acquiree. The Company has no indefinite-lived intangible assets other than goodwill. The carrying amount of goodwill is reviewed annually for impairment on November 1 and whenever events or changes in circumstances indicate that the carrying value may not be recoverable.

The Company applies the FASB's guidance when testing goodwill for impairment which permits the Company to make a qualitative assessment of whether goodwill is impaired, or opt to bypass the qualitative assessment, and proceed directly to performing the first step of the two-step impairment test. If the Company performs a qualitative assessment and concludes it is more-likely-than-not that the fair value of a reporting unit exceeds its carrying value, goodwill is not considered impaired and the two-step impairment test is unnecessary. However, if the Company concludes otherwise, it is then required to perform the first step of the two-step impairment test.

The Company has the unconditional option to bypass the qualitative assessment for any reporting unit and proceed directly to performing the first step of the goodwill impairment test. The Company may resume performing the qualitative assessment in any subsequent period.

For reporting units where the Company decides to perform a qualitative assessment, the Company's management assesses and makes judgments regarding a variety of factors which potentially impact the fair value of a reporting unit, including general economic conditions, industry and market-specific conditions, customer behavior, cost factors, financial performance and trends, strategies and business plans, capital requirements, management and personnel issues, and stock price, among others. Management then considers the totality of these and other factors, placing more weight on the events and circumstances that are judged to most affect a reporting unit's fair value or the carrying amount of its net assets, to reach a qualitative conclusion regarding whether it is more-likely-than-not that the fair value of a reporting unit exceeds its carrying amount.

For reporting units where the Company performs the two-step goodwill impairment test, the first step requires the Company to compare the fair value of each reporting unit to the carrying value of its net assets. The Company considers both an income-based approach using projected discounted cash flows and a market-based approach using multiples of comparable companies to determine the fair value of its reporting units. The Company's estimate of fair value of each reporting unit is based on a number of subjective factors, including: (i) the appropriate weighting of valuation approaches (income-based approach and market-based approach), (ii) estimates of the future revenue and cash flows, (iii) discount rate for estimated cash flows, (iv) selection of peer group companies for the market-based approach, (v) required levels of working capital, (vi) assumed terminal value, (vii) the time horizon of cash flow forecasts; and (viii) control premium.

If the fair value of the reporting unit exceeds its carrying value, goodwill is not considered impaired and no further evaluation is necessary. If the carrying value of the reporting unit is greater than the estimated fair value of the reporting unit, there is an indication that impairment may exist and the second step is required. In the second step, the implied fair value of goodwill is calculated as the excess of the fair value of a reporting unit over the fair value assigned to its assets and liabilities. If the implied fair value of goodwill is less than the carrying value of the reporting unit's goodwill, the difference is recognized as an impairment charge.

The Company recorded an impairment charge of approximately $5.6 million for the fiscal year ended January 31, 2013. The Company did not record any impairment of goodwill for the fiscal years ended January 31, 2014 and 2012.

The Company's forecasts and estimates are based on assumptions that are consistent with the plans and estimates used to manage the business. Changes in these estimates could change the conclusion regarding an impairment of goodwill.

Impairment of Long-Lived and Intangible Assets

The Company reviews the recoverability of its long-lived assets, such as property and equipment and intangible assets with finite lives, whenever events or changes in circumstances occur that indicate that the carrying value of the asset may not be recoverable. Any impairment of these assets must be considered prior to the Company's impairment review of goodwill. The assessment of impairment is based on the Company's ability to recover the carrying value of the asset by analyzing the expected future undiscounted pre-tax cash flows specific to the asset or asset group.

Circumstances which could trigger a review include, but are not limited to, significant decreases in the market price of the asset, significant adverse changes in the business climate or legal factors, accumulation of costs significantly in excess of the amount expected for the acquisition of a long-lived asset, current period negative cash flow or operating losses combined with a history of losses or a forecast of continuing losses associated with the use of the asset.

The Company assesses the recoverability of the carrying value of long-lived assets at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. If undiscounted cash flows are less than the carrying value of such asset or asset group, an impairment loss is measured based on the difference between estimated fair value and carrying value. An impairment loss on intangible assets is reported as “Impairment of intangible assets” in the consolidated and combined statements of operations. Assets to be disposed of are written-down to the greater of fair value or salvage value. Estimated fair values are based on assumptions regarding the amount and timing of estimated future cash flows and appropriate discount rates to reflect varying degrees of perceived risk.

The Company did not record any impairment of intangible assets for the fiscal years ended January 31, 2014, 2013 and 2012.

Fair Value Measurements

Under the FASB's guidance, fair value is defined as the price that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., “the exit price”).

In determining fair value, the Company uses various valuation approaches, including quoted market prices and discounted cash flows. The FASB's guidance also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from independent sources. Unobservable inputs are inputs that reflect a company's judgment concerning the assumptions that market participants would use in pricing the asset or liability developed based on the best information available under the circumstances. The fair value hierarchy is broken down into three levels based on the reliability of inputs as follows:

Level 1-Valuations based on quoted prices in active markets for identical instruments that the Company is able to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these instruments does not entail a significant degree of judgment.

Level 2-Valuations based on quoted prices in active markets for instruments that are similar, or quoted prices in markets that are not active for identical or similar instruments, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.

Level 3-Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an asset or liability is classified in its entirety based on the lowest level of input that is significant to the measurement of fair value.

Fair value is a market-based measure considered from the perspective of a market participant who holds the asset or owes the liability rather than an entity-specific measure. Therefore, even when market assumptions are not readily available, the Company's own assumptions are set to reflect those that market participants would use in pricing the asset or liability at the measurement date. The Company uses prices and inputs that are current as of the measurement date, including during periods of market dislocation.

The FASB's guidance requires that the valuation techniques used are consistent with at least one of the three possible approaches: the market approach, income approach, and/or cost approach. The Company's Level 2 valuations use the market approach and are based on significant other observable inputs such as quoted prices for financial instruments not traded on a daily basis.

The FASB's guidance relating to the fair value option for financial assets and financial liabilities permits an instrument-by-instrument irrevocable election to account for selected financial instruments at fair value. The Company elected not to apply the fair value option to any eligible financial assets or financial liabilities.

The Company also elected not to apply the fair value option for non-financial assets and non-financial liabilities.

Derivative Instruments and Hedge Accounting

As part of the Company's risk management strategy, it uses derivative financial instruments, primarily forward contracts, to hedge against certain foreign currency exposures. The Company recognizes all derivatives as either assets or liabilities in the consolidated balance sheets at their fair value on a trade date basis. Short-term derivatives in a gain position are reported in “Prepaid expenses and other current assets” in the consolidated balance sheets and derivatives in a loss position are recorded in “Other current liabilities” in the consolidated balance sheets.

In order to qualify for hedge accounting, the Company formally documents at the inception of each hedging relationship the hedging instrument, the hedged item, the risk management objective and strategy for undertaking each hedging relationship, and the method used to assess hedge effectiveness, which includes the Company's assessment of the creditworthiness of each party and their ability to comply with the contractual terms of the hedging derivative.

When derivative financial instruments qualify for cash flow hedge accounting, the Company records the effective portion of changes in fair value as part of other comprehensive income (loss) in the consolidated and combined statements of equity. When the hedged item is recognized in the consolidated and combined statements of operations, the related derivative gain or loss is reclassified from “Accumulated other comprehensive income (loss)” in the consolidated and combined statements of equity to the consolidated and combined statements of operations within the line item in which the hedged item is recorded. The cash flows from a derivative financial instrument qualifying for cash flow hedge accounting are classified in the consolidated and combined statements of cash flows in the same category as the cash flows from the hedged item.

If a derivative financial instrument does not qualify for hedge accounting, the Company records the changes in fair value of derivative instruments in “Other expense, net” in the consolidated and combined statements of operations.

The Company does not purchase, hold or sell derivative financial instruments for trading and speculative purposes.

Concentration of Credit Risk

Financial instruments, which potentially expose the Company to credit risk, consist primarily of investments, derivatives and accounts receivable. From time to time, the Company invests excess cash in high credit-quality financial institutions and invests primarily in money market funds placed with major banks and financial institutions and corporate commercial paper. The Company believes that the financial institutions that hold its cash and liquid investments are financially sound and accordingly minimal credit risk exists with respect to these balances.

A significant portion of accounts receivable are with communication service providers. However, the concentration of credit risk is diversified due to the large number of commercial and government entities comprising the Company's customer base and their dispersion across different industries and geographic regions. The Company manages credit risk on trade accounts receivable by performing ongoing credit evaluations of its customers' financial condition and limiting the extension of credit when deemed necessary.

For the fiscal years ended January 31, 2014 and 2013, one customer represented approximately 18% and 14%, respectively, of total revenue, in which revenue is attributable to the Digital Services segment. No customer accounted for 10% or more of total revenue for the fiscal year ended January 31, 2012.

For the fiscal years ended January 31, 2014 and 2013, one customer accounted 16% and 13% of the combined accounts receivable as of January 31, 2014 and 2013, respectively. The revenues related to these receivables have been completely deferred in each of the periods presented. Additionally, another customer accounted for 13% of the combined accounts receivable as of January 31, 2013. The Company believes that no significant customer credit risk exists other than what is reserved.

The Company depends on a limited number of suppliers and manufacturers for certain components and is exposed to the risk that these suppliers and manufacturers will not be able to fill its orders on a timely basis and at the specifications it requires.

Revenue Recognition

The Company reports its revenue in two categories: (i) product revenue, including hardware and software products; and (ii) service revenue, including revenue from professional services, training services and post-contract customer support (“PCS”). Professional services primarily include installation, customization and consulting services.

The Company's revenue is accounted for in accordance with the FASB's guidance relating to multiple element arrangements entered into or materially modified on or after February 1, 2011 that include hardware which functions together with software to provide the essential functionality of the product. Revenue recognition for software and (or) services arrangements are accounted under the FASB's new guidance applicable to multiple element arrangements. In applying the FASB's guidance, the Company exercises judgment and uses estimates in determining the revenue to be recognized in each accounting period.

For arrangements that do not require significant customization of the underlying software, the Company recognizes revenue when it has persuasive evidence of an arrangement, the product has been shipped and the services have been provided to the customer, the sales price is fixed or determinable, collectability is probable, and all other pertinent criteria are met as required by the FASB's guidance.

In certain instances, payment terms extend beyond the Company's customary practices. In these situations, if a customer does not have an adequate history of abiding by its contractual payment terms without concessions, the sales price is not considered fixed or determinable. As such, revenue recognition commences upon collection, provided all other revenue recognition criteria have been met.

Under certain contractual arrangements, the Company is required to pay a penalty or liquidated damages if delivery of the Company's products and installation services are not completed by a certain date. In other arrangements, the Company has guaranteed product performance and warranty service response rates, which, if not met, can result in penalties. The Company assesses whether such penalties are akin to a warranty provision or contingent revenue. To the extent that the penalties are akin to a warranty provision, the Company accounts for such penalties or liquidated damages in accordance with the FASB's guidance relating to contingencies.

Shipping and handling amounts billed to the Company's customers are included in product revenue and the related shipping and handling costs are included in product costs.

The Company reports revenue net of any revenue-based taxes assessed by governmental authorities that are imposed on and concurrent with specific revenue producing transactions.

The following are the specific revenue recognition policies for each major category of revenue.

Multiple Element Arrangements

Revenue arrangements may incorporate one or more elements in a single transaction or combination of related transactions. In September 2009, the FASB issued revenue recognition guidance applicable to multiple element arrangements, which applies to multiple element revenue arrangements that contain both software and hardware elements, focusing on determining which revenue arrangements are within the scope of the software revenue guidance; and addresses how to separate consideration related to each element in a multiple element arrangement, excluding software arrangements, and establishes a hierarchy for determining the selling price of an element. It also eliminates the residual method of allocation by requiring that arrangement consideration be allocated at the inception of the arrangement to all elements using the relative selling price method.

Certain of the Company's multiple element arrangements include hardware that functions together with software to provide the essential functionality of the product. Therefore, such arrangements entered into or materially modified on or after February 1, 2011 are no longer accounted for in accordance with the FASB's software accounting guidance. Accordingly, the selling price used for each deliverable is based on VSOE of fair value, if available, third party evidence (“TPE”) of fair value if VSOE is not available, or the Company's best estimate of selling price (“BESP”) if neither VSOE nor TPE is available. In determining the units of accounting for these arrangements, the Company evaluates whether each deliverable has stand-alone value as defined in the FASB's guidance. Given that the hardware and software function together to provide the essential functionality of the product and each element is critical to the overall tangible product sold, neither the software nor the hardware have stand-alone value. Professional services performed prior to the product's acceptance do not have stand-alone value and are therefore combined with the related hardware and software as one non-software deliverable. After determining the fair value for each deliverable, the arrangement consideration is allocated using the relative selling price method. Revenue is recognized accordingly for each deliverable once the respective revenue recognition criteria are met for that deliverable.

The Company has not yet established VSOE of fair value for any element other than PCS for a portion of its arrangements. Generally, the Company is not able to determine TPE because its offerings contain a significant level of differentiation such that the comparable pricing of substantially similar products or services cannot be obtained. When the Company is unable to establish fair value of its non-software deliverables using VSOE or TPE, it uses BESP in its allocation of arrangement consideration. The objective of BESP is to determine the price at which it would transact a sale if the product or service were sold on a stand-alone basis, which requires significant judgment. The Company determines BESP for a product or service by considering multiple factors, including, but not limited to, cost of products, gross margin objectives, pricing practices, geographies and customer classes. The Company exercises judgment and uses estimates in determining the revenue to be recognized in each accounting period.

The majority of multiple element arrangements contain at least two of the following elements: (1) tangible product (hardware, software, and professional services performed prior to the product's acceptance), (2) PCS, (3) training, and (4) post acceptance services. The Company's tangible products are rarely sold separately. In addition, the Company's tangible products are complex, and contain a high degree of customizations such that the Company is unable to demonstrate pricing within a pricing range to establish BESP as very few contracts are comparable. Therefore, the Company has concluded that cost plus a target gross profit margin provides the best estimate of the selling price.

PCS, training, and post acceptance services have various pricing practices based on several factors, including the geographical region of the customer, the size of the customer's installed base, the volume of services being sold and the type or class of service being performed. As noted above, the Company has VSOE of PCS for a portion of its arrangements. For PCS, the Company uses its minimum substantive VSOE thresholds by region plus a reasonable margin as the basis to estimate BESP of PCS for transactions that do not meet the VSOE criteria. For training and post-acceptance services, the Company performs an annual study of stand-alone training and post-acceptance sales to arrive at BESP. While the study does not result in VSOE, it is useful in determining the Company's BESP.

With the exception of arrangements that require significant customization of the product to meet the particular requirements of the customer, which are accounted for using the percentage-of-completion method, the initial revenue recognition for each non-software product only deliverable is generally upon completion of the related professional services.

For all multiple element arrangements without hardware, the Company allocates revenue to the delivered elements of the arrangement using the residual method, whereby revenue is allocated to the undelivered elements based on VSOE of fair value of the undelivered elements with the remaining arrangement fee allocated to the delivered elements and recognized as revenue assuming all other revenue recognition criteria are met. If the Company is unable to establish VSOE of fair value for the undelivered elements of the arrangement, revenue recognition is deferred for the entire arrangement until all elements of the arrangement are delivered. However, if the only undelivered element is PCS, the Company recognizes the arrangement fee ratably over the PCS period.

PCS revenue is derived primarily from providing technical software support services, unspecified software updates and upgrades to customers on a when and if available basis. PCS revenue is recognized ratably over the term of the PCS period. When PCS is included within a multiple element arrangement and the arrangement is within the scope of the software revenue guidance, the Company primarily utilizes the substantive renewal rate to establish VSOE of fair value for PCS.

The Company's policy for establishing VSOE of fair value for professional services and training is based upon an analysis of separate sales of services, which are then compared with the fees charged when the same elements are included in a multiple element arrangement. The Company has not yet established VSOE of fair value for any element other than PCS.

When using the substantive renewal rate method, the Company may be unable to establish VSOE of fair value for PCS because the renewal rate is deemed to be non-substantive or there are no contractually-stated renewal rates. If the stated renewal rate is non-substantive, the entire arrangement fee is recognized ratably over the estimated economic life of the product (five to eight years) beginning upon delivery of all elements other than PCS. The Company believes that the estimated economic life of the product is the best estimate of how long the customer will renew PCS. If there is no contractually stated renewal rate, the entire arrangement fee is recognized ratably over the relevant contractual PCS term beginning upon delivery of all elements other than PCS.

In certain multiple element arrangements, the Company is obligated to provide training services to customers related to the operation of the Company's software products. These training services are either provided to the customer on a “defined” basis (limited to a specified number of days or training classes) or on an “as-requested” basis (unlimited training over a contractual period).

For multiple element arrangements containing as-requested training obligations that are within the scope of the software revenue guidance, the Company recognizes the total arrangement consideration ratably over the contractual period during which the Company is required to “stand ready” to perform such training, provided that all other criteria for revenue recognition have been met.

For multiple element arrangements containing defined training obligations, the training services are typically provided to the customer prior to the completion of the installation services. For multiple element arrangements that are not within the scope of the software guidance, training is treated as a separate deliverable and recognized when delivered. For arrangements that are within the scope of the software revenue guidance, because revenue recognition does not commence until the completion of installation, the defined training obligations do not impact the timing of recognition of revenue. In certain circumstances in which training is provided after the end of the installation period, the Company commences revenue recognition upon the completion of training, provided that all other criteria for revenue recognition have been met.

In its multiple element arrangements the Company may offer a discount on future purchases of products and services. A discount is considered an additional element of an arrangement if the discount is considered more than insignificant. A more-than-insignificant discount with respect to future purchases is a discount that is: (i) incremental to the range of discounts reflected in the pricing of the other elements of the arrangement, (ii) incremental to the range of discounts typically given in comparable transactions, and (iii) significant. Insignificant discounts and discounts that are not incremental do not affect revenue recognition. If the discount is considered more than insignificant, then a portion of the fee received is deferred and recognized as revenue as the future purchases are made by the customer or upon expiration of the period that the discount is available.

Some of the Company's arrangements require significant customization of the product to meet the particular requirements of the customer. For these arrangements, revenue is typically recognized in accordance with the FASB's guidance for long-term construction type contracts using the POC method.

The determination of whether services entail significant customization requires judgment and is primarily based on alterations to the features and functionality to the standard release, complex or unusual interfaces as well as the amount of hours necessary to complete the customization solution relative to the size of the contract. Revenue from these arrangements is recognized on the POC method based on the ratio of total hours incurred to date compared to estimated total hours to complete the contract.

Management is required to make judgments to estimate the total estimated costs and progress to completion. Changes to such estimates can impact the timing of the revenue recognition period to period. The Company uses historical experience, project plans, and an assessment of the risks and uncertainties inherent in the arrangement to establish these estimates. Uncertainties in these arrangements include implementation delays or performance issues that may or may not be within the Company's control. If some level of profitability is assured, but the related revenue and costs cannot be reasonably estimated, then revenue is recognized to the extent of costs incurred until such time that the project's profitability can be estimated or the services have been completed. If the Company determines that based on its estimates its costs exceed the sales price, the entire amount of the estimated loss is accrued in the period that such losses become known.

The change in profit estimate of one BSS contract accounted for under the percentage of completion method negatively impacted income from operations by $14.8 million during the fiscal year ended January 31, 2013. Although there were no individually large profit estimate adjustments during fiscal year 2013, the fourth fiscal quarter ended January 31, 2014 was impacted by the recording of loss contract reserves of $7.1 million for three contracts accounted for under the Percentage of Completion method.

Revenue derived from sales to distributors, resellers, and value-added resellers are recognized when the resellers in turn sell the software product to their customers and installation of the software product has occurred, provided all other revenue recognition criteria are met. This is commonly referred to as the sell-through method. The contractual arrangements between the reseller and end user, or between the reseller and the Company, generally obligate the Company to provide services to the end user that are subject to end user acceptance. Further, payment terms are generally subject to the reseller's receiving payment from the end user and the end user's acceptance of the product. Therefore, the Company defers recognition until there is a “sell-through” by the reseller to an actual end user customer and acceptance by the end user.

In the consolidated and combined statements of operations, the Company classifies revenue as product revenue or service revenue. For multiple element arrangements that include both product and service elements, management evaluates various available indicators of fair value and applies its judgment to reasonably classify the arrangement fee between product revenue and service revenue. The amount of multiple element arrangement fees classified as product and service revenue based on management estimates of fair value when VSOE of fair value for all elements of an arrangement does not exist could differ from amounts classified as product and service revenue if VSOE of fair value for all elements existed. The allocation of multiple element arrangement fees between product revenue and service revenue, when VSOE of fair value for all elements does not exist, is for consolidated and combined financial statement presentation purposes only and does not affect the timing or amount of revenue recognized.

In determining the amount of a multiple element arrangement fee that should be classified between product revenue and service revenue, the Company first allocates the arrangement fee to product revenue and PCS (PCS is classified as service revenue) based on management's estimate of fair value for those elements. The remainder of the arrangement fee, which is comprised of all other service elements, is allocated to service revenue. The estimate of fair value of the product element is based primarily on management's evaluation of direct costs and reasonable profit margins on those products. This was determined to be the most appropriate methodology as the Company has historically been product-oriented with respect to pricing policies which facilitates the evaluation of product costs and related margins in arriving at a reasonable estimate of the product element fair value. Management's estimate of reasonable profit margins requires significant judgment and consideration of various factors, such as the impact of the economic environment on margins, the complexity of projects, the stability of product profit margins and the nature of products. The estimate of fair value for PCS is based on management's evaluation of the weighted-average of PCS rates for arrangements for which VSOE of fair value of PCS exists.

Post-Contract Customer Support Renewals

The Company's multiple element arrangements typically provide for renewal of PCS terms upon expiration of the original term. The amounts of these PCS renewals are recognized as revenue ratably over the specified PCS renewal period.

Professional Services Only Arrangements

Based on the type and nature of its professional-services-only arrangements, the Company recognizes revenue using either the proportional performance method, ratable recognition, completed performance method or on a time and materials basis. For fixed-fee arrangements recognized based on the proportional performance method, the Company typically measures progress to completion based on the ratio of hours incurred to total estimated project hours, an input method. For fixed-fee arrangements recognized based on the completed performance method, the Company recognizes revenue once the services are completed and there are no other obligations of the Company. The Company recognizes revenue for time and materials arrangements as the services are performed based on contractually stipulated billing rates.

Product and Service Costs

The Company's cost of revenue primarily consists of (i) material costs, (ii) compensation and related overhead expenses for personnel involved in the customization of its products, customer delivery and maintenance and professional services, (iii) contractor costs, (iv) royalties and license fees, (v) depreciation of equipment used in operations, and (vi) amortization of capitalized software costs and certain purchased intangible assets.

When revenue is recognized over multiple periods in accordance with the Company's revenue recognition policies, the material cost, including hardware and third party software license fees are deferred and amortized over the same period that product revenue is recognized. These costs are recognized as “Deferred cost of revenue” on the consolidated balance sheets. However, the Company has made an accounting policy election whereby the cost for installation and other service costs are expensed as incurred, except for arrangements recognized in accordance with the FASB's guidance for long-term construction type contracts.

For certain contracts where revenue is recognized in accordance with the FASB's guidance for long-term construction type contracts, revisions in estimates of costs are reflected in the accounting period in which the facts that require the revision become known. These costs include all direct material and labor costs and overhead related to contract performance.

Research and Development, Net

Research and development, net expenses primarily consist of personnel-related costs involved in product development and third party development and programming costs. Research and development costs are expensed as incurred.

A portion of the Company’s research and development operations are located in Israel, where certain of the Company’s subsidiaries derive benefits from participation in programs sponsored by the Government of Israel for the support of research and development activities in Israel. Certain of the Company’s research and development activities include projects partially funded by the Office of the Chief Scientist of the Ministry of Industry and Trade of the State of Israel (the “OCS”) under which the funding organization reimburses a portion of the Company’s research and development expenditures under approved project budgets. Although the Government of Israel does not own proprietary rights in the OCS-funded Products and there is no specific restriction by the OCS with regard to the export of the OCS-funded Products, under certain circumstances, there may be limitations on the ability to transfer technology, know-how and manufacturing of OCS-funded Products outside of Israel. Such limitations could result in the requirement to pay increased royalties or a redemption fee calculated according to the applicable regulations.

The Company’s gross research and development expenses for the fiscal years ended January 31, 2014, 2013 and 2012 were $67.6 million, $77.0 million and $94.3 million, respectively. Amounts reimbursable by the OCS and others for the fiscal years ended January 31, 2014, 2013 and 2012, were $0.1 million, $0.5 million and $0.1 million, respectively, which were recorded as a reduction to gross research and development expenses within “Research and development, net” in the consolidated and combined statements of operations.

Software Costs

Costs of software developed for internal use are capitalized in accordance with the FASB's guidance during the application development stage and are then amortized over the estimated useful life of the software, which to date has been five years or less once the software is ready for its intended use. These costs are included in “Property and equipment, net” in the consolidated balance sheets.

Sales and Marketing

Sales and marketing expenses include payroll, employee benefits, stock-based compensation, and other headcount-related expenses associated with sales and marketing personnel, and the costs of advertising, promotions and other programs. In addition, the Company's customer acquisition and origination costs, including sales and agent commissions are expensed when incurred, with the exception of certain sales referral fees that are capitalized and amortized ratably over the revenue recognition period. Advertising costs are expensed as incurred.

Stock-Based Compensation

Stock-based compensation expense is measured at the grant date based on the fair value of the award derived using the Black-Scholes option-pricing model and the cost is recognized as expense ratably over the award's vesting period, which generally vest ratably over two or three years and expire ten years from the date of grant. The Black-Scholes model requires making certain assumptions used within the model, the most significant of which are the stock price volatility assumption over the term of the awards and the expected life of the option award based on the actual and projected employee stock option behaviors. Other assumptions include the risk-free rate of return and dividends during the expected term.

The Company estimates expected forfeitures of stock-based awards at the grant date and recognizes compensation cost only for those awards expected to vest. Forfeiture rates are estimated based on historical experience of Comverse employees while employed by CTI prior to the Share Distribution. The forfeiture assumption is adjusted to the actual forfeitures that occur. Therefore, changes in the forfeiture assumptions may impact the amount and timing of the total amount of expense recognized over the vesting period. Estimated forfeitures are reassessed in subsequent periods and may change based on new facts and circumstances.

The fair value of equity instruments issued to a nonemployee is measured by using the stock price and other measurement assumptions as of the date earlier of either: (i) a commitment for performance by the nonemployee has been reached; or (ii) the counterparty's performance is complete. Expenses related to nonemployee awards are generally recognized in the same period and in the same manner as the Company incurs the related liability for goods and services received.

In connection with the Share Distribution, CTI's equity-based compensation awards held by the Company's employees were replaced with the Company's equity-based compensation awards on November 1, 2012. The replacement of CTI's equity-based compensation awards was considered a modification that resulted in a negligible increase in the fair value of the awards. The Company's combined statements of operations prior to the Share Distribution include expenses related to the Company's employee participation in the CTI plans.

APIC Pool

The long form method is used to determine the Company's pool of excess tax benefits available within additional paid-in capital. Excess tax benefits resulting from stock option exercises are recognized as additions to APIC in the period the benefit is realized. In the event of a shortfall (that is, the tax benefit realized is less than the amount previously recognized through periodic stock-based compensation expense recognition and related deferred tax accounting), the shortfall is charged against APIC to the extent of previous excess benefits, if any, including the hypothetical APIC pool, and then to tax expense.

Income Taxes

Income taxes are provided using the asset and liability method, such that income taxes (i.e., deferred tax assets, deferred tax liabilities, taxes currently payable/refunds receivable and tax expense/benefit) are recorded based on amounts refundable or payable in the current year and include the results of any difference between U.S. GAAP and tax reporting. Deferred income taxes reflect the tax effect of net operating losses, capital losses and general business credit carryforwards and the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial statement and income tax purposes, as determined under enacted tax laws and rates. Valuation allowances are established when management determines that it is more-likely-than-not that some portion or all of the deferred tax asset will not be realized. The financial effect of changes in tax laws or rates is accounted for in the period of enactment. The subsequent realization of net operating loss and general business credit carryforwards acquired in acquisitions accounted for using the acquisition method of accounting is recognized in the consolidated and combined statement of operations.

The Company was included in the CTI consolidated federal and certain combined state income tax returns until completion of the Share Distribution. As such, the Company was not a separate taxable entity for U.S. federal and certain state income tax purposes until completion of the Share Distribution. In addition, the Company did not have a written tax sharing agreement with CTI. The Company's provisions for income taxes and related balance sheet accounts were presented as if the Company were a separate taxpayer (“separate return method”). This method of allocating the CTI consolidated current and deferred income taxes was systematic, rational and consistent with the asset and liability method. The separate return method represented a hypothetical computation assuming that the reported revenue and expenses of the Company were incurred by a separate taxable entity. Accordingly, the reported provision for income taxes and the related balance sheet accounts (including but not limited to the NOL deferred tax assets) did not equal the amounts that were allocable to the Company under the applicable consolidated federal and state tax laws. Further, as the Company did not have a tax-sharing agreement with CTI in place, the expected payable was treated as a dividend to the parent.

From time to time, the Company has business transactions in which the tax consequences are uncertain. Significant judgment is required in assessing and estimating the tax consequences of these transactions. The Company prepares and files tax returns based on its interpretation of tax laws. In the normal course of business, the Company's tax returns are subject to examination by various taxing authorities. Such examinations may result in future tax, interest and penalty assessments. In determining the Company's tax provision for financial reporting purposes, the Company establishes a liability for uncertain tax positions unless such positions are determined to be more-likely-than-not of being sustained upon examination, based on their technical merits. That is, for financial reporting purposes, the Company only recognizes tax benefits that it believes are more-likely-than-not of being sustained and then recognizes the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. There is considerable judgment involved in determining whether positions taken on the tax return are more-likely-than-not of being sustained and determining the likelihood of various potential settlement outcomes.

The Company adjusts its estimated liability for uncertain tax positions periodically because of new information discovered as a function of ongoing examinations by, and settlements with, the various taxing authorities, as well as changes in tax laws, regulations and interpretations. The combined tax provision of any given year includes adjustments to prior year income tax accruals that are considered appropriate as well as any related estimated interest. The Company's policy is to recognize, when applicable, interest and penalties on uncertain tax positions as part of income tax expense (see Note 19, Income Taxes).

As part of the Company's accounting for business combinations, some of the purchase price is allocated to goodwill and intangible assets. Impairment expenses associated with goodwill are generally not tax deductible and will result in an increased effective income tax rate in the fiscal period any impairment is recorded. Amortization expenses associated with acquired intangible assets are generally not tax deductible pursuant to the Company's existing tax structure; however, deferred taxes have been recorded for non-deductible amortization expenses as a part of the purchase price allocation process. The Company has taken into account the allocation of these identified intangibles among different taxing jurisdictions, including those with nominal or zero percent tax rates, in establishing the related deferred tax liabilities. Under the FASB's guidance, the income tax benefit from future releases of the acquisition date valuation allowances or income tax contingencies, if any, are reflected in the income tax provision in the consolidated and combined statements of operations, rather than as an adjustment to the purchase price allocation.

Contingencies

Contingencies by their nature relate to uncertainties that require management to exercise judgment both in assessing the likelihood that a liability has been incurred as well as in estimating the amount of potential loss, if any. The Company accrues for costs relating to litigation, claims and other contingent matters when such liabilities become probable and reasonably estimable. Legal costs are expensed as incurred.

Restructuring

The Company has developed and implemented restructuring initiatives to improve efficiencies across the organization, reduce operating expenses, and better align its resources to market conditions. As a result of these plans, the Company has recorded restructuring expenses comprised principally of employee severance and associated termination costs related to the reduction of its workforce, office closures, losses on subleases and contract termination costs.

The Company recognizes a liability for costs associated with an exit or disposal activity when the liability is incurred, as opposed to when management commits to an exit plan. The Company measures the liabilities associated with exit and disposal activities at fair value. One-time termination benefits are expensed at the date the employees are notified, unless the employees must provide future services beyond a minimum retention period, in which case the benefits are expensed ratably over the future service periods.

Certain employees included in a termination plan may include employees in countries which require the Company by law to pay mandatory severance for involuntary termination based on years of service. A liability for the cost of the benefits would be recognized when payment is probable and estimable.

The Company recognizes a liability for office closures measured at its fair value when the Company ceases using the rights conveyed by the contract, based on the remaining lease rentals, adjusted for the effects of any prepaid or deferred items recognized under the lease. This liability is further reduced by estimated sublease rentals that could be reasonably obtained for the property regardless of the intention of the lessee to sublease the premises.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]	'
Recent Accounting Pronouncements	'
	RECENT ACCOUNTING PRONOUNCEMENTS
	The Company is currently classified as an emerging growth company and as such, can delay adopting new or revised accounting standards until such time as those standards apply to private companies. The Company has elected to follow the required adoption dates for private companies. Therefore, the adoption dates below reflect the Company's current classification.
	Standards Implemented
	In July 2012, the Financial Accounting Standards Board ("FASB") issued new accounting guidance on indefinite-lived intangible assets. The new guidance provides an entity the option first to assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more-likely-than-not that the indefinite-lived intangible asset is impaired. If, after assessing the totality of events and circumstances, an entity concludes that it is not more-likely-than-not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. However, if an entity concludes otherwise, then it is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount and recognize an impairment loss, if any, to the extent the carrying value exceeds its fair value. The guidance was effective for the Company for its annual impairment tests in the fiscal year ended January 31, 2014. The adoption of this guidance for the annual impairment test did not have any impact on its consolidated and combined financial statements.
	Standards To Be Implemented
	In February 2013, the FASB issued new accounting guidance on other comprehensive income. This topic will require the Company to provide information about the amounts reclassified out of accumulated other comprehensive income by component and the line items of net income to which significant amounts are reclassified. The guidance will be effective for the Company beginning February 1, 2014. The adoption of this guidance is anticipated to result in additional disclosures.

Expense Allocations and Share Distribution Agreements [Abstract]	'
Expense Allocations and Share Distribution Agreements	'
	EXPENSE ALLOCATIONS AND SHARE DISTRIBUTION AGREEMENTS
	Expense Allocations
	CTI provided a variety of services to the Company prior to the Share Distribution. CTI directly assigned, where possible, certain general and administrative costs to the Company based on actual use of those services. Where direct assignment of costs was not possible, or practical, CTI used other indirect methods to estimate the allocation of costs. Allocated costs include general support services such as information technology, legal services, human resource services, general accounting and finance, and executive support. Substantially all of these allocations are reflected in “Selling, general, and administrative” expenses in the Company’s combined statements of operations prior to the Share Distribution.
	Employee compensation and overhead expenses were allocated utilizing a time study of CTI employees’ percentage of time spent on Company-related matters. External vendor expenses were allocated based on information provided by the vendor or an internal analysis of benefits derived by the Company from the services incurred by CTI.
	The Company considered these expense allocations to be a reasonable reflection of the utilization of services provided. The allocations may not, however, reflect the expense the Company would have incurred as an independent company. Actual costs which may have been incurred if the Company had been an independent company for the fiscal years ended January 31, 2013 and 2012 would depend on a number of factors, including how the Company chose to organize itself, and what, if any, functions were outsourced or performed by the Company’s employees.
	The following table presents the expense allocations from CTI reflected in the Company’s consolidated and combined statements of operations:
		Fiscal Years Ended January 31,
		2013		2012
		(In thousands)
	Employee compensation expenses	$	2,623	$	6,665
	Overhead expenses and external vendor expenses	3,396		8,800
	Total	$	6,019	$	15,465
	Net Investment of CTI
	CTI primarily used a centralized approach for cash management and for financing of its operations with all related activity between the Company and CTI, reflected as equity transactions in “Net investment of CTI” in the combined statement of equity as of January 31, 2012. Intercompany transactions between the Company and CTI primarily included: (i) borrowings from CTI used to fund operations and capital expenditures, as well as repayment thereof and (ii) allocations of CTI’s corporate expenses identified above. As disclosed in Note 1, in connection with the Share Distribution, the Company recapitalized its Net Investment of CTI with the issuance of the Company's common stock.
	Certain loan arrangements between CTI and the Company that were not included in “Net investment of CTI” are disclosed in Note 11, Debt and Note 22, Related Party Transactions.
	Share Distribution Agreements
	The Company entered into a distribution agreement (the “Distribution Agreement”), transition services agreement, tax disaffiliation agreement and employee matters agreement (collectively, the “Share Distribution Agreements”) with CTI in connection with the Share Distribution. In particular, the Distribution Agreement, among other things, provides for the allocation between the Company and CTI of various assets, liabilities and obligations attributable to periods prior to the Share Distribution. Under the Distribution Agreement, the Company agreed to indemnify CTI and its affiliates (including Verint following the Verint Merger) against certain losses that may arise as a result of the Verint Merger and the Share Distribution. Certain of the Company's indemnification obligations are capped at $25.0 million and certain are uncapped. Specifically, the capped indemnification obligations include indemnifying CTI and its affiliates (including Verint after the Verint Merger) against losses stemming from breaches by CTI of representations, warranties and covenants in the Verint Merger Agreement and for any liabilities of CTI that were known by CTI but not included on the net worth statement delivered by CTI at the closing of the Verint Merger. The Company's uncapped indemnification obligations include indemnifying CTI and its affiliates (including Verint after the Verint Merger) against liabilities relating to the Company's business; claims by any shareholder or creditor of CTI related to the Share Distribution, the Verint Merger or related transactions or disclosure documents; certain claims made by employees or former employees of CTI and any claims made by employees and former employees of the Company (including but not limited to the Israeli optionholder suits discussed in Note 24, Commitments and Contingencies); any failure by the Company to perform under any of the agreements entered into in connection with the Share Distribution; claims related to CTI's ownership or operation of the Company; claims related to the Starhome Disposition; certain retained liabilities of CTI that are not reflected on or reserved against on the net worth statement delivered by CTI at the closing of the Verint Merger; and claims arising out of the exercise of appraisal rights by a CTI shareholder in connection with the Share Distribution. On February 4, 2013, in connection with the closing of the Verint Merger Agreement, CTI placed $25.0 million in escrow to support indemnification claims to the extent made against the Company by Verint and any cash balance remaining in such escrow fund 18 months after the closing of the Verint Merger, less any claims made on or prior to such date, will be released to the Company. The escrow funds cannot be used for claims related to the Israeli optionholder suits. Although no indemnification claims have been filed and the Escrow Release Date is within 12 months of January 31, 2014, the Company continues to classify the restricted cash balance as "Long-term restricted cash" in the Consolidated Balance Sheets until it can be determined if any future claims would restrict the release of such escrow funds. The Company also assumed all pre-Share Distribution tax obligations of each of the Company and CTI.
	The Company and CTI entered into a tax disaffiliation agreement that governs their respective rights, responsibilities and obligations after the Share Distribution with respect to tax liabilities and benefits, tax attributes, tax contests and other tax matters regarding income taxes, other taxes and related tax returns. The Company and CTI also entered into an employee matters agreement, which allocates liabilities and responsibilities relating to employee compensation and benefit plans and programs.

	-1	The goodwill associated with Comverse MI, previously included in Comverse Other, was impaired during the fiscal year ended January 31, 2013.
	-2	The goodwill associated with Netcentrex, previously included in Comverse Other, was impaired during the fiscal year ended January 31, 2009 and prior fiscal years.
	The Company tests goodwill for impairment annually as of November 1 or more frequently if events or circumstances indicate the potential for an impairment exists. Under the Company's current segment structure, the BSS and Digital Services segments have been evaluated and it has been determined that for each segment the fair value significantly exceeds the book value.
	During the fiscal year ended January 31, 2013, Comverse MI, previously included in Comverse Other, experienced intensified competition, price erosion, and significant decline in capacity upgrades from existing customers, resulting in an impairment charge of approximately $5.6 million during the fiscal year ended January 31, 2013.
	The Company used the adjusted net asset value method to determine the fair value of Comverse MI. Within this method, the Company estimated the amount a market participant would be willing to pay for each of the individual assets of the Comverse MI, net of liabilities. The Company's estimate was based on a number of subjective factors, including: (i) the realizable value resulting from the sale of accounts receivables and inventory, and fixed assets, (ii) the magnitude and timing of future revenue streams associated with Comverse MI's technology and trademarks, and (iii) an estimated discount rate with which to calculate the net present value of forecasted cash flows.

	The Company entered into derivative arrangements to manage a variety of risk exposures during the fiscal years ended January 31, 2014, 2013 and 2012, including foreign currency risk related to forecasted foreign currency denominated payroll costs. The Company assesses the counterparty credit risk for each party prior to entering into its derivative financial instruments and in valuing the derivative instruments for the periods presented.
	Forward Contracts
	During the fiscal years ended January 31, 2014, 2013 and 2012, the Company entered into a series of short-term foreign currency forward contracts to limit the variability in exchange rates between the U.S. dollar (the “USD”) and the new Israeli shekel (“NIS”) to hedge probable cash flow exposure from expected future payroll expense. The transactions qualified for cash flow hedge accounting under the FASB’s guidance and there was no hedge ineffectiveness. Accordingly, the Company recorded all changes in fair value of the forward contracts as part of other comprehensive income (loss) in the consolidated and combined statement of comprehensive loss. Such amounts are reclassified to the consolidated and combined statements of operations when the effects of the item being hedged are recognized. The Company’s derivatives outstanding as of January 31, 2014 are short-term in nature and are due to contractually settle within the next twelve months.

	FAIR VALUE MEASUREMENTS
	Assets and Liabilities Measured at Fair Value on a Recurring Basis
	The fair value of financial instruments is estimated by the Company, using available market information and appropriate valuation methodologies. However, considerable judgment is required in interpreting market data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts that the Company could realize in a market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.
	Commercial paper. The Company uses quoted prices for similar assets and liabilities.
	Money Market Funds. The Company values these assets using quoted market prices for such funds.
	Derivative assets. The fair value of derivative instruments is based on quotes or data received from counterparties and third party financial institutions. 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 markets rates for similar contracts using readily observable market prices thereof.
	The following tables present financial instruments according to the fair value hierarchy as defined by the FASB’s guidance:

As of January 31, 2013, $9.4 million of commercial paper and $38.5 million of money market funds were classified in “Cash and cash equivalents” within the consolidated balance sheet.
	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, the Company also measures certain assets and liabilities at fair value on a nonrecurring basis. The Company measures non-financial assets, classified within Level 3 of the fair value hierarchy, including goodwill, intangible assets and property and equipment, at fair value when there is an indication of impairment. These assets are recorded at fair value only when an impairment expense is recognized. The Company has elected not to apply the fair value option for non-financial assets and non-financial liabilities. For further details regarding impairment reviews, see Note 1, Organization, Business and Summary of Significant Accounting Policies.
	During the fiscal year ended January 31, 2013, the Company recorded a goodwill impairment charge of approximately $5.6 million. The Company used the adjusted net asset value method to determine the fair value of Comverse MI, which previously was a reporting unit within Comverse Other, including unobservable inputs classified as Level 3 within the fair value hierarchy. Within this method, the Company estimated the amount a market participant would be willing to pay for each of the individual assets of Comverse MI, net of liabilities (see Note 6, Goodwill).
	The carrying amounts of cash and cash equivalents, restricted cash and bank time deposits, accounts receivable and accounts payable are reasonable estimates of their fair value.

	Other long-term liabilities	12,804				6,250
	Total	$	147,942			$	168,876
	Under Israeli law, the Company is obligated to make severance payments under certain circumstances to employees of its Israeli subsidiaries on the basis of each individual’s current salary and length of employment. The Company’s liability for severance pay is calculated pursuant to Israel’s Severance Pay Law based on the most recent monthly salary of the employee multiplied by the number of years of employment, as of the balance sheet date. The liability for severance pay is recognized as compensation benefits in the consolidated and combined statements of operations. Employees are entitled to one month’s salary for each year of employment or a portion thereof.  The Company records the obligation as if it was payable at each balance sheet date (“shut-down method”).  A portion of such severance liability is funded by monthly deposits into insurance policies, which are restricted to only be used to satisfy such severance payments. Any change in the fair value of the asset is recognized as an adjustment to compensation expense in the consolidated and combined statements of operations. The asset and liability are recognized gross and not offset on the consolidated balance sheet. Upon involuntary termination, employees will receive the balance from deposited funds from the insurance policies with the remaining balance paid by the Company. For voluntarily termination the employees are entitled, based on Company's policy, to the balance in the deposited funds. Any remaining net liability balance is reversed as compensation benefits in the consolidated and combined statements of operations.
	For employees in Israel hired after January 2011, the Company makes regular deposits with certain insurance companies for accounts controlled by each applicable employee in order to secure the employee's rights upon termination. The Company is relieved from any severance pay liability with respect to deposits made on behalf of each employee. As such, the severance plan is only defined by the monthly contributions made by the Company, the liability accrued in respect of these employees and the amounts funded are not reflected in the Company's balance sheets. The portion of liability not funded is included in Other liabilities in the consolidated balance sheets.
	A portion of such severance liability is funded by monthly deposits into insurance policies, which are restricted to only be used to satisfy such severance payments. The amount of deposits is classified in “Other assets” within the consolidated balance sheets as severance pay fund in the amounts of $33.5 million and $36.3 million as of January 31, 2014 and 2013, respectively.

Stock-Based Compensation	'
	STOCK-BASED COMPENSATION
	Comverse, Inc. 2012 Stock Incentive Compensation Plan
	In October 2012, in connection with the Share Distribution the Company adopted the Comverse, Inc. 2012 Stock Incentive Compensation Plan (the "2012 Incentive Plan"). The following is a summary of the material terms of the 2012 Incentive Plan.
	The 2012 Incentive Plan provides for the issuance of nonqualified stock options, incentive stock options, stock appreciation rights, restricted stock and other stock-based awards (referred to collectively as the "Awards") based on shares of the Company's common stock (referred to as "Shares"). The Company's employees, non-employee directors and consultants as well as employees and consultants of its subsidiaries and affiliates are eligible to receive Awards.
	A total of 2.5 million Shares are reserved for issuance under future Awards to be granted under the 2012 Incentive Plan following the effective date of the plan (referred to as the "Future Awards"). As of January 31, 2014, an aggregate of 1.8 million Future Awards are available for grant under the plan.
	The 2012 Incentive Plan is scheduled to terminate in October 2022. Options will be designated as either nonqualified stock options or incentive stock options. An option granted as an incentive stock option will, to the extent it fails to qualify as an incentive stock option, be treated as a nonqualified option. The exercise price of an option, either incentive stock option or nonqualified stock options, may not be less than the fair market value of underlying shares on the date of grant, except for individuals who hold a 10% or more interest in the Company, for whom the exercise price of any Future Award may not be less than 110% of the share price. The term of each option may not exceed ten years (or, in the case of an incentive stock option granted to a 10% shareholder, five years). The maximum number of shares with respect to which any options may be granted to any grantee in any consecutive twelve (12) month period shall be 300,000 shares. In addition, the maximum number of shares with respect to which any stock appreciation rights may be granted to any grantee in any consecutive twelve (12) month period shall be 300,000 shares. The maximum amount of compensation under an award that is intended to constitute “qualified performance-based compensation” within the meaning of Section 162(m) of the Internal Revenue Code (“Performance-Based Compensation Awards”) (other than options and stock appreciation rights) granted to any grantee in any consecutive twelve (12) month period shall be 150,000 shares and the maximum amount of Performance-Based Compensation Awards granted to any grantee in any consecutive twelve (12) month period shall be $10,000,000 if such Performance-Based Compensation Awards are denominated in cash rather than shares.
	Replacement of CTI's Equity-Based Compensation Awards
	Pursuant to the terms of the Share Distribution, certain awards that were previously granted under CTI's stock incentive plan to the Company's employees and consultants have been replaced by awards that relate to the Company's common stock and have been assumed by the 2012 Incentive Plan (referred to as the "Assumed CTI Awards"). A total of 5.0 million Shares were reserved for issuance under the Assumed CTI Awards. Such reserved Shares may only be issued pursuant to the Assumed CTI Awards and may not be issued pursuant to any Future Awards. In connection with the Share Distribution, the Company issued 857,280 restricted stock units and 495,894 options to purchase shares of the Company's common stock to replace CTI Awards previously granted to the Company's employees. The treatment of the Assumed CTI Awards held by the Company's employees and consultants is described below.
	Stock Option Awards
	CTI options held by the Company's employees were replaced on November 1, 2012 with options for shares of the Company's common stock as described below, based on whether the CTI options had an exercise price that was (a) less than $10.52 per share (referred to as the "Group A options") or (b) equal to or greater than $10.52 per share (referred to as the "Group B options").
	The exercise price of the Group A options was adjusted such that the exercise price equaled one hundred percent (100%) of the published closing trading price of a share of the Company's common stock on the NASDAQ Stock Exchange on November 1, 2012. The number of shares of the Company's common stock subject to the Group A options was adjusted such that for each award, the aggregate Black-Scholes value of the Group A options immediately after the Share Distribution date was equal to the aggregate Black-Scholes value of the Group A options immediately before the Share Distribution date. The adjusted Group A options have a new term of ten years beginning on November 1, 2012. Any fractional shares resulting from the adjustment were rounded down to the nearest whole share. All other terms of the Group A options remained the same, including continued vesting pursuant to the current terms of the awards.
	The exercise price of the Group B options was adjusted such that the exercise price equaled two hundred percent (200%) of the published closing trading price of a share of the Company's common stock on the NASDAQ Stock Exchange on November 1, 2012. The number of shares of the Company's common stock subject to the Group B options was adjusted such that for each award the aggregate Black-Scholes value of the Group B Options immediately after the Share Distribution date was equal to the aggregate Black-Scholes value of the Group B options immediately before the Share Distribution date. The adjusted Group B options have a remaining term that is the same as the existing option term. Any fractional shares resulting from the adjustment were rounded down to the nearest whole share. All other terms of the Group B options remain the same, including continued vesting pursuant to the current terms of the awards.
	CTI options that were “in the money,” (i.e., where the exercise price is less than the trading price of the CTI stock) were replaced in a manner that preserved the aggregate in-the-money value and the ratio of exercise price to fair-market value of such options. All other terms of the in the money options remain the same, including continued vesting, and time to expiration, pursuant to the current terms of the awards.
	The replacement of CTI's equity-based compensation awards was considered a modification of an award. As a result, the Company compared the fair value of the awards immediately prior to the Share Distribution to the fair value of the awards immediately after the Share Distribution to measure incremental compensation cost. The modification resulted in an increase in the fair value of the awards. The amount of non-cash compensation expense was negligible.
	The following table presents CTI options held by the Company's employees and officers as of the Share Distribution date and the number of replacement options granted under the 2012 Incentive Plan:
	Option	CTI's options			Replacement options granted under 2012 Plan
	Group A options	374,800			77,526
	Group B options	1,716,978			70,881
	In the money options	1,533,699			347,487
	Total options	3,625,477			495,894
	Unvested Restricted Stock Units (RSUs) and Unvested Deferred Stock Units (DSUs)
	On November 1, 2012, unvested CTI RSUs and unvested CTI DSUs held by the Company's officers and employees were replaced with the Company's RSUs. Following the Share Distribution date, the number of shares of the Company's common stock underlying the replaced RSUs was equal to (1) the number of CTI common shares underlying the CTI RSUs and CTI DSUs held as of the Share Distribution date multiplied by (2) a ratio, the numerator of which was equal to the published closing trading price of a CTI common share on the NASDAQ Stock Exchange (traded the “regular way”) on the day prior to the Share Distribution date and, the denominator of which was equal to the published closing trading price of a share of the Company's common stock on the NASDAQ Stock Exchange on November 1, 2012. In lieu of issuing fractional RSUs, a cash payment equal to the value of the fractioned share was made to the holders by the Company. All other terms and conditions of the Company's RSUs remain the same, including continued vesting pursuant to the current terms of the awards.
	The following table presents CTI's RSUs and DSUs held by the Company's employees and officers as of the Share Distribution date and the number of replacement RSUs granted under the 2012 Incentive Plan:
	Stock units	CTI's stock units			Replacement restricted stock units under the 2012 Incentive
	RSUs	3,200,339			724,807
	DSUs	584,667			132,473
	Total	3,785,006			857,280
	Company Share-Based Awards
	Stock-based compensation expense associated with awards made by the Company, as well as historically allocated stock-based compensation expense from CTI, included in the Company’s consolidated and combined statements of operations are as follows:
			Fiscal Years Ended January 31,
			2014				2013				2012

	Stock-based compensation expense associated with awards granted to Starhome's employees is included in discontinued operations and therefore not presented in the table above. For the fiscal years ended January 31, 2013 and 2012, such stock-based compensation expense was $0.5 million and $0.4 million, respectively.
	Restricted Awards and Stock Options
	The Company grants restricted stock unit awards and deferred stock unit awards subject to vesting provisions (collectively, “Restricted Awards”) to certain key employees and directors. For the fiscal years ended January 31, 2014 and 2013, the Company granted Restricted Awards valued at $9.8 million and $0.8 million, respectively, based on the fair market value of the Company’s common stock on the date of grant. The Company grants stock options to certain key employees. For the fiscal years ended January 31, 2014 and 2013, the Company granted stock options valued at $3.1 million and $0.4 million, respectively, based on the grant date fair value.
	Included in the grants of restricted stock awards are certain awards that vest subject to certain performance-based criteria. During the fiscal year ended January 31, 2014, performance-based awards of restricted stock units for the issuance of 116,279 shares of common stock, with a fair value of $3.4 million, were granted to certain executive officers and employees of the Company. These grants will vest upon achievement of prescribed performance milestones and service requirements of two years for vesting. During the fiscal year ended January 31, 2014, 34,884 shares have been forfeited due to prescribed performance milestones not being achieved. As of January 31, 2014, the remainder of the performance shares have milestone that have been or are probable of being achieved.
	As of January 31, 2014, 754,349 stock options to purchase the Company’s common stock and 656,141 Restricted Awards were outstanding, of which 81,395 shares were performance-based awards. There were 1,811,375 shares available for future grant under the 2012 Incentive Plan as of January 31, 2014.

Fair Value Assumptions
The Company estimated the fair value of stock options on the date of grant or modification utilizing the Black-Scholes option valuation model. Assumptions for all grants and significant modifications are detailed below.
The fair value assumptions for stock options granted during the fiscal year ended January 31, 2014 and three months ended January 31, 2013 (subsequent to the Share Distribution), were as follows:
		Fiscal Years Ended January 31, 2014				Three Months Ended January 31, 2013
Risk-Free Rate		0.77% - 1.27%				0.47		%
Volatility		37.37% - 43.72%				50.1		%
Expected Term (years)		4				4
Market Value		$29.00 - $38.87				$	28.23
Weighted-average estimated fair value of options granted during the year		$	8.93			$	10.99
Grant date fair value of stock options vested (in millions)		$	1.1			$	—
Intrinsic value of all options exercised (in millions)		$	0.2			$	0.02
The Company based the risk-free interest rate on the implied yields on U.S. Treasury zero-coupon issues with an equivalent remaining term at the time of grant.
The expected term in years represents the period of time that the awards granted are expected to be outstanding based on historical experience of Comverse employees while employed by CTI prior to the Share Distribution. The assumption for dividend yield is zero because the Company has not historically paid dividends nor does it expect to do so in the foreseeable future.
The following table summarizes the activities for our unvested RSUs for the year ended January 31, 2014:
		Unvested Restricted Awards
		Shares			Weighted
					Average Modified/Grant
					Price
Unvested balance, January 31, 2013		838,560			$	29.03

	DISCONTINUED OPERATIONS
	Starhome was a CTI subsidiary (66.5% owned as of January 31, 2012). On September 19, 2012, CTI, in order to ensure it could meet the conditions of the Verint Merger, contributed to the Company its interest in Starhome, including its rights and obligations under the Starhome Share Purchase Agreement discussed below. The Starhome Disposition was completed on October 19, 2012.
	Under the terms of the Starhome Share Purchase Agreement, Starhome’s shareholders received aggregate cash proceeds of approximately $81.3 million, subject to adjustment for fees, transaction expenses and certain taxes. Of this amount, $10.5 million is held in escrow to cover potential post-closing indemnification claims, with $5.5 million being released after 18 months and the remainder released after 24 months, in each case, less any claims made on or prior to such dates. The Company received aggregate net cash consideration (including $4.9 million deposited in escrow at closing) of approximately $37.2 million, after payments that CTI agreed to make to certain other Starhome shareholders of up to $4.5 million. The escrow funds are available to satisfy certain indemnification claims under the Starhome Share Purchase Agreement to the extent that such claims exceed $1.0 million. As of January 31, 2014, such claims have not exceeded the $1.0 million threshold.
	The Company and Starhome shareholders have made customary representations and warranties and covenants in the Starhome Share Purchase Agreement, including an agreement not to solicit Starhome employees or interfere with Starhome’s clients, customers, suppliers, licensor's or other business relationships for a period of four years following the closing. The Company has also agreed for a period of four years following the closing (October 19, 2012) that it will not, and will cause its affiliates not to, create, design, develop or offer for sale any product or service which directly competes with any products or services offered by Starhome, subject to certain limited exceptions. In addition, as contemplated by the Starhome Share Purchase Agreement, Starhome and the Company entered into a transition services agreement at the closing of the Starhome Disposition.
	The Company did not have significant continuing involvement in Starhome's operations following the closing of the Starhome Disposition, and accordingly, the results of operations of Starhome are included in discontinued operations, less applicable income taxes, as a separate component of net loss in the Company's consolidated and combined statements of operations for the fiscal years ended January 31, 2013 and 2012.
	Starhome's results of operations included in discontinued operations were as follows:

	The Company and Starhome had previously entered into transactions pursuant to which the Company performed certain production, support and maintenance services for Starhome, and these transactions continue following the completion of the Starhome Disposition. The Company does not consider these transactions to be significant. The Company recognized revenue related to transactions with Starhome of $3.0 million and $3.1 million and cost of revenue of $0.3 million and $1.4 million for the nine months ended October 31, 2012 and the fiscal year ended January 31, 2012, respectively.
	Subsequent to the Starhome Distribution, the Company recognized revenues related to transactions with Starhome of $1.3 million for the fiscal year ended January 31, 2014 and recognized revenues of $1.0 million for the three months ended January 31, 2013.

	EARNINGS (LOSS) PER SHARE ATTRIBUTABLE TO COMVERSE, INC.'S STOCKHOLDERS
	Basic earnings (loss) per share attributable to the Company’s stockholders for the fiscal years ended January 31, 2014, 2013 and 2012 is computed using the weighted average number of shares of common stock outstanding. For purposes of computing diluted earnings (loss) per share attributable to the Company’s stockholders, shares issuable upon exercise of stock options and deliverable in settlement of unvested RSU awards are included in the weighted average number of shares of common stock outstanding, except when the effect would be antidilutive.
	The calculation of earnings (loss) per share attributable to Comverse, Inc.’s stockholders is as follows:

	Diluted earnings (loss) per share	$	0.83	$	0.23		$	(0.71	)
	The computation of basic and diluted loss per share for the fiscal year ended January 31, 2012 is calculated using the number of shares of the Company's common stock outstanding on October 31, 2012, following the Share Distribution. For the fiscal year ended January 31, 2012, there are no dilutive shares as there were no actual shares or share-based awards outstanding for Comverse, Inc. prior to the Share Distribution.
	As a result of the Company's net loss from continuing operation in the fiscal year ended January 31, 2013, the diluted earnings per share calculation excludes 0.3 million shares of stock-based awards from the calculation because their inclusion would have been anti-dilutive.
	The computation of the Company's diluted earnings per share for the fiscal year ended January 31, 2014 excludes 0.7 million shares of stock-based awards from the calculation because their inclusion would have been anti-dilutive.

	INCOME TAXES
	The Company's operating results have historically been included in CTI's consolidated U.S. federal and state income tax returns. The Company's non-U.S. operations had primarily been conducted separate from CTI. For purposes of the Company's combined financial statements pre-Share Distribution, the provision for income taxes, taxes payable and deferred income tax balances had been recorded as if the Company had filed all tax returns on a separate return basis (“hypothetical carve-out basis”) from CTI. Post-Share Distribution, the provision for income taxes, taxes payable and deferred income tax balances are recorded in accordance with the Company's stand-alone income tax positions.
	During the nine months ended October 31, 2013, the Company's income tax balances which had been previously presented on a hypothetical carve-out basis at January 31, 2013 were adjusted to reflect the Company's post-Share Distribution stand-alone income tax positions, including those related to unrecognized tax benefits, tax loss and credit carry forwards, other deferred tax assets and valuation allowances. These post-Share Distribution adjustments resulted in a $6.1 million increase in income taxes payable and a $2.6 million decrease in net deferred tax assets including valuation allowances which were offset by an $8.7 million increase in accumulated deficit.
	The Company and CTI have entered into an agreement that governs their respective rights, responsibilities and obligations after the Share Distribution with respect to tax obligations, tax attributes, tax contests and other tax matters regarding income taxes, other taxes and related tax returns. The agreement provides that the Company will be responsible for all tax obligations with respect to periods before the Share Distribution. After October 31, 2013, the Company has recorded income tax obligations of CTI, in addition to those of the Company.
	On September 19, 2012, CTI, in order to ensure it could meet the conditions of the Verint Merger, contributed to the Company its interest in Starhome, including its rights and obligations under the Starhome Share Purchase Agreement. The Company recorded a deferred tax asset and related valuation allowance of approximately $12.4 million at the time of the contribution. The Starhome Disposition was completed on October 19, 2012 and the deferred tax asset and related valuation allowance were reversed through income from discontinued operations, net of tax.
	As part of the remediation effort for the Company's material weakness in income taxes, during the fourth quarter of fiscal 2013 the Company identified and corrected via an adjustment of income tax expense, overstatements of its accruals made in prior years for uncertain tax positions related to federal and state income tax returns for the periods from 2005 to 2012. The correction resulted in a $4.8 million reduction of its uncertain tax positions (see Note 14, Other Long-Term Liabilities) and a reduction in income tax expense as of and for the year ended January 31, 2014. The $4.8 million reduction in income tax expense was partially offset by the correction of an overstatement of the Company’s withholding tax assets related to foreign withholdings which totaled $1.2 million for the periods from 2010 to 2012.

	The significant differences that impact the effective tax rate relate to changes to the valuation allowance, tax credit, tax contingencies, the difference between the U.S. federal statutory rate and the rates in foreign jurisdictions, the U.S. tax effect on foreign earnings and withholding taxes.
	The Company's operations in Israel have been approved as an “Approved Enterprise” pursuant to programs administered by the Investment Center of the Israeli Ministry of Industry, Trade and Labor. Further, at the time the Company filed its 2012 Israeli tax return, the Company made an election for a “Benefited Enterprise” program. Under these programs, the Company is eligible for tax benefits under the Israeli Law for Encouragement of Capital Investments, 1959. Under the terms of these programs, subject to certain prescribed conditions, income attributable to each Enterprise is exempt from income tax for a period of two years and is subject to a reduced income tax rate for the subsequent five to 15 years (generally 10%-15%, depending on the percentage of foreign (non-Israeli) investment in the Company). The Company was notified that it is no longer meeting the research and development investment condition which relates to these programs. As a result, the tax benefits under the “Approved Enterprise” program were reduced and the “Benefited Enterprise” program will most likely not become effective. When the “Benefited Enterprise” program is not in effect and when the other “Approved Enterprise” programs expire, an alternative income tax rate of 16% can be requested from the authorities within the “Preferred Enterprise” path under the Law for Encouragement of Capital Investments, 1959. The changes in tax rate, prompted by the notice referred to above, to 13.57% - 16% were reflected in the Company’s financial statements during the fourth quarter of the fiscal year ended January 31, 2014 resulting in an increase in net deferred tax items and an offsetting valuation allowance of $43.7 million as of January 31, 2014. This tax rate change has been reflected in the effective income tax rate reconciliation above and had no net impact on Income Tax Expense for the fiscal year ended January 31, 2014.
	During the three months ended January 31, 2013, the Company received a tax refund from the State of Israel of $24.8 million, including interest of $6.0 million. The interest refunded was recognized in the Statements of Operations upon receipt due to the uncertainty of collectability. Comverse's accounting policy is to record interest income on tax payments in tax expense in the statements of operations.
	Deferred income taxes are provided for the effects of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and the amounts recognized for income tax purposes. Significant components of the Company’s deferred tax assets and deferred tax liabilities are as follows:
		As of Fiscal Years Ended January 31,
		2014			2013

	Deferred tax assets:

U.S. income and foreign withholding taxes have not been recorded on permanently reinvested earnings of certain subsidiaries aggregating $182.3 million as of January 31, 2014. At this time, determination of the amounts of deferred U.S. federal and state income taxes and foreign withholding taxes related to these earnings is not practicable. As of January 31, 2014, $149.0 million of earnings from certain subsidiaries are not considered to be permanently reinvested and therefore, foreign withholding taxes of $20.1 million have been accrued. A portion of the earnings of subsidiaries in the following countries are not considered permanently reinvested: Australia, Israel, Brazil, Canada, Hong Kong, New Zealand, Mexico, Portugal, Netherlands, and the United Kingdom.
The Company has net operating loss carryforwards (“NOLs”) for tax purposes and other deferred tax benefits that are available to offset future taxable income.
The Company’s gross NOLs for tax return purposes are as follows:
	Fiscal Years Ended January 31,
	2014			2013
	(In thousands)
U.S. Federal NOLs	$	459,784		$	362,273
U.S. State NOLs	326,938			253,790
Foreign NOLs	813,203			798,746
The U.S. federal NOL carry forwards expire in various years ending from January 31, 2016 to January 31, 2032. The U.S. state NOL carry forwards expire in various years ending from January 31, 2015 to January 31, 2031. At January 31, 2014, all but $9.4 million of the foreign NOLs have indefinite carryforward periods. The table above reflects gross NOLs for tax return basis which are different from financial statement NOLs, primarily due to the reduction of the financial statement NOLs under the FASB's guidance on accounting for uncertainty in income taxes. The Company has U.S. federal, state and foreign tax credit carryforwards of approximately $50.3 million and $63.5 million as of January 31, 2014 and 2013, respectively. The utilization of these carryforwards is subject to limitations. The federal AMT credit has no expiration date. The foreign tax credit carryforwards expire in various years ending from January 31, 2015 to 2018.
In accordance with the FASB’s guidance relating to accounting for uncertainty in income taxes the Company recognizes unrecognized tax benefits in non-current tax liabilities. The following table reconciles the amounts recorded for unrecognized tax benefits for the fiscal years ended January 31, 2014, 2013 and 2012:
	Fiscal Years Ended January 31,
	2014			2013			2012
	(In thousands)
Gross unrecognized tax benefits as of February 1	$	278,602		$	287,846		$	280,703
Increases related to tax positions taken in prior years	29,520			4,151			6,636
Decreases related to tax positions taken in prior years	(11,671		)	(14,665		)	(2,549		)
Increases related to tax positions in current year	5,970			6,835			12,769
Decreases related to tax positions in current year	—			—			—
Decreases due to settlements with taxing authorities	(1,500		)	(2,985		)	(369		)

Increases (decreases) related to foreign currency exchange rate fluctuations	1,325			(440		)	(3,325		)
Gross unrecognized tax benefits as of January 31	$	301,174		$	278,602		$	287,846
The balances of unrecognized tax benefits as of January 31, 2014, 2013 and 2012 are $301.2 million, $278.6 million and $287.8 million of which $90.5 million, $104.2 million and $95.2 million represent the amounts that, if recognized, may impact the effective income tax rate in future periods.
The Company recognized interest and penalties related to unrecognized tax benefits in its income tax expense. As of January 31, 2014 and 2013, the Company accrued $39.2 million and $51.1 million for interest and penalties, respectively.
The Company estimates that it is reasonably possible that the balance of unrecognized tax benefits as of January 31, 2014 may decrease by approximately $1.3 million in the next twelve months, as a result of lapse of statutes of limitation and settlements with tax authorities. These unrecognized tax benefits relate to permanent establishment and other tax positions in the amounts of $0.6 million and $0.8 million, respectively.
The significant tax jurisdictions in which the Company is currently under examination by tax authorities include Canada, India, Indonesia, Israel and United Kingdom. The Company anticipates that it is reasonably possible that new tax matters could be raised by tax authorities that may require increases or decreases to the balance of unrecognized tax benefits; however, an estimate of such increases or decreases cannot be made.
The Company files income tax returns in the U.S. federal, various state and local, and foreign tax jurisdictions. As of January 31, 2014, the Company has open tax years which can be subject to tax audit (and in some cases are under tax audit) in the following major jurisdictions:
Jurisdiction	Tax Years Ended
United States	January 31, 1999 - January 31, 2014
Israel	January 31, 2006 - January 31, 2014
United Kingdom	December 31, 2005 - January 31, 2014
India	March 31, 2002 - March 31, 2013
France	January 31, 2008 - January 31, 2014
Brazil	December 31, 2004, December 31, 2009 - December 31, 2013
Canada	January 31, 2007 - January 31, 2014
Various U.S. States	January 31, 1999 - January 31, 2014
The Company regularly assesses the adequacy of its provisions for income tax contingencies in accordance with the FASB's guidance. As a result, the Company may adjust the liabilities for unrecognized 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 limitations.
The Company maintains valuation allowances in jurisdictions where it is more-likely-than-not that all or a portion of a deferred tax asset may not be realized. In determining whether a valuation allowance is warranted, the Company evaluates factors such as prior earnings history, expected future earnings, reversal of existing taxable temporary differences, carry-back and carry-forward periods and tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset. Changes in valuation allowances are included in the Company's tax provision in the period of change except for items related to additional paid-in capital. During the fiscal year ended January 31, 2014, the Company recorded an increase of $71.1 million to its valuation allowance related primarily to net operating losses in the U.S. and foreign jurisdictions and other changes related to the effects of the Tax Disaffiliation Agreement entered into in connection with the Share Distribution.
The Company’s activity in the valuation allowance is as follows:

Segment Reporting [Abstract]	'
Business Segment Information	'
	BUSINESS SEGMENT INFORMATION
	The Company’s reportable segments consist of BSS and Digital Services. The results of operations of the Company’s global corporate functions that support its business units are included in the column captioned “All Other” as part of the Company’s business segment presentation. The Company does not maintain balance sheets for its operating segments.
	Historically, Mobile Internet (“Comverse MI”), which was renamed Policy and is responsible for the Company's mobile Internet and policy products, and Netcentrex, an IP-based solution that provides carrier-hosted enterprise and consumer IP services, were included in All Other. Effective in the fourth quarter of fiscal 2013, Comverse MI and Netcentrex have been combined with the Comverse BSS and Comverse VAS segments, respectively, to form “BSS” and “Digital Services” segments. The change in segment reporting aligns with information reviewed by the Company's CODM, a change in management structure and the convergence of operations to take advantage of potential synergies. Accordingly, the results presented under segment reporting reflect the change in segment reporting for all periods presented to conform to the current period segment reporting structure. The change in segment reporting does not affect the Company’s previously reported consolidated and combined financial statements.
	Starhome results of operations are included as discontinued operations and therefore are not presented in segment information.
	Segment Performance
	The Company evaluates its business by assessing the performance of each of its operating segments. The Company’s Chief Executive Officer is its CODM. The CODM uses segment performance, as defined below, as the primary basis for assessing the financial results of the operating segments and for the allocation of resources. Segment performance, as the Company defines it in accordance with the FASB’s guidance relating to segment reporting, is not necessarily comparable to other similarly titled captions of other companies.
	Segment performance is computed by management as income (loss) from operations adjusted for the following: (i) stock-based compensation expense; (ii) amortization of intangible assets; (iii) compliance-related professional fees; (iv) compliance-related compensation and other expenses; (v) spin-off professional fees; (vi) Italian VAT recovery recorded within operating expense; (vii) impairment of goodwill; (viii) impairment of property and equipment; (ix) certain litigation settlements and related costs; (x) restructuring expenses; and (xi) certain other gains and expenses. Compliance-related professional fees and compliance-related compensation and other expenses relate to fees and expenses recorded in connection with CTI’s and the Company's efforts to (a) complete certain financial statements and audits of such financial statements and (b) remediate material weaknesses in internal control over financial reporting.
	The tables below present information about total revenue, total costs and expenses, income (loss) from operations, segment performance, interest expense, and depreciation and amortization for the fiscal years ended January 31, 2014, 2013 and 2012:

The Company does not maintain balance sheets for the BSS and Digital Services operating segments and therefore is unable to present total assets for BSS, Digital Services and Comverse Other.
Revenue by major geographical region is based upon the geographic location of the customers who purchase the Company's products and services. The geographical locations of distributors, resellers and systems integrators who purchase products and utilize the Company's services may be different from the geographical locations of end customers. Revenue by geographic region and revenue by geographic region as a percentage of total revenue was as follows:

Leases	'
	LEASES
	The Company leases office and warehouse space, as well as certain equipment and vehicles, under non-cancelable operating leases. Gross rent expense was $19.6 million, $18.9 million and $21.6 million in the fiscal years ended January 31, 2014, 2013 and 2012, respectively. Sublease income was $2.1 million, $1.9 million and $2.0 million, in the fiscal years ended January 31, 2014, 2013 and 2012 respectively.
	The majority of the Company's leases include options that allow it to renew or extend the lease term beyond the initial lease period, subject to terms and conditions agreed upon at the inception of the lease. Such terms and conditions include rental rates agreed upon at the inception of the lease that could represent below-or above-market rental rates later in the life of the lease, depending upon market conditions at the time of such renewal or extension.
	The Company has entered into various sublease agreements to lease excess space. As of January 31, 2014, the minimum annual rent obligations (excluding taxes, maintenance and other pass-throughs), sublease income to be received under non-cancelable subleases, and minimum net rentals of the Company are as follows for the fiscal years ending January 31:

	In May 2012, the Company entered into an agreement for the lease of a facility in Ra'anana, Israel that is intended to replace its existing office space in Tel Aviv, Israel. The lease includes an option to terminate up to 30% of the Company's leased space in the building subject to a penalty. During the fiscal year ended January 31, 2014, the Company exercised this option and returned 27% of the leased space and recorded a liability for the termination penalty of $1.7 million during the fiscal year ended January 31, 2014. The term of the lease is for 10 years, expected to commence in October 2014. In addition, the Company has the right to extend the term of the lease by up to 5 years. The annual base rent under the agreement after partial return of office space, for approximately 218,912 square feet is expected to be $4.5 million. The Company expects that this facility will be used by BSS and Digital Services and the other operations included in All Other.
	In connection with the 2012 restructuring initiative, certain office space, including offices in New York, New York and a partial return of offices in Ra'anana, Israel, have been vacated or consolidated upon expiration of leases.

	COMMITMENTS AND CONTINGENCIES
	Indemnifications
	In the normal course of business, the Company provides indemnifications of varying scopes to customers against claims of intellectual property infringement made by third parties arising from the use of the Company's products. The Company evaluates its indemnifications for potential losses and in its evaluation considers such factors as the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss. Generally, the Company has not encountered significant expenses as a result of such indemnification provisions.
	To the extent permitted under state laws or other applicable laws, the Company has agreements in which it agreed to indemnify its directors and officers for certain events or occurrences while the director or officer is, or was, serving at the Company's request in such capacity. The indemnification period covers all pertinent events and occurrences during the Company's director's or officer's lifetime. The maximum potential amount of future payments that the Company could be required to make under these indemnification agreements is unlimited; however, the Company has certain director and officer insurance coverage that limits the Company's exposure and enables the Company to recover a portion of any future amounts paid. The Company is not able to estimate the fair value of these indemnification agreements in excess of applicable insurance coverage, if any.
	In addition, under the Share Distribution Agreements the Company entered into in connection with the Share Distribution, the Company has agreed to indemnify CTI and its affiliates (including Verint following the Verint Merger) against certain losses that may arise as a result of the Verint Merger and the Share Distribution (see Note 3, Expense Allocations and Share Distribution Agreements). On February 4, 2013, in connection with the closing of the Verint Merger Agreement, CTI placed $25.0 million in escrow to support indemnification claims to the extent made against the Company by Verint and any cash balance remaining in such escrow fund 18 months after the closing of the Verint Merger, less any claims made on or prior to such date, will be released to the Company. Although no indemnification claims have been filed and the Escrow Release Date is within 12 months of January 31, 2014, the Company continues to classify the restricted cash balance as "Long-term restricted cash" in the Consolidated Balance Sheets until it can be determined if any future claims would restrict the release of such escrow funds.
	As a result of the Verint Merger, Verint assumed certain rights and liabilities of CTI, including any liability of CTI arising out of the actions discussed below. Under the terms of the Distribution Agreement between CTI and us relating to the Share Distribution, Verint, as successor to CTI, is entitled to indemnification from us for any losses it suffers in its capacity as successor-in-interest to CTI in connection with these actions. As of the closing of the Verint Merger, the Company recognized the estimated fair value of the potential indemnification liability (see Note 1, Organization, Business and Summary of Significant Accounting Policies).
	Israeli Optionholder Class Action
	CTI and certain of its former subsidiaries, including Comverse Ltd. (a subsidiary of the Company), were named as defendants in four potential class action litigations in the State of Israel involving claims to recover damages incurred as a result of purported negligence or breach of contract due to previously-settled allegations regarding illegal backdating of CTI options that allegedly prevented certain current or former employees from exercising certain stock options. The Company intends to vigorously defend these actions.
	Two cases were filed in the Tel Aviv District Court against CTI on March 26, 2009, by plaintiffs Katriel (a former Comverse Ltd. employee) and Deutsch (a former Verint Systems Ltd. employee). The Katriel case (Case Number 1334/09) and the Deutsch case (Case Number 1335/09) both seek to approve class actions to recover damages that are claimed to have been incurred as a result of CTI’s negligence in reporting and filing its financial statements, which allegedly prevented the exercise of certain stock options by certain employees and former employees. By stipulation of the parties, on September 30, 2009, the court ordered that these cases, including all claims against CTI in Israel and the motion to approve the class action, be stayed until resolution of the actions pending in the United States regarding stock option accounting, without prejudice to the parties’ ability to investigate and assert the unique facts, claims and defenses in these cases. On May 7, 2012, the court lifted the stay, and the plaintiffs have filed an amended complaint and motion to certify a class of plaintiffs in a single consolidated class action. The defendants responded to this amended complaint on November 11, 2012, and the plaintiffs filed a further reply on December 20, 2012. A pre-trial hearing for the case was held on December 25, 2012, during which all parties agreed to attempt to settle the dispute through mediation. The mediation process is currently ongoing.
	Separately, on July 13, 2012, plaintiffs filed a motion seeking an order that CTI hold back $150 million in assets as a reserve to satisfy any potential damage awards that may be awarded in this case, but did not seek to enjoin the Share Distribution. The Company does not believe that the motion has merit. On July 25, 2012, the court indicated that it will not rule on the motion until after it rules on plaintiffs’ motion to certify a class of plaintiffs. On August 16, 2012, plaintiffs filed a motion for leave to appeal the court’s order to the Israeli Supreme Court and on November 11, 2012, CTI responded to plaintiff's motion. The parties are awaiting a decision.
	Two cases were also filed in the Tel Aviv Labor Court by plaintiffs Katriel and Deutsch, and both sought to approve class actions to recover damages that are claimed to have been incurred as a result of breached employment contracts, which allegedly prevented the exercise by certain employees and former employees of certain CTI and Verint stock options, respectively. The Katriel litigation (Case Number 3444/09) was filed on March 16, 2009, against Comverse Ltd., and the Deutsch litigation (Case Number 4186/09) was filed on March 26, 2009, against Verint Systems Ltd. The Tel Aviv Labor Court has ruled that it lacks jurisdiction, and both cases have been transferred to the Tel Aviv District Court. These cases have been consolidated with the Tel Aviv District Court cases discussed above. The Company did not accrue for these matters as the potential loss is currently not probable or estimable.
	An additional case has been filed by an individual plaintiff similarly seeking to recover damages up to an aggregate of $3.3 million allegedly incurred as a result of the inability to exercise certain stock options. The case generally alleges the same causes of actions alleged in the potential class action discussed above.
	On February 4, 2013, Verint and CTI completed the Verint Merger. As a result of the Verint Merger, Verint assumed certain rights and liabilities of CTI, including any liability of CTI arising out of the actions discussed above. However, under the terms of the Distribution Agreement between CTI and the Company relating to the Share Distribution, Verint, as successor to CTI, is entitled to indemnification from the Company for any losses it suffers in its capacity as successor-in-interest to CTI in connection with these actions.
	Guarantees
	The Company provides certain customers in the ordinary course of business with financial performance guarantees, which in certain cases are backed by standby letters of credit or surety bonds, the majority of which are cash collateralized and accounted for as restricted cash and bank time deposits. The Company is only liable for the amounts of those guarantees in the event of its nonperformance, which would permit the customer to exercise the guarantee. As of January 31, 2014 and 2013, the Company believes that it was in compliance with its performance obligations under all contracts for which there is a financial performance guarantee, and that any liabilities arising in connection with these guarantees will not have a material adverse effect on the Company’s consolidated and combined results of operations, financial position or cash flows. The Company also obtained bank guarantees primarily to provide customer assurance relating to the performance of certain obligations required by customer agreements for the guarantee of certain payment obligations. These guarantees, which aggregated $33.4 million and $31.1 million as of January 31, 2014 and 2013, respectively, are generally scheduled to be released upon the Company’s performance of specified contract milestones, a majority of which are scheduled to be completed at various dates through December 31, 2015.
	Unconditional Purchase Obligations
	In the ordinary course of business, the Company enters into certain unconditional purchase obligations, which are agreements to purchase goods or services that are enforceable, legally binding and specify all significant terms, including fixed or minimum quantities to be purchased, fixed, minimum or variable price provisions, and the approximate timing of the transaction. Purchase obligations exclude agreements that are cancelable without penalty. The Company had unconditional purchase obligations of approximately $16.2 million as of January 31, 2014. Of these obligations, $11.5 million are due in the next twelve months and $4.7 million are due in one to three years.
	Litigation Overview
	Except as disclosed below, the Company does not believe that it is currently party to any other claims, assessments or pending legal action that could reasonably be expected to have a material adverse effect on its business, financial condition or results of operations.
	Legal Proceedings
	From time to time, the Company and its subsidiaries are subject to claims in legal proceedings arising in the normal course of business. The Company does not believe that it or its subsidiaries are currently party to any pending legal action not described herein or disclosed in the consolidated and combined financial statements that could reasonably be expected to have a material adverse effect on its business, financial condition or results of operations.
	Brazil Tax and Labor Contingencies
	The Company's operations in Brazil are involved in various litigation matters and have received or been the subject of numerous governmental assessments related to indirect and other taxes, as well as disputes associated with former Company employees. The tax matters, which comprise a significant portion of the contingencies, principally relate to claims for taxes on the transfers of inventory, municipal service taxes on rentals and gross revenue taxes. The Company is disputing these tax matters and intends to vigorously defend its positions. The labor matters principally relate to claims made by former Company employees for pay wages, social security and other related labor benefits, as well as related tax obligations. As of January 31, 2014, the total amounts related to the reserved portion of the tax and labor contingencies was $0.1 million and the unreserved portion of the tax and labor contingencies totaled approximately $8.7 million. With respect to the unreserved balance, these have been assessed by management as being either remote or possible as to the likelihood of ultimately resulting in a loss to the Company. Local laws and regulations often require that the Company make deposits or post other security in connection with such proceedings. As of January 31, 2014, the Company had $6.8 million of deposits with the government in Brazil for claims that the Company is disputing which provides security with respect to these matters. Generally, any deposits would be refundable to the extent the matters are resolved in the Company's favor. Management routinely assesses these matters as to probability of ultimately incurring a liability against the Company's Brazilian operations and the Company records its best estimate of the ultimate loss in situations where management assesses the likelihood of an ultimate loss as probable.
	France Labor Contingency
	A former employee based in France has filed a notice of appeal in the appellate court, seeking to overturn a decision of the Labor Court rejecting his claim to requalify his resignation as a constructive dismissal and for damages in the Labor Court of approximately $2.8 million. The Company is disputing this appeal and intends to vigorously defend it. The Company has not accrued for this matter as the potential loss is not currently probable.
	Italy VAT
	The Company applied for Italian VAT refunds for the periods 2004 to 2010. However, collectability was deemed uncertain, as a result of the Italian financial crisis and other matters. On April 30, 2013, the Company received a refund approximating $10.9 million, which was recognized as a reduction of service costs in the consolidated statement of operations for the fiscal year ended January 31, 2014.

Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
Basis of Presentation	'
	Basis of Presentation
	The consolidated and combined financial statements included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).
	The Company’s combined financial statements for the periods prior to the Share Distribution have been derived from the consolidated financial statements and accounting records of CTI, using the historical results of operations, and historical basis of assets and liabilities of the Company’s businesses, which operated under common control of CTI. The Company’s combined financial statements combine, on the basis of common control, the results of operations and financial position of the Company and its subsidiaries with Starhome (66.5% owned by CTI as of January 31, 2012) and Exalink prior to CTI contributing Starhome and Exalink to the Company on September 19, 2012 and October 31, 2012, respectively. Management believes the assumptions and methodologies underlying the allocation of general, corporate expenses from CTI are reasonable (see Note 3, Expense Allocations and Share Distribution Agreements). However, such expenses may not be indicative of the actual level of expense that would have been incurred by the Company if it had operated as an independent, publicly-traded company. As such, the combined financial statements for periods prior to the Share Distribution included herein may not necessarily reflect what its results of operations, financial position, comprehensive income (loss) or cash flows would have been had the Company been an independent company during the periods presented. Subsequent to the Share Distribution, the financial statements are consolidated.
	Prior to the Share Distribution, transactions between the Company and CTI and CTI’s other subsidiaries were identified in the consolidated and combined financial statements as transactions between related parties (see Note 22, Related Party Transactions).
	For the purposes of the consolidated and combined statements of cash flows, prior to the Share Distribution, the Company reflected changes in unpaid balances with CTI as a financing activity.
	Intercompany accounts and transactions within the Company have been eliminated.
Segment Reporting	'
	Segment Reporting
	The Company determines its reportable segments in accordance with the Financial Accounting Standards Board's (the “FASB”) guidance relating to disclosures about segments of an enterprise and related information. The Company's Chief Executive Officer is its chief operating decision maker (the “CODM”). The CODM uses segment performance as its primary basis for assessing the financial results of the operating segments and for the allocation of resources (see Note 20, Business Segment Information, for additional discussion, including the definition of segment performance).
	The Company's operating and reportable segments are as follows:
	•	BSS, which conducts the Company's converged, prepaid and postpaid billing and active customer management systems business along with its policy solutions products and includes groups engaged in product management, delivery, support, professional services, research and development and product sales support; and
	•	Digital Services, which conducts the Company's digital services business and includes groups engaged in product management, delivery, support, professional services, research and development and product sales support.
	The Company does not maintain separate balance sheets for the BSS and Digital Services segments.
	The results of operations of the Company's global corporate functions, that provide common support to its segments, are included in the column captioned “All Other” as part of the Company's business segment presentation. All Other includes sales, marketing, finance, legal, and management as they provide services to both the BSS and Digital Services segments. In addition, there are certain delivery, support, and research and development groups that provide common support to the BSS and Digital Services segments, and therefore the costs of these common groups are included in All Other.
	Starhome's results of operations are included in discontinued operations and therefore not presented in segment information.
	Historically, Mobile Internet (“Comverse MI”), which was renamed Policy and is responsible for the Company's mobile Internet and policy products, and Netcentrex, an IP-based solution that provides carrier-hosted enterprise and consumer IP services, were included in All Other. Effective in the three months ended January 31, 2014 ("fourth quarter of fiscal 2013"), Comverse MI and Netcentrex have been combined with the Comverse BSS and Comverse Value Added Services (“VAS”) segments, respectively, to form the “BSS” and “Digital Services” segments. The change in segment reporting aligns with information reviewed by the Company's CODM, a change in management structure and the convergence of operations to take advantage of potential synergies. Accordingly, the results presented under segment reporting reflect the change in segment reporting for all periods presented to conform to the current period segment reporting structure. The change in segment reporting does not affect the Company’s previously reported consolidated and combined financial statements.
Use Of Estimates	'
	Use of Estimates
	The preparation of the consolidated and combined financial statements and the accompanying notes in conformity with U.S. GAAP requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses.
	The most significant estimates among others include:
	•	Estimates relating to the recognition of revenue, including the determination of vendor specific objective evidence (“VSOE”) of fair value and the determination of best estimate of selling price for multiple element arrangements;
	•	Fair value of stock-based compensation;
	•	Fair value of reporting units for the purpose of goodwill impairment testing;
	•	Realization of deferred tax assets;
	•	The identification and measurement of uncertain tax positions;
	•	Contingencies and litigation;
	•	Total estimates to complete on percentage-of-completion (“POC”) projects;
	•	Valuation of inventory;
	•	Israel employees severance pay;
	•	Probability assessment of performance based stock units vesting;
	•	Allowance for doubtful accounts;
	•	Valuation of other intangible assets; and
	•	Allocation of expenses by CTI to the Company.
	The Company’s actual results may differ from its estimates.
Foreign Currency and Foreign Currency Translation and Transactions	'
	Functional Currency and Foreign Currency Translation and Transactions
	The determination of the functional currency for the Company's foreign subsidiaries is made based on appropriate economic factors, including the currency in which the subsidiary sells its products, the sales market in which the subsidiary operates and the currency in which the subsidiary's financing is denominated. For foreign subsidiaries whose functional currency is not the U.S. dollar, assets and liabilities are translated using current exchange rates at the balance sheet date, and income and expense accounts using average exchange rates for the period, except revenue previously deferred which is translated using historical rates. The resulting foreign currency translation adjustments are reported as a separate component of “Other comprehensive income (loss), net of tax” in the consolidated and combined statements of comprehensive income (loss). For foreign subsidiaries whose functional currency is not the local currency, remeasurement gains and losses are recorded during each period in “Other expense, net” in the consolidated and combined statements of operations.
	Unrealized and realized foreign currency transaction gains and losses on transactions denominated in currencies other than the functional currency of the entity are included in the consolidated and combined statements of operations in “Other expense, net” for the period in which the exchange rates changed.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	Cash primarily consists of cash on hand and bank deposits. Cash equivalents primarily consist of interest-bearing money market accounts, commercial paper, agency notes and other highly liquid investments with an original maturity of three months or less when purchased. The Company maintains cash and cash equivalents in U.S. dollars and in foreign currencies, which are subject to risks related to foreign currency exchange rate fluctuations.
Restricted Cash and Bank Time Deposits	'
	Restricted Cash and Bank Time Deposits
	Restricted cash and bank time deposits include compensating cash balances related to existing lines of credit and deposits that are pledged as collateral or restricted for use to settle specified performance guarantees to customers and vendors, letters of credit, indemnification claims, foreign currency transactions in the ordinary course of business and pending tax judgments. Cash expected to be restricted for more than one year from the balance sheet date is classified as long-term restricted cash. Restricted bank time deposits generally consist of certificates of deposit with original maturities of twelve months or less.
Accounts Receivable, Net and Allowance for Doubtful Accounts	'
	Accounts Receivable, Net
	The application of revenue recognition guidance often results in circumstances for which the Company is unable to recognize revenue relating to sales transactions that have been billed. In these circumstances, the Company does not recognize the deferred revenue or the related accounts receivable and no amounts are recognized in the consolidated balance sheets for such transactions with the exception of certain arrangements recognized in accordance with the FASB's guidance relating to accounting for performance of construction-type and certain production-type contracts. Only to the extent that the Company has recognized revenue and not received cash for such transactions are amounts included in “Accounts receivable, net.” Also, only to the extent that the Company has received cash for such transactions is the amount included in “Deferred revenue” in the consolidated balance sheets.
	Accounts receivable, net includes $13.9 million and $15.5 million of a long-term contract as of January 31, 2014 and 2013, respectively, which has associated corresponding deferred revenue classified in current liabilities of $46.5 million and $44.6 million as of January 31, 2014 and 2013, respectively.
	Allowance for Doubtful Accounts
	The Company estimates the collectability of its accounts receivable balances for each accounting period and adjusts its allowance for doubtful accounts accordingly. The Company exercises judgment in assessing the collectability of accounts receivable, including consideration of current economic conditions, the creditworthiness of customers, their collection history and the related aging of past due receivables balances. The Company evaluates specific accounts when it becomes aware that a customer may be experiencing a deterioration of its financial condition due to lower credit ratings, bankruptcy or other factors that may affect such customer's ability to meet its payment obligations. The Company expenses uncollectible trade receivables when all collection efforts have been exhausted and the Company believes the amount will not be collected.
Investments	'
	Investments
	The Company accounts for investments in accordance with the FASB's guidance relating to accounting for certain investments in debt and equity securities. Purchases are recorded on the settlement date.
	Interest on short-term investments is recognized in the consolidated and combined statements of operations when earned. Realized gains and losses on available-for-sale securities are recognized when securities are sold and are calculated using the specific identification method, and are recorded in “Other expense, net” in the consolidated and combined statements of operations. Unrealized gains and losses, net of taxes, are recorded as a component of “Accumulated other comprehensive income” in the consolidated and combined statements of equity.
	Generally, investments with original maturities of greater than three months and remaining maturities of less than one year are classified as short-term investments.
	The Company reviews its investments for indications of impairment in value on a quarterly basis. The Company considers an investment to be impaired when the fair value is less than the carrying value (or amortized cost). The Company evaluates each impaired investment individually to determine whether such investment is other-than-temporarily impaired.
Inventories	'
	Inventories
	Inventories are stated at the lower of cost or market. Cost is determined by the first-in, first-out or weighted-average methods which approximates the first-in, first-out method. The Company reduces the carrying value of inventory when it holds excess or obsolete inventories determined through an evaluation of both historical usage and expected future demand. Part of the raw materials comprises software licenses, which are capitalized into inventory upon purchase from a vendor when the license will be used by the Company as part of its deliverables to its customers. Such expenses are included as a component of “Product costs” in the consolidated and combined statements of operations.
	The Company evaluates slow moving or obsolete inventory for impairment. Raw material hardware is evaluated based upon utilization and projected usage. Raw material software is written-off upon determination that licenses will no longer be used in products nor can be converted to use within the organization or with other licenses/products.
Property and Equipment	'
	Property and Equipment
	Property and equipment are carried at cost less accumulated depreciation and amortization. The Company depreciates and amortizes its property and equipment on a straight-line basis. Leasehold improvements are capitalized and amortized over the shorter of their estimated useful lives or the related lease term. The cost of maintenance and repairs is expensed as incurred. The estimated useful lives of property and equipment are as follows:
		Useful Life in Years
		Shortest		Longest
	Lab equipment	5		5
	Technology equipment	3		7
	Software	1		5
	Leasehold improvements	3		15
	Production equipment	1		6
	Furnishings	3		10
Business Combinations	'
	Business Combinations
	The Company allocates the fair value of consideration transferred in a business combination to the estimated fair value at the acquisition date of the tangible and intangible assets acquired, the liabilities assumed and any non-controlling interest. Acquisition costs are expensed as incurred. Any residual consideration is recorded as goodwill. The fair value of consideration includes cash, equity securities, other assets and contingent consideration. The Company remeasures the fair value of contingent consideration at each reporting period and any change in the fair value from either the passage of time or events occurring after the acquisition date, is recorded in earnings. The Company's determination of the fair values of assets acquired and liabilities assumed requires the Company to make significant estimates, primarily with respect to intangible assets. These estimates can include, but are not limited to, cash flow projections for the acquired business, and the appropriate weighted-average cost of capital. The results of operations of the acquired business are included in the Company's consolidated and combined results of operations from the date of the acquisition. The Company had no business combinations in any period presented.
Noncontrolling interest	'
	Noncontrolling Interest
	Noncontrolling interest represents the minority shareholders' interest in Starhome, the Company's former majority-owned subsidiary (see Note 16, Discontinued Operations). The Company recognizes income attributable to the noncontrolling interest as a separate component of net income (loss) in the Company's consolidated and combined statements of operations.
	Prior to the Starhome Disposition, the noncontrolling interest of Starhome was 33.5%.
Goodwill	'
	Goodwill
	Goodwill represents the excess of the fair value of consideration transferred in a business combination over the fair value of tangible and intangible assets acquired net of the fair value of liabilities assumed and the fair value of any noncontrolling interest in the acquiree. The Company has no indefinite-lived intangible assets other than goodwill. The carrying amount of goodwill is reviewed annually for impairment on November 1 and whenever events or changes in circumstances indicate that the carrying value may not be recoverable.
	The Company applies the FASB's guidance when testing goodwill for impairment which permits the Company to make a qualitative assessment of whether goodwill is impaired, or opt to bypass the qualitative assessment, and proceed directly to performing the first step of the two-step impairment test. If the Company performs a qualitative assessment and concludes it is more-likely-than-not that the fair value of a reporting unit exceeds its carrying value, goodwill is not considered impaired and the two-step impairment test is unnecessary. However, if the Company concludes otherwise, it is then required to perform the first step of the two-step impairment test.
	The Company has the unconditional option to bypass the qualitative assessment for any reporting unit and proceed directly to performing the first step of the goodwill impairment test. The Company may resume performing the qualitative assessment in any subsequent period.
	For reporting units where the Company decides to perform a qualitative assessment, the Company's management assesses and makes judgments regarding a variety of factors which potentially impact the fair value of a reporting unit, including general economic conditions, industry and market-specific conditions, customer behavior, cost factors, financial performance and trends, strategies and business plans, capital requirements, management and personnel issues, and stock price, among others. Management then considers the totality of these and other factors, placing more weight on the events and circumstances that are judged to most affect a reporting unit's fair value or the carrying amount of its net assets, to reach a qualitative conclusion regarding whether it is more-likely-than-not that the fair value of a reporting unit exceeds its carrying amount.
	For reporting units where the Company performs the two-step goodwill impairment test, the first step requires the Company to compare the fair value of each reporting unit to the carrying value of its net assets. The Company considers both an income-based approach using projected discounted cash flows and a market-based approach using multiples of comparable companies to determine the fair value of its reporting units. The Company's estimate of fair value of each reporting unit is based on a number of subjective factors, including: (i) the appropriate weighting of valuation approaches (income-based approach and market-based approach), (ii) estimates of the future revenue and cash flows, (iii) discount rate for estimated cash flows, (iv) selection of peer group companies for the market-based approach, (v) required levels of working capital, (vi) assumed terminal value, (vii) the time horizon of cash flow forecasts; and (viii) control premium.
	If the fair value of the reporting unit exceeds its carrying value, goodwill is not considered impaired and no further evaluation is necessary. If the carrying value of the reporting unit is greater than the estimated fair value of the reporting unit, there is an indication that impairment may exist and the second step is required. In the second step, the implied fair value of goodwill is calculated as the excess of the fair value of a reporting unit over the fair value assigned to its assets and liabilities. If the implied fair value of goodwill is less than the carrying value of the reporting unit's goodwill, the difference is recognized as an impairment charge.
	The Company recorded an impairment charge of approximately $5.6 million for the fiscal year ended January 31, 2013. The Company did not record any impairment of goodwill for the fiscal years ended January 31, 2014 and 2012.
	The Company's forecasts and estimates are based on assumptions that are consistent with the plans and estimates used to manage the business. Changes in these estimates could change the conclusion regarding an impairment of goodwill.
Impairment of Long-Lived and Intangible Assets	'
	Impairment of Long-Lived and Intangible Assets
	The Company reviews the recoverability of its long-lived assets, such as property and equipment and intangible assets with finite lives, whenever events or changes in circumstances occur that indicate that the carrying value of the asset may not be recoverable. Any impairment of these assets must be considered prior to the Company's impairment review of goodwill. The assessment of impairment is based on the Company's ability to recover the carrying value of the asset by analyzing the expected future undiscounted pre-tax cash flows specific to the asset or asset group.
	Circumstances which could trigger a review include, but are not limited to, significant decreases in the market price of the asset, significant adverse changes in the business climate or legal factors, accumulation of costs significantly in excess of the amount expected for the acquisition of a long-lived asset, current period negative cash flow or operating losses combined with a history of losses or a forecast of continuing losses associated with the use of the asset.
	The Company assesses the recoverability of the carrying value of long-lived assets at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. If undiscounted cash flows are less than the carrying value of such asset or asset group, an impairment loss is measured based on the difference between estimated fair value and carrying value. An impairment loss on intangible assets is reported as “Impairment of intangible assets” in the consolidated and combined statements of operations. Assets to be disposed of are written-down to the greater of fair value or salvage value. Estimated fair values are based on assumptions regarding the amount and timing of estimated future cash flows and appropriate discount rates to reflect varying degrees of perceived risk.
Fair Value Measurements	'
	Fair Value Measurements
	Under the FASB's guidance, fair value is defined as the price that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., “the exit price”).
	In determining fair value, the Company uses various valuation approaches, including quoted market prices and discounted cash flows. The FASB's guidance also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from independent sources. Unobservable inputs are inputs that reflect a company's judgment concerning the assumptions that market participants would use in pricing the asset or liability developed based on the best information available under the circumstances. The fair value hierarchy is broken down into three levels based on the reliability of inputs as follows:
	Level 1-Valuations based on quoted prices in active markets for identical instruments that the Company is able to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these instruments does not entail a significant degree of judgment.
	Level 2-Valuations based on quoted prices in active markets for instruments that are similar, or quoted prices in markets that are not active for identical or similar instruments, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.
	Level 3-Valuations based on inputs that are unobservable and significant to the overall fair value measurement.
	To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an asset or liability is classified in its entirety based on the lowest level of input that is significant to the measurement of fair value.
	Fair value is a market-based measure considered from the perspective of a market participant who holds the asset or owes the liability rather than an entity-specific measure. Therefore, even when market assumptions are not readily available, the Company's own assumptions are set to reflect those that market participants would use in pricing the asset or liability at the measurement date. The Company uses prices and inputs that are current as of the measurement date, including during periods of market dislocation.
	The FASB's guidance requires that the valuation techniques used are consistent with at least one of the three possible approaches: the market approach, income approach, and/or cost approach. The Company's Level 2 valuations use the market approach and are based on significant other observable inputs such as quoted prices for financial instruments not traded on a daily basis.
	The FASB's guidance relating to the fair value option for financial assets and financial liabilities permits an instrument-by-instrument irrevocable election to account for selected financial instruments at fair value. The Company elected not to apply the fair value option to any eligible financial assets or financial liabilities.
	The Company also elected not to apply the fair value option for non-financial assets and non-financial liabilities.
Derivative Instruments and Hedge Accounting	'
	Derivative Instruments and Hedge Accounting
	As part of the Company's risk management strategy, it uses derivative financial instruments, primarily forward contracts, to hedge against certain foreign currency exposures. The Company recognizes all derivatives as either assets or liabilities in the consolidated balance sheets at their fair value on a trade date basis. Short-term derivatives in a gain position are reported in “Prepaid expenses and other current assets” in the consolidated balance sheets and derivatives in a loss position are recorded in “Other current liabilities” in the consolidated balance sheets.
	In order to qualify for hedge accounting, the Company formally documents at the inception of each hedging relationship the hedging instrument, the hedged item, the risk management objective and strategy for undertaking each hedging relationship, and the method used to assess hedge effectiveness, which includes the Company's assessment of the creditworthiness of each party and their ability to comply with the contractual terms of the hedging derivative.
	When derivative financial instruments qualify for cash flow hedge accounting, the Company records the effective portion of changes in fair value as part of other comprehensive income (loss) in the consolidated and combined statements of equity. When the hedged item is recognized in the consolidated and combined statements of operations, the related derivative gain or loss is reclassified from “Accumulated other comprehensive income (loss)” in the consolidated and combined statements of equity to the consolidated and combined statements of operations within the line item in which the hedged item is recorded. The cash flows from a derivative financial instrument qualifying for cash flow hedge accounting are classified in the consolidated and combined statements of cash flows in the same category as the cash flows from the hedged item.
	If a derivative financial instrument does not qualify for hedge accounting, the Company records the changes in fair value of derivative instruments in “Other expense, net” in the consolidated and combined statements of operations.
	The Company does not purchase, hold or sell derivative financial instruments for trading and speculative purposes.
Concentration of Credit Risk	'
	Concentration of Credit Risk
	Financial instruments, which potentially expose the Company to credit risk, consist primarily of investments, derivatives and accounts receivable. From time to time, the Company invests excess cash in high credit-quality financial institutions and invests primarily in money market funds placed with major banks and financial institutions and corporate commercial paper. The Company believes that the financial institutions that hold its cash and liquid investments are financially sound and accordingly minimal credit risk exists with respect to these balances.
	A significant portion of accounts receivable are with communication service providers. However, the concentration of credit risk is diversified due to the large number of commercial and government entities comprising the Company's customer base and their dispersion across different industries and geographic regions. The Company manages credit risk on trade accounts receivable by performing ongoing credit evaluations of its customers' financial condition and limiting the extension of credit when deemed necessary.
	For the fiscal years ended January 31, 2014 and 2013, one customer represented approximately 18% and 14%, respectively, of total revenue, in which revenue is attributable to the Digital Services segment. No customer accounted for 10% or more of total revenue for the fiscal year ended January 31, 2012.
	For the fiscal years ended January 31, 2014 and 2013, one customer accounted 16% and 13% of the combined accounts receivable as of January 31, 2014 and 2013, respectively. The revenues related to these receivables have been completely deferred in each of the periods presented. Additionally, another customer accounted for 13% of the combined accounts receivable as of January 31, 2013. The Company believes that no significant customer credit risk exists other than what is reserved.
	The Company depends on a limited number of suppliers and manufacturers for certain components and is exposed to the risk that these suppliers and manufacturers will not be able to fill its orders on a timely basis and at the specifications it requires.
Revenue Recognition	'
	Revenue Recognition
	The Company reports its revenue in two categories: (i) product revenue, including hardware and software products; and (ii) service revenue, including revenue from professional services, training services and post-contract customer support (“PCS”). Professional services primarily include installation, customization and consulting services.
	The Company's revenue is accounted for in accordance with the FASB's guidance relating to multiple element arrangements entered into or materially modified on or after February 1, 2011 that include hardware which functions together with software to provide the essential functionality of the product. Revenue recognition for software and (or) services arrangements are accounted under the FASB's new guidance applicable to multiple element arrangements. In applying the FASB's guidance, the Company exercises judgment and uses estimates in determining the revenue to be recognized in each accounting period.
	For arrangements that do not require significant customization of the underlying software, the Company recognizes revenue when it has persuasive evidence of an arrangement, the product has been shipped and the services have been provided to the customer, the sales price is fixed or determinable, collectability is probable, and all other pertinent criteria are met as required by the FASB's guidance.
	In certain instances, payment terms extend beyond the Company's customary practices. In these situations, if a customer does not have an adequate history of abiding by its contractual payment terms without concessions, the sales price is not considered fixed or determinable. As such, revenue recognition commences upon collection, provided all other revenue recognition criteria have been met.
	Under certain contractual arrangements, the Company is required to pay a penalty or liquidated damages if delivery of the Company's products and installation services are not completed by a certain date. In other arrangements, the Company has guaranteed product performance and warranty service response rates, which, if not met, can result in penalties. The Company assesses whether such penalties are akin to a warranty provision or contingent revenue. To the extent that the penalties are akin to a warranty provision, the Company accounts for such penalties or liquidated damages in accordance with the FASB's guidance relating to contingencies.
	Shipping and handling amounts billed to the Company's customers are included in product revenue and the related shipping and handling costs are included in product costs.
	The Company reports revenue net of any revenue-based taxes assessed by governmental authorities that are imposed on and concurrent with specific revenue producing transactions.
	The following are the specific revenue recognition policies for each major category of revenue.
	Multiple Element Arrangements
	Revenue arrangements may incorporate one or more elements in a single transaction or combination of related transactions. In September 2009, the FASB issued revenue recognition guidance applicable to multiple element arrangements, which applies to multiple element revenue arrangements that contain both software and hardware elements, focusing on determining which revenue arrangements are within the scope of the software revenue guidance; and addresses how to separate consideration related to each element in a multiple element arrangement, excluding software arrangements, and establishes a hierarchy for determining the selling price of an element. It also eliminates the residual method of allocation by requiring that arrangement consideration be allocated at the inception of the arrangement to all elements using the relative selling price method.
	Certain of the Company's multiple element arrangements include hardware that functions together with software to provide the essential functionality of the product. Therefore, such arrangements entered into or materially modified on or after February 1, 2011 are no longer accounted for in accordance with the FASB's software accounting guidance. Accordingly, the selling price used for each deliverable is based on VSOE of fair value, if available, third party evidence (“TPE”) of fair value if VSOE is not available, or the Company's best estimate of selling price (“BESP”) if neither VSOE nor TPE is available. In determining the units of accounting for these arrangements, the Company evaluates whether each deliverable has stand-alone value as defined in the FASB's guidance. Given that the hardware and software function together to provide the essential functionality of the product and each element is critical to the overall tangible product sold, neither the software nor the hardware have stand-alone value. Professional services performed prior to the product's acceptance do not have stand-alone value and are therefore combined with the related hardware and software as one non-software deliverable. After determining the fair value for each deliverable, the arrangement consideration is allocated using the relative selling price method. Revenue is recognized accordingly for each deliverable once the respective revenue recognition criteria are met for that deliverable.
	The Company has not yet established VSOE of fair value for any element other than PCS for a portion of its arrangements. Generally, the Company is not able to determine TPE because its offerings contain a significant level of differentiation such that the comparable pricing of substantially similar products or services cannot be obtained. When the Company is unable to establish fair value of its non-software deliverables using VSOE or TPE, it uses BESP in its allocation of arrangement consideration. The objective of BESP is to determine the price at which it would transact a sale if the product or service were sold on a stand-alone basis, which requires significant judgment. The Company determines BESP for a product or service by considering multiple factors, including, but not limited to, cost of products, gross margin objectives, pricing practices, geographies and customer classes. The Company exercises judgment and uses estimates in determining the revenue to be recognized in each accounting period.
	The majority of multiple element arrangements contain at least two of the following elements: (1) tangible product (hardware, software, and professional services performed prior to the product's acceptance), (2) PCS, (3) training, and (4) post acceptance services. The Company's tangible products are rarely sold separately. In addition, the Company's tangible products are complex, and contain a high degree of customizations such that the Company is unable to demonstrate pricing within a pricing range to establish BESP as very few contracts are comparable. Therefore, the Company has concluded that cost plus a target gross profit margin provides the best estimate of the selling price.
	PCS, training, and post acceptance services have various pricing practices based on several factors, including the geographical region of the customer, the size of the customer's installed base, the volume of services being sold and the type or class of service being performed. As noted above, the Company has VSOE of PCS for a portion of its arrangements. For PCS, the Company uses its minimum substantive VSOE thresholds by region plus a reasonable margin as the basis to estimate BESP of PCS for transactions that do not meet the VSOE criteria. For training and post-acceptance services, the Company performs an annual study of stand-alone training and post-acceptance sales to arrive at BESP. While the study does not result in VSOE, it is useful in determining the Company's BESP.
	With the exception of arrangements that require significant customization of the product to meet the particular requirements of the customer, which are accounted for using the percentage-of-completion method, the initial revenue recognition for each non-software product only deliverable is generally upon completion of the related professional services.
	For all multiple element arrangements without hardware, the Company allocates revenue to the delivered elements of the arrangement using the residual method, whereby revenue is allocated to the undelivered elements based on VSOE of fair value of the undelivered elements with the remaining arrangement fee allocated to the delivered elements and recognized as revenue assuming all other revenue recognition criteria are met. If the Company is unable to establish VSOE of fair value for the undelivered elements of the arrangement, revenue recognition is deferred for the entire arrangement until all elements of the arrangement are delivered. However, if the only undelivered element is PCS, the Company recognizes the arrangement fee ratably over the PCS period.
	PCS revenue is derived primarily from providing technical software support services, unspecified software updates and upgrades to customers on a when and if available basis. PCS revenue is recognized ratably over the term of the PCS period. When PCS is included within a multiple element arrangement and the arrangement is within the scope of the software revenue guidance, the Company primarily utilizes the substantive renewal rate to establish VSOE of fair value for PCS.
	The Company's policy for establishing VSOE of fair value for professional services and training is based upon an analysis of separate sales of services, which are then compared with the fees charged when the same elements are included in a multiple element arrangement. The Company has not yet established VSOE of fair value for any element other than PCS.
	When using the substantive renewal rate method, the Company may be unable to establish VSOE of fair value for PCS because the renewal rate is deemed to be non-substantive or there are no contractually-stated renewal rates. If the stated renewal rate is non-substantive, the entire arrangement fee is recognized ratably over the estimated economic life of the product (five to eight years) beginning upon delivery of all elements other than PCS. The Company believes that the estimated economic life of the product is the best estimate of how long the customer will renew PCS. If there is no contractually stated renewal rate, the entire arrangement fee is recognized ratably over the relevant contractual PCS term beginning upon delivery of all elements other than PCS.
	In certain multiple element arrangements, the Company is obligated to provide training services to customers related to the operation of the Company's software products. These training services are either provided to the customer on a “defined” basis (limited to a specified number of days or training classes) or on an “as-requested” basis (unlimited training over a contractual period).
	For multiple element arrangements containing as-requested training obligations that are within the scope of the software revenue guidance, the Company recognizes the total arrangement consideration ratably over the contractual period during which the Company is required to “stand ready” to perform such training, provided that all other criteria for revenue recognition have been met.
	For multiple element arrangements containing defined training obligations, the training services are typically provided to the customer prior to the completion of the installation services. For multiple element arrangements that are not within the scope of the software guidance, training is treated as a separate deliverable and recognized when delivered. For arrangements that are within the scope of the software revenue guidance, because revenue recognition does not commence until the completion of installation, the defined training obligations do not impact the timing of recognition of revenue. In certain circumstances in which training is provided after the end of the installation period, the Company commences revenue recognition upon the completion of training, provided that all other criteria for revenue recognition have been met.
	In its multiple element arrangements the Company may offer a discount on future purchases of products and services. A discount is considered an additional element of an arrangement if the discount is considered more than insignificant. A more-than-insignificant discount with respect to future purchases is a discount that is: (i) incremental to the range of discounts reflected in the pricing of the other elements of the arrangement, (ii) incremental to the range of discounts typically given in comparable transactions, and (iii) significant. Insignificant discounts and discounts that are not incremental do not affect revenue recognition. If the discount is considered more than insignificant, then a portion of the fee received is deferred and recognized as revenue as the future purchases are made by the customer or upon expiration of the period that the discount is available.
	Some of the Company's arrangements require significant customization of the product to meet the particular requirements of the customer. For these arrangements, revenue is typically recognized in accordance with the FASB's guidance for long-term construction type contracts using the POC method.
	The determination of whether services entail significant customization requires judgment and is primarily based on alterations to the features and functionality to the standard release, complex or unusual interfaces as well as the amount of hours necessary to complete the customization solution relative to the size of the contract. Revenue from these arrangements is recognized on the POC method based on the ratio of total hours incurred to date compared to estimated total hours to complete the contract.
	Management is required to make judgments to estimate the total estimated costs and progress to completion. Changes to such estimates can impact the timing of the revenue recognition period to period. The Company uses historical experience, project plans, and an assessment of the risks and uncertainties inherent in the arrangement to establish these estimates. Uncertainties in these arrangements include implementation delays or performance issues that may or may not be within the Company's control. If some level of profitability is assured, but the related revenue and costs cannot be reasonably estimated, then revenue is recognized to the extent of costs incurred until such time that the project's profitability can be estimated or the services have been completed. If the Company determines that based on its estimates its costs exceed the sales price, the entire amount of the estimated loss is accrued in the period that such losses become known.
	The change in profit estimate of one BSS contract accounted for under the percentage of completion method negatively impacted income from operations by $14.8 million during the fiscal year ended January 31, 2013. Although there were no individually large profit estimate adjustments during fiscal year 2013, the fourth fiscal quarter ended January 31, 2014 was impacted by the recording of loss contract reserves of $7.1 million for three contracts accounted for under the Percentage of Completion method.
	Revenue derived from sales to distributors, resellers, and value-added resellers are recognized when the resellers in turn sell the software product to their customers and installation of the software product has occurred, provided all other revenue recognition criteria are met. This is commonly referred to as the sell-through method. The contractual arrangements between the reseller and end user, or between the reseller and the Company, generally obligate the Company to provide services to the end user that are subject to end user acceptance. Further, payment terms are generally subject to the reseller's receiving payment from the end user and the end user's acceptance of the product. Therefore, the Company defers recognition until there is a “sell-through” by the reseller to an actual end user customer and acceptance by the end user.
	In the consolidated and combined statements of operations, the Company classifies revenue as product revenue or service revenue. For multiple element arrangements that include both product and service elements, management evaluates various available indicators of fair value and applies its judgment to reasonably classify the arrangement fee between product revenue and service revenue. The amount of multiple element arrangement fees classified as product and service revenue based on management estimates of fair value when VSOE of fair value for all elements of an arrangement does not exist could differ from amounts classified as product and service revenue if VSOE of fair value for all elements existed. The allocation of multiple element arrangement fees between product revenue and service revenue, when VSOE of fair value for all elements does not exist, is for consolidated and combined financial statement presentation purposes only and does not affect the timing or amount of revenue recognized.
	In determining the amount of a multiple element arrangement fee that should be classified between product revenue and service revenue, the Company first allocates the arrangement fee to product revenue and PCS (PCS is classified as service revenue) based on management's estimate of fair value for those elements. The remainder of the arrangement fee, which is comprised of all other service elements, is allocated to service revenue. The estimate of fair value of the product element is based primarily on management's evaluation of direct costs and reasonable profit margins on those products. This was determined to be the most appropriate methodology as the Company has historically been product-oriented with respect to pricing policies which facilitates the evaluation of product costs and related margins in arriving at a reasonable estimate of the product element fair value. Management's estimate of reasonable profit margins requires significant judgment and consideration of various factors, such as the impact of the economic environment on margins, the complexity of projects, the stability of product profit margins and the nature of products. The estimate of fair value for PCS is based on management's evaluation of the weighted-average of PCS rates for arrangements for which VSOE of fair value of PCS exists.
	Post-Contract Customer Support Renewals
	The Company's multiple element arrangements typically provide for renewal of PCS terms upon expiration of the original term. The amounts of these PCS renewals are recognized as revenue ratably over the specified PCS renewal period.
	Professional Services Only Arrangements
	Based on the type and nature of its professional-services-only arrangements, the Company recognizes revenue using either the proportional performance method, ratable recognition, completed performance method or on a time and materials basis. For fixed-fee arrangements recognized based on the proportional performance method, the Company typically measures progress to completion based on the ratio of hours incurred to total estimated project hours, an input method. For fixed-fee arrangements recognized based on the completed performance method, the Company recognizes revenue once the services are completed and there are no other obligations of the Company. The Company recognizes revenue for time and materials arrangements as the services are performed based on contractually stipulated billing rates.
Product and Service Costs	'
	Product and Service Costs
	The Company's cost of revenue primarily consists of (i) material costs, (ii) compensation and related overhead expenses for personnel involved in the customization of its products, customer delivery and maintenance and professional services, (iii) contractor costs, (iv) royalties and license fees, (v) depreciation of equipment used in operations, and (vi) amortization of capitalized software costs and certain purchased intangible assets.
	When revenue is recognized over multiple periods in accordance with the Company's revenue recognition policies, the material cost, including hardware and third party software license fees are deferred and amortized over the same period that product revenue is recognized. These costs are recognized as “Deferred cost of revenue” on the consolidated balance sheets. However, the Company has made an accounting policy election whereby the cost for installation and other service costs are expensed as incurred, except for arrangements recognized in accordance with the FASB's guidance for long-term construction type contracts.
	For certain contracts where revenue is recognized in accordance with the FASB's guidance for long-term construction type contracts, revisions in estimates of costs are reflected in the accounting period in which the facts that require the revision become known. These costs include all direct material and labor costs and overhead related to contract performance.
Research and Development, Net and Software Costs	'
	Research and Development, Net
	Research and development, net expenses primarily consist of personnel-related costs involved in product development and third party development and programming costs. Research and development costs are expensed as incurred.
	A portion of the Company’s research and development operations are located in Israel, where certain of the Company’s subsidiaries derive benefits from participation in programs sponsored by the Government of Israel for the support of research and development activities in Israel. Certain of the Company’s research and development activities include projects partially funded by the Office of the Chief Scientist of the Ministry of Industry and Trade of the State of Israel (the “OCS”) under which the funding organization reimburses a portion of the Company’s research and development expenditures under approved project budgets. Although the Government of Israel does not own proprietary rights in the OCS-funded Products and there is no specific restriction by the OCS with regard to the export of the OCS-funded Products, under certain circumstances, there may be limitations on the ability to transfer technology, know-how and manufacturing of OCS-funded Products outside of Israel. Such limitations could result in the requirement to pay increased royalties or a redemption fee calculated according to the applicable regulations.
	The Company’s gross research and development expenses for the fiscal years ended January 31, 2014, 2013 and 2012 were $67.6 million, $77.0 million and $94.3 million, respectively. Amounts reimbursable by the OCS and others for the fiscal years ended January 31, 2014, 2013 and 2012, were $0.1 million, $0.5 million and $0.1 million, respectively, which were recorded as a reduction to gross research and development expenses within “Research and development, net” in the consolidated and combined statements of operations.
	Software Costs
	Costs of software developed for internal use are capitalized in accordance with the FASB's guidance during the application development stage and are then amortized over the estimated useful life of the software, which to date has been five years or less once the software is ready for its intended use. These costs are included in “Property and equipment, net” in the consolidated balance sheets.
Sales and Marketing	'
	Sales and Marketing
	Sales and marketing expenses include payroll, employee benefits, stock-based compensation, and other headcount-related expenses associated with sales and marketing personnel, and the costs of advertising, promotions and other programs. In addition, the Company's customer acquisition and origination costs, including sales and agent commissions are expensed when incurred, with the exception of certain sales referral fees that are capitalized and amortized ratably over the revenue recognition period. Advertising costs are expensed as incurred.
Stock-Based Compensation	'
	Stock-Based Compensation
	Stock-based compensation expense is measured at the grant date based on the fair value of the award derived using the Black-Scholes option-pricing model and the cost is recognized as expense ratably over the award's vesting period, which generally vest ratably over two or three years and expire ten years from the date of grant. The Black-Scholes model requires making certain assumptions used within the model, the most significant of which are the stock price volatility assumption over the term of the awards and the expected life of the option award based on the actual and projected employee stock option behaviors. Other assumptions include the risk-free rate of return and dividends during the expected term.
	The Company estimates expected forfeitures of stock-based awards at the grant date and recognizes compensation cost only for those awards expected to vest. Forfeiture rates are estimated based on historical experience of Comverse employees while employed by CTI prior to the Share Distribution. The forfeiture assumption is adjusted to the actual forfeitures that occur. Therefore, changes in the forfeiture assumptions may impact the amount and timing of the total amount of expense recognized over the vesting period. Estimated forfeitures are reassessed in subsequent periods and may change based on new facts and circumstances.
	The fair value of equity instruments issued to a nonemployee is measured by using the stock price and other measurement assumptions as of the date earlier of either: (i) a commitment for performance by the nonemployee has been reached; or (ii) the counterparty's performance is complete. Expenses related to nonemployee awards are generally recognized in the same period and in the same manner as the Company incurs the related liability for goods and services received.
	In connection with the Share Distribution, CTI's equity-based compensation awards held by the Company's employees were replaced with the Company's equity-based compensation awards on November 1, 2012. The replacement of CTI's equity-based compensation awards was considered a modification that resulted in a negligible increase in the fair value of the awards. The Company's combined statements of operations prior to the Share Distribution include expenses related to the Company's employee participation in the CTI plans.
APIC Pool and Income Taxes	'
	APIC Pool
	The long form method is used to determine the Company's pool of excess tax benefits available within additional paid-in capital. Excess tax benefits resulting from stock option exercises are recognized as additions to APIC in the period the benefit is realized. In the event of a shortfall (that is, the tax benefit realized is less than the amount previously recognized through periodic stock-based compensation expense recognition and related deferred tax accounting), the shortfall is charged against APIC to the extent of previous excess benefits, if any, including the hypothetical APIC pool, and then to tax expense.
	Income Taxes
	Income taxes are provided using the asset and liability method, such that income taxes (i.e., deferred tax assets, deferred tax liabilities, taxes currently payable/refunds receivable and tax expense/benefit) are recorded based on amounts refundable or payable in the current year and include the results of any difference between U.S. GAAP and tax reporting. Deferred income taxes reflect the tax effect of net operating losses, capital losses and general business credit carryforwards and the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial statement and income tax purposes, as determined under enacted tax laws and rates. Valuation allowances are established when management determines that it is more-likely-than-not that some portion or all of the deferred tax asset will not be realized. The financial effect of changes in tax laws or rates is accounted for in the period of enactment. The subsequent realization of net operating loss and general business credit carryforwards acquired in acquisitions accounted for using the acquisition method of accounting is recognized in the consolidated and combined statement of operations.
	The Company was included in the CTI consolidated federal and certain combined state income tax returns until completion of the Share Distribution. As such, the Company was not a separate taxable entity for U.S. federal and certain state income tax purposes until completion of the Share Distribution. In addition, the Company did not have a written tax sharing agreement with CTI. The Company's provisions for income taxes and related balance sheet accounts were presented as if the Company were a separate taxpayer (“separate return method”). This method of allocating the CTI consolidated current and deferred income taxes was systematic, rational and consistent with the asset and liability method. The separate return method represented a hypothetical computation assuming that the reported revenue and expenses of the Company were incurred by a separate taxable entity. Accordingly, the reported provision for income taxes and the related balance sheet accounts (including but not limited to the NOL deferred tax assets) did not equal the amounts that were allocable to the Company under the applicable consolidated federal and state tax laws. Further, as the Company did not have a tax-sharing agreement with CTI in place, the expected payable was treated as a dividend to the parent.
	From time to time, the Company has business transactions in which the tax consequences are uncertain. Significant judgment is required in assessing and estimating the tax consequences of these transactions. The Company prepares and files tax returns based on its interpretation of tax laws. In the normal course of business, the Company's tax returns are subject to examination by various taxing authorities. Such examinations may result in future tax, interest and penalty assessments. In determining the Company's tax provision for financial reporting purposes, the Company establishes a liability for uncertain tax positions unless such positions are determined to be more-likely-than-not of being sustained upon examination, based on their technical merits. That is, for financial reporting purposes, the Company only recognizes tax benefits that it believes are more-likely-than-not of being sustained and then recognizes the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. There is considerable judgment involved in determining whether positions taken on the tax return are more-likely-than-not of being sustained and determining the likelihood of various potential settlement outcomes.
	The Company adjusts its estimated liability for uncertain tax positions periodically because of new information discovered as a function of ongoing examinations by, and settlements with, the various taxing authorities, as well as changes in tax laws, regulations and interpretations. The combined tax provision of any given year includes adjustments to prior year income tax accruals that are considered appropriate as well as any related estimated interest. The Company's policy is to recognize, when applicable, interest and penalties on uncertain tax positions as part of income tax expense (see Note 19, Income Taxes).
	As part of the Company's accounting for business combinations, some of the purchase price is allocated to goodwill and intangible assets. Impairment expenses associated with goodwill are generally not tax deductible and will result in an increased effective income tax rate in the fiscal period any impairment is recorded. Amortization expenses associated with acquired intangible assets are generally not tax deductible pursuant to the Company's existing tax structure; however, deferred taxes have been recorded for non-deductible amortization expenses as a part of the purchase price allocation process. The Company has taken into account the allocation of these identified intangibles among different taxing jurisdictions, including those with nominal or zero percent tax rates, in establishing the related deferred tax liabilities. Under the FASB's guidance, the income tax benefit from future releases of the acquisition date valuation allowances or income tax contingencies, if any, are reflected in the income tax provision in the consolidated and combined statements of operations, rather than as an adjustment to the purchase price allocation.

Contingencies	'
	Contingencies
	Contingencies by their nature relate to uncertainties that require management to exercise judgment both in assessing the likelihood that a liability has been incurred as well as in estimating the amount of potential loss, if any. The Company accrues for costs relating to litigation, claims and other contingent matters when such liabilities become probable and reasonably estimable. Legal costs are expensed as incurred.
Restructuring	'
	Restructuring
	The Company has developed and implemented restructuring initiatives to improve efficiencies across the organization, reduce operating expenses, and better align its resources to market conditions. As a result of these plans, the Company has recorded restructuring expenses comprised principally of employee severance and associated termination costs related to the reduction of its workforce, office closures, losses on subleases and contract termination costs.
	The Company recognizes a liability for costs associated with an exit or disposal activity when the liability is incurred, as opposed to when management commits to an exit plan. The Company measures the liabilities associated with exit and disposal activities at fair value. One-time termination benefits are expensed at the date the employees are notified, unless the employees must provide future services beyond a minimum retention period, in which case the benefits are expensed ratably over the future service periods.
	Certain employees included in a termination plan may include employees in countries which require the Company by law to pay mandatory severance for involuntary termination based on years of service. A liability for the cost of the benefits would be recognized when payment is probable and estimable.
	The Company recognizes a liability for office closures measured at its fair value when the Company ceases using the rights conveyed by the contract, based on the remaining lease rentals, adjusted for the effects of any prepaid or deferred items recognized under the lease. This liability is further reduced by estimated sublease rentals that could be reasonably obtained for the property regardless of the intention of the lessee to sublease the premises.

Due to the interim tax requirements, the Company recorded $29.9 million of income tax expense for the three months ended July 31, 2013 and $11.3 million of income tax benefit for the three months ended October 31, 2013. The Company recorded net reversals of uncertain tax position liabilities of $16.5 million for the three months ended January 31, 2014.

[1]	Income from operations for the fiscal quarter ended January 31, 2014 was impacted by the recording of loss contract reserves of $7.1 million for three contracts accounted for under the Percentage of Completion method of revenue recognition.
[2]	Our tax provision is subject to significant year over year and quarter-to-quarter variability. Due to the interim tax requirements, the Company recorded $29.9 million of income tax expense for the three months ended July 31, 2013 and $11.3 million of income tax benefit for the three months ended October 31, 2013. The Company recorded net reversals of uncertain tax position liabilities of $16.5 million for the three months ended January 31, 2014.
[3]	Amounts may not total to annual earnings (loss) per share attributable to Comverse, Inc.'s stockholders because eachB quarter and year are calculated separately based on basic and diluted weighted-average common shares outstanding during that period.
