Description of Business and Summary of Significant Accounting Policies [Abstract]
Description of Business and Summary of Significant Accounting Policies	Note 1—Description of Business and Summary of Significant Accounting Policies Description of Business IDT Corporation (“IDT” or the “Company”) is a multinational holding company with operations primarily in the telecommunications and payment industries. The Company has two reportable business segments, Telecom Platform Services and Consumer Phone Services. Telecom Platform Services provides retail telecommunications and payment offerings as well as wholesale international long distance traffic termination. Consumer Phone Services provides consumer local and long distance services in certain U.S. states. Telecom Platform Services and Consumer Phone Services comprise the IDT Telecom division. Operating segments not reportable individually are included in All Other. Beginning in the second quarter of fiscal 2015, All Other includes Zedge Holdings, Inc. (“Zedge”), which provides a content platform for mobile device personalization including ringtones, wallpapers, home screen icons and game recommendations. All Other also includes the Company’s real estate holdings and other, smaller, businesses. Until the sale of Fabrix Systems Ltd. (“Fabrix”) in October 2014, All Other also included Fabrix, a software development company offering a cloud-based scale-out storage and computing platform optimized for big data, virtualization and media storage, processing and delivery. On July 31, 2013, the Company completed a pro rata distribution of the common stock of the Company’s subsidiary, Straight Path Communications Inc. (“Straight Path”), to the Company’s stockholders of record as of the close of business on July 25, 2013 (the “Straight Path Spin-Off”) (see Note 3). On October 28, 2011, the Company completed a pro rata distribution of the common stock of the Company’s subsidiary, Genie Energy Ltd. (“Genie”), to the Company’s stockholders of record as of the close of business on October 21, 2011 (the “Genie Spin-Off”). In August 2015, the Company’s Board of Directors approved a plan to reorganize the Company into three separate entities by spinning off two business units to its stockholders. The three separate companies are expected to consist of (1) IDT Telecom, (2) Zedge and (3) other holdings. The reorganization and the specific components are subject to change and both internal and third party contingencies, and must receive final approval from the Company’s Board of Directors and certain third parties. The Company is targeting completion of the reorganization in calendar year 2016. Basis of Consolidation and Accounting for Investments The method of accounting applied to long-term investments, whether consolidated, equity or cost, involves an evaluation of the significant terms of each investment that explicitly grant or suggest evidence of control or influence over the operations of the investee and also includes the identification of any variable interests in which the Company is the primary beneficiary. The consolidated financial statements include the Company’s controlled subsidiaries. In addition, the Company has not identified any variable interests in which the Company is the primary beneficiary. All significant intercompany accounts and transactions between the consolidated subsidiaries are eliminated. Investments in businesses that the Company does not control, but in which the Company has the ability to exercise significant influence over operating and financial matters, are accounted for using the equity method. Investments in which the Company does not have the ability to exercise significant influence over operating and financial matters are accounted for using the cost method. Investments in hedge funds are accounted for using the equity method unless the Company’s interest is so minor that it has virtually no influence over operating and financial policies, in which case these investments are accounted for using the cost method. At July 31, 2015 and 2014, the Company had $9.0 million and $9.4 million, respectively, in investments accounted for using the equity method, and $3.4 million and $1.8 million, respectively, in investments accounted for using the cost method. Equity and cost method investments are included in “Other current assets” or “Investments” in the accompanying consolidated balance sheets. The Company periodically evaluates its equity and cost method investments for impairment due to declines considered to be other than temporary. If the Company determines that a decline in fair value is other than temporary, then a charge to earnings is recorded in “Other (expense) income, net” in the accompanying consolidated statements of income, and a new basis in the investment is established. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates. Revenue Recognition Telephone service, which includes domestic and international long distance, local service, and wholesale carrier telephony services is recognized as revenue when services are provided, primarily based on usage and/or the assessment of fees. Revenue from Boss Revolution PIN-less international calling service and from sales of calling cards, net of customer discounts, is deferred until the service or the cards are used or, calling card administrative fees are imposed, thereby reducing the Company’s outstanding obligation to the customer, at which time revenue is recognized. Domestic and international airtime top-up revenue is recognized upon redemption. International airtime top-up enables customers to purchase airtime for a prepaid mobile telephone in another country. IDT Telecom enters into reciprocal transactions pursuant to which IDT Telecom is committed to purchase a specific number of minutes to specific destinations at specified rates, and the counterparty is committed to purchase from IDT Telecom a specific number of minutes to specific destinations at specified rates. The number of minutes purchased and sold in a reciprocal transaction is not necessarily equal. The rates in these reciprocal transactions are generally greater than prevailing market rates. In addition, IDT Telecom enters into transactions in which it swaps minutes with another carrier. The Company recognizes revenue and the related direct cost of revenue for these reciprocal and swap transactions based on the fair value of the minutes. Zedge revenues from traditional web/mobile web and Android/iOS applications are recognized based on blocks of impressions or ad views. Revenues from mobile games are recognized upon download by the end user. Revenue from Fabrix for software licenses and maintenance support was deferred and recognized on a straight-line basis from the date on which delivered orders were accepted by the customer over the period that the support was expected to be provided since sufficient vendor-specific objective evidence of fair value to allocate revenues to the various deliverables did not exist. Direct Cost of Revenues Direct cost of revenues for IDT Telecom consists primarily of termination and origination costs, toll-free costs, and network costs—including customer/carrier interconnect charges and leased fiber circuit charges. These costs include an estimate of charges for which invoices have not yet been received, and estimated amounts for pending disputes with other carriers. Direct cost of revenues for IDT Telecom also includes the cost of airtime top-up minutes. Direct cost of revenues for Zedge consists of ad server costs, web hosting charges, marketing automation and content filtering costs. Direct cost of revenues for Fabrix consisted primarily of customer support expenses. Direct cost of revenues excludes depreciation and amortization expense. Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Restricted Cash and Cash Equivalents The Company classifies the change in its restricted cash and cash equivalents as an operating activity in the accompanying consolidated statements of cash flows because the restrictions are directly related to the operations of IDT Financial Services, the Company’s Gibraltar-based bank, and IDT Telecom. Substantially Restricted Cash and Cash Equivalents The Company treats unrestricted cash and cash equivalents held by IDT Payment Services, which provides the Company’s international money transfer services in the United States and IDT Financial Services as substantially restricted and unavailable for other purposes. These balances are included in “Cash and cash equivalents” in the Company’s consolidated balance sheet (see Note 19). Marketable Securities The Company’s investments in marketable securities are classified as “available-for-sale.” Available-for-sale securities are required to be carried at their fair value, with unrealized gains and losses (net of income taxes) that are considered temporary in nature recorded in “Accumulated other comprehensive income” in the accompanying consolidated balance sheets. The Company uses the specific identification method in computing the gross realized gains and gross realized losses on the sales of marketable securities. The Company periodically evaluates its investments in marketable securities for impairment due to declines in market value considered to be other than temporary. Such impairment evaluations include, in addition to persistent, declining market prices, general economic and Company-specific evaluations. If the Company determines that a decline in market value is other than temporary, then a charge to operations is recorded in “Other (expense) income, net” in the accompanying consolidated statements of income and a new cost basis in the investment is established. Long-Lived Assets Equipment, buildings, computer software and furniture and fixtures are recorded at cost and are depreciated on a straight-line basis over their estimated useful lives, which range as follows: equipment—5, 7 or 20 years; buildings—40 years; computer software—2, 3 or 5 years and furniture and fixtures—5, 7 or 10 years. Leasehold improvements are recorded at cost and are depreciated on a straight-line basis over the term of their lease or their estimated useful lives, whichever is shorter. Costs associated with obtaining the right to use trademark and patents owned by third parties are capitalized and amortized on a straight-line basis over the term of the relevant trademark and patent licenses. The fair value of technology and domain names, customer lists, and trademark acquired in a business combination accounted for under the purchase method are amortized over their estimated useful lives as follows: technology and domain names are amortized on a straight-line basis over the estimated useful lives of 3 or 4 years; customer lists are amortized ratably over the approximately 15 year period of expected cash flows; and trademark is amortized on a straight-line basis over the 5 year period of expected cash flows. The Company tests the recoverability of its long-lived assets with finite useful lives whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. The Company tests for recoverability based on the projected undiscounted cash flows to be derived from such asset. If the projected undiscounted future cash flows are less than the carrying value of the asset, the Company will record an impairment loss, if any, based on the difference between the estimated fair value and the carrying value of the asset. The Company generally measures fair value by considering sale prices for similar assets or by discounting estimated future cash flows from such asset using an appropriate discount rate. Cash flow projections and fair value estimates require significant estimates and assumptions by management. Should the estimates and assumptions prove to be incorrect, the Company may be required to record impairments in future periods and such impairments could be material. Goodwill Goodwill is the excess of the acquisition cost of businesses over the fair value of the identifiable net assets acquired. Goodwill and other indefinite lived intangible assets are not amortized. These assets are reviewed annually (or more frequently under various conditions) for impairment using a fair value approach. The goodwill impairment assessment involves estimating the fair value of the reporting unit and comparing it to its carrying amount, which is known as Step 1. If the carrying value of the reporting unit exceeds its estimated fair value, Step 2 is performed to determine if an impairment of goodwill is required. The fair value of the reporting units is estimated using discounted cash flow methodologies, as well as considering third party market value indicators. Goodwill impairment is measured by the excess of the carrying amount of the reporting unit’s goodwill over its implied fair value. Calculating the fair value of the reporting units, and allocating the estimated fair value to all of the tangible assets, intangible assets and liabilities, requires significant estimates and assumptions by management. Should the estimates and assumptions regarding the fair value of the reporting units prove to be incorrect, the Company may be required to record impairments to its goodwill in future periods and such impairments could be material. The Company has the option to perform a qualitative assessment to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. However, the Company may elect to perform the two-step quantitative goodwill impairment test even if no indications of a potential impairment exist. For its reporting unit with zero or negative carrying amount, the Company performs Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining whether it is more likely than not that goodwill impairment exists, the Company considers whether there are any adverse qualitative factors indicating that impairment may exist. Derivative Instruments and Hedging Activities The Company records its derivatives instruments at their respective fair values. The accounting for changes in the fair value (that is, gains or losses) of a derivative instrument is dependent upon whether the derivative has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship. The Company does not designate its derivative instruments to qualify for hedge accounting, accordingly the instruments are recorded at fair value as a current asset or liability and any changes in fair value are recorded in the consolidated statements of income. Advertising Expense Cost of advertising is charged to selling, general and administrative expenses in the period in which it is incurred. In fiscal 2015, fiscal 2014 and fiscal 2013, advertising expense was $16.5 million, $17.2 million and $13.1 million, respectively. Research and Development Costs Costs for research and development are charged to expense as incurred. Research and development costs were incurred by Fabrix. Capitalized Internal Use Software Costs The Company capitalizes the cost of internal-use software that has a useful life in excess of one year. These costs consist of payments made to third parties and the salaries of employees working on such software development. Subsequent additions, modifications or upgrades to internal-use software are capitalized only to the extent that they allow the software to perform a task it previously did not perform. Software maintenance and training costs are expensed in the period in which they are incurred. Capitalized internal use software costs are amortized on a straight-line basis over their estimated useful lives. Amortization expense related to such capitalized software in fiscal 2015, fiscal 2014 and fiscal 2013 was $11.4 million, $8.8 million and $7.3 million, respectively. Unamortized capitalized internal use software costs at July 31, 2015 and 2014 were $18.8 million and $15.1 million, respectively. Repairs and Maintenance The Company charges the cost of repairs and maintenance, including the cost of replacing minor items not constituting substantial betterment, to selling, general and administrative expenses as these costs are incurred. Foreign Currency Translation Assets and liabilities of foreign subsidiaries denominated in foreign currencies are translated to U.S. Dollars at end-of-period rates of exchange, and their monthly results of operations are translated to U.S. Dollars at the average rates of exchange for that month. Gains or losses resulting from such foreign currency translations are recorded in “Accumulated other comprehensive income” in the accompanying consolidated balance sheets. Foreign currency transaction gains and losses are reported in “Other (expense) income, net” in the accompanying consolidated statements of income. Income Taxes The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the period in which related temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in its assessment of a valuation allowance. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date of such change. The Company uses a two-step approach for recognizing and measuring tax benefits taken or expected to be taken in a tax return. The Company determines whether it is more-likely-than-not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. In evaluating whether a tax position has met the more-likely-than-not recognition threshold, the Company presumes that the position will be examined by the appropriate taxing authority that has full knowledge of all relevant information. Tax positions that meet the more-likely-than-not recognition threshold are measured to determine the amount of tax benefit to recognize in the financial statements. The tax position is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Differences between tax positions taken in a tax return and amounts recognized in the financial statements will generally result in one or more of the following: an increase in a liability for income taxes payable, a reduction of an income tax refund receivable, a reduction in a deferred tax asset, or an increase in a deferred tax liability. The Company classifies interest and penalties on income taxes as a component of income tax expense. Contingencies The Company accrues for loss contingencies when both (a) information available prior to issuance of the financial statements indicates that it is probable that a liability had been incurred at the date of the financial statements and (b) the amount of loss can reasonably be estimated. When the Company accrues for loss contingencies and the reasonable estimate of the loss is within a range, the Company records its best estimate within the range. When no amount within the range is a better estimate than any other amount, the Company accrues the minimum amount in the range. The Company discloses an estimated possible loss or a range of loss when it is at least reasonably possible that a loss may have been incurred. Earnings Per Share Basic earnings per share is computed by dividing net income attributable to all classes of common stockholders of the Company by the weighted average number of shares of all classes of common stock outstanding during the applicable period. Diluted earnings per share is determined in the same manner as basic earnings per share, except that the number of shares is increased to include restricted stock still subject to risk of forfeiture and to assume exercise of potentially dilutive stock options using the treasury stock method, unless the effect of such increase is anti-dilutive. The weighted-average number of shares used in the calculation of basic and diluted earnings per share attributable to the Company’s common stockholders consists of the following: Year ended July 31 2015 2014 2013 Basic weighted-average number of shares 22,903 22,009 20,876 Effect of dilutive securities: Stock options 23 92 9 Non-vested restricted Class B common stock 321 836 1,430 Diluted weighted-average number of shares 23,247 22,937 22,315 The following outstanding stock options were excluded from the calculation of diluted earnings per share because the exercise price of the stock option was greater than the average market price of the Company’s stock during the period: Year ended July 31 2015 2014 2013 Shares excluded from the calculation of diluted earnings per share 136 70 611 Stock-Based Compensation The Company recognizes compensation expense for all of its grants of stock-based awards based on the estimated fair value on the grant date. Compensation cost for awards is recognized using the straight-line method over the vesting period. Stock-based compensation is included in selling, general and administrative expense. Vulnerability Due to Certain Concentrations Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash, cash equivalents, restricted cash and cash equivalents, marketable securities, investments in hedge funds and trade accounts receivable. The Company holds cash and cash equivalents at several major financial institutions, which often exceed FDIC insurance limits. Historically, the Company has not experienced any losses due to such concentration of credit risk. The Company’s temporary cash investments policy is to limit the dollar amount of investments with any one financial institution and monitor the credit ratings of those institutions. While the Company may be exposed to credit losses due to the nonperformance of the holders of its deposits, the Company does not expect the settlement of these transactions to have a material effect on its results of operations, cash flows or financial condition. Concentration of credit risk with respect to trade accounts receivable is limited due to the large number of customers in various geographic regions and industry segments comprising the Company’s customer base. No single customer accounted for more than 10% of consolidated revenues in fiscal 2015, fiscal 2014 or fiscal 2013. However, the Company’s five largest customers collectively accounted for 11.2%, 12.0% and 10.0% of its consolidated revenues from continuing operations in fiscal 2015, fiscal 2014 and fiscal 2013, respectively. The Company’s customers with the five largest receivables balances collectively accounted for 24.1% and 22.1% of the consolidated gross trade accounts receivable at July 31, 2015 and 2014, respectively. This concentration of customers increases the Company’s risk associated with nonpayment by those customers. In an effort to reduce such risk, the Company performs ongoing credit evaluations of its significant retail, wholesale and cable telephony customers. In addition, the Company attempts to mitigate the credit risk related to specific wholesale termination customers by also buying services from the customer, in order to create an opportunity to offset its payables and receivables and reduce its net trade receivable exposure risk. When it is practical to do so, the Company will increase its purchases from wholesale termination customers with receivable balances that exceed the Company’s applicable payables in order to maximize the offset and reduce its credit risk. Allowance for Doubtful Accounts The allowance for doubtful accounts reflects the Company’s best estimate of probable losses inherent in the accounts receivable balance. The allowance is determined based on known troubled accounts, historical experience and other currently available evidence. Doubtful accounts are written-off upon final determination that the trade accounts will not be collected. The change in the allowance for doubtful accounts is as follows: Year ended July 31 Balance at beginning of year Additions charged to costs and expenses Deductions (1) Balance at end of year 2015 Reserves deducted from accounts receivable: Allowance for doubtful accounts $ 11,507 $ 97 $ (5,959 ) $ 5,645 2014 Reserves deducted from accounts receivable: Allowance for doubtful accounts $ 13,079 $ 500 $ (2,072 ) $ 11,507 2013 Reserves deducted from accounts receivable: Allowance for doubtful accounts $ 13,044 $ 2,743 $ (2,708 ) $ 13,079 (1) Primarily uncollectible accounts written off, net of recoveries. Fair Value Measurements Fair value of financial and non-financial assets and liabilities is defined as an exit price, which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The three-tier hierarchy for inputs used to measure fair value, which prioritizes the inputs to valuation techniques used to measure fair value, is as follows: Level 1 – quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 – quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 – unobservable inputs based on the Company’s assumptions used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy. Recently Issued Accounting Standard Not Yet Adopted In May 2014, the Financial Accounting Standards Board and the International Accounting Standards Board jointly issued a comprehensive new revenue recognition standard that will supersede most of the current revenue recognition guidance under U.S. GAAP and International Financial Reporting Standards (“IFRS”). The goals of the revenue recognition project were to clarify and converge the revenue recognition principles under U.S. GAAP and IFRS and to develop guidance that would streamline and enhance revenue recognition requirements. The Company will adopt this standard on August 1, 2018. Entities have the option of using either a full retrospective or modified retrospective approach for the adoption of the standard. The Company is evaluating the impact that the standard will have on its consolidated financial statements.

Discontinued Operations [Abstract]
Discontinued Operations	Note 3—Discontinued Operations On July 31, 2013, the Company completed a pro rata distribution of the common stock of the Company’s subsidiary Straight Path to the Company’s stockholders of record as of the close of business on July 25, 2013. At the time of the Straight Path Spin-Off, Straight Path owned 100% of Straight Path Spectrum, Inc., which holds, leases and markets fixed wireless spectrum licenses, and 84.5% of Straight Path IP Group, Inc., which holds intellectual property primarily related to communications over the Internet and the licensing and other businesses related to this intellectual property. As of July 31, 2013, each of the Company’s stockholders received one share of Straight Path Class A common stock for every two shares of the Company’s Class A common stock and one share of Straight Path Class B common stock for every two shares of the Company’s Class B common stock held of record as of the close of business on July 25, 2013. Straight Path and its subsidiaries met the criteria to be reported as discontinued operations and accordingly, their assets, liabilities, results of operations and cash flows are classified as discontinued operations for all periods presented. The Company believes that the Straight Path Spin-Off was tax-free for the Company and the Company’s stockholders for U.S. federal income tax purposes under Section 355 of the Internal Revenue Code of 1986 (the “Code”). The Company received an opinion from Pryor Cashman LLP on the requirements for a tax-free distribution. Specifically, the opinion concluded that the distribution (i) should satisfy the business purpose requirement of the Code for a tax-free distribution, (ii) should not be viewed as being used principally as a device for the distribution of earnings and profits of the distributing corporation or the controlled corporation or both, and (iii) should not be viewed as part of a plan (or series of related transactions) pursuant to which one or more persons will acquire directly or indirectly stock representing a 50 percent or greater interest in the distributing corporation or controlled corporation within the meaning of the relevant section of the Code. In connection with the Straight Path Spin-Off, the Company funded Straight Path with a total of $15.0 million in aggregate cash and cash equivalents. Revenues, income before income taxes and net loss of Straight Path, which are included in discontinued operations, were as follows: Year ended July 31 2015 2014 2013 REVENUES $ — $ — $ 1,130 LOSS BEFORE INCOME TAXES $ — $ — $ (4,621 ) NET LOSS $ — $ — $ (4,634 )

In July 2015, the Company received 64,624 shares of Straight Path Class B common stock in connection with the lapsing of restrictions on awards of restricted stock (see Note 20). Proceeds from maturities and sales of available-for-sale securities were $24.1 million, $17.3 million and $1.7 million in fiscal 2015, fiscal 2014 and fiscal 2013, respectively. Realized losses from sales of available-for-sale securities were $0.1 million, nil and nil in fiscal 2015, fiscal 2014 and fiscal 2013, respectively. There were no realized gains from sales of available-for-sale securities in fiscal 2015, fiscal 2014 and fiscal 2013. In fiscal 2014, the Company recorded a loss of $0.1 million for the other than temporary decline in market value of its equity securities.

At July 31, 2015 and 2014, the Company had $9.1 million and $9.5 million, respectively, in investments in hedge funds, of which less than $0.1 million and $0.1 million, respectively, were included in “Other current assets” and $9.1 million and $9.4 million, respectively, were included in “Investments” in the accompanying consolidated balance sheets. The Company’s investments in hedge funds are accounted for using the equity method or the cost method, therefore investments in hedge funds are not measured at fair value. Fair Value of Other Financial Instruments The estimated fair value of the Company’s other financial instruments was determined using available market information or other appropriate valuation methodologies. However, considerable judgment is required in interpreting these data to develop estimates of fair value. Consequently, the estimates are not necessarily indicative of the amounts that could be realized or would be paid in a current market exchange. Cash and cash equivalents, restricted cash and cash equivalents—short-term, other current assets, revolving credit loan payable, customer deposits, note payable—current portion and other current liabilities. Restricted cash and cash equivalents—long-term. Other assets, note payable—long-term portion and other liabilities. The Company’s investments at July 31, 2015 and 2014 included investments in the equity of certain privately held entities and other investments that are accounted for at cost. It is not practicable to estimate the fair value of these investments because of the lack of a quoted market price for the shares of these entities, and the inability to estimate their fair value without incurring excessive cost. The carrying value of these investments was $3.4 million and $1.8 million at July 31, 2015 and 2014, respectively, which the Company believes was not impaired.

Derivative Instruments

Derivative Instruments [Abstract]
Derivative Instruments	Note 6—Derivative Instruments The primary risk managed by the Company using derivative instruments is foreign exchange risk. Foreign exchange forward contracts are entered into as hedges against unfavorable fluctuations in the U.S. dollar – Norwegian krone (“NOK”) exchange rate. Zedge is based in Norway and much of its operations are located in Norway. The Company does not apply hedge accounting to these contracts, therefore the changes in fair value are recorded in earnings. By using derivative instruments to mitigate exposures to changes in foreign exchange rates, the Company is exposed to credit risk from the failure of the counterparty to perform under the terms of the contract. The Company minimizes the credit or repayment risk by entering into transactions with high-quality counterparties. The Company’s outstanding contracts at July 31, 2015 were as follows: Settlement Date U.S. Dollar Amount NOK Amount September 2015 750,000 6,163,000 November 2015 2,729,000 22,169,000 January 2016 3,000,000 24,257,000 May 2016 1,000,000 8,239,000 July 2016 1,000,000 8,200,000 The fair value of outstanding derivative instruments recorded as assets in the accompanying consolidated balance sheets were as follows: July 31 (in thousands) 2015 2014 Asset Derivatives Balance Sheet Location Derivatives not designated or not qualifying as hedging instruments: Foreign exchange forwards Other current assets $ 38 $ — The fair value of outstanding derivative instruments recorded as liabilities in the accompanying consolidated balance sheets were as follows: July 31 (in thousands) 2015 2014 Liability Derivatives Balance Sheet Location Derivatives not designated or not qualifying as hedging instruments: Foreign exchange forwards Other current liabilities $ 39 $ — The effects of derivative instruments on the consolidated statements of operations were as follows: Amount of Gain (Loss) Year ended July 31, (in thousands) 2015 2014 2013 Derivatives not designated or not qualifying as hedging instruments Location of Gain (Loss) Recognized on Derivatives Foreign exchange forwards Other (expense) income, net $ (58 ) $ — $ —

The following facts and circumstances indicated that the fair value of the building and improvements may be less than their carrying value at that time: (1) the building was not occupied and, at the time, the Company did not expect to occupy it, (2) economic uncertainty and sluggish leasing activity stalled a recovery of the real estate market in Newark, (3) there were no potential tenants, (4) no sale of the building had been completed and there were no other likely buyers, (5) the building would be expensive to redevelop and (6) the building was expected to remain vacant for the foreseeable future. The Company determined the fair value of the building and improvements based on estimates of an owner/user’s market rental rate net of costs of improvements and tenant work as well as the estimated value to an investor/developer after deducting costs of improvements and costs to achieve full occupancy. This fair value measurement was classified as Level 2 of the fair value hierarchy. In fiscal 2014, the Company began renovations of the first four floors of its 520 Broad Street building in order to move its personnel and offices located at 550 Broad Street, Newark, New Jersey to 520 Broad Street. In April and May 2015, the Company moved its Newark operations back into its building at 520 Broad Street and vacated its leased office space at 550 Broad Street. At July 31, 2015 and 2014, the carrying value of the land, building and improvements at 520 Broad Street after the impairment charge was $44.4 million and $37.7 million, respectively. Depreciation and amortization expense of property, plant and equipment was $18.0 million, $15.7 million and $14.3 million in fiscal 2015, fiscal 2014 and fiscal 2013, respectively.

The Company recorded a benefit from income taxes of $4.1 million in fiscal 2014 from the full recognition of the IDT Global deferred tax assets. The differences between income taxes expected at the U.S. federal statutory income tax rate and income taxes provided are as follows: Year ended July 31 2015 2014 2013 U.S. federal income tax at statutory rate $ (32,271 ) $ (8,747 ) $ (11,883 ) Valuation allowance — 4,110 — Foreign tax rate differential 25,757 961 (5,073 ) Nondeductible expenses 659 761 714 Other (73 ) 7 50 Prior year tax (expense) benefit — (960 ) 921 State and local income tax, net of federal benefit (160 ) (114 ) (601 ) PROVISION FOR INCOME TAXES $ (6,088 ) $ (3,982 ) $ (15,872 ) At July 31, 2015, the Company had federal and state net operating loss carryforwards of approximately $170 million. This carry-forward loss is available to offset future U.S. federal and state taxable income. The net operating loss carryforwards will start to expire in fiscal 2016, with fiscal 2015’s loss expiring in fiscal 2036. The Company has foreign net operating losses of approximately $173 million, of which approximately $117 million does not expire and approximately $56 million expires in two to nine years. These foreign net operating losses are available to offset future taxable income in the countries in which the losses were incurred. The Company’s subsidiary, Net2Phone, which provides voice over Internet protocol communications services, has additional federal net operating losses of approximately $84 million, which will expire through fiscal 2027. With the reacquisition of Net2Phone by the Company in March 2006, its losses were limited under Internal Revenue Code Section 382 to approximately $7 million per year. The net operating losses do not include any excess benefits related to stock options or restricted stock. The Company has not recorded U.S. income tax expense for foreign earnings, as such earnings are permanently reinvested outside the United States. The cumulative undistributed foreign earnings are included in accumulated deficit in the Company’s consolidated balance sheets, and consisted of approximately $353 million at July 31, 2015. Upon distribution of these foreign earnings to the Company’s domestic entities, the Company may be subject to U.S. income taxes and withholding of foreign taxes, however, it is not practicable to determine the amount, if any, which would be paid. The change in the valuation allowance is as follows: Year ended July 31 Balance at Additions Deductions Balance at 2015 Reserves deducted from deferred income taxes, net: Valuation allowance $ 151,975 $ 3,418 $ — $ 155,393 2014 Reserves deducted from deferred income taxes, net: Valuation allowance $ 167,328 $ — $ (15,353 ) $ 151,975 2013 Reserves deducted from deferred income taxes, net: Valuation allowance $ 204,977 $ 462 $ (38,111 ) $ 167,328 The table below summarizes the change in the balance of unrecognized income tax benefits: Year ended July 31 2015 2014 2013 Balance at beginning of year $ — $ 356 $ — Additions based on tax positions related to the current year — — — Additions for tax positions of prior years — — 356 Reductions for tax positions of prior years — — — Settlements — (356 ) — Lapses of statutes of limitations — — — Balance at end of year $ — $ — $ 356 At July 31, 2015, the Company did not have any unrecognized income tax benefits and did not expect any changes in the next twelve months. If the Company recognized any unrecognized income tax benefits, it would affect the effective tax rate. In fiscal 2015, fiscal 2014 and fiscal 2013, the Company did not record any interest and penalties on income taxes. As of July 31, 2015 and 2014, there was no accrued interest included in current income taxes payable.

Stock-Based Compensation [Abstract]
Stock-Based Compensation	Note 17—Stock-Based Compensation Stock-Based Compensation Plans On December 15, 2014, the Company’s stockholders ratified the 2015 Stock Option and Incentive Plan, which became effective on January 1, 2015. Shares available for future grants under the Company’s 2005 Stock Option and Incentive Plan are no longer available. The 2015 Stock Option and Incentive Plan is intended to provide incentives to officers, employees, directors and consultants of the Company, including stock options, stock appreciation rights, limited rights, deferred stock units, and restricted stock. At July 31, 2015, the Company had 0.5 million shares of Class B common stock reserved for award under its 2015 Stock Option and Incentive Plan and 0.1 million shares were available for future grants. In fiscal 2015, fiscal 2014 and fiscal 2013, there was no income tax benefit resulting from tax deductions in excess of the compensation cost recognized for the Company’s stock-based compensation. Stock Options Option awards are generally granted with an exercise price equal to the market price of the Company’s stock on the date of grant. Option awards generally vest on a graded basis over three years of service and have ten-year contractual terms. The fair value of stock options was estimated on the date of the grant using a Black-Scholes valuation model and the assumptions in the following table. No option awards were granted in fiscal 2014 and fiscal 2013. Expected volatility is based on historical volatility of the Company’s Class B common stock and other factors. The Company uses historical data on exercise of stock options, post vesting forfeitures and other factors to estimate the expected term of the stock-based payments granted. The risk free rate is based on the U.S. Treasury yield curve in effect at the time of grant. Year ended July 31 2015 ASSUMPTIONS Average risk-free interest rate 1.63 % Expected dividend yield — Expected volatility 51.4 % Expected term 6.0 years A summary of stock option activity for the Company is as follows: Number of Weighted- Weighted- Aggregate Outstanding at July 31, 2014 611 $ 14.24 Granted 135 15.97 Exercised (245 ) 13.98 Cancelled / Forfeited (77 ) 16.22 OUTSTANDING AT JULY 31, 2015 424 $ 14.58 7.4 $ 1,167 EXERCISABLE AT JULY 31, 2015 147 $ 17.02 4.1 $ 132 The weighted-average grant date fair value of options granted by the Company during fiscal 2015 was $7.94. The total intrinsic value of options exercised during fiscal 2015, fiscal 2014 and fiscal 2013 was $1.3 million, $0.2 million and $0.2 million, respectively. At July 31, 2015, there was $1.7 million of total unrecognized compensation cost related to non-vested stock options, which is expected to be recognized over a weighted-average period of 1.8 years. In August 2013, in connection with the Straight Path Spin-Off, the exercise price of each outstanding option to purchase the Company’s Class B common stock was reduced by 15.29% of the exercise price based on the change in the trading price of the Company’s Class B common stock following the Straight Path Spin-Off. Further, each holder of options to purchase the Company’s Class B common stock shared ratably in a pool of options to purchase 32,155 shares of Straight Path Class B common stock. The Company accounted for the August 2013 reduction in the exercise price of the Company’s outstanding stock options and the grant of new options in Straight Path as a modification. The Company determined that there was no incremental value from the modification, and therefore, the Company did not record a stock-based compensation charge. Restricted Stock The fair value of restricted shares of the Company’s Class B common stock is determined based on the closing price of the Company’s Class B common stock on the grant date. Share awards generally vest on a graded basis over three years of service. A summary of the status of the Company’s grants of restricted shares of Class B common stock is presented below: (in thousands) Number of Weighted- Non-vested shares at July 31, 2014 540 $ 13.00 Granted 366 17.36 Vested (454 ) 12.34 Forfeited (32 ) 13.04 NON-VESTED SHARES AT JULY 31, 2015 420 $ 17.50 At July 31, 2015, there was $6.1 million of total unrecognized compensation cost related to non-vested stock-based compensation arrangements, which is expected to be recognized over a weighted-average period of 1.5 years. The total grant date fair value of shares vested in fiscal 2015, fiscal 2014 and fiscal 2013 was $5.6 million, $8.7 million and $3.5 million, respectively. Straight Path IP Group Stock On September 24, 2012, the Company’s Board of Directors approved a grant of 10% of the equity of the Company’s former subsidiary, Straight Path IP Group, to Howard Jonas. These Straight Path IP Group shares vested immediately. The Company recorded stock-based compensation expense of $0.7 million in fiscal 2013 for the grant of these shares, based on the estimated fair value of the shares on the grant date.

Commitments and Contingencies	Note 19— Commitments and Contingencies Legal Proceedings On May 5, 2004, the Company filed a complaint in the Supreme Court of the State of New York, County of New York, seeking injunctive relief and damages against Tyco Group, S.A.R.L., Tyco Telecommunications (US) Inc. (f/k/a TyCom (US) Inc.), Tyco International, Ltd., Tyco International (US) Inc., and TyCom Ltd. (collectively “Tyco”). The Company alleged that Tyco breached a settlement agreement that it had entered into with the Company to resolve certain disputes and civil actions among the parties. The Company alleged that Tyco did not provide the Company, as required under the settlement agreement, free of charge and for the Company’s exclusive use, a 15-year indefeasible right to use four Wavelengths in Ring Configuration (as defined in the settlement agreement) on a global undersea fiber optic network that Tyco was deploying at that time. After extensive proceedings, including several decisions and appeals, the New York Court of Appeals affirmed a lower court decision to dismiss the Company’s claim and denied the Company’s motion for re-argument of that decision. On June 23, 2015, the Company filed a new summons and complaint against Tyco in the Supreme Court of the State of New York, County of New York alleging that Tyco breached the settlement agreement. In September 2015, Tyco filed a motion to dismiss the complaint. The parties have stipulated to a briefing schedule. In addition to the foregoing, the Company is subject to other legal proceedings that have arisen in the ordinary course of business and have not been finally adjudicated. Although there can be no assurance in this regard, the Company believes that none of the other legal proceedings to which the Company is a party will have a material adverse effect on the Company’s results of operations, cash flows or financial condition. Purchase Commitments The Company had purchase commitments of $2.8 million as of July 31, 2015, which includes commitments related to the renovations of the first four floors of the Company’s building located at 520 Broad Street, Newark, New Jersey.

Related Party Transactions [Abstract]
Related Party Transactions	Note 20—Related Party Transactions The Company entered into various agreements with Straight Path prior to the Straight Path Spin-Off including (1) a Separation and Distribution Agreement to effect the separation and provide a framework for the Company’s relationship with Straight Path after the spin-off, (2) a Tax Separation Agreement, which sets forth the responsibilities of the Company and Straight Path with respect to, among other things, liabilities for federal, state, local and foreign taxes for periods before and including the spin-off, the preparation and filing of tax returns for such periods and disputes with taxing authorities regarding taxes for such periods, and (3) a Transition Services Agreement, which provides for certain services to be performed by the Company to facilitate Straight Path’s transition into a separate publicly-traded company. These agreements provide for, among other things, the allocation between the Company and Straight Path of employee benefits, taxes and other liabilities and obligations attributable to periods prior to the spin-off, and provision of certain services by the Company to Straight Path following the spin-off, including services relating to human resources and employee benefits administration, treasury, accounting, tax, external reporting, and legal. Straight Path transitioned accounting and external reporting services from the Company to a third party in the first quarter of fiscal 2015. In addition, the Company and Straight Path have entered into a license agreement whereby each of the Company, Straight Path and their subsidiaries granted and will grant a license to the other to utilize patents held by each entity. The Separation and Distribution Agreement also includes that the Company is obligated to reimburse Straight Path for the payment of any liabilities of Straight Path arising or related to the period prior to the Straight Path Spin-Off. The following table summarizes the change in the balance of the Company’s estimated liability to Straight Path, which is included in “Other current liabilities” in the accompanying consolidated balance sheet: Year ended July 31 (in thousands) 2015 2014 Balance at beginning of year $ 1,860 $ 931 Additional liability 1,793 1,930 Adjustments (556 ) — Payments (2,811 ) (1,001 ) Balance at end of year $ 286 $ 1,860 Pursuant to the Separation and Distribution Agreement, the Company indemnifies Straight Path and Straight Path indemnifies the Company for losses related to the failure of the other to pay, perform or otherwise discharge, any of the liabilities and obligations set forth in the agreement. Pursuant to the Tax Separation Agreement, the Company indemnifies Straight Path from all liability for taxes of Straight Path or any of its subsidiaries or relating to the Straight Path business with respect to taxable periods ending on or before the Straight Path Spin-Off, from all liability for taxes of the Company, other than Straight Path and its subsidiaries, for any taxable period, and from all liability for taxes due to the Straight Path Spin-Off. The Company charged Straight Path $1.1 million and $0.8 million in fiscal 2015 and fiscal 2014, respectively, for services provided pursuant to the Transition Services Agreement and other items. At July 31, 2015 and 2014, other current assets reported in the Company’s consolidated balance sheet included receivables from Straight Path of nil and $29,000, respectively. In July 2015, the Company received 64,624 shares of Straight Path Class B common stock in connection with the lapsing of restrictions on awards of Straight Path restricted stock to certain of the Company’s employees (see Note 4). As part of the Straight Path Spin-Off, holders of the Company’s restricted Class B common stock received, in respect of those restricted shares, one share of Straight Path’s Class B common stock for every two restricted shares of the Company that they held as of the record date for the Straight Path Spin-Off. The Company received the Straight Path shares in exchange for the payment of an aggregate of $2.1 million for the employees’ tax withholding obligations upon the vesting event. The number of shares was determined based on their fair market value on the trading day immediately prior to the vesting date. The Company entered into various agreements with Genie prior to the Genie Spin-Off including a Separation and Distribution Agreement to effect the separation and provide a framework for the Company’s relationship with Genie after the spin-off, and a Transition Services Agreement, which provides for certain services to be performed by the Company and Genie to facilitate Genie’s transition into a separate publicly-traded company. These agreements provide for, among other things, (1) the allocation between the Company and Genie of employee benefits, taxes and other liabilities and obligations attributable to periods prior to the spin-off, (2) transitional services to be provided by the Company relating to human resources and employee benefits administration, (3) the allocation of responsibilities relating to employee compensation and benefit plans and programs and other related matters, (4) finance, accounting, tax, internal audit, facilities, external reporting, investor relations and legal services to be provided by the Company to Genie following the spin-off and (5) specified administrative services to be provided by Genie to certain of the Company’s foreign subsidiaries. In addition, the Company entered into a Tax Separation Agreement with Genie, which sets forth the responsibilities of the Company and Genie with respect to, among other things, liabilities for federal, state, local and foreign taxes for periods before and including the spin-off, the preparation and filing of tax returns for such periods and disputes with taxing authorities regarding taxes for such periods. Pursuant to the Separation and Distribution Agreement, the Company indemnifies Genie and Genie indemnifies the Company for losses related to the failure of the other to pay, perform or otherwise discharge, any of the liabilities and obligations set forth in the agreement.

The Company’s Chairman of the Board and former Chief Executive Officer, Howard S. Jonas, is the controlling stockholder and Chairman of the Board of Genie. The Company charged Genie $3.6 million, $3.1 million and $3.8 million in fiscal 2015, fiscal 2014 and fiscal 2013, respectively, for services provided pursuant to the Transition Services Agreement and other items, net of the amounts charged by Genie to the Company. At July 31, 2015 and 2014, other current assets reported in the Company’s consolidated balance sheet included receivables from Genie of $0.5 million. IDT Energy, Inc., a subsidiary of Genie, supplied electricity to the Company’s facilities in Piscataway, New Jersey, and Newark, New Jersey through January 2013. IDT Energy also supplied natural gas to the Company’s Newark, New Jersey building until April 2013, and IDT Energy supplies natural gas to the Company’s facility in Piscataway, New Jersey. In fiscal 2014 and fiscal 2013, IDT Energy, Inc. billed the Company $16,000 and $21,000, respectively. The Company provides office space, certain connectivity and other services to Jonas Media Group, a publishing firm owned by Howard Jonas. Billings for such services were $21,000, $18,000 and $27,000 in fiscal 2015, fiscal 2014 and fiscal 2013, respectively. The balance owed to the Company by Jonas Media Group was $7,000 and $4,000 as of July 31, 2015 and 2014, respectively. The Company obtains insurance policies from several insurance brokers, one of which is IGM Brokerage Corp. (“IGM”). IGM was, until his death in October 2009, owned by Irwin Jonas, father of Howard Jonas, and the Company’s General Counsel, Joyce J. Mason. IGM is currently owned by Irwin Jonas’ widow—the mother of Howard Jonas and Joyce Mason. Jonathan Mason, husband of Joyce Mason and brother-in-law of Howard Jonas, provides insurance brokerage services via IGM. Based on information the Company received from IGM, the Company believes that IGM received commissions and fees from payments made by the Company to third party brokers in the aggregate amounts of $20,000 in fiscal 2015, $20,000 in fiscal 2014 and $15,000 in fiscal 2013, which fees and commissions inured to the benefit of Mr. Mason. Neither Howard Jonas nor Joyce Mason has any ownership or other interest in IGM or the commissions paid to IGM other than via the familial relationships with their mother and Jonathan Mason. Mason and Company Consulting, LLC (“Mason and Co.”), a company owned solely by Jonathan Mason, receives an annual fee for the insurance brokerage referral and placement of the Company’s health benefit plan with Brown & Brown Metro, Inc. Based on information the Company received from Jonathan Mason, the Company believes that Mason and Co. received from Brown & Brown Metro, Inc. commissions and fees from payments made by the Company in the amount of $18,000 in fiscal 2015, $18,000 in fiscal 2014 and $24,000 in fiscal 2013. Neither Howard Jonas nor Joyce Mason has any ownership or other interest in Mason and Co. or the commissions paid to Mason and Co., other than via the familial relationships with Jonathan Mason.

Howard Jonas and Shmuel Jonas, the Company’s Chief Executive Officer, and the son of Howard Jonas, are members of the limited liability company that owns the building. For the six month period from May 1, 2012 to October 31, 2012, IDT Domestic Telecom was charged aggregate rent of $34,512. The parties entered into a new lease, which became effective November 1, 2012 and had a one-year term, with a one-year renewal option for IDT Domestic Telecom with the same terms. Aggregate annual rent under the new lease was $69,025. The Company had net loans receivable outstanding from employees aggregating $0.3 million and $0.2 million at July 31, 2015 and 2014, respectively, which are included in “Other current assets” in the accompanying consolidated balance sheets.

Business Segment Information [Abstract]
Business Segment Information	Note 22—Business Segment Information The Company has two reportable business segments, Telecom Platform Services and Consumer Phone Services. Operating segments that are not reportable individually are included in All Other. The Company’s reportable segments are distinguished by types of service, customers and methods used to provide their services. The operating results of these business segments are regularly reviewed by the Company’s chief operating decision maker. The Telecom Platform Services segment provides retail telecommunications and payment offerings as well as wholesale international long distance traffic termination. The Consumer Phone Services segment provides consumer local and long distance services in certain U.S. states. Telecom Platform Services and Consumer Phone Services comprise the IDT Telecom division. Beginning in the second quarter of fiscal 2015, All Other includes Zedge, which provides a content platform for mobile device personalization including ringtones, wallpapers, home screen icons and game recommendations. Comparative results have been reclassified and restated as if Zedge was included in All Other in all periods presented. All Other also includes the Company’s real estate holdings and other, smaller, businesses. Until the sale of Fabrix in October 2014, All Other also included Fabrix, a software development company offering a cloud-based scale-out storage and computing platform optimized for big data, virtualization and media storage, processing and delivery. Corporate costs include certain services, such as compensation, consulting fees, treasury and accounts payable, tax and accounting services, human resources and payroll, corporate purchasing, corporate governance including Board of Directors’ fees, internal and external audit, investor relations, corporate insurance, corporate legal, business development, and other corporate-related general and administrative expenses including, among others, facilities costs, charitable contributions and travel, as well as depreciation expense on corporate assets. Corporate does not generate any revenues, nor does it incur any direct cost of revenues. The accounting policies of the segments are the same as the accounting policies of the Company as a whole. The Company evaluates the performance of its business segments based primarily on income (loss) from operations. IDT Telecom depreciation and amortization are allocated to Telecom Platform Services and Consumer Phone Services because the related assets are not tracked separately by segment. There are no other significant asymmetrical allocations to segments. Operating results for the business segments of the Company are as follows: (in thousands) Telecom Consumer All Other Corporate Total Year ended July 31, 2015 Revenues $ 1,572,744 $ 8,629 $ 15,404 $ — $ 1,596,777 Income (loss) from operations 26,951 1,259 77,969 (13,129 ) 93,050 Depreciation and amortization 16,169 — 2,243 6 18,418 Severance 7,696 — 35 632 8,363 Gain on sale of interest in Fabrix Systems Ltd. — — 76,864 — 76,864 Other operating loss — — — (1,552 ) (1,552 ) Year ended July 31, 2014 Revenues $ 1,615,570 $ 11,023 $ 24,948 $ — $ 1,651,541 Income (loss) from operations 45,062 1,797 (1,735 ) (15,284 ) 29,840 Depreciation and amortization 13,776 — 2,512 30 16,318 Other operating gains (losses), net 650 — 638 (453 ) 835 Year ended July 31, 2013 Revenues $ 1,588,071 $ 14,514 $ 18,032 $ — $ 1,620,617 Income (loss) from operations 48,661 1,824 (7,093 ) (14,001 ) 29,391 Depreciation and amortization 12,342 1 2,471 96 14,910 Impairment of building and improvements — — 4,359 — 4,359 Other operating gains 9,251 — — — 9,251 Telecom Platform Services’ income from operations in fiscal 2013 included net gains of $9.3 million related to legal matters.

Description of Business and Summary of Significant Accounting Policies [Abstract]
Description of Business	Description of Business IDT Corporation (“IDT” or the “Company”) is a multinational holding company with operations primarily in the telecommunications and payment industries. The Company has two reportable business segments, Telecom Platform Services and Consumer Phone Services. Telecom Platform Services provides retail telecommunications and payment offerings as well as wholesale international long distance traffic termination. Consumer Phone Services provides consumer local and long distance services in certain U.S. states. Telecom Platform Services and Consumer Phone Services comprise the IDT Telecom division. Operating segments not reportable individually are included in All Other. Beginning in the second quarter of fiscal 2015, All Other includes Zedge Holdings, Inc. (“Zedge”), which provides a content platform for mobile device personalization including ringtones, wallpapers, home screen icons and game recommendations. All Other also includes the Company’s real estate holdings and other, smaller, businesses. Until the sale of Fabrix Systems Ltd. (“Fabrix”) in October 2014, All Other also included Fabrix, a software development company offering a cloud-based scale-out storage and computing platform optimized for big data, virtualization and media storage, processing and delivery. On July 31, 2013, the Company completed a pro rata distribution of the common stock of the Company’s subsidiary, Straight Path Communications Inc. (“Straight Path”), to the Company’s stockholders of record as of the close of business on July 25, 2013 (the “Straight Path Spin-Off”) (see Note 3). On October 28, 2011, the Company completed a pro rata distribution of the common stock of the Company’s subsidiary, Genie Energy Ltd. (“Genie”), to the Company’s stockholders of record as of the close of business on October 21, 2011 (the “Genie Spin-Off”). In August 2015, the Company’s Board of Directors approved a plan to reorganize the Company into three separate entities by spinning off two business units to its stockholders. The three separate companies are expected to consist of (1) IDT Telecom, (2) Zedge and (3) other holdings. The reorganization and the specific components are subject to change and both internal and third party contingencies, and must receive final approval from the Company’s Board of Directors and certain third parties. The Company is targeting completion of the reorganization in calendar year 2016.
Basis of Consolidation and Accounting for Investments	Basis of Consolidation and Accounting for Investments The method of accounting applied to long-term investments, whether consolidated, equity or cost, involves an evaluation of the significant terms of each investment that explicitly grant or suggest evidence of control or influence over the operations of the investee and also includes the identification of any variable interests in which the Company is the primary beneficiary. The consolidated financial statements include the Company’s controlled subsidiaries. In addition, the Company has not identified any variable interests in which the Company is the primary beneficiary. All significant intercompany accounts and transactions between the consolidated subsidiaries are eliminated. Investments in businesses that the Company does not control, but in which the Company has the ability to exercise significant influence over operating and financial matters, are accounted for using the equity method. Investments in which the Company does not have the ability to exercise significant influence over operating and financial matters are accounted for using the cost method. Investments in hedge funds are accounted for using the equity method unless the Company’s interest is so minor that it has virtually no influence over operating and financial policies, in which case these investments are accounted for using the cost method. At July 31, 2015 and 2014, the Company had $9.0 million and $9.4 million, respectively, in investments accounted for using the equity method, and $3.4 million and $1.8 million, respectively, in investments accounted for using the cost method. Equity and cost method investments are included in “Other current assets” or “Investments” in the accompanying consolidated balance sheets. The Company periodically evaluates its equity and cost method investments for impairment due to declines considered to be other than temporary. If the Company determines that a decline in fair value is other than temporary, then a charge to earnings is recorded in “Other (expense) income, net” in the accompanying consolidated statements of income, and a new basis in the investment is established.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates.
Revenue Recognition	Revenue Recognition Telephone service, which includes domestic and international long distance, local service, and wholesale carrier telephony services is recognized as revenue when services are provided, primarily based on usage and/or the assessment of fees. Revenue from Boss Revolution PIN-less international calling service and from sales of calling cards, net of customer discounts, is deferred until the service or the cards are used or, calling card administrative fees are imposed, thereby reducing the Company’s outstanding obligation to the customer, at which time revenue is recognized. Domestic and international airtime top-up revenue is recognized upon redemption. International airtime top-up enables customers to purchase airtime for a prepaid mobile telephone in another country. IDT Telecom enters into reciprocal transactions pursuant to which IDT Telecom is committed to purchase a specific number of minutes to specific destinations at specified rates, and the counterparty is committed to purchase from IDT Telecom a specific number of minutes to specific destinations at specified rates. The number of minutes purchased and sold in a reciprocal transaction is not necessarily equal. The rates in these reciprocal transactions are generally greater than prevailing market rates. In addition, IDT Telecom enters into transactions in which it swaps minutes with another carrier. The Company recognizes revenue and the related direct cost of revenue for these reciprocal and swap transactions based on the fair value of the minutes. Zedge revenues from traditional web/mobile web and Android/iOS applications are recognized based on blocks of impressions or ad views. Revenues from mobile games are recognized upon download by the end user. Revenue from Fabrix for software licenses and maintenance support was deferred and recognized on a straight-line basis from the date on which delivered orders were accepted by the customer over the period that the support was expected to be provided since sufficient vendor-specific objective evidence of fair value to allocate revenues to the various deliverables did not exist.
Direct Cost of Revenues	Direct Cost of Revenues Direct cost of revenues for IDT Telecom consists primarily of termination and origination costs, toll-free costs, and network costs—including customer/carrier interconnect charges and leased fiber circuit charges. These costs include an estimate of charges for which invoices have not yet been received, and estimated amounts for pending disputes with other carriers. Direct cost of revenues for IDT Telecom also includes the cost of airtime top-up minutes. Direct cost of revenues for Zedge consists of ad server costs, web hosting charges, marketing automation and content filtering costs. Direct cost of revenues for Fabrix consisted primarily of customer support expenses. Direct cost of revenues excludes depreciation and amortization expense.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.
Restricted Cash and Cash Equivalents	Restricted Cash and Cash Equivalents The Company classifies the change in its restricted cash and cash equivalents as an operating activity in the accompanying consolidated statements of cash flows because the restrictions are directly related to the operations of IDT Financial Services, the Company’s Gibraltar-based bank, and IDT Telecom.
Substantially Restricted Cash and Cash Equivalents	Substantially Restricted Cash and Cash Equivalents The Company treats unrestricted cash and cash equivalents held by IDT Payment Services, which provides the Company’s international money transfer services in the United States and IDT Financial Services as substantially restricted and unavailable for other purposes. These balances are included in “Cash and cash equivalents” in the Company’s consolidated balance sheet (see Note 19).
Marketable Securities	Marketable Securities The Company’s investments in marketable securities are classified as “available-for-sale.” Available-for-sale securities are required to be carried at their fair value, with unrealized gains and losses (net of income taxes) that are considered temporary in nature recorded in “Accumulated other comprehensive income” in the accompanying consolidated balance sheets. The Company uses the specific identification method in computing the gross realized gains and gross realized losses on the sales of marketable securities. The Company periodically evaluates its investments in marketable securities for impairment due to declines in market value considered to be other than temporary. Such impairment evaluations include, in addition to persistent, declining market prices, general economic and Company-specific evaluations. If the Company determines that a decline in market value is other than temporary, then a charge to operations is recorded in “Other (expense) income, net” in the accompanying consolidated statements of income and a new cost basis in the investment is established.
Long-Lived Assets	Long-Lived Assets Equipment, buildings, computer software and furniture and fixtures are recorded at cost and are depreciated on a straight-line basis over their estimated useful lives, which range as follows: equipment—5, 7 or 20 years; buildings—40 years; computer software—2, 3 or 5 years and furniture and fixtures—5, 7 or 10 years. Leasehold improvements are recorded at cost and are depreciated on a straight-line basis over the term of their lease or their estimated useful lives, whichever is shorter. Costs associated with obtaining the right to use trademark and patents owned by third parties are capitalized and amortized on a straight-line basis over the term of the relevant trademark and patent licenses. The fair value of technology and domain names, customer lists, and trademark acquired in a business combination accounted for under the purchase method are amortized over their estimated useful lives as follows: technology and domain names are amortized on a straight-line basis over the estimated useful lives of 3 or 4 years; customer lists are amortized ratably over the approximately 15 year period of expected cash flows; and trademark is amortized on a straight-line basis over the 5 year period of expected cash flows. The Company tests the recoverability of its long-lived assets with finite useful lives whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. The Company tests for recoverability based on the projected undiscounted cash flows to be derived from such asset. If the projected undiscounted future cash flows are less than the carrying value of the asset, the Company will record an impairment loss, if any, based on the difference between the estimated fair value and the carrying value of the asset. The Company generally measures fair value by considering sale prices for similar assets or by discounting estimated future cash flows from such asset using an appropriate discount rate. Cash flow projections and fair value estimates require significant estimates and assumptions by management. Should the estimates and assumptions prove to be incorrect, the Company may be required to record impairments in future periods and such impairments could be material.
Goodwill	Goodwill Goodwill is the excess of the acquisition cost of businesses over the fair value of the identifiable net assets acquired. Goodwill and other indefinite lived intangible assets are not amortized. These assets are reviewed annually (or more frequently under various conditions) for impairment using a fair value approach. The goodwill impairment assessment involves estimating the fair value of the reporting unit and comparing it to its carrying amount, which is known as Step 1. If the carrying value of the reporting unit exceeds its estimated fair value, Step 2 is performed to determine if an impairment of goodwill is required. The fair value of the reporting units is estimated using discounted cash flow methodologies, as well as considering third party market value indicators. Goodwill impairment is measured by the excess of the carrying amount of the reporting unit’s goodwill over its implied fair value. Calculating the fair value of the reporting units, and allocating the estimated fair value to all of the tangible assets, intangible assets and liabilities, requires significant estimates and assumptions by management. Should the estimates and assumptions regarding the fair value of the reporting units prove to be incorrect, the Company may be required to record impairments to its goodwill in future periods and such impairments could be material. The Company has the option to perform a qualitative assessment to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. However, the Company may elect to perform the two-step quantitative goodwill impairment test even if no indications of a potential impairment exist. For its reporting unit with zero or negative carrying amount, the Company performs Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining whether it is more likely than not that goodwill impairment exists, the Company considers whether there are any adverse qualitative factors indicating that impairment may exist.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities The Company records its derivatives instruments at their respective fair values. The accounting for changes in the fair value (that is, gains or losses) of a derivative instrument is dependent upon whether the derivative has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship. The Company does not designate its derivative instruments to qualify for hedge accounting, accordingly the instruments are recorded at fair value as a current asset or liability and any changes in fair value are recorded in the consolidated statements of income.
Advertising Expense	Advertising Expense Cost of advertising is charged to selling, general and administrative expenses in the period in which it is incurred. In fiscal 2015, fiscal 2014 and fiscal 2013, advertising expense was $16.5 million, $17.2 million and $13.1 million, respectively.
Research and Development Costs	Research and Development Costs Costs for research and development are charged to expense as incurred. Research and development costs were incurred by Fabrix.
Capitalized Internal Use Software Costs	Capitalized Internal Use Software Costs The Company capitalizes the cost of internal-use software that has a useful life in excess of one year. These costs consist of payments made to third parties and the salaries of employees working on such software development. Subsequent additions, modifications or upgrades to internal-use software are capitalized only to the extent that they allow the software to perform a task it previously did not perform. Software maintenance and training costs are expensed in the period in which they are incurred. Capitalized internal use software costs are amortized on a straight-line basis over their estimated useful lives. Amortization expense related to such capitalized software in fiscal 2015, fiscal 2014 and fiscal 2013 was $11.4 million, $8.8 million and $7.3 million, respectively. Unamortized capitalized internal use software costs at July 31, 2015 and 2014 were $18.8 million and $15.1 million, respectively.
Repairs and Maintenance	Repairs and Maintenance The Company charges the cost of repairs and maintenance, including the cost of replacing minor items not constituting substantial betterment, to selling, general and administrative expenses as these costs are incurred.
Foreign Currency Translation	Foreign Currency Translation Assets and liabilities of foreign subsidiaries denominated in foreign currencies are translated to U.S. Dollars at end-of-period rates of exchange, and their monthly results of operations are translated to U.S. Dollars at the average rates of exchange for that month. Gains or losses resulting from such foreign currency translations are recorded in “Accumulated other comprehensive income” in the accompanying consolidated balance sheets. Foreign currency transaction gains and losses are reported in “Other (expense) income, net” in the accompanying consolidated statements of income.
Income Taxes	Income Taxes The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the period in which related temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in its assessment of a valuation allowance. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date of such change. The Company uses a two-step approach for recognizing and measuring tax benefits taken or expected to be taken in a tax return. The Company determines whether it is more-likely-than-not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. In evaluating whether a tax position has met the more-likely-than-not recognition threshold, the Company presumes that the position will be examined by the appropriate taxing authority that has full knowledge of all relevant information. Tax positions that meet the more-likely-than-not recognition threshold are measured to determine the amount of tax benefit to recognize in the financial statements. The tax position is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Differences between tax positions taken in a tax return and amounts recognized in the financial statements will generally result in one or more of the following: an increase in a liability for income taxes payable, a reduction of an income tax refund receivable, a reduction in a deferred tax asset, or an increase in a deferred tax liability. The Company classifies interest and penalties on income taxes as a component of income tax expense.
Contingencies	Contingencies The Company accrues for loss contingencies when both (a) information available prior to issuance of the financial statements indicates that it is probable that a liability had been incurred at the date of the financial statements and (b) the amount of loss can reasonably be estimated. When the Company accrues for loss contingencies and the reasonable estimate of the loss is within a range, the Company records its best estimate within the range. When no amount within the range is a better estimate than any other amount, the Company accrues the minimum amount in the range. The Company discloses an estimated possible loss or a range of loss when it is at least reasonably possible that a loss may have been incurred.
Earnings Per Share	Earnings Per Share Basic earnings per share is computed by dividing net income attributable to all classes of common stockholders of the Company by the weighted average number of shares of all classes of common stock outstanding during the applicable period. Diluted earnings per share is determined in the same manner as basic earnings per share, except that the number of shares is increased to include restricted stock still subject to risk of forfeiture and to assume exercise of potentially dilutive stock options using the treasury stock method, unless the effect of such increase is anti-dilutive. The weighted-average number of shares used in the calculation of basic and diluted earnings per share attributable to the Company’s common stockholders consists of the following: Year ended July 31 2015 2014 2013 Basic weighted-average number of shares 22,903 22,009 20,876 Effect of dilutive securities: Stock options 23 92 9 Non-vested restricted Class B common stock 321 836 1,430 Diluted weighted-average number of shares 23,247 22,937 22,315 The following outstanding stock options were excluded from the calculation of diluted earnings per share because the exercise price of the stock option was greater than the average market price of the Company’s stock during the period: Year ended July 31 2015 2014 2013 Shares excluded from the calculation of diluted earnings per share 136 70 611
Stock-Based Compensation	Stock-Based Compensation The Company recognizes compensation expense for all of its grants of stock-based awards based on the estimated fair value on the grant date. Compensation cost for awards is recognized using the straight-line method over the vesting period. Stock-based compensation is included in selling, general and administrative expense.
Vulnerability Due to Certain Concentrations	Vulnerability Due to Certain Concentrations Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash, cash equivalents, restricted cash and cash equivalents, marketable securities, investments in hedge funds and trade accounts receivable. The Company holds cash and cash equivalents at several major financial institutions, which often exceed FDIC insurance limits. Historically, the Company has not experienced any losses due to such concentration of credit risk. The Company’s temporary cash investments policy is to limit the dollar amount of investments with any one financial institution and monitor the credit ratings of those institutions. While the Company may be exposed to credit losses due to the nonperformance of the holders of its deposits, the Company does not expect the settlement of these transactions to have a material effect on its results of operations, cash flows or financial condition. Concentration of credit risk with respect to trade accounts receivable is limited due to the large number of customers in various geographic regions and industry segments comprising the Company’s customer base. No single customer accounted for more than 10% of consolidated revenues in fiscal 2015, fiscal 2014 or fiscal 2013. However, the Company’s five largest customers collectively accounted for 11.2%, 12.0% and 10.0% of its consolidated revenues from continuing operations in fiscal 2015, fiscal 2014 and fiscal 2013, respectively. The Company’s customers with the five largest receivables balances collectively accounted for 24.1% and 22.1% of the consolidated gross trade accounts receivable at July 31, 2015 and 2014, respectively. This concentration of customers increases the Company’s risk associated with nonpayment by those customers. In an effort to reduce such risk, the Company performs ongoing credit evaluations of its significant retail, wholesale and cable telephony customers. In addition, the Company attempts to mitigate the credit risk related to specific wholesale termination customers by also buying services from the customer, in order to create an opportunity to offset its payables and receivables and reduce its net trade receivable exposure risk. When it is practical to do so, the Company will increase its purchases from wholesale termination customers with receivable balances that exceed the Company’s applicable payables in order to maximize the offset and reduce its credit risk.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The allowance for doubtful accounts reflects the Company’s best estimate of probable losses inherent in the accounts receivable balance. The allowance is determined based on known troubled accounts, historical experience and other currently available evidence. Doubtful accounts are written-off upon final determination that the trade accounts will not be collected. The change in the allowance for doubtful accounts is as follows: Year ended July 31 Balance at beginning of year Additions charged to costs and expenses Deductions Balance at end of year 2015 Reserves deducted from accounts receivable: Allowance for doubtful accounts $ 11,507 $ 97 $ (5,959 ) $ 5,645 2014 Reserves deducted from accounts receivable: Allowance for doubtful accounts $ 13,079 $ 500 $ (2,072 ) $ 11,507 2013 Reserves deducted from accounts receivable: Allowance for doubtful accounts $ 13,044 $ 2,743 $ (2,708 ) $ 13,079 (1) Primarily uncollectible accounts written off, net of recoveries.
Fair Value Measurements	Fair Value Measurements Fair value of financial and non-financial assets and liabilities is defined as an exit price, which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The three-tier hierarchy for inputs used to measure fair value, which prioritizes the inputs to valuation techniques used to measure fair value, is as follows: Level 1 – quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 – quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 – unobservable inputs based on the Company’s assumptions used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy.
Recently Issued Accounting Standard Not Yet Adopted	Recently Issued Accounting Standard Not Yet Adopted In May 2014, the Financial Accounting Standards Board and the International Accounting Standards Board jointly issued a comprehensive new revenue recognition standard that will supersede most of the current revenue recognition guidance under U.S. GAAP and International Financial Reporting Standards (“IFRS”). The goals of the revenue recognition project were to clarify and converge the revenue recognition principles under U.S. GAAP and IFRS and to develop guidance that would streamline and enhance revenue recognition requirements. The Company will adopt this standard on August 1, 2018. Entities have the option of using either a full retrospective or modified retrospective approach for the adoption of the standard. The Company is evaluating the impact that the standard will have on its consolidated financial statements.
