Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	NOTE 5: FAIR VALUE MEASUREMENT FASB ASC No. 820, “Fair Value Measurements and Disclosures” defines fair value, establishes a framework for measuring fair value. Fair value is an exit price, representing the amount that would be received for selling an asset or paid for the transfer of a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. A three-tier fair value hierarchy is established as a basis for considering such assumptions and for inputs used in the valuation methodologies in measuring fair value: Level I Unadjusted quoted prices in active markets that are accessible on the measurement date for identical, unrestricted assets or liabilities; Level II Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level III Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity). The Company measures its marketable securities and foreign currency derivative contracts at fair value. Marketable securities and foreign currency derivative contracts are classified within Level II as the valuation inputs are based on quoted prices and market observable data of similar instruments. The table below sets forth the Company’s assets and liabilities measured at fair value by level within the fair value hierarchy. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
COMMON STOCK AND STOCK-BASED COMPENSATION PLANS	NOTE 8: COMMON STOCK AND STOCK-BASED COMPENSATION PLANS The Company grants stock options and stock appreciation rights (“SARs”) capped with a ceiling to employees and stock options to non-employee directors of the Company and its subsidiaries and provides the right to purchase common stock pursuant to the Company’s 2002 employee stock purchase plan to employees of the Company and its subsidiaries. The SAR unit confers the holder the right to stock appreciation over a preset price of the Company’s common stock during a specified period of time. When the unit is exercised, the appreciation amount is paid through the issuance of shares of the Company’s common stock. The ceiling limits the maximum income for each SAR unit. SARs are considered an equity instrument as it is a net share settled award capped with a ceiling (400% for SAR grants). The options and SARs granted under the Company’s stock incentive plans have been granted at the fair market value of the Company’s common stock on the grant date. Options and SARs granted to employees under stock incentive plans vest at a rate of 25% of the shares underlying the option after one year and the remaining shares vest in equal portions over the following 36 months, such that all shares are vested after four years. Options granted to non-employee directors vest 25% of the shares underlying the option on each anniversary of the option grant. A summary of the Company’s stock option and SARs activities and related information for the six months ended June 30, 2016, are as follows: Number of Weighted Weighted Outstanding as of December 31, 2015 2,406,455 $ 18.15 Granted — — Exercised (520,059 ) 14.74 Forfeited or expired (28,300 ) 17.83 Outstanding as of June 30, 2016 (2) 1,858,096 $ 19.11 4.3 $ 15,461,017 Exercisable as of June 30, 2016 (3) 1,312,950 $ 19.96 3.7 $ 9,944,437 (1) The SAR units are convertible for a maximum number of shares of the Company’s common stock equal to 75% of the SAR units subject to the grant. (2) Due to the ceiling imposed on the SAR grants, the outstanding amount equals a maximum of 1,639,795 shares of the Company’s common stock issuable upon exercise. (3) Due to the ceiling imposed on the SAR grants, the exercisable amount equals a maximum of 1,192,123 shares of the Company’s common stock issuable upon exercise. As of June 30, 2016, there was $1,218 of unrecognized compensation expense related to unvested stock options and SARs. This amount is expected to be recognized over a weighted-average period of 1.3 years. To the extent the actual forfeiture rate is different from what the Company has estimated, equity-based compensation related to these awards will be different from the Company’s expectations. Starting in the second quarter of 2015, the Company granted to employees, including executive officers, and non-employee directors, restricted stock units (“RSUs”) under the Company’s 2011 Stock Incentive Plan. A RSU award is an agreement to issue shares of the Company’s common stock at the time the award or a portion thereof vests. RSUs granted to employees generally vest in three equal annual installments starting on the first anniversary of the grant date. RSUs granted to non-employee directors generally vest in full on the first anniversary of the grant date. The fair value of each RSU is the market value as determined by the closing price of the common stock on the day of grant. The Company recognizes compensation expenses for the value of its RSU awards, based on the straight-line method over the requisite service period of each of the awards, net of estimated forfeitures. A summary of the Company’s RSU activities and related information for the six months ended June 30, 2016, are as follows: Number of Weighted Average Unvested as of December 31, 2015 234,000 $ 19.89 Granted 338,100 20.79 Vested (64,640 ) 19.83 Forfeited or expired (3,967 ) 20.25 Unvested as of June 30, 2016 503,493 $ 20.50 Expected to vest after June 30, 2016 463,214 $ 20.49 As of June 30, 2016, there was $8,128 of unrecognized compensation expense related to unvested RSUs. This amount is expected to be recognized over a weighted-average period of 1.7 years.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES AND HEDGING ACTIVITIES	NOTE 9: DERIVATIVES AND HEDGING ACTIVITIES The Company follows the requirements of FASB ASC No. 815,” Derivatives and Hedging” which requires companies to recognize all of their derivative instruments as either assets or liabilities in the statement of financial position at fair value. The accounting for changes in fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging transaction and further, on the type of hedging transaction. For those derivative instruments that are designated and qualify as hedging instruments, a company must designate the hedging instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge, or a hedge of a net investment in a foreign operation. Due to the Company’s global operations, it is exposed to foreign currency exchange rate fluctuations in the normal course of its business. The Company’s treasury policy allows it to offset the risks associated with the effects of certain foreign currency exposures through the purchase of foreign exchange forward or option contracts (“Hedging Contracts”). The policy, however, prohibits the Company from speculating on such Hedging Contracts for profit. To protect against the increase in value of forecasted foreign currency cash flow resulting from salaries paid in currencies other than the U.S. dollar during the year, the Company instituted a foreign currency cash flow hedging program. The Company hedges portions of the anticipated payroll of its non-U.S. employees denominated in the currencies other than the U.S. dollar for a period of one to twelve months with Hedging Contracts. Accordingly, when the dollar strengthens against the foreign currencies, the decline in present value of future foreign currency expenses is offset by losses in the fair value of the Hedging Contracts. Conversely, when the dollar weakens, the increase in the present value of future foreign currency expenses is offset by gains in the fair value of the Hedging Contracts. These Hedging Contracts are designated as cash flow hedges. For derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Any gain or loss on a derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item is recognized in current earnings during the period of change. As of June 30, 2016 and December 31, 2015, the notional principal amount of the Hedging Contracts to sell U.S. dollars held by the Company was $6,300 and $3,200, respectively. The fair value of the Company’s outstanding derivative instruments is as follows: June 30, December 31, 2016 2015 (Unaudited) (Audited) Derivative assets: Derivatives designated as cash flow hedging instruments: Foreign exchange option contracts $ 25 $ — Foreign exchange forward contracts 19 9 Total $ 44 $ 9 Derivative liabilities Derivatives designated as cash flow hedging instruments: Foreign exchange forward contracts $ 14 $ — The Company recorded the fair value of derivative assets in “prepaid expenses and other current assets” and the fair value of derivative liabilities in “accrued expenses and other payables” on the Company’s interim condensed consolidated balance sheets. The increase (decrease) in unrealized gains (losses) recognized in “accumulated other comprehensive income (loss)” on derivatives, before tax effect, is as follows: Six months ended Three months ended 2016 2015 2016 2015 (unaudited) (unaudited) (unaudited) (unaudited) Derivatives designated as cash flow hedging instruments: Foreign exchange option contracts $ 74 $ 212 $ (48 ) $ 288 Foreign exchange forward contracts 69 63 (44 ) 97 $ 143 $ 275 $ (92 ) $ 385 The net (gains) losses reclassified from “accumulated other comprehensive income (loss)” into income are as follows: Six months ended Three months ended 2016 2015 2016 2015 (unaudited) (unaudited) (unaudited) (unaudited) Derivatives designated as cash flow hedging instruments: Foreign exchange option contracts $ (49 ) $ 59 $ (49 ) $ 8 Foreign exchange forward contracts (73 ) (58 ) (48 ) (80 ) $ (122 ) $ 1 $ (97 ) $ (72 ) The Company recorded in cost of revenues and operating expenses a net gain of $97 and $122 during the three and six months ended June 30, 2016, respectively, and a net gain of $72 and a net loss of $1 for the comparable periods of 2015, related to its Hedging Contracts.

SHARE REPURCHASE PROGRAM	NOTE 11: SHARE REPURCHASE PROGRAM The Company did not repurchase shares of common stock during the second quarter of 2016. During the second quarter of 2015, the Company repurchased 176,117 shares of common stock at an average purchase price of $19.46 per share for an aggregate purchase price of $3,426. During the first six months ended June 30, 2016, the Company repurchased 180,013 shares of common stock at an average purchase price of $18.98 per share for an aggregate purchase price of $3,417. During the first six months ended June 30, 2015, the Company repurchased 270,020 shares of common stock at an average purchase price of $19.79 per share for an aggregate purchase price of $5,343. As of June 30, 2016, 311,056 shares of common stock remained available for repurchase pursuant to the Company’s share repurchase program. The repurchases of common stock are accounted for as treasury stock, and result in a reduction of stockholders’ equity. When treasury shares are reissued, the Company accounts for the reissuance in accordance with FASB ASC No. 505-30, “Treasury Stock” and charges the excess of the repurchase cost over issuance price using the weighted average method to retained earnings. The purchase cost is calculated based on the specific identified method. In the case where the repurchase cost over issuance price using the weighted average method is lower than the issuance price, the Company credits the difference to additional paid-in capital.

Accounting Changes and Error Corrections [Abstract]
IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS NOT YET ADOPTED	NOTE 12: IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS NOT YET ADOPTED In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers.” Under this guidance, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The updated standard will replace most existing revenue recognition guidance under GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. As currently issued and amended, ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, although early adoption is permitted for annual reporting periods beginning after December 15, 2016. The Company is currently evaluating the effect that the updated standard will have on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” which will replace the existing guidance in ASC 840, “Leases.” The updated standard aims to increase transparency and comparability among organizations by requiring lessees to recognize lease assets and lease liabilities on the balance sheet and requiring disclosure of key information about leasing arrangements. This ASU is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods; early adoption is permitted and modified retrospective application is required. The Company is in the process of evaluating this guidance to determine the impact it will have on its financial statements and related disclosures. In March 2016, the FASB issued ASU 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net),” which clarifies the implementation guidance on principal versus agent considerations under the new revenue recognition standard, ASU 2014-09. In April 2016, the FASB issued ASU 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing,” which clarifies the implementation guidance on identifying promised goods or services from a principal and agent perspective. The Company will adopt the standard effective January 1, 2018. The Company is continuing to evaluate the full effect that ASU 2014-09 and related subsequent updates will have on its consolidated financial statements and related disclosures. In March 2016, the FASB issued ASU 2016-09, “Compensation-Stock Compensation,” which simplifies several aspects of the accounting for share-based payments, including immediate recognition of all excess tax benefits and deficiencies in the income statement, changing the threshold to qualify for equity classification up to the employees’ maximum statutory tax rates, allowing an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures as they occur, and clarifying the classification on the statement of cash flows for the excess tax benefit and employee taxes paid when an employer withholds shares for tax-withholding purposes. The Company is evaluating the full effect that ASU 2016-09 will have on its consolidated financial statements and related disclosures and will adopt the standard effective January 1, 2017. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606). ASU 2016-10 amends ASC 606, Revenue from Contracts with Customers, to clarify two aspects of ASC 606, identifying performance obligations and the licensing implementation guidance, while retaining the related principles of those areas. The amendments in ASU 2016-10 do not change the core principle of the guidance in ASC 606. The amendments in ASU No. 2016-10 affect the guidance in ASU 2014-09, Revenue from Contracts with Customers (Topic 606) , In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606). ASU 2016-12 amends ASC 606 to address certain issues in the guidance on assessing collectability, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition. The amendments in ASU 2016-12 do not change the core principle of the guidance in ASC 606. The amendments in ASU No. 2016-12 affect the guidance in ASU 2014-09, Revenue from Contracts with Customers (Topic 606) ,
