| Management believes that as of September 30, 2014, the unrealized losses in the Company’s investments in all types of marketable securities were temporary and no impairment loss was realized in the Company’s condensed consolidated statement of income. | |||||||||||||||||||||||||
| Marketable securities are periodically reviewed for impairment. If management concludes that any marketable security is impaired, management determines whether such impairment is other-than-temporary. Factors considered in making such a determination include the duration and severity of the impairment, the reason for the decline in value and the potential recovery period, and the Company's intent to sell, or whether it is more likely than not that the Company will be required to sell the marketable security before recovery of cost basis. If any impairment is considered other-than-temporary, the marketable security is written down to its fair value through a corresponding charge to financial income, net. | |||||||||||||||||||||||||
| The total fair value of marketable securities with outstanding unrealized losses as of September 30, 2014 amounted to $68,921. Of the $721 unrealized losses outstanding as of September 30, 2014 and presented in the table above, a portion of which in the amount of $149, was related to marketable securities that were in a loss position for more than 12 months and the remaining portion in the amount of $572 was related to marketable securities that were in a loss position for less than 12 months. | |||||||||||||||||||||||||
| Proceeds from maturity of available-for-sale marketable securities during the nine months ended September 30, 2014 and 2013 were $9,896 and $15,180, respectively. Proceeds from sales of available-for-sale marketable securities during the nine months ended September 30, 2014 and 2013 were $40,821 and $27,814, respectively. Net realized gains from the sale of available-for sale marketable securities for the nine months ended September 30, 2014 and 2013 were $62 and $726, respectively.

| The Company sells its products primarily through distributors and directly to original equipment manufacturers (OEMs) and original design manufacturers (ODMs) who incorporate the Company’s products into consumer products. The Company’s future performance will depend, in part, on the continued success of its distributors in marketing and selling its products. The loss of the Company’s distributors and the Company’s inability to obtain satisfactory replacements in a timely manner may harm the Company’s sales and results of operations. In addition, the Company expects that a limited number of customers, varying in identity from period-to-period, will account for a substantial portion of its revenues in any period. The loss of, or reduced demand for products from, any of the Company’s major customers could have a material adverse effect on the Company’s business, financial condition and results of operations. | |
| Sales to Hong Kong-based VTech Holdings Ltd. (“VTech”) represented 34% and 35% of the Company’s total revenues for the three months ended September 30, 2014 and 2013, respectively. Sales to VTech represented 36% of the Company’s total revenues for both the nine months ended September 30, 2014 and 2013. | |
| Revenues derived from sales through one distributor, Tomen Electronics Corporation (“Tomen Electronics”), accounted for 22% and 24% of the Company’s total revenues for the three months ended September 30, 2014 and 2013, respectively. Tomen Electronics accounted for 21% and 18% of the Company's total revenues for the nine months ended September 30, 2014 and 2013, respectively. The Japanese market and the OEMs that operate in that market are among the largest suppliers in the world with significant market share in the U.S. market for residential wireless products. Tomen Electronics sells the Company’s products to a limited number of customers. One customer, Panasonic Communications Co., Ltd. (“Panasonic”), has continually accounted for a majority of the sales of Tomen Electronics.

| NOTE g—DERIVATIVE INSTRUMENTS | ||||||||||||||||||
| The Company accounts for derivative instruments in accordance with FASB. ASC No. 815 “Derivatives and Hedging” (“ASC 815”). 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 contracts and put options (collectively, “hedging contracts”). The policy, however, prohibits the Company from speculating on hedging contracts for profit. | ||||||||||||||||||
| To protect against the increase in value of forecasted foreign currency cash flows resulting from salary and lease payments of its Israeli facilities denominated in the Israeli currency, the New Israeli Shekels (“NIS”), during the year, the Company instituted a foreign currency cash flow hedging program. The Company hedges portions of the anticipated payroll and lease payments denominated in NIS 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 cash flows is offset by gains in the fair value of the hedging contracts. These hedging contracts are designated as cash flow hedges, as defined by ASC 815, and are all effective hedges of these expenses. | ||||||||||||||||||
| In accordance with ASC 815, 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 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 September 30, 2014, the Company had outstanding foreign exchange forward contracts in the amount of $3,450 and outstanding option contracts in the amount of $11,725. These hedging contracts do not contain any credit-risk-related contingency features. See Note K for information on the fair value of these hedging contracts. | ||||||||||||||||||
| The fair value of derivative assets and derivative liabilities were $32 and $456, respectively, at September 30, 2014. The Company recorded a net amount of $424 in accrued expenses and other accounts payable in the condensed consolidated balance sheets at September 30, 2014. | ||||||||||||||||||
| The amount recorded as expense in research and development expenses, sales and marketing expenses and general and administrative expenses in the condensed consolidated statements of income for the nine months ended September 30, 2014 that resulted from the above referenced hedging transactions was $72, $7 and $13, respectively. The amount recorded as expense in research and development expenses, sales and marketing expenses and general and administrative expenses in the condensed consolidated statements of income for the three months ended September 30, 2014 that resulted from the above referenced hedging transactions was $76, $8 and $13, respectively. | ||||||||||||||||||

As of September 30, 2014, 1,203,601 shares of common stock remained authorized for repurchase under the Company's board-authorized share repurchase program. | |
| 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 Accounting Principles Board Opinion No. 6, “Status of Accounting Research Bulletins” and charges the excess of the repurchase cost over issuance price using the weighted average method to accumulated deficit. 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. | |
| During the first nine months of 2014, the Company issued approximately 605,000 shares of common stock out of treasury stock to employees who exercised their stock options, SARs or RSUs, or purchased shares from the Company’s 1993 Employee Stock Purchase Plan. |

| Description of segments: | |||||||||||||||||
| The Company operates under three reportable segments. | |||||||||||||||||
| The Company's segment information has been prepared in accordance with ASC 280, "Segment Reporting." Operating segments are defined as components of an enterprise engaging in business activities about which separate financial information is available that is evaluated regularly by the Company's chief operating decision-maker (“CODM”) in deciding how to allocate resources and assess performance. The Company's CODM is its Chief Executive Officer, who evaluates the Company's performance and allocates resources based on segment revenues and operating income. | |||||||||||||||||
| The Company's operating segments are as follows: Home, Office and Mobile. The classification of the Company’s business segments is based on a number of factors that management uses to evaluate, view and run its business operations, which include, but are not limited to, customer base, homogeneity of products and technology. | |||||||||||||||||
| A description of the types of products provided by each business segment is as follows: | |||||||||||||||||
| Home - Wireless chipset solutions for converged communication at home. Such solutions include integrated circuits targeted for cordless phones sold in retail or supplied by telecommunication service providers, residential gateway devices supplied by telecommunication service providers which integrate the DECT/CAT-iq functionality and also address home automation applications, as well as fixed-mobile convergence solutions. | |||||||||||||||||
| Office - Comprehensive solution for Voice-over-IP (VOIP) office products, including office solutions that offer businesses of all size low-cost VOIP terminals with converged voice and data applications. | |||||||||||||||||
| Mobile - Products for the mobile market that provides voice enhancement and far-end noise elimination targeted for mobile phone and mobile headsets. | |||||||||||||||||
| Segment data: | |||||||||||||||||
| The Company derives the results of its business segments directly from its internal management reporting system and by using certain allocation methods. The accounting policies the Company uses to derive business segment results are substantially the same as those the Company uses for consolidation of its financial statements. The CODM measures the performance of each business segment based on several metrics, including earnings from operations. The CODM uses these results, in part, to evaluate the performance of, and to assign resources to, each of the business segments. The Company does not allocate to its business segments certain operating expenses, which it manages separately at the corporate level. These unallocated costs include primarily restructuring charges, amortization of purchased intangible assets, equity-based compensation expenses, proxy contest related expenses incurred during the second quarter of 2013 and certain corporate governance costs. | |||||||||||||||||

| NOTE O – GOVERNMENT GRANTS | |
| Government grants received by the Company’s Israeli subsidiary relating to categories of operating expenditures are credited to the consolidated statements of income during the period in which the expenditure to which they relate is charged. Royalty and non-royalty-bearing grants from the Israeli Office of the Chief Scientist ("OCS") for funding certain approved research and development projects are recognized at the time when the Company’s Israeli subsidiary is entitled to such grants, on the basis of the related costs incurred, and are included as a deduction from research and development expenses, net. | |
| The Company recorded grants in the amount of $460 and $1,200 for the three months ended September 30, 2014 and 2013, respectively. | |
| The Company recorded grants in the amount of $2,500 and $1,260 for the nine months ended September 30, 2014 and 2013, respectively. | |
| The Company’s Israeli subsidiary is obligated to pay royalties amounting to 5% of the sales of certain products the development of which received grants from the OCS in previous years. The obligation to pay these royalties is contingent on actual sales of such products. Grants received from the OCS may become repayable if certain criteria under the grants are not met. In addition, the Company may be required to repay up to six times the amount of the grants if the technology that was developed using those grants is sold directly or indirectly. |
