NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 — THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Company

Mellanox Technologies, Ltd. (the “Company” or “Mellanox”) was incorporated in Israel and commenced operations in March 1999. Mellanox is a supplier of high-performance interconnect products for computing, storage and communications applications.

Principles of presentation

The unaudited condensed consolidated financial statements include the Company’s accounts as well as those of its wholly owned subsidiaries after the elimination of all intercompany balances and transactions.

The unaudited condensed consolidated financial statements included in this quarterly report on Form 10-Q have been prepared by the Company without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The year-end unaudited condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures contained in this quarterly report comply with the requirements of Section 13(a) of the Securities Exchange Act of 1934, as amended, for a quarterly report on Form 10-Q and are adequate to make the information presented not misleading. The unaudited condensed consolidated financial statements included herein reflect all adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods presented. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014, filed with the SEC on March 2, 2015. The results of operations for the three months ended March 31, 2015 are not necessarily indicative of the results to be anticipated for the entire year ending December 31, 2015 or thereafter.

Certain prior year amounts have been reclassified to conform to 2015 presentation. These changes and reclassifications did not impact net or comprehensive income.

Revision to Prior Period Financial Statements

During the year ended December 31, 2014, the Company became aware of and corrected immaterial errors primarily related to the accounting for liabilities for warranty, certain purchase orders, distributor price adjustment claims and purchase price allocation for the acquisitions of Kotura and IPtronics. The Company evaluated these errors and determined that the impact of the errors was not material to its results of operations, financial position or cash flows in previously issued financial statements. The Company has retrospectively revised financial information for all prior periods presented to reflect this correction. The impact of this revision for periods presented within this quarterly report on Form 10-Q are shown in the tables below:

Risks and uncertainties

The Company is subject to all of the risks inherent in a company which operates in the dynamic and competitive semiconductor industry. Significant changes in any of the following areas could have a materially adverse impact on the Company’s financial position and results of operations: unpredictable volume or timing of customer orders; ordered product mix; the sales outlook and purchasing patterns of the Company’s customers based on consumer demands and general economic conditions; loss of one or more of the Company’s customers; decreases in the average selling prices of products or increases in the average cost of finished goods; the availability, pricing and timeliness of delivery of components used in the Company’s products; reliance on a limited number of subcontractors to manufacture, assemble, package and production test the Company’s products; the Company’s ability to successfully develop, introduce and sell new or enhanced products in a timely manner; product obsolescence and the Company’s ability to manage product transitions; the timing of announcements or introductions of new products by the Company’s competitors; and the Company’s ability to successfully integrate acquired businesses.

Use of estimates

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the dates of the financial statements and the reported amounts of net revenue and expenses in the reporting periods. The Company regularly evaluates estimates and assumptions related to revenue recognition, allowances for doubtful accounts, sales returns and allowances, investment valuation, warranty reserves, inventory reserves, share-based compensation expense, long-term asset valuations, goodwill and purchased intangible asset valuation, hedge effectiveness, deferred income tax asset valuation, uncertain tax positions, litigation and other loss contingencies. These estimates and assumptions are based on current facts, historical experience and various other factors that the Company believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of revenue, costs and expenses that are not readily apparent from other sources. The actual results that the Company experiences may differ materially and adversely from the Company’s original estimates. To the extent there are material differences between the estimates and actual results, the Company’s future results of operations will be affected.

Significant accounting policies

There have been no changes in the Company’s significant accounting policies that were disclosed in its Annual Report on Form 10-K for the fiscal year ended December 31, 2014. See our Annual Report on Form 10-K for the year ended December 31, 2014, filed with the SEC on March 2, 2015, for a discussion of significant accounting policies and estimates.

	Three Months Ended March 31,
	2015		2014
Net income (loss)	$	10,496	$	(10,980	)
Basic and diluted shares:
Weighted average ordinary shares outstanding used to compute basic net income (loss) per share	45,691		44,276
Dilutive effect of employee share option and purchase plans	1,343		—
Shares used to compute diluted net income (loss) per share	47,034		44,276
Net income (loss) per share — basic	$	0.23	$	(0.25	)
Net income (loss) per share — diluted	$	0.22	$	(0.25	)

9

The Company excluded 592,035 and 895,280 outstanding shares for the three months ended March 31, 2015 and March 31, 2014, respectively, from the computation of diluted net income (loss) per ordinary share, because including these outstanding shares would have had an anti-dilutive effect.

Recent accounting pronouncements

On May 28, 2014, the FASB issued new accounting guidance related to revenue recognition. This new standard will replace all current GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. This guidance will be effective for the Company for the fiscal year beginning January 1, 2017 and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. Early adoption is not permitted. The Company is currently evaluating the impact of adopting this new accounting standard on its consolidated financial statements.

In August 2014, the FASB issued new guidance related to the disclosures around going concern. The new standard provides guidance around management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The new standard will be effective for the Company for the fiscal year ending December 31, 2016. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company’s financial statements.

NOTE 3 — FAIR VALUE MEASUREMENTS:

Fair value hierarchy

The Company measures its financial instruments at fair value. The Company’s cash equivalents are classified within Level 1. Cash equivalents are valued primarily using quoted market prices utilizing market observable inputs. The Company’s investments in debt securities and certificates of deposits are classified within Level 2 as the market inputs to value these instruments consist of market yields, reported trades and broker/dealer quotes. In addition, foreign currency contracts are classified within Level 2 as the valuation inputs are based on quoted prices and market observable data of similar instruments. The Level 3 valuation inputs include the Company’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The inputs are unobservable in the market and significant to the instrument’s valuation. As of March 31, 2015 and December 31, 2014, the Company did not have any financial instruments valued based on Level 3 valuations.

The following table represents the fair value hierarchy of the Company’s financial assets and liabilities measured at fair value as of March 31, 2015.

Legal proceedings

The Company is currently involved in various legal proceedings. Unless otherwise noted below, during the periods presented the Company did not record any accrual for loss contingencies associated with such legal proceedings, determined that an unfavorable outcome is probable or reasonably possible, or determine that the amount or range of any possible loss is reasonably estimable. The Company is engaged in other legal actions not described below arising in the ordinary course of its business and, while there can be no assurance, it believes that the ultimate outcome of these actions will not have a material adverse effect on its operating results, liquidity or financial position.

Pending legal proceedings as of March 31, 2015 were as follows:

Avago Technologies Fiber (IP) Singapore Pte. Ltd.vs. IPtronics, Inc. and IPtronics A/S

On September 29, 2010, Avago Technologies Fiber (IP) Singapore Pte. Ltd. (“Avago IP”) filed a complaint for patent infringement against IPtronics, Inc. and IPtronics A/S (now Mellanox Technologies Denmark Aps) (collectively, “IPtronics”) now pending  in the United States District Court, Northern District of California, San Jose Division (Case No.: 5:10-cv-02863 EJD), asserting infringement of the 456 patent and U.S. Patent No. 5,359,447. On September 11, 2012, Avago IP along with additional subsidiaries of Avago Technologies Limited (collectively, “Avago”) filed a second amended and supplemental complaint against the IPtronics adding allegations that IPtronics engaged in violations of the Lanham Act, Section 43 (A); misappropriated Avago’s trade secrets; engaged in unfair competition against Avago; intentionally interfered with Avago’s contractual relations; and were unjustly enriched by and through the conduct complained of by Avago. A motion to file a third amended complaint was filed but never granted.

Avago’s motion to file a Fourth Amended and Supplemental Complaint (the “Complaint”) to add the Company and a new claim for interference with prospective economic advantage against IPtronics was granted. The Company and IPtronics have answered the new complaint and the case is set for trial in May-June, 2016. IPtronics’ motion to add an antitrust counterclaim against Avago for pursuing a sham action was denied and, as explained below, that claim is being pursued in a separate action.

15

Pursuant to the Complaint, Avago seeks unspecified damages, treble damages, injunctive relief and any other relief deemed just and proper by the court. Neither the outcome of the proceeding nor the amount and range of potential damages or exposure associated with the proceeding can be assessed with certainty. In the event IPtronics is not successful in defending the Complaint, the Company could be forced to license technology from Avago and be prevented from importing, selling, offering for sale, advertising, soliciting, using and/or warehousing for distribution the allegedly infringing products. Based on currently available information, the Company believes that the resolution of this proceeding is not likely to have a material adverse effect on the Company’s business, financial position, results of operations or cash flows.

IPtronics Inc. and Mellanox Technologies Denmark ApS vs. Avago Technologies Inc., et al.

IPtronics has filed an antitrust Complaint in the United States District Court, Northern District of California, San Jose Division (Case No.: 5:14-cv-05647-BLF (PSG)), against the US and foreign Avago entities (collectively “Avago”) for pursuing what the Company believes to be a baseless ITC action against IPtronics. The Complaint seeks unspecified damages in an amount to compensate IPtronics for the damages resulting from the Avago Entities’ alleged illegal conduct. In response to the Complaint Avago filed a motion to dismiss which will be heard on June 11, 2015. No case schedule has been set.

Weinberger Case

On February 20, 2013, a request for approval of a class action was filed in the Economic Division of the District Court of Tel Aviv-Jaffa against Mellanox Technologies, Ltd., the Company’s President and CEO, former CFO, CFO and each of the members of the Company’s board of directors (the “Israeli Claim”). The Israeli Claim was filed by Mr. Avigdor Weinberger (the “Claimant”). The Israeli Claim alleges that the Company, the board members, the Company’s President and CEO, its former CFO and its current CFO are responsible for making misleading statements (or failing to disclose certain facts) and filings to the public, as a result of which the shares of the Company were allegedly traded at a higher price than their true value during a period commencing on April 19, 2012 and ending January 2, 2013 and, therefore, these parties are responsible for damages caused to the purchasers of the Company’s shares on the Tel Aviv Stock Exchange during this time. The Claimant seeks an award of compensation to the relevant shareholders for all damages caused to them, including attorney fees and Claimant’s fee and any other relief deemed just and proper by the court. On April 24, 2013, the Claimant and the Company filed a procedural agreement with the court to stay the Israeli Claim pending the completion of the In re Mellanox Technologies, Ltd. Securities Litigation disclosed herein. On April 24, 2013, the Israeli court approved this procedural agreement and stayed the Israeli proceedings.

On January 7, 2015 the plaintiff, with the consent of the Company, filed a request to withdraw the Israeli Claim (and related class action claim) against the Company and the Board (the “Withdrawal Petition”) after the plaintiff, in view of the decision to dismiss the U. S. Class Action (In re Mellanox Technologies, Ltd. Securities Litigation disclosed herein), reached the conclusion that it would be difficult for the plaintiff to prove the Israeli Claim and have the complaint approved as a class action. Neither the plaintiff nor its attorneys received or will receive any benefit in return for their withdrawal.

On January 8, 2015, the Israeli Court approved the Withdrawal Petition and dismissed the Israeli Claim.

Infinite Data Case

On February 19, 2013, Infinite Data LLC, a Delaware limited liability company (“Infinite Data”) and a non-practicing entity and exclusive licensee of U.S. patent number 5,790,530 (the “Patent”), filed suit against approximately 25 of the Company’s end users and direct customers of its InfiniBand products in the United States District Court in Delaware. All actions included the same allegation of infringement regarding the Patent and seek the payment of damages, costs, expenses and injunctive relief. Several of the end users and direct customers sued by Infinite Data tendered indemnification requests to the Company on the basis of existing contractual or asserted statutory obligations imposed on the Company to provide such indemnification. All of these cases were stayed pending the outcome of the declaratory judgment action filed by the Company (see below). Based on currently available information, the Company believes that the resolution of these proceedings is not likely to have a material adverse effect on the Company’s business, financial position, results of operations or cash flows.

In response to these filings and accusations of infringement by the Company’s products, on May 21, 2013, the Company filed a declaratory judgment complaint against Infinite Data asking for a declaration that the Patent is invalid and that the Company’s products do not infringe. On November 14, 2013, Infinite Data filed its answer denying that the Patent was invalid and counterclaimed that the Company’s products infringe. Pursuant to the Counterclaims, Infinite Data seeks unspecified damages, treble damages, injunctive relief and any other relief deemed just and proper by the court.

16

Infinite Data, Mellanox Technologies, Ltd. and Mellanox Technologies, Inc. each entered into settlement agreements in which Infinite Data agreed to dismiss Mellanox Technologies, Ltd., with no liability or payment made by Mellanox Technologies, Ltd. and to dismiss Mellanox Technologies, Inc. in exchange for a payment of $1.3M. The case against Mellanox Technologies, Ltd. was dismissed with prejudice on December 3, 2014 and the case against Mellanox Technologies, Inc. was dismissed with prejudice on January 5, 2015. In accordance with the terms of the settlement agreement, Infinite Data has dismissed with prejudice its complaints against all of Mellanox Technologies, Inc.’s direct and indirect customers except Ford, which dismissal is still pending.

NOTE 10 — INCOME TAXES:

As of March 31, 2015 and December 31, 2014, the Company had gross unrecognized tax benefits of $20.5 million and $18.0 million, respectively. It is the Company’s policy to classify accrued interest and penalties as part of the unrecognized tax benefits and record the expense in the provision for income taxes. As of March 31, 2015 and December 31, 2014, the amount of accrued interest and penalties totaled $1.0 million and $1.0 million, respectively. As of March 31, 2015, calendar years 2009 and thereafter are open and subject to potential examination in one or more jurisdictions. The Beneficiary Enterprise tax holiday associated with the Company’s Yokneam and Tel Aviv operations began in 2011. The tax holiday for the Company’s Yokneam operations will expire in 2020 and the Tax Holiday for the Company’s Tel-Aviv operations will expire between the years 2017 and 2020. The tax holiday has resulted in a cash tax savings of $6.1 million and $0.2 million in the three months ended March 31, 2015 and March 31, 2014 respectively, increasing diluted earnings per share by approximately $0.13 and $0.01 in the three months ended March 31, 2015 and March 31, 2014 respectively.

19

The Company’s effective tax rate is highly dependent upon the geographic distribution of its worldwide earnings or losses, tax regulations and tax holiday benefits in Israel, and the effectiveness of the Company’s tax planning strategies. The Company’s effective tax rates were 17.6% and (6.3%) for the three months ended March 31, 2015 and 2014, respectively. The difference between the Company’s effective tax rates and the 35% federal statutory rate resulted primarily from the tax holiday in Israel and foreign earnings taxed at rates lower than the federal statutory rates, partially offset by the accrual of unrecognized tax benefits, interest and penalties associated with unrecognized tax positions, non-tax-deductible expenses such as share-based compensation and losses generated from subsidiaries without tax benefit.

The application of income tax law is inherently complex. Laws and regulations in this area are voluminous and are often ambiguous, and the Company is required to make many subjective assumptions and judgments regarding its income tax exposures. In addition, interpretations of and guidance surrounding income tax laws and regulations are subject to change over time. Any changes in the Company’s subjective assumptions and judgments could materially affect amounts recognized in its consolidated balance sheets and statements of income.

The Company assesses its ability to recover its deferred tax assets on an ongoing basis. Significant management judgment is required in determining any valuation allowance recorded against deferred tax assets. In evaluating the ability to recover deferred tax assets, the Company considers available positive and negative evidence including its recent cumulative losses, its ability to carry-back losses against prior taxable income and its projected financial results. The Company also considers, commensurate with its objective verifiability, the forecast of future taxable income including the reversal of temporary differences and the implementation of feasible and prudent tax planning strategies. A valuation allowance may be recorded in the event it is deemed to be more-likely-than-not that the deferred tax asset cannot be realized.  Previously established valuation allowances may also be released in the event it is deemed to be more-likely-than-not that the deferred tax asset can be realized.  Any release of valuation allowance will be recorded as a tax benefit which will positively impact the Company’s operating results.  The Company believes, based on the quarterly assessment performed at March 31, 2015, that it is possible that a valuation allowance may be released in the future if sustained levels of profitability are achieved.

Overview

We are a fabless semiconductor company that designs, manufactures and sells high-performance interconnect products and solutions primarily based on the InfiniBand and Ethernet standards. Our products facilitate efficient data transmission between servers, storage systems, communications infrastructure equipment and other embedded systems. We operate our business globally and offer products to customers at various levels of integration. The products we offer include integrated circuits (“ICs”), adapter cards, switch systems, cables, modules, software, services and accessories as an integral part of a total end-to-end networking solution focused on computing, storage and communication applications used in multiple markets, including high-performance computing (“HPC”), Web 2.0, storage, financial services, enterprise data center (“EDC”) and cloud. Our adapters and switch ICs provide per port bandwidth up to 10Gb/s, 40Gb/s and 56Gb/s Ethernet, and 10Gb/s (“Single Data Rate” or “SDR”), 20Gb/s (“Double Data Rate” or “DDR”), 40Gb/s (“Quad Data Rate” or “QDR”), 56Gb/s (“Fourteen Data Rate” or “FDR”) and 100Gb/s (“Enhanced Data Rate” or “EDR”) InfiniBand. These solutions are intended to increase performance, application productivity and improve return on investment. Through the successful development and implementation of multiple generations of our products, we have established significant expertise and competitive advantages.

We are one of the pioneers of InfiniBand, an industry-standard architecture for high-performance interconnects. We believe InfiniBand interconnect solutions deliver industry-leading performance, efficiency and scalability for clustered computing and storage systems that incorporate our products. In addition to supporting InfiniBand, our products also support industry-standard Ethernet transmission protocols providing unique product differentiation and connectivity flexibility. Our products serve as building blocks for creating reliable and scalable InfiniBand and Ethernet solutions with leading performance. We also believe that we are one of the early suppliers of 25/50/100Gb/s Ethernet adapters and 40Gb/s Ethernet switches to the market, and the only end-to-end 40 and 56Gb/s Ethernet supplier on the market today, which provides us with the opportunity to gain additional share in the Ethernet market as users upgrade from one or 10Gb/s directly to 25/40/50 or 56Gb/s.

As a leader in developing multiple generations of high-speed interconnect solutions, we have established strong relationships with our customers. Our products are incorporated in servers and associated networking solutions produced by server vendors. We supply our products to leading storage and communications infrastructure equipment vendors. Additionally, our products are used as embedded solutions.

Revenues. We derive revenues from sales of our ICs, boards, switch systems, cables, modules, software, accessories and other product groups. Our sales have historically been made on the basis of purchase orders rather than long-term agreements. Revenues for the three months ended March 31, 2015 were $146.7 million compared to $99.0 million for the three months ended March 31, 2014, representing an increase of approximately 48.2%. Our fiscal first quarter 2015 revenues are not necessarily indicative of future results.

21

Our products have broad adoption with multiple end customers across HPC, Web 2.0, cloud, EDC, financial services and storage markets, however, these markets are mainly served by leading server, storage and communications infrastructure OEMs. Therefore, we have derived a substantial portion of our revenues from a relatively small number of OEM customers. Sales to our top ten customers represented 60% and 61% of our total revenues for the three months ended March 31, 2015 and 2014, respectively. Sales to customers representing 10% or more of revenues accounted for 12% and 12% of our total revenues for the three months ended March 31, 2015 and 2014, respectively. The loss of one or more of our principal customers, the reduction or deferral of purchases, or changes in the mix of our products ordered by any one of these customers could cause our revenues to decline materially if we are unable to increase our revenues from other customers. Our customers, including our most significant customers, are not obligated by long-term contracts to purchase our products and may cancel orders with limited potential penalties. If any of our large customers reduces or cancels its purchases from us for any reason, it could have an adverse effect on our revenues and results of operations.

Cost of revenues and gross profit. The cost of revenues consists primarily of the cost of silicon wafers purchased from our foundry supplier, costs associated with the assembly, packaging and production testing of our ICs, outside processing costs associated with the manufacture of our products, royalties due to third parties, warranty costs, excess and obsolete inventory costs, depreciation and amortization, and costs of personnel associated with production management, quality assurance and services. In addition, after we purchase wafers from our foundries, we also face yield risk related to manufacturing these wafers into semiconductor devices. Manufacturing yield is the percentage of acceptable product resulting from the manufacturing process, as identified when the product is tested as a finished IC. If our manufacturing yields decrease, our cost per unit increases, which could have a significant adverse impact on our cost of revenues. We do not have long-term pricing agreements with foundry suppliers and contract manufacturers. Accordingly, our costs are subject to price fluctuations based on the overall cyclical demand for semiconductors.

We purchase our inventory pursuant to standard purchase orders. We estimate that lead times for delivery of our finished semiconductors from our foundry supplier and assembly, packaging and production testing subcontractor are approximately three to four months, lead times for delivery from our adapter card manufacturing subcontractor are approximately eight to ten weeks, and lead times for delivery from our switch systems manufacturing subcontractors are approximately twelve weeks. We build inventory based on forecasts of customer orders rather than the actual orders themselves.

We expect our cost of revenues as a percentage of sales to increase in the future as a result of a reduction in the average sale price of our products and a lower percentage of revenue deriving from sales of ICs and boards, which generally yield higher gross margins than our other products. This trend will depend on overall customer demand for our products, our product mix, competitive product offerings and related pricing and our ability to reduce manufacturing costs.

Operational Expenses

Research and Development Expenses.  Our research and development expenses consist primarily of salaries, share-based compensation and associated costs for employees engaged in research and development, costs associated with computer aided design software tools, qualification expenses, depreciation, amortization of intangibles, allocable facilities related and administrative expenses and tape-out costs. Tape-out costs are expenses related to the manufacture of new ICs, including charges for mask sets, prototype wafers, mask set revisions and testing incurred before releasing new ICs into production. We anticipate research and development expenses will increase in future periods based on an increase in personnel to support our product development activities and the introduction of new products.

Sales and Marketing Expenses. Sales and marketing expenses consist primarily of salaries, incentive compensation, share-based compensation and associated costs for employees engaged in sales, marketing and customer support, commission payments to third party sales representatives, advertising, trade shows and promotions, travel, amortization of intangibles, and allocable facilities related and administrative expenses. We expect these expenses will increase in future periods based on an increase in sales and marketing personnel and increased marketing activities.

General and Administrative Expenses. General and administrative expenses consist primarily of salaries, share-based compensation and associated costs for employees engaged in finance, legal, human resources and administrative activities, professional service expenses for accounting, corporate legal fees and allocable facilities related expenses. We expect these expenses will increase in absolute dollars in future periods based on an increase in personnel and professional services required to support our business activities.

Amortization of Intangible Assets. Amortization of intangible assets relates to intangible assets resulting from our acquisitions of businesses and purchases of patents and other license rights, which will be amortized over their estimated useful lives. Amortization is included in cost of revenues, research and development, sales and marketing or general and administrative expenses based upon the nature of the intangible asset.

22

Taxes on Income. Our operations in Israel have been granted “Approved Enterprise” status by the Investment Center of the Israeli Ministry of Economy (formerly, the Ministry of Industry, Trade and Labor) and “Beneficiary Enterprise” status by the Israeli Income Tax Authority, which makes us eligible for tax benefits under the Israeli Law for Encouragement of Capital Investments, 1959. Under the terms of the Beneficiary Enterprise program, income that is attributable to our operations in Yokneam, Israel will be exempt from income tax for a period of ten years commencing fiscal year 2011. Income that is attributable to our operations in Tel Aviv, Israel is subject to a reduced income tax rate (generally between 10% and the current corporate tax rate, depending on the percentage of foreign investment in the Company) for five to eight years beginning fiscal year 2013. The Yokneam tax holiday is expected to expire in 2020 and the Tel Aviv tax holiday is expected to expire between 2017 and 2020. The corporate tax rate in Israel was increased to 26.5% in 2014.

To prepare our consolidated financial statements, we estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating our actual tax exposure together with assessing temporary differences resulting from the differing treatment of certain items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheet.

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. We evaluate our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Our actual results could differ from these estimates.

We believe that the assumptions and estimates associated with revenue recognition, allowance for doubtful accounts, fair value of financial instruments, short-term investments, inventory valuation, valuation and impairment of goodwill and acquired intangibles, warranty provision, share-based compensation and income taxes have the greatest potential impact on our consolidated financial statements. Therefore, we consider these to be our critical accounting policies and estimates. For further information on all of our significant accounting policies, please see Note 1 of the accompanying notes to our consolidated financial statements.

See our Annual Report on Form 10-K for the year ended December 31, 2014, filed with the SEC on March 2, 2015, for a discussion of additional critical accounting policies and estimates. There have been no changes in our critical accounting policies as compared to what was disclosed in the Form 10-K for the year ended December 31, 2014.

Revenues. Revenues were $146.7 million for the three months ended March 31, 2015 compared to $99.0 million for the three months ended March 31, 2014, representing an increase of 48.2%. The year-over-year revenue increase was primarily due to higher sales of InfiniBand products into the HPC market, which benefitted from the CPU refresh cycle that started in the third quarter of 2014, as well as higher sales into the storage and EDC markets. In addition, the growth in revenues is attributed to increased sales of our 10Gb/s and 40Gb/s Ethernet products into Web 2.0 and cloud markets. Revenues from Infiniband FDR products increased as customers continued transitioning from QDR and lower data rates to the latest generation products. Revenues for the three months ended March 31, 2015 are not necessarily indicative of future results.

Gross Profit and Margin. Gross profit was $105.6 million for the three months ended March 31, 2015 compared to $65.3 million for the three months ended March 31, 2014, representing an increase of 61.8%. As a percentage of revenues, gross margin increased to 72.0% in the three months ended March 31, 2015 from 65.9% in the three months ended March 31, 2014. The gross margin improvement was primarily a result of changes in the product mix. Specifically, the portion of revenues attributed to ICs and boards increased in the three months ended March 31, 2015 while the portion of revenues attributable to switch and gateway systems declined. We garnish higher gross margins on sales of ICs and boards as compared to our other products. Gross margin for the three months ended March 31, 2015 is not necessarily indicative of future results.

Research and Development.

The following table presents details of our research and development expenses for the periods indicated:

	Three Months Ended March 31,
	2015		% of Revenues		2014		% of Revenues
	(in thousands)				(in thousands)
Salaries and benefits	$	31,707	21.6	%	$	24,356	24.6	%
Share-based compensation	6,768		4.6	%	6,678		6.7	%
Development and tape-out costs	6,843		4.7	%	7,039		7.1	%
Other	12,800		8.7	%	10,264		10.4	%
Total Research and development	$	58,118	39.6	%	$	48,337	48.8	%

24

Research and development expenses were $58.1 million in the three months ended March 31, 2015 compared to $48.3 million in the three months ended March 31, 2014, representing an increase of 20.2%. The increase in salaries and benefits and share-based compensation was attributable to headcount additions, merit increases and higher accrued bonuses under our annual discretionary bonus award program. The decrease in development and tape-out costs was attributable to a decrease in non-recurring engineering expenses and partially offset by higher equipment expenses. The increase in other research and development costs was primarily attributable to higher depreciation and amortization expenses, higher acquisition related charges, higher professional services and an increase in travel expenses. We expect that research and development expenses will increase in absolute dollars in future periods as we continue to devote more resources to develop new products, meet the changing requirements of our customers, develop new technologies and hire additional personnel.

Sales and marketing expenses were $22.6 million for the three months ended March 31, 2015 compared to $19.3 million for the three months ended March 31, 2014, representing an increase of 17.0%. The increase in salaries and benefits was attributable to headcount additions, merit increases and higher accrued bonuses under our annual discretionary bonus award program. The increase in trade shows and promotions expenses was primarily attributable to an increase in trade show fees and higher expenses related to equipment for customer product evaluations.

For a further discussion of share-based compensation included in sales and marketing expense, see “Share-based Compensation Expense” below.

General and Administrative.

The following table presents details of our general and administrative expenses for the periods indicated:

	Three Months Ended March 31,
	2015		% of Revenues		2014		% of Revenues
	(in thousands)				(in thousands)
Salaries and benefits	$	3,874	2.6	%	$	3,126	3.2	%

General and administrative expenses were $9.7 million for the three months ended March 31, 2015 compared to $8.2 million for the three months ended March 31, 2014, representing an increase of 18.1%. The increase in salaries and benefits was attributable to headcount additions, merit increases and higher accrued bonuses under our annual discretionary bonus award program. The increase in professional services costs was primarily due to legal fees.

For a further discussion of share-based compensation included in general and administrative expense, see “Share-based Compensation Expense” below.

Share-based Compensation Expense.

The following table summarizes the distribution of total share-based compensation expense in the consolidated statements of operations:

	Three Months Ended March 31,
	2015		2014
	(in thousands)
Cost of goods sold	$	547	$	522
Research and development	6,768		6,678
Sales and marketing	2,394		2,433
General and administrative	2,009		2,005
Total share-based compensation expense	$	11,718	$	11,638

Share-based compensation expenses were $11.7 million for the three months ended March 31, 2015, compared to $11.6 million for the three months ended March 31, 2014, representing an increase of 0.7%. The increase in share-based compensation expense was primarily due to RSUs granted to existing employees in the first quarter of fiscal 2015 and RSU grants to new hires during fiscal year 2014, partially offset by decreases from fully vested options and RSUs, and terminations.

At March 31, 2015, there were $98.5 million of total unrecognized share-based compensation costs related to non-vested share-based compensation arrangements. The costs are expected to be recognized over a weighted average period of 2.13 years.

Other Income, Net. Other income, net primarily consists of interest earned on cash and cash equivalents and short-term investments, impairment losses on equity investments in private companies, and foreign currency exchange gains and losses. Other loss, net was $2.5 million for the three months ended March 31, 2015 compared to other income, net of $0.2 million for the three months ended March 31, 2014. The change was primarily attributable to a $3.2 million impairment loss on an investment in a privately held company, partially offset by an increase of $0.3 million in interest income and gains on investments due to higher cash and investment balances and higher foreign currency exchange gains of $0.2 million.

Provision for Taxes on Income. Provision for taxes on income was $2.2 million for the three months ended March 31, 2015, compared to $0.7 million for the three months ended March 31, 2014. The effective tax rate was approximately 17.6% and (6.3%) for the three months ended March 31, 2015 and 2014, respectively. The difference between our effective tax rates and the 35% federal statutory rate resulted primarily from the tax holiday in Israel and foreign earnings taxed at rates lower than the federal statutory rates, partially offset by the accrual of unrecognized tax benefits, interest and penalties associated with unrecognized tax positions, non-tax-deductible expenses such as share-based compensation expense and losses generated from subsidiaries without tax benefits.

We assess our ability to recover our deferred tax assets on an ongoing basis. Significant management judgment is required in determining any valuation allowance recorded against deferred tax assets. In evaluating the ability to recover deferred tax assets, we consider available positive and negative evidence including its recent cumulative losses, our ability to carry-back losses against prior taxable income and its projected financial results. We also consider, commensurate with its objective verifiability, the forecast of future taxable income including the reversal of temporary differences and the implementation of feasible and prudent tax planning strategies. A valuation allowance may be recorded in the event it is deemed to be more-likely-than-not that the deferred tax asset cannot be realized.  Previously established valuation allowances may also be released in the event it is deemed to be more-likely-than-not that the deferred tax asset can be realized.  Any release of valuation allowance will be recorded as a tax benefit which will positively impact our operating results.  We believe, based on the quarterly assessment performed at March 31, 2015, that it is possible that a valuation allowance may be released in the future if sustained levels of profitability are achieved.

Liquidity and Capital Resources

Historically, we have financed our operations through a combination of sales of equity securities and cash generated by operations. As of March 31, 2015, our principal source of liquidity consisted of cash and cash equivalents of $61.7 million and short-term investments of $367.5 million. We expect that our current cash and cash equivalents and short-term investments and our cash flows from operating activities will be sufficient to fund our operations over the next twelve months after taking into account expected increases in research and development expenses, including tape out costs, higher sales and marketing and general and administrative expenses, capital expenditures to support our infrastructure and growth, and potential acquisitions. We are an Israeli company and as of March 31, 2015 our subsidiaries outside of Israel held approximately $28 million in cash and cash equivalents and short term investments. We do not earn a significant amount of our pre-tax income outside of Israel. We did not provide for Israeli income taxes on $1.4 million of our non-Israeli subsidiaries’ undistributed earnings as of March 31, 2015, as we currently have no plans to repatriate those funds and intends to indefinitely reinvest them in our non-Israeli operations.

Our cash position, short-term investments, restricted cash and working capital at March 31, 2015 and December 31, 2014 were as follows:

	March 31, 2015		December 31, 2014
	(in thousands)
Cash and cash equivalents	$	61,656	$	51,326
Short-term investments	367,468		334,038
Restricted cash, current	3,604		3,604
Total	$	432,728	$	388,968
Working capital	$	434,479	$	398,862

Our ratio of current assets to current liabilities was 4.6:1 at March 31, 2015 compared to 4.4:1 at December 31, 2014.

Operating activities

Net cash provided by our operating activities amounted to $45.8 million and $10.6 million in the three months ended March 31, 2015 and 2014, respectively. Net cash provided by operating activities in the three months ended March 31, 2015 was primarily attributable to net income of $10.5 million adjusted by net non-cash items of $24.2 million and changes in assets and liabilities of $11.1 million. The non-cash items consisted primarily of $11.7 million of share-based compensation and $9.5 million for depreciation and amortization The $11.1 million cash inflow from changes in assets and liabilities resulted primarily from a decrease in accounts receivable of $9.0 million primarily due to the timing of sales, an increase of $6.3 million in accrued and other liabilities, an increase in deferred revenue by $2.7 million and a decrease in prepaid expenses and other assets of $3.9 million, partially offset by an increase in inventories of $8.7 million as a result of our effort to fulfill forecasted sales and a decrease in accounts payable of $2.1 million primarily due to the timing of payments.

Net cash provided by operating activities in the three months ended March 31, 2014 was primarily attributable to net non-cash items of $21.3 million and changes in assets and liabilities of $0.2 million, partially offset by net loss of $11.0 million. The non-cash items consisted primarily of $11.6 million of share-based compensation and $10.0 million for depreciation and amortization. The $0.2 million cash inflow from changes in assets and liabilities resulted primarily from a decrease in accounts receivable of $5.0 million, partially offset by an increase in inventories of $2.9 million, an increase in prepaid expenses and other assets of $1.5 million and a decrease in accounts payable of $1.3 million primarily due to the timing of payments to vendors.

Financing activities

Our financing activities generated $6.9 million in the three months ended March 31, 2015. Cash provided by financing activities was primarily due to proceeds of $7.2 million from share option exercises and purchases pursuant to our employee share purchase plan, partially offset by principal payments on capital lease obligations of $0.3 million.

Our financing activities generated $6.3 million in the three months ended March 31, 2014. Cash provided by financing activities was primarily due to proceeds of $6.7 million from share option exercises and purchases pursuant to our employee share purchase plan, partially offset by principal payments on capital lease obligations of $0.4 million.

Off-Balance Sheet Arrangements

As of March 31, 2015, we did not have any off-balance sheet arrangements.

Contractual Obligations

The following table summarizes our contractual obligations at March 31, 2015, and the effect those obligations are expected to have on our liquidity and cash flows in future periods:

			Payments Due by Period
Contractual Obligations:	Total		Less Than 1 Year		1-3 Years		3-5 Years		Beyond 5 Years
	(in thousands)
Commitments under capital lease	$	1,341	$	829	$	512	$	—	$	—
Non-cancelable operating lease commitments	42,461		15,710		15,492		6,702		4,557
Purchase commitments	75,507		74,895		612		—		—
Total	$	119,309	$	91,434	$	16,616	$	6,702	$	4,557

For purposes of this table, purchase obligations for the purchase of goods or services are defined as agreements that are enforceable and legally binding and that specify all significant terms including: fixed or minimum purchase quantities; fixed, minimum or variable price provisions; and the approximate timing of the transaction. Our purchase orders are based on our current manufacturing needs and are fulfilled by our vendors within short time horizons. We do not have significant agreements for the purchase of raw materials or other goods specifying minimum quantities or set prices that exceed our expected requirements.

The contractual obligation table excludes our unrecognized tax benefit liabilities because we cannot make a reliable estimate of the timing of cash payments. As of March 31, 2015, our unrecognized tax benefits totaled $20.5 million, which would reduce our income tax expense and effective tax rate, if recognized.

Recent Accounting Standards

ITEM 3 — QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Fluctuation Risk

We do not have any long-term borrowings. Our investments consist of cash and cash equivalents, time deposits, money market funds and interest bearing investments in government debt securities, commercial paper and corporate bonds with an average maturity of 14 months. The primary objective of our investment activities is to preserve principal and ensure liquidity while maximizing income without significantly increasing risk. By policy, we limit the amount of our credit exposure through diversification and restricting our investments to highly rated securities. At the time of purchase, we do not invest more than 4% of the total investment portfolio in individual securities, except U.S. Treasury or agency securities. Highly rated long-term securities are defined as having a minimum Moody’s, Standard & Poor’s or Fitch rating of A2 or A, respectively. Highly rated short-term securities are defined as having a minimum Moody’s, Standard & Poor’s or Fitch rating of P-1, A-1 or F-1, respectively. We have not experienced any significant losses on our cash equivalents or short-term investments. We do not enter into investments for trading or speculative purposes. Our investments are exposed to market risk due to a fluctuation in interest rates, which may affect our interest income and the fair market value of our investments. Due to the short-term nature of our investment portfolio, we do not believe an immediate 1% change in interest rates would have a material effect on the fair market value of our portfolio, and therefore we do not expect our operating results or cash flows to be materially affected by a sudden change in market interest rates.

Foreign Currency Exchange Risk

We derive all of our revenues in U.S. dollars. The U.S. dollar is our functional and reporting currency in all of our foreign locations. However, a significant portion of our headcount related expenses, consisting principally of salaries and related personnel expenses, and our Israeli facility expenses are denominated in NIS. This foreign currency exposure gives rise to market risk associated with exchange rate movements of the U.S. dollar against the NIS. Furthermore, we anticipate that a material portion of our expenses will continue to be denominated in NIS. To the extent the U.S. dollar weakens against the NIS, we will experience a negative impact on our net income.

To protect against reductions in the value and the volatility of future cash flows caused by changes in foreign currency exchange rates, we have established a balance sheet and anticipated transaction risk management program. Currency derivative contracts and natural hedges are generally utilized in this hedging program. We do not enter into derivative contracts for trading or speculative purposes. Our hedging program reduces, but does not eliminate, the impact of currency exchange rate movements (see Part II, Item 1A, “Risk Factors”). If we were to experience a 10% change in currency exchange rates, the impact on assets and liabilities denominated in currencies other than the U.S. dollar, after taking into account hedges and offsetting positions, would result in a loss before taxes of approximately $0.3 million at March 31, 2015. There would also be an impact on future operating expenses denominated in currencies other than the U.S. dollar. At March 31, 2015, approximately $13.6 million of our monthly operating expenses were denominated in NIS. As of March 31, 2015, we had derivative contracts in place that hedged future operating expenses of approximately 347.3 million NIS, or approximately $87.3 million based upon the exchange rate on March 31, 2015. The derivative contracts cover a significant portion of future NIS denominated operating expenses expected to occur over the next twelve months. Our derivatives expose us to credit risk to the extent that the counterparties may be unable to meet the terms of the agreement. We seek to mitigate such risk by limiting our counterparties to major financial institutions and by spreading the risk across a number of major financial institutions. However, under current market conditions, failure of one or more of these financial institutions is possible and could result in incurred losses.

ITEM 4 — CONTROLS AND PROCEDURES

We maintain disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our CEO (principal executive officer) and CFO (principal financial officer), as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As required by SEC Rule 13a-15(b), we carried out an evaluation, under the supervision and with the participation of our management, including our CEO and CFO, of the effectiveness of our disclosure controls and procedures as of March 31, 2015. Per this evaluation, our CEO and CFO concluded that our disclosure controls and procedures were not effective as of March 31, 2015 because of the material weaknesses in our internal control over financial reporting described below.

Previously Identified Material Weaknesses in Internal Control Over Financial Reporting

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis.

29

We previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2014 the following control deficiencies that constituted material weaknesses in our internal control over financial reporting as of December 31, 2014, which still existed as of March 31, 2015.

·Control Environment - We did not maintain an effective control environment as we lacked sufficient oversight of activities related to our internal control over financial reporting. In addition, we did not maintain a sufficient complement of personnel with an appropriate level of knowledge, experience and training in internal control over financial reporting commensurate with our financial reporting requirements. As a result this contributed to the following material weaknesses in risk assessment and monitoring.

·Risk Assessment - We did not appropriately design controls in response to the risk of misstatement. This material weakness contributed to the following control deficiencies, which are considered material weaknesses:

·We did not design, document and maintain effective controls over our period-end financial reporting processes, including controls over the preparation, analysis and review of certain significant account reconciliations required to assess the appropriateness of account balances at period-end; and controls over the preparation and review of the consolidated interim and annual financial statements, including effective controls related to identifying and accumulating all required supporting information to determine the completeness and accuracy of the consolidated financial statements and disclosures.

·We did not design, document and maintain effective controls with respect to the accounting for revenue and related accounts receivable, including maintaining effective controls to prevent or detect errors in the processing of customer transactions. Specifically, we had insufficient controls related to the review of the accuracy of customer order entry and pricing.

·We did not design, document and maintain effective controls with respect to the accounting for inventory and related cost of sales accounts. Specifically, our controls over perpetual inventory records, which include our cycle count and annual physical inventory programs, were not appropriately designed or executed to validate the existence, completeness and accuracy of physical inventory quantities. In addition, we did not appropriately design controls related to the validation of assumptions used in the calculation of the provision for excess and obsolete inventory, as well as the completeness and accuracy of the underlying data used in the calculation.

·We did not design, document and maintain effective controls over access to the Company’s financial applications and data. Specifically, access review controls were not effectively designed to validate that access to certain financial applications and data were adequately restricted, which impacted controls that were dependent on the effective operation of restricted access.

·Monitoring - We did not design and maintain effective monitoring controls related to the design and operating effectiveness of certain controls involving an inherent level of complexity, subjectivity, and judgment related to the following business processes: revenue and accounts receivable, purchases and payables, period-end financial reporting, goodwill, intangible and finite-lived assets, hedging, income taxes, business combinations, and stock-based compensation. Specifically, we did not maintain sufficient documentation or perform a sufficient review of the control activities due to an insufficient complement of personnel with an appropriate level of experience, training and lines of reporting necessary to monitor control activities to allow for an effective internal control over financial reporting compliance group.

While these material weaknesses did not result in any material misstatement of our historical financial statements, they did result in adjustments to the accounting for business combinations, net revenue, accounts receivable, accrued liabilities, cost of revenues, and operating expenses and revisions to our consolidated financial statements for fiscal years 2013 and 2012, and interim periods in 2014, 2013 and 2012. Additionally, these material weaknesses could result in a misstatement of the account balances or disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

30

Status of Remediation Efforts

In response to the identified material weaknesses, our management, with oversight from our audit committee, has dedicated significant resources and efforts to improve our control environment and to remedy the identified material weaknesses. The following actions have been taken:

·Expanded and strengthened our internal audit organization, which reports directly to our audit committee, by hiring an Internal Audit Director as well as increasing the number of external consultants engaged by our internal audit organization;

·Devoted substantial effort in performing a comprehensive risk assessment process to identify, design, implement, and re-evaluate our control activities related to internal control over financial reporting, including monitoring controls related to the design and operating effectiveness of certain control activities;

·Instituted additional training programs for our world-wide finance and accounting personnel; and

·Strengthened procedures and set guidelines for documentation of review controls throughout our domestic and international locations for consistency of application.

We believe that the foregoing actions will support the improvement of our internal control over financial reporting, and through our efforts to identify, design and implement the necessary control activities, will be effective in remediating the material weaknesses described above. We will continue to devote significant time and attention to these remediation efforts. As we continue to evaluate and work to improve our internal control over financial reporting, management may determine to take additional measures to address the material weaknesses or determine to modify the remediation plan described above. Until the remediation steps set forth above, including the efforts to implement the necessary control activities we identify, are fully completed, the material weaknesses described above will continue to exist.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting during the Company’s fiscal quarter ended March 31, 2015 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1 — LEGAL PROCEEDINGS

See Note 7, “Commitments and Contingencies—Legal proceedings” of the Notes to the Unaudited Condensed Consolidated Financial Statements, included in Part I, Item 1 of this report, for a full description of legal proceedings and related contingencies and their effects on our condensed consolidated financial position, results of operations and cash flows.

We may, from time to time, become a party to various other legal proceedings arising in the ordinary course of business. We may also be indirectly affected by administrative or court proceedings or actions in which we are not involved, but which have general applicability to the semiconductor industry.

ITEM 1A — RISK FACTORS

Investing in our ordinary shares involves a high degree of risk. You should carefully consider the following risk factors, in addition to the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2014, the other information set forth in this report and our other filings with the SEC, before purchasing our ordinary shares. Each of these risk factors could harm our business, financial condition or operating results, as well as decrease the value of an investment in our ordinary shares.

There have been no material changes from risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2014, except for the following:

31

Risks Related to Our Business

We depend on a small number of customers for a significant portion of our sales, and the loss of any one of these customers will adversely affect our revenues.

A small number of customers account for a significant portion of our revenues. For the three months ended March 31, 2015, sales to Hewlett-Packard accounted for 12% of our total revenues, while sales to our top ten customers accounted for 60% of our revenues. For the three months ended March 31, 2014, sales to Dell accounted for 12% of our total revenues, while sales to our top ten customers accounted for 61% of our revenues. For the year ended December 31, 2014, sales to Hewlett-Packard, Dell and IBM accounted for 11%, 11% and 10%, respectively, of our total revenues, while sales to our top ten customers accounted for 62% of our revenues. Because the majority of servers, storage, communications infrastructure equipment and embedded systems are sold by a relatively small number of vendors, we expect that we will continue to depend on a small number of customers to account for a significant percentage of our revenues for the foreseeable future. Our customers, including our most significant customers, are not obligated by long-term contracts to purchase our products and may cancel orders with limited potential penalties. If any of our large customers reduces or cancels its purchases from us for any reason, it could have an adverse effect on our revenues and results of operations.

Risks Related to Operations in Israel and Other Foreign Countries

We are susceptible to additional risks from our international operations.

We derived 53% and 50% our revenues in the three months ended March 31, 2015 and 2014, respectively, from sales outside of North America. As a result, we face additional risks from doing business internationally, including:

·reduced protection of intellectual property rights in some countries;

·difficulties in staffing and managing foreign operations;

·longer sales and payment cycles;

·greater difficulties in collecting accounts receivable;

·adverse economic conditions;

·seasonal reductions in business activity;

·potentially adverse tax consequences;

·laws and business practices favoring local competition;

·costs and difficulties of customizing products for foreign countries;

·compliance with a wide variety of complex foreign laws and treaties;

·compliance with the United States’ Foreign Corrupt Practices Act and similar anti-bribery laws in other jurisdictions;

·compliance with export control and regulations;

·licenses, tariffs, other trade barriers, transit restrictions and other regulatory or contractual limitations on our ability to sell or develop our products in certain foreign markets;

·restrictive governmental actions, such as restrictions on the transfer or repatriation of funds and foreign investments;

·foreign currency exchange risks;

·fluctuations in freight rates and transportation disruptions;

·political and economic instability;

·variance and unexpected changes in local laws and regulations;

·natural disasters and public health emergencies; and

·trade and travel restrictions.

32

A significant legal risk associated with conducting business internationally is compliance with various and differing anti-corruption and anti-bribery laws and regulations of the countries in which we do business, including the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and similar laws in China. In addition, the anti-corruption laws in various countries are constantly evolving and may, in some cases, conflict with each other. Our Code of Ethics and Business Conduct and other policies prohibit us and our employees from offering or giving anything of value to a government official for the purpose of obtaining or retaining business and from engaging in unethical business practices, including kick-backs to or from purely private parties. However, there can be no assurance that all of our employees or agents will refrain from acting in violation of such laws and our related anti-corruption policies and procedures. Any such violation could have a material adverse effect on our business.

Our principal research and development facilities are located in Israel, and our directors, executive officers and other key employees are located primarily in Israel and the United States. In addition, we engage sales representatives in various countries throughout the world to market and sell our products in those countries and surrounding regions. If we encounter any of the above risks in our international operations, we could experience slower than expected revenue growth and our business could be harmed.

Risks Related to Our Ordinary Shares

The ownership of our ordinary shares will continue to be highly concentrated, and your interests may conflict with the interests of our existing shareholders.

As of March 31, 2015, based on information filed with the SEC or reported to us, Scopia Capital Management, LLC, Oracle Corporation, The Bank of New York Mellon Corporation and certain entities affiliated with Fidelity Management & Research Company beneficially owned an aggregate of approximately 30% of our outstanding ordinary shares, and taken together with our executive officers and directors and their affiliates, beneficially owned an aggregate of approximately 35% of our outstanding ordinary shares. Accordingly, these shareholders, should they act as a group, would have significant influence over the outcome of corporate actions requiring shareholder approval, including the election of directors, any merger, consolidation or sale of all or substantially all of our assets or any other significant corporate transaction. These shareholders could delay or prevent a change of control of our company, even if such a change of control would benefit our other shareholders. The significant concentration of share ownership may adversely affect the trading price of our ordinary shares due to investors’ perception that conflicts of interest may exist or arise.

The price of our ordinary shares may continue to be volatile, and the value of an investment in our ordinary shares may decline.

During the three months ended March 31 2015, our shares traded as low as $42.37 and as high as $48.92 per share. During the 12 months ended March 31. 2015 our shares traded as low as $30.58 per share and as high as $48.92 per share. Factors that could cause volatility in the market price of our ordinary shares include, but are not limited to:

·quarterly variations in our results of operations or those of our competitors;

·announcements by us, our competitors, our customers or rumors from sources other than our company related to acquisitions, new products, significant contracts, commercial relationships, capital commitments or changes in the competitive landscape;

·our ability to develop and market new and enhanced products on a timely basis;

·disruption to our operations;

·geopolitical instability;

·the emergence of new sales channels in which we are unable to compete effectively;

·any major change in our board of directors or management;

·changes in financial estimates, including our ability to meet our future revenue and operating profit or loss projections;

·changes in governmental regulations or in the status of our regulatory approvals;

33

·general economic conditions and slow or negative growth of related markets;

·commencement of, or our involvement in, litigation;

·changes in earnings estimates or recommendations by securities analysts;

·whether our operating results meet our guidance or the expectations of investors or securities analysts;

·continuing international conflicts and acts of terrorism; and

·changes in accounting rules.

FAIR VALUE MEASUREMENTS:

NOTE 3 — FAIR VALUE MEASUREMENTS:

Fair value hierarchy

The Company measures its financial instruments at fair value. The Company’s cash equivalents are classified within Level 1. Cash equivalents are valued primarily using quoted market prices utilizing market observable inputs. The Company’s investments in debt securities and certificates of deposits are classified within Level 2 as the market inputs to value these instruments consist of market yields, reported trades and broker/dealer quotes. In addition, foreign currency contracts are classified within Level 2 as the valuation inputs are based on quoted prices and market observable data of similar instruments. The Level 3 valuation inputs include the Company’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The inputs are unobservable in the market and significant to the instrument’s valuation.

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

NOTE 1 — THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Company

Mellanox Technologies, Ltd. (the “Company” or “Mellanox”) was incorporated in Israel and commenced operations in March 1999. Mellanox is a supplier of high-performance interconnect products for computing, storage and communications applications.

Principles of presentation

The unaudited condensed consolidated financial statements include the Company’s accounts as well as those of its wholly owned subsidiaries after the elimination of all intercompany balances and transactions.

The unaudited condensed consolidated financial statements included in this quarterly report on Form 10-Q have been prepared by the Company without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The year-end unaudited condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures contained in this quarterly report comply with the requirements of Section 13(a) of the Securities Exchange Act of 1934, as amended, for a quarterly report on Form 10-Q and are adequate to make the information presented not misleading. The unaudited condensed consolidated financial statements included herein reflect all adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods presented. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014, filed with the SEC on March 2, 2015. The results of operations for the three months ended March 31, 2015 are not necessarily indicative of the results to be anticipated for the entire year ending December 31, 2015 or thereafter.

Certain prior year amounts have been reclassified to conform to 2015 presentation. These changes and reclassifications did not impact net or comprehensive income.

Revision to Prior Period Financial Statements

During the year ended December 31, 2014, the Company became aware of and corrected immaterial errors primarily related to the accounting for liabilities for warranty, certain purchase orders, distributor price adjustment claims and purchase price allocation for the acquisitions of Kotura and IPtronics. The Company evaluated these errors and determined that the impact of the errors was not material to its results of operations, financial position or cash flows in previously issued financial statements. The Company has retrospectively revised financial information for all prior periods presented to reflect this correction. The impact of this revision for periods presented within this quarterly report on Form 10-Q are shown in the tables below:

Risks and uncertainties

The Company is subject to all of the risks inherent in a company which operates in the dynamic and competitive semiconductor industry. Significant changes in any of the following areas could have a materially adverse impact on the Company’s financial position and results of operations: unpredictable volume or timing of customer orders; ordered product mix; the sales outlook and purchasing patterns of the Company’s customers based on consumer demands and general economic conditions; loss of one or more of the Company’s customers; decreases in the average selling prices of products or increases in the average cost of finished goods; the availability, pricing and timeliness of delivery of components used in the Company’s products; reliance on a limited number of subcontractors to manufacture, assemble, package and production test the Company’s products; the Company’s ability to successfully develop, introduce and sell new or enhanced products in a timely manner; product obsolescence and the Company’s ability to manage product transitions; the timing of announcements or introductions of new products by the Company’s competitors; and the Company’s ability to successfully integrate acquired businesses.

Use of estimates

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the dates of the financial statements and the reported amounts of net revenue and expenses in the reporting periods. The Company regularly evaluates estimates and assumptions related to revenue recognition, allowances for doubtful accounts, sales returns and allowances, investment valuation, warranty reserves, inventory reserves, share-based compensation expense, long-term asset valuations, goodwill and purchased intangible asset valuation, hedge effectiveness, deferred income tax asset valuation, uncertain tax positions, litigation and other loss contingencies. These estimates and assumptions are based on current facts, historical experience and various other factors that the Company believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of revenue, costs and expenses that are not readily apparent from other sources. The actual results that the Company experiences may differ materially and adversely from the Company’s original estimates. To the extent there are material differences between the estimates and actual results, the Company’s future results of operations will be affected.

Significant accounting policies

There have been no changes in the Company’s significant accounting policies that were disclosed in its Annual Report on Form 10-K for the fiscal year ended December 31, 2014. See our Annual Report on Form 10-K for the year ended December 31, 2014, filed with the SEC on March 2, 2015, for a discussion of significant accounting policies and estimates.

Concentration of credit risk

The following table summarizes the revenues from customers (including original equipment manufacturers) in excess of 10% of the total revenues:

	Three Months Ended  March 31,
	2015		2014
Hewlett Packard	12	%	*
Dell	*		12	%

*Less than 10%

The following table summarizes the accounts receivable balance in excess of 10% of the total accounts receivable:

Ingram Micro	*		10	%

*Less than 10%

Product warranty

The following table provides the changes in the product warranty accrual for the three months ended March 31, 2015 and 2014:

	Three Months Ended March 31,
	2015			2014
	(In thousands)
Balance, beginning of the period	$	1,932		$	3,633
New warranties issued during the period	803			1,421
Reversal of warranty reserves	(67		)	(90		)
Settlements during the period	(806		)	(555		)
Balance, end of the period	$	1,862		$	4,409
Less: long term portion of product warranty liability	(421		)	(391		)
Balance, end of the period	$	1,441		$	4,018

Net income per share

The following table sets forth the computation of basic and diluted net loss per share for the periods indicated:

	Three Months Ended  March 31,
	2015		2014
Net income (loss)	$	10,496	$	(10,980	)
Basic and diluted shares:
Weighted average ordinary shares outstanding used to compute basic net income (loss) per share	45,691		44,276
Dilutive effect of employee share option and purchase plans	1,343		—
Shares used to compute diluted net income (loss) per share	47,034		44,276
Net income (loss) per share — basic	$	0.23	$	(0.25	)
Net income (loss) per share — diluted	$	0.22	$	(0.25	)

The Company excluded 592,035 and 895,280 outstanding shares for the three months ended March 31, 2015 and March 31, 2014, respectively, from the computation of diluted net income (loss) per ordinary share, because including these outstanding shares would have had an anti-dilutive effect.

Recent accounting pronouncements

On May 28, 2014, the FASB issued new accounting guidance related to revenue recognition. This new standard will replace all current GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. This guidance will be effective for the Company for the fiscal year beginning January 1, 2017 and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. Early adoption is not permitted. The Company is currently evaluating the impact of adopting this new accounting standard on its consolidated financial statements.

In August 2014, the FASB issued new guidance related to the disclosures around going concern. The new standard provides guidance around management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The new standard will be effective for the Company for the fiscal year ending December 31, 2016. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company’s financial statements.

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Principles of presentation

Principles of presentation

The unaudited condensed consolidated financial statements include the Company’s accounts as well as those of its wholly owned subsidiaries after the elimination of all intercompany balances and transactions.

The unaudited condensed consolidated financial statements included in this quarterly report on Form 10-Q have been prepared by the Company without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The year-end unaudited condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures contained in this quarterly report comply with the requirements of Section 13(a) of the Securities Exchange Act of 1934, as amended, for a quarterly report on Form 10-Q and are adequate to make the information presented not misleading. The unaudited condensed consolidated financial statements included herein reflect all adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods presented. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014, filed with the SEC on March 2, 2015. The results of operations for the three months ended March 31, 2015 are not necessarily indicative of the results to be anticipated for the entire year ending December 31, 2015 or thereafter.

Certain prior year amounts have been reclassified to conform to 2015 presentation. These changes and reclassifications did not impact net or comprehensive income.

Revision to prior period financial statements

Revision to Prior Period Financial Statements

During the year ended December 31, 2014, the Company became aware of and corrected immaterial errors primarily related to the accounting for liabilities for warranty, certain purchase orders, distributor price adjustment claims and purchase price allocation for the acquisitions of Kotura and IPtronics. The Company evaluated these errors and determined that the impact of the errors was not material to its results of operations, financial position or cash flows in previously issued financial statements. The Company has retrospectively revised financial information for all prior periods presented to reflect this correction. The impact of this revision for periods presented within this quarterly report on Form 10-Q are shown in the tables below:

Risks and uncertainties

Risks and uncertainties

The Company is subject to all of the risks inherent in a company which operates in the dynamic and competitive semiconductor industry. Significant changes in any of the following areas could have a materially adverse impact on the Company’s financial position and results of operations: unpredictable volume or timing of customer orders; ordered product mix; the sales outlook and purchasing patterns of the Company’s customers based on consumer demands and general economic conditions; loss of one or more of the Company’s customers; decreases in the average selling prices of products or increases in the average cost of finished goods; the availability, pricing and timeliness of delivery of components used in the Company’s products; reliance on a limited number of subcontractors to manufacture, assemble, package and production test the Company’s products; the Company’s ability to successfully develop, introduce and sell new or enhanced products in a timely manner; product obsolescence and the Company’s ability to manage product transitions; the timing of announcements or introductions of new products by the Company’s competitors; and the Company’s ability to successfully integrate acquired businesses.

Use of estimates

Use of estimates

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the dates of the financial statements and the reported amounts of net revenue and expenses in the reporting periods. The Company regularly evaluates estimates and assumptions related to revenue recognition, allowances for doubtful accounts, sales returns and allowances, investment valuation, warranty reserves, inventory reserves, share-based compensation expense, long-term asset valuations, goodwill and purchased intangible asset valuation, hedge effectiveness, deferred income tax asset valuation, uncertain tax positions, litigation and other loss contingencies. These estimates and assumptions are based on current facts, historical experience and various other factors that the Company believes to be reasonable under the circumstances, he results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of revenue, costs and expenses that are not readily apparent from other sources. The actual results that the Company experiences may differ materially and adversely from the Company’s original estimates. To the extent there are material differences between the estimates and actual results, the Company’s future results of operations will be affected.

Concentration of credit risk

Less: long term portion of product warranty liability	(421		)	(391		)
Balance, end of the period	$	1,441		$	4,018

Net income per share

Net income per share

The following table sets forth the computation of basic and diluted net loss per share for the periods indicated:

	Three Months Ended  March 31,
	2015		2014
Net income (loss)	$	10,496	$	(10,980	)
Basic and diluted shares:
Weighted average ordinary shares outstanding used to compute basic net income (loss) per share	45,691		44,276
Dilutive effect of employee share option and purchase plans	1,343		—
Shares used to compute diluted net income (loss) per share	47,034		44,276
Net income (loss) per share — basic	$	0.23	$	(0.25	)
Net income (loss) per share — diluted	$	0.22	$	(0.25	)

The Company excluded 592,035 and 895,280 outstanding shares for the three months ended March 31, 2015 and March 31, 2014, respectively, from the computation of diluted net income (loss) per ordinary share, because including these outstanding shares would have had an anti-dilutive effect.

Recent accounting pronouncements

Recent accounting pronouncements

On May 28, 2014, the FASB issued new accounting guidance related to revenue recognition. This new standard will replace all current GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. This guidance will be effective for the Company for the fiscal year beginning January 1, 2017 and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. Early adoption is not permitted. The Company is currently evaluating the impact of adopting this new accounting standard on its consolidated financial statements.

In August 2014, the FASB issued new guidance related to the disclosures around going concern. The new standard provides guidance around management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The new standard will be effective for the Company for the fiscal year ending December 31, 2016. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company’s financial statements.

The purchase orders are based on the Company’s current manufacturing needs. The Company does not have significant agreements for the purchase of raw materials or other goods specifying minimum quantities or set prices that exceed its expected requirements.

Legal proceedings

The Company is currently involved in various legal proceedings. Unless otherwise noted below, during the periods presented the Company did not record any accrual for loss contingencies associated with such legal proceedings, determined that an unfavorable outcome is probable or reasonably possible, or determine that the amount or range of any possible loss is reasonably estimable. The Company is engaged in other legal actions not described below arising in the ordinary course of its business and, while there can be no assurance, it believes that the ultimate outcome of these actions will not have a material adverse effect on its operating results, liquidity or financial position.

Pending legal proceedings as of March 31, 2015 were as follows:

Avago Technologies Fiber (IP) Singapore Pte. Ltd.vs. IPtronics, Inc. and IPtronics A/S

On September 29, 2010, Avago Technologies Fiber (IP) Singapore Pte. Ltd. (“Avago IP”) filed a complaint for patent infringement against IPtronics, Inc. and IPtronics A/S (now Mellanox Technologies Denmark Aps) (collectively, “IPtronics”) now pending  in the United States District Court, Northern District of California, San Jose Division (Case No.: 5:10-cv-02863 EJD), asserting infringement of the 456 patent and U.S. Patent No. 5,359,447. On September 11, 2012, Avago IP along with additional subsidiaries of Avago Technologies Limited (collectively, “Avago”) filed a second amended and supplemental complaint against the IPtronics adding allegations that IPtronics engaged in violations of the Lanham Act, Section 43 (A); misappropriated Avago’s trade secrets; engaged in unfair competition against Avago; intentionally interfered with Avago’s contractual relations; and were unjustly enriched by and through the conduct complained of by Avago. A motion to file a third amended complaint was filed but never granted.

Avago’s motion to file a Fourth Amended and Supplemental Complaint (the “Complaint”) to add the Company and a new claim for interference with prospective economic advantage against IPtronics was granted. The Company and IPtronics have answered the new complaint and the case is set for trial in May-June, 2016. IPtronics’ motion to add an antitrust counterclaim against Avago for pursuing a sham action was denied and, as explained below, that claim is being pursued in a separate action.

Pursuant to the Complaint, Avago seeks unspecified damages, treble damages, injunctive relief and any other relief deemed just and proper by the court. Neither the outcome of the proceeding nor the amount and range of potential damages or exposure associated with the proceeding can be assessed with certainty. In the event IPtronics is not successful in defending the Complaint, the Company could be forced to license technology from Avago and be prevented from importing, selling, offering for sale, advertising, soliciting, using and/or warehousing for distribution the allegedly infringing products. Based on currently available information, the Company believes that the resolution of this proceeding is not likely to have a material adverse effect on the Company’s business, financial position, results of operations or cash flows.

IPtronics Inc. and Mellanox Technologies Denmark ApS vs. Avago Technologies Inc., et al.

IPtronics has filed an antitrust Complaint in the United States District Court, Northern District of California, San Jose Division (Case No.: 5:14-cv-05647-BLF (PSG)), against the US and foreign Avago entities (collectively “Avago”) for pursuing what the Company believes to be a baseless ITC action against IPtronics. The Complaint seeks unspecified damages in an amount to compensate IPtronics for the damages resulting from the Avago Entities’ alleged illegal conduct. In response to the Complaint Avago filed a motion to dismiss which will be heard on June 11, 2015. No case schedule has been set.

Weinberger Case

On February 20, 2013, a request for approval of a class action was filed in the Economic Division of the District Court of Tel Aviv-Jaffa against Mellanox Technologies, Ltd., the Company’s President and CEO, former CFO, CFO and each of the members of the Company’s board of directors (the “Israeli Claim”). The Israeli Claim was filed by Mr. Avigdor Weinberger (the “Claimant”). The Israeli Claim alleges that the Company, the board members, the Company’s President and CEO, its former CFO and its current CFO are responsible for making misleading statements (or failing to disclose certain facts) and filings to the public, as a result of which the shares of the Company were allegedly traded at a higher price than their true value during a period commencing on April 19, 2012 and ending January 2, 2013 and, therefore, these parties are responsible for damages caused to the purchasers of the Company’s shares on the Tel Aviv Stock Exchange during this time. The Claimant seeks an award of compensation to the relevant shareholders for all damages caused to them, including attorney fees and Claimant’s fee and any other relief deemed just and proper by the court. On April 24, 2013, the Claimant and the Company filed a procedural agreement with the court to stay the Israeli Claim pending the completion of the In re Mellanox Technologies, Ltd. Securities Litigation disclosed herein. On April 24, 2013, the Israeli court approved this procedural agreement and stayed the Israeli proceedings.

On January 7, 2015 the plaintiff, with the consent of the Company, filed a request to withdraw the Israeli Claim (and related class action claim) against the Company and the Board (the “Withdrawal Petition”) after the plaintiff, in view of the decision to dismiss the U. S. Class Action (In re Mellanox Technologies, Ltd. Securities Litigation disclosed herein), reached the conclusion that it would be difficult for the plaintiff to prove the Israeli Claim and have the complaint approved as a class action. Neither the plaintiff nor its attorneys received or will receive any benefit in return for their withdrawal.

On January 8, 2015, the Israeli Court approved the Withdrawal Petition and dismissed the Israeli Claim.

Infinite Data Case

On February 19, 2013, Infinite Data LLC, a Delaware limited liability company (“Infinite Data”) and a non-practicing entity and exclusive licensee of U.S. patent number 5,790,530 (the “Patent”), filed suit against approximately 25 of the Company’s end users and direct customers of its InfiniBand products in the United States District Court in Delaware. All actions included the same allegation of infringement regarding the Patent and seek the payment of damages, costs, expenses and injunctive relief. Several of the end users and direct customers sued by Infinite Data tendered indemnification requests to the Company on the basis of existing contractual or asserted statutory obligations imposed on the Company to provide such indemnification. All of these cases were stayed pending the outcome of the declaratory judgment action filed by the Company (see below). Based on currently available information, the Company believes that the resolution of these proceedings is not likely to have a material adverse effect on the Company’s business, financial position, results of operations or cash flows.

In response to these filings and accusations of infringement by the Company’s products, on May 21, 2013, the Company filed a declaratory judgment complaint against Infinite Data asking for a declaration that the Patent is invalid and that the Company’s products do not infringe. On November 14, 2013, Infinite Data filed its answer denying that the Patent was invalid and counterclaimed that the Company’s products infringe. Pursuant to the Counterclaims, Infinite Data seeks unspecified damages, treble damages, injunctive relief and any other relief deemed just and proper by the court.

Infinite Data, Mellanox Technologies, Ltd. and Mellanox Technologies, Inc. each entered into settlement agreements in which Infinite Data agreed to dismiss Mellanox Technologies, Ltd., with no liability or payment made by Mellanox Technologies, Ltd. and to dismiss Mellanox Technologies, Inc. in exchange for a payment of $1.3M. The case against Mellanox Technologies, Ltd. was dismissed with prejudice on December 3, 2014 and the case against Mellanox Technologies, Inc. was dismissed with prejudice on January 5, 2015. In accordance with the terms of the settlement agreement, Infinite Data has dismissed with prejudice its complaints against all of Mellanox Technologies, Inc.’s direct and indirect customers except Ford, which dismissal is still pending.

NOTE 10 — INCOME TAXES:

As of March 31, 2015 and December 31, 2014, the Company had gross unrecognized tax benefits of $20.5 million and $18.0 million, respectively. It is the Company’s policy to classify accrued interest and penalties as part of the unrecognized tax benefits and record the expense in the provision for income taxes. As of March 31, 2015 and December 31, 2014, the amount of accrued interest and penalties totaled $1.0 million and $1.0 million, respectively. As of March 31, 2015, calendar years 2009 and thereafter are open and subject to potential examination in one or more jurisdictions. The Beneficiary Enterprise tax holiday associated with the Company’s Yokneam and Tel Aviv operations began in 2011. The tax holiday for the Company’s Yokneam operations will expire in 2020 and the Tax Holiday for the Company’s Tel-Aviv operations will expire between the years 2017 and 2020. The tax holiday has resulted in a cash tax savings of $6.1 million and $0.2 million in the three months ended March 31, 2015 and March 31, 2014 respectively, increasing diluted earnings per share by approximately $0.13 and $0.01 in the three months ended March 31, 2015 and March 31, 2014 respectively.

The Company’s effective tax rate is highly dependent upon the geographic distribution of its worldwide earnings or losses, tax regulations and tax holiday benefits in Israel, and the effectiveness of the Company’s tax planning strategies. The Company’s effective tax rates were 17.6% and (6.3%) for the three months ended March 31, 2015 and 2014, respectively. The difference between the Company’s effective tax rates and the 35% federal statutory rate resulted primarily from the tax holiday in Israel and foreign earnings taxed at rates lower than the federal statutory rates, partially offset by the accrual of unrecognized tax benefits, interest and penalties associated with unrecognized tax positions, non-tax-deductible expenses such as share-based compensation and losses generated from subsidiaries without tax benefit.

The application of income tax law is inherently complex. Laws and regulations in this area are voluminous and are often ambiguous, and the Company is required to make many subjective assumptions and judgments regarding its income tax exposures. In addition, interpretations of and guidance surrounding income tax laws and regulations are subject to change over time. Any changes in the Company’s subjective assumptions and judgments could materially affect amounts recognized in its consolidated balance sheets and statements of income.

The Company assesses its ability to recover its deferred tax assets on an ongoing basis. Significant management judgment is required in determining any valuation allowance recorded against deferred tax assets. In evaluating the ability to recover deferred tax assets, the Company considers available positive and negative evidence including its recent cumulative losses, its ability to carry-back losses against prior taxable income and its projected financial results. The Company also considers, commensurate with its objective verifiability, the forecast of future taxable income including the reversal of temporary differences and the implementation of feasible and prudent tax planning strategies. A valuation allowance may be recorded in the event it is deemed to be more-likely-than-not that the deferred tax asset cannot be realized.  Previously established valuation allowances may also be released in the event it is deemed to be more-likely-than-not that the deferred tax asset can be realized.  Any release of valuation allowance will be recorded as a tax benefit which will positively impact the Company’s operating results.  The Company believes, based on the quarterly assessment performed at March 31, 2015, that it is possible that a valuation allowance may be released in the future if sustained levels of profitability are achieved.
