THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:	3 Months Ended
	Mar. 31, 2015
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.

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.

FAIR VALUE MEASUREMENTS:
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. As of March 31, 2015 and December 31, 2014, the Company did not have any financial instruments valued based on Level 3 valuations.

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.

INCOME_TAXES

INCOME TAXES:
INCOME TAXES:	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.

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.

	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.
