	In the opinion of the management of Emulex Corporation (Emulex or the Company), the accompanying unaudited condensed consolidated financial statements contain adjustments, including normal recurring accruals necessary to present fairly the Company’s consolidated financial position, results of operations, comprehensive loss, and cash flows. Interim results for the three months ended September 28, 2014 are not necessarily indicative of the results that may be expected for the fiscal year ending June 28, 2015. The accompanying condensed consolidated interim financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended June 29, 2014. The preparation of the condensed consolidated financial statements requires the use of estimates and actual results could differ materially from management’s estimates.
	The accompanying consolidated financial statements include the accounts of Emulex and its wholly-owned subsidiaries. Material intercompany transactions and balances have been eliminated in consolidation.
	The Company has a 52 or 53-week fiscal year that ends on the Sunday nearest to June 30. Accordingly, every fifth or sixth fiscal year will be a 53-week fiscal year. Fiscal 2015 is a 52-week fiscal year. The last 53-week fiscal year was fiscal 2011.

	Fair Value Measurements
	Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy is based on three levels of inputs that may be used to measure fair value, of which the first two are considered observable and the last unobservable. A description of the three levels of inputs is as follows:
	Level 1 -	Quoted prices (unadjusted) in active markets for identical assets or liabilities;
	Level 2 -	Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and
	Level 3 -	Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	Assets and Liabilities Measured at Fair Value on a recurring basis:

	Assets and Liabilities Measured at Fair Value on a Non-recurring Basis
	The Company measures the fair value of its assets acquired and liabilities assumed in a business combination, and goodwill and other long lived assets when they are held for sale or determined to be impaired. There were no such non-recurring measurements during the first quarter of fiscal 2015.
	Fair Value of Financial Instruments Not Measured at Fair Value
	The total fair value of the Convertible Senior Notes at September 28, 2014 was $155.5 million, which was estimated based on recent market transaction prices, a Level 2 fair value measurement.

	Goodwill and Intangible Assets, net
	There was no activity in goodwill during the three months ended September 28, 2014.
	The Company tests goodwill for impairment annually during the fourth fiscal quarter and at other times if events have occurred or circumstances exist that indicate the carrying value of goodwill may no longer be recoverable. Given the recent volatility of the Company's market capitalization, the inherent uncertainty in forecast and identification of triggering events, and the fact that the fair value of the Company's reporting units did not exceed their carrying value by a substantial margin during the annual impairment test during the fourth fiscal quarter, it is possible that the Company's goodwill could become impaired in the near term.

	Fourth Quarter of Fiscal 2014 Restructuring
	During the fourth quarter of fiscal 2014, the Company recorded restructuring charges of approximately $1.1 million primarily consisting of severance due to workforce reductions. These severance related charges are expected to be substantially paid in cash by the second quarter of fiscal 2015.
	Second Quarter of Fiscal 2014 Restructuring
	During the second quarter of fiscal 2014, the Company initiated a restructuring plan designed to streamline business operations and reduce operating expenses. The total restructuring charge was approximately $8.1 million. The restructuring actions include a reduction in workforce of approximately 15%, the consolidation of certain engineering facilities, and the closure of the Company's Bolton, Massachusetts facility. All restructuring actions impacted the Connectivity segment. The restructuring plan was substantially completed by the end of the first quarter of fiscal 2015.

	Broadcom Patent Infringement Litigation
	During fiscal 2010, Broadcom Corporation (Broadcom) filed a patent infringement lawsuit containing 300 claims against the Company alleging infringement of eleven patents. On April 3, 2012, United States District Court in the Central District of California (District Court) issued a permanent injunction (2012 Permanent Injunction) against further sale of products found to infringe U.S. Patent 7,058,150 (the ‘150 patent) and 7,471,691 (the ‘691 patent), but permitting sales of products manufactured outside the U.S. to customers located outside the U.S., design around efforts including modifications and design, development, and testing to eliminate infringement, and service and technical support for certain products. This injunction remains in place but the effects have been mitigated in a number of ways. First, with product redesigns. Second, with license agreements from Broadcom to our customers whose products were affected by the injunction. Third, Broadcom and the Company entered into a settlement agreement on July 3, 2012 which provided the Company with a worldwide limited license to the ‘691 patent, the ‘150 patent, and U.S. Patents 6,424,194; 7,486,124 and 7,724,057 [collectively, the ‘194 Patent family], for certain fields of use including Fibre Channel applications. Under this settlement agreement, the Company paid a lump sum of approximately $58.0 million in the first quarter of fiscal 2013. Fourth, the Company and Broadcom entered into a Dismissal and Standstill Agreement described below.
	Approximately $36.8 million of the $58.0 million payment was expensed in fiscal 2012. The remainder of approximately $21.2 million was recorded as prepaid license fees and is being amortized to cost of goods sold over the ten year license term in proportion to the estimated future revenues of such licensed technology. As of September 28, 2014, the unamortized prepaid license fee was approximately $12.1 million, of which approximately $3.6 million was recorded in prepaid expenses and other current assets and approximately $8.5 million was recorded in other assets. The Company recognized amortization expense related to such prepaid license fees of approximately $1.0 million during both the three months ended September 28, 2014 and September 29, 2013.
	Effective March 30, 2014, the Company and Broadcom entered into a Dismissal and Standstill Agreement (the "Dismissal Agreement") pursuant to which the Company and Broadcom agreed to dismiss, without prejudice, certain claims that had been scheduled for retrial in September 2014 and not to pursue certain other claims for one year. The claims subject to standstill relate to the SerDes Patents (defined below) based solely on the use, manufacture, sale or import of certain Emulex products that were named in the original lawsuit. SerDes Patents means U.S. Patent Nos. 6,424,194; 7,038,516; 7,125,169; 7,486,124; and 7,724,057, and any reissues, foreign counterparts, continuations, continuations-in-part, divisionals or reexaminations of such patents. The Dismissal Agreement does not prevent, after the expiration of the one year standstill, Broadcom from bringing an infringement claim seeking an injunction or damages with respect to infringement of the SerDes Patents relating to the Standstill Products. In the Dismissal Agreement, Emulex agreed to pay Broadcom, a non-refundable, non-cancelable dismissal and standstill fee for $5 million, of which approximately $3.8 million was included in Accrued and Other Current Liabilities as of September 28, 2014.
	Through September 28, 2014, the Company has incurred approximately $21.9 million of mitigation, product redesign and appeal related expenses, of which approximately $0.2 million and $2.5 million were recorded during the three months ended September 28, 2014 and September 29, 2013, respectively. The Company expects to incur incremental mitigation and appeal related expenses during fiscal 2015 up to approximately $0.3 million, to be recorded within operating expenses. In addition, the Company has agreed to participate in certain customer royalty obligations arising under license agreements with Broadcom with respect to the infringing products. Through September 28, 2014, the Company has recorded approximately $5.2 million in cost of sales related to such customer obligations, of which approximately $0.8 million and $0.5 million were recorded in cost of sales for the three months ended September 28, 2014 and September 29, 2013, respectively. The Company may incur additional amounts related to these obligations of approximately $5 million in future periods, all of which will reduce gross margins in the periods accrued.
	While the Company has contractual commitments from its suppliers concerning the defense and indemnification of certain Broadcom claims relating to certain technology provided by such suppliers, and is pursuing certain claims for reimbursement against certain of its suppliers, it cannot be certain that such defense and indemnification obligations will be honored by such suppliers or that any related legal proceedings will result in any material reimbursement to the Company. This lawsuit continues to present risks with respect to U.S. sales of certain Ethernet products that could have a material adverse affect on the Company’s business, financial condition, or results of operations, including loss of patent rights, monetary damages, potential reimbursement of customer indemnification liabilities or royalty obligations, and injunction against the sale of accused products.
	Shareholder Lawsuits
	On May 21, 2014, a derivative shareholder complaint was filed in the United States District Court in the Central District of California (Case No. 8:14-cv-0076-DOC-JCG) alleging damages incurred by Emulex and naming eight of the Company's eleven directors as defendants. The lawsuit alleges that Emulex was damaged by expenses for the repurchases of Emulex stock and by the implementation of cost reductions. An amended federal complaint was filed on July 14, 2014 in which the original plaintiff was dropped from the complaint and a different plaintiff was added. On August 15, 2014, the Company filed a motion to dismiss the complaint, which is scheduled to be heard on November 24, 2014. Management is unable to determine whether any loss will occur or to estimate the range of such loss, therefore, no amount of loss has been accrued.
	On July 17, 2014, a derivative shareholder complaint was filed in the Superior Court of the State of California for the County of Orange (Case No. 30-2014-00734802-CU-SL-CXC) alleging damages incurred by Emulex and naming eight of the Company's eleven directors as defendants. The lawsuit alleges that Emulex was damaged by expenses for the repurchases of Emulex stock and by the implementation of cost reductions. On August 7, 2014, the parties filed a stipulation to stay the State Derivative Action pending the resolution of the motion to dismiss the Federal derivative action described in the preceding paragraph. Management is unable to determine whether any loss will occur or to estimate the range of such loss, therefore, no amount of loss has been accrued.
	In addition to the ongoing litigation discussed above, the Company is involved in various claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of the open matters will not have a material adverse affect on the Company’s consolidated financial position, results of operations or liquidity.
	Other Commitments and Contingencies
	The Company provides limited indemnification in selected circumstances within its various customer contracts whereby the Company indemnifies the parties to whom it sells its products with respect to the Company’s product infringement of certain intellectual property, and in some limited cases against bodily injury or damage to real or tangible personal property caused by a defective Company product. It is not possible to predict the maximum potential amount of future payments under these or similar agreements, due to the conditional nature of the Company’s obligations and the unique facts and circumstances involved in each particular agreement. As of September 28, 2014, the Company has not incurred any significant costs related to contractual indemnification of its customers.

	Convertible Senior Notes
	In November 2013, the Company issued $175.0 million aggregate principal amount of 1.75% Convertible Senior Notes due November 15, 2018 ("Convertible Senior Notes") in a private placement offering at a price equal to 100% of the principal amount thereof. Interest is payable semi-annually in arrears on May 15 and November 15 of each year, commencing May 15, 2014. The Company may be required to pay additional interest upon occurrence in certain events as outlined in the indenture governing the Convertible Senior Notes. The Convertible Senior Notes are unsecured and rank senior to the Company's future indebtedness that is expressly subordinated to the Convertible Senior Notes, equal with existing and future indebtedness that are not so subordinated and junior to any future secured indebtedness, all existing and future debt and other liabilities of the Company's subsidiaries. As of September 28, 2014, the remaining term of the Convertible Senior Notes is 4.1 years.
	The Convertible Senior Notes are convertible, subject to certain conditions, into shares of the Company's common stock at an initial conversion price of approximately $10.30 per share, or 97.13 shares of the Company's common stock per $1,000 in principal amount of the Convertible Senior Notes. The conversion rate is subject to adjustment for certain events as outlined in the indenture governing the Convertible Senior Notes. On or prior to August 15, 2018, holders may convert their Convertible Senior Notes at their option under the following circumstances: (1) during any fiscal quarter after December 29, 2013, if the closing price of the Company's common stock for at least 20 trading days during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of Convertible Senior Notes was less than 98% of the product of the last reported sale price of the Company's common stock and the applicable conversion rate on such date; or (3) upon the occurrence of certain corporate transactions or specified distributions described in the indenture. Upon conversion, the principal amount of the Convertible Senior Notes will be paid in cash and the conversion spread will be paid in shares or cash at the Company’s election. As of September 28, 2014, the “if-converted” value of the Convertible Notes did not exceed its principal amount and none of the conditions allowing holders of the Convertible Senior Notes to convert had been met.
	The Company may not redeem the Convertible Senior Notes prior to maturity. However, in the event of a fundamental change, as defined in the indenture, the holders of the Convertible Senior Notes have the option to require the Company to repurchase all or a portion of their Convertible Senior Notes at a purchase price equal to 100% of the principal amount of the Convertible Senior Notes, plus accrued and unpaid interest. Holders who convert their Convertible Senior Notes in connection with a make-whole fundamental change, as defined in the indenture, may be entitled to an increase in the conversion rate.
	Based on the terms of the embedded stock conversion option, the conversion option was determined to be indexed to the Company's stock. Accordingly, the conversion option was not accounted for separately as a derivative.
	At the date of issuance, the Company separated the Convertible Senior Notes into liability and equity components. The liability component was determined by measuring the fair value of a similar instrument excluding the conversion feature. The equity component, which reflects the value of the conversion feature at issuance, was recognized as the difference between the proceeds from the issuance of the Convertible Senior Notes and the fair value of the liability component, and recorded as additional paid-in capital. The excess of the principal amount of the liability component over its carrying amount of approximately $32.0 million is being amortized to interest expense over the term of the Convertible Senior Notes, using the effective interest rate method. The equity component is not remeasured as long as it continues to meet the conditions of equity classification.
	The Company recorded total issuance costs of approximately $5.3 million, which have been allocated on a pro-rata basis to the debt and equity components, consistent with the allocation of the Convertible Senior Notes. The debt issuance costs attributable to the liability component of approximately $4.3 million were recorded in other assets and are being amortized over the term of the Convertible Senior Notes. The debt issuance costs attributable to the equity component of approximately $1.0 million were netted against the equity component of the Convertible Senior Notes and recorded as a reduction to additional paid-in capital. Debt issuance costs, net of amortization, were approximately $3.8 million as of September 28, 2014.
	The carrying values of the liability and equity components of the Convertible Senior Notes consisted of the following as of September 28, 2014:
			(in thousands)
	Liability component:
	Principal amount		$	175,000

	In November 2013, the Company's Board of Directors approved a $200.0 million share repurchase program that superseded the existing share repurchase program authorized in August 2008. The share repurchases are authorized to be completed through the combination of individually negotiated transactions, accelerated share buybacks, and open market purchases.
	As of September 28, 2014, the Company repurchased approximately 22.5 million shares, at an average price of $6.68, for a total of approximately $150.0 million, recorded as treasury stock. No shares were repurchased during the three months ended September 28, 2014.
	As of September 28, 2014, approximately $50.0 million remains under the authorized repurchase program.

	Income Taxes
	As of September 28, 2014, the liability for income taxes associated with uncertain tax positions was approximately $40.2 million for which a reasonably reliable estimate for the period of payment cannot be made. If fully recognized, approximately $26.5 million of such liability would impact the Company’s effective tax rate. Absent any resolution of the on-going audit by the Internal Revenue Service (IRS) discussed below, the Company does not expect that the liability for unrecognized tax benefits will change significantly within the next 12 months.
	The Company’s federal income tax returns for fiscal years 2008 to 2013 and California income tax returns for fiscal years 2008 to 2013 are open as the statutes of limitations have not yet expired or have been extended. The Company's federal income tax returns for fiscal 2010 to 2013 are currently under examination by the IRS. Additionally, the Company’s California income tax returns for fiscal years 2008 and 2009 are currently under examination by the California Franchise Tax Board. The Company is also currently under audit by various state and international taxing authorities. In foreign jurisdictions, with few exceptions, the Company is subject to examinations for all years subsequent to fiscal 2010. The Company does not expect any audits for these foreign jurisdictions to have a material affect on the results of operations or financial position.
	The IRS completed its examination of the Company’s federal income tax returns for fiscal years 2008 and 2009 and the amended return filed for fiscal year 2007 and issued a 30-Day Letter in March 2014. In the 30-Day Letter, the IRS proposed adjustments related to the amount of "buy-in-payments" made by one of the international subsidiaries to the Company in connection with the cost-share agreement entered into by the Company and its international subsidiary in fiscal year 2008. The incremental tax liability asserted in the 30-Day Letter is approximately $70.0 million, excluding interest and penalties. Upon the 30th day from the issuance of the 30-Day Letter from the IRS, the Company began accruing additional interest and will continue to do so until resolution. The Company responded to the 30-Day Letter in May 2014, disagreeing with the IRS' proposed adjustments and the basis for its positions, and administratively appealed to the IRS Appeals Office. The IRS has assigned the audit to the IRS Office of Appeals in Los Angeles, California.
	The Company has previously accrued for what it believes are adequate amounts of tax and related interest, if any, that may result from these state and federal examinations. Such accruals are reviewed quarterly and adjusted as events occur that affect potential liabilities for additional taxes, such as lapsing of applicable statutes of limitations, proposed assessments by tax authorities, negotiations with tax authorities, identification of new issues, and issuance of new regulations or case law. The ultimate resolution of these examinations could be substantially different from the Company’s estimate of any potential associated liabilities, and any resulting adjustments could have a material adverse affect on Emulex’s tax provision, net income/(loss) and cash flows.

	Average market price of common stock	5.43			7.77
	The antidilutive stock options and unvested stock were excluded from the computation of diluted net loss per share due to the net losses in the periods presented.
	As the principal amount of the Convertible Senior Notes (Note 8) will be settled in cash upon conversion, only the conversion spread relating to the Convertible Senior Notes will be included in the calculation of diluted net income per common share. As such, the Convertible Senior Notes will have no impact on diluted net income per common share until the price of the Company's common stock exceeds the conversion price (initially $10.30, subject to adjustments) of the Convertible Senior Notes. When the market price of the Company's stock exceeds the conversion price, the effect of the additional shares that may be issued upon conversion of the Convertible Senior Notes will be included in the diluted net income per common share calculation. During the three month period ended September 28, 2014, there were no anti-dilutive shares resulting from the Convertible Senior Notes as the price of the Company's common stock did not exceed the conversion price.

	Emulex has two reportable business segments, Connectivity (formerly referred to as Networking) and Visibility. The Visibility segment was formed as a result of the acquisition of Endace on February 26, 2013. The Connectivity segment includes the operating results of Network Connectivity Products (NCP) and Storage Connectivity and Other Products (SCOP). The Visibility segment includes the operating results of Network Visibility Products (NVP) resulting from the Endace acquisition.
	The chief operating decision maker measures the performance of each of these segments based on adjusted operating results. The operating results of each segment are adjusted for certain expenses and reflect an additional way of viewing aspects of the Company's operations, factors and trends. However, these measures should be considered as a supplement to, and not as a substitute for, or superior to, the corresponding measures calculated in accordance with accounting principles generally accepted in the United States.
