Atmel Corporation NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)
Note 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation
These unaudited interim condensed consolidated financial statements reflect all normal recurring adjustments which are, in the opinion of management, necessary to state fairly, in all material respects, the financial position of Atmel Corporation (the Company or Atmel) and its subsidiaries as of March 31, 2012 and the results of operations, comprehensive income and cash flows for the three months ended March 31, 2012 and 2011. All intercompany balances have been eliminated. Because all of the disclosures required by U.S. generally accepted accounting principles are not included, as permitted by the rules of the Securities and Exchange Commission (the SEC), these interim condensed consolidated financial statements should be read in conjunction with the audited condensed consolidated financial statements and accompanying notes included in the Companys Annual Report on Form 10-K for the year ended December 31, 2011. The December 31, 2011 year-end condensed balance sheet data was derived from the Companys audited consolidated financial statements, which are included in the Companys Annual Report on Form 10-K for the year ended December 31, 2011 and does not include all of the disclosures required by U.S. generally accepted accounting principles. The condensed consolidated statements of operations for the periods presented are not necessarily indicative of results to be expected for any future period, or for the entire year.
The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates in these financial statements include provisions for excess and obsolete inventory, sales return reserves and allowances, stock-based compensation expense, allowances for doubtful accounts receivable, warranty reserves, estimates for useful lives associated with long-lived assets, recoverability of goodwill and intangible assets, restructuring (credits) charges, liabilities for uncertain tax positions and deferred tax asset valuation allowances. Actual results could differ materially from those estimates.
Inventories
Inventories are stated at the lower of cost (on a first-in, first-out basis) or market. Market is based on estimated net realizable value. Determining market value of inventories involves numerous judgments, including estimating average selling prices and sales volumes for future periods. The Company establishes provisions for lower of cost or market and excess and obsolescence write-downs, which are charged to cost of revenue. The Company makes a determination regarding excess and obsolete inventory on a quarterly basis, which determination requires an estimation of the future demand for the Companys products, which involves an analysis of historical and forecasted sales levels by product, competitiveness of product offerings, market conditions, product lifecycles, as well as other factors. Excess and obsolete inventory write-downs are recorded when the inventory on hand exceeds managements estimate of future demand for each product and are charged to cost of revenue.
The Companys inventories include parts that have a potential for rapid technological obsolescence and are sold in a highly competitive industry. The Company writes-down inventory that is considered excess or obsolete. When the Company recognizes loss on such inventory, it establishes a new, lower-cost basis for that inventory, and subsequent changes in facts and circumstances will not result in the restoration or increase in that newly established cost basis. If inventory with a lower-cost basis is subsequently sold, it will result in higher gross margin for the products making up that inventory.
Inventories are comprised of the following:
Grant Recognition
From time to time, the Company receives economic incentive grants and allowances from European governments, agencies and research organizations targeted at increasing employment at specific locations. The subsidy grant agreements typically contain economic incentive, headcount, capital and research and development expenditures and other covenants that must be met to receive and retain grant benefits. Noncompliance with the conditions of the grants could result in the forfeiture of all or a portion of any future amounts to be received, as well as the repayment of all or a portion of amounts received. In addition, the Company may need to record charges to reverse grant benefits recorded in prior periods as a result of changes to its plans for headcount, project spending, or capital investment at any of these specific locations. If the Company is unable to comply with any of the covenants in the grant agreements, the Company may face adverse actions from the government agencies providing the grants. If the Company were required to repay grant benefits, its results of operations and financial position could be materially adversely affected by the amount of such repayments.
In March 2012, a ministerial decision of the Greek government was executed related to outstanding state grants previously made to a Greek subsidiary of the Company. Based on the execution of the ministerial decision and the subsequent publication of that decision by the Greek government, the Company determined that it would not be required to repay the full amount of the grant made by the Greek government to the Companys Greek subsidiary. As a result, the Company recognized a benefit of $10.7 million in its results for the three month period ended March 31, 2012 resulting from the reversal of a reserve previously established for that grant.
Recent Accounting Pronouncements
In June 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-05, Comprehensive Income (ASC Topic 220) Presentation of Comprehensive Income. The amendments from this update will result in more converged guidance on how comprehensive income is presented under U.S. GAAP and International Financial Reporting Standards (IFRS). With this update to ASC 220, an entity has the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In either option, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. The amendments in this update do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income, nor does it affect how earnings per share is calculated or presented. Previously, U.S. GAAP allowed reporting entities three alternatives for presenting other comprehensive income and its components in financial statements. One such alternative was to present the components of other comprehensive income as part of the statement of changes in stockholders equity. This ASU eliminates that option. The amended guidance also requires presentation of adjustments for items that are reclassified from other comprehensive income to net income in the statement where the components of net income and the components of other comprehensive income are presented. The amendments in this ASU should be applied retrospectively. For public entities, the amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. In December 2011 the FASB decided to defer the requirement to present reclassifications of other comprehensive income on the face of the income statement. The Companys adoption of this guidance as of January 1, 2012 did not have a material impact on its condensed consolidated financial position, results of operations or cash flows.
Note 2 INVESTMENTS
Investments at March 31, 2012 and December 31, 2011 are primarily comprised of corporate equity securities, U.S. and foreign corporate debt securities, guaranteed variable annuities and auction-rate securities.
All marketable securities are deemed by management to be available-for-sale and are reported at fair value, with the exception of certain auction-rate securities as described below. Net unrealized gains and losses that are deemed to be temporary are reported within stockholders equity on the Companys condensed consolidated balance sheets as a component of accumulated other comprehensive income. Unrealized losses that are deemed to be other than temporary are recorded in the condensed consolidated statement of operations in the period such determination is made. Gross realized gains or losses are recorded based on the specific identification method. For the three months ended March 31, 2012 and 2011, the Companys gross realized gains or losses on short-term investments were insignificant. The Companys investments are further detailed in the table below:
In September 2010, in connection with the sale of the Companys smart card business in France to INSIDE Secure (INSIDE), the Company received an equity interest in INSIDE, which was privately-held at the time of the investment. In February 2012, INSIDE successfully completed an initial public offering on the NYSE Euronext stock exchange in Paris. As a result of that public offering, the Company reclassified its investment in INSIDE to short-term investments from other assets and now accounts for this investment as available for sale. Accordingly, an unrealized gain of $4.8 million was recorded in accumulated other comprehensive income in the three months ended March 31, 2012.
For the three months ended March 31, 2012, auctions for auction-rate securities held by the Company have continued to fail and as a result these securities continued to be illiquid. The Company concluded that $2.2 million (adjusted cost) of these securities are unlikely to be liquidated within the next twelve months and classified these securities as long-term investments, which are included in other assets on the condensed consolidated balance sheets.
Contractual maturities (at adjusted cost) of available-for-sale debt securities as of March 31, 2012, were as follows:
Atmel has classified all investments with original maturity dates of 90 days or more as short-term as it has the ability and intent to redeem them within the year, with the exception of the Companys remaining auction-rate securities, which have been classified as long-term investments and included in other assets on the condensed consolidated balance sheets.
Note 3 FAIR VALUE OF ASSETS AND LIABILITIES
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). This accounting standard establishes a consistent framework for measuring fair value and expands disclosure requirements about fair value measurements. This accounting standard, among other things, requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.
The table below presents the balances of investments measured at fair value on a recurring basis at March 31, 2012:
The table below presents the balances of investments measured at fair value on a recurring basis at December 31, 2011:
The Companys investments, with the exception of auction-rate securities, are classified within Level 1 or Level 2 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. The types of instruments valued based on quoted market prices in active markets include most U.S. government and agency securities and money market securities. Such instruments are generally classified within Level 1 of the fair value hierarchy. The types of instruments valued based on other observable inputs include corporate debt securities and other obligations. Such instruments are generally classified within Level 2 of the fair value hierarchy.
Auction-rate securities are classified within Level 3 because significant assumptions for such securities are not observable in the market. The total amount of assets measured using Level 3 valuation methodologies represented less than 1% of total assets as of March 31, 2012.
There were no changes in Level 3 assets measured at fair value on a recurring basis for the three months ended March 31, 2012 and the year ended December 31, 2011.
Note 4 STOCKHOLDERS EQUITY
Stock-Based Compensation
The following table summarizes the distribution of stock-based compensation expense by function for the three months ended March 31, 2012 and 2011:
Stock Options, Restricted Stock Units and Employee Stock Purchase Plan
In May 2005, Atmels stockholders initially approved Atmels 2005 Stock Plan (as amended, the 2005 Stock Plan). As of March 31, 2012, 133.0 million shares were authorized for issuance under the 2005 Stock Plan. Under the 2005 Stock Plan, Atmel may issue common stock directly, grant options to purchase common stock or grant restricted stock units payable in common stock to employees, consultants and directors of Atmel. Options, which generally vest over four years, are granted at fair market value on the date of the grant and generally expire ten years from that date.
Activity under Atmels 2005 Stock Plan is set forth below:
Restricted stock units are granted from the pool of options available for grant. As the result of an amendment and restatement of the 2005 Stock Plan in May 2011, every share underlying restricted stock, restricted stock units (including performance based restricted stock units), and stock purchase rights issued on or after May 18, 2011 (the date on which the amendment and restatement became effective) is counted against the numerical limit for options available for grant as 1.61 shares in the table above, except that restricted stock, restricted stock units (including performance based restricted stock units), and stock purchase rights issued prior to May 18, 2011, continue to be governed by an earlier amendment to the 2005 Stock Plan that provided for a numerical limit of 1.78 shares. If shares issued pursuant to any restricted stock, restricted stock unit, and stock purchase right agreements granted on or after May 18, 2011 are cancelled, forfeited or repurchased by the Company and would otherwise return to the 2005 Stock Plan, 1.61 times the number of those shares will return to the 2005 Stock Plan and will again become available for issuance. The Company issued 8.0 million shares of restricted stock units from May 18, 2011 to March 31, 2012 (net of cancellations) resulting in a reduction, based on a 1.61 to 1.0 ratio, of 12.8 million shares available for grant under the 2005 Stock Plan from May 18, 2011 to March 31, 2012. As of March 31, 2012, there were 16.8 million shares available for issuance under the 2005 Stock Plan, or 10.4 million after giving effect to the 1.61 to 1.0 ratio applicable under the 2005 Stock Plan for issuances made on after May 18, 2011.
Restricted Stock Units
Activity related to restricted stock units is set forth below:
In the three months ended March 31, 2012, 1.2 million restricted stock units vested, including 0.5 million units withheld for taxes. These vested restricted stock units had a weighted-average fair value of $10.27 per share on the vesting dates for the three months ended March 31, 2012. As of March 31, 2012, total unearned stock-based compensation related to unvested restricted stock units previously granted (including performance-based restricted stock units) was approximately $163.3 million, excluding forfeitures, and is expected to be recognized over a weighted-average period of 2.65 years.
In the three months ended March 31, 2011, 0.9 million restricted stock units vested, including 0.3 million units withheld for taxes. These vested restricted stock units had a weighted-average fair value of $15.92 per share on the vesting dates for the quarter ended March 31, 2011. As of March 31, 2011, total unearned stock- based compensation related to nonvested restricted stock units previously granted (including performance-based restricted stock units) was approximately $119.0 million, excluding forfeitures, and is expected to be recognized over a weighted-average period of 3.11 years.
Until restricted stock units are vested, they do not have the voting rights of common stock and the shares underlying such restricted stock units are not considered issued and outstanding. Upon vesting of restricted stock units, shares withheld by the Company to pay taxes are retired.
Performance-Based Restricted Stock Units
In May 2011, the Company adopted the 2011 Long-Term Performance Based Incentive Plan (the 2011 Plan), which provides for the grant of restricted stock units to eligible employees; vesting of these restricted stock units is subject to the satisfaction of performance metrics tied to, revenue growth and operating margin over the designated performance periods. The performance periods for the 2011 Plan run from January 1, 2011 through December 31, 2013, consisting of three one year performance periods (calendar years 2011, 2012 and 2013) and a three year cumulative performance period. The Company issued 0.2 million performance-based restricted stock units in the three months ended March 31, 2012. The Company recorded total stock-based compensation expense related to performance-based restricted stock units of $4.3 million under the 2011 Plan in the three months ended March 31, 2012.
The 2011 Plan performance metrics include revenue growth rankings for the Company relative to a semiconductor peer group or a microcontroller peer group, as determined by the Compensation Committee. In addition, in order for a participant to receive credit for a performance period the Company must achieve a minimum operating margin during such performance period, measured on a pro forma basis, subject to adjustment by the Compensation Committee. Management evaluates, on a quarterly basis, the likelihood of the Company meeting its performance metrics in determining stock-based compensation expense for performance share plans.
The Company recorded total stock based compensation expense related to performance based restricted stock units of $6.5 million under the Companys 2008 Incentive Plan (the 2008 Plan) in the three months ended March 31, 2011.
Stock Option Awards
No options were granted in the three months ended March 31, 2012 or 2011.
As of March 31, 2012, total unearned compensation expense related to unvested stock options was approximately $4.0 million, excluding forfeitures, and is expected to be recognized over a weighted-average period of 1.48 years.
Employee Stock Purchase Plan
Under the 1991 Employee Stock Purchase Plan (1991 ESPP) and 2010 Employee Stock Purchase Plan (2010 ESPP and, together with the 1991 ESPP, the Companys ESPPs), qualified employees are entitled to purchase shares of Atmels common stock at the lower of 85% of the fair market value of the common stock at the date of commencement of the six-month offering period or at 85% of the fair market value on the last day of the offering period. Purchases are limited to 10% of an employees eligible compensation. There were 0.7 million shares purchased under the 2010 ESPP for the three months ended March 31, 2012 at an average price per share of $8.33. Of the 25.0 million shares authorized for issuance under the 2010 ESPP, 23.6 million shares were available for issuance at March 31, 2012. There were 0.8 million shares purchased under the 1991 ESPP for the three months ended March 31, 2011, at an average price per share of $4.85. The remaining 1.9 million shares available under the 1991 plan expired in the three months ended March 31, 2011.
The fair value of each purchase under the Companys ESPPs is estimated on the date of the beginning of the offering period using the Black-Scholes option pricing model. The following assumptions were utilized to determine the fair value of the Companys ESPPs shares:
The weighted-average fair value of the rights to purchase shares under the Companys ESPPs for purchase periods beginning in the three months ended March 31, 2012 and 2011 was $2.27 and $3.16, respectively. Cash proceeds from the issuance of shares under the Companys ESPPs were $5.4 million and $4.1 million for the three months ended March 31, 2012 and 2011, respectively.
Common Stock Repurchase Program
Over the past several years, Atmels Board of Directors authorized $500.0 million of funding for the Companys stock repurchase program. The repurchase program does not have an expiration date, and the number of shares repurchased and the timing of repurchases are based on the level of the Companys cash balances, general business and market conditions, regulatory requirements, and other factors, including alternative investment opportunities. As of March 31, 2012, $10.6 million remained available for repurchase under this program.
During the three months ended March 31, 2012 and 2011, Atmel repurchased 9.5 million and 5.7 million shares, respectively, of its common stock on the open market at an average repurchase price of $10.18 and $14.93 per share, excluding commission, and subsequently retired those shares. Common stock and additional paid-in capital were reduced by $96.2 million and $85.1 million, excluding commission, for the three months ended March 31, 2012 and 2011, respectively, as a result of the stock repurchases.
Note 5 ACCUMULATED OTHER COMPREHENSIVE INCOME
Comprehensive income is defined as a change in equity of a company during a period, from transactions and other events and circumstances excluding transactions resulting from investments by owners and distributions to owners. The primary difference between net income and comprehensive income for the Company arises from foreign currency translation adjustments, actuarial gains related to defined benefit pension plans and net unrealized gains on investments. The components of accumulated other comprehensive income at March 31, 2012 and 2011, net of tax, are as follows:
Note 6 COMMITMENTS AND CONTINGENCIES
Commitments
Indemnification
As is customary in the Companys industry, the Companys standard contracts provide remedies to its customers, such as defense, settlement, or payment of judgment for intellectual property claims related to the use of the Companys products. From time to time, the Company will indemnify customers against combinations of loss, expense, or liability arising from various trigger events related to the sale and the use of the Companys products and services, usually up to a specified maximum amount. In addition, as permitted under state laws in the United States, the Company has entered into indemnification agreements with its officers and directors and certain employees, and the Companys bylaws permit the indemnification of the Companys agents. In the Companys experience, the estimated fair value of the liability is not material.
Purchase Commitments
At March 31, 2012, the Company had certain commitments which were not included on the condensed consolidated balance sheet at that date. These include outstanding capital purchase commitments of approximately $1.4 million, wafer purchase commitments of approximately $19.2 million under the Companys supply agreement with Telefunken Semiconductors GmbH & Co. KG and wafer purchase commitments of approximately $180.6 million under the Companys supply agreement with LFoundry Rousset SAS (LFoundry Rousset).
On April 18, 2012, the Company amended its wafer purchase commitments with LFoundry Rousset, which reduced those commitments to approximately $112.0 million as of April 18, 2012.
Contingencies
Legal Proceedings
The Company is party to various legal proceedings. Management currently believes that the ultimate outcome of these proceedings, individually and in the aggregate, will not have a material adverse effect on its financial position, results of operations and statement of cash flows. If, however, an unfavorable ruling were to occur in any of the legal proceedings described below or other legal proceedings that were not deemed material as of March 31, 2012, there exists the possibility of a material adverse effect on the Companys financial position, results of operations and cash flows. The Company has accrued for losses related to the litigation described below that it considers probable and for which the loss can be reasonably estimated. In the event that a probable loss cannot be reasonably estimated, it has not accrued for such losses. As the Company continues to monitor these matters; its determination could change, however, and the Company may decide, at some future date, to establish an appropriate reserve. With respect to each of the matters below, except where noted otherwise, management has determined a potential loss is not probable at this time and, accordingly, no amount has been accrued at March 31, 2012. Management makes a determination as to when a potential loss is reasonably possible based on relevant accounting literature and then includes appropriate disclosure of the contingency. Except as otherwise noted, management does not believe that the amount of loss or a range of possible losses is reasonably estimable.
Infineon Litigation. On April 11, 2011, Infineon Technologies A.G. and Infineon Technologies North America Corporation (collectively, Infineon) filed a patent infringement lawsuit against the Company in the United States District Court for the District of Delaware. Infineon alleges that the Company is infringing 11 Infineon patents and seeks a declaration that three of the Companys patents are either invalid or not infringed. On July 5, 2011, the Company answered
Infineons complaint, and filed counterclaims seeking a declaration that each of the 11 asserted Infineon patents is invalid and not infringed. The Company also counterclaimed for infringement of six of the Companys patents and breach of contract related to Infineons breach of a confidentiality agreement. On July 29, 2011, Infineon answered these counterclaims and sought a declaration that the Companys patents were either invalid or not infringed. On March 13, 2012, the Company filed amended counterclaims that alleged Infineons infringement of four additional Atmel patents. On March 31, 2012, Infineon answered these counterclaims and sought a declaration that the Companys newly asserted patents were either invalid or not infringed. Trial of these matters currently is scheduled to commence in early 2014. The Company intends to prosecute its claims and defend vigorously against Infineons claims.
From time to time, the Company is notified of claims that its products may infringe patents, or other intellectual property, issued to other parties. The Company periodically receives demands for indemnification from its customers with respect to intellectual property matters. The Company also periodically receives claims relating to the quality of its products, including claims for additional labor costs, costs for replacing defective parts, reimbursement to customers for damages incurred in correcting their defective products, costs for product recalls or other damages. Receipt of these claims and requests occurs in the ordinary course of the Companys business, and the Company responds based on the specific circumstances of each event. The Company undertakes an accrual for losses relating to those types of claims when it considers those losses probable and when a reasonable estimate of loss can be determined.
Other Contingencies
In October 2008, officials of the European Union Commission (the Commission) conducted an inspection at the offices of one of the Companys French subsidiaries. The Company was informed that the Commission was seeking evidence of potential violations by Atmel or its subsidiaries of the European Unions competition laws in connection with the Commissions investigation of suppliers of integrated circuits for smart cards. On September 21, 2009 and October 27, 2009, the Commission requested additional information from the Company, and the Company responded to the Commissions requests. The Company continues to cooperate with the Commissions investigation and has not received any specific findings, monetary demand or judgment through the date of filing this Form 10-Q. As a result, the Company has not recorded any provision in its financial statements related to this matter.
Product Warranties
The Company accrues for warranty costs based on historical trends of product failure rates and the expected material and labor costs to provide warranty services. The Companys products are generally covered by a warranty typically ranging from 30 days to two years.
The following table summarizes the activity related to the product warranty liability for the three months ended March 31, 2012 and 2011.
Product warranty liability is included in accrued and other liabilities on the condensed consolidated balance sheets.
Guarantees
During the ordinary course of business, the Company provides standby letters of credit or other guarantee instruments to certain parties as required for certain transactions initiated by either the Company or its subsidiaries. The Company has not recorded any liability in connection with these guarantee arrangements. Based on historical experience and information currently available, the Company believes it will not be required to make any payments under these guarantee arrangements.
Note 7 INCOME TAXES
The Company estimates its annual effective tax rate at the end of each quarter. In making these estimates, the Company considers, among other things, annual pre-tax income, the geographic mix of pre-tax income and the application and interpretations of tax laws, treaties and judicial developments, in collaboration with its tax advisors, and possible outcomes of audits.
The following table presents the provision for income taxes and the effective tax rates:
The Companys effective tax rate for the three months ended March 31, 2012 was lower than the statutory federal income tax rate of 35%. The Companys tax provision was lower than it otherwise would have been due to income recognized in lower tax rate jurisdictions as a result of a reorganization of its subsidiary structure implemented on January 1, 2011 and the recognition of certain refundable R&D credits. The effective tax rate for the three months ended March 31, 2011 was lower than the statutory federal income tax rate of 35% primarily due to tax rate benefits of certain earnings from the Companys operations in jurisdictions with lower tax rates than the US. These benefits result primarily from the January 1, 2011 reorganization of its subsidiary structure.
The Company files U.S., state and foreign income tax returns in jurisdictions with varying statutes of limitations. The 2001 through 2011 tax years generally remain subject to examination by federal and most state tax authorities. For significant foreign jurisdictions, the 2001 through 2011 tax years generally remain subject to examination by their respective tax authorities.
Currently, the Company has tax audits in progress in various foreign jurisdictions. To the extent the final tax liabilities are different from the amounts originally accrued, the increases or decreases are recorded as income tax expense or benefit in the consolidated statements of operations. While the Company believes that the resolution of these audits will not have a material adverse impact on the Companys results of operations, the outcome is subject to uncertainty.
At March 31, 2012 and December 31, 2011, the Company had $23.9 million and $25.2 million of unrecognized tax benefits, respectively, which, if recognized, would affect the effective tax rate. Also at March 31, 2012 and December 31, 2011, the Company had $43.5 million and $42.8 million of unrecognized tax benefits, respectively, which, if recognized, would result in adjustments to other tax accounts, primarily deferred tax assets.
Increases or decreases in unrecognizable tax benefits could occur over the next 12 months due to tax law changes, unrecognized tax benefits established in the normal course of business, or due to the conclusion of ongoing tax audits in various jurisdictions around the world. While it is reasonably possible that some or all of these events may occur within the next 12 months, the Company is not able to accurately estimate the range of any potential change in unrecognized tax benefits that would result from the occurrence of such events. The calculation of unrecognized tax benefits involves dealing with uncertainties in the application of complex global tax regulations. The Company regularly assesses its tax positions in light of legislative, bilateral tax treaty, regulatory and judicial developments in the countries in which the Company does business.
Note 8 PENSION PLANS
The Company sponsors defined benefit pension plans that cover substantially all of its French and German employees. Plan benefits are provided in accordance with local statutory requirements. Benefits are based on years of service and employee compensation levels. The plans are unfunded. Pension liabilities and charges to expense are based upon various assumptions, updated quarterly, including discount rates, future salary increases, employee turnover, and mortality rates.
The Companys French pension plan provides for termination benefits paid to covered French employees only at retirement, and consists of approximately one to five months of salary. The Companys German pension plan provides for defined benefit payouts for covered German employees following retirement.
The aggregate net pension expense relating to these two plans are as follows:
Settlement and other related gain of $0.7 million for the three months ended March 31, 2011 related to restructuring activity in the Companys Rousset, France operations initiated in the second quarter of 2010.
The Companys net pension cost for 2012 is expected to be approximately $2.8 million. Cash funding for benefits paid was insignificant for the three months ended March 31, 2012. Cash funding for benefits to be paid for 2012 is expected to be approximately $0.3 million.
Note 9 OPERATING AND GEOGRAPHICAL SEGMENTS
The Company designs, develops, manufactures and sells semiconductor integrated circuit products. The Companys segments represent managements view of the Companys businesses and how it allocates Company resources and measures performance of its major components. Each segment consists of product families with similar requirements for design, development and marketing. Each segment requires different design, development and marketing resources to produce and sell products. Atmels four reportable segments are as follows:
· Microcontrollers. This segment includes Atmels capacitive touch products, including maXTouch and QTouch, AVR 8-bit and 32-bit products, ARM-based products and Atmels 8051 8-bit products.
· Nonvolatile Memories. This segment includes serial interface electrically erasable programmable read-only memory (SEEPROM), serial and parallel interface Flash memory, and electrically erasable programmable read-only memory (EEPROM) and erasable programmable ready-only memory (EPROM) devices. This segment also includes products with military and aerospace applications.
· Radio Frequency (RF) and Automotive. This segment includes automotive electronics, wireless and wired devices for industrial, consumer and automotive applications and foundry services for radio frequency products designed for mobile telecommunications markets.
· Application Specific Integrated Circuit (ASIC). This segment includes custom application specific integrated circuits designed to meet specialized single-customer requirements for their high performance devices in a broad variety of specific applications, including products that provide hardware security for embedded digital systems, products with military and aerospace applications and application specific standard products for space applications, power management and secure cryptographic memory products.
The Company evaluates segment performance based on revenue and income or loss from operations excluding acquisition-related charges, restructuring charges, credit from reserved grant income and gain on sale of assets. Interest and other (expenses) income, net, foreign exchange gains and losses and income taxes are not measured by operating segment. Because the Companys segments reflect the manner in which management reviews its business, they necessarily involve subjective judgments that management believes are reasonable in light of the circumstances under which they are made. These judgments may change over time or may be modified to reflect new facts or circumstances. Segments may also be changed or modified to reflect products, technologies or applications that are newly created, or that change over time, or
other business conditions that evolve, each of which may result in reassessing specific segments and the elements included within each of those segments. Recent events may affect the manner in which the Company presents segments in the future.
Segments are defined by the products they design and sell. They do not make sales to each other. The Companys net revenue and segment income from operations for each reportable segment for the three months ended March 31, 2012 and 2011 are as follows:
Information about Reportable Segments
The Company does not allocate assets by segment, as management does not use asset information to measure or evaluate a segments performance.
Reconciliation of Segment Information to Condensed Consolidated Statements of Operations
Geographic sources of revenue were as follows:
Net revenue is attributed to countries based on the locations to where the Company ships.
One customer accounted for 15% of net revenue in the three months ended March 31, 2012. No single customer accounted for more than 10% of net revenue in the three months ended March 31, 2011. Three distributors accounted for 15%, 11% and 11%, respectively, of accounts receivable at March 31, 2012. Two distributors accounted for 15% and 14%, respectively, of accounts receivable at December 31, 2011.
Locations of long-lived assets as of March 31, 2012 and December 31, 2011 were as follows:
Excluded from the table above are auction-rate securities of $2.3 million as of both March 31, 2012 and December 31, 2011, which are included in other assets on the condensed consolidated balance sheets. Also excluded from the table above as of March 31, 2012 and December 31, 2011 are goodwill of $67.4 million and $67.7 million, respectively, intangible assets, net of $18.3 million and $21.0 million, respectively and deferred income tax assets of $119.1 million and $121.4 million, respectively.
Note 10 GAIN ON SALE OF ASSETS
DREAM
On February 15, 2011, the Company sold its DREAM business, including its French subsidiary, Digital Research in Electronics, Acoustics and Music SAS (DREAM), which sold custom-designed ASIC chips for karaoke and other entertainment machines, for $2.3 million. The Company recorded a gain of $1.9 million, which is reflected in gain on sale of assets in the condensed consolidated statements of operations.
Rousset
In connection with the sale of its manufacturing operations in France to LFoundry GmbH, the Company retained a minority equity interest in LFoundry Rousset, the entity that holds those manufacturing operations. This equity interest provides limited protective rights to the Company, but no decision-making rights that are significant to the economic performance of LFoundry Rousset. The Company is shielded from economic losses and does not participate fully in LFoundry Roussets residual economics; accordingly, the Company has concluded that its equity interest in LFoundry Rousset is an interest in a variable interest entity (VIE). At the time of the sale, the Company identified LFoundry Roussets significant activities and the parties that have the power to direct them, determined LFoundry Roussets equity, profit and loss participation, and reviewed LFoundry Roussets funding and operating agreements. Based on the above analysis, the Company determined that it is not the primary beneficiary of LFoundry Rousset and hence does not consolidate LFoundry Rousset in its financial statements. The Companys maximum exposure related to LFoundry Rousset is not expected to be significantly in excess of the amounts recorded and it does not intend to provide any support to LFoundry Rousset, financial or otherwise.
Note 11 RESTRUCTURING CHARGES
The following table summarizes the activity related to the accrual for restructuring charges detailed by event for the three months ended March 31, 2012 and 2011.
2011 Restructuring Charges
For the three months ended March 31, 2011, the Company began implementing cost reduction activities, primarily targeting research and development labor costs. The Company incurred restructuring charges of $21.2 million related to severance costs resulting from involuntary termination of employees at the Companys subsidiary located in Rousset, France. Employee severance costs were recorded in accordance with the accounting standard related to costs associated with exit or disposal activities. The Company paid $0.7 million related to employee termination costs for the three months ended March 31, 2012.
Note 12 NET INCOME PER SHARE
Basic net income per share is calculated by using the weighted-average number of common shares outstanding during that period. Diluted net income per share is calculated giving effect to all dilutive potential common shares that were outstanding during the period. Dilutive potential common shares consist of incremental common shares issuable upon exercise of stock options, upon vesting of restricted stock units, contingent issuable shares for all periods and accrued issuance of shares under employee stock purchase plan.
A reconciliation of the numerator and denominator of basic and diluted net income per share is provided as follows:
The following table summarizes securities which were not included in the Weighted-average shares diluted used for calculation of diluted net income per share, as their effect would have been anti-dilutive:

OVERVIEW
We are one of the worlds leading designers, developers and suppliers of microcontrollers, which are self-contained computers-on-a-chip. Microcontrollers are generally less expensive, consume less power and offer enhanced programming capabilities compared to traditional microprocessors. Our microcontrollers and related products are used today in many of the worlds leading smart phones, tablet devices and other consumer and industrial electronics to provide core functionality for touch sensing, security, wireless and communication applications and battery management. We offer an extensive portfolio of capacitive touch products that integrate our microcontrollers with fundamental touch-focused intellectual property, or IP, we have developed and we continue to leverage our market and technology advantages to expand our product portfolio within the touch-related eco-system. Toward that end, and as a natural extension of our touch controller business, we recently announced our XSense product, a new type of touch sensor based on proprietary metal mesh technologies. We also design and sell products that are complementary to our microcontroller business, including nonvolatile memory and flash memory products, radio frequency and mixed-signal components and application specific integrated circuits. Our semiconductors also enable applications in many other fields, such as smart-metering for utility monitoring and billing, buttons, sliders and wheels found on the touch panels of appliances, various aerospace, industrial, and military products and systems, and electronic-based automotive components, such as keyless ignition, access, engine control, lighting and entertainment systems, for standard and hybrid vehicles. Over the past several years, we transitioned our business to a fab-lite model, lowering our fixed costs and capital investment requirements, and we currently own and operate one manufacturing facility in Colorado Springs, Colorado.
During the three months ended March 31, 2012, we repurchased 9.5 million shares of our common stock in the open market and subsequently retired those shares under our existing stock repurchase program. As of March 31, 2012, $10.6 million remained available for repurchase under this program. On April 30, 2012, our Board of Directors authorized an additional $200 million for this program.
RESULTS OF OPERATIONS
Net Revenue
Our net revenue totaled $357.8 million for the three months ended March 31, 2012, a decrease of 22%, or $103.6 million, from $461.4 million in net revenue for the three months ended March 31, 2011. Revenue decreased primarily
due to reduced sales of our products as a result of difficult global economic conditions that adversely affected the industrial and consumer markets into which our products are sold. In the three months ended March 31, 2012, our distributors, which accounted for approximately 50% of our sales in that period, reduced their aggregate inventories of our products by 19% as compared to the three months ended December 31, 2011.
Included in revenue in the three months ended March 31, 2012, is $7.6 million of payments made from an Asian distributor recognized on a cash basis, which had been deferred at December 31, 2011, and not included in our net revenue at year end.
Net revenue denominated in Euros was 21% and 23% for the three months ended March 31, 2012 and 2011, respectively. Average exchange rates utilized to translate foreign currency revenue and expenses in Euros were approximately 1.31 and 1.34 Euros to the dollar for the three months ended March 31, 2012 and 2011, respectively.
Net Revenue By Operating Segment
Our net revenue by operating segment is summarized as follows:
Microcontroller
Microcontroller segment net revenue decreased 26% to $217.8 million for the three months ended March 31, 2012 from $293.8 million for the three months ended March 31, 2011. Revenue decreased primarily due to decreased sales of our 8-bit and 32-bit microcontrollers as a result of reduced demand in the industrial end markets. Microcontroller net revenue represented 61% and 64% of total net revenue for the three months ended March 31, 2012 and 2011, respectively.
Nonvolatile Memory
Nonvolatile Memory segment net revenue decreased 25% to $47.7 million for the three months ended March 31, 2012 from $63.4 million for the three months ended March 31, 2011. The decline in our memory business resulted primarily from reduced market demand, a weaker pricing environment and the end of life for several flash products, including Serial EE and Serial Flash products, which saw revenue decrease by 18% and 49%, respectively.
RF and Automotive
RF and Automotive segment net revenue decreased 14% to $43.5 million for the three months ended March 31, 2012 from $50.9 million for the three months ended March 31, 2011. This decrease was primarily related to continued decline in demand for our non-automotive products within this segment during the first three months of 2012 partially offset by an increase of 11% in net revenue from sales of our high voltage products, which are used primarily for automotive airbag controllers.
ASIC
ASIC segment net revenue decreased 9% to $48.8 million for the three months ended March 31, 2012 from $53.4 million for the three months ended March 31, 2011. Our military and aerospace business revenue, which is approximately 32% of overall ASIC revenue, decreased approximately 14% during the three months ended March 31, 2012 compared to the three months ended March 31, 2011.
Net Revenue by Geographic Area
Our net revenue by geographic area for the three months ended March 31, 2012, compared to the same period in 2011, is summarized as follows. Revenue is attributed to countries based on the location to which we ship. See Note 9 of Notes to Condensed Consolidated Financial Statements for further discussion.
* Primarily includes South Africa, and Central and South America
Net revenue outside the United States accounted for 87% and 85% of our net revenue for the three months ended March 31, 2012 and 2011, respectively.
Our net revenue in Asia decreased $63.9 million, or 24%, for the three months ended March 31, 2012, compared to the same period in 2011. The decrease in this region for the three months ended March 31, 2012, compared to the three months ended March 31, 2011 was primarily due to lower shipments of our microcontroller products as a result of difficult global economic conditions that adversely affected the industrial and consumer markets into which these products are sold. In the three months ended March 31, 2012, our distributors in Asia reduced their inventory of our products by 18% as compared to the three months ended December 31, 2011. Net revenue for the Asia region was 57% of total net revenue for the three months ended March 31, 2012 compared to 58% of total net revenue for the three months ended March 31, 2011.
Our net revenue in Europe decreased $20.4 million, or 17%, for the three months ended March 31, 2012, compared to the three months ended March 31, 2011. The decrease in this region for the three months ended March 31, 2012, compared to the three months ended March 31, 2011 was primarily a result of the continued decline in industrial markets. Net revenue for the Europe region was 28% of total net revenue for the three months ended March 31, 2012 compared to 26% of total net revenue for the three months ended March 31, 2011.
Our net revenue in the United States decreased by $21.3 million, or 31%, for the three months ended March 31, 2012, compared to the three months ended March 31, 2011. This decrease resulted primarily from reduced demand for smart metering and consumer-based products. Net revenue for the United States region was 13% of total net revenue for the three months ended March 31, 2012, compared to 15% of total net revenue for the three months ended March 31, 2011.
Revenue and Costs Impact from Changes to Foreign Exchange Rates
Changes in foreign exchange rates have historically had an effect on our net revenue and operating costs. Net revenue denominated in foreign currencies was 21% and 23% of our total net revenue for the three months ended March 31, 2012 and 2011, respectively. Costs denominated in foreign currencies were 18% and 20% of our total costs for the three months ended March 31, 2012 and 2011, respectively.
Net revenue denominated in Euros was 21% and 23% for the three months ended March 31, 2012 and 2011, respectively. Costs denominated in Euros were 11% and 14% of our total costs for the three months ended March 31, 2012 and 2011, respectively.
Average exchange rates utilized to translate foreign currency revenue and expenses in Euros were approximately 1.31 and 1.34 Euros to the dollar for the three months ended March 31, 2012 and 2011, respectively.
For the three months ended March 31, 2012, changes in foreign exchange rates had an unfavorable overall effect on our operating results. Our net revenue for the three months ended March 31, 2012 would have been approximately $1.9 million higher had the average exchange rate in the current year remained the same as the average rate in effect for the
three months ended March 31, 2011. In addition, in the three months ended March 31, 2012, our operating expenses would have been approximately $1.2 million higher. The net effect, had average foreign currency rates remained the same during the three months ended March 31, 2012 as in the same period in 2011, would have been that income from operations would have increased approximately $0.7 million in the three months ended March 31, 2012.
Cost of Revenue and Gross Margin
Gross margin declined to 42.6% for the three months ended March 31, 2012, compared to 51.0% for the three months ended March 31, 2011. Gross margin in the three months ended March 31, 2012 was negatively affected by lower sales, lower utilization of our remaining wafer fabrication facility in Colorado as a result of decreased business levels and higher inventory write-downs.
We experienced an increase in inventory to $357.5 million at March 31, 2012 from $318.5 million at March 31, 2011, although our inventories declined by approximately $20.0 million from $377.4 million at the end of 2011. While we expect inventory levels to continue to decline, as builds are adjusted and as demand recovers, our inventory levels, and related write-downs, may require further adjustments during 2012 to reflect revised demand forecasts or product lifecycles. Inventory adjustments, if undertaken, may affect our results of operations, including gross margin, in a positive or negative manner, depending on the nature of those adjustments. If the demand for certain semiconductor products declines or does not materialize as we expect, we could be required to record additional write-downs, which would adversely affect our gross margin.
For the three months ended March 31, 2012, we manufactured approximately 56% of our products in our own wafer fabrication facility compared to 49% for the three months ended March 31, 2011.
Our cost of revenue includes the costs of wafer fabrication, assembly and test operations, changes in inventory write-downs, royalty expense, freight costs and stock compensation expense. Our gross margin as a percentage of net revenue fluctuates depending on product mix, manufacturing yields, utilization of manufacturing capacity, reserves for our excess and obsolete inventory, and average selling prices, among other factors.
Research and Development
Research and development (R&D) expenses increased 6%, or $3.9 million, to $66.3 million for the three months ended March 31, 2012 from $62.4 million for the three months ended March 31, 2011. R&D expenses increased for the three months ended March 31, 2012, primarily due to increased employee related expenses of $2.7 million related to product development staffing and increased stock-based compensation expense of $0.8 million. R&D expenses, including the items described above, for the three months ended March 31, 2012, were favorably affected by approximately $0.7 million due to foreign exchange rate fluctuations, compared to rates in effect and the related expenses incurred for the three months ended March 31, 2011. As a percentage of net revenue, R&D expenses totaled 19% and 14% for the three months ended March 31, 2012 and 2011, respectively.
Our internally developed process technologies are an important part of new product development. We continue to invest in developing process technologies emphasizing wireless, high voltage, analog, digital, and embedded memory manufacturing processes. Our technology development groups, in partnership with certain external foundries, are developing new and enhanced fabrication processes, including architectures utilizing advanced processes at the 65 nanometer line width node. We believe this investment allows us to bring new products to market faster, add innovative features and achieve performance improvements. We believe that continued strategic investments in process technology and product development are essential for us to remain competitive in the markets we serve.
Selling, General and Administrative
Selling, general and administrative (SG&A) expenses decreased 1%, or $0.9 million, to $69.9 million for the three months ended March 31, 2012 from $70.8 million for the three months ended March 31, 2011. SG&A expenses were favorably affected by approximately $0.4 million due to foreign exchange rate fluctuations, compared to rates in effect and the related expenses incurred for the three months ended March 31, 2011. As a percentage of net revenue, SG&A expenses totaled 20% and 15% of net revenue for the three months ended March 31, 2012 and 2011, respectively.
Stock-Based Compensation
We primarily issue restricted stock units to our employees as equity compensation. Employees may also participate in an Employee Stock Purchase Program that offers the ability to purchase stock through payroll withholdings at a discount to market price.
Stock-based compensation cost for stock options is based on the fair value of the award at the measurement date (grant date). The compensation amount for those options is calculated using a Black-Scholes option valuation model. For restricted stock unit awards, the compensation amount is determined based upon the market price of our common stock on the grant date. Stock-based compensation for restricted stock units, other than performance-based units described below, is recognized as an expense over the applicable vesting term for each employee receiving restricted stock units.
The recognition as expense of the fair value of performance-related stock-based awards is determined based upon managements estimate of the probability and timing for achieving the associated performance criteria, utilizing the fair value of the common stock on the grant date. Stock-based compensation for performance-related awards is recognized over the estimated performance period, which may vary from period to period based upon managements estimates of the timing to achieve the related performance goals. These awards vest once the performance criteria are met.
The following table summarizes the distribution of stock-based compensation expense by function for the three months ended March 31, 2012 and 2011:
In May 2011, we adopted the 2011 Long-Term Performance Based Incentive Plan (the 2011 Plan), which provides for the grant of restricted stock units to eligible employees; vesting of these restricted stock units is subject to the satisfaction of specified performance metrics tied to relative revenue growth rankings and operating margin over the designated performance periods. The performance periods for the 2011 Plan run from January 1, 2011 through December 31, 2013, consisting of three one year performance periods (calendar years 2011, 2012 and 2013) and a three year cumulative performance period. We issued 0.2 million performance-based restricted stock units in the three months ended March 31, 2012. We recorded total stock-based compensation expense related to performance-based restricted stock units of $4.3 million under the 2011 Plan in the three months ended March 31, 2012.
The 2011 Plan performance metrics include revenue growth rankings for us relative to a semiconductor peer group or a microcontroller peer group, as determined by the Compensation Committee. In addition, in order for a participant to receive credit for a performance period, we must achieve a minimum operating margin during such performance period, measured on a pro forma basis, subject to adjustment by the Compensation Committee. We evaluate, on a quarterly basis, the likelihood of meeting our performance metrics in determining stock-based compensation expense for performance share plans.
We recorded total stock based compensation expense related to performance based restricted stock units of $6.5 million under the 2008 Plan in the three months ended March 31, 2011.
Until restricted stock units are vested, they do not have the voting rights of common stock and the shares underlying the awards are not considered issued and outstanding.
Acquisition-Related Charges
We recorded total acquisition-related charges of $2.0 million for the three months ended March 31, 2012, related to our acquisitions of Advanced Digital Design and Quantum Research Group Ltd.
We recorded amortization of intangible assets of $1.4 million and $1.1 million in the three months ended March 31, 2012 and 2011, respectively, associated with customer relationships, developed technology, trade name, non-compete agreements and backlog. We estimate amortization of intangible assets will be approximately $5.5 million for 2012.
Restructuring Charges
The following table summarizes the activity related to the accrual for restructuring charges detailed by event for the three months ended March 31, 2012 and 2011:
