Industry Background

Competitive pressures require manufacturers of a wide variety of products to expand product functionality and provide differentiation while maintaining or reducing cost.  To address these requirements, manufacturers often use integrated circuit-based embedded control systems that enable them to:

• differentiate their products

• replace less efficient electromechanical control devices

• reduce the number of components in their system

• add product functionality

• reduce the system level energy consumption

• decrease time to market for their products

• significantly reduce product cost

Embedded control systems have been incorporated into thousands of products and subassemblies in a wide variety of applications and markets worldwide, including:

• automotive comfort, safety, information and entertainment applications

• remote control devices, including garage door openers

• handheld tools

• large and small home appliances

• portable computers and accessories

• robotics

• energy monitoring

• thermostats

• motor controls

• security systems

• smoke and carbon monoxide detectors

• consumer electronics

• power supplies

• applications needing touch buttons, touch screens and graphical user interfaces

• medical instruments

Embedded control systems typically incorporate a microcontroller as the principal active, and sometimes sole, component.  A microcontroller is a self-contained computer-on-a-chip consisting of a central processing unit, often with on board non-volatile program memory, random access memory for data storage and various analog and digital input/output peripheral capabilities.  In addition to the microcontroller, a complete embedded control system incorporates application-specific software, various analog, mixed-signal and connectivity products and non-volatile memory components such as EEPROMs and Flash memory.

The increasing demand for embedded control has made the market for microcontrollers one of the significant segments of the semiconductor market at approximately $15 billion in calendar year 2013.  Microcontrollers are primarily available in 8-bit through 32-bit architectures.  8-bit microcontrollers remain very cost-effective for a wide range of high-volume embedded control applications and, as a result, continue to represent a significant portion of the overall microcontroller market.  16-bit and 32-bit microcontrollers provide higher performance and functionality, and are generally found in more complex embedded control applications. The analog and mixed-signal segment of the semiconductor market is very large at approximately $40 billion in calendar year 2013, and this market is fragmented into a large number of sub segments.

Our Products

Our strategic focus is on embedded control solutions, including:

• general purpose and specialized microcontrollers

• development tools and related software

• analog and mixed signal products

• connectivity products

• memory products

• technology licensing

4

We provide highly cost-effective embedded control solutions that also offer the advantages of small size, high performance, extreme low power, wide voltage range operation, mixed signal integration, and ease of development, thus enabling timely and cost-effective integration of our solutions by our customers in their end products.

Microcontrollers

We offer a broad family of proprietary general purpose microcontroller products marketed under the PIC^® brand name.  We believe that our PIC product family is a price/performance leader in the worldwide microcontroller market.  We have shipped over 13 billion PIC microcontrollers to customers worldwide since their introduction in 1990.  We also offer specialized microcontrollers for automotive networking, computing, wireless communication and wireless audio applications. With over 1,100 microcontrollers in our product portfolio, we target the 8-bit, 16-bit, and 32-bit microcontroller markets.

We have used our manufacturing experience and design and process technology to bring additional enhancements and manufacturing efficiencies to the development and production of our PIC family of microcontroller products.  Our extensive experience base has enabled us to develop our small footprint, flexible, extreme low power, low-cost user programmability feature by incorporating non-volatile memory, such as Flash, EEPROM and EPROM memory, into the microcontroller, and to be a leader in reprogrammable microcontroller product offerings.

Development Tools

We offer a comprehensive set of low-cost and easy-to-learn application development tools.  These tools enable system designers to quickly and easily program PIC microcontrollers for specific applications and, we believe, are a key factor for facilitating design wins.

Our family of development tools for our PIC products range from entry-level systems, which include an assembler and programmer or in-circuit debugging hardware, to fully configured systems that provide in-circuit emulation capability.  Customers moving from entry-level designs to those requiring real-time emulation are able to preserve their investment in learning and tools as they migrate to future PIC devices since all of our PIC development tools share the same integrated development environment.

Many independent companies also develop and market application development tools that support our standard microcontroller product architecture.  Currently, there are approximately 200 third-party tool suppliers worldwide whose products support our proprietary microcontroller architecture.

We believe that familiarity with and adoption of both our and third-party development tools by an increasing number of product designers will be an important factor in the future selection of our embedded control products.  These development tools allow design engineers to develop thousands of application-specific products from our standard microcontrollers.  To date, we have shipped over 1.6 million development tools.

Analog, Interface and Mixed Signal Products

Our analog, interface and mixed signal products consist of several families with over 1,100 power management, linear, mixed-signal, thermal management, RF Linear drivers, safety and security, USB, ethernet, wireless and other interface products.  

We market and sell our analog, interface and mixed signal products into our microcontroller customer base, to customers who use microcontrollers from other suppliers and to customers who use other products that may not fit our traditional microcontroller and memory products customer base.  We market these, and all of our products, based on an application segment approach targeted to provide customers with application solutions.

Memory Products

Our memory products consist of serial electrically erasable programmable read-only memory (referred to as Serial EEPROMs), Serial Flash memories, Parallel Flash memories and Serial SRAM memories.  Serial EEPROMs, Serial Flash memories and Serial SRAM have a very low I/O pin requirement, permitting production of very small footprint devices.  We sell our memory products primarily into the embedded control market, complementing our microcontroller offerings.

5

Technology Licensing

Our technology licensing business includes license fees and royalties associated with technology licenses for the use of our SuperFlash^® embedded flash and Smartbits^® one time programmable NVM technologies. We also generate fees for engineering services related to these technologies.  We license our NVM technologies to foundries, integrated device manufacturers and design partners throughout the world for use in the manufacture of their advanced microcontroller products, gate array, RF and analog products that require embedded non-volatile memory.

Manufacturing

Our manufacturing operations include wafer fabrication, wafer probe, assembly and test.  The ownership of a substantial portion of our manufacturing resources is an important component of our business strategy, enabling us to maintain a high level of manufacturing control, resulting in us being one of the lowest cost producers in the embedded control industry.  By owning wafer fabrication facilities and our assembly and test operations, and by employing statistical techniques (statistical process control, designed experiments and wafer level monitoring), we have been able to achieve and maintain high production yields.  Direct control over manufacturing resources allows us to shorten our design and production cycles.  This control also allows us to capture the wafer manufacturing and a portion of the assembly and testing profit margin. We do outsource a significant portion of our manufacturing requirements to third parties and the amount of our outsourced manufacturing has increased due to our acquisitions of companies that outsource all or substantial portions of their manufacturing.

Our manufacturing facilities are located in:

• Tempe, Arizona (Fab 2)

• Gresham, Oregon (Fab 4)

• Chandler, Arizona (wafer probe)

• Bangkok, Thailand (wafer probe, assembly and test)

Wafer Fabrication

Fab 2 currently produces 8-inch wafers and supports manufacturing processes from 0.35 microns to 5.0 microns.  During fiscal 2014, in response to uncertain global economic conditions and our inventory position, we decided to operate Fab 2 below normal capacity levels, which we typically consider to be in the range of 90% to 95% of the actual capacity of the installed equipment.  Fab 2's capacity to support more advanced technologies was increased during fiscal 2014 by making process improvements, upgrading existing equipment, and adding equipment.

Fab 4 currently produces 8-inch wafers using predominantly 0.22 microns to 0.5 microns manufacturing processes and is capable of supporting technologies below 0.18 microns.  Similar to Fab 2, Fab 4 operated below normal capacity levels during fiscal 2014. A significant amount of additional clean room capacity and equipment in Fab 4 can be brought on line in the future to support incremental wafer fabrication capacity needs.  We believe the combined capacity of Fab 2 and Fab 4 will provide sufficient capacity to allow us to respond to increases in future demand over the next several years with modest incremental capital expenditures.

We continue to transition products to more advanced process technologies to reduce future manufacturing costs.  We believe that our ability to successfully transition to more advanced process technologies is important for us to remain competitive.

We have, in recent years, outsourced a larger portion of our wafer production requirements to third-party wafer foundries to augment our internal manufacturing capabilities.  As a result of our recent acquisitions, we have become more reliant on outside wafer foundries for our wafer fabrication requirements.  In fiscal 2014, approximately 38% of our sales came from products that were produced at outside wafer foundries.

Wafer Probe, Assembly and Test

We perform wafer probe, product assembly and testing at our facilities located near Bangkok, Thailand.  We also perform a limited amount of wafer probe at our Chandler, Arizona facility. During fiscal 2014, approximately 51% of our assembly requirements were being performed in our Thailand facilities and approximately 86% of our test requirements were performed in our Thailand facilities.  We use third-party assembly and test contractors in several Asian countries for the balance of our assembly and test requirements.

General Matters Impacting Our Manufacturing Operations

Due to the high fixed costs inherent in semiconductor manufacturing, consistently high manufacturing yields have significant positive effects on our gross profit and overall operating results.  Our continuous focus on manufacturing productivity has allowed us to maintain excellent manufacturing yields at our facilities.  Our manufacturing yields are primarily driven by a comprehensive implementation of statistical process control, extensive employee training and our effective use of our manufacturing facilities and equipment.  Maintenance of manufacturing productivity and yields are important factors in the achievement of our operating results.  The manufacture of integrated circuits, particularly non-volatile, erasable CMOS memory and logic devices, such as those that we produce, are complex processes.  These processes are sensitive to a wide variety of factors, including the level of contaminants in the manufacturing environment, impurities in the materials used and the performance of our manufacturing personnel and equipment.  As is typical in the semiconductor industry, we have from time to time experienced lower than anticipated manufacturing yields.  Our operating results will suffer if we are unable to maintain yields at approximately the current levels.

Historically, we have relied on our ability to respond quickly to customer orders as part of our competitive strategy, resulting in customers placing orders with relatively short delivery schedules.  In order to respond to such requirements, we have historically maintained a significant work-in-process and finished goods inventory.

At the end of fiscal 2014, we owned identifiable long-lived assets (consisting of property, plant and equipment) in the U.S. with a carrying value, net of accumulated depreciation, of $311.9 million and $220.1 million in other countries, including $179.1 million in Thailand.  At the end of fiscal 2013, we owned identifiable long-lived assets in the U.S. with a carrying value, net of accumulated depreciation, of $325.3 million and $189.2 million in other countries, including $171.1 million in Thailand. At the end of fiscal 2012, we owned identifiable long-lived assets in the U.S. with a carrying value, net of accumulated depreciation, of $314.3 million and $202.3 million in other countries, including $186.1 million in Thailand.

We have many suppliers of raw materials and subcontractors which provide our various materials and service needs. We generally seek to have multiple sources of supply for our raw materials and services, but, in some cases, we may rely on a single or limited number of suppliers. In such event, we have plans to reduce the exposure that would result from a disruption in supply.

Research and Development (R&D)

We are committed to continuing our investment in new and enhanced products, including development systems, and in our design and manufacturing process technologies.  We believe these investments are significant factors in maintaining our competitive position.  Our current R&D activities focus on the development of general purpose and specialized microcontrollers, Serial EEPROM memory, NOR FLASH memory, Embedded FLASH technologies, connectivity products, analog, interface and mixed signal products, development systems, user interface products, software and application-specific software libraries.  We are also developing design, assembly, test and process technologies to enable new products and innovative features as well as achieve further cost reductions and performance improvements in existing products.

In fiscal 2014, our R&D expenses were $305.0million, compared to $254.7million in fiscal 2013 and $182.7 million in fiscal 2012.  R&D expenses included share-based compensation expense of $24.6million in fiscal 2014, $22.2 million in fiscal 2013 and $14.7 million in fiscal 2012.

Sales and Distribution

General

We market and sell our products worldwide primarily through a network of direct sales personnel and distributors.

Our direct sales force focuses on a wide variety of strategic accounts in three geographical markets: the Americas, Europe and Asia.  We currently maintain sales and technical support centers in major metropolitan areas in all three geographic markets.  We believe that a strong technical service presence is essential to the continued development of the embedded control market.  Many of our field sales engineers (FSEs), field application engineers (FAEs), and sales management have technical degrees or backgrounds and have been previously employed in high technology environments.  We believe that the technical knowledge of our sales force is a key competitive advantage in the sale of our products.  The primary mission of our FAE team is to provide technical assistance to customers and to conduct periodic training sessions for the balance of our sales team.  FAEs also frequently conduct technical seminars and workshops in major cities around the world.

7

Our licensing division has dedicated sales, technology, design, product, test and reliability personnel that support the requirements of our licensees.

Distribution

Our distributors focus primarily on servicing the product requirements of a broad base of diverse customers.  We believe that distributors provide an effective means of reaching this broad and diverse customer base.  We believe that customers recognize us for our products and brand name and use distributors as an effective supply channel.

In each of fiscal 2014 and fiscal 2013, we derived 53% of our net sales through distributors and 47% of our net sales from customers serviced directly by us.  In fiscal 2012, we derived 59% of our net sales through distributors and 41% of our net sales from customers serviced directly by us.  Future Electronics, one of our distributors, accounted for approximately 10% of our net sales in fiscal 2012.  No other distributor or end customer accounted for more than 10% of our net sales in fiscal 2014, fiscal 2013 or fiscal 2012.

We do not have long-term agreements with our distributors and we, or our distributors, may each terminate our relationship with little or no advanced notice.  The loss of, or the disruption in the operations of, one or more of our distributors could reduce our future net sales in a given quarter and could result in an increase in inventory returns.

Sales by Geography

Sales by geography for fiscal 2014, fiscal 2013 and fiscal 2012 were as follows (dollars in thousands):

	Year Ended March 31,
	2014		%	2013		%	2012		%
Americas	$	365,609	18.9	$	313,574	19.8	$	290,392	21.0
Europe	411,531		21.3	344,398		21.8	319,881		23.1
Asia	1,154,077		59.8	923,651		58.4	772,903		55.9
Total Sales	$	1,931,217	100.0	$	1,581,623	100.0	$	1,383,176	100.0

Sales to foreign customers accounted for approximately 84% of our net sales in fiscal 2014, approximately 83% of our net sales in fiscal 2013 and approximately 82% of our net sales in fiscal 2012.  Our sales to foreign customers have been predominately in Asia and Europe, which we attribute to the manufacturing strength in those areas for automotive, communications, computing, consumer and industrial control products.  Americas' sales include sales to customers in the U.S., Canada, Central America and South America.

Sales to customers in China, including Hong Kong, accounted for approximately 29% of our net sales in fiscal 2014, approximately 27% of our net sales in fiscal 2013 and approximately 24% of our net sales in fiscal 2012.  Sales to customers in Taiwan accounted for approximately 13% of our net sales in each of fiscal 2014 and fiscal 2013 and approximately 15% of our net sales in fiscal 2012.  We did not have sales into any other foreign countries that exceeded 10% of our net sales during fiscal 2014, fiscal 2013 or fiscal 2012.

Our international sales are substantially all U.S. dollar denominated.  Although foreign sales are subject to certain government export restrictions, we have not experienced any material difficulties to date as a result of export restrictions.

The semiconductor industry is characterized by seasonality and wide fluctuations of supply and demand.  Since a significant portion of our revenue is from consumer markets and international sales, our business is subject to seasonally lower revenues in the third and fourth quarters of our fiscal year.  However, in recent periods, changes in global economic and semiconductor industry conditions have had a more significant impact on our results than seasonality, and has made it difficult to assess the impact of seasonal factors on our business.

Backlog

As of April 30, 2014, our backlog was approximately $813.1 million, compared to $611.0 million as of April 30, 2013.  Our backlog includes all purchase orders scheduled for delivery within the subsequent 12 months.

8

We primarily produce standard products that can be shipped from inventory within a relatively short time after we receive an order.  Our business and, to a large extent, that of the entire semiconductor industry, is characterized by short-term orders and shipment schedules.  Orders constituting our current backlog are subject to changes in delivery schedules, or to cancellation at the customer's option without significant penalty.  Thus, while backlog is useful for scheduling production, backlog as of any particular date may not be a reliable measure of sales for any future period.

Competition

The semiconductor industry is intensely competitive and has been characterized by price erosion and rapid technological change.  We compete with major domestic and international semiconductor companies, many of which have greater market recognition and greater financial, technical, marketing, distribution and other resources than we have with which to pursue engineering, manufacturing, marketing and distribution of their products.  We also compete with a number of companies that we believe have copied, cloned, pirated or reverse engineered our proprietary product lines in such countries as China, Korea and Taiwan.  We are continuing to take actions to vigorously and aggressively defend and protect our intellectual property on a worldwide basis.

We currently compete principally on the basis of the technical innovation and performance of our embedded control products, including the following product characteristics:

• performance

• analog, digital and mixed signal functionality and level of functional integration

• memory density

• low power consumption

• reliability

• packaging alternatives

• complete development tool chain

We believe that other important competitive factors in the embedded control market include:

• ease of use

• functionality of application development systems

• dependable delivery, quality and availability

• technical and innovative service and support

• time to market

• price

We believe that we compete favorably with other companies on all of these factors, but we may be unable to compete successfully in the future, which could harm our business.

Patents, Licenses and Trademarks

We maintain a portfolio of U.S. and foreign patents, expiring on various dates between 2014 and 2031.  We also have numerous additional U.S. and foreign patent applications pending.  We do not expect that the expiration of any particular patent will have a material impact on our business.  While we intend to continue to seek patents on our technology and manufacturing processes, we believe that our continued success depends primarily on the technological skills and innovative capabilities of our personnel and our ability to rapidly commercialize new and enhanced products, rather than on our patents.  Our existing and new patents, trademarks and copyrights that issue may not be of sufficient scope or strength to provide meaningful intellectual property protection or any commercial advantage to us.  Pursuing violations of our intellectual property rights on a worldwide basis is a complex business area involving patent law, trademark law, copyright law and the laws of certain foreign countries do not protect our intellectual property rights to the same extent as the laws of the U.S.

We have entered into certain intellectual property licenses and cross-licenses with other companies related to semiconductor products and manufacturing processes.  As is typical in the semiconductor industry, we and our customers have from time to time received, and may in the future receive, communications from third parties asserting patent or other intellectual property rights on certain of our products or technologies.  We investigate all such notices and respond as we believe is appropriate.  Based on industry practice, we believe that in most cases we can obtain necessary licenses or other rights on commercially reasonable terms, but we cannot assure that all licenses would be on acceptable terms, that litigation would not ensue or that damages for any past infringement would not be assessed.  Litigation, which could result in substantial costs to us and require significant attention from management, may be necessary to enforce our patents or other intellectual

9

property rights, or to defend us against claimed infringement of the rights of others.  The failure to obtain necessary licenses or other rights, or litigation arising out of infringement claims, could harm our business.

Environmental Regulation

We must comply with many different federal, state, local and foreign governmental regulations related to the use, storage, discharge and disposal of certain chemicals and gases used in our manufacturing processes.  Our facilities have been designed to comply with these regulations and we believe that our activities are conducted in material compliance with such regulations.  Any changes in such regulations or in their enforcement could require us to acquire costly equipment or to incur other significant expenses to comply with environmental regulations.  Any failure by us to adequately control the storage, use, discharge and disposal of regulated substances could result in significant future liabilities.

Increasing public attention has been focused on the environmental impact of electronic manufacturing operations.  While we have not experienced any materially adverse effects on our operations from recently adopted environmental regulations, our business and results of operations could suffer if for any reason we fail to control the storage or use of, or to adequately restrict the discharge or disposal of, hazardous substances under present or future environmental regulations.

Employees

As of March 31, 2014, we had 8,604 employees.  None of our employees are represented by a labor organization.  We have never had a work stoppage and believe that our employee relations are good.

 Item 1A.    RISK FACTORS

When evaluating Microchip and its business, you should give careful consideration to the factors listed below, in addition to the information provided elsewhere in this Form 10-K and in other documents that we file with the Securities and Exchange Commission.

Our operating results are impacted by global economic conditions and may fluctuate in the future due to a number of factors that could reduce our net sales and profitability.

Our operating results are affected by a wide variety of factors that could reduce our net sales and profitability, many of which are beyond our control. Some of the factors that may affect our operating results include:

• general economic, industry or political conditions in the U.S. or internationally;

• changes in demand or market acceptance of our products and products of our customers, and market fluctuations in the industries into which such products are sold;

• changes in utilization of our manufacturing capacity and fluctuations in manufacturing yields;

• our ability to secure sufficient wafer foundry, assembly and testing capacity;

• the mix of inventory we hold and our ability to satisfy orders from our inventory;

• levels of inventories held by our customers;

• risk of excess and obsolete inventories;

• changes or fluctuations in customer order patterns and seasonality;

• our ability to realize the expected benefits of our acquisitions;

• changes in tax regulations and policies in the U.S. and other countries in which we do business;

• competitive developments including pricing pressures;

• unauthorized copying of our products resulting in pricing pressure and loss of sales;

• availability of raw materials and equipment;

• the level of orders that are received and can be shipped in a quarter;

• the level of sell-through of our products through distribution;

• fluctuations in the mix of products;

• announcements of significant acquisitions;

• disruptions in our business or our customers' businesses due to terrorist activity, armed conflict, war, worldwide oil prices and supply, public health concerns, natural disasters or disruptions in the transportation system;

• constrained availability from other electronic suppliers impacting our customers' ability to ship their products, which in turn may adversely impact our sales to those customers;

• costs and outcomes of any current or future tax audits or any litigation involving intellectual property, customers or other issues;

• fluctuations in commodity prices; and

• property damage or other losses, whether or not covered by insurance.

11

We believe that period-to-period comparisons of our operating results are not necessarily meaningful and that you should not rely upon any such comparisons as indications of our future performance. In future periods, our operating results may fall below our public guidance or the expectations of public market analysts and investors, which would likely have a negative effect on the price of our common stock. Adverse global economic conditions, the subsequent economic recovery and uncertainty surrounding the strength of such recovery have caused our operating results to fluctuate significantly and make comparability between periods less meaningful.

Our operating results will suffer if we ineffectively utilize our manufacturing capacity or fail to maintain manufacturing yields.

The manufacture and assembly of integrated circuits, particularly non-volatile, erasable CMOS memory and logic devices such as those that we produce, are complex processes. These processes are sensitive to a wide variety of factors, including the level of contaminants in the manufacturing environment, impurities in the materials used, the performance of our wafer fabrication and assembly and test personnel and equipment, and other quality issues. As is typical in the semiconductor industry, we have from time to time experienced lower than anticipated manufacturing yields. Our operating results will suffer if we are unable to maintain yields at approximately the current levels. This could include delays in the recognition of revenue, loss of revenue or future orders, and customer-imposed penalties for failure to meet contractual shipment deadlines. Our operating results are also adversely affected when we operate at less than optimal capacity. For example, in the third quarter of fiscal 2012, we reduced wafer starts in both Fab 2 and Fab 4 to help control inventory balances in response to a slowdown in global economic conditions. We continued with the reduced level of wafer starts through the first quarter of fiscal 2013. These actions had a negative impact on our gross profit. We further reduced the wafer starts in our fabs in late September 2012 and again during the quarter ended December 31, 2012 which continued to negatively impact our gross profit through the March 2013 quarter. We increased wafer starts modestly throughout fiscal 2014 but were still below what we consider normal capacity levels.

We are dependent on orders that are received and shipped in the same quarter and therefore have limited visibility to future product shipments.

Our net sales in any given quarter depend upon a combination of shipments from backlog, and customer orders that are both received and shipped in that same quarter, which we refer to as turns orders. We measure turns orders at the beginning of a quarter based on the orders needed to meet the shipment targets that we set entering the quarter. Historically, we have relied on our ability to respond quickly to customer orders as part of our competitive strategy, resulting in customers placing orders with relatively short delivery schedules. Shorter lead times generally mean that turns orders as a percentage of our business are relatively high in any particular quarter and reduce our backlog visibility on future product shipments. Turns orders correlate to overall semiconductor industry conditions and product lead times. Because turns orders are difficult to predict, varying levels of turns orders make it more difficult to forecast net sales. As a significant portion of our products are manufactured at foundries, foundry lead times may affect our ability to satisfy certain turns orders. If we do not achieve a sufficient level of turns orders in a particular quarter relative to our revenue targets, our revenue and operating results will likely suffer.

Intense competition in the markets we serve may lead to pricing pressures, reduced sales of our products or reduced market share.

The semiconductor industry is intensely competitive and has been characterized by price erosion and rapid technological change. We compete with major domestic and international semiconductor companies, many of which have greater market recognition and substantially greater financial, technical, marketing, distribution and other resources than we do. We may be unable to compete successfully in the future, which could harm our business. Our ability to compete successfully depends on a number of factors both within and outside our control, including, but not limited to:

• the quality, performance, reliability, features, ease of use, pricing and diversity of our products;

• our success in designing and manufacturing new products including those implementing new technologies;

• the rate at which customers incorporate our products into their own applications and the success of such applications;

• the rate at which the markets that we serve redesign and change their own products;

• changes in demand in the markets that we serve and the overall rate of growth or contraction of such markets, including but not limited to the automotive, personal computing and consumer electronics markets;

• product introductions by our competitors;

• the number, nature and success of our competitors in a given market;

• our ability to obtain adequate foundry and assembly and test capacity and supplies of raw materials and other supplies at acceptable prices;

12

• our ability to protect our products and processes by effective utilization of intellectual property rights;

• our ability to remain price competitive against companies that have copied our proprietary product lines, especially in countries where intellectual property rights protection is difficult to achieve and maintain;

• our ability to address the needs of our customers; and

• general market and economic conditions.

Historically, average selling prices in the semiconductor industry decrease over the life of any particular product. The overall average selling prices of our microcontroller and proprietary analog, interface and mixed signal products have remained relatively constant, while average selling prices of our memory and non-proprietary analog, interface and mixed signal products have declined over time.

We have experienced, and expect to continue to experience, modest pricing declines in certain of our more mature proprietary product lines, primarily due to competitive conditions. We have been able to moderate average selling price declines in many of our proprietary product lines by continuing to introduce new products with more features and higher prices. However, there can be no assurance that we will be able to do so in the future. We have experienced in the past, and expect to continue to experience in the future, varying degrees of competitive pricing pressures in our memory and non-proprietary analog products. We may be unable to maintain average selling prices for our products as a result of increased pricing pressure in the future, which could adversely impact our operating results.

We are dependent on wafer foundries and other contractors to perform key manufacturing functions for us, and our licensees of our SuperFlash technology also rely on foundries and other contractors.

We rely on outside wafer foundries for a significant portion of our wafer fabrication needs. We also use several contractors located in Asia for a portion of the assembly and testing of our products. Our reliance on third party contractors and foundries increased as a result of our acquisition of SMSC in August 2012 and will increase further as a result of our acquisition of Supertex in April 2014. Although we own the majority of our manufacturing resources, the disruption or termination of any of our contractors could harm our business and operating results.

Our use of third parties somewhat reduces our control over the subcontracted portions of our business. Our future operating results could suffer if any contractor were to experience financial, operational or production difficulties or situations when demand exceeds capacity, or if they were unable to maintain manufacturing yields, assembly and test yields and costs at approximately their current levels, or if they were to experience political upheaval or infrastructure disruption. If these third parties are unable or unwilling to timely deliver products or services conforming to our quality standards, we may not be able to qualify additional manufacturing sources for our products in a timely manner or at all, or on terms favorable to us. Additionally, these subcontractors could abandon fabrication processes that are important to us, or fail to adopt advanced manufacturing technologies that we desire to control costs. In any such event, we could experience an interruption in production, an increase in manufacturing and production costs or a decline in product reliability, and our business and operating results could be adversely affected. Further, use of subcontractors increases opportunities for potential misappropriation of our intellectual property.

Certain of our SuperFlash technology licensees also rely on outside wafer foundries for wafer fabrication services. If our licensees were to experience any disruption in supply from wafer foundries, this would reduce the revenue we receive in our technology licensing business and would harm our operating results.

Our business is dependent on selling through distributors.

Sales through distributors accounted for approximately 53% of our net sales in each of fiscal 2014 and fiscal 2013. We do not have long-term agreements with our distributors and we and our distributors may each terminate our relationship with little or no advance notice.

Any future adverse conditions in the U.S. or global economies or in the U.S. or global credit markets could materially impact the operations of our distributors. Any deterioration in the financial condition of our distributors or any disruption in the operations of our distributors could adversely impact the flow of our products to our end customers and adversely impact our results of operation. In addition, during an industry or economic downturn, it is possible there will be an oversupply of products and a decrease in sell-through of our products by our distributors which could reduce our net sales in a given period and result in an increase in inventory returns. Violations of the Foreign Corrupt Practices Act, or similar laws, by our distributors or other channel partners could have a material adverse impact on our business.

13

Our success depends on our ability to introduce new products on a timely basis.

Our future operating results depend on our ability to develop and timely introduce new products that compete effectively on the basis of price and performance and which address customer requirements. The success of our new product introductions depends on various factors, including, but not limited to:

• proper new product selection;

• timely completion and introduction of new product designs;

• procurement of licenses for intellectual property rights from third parties under commercially reasonable terms;

• timely filing and protection of intellectual property rights for new product designs;

• availability of development and support tools and collateral literature that make complex new products easy for engineers to understand and use; and

• market acceptance of our customers' end products.

Because our products are complex, we have experienced delays from time to time in completing new product development. In addition, our new products may not receive or maintain substantial market acceptance.  We may be unable to timely design, develop and introduce competitive products, which could adversely impact our future operating results.

Our success also depends upon our ability to develop and implement new design and process technologies. Semiconductor design and process technologies are subject to rapid technological change and require significant R&D expenditures. We and other companies in the industry have, from time to time, experienced difficulties in effecting transitions to advanced process technologies and, consequently, have suffered reduced manufacturing yields or delays in product deliveries. Our future operating results could be adversely affected if any transition to future process technologies is substantially delayed or inefficiently implemented.

Our technology licensing business exposes us to various risks.

Our technology licensing business is based on our SuperFlash technology. The success of our licensing business will depend on the continued market acceptance of this technology and on our ability to further develop and enhance such technology and to introduce new technologies in the future. To be successful, any such technology must be able to be repeatably implemented by licensees, provide satisfactory yield rates, address licensee and customer requirements, and perform competitively. The success of our technology licensing business depends on various other factors, including, but not limited to:

• proper identification of licensee requirements;

• timely development and introduction of new or enhanced technology;

• our ability to protect our intellectual property rights for our licensed technology;

• our ability to limit our liability and indemnification obligations to licensees;

• availability of sufficient development and support services to assist licensees in their design and manufacture of products integrating our technology;

• availability of foundry licensees with sufficient capacity to support OEM production; and

• market acceptance of our customers' end products.

Because our SuperFlash technology is complex, there may be delays from time to time in developing and enhancing such technology. There can be no assurance that our existing or any enhanced or new technology will achieve or maintain substantial market acceptance. Our licensees may experience disruptions in production or lower than expected production levels which would adversely affect the revenue that we receive from them. Our technology license agreements generally include an indemnification clause that indemnifies the licensee against liability and damages (including legal defense costs) arising from intellectual property matters. We could be exposed to substantial liability for claims or damages related to intellectual property matters or indemnification claims. Any claim, with or without merit, could result in significant legal fees and require significant attention from our management. Any of the foregoing issues may adversely impact the success of our licensing business and adversely affect our future operating results.

Our operating results may be impacted by both seasonality and the wide fluctuations of supply and demand in the semiconductor industry.

The semiconductor industry is characterized by seasonality and wide fluctuations of supply and demand. Since a significant portion of our revenue is from consumer markets and international sales, our business is subject to seasonally lower revenues in the third and fourth quarters of our fiscal year. However, broad fluctuations in our overall business in recent

14

periods and changes in semiconductor industry and global economic conditions have had a more significant impact on our results than seasonality, and have made it difficult to assess the impact of seasonal factors on our business. The industry has also experienced significant economic downturns, characterized by diminished product demand and production over-capacity. We have sought to reduce our exposure to this industry cyclically by selling proprietary products, that cannot be easily or quickly replaced, to a geographically diverse customer base across a broad range of market segments. However, we have experienced substantial period-to-period fluctuations in operating results and expect, in the future, to experience period-to-period fluctuations in operating results due to general industry or economic conditions.

We may not fully realize the anticipated benefits of our completed or future acquisitions or divestitures.

We have acquired, and expect in the future to acquire, additional businesses that we believe will complement or augment our existing businesses. In this regard, in April 2014, we completed our acquisition of Supertex; and in August 2012, we completed our acquisition of SMSC. The integration process for our acquisitions may be complex, costly and time consuming and include unanticipated issues, expenses and liabilities. We may not be able to successfully or profitably integrate, operate, maintain and manage any newly acquired operations or employees. We may not be able to maintain uniform standards, procedures and policies and we may be unable to realize the expected synergies and cost savings from the integration. There may be increased risk due to integrating financial reporting and internal control systems. We may have difficulty in developing, manufacturing and marketing the products of a newly acquired company, or in growing the business at the rate we anticipate. Following an acquisition, we may not achieve the revenue or net income levels that justify the acquisition. We may suffer loss of key employees, customers and strategic partners of acquired companies and it may be difficult to implement our corporate culture at acquired companies. We may be subject to claims from terminated employees, shareholders of acquired companies and other third parties related to the transaction. Acquisitions may also result in one-time charges (such as acquisition-related expenses, write-offs, restructuring charges, or future impairment of goodwill), contingent liabilities, adverse tax consequences, additional stock-based compensation expense and other charges that adversely affect our operating results. Additionally, we may fund acquisitions of new businesses or strategic alliances by utilizing cash, borrowings under our credit agreement, raising debt, issuing shares of common stock, or other mechanisms.

Further, if we decide to sell assets or a business, we may encounter difficulty in finding or completing divestiture opportunities or alternative exit strategies on acceptable terms or in a timely manner. These circumstances could delay the accomplishment of our strategic objectives or cause us to incur additional expenses with respect to a business that we want to dispose of, or we may dispose of a business at a price or on terms that are less favorable than we had anticipated. Even following a divestiture, we may be contractually obligated with respect to certain continuing obligations to customers, vendors or other third parties and such obligations may have a material adverse impact on our results of operation and financial condition.

In addition to acquisitions, we have in the past, and expect in the future, to enter into joint development agreements or other business or strategic relationships with other companies. These transactions are subject to a number of risks similar to those we face with our acquisitions including our ability to realize the expected benefits of any such transaction, to successfully market and sell any products resulting from such transactions or to successfully integrate any technology developed through such transactions.

We may lose sales if our suppliers of raw materials and equipment fail to meet our needs.

Our semiconductor manufacturing operations require raw and processed materials and equipment that must meet exacting standards.  We generally have more than one source for these supplies, but there are only a limited number of suppliers capable of delivering various materials and equipment that meet our standards.  The materials and equipment necessary for our business could become more difficult to obtain as worldwide use of semiconductors in product applications increases. Additionally, consolidation in our supply chain due to mergers and acquisitions may reduce the number of suppliers or change the relationships that we have with our suppliers. This could impair sourcing flexibility or increase costs. We have experienced supply shortages from time to time in the past, and on occasion our suppliers have told us they need more time than expected to fill our orders or that they will no longer support certain equipment with updates or spare and replacement parts. An interruption of any materials or equipment sources, or the lack of supplier support for a particular piece of equipment, could harm our business.

We are exposed to various risks related to legal proceedings or claims.

We are currently, and in the future may be, involved in legal proceedings or claims regarding patent infringement, other intellectual property rights, contracts and other matters. As is typical in the semiconductor industry, we receive notifications from customers or licensees from time to time who believe that we owe them indemnification or other obligations related to

15

infringement claims made against us, our customers or our licensees by third parties. These legal proceedings and claims, even if meritless, could result in substantial cost to us and divert our resources. If we are not able to resolve a claim, settle a matter, obtain necessary licenses on commercially reasonable terms, reengineer our products or processes to avoid infringement, and/or successfully prosecute or defend our position, we could incur uninsured liability in any of them, be required to take an appropriate charge to operations, be enjoined from selling a material portion of our products or using certain processes, suffer a reduction or elimination in the value of our inventories, and our business, financial condition or results of operations could be harmed.

It is also possible that from time to time we may be subject to claims related to the manufacture, performance or use of our products. These claims may be due to injuries or environmental exposures related to manufacturing, a product's nonconformance to our specifications, or specifications agreed upon with the customer, changes in our manufacturing processes, or unexpected customer system issues due to the integration of our products or insufficient design or testing by our customers. We could incur significant expenses related to such matters, including, but not limited to:

• costs related to writing off the value of our inventory of nonconforming products;

• recalling nonconforming products;

• providing support services, product replacements, or modifications to products and the defense of such claims;

• diversion of resources from other projects;

• lost revenue or a delay in the recognition of revenue due to cancellation of orders and unpaid receivables;

• customer imposed fines or penalties for failure to meet contractual requirements; and

• a requirement to pay damages.

Because the systems into which our products are integrated have a higher cost of goods than the products we sell, our expenses and damages may be significantly higher than the sales and profits we received from the products involved. While we specifically exclude consequential damages in our standard terms and conditions, certain of our contracts may not exclude such liabilities. Further, our ability to avoid such liabilities may be limited by applicable law. We do have liability insurance which covers certain damages arising out of product defects, but we do not expect that insurance will cover all claims or be of a sufficient amount to fully protect against such claims. Costs or payments we may make in connection with these customer claims may adversely affect the results of our operations.

Further, we sell to customers in industries such as automotive, aerospace, and medical, where failure of the systems in which our products are integrated could cause damage to property or persons. We may be subject to claims if our products, or the integration of our products, cause system failures. We will face increased exposure to claims if there are substantial increases in either the volume of our sales into these applications or the frequency of system failures integrating our products.

Failure to adequately protect our intellectual property could result in lost revenue or market opportunities.

Our ability to obtain patents, licenses and other intellectual property rights covering our products and manufacturing processes is important for our success. To that end, we have acquired certain patents and patent licenses and intend to continue to seek patents on our technology and manufacturing processes. The process of seeking patent protection can be long and expensive, and patents may not be issued from currently pending or future applications. In addition, our existing and new patents, trademarks and copyrights that issue may not have sufficient scope or strength to provide meaningful protection or commercial advantage to us. We may be subject to, or may ourselves initiate, interference proceedings in the U.S. Patent and Trademark Office, patent offices of a foreign country or U.S. or foreign courts, which can require significant financial and management resources. In addition, the laws of certain foreign countries do not protect our intellectual property rights to the same extent as the laws of the U.S. Infringement of our intellectual property rights by a third party could result in uncompensated lost market and revenue opportunities for us. Although we continue to vigorously and aggressively defend and protect our intellectual property on a worldwide basis, there can be no assurance that we will be successful in our endeavors.

Our operating results may be adversely impacted if economic conditions impact the financial viability of our licensees, customers, distributors, or suppliers.

We regularly review the financial performance of our licensees, customers, distributors and suppliers. However, any downturn in global economic conditions may adversely impact the financial viability of our licensees, customers, distributors or suppliers. The financial failure of a large licensee, customer or distributor, an important supplier, or a group thereof, could have an adverse impact on our operating results and could result in our not being able to collect our accounts receivable balances, higher reserves for doubtful accounts, write-offs for accounts receivable, and higher operating costs as a percentage of revenues.

16

We do not typically have long-term contracts with our customers, but where we do, certain terms of such contracts expose us to risks and liabilities.

We do not typically enter into long-term contracts with our customers and we cannot be certain about future order levels from our customers. When we do enter into customer contracts, the contract is generally cancelable at the convenience of the customer. Even though we had approximately 84,000 customers and our ten largest direct customers made up approximately 10% of our total revenue for fiscal 2014, cancellation of customer contracts could have an adverse impact on our revenue and profits.

We have entered into contracts with certain customers that differ from our standard terms of sale. Further, as a result of our acquisitions of SMSC and Supertex, we inherited certain customer contracts that differ from our standard terms of sale. For several of the significant markets that we sell into, such as the automotive and personal computer markets, our current or potential customers may possess significant leverage over us in negotiating the terms and conditions of supply as a result of their market size and position. For example, under certain contracts we may commit to supply specific quantities of products on scheduled delivery dates, or agree to extend our obligations for certain liabilities such as warranties or indemnification for quality issues or claims of intellectual property infringement. If we are unable to supply the customer as required under the contract, the customer may incur additional production costs, lost revenues due to subsequent delays in their own manufacturing schedule, or quality-related issues. We may be liable for the customer's costs, expenses and damages associated with their claims and we may be obligated to defend the customer against claims of intellectual property infringement and pay the associated legal fees. While we try to limit the number of contracts that we sign which contain such special provisions, manage the risks underlying such liabilities, and set caps on our liability exposure, sometimes we may not be able to do so. In order to win important designs, avoid losing business to competitors, maintain existing business, or be permitted to bid on new business, we have been, and may in the future be, forced to agree to uncapped liability for such items as intellectual property infringement or confidentiality. Such provisions expose us to risk of liability far exceeding the purchase price of the products we sell under such contracts, the lifetime revenues we receive from such products, or various forms of potential consequential damages. These significant additional risks could result in a material adverse impact on our results of operation and financial condition.

We must attract and retain qualified personnel to be successful, and competition for qualified personnel can be intense.

Our success depends upon the efforts and abilities of our senior management, engineering, manufacturing and other personnel. The competition for qualified engineering and management personnel can be intense. We may be unsuccessful in retaining our existing key personnel or in attracting and retaining additional key personnel that we require. The loss of the services of one or more of our key personnel or the inability to add key personnel could harm our business. The loss of, or any inability to attract personnel, even if not key personnel, if experienced in sufficient numbers could harm our business. We have no employment agreements with any member of our senior management team. 

Business interruptions to our operations or the operations of our key vendors, subcontractors, licensees or customers, whether due to natural disasters or other events, could harm our business.

Operations at any of our facilities, at the facilities of any of our wafer fabrication or assembly and test subcontractors, or at any of our significant vendors or customers may be disrupted for reasons beyond our control. These reasons may include work stoppages, power loss, incidents of terrorism or security risk, political instability, public health issues, telecommunications, transportation or other infrastructure failure, radioactive contamination, fire, earthquake, floods, volcanic eruptions or other natural disasters. We have taken steps to mitigate the impact of some of these events should they occur; however, we cannot be certain that our actions will be effective to avoid a significant impact on our business in the event of a disaster or other business interruption.

In particular, Thailand has experienced periods of severe flooding in recent years; however, our facilities in Thailand have continued to operate normally. There can be no assurance that any future flooding in Thailand would not have a material adverse impact on our operations. If operations at any of our facilities, or our subcontractors' facilities are interrupted, we may not be able to shift production to other facilities on a timely basis, and we may need to spend significant amounts to repair or replace our facilities and equipment.  If we experienced business interruptions, we would likely experience delays in shipments of products to our customers and alternate sources for production may be unavailable on acceptable terms. This could result in reduced revenues and profits and the cancellation of orders or loss of customers. Although we maintain business interruption insurance, such insurance will likely not be enough to compensate us for any losses that may occur and any losses or damages incurred by us as a result of business interruptions could significantly harm our business.

17

Additionally, as described above, operations at our customers and licensees may be disrupted for a number of reasons. In the event of customer disruptions, sales of our products may decline and our revenue, profitability and financial condition could suffer. Likewise, if our licensees are unable to manufacture and ship products incorporating our technology, or if there is a decrease in product demand due to a business disruption, our royalty revenue may decline as our licenses are based on per unit royalties.

We are highly dependent on foreign sales and operations, which exposes us to foreign political and economic risks.

Sales to foreign customers account for a substantial portion of our net sales. During fiscal 2014, approximately 84% of our net sales were made to foreign customers, including 29% in China. During fiscal 2013, approximately 83% of our net sales were made to foreign customers, including 27% in China. A strong position in the Chinese market is a key component of our global growth strategy. The market for integrated circuit products in China is highly competitive, and both international and domestic competitors are aggressively seeking to increase their market share. Increased competition in the China market may make it difficult for us to achieve our desired sales volumes in China. We purchase a substantial portion of our raw materials and equipment from foreign suppliers. In addition, we own product assembly and testing facilities near Bangkok, Thailand, which is currently experiencing political instability, and has experienced periods of political instability in the past. From time to time, Thailand has also experienced periods of severe flooding. There can be no assurance that any future flooding in Thailand would not have a material adverse impact on our operations. We use various foreign contractors for a significant portion of our assembly and testing and wafer fabrication requirements. Substantially all of our finished goods inventory is maintained in Thailand.

Our reliance on foreign operations, foreign suppliers, maintenance of substantially all of our finished goods inventory at foreign locations and significant foreign sales exposes us to foreign political and economic risks, including, but not limited to:

• political, social and economic instability;

• economic uncertainty in the worldwide markets served by us;

• public health conditions;

• trade restrictions and changes in tariffs;

• import and export license requirements and restrictions;

• changes in rules and laws related to taxes, environmental, health and safety, technical standards and consumer protection in various jurisdictions;

• difficulties in staffing and managing international operations;

• employment regulations;

• disruptions in international transport or delivery;

• difficulties in collecting receivables and longer payment cycles;

• currency fluctuations and foreign exchange regulations; and

• potentially adverse tax consequences.

If any of these risks materialize, or are worse than we anticipate, our sales could decrease and our operating results could suffer.

Fluctuations in foreign currency exchange rates could adversely impact our operating results.

We use forward currency exchange contracts in an attempt to reduce the adverse earnings impact from the effect of exchange rate fluctuations on our non-U.S. dollar net balance sheet exposures. Nevertheless, in periods when the U.S. dollar significantly fluctuates in relation to the non-U.S. currencies in which we transact business, the value of our non-U.S. dollar transactions can have an adverse effect on our results of operations and financial condition. In particular, in periods when a foreign currency significantly declines in value in relation to the U.S. dollar, such as past declines in the Euro relative to the U.S. dollar, customers transacting in that foreign currency may find it more difficult to fulfill their previously committed contractual obligations or to undertake new obligations to make payments or purchase products. In periods when the U.S. dollar is significantly declining in relation to the British pound, Euro and Thai baht, the operational costs in our European and Thailand subsidiaries are adversely affected.

18

Interruptions in our information technology systems could adversely affect our business.

We rely on the efficient and uninterrupted operation of complex information technology systems and networks to operate our business.  Any significant disruption to our systems or networks, including, but not limited to, new system implementations, computer viruses, security breaches, facility issues, natural disasters, terrorism, war, telecommunication failures or energy blackouts could have a material adverse impact on our operations, sales and operating results.  Such disruption could result in a loss of our intellectual property or the release of sensitive competitive information or supplier, customer or employee personal data. Any loss of such information could harm our competitive position, result in a loss of customer confidence, and cause us to incur significant costs to remedy the damages caused by the disruptions or security breaches. Additionally, failure to properly manage the collection, handling, transfer or disposal of personal data of employees and customers may result in regulatory penalties, enforcement actions, remediation obligations, litigation, fines and other sanctions.

From time to time, we have experienced verifiable attacks on our data, attempts to breach our security and attempts to introduce malicious software into our IT systems; however, such attacks have not previously resulted in any material damage to us. Were future attacks successful, we may be unaware of the incident, its magnitude, or its effects until significant harm is done. In recent years, we have implemented improvements to our protective measures which are not limited to the following: firewalls, antivirus measures, patches, log monitors, routine backups with offsite retention of storage media, system audits, data partitioning and routine password modifications. There can be no assurance that such system improvements will be sufficient to prevent or limit the damage from any future cyber attack or disruptions. Any such attack or disruption could result in additional costs related to rebuilding of internal systems, defending litigation, responding to regulatory actions, or paying damages. Such attacks or disruption could have a material adverse impact on our business, operations and financial results.

Third-party service providers, such as wafer foundries, assembly and test contractors, distributors, credit card processors and other vendors have access to certain portions of our and our customers' sensitive data. In the event that these service providers do not properly safeguard the data that they hold, security breaches and loss of data could result. Any such loss of data by our third-party service providers could negatively impact our business, operations and financial results, as well as our relationship with our customers.

The occurrence of events for which we are self-insured, or which exceed our insurance limits, may adversely affect our profitability and liquidity.

We have insurance contracts with independent insurance companies related to many different types of risk; however, we self-insure for some potentially significant risks and obligations. In these circumstances, we believe that it is more cost effective for us to self-insure certain risks than to pay the high premium costs. The risks and exposures that we self-insure include, but are not limited to certain property, product defects, employment risks, political risks, and intellectual property matters. Should there be a loss or adverse judgment or other decision in an area for which we are self-insured, then our financial condition, results of operations and liquidity may be adversely affected.

We are subject to stringent environmental and other regulations, which may force us to incur significant expenses.

We must comply with many federal, state, local and foreign governmental regulations related to the use, storage, discharge and disposal of toxic, volatile or otherwise hazardous substances used in our products and manufacturing processes.  Our failure to comply with applicable regulations could result in fines, suspension of production, cessation of operations or future liabilities. Such environmental regulations have required us in the past, and could require us in the future to buy costly equipment or to incur significant expenses to comply with such regulations. Our failure to control the use of, or adequately restrict the discharge of, hazardous substances could impact the health of our employees and others and could impact our ability to operate. Such failure could also restrict our ability to ship certain products to certain countries, require us to modify our operations logistics, or require us to incur other significant costs and expenses. There is a continuing expansion in environmental laws with a focus on reducing or eliminating hazardous substances and substances of high concern in electronic products and shipping materials. These and other future environmental regulations could require us to reengineer certain of our existing products and may make it more expensive for us to manufacture, sell and ship our products. In addition, the number and complexity of laws focused on the energy efficiency of electronic products and accessories, the recycling of electronic products, and the reduction in quantity and the recycling of packing materials have expanded significantly. It may be difficult for us to timely comply with these laws and we may not have sufficient quantities of compliant products to meet customers' needs, thereby adversely impacting our sales and profitability. We may also have to write off inventory in the event that we hold unsaleable inventory as a result of changes to regulations or customer requirements. We expect these risks and trends to continue. In addition, we anticipate increased customer requirements to meet voluntary criteria related to the reduction or elimination of substances of high concern in our products and energy efficiency measures. These requirements may increase our own costs, as well as those passed on to us by our supply chain.

19

Customer demands for us to implement business practices that are more stringent than legal requirements may reduce our revenue opportunities or cause us to incur higher costs.

Some of our customers and potential customers are requiring that we implement operating practices that are more stringent than what is required by applicable laws with respect to workplace and labor requirements, the type of materials we use in our products, environmental matters or other items. To comply with such requirements, we may have to pass these same operating practices on to our suppliers. Our suppliers may refuse to implement these operating practices, or may charge us more for complying with them. The cost to implement such practices may cause us to incur higher costs and reduce our profitability, and if we choose not to implement such practices, such customers may disqualify us as a supplier, resulting in decreased revenue opportunities. Developing, administering, monitoring and auditing these customer-requested practices at our own sites and those in our supply chain will increase our costs and may require that we hire more personnel.

Customer demands and new regulations related to conflict-free minerals may force us to incur additional expenses.

As required by the Dodd-Frank Wall Street Reform and Consumer Protection Act, in August 2012, the SEC released new disclosure and reporting requirements regarding the use of “conflict” minerals mined from the Democratic Republic of Congo and adjoining countries in products, necessary to the functionality or production of products, whether or not these products are manufactured by third parties.  We must file a report on Form SD with the SEC regarding such matters by June 2, 2014 and on an annual basis thereafter. Other countries are considering similar regulations.  As we implement these new requirements, if it is determined that we are using other than conflict-free minerals, customers may demand us to change the sourcing of minerals used in the manufacture of semiconductor devices (including our products), even if the costs for compliant minerals significantly increases and availability is limited.  If we make changes to materials and/or suppliers, there will likely be costs associated with qualifying new suppliers and production capacity and quality could be negatively impacted.  There will likely be additional costs associated with complying with these new disclosure requirements, such as costs related to determining the source of any conflict minerals used in our products.  Also, since our supply chain is complex, we may face reputational challenges if we are unable to sufficiently verify the origins for all metals used in our products through the procedures we may implement.  We may also encounter challenges to satisfy those customers who require that all of the components of our products are certified as conflict free.  If we are not able to meet customer requirements, customers may choose to disqualify us as a supplier and we may have to write off inventory in the event that it cannot be sold.

Regulatory authorities in jurisdictions into which we ship our products could levy fines or restrict our ability to export products.

A significant portion of our sales are made outside of the U.S. through the exporting and re-exporting of products. In addition to local jurisdictions' export regulations, our U.S.-manufactured products or products based on U.S. technology are subject to U.S. laws and regulations governing international trade and exports, including, but not limited to the Foreign Corrupt Practices Act, Export Administration Regulations (EAR), and trade sanctions against embargoed countries and destinations administered by the U.S. Department of the Treasury, Office of Foreign Assets Control (OFAC). Licenses or proper license exceptions are required for the shipment of our products to certain countries. A determination by the U.S. or foreign government that we have failed to comply with these or other export regulations or anti-bribery regulations can result in penalties which may include denial of export privileges, fines, civil or criminal penalties, and seizure of products. Such penalties could have a material adverse effect on our business, sales and earnings. Further, a change in these laws and regulations could restrict our ability to export to previously permitted countries, customers, distributors or other third parties. Any one or more of these sanctions or a change in laws or regulations could have a material adverse effect on our business, financial condition and results of operations.

The outcome of currently ongoing and future examinations of our income tax returns by the IRS could have an adverse effect on our results of operations.

We are subject to examination of our income tax returns by the IRS and other tax authorities for fiscal 2011 and later. Microchip and SMSC are currently under IRS audit for fiscal 2011 and 2012.  We are subject to certain income tax examinations in foreign jurisdictions for fiscal 2006 and later. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. There can be no assurance that the outcomes from these continuing examinations will not have an adverse effect on our future operating results.

20

The future trading price of our common stock could be subject to wide fluctuations in response to a variety of factors.

The market price of our common stock has fluctuated significantly in the past and is likely to fluctuate in the future. The future trading price of our common stock could be subject to wide fluctuations in response to a variety of factors, many of which are beyond our control, including, but not limited to:

• quarterly variations in our operating results or the operating results of other technology companies;

• general conditions in the semiconductor industry;

• global economic and financial conditions;

• changes in analysts' estimates of our financial performance or buy/sell recommendations;

• changes in our financial guidance or our failure to meet such guidance;

• any acquisitions we pursue or complete; and

• actual or anticipated announcements of technical innovations or new products by us or our competitors.

In addition, the stock market has from time to time experienced significant price and volume fluctuations that have affected the market prices for many companies and that often have been unrelated to the operating performance of such companies. These broad market fluctuations and other factors have harmed and may harm the market price of our common stock. Some or all of the foregoing factors could also cause the market price of our convertible debentures to decline or fluctuate substantially.

We may in the future incur impairments to goodwill or long-lived assets.

We review our long-lived assets, including goodwill and other intangible assets, for impairment annually in the fourth fiscal quarter or whenever events or changes in circumstances indicate that the carrying amount of those assets may not be recoverable. Factors that may be considered in assessing whether goodwill or intangible assets may not be recoverable include a decline in our stock price or market capitalization, reduced estimates of future cash flows and slower growth rates in our industry. Our valuation methodology for assessing impairment requires management to make judgments and assumptions based on historical experience and to rely heavily on projections of future operating performance. Because we operate in highly competitive environments, projections of our future operating results and cash flows may vary significantly from our actual results. No goodwill or material long-lived asset impairment charges were recorded in fiscal 2013 or fiscal 2014.

Our financial condition and results of operations could be adversely affected if we do not effectively manage our current or future debt.

In June 2013, we entered into a $2.0 billion credit agreement. At March 31, 2014, we had $650.0 million in outstanding borrowings under such credit agreement. In December 2007, we sold $1.15 billion of principal value 2.125% junior subordinated convertible debentures. As a result of such transactions, we have a substantially greater amount of debt than we had maintained in the past. Our maintenance of substantial levels of debt could adversely affect our ability to take advantage of corporate opportunities and could adversely affect our financial condition and results of operations. We may need or desire to refinance all or a portion of our loans under our credit agreement, our debentures or any other future indebtedness and there can be no assurance that we will be able to refinance any of our indebtedness on commercially reasonable terms, if at all.

Conversion of our debentures will dilute the ownership interest of existing stockholders, including holders who had previously converted their debentures.

The conversion of some or all of our outstanding debentures will dilute the ownership interest of existing stockholders to the extent we deliver common stock upon conversion of the debentures. Upon conversion, we may satisfy our conversion obligation by delivering cash, shares of common stock or any combination, at our option. If upon conversion we elect to deliver cash for the lesser of the conversion value and principal amount of the debentures, we would pay the holder the cash value of the applicable number of shares of our common stock. Upon conversion, we intend to satisfy the lesser of the principal amount or the conversion value of the debentures in cash. If the conversion value of a debenture exceeds the principal amount of the debenture, we may also elect to deliver cash in lieu of common stock for the conversion value in excess of the one thousand dollars principal amount (i.e., the conversion spread). There would be no adjustment to the numerator in the net income per common share computation for the cash settled portion of the debentures as that portion of the debt instrument will always be settled in cash. The conversion spread will be included in the denominator for the computation of diluted net income per common share. Any sales in the public market of any common stock issuable upon conversion of our debentures could adversely affect prevailing market prices of our common stock. In addition, the existence of the debentures may encourage short selling by market participants because the conversion of the debentures could be used to satisfy short positions, or anticipated conversion of the debentures into shares of our common stock could depress the price of our common stock.

21

Our reported financial results may be adversely affected by new accounting pronouncements or changes in existing accounting standards and practices.

We prepare our financial statements in conformity with accounting principles generally accepted in the U.S. These accounting principles are subject to interpretation or changes by the FASB and the SEC. New accounting pronouncements and varying interpretations of accounting standards and practices have occurred in the past and are expected to occur in the future. New accounting pronouncements or a change in the interpretation of existing accounting standards or practices may have a significant effect on our reported financial results and may even affect our reporting of transactions completed before the change is announced or effective.

Potential U.S. tax legislation regarding our foreign earnings could materially and adversely impact our business and financial results.

Currently, a majority of our revenue is generated from customers located outside the U.S., and a substantial portion of our assets, including employees, are located outside the U.S. Present U.S. income taxes and foreign withholding taxes have not been provided on undistributed earnings for certain of our non-U.S. subsidiaries, because such earnings are intended to be indefinitely reinvested in the operations of those subsidiaries. In recent years, there have been a number of initiatives proposed by the Obama administration and members of Congress regarding the tax treatment of such undistributed earnings. If adopted, certain of these initiatives would substantially reduce our ability to defer U.S. taxes including repealing the deferral of U.S. taxation of foreign earnings, eliminating utilization of or substantially reducing our ability to claim foreign tax credits, and eliminating various tax deductions until foreign earnings are repatriated to the U.S. Changes in tax law such as these proposals could have a material negative impact on our financial position and results of operations.

Climate change regulations and sustained adverse climate change pose regulatory and physical risks that could harm our results of operations or affect the way we conduct business.

Climate change regulations could require us to limit emissions, change our manufacturing processes, obtain substitute materials which may cost more or be less available, increase our investment in control technology for greenhouse gas emissions, fund offset projects or undertake other costly activities. These regulations could significantly increase our costs and restrict our manufacturing operations by virtue of requirements for new equipment. New permits may be required for our current operations, or expansions thereof. Failure to timely receive permits could result in fines, suspension of production, or cessation of operations at one or more facilities. In addition, restrictions on carbon dioxide or other greenhouse gas emissions could result in significant costs such as higher energy costs, and utility companies passing down carbon taxes, emission cap and trade programs and renewable portfolio standards. The cost of complying, or of failing to comply, with these and other climate change and emissions regulations could have an adverse effect on our operating results.

Further, any sustained adverse change in climate could have a direct adverse economic impact on us, such as water and power shortages, higher costs of water or energy to control the temperature of our facilities. Certain of our operations are located in arid or tropical regions, such as Thailand and Arizona. Some environmental experts predict that these regions may become vulnerable to storms, severe floods and droughts due to climate change. While we maintain business recovery plans that are intended to allow us to recover from natural disasters or other events that can interrupt business, we cannot be certain that our plans will protect us from all such disasters or events.

Item 3.    LEGAL PROCEEDINGS

In the ordinary course of our business, we are involved in a limited number of legal actions, both as plaintiff and defendant, and could incur uninsured liability in any one or more of them. We also periodically receive notification from various third parties alleging infringement of patents, intellectual property rights or other matters. With respect to these pending legal actions to which we are a party, although the outcome of these actions are generally not determinable, we believe that the ultimate resolution of these matters will not harm our business and will not have a material adverse effect on our financial position, cash flows or results of operations.  Litigation relating to the semiconductor industry is not uncommon, and we are, and from time to time have been, subject to such litigation.  No assurances can be given with respect to the extent or outcome of any such litigation in the future.

Introduction

The following discussion should be read in conjunction with the consolidated financial statements and the related notes that appear elsewhere in this document, as well as with other sections of this Annual Report on Form 10-K, including "Item 1 – Business;" "Item 6 – Selected Financial Data;" and "Item 8 – Financial Statements and Supplementary Data."

We begin our Management's Discussion and Analysis of Financial Condition and Results of Operations (MD&A) with a summary of our overall business strategy to give the reader an overview of the goals of our business and the overall direction of our business and products.  This is followed by a discussion of the Critical Accounting Policies and Estimates that we believe are important to understanding the assumptions and judgments incorporated in our reported financial results.  In the next section, beginning at page 34, we discuss our Results of Operations for fiscal 2014 compared to fiscal 2013, and for fiscal 2013 compared to fiscal 2012.  We then provide an analysis of changes in our balance sheet and cash flows, and discuss our financial

28

commitments in the sections titled "Liquidity and Capital Resources," "Contractual Obligations" and "Off-Balance Sheet Arrangements."

Strategy

Our goal is to be a worldwide leader in providing specialized semiconductor products for a wide variety of embedded control applications.  Our strategic focus is on the embedded control market, which includes microcontrollers, high-performance analog, interface and mixed signal devices, power management and thermal management devices, connectivity devices, interface devices, Serial EEPROMs, SuperFlash memory products, our patented KeeLoq^® security devices and Flash IP solutions.  We provide highly cost-effective embedded control products that also offer the advantages of small size, high performance, low voltage/power operation and ease of development, enabling timely and cost-effective embedded control product integration by our customers.  We license our SuperFlash technology to wafer foundries, integrated device manufacturers and design partners throughout the world for use in the manufacture of their advanced microcontroller products.

We sell our products to a broad base of domestic and international customers across a variety of industries. The principal markets that we serve include consumer, automotive, industrial, office automation and telecommunications.  Our business is subject to fluctuations based on economic conditions within these markets. 

Our manufacturing operations include wafer fabrication, wafer probe and assembly and test.  The ownership of a substantial portion of our manufacturing resources is an important component of our business strategy, enabling us to maintain a high level of manufacturing control resulting in us being one of the lowest cost producers in the embedded control industry.  By owning wafer fabrication facilities and our assembly and test operations, and by employing statistical process control techniques, we have been able to achieve and maintain high production yields.  Direct control over manufacturing resources allows us to shorten our design and production cycles.  This control also allows us to capture a portion of the wafer manufacturing and the assembly and test profit margin. We do outsource a significant portion of our manufacturing requirements to third parties.

We employ proprietary design and manufacturing processes in developing our embedded control products.  We believe our processes afford us both cost-effective designs in existing and derivative products and greater functionality in new product designs.  While many of our competitors develop and optimize separate processes for their logic and memory product lines, we use a common process technology for both microcontroller and non-volatile memory products.  This allows us to more fully leverage our process research and development costs and to deliver new products to market more rapidly.  Our engineers utilize advanced computer-aided design (CAD) tools and software to perform circuit design, simulation and layout, and our in-house photomask and wafer fabrication facilities enable us to rapidly verify design techniques by processing test wafers quickly and efficiently.

We are committed to continuing our investment in new and enhanced products, including development systems, and in our design and manufacturing process technologies.  We believe these investments are significant factors in maintaining our competitive position.  Our current research and development activities focus on the design of new microcontrollers, digital signal controllers, memory, analog and mixed-signal products, Flash-IP systems, new development systems, software and application-specific software libraries.  We are also developing new design and process technologies to achieve further cost reductions and performance improvements in our products.

We market and sell our products worldwide primarily through a network of direct sales personnel and distributors.  Our distributors focus primarily on servicing the product and technical support requirements of a broad base of diverse customers.  We believe that our direct sales personnel combined with our distributors provide an effective means of reaching this broad and diverse customer base.  Our direct sales force focuses primarily on major strategic accounts in three geographical markets: the Americas, Europe and Asia.  We currently maintain sales and support centers in major metropolitan areas in North America, Europe and Asia.  We believe that a strong technical service presence is essential to the continued development of the embedded control market.  Many of our field sales engineers (FSEs), field application engineers (FAEs), and sales management personnel have technical degrees and have been previously employed in an engineering environment.  We believe that the technical knowledge of our sales force is a key competitive advantage in the sale of our products.  The primary mission of our FAE team is to provide technical assistance to strategic accounts and to conduct periodic training sessions for FSEs and distributor sales teams.  FAEs also frequently conduct technical seminars for our customers in major cities around the world, and work closely with our distributors to provide technical assistance and end-user support.

Critical Accounting Policies and Estimates

General

Our discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S.  We review the accounting policies we use in reporting our financial results on a regular basis.  The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent liabilities.  On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, business combinations, share-based compensation, inventories, income taxes, junior subordinated convertible debentures and contingencies.  We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources.  Our results may differ from these estimates due to actual outcomes being different from those on which we based our assumptions.  We review these estimates and judgments on an ongoing basis.  We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements.  We also have other policies that we consider key accounting policies, such as our policy regarding revenue recognition to original equipment manufacturers (OEMs); however, we do not believe these policies require us to make estimates or judgments that are as difficult or subjective as our policies described below.

Revenue Recognition – Distributors

Our distributors worldwide generally have broad price protection and product return rights, so we defer revenue recognition until the distributor sells the product to their customer.  Revenue is recognized when the distributor sells the product to an end-user, at which time the sales price becomes fixed or determinable.  Revenue is not recognized upon shipment to our distributors since, due to discounts from list price as well as price protection rights, the sales price is not substantially fixed or determinable at that time.  At the time of shipment to these distributors, we record a trade receivable for the selling price as there is a legally enforceable right to payment, relieve inventory for the carrying value of goods shipped since legal title has passed to the distributor, and record the gross margin in deferred income on shipments to distributors on our consolidated balance sheets.

Deferred income on shipments to distributors effectively represents the gross margin on the sale to the distributor; however, the amount of gross margin that we recognize in future periods could be less than the deferred margin as a result of credits granted to distributors on specifically identified products and customers to allow the distributors to earn a competitive gross margin on the sale of our products to their end customers and price protection concessions related to market pricing conditions.

We sell the majority of the items in our product catalog to our distributors worldwide at a uniform list price.  However, distributors resell our products to end customers at a very broad range of individually negotiated price points.  The majority of our distributors' resales require a reduction from the original list price paid.  Often, under these circumstances, we remit back to the distributor a portion of their original purchase price after the resale transaction is completed in the form of a credit against the distributors' outstanding accounts receivable balance.  The credits are on a per unit basis and are not given to the distributor until they provide information to us regarding the sale to their end customer.  The price reductions vary significantly based on the customer, product, quantity ordered, geographic location and other factors and discounts to a price less than our cost have historically been rare.  The effect of granting these credits establishes the net selling price to our distributors for the product and results in the net revenue recognized by us when the product is sold by the distributors to their end customers.  Thus, a portion of the "deferred income on shipments to distributors" balance represents the amount of distributors' original purchase price that will be credited back to the distributor in the future.  The wide range and variability of negotiated price concessions granted to distributors does not allow us to accurately estimate the portion of the balance in the deferred income on shipments to distributors account that will be credited back to the distributors.  Therefore, we do not reduce deferred income on shipments to distributors or accounts receivable by anticipated future concessions; rather, price concessions are typically recorded against deferred income on shipments to distributors and accounts receivable when incurred, which is generally at the time the distributor sells the product.  At March 31, 2014, we had approximately $222.8 million of deferred revenue and $75.0 million in deferred cost of sales recognized as $147.8 million of deferred income on shipments to distributors.  At March 31, 2013, we

30

had approximately $201.8 million of deferred revenue and $62.8 million in deferred cost of sales recognized as $139.0 million of deferred income on shipments to distributors.  The deferred income on shipments to distributors that will ultimately be recognized in our income statement will be lower than the amount reflected on the balance sheet due to additional price credits to be granted to the distributors when the product is sold to their customers.  These additional price credits historically have resulted in the deferred income approximating the overall gross margins that we recognize in the distribution channel of our business.

Distributor advances, reflected as a reduction of deferred income on shipments to distributors on our consolidated balance sheets, totaled $92.8 million at March 31, 2014 and $70.1 million at March 31, 2013.  On sales to distributors, our payment terms generally require the distributor to settle amounts owed to us for an amount in excess of their ultimate cost.  The sales price to our distributors may be higher than the amount that the distributors will ultimately owe us because distributors often negotiate price reductions after purchasing products from us and such reductions are often significant.  It is our practice to apply these negotiated price discounts to future purchases, requiring the distributor to settle receivable balances, on a current basis, generally within 30 days, for amounts originally invoiced.  This practice has an adverse impact on the working capital of our distributors.  As such, we have entered into agreements with certain distributors whereby we advance cash to the distributors to reduce the distributor's working capital requirements.  These advances are reconciled at least on a quarterly basis and are estimated based on the amount of ending inventory as reported by the distributor multiplied by a negotiated percentage.  Such advances have no impact on our revenue recognition or our consolidated statements of income.  We process discounts taken by distributors against our deferred income on shipments to distributors' balance and true-up the advanced amounts generally after the end of each completed fiscal quarter.  The terms of these advances are set forth in binding legal agreements and are unsecured, bear no interest on unsettled balances and are due upon demand.  The agreements governing these advances can be canceled by us at any time.

We reduce product pricing through price protection based on market conditions, competitive considerations and other factors.  Price protection is granted to distributors on the inventory they have on hand at the date the price protection is offered.  When we reduce the price of our products, it allows the distributor to claim a credit against its outstanding accounts receivable balances based on the new price of the inventory it has on hand as of the date of the price reduction.  There is no immediate revenue impact from the price protection, as it is reflected as a reduction of the deferred income on shipments to distributors' balance.

Products returned by distributors and subsequently scrapped have historically been immaterial to our consolidated results of operations.  We routinely evaluate the risk of impairment of the deferred cost of sales component of the deferred income on shipments to distributors account.  Because of the historically immaterial amounts of inventory that have been scrapped, and historically rare instances where discounts given to a distributor result in a price less than our cost, we believe the deferred costs are recorded at their approximate carrying value.

Business Combinations

All of our business combinations are accounted for at fair value under the acquisition method of accounting.  Under the acquisition method of accounting, (i) acquisition-related costs, except for those costs incurred to issue debt or equity securities, will be expensed in the period incurred; (ii) non-controlling interests will be valued at fair value at the acquisition date; (iii) in-process research and development will be recorded at fair value as an intangible asset at the acquisition date and amortized once the technology reaches technological feasibility; (iv) restructuring costs associated with a business combination will be expensed subsequent to the acquisition date; and (v) changes in deferred tax asset valuation allowances and income tax uncertainties after the acquisition date will be recognized through income tax expense or directly in contributed capital.  The measurement of the fair value of assets acquired and liabilities assumed requires significant judgment.  The valuation of intangible assets and acquired investments, in particular, requires that we use valuation techniques such as the income approach.  The income approach includes the use of a discounted cash flow model, which includes discounted cash flow scenarios and requires the following significant estimates:  revenue, expenses, capital spending and other costs, and discount rates based on the respective risks of the cash flows.  The valuation of non-marketable equity investments acquired also takes into account variables such as conditions reflected in the capital markets, recent financing activity by the investees, the investees' capital structure and the terms of the investees' issued interests.

31

Share-based Compensation

We measure at fair value and recognize compensation expense for all share-based payment awards, including grants of employee stock options, restricted stock units (RSUs) and employee stock purchase rights, to be recognized in our financial statements based on their respective grant date fair values.  Total share-based compensation in fiscal 2014 was $53.8 million, of which $46.4 million was reflected in operating expenses.  Total share-based compensation included in cost of sales in fiscal 2014 was $7.3 million.  Total share-based compensation included in our inventory balance was $5.7 million at March 31, 2014.

Determining the appropriate fair-value model and calculating the fair value of share-based awards at the date of grant requires judgment.  The fair value of our RSUs is based on the fair market value of our common stock on the date of grant discounted for expected future dividends.  We use the Black-Scholes option pricing model to estimate the fair value of employee stock options and rights to purchase shares under our employee stock purchase plans.  Option pricing models, including the Black-Scholes model, require the use of input assumptions, including expected volatility, expected life, expected dividend rate, and expected risk-free rate of return.  We use a blend of historical and implied volatility based on options freely traded in the open market as we believe this is most reflective of market conditions and a better indicator of expected volatility than using purely historical volatility.  The expected life of the awards is based on historical and other economic data trended into the future.  The risk-free interest rate assumption is based on observed interest rates appropriate for the terms of our awards.  The dividend yield assumption is based on our history and expectation of future dividend payouts.  We estimate the number of share-based awards that will be forfeited due to employee turnover.  Quarterly changes in the estimated forfeiture rate can have a significant effect on reported share-based compensation, as the impact on prior period amortization for all unvested awards is recognized in the period the forfeiture estimate is changed.  If the actual forfeiture rate is higher or lower than the estimated forfeiture rate, then an adjustment is made to increase or decrease the estimated forfeiture rate, which will result in a decrease or increase to the expense recognized in our financial statements.  If forfeiture adjustments are made, they would affect our gross margin, research and development expenses, and selling, general, and administrative expenses.  The effect of forfeiture adjustments in fiscal 2014 was immaterial.

We evaluate the assumptions used to value our awards on a quarterly basis.  If factors change and we employ different assumptions, share-based compensation expense may differ significantly from what we have recorded in the past.  If there are any modifications or cancellations of the underlying unvested securities, we may be required to accelerate, increase or cancel any remaining unearned share-based compensation expense.  Future share-based compensation expense and unearned share-based compensation will increase to the extent that we grant additional equity awards to employees or we assume unvested equity awards in connection with acquisitions. 

Inventories

Inventories are valued at the lower of cost or market using the first-in, first-out method.  We write down our inventory for estimated obsolescence or unmarketable inventory in an amount equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions.  If actual market conditions are less favorable than those we projected, additional inventory write-downs may be required.  Inventory impairment charges establish a new cost basis for inventory and charges are not subsequently reversed to income even if circumstances later suggest that increased carrying amounts are recoverable.  In estimating our inventory obsolescence, we primarily evaluate estimates of demand over a 12-month period and record impairment charges for inventory on hand in excess of the estimated 12-month demand. Estimates for projected 12-month demand are generally based on the average shipments of the prior three-month period, which are then annualized to adjust for any potential seasonality in our business. The estimated 12-month demand is compared to our most recently developed sales forecast to further reconcile the 12-month demand estimate. Management reviews and adjusts the estimates as appropriate based on specific situations. For example, demand can be adjusted up for new products for which historic sales are not representative of future demand. Alternatively, demand can be adjusted down to the extent any existing products are being replaced or discontinued.

In periods where our production levels are substantially below our normal operating capacity, the reduced production levels of our manufacturing facilities are charged directly to cost of sales. As a result of decreased production in our wafer fabrication facilities, approximately $19.0 million, $31.7 million and $6.7 million was charged directly to cost of sales in fiscal 2014, fiscal 2013 and fiscal 2012, respectively.

32

Income Taxes

As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate.  This process involves estimating our actual current tax exposure together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes.  These differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheets.  We must then assess the likelihood that our deferred tax assets will be recovered from future taxable income within the relevant jurisdiction and to the extent we believe that recovery is not likely, we must establish a valuation allowance.  We have provided valuation allowances for certain of our deferred tax assets, including state net operating loss carryforwards, foreign tax credits and state tax credits, where it is more likely than not that some portion, or all of such assets, will not be realized. At March 31, 2014, the valuation allowances totaled $93.8 million. Should we determine that we would not be able to realize all or part of our net deferred tax asset in the future, an adjustment to the deferred tax asset would be charged to income in the period such determination was made.  At March 31, 2014, our deferred tax asset, net of valuation allowances, was $238.2million.

Various taxing authorities in the U.S. and other countries in which we do business scrutinize the tax structures employed by businesses.  Companies of our size and complexity are regularly audited by the taxing authorities in the jurisdictions in which they conduct significant operations.  Microchip and SMSC are currently under IRS audit for fiscal years 2011 and 2012. We recognize liabilities for anticipated tax audit issues in the U.S. and other tax jurisdictions based on our estimate of whether, and the extent to which, additional tax payments are probable.  We believe that we maintain adequate tax reserves to offset any potential tax liabilities that may arise upon these and other pending audits in the U.S. and other countries in which we do business.  If such amounts ultimately prove to be unnecessary, the resulting reversal of such reserves would result in tax benefits being recorded in the period the reserves are no longer deemed necessary.  If such amounts ultimately prove to be less than an ultimate assessment, a future charge to expense would be recorded in the period in which the assessment is determined. 

Junior Subordinated Convertible Debentures

We separately account for the liability and equity components of our junior subordinated convertible debentures in a manner that reflects our nonconvertible debt (unsecured debt) borrowing rate when interest cost is recognized.  This results in a bifurcation of a component of the debt, classification of that component in equity and the accretion of the resulting discount on the debt to be recognized as part of interest expense in our consolidated statements of income.  Lastly, we include the dilutive effect of the shares of our common stock issuable upon conversion of the outstanding junior subordinated convertible debentures in our diluted income per share calculation regardless of whether the market price trigger or other contingent conversion feature has been met.  We apply the treasury stock method as we have the intent and have adopted an accounting policy to settle the principal amount of the junior subordinated convertible debentures in cash.  This method results in incremental dilutive shares when the average fair value of our common stock for a reporting period exceeds the conversion price per share, which was $25.87 at March 31, 2014, and adjusts as dividends are recorded in the future.

Contingencies

In the ordinary course of our business, we are involved in a limited number of legal actions, both as plaintiff and defendant, and could incur uninsured liability in any one or more of them.  We also periodically receive notifications from various third parties alleging infringement of patents, intellectual property rights or other matters.  With respect to pending legal actions to which we are a party, although the outcomes of these actions are not generally determinable, we believe that the ultimate resolution of these matters will not have a material adverse effect on our financial position, cash flows or results of operations.  Litigation relating to the semiconductor industry is not uncommon, and we are, and from time to time have been, subject to such litigation.  No assurances can be given with respect to the extent or outcome of any such litigation in the future.

Net Sales

We operate in two industry segments and engage primarily in the design, development, manufacture and sale of semiconductor products as well as the licensing of Flash intellectual property.  We sell our products to distributors and original equipment manufacturers, referred to as OEMs, in a broad range of markets, perform ongoing credit evaluations of our customers and generally require no collateral.  In certain circumstances, a customer's financial condition may require collateral, and, in such cases, the collateral would be typically provided by letters of credit.

Our net sales of $1,931.2million in fiscal 2014 increased by $349.6 million, or 22.1%, over fiscal 2013, and our net sales of $1,581.6 million in fiscal 2013 increased by $198.4 million, or 14.4%, from fiscal 2012.  The increase in net sales in fiscal 2014 over fiscal 2013 was due primarily to general economic and semiconductor industry conditions and market share gains. The increase in net sales in fiscal 2014 over fiscal 2013 was also impacted by our acquisition of SMSC on August 2, 2012. The increase in net sales in fiscal 2013 over fiscal 2012 was due primarily to our acquisition of SMSC offset in part by adverse general economic and semiconductor industry conditions.  Average selling prices for our semiconductor products were up approximately 4% in fiscal 2014 over fiscal 2013 and were up approximately 5% in fiscal 2013 over fiscal 2012. The number of units of our semiconductor products sold was up approximately 17% in fiscal 2014 over fiscal 2013 and up approximately 10% in fiscal 2013 over fiscal 2012. The average selling prices and the unit volumes of our sales are impacted by the mix of our products sold and overall semiconductor market conditions.  Key factors impacting the amount of net sales during the last three fiscal years include:

• global economic conditions in the markets we serve;

• semiconductor industry conditions;

• our acquisition of SMSC in the second quarter of fiscal 2013;

• inventory holding patterns of our customers;

• increasing semiconductor content in our customers' products;

• customers' increasing needs for the flexibility offered by our programmable solutions;

• our new product offerings that have increased our served available market; and

• continued market share gains in the segments of the markets we address.

Net sales by product line for fiscal 2014, 2013 and 2012 were as follows (dollars in thousands):

	Year Ended March 31,
	2014		%	2013		%	2012		%
Microcontrollers	$	1,260,988	65.3	$	1,035,514	65.5	$	928,509	67.1

Microcontrollers

Our microcontroller product line represents the largest component of our total net sales.  Microcontrollers and associated application development systems accounted for approximately 65.3% of our total net sales in fiscal 2014, approximately 65.5% of our total net sales in fiscal 2013 and 67.1% of our total net sales in fiscal 2012.

Net sales of our microcontroller products increased approximately 21.8% in fiscal 2014 compared to fiscal 2013, and increased approximately 11.5% in fiscal 2013 compared to fiscal 2012.  The increase in net sales in fiscal 2014 compared to fiscal 2013 resulted primarily from market share gains and general economic and semiconductor industry conditions in the end markets we serve including the consumer, automotive, industrial control, communications and computing markets. The increase in net sales in fiscal 2013 compared to fiscal 2012 resulted primarily from our acquisition of SMSC and market share gains which offset weak general economic and semiconductor industry conditions.

Historically, average selling prices in the semiconductor industry decrease over the life of any particular product.  The overall average selling prices of our microcontroller products have remained relatively constant over time due to the proprietary nature of these products.  We have experienced, and expect to continue to experience, moderate pricing pressure in certain microcontroller product lines, primarily due to competitive conditions.  We have in the past been able to, and expect in the future to be able to, moderate average selling price declines in our microcontroller product lines by introducing new products with more features and higher prices.  We may be unable to maintain average selling prices for our microcontroller products as a result of increased pricing pressure in the future, which could adversely affect our operating results.

Analog, Interface and Mixed Signal Products

Sales of our analog, interface and mixed signal products accounted for approximately 22.2% of our total net sales in fiscal 2014, approximately 19.4% of our total net sales in fiscal 2013 and approximately 12.4% of our total net sales in fiscal 2012.

Net sales of our analog, interface and mixed signal products increased approximately 39.1% in fiscal 2014 compared to fiscal 2013 and increased approximately 79.8% in fiscal 2013 compared to fiscal 2012.  The increase in net sales in fiscal 2014 compared to fiscal 2013 was driven primarily by general economic and semiconductor industry conditions and market share gains achieved within the analog, interface and mixed signal market. The increase in net sales in fiscal 2013 compared to fiscal 2012 was driven primarily by our acquisition of SMSC and market share gains achieved within the analog, interface and mixed signal market.

Analog, interface and mixed signal products can be proprietary or non-proprietary in nature.  Currently, we consider more than 80% of our analog, interface and mixed signal product mix to be proprietary in nature, where prices are relatively stable, similar to the pricing stability experienced in our microcontroller products.  The non-proprietary portion of our analog, interface and mixed signal business will experience price fluctuations, driven primarily by the current supply and demand for those products.  We may be unable to maintain the average selling prices of our analog, interface and mixed signal products as a result of increased pricing pressure in the future, which could adversely affect our operating results.  We anticipate the proprietary portion of our analog, interface and mixed signal products will increase over time.

Memory Products

Sales of our memory products accounted for approximately 7.0% of our total net sales in fiscal 2014, approximately 9.0% of our total net sales in fiscal 2013 and approximately 13.0% of our total net sales in fiscal 2012.

Net sales of our memory products decreased approximately 5.6% in fiscal 2014 compared to fiscal 2013, and decreased approximately 20.5% in fiscal 2013 compared to fiscal 2012.  The decreases in memory product net sales in fiscal 2014 compared to fiscal 2013 and in fiscal 2013 compared to fiscal 2012 were driven primarily by adverse customer demand conditions within the Serial EEPROM and Flash memory markets.

Memory product pricing has historically been cyclical in nature, with steep price declines followed by periods of relative price stability, driven by changes in industry capacity at different stages of the business cycle.  We have experienced, and expect to continue to experience, varying degrees of competitive pricing pressures in our memory products.  We may be unable to maintain the average selling prices of our memory products as a result of increased pricing pressure in the future, which could adversely affect our operating results.

35

Technology Licensing

Technology licensing revenue includes a combination of royalties associated with licenses for the use of our SuperFlash technology and fees for engineering services. Technology licensing accounted for approximately 4.9% of our total net sales in fiscal 2014, approximately 5.3% of our total net sales in fiscal 2013 and approximately 6.3% of our total net sales in fiscal 2012.

Net sales related to our technology licensing increased approximately 12.9% in fiscal 2014 compared to fiscal 2013 and decreased approximately 3.7% in fiscal 2013 compared to fiscal 2012. The increase in technology licensing net sales in fiscal 2014 compared to fiscal 2013 was driven primarily by the adoption of our technology by more manufacturers of semiconductors as well as semiconductor industry and global economic conditions. The decrease in technology licensing net sales in fiscal 2013 compared to fiscal 2012 was due primarily to adverse semiconductor industry and global economic conditions.

Other

 Revenue from assembly and test subcontracting services accounted for approximately 0.6% of our total net sales in fiscal 2014, approximately 0.8% of our total net sales in fiscal 2013 and approximately 1.2% of our total net sales in fiscal 2012.

Distribution

Distributors accounted for approximately 53% of our net sales in each of fiscal 2014 and fiscal 2013 and approximately 59% of our net sales in fiscal 2012. The decrease in distributor net sales as a percentage of our total net sales in fiscal 2014 and fiscal 2013 compared to fiscal 2012 was driven primarily by our acquisition of SMSC which makes a larger percentage of its net sales to OEM customers rather than through distributors.

Our two largest distributors together accounted for approximately 14% of our net sales in fiscal 2014, approximately 13% of our net sales in fiscal 2013 and approximately 14% of our net sales in fiscal 2012. One of our distributors, Future Electronics, accounted for approximately 10% of our net sales in fiscal 2012.  No other distributor accounted for more than 10% of our net sales in fiscal 2014, fiscal 2013 or fiscal 2012.

Generally, we do not have long-term agreements with our distributors and we, or our distributors, may terminate our relationship with each other with little or no advanced notice.  The loss of, or the disruption in the operations of, one or more of our distributors could reduce our future net sales in a given quarter and could result in an increase in inventory returns.

At March 31, 2014, our distributors maintained 33 days of inventory of our products compared to 30 days at March 31, 2013 and 31 days at March 31, 2012.  Over the past three fiscal years, the days of inventory maintained by our distributors have fluctuated between approximately 27 days and 47 days.  We do not believe that inventory holding patterns at our distributors will materially impact our net sales, due to the fact that we recognize revenue based on sell-through for all of our distributors.

Net Sales by Geography

Net sales by geography for fiscal 2014, 2013 and 2012 were as follows (dollars in thousands):

	Year Ended March 31,
	2014		%	2013		%	2012		%
Americas	$	365,609	18.9	$	313,574	19.8	$	290,392	21.0
Europe	411,531		21.3	344,398		21.8	319,881		23.1
Asia	1,154,077		59.8	923,651		58.4	772,903		55.9
Total net sales	$	1,931,217	100.0	$	1,581,623	100.0	$	1,383,176	100.0

Our sales to foreign customers have been predominately in Asia and Europe, which we attribute to the manufacturing strength in those areas for automotive, communications, computing, consumer and industrial control products.  Americas sales include sales to customers in the U.S., Canada, Central America and South America.

Sales to foreign customers accounted for approximately 84% of our net sales in fiscal 2014, approximately 83% of our net sales in fiscal 2013 and approximately 82% of our net sales in fiscal 2012.  Substantially all of our foreign sales are U.S. dollar denominated.  Sales to customers in Asia have generally increased over time due to many of our customers transitioning their

36

manufacturing operations to Asia and growth in demand from the emerging Asian market as well as our acquisitions such as SMSC which had a significant concentration of sales in Asia.  Our sales force in the Americas and Europe supports a significant portion of the design activity for products which are ultimately shipped to Asia.

Sales to customers in China, including Hong Kong, accounted for approximately 29% of our net sales in fiscal 2014, approximately 27% of our net sales in fiscal 2013 and approximately 24% of our net sales in fiscal 2012.  Sales to customers in Taiwan accounted for approximately 13% of our net sales in each of fiscal 2014 and fiscal 2013 and approximately 15% of our net sales in fiscal 2012.  We did not have sales into any other countries that exceeded 10% of our net sales during the last three fiscal years.

Gross Profit

Our gross profit was $1,128.7 million in fiscal 2014, $838.5 million in fiscal 2013 and $799.3 million in fiscal 2012.  Gross profit as a percent of sales was 58.4% in fiscal 2014, 53.0% in fiscal 2013 and 57.8% in fiscal 2012.

The most significant factors affecting our gross profit percentage in the periods covered by this report were:

• production levels being below the range of our normal capacity, resulting in excess capacity charges of $19.0 million in fiscal 2014, $31.7 million in fiscal 2013 and $6.7 million in the second half of fiscal 2012 compared to production levels being at or above the range of our normal capacity levels in the first half of fiscal 2012;

• charges of approximately $53.6 million in fiscal 2013 related to the recognition of acquired inventory at fair value as a result of our acquisitions which increased the value of acquired inventory and reduced our gross margins;

• for each of fiscal 2013 and fiscal 2012, inventory write-downs being higher than the gross margin impact of sales of inventory that was previously written down; and

• fluctuations in the product mix of microcontrollers, analog products, memory products and technology licensing.

Other factors that impacted our gross profit percentage in the periods covered by this report include:

• continual cost reductions in wafer fabrication and assembly and test manufacturing, such as new manufacturing technologies and more efficient manufacturing techniques; and

• lower depreciation as a percentage of cost of sales.

We adjust our wafer fabrication and assembly and test capacity utilization as required to respond to actual and anticipated business and industry-related conditions.  When production levels are below normal capacity, we charge cost of sales for the unabsorbed capacity. Our wafer fabrication facilities operated below normal capacity levels, which we typically consider to be 90% to 95% of the actual capacity of the installed equipment, during fiscal 2014, fiscal 2013 and the second half of fiscal 2012 in response to uncertain global economic conditions and our inventory position. As a result of decreased production in our wafer fabs, approximately $19.0 million, $31.7 million and $6.7 was charged to cost of sales in fiscal 2014, fiscal 2013 and fiscal 2012, respectively. In the future, if production levels are below normal capacity, we will charge cost of sales for the unabsorbed capacity.  During fiscal 2014 and the first half of fiscal 2012, we operated at the normal levels of capacity at our Thailand assembly and test facility, and we selectively increased our assembly and test capacity at such facility during such time. During fiscal 2013 and the second half of fiscal 2012, we operated below the normal capacity levels of our Thailand assembly and test facility due to adverse business conditions and these actions had a negative impact on our gross margins during such periods.

The process technologies utilized in our wafer fabs impact our gross margins.  Fab 2 currently utilizes various manufacturing process technologies, but predominantly utilizes our 0.5 micron to 1.0 micron processes.  Fab 4 predominantly utilizes our 0.22 micron to 0.5 micron processes.  We continue to transition products to more advanced process technologies to reduce future manufacturing costs.  All of our production has been on 8-inch wafers during the periods covered by this report.

Our overall inventory levels were $262.7 million at March 31, 2014, compared to $242.3 million at March 31, 2013 and $217.3 million at March 31, 2012.  We maintained 118 days of inventory on our balance sheet at March 31, 2014 compared to 116 days of inventory at March 31, 2013 and 138 days at March 31, 2012.  We expect our inventory levels in the June 2014 quarter to decrease between 7 and 11 days from the March 2014 levels. We believe our existing level of inventory will allow us to maintain competitive lead times, provide strong delivery performance to our customers and allow us to keep our fiscal 2015 capital expenditures at relatively low levels.

37

We anticipate that our gross margins will fluctuate over time, driven primarily by capacity utilization levels, the overall product mix of microcontroller, analog, interface and mixed signal products, memory products and technology licensing revenue and the percentage of net sales of each of these products in a particular quarter, as well as manufacturing yields, fixed cost absorption, and competitive and economic conditions in the markets we serve.

During fiscal 2014, approximately 51% of our assembly requirements were performed in our Thailand facilities, compared to approximately 60% during fiscal 2013 and approximately 66% during fiscal 2012.  The percentage of our assembly work that is performed internally fluctuates over time based on supply and demand conditions in the semiconductor industry, our internal capacity capabilities and our acquisition activities.  Third-party contractors located in Asia perform the balance of our assembly operations.  During fiscal 2014, approximately 86% of our test requirements were performed in our Thailand facilities compared to approximately 87% during fiscal 2013 and approximately 92% during fiscal 2012. We believe that the assembly and test operations performed at our Thailand facilities provide us with significant cost savings compared to contractor assembly and test costs, as well as increased control over these portions of the manufacturing process.

We rely on outside wafer foundries for a significant portion of our wafer fabrication requirements. During fiscal 2014, approximately 38% of our sales came from products that were produced at outside wafer foundries compared to approximately 33% during fiscal 2013 and approximately 20% during fiscal 2012. The primary reason for the increased percentage in fiscal 2014 over the previous two fiscal years was our acquisition of SMSC in the September 2012 quarter, as SMSC relied solely on outside wafer foundries for their wafer fabrication requirements.

Our use of third parties involves some reduction in our level of control over the portions of our business that we subcontract.  While we review the quality, delivery and cost performance of our third-party contractors, our future operating results could suffer if any third-party contractor is unable to maintain manufacturing yields, assembly and test yields and costs at approximately their current levels.

Research and Development (R&D)

R&D expenses for fiscal 2014 were $305.0 million, or 15.8% of sales, compared to $254.7 million, or 16.1% of sales, for fiscal 2013 and $182.7 million, or 13.2% of sales, for fiscal 2012.  We are committed to investing in new and enhanced products, including development systems software, and in our design and manufacturing process technologies.  We believe these investments are significant factors in maintaining our competitive position.  R&D costs are expensed as incurred.  Assets purchased to support our ongoing research and development activities are capitalized when related to products which have achieved technological feasibility or that have alternative future uses and are amortized over their expected useful lives.  R&D expenses include labor, depreciation, masks, prototype wafers, and expenses for the development of process technologies, new packages, and software to support new products and design environments.

R&D expenses increased $50.3 million, or 19.8%, for fiscal 2014 over fiscal 2013.  The primary reasons for the dollar increase in R&D costs in fiscal 2014 compared to fiscal 2013 were additional costs from our acquisition of SMSC as well as higher headcount costs and bonus costs.  R&D expenses increased $72.1 million, or 39.5%, for fiscal 2013 over fiscal 2012.  The primary reasons for the dollar increase in R&D costs in fiscal 2013 compared to fiscal 2012 were additional costs from our acquisition of SMSC and higher headcount costs.  

R&D expenses fluctuate over time, primarily due to revenue and operating expense investment levels.

Selling, General and Administrative

Selling, general and administrative expenses for fiscal 2014 were $267.3million, or 13.8% of sales, compared to $261.5 million, or 16.5% of sales, for fiscal 2013, and $208.3 million, or 15.1% of sales, for fiscal 2012.  Selling, general and administrative expenses include salary expenses related to field sales, marketing and administrative personnel, advertising and promotional expenditures and legal expenses.  Selling, general and administrative expenses also include costs related to our direct sales force and field applications engineers who work in sales offices worldwide to stimulate demand by assisting customers in the selection and use of our products.

Selling, general and administrative expenses increased $5.8 million, or 2.2%, for fiscal 2014 over fiscal 2013. The primary reasons for the dollar increase in selling, general and administrative expenses in fiscal 2014 over fiscal 2013 were higher headcount costs related to our acquisition of SMSC and higher bonus costs partially offset by lower acquisition related legal expenses, professional services and share-based compensation. Selling, general and administrative expenses increased $53.2million, or 25.5%, for fiscal 2013 over fiscal 2012.  The primary reason for the dollar increase in selling, general and administrative expenses in fiscal 2013 over fiscal 2012 were additional costs from our acquisition of SMSC.   

38

Selling, general and administrative expenses fluctuate over time, primarily due to revenue and operating expense investment levels.

Special Charges

Acquisition Related Expenses

During fiscal 2014, we incurred special charges of $3.0 million related to severance, office closing and other costs associated with our acquisition activity. During fiscal 2013, we incurred special charges of $32.2 million comprised of a $4.4 million net increase in the fair value of contingent consideration related to one of our acquisitions, $16.3 million of primarily severance-related costs in addition to office closing, and other costs associated with the acquisition of SMSC and legal settlement costs of approximately $11.5 million for certain legal matters related to SST (which we acquired in April 2010) in excess of previously accrued amounts. During fiscal 2012, special charges included a benefit of $0.7 million comprised of a $1.0 million favorable adjustment to contingent consideration offset by $0.3 million of severance-related charges related to a prior year acquisition.

Patent Licenses

During the fourth quarter of fiscal 2012, we agreed to the terms of a patent license with an unrelated third party and signed an agreement on March 20, 2012.  The patent license settled alleged infringement claims.  The total payment made to the third-party in March 2012 was $2.8 million, $1.5 million of which was expensed in the fourth quarter of fiscal 2012 and the remaining $1.3 million was recorded as a prepaid royalty which will be amortized over the remaining life of the patents, which expire in December 2018.

Other Income (Expense)

Interest income in fiscal 2014 was $16.5 million compared to $15.6 million in fiscal 2013 and $18.0 million in fiscal 2012.  The primary reasons for the increase in interest income for fiscal 2014 over fiscal 2013 relates to higher yields on short-term cash investments and higher invested cash balances. The primary reasons for the decrease in interest income for fiscal 2013 over fiscal 2012 relates to lower yields on short-term cash investments and lower invested cash balances. Interest expense in fiscal 2014 was $48.7 million compared to $40.9 million in fiscal 2013 and $34.3 million in fiscal 2012. The primary reasons for the increase in interest expense over these periods relates to increased borrowings under our credit facility to partially finance our acquisition of SMSC and increased expenses associated with our larger credit facility. Other income, net in fiscal 2014 was $5.9 million compared to other expense, net of $0.4 million in fiscal 2013 and other expense, net of $0.4 million in fiscal 2012.  The primary reasons for the change in other income (expense), net during fiscal 2014 compared to fiscal 2013 relates to realized gains of $2.4 million from the sale of marketable equity and debt securities and a gain of $2.4 million recognized on a strategic investment in a company we acquired during fiscal 2014 compared to a gain of $1.3 million related to the sale of inventory previously considered discontinued during fiscal 2013 and fluctuations on our foreign currency derivatives.

Provision for Income Taxes

Our provision for income taxes reflects tax on our foreign earnings and federal and state tax on U.S. earnings.  We had an effective tax rate of 8.6% in fiscal 2014, 16.3% in fiscal 2013 and 11.3% in fiscal 2012.  Excluding certain one-time tax events described below, our effective tax rates were lower than statutory rates in the U.S. primarily due to our mix of earnings in foreign jurisdictions with lower tax rates and the R&D tax credit.  Our effective tax rate in fiscal 2014 includes $19.4 million of benefits related to various items including a settlement with the IRS for our fiscal 2009 and fiscal 2010 tax audits and the expiration of the statute of limitations on various tax reserves.  These benefits reduced our effective tax rate by 4.5 percentage points to an effective tax rate of 8.6%. During fiscal 2013, our effective tax rate was higher due to $27.2 million of one-time foreign and domestic tax implications from our acquisition of SMSC, which offset an $8.1 million benefit received from the reinstatement of the R&D credit and $9.7 million of other non-recurring tax events including releases of previously established tax reserves related to audit closures and expirations of statutes of limitations and the revaluation of deferred tax assets and liabilities. These items increased our effective tax rate by 6.2% to an effective tax rate of 16.3%. During fiscal 2012, we completed a project that led to additional R&D tax credit claims in the amount of $4.1 million which reduced our effective tax rate by 1.1% to 11.3%.

39

Various taxing authorities in the U.S. and other countries in which we do business are increasing their scrutiny of the tax structures employed by businesses.  Companies of our size and complexity are regularly audited by the taxing authorities in the jurisdictions in which they conduct significant operations.  For U.S. federal, and in general for U.S. state tax returns, our fiscal 2011 and later tax returns remain open for examination by the taxing authorities. SMSC is currently under audit for fiscal years 2011 and 2012.  We recognize liabilities for anticipated tax audit issues in the U.S. and other tax jurisdictions based on our estimate of whether, and the extent to which, additional tax payments are probable.  We believe that we maintain adequate tax reserves to offset any potential tax liabilities that may arise upon these and other pending audits in the U.S. and other countries in which we do business.  If such amounts ultimately prove to be unnecessary, the resulting reversal of such reserves would result in tax benefits being recorded in the period the reserves are no longer deemed necessary.  If such amounts ultimately prove to be less than any final assessment, a future charge to expense would be recorded in the period in which the assessment is determined.

Our Thailand manufacturing operations currently benefit from numerous tax holidays that have been granted to us by the Thailand government based on our investments in property, plant and equipment in Thailand.  Our tax holiday periods in Thailand expire at various times in the future. Any expiration of our tax holidays are expected to have a minimal impact on our overall tax expense due to other tax holidays and an increase in income in other taxing jurisdictions with lower statutory rates.

Liquidity and Capital Resources

We had $2,143.5 million in cash, cash equivalents and short-term and long-term investments at March 31, 2014, an increase of $307.5 million from the March 31, 2013 balance.  The increase in cash, cash equivalents and short-term and long-term investments over this time period is primarily attributable to cash generated by operating activities being offset in part by dividend payments of $281.2 million.

Net cash provided from operating activities was $676.6 million for fiscal 2014, $459.4 million for fiscal 2013 and $412.0 million for fiscal 2012.  The increase in cash flow from operations in fiscal 2014 compared to fiscal 2013 was primarily due to higher net sales and net income during fiscal 2014. The increase in cash flow from operations in fiscal 2013 compared to fiscal 2012 was primarily due to changes in our operating assets and liabilities.

Net cash used in investing activities was $503.3 million for fiscal 2014, $949.9 million for fiscal 2013 and $272.0 million in fiscal 2012.  The decrease in net cash used in investing activities in fiscal 2014 compared to fiscal 2013 was primarily due to our acquisition of SMSC in fiscal 2013, which used $731.7 million of cash consideration, net of $180.9 million of cash and cash equivalents acquired. This decrease in net cash used in investing activities offset a fiscal 2014 decrease in cash related to changes in our net purchases, sales and maturities of short-term and long-term investments. The increase in net cash used in investing activities in fiscal 2013 compared to fiscal 2012 was primarily due to our acquisition of SMSC in fiscal 2013.

Our level of capital expenditures varies from time to time as a result of actual and anticipated business conditions.  Capital expenditures were $113.1 million in fiscal 2014, $50.8 million in fiscal 2013 and $62.4 million in fiscal 2012.  Capital expenditures are primarily for the expansion of production capacity and the addition of research and development equipment.  We currently intend to spend approximately $125 million during the next twelve months to invest in equipment and facilities to maintain, and selectively increase, our capacity.

We expect to finance our capital expenditures through our existing cash balances and cash flows from operations.  We believe that the capital expenditures anticipated to be incurred over the next twelve months will provide sufficient manufacturing capacity to meet our currently anticipated needs.

Net cash used in financing activities was $235.0 million for fiscal 2014. Net cash provided by financing activities was $382.2million for fiscal 2013 and net cash used in financing activities was $208.1 million for fiscal 2012.  We made payments on our borrowings under our credit agreements of $1,103.5 million and $761.0 million during fiscal 2014 and fiscal 2013, respectively. Cash received on borrowings under our credit agreements totaled $1,133.5 million and $1,381.0 million during fiscal 2014 and fiscal 2013, respectively. We paid cash dividends to our stockholders of $281.2 million in fiscal 2014, $273.8 million in fiscal 2013, and $266.2 million in fiscal 2012. Proceeds from the exercise of stock options and employee purchases under our employee stock purchase plans were $37.4 million for fiscal 2014, $35.7 million for fiscal 2013 and $57.5 million for fiscal 2012.

On June 27, 2013, we entered into a $2.0 billion credit agreement with certain lenders.  The credit agreement provides for a $350.0 million term loan and a $1.65 billion revolving credit facility, with a $125 million foreign currency sublimit, a $35 million letter of credit sublimit and a $25 million swingline loan sublimit, terminating on June 27, 2018. The credit agreement also contains an increase option permitting us, subject to certain requirements, to arrange with existing lenders

40

and/or new lenders for them to provide up to an aggregate of $300 million in additional commitments, which may be for revolving loans or term loans. Proceeds of loans made under the credit agreement may be used for working capital and general corporate purposes. The new credit agreement replaced another credit agreement we had in place since August 2011. At March 31, 2014, $650.0 million of borrowings were outstanding under the credit agreement consisting of $300.0 million of a revolving line of credit and $350.0 million of a term loan, net of $1.1 million of debt discount resulting from amounts paid to the lenders.  See Note 15 of the notes to consolidated financial statements for more information regarding the credit agreement.

Our total cash, cash equivalents, short-term investments and long-term investments held by our foreign subsidiaries was $2,085.7 million at March 31, 2014 and $1,782.0 million at March 31, 2013. Under current tax laws and regulations, if accumulated earnings and profits held by our foreign subsidiaries that U.S. taxes had not previously been provided for were to be distributed to the U.S. in the form of dividends or otherwise, we would be subject to additional U.S. income taxes and foreign withholding taxes. The balance of cash, cash equivalents, short-term investments and long-term investments available for our U.S. operations as of March 31, 2014 and March 31, 2013 was approximately $57.8 million and $100.0 million, respectively. We utilize a variety of tax planning and financing strategies with the objective of having our worldwide cash available in the locations in which it is needed. We consider our offshore earnings to be permanently reinvested offshore. However, we could determine to repatriate some of our offshore earnings in future periods to fund stockholder dividends, share repurchases, acquisitions or other corporate activities.  We expect that a significant portion of our future cash generation will be in our foreign subsidiaries.

We enter into derivative transactions from time to time in an attempt to reduce our exposure to currency rate fluctuations.  Although none of the countries in which we conduct significant foreign operations have had a highly inflationary economy in the last five years, there is no assurance that inflation rates or fluctuations in foreign currency rates in countries where we conduct operations will not adversely affect our operating results in the future.  At March 31, 2014, we had no foreign currency forward contracts outstanding.

On December 11, 2007, we announced that our Board of Directors had authorized the repurchase of up to 10 million shares of our common stock in the open market or in privately negotiated transactions.  As of March 31, 2014, we had repurchased 7.5 million shares under this 10 million share authorization for a total of $234.7 million.  There is no expiration date associated with this program.  The timing and amount of future repurchases will depend upon market conditions, interest rates, and corporate considerations.

As of March 31, 2014, we held approximately 18.8 million shares as treasury shares.

On October 28, 2002, we announced that our Board of Directors had approved and instituted a quarterly cash dividend on our common stock.  The initial quarterly dividend of $0.02 per share was paid on December 6, 2003 in the amount of $4.1 million.  To date, our cumulative dividend payments have totaled approximately $2.23 billion.  During fiscal 2014, we paid dividends in the amount of $1.417 per share for a total dividend payment of $281.2 million. During fiscal 2013, we paid dividends in the amount of $1.406 per share for a total dividend payment of $273.8 million.  During fiscal 2012, we paid dividends in the amount of $1.390 per share for a total dividend payment of $266.2 million. On May 6, 2014, we declared a quarterly cash dividend of $0.3555 per share, which will be paid on June 3, 2014, to stockholders of record on May 21, 2014 and the total amount of such dividend is expected to be approximately $71.1 million.  Our Board is free to change our dividend practices at any time and to increase or decrease the dividend paid, or not to pay a dividend, on our common stock on the basis of our results of operations, financial condition, cash requirements and future prospects, and other factors deemed relevant by our Board.  Our current intent is to provide for ongoing quarterly cash dividends depending upon market conditions, our results of operations and potential changes in tax laws.

We believe that our existing sources of liquidity combined with cash generated from operations and borrowings under our credit agreement will be sufficient to meet our currently anticipated cash requirements for at least the next 12 months. However, the semiconductor industry is capital intensive.  In order to remain competitive, we must constantly evaluate the need to make significant investments in capital equipment for both production and research and development.  We may further borrow under our credit agreement or seek additional equity or debt financing from time to time to maintain or expand our wafer fabrication and product assembly and test facilities, for cash dividends or for acquisitions or other purposes.  The timing and amount of any such financing requirements will depend on a number of factors, including our level of dividend payments, changes in tax laws and regulations regarding the repatriation of offshore cash, demand for our products, changes in industry conditions, product mix, competitive factors and our ability to identify suitable acquisition candidates.  There can be no assurance that such financing will be available on acceptable terms, and any additional equity financing would result in incremental ownership dilution to our existing stockholders.

Contractual Obligations

The following table summarizes our significant contractual obligations at March 31, 2014, and the effect such obligations are expected to have on our liquidity and cash flows in future periods.  This table excludes amounts already recorded on our balance sheet as current liabilities at March 31, 2014 (dollars in thousands):

	Payments Due by Period
	Total		Less than 1 year		1 – 3 years		3 – 5 years		More than 5 years
Operating lease obligations	$	42,264	$	12,415	$	20,048	$	9,402	$	399
Capital purchase obligations (1)	42,815		42,815		—		—		—
Other purchase obligations and commitments (2)	32,654		32,586		68		—		—
Borrowings under credit agreement outstanding as of March 31, 2014 - principal and interest (3)	695,685		10,749		21,499		663,437		—
2.125% junior convertible debentures – principal and interest (4)	1,729,372		24,438		48,875		48,875		1,607,184
Total contractual obligations (5)	$	2,542,790	$	123,003	$	90,490	$	721,714	$	1,607,583

⁽¹⁾  Capital purchase obligations represent commitments for construction or purchases of property, plant and equipment.  These obligations were not recorded as liabilities on our balance sheet as of March 31, 2014, as we have not yet received the related goods or taken title to the property.

⁽²⁾  Other purchase obligations and commitments include payments due under various types of licenses and outstanding purchase commitments with our wafer foundries of approximately $31.6 million for delivery of wafers in fiscal 2015.

⁽³⁾  For purposes of this table we have assumed that the principal of our credit agreement borrowings outstanding at March 31, 2014 will be paid on June 27, 2018, which is the maturity date of such borrowings.

⁽⁴⁾  For purposes of this table we have assumed that the principal of our convertible debentures will be paid on December 31, 2037.

⁽⁵⁾  Total contractual obligations do not include contractual obligations recorded on the balance sheet as current liabilities, or certain purchase obligations as discussed below.  The contractual obligations also do not include amounts related to uncertain tax positions because reasonable estimates cannot be made.

Purchase orders or contracts for the purchase of raw materials and other goods and services, with the exception of commitments to our wafer foundries, are not included in the table above.  We are not able to determine the aggregate amount of such purchase orders that represent contractual obligations, as purchase orders may represent authorizations to purchase rather than binding agreements.  For the purpose of this table, contractual obligations for the purchase of goods or services are defined as agreements that are enforceable and legally binding on us and that specify all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the transaction.  Our purchase orders are based on our current manufacturing needs and are fulfilled by our vendors with short time horizons.  We do not have significant agreements for the purchase of raw materials or other goods specifying minimum quantities or set prices that exceed our expected requirements for three months.  We also enter into contracts for outsourced services; however, the obligations under these contracts were not significant and the contracts generally contain clauses allowing for cancellation without significant penalty.

Recently Issued Accounting Pronouncements

In May of 2014 the FASB issued Accounting Standard Update 2014-09-Revenue from Contracts with Customers, which will supersede nearly all existing revenue recognition guidance under US GAAP.  The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. We are carefully evaluating our existing revenue recognition policies to determine whether any contracts in the scope of the guidance will be affected by the new requirements.  The effects may include identifying performance obligations in existing arrangements, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation.  The new standard is effective beginning the first quarter of our 2018 fiscal year.  Early adoption is not permitted.  The standard allows for either “full retrospective” adoption, meaning the standard is applied to all of the periods presented, or “modified retrospective” adoption, meaning the standard is applied only to the most current period presented in the financial statements.  We are currently evaluating the transition method that will be elected.

In the first quarter of fiscal 2014, we adopted the provisions of Accounting Standard Update 2013-02 Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which required the disclosure of amounts reclassified out of accumulated other comprehensive income (AOCI) to net income. The adoption of this provision did not have a material impact on our consolidated financial statements and related disclosures.

Item 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our investments are intended to establish a high-quality portfolio that preserves principal, meets liquidity needs, avoids inappropriate concentrations, and delivers an appropriate yield in relationship to our investment guidelines and market conditions.  Our investment portfolio, consisting of fixed income securities, money market funds, cash deposits, and marketable securities that we hold on an available-for-sale basis, was $2,143.5million as of March 31, 2014 compared to $1,836.0 million as of March 31, 2013. The available-for-sale debt securities, like all fixed income instruments, are subject to interest rate risk and will decline in value if market interest rates increase.  We have the ability to hold our fixed income investments until maturity and, therefore, we would not expect to recognize any material adverse impact in income or cash flows if market interest rates increase.  The following table provides information about our available-for-sale securities that are sensitive to changes in interest rates.  We have aggregated our available-for-sale securities for presentation purposes since they are all very similar in nature (dollars in thousands):

	Financial instruments maturing during the fiscal year ended March 31,
	2015			2016			2017			2018			2019			Thereafter
Available-for-sale securities	$	211,363		$	364,464		$	883,305		$	51,350		$	9,995		$	150,227
Weighted-average yield rate	1.41		%	0.78		%	0.95		%	1.01		%	1.00		%	1.22		%

Item 9A.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Annual Report on Form 10-K, as required by paragraph (b) of Rule 13a-15 or Rule 15d-15 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), we evaluated under the supervision of our Chief Executive Officer and our Chief Financial Officer, the effectiveness of our disclosure controls and procedures (as

43

defined in Rules 13a-15(e) or 15d-15(e) of the Exchange Act.  Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures are effective to ensure that information we are required to disclose in reports that we file or submit under the Exchange Act (i) is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms, and (ii) is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.  Our disclosure controls and procedures are designed to provide reasonable assurance that such information is accumulated and communicated to our management.  Our disclosure controls and procedures include components of our internal control over financial reporting.  Management's assessment of the effectiveness of our internal control over financial reporting is expressed at the level of reasonable assurance because a control system, no matter how well designed and operated, can provide only reasonable, but not absolute, assurance that the control system's objectives will be met.

Management Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.  Internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.

Management assessed our internal control over financial reporting as of March 31, 2014, the end of our fiscal year.  Management based its assessment on criteria established in Internal Control – Integrated Framework (1992 framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission.  Management's assessment included evaluation of such elements as the design and operating effectiveness of key financial reporting controls, process documentation, accounting policies, and our overall control environment.  This assessment is supported by testing and monitoring performed by our finance organization.

Based on our assessment, management has concluded that our internal control over financial reporting was effective as of the end of the fiscal year to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with generally accepted accounting principles.  We reviewed the results of management's assessment with the Audit Committee of our Board of Directors.

Ernst & Young LLP, an independent registered public accounting firm, who audited our consolidated financial statements included in this Form 10-K has issued an attestation report on our internal control over financial reporting as of March 31, 2014, which is included in Part II, Item 9A.

Changes in Internal Control over Financial Reporting

During the three months ended March 31, 2014, there was no change in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Rule 13a-15 or Rule 15d-15 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of

Microchip Technology Incorporated and subsidiaries

We have audited Microchip Technology Incorporated and subsidiaries' internal control over financial reporting as of March 31, 2014, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) (the COSO criteria).  Microchip Technology Incorporated and subsidiaries' management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal Control Over Financial Reporting.  Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.  Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances.  We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.  A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Microchip Technology Incorporated and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of March 31, 2014, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the March 31, 2014 consolidated financial statements of Microchip Technology Incorporated and subsidiaries and our report dated May 30, 2014 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of

Microchip Technology Incorporated and subsidiaries

We have audited the accompanying consolidated balance sheets of Microchip Technology Incorporated and subsidiaries as of March 31, 2014 and 2013, and the related consolidated statements of income, comprehensive income, stockholders' equity, and cash flows for each of the three years in the period ended March 31, 2014.  These financial statements are the responsibility of the Company's management.  Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.  An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements.  An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Microchip Technology Incorporated and subsidiaries at March 31, 2014 and 2013, and the consolidated results of their operations and their cash flows for each of the three years in the period ended March 31, 2014, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of Microchip Technology Incorporated and subsidiaries' internal control over financial reporting as of March 31, 2014, based on criteria established in Internal Control—Integrated Framework (1992 framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated May 30, 2014 expressed an unqualified opinion thereon.

MICROCHIP TECHNOLOGY INCORPORATED AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.    SIGNIFICANT ACCOUNTING POLICIES

Nature of Business

Microchip develops, manufactures and sells specialized semiconductor products used by its customers for a wide variety of embedded control applications.  Microchip's product portfolio comprises 8-bit, 16-bit and 32-bit PIC^® microcontrollers and 16-bit dsPIC^® digital signal controllers, which feature on-board Flash (reprogrammable) memory technology.  In addition, Microchip offers a broad spectrum of high-performance linear, mixed-signal, power management, thermal management, RF, safety and security and interface devices, as well as serial EEPROMs, Serial Flash memories and Parallel Flash memories.  Microchip also licenses Flash-IP solutions that are incorporated in a broad range of products.

Principles of Consolidation

The consolidated financial statements include the accounts of Microchip Technology Incorporated and its wholly-owned subsidiaries (Microchip or the Company).  The Company does not have any subsidiaries in which it does not own 100% of the outstanding stock.  All of the Company's subsidiaries are included in the consolidated financial statements.  All significant intercompany accounts and transactions have been eliminated in consolidation.

Revenue Recognition

The Company recognizes revenue when the earnings process is complete, as evidenced by an agreement with the customer, transfer of title as well as fixed or determinable pricing and when collectability is reasonably assured.  The Company recognizes revenue from product sales to original equipment manufacturers (OEMs) upon shipment and records reserves for estimated customer returns.

Distributors worldwide generally have broad price protection and product return rights, so the Company defers revenue recognition until the distributor sells the product to their customer.  Revenue is recognized when the distributor sells the product to their end customer, at which time the sales price becomes fixed or determinable.  Revenue is not recognized upon the Company's shipment to the distributors since, due to discounts from list price as well as price protection rights, the sales price is not substantially fixed or determinable at that time.  At the time of shipment to these distributors, the Company records a trade receivable for the selling price as there is a legally enforceable right to payment, relieves inventory for the carrying value of goods shipped since legal title has passed to the distributor, and records the gross margin in deferred income on shipments to distributors on its consolidated balance sheets.

Deferred income on shipments to distributors effectively represents gross margin on the sale to the distributor at the initial shipment date; however, the amount of gross margin recognized by the Company in future periods will be less than the deferred margin as a result of credits granted to distributors on specifically identified products and customers to allow the distributors to earn a competitive gross margin on the sale of the Company's products to their end customers and price protection concessions related to market pricing conditions.

The Company sells the majority of the items in its product catalog to its distributors worldwide at a uniform list price.  However, distributors resell the Company's products to end customers at a very broad range of individually negotiated price points.  The majority of the Company's distributors' resales require a reduction from the original list price paid.  Often, under these circumstances, the Company remits back to the distributor a portion of their original purchase price after the resale transaction is completed in the form of a credit against the distributors' outstanding accounts receivable balance.  The credits are on a per unit basis and are not given to the distributor until they provide information regarding the sale to their end customer.  The price reductions vary significantly based on the customer, product, quantity ordered, geographic location and other factors and discounts to a price less than the Company's cost have historically been rare.  The effect of granting these credits establishes the net selling price from the Company to its distributors for the product and results in the net revenue recognized by the Company when the product is sold by the distributors to their end customers.  Thus, a portion of the "deferred income on shipments to distributors" balance represents the amount of distributors' original purchase price that will be credited back to the distributor in the future.  The wide range and variability of negotiated price concessions granted to distributors does not allow the Company to accurately estimate the portion of the balance in the deferred income on shipments to distributors account that will be credited back to the distributors.  Therefore, the Company does not reduce deferred income

F-7

on shipments to distributors or accounts receivable by anticipated future price concessions; rather, price concessions are recorded against deferred income on shipments to distributors when incurred, which is generally at the time the distributor sells the product.

At March 31, 2014, the Company had approximately $222.8 million of deferred revenue and $75.0 million in deferred cost of sales recognized as $147.8 million of deferred income on shipments to distributors.  At March 31, 2013, the Company had approximately $201.8 million of deferred revenue and $62.8 million of deferred cost of sales recognized as $139.0 million of deferred income on shipments to distributors.  The deferred income on shipments to distributors that will ultimately be recognized in the Company's income statement will be lower than the amount reflected on the balance sheet due to price credits to be granted to the distributors when the product is sold to their customers.  These price credits historically have resulted in the deferred income approximating the overall gross margins that the Company recognizes in the distribution channel of its business.

The Company reduces product pricing through price protection based on market conditions, competitive considerations and other factors.  Price protection is granted to distributors on the inventory they have on hand at the date the price protection is offered.  When the Company reduces the price of its products, it allows the distributor to claim a credit against its outstanding accounts receivable balances based on the new price of the inventory it has on hand as of the date of the price reduction.  There is no immediate revenue impact from the price protection, as it is reflected as a reduction of the deferred income on shipments to distributors' balance.

Products returned by distributors and subsequently scrapped have historically been immaterial to the Company's consolidated results of operations.  The Company routinely evaluates the risk of impairment of the deferred cost of sales component of the deferred income on shipments to distributors' account.  Because of the historically immaterial amounts of inventory that have been scrapped, and historically rare instances where discounts given to a distributor result in a price less than the Company's cost, the Company believes the deferred costs have a low risk of material impairment.

For license and other arrangements for SuperFlash^® technology that the Company is continuing to enhance and refine or under which it is obligated to provide unspecified enhancements, non-royalty revenue is recognized over the lesser of (1) the estimated period that the Company has historically enhanced and developed refinements to the specific technology, typically one to three years (the "upgrade period"), and (2) the remaining portion of the upgrade period after the date of delivery of all specified technology and documentation, provided that the fee is fixed or determinable and collection of the fee is reasonably assured.  Royalties received during the upgrade period are recognized as revenue based on an amortization calculation of the elapsed portion of the upgrade period compared to the entire estimated upgrade period.  Royalties received after the upgrade period has elapsed are recognized when reported to the Company, which generally coincides with the receipt of payment.  For licenses or other technology arrangements without an upgrade period, non-royalty revenue from license is recognized upon delivery of the technology if the fee is fixed or determinable and collection of the fee is reasonably assured.  Royalties are recognized when reported to the Company, which generally coincides with the receipt of payment.

Shipping charges billed to customers are included in net sales, and the related shipping costs are included in cost of sales. The Company collects and remits certain sales related taxes on sales of inventory and reports such amounts under the net method in its consolidated statements of income.

Product Warranty

The Company typically warrants its products against defects in materials and workmanship and non-conformance to specifications for 12 to 24 months.  The majority of the Company's product warranty claims are settled through the return of the defective product and the shipment of replacement product.  Warranty returns are included within the Company's allowance for returns, which is based on historical return rates.  Actual future returns could differ from the allowance established.  In addition, the Company accrues a liability for specific warranty costs expected to be settled other than through product return and replacement, if a loss is probable and can be reasonably estimated.  Product warranty expenses during fiscal 2014, 2013, and 2012 were immaterial.

Advertising Costs

The Company expenses all advertising costs as incurred.  Advertising costs were immaterial for the fiscal years ended March 31, 2014, 2013 and 2012.

F-8

Research and Development

Research and development costs are expensed as incurred.  Assets purchased to support the Company's ongoing research and development activities are capitalized when related to products which have achieved technological feasibility or that have alternative future uses and are amortized over their estimated useful lives.  Research and development expenses include expenditures for labor, share-based payments, depreciation, masks, prototype wafers, and expenses for development of process technologies, new packages, and software to support new products and design environments.

Foreign Currency Translation and Forward Contracts

The Company's foreign subsidiaries are considered to be extensions of the U.S. Company and any translation gains and losses related to these subsidiaries are included in other income (expense) in the consolidated statements of income.  As the U.S. dollar is utilized as the functional currency, gains and losses resulting from foreign currency transactions (transactions denominated in a currency other than the subsidiaries' functional currency) are also included in income.  For a portion of fiscal 2013, certain foreign subsidiaries acquired as part of the SMSC acquisition had the local currency as the functional currency. Once these entities were integrated into the Company's legal structure and intercompany agreements were executed, the U.S. dollar became the functional currency. Gains and losses associated with currency rate changes on forward contracts are recorded currently in income.  These gains and losses have been immaterial to the Company's financial statements.

Income Taxes

As part of the process of preparing its consolidated financial statements, the Company is required to estimate its income taxes in each of the jurisdictions in which it operates.  This process involves estimating the Company's actual current tax exposure together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes.  These differences result in deferred tax assets and liabilities, which are included within the Company's consolidated balance sheet.  The Company must then assess the likelihood that its deferred tax assets will be recovered from future taxable income and to the extent it believes that recovery is not likely, it must establish a valuation allowance.  The Company has provided valuation allowances for certain of its deferred tax assets where it is more likely than not that some portion, or all of such assets, will not be realized.  

Cash and Cash Equivalents

All highly liquid investments, including marketable securities purchased with a remaining maturity of three months or less when acquired are considered to be cash equivalents.

Investments – Available-for-Sale and Trading Securities

The Company classifies its investments in debt and marketable equity securities as available-for-sale or trading securities based upon management's intent with regard to the investments and the nature of the underlying securities. 

The Company's available-for-sale investments consist of government agency bonds, municipal bonds, auction rate securities (ARS), corporate bonds and marketable equity securities.  The Company's investments are carried at fair value with unrealized gains and losses reported in stockholders' equity unless losses are considered to be other than temporary impairments in which case the losses are recognized through the statement of income.  Premiums and discounts are amortized or accreted over the life of the related available-for-sale security.  Dividend and interest income are recognized when earned.  The cost of securities sold is calculated using the specific identification method. 

The Company includes within short-term investments its trading securities, as well as its income yielding available-for-sale securities that can be readily converted to cash and includes within long-term investments those income yielding available-for-sale securities with maturities of over one year that have unrealized losses attributable to them or those that cannot be readily liquidated.  Except as discussed in Note 5, the Company intends and has the ability to hold its long-term investments with temporary impairments until such time as these assets are no longer impaired.  Such recovery of unrealized losses is not expected to occur within the next year.

Non-Marketable Equity Investments

The Company's non-marketable equity investments are recorded using adjusted cost basis or the equity method of accounting, depending on the circumstances of each investment.  The Company's non-marketable equity investments are classified within other assets on the Company's consolidated balance sheet.  The Company's non-marketable equity investments include:

Equity Method Investments:  when the Company has the ability to exercise significant influence, but not control, over the investee, it records equity method gain or loss as "gain or loss from equity investments."  Equity method adjustments include the Company's proportionate share of the investee's income or loss.

Cost Method Investments:  when the Company does not have the ability to exercise significant influence over the investee, it records such investments at cost.

The Company reviews its investments quarterly for indicators of impairment.  The impairment review requires significant judgment and includes quantitative and qualitative analysis of identified events or circumstances that impact the fair value of the investment, such as:

• the investee's revenue and trends in earnings or losses relative to pre-defined milestones and overall business prospects;

• the technological feasibility of the investee's products and technologies;

• the general market conditions in the investee's industry or geographic area, including adverse regulatory or economic changes;

• factors related to the investee's ability to remain in business, such as the investee's liquidity, debt ratios, and the rate at which the investee is using its cash; and

• the investee's receipt of additional funding at a lower valuation.

If the fair value of an investment is below the Company's carrying value, the Company determines if the investment is other-than-temporarily impaired based on a quantitative and qualitative analysis, which includes assessing the severity and duration of the impairment and the likelihood of recovery before disposal.  If the investment is considered to be other-than-temporarily impaired, the Company writes down the investment to its fair value.  

Allowance for Doubtful Accounts

The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments, which is included in bad debt expense.  The Company determines the adequacy of this allowance by regularly reviewing the composition of its accounts receivable aging and evaluating individual customer receivables, considering such customer's financial condition, credit history and current economic conditions.

Inventories

Inventories are valued at the lower of cost or market using the first-in, first-out method.  The Company writes down its inventory for estimated obsolescence or unmarketable inventory in an amount equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions.  If actual market conditions are less favorable than those projected by the Company, additional inventory write-downs may be required.  Inventory impairment charges establish a new cost basis for inventory and charges are not subsequently reversed to income even if circumstances later suggest that increased carrying amounts are recoverable.  In estimating reserves for obsolescence, the Company primarily evaluates estimates of demand over a 12-month period and provides reserves for inventory on hand in excess of the estimated 12-month demand. Estimates for projected 12-month demand are generally based on the average shipments of the prior three-month period, which are then annualized to adjust for any potential seasonality in the Company's business. The estimated 12-month demand is compared to its most recently developed sales forecast to further reconcile the 12-month demand estimate. Management reviews and adjusts the estimates as appropriate based on specific situations. For example, demand can be adjusted up for new products for which historic sales are not representative of future demand. Alternatively, demand can be adjusted down to the extent any existing products are being replaced or discontinued.

In periods where the Company's production levels are substantially below normal operating capacity, unabsorbed overhead production costs associated with the reduced production levels of the Company's manufacturing facilities are charged directly to cost of sales.

F-10

Property, Plant and Equipment

Property, plant and equipment are stated at cost.  Major renewals and improvements are capitalized, while maintenance and repairs are expensed when incurred.  The Company's property and equipment accounting policies incorporate estimates, assumptions and judgments relative to the useful lives of its property and equipment.  Depreciation is provided for assets placed in service on a straight-line basis over the estimated useful lives of the relative assets, which range from 10 to 30 years for buildings and building improvements and 3 to 8 years for machinery and equipment.  The Company evaluates the carrying value of its property and equipment when events or changes in circumstances indicate that the carrying value of such assets may be impaired.  Asset impairment evaluations are, by nature, highly subjective.

Junior Subordinated Convertible Debentures

The Company separately accounts for the liability and equity components of its junior subordinated convertible debentures in a manner that reflects its nonconvertible debt (unsecured debt) borrowing rate when interest cost is recognized.  This results in a bifurcation of a component of the debt, classification of that component in equity and the accretion of the resulting discount on the debt to be recognized as part of interest expense in its consolidated statements of income.  Lastly, the Company includes the dilutive effect of the shares of its common stock issuable upon conversion of the outstanding junior subordinated convertible debentures in its diluted income per share calculation regardless of whether the market price trigger or other contingent conversion feature has been met.  The Company applies the treasury stock method as it has the intent and ability to settle the principal amount of the junior subordinated convertible debentures in cash.  This method results in incremental dilutive shares when the average market value of the Company's common stock for a reporting period exceeds the conversion price per share which was $25.87 at March 31, 2014 and adjusts as dividends are recorded in the future.

Litigation

The Company's estimated range of liability related to pending litigation is based on claims for which management believes a loss is probable and it can estimate the amount or range of loss.  Because of the uncertainties related to both the outcome and range of any potential losses on the pending litigation, the Company is generally unable to make a reasonable estimate of the liability that could result from an unfavorable outcome.  As additional information becomes available, the Company will assess the potential liability related to its pending litigation and revise its estimates, if necessary.

Business Combinations

All of the Company's business combinations are accounted for at fair value under the acquisition method of accounting.  Under the acquisition method of accounting, (i) acquisition-related costs, except for those costs incurred to issue debt or equity securities, will be expensed in the period incurred; (ii) non-controlling interests will be valued at fair value at the acquisition date; (iii) in-process research and development will be recorded at fair value as an intangible asset at the acquisition date and amortized once the technology reaches technological feasibility; (iv) restructuring costs associated with a business combination will be expensed subsequent to the acquisition date; and (v) changes in deferred tax asset valuation allowances and income tax uncertainties after the acquisition date will be recognized through income tax expense or directly in contributed capital.  The measurement of fair value of assets acquired and liabilities assumed requires significant judgment.  The valuation of intangible assets and acquired investments, in particular, requires that the Company use valuation techniques such as the income approach.  The income approach includes the use of a discounted cash flow model, which includes discounted cash flow scenarios and requires the following significant estimates:  revenue, expenses, capital spending and other costs, and discount rates based on the respective risks of the cash flows.  The valuation of non-marketable equity investments acquired also takes into account variables such as conditions reflected in the capital markets, recent financing activity by the investees, the investees' capital structure and the terms of the investees' issued interests.

Goodwill and Other Intangible Assets

Goodwill is recorded when the purchase price paid for an acquisition exceeds the estimated fair value of the net identified tangible and intangible assets acquired.  The Company is required to perform an annual impairment review, and more frequently under certain circumstances.  The goodwill is subjected to this test during the fourth quarter of the Company's fiscal year.  The Company engages primarily in the development, manufacture and sale of semiconductor products as well as technology licensing.  As a result, the Company concluded there are two reporting units, semiconductor products and technology licensing. Under the qualitative goodwill impairment assessment standard, management evaluates whether it is more likely than not that goodwill is impaired. If it is determined that it is more likely than not, the Company proceeds with the next step of the impairment test, which compares the fair value of the reporting unit to its carrying value.  If the Company determines through the impairment process that goodwill has been impaired, the Company will record the impairment charge in

F-11

its results of operation.  Through March 31, 2014, the Company has not had impaired goodwill.  The Company's other intangible assets represent existing technologies, core and developed technology, in-process research and development, trademarks and trade names, and customer-related intangibles. Other intangible assets are amortized over their respective estimated lives, ranging from one year to ten years.  In the event that facts and circumstances indicate intangibles or other long-lived assets may be impaired, the Company evaluates the recoverability and estimated useful lives of such assets.  In-process research and development is capitalized until such time the related projects are completed or abandoned at which time the capitalized amounts will begin to be amortized or written off.

Impairment of Long-Lived Assets

The Company assesses whether indicators of impairment of long-lived assets are present.  If such indicators are present, the Company determines whether the sum of the estimated undiscounted cash flows attributable to the assets in question is less than their carrying value.  If less, the Company recognizes an impairment loss based on the excess of the carrying amount of the assets over their respective fair values.  Fair value is determined by discounted future cash flows, appraisals or other methods.  If the assets determined to be impaired are to be held and used, the Company recognizes an impairment loss through a charge to operating results to the extent the present value of anticipated net cash flows attributable to the asset are less than the asset's carrying value.  The Company would depreciate the remaining value over the remaining estimated useful life of the asset.

Share-Based Compensation

The Company has equity incentive plans under which non-qualified stock options and restricted stock units (RSUs) have been granted to employees and non-employee members of the Board of Directors.  In the second half of fiscal 2006, the Company adopted RSUs as its primary equity incentive compensation instrument for employees.  The Company also has an employee stock purchase plan for all eligible employees.

The Company estimates the fair value of share-based payment awards on the date of grant using an option pricing model.  The value of the portion of the award that is ultimately expected to vest is recognized as expense ratably over the requisite service periods.  The Company has estimated the fair value of each award as of the date of grant using the Black-Scholes option pricing model, which was developed for use in estimating the value of traded options that have no vesting restrictions and that are freely transferable.  

Determining the appropriate fair-value model and calculating the fair value of share-based awards at the date of grant requires judgment.  The fair value of RSUs is based on the fair market value of the Company's common stock on the date of grant discounted for expected future dividends.  The Company uses the Black-Scholes option pricing model to estimate the fair value of employee stock options and rights to purchase shares under stock participation plans.  Option pricing models, including the Black-Scholes model, also require the use of input assumptions, including expected volatility, expected life, expected dividend rate, and expected risk-free rate of return.  The Company uses a blend of historical and implied volatility based on options freely traded in the open market as it believes this is more reflective of market conditions and a better indicator of expected volatility than using purely historical volatility.  The expected life of the awards is based on historical and other economic data trended into the future.  The risk-free interest rate assumption is based on observed interest rates appropriate for the expected terms of the Company's awards.  The dividend yield assumption is based on the Company's history and expectation of future dividend payouts.  The Company estimates the number of share-based awards which will be forfeited due to employee turnover.  Quarterly changes in the estimated forfeiture rate would affect share-based compensation, as the impact on prior period amortization for all unvested awards is recognized in the period the forfeiture estimate is changed.  If the actual forfeiture rate is higher than the estimated forfeiture rate, then an adjustment is made to increase the estimated forfeiture rate, which will result in a decrease to the expense recognized in the financial statements.  If the actual forfeiture rate is lower than the estimated forfeiture rate, then an adjustment is made to decrease the estimated forfeiture rate, which will result in an increase to the expense recognized in the financial statements.  If forfeiture adjustments are made, they would affect the Company's results of operations.  The effect of forfeiture adjustments in the years ended March 31, 2014, 2013 and 2012 was immaterial.

The Company evaluates the assumptions used to value its awards on a quarterly basis.  If factors change and the Company employs different assumptions, share-based compensation expense may differ significantly from what was recorded in the past.  If there are any modifications or cancellations of the underlying unvested securities, the Company may be required to accelerate or increase any remaining unearned share-based compensation expense.  Future share-based compensation expense and unearned share-based compensation will increase to the extent that the Company grants additional equity awards to employees or it assumes unvested equity awards in connection with acquisitions.

F-12

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of investments in debt securities and trade receivables.  Investments in debt securities with original maturities of greater than six months consist primarily of AAA and AA rated financial instruments and counterparties.  The Company's investments are primarily in direct obligations of the U.S. government or its agencies, corporate bonds, and municipal bonds.

Concentrations of credit risk with respect to accounts receivable are generally not significant due to the diversity of the Company's customers and geographic sales areas.  The Company sells its products primarily to OEMs and distributors in the Americas, Europe and Asia.  The Company performs ongoing credit evaluations of its customers' financial condition and, as deemed necessary, may require collateral, primarily letters of credit.

Distributor advances, included in deferred income on shipments to distributors in the consolidated balance sheets, totaled $92.8 million at March 31, 2014 and $70.1 million at March 31, 2013.  On sales to distributors, the Company's payment terms generally require the distributor to settle amounts owed to the Company for an amount in excess of their ultimate cost.  The Company's sales price to its distributors may be higher than the amount that the distributors will ultimately owe the Company because distributors often negotiate price reductions after purchasing the product from the Company and such reductions are often significant.  It is the Company's practice to apply these negotiated price discounts to future purchases, requiring the distributor to settle receivable balances, on a current basis, generally within 30 days, for amounts originally invoiced.  This practice has an adverse impact on the working capital of the Company's distributors.  As such, the Company has entered into agreements with certain distributors whereby it advances cash to the distributors to reduce the distributor's working capital requirements.  These advances are reconciled at least on a quarterly basis and are estimated based on the amount of ending inventory as reported by the distributor multiplied by a negotiated percentage.  Such advances have no impact on revenue recognition or the Company's consolidated statements of income.  The Company processes discounts taken by distributors against its deferred income on shipments to distributors' balance and trues-up the advanced amounts generally after the end of each completed fiscal quarter.  The terms of these advances are set forth in binding legal agreements and are unsecured, bear no interest on unsettled balances and are due upon demand.  The agreements governing these advances can be canceled by the Company at any time.

Use of Estimates

The Company has made a number of estimates and assumptions relating to the reporting of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities to prepare its consolidated financial statements in conformity with U.S. Generally Accepted Accounting Principles.  Actual results could differ from those estimates.

Recently Issued Accounting Pronouncements

In May of 2014 the FASB issued Accounting Standard Update 2014-09-Revenue from Contracts with Customers, which will supersede nearly all existing revenue recognition guidance under US GAAP.  The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The Company is carefully evaluating its existing revenue recognition policies to determine whether any contracts in the scope of the guidance will be affected by the new requirements.  The effects may include identifying performance obligations in existing arrangements, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation.  The new standard is effective beginning the first quarter of the Company’s 2018 fiscal year.  Early adoption is not permitted.  The standard allows for either “full retrospective” adoption, meaning the standard is applied to all of the periods presented, or “modified retrospective” adoption, meaning the standard is applied only to the most current period presented in the financial statements.  The Company is currently evaluating the transition method that will be elected.

In the first quarter of fiscal 2014, the Company adopted the provisions of Accounting Standard Update 2013-02 Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which required the disclosure of amounts reclassified out of accumulated other comprehensive income (AOCI) to net income. The adoption of this provision did not have a material impact on the Company's consolidated financial statements and related disclosures.

2.    BUSINESS ACQUISITIONS

On November 21, 2013, the Company completed an acquisition which was accounted for under the acquisition method of accounting. The Company had a prior 18.3% ownership interest in the acquired company accounted for as a cost method investment and recognized an approximate $2.4 million gain to write that ownership interest up to fair value in fiscal 2014. The total consideration paid for the remaining 81.7% equity of the business, net of cash acquired, was $9.0 million. The purchase price of the acquisition resulted in purchased intangible assets of $4.1 million and goodwill of approximately $6.4 million. The purchased intangible assets are being amortized over a weighted average period of approximately 8 years.

On August 2, 2012, the Company acquired SMSC, a publicly traded company based in Hauppauge, New York. The acquisition was accounted for under the acquisition method of accounting. The Company retained an independent third-party appraiser to assist management in its valuation. The table below represents the allocation of the purchase price, including adjustments to the purchase price allocation from the originally reported figures at March 31, 2013, to the net assets acquired based on their estimated fair values as of August 2, 2012. The purchase price allocation was finalized as of August 2, 2013. All adjustments shown in the table below were recorded during the three months ended June 30, 2013 (amounts in thousands):

On April 18, 2012, the Company acquired Roving Networks, a privately-held company. The acquisition was accounted for under the acquisition method of accounting.  Total consideration paid was approximately $20.6 million.  The acquisition also included contingent consideration with an estimated fair value at the date of purchase of approximately $14.7 million. During the year ended March 31, 2013, the fair value of the contingent consideration was increased to $19.1 million with the related expense of $4.4 million included in special charges. During the year ended March 31, 2014, the fair value of the contingent consideration was increased further to $20.5 million with the related expense of $1.4 million included in special charges. The contingent consideration was fully paid as of March 31, 2014. The purchase price of the acquisition resulted in purchased intangible assets of approximately $22.8 million and goodwill of approximately $8.7 million which was all allocated to the Company's semiconductor products segment.  Purchased intangible assets included $10.6 million of developed technology, $10.6 million of customer-related intangibles, $0.3 million of backlog and $1.3 million of in-process research and development. The purchased intangible assets (other than in-process technology and backlog) are being amortized over their expected useful lives which range between four and ten years. Backlog was amortized over one year and in-process research and development

is capitalized until such time the related projects are completed or abandoned at which time the capitalized amounts will begin to be amortized or written off.

On February 9, 2012, the Company acquired Ident Technology AG, a privately-held semiconductor company. The acquisition was accounted for under the acquisition method of accounting.  Total consideration paid was approximately $39.5 million.  The purchase price of the acquisition resulted in purchased intangible assets of approximately $18.1 million, of which $8.2 million related to in-process technology, and goodwill of approximately $17.4 million which was all allocated to the Company's semiconductor products segment.  Goodwill recognized in this transaction is non-deductible. The purchased intangible assets (other than goodwill and the in-process technology intangible asset) are being amortized over a period of 10 years.

3. RECLASSIFICATION OF PRIOR PERIODS

In the quarter ended December 31, 2013, the Company identified an error to the presentation on its consolidated statements of cash flows of the amortization of premium of available-for-sale investments. The Company previously included the amortization of the premium as an investing activity. This amortization is a non-cash expense that should be recorded in the adjustments to reconcile net income to net cash provided by operating activities. The Company has corrected this error in the current period, and has conformed previous periods to the current presentation. Based on the Company's evaluation of relevant quantitative and qualitative factors, it determined that the classification errors are immaterial to the prior period financial statements and the Company plans to correct the comparative presentation of the prior periods in future filings. The effect on net cash provided by operating activities and net cash used in investing activities for the previous periods covered by this report are shown below (amounts in thousands):

This correction does not affect the Company's consolidated statements of income, consolidated balance sheets, consolidated statements of comprehensive income or consolidated statements of stockholders' equity for any periods.

4.    SPECIAL CHARGES

Acquisition Related Expenses

During fiscal 2014, the Company incurred special charges of $3.0 million related to severance, office closing and other costs associated with its acquisition activity. During fiscal 2013, the Company incurred special charges of $32.2 million comprised of a $4.4 million net increase in the fair value of contingent consideration related to one of its acquisitions, $16.3 million of primarily severance-related costs in addition to office closing and other costs associated with the acquisition of SMSC and legal settlement costs of approximately $11.5 million for certain legal matters related to SST (which the Company acquired in April 2010) in excess of previously accrued amounts. During fiscal 2012, special charges included a benefit of $0.7 million of special income comprised of a $1.0 million favorable adjustment to contingent consideration offset by $0.3 million of severance-related charges related to a prior year acquisition.

Patent Licenses

During the fourth quarter of fiscal 2012, the Company agreed to the terms of a patent license with an unrelated third party and signed an agreement on March 20, 2012.  The patent license settled alleged infringement claims.  The total payment made to the third-party in March 2012 was $2.8 million, $1.5 million of which was expensed in the fourth quarter of fiscal 2012 and the remaining $1.3 million was recorded as a prepaid royalty which will be amortized over the remaining life of the patents, which expires in December 2018.

5. INVESTMENTS

The Company's investments are intended to establish a high-quality portfolio that preserves principal, meets liquidity needs, avoids inappropriate concentrations, and delivers an appropriate yield in relationship to the Company's investment guidelines and market conditions.  The following is a summary of available-for-sale securities at March 31, 2014 (amounts in thousands):

At March 31, 2014, the Company's available-for-sale debt securities are presented on the consolidated balance sheets as short-term investments of $878.2 million and long-term investments of $798.7 million.  At March 31, 2013, the Company’s available-for-sale debt securities and marketable equity securities are presented on the consolidated balance sheets as short-term investments of $1,050.3 million and long-term investments of $257.5 million.

At March 31, 2014, the Company evaluated its investment portfolio and noted unrealized losses of $4.0 million on its debt securities with an aggregated fair value of $782.7 million, which were due primarily to higher interest rates and resulting declines in market prices.  Management does not believe any of the unrealized losses represent an other-than-temporary impairment based on its evaluation of available evidence as of March 31, 2014 and the Company's intent is to hold these investments until these assets are no longer impaired, except for certain auction rate securities (ARS). For those debt securities not scheduled to mature until after March 31, 2015, such recovery is not anticipated to occur in the next year and these investments have been classified as long-term investments.

The amortized cost and estimated fair value of the available-for-sale securities at March 31, 2014, by contractual maturity, excluding corporate debt of $6.2 million, which has no contractual maturity, are shown below (amounts in thousands). Expected maturities can differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties, and the Company views its available-for-sale securities as available for current operations.

6.    FAIR VALUE MEASUREMENTS

Accounting rules for fair value clarify that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.  As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability.  As a basis for considering such assumptions, the Company utilizes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

F-17

Level 1- Observable inputs such as quoted prices in active markets;

Level 2- Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and

Level 3- Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

Marketable Debt Instruments

Marketable debt instruments include instruments such as corporate bonds and debt, government agency bonds, bank deposits, municipal bonds, and money market fund deposits. When the Company uses observable market prices for identical securities that are traded in less active markets, the Company classifies its marketable debt instruments as Level 2. When observable market prices for identical securities are not available, the Company prices its marketable debt instruments using non-binding market consensus prices that are corroborated with observable market data; quoted market prices for similar instruments; or pricing models, such as a discounted cash flow model, with all significant inputs derived from or corroborated with observable market data. Non-binding market consensus prices are based on the proprietary valuation models of pricing providers or brokers. These valuation models incorporate a number of inputs, including non-binding and binding broker quotes; observable market prices for identical or similar securities; and the internal assumptions of pricing providers or brokers that use observable market inputs and, to a lesser degree, unobservable market inputs. The Company corroborates non-binding market consensus prices with observable market data using statistical models when observable market data exists. The discounted cash flow model uses observable market inputs, such as LIBOR-based yield curves, currency spot and forward rates, and credit ratings.

There were no transfers between Level 1 and Level 2 during fiscal 2014 or fiscal 2013.

At March 31, 2014, the Company's ARS for which auctions were unsuccessful are made up of securities related to the insurance industry valued at $9.8 million with a par value of $22.4 million. At March 31, 2013, the Company's ARS for which auctions were unsuccessful were made up of bonds related to the insurance industry valued at $9.8 million, securities related to the energy and telecommunications sectors valued at $5.3 million, and student loan securities valued at $18.7 million.

The Company estimated the fair value of its ARS, which are classified as Level 3 securities, based on the following: (i) the underlying structure of each security; (ii) the present value of future principal and interest payments discounted at rates considered to reflect current market conditions; (iii) consideration of the probabilities of default, auction failure, or repurchase at par for each period; and (iv) estimates of the recovery rates in the event of default for each security. The significant unobservable inputs used in the fair value measurement of the insurance sector ARS as of March 31, 2014 were estimated risk free discount rates, liquidity risk premium, and the liquidity horizon. The risk free discount rate applied to these securities was 2% to 2.5% adjusted for the liquidity risk premium which ranged from 9.1% to 29.5%. The anticipated liquidity horizon ranged from 7 to 10 years. A significant increase in the liquidity premium or discount rate, in isolation, would lead to a significantly lower fair value measurement. A significant increase in the liquidity horizon, in isolation, would lead to a significantly lower fair value measurement. Each quarter the Company investigates material changes in the fair value measurements of its ARS.

Level 3 liabilities at March 31, 2013 include contingent consideration from the Company's Roving Networks acquisition, which was fully paid as of March 31, 2014.

The following tables present a reconciliation for all assets and liabilities measured at fair value on a recurring basis, excluding accrued interest components, using significant unobservable inputs (Level 3) for the years ended March 31, 2014 and March 31, 2013 (amounts in thousands):

Financial Assets Not Recorded at Fair Value on a Recurring Basis

The Company's non-marketable equity and cost method investments are not recorded at fair value on a recurring basis.  These investments are monitored on a quarterly basis for impairment charges.  The investments will only be recorded at fair value when an impairment charge is recognized.  During the years ended March 31, 2014 and March 31, 2013, the Company recognized impairment charges of $0.7 million and $0.5 million, respectively, on these investments. These investments are included in other assets on the consolidated balance sheet.

7.    FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amount of cash equivalents approximates fair value because their maturity is less than three months. Management believes the carrying amount of the equity and cost-method investments materially approximated fair value at March 31, 2014 based upon unobservable inputs. The fair values of these investments have been determined as Level 3 fair value measurements. The fair values of the Company's line of credit and short-term and long-term borrowings are estimated using discounted cash flow analyses, based on the Company's current incremental borrowing rates for similar types of borrowing arrangements and approximate carrying value. Based on the borrowing rates currently available to the Company for bank loans with similar terms and average maturities, the fair value of the Company's line of credit and long-term borrowings at March 31, 2014 approximated book value and are considered Level 2 in the fair value hierarchy described in Note 6. The carrying amount of accounts receivable, accounts payable and accrued liabilities approximates fair value due to the short-term maturity of the amounts.  The fair value of the Company's junior subordinated convertible debentures was $2.138 billion at March 31, 2014 and $1.639 billion at March 31, 2013 based on observable market prices for these debentures, which are traded in less active markets and are therefore classified as a Level 2 fair value measurement.

8.    ACCOUNTS RECEIVABLE

Accounts receivable consists of the following (amounts in thousands):

	March 31, 2014		March 31, 2013
Trade accounts receivable	$	243,383	$	230,469

Raw materials	$	9,734	$	9,020
Work in process	179,692		181,750
Finished goods	73,299		51,564
	$	262,725	$	242,334

Inventories are valued at the lower of cost or market using the first-in, first-out method. Inventory impairment charges establish a new cost basis for inventory and charges are not subsequently reversed to income even if circumstances later suggest that increased carrying amounts are recoverable.

10. PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment consists of the following (amounts in thousands):

	March 31, 2014		March 31, 2013
Land	$	55,624	$	47,102

The Company amortizes intangible assets over their expected useful lives, which range between 1 and 15 years.  In fiscal 2014, the Company acquired $12.7 million of developed technology which has a weighted average amortization period of 11 years, $1.3 million of customer-related intangible assets which has a weighted average amortization period of 5 years, $0.3 million of distribution rights which has a weighted average amortization period of 10 years and $0.8 million of in-process technology which will begin amortization once the technology reaches technological feasibility. The following is an expected amortization schedule for the intangible assets for fiscal 2015 through fiscal 2019, absent any future acquisitions or impairment charges (amounts in thousands):

Year ending March 31,	Projected Amortization Expense
2015	$132,951
2016	91,711
2017	61,997
2018	46,724
2019	38,730

Amortization expense attributed to intangible assets was $99.4 million, $115.8 million and $13.0 million for fiscal years 2014, 2013 and 2012, respectively.  In fiscal 2014, approximately $4.7 million was charged to cost of sales and approximately $94.7 million was charged to operating expenses.  In fiscal 2013, approximately $3.9 million was charged to cost of sales and approximately $111.9 million was charged to operating expenses.  In fiscal 2012, $1.4 million was charged to cost of sales and $11.6 million was charged to operating expenses.  The Company recognized impairment charges of $0.4 million in fiscal 2014. The Company found no indication of impairment of its intangible assets in fiscal 2013 or 2012.

Goodwill activity for fiscal years 2014 and 2013 was as follows (amounts in thousands):

	Semiconductor Products Reporting Unit			Technology Licensing Reporting Unit
Balance at March 31, 2012	$	74,313		$	19,200
Additions due to the acquisition of SMSC	169,065			—
Additions due to the acquisition of Roving Networks	8,652			—
Additions due to contingent consideration payments	118			—
Balance at March 31, 2013	252,148			19,200
Adjustments due to the acquisition of SMSC	(3,473		)	—
Additions due to other acquisitions	8,111			—
Additions due to contingent consideration payments	111			—
Balance at March 31, 2014	$	256,897		$	19,200

In fiscal 2014, the Company completed several acquisitions which resulted in goodwill of approximately $8.1 million which was allocated to the semiconductor products reporting unit. Also, during fiscal 2014, the Company made adjustments to the purchase price allocation of its SMSC acquisition of approximately $3.5 million.

F-23

In fiscal 2013, the Company acquired SMSC and Roving Networks. The SMSC acquisition resulted in approximately $169.1 million of goodwill which was allocated to the semiconductor products reporting unit. The Roving Networks acquisition resulted in approximately $8.7 million of goodwill which was allocated to the semiconductor products reporting unit.

At March 31, 2014, $256.9 million of goodwill was recorded in the Company's semiconductor products reporting unit and $19.2 million was recorded in the Company's technology licensing reporting unit. At March 31, 2014, the Company applied a qualitative goodwill impairment screen to its two reporting units, concluding it was not more likely than not that goodwill was impaired. Through March 31, 2014, the Company has never recorded an impairment charge against its goodwill balance.

12. ACCRUED LIABILITIES

Accrued liabilities consist of the following (amounts in thousands):

	March 31, 2014		March 31, 2013
Acquisition related contingent consideration	$	—	$	19,100
Other accrued expenses	96,731		108,008
	$	96,731	$	127,108

13. INCOME TAXES

The Company is subject to income taxes in the U.S. and numerous foreign jurisdictions.  The Company files U.S. federal, U.S. state, and foreign income tax returns.  For U.S. federal, and in general for U.S. state tax returns, the fiscal 2011 and later tax years remain open for examination by tax authorities.  The U.S. Internal Revenue Service (IRS) is currently auditing Microchip and SMSC's 2011 and 2012 tax years.  For foreign tax returns, the Company is generally no longer subject to income tax examinations for years prior to fiscal 2006.

Significant judgment is required in evaluating the Company's uncertain tax positions and determining its provision for income taxes.  Although the Company believes that it has appropriately reserved for its uncertain tax positions, no assurance can be given that the final tax outcome of these matters will not be different than expectations.  The Company will adjust these reserves in light of changing facts and circumstances, such as the closing of a tax audit, the refinement of an estimate, the closing of a statutory audit period or changes in applicable tax law.  To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will impact the provision for income taxes in the period in which such determination is made.  The provision for income taxes includes the impact of reserve provisions and changes to the reserves that are considered appropriate, as well as related net interest.

The Company recognizes liabilities for anticipated tax audit issues in the U.S. and other domestic and international tax jurisdictions based on its estimate of whether, and the extent to which, additional tax payments are more likely than not.  The Company believes that it has appropriate support for the income tax positions taken and to be taken on its tax returns and that its accruals for tax liabilities are adequate for all open years based on an assessment of many factors including past experience and interpretations of tax law applied to the facts of each matter.  

The Company believes it maintains appropriate reserves to offset any potential income tax liabilities that may arise upon final resolution of matters for open tax years. If such reserve amounts ultimately prove to be unnecessary, the resulting reversal of such reserves would result in tax benefits being recorded in the period the reserves are no longer deemed necessary.  If such amounts prove to be less than an ultimate assessment, a future charge to expense would be recorded in the period in which the assessment is determined.  Although the timing of the resolution and/or closure of audits is highly uncertain, the Company does not believe that it is reasonably possible that the unrecognized tax benefits would materially change in the next 12 months.

F-24

The following table summarizes the activity related to the Company's gross unrecognized tax benefits from April 1, 2011 to March 31, 2014 (amounts in thousands):

	Year Ended March 31,

As of March 31, 2014, the Company had accrued approximately $0.3 million related to the potential payment of interest on the Company's uncertain tax positions.  As of March 31, 2013, the Company had accrued approximately $3.2 million related to the potential payment of interest on the Company's uncertain tax positions. Interest was included in the provision for income taxes.  The Company has accrued for approximately $29.7 million and $30.6 million in penalties related to its uncertain tax positions related to its international locations as of March 31, 2014 and March 31, 2013, respectively.  Interest and penalties charged or (credited) to operations during the years ended March 31, 2014, 2013 and 2012 related to the Company's uncertain tax positions were $0.2 million, $0.8 million and $0.9 million, respectively.

The income tax provision consists of the following (amounts in thousands):

	Year Ended March 31,

The tax benefit associated with the Company's equity incentive plans reduced taxes currently payable by $1.4 million and $11.0 million for the years ended March 31, 2014 and 2012, respectively.  These amounts were credited to additional paid-in capital in each of these fiscal years. There was no tax benefit associated with the Company's equity incentive plans for the year ended March 31, 2013.

F-25

The provision for income taxes differs from the amount computed by applying the statutory federal tax rate to income before income taxes.  The sources and tax effects of the differences in the total income tax provision are as follows (amounts in thousands):

	Year Ended March 31,
	2014			2013			2012
Computed expected income tax provision	$	151,324		$	53,262		$	132,894
State income taxes, net of federal benefits	686			(2,054		)	1,280
Research and development tax credits - current year	(4,875		)	(8,263		)	(3,750		)
Research and development tax credits - prior years	1,600			(3,347		)	(5,894		)
Foreign income taxed at lower than the federal rate	(116,003		)	(61,377		)	(97,169		)
Increases related to current and prior year tax positions	16,809			44,661			14,518
Decreases related to prior year tax positions (1)	(14,581		)	(7,154		)	(2,153		)
Withholding taxes	6,212			7,267			6,995
Other	(4,099		)	1,793			(3,731		)
	$	37,073		$	24,788		$	42,990

⁽¹⁾ The release of prior year tax positions during fiscal 2014 increased each of the current year basic and diluted net income per common share by $0.07. The release of prior year tax positions during fiscal 2013 increased the current year basic and diluted net income per common share by $0.04 and $0.03, respectively. The release of prior year tax positions during fiscal 2012 increased each of the current year basic and diluted net income per common share by $0.01.

Pretax income from foreign operations was $404.1 million, $234.3 million and $328.5 million for the years ended March 31, 2014, 2013 and 2012, respectively.  Unremitted foreign earnings that are considered to be permanently invested outside the U.S., and on which no deferred taxes have been provided, amounted to approximately $2.4 billion at March 31, 2014.  The Company has the ability and intent to indefinitely reinvest its foreign earnings.  Should the Company elect in the future to repatriate a portion of the foreign earnings so invested, the Company would incur income tax expense on such repatriation, net of any available deductions and foreign tax credits.  This would result in additional income tax expense beyond the computed effective tax rate in such periods.

During the year ended March 31, 2014, the Company settled an IRS examination of fiscal years 2009 and 2010.  In addition, the Company benefited from the expiration of the statute of limitations and other releases related to previously accrued tax reserves.  The total tax benefit associated with these items resulted in a reduction of income tax provision of approximately $14.6 million and a decrease in the effective tax rate of 3.4%.

In January 2013, the U.S. Congress retroactively reinstated the research and development tax credit from January 1, 2012.  As a result, the Company recognized a one-time tax benefit of $8.1 million in the year ended March 31, 2013 related to the reinstatement of the credit for calendar year 2012.

In addition to the deferred tax assets listed above, the Company has unrecorded tax benefits of $29.8 million attributable to the difference between the amount of the financial statement expense and the allowable tax deduction associated with share-based compensation. As a result of net operating loss (NOL) carryforwards, the Company was not able to recognize the excess tax benefits of share-based compensation deductions because the deductions did not reduce income tax payable. Although not recognized for financial reporting purposes, this unrecorded tax benefit is available to reduce future income and is incorporated into the disclosed amounts of the Company's federal and state NOL carryforwards, discussed below. If subsequently realized, the benefit will be recorded to contributed capital.

The Company had federal, state and foreign NOL carryforwards with an estimated tax effect of $110.6 million available at March 31, 2014.  The federal and state NOL carryforwards expire at various times between 2015 and 2034.  The Company believes that it is more likely than not that the benefit from certain foreign and state NOL carryforwards will not be realized.  In recognition of this risk, at March 31, 2014, the Company has provided a valuation allowance of $20.5 million.  The Company also has state tax credits with an estimated tax effect of $54.3 million available at March 31, 2014.  These state tax credits expire at various times between 2015 and 2034.  The Company believes that it is more likely than not that the full benefit from these state tax credits will not be realized, and therefore has provided a valuation allowance of $51.4 million.  The Company has U.S foreign tax credits with an estimated tax effect of $21.9 million that expire at various times between 2015 and 2024.  The Company believes it is more likely than not that the benefit from these credits will not be fully realized and has provided a valuation allowance of $21.8 million.  At March 31, 2014, the Company had credits for increasing research activity in the amount of $44.4 million that expire at various times between 2021 and 2034. In addition, the Company had $3.7 million of alternative minimum tax credits that do not expire. At March 31, 2014, the Company had alternative minimum tax NOL carryforwards of approximately $308.0 million that expire between 2032 and 2034.

F-27

The Company's Thailand manufacturing operations currently benefit from numerous tax holidays granted to the Company based on its investment in property, plant and equipment in Thailand.  The Company's tax holiday periods in Thailand expire at various times in the future, however, the Company actively seeks to acquire new tax holidays.  The Company does not expect the future expiration of any of its tax holiday periods in Thailand to have a material impact on its effective tax rate.  The aggregate dollar benefits derived from these tax holidays approximated $16.8 million, $12.0 million and $6.5 million in fiscal 2014, 2013 and 2012, respectively.  The benefit the tax holiday had on diluted net income per share approximated $0.08 in fiscal 2014, $0.06 in fiscal 2013 and $0.03 in fiscal 2012.

On September 13, 2013, the IRS and the Treasury Department released final regulations under Section 162(a) and 263(a) on the deduction and capitalization of expenditures related to tangible property. The new regulations apply to tax years beginning on or after January 1, 2014; therefore they had no material impact on fiscal 2014. The Company believes that no material impact will result from these new regulations (specifically given the Company’s NOL position), but the Company is in the process of evaluating the full impact of these changes.

14.    2.125% JUNIOR SUBORDINATED CONVERTIBLE DEBENTURES

The Company's $1.15 billion principal amount of 2.125% junior subordinated convertible debentures due December 15, 2037, are subordinated in right of payment to any future senior debt of the Company and are effectively subordinated in right of payment to the liabilities of the Company's subsidiaries.  The debentures are convertible, subject to certain conditions, into shares of the Company's common stock at an initial conversion rate of 29.2783 shares of common stock per $1,000 principal amount of debentures, representing an initial conversion price of approximately $34.16 per share of common stock.  As of March 31, 2014, the holders of the debentures have the right to convert their debentures between April 1, 2014 and June 30, 2014 because for at least 20 trading days during the 30 consecutive trading day period ending on March 31, 2014, the Company's common stock had a last reported sale price greater than 130% of the conversion price. As of March 31, 2014, a holder could realize more economic value by selling its debentures in the over the counter market than from converting its debentures.  As a result of cash dividends paid since the issuance of the debentures, the conversion rate has been adjusted to 38.6588 shares of common stock per $1,000 of principal amount of debentures, representing a conversion price of approximately $25.87 per share of common stock. The debentures include a contingent interest mechanism that begins in December 2017. The terms of the contingent interest include a 0.25% interest rate if the debentures are trading at less than $40 and 0.5% if the debentures are trading at greater than $150. Based on the current trading price of the debentures the contingent interest rate in calendar year 2017 would be 0.5%.

As the debentures can be settled in cash upon conversion, for accounting purposes, the debentures were bifurcated into a liability component and an equity component, which are both initially recorded at fair value.  The carrying value of the equity component at March 31, 2014 and at March 31, 2013 was $822.4 million.  The estimated fair value of the liability component of the debentures at the issuance date was $327.6 million, resulting in a debt discount of $822.4 million.  The unamortized debt discount was $777.2 million at March 31, 2014 and $786.2 million at March 31, 2013.  The carrying value of the debentures was $371.9 million at March 31, 2014 and $363.4 million at March 31, 2013.  The remaining period over which the unamortized debt discount will be recognized as non-cash interest expense is 23.75 years.  In the years ended March 31, 2014, 2013 and 2012 the Company recognized $9.0 million, $8.2 million and $7.5 million, respectively, in non-cash interest expense related to the amortization of the debt discount.  The Company recognized $24.4 million of interest expense related to the 2.125% coupon on the debentures in each of fiscal 2014, fiscal 2013 and fiscal 2012.

15. CREDIT FACILITY

On June 27, 2013, the Company entered into a $2.0 billion credit agreement among the Company, the lenders from time to time that are parties thereto and JPMorgan Chase Bank, N.A., as administrative agent (the Credit Agreement). The Credit Agreement provides for a $350 million term loan and a $1.65 billion revolving credit facility, with a $125 million foreign currency sublimit, a $35 million letter of credit sublimit and a $25 million swingline loan sublimit, terminating on June 27, 2018 (the Maturity Date). The Credit Agreement also contains an increase option permitting the Company, subject to certain requirements, to arrange with existing lenders and/or new lenders for them to provide up to an aggregate of $300 million in additional commitments, which may be for revolving loans or term loans. Proceeds of loans made under the Credit Agreement may be used for working capital and general corporate purposes. The Credit Agreement replaced another credit agreement the Company had in place since August 2011. At March 31, 2014, $650.0 million of borrowings were outstanding under the Credit Agreement consisting of $300 million of a revolving line of credit and $350 million of a term loan, net of $1.1 million of debt discount resulting from amounts paid to the lenders. The repayment schedule for the term loan portion of the Credit Agreement outstanding at March 31, 2014 is as follows (amounts in thousands):

F-28

Year Ending March 31,	Amount
2015	$	17,500
2016	17,500
2017	35,000
2018	35,000
2019	245,000
Total	$	350,000

The loans under the Credit Agreement bear interest, at the Company's option, at the base rate plus a spread of 0.25% to 1.25% or an adjusted LIBOR rate (based on one, two, three, or six-month interest periods) plus a spread of 1.25% to 2.25%, in each case with such spread being determined based on the consolidated leverage ratio for the preceding four fiscal quarter period. The base rate means the highest of JPMorgan Chase Bank, N.A.'s prime rate, the federal funds rate plus a margin equal to 0.50% and the adjusted LIBOR rate for a 1-month interest period plus a margin equal to 1.00%. Swingline loans accrue interest at a per annum rate based on the base rate plus the applicable margin for base rate loans. Base rate loans may only be made in U.S. Dollars. The Company is also obligated to pay other administration fees and letter of credit fees for a credit facility of this size and type.

Interest is due and payable in arrears quarterly for loans bearing interest at the base rate and at the end of an interest period (or at each three month interval in the case of loans with interest periods greater than three months) in the case of loans bearing interest at the adjusted LIBOR rate. Interest expense related to the Credit Agreement was approximately $14.6 million in fiscal 2014. Interest expense related to the Company's prior credit agreement was approximately $7.0 million in fiscal 2013 and approximately $3.3 million in fiscal 2012. Principal, together with all accrued and unpaid interest, is due and payable on the Maturity Date. The weighted average interest rate on short-term borrowings outstanding at March 31, 2014 related to the credit agreement was 1.65%. The Company also pays a quarterly commitment fee on the available but unused portion of its line of credit which is calculated on the average daily available balance during the period. The Company may prepay the loans and terminate the commitments, in whole or in part, at any time without premium or penalty, subject to certain conditions including minimum amounts in the case of commitment reductions and reimbursement of certain costs in the case of prepayments of LIBOR loans.

The Company's obligations under the Credit Agreement are guaranteed by certain of its subsidiaries meeting materiality thresholds set forth in the Credit Agreement. To secure the Company's obligations under the Credit Agreement, the Company and its domestic subsidiaries will be required to pledge the equity securities of certain of their respective material subsidiaries, subject to certain exceptions and limitations.

The Credit Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict the Company and its subsidiaries' ability to, among other things, incur subsidiary indebtedness, grant liens, merge or consolidate, dispose of assets, make investments, make acquisitions, enter into certain transactions with affiliates, pay dividends or make distributions, repurchase stock, enter into restrictive agreements and enter into sale and leaseback transactions, in each case subject to customary exceptions for a credit facility of this size and type. The Company is also required to maintain compliance with a consolidated leverage ratio and a consolidated interest coverage ratio. At March 31, 2014, the Company was in compliance with these covenants.

The Credit Agreement includes customary events of default that include, among other things, non-payment defaults, inaccuracy of representations and warranties, covenant defaults, cross default to material indebtedness, bankruptcy and insolvency defaults, material judgment defaults, ERISA defaults and a change of control default. The occurrence of an event of default could result in the acceleration of the obligations under the Credit Agreement. Under certain circumstances, a default interest rate will apply on all obligations during the existence of an event of default under the Credit Agreement at a per annum rate equal to 2.00% above the applicable interest rate for any overdue principal and 2.00% above the rate applicable for base rate loans for any other overdue amounts.

16. CONTINGENCIES

In the ordinary course of the Company's business, it is involved in a limited number of legal actions, both as plaintiff and defendant, and could incur uninsured liability in any one or more of them.  The Company also periodically receives notifications from various third parties alleging infringement of patents, intellectual property rights or other matters.  With respect to pending legal actions to which the Company is a party, although the outcomes of these actions are not generally determinable, the Company believes that the ultimate resolution of these matters will not have a material adverse effect on its financial position, cash flows or results of operations.  Litigation relating to the semiconductor industry is not uncommon, and the Company is, and from time to time has been, subject to such litigation.  No assurances can be given with respect to the extent or outcome of any such litigation in the future.

The Company's technology license agreements generally include an indemnification clause that indemnifies the licensee against liability and damages (including legal defense costs) arising from any claims of patent, copyright, trademark or trade secret infringement by the Company's proprietary technology.  The terms of these indemnification provisions approximate the terms of the outgoing technology license agreements, which are typically perpetual unless terminated by either party for breach. The possible amount of future payments the Company could be required to make based on agreements that specify indemnification limits, if such indemnifications were required on all of these agreements, is approximately $129 million. There are some licensing agreements in place that do not specify indemnification limits.  The Company had not recorded any liabilities related to these indemnification obligations as of March 31, 2014.

Contingent liabilities in the amount of $13.0 million were recorded in connection with the Company's April 8, 2010 acquisition of Silicon Storage Technology Inc. (SST) as an adverse outcome was determined to be probable and estimable.  One of the contingent liabilities associated with the SST acquisition was resolved in fiscal 2013 with legal settlement costs of approximately $11.5 million in excess of previously accrued amounts, which were expensed as special charges in the statement of income. At March 31, 2014, $5.7 million of the original contingent liabilities recorded were still outstanding.

17.STOCK REPURCHASE ACTIVITY

On December 11, 2007, the Company announced that its Board of Directors had authorized the repurchase of up to 10.0 million shares of its common stock in the open market or in privately negotiated transactions.  As of March 31, 2014, the Company had repurchased 7.5 million shares under this authorization for $234.7 million.  There is no expiration date associated with this program.

During the years ended March 31, 2014, 2013 and 2012, the Company did not purchase any of its shares of common stock. 

18.EMPLOYEE BENEFIT PLANS

The Company maintains a contributory profit-sharing plan for its domestic employees meeting certain eligibility and service requirements.  The plan qualifies under Section 401(k) of the Internal Revenue Code of 1986, as amended, and allows employees to contribute up to 60% of their base salary, subject to maximum annual limitations prescribed by the IRS.  The Company has a discretionary matching contribution program. All matches are provided on a quarterly basis and require the participant to be an active employee at the end of each quarter.  For fiscal 2014, the Company contributions to the plan totaled $3.6 million.  For fiscal 2013, the Company contributions to the plan totaled $0.8 million. For fiscal 2012, the Company contributions to the plan totaled $1.6 million.

The Company's 2001 Employee Stock Purchase Plan (the 2001 Purchase Plan) became effective on March 1, 2002.  The Board of Directors approved the 2001 Purchase Plan in May 2001 and the stockholders approved it in August 2001.  Under the 2001 Purchase Plan, eligible employees of the Company may purchase shares of common stock at semi-annual intervals through periodic payroll deductions.  The purchase price in general will be 85% of the lower of the fair market value of the common stock on the first day of the participant's entry date into the offering period or of the fair market value on the semi-annual purchase date.  Depending upon a participant's entry date into the 2001 Purchase Plan, purchase periods under the 2001 Purchase Plan consist of overlapping periods of either 24, 18, 12 or 6 months in duration.  In May 2003 and August 2003, the Company's Board and stockholders, respectively, each approved an annual automatic increase in the number of shares reserved under the 2001 Purchase Plan.  The automatic increase took effect on January 1, 2005, and on each January 1 thereafter during the term of the plan, and is equal to the lesser of (i) 1,500,000, (ii) one half of one percent (0.5%) of the then outstanding shares of the Company's common stock, or (iii) such lesser amount as is approved by Board of Directors.  Upon the approval of the Board of Directors, there were no shares added under the 2001 Purchase Plan on January 1, 2014 or January 1, 2013 based on the automatic increase provision. On January 1, 2012, an additional 960,269 shares were reserved under the 2001 Purchase

F-30

Plan based on the automatic increase.  Since the inception of the 2001 Purchase Plan, 11,277,862 shares of common stock have been reserved for issuance and 5,641,704 shares have been issued under this purchase plan.

During fiscal 1995, a purchase plan was adopted for employees in non-U.S. locations.  Such plan provided for the purchase price per share to be 100% of the lower of the fair market value of the common stock at the beginning or end of the semi-annual purchase plan period.  Effective May 1, 2006, the Company's Board approved a purchase price per share equal to 85% of the lower of the fair market value of the common stock at the beginning or end of the semi-annual purchase plan period.  Since the inception of this purchase plan, 1,500,285 shares of common stock have been reserved for issuance and 830,277 shares have been issued under this purchase plan.

Effective January 1, 1997, the Company adopted a non-qualified deferred compensation arrangement.  This plan is unfunded and is maintained primarily for the purpose of providing deferred compensation for a select group of highly compensated employees as defined in ERISA Sections 201, 301 and 401.  There are no Company matching contributions made under this plan.

In connection with the acquisition of SMSC, the Company assumed an unfunded Supplemental Executive Retirement Plan ("SERP"), which provides former SMSC senior management with retirement, disability and death benefits. An amendment to the SERP was executed on November 3, 2009, freezing the benefit level for existing participants as of February 28, 2010 and closing the SERP to new participants. As of March 31, 2014, the projected benefit obligation is $6.3 million. Annual benefit payments and contributions under this plan are expected to be approximately $0.8 million in fiscal 2015 and approximately $4.5 million cumulatively in fiscal 2016 through fiscal 2024.

The Company has management incentive compensation plans which provide for bonus payments, based on a percentage of base salary, from an incentive pool created from operating profits of the Company, at the discretion of the Board of Directors.  During fiscal 2014, 2013 and 2012, $24.4 million, $12.0 million and $7.8 million were charged against operations for these plans, respectively.

The Company also has a plan that, at the discretion of the Board of Directors, provides a cash bonus to all employees of the Company based on the operating profits of the Company.  During fiscal 2014, 2013 and 2012, $15.2 million, $4.3 million and $3.2 million, respectively, were charged against operations for this plan.

During the year ended March 31, 2012, $6.6 million of share-based compensation expense was capitalized to inventory, and $5.6 million of previously capitalized share-based compensation expense in inventory was sold.

F-31

The amount of unearned share-based compensation currently estimated to be expensed in the remainder of fiscal 2015 through fiscal 2019 related to unvested share-based payment awards at March 31, 2014 is $83.5 million.  The weighted average period over which the unearned share-based compensation is expected to be recognized is approximately 2.01 years.

SMSC Acquisition-related Equity Awards

In connection with the acquisition of SMSC in fiscal 2013, the Company recognized $7.8 million in share-based compensation expense due to the accelerated vesting of outstanding equity awards upon termination of certain SMSC executive officers. Also, in connection with the acquisition of SMSC, the Company assumed certain unvested stock options, stock appreciation rights (SARs) and RSUs granted by SMSC. The assumed awards were measured at the acquisition date based on the estimated fair value, which was a total of $28.2 million. The Hull White II lattice model was used to value the assumed awards. A portion of that fair value, $6.9 million, which represented the preacquisition vested service provided by employees to SMSC, was included in the total consideration transferred as part of the acquisition. As of the acquisition date, the remaining portion of the fair value of those awards was $21.3 million, representing post-acquisition stock-based compensation expense that would be recognized as these employees provide service over the remaining vesting periods.

21. GEOGRAPHIC AND SEGMENT INFORMATION

The Company's reporting segments include semiconductor products and technology licensing.  The Company does not allocate operating expenses, interest income, interest expense, other income or expense, or provision for or benefit from income taxes to these segments for internal reporting purposes, as the Company does not believe that allocating these expenses is beneficial in evaluating segment performance.  Additionally, the Company does not allocate assets to segments for internal reporting purposes as it does not manage its segments by such metrics.

The following table represents revenues and gross profit for each segment (amounts in thousands):

The Company sells its products to distributors and original equipment manufacturers (OEMs) in a broad range of market segments, performs on-going credit evaluations of its customers and, as deemed necessary, may require collateral, primarily letters of credit.  The Company's operations outside the U.S. consist of product assembly and final test facilities in Thailand, and sales and support centers and design centers in certain foreign countries.  Domestic operations are responsible for the design, development and wafer fabrication of products, as well as the coordination of production planning and shipping to meet worldwide customer commitments.  The Company's Thailand assembly and test facility is reimbursed in relation to value added with respect to assembly and test operations and other functions performed, and certain foreign sales offices receive compensation for sales within their territory.  Accordingly, for financial statement purposes, it is not meaningful to segregate sales or operating profits for the assembly and test and foreign sales office operations.  Identifiable long-lived assets (consisting of property, plant and equipment net of accumulated amortization) by geographic area are as follows (amounts in thousands):

	March 31,
	2014		2013
United States	$	311,926	$	325,326

Total long-lived assets	$	531,967	$	514,544

Sales to unaffiliated customers located outside the U.S., primarily in Asia and Europe, aggregated approximately 84%, 83% and 82% of consolidated net sales for fiscal 2014, 2013 and 2012, respectively.  Sales to customers in Europe represented 21%, 22% and 23% of consolidated net sales for fiscal 2014, 2013 and 2012, respectively.  Sales to customers in Asia represented 60%, 58% and 56% of consolidated net sales for fiscal 2014, 2013 and 2012, respectively.  Within Asia, sales into China, including Hong Kong, represented 29%, 27% and 24% of consolidated net sales for fiscal 2014, 2013 and 2012, respectively.  Sales into Taiwan represented 13% of consolidated net sales in each of fiscal 2014 and 2013. Sales into Taiwan represented 15% of consolidated net sales for fiscal 2012.  Sales into any other individual foreign country did not exceed 10% of the Company's net sales for any of the years presented.

No single end customer accounted for 10% or more of the Company's net sales during fiscal 2014, 2013 or 2012. Future Electronics, one of the Company's distributors, accounted for approximately 10% of the Company's net sales in fiscal 2012. These net sales are reported in the semiconductor products segment. No other distributor accounted for 10% or more of the Company's net sales in fiscal 2014 or fiscal 2013.

22. DERIVATIVE INSTRUMENTS

The Company has international operations and is thus subject to foreign currency rate fluctuations.  To help manage the risk of changes in foreign currency rates, the Company periodically enters into derivative contracts comprised of foreign currency forward contracts to hedge its asset and liability foreign currency exposure and a portion of its foreign currency operating expenses.  Approximately 99% of the Company's sales are U.S. Dollar denominated.  To date, the exposure related to foreign exchange rate volatility has not been material to the Company's operating results.  As of March 31, 2014, the Company had no foreign currency forward contracts outstanding. As of March 31, 2013, the Company had a foreign currency forward contract outstanding with a notional amount of $6.0 million to economically hedge certain balance sheet exposures related to the Japanese yen. The fair value of this contract was immaterial as of March 31, 2013. The Company recognized an immaterial amount of net realized gains and losses on foreign currency forward contracts in the years ended March 31, 2014, 2013 and 2012. Gains and losses from changes in the fair value of these foreign currency forward contracts are credited or charged to Other Income (Expense). The Company does not apply hedge accounting to its foreign currency derivative instruments.

23. NET INCOME PER COMMON SHARE

The following table sets forth the computation of basic and diluted net income per common share (in thousands, except per share amounts):

	Year ended March 31,

Diluted net income per common share	$	1.82	$	0.62	$	1.65

Diluted net income per common share for fiscal 2014, 2013, and 2012 includes 15,429,003, 7,531,111 and 8,029,255 shares, respectively, issuable upon the exchange of debentures (see Note 14).  The debentures have no impact on diluted net income per common share unless the average price of the Company's common stock exceeds the conversion price because the principal amount of the debentures will be settled in cash upon conversion.  Prior to conversion, the Company will include, in the diluted net income per common share calculation, the effect of the additional shares that may be issued when the Company's common stock price exceeds the conversion price using the treasury stock method.  The weighted average conversion price per share used in calculating the dilutive effect of the convertible debt for fiscal 2014, 2013 and 2012 was $26.32, $27.36 and $28.50, respectively. 

Weighted average common shares exclude the effect of option shares which are not dilutive.  There were no antidilutive option shares for fiscal 2014. For fiscal 2013 and 2012, the number of option shares that were antidilutive was 98,068 and 53,374, respectively.

EFFECT ON THE CAPITAL STOCK OF THE

CONSTITUENT CORPORATIONS

Section 4.1Conversion of Capital Stock.

At the Closing Date, by virtue of the Merger and without any action on the part of the Company, Merger Sub or the holders of any shares of capital stock of the Company or Merger Sub:

(a)Each Share issued and outstanding immediately prior to the Closing Date (other than Shares to be canceled in accordance with Section 4.1(b) and other than any Dissenting Shares as defined in Section 4.5 hereof), shall thereupon be converted automatically into, and shall thereafter represent, the right to receive NT$143 in cash without interest, and subject to deduction for any required withholding Tax and any adjustment pursuant to Section 4.6 (the "Merger Consideration"). From and after the Closing Date, all such Shares shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of such a Share shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration therefor upon the surrender of such Share in accordance with Section 4.3.

(b)Each Share owned by Merger Sub or by the Company immediately prior to the Closing Date shall automatically be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor.

Section 4.2Treatment of Options.

(a)At the Closing Date, each option (each, a "Company Stock Option") to purchase Shares granted under any employee, consultant, representative or director stock option, stock purchase or equity compensation plan, arrangement or agreement of the Company or any of its Subsidiaries (collectively, the "Company Equity Plans") that is exercisable and outstanding immediately prior to the Closing Date, taking into account any acceleration of exercisability that occurs, pursuant to the applicable award agreement, as a result of the transactions contemplated by this Agreement, shall be canceled and, in exchange therefor (and in full satisfaction thereof), the Surviving Corporation shall pay, to each Person who, at the time of such cancellation, was holding any such canceled Company Stock Option as soon as practicable following the Closing Date an amount in cash (without interest, and subject to deduction for any required withholding Taxes where applicable under any provision of any tax Laws and regulations) equal to the product of (i) the

10

excess (if any) of the Merger Consideration over the exercise price per Share under such Company Stock Option and (ii) the number of Shares subject to such Company Stock Option; provided, that if the exercise price per Share under any such Company Stock Option is equal to or greater than the Merger Consideration, then such Company Stock Option shall be canceled without any cash payment being made in respect thereof.

(b)At the Closing Date, each Company Stock Option that is outstanding and unexercisable immediately prior to the Closing Date, taking into account any acceleration of exercisability that occurs, pursuant to the applicable award agreement, as a result of the transactions contemplated by this Agreement (each, an "Outstanding Unexercisable Company Option"), shall be converted into and become an option to purchase Parent common stock, with such conversion effected through Parent: (i) assuming such Outstanding Unexercisable Company Option; or (ii) replacing such Outstanding Unexercisable Company Option by issuing a reasonably equivalent replacement stock option to purchase Parent common stock in substitution therefor, in either case in accordance with the terms (as amended in accordance with the terms of this Agreement) of the applicable Company Equity Plan and the terms of the stock option agreement by which such Outstanding Unexercisable Company Option is evidenced. All rights with respect to Shares under Outstanding Unexercisable Company Options assumed or replaced by Parent shall thereupon be converted into options with respect to Parent common stock. Accordingly, from and after the Closing Date: (A) each Outstanding Unexercisable Company Option assumed or replaced by Parent may be exercised solely for shares of Parent common stock; (B) the number of shares of Parent common stock subject to each Outstanding Unexercisable Company Option assumed or replaced by Parent shall be determined by multiplying the number of Shares that were subject to such Outstanding Unexercisable Company Option immediately prior to the Closing Date by the Conversion Ratio (as defined below), and rounding the resulting number down to the nearest whole number of shares of Parent common stock; (C) the per share exercise price for the Parent common stock issuable upon exercise of each Outstanding Unexercisable Company Option assumed or replaced by Parent shall be determined by dividing the per share exercise price of the Shares subject to such Outstanding Unexercisable Company Option, as in effect immediately prior to the Closing Date Time, by the Conversion Ratio, and rounding the resulting exercise price up to the nearest whole cent; and (D) subject to the terms of the stock option agreement by which such Outstanding Unexercisable Company Option is evidenced, any restriction on the exercise of any Outstanding Unexercisable Company Option assumed or replaced by Parent shall continue in full force and effect and the term, exercisability, vesting schedule and other provisions of such Outstanding Unexercisable Company Option shall, subject to the actions described in Section 7.13, otherwise remain unchanged as a result of the assumption or replacement of such Outstanding Unexercisable Company Option; provided, however, that (I) the board of directors of Parent or a committee thereof shall succeed to the authority and responsibility of the Company Board or any committee thereof with respect to each Outstanding Unexercisable Company Option assumed or replaced by Parent and (II) Parent may modify certain of the provisions in such Outstanding Unexercisable Company Options to conform to the practices under Parent's equity compensation plans. The "Conversion Ratio" shall be equal to the fraction having a numerator equal to the US Dollar equivalent of the Merger Consideration determined as of the Closing Date, which represents the fair market value of a Share as of the Closing Date, and having a denominator equal to the average of the closing sale prices of a share of Parent common stock as reported on the NASDAQ Global Select Market for each of the

11

ten consecutive trading days immediately preceding the Closing Date (the "Average Parent Stock Price"); provided, however, that if, between the date of this Agreement and the Closing Date, the outstanding Shares or Parent common stock are changed into a different number or class of shares by reason of any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction, then the Conversion Ratio shall be adjusted equitably and proportionately to the extent appropriate to preserve the intended consequences of the adjustment.

Section 4.3Payment.

(a)At or prior to the Closing Date, Merger Sub shall deliver or cause to be delivered to the Company's stock agent (the "Stock Agent") cash in an amount sufficient to pay the aggregate Merger Consideration in accordance with Section 4.1(a) (the "Payment Fund"). The Stock Agent shall make payments of the aggregate Merger Consideration out of the Payment Fund in accordance with this Agreement. The Payment Fund shall not be used for any purpose other than to fund payments due pursuant to Section 4.1(a). The Surviving Corporation shall pay all charges and expenses, including those of the Stock Agent, incurred by them in connection with the payment of the Merger Consideration and other amounts contemplated by this Article IV.

(b)As soon as reasonably practicable on or after the Closing Date, the Surviving Corporation shall cause the Stock Agent to pay the Merger Consideration to each holder of record of uncertificated Shares represented by book-entry ("Book-Entry Shares"). After paying the Merger Consideration to each of the holder of the Book-Entry Shares, the Stock Agent shall apply with the Taiwan Depository & Clearing Corporation to cancel the Book-Entry Shares. The Merger Consideration shall be paid to the Person whose name is registered as the holder of the Shares. Each Book-Entry Share shall be deemed at any time after the Closing Date to represent only the right to receive upon such surrender or transfer the Merger Consideration pursuant to Section 4.1(a) payable in respect of Shares theretofore represented by such Book-Entry Shares, as applicable, without any interest thereon.

(c)The payment of the applicable Merger Consideration in accordance with the terms of this Article IV shall be deemed to have been delivered and paid in full satisfaction of all rights pertaining to the Shares formerly represented by such Book-Entry Shares. Two (2) business days prior to the lock-up period for the Closing, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers on the stock transfer books of the Shares of the Company.

(d)Any portion of the Payment Fund (and any interest or other income earned thereon) that remains undistributed to the holders of Book-Entry Shares nine months after the Closing Date shall be delivered to the Surviving Corporation upon demand, and any holders of Shares who have not theretofore complied with this Article IV shall thereafter look only to the Surviving Corporation, as general creditors thereof, for payment of the Merger Consideration with respect to Shares formerly represented by such Book-Entry Share, without interest.

Section 4.4Withholding Rights.

12

To fulfill applicable Tax compliance requirements after the Closing Date, the Company and the Surviving Corporation have agreed that, where applicable under any provision of any tax Laws and regulations, the Surviving Corporation or the Stock Agent shall be entitled to deduct and withhold from the consideration otherwise payable to any holder of Shares, Company Stock Options or otherwise pursuant to this Agreement such amounts as the Surviving Corporation or the Stock Agent is required to deduct and withhold with respect to the making of such payment under any provision of any tax Laws and regulations. To the extent that amounts are so withheld and paid over to the appropriate taxing authority by the Surviving Corporation or the Stock Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made.

Section 4.5Dissenting Shares.

Notwithstanding anything in this Agreement to the contrary, Shares issued and outstanding immediately prior to the Closing Date that are held by any holder who has not voted in favor of the Merger and who is entitled to demand and properly demands appraisal of such Shares pursuant to, and who complies in all respects with the ROC Company Act and the ROC Enterprise Mergers and Acquisitions Act ("Dissenting Shares") shall not be converted into the right to receive the Merger Consideration, unless and until such holder shall have failed to perfect, or shall have effectively withdrawn or lost, such holder's right to appraisal under applicable Law. Dissenting Shares shall be treated in accordance with the ROC Company Act and the ROC Enterprise Mergers and Acquisitions Act. If any such holder fails to perfect or withdraws or loses any such right to appraisal, then each such Share of such holder shall thereupon be converted into and become exchangeable only for the right to receive, as of the later of the Closing Date and the time that such right to appraisal has been irrevocably lost, withdrawn or expired, the Merger Consideration in accordance with Section 4.1(a). Immediately after the shareholders' meeting or the board meeting of the Company where the Merger is approved, as the case may be, the Company shall promptly notify Merger Sub of any demands for appraisal of any Shares, attempted withdrawals of such notices or demands and any other instruments received by the Company relating to rights to appraisal, and Merger Sub shall have the right to participate in all negotiations and proceedings with respect to such demands subject, prior to the Closing Date, to consultation with the Company. Prior to the Closing Date, the Company shall not, without the prior written consent of Merger Sub, which shall not be unreasonably withheld or delayed, make any payment with respect to, settle or offer to settle, or approve any withdrawal of any such demands.

Section 4.6Adjustment of Merger Consideration.

In the event that the Company (a) issues cash dividend, or (b) changes the number of Shares issued and outstanding as a result of a stock split, stock dividend, recapitalization, subdivision, reclassification, combination or similar transaction with respect to the outstanding Shares, and in each case the record date therefor shall be prior to the Closing Date, the Merger Consideration and any other calculations based on or relating to Shares shall be, in the case of subsection (a), reduced by the amount of cash dividend per share on a dollar-for-dollar-basis, and in the case of subsection (b), appropriately, equitably and proportionately adjusted in light of such stock split, stock dividend, recapitalization, subdivision, reclassification, combination or similar transaction. Furthermore, if

13

any change of the Company's financial or business conditions have any Material Adverse Effect before the Closing Date, the Company Board and the board of the Merger Sub are authorized to further discuss and determine the proper adjustment, if necessary, to the Merger Consideration.

16

(i)Company Common Stock. Each Share issued and outstanding immediately prior to the Effective Time (other than (A) Shares owned by Parent, Merger Sub or the Company, or by any direct or indirect wholly-owned Subsidiary of Parent, Merger Sub or the Company, in each case immediately prior to the Effective Time and (B) Dissenting Shares) shall be canceled and extinguished and automatically converted into the right to receive cash in an amount equal to the Merger Consideration, without interest thereon, upon the surrender of the certificate representing such Share in the manner provided in Section 2.8 (or in the case of a lost, stolen or destroyed certificate, upon delivery of an affidavit (and bond, if required) in the manner provided in Section 2.10).

(ii)Owned Company Common Stock. Each Share owned by Parent, Merger Sub or the Company, or by any direct or indirect wholly-owned Subsidiary of Parent, Merger Sub or the Company, in each case immediately prior to the Effective Time shall be cancelled and extinguished without any conversion thereof or consideration paid therefor.

(b)Adjustment to Merger Consideration. The Merger Consideration shall be adjusted appropriately to reflect the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Shares), cash dividends, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to Shares occurring on or after the date hereof and prior to the Effective Time.

(c)Statutory Rights of Appraisal.

(i)Notwithstanding anything to the contrary set forth in this Agreement, Shares that are issued and outstanding immediately prior to the Effective Time and held by holders of Shares that have made written demand upon the Company for the purchase of such Shares and payment to the holders in cash of the “fair market value” of such Shares (the “Demand Notice”) and perfected their rights in accordance with Chapter 13 of the CGCL (collectively, “Dissenting Shares”) shall not be converted into, or represent the right to receive, the Merger Consideration pursuant to this Section 2.7. Such holders of Shares shall be entitled to only such rights as are granted by Chapter 13 of the CGCL, except that all such holders that have failed to perfect or who shall have effectively waived, withdrawn or lost their rights under Chapter 13 of the CGCL shall thereupon be deemed to have been converted into, and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration, without any interest thereon, upon surrender of the certificate or certificates that formerly evidenced such Shares in the manner provided in Section 2.8.

17

(ii)The Company shall give Parent (A) prompt notice of any Demand Notice received by the Company, withdrawals thereof, and any other instruments served pursuant to Chapter 13 of the CGCL and received by the Company in respect of Dissenting Shares and (B) the opportunity to direct all negotiations and proceedings with respect to the exercise of any rights of the holder of Dissenting Shares under Chapter 13 of the CGCL.

(d)Company Options. At the Effective Time, each Company Option then outstanding under any of the Company Option Plans shall be treated in accordance with the provisions of Section 6.11.

2.8Exchange of Certificates. 

(a)Payment Agent. Prior to the Effective Time, Parent shall select a bank or trust company reasonably acceptable to the Company to act as the payment agent for the Merger (the “Payment Agent”).

(b)Exchange Fund. Promptly following the Effective Time, Parent shall deposit (or cause to be deposited) with the Payment Agent, for payment to the holders of Shares pursuant to the provisions of this Article II, an amount of cash equal to the product obtained by multiplying (x) the Merger Consideration and (y) the aggregate number of Shares issued and outstanding immediately prior to the Effective Time (excluding Shares then owned by Parent, Merger Sub, the Company, or any direct or indirect wholly-owned Subsidiary of Parent, Merger Sub or the Company immediately prior to the Effective Time) (such cash amount being referred to herein as the “Exchange Fund”).

(c)Payment Procedures. Promptly following the Effective Time, Parent and Merger Sub shall cause the Payment Agent to mail to each holder of record (as of immediately prior to the Effective Time) of a certificate or certificates (the “Certificates”), which immediately prior to the Effective Time represented outstanding Shares (other than Dissenting Shares) a letter of transmittal in customary form (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Payment Agent) and instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration payable in respect thereof pursuant to the provisions of this Article II. Upon surrender of Certificates for cancellation to the Payment Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the holders of such Certificates shall be entitled to receive in exchange therefor the Merger Consideration payable in respect thereof pursuant to the provisions of this Article II, and the Certificates so surrendered shall forthwith be canceled. The Payment Agent shall accept such Certificates upon compliance with such reasonable terms and conditions as the Payment Agent may impose to effect an orderly exchange thereof in

18

accordance with normal exchange practices. No interest shall be paid or accrued for the benefit of holders of the Certificates on the Merger Consideration payable upon the surrender of such Certificates pursuant to this Section 2.8. Until so surrendered, outstanding Certificates shall be deemed from and after the Effective Time, to evidence only the right to receive the Merger Consideration payable in respect thereof pursuant to the provisions of this Article II.

(d)Transfers of Ownership. In the event that a transfer of ownership of Shares is not registered in the stock transfer books or ledger of the Company, or if Merger Consideration is to be paid in a name other than that in which the Certificates surrendered in exchange therefor are registered in the stock transfer books or ledger of the Company, the Merger Consideration may be paid to a Person other than the Person in whose name the Certificate so surrendered is registered in the stock transfer books or ledger of the Company only if such Certificate is properly endorsed and otherwise in proper form for surrender and transfer and the Person requesting such payment has paid to Parent (or any agent designated by Parent) any transfer or other Taxes required by reason of the payment of Merger Consideration to a Person other than the registered holder of such Certificate, or established to the satisfaction of Parent (or any agent designated by Parent) that such transfer or other Taxes have been paid or are otherwise not payable.

(e)Required Withholding. Each of the Payment Agent, Parent and the Surviving Corporation shall be entitled to deduct and withhold from any amounts payable pursuant to this Agreement such amounts as may be required to be deducted or withheld therefrom under U.S. federal or state, local or non-U.S. Law. To the extent that such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

(f)No Liability. Notwithstanding anything to the contrary set forth in this Agreement, none of the Payment Agent, Parent, the Surviving Corporation or any other party hereto shall be liable to a holder of Shares for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(g)Unclaimed Property. Subject to applicable unclaimed property Laws, Parent will cause the Payment Agent to initiate unclaimed property reporting services for unclaimed Shares and related cash distributions that may be deemed abandoned or otherwise subject to applicable unclaimed property Law. Such services may include preparation of unclaimed property reports, delivery of abandoned property to various states, completion of required due diligence notifications, responses to inquiries from owners, and such other services as may reasonably be necessary to comply with applicable unclaimed property Laws.

2.9No Further Ownership Rights in Company Common Stock.  From and after the Effective Time, all Shares shall no longer be outstanding and shall automatically be cancelled, retired and cease to exist, and each holder of a Certificate theretofore representing any Shares (other than Dissenting Shares) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration payable therefor upon the surrender thereof in accordance with the provisions of Section 2.8. The Merger Consideration paid in

19

accordance with the terms of this Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of the Company Common Stock. From and after the Effective Time, there shall be no further registration of transfers on the records of the Surviving Corporation of Shares that were issued and outstanding immediately prior to the Effective Time, other than transfers to reflect, in accordance with customary settlement procedures, trades effected prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article II.

2.10Lost, Stolen or Destroyed Certificates.  In the event that any Certificates shall have been lost, stolen or destroyed, the Payment Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, the Merger Consideration payable in respect thereof pursuant to Section 2.7; provided, however, that Parent or the Payment Agent may, in their discretion and as a condition precedent to the payment of such Merger Consideration, require the owners of such lost, stolen or destroyed Certificates to deliver a bond in such sum as they may reasonably direct as indemnity against any claim that may be made against Parent, the Surviving Corporation or the Payment Agent with respect to the Certificates alleged to have been lost, stolen or destroyed.

2.11Taking of Necessary Action; Further Action.  If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of the Company and Merger Sub, the directors and officers of the Surviving Corporation shall take all such lawful and necessary action on behalf of the Company and Merger Sub.

Each of the Company and its Subsidiaries is duly qualified to do business and is in good standing in each jurisdiction where the character of its properties owned or leased or the nature of its activities make such qualification necessary (to the extent the “good standing” concept is applicable in the case of any jurisdiction outside the United States), except where the failure to be so qualified or in good standing would not have, individually or in the aggregate, a Company Material Adverse Effect. The Company has delivered or made available to Parent complete and correct copies of (a) the certificates of incorporation and bylaws or other constituent documents, as amended to date, of the Company and its Subsidiaries and (b) the minutes (or, in the case of draft minutes, the most recent drafts thereof) of all meetings of the shareholders, the Company Board and each committee of the Company Board since January 1, 2009.

3.2Subsidiaries. 

(a)Section 3.2(a) of the Company Disclosure Letter contains a complete and accurate list of the name, jurisdiction of organization and function (i.e., sales, manufacturing, administration, etc.) of each Subsidiary of the Company. Except for the Company’s Subsidiaries, the Company does not own, directly or indirectly, any capital stock of, or other equity or voting interest in, any Person.

(b)All of the outstanding capital stock of, or other equity or voting interest in, each Subsidiary of the Company (i) have been duly authorized, validly issued and are fully paid and nonassessable and (ii) are owned, directly or indirectly, by the Company, free and clear of all Liens and free of any other restriction (including any restriction on the right to vote, sell or otherwise dispose of such capital stock or other equity or voting interest) that would prevent the operation by the Surviving Corporation of such Subsidiary’s business as presently conducted.

(c)There are no outstanding (i) securities of the Company or any of its Subsidiaries convertible into or exchangeable for shares of capital stock of, or other equity or voting interest in, any Subsidiary of the Company, (ii) options, warrants, rights or other commitments or agreements to acquire from the Company or any of its Subsidiaries, or that obligate the Company or any of its Subsidiaries to issue, any capital stock of, or other equity or voting interest in, or any securities convertible into or exchangeable for shares of capital stock of, or other equity or voting interest in, any Subsidiary of the Company, (iii) obligations of the Company to grant, extend or enter into any subscription, warrant, right, convertible or exchangeable security or other similar agreement or commitment relating to any capital stock of, or other equity or voting interest (including any voting debt) in, any Subsidiary of the Company (the items in clauses (i), (ii) and (iii), together with the capital stock of the Subsidiaries of the Company, being referred to collectively as “Subsidiary Securities”) or (iv) other obligations by the Company or any of its Subsidiaries to make any payments based

21

on the price or value of any Subsidiary Securities. There are no Contracts of any kind which obligate the Company or any of its Subsidiaries to repurchase, redeem or otherwise acquire any outstanding Subsidiary Securities.

(b)At all times during the period commencing with the execution and delivery of this Agreement and continuing until the earlier to occur of (x) the termination of this Agreement pursuant to Article VIII and (y) the Effective Time, the Company and its Subsidiaries shall not, and shall use their reasonable best efforts to cause any of their respective directors, officers or other employees, controlled affiliates, or any investment banker, attorney or other advisors or representatives retained by any of them (collectively, the “Company Representatives”) not to (and shall not authorize or permit any of them to), directly or indirectly, (i) solicit, initiate, knowingly encourage or facilitate the making, submission or announcement of, an Acquisition Proposal, (ii) furnish to any Person (other than Parent, Merger Sub or any designees of Parent or Merger Sub) any non-public information relating to the Company or any of its Subsidiaries that the Company believes or should reasonably expect could be used for the purposes of making, submitting or announcing an Acquisition Proposal, or afford access to the business, properties, assets, books or records of the Company or any of its Subsidiaries to any Person (other than Parent, Merger Sub or any designees of Parent or Merger Sub) that the Company believes or should reasonably expect could be used for the purposes of making, submitting or announcing an Acquisition Proposal, or take any other action intended to assist or facilitate any inquiries or the making of any proposal that constitutes or would be reasonably expected to lead to an Acquisition Proposal, (iii) participate or engage in discussions or negotiations with any Person with respect to an Acquisition Proposal, (iv) approve, endorse or recommend an Acquisition Proposal, (v) execute or enter into any letter of intent, memorandum of understanding or Contract contemplating or otherwise relating to an Acquisition Transaction or (vi) terminate, amend, modify, waive or fail to enforce any rights under any “standstill” or other similar agreement between the Company or any of its Subsidiaries and any Person (other than Parent); provided, however, that notwithstanding the foregoing, prior to obtaining the Requisite Shareholder Approval, the Company Board may, directly or indirectly through Representatives, advisors, agents or other intermediaries, subject to the Company’s compliance with the provisions of this Section 6.1, with respect to any Person that has made (and not withdrawn) a bona fide, written Acquisition Proposal that did not result from a breach of this Section 6.1, and that the Company Board reasonably concludes in good faith (after consultation with a financial advisor of nationally recognized standing and its outside legal counsel) constitutes or is reasonably likely to lead to a Superior Proposal, (A) engage or participate in discussions or negotiations with such Person and/or (B) furnish to such Person any non-public information relating to the

56

Company or any of its Subsidiaries pursuant to a confidentiality agreement, the terms of which are no less favorable to the Company than those contained in the Confidentiality Agreement, provided that in the case of any action taken pursuant to the foregoing clauses (A) or (B), (1) none of the Company or any of its Subsidiaries shall have breached or violated (or be deemed, pursuant to the terms of this Section 6.1, to have breached or violated) the terms of this Section 6.1 in any material respect, (2) the Company Board determines in good faith (after consultation with outside legal counsel) that the failure to take such action would reasonably be expected to result in a breach of its fiduciary duties to the shareholders of the Company under California Law, (3) solely with respect to the initial contact with such Person, at least forty-eight (48) hours prior to engaging or participating in any such discussions or negotiations with, or furnishing any non-public information to, such Person, the Company gives Parent written notice of the identity of such Person and all of the terms and conditions of such Acquisition Proposal (and if such Acquisition Proposal is in written form, the Company shall give Parent a copy thereof) and of the Company’s intention to engage or participate in discussions or negotiations with, or furnish non-public information to, such Person and (4) contemporaneously with furnishing any non-public information to such Person, the Company furnishes such non-public information to Parent (to the extent such information has not been previously furnished by the Company to Parent).

(c)Without limiting the generality of the foregoing, Parent, Merger Sub and the Company acknowledge and hereby agree that any violation of the restrictions set forth in this Section 6.1 by any Company Representative shall be deemed to be a breach of this Section 6.1 by the Company. The Company shall not enter into any letter of intent, memorandum of understanding or Contract (other than a confidentiality agreement as permitted by Section 6.1(b)) contemplating or otherwise relating to an Acquisition Proposal unless and until this Agreement is terminated pursuant to Article VIII and the Company has paid all amounts due to Parent pursuant to Section 8.3, if any.

(d)In addition to the obligations of the Company set forth in Section 6.1(b), the Company shall promptly, and in all cases within twenty four (24) hours of its receipt, advise Parent orally and in writing of (i) any Acquisition Proposal, (ii) any request for information that the Company believes or should reasonably expect could be used for the purposes of making, submitting or announcing an Acquisition Proposal or (iii) any inquiry that contributes or would reasonably be expected to lead to, any Acquisition Proposal, the terms and conditions of such Acquisition Proposal, request or inquiry, and the identity of the Person or group making any such Acquisition Proposal, request or inquiry.

(e)The Company shall keep Parent promptly (and in all cases within twenty-four (24) hours) informed of the status, details, terms and conditions (including all amendments or proposed amendments) of any such Acquisition Proposal, request or inquiry, and shall promptly (and in all cases within twenty-four (24) hours) provide Parent with copies of all documents and written or electronic communications comprising part of any such Acquisition Proposal exchanged between the Company or any Company Representative, on the one hand, and the Person from which such Acquisition Proposal was received (or such Person’s representatives), on the other hand. In addition to the foregoing, the Company shall

57

provide Parent with at least seventy-two (72) hours (or such shorter period as provided to the members of the Company Board) prior written notice of a meeting of the Company Board at which the Company Board is reasonably expected to consider an Acquisition Proposal, an inquiry relating to a potential Acquisition Proposal, or a request to provide nonpublic information to any Person.

6.2Company Board Recommendation. 

(a)Subject to the terms of Section 6.2(b), the Company Board shall (i) recommend that the holders of Shares approve this Agreement in accordance with the applicable provisions of California Law (the “Company Board Recommendation”) and (ii) include the Company Board Recommendation in the Proxy Statement.

(b)Subject to the terms of this Section 6.2(b), neither the Company Board nor any committee thereof shall withhold, withdraw, amend or modify in a manner adverse to Parent, or publicly propose to withhold, withdraw, amend or modify in a manner adverse to Parent, the Company Board Recommendation (a “Company Board Recommendation Change”); provided, however, that notwithstanding the foregoing, the Company Board may effect a Company Board Recommendation Change at any time prior to obtaining the Requisite Shareholder Approval, if and only if:

(i)(A) the Company Board has received a bona fide, written Acquisition Proposal that did not result from a breach of Section 6.1 that constitutes a Superior Proposal, (B) neither the Company nor any of its Subsidiaries shall have breached or violated (or be deemed, pursuant to the terms hereof, to have breached or violated) the provisions of Section 6.1 in any material respect, (C) the Company Board determines in good faith (after consultation with outside legal counsel and after considering in good faith any counter-offer or proposal made by Parent pursuant to clause (E) below), that, in light of such Superior Proposal, the failure of the Company Board to effect a Company Board Recommendation Change would reasonably be expected to result in a breach of its fiduciary duties to shareholders of the Company under California Law, (D) prior to effecting such Company Board Recommendation Change, the Company Board shall have given Parent at least five (5) Business Days’ notice thereof (which notice shall include the most current version of such definitive agreement and, to the extent not included therein, the material terms and conditions of such Superior Proposal and the identity of the Person making such Superior Proposal) and the opportunity to meet with the Company Board and its outside legal counsel during such five (5) Business Day period, all with the purpose and intent of enabling Parent and the Company to discuss in good faith a modification of the terms and conditions of this Agreement so as to obviate the need for the Company Board to effect a Company Board Recommendation Change, and (E) Parent shall not have made, within five (5) Business Days after receipt of the Company’s written notice of its intention to effect a Company Board Recommendation Change, a counter-offer or proposal that the Company Board reasonably determines in good faith, after consultation with a financial advisor of nationally recognized standing and its outside legal counsel, is at least as favorable to shareholders of the Company as such Superior Proposal (it being understood that any change to the financial terms or any other material term

58

or condition of such Superior Proposal shall require a new notice pursuant to clause (D) above and a new five (5) Business Day period pursuant to this clause (D)); or

(ii)(A) an “Intervening Event” as defined below shall have occurred and be continuing, (B) the Company Board determines in good faith (after consultation with outside legal counsel and after considering in good faith any counter-offer or proposal made by Parent pursuant to clause (D) below), that, in light of such Intervening Event, the failure of the Company Board to effect a Company Board Recommendation Change would reasonably be expected to result in a breach of its fiduciary duties to shareholders of the Company under California Law, (C) prior to effecting such Company Board Recommendation Change, the Company Board shall have given Parent at least five (5) Business Days’ notice thereof (which notice shall include a written explanation of the Company Board’s basis and rationale for proposing to effect such Company Board Recommendation Change) and the opportunity to meet with the Company Board and its outside legal counsel during such five (5) Business Day period, all with the purpose and intent of enabling Parent and the Company to discuss in good faith a modification of the terms and conditions of this Agreement so as to obviate the need for the Company Board to effect a Company Board Recommendation Change, and (D) Parent shall not have made, within five (5) Business Days after receipt of the Company’s written notice of its intention to effect a Company Board Recommendation Change, a counter-offer or proposal that the Company Board reasonably determines in good faith, after consultation with a financial advisor of nationally recognized standing and its outside legal counsel, would obviate the need for the Company Board to effect such Company Board Recommendation Change. For these purposes, an “Intervening Event” means a material fact, event, change, development or set of circumstances occurring or existing after the date of this Agreement with respect to the business, operations, financial condition or results of operations of the Company or any of its Subsidiaries (and not relating in any way to (x) an Acquisition Proposal or (y) any fluctuation in the market price or trading volume of the Shares, in and of itself) that was not known to the Company Board nor reasonably foreseeable by the Company Board as of or prior to the date of this Agreement.

(c)Nothing in this Agreement shall prohibit the Company Board from taking and disclosing to shareholders of the Company a position contemplated by Rule 14e-2(a) under the Exchange Act that the Company Board determines in good faith (after consultation with outside legal counsel) that such disclosure is likely required in order to comply with its fiduciary duties to shareholders of the Company under California Law; provided that any statement(s) made by the Company Board pursuant to this sentence shall be subject to the terms and conditions of this Agreement, including the provisions of Article VIII (it being acknowledged and agreed that any such disclosure, other than a “stop, look and listen” communication of the type contemplated by Section 14d-9(f) of the Exchange Act or any other disclosure made pursuant to Section 6.2(c) that is limited to describing the existence and terms of any Acquisition Proposal, shall be deemed to be in a Company Board Recommendation Change unless the Company Board expressly publicly reaffirms the Company Board Recommendation in such communication).

59

(d)The Company shall not take any action to exempt any Person (other than Parent, Merger Sub and their respective Affiliates) from the provisions on “control share acquisitions” contained in any Takeover Law or otherwise cause such restrictions not to apply. To the extent permitted thereunder, the Company shall promptly take all steps necessary to terminate any waiver or other exemption that may have been heretofore granted to any such Person or any Acquisition Proposal under any such provision.

6.3Company Shareholders’ Meeting.  The Company shall establish a record date for, call, give notice of, convene and hold a meeting of the shareholders of the Company (the “Company Shareholders’ Meeting”) as promptly as practicable following the date of this Agreement (and in no event later than 30 days after the commencement of the mailing of the Proxy Statement to the Company’s shareholders) for the purpose of voting upon the adoption of this Agreement in accordance with California Law. Notwithstanding the foregoing, (i) if there are insufficient shares of the Company Common Stock necessary to conduct business at the Company Shareholders’ Meeting, the Company may extend the date of the Company Shareholders’ Meeting to the extent (and only to the extent) necessary in order to conduct business at the Company Shareholders’ Meeting, (ii) the Company may delay the Company Shareholders’ Meeting to the extent (and only to the extent) the Company reasonably determines that such delay is required by applicable Law to comply with comments made by the SEC with respect to the Proxy Statement, and (iii) with the prior written consent of Parent or if Parent requests an extension, the Company shall delay the Company Shareholders’ Meeting for a period not to exceed ten (10) Business Days. The Company shall solicit from shareholders of the Company proxies in favor of the adoption of this Agreement in accordance with California Law, and shall use its reasonable best efforts to secure the Requisite Shareholder Approval at the Company Shareholders’ Meeting. Unless this Agreement is earlier terminated pursuant to Article VIII, the Company shall establish a record date for, call, give notice of, convene and hold the Company Shareholders’ Meeting for the purpose of voting upon the adoption of this Agreement in accordance with California Law, whether or not the Company Board at any time subsequent to the date hereof shall have effected a Company Board Recommendation Change or otherwise shall determine that this Agreement is no longer advisable or recommends that shareholders of the Company reject it. Unless this Agreement has been terminated pursuant to Section 8.1(d)(ii), the Company’s obligation to establish a record date for, call, give notice of, convene and hold the Company Shareholders’ Meeting pursuant to this Section 6.3 shall not be limited to, or otherwise affected by, the commencement, disclosure, announcement or submission to the Company of any Acquisition Proposal.

6.4Proxy Statement. 

(a)As soon as practicable following the date of this Agreement, the Company shall prepare and no later than the tenth (10^th) Business Day following the public announcement of the execution and delivery of this Agreement, the Company shall file with the SEC the Proxy Statement for use in connection with the solicitation of proxies from shareholders of the Company in connection with the Merger and the Company Shareholders’ Meeting. The Company and Parent, as the case may be, shall furnish all information

60

concerning the Company or Parent as the other party hereto may reasonably request in connection with the preparation and filing with the SEC of the Proxy Statement. Subject to all applicable Laws, the Company shall use its reasonable best efforts to cause the Proxy Statement to be disseminated to shareholders of the Company as promptly as practicable following the filing thereof with the SEC. Notwithstanding anything to the contrary set forth in this Agreement, the Company shall file with the SEC the definitive Proxy Statement, and shall cause the mailing of the definitive Proxy Statement to the shareholders of the Company, on or prior to the second (2^nd) Business Day immediately following the later of (i) receipt and resolution of SEC comments thereon, or (ii) the expiration of the 10-day waiting period provided in Rule 14a-6(a) promulgated under the Exchange Act. No filing of, or amendment or supplement to, or correspondence with the SEC or its staff with respect to the Proxy Statement shall be made by the Company without providing Parent a reasonable opportunity to review and comment thereon, including in such filings, amendments, supplements and correspondence all comments reasonably proposed by Parent and receiving the approval of Parent (which approval shall not be unreasonably withheld or delayed). The Company shall advise Parent, promptly after it receives notice thereof, of any request by the SEC or its staff for an amendment or revisions to the Proxy Statement, or comments thereon and responses thereto, or requests by the SEC or its staff for additional information in connection therewith, and shall provide Parent with copies of all correspondence between the Company or any of its advisors or representatives, on the one hand, and the SEC, or its staff or any other government officials, on the other hand, with respect to the Proxy Statement or other filing with the SEC. If the Company or its outside legal counsel intends to initiate a telephone conference or meet with the SEC and its staff related to the Proxy Statement, this Agreement or the Merger, the Company shall so inform the Parent and solicit input on the items planned to be discussed during such telephone conference or meeting. If at any time prior to the Company Shareholders’ Meeting, any information relating to the Company or Parent, or any of their respective directors, officers or Affiliates, should be discovered by the Company or Parent which should be set forth in an amendment or supplement to the Proxy Statement so that the Proxy Statement does not include any untrue statement of a material fact or omits to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party which discovers such information shall promptly notify the other party or parties hereto, as the case may be, and an appropriate amendment or supplement to the Proxy Statement describing such information shall be promptly prepared and filed with the SEC and, to the extent required by applicable Law, disseminated to the shareholders of the Company. The Company shall cause the Proxy Statement to comply as to form and substance in all material respects with the applicable requirements of the Exchange Act, California Law and the rules of the Nasdaq.

(b)Unless this Agreement is earlier terminated pursuant to Article VIII, subject to the terms of Section 6.2(b), the Company shall include in the Proxy Statement the Company Board Recommendation.

61

6.5Reasonable Best Efforts to Complete. 

(a)Upon the terms and subject to the conditions set forth in this Agreement, each of Parent, Merger Sub and the Company shall use their reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other party or parties hereto in doing, all things reasonably necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated by this Agreement (including the Merger), including using reasonable best efforts to: (i) cause the conditions to the Merger set forth in Article VII hereof to be satisfied or fulfilled; (ii) obtain all necessary or appropriate consents, waivers and approvals under any Contracts to which the Company or any of its Subsidiaries is a party in connection with this Agreement and the consummation of the transactions contemplated hereby (including the Merger) so as to maintain and preserve the benefits under such Contracts following the consummation of the transactions contemplated hereby (including the Merger); (iii) obtain all necessary actions or non-actions, waivers, consents, approvals, Orders and authorizations from Governmental Entities, the expiration or termination of any applicable waiting periods, making all necessary registrations, declarations and filings (including registrations, declarations and filings with Governmental Entities, if any) and (iv) execute or deliver any additional instruments reasonably necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, this Agreement.

(b)Without limiting the generality of the foregoing provisions of Section 6.5(a), as soon as may be reasonably practicable following the execution and delivery of this Agreement, each of Parent and the Company shall file with the FTC and the Antitrust Division of the DOJ a Notification and Report Form relating to this Agreement and the transactions contemplated hereby (including the Merger) as required by the HSR Act, as well as comparable pre-merger notification filings, forms and submissions with any foreign Governmental Entity that may be required by the merger notification or control Laws and regulations of any applicable foreign jurisdiction or be deemed desirable by Parent, in each case as Parent may deem necessary and/or appropriate. Each of Parent and the Company shall promptly (i) cooperate and coordinate with the other in the making of such filings, (ii) supply the other with any information that may be required in order to effectuate such filings, and (iii) supply any additional information that reasonably may be required or requested by the FTC, the DOJ or the competition or merger control authorities of any other jurisdiction and that Parent reasonably deems necessary and/or appropriate. Parent and the Company shall share equally all fees and expenses incurred in connection with filings made in connection with this Section 6.5(b). Each party hereto shall promptly inform the other party or parties hereto, as the case may be, of any communication from any Governmental Entity regarding any of the transactions contemplated by this Agreement (including the Merger). If any party hereto or Affiliate thereof receives a request for additional information or documentary material from any such Governmental Entity with respect to the transactions contemplated by this Agreement (including the Merger), then such party shall use reasonable best efforts to make, or cause to be made, as soon as reasonably practicable and after consultation with the other party, an appropriate response in compliance with such request.

62

(c)Without limiting the generality of the foregoing provisions of Section 6.5(a), in the event that any Takeover Law is or becomes applicable to this Agreement or any of the transactions contemplated by this Agreement (including the Merger), the Company, at the direction of the Company Board, shall use reasonable best efforts to ensure that the transactions contemplated by this Agreement (including the Merger) may be consummated as promptly as practicable on the terms and subject to the conditions set forth in this Agreement, and otherwise to minimize the effect of such statute or regulation on this Agreement and the transactions contemplated hereby (including the Merger).

(d)Notwithstanding anything in this Agreement to the contrary, it is expressly understood and agreed that: (i) neither Parent nor Merger Sub shall have any obligation to litigate or contest any administrative or judicial action or proceeding or any decree, judgment, injunction or other order, whether temporary, preliminary or permanent; and (ii) neither Parent nor Merger Sub shall be under any obligation to make proposals, execute or carry out agreements, enter into consent decrees or submit to orders providing for (A) the sale, divestiture, license or other disposition or holding separate (through the establishment of a trust or otherwise) of any assets or categories of assets of Parent or any of its Subsidiaries or the Company or any of its Subsidiaries, (B) the imposition of any limitation or regulation on the ability of Parent or any of its Subsidiaries to freely conduct their business or own such assets, or (C) the holding separate of the shares of Company Common Stock or any limitation or regulation on the ability of Parent or any of its Subsidiaries to exercise full rights of ownership of the shares of Company Common Stock, other than, in the case of clauses (A), (B) and (C) above, for any such sale, divestiture, license, disposition, holding separate, limitation or regulation that, individually or in the aggregate, would be immaterial to Parent and/or the Company and their respective Subsidiaries, taken as a whole (with materiality, for purposes of this provision, being measured in relation to the Company and its Subsidiaries taken as a whole) (any of the foregoing, an “Antitrust Restraint”).

6.6Access. 

(a)At all times during the period commencing with the execution and delivery of this Agreement and continuing until the earlier to occur of (x) the termination of this Agreement pursuant to Article VIII and (y) the Effective Time, the Company shall afford Parent and its accountants, legal counsel and other representatives full and complete access during normal business hours, upon reasonable notice, to the assets (including the Company IP, design processes and source code), properties (including the right to conduct an environmental site assessment and audit of the properties), books and records and personnel of the Company to enable Parent to obtain all information concerning the business, including the status of product development efforts, properties, results of operations and personnel of the Company, as Parent may request; provided, however, that no information or knowledge obtained by Parent in any investigation conducted pursuant to this Section 6.6 shall affect or be deemed to modify any representation or warranty of the Company set forth herein or the conditions to the obligations of Parent and Merger Sub to consummate the transactions contemplated hereby, including the Merger, or the remedies available to the parties hereunder; and provided further, that the terms and conditions of the Confidentiality Agreement (as

63

amended pursuant to Section 6.9) shall apply to any information provided to Parent pursuant to this Section 6.6.

(b)In particular, but without limitation, from and after the date of this Agreement, Parent and its agents, contractors and representatives shall have the right and privilege of entering upon all properties leased or occupied by the Company or any of its Subsidiaries and of reviewing the Company’s books and records regarding such properties from time to time as needed to make any inspections, evaluations, surveys or tests which Parent may deem necessary or appropriate. Parent’s exercise of its right to inspect such properties, or Parent’s election not to inspect any property, shall in no way be interpreted as a waiver of any of Parent’s rights or remedies contained in this Agreement, including, without limitation, Parent’s right to rely upon the Company’s representations and warranties in this Agreement.

(c)Parent and the Company agree to mutually cooperate in testing the Company’s IT systems for compatibility and interoperability with Parent’s IT systems and in other like matters as reasonably requested by Parent prior to Closing. In particular, but without limitation, from and after the date of the satisfaction of the condition set forth in Section 7.1(b), the Company shall provide to Parent the information described on Schedule 6.6(c) for purposes of allowing Parent to test its internal business systems ability to accept and process Company data.

6.7Notification. 

(a)At all times during the period commencing with the execution and delivery of this Agreement and continuing until the earlier to occur of (x) the termination of this Agreement pursuant to Article VIII and (y) the Effective Time, the Company shall give prompt notice to Parent upon becoming aware that any representation or warranty made by it in this Agreement has become untrue or inaccurate in any material respect if such would give rise to the ability of the Parent not to close under Section 7.2(a), or of any failure of the Company to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement; provided, however, that no such notification shall affect or be deemed to modify any representation or warranty of the Company set forth herein or the conditions to the obligations of Parent and Merger Sub to consummate the transactions contemplated hereby, including the Merger, or the remedies available to the parties hereunder; and provided further, that the terms and conditions of the Confidentiality Agreement (as amended pursuant to Section 6.9) shall apply to any information provided to Parent pursuant to this Section 6.7(a).

(b)At all times during the period commencing with the execution and delivery of this Agreement and continuing until the earlier to occur of (x) the termination of this Agreement pursuant to Article VIII and (y) the Effective Time, the Company shall give prompt notice to Parent of any notice or other communication received by the Company or any of its Subsidiaries from any third party, subsequent to the date of this Agreement and prior to the Effective Time, alleging that the consent of such third party is or may be required in connection with the transactions contemplated by this Agreement (including the Merger);

64

provided, however, that no such notification shall affect or be deemed to modify any representation or warranty of the Company set forth herein or the conditions to the obligations of Parent and Merger Sub to consummate the transactions contemplated hereby, including the Merger, or the remedies available to the parties hereunder; and provided further, that the terms and conditions of the Confidentiality Agreement (as amended pursuant to Section 6.9) shall apply to any information provided to Parent pursuant to this Section 6.7(b).

(c)At all times during the period commencing with the execution and delivery of this Agreement and continuing until the earlier to occur of (x) the termination of this Agreement pursuant to Article VIII and (y) the Effective Time, Parent shall give prompt notice to the Company upon becoming aware that any representation or warranty made by it or Merger Sub in this Agreement has become untrue or inaccurate in any material respect if such would give rise to the ability of the Company not to close under Section 7.3(a), or of any failure of Parent or Merger Sub to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement; provided, however, that no such notification shall affect or be deemed to modify any representation or warranty of the Company set forth herein or the conditions to the obligations of Parent and Merger Sub to consummate the transactions contemplated hereby, including the Merger, or the remedies available to the parties hereunder and provided further, that the terms and conditions of the Confidentiality Agreement (as amended pursuant to Section 6.9) shall apply to any information provided to the Company pursuant to this Section 6.7(c).

6.8Certain Litigation.  The Company shall promptly advise Parent orally and in writing of any litigation commenced after the date hereof against the Company or any of its directors by any shareholder of the Company (on their own behalf or on behalf of the Company) relating to this Agreement or the transactions contemplated hereby (including the Merger) and shall keep Parent reasonably informed regarding any such litigation. The Company shall give Parent the opportunity to consult with the Company regarding the defense or settlement of any such shareholder litigation and shall consider Parent’s views with respect to such shareholder litigation and shall not settle any such shareholder litigation without the prior written consent of Parent.

6.9Confidentiality.  Parent, Merger Sub and the Company hereby acknowledge that Parent and the Company have previously executed a Confidentiality Agreement, dated January 14, 2014 (the “Confidentiality Agreement”), which will continue in full force and effect in accordance with its terms; provided, however, that notwithstanding the foregoing, effective as of the execution and delivery hereof, the Confidentiality Agreement shall be deemed to be amended so as to permit Parent to take any action contemplated by this Agreement, including the making of any counter-offer or proposal contemplated by Section 6.2(b) (which deemed amendment shall survive any termination of this Agreement in accordance with its terms or otherwise).

6.10Public Disclosure.  None of the parties shall, without the prior written consent of other party or parties, as applicable, issue any press release or otherwise make any public statement with respect to this Agreement or the transactions contemplated hereby (including

65

the Merger), except as may be required by applicable Law or any listing agreement with a national securities exchange, in which case such party shall make commercially reasonable efforts to consult with the other party or parties prior to any such release or public statement. Notwithstanding the foregoing, Parent and the Company may make public statements in response to specific questions by the press, analysts or investors so long as any such statement is consistent with previous public statements permitted by this Section 6.10.

6.11Company Options. 

(a)At the Effective Time, each Company Option (or portion thereof) that is outstanding and vested as of immediately prior to the Effective Time (or vests as a result of the consummation of the transactions contemplated hereby) (each, a “Cancelled Option”) shall, by virtue of the Merger and at the direction of Parent (which is hereby given pursuant to this Agreement), be cancelled and terminated and converted into the right to receive an amount in cash, without interest, with respect to each share underlying such Cancelled Option, equal to the excess, if any, of the Merger Consideration over the per share exercise price of such Cancelled Option (such amount being hereinafter referred to as the “Option Consideration”). The holder of each Cancelled Option shall receive at the Effective Time from the Company, or as soon as practicable thereafter (but in no even later than the Company’s first full payroll after the Effective Time) from the Surviving Corporation, an amount in cash equal to the Option Consideration. If the exercise price per share of any such Cancelled Option is equal to or greater than the Merger Consideration, such Company Option shall, by direction of Parent (which is hereby given pursuant to this Agreement), be cancelled without any cash payment being made in respect thereof. The payment of Option Consideration to the holder of a Cancelled Option shall be reduced by any income or employment tax withholding required under the Code, any applicable Law, or as otherwise agreed by the parties at the time the Company Option was granted.

(b)At the Effective Time, each Company Option (or portion thereof) that is outstanding and unvested as of immediately prior to the Effective Time (and does not vest as a result of the consummation of the transactions contemplated hereby) shall be assumed by Parent (each, an “Assumed Option”). Each such Assumed Option shall be subject to substantially the same terms and conditions as applied to the related Company Option immediately prior to the Effective Time, including the vesting schedule applicable thereto, except that (A) the number of shares of Parent Common Stock subject to each Assumed Option shall be equal to the product of (x) the number of shares of Company Common Stock underlying such unvested Assumed Option as of immediately prior to the Effective Time multiplied by (y) the Exchange Ratio (with the resulting number rounded down to the nearest whole share), and (B) the per share exercise price of each Assumed Option shall be equal to the quotient determined by dividing (x) the exercise price per share at which such Assumed Option was exercisable immediately prior to the Effective Time by (y) the Exchange Ratio (with the resulting price per share rounded up to the nearest whole cent). Each Assumed Option so assumed by Parent shall qualify following the Effective Time as an incentive stock option as defined in Section 422 of the Code to the extent permitted under Section 422 of the Code and to the extent such Assumed Option qualified as an incentive stock option prior to

66

the Effective Time, and, further, that the assumption of Assumed Options pursuant to this Section 6.11(b) shall be effected in a manner that satisfies the requirements of Sections 409A and 424(a) of the Code and the Treasury Regulations promulgated thereunder, and this Section 6.11(b) will be construed consistent with this intent.

6.12Employee Matters.

(a)The Company shall terminate, effective no later than the day immediately preceding the date the Company becomes a member of the same Controlled Group of Corporations (as defined in Section 414(b) of the Code) as Parent (the “Retirement Plan Termination Date”), any and all employee retirement plans qualified under Section 401(a) of the Code (the “Retirement Plans”) maintained by the Company or any of its Subsidiaries, unless Parent provides written notice to the Company at least three (3) Business Days prior to the Effective Time that such Retirement Plans shall not be terminated. The Company shall provide Parent evidence that the Retirement Plans of the Company and its Subsidiaries have been terminated pursuant to resolutions of the Company Board or the board of directors of its Subsidiaries, as applicable. The form and substance of such resolutions shall be subject to the review and approval of Parent. The Company shall also take such other actions in furtherance of terminating any such Retirement Plans as Parent may reasonably request. As soon as practicable following the Retirement Plan Termination Date, Parent shall permit all Continuing Employees who were eligible to participate in any 401(k) plan maintained by the Company or any of its Subsidiaries immediately prior to the Retirement Plan Termination Date to participate in Parent’s 401(k) plan, and shall permit each such Continuing Employee to elect to transfer his or her account balance when distributed from any terminated 401(k) plan maintained by the Company or any of its Subsidiaries, including any outstanding participant loans from such 401(k) plans, to Parent’s 401(k) plan, except to the extent accepting such transfers would adversely affect the tax-qualified status of the Parent 401(k) plan, or as may be prohibited by Parent’s 401(k) plan.

(b)From and after the Effective Time through the date which is five (5) months after the date on which the Effective Time occurs, or such longer period as may be required by applicable Law, Parent will provide, or will cause to be provided, to all Continuing Employees who remain employed by Parent or any Subsidiary of Parent, compensation and benefits that are substantially comparable in the aggregate to the compensation and benefits provided to such Continuing Employees immediately prior to the Effective Time (excluding benefits derived from awards under any equity incentive plan). Following the Effective Time and to the extent permitted by applicable Laws, Parent shall, or shall cause any Subsidiary of Parent, including the Surviving Corporation to, recognize the prior service with the Company or its Subsidiaries of Continuing Employees in connection with all employee benefit plans, programs or policies of Parent or its Subsidiaries in which Continuing Employees first become eligible to participate following the Effective Time for purposes of eligibility and vesting and determination of level of benefits (including vacation), including applicability of minimum waiting periods for participation, (but not to the extent that such recognition would result in duplication of benefits). In these regards, for purposes of determining the annual deductible, co-pay and out-of pocket expense limitation under its health plan for Continuing Employees

67

who become eligible during the 2014 plan year, Parent will credit health plan expenses incurred by Continuing Employees during 2014 prior to the Effective Time as though they were incurred immediately after the Effective Time. Parent shall use commercially reasonable efforts to provide that no such Continuing Employee, or any of his or her eligible dependents, who are participating in the Company’s group health plan shall be excluded from Parent’s group health plan, or limited in coverage thereunder, by reason of any waiting period restriction or pre-existing condition limitation.

(c)The Company shall terminate any and all group severance, separation, deferred compensation or salary continuation plans, programs or arrangements maintained by the Company or any of its Subsidiaries, effective in each case no later than the day immediately preceding the Effective Time. The Company shall provide Parent evidence that such plans have been terminated pursuant to resolutions of the Company Board or the board of directors of its Subsidiaries, as applicable (the form and substance of which resolutions shall be subject to review and approval of Parent).

(d)Prior to the Effective Time, the Company ESPP shall be terminated. The rights of participants in the Company ESPP with respect to any offering period then underway under such Company ESPP shall be determined by treating the last business day prior to, or if preferable administratively, the last payroll date of the Company immediately prior to, the Effective Time, as the last day of such offering period and by making such other pro-rata adjustments as may be necessary to reflect the shortened offering period but otherwise treating such shortened offering period as a fully effective and completed offering period for all purposes under such Company ESPP. The Company shall provide that no additional offering period or purchase period shall commence under the Company ESPP after March 31, 2014. Prior to the Effective Time, and subject to the reasonable review and approval by Parent, the Company shall take all actions necessary give effect to the transactions contemplated by this Section 6.12(d).

(e)Nothing in this Agreement shall (x) create any third-party beneficiary rights in any employee or former employee (including any beneficiary or dependent thereof) or service provider or former service provider (including any beneficiary or dependent thereof) of the Company in any respect, or (y) constitute or be construed to constitute an amendment to any of the compensation or benefit plans maintained for or provided to employees or other persons prior to or following the Closing. Nothing in this Agreement shall constitute a limitation on the rights to amend, modify or terminate any such plans or arrangements of Parent or any of its subsidiaries.

6.13Directors’ and Officers’ Indemnification and Insurance. 

(a)For six (6) years after the Effective Time, Parent shall cause the Surviving Corporation and its Subsidiaries to, honor and fulfill in all respects the obligations (including the financial obligations) of the Company and its Subsidiaries under their respective certificates of incorporation and bylaws (and other similar organizational documents) and all indemnification agreements in effect immediately prior to the Effective Time between the Company or any of its Subsidiaries and any of their respective current or former directors and

68

officers and any person who becomes a director or officer of the Company or any of its Subsidiaries prior to the Effective Time (the “Indemnified Parties”). In addition, for a period of six (6) years following the Effective Time, Parent shall (and shall cause the Surviving Corporation and its Subsidiaries to) cause the articles of incorporation and bylaws (and other similar organizational documents) of the Surviving Corporation and its Subsidiaries to contain provisions with respect to indemnification and exculpation that are at least as favorable as the indemnification and exculpation provisions contained in the articles of incorporation and bylaws (or other similar organizational documents) of the Company and its Subsidiaries immediately prior to the Control Time, and during such six (6) year period, such provisions shall not be amended, repealed or otherwise modified in any manner that would adversely affect the rights thereunder of individuals who were covered by such provisions, except as required by Laws.

(b)For a period of six (6) years after the Effective Time, Parent and the Surviving Corporation shall maintain in effect the Company’s current directors’ and officers’ liability insurance (“D&O Insurance”) in respect of acts or omissions occurring at or prior to the Effective Time, covering each person covered by the D&O Insurance immediately prior to the Effective Time, on terms with respect to the coverage and amounts no less favorable, in the aggregate, than those of the D&O Insurance in effect on the date of this Agreement; provided, however, that the Surviving Corporation may, at its option, substitute therefor policies of Parent, the Surviving Corporation or any of their respective Subsidiaries containing terms with respect to coverage and amounts no less favorable, in the aggregate, to such persons than the D&O Insurance, provided further, however, that in satisfying its obligations under this Section 6.13(b) Parent and the Surviving Corporation shall not be obligated to pay annual premiums in excess of two hundred percent (200%) of the amount paid by the Company for coverage for its last full fiscal year (such two hundred percent (200%) amount, the “Maximum Annual Premium”) (which premiums the Company represents and warrants to be as set forth in Section 6.13 of the Company Disclosure Letter), provided that that if the annual premiums of such insurance coverage exceed such amount, Parent and the Surviving Corporation shall be obligated to obtain a policy with the greatest coverage available for a cost not exceeding the Maximum Annual Premium. Prior to the Effective Time, notwithstanding anything to the contrary set forth in this Agreement, the Company may purchase a six-year “tail” prepaid policy (the “Tail Policy”) on the D&O Insurance on terms and conditions no less favorable, in the aggregate, than the D&O Insurance and for an amount not to exceed three hundred fifty percent (350%) of the amount paid by the Company for coverage for its last full fiscal year. In the event that the Company does not purchase the Tail Policy, Parent may purchase a Tail Policy on the D&O Insurance on terms and conditions no less favorable, in the aggregate, than the D&O Insurance. In the event that either the Company or Parent shall purchase such a Tail Policy prior to the Effective Time, Parent and the Surviving Corporation shall maintain such Tail Policy in full force and effect and continue to honor their respective obligations thereunder, in lieu of all other obligations of Parent and the Surviving Corporation under the first sentence of this Section 6.13(b) for so long as such Tail Policy shall be maintained in full force and effect.

69

(c)If Parent or the Surviving Corporation or any of its successors or assigns shall (i) consolidate with or merge into any other entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfer all or substantially all of its properties and assets to any entity, then, and in each such case, proper provision shall be made so that the successors and assigns of such surviving corporation shall expressly assume all of the obligations of Parent and the Surviving Corporation set forth in this Section 6.13 and have at least substantially equal financial ability as the Company (immediately prior to such transaction) to satisfy the obligations of the parties pursuant to this Section 6.13 prior to such merger, consolidation or transfer becoming effective.

(d)The obligations under this Section 6.13 shall not be terminated, amended or otherwise modified in such a manner as to adversely affect any Indemnified Party (or any other person who is a beneficiary under the Tail Policy referred to in Section 6.13(b) (and their heirs and representatives)) without the prior written consent of such affected Indemnified Party or other person who is a beneficiary under the Tail Policy referred to in Section 6.13(b) (and their heirs and representatives). Each of the Indemnified Parties or other persons who are beneficiaries under the D&O Insurance or the Tail Policy referred to in Section 6.13(b) (and their heirs and representatives) are intended to be third party beneficiaries of this Section 6.13, with full rights of enforcement as if a party thereto. The rights of the Indemnified Parties (and other persons who are beneficiaries under the Tail Policy referred to in Section 6.13(b) (and their heirs and representatives)) under this Section 6.13 shall be in addition to, and not in substitution for, any other rights that such persons may have under the certificate or articles of incorporation, bylaws or other equivalent organizational documents, any and all indemnification agreement of or entered into by the Company or any of its Subsidiaries, or applicable Laws.

6.14Obligations of Merger Sub.  Parent shall take all action necessary to cause Merger Sub and the Surviving Corporation to perform their respective obligations under this Agreement and to consummate the transactions contemplated by this Agreement, including the Merger, upon the terms and subject to the conditions set forth in this Agreement.

6.15Insurance Policies.  The Company shall take all actions reasonably necessary to ensure that all of its current and legacy insurance policies are available for the benefit of the Surviving Corporation, including with respect any instances where an occurrence and/or claim takes place before the Effective Time and is not made known until after the Effective Time.

IV.    PURCHASE PERIODS

A.    Shares of Common Stock shall be offered for purchase under the Plan through a series of successive purchase periods until such time as (i) the maximum number of shares of Common Stock available for issuance under the Plan shall have been purchased or (ii) the Plan shall have been sooner terminated in accordance with Article VIII.

B.    The Plan shall be implemented in a series of successive purchase periods, each to be of a duration of six (6) months. The initial purchase period will begin on June 1, 1994 and end on the last U.S. business day in November 1994.

E.    The acquisition of Common Stock through plan participation for any purchase period shall neither limit nor require the acquisition of Common Stock by the Participant in any subsequent purchase period.

2 Rev. May 19, 2014

V.    ELIGIBILITY AND PARTICIPATION

A.Any Eligible Employee on a given Entry Date shall be eligible to participate in the Plan.

B.Each Eligible Employee of each Foreign Subsidiary participating in the Plan may join the Plan in accordance with the following provisions:

-    An individual who is an Eligible Employee on a given Entry Date may enter that purchase period on such Entry Date, provided he/she enrolls in the purchase period on or before such Entry Date in accordance with Section V.C below. Should any such Eligible Employee not enter the purchase period on or before the given Entry Date, then he/she may not subsequently join that particular purchase period on any later date.

-    An individual who is an Eligible Employee but was not employed on a given Entry Date may not participate in that purchase period but will be eligible to join the Plan on the next Entry Date thereafter provided that he or she is then an Eligible Employee.

C.    To participate for a particular purchase period, the Eligible Employee must complete the enrollment forms prescribed by the Plan Administrator (including a purchase agreement and a payroll deduction authorization) and file such forms with the Plan Administrator (or its designate) at least five U.S. business days before the start date of that purchase period.

D.    The payroll deduction authorized by the Participant shall be collected under the Plan in the currency in which paid by the Foreign Subsidiary and may be any multiple of one percent (1%) of the Earnings paid to the Participant during each purchase period, up to a maximum of ten percent (10%). Any changes or fluctuations in the exchange rate at which the currency collected from the Participant through such payroll deductions is converted into U.S. Dollars on each purchase date under the Plan shall be borne solely by the Participant. The deduction rate so authorized shall continue in effect for the entire purchase period and for each successive purchase period, except to the extent such rate is changed in accordance with the following guidelines:

-    The Participant may, at any time during the purchase period, reduce his/her rate of payroll deduction. Such reduction shall become effective as soon as possible after filing of the requisite reduction form with the Plan Administrator (or its designate), but the Participant may not effect more than one such reduction during the same purchase period.

-    The Participant may, prior to the start date of any subsequent purchase period, increase or decrease the rate of his/her payroll deduction by filing the appropriate form with the Plan Administrator (or its designate). The new rate (which may not exceed the ten percent (10%) maximum) shall become effective as of the start date of the new six (6)-month purchase period.

Payroll deductions will automatically cease upon the termination of the Participant's purchase right in accordance with the applicable provisions of Section VII below.

3 Rev. May 19, 2014

VI.    STOCK SUBJECT TO PLAN

A.    The Common Stock purchasable under the Plan shall, solely in the discretion of the Microchip Board, be made available from authorized but unissued shares of Common Stock or from shares of Common Stock reacquired by Microchip, including shares of Common Stock purchased on the open market. The total number of shares reserved under the Plan prior to January 2007 is 348,593 shares, plus beginning January 1, 2007, and each January 1 thereafter during the term of the Plan, an automatic annual increase in shares reserved of one tenth of one percent (0.1%) of the then outstanding shares of Microchip Common Stock. The total number of shares which may be issued under the Plan shall not exceed the number reserved.

B.    In the event any change is made to the outstanding Common Stock by reason of any stock dividend, stock split, combination of shares or other change affecting such outstanding Common Stock as a class without Microchip's receipt of consideration, appropriate adjustments shall be made by the Microchip Board of Directors to (i) the class and maximum number of securities issuable over the term of the Plan, (ii) the class and maximum number of securities purchasable per Participant during any one purchase period and (iii) the class and number of securities and the price per share in effect under each purchase right at the time outstanding under the Plan. Such adjustments shall be designed to preclude the dilution or enlargement of rights and benefits under the Plan.

VII.    PURCHASE RIGHTS

An Eligible Employee who participates in the Plan for a particular purchase period shall have the right to purchase shares of Common Stock upon the terms and conditions set forth below and shall execute a purchase agreement incorporating such terms and conditions and such other provisions (not inconsistent with the Plan) as the Plan Administrator may deem advisable.

Purchase Price. Common Stock shall be issuable at the end of each purchase period at a purchase price equal to eighty-five percent (85%) of the lower of (i) the fair market value per share on the start date of that purchase period or (ii) the fair market value per share on the last U.S. business day of that purchase period.

Valuation. The fair market value per share of Common Stock on any relevant date under the Plan shall be the closing selling price per share of Common Stock on that date, as officially quoted on the

______________________

¹ Adjusted to reflect: (i) the three-for-two stock split of the outstanding Common Stock effected in November 1994; (ii) the three-for-two stock split of the outstanding Common Stock effected in January 1997; (iii) the 10,000 share increase authorized by the Board of Directors on April 25 1997; (iv) the three-for-two stock split of the outstanding Common Stock effected in January 2000; (v) the three-for-two stock split of the outstanding Common Stock effected in September 2000; (vi) the three-for-two stock split of the outstanding Common Stock effected in May 2002; (vii) the 25,000 share increase authorized by the Board of Directors on March 3, 2003; and (viii) the 100,000 share increase authorized by the Board of Directors on August 20, 2004.

²(i)OnFebruary 13, 2007 the Board of Directors authorized the automatic 216,038 share increase; (ii) on February 11, 2008, the Board of Directors authorized the automatic 189,013 share increase; (iii) on February 27, 2009 the Board of Directors authorized the automatic 182,046 share increase; (iv) on February 22, 2010 the Board of Directors authorized the automatic 184,234 share increase; (v) on February 18, 2011 the Board of Directors authorized the automatic 188,306 share increase, and (vi) on February 13, 2012 the Board of Directors authorized the automatic 192,054 share increase. There was no share increase in 2013 and 2014.

4 Rev. May 19, 2014

Nasdaq Global Select Market. If there is no quoted selling price for such date, then the closing selling price per share of Common Stock on the next day for which there does exist such a quotation shall be determinative of fair market value.

Number of Purchasable Shares.

-    The number of shares purchasable per Participant during each purchase period shall be determined as follows: first, the payroll deductions in the currency in which collected from the Participant during that purchase period shall be converted into U.S. Dollars on the last U.S. business day of the purchase period at the exchange rate in effect on that day; then, the U.S. Dollar amount calculated for the Participant on the basis of such exchange rate shall be divided by the purchase price in effect for such period to determine the number of whole shares of Common Stock purchasable on the Participant's behalf for that purchase period.

-    However, no Participant may, during any one purchase period, purchase more than one thousand eight hundred ninety-nine (1,899) shares of Common Stock.

-    And any provisions of the Plan to the contrary notwithstanding, no Participant shall be granted an option under the Plan (i) to the extent that, immediately after the grant, such Participant (or any other person whose stock would be attributed to such Participant) would own capital stock of Microchip and/or hold outstanding options to purchase such stock possessing five percent (5%) or more of the total combined voting power or value of all classes of the capital stock of Microchip or of any Subsidiary, or (ii) to the extent that his or her rights to purchase stock under all employee stock purchase plans of Microchip and its subsidiaries accrues at a rate which exceeds $25,000.00 worth of stock (determined at the fair market value of the shares at the time such option is granted) for each calendar year in which such option is outstanding at any time.

Payment. Payment for the Common Stock purchased under the Plan shall be effected by means of the Participant's authorized payroll deductions in the currency in which paid by the Foreign Subsidiary. Such deductions shall begin with the first full payroll period beginning with or immediately following the start date of the purchase period and shall (unless sooner terminated by the Participant) continue through the pay day ending with or immediately prior to the last day of such purchase period. The amounts so collected shall be credited to the Participant's book account under the Plan, but no interest shall be paid on the balance from time to time outstanding in such account. The amounts collected from a Participant may be commingled with the general assets of the Foreign Subsidiary or Microchip and may be used for general corporate purposes. However, all purchases of Common Stock under the Plan shall be made in U.S. Dollars on the basis of the exchange rate in effect on the last day of each purchase period.

Termination of Purchase Right. The following provisions shall govern the termination of outstanding purchase rights:

-    A Participant may, at any time prior to the last five (5) business days of the Foreign Subsidiary falling within the purchase period, terminate his/her outstanding purchase right by filing the prescribed notification form with the Plan Administrator. No further payroll deductions shall be collected from the Participant with respect to the terminated purchase right, and any payroll deductions collected for the purchase period in which such termination occurs shall, at the Participant's election, be immediately refunded in the currency in which paid by the Foreign

5 Rev. May 19, 2014

Subsidiary or held for the purchase of shares at the end of such purchase period. If no such election is made at the time the termination notice is filed, then the Participant's payroll deductions shall be refunded as soon as possible after the termination date of his/her purchase right.

-    The termination of such purchase right shall be irrevocable, and the Participant may not subsequently rejoin the purchase period for which the terminated purchase right was granted. In order to resume participation in any subsequent purchase period, such individual must re-enroll in the Plan (by making a timely filing of a new purchase agreement and payroll deduction authorization) on or before the date he/she is first eligible to join the new purchase period.

-    If the Participant ceases to remain an Eligible Employee while his/her purchase right is outstanding, then such purchase right shall immediately terminate, and the payroll deductions collected from such Participant for the purchase period shall be promptly refunded in the currency in which paid by the Foreign Subsidiary to the Participant. However, should the Participant's cessation of Eligible Employee status occur by reason of death or permanent disability, then such individual (or the personal representative of a deceased Participant) shall have the following election, exercisable up until the last day of the purchase period:

-    to withdraw all of the Participant's payroll deductions for such purchase period, in the currency in which paid by the Foreign Subsidiary, or

-    to have such funds held for the purchase of shares at the end of the purchase period.

If no such election is made, then such funds shall be refunded as soon as possible after the end of the purchase period. In no event, however, may any payroll deductions be made on the Participant's behalf following his/her cessation of Eligible Employee status.

Stock Purchase. Shares of Common Stock shall automatically be purchased on behalf of each Participant (other than Participants whose payroll deductions have previously been refunded in accordance with the Termination of Purchase Right provisions above) on the last U.S. business day of each purchase period. The purchase shall be effected as follows: first, each Participant's payroll deductions for that purchase period (together with any carryover deductions from the preceding purchase period) shall be converted from the currency in which paid by the Foreign Subsidiary into U.S. Dollars at the exchange rate in effect on the purchase date, and then the amount of U.S. Dollars calculated for each Participant on the basis of such exchange rate shall be applied to the purchase of whole shares of Common Stock (subject to the limitation on the maximum number of purchasable shares set forth above) at the purchase price in effect for such purchase period. Any payroll deductions not applied to such purchase because they are not sufficient to purchase a whole share shall be held for the purchase of Common Stock in the next purchase period. However, any payroll deductions not applied to the purchase of Common Stock by reason of the limitation on the maximum number of shares purchasable by the Participant during the purchase period shall be promptly refunded to the Participant in the currency in which paid by the Foreign Subsidiary.

Proration of Purchase Rights. Should the total number of shares of Common Stock which are to be purchased pursuant to outstanding purchase rights on any particular date exceed the number of shares then available for issuance under the Plan, the Plan Administrator shall make a pro-rata allocation of the available shares on a uniform and nondiscriminatory basis, and the payroll deductions of each Participant, to the extent in excess of the aggregate purchase price payable for the Common Stock pro-rated to such individual, shall be refunded to such Participant in the currency in which paid by the Foreign Subsidiary.

6 Rev. May 19, 2014

Rights as Stockholder. A Participant shall have no stockholder rights with respect to the shares subject to his/her outstanding purchase right until the shares are actually purchased on the Participant's behalf in accordance with the applicable provisions of the Plan. No adjustments shall be made for dividends, distributions or other rights for which the record date is prior to the date of such purchase.

A Participant shall be entitled to receive, as soon as practicable after the end of each purchase period, a stock certificate (as evidenced by the appropriate entry on the books of Microchip or of a duly authorized transfer agent of Microchip) for the number of shares purchased on the Participant's behalf. Such certificate will be issued in "street name" for immediate deposit in a designated brokerage account. Until the stock certificate evidencing such Shares is issued no right to vote or receive dividends or any other rights as a stockholder shall exist. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued.

Assignability. No purchase right granted under the Plan shall be assignable or transferable by the Participant other than by will or by the laws of descent and distribution following the Participant's death, and during the Participant's lifetime the purchase right shall be exercisable only by the Participant.

Change in Ownership. Should any of the following transactions (a "Corporate Transaction") occur during the purchase period:

(i)    a merger or other reorganization in which Microchip will not be the surviving corporation (other than a reorganization effected primarily to change the State in which Microchip is incorporated), or

(ii)    a sale of all or substantially all of Microchip's assets in liquidation or dissolution of Microchip, or

(iii)    a reverse merger in which Microchip is the surviving corporation but in which more than fifty percent (50%) of Microchip's outstanding voting stock is transferred to person or persons different from those who held the stock immediately prior to such merger, then all outstanding purchase rights under the Plan shall automatically be exercised immediately prior to the effective date of such Corporate Transaction by applying the payroll deductions of each Participant for the purchase period in which such Corporate Transaction occurs to the purchase of whole shares of Common Stock at eighty-five percent (85%) of the lower of (i) the fair market value of the Common Stock on the start date of the purchase period in which such Corporate Transaction occurs or (ii) the fair market value of the Common Stock immediately prior to the effective date of such Corporate Transaction. Payroll deductions shall be converted from the currency in which paid by the Foreign Subsidiary into U.S. Dollars on the basis of the exchange rate in effect on the purchase date, and the applicable share limitation of Article VII shall continue to apply to each such purchase. Should Microchip sell or otherwise dispose of its ownership interest in any Foreign Subsidiary participating in the Plan, whether through merger or sale of all or substantially all of the assets or outstanding capital stock of that Foreign Subsidiary, then a similar exercise of outstanding purchase rights shall be effected immediately prior to the effective date of such disposition, but only to the extent those purchase rights are attributable to the employees of such Foreign Subsidiary.

Microchip shall use its best efforts to provide at least ten (10) days advance written notice of the occurrence of any such Corporate Transaction, and the Participants shall, following the receipt of such

7 Rev. May 19, 2014

notice, have the right to terminate their outstanding purchase rights in accordance with the applicable provisions of this Article VII.

VIII.    AMENDMENT AND TERMINATION

The Plan has been established voluntarily by Microchip. The Microchip Board of Directors may alter, amend, suspend or discontinue the Plan with respect to one or more Foreign Subsidiaries following the end of any purchase period. The Microchip Board may also terminate the Plan in its entirety immediately following the end of any purchase period. In such event, no further purchase rights shall thereafter be granted or exercised, and no further payroll deductions shall thereafter be collected, under the Plan.

IX.    GENERAL PROVISIONS

A.    The Plan shall become effective on the designated effective date for each Foreign Subsidiary, provided Microchip shall have complied with all applicable requirements of the Securities Act of 1933 (as amended), all applicable listing requirements of any securities exchange on which shares of the Common Stock are listed and all other applicable requirements established by law or regulation.

B.    The Plan shall terminate upon the earlier of (i) the last U.S. business day in November 2014 or (ii) the date on which all shares available for issuance under the Plan shall have been sold pursuant to purchase rights exercised under the Plan.

C.    All costs and expenses incurred in the administration of the Plan shall be paid by the Foreign Subsidiary.

D.Neither the action of Microchip or the Foreign Subsidiary in establishing the Plan, nor any action taken under the Plan by the Microchip Board or the Plan Administrator, nor any provision of the Plan itself shall constitute any form of employment contract, be construed so as to grant any person the right to remain in the employ of the Foreign Subsidiary for any period of specific duration, and except where expressly prohibited by applicable law such person's employment may be terminated at any time, with or without cause.

E.    Participation in the Plan is voluntary and occasional and does not create any contractual or other right to participate in the Plan in the future, or benefits in lieu of participation in the Plan, even if the Participant has continually participated in the Plan in the past.

F.    Participation in the Plan does not constitute normal or expected salary or compensation for any purposes, including but not limited to, calculating any severance, resignation, termination, redundancy, end of service payments, bonuses, long-term service awards, pension or retirement benefits or similar payments and in no event should be considered as compensation for, or relating in any way to past services for Microchip or the Foreign Subsidiary.

G.Microchip, Foreign Subsidiaries and the Plan Administrator must collect, use, and transfer personal data of Participants as described in this subsection in order to administer the Plan. By participating in the Plan, the Participant is consenting to the collection, transfer and use of personal data as generally described in this subsectionexcept where requiring such consent is expressly prohibited by local law.

8 Rev. May 19, 2014

(i)Microchip and its Foreign Subsidiaries hold certain personal information about the Participant, including, but not limited to, name, home address and telephone number, date of birth, social insurance number, salary, nationality, job title, any Shares of Common Stock or directorships held in Microchip, details of all participation in the Plan or other entitlement to Shares, for the purpose of managing and administering the Plan (“Data”).

(ii)Microchip and/or its Foreign Subsidiaries will transfer Data among themselves as necessary for the purposes of implementation, administration, and management of Participant’s participation in the Plan, and that Microchip and/or its Foreign Subsidiaries may each further transfer Data to identified third parties assisting them in the implementation, administration, and management of the Plan (“Data Recipients”).

(iii)These Data Recipients may be located in Participant’s country of residence or elsewhere, such as the United States. By participating under this Plan, the Participant authorizes the Data Recipients to receive, possess, use, retain, and transfer Data in electronic or other form, for the purposes of implementing, administering, and managing Participant’s participation in the Plan, including any transfer of such Data, as may be required for Plan administration and/or the subsequent holding of Shares on Participant’s behalf, to a broker or third party with whom the Shares acquired on purchase may be deposited.

(iv)    Participant may, at any time, review the Data, request that any necessary amendments be made to it, or withdraw Participant’s consent herein in writing by contacting Microchip. Withdrawing consent may affect Participant’s ability to participate in the Plan.

MICROCHIP TECHNOLOGY INCORPORATED

INTERNATIONAL STOCK PURCHASE AGREEMENT

1.I hereby elect to participate in the Microchip Technology Incorporated (the “Company”) International Employee Stock Purchase Plan (the “IESPP”) until such time as I elect to withdraw from the IESPP either by written notification to the Plan Administrator, my employment status changes, or termination of the IESPP by the Company, and I hereby subscribe to purchase shares of common stock of Microchip Technology Incorporated (“Common Stock”) in accordance with the provisions of this International Stock Purchase Agreement, including any appendix for my country (the “Appendix” and together with the International Stock Purchase Agreement, the “Agreement”) and the IESPP. I hereby authorize payroll deductions from each of my paychecks during the time in which I participate in the IESPP in the 1% multiple of my Earnings (not to exceed a maximum of 10%) specified in my attached Enrollment Form. Capitalized terms not defined herein shall have the meaning ascribed to them in the IESPP.

2.I understand that the IESPP has a six-month offering period. IESPP offering periods begin on the first business day of June and December of each year, and my participation will automatically remain in effect from one offering period to the next offering period in accordance with my payroll deduction authorization, unless I withdraw from the IESPP or change the rate of my payroll deduction or my employment status changes.

3.I understand that my payroll deductions will be accumulated for the purchase of shares of Common Stock on the last business day of each offering period of participation. The purchase price per share will be equal to 85% of the lower of (i) the fair market value per share of Common Stock on the start date of the six-month offering period or (ii) the fair market value per share on the purchase date on the last business day of the offering period.

4.I understand that I can withdraw from the IESPP at any time prior to the last 5 business days of an offering period and elect either to have the Company refund all my payroll deductions for that period or to have such payroll deductions applied to the purchase of Common Stock at the end of such period. However, I may not rejoin that particular six-month offering period at any later date. Upon my termination of employment or change to ineligible employee status, my participation in the IESPP will immediately cease and all my payroll deductions for the six-month period in which such termination or change occurs will be refunded. Should I die or become disabled while an IESPP participant, payroll deductions will automatically cease on my behalf, and I or my estate may, at any time prior to the last 5 business days of the offering period in which I die or become disabled, elect to have my payroll deductions for that period applied to the purchase of Common Stock at the end of that period; otherwise, those deductions will be refunded. I further understand that I may reduce my rate of my payroll deductions on one occasion during a six-month offering period, but that I may only increase my rate of payroll deductions at the beginning of a new six-month offering period.

5.I understand that my shares will be placed in a brokerage account at the end of each six-month offering period of participation. The account will be opened in the Participant's name.

6.I understand that the Company has the right, exercisable in its sole discretion, to amend or terminate the IESPP at any time, with such amendment or termination to become effective immediately following the purchase of shares at the end of any current six-month offering period of participation. Should the Company elect to terminate the IESPP, I will have no further rights to purchase shares of Common Stock pursuant to this Agreement.

7.I understand that the IESPP sets forth restrictions (i) limiting the maximum number of shares which I may purchase per the six-month offering period of participation and (ii) prohibiting me from purchasing more than $25,000 worth of Common Stock per calendar year.

8.Tax Obligations. Regardless of any action the Companyor my employer (the “Employer”) takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related items related to my participation in the IESPP and legally applicable to me (“Tax-Related Items”), I acknowledge that the ultimate liability for all Tax-Related Items is and remains my responsibility and may exceed the amount actually withheld by the Company or my Employer. I further acknowledge that the Company and/or my Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of my participation in the IESPP, including, but not limited to, the grant of the purchase right, the purchase of Common Stock under the IESPP, the subsequent sale of shares of Stock acquired under the IESPP and the receipt of any dividends; and (2) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the purchase right to reduce or eliminate my liability for Tax-Related Items or achieve any particular tax result. Further, if I have become subject to tax in more than one jurisdiction between the date my participation began and the date of any relevant taxable event, I acknowledge that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Rev. November 2013 Page 1

Prior to any relevant taxable or tax withholding event, as applicable, I will pay or make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, I authorize the Company and/or the Employer, or their respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following:

(a)withholding from my wages or other cash compensation paid to me by the Company and/or the Employer; or

(b)withholding from proceeds of the sale of shares of Common Stock acquired at purchase either through a voluntary sale or through a mandatory sale arranged by the Company (on my behalf pursuant to this authorization); or

(c)withholding in shares of Common Stock to be issued at purchase.

To avoid negative accounting treatment, the Company may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding amounts or other applicable withholding rates. If the obligation for Tax-Related Items is satisfied by withholding in shares of Common Stock, for tax purposes, I will be deemed to have been issued the full number of shares of Common Stock subject to the exercised purchase right, notwithstanding that a number of shares of Common Stock are held back solely for the purpose of paying the Tax-Related Items due as a result of my participation in the IESPP.

Finally, I shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of my participation in the IESPP that cannot be satisfied by the means previously described. The Company may refuse to purchase shares of Common Stock on my behalf under the IESPP and refuse to deliver the shares of Common Stock if I fail to comply with my obligations in connection with the Tax-Related Items.

9.Nature of Grant. By participating in the IESPP, I acknowledge, understand and agree that:

(a)the IESPP is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated by the Company at any time;

(b)the grant of the purchase rights is voluntary and occasional and does not create any contractual or other right to receive future grants of purchase rights, or benefits in lieu of purchase rights, even if purchase rights have been granted repeatedly in the past;

(c)all decisions with respect to future grants of purchase rights, if any, will be at the sole discretion of the Company;

(d)my participation in the IESPP shall not create a right to further employment with the Employer and shall not interfere with the ability of the Employer to terminate my employment relationship at any time where not otherwise expressly prohibited by applicable law;

(e)I am voluntarily participating in the IESPP;

(f)the purchase rights and the shares of Common Stock subject to the purchase rights are an extraordinary item that does not constitute compensation of any kind for services of any kind rendered to the Company or the Employer, and which is outside the scope of my employment contract, if any;

(g)the purchase rights and the shares of Common Stock subject to the purchase rights are not intended to replace any pension rights or compensation;

(h)the purchase rights and the shares of Common Stock subject to the purchase rights are not part of normal or expected compensation or salary for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end of service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments and in no event should be considered as compensation for, or relating in any way to, past services for the Company, the Employer or any Foreign Subsidiary;

(i)the grant of purchase rights and my participation in the IESPP will not be interpreted to form an employment contract or relationship with the Company or any subsidiary or affiliate of the Company;

(j)the future value of the underlying shares of Common Stock is unknown and cannot be predicted with certainty;

Rev. November 2013 Page 2

of my employment with the Company or the Employer (for any reason whatsoever and whether or not in breach of local labor laws) and in consideration of the grant of the purchase rights under the IESPP to which I am otherwise not entitled, I irrevocably agree never to institute any claim against the Company or any Foreign Subsidiary, waive the ability, if any, to bring any such claim regarding the forfeiture of purchase rights under the IESPP and release the Company and the Employer from any such claim; if, notwithstanding the foregoing, any such claim is allowed by a court of competent jurisdiction, then, by participating in the IESPP, I shall be deemed irrevocably to have agreed not to pursue such claim and agree to execute any and all documents necessary to request dismissal or withdrawal of such claims; and

(l)in the event of termination of my employment (whether or not in breach of local labor laws), my right to participate in and to purchase shares of Common Stock under the IESPP, if any, will terminate effective as of the date that I am no longer actively employed and will not be extended by any notice period mandated under local law (e.g., active employment would not include a period of “garden leave” or similar period pursuant to local law); the Plan Administrator shall have the exclusive discretion to determine when I am no longer actively employed for purposes of my participation in the IESPP.

10.No Advice Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding my participation in the IESPP, or my acquisition or sale of the underlying shares of Common Stock. I am hereby advised to consult with my own personal tax, legal and financial advisors regarding my participation in the IESPP before taking any action related to the IESPP.

I understand that I may request a list with the names and addresses of any potential recipients of the Data by contacting my local human resources representative. I understand that Data will be held only as long as is necessary to implement, administer and manage my participation in the IESPP. I understand that I may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents herein, in any case without cost, by contacting in writing the Company's human resources department.

The following provision modifies Section V(D) of the IESPP, Section 1 of the Enrollment Form and Sections 1-3 of this Agreement:

I understand that I am not able to participate in the IESPP by means of payroll deductions taken from my Earnings in RMB each pay period due to certain exchange control laws and regulations in the PRC and other legal restrictions, and therefore, to participate in the IESPP, I agree that if I wish to participate in the IESPP, I agree to contribute towards the purchase of shares by a means other than payroll deductions. At the direction of the Company, I agree to contribute to the purchase of shares in the IESPP through contributions in USD, or contributions converted by me from RMB to USD, in an amount equal to the percentage of my Earnings (from 1% to 10%) specified in my attached Enrollment Form for the particular offering period.

Due to exchange control laws and regulations in the PRC, I understand and agree that any shares of Common Stock acquired at exercise of the purchase rights under the IESPP will be deposited in an account established for me by the Company (the “Account”) with E*Trade Financial or any successor broker designated by Company, in its sole discretion (the “Designated Broker”).

In addition, if any dividends related to shares of Common Stock acquired under the IESPP are issued, I understand that, such dividends may, at the Company’s sole discretion, be deposited into an Account with the Designated Broker, or re-invested by Company on my behalf.

Moreover, if the proceeds from the sale of the shares of Common Stock are converted to local currency, I acknowledge that the Company and any Foreign Subsidiary are under no obligation to secure any particular currency conversion rate and may face delays in converting the proceeds to local currency due to exchange control restrictions in the PRC. I agree to bear the risk of any fluctuation in the U.S. dollar/local currency exchange rate between the date I realize U.S. dollar proceeds from my participation in the IESPP and the date that I receive cash proceeds converted to local currency. Finally, I agree to comply with any other requirements that may be imposed by the Company in the future to facilitate compliance with exchange control requirements in the PRC.

Re: Agreed Tax Ruling-Calculation of Tax re the Benefit to Employees under the Employee

Stock Purchase Plan - Microchip Technologies Israel Ltd.

(With reference to your request of December 10, 2013)

1 The facts as presented by you:

1.1 Microchip Technologies Israel Ltd., company no. 514944107, withholding file 923692313 (hereinafter: the"Company") is an Israeli resident private company.

1.2 The Company is a subsidiary of Microchip Technology, Inc. (hereinafter: the "Parent”), a corporation whose shares are traded on the NASDAQ. The Parent develops and manufactures semiconductor products for a wide range of uses.

1.3 The Parent approved the International Employee Stock Purchase Plan (hereinafter: the “ESPP”). Among others, employees of the Company who are not "controlling shareholders" as defined in section 102(a) of the Income Tax Ordinance (hereinafter: the"Ordinance") are eligible to participate in the ESPP.

1.4 The main provisions of the ESPP are as follows:

1.4.1 The ESPP provides for consecutive savings periods (hereinafter: the "Savings Periods"), during which eligible employees can participate in the ESPP and be granted the right to purchase shares in the Parent (hereinafter: the "Shares"). The last day of each Savings Period is referred to as the purchase date (hereinafter: the "Purchase Date"). The six month Saving Periods begin on the first trading day after June 1^st and December 1^st of each year. The first Savings Period for Israeli employees began on December 1, 2013.

1.4.2 Employees of the Company are eligible to purchase ordinary shares of the Parent at a 15% discount of the lower of:

a. The market price of the Shares on the first date of the Savings Period; or

b. The market price of the Shares on the last date of the Savings Period (hereinafter: the "Exercise Price").

1.4.3 For the first Savings Period, the employees participating in the ESPP received an automatic right to purchase Shares via withholding from each employee's salary (hereinafter: the "Savings Amount"). The employee is allowed to pay an amount of between 1% and 10% of his net salary after withholding of taxes during the Savings Period, and that Savings Amount will be used solely for the purchase of Shares and will not exceed 10% of the employee’s monthly base salary. The employee may elect to decrease the percentage of cash

Rev. April 2014 Page A-5

compensation that he authorizes for use during the Savings Period. Neither the Company nor the Parent will pay any interest on the Savings Amount.

1.4.4 Each employee may terminate his participation in the ESPP at any time in the manner proscribed by the Parent. Should an employee cancel his participation prior to the end of the Savings Period or at any later time, the entire sum of the accrued salary deduction will be returned as soon as possible to the employee, without interest. The employee is not permitted to withdraw less than the entire salary deduction amount that has accrued to him. In the event that the employee decides to terminate his participation in the ESPP, the employee is permitted to re-enroll during any subsequent Savings Period via submission of a new enrollment form to the Company prior to the relevant Purchase Date. The Company and the Parent will not pay interest on the Savings Amount.

1.4.5 The ESPP contains quantitative limitations regarding the number of Shares that each employee is entitled to purchase. In any event, in any calendar year, an employee may not purchase more than the number of Shares equal to $25,000 divided by the market value of the Shares on the relevant Purchase Date.

1.4.6 Attached as Appendix A hereto is the ESPP and its conditions per your submissions.

2 The Request:

2.1. The employee's enrollment in the ESPP will not constitute a tax event and will not be subject to tax on that date.

2.2. On the date the options are exercised and the employee purchases the Shares, the employee will be subject to tax for the benefit resulting from the difference between the market value of the Shares at the close of trading on the Purchase Date and the Exercise Price the employee actually paid. The tax rate will be the employee's marginal tax rate according to the tax liability for employee grants under the non-trustee track. The tax will be withheld at the source by the Company.

2.3. On the date of sale of the Shares by the employee, the Parent and/or the Company will not withhold tax at source, and the employee will be taxed according to Section E of the Ordinance.

3. The tax arrangement and its conditions:

Relying on the facts provided by you and detailed in section 1 above, the Income Tax Authority approves the tax arrangement relating to the ESPP on compliance with the following conditions:

3.1. This tax arrangement applies to the ESPP, whose first Savings Period commenced on December 1, 2013, and will continue to apply until the termination of the ESPP by the Parent, and for so long as the provisions of the law are not changed, and only if the Company and the employees will act in accordance with the provisions of this tax arrangement.

3.2. Each term in this tax arrangement shall have the meaning ascribed to it in Part E-1 of the Ordinance, unless otherwise expressly provided.

3.3. The provisions of section 102(c)(2) of the Ordinance and the Income Tax Rules (Tax Benefits for Employee Share Allotments), 2003 (hereinafter: the "Rules") will apply to the grant of the ESPP to the employees of the Company.

Rev. April 2014 Page A-6

3.4. The Company will not take any tax deductions related to the ESPP, regardless of whether the employees of the Company participate in the tax agreement.

3.5. Notwithstanding section 3.2 above, the end of each Purchase Period will be deemed a "realization" for the purpose of section 102(c)(2) of the Ordinance (hereinafter: the "Realization Date"), and the following provisions will apply:

3.5.1 All Shares that an employee received on the Realization Date will be deemed sold according to the closing price of the Shares on the Realization Date (hereinafter: the "Share Price").

3.5.2 The employee will be liable for employment income according to section 2(2) of the Ordinance for the difference between the Share Price and the Exercise Price that the employee paid on the Realization Date, multiplied by the total Shares purchased by the broker in his name (hereinafter: the "Value of the Benefit").

3.5.3 On the Realization Date, the Company will withhold tax for the Value of the Benefit and will transfer the relevant withholding to the Assessing Officer, as required by section 9(e) of the Rules.

3.5.4 Employees will be deemed residents of Israel until the date on which the Shares are actually sold, in respect of the income from the ESPP that is the subject of this tax agreement. The aforesaid will not apply to Savings Periods after an employee is no longer a resident of Israel, including if the employee has secured approval from the ITA on the termination of his Israeli residency or if the Company secures a tax agreement with respect to severing Israeli residency of its employees.

3.5.5 On the actual date of sale the Shares, Part E of the Ordinance will apply to the employee, and the price of the Shares and the end of the Purchase Period (as stated in section 3.4.1 above) will be deemed the original price of the Shares on the Purchase Date.

3.5.6 For the avoidance of doubt, it is clarified that the reporting and tax payment obligations for the income described in section 3.5.5 above, on the actual date of sale, are the sole obligations of the employees.

3.6. This tax agreement is conditioned on compliance with the law and this agreement. This agreement is given on reliance on the representations that you made to us. If it is later discovered that the details you provided in the context of the request are not accurate, or substantively incomplete, and/or one of the conditions is not complied with, the following consequences will result: the employees that purchase Shares on the Purchase Date will be liable for income tax as employment income under section 2(2) of the Ordinance on the actual date of sale of the Shares, at the highest price of the Shares from the beginning of the Savings Period until the sale of the Shares to an unrelated third party, as defined by section 88 of the Ordinance, including interest and linkage differentials from the grant date of the Shares.

3.7. This tax agreement does not amount to an assessment or approval of the facts as presented by you. The facts as presented by you shall be examined by the Assessing Officer via his examination of the Company and/or the employees participating in the ESPP, as applicable.

3.8. This tax agreement is valid from the Offering Period beginning on December 1, 2013 and through December 31, 2018. Following that period, you may request an extension from the ITA (if any).

Rev. April 2014 Page A-7

3.9. Within 60 days of the date hereof, and within 60 days from a new employee's enrollment in the ESPP, as applicable, the Company and the employees participating in the ESPP will submit a declaration in the form provided in Exhibit B to this tax agreement. Section 3.6 above will apply to an employee who does not sign the declaration. The Company and the employees' declarations will be valid with respect to the ESPP for all Offering Periods that are the subject of this tax agreement, and accordingly for the period stated in section 3.1 above. The Company will submit a list of the employees that did not participate in this tax agreement to the Assessing Officer within 60 days of the receipt of this tax agreement or within 60 days of the beginning of each Offering Period, as applicable.

Re: Agreed Tax Ruling-Microchip Technology Israel Ltd.

Pursuant to section 3.9 of the Tax Ruling dated February 4, 2014, “Tax Ruling by Agreement - Calculation of Tax re the Benefit to Employees of Microchip Technology Israel Ltd.” (the “Tax Ruling”), I, the undersigned employee, declare that I understand the Tax Ruling, will act in accordance with it, and will not request to change it and/or annul it, and/or replace it, and/or will not request additional tax benefits other than those provided in this Tax Ruling.

In addition, I understand that should I sell the shares of Common Stock (as defined under the IESPP) purchased under the IESPP more than three (3) days after I purchase such shares, I will be required, by Israeli law, to report on all profits and/or losses from such sales on my Annual Return, to report to the Tax Authorities according to section 91(d), and to make advanced tax payments as required by law.

Additionally, I understand that I will be required to file an Annual Return to the Assessing Officer even if I do not currently file an Annual Return.

I also declare that I understand that a failure to file an Annual Return or a failure to pay tax, as required by Israeli law, on any income from sale of shares of Common Stock that I purchased under the IESPP is a criminal offense.

Data Privacy Notice. The following provision replaces paragraph 12 of the Agreement:

I hereby explicitly and unambiguously consent to the collection, use, processing and transfer, in electronic or other form, of my personal data as described in this provision of this Appendix by and among, as applicable, the Employer, the Company and any Foreign Subsidiary for the exclusive purpose of implementing, administering, and managing my participation in the IESPP.

I understand that the Employer, the Company and/or any Foreign Subsidiary may hold certain personal information about me, including, without limitation, my name, home address and telephone number, date of birth, social insurance or other identification number, salary, nationality, job title, any shares or directorships held in the Company or a Foreign Subsidiary, details of all purchase rights, or any other entitlement to shares of Common Stock awarded, canceled, exercised, vested, unvested or outstanding in my favor, for the exclusive purpose of implementing, managing, and administering the IESPP (“Data”).

I also understand that providing the Company with Data is necessary for the performance of the IESPP and that my refusal to provide such Data would make it impossible for the Company to perform its contractual obligations and may affect my ability to participate in the IESPP. The Controller of personal data processing is Microchip Technology Incorporated at 2355 West Chandler Boulevard, Chandler, AZ 85224, U.S.A., and, pursuant to Legislative Decree no. 196/2003, its representative in Italy is Microchip Technology SRL with registered offices at Via Pablo Picasso 41, 20025 Legnano (MI) Italy.

I understand that Data will not be publicized, but it may be transferred to E*Trade Financial (or one of its affiliates) or such other stock plan service provider as may be selected by the Company in the future (any such entity, “Broker”), or other third parties involved in the management and administration of the IESPP. I understand that Data may also be transferred to the independent registered public accounting firm engaged by the Company. I further understands that the Company and/or any Foreign Subsidiary will transfer Data among themselves as necessary for the purpose of implementing, administering, and managing my participation in the IESPP, and that the Company or a Foreign Subsidiary may each further transfer Data to third parties assisting the Company in the implementation, administration, and management of the IESPP, including any requisite transfer of Data to the Broker or other third party with whom I may elect to deposit any shares of Common Stock acquired at vesting of the purchase rights. Such recipients may receive, possess, use, retain, and transfer Data in electronic or other form, for the purposes of implementing, administering, and managing my participation in the IESPP. I understand that these recipients may be located in or outside the European Economic Area, such as in the United States or elsewhere. Should the Company exercise its discretion in suspending all necessary legal obligations connected with the management and administration of the IESPP, it will delete Data as soon as it has completed all the necessary legal obligations connected with the management and administration of the IESPP.

I understand that Data processing related to the purposes specified above shall take place under automated or non-automated conditions, anonymously when possible, that comply with the purposes for which Data is collected and with confidentiality and security provisions, as set forth by applicable laws and regulations, with specific reference to Legislative Decree no. 196/2003.

The processing activity, including communication, the transfer of Data abroad, including outside of the European Economic Area, as herein specified and pursuant to applicable laws and regulations, does not require my consent thereto, as the processing is necessary to performance of contractual obligations related to implementation, administration, and management of the IESPP. I understand that, pursuant to paragraph 7 of the Legislative Decree no. 196/2003, I have the right to, without limitation, access, delete, update, correct, or terminate, for legitimate reason, the Data processing.

Furthermore, I am aware that Data will not be used for direct-marketing purposes. In addition, Data provided can be reviewed and questions or complaints can be addressed by contacting my local human resources representative.

Grant Terms Acknowledgment. By accepting the purchase rights, I acknowledge having received and reviewed the IESPP and the Agreement, including this Appendix, in their entirety and fully understand and accept all provisions of the IESPP and the Agreement, including this Appendix.

Payroll Withholding Authorization. In order to purchase Common Stock under the IESPP, I understand that I must sign the Payroll Withholding Authorization Form (attached here and distributed to me by the Company or by the Employer) in addition to this Agreement and the Enrollment Form, whereby I request and authorize the Employer to withhold from my Earnings the amount specified in the Enrollment Form. I agree that this withholding will continue until I file the prescribed notification form with the Plan Administrator notifying him/her of my withdrawal from the IESPP. I understand that payroll withholding and the purchase of Common Stock under the IESPP will not take place unless and until I sign and return the Enrollment Form to the Employer.

Acknowledgement of the Agreement. By enrolling in the IESPP, I acknowledge that I have received a copy of the IESPP and the Agreement, including this Appendix. I acknowledge further that I accept all the provisions of the IESPP and the Agreement, including this Appendix. I also acknowledge that I have read and specifically and expressly approve the terms and conditions set forth in the Nature of Grant section of the Agreement, which clearly provide as follows:

(1) my participation in the IESPP does not constitute an acquired right;

(2) the IESPP and my participation in it are offered by the Company on a wholly discretionary basis;

(3) my participation in the IESPP is voluntary; and

(4) the Company and its Foreign Subsidiaries are not responsible for any decrease in the value of any Common Stock acquired at purchase.

Labor Law Acknowledgement and Policy Statement. By accepting the grant of the purchase rights, I acknowledge that Microchip Technology Incorporated, with registered offices at 2355 West Chandler Boulevard, Chandler AZ 85224, U.S.A. is solely responsible for the administration of the IESPP. I further acknowledge that my participation in the IESPP, the grant of the purchase rights and any acquisition of Common Stock under the IESPP do not constitute an employment relationship between myself and the Company because I am participating in the IESPP on a wholly commercial basis and my sole employer is Microchip Technology Mexico, S.DE R.L. De C.V. Based on the foregoing, I expressly acknowledge that the IESPP and the benefits that I may derive from participation in the IESPP do not establish any rights between myself and the Employer, and do not form part of the employment conditions and/or benefits provided by Microchip Technology Mexico, S.DE R.L. De C.V., and any modification of the IESPP or its termination shall not constitute a change or impairment of the terms and conditions of my employment.

I further understand that my participation in the IESPP is the result of a unilateral and discretionary decision of the Company; therefore, the Company reserves the absolute right to amend and/or discontinue my participation in the IESPP at any time, without any liability to me.

Finally, I hereby declare that I do not reserve any action or right to bring any claim against the Company for any compensation or damages regarding any provision of the IESPP or the benefits derived under the IESPP, and I therefore grant a full and broad release to the Company, its Foreign Subsidiaries, affiliates, branches, representation offices, shareholders, officers, agents or legal representatives, with respect to any claim that may arise and reiterate that I do not reserve any present or future action or right against the Company, its Foreign Subsidiaries, affiliates, branches, representation offices, shareholders, officers, agents or legal representatives.

ATTACHMENT TO THIS APPENDIX FOR MEXICO

PAYROLL WITHHOLDING AUTHORIZATION FORM

FOR EMPLOYEES IN MEXICO

MICROCHIP TECHNOLOGY INCORPORATED

INTERNATIONAL EMPLOYEE STOCK PURCHASE PLAN

1.I have separately elected to participate in the Microchip Technology Incorporated International Employee Stock Purchase Plan (the “IESPP”), in order to purchase shares of common stock (“Common Stock”) of Microchip Technology Incorporated (the “Company”) in the United States of America, in accordance with the terms and conditions of the IESPP.

2.I hereby acknowledge receipt of a full copy of the IESPP and that I understand the terms, methods and consequences of participating in the IESPP.

3.In order to make the purchases of Common Stock more efficient, I hereby request and authorize my employer,Microchip Technology Mexico, S.DE R.L. De C.V. (“Employer”), to withhold from my paycheck each pay period the amount specified in my Enrollment Form. I shall have the right to decrease or increase such amount (subject to the limits set forth in the Agreement and the IESPP). This withholding will continue until I inform the Plan Administrator (as defined in the IESPP) to stop such payroll withholding by filing the prescribed notification form.

4.I hereby further request that the withholding to which the preceding paragraph refers shall be delivered by my Employer to the Company or the Plan Administrator. These amounts shall be used by the Company or the Administrator to purchase Common Stock in accordance with the terms and conditions of the IESPP and the Agreement (including the Appendix to the Agreement).

5.I acknowledge and agree that the participation of the Employer in the IESPP is limited to acting as an intermediary in delivering to the Company the amounts withheld from my paycheck each pay period. The Employer will make no additional salary payment or other compensation to me as a result of the IESPP.

6.I hereby acknowledge that the withholding I have requested is not a salary deduction or reduction; therefore, I further acknowledge receipt in full of my entire salary for each pay period during my participation in the IESPP.

7.I acknowledge that my work relationship is exclusively with my Employer and that there is no work relationship between the Company and me.

Therefore, the IESPP shall not be considered a labor benefit in my favor, and my participation in the IESPP creates no labor obligations or rights between the Company and me.

The right to purchase Common Stock under the IESPP is not part of normal or expected compensation for purposes of calculating any termination, severance, resignation, redundancy, end of service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments under my employment relationship with my Employer.

The value of the right to purchase Common Stock and any Common Stock purchased or to be purchased under the IESPP, if any, are an extraordinary item, which are outside the scope of the employment contract with my Employer, if any.

8.By enrolling in the IESPP, I accept all of its terms and conditions and, in particular, I acknowledge that:

(a) The IESPP is discretionary in nature and may be modified, amended, suspended or terminated by the Company at any time.

(b) The grant of the option to purchase shares of Common Stock under the IESPP does not create any contractual or other right to receive future grants of purchase rights, or benefits in lieu of purchase rights.

(c) All determinations with respect to any such future purchase rights, including, but not limited to, the times when rights shall be granted, the purchase price of the shares of Common

Rev. November 2013 Page 1-1

Stock, and the time or times when each right shall be exercisable, will be at the sole discretion of the Company.

(d) My participation in the IESPP is voluntary.

(e) The right to purchase Common Stock, if any, ceases upon termination of employment with my Employer for any reason except as may otherwise be explicitly provided in the IESPP.

(f) The future value of the Common Stock purchased under the IESPP is unknown and cannot be predicted with certainty.

(g) The IESPP is governed by, and subject to, the laws of the State of Arizona (excluding such state's conflict of laws provisions).

Sincerely,

Securities Law Notification. The offer to participate in the IESPP is being made pursuant to the “Qualifying Person” exemption under section 273(1)(f) of the Securities and Futures Act (Chapter 289, 2006 Ed.) (“SFA ”). The IESPP has not been lodged or registered as a prospectus with the Monetary Authority of Singapore. I should note that the right to purchase shares and/or the shares purchased are subject to section 257 of the SFA and I will not be able to make (i) any subsequent sale of shares of Common Stock in Singapore or (ii) any offer of such subsequent sale of shares of Common Stock underlying the awards in Singapore, unless such sale or offer in is made pursuant to the exemptions under Part XIII Division (1) Subdivision (4) (other than section 280) of the SFA (Chapter 289, 2006 Ed.).

SPAIN

Termination of Employment. The purchase rights provide a conditional right to shares of Common Stock and may be forfeited or affected by my termination of employment, as set forth in the Agreement. For avoidance of doubt, my rights, if any, to the purchase rights upon termination of employment shall be determined as set forth in the Agreement, including, without limitation, where (i) I am deemed to be constructively dismissed or unfairly dismissed without good cause; (ii) I am dismissed for disciplinary or objective reasons or due to a collective dismissal; (iii) I terminate employment due to a change of work location, duties or any other employment or contractual condition (except as otherwise expressly set forth in the Agreement); or (iv) I terminate employment due to the Company's or any of its Foreign Subsidiaries' unilateral breach of contract. Consequently, the termination of my employment for any of the above reasons shall be governed by paragraphs 4 and 9(k) and (l) of the Agreement, unless otherwise determined by the Company, in its sole discretion.

Labor Law Acknowledgment. By accepting the purchase rights, I acknowledge that I understand and agree to the terms and conditions applicable to participation in the IESPP and that I have received a copy of the IESPP.

I understand that the Company has unilaterally, gratuitously and discretionally decided to grant purchase rights under the IESPP to individuals who may be employees of any Foreign Subsidiary throughout the world. The decision is a limited decision that is entered into upon the express assumption and condition that any grant will not economically or otherwise bind the Company or any Foreign Subsidiary on an ongoing basis, other than as expressly set forth in the IESPP and the Agreement. Consequently, I understand that any grant is given on the assumption and condition that it shall not become a part of any employment contract (either with the Company or any Foreign Subsidiary) and shall not be considered a mandatory benefit, salary for any purposes (including severance compensation) or any other right whatsoever. Furthermore, I understand and freely accept that there is no guarantee that any benefit whatsoever shall arise from any gratuitous and discretionary grant since the future value of the purchase rights and the underlying shares of Common Stock are unknown and unpredictable. In addition, I understand that this grant would not be made but for the assumptions and conditions referred to above; thus, I understand, acknowledge and freely accept that should any or all of the assumptions be mistaken or should any of the conditions not be met for any reason, then the purchase rights shall be null and void.

Responsibility for Taxes. The following provisions supplement section 8 of the Agreement:

If payment or withholding of my income tax liability is not made within ninety (90) days of the event giving rise to such income tax liability or such other period specified in Section 222(1)(c) of the U.K. Income Tax (Earnings and Pensions) Act 2003 (the “Due Date”), the amount of any uncollected income tax liability will constitute a loan owed by me to the Employer, effective on the Due Date. I agree that the loan will bear interest at the then-current Official Rate of Her Majesty's Revenue and Customs (“HMRC”), it will be immediately due and repayable, and the Company or the Employer may recover it at any time thereafter by any of the means referred to in section 8 of the Agreement. Notwithstanding the foregoing, in the event that I am a director or executive officer of the Company (within the meaning of Section 13(k) of the U.S. Securities Exchange Act of 1934, as amended), I will not be eligible for such a loan to cover any income tax liability. In the event that I am a director or executive officer and such income tax liability is not collected from or paid by me by the Due Date, the amount of any uncollected income tax liability will constitute a benefit to me on which additional income tax and National Insurance contributions will be payable. I will be responsible for reporting and paying any income tax and national insurance contributions due on this additional benefit directly to HMRC under the self-assessment regime.

Commitments and Contingencies Disclosure [Abstract]

Contingencies

CONTINGENCIES

In the ordinary course of the Company's business, it is involved in a limited number of legal actions, both as plaintiff and defendant, and could incur uninsured liability in any one or more of them.  The Company also periodically receives notifications from various third parties alleging infringement of patents, intellectual property rights or other matters.  With respect to pending legal actions to which the Company is a party, although the outcomes of these actions are not generally determinable, the Company believes that the ultimate resolution of these matters will not have a material adverse effect on its financial position, cash flows or results of operations.  Litigation relating to the semiconductor industry is not uncommon, and the Company is, and from time to time has been, subject to such litigation.  No assurances can be given with respect to the extent or outcome of any such litigation in the future.

The Company's technology license agreements generally include an indemnification clause that indemnifies the licensee against liability and damages (including legal defense costs) arising from any claims of patent, copyright, trademark or trade secret infringement by the Company's proprietary technology.  The terms of these indemnification provisions approximate the terms of the outgoing technology license agreements, which are typically perpetual unless terminated by either party for breach. The possible amount of future payments the Company could be required to make based on agreements that specify indemnification limits, if such indemnifications were required on all of these agreements, is approximately $129 million. There are some licensing agreements in place that do not specify indemnification limits.  The Company had not recorded any liabilities related to these indemnification obligations as of March 31, 2014.

Contingent liabilities in the amount of $13.0 million were recorded in connection with the Company's April 8, 2010 acquisition of Silicon Storage Technology Inc. (SST) as an adverse outcome was determined to be probable and estimable.  One of the contingent liabilities associated with the SST acquisition was resolved in fiscal 2013 with legal settlement costs of approximately $11.5 million in excess of previously accrued amounts, which were expensed as special charges in the statement of income. At March 31, 2014, $5.7 million of the original contingent liabilities recorded were still outstanding.

Accounting Policies [Abstract]

Principles of consolidation

Principles of Consolidation

The consolidated financial statements include the accounts of Microchip Technology Incorporated and its wholly-owned subsidiaries (Microchip or the Company).  The Company does not have any subsidiaries in which it does not own 100% of the outstanding stock.  All of the Company's subsidiaries are included in the consolidated financial statements.  All significant intercompany accounts and transactions have been eliminated in consolidation.

Revenue recognition

Revenue Recognition

The Company recognizes revenue when the earnings process is complete, as evidenced by an agreement with the customer, transfer of title as well as fixed or determinable pricing and when collectability is reasonably assured.  The Company recognizes revenue from product sales to original equipment manufacturers (OEMs) upon shipment and records reserves for estimated customer returns.

Distributors worldwide generally have broad price protection and product return rights, so the Company defers revenue recognition until the distributor sells the product to their customer.  Revenue is recognized when the distributor sells the product to their end customer, at which time the sales price becomes fixed or determinable.  Revenue is not recognized upon the Company's shipment to the distributors since, due to discounts from list price as well as price protection rights, the sales price is not substantially fixed or determinable at that time.  At the time of shipment to these distributors, the Company records a trade receivable for the selling price as there is a legally enforceable right to payment, relieves inventory for the carrying value of goods shipped since legal title has passed to the distributor, and records the gross margin in deferred income on shipments to distributors on its consolidated balance sheets.

Deferred income on shipments to distributors effectively represents gross margin on the sale to the distributor at the initial shipment date; however, the amount of gross margin recognized by the Company in future periods will be less than the deferred margin as a result of credits granted to distributors on specifically identified products and customers to allow the distributors to earn a competitive gross margin on the sale of the Company's products to their end customers and price protection concessions related to market pricing conditions.

The Company sells the majority of the items in its product catalog to its distributors worldwide at a uniform list price.  However, distributors resell the Company's products to end customers at a very broad range of individually negotiated price points.  The majority of the Company's distributors' resales require a reduction from the original list price paid.  Often, under these circumstances, the Company remits back to the distributor a portion of their original purchase price after the resale transaction is completed in the form of a credit against the distributors' outstanding accounts receivable balance.  The credits are on a per unit basis and are not given to the distributor until they provide information regarding the sale to their end customer.  The price reductions vary significantly based on the customer, product, quantity ordered, geographic location and other factors and discounts to a price less than the Company's cost have historically been rare.  The effect of granting these credits establishes the net selling price from the Company to its distributors for the product and results in the net revenue recognized by the Company when the product is sold by the distributors to their end customers.  Thus, a portion of the "deferred income on shipments to distributors" balance represents the amount of distributors' original purchase price that will be credited back to the distributor in the future.  The wide range and variability of negotiated price concessions granted to distributors does not allow the Company to accurately estimate the portion of the balance in the deferred income on shipments to distributors account that will be credited back to the distributors.  Therefore, the Company does not reduce deferred income

on shipments to distributors or accounts receivable by anticipated future price concessions; rather, price concessions are recorded against deferred income on shipments to distributors when incurred, which is generally at the time the distributor sells the product.

At March 31, 2014, the Company had approximately $222.8 million of deferred revenue and $75.0 million in deferred cost of sales recognized as $147.8 million of deferred income on shipments to distributors.  At March 31, 2013, the Company had approximately $201.8 million of deferred revenue and $62.8 million of deferred cost of sales recognized as $139.0 million of deferred income on shipments to distributors.  The deferred income on shipments to distributors that will ultimately be recognized in the Company's income statement will be lower than the amount reflected on the balance sheet due to price credits to be granted to the distributors when the product is sold to their customers.  These price credits historically have resulted in the deferred income approximating the overall gross margins that the Company recognizes in the distribution channel of its business.

The Company reduces product pricing through price protection based on market conditions, competitive considerations and other factors.  Price protection is granted to distributors on the inventory they have on hand at the date the price protection is offered.  When the Company reduces the price of its products, it allows the distributor to claim a credit against its outstanding accounts receivable balances based on the new price of the inventory it has on hand as of the date of the price reduction.  There is no immediate revenue impact from the price protection, as it is reflected as a reduction of the deferred income on shipments to distributors' balance.

Products returned by distributors and subsequently scrapped have historically been immaterial to the Company's consolidated results of operations.  The Company routinely evaluates the risk of impairment of the deferred cost of sales component of the deferred income on shipments to distributors' account.  Because of the historically immaterial amounts of inventory that have been scrapped, and historically rare instances where discounts given to a distributor result in a price less than the Company's cost, the Company believes the deferred costs have a low risk of material impairment.

For license and other arrangements for SuperFlash^® technology that the Company is continuing to enhance and refine or under which it is obligated to provide unspecified enhancements, non-royalty revenue is recognized over the lesser of (1) the estimated period that the Company has historically enhanced and developed refinements to the specific technology, typically one to three years (the "upgrade period"), and (2) the remaining portion of the upgrade period after the date of delivery of all specified technology and documentation, provided that the fee is fixed or determinable and collection of the fee is reasonably assured.  Royalties received during the upgrade period are recognized as revenue based on an amortization calculation of the elapsed portion of the upgrade period compared to the entire estimated upgrade period.  Royalties received after the upgrade period has elapsed are recognized when reported to the Company, which generally coincides with the receipt of payment.  For licenses or other technology arrangements without an upgrade period, non-royalty revenue from license is recognized upon delivery of the technology if the fee is fixed or determinable and collection of the fee is reasonably assured.  Royalties are recognized when reported to the Company, which generally coincides with the receipt of payment.

Shipping charges billed to customers are included in net sales, and the related shipping costs are included in cost of sales. The Company collects and remits certain sales related taxes on sales of inventory and reports such amounts under the net method in its consolidated statements of income.

Product warranty

Product Warranty

The Company typically warrants its products against defects in materials and workmanship and non-conformance to specifications for 12 to 24 months.  The majority of the Company's product warranty claims are settled through the return of the defective product and the shipment of replacement product.  Warranty returns are included within the Company's allowance for returns, which is based on historical return rates.  Actual future returns could differ from the allowance established.  In addition, the Company accrues a liability for specific warranty costs expected to be settled other than through product return and replacement, if a loss is probable and can be reasonably estimated.  Product warranty expenses during fiscal 2014, 2013, and 2012 were immaterial.

Advertising cost

Advertising Costs

The Company expenses all advertising costs as incurred.  Advertising costs were immaterial for the fiscal years ended March 31, 2014, 2013 and 2012.

Research and development

Research and Development

Research and development costs are expensed as incurred.  Assets purchased to support the Company's ongoing research and development activities are capitalized when related to products which have achieved technological feasibility or that have alternative future uses and are amortized over their estimated useful lives.  Research and development expenses include expenditures for labor, share-based payments, depreciation, masks, prototype wafers, and expenses for development of process technologies, new packages, and software to support new products and design environments.

Foreign currency translation and forward contracts

Foreign Currency Translation and Forward Contracts

The Company's foreign subsidiaries are considered to be extensions of the U.S. Company and any translation gains and losses related to these subsidiaries are included in other income (expense) in the consolidated statements of income.  As the U.S. dollar is utilized as the functional currency, gains and losses resulting from foreign currency transactions (transactions denominated in a currency other than the subsidiaries' functional currency) are also included in income.  For a portion of fiscal 2013, certain foreign subsidiaries acquired as part of the SMSC acquisition had the local currency as the functional currency. Once these entities were integrated into the Company's legal structure and intercompany agreements were executed, the U.S. dollar became the functional currency. Gains and losses associated with currency rate changes on forward contracts are recorded currently in income.  These gains and losses have been immaterial to the Company's financial statements.

Income taxes

Income Taxes

As part of the process of preparing its consolidated financial statements, the Company is required to estimate its income taxes in each of the jurisdictions in which it operates.  This process involves estimating the Company's actual current tax exposure together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes.  These differences result in deferred tax assets and liabilities, which are included within the Company's consolidated balance sheet.  The Company must then assess the likelihood that its deferred tax assets will be recovered from future taxable income and to the extent it believes that recovery is not likely, it must establish a valuation allowance.  The Company has provided valuation allowances for certain of its deferred tax assets where it is more likely than not that some portion, or all of such assets, will not be realized.  

Cash and cash equivalents

Cash and Cash Equivalents

All highly liquid investments, including marketable securities purchased with a remaining maturity of three months or less when acquired are considered to be cash equivalents.

Investments

Investments – Available-for-Sale and Trading Securities

The Company classifies its investments in debt and marketable equity securities as available-for-sale or trading securities based upon management's intent with regard to the investments and the nature of the underlying securities. 

The Company's available-for-sale investments consist of government agency bonds, municipal bonds, auction rate securities (ARS), corporate bonds and marketable equity securities.  The Company's investments are carried at fair value with unrealized gains and losses reported in stockholders' equity unless losses are considered to be other than temporary impairments in which case the losses are recognized through the statement of income.  Premiums and discounts are amortized or accreted over the life of the related available-for-sale security.  Dividend and interest income are recognized when earned.  The cost of securities sold is calculated using the specific identification method. 

The Company includes within short-term investments its trading securities, as well as its income yielding available-for-sale securities that can be readily converted to cash and includes within long-term investments those income yielding available-for-sale securities with maturities of over one year that have unrealized losses attributable to them or those that cannot be readily liquidated.  Except as discussed in Note 5, the Company intends and has the ability to hold its long-term investments with temporary impairments until such time as these assets are no longer impaired.  Such recovery of unrealized losses is not expected to occur within the next year.

Non-Marketable Equity Investments

The Company's non-marketable equity investments are recorded using adjusted cost basis or the equity method of accounting, depending on the circumstances of each investment.  The Company's non-marketable equity investments are classified within other assets on the Company's consolidated balance sheet.  The Company's non-marketable equity investments include:

Equity Method Investments:  when the Company has the ability to exercise significant influence, but not control, over the investee, it records equity method gain or loss as "gain or loss from equity investments."  Equity method adjustments include the Company's proportionate share of the investee's income or loss.

Cost Method Investments:  when the Company does not have the ability to exercise significant influence over the investee, it records such investments at cost.

The Company reviews its investments quarterly for indicators of impairment.  The impairment review requires significant judgment and includes quantitative and qualitative analysis of identified events or circumstances that impact the fair value of the investment, such as:

• the investee's revenue and trends in earnings or losses relative to pre-defined milestones and overall business prospects;

• the technological feasibility of the investee's products and technologies;

• the general market conditions in the investee's industry or geographic area, including adverse regulatory or economic changes;

• factors related to the investee's ability to remain in business, such as the investee's liquidity, debt ratios, and the rate at which the investee is using its cash; and

• the investee's receipt of additional funding at a lower valuation.

If the fair value of an investment is below the Company's carrying value, the Company determines if the investment is other-than-temporarily impaired based on a quantitative and qualitative analysis, which includes assessing the severity and duration of the impairment and the likelihood of recovery before disposal.  If the investment is considered to be other-than-temporarily impaired, the Company writes down the investment to its fair value.  

Allowance for doubtful accounts

Allowance for Doubtful Accounts

The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments, which is included in bad debt expense.  The Company determines the adequacy of this allowance by regularly reviewing the composition of its accounts receivable aging and evaluating individual customer receivables, considering such customer's financial condition, credit history and current economic conditions.

Inventories

Inventories

Inventories are valued at the lower of cost or market using the first-in, first-out method.  The Company writes down its inventory for estimated obsolescence or unmarketable inventory in an amount equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions.  If actual market conditions are less favorable than those projected by the Company, additional inventory write-downs may be required.  Inventory impairment charges establish a new cost basis for inventory and charges are not subsequently reversed to income even if circumstances later suggest that increased carrying amounts are recoverable.  In estimating reserves for obsolescence, the Company primarily evaluates estimates of demand over a 12-month period and provides reserves for inventory on hand in excess of the estimated 12-month demand. Estimates for projected 12-month demand are generally based on the average shipments of the prior three-month period, which are then annualized to adjust for any potential seasonality in the Company's business. The estimated 12-month demand is compared to its most recently developed sales forecast to further reconcile the 12-month demand estimate. Management reviews and adjusts the estimates as appropriate based on specific situations. For example, demand can be adjusted up for new products for which historic sales are not representative of future demand. Alternatively, demand can be adjusted down to the extent any existing products are being replaced or discontinued.

In periods where the Company's production levels are substantially below normal operating capacity, unabsorbed overhead production costs associated with the reduced production levels of the Company's manufacturing facilities are charged directly to cost of sales.

Property, plant and equipment are stated at cost.  Major renewals and improvements are capitalized, while maintenance and repairs are expensed when incurred.  The Company's property and equipment accounting policies incorporate estimates, assumptions and judgments relative to the useful lives of its property and equipment.  Depreciation is provided for assets placed in service on a straight-line basis over the estimated useful lives of the relative assets, which range from 10 to 30 years for buildings and building improvements and 3 to 8 years for machinery and equipment.  The Company evaluates the carrying value of its property and equipment when events or changes in circumstances indicate that the carrying value of such assets may be impaired.  Asset impairment evaluations are, by nature, highly subjective.

Junior subordinated convertible debentures

Junior Subordinated Convertible Debentures

The Company separately accounts for the liability and equity components of its junior subordinated convertible debentures in a manner that reflects its nonconvertible debt (unsecured debt) borrowing rate when interest cost is recognized.  This results in a bifurcation of a component of the debt, classification of that component in equity and the accretion of the resulting discount on the debt to be recognized as part of interest expense in its consolidated statements of income.  Lastly, the Company includes the dilutive effect of the shares of its common stock issuable upon conversion of the outstanding junior subordinated convertible debentures in its diluted income per share calculation regardless of whether the market price trigger or other contingent conversion feature has been met.  The Company applies the treasury stock method as it has the intent and ability to settle the principal amount of the junior subordinated convertible debentures in cash.  This method results in incremental dilutive shares when the average market value of the Company's common stock for a reporting period exceeds the conversion price per share which was $25.87 at March 31, 2014 and adjusts as dividends are recorded in the future.

Litigation

Litigation

The Company's estimated range of liability related to pending litigation is based on claims for which management believes a loss is probable and it can estimate the amount or range of loss.  Because of the uncertainties related to both the outcome and range of any potential losses on the pending litigation, the Company is generally unable to make a reasonable estimate of the liability that could result from an unfavorable outcome.  As additional information becomes available, the Company will assess the potential liability related to its pending litigation and revise its estimates, if necessary.

Business combinations

Business Combinations

All of the Company's business combinations are accounted for at fair value under the acquisition method of accounting.  Under the acquisition method of accounting, (i) acquisition-related costs, except for those costs incurred to issue debt or equity securities, will be expensed in the period incurred; (ii) non-controlling interests will be valued at fair value at the acquisition date; (iii) in-process research and development will be recorded at fair value as an intangible asset at the acquisition date and amortized once the technology reaches technological feasibility; (iv) restructuring costs associated with a business combination will be expensed subsequent to the acquisition date; and (v) changes in deferred tax asset valuation allowances and income tax uncertainties after the acquisition date will be recognized through income tax expense or directly in contributed capital.  The measurement of fair value of assets acquired and liabilities assumed requires significant judgment.  The valuation of intangible assets and acquired investments, in particular, requires that the Company use valuation techniques such as the income approach.  The income approach includes the use of a discounted cash flow model, which includes discounted cash flow scenarios and requires the following significant estimates:  revenue, expenses, capital spending and other costs, and discount rates based on the respective risks of the cash flows.  The valuation of non-marketable equity investments acquired also takes into account variables such as conditions reflected in the capital markets, recent financing activity by the investees, the investees' capital structure and the terms of the investees' issued interests.

Goodwill and other intangible assets

Goodwill and Other Intangible Assets

Goodwill is recorded when the purchase price paid for an acquisition exceeds the estimated fair value of the net identified tangible and intangible assets acquired.  The Company is required to perform an annual impairment review, and more frequently under certain circumstances.  The goodwill is subjected to this test during the fourth quarter of the Company's fiscal year.  The Company engages primarily in the development, manufacture and sale of semiconductor products as well as technology licensing.  As a result, the Company concluded there are two reporting units, semiconductor products and technology licensing. Under the qualitative goodwill impairment assessment standard, management evaluates whether it is more likely than not that goodwill is impaired. If it is determined that it is more likely than not, the Company proceeds with the next step of the impairment test, which compares the fair value of the reporting unit to its carrying value.  If the Company determines through the impairment process that goodwill has been impaired, the Company will record the impairment charge in its results of operation.  Through March 31, 2014, the Company has not had impaired goodwill.  The Company's other intangible assets represent existing technologies, core and developed technology, in-process research and development, trademarks and trade names, and customer-related intangibles. Other intangible assets are amortized over their respective estimated lives, ranging from one year to ten years.  In the event that facts and circumstances indicate intangibles or other long-lived assets may be impaired, the Company evaluates the recoverability and estimated useful lives of such assets.  In-process research and development is capitalized until such time the related projects are completed or abandoned at which time the capitalized amounts will begin to be amortized or written off.

Impairment of long-lived assets

Impairment of Long-Lived Assets

The Company assesses whether indicators of impairment of long-lived assets are present.  If such indicators are present, the Company determines whether the sum of the estimated undiscounted cash flows attributable to the assets in question is less than their carrying value.  If less, the Company recognizes an impairment loss based on the excess of the carrying amount of the assets over their respective fair values.  Fair value is determined by discounted future cash flows, appraisals or other methods.  If the assets determined to be impaired are to be held and used, the Company recognizes an impairment loss through a charge to operating results to the extent the present value of anticipated net cash flows attributable to the asset are less than the asset's carrying value.  The Company would depreciate the remaining value over the remaining estimated useful life of the asset.

Share-based compensation

Share-Based Compensation

The Company has equity incentive plans under which non-qualified stock options and restricted stock units (RSUs) have been granted to employees and non-employee members of the Board of Directors.  In the second half of fiscal 2006, the Company adopted RSUs as its primary equity incentive compensation instrument for employees.  The Company also has an employee stock purchase plan for all eligible employees.

The Company estimates the fair value of share-based payment awards on the date of grant using an option pricing model.  The value of the portion of the award that is ultimately expected to vest is recognized as expense ratably over the requisite service periods.  The Company has estimated the fair value of each award as of the date of grant using the Black-Scholes option pricing model, which was developed for use in estimating the value of traded options that have no vesting restrictions and that are freely transferable.  

Determining the appropriate fair-value model and calculating the fair value of share-based awards at the date of grant requires judgment.  The fair value of RSUs is based on the fair market value of the Company's common stock on the date of grant discounted for expected future dividends.  The Company uses the Black-Scholes option pricing model to estimate the fair value of employee stock options and rights to purchase shares under stock participation plans.  Option pricing models, including the Black-Scholes model, also require the use of input assumptions, including expected volatility, expected life, expected dividend rate, and expected risk-free rate of return.  The Company uses a blend of historical and implied volatility based on options freely traded in the open market as it believes this is more reflective of market conditions and a better indicator of expected volatility than using purely historical volatility.  The expected life of the awards is based on historical and other economic data trended into the future.  The risk-free interest rate assumption is based on observed interest rates appropriate for the expected terms of the Company's awards.  The dividend yield assumption is based on the Company's history and expectation of future dividend payouts.  The Company estimates the number of share-based awards which will be forfeited due to employee turnover.  Quarterly changes in the estimated forfeiture rate would affect share-based compensation, as the impact on prior period amortization for all unvested awards is recognized in the period the forfeiture estimate is changed.  If the actual forfeiture rate is higher than the estimated forfeiture rate, then an adjustment is made to increase the estimated forfeiture rate, which will result in a decrease to the expense recognized in the financial statements.  If the actual forfeiture rate is lower than the estimated forfeiture rate, then an adjustment is made to decrease the estimated forfeiture rate, which will result in an increase to the expense recognized in the financial statements.  If forfeiture adjustments are made, they would affect the Company's results of operations.  The effect of forfeiture adjustments in the years ended March 31, 2014, 2013 and 2012 was immaterial.

The Company evaluates the assumptions used to value its awards on a quarterly basis.  If factors change and the Company employs different assumptions, share-based compensation expense may differ significantly from what was recorded in the past.  If there are any modifications or cancellations of the underlying unvested securities, the Company may be required to accelerate or increase any remaining unearned share-based compensation expense.  Future share-based compensation expense and unearned share-based compensation will increase to the extent that the Company grants additional equity awards to employees or it assumes unvested equity awards in connection with acquisitions.

Concentration of credit risk

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of investments in debt securities and trade receivables.  Investments in debt securities with original maturities of greater than six months consist primarily of AAA and AA rated financial instruments and counterparties.  The Company's investments are primarily in direct obligations of the U.S. government or its agencies, corporate bonds, and municipal bonds.

Concentrations of credit risk with respect to accounts receivable are generally not significant due to the diversity of the Company's customers and geographic sales areas.  The Company sells its products primarily to OEMs and distributors in the Americas, Europe and Asia.  The Company performs ongoing credit evaluations of its customers' financial condition and, as deemed necessary, may require collateral, primarily letters of credit.

Distributor advances, included in deferred income on shipments to distributors in the consolidated balance sheets, totaled $92.8 million at March 31, 2014 and $70.1 million at March 31, 2013.  On sales to distributors, the Company's payment terms generally require the distributor to settle amounts owed to the Company for an amount in excess of their ultimate cost.  The Company's sales price to its distributors may be higher than the amount that the distributors will ultimately owe the Company because distributors often negotiate price reductions after purchasing the product from the Company and such reductions are often significant.  It is the Company's practice to apply these negotiated price discounts to future purchases, requiring the distributor to settle receivable balances, on a current basis, generally within 30 days, for amounts originally invoiced.  This practice has an adverse impact on the working capital of the Company's distributors.  As such, the Company has entered into agreements with certain distributors whereby it advances cash to the distributors to reduce the distributor's working capital requirements.  These advances are reconciled at least on a quarterly basis and are estimated based on the amount of ending inventory as reported by the distributor multiplied by a negotiated percentage.  Such advances have no impact on revenue recognition or the Company's consolidated statements of income.  The Company processes discounts taken by distributors against its deferred income on shipments to distributors' balance and trues-up the advanced amounts generally after the end of each completed fiscal quarter.  The terms of these advances are set forth in binding legal agreements and are unsecured, bear no interest on unsettled balances and are due upon demand.  The agreements governing these advances can be canceled by the Company at any time.

Use of estimates

Use of Estimates

The Company has made a number of estimates and assumptions relating to the reporting of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities to prepare its consolidated financial statements in conformity with U.S. Generally Accepted Accounting Principles.  Actual results could differ from those estimates.

Recently Issued Accounting Pronouncements

Recently Issued Accounting Pronouncements

In May of 2014 the FASB issued Accounting Standard Update 2014-09-Revenue from Contracts with Customers, which will supersede nearly all existing revenue recognition guidance under US GAAP.  The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The Company is carefully evaluating its existing revenue recognition policies to determine whether any contracts in the scope of the guidance will be affected by the new requirements.  The effects may include identifying performance obligations in existing arrangements, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation.  The new standard is effective beginning the first quarter of the Company’s 2018 fiscal year.  Early adoption is not permitted.  The standard allows for either “full retrospective” adoption, meaning the standard is applied to all of the periods presented, or “modified retrospective” adoption, meaning the standard is applied only to the most current period presented in the financial statements.  The Company is currently evaluating the transition method that will be elected.

In the first quarter of fiscal 2014, the Company adopted the provisions of Accounting Standard Update 2013-02 Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which required the disclosure of amounts reclassified out of accumulated other comprehensive income (AOCI) to net income. The adoption of this provision did not have a material impact on the Company's consolidated financial statements and related disclosures.

Net income effect of share-based compensation	$	48,065		$	48,977		$	33,400

⁽¹⁾ During the year ended March 31, 2014, $7.4 million of share-based compensation expense was capitalized to inventory, and $7.3 million of previously capitalized share-based compensation expenses in inventory was sold.  During the year ended March 31, 2013, $5.9 million of share-based compensation expense was capitalized to inventory, and $8.2 million of previously capitalized share-based compensation expense in inventory was sold. During the year ended March 31, 2012, $6.6 million of share-based compensation expense was capitalized to inventory, and $5.6 million of previously capitalized share-based compensation expense in inventory was sold.

The amount of unearned share-based compensation currently estimated to be expensed in the remainder of fiscal 2015 through fiscal 2019 related to unvested share-based payment awards at March 31, 2014 is $83.5 million.  The weighted average period over which the unearned share-based compensation is expected to be recognized is approximately 2.01 years.

SMSC Acquisition-related Equity Awards

In connection with the acquisition of SMSC in fiscal 2013, the Company recognized $7.8 million in share-based compensation expense due to the accelerated vesting of outstanding equity awards upon termination of certain SMSC executive officers. Also, in connection with the acquisition of SMSC, the Company assumed certain unvested stock options, stock appreciation rights (SARs) and RSUs granted by SMSC. The assumed awards were measured at the acquisition date based on the estimated fair value, which was a total of $28.2 million. The Hull White II lattice model was used to value the assumed awards. A portion of that fair value, $6.9 million, which represented the preacquisition vested service provided by employees to SMSC, was included in the total consideration transferred as part of the acquisition. As of the acquisition date, the remaining portion of the fair value of those awards was $21.3 million, representing post-acquisition stock-based compensation expense that would be recognized as these employees provide service over the remaining vesting periods.

Segment Reporting [Abstract]

Segment Reporting Disclosure [Text Block]

GEOGRAPHIC AND SEGMENT INFORMATION

The Company's reporting segments include semiconductor products and technology licensing.  The Company does not allocate operating expenses, interest income, interest expense, other income or expense, or provision for or benefit from income taxes to these segments for internal reporting purposes, as the Company does not believe that allocating these expenses is beneficial in evaluating segment performance.  Additionally, the Company does not allocate assets to segments for internal reporting purposes as it does not manage its segments by such metrics.

The following table represents revenues and gross profit for each segment (amounts in thousands):

	Years ended March 31,
	2014				2013				2012
	Net Sales		Gross Profit		Net Sales		Gross Profit		Net Sales		Gross Profit
Semiconductor products	$	1,836,639	$	1,034,165	$	1,497,820	$	754,656	$	1,296,175	$	712,798

The Company sells its products to distributors and original equipment manufacturers (OEMs) in a broad range of market segments, performs on-going credit evaluations of its customers and, as deemed necessary, may require collateral, primarily letters of credit.  The Company's operations outside the U.S. consist of product assembly and final test facilities in Thailand, and sales and support centers and design centers in certain foreign countries.  Domestic operations are responsible for the design, development and wafer fabrication of products, as well as the coordination of production planning and shipping to meet worldwide customer commitments.  The Company's Thailand assembly and test facility is reimbursed in relation to value added with respect to assembly and test operations and other functions performed, and certain foreign sales offices receive compensation for sales within their territory.  Accordingly, for financial statement purposes, it is not meaningful to segregate sales or operating profits for the assembly and test and foreign sales office operations.  Identifiable long-lived assets (consisting of property, plant and equipment net of accumulated amortization) by geographic area are as follows (amounts in thousands):

	March 31,
	2014		2013
United States	$	311,926	$	325,326
Thailand	179,139		171,100
Various other countries	40,902		18,118
Total long-lived assets	$	531,967	$	514,544

Sales to unaffiliated customers located outside the U.S., primarily in Asia and Europe, aggregated approximately 84%, 83% and 82% of consolidated net sales for fiscal 2014, 2013 and 2012, respectively.  Sales to customers in Europe represented 21%, 22% and 23% of consolidated net sales for fiscal 2014, 2013 and 2012, respectively.  Sales to customers in Asia represented 60%, 58% and 56% of consolidated net sales for fiscal 2014, 2013 and 2012, respectively.  Within Asia, sales into China, including Hong Kong, represented 29%, 27% and 24% of consolidated net sales for fiscal 2014, 2013 and 2012, respectively.  Sales into Taiwan represented 13% of consolidated net sales in each of fiscal 2014 and 2013. Sales into Taiwan represented 15% of consolidated net sales for fiscal 2012.  Sales into any other individual foreign country did not exceed 10% of the Company's net sales for any of the years presented.

No single end customer accounted for 10% or more of the Company's net sales during fiscal 2014, 2013 or 2012. Future Electronics, one of the Company's distributors, accounted for approximately 10% of the Company's net sales in fiscal 2012. These net sales are reported in the semiconductor products segment. No other distributor accounted for 10% or more of the Company's net sales in fiscal 2014 or fiscal 2013.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

DERIVATIVE INSTRUMENTS

The Company has international operations and is thus subject to foreign currency rate fluctuations.  To help manage the risk of changes in foreign currency rates, the Company periodically enters into derivative contracts comprised of foreign currency forward contracts to hedge its asset and liability foreign currency exposure and a portion of its foreign currency operating expenses.  Approximately 99% of the Company's sales are U.S. Dollar denominated.  To date, the exposure related to foreign exchange rate volatility has not been material to the Company's operating results.  As of March 31, 2014, the Company had no foreign currency forward contracts outstanding. As of March 31, 2013, the Company had a foreign currency forward contract outstanding with a notional amount of $6.0 million to economically hedge certain balance sheet exposures related to the Japanese yen. The fair value of this contract was immaterial as of March 31, 2013. The Company recognized an immaterial amount of net realized gains and losses on foreign currency forward contracts in the years ended March 31, 2014, 2013 and 2012. Gains and losses from changes in the fair value of these foreign currency forward contracts are credited or charged to Other Income (Expense). The Company does not apply hedge accounting to its foreign currency derivative instruments.

NET INCOME PER COMMON SHARE

The following table sets forth the computation of basic and diluted net income per common share (in thousands, except per share amounts):

	Year ended March 31,
	2014		2013		2012
Net income	$	395,281	$	127,389	$	336,705
Weighted average common shares outstanding	198,291		194,595		191,283
Dilutive effect of stock options and RSUs	3,910		3,650		4,207
Dilutive effect of convertible debt	15,429		7,531		8,029
Weighted average common and potential common shares outstanding	217,630		205,776		203,519
Basic net income per common share	$	1.99	$	0.65	$	1.76
Diluted net income per common share	$	1.82	$	0.62	$	1.65

Diluted net income per common share for fiscal 2014, 2013, and 2012 includes 15,429,003, 7,531,111 and 8,029,255 shares, respectively, issuable upon the exchange of debentures (see Note 14).  The debentures have no impact on diluted net income per common share unless the average price of the Company's common stock exceeds the conversion price because the principal amount of the debentures will be settled in cash upon conversion.  Prior to conversion, the Company will include, in the diluted net income per common share calculation, the effect of the additional shares that may be issued when the Company's common stock price exceeds the conversion price using the treasury stock method.  The weighted average conversion price per share used in calculating the dilutive effect of the convertible debt for fiscal 2014, 2013 and 2012 was $26.32, $27.36 and $28.50, respectively. 

Weighted average common shares exclude the effect of option shares which are not dilutive.  There were no antidilutive option shares for fiscal 2014. For fiscal 2013 and 2012, the number of option shares that were antidilutive was 98,068 and 53,374, respectively.

Income Tax Disclosure [Abstract]

Income Taxes

INCOME TAXES

The Company is subject to income taxes in the U.S. and numerous foreign jurisdictions.  The Company files U.S. federal, U.S. state, and foreign income tax returns.  For U.S. federal, and in general for U.S. state tax returns, the fiscal 2011 and later tax years remain open for examination by tax authorities.  The U.S. Internal Revenue Service (IRS) is currently auditing Microchip and SMSC's 2011 and 2012 tax years.  For foreign tax returns, the Company is generally no longer subject to income tax examinations for years prior to fiscal 2006.

Significant judgment is required in evaluating the Company's uncertain tax positions and determining its provision for income taxes.  Although the Company believes that it has appropriately reserved for its uncertain tax positions, no assurance can be given that the final tax outcome of these matters will not be different than expectations.  The Company will adjust these reserves in light of changing facts and circumstances, such as the closing of a tax audit, the refinement of an estimate, the closing of a statutory audit period or changes in applicable tax law.  To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will impact the provision for income taxes in the period in which such determination is made.  The provision for income taxes includes the impact of reserve provisions and changes to the reserves that are considered appropriate, as well as related net interest.

The Company recognizes liabilities for anticipated tax audit issues in the U.S. and other domestic and international tax jurisdictions based on its estimate of whether, and the extent to which, additional tax payments are more likely than not.  The Company believes that it has appropriate support for the income tax positions taken and to be taken on its tax returns and that its accruals for tax liabilities are adequate for all open years based on an assessment of many factors including past experience and interpretations of tax law applied to the facts of each matter.  

The Company believes it maintains appropriate reserves to offset any potential income tax liabilities that may arise upon final resolution of matters for open tax years. If such reserve amounts ultimately prove to be unnecessary, the resulting reversal of such reserves would result in tax benefits being recorded in the period the reserves are no longer deemed necessary.  If such amounts prove to be less than an ultimate assessment, a future charge to expense would be recorded in the period in which the assessment is determined.  Although the timing of the resolution and/or closure of audits is highly uncertain, the Company does not believe that it is reasonably possible that the unrecognized tax benefits would materially change in the next 12 months.

The following table summarizes the activity related to the Company's gross unrecognized tax benefits from April 1, 2011 to March 31, 2014 (amounts in thousands):

As of March 31, 2014, the Company had accrued approximately $0.3 million related to the potential payment of interest on the Company's uncertain tax positions.  As of March 31, 2013, the Company had accrued approximately $3.2 million related to the potential payment of interest on the Company's uncertain tax positions. Interest was included in the provision for income taxes.  The Company has accrued for approximately $29.7 million and $30.6 million in penalties related to its uncertain tax positions related to its international locations as of March 31, 2014 and March 31, 2013, respectively.  Interest and penalties charged or (credited) to operations during the years ended March 31, 2014, 2013 and 2012 related to the Company's uncertain tax positions were $0.2 million, $0.8 million and $0.9 million, respectively.

The tax benefit associated with the Company's equity incentive plans reduced taxes currently payable by $1.4 million and $11.0 million for the years ended March 31, 2014 and 2012, respectively.  These amounts were credited to additional paid-in capital in each of these fiscal years. There was no tax benefit associated with the Company's equity incentive plans for the year ended March 31, 2013.

The provision for income taxes differs from the amount computed by applying the statutory federal tax rate to income before income taxes.  The sources and tax effects of the differences in the total income tax provision are as follows (amounts in thousands):

	Year Ended March 31,
	2014			2013			2012
Computed expected income tax provision	$	151,324		$	53,262		$	132,894

⁽¹⁾ The release of prior year tax positions during fiscal 2014 increased each of the current year basic and diluted net income per common share by $0.07. The release of prior year tax positions during fiscal 2013 increased the current year basic and diluted net income per common share by $0.04 and $0.03, respectively. The release of prior year tax positions during fiscal 2012 increased each of the current year basic and diluted net income per common share by $0.01.

Pretax income from foreign operations was $404.1 million, $234.3 million and $328.5 million for the years ended March 31, 2014, 2013 and 2012, respectively.  Unremitted foreign earnings that are considered to be permanently invested outside the U.S., and on which no deferred taxes have been provided, amounted to approximately $2.4 billion at March 31, 2014.  The Company has the ability and intent to indefinitely reinvest its foreign earnings.  Should the Company elect in the future to repatriate a portion of the foreign earnings so invested, the Company would incur income tax expense on such repatriation, net of any available deductions and foreign tax credits.  This would result in additional income tax expense beyond the computed effective tax rate in such periods.

During the year ended March 31, 2014, the Company settled an IRS examination of fiscal years 2009 and 2010.  In addition, the Company benefited from the expiration of the statute of limitations and other releases related to previously accrued tax reserves.  The total tax benefit associated with these items resulted in a reduction of income tax provision of approximately $14.6 million and a decrease in the effective tax rate of 3.4%.

In January 2013, the U.S. Congress retroactively reinstated the research and development tax credit from January 1, 2012.  As a result, the Company recognized a one-time tax benefit of $8.1 million in the year ended March 31, 2013 related to the reinstatement of the credit for calendar year 2012.

The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities are as follows (amounts in thousands):

	March 31,
	2014			2013
Deferred tax assets:
Deferred intercompany profit	$	9,623		$	13,679

Net deferred tax liability	$	(307,826	)	$	(307,563	)

In addition to the deferred tax assets listed above, the Company has unrecorded tax benefits of $29.8 million attributable to the difference between the amount of the financial statement expense and the allowable tax deduction associated with share-based compensation. As a result of net operating loss (NOL) carryforwards, the Company was not able to recognize the excess tax benefits of share-based compensation deductions because the deductions did not reduce income tax payable. Although not recognized for financial reporting purposes, this unrecorded tax benefit is available to reduce future income and is incorporated into the disclosed amounts of the Company's federal and state NOL carryforwards, discussed below. If subsequently realized, the benefit will be recorded to contributed capital.

The Company had federal, state and foreign NOL carryforwards with an estimated tax effect of $110.6 million available at March 31, 2014.  The federal and state NOL carryforwards expire at various times between 2015 and 2034.  The Company believes that it is more likely than not that the benefit from certain foreign and state NOL carryforwards will not be realized.  In recognition of this risk, at March 31, 2014, the Company has provided a valuation allowance of $20.5 million.  The Company also has state tax credits with an estimated tax effect of $54.3 million available at March 31, 2014.  These state tax credits expire at various times between 2015 and 2034.  The Company believes that it is more likely than not that the full benefit from these state tax credits will not be realized, and therefore has provided a valuation allowance of $51.4 million.  The Company has U.S foreign tax credits with an estimated tax effect of $21.9 million that expire at various times between 2015 and 2024.  The Company believes it is more likely than not that the benefit from these credits will not be fully realized and has provided a valuation allowance of $21.8 million.  At March 31, 2014, the Company had credits for increasing research activity in the amount of $44.4 million that expire at various times between 2021 and 2034. In addition, the Company had $3.7 million of alternative minimum tax credits that do not expire. At March 31, 2014, the Company had alternative minimum tax NOL carryforwards of approximately $308.0 million that expire between 2032 and 2034.

The Company's Thailand manufacturing operations currently benefit from numerous tax holidays granted to the Company based on its investment in property, plant and equipment in Thailand.  The Company's tax holiday periods in Thailand expire at various times in the future, however, the Company actively seeks to acquire new tax holidays.  The Company does not expect the future expiration of any of its tax holiday periods in Thailand to have a material impact on its effective tax rate.  The aggregate dollar benefits derived from these tax holidays approximated $16.8 million, $12.0 million and $6.5 million in fiscal 2014, 2013 and 2012, respectively.  The benefit the tax holiday had on diluted net income per share approximated $0.08 in fiscal 2014, $0.06 in fiscal 2013 and $0.03 in fiscal 2012.

On September 13, 2013, the IRS and the Treasury Department released final regulations under Section 162(a) and 263(a) on the deduction and capitalization of expenditures related to tangible property. The new regulations apply to tax years beginning on or after January 1, 2014; therefore they had no material impact on fiscal 2014. The Company believes that no material impact will result from these new regulations (specifically given the Company’s NOL position), but the Company is in the process of evaluating the full impact of these changes.

Announcement of Signing of Definitive Agreement to Acquire ISSC

On May 22, 2014, the Company announced a definitive agreement to acquire ISSC Technologies Corporation (ISSC), a leading provider of low power Bluetooth and advanced wireless solutions for the Internet Of Things (IoT) market. ISSC is publicly traded on the GreTai Securities Market and is headquartered in Hsinchu, Taiwan with sales or research subsidiaries in Shenzhen, China and Torrance, California. Under the terms of the transaction, the Company will commence a tender offer through its indirect wholly owned Cayman Island subsidiary (the "Cayman Subsidiary") to acquire all of the outstanding shares of ISSC for approximately $4.74 per share ($143 New Taiwan (NT) dollars per share, based on an assumed exchange rate of NT$30.15 per U.S. dollar) in cash, and acquire any remaining shares pursuant to a follow-on merger at approximately $4.74 per share minus any dividends paid by ISSC prior to the close of the transaction. The transaction represents a total equity value of about $328.5 million (approximately NT$9.9 billion), and a total enterprise value of about $294.3 million (approximately NT$8.9 billion), after excluding ISSC’s cash and investments on its balance sheet of approximately $34.2 million (approximately NT$1.0 billion). Upon completion of the tender offer through the Cayman Subsidiary, the Company will own the majority of the outstanding shares of ISSC and will consolidate ISSC’s financial statements.

CREDIT FACILITY

On June 27, 2013, the Company entered into a $2.0 billion credit agreement among the Company, the lenders from time to time that are parties thereto and JPMorgan Chase Bank, N.A., as administrative agent (the Credit Agreement). The Credit Agreement provides for a $350 million term loan and a $1.65 billion revolving credit facility, with a $125 million foreign currency sublimit, a $35 million letter of credit sublimit and a $25 million swingline loan sublimit, terminating on June 27, 2018 (the Maturity Date). The Credit Agreement also contains an increase option permitting the Company, subject to certain requirements, to arrange with existing lenders and/or new lenders for them to provide up to an aggregate of $300 million in additional commitments, which may be for revolving loans or term loans. Proceeds of loans made under the Credit Agreement may be used for working capital and general corporate purposes. The Credit Agreement replaced another credit agreement the Company had in place since August 2011. At March 31, 2014, $650.0 million of borrowings were outstanding under the Credit Agreement consisting of $300 million of a revolving line of credit and $350 million of a term loan, net of $1.1 million of debt discount resulting from amounts paid to the lenders. The repayment schedule for the term loan portion of the Credit Agreement outstanding at March 31, 2014 is as follows (amounts in thousands):

Year Ending March 31,	Amount
2015	$	17,500
2016	17,500
2017	35,000
2018	35,000
2019	245,000
Total	$	350,000

The loans under the Credit Agreement bear interest, at the Company's option, at the base rate plus a spread of 0.25% to 1.25% or an adjusted LIBOR rate (based on one, two, three, or six-month interest periods) plus a spread of 1.25% to 2.25%, in each case with such spread being determined based on the consolidated leverage ratio for the preceding four fiscal quarter period. The base rate means the highest of JPMorgan Chase Bank, N.A.'s prime rate, the federal funds rate plus a margin equal to 0.50% and the adjusted LIBOR rate for a 1-month interest period plus a margin equal to 1.00%. Swingline loans accrue interest at a per annum rate based on the base rate plus the applicable margin for base rate loans. Base rate loans may only be made in U.S. Dollars. The Company is also obligated to pay other administration fees and letter of credit fees for a credit facility of this size and type.

Interest is due and payable in arrears quarterly for loans bearing interest at the base rate and at the end of an interest period (or at each three month interval in the case of loans with interest periods greater than three months) in the case of loans bearing interest at the adjusted LIBOR rate. Interest expense related to the Credit Agreement was approximately $14.6 million in fiscal 2014. Interest expense related to the Company's prior credit agreement was approximately $7.0 million in fiscal 2013 and approximately $3.3 million in fiscal 2012. Principal, together with all accrued and unpaid interest, is due and payable on the Maturity Date. The weighted average interest rate on short-term borrowings outstanding at March 31, 2014 related to the credit agreement was 1.65%. The Company also pays a quarterly commitment fee on the available but unused portion of its line of credit which is calculated on the average daily available balance during the period. The Company may prepay the loans and terminate the commitments, in whole or in part, at any time without premium or penalty, subject to certain conditions including minimum amounts in the case of commitment reductions and reimbursement of certain costs in the case of prepayments of LIBOR loans.

The Company's obligations under the Credit Agreement are guaranteed by certain of its subsidiaries meeting materiality thresholds set forth in the Credit Agreement. To secure the Company's obligations under the Credit Agreement, the Company and its domestic subsidiaries will be required to pledge the equity securities of certain of their respective material subsidiaries, subject to certain exceptions and limitations.

The Credit Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict the Company and its subsidiaries' ability to, among other things, incur subsidiary indebtedness, grant liens, merge or consolidate, dispose of assets, make investments, make acquisitions, enter into certain transactions with affiliates, pay dividends or make distributions, repurchase stock, enter into restrictive agreements and enter into sale and leaseback transactions, in each case subject to customary exceptions for a credit facility of this size and type. The Company is also required to maintain compliance with a consolidated leverage ratio and a consolidated interest coverage ratio. At March 31, 2014, the Company was in compliance with these covenants.

The Credit Agreement includes customary events of default that include, among other things, non-payment defaults, inaccuracy of representations and warranties, covenant defaults, cross default to material indebtedness, bankruptcy and insolvency defaults, material judgment defaults, ERISA defaults and a change of control default. The occurrence of an event of default could result in the acceleration of the obligations under the Credit Agreement. Under certain circumstances, a default interest rate will apply on all obligations during the existence of an event of default under the Credit Agreement at a per annum rate equal to 2.00% above the applicable interest rate for any overdue principal and 2.00% above the rate applicable for base rate loans for any other overdue amounts.

Reclassifications of Prior Periods [Text Block]

RECLASSIFICATION OF PRIOR PERIODS

In the quarter ended December 31, 2013, the Company identified an error to the presentation on its consolidated statements of cash flows of the amortization of premium of available-for-sale investments. The Company previously included the amortization of the premium as an investing activity. This amortization is a non-cash expense that should be recorded in the adjustments to reconcile net income to net cash provided by operating activities. The Company has corrected this error in the current period, and has conformed previous periods to the current presentation. Based on the Company's evaluation of relevant quantitative and qualitative factors, it determined that the classification errors are immaterial to the prior period financial statements and the Company plans to correct the comparative presentation of the prior periods in future filings. The effect on net cash provided by operating activities and net cash used in investing activities for the previous periods covered by this report are shown below (amounts in thousands):

BUSINESS ACQUISITIONS

On November 21, 2013, the Company completed an acquisition which was accounted for under the acquisition method of accounting. The Company had a prior 18.3% ownership interest in the acquired company accounted for as a cost method investment and recognized an approximate $2.4 million gain to write that ownership interest up to fair value in fiscal 2014. The total consideration paid for the remaining 81.7% equity of the business, net of cash acquired, was $9.0 million. The purchase price of the acquisition resulted in purchased intangible assets of $4.1 million and goodwill of approximately $6.4 million. The purchased intangible assets are being amortized over a weighted average period of approximately 8 years.

On August 2, 2012, the Company acquired SMSC, a publicly traded company based in Hauppauge, New York. The acquisition was accounted for under the acquisition method of accounting. The Company retained an independent third-party appraiser to assist management in its valuation. The table below represents the allocation of the purchase price, including adjustments to the purchase price allocation from the originally reported figures at March 31, 2013, to the net assets acquired based on their estimated fair values as of August 2, 2012. The purchase price allocation was finalized as of August 2, 2013. All adjustments shown in the table below were recorded during the three months ended June 30, 2013 (amounts in thousands):

On April 18, 2012, the Company acquired Roving Networks, a privately-held company. The acquisition was accounted for under the acquisition method of accounting.  Total consideration paid was approximately $20.6 million.  The acquisition also included contingent consideration with an estimated fair value at the date of purchase of approximately $14.7 million. During the year ended March 31, 2013, the fair value of the contingent consideration was increased to $19.1 million with the related expense of $4.4 million included in special charges. During the year ended March 31, 2014, the fair value of the contingent consideration was increased further to $20.5 million with the related expense of $1.4 million included in special charges. The contingent consideration was fully paid as of March 31, 2014. The purchase price of the acquisition resulted in purchased intangible assets of approximately $22.8 million and goodwill of approximately $8.7 million which was all allocated to the Company's semiconductor products segment.  Purchased intangible assets included $10.6 million of developed technology, $10.6 million of customer-related intangibles, $0.3 million of backlog and $1.3 million of in-process research and development. The purchased intangible assets (other than in-process technology and backlog) are being amortized over their expected useful lives which range between four and ten years. Backlog was amortized over one year and in-process research and development is capitalized until such time the related projects are completed or abandoned at which time the capitalized amounts will begin to be amortized or written off.

On February 9, 2012, the Company acquired Ident Technology AG, a privately-held semiconductor company. The acquisition was accounted for under the acquisition method of accounting.  Total consideration paid was approximately $39.5 million.  The purchase price of the acquisition resulted in purchased intangible assets of approximately $18.1 million, of which $8.2 million related to in-process technology, and goodwill of approximately $17.4 million which was all allocated to the Company's semiconductor products segment.  Goodwill recognized in this transaction is non-deductible.

2.125% Junior subordinated convertible debentures (Notes)

Convertible Debt [Abstract]

Junior subordinated convertible debentures

2.125% JUNIOR SUBORDINATED CONVERTIBLE DEBENTURES

The Company's $1.15 billion principal amount of 2.125% junior subordinated convertible debentures due December 15, 2037, are subordinated in right of payment to any future senior debt of the Company and are effectively subordinated in right of payment to the liabilities of the Company's subsidiaries.  The debentures are convertible, subject to certain conditions, into shares of the Company's common stock at an initial conversion rate of 29.2783 shares of common stock per $1,000 principal amount of debentures, representing an initial conversion price of approximately $34.16 per share of common stock.  As of March 31, 2014, the holders of the debentures have the right to convert their debentures between April 1, 2014 and June 30, 2014 because for at least 20 trading days during the 30 consecutive trading day period ending on March 31, 2014, the Company's common stock had a last reported sale price greater than 130% of the conversion price. As of March 31, 2014, a holder could realize more economic value by selling its debentures in the over the counter market than from converting its debentures.  As a result of cash dividends paid since the issuance of the debentures, the conversion rate has been adjusted to 38.6588 shares of common stock per $1,000 of principal amount of debentures, representing a conversion price of approximately $25.87 per share of common stock. The debentures include a contingent interest mechanism that begins in December 2017. The terms of the contingent interest include a 0.25% interest rate if the debentures are trading at less than $40 and 0.5% if the debentures are trading at greater than $150. Based on the current trading price of the debentures the contingent interest rate in calendar year 2017 would be 0.5%.

As the debentures can be settled in cash upon conversion, for accounting purposes, the debentures were bifurcated into a liability component and an equity component, which are both initially recorded at fair value.  The carrying value of the equity component at March 31, 2014 and at March 31, 2013 was $822.4 million.  The estimated fair value of the liability component of the debentures at the issuance date was $327.6 million, resulting in a debt discount of $822.4 million.  The unamortized debt discount was $777.2 million at March 31, 2014 and $786.2 million at March 31, 2013.  The carrying value of the debentures was $371.9 million at March 31, 2014 and $363.4 million at March 31, 2013.  The remaining period over which the unamortized debt discount will be recognized as non-cash interest expense is 23.75 years.  In the years ended March 31, 2014, 2013 and 2012 the Company recognized $9.0 million, $8.2 million and $7.5 million, respectively, in non-cash interest expense related to the amortization of the debt discount.  The Company recognized $24.4 million of interest expense related to the 2.125% coupon on the debentures in each of fiscal 2014, fiscal 2013 and fiscal 2012.

Fair Value Measurements (Notes)

Fair Value, Assets, Liabilities and Stockholders' Equity Measured on Recurring Basis [Abstract]

Fair Value Measurements

FAIR VALUE MEASUREMENTS

Accounting rules for fair value clarify that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.  As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability.  As a basis for considering such assumptions, the Company utilizes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1- Observable inputs such as quoted prices in active markets;

Level 2- Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and

Level 3- Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

Marketable Debt Instruments

Marketable debt instruments include instruments such as corporate bonds and debt, government agency bonds, bank deposits, municipal bonds, and money market fund deposits. When the Company uses observable market prices for identical securities that are traded in less active markets, the Company classifies its marketable debt instruments as Level 2. When observable market prices for identical securities are not available, the Company prices its marketable debt instruments using non-binding market consensus prices that are corroborated with observable market data; quoted market prices for similar instruments; or pricing models, such as a discounted cash flow model, with all significant inputs derived from or corroborated with observable market data. Non-binding market consensus prices are based on the proprietary valuation models of pricing providers or brokers. These valuation models incorporate a number of inputs, including non-binding and binding broker quotes; observable market prices for identical or similar securities; and the internal assumptions of pricing providers or brokers that use observable market inputs and, to a lesser degree, unobservable market inputs. The Company corroborates non-binding market consensus prices with observable market data using statistical models when observable market data exists. The discounted cash flow model uses observable market inputs, such as LIBOR-based yield curves, currency spot and forward rates, and credit ratings.

There were no transfers between Level 1 and Level 2 during fiscal 2014 or fiscal 2013.

At March 31, 2014, the Company's ARS for which auctions were unsuccessful are made up of securities related to the insurance industry valued at $9.8 million with a par value of $22.4 million. At March 31, 2013, the Company's ARS for which auctions were unsuccessful were made up of bonds related to the insurance industry valued at $9.8 million, securities related to the energy and telecommunications sectors valued at $5.3 million, and student loan securities valued at $18.7 million.

The Company estimated the fair value of its ARS, which are classified as Level 3 securities, based on the following: (i) the underlying structure of each security; (ii) the present value of future principal and interest payments discounted at rates considered to reflect current market conditions; (iii) consideration of the probabilities of default, auction failure, or repurchase at par for each period; and (iv) estimates of the recovery rates in the event of default for each security. The significant unobservable inputs used in the fair value measurement of the insurance sector ARS as of March 31, 2014 were estimated risk free discount rates, liquidity risk premium, and the liquidity horizon. The risk free discount rate applied to these securities was 2% to 2.5% adjusted for the liquidity risk premium which ranged from 9.1% to 29.5%. The anticipated liquidity horizon ranged from 7 to 10 years. A significant increase in the liquidity premium or discount rate, in isolation, would lead to a significantly lower fair value measurement. A significant increase in the liquidity horizon, in isolation, would lead to a significantly lower fair value measurement. Each quarter the Company investigates material changes in the fair value measurements of its ARS.

Level 3 liabilities at March 31, 2013 include contingent consideration from the Company's Roving Networks acquisition, which was fully paid as of March 31, 2014.

The following tables present a reconciliation for all assets and liabilities measured at fair value on a recurring basis, excluding accrued interest components, using significant unobservable inputs (Level 3) for the years ended March 31, 2014 and March 31, 2013 (amounts in thousands):

INVESTMENTS

The Company's investments are intended to establish a high-quality portfolio that preserves principal, meets liquidity needs, avoids inappropriate concentrations, and delivers an appropriate yield in relationship to the Company's investment guidelines and market conditions.  The following is a summary of available-for-sale securities at March 31, 2014 (amounts in thousands):

At March 31, 2014, the Company's available-for-sale debt securities are presented on the consolidated balance sheets as short-term investments of $878.2 million and long-term investments of $798.7 million.  At March 31, 2013, the Company’s available-for-sale debt securities and marketable equity securities are presented on the consolidated balance sheets as short-term investments of $1,050.3 million and long-term investments of $257.5 million.

At March 31, 2014, the Company evaluated its investment portfolio and noted unrealized losses of $4.0 million on its debt securities with an aggregated fair value of $782.7 million, which were due primarily to higher interest rates and resulting declines in market prices.  Management does not believe any of the unrealized losses represent an other-than-temporary impairment based on its evaluation of available evidence as of March 31, 2014 and the Company's intent is to hold these investments until these assets are no longer impaired, except for certain auction rate securities (ARS). For those debt securities not scheduled to mature until after March 31, 2015, such recovery is not anticipated to occur in the next year and these investments have been classified as long-term investments.

The amortized cost and estimated fair value of the available-for-sale securities at March 31, 2014, by contractual maturity, excluding corporate debt of $6.2 million, which has no contractual maturity, are shown below (amounts in thousands). Expected maturities can differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties, and the Company views its available-for-sale securities as available for current operations.

Fair Value of Financial Instruments (Notes)

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amount of cash equivalents approximates fair value because their maturity is less than three months. Management believes the carrying amount of the equity and cost-method investments materially approximated fair value at March 31, 2014 based upon unobservable inputs. The fair values of these investments have been determined as Level 3 fair value measurements. The fair values of the Company's line of credit and short-term and long-term borrowings are estimated using discounted cash flow analyses, based on the Company's current incremental borrowing rates for similar types of borrowing arrangements and approximate carrying value. Based on the borrowing rates currently available to the Company for bank loans with similar terms and average maturities, the fair value of the Company's line of credit and long-term borrowings at March 31, 2014 approximated book value and are considered Level 2 in the fair value hierarchy described in Note 6. The carrying amount of accounts receivable, accounts payable and accrued liabilities approximates fair value due to the short-term maturity of the amounts.  The fair value of the Company's junior subordinated convertible debentures was $2.138 billion at March 31, 2014 and $1.639 billion at March 31, 2013 based on observable market prices for these debentures, which are traded in less active markets and are therefore classified as a Level 2 fair value measurement.

Accounting Policies [Abstract]

Summary of significant accounting policies

SIGNIFICANT ACCOUNTING POLICIES

Nature of Business

Microchip develops, manufactures and sells specialized semiconductor products used by its customers for a wide variety of embedded control applications.  Microchip's product portfolio comprises 8-bit, 16-bit and 32-bit PIC^® microcontrollers and 16-bit dsPIC^® digital signal controllers, which feature on-board Flash (reprogrammable) memory technology.  In addition, Microchip offers a broad spectrum of high-performance linear, mixed-signal, power management, thermal management, RF, safety and security and interface devices, as well as serial EEPROMs, Serial Flash memories and Parallel Flash memories.  Microchip also licenses Flash-IP solutions that are incorporated in a broad range of products.

Principles of Consolidation

The consolidated financial statements include the accounts of Microchip Technology Incorporated and its wholly-owned subsidiaries (Microchip or the Company).  The Company does not have any subsidiaries in which it does not own 100% of the outstanding stock.  All of the Company's subsidiaries are included in the consolidated financial statements.  All significant intercompany accounts and transactions have been eliminated in consolidation.

Revenue Recognition

The Company recognizes revenue when the earnings process is complete, as evidenced by an agreement with the customer, transfer of title as well as fixed or determinable pricing and when collectability is reasonably assured.  The Company recognizes revenue from product sales to original equipment manufacturers (OEMs) upon shipment and records reserves for estimated customer returns.

Distributors worldwide generally have broad price protection and product return rights, so the Company defers revenue recognition until the distributor sells the product to their customer.  Revenue is recognized when the distributor sells the product to their end customer, at which time the sales price becomes fixed or determinable.  Revenue is not recognized upon the Company's shipment to the distributors since, due to discounts from list price as well as price protection rights, the sales price is not substantially fixed or determinable at that time.  At the time of shipment to these distributors, the Company records a trade receivable for the selling price as there is a legally enforceable right to payment, relieves inventory for the carrying value of goods shipped since legal title has passed to the distributor, and records the gross margin in deferred income on shipments to distributors on its consolidated balance sheets.

Deferred income on shipments to distributors effectively represents gross margin on the sale to the distributor at the initial shipment date; however, the amount of gross margin recognized by the Company in future periods will be less than the deferred margin as a result of credits granted to distributors on specifically identified products and customers to allow the distributors to earn a competitive gross margin on the sale of the Company's products to their end customers and price protection concessions related to market pricing conditions.

The Company sells the majority of the items in its product catalog to its distributors worldwide at a uniform list price.  However, distributors resell the Company's products to end customers at a very broad range of individually negotiated price points.  The majority of the Company's distributors' resales require a reduction from the original list price paid.  Often, under these circumstances, the Company remits back to the distributor a portion of their original purchase price after the resale transaction is completed in the form of a credit against the distributors' outstanding accounts receivable balance.  The credits are on a per unit basis and are not given to the distributor until they provide information regarding the sale to their end customer.  The price reductions vary significantly based on the customer, product, quantity ordered, geographic location and other factors and discounts to a price less than the Company's cost have historically been rare.  The effect of granting these credits establishes the net selling price from the Company to its distributors for the product and results in the net revenue recognized by the Company when the product is sold by the distributors to their end customers.  Thus, a portion of the "deferred income on shipments to distributors" balance represents the amount of distributors' original purchase price that will be credited back to the distributor in the future.  The wide range and variability of negotiated price concessions granted to distributors does not allow the Company to accurately estimate the portion of the balance in the deferred income on shipments to distributors account that will be credited back to the distributors.  Therefore, the Company does not reduce deferred income

on shipments to distributors or accounts receivable by anticipated future price concessions; rather, price concessions are recorded against deferred income on shipments to distributors when incurred, which is generally at the time the distributor sells the product.

At March 31, 2014, the Company had approximately $222.8 million of deferred revenue and $75.0 million in deferred cost of sales recognized as $147.8 million of deferred income on shipments to distributors.  At March 31, 2013, the Company had approximately $201.8 million of deferred revenue and $62.8 million of deferred cost of sales recognized as $139.0 million of deferred income on shipments to distributors.  The deferred income on shipments to distributors that will ultimately be recognized in the Company's income statement will be lower than the amount reflected on the balance sheet due to price credits to be granted to the distributors when the product is sold to their customers.  These price credits historically have resulted in the deferred income approximating the overall gross margins that the Company recognizes in the distribution channel of its business.

The Company reduces product pricing through price protection based on market conditions, competitive considerations and other factors.  Price protection is granted to distributors on the inventory they have on hand at the date the price protection is offered.  When the Company reduces the price of its products, it allows the distributor to claim a credit against its outstanding accounts receivable balances based on the new price of the inventory it has on hand as of the date of the price reduction.  There is no immediate revenue impact from the price protection, as it is reflected as a reduction of the deferred income on shipments to distributors' balance.

Products returned by distributors and subsequently scrapped have historically been immaterial to the Company's consolidated results of operations.  The Company routinely evaluates the risk of impairment of the deferred cost of sales component of the deferred income on shipments to distributors' account.  Because of the historically immaterial amounts of inventory that have been scrapped, and historically rare instances where discounts given to a distributor result in a price less than the Company's cost, the Company believes the deferred costs have a low risk of material impairment.

For license and other arrangements for SuperFlash^® technology that the Company is continuing to enhance and refine or under which it is obligated to provide unspecified enhancements, non-royalty revenue is recognized over the lesser of (1) the estimated period that the Company has historically enhanced and developed refinements to the specific technology, typically one to three years (the "upgrade period"), and (2) the remaining portion of the upgrade period after the date of delivery of all specified technology and documentation, provided that the fee is fixed or determinable and collection of the fee is reasonably assured.  Royalties received during the upgrade period are recognized as revenue based on an amortization calculation of the elapsed portion of the upgrade period compared to the entire estimated upgrade period.  Royalties received after the upgrade period has elapsed are recognized when reported to the Company, which generally coincides with the receipt of payment.  For licenses or other technology arrangements without an upgrade period, non-royalty revenue from license is recognized upon delivery of the technology if the fee is fixed or determinable and collection of the fee is reasonably assured.  Royalties are recognized when reported to the Company, which generally coincides with the receipt of payment.

Shipping charges billed to customers are included in net sales, and the related shipping costs are included in cost of sales. The Company collects and remits certain sales related taxes on sales of inventory and reports such amounts under the net method in its consolidated statements of income.

Product Warranty

The Company typically warrants its products against defects in materials and workmanship and non-conformance to specifications for 12 to 24 months.  The majority of the Company's product warranty claims are settled through the return of the defective product and the shipment of replacement product.  Warranty returns are included within the Company's allowance for returns, which is based on historical return rates.  Actual future returns could differ from the allowance established.  In addition, the Company accrues a liability for specific warranty costs expected to be settled other than through product return and replacement, if a loss is probable and can be reasonably estimated.  Product warranty expenses during fiscal 2014, 2013, and 2012 were immaterial.

Advertising Costs

The Company expenses all advertising costs as incurred.  Advertising costs were immaterial for the fiscal years ended March 31, 2014, 2013 and 2012.

Research and Development

Research and development costs are expensed as incurred.  Assets purchased to support the Company's ongoing research and development activities are capitalized when related to products which have achieved technological feasibility or that have alternative future uses and are amortized over their estimated useful lives.  Research and development expenses include expenditures for labor, share-based payments, depreciation, masks, prototype wafers, and expenses for development of process technologies, new packages, and software to support new products and design environments.

Foreign Currency Translation and Forward Contracts

The Company's foreign subsidiaries are considered to be extensions of the U.S. Company and any translation gains and losses related to these subsidiaries are included in other income (expense) in the consolidated statements of income.  As the U.S. dollar is utilized as the functional currency, gains and losses resulting from foreign currency transactions (transactions denominated in a currency other than the subsidiaries' functional currency) are also included in income.  For a portion of fiscal 2013, certain foreign subsidiaries acquired as part of the SMSC acquisition had the local currency as the functional currency. Once these entities were integrated into the Company's legal structure and intercompany agreements were executed, the U.S. dollar became the functional currency. Gains and losses associated with currency rate changes on forward contracts are recorded currently in income.  These gains and losses have been immaterial to the Company's financial statements.

Income Taxes

As part of the process of preparing its consolidated financial statements, the Company is required to estimate its income taxes in each of the jurisdictions in which it operates.  This process involves estimating the Company's actual current tax exposure together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes.  These differences result in deferred tax assets and liabilities, which are included within the Company's consolidated balance sheet.  The Company must then assess the likelihood that its deferred tax assets will be recovered from future taxable income and to the extent it believes that recovery is not likely, it must establish a valuation allowance.  The Company has provided valuation allowances for certain of its deferred tax assets where it is more likely than not that some portion, or all of such assets, will not be realized.  

Cash and Cash Equivalents

All highly liquid investments, including marketable securities purchased with a remaining maturity of three months or less when acquired are considered to be cash equivalents.

Investments – Available-for-Sale and Trading Securities

The Company classifies its investments in debt and marketable equity securities as available-for-sale or trading securities based upon management's intent with regard to the investments and the nature of the underlying securities. 

The Company's available-for-sale investments consist of government agency bonds, municipal bonds, auction rate securities (ARS), corporate bonds and marketable equity securities.  The Company's investments are carried at fair value with unrealized gains and losses reported in stockholders' equity unless losses are considered to be other than temporary impairments in which case the losses are recognized through the statement of income.  Premiums and discounts are amortized or accreted over the life of the related available-for-sale security.  Dividend and interest income are recognized when earned.  The cost of securities sold is calculated using the specific identification method. 

The Company includes within short-term investments its trading securities, as well as its income yielding available-for-sale securities that can be readily converted to cash and includes within long-term investments those income yielding available-for-sale securities with maturities of over one year that have unrealized losses attributable to them or those that cannot be readily liquidated.  Except as discussed in Note 5, the Company intends and has the ability to hold its long-term investments with temporary impairments until such time as these assets are no longer impaired.  Such recovery of unrealized losses is not expected to occur within the next year.

Non-Marketable Equity Investments

The Company's non-marketable equity investments are recorded using adjusted cost basis or the equity method of accounting, depending on the circumstances of each investment.  The Company's non-marketable equity investments are classified within other assets on the Company's consolidated balance sheet.  The Company's non-marketable equity investments include:

Equity Method Investments:  when the Company has the ability to exercise significant influence, but not control, over the investee, it records equity method gain or loss as "gain or loss from equity investments."  Equity method adjustments include the Company's proportionate share of the investee's income or loss.

Cost Method Investments:  when the Company does not have the ability to exercise significant influence over the investee, it records such investments at cost.

The Company reviews its investments quarterly for indicators of impairment.  The impairment review requires significant judgment and includes quantitative and qualitative analysis of identified events or circumstances that impact the fair value of the investment, such as:

• the investee's revenue and trends in earnings or losses relative to pre-defined milestones and overall business prospects;

• the technological feasibility of the investee's products and technologies;

• the general market conditions in the investee's industry or geographic area, including adverse regulatory or economic changes;

• factors related to the investee's ability to remain in business, such as the investee's liquidity, debt ratios, and the rate at which the investee is using its cash; and

• the investee's receipt of additional funding at a lower valuation.

If the fair value of an investment is below the Company's carrying value, the Company determines if the investment is other-than-temporarily impaired based on a quantitative and qualitative analysis, which includes assessing the severity and duration of the impairment and the likelihood of recovery before disposal.  If the investment is considered to be other-than-temporarily impaired, the Company writes down the investment to its fair value.  

Allowance for Doubtful Accounts

The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments, which is included in bad debt expense.  The Company determines the adequacy of this allowance by regularly reviewing the composition of its accounts receivable aging and evaluating individual customer receivables, considering such customer's financial condition, credit history and current economic conditions.

Inventories

Inventories are valued at the lower of cost or market using the first-in, first-out method.  The Company writes down its inventory for estimated obsolescence or unmarketable inventory in an amount equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions.  If actual market conditions are less favorable than those projected by the Company, additional inventory write-downs may be required.  Inventory impairment charges establish a new cost basis for inventory and charges are not subsequently reversed to income even if circumstances later suggest that increased carrying amounts are recoverable.  In estimating reserves for obsolescence, the Company primarily evaluates estimates of demand over a 12-month period and provides reserves for inventory on hand in excess of the estimated 12-month demand. Estimates for projected 12-month demand are generally based on the average shipments of the prior three-month period, which are then annualized to adjust for any potential seasonality in the Company's business. The estimated 12-month demand is compared to its most recently developed sales forecast to further reconcile the 12-month demand estimate. Management reviews and adjusts the estimates as appropriate based on specific situations. For example, demand can be adjusted up for new products for which historic sales are not representative of future demand. Alternatively, demand can be adjusted down to the extent any existing products are being replaced or discontinued.

In periods where the Company's production levels are substantially below normal operating capacity, unabsorbed overhead production costs associated with the reduced production levels of the Company's manufacturing facilities are charged directly to cost of sales.

Property, Plant and Equipment

Property, plant and equipment are stated at cost.  Major renewals and improvements are capitalized, while maintenance and repairs are expensed when incurred.  The Company's property and equipment accounting policies incorporate estimates, assumptions and judgments relative to the useful lives of its property and equipment.  Depreciation is provided for assets placed in service on a straight-line basis over the estimated useful lives of the relative assets, which range from 10 to 30 years for buildings and building improvements and 3 to 8 years for machinery and equipment.  The Company evaluates the carrying value of its property and equipment when events or changes in circumstances indicate that the carrying value of such assets may be impaired.  Asset impairment evaluations are, by nature, highly subjective.

Junior Subordinated Convertible Debentures

The Company separately accounts for the liability and equity components of its junior subordinated convertible debentures in a manner that reflects its nonconvertible debt (unsecured debt) borrowing rate when interest cost is recognized.  This results in a bifurcation of a component of the debt, classification of that component in equity and the accretion of the resulting discount on the debt to be recognized as part of interest expense in its consolidated statements of income.  Lastly, the Company includes the dilutive effect of the shares of its common stock issuable upon conversion of the outstanding junior subordinated convertible debentures in its diluted income per share calculation regardless of whether the market price trigger or other contingent conversion feature has been met.  The Company applies the treasury stock method as it has the intent and ability to settle the principal amount of the junior subordinated convertible debentures in cash.  This method results in incremental dilutive shares when the average market value of the Company's common stock for a reporting period exceeds the conversion price per share which was $25.87 at March 31, 2014 and adjusts as dividends are recorded in the future.

Litigation

The Company's estimated range of liability related to pending litigation is based on claims for which management believes a loss is probable and it can estimate the amount or range of loss.  Because of the uncertainties related to both the outcome and range of any potential losses on the pending litigation, the Company is generally unable to make a reasonable estimate of the liability that could result from an unfavorable outcome.  As additional information becomes available, the Company will assess the potential liability related to its pending litigation and revise its estimates, if necessary.

Business Combinations

All of the Company's business combinations are accounted for at fair value under the acquisition method of accounting.  Under the acquisition method of accounting, (i) acquisition-related costs, except for those costs incurred to issue debt or equity securities, will be expensed in the period incurred; (ii) non-controlling interests will be valued at fair value at the acquisition date; (iii) in-process research and development will be recorded at fair value as an intangible asset at the acquisition date and amortized once the technology reaches technological feasibility; (iv) restructuring costs associated with a business combination will be expensed subsequent to the acquisition date; and (v) changes in deferred tax asset valuation allowances and income tax uncertainties after the acquisition date will be recognized through income tax expense or directly in contributed capital.  The measurement of fair value of assets acquired and liabilities assumed requires significant judgment.  The valuation of intangible assets and acquired investments, in particular, requires that the Company use valuation techniques such as the income approach.  The income approach includes the use of a discounted cash flow model, which includes discounted cash flow scenarios and requires the following significant estimates:  revenue, expenses, capital spending and other costs, and discount rates based on the respective risks of the cash flows.  The valuation of non-marketable equity investments acquired also takes into account variables such as conditions reflected in the capital markets, recent financing activity by the investees, the investees' capital structure and the terms of the investees' issued interests.

Goodwill and Other Intangible Assets

Goodwill is recorded when the purchase price paid for an acquisition exceeds the estimated fair value of the net identified tangible and intangible assets acquired.  The Company is required to perform an annual impairment review, and more frequently under certain circumstances.  The goodwill is subjected to this test during the fourth quarter of the Company's fiscal year.  The Company engages primarily in the development, manufacture and sale of semiconductor products as well as technology licensing.  As a result, the Company concluded there are two reporting units, semiconductor products and technology licensing. Under the qualitative goodwill impairment assessment standard, management evaluates whether it is more likely than not that goodwill is impaired. If it is determined that it is more likely than not, the Company proceeds with the next step of the impairment test, which compares the fair value of the reporting unit to its carrying value.  If the Company determines through the impairment process that goodwill has been impaired, the Company will record the impairment charge in its results of operation.  Through March 31, 2014, the Company has not had impaired goodwill.  The Company's other intangible assets represent existing technologies, core and developed technology, in-process research and development, trademarks and trade names, and customer-related intangibles. Other intangible assets are amortized over their respective estimated lives, ranging from one year to ten years.  In the event that facts and circumstances indicate intangibles or other long-lived assets may be impaired, the Company evaluates the recoverability and estimated useful lives of such assets.  In-process research and development is capitalized until such time the related projects are completed or abandoned at which time the capitalized amounts will begin to be amortized or written off.

Impairment of Long-Lived Assets

The Company assesses whether indicators of impairment of long-lived assets are present.  If such indicators are present, the Company determines whether the sum of the estimated undiscounted cash flows attributable to the assets in question is less than their carrying value.  If less, the Company recognizes an impairment loss based on the excess of the carrying amount of the assets over their respective fair values.  Fair value is determined by discounted future cash flows, appraisals or other methods.  If the assets determined to be impaired are to be held and used, the Company recognizes an impairment loss through a charge to operating results to the extent the present value of anticipated net cash flows attributable to the asset are less than the asset's carrying value.  The Company would depreciate the remaining value over the remaining estimated useful life of the asset.

Share-Based Compensation

The Company has equity incentive plans under which non-qualified stock options and restricted stock units (RSUs) have been granted to employees and non-employee members of the Board of Directors.  In the second half of fiscal 2006, the Company adopted RSUs as its primary equity incentive compensation instrument for employees.  The Company also has an employee stock purchase plan for all eligible employees.

The Company estimates the fair value of share-based payment awards on the date of grant using an option pricing model.  The value of the portion of the award that is ultimately expected to vest is recognized as expense ratably over the requisite service periods.  The Company has estimated the fair value of each award as of the date of grant using the Black-Scholes option pricing model, which was developed for use in estimating the value of traded options that have no vesting restrictions and that are freely transferable.  

Determining the appropriate fair-value model and calculating the fair value of share-based awards at the date of grant requires judgment.  The fair value of RSUs is based on the fair market value of the Company's common stock on the date of grant discounted for expected future dividends.  The Company uses the Black-Scholes option pricing model to estimate the fair value of employee stock options and rights to purchase shares under stock participation plans.  Option pricing models, including the Black-Scholes model, also require the use of input assumptions, including expected volatility, expected life, expected dividend rate, and expected risk-free rate of return.  The Company uses a blend of historical and implied volatility based on options freely traded in the open market as it believes this is more reflective of market conditions and a better indicator of expected volatility than using purely historical volatility.  The expected life of the awards is based on historical and other economic data trended into the future.  The risk-free interest rate assumption is based on observed interest rates appropriate for the expected terms of the Company's awards.  The dividend yield assumption is based on the Company's history and expectation of future dividend payouts.  The Company estimates the number of share-based awards which will be forfeited due to employee turnover.  Quarterly changes in the estimated forfeiture rate would affect share-based compensation, as the impact on prior period amortization for all unvested awards is recognized in the period the forfeiture estimate is changed.  If the actual forfeiture rate is higher than the estimated forfeiture rate, then an adjustment is made to increase the estimated forfeiture rate, which will result in a decrease to the expense recognized in the financial statements.  If the actual forfeiture rate is lower than the estimated forfeiture rate, then an adjustment is made to decrease the estimated forfeiture rate, which will result in an increase to the expense recognized in the financial statements.  If forfeiture adjustments are made, they would affect the Company's results of operations.  The effect of forfeiture adjustments in the years ended March 31, 2014, 2013 and 2012 was immaterial.

The Company evaluates the assumptions used to value its awards on a quarterly basis.  If factors change and the Company employs different assumptions, share-based compensation expense may differ significantly from what was recorded in the past.  If there are any modifications or cancellations of the underlying unvested securities, the Company may be required to accelerate or increase any remaining unearned share-based compensation expense.  Future share-based compensation expense and unearned share-based compensation will increase to the extent that the Company grants additional equity awards to employees or it assumes unvested equity awards in connection with acquisitions.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of investments in debt securities and trade receivables.  Investments in debt securities with original maturities of greater than six months consist primarily of AAA and AA rated financial instruments and counterparties.  The Company's investments are primarily in direct obligations of the U.S. government or its agencies, corporate bonds, and municipal bonds.

Concentrations of credit risk with respect to accounts receivable are generally not significant due to the diversity of the Company's customers and geographic sales areas.  The Company sells its products primarily to OEMs and distributors in the Americas, Europe and Asia.  The Company performs ongoing credit evaluations of its customers' financial condition and, as deemed necessary, may require collateral, primarily letters of credit.

Distributor advances, included in deferred income on shipments to distributors in the consolidated balance sheets, totaled $92.8 million at March 31, 2014 and $70.1 million at March 31, 2013.  On sales to distributors, the Company's payment terms generally require the distributor to settle amounts owed to the Company for an amount in excess of their ultimate cost.  The Company's sales price to its distributors may be higher than the amount that the distributors will ultimately owe the Company because distributors often negotiate price reductions after purchasing the product from the Company and such reductions are often significant.  It is the Company's practice to apply these negotiated price discounts to future purchases, requiring the distributor to settle receivable balances, on a current basis, generally within 30 days, for amounts originally invoiced.  This practice has an adverse impact on the working capital of the Company's distributors.  As such, the Company has entered into agreements with certain distributors whereby it advances cash to the distributors to reduce the distributor's working capital requirements.  These advances are reconciled at least on a quarterly basis and are estimated based on the amount of ending inventory as reported by the distributor multiplied by a negotiated percentage.  Such advances have no impact on revenue recognition or the Company's consolidated statements of income.  The Company processes discounts taken by distributors against its deferred income on shipments to distributors' balance and trues-up the advanced amounts generally after the end of each completed fiscal quarter.  The terms of these advances are set forth in binding legal agreements and are unsecured, bear no interest on unsettled balances and are due upon demand.  The agreements governing these advances can be canceled by the Company at any time.

Use of Estimates

The Company has made a number of estimates and assumptions relating to the reporting of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities to prepare its consolidated financial statements in conformity with U.S. Generally Accepted Accounting Principles.  Actual results could differ from those estimates.

Recently Issued Accounting Pronouncements

In May of 2014 the FASB issued Accounting Standard Update 2014-09-Revenue from Contracts with Customers, which will supersede nearly all existing revenue recognition guidance under US GAAP.  The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The Company is carefully evaluating its existing revenue recognition policies to determine whether any contracts in the scope of the guidance will be affected by the new requirements.  The effects may include identifying performance obligations in existing arrangements, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation.  The new standard is effective beginning the first quarter of the Company’s 2018 fiscal year.  Early adoption is not permitted.  The standard allows for either “full retrospective” adoption, meaning the standard is applied to all of the periods presented, or “modified retrospective” adoption, meaning the standard is applied only to the most current period presented in the financial statements.  The Company is currently evaluating the transition method that will be elected.

In the first quarter of fiscal 2014, the Company adopted the provisions of Accounting Standard Update 2013-02 Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which required the disclosure of amounts reclassified out of accumulated other comprehensive income (AOCI) to net income. The adoption of this provision did not have a material impact on the Company's consolidated financial statements and related disclosures.

Employee Benefit Plans [Text Block]

EMPLOYEE BENEFIT PLANS

The Company maintains a contributory profit-sharing plan for its domestic employees meeting certain eligibility and service requirements.  The plan qualifies under Section 401(k) of the Internal Revenue Code of 1986, as amended, and allows employees to contribute up to 60% of their base salary, subject to maximum annual limitations prescribed by the IRS.  The Company has a discretionary matching contribution program. All matches are provided on a quarterly basis and require the participant to be an active employee at the end of each quarter.  For fiscal 2014, the Company contributions to the plan totaled $3.6 million.  For fiscal 2013, the Company contributions to the plan totaled $0.8 million. For fiscal 2012, the Company contributions to the plan totaled $1.6 million.

The Company's 2001 Employee Stock Purchase Plan (the 2001 Purchase Plan) became effective on March 1, 2002.  The Board of Directors approved the 2001 Purchase Plan in May 2001 and the stockholders approved it in August 2001.  Under the 2001 Purchase Plan, eligible employees of the Company may purchase shares of common stock at semi-annual intervals through periodic payroll deductions.  The purchase price in general will be 85% of the lower of the fair market value of the common stock on the first day of the participant's entry date into the offering period or of the fair market value on the semi-annual purchase date.  Depending upon a participant's entry date into the 2001 Purchase Plan, purchase periods under the 2001 Purchase Plan consist of overlapping periods of either 24, 18, 12 or 6 months in duration.  In May 2003 and August 2003, the Company's Board and stockholders, respectively, each approved an annual automatic increase in the number of shares reserved under the 2001 Purchase Plan.  The automatic increase took effect on January 1, 2005, and on each January 1 thereafter during the term of the plan, and is equal to the lesser of (i) 1,500,000, (ii) one half of one percent (0.5%) of the then outstanding shares of the Company's common stock, or (iii) such lesser amount as is approved by Board of Directors.  Upon the approval of the Board of Directors, there were no shares added under the 2001 Purchase Plan on January 1, 2014 or January 1, 2013 based on the automatic increase provision. On January 1, 2012, an additional 960,269 shares were reserved under the 2001 Purchase Plan based on the automatic increase.  Since the inception of the 2001 Purchase Plan, 11,277,862 shares of common stock have been reserved for issuance and 5,641,704 shares have been issued under this purchase plan.

During fiscal 1995, a purchase plan was adopted for employees in non-U.S. locations.  Such plan provided for the purchase price per share to be 100% of the lower of the fair market value of the common stock at the beginning or end of the semi-annual purchase plan period.  Effective May 1, 2006, the Company's Board approved a purchase price per share equal to 85% of the lower of the fair market value of the common stock at the beginning or end of the semi-annual purchase plan period.  Since the inception of this purchase plan, 1,500,285 shares of common stock have been reserved for issuance and 830,277 shares have been issued under this purchase plan.

Effective January 1, 1997, the Company adopted a non-qualified deferred compensation arrangement.  This plan is unfunded and is maintained primarily for the purpose of providing deferred compensation for a select group of highly compensated employees as defined in ERISA Sections 201, 301 and 401.  There are no Company matching contributions made under this plan.

In connection with the acquisition of SMSC, the Company assumed an unfunded Supplemental Executive Retirement Plan ("SERP"), which provides former SMSC senior management with retirement, disability and death benefits. An amendment to the SERP was executed on November 3, 2009, freezing the benefit level for existing participants as of February 28, 2010 and closing the SERP to new participants. As of March 31, 2014, the projected benefit obligation is $6.3 million. Annual benefit payments and contributions under this plan are expected to be approximately $0.8 million in fiscal 2015 and approximately $4.5 million cumulatively in fiscal 2016 through fiscal 2024.

The Company has management incentive compensation plans which provide for bonus payments, based on a percentage of base salary, from an incentive pool created from operating profits of the Company, at the discretion of the Board of Directors.  During fiscal 2014, 2013 and 2012, $24.4 million, $12.0 million and $7.8 million were charged against operations for these plans, respectively.

The Company also has a plan that, at the discretion of the Board of Directors, provides a cash bonus to all employees of the Company based on the operating profits of the Company.  During fiscal 2014, 2013 and 2012, $15.2 million, $4.3 million and $3.2 million, respectively, were charged against operations for this plan.

The Company amortizes intangible assets over their expected useful lives, which range between 1 and 15 years.  In fiscal 2014, the Company acquired $12.7 million of developed technology which has a weighted average amortization period of 11 years, $1.3 million of customer-related intangible assets which has a weighted average amortization period of 5 years, $0.3 million of distribution rights which has a weighted average amortization period of 10 years and $0.8 million of in-process technology which will begin amortization once the technology reaches technological feasibility. The following is an expected amortization schedule for the intangible assets for fiscal 2015 through fiscal 2019, absent any future acquisitions or impairment charges (amounts in thousands):

Year ending March 31,	Projected Amortization Expense
2015	$132,951
2016	91,711
2017	61,997
2018	46,724
2019	38,730

Amortization expense attributed to intangible assets was $99.4 million, $115.8 million and $13.0 million for fiscal years 2014, 2013 and 2012, respectively.  In fiscal 2014, approximately $4.7 million was charged to cost of sales and approximately $94.7 million was charged to operating expenses.  In fiscal 2013, approximately $3.9 million was charged to cost of sales and approximately $111.9 million was charged to operating expenses.  In fiscal 2012, $1.4 million was charged to cost of sales and $11.6 million was charged to operating expenses.  The Company recognized impairment charges of $0.4 million in fiscal 2014. The Company found no indication of impairment of its intangible assets in fiscal 2013 or 2012.

Goodwill activity for fiscal years 2014 and 2013 was as follows (amounts in thousands):

	Semiconductor Products Reporting Unit			Technology Licensing Reporting Unit
Balance at March 31, 2012	$	74,313		$	19,200
Additions due to the acquisition of SMSC	169,065			—
Additions due to the acquisition of Roving Networks	8,652			—
Additions due to contingent consideration payments	118			—
Balance at March 31, 2013	252,148			19,200
Adjustments due to the acquisition of SMSC	(3,473		)	—
Additions due to other acquisitions	8,111			—
Additions due to contingent consideration payments	111			—
Balance at March 31, 2014	$	256,897		$	19,200

In fiscal 2014, the Company completed several acquisitions which resulted in goodwill of approximately $8.1 million which was allocated to the semiconductor products reporting unit. Also, during fiscal 2014, the Company made adjustments to the purchase price allocation of its SMSC acquisition of approximately $3.5 million.

In fiscal 2013, the Company acquired SMSC and Roving Networks. The SMSC acquisition resulted in approximately $169.1 million of goodwill which was allocated to the semiconductor products reporting unit. The Roving Networks acquisition resulted in approximately $8.7 million of goodwill which was allocated to the semiconductor products reporting unit.

At March 31, 2014, $256.9 million of goodwill was recorded in the Company's semiconductor products reporting unit and $19.2 million was recorded in the Company's technology licensing reporting unit. At March 31, 2014, the Company applied a qualitative goodwill impairment screen to its two reporting units, concluding it was not more likely than not that goodwill was impaired. Through March 31, 2014, the Company has never recorded an impairment charge against its goodwill balance.
