Business and Macroeconomic Environment

The COVID-19 pandemic initially resulted in sharesa global disruption in economic activity by adversely affecting production, creating supply chain and market disruption, and adversely impacting businesses and individuals. However, in the second half of Microchip common stock.fiscal 2021, business conditions were unexpectedly strong as businesses and individuals adapted to the effects of the pandemic. In response to global supply constraints, we worked to mitigate the impact of the pandemic on our business by qualifying alternative suppliers, increasing our inventory of raw materials, ramping our internal factories and adding assembly and test capacity to increase our manufacturing capability while securing additional capacity with our subcontractors wherever possible. However, strong customer demand outpaced capacity improvements in fiscal 2022 as we continued to experience constraints in our internal and external factories and their related manufacturing supply chains. We financedexpect that certain supply chain constraints will persist through calendar 2022 and into calendar 2023. In order to provide prioritized capacity to our customers, we launched our Preferred Supply Program in February 2021, which provides our customers with prioritized capacity beginning six months after the purchase pricecustomer places an order for 12 months of continuous, non-cancellable and non-reschedulable backlog.

In response to the pandemic, we have taken proactive preventative measures to enable a safe environment for our employees and operation of our Atmel acquisition using approximately $2.04 billionmanufacturing sites. While our global manufacturing sites are fully operational, we strategically implemented plans intended to provide more assurance of cash, cash equivalents, short-term investments and long-term investments held by certain of our foreign subsidiaries, approximately $0.94 billion from additional borrowings under our existing line of credit agreement and approximately $489 million by issuing an aggregate of 10.1 million shares of our common stock. The acquisition price represents a total equity value of approximately $3.47 billion, and a total enterprise value of approximately $3.43 billion, after excluding Atmel's cash and investments net of debt of approximately $39.3 million. Atmel is a worldwide leaderbusiness continuity in the design and manufacture of microcontrollers, capacitive touch solutions, advanced logic, mixed-signal, nonvolatile memory and RF components.

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 a portion of the wafer manufacturing and 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 in recent years due to our acquisitions of Microsemi and other companies that outsourceoutsourced all or substantial portions of their manufacturing. We comply with several quality systems, including: ISO9001 (2015 version), IATF16949 (2016 version), AS9100 (2016 version), and TL9000.


OurRefer to "Item 2. Properties" for further information regarding the location and principal operations of our manufacturing facilities are located in:facilities.

Wafer Fabrication
 
Fab 2 currently produces 8-inch wafers and supports various manufacturing processes from 0.35process technologies, but predominantly utilizes our 0.25 microns to 5.0 microns.1.0 microns processes.  During fiscal 2016,2022, we increased Fab 2's capacity to support more advanced technologies by making process improvements, upgrading existing equipment, and adding equipment.
 
Fab 4 currently produces 8-inch wafers using predominantly 0.220.13 microns to 0.5 microns manufacturing processes and is capable of supporting technologies below 0.18 microns.processes.  During fiscal 2016,2022, we increased Fab 4's capacity to support more advanced technologies by making process improvements, upgrading existing equipment, and adding equipment. A significant amount of additional clean room capacity in Fab 4 can beis being brought on line in the future to support incremental wafer fabrication capacity needs. 

Fab 5 currently manufactures discrete and specialty products in addition to a lower volume of a diversified set of standard products.

We believe the combined capacity of Fab 2, Fab 4, and Fab 45 will provide sufficient capacity to allow us to respond to increases in future demand over the next several yearsof internally fabricated products with modest incremental capital expenditures.


As a result of our acquisition of Micrel, Incorporated (Micrel) in August 2015,Microsemi, we acquired a 6-inch fabseveral smaller wafer fabrication facilities, which utilize older technologies that are appropriate for the discrete products they manufacture. We currently plan to continue to operate these fabrication facilities with modest investment to keep them operational with the exception of the facility in San Jose,Santa Clara, California, and arewhich we closed in the process of providing last time inventory for our customers as we transition those products into our Fab 2 and Fab 4 facilities. We intend to start decommissioning the San Jose Fab in late fiscal 2017.2022.

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, outsourcedaugment our internal manufacturing capabilities by outsourcing a largersignificant portion of our wafer production requirements to third-party wafer foundries to augment our internal manufacturing capabilities.foundries.  As a result of our acquisitions, in recent years, we have become more reliant on outside wafer foundries for our wafer fabrication requirements.  In fiscal 2016,2022, approximately 39%60% 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 testingtest at various facilities located around the world. During fiscal 2022, we increased capacity at our facilities located near Bangkok, Thailand.  We also perform a limited amount of wafer probeThailand and test at our Chandler, Arizona and San Jose, California facilities. During fiscal 2016, we increased our Thailand facilities' capacityPhilippines facilities to support more technologies by making process improvements, upgrading existing equipment, and adding equipment. During fiscal 2016,2022, approximately 53%59% of our assembly requirements were being performed in our Thailandinternal facilities and approximately 81%64% of our test requirements were performed in our Thailandinternal facilities.  We

use third-party assembly and test contractors in several Asian countries for the balance of our assembly and test requirements. Over time, we intend to continue to migrate a portion of the outsourced assembly and test activities to our internal facilities.

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 complementary metal-oxide semiconductor (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 or above 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 Refer to Note 3 for a summary of fiscal 2016, we owned identifiableour long-lived assets, (consistingconsisting of property, plant and equipment) in the U.S. with a carrying value, net of accumulated depreciation, of $373.9 millionequipment and $235.5 million in other countries, including $182.8 million in Thailand. At the end of fiscal 2015, we owned identifiable long-livedright-of-use assets, (consisting of property, plant and equipment) in the U.S. with a carrying value, net of accumulated depreciation, of $331.4 million and $250.2 million in other countries, including $198.0 million in Thailand.  At the end of fiscal 2014, we owned identifiable long-lived assets 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.by geography.

We have many suppliers of raw materials and subcontractors whichthat 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, wired and wireless connectivity products, analog, interface, mixed signal and timing products, Serial EEPROM memory, NOR FLASH memory, Embedded FLASH technologies, development systems, human 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 2016, our R&D expenses were $372.6 million, compared to $349.5 million in fiscal 2015 and $305.0 million in fiscal 2014.  R&D expenses included share-based compensation expense of $32.0 million in fiscal 2016, $28.2 million in fiscal 2015 and $24.6 million in fiscal 2014.

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 client engagement managers (CEMs), embedded system engineers (ESEs),CEMs, ESEs, and sales management have technical degrees or backgrounds and have been previously employed in high technology environments.  We believe that the technical and business knowledge of our sales force is a key competitive advantage in the sale of our products.  The primary mission of our ESE team is to provide technical assistance to customers and to conduct periodic training sessions for the balance of our sales team.  ESEs also frequently conduct technical seminars and workshops in major cities around the world.world or through online webcasts.
 
Our licensing division has dedicated sales, technology, design, product, test and reliability personnel that support the requirements of our licensees.
 
For information regarding our revenue, results of operations, and total assets for each of our last three fiscal years, refer to our financial statements included in this Form 10-K.


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 fiscal 2016,2022 and fiscal 2021, we derived 53%48% and 50%, respectively, of our net sales through distributors compared to 52% and 47%50%, respectively, of our net sales from customers serviced directly by us. In fiscal 2015, we derived 51%The decrease in the distribution percentage of our total net sales throughwas primarily due to lower Preferred Supply Program participation among our distributors and 49%as priority of our net sales from customers serviced directly by us. In fiscal 2014, we derived 53% of our net sales through distributors and 47% of our net sales from customers serviced directly by us.supply under the Preferred Supply Program is more prevalent with direct customers. No distributor or end customer accounted for more than 10% of our net sales in fiscal 2016, fiscal 20152022 or fiscal 2014.2021.

With the exception of orders placed under our Preferred Supply Program, we do not have long-term agreements withpurchase commitments from 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 2016, fiscal 2015 and fiscal 2014 were as follows (dollars in thousands):

Sales to foreign customers accounted for approximately 84% of our net sales in each of fiscal 2016, 2015 and 2014.  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 30%, 28% and 29% of our net sales in fiscal 2016, 2015 and 2014, respectively.  Sales to customers in Taiwan accounted for approximately 12%, 14% and 13% of our net sales in fiscal 2016, 2015 and 2014, respectively. We did not have sales into any other foreign countries that exceeded 10% of our net sales during fiscal 2016, fiscal 2015 or fiscal 2014.

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, the impact of our acquisitions, 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, 2016, our backlog was approximately $1,212.3 million, including approximately $360.0 million related to Atmel, compared to $765.0 million as of April 30, 2015, which excludes Atmel.  Our backlog includes all purchase orders scheduled for delivery within the subsequent 12 months.

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 historically been characterized by price erosion and rapid technological change.  We compete with major domestic and international semiconductor companies, manysome 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 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
performance
analog, digital and mixed signal functionality and level of functional integration
field programmability
memory density
low power consumption
extended voltage ranges
reliability
security and functional safety
packaging alternatives
completecomprehensive suite of development tool linetools


We believe that other important competitive factors in the embedded control market include:
ease of use
functionality of application development systems
hardware, software and tool compatibility within product families to increase migration flexibility
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 2016 and 2035.from 2022 through 2041.  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 our intention is to continue to patent 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.  As with any operating company, the scope and strength of our intellectual property assets, including our pending and existing patents, trademarks, copyrights, and other intellectual property rights may be insufficient to provide meaningful protection or commercial advantage.  Moreover, pursuing violations of intellectual property rights on a worldwide basis is a complex challenge involving multinational patent, trademark, copyright and trade secret laws. Further, the laws of particular foreign countries often fail to protect our intellectual property rights to the same extent as the laws of the U.S.
 
We have also entered into certain in-bound and outbound intellectual property licenses and cross-licenses with other companies and those licenses relate to semiconductor products and manufacturing processes.  As is typical in the semiconductor industry, we and our customers from time to time receive, and may continue to receive, demand letters from third parties asserting infringement of patent and other intellectual property rights.  We diligently investigate all such notices and respond as we believe appropriate.  In most cases we believe that we can obtain necessary licenses on commercially reasonable terms, however, we cannot be certain that this would be the case, or that litigation or damages for any past
9

Table of Contents
infringement could be avoided. Licensees of our technology may become unable to pay, and have in the past and are currently disputing their obligations to pay us royalties or fees. Litigation, arbitration or other proceedings, which could result in substantial costs and require significant attention from management, mayhas been and is expected to be necessary to enforce our intellectual property rights, or to defend against claimed infringement of the rights of others.  The failure to obtain necessary licenses, or the necessity of engaging in defensive litigation,legal proceedings, or any negative results of these proceedings 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 acquireresult in an increase in capital expenditures such as acquiring 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, technological changes, or weather, 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.

Risks Related to Our Business, Operations, and Industry

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, public health or political conditions in the U.S. or internationally;internationally, including uncertain economic conditions in China or the ongoing uncertainty surrounding the COVID-19 pandemic and its implications;
disruptions in our business, our supply chain or our customers' businesses due to public health concerns (including viral outbreaks such as COVID-19), cybersecurity incidents, terrorist activity, armed conflict, war (including Russia's invasion of the Ukraine), worldwide oil prices and supply, fires, natural disasters or disruptions in the transportation system;

rising interest rates or inflation; and
property damage or other losses, whether or not covered by insurance.


We believe that period-to-periodPeriod-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. AdverseUncertain global economic and public health conditions, such as the subsequent economic recovery and uncertainty surrounding the strength and duration of such recoveryCOVID-19 pandemic, have caused and may in the future cause our operating results to fluctuate significantly and make comparabilitycomparisons between periods less meaningful.

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. Any downturn in global or regional economic conditions, as a result of the COVID-19 pandemic, the enactment of broad sanctions by the U.S. or other countries against Russia, or risks of rising interest rates or inflation, may adversely impact their financial viability. 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 inability to collect our accounts receivable balances, higher allowances for credit losses, and higher operating costs as a percentage of net sales.

We may lose sales if suppliers of raw materials, components or equipment fail to meet our or our customers' needs, increase prices or are impacted by increases in tariffs.

Our manufacturing operations require raw and processed materials and equipment that must meet exacting standards.  We generally have multiple sources for these supplies, but there may be a limited number of suppliers capable of meeting our standards.  We have experienced supply shortages from time to time in the past, and on occasion our suppliers have told us they need more time to fill our orders, that they cannot fill certain orders, that they will no longer support certain equipment with updates or parts, or that they are increasing prices. In particular, in fiscal 2022, we experienced increased prices at certain suppliers, and longer lead times for some assembly raw materials required for production purposes. Such conditions are expected to continue. An interruption of any materials or equipment sources, or the lack of supplier support for a particular piece of equipment, could harm our business. The supplies necessary for our business could become more difficult to obtain as worldwide use of semiconductors increases, or due to supply chain disruptions or political instability. Additionally, consolidation in our supply chain due to mergers and acquisitions may reduce the number of suppliers or change our relationships with them. Also, the reduced availability of necessary labor, the impact of the COVID-19 pandemic, or the application of sanctions, trade restrictions or tariffs by the U.S. or other countries may adversely impact the industry supply chain. For example, in 2019, the U.S. government increased tariffs on U.S. imports with China as their country of origin. Likewise, the China government increased tariffs on China imports with U.S. as their country of origin. We have taken steps to attempt to mitigate the costs of these tariffs on our business. Although these increases in tariffs did not significantly increase the operating costs of our business, they did, however, adversely impact demand for our products during fiscal 2020 and fiscal 2019. The additional tariffs imposed on components or equipment that we or our suppliers source from China will increase our costs and could have an adverse impact on our operating results in future periods. We may also incur increases in manufacturing costs in mitigating the impact of tariffs on our operations. This could also impair sourcing flexibility.

Our customers may also be adversely affected by these same issues. The labor, supplies and equipment necessary for their businesses could become more difficult to obtain for various reasons not limited to business interruptions of suppliers, reduced availability of labor, consolidation in their supply chain, the impact of the COVID-19 pandemic, or sanctions, trade restrictions or tariffs that impair sourcing flexibility or increase costs. If our customers are not able to produce their products, then their need for our products will decrease. Such interruptions of our customers’ businesses could harm our business.

We do not purchase significant amounts of equipment from Russia, Belarus, or the Ukraine. However, the semiconductor industry, and purchasers of semiconductors, use raw materials that are sourced from these regions, such as neon, palladium and nickel. If we, or our direct or indirect customers, are unable to obtain the requisite raw materials or components needed to manufacture products, our ability to manufacture products, or demand for our products, may be adversely impacted. This could have a material adverse effect on our business, results of operations or financial condition. While there has been an adverse impact on the world’s palladium and neon supply chains, at this time, our palladium and neon supply chains have been able to meet our needs. While sales of our products into the regions, and to customers that sell into these regions, have been negatively impacted by the Russian invasion of the Ukraine, at this time, we have not experienced a material impact on our business, results of operations or financial conditions.

We are dependent on wafer foundries and other contractors, as are our SuperFlash and other licensees.

We rely on outside wafer foundries for a significant portion of our wafer fabrication needs. Specifically, during fiscal 2022 and fiscal 2021, approximately 60% and 61%, respectively, of our net sales came from products that were produced at outside wafer foundries. We also use several contractors located primarily in Asia for a portion of the assembly and testing of our products. Specifically, during fiscal 2022, approximately 41% of our assembly requirements and 36% of our test requirements were performed by third-party contractors compared to approximately 47% of our assembly requirements and 43% of our test requirements during fiscal 2021. Due to increased demand for our products, we have taken actions in recent quarters to increase our capacity allocation from our wafer fabrication, assembly and test subcontractors. However, we expect foundry capacity to continue to be limited due to strong demand for wafers across the industry and there can be no assurance that we will be able to secure the necessary allocation of capacity from our wafer foundries and other contractors, further additional capacity with the ability to manufacture the process technologies that we need, or that such capacity will be available on acceptable terms. As our manufacturing subcontractors move to more advanced process technologies over time, we may find that they do not invest in some of the trailing edge process technologies on which a large portion of our products are manufactured. If this occurs, it may limit the amounts of net sales that we can achieve or require us to make significant investments to be able to manufacture these products in our own facilities or at other foundries and assembly and testing contractors. We expect that our reliance on third-party contractors may increase over time as our business grows, and any inability to secure necessary external capacity could adversely affect our operating results.

Our use of third parties reduces our control over the subcontracted portions of our business. Our future operating results could suffer if a significant contractor were to experience production difficulties, insufficient capacity, decreased manufacturing, reduced availability of labor, assembly and test yields, or increased costs due to disruptions from the COVID-19 pandemic, political upheaval or infrastructure disruption. Additionally, our future operating results could suffer if our wafer foundries and other contractors increase the prices of the products and services that they provide to us. Some of our subcontractors in China experienced production difficulties due to COVID-19 related disruptions in March 2022, but this did not have a significant impact on our operating results. If third parties do not timely deliver products or services in accordance with our quality standards, we may be unable to qualify alternate manufacturing sources in a timely manner or on favorable terms, or at all. Additionally, these subcontractors could abandon processes that we need, or fail to adopt technologies that we desire to control costs. In such event, we could experience an interruption in production, an increase in manufacturing costs or a decline in product reliability, and our business and operating results could be adversely affected. Further, use of subcontractors increases the risks of misappropriation of our intellectual property.

Certain of our SuperFlash and other technology licensees rely on wafer foundries. If our licensees experienced disruption in supply at such foundries, this would reduce the revenue from our technology licensing business and would harm our operating results.

We are highly dependent on foreign sales, suppliers, 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 2022, approximately 78% of our net sales were made to foreign customers, including 22% in China and 15% in Taiwan. During fiscal 2021, approximately 77% of our net sales were made to foreign customers, including 22% in China and 16% in Taiwan.

A strong position in the Chinese market is a key component of our global growth strategy. Although our sales in the Chinese market have been strong in recent quarters, competition in China is intense, and China's economic growth has been projected to slow in calendar 2022. In the past, economic weakness in the Chinese market adversely impacted our sales volumes in China. As discussed above, the trade relationship between the U.S. and China remains challenging, economic conditions in China remain uncertain, and we are unable to predict whether such uncertainty will continue or worsen in future periods. Additionally, the impact of COVID-19 related lockdowns in the first quarter of calendar 2022 has adversely impacted Chinese customers and the supply chain. Weakening of foreign markets could result in lower demand for our products, which could have a material adverse effect on our business, results of operations or financial conditions.

We purchase a substantial portion of our raw materials and equipment from foreign suppliers. In addition, we own product assembly and testing facilities, and finished goods warehouses near Bangkok, Thailand, which has experienced periods of political instability and severe flooding in the past. There can be no assurance that any future flooding or political instability in Thailand would not have a material adverse impact on our operations. We have a test facility in Calamba, Philippines. We use foundries and other foreign contractors for a significant portion of our assembly and testing and wafer fabrication requirements.

We do not have significant sales or operations in Russia, Belarus, or the Ukraine, and we do not purchase significant amounts of equipment from these regions. However, the semiconductor industry, and purchasers of semiconductors, use raw materials that are sourced from these regions, such as neon, palladium and nickel. If we, or our direct or indirect customers, are unable to obtain the requisite raw materials or components needed to manufacture products, our ability to manufacture products, or demand for our products, may be adversely impacted. This could have a material adverse effect on our business, results of operations or financial condition. While there has been an adverse impact on the world’s palladium and neon supply chains due to the Russia Ukraine conflict, at this time, our palladium and neon supply chains have been able to meet our needs. While sales of our products into the regions impacted by the Russia Ukraine conflict, and to customers that sell into these regions, have been negatively impacted by the Russian invasion of the Ukraine, at this time, we have not experienced a material impact on our business, results of operations or financial condition.

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 due to the COVID-19 pandemic or other factors;
trade restrictions and changes in tariffs;
supply chain disruptions or delays;
potentially adverse tax consequences;
economic uncertainty in the worldwide markets served by us;
import and export license requirements and restrictions;
changes in laws related to taxes, environmental, health and safety, technical standards and consumer protection;
currency fluctuations and foreign exchange regulations;
difficulties in staffing and managing international operations;
employment regulations;
disruptions due to cybersecurity incidents;
disruptions in international transport or delivery;
public health conditions (including viral outbreaks such as COVID-19); and
difficulties in collecting receivables and longer payment cycles.

If any of these risks occur or are worse than we anticipate, our sales could decrease and our operating results could suffer, we could face an increase in the cost of components, production delays, business interruptions, delays in obtaining export licenses, tariffs and other restrictions, longer payment cycles, increased taxes, restrictions on the repatriation of funds and the burdens of complying with a variety of foreign laws, any of which could ultimately have a material adverse effect on our business. Further changes in trade policy, tariffs, additional taxes, or restrictions on supplies, equipment, and raw materials including rare earth minerals, may limit our ability to produce products, increase our selling and/or manufacturing costs, decrease margins, reduce the competitiveness of our products, or inhibit our ability to sell products or purchase necessary equipment and supplies, which could have a material adverse effect on our business, results of operations, or financial conditions.

We depend on orders that are received and shipped in the same quarter and have limited visibility to product shipments other than orders placed under our Preferred Supply Program.

Our net sales in any given quarter depend upon a combination of shipments from backlog, and orders that are both received and shipped in the same quarter, which we call 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, our ability to respond quickly to customer orders has been 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 visibility on future shipments. Turns orders correlate to overall semiconductor industry conditions and product lead times. Although our backlog has been very strong in recent periods due to favorable industry conditions and the impact of our Preferred Supply Program, turns orders remain important to our ability to meet our business objectives. Because turns orders can be difficult to predict, especially in times of economic volatility where customers may change order levels within the quarter, varying levels of turns orders make it more difficult to forecast net sales. The level of turns orders may also decrease in periods where customers are holding excess inventory of our products. Our customers may have increased their order levels in previous periods to help ensure they have sufficient inventory of our products to meet their needs, or they may have been unable to sell their products at their forecasted levels. 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 or effectively manage our production based on changes in order forecasts, our revenue and operating results will likely suffer.

In February 2021, we announced our Preferred Supply Program which offers our customers the ability to receive prioritized capacity. To participate in the program, customers have to place 12 months of orders, which cannot be cancelled or rescheduled except in the event of price increases. The capacity priority began for shipments in July 2021. The program is not a guarantee of supply; however, it will provide the highest priority for those orders which are under this program, and the capacity priority will be on a first-come, first-served basis until the available capacity is booked. A significant portion of our capacity is booked under this new program. We believe this program will enable us to be in a stronger position to make capacity and raw material commitments to our suppliers, buy capital equipment with confidence, hire employees and ramp up manufacturing and manufacture products more efficiently. Since this is a new program, there can be no assurance that the program will be successful or that it will benefit our business. In the event that customers under this program attempt to cancel or reschedule orders, we may have to take legal or other action to enforce the terms of the program, and any such actions could result in damage to our customer relationships or cause us to incur significant costs. Additionally, as orders under this program cannot be cancelled or returned except in the event of price increases, this may result in customers holding excess inventory of our products and thus decrease their need to place new orders in later periods.

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

The semiconductor industry is intensely competitive and faces 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. The semiconductor industry has experienced significant consolidation in recent years which has resulted in several of our competitors becoming much larger in terms of revenue, product offerings and scale. 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, including, but not limited to:
the relative impact of the COVID-19 pandemic on us relative to our competitors;
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;
our ability to obtain adequate foundry and assembly and test capacity and supplies at acceptable prices;
our ability to ramp production and increase capacity, at our wafer fabrication and assembly and test facilities;
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 applications and the success of such applications;
the rate at which the markets that we serve redesign and change their own products;
product introductions by our competitors;
the number, nature and success of our competitors in a given market;
our ability to protect our products and processes by effective utilization of intellectual property rights;
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 a product.  The average selling prices of our microcontroller, FPGA products, and proprietary products in our analog product line have remained relatively constant over time, while average selling prices of our memory and non-proprietary products in our analog product line have declined over time. The overall average selling price of our products is affected by these trends; however, variations in our product and geographic mix of sales can cause wider fluctuations in our overall average selling price in any given period.

We have experienced, and may experience in the future, modest pricing declines in certain of our more mature proprietary product lines, primarily due to competitive conditions. At this time, we are not experiencing these types of pricing declines due to favorable industry conditions and demand. In the past, we have moderated average selling price declines in many of our proprietary product lines by introducing new products with more features and higher prices. However, we may not be able to do so in the future. We have experienced in the past, and may experience in the future, competitive pricing pressures in our memory and non-proprietary products in our analog product line. At this time, we are not experiencing these types of pricing declines due to favorable industry conditions and demand. In fiscal 2022, we experienced cost increases which we were able to pass on to our customers. However, in the future, we may be unable to maintain average selling prices due to increased pricing pressure, which could adversely impact our operating results.

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


The manufacture and assembly of integratedIntegrated circuits particularly non-volatile, erasable CMOS memory and logic devices such as those that we produce,manufacturing processes are complex processes. These processes areand sensitive to a wide variety ofmany factors, including the level of contaminants in the
17

Table of Contents
manufacturing environment impurities in theor 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 or above approximately the current levels. This could include delays in the recognition of revenue, loss of revenue, or future orders, and customer-imposed penalties for our failure to meet contractual shipment deadlines. Our

operating results are also adversely affected when we operate below normal capacity. In fiscal 2022, we operated at lessabove normal capacity levels and we expect this to continue if the current supply constraints relative to demand continue. In fiscal 2021, we operated at below normal capacity levels resulting in unabsorbed capacity charges of $29.6 million.

Our operating results are impacted by seasonality and wide fluctuations of supply and demand in the industry.

The semiconductor industry is characterized by seasonality and wide fluctuations of supply and demand.  Historically, since a significant portion of our revenue is from consumer markets and international sales, our business generates stronger revenues in the first half and comparatively weaker revenues in the second half of our fiscal year. However, broad fluctuations in our business, changes in semiconductor industry and global economic conditions (including the impact of continued strong demand in the industry, the COVID-19 pandemic or trade tensions) and our acquisition activity (including our acquisition of Microsemi) have had and can have a more significant impact on our results than optimal capacity.seasonality. In periods when broad fluctuations, changes in business conditions or acquisitions occur, it is difficult to assess the impact of seasonality on our business. The semiconductor industry has had significant economic downturns, characterized by diminished product demand and production over-capacity. We have sought to reduce our exposure to this industry cyclicality by selling proprietary products, that cannot be 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.

Our business is dependent on distributors to service our end customers.

Sales to distributors accounted for approximately 48% of our net sales in fiscal 2022 and approximately 50% of our net sales in fiscal 2021. With the exception of orders placed under our Preferred Supply Program, we do not have long-term purchase agreements with our distributors, and we and our distributors may each terminate our relationship with little or no advance notice.

Future adverse conditions in the U.S. or global economies and labor markets (including the impact of the COVID-19 pandemic) or credit markets could materially impact distributor operations. Any deterioration in the financial condition, or 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, there may be an oversupply and decrease in demand for our products, which could reduce our net sales in a given period and increase inventory returns. Violations of the Foreign Corrupt Practices Act, or similar laws, by our distributors could have a material adverse impact on our business.

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:
effective new product selection;
timely completion and introduction of new product designs;
availability of skilled employees;
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. 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 others in the industry have, from time to time, experienced difficulties in transitioning to advanced
18

Table of Contents
process technologies and 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.

Business interruptions to our operations or those of our key vendors, licensees or customers 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, licensees or customers may be disrupted due to public health concerns (including outbreaks such as COVID-19), work stoppages or reduction in available labor, power loss, insufficient water, cyber attacks, computer network compromises, incidents of terrorism or security risk, political instability, telecommunications, transportation or other infrastructure failure, radioactive contamination, or fire, earthquake, floods, droughts, 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 we will avoid a significant impact on our business in the event of a business interruption. For example, in fiscal 2012 and fiscal 2013 we reduced wafer starts in both Fab 2 and Fab 4, which negatively2022, COVID-19 related restrictions adversely impacted our gross profit throughmanufacturing operations in the March 2013 quarter. We increased wafer starts modestly throughout fiscal 2014U.S., Philippines and fiscal 2015. AlthoughThailand along with our subcontractors' manufacturing operations in Malaysia, Taiwan and China. Similar challenges arose for our logistics service providers, which adversely impacted their ability to ship product to our customers. The pandemic could adversely impact our business in future periods if the impact of COVID-19 becomes more severe. In the future, local governments could require us to reduce production, cease operations at any of our facilities, or implement mandatory vaccine requirements, and we operatedcould experience constraints in fulfilling customer orders.

Additionally, operations at normal capacity levels during the last three quartersour customers and licensees may be disrupted for a number of fiscal 2015, the first two quartersreasons. In April and May 2020, we received a greater number of fiscal 2016order cancellations and the fourth quarterrequests by our customers to reschedule deliveries to future dates. Some customers requested order cancellations within our firm order window and claimed applicability of fiscal 2016,force majeure clauses. 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.

Also, Thailand has experienced periods of severe flooding in recent years. While our facilities in Thailand have continued to operate normally, there can be no assurance that 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 timely shift production to other facilities, and we may need to spend significant amounts to repair or replace our facilities and equipment.  Business interruptions would likely cause 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, cancellation of orders, or loss of customers. Although we maintain business interruption insurance, such insurance will likely not compensate us for any losses or damages, and business interruptions could significantly harm our business.

Our technology licensing business exposes us to various risks.

Our technology licensing business is based on our SuperFlash and other technologies. The success of our licensing business depends on the continued market acceptance of these technologies and on our ability to further develop such technologies and to introduce new technologies. 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 and enforce our intellectual property rights for our licensed technology;
our ability to limit our liability and indemnification obligations to licensees;
availability of development and support services to assist licensees in their design and manufacture of products;
availability of foundry licensees with sufficient capacity to support OEM production; and
market acceptance of our customers' end products.

Because our licensed technologies are complex, there may be delays from time to time in developing and enhancing such technologies. 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 reduced production levels willwhich would adversely affect the revenue that we receive. Our technology license agreements generally include a clause that indemnifies the licensee against liability and damages (including legal defense costs) arising from certain intellectual property matters. We could be maintainedexposed to substantial liability for claims or damages related to intellectual property matters or indemnification claims. Any claim could result in significant legal fees and require significant attention from our management. These issues may adversely impact the success of our licensing business and adversely affect our future periods.operating results.

Reliance on sales into governmental projects could have a material adverse effect on our results of operations.

A significant portion of the sales of Microsemi, which we acquired in May 2018, are from or are derived from government agencies or customers who sell to U.S. government agencies.  Such sales are subject to uncertainties regarding governmental spending levels, spending priorities, regulatory and policy changes.  Future sales into U.S. government projects are subject to uncertain government appropriations and national defense policies and priorities, including the budgetary process, changes in the timing and spending priorities, the impact of any past or future government shutdowns, contract terminations or renegotiations, future sequestrations, changes in regulations that we must comply with to be eligible to accept new contracts, such as the Cybersecurity Maturity Model Certification requirements and mandatory vaccine requirements, or the impact of the COVID-19 pandemic.  For example, in fiscal 2022, as a result of the COVID-19 pandemic, we experienced suspensions and stop work orders for some of our subcontracts. Although such actions have not yet had a material adverse impact on our business, there can be no assurance as to the future costs or implications of such actions. Sales into government projects are also subject to uncertainties related to monetary, regulatory, tax and trade policies implemented by current or future administrations or by the U.S. Congress.

In the past, Microsemi has experienced delays and reductions in appropriations on programs that included its products. For example, in 2018 there were two federal government shutdowns. Further delays, reductions in or terminations of government contracts or subcontracts, including those caused by any past or future shutdown of the U.S. federal government, could materially and adversely affect our operating results. If the U.S. government fails to complete its annual budget process or to provide for a continuing resolution to fund government operations, another federal government shutdown may occur, during which we may experience further delays, reductions in or terminations of government contracts or subcontracts, which could materially and adversely affect our operating results. While we generally function as a subcontractor in these type of transactions, further changes in U.S. government procurement regulations and practices, particularly surrounding initiatives to reduce costs or increase compliance obligations (such as the Cybersecurity Maturity Model Certification and mandatory vaccine requirements), may adversely impact the contracting environment, our ability to hire and retain employees, and our operating results.

The U.S. government and its contractors may terminate their contracts with us at any time. For example, in 2014, the U.S. government terminated a $75 million contract with Microsemi.  Uncertainty in government spending and termination of contracts for government related projects could have a material adverse impact on the revenue from our Microsemi acquisition.  Our contracts with U.S. governmental agencies or prime customers require us to comply with the contract terms, and governmental regulations, particularly for our facilities, systems and personnel that service such customers.  To be awarded new contracts, we may be required to meet certain levels of the Cybersecurity Maturity Model Certification that we may not meet, or choose to meet. Complying with these regulations, including audit requirements, requires that we devote significant resources to such matters in terms of training, personnel, information technology and facilities.  Any failure to comply with these requirements may result in fines and penalties, or loss of current or future business, that may materially and adversely affect our operating results.

From time to time we receive grants from governments, agencies and research organizations. If we are unable to comply with the terms of those grants, we may not be able to receive or recognize grant benefits or we may be required to repay grant benefits and recognize related charges, which would adversely affect our operating results and financial position.

From time to time, we receive economic incentive grants and allowances from European governments, agencies and research organizations targeted at increasing employment at specific locations. The subsidy grant agreements typically contain economic incentive, headcount, capital and research and development expenditures and other covenants that must be met to receive and retain grant benefits, and these programs can be subjected to periodic review by the relevant governments. Noncompliance with the conditions of the grants could result in our forfeiture of all or a portion of any future amounts to be received, as well as the repayment of all or a portion of amounts received to date.

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


We have acquired, and expect in the future to acquire, additional businesses that we believe will complement or augment our existing businesses. On April 4, 2016,In May 2018, we acquired AtmelMicrosemi, which iswas our largest and most complex acquisition ever. In addition, in August 2015, we completed our acquisitionIntegration of Micrel; in July 2014, we completed our acquisition of a controlling interest in ISSC Technologies Corp. (ISSC); in April 2014, we completed our acquisition of Supertex, Inc. (Supertex); and in August 2012, we completed our acquisition of Standard Microsystems Corporation (SMSC). The integration process for our acquisitions is complex and 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 wepolicies. We may be unable tonot realize the expected synergies and cost savings from the integration. There may be increased risk due to integrating financial reporting and internal control systems. WeIt may have difficulty in developing, manufacturingbe difficult to develop, manufacture and marketingmarket the products of a newly

acquired company, or in growinggrow 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 have been and may in the future be subject to claims from terminated employees, shareholders of Microchip or the acquired companies and other third parties related to the transaction. In particular, as a result ofin connection with our Microsemi and Atmel acquisition,acquisitions, we became involved with certain third-party claims, litigation, governmental investigations and disputes related to the Atmel business.such businesses and transactions. See "Item 3. Legal Proceedings"Note 11 to our consolidated financial statements for information regarding such claims.matters. Acquisitions may also result in charges (such as acquisition-related expenses, write-offs, restructuring charges, or future impairment of goodwill), contingent liabilities, adverse tax consequences, additional stock-basedshare-based compensation expense and other charges that adversely affect our operating results. Additionally,To fund our acquisition of Microsemi, we used a significant portion of our cash balances and incurred approximately $8.10 billion of additional debt. We may fund future acquisitions of new businesses or strategic alliances by utilizing cash, borrowings under our credit agreement,Revolving Credit Facility, raising debt, issuing shares of our common stock, or other mechanisms.


Further, if we decide to divest assets or a business, weit may encounter difficulty in findingbe difficult to find or completingcomplete divestiture opportunities or alternative exit strategies, which may include site closures, timely or on acceptable terms or in a timely manner.terms. These circumstances could delay the achievement of our strategic objectives or cause us to incur additional expenses with respect to assetsthe desired divestiture, or a business that we want to dispose of, or we may dispose of assets or a business at athe price or on terms that areof the divestiture may be less favorable than we had anticipated. Even following a divestiture or other exit strategy, we may be contractually obligated with respect tohave certain continuing obligations to former employees, customers, vendors, landlords or other third parties. We may also have continuing obligations for pre-existing liabilities related to theformer employees, assets or businesses. Such obligations may have a material adverse impact on our results of operations 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.


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

In February 2015, we amended our credit agreement to increase the revolving credit facility to $2.555 billion and we sold $1.725 billion of principal value of our 1.625% senior subordinated convertible debentures. As a result of such transactions,our acquisition activity, our goodwill and intangible assets have increased significantly in recent years and we have a substantially greater amount of debt than we had maintainedmay in the past. In August 2015,future incur impairments to goodwill or intangible assets.

When we increased our borrowings under our credit agreement to finance the approximately $430 million cashacquire a business, a substantial portion of the purchase price of our Micrelthe acquisition is allocated to goodwill and other identifiable intangible assets. The amount of the purchase price which closed on August 3, 2015. In December 2015, we exercised our increase option in our credit agreementis allocated to obtain additional revolving commitmentsgoodwill is determined by the excess of $219 million, bringing our total revolving credit facility to $2.774 billion. Atthe purchase price over the net identifiable assets acquired. As of March 31, 2016,2022, we had $1,052.0 million in outstanding borrowings under such credit agreement.goodwill of $6.67 billion and net intangible assets of $4.04 billion. In connection with the closingcompletion of our acquisition of AtmelMicrosemi in May 2018, our goodwill and intangible assets increased significantly. We review our indefinite-lived intangible assets, including goodwill, for impairment annually in the fourth fiscal quarter or whenever events or changes in circumstances indicate that the carrying amount of those assets is more likely than not impaired.  Factors that may be considered in assessing whether goodwill or intangible assets may be impaired 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 April 4, 2016,experience and to rely heavily on projections of future operating performance.  Because we increasedoperate in highly competitive environments, projections of our borrowingsfuture operating results and cash flows may vary significantly from our actual results.  No goodwill impairment charges were recorded in fiscal 2022 or fiscal 2021. In fiscal 2022, we recognized $3.0 million of intangible asset impairment charges. No intangible asset impairment charges were recorded in fiscal 2021. If in future periods, we determine that our goodwill or intangible assets are impaired, we will be required to write down these assets which would have a negative effect on our consolidated financial statements.

If we fail to maintain proper and effective internal control and remediate any future control deficiencies, our ability to produce accurate and timely financial statements could be impaired, which could harm our operating results, our ability to operate our business and our reputation with investors.

We have in the past identified a material weakness in our internal controls related to accounting for income taxes and we also identified a material weakness in our internal controls related to IT system access. Although such material weaknesses were remediated in fiscal 2020, there can be no assurance that similar control issues will not be identified in the future. If we cannot remediate future material weaknesses or significant deficiencies in a timely manner, or if we identify additional control deficiencies that individually or together constitute significant deficiencies or material weaknesses, our ability to accurately record, process, and report financial information and our ability to prepare financial statements within required time periods, could be adversely affected. Failure to maintain effective internal controls could result in violations of applicable securities laws, stock exchange listing requirements, and the covenants under our credit agreement by approximately $0.94 billiondebt agreements, subject us to finance

litigation and investigations, negatively affect investor confidence in our financial statements, and adversely impact our stock price and our ability to access capital markets.

Ensuring that we have adequate internal financial and accounting controls and procedures so that we can produce accurate financial statements on a portiontimely basis is a costly and time-consuming effort that needs to be re-evaluated frequently. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with U.S. GAAP. We are required to comply with Section 404 of the purchaseSarbanes-Oxley Act of 2002 which requires an annual management assessment of the effectiveness of our internal control over financial reporting and a report by our independent auditors. In addition to the identified material weaknesses related to accounting for income taxes and to IT system access, which were remediated as of March 31, 2020, we have from time to time identified other significant deficiencies. If we fail to remediate any future material weaknesses or significant deficiencies or to maintain proper and effective internal control over financial reporting in the future, our ability to produce accurate and timely financial statements could be impaired, which could harm our operating results, harm our ability to operate our business and reduce the trading price of our stock.

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 require that we implement practices that are more stringent than those required by applicable laws with respect to labor requirements, the materials contained in our products, energy efficiency, environmental matters or other items. To comply with such acquisition.requirements, we also require our suppliers to adopt such practices. Our maintenancesuppliers may in the future refuse to implement these practices, or may charge us more for complying with them. If certain of substantial levelsour suppliers refuse to implement the practices, we may be forced to source from alternate suppliers. The cost to implement such practices may cause us to incur higher costs and reduce our profitability, and if we do not implement such practices, such customers may disqualify us as a supplier, resulting in decreased revenue opportunities. Developing, enforcing, and auditing customer-requested practices at our own sites and in our supply chain will increase our costs and may require more personnel.

We must attract and retain qualified personnel to be successful, and competition for qualified personnel has intensified.

We must attract and retain qualified personnel to be successful, and competition for qualified personnel has intensified in recent periods in our industry due to high demand for skilled employees. Availability of debtlabor is currently constrained in certain geographic markets in which we operate due to the tight and competitive labor market across our industry. Competition for available labor has intensified for a variety of reasons, including the increase in work-from home arrangements brought about by COVID-19, and the wage inflation in our industry.

Our ability to attract and retain skilled employees such as management, technical, marketing, sales, research and development, manufacturing, and operational personnel is critical to our business. We rely on a direct labor force at our manufacturing facilities. Any inability to maintain our labor force at our facilities may disrupt our operations, delay production, shipments and revenue and result in us being unable to timely satisfy customer demand, and ultimately could materially and adversely affect our ability to take advantage of corporate opportunities and could adversely affect ourbusiness, financial condition and results of operations. Our inability to attract and retain hardware and software engineers and sales and marketing personnel, could delay the development and introduction of, and harm our ability to sell, our products. We may need or desire to refinance all or a portionhave no employment agreements with any member of our loans undersenior management team, and it is possible that they could leave with little or no notice, which could make it more difficult for us to execute our credit agreement,planned business strategy. Our inability to retain, attract or motivate personnel could have a material adverse effect on our business, financial condition and results of operations.


debenturesThe 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 coverage related to many different types of risk; however, we self-insure for some potentially significant risks and obligations, because we believe that it is more cost effective for us to self-insure than to pay the high premium costs. The risks and exposures that we self-insure include, but are not limited to, employee health matters, certain property matters, product defects, cybersecurity matters, employment risks, environmental matters, political risks, and intellectual property matters. Should there be a loss or adverse judgment in an area for which we are self-insured, then our financial condition, results of operations and liquidity may be materially adversely affected.

Risks Related to Cybersecurity, Privacy, Intellectual Property, and Litigation

We continue to be the target of attacks on our IT systems. Interruptions in and unauthorized access to our IT systems, or improper handling of data, could adversely affect our business.

We rely on the uninterrupted operation of complex IT 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 business, operations, supply chain, sales and operating results.  Such disruption could result in an unauthorized release of our, our suppliers’ or our customers’ intellectual property or confidential, proprietary or sensitive information, or the release of personal data. Any release of such information or data could harm our business or competitive position, result in a loss of customer confidence, and cause us to incur significant costs to remedy the damages. In addition, any release of such information or data or the failure to properly manage the collection, handling, transfer or disposal of such information may result in regulatory inquiries or penalties, enforcement actions, remediation obligations, claims for damages, litigation, and other future indebtednesssanctions.

We have experienced verifiable attacks on our IT systems and data, including network compromises, attempts to breach our security measures and attempts to introduce malicious software into our IT systems. For example, in fiscal 2019, we learned of an ongoing compromise of our computer networks by what is believed to be sophisticated hackers. We engaged outside legal counsel and a leading forensic investigatory firm with experience in such matters. We took steps to identify malicious activity on our network including a compromise of our network and, in May 2019, we began implementing a containment plan. We routinely evaluate the effectiveness of the containment mechanisms that were implemented and continue to implement additional measures. We have analyzed the information that was compromised. We do not believe that this IT system compromise has had a material adverse effect on our business or resulted in any material damage to us. As a result of the IT system compromise, our management, including our chief executive officer and our chief financial officer, concluded that our internal controls related to IT system access were not effective resulting in a material weakness in our internal controls for fiscal 2019. Although this material weakness in our internal control was remediated in fiscal 2020, there can be no assurance that similar control issues will not be identified in future periods.

Due to the types of products we will be ablesell and the significant amount of sales we make to refinance any of our indebtedness on commercially reasonable terms, if at all.

Wegovernment agencies or customers whose principal sales 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,U.S. government agencies, 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;
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, mixed signal and timing products have remained relatively constant, while average selling prices of our memory and non-proprietary analog, interface, mixed signal and timing 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 inattacks on our memoryIT systems and non-proprietary analog, interface, mixed signaldata, including attempts to breach our security, network compromises and timing products. Weattempts to introduce malicious software into our IT systems. Were any future attacks to be successful, we may be unableunaware of the incident, its magnitude, or its effects until significant harm is done. In recent years, we have regularly implemented improvements to maintain average selling pricesour protective measures which include, but are not limited to, implementation of the following: firewalls, endpoint intrusion detection and response software, regular patches, log monitors, event correlation tools, network segmentation, routine backups with offsite retention of storage media, system audits, dual factor identification, data partitioning, privileged account segregation and monitoring, routine password modifications, and an enhanced information security program including training classes and phishing exercises for our products asemployees and contractors with system access, along with tabletop exercises conducted by information security personnel. As a result of the material weakness in our internal controls resulting from the IT systems compromise in fiscal 2019, we have taken remediation actions and implemented additional controls and we are continuing to take actions to attempt to address evolving threats. However, recent system improvements have not been fully effective in preventing attacks on our IT systems and data, including breaches of our security measures, and there can be no assurance that any future system improvements will be effective in preventing future cyber-attacks or disruptions or limiting the damage from any future cyber-attacks or disruptions. Such system improvements have resulted in increased pricing pressure in the future, which could adversely impact our operating results.




We are dependent on wafer foundries and other contractorscosts to perform key manufacturing functions for us and any future improvements, attacks or disruptions could result in additional costs related to rebuilding our licensees of our SuperFlash andinternal systems, defending litigation, complaints or other technologies also rely on foundries andclaims, providing notices to regulatory agencies or other contractors.

We rely on outside wafer foundries for a significant portion of our wafer fabrication needs. Specifically, during each of fiscal 2016 and fiscal 2015, approximately 39% of our net sales came from products that were produced at outside wafer foundries. 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 acquisitions of SMSC in August 2012, Supertex in April 2014 and ISSC in July 2014. 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 wereresponding to experience financial, operationalregulatory actions, or production difficultiespaying damages. Such attacks 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 the countries in which such contractors are located 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 on terms favorable to us, or at all. 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, our use of subcontractors increases the risks of potential misappropriation of our intellectual property.

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

Our operating results are 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, changes in semiconductor industry and global economic conditions and our acquisition activity can have a more significant impact on our results than seasonality. As a result, in periods when these broad fluctuations, changes in business conditions or acquisitions occur, it is difficult to assess the impact of seasonal factors on our business. The semiconductor 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.

Our business is dependent on selling through distributors.

Sales through distributors accounted for approximately 53% of our net sales in fiscal 2016 and approximately 51% of our net sales in fiscal 2015. 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 partnersdisruptions could have a material adverse impact on our business.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 portions of our and our customers' 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 breach or 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.

Our success dependsfailure to comply with federal, state, or international privacy and data protection laws and regulations may materially adversely affect our business, results of operations and financial condition.

We are subject to numerous laws and regulations in the U.S. and internationally regarding privacy and data protection such as the European Union’s (EU) General Data Protection Regulation (GDPR), the U.K. equivalent to the GDPR, the California Consumer Privacy Act, and the California Privacy Rights Act. The scope of these laws and regulations is rapidly evolving, subject to differing interpretations, and may be inconsistent among jurisdictions. Some of these laws create a broad definition of personal information, establish data privacy rights, impose data breach notification requirements, and create potentially severe statutory damages frameworks and private rights of action for certain data breaches. Some of the laws and regulations also place restrictions on our ability to introduce new productscollect, store, use, transmit and process personal information and other data across our business. For example, the GDPR restricts the ability of companies to transfer personal data from the European Economic Area (EEA) to the U.S. and other countries. Further, such laws and regulations have resulted and will continue to result in significantly greater compliance burdens and costs for companies such as us that have employees, customers, and operations in the EEA.

In order to comply with the GDPR, we have relied mainly on the European Commission’s Standard Contractual Clauses (SCCs), for transfers of personal information from the EEA to the U.S. or other countries. However, the Court of Justice of the EU in a timely basis.

Our future operating results depend onJuly 2020 decision (Schrems II) invalidated the EU-U.S. Privacy Shield Framework, and also called for stricter conditions in the use of the SCCs. Following the Schrems II decision, certain data protection authorities in the EU have issued statements advising companies within their jurisdiction not to transfer personal data to the U.S. under the SCCs. At present, there are few, if any, viable alternatives to the SCCs. If we are unable to implement sufficient safeguards to ensure that our transfers of personal information from the EEA are lawful, we may face increased exposure to regulatory actions and substantial fines and injunctions against processing personal information from the EEA. The loss of our ability to lawfully transfer personal data out of the EEA may cause reluctance or refusal by European customers to communicate with us as they are currently, and we may be required to increase our data processing capabilities in the EEA at significant expense. Additionally, other countries outside of the EEA have passed or are considering passing laws requiring local data residency which could increase the cost and complexity of providing our products in those jurisdictions.

Furthermore, the GDPR and the U.K. equivalent of the GDPR expose us to two parallel data protection regimes in Europe, each of which potentially authorizes fines and enforcement actions for certain violations. Substantial fines may be imposed for breaches of data protection requirements, which can be up to 4% of a company’s worldwide revenue or 20 million Euros, whichever is greater. Although the U.K. data protection regime currently permits data transfers from the U.K. to the EEA and other third countries, covered by a European Commission 'adequacy decision' through the continued use of SCCs and binding corporate rules, these laws and regulations are subject to change, and any such changes could have adverse implications for our transfer of personal data from the U.K. to the EEA and other third countries.

While we plan to continue to undertake efforts to conform to current regulatory obligations and evolving best practices, such efforts may be unsuccessful or result in significant costs. We may also experience reluctance, or refusal by European or multi-national customers to continue to provide us with personal data due to the potential risk exposure of personal data transfers and the current data protection obligations imposed on them by applicable data protection laws or by certain data protection authorities. These and any other data privacy laws and their interpretations continue to develop and timely introduce newtheir uncertainty and inconsistency may increase the cost of compliance, cause compliance challenges, restrict our ability to offer products that compete effectively onin certain locations in 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 literaturesame way 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 timebeen, potentially adversely affect certain third-party service providers, or subject us 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,sanctions by data protection regulators, all of 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 and other technologies. The success of our licensing business depends on the continued market acceptance of these technologies and on our ability to further develop and enhance such technologies 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 and enforce 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 licensed technologies are complex, there may be delays from time to time in developing and enhancing such technologies. 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.business, financial condition and results of operations.

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, investigations or claims.


We are currently, and in the future may be, involved in legal proceedings, investigations or claims regarding patent infringement, other intellectual property rights, product failures, our Microsemi acquisition, contracts and other matters. As is typical in the semiconductor industry, we receive notifications from third parties from time to time who believe that we owe them indemnification or other obligations related to claims made against us, our direct or indirect customers, or our licensees. These legal proceedings and claims, even if meritless, have in the past and could in the future result in substantial costs to us and divert our resources.us. If we are not ableunable to resolve a claim,or settle a matter, obtain necessary licenses on commercially reasonable terms, reengineer our products or processes to avoid infringement, provide a cost-effective remedy, or successfully prosecute or defend our position, we could incur uninsured liability in any of them, be required to take an appropriatea 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.


24

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, economic damage or environmental exposures related to manufacturing, a product's nonconformance to our specifications or our customer’s 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 or unpaid receivables;
customer imposed fines or penalties for failure to meet contractual requirements; and
a requirement to pay damages or penalties.


Because the systems into which our products are integrated have a higher cost of goods than the products we sell, the expenses and damages we are asked to pay may be significantly higher than the salesrevenue and profits we received from the products involved.received. 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 paymentsPayments 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, defense, safety, security, and medical, where failure of the systems in which our products are integratedapplication 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.


Our contractual relationships with our customers expose us to risks and liabilities.

With the exception of orders placed under our Preferred Supply Program, we do not typically enter into long-term contracts with our non-distributor customers, and therefore we cannot be certain about future order levels from our customers. When we do enter into customer contracts (other than under our Preferred Supply Program), the contract is generally cancelable based on standard terms and conditions. Under our Preferred Supply Program, customers may cancel contracts in the event of price increases. While we had approximately 124,000 customers, and our ten largest direct customers accounted for approximately 12% of our total revenue in fiscal 2022, and five of our top ten direct customers are contract manufacturers that perform manufacturing services for many customers, cancellation of customer contracts could have an adverse impact on our revenue and profits. For example, due to uncertainty related to the COVID-19 pandemic, we experienced an increase in order cancellations and requests to reschedule deliveries to future dates in the first quarter of fiscal 2021.

Certain customer contracts differ from our standard terms of sale. For some of the markets that we sell into, such as the automotive and personal computer markets, our customers may have negotiating leverage over us as a result of their market size. For example, under certain contracts we have committed to supply products on scheduled delivery dates, or extended our obligations for liabilities such as warranties or indemnification for quality issues or intellectual property infringement. If we are unable to supply the customer as contractually required, the customer may incur additional production costs, lost revenues due to delays in their manufacturing schedule, or quality-related issues. We may be liable for costs and damages associated with customer claims, and we may be obligated to defend the customer against claims of intellectual property infringement and pay associated legal fees. While we try to minimize the number of contracts which contain such provisions, manage the risks of such liabilities, and set caps on our liability exposure, sometimes we are unable 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, and may in the future, have to agree to uncapped liability for such items as intellectual property infringement or product failure. This exposes us to risk of liability far exceeding the purchase price of the products sold under such contracts, the lifetime revenues we receive under such contracts, or potential consequential damages. Further, where we do not have negotiated customer contracts, our customer's order terms may govern the transaction and contain terms unfavorable to us. These risks could result in a material adverse impact on our results of operations and financial condition.

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,
25

and patents may not be issued from currently pending or future applications. In addition, our existing and new patents, trademarks and copyrights that issueare issued 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 partythird-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.successful.


Risks Related to Taxation, Laws and Regulations

Our operatingreported financial results may be adversely impacted if economic conditions impact the financial viability of our licensees, customers, distributors,affected by new accounting pronouncements or suppliers.changes in existing accounting standards and practices.

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 substantialA significant portion of our net sales. During fiscal 2016, approximately 84%sales require export and import activities. Our U.S.-manufactured products or products based on U.S. technology are subject to laws and regulations on international trade, including but not limited to the Foreign Corrupt Practices Act, EARs, International Traffic in Arms Regulations and trade sanctions against embargoed countries and denied entities, including those administered by the U.S. Department of our net sales were made to foreign customers, including 30% in China. During fiscal 2015, approximately 84%the Treasury, Office of our net sales were made to foreign customers, including 28% 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 competitorsForeign Assets Control. Licenses or license exceptions are aggressively seeking to increase their market share. Increased competition or economic weakness in the China market may make it difficult for us to achieve our desired sales volumes in China. In particular, economic conditions in China remain uncertain and we are unable to predict whether such uncertainty will continue or worsen in future periods.

We deliver products to our European customers through our facilities in England. The UK’s EU referendum on June 23, 2016 (called "Brexit" in the press) is to determine whether the UK will leave the EU. If the UK does leave the EU, we may lose our ability to import and export products tax-free throughout Europe. As a result, it may increase the costs to Microchiprequired for the import and saleshipment of our products to our customers,certain countries. Our inability to timely obtain a license, for any reason, including a delay in license processing due to a federal government shutdown like that which may resultoccurred in 2018, could cause a decreasedelay in sales to certain of our customers. In order to avoid these costs, we may have to consider alternate methods for delivering product into Europe. In implementing these changes, we may experience a disruption in operations or product shipments.

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,scheduled shipments which has experienced periods of political instability in the past. Substantially all of our finished goods inventory is maintained in Thailand. From time to time, Thailand has also experienced periods of severe flooding. There can be no assurance that any future flooding or political instability in Thailand would notcould have a material adverse impact on our operations. We use various foundriesrevenue within the quarter of a shutdown, and other foreign contractors forin following quarters depending on the extent that license processing is delayed. Further, determination by a significant portiongovernment that we have failed to comply with trade regulations or anti-bribery regulations can result in penalties which may include denial of export privileges, fines, penalties, and seizure of products, any of which could have a material adverse effect on our business, sales and earnings. A change in laws and regulations could restrict our ability to transfer product to previously permitted countries, customers, distributors or others. For example, in February 2022, the U.S. began implementing widescale sanctions against Russia due to Russia's invasion of the Ukraine. Sanctions against Belarus and certain Ukraine regions were later implemented. Because the actions by Russia against the Ukraine are in conflict with our Guiding Values, Microchip chose to cease shipments into Russia and Belarus, and we will continue to comply with applicable U.S. sanctions regarding Ukraine. While sales of our assemblyproducts into these regions, and testing and wafer fabrication requirements.

Our reliance on foreign operations, foreign suppliers, maintenance of substantially all of our finished goods inventoryto customers that sell into these regions, have been negatively impacted, at foreign locations and significant foreign sales exposes us to foreign political and economic risks, including, butthis time, we have not limited to:

political, social and economic instability;
economic uncertainty in the worldwide markets served by us;
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;
currency fluctuations and foreign exchange regulations;
difficulties in staffing and managing international operations;
employment regulations;
disruptions in international transport or delivery;
public health conditions;
difficulties in collecting receivables and longer payment cycles; 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.


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 93,000 customers and our ten largest direct customers made up approximately 10% of our total revenue for fiscal 2016, cancellation of customer contracts could have anexperienced a material adverse impact on our revenuerevenue. An additional example occurred in April 2018, when the U.S. Commerce Department banned U.S. companies from selling products or transferring technology to ZTE, a Chinese company, and profits.

We have entered into contracts with certain customers that differsubsidiaries. This ban was lifted in July 2018. In fiscal 2020, when the U.S. Commerce Department banned U.S. companies from our standard terms of sale. Further,selling products or transferring technology to certain Chinese companies, including Huawei and certain subsidiaries. In fiscal 2020, the U.S. Federal Acquisition Regulation prohibited U.S. governmental agencies from buying equipment using covered telecommunications equipment as a resultsubstantial component or critical technology where the technology came from certain Chinese companies. In July 2020, this was expanded to prohibit U.S. governmental agencies from entering into a contract with any company that uses covered telecommunications equipment whether or not the Chinese technology is related to the procurement. Effective June 2020, amendments to the EAR regarding prohibitions of sales of items with a “military end use” into China, Russia, and Venezuela, and Belarus effective March 2021, and elimination of an EAR License Exception, apply to more of our acquisitions, we may inherit certain customer contracts that differ from our standard terms of sale. For severalproducts than the previous regulations. Any of the significant markets that we sell into, such as the automotive and personal computer markets,foregoing changes could adversely impact 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 productionoperational costs lost revenues due to subsequent delaysthe administrative impacts of complying with these regulations, and may limit those with whom we conduct business. Any one or more of these sanctions, future sanctions, a change in their own manufacturing schedule,laws or quality-related issues. We may be liable for the customer's costs, expenses and damages associated with their claims and we may be obligatedregulations, or a prohibition on shipment of our products or transfer of our technology to defend the customer against claims of intellectual property infringement and pay the associated legal fees. While we try to minimize the number of contracts which contain such provisions, manage the risks underlying such liabilities, and set capssignificant customers could have a material adverse effect on our liability exposure, sometimes we arebusiness, financial condition and results of operations.

The U.S. and other countries have levied tariffs and taxes on certain goods, implemented trade restrictions, and introduced national security protection policies. Trade tensions between the U.S. and China, which escalated in 2018, have
26

continued and include the U.S. increasing tariffs on Chinese origin goods and China increasing tariffs on U.S. origin goods. We took steps to mitigate the costs of these tariffs on our business by making adjustments in operations and supply. Although these tariff increases did not 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, product failure, 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 operating costs in fiscal 2019 or fiscal 2020, they did reduce demand for our products during fiscal 2019 and fiscal 2020. Increased tariffs on our customers' products could adversely impact their sales, and increased tariffs on our products in comparison to those of our competitors could each result in lower demand for our products.

Further changes in trade or national security protection policy, tariffs, additional taxes, restrictions on exports or other trade barriers, may limit our ability to produce products, increase our selling and/or manufacturing costs, decrease margins, reduce the competitiveness of our products, or reduce our ability to sell products, which could have a material adverse effect on our business, results of operations or financial conditions.

The outcome of future examinations of our income tax returns could have an adverse effect on our results of operations.

We are subject to examination of our U.S. and certain foreign income tax returns for fiscal 2007 and later. We regularly assess the likelihood of adverse outcomes of these examinations to determine the adequacy of our provision for income taxes and have reserved for potential adjustments that may result from current or future examinations. There can be no assurance that the final determination of any of these or any future examinations will not have an adverse effect on our effective tax rates, financial position and results of operations.

Exposure to greater than anticipated income tax liabilities, changes in tax rules and regulations, changes in the interpretation of tax rules and regulations, or unfavorable assessments from tax audits could affect our effective tax rates, financial condition and results of operations.

We are a U.S.-based multinational company subject to tax in many U.S. and foreign jurisdictions. Our income tax obligations could be affected by many factors, including changes to our operating structure, intercompany arrangements and tax planning strategies.

Our income tax expense is computed based on tax rates at the time of the respective financial period. Our future effective tax rates, financial condition and results from operations could be unfavorably affected by changes in the tax rates in jurisdictions where our income is earned, by changes in the tax rules and regulations or the interpretation of tax rules and regulations in the jurisdictions in which we do business or by changes in the valuation of our deferred tax assets.

The Organization for Economic Cooperation and Development has been working on a Base Erosion and Profit Shifting Project and is expected to continue to issue guidelines and proposals that may change aspects of the existing framework under which our tax obligations are determined in many of the countries where we do business. Similarly, the European Commission and several countries have issued proposals that would change aspects of the current tax framework under which we are taxed. These proposals include changes to the existing income tax framework, possibilities of a global minimum tax, and proposals to change or impose new types of non-income taxes, including taxes based on a percentage of revenue.

Our business, financial condition and operating results may be adversely impacted by policies implemented globally by the current or future administrations.

The current administration in the U.S. and administrations in other global jurisdictions in which we operate, have indicated support for significant legislative and policy changes in areas including but not limited to tax, trade, labor, and the environment. If implemented, these changes could increase our effective tax rate, and increase our selling and/or manufacturing costs, which could have a material adverse effect on our business, results of operations or financial conditions. Changes in tax policy, trade regulations or other matters, and any uncertainty surrounding the scope or timing of such changes, could negatively impact the stock market, and reduce the trading price of our stock. For example, in February 2022, the U.S. began implementing widescale sanctions against Russia due to Russia's invasion of the Ukraine. Sanctions against Belarus and certain Ukraine regions were later implemented. Because the actions by Russia against the Ukraine are in conflict with our Guiding Values, Microchip chose to cease shipments into Russia and Belarus, and we will continue to comply with applicable U.S. sanctions regarding Ukraine. While sales of our products into these regions, and to customers that sell into these regions, have been negatively impacted, at this time, we have not experienced a material adverse impact on our revenue. Retaliatory acts by Russia in response to the sanctions could include cyber attacks, sanctions, or other actions that could disrupt the economy. As a result of the foregoing risks or similar risks, the imposition of sanctions could have a material adverse effect on our business, results of operations or financial condition.

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

We must attractcomply with federal, state, local and retain qualified personnelforeign governmental regulations related to be successful,the use, storage, discharge and competitiondisposal of hazardous substances used in our products and manufacturing processes. Our failure to comply, or the failure of entities that we have acquired over time to have complied, with regulations could result in significant fines, liability for qualified personnel can be intense.

clean-up, suspension of production, cessation of operations or future liabilities. Such regulations have required us in the past, and could require us in the future, to incur significant expenses to comply with such regulations. Our success depends uponfailure to control the efforts and abilitiesuse of, or adequately restrict the discharge of, hazardous substances could impact the health of our senior management, engineering, manufacturingemployees 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 logistics, or require us to incur other personnel. The competitionsignificant costs and expenses. Environmental laws continue to expand with a focus on reducing or eliminating hazardous substances in electronic products and shipping materials. Future environmental regulations could require us to reengineer certain of our existing products and may make it more expensive for qualified engineeringus to manufacture, sell and management personnel canship our products. In addition, the number and complexity of laws focused on the energy efficiency of electronic products, the recycling of electronic products, and the reduction in the amount and the recycling of packing materials have expanded significantly. It may be intense.difficult for us to timely comply with these laws and we may have insufficient quantities of compliant products to meet customers' needs, thereby adversely impacting our sales and profitability. We may be unsuccessful in retaininghave to write off inventory if we hold unsaleable inventory as a result of changes to regulations. We expect these risks to continue. These requirements may increase our existing key personnel or in attractingown costs, as well as those passed on to us by our supply chain.

Climate change regulations and retaining additional key personnelsustained adverse climate change pose risks 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 lossresults of operations.

Climate change regulations or any inability to attract personnel, even if not key personnel, if experienced in sufficient numbers could harm our business. Wevoluntary actions we may have no employment agreements with any membertaken as part of our senior management team. Environmental, Social, and Governance initiatives could require us to limit emissions, change manufacturing processes, substitute materials which may cost more or be less available, fund offset projects, obtain new permits or undertake other costly activities. Failure to obtain required permits could result in fines, suspension or cessation of production. Restrictions on emissions could result in significant costs such as higher energy costs, carbon taxes, and emission cap and trade programs. The cost of compliance with such regulations could restrict our manufacturing operations, increase our costs, and have an adverse effect on our operating results.


Business interruptionsThe SEC has recently proposed a rule entitled Enhancement and Standardization of Climate-Related Disclosures for Investors. While the proposed rule is not yet in effect and is subject to change as a result of the SEC comment process, if it were to go in effect in its current form, we would incur significant additional costs of compliance due to the need for expanded data collection, analysis, and certification. Further, certain elements of the proposed rule, such as mandatory third-party verification of emissions, may be difficult to comply with in the proposed required timeframe as there may be an insufficient number of qualified third-party verification entities to meet demand.

Sustained adverse change in climate could have a direct adverse economic impact on us, such as utility shortages, and higher costs of utilities. Certain of our operations are located in arid or the operations oftropical regions, which some experts believe may become vulnerable to fires, storms, severe floods and droughts. While our key vendors, subcontractors, licensees or customers, whether duebusiness recovery plans are intended to allow us to recover from natural disasters or other disruptive events, our plans may not protect us from all events. 

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

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, in August 2012, the SEC released investigation, and disclosure requirements regarding the use of "conflict" minerals mined from the Democratic Republic of Congo and adjoining countries. We filed a Form SD with the SEC regarding such matters on May 28, 2021. Other countries are considering similar regulations. If we cannot certify that our supply chain is free from the risk of irresponsible sourcing, customers may demand that we change the sourcing of materials used in the manufacture of our products, even if the costs for compliant materials significantly increases or availability is limited.  If we change materials or suppliers, there will likely be costs associated with qualifying new suppliers and production capacity and quality could be negatively impacted.  Our relationships with customers and suppliers may be adversely affected if we are unable to certify that our products are free from the risk of irresponsible sourcing. We have incurred, and expect in the future to incur, additional costs associated with complying with these disclosure requirements, such as costs related to determining the source of any conflict minerals used in our products.  We may be unable to satisfy customers who require that all of the components of our products be certified as conflict free in a materially different manner than advocated by the Responsible Minerals Initiative or the Dodd-Frank Wall Street Reform and Consumer Protection Act.  If we are unable to meet customer requirements, customers may disqualify us as a supplier and we may have to write off inventory if it cannot be sold.

28

In addition to concerns over “conflict” minerals mined from the Democratic Republic of Congo, our customers may require that other minerals and substances used within our supply chain be evaluated and reported on. An increase in reporting obligations will increase associated operating costs. This could have negative effects on our overall operating profits.

A requirement to fund our foreign pension plans could negatively affect our cash position and operating capital.

In connection with our acquisitions of Microsemi and Atmel, we assumed pension plans that cover certain French and German employees. Most of these plans are unfunded in compliance with statutory requirements, and we have no immediate intention of funding these plans. The projected benefit obligation totaled $74.6 million at March 31, 2022. Benefits are paid when amounts become due. We expect to pay approximately $1.6 million in fiscal 2023 for benefits earned. Should regulations require funding of these plans in the future, it could negatively affect our cash position and operating capital.

Risks Related to Capitalization and Financial Markets

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 recent 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:
global economic and financial uncertainty due to the COVID-19 pandemic or other factors;
quarterly variations in our operating results or the operating results of other technology companies;
changes in our financial guidance or our failure to meet such guidance;
changes in analysts' estimates of our financial performance or buy/sell recommendations;
general conditions in the semiconductor industry;
the amount and timing of repurchases of shares of our common stock;
our ability to realize the expected benefits of our completed or future acquisitions; and
actual or anticipated announcements of technical innovations or new products by us or our competitors.

In addition, the stock market has recently and in the past experienced significant price and volume fluctuations that have affected the market prices for many companies and that often have been unrelated to their operating performance. These broad market fluctuations and other factors have harmed and may harm the market price of our business.common stock. The foregoing factors could also cause the market price of our Convertible Debt to decline or fluctuate substantially.


OperationsThe amount and timing of our share repurchases may fluctuate in response to a variety of factors.

The amount, timing, and execution of repurchases of shares of our common stock may fluctuate based on the share price of our common stock, general business and market conditions, tax regulations impacting share repurchases and other factors including our operating results, level of cash flow, capital expenditures and dividend payments. Although our Board of Directors has authorized share repurchases of up to $4.00 billion, the authorization does not obligate us to acquire any particular amount of shares. We cannot guarantee that our share repurchase authorization will be fully consummated or that it will enhance long-term shareholder value. The repurchase authorization may be suspended or discontinued at any time at our discretion and may affect the trading price of our facilities, atcommon stock and increase volatility.

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

As of March 31, 2022, the facilities of anyprincipal amount of our wafer fabrication or assembly and test subcontractors, or at anyoutstanding indebtedness was $7.84 billion. As a result of our significant vendorsacquisition of Microsemi, we have substantially more debt than we had prior to May 2018. At March 31, 2022, we had $1.40 billion in outstanding borrowings under our Revolving Credit Facility which provides up to $2.75 billion of revolving loan commitments that terminate in 2026. At March 31, 2022, we had $5.60 billion in aggregate principal amount of Senior Notes and $838.1 million in aggregate principal of Convertible Debt outstanding.

Our maintenance of substantial levels of debt could adversely affect our ability to take advantage of opportunities and could adversely affect our financial condition and results of operations. We may need or customers may be disrupted for reasons beyonddesire to refinance our control. These reasons may include work stoppages, power loss, incidents of terrorismcurrent 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. While our facilities in Thailand have continued to operate normally,future debt and there can be no assurance that any future flooding in Thailand would not havewe will be able to do so on reasonable terms, if at all.

Servicing our debt requires a material adverse impact on our operations. If operations at anysignificant amount of our facilities, or our subcontractors' facilities are interrupted,cash, we may not be ablehave sufficient cash to shift productionfund payments and adverse changes in our credit ratings could increase our borrowing costs and adversely affect our ability to access the debt markets.

Our ability to make scheduled payments of principal, interest, or to refinance our indebtedness, including our outstanding Convertible Debt and Senior Notes, depends on our future performance, which is subject to economic, competitive and other facilities on a timely basis,factors including those related to the COVID-19 pandemic. Our business may not continue to generate sufficient cash flow to service our debt and to fund capital expenditures, dividend payments, share repurchases or acquisitions. If we are unable to generate such cash flow, we may needbe required to spend significant amountsundertake alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on onerous or highly dilutive terms. Our ability to repair or replacerefinance our facilitiesindebtedness will depend on the capital markets and equipment.  Ifour financial condition at such time. Our senior secured notes are rated by certain major credit rating agencies. These credit ratings impact our cost of borrowing and our ability to access the capital markets and are based on our financial performance and financial metrics including debt levels. There is no assurance that we experienced business interruptions, we would likely experience delays in shipmentswill maintain our current credit ratings. A downgrade of products to our customers and alternate sources for production may be unavailable on acceptable terms. Thiscredit rating by a major credit rating agency could result in reduced revenuesincreased borrowing costs and profitscould adversely affect our ability to access the debt markets to refinance our existing debt or finance future debt.

Conversion of our Convertible Debt will dilute the ownership interest of our existing stockholders.

The conversion of some or all of our outstanding Convertible Debt will dilute the ownership interest of our existing stockholders to the extent we deliver common stock upon conversion of such debt. Following our irrevocable settlement election made on April 1, 2022, upon conversion, we are required to satisfy our conversion obligation with respect to such converted Convertible Debt by delivering cash equal to the principal amount of such converted Convertible Debt and the cancellationcash and shares of orderscommon stock 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.



Additionally, operationscombination, at our customers and licensees mayoption, with respect to any conversion value in excess thereof (i.e., the conversion spread). There would be disruptedno adjustment to the numerator in the net income per common share computation for a numberthe cash settled portion of reasons. In the eventConvertible Debt as that portion of customer disruptions,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 productsConvertible Debt could adversely affect prevailing market prices of our common stock. In addition, the existence of the Convertible Debt may decline andencourage short selling by market participants because the conversion of the Convertible Debt could be used to satisfy short positions, or anticipated conversion of the Convertible Debt into shares of our revenue, profitability and financial conditioncommon stock could suffer. Likewise, ifdepress the price of 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.common stock.


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 the value of a foreignnon-U.S. currency significantly declines in value in relationrelative to the U.S. dollar, customers transacting in that foreign currency may find it more difficultbe unable 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 isdeclines significantly declining in relationrelative to the British pound, Euro, and Thai baht and Taiwan dollar, the operational costs in our European and Thailand subsidiaries are adversely affected. Over the past several months, the U.S. dollar has declined slightly against the Euro and other major currencies.  Although our business has not been materially adversely impacted by such changerecent changes in the value of the U.S. dollar, there can be no assurance as to the future impact that any weakness or strength in the strength of theU.S. dollar will have on our business or results of operations.


Interruptions in our information technology systems, or improper handling of data, 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 any such disruptions or security breaches. Additionally, any 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 attacks or disruptions. Any such attack or disruption could result in additional costs related to rebuilding of our internal systems, defending litigation, responding to regulatory actions, or paying damages. Such attacks or disruptions 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, environmental matters, 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 the 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, energy efficiency measures, and supplier practices associated with sourcing and manufacturing. These requirements may increase our own costs, as well as those passed on to us by our supply chain.

Customer demands for us to implement business practices that are more stringent than existing 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.

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 of 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 adverse impact on our financial position and results of operations.

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 investigation, disclosure and reporting requirements regarding the use of "conflict" minerals mined from the Democratic Republic of Congo and adjoining countries and which are necessary to the functionality or production of products.  We filed a report on Form SD with the SEC regarding such matters on June 1, 2015. Other countries are considering similar regulations.  If we cannot certify that we are using conflict-free minerals, customers may demand that we change the sourcing of minerals and other materials used in the manufacture of our products, even if the costs for compliant minerals and materials significantly increases and availability is limited.  If we make changes to materials or suppliers, there will likely be costs associated with qualifying new suppliers and production capacity and quality could be negatively impacted.  Our relationships with customers and suppliers may be adversely affected if we are unable to certify that our products are "conflict-free." We have incurred, and

expect in the future to incur, 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.  We may also encounter challenges to satisfy those customers who require that all of the components of our products be certified as conflict free in a materially different manner than advocated by the Conflict Free Smelter Initiative or the Dodd-Frank Wall Street Reform and Consumer Protection Act.  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), International Traffic in Arms Regulations (ITAR) 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. We are currently under IRS audit for fiscal 2011 and fiscal 2012.  We are subject to certain income tax examinations in foreign jurisdictions for fiscal 2008 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.

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 our financial guidance or our failure to meet such guidance;
changes in analysts' estimates of our financial performance or buy/sell recommendations;
any acquisitions we pursue or complete (including our recent acquisition of Atmel); 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.

As a result of our acquisition activity, our goodwill and intangible assets have increased significantly in recent years and we may in the future incur impairments to goodwill or long-lived assets.

When we acquire a business, a substantial portion of the purchase price of the acquisition is allocated to goodwill and other identifiable intangible assets. The amount of the purchase price which is allocated to goodwill and other intangible assets is determined by the excess of the purchase price over the net identifiable assets acquired. As of March 31, 2016, we had goodwill of $1,012.7 million and net intangible assets of $606.3 million. 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 2016 or fiscal 2015.  However, if in future periods, we determine that our long-lived assets, including goodwill or intangible assets, are impaired, we will be required to write down these assets which would have a negative effect on our consolidated financial statements.  

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.

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. In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09 - Revenue from Contracts with Customers (Topic 606), which will supersede nearly all existing revenue 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 currently evaluating the impact that the adoption of the standard may have on our consolidated financial statements and have not elected a transition method. Refer to Note 1 to our consolidated financial statements for additional information on the new guidance and its potential impact on us.

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, and 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 Arizona and Thailand. 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.

In addition to the facilities we own, we lease several manufacturing, research and development facilities and sales offices in North America, Europe and Asia.  Our aggregate monthly rental payment for our leased facilities is approximately $1.6 million.

We currently believe that our existing facilities are suitable and will be adequate to meet our requirements for at least the next 12 months.

Item 3. LEGAL PROCEEDINGSLegal Proceedings


In the ordinary course ofRefer to Note 11 to our business, we are involved in a limited number ofconsolidated financial statements for information regarding legal actions, both as plaintiff and defendant. Consequently, we could incur uninsured liability in any of those actions. We also periodically receive notifications from various third parties alleging infringement of patents or other intellectual property rights. With respect to pending legal actions to which we are a party, although the outcomes 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.  However, if an unfavorable ruling were to occur in any of the legal proceedings described below or in other legal proceedings that were not deemed material to us as of the date hereof, then such legal proceedings could 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, from time to time, subject to such litigation.  As a result, no assurances can be given with respect to the extent or outcome of any such litigation in the future.proceedings.
As a result of our acquisition of Atmel, which closed April 4, 2016, we became involved with the following lawsuits.
In re: Continental Airbag Products Liability Litigation. On May 11, 2016, an Amended and Consolidated Class Action Complaint ("Complaint") was filed in the United States District Court for the Southern District of Florida (Miami Division) against Atmel, Continental Automotive Systems, Inc., Honda Motor Co., Ltd. and an affiliate, and Daimler AG and an affiliate.

The Complaint which includes claims arising under federal law and Florida, California, New Jersey, Michigan and Louisiana state law-alleges that class members unknowingly purchased or leased vehicles containing defective airbag control units (allegedly incorporating defective application specific integrated circuits manufactured by Atmel between 2006 and 2010), and thereby suffered financial harm, including a loss in the value of their purchased or leased vehicles. The plaintiffs are seeking unspecified compensatory and exemplary damages, statutory penalties, pre- and post-judgment interest, attorneys' fees, and injunctive and other relief. Atmel intends to contest plaintiffs' claims vigorously.
Southern District of New York Action by LFoundry Rousset ("LFR") and LFR Employees. On March 4, 2014, LFR and Jean-Yves Guerrini, individually and on behalf of a putative class of LFR employees, filed an action in the United States District Court for the Southern District of New York (the "District Court") against Atmel, its French subsidiary, Atmel Rousset S.A.S. ("Atmel Rousset"), and LFoundry GmbH ("LF"), LFR's German parent. The case purports to relate to Atmel Rousset's June 2010 sale of its wafer manufacturing facility in Rousset, France to LF, and LFR's subsequent insolvency, and later liquidation, more than three years later. The District Court dismissed the case on August 21, 2015, and plaintiffs are appealing the dismissal.
Individual Labor Actions by former LFR Employees. In the wake of LFR's insolvency and liquidation, over 500 former employees of LFR have filed individual labor actions against Atmel Rousset in a French labor court. Atmel Rousset believes that each of these actions is entirely devoid of merit, and, further, that any assertion by any of the Claimants of a co-employment relationship with Atmel Rousset is based substantially on the same specious arguments that the Paris Commercial Court summarily rejected in 2014 in related proceedings. Atmel Rousset therefore intends to defend vigorously against each of these claims.

Discussions of the special charges for fiscal 2016, fiscal 2015 and fiscal 2014 are contained in Note 3 to our consolidated financial statements.

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 an entity which we 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. 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 expires in December 2018.

Item 7.MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


Note Regarding Forward-looking Statements

This report, including "Item 1 –1. Business," "Item 1A –1A. Risk Factors," and "Item 7 –7. Management's Discussion and Analysis of Financial Condition and Results of Operations," contains certain forward-looking statements that involve risks and uncertainties, including statements regarding our strategy, financial performance and revenue sources.  We use words such as "anticipate," "believe," "plan," "expect," "estimate," "future," "continue," "intend" and similar expressions to identify forward-looking statements.  Our actual results could differ materially from the results anticipated in these forward-looking statements as a result of certain factors including those set forth under "Risk Factors," beginning at page 12 and elsewhere in this Form 10-K.  Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance or achievements.  You should not place undue reliance on these forward-looking statements.  We disclaim any obligation to update information contained in any forward-looking statement.  These forward-looking statements include, without limitation, statements regarding the following:

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 8. Financial Statements and Supplementary Data." For an overview of our business and recent trends, refer to "Part I Item 1. Business."

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 36, weWe then discuss our Resultsresults of Operationsoperations for fiscal 20162022 compared to fiscal 2015, and for fiscal 2015 compared to fiscal 2014.  We then provide2021, followed by an analysis of changes in our balance sheet and cash flows, and discuss our financial commitments in the sectionssection titled "Liquidity and Capital Resources,Resources." "Contractual Obligations"Our liquidity and "Off-Balance Sheet Arrangements."

Strategy
Our goal iscapital resources section generally discusses fiscal 2022 compared to be a worldwide leader in providing specialized semiconductor products for a wide variety of embedded control applications.  Our strategic focus is on embedded control solutions, including general purpose and specialized microcontrollers, development tools and related software, analog, interface, mixed signal and timing products, wired and wireless connectivity products, memory products and technology licensing.  We provide highly cost-effective embedded control solutions that also offer the advantages of small size, high performance, extreme low power usage, wide voltage range operation, mixed signal integration and ease of development, thus enabling timely and cost-effective integrationfiscal 2021. For our discussion of our solutions byfiscal 2021 results compared to fiscal 2020 for both our customers in their end products.  We license our SuperFlash technology and other technologies to wafer foundries, integrated device manufacturers and design partners throughout the world for use in the manufactureresults of advanced microcontroller products, gate array, RF and analog products that require embedded non-volatile memory.

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 assemblyliquidity and test operations,capital resources sections, refer to "Item 7. Management’s Discussion and by employing statistical process control techniques, we have been able to achieveAnalysis of Financial Condition 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 portionResults 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, andOperations" 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 focusAnnual Report on Form 10-K for the design of new microcontrollers, digital signal controllers, memory, analog and mixed-signal products, Flash-IP systems, 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.fiscal year ended March 31, 2021 filed with the SEC on May 18, 2021, which is incorporated by reference herein.

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 client engagement manager (CEMs), embedded system engineer (ESEs), 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 ESE team is to provide technical assistance to strategic accounts and to conduct periodic training sessions for CEMs and distributor sales teams.  ESEs 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.

See "Our operating results are impacted by both seasonality and the wide fluctuation of supply and demand in the semiconductor industry," on page 15 for discussion of the impact of seasonality on our business.


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. GAAP.  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, senior and junior subordinated convertible debenturesConvertible Debt 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. 

Revenue Recognition

We also have other policies that we consider key accounting policies, such asgenerate revenue primarily from sales of our policy regardingsemiconductor products to distributors and non-distributor customers (direct customers) and, to a lesser extent, from royalties paid by licensees of our intellectual property. We apply the following five-step approach to determine the timing and amount of revenue recognitionrecognition: (i) identify the contract with the customer, (ii) identify performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to original equipment manufacturers (OEMs); however, wethe performance obligations in the contract, and (v) recognize revenue when the performance obligation is satisfied.

Sales to our distributors are governed by a distributor agreement, a purchase order, and an order acknowledgment. Sales to distributors 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 recognitionmeet the definition of a contract until the distributor sellshas sent in a purchase order, we have acknowledged the productorder, we have deemed the collectability of the consideration 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 abe probable, and legally enforceable right to payment, relieve inventory for the carrying value of goods shipped since legal title has passed to the distributor,rights 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 transactionobligations have been created. As is completedcustomary 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 negotiatedsemiconductor industry, we offer price concessions grantedand stock rotation rights 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, 2016, we had approximately $267.2 million of deferred revenue and $83.8 million in deferred cost of sales recognized as $183.4 million of deferred income on shipments to distributors.  At March 31, 2015, we had approximately $260.9 million of deferred revenue and $94.8 million in deferred cost of sales recognized as $166.1 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 $102.9 million at March 31, 2016 and $116.0 million at March 31, 2015.  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 capitalmany of our distributors. As such,these are forms of variable consideration, 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 onestimate the amount of ending inventory as reported byconsideration to which we will be entitled using recent historical data and applying the distributor multiplied by a negotiated percentage.  Such advances have no impact on ourexpected value method. After the transaction price has been determined and allocated to the performance obligations, we recognize revenue recognitionwhen the performance obligations are satisfied. Substantially all of the revenue generated from contracts with distributors is recognized at, or our consolidated statements of income.  We process

discounts taken by distributors against our deferred income on shipmentsnear to, distributors' balancethe time risk 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 pricetitle of the inventory ittransfers to the distributor.

Sales to our direct customers are generally governed by a purchase order and an order acknowledgment. Sales to direct customers usually do not meet the definition of a contract until the direct customer has on hand assent in a purchase order, we have acknowledged the order and deemed the collectability of the dateconsideration to be probable, and legally enforceable rights and obligations have been created. Generally, the transaction price associated with contracts with direct customers is set at the standalone selling price and is not variable. After the transaction price has been determined and allocated to the performance obligations, we recognize revenue when the performance obligations are satisfied. Substantially all of the price reduction.  There

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.expense.  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.  Under the acquisition method of accounting, the aggregate amount of consideration we pay for a company is allocated to net tangible assets and intangible assets based on their estimated fair values as of the acquisition date.  The excess of the purchase price over the value of the net tangible assets and intangible assets is recorded to goodwill. On an annual basis, we test goodwill for impairment and through March 31, 2016,2022, we have never recorded an impairment charge against our goodwill balance.related to goodwill. 
 
Share-based Compensation
 
We measure at fair valueutilize RSUs with a service condition as our primary equity incentive compensation instrument for employees and recognizealso grant market-based and performance-based PSUs to executive officers and employees. Share-based compensation expensecost 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 basedRSUs with a service condition or performance-based PSUs is measured on their respectivethe grant date fair values.  Total share-based compensation in fiscal 2016 was $71.4 million, of which $63.1 million was reflected in operating expenses.  Total share-based compensation included in cost of sales in fiscal 2016 was $8.3 million.  Total share-based compensation included in our inventory balance was $6.2 million at March 31, 2016.
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.dividends and is recognized as expense on a straight-line basis over the requisite service periods. 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, includingPSUs with a market condition using a Monte Carlo simulation model as of the Black-Scholes model, require the usedate 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 thangrant 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 2016 was immaterial.

We evaluate the assumptions used to value our awards on a quarterly basis.  If factors change and we employ different assumptions,Total share-based compensation expense may differ significantly from what we have recordedrecognized during the fiscal 2022 was $210.2 million, of which $175.9 million was reflected in the past.  operating expenses and $34.3 million was reflected in cost of sales. Total share-based compensation included in our inventory was $7.5 million at March 31, 2022.

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 marketnet realizable value 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 marketnet realizable 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 inventoryreserves for obsolescence, we primarily evaluate estimates ofprojected demand over a 12-month periodperiods that align with demand forecasts used to develop manufacturing plans and record impairment chargesinventory build decisions and provide 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 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 resultDuring fiscal 2022, we operated at above normal
37

capacity levels. During fiscal 2021, we operated at below normal operatingcapacity levels primarily due to general economic conditions and uncertainty from the COVID-19 pandemic resulting in our wafer fabrication facilities, approximately $1.9 million, $0.8 million and $19.0 million was charged directly to costunabsorbed capacity charges of sales in fiscal 2016, fiscal 2015 and fiscal 2014, respectively.$29.6 million.
 
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, 2016, the valuation allowances totaled $161.8 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, 2016, our deferred tax asset, net of valuation allowances, was $122.2million.

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.  We are currently under IRS audit for fiscal years 2011 and 2012. We recognize liabilities for anticipatedbeing audited by the tax audit issuesauthorities in the U.S. and otherin various foreign jurisdictions. At this time, we do not know what the outcome of these audits will be. We record benefits for uncertain tax jurisdictionspositions based on our estimatean assessment of whether andit is more likely than not that the extent to which, additional tax payments are probable.  We believepositions will be sustained based on their technical merits under currently enacted law. If this threshold is not met, no tax benefit of the uncertain tax position is recognized. If the threshold is met, we recognize the largest amount of the tax benefit 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 proveis more than 50% likely to be unnecessary,realized upon ultimate settlement.  

The accounting model related to the resulting reversalvaluation of such reserves would resultuncertain tax positions requires us to presume that the tax position will be examined by the relevant taxing authority that has full knowledge of all relevant information and that each tax position will be evaluated without consideration of the possibility of offset or aggregation with other positions.  The recognition requirement for the liability exists even if we believe the possibility of examination by a taxing authority or discovery of the related risk matters is remote or where we have a long history of the taxing authority not performing an exam or overlooking an issue.  We will record an adjustment to a previously recorded position if new information or facts related to the position are identified in tax benefits beinga subsequent period.  All adjustments to the positions are recorded inthrough 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 wouldincome statement.  Generally, adjustments will be recorded in periods subsequent to the initial recognition if the taxing authority has completed an audit of the period that results in which the assessment is determined. position being effectively settled or if the statute of limitation expires.  Due to the inherent uncertainty in the estimation process and in consideration of the criteria of the accounting model, amounts recognized in the financial statements in periods subsequent to the initial recognition may significantly differ from the estimated exposure of the position under the accounting model.
 


Senior and Junior Subordinated Convertible DebenturesDebt
 
WeUpon issuance, we separately account for the liability and equity components of our seniorConvertible Debt by estimating the fair values of the i) liability component without a conversion feature and junior subordinated convertible debentures in a manner that reflects our nonconvertible debt (unsecured debt) borrowing rate when interest cost is recognized.ii) the conversion feature. 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.

Upon settlement of our Convertible Debt instruments, we allocate the total consideration between the liability and equity components based on the fair value of the liability component without the conversion feature. The difference between the consideration allocated to the liability component and the net carrying value of the liability component is recognized as an extinguishment loss or gain. The remaining settlement consideration is allocated to the equity component and recognized as a reduction of additional paid-in capital in our consolidated balance sheets. In addition, if the terms of the settlement are different from the contractual terms of the original instrument, we recognize an inducement loss, which is measured as the difference between the fair value of the original terms of the instrument and the fair value of the settlement terms.

Determining the fair value of the liability component without the conversion feature upon issuance and settlement involves estimating the equivalent borrowing rate for a similar non-convertible instrument. Given the values of these transactions, fair value estimates are sensitive to changes in the equivalent borrowing rate conclusions. The measurement of the equivalent borrowing rate requires that we make estimates of volatility and credit spreads to align observable market inputs with the instrument being valued.

Lastly, we include the dilutive effect of the shares of our common stock issuable upon conversion of the outstanding senior and junior subordinated convertible debenturesConvertible Debt in our diluted income per share calculation regardless of whether the market price triggers or other contingent conversion features have 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 senior and junior subordinated convertible debenturesConvertible Debt 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 prices per share which were $66.05 and $24.31 for the senior and junior subordinated convertible debentures, respectively, at March 31, 2016 and adjusts as dividends are recorded in the future.

In the ordinary course of our business, we are exposed to various liabilities as a result of contracts, product liability, customer claims, governmental investigations and other matters.  Additionally, we are involved in a limited number of legal actions, both as plaintiff and defendant, anddefendant.  Consequently, we could incur uninsured liability in any one or more of them.those actions.  We also periodically receive notifications from various third parties alleging infringement of patents or other intellectual property rights, or other matters.from customers requesting reimbursement for various costs.  With respect to pending legal actions to which we are a party and other claims, although the outcomes of these actions are generally 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, governmental investigations and disputes relating to the semiconductor industry isare not uncommon, and we are, and from time to time, have been, subject to such litigation.  Nolitigation, governmental investigations and disputes.  As a result, no assurances can be given with respect to the extent or outcome of any such litigation, governmental investigations or disputes in the future.


We accrue for claims and contingencies when losses become probable and reasonably estimable. As of the end of each applicable reporting period, we review each of our matters and, where it is probable that a liability has been or will be incurred, we accrue for all probable and reasonably estimable losses. Where we can reasonably estimate a range of losses we may incur regarding such a matter, we record an accrual for the amount within the range that constitutes our best estimate. If we can reasonably estimate a range but no amount within the range appears to be a better estimate than any other, we use the amount that is the low end of such range. Contingencies of an acquired company that exist as of the date of the acquisition are measured at fair value if determinable, which generally is based on a probability weighted model. If fair value is not determinable, contingencies of an acquired company are recognized when they become probable and reasonably estimable.

Net sales$6,820.9 $5,438.4 25.4 %

The increase in net sales in fiscal 2016 over2022 compared to fiscal 20152021 was primarily due primarilyto strong business conditions that began in the second half of fiscal 2021 as businesses and individuals adapted to the effects of the COVID-19 pandemic. Business conditions continued to be exceptionally strong in fiscal 2022. Additionally, semiconductor industry conditions have resulted in increased costs throughout our supply chain, which we have been passing on to our acquisitioncustomers in the form of Micrel, offset in part by weaker general economic and semiconductor industry conditions. Theprice increases. These price increases also contributed to the increase in net sales during fiscal 2022 compared to fiscal 2021. Our price increases were implemented at various times and in various amounts throughout fiscal 2022 with respect to our very broad range of customers and products. Due to the complexity of the implementation of the price increases and the changes in product, geographic and customer mix, we are not able to quantify the impact of the price increases on our net sales.

The net sales value of inventory at our distributor customers increased $11.2 million during fiscal 2022 compared to a decrease of $10.4 million during fiscal 2021. Excluding the impact of changes in distributor inventory levels on net sales, net sales increased by 25.0% in fiscal 2015 over2022 compared to fiscal 20142021. Our price increases positively impacted net sales during fiscal 2022. Additionally, demand for our products was due primarilypositively impacted by strength in our microcontroller and analog product lines. Due to the size, complexity and diversity of our acquisitions of ISSC and Supertex, market share gains and improved general economic and semiconductor industry conditionscustomer base, we are not able to quantify any material factor contributing to the change other than net demand fluctuations in the end markets that we serve. Average selling prices for

Other factors that we believe contributed to changes in our semiconductor products were down approximately 3% in fiscal 2016 over fiscal 2015 and were up approximately 2% in fiscal 2015 over fiscal 2014. The number of units of our semiconductor products sold was up approximately 6% in fiscal 2016 over fiscal 2015 and up approximately 11% in fiscal 2015 over fiscal 2014. 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 ofreported net sales during the last threefor fiscal years2022 compared to fiscal 2021 and which are drivers of long-term trends in our net sales but which factors we are not able to quantify include:

our acquisition of Micrel, which closed on August 3, 2015;
global economic conditions in the markets we serve;
semiconductor industry conditions;
our acquisition of ISSC on July 17, 2014;
our acquisition of Supertex on April 1, 2014;

Microcontrollers
 
Our microcontroller product line represents the largest component of our total net sales.  Microcontrollers and associated application development systems accounted for approximately 61.9%56.0% and 54.5% of our net sales in fiscal 2016, approximately 64.9% of our net sales in2022 and fiscal 2015 and approximately 65.3% of our net sales in fiscal 2014.2021, respectively.
 
Net sales of our microcontroller products decreasedincreased approximately 3.5%28.8% in fiscal 20162022 compared to fiscal 2015, and increased approximately 10.5% in fiscal 2015 compared to fiscal 2014.  The decrease in net sales in fiscal 2016 compared to fiscal 2015 resulted primarily from weaker general economic and semiconductor industry conditions in the end markets we serve including the consumer, automotive, industrial control, communications and computing markets.2021. The increase in net sales was due primarily to strength in fiscal 2015 compared to fiscal 2014 resulted primarily fromdemand for our acquisition of ISSCmicrocontroller products in the second quarter of fiscal 2015, market share gains and improved general economic and semiconductor industry conditions in the end markets that we serve.serve and our price increases.


Historically, average selling prices in the semiconductor industry decrease over the life of any particular product. TheHowever, the overall average selling prices of our microcontroller products have increased in recent periods and have remained relatively constantstable 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

Analog
 
Analog, Interface, Mixed Signal and Timing Products
Sales of ourOur analog product line includes analog, interface, mixed signal and timing productsproducts. Our analog product line accounted for approximately 27.4%28.4% and 27.9% of our net sales in fiscal 2016, approximately 23.3% of our net sales in2022 and fiscal 2015 and approximately 22.2% of our net sales in fiscal 2014.2021, respectively.

Net sales offrom our analog interface, mixed signal and timing productsproduct line increased approximately 18.8%27.6% in fiscal 20162022 compared to fiscal 2015 and increased approximately 17.0% in fiscal 2015 compared to fiscal 2014.2021. The increase in net sales was primarily due to strength in fiscal 2016 compared to fiscal 2015 was driven primarily bydemand for our acquisition of Micrelanalog products in the second quarter of fiscal 2016end markets that we serve and market share gains achieved within the analog, interface, mixed signal and timing market. The increase in net sales in fiscal 2015 compared to fiscal 2014 was driven primarily by our acquisition of Supertex in the first quarter of fiscal 2015, improved general economic and semiconductor industry conditions and market share gains achieved within the analog, interface, mixed signal and timing market.

price increases.
 
Analog, interface, mixed signal and timing products can be proprietary or non-proprietary in nature.  Currently, weWe consider more than a majority of the products in our analog interface, mixed signal and timing product mixline 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, mixed signal and timing businessproduct line 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, mixed signal and timing 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, mixed signal and timing products will increase over time. 


Memory ProductsOther
 
Sales of our memoryOur other product line includes FPGA products, accounted for approximately 5.4% of our net sales in fiscal 2016, approximately 6.2% of our net sales in fiscal 2015 and approximately 7.0% of our net sales in fiscal 2014.
Net sales of our memory products decreased approximately 11.6% in fiscal 2016 compared to fiscal 2015, and decreased approximately 1.8% in fiscal 2015 compared to fiscal 2014.  The decreases in memory product net sales in fiscal 2016 compared to fiscal 2015 and in fiscal 2015 compared to fiscal 2014 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.

Technology Licensing
Technology licensing revenue includes a combination of royalties associated with licenses for the use of our SuperFlash and other technologies, andsales of our intellectual property, fees for engineering services. Technology licensingservices, memory products, timing systems, manufacturing services (wafer foundry and assembly and test subcontracting), legacy application specific integrated circuits, and certain products for aerospace applications. Revenue from these services and products accounted for approximately 4.1%15.6% and 17.6% of our net sales in fiscal 2016, approximately 4.2% of our net sales in2022 and fiscal 2015 and approximately 4.9% of our net sales in fiscal 2014.2021, respectively.


Net sales related to our technology licensing decreasedthese products and services increased approximately 0.5%11.4% in fiscal 20162022 compared to fiscal 20152021. The increase in net sales was primarily due to strength in demand for our products in end markets that we serve and decreased approximately 5.3% in fiscal 2015 compared to fiscal 2014. Revenue from technology licensingour price increases. Net sales of our other product line can fluctuate over time based on the production activities of our licensees as well as general economic and semiconductor industry conditions.

Distribution
 
Distributors accounted for approximately 53%48% and 50% of our net sales in fiscal 2016, approximately 51%2022 and fiscal 2021, respectively. The decrease in the distribution percentage of our total net sales in fiscal 2015 and approximately 53%is due to lower Preferred Supply Program participation among our distributors as priority of our net sales in fiscal 2014.
Our two largest distributors together accounted for approximately 12% of our net sales in each of fiscal 2016 and 2015, and approximately 14% of our net sales in fiscal 2014.supply under the Preferred Supply Program is more prevalent with direct customers. No single distributor or end customer accounted for more than 10% of our net sales in fiscal 2016, 20152022 or 2014.fiscal 2021. 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 Microchip for its products and brand name and use distributors as an effective supply channel.

Generally, we do not have long-term agreements with our distributors and we, or our distributors, may terminate our relationshiprelationships with each other with little or no advanced notice.advance notice, with the exception of orders placed under our Preferred Supply Program.  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, 2016,2022, our distributors maintained 3217 days of inventory of our products compared to 3722 days at March 31, 2015 and 33 days at March 31, 2014.2021. Over the past fiveten fiscal years, the days of inventory maintained by our distributors have fluctuated between approximately 2717 days and 4740 days. We do not believe that inventoryInventory holding patterns at our distributors will materiallymay have a material impact on our net sales,sales. Our distributor inventory days are at historic lows due to the fact that we recognize revenue based on sell-throughimbalance between the supply of and the demand for all of our distributors.products in the current supply-constrained environment.

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%78% and 77% of our net sales in each of fiscal 2016, 20152022 and 2014.fiscal 2021, respectively. Substantially all of our foreign sales are U.S. dollar denominated. Sales to customers in Asia have generallyEurope as a percentage of total net sales increased over timein fiscal 2022 compared to fiscal 2021 primarily due to many of our customers transitioning their manufacturing operations to Asia and growthstrength in demand from the emerging Asian market.in our microcontroller and analog product lines. 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 30%, 28% and 29% of our net sales in fiscal 2016, 2015 and 2014, respectively.  Sales to customers in Taiwan accounted for approximately 12%, 14% and 13% of our net sales in fiscal 2016, 2015 and 2014, respectively.  We did not have sales into any other countries that exceeded 10% of our net sales during the last three fiscal years.

The most significant factors affecting our gross profit percentage in the periods covered by this report were:
Unabsorbed capacity charges of approximately $44.9 million in fiscal 2016 and approximately $24.4 million in fiscal 2015 related to the recognition of acquired inventory at fair value as a result of our acquisitions- When production levels are below normal capacity, which increased the value of our acquired inventory and subsequently increased our cost of sales and reduced our gross margins;
for each of fiscal 2016 and fiscal 2015, 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, interface, mixed signal and timing 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 depreciationwe measure as a percentage of the capacity of the installed equipment, we charge cost of sales.

sales for the unabsorbed capacity. We consider normal capacity at Fab 2 and Fab 4 to be 90% to 95%. We consider normal capacity at Fab 5 to be 70% to 75%. During fiscal 2022, we operated at above normal capacity levels and we expect this to continue if the current supply constraints relative to demand continue. During fiscal 2021, we operated at below normal capacity levels primarily due to general economic conditions and uncertainty from the COVID-19 pandemic resulting in unabsorbed capacity charges of $29.6 million. 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

Net impact of product mix and average gross profit per unit - The net impact of product mix and average gross profit per unit may fluctuate over time due to sales volumes of lower or higher margin products, changes in selling prices, and fluctuations in product costs. During fiscal 2022, product mix resulted in a decrease of $152.5 million in cost of sales for the unabsorbed capacity. Our wafer fabrication facilities operated below normal capacity levels, which we typically considergoods sold and an increase in gross profit compared to be 90% to 95% of the actual capacity of the installed equipment, during the third quarter of fiscal 2016, the first quarter of fiscal 2015 and all of fiscal 2014 in response to uncertain global economic conditions and our inventory position. As a result of production being below normal operating levels in our wafer fabs, approximately $1.9 million, $0.8 million and $19.0 million was charged to cost of sales in fiscal 2016, fiscal 2015 and fiscal 2014, respectively. Our wafer fabrication facilities operated at normal capacity levels during the fourth quarter of fiscal 2016. In the future, if production levels are below normal capacity, we will charge cost of sales for the unabsorbed capacity.  We operated at slightly below normal capacity levels in our Thailand assembly and test facilities during the third quarter of fiscal 2016. As a result, we charged cost of sales approximately2021.

$1.0 million during fiscal 2016. During fiscal 2015 and fiscal 2014, we operated at normal levels of capacity at our Thailand assembly and test facilities, and we selectively increased our assembly and test capacity at such facilities during such time.
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.  Substantially all of our production has been on 8-inch wafers during the periods covered by this report.


Our overall inventory levels were $306.8$854.4 million at March 31, 2016,2022, compared to $279.5$665.0 million at March 31, 2015 and $262.7 million at March 31, 2014.2021. We maintained 110125 days of inventory on our balance sheet at March 31, 20162022 compared to 111112 days of inventory at March 31, 2015 and 118 days at March 31, 2014.2021. We expect our days of inventory levels in theat June 2016 quarter30, 2022 to increase from 1be 128 to 9 days from the March 2016 levels, not including the impact from inventory acquired from our Atmel acquisition. We believe our existing level of inventory will allow us to maintain competitive lead times and provide strong delivery performance to our customers.134 days.
 
We anticipate that our gross margins will fluctuate over time, driven primarily by capacity utilization levels, the overall product mix of microcontroller, analog, interface, mixed signal and timingFPGA 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. We continue to transition products to more advanced process technologies to reduce future manufacturing costs.

We operate assembly and test facilities in Thailand, the Philippines, and other locations throughout the world. During fiscal 2016,2022, approximately 53%59% of our assembly requirements were performed in our Thailandinternal assembly facilities, compared to approximately 53% during fiscal 2021. During fiscal 2022, approximately 64% of our test requirements were performed in our internal test facilities, compared to approximately 57% during fiscal 20152021. The increases in the percentage of assembly and approximately 51% duringtest operations that were performed internally in fiscal 2014.2022 compared to fiscal 2021 are primarily due to our investments in assembly and test equipment, which increased our internal capacity capabilities. Third-party contractors located primarily in Asia perform the balance of our assembly and test operations. The percentage of our assembly workand test operations that isare 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 2016, approximately 81% of our test requirements were performed in our Thailand facilities compared to approximately 88% during fiscal 2015 and approximately 86% during fiscal 2014. The primary reason for the percentage reduction in the assembly and test operations performed in our Thailand facilities in fiscal 2016 compared to the prior periods is our acquisition of Micrel, which outsourced these activities. Over time, we intend to migrate a portion of the outsourced assembly and test activities to our Thailand facilities. We believe that the assembly and test operations performed at our Thailandinternal 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 plan to continue to transition certain outsourced assembly and test capacity to our internal facilities.

We rely on outside wafer foundries for a significant portion of our wafer fabrication requirements. During eachApproximately 60% of fiscal 2016 and 2015, approximately 39% of our total net sales came from products that were produced at outside wafer foundries in fiscal 2022, compared to approximately 38% during61% in fiscal 2014.2021.


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)

Other Income (Expense)

Interest income in fiscal 20162022 was $24.4$0.5 million compared to $19.5$1.7 million in fiscal 2015 and $16.5 million in fiscal 2014.  The primary reasons for the increases in interest income over these periods relates to higher yields on short-term cash investments and higher invested cash balances.2021.


Interest expense in fiscal 20162022 was $104.0$257.0 million compared to $62.0$356.9 million in fiscal 2015 and $48.7 million in fiscal 2014.2021. The primary reasonsreason for the increasedecrease in interest expense in fiscal 20162022 compared to fiscal 20152021 relates to non-cash interest expense from the amortization on the debt discountcumulative pay down of our 1.625% senior subordinated convertible debenturesdebt and lower interest expenserates on our outstanding variable rate debt.

Loss on settlement of debt in fiscal 2022 was $113.4 million compared to $299.6 million in fiscal 2021. In fiscal 2022, the losses primarily related to the 1.625% coupon on such debentures which were issued in February 2015. The increase in interest expense was partially offset by lower interest expense on our 2.125% junior subordinated convertible debentures assettlement of a resultportion of our purchase of 50% of such outstanding debentures in2015 Senior Convertible Debt, our 2017 Senior Convertible Debt, and our 2017 Junior Convertible Debt as well as the fourth quarter of fiscal 2015.

In fiscal 2021, the losses primarily related to the settlement of a portion of our outstanding 2015 Senior Convertible Debt, our 2017 Senior Convertible Debt, and our 2017 Junior Convertible Debt as well as the payment of all amounts outstanding under our Bridge Loan Facility, and our Term Loan Facility. The net losses recognized on market value.

Provision for Income Taxes

Our provision or benefit for income taxes reflectsis attributable to U.S. federal, state, and foreign income taxes. A comparison of our tax on our foreign earnings and federal and state tax on U.S. earnings.  We had an effective tax rate benefit of 15.2%rates in fiscal 20162022 and 5.6% in fiscal 2015 and an effective tax rate of 8.6% in fiscal 2014.  Excluding certain tax events described below, our effective tax rates were lower than statutory rates in the U.S. primarily2021 is not meaningful due to our mixthe amount of earnings in foreign jurisdictions with lowerpre-tax income, and income tax rates andbenefit recorded during the R&D tax credit.  prior period.

Our effective tax rate in fiscal 2016 includes $12.1 million of benefits related to audit closures and expirations of the statute of limitations on various tax reserves and $15.5 million of benefits related to intercompany prepaid tax amortization, which reduced our effective rate by 4.3% and 5.5%, respectively. Our effective tax rate in fiscal 2016 also2022 includes a $2.5$49.5 million benefit received from the reinstatement of the R&D credit and a $13.5 milliontax benefit received from current year generated R&D credits, which reduced our effective tax rate by 0.9% and 4.8%, respectively. Our3.3%; a $17.6 million tax benefit for share-based compensation deductions, which reduced our effective tax rate in fiscal 2015 included $33.1by 1.2%; a $47.1 million of benefitstax benefit related to audit closures and expirations of the statute of limitations onchanges in various tax reserves, which reduced our effective tax rate by 9.6%.

During fiscal 2014, our

Our effective tax rate included $19.4in fiscal 2021 includes a $47.6 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 benefitsbenefit received from generated R&D credits, which reduced our effective tax rate by 4.5% to an14.0%; a $12.3 million tax benefit for share-based compensation deductions, which reduced our effective tax rate by 3.6%; a $28.1 million tax expense related to changes in various tax reserves, which increased our effective tax rate by 8.3%; a $122.5 million tax expense for the effects of 8.6%foreign operations, which increased our effective tax rate by 36.1%; a $48.1 million tax benefit related to the settlement of convertible debt, which reduced our effective tax rate by 14.2%; and a $63.8 million tax benefit related to intra-group transfers of certain intellectual property rights, which reduced our effective tax rate by 18.8%. The tax benefit for the intra-group asset transfers primarily consisted of $155.5 million recorded as a deferred tax asset which represents the book and tax basis difference on the transferred assets measured based on the new applicable statutory tax rate, as well as the reversal of the pre-existing deferred tax asset of $90.3 million, which represents the book and tax basis difference on the transferred assets measured based on the applicable statutory tax rate prior to the transfer. Over the next 15 years, we expect to be able to realize the future tax benefit of the deferred tax assets resulting from the intra-group asset transfers. It is not uncommon for taxing authorities of different countries to have conflicting views, for instance, with respect to, among other things, the manner in which the arm’s length standard is applied
44

with respect to the valuation of intellectual property rights. The taxing authorities of jurisdictions in which we operate may challenge our methodologies for valuing the intellectual property rights transferred, which could increase our future effective income tax rate and harm our future results of operations.

We are subject to taxation in many jurisdictions in which we have operations. The effective tax rates that we pay in these jurisdictions vary widely, but they are generally lower than our combined U.S. federal and state effective tax rate. Our domestic blended statutory tax rate in each of fiscal 2022 and fiscal 2021 was approximately 22%. Our non-U.S. blended statutory tax rates in fiscal 2022 and fiscal 2021 were lower than this amount. The difference in rates applicable in foreign jurisdictions results from a number of factors, including lower statutory rates, tax holidays, financing arrangements and other factors. Our effective tax rate has been and will continue to be impacted by the geographical dispersion of our earnings and losses.

Our foreign tax rate differential benefit primarily relates to our operations and assets in Thailand and Ireland. Our Thailand manufacturing operations are currently subject to numerous tax holidays granted to us based on our investment in property, plant, and equipment in Thailand. Our tax holiday periods in Thailand expire at various times in the future; however, we actively seek to obtain new tax holidays, otherwise we will be subject to tax at the statutory tax rate of 20%. We do not expect the future expiration of any of our tax holiday periods in Thailand to have a material impact on our effective tax rate.  The remaining material components of foreign income taxed at a rate lower than the U.S. are earnings accrued in Ireland at a 12.5% statutory tax rate.

In September 2021, we received a Statutory Notice of Deficiency (Notice) from the Internal Revenue Service (IRS) for fiscal 2007 through fiscal 2012. The disputed amounts largely relate to transfer pricing matters. We firmly believe that the assessments are without merit and plan to pursue all available administrative and judicial remedies necessary to resolve this matter. In December 2021, we filed a petition in the United States Tax Court challenging the Notice. We intend to vigorously defend our position and we are confident in our ability to prevail on the merits. We regularly assess the likelihood of adverse outcomes resulting from examinations such as this to determine the adequacy of our tax reserves. We believe that the final adjudication of this matter will not have a material impact on our consolidated financial position, results of operations or cash flows and that we have adequate tax reserves for all tax matters. However, the ultimate outcome of disputes of this nature is uncertain, and if the IRS were to prevail on all of its assertions, the assessed tax, penalties, and deficiency interest could have a material adverse impact on our financial position, results of operations or cash flows.

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 20112007 and later tax returns remain effectively open for examination by the taxing authorities. We recognize liabilities for anticipatedare currently being audited by the tax audit issuesauthorities in the U.S. and otherin various foreign jurisdictions. At this time, we do not know what the outcome of these audits will be. We record benefits for uncertain tax jurisdictionspositions based on our estimatean assessment of whether andit is more likely than not that the extent to which, additional tax payments are probable.  We believepositions will be sustained based on their technical merits under currently enacted law. If this threshold is not met, no tax benefit of the uncertain tax position is recognized. If the threshold is met, we recognize the largest amount of the tax benefit 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 proveis more than 50% likely to be unnecessary, the resulting reversalrealized upon ultimate settlement.

Table 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.Contents
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 $2,564.6$319.4 million in cash, cash equivalents and short-term and long-term investments at March 31, 2016,2022, an increase of $222.4$37.4 million from the March 31, 20152021 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 and increases in borrowings under our credit facility offset in part by our dividend payments of $291.1 million and $343.9 million of cash, net of cash acquired, used for our acquisition of Micrel.
 
Operating Activities

Net cash provided fromby operating activities was $744.5 million$2.84 billion for fiscal 2016, $721.2 million for fiscal 2015 and $676.6 million for fiscal 2014.  The increase in cash flow from operations in fiscal 2016 compared to fiscal 2015 was2022, primarily due to higher net salesincome of $1.29 billion, adjusted for non-cash and an increase innon-operating charges of $1.52 billion and net cash inflows of $34.2 million from changes in our operating assets and liabilities. The primary drivers of the changes in operating assets and liabilities in fiscal 2022 include an increase in cash flow from operations in fiscal 2015 compared to fiscal 2014 wastrade accounts receivable driven primarily due toby higher net sales during fiscal 2015.
and an increase in inventories related to increased production levels and higher costs of materials and production costs in support of customer demand for our products, offset by increases in accounts payable, accrued and other liabilities driven by timing of payments to our suppliers, higher accrued employee compensation and sales related reserves. Net cash provided by investingoperating activities was $800.4 million$1.92 billion for fiscal 2016. 2021, primarily due to net income of $349.4 million, adjusted for non-cash and non-operating charges of $1.59 billion and net cash outflows of $27.0 million from changes in our operating assets and liabilities. The primary drivers of the changes in operating assets and liabilities in fiscal 2021 include an increase in trade accounts receivable and lower inventories related to improved business conditions in the second half of fiscal 2021 as businesses recovered from the effects of the COVID-19 pandemic.

Investing Activities

Net cash used in investing activities was $678.3$477.7 million for fiscal 2015 and $503.3 million in fiscal 2014.  The primary reason for the increase in cash from investing activities in fiscal 20162022 compared to $173.3 million for fiscal 2015 was an increase in2021. Fiscal 2022 and fiscal 2021 investing cash from our salesflows primarily related to capital purchases and maturities of available-for-sale investments of $1,112.6 million, offset in part by $343.9 million of cash consideration, net of $99.2 million of cash and cash equivalents acquired, used to finance our acquisition of Micrel in August 2015. The increase in net cash used in investing

activities in fiscal 2015 compared to fiscal 2014 was due primarily to $252.5 million of cash consideration, net of $15.1 million of cash and cash equivalents acquired, used to finance our acquisition of ISSC in July 2014 and $375.4 million of cash consideration, net of $14.8 million of cash and cash equivalents acquired, used to finance our acquisition of Supertex in April 2014, offset in part by an increase in cash from our purchases, sales and maturities of available-for-sale investments in fiscal 2015 compared to the prior year.other assets.

Our level of capital expenditures varies from time to time as a result of actual and anticipated business conditions. Capital expenditures were $97.9$370.1 million and $92.6 million in fiscal 2016, $149.5 million in2022 and fiscal 2015 and $113.1 million in fiscal 2014.2021, respectively. Capital expenditures arewere primarily for the expansion of production capacity and the addition of research and development equipment. Towards the second half of fiscal 2021 we started to invest more significantly to expand manufacturing capacity in response to supply constraints relative to current demand levels and we expect this to continue through calendar 2022 and into calendar 2023. We currently intend to spend approximately $140invest between $450 million and $550 million in equipment and facilities 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.months. We believe that the capital expenditures anticipated to be incurred over the next twelve months will provide sufficient manufacturing capacity to meetsupport the growth of our production capabilities for our new products and technologies and to bring in-house more of the assembly and test operations that are currently anticipated needs.outsourced. We expect to finance our capital expenditures through our existing cash balances and cash flows from operations.

Financing Activities

Net cash used in financing activities was $59.9 million$2.33 billion for fiscal 20162022 compared to net cash provided by financing activities of $98.5million for fiscal 2015 and net cash used in financing activities of $235.0 million$1.86 billion for fiscal 2014.  We made payments on2021. Significant transactions affecting our borrowings undernet financing cash flows include:
in fiscal 2022, $1.38 billion of cash used to pay down certain principal of our credit agreementsdebt, including the cash portion of $1,614.5 million during fiscal 2016, $2,047.6 million during fiscalthe settlement of our 2015 Senior Convertible Debt, our 2017 Senior Convertible Debt, and $1,103.5 million during fiscal 2014.

In February 2015, we issued $1,725.0 million principal amountour 3.922% 2021 Notes, partially funded by the issuance of 1.625% senior subordinated convertible debentures due February 15, 2025. The debentures are subordinated to our senior notes, and
in fiscal 2021, $1.41 billion of cash used to pay down certain principal of our debt, including amounts borrowed under our amended credit facility, but are senior to our outstanding 2.125% junior subordinated convertible debentures. Also, in February 2015, we acquired certainRevolving Credit Facility, Term Loan Facility and Bridge Loan Facility, and the cash portion of the settlement of our 2.125% junior subordinated convertible debentures with a $575.0 million aggregate principal amount for an aggregate purchase price of $1,134.6 million, based on market value.

in fiscal 2016, $286.5 million in fiscal 2015, and $281.2 million in fiscal 2014. Proceeds from the exercise of stock options and employee purchases under our employee stock purchase plans were $28.7 million for fiscal 2016, $34.4 million for fiscal 2015 and $60.1 million for fiscal 2014.

In February 2015,2022, we amended our $2.0 billion credit agreement with certain lenders.  As a result of such amendment, the revolving credit facility portion of the agreement was increased from $1,650.0 million to $2,555.0 million and the $350.0 million term loan portion of the agreement was removed. The increase option permitting us, subject to certain requirements, to arrange with existing lenders or new lenders to provide up to an aggregate of $300.0 million in additional commitments, was also adjusted to $249.4 million. In December 2015, we exercised our increase option in our credit agreement to obtain additional revolving commitments of $219.0 million, bringing our total revolving credit facility commitments to $2,774.0 million. Proceeds of loans made under the credit agreement may be used for working capital and general corporate purposes. At March 31, 2016, $1,052.0 million of borrowings were outstanding under the credit agreement. See Note 16 of the notes to consolidated financial statements for more information regarding our credit agreement.

Our total cash, cash equivalents, short-term investments and long-term investments held by our foreign subsidiaries was $2,559.3 million at March 31, 2016 and $2,322.4 million at March 31, 2015. 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, 2016 and March 31, 2015 was approximately $5.3 million and $19.8 million, respectively. We utilize a variety of tax planning and financing strategies (including borrowings under our credit agreement) 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.

In March 2015, we entered into ten-year fixed-to-floating interest rate swap agreements on a portion of our fixed-rate 1.625% senior subordinated convertible debentures. The interest rate swap agreements are designated as fair value hedges. We paid variable interest equal to the three-month LIBOR minus 53.6 basis points and we received a fixed interest rate of 1.625%. The gross notional amount of these contracts outstanding at March 31, 2015 was $431.3 million. In February 2016, the Company terminated its interest rate swap agreements. Upon termination, the contracts were in an asset position, resulting in cash receipts of approximately $25.7 million, which included $3.7 million of accrued interest. The cash flows from the

termination of these interest rate swap agreements have been reported as operating activities in the consolidated statement of cash flows.

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, 2016, we had no foreign currency forward contracts outstanding.

On August 3, 2015, we acquired Micrel for $14.00 per share and paid an aggregate of approximately $430.0 million in cash and issued an aggregate of 8.6millionrepurchased shares of our common stock for $425.6 million.

In December 2021, we amended and restated our Credit Agreement in its entirety. The amended and restated Credit Agreement provides for an unsecured revolving loan facility up to Micrel shareholders. We financed$2.75 billion that terminates on December 16, 2026. The Credit Agreement also permits us, subject to certain conditions, to add one or more incremental term loan facilities or increase the cash portionrevolving loan commitments up to $750.0 million. As of March 31, 2022, the purchase price withprincipal amount of our outstanding indebtedness was $7.84 billion. At March 31, 2022, we had $1.40 billion of outstanding borrowings under the Revolving Credit Facility compared to $2.35 billion at March 31, 2021. During fiscal 2021, we used borrowings under our existing credit agreement.Revolving

On April 4, 2016, we completed our acquisition Atmel. Under the terms of the merger agreement executed on January 19, 2016, Atmel stockholders received $8.15 per share in a combination of $7.00 per share in cashCredit Facility and $1.15 per share in shares of Microchip common stock. We financed the purchase price of our Atmel acquisition using approximately $2.04 billion of cash, cash equivalents, short-term investments and long-term investments held by certain of our foreign subsidiaries, approximately $0.94 billionproceeds from additional borrowings under our existing line of credit agreement and approximately $489 million through the issuance of an aggregate of 10.1 million shares of our common stock. The acquisition price represents a total equity value of approximately $3.47 billion, and a total enterprise value of approximately $3.43 billion, after excluding Atmel's cash and investments net of debt of approximately $39.3 million. The acquisition was structured in a manner that enabled us0.972% 2024 Notes to utilize a substantial portion of the cash, cash equivalents, short-term investments and long-term investments held by certain ofrepay all amounts outstanding under our foreign subsidiaries in a tax efficient manner. Although we believe our determinations with respect to the tax consequences of the acquisition are reasonable, we are regularly audited by the IRS and may be audited by other taxing authorities, and there can be no assurance as to the outcome of any such audit.Term Loan Facility.


Capital Returns

In May 2015,November 2021, our Board of Directors authorized the repurchase of up to 20.0 million shares$4.00 billion of our common stock in the open market or in privately negotiated transactions. In fiscal 2022, we repurchased approximately 5.6 million shares of our common stock for $425.6 million under this authorization. We did not repurchase any shares of our common stock in fiscal 2021. As of March 31, 2016, we had repurchased 8.6 million shares under this authorization for approximately $363.8 million.  In January 2016, our Board of Directors authorized an increase in the existing share repurchase program to 15.0 million shares of common stock from the approximately 11.4 million shares remaining under the current authorization. There is no expiration date associated with this repurchase program. 

 As of March 31, 2016,2022, we held approximately 23.3 million shares as treasury shares. Our current intent is to regularly repurchase shares of our common stock over time based on our cash generation, leverage metrics, and market conditions.


OnIn 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 $2.81$5.05 billion. During fiscal 2016, weCash dividends paid dividends in the amount of $1.433 per share for a totalwere $0.910 and $0.747 during fiscal 2022 and fiscal 2021, respectively. Total dividend paymentpayments amounted to $503.8 million and $388.3 million during fiscal 2022 and fiscal 2021, respectively. A quarterly dividend of $291.1 million. During fiscal 2015, we paid dividends in the amount of $1.425$0.276 per share for a total dividend payment of $286.5 million.  During fiscal 2014, we paid dividends in the amount of $1.417 per share for a total dividend payment of $281.2 million. Onwas declared on May 4, 2016, we declared a quarterly cash dividend of $0.3595 per share, which9, 2022 and will be paid on June 6, 2016,3, 2022 to stockholders of record onas of May 23, 2016 and20, 2022. We expect the total amount of suchaggregate cash dividend is expectedfor the June 2022 quarter to be approximately $77$153.2 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 ongoingincrease our 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 agreementRevolving Credit Facility will be sufficient to meet our currently anticipated cash requirements for at least the next 12 months. However,Our long-term liquidity requirements primarily arise from working capital requirements, interest and principal repayments related to our outstanding indebtedness, capital expenditures, cash dividends, share repurchases, and income tax payments. For additional information regarding our cash requirements see "Note 11. Commitments and Contingencies", "Note 10. Leases", "Note 6. Debt" and "Note 12. Income Taxes" of the notes to our consolidated financial statements. The semiconductor industry is capital intensive.  Inintensive and 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 increase our borrowings under our credit agreementRevolving Credit Facility 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, for share repurchases 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.  We may from time to time seek to refinance certain of our outstanding notes or Convertible Debt through issuances of new notes or convertible debt, tender offers, exchange transactions or open market repurchases. Such issuances, tender offers or exchanges or purchases, if any, will depend on prevailing market conditions, our ability to negotiate acceptable terms, our liquidity position and other factors. There can be no assurance that suchany financing will be available on acceptable terms due to uncertainties resulting from the COVID-19 pandemic, rising interest rates, higher inflation, economic uncertainty, or other factors, 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, 2016, 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, 2016 (dollars in thousands):

(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, 2016, 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 $52.4 million for delivery of wafers in fiscal 2017.
(3)  For purposes of this table we have assumed that the principal of our credit agreement borrowings outstanding at March 31, 2016 will be paid on February 4, 2020, which is the maturity date of such borrowings.
(4)  For purposes of this table we have assumed that the principal of our senior convertible debentures will be paid on February 15, 2025, which is the maturity date of such debentures.
(5)  For purposes of this table we have assumed that the principal of our junior convertible debentures will be paid on December 15, 2037, which is the maturity date of such debentures.
(6)  Total contractual obligations do not include contractual obligations recorded on our 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.
The expected timing of payment of the obligations discussed above is estimated based on current information.  Timing of payments and actual amounts paid may be different depending on the time of receipt of goods or services or changes to agreed-upon amounts for some obligations.


Off-Balance Sheet Arrangements
As of March 31, 2016, we are not involved in any off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of SEC Regulation S-K.

Our investments are intendedAs of March 31, 2022, our long-term debt totaled $7.84 billion. We have no interest rate exposure to establish a high-quality portfolio that preserves principal, meets liquidity needs, avoids inappropriate concentrations, and delivers an appropriate yield in relationship torate changes on 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 $2,564.6millionrate debt, which totaled $6.44 billion as of March 31, 2016 compared2022. We do have interest rate exposure with respect to $2,342.2 millionthe $1.40 billion of our variable interest rate debt outstanding as of March 31, 2015. 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.  We sold a significant portion of our available-for-sale investments during the fourth quarter of fiscal 2016 to finance a portion of the purchase price of our Atmel acquisition which closed on April 4, 2016.

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 defined in Rules 13a-15(e) or 15d-15(e) of the Exchange Act.Act).  Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures arewere 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 CommissionSEC 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, including our principal executive officer and our principal financial officer, 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.U.S. GAAP.  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,U.S. GAAP, 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, 2016,2022, the end of our fiscal year.  Management based its assessment on criteria established in Internal Control Integrated Framework (2013 framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission.  Management's assessment included an 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.U.S. GAAP.  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, 2016,2022, which is included in Part II, Item 9A.on page F-4.

Changes in Internal Control over Financial Reporting
 
During the three months ended March 31, 2016,2022, we transitioned certain of Microsemi's processes to our internal control processes and we expect to transition more of such processes throughout the remainder of calendar year 2022. Other than with respect to our transition of Microsemi to our systems and control environment as described above, during the three months ended March 31, 2022, 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, 2016, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 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, 2016, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Microchip Technology Incorporated as of March 31, 2016 and 2015, and the related consolidated statements of income, comprehensive income, changes in equity, and cash flows for each of the three years in the period ended March 31, 2016 and our report dated May 24, 2016 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


TheTo the Shareholders and the Board of Directors and Stockholders of
Microchip Technology Incorporated and subsidiaries


Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Microchip Technology Incorporated and subsidiaries(the Company) as of March 31, 20162022 and 2015, and2021, the related consolidated statements of income, comprehensive income, changes in equity and cash flows for each of the three years in the period ended March 31, 2016.  2022, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at March 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended March 31, 2022, 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) (PCAOB), the Company's internal control over financial reporting as of March 31, 2022, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated May 20, 2022 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on thesethe Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).PCAOB. 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 includesmisstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence supportingregarding the amounts and disclosures in the financial statements. An auditOur audits also includes assessingincluded evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statement presentation.statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

F-1

Unrecognized tax benefits
Description of the Matter
As more fully described in Note 12 to the consolidated financial statements, the Company operates in a number of tax jurisdictions and its income tax returns are subject to examination by tax authorities in those jurisdictions that may challenge any tax position on these returns. Because the matters challenged by authorities are typically complex and subject to interpretation, their ultimate outcome is uncertain. The Company uses significant judgment in (1) determining whether a tax position’s technical merits are more-likely-than-not to be sustained and (2) measuring the amount of tax benefit that qualifies for recognition. As of March 31, 2022, the Company recognized accrued liabilities for unrecognized tax benefits associated with various tax positions totaling $804.1 million.

Because of the complexity of tax laws and regulations, auditing the recognition and measurement of unrecognized tax benefits requires a high degree of auditor judgment and increased extent of effort, including the involvement of our tax professionals.
How We Addressed the Matter in Our Audit
We obtained an understanding, evaluated the design, and tested the operating effectiveness of controls over the Company’s accounting process for unrecognized tax benefits. This included testing controls over management’s review of the technical merits of tax positions, including the process to measure the financial statement impact of these tax matters.

Our audit procedures included, among others, evaluating the assumptions the Company used to develop its tax positions and related unrecognized tax benefit amounts by jurisdiction and testing the completeness and accuracy of the underlying data used by the Company to calculate its uncertain tax positions. We involved our tax professionals located in the respective jurisdictions to assess the technical merits of the Company’s tax positions and to evaluate the application of relevant tax laws in the Company’s recognition determination. We assessed the Company’s correspondence with the relevant tax authorities and evaluated tax or legal opinions or other third-party advice obtained by the Company. We also evaluated the adequacy of the Company’s disclosures included in Note 12 in relation to these tax matters.

F-2

Convertible debt transactions
Description of the Matter
As described in Note 6 to the consolidated financial statements, the Company privately negotiated several transactions to settle an aggregate of (1) $107.0 million principal amount of its 2015 Senior Convertible Debt, (2) $205.3 million principal amount of its 2017 Senior Convertible Debt and (3) $112.4 million principal amount of its 2017 Junior Convertible Debt. Through these transactions the Company provided holders an aggregate of (1) $424.7 million of cash and (2) 8.8 million shares of the Company’s common stock. The transactions were complex because the Company used significant judgment to estimate the current comparable borrowing rates for otherwise identical non-convertible debt instruments to determine the fair value of the liability components at each transaction date.

Auditing the valuation of the liability components was challenging because the Company used complex valuation methodologies and subjective assumptions, including the expected volatility and credit spread.
How We Addressed the Matter in Our Audit
We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company’s process to estimate the fair value of the liability components of the convertible debt instruments, including controls over management’s review of the valuation model and the significant assumptions used in the calculation.

Our audit procedures included, among others, inspecting the transaction agreements and involving our internal valuation specialist to assist in evaluating the reasonableness of valuation methodologies, models and significant assumptions. We also performed sensitivity analyses to evaluate the reasonableness of certain significant assumptions, including the current comparable borrowing rates. We tested the completeness and accuracy of the underlying data supporting the significant assumptions and estimates. We also evaluated the Company’s financial statement disclosures related to these matters included in Note 6 to the consolidated financial statements.

Definition and Limitations of Internal Control Over Financial Reporting

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.

MICROCHIP TECHNOLOGY INCORPORATED AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTSNotes to Consolidated Financial Statements


1.    SIGNIFICANT ACCOUNTING POLICIESNote 1. Significant Accounting Policies


Nature of Business
 
Microchip Technology Incorporated (Microchip or the Company) develops, manufactures and sells specialized semiconductor productssmart, connected and secure embedded control solutions used by its customers for a wide variety of applications. The Company provides cost-effective embedded control applications. Microchip's product portfolio comprises general purpose and specialized 8-bit, 16-bit, and 32-bit microcontrollers, a broad spectrum of high-performance linear, mixed-signal, power management, thermal management, RF, timing, safety, security, wired connectivity and wireless connectivity devices, as well as serial EEPROMs, Serial Flash memories, Parallel Flash memories and serial SRAM memories. Microchip also licenses Flash-IP solutions that are incorporatedalso offer the advantages of small size, high performance, extreme low power usage, wide voltage range operation, mixed signal integration, and ease of development, thus enabling timely and cost-effective integration of the Company's solutions by its customers in a broad range oftheir end products.

Principles of Consolidation
 
The Company prepares its consolidated financial statements in accordance with U.S. GAAP. The consolidated financial statements include the accounts of Microchip Technology Incorporated and its majority-owned subsidiaries (Microchip or the Company).  The Company owned 100% of the outstanding stock in all of its subsidiaries as of March 31, 2016. As further discussed in Note 2, the Company did not hold 100% of the outstanding common stock of ISSC Technologies Corporation (ISSC) for a period through June 30, 2015. The noncontrolling interest in the Company's net income from ISSC has been excluded from net income attributable to the Company in the Company's consolidated statements of income.  All of the Company's subsidiaries are included in the consolidated financial statements.and controlled subsidiaries.  All significant intercompany accounts and transactions have been eliminated in consolidation. All dollar amounts in the financial statements and tables in these notes, except per share amounts, are stated in millions of U.S. dollars unless otherwise noted.

In August 2021, at our Annual Meeting of Stockholders, our stockholders approved a 2-for-one forward stock split and the amendment and restatement of the Company's Certificate of Incorporation to increase the number of authorized shares of common stock from 450.0 million shares to 900.0 million shares. As a result, each stockholder of record at the close of market on October 4, 2021 received 1 additional share of common stock for every share held. Such shares were distributed after the close of trading on October 12, 2021. All share, equity award, and per share amounts and related shareholders' equity balances presented herein have been adjusted to reflect the stock split.

Revenue Recognition

The Company generates revenue primarily from sales of semiconductor products to distributors and non-distributor customers (direct customers) and, to a lesser extent, from royalties paid by licensees of intellectual property. The Company applies the following five-step approach to determine the timing and amount of revenue recognition: (i) identify the contract with the customer, (ii) identify performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when the performance obligations are satisfied.

Sales to distributors are governed by a distributor agreement, a purchase order, and an order acknowledgment. Sales to distributors do not meet the definition of a contract until the distributor has sent in a purchase order, the Company has acknowledged the order, the Company has deemed the collectability of the consideration to be probable, and legally enforceable rights and obligations have been created. As is customary in the semiconductor industry, the Company offers price concessions and stock rotation rights to many of its distributors. As these are forms of variable consideration, the Company estimates the amount of consideration to which they will be entitled using recent historical data and applying the expected value method. The transaction price is net of all taxes imposed on and concurrent with specific revenue-producing transactions. After the transaction price has been determined and allocated to the performance obligations, the Company recognizes revenue when the earnings processperformance obligations are satisfied. Substantially all of the revenue generated from contracts with distributors is complete, as evidencedrecognized at, or near to, the time risk and title of the inventory transfers to the distributor.

Sales to direct customers are generally governed by a purchase order and an agreementorder acknowledgment. Sales to direct customers usually do not meet the definition of a contract until the direct customer has sent in a purchase order, the Company has acknowledged the order, the Company has deemed the collectability of the consideration to be probable, and legally enforceable rights and obligations have been created.

The final transaction price protection and product return rights, sois

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 saleusage of the Company's products to their end customers and price protection concessions related to market pricing conditions.license occurs.

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, 2016, the Company had approximately $267.2 million of deferred revenue and $83.8 million in deferred cost of sales recognized as $183.4 million of deferred income on shipments to distributors.  At March 31, 2015, the Company had approximately $260.9 million of deferred revenue and $94.8 million in deferred cost of sales recognized as $166.1 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.

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.

For licenses or other technology arrangements without an upgrade period, non-royalty revenue from the 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. In certain limited circumstances, the Company enters into license and other arrangements for technologies that the Company is continuing to enhance and refine or under which it is obligated to provide unspecified enhancements. Under these arrangements, 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.  

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 duringwere immaterial for the fiscal 2016, 2015,years ended March 31, 2022, 2021, and 2014 were immaterial.2020.


Advertising Costs
 
The Company expenses all advertising costs as incurred.  Advertising costs were immaterial for the fiscal years ended March 31, 2016, 20152022, 2021 and 2014.2020.



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.  Renewals or extensions of these assets are expensed as incurred. 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.

Restructuring Charges

Restructuring charges are included within special charges and other, net in the consolidated statements of income and are primarily comprised of employee separation costs, asset impairments, contract exit costs and costs of facility consolidation and closure, including the related gains or losses associated with the sale of owned facilities.  Employee separation costs include one-time termination benefits that are recognized as a liability at estimated fair value at the time of communication to employees, unless future service is required, in which case the costs are recognized ratably over the future service period.  Ongoing termination benefits are recognized as a liability at estimated fair value when the amount of such benefits are probable and reasonably estimable. Contract exit costs include contract termination fees and ROU asset impairments recognized on the cease-use date of leased facilities.  A liability for contract termination fees is recognized in the period in which the Company terminates the contract.

Foreign Currency Translation
 
TheSubstantially all of 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 (loss) income, (expense)net 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 2015,2022, 2021 and 2020, certain foreign subsidiaries acquired as part of the Company's acquisition activities 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 for such entities.


Income Taxes
 
TheAs part of the process of preparing its consolidated financial statements, the Company provides foris required to estimate its income taxes in accordanceeach of the jurisdictions in which it operates.  This process involves estimating its actual current tax exposure together with principles containedassessing temporary differences resulting from differing treatment of items for tax and accounting purposes.  These differences result in ASC Topic 740, Income Taxes. Under these principles, the Company recognizes the amount of income tax payable or refundable for the current year and deferred tax assets and liabilities, forwhich are included within the future tax consequences of eventsCompany's consolidated balance sheets.  The Company must then assess the likelihood that have been recognized in its consolidated financial statements or tax returns.

Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets will be recovered from future taxable income within the relevant jurisdiction and liabilitiesto the extent the Company believes that recovery is not likely, it must establish a valuation allowance.  The Company provided valuation allowances for certain of a change in tax rates is recognized in earnings in the period when the new rate is enacted. Deferredits deferred tax assets are evaluated for future realization and reduced by a valuation allowance ifwhere it is more likely than not that asome portion, or all of such assets, will not be realized. In assessing

F-12

Various taxing authorities in the U.S. and other countries in which the Company does business scrutinize the tax structures employed by businesses.  Companies of a similar size and complexity as the Company are regularly audited by the taxing authorities in the jurisdictions in which they conduct significant operations.  During the fiscal year ended March 31, 2022, various jurisdictions finalized their audits for certain periods. The close of these audits did not have an adverse impact on the financial statements. The Company is currently being audited by the tax authorities in the United States and various foreign jurisdictions for other periods. At this time, the Company does not know what the outcome of these audits will be. The Company records benefits for uncertain tax positions based on an assessment of whether it is more likely than not that deferredthe tax assetspositions will be realized,sustained based on their technical merits under currently enacted law. If this threshold is not met, no tax benefit of the uncertain tax position is recognized. If the threshold is met, the Company considersrecognizes the largest amount of the tax benefit that is more than 50% likely to be realized upon ultimate settlement.

The accounting model related to the valuation of uncertain tax positions requires the Company to presume that the tax position will be examined by the relevant taxing authority that has full knowledge of all available evidence, both positiverelevant information and negative, including its recent cumulative earnings experiencethat each tax position will be evaluated without consideration of the possibility of offset or aggregation with other positions.  The recognition requirement for the liability exists even if the Company believes the possibility of examination by a taxing authority or discovery of the related risk matters is remote or where it has a long history of the taxing authority not performing an exam or overlooking an issue.  The Company will record an adjustment to a previously recorded position if new information or facts related to the position are identified in a subsequent period.  All adjustments to the positions are recorded through the income statement.  Generally, adjustments will be recorded in periods subsequent to the initial recognition if the taxing authority has completed an audit of the period or if the statute of limitation expires.  Due to the inherent uncertainty in the estimation process and expectationsin consideration of the criteria of the accounting model, amounts recognized in the financial statements in periods subsequent to the initial recognition may significantly differ from the estimated exposure of the position under the accounting model.

In December 2017, the TCJA was enacted into law and established a new provision designed to tax low-taxed income of foreign subsidiaries known as global intangible low-taxed income (GILTI). The FASB allows taxpayers to make an accounting policy election of either (i) treating taxes due on GILTI inclusions as a current-period expense when incurred or (ii) recognizing deferred taxes for temporary basis differences that are expected to reverse as GILTI in future availableyears. The Company has made a policy choice to include taxes due on the future GILTI inclusion in taxable income ofwhen incurred.

Cash and Cash Equivalents
 
All highly liquid investments, including marketable securities purchased with a remainingan original maturity to the Company of three months or less when acquired are considered to be cash equivalents.
  
Available-for-Sale Investments
The Company classifies its investments in debt and marketable equity securities as available-for-sale 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 available-for-sale debt securities sold is calculated using the first-in, first-out (FIFO) basis at the individual security level for sales from multiple lots. For sales of marketable equity securities, the Company uses an average cost basis at the individual security level. 

The Company includes within short-term investments 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 4, 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.
Derivative Instruments


Derivative instruments are required to be recorded at fair value as either assets or liabilities in the Company's consolidated balance sheet. The Company's accounting policies for derivative instruments depends on whether the instrument has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship.


The Company does not apply hedge accounting to foreign currency forward contracts. 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.

Interest rate derivative instruments designated as fair value hedges are designed to manage the exposure to interest rate movements and to reduce borrowing costs by converting fixed-rate debt into floating-rate debt. Under these agreements, the Company agrees to exchange, at specified intervals, the difference between the fixed and floating interest amounts calculated by reference to an agreed-upon notional principal amount. For derivative instruments that are designated and qualify as fair value hedges, the gain or loss on the derivatives as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in earnings. The Company evaluates hedge effectiveness at inception and on an ongoing basis. If a derivative is no longer expected to be highly effective, hedge accounting is discontinued. In February 2016, the Company terminated its interest rate derivative instruments.

Inventories
 
Inventories are valued at the lower of cost or marketnet realizable value 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 marketnet realizable 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 ofprojected demand over a 12-month periodperiods that align with demand forecasts used to develop manufacturing plans and inventory build decisions 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 the Company's 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 4030 years

for buildings and building improvements and 35 to 7 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.
 
SeniorLeases

The Company determines if an arrangement is a lease at its inception. Operating lease arrangements are comprised primarily of real estate and Junior Subordinated equipment agreements for which the ROU assets are included in other assets and the corresponding lease liabilities, depending on their maturity, are included in accrued expenses and other current liabilities or other long-term liabilities in the consolidated balance sheets.

Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Operating lease ROU assets also include any initial direct costs and prepayments less lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options.

As the Company's leases generally do not provide an implicit rate, the Company uses its collateralized incremental borrowing rate based on the information available at the lease commencement date, including lease term, in determining the present value of lease payments. Lease expense for these leases is recognized on a straight-line basis over the lease term. The Company accounts for the lease and non-lease components as a single lease component.

Convertible DebenturesDebt
 
TheUpon issuance, the Company separately accounts for the liability and equity components of its seniorConvertible Debt by estimating the fair values of the i) liability component without a conversion feature and junior subordinated convertible debentures in a manner that reflects its nonconvertible debt (unsecured debt) borrowing rate when interest cost is recognized.ii) the conversion feature. 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 itsthe Company's consolidated statements of income. The Convertible Debt is presented as current portion of long-term debt on the balance sheet if the contractual maturity date is within 12 months of the balance sheet date or when the Convertible debt is convertible and the Company does not have the ability to settle the principal portion of its Convertible Debt upon conversion on a long-term basis. As of March 31, 2022, the Company has the ability to settle the principal portion of its Convertible Debt upon conversion on a long-term basis by utilizing proceeds from its Revolving Credit Facility.
F-14


Upon settlement of Convertible Debt instruments, the Company allocates the total consideration between the liability and equity components based on the fair value of the liability component without the conversion feature. The difference between the consideration allocated to the liability component and the net carrying value of the liability component is recognized as an extinguishment loss or gain. The remaining settlement consideration is allocated to the equity component and recognized as a reduction of additional paid-in capital in the Company's consolidated balance sheets. In addition, if the terms of the settlement are different from the contractual terms of the original instrument, the Company recognizes an inducement loss, which is measured as the difference between the fair value of the original terms of the instrument and the fair value of the settlement terms.

Determining the fair value of the liability component without the conversion feature upon issuance and settlement involves estimating the equivalent borrowing rate for a similar non-convertible instrument. Given the values of these transactions, fair value estimates are sensitive to changes in the equivalent borrowing rate conclusions. The measurement of the equivalent borrowing rate requires that the Company make estimates of volatility and credit spreads to align observable market inputs with the instrument being valued.

Lastly, the Company includes the dilutive effect of the shares of its common stock issuable upon conversion of the outstanding senior and junior subordinated convertible debenturesConvertible Debt in its diluted income per share calculation regardless of whether the market price triggers or other contingent conversion features have been met. The Company applies the treasury stock method as it has the intent and abilityhas adopted an accounting policy to settle the principal amountsamount of the senior and junior subordinated convertible debenturesConvertible Debt in cash. This method results in incremental dilutive shares when the average marketfair value of the Company's common stock for a reporting period exceeds the conversion prices per share which were $66.05 and $24.31 for the senior and junior subordinated convertible debentures, respectively, at March 31, 2016 and adjustadjusts as dividends are recorded in the future.


Upon a de-recognition event, the Company estimates the fair value of the liability component and compares that to the carrying amount in order to calculate the appropriate amount of gain or loss. The remaining amounts paid or issued (in the case of non cash consideration in the form of shares of common stock) are recognized as a reduction of additional paid-in-capital. The fair value of the liability component is estimated using the current comparable borrowing rate for an otherwise identical non-convertible debt instrument.Defined Benefit Pension Plans

The Company's estimated rangeCompany maintains defined benefit pension plans, covering certain of liability related to pending litigation isits foreign employees. For financial reporting purposes, net periodic pension costs and pension obligations are determined based on claims that management believesupon a loss is probablenumber of actuarial assumptions, including discount rates for plan obligations, and assumed rates of compensation increases for which an amount or range of loss is estimable.  employees participating in plans. These assumptions are based upon management's judgment and consultation with actuaries, considering all known trends and uncertainties.


Contingencies

In the event that a probable loss cannot be reasonably estimated,ordinary course of business, the Company does not accrue for such losses. Management makesis exposed to various liabilities as a determination as to when a potential loss is reasonably possible based on relevant accounting literatureresult of contracts, product liability, customer claims and then includes appropriate disclosure of the contingency. Asother matters.  Additionally, the Company continuesis involved in a limited number of legal actions, both as plaintiff and defendant.  Consequently, the Company could incur uninsured liability in any of those actions.  The Company also periodically receives notifications from various third parties alleging infringement of patents or other intellectual property rights, or from customers requesting reimbursement for various costs.  With respect to monitor litigationpending legal actions to which the Company is a party and other claims, although the outcomes are generally not determinable, the Company believes that the ultimate resolution of these matters whether deemedwill not have a material asadverse effect on its financial position, cash flows or results of March 31, 2016 oroperations.  Litigation and disputes relating to the semiconductor industry are not its determination could change,uncommon, and the Company is, from time to time, subject to such litigation and disputes.  As a result, no assurances can be given with respect to the extent or outcome of any such litigation or disputes in the future.

The Company accrues for claims and contingencies when losses become probable and reasonably estimable. As of the end of each applicable reporting period, the Company reviews each of its matters and, where it is probable that a liability has been or will be incurred, it accrues for all probable and reasonably estimable losses. Where the Company can reasonably estimate a range of losses it may decide, at some future date,incur regarding such a matter, it records an accrual for the amount within the range that constitutes its best estimate. If the Company can reasonably estimate a range but no amount within the range appears to establish an appropriate reserve.be a better estimate than any other, it uses the amount that is the low end of such range.

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
F-15

allowances and income tax uncertainties after the acquisition date will be recognized through income tax expense or directly in contributed capital.expense.  The aggregate amount of consideration paid by the Company is allocated to net tangible assets and intangible assets based on their estimated fair values as of the acquisition date. The excess of the purchase price over the value of the net tangible assets and intangible assets is recorded to goodwill. 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
 
The Company's intangible assets include 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. Other intangible assets include existing technologies, core and developed technology, in-process research and development, trademarks and trade names, distribution rights and customer-related intangibles. In-process research and development is capitalized until such time as the related projects are completed or abandoned at which time the capitalized amounts will begin to be amortized or written off. Indefinite-lived intangible assets consist of goodwill and in-process research and development intangible assets that have not yet been placed in service. All other intangible assets are definite-lived intangible assets, including in-process research and development assets that have been placed in service, and are amortized over their respective estimated lives, ranging from 1 to 15 years.

The Company is required to perform an impairment review of indefinite-lived intangible assets, including goodwill annually, and more frequently under certain circumstances. The goodwill isIndefinite-lived intangible assets are subjected to this annual impairment 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 two2 reporting units, semiconductor

products and technology licensing. Under theThe Company's impairment evaluation consists of a qualitative goodwill impairment assessment standard,in which management evaluates whether it is more likely than not that goodwill isthe indefinite-lived intangible assets are impaired. If it is determined that it is more likely than not, the Company proceeds with the next step of theperforms a quantitative impairment test, which compares the fair value of the reporting unit or indefinite-lived intangible asset to its carrying value. If the Company determines through the impairment process that goodwillthe indefinite-lived intangible asset has been impaired, the Company will record the impairment charge in its results of operation. Through March 31, 2016,2022, 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-liveddefinite-lived intangible assets may be impaired, the Company evaluates the recoverability and estimated useful lives of such assets. In-process researchIf such indicators are present, recoverability is evaluated based on whether the sum of the estimated undiscounted cash flows attributable to the asset (group) in question is less than their carrying value. If less, the Company measures the fair value of the asset (group) and development is capitalized until such timerecognizes an impairment loss if the related projects are completed or abandoned at which timecarrying amount of the capitalized amounts will begin to be amortized or written off.assets exceeds their respective fair values.
 
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)RSUs have been granted to employees and non-employee members of the Board of Directors.  In the second half of fiscal 2006, theThe Company adopteduses RSUs with a service condition as its primary equity incentive compensation instrument for employees and also grants market-based and performance-based PSUs to executive officers and employees.  The Company also has employee stock purchase plans for eligible employees.
The Company estimates the fair value of share-based payment awards on the date of grantPSUs with a market condition using an option pricing model.  The value of the portion of the award that is ultimately expected to vest is recognized as expense straight-line over the requisite service periods.  The Company has estimated the fair value of each awarda Monte Carlo simulation model as of the date of grant using historical volatility. Share-based compensation cost for RSUs with a service condition or performance-based PSUs is measured on 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 thegrant date of grant requires judgment.  The fair value of RSUs is based on the fair market value of the Company'sCompany’s common stock on the date of grant discounted for expected future dividends.dividends and is recognized as expense on a straight-line attribution method over the requisite service periods. Share-based compensation cost for performance-based PSUs is recognized if and when the Company concludes that it is probable that the
F-16

performance condition will be achieved. The Company usesreassess the Black-Scholes option pricing modelprobability of the performance condition at each reporting period and a cumulative catch-up adjustment is recorded to estimate the fair value of employee stock options and rights to purchase shares under stock purchase 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 tradedshare-based compensation cost for any change 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 impactprobability assessment.
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, 2016, 2015 and 2014 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 $102.9$170.0 million and $104.8 million at March 31, 20162022 and $116.0 million at March 31, 2015.2021, respectively.  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 productproducts 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'sdistributors' 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.GAAP.  Actual results could differ from those estimates.


Business Segments

Operating segments are components of an enterprise about which separate financial information is regularly reviewed by the chief operating decision maker(s) ("CODM")maker (CODM) to assess the performance of the component and make decisions about the resources to be allocated to the component. The Company's ChairmanPresident and Chief Executive Officer and the Company's President and Chief Operating Officer havehas been identified as the CODMs as they jointly manage the Company's worldwide consolidated enterprise.CODM. Based on the Company's structure and manner in which the Company is managed and decisions are made, the Company's business is made up of two2 operating segments, semiconductor products and technology licensing.

In the semiconductor products segment, the Company designs, develops, manufactures and markets microcontrollers, development tools and analog, interface, mixed signalmixed-signal, timing, wired and timingwireless connectivity devices, and memory products. Under the leadership of the CODMs,CODM, the Company is structured and organized around standardized roles and responsibilities based on product groups and functional activities. The Company's product groups are responsible for product research, design and development. The Company's functional activities include sales, marketing, manufacturing, information technology, human resources, legal and finance.

The Company's product groups have similar products, production processes, types of customers and methods for distribution. In addition, the tools and technologies used in the design and manufacture of the Company's products are shared among the various product groups. The Company's product group leaders, under the direction of the CODMs,CODM, define the product roadmaps and team with sales personnel to achieve design wins and revenue and other performance targets. Product group leaders also interact with manufacturing and operational personnel who are responsible for the production, prioritization and planning of the Company's manufacturing capabilities to help ensure the efficiency of the Company's

Subsequent Events

The Company evaluated events after March 31, 2022, and through the date the financial statements were issued, and determined any events or transactions occurring during this period that would require recognition or disclosure are appropriately addressed in these financial statements.

Recently IssuedAdopted Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09-Revenue from Contracts with Customers (Topic 606), 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. In July 2015, the FASB delayed the effective date of the new standard by one year to December 15, 2017, for annual and interim reporting periods beginning after that date. In accordance with the delay, the new standard will be effective forOn April 1, 2021, the Company beginning no later than April 1, 2018.  Early adoption is permitted, but not before the original effective date of December 15, 2016.  The new standard allows for the amendment to be applied either retrospectively to each prior reporting period presented or retrospectively as a cumulative-effect adjustment as of the date of adoption. In March 2016, the FASB issuedadopted ASU 2016-08 - Revenue from Contracts with Customers2019-12-Income Taxes (Topic 606)740): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which clarifies the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU 2016-10 - Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which clarifies the implementation guidance on identifying performance obligations. In May 2016, the FASB issued ASU 2016-12 - Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, which addresses implementation issues that were raised by stakeholders and discussed by the Revenue Recognition Transition Resource Group. As described in the Company's significant accounting policies, the Company defers the revenue and cost of sales on shipments to distributors until the distributor sells the product to their end customer. Upon adoption of ASU 2014-09, ASU 2015-14, ASU 2016-08, ASU 2016-10 and ASU 2016-12, the Company will no longer defer revenue until sale by the distributor to the end customer, but rather, will be required to estimate the effects of returns and allowances provided to distributors and record revenue at the time of sale to the distributor. The Company is currently evaluating the impact that the adoption of the standards may have on its consolidated financial statements and additional changes may be identified. The Company has not elected a transition method.

In April 2015, the FASB issued ASU 2015-03-Simplifying the Presentation of Debt Issuance Costs. This standard amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of as a deferred charge. ASU 2015-03 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015 and requires retrospective application. The Company does not expect this standard to have a material impact on its consolidated financial statements.

In July 2015, the FASB issued ASU 2015-11-Simplifying the Measurement of Inventory. This standard requires that entities measure inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. ASU 2015-11 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016 and is applied prospectively. Early adoption is permitted. The Company does not expect this standard to have a material impact on its consolidated financial statements.

In September 2015, the FASB issued ASU 2015-16-Business Combinations (Topic 805), Simplifying the Accounting for Measurement-Period AdjustmentsIncome Taxes. This standard amends existing guidance enhances and simplifies various aspects of income tax accounting, including requirements related to require acquiring entitieshybrid tax regimes, the tax basis step-up in goodwill obtained in a transaction that is not a business combination, separate financial statements of entities not subject to recognize measurement-period adjustments intax, the reporting period in which the adjustment amounts are determined. The standard also requires entities to present separately on the face of the income statement (or disclose in the notesintraperiod tax allocation exception to the financial statements)incremental approach, ownership changes in investments, interim-period accounting for enacted changes in tax law, and the amount of the adjustment reflectedyear-to-date loss limitation in the current period earnings, by line item, that would have been recognized in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted.interim-period tax accounting. The standard is to be applied prospectively to measurement-period adjustments that occur after the effective date. The Company adopted this standard beginning in the second quarter of fiscal 2016 and the adoption of this standard did not have a material impact on itsthe Company's consolidated financial statements.


Recently Issued Accounting Pronouncements Not Yet Adopted

In August 2020, the FASB issued ASU 2020-06-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity, which simplifies the guidance for certain convertible debt instruments by removing the separation models for convertible debt with a cash conversion feature or convertible instruments with a beneficial conversion feature. As a result, convertible debt instruments will be reported as a single liability instrument with no separate accounting for embedded conversion features. Additionally, ASU 2020-06 requires the application of the if-converted method for calculating diluted earnings per share and the treasury stock method will be no longer available. The Company plans to adopt the standard under the modified retrospective transition method for fiscal 2023. The adoption of this standard is estimated to result in an increase of approximately $105.8 million to our Convertible Debt, to reflect the full principal amount of the Convertible Debt outstanding net of issuance costs, a reduction to additional paid-in capital of approximately $133.6 million, net of estimated income tax effects, to remove the equity component separately recorded for the conversion features associated with the Convertible Debt, a decrease to deferred tax liabilities, and a cumulative-effect adjustment of approximately $52.0 million, net of estimated income tax effects, to increase the opening balance of retained earnings as of April 1, 2022. The adoption of this standard is expected to reduce interest expense by approximately $32.7 million in fiscal 2023. In addition, the required use of the if-converted method in calculating diluted earnings per share is not expected to increase the number of potentially dilutive shares in fiscal 2023 as the Company irrevocably elected cash settlement for the principal amount of its Convertible Debt on April 1, 2022. The Company intends to settle any excess value in shares of its common stock in the event of a conversion.

In November 2015,2021, the FASB issued ASU 2015-17-Income Taxes2021-10-Government Assistance (Topic 740)832): Balance Sheet ClassificationDisclosure by Business Entities about Government Assistance which aims at increasing the transparency of Deferred Taxes.  government assistance received by most business entities.

The guidancesheet and income statement that are affected by the transactions, and significant terms and conditions of the transactions, including commitments and contingencies. If an entity omits any required disclosures because it is legally prohibited, it must disclose that fact. ASU 2021-10 is effective for annual periods, and interim periods within thosefinancial statements issued for annual periods beginning after December 15, 2016, with early adoption permitted. The new guidance was adopted by the Company on a prospective basis in the third quarter for the fiscal year ended March 31, 2016. Prior period amounts in the Company's consolidated balance sheet within this Annual Report on Form 10-K were not adjusted to conform to the new

accounting standard. The adoption of this accounting standard was not material to the Company's consolidated financial statements.

In January 2016, the FASB issued ASU 2016-01-Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. This standard addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. ASU 2016-01 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is not permitted.2021.

2.    BUSINESS ACQUISITIONS
Acquisition of Micrel
On August 3, 2015, the Company acquired Micrel, a publicly traded company based in San Jose, California. The Company paid an aggregate of approximately $430.0 million in cash and issued an aggregate of 8,626,795 shares of its common stock to Micrel shareholders. The number of shares issued in the transaction was subsequently repurchased in the open market during the year ended March 31, 2016. The total consideration transferred in the acquisition, including approximately $4.1 million of non cash consideration for the exchange of certain share-based payment awards of Micrel for stock awards of the Company, and approximately $13.1 million of cash consideration for the payout of vested employee stock awards, was approximately $816.2 million. The Company financed the cash portion of the purchase price using borrowings under its existing credit agreement. As a result of the acquisition, Micrel became a wholly owned subsidiary of the Company. Micrel's business is to design, develop, manufacture and market a range of high-performance analog, power and mixed-signal integrated circuits. Micrel's products address a wide range of end markets including industrial and automotive, wireline communications, enterprise and cloud infrastructure and mobility. Micrel also manufactures custom analog and mixed-signal circuits and provides wafer foundry services for customers which produce electronic systems utilizing semiconductor manufacturing processes as well as micro-electrical mechanical system technologies. The Company's primary reason for this acquisition was to expandfollowing table represents the Company's rangenet sales by contract type (in millions):

Distributors are customers that buy products with the intention of solutions, products and capabilities by extending its served available market.
The acquisition was accounted for under the acquisition method of accounting,reselling them. Distributors generally have a distributor agreement with the Company identified asto govern the acquirer,terms of the relationship. Direct customers are non-distributor customers, which generally do not have a master sales agreement with the Company. The Company's direct customers primarily consist of OEMs and, to a lesser extent, contract manufacturers. Licensees are customers of the operating resultsCompany's technology licensing segment, which include purchasers of Micrelintellectual property and customers that have beenlicensing agreements to use the Company's SuperFlash® embedded flash technology. All of the contract types listed in the table above are included in the Company's consolidated financial statements assemiconductor product segment with the exception of licenses, which is included in the technology licensing segment.

Substantially all of the closing dateCompany's net sales are recognized from contracts with customers.

Semiconductor Product Segment

For contracts related to the purchase of semiconductor products, the Company satisfies its performance obligation when control of the acquisition. Underordered product transfers to the acquisition methodcustomer. The timing of accounting, the aggregatetransfer of control depends on the agreed upon shipping terms with the customer, but generally occurs upon shipment, which is when physical possession of the product has been transferred and legal title of the product transfers to the customer. Payment is generally due within 30 days of the ship date. Payment is generally collected after the Company satisfies its performance obligation. Also, the Company usually does not record contract assets because the Company has an unconditional right to payment upon satisfaction of the performance obligation, and therefore, a receivable is more commonly recorded than a contract asset. Refer to Note 9 for the opening and closing balances of the Company's receivables.

The consideration received from customers is fixed, with the exception of consideration from certain distributors. Certain of the Company's distributors are granted price concessions and return rights, which result in variable consideration. The amount of consideration paid by the Company was allocatedrevenue recognized for sales to Micrel's net tangible assets and intangible assets based on their estimated fair values as of August 3, 2015.  The excessthese certain distributors is adjusted for estimates of the purchase price over the value of the net tangible assetsconcessions and intangible assets was recorded to goodwill. The factors contributing to the recognition of goodwill were based upon the Company's conclusion that there are strategic and synergistic benefitsreturn rights that are expected to be realized fromclaimed. These estimates are based on the acquisition. The goodwill hasrecent history of price concessions and stock rotations.

As of March 31, 2022, the Company had approximately $117.6 million of deferred revenue in the semiconductor product segment, of which $73.2 million is included within accrued liabilities and the remaining is included within other long-term liabilities on the balance sheet. As of March 31, 2021, the Company had an immaterial amount of deferred revenue in the semiconductor product segment. Deferred revenue represents amounts that have been allocatedinvoiced in advance which are expected to be recognized as revenue in future periods.

F-19

Many of the Company’s customer contracts have a duration of less than 12 months, however, a portion of the Company's customer contracts in the semiconductor products reporting segment.  Noneproduct segment contain firmly committed orders beyond 12 months at the time of order. The transaction price the Company expects to receive for non-cancelable commitments in such contracts with remaining performance obligations as of March 31, 2022 for orders with initial durations in excess of 12 months approximates the Company’s fiscal 2022 net sales of which approximately 60.0% is expected to be recognized as net sales over the next 12 months. This is inherently uncertain because the transaction prices include variable consideration which is subject to change based upon market conditions at the time of the goodwillsale and may not be indicative of net sales in future periods.

Technology Licensing Segment

The technology licensing segment includes sales and licensing of the Company's intellectual property. For contracts related to the Micrel acquisitionsale of the Company's intellectual property, the Company satisfies its performance obligation and recognizes revenue when control of the intellectual property transfers to the customer. For contracts related to the licensing of the Company's technology, the Company satisfies its performance obligation and recognizes revenue as usage of the license occurs. The transaction price is deductible for tax purposes.fixed by the license agreement. Payment is collected after the Company satisfies its performance obligation, and therefore no contract liabilities are recorded. The Company retained an independent third-party appraiser to assist management in its valuation; however, the purchase price allocation hasdoes not been finalized. This could result in adjustmentsrecord contract assets due to the fair valuesfact that the Company has an unconditional right to payment upon satisfaction of the assets acquiredperformance obligation, and liabilities assumed,therefore, the useful livesCompany recognizes a receivable instead of intangible assets,a contract asset. Refer to Note 9 for the residual amount allocated to goodwillopening and deferredclosing balances of the Company's receivables.

Basic net income per common share$2.33 $0.67 $1.19 
Diluted net income per common share$2.27 $0.65 $1.11 

The Company computed basic net income per common share based on the present valueweighted average number of common shares outstanding during the expected cash flows to be generated by the respective existing technology or future technology.period. The core and developed technology intangible assets are being amortized commensurate with the expected cash flows used in the initial determination of fair value. In-process technology is capitalized until such time as the related projects are completed or abandoned at which time the capitalized amounts will begin to be amortized or written off.
Customer-related intangible assets consist of Micrel's contractual relationships and customer loyalty related to its distributor and end-customer relationships, and the fair values of the customer-related intangibles were determined based on Micrel's projected revenues. An analysis of expected attrition and revenue growth for existing customers was prepared from Micrel's historical customer information.  Customer relationships are being amortized in a manner consistent with the estimated cash flows associated with the existing customers and anticipated retention rates. Backlog relates to the value of orders not yet shipped by Micrel at the acquisition date, and the preliminary fair values wereCompany computed diluted net income per common share based on the estimated profit associated with those orders. Backlog related assetsweighted average number of common shares outstanding plus potentially dilutive common shares outstanding during the period.

Potentially dilutive common shares from employee equity incentive plans are being recognized commensurate with recognitiondetermined by applying the treasury stock method to the assumed exercise of outstanding stock options and the assumed vesting of outstanding RSUs. The Company's Convertible Debt has no impact on diluted net income per common share unless the average price of the revenue forCompany's common stock exceeds the orders on whichconversion price because the backlog intangible assets were determined.  Amortization expense associated with acquired intangible assets is not deductible for tax purposes.  Thus, approximately $99.7 million was established as a net deferred tax liability forCompany intends to settle the future amortizationprincipal amount of the intangible assets offset by $11.4 millionConvertible Debt in cash upon conversion.  Prior to conversion, the Company will include, in the diluted net income per common share calculation, the effect of net deferred tax assets.the additional shares that may be issued when the Company's common stock price exceeds the conversion price using the treasury stock method.  The following is the weighted average conversion price per share used in calculating the dilutive effect (see Note 6 for details on the Convertible Debt):

The Company continuously evaluates its existing operations in an attempt to identify and realize cost savings opportunities and operational efficiencies. This same approach is applied to businesses that are acquired by the Company and often the operating models of acquired companies are not as efficient as the Company's operating model which enables the Company to realize significant savings and efficiencies. As a result, following an acquisition, the Company will from time to time incur restructuring expenses; however, the Company is often not able to estimate the timing or amount of such costs in advance of the period in which they occur. The primary reason for this is that the Company regularly reviews and evaluates each position, contract and expense against the Company's strategic objectives, long-term operating targets and other operational priorities. Decisions related to restructuring activities are made on a "rolling basis" during the course of the integration of an acquisition whereby department managers, executives and other leaders work together to evaluate each of these expenses and make recommendations. As a result of this approach, at the time of an acquisition, the Company is not able to estimate the future amount of expected employee separation or exit costs that it will incur in connection with its restructuring activities.

The Company incurred costs of $21.1 million, $15.0 million and $18.0 million associated with restructuring certain of its wafer fabrication operations and other acquired operations during the fiscal years ended March 31, 2022, 2021 and 2020, respectively. These wafer fabrication restructuring efforts were substantially completed as of March 31, 2022. The Company's other restructuring activities during the fiscal years ended March 31, 2022, 2021 and 2020 were primarily related to the Company's most recent business acquisitions, and resulted from workforce, property and other operating expense rationalizations as well as combining product roadmaps and manufacturing operations. Additional costs will be incurred in the future as additional synergies or operational efficiencies are identified in connection with the Microsemi transaction, other previous acquisitions, or the restructuring of wafer fabrication operations. The Company is not able to estimate the amount of other such future expenses at this time.

During the fiscal years ended March 31, 2022 and 2020, the Company incurred $12.5 million and $15.7 million, respectively, of net charges related to legal settlements.

All of the Company's restructuring activities occurred in its semiconductor products segment. The Company incurred $70.6 million in costs since the start of the fiscal year ended March 31, 2016 was approximately $116.4 million.2019 in connection with employee separation activities and $3.9 million in connection with contract exit activities. The operationsCompany could incur future expenses as additional synergies or operational efficiencies are identified. Beyond what is already accrued, the Company is not able to estimate future expenses, if any, to be incurred.

The liability for restructuring and other exit costs of Micrel were fully integrated into$16.0 million is included in accrued liabilities and other long-term liabilities, on the Company's operationsconsolidated balance sheet as of November 1, 2015 and as such, cost of sales and operating expenses were no longer segregated as of that date.

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, 2016 and the Company's intent is to hold these investments until these assets are no longer impaired.  For those debt securities not scheduled to mature until after March 31, 2017, such recovery is not anticipated to occur in the next year and these investments have been classified as long-term investments on the consolidated balance sheet.
The amortized cost and estimated fair value of the available-for-sale securitiesdebt resulting in a debt discount of $110.0 million which will be amortized to interest expense using the effective interest method over the term of the debt. Interest on the 2020 Senior Convertible Debt is payable semi-annually in arrears on May 15 and November 15 of each year. In connection with the issuance of the 2020 Senior Convertible Debt, the Company entered into capped call option transactions with several financial institutions at a cost of $35.8 million. The capped call options cover, subject to anti-dilution adjustments, the number of shares of the Company’s common stock initially underlying the 2020 Senior Convertible Debt. Upon conversion of the 2020 Senior Convertible Debt, the Company may exercise the capped call options subject to a cap strike price of $116.79 per share which would reduce the potential dilution to the Company’s common stock or offset any cash payments the Company is required to make in excess of the principal amount of converted notes. Upon conversion of the 2020 Senior Convertible Debt, there will be no economic dilution from the notes until the average market price of the Company’s common stock exceeds the cap price of $116.79 per share as the exercise of the capped call options will offset any dilution from the 2020 Senior Convertible Debt from the conversion price up to the cap price. As these transactions meet certain accounting criteria, the capped call options are recorded as a reduction of stockholders' equity and are not accounted for as derivatives.

Senior Notes

The Company may, at its option, redeem some or all of the applicable series of Senior Notes in the manner set forth in the indenture governing the applicable series of Senior Notes. If the Company experiences a specified change of control triggering event set forth in the indenture governing the applicable series of Senior Notes, the Company must offer to repurchase each of the notes of such series at a price equal to 101% of the principal amount of each note of such series repurchased, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date.

The indenture governing each series of Senior Notes contains certain customary affirmative and negative covenants, including covenants that limit or restrict the Company and its subsidiaries' ability to, among other things, create or incur certain liens, and enter into sale and leaseback transactions, and consolidate with or merge with or into, or convey, transfer or lease all or substantially all of its assets, to another person. These covenants are subject to a number of limitations and exceptions set forth in the indenture governing the applicable series of Senior Notes.

Each series of Senior Notes is guaranteed by certain of the Company's subsidiaries that have also guaranteed the obligations under the Credit Agreement and under the Company’s existing Senior Indebtedness. In the future, each subsidiary of the Company that is a guarantor or other obligor of the Credit Agreement is required to guarantee each series of Senior Notes.

Senior Credit Facilities

In December 2021, the Company amended and restated the Company's Credit Agreement in its entirety. In connection therewith, the collateral securing the Credit Agreement prior to such amendment and restatement was released. The amended and restated Credit Agreement provides for an unsecured revolving loan facility up to $2.75 billion that terminates on December 16, 2026. The Credit Agreement also permits the Company, subject to certain conditions, to add one or more incremental term loan facilities or increase the revolving loan commitments up to $750.0 million.

The revolving loans bear interest, at the Company’s option, at the base rate plus a spread of 0.125% to 0.50%, an adjusted daily simple SOFR rate (or SONIA rate in the case of loans denominated in pounds sterling) plus a spread of 1.125% to 1.50%, or an adjusted term SOFR or adjusted EURIBOR rate (based on one, three or six-month interest periods) plus a spread of 1.125% to 1.50%, in each case, with such spread being determined based on the credit ratings for certain of the Company’s senior, unsecured debt. The base rate means the highest of the prime rate, the federal funds rate plus a margin equal to 0.50% and the adjusted term SOFR rate for a 1-month interest period plus a margin equal to 1.00%. 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
F-28

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 term SOFR or adjusted EURIBOR rates.

The Company's obligations under the Credit Agreement are guaranteed by certain of its subsidiaries meeting materiality thresholds. 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 substantially all assets, make investments, make acquisitions, enter into certain transactions with affiliates, pay dividends or make distributions, repurchase stock, enter into restrictive agreements, 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 total leverage ratio and an interest coverage ratio, all measured quarterly and calculated on a consolidated basis. As of March 31, 2016, by contractual maturity, excluding marketable equity securities of $2.2 million, which have no contractual maturity, are shown below (amounts in thousands).

5.    FAIR VALUE MEASUREMENTS

Accounting rules for fair value clarify that fairFair 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 mutual funds. 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 market1-Observable inputs such as LIBOR-based yield curves, currency spot and forward rates, and credit ratings.quoted prices in active markets;
Derivatives

The Company's derivative assets include interest rate swaps that are classified as Level 2 as the Company uses inputs2-Inputs, other than the quoted prices in active markets, that are observable for the assets. The either directly or indirectly; and
Level 2 derivative assets are primarily valued using standard calculations and models that use readily observable3-Unobservable inputs in which there is little or no market data, as their basis.

Transfers into or out of Level 3 are made if the inputs used in the financial models measuring the fair values of the assets became unobservable or observable, respectively, in the current marketplace. During the year ended March 31, 2016, the Company transferred $2.2 million of corporate debt assets out of Level 3 as the inputs used to value these assets became observable in the current marketplace and are classified as Level 1 as of March 31, 2016. This transfer was effective on October 26, 2015.

During the fourth quarter of fiscal 2016, the Company sold its ARS for proceeds of $12.6 million. At March 31, 2015, the Company's ARS for which auctions were unsuccessful were made up of securities related to the insurance industry valued at $9.8 million with a par value of $22.4 million. During the period the Company held the ARS, the Company estimated the fair value of its ARS, which were 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 ARS were estimated risk free discount rates, liquidity risk premium, and the liquidity horizon. The risk free discount rate applied to these securities was 2.0% 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.
Gains and losses recognized in earnings are credited or charged to other income (expense) on the consolidated statements of income.

Assets Measured and Recorded at Fair Value on a Non-Recurring Basis
The Company's non-marketable equity, cost method investments, and non-financial assets, such as intangible assets, assets held for sale and property, plant and equipment, are recorded at fair value on a non-recurring basis. These assets are subject to fair value adjustments in certain circumstances, for example, when there is evidence of impairment.  

The Company's non-marketable and cost method investments are monitored on a quarterly basis for impairment charges.  The fair values of these investments have been determined as Level 3 fair value measurements because the valuations use unobservable inputs that require management's judgment due to the absence of quoted market prices. There were no impairment charges recognized on these investments during the years ended March 31, 2016 or March 31, 2015. During the year ended March 31, 2014, the Company recognized impairment charges of $0.7 million on these investments. These investments are included in other assets on the consolidated balance sheets.

The fair value measurements related to the Company's non-financial assets, such as intangible assets, assets held for sale and property, plant and equipment are based on available market prices at the measurement date based on transactions of similar assets and third-party independent appraisals, less costs to sell where appropriate. The Company classifies these measurements as Level 2.

6.    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, 20162022 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 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 borrowings at March 31, 2016 approximated book value and are considered Level 2 in the fair value hierarchy described in Note 5. The carrying amount of accounts receivable, accounts payable and accrued liabilities approximates fair value due to the short-term maturity of the amounts and are considered Level 2 in the fair value hierarchy.  


Fair ValueThe fair value of Subordinated Convertible Debentures

the Company's Revolving Credit Facility is estimated using discounted cash flow analysis, based on the Company's current incremental borrowing rates for similar types of borrowing arrangements. 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 Revolving Credit Facility at March 31, 2022 approximated the carrying value excluding debt discounts and debt issuance costs and are considered Level 2 in the fair value hierarchy. The Company measures the fair value of its seniorConvertible Debt and junior subordinated convertible debenturesSenior Notes for disclosure purposes. These fair values are based on observable market prices for these debentures,this debt, which areis traded in less active markets and are therefore classified as a Level 2 fair value measurement, and excludemeasurement.

Note 11. Commitments and Contingencies

Purchase Obligations

The Company has agreements for the purchase of property, plant and equipment and other goods and services including outstanding purchase commitments with the Company's wafer foundries. Commitments for construction or purchases of property, plant and equipment totaled $395.0 million as of March 31, 2022, all of which will be due within the next year. Other purchase obligations and commitments totaled approximately $230.0 million, which includes outstanding purchase commitments with the Company's wafer foundries and other suppliers, for delivery in the fiscal year ended March 31, 2023.

Indemnification Contingencies

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 $178.5 million. There are some licensing agreements in place that do not specify indemnification limits. As of March 31, 2022, the Company had not recorded any liabilities related to these indemnification obligations and the Company believes that any amounts that
F-33

it may be required to pay under these agreements in the future will not have a material adverse effect on its financial position, cash flows or results of operations.

Warranty Costs and Product Liabilities

The Company accrues for known product-related claims if a loss is probable and can be reasonably estimated. During the periods presented, there have been no material accruals or payments regarding product warranty or product liability. Historically, the Company has experienced a low rate of payments on product claims. Although the Company cannot predict the likelihood or amount of any future claims, the Company does not believe these claims will have a material adverse effect on its financial condition, results of operations or liquidity.

Legal Matters

In the ordinary course of the Company's business, it is exposed to various liabilities as a result of contracts, product liability, customer claims, governmental investigations and other matters. Additionally, the Company is involved in a limited number of legal actions, both as plaintiff and defendant. Consequently, the Company could incur uninsured liability in any of those actions.  The Company also periodically receives notifications from various third parties alleging infringement of patents or other intellectual property rights, or from customers requesting reimbursement for various costs. With respect to pending legal actions to which the Company is a party and other claims, although the outcomes are generally not 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, governmental investigations and disputes relating to the semiconductor industry are not uncommon, and the Company is, from time to time, subject to such litigation, governmental investigations and disputes.  As a result, no assurances can be given with respect to the extent or outcome of any such litigation, governmental investigations or disputes in the future.

In connection with its acquisition of Microsemi, which closed on May 29, 2018, the Company became involved with the following legal matters:

Federal Shareholder Class Action Litigation.  Beginning on September 14, 2018, the Company and certain of its officers were named in 2 putative shareholder class action lawsuits filed in the United States District Court for the District of Arizona, captioned Jackson v. Microchip Technology Inc., et al., Case No. 2:18-cv-02914-ROS and Maknissian v. Microchip Technology Inc., et al., Case No. 2:18-cv-02924-JJT. On November 13, 2018, the Maknissian complaint was voluntarily dismissed.  On December 11, 2018, the Court issued an order appointing the lead plaintiff in the Jackson matter. An amended complaint was filed on February 22, 2019. The complaint is allegedly brought on behalf of a putative class of purchasers of Microchip common stock between March 2, 2018 and August 9, 2018.  The complaint asserts claims for alleged violations of the federal securities laws and alleges that the defendants issued materially false and misleading statements and failed to disclose material adverse facts about the Company’s business, operations, and prospects during the putative class period.  The complaint seeks, among other things, compensatory damages and attorneys’ fees and costs on behalf of the putative class.  Defendants filed a motion to dismiss the amended complaint on April 1, 2019, which motion was granted in part and denied in part on March 11, 2020. Plaintiff filed a motion for class certification, which was granted by the Court. Discovery is ongoing. The Company and its officers have reached an agreement to settle the litigation. On March 11, 2022, the Court entered an order granting preliminary approval of the proposed settlement. The settlement remains subject to final court approval, and a settlement hearing is scheduled for June 22, 2022.

Derivative Litigation. On January 22, 2019, a shareholder derivative lawsuit was filed against certain of the Company’s officers and directors in the Superior Court of Arizona for Maricopa County, captioned Reid v. Sanghi, et al., Case No. CV2019-002389. The Company is named as a nominal defendant. The complaint generally alleges that defendants breached their fiduciary duties by, among other things, purportedly failing to conduct adequate due diligence regarding Microsemi prior to its acquisition, misrepresenting the Company’s business prospects and health, and engaging in improper practices, and further alleges that certain defendants engaged in insider trading. The complaint asserts causes of action for breach of fiduciary duty, waste, and unjust enrichment and seeks unspecified monetary damages, corporate governance reforms, equitable and/or injunctive relief, restitution, and attorneys’ fees and costs. An amended complaint was filed on February 28, 2020, and a second amended complaint was filed on July 27, 2020. The Company’s Audit Committee filed a motion to dismiss.On April 4, 2022, the Court entered an order denying the Audit Committee’s motion to dismiss. The case is proceeding. On August 5, 2021, a second shareholder derivative lawsuit was filed against certain of the Company’s officers and directors in the Superior Court of Arizona for Maricopa County, captioned Dutrisac v. Sanghi, et al., Case No. CV2021-012459. The Company is named as a nominal defendant. The complaint asserts substantially the same allegations as those in the Reid case. The complaint asserts causes of action for breaches of fiduciary duty, insider selling, unjust
F-34

enrichment, waste of corporate assets, indemnification, and contribution and seeks unspecified monetary damages, equitable and/or injunctive relief, disgorgement, corporate governance reforms, and attorneys’ fees and costs. The Company's Audit Committee filed a motion to dismiss. On April 7, 2022, the Court entered an order denying the Audit Committee’s motion to dismiss. The case is proceeding.

Governmental Investigations. The SEC informed the Company in October 2018 that it was investigating matters relating to the Company's acquisition of Microsemi. The Company believes that the investigation relates to distribution channel issues and business practices at Microsemi and the allegations made by the plaintiffs in the Peterson v. Sanghi lawsuit which was described in the Company’s prior filings on Form 10-Q and Form 10-K and which lawsuit has been settled and dismissed. The Department of Justice, which was also investigating those matters, informed the Company in February 2021 that its investigation is closed and that no further action will be taken.

As a result of its acquisition of Atmel, which closed April 4, 2016, the Company became involved with the following legal matters:

Continental Claim ICC Arbitration. On December 29, 2016, Continental Automotive GmbH ("Continental") filed a Request for Arbitration with the ICC, naming as respondents the Company's subsidiaries Atmel Corporation, Atmel SARL, Atmel Global Sales Ltd., and Atmel Automotive GmbH (collectively, "Atmel").  The Request alleges that a quality issue affecting Continental airbag control units in certain recalled vehicles stems from allegedly defective Atmel application specific integrated circuits ("ASICs").  Continental seeks to recover from Atmel all current and future costs and damages incurred as a result of the vehicle manufacturers’ airbag control unit-related recalls, with current costs and damages alleged to be about $82.0 million to date. The Company's Atmel subsidiaries intend to defend this action vigorously.

Southern District of New York Action by LFoundry Rousset ("LFR") and LFR Employees. On March 4, 2014, LFR and Jean-Yves Guerrini, individually and on behalf of a putative class of LFR employees, filed an action in the United States District Court for the Southern District of New York (the "District Court") against the Company's Atmel subsidiary, French subsidiary, Atmel Rousset S.A.S. ("Atmel Rousset"), and LFoundry GmbH ("LF"), LFR's German parent. The case purports to relate to Atmel Rousset's June 2010 sale of its wafer manufacturing facility in Rousset, France to LF, and LFR's subsequent insolvency, and later liquidation, more than three years later. The District Court dismissed the case on August 21, 2015, and the United States Court of Appeals for the Second Circuit affirmed the dismissal on June 27, 2016. On July 25, 2016, the plaintiffs filed a notice of appeal from the District Court's June 27, 2016 denial of their motion for relief from the dismissal judgment. On May 19, 2017, the United States Court of Appeals for the Second Circuit affirmed the June 27, 2016 order dismissing the case.

Individual Labor Actions by former LFR Employees. In June 2010, Atmel Rousset sold its wafer manufacturing business in Rousset, France to LFoundry GmbH ("LF"), the German parent of LFoundry Rousset ("LFR"). LFR then leased the Atmel Rousset facility to conduct the manufacture of wafers. More than three years later, LFRbecame insolvent and later liquidated. In the wake of LFR's insolvency and liquidation, over 500 former employees of LFR filed individual labor actions against Atmel Rousset in a French labor court, and in 2019 a French labor court dismissed all of the employees’ claims against Atmel Rousset. Plaintiffs have filed appeals requesting reconsideration of the earlier dismissals. Furthermore, these same claims have been filed by this same group of employees in a regional court in France against Microchip Technology Incorporated and Atmel Corporation. The Company, and the other defendant entities, believe that each of these actions is entirely devoid of merit, and, further, that any assertion by any of the Claimants of a co-employment relationship with any of these entities is based substantially on the same specious arguments that the Paris Commercial Court summarily rejected in 2014 in related proceedings. The defendant entitiestherefore intend to defend vigorously against each of these claims. Additionally, complaints have been filed in a regional court in France on behalf of the same group of employees against Microchip Technology Rousset, Atmel Switzerland Sarl, Atmel Corporation and Microchip Technology Incorporated alleging that the sale of the Atmel Rousset production unit to LF was fraudulent and should be voided. These claims are specious and the defendant entities therefore intend to defend vigorously against these claims.

The Company accrues for claims and contingencies when losses become probable and reasonably estimable. As of the end of each applicable reporting period, the Company reviews each of its matters and, where it is probable that a liability has been or will be incurred, the Company accrues for all probable and reasonably estimable losses. Where the Company can reasonably estimate a range of losses it may incur regarding such a matter, the Company records an accrual for the amount within the range that constitutes its best estimate. If the Company can reasonably estimate a range but no amount within the range appears to be a better estimate than any other, the Company uses the amount that is the low end of such range. As of March 31, 2022, the Company's estimate of the aggregate potential liability that is possible but not probable is approximately $100.0 million in excess of amounts accrued.

(1) The release of prior year tax positions during fiscal 2016 increased each of the basic and diluted net income per common share by $0.06. The release of prior year tax positions during fiscal 2015 increased the basic and diluted net income per common share by $0.16 and $0.15, respectively. The release of prior year tax positions during fiscal 2014 increased each of the basic and diluted net income per common share by $0.07.


The foreign tax rate differential benefit primarily relates to the Company's operations in Thailand Cayman and Ireland. The Company's Thailand manufacturing operations are currently subject to 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,between fiscal 2023 and 2030, however, the Company actively seeks to obtain 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 benefitsbenefit derived from these tax holidays approximated $6.0 million, $12.4$22.5 million and $16.8$11.1 million in fiscal 2016, 20152022 and 2014,fiscal 2021, respectively.

No U.S. income taxes have been provided on substantially all The impact of the filing basis undistributed foreign earnings and profits of approximately $3.4 billion as of March 31, 2016 since the Company has the ability and intent to permanently reinvest these amounts. If such earnings were repatriated, additional tax expense may result, although the calculation of such additional taxes is not practicable.

During the year ended March 31, 2016, the Company effectively settled several open tax positions related to the examination ofholidays during fiscal years 2012 and 2011 by the U.S. Internal Revenue Service (IRS).  In addition, the Company benefited from the expiration2022 increased each of the statutebasic and diluted net income per common share by $0.04.

In addition to the deferred tax assets listed above, the Company has unrecorded tax benefits of $47.3 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.
In assessing whether it is more likely than not that deferred tax assets will be realized, the Company considers all available evidence, both positive and negative, including its recent cumulative earnings experience and expectations of future available taxable income of the appropriate character by taxing jurisdiction, tax attribute carryback and carryforward periods available to them for tax reporting purposes, and prudent and feasible tax planning strategies.


 A summary of additions and deductions related to the valuation allowance for deferred tax asset accounts for the years ended March 31, 2022, 2021 and 2020 follows (amounts in millions):

The Company had federal, state and foreign NOL carryforwards with an estimated tax effect of $99.5$77.0 million available at March 31, 2016.2022.  The federal, state and stateforeign NOL carryforwards expire at various times between 2016fiscal 2023 and 2035.fiscal 2042, of which a portion of the NOL carryforwards do not expire. 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, 2016, the Company has provided a valuation allowance of $53.2 million.  The Company also hashad state tax credits with an estimated tax effect of $80.5$164.4 million available at March 31, 2016.2022.  These state tax credits expire at various times between 2016fiscal 2023 and 2036.fiscal 2042. 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 $55.6 million.  The Company hashad capital loss carryforwards with an estimated tax effect of $5.7$9.8 million available at March 31, 2016.2022. These capital loss carryforwards begin to expire in 2020. The Company believes that it is more likely than not that the full benefit from these capital losses will not be realized, and therefore has provided a valuation allowance of $5.7 million.fiscal 2023. The Company had U.S foreign tax credits with an estimated tax effect of $25.8$0.7 million that expire available at various times between 2016 and 2026.  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 $25.2 million.  At March 31, 2016, the2022. These foreign tax credits begin to expire in fiscal 2023. The Company had credits for increasing research activity in the amount of $72.7$79.5 million that available at March 31, 2022. These credits begin to expire in fiscal 2023. The Company had U.S. prior year minimum tax credits in the amount of $0.1 million available at March 31, 2022. The Company had refundable tax credits in foreign
F-37

jurisdictions of $42.0 million available at March 31, 2022. The Company had withholding tax credits in foreign jurisdictions of $19.9 million available at March 31, 2022. These credits expire at various times between 2022fiscal 2023 and 2036. Atfiscal 2025.

The Company intends to invest substantially all of its foreign subsidiary earnings, as well as its capital in its foreign subsidiaries, indefinitely outside of the U.S. in those jurisdictions in which the Company would incur significant, additional costs upon repatriation of such amounts.  It is not practical to estimate the additional tax that would be incurred, if any, if the permanently reinvested earnings were repatriated.

The enactment of the TCJA imposed a tax on all previously untaxed earnings of non-U.S. subsidiaries of U.S. corporations. Due to this change, the jurisdiction in which our cash is at any given point in time no longer has a significant impact on our liquidity.  Future distributions of a significant portion of our non-U.S. assets to the U.S. will no longer be subject to U.S. federal taxation.  We intend to invest substantially all of our foreign subsidiary earnings, as well as our capital in our foreign subsidiaries, indefinitely outside of the U.S. in those jurisdictions in which we would incur significant, additional costs upon repatriation of such amounts. During fiscal 2018, we recognized a one-time transition tax on accumulated unrepatriated foreign earnings, of which we expected cash payments of approximately $290.3 million. This tax is payable over a period of eight years, with 8% of the transition tax payable each year for fiscal 2019 through fiscal 2023, and 15%, 20%, and 25%, respectively, payable during fiscal 2024, fiscal 2025, and fiscal 2026. As of March 31, 2016, the Company had $4.3 million of alternative minimum2022, our transition tax credits that do not expire. In addition, the Company had $20.0payable was $197.4 million, of withholding tax credits that expire at various times between 2022 and 2024 in foreign jurisdictions. The Company believes itwhich $23.2 million is more likely than not thatpayable within the benefit from these credits will not be fully realized and has provided a valuation allowance of $20.0 million.next 12 months.

During the year ended March 31, 2016, the H.R. 2029 "Protecting Americans from Tax Hikes Act of 2015" was signed into law which extended certain business tax provisions through December 31, 2019, including IRC section 954(c)(6) dealing with the application of Subpart F to certain inter-company payments among controlled foreign corporations. The expiration of section 954(c)(6) and the other expired provisions could have a material impact on the Company's consolidated results of operations subsequent to the year ended March 31, 2020.


The Company recognizes interest and penalties related to unrecognized tax benefits through income tax expense. 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 20112007 and later tax years remain effectively open for examination by tax authorities.  The IRS is currently auditing Microchip'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 2008.2007.
 
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 couldwould 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, additionalthe tax paymentspositions are more likely than not.not to be sustained based on the technical merits.  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 lawlaws 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 could 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

14.    1.625% SENIOR SUBORDINATED CONVERTIBLE DEBENTURES
In February 2015, the Company issued $1,725.0 million principal amount of 1.625% senior subordinated convertible debentures due February 15, 2025. The debentures are subordinated to the Company's senior debt, including amounts borrowed under its amended credit facility, but are senior to the Company's outstanding 2.125% junior subordinated convertible debentures. The debentures are convertible, subject to certain conditions, into cash, shares of the Company's common stock or a combination thereof, at the Company's election, at an initial base conversion rate of 14.5654 shares of common stock per $1,000 principal amount of debentures, representing an initial base conversion price of approximately $68.66 per share of common stock.  As a result of cash dividends paid since the issuance of the debentures, the conversion rate has been adjusted to 15.1396 shares of common stock per $1,000 of principal amount of debentures, representing a base conversion price of approximately $66.05 per share of common stock. In addition, if at the time of conversion the applicable price of the Company's common stock exceeds the base conversion price, the conversion rate will be increased by up to an additional initial base conversion rate of 7.2827 shares of common stock per $1,000 principal amount of debentures, as determined pursuant to a specified formula. As a result of cash dividends paid since the issuance of the debentures, the maximum number of additional shares that may be issued if the stock price of the Company's common stock exceeds the base conversion price has been adjusted to 7.5698 shares of common stock per $1,000 principal amount of debentures. However, in no event will the conversion rate exceed 20.3915 (adjusted to 21.1954 as a result of cash dividends paid since the issuance of the debentures) shares of common stock per $1,000 principal amount of debentures. The Company received net proceeds of approximately $1,694.7 millionis currently under income tax examination in various tax jurisdictions in which it operates. The years under examination range from the issuance of its senior subordinated convertible debentures after deduction of issuance costs of approximately $30.3 million. The $30.3 million in issuance costs was split between a debt component of $20.4 million and an equity component of $9.9 million.  The $20.4 million in debt issuance costs is recorded in other assets and is being amortized using the effective interest method over the term of the debentures.

Prior to the close of business on the business day immediately preceding November 15, 2024, the debentures will be convertible at the option of the debenture holders only upon the satisfaction of specified conditions and during certain periods. Thereafter until close of business on the second scheduled trading day immediately preceding February 15, 2025, the debentures will be convertible at the option of the debenture holders at any time regardless of these conditions. Accrued and unpaid interest will be considered fully paid upon settlement of shares.
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, 2016 and March 31, 2015 was $564.9 million.  The estimated fair value of the liability component of the debentures at the issuance date was $1,160.1 million resulting in a debt discount of $564.9 million.  The unamortized debt discount was $490.3 million at March 31, 2016 and $559.3 million at March 31, 2015.  The remaining period over which the unamortized debt discount will be recognized as non-cash interest expense is 8.87 years.fiscal 2007 through fiscal 2020. In fiscal 2016, the Company recognized $42.6 million in non-cash interest expense related to the amortization of the debt discount compared to $5.7 million in fiscal 2015.  The Company recognized $28.0 million of interest expense related to the 1.625% coupon on the debentures in fiscal 2016 compared to $3.8 million in fiscal 2015. The effective interest rate of the debentures is 5.9%.

15.    2.125% JUNIOR SUBORDINATED CONVERTIBLE DEBENTURES

In February 2015, the Company acquired $575.0 million in aggregate principal amount of its 2.125% junior subordinated convertible debentures for an aggregate purchase price of $1,134.6 million, based on market value. The payment was allocated between the liability ($238.3 million) and equity ($896.3 million) components of the convertible debentures, using the equivalent rate that reflected the borrowing rate for a similar non-convertible debt prior to the retirement. The transaction resulted in a loss on retirement of convertible debentures of approximately $50.6 million, which represented the difference between the fair value of the liability component at time of repurchase and the sum of the carrying values of the debt component and any unamortized debt issuance costs.



The Company's remaining $575.0 million 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 (including the Company's senior subordinated convertible debentures) 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 cash, shares of the Company's common stock or a combination thereof, at the Company's election, 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, 2016, the holders of the debentures had the right to convert their debentures between April 1, 2016 and June 30, 2016 because for at least 20 trading days during the 30 consecutive trading day period ending on March 31, 2016, the Company's common stock had a last reported sale price greater than 130% of the conversion price. As of March 31, 2016,some jurisdictions, the Company has classifiedreceived tax assessments in excess of established reserves. The Company is contesting these tax assessments, and will continue to do so, including pursuing all available remedies such as appeals and litigation, if necessary. During fiscal 2022, additional assessments were received for these issues and the junior subordinated convertible debentures as long-term on the consolidated balance sheets as the Company has the intent and ability to refinance the obligation on a long-term basis. As of March 31, 2016, 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 41.1350 shares of common stock per $1,000 of principalCompany’s position remains unchanged.

The total amount of debentures, representing a conversion price of approximately $24.31 per share of common stock. The if-converted value of the debentures exceeded the principal amount by $565.1 million at March 31, 2016. The debentures include a contingent interest mechanism that begins in December 2017. The terms of the contingent interest include a 0.25% additional interest rate if the debentures are trading at less than $400 and a 0.5% additional interest rate if the debentures are trading at greater than $1,500. Based on the current trading price of the debentures, the contingent interest rate beginning in December 2017 would be 0.5% of the average trading price.
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 were both initially recorded at fair value.  The carrying value of the equity component at March 31, 2016 and March 31, 2015gross unrecognized tax benefits was $411.2 million.  The estimated fair value of the liability component of the debentures at the issuance date was $163.8 million, resulting in a debt discount of $411.2 million.  The unamortized debt discount was $378.3 million at March 31, 2016 and $383.7 million at March 31, 2015.  The remaining period over which the unamortized debt discount will be recognized as non-cash interest expense is 21.75 years.  In the years ended March 31, 2016, 2015 and 2014, the Company recognized $5.4 million, $9.1$804.1 million and $9.0 million, respectively, in non-cash interest expense related to the amortization of the debt discount.  The Company recognized $12.2 million, $22.8 million and $24.4 million of interest expense related to the 2.125% coupon on the debentures in fiscal 2016, 2015 and 2014, respectively. The effective interest rate of the debentures is 9.1%.

16.CREDIT FACILITY

In February 2015, the Company amended its existing $2.0 billion credit agreement by increasing the revolving credit facility to $2.555 billion and removing the term loan portion of the agreement. The new credit agreement includes two tranches. One tranche consists of bank commitments through February 2020 and another tranche consists of bank commitments through June 2018, the maturity date of the original credit agreement. The increase option permitting the Company, subject to certain requirements, to arrange with existing lenders or new lenders to provide up to an aggregate of $300 million in additional commitments, was also adjusted to $249.4 million. The credit agreement provides for a $125 million foreign currency sublimit, a $25 million letter of credit sublimit and a $25 million swingline loan sublimit. The amended credit agreement was accounted for as a modification and as such any remaining unamortized deferred costs associated with the prior credit agreement was associated with the new agreement since the borrowing capacity was increased. At March 31, 2016, $1,052.0 million of revolving credit facility borrowings were outstanding under the credit agreement compared to $462.0 million at March 31, 2015.

In December 2015, the Company secured additional revolving credit commitments of $219 million from various banks in the February 2020 tranche under the increase option of the credit agreement, bringing its revolving credit facility to $2.774 billion. The remaining increase option was $30.4$826.3 million as of March 31, 2016.

In December 2015,2022, and March 31, 2021, respectively, of which $692.3 million and $720.5 million is estimated to impact the Company amendedCompany's effective tax rate, if recognized. Unrecognized tax benefits may change in the Maximum Total Leverage Rationext 12 months due to expiration of statutes of limitation, changes in Section 6.11the Company’s judgment about the level of its existing credit agreement to allow the Total Leverage Ratio to be temporarily increased to 5.00 to 1.00 for a perioduncertainty, status of four consecutive quarters in conjunction with a Permitted Acquisition occurring during the first of the four quarters. The Total Leverage Ratio then decreases to 4.75 to 1.00 for three consecutive quarters, finally returning to the stated 4.50 to 1.00 Total Leverage Ratio of the credit agreement after a period of seven consecutive fiscal periods.tax examinations, and legislative changes. The Company can elect to use this special feature, also referred to as an Adjusted Covenant Period, no more than two times during the term of the credit agreement and also can terminate an Adjusted Covenant Period earlier than the seven consecutive quarters allowed.



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 quarters (in the case of the 2018 tranche revolving loans) or the consolidated senior leverage ratio (in the case of the 2020 tranche revolving loans). 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 Companyestimates that it is also obligated to pay other customary 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 $18.9 million in fiscal 2016, approximately $19.9 million in fiscal 2015 and approximately $14.6 million in fiscal 2014. Principal, together with all accrued and unpaid interest, is due and payable on the respective tranche maturity date, which is June 27, 2018 and February 4, 2020. The weighted average interest rate on short-term borrowings outstanding at March 31, 2016 related to the credit agreement was 1.94%. 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 are 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 consolidated senior and total leverage ratios and a consolidated interest coverage ratio. At March 31, 2016, 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.

17.CONTINGENCIES

In the ordinary course of the Company's business, the Company is involved in a limited number of legal actions, both as plaintiff and defendant. Consequently, the Company could incur uninsured liability in any of those actions. The Company also periodically receives notifications from various third parties alleging infringement of patents or other intellectual property rights. With respect to pending legal actions to which the Company is a party, although the outcomes of these actions are generally not determinable, the Company believes that the ultimate resolution of these matters will not harm its business and will not have a material adverse effect on its financial position, cash flows or results of operations.  However, if an unfavorable ruling were to occur in any of the legal proceedings described in Note 28 or in other legal proceedings that were not deemed material to the Company as of the date hereof, then such legal proceedings could have a material adverse effect on the Company's financial position, cash flows or results of operations. Litigation relating to the semiconductor industry is not uncommon, and the Company is, from time to time, subject to such litigation.  As a result, 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. Thereasonably 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 $142.7 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 obligationsunrecognized tax benefits as of March 31, 2016.2022, could decrease by approximately $10.0 million in the next 12 months. Positions that may be resolved include various U.S. and non-U.S. matters.


18.STOCK REPURCHASE ACTIVITY


In December 2007,July 2015, in Altera Corp. v. Commissioner, the U.S. Tax Court issued an opinion related to the treatment of stock-based compensation expense in an intercompany cost-sharing arrangement. In the July 2015 ruling, the Tax Court concluded that the sharing of the cost of employee stock compensation in a company’s cost-sharing arrangement was invalid under the U.S. Administrative Procedures Act. In June 2019, a panel of the Ninth Circuit of the U.S. Court of Appeals reversed this decision. In July 2019, Altera petitioned the U.S. Court of Appeals for the Ninth Circuit to hold an en banc rehearing of the case. In November 2019, the en banc rehearing petition was denied, and Altera has asked the Supreme Court for a judicial review. In June 2020, the U.S. Supreme Court declined to issue a writ of certiorari in Altera v Commissioner, leaving intact the decision reached by the Ninth Circuit of the U.S. Court of Appeals. Based on the Ninth Circuit Opinion, the Company announced that its Boardrecorded a cumulative income tax expense of Directors had authorized the repurchase of up to 10.0$22.2 million shares of its common stock in the open market or in privately negotiated transactions.  Asas of March 31, 2015, the Company had repurchased 7.5 million shares under this authorization for $234.7 million.  In May 2015, the Company's Board of Directors authorized an increase to the existing share repurchase program to 20.0 million shares of common stock from the approximately 2.5 million shares remaining under the prior authorization. During fiscal 2016, the Company repurchased 8.6 million shares under this authorization for $363.8 million. In January 2016, the Company's Board of Directors authorized an increase to the existing share repurchase program to 15.0 million shares of common stock from the approximately 11.4 million shares remaining under the prior authorization. There is no expiration date associated with this repurchase program. During the years ended March 31, 2015 and 2014, the Company did not purchase any of its shares of common stock. 2022.


19.EMPLOYEE BENEFIT PLANSNote 13. 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.  Defined Benefit Plans

The Company has a discretionary matching contribution program. All matchesdefined benefit pension plans that cover certain French and German employees.

The Company grants RSUs with a service condition and PSUs under the 2004 plan. The Company uses RSUs with a service condition as its primary equity incentive compensation instrument for employees. The Company grants PSUs to a group of executive officers and employees. For the market-based PSUs, the number of shares of our common stock expected to be received at vesting will range from 0% to 200% of the target grant amount based on the TSR of our common stock measured against the TSR of a defined peer group of companies over the applicable two-year or three-year measurement period. TSR is a measure of the stock price appreciation plus any dividends paid in the performance period. For the performance-based PSUs, the number of shares of our common stock expected to vest will range from 0% to 200% of the target grant amount based on our three-year cumulative non-GAAP operating margin percentage. Under the 2004 plan, 64,389,717 shares of common stock have been authorized for issuance and 11,091,259 shares of common stock remain available for future grants as of March 31, 2022.

23.DERIVATIVE INSTRUMENTS

Freestanding Derivative Forward Contracts

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.  Net gains due to foreign exchange rate fluctuations after the effects of hedging activity were $0.7 million during fiscal 2016, compared to net losses of

$7.7 million during fiscal 2015 and net gains of $0.4 million during fiscal 2014. As of March 31, 2016 and 2015, the Company had no foreign currency forward contracts outstanding. The Company recognized an immaterial amount of net
realized gains and losses on foreign currency forward contracts in the years ended March 31, 2016, 2015 and 2014. Gains and losses from changes in the fair value of these foreign currency forward contracts and foreign currency exchange rate fluctuations are credited or charged to other income (expense). The Company does not apply hedge accounting to its foreign currency derivative instruments.

Fair Value Hedges

For derivative instruments that are designated and qualify as fair value hedges, the gain or loss on the derivatives as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in earnings. Interest rate derivative instruments designated as fair value hedges are designed to manage the exposure to interest rate movements and to reduce borrowing costs by converting fixed-rate debt into floating-rate debt. Under these agreements, the Company agrees to exchange, at specified intervals, the difference between the fixed and floating interest amounts calculated by reference to an agreed-upon notional principal amount.

In March 2015, the Company entered into ten-year fixed-to-floating interest rate swap agreements designated as fair value hedges of the changes in fair value of a portion of the Company's fixed-rate 1.625% senior subordinated convertible debentures due to changes in the LIBOR swap rate, the designated benchmark interest rate. The Company pays variable interest equal to the three-month LIBOR minus 53.6 basis points and it receives a fixed interest rate of 1.625%. The notional amount of these contracts outstanding at March 31, 2015 was $431.3 million, representing 25% of the principal amount of the senior subordinated convertible debentures.

In February 2016, the Company terminated its interest rate swap agreements. Upon termination, the contracts were in an asset position, resulting in cash receipts of approximately $25.7 million, which included $3.7 million of accrued interest. The gain from terminating the interest rate swap agreements increased the outstanding balance of the 1.625% senior convertible debentures and is being amortized as a reduction of interest expense over the remaining life of the debentures. The cash flows from the termination of these interest rate swap agreements have been reported as operating activities in the consolidated statements of cash flows.

The following table summarizes the location and fair value amounts of derivative instruments reported in the consolidated balance sheets at March 31, 2015 (amounts in thousands):

The Company computed basic earnings per common share attributable to its stockholders using net income available to common stockholders and the weighted average number of commonpurchase shares outstanding during the period. The Company computed diluted earnings per common share attributable to its stockholders using net income available to stockholders and the weighted average number of common shares outstanding plus potentially dilutive common shares outstanding during the period.

Potentially dilutive common shares from employee equity incentive plans are determined by applying the treasury stock method to the assumed exercise of outstanding stock options and the assumed vesting of outstanding RSUs.

Diluted net income per common share attributable to stockholders for fiscal 2016, 2015, and 2014 includes 10,654,070, 18,982,440 and 15,429,003 shares, respectively, issuable upon the exchange of the Company's 2.125% junior subordinated convertible debentures due December 15, 2037 (see Note 15).  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 amountat 85% of the debenturesvalue of its common stock on specific dates. Since the inception of the employee stock purchase plans, 35,000,572 shares of common stock have been authorized for issuance and 10,929,886 shares remain available for future purchases as of March 31, 2022.

Employees purchased 1,485,477 shares of common stock in the fiscal year ended March 31, 2022 for a purchase price of $70.0 million under the employee stock purchase plans compared to 1,424,440 shares of common stock for a purchase price of $57.7 million in the fiscal year ended March 31, 2021 and 1,574,568 shares of common stock for a purchase price of $55.6 million in the fiscal year ended March 31, 2020. As of March 31, 2022, unrecognized share-based compensation costs related to the employee stock plans totaled $7.2 million, which will be settled in cash upon conversion.  Prior to conversion, the Company will include, in the diluted net income per common share calculation, the effectrecognized over a period of the additional shares that may be issued whenapproximately five months.

Note 15. Stock Repurchase Activity

In November 2021, the Company's commonBoard of Directors approved a new 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 2016, 2015 and 2014 was $24.73, $25.48 and $26.32, respectively. 

There were no shares issuable upon the exchange of the Company's 1.625% senior subordinated convertible debentures due February 15, 2025 (see Note 14). The debentures have no impact on diluted net income per common share unless the average pricerepurchase program to repurchase up to $4.00 billion of the Company's common stock exceedsin the conversion price becauseopen market or in privately negotiated transactions. There is no expiration date associated with the principal amount ofrepurchase program. During the debentures will be settled in cash upon conversion.  Prior to conversion,fiscal year ended March 31, 2022, the Company will include, in the diluted net income per common share calculation, the effectpurchased approximately 5.6 million shares of the additional shares that may be issued when the Company'sits common stock price exceedsfor a total of $425.6 million under the conversion price usingnew authorization. As of March 31, 2022, approximately $3.57 billion remained available for repurchases under the treasury stock method.  The weighted average conversion price per share used in calculating the dilutive effect of the convertible debt for fiscal 2016 and 2015 was $67.19 and $68.25, respectively.

Weighted average common shares exclude the effect of option shares which are not dilutive.  For fiscal 2016 and 2015, the number of option shares that were antidilutive was 298,015 and 19,305, respectively.program. There were no antidilutive option shares for fiscal 2014.

28.    SUBSEQUENT EVENTS
Acquisition of Atmel
On April 4, 2016, the Company acquired Atmel, a publicly traded company based in San Jose, California. The Company paid an aggregate of approximately $2.98 billion in cash and issued an aggregate of 10.1 million shares of its common stock to Atmel stockholders. The total consideration transferred in the acquisition, including approximately $6.7 million of non-cash consideration for the exchange of certain share-based payment awards of Atmel for stock awards of the Company, was approximately $3.47 billion. The Company financed the cash portion of the purchase price using approximately $2.04 billion of cash, cash equivalents, short-term investments and long-term investments held by certain of its foreign subsidiaries, and approximately $0.94 billion from additional borrowings under its existing credit agreement. As a result of the acquisition, Atmel became a wholly owned subsidiary of the Company. Atmel is a worldwide leader in the design and manufacture of microcontrollers, capacitive touch solutions, advanced logic, mixed-signal, nonvolatile memory and RF components. The Company's primary reason for this acquisition was to expand the Company's range of solutions, products and capabilities by extending its served available market.
The acquisition was accounted for under the acquisition method of accounting, with the Company identified as the acquirer, and the operating results of Atmel have been included in the Company's consolidated financial statements as of the closing date of the acquisition. Under the acquisition method of accounting, the aggregate amount of consideration paid by the Company was allocated to Atmel's net tangible assets and intangible assets based on their estimated fair values as of April 4, 2016.  The excess of the purchase price over the value of the net tangible assets and intangible assets was recorded to goodwill. The factors contributing to the recognition of goodwill were based upon the Company's conclusion that there are strategic and synergistic benefits that are expected to be realized from the acquisition. The goodwill has been allocated to the Company's semiconductor products reporting segment.  None of the goodwill related to the Atmel acquisition is deductible for tax purposes.  The Company retained an independent third-party appraiser to assist management in its valuation; however, the purchase price allocation has not been finalized. This could result in adjustments to the fair values of the assets acquired and liabilities assumed, the useful lives of intangible assets, the residual amount allocated to goodwill and deferred income taxes recognized. The preliminary allocation of the purchase price is based on the best estimates of management and is subject to revision based on the final valuations and estimates of useful lives.

The table below represents the preliminary allocation of the purchase price to the net assets acquired based on their estimated fair values, as well as the associated estimated useful lives of the acquired intangible assets (amounts in thousands). Such amounts were estimated using the most recent audited financial statements of Atmel as of December 31, 2015. The Company does not believe the allocation as of April 4, 2016 will be materially different, however, certain amounts, such as the balances of cash and cash equivalents, accounts receivable, inventories, accounts payable and other current liabilities may vary based upon changes in Atmel’s balances between December 31, 2015 and April 4, 2016, with offsetting changes to goodwill. The Company’s consolidated financial statements as of June 30, 2016 will include updated amounts reflecting the April 4, 2016 estimated fair values.

In-process technology10-15 114,500
Customer-related5 435,900
Backlog1-2 12,300
Total purchased intangible assets  $1,551,100
Purchased intangible assets include core and developed technology, in-process research and development, customer-related intangibles and acquisition-date backlog. The estimated fair values of the core and developed technology and in-process research and development were determined based on the present value of the expected cash flows to be generated by the respective existing technology or future technology. The core and developed technology intangible assets are being amortized commensurate with the expected cash flows used in the initial determination of fair value. In-process technology 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.
Customer-related intangible assets consist of Atmel's contractual relationships and customer loyalty related to its distributor and end-customer relationships, and the fair values of the customer-related intangibles were determined based on Atmel's projected revenues. An analysis of expected attrition and revenue growth for existing customers was prepared from Atmel's historical customer information.  Customer relationships are being amortized in a manner consistent with the estimated cash flows associated with the existing customers and anticipated retention rates. Backlog relates to the value of orders not yet shipped by Atmel at the acquisition date, and the preliminary fair values were based on the estimated profit associated with those orders. Backlog related assets are being recognized commensurate with recognition of the revenue for the orders on which the backlog intangible assets were determined.  Amortization expense associated with acquired intangible assets is not deductible for tax purposes.  Thus, approximately $143.2 million was established as a net deferred tax liability for the future amortization of the intangible assets.
No sales or expenses of Atmel were included in the Company’s consolidated statements of income for the year ended March 31, 2016.

The following unaudited pro-forma consolidated results of operations for the years ended March 31, 2016 and 2015 assume the Atmel acquisition occurred as of April 1, 2014. The pro-forma adjustments are mainly comprised of acquired inventory fair value costs and amortization of purchased intangible assets. The pro-forma results of operations are presented for informational purposes only and are not indicative of the results of operations that would have been achieved if the acquisition had taken place on April 1, 2014 or of results that may occur in the future (amounts in thousands except per share data):

As a result of the Company's acquisition of Atmel, the Company became involved with the following lawsuits.

In re: Continental Airbag Products Liability Litigation. On May 11, 2016, an Amended and Consolidated Class Action Complaint ("Complaint") was filed in the United States District Court for the Southern District of Florida (Miami Division) against Atmel, Continental Automotive Systems, Inc., Honda Motor Co., Ltd. and an affiliate, and Daimler AG and an affiliate. The Complaint which includes claims arising under federal law and Florida, California, New Jersey, Michigan and Louisiana state law-alleges that class members unknowingly purchased or leased vehicles containing defective airbag control units (allegedly incorporating defective application specific integrated circuits manufactured by Atmel between 2006 and 2010), and thereby suffered financial harm, including a loss in the value of their purchased or leased vehicles. The plaintiffs are seeking unspecified compensatory and exemplary damages, statutory penalties, pre- and post-judgment interest, attorneys’ fees, and injunctive and other relief. Atmel intends to contest plaintiffs' claims vigorously.

Southern District of New York Action by LFoundry Rousset ("LFR") and LFR Employees. On March 4, 2014, LFR and Jean-Yves Guerrini, individually and on behalf of a putative class of LFR employees, filed an action in the United States District Court for the Southern District of New York (the "District Court") against Atmel, its French subsidiary, Atmel Rousset S.A.S. ("Atmel Rousset"), and LFoundry GmbH ("LF"), LFR's German parent. The case purports to relate to Atmel Rousset's June 2010 sale of its wafer manufacturing facility in Rousset, France to LF, and LFR's subsequent insolvency, and later liquidation, more than three years later. The District Court dismissed the case on August 21, 2015, and plaintiffs are appealing the dismissal.

Individual Labor Actions by former LFR Employees. In the wake of LFR's insolvency and liquidation, over 500 former employees of LFR have filed individual labor actions against Atmel Rousset in a French labor court. Atmel Rousset believes that each of these actions is entirely devoid of merit, and, further, that any assertion by any of the Claimants of a co-employment relationship with Atmel Rousset is based substantially on the same specious arguments that the Paris Commercial Court summarily rejected in 2014 in related proceedings. Atmel Rousset therefore intends to defend vigorously against each of these claims.
