Company Response to COVID-19

On January 30,In March 2020, the World Health Organization (“WHO”) announced a global health emergency because of a new strain of coronavirus originating in Wuhan, China (the “COVID-19 outbreak”) and the risks to the international community as the virus spreads globally.

In March 2020, the WHO classified the outbreak of COVID-19 outbreak as a pandemic based on the rapid increase in global exposure. pandemic. Thereafter, most U.S. states imposed “shelter in place” directives on their populations to stem the spread of COVID-19. Of specific interest toCOVID-19 and similar restrictive measures were taken by governments across the Company, shelter in place directives were imposed in the states of Illinois, Massachusetts and South Carolina.world.

The shelter in place directives generally required the closure of businesses that did not provide essential functions. The Company was considered a critical supplier of products to healthcare and critical infrastructure businesses. SeveralFurther, several of our largest customers mandated that we continue to supply parts so as not to disrupt the supply chain and their ability to serve critical industries. As such, the Company qualified as an “Essential Business”.  Essential Businesses were allowed to continue to operate during shelter in place directives.  We and the Company continued our manufacturing and distribution operations even when a shelter in place directivethroughout 2021. Our top priority was issued. We limitedensuring the health and safety of our employees and, accordingly, we undertook measures such as limiting the number of people in any one of our facilities by requiring only employees who could not perform their work remotely to physically work in a Company US-based facility. The Company advised all other employees that could perform their job functions remotely to do so. As such, the Company’s operations remained operational.

The impact of the COVID-19 outbreak continuesand its effects continue to evolve. As such, the full magnitude that the pandemic, and the steps taken to prevent and/or mitigate its spread, will have on the Company’s financial condition, liquidity and future results of operations is uncertain. Management is actively monitoringThe extent of the global situationimpact of the COVID-19 pandemic depends on its financial condition, liquidity, operations, suppliers, industryfuture developments that cannot be accurately predicted at this time, such as the duration and workforce. As the spread of COVID-19 continues,the pandemic, the extent, speed and effectiveness of worldwide containment and vaccination efforts and the impact of these and other factors on our employees, customers and suppliers. Our ability to meet customer demands for products may be impaired or, similarly, our customers may experience adverse business consequences due to COVID-19.COVID-19 and its effects. Reduced demand for products or impaired ability to meet customer demand (including disruptions at our transportation service providers or vendors) could have a material adverse effect on our business, operations and financial performance. Some of theThere was a decline in fiscal 2020 PMT sales andduring the decreasefirst three months of fiscal 2021, a decline in Healthcare sales was primarily dueduring the first six months of fiscal 2021 and a decline in Canvys sales during the first nine months of fiscal 2021. The majority of these declines

in sales were related to the COVID-19 global pandemic. While we had some COVID-19 related longer lead times as well ascomponent delays impacting new product development schedules, we did not experience a major interruption in our supply chain. Management continues to monitor the global situation on its financial condition, liquidity, operations, suppliers, industry and workforce. Given the daily evolutionever-evolving nature of the COVID-19 outbreakpandemic and the continued global responses to curb its spread, the Company is not presently able to fully estimate the effects of COVID-19 on its results of operations, financial condition or liquidity for fiscal year 2021.2022.

Company Response to CARES Act

On March 27, 2020, Congress enacted the Coronavirus Aid, Relief and Economic Security (“CARES”) Act to provide certain relief as a result of the COVID-19 outbreak. The CARES Act includesincluded provisions relating to refundable payroll tax credits, deferral of employer side social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, increased limitations on qualified charitable contributions and technical corrections to tax depreciation methods for qualified, improvement property. The Company continues to examine how these provisions in the CARES Act will impact its financial position, resultsAs of operations and cash flows. In fiscal 2020,May 29, 2021, the Company deferred $0.2$0.9 million of employer sideemployer-side social security tax payments.The Company has estimated and recorded the overall effects of the CARES Act and does not anticipate a material change.

Geography

We currently have operations in the following major geographic regions: North America, Asia/Pacific, Europe and Latin America.

Selected financial data attributable to each segment and geographic region for fiscal 2021, fiscal 2020 and fiscal 2019 and fiscal 2018 is set forth in Note 11 “Segment9, Segment and Geographic Information”Information, of the notes to our consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K.

We have three operating and reportable segments, which we define as follows:

Power and Microwave Technologies Group

Power and Microwave Technologies Group (“PMT”) combines our core engineered solutions capabilities, power grid and microwave tube business with new disruptive RF, Wireless and Power disruptive technologies. As a designer, manufacturer, technology partner and authorized distributor, PMT’s strategy is to provide specialized technical expertise and engineered solutions based on our core engineering and manufacturing capabilities on a global basis. We provide solutions and add value through design-in support, systems integration, prototype design and manufacturing, testing, logistics and aftermarket technical service and repair—all through our existing global infrastructure. PMT’s focus is on products for power, RF and microwave applications for customers in 5G, alternative energy, aviation, broadcast, communications, industrial, marine, medical, military, scientific and semiconductor markets. PMT focuses on various applications including broadcast transmission, CO2 laser cutting, diagnostic imaging, dielectric and induction heating, high energy transfer, high voltage switching, plasma, power conversion, radar and radiation oncology. PMT also offers its customers technical services for both microwave and industrial equipment.

PMT represents leading manufacturers of electron tubes and RF, Microwave and power components used in semiconductor manufacturing equipment, RF and wireless and industrial power applications. Among the suppliers PMT supports are Amperex, CDE, CPI, Draloric, Eimac, General Electric, Hitachi, Jennings, L3, MACOM, National, NJRC, Ohmite, Qorvo, Thales, Toshiba and Vishay.

PMT’s inventory levels reflect our commitment to maintain an inventory of a broad range of products for customers who are buying products for replacement of components used in critical equipment and designing in new technologies. PMT also sells a number of products representing trailing edge technology. While the market for these trailing edge technology products is declining, PMT is increasing its market share. PMT often buys products it knows it can sell ahead of any supplier price increases and extended lead times. As manufacturers for these products exit the business, PMT has the option to purchase a substantial portion of their remaining inventory.

PMT has distribution agreements with many of its suppliers; most of these agreements provide exclusive distribution rights that often include global coverage. The agreements are typically long term, and usually contain provisions permitting termination by either party if there are significant breaches that are not cured within a reasonable period. Although some of these agreements allow PMT to return inventory periodically, others do not, in which case PMT may have obsolete inventory that they cannot return to the supplier.

PMT’s suppliers provide warranty coverage for the products and allow return of defective products, including those returned to PMT by its customers. For information regarding the warranty reserves, see Note 3, “SignificantSignificant Accounting Policies”Policies and Disclosures, of the notes to our consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K.

In addition to third party products, we sell proprietary products principally under certain trade names we own including Amperex®, Cetron®and National®. Our proprietary products include thyratrons and rectifiers, power tubes, ignitrons, magnetrons, phototubes, microwave generators, Ultracapacitor modules and liquid crystal display monitors. The materials used in the manufacturing process consist of glass bulbs and tubing, nickel, stainless steel and other metals, plastic and metal bases, ceramics and a wide variety of fabricated metal components. These materials are generally readily available, but some components may require long lead times for production, and some materials are subject to shortages or price fluctuations based on supply and demand.

Canvys – Visual Technology Solutions

Canvys provides customized display solutions serving the corporate enterprise, financial, healthcare, industrial and medical original equipment manufacturers markets. Our engineers design, manufacture, source and support a full spectrum of solutions to match the needs of our customers. We offer long term availability and proven custom display solutions that include touch screens, protective panels, custom enclosures, All-In-One computers, specialized cabinet finishes and application specific software packages and certification services. Our volume commitments are lower than the large display manufacturers, making us the ideal choice for companies with very specific design requirements. We partner with both private label manufacturing companies and leading branded hardware vendors to offer the highest quality display and touch solutions and customized computing platforms.

We have long-standing relationships with key component and finished goods manufacturers and several key ISO 9001 and ISO 13485 certified Asian display manufacturers that manufacture products to our specifications. We believe supplier relationships, combined with our engineering design and manufacturing capabilities and private label partnerships, allow us to maintain a well-balanced and technologically advanced offering of customer specific display solutions.

Healthcare

Healthcare manufactures, repairs, refurbishes and distributes high value replacement parts and equipment for the healthcare market including hospitals, medical centers, asset management companies, independent service organizations and multi-vendor service providers. Products include diagnostic imaging replacement parts for CT and MRI systems; replacement CT and MRI tubes; CT service training; MRI coils, cold heads and RF amplifiers; hydrogen thyratrons, klystrons, magnetrons; flat panel detector upgrades; pre-owned CT systems; and additional replacement solutions currently under development for the diagnostic imaging service market. Through a combination of newly developed products and partnerships, service offerings and training programs, we believe we can help our customers improve efficiency and deliver better clinical outcomes while lowering the cost of healthcare delivery.

Sales and Product Management

We have employees, as well as authorized representatives who are not our employees, selling our products primarily in regions where we do not have a direct sales presence.

We offer various credit terms to qualifying customers as well as cash in advance and credit card terms. We establish credit limits for each customer and routinely review delinquent and aging accounts.

Distribution

We maintain approximately 110,700 part numbers in our product inventory database and we estimate that more than 90% of orders received by 6:00 p.m. local time are shipped complete the same day for stock product. Customers can access our products on our web sites, www.rell.com, www.rellhealthcare.com, www.canvys.com, www.rellpower.com, www.relltubes.com and www.rellaser.com, through electronic data interchange, or by telephone. Customer orders are processed by our regional sales offices and supported primarily by one of our distribution facilities in LaFox, Illinois; Fort Mill, South Carolina; Amsterdam, Netherlands; Marlborough, Massachusetts; Donaueschingen, Germany; or Singapore, Singapore. We also have satellite warehouses in Sao Paulo, Brazil; Shanghai, China; Bangkok, Thailand; and Hook, United Kingdom. Our data processing network provides on-line, real-time interconnection of all sales offices and central distribution operations, 24 hours per day, seven days per week. Information on stock availability, pricing in local currency, cross-reference information, customers and market analyses are obtainable throughout the entire distribution network.

International Sales

During fiscal 2020,2021, we made approximately 59% of our sales outside the U.S. We continue to pursue new international sales to further expand our geographic reach.

Major Customers

During fiscal 2021, fiscal 2020 and fiscal 2019, no one customer accounted for more than 10 percent of the Company’s consolidated net sales. During fiscal 2018, LAM Research Corporation individually accounted for 11 percent of the Company’s consolidated net sales. No other customer accounted for more than 10 percent of the Company’s consolidated net sales in fiscal 2018. The Company believes that the loss of this customer would have a material adverse effect on the Company’s financial condition or results of operations. See Note 11 “Segment9, Segment and Geographic Information”Information, of the notes to our consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K for further information.

EmployeesHuman Capital Management

The future success of our company depends on our ability to attract, hire, motivate, retain and further develop top talent, including highly-skilled technical, management and sales personnel. The skills, experience and industry knowledge of our employees significantly benefit our operations and performance. Competition for such personnel is intense and the salary, benefits and other costs to employ the right personnel may impact our results and performance.

As of May 30, 2020,29, 2021, we employed 394405 individuals, which included 373 full-time individuals and 32 part-time individuals. Of these, 250 full-time and 18 part-time were located in the United States and 123 full-time and 14 part-time were located internationally.  All of our employees are non-union and we consider our relationships with our employees to be good.

The Company offers employees a competitive compensation program, designed to recognize and reward both individual and company performance, which includes a base pay, variable compensation programs, and health, wellbeing and retirement programs to meet the needs of our employees.

The health, safety and wellness of our employees is a priority that was a particular focus in 2021 in light of COVID-19, including having many of our employees work from home whenever possible while implementing additional safety measures for employees continuing critical on-site work.

ITEM 1A. Risk Factors

Investors should consider carefully the following risk factors in addition to the other information included and incorporated by reference in this Annual Report on Form 10-K that we believe are applicable to our businesses and the industries in which we operate. While we believe we have identified the key risk factors affecting our businesses, there may be additional risks and uncertainties that are not presently known or that are not currently believed to be significant that may adversely affect our results of operations.

A significant portion of our cash, cash equivalentsBusiness and investments are held by our foreign subsidiaries and could affect future liquidity needs.Operational Risks

As of May 30, 2020, $16.2 million, or approximately 35% of our cash, cash equivalents and investments was held by our foreign subsidiaries. While we intend to use some of the cash held outside the United States to fund our international operations and growth, when we encounter a significant need for liquidity domestically or at a particular location that we cannot fulfill through other internal or external sources, our liquidity requirements could necessitate transfers of existing cash balances between our subsidiaries or to the United States. Some of these subsidiaries are located in jurisdictions that require foreign government approval before a cash repatriation can occur.

We may not achieve our plan for sales growth and margin targets.

We have established both margin and expense targets to grow our sales with new and existing customers. If we do not achieve our growth objectives, the complexity of our global infrastructure makes it difficult to leverage our fixed cost structure to align with the size of our operations. Factors that could have a significant effect on our ability to achieve these goals include the following:

Failure

In addition, the impact of the COVID-19 pandemic resulted in sales declines across our three business units at various times during fiscal 2021. While many regions are seeing a recovery from the outbreak, the situation continues to achieve our salesevolve and margin growth objectives in our product linesthe effects of the pandemic could adversely affect the Company’s revenues, earnings, liquidity and business units;cash flows.

We have historically incurred significant charges for inventory obsolescence and may incur similar charges in the future.

We maintain significant inventories in an effort to ensure that customers have a reliable source of supply. Our products generally support industrial machinery powered by tube technology. As technology evolves and companies replace this capital equipment, the market for our products potentially declines. In addition, the market for many of our other products changes rapidly resulting from the development of new technologies, evolving industry standards, frequent new product introductions by some of our suppliers and changing end-user demand, which can contribute to the decline in value or obsolescence of our inventory. We do not have many long-term supply contracts with our customers. If we fail to anticipate the changing needs of our customers or we do not accurately forecast customer demand, our customers may not place orders with us, and we may accumulate significant inventories of products that we may be unable to sell or return to our vendors. This may result in a decline in the value of our inventory.

We face competitive pressures that could have a material adverse effect on our business.

Our overall competitive position depends on a number of factors including price, engineering capability, vendor representation, product diversity, lead times and the level of customer service. There are very few vacuum tube competitors in the markets we serve. There are also a limited number of Chinese manufacturers whose ability to produce vacuum tubes has progressed over the past several years. The most significant competitive risk comes from technical obsolescence. Canvys faces many competitors in the markets we serve. Increased competition may result in price reductions, reduced margins or a loss of market share, any of which could materially and adversely affect our business, operating results and financial condition. As we expand our business and pursue our growth initiatives, we may encounter increased competition from current and/or new competitors. Our failure to maintain and enhance our competitive position could have a material adverse effect on our business.      

A single stockholder has voting control over us.

As of July 27, 2020, Edward J. Richardson, our Chairman, Chief Executive Officer and President, beneficially owned approximately 99% of the outstanding shares of our Class B common stock, representing approximately 65% of the voting power of the outstanding common stock. This share ownership permits Mr. Richardson to exert control over the outcome of stockholder votes, including votes concerning the election of directors, by-law amendments, possible mergers, corporate control contests, and other significant corporate transactions. 

Failure to attract and retain key skilled personnel could hurt operations.

Our success depends to a large extent upon the continued services of key management personnel, particularly Mr. Richardson. While we have employment contracts in place with several of our executive officers, we nevertheless cannot be assured that we will retain our key employees and the loss of service of any of these officers or key management personnel could have a material adverse effect on our business growth and operating results.

Our future success will require an ability to attract and retain qualified employees. Competition for such key personnel is intense and we cannot be assured that we will be successful in attracting and retaining such personnel. We cannot make assurances that key personnel will not depart in the future. Changes in the cost of providing employee benefits in order to attract and retain personnel, including changes in health care costs, could lead to increased costs in any of our operations.

We are dependent on a limited number of vendors to supply us with essential products.

The products we supply are currently produced by a relatively small number of manufacturers. One of our suppliers represented 16 percent15% of our total cost of sales. Our success depends, in large part, on maintaining current vendor relationships and developing new relationships. To the extent that our significant suppliers are unwilling or unable to continue to do business with us, extend lead times, limit supplies due to capacity constraints or other factors, there could be a material adverse effect on our business.

International operations represent a significant percentage of our business and present a variety of risks that could impact our results. 

Because we source and sell our products worldwide, our business is subject to risks associated with doing business internationally. These risks include the costs and difficulties of managing foreign entities, limitations on the repatriation and investment of funds, cultural differences that affect customer preferences and business practices, unstable political or economic conditions, trade protection measures and import or export licensing requirements, and changes in tax laws.

We also face exposure to fluctuations in foreign currency exchange rates because we conduct business outside of the United States. Price increases caused by currency exchange rate fluctuations may make our products less competitive or may have an adverse effect on our margins. Our international revenues and expenses generally are derived from sales and operations in currencies other than the U.S. dollar. Accordingly, when the U.S. dollar strengthens in relationexperienced some COVID-19 related component delays impacting new product development schedules. Further disruptions to the base currenciessupply chain because of the countries in which we sell our products, our U.S. dollar reported net revenue and income would decrease. We currently do not engage in any currency hedging transactions. We cannot predict whether foreign currency exchange risks inherent in doing business in foreign countries will have a material adverse effect on our operations and financial results in the future. Further, global economic conditions may cause volatility and disruptions in the capital and credit markets. Negative or uncertain financial and macroeconomic conditions may have a significant adverse impact on our sales, profitability, and results of operations.

We may need to raise additional funds through debt or equity financings in the future to fund our domestic operations and our broader corporate initiatives, which would dilute the ownership of our existing shareholders.

If the cash generated by our domestic operations is not sufficient to fund our domestic operations and our broader corporate initiatives, such as stock repurchases, dividends, acquisitions, and other strategic opportunities, we may need to raise additional funds through public or private debt or equity financings, or we may need to obtain new credit facilities to the extent we are unable to, or choose not to, repatriate our overseas cash. Such additional financing may not be available on terms favorable to us, or at all, and any new equity financings or offerings would dilute our current stockholders’ ownership interests in us. Furthermore, lenders may not agree to extend us new, additional or continuing credit. The COVID-19 pandemic and its economic impact could result in significant or sustained disruption of global financial markets, thereby reducing our ability to access capital. In any such case, our business, operating results or financial condition could be adversely impacted.

The withdrawal by the United Kingdom from the European Union could have a material adverse effect on our business, financial position, liquidity and results of operations.

We conduct a significant portion of our business in the European Union (“EU”) and in June 2016, voters approved the withdrawal of the United Kingdom (“U.K.”) from the EU (also referred to as “Brexit”). The U.K. left the EU on January 31, 2020, and is currently in an 11-month transition period following which it will leave the single market and customs union pursuant to terms of a trade agreement currently being negotiated by the U.K. and the EU. The terms of this trade agreement are uncertain, and the political and economic instability created by Brexit caused and may continue to cause significant volatility in global markets. Further, the terms ultimately reached may result in greater restrictions on imports and exports between the U.K. and EU countries, a fluctuation in currency exchange rates and increased regulatory complexities. The impact of the withdrawal of the U.K. may adversely affect business activity, political stability and economic conditions in the U.K., the EU and elsewhere. Such developments and their ultimate impact, or the perception that any of these developments are likely to occur,other world or domestic events could have a material adverse effect on economic growth or business activity in the U.K., the Eurozone, or the EU,materially adversely impact our operations and could result in the relocation of businesses, cause business interruptions, lead to economic recession or depression, and impact the stability of the financial markets, availability of credit, political systems or financial institutions and the financial and monetary system.

Such developments could have a material adverse effect on our business, financial position, liquidity and results of operations. The uncertainty concerning the terms of the exit could also have a negative impact on the growth of the European economy and cause greater volatility in all of the global currencies that we currently use to transact business.

We rely heavily on information technology systems that, if not properly functioning, could materially adversely affect our business.

We rely on our information technology systems to process, analyze and manage data to facilitate the purchase, manufacture, and distribution of our products, as well as to receive, process, bill and ship orders on a timely basis. A significant disruption or failure in the design, operation, security or support of our information technology systems could significantly disrupt our business.

Our information technology systems may be subject to cyber attacks, security breaches or computer hacking. Experienced computer programmers and hackers may be able to penetrate our security controls and misappropriate or compromise sensitive personal, proprietary or confidential information, create system disruptions or cause shutdowns. They also may be able to develop and deploy viruses, worms and other malicious software programs that attack our systems or otherwise exploit any security vulnerabilities. Additionally, third parties may attempt to fraudulently induce employees or customers into disclosing sensitive information such as user names, passwords or other information in order to gain access to our customers’ data or our data, including our intellectual property and other confidential business information, employee information or our information technology systems. Our systems and the data stored on those systems may also be vulnerable to security incidents or security attacks, acts of vandalism or theft, coordinated attacks by activist entities, misplaced or lost data, human errors or other similar events that could negatively affect our systems and its data, as well as the data of our business partners. Further, third parties, such as hosted solution providers, that provide services to us, could also be a source of security risk in the event of a failure of their own security systems and infrastructure.

The costs to mitigate or address security threats and vulnerabilities before or after a cyber incident could be significant. Our remediation efforts may not be successful and could result in interruptions, delays or cessation of service, and loss of existing or

potential suppliers or customers. In addition, breaches of our security measures and the unauthorized dissemination of sensitive personal, proprietary or confidential information about us, our business partners or other third parties could expose us to significant potential liability and reputational harm. As threats related to cyber attacks develop and grow, we may also find it necessary to make further investments to protect our data and infrastructure, which may impact our profitability. As a global enterprise, we could also be negatively impacted by existing and proposed laws and regulations, as well as government policies and practices related to cybersecurity, privacy, data localization and data protection.

Our products may be found to be defective or our services performed may result in equipment or product damage and, as a result, warranty and/or product liability claims may be asserted against us.

We sell many of our components at prices that are significantly lower than the cost of the equipment or other goods in which they are incorporated. Since a defect or failure in a product could give rise to failures in the equipment that incorporates them, we may face claims for damages that are disproportionate to the revenues and profits we receive from the components involved in the claims. While we typically have provisions in our agreements with our suppliers that hold the supplier accountable for defective products, and we and our suppliers generally exclude consequential damages in our standard terms and conditions, our ability to avoid such liabilities may be limited as a result of various factors, including the inability to exclude such damages due to the laws of some of the countries where we do business. Our business could be adversely affected as a result of a significant quality or performance issues in the components sold by us if we are required to pay for the damages. Although we have product liability insurance, such insurance is limited in coverage and amount.

Substantial defaults by our customers on our accounts receivable or the loss of significant customers could have a significant negative impact on our business.

We extend credit to our customers. The failure of a significant customer or a significant group of customers to timely pay all amounts due could have a material adverse effect on our financial condition and results of operations. The extension of credit involves considerable judgment and is based on management’s evaluation of factors that include such things as a customer’s financial condition, payment history and the availability of collateral to secure customers’ receivables.

Failure to successfully implement our growth initiatives, or failure to realize the benefits expected from these initiatives if implemented, may create ongoing operating losses or otherwise adversely affect our business, operating results and financial condition.

Our growth strategy focuses on expanding our healthcare and our power conversion businesses. In 2015, we acquired certain assets, including inventory, receivables, fixed assets and certain other assets, of International Medical Equipment and Services, Inc. (“IMES”) and launched Power and Microwave Technologies Group (“PMT”), which combines our core engineered solutions, power grid and microwave tube business with new RF and power technologies. We may be unable to implement our growth initiatives or reach profitability in the near future or at all, due to many factors, including factors outside of our control. If our investments in these growth initiatives do not yield anticipated returns for any reason, our business, operating results and financial condition may be adversely affected.

We may not be successful in identifying, consummating and integrating future acquisitions.

As part of our growth strategy, our intent is to acquire additional businesses or assets. We may not be able to identify attractive acquisition candidates or complete the acquisition of identified candidates at favorable prices and upon advantageous terms. Also, acquisitions are accompanied by risks, such as potential exposure to unknown liabilities and the possible loss of key employees and customers of the acquired business. In addition, we may not obtain the expected benefits or cost savings from acquisitions. Acquisitions are subject to risks associated with financing the acquisition, and integrating the operations, personnel and systems of the acquired businesses. If any of these risks materialize, they may result in disruptions to our business and the diversion of management time and attention, which could increase the costs of operating our existing or acquired businesses or negate the expected benefits of the acquisitions.

Economic weakness and uncertainty could adversely affect our revenues and gross margins.

Our revenues and gross profit margins depend significantly on global economic conditions, the demand for our products and services and the financial condition of our customers. Economic weakness and uncertainty have in the past, and may in the future, result in decreased revenues and gross profit margins. Economic uncertainty also makes it more difficult for us to forecast overall supply and demand with a great deal of confidence. Financial turmoil affecting the banking system and financial markets could result in tighter credit markets and lower levels of liquidity in some financial markets. The effects of a tightened credit environment could include the insolvency of key vendors or their inability to obtain credit to finance development and/or manufacture products resulting in product delays as well as the inability of customers to obtain credit to finance operations and/or customer insolvencies. Spending

and the timing thereof by our customers may have a significant impact on our results and, where such spending is delayed or cancelled, it could have a material negative impact on our operating results. Current global economic conditions remain uncertain and challenging. Weakness in the markets in which we operate could negatively impact our revenue and operating expenses, and consequently have a material adverse effect on our business, financial condition and results of operations.

Our operating results duringproduced net income for fiscal 2021, but operating results for fiscal 2020 and fiscal 2019 reflected a net loss, while we reported net income for fiscal 2018.loss. There can be no assurance that we will experiencecontinue recovery in the near future; nor is there any assurance that such worldwide economic volatility experienced recentlyin connection with the COVID-19 pandemic, its repercussions, actions taken in response to the pandemic and attempts at recovery will not continue.

Our business and results of operations are subject to a broad range of uncertainties arising out of world and domestic events.

Our business and results of operations are subject to uncertainties arising from world and domestic events. These uncertainties may include a global economic slowdown, pandemics and other public health issues (including the COVID-19 pandemic), natural disasters, military action, terrorist activities, political and social turmoil, civil unrest and other crises. Such conditions have impacted and may continue to impact customer demand as well as our suppliers’ ability to supply us with necessary materials and, ultimately, may have an impact on our business, financial condition, results and stock price.

The COVID-19 outbreak was declared a pandemic in March 2020 based on the rapid increase in global exposure. In response, the governments of many countries, states, cities and other geographic regions (including areas in which we have operations) took preventative or protective actions, such as imposing restrictions on business operations and requiring individuals to stay at home. As the impact of the COVID-19 outbreak and responses to the pandemic continue to evolve and be felt, our ability to meet customer demand for products may be impaired or, similarly, our customers may experience adverse business consequences due to COVID-19. During fiscal 2021, the Company experienced decreases in demand for certain products as a result of the impact of COVID-19 on certain customers and in certain regions. A significant reduced demand for products or impaired ability to meet customer demand (including disruptions at our transportation service providers or vendors) could cause a material adverse effect on our business, operations and financial performance.

COVID-19 continues to spread in various regions of the world. The extent to which our business will be impacted will depend on future developments which are highly uncertain and cannot be predicted. These include but not limited to the continued duration and spread of the pandemic, its severity, the effectiveness of actions to vaccinate populations, contain the virus or treat its impact and how quickly and to what extent normal economic and operating conditions resume. The potential effects of COVID-19, the responses to the pandemic and the various recovery initiatives may also impact many of our risk factors described herein; however, as this is an unprecedented and changing situation, the potential impacts to such risk factors remain uncertain. Even after the COVID-19 pandemic subsides, we may experience adverse impacts to our business and financial results due to any economic recession or depression that has occurred, and due to any major public health crises that may occur in the future. This is a very dynamic situation and we cannot at this time reasonably estimate the scope of its impact on our employees, operations, suppliers or customers, or the full extent to which COVID-19 could continue to affect the global economy and our results.

Major disruptions to our logistics capability or to the operations of our key vendors or customers could have a material adverse impact on our operations.

We operate our global logistics services through specialized and centralized distribution centers. We depend on third party transportation service providers for the delivery of products to our customers. A major interruption or disruption in service at any of our distribution centers, or a disruption at the operations of any of our significant vendors or customers, for any reason, including reasons beyond our control (such as natural disasters, pandemics (such as the outbreak of a novel strain of coronavirus, now known as COVID-19), work stoppages, power loss, cyber attacks, incidents of terrorism or other significant disruptions of services from our third party providers) could cause cancellations or delays in a significant number of shipments to customers and, as a result, could have a severe impact on our business, operations and financial performance.

A significant portion of COVID-19 virus originated in Wuhan, China,our cash, cash equivalents and has since spreadinvestments is held by our foreign subsidiaries and could affect future liquidity needs.

As of May 29, 2021, $17.8 million, or approximately 41% of our cash and cash equivalents was held by our foreign subsidiaries. While we intend to use some of the cash held outside the United States to fund our international operations and growth, when we encounter a numbersignificant need for liquidity domestically or at a particular location that we cannot fulfill through other internal or external sources, our liquidity requirements could necessitate transfers of other countries, includingexisting cash balances between our subsidiaries or to the United States. The outbreakSome of these subsidiaries are located in jurisdictions that require foreign government approval before a cash repatriation can occur.

International operations represent a significant percentage of our business and actions takenpresent a variety of risks that could impact our results. 

Because we source and sell our products worldwide, our business is subject to risks associated with doing business internationally. These risks include the costs and difficulties of managing foreign entities, limitations on the repatriation and investment of funds, cultural differences that affect customer preferences and business practices, unstable political or economic conditions, trade protection measures and import or export licensing requirements and changes in tax laws.

We also face exposure to fluctuations in foreign currency exchange rates because we conduct business outside of the United States. Price increases caused by currency exchange rate fluctuations may make our products less competitive or may have an adverse effect on our margins. Our international revenues and expenses generally are derived from sales and operations in currencies other than the Chinese government resultedU.S. dollar. Accordingly, when the U.S. dollar strengthens in travel restrictions and extended shutdowns of certain businesses in the region. As a result, we experienced cancellations and delays in shipments to our customers in China as well as receiving shipments from our vendors in China during our third and fourth quarters of fiscal 2020. On January 30, 2020, the World Health Organization (“WHO”) announced a global health emergency and the risksrelation to the international community asbase currencies of the virus spreads globally. In March 2020, the WHO classified the COVID-19 outbreak as a pandemic, based on the rapid increase in global exposure. In response, the governments of many countries states, cities and other geographic regions (including areas in which we sell our products, our U.S. dollar reported net revenue and income would decrease. We currently do not engage in any currency hedging transactions. We cannot predict whether foreign currency exchange risks inherent in doing business in foreign countries will have operations) took preventative or protective actions, such as imposing restrictionsa material adverse effect on businessour operations and requiring individuals to stay at home.

However, there remains uncertainties and risks to our business related to Brexit and financial results duethe new relationship between the U.K. and EU, which will continue to be developed and defined, as well as any resulting political and economic instability created by Brexit. The political and economic impact of Brexit has caused and may continue to cause significant volatility in global markets as well as greater restrictions on imports and exports between the U.K. and EU countries, a fluctuation in currency exchange rates and increased regulatory complexities. The impact of the withdrawal of the U.K. may adversely affect business activity, political stability and economic conditions in the U.K., the EU and elsewhere. Such developments and their ultimate impact, or the perception that any of these developments are likely to occur, could have a material adverse effect on economic growth or business activity in the U.K., the Eurozone or the EU, and could result in the relocation of businesses, cause business interruptions, lead to economic recession or depression, that has occurred, and due to any major public health crises that may occurinhibit the growth of the European economy, cause greater volatility in the future.

Our business and results of operations are subject to uncertainties arising out of world and domestic events. These uncertainties may include a global economic slowdown, pandemics and other public health issues (including the COVID-19 pandemic), natural disasters, military action, terrorist activities, political and social turmoil, civil unrest and other crises. Such conditions may impact customer demand as well as our suppliers’ ability to supply us with necessary materials and, ultimately, may have an impactmaterial adverse effect on our business, financial position, liquidity and results of operations.

Financial Risks

We may need to raise additional funds through debt or equity financings in the future to fund our domestic operations and our broader corporate initiatives, which would dilute the ownership of our existing shareholders.

If the cash generated by our domestic operations is not sufficient to fund our domestic operations and our broader corporate initiatives, such as stock repurchases, dividends, acquisitions and other strategic opportunities, we may need to raise additional funds through public or private debt or equity financings, or we may need to obtain new credit facilities to the extent we are unable to, or choose not to, repatriate our overseas cash. Such additional financing may not be available on terms favorable to us, or at all, and any new equity financings or offerings would dilute our current stockholders’ ownership interests in us. Furthermore, lenders may not agree to extend us new, additional or continuing credit. Economic uncertainty or adverse economic conditions resulting from the impacts of and responses to the COVID-19 pandemic could result in significant or sustained disruption of global financial markets, thereby reducing our ability to access capital. In any such case, our business, operating results or financial condition resultscould be adversely impacted.

There is a possible risk of identifiable intangible asset impairment, which could reduce the value of our assets and stock price.reduce our net income in the year in which the write-off occurs.

Our intangible assets could become impaired, which could reduce the value of our assets and reduce our net income in the year in which the write-off occurs. We ascribe value to certain intangible assets which consist of customer lists and trade names resulting from acquisitions. An impairment charge on intangible assets would be incurred in the event that the fair value of the intangible assets are less than their current carrying values. We evaluate whether events have occurred that indicate all, or a portion, of the carrying amount of intangible assets may no longer be recoverable. If this is the case, an impairment charge to earnings would be necessary.

Legal and Regulatory Risks

We may be subject to intellectual property rights claims, which are costly to defend, could require payment of damages or licensing fees, and/or could limit our ability to use certain technologies in the future.

Substantial litigation and threats of litigation regarding intellectual property rights exist in the display systems and electronics industries. From time to time, third parties, including certain companies in the business of acquiring patents with the intention of aggressively seeking licensing revenue from purported infringers, have asserted and may in the future assert patent and/or other intellectual property rights to technologies that are important to our business. In any dispute involving products that we have sold, our customers could also become the target of litigation. We are obligated in many instances to indemnify and defend our customers if the products we sell are alleged to infringe any third party’s intellectual property rights. In some cases, depending on the nature of the claim, we may be able to seek indemnification from our suppliers for our self and our customers against such claims, but there is no assurance that we will be successful in obtaining such indemnification or that we are fully protected against such claims. Any infringement claim brought against us, regardless of the duration, outcome or size of damage award, could result in substantial cost, divert our management’s attention, be time consuming to defend, result in significant damage awards, cause product shipment delays, or require us to enter into royalty or other licensing agreements. See Note 12 “Risks10, Risks and Uncertainties”Uncertainties, of the notes to our consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K for further information regarding specific legal matters related to our patents.

Additionally, if an infringement claim is successful we may be required to pay damages or seek royalty or license arrangements which may not be available on commercially reasonable terms. The payment of any such damages or royalties may significantly increase our operating expenses and harm our operating results and financial condition. Also, royalty or license arrangements may not be available at all. We may have to stop selling certain products or certain technologies, which could affect our ability to compete effectively.

Potential lawsuits, with or without merit, may divert management’s attention, and we may incur significant expenses in our defense. In addition, we may be required to pay damage awards or settlements, become subject to injunctions or other equitable remedies, or determine to abandon certain lines of business, that may cause a material adverse effect on our results of operations, financial position and cash flows.

If we fail to maintain an effective system of internal controls or discover material weaknesses in our internal controls over financial reporting, we may not be able to detect fraud or report our financial results accurately or timely.

An effective internal control environment is necessary for us to produce reliable financial reports and is an important part of our effort to prevent financial fraud. We are required to periodically evaluate the effectiveness of the design and operation of our internal controls over financial reporting. Based on these evaluations, we may conclude that enhancements, modifications, or changes to internal controls are necessary or desirable. While management evaluates the effectiveness of our internal controls on a regular basis, these controls may not always be effective. There are inherent limitations on the effectiveness of internal controls, including fraud, collusion, management override, and failure in human judgment. In addition, control procedures are designed to reduce rather than eliminate business risks.

If we fail to maintain an effective system of internal controls, or if management or our independent registered public accounting firm discovers material weaknesses in our internal controls, we may be unable to produce reliable financial reports or prevent fraud. In addition, we may be subject to sanctions or investigation by regulatory authorities, such as the Securities and Exchange Commission or NASDAQ. Any such actions could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements.

If we are deemed to be an investment company, we will be required to meet burdensome compliance requirements and restrictions on our activities.

We currently have significant cash and investments. If we are deemed to be an “investment company” as defined under the Investment Company Act of 1940 (the “Investment Company Act”), the nature of our investments may be subject to various restrictions. We do not believe that our principal activities subject us to the Investment Company Act. If we are deemed to be subject to the Investment Company Act, compliance with required additional regulatory burdens would increase our operating expenses.

The company recorded a non-cash impairment charge for the full value of our goodwill and there remains the risk of possible additional future identifiable intangible asset impairment, which could reduce the value of our assets and reduce our net income in the year in which the write-off occurs.

In the fourth quarter of fiscal 2019, the Company recorded a non-cash goodwill impairment charge of $6.3 million for the full amount of the goodwill associated with the IMES reporting unit. The impairment resulted from fourth quarter events that decreased the forecasted future cash flows and the fair value of the IMES reporting unit below its carrying value as of the March 3, 2019 testing date. Refer to Note 7 “Goodwill and Intangible Assets” of the notes to our consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K.  Our remaining intangible assets could become impaired, which could reduce the value of our assets and reduce our net income in the year in which the write-off occurs. We ascribe value to certain intangible assets, which consist of customer lists and trade names resulting from acquisitions. An impairment charge on intangible assets would be incurred in the event that the fair value of the intangible assets are less than their current carrying values. We evaluate whether events have occurred that indicate all, or a portion, of the carrying amount of intangible assets may no longer be recoverable. If this is the case, an impairment charge to earnings would be necessary.

We may incur substantial operational costs or be required to change our business practices to comply with data privacy and data protection laws and regulations around the General Data Protection Regulationworld.

We are subject to many privacy and similar regulations.

data protection laws and regulations in various jurisdictions, which continue to evolve rapidly. The EU adopted theEU’s General Data Protection Regulation (“GDPR”) which went into effect in May 2018. The GDPR includes operational requirements for companies that receive or process personal data of residents of the European Union, including more robust documentation requirements for data protection compliance programs. Specifically, the GDPR introducedimposes numerous privacy-related changesrequirements for companies operating in the EU, including greater control for data subjects, increased data portability for EU consumers and data breach notification requirements.

Complying with the GDPR may cause us to incur substantial operational costs or require us to change our business practices in ways that we cannot currently predict. Despite our efforts to bring our practices into compliance with the GDPR, we may not be successful. Non-compliance could result in proceedings against us by governmental entities, customers, data subjects or others. Fines of up to 20 million euros or up to 4% of the annual global revenue of the noncompliant company, whichever is greater, may be imposed for violations of certain of the GDPR’s requirements.

In addition, several other jurisdictions in the U.S. and around the world have recently enacted privacy laws or regulations similar to GDPR. For instance, California enacted the California Consumer Privacy Act (“CCPA”), which was effective January 1, 2020 and which gives consumers many of the same rights as those available under GDPR. Several laws similar to the CCPA have been proposed in the United States at both the federal and state level. The effects of, and costs incurred in connection with complying with, the GDPR, the CCPA and other data privacy laws and regulations may be significant and may require us to modify our data processing practices and policies and to incur substantial costs and expenses in an effort to comply. Any actual or perceived failures to comply with the GDPR, the CCPA or other data privacy laws or regulations, or related contractual or other obligations, or any perceived privacy rights violation, could lead to investigations, claims and proceedings by governmental entities and private parties, damages for contract breach, and other significant costs, penalties and other liabilities, as well as harm to our reputation and market position.

Our international sales and operations are subject to applicable laws relating to trade, export controls and foreign corrupt practices, the violation of which could adversely affect our operations.

We are subject to applicable export control laws and regulations of the United States and other countries. United States laws and regulations applicable to us include the Arms Export Control Act, the International Traffic in Arms Regulations (“ITAR”), the Export Administration Regulations (“EAR”) and the trade and trade sanctions laws and regulations administered by the Office of the United States Trade Representative and the United States Department of the Treasury’s Office of Foreign Assets Control. The import and export of our products are subject to international trade agreements, the modification or repeal of which could impact our business. The U.S. government agencies responsible for administering EAR and ITAR have significant discretion in the interpretation and enforcement of these regulations. Violations of these laws or regulations could result in significant additional sanctions including fines, more onerous compliance requirements, more extensive debarments from export privileges, loss of authorizations needed to conduct aspects of our international business and criminal penalties and may harm our ability to enter contracts with customers who have contracts with the U.S. government. A violation of the laws or the regulations enumerated above could materially adversely affect our business, financial condition and results of operations.

NewOngoing changes to tariffs and the evolving trade policy dispute between the United States and Chinarelations may adversely affect our business.

Our international operations are subject to changing tariffs and developments in trade relations. The U.S. government has made statements and taken certain actions that have led to, and may in the future lead to, further changes to U.S. and international trade policies, including recently imposed tariffs affecting certain products exported by a number of U.S. trading

partners, including China. There remains uncertainty regarding tax and trade policies, border adjustments, tariffs and government regulations affecting trade between the U.S. and other countries.

For example, during 2018, the U.S. and China each imposed new tariffs, and announced further proposed tariffs, on various products imported from China and the U.S., respectively. Between July 2018 and September 2018, the Office of the United States Trade Representative imposed tariffs of 10% and 25% on three product lists totaling approximately $250 billion in Chinese imports.    These lists include some of our products. The U.S. government has also indicated a readiness to further expand the scope of the tariffs on Chinese goods and, inIn May 2019, there was an announcement of the United States government’s imposition of a 25% tariff on a range of products exported from China to the U.S. on or after May 10, 2019. China thereafter announced a plan to impose tariffs on imports to China2019. These lists include some of a wide range of American products,our products.

Subsequently, in retaliation for the American tariffs. In January 2020, China and the U.S. entered the first phase of an economic and trade agreement. There is no assurance that a broader trade agreement will be successfully negotiated between the U.S. and China signed a “phase one” trade deal, accompanied by a U.S. decision to cancel a plan to increase tariffs on an additional list of Chinese products and to reduce or eliminate existingthe tariffs applicableimposed on May 13, 2019 from 15% to 7.5% effective February 14, 2020. Currently, the businessmajority of tariff exclusions granted have expired and many of the Company.

Furthermore, the current U.S. administration may impose additional tariffs on imports from China and there is also a concern thatChinese origin goods remain, as do concerns over the impositionstability of additional tariffs bybilateral trade relations, particularly given the United States could result inlimited scope of the adoption of tariffs by other countries as well. phase one agreement.

It is possible that further tariffs may be imposed on imports of our products, including by other countries, or that our business will be impacted by retaliatorychanging trade measures taken by China or other countries in response to existing or future tariffs, causingrelations among countries. This may cause us to raise prices or make changes to our operations, any of which could adversely impact demand for our products, our costs, customers, suppliers and/or the United States economy or certain sectors thereof and, thus, to adversely impact our businesses and results of operations.

Given the uncertainty regarding the scope and durationevolving nature of the effective and proposed tariffs, as well as the potential for additional trade actions by the U.S. or other countries,relations, the impact on our operations and results is uncertain and could be significant. We can provide no assurance that any strategies we implement to mitigate the impact of such tariffs or other trade actions will be successful. To the extent that our supply chain, costs, sales or profitability are negatively affected by the tariffs or other trade actions, our business, financial condition and results of operations may be materially adversely affected.

Ownership Risks

A single stockholder has voting control over us.

As of July 26, 2021, Edward J. Richardson, our Chairman, Chief Executive Officer and President, beneficially owned approximately 98% of the outstanding shares of our Class B common stock, representing approximately 64% of the voting power of the outstanding common stock. This share ownership permits Mr. Richardson to exert control over the outcome of stockholder votes, including votes concerning the election of directors, by-law amendments, possible mergers, corporate control contests and other significant corporate transactions. 

General Risk Factors

Failure to attract and retain key skilled personnel could hurt operations.

Our success depends to a large extent upon the continued services of key management personnel, particularly Mr. Richardson. While we have employment contracts in place with several of our executive officers, we nevertheless cannot be assured that we will retain our key employees and the loss of service of any of these officers or key management personnel could have a material adverse effect on our business growth and operating results.

Our future success will require an ability to attract and retain qualified employees. Competition for such key personnel is intense and we cannot be assured that we will be successful in attracting and retaining such personnel. We cannot make assurances that key personnel will not depart in the future. Changes in the cost of providing employee benefits in order to attract and retain personnel, including changes in health care costs, could lead to increased costs in any of our operations.

If we fail to maintain an effective system of internal controls or discover material weaknesses in our internal controls over financial reporting, we may not be able to detect fraud or report our financial results accurately or timely.

An effective internal control environment is necessary for us to produce reliable financial reports and is an important part of our effort to prevent financial fraud. We are required to periodically evaluate the effectiveness of the design and operation of our internal controls over financial reporting. Based on these evaluations, we may conclude that enhancements, modifications or changes to internal controls are necessary or desirable. While management evaluates the effectiveness of our internal controls on a regular basis, these controls may not always be effective. There are inherent limitations on the effectiveness of internal controls, including fraud, collusion, management override and failure in human judgment. In addition, control procedures are designed to reduce rather than eliminate business risks.

If we fail to maintain an effective system of internal controls, or if management or our independent registered public accounting firm discovers material weaknesses in our internal controls, we may be unable to produce reliable financial reports or prevent fraud. In addition, we may be subject to sanctions or investigation by regulatory authorities, such as the Securities and Exchange Commission or NASDAQ. Any such actions could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements.

If we are deemed to be an investment company, we will be required to meet burdensome compliance requirements and restrictions on our activities.

We have had significant cash and investments. If we are deemed to be an “investment company” as defined under the Investment Company Act of 1940 (the “Investment Company Act”), the nature of our investments may be subject to various restrictions. We do not believe that our principal activities subject us to the Investment Company Act. If we are deemed to be subject to the Investment Company Act, compliance with required additional regulatory burdens would increase our operating expenses.

Evolving expectations around corporate responsibility practices, specifically related to environmental, social and governance (“ESG”) matters, may expose us to reputational and other risks.

Investors, stockholders, customers, suppliers and other third parties are increasingly focusing on ESG and corporate social responsibility endeavors and reporting. Certain institutional investors, investment funds, other influential investors, customers, suppliers and other third parties are also increasingly focused on ESG practices. Companies that do not adapt to or comply with the evolving investor or stakeholder expectations and standards, or which are perceived to have not responded appropriately, may suffer from reputational damage and result in the business, financial condition and/or stock price of a company being materially and

adversely affected. Further, this increased focus on ESG issues may result in new regulations and/or third party requirements that could adversely impact our business, or certain shareholders reducing or eliminating their holdings of our stock. Additionally, an allegation or perception that the Company has not taken sufficient action in these areas could negatively harm our reputation.

Our stock price may be volatile.

Our stock price has fluctuated in the past and may experience declines in the future as a result of the volatile nature of the stock market, developments in our business and/or factors outside of our control. Many factors may cause the market price for our common stock to change, including: (i) our operating results as compared to investors’ expectations in any period, (ii) market perceptions concerning our future earnings prospects, (iii) adverse changes in general market conditions or economic trends and (iv) changes or events in our industry or the world, such as market reactions to the COVID-19 pandemic.

Business Overview

Richardson Electronics, Ltd. is a leading global provider of engineered solutions, power grid and microwave tubes and related consumables; power conversion and RF and microwave components; high value flat panel detector solutions, replacement parts, tubes and service training for diagnostic imaging equipment; and customized display solutions. We serve customers in the alternative energy, healthcare, aviation, broadcast, communications, industrial, marine, medical, military, scientific and semiconductor markets. The Company’s strategy is to provide specialized technical expertise and “engineered solutions” based on our core engineering and manufacturing capabilities. The Company provides solutions and adds value through design-in support, systems integration, prototype design and manufacturing, testing, logistics and aftermarket technical service and repair through its global infrastructure.

Some of the Company's products are manufactured in China and are imported into the United States. The Office of the United States Trade Representative ("USTR") instituted additional 10% to 25% tariffs on the importation of a number of products into the United States from China effective July 6, 2018, with additional products added August 23, 2018 and September 24, 2018. These additional tariffs are a response to what the USTR considers to be certain unfair trade practices by China. A number of the Company's products manufactured in China are now subject to these additional duties of 25% when imported into the United States.

Management is currently workingcontinues to work with its suppliers as well as its customers to help outline and, where possible, mitigate the impact of the new tariffs on our customers’ markets. However, if the Company is unable to successfully pass through the additional cost of these tariffs, or if the higher prices reduce demand for the Company's products, it will have a negative effect on the Company's sales and gross margins.

We have three operating and reportable segments, which we define as follows:

Power and Microwave Technologies Group (“PMT”) combines our core engineered solutions capabilities, power grid and microwave tube business with new disruptive RF, Wireless and Power disruptive technologies. As a designer, manufacturer, technology partner and authorized distributor, PMT’s strategy is to provide specialized technical expertise and engineered solutions based on our core engineering and manufacturing capabilities on a global basis. We provide solutions and add value through design-in support, systems integration, prototype design and manufacturing, testing, logistics and aftermarket technical service and repair—all through our existing global infrastructure. PMT’s focus is on products for power, RF and microwave applications for customers in 5G, alternative energy, aviation, broadcast, communications, industrial, marine, medical, military, scientific and semiconductor markets. PMT focuses on various applications including broadcast transmission, CO2 laser cutting, diagnostic imaging, dielectric and induction heating, high energy transfer, high voltage switching, plasma, power conversion, radar and radiation oncology. PMT also offers its customers technical services for both microwave and industrial equipment.

Canvys provides customized display solutions serving the corporate enterprise, financial, healthcare, industrial and medical original equipment manufacturers markets. Our engineers design, manufacture, source and support a full spectrum of solutions to match the needs of our customers. We offer long term availability and proven custom display solutions that include touch screens, protective panels, custom enclosures, All-In-One computers, specialized cabinet finishes and application specific software packages and certification services. Our volume commitments are lower than the large display manufacturers, making us the ideal choice for companies with very specific design requirements. We partner with both private label manufacturing companies and leading branded hardware vendors to offer the highest quality display and touch solutions and customized computing platforms.

Healthcare manufactures, repairs, refurbishes and distributes high value replacement parts and equipment for the healthcare market including hospitals, medical centers, asset management companies, independent service organizations and multi-vendor service providers. Products include diagnostic imaging replacement parts for CT and MRI systems; replacement CT and MRI tubes; CT service training; MRI coils, cold heads and RF amplifiers; hydrogen thyratrons, klystrons, magnetrons; flat panel detector upgrades; pre-owned CT systems; and additional replacement solutions currently under development for the diagnostic imaging service market. Through a combination of newly developed products and partnerships, service offerings and training programs, we believe we can help our customers improve efficiency and deliver better clinical outcomes while lowering the cost of healthcare delivery.

We currently have operations in the following major geographic regions: North America, Asia/Pacific, Europe and Latin America.

Selling, General and Administrative Expenses

Selling, general and administrative expenses (“SG&A”) increased during fiscal 2021 to $55.9 million from $51.3 million during fiscal 2020. This increase included the $1.6 million legal settlement which is discussed in the following section. In addition to the $1.6 million legal settlement, SG&A expenses increased due to higher employee compensation expenses and higher legal fees, partially offset by lower travel and consulting expenses. SG&A as a percentage of sales decreased to 31.6% during fiscal 2021 as compared to 32.9% during fiscal 2020.

Selling, general and administrative expenses (“SG&A”) decreased during fiscal 2020 to $51.3 million from $52.2 million during fiscal 2019. SG&A as a percentage of sales increased to 32.9% during fiscal 2020 as compared to 31.3% during fiscal 2019. The decrease in expense was primarily due to lower travel, severance, legal and IT expenses, partially offset by higher employee compensation expenses.

Selling,Legal Settlement

On October 15, 2018, Varex Imaging Corporation (“Varex”) filed its original Complaint (Case No. 1:18-cv-06911) against Richardson Electronics, Ltd. (“Richardson”) in the Northern District of Illinois, which was subsequently amended on November 27, 2018. Varex alleged counts of infringement of U.S. Patent Nos. 6,456,692 and 6,519,317. Subsequently, on October 24, 2018, Varexfiled a motion for preliminary injunction to stop the sale of Richardson’s ALTA750^TM product. Richardson filed an opposition to the preliminary injunction. In January 2019, the Court took evidence on the preliminary injunction issue. On September 30, 2019, the Court denied Varex’s Motion for Preliminary Injunction. On August 6, 2020, Varex amended its Complaint to add claims of trade secret misappropriation and Richardson moved to dismiss that Amended Complaint on September 9, 2020. On April 2, 2021,as part of an overall settlement where Richardson did not admit liability but wanted to move forward, Richardson agreed to pay Varex $1.6 million to settle this matter, which was recorded in selling, general and administrative expenses (“SG&A”) increased during fiscal 2019 to $52.2 million from $51.7 million during fiscal 2018. SG&A as a percentagewithin the Consolidated Statements of sales decreased to 31.3% during fiscal 2019 as compared to 31.7% during fiscal 2018. The increase in expense was due to higher legal and severance expense related to two lawsuits litigated during fiscal 2019 and headcount reductions throughout fiscal 2019. Bad debt expense was also higher in fiscal 2019 compared to fiscal 2018 due to a large recovery that was collected in fiscal 2018. These increases were mostly offset by lower incentive expenses.

Impairment of Goodwill

In connection with a year-end impairment review of goodwill, the Company recorded a $6.3 million non-cash goodwill impairment charge in the fourth quarter of fiscal 2019 to write off all the goodwill associated with the IMES acquisition. Refer to Note 7 “Goodwill and Intangible Assets” of the notes to our consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K.Comprehensive Income (Loss).

Other Income/Expense

Other income/expense was an expense of $0.6 million during fiscal 2021, compared to income of $0.4 million during fiscal 2020,2020. Fiscal 2021 had $0.1 million of investment income compared to income of $0.5 million during fiscal 2019. Fiscal 2020 had $0.4 million of investment income. Fiscal 2019 included $0.5 million of investment income partially offset by less than $0.1 million of foreign exchange losses.for fiscal 2020. Our foreign exchange gains and losses are primarily due to the translation of U.S. dollars held in non-U.S. entities. The foreign exchange loss reported for fiscal 2021 totaled $0.8 million, compared to a slight gain for fiscal 2020. We currently do not utilize derivative instruments to manage our exposure to foreign currency.

Income Tax Provision

Our income tax provision from continuing operations during fiscal 2021, fiscal 2020 and fiscal 2019 and fiscal 2018 was $0.7 million, $0.6 million $1.0 million and $1.5$1.0 million, respectively. The effective income tax rates from continuing operations during fiscal 2021, fiscal 2020 and fiscal 2019 and fiscal 2018 were (51.4)%28.3%, (16.1)(51.4)% and 39.7%(16.1)%, respectively. The difference between the effective income tax rates as compared to the U.S. federal statutory rate of 21.0% during fiscal 2021, fiscal 2020 21.0% duringand fiscal 2019 and 29.2% during fiscal 2018 was primarily driven by the impact of recording a valuation allowance against all of our U.S. state and federal net deferred tax assets and changes in our geographical distribution of income (loss).

On December 22, 2017, the U.S. government enacted new tax legislation, Tax Cuts and Jobs Act (the “Act”). The primary provision of the Act that impacted the Company in fiscal 2019 was a reduction to the U.S. corporate income tax rate from 35% to 21%. The 21% corporate income tax rate was effective January 1, 2018 and is in effect for the Company’s full fiscal 2020 and fiscal 2019 tax years.

The Company is subject to additional requirements of the Act beginning in fiscal 2019. Those provisionsProvisions include an income inclusion for global intangible low-taxed income (“GILTI”), a tax determined by base erosion and anti-avoidance tax (“BEAT”) related to certain payments between a U.S. corporation and foreign related entities, a limitation of certain executive compensation and a deduction for foreign derived intangible income. The Company has determined its accounting policy to treat the taxes due on GILTI as a period cost. The Company is not subject to the BEAT provision due to the revenue thresholds. During fiscal 2021, final regulations were released that provide taxpayers with a high tax exception (“HTE”) election. Given the Company’s tax profile, the Company intends to make such election with its fiscal 2021 tax return, and the forecasted GILTI inclusion has been estimated assuming the HTE is elected. The Company made this election on its fiscal 2020 tax return, adjusting its NOL and offsetting valuation allowance.

As of May 30, 2020,29, 2021, we had approximately $3.7$3.0 million of net deferred tax assets related to federal net operating loss (“NOL”) carryforwards, compared to $3.1$3.7 million as of June 1, 2019.May 30, 2020. Net deferred tax assets related to domestic state NOL carryforwards at May 30, 202029, 2021 amounted to approximately $3.8$3.9 million, compared to $3.9$3.8 million at June 1, 2019.May 30, 2020. Net deferred tax assets related to foreign NOL carryforwards as of May 30, 202029, 2021 totaled approximately $0.3$0.4 million with various or indefinite expiration dates. The amount of net deferred tax assets related to foreign NOL carryforwards was $0.4$0.3 million as of June 1, 2019.May 30, 2020. We also had a domestic net deferred tax asset of $1.8 million of foreign tax credit carryforwards as of both May 29, 2021 and May 30, 2020, compared to $1.8 million as of June 1, 2019.2020. We did not have any alternative minimum tax credit carryforward as of May 30, 2020.29, 2021.

We have historically determined that undistributed earnings of our foreign subsidiaries, to the extent of cash available, will be repatriated to the U.S. The deferred tax liability on the outside basis difference is now primarily withholding tax on future dividend distributions. Accordingly, we have reduced theThe deferred tax liability related to undistributed earnings of our foreign subsidiaries from $0.2 million in fiscal 2019 towas less than $0.1 million in both fiscal 2021 and fiscal 2020.

Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. A significant component of objective evidence evaluated was the cumulative income or loss incurred in each jurisdiction over the three-year period ended May 30, 2020.29, 2021. Such objective evidence limits the ability to consider subjective evidence such as future income projections. We considered other positive evidence in determining the need for a valuation allowance in the U.S. including the subpart F and GILTI inclusions of our foreign earnings. The weight of this positive evidence is not sufficient to outweigh other negative evidence in evaluating our need for a valuation allowance in the U.S. jurisdiction.

As of May 30, 2020,29, 2021, a valuation allowance of $12.3$12.2 million was established to record only the portion of the deferred tax asset that will more likely than not be realized. The valuation allowance as of June 1, 2019May 30, 2020 was $11.7$12.3 million. We recorded a valuation allowance for all domestic federal and state net deferred tax assets considering the significant cumulative losses in the U.S. jurisdiction and the reversal of the deferred tax liability for foreign earnings and no forecast of additional U.S. income.earnings. The valuation allowance also related to deferred tax assets in foreign jurisdictions where historical taxable losses have been incurred. The amount of the deferred tax asset considered realizable, however, could be adjusted if estimates of future taxable income during the carryforward period are increased, or if objective negative evidence in the form of cumulative losses is no longer present and additional weight may be given to subjective evidence such as our projections for growth.

Income taxes paid, including foreign estimated tax payments, were $0.1 million, $1.0 million $0.3 million and $0.5$0.3 million, during fiscal 2021, fiscal 2020 and fiscal 2019, and fiscal 2018, respectively.

In the normal course of business, we are subject to examination by taxing authorities throughout the world. Generally, years prior to fiscal 2015 are closed for examination under the statute of limitation for U.S. federal, U.S. state and local or non-U.S. tax jurisdictions. We are currently under examination in Thailand (fiscal 2008 through 2011) and Germany (fiscal 2015 through 2018). Our primary foreign tax jurisdictions are Germany and the Netherlands. We have tax years open in Germany beginning in fiscal 20152019 and the Netherlands beginning in fiscal 2018.

The uncertain tax positions from continuing operations as of both May 29, 2021 and May 30, 2020 and June 1, 2019 were $0.1 million. We record penalties and interest related to uncertain tax positions in the income tax expense line item within the Consolidated Statements of Comprehensive Income (Loss) Income.. Accrued interest and penalties arewere included within the related tax liability line in the Consolidated Balance Sheets. We have not recorded a liability for interest and penalties as of May 29, 2021 or May 30, 2020 or June 1, 2019.2020. It is not expected that there will be a change in the unrecognized tax benefits due to the expiration of various statutes of limitations within the next 12twelve months.

Liquidity, Financial Position and Capital Resources

Our operations and cash needs have been primarily financed through income from operations and cash on handhand.

Cash and investments.cash equivalents were $43.3 million at May 29, 2021. Cash and cash equivalents at May 29, 2021 consisted of $26.1 million in North America, $8.8 million in Europe, $1.2 million in Latin America and $7.2 million in Asia/Pacific. We repatriated a total of $0.9 million to the United States in fiscal 2021 from several of our foreign entities. This amount includes $0.7 million from our entities in Italy and South Korea in the third quarter of fiscal 2021 and $0.2 million from our entity in France in the fourth quarter of fiscal 2021. Although the Tax Cuts and Jobs Act generally eliminated federal income tax on future cash repatriation to the United States, cash repatriation may be subject to state and local taxes, withholding or similar taxes. See Note 7, Income Taxes, of the notes to our consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K for further information.

Cash, cash equivalents and investments were $46.5 million at May 30, 2020. Cash, cash equivalents and investments at May 30, 2020, consisted of $30.6 million in North America, $8.3 million in Europe, $0.9 million in Latin America and $6.7 million in Asia/Pacific. We repatriated a total of $8.5 million to the United States in fiscal 2020 from several of our foreign entities. This amount includes $4.4 million from our entities in Germany and the Netherlands in the second quarter of fiscal 2020, $1.5 million from our entity in Japan in the third quarter of fiscal 2020 and $1.0 million from our entity in Italy in the fourth quarter of fiscal 2020. Although the Tax Cuts and Jobs Act generally eliminated federal income tax on future cash repatriation to the United States, cash repatriation may be subject to state and local taxes, withholding or similar taxes. See Note 9 “Income Taxes” of the notes to our consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K for further information.

Cash, cash equivalents and investments were $50.0 million at June 1, 2019. Cash, cash equivalents and investments at June 1, 2019, consisted of $21.5 million in North America, $17.8 million in Europe, $0.9 million in Latin America and $9.8 million in Asia/Pacific. We repatriated $2.3 million total cash from our entities in Japan and Korea in fiscal 2019 and $5.9 million total cash from our entities in Germany and France in fiscal 2019.

The Company continues to monitor the impact of COVID-19, including the COVID-19 outbreakextent, duration and effectiveness of containment actions taken, the speed and extent of vaccination programs, the impact of the pandemic on its supply chain, manufacturing and distribution operations, customers and employees, as well as the U.S. economy in general. However, due to the uncertainty as to when governmental restrictions on business will be fully lifted, the impact thereof,uncertain and the duration and widespread natureconstantly evolving impacts of the COVID-19 outbreak,pandemic across the globe, the Company cannot currently predict the long-term impact on its operations and financial results. The uncertainties associated with the COVID-19 outbreakpandemic and its effects include potential adverse effects on the overall economy, the Company’s supply chain, transportation services, employees and customers. The COVID-19 outbreakpandemic and its effects could adversely affect the Company’s revenues, earnings, liquidity and cash flows and may require significant actions in response, including expense reductions. Conditions surrounding COVID-19 change rapidly and additional impacts of which the Company is not currently aware may arise. Based on past performance and current expectations, we believe that the existing sources of liquidity, including current cash, will provide sufficient resources to meet known capital requirements and working capital needs through the next twelve months.

Cash Flows from Operating Activities

Cash flow from operating activities primarily resulted from our net lossincome adjusted for non-cash items and changes in our operating assets and liabilities.

Operating activities provided $0.8 million of cash during fiscal 2021. We had net income of $1.7 million during fiscal 2021, which included non-cash stock-based compensation expense of $0.7 million associated with the issuance of stock option awards and restricted stock awards, $1.0 million of inventory provisions and depreciation and amortization expense of $3.4 million associated with our property and equipment as well as amortization of our intangible assets.Changes in our operating assets and liabilities resulted in a use of cash of $6.0 million during fiscal 2021, primarily due to the increase in inventories of $4.9 million, an increase in accounts receivable of $4.2 million and a decrease in accounts payable of $0.6 million. These uses of cash were partially offset by the increase in our accrued liabilities of $3.6 million and the decrease in prepaid expenses and other assets of $0.1 million. The majority of the inventory increase was to support our electron tube and PMG businesses. The increase in accounts receivable was primarily due to the sales increase in fiscal 2021. The decrease in our accounts payable was due to timing of payments for some of our larger vendors for both inventory and services and the increase in accrued liabilities was due to the timing of employee compensation and payroll tax payments, as well as increased deferred revenue.

Operating activities provided $1.9 million of cash during fiscal 2020. We had net loss of $1.8 million during fiscal 2020, which included non-cash stock-based compensation expense of $0.7 million associated with the issuance of stock option awards and restricted stock awards, $1.0 million of inventory provisions and depreciation and amortization expense of $3.4 million associated with our property and equipment as well as amortization of our intangible assets.Changes in our operating assets and liabilities resulted in a use of cash of $1.3 million during fiscal 2020, primarily due to the increase in inventories of $5.5 million and the decrease in accrued liabilities of $0.9 million. These uses of cash were partially offset by the decrease in accounts receivable of $3.9 million, the increase in our accounts payable of $0.6 million and the decrease in prepaid expenses and other assets of $0.6 million. The majority of the inventory increase was to support our electron tube and Canvys businesses and the impact of COVID-19 on sales. The decrease in accounts receivable was primarily due to the decrease in sales and better collection of receivables. The increase in our accounts payable was due to timing of payments for some of our larger vendors for both inventory and services.

Operating activities used $2.6 million of cash during fiscal 2019. We had net loss of $7.3 million during fiscal 2019, which included non-cash stock-based compensation expense of $0.7 million associated with the issuance of stock option awards and restricted stock awards, $1.1 million of inventory provisions and depreciation and amortization expense of $3.2 million associated with our property and equipment as well as amortization of our intangible assets. The Company recorded a non-cash goodwill impairment charge of $6.3 million for the full amount of the goodwill associated with the IMES reporting unit. Changes in our operating assets and liabilities resulted in a use of cash of $6.8 million during fiscal 2019, primarily due to the increase in inventories of $4.2 million, the increase in accounts receivable of $2.0 million and the decrease in our accounts payable of $2.4 million. These uses of cash were partially offset by the decrease in prepaid expenses and other assets of $0.6 million and the increase in accrued liabilities of $1.1 million. The inventory increase was due to the ongoing growth of our RF and power technologies business and growth in CT Tube and component inventory as we prepare for expected ALTA750 ^TM  tube sales growth in the Healthcare market. The increase in accounts receivable was primarily due to the increase in sales. The decrease in our accounts payable was due to timing of payments for some of our larger vendors for both inventory and services. The increase in accrued liabilities was primarily due to an increase in deferred revenues as well as several accrued expenses.

Cash Flows from Investing Activities

The cash flow from investing activities consisted primarily of purchases and maturities of investments and capital expenditures.

Cash provided by investing activities of $13.4 million during fiscal 2021 included the proceeds from the maturities of investments of $25.0 million, partially offset by purchases of investments of $9.0 million and $2.6 million in capital expenditures. Capital expenditures related primarily to capital used for our IT system and Healthcare manufacturing business.

Cash used in investing activities of $9.8 million during fiscal 2020 included purchases of investments of $29.0 million and $1.8 million in capital expenditures, partially offset by the proceeds from the maturities of investments of $21.0 million. Capital expenditures related primarily to capital used for our IT system, and Healthcare and LaFox manufacturing businesses.

Cash used in investing activities of $11.9 million during fiscal 2019 included purchases of investments of $17.8 million and $3.9 million in capital expenditures, partially offset by the proceeds from the maturities of investments of $9.8 million. Capital expenditures relates primarily to our Healthcare growth initiative, a new air conditioner unit for the global headquarters, investments in our LaFox manufacturing operation and capital used for our IT system.

Our purchases and proceeds from investments consist of time deposits and CDs. Purchasing of future investments may vary from period to period due to interest and foreign currency exchange rates.

Cash Flows from Financing Activities

The cash flow from financing activities primarily consists of cash dividends paid.

Cash used in financing activities of $3.2$3.0 million during fiscal 20202021 resulted primarily from cash used to pay dividends, partially offset by proceeds from the issuance of common stock from stock option exercises.

Cash used in financing activities of $2.8$3.2 million during fiscal 20192020 resulted primarily from cash used to pay dividends, partially offset by proceeds from the issuance of common stock from stock option exercises.

All future payments of dividends are at the discretion of the Board of Directors. Dividend payments will depend on earnings, capital requirements, operating conditions and such other factors that the Board may deem relevant.

Contractual Obligations

Contractual obligations are presented in the table below as of May 30, 202029, 2021 (in thousands):

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with United States Generally Accepted Accounting Principles (“GAAP”) requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management continuously evaluates its critical accounting policies and estimates, including the allowance for doubtful accounts, revenue recognition, inventory obsolescence, goodwill and other intangible assets, loss contingencies and income taxes. Management bases the estimates on historical experience and on various other assumptions believed to be reasonable under the circumstances, however, actual results could differ from those estimates.

The policies discussed below are considered by management to be critical to understanding our financial position and the results of operations. Their application involves significant judgments and estimates in preparation of our consolidated financial statements. For all of these policies, management cautions that future events rarely develop exactly as forecasted, and the best estimates routinely require adjustment.

Allowance for Doubtful Accounts

Our allowance for doubtful accounts includes estimated losses that result from uncollectible receivables. The estimates are influenced by the following: continuing credit evaluation of customers’ financial conditions; aging of receivables, individually and in the aggregate; a large number of customers which are widely dispersed across geographic areas; and collectability and delinquency history by geographic area. Significant changes in one or more of these considerations may require adjustments affecting net income and net carrying value of accounts receivable. The allowance for doubtful accounts was approximately $0.2 million as of May 29, 2021 and $0.3 million as of both May 30, 2020 and June 1, 2019.2020.

Revenue Recognition

The Company has a number of defined revenue streams across our reportable segments. Distribution is the Company’s largest revenue stream. The distribution business does not include a separate service bundled with the product sold or sold on top of the product. Distribution typically includes products purchased from our suppliers, stocked in our warehouses and then sold to our customers. Revenue is recognized when control of the promised goods is transferred to our customers, which is simultaneous with the title transferring to the customer, in an amount that reflects the transaction price consideration that we expect to receive in exchange for those goods. Control refers to the ability of the customer to direct the use of, and obtain substantially all of, the remaining benefits from the goods. Our transaction price consideration is fixed, unless otherwise disclosed below as variable consideration. Generally, our contracts require our customers to pay for goods after we deliver products to them. Terms are generally on open account, payable net 30 days in North America, and vary throughout Asia/Pacific, Europe and Latin America subject to customary credit checks.

The Company also sells products that are manufactured or assembled in our manufacturing facility. These products can either be built to the customer’s prints/designs or are products that we stock in our warehouse to sell to any customer that places an order. The manufacturing business does not include a separate service bundled with the product sold or sold in addition to the product.

The Company recognizes services revenue when the repair, installation or training is performed. Based on our analysis of services revenue, ASU 2014-09 has an immaterial impact on the timing, amount or characterization of services revenue recognized by the Company. The services we provide are relatively short in duration and typically completed in one toor two weeks. Therefore, at each reporting date, the amount of unbilled work performed is insignificant. The services revenue has consistently accounted for less than 5% of the Company’s total revenues and is expected to continue at that level.

Prior to the adoption of ASU 2014-09, our product sales are recognized as revenue upon shipment, when title passes to the customer, when delivery has occurred or services have been rendered and when collectability is reasonably assured. We also record estimated discounts taken and estimate returns based on our historical experience. Our products are often manufactured to meet the specific design needs of our customers’ applications. Our engineers work closely with customers to ensure that our products will meet their needs. Our customers are under no obligation to compensate us for designing the products we sell.

Inventories, net

Our consolidated inventories are stated at the lower of cost and net realizable value, generally using a weighted-average cost method. Our net inventories include approximately $57.0 million of finished goods, $3.9 million of raw materials and $2.6 million of work-in-progress as of May 29, 2021 as compared to approximately $51.8 million of finished goods, $3.6 million of raw materials and $2.1 million of work-in-progress as of May 30, 2020, as compared to approximately $47.2 million of finished goods, $4.2 million of raw materials and $1.8 million of work-in-progress as of June 1, 2019.2020. The inventory reserve as of May 30, 202029, 2021 was $5.4$5.9 million compared to $4.6$5.4 million as of June 1, 2019.May 30, 2020.

At this time, we do not anticipate any material risks or uncertainties related to possible future inventory write-downs. Provisions for obsolete or slow moving inventories are recorded based upon regular analysis of stock rotation privileges, obsolescence, the exiting of certain markets and assumptions about future demand and market conditions. If future demand changes in an industry or market conditions differ from management’s estimates, additional provisions may be necessary.

We recorded provisions to our inventory reserves of $1.0 million, $1.1$1.0 million and $0.8$1.1 million during fiscal 2021, fiscal 2020 and fiscal 2019, and fiscal 2018, respectively, which were included in cost of sales. The provisions were primarily for obsolete and slow moving parts. The parts were written down to estimated realizable value.

Intangible and Long-Lived Assets

Intangible assets are initially recorded at their fair market values determined by quoted market prices in active markets, if available, or recognized valuation models. Intangible assets that have finite useful lives are amortized over their useful lives either on a straight-line basis or over their projected future cash flows and are tested for impairment when events or changes in circumstances occur that indicate possible impairment. Our intangible assets represent the fair value for trade name, customer relationships, non-compete agreements and technology acquired in connection with the acquisitions.

We review property and equipment, definite-lived intangible assets and other long-lived assets for impairment whenever adverse events or changes in circumstances indicate that the carrying amounts of such assets may not be recoverable.

If adverse events do occur, our impairment review is based on an undiscounted cash flow analysis at the lowest level at which cash flows of the long-lived assets are largely independent of other groups of our assets and liabilities. This analysis requires management judgment with respect to changes in technology, the continued success of product lines and future volume, revenue and expense growth rates. We conduct annual reviews for idle and underutilized equipment and review business plans for possible impairment. Impairment occurs when the carrying value of the assets exceeds the future undiscounted cash flows expected to be earned by the use of the asset or asset group. When impairment is indicated, the estimated future cash flows are then discounted to determine the estimated fair value of the asset or asset group and an impairment charge is recorded for the difference between the carrying value and the estimated fair value.

Additionally, we also evaluate the remaining useful life each reporting period to determine whether events and circumstances warrant a revision to the remaining period of depreciation or amortization. If the estimate of a long livedlong-lived asset’s remaining useful life is changed, the remaining carrying amount of the asset is amortized prospectively over that revised remaining useful life. 

Loss Contingencies

We accrue a liability for loss contingencies when it is probable that a liability has been incurred and the amount can be reasonably estimated. When only a range of possible loss can be established, the most probable amount in the range is accrued. If no amount within this range is a better estimate than any other amount within the range, the minimum amount in the range is accrued. If we determine that there is at least a reasonable possibility that a loss may have been incurred, we will include a disclosure describing the contingency.

Income Taxes

We recognize deferred tax assets and liabilities based on the differences between financial statement carrying amounts and the tax bases of assets and liabilities. We regularly review our deferred tax assets for recoverability and determine the need for a valuation allowance based on a number of factors, including both positive and negative evidence. These factors include historical taxable income or loss, projected future taxable income or loss, the expected timing of the reversals of existing temporary differences and the implementation of tax planning strategies. In circumstances where we, or any of our affiliates, have incurred three years of cumulative losses which constitute significant negative evidence, positive evidence of equal or greater significance is needed to overcome the negative evidence before a tax benefit is recognized for deductible temporary differences and loss carryforwards. See Note 9 “Income Taxes” of the notes to our consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K for further information.

New Accounting Pronouncements

In May 2014, the FASB issued ASU No. 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers, which amends guidance for revenue recognition. ASU 2014-09 is principles based guidance that can be applied to all contracts with customers, enhancing comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets. The core principle of the guidance is that entities should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The guidance details the steps entities should apply to achieve the core principle. In August 2015, the FASB issued an amendment to defer the effective date for all entities by one year. For public entities, ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is permitted as of annual reporting periods beginning after December 15, 2016. Companies have the option of using either a full or modified retrospective approach in applying this standard. During fiscal 2016, 2017, 2018 and 2019 the FASB issued additional updates that further clarify the guidance provided in ASU 2014-09.

Effective June 3, 2018, the Company adopted the standard using the modified retrospective method to all contracts. As a result, financial information for the reporting period beginning June 3, 2018 was reported under the new standard, while comparative financial information has not been adjusted and continues to be reported in accordance with the previous standard. The adoption of this standard did not impact the timing of revenue recognition for our customer sales. The adoption did not result in the recognition of a cumulative adjustment to beginning retained earnings, nor did it have a material impact on the consolidated financial statements. For the Company, the most significant impact of the new standard is the addition of required disclosures within the notes to the financial statements. See Note 4 “Revenue Recognition” of the notes to our consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02 (“ASU 2016-02”), Leases (“Topic 842”). ASU 2016-02 establishes a right-of-use (“ROU”) model that requires a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either financing or operating, with classification affecting the pattern of expense recognition in the income statement. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The new standard was effective for the Company on June 2, 2019. See Note 8 “Lease Obligations and Other Commitments” of the notes to our consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 (as amended by ASU 2018-19, ASU 2019-04, ASU 2019-05, ASU 2019-10, ASU 2019-11 and 2020-02) introduces a new forward-looking approach, based on expected losses, to estimate credit losses on certain types of financial instruments, including trade receivables. The estimate of expected credit losses will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. This ASU also expands the disclosure requirements to enable users of financial statements to understand the entity’s assumptions, models and methods for estimating expected credit losses. The new standard is effective for smaller reporting companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early adoption is permitted. The Company is currently in the process of evaluating the impact of adoption on its consolidated financial statements.

ITEM 7A. Quantitative and QualitativeQualitative Disclosures about Market Risk

Risk Management and Market Sensitive Financial Instruments

We are exposed to many different market risks with the various industries we serve. The primary financial risk we are exposed to is foreign currency exchange, as certain operations, assets and liabilities of ours are denominated in foreign currencies. We manage these risks through normal operating and financing activities.

Foreign Currency Exposure

Even though we take into account current foreign currency exchange rates at the time an order is taken, our financial statements, denominated in a non-U.S. functional currency, are subject to foreign exchange rate fluctuations.

Our foreign denominated assets and liabilities are cash and cash equivalents, accounts receivable, inventory, accounts payable and intercompany receivables and payables, as we conduct business in countries of the European Union, Asia/Pacific and, to a lesser extent, Canada and Latin America. We do manage foreign exchange exposures by using currency clauses in certain sales contracts and we also have local debt to offset asset exposures. We have not used any derivative instruments nor entered into any forward contracts in fiscal 2020,2021, fiscal 20192020 or fiscal 2018.2019.

Had the U.S. dollar changed unfavorably 10% against various foreign currencies, foreign denominated net sales would have been lower by an estimated $10.0 million during fiscal 2021, an estimated $9.3 million during fiscal 2020 and an estimated $10.5 million during fiscal 2019 and an estimated $10.4 million during fiscal 2018.2019. Total assets would have declined by an estimated $4.2 million as of the fiscal year ended May 29, 2021  and an estimated $4.3 million as of the fiscal year ended May 30, 2020, andwhile the total liabilities would have decreased by an estimated $4.7$1.1 million as of the fiscal year ended June 1, 2019, while the total liabilities would have decreased byMay 29, 2021 and an estimated $1.0 million as of the fiscal year ended May 30, 2020 and an estimated $1.1 million as of the fiscal year ended June 1, 2019.2020.

The interpretation and analysis of these disclosures should not be considered in isolation since such variances in exchange rates would likely influence other economic factors. Such factors, which are not readily quantifiable, would likely also affect our operations. Additional disclosure regarding various market risks are set forth in Part I, Item 1A “Risk Factors”, Risk Factors, of our Annual Report on this Form 10-K.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Richardson Electronics, Ltd. (the “Company”) as of May 29, 2021 and May 30, 2020, and June 1, 2019, the related consolidated statements of comprehensive income (loss) income,, stockholders’ equity, and cash flows for each of the three years in the period ended May 30, 2020,29, 2021, 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 May 29, 2021 and May 30, 2020, and June 1, 2019, and the results of its operations and its cash flows for each of the three years in the period ended May 30, 202029, 2021, in conformity with accounting principles generally accepted in the United States of America.

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 May 30, 2020,29, 2021, based on criteria established in Internal Control – Integrated Framework (2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) and our report dated August 3, 20202, 2021 expressed an unqualified opinion thereon.

Change in the Accounting Method Related to Leases

As discussed in Notes 3 and 8Note 6 to the consolidated financial statements, the Company has changed its method of accounting for leases during the year ended May 30, 2020 due to the adoption of Accounting Standards Codification Topic 842, Leases.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated 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 PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated 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 regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgements. The communication of a critical audit matter 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 matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.  

Estimation of Inventory Reserve - Power and Microwave Technologies ("PMT") Group

As described in Note 3 to the consolidated financial statements, the consolidated inventory balance as of May 29, 2021 was $63.5 million, net of $5.9 million in reserves. Inventories are stated at the lower of cost and net realizable value. Provisions for obsolete or slow-moving inventories are based upon regular analysis of obsolescence, the exiting of certain markets and assumptions about future demand and market conditions. A number of products in the PMT segment represent trailing edge technology. PMT often buys products ahead of supplier price increases and extended lead times which can create surplus inventory. As technologies evolve and customers replace their capital equipment, the market for and resulting net realizable value of PMT's products may decline.

We have identified the Company's estimation of inventory reserve for the PMT segment as a critical audit matter due to the significant judgments required by management in estimating future demand for each individual inventory item. The Company's forecasted demand, performed on an item-by-item basis, requires inputs from operations personnel and assessment of current market conditions and future industry trends, which can be difficult to predict given evolving technologies and the declining market for some products. Auditing this matter involved especially challenging auditor judgment due to the nature and extent of audit effort needed to evaluate the reasonableness of the assumptions and judgements made by management.  

The primary procedures we performed to address this critical audit matter included:
