PART I

Item 1. Business.

Cohu is a leading supplier of semiconductor test and inspection handlers, micro-electromechanical system (MEMS) test modules, test contactors, thermal sub-systems, semiconductor automated test equipment and bare board PCB test systems used by global semiconductor and electronics manufacturers and semiconductor test subcontractors. We offer a wide range of products and services, and revenue from our capital equipment products is driven by the capital expenditure budgets and spending patterns of our customers, who often delay or accelerate purchases in reaction to variations in their business. The level of capital expenditures by these companies depends on the current and anticipated market demand for semiconductor devices and PCBs and the products that incorporate them. Our recurring revenues are driven by an increase in the number of semiconductor devices and PCBs that are tested and by the continuous introduction of new products and technologies by our customers.

On October 1, 2018, we acquired Xcerra Corporation (“Xcerra”), a Massachusetts-based company. Xcerra, formerly known as LTX-Credence Corporation, is a global provider of test and handling capital equipment, interface products and related services to the semiconductor and electronics manufacturing industries. Xcerra operated in semiconductor and electronics manufacturing test markets through its atg-Luther & Maelzer, Everett Charles Technologies (ECT), LTX-Credence and Multitest businesses. The acquisition of Xcerra extended Cohu’s market position in the test handler and test contactor markets and expanded Cohu’s addressable market with our entry into semiconductor automated test equipment (ATE) and bare board PCB test. The results of Xcerra’s operations have been included in our consolidated results since October 1, 2018. As a result of the timing of the acquisition, our fiscal 2020 and 2019 results include Xcerra for the entire year whereas fiscal 2018 amounts only include Xcerra for the three months ended December 29, 2018. This acquisition helped transform our business into a broader semiconductor test, inspection and test handling market leader with greater scale, diversification and market opportunities.

Management previously determined that Xcerra’s fixtures services business did not align with Cohu’s long-term strategic plan and engaged in a process to divest this portion of the business. As a result, as of December 28, 2019 and December 29, 2018, the assets of our fixtures business are considered “held for sale” and the operations of our fixtures business were presented as “discontinued operations”. This business was sold in February 2020. Unless otherwise noted, all amounts presented are from continuing operations.

We have determined that we have two reportable segments, Semiconductor Test and Inspection Equipment (“Semiconductor Test & Inspection”) and PCB Test Equipment (“PCB Test”). Financial information on our reportable segments for each of the last three years is included in Note 10, “Segment and Geographic Information” in Part IV, Item 15(a) of this Form 10-K.

Sales by reportable segment, expressed as a percentage of total consolidated net sales, for the last three years were as follows:

Cohu, Inc. (“Cohu”, “we”, “our”, “us” and the “Company”) was incorporated under the laws of California in 1947, as Kalbfell Lab, Inc. and commenced active operations in the same year. Our name was changed to Kay Lab in 1954. In 1957, Cohu was reincorporated under the laws of the State of Delaware as Cohu Electronics, Inc. and in 1972 our name was changed to Cohu, Inc.

Our Products

We currently sell the following products:

Semiconductor Test. Semiconductor ATE (Automated Test Equipment) is used both for wafer level and device package testing. Our semiconductor ATE solutions consist primarily of two platforms focused on the system on a chip (SoC) device market. The Diamond series platform, which includes the flagship Diamondx test system, offers high-density instrumentation for low-cost testing of microcontrollers, application specific standard products (ASSP), power management, display drivers, sensors and other mixed signal devices. The PAx series of testers is focused primarily on the RF Front End IC and Module market.

Semiconductor Handlers. Semiconductor test handlers are used in conjunction with semiconductor ATE to automate the testing of packaged semiconductor devices. Our handlers support a variety of package sizes and device types, including those used in automotive, mobile, industrial, computing applications, among others. We offer a broad range of test handlers, including pick-and-place, turret, gravity, strip, MEMS and thermal sub-systems, along with inspection handlers that perform automated optical inspection of semiconductor devices.

Interface Products. Our interface products are comprised of test contactors, probe heads and probe pins. Test contactors serve as the interface between the test handler and the semiconductor device under test such as digital semiconductor devices utilizing spring probe technology, power management and LED semiconductor devices utilizing cantilever technology, and RF semiconductor devices based on contacts designed to operate at high frequencies. Test contactors and probe heads are specific to individual semiconductor device designs, need to be replaced frequently and increase in size with the number of devices tested in parallel. Interface Products are included in our recurring revenues.

Spares and Kits. We provide consumable, non-consumable and spare items that are used to maintain, sustain or otherwise enable customers’ equipment to meet its performance, availability and production requirements. We also design and manufacture a wide range of device dedication kits that enable handlers to process different semiconductor packages. Spares and Kits are included in our recurring revenues.

Services. Our worldwide service organization performs installations and necessary maintenance of systems sold. We provide various parts and labor warranties on test and handling systems and instruments designed and manufactured by us and warranties on certain components that have been purchased from other manufacturers and incorporated into our test and handling systems. We also provide training on the maintenance and operation of our systems as well as application, data management software and consulting services on our products. Our InSight test cell enterprise software platform provides our customers with a centralized data management system to monitor equipment performance. Services are included in our recurring revenues.

Bare Board PCB Test Systems. Bare board PCB test systems are used to test pre-assembly printed circuit boards. Our PCB test systems include flying probe testers, which are used to test low-volume, highly complex circuit boards and do not require the use of a separate test fixture, as well as universal grid testers, which require the use of a custom test fixture and are well-suited for circuit boards in high volume manufacturing.

Sales by Product Line

During the last three years, our consolidated net sales were distributed as follows:

Customers

Our customers include semiconductor integrated device manufacturers, fabless design houses, PCB manufacturers, and test subcontractors throughout the world. Repeat sales to existing customers represent a significant portion of our sales. During the last three years, customers of our Semiconductor Test & Inspection segment that comprised 10% or greater of our consolidated net sales were as follows:

No customer of our PCB Test segment exceeded 10% of consolidated net sales for the years ended December 26, 2020, December 28, 2019 or December 29, 2018.

The loss of, or a significant reduction in, orders by these or other significant customers, including reductions due to market, economic or competitive conditions or the outsourcing of final integrated circuit test to subcontractors that are not our customers would adversely affect our financial condition and results of operations.

Additional financial information on revenues from external customers by geographic area for each of the last three years is included in Note 10, “Segment and Geographic Information” in Part IV, Item 15(a) of this Form 10-K.

Sales and Marketing

We market our products worldwide through a combination of a direct sales force and independent sales representatives. In geographic areas where we believe there is sufficient sales potential, we generally employ our own personnel. Our United States, (U.S.) sales offices are located in Poway and Milpitas, California, Lincoln, Rhode Island and Norwood, Massachusetts. Our European sales offices are located in Wertheim and Kolbermoor, Germany; Grenoble, France; Agrate, Italy and La Chaux-de-Fonds, Switzerland. We operate in Asia with sales and service offices in Singapore, Malaysia, Thailand, Philippines, Taiwan, China, South Korea and Japan.

Competition

The semiconductor equipment and PCB test industries are intensely competitive and are characterized by rapid technological change and demanding worldwide service requirements. Significant competitive factors include product performance, price, reliability, lead-time, customer support and installed base of products. While we believe that we are the leading worldwide supplier of semiconductor test handling equipment, we face substantial competition in Japan and Taiwan which represent a significant percentage of the worldwide market. Test subcontractors in Asia also purchase mostly from local Asian competitors. In the semiconductor test market, we face competition from two dominant suppliers headquartered in the U.S. and Japan, both of which are substantially larger than Cohu’s test business. While we are among the leading worldwide suppliers of test contactors, this market is fragmented with a large number of global and local competitors. Further, the PCB test industry is characterized by significant Asia-based competition and intense price competition. To remain competitive within the industries we serve, we believe we will require significant financial resources to offer a broad range of products, maintain localized customer support and service centers worldwide and to invest in research and development of new products. Failure to introduce new products in a timely manner or the introduction by competitors of products with actual or perceived advantages could result in a loss of competitive position and reduced sales of existing products. No assurance can be given that we will continue to compete successfully throughout the world.

Backlog

Our backlog of unfilled orders for products, by segment at December 26, 2020 and December 28, 2019 was as follows:

Backlog is generally expected to ship within the next twelve months. Our backlog at any point in time may not be representative of actual sales in any future period due to the possibility of customer changes in delivery schedules, cancellation of orders, potential delays in product shipments, and difficulties in obtaining parts from suppliers or failure to satisfy customer acceptance requirements resulting in the inability to recognize revenue under accounting requirements. Furthermore, many orders are subject to cancellation or rescheduling by the customer with limited or no penalty. A reduction in backlog during any period could have a material adverse effect on our business, financial condition and results of operations.

Manufacturing and Raw Materials

Our principal manufacturing operations are currently located in Malacca, Malaysia (handler operations and kits); Laguna, Philippines (kits and test contactors); Lincoln, Rhode Island (connectors); Osaka, Japan (probe pins); and Wertheim, Germany (bare board PCB test systems).

We outsource the manufacturing of many of our semiconductor automated test equipment products to Jabil Circuit, Inc’s facility in Penang, Malaysia. Our contract manufacturing partner is responsible for significant material procurement, assembly and testing. We continue to manage product design through pilot production for the subcontracted products, and we are directly involved in qualifying suppliers and key components used in all our products. Our contract manufacturer is responsible for funding the capital expenses incurred in connection with the manufacture of our products, except with regard to end-of-line testing equipment and other specific manufacturing equipment utilized in assembling our products or sub-components which are financed and owned by Cohu. Contracting with a global provider such as Jabil, gives us added flexibility to manufacture certain products closer to target markets in Asia, potentially increasing responsiveness to customers while reducing costs and delivery times.

Many of the components and subassemblies we utilize are standard products, although some items are made to our specifications. Certain components are obtained or are available from a limited number of suppliers. We seek to reduce our dependence on sole and limited source suppliers, however in some cases the complete or partial loss of certain of these sources could have a material adverse effect on our operations while we attempt to locate and qualify replacement suppliers.

Patents and Trademarks

Our technology is protected by various intellectual property laws including patent, license, trademark, copyright and trade secret laws. In addition, we believe that, due to the rapid pace of technological change in the semiconductor and electronic equipment industries, the successful manufacture and sale of our products also depends upon our experience, technological know-how, manufacturing and marketing skills and speed of response to sales opportunities. In the absence of patent protection, we would be vulnerable to competitors who attempt to copy or imitate our products or processes. We believe our intellectual property has value and we have in the past and will in the future take actions we deem appropriate to protect such property from misappropriation. However, there can be no assurance such actions will provide meaningful protection from competition. Protecting our intellectual property rights or defending against claims brought by other holders of such rights, either directly against us or against customers we have agreed to indemnify, would likely be expensive and time consuming and could have a material adverse effect on our operations.

Research and Development

Research and development activities are carried on in our various subsidiaries and are directed toward development of new products and equipment, as well as enhancements to existing products and equipment. Our total research and development expense was $86.2 million in 2020, $86.1 million in 2019 and $56.4 million in 2018. The increase in research and development expense in 2019 was primarily associated with the acquisition of Xcerra on October 1, 2018. Incremental research and development expense directly attributed to Xcerra in 2020, 2019 and 2018 was $44.2 million, $45.4 million and $11.5 million, respectively.

We work closely with our customers to make improvements to our existing products and in the development of new products. We expect to continue to invest heavily in research and development and must manage product transitions successfully as introductions of new products could adversely impact sales.

Seasonality

Historically, the semiconductor industry has been seasonal with recurring periods of oversupply and excess capacity, which often have had a significant effect on the semiconductor industry’s demand for capital equipment, including equipment of the type we manufacture and market. We anticipate that the markets for newer generations of semiconductors and semiconductor equipment will be subject to similar cycles and severe downturns. Any significant reductions in capital equipment investment by semiconductor integrated device manufacturers and test subcontractors will materially and adversely affect our business, financial position and results of operations. See the risk factor entitled “The semiconductor industry we serve is seasonal, volatile and unpredictable.”

Risks Relating to Our Business Operations and Industry

The ongoing global COVID-19 pandemic has adversely affected, and is continuing to adversely affect, our business, financial condition and results of operations.

The ongoing global COVID-19 pandemic has adversely affected, and is continuing to adversely affect, our business, financial condition and results of operations. As the COVID-19 virus has spread rapidly and globally, from March 2020 and continuing to the present, authorities have implemented numerous measures to try to contain the virus, such as travel bans and restrictions, quarantines, shelter in place orders, and shutdowns, including in all of the jurisdictions where we operate. These measures have adversely impacted, and are continuing to adversely impact, our workforce and operations, the operations of our customers, and those of our respective vendors and suppliers. We have significant operations in the U.S., Germany, Switzerland, Malaysia, Japan and the Philippines, and each of these countries has been significantly affected by the COVID-19 outbreak. During the COVID-19 pandemic, it has been common for restrictions to be implemented, relaxed and then implemented again with little or no notice, which adversely impacts our ability to accurately predict our future revenue and budget future expenses and is disruptive to our operations.

Although we believe that Cohu qualifies as an “essential business” in the jurisdictions in which we operate, our business has been, and is continuing to be, adversely impacted by evolving and extended public health requirements around the world; government-mandated facility shutdowns; import/export, shipping and logistics disruptions and delays; other supply chain and distribution constraints or delays; rapid changes to business, political or regulatory conditions affecting the semiconductor equipment industry and the overall global economy; availability of employees and lost employee productivity; risks associated with, at times, temporarily housing employees in our Malaysia and Philippines factories; remote working IT and increased cybersecurity risks; increased internal control risks over financial reporting as key finance staff work remotely; delayed product development programs; customers’ canceling, pushing out orders or refusal to accept product deliveries; delayed collection of receivables; other actions of our customers, suppliers and competitors which may be sudden and inconsistent with our expectations; higher shipping and logistics costs; higher component costs; manufacturing capacity limitations; additional credit rating agency downgrades could occur which would increase our cost of raising capital; and potential additional impairment of goodwill or other intangible assets or inventory write-downs due to lower product demand may become necessary. Any of the foregoing COVID-19 driven impacts may have a material adverse effect on our financial condition and results of operations, and may also have the effect of increasing the likelihood and/or magnitude of other risks described in these risk factors. We continuously monitor the pandemic but cannot predict its future course or impacts.

We are making investments in new products and product enhancements, which may adversely affect our operating results; these investments may not be commercially successful.

Given the highly competitive and rapidly evolving technology environment in which we operate, we believe it is important to develop new and enhanced product offerings to meet strategic opportunities as they evolve. This includes developing products that we believe are necessary to meet the future needs of the marketplace and to enter new markets. We are currently significantly investing in new product development programs relating to test contactors, test handlers and automated test equipment. For example, in fiscal 2020, we incurred $86.2 million in research and development expenses. We expect to continue to make investments and we may, at any time, based on product need or marketplace demand, decide to significantly increase our product development expenditures in these or other products. The cost of investments in new product offerings and product enhancements can have a negative impact on our operating results. We have in the past made material investments in new product platforms that for various reasons, such as technical challenges or lack of customer adoption, have not generated the expected sales or return. There can be no assurance that other new products we develop will be accepted in the marketplace or generate material revenues for us.

We are exposed to the risks of operating a global business.

We are a global corporation with offices and subsidiaries in certain foreign locations to manufacture our products, support our sales and services to the global semiconductor industry and, as such, we face risks in doing business abroad. For example, while our corporate headquarters are located in California, additional key engineering, sales, and administrative personnel are located in China, Germany, Japan, Malaysia, Philippines, Singapore, Switzerland, Taiwan and elsewhere in the U.S., and our manufacturing operations are primarily located in Germany, Japan, Malaysia, Philippines and the U.S. Certain aspects inherent in transacting business internationally could negatively impact our operating results, including:

Additionally, managing geographically dispersed operations presents difficult challenges associated with organizational alignment and infrastructure, communications and information technology, inventory control, customer relationship management, terrorist threats and related security matters and cultural diversities. If we are unsuccessful in managing such operations effectively, our business and results of operations will be adversely affected.

We continue to monitor global privacy laws and legislation to determine its impact on our business. We do not sell to consumers nor process individual credit card information, but do maintain certain personally identifiable information on our employees. Such employee information may be subject to the EU General Data Protection Regulation and the recently effective California Consumer Protection Act. We believe that we have implemented reasonable procedures and internal controls in compliance with these laws, but should such actions be insufficient, we may be subject to regulatory investigations, fines and legal costs. If one or more of these risks occurs, it could require us to dedicate significant resources to remedy, and if we are unsuccessful in finding a solution, our financial results will suffer.

We have manufacturing operations in Asia. Any failure to effectively manage multiple manufacturing sites and to secure raw materials meeting our quality, cost and other requirements, or failures by our suppliers to perform, could harm our sales, service levels and reputation.

A substantial majority of our products are manufactured in Asia. Our reliance on overseas manufacturers exposes us to significant risks including complex management, foreign currency, legal, tax and economic risks, which we may not be able to address quickly and adequately. In addition, it is time consuming and costly to qualify overseas supplier relationships. If we should fail to effectively manage overseas manufacturing operations or logistics, or if one or more of them should experience delays, disruptions or quality control problems, or if we had to change or add additional manufacturing sites, our ability to ship products to our customers could be delayed. Also, the addition of overseas manufacturing locations increases the demands on our administrative and operations infrastructure and the complexity of our supply chain management and logistics. Our overseas sites are more susceptible to impacts from natural disasters, health epidemics and geopolitical instability (see risk factors entitled “The ongoing global COVID-19 pandemic has adversely affected, and is continuing to adversely affect, our business, financial condition and results of operations” and “The occurrence of natural disasters, health epidemics, corruption and geopolitical instability caused by terrorist attacks and other threats may adversely impact our operations and sales”). If our overseas manufacturing locations are unable to meet our manufacturing requirements in a timely manner, our ability to ship products and to realize the related revenues when anticipated could be materially affected.

Our suppliers are subject to the fluctuations in general economic cycles, and global economic conditions may impact their ability to operate their businesses. They may also be impacted by possible import, export, tariff and other trade barriers, increasing costs of raw materials, labor and distribution, resulting in demands for less attractive contract terms or an inability for them to meet our requirements or conduct their own businesses. Additionally, consolidation in our supply chain due to mergers and acquisitions may reduce the number of suppliers or change our relationships with them. The performance and financial condition of a supplier may cause us to alter our business terms or to cease doing business with a particular supplier, or change our sourcing practices generally, which could in turn adversely affect our own business and financial condition. Failure to effectively manage our manufacturing and our relationships with our suppliers could have a material adverse effect on our business and results of operations.

Failure of critical suppliers to deliver sufficient quantities of parts in a timely and cost-effective manner could adversely impact our operations.

We use numerous vendors to supply parts, components and subassemblies for the manufacture of our products. It is not always possible to maintain multiple qualified suppliers for all of our parts, components and subassemblies. As a result, many key parts may be available only from a single supplier (“sole source”) or a limited number of suppliers. In addition, suppliers may significantly raise prices or cease manufacturing certain components (with or without advance notice to us) that are difficult to replace without significant reengineering of our products. On occasion, we have experienced problems in obtaining adequate and reliable quantities of various parts and components from certain key or sole source suppliers. Our results of operations may be materially and adversely impacted if we do not receive sufficient parts to meet our requirements in a timely and cost-effective manner.

The semiconductor industry we serve is seasonal, volatile and unpredictable.

Visibility into our markets is limited. The semiconductor equipment business is highly dependent on the overall strength of the semiconductor industry. Historically, the semiconductor industry has been seasonal with recurring periods of oversupply and excess capacity, which often have had a significant effect on the semiconductor industry’s demand for capital equipment, including equipment of the type we manufacture and market. We anticipate that the markets for newer generations of semiconductors and semiconductor equipment will also be subject to similar cycles and severe downturns. Any significant reductions in capital equipment investment by semiconductor integrated device manufacturers and test subcontractors will materially and adversely affect our business, financial position and results of operations. In addition, the seasonal, volatile and unpredictable nature of semiconductor equipment demand has in the past and may in the future expose us to significant excess and obsolete and lower of cost or net realizable value inventory write-offs and reserve requirements. In 2020, 2019 and 2018, we recorded pre-tax inventory-related charges of approximately $6.0 million, $4.1 million, and $1.4 million, respectively, primarily as a result of changes in customer forecasts. We saw weakness in market conditions in 2019, followed by COVID-19 driven uncertainties in 2020, then a significant market recovery beginning in third quarter 2020. Abrupt, unexpected and severe demand changes have occurred in the past and are expected to reoccur in the future within our industry.

The semiconductor equipment and PCB test industries are intensely competitive.

The industries we serve are intensely competitive, and we face substantial competition from numerous companies throughout the world. The test handler industry, while relatively small in terms of worldwide market size compared to other segments of the semiconductor equipment industry, has several participants resulting in intense competitive pricing pressures. Future competition may include companies that do not currently supply test handlers. Similarly, the PCB test industry is characterized by significant Asia-based competition and intense price competition. Some of our competitors are part of larger corporations that have substantially greater financial, engineering, manufacturing and customer support capabilities and provide more extensive product offerings. In addition, there are emerging companies that provide or may provide innovative technology incorporated in products that may compete successfully against our products. We expect our competitors to continue to improve the design and performance of their current products and introduce new products with improved performance capabilities. Our failure to introduce new products in a timely manner, the introduction by our competitors of products with perceived or actual advantages, or disputes over rights to use certain intellectual property or technology could result in a loss of our competitive position and reduced sales of, or margins on our existing products. Intense competition has adversely impacted our product average selling prices and gross margins on certain products. If we are unable to reduce the cost of our existing products and successfully introduce new lower cost products, then we expect that these competitive conditions would negatively impact our gross margin and operating results in the foreseeable future.

We have increased investments in our test contactor business and announced significant growth targets for the business over the next several years, but due to weak market conditions we did not achieve our growth goals in 2019 and 2020. The test contactor market is fragmented, with many entrenched regional players, and subject to intense price competition and high localized customer support requirements. We believe that customer support and responsiveness and an ability to consistently meet tight deadlines is critical to our success. If we are unable to reduce the cost of our test contactor products, while also meeting customer support requirements and deadlines, then we expect that these competitive conditions would negatively impact our test contactor operating results and impede us from achieving our test contactor sales goals.

In addition, with the Xcerra acquisition, Cohu entered the automated test equipment (“ATE”) market. Our ability to increase our ATE sales will depend, in part, on our ability to obtain orders from new customers. Semiconductor and electronics manufacturers typically select a particular vendor’s product for testing new generations of a device and make substantial investments to develop related test program applications and interfaces. Once a manufacturer has selected an ATE vendor for a new generation of a device, that manufacturer is more likely to purchase systems from that vendor for that generation of the device, and, possibly, subsequent generations of that device as well. Cohu has a niche position and relatively low share in the ATE market, and this market is primarily driven by two larger companies with significantly more resources to invest into the ATE market. Therefore, the opportunities to obtain orders from new customers or existing customers may be limited, which may impair our ability to grow our ATE revenue. These factors may materially and adversely affect our current and future target markets and our ability to compete successfully in those markets.

Semiconductor equipment is subject to rapid technological change, product introductions and transitions which may result in inventory write-offs, and our new product development involves numerous risks and uncertainties.

Semiconductor equipment and processes are subject to rapid technological change. We believe that our future success will depend in part on our ability to enhance existing products and develop new products with improved performance capabilities. We expect to continue to invest heavily in research and development and must manage product transitions successfully, as introductions of new products, including the products obtained in our acquisitions, may adversely impact sales and/or margins of existing products. In addition, the introduction of new products by us or by our competitors, the concentration of our revenues in a limited number of large customers, the migration to new semiconductor testing methodologies and the custom nature of our inventory parts increases the risk that our established products and related inventory may become obsolete, resulting in significant excess and obsolete inventory exposure. This exposure resulted in charges to operations during each of the years in the three-year period ended December 26, 2020. Future inventory write-offs and increased inventory reserve requirements could have a material adverse impact on our results of operations and financial condition.

The design, development, commercial introduction and manufacture of new semiconductor equipment is an inherently complex process that involves a number of risks and uncertainties. These risks include potential problems in meeting customer acceptance and performance requirements, integration of the equipment with other suppliers’ equipment and the customers’ manufacturing processes, transitioning from product development to volume manufacturing and the ability of the equipment to satisfy the semiconductor industry’s constantly evolving needs and achieve commercial acceptance at prices that produce satisfactory profit margins. The design and development of new semiconductor equipment is heavily influenced by changes in integrated circuit assembly, test and final manufacturing processes and integrated circuit package design changes. We believe that the rate of change in such processes and integrated circuit packages is accelerating. As a result of these changes and other factors, assessing the market potential and commercial viability of test handling, ATE, MEMS, system-level and burn-in test equipment and test contactors is extremely difficult and subject to a great deal of risk. In addition, not all integrated circuit manufacturers employ the same manufacturing processes. Differences in such processes make it difficult to design standard test products that can achieve broad market acceptance. As a result, we might not accurately assess the semiconductor industry’s future equipment requirements and fail to design and develop products that meet such requirements and achieve market acceptance. Failure to accurately assess customer requirements and market trends for new semiconductor test products may have a material adverse impact on our operations, financial condition and results of operations.

The transition from product development to the manufacture of new semiconductor equipment is a difficult process and delays in product introductions and problems in manufacturing such equipment are common. We have in the past and may in the future experience difficulties in manufacturing and volume production of our new equipment. In addition, as is common with semiconductor equipment, after sale support and warranty costs have typically been significantly higher with new products than with our established products. Future technologies, processes and product developments may render our current or future product offerings obsolete and we might not be able to develop, introduce and successfully manufacture new products or make enhancements to our existing products in a timely manner to satisfy customer requirements or achieve market acceptance. Furthermore, we might not realize acceptable profit margins on such products.

The seasonal nature of the semiconductor equipment industry places enormous demands on our employees, operations and infrastructure.

The semiconductor equipment industry is characterized by dramatic and sometimes rapid changes in demand for its products. These are generally dictated by introduction of new consumer products, launch of new model vehicles, implementation of new communications infrastructure, or in response to an increase in industrial equipment and machinery that utilizes semiconductors. A number of other factors including changes in integrated circuit design and packaging may affect demand for our products. Sudden changes in demand for semiconductor equipment commonly occur, and have a significant impact on our operations, and such changes in demand (up or down) are difficult to predict and proactively plan for. We have in the past and may in the future experience difficulties, particularly in manufacturing, in training and recruiting the large number of additions to our workforce. The volatility in headcount and business levels, combined with the seasonal nature of the semiconductor industry, may require that we invest substantial amounts in new operational and financial systems, procedures and controls. We may not be able to successfully adjust our systems, facilities and production capacity to meet our customers’ changing requirements. Any inability to meet such requirements will have an adverse impact on our business, financial position and results of operations. Sudden demand changes (as, for example, we experienced in 2019 and 2020) in business conditions, positive or negative, are common in our industry but the timing of such changes is very difficult to predict.

A limited number of customers account for a substantial percentage of our net sales.

A small number of customers have been responsible for a significant portion of our net sales. For fiscal year 2020, net revenue from our ten largest customers represented 47% of our total net revenue. During the past five years, the percentage of our sales derived from these significant customers has varied greatly. Such variations are due to changes in the customers’ business, consolidation within the semiconductor industry and their purchase of products from our competitors. It is common in the semiconductor equipment industry for customers to purchase products from more than one equipment supplier, increasing the risk that our competitive position with a specific customer may deteriorate. No assurance can be given that we will continue to maintain our competitive position with these or other significant customers. Also, consolidation in the semiconductor industry may reduce our customer base and could adversely affect the market for our products, which could cause a decline in our revenues. With consolidation, the number of actual and potential customers for our products has decreased in recent years. Consolidation may lead to relatively fewer opportunities to sell our products if we are not chosen as a supplier by any given prospective customer, and may lead to increased pricing pressures from customers that have greater volume purchasing power.

We expect the percentage of our revenues derived from significant customers will vary greatly in future periods. The loss of, or a significant reduction in, orders by these or other significant customers as a result of competitive products, market conditions including end market demand for our customers’ products, outsourcing final semiconductor test to test subcontractors that are not our customers or other factors, would have a material adverse impact on our business, financial condition and results of operations. Furthermore, the concentration of our revenues in a limited number of large customers is likely to cause significant fluctuations in our future annual and quarterly operating results.

A majority of our revenues are generated from exports to foreign countries, primarily in Asia, that are subject to economic and political instability and we compete against a number of Asia-based test contactor, test handler, automated test equipment and PCB test suppliers.

The majority of our export sales are made to destinations in Asia. Political or economic instability, particularly in Asia, may adversely impact the demand for capital equipment, including equipment of the type we manufacture and market (see risk factor “Global economic and political conditions, including trade tariffs and export restrictions, have impacted our business and may continue to have an impact on our business and financial condition”). In addition, we face intense competition from a number of Asian suppliers that have certain advantages over United States (U.S.) suppliers, including us. These advantages include, among other things, proximity to customers, lower cost structures, a willingness to compete solely on price, favorable tariffs and affiliation with significantly larger organizations. In addition, changes in the amount or price of semiconductors produced in Asia could impact the profitability or capital equipment spending programs of our foreign and domestic customers.

If we cannot continue to develop, manufacture, market and support products and services that meet customer requirements for innovation and quality, our revenue and gross margin may suffer.

The process of developing new high technology products and services and enhancing existing products and services is complex, costly and uncertain, and any failure by us to anticipate customers’ changing needs and emerging technological trends accurately could significantly harm our sales and results of operations. Our customers’ selection processes typically are lengthy and can require us to incur significant sales, service and engineering resources, and regularly to provide the customer evaluation systems for several months at no charge, in pursuit of a single customer opportunity. We may not win the competitive selection process and may never generate any revenue despite incurring such expenditures. The delays inherent in these lengthy sales cycles increase the risk that a customer will decide to cancel, curtail, reduce or delay its product plans, causing us to lose anticipated sales.

In addition, in the course of conducting our business, we must adequately address quality issues associated with our products and services, including defects in our engineering, design and manufacturing processes, as well as defects in third-party components included in our products. To address quality issues, we work extensively with our customers and suppliers and engage in product testing to determine the cause of quality problems and appropriate solutions. Finding solutions to quality issues can be expensive and may result in additional warranty, replacement and other costs. In addition, if any of our products contain defects or have reliability, quality or safety issues, we may need to conduct a product recall which could result in significant repair or replacement costs and substantial delays in product shipments and may damage our reputation, which could make it more difficult to sell our products. Any of these occurrences could have a material adverse effect on our business, results of operations or financial condition. In addition, quality issues can impair our relationships with new or existing customers and adversely affect our reputation, which could lead to a material adverse effect on our operating results.

Our global Enterprise Resource Management (“ERP”) upgrade may adversely affect our business and results of operations or the effectiveness of internal controls over financial reporting.

We are in final development stages of a phased global replacement of our existing ERP solution and launched the first phase of such new ERP solution in first and fourth quarter 2020. The second phase and rollout is planned throughout 2021. The new solution is being developed as an enterprise solution in partnership with a leading provider of ERP tools. Additional investments in enterprise tools that focus on product life-cycle management, our customer experience, and supply chain management are in process to support our growing business. These implementations are extremely complex and time-consuming projects that involve substantial expenditures on software and implementation activities. If we do not effectively implement the system or if the system does not operate as intended, it could result in the loss or corruption of data, delayed order processing and shipments and increased costs. It could also adversely affect our financial reporting systems and our ability to produce financial reports and process transactions, the effectiveness of internal controls over financial reporting, and our business, financial condition, results of operations and cash flows.

The loss of key personnel could adversely impact our business.

Certain key personnel are critical to our business. Our future operating results depend substantially upon the continued service of our key personnel, many of whom are not bound by employment or non-competition agreements. Our future operating results also depend in significant part upon our ability to attract and retain qualified management, manufacturing, technical, engineering, marketing, sales and support personnel. Competition for qualified personnel, particularly those with technical skills, is intense, and we cannot ensure success in attracting or retaining qualified personnel. In addition, the cost of living in the San Diego and Bay Area, California; Boston, Massachusetts; St. Paul, Minnesota; Lincoln, Rhode Island; Kolbermoor and Wertheim, Germany; La Chaux-de-Fonds, Switzerland and Osaka, Japan areas, where the majority of our engineering personnel are located, is high and we have had difficulty in recruiting prospective employees from other locations. There may be only a limited number of persons with the requisite skills and relevant industry experience to serve in these positions and it may become increasingly difficult for us to hire personnel over time. More recently, the COVID-19 pandemic has increased the risks that our executives and other key employees may be suddenly unable to perform their duties due to health or other personal responsibilities. Our business, financial condition and results of operations could be materially adversely affected by the loss of any of our key employees, by the failure of any key employee to perform in his or her current position, or by our inability to attract and retain skilled employees.

Third parties may violate our proprietary rights or accuse us of infringing upon their proprietary rights.

We rely on patent, copyright, trademark and trade secret laws to establish and maintain proprietary rights in our technology and products. Any of our proprietary rights may expire due to patent life, or be challenged, invalidated or circumvented. In addition, from time-to-time, we receive notices from third parties regarding patent or copyright claims. Any such claims, with or without merit, could be time-consuming to defend, result in costly litigation, divert management’s attention and resources and cause us to incur significant expenses. In the event of a successful claim of infringement against us and our failure or inability to license the infringed technology or to substitute similar non-infringing technology, our business, financial condition and results of operations could be adversely affected. We are also subject to the theft and misappropriation of intellectual property by others, including incidents relating to former employees. We believe we are taking reasonable actions to protect and improve our security, through strengthened IT infrastructure and internal controls, but if these actions are not successful our business could be adversely affected.

Risks Relating to our Indebtedness, Financing and Future Access to Capital

The incurrence of substantial indebtedness in connection with our financing of the Xcerra acquisition may have an adverse impact on Cohu’s liquidity, limit Cohu’s flexibility in responding to other business opportunities and increase Cohu’s vulnerability to adverse economic and industry conditions.

In connection with the Xcerra acquisition, Cohu entered into a term loan facility, with an aggregate principal amount of $350.0 million (the “Debt Financing” or “Credit Agreement”). Such indebtedness has reduced Cohu’s liquidity and has caused Cohu to place more reliance on cash generated from operations to pay principal and interest on Cohu’s debt, thereby reducing the availability of Cohu’s cash flow for working capital and capital expenditure needs or to pursue other potential strategic plans. In addition, our indebtedness may make us more vulnerable to changes in general economic conditions and/or a downturn in our business, thereby making it more difficult for us to satisfy our obligations. During the second half of 2020, Cohu took action to reduce outstanding principal under its Debt Financing; however, Cohu gives no future assurance as to if, when or how much any subsequent voluntary principal reductions may be. If we fail to make required debt payments, or if we fail to comply with financial or other covenants in our Credit Agreement, we would be in default under the agreement.

Our Credit Agreement contains various representations and negative covenants that limit, subject to certain exceptions and baskets, our ability and/or our subsidiaries’ ability to, among other things:

The restrictions contained in our Credit Agreement could adversely affect our ability to:

A breach of any of these negative covenants could result in a default under the Credit Agreement. Further, additional indebtedness that we incur in the future may subject us to further covenants. Our failure to comply with these covenants could result in a default under the agreements governing the relevant indebtedness. The lender may accelerate the payment terms of the Credit Agreement upon the occurrence of certain events of default set forth therein, which include: the failure of Cohu to make timely payments of amounts due under the Credit Agreement, the failure of Cohu to adhere to the representations and covenants set forth in the Credit Agreement, the failure to provide notice of any event that causes a material adverse effect or to provide other required notices, upon the event that related collateral agreements become ineffective, upon the event that certain legal judgments are entered against Cohu, the insolvency of Cohu, or upon the change of control of Cohu. Any event that could require us to repay debt prior to its due date could have a material adverse impact on our financial condition and results of operations.

Our ability to comply with covenants contained in such debt agreements may be affected by events beyond our control, including prevailing economic, financial and industry conditions. Even if we are able to comply with all of the applicable covenants, the restrictions on our ability to manage our business in our sole discretion could adversely affect our business by, among other things, limiting our ability to take advantage of financings, mergers, acquisitions and other corporate opportunities that we believe would be beneficial to us. In addition, our obligations under the Credit Agreement are secured, on a first-priority basis, and such security interests could be enforced in the event of default by the collateral agent for the Credit Agreement.

Changes in the method of determining the London Interbank Offered Rate (LIBOR), or the replacement of LIBOR with an alternative reference rate, may adversely affect interest rates.

Interest rates under our Credit Agreement are calculated using LIBOR. On July 27, 2017, the Financial Conduct Authority (the authority that regulates LIBOR) announced that it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021 and it is unclear whether new methods of calculating LIBOR will be established. If LIBOR ceases to exist after 2021, a comparable or successor reference rate must be negotiated and agreed among the Administrative Agent, Cohu and certain lenders under the Credit Agreement. The U.S. Federal Reserve, in conjunction with the Alternative Reference Rates Committee, is considering replacing U.S. dollar LIBOR with a newly created index, calculated based on repurchase agreements backed by treasury securities. It is not possible to predict the effect of these changes, other reforms or the establishment of alternative reference rates in the United Kingdom, the United States or elsewhere. To the extent these interest rates increase, our interest expense will increase, which could adversely affect our financial condition, operating results and cash flows.

Cohu has total consolidated debt of $319.9 million as of December 26, 2020 and because of such high debt levels we may not be able to service our debt obligations in accordance with their terms; the Tax Cuts and Jobs Act severely limits the deductibility of interest expense.

Cohu’s ability to meet its expense and debt service obligations contained in the Debt Financing agreements will depend on Cohu’s future performance, which will be affected by financial, business, economic and other factors, including potential changes in industry conditions, industry supply and demand balance, customer preferences, the success of Cohu’s products, pressure from competitors, new product innovation and overall business execution. In addition, Cohu is subject to interest rate risks, and continuing increases in interest rates will increase Cohu’s debt service obligations. If Cohu is ever unable to meet its debt service obligations or fail to comply with the covenants contained in the agreements governing its indebtedness, Cohu may be required to refinance all or part of its debt, sell important strategic assets at unfavorable prices, incur additional indebtedness or issue Cohu Common Stock or other equity securities. Cohu may not be able to, at any given time, refinance its debt, sell assets, incur additional indebtedness or issue equity securities on terms acceptable to Cohu, in amounts sufficient to meet Cohu’s needs or at all. If Cohu is able to raise additional funds through the issuance of equity or equity-linked securities, such issuance would also result in dilution to Cohu’s stockholders. Cohu’s inability to service its debt obligations or refinance its debt could have a material adverse effect on its business, financial conditions or operating results. In addition, Cohu’s debt obligations may limit its ability to make required investments in capacity, technology or other areas of its business, which could have a material adverse effect on its business, financial conditions or operating results. Furthermore, the Tax Cuts and Jobs Act ("Tax Act") limits the deductibility of interest expense in a given year to 30% of adjusted taxable income, as defined; the Coronavirus Aid, Relief, and Economic Security ("CARES") Act temporarily increased this limitation to 50% for 2019 and 2020. This resulted in the inability of Cohu to utilize a substantial portion of its interest expense deductions in 2018 and 2019. We were able to fully deduct the interest expense in 2020 plus the disallowed amounts carried over from 2018 and 2019, however, the Tax Acts may continue to impact our ability to utilize future deductions.

Due to the nature of our business, we need continued access to capital, which if not available to us or if not available on favorable terms, could harm our ability to operate or expand our business.

Our business requires capital to finance accounts receivable and product inventory that is not financed by trade creditors when our business is expanding. If cash from available sources is insufficient or cash is used for unanticipated needs, we may require additional capital sooner than anticipated.

We believe that our existing sources of liquidity, including cash resources and cash provided by operating activities will provide sufficient resources to meet our working capital and cash requirements for at least the next twelve months; however, a material adverse impact from COVID-19 or a desire to reduce our outstanding indebtedness could result in a need to raise additional capital. Alternatively, we could decide to raise capital or incur additional indebtedness to fund strategic initiatives or operating activities, particularly if we pursue additional acquisitions. In the event we are required, or elect, to raise additional funds, we may be unable to do so on favorable terms, or at all, and may incur expenses in raising the additional funds and increase our interest rate exposure, and any future indebtedness could adversely affect our operating results and severely limit our ability to plan for, or react to, changes in our business or industry. Further, under our Credit Agreement, we are significantly limited by financial and other negative covenants in our credit arrangements, including limitations on our borrowing of additional funds and issuing dividends. If we cannot raise funds on acceptable terms, we may not be able to take advantage of future opportunities or respond to competitive pressures or unanticipated requirements. Any inability to raise additional capital when required could have an adverse effect on our business and operating results.

The issuance of shares of our common stock in connection with any future offerings of securities by us, will dilute our shareholders’ ownership interest in the company.

We may seek additional financing in the future to meet our capital needs, to repay outstanding indebtedness under our existing Credit Agreement or to meet our strategic initiatives or operating activities. We have in the past issued common stock as acquisition consideration. For example, the Xcerra acquisition was financed in part by the issuance of additional shares of our common stock to shareholders of Xcerra, comprising approximately 11.8 million shares of common stock, or approximately 29% of our issued and outstanding shares of common stock immediately after completing the transaction. We may determine to utilize common stock as acquisition consideration, issue convertible debt, or pursue a follow-on equity offering to raise capital for debt reduction or for other general corporate purposes, at any time in the future. Any issuances of additional shares of our common stock would dilute shareholders’ ownership interest in our company, and shareholders would have a proportionately reduced ownership and voting interest in our company as a result of equity issuance. If we raise additional funds by issuing debt, we may be subject to limitations on our operations due to restrictive covenants. Additionally, our ability to make scheduled payments or refinance our obligations will depend on our operating and financial performance, which in turn is subject to prevailing economic conditions and financial, business and other factors beyond our control.

Risks Relating to Acquisitions and Other Strategic Transactions

Because a significant portion of Cohu’s total assets are represented by goodwill, which is subject to mandatory impairment evaluation, and other intangibles, Cohu could be required to write off some or all of this goodwill and other intangibles, which may adversely affect the combined company’s financial condition and results of operations.

Cohu accounted for the acquisition of Xcerra using the purchase method of accounting. A portion of the purchase price for this business was allocated to identifiable tangible and intangible assets and assumed liabilities based on estimated fair values at the date of consummation of the merger. 45% of Cohu’s total assets is comprised of goodwill and other intangibles, of which approximately $252.3 million is allocated to goodwill. In accordance with Accounting Standards Codification (“ASC”) 350, Intangibles - Goodwill and Other, goodwill and certain other intangible assets with indefinite useful lives are not amortized but are reviewed at least annually for impairment, or more frequently if there are indications of impairment. Significant declines in the price of Cohu’s common stock could increase the risk of an impairment. All other intangible assets are subject to periodic amortization. Cohu evaluates the remaining useful lives of other intangible assets each quarter to determine whether events and circumstances warrant a revision to the remaining period of amortization. If we are unable to realize the anticipated benefits of the Xcerra acquisition, when Cohu performs future impairment tests, it is possible that the carrying value of goodwill or other intangible assets could exceed their implied fair value and therefore would require adjustment. Such adjustment would result in a charge to operating income in that period. For example, in first quarter 2020, and again in third quarter 2020, Cohu recorded impairment charges of approximately $3.9 million and $7.3 million, respectively, to adjust in-process research and development (“IPR&D”) assets obtained in the acquisition of Xcerra to their current fair value. There can be no assurance that there will not be further adjustments for impairment in future periods.

We are exposed to other risks associated with other acquisitions, investments and divestitures.

As part of our business strategy, we will continue to regularly evaluate investments in, or acquisitions of, complementary businesses, joint ventures, services and technologies, and we expect that periodically we will continue to make such investments and acquisitions in the future. For example, we acquired Xcerra Corporation in 2018 for total consideration of approximately $794.4 million. Acquisitions and investments involve numerous risks, including, but not limited to:

We may decide to finance future acquisitions and investments through a combination of borrowings, proceeds from equity or debt offerings and the use of cash, cash equivalents and short-term investments. If we finance acquisitions or investments by issuing equity-linked (such as convertible debt) or equity securities, our existing stockholders may be diluted which would likely affect the market price of our stock. For example, the Xcerra acquisition resulted in significant dilution as it was financed, in part, by the issuance of approximately 11.8 million shares of common stock, or approximately 29% of our issued and outstanding shares of common stock immediately after completing the transaction. Mergers, acquisitions and investments are inherently risky and the inability to effectively manage these risks could materially and adversely affect our business, financial condition and results of operations.

We expect to continue to evaluate and pursue divestitures of non-core assets

Further, as a strategy to pay down our long-term debt, we expect to continue to evaluate and pursue divestitures of assets that management determines to be non-core to our overall business strategy. Any such divestitures may distract Cohu’s management team, disrupt employees, may not yield attractive valuations, may incur material restructuring and transaction expenses and tax obligations, and may otherwise be unsuccessful. Divestitures may also involve warranties, indemnification or covenants that could restrict our business or result in litigation, additional expenses or liabilities. In addition, discontinuing product categories, even categories that we consider non-strategic, reduces the size and diversification of our business and causes us to be more dependent on a smaller number of product categories.

Risks Relating to Owning Our Stock

Our financial and operating results may vary and fall below analysts’ estimates, or credit rating agencies may change their ratings on Cohu, any of which may cause the price of our common stock to decline or make it difficult to obtain other financing.

Our operating results may fluctuate from quarter to quarter due to a variety of factors including, but not limited to:

Due to these factors or other unanticipated events, quarter-to-quarter comparisons of our operating results may not be reliable indicators of our future performance. In addition, from time-to-time our quarterly financial results may fall below the expectations of the securities and industry analysts who publish reports on our company or of investors in general. This could cause the market price of our stock to decline, perhaps significantly.

In addition, as a result of the Credit Facility, we maintain credit ratings with Moody’s Investors Service, Inc. (“Moody’s”) and S&P Global Ratings (“S&P”). The current Moody’s and S&P issuer credit ratings for Cohu are B2 and B-, respectively. Any future downgrade of Cohu’s credit ratings or rating outlooks may materially and adversely affect the market price of our equity and the availability, cost or interest rate of other credit or financing. Cohu’s current credit ratings are considered non-investment grade and make it more costly (as compared to investment grade borrowers) for Cohu or its subsidiaries to borrow money or enter into new credit facilities and to raise certain other types of capital and/or complete additional financings.

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results, and current and potential stockholders may lose confidence in our financial reporting.

We are required by the Securities and Exchange Commission to establish and maintain adequate internal control over financial reporting that provides reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements in accordance with generally accepted accounting principles. We are likewise required, on a quarterly basis, to evaluate the effectiveness of our internal controls and to disclose any changes and material weaknesses in those internal controls. Although we believe that we have adequate internal controls in place at this time, we cannot be certain that, with significantly greater global complexity, we will be able to maintain adequate internal control over our financial reporting in future periods. Any failure to maintain such internal controls could adversely impact our ability to report our financial results on a timely and accurate basis. If our financial statements are not accurate, investors may not have a complete understanding of our operations. Likewise, if our financial statements are not filed on a timely basis as required by the Securities and Exchange Commission and Nasdaq Global Select Market, we could face severe consequences from those authorities. In either case, there could result a material adverse effect on our business. Inferior internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our stock.

We have experienced significant volatility in our stock price.

A variety of factors may cause the price of our stock to be volatile. The stock market in general, and the market for shares of high-technology companies in particular, including ours, have experienced extreme price fluctuations, which have often been unrelated to the operating performance of affected companies. During the three-year period ended December 26, 2020, the price of our common stock has ranged from $41.00 to $8.89. The price of our stock may be more volatile than the stock of other companies due to, among other factors, the unpredictable, volatile and seasonal nature of the semiconductor industry, our significant customer concentration, intense competition in the test contactor, test handler, automated test equipment and PCB test industry, our limited backlog, our debt levels and high leverage, and our relatively low daily stock trading volume. The market price of our common stock is likely to continue to fluctuate significantly in the future, including fluctuations related and unrelated to our performance.

We may underperform relative to our expectations.

Our business and financial performance are subject to certain risks and uncertainties, as described in these risk factors. We may not achieve our forecasted growth rates, levels of revenue, earnings, or operating efficiency that we expect and may incur losses in the business at any time. Any underperformance from our expectations or forecasts could have a material adverse effect on our financial condition, results of operations, and cause abrupt, significant stock price declines. Also, perceived company underperformance could attract shareholder activism and such activities could interfere with our ability to execute our business plans, be costly and time-consuming, disrupt our operations, divert the attention of management or result in other short-term focused corporate actions, any of which could have an adverse effect on our business or stock price.

Provisions of our certificate of incorporation and bylaws and Delaware law may make a takeover of Cohu more difficult.

There are provisions in our basic corporate documents and under Delaware law that could discourage, delay or prevent a change in control, even if a change in control may be regarded as beneficial to some or all of our stockholders.

Risks Relating to Regulatory Matters

There may be changes in, and uncertainty with respect to, legislation, regulation and governmental policy in the United States.

The change in administration in the United States in January 2021 may result in changes to, and uncertainty with respect to, legislation, regulation and government policy. Specific legislative and regulatory proposals that could have a material impact on us include, but are not limited to, infrastructure renewal programs, modifications to international trade policy, increased duties, tariffs or other export restrictions, public company reporting requirements, environmental regulation, corporate tax legislation, new employment and privacy laws, and antitrust enforcement.

Unanticipated changes in our tax provisions, enactment of new tax laws, or exposure to additional income tax liabilities could affect our profitability.

We are subject to income and other taxes in the U.S. and numerous foreign jurisdictions. Our tax liabilities are affected by, among other things, the amounts our affiliated entities charge each other for intercompany transactions. Our German subsidiaries income tax returns for 2015 to 2017, and our Philippines subsidiary income tax return for 2017 are currently under routine examination by tax authorities in their respective countries. Subsequent to December 26, 2020, we were notified by the taxing authority in Malaysia of its intent to perform an audit for 2014 to 2019 for one of our Malaysian subsidiaries. We may be subject to ongoing tax examinations in various jurisdictions. Tax authorities may disagree with our intercompany charges or other matters and assess additional taxes. While we regularly assess the likely outcomes of these examinations to determine the appropriateness of our tax provision, tax audits are inherently uncertain, and an unfavorable outcome could occur. An unanticipated, unfavorable outcome in any specific period could harm our operating results for that period or future periods. The financial cost and management attention and time devoted to defending income tax positions may divert resources from our business operations, which could harm our business and profitability. Tax examinations may also impact the timing and/or amount of our refund claims. In addition, our effective tax rate in the future could be adversely affected by changes in the mix of earnings in countries with differing statutory tax rates, changes in the valuation of our deferred tax assets and liabilities, changes in tax laws and the discovery of new information in the course of our tax return preparation process. In particular, the carrying value of our deferred tax assets and the utilization of our net operating loss and credit carryforwards are dependent on our ability to generate future taxable income in the U.S. and other countries. Furthermore, these carryforwards may be subject to annual limitations as a result of changes in Cohu’s ownership. As a result of the acquisition of Xcerra, a greater than 50% cumulative ownership change in Xcerra triggered a significant limitation in the utilization of their net operating loss and research credit carryforwards. Cohu’s ability to use the acquired Xcerra U.S. net operating loss and credit carryforwards is subject to annual limitations as defined in sections 382 and 383 of the Internal Revenue Code.

Compliance with regulations may impact sales to foreign customers and impose costs.

Certain products and services that we offer require compliance with U.S. and other foreign country export and other regulations. Compliance with complex U.S. and other foreign country laws and regulations that apply to our international sales activities increases our cost of doing business in international jurisdictions and could expose us or our employees to fines and penalties. These laws and regulations include import and export requirements, the U.S. State Department International Traffic in Arms Regulations (“ITAR”) and U.S. and other foreign country laws such as the Foreign Corrupt Practices Act (“FCPA”), and local laws prohibiting corrupt payments to governmental officials. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers or our employees, prohibitions on the conduct of our business and damage to our reputation. Although we have implemented policies and procedures designed to ensure compliance with these laws, there can be no assurance that our employees, contractors or agents will not violate our policies, or that our policies will be effective in preventing all potential violations. Any such violations could include prohibitions on our ability to offer our products and services to one or more countries, and could also materially damage our reputation, our brand, our international expansion efforts, our ability to attract and retain employees, our business and our operating results. Further, defending against claims of violations of these laws and regulations, even if we are successful, could be time-consuming, result in costly litigation, divert management’s attention and resources and cause us to incur significant expenses.

In addition to government regulations regarding sale and export, we are subject to other regulations regarding our products. For example, the U.S. Securities and Exchange Commission has adopted disclosure rules for companies that use conflict minerals in their products, with substantial supply chain verification requirements if the materials come from, or could have come from, the Democratic Republic of the Congo or adjoining countries. These new rules and verification requirements impose additional costs on us and on our suppliers and may limit the sources or increase the cost of materials used in our products. Further, if we are unable to certify that our products are conflict free, we may face challenges with our customers that could place us at a competitive disadvantage, and our reputation may be harmed.

Global economic and political conditions, including trade tariffs and export restrictions, have impacted our business and may continue to have an impact on our business and financial condition.

In fiscal year 2020, 83% of our revenue was from products shipped to customer locations outside the United States. We also purchase a significant portion of components and subassemblies from suppliers outside the United States. Additionally, a significant portion of our facilities are located outside the United States, including China, Germany, Japan, Malaysia, Philippines, Singapore, Switzerland and Taiwan.

There have been significant changes in U.S. export regulations relating to China since 2019. In May 2019, the Bureau of Industry and Security (“BIS”) of the U.S. Department of Commerce added Huawei to the BIS’s Entity List, which imposes limitations on the supply of certain U.S. items and product support to Huawei (all references to Huawei include its wholly-owned subsidiary HiSilicon). Subsequently, in May 2020 and August 2020, BIS announced rules which amended the foreign-produced direct product rule and the Entity List to target Huawei’s acquisition of Huawei-designed and subsequently third-party semiconductors that are the direct product of certain U.S.-origin software and technology. Also, as of June 2020, the BIS requires exporters to obtain a license for specified items if at the time of the export they had knowledge that the item was intended to support Chinese “military end users,” in addition to “military end uses.”

Cohu has evaluated the foregoing regulations, and at this time, despite an ongoing material adverse impact on direct and indirect Huawei sales, we have not seen any overall material impact to our business. However, we believe that these collective export restrictions and the ongoing unpredictability of U.S.-China trade relations have encouraged China-based companies to actively seek to obtain a greater supply of similar or substitute products from our foreign competitors that are not subject to these restrictions, thereby decreasing our long-term competitiveness as a supplier to China-based companies. Recent history indicates that the U.S. government may impose other new export restrictions, or tariffs, without prior notice impacting our ability (or our customers’ ability) to sell and ship products to China-based companies and any such additional restrictions may have an adverse effect on our business, results of operations, or financial condition. In addition, the change in administration in the United States in January 2021 may result in changes to, and uncertainty with respect to, trade tariffs and export restrictions. Any such changes may have a further adverse effect on our business, results of operations, or financial condition.

Any failure to comply with environmental laws and regulations could subject us to significant fines and liabilities, and new laws and regulations (such as involving climate change) or changes in regulatory interpretation or enforcement could make compliance more difficult and costly.

We are subject to various U.S. federal, state and local, and foreign governmental laws and regulations relating to the protection of the environment, including those governing the discharge of pollutants into the air and water, the management and disposal of hazardous substances and wastes, the cleanup of contaminated sites and the maintenance of a safe workplace. We could incur substantial costs, including cleanup costs, civil or criminal fines or sanctions and third-party claims for property damage or personal injury, as a result of violations of or liabilities under environmental laws and regulations or non-compliance with the environmental permits required at our facilities. In addition, new regulations or public expectations for reductions in greenhouse gas emissions could result in increased energy, transportation and raw material costs, and may require us to make additional investments in facilities and equipment. As a result, the effects of climate change could have a long-term adverse impact on our business and results of operations.

Risks Relating to Cybersecurity, the Economy, and Litigation

Our business and operations could suffer in the event of cybersecurity breaches.

Attempts by others to gain unauthorized access to information technology systems are becoming more sophisticated and are sometimes successful. These attempts, which might be related to industrial or other espionage, include covertly introducing malware to our computers and networks and impersonating authorized users, among others. We seek to detect and investigate all cybersecurity incidents and to prevent their recurrence, but in some cases, we might be unaware of an incident or its magnitude and effects. We have been impacted by immaterial “phishing” schemes and we are continuing our efforts to train employees on such risks but may still incur damages from such schemes in the future. We believe that extensive employee telework practices, implemented in response to the COVID-19 pandemic, have increased our cybersecurity risks. The theft, unauthorized use or publication of our intellectual property and/or confidential business information could harm our competitive position, reduce the value of our investment in research and development and other strategic initiatives or otherwise adversely affect our business. To the extent that any security breach results in inappropriate disclosure of our customers’ or licensees’ confidential information, we may incur liability as a result. Further, in late 2020, a global cyberbreach, widely reported as the “SolarWinds” hack, occurred and caused significant disruption at one of our suppliers and as a result created delays in our operation. Any future attacks that disrupt our IT systems, or those of our suppliers, could impact our sales, financial results and stock price. In response to these risks, we expect to continue to devote additional resources to the security of our information technology systems.

The occurrence of natural disasters, health epidemics, and geopolitical instability caused by terrorist attacks and other threats may adversely impact our operations and sales.

Our corporate headquarters is located in San Diego, California, our Asian sales and service headquarters are located in Singapore and Taiwan, and the majority of our sales are made to destinations in Asia. In addition, we have Asia-based manufacturing plants in Malaysia, Philippines and Japan. These regions are known for being vulnerable to natural disasters and other risks, such as earthquakes, tsunamis, fires and floods, volcanic eruptions, and geopolitical risks, which at times have disrupted the local economies. For example, a significant earthquake or tsunami could materially affect operating results. We are not insured for most losses and business interruptions of this kind, or for geopolitical or terrorism impacts, and presently have limited redundant, multiple site capacity in the event of a disaster. In the event of such disaster, our business would materially suffer.

Our business could also be adversely affected by the effects of a widespread outbreak of contagious diseases, and has been and is continuing to be adversely affected by the COVID-19 global pandemic (see risk factor entitled “The ongoing global COVID-19 pandemic has adversely affected, and is continuing to adversely affect, our business, financial condition and results of operations”).

Global economic conditions may have an impact on our business and financial condition in ways that we currently cannot predict.

Our operations and financial results depend on worldwide economic conditions and their impact on levels of business spending. Continued uncertainties may reduce future sales of our products and services. While we believe we have a strong customer base and have experienced strong collections in the past, if the current market conditions deteriorate, we may experience increased collection times and greater write-offs, either of which could have a material adverse effect on our cash flow.

In addition, the tightening of credit markets and concerns regarding the availability of credit may make it more difficult for our customers to raise capital, whether debt or equity, to finance their purchases of capital equipment, including the products we sell. Delays in our customers’ ability to obtain such financing, or the unavailability of such financing would adversely affect our product sales and revenues and therefore harm our business and operating results. Possible import, export, tariff and other trade barriers, which could be imposed by Asia, the United States, other countries or the European Union might also have a material adverse effect on our operating results. We cannot predict the timing, duration of or effect on our business of an economic slowdown or the timing or strength of a subsequent recovery.

We may become subject to litigation or regulatory proceedings that could have an adverse effect on our business.

From time to time, we may be subject to litigation or other administrative, regulatory or governmental proceedings, including tax audits and resulting claims that could require significant management time and resources and cause us to incur expenses and, in the event of an adverse decision, pay damages or incur costs in an amount that could have a material adverse effect on our financial position or results of operations.

The information required by this Item regarding equity compensation plans is incorporated by reference to the information set forth in Part III, Item 12 of this Annual Report on Form 10-K.

Comparative Stock Performance Graph

The information contained in this Stock Performance Graph section shall not be deemed to be “soliciting material” or “filed” with the SEC or subject to the liabilities of Section 18 of the Exchange Act except to the extent that Cohu specifically incorporates it by reference into a document filed under the Securities Act or the Exchange Act.

The graph below compares the cumulative total stockholder return on the common stock of Cohu for the last five fiscal years with the cumulative total return on custom Peer Group Indexes and a Nasdaq Global Select Market Index over the same period (assuming the investment of $100 in Cohu’s common stock, Peer Group Index and Nasdaq Global Select Market Index on December 26, 2015, and reinvestment of all dividends). The custom Peer Group Index is comprised of the peer group companies associated with our performance stock units issued under our equity incentive plan. This peer group is revised annually to reflect acquisitions and to include equivalent companies in the semiconductor equipment market to ensure a sufficiently large number of companies in the peer group composition to enable a meaningful comparison of our stock performance. In 2020, the custom Peer Group Index was comprised of Advanced Energy Industries Inc., Axcelis Technologies Inc., Brooks Automation Inc., Cabot Microelectronics Corp, Cirrus Logic Inc., Entegris, Inc., FormFactor Inc., Kulicke and Soffa Industries Inc., MTS Systems Corporation, Novanta Inc, OSI Systems, Inc., Onto Innovation Inc. (formerly Nanometrics Inc.), Photronics Inc., Synaptics, Ultra Clean Holdings Inc., and Veeco Instruments Inc. In 2019, the custom Peer Group Index was comprised of Advanced Energy Industries Inc., Advantest Corp, ASM Pacific Technology Ltd, Axcelis Technologies Inc., BE Semiconductor Industries NV, Brooks Automation Inc., Cabot Microelectronics Corp, Camtek Ltd, Electro Scientific Industries Inc., FormFactor Inc., Kulicke and Soffa Industries Inc., Micronics Japan Co Ltd, MKS Instruments Inc., Nanometrics Inc., Photronics Inc., Rudolph Technologies Inc., Teradyne Inc., Ultra Clean Holdings Inc., and Veeco Instruments Inc. (includes Ultratech through acquisition). In selecting our 2020 peer group the Compensation Committee of our Board of Directors considered competitive market data and an analysis prepared by Compensia and identified companies headquartered in the U.S. in the semiconductor capital equipment and electronic capital equipment and instrumentation sectors that were comparable to us on the basis of revenue, our market capitalization, and that had similar scope of operations.

Item 6. Selected Financial Data.

The following selected financial data should be read in conjunction with Cohu’s consolidated financial statements and notes thereto included in Part IV, Item 15(a) and with management’s discussion and analysis of financial condition and results of operations, included in Part II, Item 7. On October 1, 2018, we completed the acquisition of Xcerra Corporation and the results of its operations have been included in our consolidated financial statements only since that date. Due to the timing of the acquisition our results for 2018 only include Xcerra for the three months ended December 29, 2018. Results for the periods ended December 26, 2020 and December 28, 2019 include Xcerra for the full twelve months. Management determined that the fixtures services business, that was acquired as part of Xcerra, did not align with Cohu’s long-term strategic plan and management divested this portion of the business in February 2020. As a result, the assets of our fixtures business are considered “held for sale” as of December 28, 2019 and December 29, 2018 and the operations of our fixtures business are reported as “discontinued operations” for the periods ended December 26, 2020, December 28, 2019 and December 29, 2018.

In 2019, total operating expenses related to the acquisition of Xcerra were as follows: $16.2 million in restructuring charges comprised of $2.7 million of inventory end-of-manufacturing write-downs recorded in cost of sales related to Xcerra’s products, employee severance costs of $12.2 million and $1.3 million of other restructuring costs. We also recorded $35.5 million for the amortization of acquisition-related intangibles and $0.4 million of merger related costs.

In 2018, total operating expenses related to the acquisition of Xcerra as follows: $37.8 million in restructuring charges comprised of $19.1 million of inventory end-of-manufacturing write-downs recorded in cost of sales related to Xcerra’s products, employee severance costs of $17.8 million and $0.9 million of other restructuring costs. We also recorded $13.1 million for the amortization of acquisition-related intangibles and $9.8 million of merger related costs.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

OVERVIEW 

Cohu is a leading supplier of semiconductor test and inspection handlers, micro-electromechanical system (MEMS) test modules, test contactors and thermal subsystems, semiconductor automated test equipment and bare board printed circuit board (PCB) test systems used by global semiconductor and electronics manufacturers and test subcontractors. We offer a wide range of products and services and our revenue from capital equipment products is driven by the capital expenditure budgets and spending patterns of our customers, who often abruptly delay or accelerate purchases in reaction to variations in their business. The level of capital expenditures by these companies depends on the current and anticipated market demand for semiconductor devices and printed circuit boards and the products that incorporate them. Our consumable products are driven by the number of semiconductor devices and printed circuit boards that are tested and by the continuous introduction of new products and new technologies by our customers. As a result, our consumable products provide a more stable recurring source of revenue and generally do not have the same degree of cyclicality as our capital equipment products.

For the year ended December 26, 2020, our net sales increased 9.0% year-over-year to $636.0 million. Our consolidated net sales for the years ended December 26, 2020 and December 28, 2019, include Xcerra’s sales for the full year (all twelve months) totaling $331.2 million and $300.8 million, respectively. The year ended December 29, 2018, includes Xcerra’s sales for the three months subsequent to the merger on October 1, 2018, which totaled $94.4 million.

In 2019 and 2020, the global semiconductor market was impacted by U.S. and China trade tensions which impacted our customers’ ability to supply product to certain end users resulting in customer test cell utilization below levels that have historically triggered the need for additional capacity. During the first half of 2020 our net sales were negatively impacted by movement control orders and the subsequent supply disruptions caused by the rapid and global spread of COVID-19 and weakness in the automotive market. Demand for equipment used in testing mobility semiconductor applications, data centers and personal computers strengthened during the second half of 2020 driven by the launch and accelerated ramp of our RedDragon RF module for testing 5G, Wi-Fi 6 and Ultra-Wideband devices, and new customers for our Neon inspection platform. We also began to see improved demand from semiconductor automotive and industrial customers and orders for PCB test equipment were at near record levels. Based on improved business conditions, during the second half of 2020, we took action to reduce outstanding principal, by $36.4 million, under our Term Loan B debt associated with the financing of the Xcerra acquisition in October 2018.

While our total sales for the twelve months of 2020 were negatively impacted by the global economic downturn caused by the COVID-19 pandemic, we saw strong demand for our products in the second half of the year and our long-term market drivers and market strategy remain intact. We are encouraged by positive order momentum across our main market segments, and customer traction with our new products going into 2021. We remain optimistic about the long-term prospects for our business due to the increasing ubiquity of semiconductors, the future rollout of 5G networks, increasing semiconductor complexity, increasing quality demands from semiconductor customers, increasing test intensity and continued proliferation of electronics in a variety of products across the automotive, mobility and industrial markets. We are focused on cross-selling opportunities and supporting our customers’ deployment of 5G RF capabilities on next generation smartphones and growing our sales to semiconductor and electronics manufacturers and test subcontractors.

Application of Critical Accounting Estimates and Policies

Our discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We base our estimates on historical experience, forecasts and on various other assumptions that are believed to be reasonable under the circumstances; however actual results may differ from those estimates under different assumptions or conditions. The methods, estimates and judgments we use in applying our accounting policies have a significant impact on the results we report in our financial statements. Some of our accounting policies require us to make difficult and subjective judgments, often as a result of the need to make estimates of matters that are inherently uncertain. Our critical accounting estimates that we believe are the most important to investors’ understanding of our financial results and condition and require complex management judgment include:

Below, we discuss these policies further, as well as the estimates and judgments involved. We also have other policies that we consider key accounting policies; however, these policies typically do not require us to make estimates or judgments that are difficult or subjective.

Revenue Recognition: Our net sales are derived from the sale of products and services and are adjusted for estimated returns and allowances, which historically have been insignificant. We recognize revenue when the obligations under the terms of a contract with our customers are satisfied; generally, this occurs with the transfer of control of our systems, non-system products or services. In circumstances where control is not transferred until destination or acceptance, we defer revenue recognition until such events occur. Revenue for established products that have previously satisfied a customer’s acceptance requirements is generally recognized upon shipment. In cases where a prior history of customer acceptance cannot be demonstrated or from sales where customer payment dates are not determinable and in the case of new products, revenue and cost of sales are deferred until customer acceptance has been received. Our post-shipment obligations typically include installation and standard warranties. The estimated fair value of installation related revenue is recognized in the period the installation is performed. Service revenue is recognized over time as the transfer of control is completed for the related contract or upon completion of the services if they are short-term in nature. Spares, contactor and kit revenue is generally recognized upon shipment. Certain of our equipment sales have multiple performance obligations. These arrangements involve the delivery or performance of multiple performance obligations, and transfer of control of performance obligations may occur at different points in time or over different periods of time. For arrangements containing multiple performance obligations, the revenue relating to the undelivered performance obligation is deferred using the relative standalone selling price method utilizing estimated sales prices until satisfaction of the deferred performance obligation. Unsatisfied performance obligations primarily represent contracts for products with future delivery dates. At December 26, 2020 and December 28, 2019 we had $17.1 million and $16.1 million of revenue expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied), respectively. We generally sell our equipment with a product warranty. The product warranty provides assurance to customers that delivered products are as specified in the contract (an “assurance-type warranty”). Therefore, we account for such product warranties under ASC 460, Guarantees (“ASC 460”), and not as a separate performance obligation. The transaction price reflects our expectations about the consideration we will be entitled to receive from the customer and may include fixed or variable amounts. Fixed consideration primarily includes sales to customers that are known as of the end of the reporting period. Variable consideration includes sales in which the amount of consideration that we will receive is unknown as of the end of a reporting period. Such consideration primarily includes sales made to certain customers with cumulative tier volume discounts offered. Variable consideration arrangements are rare; however, when they occur, we estimate variable consideration as the expected value to which we expect to be entitled. Included in the transaction price estimate are amounts in which it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The estimate is based on information available for projected future sales. Variable consideration that does not meet revenue recognition criteria is deferred. Accounts receivable represents our unconditional right to receive consideration from our customer. Payments terms do not exceed one year from the invoice date and therefore do not include a significant financing component. To date, there have been no material impairment losses on accounts receivable. There were no material contract assets recorded on the consolidated balance sheet in any of the periods presented. On shipments where sales are not recognized, gross profit is generally recorded as deferred profit in our consolidated balance sheet representing the difference between the receivable recorded and the inventory shipped.

Accounts Receivable: We maintain an allowance for credit losses for estimated losses resulting from the inability of our customers to make required payments. If the financial condition of our customers deteriorates, resulting in an impairment of their ability to make payments, additional allowances may be required. Our customers include semiconductor manufacturers and semiconductor test subcontractors throughout many areas of the world. While we believe that our allowance for credit losses is adequate and represents our best estimate of future losses we will continue to monitor customer liquidity and other economic conditions, including the impact of the COVID-19 pandemic, which may result in changes to our estimates.

We adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, on December 29, 2019 the first day of our fiscal 2020. The ASU required a cumulative-effect adjustment to the statement of financial position as of the date of adoption. Periods prior to the adoption that are presented for comparative purposes are not adjusted. Based on our analysis of historical and anticipated collections of trade receivables, the impact of adoption of Topic 326 was insignificant.

Inventory: The valuation of inventory requires us to estimate obsolete or excess inventory as well as inventory that is not of saleable quality. The determination of obsolete or excess inventory requires us to estimate the future demand for our products. The demand forecast is a direct input in the development of our short-term manufacturing plans. We record valuation reserves on our inventory for estimated excess and obsolete inventory and lower of cost or net realizable value concerns equal to the difference between the cost of inventory and the estimated realizable value based upon assumptions about future product demand, market conditions and product selling prices. If future product demand, market conditions or product selling prices are less than those projected by management or if continued modifications to products are required to meet specifications or other customer requirements, increases to inventory reserves may be required which would have a negative impact on our gross margin.

Income Taxes: We estimate our liability for income taxes based on the various jurisdictions where we conduct business. This requires us to estimate our (i) current taxes; (ii) temporary differences that result from differing treatment of certain items for tax and accounting purposes and (iii) unrecognized tax benefits. Temporary differences result in deferred tax assets and liabilities that are reflected in the consolidated balance sheet. The deferred tax assets are reduced by a valuation allowance if, based upon all available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. Establishing, reducing or increasing a valuation allowance in an accounting period generally results in an increase or decrease in tax expense in the statement of operations. We must make significant judgments to determine the provision for income taxes, deferred tax assets and liabilities, unrecognized tax benefits and any valuation allowance to be recorded against deferred tax assets. Our gross deferred tax asset balance as of December 26, 2020, was approximately $122.8 million, with a valuation allowance of approximately $86.1 million.

The Tax Act was enacted on December 22, 2017. The accounting for the tax effects of the enactment of the Tax Act was completed in 2018. The accounting for the CARES Act, enacted on March 27, 2020, was incorporated in 2020. See Note 9, “Income Taxes”, included in Part IV, Item 15(a) of this Form 10-K, which is incorporated herein by reference.

Segment Information: We applied the provisions of ASC Topic 280, Segment Reporting, (“ASC 280”), which sets forth a management approach to segment reporting and establishes requirements to report selected segment information quarterly and to report annually entity-wide disclosures about products, major customers and the geographies in which the entity holds material assets and reports revenue. An operating segment is defined as a component that engages in business activities whose operating results are reviewed by the chief operating decision maker and for which discrete financial information is available. We have determined that our four identified operating segments are: Test Handler Group (“THG”), Semiconductor Tester Group (“STG”), Interface Solutions Group (“ISG”) and PCB Test Group (“PTG”). Our THG, STG and ISG operating segments qualify for aggregation under ASC 280 due to similarities in their customers, their economic characteristics, and the nature of products and services provided. As a result, we report in two segments, Semiconductor Test & Inspection and PCB Test.

Goodwill and Indefinite-Lived Intangibles, Other Intangible Assets and Long-lived Assets: We evaluate goodwill and other indefinite-lived intangible assets, which are solely comprised of in-process research and development (“IPR&D”), for impairment annually and when an event occurs or circumstances change that indicate that the carrying value may not be recoverable. We test goodwill for impairment by first comparing the book value of net assets to the fair value of the reporting unit or asset, in the case of in-process research and development. If the fair value is determined to be less than the book value, a second step is performed to compute the amount of impairment as the difference between the fair value of the reporting unit and it’s carrying value of goodwill. We estimated the fair values of our reporting units primarily using the income approach valuation methodology that includes the discounted cash flow method, taking into consideration the market approach and certain market multiples as a validation of the values derived using the discounted cash flow methodology. Forecasts of future cash flows are based on our best estimate of future net sales and operating expenses, based primarily on customer forecasts, industry trade organization data and general economic conditions. Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions and factors.

We conduct our annual impairment test as of October 1st of each year, and have determined there was no impairment as of October 1, 2020, as we determined that the estimated fair values of our reporting units exceeded their carrying values on that date. Other events and changes in circumstances may also require goodwill to be tested for impairment between annual measurement dates. As of December 26, 2020, we do not believe that circumstances have occurred that indicate impairment of our goodwill is more-likely-than-not. In the event we determine that an interim goodwill impairment review is required in a future period, the review may result in an impairment charge, which would have a negative impact on our results of operations.

During the first quarter of 2020, the volatility in Cohu’s stock price, the global economic downturn and business interruptions associated with the COVID-19 pandemic led us to determine that there was a triggering event related to goodwill within all of our identified reporting units and our indefinite-lived intangible assets. We performed an interim assessment as of March 28, 2020 and determined that the fair values of our identified reporting units all exceeded their carrying values and we concluded there was no impairment of goodwill within our reporting units. Anticipated delays in customer adoption of certain new products under development as a result of the COVID-19 pandemic, changes to future project roadmaps and an increase in the discount rate used in the developing our interim fair value estimate resulted in a $3.9 million impairment to IPR&D recorded during the first quarter as the carrying value exceeded fair value. During the third quarter of 2020, we became aware of additional delays in customer adoption of the same new products under development leading us to re-evaluate the fair value of these projects and we determined that the carrying value exceeded the fair value and, as a result, we recorded a $7.3 million impairment to IPR&D. For the twelve months ended December 26, 2020 total impairments recorded to IPR&D projects was $11.2 million.

The forecasts utilized in the interim impairment tests were based on known facts and circumstances. We evaluate and consider recent events and uncertain items, as well as related potential implications, as part of our annual and interim assessments and incorporate them into the analyses as appropriate. These facts and circumstances are subject to change and may not be the same as future analyses. In a future period, should we again determine that an interim goodwill and indefinite-lived intangible asset impairment review is required we may be required to book additional impairment charges which could have a significant negative impact on our results of operations.

Long-lived assets, other than goodwill, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets might not be recoverable. Conditions that would necessitate an impairment assessment include a significant decline in the observable market value of an asset, a significant change in the extent or manner in which an asset is used, or any other significant adverse change that would indicate that the carrying amount of an asset or group of assets may not be recoverable. For long-lived assets, impairment losses are only recorded if the asset’s carrying amount is not recoverable through its undiscounted, probability-weighted future cash flows. We measure the impairment loss based on the difference between the carrying amount and estimated fair value.

Warranty: We provide for the estimated costs of product warranties in the period sales are recognized. Our warranty obligation estimates are affected by historical product shipment levels, product performance and material and labor costs incurred in correcting product performance problems. Should product performance, material usage or labor repair costs differ from our estimates, revisions to the estimated warranty liability would be required.

Contingencies: We are subject to certain contingencies that arise in the ordinary course of our businesses which require us to assess the likelihood that future events will confirm the existence of a loss or an impairment of an asset. If a loss or asset impairment is probable and the amount of the loss or impairment is reasonably estimable, we accrue a charge to operations in the period such conditions become known.

Share-based Compensation: Share-based compensation expense related to restricted stock unit awards is calculated based on the market price of our common stock on the grant date, reduced by the present value of dividends expected to be paid on our common stock prior to vesting of the restricted stock unit. Share-based compensation on performance stock units with market-based goals is calculated using a Monte Carlo simulation model on the date of the grant. Share-based compensation expense related to stock options is recorded based on the fair value of the award on its grant date, which we estimate using the Black-Scholes valuation model.

Our estimate of share-based compensation expense requires a number of complex and subjective assumptions and the assumptions used in calculating the fair value of share-based awards represent our best estimates, but these estimates involve inherent uncertainties and the application of management judgment. Although we believe the assumptions and estimates we have made are reasonable and appropriate, changes in assumptions could materially impact our reported financial results.

Recent Accounting Pronouncements: For a description of accounting changes and recent accounting pronouncements, including the expected dates of adoption and estimated effects, if any, on our consolidated financial statements, see Note 1, “Recent Accounting Pronouncements” in Part IV, Item 15(a) of this Form 10-K.

RESULTS OF OPERATIONS

Recent Transactions Impacting Results of Operations

On October 1, 2018 we completed our merger with Xcerra Corporation and the results of its operations have been included in our consolidated financial statements only since that date. Due to the timing of the merger our results for 2018 only include Xcerra for the three months ended December 29, 2018 whereas the periods ended December 26, 2020 and December 28, 2019 include Xcerra for the full twelve months. Previously, management determined that the fixtures services business, that was acquired as part of Xcerra, did not align with Cohu’s long-term strategic plan and management divested this portion of the business in February 2020. The assets of our fixtures business were considered “held for sale” as of December 28, 2019 and the operating results of our fixtures business are presented as “discontinued operations” for the periods ended December 26, 2020, December 28, 2019 and December 29, 2018. Unless otherwise indicated, the discussion below covers the comparative results from continuing operations.

The following table summarizes certain operating data as a percentage of net sales:

Please refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 in our 2019 Annual Report on Form 10-K, filed with the SEC on March 10, 2020, for comparative discussion of our fiscal years ended December 28, 2019 and December 29, 2018.

2020 Compared to 2019

Net Sales

Cohu’s consolidated net sales increased 9.0% from $583.3 million in 2019 to $636.0 million in 2020. During the first half of 2020, our net sales were impacted by disruptions caused by the COVID-19 pandemic and movement control orders which resulted in supply disruptions impacting our ability to ship product and were further impacted by reduced demand in the automotive segment. In the second half of 2020 demand for equipment used in testing mobility semiconductor applications, data centers and personal computers strengthened driven by the launch and accelerated ramp of our RedDragon RF module for testing 5G, Wi-Fi 6 and Ultra-Wideband devices, and new customers for our Neon inspection platform. We also began to see improved demand from semiconductor automotive and industrial customers, and orders for PCB test equipment were at near record levels.

Gross Margin (exclusive of amortization of acquisition-related intangible assets described below)

Gross margin consists of net sales less cost of sales (excluding the impact of amortization of developed technology and backlog). Cost of sales consists primarily of the materials, assembly and test labor and overhead from operations. Our gross margin can fluctuate due to a number of factors, including, but not limited to, the mix of products sold, product support costs, increases to inventory reserves, the sale of previously reserved inventory and utilization of manufacturing capacity. Our gross margin, as a percentage of net sales, increased to 42.7% in 2020 from 39.4% in 2019. Increased business volume in the second half of 2020 allowed us to better leverage our fixed costs helping to improve our gross margin over 2019. Other items impacting our gross margin in 2020 are discussed below.

We compute the majority of our excess and obsolete inventory reserve requirements using inventory usage forecasts ranging from one to three years. During 2020, we recorded net charges to cost of sales of approximately $6.0 million, for excess and obsolete inventory. In addition to our normal excess and obsolete provision, as part of the integration and restructuring activities related to Xcerra we recorded $3.7 million of inventory related charges specifically related to the decision to end manufacturing of certain semiconductor test handler products. In 2019, net charges to cost of sales were $4.1 million, for excess and obsolete inventory and we recorded $2.7 million of inventory related charges related to the decision to end manufacturing of certain of Xcerra’s semiconductor test handler products.

We believe our reserves for excess and obsolete inventory and lower of cost or net realizable value are adequate to cover known exposures at December 26, 2020. Reductions in customer forecasts, continued modifications to products, our failure to meet specifications or other customer requirements may result in additional charges to operations that could negatively impact our gross margin in future periods.

Our cost of sales was also impacted by the amortization of inventory step-up related to fair value adjustments to inventory acquired from Xcerra and during 2019, $6.0 million of inventory step-up costs were amortized. All inventory step-up was fully amortized in in 2019 and there was no amortization in 2020.

Research and Development Expense (“R&D Expense”)

R&D expense consists primarily of salaries and related costs of employees engaged in ongoing research, product design and development activities, costs of engineering materials and supplies and professional consulting expenses. Our future operating results depend, to a considerable extent, on our ability to maintain a competitive advantage in the products we provide, and historically we have maintained our commitment to investing in R&D in order to be able to continue to offer new products to our customers. R&D expense in 2020 was $86.2 million, or 13.5% of net sales, compared to $86.1 million, or 14.8% of net sales in 2019. Despite increased business volume, R&D expense was essentially flat, year-over-year, as temporary salary reductions, decreased travel and other cost control measures implemented in response to the economic uncertainty caused by the COVID-19 pandemic allowed us to control costs in 2020.

Selling, General and Administrative Expense (“SG&A Expense”)

SG&A expense consists primarily of salaries and benefit costs of employees, commission expense for independent sales representatives, product promotion and costs of professional services. SG&A expense as a percentage of net sales decreased to 20.3% in 2020, from 24.5% in 2019, decreasing from $142.9 million in 2019 to $129.2 million in 2020. Lower SG&A expense in 2020 was a result of temporary salary reductions, decreased travel and other cost control measures implemented in response to the economic uncertainty caused by the COVID-19 pandemic.

From time-to-time Cohu incurs costs specifically related to business acquisitions. In 2019, we incurred acquisition costs totaling $0.4 million that were entirely comprised of professional service and other transaction related expenses associated with the merger of Xcerra. No acquisition costs were incurred in 2020.

In 2020 and 2019, we recorded $0.1 million and $1.2 million of expense, respectively, related to a reduction of an indemnification receivable related to an uncertain tax position recorded in the acquisition of Ismeca Semiconductor Holdings SA (“Ismeca”) in 2013. In connection with this reduction we also booked a corresponding amount as a credit to our income tax provision and, as a result, the impact of this reduction on net income was zero.

Amortization of Purchased Intangible Assets

Amortization of purchased intangibles is the process of expensing the cost of an intangible asset acquired through a business combination over the projected life of the asset. Amortization of acquisition-related intangible assets was $38.7 million and $39.6 million for 2020 and 2019, respectively. The decrease in expense recorded during the current year was a result of fluctuations in exchange rates.

Restructuring Charges

Subsequent to the merger with Xcerra in the fourth quarter 2018, we began a strategic restructuring program designed to reposition our organization and improve our cost structure as part of our targeted integration plan regarding Xcerra. In connection with the integration plan, we recorded restructuring charges, exclusive of the inventory related charges described above, totaling $7.6 million and $13.5 million in 2020 and 2019, respectively.

See Note 5, “Restructuring Charges” in Part IV, Item 15(a) of this Form 10-K for additional information with respect to restructuring charges.

Impairment Charges

During the first quarter of 2020, the volatility in Cohu’s stock price and the global economic downturn and business interruptions associated with the COVID-19 pandemic led us to determine that there was a triggering event related to goodwill within all of our identified reporting units and our indefinite-lived intangible assets. We performed an interim assessment as of March 28, 2020 and determined that the fair values of our identified reporting units all exceeded their carrying values and concluded there was no impairment of goodwill within our reporting units. Anticipated delays in customer adoption of certain new products under development as a result of the COVID-19 pandemic, changes to future project roadmap and an increase in the discount rate used in developing our interim fair value estimate resulted in a $3.9 million impairment to IPR&D as the carrying value exceeded fair value. During the third quarter of 2020, we became aware of additional delays in customer adoption of certain new products under development as a result of the COVID-19 pandemic and customer product road map changes. This change in facts led us to re-evaluate the fair value of these projects and we determined that the carrying value exceeded the fair value, and we recorded an additional $7.3 million impairment to IPR&D. For the twelve months ended December 26, 2020, total impairments recorded to IPR&D projects was $11.2 million.

Gain on sale of facilities

As part of our previously announced Xcerra integration plan we implemented certain facility consolidation actions. During 2020 we completed the sales of our facilities located in Rosenheim, Germany and Penang, Malaysia resulting in a gain of $4.5 million.

Interest Expense and Income

Interest expense was $13.8 million in 2020 compared to $20.6 million in 2019. The year-over-year decrease in our interest expense resulted from a significant decrease in LIBOR and the reduction in the outstanding principal under our Term Loan B debt associated with the financing of the Xcerra acquisition.

Interest income was $0.2 million in 2020 as compared to $0.8 million in 2019.

Foreign Transaction Gain (Loss) and Other

We have operations in foreign countries and conduct business in the local currency in these countries. During 2020, the U.S. Dollar weakened significantly against the Swiss Franc and Euro, which resulted in the recognition of $3.2 million in foreign currency losses, net of $0.8 million of gains generated by foreign currency forward contracts. During the fourth quarter of 2020, we began entering into foreign currency forward contracts to hedge against future movements in foreign exchange rates that affect certain U.S. Dollar denominated assets and liabilities at our subsidiaries whose functional currency is the local currency. In 2019, we incurred an insignificant foreign currency transaction gain for the year.

See Note 8 “Derivative Financial Instruments” in Part IV, Item 15(a) of this Form 10-K for additional information with respect to our foreign currency forward contracts.

Income Taxes

The income tax provision (benefit) expressed as a percentage of pre-tax income or loss in 2020 and 2019 was 5.1% and (4.3)%, respectively. The income tax provision (benefit) for the years ended December 26, 2020, and December 28, 2019 differs from the U.S. federal statutory rate primarily due to changes in the valuation allowance on our deferred tax assets, foreign income taxed at different rates, releases from statute expirations, impact of the Tax Act and other factors.

Companies are required to assess whether a valuation allowance should be recorded against their deferred tax assets (“DTAs”) based on the consideration of all available evidence, using a “more likely than not” realization standard. The four sources of taxable income that must be considered in determining whether DTAs will be realized are, (1) future reversals of existing taxable temporary differences (i.e. offset of gross deferred tax assets against gross deferred tax liabilities); (2) taxable income in prior carryback years, if carryback is permitted under the tax law; (3) tax planning strategies and (4) future taxable income exclusive of reversing temporary differences and carryforwards.

In assessing whether a valuation allowance is required, significant weight is to be given to evidence that can be objectively verified. We have evaluated our DTAs at each reporting period, including an assessment of our cumulative income or loss over the prior three-year period and future periods, to determine if a valuation allowance was required. A significant negative factor in our assessment was Cohu’s three-year cumulative loss history at the end of various fiscal periods including 2020.

As a result of our cumulative, three-year U.S. GAAP pretax loss from continuing operations at the end of 2020, we were unable to conclude that it was “more likely than not” that our U.S. DTAs would be realized. We will evaluate the realizability of our DTAs at the end of each quarterly reporting period in 2021 and, should circumstances change, it is possible an additional valuation allowance will be recorded or the remaining valuation allowance, or a portion thereof, will be reversed in a future period.

Our valuation allowance on our DTAs at December 26, 2020, and December 28, 2019, was approximately $86.1 million and $93.5 million, respectively. The remaining gross DTAs for which a valuation allowance was not recorded are realizable primarily through future reversals of existing taxable temporary differences and to a lesser extent future taxable income exclusive of reversing temporary differences and carryforwards.

As the realization of DTAs is determined by tax jurisdiction, the deferred tax liabilities recorded by our non-U.S. subsidiaries were not a source of taxable income in assessing the realization of our DTAs in the U.S.

For a full reconciliation of our effective tax rate to the U.S. federal statutory rate and further explanation of our provision for income taxes, see Note 9, “Income Taxes”, included in Part IV, Item 15(a) of this Form 10-K, which is incorporated herein by reference.

Loss from Continuing Operations and Net Loss

As a result of the factors set forth above, our net loss from continuing operations and net loss was $13.8 million in 2020. Net loss from continuing operations was $69.0 million in 2019 and, including the results of our discontinued operations which includes an impairment related to the disposal of our FSG segment, our net loss was $69.7 million.

LIQUIDITY AND CAPITAL RESOURCES

Our business is dependent on capital expenditures by semiconductor manufacturers and test subcontractors that are, in turn, dependent on the current and anticipated market demand for semiconductors. The seasonal and volatile nature of demand for semiconductor equipment, our primary industry, makes estimates of future revenues, results of operations and net cash flows difficult.

Our primary historical source of liquidity and capital resources has been cash flow generated by operations and we manage our business to maximize operating cash flows as our primary source of liquidity. We use cash to fund growth in our operating assets and to fund new products and product enhancements primarily through research and development.

On October 1, 2018, we entered into a bank credit agreement which provides for a $350.0 million seven-year Term Loan B facility and borrowed the full amount. The Term Loan B facility matures on October 1, 2025. These proceeds were used on October 1, 2018, together with our cash and cash equivalents, to finance the acquisition of Xcerra. See Note 4 “Borrowings and Credit Agreements” included in Part IV, Item 15(a) of this Form 10-K, which is incorporated herein by reference.

At December 26, 2020, our total indebtedness, net of discount and deferred financing costs, was $319.9 million, which included $301.1 million outstanding under the Term Loan B, $3.6 million outstanding under Kita’s term loans, $9.9 million outstanding under Cohu GmbH’s construction loans, and $5.3 million outstanding under Kita’s lines of credit.

We believe that our sources of liquidity will be sufficient to satisfy our anticipated cash requirements through at least the next 12 months. Our liquidity could be negatively affected by a decrease in demand for our products. In addition, we may make acquisitions or increase our capital expenditures and may need to raise additional capital through debt or equity financing to provide for greater flexibility to fund these activities. Additional financing may not be available or not available on terms favorable to us. A discussion of cash flows for the year ended December 29, 2018 has been omitted from this Annual Report on Form 10-K, but may be found in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations,” under the heading “Liquidity and Capital Resources” in our Annual Report on Form 10-K for the year ended December 28, 2019, filed with the SEC on March 10, 2020, which discussion is incorporated herein by reference and which is available free of charge on the SEC’s website at www.sec.gov.

Liquidity

Working Capital: The following summarizes our cash, cash equivalents, short-term investments and working capital at December 26, 2020 and December 28, 2019:

As of December 26, 2020, $74.4 million of our cash, cash equivalents and short-term investments was held by our foreign subsidiaries. If these funds are needed for our operations in the U.S., we may be required to accrue and pay foreign withholding taxes if we repatriate these funds. Except for working capital requirements in certain jurisdictions, we provide for all withholding and other residual taxes related to unremitted earnings of our foreign subsidiaries. Beginning in 2018, earnings realized in foreign jurisdictions are subject to U.S. taxes in accordance with the Tax Act.

Cash Flows

Operating Activities: Cash provided by operating activities consists of our net loss adjusted for non-cash expenses and changes in operating assets and liabilities. These adjustments include impairment charges, depreciation expense on property, plant and equipment, share-based compensation expense, amortization of intangible assets, deferred income taxes, amortization of cloud-based software implementation costs, gain on extinguishment of debt, interest capitalized associated with cloud computing implementation, amortization of debt discounts and issuance costs and gains from sale of property, plant and equipment. Our net cash flows provided by operating activities in 2020 totaled $49.7 million compared to $17.3 million in 2019. The increase in cash provided by operating activities in the current year was a result of an increase in current year net sales and the decrease in our net loss, but was also impacted by changes in current assets and liabilities which included increases in accounts receivable, inventory and accounts payable. A significant increase in net sales in the fourth quarter of 2020 and the timing of the resulting cash conversion cycle drove the $20.2 million increase in accounts receivable. The $15.0 million increase in inventory was driven by purchases from suppliers made to fulfill anticipated future shipments of products. Increased business activities in the fourth quarter and the timing of payments to our suppliers resulted in the $15.1 million increase in accounts payable. Cash provided by operating activities was also impacted by increases in accrued compensation, warranty and other liabilities which increased $4.7 million, driven primarily by increases in incentive compensation due to current year results. Advance payments from customers related to equipment orders expected to be fulfilled during 2021 has resulted in a $2.2 million increase in customer advances. Income taxes payable decreased $2.1 million a result of tax payments made in certain foreign jurisdictions.

Investing Activities: Investing cash flows consist primarily of cash used for capital expenditures in support of our business, purchases of investments, proceeds from investment maturities, business acquisitions, asset disposals and business divestitures. Our net cash used in investing activities in 2020 totaled $18.4 million. Additions to property, plant and equipment in 2020 were $18.7 million and were made to support the operating and development activities of our Semiconductor Test & Inspection segment. During 2020 we used $19.7 million in cash for purchases of short-term investments. We invest our excess cash, in an attempt to seek the highest available return while preserving capital, in short-term investments since excess cash may be required for a business-related purpose. During 2020 we generated cash totaling $17.0 million from the sale of land, buildings, and fixed assets as part of facility consolidation program and $3.0 million from the sale of our fixtures services business.

Financing Activities: In fiscal 2020, our cash used in financing activities totaled $38.1 million. During 2020, we paid dividends totaling $5.0 million, or $0.06 per common share. As a result of the COVID-19 pandemic, we are proactively managing cash flow and Cohu’s Board of Directors authorized suspending our quarterly cash dividend indefinitely, as of May 5, 2020. The dividend suspension will result in approximately $10 million of annualized cash savings, which we expect to utilize for deleveraging and strengthening our balance sheet. Repayments of short-term borrowings and long-term debt during fiscal 2020 totaled $41.1 million and included a $35.4 million repurchase and retirement of our Term Loan B debt during the third and fourth quarters of 2020 made to deleverage our balance sheet. We received proceeds under a revolving line of credit and construction loan totaling $5.9 million. Proceeds from the construction loan are being used to expand our facility in Kolbermoor, Germany, enabling us to consolidate the German operations of our Semiconductor Test & Inspection segment. Proceeds from the revolving line of credit are being used to increase the manufacturing capacity of our Semiconductor Test & Inspection segment facility located in Osaka, Japan. Net proceeds from the issuance of our common stock under our equity incentive and employee stock purchase plans, totaled $2.1 million during 2020. We issue share-based awards and maintain an employee stock purchase plan as components of our overall employee compensation.

Capital Resources

We have access to credit facilitates and other borrowings provided by financial institutions to finance acquisitions, capital expenditures and our operations if needed. A summary of our borrowings and available credit is as follows.

Credit Agreement

On October 1, 2018, we entered into a Credit Agreement providing for a $350.0 million Credit Facility and borrowed the full amount to finance a portion of the Xcerra acquisition. Loans under the Credit Facility amortize in equal quarterly installments of 0.25% of the original principal amount, with the balance payable at maturity. All outstanding principal and interest in respect of the Credit Facility must be repaid on or before October 1, 2025. The loans under the Term Loan Facility bear interest, at Cohu’s option, at a floating annual rate equal to LIBOR plus a margin of 3.00%. At December 26, 2020, the outstanding loan balance, net of discount and deferred financing costs, was $301.1 million and $2.4 million of the outstanding balance is presented as current installments of long-term debt in our consolidated balance sheets. At December 28, 2019, the outstanding loan balance, net of discount and deferred financing costs, was $339.1 million and $2.3 million of the outstanding balance is presented as current installments of long-term debt in our consolidated balance sheets.

Under the terms of the Credit Agreement, the lender may accelerate the payment terms upon the occurrence of certain events of default set forth therein, which include: the failure of Cohu to make timely payments of amounts due under the Credit Agreement, the failure of Cohu to adhere to the representations and covenants set forth in the Credit Agreement, the failure to provide notice of any event that causes a material adverse effect or to provide other required notices, upon the event that related collateral agreements become ineffective, upon the event that certain legal judgments are entered against Cohu, the insolvency of Cohu, or upon the change of control of Cohu. As of December 26, 2020, we believe no such events of default have occurred.

In the second half of 2020, we repurchased $36.4 million in principal of our Term Loan Facility for $35.4 million in cash. We accounted for the repurchase as a debt extinguishment, which resulted in a gain of $0.3 million reflected in other expense, net, in our consolidated statement of operations, as well as a $0.7 million reduction in debt discounts and deferred financing costs in our consolidated balance sheets. After the repurchase, approximately $306.6 million in principal of the Term Loan Facility remains outstanding as of December 26, 2020.

Kita Term Loans

As a result of our acquisition of Kita, we assumed term loans from a series of Japanese financial institutions primarily related to the expansion of Kita’s facility in Osaka, Japan. The loans are collateralized by the facility and land, carry interest rates ranging from 0.05% to 0.44%, and expire at various dates through 2034. At December 26, 2020, the outstanding loan balance was $3.6 million and $0.3 million of the outstanding balance is presented as current installments of long-term debt in our consolidated balance sheets. At December 28, 2019, the outstanding loan balance was $3.8 million and $0.4 million of the outstanding balance is presented as current installments of long-term debt in our consolidated balance sheets. The term loans are denominated in Japanese Yen and, as a result, amounts disclosed herein will fluctuate because of changes in currency exchange rates.

Xcerra Term Loan

As a result of our acquisition of Xcerra, we assumed a term loan related to the purchase of Xcerra’s facility in Rosenheim, Germany. The loan was payable over 10 years at an annual interest rate of 2.35%. Principal plus accrued interest was due quarterly over the duration of the term loan ending in March 2024. At December 28, 2019, the outstanding loan balance was $1.5 million and $0.3 million of the outstanding balance is presented as current installments of long-term debt in our consolidated balance sheets. During the third quarter of 2020 the term loan was fully repaid using proceeds received from the sale of our facility located in Rosenheim, Germany.

Construction Loans

On July 26, 2019, one of our wholly owned subsidiaries located in Germany entered into two construction loans (“Loan Facilities”) with a German financial institution providing total borrowing of €8.6 million. The Loan Facilities have 10-year and 15-year terms, which commenced on August 1, 2019, the initial draw-down date. Additionally, on June 16, 2020, a third construction loan with the same financial institution was entered into providing total borrowing of €1.5 million. This loan facility has a 10-year term, which has not commenced. The Loan Facilities are being utilized to finance the expansion of our facility in Kolbermoor, Germany, enabling us to combine the operations of multiple subsidiaries in one location as part of our previously announced strategic restructuring program. The Loan Facilities are secured by the land and the existing building on the site and bear interest at agreed upon rates based on separate €3.4 million, €5.2 million and €1.5 million facility amounts.

On August 1, 2019, the full €3.4 million was drawn under the first facility, which is payable over 10 years at an annual interest rate of 0.8%. Interest only payments are required to be made each quarter starting in September 2019 with principal and interest payments due each quarter starting in the month of December 2021. Principal repayments will be made over 8 years starting at the end of 2021.

Through December 26, 2020, we drew €4.9 million under the second facility, which is payable over 15 years at an annual interest rate of 1.05%. Interest only payments are required to be made each month starting in December 2019 with principal and interest payments due each month starting in the month of May 2020. Principal repayments will be made over 15 years starting at the end of May 2020. As of December 26, 2020, €0.3 million had not been drawn under the second facility.

Through December 26, 2020, no amounts have been drawn under the third facility. Future amounts, if drawn, will be payable over 10 years at an annual interest rate of 1.2%. Interest payments are required to be made each month starting in the month following the first draw-down date with principal and interest payments due each month starting in the month of May 2021. Principal repayments will be made over 10 years starting at the end of May 2021.

At December 26, 2020 and December 28, 2019, total outstanding borrowings under the Loan Facilities was $9.9 million and $5.5 million with $0.4 million and $0.3 million of the total outstanding balance being presented as current installments of long-term debt in our consolidated balance sheets based on contractual due dates, respectively. The loans are denominated in Euros and, as a result, amounts disclosed herein will fluctuate because of changes in currency exchange rates.

Lines of Credit

As a result of our acquisition of Kita, we assumed a series of revolving credit facilities with various financial institutions in Japan. The credit facilities renew monthly and provide Kita with access to working capital totaling up to $9.3 million. At December 26, 2020, total borrowings outstanding under the revolving lines of credit were $5.3 million. As these credit facility agreements renew monthly, they have been included in short-term borrowings in our consolidated balance sheets.

The revolving lines of credit are denominated in Japanese Yen and, as a result, amounts disclosed herein will fluctuate because of changes in currency exchange rates.

Our wholly owned Ismeca subsidiary has one available line of credit which provides it with borrowings of up to a total of 2.0 million Swiss Francs, a portion of which is reserved for tax guarantees. At December 26, 2020 and December 28, 2019, no amounts were outstanding under this line of credit.

We also have a letter of credit facility (“LC Facility”) under which Bank of America, N.A., has agreed to administer the issuance of letters of credit on our behalf. The LC Facility requires us to maintain deposits of cash or other approved investments in amounts that approximate our outstanding letters of credit and contains customary restrictive covenants. In addition, our wholly owned subsidiary, Xcerra, has arrangements with various financial institutions for the issuance of letters of credit and bank guarantees. As of December 26, 2020, $0.8 million was outstanding under standby letters of credit and bank guarantees.

We expect that we will continue to make capital expenditures to support our business and we anticipate that present working capital will be sufficient to meet our operating requirements for at least the next twelve months.

Contractual Obligations

The following table summarizes our significant contractual obligations at December 26, 2020, and the effect such obligations are expected to have on our liquidity and cash flows in future periods. Amounts excluded include our liability for unrecognized tax benefits that totaled approximately $33.7 million at December 26, 2020. We are currently unable to provide a reasonably reliable estimate of the amount or period(s) the cash settlement of this liability may occur.

The table above does not include pension, post-retirement benefit and warranty obligations because it is not certain when these liabilities will be funded. For additional information regarding our pension and post-retirement benefits obligations see Note 6, “Employee Benefit Plans” and for more information on our contractual obligations, see Note 13, “Guarantees” in Part IV, Item 15(a) of this Form 10-K.

Commitments to contract manufacturers and suppliers. From time-to-time, we enter into commitments with our vendors and outsourcing partners to purchase inventory at fixed prices or in guaranteed quantities. We are not able to determine the aggregate amount of such purchase orders that represent contractual obligations, as purchase orders may represent authorizations to purchase rather than binding agreements. Our purchase orders are based on our current manufacturing needs and are fulfilled by our vendors within relatively short time horizons. We typically do not have significant agreements for the purchase of raw materials or other goods specifying minimum quantities or set prices that exceed our expected requirements for the next three months.

Off-Balance Sheet Arrangements. During the ordinary course of business, we provide standby letters of credit instruments to certain parties as required. As of December 26, 2020, $0.8 million was outstanding under standby letters of credit.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Investment and Interest Rate Risk.

At December 26, 2020, our investment portfolio included short-term, fixed-income investment securities with a fair value of approximately $20.7 million, and we did not hold or issue financial instruments for trading purposes. These securities are subject to interest rate risk and will likely decline in value if interest rates increase. Our future investment income may fall short of expectations due to changes in interest rates or we may suffer losses in principal if we are forced to sell securities that decline in market value due to changes in interest rates. As we classify our short-term securities as available-for-sale, no gains or losses are recognized due to changes in interest rates unless such securities are sold prior to maturity or declines in fair value are determined to be other-than-temporary. Due to the relatively short duration of our investment portfolio, an immediate ten percent change in interest rates would have no material impact on our financial condition or results of operations.

We evaluate our investments periodically for possible other-than-temporary impairment by reviewing factors such as the length of time and extent to which fair value has been below cost basis, the financial condition of the issuer and our ability and intent to hold the investment for a period of time sufficient for anticipated recovery of market value. As of December 26, 2020, the cost and fair value of investments with loss positions were approximately $8.7 million. We evaluated the nature of these investments, credit worthiness of the issuer and the duration of these impairments and concluded that these losses were temporary and we have the ability and intent to hold these investments to maturity.

Our long-term debt is carried at amortized cost and fluctuations in interest rates do not impact our consolidated financial statements. However, the fair value of our debt will generally fluctuate with movements of interest rates, increasing in periods of declining rates of interest and declining in periods of increasing rates of interest. As of December 26, 2020, we have approximately $306.6 million of long-term debt due under a credit facility that is subject to quarterly interest payments that are based on either a base rate plus a margin of up to 2.0% per annum, or the London Interbank Offered Rate (LIBOR) plus a margin of up to 3.0% per annum. The selection of the interest rate formula is at our discretion. The interest rate otherwise payable under the credit facility will be subject to increase by 2.0% per annum during the continuance of a payment default and may be subject to increase by 2.0% per annum with respect to the overdue principal amount of any loans outstanding and overdue interest payments and other overdue fees and amounts. At December 26, 2020, the interest rate in effect on these borrowings was 3.15%.

In July 2017, the UK’s Financial Conduct Authority, which regulates the LIBOR, announced that it intends to phase out LIBOR by the end of 2021. After 2021, it is unclear whether banks will continue to provide LIBOR submissions to the administrator of LIBOR, and no consensus currently exists as to what benchmark rate or rates may become accepted alternatives to LIBOR. In the United States, efforts to identify a set of alternative U.S. dollar reference interest rates include proposals by the Alternative Reference Rates Committee that has been convened by the Federal Reserve Board and the Federal Reserve Bank of New York. We cannot currently predict the effect of the discontinuation of, or other changes to, LIBOR or any establishment of alternative reference rates in the United States, the European Union or elsewhere in the global capital markets. The uncertainty regarding the future of LIBOR, as well as the transition from LIBOR to any alternative reference rate or rates, could have adverse impacts on floating rate obligations, loans, deposits, derivatives and other financial instruments that currently use LIBOR as a benchmark rate. Our Term Loan B facility constitutes our most significant exposure to this transition and there is no guarantee that a shift from LIBOR to a new reference rate will not result in increases to our borrowing costs.

Foreign Currency Exchange Risk.

We have operations in several foreign countries and conduct business in the local currency in these countries. As a result, we have risk associated with currency fluctuations as the value of foreign currencies fluctuate against the U.S. dollar, in particular the Swiss Franc, Euro, Malaysian Ringgit, Chinese Yuan, Philippine Peso and Japanese Yen. These fluctuations can impact our reported earnings.

During the fourth quarter of 2020, we began entering into foreign currency forward contracts with a financial institution to hedge against future movements in foreign exchange rates that affect certain existing U.S. Dollar denominated assets and liabilities at our subsidiaries whose functional currency is the local currency. Under this program, our strategy is to have increases or decreases in our foreign currency exposures mitigated by gains or losses on the foreign currency forward contracts in order to mitigate the risks and volatility associated with foreign currency transaction gains or losses.

Fluctuations in currency exchange rates also impact the U.S. Dollar amount of our net investment in foreign operations. The assets and liabilities of our foreign subsidiaries are translated into U.S. Dollars at the exchange rates in effect at the fiscal year-end balance sheet date. Income and expense accounts are translated at an average exchange rate during the year which approximates the rates in effect at the transaction dates. The resulting translation adjustments are recorded in stockholders’ equity as a component of accumulated other comprehensive income. As a result of fluctuations in certain foreign currency exchange rates in relation to the U.S. Dollar as of December 26, 2020 compared to December 28, 2019, our stockholders’ equity increased by $27.3 million as a result of the foreign currency translation.

Based upon the current levels of net foreign assets, a hypothetical 10% devaluation of the U.S. dollar as compared to these currencies as of December 26, 2020 would result in an approximate $38.6 million positive translation adjustment recorded in other comprehensive income within stockholders’ equity. Conversely, a hypothetical 10% appreciation of the U.S. dollar as compared to these currencies as of December 26, 2020 would result in an approximate $38.6 million negative translation adjustment recorded in other comprehensive income within stockholders’ equity.

Item 9A. Controls and Procedures.

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures - Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Based on this evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures were effective as of December 26, 2020, the end of the period covered by this annual report.

Changes in Internal Control over Financial Reporting - During the three months ended December 26, 2020, certain of our wholly owned subsidiaries implemented an integrated finance/accounting and manufacturing software system. The implementations involved changes in systems that included internal controls, and accordingly, these changes have required changes to our system of internal controls.

We reviewed the systems as they were being implemented and the controls affected by the implementation of the new systems and made appropriate changes to affected internal controls during the implementation process. We believe that the controls as modified are appropriate and functioning effectively. This change was not in response to any identified deficiency or weakness in our internal control over financial reporting.

Other than those described above, there have been no changes in our internal control over financial reporting during the most recent fiscal quarter that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

Management’s Annual Report on Internal Control Over Financial Reporting - Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on our evaluation under the framework in Internal Control - Integrated Framework, our management concluded that our internal control over financial reporting was effective as of December 26, 2020.

Ernst & Young LLP, the independent registered public accounting firm that audited the Consolidated Financial Statements included in this Annual Report on Form 10-K, has also audited the effectiveness of our internal control over financial reporting as of December 26, 2020, as stated in their report which is included herein.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Cohu, Inc.

Opinion on Internal Control over Financial Reporting

We have audited Cohu, Inc.’s internal control over financial reporting as of December 26, 2020, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Cohu, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 26, 2020, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 26, 2020 and December 28, 2019, and the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity, and cash flows for each of the three years in the period ended December 26, 2020, and the related notes and the financial statement schedule listed in the Index at Item 15(a) and our report dated February 26, 2021, expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

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

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