          2019 Annual Report 

Dear Fellow Shareholders, 

Front and center for our company is the execution of our five-year growth strategy. The underlying secular 
themes of safety, resource efficiency and the ever-increasing connected world remain intact. These long-
term trends drive ever-greater sophistication in electrical architecture, increasing the content of our circuit 
protection,  power  control  and  sensing  products  in  applications  across  industrial,  transportation  and 
electronics end markets. We are committed to executing our growth strategy underpinned by these secular 
themes and our strong business fundamentals. 

When developing our strategy, we considered a period of soft demand, which we experienced in 2019 after 
several years of strong growth. During the year, our global teams remained focused on driving long-term 
growth, profitability, and cash generation, enabling us to successfully navigate a challenging end market 
environment. We balanced short-term cost containment, while continuing to make strategic investments to 
support our long-term growth objectives. For the full year, we achieved an adjusted operating margin of 14 
percent1,  adjusted  EBITDA  margin  of  20  percent2  and  generated  $183  million  in  free  cash  flow3  — 
representing a 132 percent conversion from net income of $139 million — exceeding our 100 percent target. 
We returned $140 million of our free cash flow to shareholders through dividends and share repurchases, 
reinforcing the strength of our balance sheet and reiterating our commitment to deliver ongoing value to our 
shareholders. 

Our  Industrial  product  segment  delivered  strong  performance  and  achieved  an  operating  margin  of 
approximately  20  percent.  Within  our  Automotive  product  segment,  we  drove  continued  profitability 
improvement and achieved double-digit operating margins. Through our close customer partnerships in our 
Electronics product segment, we managed a dynamic demand environment to deliver mid-teens operating 
margins. 

We advanced several strategic initiatives: 

•  Across our target end markets we secured key design wins for a wide range of applications in all 

regions. 

o  In industrial applications, we expanded our geographic presence with wins in power protection 
and  conversion  for  renewable  energy  projects  and  energy  storage,  temperature  sensors  for 
automated factories and HVAC systems, and power semiconductors for industrial motor drives. 
o  In  transportation  applications,  we  advanced  our  long-term  content  position  with  wins  in  the 
growing electric vehicle market for hybrid and electric vehicle battery systems and on-vehicle 
chargers,  power  control  and  distribution  systems 
for  commercial  vehicles,  power 
semiconductors for ignition systems, and solar, speed, position and fluid level sensors. 

o  In  electronics  applications,  we  leveraged  our  deep,  strategic  relationships  with  our  channel 
partners and end customers to capture wins in protection and power semiconductors for data 
centers and telecom infrastructure, consumer electronics, building and home automation, and 
sensors for home security systems and smart meters. 

As a trusted partner to our more than 100,000 end customers, we see the expanding need for our full 
range of protect, control and sensing technologies increasing across the end markets we serve. 

•  We took steps to optimize our global operations as we continued our integration of the IXYS business 
and also embarked on several infrastructure improvements to drive efficiency and increase capacity. 
We began construction of a new facility that will further expand our power semiconductor capabilities 
— a key driver of our growth strategy. Once completed, this strategic investment will build on the 
IXYS  acquisition  and  our  portfolio  of  high-performance  power  semiconductor  products.  We  are 
confident that these actions, as well as others planned, will continue to drive long-term growth and 
profitability. 

 
 
 
 
 
 
 
 
 
 
          2019 Annual Report 

•  As  a  testament  to  our  global  execution  oriented  culture,  we  again  earned  the  Association  for 
Manufacturing Excellence award — this time in Piedras Negras, Mexico. Notably, five of our facilities 
around the world have received this recognition over  the last four years. It is the innovation, hard 
work  and  dedication  of  our  11,000  worldwide  associates  that  affords  us  our  long-standing  global 
reputation  for  product  quality  and  reliability,  excellent  engineering  support  and  customer 
responsiveness. Operational excellence remains the foundation of our strong business fundamentals 
as evidenced by our repeated recognition. 

During  2019,  we  made  significant  progress  across  our  business  segments  and  end  markets  as  we 
continued  to  execute  our  growth  strategy  in  a  challenging  market.  We  are  confident  we  remain  well 
positioned  to  meet  the  changing  needs  of  our  customers,  pursue  continued  growth  and  maximize 
shareholder value. Looking ahead, our leading technologies, global footprint, close customer relationships 
and talented associates position us for continued long-term growth in excess of the markets we serve within 
the secular themes of safety, resource efficiency and the ever-increasing connected world.

NON-GAAP FINANCIAL MEASURES
The information included in the letter to shareholders includes the non-GAAP financial measures of adjusted operating margin, adjusted 
EBITDA margin and free cash flow. These non-GAAP financial measures exclude the effect of certain expenses and income not related 
directly to the underlying performance of our fundamental business operations. The company believes that adjusted operating margin and 
adjusted  EBITDA  margin  provide  useful information  to  investors  regarding  its  operational  performance  because  they  enhance  an  investor’s 
overall understanding of our core financial performance and facilitate comparisons  to  historical  results  of  operations,  by  excluding items that are 
not  related  directly  to  the  underlying  performance  of  our  fundamental  business  operations  or  historical  business  operations.  The  letter  to 
shareholders also includes the non-GAAP measure of free cash flow. The company believes free cash flow is a useful measure of its ability 
to  generate  cash.  A  reconciliation  of  these  non-GAAP  financial  measures  to  the  most  directly  comparable  GAAP  financial  measures  is 
included herein. The company believes that these non-GAAP financial measures are commonly used by financial analysts and others in 
the industries in which we operate, and thus further provide useful information to investors. Management additionally uses these measures 
when assessing the performance of the business and for business planning purposes. Note that our definitions of these non-GAAP financial 
measures may differ from those terms as  defined or used by other companies.

PRODUCT DESIGN AND DEVELOPMENT

The Company employs scientific, engineering, and other personnel to continually improve its existing product lines and to develop 
new products at its research, product design, and development (“R&D”) and engineering facilities with primary locations in  China, 
Germany, Italy, Japan, Lithuania, Mexico, Philippines, Taiwan(China), United Kingdom, and the U.S. The Company maintains a 
staff of engineers, chemists, material scientists and technicians whose primary responsibility is to design and develop new products.

Proposals for the development of new products are initiated primarily by sales, marketing, and product management personnel 
with input from customers. The entire product development process usually ranges from a few months to a few years based on 
the complexity of development, with continuous efforts to reduce the development cycle. During fiscal years 2019, 2018, and 
2017, the Company expended $80.5 million, $87.3 million, and $50.5 million, respectively, on R&D. 

PATENTS, TRADEMARKS, AND OTHER INTELLECTUAL PROPERTY

The Company generally relies on patents, trademarks, licenses, and nondisclosure agreements to protect its intellectual property 
and proprietary products. In cases where it is deemed necessary by management, key employees are required to sign an agreement 
that they will maintain the confidentiality of the Company’s proprietary information and trade secrets.

The Company owns a large portfolio of patents worldwide and new products are continually being developed to replace older 
products. The Company regularly applies for patent protection on such new products. While, in the aggregate, the Company’s 
patents are important in the operation of its businesses, the Company believes that the loss by expiration or otherwise of any one 
patent or group of patents would not materially affect its business.

MANUFACTURING

The Company’s manufacturing facilities are in China, Germany, Italy, Japan, Lithuania, Mexico, Philippines, Portugal, the United 
Kingdom, and the United States. The Company performs the majority of its own fabrication and maintains in-house capabilities 
for metal stamping, surface mount assembly, plating (silver, nickel, zinc, and oxides) and thermoplastic molding. In addition, the 
Company fabricates semiconductor wafers for certain applications and maintains in-house capability for epitaxy fabrication, die 
attach, and wafer probe testing. After sub-components are readied for assembly, final assembly is accomplished on fully automatic 
and semi-automatic assembly machines. Quality assurance and operations personnel, using techniques such as statistical process 
control, perform tests, checks and measurements during the production process to maintain the highest levels of product quality, 
including  safety  and  reliability,  and  customer  satisfaction. Additionally,  the  Company  utilizes  external  wafer  foundries  and 
subcontracted test and assembly facilities for a portion of its semiconductor business.

The principal raw materials for the Company’s products include copper and copper alloys, heat-resistant plastics, zinc, melamine, 
glass, silver, gold, raw silicon, solder, and various gases. The Company uses a single source for several heat-resistant plastics and 
for zinc but has specifically identified capable alternative heat-resistant plastics and zinc sources. All other raw materials are 
purchased from a number of readily available outside sources.

MARKETING

The Company goes to market through a worldwide selling organization consisting of direct sales personnel, distribution partners 
and  manufacturers’  representatives. The  direct  sales  force  closely  works  with  global  OEM, Tier  One  automotive,  consulting 
engineers, and major end customers to design-in and sell the Company’s circuit protection, power control and sensing products. 
The distributors provide fulfillment for a majority of customers including those partnered with electronic manufacturing services 
("EMS"). The direct sales force is supplemented with manufacturers’ representatives. The Company has sales offices and direct 
sales channels in all major regions of the world.

Electronics Segment

Most Electronics segment products are sold through broad line distribution partners, including global distributors such as Arrow 
Electronics, Inc., Future Electronics and TTI, Inc, and regional and high service distributors, including Digi-Key and Mouser, as 
well  as  directly  to  OEM's.  Many  of  our  products  are  incorporated  into  applications  with  complex  design  technical  support 
requirements.  These may be sold through our direct salesforce and fulfilled through our distribution partners. 

7

Automotive Segment

The Company primarily uses a direct sales force to service all of the major automotive and commercial vehicle OEMs, system 
suppliers, and Tier One automotive and aftermarket customers globally.

The Company also leverages its automotive customer relationships to sell products from the Electronics segment into automotive 
end markets, primarily to Tier One automotive customers. These revenues are reported in the Electronics segment.

Industrial Segment

The Company markets and sells its power fuses and protection relays through manufacturers’ representatives, and industrial and 
electrical distributors, primarily across North America and through a worldwide direct sales force & electronics channels. The 
electrical and industrial distribution network includes electrical contractors, municipalities, utilities and factories.  

CUSTOMERS

The Company directly sells to nearly 6,400 customers and distributors worldwide. Sales to Arrow Electronics, Inc., which were 
reported in our Electronics, Automotive and Industrial segments, were 10.7%, 10.7% and 10.6% of consolidated net sales in 2019, 
2018, and 2017, respectively. No other single customer accounted for more than 10% of net sales during any of the last three years.
During fiscal 2019, 2018, and 2017, net sales to customers outside the U.S. accounted for approximately 71%, 70%, and 69%, 
respectively, of the Company’s total net sales.

COMPETITION

The Company’s products compete with similar products of other manufacturers, some of which may have substantially greater 
financial resources than the Company. In the Electronics segment, the Company’s competitors include Eaton Corporation, Bel 
Fuse  Inc.,  Bourns  Inc.,  EPCOS,  ON  Semiconductor  Corporation,  Infineon  Technologies,  STMicroelectronics  NV,  Semtech 
Corporation, and Vishay Intertechnology Inc. In the Automotive segment, the Company’s competitors include Eaton Corporation,

and performance of its products based on their reliability, consistency and safety, its technical capabilities and application expertise, 
and the responsiveness of its customer service.

BACKLOG

The  backlog  of  unfilled  orders  at  December 28,  2019  was  approximately  $477.6  million,  compared  to  $405.7  million  at 
December 29, 2018 with the increase primarily driven by the Electronics segment, partially offset by a decrease from the Automotive 
segment. Substantially all the orders currently in backlog are scheduled for delivery in 2020.

EMPLOYEES

As  of  December 28,  2019,  the  Company  employed  approximately  11,300  employees  worldwide. Approximately  20%  of  the 
Company's total workforce was employed under collective bargaining agreements at December 28, 2019. In Mexico, the Company 
has two separate collective bargaining agreements, one for 1,758 employees in Piedras Negras, expiring January 31, 2022 and the 
second for 600 employees in Matamoros, expiring January 1, 2022. In Germany, the Company has collective bargaining agreements 
with approximately 375 employees in Lampertheim and Essen, expiring March 31, 2020. In the United Kingdom, the Company 
has  a  collective  bargaining  agreement  with  some  of  the  employees  in  Chippenham.  Overall,  the  Company  has  historically 
maintained satisfactory employee relations and considers employee relations to be good.

ENVIRONMENTAL REGULATION

The Company is subject to numerous foreign, federal, state, and local regulations relating to air and water quality, the disposal of 
hazardous waste materials, safety and health. Compliance with applicable environmental regulations has not significantly changed 
the Company’s competitive position, capital spending or earnings in the past and the Company does not presently anticipate that 
compliance with such regulations will change its competitive position, capital spending or earnings for the foreseeable future.

The Company believes that it is currently in compliance in all material respects with applicable environmental laws and regulations.

8

Littelfuse GmbH, which was acquired by the Company in May 2004, is responsible for maintaining closed coal mines in Germany 
from legacy operations. The Company is compliant with German regulations pertaining to the maintenance of the mines and has 
an accrual related to certain of these coal mine shafts based on an engineering study estimating the cost of remediating the dangers 
(such as a shaft collapse) of certain of these closed coal mine shafts in Germany. The accrual is reviewed annually and calculated 
based upon the estimated costs of remediating the shafts. Further information regarding the coal mine liability accrual is provided 
in Note 1, Summary of Significant Accounting Policies and Other Information, of the Notes to Consolidated Financial Statements 
included in this Annual Report.

ITEM 1A. RISK FACTORS.

The Company’s business, financial condition, and results of operations are subject to various risks and uncertainties, including 
the risk factors it has identified below. Any of the following risk factors could materially and adversely affect the Company’s 
business, financial condition, or results of operations. These factors are not necessarily listed in order of importance.

1) Operational Risks:

The Company’s industry is subject to intense competitive pressures.

The Company operates in markets that are highly competitive. The Company competes on the basis of price, product performance 
and quality, service, and / or brand name across the industries and markets it serves. Competitive pressures could affect the prices 
the Company is able to charge its customers or demand for its products.

The Company may not always be able to compete on price, particularly when compared to manufacturers with lower cost structures. 
Some of the Company’s competitors have substantially greater sales, financial and manufacturing resources and may have greater 
access to capital than the Company. As other companies enter its markets or develop new products, competition may further 
intensify. The Company’s failure to compete effectively could materially adversely affect its business, financial condition, and 
results of operations.

The Company engages in strategic acquisitions and may not realize the anticipated benefits of the acquisitions and / or may 
encounter difficulties in integrating these businesses.

The Company seeks to grow through strategic acquisitions. In the past, the Company has acquired a number of businesses or 
companies and additional product lines and assets. The Company intends to continue to expand and diversify its operations with 
additional future acquisitions.

An acquired business, technology, service or product could under-perform relative to the Company’s expectations and the price 
paid for it, or not perform in accordance with the Company’s anticipated timetable. This could cause the Company’s financial 
results to differ from expectations in any given fiscal period, or over the long term. The success of these transactions also depends 
on the Company’s ability to integrate the assets, operations, and personnel associated with these acquisitions. The Company may 
encounter difficulties in integrating acquisitions with the Company’s operations and may not realize the degree or timing of the 
benefits that are anticipated from an acquisition.

The Company may also discover liabilities or deficiencies associated with the companies or assets it acquires that were not identified 
in advance, which may result in significant unanticipated costs. The effectiveness of the Company’s due diligence review and its 
ability to evaluate the results of such due diligence are dependent upon the accuracy and completeness of statements and disclosures 
made or actions taken by the companies acquired or their representatives, as well as the limited amount of time in which acquisitions 
are executed. In addition, the Company may fail to accurately forecast the financial impact of an acquisition transaction, including 
tax and accounting charges. Acquisitions may also result in recording of significant additional expenses to the results of operations 
and recording of substantial intangible assets on the balance sheet upon closing. Any of these factors may adversely affect the 
Company’s financial condition and results of operations.

Disruptions in the Company’s manufacturing, supply or distribution chain could result in an adverse impact on results of 
operations.

The Company sources materials and sells product through various international network channels. A disruption could occur within 
the Company’s manufacturing, distribution or supply chain network. This could include damage or destruction due to various 
causes including natural disasters or political instability which would cause one or more of these network channels to become 
non-operational. This could adversely affect the Company’s ability to manufacture or deliver its products in a timely manner, 

9

impair its ability to meet customer demand for products and result in lost sales or damage to its reputation. Such a disruption could 
have a material adverse effect on the Company’s business, financial condition and results of operations.

The Company may be unable to manufacture and deliver products in a manner that is responsive to its customers’ needs.

The end markets for the Company’s products are characterized by technological change, frequent new product introductions and 
enhancements, changes in customer requirements and emerging industry standards. The introduction of products embodying new 
technologies and the emergence of new industry standards could render its existing products obsolete and unmarketable before it 
can recover any or all of its research, development, and commercialization expenses on capital investments. Furthermore, the life 
cycles of its products may change and are difficult to estimate.

The Company’s future success will depend upon its ability to manufacture and deliver products in a manner that is responsive to 
its customers’ needs. The Company will need to develop and introduce new products and product enhancements on a timely basis 
that  keep  pace  with  technological  developments  and  emerging  industry  standards  and  address  increasingly  sophisticated 
requirements of its customers. The Company invests heavily in research and development without knowing that it will recover 
these costs. The Company’s competitors may develop products or technologies that will render its products non-competitive or 
obsolete. If it cannot develop and market new products or product enhancements in a timely and cost-effective manner, its business, 
financial condition and results of operations could be materially adversely affected.

The Company’s business may be interrupted by labor disputes or other interruptions of supplies.

A work stoppage could occur at certain Company facilities, most likely as a result of disputes under collective bargaining agreements 
or in connection with negotiations of new collective bargaining agreements. In addition, the Company may experience a shortage 
of supplies for various reasons, such as financial distress, work stoppages, natural disasters, or production difficulties that may 
affect one of its suppliers. A significant work stoppage, or an interruption or shortage of supplies for any reason, if protracted, 
could substantially adversely affect the Company’s business, financial condition and results of operations. The transfer of the 
Company’s manufacturing operations and changes in its distribution model could disrupt operations for a limited time.

Failure to attract and retain qualified personnel could affect the Company’s business results.

The Company’s success, both generally and in connection with mergers and acquisitions, depends on the Company’s ability to 
attract, retain, and motivate a highly-skilled and diverse management team and workforce. Failure to ensure that the Company 
has the depth and breadth of personnel with the necessary skill set and experience could impede its ability to deliver growth 
objectives and execute the Company’s strategy. Competition for qualified employees among companies that rely heavily upon 
engineering and technology is at times intense, and the loss of qualified employees could hinder the Company’s ability to conduct 
research activities successfully and develop marketable products.

The Company may not be successful protecting its intellectual property.

The Company considers its intellectual property, including patents, trade names, and trademarks, to be of significant value to its 
business as a whole. The Company’s products are manufactured, marketed, and sold under a portfolio of patents, trademarks, 
licenses, and other forms of intellectual property, some of which expire or are allowed to lapse at various dates in the future. The 
Company develops and acquires new intellectual property on an ongoing basis and considers all of its intellectual property to be 
valuable. The Company's policy is to file applications and obtain patents for the great majority of its novel and innovative new 
products including product modifications and improvements. Based on the broad scope of its product lines, the Company believes 
that the loss or expiration of any single intellectual property right would not have a material adverse effect upon its consolidated 
results of operations, financial position  and cash flows; however, multiple losses or expirations could have a material adverse 
effect upon the Company’s consolidated results of operations, financial position  and cash flows.

2) Regulatory Risks:

Changes in U.S. and other countries trade policy, including the imposition of tariffs and the resulting consequences, may have 
a material adverse impact on our business and results of operations.

The U.S. government has adopted a new approach to trade policy and in some cases to renegotiate, or potentially terminate, certain 
existing bilateral or multi-lateral trade agreements. It has also imposed tariffs on certain foreign goods and products. These measures 
may materially increase costs for goods imported into the United States. This in turn could require us to materially increase prices 
to our customers which may reduce demand, or, if we do not or are unable to increase prices, could result in lower margins on 
products sold. Changes in U.S. trade policy have resulted in, and could result in more, U.S. trading partners adopting responsive 
10

trade policies making it more difficult or costly for us to export our products to those countries. Additionally, continued geo-
political issues may result in customers in China seeking to source products from local suppliers, which could result in lower sales 
or lost customers.

The Company is exposed to political, economic, and other risks that arise from operating a multinational business.

The Company's customers, suppliers, employees and operations are located in numerous countries around the world, and contribute 
significantly to its revenues and earnings. Sales to customers outside the U.S. constituted approximately 71% of the Company's 
net sales in fiscal 2019. Many of the Company's key customers are located outside of U.S. and maintain global operations. Serving 
a global customer base and remaining competitive in the global marketplace requires the Company to diversify its operations 
outside the U.S. to capitalize on customer and market opportunities, build a global workforce and maintain a cost efficient structure. 
In addition, the Company sources a significant amount of raw materials, components and finished goods from third-party suppliers 
and contract manufacturers.  The Company’s operating activities are subject to a number of risks generally associated with multi-
national operations, including risks relating to the following:

•
•
•
•
•
•
•
•
•
•
•
•
•
•
•

general economic conditions;
currency fluctuations and exchange restrictions;
import and export duties and restrictions;
the imposition of tariffs and other import or export barriers;
compliance with regulations governing import and export activities;
current and changing regulatory requirements;
political and economic instability;
potentially adverse income tax consequences;
transportation delays and interruptions;
labor unrest;
natural disasters;
terrorist activities;
public health concerns, including the recent outbreak of the coronavirus impacting China and elsewhere;
difficulties in staffing and managing multi-national operations; and
limitations on the Company’s ability to enforce legal rights and remedies.

More recently, the coronavirus outbreak originating from China at the beginning of 2020 has resulted in extended shutdowns of 
numerous business activities in the region and supply chain disruptions, which has impacted the sales, production and shipment 
of products in and out of its borders. These shutdowns and disruptions have impacted the Company’s manufacturing and supply 
chain operations, as well as those of its suppliers, contract manufacturers and customers. As new developments continue to arise, 
the Company is not yet able to fully ascertain the impact on its sales, manufacturing, supply chain and operations to its business 
and financial results, both inside and outside of China. Health concerns in China or other countries in which the Company or the 
Company’s suppliers, contract manufacturers and customers operate could result in social, economic, and labor instability. 

Any of these factors could have a material adverse effect on the Company’s consolidated results of operations, financial position 
and cash flows.

Environmental liabilities could adversely impact the Company’s financial position.

Foreign,  federal,  state  and  local  laws  and  regulations  impose  various  restrictions  and  controls  on  the  discharge  of  materials, 
chemicals and gases used in the Company’s manufacturing processes or in its finished goods. These environmental regulations 
have required the Company to expend a portion of its resources and capital on relevant compliance programs. Under these laws 
and regulations, the Company could be held financially responsible for remedial measures if its current or former properties are 
contaminated or if it sends waste to a landfill or recycling facility that becomes contaminated, even if the Company did not cause 
the contamination. The Company may be subject to additional common law claims if it releases substances that damage or harm 
third  parties.  In  addition,  future  changes  in  environmental  laws  or  regulations  may  require  additional  investments  in  capital 
equipment or the implementation of additional compliance programs. Any failure to comply with new or existing environmental 
laws or regulations could subject the Company to significant liabilities and could have a material adverse effect on its consolidated 
results of operations, financial position and cash flows.

In the conduct of manufacturing operations, the Company has handled and does handle materials that are considered hazardous, 
toxic or volatile under federal, state, and local laws. The risk of accidental release of such materials cannot be completely eliminated. 
In addition, the Company operates or owns facilities located on or near real property that was formerly owned and operated by 
others. Certain of these properties were used in ways that involved hazardous materials. Contaminants may migrate from, within 
11

or  through  these  properties.  These  releases  or  migrations  may  give  rise  to  claims.  Where  third  parties  are  responsible  for 
contamination, the third parties may not have funds, or not make funds available when needed, to pay remediation costs imposed 
upon the Company under environmental laws and regulations.

The Company is responsible for the maintenance of discontinued coal mining operations in Germany. The risk of environmental 
remediation exists, and the Company is in the process of remediating the mines considered to be the most at risk.

3) Financial Risks:

Reorganization activities may lead to additional costs and material adverse effects.

In the past, the Company has taken actions to restructure and optimize its production and manufacturing capabilities and efficiencies 
through relocations, consolidations, plant closings or asset sales. In the future, the Company may take additional restructuring 
actions including the consolidating, closing or selling of additional facilities. These actions could result in impairment charges 
and various charges for such items as idle capacity, disposition costs and severance costs, in addition to normal or attendant risks 
and uncertainties. The Company may be unsuccessful in any of its current or future efforts to restructure or consolidate its business. 
Plans to minimize or eliminate any loss of revenues during restructuring or consolidation may not be achieved. These activities 
may have a material adverse effect upon the Company’s business, financial condition and results of operations.

The Company’s ability to manage currency or commodity price fluctuations or supply shortages is limited.

As a resource-intensive manufacturing operation, the Company is exposed to a variety of market and asset risks, including the 
effects of changes in commodity prices, foreign currency exchange rates, and interest rates. The Company has multiple sources 
of supply for the majority of its commodity requirements. However, significant shortages that disrupt the supply of raw materials 
or result in price increases could affect prices the Company charges its customers, its product costs, and the competitive position 
of its products and services. The Company monitors and manages these exposures as an integral part of its overall risk management 
program,  which  recognizes  the  unpredictability  of  markets  and  seeks  to  reduce  the  potentially  adverse  effects  on  its  results. 
Nevertheless, changes in currency exchange rates, commodity prices and interest rates cannot always be predicted. In addition, 
because of intense price competition and the Company’s high level of fixed costs, it may not be able to address such changes even 
if they are foreseeable. Substantial changes in these rates and prices could have a material adverse effect on the Company’s results 
of operations and financial condition. In addition, significant portions of its revenues and earnings are exposed to changes in 
foreign currency rates. As it operates in multiple foreign currencies, changes in those currencies relative to the U.S. dollar will 
impact its revenues and expenses. The impact of possible currency devaluation in countries experiencing high inflation rates or 
significant exchange fluctuations can impact the Company’s results and financial guidance. For additional discussion of interest 
rate, currency or commodity price risk, see Item 7A, Quantitative and Qualitative Disclosures about Market Risk.

The Company’s effective tax rate could materially increase as a consequence of various factors, including interpretations 
and administrative guidance in regard to the Tax Act (defined below), U.S. and/or international tax legislation, mix of the 
Company’s earnings by jurisdiction, and U.S. and non-U.S. jurisdictional tax audits.

On December 22, 2017, the U.S. enacted legislation commonly referred to as the Tax Cuts and Jobs Act (the "Tax Act"). Although 
certain administrative guidance has been issued, the appropriate application of many provisions of the Tax Act remain uncertain. 
As discussed more fully in Note 14, Income Taxes, of the Notes to Consolidated Financial Statements included in this Annual 
Report, adjustments to income tax expense may be necessary in future periods if provisions of the Tax Act, and their interaction 
with other provisions of the U.S. Internal Revenue Code, are interpreted differently than interpretations made by the Company, 
whether through issuance of additional administrative guidance, or through further review of the Tax Act by the Company and its 
advisors. Such adjustments could have a material adverse effect on the Company’s future effective tax rate and cash flows.

The Company is subject to taxes in the U.S. and numerous non-U.S. jurisdictions. Therefore, it is subject to changes in tax laws 
in each of these jurisdictions. Certain European jurisdictions, including Germany and the Netherlands, have enacted or will enact 
tax legislation based upon directives from the European Union. Such legislation could potentially deny tax deductions for certain 
expenses and/or subject to tax the income earned in certain low tax jurisdictions. Although the Company believes such legislation 
will not adversely impact its future effective tax rate, there can be no assurance that its analysis, based upon the currently available 
information, is correct. The Company’s income tax rate in certain non-U.S. jurisdictions, including the Philippines, is substantially 
lower than the U.S. statutory tax rate. Legislative proposals have been made from time to time to reduce these tax benefits, in 
some cases with the tax increase phased in over a multi-year transition period. The Philippines is currently contemplating such 

12

legislation which could adversely impact the Company's future effective tax rate. The outcome of these and other legislative 
developments, including changes to interpretations of recently enacted legislation, could have a material adverse effect on the 
Company’s future effective tax rate and cash flows.

The Organization for Economic Co-operation and Development is working with a group of more than 100 countries to seek 
agreement to modify the international tax system before the end of 2020 to address the influence of the digital economy. This 
effort could result in a significant change to the tax treatment of multinationals, subjecting them to tax in additional jurisdictions, 
modifying the methods by which they allocate profits among jurisdictions, and subjecting them to a global or country by country 
minimum level of tax. The outcome of this effort could have a material adverse effect on the Company’s effective tax rate and 
cash flows.    

The Company has three subsidiaries in China which benefit from lower tax rates due to “tax holidays” which apply for three-year 
periods, subject to extension. The tax holiday for two of these subsidiaries expired at the end of 2019 (one will seek an extension 
and the tax holiday benefits for the other is not material). The tax holiday for the third subsidiary will expire the end of 2020 and 
it will seek an extension. There can be no assurance that such extensions will be granted.

The tax rates applicable in the jurisdictions within which the Company operates vary widely. Therefore, the Company’s effective 
tax rate may be adversely affected by changes in the mix of its earnings by jurisdiction.

The Company’s tax returns are subject to examination by various U.S. and non-U.S. tax authorities, including the U.S. Internal 
Revenue Service. The Company regularly assesses the likelihood of an adverse outcome resulting from these examinations to 
determine  the  adequacy  of  its  provision  for  income  taxes.  However,  there  can  be  no  assurance  as  to  the  outcome  of  these 
examinations.

A decline in expected profitability of the Company or individual reporting units of the Company could result in the impairment 
of assets, including goodwill and other long-lived assets.

The Company holds material amounts of goodwill and other long-lived assets on its balance sheet. A decline in expected profitability, 
particularly if there is a decline in the global economy, could call into question the recoverability of the Company’s related goodwill 
and other long-lived tangible and intangible assets and require the write-down or write-off of these assets. Such an occurrence 
could have a material adverse effect on the Company’s consolidated results of operations, financial position and cash flows.

A significant fluctuation between the U.S. dollar and other currencies could adversely impact the Company's revenue and 
earnings.

Although  the  Company's  financial  results  are  reported  in  U.S.  dollars,  the  majority  of  the  Company’s  operations  consist  of 
manufacturing and sales activities in foreign countries. The Company’s most significant net long exposure is to the euro. The 
Company’s most significant net short exposures are to the Chinese renminbi, Mexican peso, and Philippine peso. Changes in 
foreign exchange rates could have an adverse effect on the Company's results of operations, financial position and cash flows.

The Company’s revenues may vary significantly from period to period.

The Company’s revenues may vary significantly from one period to another due to a variety of factors including:

•
•
•
•
•
•
•
•
•
•
•
•

changes in customers’ buying decisions;
changes in demand for its products;
changes in its distributor inventory stocking;
the Company’s product mix;
the Company’s effectiveness in managing manufacturing processes;
costs and timing of its component purchases;
the effectiveness of its inventory control;
the degree to which it is able to utilize its available manufacturing capacity;
the Company’s ability to meet delivery schedules;
general economic and industry conditions;
local conditions and events that may affect its production volumes, such as labor conditions and political instability; and
seasonality of certain product lines.

13

The bankruptcy or insolvency of a major customer could adversely affect the Company.

The bankruptcy or insolvency of a major customer could result in lower sales revenue and cause a material adverse effect on the 
Company’s consolidated results of operations, financial position and cash flows. In addition, the bankruptcy or insolvency of a 
major auto manufacturer or significant supplier likely could lead to substantial disruptions in the automotive supply base, resulting 
in lower demand for the Company’s products, which would likely cause a decrease in sales revenue and have a substantial adverse 
impact on the Company’s consolidated results of operations, financial position and cash flows.

The inability to maintain access to capital markets may adversely affect the Company’s business and financial results.

The Company’s ability to invest in its businesses, make strategic acquisitions, and refinance maturing debt obligations may require 
access to the capital markets and sufficient bank credit lines to support short-term borrowings. If the Company is unable to access 
the capital markets or bank credit facilities, it could experience a material adverse effect on its consolidated results of operations, 
financial position and cash flows.

Fixed costs may reduce operating results if sales fall below expectations.

The Company’s expense levels are based, in part, on its expectations for future sales. Many of the Company’s expenses, particularly 
those relating to capital equipment and manufacturing overhead, are relatively fixed. The Company might not be able to reduce 
spending quickly enough to compensate for reductions in sales. Accordingly, shortfalls in sales could materially and adversely 
affect the Company’s consolidated results of operations, financial position and cash flows.

The volatility of the Company’s stock price could affect the value of an investment in the Company’s stock and future 
financial position.

The market price of the Company’s stock can fluctuate widely. Between December 29, 2018 and December 28, 2019, the closing 
sale price of the Company’s common stock ranged between a low of $149.80 and a high of $206.00. The volatility of the stock 
price may be related to any number of factors, such as volatility in the financial markets, general macroeconomic conditions, 
industry  conditions,  market  expectations  concerning  the  Company’s  results  of  operations,  or  the  volatility  of  its  revenues  as 
discussed above under “The Company’s Revenues May Vary Significantly from Period to Period.” The historic market price of 
the Company’s common stock may not be indicative of future market prices. The Company may not be able to sustain or increase 
the value of its common stock. Declines in the market price of the Company’s stock could adversely affect the Company’s ability 
to retain personnel with stock incentives, to acquire businesses or assets in exchange for stock and/or to conduct future financing 
activities with or involving the Company’s common stock.

The Company is exposed to, and may be adversely affected by, potential security breaches or other disruptions to its 
information technology systems and data security.

The Company relies on its information technology systems and networks in connection with many of its business activities. Some 
of these networks and systems are managed directly by the Company, while others are managed by third-party service providers 
and are not under the Company’s direct control. The Company’s operations routinely involve receiving, storing, processing and 
transmitting sensitive information pertaining to its business, customers, dealers, suppliers, employees, and other sensitive matters. 
As with most companies, the Company has experienced cyber-attacks, attempts to breach its systems, and other similar incidents, 
none of which have been material. Any future cyber incidents could, however, materially disrupt operational systems; result in 
loss of trade secrets or other proprietary or competitively sensitive information; compromise personally identifiable information 
regarding employees or customers or other third parties; and jeopardize the security of the Company’s facilities. A cyber incident 
could be caused by malicious outsiders using sophisticated methods to circumvent firewalls, encryption, and other security defenses. 
Because techniques used to obtain unauthorized access or to sabotage systems change frequently and generally are not recognized 
until they are launched against a target, the Company may be unable to anticipate these techniques or to implement adequate 
preventative measures. Information technology security threats, including security breaches, computer malware, and other cyber-
attacks are increasing in both frequency and sophistication and could create financial liability, subject the Company to legal or 
regulatory sanctions or damage the Company’s reputation with customers, dealers, suppliers, and other stakeholders. The Company 
continuously seeks to maintain a robust program of information security and controls, but the impact of a material information 
technology event could have a material adverse effect on the Company’s competitive position, reputation, results of operations, 
financial position and cash flows.

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

The Dodd-Frank Wall Street Reform and Consumer Protection Act requires disclosure of use of “conflict” minerals mined from 
the Democratic Republic of Congo and adjoining countries and efforts to prevent the use of such minerals. In the semiconductor 
industry, these minerals are most commonly found in metals. As there may be only a limited number of suppliers offering “conflict 
free” metals, the Company cannot be certain that it will be able to obtain necessary metals in sufficient quantities or at competitive 
prices. Also, the Company may face challenges with its customers and suppliers if it is unable to sufficiently verify that the metals 
used in its products are “conflict free.”

BUSINESS

For a description of the Company’s business, segments and product offerings, see Item 1, Business.

2019 EXECUTIVE OVERVIEW

Net sales decreased by $214.6 million, or 12.5%, in 2019 compared to 2018. The decrease was primarily driven by lower volume 
across the Electronics and Automotive segments and $25.0 million or 1.5% of unfavorable changes in foreign exchange rates, 
partially offset by higher volume in the Industrial segment. The Company recognized net income of $139.1 million, or $5.60 per 
diluted share, in 2019 compared to net income of $164.6 million, or $6.52 per diluted share in 2018. The decrease in net income 
reflects  lower  operating  income  in  the  Electronics  and Automotive  segments,  partially  offset  by  lower  non-segment  charges 
compared to prior year primarily due to the IXYS acquisition.

The Company continues to take actions to improve its cost structure and drive the synergies from the integration of IXYS. The 
Company expects to realize cost savings from the restructuring activities taken during 2019 including the reorganization of certain 
19

manufacturing, selling and administrative functions across all segments and the closure of a European manufacturing facility in 
the automotive sensors business within the Automotive segment. 

Net cash provided by operating activities was $245.3 million for the year ended December 28, 2019 as compared to $331.8 million
for the year ended December 29, 2018. The decrease in net cash provided by operating activities was primarily driven by lower 
earnings and higher working capital levels primarily due to the timing of supplier payments, payroll year-end cut off and higher 
annual incentive compensation payments in 2019.

During the fiscal year 2019, the Company repurchased 579,916 shares of its common stock totaling $95.0 million. During the 
fiscal year 2018, the Company repurchased 391,972 shares of its common stock totaling $67.9 million.  From September 30, 2018 
until December 28, 2019, the Company repurchased 971,888 shares of its common stock at an average price of $167.65 totaling 
$162.9 million.

OUTLOOK

Vision and Strategy

The Company works with its customers to design and develop technologies that help them build safer, more reliable and more 
efficient products for a safer, greener and increasingly connected world in virtually every market that uses electrical energy; for 
example, automotive and commercial vehicles, industrial applications like renewable energy and storage, motor drives and power 
conversion, data and telecommunications, medical devices, consumer electronics and appliances. Built upon that framework, the 
Company’s strategy is centered on growing its circuit protection, power control and sensor platforms.

The Company’s strategic plan is focused on increasing shareholder value by driving profitable sales growth, earnings per share 
growth, strong cash flow generation, and deploying capital consistent with its long-term capital allocation priorities. The Company 
pursues the following major strategic initiatives, which are summarized below, along with more specific areas of focus.

Strategic Objective

2020 and Future Priorities

Double digit sales growth

EPS growth

Cash flow and liquidity

Grow through increased product content with existing customers and
increased market share
Expand portfolio into new and underpenetrated geographies and end markets
Increase innovation capabilities and investments
Expand presence in products and applications that are converging across
business segments
Targeted mergers and acquisitions

Focus on higher profitability growth opportunities
Improve operating margins through operational excellence
Disciplined approach to balancing costs with long-term strategic investments

Disciplined management of working capital
Deployment of capital consistent with capital allocation priorities
Mergers and acquisitions that align with strategy and financial metrics
Grow dividend in line with earnings
Opportunistic share repurchases

The Company’s strategy is to generate profitable sales growth. In order to accomplish this, the Company is focusing on accelerating 
organic growth by increasing its content and share gains, enhancing technology efforts to drive innovation, capitalizing on cross 
segment opportunities, and gaining traction in underpenetrated geographies and markets. The Company will continue to make 
targeted strategic acquisitions that align to its strategy and financial metrics to support new business, products, markets, and 
technologies while leveraging existing customers and targeting new customers.

Management believes that profitable growth through a combination of organic growth and strategic acquisitions is critical to the 
Company’s competitiveness, while enhancing value the Company delivers to its customers and other stakeholders. In addition, 

20

the Company continues to implement initiatives across all platforms to enhance productivity while managing its cost structure to 
align with business conditions, including integration of operations and streamlining administrative and support activities to drive 
improved operating margins.

The Company seeks to deploy its capital consistent with capital allocation priorities. Priorities for capital deployment, over time, 
include investments to drive increased organic growth, targeted acquisitions that align to the Company’s strategic and financial 
metrics and returning capital to shareholders through dividends and opportunistic share repurchases.

The Company uses several key indicators to gauge progress toward achieving these objectives. These indicators include organic 
sales growth, operating margins, cash flow from operations and capital expenditures. Through cycles, the Company targets double-
digit long-term (2017-2021) sales growth, split between 5-7% average annual accelerated organic sales growth and 5-7% average 
annual accelerated growth from strategic acquisitions, while targeting operating margins between 17% and 19% and double-digit 
earnings per share growth. Cash flow from operations less capital expenditures is targeted to approximate or exceed net income 
but in any given year can be significantly impacted by the timing of non-recurring or infrequent expenditures.

Significant Accounting Policies and Critical Estimates

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that 
affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial 
statements and the reported amounts of revenues and expenses during the reporting period. The Company’s most critical accounting 
policies are those that are most important to the portrayal of its financial condition and results of operations, and which require 
the Company to make its most difficult and subjective judgments, often as a result of the need to make estimates of matters that 
are inherently uncertain. The Company has identified the following as its most critical accounting policies and judgments. Although 
management believes that its estimates and assumptions are reasonable, they are based upon information available when they are 
made, and therefore, actual results may differ from these estimates under different assumptions or conditions. The Company has 
reviewed these critical accounting policies and related disclosures with the Audit Committee of its Board of Directors. Significant 
accounting policies are more fully described in the Notes to Consolidated Financial Statements included elsewhere in this Annual 
Report.

Revenue Recognition

 On  December  31,  2017,  the  Company  adopted  new  guidance  on  revenue  from  contracts  with  customers  using  the  modified 
retrospective method. The adoption did not have a significant impact on the Company’s consolidated financial statements.

Revenue Recognition

The Company recognizes revenue on product sales in the period in which the Company satisfies its performance obligation and 
control of the product is transferred to the customer. The Company’s sales arrangements with customers are predominately short 
term in nature and generally provide for transfer of control at the time of shipment as this is the point at which title and risk of 
loss of the product transfers to the customer. At the end of each period, for those shipments where title to the products and the risk 
of loss and rewards of ownership do not transfer until the product has been received by the customer, the Company adjusts revenues 
and cost of sales for the delay between the time that the products are shipped and when they are received by the customer. The 
amount of revenue recorded reflects the consideration to which the Company expects to be entitled in exchange for goods and 
may include adjustments for customer allowance, rebates and price adjustments. The Company’s distribution channels are primarily 
through direct sales and independent third-party distributors.

The Company has elected the practical expedient under Accounting Standards Codification ("ASC") 340-40-25-4 to expense 
commissions when incurred as the amortization period of the commission asset the Company would have otherwise recognized 
is less than one year.

Revenue and Billing

The Company generally accepts orders from customers through receipt of purchase orders or electronic data interchange based 
on written sales agreements and purchasing contracts. Contract pricing and selling agreement terms are based on market factors, 
costs, and competition. Pricing is often negotiated as an adjustment (premium or discount) from the Company’s published price 
lists. The  customer  is  invoiced  when  the  Company’s  products  are  shipped  to  them  in  accordance  with  the  terms  of  the  sales 
agreement. As the Company’s standard payment terms are less than one year, the Company has elected the practical expedient 
under ASC 606-10-32-18 to not assess whether a contract has a significant financing component. The Company also elected the 
practical expedient provided in ASC 606-10-25-18B to treat all product shipping and handling activities as fulfillment activities, 
and therefore recognize the gross revenue associated with the contract, inclusive of any shipping and handling revenue. This is 
similar to the Company’s prior practice and therefore the effect of the new guidance is immaterial.

Ship and Debit Program

Some of the terms of the Company’s sales agreements and normal business conditions provide customers (distributors) the ability 
to receive price adjustments on products previously shipped and invoiced. This practice is common in the industry and is referred 
to as a “ship and debit” program. This program allows the distributor to debit the Company for the difference between the distributors’ 
contracted price and a lower price for specific transactions. Under certain circumstances (usually in a competitive situation or 
large volume opportunity), a distributor will request authorization for pricing allowances to reduce its price. When the Company 
approves such a reduction, the distributor is authorized to “debit” its account for the difference between the contracted price and 
the lower approved price. The Company establishes reserves for this program based on historic activity, electronic distributor 
inventory levels and actual authorizations for the debit and recognizes these debits as a reduction of revenue.

22

Return to Stock 

The Company has a return to stock policy whereby certain customers, with prior authorization from the Company's management, 
can return previously purchased goods for full or partial credit. The Company establishes an estimated allowance for these returns 
based on historic activity. Sales revenue and cost of sales are reduced to anticipate estimated returns.

Volume Rebates

The Company offers volume-based sales incentives to certain customers to encourage greater product sales. If customers achieve 
their specific quarterly or annual sales targets, they are entitled to rebates. The Company estimates the projected amount of rebates 
that will be achieved by the customer and recognizes this estimated cost as a reduction to revenue as products are sold.

Allowance for Doubtful Accounts: 

The Company evaluates the collectability of its trade receivables based on a combination of factors. The Company regularly 
analyzes its significant customer accounts and, when the Company becomes aware of a specific customer’s inability to meet its 
financial obligations, the Company records a specific reserve for bad debt to reduce the related receivable to the amount the 
Company reasonably believes is collectible. The Company also records allowances for all other customers based on a variety of 
factors including the length of time the receivables are past due, the financial health of the customer, macroeconomic considerations 
and past experience. Historically, the allowance for doubtful accounts has been adequate to cover bad debts. If circumstances 
related to specific customers change, the estimates of the recoverability of receivables could be further adjusted.

Inventory

The  Company  performs  regular  detailed  assessments  of  inventory,  which  include  a  review  of,  among  other  factors,  demand 
requirements, product life cycle and development plans, component cost trends, product pricing, shelf life, and quality issues. 
Based on the analysis, the Company records adjustments to inventory for excess quantities, obsolescence or impairment when 
appropriate to reflect inventory at net realizable value. Historically, inventory reserves have been adequate to reflect inventory at 
net realizable values.

Goodwill

The Company’s methodology for allocating the purchase price of acquisitions is based on established valuation techniques that 
reflect  the  consideration  of  a  number  of  factors,  including  valuations  performed  by  third-party  appraisers  when  appropriate. 
Goodwill is measured as the excess of the cost of an acquired entity over the fair value assigned to identifiable assets acquired 
and liabilities assumed. Based on its current organization structure, the Company has seven reporting units for which cash flows 
are determinable and to which goodwill has been allocated. 

The Company annually tests goodwill for impairment on the first day of its fiscal fourth quarter, or more frequently if an event 
occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. 
The Company also performs an interim review for indicators of impairment each quarter to assess whether an interim impairment 
review is required for any reporting unit. As part of its interim reviews, management analyzes potential changes in the value of 
individual reporting units based on each reporting unit’s operating results for the period compared to expected results as of the 
prior year’s annual impairment test. In addition, management considers how other key assumptions, including discount rates and 
expected long-term growth rates, used in the last annual impairment test, could be impacted by changes in market conditions and 
economic events. Based on the interim assessments, management concluded that no events or changes in circumstances indicated 
that it was more likely than not that the fair value for any reporting unit had declined below its carrying value.

Quantitative Assessment for Impairment

For the seven reporting units with goodwill, the Company compares the estimated fair value of each reporting unit to its carrying 
value. If the carrying value of a reporting unit exceeded the estimated fair value, the difference between the estimated fair value 
and carrying value is recorded as the amount of the goodwill impairment charge. The results of the goodwill impairment test as 
of September 30, 2019 indicated that the estimated fair values for each of the seven reporting units exceeded their respective 
carrying values. Accordingly, there were no goodwill impairment charges recorded as part of the Company’s 2019 annual goodwill 
impairment test.

As part of its impairment test for these reporting units, the Company engaged a third-party appraisal firm to assist in the Company’s 
determination of the estimated fair values. This determination included estimating the fair value of each reporting unit using both 
23

the income and market approaches. The income approach requires management to estimate a number of factors for each reporting 
unit, including projected operating results, economic projections, anticipated future cash flows, discount rates and the allocation 
of shared or corporate items. The market approach estimates fair values using comparable marketplace fair value data from within 
a comparable industry grouping. The Company weighted both the income and market approach equally to estimate the concluded 
fair  value  of  each  reporting  unit.  The  determination  of  fair  value  requires  the  Company  to  make  significant  estimates  and 
assumptions, which primarily include, but are not limited to: the selection of appropriate peer group companies; control premiums 
appropriate for acquisitions in which the Company competes; the discount rate; terminal growth rates; and forecasts of revenue, 
operating income, depreciation and amortization and capital expenditures.

Goodwill Impairment Assumptions

Although the Company believes its estimates of fair value are reasonable, actual financial results could differ from those estimates 
due to the inherent uncertainty involved in making such estimates. Changes in assumptions concerning future financial results or 
other underlying assumptions could have a significant impact on the fair value of the reporting units. Future declines in the overall 
market value of the Company’s equity may also result in a conclusion that the fair value of one or more reporting units has declined 
below its carrying value.

One measure of the sensitivity of the amount of goodwill impairment charges to key assumptions is the amount by which each 
reporting unit “passed” (fair value exceeds the carrying value) the goodwill impairment test. All seven of the reporting units passed 
the goodwill impairment test, with fair values that exceeded the carrying values by between 40% and 268% of their respective 
estimated fair values. As of the most recent annual test conducted on September 30, 2019, the Company noted that the excess of 
fair value over the carrying value, was 217%, 42%, 137%, 213%, 40%, 89%, and 268% for its reporting units: Electronics-Passive 
Products and Sensors, Electronics-Semiconductor, Passenger Car Products, Commercial Vehicle Products, Automotive Sensors, 
Relays, and Power Fuse, respectively. Relatively small changes in the Company’s key assumptions would not have resulted in 
any reporting units failing the goodwill impairment test.

Generally, changes in estimates of expected future cash flows would have a similar effect on the estimated fair value of the reporting 
unit. That is, a 1.0% decrease in estimated annual future cash flows would decrease the estimated fair value of the reporting unit 
by approximately 1.0%. The estimated long-term net sales growth rate can have a significant impact on the estimated future cash 
flows, and therefore, the fair value of each reporting unit. A 1.0% decrease in the long-term net sales growth rate would have 
resulted in no reporting units failing the goodwill impairment test. Of the other key assumptions that impact the estimated fair 
values, most reporting units have the greatest sensitivity to changes in the estimated discount rate. The estimated discount rate 
was 9.7% for the Electronics-Semiconductor, Passenger Car Products and Commercial Vehicle Products reporting units, and 10.7% 
for the Electronics-Passive Products and Sensor reporting unit and 11.7% for the Automotive Sensors, Power Fuse and Relays 
reporting units. A 1.0% increase in the estimated discount rates would have resulted in no reporting units failing the annual goodwill 
impairment test. The Company believes that its estimates of future cash flows and discount rates are reasonable, but future changes 
in the underlying assumptions could differ due to the inherent uncertainty in making such estimates. Additionally, price deterioration 
or lower volume could have a significant impact on the fair values of the reporting units.

Long-Lived Assets

The  Company  evaluates  the  recoverability  of  other  long-lived  assets,  including  property,  plant  and  equipment  and  certain 
identifiable intangible assets, whenever events or changes in circumstances indicate that the carrying value of an asset or asset 
group may not be recoverable. Factors which could trigger an impairment review include significant underperformance relative 
to historical or projected operating results, significant changes in the manner of use of the assets or the strategy for the overall 
business, a significant decrease in the market value of the assets or significant negative industry or economic trends. When the 
Company determines that the carrying value of long-lived assets may not be recoverable based upon the existence of one or more 
of the indicators, the assets are assessed for impairment based on the estimated future undiscounted cash flows expected to result 
from the use of the asset and its eventual disposition. If the carrying value of an asset exceeds its estimated future undiscounted 
cash flows, an impairment loss is recorded for the excess of the asset’s carrying value over its fair value. During the year-ended 
December 28, 2019, the Company recognized non-cash impairment charges of $0.3 million for certain machinery and equipment 
related to the closure of a European manufacturing facility in the automotive sensors business within the Automotive segment. 
During the year ended December 29, 2018, the Company recognized non-cash impairment charges of $1.6 million and $0.5 million 
related to a building for sale and the Custom Products reporting unit trade name, respectively, associated with the exit of the 
Custom business within the Industrial Segment. During the year ended December 30, 2017, the Company recognized a loss of 
$2.9 million related to certain machinery and equipment in the Electronics and Automotive segments due to changes in the expected 
use of these certain assets.

24

Environmental Liabilities

Environmental liabilities are accrued based on estimates of the probability of potential future environmental exposure. Costs 
related to on-going maintenance of environmental sites are expensed as incurred. If actual or estimated probable future losses 
exceed the Company’s recorded liability for such claims, it would record additional charges as other expense during the period in 
which the actual loss or change in estimate occurred. The Company evaluates its reserve for coal mine remediation annually 
utilizing a third-party expert.

Pension and Supplemental Executive Retirement Plan

The Company records annual income and expense amounts relating to its pension and postretirement benefits plans based on 
calculations  which  include  various  actuarial  assumptions  including  discount  rates,  expected  long-term  rates  of  return  and 
compensation increases. The Company reviews its actuarial assumptions on an annual basis as of the fiscal year-end balance sheet 
date (or more frequently if a significant event requiring remeasurement occurs) and modifies the assumption based on current 
rates and trends when it is appropriate to do so. The effects of modifications are recognized immediately on the Consolidated 
Balance Sheets but are generally amortized into operating earnings over future periods, with the deferred amount recorded in 
accumulated other comprehensive income (loss). The Company believes that the assumptions utilized in recording its obligations 
under its plans are reasonable based on its experience, market conditions and input from its actuaries and investment advisors. 
The Company maintains several pension plans in international locations. The expected returns on plan assets and discount rates 
are determined based on each plan’s investment approach, local interest rates and plan participant profiles. The weighted-average
discount rates for the Company’s defined benefit plans primarily in Europe and the Asia-Pacific regions at December 28, 2019 
and December 29, 2018 were 2.3% and 3.1%, respectively.

A 50 basis point change in the discount rates at December 28, 2019 would have the following effect on the projected benefit

Equity-based compensation expense is recorded for stock-option awards and restricted share units based upon the fair values of 
the awards. The fair value of stock-option awards is estimated at the grant date using the Black-Scholes option pricing model, 
which includes assumptions for volatility, expected term, risk-free interest rate and dividend yield. Expected volatility is based 
on implied volatilities from traded options on Littelfuse stock, historical volatility of Littelfuse stock and other factors. Historical 
data is used to estimate employee termination experience and the expected term of the options. The risk-free interest rate is based 
on the U.S. Treasury yield curve in effect at the time of grant. The Company initiated a quarterly cash dividend in 2010 and expects 
to continue making cash dividend payments in the foreseeable future. The fair value of restricted share units is determined based 
on the Company's stock price on the grant date reduced by the present value of expected dividends through the vesting period.

Total equity-based compensation expense for all equity compensation plans was $19.9 million, $28.2 million, and $17.3 million 
in  2019,  2018,  and  2017,  respectively.  Further  information  regarding  this  expense  is  provided  in  Note  12,  Stock-Based 
Compensation, of the Notes to Consolidated Financial Statements included in this Annual Report.

Income Taxes

The Company accounts for income taxes using the liability method. Deferred taxes are recognized for the future effects of temporary 
differences between financial and income tax reporting using tax rates in effect for the years in which the differences are expected 
to reverse. The Company recognizes deferred taxes for temporary differences, operating loss carryforwards and tax credit and 
other tax attribute carryforwards (excluding carryforwards where usage has been determined to be remote). Deferred tax assets 
are reduced by a valuation allowance if it is more likely than not that some portion, or all, of the deferred tax assets will not be 
realized. U.S. state and non-U.S. income taxes are provided on the portion of non-U.S. income that is expected to be remitted to 
the U.S. and be taxable (and non-U.S. income taxes are provided on the portion of non-U.S. income that is expected to be remitted 
to an upper-tier non-U.S. entity). Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on 
the date of enactment.

25

Deferred income taxes are not provided on the excess of the investment value for financial reporting over the tax basis of investments 
in those non-U.S. subsidiaries for which such excess is considered to be permanently reinvested in those operations. Management 
regularly evaluates whether non-U.S. earnings are expected to be permanently reinvested. This evaluation requires judgment about 
the future operating and liquidity needs of the Company and its non-U.S. subsidiaries. Changes in economic and business conditions, 
non-U.S. or U.S. tax laws (such as the Tax Act), or the Company’s financial situation could result in changes to these judgments 
and the need to record additional tax liabilities.

The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will 
be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized 
in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood 
of being realized upon ultimate settlement.

On December 22, 2017, the U.S. enacted legislation commonly referred to as the Tax Cuts and Jobs Act (the "Tax Act"). Among 
other things, the Tax Act reduces the U.S. corporate federal income tax rate from 35% to 21%, adds base broadening provisions 
which limit deductions and address excessive international tax planning, imposes a one-time tax (the “Toll Charge”) on accumulated 
earnings of certain non-U.S. subsidiaries and enables repatriation of earnings of non-U.S. subsidiaries free of U.S. federal income 
tax. Other than the Toll Charge (which, except for the IXYS impact, was applicable to the Company for 2017), the provisions are 
generally applicable to the Company in 2018 and beyond.

In accordance with the guidance provided in SEC Staff Accounting Bulletin (“SAB”) No. 118, in the fourth quarter of 2017 the 
Company recorded a charge of $47.0 million as a provisional reasonable estimate of the impact of the Tax Act, including $49.0 
million for the Toll Charge net of $2.0 million for other net tax benefits. In the fourth quarter of 2018, within the measurement 
period outlined in SAB No. 118, the Company finalized its estimates of the impact of the Tax Act as of December 29, 2018 and 
recorded a charge of $3.2 million, including $2.3 million for the Toll Charge and $0.9 million for the net impact of other items. 
In addition, the Company recorded $7.0 million for the Toll Charge associated with IXYS as part of the IXYS acquisition purchase 
price allocation. This was reflected in the opening balance sheet as an increase to goodwill and other long-term liabilities.

One of the base broadening provisions of the Tax Act is the global intangible low-taxed income provisions ("GILTI"). In accordance 
with guidance issued by the FASB staff, the Company has adopted an accounting policy to treat any GILTI inclusions as a period 
cost if and when incurred. Thus, for the fiscal years ended December 28, 2019 and December 29, 2018, deferred taxes were 
computed without consideration of the possible future impact of the GILTI provisions, and any current year impact was recorded 
as a part of the current portion of income tax expense.

Further information regarding income taxes, including a detailed reconciliation of current year activity, is provided in Note 14, 
Income Taxes, of the Notes to Consolidated Financial Statements included in this Annual Report.

Off-Balance Sheet Arrangements

The Company does not have off-balance sheet arrangements as defined under SEC rules. The Company does not participate in 
transactions that generate relationships with unconsolidated entities or financial partnerships, such as entities often referred to as 
structured finance or special purpose entities.

26

In the financial review that follows, the Company discusses its consolidated results of operations, financial position, cash flows 
and certain other information. This discussion should be read in conjunction with the Company’s Consolidated Financial Statements 
and related notes.

RESULTS OF OPERATIONS FOR THE YEAR ENDED DECEMBER 28, 2019 AS COMPARED TO THE YEAR 
ENDED DECEMBER 29, 2018

The fiscal year 2019 included approximately $21.9 million of non-segment charges, of which $8.9 million of charges are acquisition- 
related and integration charges primarily related to the IXYS acquisition and other contemplated acquisitions, and $13.0 million
of restructuring charges primarily related to employee termination costs. See Note 8, Restructuring, Impairment and Other Charges, 
for further discussion.

The fiscal year 2018 included approximately $88.7 million of non-segment charges, of which $82.9 million of charges are primarily 
related to the IXYS acquisition as described in Note 2, Acquisitions and Dispositions, of the Notes to Consolidated Financial 
Statements included in this Annual Report. These charges include $36.9 million of purchase accounting inventory step-up charges, 
$18.7 million in acquisition-related and integration costs primarily related to legal, accounting and other expenses, $12.4 million 
in backlog amortization costs, $8.3 million of employee termination costs and other restructuring charges, $4.5 million of stock 
compensation expense recognized immediately upon close for converted IXYS options related to prior service periods, and $2.1 
million change in control expense related to IXYS. In addition, there were $5.8 million of employee termination costs, impairment 
and other restructuring charges and acquisition-related expenses for other contemplated acquisitions, which included charges 
associated with the exit of the Custom business in the second quarter within the Industrial segment.

Fiscal year 2019 also included approximately $5.2 million in foreign currency exchange losses primarily attributable to changes
in  the  value  of  the  euro,  Chinese  renminbi,  and  Japanese Yen  against  the  U.S.  dollar,  while  fiscal  year  2018  also  included 
approximately $0.9 million in foreign currency exchange gains primarily attributable to changes in the value of the euro, Mexico 
peso, Philippine peso and Chinese renminbi against the U.S. dollar.

Net sales for 2019 of $1,503.9 million decreased $214.6 million, or 12.5%, compared to the prior year primarily due to lower 
volume across the Electronics and Automotive segments driven by electronics distribution partners and end customers reducing 
excess inventories, a decline in global auto production and a decline in global end market demand, and $25.0 million or 1.5% of 
unfavorable changes in foreign exchange rates. 

Gross Profit

Gross profit was $541.4 million, or 36.0% of net sales, in 2019, compared to $652.5 million, or 38.0% of net sales, in 2018. The 
decrease in gross profit is primarily due to lower volumes across the Electronics and Automotive segments driven by electronics 
distribution partners and end customers reducing excess inventories, a decline in global auto production and a decline in global 

27

end market demand, unfavorable price and product mix, and costs related to restructuring activities taken during 2019. In 2018 
the IXYS purchase accounting inventory step-up charge of $36.9 million negatively impacted the 2018 gross margin by 2.1%.

Operating Expenses

Total operating expenses were $348.7 million, or 23.2% of net sales, for 2019 compared to $427.5 million, or 24.9% of net sales, 
for 2018. The decrease in operating expenses of $78.8 million was primarily due to lower annual incentive compensation expenses, 
reduced backlog amortization expense of $12.4 million, lower acquisition-related and integration costs of $11.3 million, global 
cost saving initiatives, and $4.5 million stock compensation expense and $2.1 million of change in control expense related to the 
2018 IXYS acquisition.

Operating Income

Operating income for 2019 was $192.8 million, a decrease of $32.3 million or 14.3% compared to $225.0 million for 2018. The 
decrease in operating income is primarily due to lower gross profit across the Electronics and Automotive segments, partially 
offset by lower operating expenses noted above and the $36.9 million purchase accounting inventory step-up charges in 2018. 
Operating margins decreased from 13.1% in 2018 to 12.8% in 2019 primarily driven by lower gross profit margin discussed above.

Income Before Income Taxes

Income before income taxes for 2019 was $165.9 million, or 11.0% of net sales compared to $204.9 million, or 11.9% of net 
sales, for 2018. In addition to the factors impacting comparative results for operating income discussed above, income before 
income taxes was unfavorably impacted by foreign exchange losses of $5.2 million during the fiscal year ended December 28, 
2019 compared to foreign exchange gains of $0.9 million during the fiscal year ended December 29, 2018, and decreases of 
$1.0 million in other income primarily due to the impairment charges of $7.3 million for certain other investments and a $2.6 
million loss on the disposal of a business within the Electronics segment during the fiscal year 2019,  partially offset by 
unrealized investment gains associated with our equity investments and higher interest income.

Income Taxes

Income tax expense for 2019 was $26.8 million, or an effective tax rate of 16.2% compared to income tax expense of $40.4 million, 
or an effective tax rate of 19.7%, for 2018. The 2019 income tax expense includes a benefit of $3.3 million from the recognition 
of previously unrecognized tax benefits (and the reversal of the related accrued interest) due to a lapse in the statute of limitations.
The 2018 income tax expense includes a charge of $3.2 million associated with finalizing the 2017 provisional reasonable 
estimate, including $2.3 million for the Toll Charge and $0.9 million for the net impact of other items. Additionally, our tax 
rates are lower than the applicable U.S. statutory tax rate primarily due to income earned in lower tax jurisdictions, partially 
offset by the impact of taxes on unremitted earnings, the GILTI tax provisions and non-U.S. losses and expenses with no tax 
benefit.

Segment Information

The Company reports its operations by the following segments: Electronics, Automotive and Industrial. Segment information is 
described more fully in Note 16, Segment Information, of the Notes to Consolidated Financial Statements included in this Annual

Electronics Segment

The Electronics segment net sales decreased $163.2 million, or 14.5%, in 2019 compared to 2018 primarily due to lower volume 
across all businesses due to electronics distribution partners and end customer reducing excess  inventories, a decline in global 
end market demand, and unfavorable changes in foreign exchange rates of $13.5 million.

Automotive Segment

Net sales in the Automotive segment decreased $51.3 million, or 10.7%, in 2019 compared to 2018 due to lower volume across 
all  businesses  primarily  from  a  decline  in  global  auto  production,  declines  in  commercial  vehicle  end  market  demand,  and 
unfavorable changes in foreign exchange rates of $10.9 million.

Industrial Segment

The Industrial segment net sales decreased slightly by $0.1 million, or 0.1%, in 2019 compared to 2018 primarily due to the exit 
of the Custom business during the second quarter of 2018 and unfavorable changes in foreign exchange rates of $0.6 million, 
partially offset by higher volume across all businesses.

foreign exchange rates of $6.8 million.

Americas

Net sales in the Americas decreased $70.2 million, or 12.1%, in 2019 compared to 2018 primarily due to lower volume  across 
all businesses within the Electronics segment and the Automotive segment, the exit of the Custom business within Industrial 
segment during the second quarter of 2018 and unfavorable changes in foreign exchange rates of $0.8 million, partially offset by 
higher volume in the power fuse and relay business within Industrial segments.

Europe

European net sales decreased $47.8 million, or 12.4%, in 2019 compared to 2018. The decrease in net sales was primarily due to 
lower volume across all businesses within the Electronics segment and the Automotive segment, and unfavorable changes in 
foreign exchange rates of $17.4 million, partially offset by higher volume in the power fuse business within the Industrial segment.

RESULTS OF OPERATIONS FOR THE YEAR ENDED DECEMBER 29, 2018 AS COMPARED TO THE YEAR 
ENDED DECEMBER 30, 2017

The following table summarizes the Company’s consolidated results of operations for periods presented. The fiscal year 2018 
includes approximately $88.7 million of non-segment charges, of which $82.9 million of charges are primarily related to the IXYS 
acquisition as described in Note 2, Acquisitions and Dispositions, of the Notes to Consolidated Financial Statements included in 
this Annual  Report. These  charges  include  $36.9  million  of  purchase  accounting  inventory  step-up  charges,  $18.7  million  in 
acquisition-related  and  integration  costs  primarily  related  to  legal,  accounting  and  other  expenses,  $12.4  million  in  backlog 
amortization costs, $8.3 million of employee termination costs and other restructuring charges, $4.5 million of stock compensation 
expense recognized immediately upon close for converted IXYS options related to prior service periods, and $2.1 million change 
in control expense related to IXYS. In addition, there were $5.8 million of employee termination costs, impairment and other 
restructuring charges and acquisition-related expenses for other contemplated acquisitions and included charges associated with 
the exit of the Custom business in the second quarter within the Industrial segment.

The  fiscal  year  2017  includes  approximately  $10.3  million  of  non-segment  charges.  These  included  acquisition-related  and 
integration costs related to legal, accounting and other expenses associated with completed or pending acquisitions of approximately 
$8.0 million, including $1.6 million of purchase accounting inventory charges related to the Company’s 2017 acquisition of U.S. 
Sensor as described in Note 2, Acquisitions and Dispositions, of the Notes to Consolidated Financial Statements included in this 
Annual Report, and $2.2 million of charges related to restructuring and production transfers in the Company’s Asia operations.

Fiscal year 2018 also included approximately $0.9 million in foreign currency exchange gains primarily attributable to changes 
in the value of the euro, Mexico peso, Philippine peso and Chinese renminbi against the U.S. dollar, while fiscal year 2017 also 
included approximately $2.4 million in foreign currency exchange losses primarily attributable to changes in the value of the euro, 
Philippine peso and Chinese renminbi against the U.S. dollar.

Net sales for 2018 of $1,718.5 million increased $496.9 million, or 40.7%, compared to the prior year with increases of $378.2 
million and $6.5 million resulting from incremental net sales related to the IXYS and U.S. Sensor acquisitions, respectively, $16.7 
million of favorable changes in foreign exchange rates, and volume growth across all three segments.

Gross Profit

Gross profit was $652.5 million, or 38% of net sales, in 2018, compared to $506.5 million, or 41.5% of net sales, in 2017. The 
increase in gross profit reflects the IXYS acquisition and volume growth and expense leverage across all segments. The decrease 
in gross margin is primarily due to the purchase accounting inventory charges of $36.9 million, which negatively impacted gross 
margin by 2.1 percentage points, and an unfavorable mix of products from the IXYS acquisition, which historically had lower 
gross margins.

 Operating Expenses

Total operating expenses were $427.5 million, or 24.9% of net sales, for 2018 compared to $288.0 million, or 23.6% of net sales, 
for 2017. The increase in operating expenses of $139.5 million was primarily due to the incremental operating expenses related 

30

to the IXYS and U.S. Sensor acquisitions, an increase in amortization expense of $27.5 million resulting from the acquisition of 
IXYS as well as higher acquisition-related and integration costs of $12.1 million. Total operating expenses as a percent of net 
sales increased from 23.6% in 2017 to 24.9% in 2018 primarily due to the higher amortization expense and acquisition-related 
and integration charges noted above.

Operating Income

Operating income for 2018 was $225.0 million, an increase of $6.5 million or 3.0% compared to $218.5 million for 2017. The 
increase in operating income is primarily due to the acquisition of IXYS and volume growth in the Electronics and Industrial 
segments, partially offset by $36.9 million of purchase accounting inventory charges, higher acquisition-related and integration 
charges and amortization expense. Operating margins decreased from 17.9% in 2017 to 13.1% in 2018 driven by the purchase 
accounting inventory charges, higher amortization expense and acquisition-related and integration charges that negatively impacted 
margins by 2.1%, 1.6% and 0.7%, respectively.

Income Before Income Taxes

Income before income taxes for 2018 was $204.9 million, or 11.9% of net sales compared to $204.0 million, or 16.7% of net 
sales, for 2017. In addition to the factors impacting comparative results for operating income discussed above, income before 
income taxes was unfavorably impacted by higher interest expense of $9.2 million mainly resulting from increased borrowings, 
partially offset by  increases in foreign exchange gains of $3.2 million.

Income Taxes

Income tax expense for 2018 was $40.4 million, or an effective tax rate of 19.7% compared to income tax expense of $84.5 million, 
or an effective tax rate of 41.4%, for 2017. The 2018 income tax expense includes a charge of $3.2 million associated with finalizing 
the 2017 provisional reasonable estimate, including $2.3 million for the Toll Charge and $0.9 million for the net impact of other 
items. The 2017 income tax expense includes a charge of $47 million as a provisional reasonable estimate of the impact of the 
Tax Act, including $49 million for the Toll Charge net of $2 million for other net tax benefits. Additionally, our tax rates are lower 
than the applicable U.S. statutory tax rate primarily due to income earned in lower tax jurisdictions, partially offset by the impact 
of taxes on unremitted earnings, and, with respect to 2018, the impact of the GILTI provisions of the Tax Act and non-U.S. losses 
and expenses with no tax benefit.

The Electronics segment net sales increased $462.4 million, or 69.9%, in 2018 compared to 2017 due to incremental net sales 
related to the IXYS and U.S. Sensor acquisitions of $378.2 million and $6.5 million, respectively, volume growth driven by the 
continued strong demand across various end markets and geographies, and favorable foreign exchange impacts of $6.5 million.

Automotive Segment

Net sales in the Automotive segment increased $26.6 million, or 5.9%, in 2018 compared to 2017 due to volume growth across 
all businesses primarily led by the commercial vehicle and sensor businesses, and favorable foreign exchange impacts of $9.8 
million.

Industrial Segment

The Industrial segment net sales increased $8.0 million, or 7.5%, in 2018 compared to 2017 primarily due to volume growth in 
the power fuse and relay businesses and favorable foreign exchange impacts of $0.4 million, partially offset by a decline in sales 
from the exit of the Custom business during 2018.

Asia-Pacific net sales increased $212.2 million, or 39.2%, in 2018 compared to 2017. The increase in net sales was primarily due 
to incremental net sales related to the IXYS acquisition of $173.9 million and volume growth across all segments as well as 
favorable foreign exchange impacts of $3.7 million.

Americas

Net sales in the Americas increased $142.1 million, or 32.6%, in 2018 compared to 2017 driven by incremental net sales related 
to the IXYS and U.S. Sensor acquisitions of $90.7 million and $5.5 million, respectively, volume growth across all segments and 
favorable foreign exchange impacts of $0.4 million.

Europe

European net sales increased $142.7 million, or 58.5%, in 2018 compared to 2017. The increase in net sales was primarily due to 
incremental net sales related to the IXYS acquisition of $113.6 million with volume growth across the Electronics and Automotive 
segments as well as favorable foreign exchange impacts of $12.6 million. 

Liquidity and Capital Resources

Cash and cash equivalents were $531.1 million as of December 28, 2019, an increase of $41.4 million as compared to December 29, 
2018.

As of December 28, 2019, $333.2 million of the Company's $531.1 million cash and cash equivalents was held by non-U.S. 
subsidiaries. Of the $333.2 million, at least $165 million can be repatriated with minimal tax consequences, although in certain 
cases a non-U.S. withholding tax would be payable but subsequently refunded. With respect to the remaining $168.2 million, the 
Company has recognized deferred tax liabilities on approximately $78.5 million as of December 28, 2019 because the amounts 
are not considered to be permanently reinvested, and the Company may access additional amounts through loans and other means. 
Repatriation of some non-U.S. cash balances is restricted by local laws. Management regularly evaluates whether foreign earnings 
are expected to be permanently reinvested. This evaluation requires judgment about the future operating and liquidity needs of 
the Company and its foreign subsidiaries. Changes in economic and business conditions, non-U.S. or U.S. tax laws could result 
in changes to these judgments and the need to record additional tax liabilities.

32

The Company has historically supported its liquidity needs through cash flows from operations. Management expects that the 
Company’s  (i)  current  level  of  cash,  cash  equivalents,  and  marketable  securities,  (ii)  current  and  forecasted  cash  flows  from 
operations, (iii) availability under existing funding arrangements, and (iv) access to capital in the capital markets will provide 
sufficient funds to support the Company’s operations, capital expenditures, investments, and debt obligations on both a short-term 
and long-term basis.

Revolving Credit Facility/Term Loan

On March 4, 2016, the Company entered into a five-year credit agreement (“Credit Agreement”) with a group of lenders for up 
to $700.0 million. The Credit Agreement consisted of an unsecured revolving credit facility (“Revolving Credit Facility”) of $575.0 
million and an unsecured term loan credit facility (“Term Loan”) of up to $125.0 million. In addition, the Company had the ability, 
from time to time, to increase the size of the Revolving Credit Facility and the Term Loan by up to an additional $150.0 million, 
in  the  aggregate,  in  each  case  in  minimum  increments  of  $25.0  million,  subject  to  certain  conditions  and  the  agreement  of 
participating lenders.

On October 13, 2017, the Company amended the Credit Agreement to increase the Revolving Credit Facility from $575.0 million 
to $700.0 million and increase the Term Loan from $125.0 million to $200.0 million and to extend the expiration date from March 
4, 2021 to October 13, 2022. The Credit Agreement also includes the option for the Company to increase the size of the Revolving 
Credit Facility and the Term Loan by up to an additional $300.0 million, in the aggregate, subject to the satisfaction of certain 
conditions set forth in the Credit Agreement. Term Loans may be made in up to two advances. The first advance of $125.0 million 
occurred on October 13, 2017 and the second advance of $75.0 million occurred on January 16, 2018. For the Term Loan, the 
Company is required to make quarterly principal payments of 1.25% of the original term loan ($2.5 million quarterly) through 
maturity, with the remaining balance due on October 13, 2022. The Company paid $10.0 million of principal payments on the 
Term Loan for the fiscal year ended December 28, 2019.

Outstanding borrowings under the Credit Agreement bear interest, at the Company’s option, at either LIBOR fixed for interest 
periods of one, two, three or six-month periods plus 1.00% to 2.00%, or at the bank’s Base Rate, as defined, plus 0.00% to 1.00%, 
based upon the Company’s Consolidated Leverage Ratio, as defined. The Company is also required to pay commitment fees on 
unused portions of the credit agreement ranging from 0.15% to 0.25%, based on the Consolidated Leverage Ratio, as defined in 
the agreement. The credit agreement includes representations, covenants and events of default that are customary for financing 
transactions of this nature. The effective interest rate on outstanding borrowings under the credit facility was 3.20% at December 28, 
2019.

As of December 28, 2019, the Company had no amounts outstanding in letters of credit and had available $353.4 million of 
borrowing capacity under the Revolving Credit Facility.

Net cash provided by operating activities was $245.3 million for 2019, compared to $331.8 million during 2018. The decrease in 
net cash provided by operating activities was primarily driven by lower earnings and higher working capital levels primarily due 
to the timing of supplier payments, payroll year-end cut off and higher annual incentive compensation payments in 2019.

Cash Flow from Investing Activities

Net cash used in investing activities was $56.5 million for 2019, compared to $382.3 million during 2018. Net cash used for the 
acquisition of IXYS was $306.5 million and $9.0 million for the acquisition of the remaining 38% outstanding common stock of 
Monolith in 2018. Capital expenditures were $61.9 million, representing a decrease of $12.9 million compared to 2018. The 
Company also received proceeds of $6.2 million in 2019 primarily as a result of the sale of a property within the Industrial segment.

Cash Flow from Financing Activities

Net cash used in financing activities was $146.3 million for 2019 compared to net cash provided by financing activities of $121.9 
million for 2018. The Company repurchased 579,916 shares of its common stock during fiscal 2019 totaling $95.0 million, but 
made payments of  $99.4 million related to settled share repurchases. The Company made payments of $10.0 million on the term 

34

Net cash provided by operating activities was $331.8 million for 2018, compared to $269.2 million during 2017. The increase in 
net cash provided by operating activities was primarily driven by higher earnings and favorable working capital management that 
more than offset higher payments related to cash taxes and acquisition and integration costs.

majority stake in Monolith for $14.2 million and the acquisition of U.S. Sensor for $24.3 million. Capital expenditures were $74.8 
million, representing an increase of $8.8 million compared to 2017. The Company also received proceeds of $9.6 million in 2018 
primarily as a result of the sale of a building.

Cash Flow from Financing Activities

million for 2017. The Company had $310.0 million of proceeds from the credit facility, term loan and senior notes payable partially 
offset by payments of $102.5 million on credit facility and the term loan in 2018 as compared to $149.4 million of proceeds from 
the credit facility, term loan and senior notes payable and $134.7 million of payments on credit facility and the term loan during

The  Company  has  Company-sponsored  defined  benefit  pension  plans  covering  employees  at  various  non-U.S.  subsidiaries 
including the U.K., Germany, the Philippines, China, Japan, Mexico, Italy and France. At December 28, 2019, the Company had 
a net unfunded status of $38.4 million. The Company expects to make approximately $2.3 million of contributions to the plans in 
2020. For additional information, see Note 11, Benefit Plans, of the Notes to Consolidated Financial Statements.

The Company has a non-qualified Supplemental Retirement and Savings Plan which provides additional retirement benefits for 
certain  management  employees  and  named  executive  officers  by  allowing  participants  to  defer  a  portion  of  their  annual 
compensation. As of December 28, 2019, there was $10.5 million of accrued compensation benefits included in Other long-term 
liabilities. For additional information, see Note 11, Benefit Plans, of the Notes to Consolidated Financial Statements.

As  of  December 28,  2019,  the  Company  recognized  various  accruals  related  to  employee  compensation  including  its  annual 
incentive program that are expected to be paid in 2020.

Due to the uncertainty with respect to the cash outflows, the preceding table excludes unrecognized tax benefits of $16.7 million. 
The Company does not expect to make significant payments of these liabilities within the next year. For additional information, 
see Note 14, Income Taxes, of the Notes to Consolidated Financial Statements.

37

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

The Company is exposed to market risk from changes in interest rates, foreign exchange rates and commodity prices.

Interest Rates Risk

The Company had $145.0 million in debt outstanding at December 28, 2019 related to the unsecured revolving credit facility and 
term loan. With variable interest rates, the Company is subject to future interest rate fluctuations in relation to these borrowings 
which could potentially have a negative impact on cash flows of the Company. A prospective increase of 100 basis points in the 
interest  rate  applicable  to  the  Company’s  outstanding  borrowings  under  its  credit  facility  would  result  in  an  increase  of 
approximately $1.5 million in annual interest expense. The Company is not party to any currency exchange or interest rate protection 
agreements as of December 28, 2019.

Foreign Exchange Rate Risk

The majority of the company’s operations consist of manufacturing and sales activities in foreign countries. The Company has 
operations in China, Germany, Mexico, Philippines, United Kingdom, Japan, Lithuania, Netherlands, Portugal, Singapore, South 
Korea, Spain, and the U.S. During 2019, sales to customers outside the U.S. were approximately 71% of total net sales. During 
2018,  sales  to  customers  outside  the  U.S.  were  approximately  70%  of  total  net  sales.  Substantially  all  sales  in  Europe  are 
denominated in euros and substantially all sales in the Asia-Pacific region are denominated in U.S. dollars, Chinese renminbi, 
Japanese yen, or Korean won.

The company’s foreign exchange exposures result primarily from inter-company loans, external borrowings, sale of products in 
foreign currencies, foreign currency denominated purchases, employee-related and other costs of running operations in foreign 
countries. The company’s most significant foreign currency exposures are to the euro, the Chinese renminbi, Mexican peso, and 
Philippine peso. Changes in foreign exchange rates could affect the company’s sales, costs, balance sheet values and earnings.

At December 28, 2019, the net value of the Company’s assets with exposure to foreign currency risk was approximately $147 
million, with the largest exposure being a Japanese yen denominated inter-company loan with a Euro functional currency subsidiary. 
The reduction in earnings from a hypothetical instantaneous 10% adverse change in quoted foreign currency spot rates applied to 
foreign currency sensitive asset instruments would be $15 million at December 28, 2019. At December 28, 2019, the net value of 
the Company’s liabilities with exposure to foreign currency risk was $369 million, with the largest exposure being U.S. Dollar 
denominated  inter-company  loans  with  a  Euro  functional  currency  subsidiary. The  reduction  in  earnings  from  a  hypothetical 
instantaneous 10% adverse change in quoted foreign currency spot rates applied to foreign currency sensitive liability instruments 
would be $37 million at December 28, 2019. As a result of the mix in currencies impacting the hypothetical 10% changes, the 
movements in some instruments would offset movements in other instruments reducing the hypothetical exposure to the Company.

Commodity Price Risk

The Company uses various metals in the manufacturing of its products, including copper, zinc, tin, gold, and silver. Prices of these 
commodities can rise and result in materially higher costs of producing our products. The Company believes it has adequate 
primary and secondary sources of supply for each of our key materials and that, in periods of rising prices, the Company expects 
to recover a majority of the increased cost in the form of higher selling prices. However, recoveries typically lag the effect of cost 
increases due to the nature of our markets.

The cost of oil has fluctuated dramatically over the past several years. Consequently, there is a risk that a return to high prices for 
oil and electricity in 2020 could have a significant impact on the Company’s transportation and utility expenses. While the Company 
is exposed to significant changes in certain commodity prices and foreign currency exchange rates, the Company actively monitors 
these exposures and may take various actions from time to time to mitigate any negative impacts of these exposures.

Report of Independent Registered Public Accounting Firm

Board of Directors and Shareholders

Littelfuse, Inc.

Opinion on the financial statements
We have audited the accompanying consolidated balance sheets of Littelfuse, Inc. (a Delaware corporation) and subsidiaries (the 
“Company”) as of December 28, 2019 and December 29, 2018, the related consolidated statements of net income, comprehensive 
income, equity, and cash flows for each of the three years in the period ended December 28, 2019, and the related notes and 
financial statement schedule included under Item 15(a) (collectively referred to as the “financial statements”). In our opinion, the 
financial statements present fairly, in all material respects, the financial position of the Company as of December 28, 2019 and 
December 29, 2018, and the results of its operations and its cash flows for each of the three years in the period ended December 28, 
2019, in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(“PCAOB”), the Company’s internal control over financial reporting as of December 28, 2019, based on criteria established in 
the  2013  Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission (“COSO”), and our report dated February 21, 2020, expressed an unqualified opinion.

Change in accounting principle
As discussed in Note 1 to the consolidated financial statements, the Company has changed its method of accounting for operating 
leases as of December 30, 2018 due to the adoption of ASU 2016-02, Leases (Topic 842).

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

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error 
or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether 
due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting 
principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial 
statements. We believe that our audits provide a reasonable basis for our opinion.

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

Goodwill Impairment Analysis 
The  Company’s  consolidated  goodwill  balance  was  $820.6  million  as  of  December  28,  2019. As  described  in  Note  1  to  the 
consolidated  financial  statements,  the  Company  evaluates  goodwill  for  impairment  at  the  reporting  unit  level  annually  and 
performed  quantitative  goodwill  impairment  assessment  for  each  of  its  seven  reporting  units.  The  quantitative  impairment 
assessment involves the comparison of the fair value of a reporting unit to its carrying amount. The Company used a weighting 
of the income and market approaches to determine the fair value of the reporting unit. 

We  identified  the  goodwill  impairment  analysis  as  a  critical  audit  matter  for  certain  reporting  units  because  management's 
quantitative goodwill impairment test involved a high degree of auditor judgment due to the significant estimation required to 

40

determine the fair value of the reporting unit. In particular, the fair value estimate was sensitive to significant assumptions, such 
as forecasted revenues, operating income margins, long-term discount rate, perpetual growth rate, and estimated valuation multiples.

Our audit procedures related to the goodwill impairment analysis of certain reporting units included the following, among others. 
We tested the design and operating effectiveness of key controls over the Company's goodwill impairment assessment process 
including review of the valuation model and significant assumptions used.  We tested the significant assumptions discussed above 
by  assessing  the  reasonableness  of  management’s  forecasts  compared  to  current  results  and  forecasted  industry  trends.  We 
performed sensitivity analyses of certain assumptions to evaluate changes in the fair value that would result from changes in the 
assumptions. With the assistance of our valuation specialists, we evaluated the selection of the long-term discount rate and perpetual 
growth rate, including testing the underlying source information and the mathematical accuracy of the calculations by developing 
a  range  of  independent  estimates  and  comparing  those  to  the  rates  selected  by  management. We  also  involved  our  valuation 
specialists to evaluate the market approach, including evaluating the reasonableness of estimated valuation multiples.

Report of Independent Registered Public Accounting Firm

Board of Directors and Shareholders

Littelfuse, Inc.

Opinion on internal control over financial reporting
We have audited the internal control over financial reporting of Littelfuse, Inc. (a Delaware corporation) and subsidiaries (the 
“Company”) as of December 28, 2019, based on criteria established in the 2013 Internal Control—Integrated Framework issued 
by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). In our opinion, the Company maintained, 
in all material respects, effective internal control over financial reporting as of December 28, 2019, based on criteria established 
in the 2013 Internal Control—Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(“PCAOB”), the consolidated financial statements of the Company as of and for the year ended December 28, 2019, and our report 
dated February 21, 2020 expressed an unqualified opinion on those financial statements.

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 Report on Internal 
Control over Financial Reporting (“Management’s Report”). 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.

1. Summary of Significant Accounting Policies and Other Information

Nature of Operations 

Littelfuse, Inc. and subsidiaries (the “Company”) is a global manufacturer of leading technologies in circuit protection, power 
control and sensing. The company's  products are found in automotive and commercial vehicles, industrial applications, data and 
telecommunications,  medical  devices,  consumer  electronics  and  appliances.  With  its  broad  product  portfolio  of  fuses, 
semiconductors, polymers, ceramics, relays and sensors, and extensive global infrastructure, the Company’s worldwide associates 
partner with its customers to design, manufacture and deliver innovative, high-quality solutions for a safer, greener and increasingly 
connected world.

Fiscal Year 

References herein to “2019”, “fiscal 2019” or “fiscal year 2019” refer to the fiscal year ended December 28, 2019. References 
herein to “2018”, “fiscal 2018” or “fiscal year 2018” refer to the fiscal year ended December 29, 2018. References herein to “2017”, 
“fiscal 2017” or “fiscal year 2017” refer to the fiscal year ended December 30, 2017. The Company operates on a 52-53 week 
fiscal year (4-4-5 basis) ending on the Saturday closest to December 31. 

Basis of Presentation 

The Consolidated Financial Statements include the accounts of Littelfuse, Inc. and its subsidiaries. All significant intercompany 
accounts and transactions have been eliminated. The Company’s Consolidated Financial Statements were prepared in accordance 
with generally accepted accounting principles in the United States of America and include the assets, liabilities, sales and expenses 
of all wholly-owned subsidiaries and majority-owned subsidiaries over which the Company exercises control.

Use of Estimates 

The process of preparing financial statements in conformity with generally accepted accounting principles in the United States of 
America requires management to make estimates and assumptions that affect the amounts of assets and liabilities at the date of 
the Consolidated Financial Statements, and the reported amounts of revenues and expenses and the accompanying notes. The 
Company evaluates and updates its assumptions and estimates on an ongoing basis and may employ outside experts to assist in 
its evaluation, as considered necessary. Actual results could differ from those estimates.

Cash Equivalents

All  highly  liquid  investments,  with  an  original  maturity  of  three  months  or  less  when  purchased,  are  considered  to  be  cash 
equivalents.

Short-Term and Long-Term Investments

As  of  December 28,  2019,  the  Company  has  an  investment  in  Polytronics Technology  Corporation  Ltd.  (“Polytronics”). The 
Company’s Polytronics shares held at the end of fiscal 2019 and 2018 represent approximately 7.2% of total Polytronics shares 
outstanding. The Polytronics investment is carried at fair value. The fair value of the Polytronics investment was €11.6 million
(approximately $12.8 million) at December 28, 2019 and €8.9 million (approximately $10.2 million) at December 29, 2018.

As a result of the Company’s acquisition of IXYS, the Company has equity ownerships in various investments that are accounted 
for under the equity method. The Company owns 45% of the outstanding equity of Powersem GmbH, a module manufacturer 
based in Germany, approximately 19% of the outstanding equity of EB Tech Ltd., a company with expertise in radiation technology 
based in South Korea, and approximately 24% of the outstanding common shares of Automated Technology, Inc., a supplier located 
in the Philippines that provides assembly and test services. All equity-level investments are less than majority owned. The Company 
recognized  $0.6  million  in  losses  and  $0.7  million  in  gains  from  its  equity  method  investments  for  the  fiscal  years  ended 
December 28, 2019 and December 29, 2018, respectively. The balance of equity method investments was $11.1 million  and $11.6 
million  as  of  the  fiscal  years  ended  December 28,  2019  and  December  29,  2018,  respectively.  See  Note  18,  Related  Party 
Transactions, for further discussion.

The balance of the Company's investments accounted for under the cost method was $0.4 million and $7.9 million for the fiscal 
years ended December 28, 2019 and December 29, 2018, respectively. During the twelve months ended December 28, 2019, 

48

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

the Company recorded impairment charges of $7.3 million in Other income, net in the Consolidated Statements of Net Income 
to adjust these certain investments to their estimated fair value of $0.4 million. See Note 10, Fair Value of Assets and 
Liabilities, for further discussion.

The Company has investments related to its non-qualified Supplemental Retirement and Savings Plan. The Company maintains 
accounts for participants through which participants make investment elections. The investment securities are subject to the 
claims of the Company’s creditors. The investment securities are all mutual funds. The investment securities are measured at 
net asset value. As of December 28, 2019 and December 29, 2018, the investment securities balance was $10.5 million and $9.1 
million, respectively, related to the plan and are included in Other assets on the Consolidated Balance Sheets.

Trade Receivables

The Company performs credit evaluations of customers’ financial condition and generally does not require collateral. Credit losses 
are provided for in the financial statements based upon specific knowledge of a customer’s inability to meet its financial obligations 
to the Company. Historically, credit losses have consistently been within management’s expectations and have not been a material 
amount. A receivable is considered past due if payments have not been received within agreed upon invoice terms. Write-offs are 
recorded at the time a customer receivable is deemed uncollectible.

The Company also maintains allowances against trade receivables for the settlement of rebates and sales discounts to customers. 
These allowances are based upon specific customer sales and sales discounts as well as actual historical experience.

Inventories

Inventories are stated at the lower of cost or net realizable value, which approximates current replacement cost. Cost is principally 
determined using the first-in, first-out method. The Company maintains excess and obsolete reserves against inventory to reduce 
the carrying value to the expected net realizable value. These reserves are based upon a combination of factors including historical 
sales volume, market conditions, lower of cost or market analysis and expected realizable value of the inventory.

Property, Plant, and Equipment

Land, buildings, and equipment are carried at cost. Depreciation is calculated using the straight-line method with useful lives of 
21 years for buildings, three to ten years for equipment, seven years for furniture and fixtures, five years for tooling and three 
years  for  computer  equipment.  Leasehold  improvements  are  depreciated  over  the  lesser  of  their  useful  life or  the  lease  term. 
Maintenance and repair costs are charged to expense as incurred. Major overhauls that extend the useful lives of existing assets 
are capitalized.

Goodwill

The Company annually tests goodwill for impairment on the first day of its fiscal fourth quarter, or more frequently if an event 
occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value.

The Company compares each reporting unit’s fair value, estimated based on comparable company market valuations and expected 
future discounted cash flows to be generated by the reporting unit, to its carrying value. The results of the goodwill impairment 
test as of September 30, 2019 indicated that the estimated fair values for each of the seven reporting units exceeded their respective 
carrying values. As of the most recent annual test conducted on September 30, 2019, the Company noted that the excess of fair 
value over the carrying value, was 217%, 42%, 137%, 213%, 40%, 89%, and 268% for its reporting units; Electronics-Passive 
Products and Sensors, Electronics-Semiconductor, Passenger Car Products, Commercial Vehicle Products, Automotive Sensors, 
Relays, and Power Fuse, respectively. Relatively small changes in the Company’s key assumptions would not have resulted in any 
reporting units failing the goodwill impairment test. See Note 5, Goodwill and Other Intangible Assets, for additional information.

The Company also performs an interim review for indicators of impairment each quarter to assess whether an interim impairment 
review is required for any reporting unit. As part of its interim reviews, management analyzes potential changes in the value of 
individual reporting units based on each reporting unit’s operating results for the period compared to expected results as of the 
prior year’s annual impairment test. In addition, management considers how other key assumptions, including discount rates and 
expected long-term growth rates, used in the last annual impairment test, could be impacted by changes in market conditions and 
economic events. Based on the interim assessments as of December 28, 2019, management concluded that no events or changes 
in circumstances indicated that it was more likely than not that the fair value for any reporting unit had declined below its carrying 
value.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Long-Lived Assets

Customer relationships, trademarks and tradenames are amortized using the straight-line method over estimated useful lives that 
have a range of 5 to 20 years. Patents, licenses and software are amortized using the straight-line method or an accelerated method 
over estimated useful lives that have a range of 5 to 17 years. The distribution networks are amortized on either a straight-line or 
accelerated basis over estimated useful lives that have a range of 4 to 10 years.  Land use rights are amortized using the straight-
line method over 50 years which is the term of the land use rights.

The Company assesses potential impairments to its long-lived assets if events or changes in circumstances indicate that the carrying 
amount of an asset may not be recoverable. An impaired asset is written down to its estimated fair value based upon the most 
recent information available. Estimated fair market value is generally measured by discounting estimated future cash flows. Long-
lived assets, other than goodwill and other intangible assets, that are held for sale are recorded at the lower of carrying value or 
the fair market value less the estimated cost to sell.

Environmental Liabilities

Environmental liabilities are accrued based on engineering studies estimating the cost of remediating sites. Expenses related to 
on-going maintenance of environmental sites are expensed as incurred. If actual or estimated probable future losses exceed the 
Company’s recorded liability for such claims, the Company would record additional charges during the period in which the actual 
loss or change in estimate occurred.

Pension and Other Post-retirement Benefits

The Company records annual income and expense amounts relating to its pension and post-retirement benefits plans based on 
calculations  which  include  various  actuarial  assumptions  including  discount  rates,  expected  long-term  rates  of  return  and 
compensation increases. The Company reviews its actuarial assumptions on an annual basis as of the fiscal year-end balance sheet 
date (or more frequently if a significant event requiring remeasurement occurs) and modifies the assumption based on current rates 
and trends when it is appropriate to do so. The effects of modifications are recognized immediately on the Consolidated Balance 
Sheets, but are generally amortized into operating earnings over future periods, with the deferred amount recorded in accumulated 
other comprehensive income (loss). The Company believes that the assumptions utilized in recording its obligations under its plans 
are reasonable based on its experience, market conditions and input from its actuaries and investment advisors.

Revenue Recognition

Adoption

On  December  31,  2017,  the  Company  adopted  new  guidance  on  revenue  from  contracts  with  customers  using  the  modified 
retrospective method. The adoption did not have a significant impact on the Company’s consolidated financial statements.

See Note 16, Segment Information, for net sales by segment and countries.

The Company recognizes revenue on product sales in the period in which the Company satisfies its performance obligation and 
control of the product is transferred to the customer. The Company’s sales arrangements with customers are predominately short 
term in nature and generally provide for transfer of control at the time of shipment as this is the point at which title and risk of loss 
of the product transfers to the customer. At the end of each period, for those shipments where title to the products and the risk of 
loss and rewards of ownership do not transfer until the product has been received by the customer, the Company adjusts revenues 
and cost of sales for the delay between the time that the products are shipped and when they are received by the customer. The 
amount of revenue recorded reflects the consideration to which the Company expects to be entitled in exchange for goods and 
may include adjustments for customer allowance, rebates and price adjustments. The Company’s distribution channels are primarily 
through direct sales and independent third-party distributors.

The Company  has  elected the  practical expedient under Accounting  Standards Codification ("ASC")  340-40-25-4 to  expense 
commissions when incurred as the amortization period of the commission asset the Company would have otherwise recognized 
is less than one year.

Revenue and Billing

The Company generally accepts orders from customers through receipt of purchase orders or electronic data interchange based 
on written sales agreements and purchasing contracts. Contract pricing and selling agreement terms are based on market factors, 
costs, and competition. Pricing is often negotiated as an adjustment (premium or discount) from the Company’s published price 
lists. The  customer  is  invoiced  when  the  Company’s  products  are  shipped  to  them  in  accordance  with  the  terms  of  the  sales 
agreement. As the Company’s standard payment terms are less than one year, the Company has elected the practical expedient 
under ASC 606-10-32-18 to not assess whether a contract has a significant financing component. The Company also elected the 
practical expedient provided in ASC 606-10-25-18B to treat all product shipping and handling activities as fulfillment activities, 
and therefore recognize the gross revenue associated with the contract, inclusive of any shipping and handling revenue. This is 
similar to the Company’s prior practice and therefore the effect of the new guidance is immaterial.

Ship and Debit Program

Some of the terms of the Company’s sales agreements and normal business conditions provide customers (distributors) the ability 
to receive price adjustments on products previously shipped and invoiced. This practice is common in the industry and is referred 
to as a “ship and debit” program. This program allows the distributor to debit the Company for the difference between the distributors’ 
contracted price and a lower price for specific transactions. Under certain circumstances (usually in a competitive situation or large 
volume opportunity), a distributor will request authorization for pricing allowances to reduce its price. When the Company approves 
such a reduction, the distributor is authorized to “debit” its account for the difference between the contracted price and the lower 
approved price. The Company establishes reserves for this program based on historic activity, electronic distributor inventory 
levels and actual authorizations for the debit and recognizes these debits as a reduction of revenue.

Return to Stock 

The Company has a return to stock policy whereby certain customers, with prior authorization from the Company's management, 
can return previously purchased goods for full or partial credit. The Company establishes an estimated allowance for these returns 
based on historic activity. Sales revenue and cost of sales are reduced to anticipate estimated returns.

51

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Volume Rebates

The Company offers volume-based sales incentives to certain customers to encourage greater product sales. If customers achieve 
their specific quarterly or annual sales targets, they are entitled to rebates. The Company estimates the projected amount of rebates 
that will be achieved by the customer and recognizes this estimated cost as a reduction to revenue as products are sold.

Allowance for Doubtful Accounts

The Company evaluates the collectability of its trade receivables based on a combination of factors. The Company regularly 
analyzes its significant customer accounts and, when the Company becomes aware of a specific customer’s inability to meet its 
financial obligations, the Company records a specific reserve for bad debt to reduce the related receivable to the amount the 
Company reasonably believes is collectible. The Company also records allowances for all other customers based on a variety of 
factors including the length of time the receivables are past due, the financial health of the customer, macroeconomic considerations 
and past experience. Historically, the allowance for doubtful accounts has been adequate to cover bad debts. If circumstances 
related to specific customers change, the estimates of the recoverability of receivables could be further adjusted.

Advertising Costs

The Company expenses advertising costs as incurred, which amounted to $2.7 million, $2.8 million, and $2.9 million in fiscal 
years 2019, 2018 and 2017, respectively, and are included as a component of selling, general, and administrative expenses.

Shipping and Handling Fees and Costs

Amounts billed to customers related to shipping and handling is classified as revenue. Costs incurred for shipping and handling 
of $11.0 million, $12.3 million, and $10.9 million in fiscal years 2019, 2018, and 2017, respectively, are classified in selling, 
general, and administrative expenses.

Foreign Currency Translation / Remeasurement

The Company’s foreign subsidiaries use the local currency or the U.S. dollar as their functional currency, as appropriate. Assets 
and liabilities are translated using exchange rates at the balance sheet date, and revenues and expenses are translated at weighted 
average rates. The amount of foreign currency gain or loss from remeasurement recognized in the income statement was a loss of 
$5.2 million in fiscal year 2019, a gain of $0.9 million in fiscal year 2018, and a loss of $2.4 million in fiscal year 2017. Adjustments 
from the translation process are recognized in “Shareholders’ equity” as a component of “Accumulated other comprehensive 
income/ (loss).”

Stock-Based Compensation

The Company recognizes compensation expense for the cost of awards of equity compensation using a fair value method. Benefits 
of tax deductions in excess of recognized compensation expense are reported as operating cash flows. See Note 12, Stock-Based 
Compensation, for additional information on stock-based compensation.

Coal Mining Liability

Included in other long-term liabilities is an accrual related to former coal mining operations at Littelfuse GmbH (formerly 
known as Heinrich Industries, AG) for the amounts of €0.6 million ($0.7 million) and €1.1 million ($1.3 million) at 
December 28, 2019 and December 29, 2018, respectively. Management, in conjunction with an independent third-party, 
performs an annual evaluation of the former coal mining operations in order to develop an estimate of the probable future 
obligations in regard to remediating the dangers (such as a shaft collapse) of abandoned coal mine shafts in the former coal 
mining operations. Management accrues for costs associated with such remediation efforts based on management's best 
estimate when such costs are probable and reasonably able to be estimated. The ultimate determination can only be done after 
respective investigations because the concrete conditions are mostly unknown at this time.

Other Income, Net

Other income, net generally consists of interest income, royalties, change in fair value of available-for-sale securities, pension 
non-service costs and other non-operating expense (income).

52

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Income Taxes

The Company accounts for income taxes using the liability method. Deferred taxes are recognized for the future effects of temporary 
differences between financial and income tax reporting using enacted tax rates in effect for the years in which the differences are 
expected to reverse. The Company recognizes deferred taxes for temporary differences, operating loss carryforwards, and tax 
credit and other tax attribute carryforwards (excluding carryforwards where usage has been determined to be remote). Deferred 
tax assets are reduced by a valuation allowance if it is more likely than not that some portion, or all, of the deferred tax assets will 
not be realized. U.S. state and non-U.S. income taxes are provided on the portion of non-U.S. income that is expected to be remitted 
to the U.S. and be taxable (and non-U.S. income taxes are provided on the portion of non-U.S. income that is expected to be 
remitted to an upper-tier non-U.S. entity). Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and 
rates on the date of enactment.

Deferred U.S. income taxes and non-U.S. taxes are not provided on the excess of the investment value for financial reporting over 
the tax basis of investments in those non-U.S. subsidiaries for which such excess is considered to be permanently reinvested in 
those operations. Management regularly evaluates whether non-U.S. earnings are expected to be permanently reinvested. This 
evaluation requires judgment about the future operating and liquidity needs of the Company and its non-U.S. subsidiaries.  Changes 
in economic and business conditions, non-U.S. or U.S. tax laws, or the Company’s financial situation could result in changes to 
these judgments and the need to record additional tax liabilities.

The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will 
be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized 
in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood 
of being realized upon ultimate settlement.

On December 22, 2017, the U.S. enacted legislation commonly referred to as the Tax Cuts and Jobs Act (the "Tax Act"). Among 
other things, the Tax Act reduces the U.S. corporate federal income tax rate from 35% to 21%, adds base broadening provisions 
which limit deductions and address excessive international tax planning, imposes a one-time tax (the “Toll Charge”) on accumulated 
earnings of certain non-U.S. subsidiaries and enables repatriation of earnings of non-U.S. subsidiaries free of U.S. federal income 
tax. Other than the Toll Charge (which, except for the IXYS impact, was applicable to the Company for 2017), the provisions are 
generally applicable to the Company in 2018 and beyond.

In accordance with the guidance provided in SEC Staff Accounting Bulletin (“SAB”) No. 118, in the fourth quarter of 2017 the 
Company recorded a charge of $47.0 million as a provisional reasonable estimate of the impact of the Tax Act, including $49.0 
million for the Toll Charge net of $2.0 million for other net tax benefits. In the fourth quarter of 2018, within the measurement 
period outlined in SAB No. 118, the Company finalized its estimates of the impact of the Tax Act as of December 30, 2017 and 
recorded a charge of $3.2 million, including $2.3 million for the Toll Charge and $0.9 million for the net impact of other items. 
In addition, the Company recorded $7.0 million for the Toll Charge associated with IXYS as part of the IXYS acquisition purchase 
price allocation. This was reflected in the opening balance sheet as an increase to goodwill and other long-term liabilities.

Although certain administrative guidance has been issued, including final and proposed regulations, the appropriate application 
of many provisions of the Tax Act remain uncertain. The Company used its best judgment as to the application of these provisions 
in determining its final estimates of the impact of the Tax Act as of December 30, 2017, the Toll Charge associated with the IXYS 
acquisition as well as the Company’s income tax expense for the fiscal years ended December 28, 2019 and December 29, 2018. 
Adjustments to income tax expense may be necessary in future periods if provisions of the Tax Act, and their interaction with other 
provisions of the U.S. Internal Revenue Code, are interpreted differently than interpretations made by the Company, whether 
through issuance of additional administrative guidance, or through further review of the Tax Act by the Company and its advisors. 

The Company has elected to pay the 2017 Littelfuse Toll Charge over the eight-year period prescribed by the Tax Act. The long-
term portion of this Toll Charge which remains payable as of December 28, 2019, totaling $23.8 million, is included in Other long-
term liabilities, and the anticipated 2020 annual installment payment of $3.0 million is included in Accrued income taxes, on the 
Consolidated Balance Sheet as of December 28, 2019. The Company did not elect to pay the 2018 IXYS Toll Charge over the 
eight year period provided by the Tax Act and therefore there is no long-term portion of this Toll Charge which remains payable 
as of December 28, 2019. 

One of the base broadening provisions of the Tax Act is commonly referred to as the “GILTI” provisions. In accordance with 
guidance issued by the FASB staff, the Company has adopted an accounting policy to treat any GILTI inclusions as a period cost 
if and when incurred. Thus, for the fiscal years ended December 28, 2019 and December 29, 2018, deferred taxes were computed 

53

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

without consideration of the possible future impact of the GILTI provisions, and any current year impact was recorded as a part 
of the current portion of income tax expense.

Fair Value Measurements

Certain assets and liabilities are required to be recorded at fair value on a recurring basis. Fair value is determined based on the 
exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous 
market for the asset or liability in an orderly transaction between market participants. The Company records the fair value of its 
available-for-sale securities and pension plan assets on a recurring basis. Assets measured at fair value on a nonrecurring basis 
include long-lived assets held and used, long-lived assets held for sale, goodwill and other intangible assets. The fair value of cash 
and cash equivalents, accounts receivable, short-term debt and accounts payable approximate their carrying values. The three-tier 
value hierarchy, which prioritizes valuation methodologies based on the reliability of the inputs, is:

Level 1 – Valuations based on quoted prices for identical assets and liabilities in active markets.

Level 2 – Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for 
similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that 
are not active, or other inputs that are observable or can be corroborated by observable market data.

Level 3 – Valuations based on unobservable inputs reflecting the Company’s own assumptions, consistent with reasonably 
available assumptions made by other market participants.

Recently Adopted Accounting Standards

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, 
"Leases" (Topic 842), ("ASC 842"). This ASU requires lessees to recognize, on the balance sheet, assets and liabilities for the 
rights and obligations created by leases of greater than twelve months. 

The Company adopted the standard on December 30, 2018 using the alternative modified retrospective transition method provided 
in ASU No. 2018-11, "Leases (Topic 842): Target Improvements." Under this method, the Company recorded a cumulative-effect 
adjustment as of December 30, 2018 and did not record any retrospective adjustments to comparative periods to reflect the adoption 
of ASC 842. The new standard provides a number of optional practical expedients in transition. The Company has elected the 
‘package  of  practical  expedients’  which  permits  us  not  to  reassess  under  the  new  standard  our  prior  conclusions  about  lease 
identification, lease classification and initial direct costs. The Company has not elected the use-of-hindsight. Adoption of ASC 
842 resulted in the recognition of operating lease right-of-use assets ("ROU") net of deferred rent of $26.1 million and lease 
liabilities of $29.4 million, as of December 30, 2018 for operating leases on its Consolidated Balance Sheets, with no impact to 
the Company's Consolidated Statements of Net Income and Consolidated Statements of Cash Flow. See Note 7, Lease Commitments,
for further discussion.

In  February  2018,  the  FASB  issued ASU  No.  2018-02  “Income  Statement—Reporting  Comprehensive  Income  (Topic  220): 
Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income,” which permits the reclassification of 
tax effects stranded in accumulated other comprehensive income to retained earnings as a result of the Tax Act. The standard also 
requires entities to disclose whether or not they elected to reclassify the tax effects related to the Tax Act as well as their policy 
for releasing income tax effects from accumulated other comprehensive income. The standard allows the option of applying either 
a retrospective adoption, meaning the standard is applied to all periods in which the effect of the Tax Act is recognized, or applying 
the amendments in the period of adoption, meaning an adjustment is made to shareholder’s equity as of the beginning of the 
reporting period. The Company adopted the new standard on December 30, 2018. The adoption of this guidance did not have a 
material effect on the Company's Consolidated Financial Statements.

In January 2018, the FASB released guidance on the accounting for the GILTI provisions of the 2017 U.S. Tax Act. The GILTI 
provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The guidance 
indicates that either accounting for deferred taxes related to GILTI inclusions or treating any taxes on GILTI inclusions as period 
cost are both acceptable methods subject to an accounting policy election. The Company has adopted an accounting policy to treat 
any GILTI inclusions as a period cost if and when incurred. Thus, for the year ended December 29, 2018, deferred taxes were 
computed without consideration of the possible future impact of the GILTI provisions, and any current year impact was recorded 
as a part of the current portion of income tax expense.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

In March 2017, the FASB issued  ASU No. 2017-07 “Compensation-Retirement Benefits (Topic 715): Improving the Presentation 
of Net Periodic Pension Cost and Net Periodic Post-Retirement Benefit Cost,” which changed the presentation of net periodic 
pension and post-retirement benefit cost (net benefit cost) within the consolidated Statements of Net Income. Under the previous 
guidance, net benefit cost was reported as an employee cost within operating income. The amendment required the bifurcation of 
net benefit cost, with the service cost component to be presented with other employee compensation costs in operating income 
while the other components will be reported separately outside of income from operations. ASU No. 2017-07 was effective for 
the first quarter of 2018 with the Company adopting the new standard on December 31, 2017.

In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments-Recognition and Measurement of Financial Assets 
and Financial Liabilities” which addressed certain aspects of the recognition, measurement, presentation and disclosure of financial 
instruments. The ASU requires the Company to recognize any changes in the fair value of certain equity investments in net income. 
Previously these changes were recognized in other comprehensive income ("OCI"). The Company adopted the new standard on 
December 31, 2017, on a modified retrospective basis, recognizing the cumulative effect as a $9.8 million increase to retained 
earnings. As a result of the adoption of the new standard and change in fair value of our equity investments, for the fiscal year 
ended December 29, 2018, the Company recognized an unrealized loss of $0.7 million in Other income, net in the Consolidated 
Statements of Net Income.

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” (Topic 606) which supersedes the 
revenue recognition requirements in ASC 605, “Revenue Recognition.” This ASU provides a single comprehensive model for 
entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition 
guidance. The guidance permits two implementation approaches, one requiring retrospective application of the new standard with 
restatement of prior years and one requiring prospective application of the new standard with disclosure of results under old 
standards. The Company adopted the new standard on December 31, 2017 using the modified retrospective method, however, no 
adjustment to retained earnings was needed. The new guidance did not have a material effect on the Company’s Consolidated 
Statements of Net Income. See the Revenue Recognition section above for further discussion.

In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes” (Topic 740). This ASU update requires entities to recognize 
the income tax consequences of many intercompany asset transfers at the transaction date. The seller and buyer will immediately 
recognize the current and deferred income tax consequences of an intercompany transfer of an asset other than inventory. The tax 
consequences were previously deferred. The Company adopted the new standard on December 31, 2017 and it did not have a 
material impact.

Recently Issued Accounting Standards

In June 2016, the FASB issued ASU 2016- 13, “Financial Instruments- Credit Losses (Topic 326), Measurement of Credit Losses 
on Financial Instruments.” The standard modifies the measurement approach for credit losses on financial instruments, including 
trade receivables, from an incurred loss method to a current expected credit loss method (“CECL”). The standard requires the 
measurement of expected credit losses to be based on relevant information, including historical experience, current conditions and 
a forecast that is supportable. The standard is effective for fiscal years beginning after December 15, 2019, including interim 
periods within those fiscal years; early adoption is permitted. The standard must be adopted by applying a cumulative adjustment 
to retained earnings. The Company anticipates adopting the standard in the first quarter of 2020, although it does not expect a 
material impact to the Company’s Consolidated Financial Statements.

In August 2018, the FASB issued ASU No. 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to 
the Disclosure Requirements for Fair Value Measurement." ASU 2018-13 modified the disclosure requirements in Topic 820, "Fair 
Value Measurement," based on the FASB Concepts Statement, "Conceptual Framework for Financial Reporting - Chapter 8: Notes 
to Financial Statements," including consideration of costs and benefits. The guidance is effective for fiscal years beginning after 
December 15, 2019 and for interim periods within those fiscal years, with early adoption permitted. The company is currently 
evaluating the potential effects of this guidance on its Consolidated Financial Statements.

In August 2018, the FASB issued ASU No. 2018-14 "Disclosure Framework - Changes to the Disclosure Requirements for Defined 
Benefit Plans," which amends ASC 715-20, Compensation - Retirement Benefits - Defined Benefit Plans - General. The amended 
guidance modifies the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans 
by removing and adding certain disclosures for these plans. The eliminated disclosures include (a) the amounts in  OCI expected 
to be recognized in net periodic benefit costs over the next fiscal year, and (b) the effects of a one percentage point change in 
assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for post-retirement health care 
benefits. Additional disclosures include descriptions of significant gains and losses affecting the benefit obligation for the period.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

This guidance will be effective for financial statements issued for fiscal years ending after December 15, 2020. The adoption of 
this guidance will modify our disclosures but will not have a material effect on the Company's Consolidated Financial Statements.

In August 2018, the FASB issued ASU No. 2018-15, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): 
Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a 
consensus of the FASB Emerging Issues Task Force).” ASU 2018-15 aligns the requirements for capitalizing implementation costs 
incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred 
to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The guidance 
is effective for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years, with early adoption 
permitted. The Company is currently evaluating this guidance on its Consolidated Financial Statements.

In December 2019, the FASB issued ASU No. 2019-12, "Income Taxes (Topic 740) - Simplifying the Accounting for Income 
Taxes" as part of its initiative to reduce complexity in the accounting standards.  The guidance is effective for fiscal years beginning 
after December 15, 2021 with early adoption permitted.  The Company is currently evaluating this guidance on its Consolidated 
Financial  Statements,  The  Company  does  not  expect  material  effect  from  the  adoption  of  this  guidance  on  the  Company's 
Consolidated Financial Statements.

2. Acquisitions

The Company accounts for acquisitions using the acquisition method in accordance with ASC 805, “Business Combinations,” in 
which assets acquired and liabilities assumed are recorded at fair value as of the date of acquisition. The operating results of the 
acquired business are included in the Company’s Consolidated Financial Statements from the date of the acquisition.

IXYS Corporation

On January 17, 2018, the Company acquired IXYS Corporation (“IXYS”), a global pioneer in the power semiconductor and 
integrated circuit markets with a focus on medium to high voltage power semiconductors across the industrial, communications, 
consumer and medical markets. IXYS has a broad customer base, serving more than 3,500 customers through its direct sales force 
and global distribution partners. The acquisition of IXYS is expected to accelerate the Company’s growth across the power control 
market driven by IXYS’s extensive power semiconductor portfolio and technology expertise. With IXYS, the Company will be 
able to diversify and expand its presence within industrial electronics markets, leveraging the strong IXYS industrial OEM customer 
base. The Company also expects to increase long-term penetration of its power semiconductor portfolio in automotive markets, 
expanding its global content per vehicle.

Upon completion of the acquisition, at IXYS stockholders’ election and subject to proration, each share of IXYS common stock, 
par  value  $0.01  per  share,  owned  immediately  prior  to  the  effective  time  were  canceled  and  extinguished  and  automatically 
converted into the right to receive: (i) $23.00 in cash (subject to applicable withholding tax), without interest (referred to as the 
cash consideration), or (ii) 0.1265 of a share of common stock, par value $0.01 per share, of Littelfuse (referred to as the stock 
consideration).  IXYS  stockholders  received  cash  in  lieu  of  any  fractional  shares  of  Littelfuse  common  stock  that  the  IXYS 
stockholders would otherwise have been entitled to receive. Additionally, each outstanding option to purchase shares of IXYS 
common stock granted under an IXYS equity plan were assumed by Littelfuse and converted into an option to acquire (i) a number 
of shares of Littelfuse common stock equal to the number of shares of IXYS common stock subject to such option immediately 
prior to the effective time multiplied by 0.1265, rounded down to the nearest whole share, with (ii) an exercise price per share of 
Littelfuse common stock equal to the exercise price of such IXYS stock option immediately prior to the effective time divided by 
0.1265, rounded up to the nearest whole cent.

Based on the $207.5 per share opening price of Littelfuse common stock on January 17, 2018, the consideration IXYS stockholders 
received in exchange of their IXYS common stock in the acquisition had a value of $814.8 million comprised of $380.6 million
of cash and $434.2 million of Littelfuse stock. In addition to the consideration transferred related to IXYS common stock, the 
value of consideration transferred, and included in the purchase price, related to IXYS stock options that were converted to Littelfuse 
stock options, or cash settled, had a value of $41.7 million. As a result, total consideration was valued at $856.5 million.

The total purchase price of $856.5 million has been allocated to assets acquired and liabilities assumed, as of the completion of 
the acquisition, based on estimated fair values. The following table summarizes the purchase price allocation of the fair value of 
assets acquired and liabilities assumed in the IXYS acquisition:

Approximately  $49.1  million  of  net  receivables  was  included  in  IXYS’s  current  assets, All  IXYS  goodwill,  other  assets  and 
liabilities were recorded in the Electronics segment and primarily reflected in the Americas and European geographic areas. The 
goodwill  resulting  from  this  acquisition  consists  largely  of  the  Company’s  expected  future  product  sales  and  synergies  from 
combining IXYS’s products and technology with the Company’s existing electronics product portfolio. Goodwill resulting from 
the IXYS acquisition is not expected to be deductible for tax purposes. The Company recorded $7.0 million for the Toll Charge 
associated with IXYS as part of the IXYS acquisition purchase price allocation (this reflects a reduction of $1.0 million recorded 
in the fourth quarter of 2018 and $2.0 million recorded in the third quarter of 2018 as a consequence of revisions to the Company’s 
original estimates. For additional information, see Note 14, Income Taxes. As a result of the Company completing its fair value 
analysis, in the fourth quarter of 2018, the company recorded a reduction of $2.6 million in certain investments held by IXYS. 

Included in the Company’s Consolidated Statements of Net Income for the fiscal year ended December 29, 2018 are net sales of 
approximately $378.2 million, and loss before income taxes of $22.2 million, since the January 17, 2018 acquisition of IXYS. 
The Company recognized approximately $11.9 million of stock compensation expense related to IXYS stock options converted 
to Littelfuse stock options during the fiscal year ended December 29, 2018, of which $4.5 million was recognized immediately 
as it related to prior service periods.

As required by purchase accounting rules, the Company recorded a $36.9 million step-up of inventory to its fair value as of the 
acquisition date based on the preliminary valuation. The step-up was fully amortized as a non-cash charge to cost of goods sold 
during the first and second quarters of 2018, as the acquired inventory was sold, and reflected as other non-segment costs.

During the fiscal year ended December 29, 2018, the Company incurred approximately $11.0 million of legal and professional 
fees related to this acquisition which were primarily recognized as selling, general, and administrative expenses. These costs 
were reflected as other non-segment costs.

2017 Acquisitions

U.S. Sensor

On July 7, 2017, the Company acquired the assets of U.S. Sensor Corporation (“U.S. Sensor”). The acquisition purchase price of 
$24.3 million, net of the finalization of an income tax gross up which was settled in the fourth quarter of 2017, was funded with 
available cash. The acquired business expands the Company’s existing sensor portfolio in several key electronics and industrial 
end markets. U.S. Sensor manufactures a variety of high quality negative temperature coefficient thermistors as well as thermistor 
probes and assemblies. Product lines also include thin film platinum resistance temperature detectors (“RTDs”) and RTD assemblies.

U.S. Sensor acquisition:

Included in U.S. Sensor’s current assets, net was approximately $1.5 million of receivables. All U.S. Sensor goodwill, other assets 
and liabilities were recorded in the Electronics segment and reflected in the U.S. geographic area. The goodwill resulting from 
this acquisition consists largely of the Company’s expected future product sales and synergies from combining U.S. Sensor’s 
products and technology with the Company’s existing electronics product portfolio. Goodwill for the above acquisition is expected 
to be deductible for tax purposes.

As required by purchase accounting rules, the Company recorded a $1.6 million step-up of inventory to its fair value as of the 
acquisition date based on the preliminary valuation. The step-up was amortized as a non-cash charge to cost of goods sold during 
the third quarter of 2017, as the acquired inventory was sold, and reflected as other non-segment costs.

Monolith

In December 2015, the Company invested $3.5 million in the preferred stock of Monolith Semiconductor Inc. (“Monolith”), a 
U.S. start-up Company developing silicon carbide technology, which represented approximately 12% of the common stock of 
Monolith on an as-converted basis. The Company accounted for its investment in Monolith under the cost method with any changes 
in value recorded in other comprehensive income. The value of the Monolith investment was $3.5 million at December 31, 2016.

On February 28, 2017, pursuant to a Securities Purchase Agreement between the Company and the stockholders of Monolith 
(“Securities Purchase Agreement”) and conditioned on Monolith achieving a product development milestone and other provisions, 
the Company acquired 62% of the outstanding common stock of Monolith for $15.0 million. The Securities Purchase Agreement 
includes provisions whereby the Company will acquire the remaining outstanding stock of Monolith (“non-controlling interest”) 
at a time or times based on Monolith meeting certain technical and sales targets. During the first quarter of 2018, Monolith met 
the next set of technical and sales targets. As a result, and pursuant to the Securities Purchase Agreement, in April 2018 the Company 
acquired an additional 19% of the outstanding common stock of Monolith for $5.0 million, of which $4.0 million was paid to the 
stockholders of Monolith. On October 5, 2018, the Company acquired the remaining 19% outstanding common stock for $5.0 
million.

The additional investment, in the first quarter of 2017, resulted in the Company gaining control of Monolith and was accounted 
for  as  a  step-acquisition  with  the  fair  value  of  the  original  investment  immediately  before  the  acquisition  estimated  to  be 
approximately $3.5 million. As the fair value of the investment immediately prior to the transaction equaled the carrying value, 
there was no impact on the Company’s Consolidated Statements of Net Income. As the Securities Purchase Agreement includes 
an obligation of the Company to mandatorily redeem the non-controlling interest for cash, the fair value of the non-controlling 
interest was recognized as a liability on the Company’s Consolidated Balance Sheets. The original investment of $3.5 million, 
additional cash consideration of $14.2 million (net of cash acquired), and the non-cash consideration of the fair value of the 
commitment to purchase the non-controlling interest of $9.0 million resulted in a purchase price of $26.7 million. Changes in the 
fair value of the non-controlling interest are recognized in the Company’s Consolidated Statements of Net Income.

Commencing March 1, 2017, Monolith was reflected as a consolidated subsidiary within the Company’s Consolidated Financial 
Statements. Had the acquisition occurred as of January 1, 2017, the impact on the Company’s consolidated Statements of Net 
Income would not have been material.

(a) The  amortization  adjustment  for  the  twelve  months  ended  December 29,  2018  primarily  reflects  the  reduction  of
amortization expense in the period related to the Order backlog intangible asset. The Order backlog has a useful life of
twelve months and is fully amortized in the fiscal 2017 pro forma results. The amortization adjustment for the twelve
months ended December 30, 2017 reflects incremental amortization resulting for the measurement of intangibles at their
fair values.

(b) The transaction cost adjustments reflect the reversal of certain bank and attorney fees from the twelve months ended

December 29, 2018 and recognition of those fees during the twelve months ended December 30, 2017.

(c) The amortization of inventory step-up adjustment reflects the reversal of the amount recognized during the twelve months
ended December 29, 2018 and the recognition of the full amortization during the twelve months ended December 30,
2017. The inventory step-up was amortized over five months as the inventory was sold.

(d) The stock compensation adjustment reflects the reversal of the portion of stock compensation for IXYS stock options
that were converted to Littelfuse stock options and expensed immediately during the twelve months ended December 29,
2018. The adjustment for the twelve months ended December 30, 2017 reflect the incremental stock compensation for
the converted stock options.

(e) The interest expense adjustment reflects incremental interest expense related to the financing of the transaction.

For the fiscal year ended December 28, 2019, the Company recorded $2.7 million of acquisition-related expenses associated with 
contemplated acquisitions within Selling, general and administrative expenses in the Consolidated Statements of Net Income.

7. Lease Commitments

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company leases office and production space under various non-cancellable operating leases that expire no later than 2025. 
Certain real estate leases include one or more options to renew. The exercise of lease renewal options is at the Company's sole 
discretion. Options to extend the lease are included in the lease term when it is reasonably certain the Company will exercise the 
option. The Company also has production equipment, office equipment and vehicles under operating leases. The depreciable life 
of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option 
that is reasonably certain of exercise. Certain leases include rental payments adjusted periodically for inflation. The lease agreements 
do not contain any material residual value guarantee or material restrictive covenants.

The Company does not have a published credit rating because it has no publicly traded debt; therefore, the Company is generating 
its incremental borrowing rate (IBR), using a synthetic credit rating model that compares its credit quality to other rated companies 
based on certain financial metrics and ratios. The reference rate will be based on the yield curve of companies with similar credit 
quality based on the metrics and adjusted for currency in regions where we have significant operations.

All leases with an initial term of 12 months or less that do not include an option to extend or purchase the underlying asset that 
the Company is reasonably certain to exercise (“short-term leases”) are not recorded on the Consolidated Balance Sheets. Short-
term lease expenses are recognized on a straight-line basis over the lease term.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Revolving Credit Facility / Term Loan

On March 4, 2016, the Company entered into a five-year credit agreement (“Credit Agreement”) with a group of lenders for up 
to $700.0 million. The Credit Agreement consisted of an unsecured revolving credit facility (“Revolving Credit Facility”) of $575.0 
million and an unsecured term loan credit facility (“Term Loan”) of up to $125.0 million. In addition, the Company had the ability, 
from time to time, to increase the size of the Revolving Credit Facility and the Term Loan by up to an additional $150.0 million, 
in  the  aggregate,  in  each  case  in  minimum  increments  of  $25.0  million,  subject  to  certain  conditions  and  the  agreement  of 
participating lenders.

On October 13, 2017, the Company amended the Credit Agreement to increase the Revolving Credit Facility from $575.0 million
to $700.0 million and increase the Term Loan from $125.0 million to $200.0 million and to extend the expiration date from March 
4, 2021 to October 13, 2022. The Credit Agreement also includes the option for the Company to increase the size of the Revolving 
Credit Facility and the Term Loan by up to an additional $300.0 million, in the aggregate, subject to the satisfaction of certain 
conditions set forth in the Credit Agreement. Term Loans may be made in up to two advances. The first advance of $125.0 million
occurred on October 13, 2017 and the second advance of $75.0 million occurred on January 16, 2018. For the Term Loan, the 
Company is required to make quarterly principal payments of 1.25% of the original term loan ($2.5 million quarterly) through 
maturity, with the remaining balance due on October 13, 2022. The Company paid $10.0 million of principal payments on the 
Term Loan for the fiscal year ended December 28, 2019.

Outstanding borrowings under the Credit Agreement bear interest, at the Company’s option, at either LIBOR fixed for interest 
periods of one, two, three or six-month periods plus 1.00% to 2.00%, or at the bank’s Base Rate, as defined, plus 0.00% to 1.00%, 
based upon the Company’s Consolidated Leverage Ratio, as defined. The Company is also required to pay commitment fees on 
unused portions of the credit agreement ranging from 0.15% to 0.25%, based on the Consolidated Leverage Ratio, as defined in 
the agreement. The credit agreement includes representations, covenants and events of default that are customary for financing 
transactions of this nature. The effective interest rate on outstanding borrowings under the credit facility was 3.20% at December 28, 
2019.

As of December 28, 2019, the Company had no amounts outstanding in letters of credit and had available $353.4 million of 
borrowing capacity under the Revolving Credit Facility. At December 28, 2019, the Company was in compliance with all covenants

10. Fair Value of Assets and Liabilities

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

For assets and liabilities measured at fair value on a recurring and nonrecurring basis, a three-level hierarchy of measurements 
based upon observable and unobservable inputs is used to arrive at fair value. Observable inputs are developed based on market 
data obtained from independent sources, while unobservable inputs reflect the Company’s assumptions about valuation based on 
the best information available in the circumstances. Depending on the inputs, the Company classifies each fair value measurement 
as follows:

Level 1—Valuations based on unadjusted quoted prices for identical assets or liabilities in active markets;

Level 2—Valuations based upon quoted prices for similar instruments, prices for identical or similar instruments in 
markets that are not active, or model-derived valuations, all of whose significant inputs are observable, and

Level 3—Valuations based upon one or more significant unobservable inputs.

Following is a description of the valuation methodologies used for instruments measured at fair value and their classification in 
the valuation hierarchy.

Cash Equivalents

Cash equivalents primarily consist of money market funds, which are held with an institution with sound credit rating and are 
highly liquid. The Company classified cash equivalents as Level 1 and are valued at cost, which approximates fair value.

Investments in Equity Securities

Investments in equity securities listed on a national market or exchange are valued at the last sales price and classified within 
Level 1 of the valuation hierarchy. Such securities are further detailed in Note 1, Summary of Significant Accounting Policies and 
Other Information.

The Company has certain convertible debt and convertible preferred stock investments that are accounted for under the cost method 
reflected in Investments and Other assets in the Consolidated Balance Sheets. During the fiscal year ended December 28, 2019, 
the Company recorded impairment charges of $7.3 million in Other Expense (income), net in the Consolidated Statements of Net 
Income to adjust these certain investments to their estimated fair value of $0.4 million. The fair value of these investments are 
measured on a nonrecurring basis and determined to be Level 3 under the fair value hierarchy. The Company's accounting and 
finance management determines the valuation policies and procedures for Level 3 fair value measurements and is responsible for 
the development and determination of unobservable inputs. 

Defined Benefit Plan Assets / Non-qualified Supplemental Retirement and Savings Plan Investments

See Note 11, Benefit Plans, for description of valuation methodologies and investment balances for defined benefit plan assets 
and investments related to the Company’s Non-Qualified Supplemental Retirement and Savings Plan.

There were no changes during 2019 to the Company’s valuation techniques used to measure asset and liability fair values on a 
recurring basis. On October 30, 2019, the Company entered a foreign currency exchange forward contract to mitigate the currency 
fluctuation  risk  between  the  Chinese  renminbi  and  U.S  dollar. The  foreign  currency  contract  was  not  designated  as  a  hedge 
instrument and was marked to market on a monthly basis. The loss of $0.2 million  associated with the change in fair values of 
the foreign currency exchange forward contract was recognized in Other income, net in the Consolidated Statements of Net Income 
along with a $0.2 million liability recorded in Accrued Liabilities on the Consolidated Balance Sheets. The notional value of the 
forward contracts at December 28, 2019 was $16.0 million and expires on May 5, 2020. The Company does not use derivative 
financial instruments for trading or speculative purposes. The fair values of the foreign currency forward contract was determined 
to be Level 2 under the fair value hierarchy and is valued using market exchange rates. As of December 29, 2018, the Company 
held no non-financial assets or liabilities that are required to be measured at fair value on a recurring basis.

In addition to the methods and assumptions used for the financial instruments recorded at fair value as discussed above, the 
following methods and assumptions are used to estimate the fair value of other financial instruments that are not marked to market 
on a recurring basis. The Company’s other financial instruments include cash and cash equivalents, short-term investments, trade 
receivables and its long-term debt. Due to their short-term maturity, the carrying amounts of cash and cash equivalents, short-term 
investments and trade receivables approximate their fair values. The Company’s revolving and term loan debt facilities’ fair values 
approximate book value at December 28, 2019 and December 29, 2018, as the rates on these borrowings are variable in nature.

The Company also sponsors certain post-employment plans in foreign countries and other statutory benefit plans. For the fiscal 
year ended December 28, 2019, December 29, 2018, and December 30, 2017, the Company recorded $1.4 million, $1.8 million, 
$1.1 million expense, respectively, in Cost of Sales and Other expense (income), net within the Consolidated Statements of Net 
Income.  As of December 28, 2019 and December 29, 2018, the Company reported benefit liabilities of $2.8 million and $2.7 
million for these plans, of which $0.9 million and $1.1 million was recorded in Accrued liabilities and $1.9 million and $1.6 
million  was  recorded  in  Other  long-term  liabilities  on  the  Consolidated  Balance  Sheets,  respectively.  For  fiscal  year  ended 
December 28, 2019, the pre-tax amounts recognized in other comprehensive income (loss) as components of net periodic benefit 
costs for these plans were $0.6 million.

Defined Benefit Plan Assets

Based upon analysis of the target asset allocation and historical returns by type of investment, the Company has assumed that the 
expected  long-term  rate  of  return  will  be  4.5%  on  plan  assets. Assets  are  invested  to  maximize  long-term  return  taking  into 
consideration timing of settlement of the retirement liabilities and liquidity needs for benefits payments. Pension plan assets were 
invested as follows, and were not materially different from the target asset allocation:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The  Company  segregated  its  plan  assets  by  the  following  major  categories  and  level  for  determining  their  fair  value  as  of 
December 28, 2019 and December 29, 2018. All plan assets that are valued using the net asset value per share (“NAV”) practical 
expedient have not been included within the fair value hierarchy but are separately disclosed.

Cash and cash equivalents – Carrying value approximates fair value. As such, these assets were classified as Level 1. The Company 
also invests in certain short-term investments which are valued using the amortized cost method and at NAV.

Equity – The values of individual equity securities were based on quoted prices in active markets. As such, these assets are classified 
as Level 1. Additionally, the Company invests in certain equity funds that are valued at calculated NAV.

Fixed income – Fixed income securities are typically priced based on a last trade basis and are exchange-traded. Accordingly, the 
Company classified fixed income securities as Level 1. The Company also invests in certain fixed income funds which are valued 
at NAV.

Insurance Contracts and other – This category includes insurance contracts that are valued by the re-insurer with the valuation 
inputs being not highly observable or traded on an open market.  Accordingly, insurance contracts was categorized as Level 3.  
Additionally, this category includes other assets and liabilities including futures or swaps valued at NAV. 

For any Level 2 and Level 3 plan assets, management reviews significant investments on a periodic basis including investigation 
of unusual fluctuations in price or returns and obtaining an understanding of the pricing methodology to assess the reliability of 
third-party pricing estimates.

The valuation methodologies described above may generate a fair value calculation that may not be indicative of net realizable 
value or future fair values. While the Company believes the valuation methodologies used are appropriate, the use of different 
methodologies or assumptions in calculating fair value could result in different amounts. The Company invests in various assets 
in which valuation is determined by NAV. The Company believes that the NAV is representative of fair value at the reporting date, 
as there are no significant restrictions on redemption of these investments or other reasons to indicate that the investment would 
be redeemed at an amount different than the NAV.

Defined Contribution Plan

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company also maintains a 401(k) savings plan covering substantially all U.S. employees. The Company matches 100% of 
the employee’s annual contributions for the first 4% of the employee’s eligible compensation. The Company may provide an 
additional discretionary match to participants and made discretionary matches of 2% of the employee’s eligible compensation for 
each of the fiscal year ended December 28, 2019, December 29, 2018 and December 30, 2017. Employees are immediately vested 
in  their  contributions  plus  actual  earnings  thereon,  as  well  as  the  Company  contributions.  Company  matching  contributions 
amounted to $5.6 million, $4.5 million, and $3.5 million in 2019, 2018, and 2017, respectively.

Non-qualified Supplemental Retirement and Savings Plan

The Company has a non-qualified Supplemental Retirement and Savings Plan which provides additional retirement benefits for 
certain  management  employees  and  named  executive  officers  by  allowing  participants  to  defer  a  portion  of  their  annual 
compensation. The  Company  maintains  accounts  for  participants  through  which  participants  make  investment  elections. The 
investments are subject to the claims of the Company’s creditors and the Company is responsible for the payment of all benefits 
under the plan from its general assets. As of December 28, 2019, there was $10.5 million of marketable securities related to the 
plan included in Other assets and $10.5 million of accrued compensation benefits included in Other long-term liabilities. The 
marketable securities are classified as Level 1 under the fair value hierarchy as they are maintained in mutual funds with readily 
determinable fair value. The Company made matching contributions to the plan of $0.4 million in 2019.

12. Stock-Based Compensation

Equity Plans: The Company has equity-based compensation plans authorizing the granting of stock options, restricted shares, 
restricted share units, and other stock rights to employees and directors. As of December 28, 2019, there were 1.2 million shares 
available for issuance of future awards under the Company’s equity-based compensation plans.

Stock options generally vest over a three, four or five-year period and are exercisable over either a seven or ten-year period 
commencing from the date of the grant. Restricted shares and share units granted by the Company generally vest over three to 
four years. Stock options and restricted share units may have accelerated vesting upon meeting certain qualified conditions.

Upon completion of the IXYS acquisition, IXYS outstanding options were assumed by  the Company and converted into options 
of 499,027 shares. The Company recognized approximately $11.9 million of stock compensation expense related to IXYS stock 
options converted to Littelfuse stock options during the fiscal year ended December 29, 2018, of which $4.5 million was recognized 
immediately as it related to prior service periods. See Note 2, Acquisitions and Dispositions, for further discussion.

The following table provides a reconciliation of outstanding stock options for the fiscal year ended December 28, 2019.

The total intrinsic value of options exercised during 2019, 2018, and 2017 was $12.5 million, $38.3 million, and $2.2 million, 
respectively. The total fair value of the vested RSU shares was $15.5 million, $20.8 million, and $15.0 million for 2019, 2018, 
and 2017, respectively. The total amount of share-based liabilities paid was $0.9 million, $1.1 million and $0.9 million for 2019, 
2018, and 2017, respectively.

The Company recognizes compensation cost of all share-based awards as an expense on a straight-line basis over the vesting 
period of the awards. At December 28, 2019, the unrecognized compensation cost for options and restricted shares was $17.4 
million before tax, and will be recognized over a weighted average period of 1.8 years. Compensation cost included as a component 
of cost of sales, research and development and selling, general, and administrative expenses for all equity compensation plans 
discussed above was $19.9 million, $28.2 million, and $17.3 million for 2019, 2018, and 2017, respectively. The total related 
income tax benefit recognized in the Consolidated Statements of Net Income was $3.3 million, $6.0 million and $6.0 million for 
2019, 2018, and 2017, respectively.

The Company uses the Black-Scholes option valuation model to determine the fair value of stock option awards granted. The 
weighted average fair value of and related assumptions for options granted are as follows:

Weighted average fair value of options granted
Assumptions:

Risk-free interest rate
Expected dividend yield
Expected stock price volatility

4.4

2017
$30.77

1.79%
0.86%
23.0%

Expected volatilities are based on the historical volatility of the Company’s stock price. The expected life of options is based on 
historical data for options granted by the Company. The risk-free rates are based on yields available at the time of grant on U.S. 
Treasury bonds with maturities consistent with the expected life assumption. Historical nonvested forfeiture information is the 
basis for the forfeiture rate assumptions.

The fair value of RSU is determined based on the Company's stock price on the grant date reduced by the present value of 
expected dividends through the vesting period.

Preferred Stock: The Board of Directors may authorize the issuance of preferred stock from time to time in one or more series 
with such designations, preferences, qualifications, limitations, restrictions, and optional or other special rights as the Board may 
fix by resolution.

Share Repurchase Program

On May 2, 2018, the Company announced that the Company’s Board of Directors had authorized the repurchase of up to 1,000,000
shares of the Company’s common stock under a program for the period May 1, 2018 to April 30, 2019 ("2018 program"). On May 
1, 2019, the Company announced that the Company's Board of Directors had authorized a new program to repurchase up to 
1,000,000 shares of the Company's common stock for the period May 1, 2019 to April 30, 2020 ("2019 program"). During the 
fiscal year 2019, the Company repurchased 579,916 shares of its common stock totaling $95.0 million. During the fiscal year 
2018, the Company repurchased 391,972 shares of its common stock totaling $67.9 million.

14. Income Taxes

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

On December 22, 2017, the U.S. enacted legislation referred to as the "Tax Act". Among other things, the Tax Act reduces the 
U.S. corporate federal income tax rate from 35% to 21%, adds base broadening provisions which limit deductions and address 
excessive international tax planning, imposes a Toll Charge on accumulated earnings of certain non-U.S. subsidiaries and enables 
repatriation of earnings of non-U.S. subsidiaries free of U.S. federal income tax. Other than the Toll Charge (which, except for 
the IXYS impact, was applicable to the Company for 2017), the provisions are generally applicable to the Company in 2018 and 
beyond.

In accordance with the guidance provided in SEC SAB No. 118, in the fourth quarter of 2017 the Company recorded a charge of 
$47.0 million as a provisional reasonable estimate of the impact of the Tax Act, including $49.0 million for the Toll Charge net 
of $2.0 million for other net tax benefits. In the fourth quarter of 2018, within the measurement period outlined in SAB No. 118, 
the Company finalized its estimates of the impact of the Tax Act as of December 30, 2017 and recorded a charge of $3.2 million, 
including $2.3 million for the Toll Charge and $0.9 million for the net impact of other items. In addition, the Company recorded 
$7.0 million for the Toll Charge associated with IXYS as part of the IXYS acquisition purchase price allocation. This was reflected 
in the opening balance sheet as an increase to goodwill and other long-term liabilities.

Although certain administrative guidance has been issued, including final and proposed regulations, the appropriate application 
of many provisions of the Tax Act remain uncertain. The Company used its best judgment as to the application of these provisions 
in determining its final estimates of the impact of the Tax Act as of December 30, 2017, the Toll Charge associated with the IXYS 
acquisition as well as the Company’s income tax expense for the fiscal years ended December 28, 2019 and December 29, 2018. 
Adjustments to income tax expense may be necessary in future periods if provisions of the Tax Act, and their interaction with 
other provisions of the U.S. Internal Revenue Code, are interpreted differently than interpretations made by the Company, whether 
through issuance of additional administrative guidance, or through further review of the Tax Act by the Company and its advisors. 

The Company has elected to pay the 2017 Littelfuse Toll Charge over the eight-year period prescribed by the Tax Act. The long-
term portion of this Toll Charge which remains payable as of December 28, 2019, totaling $23.8 million, is recorded in Other 
long-term liabilities, and the anticipated 2020 annual installment payment of $3.0 million is included in Accrued income taxes, 
on the Consolidated Balance Sheet as of December 28, 2019. The Company did not elect to pay the 2018 IXYS Toll Charge over 
the eight year period provided by the Tax Act and therefore there is no long-term portion of this Toll Charge which remains payable 
as of December 28, 2019. 

One of the base broadening provisions of the Tax Act is commonly referred to as the “GILTI” provisions. In accordance with 
guidance issued by the FASB staff, the Company has adopted an accounting policy to treat any GILTI inclusions as a period cost 
if and when incurred. Thus, for the fiscal years ended December 28, 2019 and December 29, 2018, deferred taxes were computed 
without consideration of the possible future impact of the GILTI provisions, and any current year impact was recorded as a part 
of the current portion of income tax expense.

The current federal tax benefit for 2019 includes a benefit of $3.3 million from the recognition of previously unrecognized tax 
benefits (and the reversal of the related accrued interest) due to a lapse in the statute of limitations. 

The current federal tax benefit for 2018 includes the benefit of current year losses (which served to partially offset the amount of 
the IXYS Toll Charge that would otherwise have been payable).

The current federal and state income tax expense for 2017 includes the preliminary estimate of $49 million for the Toll Charge as 
discussed above, partially offset by 13.0 million of foreign tax credits.

Deferred income taxes are provided for the tax effects of temporary differences between the financial reporting bases and the tax 
bases  of  the  company’s  assets  and  liabilities.  Significant  components  of  the  company’s  deferred  tax  assets  and  liabilities  at 
December 28, 2019 and December 29, 2018, are as follows:

The deferred tax asset valuation allowance is related to certain net operating loss and non-U.S. interest expense carryforwards 
which are not expected to be realized. The remaining net operating loss and non-U.S. interest expense carryforwards either have 
no expiration date or are expected to be utilized prior to expiration (which begin expiring in 2021). No deferred tax asset nor 
valuation allowance has been recorded for certain U.S. and non-U.S. net operating loss carryforwards for which the possibility of 
usage has been determined to be remote.

The Company paid income taxes of $47.6 million, $46.2 million, and $31.8 million in 2019, 2018, and 2017, respectively, and 
received income tax refunds of $7.1 million, $4.3 million, and 13.7 million in 2019, 2018, and 2017, respectively.

Deferred income taxes are not provided on the excess of the investment value for financial reporting over the tax basis of investments 
in those non-U.S. subsidiaries for which such excess is considered to be permanently reinvested in those operations. The Company 
believes the determination of the amount of such deferred income taxes is impractical as it would depend upon income tax laws 
and circumstances at the time of the hypothetical distributions or dispositions. As of December 28, 2019, unremitted earnings of 
the Company’s non-U.S. subsidiaries was approximately $776 million. A distribution of such earnings will generally not be subject 
to U.S. federal income tax. The Company recognized deferred tax liabilities of $13.0 million ($12.6 million for non-U.S. taxes 
net of related U.S. foreign tax credits, and $0.4 million for U.S. state taxes) as of December 28, 2019 and $12.7 million ($12.5 
million for non-U.S. taxes net of related U.S. foreign tax credits, and $0.2 million for U.S. state taxes) as of December 29, 2018, 
related to taxes on certain non-U.S. earnings which are not considered to be permanently reinvested. Some of these non-U.S. taxes 
will provide a U.S. federal income tax benefit as a foreign tax credit, and the amounts as of December 28, 2019 and December 29, 
2018 are net of such benefit (some of which, in respect of the year ended December 29, 2018, was recorded as part of finalizing 
the provisional reasonable estimate of the impact of the Tax Act). 

The Company has three subsidiaries in China which benefit from lowered income tax rates due to “tax holidays” which apply for 
three-year periods, subject to extension. The tax holiday for two of these subsidiaries expired at the end of 2019 (one will seek an 
extension and the tax holiday benefits for the other was not material). The tax holiday for the third subsidiary will expire at the 
end of 2020 and the Company plans to seek an extension. Such tax holidays contributed $4.2 million in tax benefits, or $0.17 per 
diluted share, during 2019. Future year tax benefits will depend upon the Company’s ability to obtain extensions, and the level of 
income earned by the two applicable subsidiaries.

The company recognizes accrued interest and penalties associated with uncertain tax positions as part of income tax expense. The 
company recognized such interest expense of $1.3 million (net of a $0.6 million decrease due to a lapse in the statute of limitations), 
$1.5 million (net of a $0.3 million decrease due to a lapse in the statute of limitations), and $0.9 million in 2019, 2018, and 2017, 
respectively. Accrued interest for such matters included in Other long-term liabilities within the Consolidated Balance Sheets was 
$7.2 million and $5.9 million as of December 28, 2019 and December 29, 2018, respectively.

The amount of unrecognized tax benefits included in Other long-term liabilities within the Consolidated Balance Sheets was $16.7 
million and $18.3 million as of December 28, 2019 and December 29, 2018, respectively. The December 28, 2019 total represents 
the net amount of tax benefits that, if recognized, would favorably affect the effective income tax rate in future periods. Of this 
amount, approximately $0.1 million may be recognized in 2020 based upon the possible lapse in the statute of limitations. None 
of the positions included in unrecognized tax benefits are related to tax positions for which the ultimate deductibility is highly 
certain, but for which there is uncertainty about the timing of such deductibility.

The U.S. federal statute of limitations remains open for the Company for the 2016 tax year and later years, although the Company 
has been audited for the 2016 tax year and the audit concluded in 2018 with no significant adjustments. The U.S. federal statute 
of limitations remains open for IXYS pre-acquisition tax periods ending March 31, 2017 and January 17, 2018. Non-U.S. and 
U.S. state statutes of limitations generally range from three to seven years, although certain jurisdictions do not have a statute 
expiration. Non-U.S. tax examinations occur from time to time, including examinations currently in process in Italy, Canada, and 
Hong Kong. The company does not expect to recognize a significant amount of additional tax expense as a result of concluding 
these examinations.

Potential shares of common stock attributable to stock options excluded from the earnings per share calculation because their 
effect would be anti-dilutive were 129,658, 42,305, and 37,443 shares in 2019, 2018, and 2017, respectively.

On January 17, 2018, the Company acquired IXYS through a combination of cash, Littelfuse common stock, and the value of 
converted, or cash settled IXYS equity awards. The Company issued approximately 2.1 million shares of Littelfuse common 
stock and converted IXYS equity awards into approximately 0.5 million Littelfuse equity awards.

During the fiscal year 2019, the Company repurchased 579,916 shares of its common stock totaling $95.0 million. During the 
fiscal year 2018, the Company repurchased 391,972 shares of its common stock totaling $67.9 million. See Note 12 Stock-Based 
Compensation for further discussion. 

16. Segment Information

The Company and its subsidiaries design, manufacture and sell components and modules for circuit protection, power control and 
sensing  throughout  the  world. The  Company  reports  its  operations  by  the  following  segments:  Electronics, Automotive,  and 
Industrial. An operating segment is defined as a component of an enterprise that engages in business activities from which it may 
earn revenues and incur expenses, and about which separate financial information is regularly evaluated by the Chief Operating 
Decision Maker (“CODM”) in deciding how to allocate resources. The CODM is the Company’s President and Chief Executive 
Officer (“CEO”). The CODM allocates resources to and assesses the performance of each operating segment using information 
about its revenue and operating income (loss) before interest and taxes, but does not evaluate the operating segments using discrete 
balance sheet information.

Sales, marketing, and research and development expenses are charged directly into each operating segment. Purchasing, logistics, 
customer service, finance, information technology, and human resources are shared functions that are allocated back to the three
operating segments. The Company does not report inter-segment revenue because the operating segments do not record it.  Certain 
expenses, determined by the CODM to be strategic in nature and not directly related to segments current results, are not allocated 
but identified as “Other”. Additionally, the Company does not allocate interest and other income, interest expense, or taxes to 
operating  segments.  These  costs  are  not  allocated  to  the  segments,  as  management  excludes  such  costs  when  assessing  the 
performance of the segments. Although the CODM uses operating income (loss) to evaluate the segments, operating costs included 
in one segment may benefit other segments. Except as discussed above, the accounting policies for segment reporting are the same 
as for the Company as a whole.

•

Electronics Segment: Consists of one of the broadest product offerings in the industry, including fuses and fuse accessories,
positive temperature coefficient (“PTC”) resettable fuses, polymer electrostatic discharge (“ESD”) suppressors, varistors,

ITEM 9A. CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed 
in its reports filed under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within 
the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to management, 
including the Company’s Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding 
required disclosure. In designing and evaluating the disclosure controls and procedures, the Company recognizes that any controls 
and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control 
objectives, and the Company is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and 
procedures.

As required by SEC Rule 15d-15(b), the Company carried out an evaluation, under the supervision and with the participation of 
its management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation 
of its disclosure controls and procedures pursuant to SEC Rule 13a-15 as of the end of the period covered by this report. Based 
on the foregoing, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure 
controls and procedures were effective as of December 28, 2019.

Management’s Report on Internal Control over Financial Reporting

Section 404 of the Sarbanes-Oxley Act of 2002 requires management to include in this Annual Report on Form 10-K a report on 
management’s assessment of the effectiveness of the Company’s internal control over financial reporting, as well as an attestation 
report from the Company’s independent registered public accounting firm on the effectiveness of the Company’s internal control 
over financial reporting. Management is responsible for establishing and maintaining adequate internal control over financial 
reporting as such term is defined in Exchange Act Rule 13a-15(f) and 15d-15(f). The Company’s internal control system was 
designed  to  provide  reasonable  assurance  to  its  management  and  the  Board  of  Directors  regarding  the  preparation  and  fair 
presentation of published financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined 
effective  can  provide  only  reasonable  assurance  with  respect  to  financial  statement  preparation  and  presentation. A  material 
weakness is a deficiency, or a combination of deficiencies, in the internal control over financial reporting such that there is a 
reasonable possibility that a material misstatement of the annual or interim financial statement will not be prevented or detected 
on a timely basis.

The  Company’s  management,  including  the  its  Principal  Executive  Officer  and  Principal  Financial  Officer,  assessed  the 
effectiveness  of  the  Company’s  internal  control  over  financial  reporting  as  of  December 28,  2019,  based  upon  the  updated 
framework in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (“COSO”) in 1992 and updated in May 2013. Based on this assessment, the Company’s management concluded that, 
as of December 28, 2019, the Company’s internal control over financial reporting was effective.

Changes in Internal Control over Financial Reporting

There has been no change in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) 
under the Exchange Act) that occurred during the 12 months or fiscal quarter ended December 28, 2019, that has materially affected, 
or is reasonably likely to materially affect, the Company’s internal control over financial reporting.
