For Knowles, 2018 was a year of meaningful progress against our strategy 
to increase exposure to growth markets and diversify our products and 
customers. This enabled Knowles to deliver 11 percent revenue growth 
with strong operating leverage — ahead of the expectations we had in the 
beginning of the year and well above the growth rates we saw in most of 
the end markets we serve. In Audio, our strong yearly results reflect the 
benefits of our transformation from an acoustic component supplier to an 
audio solutions provider. This transformation has allowed us to migrate our 
product portfolio to higher-value solutions and enabled us to increase our 
content per device, and capitalize on the positive macro trends around audio 
and edge processing across Mobile, Ear and IoT applications. In Precision 
Devices, we saw robust demand for our differentiated solutions across 
defense, industrial and automotive end markets. Sales grew across every 
Knowles business unit in 2018, demonstrating the benefits and shareholder 
value created by the business mix and strategy we have in place. 

Mobile

The 2018 Mobile market was characterized by softening demand trends, 
particularly in the second half of the year. That said, we increased sales into 
the mobile market on a year-over-year basis due to improved audio input 
performance and processing being moved to the edge of the network, 
driving more microphones per device, adoption of higher performance 
mics, and implementations of new intelligent audio solutions. Sales to 
Chinese OEMs reached all-time record levels, up over 70 percent from 
2017. This growth was driven by robust demand for higher performance 
microphones and an increase in new intelligent audio design wins. For 
example, we announced that both OPPO and Vivo adopted our smart 
microphones in their flagship handsets, giving these OEMs the ability to 
customize, add new features and differentiate their smartphones in the 
market. This is driving significantly higher audio content per device for 
us through higher ASPs and greater share, while increasing the need for 
additional high-performance MEMS microphones. We grew sales to our 
largest customer in 2018 compared to the prior year, fueled by significant 
increases in microphone sales to non-handset products. I believe continued 
multi mic adoption and additional intelligent audio design wins will help us 
outgrow the mobile market again in 2019. 

Ear

Our growth in the Ear market in 2018 was driven by higher volumes of 
wireless headsets, the increasing number of microphones per headset 
and the implementation of higher performance microphones. Our hearing 
health business also contributed to our year-over-year growth. I continue 
to be very optimistic about the growth prospects in the Ear market given 
our long and successful history of solving challenges in hearing aids, and 
our broad range of solutions, including microphones, balanced armature 
speakers, smart mics and audio processors. Additionally, we are seeing 
that personal voice assistants, such as Amazon’s Alexa and Google’s 
Assistant, are accelerating development for ear-worn devices and placing 
greater importance on voice input. In the future, we expect that AI-enabled 
headsets will be able to automatically improve speech recognition in noisy 
environments and to understand not just our words but the context in 
which we speak them. We see continued convergence in the technology 
requirements between consumer headsets and hearing aid devices for high 
performance audio solutions that are extremely low power, with very small 
footprints. We are uniquely positioned to address the needs of this market 
and see a potential of $10 of content per device, as we focus on enabling 
feature-rich consumer products. 

loT

In the IoT market, we continue to see countless new product launches of 
voice-enabled devices. Amazon and Google voice assistants continue to 
battle to gain voice control of consumers’ connected homes, appliances  
and cars. In China, we are also benefiting from strong growth in Ear and  
IoT demand. All of these devices need microphones and many highlight  
the important trend of processing being moved from the cloud to the edge 
of the network to improve data privacy, security, contextual awareness and 
latency and reduce total cost. Customers recognize that our audio solutions 
are optimized to deliver the best performance for these types of tasks, 
which has resulted in strong design activity across all types of IoT devices 
for our microphones and audio processors. As expected, sales into the Ear 
and IoT markets represented over 20 percent of total microphone sales in 
2018 up from 7 percent in 2016. We made a conscious effort over the past 
several years to diversify microphone revenues, and in 2019 we expect this 
trend to continue with more than 25 percent of our microphone sales to  
be into these markets.

Precision Devices

Our Precision Devices business had an outstanding 2018, with record 
revenues and operating profits. We saw strong demand for our differentiated 
products across multiple end markets. That demand drove higher sales, and 
an acquisition supplemented robust organic growth. We continued to grow 
across defense, medical, telecom, and automotive end markets in 2018, and 
we believe we are positioned for growth in key solutions for electric vehicles 
and 5G infrastructure over the next several years. 

2019 & Beyond

As we enter 2019, all of our businesses are well positioned for continued 
growth. In Audio, the macro trends around better performance and 
edge processing remain favorable and are enabling us to expand our 
total available market and grow our business. We expect to benefit from 
increasing sales in our Ear and IoT markets and growth in Hearing Heath. 
In addition, I expect 2019 to be a strong year for our Intelligent Audio 
business — contributing 2 to 4 percent of total company revenue growth 
on top of sales in our core businesses. Longer term, I believe our family 
of audio processors opens up an incremental $1 billion available market 
for us, while driving increased market share and higher dollar content in 
our core acoustics business. In Precision Devices, we continue to execute 
our playbook and drive strong revenue growth and operating margin 
improvement, both organically and through tuck in acquisitions. I expect 
the growth in both segments will drive total company revenue with  
strong operating leverage in 2019. 

At Knowles, our corporate commitment to acting in an ethical and 
responsible way is central to our mission. Our focus on environmental  
and social responsibility, transparency and engagement guides our 
decision-making processes and keeps us accountable as we continuously 
improve all aspects of our business. We have successfully diversified our 
end market exposure and customer base, developed industry-leading 
solutions and driven top line growth. We look forward to building on  
our momentum to deliver higher-value solutions across our business units  
while improving gross margins and driving enhanced shareholder value.

Sincerely, 

Jeffrey Niew
President and CEO

PART I

Unless the context otherwise requires, references in this Annual Report on Form 10-K to “Knowles,” the “Company,” “we,” “our,” 
or “us” refer to Knowles Corporation and its consolidated subsidiaries. 

Our Company

We are a market leader and global provider of advanced micro-acoustic, audio processing, and precision device solutions, serving 
the mobile consumer electronics, communications, medical, defense,  aerospace, and industrial markets. We use our leading position 
in micro-electro-mechanical systems ("MEMS") microphones and strong capabilities in audio processing technologies to optimize 
audio systems and improve the user experience in mobile, ear, and Internet of Things ("IoT") applications. We are also the leader 
in acoustics components used in hearing aids and have a strong position in high-end capacitors. Our focus on our customers, 
combined with our unique technology, proprietary manufacturing techniques, rigorous testing, and global scale, enables us to 
deliver innovative solutions that optimize the user experience. Knowles, founded in 1946 and headquartered in Itasca, Illinois, has 
approximately 8,000 employees in 11 countries around the world.

Our Strategy

Our primary focus has been to position the Company to benefit from the positive trends we are seeing in our Audio segment. With 
products ranging from mobile phones to headsets, and from smart speakers to household appliances, voice-powered interactions 
are emerging as a critical and necessary feature. Consumers want to engage with technology through natural, spoken commands, 
across the mobile, ear, and IoT markets, and original equipment manufacturers (“OEMs") are racing to develop and deploy the 
technology to enable it. Our unique capabilities in acoustics, digital signal processing, and algorithms place us in a competitive 
position to enable voice and audio input.

We have been focused on strategically positioning the business to support these broader trends around audio input including the 
acquisition of Audience, Inc. ("Audience") in 2015, which brought us essential digital signal processing and algorithm capabilities, 
and the divestiture of our low-margin speaker and receiver product line ("Speaker and Receiver Product Line") in 2016. During 
this  time,  we  have  also  invested  significantly  in  our  core  MEMS  microphone  and  hearing  health  businesses  to  maintain  our 
leadership positions and optimize our manufacturing footprint across our business units. 

In our Precision Devices segment, we continue to drive higher sales growth and improved operating margins through both organic 
initiatives and acquisitions. In 2017, we reshaped our portfolio by divesting our timing device business ("Timing Device Business") 
to increase our focus on growth platforms in Precision Devices where we have strong market positions and attractive margin 
profiles, including industrial, medical, defense, automotive, and telecom applications.

Our Business Segments

In January 2017, the Company changed its internal reporting to drive growth in our core business. Given the changes in the 
allocation of resources and in its internal reporting structure, the Company now reports two segments, Audio and Precision Devices 
("PD"). As a result of this change, transducer products used in hearing health and premium headset applications were moved from 
the  historical  Specialty  Components  segment  into  the  new Audio  segment,  which  includes  the  historical  Mobile  Consumer 
Electronics segment. The capacitor products formerly in the Specialty Components segment are now included in the PD segment.

•  Audio Segment

Our Audio group designs and manufactures innovative audio products, including microphones and balanced armature speakers, 
audio processors, and software and algorithms used in applications that serve the mobile, ear, and IoT markets. Locations include 
the sales, support, and engineering facilities in North America, Europe, and Asia, as well as the manufacturing facilities in Asia.

•  PD Segment

Our PD group specializes in the design and delivery of highly engineered capacitors and radio frequency ("RF") devices for 
technically demanding applications. Our devices are used in applications including power supplies, radar, medical implants, and 
satellites, serving the industrial, defense, aerospace, medical, telecommunications, and automotive markets. Locations include 
the sales, support, engineering, and manufacturing facilities in North America, Europe, and Asia.

4

We sell our products directly to OEMs and to their contract manufacturers and suppliers and to a lesser extent through distributors 
worldwide. Our products by segment on a continuing operations basis are as follows:

•  Audio - Includes analog and digital MEMS microphones, electret condenser microphones, smart microphones, ultrasonic 

sensors, acoustic processors, and balanced armature speakers.

•  PD - Includes capacitors and filters.

Market Trends

In our Audio segment, we have seen an inflection point with voice being embraced as a primary user interface across consumer 
electronic devices. Voice assistants are proliferating throughout a variety of applications from mobile phones to headsets, and from 
smart speakers to household appliances. Consumers want to engage with technology through natural, spoken commands, across 
the mobile, ear, and IoT markets, and OEMs are racing to develop and deploy the technology to enable it. Our core capabilities in 
acoustics, digital signal processing, and algorithms are unparalleled and place us in an ideal position to enable voice and audio 
input.  

Within the hearing aid market, sales are largely driven by aging demographics, healthcare spending, increasing affluence in emerging 
markets, and government subsidies.

Our Precision Devices segment sells multi-layer ceramic capacitors, electromagnetic interference filters, high reliability capacitors, 
single layer capacitors, precision variable capacitors, and thin film devices across diverse end markets, including industrial, defense, 
aerospace, medical, and telecommunications markets. Portions of this segment face much greater exposure to capital investment 
cycles and government spending, both direct and indirect, as some of these end markets are largely dependent on project upgrades, 
expansion, and government contracts.

Geographic Trends

We strive to maintain our manufacturing facilities in close proximity to our direct customers. In the case of Audio, we currently 
operate 5 facilities in Asia to serve the contract manufacturers who build OEM equipment on behalf of our end-customers. These 
contract manufacturers are largely based in China, Taiwan, India, Singapore, Indonesia, and Vietnam. Although end-user demand 
for consumer electronics and hearing aids is global and marketing activities occur globally, the majority of our manufacturing is 
located in Asia, primarily in China, Malaysia, and the Philippines.

In the case of PD, we operate 5 facilities in North America and 1 facility in Asia for the manufacturing of capacitors that support 
our global customers, as well as their suppliers and contract manufacturers.

Competitive Landscape

Success in the electronic components industry is primarily driven by innovation and flexibility as customers compete to gain a 
share of the growing consumer device market. We compete across handset, wearables, and other consumer platforms to deliver 
superior acoustic performance through customized products. Our investments in research and development enable us to capture 
new design wins across consumer OEMs. Our ability to balance and shift between full and semi-automation is key to our ability 
to optimize our operations and operating expenses. Additionally, it is important for suppliers to have flexibility and quick time-
to-market to meet clients’ needs. Notably, according to industry estimates, the product cycle for mobile handsets has shortened 
over recent years. Key competitors include:

•  Audio - AAC Technologies, Goertek, Sonion, and Synaptics; and

•  PD - AVX Corporation, Kemet, and Murata.

In the Audio segment, our investments in research and development enable us to continually introduce new products with higher 
performance. Our customers are adopting these higher value microphones to improve the overall audio performance of their devices 
which in turn improves the end user experience. Typically our new products have higher average selling prices than the products 
they are replacing. Once introduced, the pricing for these products trend lower, as is typical in the consumer electronics market.

5

For products that were introduced more than 18 months ago, we strive to offset anticipated price erosion through bill of material 
cost reductions, yield improvements, equipment efficiency, and movement to lower-cost manufacturing locations.

In the PD segment, the end markets tend to be more stable. We see a highly fragmented set of competitors across capacitor products 
for a diverse set of end markets including industrial, defense, aerospace, medical, and telecommunications.

Customers, Sales, and Distribution

We serve customers in the mobile consumer electronics, industrial, defense, aerospace, medical, and telecommunications markets. 
Our customers include some of the largest OEMs and operators in these markets. In addition, many of our OEM customers outsource 
their manufacturing to Electronic Manufacturing Services (“EMS”) companies. Other customers include global mobile phone 
manufacturers, hearing aid manufacturers, and many of the largest global EMS companies, particularly in China.

We manufacture and develop our products as well as maintain sales and technical customer support offices in North America, 
Europe, and Asia. In our PD segment, we supplement our direct sales force with external sales representatives and distributors. 
Our global distribution center is located in Penang, Malaysia. Our worldwide sales force provides geographically specific support 
to our customers and specialized selling of product lines to various customer bases. For further detail and for additional disclosures 
regarding  sales  and  property,  plant,  and  equipment,  net,  by  geographic  location,  see  Note  17.  Segment  Information  to  our 
Consolidated Financial Statements under Item 8, "Financial Statements and Supplementary Data."

Raw Materials

We use a wide variety of raw materials, primarily metals, and semi-processed or finished components. Commodity pricing for 
various metals, such as palladium, gold, brass, stainless steel, and copper, fluctuates. As a result, our operating results are exposed 
to such fluctuations. Although some cost increases may be recovered through increased prices to customers, if commodity prices 
trend upward, we attempt to control such costs through fixed-price contracts with suppliers and various other programs.

We rely on highly specialized suppliers or foundries for critical materials, components, or subassemblies that are used in our 
products which, in some cases, may be sole sourced from such suppliers or foundries or, such suppliers or foundries may also be 
a strategic supplier to one of our competitors or a customer. The loss of any single supplier has not had a material impact on 
operating profits. However, should an event occur which affects the ability or willingness of any supplier or foundry to continue 
to deliver materials or components to us in a timely manner, we may not be able to identify or qualify an alternative supplier in a 

6

timely manner which, in any such period and future periods, could have a material adverse impact on our results of operations. 
See Item 1A. Risk Factors for additional information regarding risks related to our business.

Research and Development

We concentrate our research and development efforts on the design and development of new products for each of our principal 
markets. We also fund certain other emerging product and technology opportunities. Expenditures for research and development 
in fiscal years 2018, 2017, and 2016 were $100.6 million, $93.4 million, and $92.0 million, respectively. Our future success is 
highly dependent upon our ability to develop complex new products, transfer new products to volume production, introduce them 
into the marketplace in a timely fashion, and have them selected for design into our customers’ products at competitive prices. 
Our future success may also depend on increasing acoustic content in our customers’ products including assisting our customers 
with integration of our products and software into their new products and providing support from the concept stage through design, 
launch, and production ramp.

Intellectual Property and Intangible Assets

We rely on patent, copyright, trademark, and trade secret laws to protect our intellectual property, products, and technology. Our 
U.S. patents expire in calendar years 2019 through 2037. While our patents are an important element of our success, our business 
as a whole is not dependent on any one patent or group of patents. We do not anticipate any material effect on our business due to 
any patents expiring in 2019, and we continue to obtain new patents through our ongoing research and development. We have 
maintained U.S. federal trademark registrations for KNOWLES, Knowles logo designs, along with various other trademarks. 
These U.S. registrations may be renewed as long as the marks continue to be used in interstate commerce. We have also filed or 
obtained  foreign  registration  for  these  marks  in  other  countries  or  jurisdictions  where  we  conduct,  or  anticipate  conducting, 
international business. To complement our own research and development efforts, we have also licensed and expect to continue 
to license, a variety of intellectual property and technologies important to our business from third parties. See Item 1A. Risk Factors 
for additional information regarding risks related to our business.

Seasonality

In general, our businesses tend to have higher revenues in the third and fourth quarters of each fiscal year. This is particularly true 
of those businesses that serve the consumer electronics market. Our businesses tend to have short product cycles due to the highly 
technical nature of the industries they serve which can result in new OEM product launches that can impact quarterly revenues, 
earnings, and cash flow.

Environmental and Social Responsibility Matters

As a socially responsible company, we strive to align our business practices and policies with the needs of our key stakeholders, 
and  to  that  end  we  have  developed  environmental,  social,  and  governance  policies  which  can  be  accessed  at  our  website, 
www.knowles.com.

Our operations are governed by a variety of international, national, state, and local environmental laws. These regulations include 
limitations  on  discharge  of  pollutants  to  the  air,  water,  and  soil;  manufacturing  chemical  use  and  handling  restrictions;  and 
requirements with respect to the treatment, transport, storage, and disposal of solid and hazardous wastes. We are committed to 
continued compliance and believe our operations generally are in substantial compliance with these laws.

We are dedicated to the preservation and improvement of our global environment. We have established a Green Materials Policy, 
pursuant to which we have established a Green Materials Standard. Our products are in compliance with the European Union 
Restriction of Hazardous Substances ("EU RoHS") and Waste Electrical and Electronic Equipment ("WEEE") directives. This 
standard is based on the list of substances identified in the Joint Industry Guide-101 Standard which is endorsed by the Electronic 
Industry Association, the Joint Electronics Device Engineering Council, and the Japan Green Procurement Survey Standardization 
Initiative associations as well as the Sony Standard-00259. As part of Knowles’s commitment to social responsibility and compliance 
with Rule 13p-1 under the Securities Exchange Act of 1934, as amended, (the "Exchange Act") it is our goal to only use 3TG 
minerals in our products that do not directly or indirectly finance or benefit armed groups in the Democratic Republic of the Congo 
region.

7

Employees

We currently employ approximately 8,000 persons across our facilities in 11 countries. Approximately 78% of our employees are 
located in Asia. We are subject to various local, national, and multi-national laws and regulations relating to our relationships with 
our  employees.  Our  workforce  in  the  United  States  is  not  unionized. We  believe  we  generally  have  good  relationships  with 
employees and their representative organizations.

ITEM 1A. RISK FACTORS

Cautionary Statement Concerning Forward-Looking Statements

This Annual Report on Form 10-K contains certain statements regarding business strategies, market potential, future financial 
performance, future action, results, and any other statements that do not directly relate to any historical or current fact which are 
“forward-looking” statements within the meaning of the Securities Act of 1933, as amended (the "Securities Act"), the Exchange 
Act, and the Private Securities Litigation Reform Act of 1995. The words “believe,” “expect,” “anticipate,” “project,” “estimate,” 
“budget,”  “continue,”  “could,”  “intend,”  “may,”  “plan,”  “potential,”  “predict,”  “seek,”  “should,”  “will,”  “would,”  “expect,” 
“objective,” “forecast,” “goal,” “guidance,” “outlook,” “effort,” “target,” and similar expressions, among others, generally identify 
forward-looking statements, which speak only as of the date the statements were made.

In particular, information included under the sections entitled “Business,” “Risk Factors,” and “Management’s Discussion and 
Analysis of Financial Condition and Results of Operations” contain forward-looking statements.

Readers are cautioned that the matters discussed in these forward-looking statements are subject to risks, uncertainties, assumptions, 
and other factors that are difficult to predict and which could cause actual results to differ materially from those projected, anticipated, 
or implied in the forward-looking statements. Where, in any forward-looking statement, an expectation or belief as to future results 
or events is expressed, such expectation or belief is based on the current plans and expectations of management and expressed in 
good faith and believed to have a reasonable basis, but there can be no assurance that the expectation or belief will be achieved 
or accomplished. Many factors that could cause actual results or events to differ materially from those anticipated include those 
matters described under the sections entitled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition 
and Results of Operations.” We caution you not to place undue reliance on these forward-looking statements, which speak only 
as of the date of this Annual Report on Form 10-K and Knowles does not assume any obligation to update any forward-looking 
statement as a result of new information, future events, or otherwise, except as required by applicable law. All forward-looking 
statements, expressed or implied, included in this Annual Report on Form 10-K are expressly qualified in their entirety by this 
cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral 
forward-looking statements that we may make or persons acting on our behalf may issue.

You should consider each of the following factors as well as the other information in this Annual Report on Form 10-K, including 
our financial statements and the related notes, in evaluating our business and our prospects. The risks and uncertainties described 
below are not the only ones we face. In general, we are subject to the same general risks and uncertainties that impact many other 
companies such as general economic, industry, and/or market conditions and growth rates; possible future terrorist threats or armed 
conflicts and their effect on the worldwide economy; and changes in laws or accounting rules. Additional risks and uncertainties 
not presently known to us or that we currently consider immaterial may also impair our business operations. If any of these risks 
occur, our business and financial results could be harmed. In that case, the trading price of our common stock could decline.

Risks Related To Our Business

We depend on the mobile handset market for a significant portion of our revenues, and any downturn or slower than expected 
growth in this market could significantly reduce our revenues and adversely impact our operating results.

Our Audio segment accounted for 83% of our consolidated revenues for the year ended December 31, 2018, and the mobile handset 
market accounted for approximately 35% of our consolidated revenues. While other markets such as mobile headsets, wearables, 
and IoT are gaining in significance, we expect that a substantial portion of our consolidated revenues will continue to be attributable 
to  the  mobile  handset  market,  which  is  cyclical  and  characterized  by  continuous  and  rapid  technological  change,  product 
obsolescence, price erosion, evolving standards, short product life cycles, and significant fluctuations in product supply and demand. 
Moreover, the mobile handset market may not continue to grow at the rate experienced in recent years or may decline for reasons 
outside of our control including competition among market participants, market saturation, and global economic conditions. The 
mobile handset market has experienced and may experience periodic downturns which may be characterized by diminished product 
demand, production overcapacity, high inventory levels, and accelerated erosion of average selling prices. Given that the strength 
of the mobile handset market is a primary driver of revenues for our Audio segment, any downturn in the mobile handset market 
could have a material adverse effect on our business and operating results. In addition, a decline in global economic conditions, 
particularly in China and other geographic regions with high concentrations of mobile handset users, could have adverse, wide-
ranging effects on demand for our products or technologies, the products and services of our customers or licensees, particularly 
OEM handset manufacturers, the solvency of key suppliers, failures by counterparties, and negative effects on mobile handset 
inventories. In addition, our customers’ ability to purchase or pay for our products and services and their customers’ ability to 
upgrade their mobile handsets could be adversely affected by economic conditions, leading to a reduction, cancellation, or delay 
of orders for our products or services.

We derive the majority of our Audio revenues from MEMS microphones sold to the mobile handset market and a significant 
reduction in our sales of MEMS microphones could significantly reduce our revenues and adversely impact our operating 
results.

Within  our Audio  segment,  revenues  are  generated  primarily  from  the  sales  of  our  MEMS  microphones.  Sales  of  MEMS 
microphones accounted for approximately 60% of our total revenues for fiscal 2018. We expect that a substantial portion of our 
revenues will continue to be attributable to sales of MEMS microphones and any weakening of demand, loss of market share, or 
other factors adversely affecting our levels and the timing of our sales of MEMS microphones, including our customers’ product 
release cycles, market acceptance, product competition, the performance and reliability of our MEMS microphones, and economic 
and market conditions could cause our Audio revenues to substantially decline, which may have a material adverse effect on our 
operating results.

Our largest segment, Audio, derives a significant portion of its revenues from a limited number of OEM customers. If revenues 
derived from these customers decrease or the timing of such revenues fluctuates, our operating results could be adversely 
affected.

Our Audio segment derives a significant portion of revenues from a small number of OEM customers. For 2018, Audio top five 
customers accounted for approximately 45% of Audio’s revenues. For the year ended December 31, 2018, Apple Inc. accounted 
for approximately 23% of Audio’s revenues and 19% of total company revenues. The mobile handset industry is also subject to 
intense competition that could result in decreased demand and/or declining average selling prices for our products and those of 
our OEM customers. The loss of any one of Audio’s top customers or a reduction in the purchases of Audio’s products by such 
customers would reduce our total revenues and may have a material adverse effect on our operating results, and any delay of a 
significant volume of purchases by any one of our top customers, even if only temporary, would reduce our revenues in the period 
of the delay and may have a material adverse effect on our operating results. Further, concentration of market share among a few 
companies and the corresponding increase in purchasing power of these companies may result in lower prices for our products 
which, if not offset by a sufficient increase in the volume, or favorable changes in the mix, of purchases of our products, could 
have a material adverse effect on our revenues and margins. In addition, the timing, volume, and mix of purchases by our significant 
customers may be impacted by the timing of such customers’ new or next generation product introductions, and the timing of such 
introductions may have a material adverse effect on our operating results. Accordingly, if current market and industry dynamics 
continue, our Audio segment’s revenues will continue to depend largely upon, and be impacted by the timing, volume, and mix 
of future purchases by a limited number of our OEM customers.

If we are unable to continue to offset erosion of average selling prices in our Audio segment our gross margins may be adversely 
affected.

Like most technology sectors, the mobile handset industry has traditionally experienced an erosion of average selling prices due 
to a number of factors, including intense competition, component pricing trends, changes in demand mix, excess inventories, and 
rapid obsolescence resulting from technology advances. Within our Audio segment, while average selling prices vary significantly 
on a product to product basis, we have generally been successful with largely offsetting price erosion by shifting our product mix 
to new, higher end or higher performance microphones and gradually shifting customers from analog microphones to higher value 
digital microphones. To offset average selling price erosion, we must either continue to be successful with these initiatives or 
increase our selling prices. If we are unable to continue to offset average selling price erosion, the average selling prices of our 
products may decrease and our future operating results may be materially adversely affected.

We rely on highly specialized suppliers for a variety of highly engineered or specialized components, and other inputs which 
we may not be able to readily identify alternatives or substitutes in the event of a supply disruption or capacity constraint at or 
by any of these suppliers, which could have a material adverse impact on our results of operations. 

Certain of our businesses rely on highly specialized suppliers or foundries for critical materials, components, or subassemblies 
that are used in our products. In some cases, such suppliers or foundries may be our sole source of supply or, such suppliers or 
foundries may also be a strategic supplier to one of our competitors or a customer. In either of these cases, should an event occur 
which affects the ability or willingness of any of such supplier or foundry to continue to deliver materials or components to us in 
a timely manner, we may not be able to identify or qualify an alternative supplier in a timely manner which, in any such period 
and future periods, could have a material adverse effect on our results of operations. Potential events or occurrences which could 
cause business or supply disruptions or affect the ability or willingness of a supplier or foundry to continue to supply us include 
changes in market strategy, the acquisition of, sale, or other change in control or ownership structure of a supplier or foundry, 
strategic divestiture, bankruptcy, insolvency or other financial difficulties, business disruptions, operational issues, or capacity 
constraints at a supplier or foundry.

Global markets for our products are highly competitive and subject to rapid technological change. If we are unable to develop 
new  products  and  compete  effectively  in  these  markets,  our  financial  condition  and  operating  results  could  be  materially 
adversely affected.

We compete in highly competitive, technology-based, industries that are highly dynamic as new technologies are developed and 
introduced. Our competitors may introduce products that are as or more technologically advanced than our products or launch 
new products faster than we can, which may result in a loss of market share or revenue by us. If we are unable to anticipate or 
match our competitors’ development or launch of new products, identify customer needs and preferences on a timely basis, or 
successfully launch or ramp production of our new products, our business and operating results may be materially adversely 
affected.

We operate in the highly competitive mobile handset industry, which requires us to invest significant capital in developing, 
qualifying, and ramping production of new products without any assurance of product sales which could negatively impact 
our operating results and profits.

A significant portion of our consolidated revenues are derived from acoustic components and audio solutions, including software, 
that are required to go through extensive customer qualification processes before being selected by customers for inclusion in their 
end products. In order to meet the product launch schedules of our top customers, we may invest capital and devote substantial 
resources, including design, engineering, sales, marketing, and programming efforts, based on non-binding forecasts provided by 
these customers, without any assurance that our products will be designed into a customer’s product or qualified by the customer. 
In such cases, if our product is not designed into or qualified by the customer, we may not recover or realize any return on the 
capital that we invested and our operating results may be materially adversely affected.

In addition, the time required and costs incurred by us to ramp-up production for new products can be significant. Certain non-
recurring costs and expenditures for tooling and other equipment may not be reusable in manufacturing products for other customers 
or different products for the same customer. Product ramps typically involve greater volumes of scrap and risks to execution such 
as higher costs due to inefficiencies and delays in production, all of which can have a material adverse effect on our operating 
results.

10

Our foreign operations, supply chain, and footprint optimization strategies are each subject to various risks that could materially 
adversely impact our results of operations and financial position.

Many of our manufacturing operations, research and development operations, vendors, and suppliers are located outside the United 
States and if we are unable to successfully manage the risks associated with our global operations, our results of operations and 
financial position could be negatively impacted. These risks include:

o  

o  

o  

o  

o  

labor unrest and strikes, particularly in Asia, where the majority of our manufacturing operations are located;

earthquakes, floods, and other natural disasters or catastrophic events, particularly in Asia, where the majority of our 
manufacturing operations are located;

acts of terrorism or armed conflicts;

government embargoes, trade restrictions, and import and export controls; and

transportation delays and interruptions.

Given that many of our manufacturing operations are located outside the United States, a border tax, if enacted, could have a 
material adverse effect on our operating results.

Global economic conditions and changes in U.S. and International Trade Policy could materially adversely impact our business, 
results of operations, and financial position.

The global economic instability of the past few years has caused, among other things, declining consumer and business spending, 
volatile raw material prices, instability in credit markets, high unemployment, fluctuating interest and exchange rates, and other 
challenges. The Company's business and operating results have been adversely affected by these global economic conditions and 
remain vulnerable to future adverse impacts. In particular, our sales to customers in China continue to be impacted by the recent 
economic slowdown in China. Any continued or prolonged economic deceleration in China may have a material adverse effect 
on our sales to customers in China, our operating results, and our financial condition. 

Further, rising international trade tensions, new or increased tariffs and trade wars among countries have and may continue to 
impact the global economy and the trade policies of the United States. The Trump Administration has indicated and demonstrated 
its intent to alter the United States’ government’s approach to international trade policy using many tactics at its disposal including 
the  renegotiation,  termination  or  threatened  termination,  or  renegotiation  of  certain  existing  bilateral  or  multi-lateral  trade 
agreements and treaties with, the imposition of tariffs on a wide range of products and other goods manufactured in, China, countries 
in Europe, and other countries and the imposition of sanctions on countries and companies that it has concluded are directly or 
indirectly dodging United States’ trade sanctions. Given that the majority of our largest manufacturing facilities are located in 
China and Southeast Asia, trade policy changes in the United States, China or other countries, such as the tariffs and sanctions 
currently proposed, implemented, and threatened by the Trump Administration, present particular risks for us that could adversely 
impact our results of operations and financial condition. New or increased tariffs implemented in China are having an adverse 
effect on a small percentage of our capacitor products, tariffs announced but not yet implemented could have an adverse effect on 
our other products, and threatened tariffs could adversely affect all of our products. We cannot predict future foreign trade policy 
in the United States or other countries, the terms of any new or renegotiated trade agreements or treaties, or tariffs or the impact 
of such matters on our business. A trade war involving the United States is likely to negatively impact world trade and the world 
economy in various ways and, consequently, have a material adverse effect on our results of operations and financial condition. 
To the extent that tariffs, trade restrictions, or sanctions imposed by the United States or other countries increase the price of, affect 
customer demand for, affect our ability to supply our products, or create adverse tax consequences, in the United States or other 
countries, our business and our operating results may be adversely affected. As a result, changes in international trade policy, 
changes in trade agreements, the imposition of tariffs or sanctions by the United States or other countries could materially adversely 
affect our results of operations and our financial condition.

Our success depends on our ability to attract and retain key employees, and if we are unable to attract and retain such qualified 
employees, our business and our ability to execute our business strategies may be materially impaired.

Our future success depends largely on the continued service and efforts of our executive officers and other key management and 
technical personnel and on our ability to continue to identify, attract, retain, and motivate them, particularly in an environment of 
cost reductions and a general move toward more performance-based compensation for executives and key management.

11

  
Implementing our business strategy also requires specialized engineering and other talent, as our revenues are highly dependent 
on technological and product innovations. Competition for such experienced technical personnel in our industry and where we 
are located is intense, and we cannot assure  that we can continue to recruit and retain such  personnel. For  example, there is 
substantial competition in China for experienced engineers and technical personnel where most of our operations are located and 
for machine learning and software engineers in California and India where we primarily conduct research and development for 
our software and intelligent audio products, which may make it difficult for us to recruit and retain  key employees. If we are 
unable to attract and retain such qualified employees, our business and our ability to execute our business strategies may be 
materially impaired.

Our revenues, operating profits, and cash flows could be materially adversely affected if we are unable to protect or obtain 
patent and other intellectual property rights or if intellectual property litigation is successful against us.

We employ various measures to maintain, protect, and defend our intellectual property, including enforcing our intellectual property 
rights in various jurisdictions and forums throughout the world. However, policing unauthorized use of our products, technologies, 
and proprietary information is difficult and time consuming and these measures may not prevent our intellectual property from 
being challenged, invalidated, copied, disclosed, or circumvented. We also may not be successful in litigation or other actions to 
enforce our intellectual property rights, particularly in countries where intellectual property rights are not highly developed or 
protected. Litigation, if necessary, may result in retaliatory legal proceedings alleging infringement by us of intellectual property 
owned  by  others. We  have  had  and  may  in  the  future  have  difficulty  in  certain  circumstances  in  protecting  or  enforcing  our 
intellectual property rights, including collecting royalties for use of certain patents included in our patent portfolio in certain foreign 
jurisdictions  due  to,  among  other  things:  policies  of  foreign  governments;  challenges  to  our  licensing  practices  under  such 
jurisdictions’ competition laws; failure of foreign courts to recognize and enforce judgments of contract breach and damages issued 
by courts in the United States; and/or challenges pending before foreign patent authorities as to the validity of our patents and 
those owned by competitors and other parties.

The expense of protecting, defending, and enforcing our intellectual property, or defending claims that our products, technology, 
or manufacturing processes infringe the intellectual property rights of others, can vary significantly period to period and, in any 
given period, could have a material adverse effect on our operating results. In addition, in any period, we may have liability for 
damages arising out of adverse judgments for intellectual property claims that may have a material adverse effect on our operating 
results and financial condition.

We have invested and continue to make strategic investments and acquisitions that, if not successful, could have a material 
adverse effect on our financial results.

We engage in strategic transactions and make strategic investments including investments in emerging technology companies and 
intellectual property which are focused on growth by positioning the Company for expansion into new markets, territories or 
technologies, exploiting new or growing customer or market opportunities and developing new technologies and products. Such 
acquisitions and strategic investments naturally entail significant risks and uncertainties, some of which are beyond our control.  
We may not, for example, be able to retain key employees, customers, or suppliers of acquired companies, derive value from 
acquired  technology  or  assets  and  we  may  experience  delays  in  achieving  cost  synergies  or  higher  than  expected  costs  in 
implementing them. In addition, due to our inexperience with certain adjacent or complimentary technologies and doing business 
in certain geographic regions that may be served by acquired businesses, we may underestimate the costs or overestimate the 
benefits that we expect to realize from such acquisitions or investments, and we may not achieve them. We cannot, therefore, 
provide assurance that each of our acquisitions or strategic investments will be accretive or generate anticipated financial returns. 
If, for any of these or for unforeseen reasons, our strategic acquisitions or investments fail to meet our expectations or forecasts, 
our business and results of operations may be materially adversely affected.

12

Our stock price has been and may continue to be volatile and may fluctuate significantly which may adversely impact investor 
confidence and increase the likelihood of securities class action litigation.

Our common stock price has experienced substantial volatility in the past and may remain volatile in the future. Volatility in our 
stock price can be driven by many factors including divergence between our actual or anticipated financial results and published 
expectations  of  analysts  or  the  expectations  of  the  market,  market  conditions  in  our  industry,  announcements  that  we,  our 
competitors, our vendors, or our customers may make regarding their operating results, technological innovations, and the gain 
or loss of customers, or key opportunities. During 2018, our closing stock price ranged from a high of $18.13 per share to a low 
of $11.00 per share. Our common stock is also included in certain market indices, and any change in the composition of these 
indices to exclude our company may adversely affect our stock price. Increased volatility in the financial markets and/or overall 
economic conditions may reduce the amounts that we realize in the future on our cash equivalents and/or marketable securities 
and may reduce our earnings as a result of any impairment charges that we record to reduce recorded values of marketable securities 
to their fair values.

Further, securities class action litigation is often brought against a public company following periods of volatility in the market 
price of its securities. Due to changes in our stock price, we may be the target of securities litigation in the future. Securities 
litigation could result in substantial uninsured costs and divert management’s attention and our resources.

Our effective tax rate may fluctuate which will impact our future financial results.

Our effective tax rate may be adversely impacted by, among other things, changes in the mix of our earnings among countries 
having differing statutory tax rates, changes in the valuation of deferred tax assets, or changes in tax laws where we operate, 
including the resulting tax effects of the Tax Cuts and Jobs Act (“Tax Reform Act”). We cannot give any assurance as to the stability 
or predictability of our effective tax rate in the future because of, among other things, uncertainty regarding the tax laws and 
policies of the countries where we operate.

The  estimated  effects  of  applicable  tax  laws,  including  current  interpretation  of  the  Tax  Reform Act  and  recently  proposed 
regulations on the Section 965 deemed repatriation tax on U.S. persons with foreign earnings accumulated offshore, have been 
incorporated into our financial results. The U.S. Treasury Department, Internal Revenue Service, and other standard-setting bodies 
could interpret or issue future legislation or guidance which impact how provisions of the Tax Reform Act will be applied or 
otherwise administered that is different from our interpretation, which could have a material adverse impact on our effective tax 
rate as well as our future financial results and tax payments.

Further, our tax returns are subject to periodic reviews or audits by domestic and international authorities, and these audits may 
result in adjustments to our provision for taxes or allocations of income or deductions that result in tax assessments different from 
amounts that we have estimated. We regularly assess the likelihood of an adverse outcome resulting from these audits to determine 
the adequacy of our provision for taxes. There can be no assurance as to the outcome of these audits or that our tax provisions will 
not change materially or be adequate to satisfy any associated tax liability. If our effective tax rates were to increase or if our tax 
liabilities exceed our estimates and provisions for such taxes, our financial results could be adversely affected.

Our effective tax rate is favorably impacted by tax holidays granted to us by certain foreign jurisdictions, which lowers the tax 
rates we are subject to for a period of time as compared to the countries' statutory tax rates. These tax holidays are subject to the 
satisfaction of certain conditions, including exceeding certain annual thresholds of operating expenses and gross sales. If we fail 
to satisfy such conditions, our effective tax rate may be materially adversely impacted. For additional detail, see Note 12. Income 
Taxes to our Consolidated Financial Statements under Item 8, "Financial Statements and Supplementary Data." Moreover, tax 
rates and laws in the countries where we operate may change, or tax reforms may be enacted domestically or in foreign jurisdictions 
which adversely affect our liquidity, cash flows, and future reported financial results or our ability to continue to structure and 
conduct our business as is done currently.

We are subject to potentially material liability for breaches of confidentiality agreements with certain of our top customers.

We have entered into non-disclosure agreements with several of our top customers which require us not to disclose and to protect 
certain information regarding, among other things, aspects of those customers’ businesses plans, products, and technology. These 
confidentiality agreements, in some cases, impose strict liability on us in the event of any breach of these agreements by us or our 
employees or agents and, should such a breach occur, any resulting damage award or settlement could have a material adverse 
effect on our operating results and financial condition.

13

Our business and operations could suffer in the event of security breaches or other unauthorized disclosures.

We have taken and continue to actively take measures to protect the various proprietary information, algorithms, source code, and 
confidential data relating to both our and our customers’ business and products that is stored on our computer networks, servers, 
and peripheral devices, as well as on servers owned or managed by third party vendors whom we leverage. Such data and information 
remains vulnerable to cyber attacks, cyber breaches, theft, or other unauthorized disclosure which, if successful, could result in 
loss of valuable intellectual property, disclosure of confidential customer or commercial data, disclosure of government classified 
information, or system disruptions and subject us to civil liability and fines or penalties, damage our brand and reputation or 
otherwise harm our business, any of which could be material. Should any security breach result in the disclosure of certain of our 
customers’ or business partners’ confidential information, we may incur liability to such customers or business partners under 
confidentiality agreements that we are party to with such parties. In addition, delayed sales, lower margins, or lost customers 
resulting from security breaches or network disruptions could materially reduce our revenues, materially increase our expenses, 
damage our reputation, and have a material adverse effect on our stock price.

There is also a danger of industrial espionage, unauthorized disclosures, theft of information or assets (including source code), or 
damage to assets by people who have gained unauthorized access to the Company's facilities, systems, or information. Such 
breaches, misuse, or other disruptions could lead to unauthorized disclosure of confidential or proprietary information or improper 
usage or sale of the Company's products or intellectual property without compensation and theft, manipulation, and destruction 
of private and proprietary data, which could result in defective products, production downtimes, lost revenue, or damage to our 
reputation, and have a material adverse effect on our stock price.

Our net exposure to exchange rate fluctuations could have a material adverse effect on our results of operations.

We  conduct  a  significant  amount  of  business  outside  the  United  States  and  adverse  movements  in  currency  exchange  rates, 
particularly the Malaysian ringgit, the Chinese renminbi (yuan), and the Philippine peso, may, in any period or periods, could have 
a material adverse effect on our business and our operating results due to a number of factors, including, among others:

o

o

o

o

o

o

our products are manufactured and sold outside the United States which increases our net exposure to changes in foreign 
exchange rates;

our products, which are typically sold in U.S. dollars, may become less price-competitive outside the United States as 
a result of unfavorable foreign exchange rates;

certain of our revenues that are derived from customer sales denominated in foreign currencies could decrease;

our foreign suppliers may raise their prices if they are impacted by currency fluctuations, resulting in higher than expected 
costs and lower margins; 

the cost of materials, products, services, and other expenses outside the United States could be materially impacted by 
a weakening of the U.S. dollar; and

a sustained weakening of the U.S. dollar for an extended period could have a material adverse impact on our operating 
results and financial position.

14

Our products are complex and could contain defects, which could result in material costs to us and harm our business.

Our products are complex and could contain defects, which could result in material costs to us. Product development in the markets 
we serve is becoming more focused on audio signal processing for improved audio performance and to enable intelligent and more 
sophisticated audio solutions. The increasing complexity of our products increases the risk that we or our customers or end users 
could discover latent defects or subtle faults after significant volumes of product have been shipped. This could result in material 
costs and other adverse consequences to us including, but not limited to: loss of customers, reduced margins, damage to our 
reputation, a material product recall, replacement costs for product warranty and support, payments to our customers related to 
recall claims as a result of various industry or business practices, a delay in recognition or loss of revenues, loss of market share, 
or failure to achieve market acceptance, and a diversion of the attention of our engineering personnel from our product development 
efforts. In addition, any defects or other problems with our products could result in financial losses or other damages to our 
customers who could seek damages from us for their losses. A product liability or warranty claim brought against us, even if 
unsuccessful, would likely be time consuming and costly to defend. In particular, the sale of systems and components that are 
incorporated into mobile handsets for the global mobile phone industry involves a high degree of risk that such claims may be 
made. Due to the complex nature of our products, quality and reliability issues may be identified after significant volumes of a 
product have been shipped to a large customer. While we have attempted to contractually limit our financial exposure with many 
of our customers for such claims, a warranty or product liability claim against us in excess of our available insurance coverage 
and established reserves, or a determination that we have liability or an obligation to cover the costs of a customer product recall, 
could have a material adverse effect on our business, results of operations, and financial condition.

In addition, our products are typically sold to customers at prices that are significantly lower than the cost of the customer’s products 
in which they are incorporated. Given that a defect in one of our products could give rise to failures in the products that incorporate 
them, we may face claims for damages that are disproportionate to the revenues we receive from the products involved and because 
we are self-insured for matters relating to product quality a significant claim(s) could have a material adverse effect on our financial 
position. Moreover, to the extent a defect in one of our products is caused by a defective component supplied to us by a third party, 
we may, nonetheless, be liable to the customer and be unsuccessful in seeking indemnification from that third party.

Our goodwill, other intangible assets, or long-lived assets may become impaired, which could result in a significant charge to 
earnings.

We hold significant amounts of goodwill, other intangible assets, and long-lived assets, and the balances of these assets could 
increase in the future if we acquire other businesses. At December 31, 2018, the balance of our goodwill, other intangible assets, 
and long-lived assets was $1.2 billion and the total market value of the Company’s outstanding shares was $1.2 billion. Under 
generally accepted accounting principles in the United States ("U.S. GAAP"), we review our goodwill, other intangible assets, 
and long-lived assets for impairment when events or changes in circumstances indicate the carrying value of such goodwill, other 
intangible assets, or long-lived assets may not be recoverable. In addition, we test goodwill and other indefinite-lived intangible 
assets for impairment annually. Factors that may be considered a change in circumstances, indicating that the carrying value of 
our goodwill, other intangible assets, or long-lived assets may not be recoverable, include, but are not limited to, a sustained decline 
in stock price and market capitalization, significant negative variances between actual and expected financial results, reduced 
future cash flow estimates, adverse changes in legal factors, failure to realize anticipated synergies from acquisitions, and slower 
growth rates in our industry. We may be required to record a significant charge to earnings in our financial statements during the 
period in which any impairment of our goodwill, other intangible assets, or long-lived assets is determined to exist, negatively 
impacting our results of operations. If our market capitalization was to fall below the book value of our total stockholders’ equity 
for a sustained period, we may conclude that the fair value of certain of our intangible or long-lived assets is materially impaired. 
In this case, we would be required under U.S. GAAP to record a non-cash charge to our earnings which could have a material 
adverse effect on our business, results of operations, and financial condition.

Our credit agreement requires us to comply with certain financial covenants and our failure to comply could have a material 
adverse effect on our financial condition.

The credit agreement governing our revolving credit facility contains covenants requiring us to, among other things, maintain a 
minimum ratio of consolidated EBITDA to consolidated interest expense and a maximum ratio of consolidated total indebtedness 
to consolidated EBITDA. In the past, we have obtained amendments from the lenders under the credit agreement which have 
allowed us to comply with the financial covenants, but there can be no assurance that in the future the lenders will agree to such 
amendments, and our inability to comply with the covenants could result in an event of default which, if not cured or waived, 
could have a material adverse effect on our business, financial condition, and operating results.

We are subject to counterparty risk with respect to the convertible note hedge transactions.

As discussed in Note 11. Borrowings to our audited Consolidated Financial Statements under Item 8, "Financial Statements and 
Supplementary Data", we issued convertible senior notes and concurrently entered into convertible note hedge transactions and 
separate warrants. The option counterparties are financial institutions, and we are subject to the risk that one or more of the option 
counterparties may default under the convertible note hedge transactions. Our exposure to the credit risk of the option counterparties 
will not be secured by any collateral. If any of the option counterparties become subject to insolvency proceedings, we will become 
an  unsecured  creditor  in  those  proceedings  with  a  claim  equal  to  our  exposure  at  that  time  under  our  transactions  with  such 
counterparties. Our exposure will depend on many factors but, generally, the increase in our exposure will be correlated to the 
increase in the market price and in the volatility of our common stock. In addition, upon a default by the option counterparties, 
we may suffer adverse tax consequences and more dilution than we currently anticipate with respect to our common stock. We 
can provide no assurances as to the financial stability or viability of the option counterparties.

There are risks associated with our indebtedness, which could have a material adverse effect on our financial condition.

Our outstanding indebtedness and any additional indebtedness we incur may have negative consequences, including:

o

o

o

o

requiring us to use cash to pay the principal of and interest on our indebtedness, thereby reducing the amount of cash 
flow available for other purposes;

limiting  our  ability  to  obtain  additional  financing  for  working  capital,  capital  expenditures,  acquisitions,  stock 
repurchases, dividends, or other general corporate and other purposes;

limiting our flexibility in planning for, or reacting to, changes in our business and our industry; and

increasing our vulnerability to interest rate fluctuations to the extent a portion of our debt has variable interest rates.

Our ability to make payments of principal and interest on our indebtedness depends upon our future performance, which is subject 
to general economic conditions, industry cycles, and financial, business, and other factors, many of which are beyond our control. 
If we are unable to generate sufficient cash flow from operations in the future to service our debt, we may be required to, among 
other things: refinance or restructure all or a portion of our indebtedness; reduce or delay planned capital or operating expenditures; 
or sell selected assets. Such measures might not be sufficient to enable us to service our debt. In addition, any such financing, 
refinancing, or sale of assets might not be available on economically favorable terms or at all, and if prevailing interest rates at 
the time of any such financing and/or refinancing are higher than our current rates, interest expense related to such financing and/
or refinancing would increase. If there are adverse changes in the ratings assigned to our debt securities by credit rating agencies, 
our borrowing costs, our ability to access debt in the future, and/or the terms of the financing could be adversely affected.

Risks Related to Our Corporate Governance

Our business could be negatively affected as a result of the actions of activist or hostile stockholders.

Our business could be negatively affected as a result of stockholder activism, which could cause us to incur significant expense, 
hinder execution of our business strategy, and impact the trading value of our securities. Stockholder activism, which could take 
many forms or arise in a variety of situations, has been increasing in publicly traded companies in recent years and we are subject 
to the risks associated with such activism. Stockholder activism, including potential proxy contests, requires significant time and 
attention  by  management  and  the  Board  of  Directors,  potentially  interfering  with  our  ability  to  execute  our  strategic  plan. 
Additionally, such stockholder activism could give rise to perceived uncertainties as to our future direction, adversely affect our 
relationships with key executives and business partners, and make it more difficult to attract and retain qualified personnel. Also, 
we may be required to incur significant legal fees and other expenses related to activist stockholder matters. Any of these impacts 
could materially and adversely affect our business and operating results. Further, the market price of our common stock could be 
subject to significant fluctuation or otherwise be adversely affected by stockholder activism.

16

 
Certain provisions in our certificate of incorporation, by-laws, and Delaware law may prevent or delay an acquisition of the 
Company, which could decrease the trading price of our common stock.

Each of our certificate of incorporation, our by-laws, and Delaware law, as currently in effect, contain provisions that are intended 
to deter coercive takeover practices and inadequate takeover bids by making such practices or bids unacceptably expensive to the 
bidder and to encourage prospective acquirers to negotiate with our Board of Directors rather than to attempt a hostile takeover. 
These provisions include, among others:

o
o
o
o

o

o

the inability of our stockholders to call a special meeting or act by written consent;
rules regarding how stockholders may present proposals or nominate directors for election at stockholder meetings;
the right of our Board of Directors to issue preferred stock without stockholder approval;
the classification of our Board of Directors and a provision that stockholders may only remove directors for cause, in 
each case until our 2021 annual meeting of stockholders;
the ability of our directors, without a stockholder vote, to fill vacancies on our Board of Directors (including those 
resulting from an enlargement of the Board of Directors); and
the requirement that stockholders holding at least 80% of our voting stock are required to amend certain provisions in 
our certificate of incorporation and our by-laws.

In addition, current Delaware law includes provisions which limit the ability of persons that, without prior board approval, acquire 
more than 15% of the outstanding voting stock of a Delaware corporation from engaging in any business combination with that 
corporation, including by merger, consolidation, or purchases of additional shares, for a three-year period following the acquisition 
by such persons of more than 15% of the corporation’s outstanding voting stock.

In light of present circumstances, we believe these provisions taken as a whole protect our stockholders from coercive or otherwise 
unfair takeover tactics by requiring potential acquirers to negotiate with our Board of Directors and by providing our Board of 
Directors with more time to assess any acquisition proposal. These provisions are not intended to make us immune from takeovers 
or prevent the removal of incumbent directors. However, these provisions could delay or prevent an acquisition that our Board of 
Directors determines is not in the best interests of the Company and all of our stockholders.

ITEM 3. LEGAL PROCEEDINGS

From time to time, we are involved in various legal proceedings and claims arising in the ordinary course of our business, including 
those related to intellectual property, which may be owned by us or others. We own many patents covering products, technology, 
and manufacturing processes. Some of these patents have been and may continue to be challenged by others. In appropriate cases, 
we have taken and will take steps to protect and defend our patents and other intellectual property, including through the use of 
legal proceedings in various jurisdictions around the world. Such steps have resulted in and may continue to result in retaliatory 
legal proceedings, including litigation or other legal proceedings in various jurisdictions and forums around the world alleging 
that we infringe on patents owned by others. The costs of investigations and legal proceedings, particularly multi-forum litigation, 
relating to the enforcement and defense of our intellectual property, may be substantial. Additionally, in multi-forum disputes, we 
may incur adverse judgments with regard to certain claims in certain jurisdictions and forums while still contesting other related 
claims against the same opposing party in other jurisdictions and forums. Although the ultimate outcome of any legal proceeding 
or claim cannot be predicted with certainty, based on present information, including management’s assessment of the merits of 
each claim, we do not expect that any asserted or unasserted legal proceedings or claims, individually or in the aggregate, will 
have a material adverse effect on our cash flow, results of operations, or financial condition.

ITEM 6. SELECTED FINANCIAL DATA

The following table presents selected financial data on a continuing operations basis as derived from our audited Consolidated 
Financial Statements.

The selected financial data includes costs of Knowles’ businesses, which include the allocation of certain corporate expenses from 
our Former Parent through the date of the Separation. We believe that these allocations were made on a reasonable basis. The 
selected historical financial data for the period prior to the Separation may not be indicative of our future performance as an 
independent publicly traded company. The selected financial data should be read in conjunction with "Management's Discussion 
and Analysis of Financial Condition and Results of Operations" included under Item 7 and the Consolidated Financial Statements

(1)  On July 7, 2016, the Company completed the sale of its Speaker and Receiver Product Line. On November 28, 2017, the 
Company completed the sale of its Timing Device Business. All amounts presented are on a continuing operations basis. For 
additional information, refer to Note 2. Disposed and Discontinued Operations to our Consolidated Financial Statements under 
Item 8, "Financial Statements and Supplementary Data."

(2)  On July 1, 2015, the Company completed its acquisition of all of the outstanding shares of common stock of Audience. The 
Consolidated Statements of Earnings and Consolidated Balance Sheets include the results of operations, net assets acquired, 
and depreciation and amortization expense related to Audience since the date of acquisition.

(3)  On January 1, 2018, the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update 
(“ASU”) 2017-07 related to the presentation of net periodic pension and post-retirement benefit cost on a retrospective basis. 
The standard requires components of net benefit cost other than service cost to be presented separately from the service cost 
component and outside of any subtotal of operating income. The impacts of the reclassifications on gross profit were decreases 
of $0.3 million, $0.2 million, $0.2 million, and nil for the years ended December 31, 2017, 2016, 2015, and 2014, respectively. 
For  additional  information,  refer  to  Note  1.  Summary  of  Significant Accounting  Policies  to  our  Consolidated  Financial 
Statements under Item 8, “Financial Statements and Supplementary Data.” 

(4)  On January 27, 2014, we, as a borrower, entered into a $200.0 million five-year senior secured revolving credit facility with a 
group of lenders, as well as a $300.0 million five-year senior secured term loan facility pursuant to a Credit Agreement ("Original 
Credit Agreement"), which are referred to collectively as the “Prior Credit Facilities.” In connection with the Separation, we 
incurred $100.0 million of borrowings under the revolving credit facility and $300.0 million of borrowings under the term loan 
facility, in each case to finance a cash payment to our Former Parent immediately prior to the Separation. On December 31, 
2014, we amended our Prior Credit Facilities to increase the amount of the revolving credit facility in the Original Credit 
Agreement to $350.0 million but incurred no additional borrowings. On July 1, 2015, we amended our Prior Credit Facilities 
to facilitate our ability to consummate the Audience acquisition. We funded the cash portion of the consideration through a 
drawdown of our existing revolving credit facility and cash on hand. On February 9, 2016, the Company entered into a third 
amendment to its Prior Credit Facilities in connection with the Company’s decision to sell the Speaker and Receiver Product 
Line, which also included permanent reduction by the Company of the aggregate revolving commitment under the Original 
Credit Agreement from $350.0 million to $300.0 million. On April 27, 2016, the Company entered into a fourth amendment 
to its Prior Credit Facilities in connection with the Company's offering of the 3.25% Convertible Senior Notes due November 
1, 2021 (the "Notes"). On October 11, 2017, the Company entered into a Revolving Credit Facility Agreement (the "New Credit 
Facility"). The new agreement is being used for working capital and other general corporate purposes of the Company, including 
refinancing of indebtedness under the Company’s Prior Credit Facilities. The New Credit Facility contains a five-year senior 
secured revolving credit facility providing for borrowings in aggregate principal amount of up to $400.0 million. See Item 7. 
"Management's Discussion and Analysis of Financial Condition and Results of Operations—Borrowings" section for additional 
information related to our debt.

(5)  On July 1, 2015, the Company issued 3.2 million shares to former stockholders of Audience and for the conversion of vested 
in-the-money Audience  stock  options.  The  Company  also  converted  unvested  in-the-money Audience  stock  options  and 
restricted stock units for an aggregate of 461,371 shares of its common stock. On February 28, 2014, in connection with the 
Separation, Former Parent stockholders received one share of Knowles common stock for every two shares of Former Parent's 
common stock held as of the record date. Basic and diluted earnings per common share and the average number of common 
shares  outstanding  for  the  periods  prior  to  the  Separation  were  calculated  using  the  number  of  Knowles  common  shares 
outstanding immediately following the Separation. See Note 18. Earnings per Share to our Consolidated Financial Statements 
under Item 8, "Financial Statements and Supplementary Data" for information regarding earnings per common share.

(6)  Also includes current portion of long-term debt and capital lease obligations.

(7)  We use the term “EBIT” throughout this Annual Report on Form 10-K, defined as net earnings plus (i) interest expense, net 
and (ii) income taxes. EBIT is not presented in accordance with accounting principles generally accepted in the United States 
of America ("GAAP" or "U.S. GAAP") and may not be comparable to similarly titled measures used by other companies. We 
use EBIT as a supplement to our GAAP results of operations in evaluating certain aspects of our business, and our Board of 
Directors and executive management team focus on EBIT as a key measure of our performance for business planning purposes. 
This measure assists us in comparing performance between various reporting periods on a consistent basis, as this measure 
removes from operating results the impact of items that, in our opinion, do not reflect our core operating performance. We 
believe that our presentation of EBIT is useful because it provides investors and securities analysts with the same information 
that we use internally for purposes of assessing our core operating performance. For a reconciliation of EBIT to net earnings, 
the most directly related GAAP measure, please see the Statement of Earnings Data table above. The Company does not consider 
EBIT to be a substitute for the information provided by GAAP financial results.

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

The discussion and analysis presented below refer to and should be read in conjunction with our audited Consolidated Financial 
Statements and related notes under Item 8. "Financial Statements and Supplementary Data." The following discussion contains 
forward-looking statements. The matters discussed in these forward-looking statements are subject to risks, uncertainties, and 
other factors that could cause actual results to differ materially from those made, projected, or implied in the forward-looking 
statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this Form 
10-K, particularly in “Risk Factors” and “Cautionary Statement Concerning Forward-Looking Statements.”

Management’s discussion and analysis, which we refer to as “MD&A,” of our results of operations, financial condition, and cash 
flows should be read together with the audited Consolidated Financial Statements and accompanying notes included under Item 
8. "Financial Statements and Supplementary Data," to provide an understanding of our financial condition, changes in financial 
condition,  and  results  of  our  operations.  We  believe  the  assumptions  underlying  the  Consolidated  Financial  Statements  are 
reasonable. However, the Consolidated Financial Statements included herein may not necessarily reflect our results of operations, 
financial position, and cash flows in the future.

As discussed in Note 2. Disposed and Discontinued Operations to our audited Consolidated Financial Statements under Item 8, 
"Financial Statements and Supplementary Data", we completed the sale of our high-end oscillators business ("Timing Device 
Business") in the fourth quarter of 2017 and the sale of our speaker and receiver product line ("Speaker and Receiver Product 
Line") in the third quarter of 2016. Accordingly, the results of operations and related assets and liabilities for the Timing Device 
Business and the Speaker and Receiver Product Line have been reclassified as discontinued operations for all periods presented. 
Unless otherwise indicated, discussion within this MD&A and elsewhere within this Annual Report Form 10-K refers to results 
from continuing operations.

Our Business

We are a market leader and global provider of advanced micro-acoustic, audio processing, and precision device solutions, serving 
the mobile consumer electronics, communications, medical, defense, aerospace, and industrial markets. We use our leading position 
in micro-electro-mechanical systems ("MEMS") microphones and strong capabilities in audio processing technologies to optimize 
audio systems and improve the user experience in mobile, ear, and Internet of Things ("IoT") applications. We are also the leader 
in acoustics components used in hearing aids and have a strong position in high-end capacitors. Our focus on the customer, combined 
with  our  unique  technology,  proprietary  manufacturing  techniques,  rigorous  testing,  and  global  scale,  enables  us  to  deliver 
innovative solutions that optimize the user experience. References to "Knowles," the "Company," "we," "our," or "us" refer to 
Knowles Corporation and its consolidated subsidiaries, unless the context otherwise requires.

Our Business Segments

We are organized into two reportable segments based on how management analyzes performance, allocates capital, and makes 
strategic  and  operational  decisions. These  segments  were  determined  in  accordance  with Accounting  Standards  Codification 
("ASC") 280, Segment Reporting, and are comprised of (i) Audio and (ii) PD. The segments are aligned around similar product 
applications serving our key end markets, to enhance focus on end market growth strategies.

•  Audio Segment

Our Audio group designs and manufactures innovative audio products, including microphones and balanced armature 
speakers, audio processors, and software and algorithms used in applications that serve the mobile, ear, and IoT markets. 
Locations  include  the  sales,  support,  and  engineering  facilities  in  North America,  Europe,  and Asia,  as  well  as  the 
manufacturing facilities in Asia.

• 

PD Segment
Our PD group specializes in the design and delivery of highly engineered capacitors and RF devices for technically 
demanding applications. Our devices are used in applications including power supplies, radar, medical implants, and 
satellites, serving the industrial, defense, aerospace, medical, telecommunications, and automotive markets. Locations 
include the sales, support, engineering, and manufacturing facilities in North America, Europe, and Asia.

We sell our products directly to original equipment manufacturers ("OEMs") and to their contract manufacturers and suppliers 
and to a lesser extent through distributors worldwide.

On January 19, 2018, we acquired substantially all of the assets of Compex Corporation ("Compex") for $18.7 million. The acquired 
business provides single layer electronic components to the telecommunicaton, fiber optics, defense, and aerospace markets. This 
acquisition's operations are included in the PD segment. For additional information, refer to Note 3. Acquisitions to  our Consolidated 
Financial Statements under Item 8, "Financial Statements and Supplementary Data."

On November 28, 2017, we completed the sale of the Timing Device Business, part of the PD segment, for $130.0 million, plus 
purchase  price  adjustments  for  a  net  amount  of  $135.1  million.  For  additional  information,  refer  to  Note  2.  Disposed  and 
Discontinued Operations to our Consolidated Financial Statements under Item 8, "Financial Statements and Supplementary Data."

On January 11, 2017, we completed an acquisition of certain assets of a capacitors manufacturer for cash consideration of $3.7 
million, of which $2.5 million was paid during the first quarter of 2017. An additional $1.0 million was paid during 2018, with 
the remaining $0.2 million to be paid in the first quarter of 2019. This acquisition's operations are included in the PD segment.

On July 7, 2016, we completed the sale of our Speaker and Receiver Product Line for $45.0 million in cash, less purchase price 
adjustments, for a net amount received of $40.6 million. For additional information, refer to Note 2. Disposed and Discontinued 
Operations to our Consolidated Financial Statements under Item 8, "Financial Statements and Supplementary Data."

Results of Operations for the Year Ended December 31, 2018 compared with the Years Ended December 31, 2017 and 
2016

In addition to the GAAP financial measures included herein, we have presented certain non-GAAP financial measures. We use 
non-GAAP measures as supplements to our GAAP results of operations in evaluating certain aspects of our business, and our  
executive management team and Board of Directors focus on non-GAAP items as key measures of our performance for business 
planning purposes. These measures assist us in comparing our performance between various reporting periods on a consistent 
basis, as these measures remove from operating results the impact of items that, in our opinion, do not reflect our core operating 
performance. We believe that our presentation of non-GAAP financial measures is useful because it provides investors and 
securities analysts with the same information that we use internally for purposes of assessing our core operating performance. 
The Company does not consider these non-GAAP financial measures to be a substitute for the information provided by GAAP 
financial results. For a reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financial 
measures, see the reconciliation included herein.

Revenues

2018 Versus 2017

Revenues  for  the  year  ended  December  31,  2018  were  $826.9  million,  compared  with  $744.2  million  for  the  year  ended 
December 31, 2017, an increase of $82.7 million or 11.1%. This change was due to an increase in Audio revenues of $44.8 
million primarily due to higher shipments of MEMS microphones to Chinese OEMs and key North American OEMs. In addition, 
we had higher shipments of intelligent audio solutions and hearing health transducers, partially offset by lower average selling 
prices on mature products, lower royalties as a result of a settlement in 2017, and lower shipments to a key Korean OEM. PD 
revenues had an increase of $37.9 million primarily due to higher capacitor product shipments for the defense, industrial, and 
automotive markets, as well as increased revenues related to our acquisition of Compex.

2017 Versus 2016

Revenues  for  the  year  ended  December  31,  2017  were  $744.2  million,  compared  with  $755.7  million  for  the  year  ended 
December 31, 2016, a decrease of $11.5 million or 1.5%. This change was due to a decrease in Audio revenues of $24.5 million
primarily due to lower average selling prices on mature products in the Audio segment. In addition, shipments of hearing health 
transducers decreased from the prior year as we have been more disciplined with our pricing. The decreases were partially 
offset by the $13.6 million of revenue from a settlement of a royalty dispute and higher shipments of MEMS microphones to 
the IoT market. PD revenues had an increase of $13.0 million primarily due to higher capacitor product shipments for the 
defense, medical, and automotive markets, as well as increased revenues related to our capacitors acquisition in January 2017, 
partially offset by lower pricing.

Cost of Goods Sold

2018 Versus 2017

Cost of goods sold ("COGS") for the year ended December 31, 2018 was $503.9 million, compared with $452.8 million for 
the year ended December 31, 2017, an increase of $51.1 million or 11.3%. This increase was primarily due to higher volume 
from MEMS microphones, capacitor products, and intelligent audio solutions. In addition, there were unfavorable foreign 
currency exchange rate changes and higher ramp costs associated with new product launches at our largest customer, partially 
offset by material cost savings, productivity initiatives, lower production transfer costs, and a settlement of a supplier warranty 
claim.

2017 Versus 2016

COGS for the year ended December 31, 2017 was $452.8 million, compared with $458.2 million for the year ended December 
31, 2016, a decrease of $5.4 million or 1.2%. This decrease was primarily due to favorable impacts from productivity initiatives  
and foreign exchange rate changes, partially offset by lower fixed overhead absorption. In addition, we experienced higher 
capacitor and MEMS microphone shipment volume to the IoT market, along with increases in both production transfer costs  
and restructuring charges.

27

Impairment Charges

In 2017 we recorded total impairment charges of $21.3 million, which relates to a specific product line within the Audio 
segment. We concluded that the projected cash flows from this product line were not sufficient to recover the carrying value 
of the associated long-lived assets. Total impairment charges of $1.4 million were classified as COGS and $19.9 million were 
classified as Operating expenses. For additional information on impairments of long-lived assets, refer to Note 4. Impairments 
to our Consolidated Financial Statements under Item 8, "Financial Statements and Supplementary Data." 

Restructuring Charges

We undertake restructuring programs from time to time to better align our operations with current market conditions. Such 
activities include facility consolidations, headcount reductions, and other measures to further optimize operations. It is likely 
that we will have restructuring charges in the future as we continue to consolidate our manufacturing footprint. Details regarding 
restructuring programs undertaken during the reporting period are as follows:

2018

During the year ended December 31, 2018, we recorded restructuring charges of $2.1 million. The charges consist primarily 
of actions associated with rationalizing the workforce and transferring certain operations of capacitors manufacturing to other 
existing facilities in order to optimize operations. Charges of $0.4 million were classified as COGS and charges of $1.7 million
were classified as Operating expenses.

2017

During the year ended December 31, 2017, we recorded restructuring charges of $10.2 million. The charges consist primarily 
of actions associated with rationalizing the workforce and the continued transfer of our hearing health manufacturing into a 
lower-cost Asian manufacturing facility. Charges of $4.0 million were classified as COGS and charges of $6.2 million were 
classified as Operating expenses.

2016

During the year ended December 31, 2016, we recorded restructuring charges of $10.1 million comprised primarily of actions 
associated with the integration of Audience. Other charges related to actions associated with lowering operating expenses and 
the continued expenses for the transfer of our capacitors business into existing, lower-cost Asian manufacturing facilities.  
Charges of $1.5 million were classified as COGS and charges of $8.6 million were classified as Operating expenses.

Gross Profit and Non-GAAP Gross Profit

2018 Versus 2017

Gross profit for the year ended December 31, 2018 was $322.6 million, compared with $286.0 million for the year ended 
December 31, 2017, an increase of $36.6 million or 12.8%. Gross profit margin (gross profit as a percentage of revenues) for 
the year ended December 31, 2018 was 39.0%, compared with 38.4% for the year ended December 31, 2017. The gross profit 
and margin increased primarily due to higher shipment volumes. In addition, there were material cost savings, productivity 
initiatives, lower production transfer costs, a settlement of a supplier warranty claim, and reduced restructuring charges. The 
increases were partially offset by lower average selling prices on mature products, a settlement of a royalty dispute in 2017, 
foreign currency exchange rate changes, and higher ramp costs associated with new product launches at our largest customer.

Non-GAAP gross profit for the year ended December 31, 2018 was  $327.0 million, compared with $299.9 million for the year 
ended December 31, 2017, an increase of $27.1 million or 9.0%. Non-GAAP gross profit margin (non-GAAP gross profit as 
a percentage of revenues) for the year ended December 31, 2018 was 39.5%, as compared with 40.3% for the year ended 
December 31, 2017. Non-GAAP gross profit increased primarily due to higher shipment volumes. In addition, there were 
material cost savings, productivity initiatives, and a settlement of a supplier warranty claim. The increases were partially offset 
by lower average selling prices on mature products, a settlement of a royalty dispute in 2017, foreign currency exchange rate 
changes, and higher ramp costs associated with new product launches at our largest customer. Non-GAAP gross profit margin 
decreased primarily due to a settlement of a royalty dispute in 2017. 

28

2017 Versus 2016

Gross profit for the year ended December 31, 2017 was $286.0 million, compared with $295.7 million for the year ended 
December 31, 2016, a decrease of $9.7 million or 3.3%. Gross profit margin for the year ended December 31, 2017 was 38.4%, 
compared with 39.1% for the year ended December 31, 2016. The gross profit and margin decreased primarily due to lower 
average selling prices on mature products, lower fixed overhead absorption, higher production transfer costs, and increased 
restructuring charges. The decreases were partially offset by favorable impacts from productivity initiatives, a settlement of a 
royalty dispute, and foreign currency exchange rate changes.

Non-GAAP gross profit for the year ended December 31, 2017 was $299.9 million, compared with $302.0 million for the year 
ended December 31, 2016, a decrease of $2.1 million or 0.7%. Non-GAAP gross profit margin for the year ended December 
31, 2017 was 40.3%, as compared with 40.0% for the year ended December 31, 2016. The Non-GAAP gross profit decreased 
primarily due to lower average selling prices on mature products and lower fixed overhead absorption. The decrease was 
partially  offset  by  favorable  impacts  from  productivity  initiatives,  a  settlement  of  a  royalty  dispute,  and  foreign  currency 
exchange  rate  changes.  Non-GAAP  gross  profit  margin  increased  slightly  as  non-GAAP  gross  profit  remained  relatively 
consistent with prior year while revenues decreased $11.5 million. 

Research and Development Expenses

2018 Versus 2017

Research and development expenses for the years ended December 31, 2018 and 2017 were $100.6 million and $93.4 million, 
respectively. Research and development expenses as a percentage of revenues for the years ended December 31, 2018 and 
2017 were 12.2% and 12.6%, respectively. The increase in research and development expenses was driven by compensation 
increases and an increase in new product development spending.

2017 Versus 2016

Research and development expenses for the years ended December 31, 2017 and 2016 were $93.4 million and $92.0 million, 
respectively. Research and development expenses as a percentage of revenues for the years ended December 31, 2017 and 
2016 were 12.6% and 12.2%, respectively. The increase in research and development expenses was driven by compensation 
increases, partially offset by lower headcount.

Selling and Administrative Expenses

2018 Versus 2017

Selling and administrative expenses for the year ended December 31, 2018 were $142.5 million, compared with $126.6 million
for the year ended December 31, 2017, an increase of $15.9 million or 12.6%. Selling and administrative expenses as a percentage 
of revenues for the year ended December 31, 2018 were 17.2%, compared with 17.0% for the year ended December 31, 2017.  
The increase in selling and administrative expenses was primarily driven by incentive compensation increases, an increase in 
legal fees, and the acquisition of Compex, partially offset by lower intangible amortization costs. The increase in legal fees 
was primarily due to a settlement of a royalty dispute in 2017.

2017 Versus 2016

Selling and administrative expenses for the year ended December 31, 2017 were $126.6 million, compared with $149.9 million
for the year ended December 31, 2016, a decrease of $23.3 million or 15.5%. Selling and administrative expenses as a percentage 
of revenues for the year ended December 31, 2017 were 17.0%, compared with 19.8% for the year ended December 31, 2016.
The decrease in selling and administrative expenses and as a percentage of revenues was primarily driven by lower intangible 
amortization costs, benefits of our cost reduction initiatives, and a reduction in legal fees. The reduction in legal fees was driven 
by a settlement of a royalty dispute, which included a $5.6 million allocation against previously incurred expenses.

29

Earnings and Adjusted Earnings from Continuing Operations Before Interest and Income Taxes

2018 Versus 2017

Earnings before interest and income taxes ("EBIT") from continuing operations for the year ended December 31, 2018 was 
$77.1 million, compared with $40.0 million for the year ended December 31, 2017, an increase of $37.1 million or 92.8%. 
EBIT margin (EBIT from continuing operations as a percentage of revenues) for the year ended December 31, 2018 was 9.3%, 
as compared with 5.4% for the year ended December 31, 2017. This increase was primarily due to higher gross profit and the  
absence of impairment charges in 2018, partially offset by higher operating expenses due to incentive compensation increases, 
an increase in legal fees due to a settlement of a royalty dispute in 2017, and the acquisition of Compex.

Adjusted earnings before interest and income taxes ("Adjusted EBIT") from continuing operations for the year ended December 
31, 2018 was $117.2 million, compared with $110.6 million for the year ended December 31, 2017,  an increase of $6.6 million
or 6.0%. Adjusted EBIT margin (adjusted EBIT from continuing operations as a percentage of revenues) for the year ended 
December 31, 2018 was 14.2%, as compared with 14.9% for the year ended December 31, 2017. This Adjusted EBIT increase 
was primarily due to higher gross profit, partially offset by higher operating expenses due to compensation increases, an increase 
in legal fees due to a settlement of a royalty dispute in 2017, and the acquisition of Compex. The Adjusted EBIT margin decrease 
is primarily due to a settlement of a royalty dispute in 2017, and higher operating expenses due to incentive compensation 
increases.

2017 Versus 2016

EBIT from continuing operations for the year ended December 31, 2017 was $40.0 million, compared with $48.5 million for 
the year ended December 31, 2016, a decrease of $8.5 million or 17.5%. EBIT margin for the year ended December 31, 2017 
was 5.4%, as compared to 6.4% for the year ended December 31, 2016. This decrease was primarily due to lower gross profit 
and higher impairment charges in Operating expense, partially offset by lower intangible amortization costs, benefits of our 
operating cost reduction initiatives, and the reduction in legal fees driven by a settlement of a royalty dispute.

Adjusted EBIT from continuing operations for the  year ended December 31, 2017 was $110.6 million, compared with $99.7 
million for the year ended December 31, 2016, an increase of $10.9 million or 10.9%. Adjusted EBIT margin for the year ended 
December 31, 2017 was 14.9%, as compared with 13.2% for the year ended December 31, 2016. The increase is primarily due 
to lower non-GAAP operating expenses, driven by our operating cost reduction initiatives, and the reduction in legal fees driven 
by a settlement of a royalty dispute.

Interest Expense, net

2018 Versus 2017

Interest expense, net for the year ended December 31, 2018 was $16.0 million, compared with $20.6 million for the year ended 
December 31, 2017, a  decrease of $4.6 million or 22.3%. The decrease in interest expense is primarily due to lower outstanding 
borrowings. For additional information on borrowings and interest expense, refer to Note 11. Borrowings to our Consolidated 
Financial Statements under Item 8, "Financial Statements and Supplementary Data."

2017 Versus 2016

Interest expense, net for the year ended December 31, 2017 was $20.6 million, compared with $20.4 million for the year ended 
December 31, 2016, an increase of $0.2 million or 1.0%. The increase in interest expense is primarily due to non-cash interest 
expense related to the Company's issuance of $172.5 million aggregate principal amount of 3.25% convertible senior notes 
due November 1, 2021 in a private placement in May 2016 (the "Notes") and higher interest rates, partially offset by lower 
outstanding borrowings. For additional information on borrowings and interest expense, refer to Note 11. Borrowings to our 
Consolidated Financial Statements under Item 8, "Financial Statements and Supplementary Data."

30

(Benefit from) Provision for Income Taxes and Non-GAAP Provision for Income Taxes

2018 Versus 2017

The effective tax rate ("ETR") for the year ended December 31, 2018 was a 7.4% benefit, compared with a 66.5% provision
for the year ended December 31, 2017. The change in the ETR is primarily due to the mix of earnings by taxing jurisdictions 
and the Tax Reform Act. As a result of the Internal Revenue Service ("IRS") approval for an entity classification election 
received during the fourth quarter of 2018, we recorded a $17.8 million reduction to our transition tax liability.

The ETR for the years ended December 31, 2018 and 2017 was favorably impacted by two tax holidays granted to us by 
Malaysia. For additional information on these tax holidays, see Note 12. Income Taxes to our Consolidated Financial Statements 
under Item 8, “Financial Statements and Supplementary Data."

The non-GAAP ETR for the year ended December 31, 2018 was a 12.1% provision, compared with a 15.5% provision for the 
year ended December 31, 2017. The change in the non-GAAP ETR was due to the mix of earnings by taxing jurisdictions.

The ETR and non-GAAP ETR deviate from the statutory U.S. federal income tax rate, mainly due to the taxing jurisdictions 
in which we generate taxable income or loss, the favorable impact of our tax holidays in Malaysia, and judgments as to the 
realizability of our deferred tax assets. A significant portion of our pre-tax income is not subject to tax as a result of our tax 
holidays in Malaysia, subject to our satisfaction of certain conditions that we expect to continue to satisfy. Unless extended or 
otherwise renegotiated, our existing tax holidays in Malaysia will expire December 31, 2021. During 2016, the Company 
applied for and received final approval to modify the terms of its main tax holiday in Malaysia, reducing the rate to 7.2% versus 
the statutory rate of 24.0%, effective January 1, 2017 through December 31, 2021. The U.S. operations were in a cumulative 
loss position as of December 31, 2018 and 2017, respectively. Based on this, and other relevant information, the Company 
concluded that tax losses and deferred tax assets generated in the U.S. would not be benefited currently or in the future.

2017 Versus 2016

The ETR for the year ended December 31, 2017 was a 66.5% provision, compared with a 29.5% provision for the year ended 
December 31, 2016. The change in the ETR is primarily due to the mix of earnings by taxing jurisdictions,  the change to the 
terms of our tax holiday in Malaysia, and the Tax Reform Act. We recorded a provisional tax benefit of $11.7 million related 
to the reassessment of the beginning of the year valuation allowance, and a $5.6 million provisional benefit related to the 
remeasurement of our net deferred tax liability as a result of the Tax Reform Act. We also recorded a provisional tax expense 
of $56.0 million, net of expected foreign tax credits, related to the deemed repatriation of unremitted earnings for foreign 
subsidiaries,  which  was  partially  offset  by  the  use  of  existing  tax  attributes  primarily  consisting  of  net  operating  loss 
carryforwards and research and development tax credits.

The ETR for the years ended December 31, 2017 and 2016 was favorably impacted by two tax holidays granted to us by 
Malaysia. The ETR for the year ended December 31, 2017 was unfavorably impacted by losses incurred in jurisdictions with 
zero tax benefit recorded. The ETR for the year ended December 31, 2016 was unfavorably impacted by valuation allowances 
recorded in certain jurisdictions, primarily the U.S. and the United Kingdom ("U.K").

The non-GAAP ETR for the year ended December 31, 2017 was a 15.5% provision, compared with a 3.8% provision for the 
year ended December 31, 2016. The change in the non-GAAP ETR was due to the mix of earnings by taxing jurisdictions.

The ETR and non-GAAP ETR deviate from the statutory U.S. federal income tax rate, mainly due to the taxing jurisdictions 
in which we generate taxable income or loss, the favorable impact of our tax holidays in Malaysia, and judgments as to the 
realizability of our deferred tax assets.

Earnings (Loss) from Discontinued Operations, net

2018 Versus 2017

The earnings from discontinued operations was $2.1 million net of tax for the year ended December 31, 2018, compared with 
earnings of $61.8 million for the year ended December 31, 2017. The change in discontinued operations was primarily driven 
by the sale of our Timing Device Business on November 28, 2017, for which we recognized a $62.3 million pre-tax gain in 
2017 and a $1.8 million favorable purchase price adjustment in 2018. 

31

2017 Versus 2016

The earnings from discontinued operations was $61.8 million net of tax for the year ended December 31, 2017 compared with 
a loss of $62.1 million for the year ended December 31, 2016 . The earnings in 2017 primarily relates to the $62.3 million pre-
tax gain on sale of our Timing Device Business. The 2016 loss was primarily related to the high unabsorbed fixed costs in our 
Speaker and Receiver Product Line due to lower production activity and the $25.6 million pre-tax loss on the sale of our Speaker 
and Receiver Product Line.

Diluted Earnings per Share from Continuing Operations and Non-GAAP Diluted Earnings per Share from Continuing 
Operations

2018 Versus 2017

Diluted earnings per share from continuing operations was $0.72 for the year ended December 31, 2018, compared with $0.07
for the year ended December 31, 2017. The increase in diluted earnings per share was primarily due to higher EBIT.

Non-GAAP diluted earnings per share from continuing operations for the year ended December 31, 2018 was $1.01, compared 
with $0.88 for the year ended December 31, 2017. The increase in non-GAAP diluted earnings per share was primarily due to 
higher Adjusted EBIT.

2017 Versus 2016

Diluted earnings per share from continuing operations was $0.07 for the year ended December 31, 2017, compared with $0.22
for the year ended December 31, 2016. The decrease in diluted earnings per share was primarily due to lower EBIT.

Non-GAAP diluted earnings per share from continuing operations for the year ended December 31, 2017 was $0.88, compared 
with $0.89 for the year ended December 31, 2016. The decrease in non-GAAP diluted earnings per share was mainly driven 
by higher adjusted EBIT, which was more than offset by a higher effective tax rate.

(1)  In addition to the GAAP financial measures included herein, Knowles has presented certain non-GAAP financial measures 
that exclude certain amounts that are included in the most directly comparable GAAP measures. Knowles believes that non-
GAAP measures are useful as supplements to its GAAP results of operations to evaluate certain aspects of its operations 
and  financial  performance,  and  its  management  team  primarily  focuses  on  non-GAAP  items  in  evaluating  Knowles' 
performance  for  business  planning  purposes.  Knowles  also  believes  that  these  measures  assist  it  with  comparing  its 
performance between various reporting periods on a consistent basis, as these measures remove from operating results the 
impact of items that, in Knowles' opinion, do not reflect its core operating performance. Knowles believes that its presentation 
of non-GAAP financial measures is useful because it provides investors and securities analysts with the same information 
that Knowles uses internally for purposes of assessing its core operating performance.

(2)  Production transfer costs represent duplicate costs incurred to migrate manufacturing to facilities primarily in Asia. These 
amounts are included in the corresponding Gross profit and Earnings from continuing operations before interest and income 
taxes for each period presented.

(3)  In 2018, Other expenses in Gross profit  and Operating expenses represent expenses related to acquisitions and the remaining 
Other expenses represent an adjustment to pre-spin-off pension obligations. In 2017, Other primarily represents expenses 
related to the acquisition of certain assets of a capacitors manufacturer. In 2016, Other primarily represents a gain on the 
sale of investment related to a non-controlling interest in a MEMs timing device company, partially offset by expenses 
related to the Audience acquisition. 

(4)  Under GAAP, certain convertible debt instruments that may be settled in cash (or other assets) upon conversion are required 
to be separately accounted for as liability (debt) and equity (conversion option) components of the instrument in a manner 
that reflects the issuer’s nonconvertible debt borrowing rate. Accordingly, for GAAP purposes we are required to recognize 
imputed interest expense on the Company’s $172.5 million of convertible senior notes due 2021 that were issued in a private 
placement in May 2016. The imputed interest rate is 8.12% for the convertible notes due 2021, while the actual coupon 
interest rate of the notes was 3.25%. The difference between the imputed interest expense and the coupon interest expense 
is excluded from management’s assessment of the Company’s operating performance because management believes that 
this non-cash expense is not indicative of its core, ongoing operating performance.

(5)  Income tax effects of non-GAAP reconciling adjustments are calculated using the applicable tax rates in the jurisdictions 
of the underlying adjustments. Adjustments are also made to exclude certain impacts of the Tax Reform Act and the resulting 
consequences that were accounted for as uncertain tax positions.

(6)  The Non-GAAP reconciling adjustments are those adjustments made to reconcile Earnings from continuing operations 

before interest and income taxes to Adjusted earnings from continuing operations before interest and income taxes.

(7)  The number of shares used in the diluted per share calculations on a non-GAAP basis excludes the impact of stock-based 
compensation expense expected to be incurred in future periods and not yet recognized in the financial statements, which 
would otherwise be assumed to be used to repurchase shares under the GAAP treasury stock method.

Revenues

2018 Versus 2017

Audio revenues were $682.2 million for the year ended December 31, 2018, compared with $637.4 million for the year ended 
December  31,  2017,  an  increase  of  $44.8  million  or  7.0%.  Revenues  increased  primarily  due  to  higher  shipments  of  MEMS 
microphones to Chinese OEMs and key North American OEMs. In addition, we had higher shipments of intelligent audio solutions 
and hearing health transducers, partially offset by lower average selling prices on mature products, lower royalties as a result of 
a settlement in 2017, and lower shipments to a key Korean OEM.

2017 Versus 2016

Audio revenues were $637.4 million for the year ended December 31, 2017, compared with $661.9 million for the year ended 
December 31, 2016, a decrease of $24.5 million or 3.7%. Revenues decreased primarily due to lower average selling prices on 
mature products in the Audio segment. In addition, shipments of hearing health transducers decreased from the prior year as we 
have been more disciplined with our pricing. The decreases were partially offset by the $13.6 million of revenue from a settlement 
of a royalty dispute and higher shipments of MEMS microphones to the IoT market and higher shipments of MEMS microphones 
to the IoT market.

Earnings and Adjusted Earnings from Continuing Operations Before Interest and Income Taxes

2018 Versus 2017

Audio EBIT from continuing operations was $105.7 million for the year ended December 31, 2018, compared with $76.1 million
for the year ended December 31, 2017, an increase of $29.6 million or 38.9%. EBIT margin for the year ended December 31, 2018
was 15.5%, compared to 11.9% for the year ended December 31, 2017. The increase was primarily due to higher shipment volumes, 
the absence of impairment charges in 2018, material cost savings, productivity initiatives, reduced restructuring charges, lower 
production transfer costs, and a settlement of a supplier warranty claim. The increases were partially offset by lower average selling 
prices on mature products, a settlement of a royalty dispute in 2017, foreign currency exchange rate changes, and higher ramp 
costs associated with new product launches at our largest customer.

Audio Adjusted EBIT was $126.2 million for the year ended December 31, 2018, compared with $129.8 million for the year ended 
December 31, 2017, a decrease of $3.6 million or 2.8%. Adjusted EBIT margin for the year ended December 31, 2018 was 18.5%, 
compared with 20.4% for the year ended December 31, 2017. The decrease was primarily due to lower average selling prices on 
mature products, a settlement of a royalty dispute in 2017, foreign currency exchange rate changes, and higher ramp costs associated 
with new product launches at our largest customer. The decreases were partially offset by higher shipment volumes, material cost 
savings, productivity initiatives, and a settlement of a supplier warranty claim. The Adjusted EBIT margin decreased primarily 
due to a settlement of a royalty dispute in 2017.

2017 Versus 2016

Audio EBIT from continuing operations was $76.1 million for the year ended December 31, 2017, compared with $88.8 million
for the year ended December 31, 2016, a decrease of $12.7 million or 14.3%. EBIT margin for the year ended December 31, 2017
was 11.9%, compared to 13.4% for the year ended December 31, 2016. The decrease was primarily due to lower average selling 
prices on mature products, higher impairments of long-lived assets, lower fixed overhead absorption, higher production transfer 
costs, increased stock-based compensation, and higher restructuring charges. These decreases were partially offset by benefits 
from our productivity initiatives, $19.2 million received from a settlement of a royalty dispute, lower amortization expenses, 
benefits of our operating cost reduction initiatives, favorable impacts from foreign currency exchange rate changes, and higher 
shipments of MEMS microphones.

Audio Adjusted EBIT was $129.8 million for the year ended December 31, 2017, compared with $125.2 million for the year ended 
December 31, 2016, an increase of $4.6 million or 3.7%. Adjusted EBIT margin for the year ended December 31, 2017 was 20.4%, 
compared with 18.9% for the year ended December 31, 2016. The increase was primarily due to benefits from our productivity 
initiatives,  $19.2  million  received  from  a  settlement  of  a  royalty  dispute,  benefits  of  our  operating  cost  reduction  initiatives, 
favorable impacts from foreign currency exchange rate changes, and higher shipments of MEMS microphones. These increases 
were partially offset by lower average selling prices on mature products and lower fixed overhead absorption.

31, 2016, an increase of $13.0 million or 13.9%. Revenues increased due to higher capacitor product shipments primarily for the 
defense, medical, and automotive markets, as well as increased revenues related to our capacitors acquisition in January 2017, 
partially offset by lower pricing.

Earnings and Adjusted Earnings from Continuing Operations Before Interest and Income Taxes

2018 Versus 2017

PD EBIT from continuing operations was $27.5 million for the year ended December 31, 2018, compared with $19.2 million for 
the year ended December 31, 2017, an increase of $8.3 million or 43.2%. EBIT margin for the year ended December 31, 2018
was 19.0%, compared with 18.0% for the year ended December 31, 2017. The increases were primarily due to higher gross profit 
as a result of increased shipments and our acquisition of Compex, partially offset by higher operating expenses due to compensation 
increases and our acquisition of Compex. In addition, an unfavorable adjustment was recorded to a pre-spin-off pension obligation 
in the second quarter of 2018.

37

 
PD Adjusted EBIT was $33.9 million for the year ended December 31, 2018, compared with $21.1 million for the year ended 
December 31, 2017, an increase of $12.8 million or 60.7%. Adjusted EBIT margin for the year ended December 31, 2018 was 
23.4%, compared with 19.8% for the year ended December 31, 2017. The increases were primarily due to higher gross profit as 
a result of increased shipments and our acquisition of Compex, partially offset by higher operating expenses due to compensation 
increases and our acquisition of Compex.

2017 Versus 2016

PD EBIT from continuing operations was $19.2 million for the year ended December 31, 2017, compared with $12.4 million for 
the year ended December 31, 2016, an increase of $6.8 million or 54.8%. EBIT margin for the year ended December 31, 2017
was 18.0%, compared with 13.2% for the year ended December 31, 2016. The increases were primarily due to benefits from 
increased shipments, productivity initiatives, lower restructuring charges, and production transfer costs, along with realized cost 
savings from our production transfers to lower-cost Asian manufacturing facilities, partially offset by lower pricing and increased 
operating expenses.

PD Adjusted EBIT was $21.1 million for the year ended December 31, 2017, compared with $16.4 million for the year ended 
December 31, 2016, an increase of $4.7 million or 28.7%. Adjusted EBIT margin for the year ended December 31, 2017 was 
19.8%, compared with 17.5% for the year ended December 31, 2016. The increases were primarily due to benefits from increased 
shipments, productivity initiatives, and realized cost savings from our production transfers to lower-cost Asian manufacturing 
facilities, partially offset by lower pricing and increased operating expenses.

Financial Condition

Historically, we have generated and expect to continue to generate positive cash flow from operations. Our ability to fund our 
operations and capital needs will depend on our ongoing ability to generate cash from operations and access to capital markets. 
We believe that our future cash flow from operations and access to capital markets will provide adequate resources to fund our 
working capital needs, dividends (if any), capital expenditures, and strategic investments. We have secured a revolving line of 
credit in the United States from a syndicate of commercial banks to provide additional liquidity. Furthermore, if we were to require 
additional cash above and beyond our cash on the balance sheet, the free cash flow generated by the business, and availability 
under our revolving credit facility, we would most likely seek to raise long-term financing through the U.S. debt or bank markets.

In May 2016, we sold the Notes and concurrently entered into convertible note hedge transactions and separate warrants. The 
Notes will mature in November 2021, unless earlier repurchased by us or converted pursuant to their terms. The Notes are unsecured, 
senior obligations and interest is payable semiannually in arrears. The Notes will be convertible into cash, shares of our common 
stock, or a combination thereof, at our election. We have primarily used the net proceeds to reduce borrowings outstanding under 
our term loan facility. For additional information, refer to Note 11. Borrowings to our Consolidated Financial Statements under 
Item 8, "Financial Statements and Supplementary Data."

On July 7, 2016, we completed the sale of our Speaker and Receiver Product Line for $45.0 million in cash, less purchase price 
adjustments for a net amount received of $40.6 million. We used the net proceeds to reduce borrowings outstanding under our 
revolving credit facility. Refer to Note 2. Disposed and Discontinued Operations to our Consolidated Financial Statements under 
Item 8, "Financial Statements and Supplementary Data" for additional information.

On January 11, 2017, we completed an acquisition of certain assets of a capacitors manufacturer for cash consideration of $3.7 
million, of which $2.5 million was paid during 2017. An additional $1.0 million was paid during the year ended December 31, 
2018, with the remaining $0.2 million to be paid in the first quarter of 2019. This acquisition's operations are included in the PD 
segment.  Refer  to  Note  3. Acquisitions  to  our  Consolidated  Financial  Statements  under  Item  8,  "Financial  Statements  and 
Supplementary Data" for additional information.

On  October  11,  2017,  we  entered  into  the  New  Credit  Facility.  Refer  to  Note  11.  Borrowings  to  our  Consolidated  Financial 
Statements under Item 8, "Financial Statements and Supplementary Data" for additional information.

On November 28, 2017, we completed the sale of the Timing Device Business, part of the PD segment, for $130.0 million, subject 
to purchase price adjustments. Refer to Note 2. Disposed and Discontinued Operations to our Consolidated Financial Statements 
under Item 8, "Financial Statements and Supplementary Data" for additional information.

38

On January 19, 2018, we acquired substantially all of the assets of Compex Corporation ("Compex") for $18.7 million. The acquired 
business provides single layer electronic components to the telecommunicaton, fiber optics, defense, and aerospace markets. This 
acquisition's operations are included in the PD segment. For additional information, refer to Note 3. Acquisitions to  our Consolidated 
Financial Statements under Item 8, "Financial Statements and Supplementary Data."

Our ability to make payments on and to refinance our indebtedness, as well as any debt that we may incur in the future, will depend 
on our ability in the future to generate cash from operations and financings. Due to the global nature of our operations, a significant 
portion of our cash is generated and held outside the United States. Our cash and cash equivalents totaled $73.5 million and $111.7 
million at December 31, 2018 and 2017, respectively. Of these amounts, cash held by our non-U.S. operations totaled $55.3 million
and $75.7 million as of December 31, 2018 and 2017, respectively.

To the extent we repatriate these funds to the U.S., we may be required to pay income taxes in certain U.S. states and applicable 
foreign withholding taxes on those amounts during the period when such repatriation occurs. Management will continue to reassess 
our need to repatriate the earnings of our foreign subsidiaries.

Cash Flow Summary

Cash provided by operating activities in 2018 increased $5.6 million compared to 2017. The increase is primarily due to improved 
earnings before income taxes and discontinued operations, which was largely driven by higher revenues. In addition, while our 
inventory  balances  have  increased  from  2017,  we  have  invested  at  a  lower  rate  when  compared  to  the  prior  year.  Our  lower 
investment rate in inventories is primarily the result of completing our transfer of certain hearing health production from China 
to our facility in the Philippines, partially offset by the increased PD production to support our growth in shipments. The increases 
were partially offset by the timing of payments to satisfy our accounts payable obligations, payments against our restructuring 
obligations, an increase in cash taxes paid, and the settlement of a warranty claim. 

Cash provided by operating activities in 2017 decreased $14.6 million compared to 2016, primarily due to a higher investment in 
inventory, partially offset by an increase in accounts payables. During 2017, inventories increased to support the launch of new 
handsets at our largest customer and in conjunction with the transfer of certain hearing health production from China to our facility 
in the Philippines.

Investing Activities

Cash provided by and used in investing activities results primarily from cash inflows from the sale of businesses and outflows for 
capital expenditures, acquisitions, and investment activity.

Capital spending. Capital expenditures, primarily to support capacity expansion, innovation, and cost savings, were $80.1 million, 
$51.6 million, and $38.7 million for the years ended December 31, 2018, 2017, and 2016, respectively. The largest drivers of the 
capital expenditures have been related to ongoing investments in MEMS manufacturing capacity expansion to support growth in 
the handset, ear, and IoT markets, investments in new product launches, and manufacturing footprint optimization projects.

39

 
 
 
Sales of business, acquisitions, and investments. We received escrow proceeds of $10.0 million from the prior year sale of our 
Timing Device Business and acquired Compex during 2018. We received net proceeds of $123.1 million from the sale of our 
Timing Device Business and acquired certain assets of a capacitors manufacturer during 2017. We received net proceeds of $40.6 
million from the sale of our Speaker and Receiver Product Line during 2016. 

Financing Activities

Cash used in financing activities during 2018 is primarily related to the net payments under our revolving credit facility of $41.7 
million and the $4.7 million payment of taxes related to net share settlement of equity awards. Cash used in financing activities 
during 2017 is primarily related to the $118.5 million principal payment on our term loan and the $5.1 million payment of taxes 
related to net share settlement of equity awards, partially offset by net borrowings under our revolving credit facility of $5.7 million 
and the $3.3 million of proceeds received for option exercises. Cash used in financing activities during 2016 primarily related to 
$166.5 million in principal payments on our term loan, a $44.5 million purchase of convertible note hedges, $100.0 million in net 
payments on our revolving credit facility, and $6.7 million of debt issuance costs, partially offset by proceeds of $172.5 million 
from the issuance of the Notes and the $39.1 million of proceeds from the issuance of warrants. For additional information on our 
debt, see Note 11. Borrowings to our Consolidated Financial Statements under Item 8, "Financial Statements and Supplementary 
Data."

Liquidity and Capital Resources

Free Cash Flow

In addition to measuring our cash flow generation and usage based upon the operating, investing, and financing classifications 
included in the Consolidated Statements of Cash Flows, we also measure free cash flow and free cash flow as a percentage of 
revenues. Free cash flow is calculated as cash flow provided by operating activities less capital expenditures. Our management 
believes these measures are useful in measuring our cash generated from operations that is available to repay debt, pay dividends, 
fund acquisitions, and repurchase Knowles’ common stock. Free cash flow and free cash flow as a percentage of revenues are not 
presented in accordance with GAAP and may not be comparable to similarly titled measures used by other companies in our 
industry. As such, free cash flow and free cash flow as a percentage of revenues should not be considered in isolation from, or as 
an alternative to, any other liquidity measures determined in accordance with GAAP.

Our businesses tend to have stronger revenues in the third and fourth quarters of each fiscal year. This is particularly true of those 
businesses that serve the consumer electronics market. Our businesses tend to have short product cycles due to the highly technical 
nature of the industries they serve, which can result in new OEM product launches that can impact quarterly revenues, earnings, 
and cash flow. 

The following table reconciles our free cash flow to cash flow provided by operating activities:

million, representing 5.5% of revenues, and free cash flow in 2016 of $68.8 million, or 9.1% of revenues. The decrease in free 
cash flow in 2018 compared to 2017 was primarily due to increased capital expenditures to support our manufacturing capacity 
expansion. The decrease in free cash flow in 2017 compared to 2016 was primarily due to increased capital expenditures to support 
our manufacturing capacity expansion and a higher investment in inventories.

In 2019, we expect capital expenditures to be in the range of 6.0% to 8.0% of revenues.

Borrowings

In May 2016, we issued $172.5 million aggregate principal amount of 3.25% convertible senior notes due November 1, 2021, 
unless earlier repurchased by us or converted pursuant to their terms. Interest is payable semiannually in arrears on May 1 and 
November 1 of each year, commencing on November 1, 2016. The Notes are governed by an indenture (the "Indenture") between 
us, as issuer, and U.S. Bank National Association as trustee. Upon conversion, we will pay or deliver cash, shares of our common 
stock or a combination of cash and shares of common stock, at our election. The initial conversion rate is 54.2741 shares of common 
stock per  $1,000 principal amount of Notes. The initial conversion price is $18.4250 per share of common stock. The conversion 
rate will be subject to adjustment upon the occurrence of certain specified events but will not be adjusted for accrued and unpaid 
interest. In addition, upon the occurrence of a make-whole fundamental change (as defined in the Indenture), we may be required, 
in certain circumstances, to increase the conversion rate by a number of additional shares for a holder that elects to convert the 
Notes in connection with such make-whole fundamental change.

On October 11, 2017, Knowles entered into the New Credit Facility which contains a five-year senior secured revolving credit 
facility providing for borrowings in an aggregate principal amount at any time outstanding not to exceed $400.0 million. The New 
Credit Facility replaced the Company's Prior Credit Facilities discussed in Note 11. Borrowings to our Consolidated Financial 
Statements under Item 8, "Financial Statements and Supplementary Data." Up to $100.0 million of the New Credit Facility will 
be available in Euro, Sterling, and other currencies requested by the Company and agreed to by each Lender and up to $50.0 
million of the New Credit Facility will be made available in the form of letters of credit denominated in any currencies agreed by 
the issuing bank. The New Credit Facility serves as refinancing of indebtedness under and terminates the Prior Credit Facilities.

41

At any time during the term of the New Credit Facility, the Company will be permitted to increase the commitments under the 
New Credit Facility or to establish one or more incremental term loan facilities under the New Credit Facility in an aggregate 
principal amount not to exceed $200.0 million for all such incremental facilities.

Commitments under the New Credit Facility will terminate, and loans outstanding thereunder will mature, on October 11, 2022; 
provided, that if all the Company’s 3.25% Convertible Senior Notes Due November 1, 2021 have not been repaid, refinanced and/
or converted to common stock of the Company by April 30, 2021, then the commitments under the New Credit Facility will 
terminate, and the loans outstanding thereunder will mature, on such earlier date.

The interest rates under the New Credit Facility will be, at the Borrowers’ option (1) LIBOR (or, in the case of borrowings under 
the New Credit Facility denominated in Euro, EURIBOR) plus the rates per annum determined from time to time based on the 
Company's total indebtedness to Consolidated EBITDA ratio as of the end of and for the most recent period of four fiscal quarters 
for which financial statements have been delivered (the “Applicable Rate”); or (2) in the case of borrowings denominated in U.S. 
dollars, alternate base rate (“ABR”); provided, however, that any swingline borrowings shall bear interest at the rate applicable to 
ABR borrowings or, prior to the purchase of participations in such borrowings by the Lenders, at such other rate as shall be agreed 
between the Company and the swingline lender.

The interest rate under the New Credit Facility is variable based on LIBOR at the time of the borrowing and the Company’s leverage 
as measured by a total indebtedness to Consolidated EBITDA ratio. Based upon the Company’s total indebtedness to Consolidated 
EBITDA ratio, the Company’s borrowing rate could range from LIBOR + 1.25% to LIBOR + 2.25%. In addition, a commitment 
fee accrues on the average daily unused portion of the New Credit Facility at a rate of 0.20% to 0.35%.

We have the right to prepay borrowings under the facilities and to reduce the unutilized portion of the New Credit Facility, in each 
case, at any time without premium or penalty (except for Eurodollar breakage fees, if any). We are required to prepay borrowings 
under the term facility with 100% of the net cash proceeds of sales or dispositions of assets or other property (including, among 
others, the proceeds of issuances of equity interests by subsidiaries), subject to certain reinvestment rights and other exceptions. 
As we are exposed to market risk for changes in interest rates based on the structure of our indebtedness, we entered into an interest 
rate swap on November 12, 2014 to convert variable interest rate payments into a fixed rate on a notional amount of $100.0 million 
of debt for monthly interest payments starting in January 2016 and ending in July 2018. In December 2017, the Company entered 
into a partial termination of the interest rate swap and reduced the notional amount to $50.0 million. 

The  facilities  contain  customary  covenants,  which  include,  among  others,  limitations  or  restrictions  on  the  incurrence  of 
indebtedness, the incurrence of liens, entry into sales and leaseback transactions, mergers, transfers of all or substantially all assets, 
transactions with affiliates, and certain transactions limiting the ability of subsidiaries to pay dividends, in each case, subject to 
certain exceptions. The New Credit Facility includes requirements, to be tested quarterly, that the Company maintains (i)  a minimum 
ratio of Consolidated EBITDA to consolidated interest expense of 3.25 to 1.0, (the "Interest Coverage Ratio"), (ii) a maximum 
ratio of Consolidated total indebtedness to Consolidated EBITDA of 3.75 to 1.0 ("the Leverage Ratio"), and (iii) a maximum ratio 
of senior secured indebtedness to Consolidated EBITDA of 3.25 to 1.0 (the "Senior Secured Leverage Ratio"). For these ratios, 
Consolidated EBITDA and consolidated interest expense are calculated using the most recent four consecutive fiscal quarters in 
a manner defined in the New Credit Facility. At December 31, 2018, the Company was in compliance with these covenants and 
it expects to remain in compliance with all of its debt covenants over the next twelve months.

Risk Management

We are exposed to certain market risks which exist as part of our ongoing business operations, including changes in currency 
exchange rates, the dependence on key customers, price volatility for certain commodities, and changes in interest rates. We do 
not engage in speculative or leveraged transactions and do not hold or issue financial instruments for trading purposes.

Foreign Currency Exposure

We conduct business through our subsidiaries in many different countries and fluctuations in currency exchange rates could have 
a significant impact on the reported results of operations, which are presented in U.S. dollars. A significant and growing portion 
of our products are manufactured in lower-cost locations and sold in various countries. Cross-border transactions, both with external 
parties and intercompany relationships, could result in increased foreign exchange exposures. A weakening of foreign currencies 
relative to the U.S. dollar would adversely affect the U.S. dollar value of the Company’s foreign currency-denominated sales, but 
would be beneficial to the cost of materials, products, and services purchased overseas. A strengthening of foreign currencies 
relative to the U.S. dollar would positively affect the U.S. dollar value of the Company’s foreign currency-denominated sales, but 

42

would have a negative effect on the cost of materials, products, and services purchased overseas. Our foreign currency exposure 
is primarily driven by changes in the Chinese renminbi (yuan), the Malaysian ringgit, and the Philippine peso. Based on our current 
sales and manufacturing activity, a sustained 10% weakening of the U.S. dollar for a period of one year would reduce our operating 
results by approximately $16.7 million pre-tax. See Note 10. Hedging Transactions and Derivative Instruments to our Consolidated 
Financial Statements under Item 8, "Financial Statements and Supplementary Data" for information on the Company's hedges of 
foreign currency exchange rate risk.

Dependence on Key Customers; Concentration of Credit

The loss of any key customer and our inability to replace revenues provided by a key customer may have a material adverse effect 
on  our  business  and  financial  condition.  For  the  years  ended  December 31,  2018,  2017,  and  2016, Apple  Inc.  accounted  for 
approximately 19%, 19%, and 20% of our total revenues, respectively. For the years ended December 31, 2017 and 2016,  Samsung 
Electronics Co., Ltd. accounted for approximately 10% and 12% of our total revenues, respectively. No other customer accounted 
for more than 10% of total revenues during these periods. If a key customer fails to meet payment obligations, our operating results 
and financial condition could be adversely affected.

Commodity Pricing

We use a wide variety of raw materials, primarily metals, and semi-processed or finished components, which are generally available 
from a number of sources. While the required raw materials are generally available, commodity pricing for various precious metals, 
such  as  palladium,  gold,  brass,  stainless  steel,  and  copper,  fluctuates. As  a  result,  our  operating  results  are  exposed  to  such 
fluctuations. Although some cost increases may be recovered through increased prices to customers if commodity prices trend 
upward, we attempt to control such costs through fixed-price contracts with suppliers and various other programs, such as our 
global supply chain activities.

Interest Rates

Borrowings under our New Credit Facility are at variable interest rates. A hypothetical 100 basis point change in interest rates 
affecting our external variable rate borrowings as of December 31, 2018 would impact our operating results by $0.1 million on a 
pre-tax basis.

Critical Accounting Policies

Our Consolidated Financial Statements are based on the application of GAAP. GAAP requires the use of estimates, assumptions, 
judgments, and subjective interpretations of accounting principles that have an impact on the assets, liabilities, revenues, and 
expense amounts we report. These estimates can also affect supplemental information contained in our public disclosures, including 
information regarding contingencies, risk, and our financial condition. The significant accounting policies used in the preparation 
of our Consolidated Financial Statements are discussed in Note 1. Summary of Significant Accounting Policies to the Consolidated 
Financial Statements under Item 8, "Financial Statements and Supplementary Data." The accounting assumptions and estimates 
discussed in the section below are those that we consider most critical to an understanding of our financial statements because 
they inherently involve significant judgments and estimates. We believe our use of estimates and underlying accounting assumptions 
conforms to GAAP and is consistently applied. We review valuations based on estimates for reasonableness on a consistent basis.

Revenue Recognition: We adopted ASC 606, Revenue from Contracts with Customers, on January 1, 2018 using the modified 
retrospective (cumulative effect) transition method. Under this transition method, results for reporting periods beginning January 
1, 2018 or later are presented under ASC 606, while prior period results continue to be reported in accordance with previous 
guidance. We did not recognize a cumulative effect adjustment to retained earnings as of January 1, 2018 as the impact of the 
standard on the Consolidated Financial Statements was not material. As described below, the analysis of contracts under ASC 606 
supports the recognition of revenue at a point in time, resulting in revenue recognition timing that is materially consistent with 
our historical practice of recognizing revenue when title and risk of loss pass to the customer.

Revenue is recognized when control of the promised goods or services is transferred to the customer in an amount that reflects 
the consideration we expect to be entitled to in exchange for those goods or services. The majority of our revenue is generated 
through the manufacture and sale of a broad range of specialized products and components. For product and component sales, 
each good sold to a customer typically represents a distinct performance obligation. Our performance obligation to provide goods 
to a customer is typically satisfied at a point in time upon completion of the shipping process as indicated by the terms of the 
contract, at which point control is transferred to the customer and revenue is recognized. We have no significant arrangements 

43

with multiple performance obligations. Remaining performance obligations consist of the aggregate amount of the total transaction 
price that is unsatisfied or partially satisfied. As of December 31, 2018, our total remaining performance obligations are immaterial. 
We recognize sales-based royalty revenue under third-party license agreements as the related sales are made by licensees.

The terms of a contract or historical business practice can give rise to variable consideration, including customer discounts, rebates, 
and returns. We estimate variable consideration using either the expected value or most likely amount method. We include estimated 
amounts in the transaction price to the extent it is probable that a significant reversal of revenue will not occur in a subsequent 
reporting period. Our estimates of variable consideration are based on all reasonably available information (historical, current, 
and forecasted). Rebates are recognized over the contract period based on expected revenue levels. Sales discounts and rebates 
totaled $8.1 million, $9.1 million, and $8.7 million for the years ended December 31, 2018, 2017, and 2016, respectively. Returns 
and allowances totaled $7.7 million, $8.5 million, and $5.1 million for the years ended December 31, 2018, 2017, and 2016, 
respectively.

Inventories: Inventories are stated at the lower of cost or net realizable value, determined on the first-in, first-out ("FIFO") basis. 
The value of inventory may decline as a result of surplus inventory, price reductions, or technological obsolescence. It is the 
Company’s policy to carry reserves against the carrying value of inventory when items have no future demand (obsolete inventory) 
and additionally, where inventory items on hand have demand, yet have insufficient forecasted activity to consume the entire stock 
within a reasonable period. It is the Company’s policy to carry reserves against the carrying value of such at-risk inventory items 
after considering the nature of the risk and any mitigating factors.

Goodwill and Indefinite-Lived Intangible Assets: Goodwill represents the excess of purchase consideration over the fair value of 
the net assets of businesses acquired. Goodwill and certain other intangible assets deemed to have indefinite lives (primarily 
trademarks) are not amortized. Instead, goodwill and indefinite-lived intangible assets are tested for impairment at least annually, 
or more frequently if there are events or circumstances indicating the carrying value of individual reporting units or assets may 
exceed their respective fair values on a more likely than not basis. The Company performs its annual impairment assessment in 
the fourth quarter of each year on October 1. Recoverability of goodwill is measured at the reporting unit level. Following the sale 
of the Timing Device Business on November 28, 2017, the Company has three reporting units. The goodwill balances associated 
with the Mobile Consumer Electronics ("MCE"), Hearing Health Technologies ("HHT"), and Capacitors reporting units were 
$722.1 million, $137.8 million, and $28.0 million, respectively, as of December 31, 2018.

The impairment assessment compares the fair value of each reporting unit to its carrying value. Impairment is measured as the 
amount by which the carrying value of a reporting unit exceeds its fair value. Fair value is estimated using a discounted cash flow 
approach  that  includes  the  Company’s  market  participant  assumptions,  projections  of  future  cash  flows  based  on  historical 
performance and future estimated results, determinations of appropriate discount rates, and other assumptions which are considered 
reasonable and inherent in the discounted cash flow analysis. Significant assumptions used in the assessment include forecasted 
revenue and terminal growth rates, profit margins, income taxes, and the Company's weighted average cost of capital. These 
assumptions  require  significant  judgment  and  actual  results  may  differ  from  estimated  amounts. The  fair  value  of  all  of  the 
Company’s reporting units exceeded the carrying values by at least 50%, resulting in no goodwill impairment charges. Potential 
circumstances that could have a negative effect on the fair value of our reporting units include, but are not limited to, lower than 
forecasted growth rates or profit margins and changes in the weighted average cost of capital. A reduction in the estimated fair 
value of the reporting units could trigger an impairment in the future. The Company cannot predict the occurrence of certain events 
or changes in circumstances that might adversely affect the carrying value of goodwill and intangible assets. 

In testing its other indefinite-lived intangible assets for impairment, the Company uses a relief from royalty method to calculate 
and compare the fair value of the intangible asset to its carrying value. This method estimates the fair value of trademarks by 
calculating the present value of royalty income that could hypothetically be earned by licensing the trademark to a third party. Any 
excess of carrying value over the estimated fair value is recognized as an impairment loss. No impairment of indefinite-lived 
intangibles was indicated for the years ended December 31, 2018, 2017, or 2016.

See Note 7. Goodwill and Other Intangible Assets to our Consolidated Financial Statements under Item 8, "Financial Statements 
and Supplementary Data" for additional information on goodwill and indefinite-lived intangible assets.

44

 
Other Intangible and Long-Lived Assets: Other intangible assets with determinable lives consist primarily of customer relationships, 
unpatented technology, patents, and trademarks and are amortized over their estimated useful lives, historically ranging from 5 to 
15 years. We rely on patents and proprietary technology, and seek patent protection for products and production methods. We 
capitalize external legal costs incurred in the defense of our patents when we believe that a significant, discernible increase in 
value will result from the defense and a successful outcome of the legal action is probable. These costs are amortized over the 
remaining  estimated  useful  life  of  the  patent,  which  is  typically  7  to  10  years. We  assess  future  economic  benefit  and/or  the 
successful outcome of legal action related to patent defense, which involves considerable management judgment and a different 
outcome could result in material write-offs of the carrying value of these assets. We capitalized no legal costs related to the defense 
of our patents during the years ended December 31, 2018, 2017, and 2016.

Long-lived assets (including intangible assets with determinable lives) are reviewed for impairment whenever events or changes 
in circumstances indicate that the carrying amount of an asset may not be recoverable. If an indicator of impairment exists for any 
grouping of assets, an estimate of undiscounted future cash flows is produced and compared to its carrying value. If an asset is 
determined to be impaired, the loss is measured by the excess of the carrying amount of the asset over its fair value as determined 
by an estimate of discounted future cash flows.

We recorded no impairments during the year ended December 31, 2018. During the years ended December 31, 2017 and 2016, 
we recorded impairments and other charges related to continuing operations of $21.3 million and $0.5 million, respectively. During 
the year ended December 31, 2017, we recorded pre-tax impairment charges of $5.1 million related to fixed assets and $16.2 
million related to intangible assets resulting from an updated strategic plan that was completed for Audio segment product lines. 
The updated strategic plan identified a decline of future demand for a specific product line, which indicated projected future cash 
flows  may  not  be  sufficient  to  recover  the  carrying  value  of  the  associated  unpatented  technologies  and  property,  plant,  and 
equipment assets. See Note 4. Impairments to our Consolidated Financial Statements under Item 8, "Financial Statements and 
Supplementary Data" for additional details.

Income Taxes and Deferred Tax Balances: We record a provision for income taxes for the anticipated tax consequences of the 
reported results of operations using the asset and liability method. Under this method, we recognize deferred tax assets and liabilities 
for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and 
liabilities, as well as for operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using the tax 
rates that are expected to apply to taxable income for the years in which those tax assets and liabilities are expected to be realized 
or settled. A valuation allowance is recorded to reduce deferred tax assets to the net amount that is more likely than not to be 
realized.

We establish valuation allowances for our deferred tax assets if, based on all available positive and negative evidence, it is more 
likely than not that some portion or all of the deferred tax assets will not be realized. In making such assessments, significant 
weight  is  given  to  evidence  that  can  be  objectively  verified.  The  assessment  of  the  need  for  a  valuation  allowance  requires 
considerable judgment on the part of management with respect to the benefits that could be realized from future taxable income, 
as well as other positive and negative factors.

We have evaluated our deferred tax assets for each of the reporting periods, including an assessment of cumulative income over 
the prior three-year period. Since we are in a cumulative loss position in the U.S., there is significant negative evidence that impairs 
the ability to rely on projections of future income. Due to a lack of significant positive evidence and cumulative losses in the 
respective  prior  three-year  periods,  a  valuation  allowance  was  required  for  the  2018,  2017,  and  2016  periods. The  valuation 
allowance was reduced in 2017 as a result of income recognized under the Internal Revenue Code Section 965 tax on foreign 
deferred earnings and changes to the net operating loss carryforward periods, allowing the use of existing deferred tax liabilities 
to reduce existing valuation allowances.

We recognize tax benefits from uncertain tax positions only if we believe that 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. Adjustments are made to these 
reserves when facts and circumstances change, such as the closing of a tax audit or the refinement of an estimate. To the extent 
that the final tax outcome of these matters is different than the amounts recorded, such differences will affect the provision for 
income taxes in the period in which such determination is made and could have a material impact on our financial condition and 
operating results. The provision for income taxes includes the effects of any reserves that are believed to be appropriate, as well 
as the related net interest and penalties. The effective tax rates on a continuing operations basis for 2018, 2017, and 2016 were a  
7.4% benefit, 66.5% provision, and 29.5% provision, respectively.

45

On December 22, 2017, the Tax Reform Act was enacted, which significantly changed U.S. tax law by, among other things, lowering 
corporate income tax rates, implementing a territorial tax system, and imposing a repatriation tax on deemed repatriated earnings 
of foreign subsidiaries. The Tax Reform Act permanently reduces the U.S. corporate income tax rate from a maximum of 35% to 
a flat 21% rate, effective January 1, 2018. The Tax Reform Act also provided for a one-time deemed repatriation of post-1986 
undistributed foreign subsidiary E&P through the year ended December 31, 2017. The Global Intangible Low-Taxed Income 
("GILTI") provisions of the Tax Reform Act also require us to include in our U.S. income tax return foreign subsidiary earnings 
in excess of an allowable return on the foreign subsidiary’s tangible assets. We were subject to the GILTI provisions beginning in 
2018. As we have elected to account for GILTI tax in the period in which it is incurred, we did not provide any deferred tax impacts 
of GILTI in our Consolidated Financial Statements under Item 8, "Financial Statements and Supplementary Data."

On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of U.S. 
GAAP  in  situations  when  a  registrant  does  not  have  the  necessary  information  available,  prepared,  or  analyzed  (including 
computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Reform Act. We recognized  
provisional tax impacts related to deemed repatriated earnings, the change in beginning of year valuation allowance, and the benefit 
for the remeasurement of deferred tax assets and liabilities as of December 31, 2017. During the fourth quarter of 2018, we finalized 
our accounting for the effects of the Tax Reform Act under SAB 118. We recorded a $17.8 million reduction to the transition tax 
liability due to the impact of an IRS approval for an entity classification received during the fourth quarter of 2018.  These amounts 
are included in our Consolidated Financial Statements under Item 8, "Financial Statements and Supplementary Data."

Although our accounting for the effects of the Tax Reform Act is finalized under SAB 118, there may be future adjustments based 
on potential changes in the interpretation of the Tax Reform Act, its supporting regulations, and subsequent guidance that may be 
issued. The impact of any such adjustments, which could have a material impact on the Consolidated Financial Statements, will 
be recognized in the period the changes arise or the related regulations are enacted. We are in the process of evaluating the final 
regulations on Section 965, which were released by the IRS on January 15, 2019, and will recognize any related impact in the first 
quarter of 2019.

Accruals and Reserves: We have accruals and reserves that require the use of estimates and judgment with regard to risk exposure 
and ultimate liability. We estimate losses under these programs using certain factors, which include but are not limited to, actuarial 
assumptions, our experience, and relevant industry data. We review these factors quarterly and consider the current level of accruals 
and  reserves  adequate  relative  to  current  market  conditions  and  experience.  We  have  established  liabilities  for  restructuring 
activities, in accordance with appropriate accounting principles. These liabilities, for both severance and exit costs, require the use 
of estimates. Though we believe that these estimates accurately reflect the anticipated costs, actual results may be different than 
the estimated amounts.

Stock-Based Compensation: The principal awards issued under the stock-based compensation plans include stock options, restricted 
stock units ("RSUs"), and performance share units ("PSUs"). The cost for such awards is measured at the grant date based on the 
fair value of the award. The value of the portion of the award that is expected to ultimately vest is generally recognized as expense 
on a straight-line basis, generally over the explicit service period and is included in Cost of goods sold, Research and development 
expenses, and Selling and administrative expenses in the Consolidated Statements of Earnings, depending on the functional area 
of the underlying employees. The cost related to PSUs is recognized based on the expected attainment of performance targets. 
Changes  in  estimates  that  impact  the  number  of  shares  expected  to  vest  are  recognized  prospectively  through  cumulative 
adjustments.

We use the Black-Scholes valuation model to estimate the fair value of stock options granted to employees. The fair value of each 
RSU granted is equal to the share price at the date of the grant. The fair value of PSUs is determined by using a binomial model 
simulation. At the time of grant, we estimate forfeitures, based on historical experience, in order to estimate the portion of the 
award that will ultimately vest. See Note 13. Equity Incentive Program to our Consolidated Financial Statements under Item 8, 
"Financial Statements and Supplementary Data" for additional information related to our stock-based compensation.

Report of Independent Registered Public Accounting Firm 

To the Board of Directors and Stockholders of Knowles Corporation:

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Knowles Corporation and its subsidiaries (the “Company”) as 
of December 31, 2018 and 2017, and the related consolidated statements of earnings, comprehensive earnings, stockholders’ equity 
and cash flows for each of the three years in the period ended December 31, 2018, including the related notes and schedule of 
valuation and qualifying accounts for each of the three years in the period ending December 31, 2018 (collectively referred to as 
the  “consolidated  financial  statements”).  We  also  have  audited  the  Company's  internal  control  over  financial  reporting  as  of 
December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of 
Sponsoring Organizations of the Treadway Commission (COSO).  

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position 
of the Company as of December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the three years 
in the period ended December 31, 2018 in conformity with accounting principles generally accepted in the United States of America. 
Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of 
December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control 
over  financial  reporting,  and  for  its  assessment  of  the  effectiveness  of  internal  control  over  financial  reporting,  included  in 
Management's Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express 
opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based 
on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) 
(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 
audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether 
due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.  

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement 
of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such 
procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial 
statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as 
well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial 
reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness 
exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits 
also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide 
a reasonable basis for our opinions.

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 (i) pertain 
to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets 
of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial 
statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are 
being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable 
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that 
could have a material effect on the financial statements.

49

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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies

Background  -  Knowles  Corporation  (NYSE:KN)  is  a  market  leader  and  global  provider  of  advanced  micro-acoustic,  audio 
processing, and precision device solutions, serving the mobile consumer electronics, communications, medical, defense, aerospace, 
and industrial markets. The Company uses its leading position in micro-electro-mechanical systems ("MEMS") microphones and 
strong capabilities in audio processing technologies to optimize audio systems and improve the user experience in mobile, ear, 
and Internet of Things ("IoT") applications. Knowles is also the leader in acoustics components used in hearing aids and has a 
strong position in high-end capacitors. The Company's focus on its customers, combined with its unique technology, proprietary 
manufacturing techniques, rigorous testing, and global scale, enable the Company to deliver innovative solutions that optimize 
the  user  experience.  References  to  "Knowles,"  "the  Company,"  "we,"  "our,"  and  "us"  refer  to  Knowles  Corporation  and  its 
consolidated subsidiaries. Our common stock began trading under the ticker symbol “KN” on the New York Stock Exchange (the 
“NYSE”) on March 3, 2014.

On January 19, 2018, the Company acquired substantially all of the assets of Compex Corporation ("Compex"), a capacitors 
manufacturer. See Note 3. Acquisitions for additional information related to the transaction.

On November 28, 2017, the Company completed the sale of its high-end oscillators business ("Timing Device Business"). On July 
7, 2016, the Company completed the sale of its speaker and receiver product line (“Speaker and Receiver Product Line”). In 
accordance  with  Accounting  Standards  Codification  ("ASC")  205-20,  Presentation  of  Financial  Statements  -  Discontinued 
Operations, the results of operations and related assets and liabilities for the Timing Device Business and Speaker and Receiver 
Product Line have been reclassified as discontinued operations for all periods presented. See Note 2. Disposed and Discontinued 
Operations for additional information related to the transactions.

In January 2017, the Company changed its allocation of resources and internal reporting structure to facilitate delivering growth 
in its core business. Following these changes, the Company's two reportable segments are Audio and Precision Devices ("PD"). 
See Note 17. Segment Information for additional information related to the Company’s segments.

Financial Statement Presentation - The Consolidated Financial Statements included in this Annual Report on Form 10-K are 
presented in conformity with U.S. generally accepted accounting principles ("U.S. GAAP"). 

Use of Estimates - The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates 
and assumptions that affect the amounts reported in the accompanying financial statements and disclosures. These estimates may 
be adjusted due to changes in future economic, industry, or customer financial conditions, as well as changes in technology or 
demand. Estimates are used in accounting for, among other items, allowances for doubtful accounts receivable, inventory reserves, 
restructuring reserves, warranty reserves, pension and post-retirement plans, stock-based compensation, corporate allocations, 
useful lives for depreciation and amortization of long-lived assets, future cash flows associated with impairment testing for goodwill, 
indefinite-lived intangible assets and other long-lived assets, deferred tax assets, uncertain income tax positions, changes in tax 
laws, and contingencies. Actual results may ultimately differ from estimates, although management does not believe such differences 
would materially affect the financial statements in any individual year. Estimates and assumptions are periodically reviewed and 
the effects of revisions are reflected in the Consolidated Financial Statements in the period that they are determined.

Cash and Cash Equivalents - Cash and cash equivalents include cash on hand, demand deposits, and temporary cash investments 
with original maturities less than three months.

Allowance for Doubtful Accounts – The Company maintains allowances for estimated losses as a result of customers' inability 
to make required payments. Management evaluates the aging of the accounts receivable balances, the financial condition of its 
customers, historical trends, and the time outstanding of specific balances to estimate the amount of accounts receivable that may 
not be collected in the future and records the appropriate provision.

Inventories – Inventories are stated at the lower of cost or net realizable value, determined on the first-in, first-out ("FIFO") basis. 
The value of inventory may decline as a result of surplus inventory, price reductions, or technological obsolescence. It is the 
Company’s policy to carry reserves against the carrying value of inventory when items have no future demand (obsolete inventory) 
and additionally, where inventory items on hand have demand, yet have insufficient forecasted activity to consume the entire stock 
within a reasonable period. It is the Company’s policy to carry reserves against the carrying value of such at-risk inventory items 
after considering the nature of the risk and any mitigating factors.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Prepaid and Other Current Assets – Prepaid and other current assets at December 31, 2017 includes $10.0 million held in escrow 
related to the sale of the Timing Device Business that was received during the third quarter of 2018. The remaining balance at 
December 31, 2018 and 2017 is made up of prepaid insurance, supplier prepayments, prepaid licensing fees, and other miscellaneous 
prepaid assets, none of which are individually significant.

Property, Plant, and Equipment - Property, plant, and equipment includes the historic cost of land, buildings, equipment, and 
significant improvements to existing plant and equipment or, in the case of acquisitions, a fair market value appraisal of such assets 
completed at the time of acquisition. Property, plant, and equipment also includes the cost of purchased software. Expenditures 
for maintenance, repairs, and minor renewals are expensed as incurred. When property or equipment is sold or otherwise disposed 
of, the related cost and accumulated depreciation is removed from the respective accounts, and the gain or loss realized on disposition 
is reflected in earnings. The Company historically depreciates its assets on a straight-line basis over their estimated useful lives 
as follows: buildings and improvements 5 to 31.5 years; machinery and equipment 1.5 to 7 years; furniture and fixtures 2 to 5
years; vehicles 3 to 5 years; and software 3 to 5 years. 

Derivative Instruments - The Company uses derivative financial instruments to hedge its exposures to various risks, including 
interest  rate  and  foreign  currency  exchange  rate  risk. The  Company  does  not  enter  into  derivative  financial  instruments  for 
speculative purposes and does not have a material portfolio of derivative financial instruments. Derivative financial instruments 
used for hedging purposes must be designated and effective as a hedge of the identified risk exposure at inception of the contract. 
The Company recognizes all derivatives as either assets or liabilities on the Consolidated Balance Sheets and measures those 
instruments at fair value. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the 
derivatives is recorded as a component of other comprehensive earnings and subsequently recognized in net earnings when the 
hedged items impact earnings.

Goodwill and Indefinite-Lived Intangible Assets - Goodwill represents the excess of purchase consideration over the fair value 
of the net assets of businesses acquired. Goodwill and certain other intangible assets deemed to have indefinite lives (primarily 
trademarks) are not amortized. Instead, goodwill and indefinite-lived intangible assets are tested for impairment at least annually, 
or more frequently if there are events or circumstances indicating the carrying value of individual reporting units or assets may 
exceed their respective fair values on a more likely than not basis. The Company performs its annual impairment assessment in 
the fourth quarter of each year on October 1. Recoverability of goodwill is measured at the reporting unit level. Following the sale 
of the Timing Device Business on November 28, 2017, the Company has three reporting units. The goodwill balances associated 
with the Mobile Consumer Electronics ("MCE"), Hearing Health Technologies ("HHT"), and Capacitors reporting units were 
$722.1 million, $137.8 million, and $28.0 million, respectively, as of December 31, 2018.

The impairment assessment compares the fair value of each reporting unit to its carrying value. Impairment is measured as the 
amount by which the carrying value of a reporting unit exceeds its fair value. Fair value is estimated using a discounted cash flow 
approach  that  includes  the  Company’s  market  participant  assumptions,  projections  of  future  cash  flows  based  on  historical 
performance and future estimated results, determinations of appropriate discount rates, and other assumptions which are considered 
reasonable and inherent in the discounted cash flow analysis. Significant assumptions used in the assessment include forecasted 
revenue and terminal growth rates, profit margins, income taxes, and the Company's weighted average cost of capital. These 
assumptions  require  significant  judgment  and  actual  results  may  differ  from  estimated  amounts. The  fair  value  of  all  of  the 
Company’s reporting units exceeded the carrying values by at least 50%, resulting in no goodwill impairment charges. Potential 
circumstances that could have a negative effect on the fair value of our reporting units include, but are not limited to, lower than 
forecasted growth rates or profit margins and changes in the weighted average cost of capital. A reduction in the estimated fair 
value of the reporting units could trigger an impairment in the future. The Company cannot predict the occurrence of certain events 
or changes in circumstances that might adversely affect the carrying value of goodwill and intangible assets. 

In testing its other indefinite-lived intangible assets for impairment, the Company uses a relief from royalty method to calculate 
and compare the fair value of the intangible asset to its carrying value. This method estimates the fair value of trademarks by 
calculating the present value of royalty income that could hypothetically be earned by licensing the trademark to a third party. Any 
excess of carrying value over the estimated fair value is recognized as an impairment loss. No impairment of indefinite-lived 
intangibles was indicated for the years ended December 31, 2018, 2017, or 2016.

See Note 7. Goodwill and Other Intangible Assets for additional information on goodwill and indefinite-lived intangible assets.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Other  Intangible  and  Long-Lived  Assets  -  Other  intangible  assets  with  determinable  lives  consist  primarily  of  customer 
relationships, unpatented technology, patents, and trademarks and are amortized over their estimated useful lives, historically 
ranging from 5 to 15 years. The Company relies on patents and proprietary technology, and seeks patent protection for products 
and production methods. The Company capitalizes external legal costs incurred in the defense of its patents when it believes that 
a significant, discernible increase in value will result from the defense and a successful outcome of the legal action is probable. 
These costs are amortized over the remaining estimated useful life of the patent, which is typically 7 to 10 years. The Company’s 
assessment of future economic benefit and/or the successful outcome of legal action related to patent defense involves considerable 
management judgment and a different outcome could result in material write-offs of the carrying value of these assets. The Company 
capitalized no legal costs related to the defense of its patents during the years ended December 31, 2018, 2017, and 2016.

Long-lived assets (including intangible assets with determinable lives) are reviewed for impairment whenever events or changes 
in circumstances indicate that the carrying amount of an asset may not be recoverable. If an indicator of impairment exists for any 
grouping of assets, an estimate of undiscounted future cash flows is produced and compared to its carrying value. If an asset is 
determined to be impaired, the loss is measured by the excess of the carrying amount of the asset over its fair value as determined 
by an estimate of discounted future cash flows.

The Company recorded no impairments during the year ended December 31, 2018. During the years ended December 31, 2017
and 2016, the Company recorded impairments and other charges related to its continuing operations of $21.3 million and $0.5 
million, respectively. See Note 4. Impairments for additional details.

Foreign Currency - Assets and liabilities of non-U.S. subsidiaries, where the functional currency is not the U.S. dollar, are translated 
into U.S. dollars at year-end exchange rates. Revenue and expense items are translated using weighted-average yearly exchange 
rates. Foreign currency translation gains and losses are included as a component of Accumulated other comprehensive loss. Assets 
and liabilities of an entity that are denominated in currencies other than an entity’s functional currency are re-measured into the 
functional currency using end of period exchange rates or historical rates where applicable to certain balances. Gains and losses 
related to these re-measurements are recorded within the Consolidated Statements of Earnings as a component of Other expense 
(income), net.

Revenue Recognition - The Company adopted ASC 606, Revenue from Contracts with Customers, on January 1, 2018 using the 
modified retrospective (cumulative effect) transition method. Refer to the Recently Adopted Accounting Standards section below 
for additional information.

Stock-Based  Compensation  – The  principal  awards  issued  under  the  stock-based  compensation  plans  include  stock  options, 
restricted stock units ("RSUs"), and performance share units ("PSUs"). The cost for such awards is measured at the grant date 
based on the fair value of the award. The value of the portion of the award that is expected to ultimately vest is generally recognized 
as expense on a straight-line basis, generally over the explicit service period and is included in Cost of goods sold, Research and 
development expenses, and Selling and administrative expenses in the Consolidated Statements of Earnings, depending on the 
functional area of the underlying employees. The cost related to PSUs is recognized based on the expected attainment of performance 
targets. Changes in estimates that impact the number of shares expected to vest are recognized prospectively through cumulative 
adjustments.

The Company uses the Black-Scholes valuation model to estimate the fair value of stock options granted to employees. The fair 
value of each RSU granted is equal to the share price at the date of the grant. The fair value of each PSU is determined using a 
binomial model simulation. At the time of grant, the Company estimates forfeitures, based on historical experience, in order to 
estimate the portion of the award that will ultimately vest. See Note 13. Equity Incentive Program for additional information related 
to the Company’s stock-based compensation.

Income Taxes - The Company records a provision for income taxes for the anticipated tax consequences of the reported results 
of operations using the asset and liability method. Under this method, the Company recognizes deferred tax assets and liabilities 
for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and 
liabilities, as well as for operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using the tax 
rates that are expected to apply to taxable income for the years in which those tax assets and liabilities are expected to be realized 
or settled. The Company offsets and presents deferred tax liabilities and assets, as well as any related valuation allowance, as a 
single non-current amount on the Consolidated Balance Sheets on a jurisdictional basis.

58

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company establishes valuation allowances for its deferred tax assets if, based on all available positive and negative evidence, 
it is more likely than not that some portion or all of the deferred tax assets will not be realized. In making such assessments, 
significant weight is given to evidence that can be objectively verified. The assessment of the need for a valuation allowance 
requires considerable judgment on the part of management with respect to the benefits that could be realized from future taxable 
income, as well as other positive and negative factors. Management considers the scheduled reversal of deferred tax liabilities, 
projected future taxable income, and tax-planning strategies in making this assessment.

The Company recognizes tax benefits from uncertain tax positions only if it believes that 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. Adjustments are 
made to these reserves when facts and circumstances change, such as the closing of a tax audit or the refinement of an estimate. 
To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will affect the 
provision for income taxes in the period in which such determination is made and could have a material impact on the Company's 
financial condition and operating results. The provision for income taxes includes the effects of any reserves that are believed to 
be appropriate, as well as the related net interest and penalties.

On December 22, 2017, the U.S. bill commonly referred to as the Tax Cuts and Jobs Act ("Tax Reform Act") was enacted, which 
significantly changed U.S. tax law by, among other things, lowering corporate income tax rates, implementing a territorial tax 
system, and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. The Tax Reform Act permanently 
reduces the U.S. corporate income tax rate from a maximum of 35% to a flat 21% rate, effective January 1, 2018. The Tax Reform 
Act also provided for a one-time deemed repatriation of post-1986 undistributed foreign subsidiary earnings and profits ("E&P") 
through the year ended December 31, 2017. The Global Intangible Low-Taxed Income ("GILTI") provisions of the Tax Reform 
Act also require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return 
on the foreign subsidiary’s tangible assets. The Company was subject to the GILTI provisions beginning in 2018. The Company 
has elected to account for GILTI tax in the period in which it is incurred, and therefore has not provided any deferred tax impacts 
of GILTI in its Consolidated Financial Statements.

On December 22, 2017, the Securities and Exchange Commission ("SEC") staff issued Staff Accounting Bulletin No. 118 (“SAB 
118”) to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, 
prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of 
the Tax  Reform Act. The Company  recognized provisional tax impacts related to  deemed repatriated earnings, the change  in 
beginning of year valuation allowance, and the benefit for the remeasurement of deferred tax assets and liabilities as of December 
31, 2017. During the fourth quarter of 2018, the Company finalized its accounting for the effects of the Tax Reform Act under 
SAB 118. The Company recorded a $17.8 million reduction to the net transition tax liability due to the impact of an Internal 
Revenue Service ("IRS") approval for an entity classification received during the fourth quarter of 2018.

During the third quarter of 2018, the Company recorded an uncertain tax position of $36.0 million related to consequences of the 
Tax Reform Act. As a result of the IRS approval for an entity classification received during the fourth quarter of 2018, the Company 
recognized a $36.0 million benefit related to the release of the uncertain tax position.

Although  the  Company’s  accounting  for  the  effects  of  the Tax  Reform Act  is  finalized  under  SAB  118,  there  may  be  future 
adjustments based on potential changes in the interpretation of the Tax Reform Act, its supporting regulations, and subsequent 
guidance that may be issued. The impact of any such adjustments, which could have a material impact on the Consolidated Financial 
Statements, will be recognized in the period the changes arise or the related regulations are enacted. The Company is in the process 
of evaluating the final regulations on Section 965, which were released by the IRS on January 15, 2019, and will recognize any 
related impact in the first quarter of 2019.

Research and Development Costs – Research and development costs, including qualifying engineering costs, are expensed when 
incurred.

Non-cash Investing Activities - Purchases of property, plant, and equipment included in accounts payable at December 31, 2018, 
2017, and 2016 were $7.1 million, $8.5 million, and $1.5 million, respectively. These non-cash amounts are not reflected as outflows 
to Additions to property, plant, and equipment within investing activities of the Consolidated Statements of Cash Flows for the 
respective periods.

Reclassifications - Certain amounts in prior years have been reclassified to conform to the current year presentation. Refer to the 
Recently Adopted Accounting Standards section below for additional information.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Recently Issued Accounting Standards 

In August 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2018-14 to 
amend disclosure requirements related to defined benefit pension and other postretirement plans. The standard is effective for 
public business entities for fiscal years beginning after December 15, 2020. Early adoption is permitted and retrospective application 
of the guidance is required. The Company has not yet determined the impact of the standard on its disclosures or its adoption date.

In February 2018, the FASB issued ASU 2018-02, which allows the reclassification from accumulated other comprehensive income 
to retained earnings of stranded tax effects resulting from the Tax Reform Act. The standard also requires certain disclosures 
concerning stranded tax effects regardless of the election with respect to stranded tax effects resulting from the Tax Reform Act. 
The standard is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal 
years. The standard should be applied either in the period of adoption or retrospectively to each period (or periods) in which the 
effects of the Tax Reform Act were recognized. The Company has elected to reclassify the stranded tax effects resulting from the 
Tax Reform Act upon adoption of the standard on January 1, 2019, the impact of which will not be significant.

In February 2016, the FASB issued ASU 2016-02 and issued subsequent amendments to the initial guidance within ASU 2018-01, 
ASU 2018-10, ASU 2018-11, and ASU 2018-20, which are collectively referred to as "ASC 842." This guidance requires a lessee 
to recognize a lease liability and right-of-use asset for all leases, including operating leases, with a term greater than 12 months. 
The guidance also provides clarification surrounding the presentation of the effects of leases in the statement of earnings. This 
standard is effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within 
those fiscal years. Prior to the issuance of ASU 2018-11 in July 2018, the standard required a modified retrospective transition 
method under which the guidance would be applied at the beginning of the earliest comparative period presented in the financial 
statements. ASU 2018-11 allows entities to elect an additional transition method under which the guidance would be applied as 
of the adoption date. The Company will adopt the standard under this new transition method that will not require comparative 
period financial statements to be recast.

The standard includes a number of optional practical expedients that entities may elect to apply. The Company will elect the 
transition package of practical expedients for leases that commenced before the adoption date, which among other things, allows 
the Company to carry forward historical lease classifications. The Company will also elect the practical expedient to not separate 
nonlease components from lease components, which may increase lease liabilities and right-of-use assets through the inclusion of 
payments for nonlease components such as maintenance.

The  Company  is  finalizing  its  evaluation  of  the  impact  of  the  standard  on  its  Consolidated  Financial  Statements,  accounting 
processes, internal controls, and disclosures. The impact of adoption will depend on the lease portfolio as of the transition date 
and the Company's accounting policy elections. The Company expects to recognize $40 million to $45 million of operating lease 
liabilities and $37 million to $42 million of operating lease right-of-use assets on its Consolidated Balance Sheets upon adoption 
of the standard. The standard is not expected to have any other material impacts on the Consolidated Financial Statements. The 
adoption date for the standard is January 1, 2019.

Recently Adopted Accounting Standards

In August 2017, the FASB issued ASU 2017-12 with the objective of improving the financial reporting of hedging relationships 
to better portray the economic results of an entity’s risk management activities in its financial statements and simplify the application 
of hedge accounting guidance. The standard is effective for public business entities for fiscal years beginning after December 15, 
2018, and interim periods within those fiscal years. The standard requires adoption on a modified retrospective basis for hedging 
relationships existing as of the adoption date and on a prospective basis for the amended presentation and disclosure requirements. 
The Company elected to early adopt the standard as of January 1, 2018. Adoption of the standard did not result in a cumulative 
effect adjustment to retained earnings as of January 1, 2018 as the Company had no cumulative ineffectiveness recognized under 
its hedging relationships existing as of the adoption date. See Note 10. Hedging Transactions and Derivative Instruments for detail 
on the Company's prospective adoption of the amended presentation and disclosure requirements. The adoption of this standard 
had no other impact on the Consolidated Financial Statements.

60

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

In May 2017, the FASB issued ASU 2017-09 that provides guidance about when a change to the terms or conditions of a share 
based payment award must be accounted for as a modification. The new guidance requires modification accounting if the fair 
value, vesting condition, or classification of an award is not the same immediately before and after a change to the terms and 
conditions of the award. This standard is effective for public business entities for fiscal years beginning after December 15, 2017, 
and interim periods within those fiscal years. The Company prospectively adopted this guidance on January 1, 2018, which had 
no impact on the Consolidated Financial Statements.

In March 2017, the FASB issued ASU 2017-07 primarily to improve the presentation of net periodic pension and post-retirement 
benefit cost. The new guidance requires that an employer report the service cost component in the same line item or items as other 
compensation costs arising from services rendered by the pertinent employees during the period. The other components of net 
benefit cost are required to be presented in the statement of earnings separately from the service cost component and outside of 
any subtotal of operating income. This standard is effective for public business entities for fiscal years beginning after December 
15, 2017, and interim periods within those fiscal years. The Company adopted this guidance on January 1, 2018 using a retrospective 
approach for the presentation of net benefit cost components. For the year ended December 31, 2017, net benefit income other 
than service cost of $0.3 million previously presented in both the Cost of goods sold and Selling and administrative expenses lines 
on the Consolidated Statements of Earnings has been reclassified to the Other expense (income), net line. For the year ended 
December 31, 2016, net benefit income other than service cost of $0.2 million previously presented in the Cost of goods sold line 
on the Consolidated Statements of Earnings has been reclassified to the Other expense (income), net line. The adoption of this 
standard had no other impact on the Consolidated Financial Statements. See Note 15. Employee Benefit Plans for additional 
information related to the Company’s pension and post-retirement plans.

In January 2017, the FASB issued ASU 2017-01, which requires a reporting entity to clarify the definition of a business with the 
objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or 
disposals) of assets or liabilities. This standard is effective for public business entities for annual periods beginning after December 
15, 2017, including interim periods within those periods. The Company prospectively adopted this guidance on January 1, 2018, 
which had no impact on the Consolidated Financial Statements.

In August 2016, the FASB issued ASU 2016-15 with the objective of reducing the existing diversity in practice in how certain 
cash receipts and cash payments are presented and classified in the statement of cash flows. The new guidance requires evaluation 
of cash receipts and payments on the basis of the nature of the underlying cash flows and provides clarity for categorization for 
specific transactions. This standard is effective for public business entities for fiscal years beginning after December 15, 2017, 
and interim periods within those fiscal years. The Company retrospectively adopted this guidance on January 1, 2018, which had 
no impact on the Consolidated Financial Statements.

In January 2016, the FASB issued ASU 2016-01, which requires a company to present separately in other comprehensive income 
the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk if the 
entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. This 
standard is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within 
those fiscal years. The Company adopted this guidance on a modified retrospective basis as of January 1, 2018, which had no 
impact on the Consolidated Financial Statements.

In May 2014, the FASB issued ASU 2014-09 and issued subsequent amendments to the initial guidance within ASU 2015-14, 
ASU 2016-08, ASU 2016-10, ASU 2016-12, and ASU 2016-20, which are collectively referred to as "ASC 606." The core principal 
of the guidance is to provide a comprehensive revenue recognition model that requires a company to recognize revenue to depict 
the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for 
those goods or services. The guidance also requires additional disclosure about the nature, amount, timing, and uncertainty of 
revenue and cash flows arising from customer contracts. The standard is effective for annual and interim periods beginning after 
December 15, 2017.

On January 1, 2018, the Company adopted ASC 606 using the modified retrospective (cumulative effect) transition method. Under 
this transition method, results for reporting periods beginning January 1, 2018 or later are presented under ASC 606, while prior 
period results continue to be reported in accordance with previous guidance. The Company did not recognize a cumulative effect 
adjustment to retained earnings as of January 1, 2018 as the impact of the standard on the Consolidated Financial Statements was 
not material. As described below, the analysis of contracts under ASC 606 supports the recognition of revenue at a point in time, 
resulting in revenue recognition timing that is materially consistent with our historical practice of recognizing revenue when title 
and risk of loss pass to the customer.

61

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Revenue is recognized when control of the promised goods or services is transferred to the customer in an amount that reflects 
the consideration the Company expects to be entitled to in exchange for those goods or services. The majority of the Company’s 
revenue is generated through the manufacture and sale of a broad range of specialized products and components. For product and 
component sales, each good sold to a customer typically represents a distinct performance obligation. The Company’s performance 
obligation to provide goods to a customer is typically satisfied at a point in time upon completion of the shipping process as 
indicated by the terms of the contract, at which point control is transferred to the customer and revenue is recognized. The Company 
has no significant arrangements with multiple performance obligations. Remaining performance obligations consist of the aggregate 
amount  of  the  total  transaction  price  that  is  unsatisfied  or  partially  satisfied. As  of  December  31,  2018,  our  total  remaining 
performance obligations are immaterial. The Company recognizes sales-based royalty revenue under third-party license agreements 
as the related sales are made by licensees.

The terms of a contract or historical business practice can give rise to variable consideration, including customer discounts, rebates, 
and returns. The Company estimates variable consideration using either the expected value or most likely amount method. We 
include estimated amounts in the transaction price to the extent it is probable that a significant reversal of revenue will not occur 
in  a  subsequent  reporting  period.  Our  estimates  of  variable  consideration  are  based  on  all  reasonably  available  information 
(historical, current, and forecasted). Rebates are recognized over the contract period based on expected revenue levels. Sales 
discounts and rebates totaled $8.1 million, $9.1 million, and $8.7 million for the years ended December 31, 2018, 2017, and 2016, 
respectively. Returns and allowances totaled $7.7 million, $8.5 million, and $5.1 million for the years ended December 31, 2018, 
2017, and 2016, respectively.

The Company elected to account for shipping and handling activities that occur after control of the related good transfers to the 
customer as fulfillment activities rather than evaluating such activities as performance obligations. As a result, all shipping and 
handling costs related to contracts with customers are recognized in the Cost of goods sold line on the Consolidated Statements 
of Earnings, which is consistent with our historical practice. Additionally, the Company elected to apply the practical expedient 
allowing incremental costs of obtaining a contract to be expensed as incurred if the amortization period of the resulting asset would 
have been less than one year. These costs primarily consist of sales commissions and the Company has no such significant costs 
exceeding the one year limit for applying the practical expedient.

Receivables, net from contracts with customers were $128.6 million and $127.0 million as of December 31, 2018 and January 1, 
2018, respectively. See Note 17. Segment Information for disclosures regarding the disaggregation of revenues.

2. Disposed and Discontinued Operations

Management and the Board of Directors periodically conduct strategic reviews of the Company's businesses.

On November 28, 2017, the Company completed the sale of its Timing Device Business, part of the PD segment, for $130.0 
million, plus purchase price adjustments for a net amount of $135.1 million. The Company recorded a gain of $63.9 million as a 
result of the sale, which included $0.4 million of gain amounts reclassified from Accumulated other comprehensive loss into 
earnings related to currency translation adjustments. The purchase price included $10.0 million held in escrow that was received 
during the third quarter of 2018 and was previously recorded in the Prepaid and other current assets line on the Consolidated 
Balance Sheets.

On July 7, 2016, the Company completed the sale of its Speaker and Receiver Product Line for $45.0 million in cash, less purchase 
price adjustments for a net amount received of $40.6 million. The Company recorded a loss of $25.6 million as a result of the sale, 
which included $26.9 million of loss amounts reclassified from Accumulated other comprehensive loss into earnings related to 
currency translation adjustments. 

The results of operations and financial positions of the Timing Device Business and Speaker and Receiver Product Line have been 
reclassified to discontinued operations for all periods presented as these disposals represent strategic shifts that have a major effect 
on the Company's results of operations.

3. Acquisitions

On January 19, 2018, the Company acquired substantially all of the assets of Compex for $16.0 million, plus purchase price 
adjustments for a net amount of $18.7 million. The asset purchase agreement relating to the acquisition provided for a $0.6 million
post-closing working capital adjustment that settled on April 2, 2018 as well as a $1.0 million holdback that will be paid eighteen 
months from the completion of the acquisition and is recorded in the Other accrued expenses line on the Consolidated Balance 
Sheets. The acquired business provides single layer electronic components to the telecommunication, fiber optics, defense, and 
aerospace markets. The transaction was accounted for under the acquisition method of accounting and the results of operations 
are included in the Consolidated Financial Statements from the date of acquisition in the PD segment. Included in the Consolidated 
Statements of Earnings are Compex's revenues and earnings before income taxes of $12.6 million and $3.4 million, respectively, 
from the date of acquisition through December 31, 2018.

Compex Intangible Assets Recorded

Customer relationships, unpatented technologies, and trademarks will be amortized over estimated useful lives of 10 years, 8 years, 
and 5 years, respectively. The fair value for customer relationships was determined using the excess earnings method under the 
income approach. The fair values of unpatented technologies and trademarks were determined using the relief from royalty method 
under the income approach. The fair value measurements of intangible assets are based on significant unobservable inputs, and 
thus represent Level 3 inputs. Significant assumptions used in assessing the fair values of intangible assets include discounted 
future cash flows, customer attrition rates, and royalty rates.

The excess of the total purchase price over the total fair value of the identifiable assets and liabilities was recorded as goodwill. 
The goodwill recognized is primarily attributable to the assembled workforce and synergies. None of the goodwill resulting from 
this acquisition is tax deductible. Goodwill has been allocated to the PD segment, which is the segment expected to benefit from 
the acquisition.

Impact of Compex Acquisition and Pro-forma Summary

The following unaudited pro-forma summary presents consolidated financial information as if Compex had been acquired on 
January 1, 2017. The unaudited pro-forma financial information is based on historical results of operations and financial positions 
of the Company and Compex. The pro-forma results include estimated amortization of definite-lived intangible assets and the 
estimated depreciation expense of the fixed asset step-up to fair value. The pro-forma results exclude transaction costs and the 
estimated cost of the inventory step-up to fair value.

The  unaudited  pro-forma  financial  information  does  not  necessarily  represent  the  results  that  would  have  occurred  had  the 
acquisition occurred on January 1, 2017. In addition, the unaudited pro-forma information should not be deemed to be indicative 
of future results.

On January 11, 2017, the Company completed an acquisition of certain assets of a capacitors manufacturer for cash consideration 
of $3.7 million, of which $2.5 million was paid during the year ended December 31, 2017. An additional $1.0 million was paid 
during the year ended December 31, 2018, with the remaining $0.2 million to be paid in the first quarter of 2019. The financial 
results of this acquisition were included in the Consolidated Financial Statements from the date of acquisition within the PD 
segment.  In  connection  with  the  acquisition,  the  Company  recorded  an  intangible  asset  of  $3.3  million  related  to  customer 
relationships that will be amortized over an estimated useful life of 5 years. Pro-forma financial information has not been provided 
as the acquisition did not have a material impact on the Consolidated Statements of Earnings.

4. Impairments

The Company evaluates long-lived assets for recoverability whenever events or changes in circumstances indicate that the carrying 
amount may not be recoverable. There were no asset impairments recorded during the year ended December 31, 2018. During the 
second quarter of 2017, an updated strategic plan was completed for Audio segment product lines. The updated strategic plan 
identified a decline of future demand for a specific product line, which indicated projected future cash flows may not be sufficient 
to recover the carrying value of the associated unpatented technologies and property, plant, and equipment assets. The utilization 
of undiscounted future cash flows was used to determine recoverability of the long-lived assets. The fair value of the intangibles 
was determined through the use of discounted cash flows, and the fair value of fixed assets was determined using their liquidation 
value. As a result of this analysis, the Company concluded that the fair values of these long-lived assets were less than their 
respective carrying values. The Company recorded total impairment charges of $21.3 million, of which $5.1 million was related 
to  fixed  assets  and  $16.2  million  was  related  to  intangible  assets. The  Company  recorded  $1.4  million  of  the  charges  within 
Impairment charges in Gross profit and recorded $19.9 million within the Impairment charges line item in Operating expenses 
within the Consolidated Statements of Earnings.

During the year ended December 31, 2016, the Company identified asset impairments within the Audio segment of $0.5 million, 
which are primarily related to restructuring actions to focus research and development efforts on the design of new products in 
our core business. The Company recorded $0.3 million within Impairment charges in Gross profit and $0.2 million within the 
Impairment charges line item in Operating expenses within the Consolidated Statements of Earnings.

10. Hedging Transactions and Derivative Instruments

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company is affected by changes in certain market conditions. These changes in market conditions may adversely impact the 
Company’s financial performance and are referred to as "market risks." The Company uses derivatives as a risk management tool 
to mitigate the potential impact of certain market risks, which are primarily foreign currency risk and interest rate risk related to 
ongoing business operations.

Cash Flow Hedging

The Company uses cash flow hedges to minimize the variability in cash flows of assets, liabilities, or forecasted transactions caused 
by fluctuations in foreign currency exchange rates or market interest rates. These derivatives, which are designated cash flow 
hedges, are carried at fair value. The changes in their fair values are recorded to Accumulated Other Comprehensive Income (Loss) 
("AOCI") and reclassified in current earnings when the hedge contract matures or becomes ineffective.

To manage its exposure to foreign currency exchange rates, the Company has entered into currency deliverable forward contracts. 
These derivative instruments allow the Company to hedge portions of its forecasted intercompany sales, which are expected to 
occur within the next twelve months and are denominated in non-functional currencies. The Company maintains a foreign currency 
cash flow hedging program primarily to reduce the risk that the net U.S. dollar cash inflows from non-U.S. dollar sales and non-
U.S. dollar net cash outflows from procurement activities will be adversely affected by changes in foreign currency exchange 
rates. At December 31, 2018 and 2017, the notional value of the derivatives related to currency forward contracts, principally the 
Chinese yuan, Malaysian ringgit, and Philippine peso, was $41.6 million and $17.9 million, respectively.

To manage its exposure to market risk for changes in interest rates, the Company entered into an interest rate swap on November 
12, 2014 to convert variable interest rate payments into a fixed rate on a notional amount of $100.0 million of debt for monthly 
interest payments that began in January 2016. The Company designated the swap as a cash flow hedge with re-measurement gains 
and losses recorded through AOCI. In December 2017, the Company entered into a partial termination of the interest rate swap 
and reduced the notional amount to $50.0 million. The interest rate swap ended in July 2018. 

Economic (Non-Designated) Hedging

In addition to derivative instruments that are designated and qualify for hedge accounting, the Company also uses certain derivatives 
as economic hedges of foreign currency risk. Although these derivatives were not designated and/or did not qualify for hedge 
accounting, they are effectively economic hedges. The changes in fair value of these economic hedges are immediately recognized 
in earnings.

The Company uses foreign currency economic hedges to offset the earnings impact that fluctuations in foreign currency exchange 
rates have on certain monetary assets and liabilities denominated in non-functional currencies. The Company does not enter into 
these hedges for speculative reasons. These derivatives are carried at fair value with changes in fair value immediately recognized 
in earnings within Other expense (income), net. In addition, these derivative instruments minimize the impact of exchange rate 
movements on the Company’s balance sheet, as the gains or losses on these derivatives are intended to offset gains and losses from 
the reduction of the hedged assets and liabilities. At December 31, 2018 and 2017, the notional value of the derivatives related to 
economic hedging was $19.8 million and $6.4 million, respectively. 

The notional amounts of the derivative financial instruments do not necessarily represent amounts exchanged by the parties and, 
therefore, are not a direct measure of our exposure to the financial risks described above. The amounts exchanged are calculated 
by reference to the notional amounts and by other terms of the derivatives, such as interest rates, foreign currency exchange rates, 
or other financial indices. The Company does not view the fair values of its derivatives in isolation, but rather in relation to the 
fair values or cash flows of the underlying hedged transactions or other exposures. Virtually all of our derivatives are straightforward 
over-the-counter instruments with liquid markets.

70

Fair Value Measurements

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

All  derivatives  are  carried  at  fair  value  on  the  Company’s  Consolidated  Balance  Sheets. ASC  820,  Fair Value  Measurement, 
establishes a fair value hierarchy that requires the Company to maximize the use of observable inputs and minimize the use of 
unobservable inputs when measuring fair value. A financial instrument’s categorization within the hierarchy is based on the lowest 
level of input that is significant to the fair value measurement. ASC 820 establishes three levels of inputs that may be used to 
measure fair value as follows:

Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 - Observable inputs other than quoted prices included in Level 1, such as quoted prices in active markets for 
similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or 
other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets 
or liabilities.

Level 3 - Unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own 
assumptions.

The Company determines the fair values of its derivatives based on standard valuation models or observable market inputs such 
as quoted market prices, foreign currency exchange rates, or interest rates; therefore, the Company classifies the derivatives within 
Level 2 of the valuation hierarchy.

The Company early adopted ASU 2017-12 as of January 1, 2018. The standard requires adoption of the amended presentation and 
disclosure requirements on a prospective basis. With respect to presentation requirements, the Company began presenting the 
impact of foreign exchange contracts qualifying as cash flow hedges within the Cost of goods sold line on the Consolidated 
Statements of Earnings as of January 1, 2018. These amounts were classified in the Other expense (income), net line in prior 
periods. This change aligns the presentation of the impact of these hedges with the same line on the Consolidated Statements of 
Earnings that is used to present the earnings effect of the hedged item. With respect to disclosure requirements, the Company has 
enhanced the tabular disclosures below to align with the standard. See Note 1. Summary of Significant Accounting Policies for 
additional information on the adoption of this standard.

3.25% Convertible Senior Notes Due November 1, 2021

In May 2016, the Company issued $172.5 million aggregate principal amount of 3.25% convertible senior notes due November 
1,  2021  (the  "Notes"),  unless  earlier  repurchased  by  the  Company  or  converted  pursuant  to  their  terms.  Interest  is  payable 
semiannually in arrears on May 1 and November 1 of each year and commenced on November 1, 2016.

The Notes are governed by an Indenture (the "Indenture") between the Company, as issuer, and U.S. Bank National Association 
as trustee. Upon conversion, the Company will pay or deliver cash, shares of the Company's common stock, or a combination of 
cash and shares of common stock, at the Company's election. The initial conversion rate is 54.2741 shares of common stock per 
$1,000 principal amount of Notes. The initial conversion price is $18.4250 per share of common stock. The conversion rate will 
be subject to adjustment upon the occurrence of certain specified events but will not be adjusted for accrued and unpaid interest. 
In addition, upon the occurrence of a make-whole fundamental change (as defined in the Indenture), the Company may be required, 
in certain circumstances, to increase the conversion rate by a number of additional shares for a holder that elects to convert its 
Notes in connection with such make-whole fundamental change.

72

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Prior to the close of business on the business day immediately preceding August 1, 2021, the Notes will be convertible only under 
the following circumstances:

during any calendar quarter and only during such calendar quarters, if the last reported sale price of the Company’s common 
stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the 
last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on 
each applicable trading day;

during the five business day period after any 10 consecutive trading day period (the “measurement period”) in which the 
trading price per $1,000 principal amount of Notes was less than 98% of the product of the last reported sale price of the 
Company’s common stock and the conversion rate on each such trading day; or 

upon the occurrence of specified corporate events.

On or after August 1, 2021 until the close of business on the second scheduled trading day immediately preceding the maturity 
date, holders may convert all or any portion of their Notes, in multiples of $1,000 principal amount, at the option of the holder 
regardless of the foregoing circumstances. As of December 31, 2018, no event has occurred that would permit the conversion of
the Notes. The Notes are the Company’s senior unsecured obligations.

In accounting for the issuance of the Notes, the Company separated the Notes into liability and equity components. The carrying 
amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated 
convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting 
the fair value of the liability component from the face value of the Notes as a whole. The excess of the principal amount of the 
liability component over its carrying amount is amortized to interest expense over the term of the Notes. The equity component 
is not remeasured as long as it continues to meet the conditions for equity classification.

In accounting for the transaction costs related to the Notes issuance, the Company allocated the total amount incurred to the liability 
and equity components based on their relative values. Issuance costs attributable to the liability component, totaling $5.0 million, 
are being amortized to interest expense over the term of the Notes, and issuance costs attributable to the equity component, totaling 
$1.3 million, were netted with the equity component in stockholders' equity. Additionally, the Company recorded a deferred tax 
asset of $0.5 million on a portion of the equity component transaction costs which are deductible for tax purposes and immediately 
recorded a valuation allowance against this deferred tax asset.

To minimize the impact of potential economic dilution upon conversion of the Notes, the Company entered into convertible note 
hedge transactions (the “Note Hedges”) with respect to its common stock. In the second quarter of 2016, the Company paid an 
aggregate amount of $44.5 million for the Note Hedges. The Note Hedges will expire upon maturity of the Notes. The Note Hedges 
are intended to offset the potential dilution upon conversion of the Notes and/or offset any cash payments the Company is required 
to make in excess of the principal amount upon conversion of the Notes in the event that the market value per share of the Company's 
common stock, as measured under the Note Hedges, is greater than the strike price of the Note Hedges, which initially corresponds 
to the initial conversion price of the Notes and is subject to anti-dilution adjustments substantially similar to those applicable to 
the conversion rate of the Notes. The Note Hedges are separate transactions entered into by the Company, and are not part of the 
Notes or the Warrants, and have been accounted for as part of additional paid-in capital. Holders of the Notes do not have any 
rights with respect to the Note Hedges.

Warrants

In addition to the Note Hedges, in the second quarter of 2016, the Company entered into warrant transactions, whereby the Company 
sold warrants to acquire shares of the Company's common stock at a strike price of $21.1050 per share (the “Warrants”). The 
Company received aggregate proceeds of $39.1 million from the sale of the Warrants. If the market price per share of the Company's 
common stock for the reporting period, as measured under the Warrants, exceeds the strike price of the Warrants, the Warrants 
could have a dilutive effect on the Company's common stock, unless the Company elects, subject to certain conditions, to settle 
the Warrants in cash. The Warrants are separate transactions entered into by the Company, and are not part of the Notes or the Note 
Hedges, and have been accounted for as part of additional paid-in capital. Holders of the Notes and Note Hedges do not have any 
rights with respect to the Warrants.

On October 11, 2017, the Company entered into a Revolving Credit Facility Agreement (the "New Credit Facility"). The New 
Credit Facility contains a five-year senior secured revolving credit facility providing for borrowings in an aggregate principal 
amount at any time outstanding not to exceed $400.0 million. Up to $100.0 million of the New Credit Facility will be available 
in Euro, Sterling, and other currencies requested by the Company and agreed to by each Lender and up to $50.0 million of the 
New Credit Facility will be made available in the form of letters of credit denominated in any currencies agreed by the issuing 
bank.

The  New  Credit  Facility  serves  as  refinancing  of  indebtedness  and  terminates  the  Company's Amended  and  Restated  Credit 
Agreement dated as of January 27, 2014, as amended and restated as of December 31, 2014 and supplemented from time to time 
(“Prior Credit Facilities”).

74

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

At any time during the term of the New Credit Facility, the Company will be permitted to increase the commitments under the 
New Credit Facility or to establish one or more incremental term loan facilities under the New Credit Facility in an aggregate 
principal amount not to exceed $200.0 million for all such incremental facilities.

Commitments under the New Credit Facility will terminate, and loans outstanding thereunder will mature, on October 11, 2022; 
provided, that if all the Company’s Notes have not been repaid, refinanced, and/or converted to common stock of the Company 
by April 30, 2021, then the commitments under the New Credit Facility will terminate, and the loans outstanding thereunder will 
mature, on such earlier date.

The interest rates under the New Credit Facility will be, at the Borrowers’ option (1) LIBOR (or, in the case of borrowings under 
the New Credit Facility denominated in Euro, EURIBOR) plus the rates per annum determined from time to time based on the 
total leverage ratio of the Company as of the end of and for the most recent period of four fiscal quarters for which financial 
statements have been delivered (the “Applicable Rate”); or (2) in the case of borrowings denominated in U.S. dollars, alternate 
base rate (“ABR”); provided, however, that any swingline borrowings shall bear interest at the rate applicable to ABR borrowings 
or, prior to the purchase of participations in such borrowings by the Lenders, at such other rate as shall be agreed between the 
Company and the swingline lender.

The interest rate under the New Credit Facility is variable based on LIBOR at the time of the borrowing and the Company’s leverage 
as measured by a total indebtedness to Consolidated EBITDA ratio. Based upon the Company’s total indebtedness to Consolidated 
EBITDA ratio, the Company’s borrowing rate could range from LIBOR + 1.25% to LIBOR + 2.25%. In addition, a commitment 
fee accrues on the average daily unused portion of the New Credit Facility at a rate of 0.20% to 0.35%.

The  New  Credit  Facility  includes  requirements,  to  be  tested  quarterly,  that  the  Company  maintains  (i)  a  minimum  ratio  of 
Consolidated EBITDA to consolidated interest expense of 3.25 to 1.0, (the "Interest Coverage Ratio"), (ii) a maximum ratio of 
Consolidated total indebtedness to Consolidated EBITDA of 3.75 to 1.0 (the "Leverage Ratio"), and (iii) a maximum ratio of senior 
secured indebtedness to Consolidated EBITDA of 3.25 to 1.0 (the "Senior Secured Leverage Ratio"). For these ratios, Consolidated 
EBITDA and consolidated interest expense are calculated using the most recent four consecutive fiscal quarters in a manner defined 
in the New Credit Facility. At December 31, 2018, the Company was in compliance with these covenants and it expects to remain 
in compliance with all of its debt covenants over the next twelve months.

On January 27, 2014, the Company entered into a $200.0 million five-year senior secured revolving credit facility as well as a 
$300.0 million five-year senior secured term loan facility pursuant to a Credit Agreement (the "Original Credit Agreement"), which 
are referred to collectively as the Prior Credit Facilities.

On December 31, 2014, the Company amended its Prior Credit Facilities to (i) increase the amount of the revolving credit facility 
in the Original Credit Agreement to $350.0 million from $200.0 million, (ii) increase the amount of the letter of credit subfacility 
in the Original Credit Agreement to $50.0 million from $25.0 million, (iii) eliminate the swing line subfacility in the amount of 
up to $35.0 million in the Original Credit Agreement, and (iv) reduce to $100.0 million from $250.0 million the amount of additional 
incremental revolving or term loans in the Original Credit Agreement. All other terms and conditions of the Prior Credit Facilities 
remained essentially the same.

On February 9, 2016, the Company entered into a third amendment to its Prior Credit Facilities that includes a permanent reduction 
by the Company of the aggregate revolving commitment under the Prior Credit Facilities from $350.0 million to $300.0 million.

On April 27, 2016, the Company entered into a fourth amendment to its Prior Credit Facilities to permit the Company to execute 
the offering of the Notes and the related transactions.

The weighted-average interest rate on the Company's borrowings under the New Credit Facility and Prior Credit Facilities was  
3.56%, 3.58%, and 3.23% for the years ended December 31, 2018, 2017, and 2016, respectively. The weighted-average interest 
rate on the Company's borrowings under the New Credit Facility and Prior Credit Facilities for the years ended December 31, 
2018, 2017, and 2016 includes interest expense related to the monthly interest rate swap settlements that ended in July 2018. The 
weighted-average commitment fee on the revolving lines of credit was 0.24%, 0.36%, and 0.39% for the years ended December 31, 
2018, 2017, and 2016, respectively.

The Company’s effective tax rate is favorably impacted by two tax holidays granted to us by Malaysia effective through December 
31, 2021. These tax holidays are subject to the Company’s satisfaction of certain conditions, including investment or sales thresholds, 
which the Company expects to maintain. During 2016, the Company applied for and received final approval to modify the terms 
of its main tax holiday in Malaysia, reducing the rate to 7.2% versus the statutory rate of 24.0%, effective January 1, 2017 through 
December 31, 2021. If the Company fails to satisfy such conditions, the Company’s effective tax rate may be significantly adversely 
impacted. The continuing operations benefit of these incentives for the years ended December 31, 2018, 2017, and 2016 is estimated 
to be $13.3 million, $13.8 million, and $16.3 million, respectively. The continuing operations benefit of the tax holidays on a per 
share basis for the years ended December 31, 2018, 2017, and 2016 was $0.15, $0.15, and $0.18, respectively.

The Company recorded valuation allowances of $131.2 million and $99.7 million at December 31, 2018 and 2017, respectively, 
against deferred tax assets from continuing operations as the Company believes it is more likely than not that these assets will not 
be realized. The Company recorded a $1.0 million benefit due to the reassessment of the beginning of year valuation allowance 
primarily related to United Kingdom ("U.K.") operations. Management believes that it is more likely than not that the Company 
will realize the benefits of the remaining deferred tax assets. The amount of the deferred tax asset is considered realizable, however, 
it could be adjusted if estimates of future taxable income during the carryforward period are reduced or increased or if objective 
negative evidence in the form of cumulative losses is no longer present, requiring that additional weight be given to subjective 
evidence such as our projections for growth. 

At December 31, 2018, the Company had $30.8 million of Federal net operating losses that are available, of which $11.9 million
will expire in the next 5 to 10 years and $18.9 million will expire in the next 10 to 20 years. There are $96.6 million of State net 
operating losses that are available between 2019 and 2036. There are $379.3 million of non-U.S. net operating loss carryforwards, 
of which $0.7 million will expire within the next 5 years, $1.9 million will expire in the next 10 to 20 years, and $376.7 million
can be carried forward indefinitely.

The Company has $18.7 million of U.S. federal research and development credits that begin to expire in 2020 and $14.6 million 
of foreign tax credits that begin to expire in 2027. In addition, the Company has $16.8 million of state credits, of which $2.4 million
will expire between 2019 and 2034 if unused, and $14.4 million can be carried forward indefinitely.

The  Company  has  not  provided  for  deferred  taxes  on  the  undistributed  earnings  of  its  international  subsidiaries  totaling 
approximately $1.4 billion. Such earnings are reinvested in foreign jurisdictions and it is currently intended that they will continue 
to be reinvested indefinitely. Our Malaysian principal subsidiary is our primary source of foreign earnings and cash. Any future 
decision to distribute cash from this subsidiary to the U.S. should not result in a material amount of U.S. or foreign taxes.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Unrecognized Tax Benefits

The Company records interest and penalties associated with unrecognized tax benefits as a component of income tax expense. 
During the years ended December 31, 2018 and 2017, the Company recorded a potential interest benefit of $0.3 million and $1.1 
million, respectively. The Company recorded $0.3 million of potential interest expense during the year ended December 31, 2016. 
There was no accrued interest at December 31, 2018. Total accrued interest at December 31, 2017 and 2016 of $0.4 million and 
$1.4 million, respectively, was included in Other liabilities on the Consolidated Balance Sheets. During the years ended December 
31, 2018 and 2017, the Company recorded potential penalty expense of $0.1 million and $0.2 million, respectively. Total accrued 
penalties at December 31, 2018 and 2017 of $0.3 million and $0.2 million, respectively, were included in Other liabilities on the 
Consolidated Balance Sheets. There was no recorded potential penalty expense or accrued penalties at December 31, 2016.

The Company's tax returns are routinely audited by the tax authorities in the relevant jurisdictions. For tax years before 2017, the 
Company is no longer subject to U.S. federal income tax examination. For tax years before 2013, the Company’s Malaysian 
subsidiaries are no longer subject to examination. It is reasonably possible that the gross amount of unrecognized tax benefits will 
decrease by $0.1 million during the next twelve months. Included in the balance of total unrecognized tax benefits at December 31, 
2018  are  potential  benefits  of  $3.5  million,  which  if  recognized,  would  affect  the  effective  rate  on  earnings  from  continuing 
operations. Given the Company's current valuation allowance position, no benefit is expected to result from the reversal of any 
uncertain tax position associated with the acquired attributes.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Compensation expense for stock-based awards is measured based on the fair value of the awards as of the date the stock-based 
awards are granted and adjusted to the estimated number of awards that are expected to vest. Forfeitures are estimated based on 
historical  experience  at  the  time  of  grant  and  revised  in  subsequent  periods  if  actual  forfeitures  differ  from  those  estimates. 
Compensation costs for stock-based awards are amortized over their service period.

Prior to the Separation in 2014, Knowles employees participated in our Former Parent's incentive stock program. Adopted in 
connection with the Separation, the Knowles' Corporation 2014 Equity and Cash Incentive Plan (the "Plan") provided for the 
conversion of certain awards granted under our Former Parent's equity incentive program to Knowles equity awards and authorized 
the  grant  of  several  different  forms  of  benefits,  including  stock  options,  RSUs,  PSUs,  and  stock-settled  appreciation  rights 
("SSARs"). In general, each award is subject to the same terms and conditions as were in effect prior to the Separation, except 
that our Former Parent's performance shares converted to time-based RSUs. In addition, the Company made a grant comprised of 
both stock options and time-based RSUs that vest 50% on the third and fourth anniversaries from the date of the grant. The Company 
also made grants of both stock options and time-based RSUs that vest evenly over each of the first three years following the date 
of the grant. The Company elected to use the straight-line method to attribute the expense over the service period of the awards.

Stock Options and SSARs

The fair value of stock options granted by the Company was estimated on the date of grant using a Black-Scholes option-pricing 
model based on the assumptions shown in the table below.

The determination of expected volatility is based on a blended peer group volatility for companies in similar industries, stage of 
life, and with similar market capitalization since there is not sufficient historical volatility data for Knowles common stock over 
the period commensurate with the expected term of stock options, as well as other relevant factors. The risk-free interest rate is 
based on U.S. government issues with a remaining term equal to the expected life of the stock options. The expected term is the 
period over which our employees are expected to hold their options. It is based on the simplified method from the SEC’s safe 
harbor guidelines. The Company does not currently anticipate paying dividends over the expected term.

The exercise price per share for the stock options granted by the Company was equal to the closing price of Knowles' stock on the 
NYSE on the date of the grant. The period during which options granted by the Company were exercisable was fixed by Knowles' 
Compensation Committee of the Board of Directors at the time of grant. Generally, stock options vest one-third on each of the 
first three anniversaries of the grant date and expire 7 years from the grant date.

RSUs generally vest based on the passage of time. RSUs have a three year vesting schedule and vest one-third on each of the first 
three anniversaries of the grant date. At December 31, 2018, $23.1 million of unrecognized compensation expense related to RSUs 
is expected to be recognized over a weighted-average period of 1.3 years.

PSUs

In February 2018 and 2017, the Company granted PSUs to senior management. In each case, the awards will cliff vest three 
years following the grant date and the number of PSUs that may be earned and vest is based on the Company's revenues and 
stock price performance over a three year performance period. PSUs will be settled in shares of the Company's common stock. 
Depending on the Company's overall performance relative to revenues and stock price, the size of the PSU awards are subject 
to adjustment, up or down, resulting in awards at the end of the performance period that can range from 0% to 225% of the initial 
grant value. The Company will ratably recognize the expense over the applicable service period for each grant of PSUs and 
adjust the expense as appropriate. The fair value of the PSUs is determined by using a Monte Carlo simulation.

14. Commitments and Contingent Liabilities

From time to time, the Company is involved in various legal proceedings and claims arising in the ordinary course of its business, 
including those related to intellectual property, which may be owned by it or others. The Company owns many patents covering 
products, technology, and manufacturing processes. Some of these patents have been and may continue to be challenged by others. 
In appropriate cases, the Company has taken and will take steps to protect and defend its patents and other intellectual property, 
including through the use of legal proceedings in various jurisdictions around the world. Such steps have resulted in and may 
continue to result in retaliatory legal proceedings, including litigation or other legal proceedings in various jurisdictions and forums 
around  the  world  alleging  infringement  by  the  Company  of  patents  owned  by  others.  The  costs  of  investigations  and  legal 
proceedings, particularly multi-forum litigation, relating to the enforcement and defense of the Company’s intellectual property, 
may be substantial. Additionally, in multi-forum disputes, the Company may incur adverse judgments with regard to certain claims 
in certain jurisdictions and forums while still contesting other related claims against the same opposing party in other jurisdictions 
and forums. Although the ultimate outcome of any legal proceeding or claim cannot be predicted with certainty, based on present 
information, including management’s assessment of the merits of the particular claim, the Company does not expect that any 
asserted or unasserted legal proceedings or claims, individually or in the aggregate, will have a material adverse effect on its cash 
flow, results of operations, or financial condition.

Intellectual Property Infringement Claims

The Company may, on a limited customer specific basis, provide contractual indemnities for certain losses that arise out of claims 
that its products infringe on the intellectual property of others. Historically, the Company has not made significant payments under 
such indemnity arrangements. The Company’s legal accruals were not significant at December 31, 2018 and 2017.

Lease Commitments

The Company leases certain facilities and equipment under operating leases, many of which contain renewal options. Total rental 
expense for all operating leases, net of sublease rental income, was $7.3 million, $6.8 million, and $7.8 million for the years ended 
December 31, 2018, 2017, and 2016, respectively. Total sublease rental income was $2.3 million, $2.2 million, and $1.3 million
for the years ended December 31, 2018, 2017, and 2016, respectively. Contingent rentals under the operating leases were not 
significant.

In September 2013, the Company entered into an agreement for two new facilities and related equipment in China. The lease for 
one of the facilities and related equipment began in the fourth quarter of 2014. The Company took possession of the second facility 
and remaining equipment in 2015. The facilities are reflected in the operating leases and the equipment is reflected in the capital 
leases in the table below.

The aggregate future minimum lease payments for capital leases, operating leases, and rental commitments as of December 31, 
2018 are as follows:

15. Employee Benefit Plans

Knowles sponsors its own defined contribution plan. The Company's expense relating to the defined contribution plan was $6.8 
million, $6.4 million, and $6.1 million for the years ended December 31, 2018, 2017, and 2016, respectively.

Knowles sponsors four defined benefit pension plans to certain non-U.S. employees. The two plans in the U.K. and the plan in 
Taiwan are closed to new participants; however, all active participants in these plans continue to accrue benefits. The balance for 
the plan in the Philippines, which is open to new participants, has been included as of December 31, 2018. These plans are considered 
direct obligations of the Company and have been recorded within the accompanying Consolidated Financial Statements.

The Company does not have any other post-retirement employee benefit plans other than the plans mentioned above and the non-
qualified supplemental retirement plan discussed below.

In accordance with ASU 2017-07, the components of net periodic benefit cost (income) other than service cost are presented in  
the Other expense (income), net line on the Consolidated Statements of Earnings. The service cost component is presented within 
the Cost of goods sold, Research and development expenses, and Selling and administrative expenses lines on the Consolidated 
Statements of Earnings based on the nature of services performed by the related employees. The Company expects to amortize an 
actuarial loss of $0.5 million from accumulated other comprehensive loss into net periodic benefit cost (income) during the year 
ended December 31, 2019.

Assumptions

The Company determines actuarial assumptions on an annual basis. The actuarial assumptions used for the Company’s four defined 
benefit plans for non-U.S. participants will vary depending on the applicable country and as such, the tables below include these 
assumptions by country, as well as in total.

The Company’s discount rate assumption is determined by developing a yield curve based on high quality corporate bonds with 
maturities matching the plans’  expected benefit payment streams. The  plans’ expected cash  flows  are  then discounted  by the 
resulting year-by-year spot rates.

Plan Assets

The primary financial objective of the plans is to secure participant retirement benefits. Accordingly, the key objective in the plans’ 
financial management is to promote stability and, to the extent appropriate, growth in the funded status. Related and supporting 
financial objectives are established in conjunction with a review of current and projected plan financial requirements.

As it relates to the funded defined benefit pension plans, the Company’s funding policy is consistent with the funding requirements 
of applicable local non-U.S. laws. The Company is responsible for overseeing the management of the investments of the plans’ 
assets and otherwise ensuring that the plans’ investment programs are in compliance with applicable local law, other relevant 
legislation, and related plan documents. Where relevant, the Company has retained professional investment managers to manage 
the plans’ assets and implement the investment process. The investment managers, in implementing their investment processes, 
have the authority and responsibility to select appropriate investments in the asset classes specified by the terms of their applicable 
prospectus or investment manager agreements with the plans.

The assets of the plans are invested to achieve an appropriate return for the plans consistent with a prudent level of risk. The asset 
return objective is to achieve, as a minimum over time, the passively managed return earned by market index funds, weighted in 
the proportions outlined by the asset class exposures identified in the plans’ strategic allocation. The expected return on assets 
assumption used for pension expense is developed through analysis of historical market returns, statistical analysis, current market 
conditions, and the past experience of plan asset investments.

See Note 10. Hedging Transactions and Derivative Instruments for additional information on the fair value hierarchy. There were 
no significant transfers between Level 1 and Level 2 assets during the years ended December 31, 2018 and 2017.

Fixed income investments include government and municipal securities and corporate bonds, which are valued based on yields 
currently available on comparable securities of issuers with similar credit ratings.

Common stock funds consist of mutual funds and collective trusts. Mutual funds are valued by obtaining quoted prices from 
nationally recognized securities exchanges. Collective trusts are valued using Net Asset Value (the "NAV") as of the last business 
day of the year. The NAV is based on the underlying value of the assets owned by the fund minus its liabilities and then divided 
by the number of shares outstanding. The value of the underlying assets is based on quoted prices in active markets.

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective 
of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other 
market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments 
could result in a different fair value measurement at the reporting date.

In January 2017, the Company changed its allocation of resources and internal reporting structure to facilitate delivering growth 
in its core business. The Company’s operating segments engage in business activities from which they earn revenues and incur 
expenses, have discrete financial information available, and whose financial results are regularly reviewed and used by the chief 
operating decision maker to evaluate segment performance, allocate resources, and determine management incentive compensation. 
The Audio segment aggregates two operating segments into one reportable segment based on similar product applications serving 
our key end markets. The PD segment has one operating segment, which equals its reportable segment. The realignment did not 
change the composition of the Company’s reporting units for goodwill impairment testing purposes. Following these changes, the 
Company's two reportable segments are as follows:

•  Audio Segment

Our Audio group designs and manufactures innovative audio products, including microphones and balanced armature speakers, 
audio processors, and software and algorithms used in applications that serve the mobile, ear, and IoT markets. Locations include 
the sales, support, and engineering facilities in North America, Europe, and Asia, as well as the manufacturing facilities in Asia.

•  PD Segment

Our PD group specializes in the design and delivery of highly engineered capacitors and radio frequency devices for technically 
demanding applications. Our devices are used in applications including power supplies, radar, medical implants, and satellites, 
serving  the  industrial,  defense,  aerospace,  medical,  telecommunications,  and  automotive  markets.  Locations  include  sales, 
support, engineering, and manufacturing facilities in North America, Europe, and Asia. 

90

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company organizes its reportable segments based on how management analyzes performance, allocates capital, and makes 
strategic  and  operational  decisions. These  segments  were  determined  in  accordance  with ASC  280,  Segment  Reporting. The 
segments are aligned around similar product applications serving our key end markets, to enhance focus on end market growth 
strategies.

ITEM  9.  CHANGES  IN AND  DISAGREEMENTS  WITH ACCOUNTANTS  ON ACCOUNTING AND  FINANCIAL 
DISCLOSURE

None.

ITEM 9A.  CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

We conducted an evaluation, under the supervision and with the participation of management, including the chief executive officer 
(“CEO”) and chief financial officer (“CFO”), of the effectiveness of the Company’s disclosure controls and procedures (as defined 
in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2018.

These disclosure controls and procedures are designed to ensure that information required to be disclosed in our reports that are 
filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in 
the SEC’s rules and forms. Our disclosure controls and procedures include, without limitation, controls and procedures designed 
to ensure that this information is accumulated and communicated to management, including the principal executive and principal 
financial officers, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.

94

 
 
 
Based on the evaluation, the CEO and CFO have concluded that these disclosure controls and procedures were effective as of 
December 31, 2018.

(b) Management's Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in 
Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Under management’s supervision, an evaluation of the effectiveness of 
the Company’s internal control over financial reporting was conducted based on the criteria set forth in Internal Control - Integrated 
Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on our 
evaluation  under  the  framework  in  Internal  Control -  Integrated  Framework  (2013) issued  by  the  COSO,  our  management 
concluded that our internal control over financial reporting was effective as of December 31, 2018.

PricewaterhouseCoopers LLP, the Company’s independent registered public accounting firm, has audited the effectiveness of the 
Company’s internal control over financial reporting as of December 31, 2018, as stated in their report which appears herein.

(c) Changes in Internal Control Over Financial Reporting

There has been no change in our internal control over financial reporting that occurred during the fourth quarter of 2018 that has 
materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

(d) Inherent Limitations on Effectiveness of Controls

Our management, including the CEO and CFO, do not expect that our disclosure controls or our internal control over financial 
reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide 
only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must 
reflect the fact that the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations 
in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not 
occur or that all control issues and instances of fraud, if any, will be detected. These inherent limitations include the realities that 
judgments in decision making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also 
be circumvented by the individual acts of some persons, by intentionally falsified documentation, by collusion of two or more 
individuals within Knowles or third parties, or by management override of the controls. The design of any system of controls is 
based in part on certain assumptions about the likelihood of future events and there can be no assurance that any design will succeed 
in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future 
periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the 
degree of compliance with policies or procedures.

Equity and Cash Incentive Plan by 1.75 shares for every one share awarded. Cash performance awards do not count against 
the pool of available shares. The number of shares earned when an award is exercised, vested, or is paid out will count against 
the pool of available shares, including shares withheld to pay taxes or an option’s exercise price. Shares subject to an award
