(a)	General Development of Business

Gentex Corporation (the "Company") designs and manufactures automatic-dimming rearview and non-dimming mirrors and electronics for the automotive industry, dimmable aircraft windows for the aviation industry, and commercial smoke alarms and signaling devices for the fire protection industry. The Company’s largest business segment involves designing, developing, manufacturing and marketing interior and exterior automatic-dimming automotive rearview mirrors that utilize proprietary electrochromic technology to dim in proportion to the amount of headlight glare from trailing vehicle headlamps. Within this business segment, the Company also designs, develops and manufactures various electronics that are value added features to the interior and exterior automotive rearview mirrors as well as interior visors, overhead consoles, and other locations in the vehicle. The Company ships its products to all of the major automotive producing regions worldwide, which it supports with numerous sales, engineering and distribution locations worldwide.

The Company was organized as a Michigan corporation in 1974 to manufacture smoke detectors, a product line that has since evolved to include a variety of fire protection products. In 1982, the Company introduced an interior electro-mechanical automatic-dimming rearview mirror as an alternative to the manual day/night rearview mirrors for automotive applications. In 1987, the Company introduced an interior electrochromic automatic-dimming rearview mirror for automotive applications. In 1991, the Company introduced an exterior electrochromic automatic-dimming rearview mirror for automotive applications. In 1997, the Company began making volume shipments of three new exterior mirror sub-assembly products: thin glass flat, convex and aspheric. In 2005, the Company began making volume shipments of its new bezel-free exterior automatic-dimming mirror. In 2005, the Company announced, and in 2010 began delivering electrochromic dimmable aircraft windows for the aviation industry. In 2013, the Company acquired HomeLink ^® , a wireless vehicle/home communications product that enables drivers to remotely activate garage door openers, entry door locks, home lighting, security systems, entry gates and other radio frequency convenience products for automotive applications, wherein the Company had previously been a licensee of HomeLink ^® and had been, since 2003, integrating HomeLink ^® into its interior automatic-dimming rearview mirrors. In 2015, the Company began making shipments of the Full Display Mirror ^® , which is an on-demand, mirror-borne LCD display that streams live, panoramic video of the vehicle's rearward view in order to improve driver rear vision. Also in 2015, the Company signed an exclusive agreement in the ordinary course of business with TransCore LLP to integrate TransCore's toll module technology into the vehicle in a first-to-market application referred to as Integrated Toll Module ^® or "ITM" ^® . The interior mirror is an optimal location for a vehicle-integrated toll transponder and it eliminates the need to affix multiple toll tags to the windshield.

In 2017, the Company announced an agreement entered into during the ordinary course of business with VOXX to become the exclusive aftermarket distributor of the Gentex Aftermarket Full Display Mirror ^® ("FDM" ^® ) in North America. The Company has also displayed a new three-camera rear vision system that streams rear video – in multiple composite views – to a rearview-mirror-integrated display. Further, the Company has announced an embedded biometric solution for vehicles that leverages iris scanning technology to create a secure environment in the vehicle. There are many use cases for authentication, which range from vehicle security to start functionality to personalization of mirrors, music, seat location and temperature, to the ability to control transactions not only for the ITM ^® system, but also the ride sharing car of the future. The Company believes iris recognition is among the most secure forms of biometric identification, with a false acceptance rate as low as one in 10 million, far superior to facial, voice, and other biometric systems. The Company's future plans include integrating biometric authentication with HomeLink ^® and HomeLink Connect ^TM . The biometric system will allow HomeLink ^® to provide added security and convenience for multiple drivers by activating the unique home automation presets of different authorized users. The Company announced in January 2018 that it completed an exclusive licensing agreement, in the ordinary course of business, with Fingerprint Cards AB to deploy its ActiveIRIS® iris-scanning biometric technology in automotive applications.

In January 2018, the Company announced that an agreement had been signed, in the ordinary course of business, to participate in a round of financing with Yonomi, the Company's partner in home automation technology. The Company is working with Yonomi as a home automation aggregation partner and the Company has developed an app and cloud infrastructure called HomeLink Connect ^TM . HomeLink Connect ^TM is an all-new home automation app that pairs with the vehicle and allows drivers to operate home automation devices from the vehicle's center console display. Drivers of HomeLink Connect ^TM compatible vehicles will be able to download and configure the app to control many available home automation devices and create entire home automation settings.

In January 2019, the Company announced that its latest generation of dimmable aircraft windows will be offered as optional content on the new Boeing 777X.

Automotive revenues represent approximately 98% of the Company's total revenue in 2018, consisting of interior and exterior electrochromic automatic-dimming rearview mirrors and automotive electronics.

Historically, new safety and comfort and convenience options have entered the original equipment automotive market at relatively low rates on “top of the line” or luxury model automobiles. As the selection rates for the options on the luxury models increase, they generally become available on more models throughout the product line. The ongoing trend of domestic and foreign automakers is to offer several options as a package. The Company believes that its automatic-dimming mirrors with and without advanced features will continue to be offered in more option packages, and continue to be available on more small and mid-size vehicle models as consumer awareness of these safety and comfort and convenience features continues to grow, and as the Company continues its efforts to make automakers aware of the Company's technology available on competitive vehicle platforms.

Automotive Rearview Mirrors and Electronics Competition The Company continues to be the leading producer of automatic-dimming rearview mirrors in the world and currently is the dominant supplier to the automotive industry with an approximate 92% market share worldwide in 2018 and an approximate 93% market share in 2017. While the Company believes it will retain a dominant position in automatic-dimming rearview mirrors for some time, another U.S. manufacturer, Magna Mirrors, a division of Magna International Inc. ("Magna"), continues to compete for sales to domestic and foreign vehicle manufacturers and is supplying a number of domestic and foreign vehicle models with its versions of auto-dimming mirrors and may have considerably more resources available to it. As such, Magna may present a formidable competitive threat. The Company also continues to sell automatic-dimming exterior mirror sub-assemblies to Magna Mirrors. In addition, a Japanese manufacturer (Tokai Rika) is currently supplying a few vehicle models in Japan with solid-state electrochromic mirrors. There are also a small number of Chinese domestic mirror suppliers that are marketing and selling automatic-dimming rearview mirrors, in low volume, within the domestic China automotive market. The Company currently believes, however, that these Chinese domestic mirror suppliers do not at this time meet global automotive grade specifications. Additionally, other companies have demonstrated products that are competitive to the Company's Full Display Mirror ^® system, and the Company acknowledges that dimming device (e.g., electrochromic) technology is the subject of research and development efforts by numerous third parties.

Through the Company's HomeLink ^® function, the Company is the sole supplier of integrated wireless in-vehicle communication devices to the automotive industry for communication with garages, gates, parking barriers, and certain home automation products. HomeLink ^® business continues to be awarded to the Company either through its automatic-dimming rearview mirrors, or through HomeLink ^® electronic modules which are integrated into other areas of the automobile (i.e. visors, overhead consoles, and center consoles). In 2014, the Company announced HomeLink ^®

applications for alternative automobiles and vehicle types which include but are not limited to motorcycles, mopeds, snowmobiles, tractors, combines, lawn mowers, loaders, backhoes and golf carts. These product developments will utilize the market leading HomeLink ^® V system of communication to the home, door locks, garage doors, gates, lights, security systems, and an increasing array of home automation products. The Company believes it is being awarded virtually all business in this area and that while the Company believes it continues to maintain a competitive advantage in this area, the increased focus on vehicle and home connectivity through other devices represents a competitive threat to this business. The Company announced in January 2018 the launch of HomeLink Connect™, an extension of the Company's HomeLink ^® feature and an all-new home automation app that pairs with the vehicle and allows drivers to operate home automation devices from the vehicle’s center console display and/or rearview mirror controls. Drivers of HomeLink Connect™ compatible vehicles will be able to download and configure the app to control a myriad of individual home automation devices, or create entire home automation settings.

The Company believes its electrochromic automatic-dimming mirrors and mirrors with advanced electronic features offer significant performance advantages over competing products and the Company makes significant research and development investments to continue to increase and improve the performance advantages of its products.

There are numerous other companies in the world conducting research on various technologies, including electrochromics, for controlling light transmission and reflection. The Company currently believes that the electrochromic materials and manufacturing process it uses for automotive mirrors remains the most efficient and cost-effective way to produce such products. While automatic-dimming mirrors using other technologies may eliminate glare, the Company currently believes that each of these other technologies have inherent cost or performance limitations as compared to the Company's technologies.

As the Company continues to expand its automatic-dimming mirror products with additional advanced electronic features and expands the capabilities of its CMOS imager technology for additional features (i.e. SmartBeam ^® , FDM ^® , driver-assist features, rear video camera, etc.), as well as continuing to expand the capabilities of the Company's CMS technology, the Company recognizes that it is competing with considerably larger and more geographically diverse electronics companies that could present a formidable competitive threat in the future as new products/features and technologies are brought to market.

Dimmable Aircraft Windows

The Company continues to manufacture and sell variable dimmable windows for the passenger compartment on the Boeing 787 Dreamliner Series of Aircraft. In January 2019, the Company announced that it would be offering, as optional content, its latest generation of variable dimmable windows on the Boeing 777X aircraft. The product is scheduled to begin shipping during calendar year 2019.

Markets and Marketing The Company markets its variable dimmable windows to aircraft manufacturers and airline operators globally.

Competition The Company’s variable dimmable aircraft windows are the first commercialized product of its kind for original equipment installation in the aircraft industry. Other manufacturers are working to develop and sell competing products utilizing other technology in the aircraft industry for aftermarket or original equipment installation.

The Company’s success with electrochromic technology provides potential opportunities and use cases for other commercial applications, which the Company continues to explore.

Fire Protection Products

The Company manufactures photoelectric smoke detectors and alarms, visual signaling alarms, photoelectric smoke detectors and electrochemical carbon monoxide alarms, electrochemical carbon monoxide detectors and alarms, audible and visual signaling alarms, and bells and speakers for use in fire detection systems in office buildings, hotels, and other commercial and residential establishments.

Markets and Marketing The Company’s fire protection products are sold directly to fire protection and security product distributors under the Company’s brand name, to electrical wholesale houses, and to original equipment manufacturers of fire protection systems under both the Company’s brand name and private labels. The Company markets its fire protection products primarily in North America, but also globally through regional sales managers and manufacturer representative organizations.

Competition The fire protection products industry is highly competitive in terms of both the smoke detectors and signaling appliance markets. The Company estimates that it competes principally with eight manufacturers of smoke detection

products for commercial use and approximately four manufacturers within the residential market, three of which produce photoelectric smoke detectors. In the signaling appliance markets, the Company estimates it competes with approximately eight manufacturers. While the Company faces significant competition in the sale of smoke detectors and signaling appliances, it believes that the introduction of new products, improvements to its existing products, its diversified product line, and the availability of special features will permit the Company to maintain its competitive position.

Trademarks and Patents

The Company owns 38 U.S. Registered Trademarks and 635 U.S. Patents, of which 31 Registered Trademarks and 514 patents relate to electrochromic technology, automotive rearview mirrors, microphones, displays, cameras, sensor technology, and/or HomeLink ^® products. These patents expire at various times between 2019 and 2037. The Company believes that these patents provide the Company a competitive advantage in its markets, although no single patent is necessarily required for the success of the Company's products.

The Company also owns 309 foreign Registered Trademarks and 787 foreign patents, of which 292 Registered Trademarks and 768 patents relate to electrochromic technology, automotive rearview mirrors, microphones, displays, cameras, sensor technology, and/or HomeLink ^® products. These patents expire at various times between 2019 and 2043. The Company believes that the competitive advantage derived in the relevant foreign markets for these patents is comparable to that experienced in the U.S. market.

The Company owns 50 U.S. Patents and 6 foreign patents that relate specifically to the Company’s variable dimmable windows. The U.S. Patents expire at various times between 2020 and 2037, while the foreign patents expire at various times between 2021 and 2027.

The Company owns 7 U.S. Registered Trademarks, 17 U.S. Patents, 17 foreign Registered Trademarks, and 13 foreign patents that relate to the Company’s fire protection products. The U.S. Patents expire at various times between 2019 and 2035, while the foreign patents expire at various times between 2020 and 2030. The Company believes that the competitive advantage provided by these patents is relatively small.

The Company also has in process 294 U.S. patent applications, 418 foreign patent applications, and 58 Trademark applications. The Company continuously seeks to improve its core technologies and apply those technologies to new and existing products. As those efforts produce patentable inventions, the Company expects to file appropriate patent applications.

In addition, the Company periodically obtains intellectual property rights, in the ordinary course of the Company's business, to strengthen its intellectual property portfolio and minimize potential risks of infringement.

The following risk factors, together with all other information provided in this Annual Report on Form 10-K should be carefully considered.

Automotive Industry. Customers within the auto industry comprise approximately 98% of our net sales. The automotive industry has always been cyclical and highly impacted by levels of economic activity. The current economic environment, while stable, continues to be uncertain and continues to cause increased financial and production stresses evidenced by volatile production levels, volatility with customer orders, supplier part and material shortages, automotive and Tier 1 supplier plant shutdowns, customer and supplier financial issues/bankruptcies, commodity material cost increases and/or supply constraints, consumer vehicle preference shifts, where we may have a lower penetration rate and lower content per vehicle, and supply chain stresses. If automotive customers (including their Tier 1 suppliers) and suppliers experience plant shutdowns, work stoppages, strikes, part shortages, etc., it could disrupt our shipments to these customers, which could adversely affect our business, financial condition, and/or results of operations.

Automakers continue to experience volatility and uncertainty in executing planned new programs which can result in delays or cancellations of new vehicle platforms, package configurations, and inaccurate volume forecasts. This makes it challenging for us to forecast future sales and manage costs, inventory, capital, engineering, research and development, and human resource investments.

Key Customers. We have a number of large customers, including three automotive customers which each account for 10% or more of our annual net sales in 2018 (including direct sales to OEM customers and sales through their Tier 1 suppliers): Volkswagen Group, Toyota Motor Company, and Daimler Group.The loss of all or a substantial portion of the sales to, or decreases in production by, any of these customers (or certain other significant customers) could have a material adverse effect on our business, financial condition, and/or results of operations.

Pricing Pressures. We continue to experience on-going pricing pressures from our automotive customers and competitors, which have affected, and which will continue to affect our profit margins to the extent that we are unable

to offset the price reductions with engineering and purchasing cost reductions, productivity improvements, increases in unit shipments of mirrors and electronics with advanced features, each of which pose an ongoing challenge, which could adversely impact our business, financial condition, and/or results of operations.

Tariffs. The geopolitical environment between the Unites States and other countries, including China and the European Union, continues to cause uncertainty on tariffs. Currently, it is expected that the Unites States will increase tariffs on March 1, 2019 with respect to certain good and materials imported from China, and it is further expected, that China will also increase certain tariffs on goods and materials imported from the United States, unless the two countries enter into a new trade agreement. The continuance of these tariffs and/or escalation of disputes in the geopolitical environment could interfere with automotive supply chains and could have a continued negative impact on the Company’s business, financial condition, and/or results of operations.

Competition . We recognize that Magna Mirrors, our main competitor, may have considerably more resources available to it, and may present a formidable competitive threat.

Additionally, other companies have demonstrated products that are competitive to our Full Display Mirror ^® system, and we acknowledge that dimming device (e.g., electrochromic) technology is the subject of research and development efforts by numerous third parties.

On March 31, 2014, the NHTSA issued a final rule requiring rearview video systems in U.S. light vehicles by May 1, 2018, with a phase-in schedule requirement of 10% of vehicles after May 2016, 40% of vehicles after May 2017, and 100% of vehicles after May 2018. The Company’s RCD mirror application meets all the technical requirements of the NHTSA rule when installed in a vehicle and appropriately paired with an OEM specified camera. The NHTSA rule that rearview video systems are required has increased competition for systems capable of rear video in a variety of locations in the vehicle. Our RCD mirror application has and will continue to be affected by this increased competition.

Our SmartBeam ^® product is a driver-assist feature for headlamp lighting control that competes with other multiple-function driver-assist features that include headlamp lighting control as one of the multiple functions. While we believe SmartBeam ^® is a low cost solution for a safety feature that makes nighttime driving safer by maximizing a vehicle's high-beam usage, competition from multiple-function driver-assist products has already and could continue to impact the success of SmartBeam ^® .

On March 31, 2014 the Alliance of Automobile Manufacturers petitioned the National Highway Traffic Safety Administration to allow automakers to use CMS as an option to replace conventional rearview mirrors within North America, however, no final rule or legislation was made in response to this petition. At the annual SAE Government-Industry Meeting in January 2017, NHTSA requested that SAE develop Recommended Procedures for test protocols and performance criteria for CMS that would replace mirror systems on light vehicles in the U.S. market. SAE assigned the task to the Driver Vision Committee, and the SAE Driver Vision Committee created a CMS Task Force to draft the Recommended Procedures. In the second half of 2018, the Office of Management and Budget published its regulatory and de-regulatory agenda, which included a reference to a pre-rule stage for NHTSA related to amending the existing rear visibility standard to allow the option for camera-monitor systems to replace mirrors. Also, NHTSA published a report dated October 2018 related to camera monitoring systems for outside mirror replacements.

In July 2016, a revision to UN-ECE Regulation 46 was published with an effective date of June 18, 2016, which allows for camera monitor systems to replace mirrors within Japan and European countries. As of January 2017, camera monitoring systems are also permitted as an alternative to replace mirrors in the Korean market. Notwithstanding the foregoing, the Company continues to believe rearview mirrors provide a robust, simple and cost effective means to view the surrounding areas of a vehicle and remain the primary safety function for rear vision today. Cameras when used as the primary rear vision delivery mechanism have some inherent limitations such as: electrical failure; cameras being blocked or obstructed; depth perception challenges; and viewing angle of the camera. Nonetheless, the Company continues designing and manufacturing not only rearview mirrors, but CMOS imagers and video displays as well. The Company believes that combining video displays with mirrors may well provide a more robust product by addressing all driving conditions in a single solution that can be controlled by the driver. The Company has launched a rear vision camera system that streams rear video to a rearview-mirror-integrated display using the Company's Full Display Mirror ^® . This CMS solution uses three cameras to provide a comprehensive view of the sides and rear of the vehicle. The Company also continues to develop in the areas of imager performance, camera dynamic range, lens design, image processing from the camera to the display, and camera lens cleaning. The Company acknowledges that as such technology evolves over time, such as cameras replacing mirrors and/or autonomous driving, there could be increased competition.

Product Mix. We sell products that have varying profit margins. Our financial performance can be impacted depending on the mix of products we sell during a given period. The automotive industry is subject to rapid technological change, vigorous competition, short product life cycles and cyclical, ever-changing consumer demand patterns. When our customers are adversely affected by these factors, we may be similarly affected to the extent that our customers reduce the volume of orders for our products. As a result of such changes and circumstances impacting our customers, sales mix can shift which may have either favorable or unfavorable impact on revenue and would include shifts in regional growth, in OEM sales demand, as well as in consumer demand related to vehicle segment purchases and content penetration. A decrease in consumer demand for specific types of vehicles where we have traditionally provided significant content could have a significant effect on our business, financial condition, and/or results of operations. Our forward guidance and estimates assume a certain geographic sales mix as well as a product sales mix. If actual results vary from this projected geographic and product mix of sales, our business, financial condition, and/or results of operations could be negatively impacted.

Business Combinations. We anticipate that acquisitions of businesses and assets may play a role in our future growth. We cannot be certain that we will be able to identify attractive acquisition targets,have resources available for or obtain financing for acquisitions on satisfactory terms, successfully acquire identified targets or manage timing of acquisitions with capital obligations across our businesses. Additionally, we may not be successful in integrating acquired businesses into our existing operations, achieving projected synergies, and/or maximizing the value of acquired technologies and businesses. Competition for acquisition opportunities in the various industries in which we operate already exists and may increase, thereby potentially increasing our costs of making acquisitions or causing us to refrain from making further acquisitions. We are also subject to applicable antitrust laws and must avoid anticompetitive behavior. These and other acquisition-related factors may negatively and adversely impact our business, financial condition, and/or results of operations.

Intellectual Property. We believe that our patents and trade secrets provide us with a competitive advantage in automotive rearview mirrors, variable dimmable windows,certain electronics, and fire protection products, although no single patent is necessarily required for the success of our products. The loss of any significant combination of patents and trade secrets regarding our products could adversely affect our business, financial condition, and/or results of operations. Lack of intellectual property protection in a number of countries, including China, poses risk for the Company. This trend represents an increasing risk to technology companies in the United States, including the Company.

New Technology and Product Development. We continue to invest a significant portion of our annual sales in engineering, research and development projects. Should these efforts ultimately prove unsuccessful, our business, financial condition, and/or results of operations could be adversely affected.

Intellectual Property Litigation and Infringement Claims. A successful claim of patent or other intellectual property infringement and damages against us could affect business, financial condition, and/or results of operations. If someone claims that our products infringed their intellectual property rights, any resulting litigation could be costly and time consuming and would divert the attention of management and key personnel from other business issues. The complexity of the technology involved in our business and the uncertainty of intellectual property litigation significantly increases these risks and makes such risk part of our on-going business. To that end, we periodically obtain intellectual property rights, in the ordinary course of business, to strengthen our intellectual property portfolio and minimize potential risks of infringement. The increasing tendency of patents granted to others on combinations of known technology is a potential threat to our Company. Any of these adverse consequences could potentially have an effect on our business, financial condition and/or results of operations.

Credit Risk. Certain automakers and Tier 1 customers from time to time may consider the sale of certain business segments or bankruptcy as a result of financial stress. Should one or more of our larger customers (including sales through their Tier 1 suppliers) declare bankruptcy or sell their business, it could adversely affect the collection of receivables, our business, financial condition, and/or results of operations. The current economic environment continues to cause increased financial pressures and production stresses on our customers, which could impact the timeliness of customer payments and ultimately the collectability of receivables.

Our allowance for doubtful accounts primarily relates to financially distressed automotive mirror and electronics customers. We continue to work with these financially distressed customers in collecting past due balances. Refer to Note 1 of the Consolidated Financial Statements for additional details regarding our allowance for doubtful accounts.

Supply Chain Disruptions. Due to the just-in-time supply chains within our business and the automotive industry, a disruption in a supply chain caused by one or more of our suppliers and/or an unrelated Tier 1 supplier due to part shortages, natural disasters, work stoppages, strikes, bankruptcy, etc. could disrupt our shipments to one or more

automakers or Tier 1 customers, which could adversely affect our business, financial condition, and/or results of operations.

Business Disruptions. Manufacturing of our proprietary products employing electro-optic technology is performed at our manufacturing facilities in Zeeland and Holland, Michigan. One of our manufacturing facilities is located in Holland, Michigan, which is approximately three miles from our other manufacturing facilities in Zeeland, Michigan. Should a catastrophic event occur, our ability to manufacture product, complete existing orders and provide other services could be severely impacted for an undetermined period of time. We have purchased business interruption insurance to address some of these potential costs. Our inability to conduct normal business operations for a period of time may have an adverse impact on our business, financial condition, and/or results of operations.

IT Infrastructure . A failure of our information technology ("IT") infrastructure could adversely impact our business, financial condition, and/or results of operations. We rely upon the capacity, reliability and security of our information technology infrastructure and our ability to expand and continually update this infrastructure in response to the changing needs of our business. For example, we have implemented enterprise resource planning and other IT systems in certain aspects of our businesses over a period of several years and continue to update and further implement new systems going forward. These systems may not perform as expected. We also face the challenge of supporting our older systems and implementing necessary upgrades. If we experience a problem with the functioning of an important IT system or a security breach of our IT systems, the resulting disruptions could have an adverse effect on our business, financial condition, and/or results of operations. We, and certain of our third-party vendors, receive and store personal information in connection with our human resources operations and other aspects of our business. Despite our implementation of security measures, our IT systems, like all IT systems, are vulnerable to damages from computer viruses, natural disasters, unauthorized access, cyber-attack and other similar disruptions. Any system failure, accident or security breach could result in disruptions to our operations. A material network breach in the security of our IT systems could include the theft of our intellectual property, trade secrets or customer information. To the extent that any disruptions or security breach results in a loss or damage to our data, or an inappropriate disclosure of confidential or customer information, it could cause significant damage to our reputation, affect our relationships with our customers, lead to claims against the Company and ultimately harm our business, financial condition, and/or results of operations. In addition, we may be required to incur significant costs to protect against damage caused by these disruptions or security breaches in the future.

Employees. Our business success depends on attracting and retaining qualified personnel. Our ability to sustain and grow our business requires us to hire, retain and develop a highly skilled and diverse management team and workforce. Failure to ensure that we have the leadership capacity with the necessary skill sets and experience could impede our ability to deliver our growth objectives and execute our strategic plan. Organizational and reporting changes within management could result in increased turnover. In addition, any unplanned turnover or inability to attract and retain key employees, including managers, could have a negative effect on our business, financial condition and/or results of operations.

Government Regulations. The Dodd-Frank Wall Street Reform and Consumer Protection Act contains provisions to improve transparency and accountability concerning the supply of certain minerals, known as conflict minerals, originating from the Democratic Republic of Congo ("DRC") and adjoining countries. As a result, in August 2012 the SEC adopted annual disclosure and reporting requirements for those companies who use conflict minerals mined from the DRC and adjoining countries in their products. These new requirements required due diligence efforts in 2013, 2014, 2015, 2016, 2017, and 2018, and the Company has disclosed its findings annually to the SEC on Form SD around May 30 each year. As there may be only a limited number of suppliers offering "conflict free" minerals, the Company cannot be sure that we will be able to obtain necessary conflict minerals from such suppliers in sufficient quantities or at competitive prices. Also, the Company may face reputational challenges if we determine that certain of our products contain minerals not determined to be conflict free or if the Company is unable to sufficiently verify the origins for all conflict minerals used in the Company's products through the procedures the Company may implement.

The European New Car Assessment Program ("Euro NCAP") provides an incentive for automobiles sold in Europe to apply safety technologies that include driver assist features such as lane detection, vehicle detection, and pedestrian detection as standard equipment. Euro NCAP compliant driver assist systems are also capable of including high beam assist as a function. The increased application of Euro NCAP on European vehicles could potentially replace the Company's SmartBeam application on these vehicles.

On December 8, 2015, NHTSA proposed changes to the Administration’s 5-Star Safety Ratings for new vehicles (also known as the New Car Assessment Program or NCAP) and initiated a comment period. The proposed changes will,

for the first time, encompass assessment of crash-avoidance technologies, which includes lower beam headlamp performance, semi-automatic headlamp switching, and blind spot detection. NHTSA originally intended to implement the enhancements in NCAP in 2018 beginning with model year 2019 vehicles. The NCAP implementation has been delayed, and on August 5, 2018, NHTSA published a notice seeking public comment on NCAP with a deadline of October 1, 2018 for the submission of written comments. The Company believes that its SmartBeam® technology will qualify with the semi-automatic headlamp NCAP rating system, and that its SmartBeam® technology and exterior mirrors with blind spot alert lighting can be included in a system that qualifies with the lower beam headlamp performance and blind spot detection NCAP rating system, respectively.

On October 12, 2018, NHTSA published a Notice of Proposed Rulemaking ("NPRM") for amendments to Federal Motor Vehicle Safety Standard ("FMVSS") No. 108: Lamps, reflective devices, and associated equipment, and initiated a comment period. The NPRM proposes amendments that would permit the certification of adaptive driving beam head-lighting systems, if the manufacturer chooses to equip vehicles with these systems. NHTSA proposes to establish appropriate performance requirements to ensure the safe introduction of adaptive driving beam head-lighting systems if equipped on newly manufactured vehicles. The Company believes that its dynamic SmartBeam ^® lighting control system (dynamic forward lighting or DFL), which has been sold in markets outside of North America for several years, will meet the requirements of the new FMVSS 108 standards, if amended. The Company's SmartBeam® application has and will continue to be affected by increased competition suppliers of multi-function driver assist camera products, which are able to achieve some of the same functionality as SmartBeam ^® but at a lower cost, due to other suppliers leveraging similar hardware costs, but offering products with multiple software features.

International Operations. We currently conduct operations in various countries and jurisdictions, including purchasing raw materials and other supplies from many different countries around the world, which subjects us to the legal, political, regulatory and social requirements as well as various economic conditions in these jurisdictions. Some of these countries are considered growth markets. International sales and operations, especially in growth markets, subject us to certain risks inherent in doing business abroad, including:


•	Exposure to local economic, political and labor conditions;


•	Unexpected changes in laws, regulations, trade or monetary or fiscal policy, including interest rates, foreign currency exchange rates and changes in the rate of inflation in the U.S. and other foreign countries;


•	Tariffs(as discussed above), quotas, customs and other import or export restrictions and other trade barriers;


•	Brexit, and particularly, an uncontrolled Brexit


•	Expropriation and nationalization;


•	Difficulty of enforcing agreements, collecting receivables and protecting assets through non-U.S. legal systems;


•	Reduced intellectual property protection;


•	Withholding and other taxes on remittances and other payments by subsidiaries;


•	Investment restrictions or requirements;


•	Export and import restrictions;


•	Violence and civil unrest in local countries;


•	Compliance with the requirements of an increasing body of applicable anti-bribery laws, including the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and similar laws of various other countries; and


•	Exposure related to buying, selling and financing in currencies other than the local currencies of the countries in which we operate.

Other. Other issues and uncertainties which could adversely impact our business, financial condition, and/or results of operations include:


•	Volatility in commodity prices may adversely affect our business, financial condition and/or results of operations. If commodity prices rise, and if we are unable to recover these cost increases from our customers, such increases could have an adverse effect on our business, financial condition and/or results of operations;


•	Increasing interest rates impact our financial performance due to an increase in realized losses on the sale of fixed income investments and/or recognized losses due to an Other-Than-Temporary Impairment adjustment on held-to-maturity securities;


•	General economic conditions continue to be of concern in many of the regions in which we do business, given that our primary industry is greatly impacted by overall general economic conditions. Any continued adverse worldwide economic conditions, currency exchange rates, trade war, war or significant terrorist acts, could each affect worldwide automotive sales and production levels;


•	Manufacturing yield issues may negatively impact our business, financial condition and/or results of operations; and


•	Obligations and costs associated with addressing quality issues or warranty claims may adversely affect our business, financial condition and/or results of operations.

Antitakeover Provisions. Our articles of incorporation, bylaws, and the laws of the state of Michigan include provisions that may provide our board of directors with adequate time to consider whether a hostile takeover offer is in our best interest and the best interests of our shareholders. These provisions, however, could discourage potential acquisition proposals and could delay or prevent a change in control.

Fluctuations in Market Price. The market price for our common stock has fluctuated, ranging from a low of $17.80 to a high of $25.41 during 2018. The overall market and the price of our common stock may continue to fluctuate. There may be a significant impact on the market price for our common stock relating to the issues discussed above or due to any of the following:


•	Variations in our anticipated or actual operating results or the results of our competitors;


•	Changes in investors’ or analysts’ perceptions of the risks and conditions of our business and in particular our primary industry;


•	Intellectual property litigation and infringement claims;


•	The size of the public float of our common stock;


•	Market conditions, including the industry in which we operate; and


•	General macroeconomic conditions.

Results of Operations: 2018 to 2017

Net Sales. In 2018, Company net sales increased by $39.2 million , or 2% compared to the prior year. Automotive net sales increased due to a 6% increase in automatic-dimming mirror shipments, from 39.3 million units in 2017 to 41.6 million units in 2018, primarily reflecting increased overall penetration of automatic-dimming mirrors, more so within the Company's international markets than its domestic market. International automotive mirror unit shipments increased 7% in 2018 when compared with the prior year, primarily due to increased penetration of both interior and exterior automatic-dimming mirrors to certain European and Japanese automakers.

Other net sales increased 17% to $42.9 million compared to the prior year, as dimmable aircraft window sales increased 16% year over year and fire protection saw an increase in net sales of 18% year over year.

Cost of Goods Sold. As a percentage of net sales, cost of goods sold increased from 61.3% in 2017 to 62.4% in 2018, primarily due to annual customer price reductions that were not fully offset with purchasing cost reductions, as well as the Company's inability to leverage fixed overhead costs due to lower than expected sales levels. Annual price reductions and fixed overhead costs independently impacted cost of goods sold as a percentage of net sales by approximately 75 - 150 basis points. These negative impacts were partially offset by the impact of purchasing cost reductions of 50 - 75 basis points.

Operating Expenses. Engineering, research and development expenses increased by $7.4 million or 7% from 2017 to 2018, but remained at 6% of net sales. E, R & D increased , primarily due to increased staffing levels which continue to support growth and launch of new business as well as development of new products.

Selling, general and administrative expenses increased by $3.8 million or 5% from 2017 to 2018, but remained at 4% of net sales. The primary reason for the increase from 2017 to 2018 was due to increased staffing levels and travel expenses.

Total Other Income/(Expense). Investment income increased $1.8 million in 2018 versus 2017, primarily due to higher interest rates available for the Company's investable funds. Other income – net increased $3.7 million in 2018 versus 2017, primarily due to decreased interest expense associated with the Company's debt financing and adoption of ASU 2016-1, as discussed further in Note 2 of the Consolidated Financial Statements.

Taxes. The effective tax rate was 16.1% for year ended December 31, 2018 compared to 23.5% the prior year. The effective tax rate in 2017 differed from the statutory federal income tax rate, primarily due to the domestic manufacturing deduction as well as the re-measurement of net deferred tax liabilities as a result of the Tax Cuts and Jobs Act of 2017("Act"). In 2018, the effective tax rate differed from the new statutory federal income tax rate primarily due to the Foreign Derived Intangible Income Deduction. The decrease in the effective tax rate in 2018 from the prior year was due to the change in statutory tax rate as passed in the Act to 21% from 35%.

Net Income. Net income increased by $31.1 million , or 8% year over year, primarily due to the lower effective tax rate on a year over year basis.

Results of Operations: 2017 to 2016

Net Sales. I n 2017, Company net sales increased by $115.9 million, or 7% compared to the prior year. Automotive net sales increased due to a 9% increase in automatic-dimming mirror shipments, from 36.1 million units in 2016 to 39.3 million units in 2017, primarily reflecting increased overall penetration of automatic-dimming mirrors, primarily within the Company's international markets. International automotive mirror unit shipments increased 15% in 2017 when compared with the prior year, primarily due to increased penetration of both interior and exterior automatic dimming mirrors to certain European and Japanese automakers. Other net sales decreased 6% to $36.7 million compared to the prior year, as dimmable aircraft window sales decreased 13% year over year, which was offset by an increase of 2% year over year for fire protection sales.

Cost of Goods Sold. As a percentage of net sales, cost of goods sold increased from 60.2% in 2016 to 61.3% in 2017, primarily due to annual customer price reductions that were not fully offset with purchasing cost reductions, as well as the Company's inability to leverage fixed overhead costs due to negative product mix. Annual price reductions and fixed overhead costs independently impacted cost of goods sold as a percentage of net sales by approximately 100 - 150 basis points. These negative impacts were partially offset by the impact of purchasing cost reductions of 50 - 75 basis points.

Operating Expenses. Engineering, research and development expenses increased by $5.5 million from 2016 to 2017, but remained at 6% of net sales. E, R & D expenses in 2017 increased 6% year over year, compared to calendar year 2016, primarily due to increased staffing levels which continue to support growth and the development of new business. Selling, general and administrative expenses increased by $9.0 million or 14% from 2016 to 2017, but remained at 4% of net sales. The primary reason for the increase from 2016 to 2017 was due to increased staffing levels and travel expenses, as well as approximately $4.4 million in certain previously announced retirement related expenses associated with the retirement of the Company's previous CEO and Chairman of the Board.

Total Other Income/(Expense). Investment income increased $4.7 million in 2017 versus 2016, primarily due to higher year-end mutual fund distribution income. Other income – net increased $5.0 million in 2017 versus 2016, primarily due to increased realized gains on the sale of equity investments and decreased interest expense associated with the Company's debt financing, as discussed further in Note 2 of the Consolidated Financial Statements.

Taxes. The effective tax rate was 23.5% for year ended December 31, 2017 compared to 31.9% the prior year. The effective tax rate in 2016 and 2017 differed from the statutory federal income tax rate, primarily due to the domestic manufacturing deduction for both years, as well as the impacts of the Act. As a result of the Act, the Company re-measured its deferred tax assets and liabilities, which was partially offset by the Company’s transition tax. The total impact of the tax adjustments reduced the Company’s income tax expense during the year by $37.2 million. Pursuant to the guidance within SEC Staff Accounting Bulletin No. 118 (“SAB 118”), as of December 31, 2017, the Company recognized the provisional effects of the enactment of the Tax Legislation for which measurement could be reasonably estimated.

Net Income. Net income increased by $59.2 million, or 17% year over year, primarily due to the lower effective tax rate as well and a 7% percent increase in revenue on a year over year basis.

Liquidity and Capital Resources

The Company’s financial condition throughout the periods presented has remained very strong, in spite of essentially flat production in the Company's primary markets.

The Company's cash and cash equivalents were $217.0 million , $569.7 million and $546.5 million as of December 31, 2018 , 2017 and 2016, respectively. The Company's cash and cash equivalents include amounts held by foreign subsidiaries of $8.3 million, $12.6 million and $7.9 million as of December 31, 2018, 2017 and 2016, respectively.

The Company's current ratio increased from 4.9 as of December 31, 2017 to 5.0 as of December 31, 2018 , reflecting the repayment of $78 million of the Company's short term debt, that was offset by share repurchases,as discussed further in Note 2 of the financial statements. The Company's current ratio decreased from 7.7 as of December 31, 2016, to 4.9 as of December 31, 2017, reflecting the repayment of $107.6 million of the Company's long term debt, and reclassifying the remaining $78 million as short term debt due to the maturity of the Company's term loan in September 2018.

Cash flow from operating activities was $552.4 million , $501.0 million and $477.0 million for the years ended December 31, 2018 , 2017 and 2016, respectively. Cash flow from operating activities increased $51.4 million for the year ended December 31, 2018 compared to the prior year, primarily due to increased net income, partially offset by changes in working capital. Cash flow from operating activities increased $24.0 million for the year ended December 31, 2017, compared the same period in 2016, primarily due to increased net income, partially offset by changes in working capital.

Cash flow used for investing activities for the year ended December 31, 2018 increased by $108.1 million to $185.8 million , compared with $77.7 million , for the year ended December 31, 2017, primarily due to increased investment purchases during the year. Cash flow used for investing activities for the year ended December 31, 2017 decreased by $173.7 million to $77.7 million, compared to the year ended December 31, 2016, primarily due to decreased investment purchases and capital expenditures during the year, as a result of allocation of funds to repay the long-term debt and for common stock repurchases. Capital expenditures for the year ended December 31, 2018 , were $86.0 million , compared with $104.0 million for the prior year, primarily due to decreases in production equipment purchases and building related costs. Capital expenditures for the year ended December 31, 2017 were $104.0 million, compared with $121.0 million for the year ended December 31, 2016, primarily due to decreases in production equipment purchases and building related costs.

Cash flow used for financing activities for the year ended December 31, 2018 , increased $319.3 million to $719.3 million , compared to the year ended December 31, 2017, primarily due to repurchases of common stock of $591.6 million during the calendar year 2018 compared to $231.4 million during the calendar year 2017. Cash flow used for financing activities for the year ended December 31, 2017, increased $169.4 million to $400.0 million compared to the year ended December 31, 2016, primarily due to repurchases of common stock of $231.4 during the calendar year 2017 compared to $163.4 million during the calendar year 2016, repayments of long-term debt of $107.6 million in calendar year 2017 compared to $47.5 million during the calendar year 2016, and an increase of $7.7 million in calendar year 2017 as compared to calendar year 2016 to $108.8 million in dividends paid in calendar year 2017.

Short-term investments as of December 31, 2018 were $169.4 million , up from $152.5 million as of December 31, 2017 and long-term investments were $138.0 million as of December 31, 2018 , up from $57.8 million as of December 31, 2017, due to changes in the Company's overall investment portfolio.

Accounts receivable as of December 31, 2018 decreased $17.6 million compared to December 31, 2017 , primarily due to the timing of sales within each of the comparable periods.

Inventories as of December 31, 2018 , increased $8.5 million compared to December 31, 2017 , primarily due to increased work-in-process and finished goods inventory levels to support first quarter 2019 production and sales forecasts.

Intangible Assets, net as of December 31, 2018 decreased $19.3 million compared to December 31, 2017 , due to the amortization of definite lived intangible assets and patents, discussed further in in Note 10 to the Consolidated Financial Statements.

Accounts payable as of December 31, 2018 , increased $2.9 million compared to December 31, 2017 , primarily due the timing of inventory and capital expenditure payments.

Current portion of long term debt as of December 31, 2018 , decreased $78.0 million compared to December 31, 2017 , due to principal repayments on the Company's long term debt financing in connection with the September 27, 2018 maturity of the Company's debt.

Management considers the Company’s current working capital and long-term investments, as well as its existing credit financing arrangement (notwithstanding covenants prohibiting additional indebtedness), discussed further in Note 2 of the Consolidated Financial Statements, in addition to internally generated cash flow, to be sufficient to cover anticipated cash needs for the foreseeable future considering its contractual obligations and commitments. The following is a summary of working capital and long-term investments:



	2018		2017		2016
Working Capital	$	681,769,335	$	940,916,816	$	1,005,131,050
Long Term Investments	137,979,082		57,782,418		49,894,363
Total	$	819,748,417	$	998,699,234	$	1,055,025,413

The decrease in working capital as of December 31, 2018 is primarily due to increased share repurchases, dividend payments and capital expenditures, which in combination were more than provided by cash flow from operations.

Please refer to Part II, Item 5 , with regard to the Company's previously announced share repurchase plan.

Outlook

The Company utilizes the light vehicle production forecasting services of IHS Markit. IHS Markit current forecasts for light vehicle production for calendar year 2019 are approximately 16.9 million units for North America, 21.9 million units for Europe, 13.3 million units for Japan and Korea and 27.4 million units for China.

The Company currently estimates that top line revenue for calendar year 2019 will be between $1.83 and $1.93 billion. All estimates are based on light vehicle production forecasts in the primary regions to which the Company ships product, as well as the estimated option rates for its mirrors on prospective vehicle models and anticipated product mix. The Company continues to see order rates and booked business that allow for these estimates despite very modest vehicle production increases in our primary markets. Continuing uncertainties, including: light vehicle production levels; supplier part or material shortages; automotive plant shutdowns; sales rates in Europe, Asia and North America; challenging macroeconomic and geopolitical environments, including tariffs; OEM strategies and cost pressures; customer inventory management and the impact of potential automotive customer (including their Tier 1 suppliers) and supplier bankruptcies; work stoppages, strikes, etc., which could disrupt shipments to these customers, make forecasting difficult.

The Company is estimating that the gross profit margin will be between 36% and 37% for calendar year 2019. The aforementioned gross margin estimate includes approximately $20 million in annual costs as a result of tariffs that were put in place in 2018 and proposed increases set to become effective in March 2019. Historically, annual customer price reductions have placed significant pressure on gross margin on an annual basis. Given the current revenue forecast and projected product mix for 2019, the Company believes it may be able to offset some of those annual customer price reductions with purchasing cost reductions and operational efficiencies, but will be limited in certain aspects due to rising commodity costs on certain electronic components and precious metal commodities, in addition to the aforementioned increased costs related to tariffs.

The Company also currently estimates that its operating expenses, which include engineering, research and development expenses and selling, general and administrative expenses are expected to be between $195 and $200 million for calendar year 2019, increased staffing levels which continue to support growth and launch of new business as well as development of new products. The Company is a technology leader in the automotive industry, with a focus on developing uniquely designed solutions that are highly proprietary. The Company continues to make investments to maintain a competitive advantage in its current market as well as to use its core competencies to develop products that are applicable in other markets.

In light of on-going demand for our automatic-dimming mirrors and electronics, the Company currently anticipates that 2019 capital expenditures will be approximately $90 - $100 million, a majority of which will be production equipment purchases. Capital expenditures for calendar year 2019 are currently anticipated to be financed from current cash and cash equivalents on hand and cash flows from operating activities.

The Company also estimates that depreciation and amortization expense for calendar year 2019 will be approximately $105 - $115 million.

The Company is further estimating that its tax rate will be between 16.0% and 18.0% for calendar year 2019.

In accordance with its previously announced share repurchase plan and capital allocation strategy, the Company intends to continue to repurchase additional shares of its common stock in 2019 and into the future depending on a number of factors, including: market, economic, and industry conditions; the market price of the Company's common stock; anti-dilutive effect on earnings; available cash; and other factors that the Company deems appropriate.

The Company is also providing top line revenue guidance for calendar year 2020. IHS Markit current forecasts for light vehicle production for calendar year 2020 are approximately 16.4 million units for North America, 22.2 million units for Europe,12.7 million units for Japan and Korea, and 28.6 million units for China. Based on these forecasts, the Company is estimating that revenue for calendar year 2020 will increase approximately 3% to 8% over current estimates provided for 2019 revenue.

Market Risk Disclosure

The Company is subject to market risk exposures of varying correlations and volatilities, including foreign exchange rate risk, and interest rate risk. Fluctuating interest rates could negatively impact the Company's financial performance due to realized losses on the sale of fixed income investments and/or recognized losses due to other-than-temporary impairment adjustments on held-to-maturity securities (mark-to-market adjustments).

The Company has some assets, liabilities and operations outside the United States, including multi-currency accounts, which currently are not significant overall to the Company as a whole. Because the Company sells its automotive mirrors throughout the world and automobile manufacturing is highly dependent on general economic conditions, it could be significantly affected by weak economic conditions in foreign markets that could reduce demand for its products.

Most of the Company’s non-U.S. sales are invoiced and paid in U.S. dollars; during calendar year 2018, approximately 8% of the Company’s net sales were invoiced and paid in foreign currencies (compared to 8% for calendar year 2017 and 7% for calendar year 2016). The Company currently expects that approximately 7% of the Company’s net sales in calendar year 2019 will be invoiced and paid in foreign currencies. The Company does not currently engage in hedging activities of foreign currencies.

The Company does not have any significant off-balance sheet arrangements or commitments that have not been recorded in its Consolidated Financial Statements. See the Contractual Obligations and Other Commitments below.

Contractual Obligations and Other Commitments

The Company had the following contractual obligations and other commitments (in millions) as of December 31, 2018 .



	Total	Less than 1 Year	1-3 Years	3-5 Years	More than 5 Years
Operating leases	2.2	1.4	0.8
Purchase obligations	136.9	136.9	—	—	—
Dividends payable	28.5	28.5	—	—	—
Total	167.6	166.8	0.8

Purchase obligations are primarily for raw material inventory and capital equipment.

Significant Accounting Policies and Critical Accounting Estimates

The preparation of the Company's consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States, requires management to make estimates, assumptions and apply judgments that affect its financial position and results of operations. On an ongoing basis, management evaluates these estimates and assumptions. Management also continually reviews its accounting policies and financial information disclosures.

The Company’s significant accounting policies are described in Note 1 to the Consolidated Financial Statements.

Certain of our accounting policies require management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions are based on our historical experience, the terms of existing contracts, our evaluation of trends in the industry, information provided by our customers and suppliers and information available from other outside sources, as appropriate. However, these estimates and assumptions are inherently subject to a degree of uncertainty. As a result, actual results in these areas may differ significantly from our estimates, as is the case in any application of generally accepted accounting principles.

The Company considers an accounting estimate to be critical if:

• It requires management to make assumptions about matters that were uncertain at the time of the estimate, and

• Changes in the estimate or different estimates that could have been selected would have had a material impact on our financial condition or results of operations.

Revenue Recognition. The Company recognizes revenue in accordance with Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers . Accordingly, revenue is recognized in an amount that reflects the consideration to which the Company expects to be entitled in exchange for promised goods or services when it transfers those goods or services to customers. Sales are shown net of returns, which have not historically been significant. The Company does not generate sales from arrangements with multiple deliverables. The Company generally receives purchase orders from customers on an annual basis. Typically, such purchase order provide the annual terms, including pricing, related to a particular vehicle model. Purchase orders generally do not specify quantities. The Company recognizes revenue based on the pricing terms included in our annual purchase orders. As part of certain agreements the Company is asked to provide customers with annual price reductions. Such amounts are subject to estimate and are accrued as a reduction of revenue as products are shipped to those customers. In addition, the Company has ongoing adjustments to our pricing arrangements with our customers based on the related content, the cost of our products and other commercial factors. Such pricing accruals are adjusted as they are settled with our customers.

Item 9A. Controls and Procedures.

Disclosure Controls and Procedures

Under the supervision of and with the participation of the Company’s management, the Company's CEO and CFO have evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures ([as defined in Exchange Act Rules 13a – 15(e) and 15d – 15(e)]) as of December 31, 2018, and have concluded that the Company’s disclosure controls and procedures are adequate and effective.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a – 15(f) and 15d – 15(f). Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management asserts that the Company has maintained effective internal control over financial reporting as of December 31, 2018.

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 risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2018 , has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report which is included in Part IV of this Form 10K.

During the period covered by this annual report, there have been no changes in the Company’s internal controls over financial reporting that have materially affected or are reasonably likely to materially affect the Company’s internal controls over financial reporting. In addition, there have been no significant changes in the Company’s internal controls or in other factors that could significantly affect internal controls subsequent to December 31, 2018 .

Item 9B. Other Information.

None.

The “Compensation Committee Report” shall not be deemed to be soliciting material or to be filed with the commission.

On February 20, 2019, the Board of Directors, in connection with assessments of executive officers, changes in responsibilities, and/or individual performance, made adjustments to named executive officer compensation, including changes to base salaries, setforth below:



Executive Officer	Position	2018 Base Salary		2019 Base Salary
Steve Downing	President and CEO	$	650,000	$	750,000
Kevin Nash	VP, Finance, CFO and Treasurer	$	340,000	$	400,000
Neil Boehm	VP, Engineering and CTO	$	333,000	$	407,000
Matt Chiodo	VP, Sales	$	336,000	$	380,000
Scott Ryan	VP, General Counsel and Corporate Secretary	$	315,000	$	350,000

The foregoing increases are consistent with the intention of the Compensation Committee of the Board of Directors to move base salaries for officers toward the market median of an established peer group over a three - year period.

Amended and Restated Annual Incentive Performance-Based Bonus Plan

The Board of Directors previously approved the Amended and Restated Annual Incentive Performance-Based Bonus Plan (the "Annual Plan") to further emphasize performance-based compensation. In lieu of participating in the profit-sharing bonus paid to all employees, the Annual Plan provides potential cash-based bonuses for officers based on the achievement of three key performance metrics: Revenue (33.33% weighting); Operating Income (33.33% weighting); and Earnings per Diluted Share (33.33% weighting). The Annual Plan covers all officers, including our named executive officers.

At the beginning of each year, the Compensation Committee reviews and approves a cash bonus target for each officer, as a percentage of base salary for the year. The CEO may earn from 0% - 200% of base salary. The non-CEO named executive officers may earn from 0% to 150% of their base salaries. All performance-related targets are set by, and achievement of targets are approved by , the Compensation Committee and/or the Board of Directors .

For our executive officers, the 2018 Annual Plan payout opportunities applicable to each performance metric are shown in the table below:



Executive Officer	Annual Plan Threshold		Annual Plan Target		Annual Plan Maximum
Steve Downing	25	%	100	%	200	%
Kevin Nash	25	%	75	%	150	%
Neil Boehm	25	%	75	%	150	%
Matt Chiodo	25	%	75	%	150	%
Scott Ryan	25	%	75	%	150	%

The above Threshold was moved to 50% for the President and CEO and 37.5% for the other named executive officers for 2019 to better align with typical market practice. No other changes were made to the Annual Plan target opportunities for executive officers in 2019, as the target and maximum opportunity levels were appropriate based on the competitive pay range for each position. The foregoing payout opportunities are multiplied by the weighting factor of a particular performance metric to determine the amounts of cash bonuses payable to officers to the extent the threshold, target, or maximum for a performance metric is met or exceeded. To the extent performance exceeds the established threshold or target, as applicable, for any performance metric, but does not meet or exceed the established target or maximum, as applicable, linear interpolation is used to determine the pro rata portion of the performance bonus. The Compensation

Committee also has discretion to increase (or decrease) such performance-based bonuses using its judgment, provided that bonuses are not to in any event exceed 250% of the applicable base salary.

In 2018 and 2019, the Annual Plan uses the same three key performance metrics and weighting: Revenue (weighted 33.33%), Operating Income (weighted 33.33%) and Earnings per Diluted Share (33.33%), since such metrics are not only appropriate measures of performance, but also align with the Company's overall business strategy.

In determining whether annual cash bonuses are paid under the Annual Plan, actual performance for the year is measured against specified target levels for each performance metric. The target for the three performance metrics reflects a level of performance, which at the time set was anticipated to be challenging but achievable. The threshold level is set to be reflective of performance at which the Compensation Committee believed a portion of the award opportunity should be earned. The maximum level was set well above the target, requiring significant achievements and reflecting performance at which the Compensation Committee believed an additional 100% of the target award was warranted.

For 2018, pre-established target performance (along with pre-established thresholds and maximums) and actual results for the performance metrics are as follows:



Executive Officer	Weight		Threshold*	Target*	Maximum*	Actual Performance*
Revenue	33.33	%	$1,794,873	$1,930,000	$2,065,000	$1,834,064
Operating Income	33.33	%	$523,359	$554,000	$597,000	$515,001
Earnings per Diluted Share	33.33	%	$1.410	$1.640	$1.780	$1.644

* amounts in thousands (000) except for per share amounts, and may be modified in the discretion of the Compensation Committee as appropriate to ensure the performance metrics are not unsuitable.

Based on actual Revenue, Operating Income, and Earnings per Diluted Share results compared to the pre-established targets (adjusted as appropriate by the Compensation Committee) and performance of the named executive officers, the payments for 2018 under the Annual Plan are shown in the table below:



Executive Officer	2018 Annual Plan Performance Bonus	2018 Annual Plan Discretionary Bonus
Steve Downing	$323,989	$180,000
Kevin Nash	$132,132	$90,000
Neil Boehm	$129,412	$80,000
Matt Chiodo	$130,578	$80,000
Scott Ryan	$122,417	$80,000

For 2019, the Compensation Committee has established thresholds, targets , and maximums for Revenue, Operating Income, and Earnings per Diluted Share as the Annual Plan performance metrics.

2019 Omnibus Incentive Plan and Long-Term Incentive Program

On February 20, 2019, the Corporation implemented a Long-Term Incentive Plan (the "Long-Term Plan"), pursuant to the 2019 Omnibus Incentive Plan ("OIP") approved by the Board of Directors the same day, subject to shareholder approval. The OIP is intended to replace the Company's existing Employee Stock Option Plan, Second Restricted Stock Plan and Non-Employee Director Stock Option Plan if approved by the shareholders. The Long-Term Plan provides officers, including our named executive officers, with incentive awards that serve an important role by balancing other applicable short-term goals with longer term shareholder value creation , while minimizing risk-taking behaviors that could negatively affect long-term results. The OIP and the Long-Term Plan are each exhibits hereto.

The Long-Term Plan uses three-year performance periods and selected performance objectives to determine equity incentive awards so as to balance short-term goals under the Annual Plan, with performance objectives associated with longer-term shareholder value creation under the Long-Term Plan. Under the Long-Term Plan, the Board of Directors and/or the Compensation Committee determines the amount of the long-term incentive awards. Each officer's award opportunity is based on a target dollar value (determined toward the very beginning of the performance period)

as a percentage of base salary assigned to his or her position based on market comparisons for similar positions, using both a peer group and general industry market data. The following target opportunities apply for the 2019-2021 performance period under the Long-Term Incentive Plan:



Executive Officer	Long-Term Plan Target Opportunity Percentage of Base Salary for 2019-2021
Steve Downing	200	%
Kevin Nash	100	%
Neil Boehm	100	%
Matt Chiodo	100	%
Scott Ryan	100	%

Achievement at threshold performance yields 50% of the target award and achievement of the maximum performance yields another 100% of the target award. To the extent performance exceeds the established threshold or target, as applicable, for an applicable performance objective, but does not meet or exceed the established target or maximum, as applicable, linear interpolation is used to determine the pro rata portion of such award.

Seventy percent (70%) of the total value of the target long-term incentive opportunity is delivered through performance share awards ("PSAs") and the other thirty percent (30%) through restricted stock ("RS"). Both PSAs and RS are forms of performance-based incentive compensation because PSAs involve performance objectives that provide direct alignment with shareholder interests and the value of RS fluctuates based on stock price performance.

In addition to requiring achievement of performance objectives in respect of PSAs, PSAs and RS require the executive officers to remain employed with the Company for three years from the grant date (unless the executive officer attains retirement age, departs for good reason, dies, or becomes disabled or a change in control occurs whereby an award may be paid or partially paid).

Performance Shares

The Long-Term Plan is designed to provide PSAs for officers, including our named executive officers. PSAs are tied to the achievement of two performance objectives, each weighted equally: earnings before interest, taxes, depreciation and amortization (EBITDA) and return on invested capital (ROIC), in each case adjusted as determined by the Compensation Committee. Each performance objective is based on a three-year performance period (2019-2021) with a performance range that can result in PSAs of 0% for failure to achieve threshold, 50% of target for achieving threshold, to 200% of the target opportunity for achieving maximum.

EBITDA drives the ability to commit resources to continued growth, but is also a measure of ability to provide shareholder return. It also drives profitable sales growth and optimizes the Company's cost structure. ROIC ensures management uses the Company's capital in an effective manner that drives shareholder value. Since, the value of PSAs is tied to the Company's actual performance in financial objectives, it aligns the officers' interests with those of shareholders. The target opportunities of PSAs for the named executive officers are shown in the table below:



Executive Officer	Number of PSAs Awarded in 2019 (Target) for 2019-2021
Steve Downing	49,575
Kevin Nash	13,220
Neil Boehm	13,451
Matt Chiodo	12,559
Scott Ryan	11,568

Restricted Stock Awards

The other 30% of the total value of the long-term incentive opportunity consists of RS awards. RS incentivizes and rewards executives for improving long-term stock value and serves as a retention tool. Under the Long-Term Plan, RS will generally be granted in February to officers, including our named executive officers, and cliff vest on the third anniversary of the grant. The RS awarded in 2019, based on the target opportunities, for the executive officers are shown in the table below:



Executive Officer	Number of RS Awarded in 2019 (Target) for 2019-2021
Steve Downing	21,246
Kevin Nash	5,666
Neil Boehm	5,765
Matt Chiodo	5,382
Scott Ryan	4,958

All PSAs and RS awards are subject to shareholder approval of the OIP. Such awards are intended to replace historical grants of stock options and restricted stock under the existing plan which the OIP is intended to replace.

Non-qualified Deferred Compensation Plan

The Board of Directors authorized the Company to enter into a non-qualified deferred compensation plan to provide a vehicle for key employees and officers to defer cash compensation on a tax-favored basis. The terms of such a plan have not been finalized but are expected to be typical for plans of this type.

Director Compensation

For 2019, the Board of Directors adjusted the equity compensation for non-employee directors, subject to shareholder approval of the OIP. Under the existing Non-employee Director Stock Option Plan, non-employee directors receive an option to acquire 7,000 shares of the Company's common stock after each Annual Meeting of Shareholders at a price per share equal to the closing price of the Company's common stock on such a date. If the OIP is approved by shareholders thereby replacing the Non-employee Director Stock Option Plan, after each Annual Meeting of Shareholders, non-employee directors will receive a grant of RS equal to $100,000 divided by the average closing price per share of the Company's common stock on the twenty trading days preceding the date of the grant of such RS. Such RS grants will vest on the first anniversary of the grant.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Gentex Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Gentex Corporation and subsidiaries (the Company) as of December 31, 2018 and 2017, the related consolidated statements of income, comprehensive income, shareholders' investment and cash flows for each of the three years in the period ended December 31, 2018, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at 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 U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 22, 2019 expressed an unqualified opinion thereon.

Basis for Opinion

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

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

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Gentex Corporation

Opinion on Internal Control over Financial Reporting

We have audited Gentex Corporation and subsidiaries’ internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Gentex Corporation and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of Gentex Corporation and subsidiaries as of December 31, 2018 and 2017, the related consolidated statements of income, comprehensive income, shareholders' investment and cash flows for each of the three years in the period ended December 31, 2018, and the related notes and our report dated February 22, 2019 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

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

Definition and Limitations of Internal Control Over Financial Reporting

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

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

The Company

Gentex Corporation is a leading supplier of digital vision, connected car, dimmable glass, and fire protection products. The Company’s largest business segment involves designing, developing, manufacturing and marketing interior and exterior automatic-dimming automotive rearview mirrors and various electronic modules. The Company ships its product to all of the major automotive producing regions worldwide, which it supports with numerous sales, engineering and distribution locations worldwide.

A substantial portion of the Company’s net sales and accounts receivable result from transactions with domestic and foreign automotive manufacturers and Tier 1 suppliers. Aircraft windows are sold for use by aircraft manufacturers and a Tier 1 supplier. The Company’s fire protection products are primarily sold to domestic distributors and original equipment manufacturers of fire and security systems. The Company does not require collateral or other security for trade accounts receivable.

Significant accounting policies of the Company not described elsewhere are as follows:

Consolidation

The consolidated financial statements include the accounts of Gentex Corporation and all of its wholly-owned subsidiaries (together the “Company”). All intercompany accounts and transactions have been eliminated.

Cash Equivalents

Cash equivalents consist of funds invested in bank accounts and money market funds that have daily liquidity.

Allowance For Doubtful Accounts

The Company reviews a monthly aging report of all accounts receivable balances starting with invoices outstanding over sixty days. In addition, the Company monitors information about its customers through a variety of sources including the media, and information obtained through on-going interaction between Company personnel and the customer. Based on the evaluation of the above information, the Company estimates its allowances related to customer receivables on historical credit and collections experience, customers current financial condition and the specific identification of other potential problems, including the economic climate. Actual collections can differ, requiring adjustments to the allowances, but historically such adjustments have not been material.

The following table presents the activity in the Company’s allowance for doubtful accounts:



	Beginning Balance		Net Additions/ (Reductions) to Costs and Expenses		Deductions and Other Adjustments			Ending Balance
Year Ended December 31, 2018:
Allowance for Doubtful Accounts	$	2,714,533	$	—	$	32,114		$	2,746,647
Year Ended December 31, 2017:
Allowance for Doubtful Accounts	$	2,917,424	$	—	$	(202,891	)	$	2,714,533
Year Ended December 31, 2016:
Allowance for Doubtful Accounts	$	2,663,477	$	—	$	253,947		$	2,917,424

The Company’s allowance for doubtful accounts primarily relates to financially distressed automotive customers. The Company continues to work with these financially distressed customers in collecting past due balances.

Investments

The Company follows the provisions of ASC 820, Fair Value Measurements and Disclosures, for its financial assets and liabilities, and for its non-financial assets and liabilities subject to fair value measurements. ASC 820 provides a framework for measuring the fair value of assets and liabilities. This framework is intended to provide increased consistency in how fair value determinations are made under various existing accounting standards that permit, or in some cases, require estimates of fair-market value. This standard also expanded financial statement disclosure requirements about a company’s use of fair-value measurements, including the effect of such measurement on earnings. The cost of securities sold is based on the specific identification method.

The Company’s common stocks and certain mutual funds are classified as available for sale and are stated at fair value based on quoted market prices, and as such are classified as Level 1 assets. As of December 31, 2018, the Company has sold/liquidated all of its positions in common stocks and mutual funds. The Company determines the fair value of its government securities, corporate bonds, and certain mutual funds by utilizing monthly valuation statements that are provided by its broker. The broker determines the investment valuation by utilizing the bid price in the market and also refers to third party sources to validate valuations, and as such are classified as Level 2 assets.

The Company's certificates of deposit have remaining maturities of less than one year and are classified as available for sale, and are considered as Level 1 assets. These investments are carried at cost, which approximates fair value.

During the year ended December 31, 2017, the Company made technology investments in certain non-consolidated third-parties for ownership interests of less than 20% . These investments do not have readily determinable fair values, and the Company has not identified any observable events that would cause adjustment of the valuation to date, and therefore these investments are held at cost at a total of $3.85 million as of December 31, 2018. These investments are classified within Long-Term Investments in the consolidated balance sheet and are not included within the tables below.

Assets or liabilities that have recurring fair value measurements are shown below as of December 31, 2018 and December 31, 2017 :

ASC 320, Accounting for Certain Investments in Debt and Equity Securities , as amended and interpreted, provides guidance on determining when an investment is other-than-temporarily impaired. The Company reviews its fixed income investments for any unrealized losses that would be deemed other-than-temporary and require the recognition of an impairment loss in income. If the cost of an investment exceeds its fair value, the Company evaluates, among other factors, general market conditions, the duration and extent to which the fair value is less than cost, and the Company’s intent and ability to hold the investments. Management also considers the type of security, related-industry and sector performance, as well as published investment ratings and analyst reports, to evaluate its portfolio. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded and new cost basis in the investment is established. If market, industry, and/or investee conditions deteriorate, the Company may incur future impairments. No investments were considered to be other-than-temporary impaired in 2018 and 2017 .

Fixed income securities as of December 31, 2018 , have contractual maturities as follows:

Fair Value of Financial Instruments

The Company’s financial instruments consist of cash and cash equivalents, investments, accounts receivable accounts payable, short and long term debt. The Company’s estimate of the fair values of these financial instruments approximates their carrying amounts at December 31, 2018 and 2017 .

Inventories

Inventories include material, direct labor and manufacturing overhead and are valued at the lower of first-in, first-out (FIFO) cost or market. Inventories consisted of the following as of December 31, 2018 and 2017 :



	2018		2017
Raw materials	$	139,058,541	$	139,272,129
Work-in-process	35,386,615		30,481,192
Finished goods	50,836,443		47,012,262
Total Inventory	$	225,281,599	$	216,765,583

Estimated inventory allowances for slow-moving and obsolete inventories are based on current assessments of future demands, market conditions, evaluation of longer lead times for certain electronic components and related management initiatives. If market conditions or customer requirements change and are less favorable than those projected by management, inventory allowances are adjusted accordingly. Allowances for slow-moving and obsolete inventories (which are included, net, in the above inventory values) were $7.8 million and $6.6 million at December 31, 2018 and 2017 , respectively.

Plant and Equipment

Plant and equipment is stated at cost. Depreciation and amortization are computed for financial reporting purposes using the straight-line method, with estimated useful lives of 7 to 30 years for buildings and improvements, and 3 to 10 years for machinery and equipment. Depreciation expense was approximately $79.7 million , $77.0 million and $66.3 million in 2018 , 2017 and 2016 , respectively.

Impairment or Disposal of Long-Lived Assets

The Company reviews long-lived assets, including property, plant and equipment and other intangible assets with definite lives, for impairment whenever events or changes in circumstances indicate that the asset’s carrying amount may not be recoverable. The Company conducts its long-lived asset impairment analysis in accordance with ASC 360-10-15, Impairment or Disposal of Long-Lived Assets . ASC 360-10-15 requires the Company to group assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities and evaluate the asset group against the sum of the undiscounted future cash flows. If the undiscounted cash flows do not indicate the carrying amount of the asset is recoverable, an impairment charge is measured as the amount by which the carrying amount of the asset group exceeds its fair value based on discounted cash flow analysis or appraisals.

Patents

The Company’s policy is to capitalize costs incurred to obtain patents. The cost of patents is amortized over their useful lives. The cost of patents in process is not amortized until issuance. The Company periodically obtains intellectual property rights, in the ordinary course of business, and the cost of the rights are amortized over their useful lives.

Goodwill and Intangible Assets

Goodwill reflects the cost of an acquisition in excess of the fair values assigned to identifiable net assets acquired. The Company reviews goodwill for impairment during the fourth quarter on an annual basis or more frequently if events or changes in circumstances indicate that goodwill might be impaired. The Company performs an impairment review for its automotive reporting unit, which has been determined to be one of the Company’s reportable segments, using either a qualitative approach or quantitative approach which utilizes

GENTEX CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES, continued

a fair value method that incorporates certain assumptions and judgments. The fair value of a reporting unit refers to the price that would be received to sell the unit as a whole in an orderly transaction between market participants at the measurement date. The Company performs a qualitative assessment (step 0) to determine whether it is more likely than not that a reporting unit's fair value is less than its carrying amount. If not, no further goodwill impairment testing is performed. If so, we determine the fair value of the reporting unit. If the fair value of the reporting unit is greater than its carrying amount, goodwill is not considered to be impaired. However, if the fair value of the reporting unit is less than its carrying amount, an impairment change is recorded as the excess of the reporting units carrying value over its fair value.

The assumptions included in the impairment tests require judgment and changes to these inputs could impact the results of the calculations which could result in an impairment charge in future periods if the carrying amount of the reporting unit exceeds its calculated fair value. For the qualitative assessment performed, management considers factors such as macro-economic conditions, industry and market considerations, overall financial performance, and other company-specific events, amongst other factors, in making the determination as to whether it is more likely than not that a reporting unit's fair value is less than its carrying amount. Other than management's internal projections of future cash flows, the primary assumptions used in the step 1 and step 2 impairment tests are the weighted-average cost of capital and long-term growth rates. Although the Company's cash flow forecasts are based on assumptions that are considered reasonable by management and consistent with the plans and estimates management is using to operate the underlying business, there are significant judgments in determining the expected future cash flows attributable to a reporting unit. There have been no impairment charges booked currently or in prior periods in which goodwill existed.

Indefinite lived intangible assets are also subject to annual impairment testing or more frequently if indicators of impairment are identified. Management judgment and assumptions are required in determining the underlying fair value of the indefinite lived intangible assets. While the Company believes the judgments and assumptions used in determining fair value are reasonable, different assumptions could change the estimated fair values and, therefore, impairment charges could be required, which could be material to the consolidated financial statements. The indefinite lived intangible assets were not impaired as a result of the annual test prepared by management for either period presented.

Refer to Note 10, "Goodwill and Intangible Assets" for information regarding the impairment testing performed in calendar year 2018.

Revenue Recognition

The Company’s revenue is generated from sales of its products. Revenue is recognized when obligations under the term of a contract with the customer is satisfied, generally when the product is shipped and legal title has passed to the customer. The Company does not generate sales from arrangements with multiple deliverables. Effective January 1, 2018, the Company adopted ASC Topic 606, Revenue from Contracts with Customers , using the modified retrospective method. This guidance supersedes nearly all existing revenue recognition guidance under US GAAP. The core principle of the guidance is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The Company has drafted its accounting policy for the new standard based on a detailed review of its business and contracts. Refer to Note 11, "Revenue" , for further information.

Advertising and Promotional Materials

All advertising and promotional costs are expensed as incurred and amounted to approximately $2.5 million , $2.6 million and $1.9 million , in 2018 , 2017 and 2016 , respectively.

Repairs and Maintenance

Major renewals and improvements of property and equipment are capitalized, and repairs and maintenance are expensed as incurred. The Company incurred expenses relating to the repair and maintenance of p

lant and equipment of approximately $28.9 million , $24.6 million and $22.1 million , in 2018 , 2017 and 2016 , respectively.

Self-Insurance

The Company is self-insured for a portion of its risk on workers’ compensation and employee medical costs. The arrangements provide for stop loss insurance to manage the Company’s risk. Such costs are accrued based on known claims and an estimate of incurred, but not reported (IBNR) claims. IBNR claims are estimated using historical lag information and other data provided by claims administrators. This estimation process is subjective, and to the extent that future results differ from original estimates, adjustments to recorded accruals may be necessary.

Product Warranty

The Company periodically incurs product warranty costs. Any liabilities associated with product warranty are estimated based on known facts and circumstances and are not significant at December 31, 2018 , 2017 and 2016 . The Company does not offer extended warranties on its products.

Income Taxes

The provision for income taxes is based on the earnings reported in the consolidated financial statements. Deferred income tax assets and liabilities are computed for differences between the financial statement and tax basis of assets and liabilities that will result in taxable or deductible amounts in the future. Such deferred income tax asset and liability computations are based on enacted tax laws and rates. The Company applies the provisions of ASC 740 as it relates to uncertainty in income taxes recognized in the Company’s consolidated financial statements. A threshold of more likely than not to be sustained upon examination is applied to uncertain tax positions. The Company deems the estimates related to this provision to be reasonable, however, no assurance can be given that the final outcome of these matters will not vary from what is reflected in the historical income tax provisions and accruals.

Earnings Per Share

The following table reconciles the numerators and denominators used in the calculations of basic and diluted earnings per share (EPS) for each of the last three years:



	2018		2017		2016
Numerators:

Denominators:

Potentially dilutive shares resulting from stock option plans	2,082,563		2,361,092		2,638,544
Denominator for diluted EPS	269,877,349		288,226,089		291,072,316

For the years ended December 31, 2018 , 2017 and 2016 , 698,019 shares, 910,105 shares, and 1,985,849 shares, respectively, related to stock option plans were not included in diluted average common shares outstanding because they were anti-dilutive.

Other Comprehensive Income (Loss)

Comprehensive income (loss) reflects the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. For the Company, comprehensive income represents net income adjusted for unrealized gains and losses on certain investments, derivatives, and foreign currency translation adjustments that are further detailed in Note 9 to the Consolidated Financial Statements.

GENTEX CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Continued)

(1) SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES, continued

Foreign Currency Translation

The financial position and results of operations of the Company’s foreign subsidiaries are measured using the local currency as the functional currency. Assets and liabilities are translated at the exchange rate in effect at year-end. Income statement accounts are translated at the average rate of exchange in effect during the year. The resulting translation adjustment is recorded as a separate component of shareholders’ investment. Gains and losses arising from re-measuring foreign currency transactions into the appropriate currency are included in the determination of net income.

Stock-Based Compensation Plans

The Company accounts for stock-based compensation using the fair value recognition provisions of ASC 718, Compensation - Stock Compensation . As described more fully in Note 5, the Company provides compensation benefits under two stock option plans, a restricted stock plan, and an employee stock purchase plan. The Company utilizes the Black-Scholes model, which requires the input of subjective assumptions. These assumptions include estimating (a) the length of time employees will retain their vested stock options before exercising them (“expected term”), (b) the volatility of the Company’s common stock price over the expected term, (c) the number of options that will ultimately not complete their vesting requirements (“forfeitures”) and (d) expected dividends. Changes in the subjective assumptions can materially affect the estimate of fair value of stock-based compensation and consequently, the related amounts recognized on the consolidated condensed statements of operations.

Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Recent Accounting Standards

Effective January 1, 2018, the Company adopted ASC Topic 606, Revenue from Contracts with Customers , using the modified retrospective method. This guidance supersedes nearly all existing revenue recognition guidance under US GAAP. The core principle of the guidance is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. Based on the new guidance, the Company continues to recognize revenue at a particular point in time for the majority of its contracts with customers, which is generally when products are either shipped or delivered. The adoption of ASC 606 did not have a material impact on the consolidated financial statements. The Company has expanded its consolidated financial statement disclosures in order to comply with the disclosure requirements of the ASU beginning in the first quarter of 2018. These expanded disclosures are included in Note 11 to the Consolidated Financial Statements.

Effective January 1, 2018, the Company adopted ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilitie s. The standard amends various aspects of the recognition, measurement, presentation, and disclosure of financial instruments. The most significant impact to our consolidated financial statements relates to the recognition and measurement of equity investments at fair value with changes recognized in net income. The amendment also updates certain presentation and disclosure requirements. The Company recorded a cumulative-effect adjustment in the first quarter of 2018 of $6,642,727 as a result of the implementation of this guidance, and as a result reclassified the net unrealized gain on available-for-sale equity securities as of January 1, 2018 from other comprehensive income to retained earnings. The adoption of ASU 2016-01 is expected to increase volatility in net income as changes in the fair value of available-for-sale equity investments and changes in observable prices of equity investments without readily determinable fair values will be recorded in net income.

Effective October 1, 2018, the Company adopted ASU 2017-04, Simplifying the Test for Goodwill Impairment . The standard eliminates the second step from the above described goodwill impairment test, which requires a hypothetical purchase price allocation to determine the implied fair value of goodwill. Under the new standard, the goodwill impairment charge will be the excess of the reporting unit's carrying value over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The adoption of ASU 2017-04 did not have a material impact on the Company's consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases , which requires balance sheet recognition of lease liabilities and right-of-use assets for most leases with terms of greater than 12 months. The Company will adopt the standard on the required effective date of January 1, 2019. The new guidance contained in the ASU stipulates that lessees need to recognize a right-of-use asset and a lease liability for substantially all leases (other than leases that meet the definition of a short-term lease). The liability is equal to the present value of lease payments. Treatment in the consolidated statements of income is similar to the current treatment of operating and capital leases. The new guidance is effective on a modified retrospective basis for the Company in the first quarter of its fiscal year ending December 31, 2019. The adoption of ASU 2016-02 is not expected to have a material impact on the consolidated financial statements. The Company will expand its consolidated financial statement disclosures in order to comply with the disclosure requirements of the ASU beginning in the first quarter of 2019. The Company will adopt the standard using the transition option, "Comparatives under 840 option", established by ASU 2018-11, Leases (Topic 842), Targeted Improvements (ASU 2018-11). The Company expects the primary impact upon adoption of the lease standard will be the recording of a right-of-use asset and liability on the consolidated balance sheets in a range of approximately $2 million to $3 million , based on the present value of future lease payments. The Company does not believe the standard will materially affect the consolidated balance sheet, net income, liquidity or debt covenant compliance under current agreements.


(2)	DEBT AND FINANCING ARRANGEMENTS

On September 27, 2013, the Company entered into a credit agreement with certain banks and agents consisting of a revolver and term loan. During the years ended December 31, 2018 and 2017 , the Company made repayments of $78.0 million and $107.6 million respectively, plus accrued interest, on the previously existing term loan, which completed the repayments on the outstanding revolver balance. The Company used cash and cash equivalents to fund the payments. As of December 31, 2018 , there was no outstanding balance on the revolver or the term loan as such credit facility was paid in full and expired in 2018.

On October 15, 2018, the Company entered into a new Credit Agreement providing the Company access to a $150 million senior revolving credit facility (“Revolver”), as previously disclosed. Under the terms of the Credit Agreement, the Company is entitled, to further request an additional aggregate principal amount of up to $100 million , subject to the satisfaction of certain conditions. In addition, the Company is entitled to the benefit of swing loans from amounts otherwise available under the Revolver in the aggregate principal amount of up to $20 million swing loans and to request Letters of Credit from amounts otherwise available under the Revolver in the aggregate principle amount up to $20 million , both subject to certain conditions. The obligations of the Company under the Credit Agreement are not secured, but are subject to certain covenants. As of December 31, 2018, there was no outstanding balance on the Credit Agreement. The Credit Agreement expires on October 15, 2023.

The Credit Agreement contains customary representations and warranties and certain covenants that place certain limitations on the Company.

As of December 31, 2018 , the Company was in compliance with its covenants under the Credit Agreement.

Interest expense for the years ended December 31, 2018 and 2017 are presented within the "Other, net" section of the Consolidated Statements of Income and expenses associated with the term loan and revolver were $0.8 million and $3.0 million , respectively.

(3)	INCOME TAXES

The provision for income taxes is based on the earnings reported in the accompanying consolidated financial statements. The Company recognizes deferred income tax liabilities and assets for the expected future tax consequences of events that have been included in the consolidated financial statements or tax returns. Under this method, deferred income tax liabilities and assets are determined based on the cumulative temporary differences between the financial statement and tax basis of assets and liabilities using enacted tax rates expected to be applied to taxable income in years which those temporary differences are expected to be recovered or settled. Deferred income tax expense is measured by the net change in deferred income tax assets and liabilities during the year.

On December 22, 2017, President Trump signed into law the Tax Cuts and Jobs Act (the “Act”), a tax reform bill which, among other items, reduced the current federal income tax rate to 21% from 35%. The rate reduction was effective as of January 1, 2018, and is permanent.

The Act caused the Company’s deferred income taxes to be revalued during calendar year 2017, resulting in a provisional reduction to income tax expense of $38.4 million in that period. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through income tax expense. Pursuant to the guidance within SEC Staff Accounting Bulletin No. 118 (“SAB 118”), as of December 31, 2017, the Company recognized the provisional effects of the enactment of the Act for which measurement could be reasonably estimated. Adjustments to these provisional amounts that are identified within the subsequent measurement period of up to one year from the enactment date are included as an adjustment to tax expense from continuing operations in the period the amounts are determined. The Company has completed its accounting for the income tax effects of the Act and no material adjustments were recorded during calendar year 2018. The one time transition tax calculation, a separate provision of the Act, was also competed and was not material.

The foreign components of income before the provision for income taxes were not material for the year ended December 31, 2018 , 2017 and 2016 . The components of the provision for income taxes are as follows:

Income taxes paid in cash were approximately $86.9 million , $126.0 million and $144.1 million in 2018 , 2017 and 2016 , respectively.

The Company follows the provisions of the Financial Accounting Standards Codification 740 (“ASC 740”), “Income Taxes.” A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:



	2018			2017			2016

The Company recognizes interest and penalties related to unrecognized tax benefits through the provision for income taxes. The Company has accrued approximately $315,000 and $433,000 for interest as of December 31, 2018 and 2017 , respectively. Interest recorded during 2018 , 2017 and 2016 was not considered significant.

The Company is also subject to periodic and routine audits in both domestic and foreign tax jurisdictions, and it is reasonably possible that the amounts of unrecognized tax benefits could change as a result of an audit.

Based on the current audits in process, the payment of taxes as a result of audit settlements, and the completion of tax examinations, the Company does not expect these to have a material impact on the Company’s financial position or results of operations.

For the majority of tax jurisdictions, the Company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 2014.


(4)	EMPLOYEE BENEFIT PLAN

The Company has a 401(k) retirement savings plan in which substantially all of its employees may participate. The plan includes a provision for the Company to match a percentage of the employee’s contributions at a rate determined by the Company’s Board of Directors. In 2018 , 2017 and 2016 the Company’s contributions were approximately $8.2 million , $7.7 million and $6.5 million , respectively. The increase in each of the years was due to increased employee participation in the plan.

The Company does not provide health care benefits to retired employees.


(5)	STOCK-BASED COMPENSATION PLANS

At December 31, 2018 , the Company had four equity incentive plans which include two stock option plans, a restricted stock plan and an employee stock purchase plan. All of the plans and any material amendments thereto have previously been approved by shareholders.

Employee Stock Option Plan

In May 2014, the Employee Stock Option Plan was approved by shareholders, amending and restating a prior plan. The Company may grant up to 24,000,000 shares of common stock under the plan. The purpose of the plan is to provide an opportunity to use stock options as a means of recruiting new managerial and technical personnel and as a means for retaining certain employees of the Company by allowing them to purchase shares of common stock of the Corporation and thereby have an additional incentive to contribute to the prosperity of the Company.

The Company has granted options on 12,787,960 shares (net of shares from canceled/expired options) under the plan through December 31, 2018 . Under the plan, the option exercise price equals the stock’s market price on date of grant. The options vest after one to five years , and expire after five to ten years .

The fair value of each option grant in the Employee Stock Option Plan was estimated on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions for the indicated periods:



	2018			2017			2016
Dividend yield ⁽¹⁾	2.1		%	2.1		%	2.2		%
Expected volatility ⁽²⁾	26.0		%	26.7		%	33.2		%
Risk-free interest rate ⁽³⁾	2.7		%	2.0		%	1.4		%

(2)	Amount is determined based on analysis of historical price volatility of the Company's common stock. The expected volatility is based on the daily percentage change in the price of the stock over a period equal to the expected term of the option grant.

(3) Represents the U.S. Treasury yield over the expected term of the option grant.


(4)	Represents the period of time that options granted are expected to be outstanding. Based on analysis of historical option exercise activity, the Company has determined that all employee groups exhibit similar exercise and post-vesting termination behavior.

As of December 31, 2018 , there was $8,445,267 of unrecognized compensation cost related to share-based payments which is expected to be recognized over the remaining vesting periods, with a weighted-average period of 1.90 years.

Non-employee Director Stock Option Plan

In 2012, an Amended and Restated Non-employee Director Stock Option Plan, covering a total of 1,000,000 shares of common stock, was approved by shareholders replacing a prior plan. The Company has granted options on 483,940 shares (net of shares from canceled options) under the new director plan and 1,074,480 shares (net of shares from canceled options) under a prior plan through December 31, 2018 . Under the shareholder approved plans, the option exercise price equals the stock's market price on date of grant. The options vest after six months , and expire after ten years .

The fair value of each option grant in the Non-employee Director Stock Option Plans was estimated on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions for the indicated periods:

Employee Stock Purchase Plan

In 2013, the Gentex Corporation Employee Stock Purchase Plan covering 2,000,000 shares of common stock was approved by the shareholders, replacing a prior plan. Under such plan, the Company sells shares at 85% of the stock’s market price at the date of purchase. Under ASC 718, the 15% discounted value is recognized as compensation expense. The following table summarizes shares sold to employees under the 2013 Plan in the years ended December 31, 2018 , 2017 and 2016 :

Restricted Stock Plan

In 2015, an amendment to the Company’s Second Restricted Stock Plan was approved by shareholders. The Plan amendment increased the maximum number of shares that may be subject to awards to 9,000,000 shares and to extend the Plan’s termination date to February 19, 2025. The purpose of this plan is to permit grants of shares, subject to restrictions, to employees of the Company as a means of retaining and rewarding them for performance and to increase their ownership in the Company. Shares awarded under the plan entitle the shareholder to all rights of common stock ownership except that the shares may not be sold, transferred, pledged, exchanged or otherwise disposed of during the restriction period. The restriction period is determined by a committee, appointed by the Board of Directors, but may not exceed ten years . The Company has 2,637,853 shares outstanding and has issued 6,376,394 shares under the plan as of December 31, 2018 . During 2018 , 2017 , and 2016 , 279,420 , 228,630 and 246,660 shares, respectively, were granted with a restriction period of five years , as well as 762,749 and 628,015 share grants during 2018 and 2017, respectively, with a restriction of four years , the cliff vest after the restriction period with no additional restrictions, at market prices ranging from $20.21 to $23.14 in 2018 , $18.97 to $21.33 in 2017 , and $14.70 to $19.69 in 2016 , and has unearned stock-based compensation of $34,824,960 associated with these restricted stock grants. The unearned stock-based compensation related to these grants is being amortized to compensation expense over the applicable restriction periods. Amortization expense of restricted stock for years ended December 31, 2018 , 2017 and 2016 was $8,841,985 , $5,353,339 , and $3,885,042 respectively.


(6)	CONTINGENCIES

The Company is periodically involved in legal proceedings, legal actions and claims arising in the normal course of business, including proceedings relating to product liability, intellectual property, safety and health, employment and other matters. Such matters are subject to many uncertainties and outcomes are not predictable. The Company does not believe, however, that at the current time there are matters that constitute material pending legal proceedings that will have a material adverse effect on the financial position, future results of operations, or cash flows of the Company.

The Company reviews goodwill for impairment during the fourth quarter on an annual basis or more frequently if events or changes in circumstances indicate that goodwill might be impaired. The Company has not recognized any impairment of goodwill in the current or prior periods. The Company continuously monitors for events and circumstances that could negatively impact the key assumptions in determining fair value thus resulting in the need for interim testing, including long-term revenue growth projections, profitability, discount rates, recent market valuations from transactions by comparable companies, volatility in the Company's market capitalization, and general industry, market and macro-economic conditions. No such matters were noted in 2018.

The Intangible Assets and related change in carrying values are set forth in the table below as of December 31, 2018 and December 31, 2017 .

Revenue is recognized when obligations under the terms of a contract with the customer are satisfied. Such recognition generally occurs with the transfer of control of the products at a point in time. The Company's automotive OEM contracts generally include Long Term Supply Agreements ("LTSA") and Purchase Orders ("PO") whereby the LTSA sometimes stipulates the pricing and delivery terms and is evaluated together with a PO, which identifies the quantity, timing, and the type of product to be transferred. Certain customer contracts do not always have an LTSA, in which case, the contracts are governed by the PO from the customer in conjunction with other mutually agreed upon terms and conditions.

The Company does not generate revenue from arrangements with multiple deliverables. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring goods excluding revenue amounts that are transferred to third parties, such as sales, value add, and other taxes the Company collects concurrently with revenue-producing activities. The Company does not incur any incremental cost to obtain contracts. Costs are incurred to fulfill contracts with the OEM. However, such costs are accounted for under ASC 340-10, and are not treated as fulfillment costs under ASC 340-40.

Automotive Products Segment

Automotive Rearview Mirrors and Electronics

The Company manufactures interior electrochromic automatic-dimming rearview mirrors that darken to reduce glare and improve visibility for the driver. These electronic interior mirrors can also include additional electronic features such as compass, microphones, HomeLink ^® , lighting assist and driver assist forward safety camera systems, various lighting systems, various telematics systems, ITM ^® systems, and a wide variety of displays. The Company also ships interior non-automatic-dimming rearview mirrors with features. The Company’s interior electrochromic automatic-dimming rearview mirrors also power the application of the Company’s exterior electrochromic automatic-dimming rearview mirrors that darken to reduce glare and improve visibility for the driver. These electronic exterior mirrors typically range in size and shape per automaker specification, but also include additional features such as turn signal indicators, side blind zone indicators, and courtesy lighting. The Company also ships exterior non-automatic-dimming rearview mirrors with similar electronic features as what is available in its automatic-dimming applications. The Company manufactures other automotive electronics products both inside and outside of the rearview mirror through HomeLink ^® applications in the vehicle including the rearview mirror, interior visor, overhead console, or center console.

For the majority of automotive products, transfer of control and revenue recognition occurs when the Company ships the product from the manufacturing facility to the customer. The Company generally receives payment equal to the price that applies at the time of invoice for most automotive product sales. For any shipments of product that may be subject to retroactive price adjustments that are then being negotiated, the Company

GENTEX CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

records revenue based on the Company’s best estimate of the amount of consideration to which the entity will be entitled in exchange for transferring the promised goods to the customer. The Company's approach is to consider these adjustments to the contract price as variable consideration which is estimated based on the then most likely price amount. Payment terms on automotive part sales to customers range from 15 days to 90 days. Estimated revenue is adjusted at the earlier of when the most likely amount of consideration expected to be received changes or when the consideration becomes fixed.

HomeLink ^® Modules

The Company manufactures and sells HomeLink® Modules individually, as well as in combination with the automotive mirrors and other advanced features, as described above. For the majority of automotive products, transfer of control and revenue recognition occurs when the Company ships the product from the manufacturing facility to the customer.

Other Segment

Dimmable Aircraft Windows

The Company supplies variable dimmable windows for the passenger compartment on the Boeing 787 Dreamliner Series of Aircraft. For dimmable aircraft windows, transfer of control and revenue recognition occurs when the Company ships the product from the manufacturing facility to the customer. Payment terms on dimmable aircraft window sales range from 30 days to 45 days.

Fire Protection Products

The Company manufactures photoelectric smoke detectors and alarms, visual signaling alarms, electrochemical carbon monoxide detectors and alarms, audible and visual signaling alarms, and bells and speakers for use in fire detection systems in office buildings, hotels, and other commercial and residential buildings. For fire protection parts, transfer of control and revenue recognition occurs when the Company ships the product from the manufacturing facility to the customer. Payment terms on fire protection part sales to customers range from 30 days to 75 days.
