PART I

Item 1.    BUSINESS

Overview

Allegion plc ("Allegion," "we," "us" or "the Company") is a leading global provider of security products and solutions that keep people and assets safe and secure in the places where they reside, work and thrive. We create peace of mind by pioneering safety and security with a vision of seamless access and a safer world. Seamless access allows authorized, automated and safe passage and movement through spaces and places in the most efficient and frictionless manner possible. Central to our vision is partnering and developing ecosystems to create a flawless experience and enable an uninterrupted and secure flow of people and assets. We offer an extensive and versatile portfolio of mechanical and electronic security products and solutions across a range of market-leading brands. Our experts across the globe deliver high-quality security products, services and systems, and we use our deep expertise to serve as trusted partners to end-users who seek customized solutions to their security needs.

Allegion Principal Products
Door closers and controls	Doors and door systems
Electronic security products	Electronic, biometric and mobile access control systems
Exit devices	Locks, locksets, portable locks, key systems and services
Time, attendance and workforce productivity systems	Other accessories

Access control security products and solutions are critical elements in every building and home. Many door openings are configured to maximize a room’s particular form and function while also meeting local and national building and safety code requirements and end-user security needs. Most buildings have multiple door openings, each serving its own purpose and requiring different specific access-control solutions. Each door must fit exactly within its frame, be prepared precisely for its hinges, synchronize with its specific lockset and corresponding latch and align with a specific key to secure the door. Moreover, with the increasing adoption of the Internet of Things ("IoT"), security products – including keys – are increasingly linked electronically, integrated into software and popular consumer technology platforms and controlled with mobile applications, creating additional functionality and complexity. Seamless access capitalizes on the ability for multiple products and brands to work in tandem, allowing people and assets to move efficiently and safely by adapting access rights for various settings or use cases. These solutions can also provide insights on usage and traffic patterns to improve hygiene of high-traffic areas, boost efficiency and improve visitor, staff and tenant experiences.

We believe our ability to deliver a wide range of solutions that can be custom configured to meet end-users’ security needs is a key driver of our success. We accomplish this with:

•Our extensive and versatile product portfolio, combined with our deep expertise, which enables us to deliver the right products and solutions to meet diverse security and functional specifications and to successfully and securely integrate into leading technology and systems;

•Our consultative approach and expertise, which enables us to develop the most efficient and appropriate building security and access-control specifications to fulfill the unique needs of our end-users and their partners, including architects, contractors, homebuilders and engineers;

•Our access to and management of key channels in the market, which is critical to delivering our products in an efficient and consistent manner; and

•Our enterprise excellence capabilities, including our global manufacturing operations and agile supply chain, which facilitate our ability to deliver specific product and system configurations to end-users and consumers worldwide, quickly and efficiently.

We believe the security products industry will benefit from several global macroeconomic trends, including:

•Expected growth in global electronic products as end-users adopt newer technologies in their facilities and homes;

•Heightened awareness of security and privacy requirements;

•Increased focus on touchless solutions that help promote a healthy environment; and

•The shift to a digital, interconnected environment.

We operate in three geographic regions: Americas; Europe, Middle East and Africa ("EMEA"); and Asia Pacific. We sell our products and solutions under the following brands:

During the year ended December 31, 2020, we generated Net revenues of $2,719.9 million and Operating income of $403.5 million.

History and Developments

We were incorporated in Ireland on May 9, 2013, to hold the commercial and residential security businesses of what was then Ingersoll Rand plc ("Ingersoll Rand"). On December 1, 2013, we became a stand-alone public company after Ingersoll Rand completed the separation of these businesses from the rest of Ingersoll Rand via the transfer of these businesses from Ingersoll Rand to us and the issuance by us of ordinary shares directly to Ingersoll Rand’s shareholders (the "Spin-off"). Our security businesses have long and distinguished operating histories. Several of our brands were established more than 100 years ago, and many originally created their categories:

•Von Duprin, established in 1908, was awarded the first exit device patent;

•Schlage, established in 1920, was awarded the first patents granted for the cylindrical lock and the push button lock;

•LCN, established in 1926, created the first door closer;

•CISA, established in 1926, devised the first electronically controlled lock; and

•SimonsVoss, established in 1995, created the first keyless digital transponder.

We have built upon these founding legacies since our entry into the security products market through the acquisition of Schlage, Von Duprin and LCN in 1974. Today, we continue to develop and introduce innovative and market-leading products. For example, in 2018, we announced the formation of Allegion Ventures, a corporate venture fund that invests in and helps accelerate the growth of companies that have innovative technologies and products such as touchless access and workspace monitoring solutions that complement our core business solutions. Since its formation, Allegion Ventures has invested nearly $15 million in several early-stage companies that share our pioneering vision and seek to find smart and innovative solutions that help keep people and assets safe and secure in the places where they reside, work and thrive.

Recent examples of successful product launches by Allegion are illustrated in the table below:

Industry and Competition

The global markets we serve encompass institutional, commercial and residential construction and remodeling markets throughout North America, EMEA and Asia Pacific. As end-users continue to adopt newer technologies, including IoT, in their facilities and single and multi-family homes, growth in electronic security products and solutions is expected to outperform growth in mechanical security products and solutions. We also expect the security products industry will continue to benefit from favorable trends such as increased concerns about safety and security, new attention on touchless solutions that help promote a healthy environment and technology-driven innovation that enables seamless access and a better user experience as people and assets traverse multiple locations and facilities.

The security products markets are highly competitive and fragmented throughout the world, with a number of large multi-national companies and thousands of smaller regional and local companies. This high fragmentation primarily reflects local regulatory requirements and highly variable end-user needs. We believe our principal global competitors are Assa Abloy AB and dormakaba Group. We also face competition in various markets and product categories throughout the world, including from Spectrum Brands Holdings, Inc. in the North American residential market. As we move into more technologically advanced product categories, we may also compete against new, more specialized competitors.

Our success depends on a variety of factors, including brand and reputation, product breadth, innovation, integration with popular technology platforms, quality and delivery capabilities, price and service capabilities. As many of our businesses sell through wholesale distribution, our success also depends on building and partnering with a strong channel network. Although price often serves as an important customer decision point, we also compete based on the breadth, innovation and quality of our products and solutions, our ability to custom-configure solutions to meet individual end-user requirements and our global supply chain.

Products and Services

We offer an extensive and versatile portfolio of mechanical and electronic security products and solutions across a range of market-leading brands:

•Locks, locksets, portable locks and key systems and services: A broad array of cylindrical and mortise door locksets, security levers and master key systems that are used to protect and control access and a range of portable security products, including bicycle, small vehicle and travel locks. We also offer locksmith services in select locations;

•Door closers, controls and exit devices: An extensive portfolio of life-safety products and solutions generally installed on fire doors and facility entrances and exits. Door controls include both mechanical door closers and automatic door operators. Exit devices, also known as panic hardware, provide rapid egress to allow building occupants to exit safely in an emergency;

•Electronic security products and access control systems: A broad range of electrified locks, access control systems, key card and reader systems and accessories, including IoT, Bluetooth Low Energy (BLE), Power over Ethernet and cloud-based solutions;

•Time, attendance and workforce productivity systems: Products and services designed to help business customers manage and monitor workforce access control parameters, attendance and employee scheduling. We also offer ongoing aftermarket services in addition to design and installation offerings;

•Doors and door systems: A portfolio of hollow metal, glass and specialty doors and door systems; and

•Other accessories: A variety of additional security and product components, including hinges, door pulls, door stops, bike lights, louvers, weather stripping, thresholds and other accessories, as well as certain bathroom fittings and accessibility aids.

Customers

We sell most of our products and solutions through distribution and retail channels, including specialty distribution, e-commerce and wholesalers. We have built a network of channel partners that help our customers choose the right solution to meet their security needs and help commercial and institutional end-users fulfill and install orders. We also sell through a variety of retail channels, including large do-it-yourself home improvement centers, multiple online and e-commerce platforms, as well as small, specialty showroom outlets. We work with our retail partners on developing marketing and merchandising strategies to maximize their sales per square foot of shelf space. Through our Interflex and API Locksmiths businesses and Global Portable Security brands, we also provide products and services directly to end-users.

Our 10 largest customers represented approximately 24% of our total Net revenues in 2020. No single customer represented 10% or more of our total Net revenues in 2020.

Sales and Marketing

In markets where we sell through commercial and institutional distribution channels, we employ sales professionals around the world who work with a combination of end-users, security professionals, architects, contractors, engineers and distribution partners to develop specific, custom-configured solutions for our end-users’ needs. Our field sales professionals are assisted by specification writers who work with architects, engineers and consultants to help design door openings and security systems to meet end-users’ functional, aesthetic and regulatory requirements. Both groups are supported by dedicated customer care and technical sales-support specialists worldwide. We also support our sales efforts with a variety of marketing efforts, including trade-specific advertising, cooperative distributor merchandising, digital marketing and marketing at a variety of industry trade shows.

In markets in which we sell through retail and home-builder distribution channels, we have teams of sales, merchandising and marketing professionals who help drive brand and product awareness through our channel partners and to consumers. We utilize a variety of advertising and marketing strategies, including traditional consumer media, retail merchandising, digital marketing, retail promotions and builder and consumer trade shows, to support these teams.

We also work actively with several industry bodies around the world to help promote effective and consistent safety and security standards. For example, we are members of Builders Hardware Manufacturers Association (BHMA), Construction Specification Institute, Door and Hardware Institute (DHI), FiRa Consortium, Internet of Things Consortium (IoTC), Physical Security Interoperability Alliance (PSIA), Security Industry Association, Security Technology Alliance, ASSOFERMA (Italy), BHE (Germany) and UNIQ (France).

Production and Distribution

We manufacture our products in our geographic markets around the world. We operate 30 principal production and assembly facilities – 15 in Americas, 9 in EMEA and 6 in Asia Pacific. We own 16 of these facilities and lease the others. Our strategy is to produce in the region of use, wherever appropriate, to allow us to be closer to the end-user and increase efficiency and timely product delivery. Much of our U.S. based residential portfolio is manufactured in the Baja region of Mexico under the Maquiladora, Manufacturing and Export Services Industry ("IMMEX") program (formerly known as the maquiladora program). In managing our network of production and assembly facilities, we focus on continuous improvement in customer experience, employee health and safety, productivity, resource utilization and operational excellence.

We distribute our products through a broad network of channel partners. In addition, third-party manufacturing and logistics providers perform certain manufacturing, storage and distribution services for us to support certain parts of our manufacturing and distribution network.

Raw Materials

We support our region-of-use production strategy with corresponding region-of-use supplier partners, where available. Our global and regional commodity teams work with production leadership, product management and materials management teams to ensure adequate materials are available for production.

We purchase a wide range of raw materials, including steel, zinc, brass and other non-ferrous metals, to support our production facilities. Where appropriate, we may enter into fixed-cost contracts to lower overall costs.

Intellectual Property

Intellectual property, inclusive of certain patents, trademarks, copyrights, know-how, trade secrets and other proprietary rights, is important to our business. We create, protect and enforce our intellectual property investments in a variety of ways. We work actively in the U.S. and internationally to try to ensure the protection and enforcement of our intellectual property rights. We use trademarks on nearly all of our products and believe such distinctive marks are an important factor in creating a market for our goods, in identifying us and in distinguishing our products from others. We consider our CISA, Interflex, LCN, Schlage, SimonsVoss, Von Duprin and other associated trademarks to be among our most valuable assets, and we have registered these trademarks in a number of countries. Although certain proprietary intellectual property rights are important to our success, we do not believe we are materially dependent on any particular patent or license, or any particular group of patents or licenses.

Facilities

We operate through a broad network of sales offices, engineering centers, 30 principal production and assembly facilities and several distribution centers throughout the world. Our active properties represent approximately 6.3 million square feet, of which approximately 37% is leased. The following table shows the location of our principal worldwide production and assembly facilities:

Research and Development

We are committed to investing in our research and development capabilities with a focus on technology innovations that will deliver growth through the introduction of new products and solutions. In addition, we invest in initiatives that continuously drive improvements in product cost, quality, safety and sustainability.

Our research and development team is managed as a global, collaborative group to identify and develop new technologies and worldwide product platforms. We organize our resources regionally to leverage expertise in local standards and configurations for the benefit of our customers. Further, we operate a global technology center in Bangalore, India, which augments and supports the regional engineering teams.

Seasonality

Our business experiences seasonality that varies by product line. Because more construction and do-it-yourself projects occur during the second and third calendar quarters of each year in the Northern Hemisphere, our security product sales related to those projects are typically higher in those quarters than in the first and fourth calendar quarters. However, certain other businesses typically experience higher sales in the fourth calendar quarter due to project timing. In 2020, we experienced lower sales volumes during the second quarter, principally due to the economic challenges stemming from the COVID-19 pandemic, which were most pronounced during this quarter. This is not anticipated to be a long-term trend in the seasonality of our businesses. Net revenues by quarter for the years ended December 31, 2020, 2019 and 2018, were as follows:

	First Quarter	Second Quarter	Third Quarter	Fourth Quarter
2020	25%	21%	27%	27%
2019	23%	26%	26%	25%
2018	22%	26%	26%	26%

In addition, we maintain tobacco-free facilities and pursue strategies to incentivize healthy behaviors and outcome-driven rewards. Pay for performance strategies consider not only accomplishments, but how individuals achieve results. The Allegion Leadership Behaviors – be a pioneer, break boundaries, coach, champion change, be courageous and inspire – are used to identify key talent and to train and develop aspiring leaders. They also work in concert with our performance management system to reinforce our values and code of conduct in assessing how people lead and deliver top performance.

Talent Attraction

Talent attraction efforts begin well before people walk in our doors. Around the world, our sites partner with schools and support teachers, providing mentoring, grants, scholarships, internships, co-op programs, classroom technology and on-site activities. Our sites also sponsor science, technology, engineering and math ("STEM") programs and competitions such as robotics and engineering competitions. These programs expose students to careers in manufacturing and technology and provide educators with programming to encourage academic excellence and social development.

Key capabilities have been identified for our long-term corporate business strategy: talent, customer focus, innovation, partnering, pace and agility and collaboration. In recruiting for open positions, we participate in community job fairs and outreach to secondary schools, technical training programs, colleges and universities; promote open positions through internal and external recruiters, on websites and through social media; and encourage Company employees to refer talent.

Talent Development and Succession Planning

Talent development and succession planning at all levels of the organization are instrumental in ensuring we have the key capabilities to deliver the value proposition expected by our customers and employees. Inclusive succession planning is supported through the Allegion Leadership Behaviors, individual career mapping, assessment of performance and talent pipeline planning up to and including the Chief Executive Officer ("CEO"). On a quarterly basis, the executive team reviews talent development, focusing on developing a diverse succession bench, as part of their quarterly business review and a key component of the Allegion Operating System, our system of annual operation to support governance, reporting processes and management of the business. These cross-functional reviews highlight individuals who are ready for new opportunities, individuals who are on a special assignment or project and individuals early in their career that demonstrate emerging leadership skills.

Learning and Development

Opportunities for on-going learning and development are delivered to employees through structured coursework, on-site and expert-led training and experiential, applied development. The Allegion Academy is offered globally, supporting multiple languages and providing more than 17,000 self-guided online courses, as well as community channels on targeted skills and inclusion and diversity. We offer programs to provide successive levels of development, including reskilling and upskilling existing employees, as well as strengths-based leadership curriculum. Enterprise excellence initiatives and sprint teams expand skills in lean manufacturing and quality principles and lead to redesigning workflow to boost productivity and reduce waste.

Employee-led resource and affinity groups provide enrichment opportunities for women’s leadership, early-career professionals, creativity and innovation, health and fitness, community volunteering and philanthropy.

Engagement, Inclusion and Diversity

A commitment to engagement, inclusion and diversity is core to the Allegion Operating System. Engagement surveys provide team leaders with insights on potential areas of focus and help them prioritize and take action on their teams’ foundational, inclusion, growth and development needs. Strengths-based leadership is an element of our commitment to inclusion: the more employees understand their own strengths, the better equipped they are to add value and appreciate the contributions of diverse members of their teams.

Inclusion and diversity are topics for learning communities, employee roundtables and ongoing, regular analysis and dialogue among our people leaders, executive leadership and our Board of Directors. We believe in fundamental standards that support our employees, including a commitment to building and maintaining diverse and inclusive workplaces, safe and healthy practices and competitive wages and benefits. We embrace all differences and similarities among colleagues and within the relationships we foster with customers, suppliers and the communities where we live and work. Whatever background, experience, race, color, national origin, religion, age, gender, gender identity, disability status, sexual orientation, protected veteran status or any other characteristic protected by law, we make sure that potential and current employees have every opportunity for application and the opportunity to give their best at work because it’s the right thing to do.

We are dedicated to fulfilling equal opportunity commitments in all decisions regarding all employment actions and at all levels of employment. In partnership with the Company’s Human Resources organization, the Company’s Equal Employment Opportunity Officer ensures that the applicable policy and procedures are appropriately established, implemented and disseminated, including those prohibiting discrimination, harassment, bullying and/or retaliation.

Civic Involvement

Civic involvement is part of the value proposition we offer employees and supports inclusion, diversity, growth and development. The Company and its employees provide multi-faceted support for our communities, guided by three philanthropic pillars: safety and security; wellness; and addressing the unique needs of the communities where we work, live and thrive. Corporate sponsorships and voluntary employee payroll deductions support a wide range of non-profits, including those that address housing and school security and safety; children and youth programs; education and scholarships for people of color and those who are economically disadvantaged and support for Historically Black Colleges and Universities; community safety nets for basic needs (e.g., food, shelter, transportation) for underserved people and to break the cycle of poverty; wellness, mental health, health research, emergency relief and blood supply initiatives; and programs to advance equality, justice and address systemic bias. In addition to corporate sponsorships, site leaders and employees are encouraged to organize local volunteer and fundraising activities, provide grants to local organizations and serve on boards and committees. Recognizing the growing number of people facing food insecurity in the wake of the COVID-19 pandemic, we supplemented on-going food drives at local sites with a one-time $500,000 gift to support communities in need in the fourth quarter of 2020.

Respect for Human Rights

Our respect for human rights is expressed in standards for our employees, our business partners, our customers and our communities. We have adopted and continue to uphold our Global Human Rights Policy, with standards that align with basic working conditions and human rights concepts advanced by international organizations such as the International Labor Organization and the United Nations. This policy also represents our own minimum standards for working conditions and human rights in our business and supply chains. In addition, we conduct risk assessments and continue to have conversations with the suppliers and companies we work with about the importance of human rights.

Employee Health and Safety

Employee health and safety are top priorities, and we consistently rank as the safest among leading competitors on core measures such as the total recordable incident rate. ‘Be safe, be healthy’ is a core organizational value in our proactive safety culture and has guided our response to the COVID-19 pandemic throughout 2020. We have adopted numerous health and safety measures in accordance with best-practice safe hygiene guidelines issued by recognized health experts like the U.S. Centers for Disease Control and Prevention (“CDC”), the European Centre for Disease Prevention and Control (“ECDC”) and the World Health Organization (“WHO”), as well as any applicable government mandates. These health and safety measures include, but are not limited to:

13

Table of Contents

•Work-from-home arrangements for employees, where possible;

•Continuous safe hygiene education in accordance with evolving guidelines;

•Regular communication updates to leadership and team members;

•Aggressive and regular deep cleaning and disinfecting schedules;

•Social distancing measures, such as signage and physical barriers or reconfigurations of workspaces;

•Reduced density measures, such as staggering work shifts and breaks;

•Mask use requirements and expectations at our facilities;

•Temperature and health screenings prior to entering facilities;

•Increased available supplies for employees, like masks, cleaning solutions, hand sanitizers, thermometers and gloves; and

•Temporary travel, visitor and in-person meeting restrictions.

Senior executives and the CEO have responsibility for risk management, employee accountability and safety hazard recognition and take a personal responsibility toward executing on safety initiatives. The Company monitors leading and lagging indicators related to health and safety as part of its ongoing management of the Allegion Operating System and regularly updates the Corporate Governance and Nominating Committee of the Board of Directors on key accomplishments and employee health and safety topics.

Regulatory Matters

We are subject to a variety of federal, state and local laws and regulations, both within and outside the U.S., relating to environmental, health and safety concerns. We are committed to conducting our business in a safe, environmentally responsible and sustainable manner, in compliance with all applicable environmental, health and safety laws and regulations, and in a manner that helps promote and protect the health and safety of our environment, associates, customers, contractors and members of our local communities worldwide. We operate with principles that support our proactive commitments, including:

•Integrating sound, environmental, health, safety (EHS) and sustainability strategies in all elements of our business functions, including objectives and measurements;

•Conducting periodic, formal evaluation of our compliance status and annual review of objectives and targets;

•Creating a workplace culture where all employees are responsible for safety;

•Making continuous improvements in EHS and sustainability management systems and performance, including the reduction in the usage of natural resources, waste minimization, prevention of pollution and prevention of workplace accidents, injuries and risks;

•Designing, operating and maintaining our facilities in a manner that minimizes negative EHS and sustainability impacts;

•Using materials responsibly, including, where feasible, the recycling and reuse of materials; and

•Acting in a way that shows sensitivity to community concerns about EHS and sustainability issues.

We recognize that these principles are critical to our future success. We have a dedicated environmental program designed to reduce the utilization and generation of hazardous materials during the manufacturing process and to remediate any identified environmental concerns. As to the latter, we are currently engaged in site investigations and remediation activities to address environmental cleanup from past operations at current and former production facilities. We also regularly evaluate our remediation methods that are in addition to, or in replacement of, those we currently utilize based upon enhanced technology and regulatory changes. We are sometimes a party to environmental lawsuits and claims and have, from time to time, received notices of potential violations of environmental laws and regulations from the U.S. Environmental Protection Agency (the "EPA") and similar state authorities. We have also been identified as a potentially responsible party ("PRP") for cleanup costs associated with off-site waste disposal at federal Superfund and state remediation sites. For all such sites, there are other PRPs and, in most instances, our involvement is minimal.

In estimating our liability, we have assumed that we will not bear the entire cost of remediation of any site to the exclusion of other PRPs who may be jointly and severally liable. The ability of other PRPs to participate has been taken into account, based on our understanding of the parties’ financial condition and probable contributions on a per site basis. Additional lawsuits and claims involving environmental matters are likely to arise from time to time in the future. For a further discussion of our potential environmental liabilities, see Note 21 to the Consolidated Financial Statements.

Item 1A. RISK FACTORS

We discuss our expectations regarding future performance, events and outcomes in this Form 10-K, quarterly and annual reports, press releases and other written and oral communications. All statements except for historical and present factual information are “forward-looking statements” and are based on financial data and business plans available only as of the time the statements are made, which may become outdated or incomplete. Forward-looking statements are inherently uncertain, and investors must recognize that events could significantly differ from our expectations. You should carefully consider the risk factors discussed below, together with all the other information included in this Form 10-K, in evaluating us, our ordinary shares and our senior notes. If any of the risks below actually occurs, our business, financial condition, results of operations and cash flows could be materially and adversely affected. Any such adverse effect may cause the trading price of our ordinary shares to decline, and as a result, you could lose all or part of your investment in us. Our business may also be adversely affected by risks and uncertainties not known to us or risks that we currently believe to be immaterial. We assume no obligation to update any forward-looking statements as a result of new information, future events or other factors.

Strategic and Operational Risks

Our normal business operations have been, and are expected to continue to be, adversely impacted by the global COVID-19 pandemic.

The COVID-19 outbreak, which was declared by the WHO as a pandemic in March 2020, and preventative measures taken to contain or mitigate this pandemic have caused, and are continuing to cause, business slowdowns or shutdowns in various regions around the world. This pandemic has also caused, and may continue to cause, disruption to our global supply chain and business operations, in addition to the various effects noted elsewhere within the risk factors contained in this Annual Report on Form 10-K. Actions taken to help limit the spread of COVID-19, such as general public health decrees or other government mandates to restrict business activities and travel, avoid large gatherings or to self-quarantine, have impacted and will likely continue to impact our ability to carry out business as usual, including the temporary suspension of some of our operations, shortages in materials, reduction in customer demand, increased absenteeism, costs associated with operational changes and an extended period of remote work arrangements for some of our employees which could increase cybersecurity risks and other operational risks. Conversely, as governments ease their restrictions and social interactions increase prior to the development and distribution of an effective vaccine or treatments for COVID-19, preventative and precautionary measures may not be sufficient to mitigate the risk of increased infection and could result in increased illness among our employees, business partners and others, and lead to further business interruption. In addition, a significant number of our customers, suppliers, vendors and other business partners have been adversely affected by the COVID-19 pandemic. While we cannot predict the impact that this pandemic will continue to have on our customers, suppliers, vendors and other business partners and each of their financial conditions, any material adverse effects on these parties could adversely impact us.

The global economic uncertainty due to this pandemic has also negatively impacted, and may continue to adversely affect, our results of operations and financial condition. For example, this pandemic has led to changes in commercial real estate occupancy, increases in work-from-home arrangements, constraints on government and institutional budgets and an uncertain business climate, which have all contributed to declines and delays in new construction and renovation activity during 2020, including in many of the commercial and institutional construction markets we serve. These challenges may be significant and continue beyond the COVID-19 pandemic, and the rate and sustainability of future growth remains uncertain, as the long-term impacts of the pandemic and related market disruption are not yet known.

Additionally, as a result of the global economic disruption and uncertainty due to the COVID-19 pandemic, interim impairment tests were performed on select goodwill and indefinite-lived trade name assets in the first quarter of 2020, resulting in impairment charges of approximately $96.3 million. If the on-going economic impact of the COVID-19 pandemic proves to be more severe than estimated, the economic recovery takes longer to materialize or does not materialize as strongly as anticipated, this could result in further impairment charges in the future.

Despite our efforts to manage and mitigate these impacts to the Company, their ultimate impact also depends on factors beyond our knowledge or control, including the duration and severity of this pandemic, third-party actions taken to contain its spread and mitigate its public health effects, the development, distribution and acceptance of an effective vaccine and the pace of global economic recovery following containment of the spread. The impact of the COVID-19 pandemic continues to evolve, and its ultimate impact on our business is highly uncertain and difficult to predict. The continued spread of COVID-19 may have further adverse impacts on our business, operations, customer demand, supply chain, cash flow generation, financial position and liquidity and may also exacerbate other risks and uncertainties described in this Annual Report on Form 10-K. Further, our management is focused on mitigating the impacts of COVID-19 which has required, and will continue to require, a large investment of time and resources, which may divert attention and resources from other business matters.

Increased competition, including from technological developments, could adversely affect our business.

The markets in which we operate include a large number of participants, including multi-national, regional and small, local companies. We primarily compete on the basis of quality, innovation, expertise, effective channels to market, breadth of product offering and price. We may be unable to effectively compete on all these bases. Further, in a number of our product offerings, we compete with our retail customers and technology partners who use their own private labels. If we are unable to anticipate evolving trends in the market or the timing and scale of our competitors’ activities and initiatives, including increased competition from private label brands, the demand for our products and services could be negatively impacted.

In addition, we compete in an industry that is experiencing the convergence of mechanical, electronic and digital products. Technology and innovation play significant roles in the competitive landscape. Our success depends, in part, upon the research, development and implementation of new technologies and products including obtaining, maintaining and enforcing necessary intellectual property protections. Securing and maintaining key partnerships and alliances, recruiting and retaining highly skilled and qualified employee talent and having access to technologies, services, intellectual property and solutions developed by others will play a significant role in our ability to effectively compete. The continual development of new technologies by existing and new competitors, including non-traditional competitors with significant resources, could adversely affect our ability to sustain operating margins and desirable levels of sales volumes. To remain competitive, we must develop new products and respond to new technologies in a timely manner.

Our growth is dependent, in part, on the development, commercialization and acceptance of new products and services.

We must develop and commercialize new products and services that meet the varied and evolving needs of our customers and end-users in order to remain competitive in our current and future markets and in order to continue to grow our business. The speed of development by our competitors and new market entrants is increasing. We cannot provide any assurance that any new product or service will be successfully commercialized in a timely manner, if ever, or, if commercialized, will result in returns greater than our investment. Investment in a product or service could divert our attention and resources from other projects that become more commercially viable in the market. We also cannot provide any assurance that any new product or service will be accepted by the market.

Changes in customer and consumer preferences and the inability to maintain beneficial relationships with large customers could adversely affect our business.

We have significant customers, particularly major retailers, although no one customer represented 10% or more of our total Net revenues in any of the past three fiscal years. The loss or material reduction of business, the lack of success of sales initiatives or changes in customer preferences or loyalties for our products related to any such significant customer could have a material adverse impact on our business. In addition, major customers who are volume purchasers are much larger than us and have strong bargaining power with suppliers. This limits our ability to recover cost increases through higher selling prices. Furthermore, unanticipated inventory adjustments by these customers can have a negative impact on sales.

We also sell our products through various trade channels, including traditional retail and e-commerce channels. If we or our major customers are not successful in navigating the shifting consumer preferences to distribution channels such as e-commerce, our expected future revenues may be negatively impacted.

If our products or solutions fail to meet certification and specification requirements, are defective, or otherwise fall short of end-users' needs and expectations, our business may be negatively impacted.

The security and access control product markets we serve often have unique certification and specification requirements, reflecting local regulatory requirements and highly variable end-user needs. While we strive to meet all certification and specification requirements, if any of our products or solutions do not meet such requirements, or contain, or are perceived to contain, defects or otherwise fall short of end-users' needs and expectations, we may incur significant costs and our business, results of operations or financial condition may be negatively impacted.

Additionally, as end-users have continued to adopt newer technologies in their facilities and homes, accelerated by the increasing adoption of IoT technologies, growth in sales of electronic security products and solutions are expected to outperform growth in sales of mechanical security products. Electronic security products and solutions are increasingly more sophisticated and technologically complex than the mechanical security products we sell, and have an increased risk of design or manufacturing defects, which could lead to product liability claims, recalls, product replacements or modifications, write-offs

of inventory or other assets and significant warranty and other expenses. Product quality issues can also adversely affect the end-user experience, resulting in reputational harm, loss of competitive advantage, poor market acceptance, reduced demand for products and solutions, delay in new product and service introductions and lost sales. Further, adverse publicity, whether or not justified, or allegations of product or service quality issues, even if false or unfounded, could damage our reputation and negatively affect our sales.

Our business and innovation strategies include making acquisitions of, and investments in, external companies. These acquisitions and investments could be unsuccessful or consume significant resources, which could adversely affect our operating and financial results.

We will continue to analyze and evaluate the acquisition of strategic businesses or product lines with the potential to strengthen our industry position or enhance our existing set of products and services offerings. We cannot provide assurance that we will identify or successfully complete acquisitions with suitable candidates in the future, nor can we provide assurance that completed acquisitions will be successful, including efficient integration and creation of synergies.

Some of the businesses we may seek to acquire may be marginally profitable or unprofitable. For these businesses to achieve acceptable levels of profitability, we must improve their management, operations, products and market penetration. We may not be successful in this regard, and we may encounter other difficulties in integrating acquired businesses into our existing operations.

Acquisitions may involve significant cash expenditures, debt incurrence, operating losses and expenses. Acquisitions also involve numerous other risks, including:

•Diversion of management's time and attention from daily operations;

•Difficulties integrating acquired businesses, technologies and personnel into our business;

•Difficulties completing the transaction in a timely manner;

•Difficulties realizing synergies expected to result from acquisitions;

•Difficulties in obtaining and verifying the financial statements and other business information of acquired businesses;

•Inability to obtain regulatory approvals and/or required financing on favorable terms;

•Potential loss of key employees, key contractual relationships or key customers of acquired companies or of us;

•Difficulties competing in the new markets we enter;

•Assumption of the liabilities and exposure to unforeseen liabilities of acquired companies;

•Dilution of interests of holders of our ordinary shares through the issuance of equity securities or equity-linked securities; and

•Difficulty in integrating financial reporting systems and implementing controls, procedures and policies, including disclosure controls and procedures and internal control over financial reporting, appropriate for public companies of our size at companies that, prior to the acquisition, had lacked such controls, procedures and policies.

Further, as part of our innovation strategy, from time to time we invest in start-up companies and/or development stage technology or other companies. In evaluating these opportunities, we follow a structured evaluation process that considers factors such as potential financial returns, new expertise in emerging technology and business benefits. Despite our best efforts to calculate potential return and risk, some or all of these companies we invest in may be unprofitable at the time of, and subsequent to, our investment. We may lose money in these investments, including the potential for future impairment charges on the investments, and the anticipated benefits of the technology and business relationships may be less than expected.

We continually look to expand our services and products into new international markets, and as we do, we will have only limited experience in marketing and operating services and products in such markets. In some instances, we may rely on the efforts and abilities of third-party and foreign business partners in such markets. Certain international markets may be slower than our established markets in adopting our services and products, and our operations in such markets may not develop at a rate that supports our level of investment. In addition to the risks outlined above, expansion into certain new markets may require us to compete with local businesses with greater knowledge of the market, including the tastes and preferences of end-users and businesses with dominant market shares. Any acquisitions or investments may ultimately not be successful, may harm our business or financial condition and/or result in impairment charges.

We may pursue business opportunities that diverge from our core business.

We may pursue business opportunities that diverge from our core business, including expanding our products or service offerings, investing in new and unproven technologies and forming new alliances with companies to distribute our products and services. We can offer no assurance that any such business opportunities will prove successful. Among other negative effects,

18

Table of Contents

our investment in new business opportunities may exceed the returns we realize. Additionally, any new investments could have higher cost structures than our current business, which could reduce operating margins and require more working capital. In the event that working capital requirements exceed operating cash flow, we may be required to draw on our revolving credit facility or pursue other external financing, which may not be readily available.

Our enterprise excellence efforts may not achieve the improvements we expect.

We utilize a number of tools to improve efficiency and productivity. Implementation of new processes to our operations could cause disruptions and may prove to be more difficult, costly or time consuming than expected. There is no assurance that all of our planned enterprise excellence projects will be fully implemented, or if implemented, will realize the expected improvements.

We may not be able to effectively manage and implement restructuring initiatives or other organizational changes.

We have, from time to time, restructured or made other adjustments to our workforce and manufacturing footprint in response to market or product changes, performance issues, changes in strategy, acquisitions and/or other internal and external considerations. For example, we recently announced that effective January 1, 2021, our EMEA and Asia Pacific operating segments would be combined to form the new Allegion International segment. These restructuring activities and other organizational changes often result in increased restructuring costs, diversion of management’s time and attention from daily operations and temporarily reduced productivity. If we are unable to successfully manage and implement these and other organizational changes, we may not achieve or sustain the expected growth or cost savings benefits of these activities or do so within the expected timeframe. These effects could recur in connection with future acquisitions and other organizational changes and our Net revenues and other results of operations could be negatively affected.

Disruptions in our global supply chain, including product manufacturing and logistical services provided by supplier partners, may negatively impact our business.

Our ability to meet our customers' needs and achieve cost targets depends on our ability to maintain key manufacturing and supply arrangements, including execution of supply chain optimizations and certain sole supplier or sole manufacturing arrangements. The loss or disruption of such manufacturing and supply arrangements could interrupt product supply and, if not effectively managed and remedied, have an adverse impact on our business.

We procure certain products, components and logistical services from supplier partners located throughout the world. Our reliance on these third parties reduces our control over the manufacturing and delivery process, exposing us to risks including reduced control over quality assurance, product costs, product supply and delivery delays. If we are unable to effectively manage these relationships, or if these third parties experience delays, disruptions, capacity constraints, regulatory issues or quality control problems in their operations or otherwise fail to meet our future requirements for timely delivery, our ability to ship and deliver certain of our products to our customers could be impaired and our business could be harmed.

The effects of global climate change or other unexpected events, including global health crises, may disrupt our operations and have a negative impact on our business.

The effects of global climate change, such as extreme weather conditions and natural disasters occurring more frequently or with more intense effects, or the occurrence of unexpected events including wildfires, tornadoes, hurricanes, earthquakes, floods, tsunamis and other severe hazards or global health crises, such as the outbreak of Ebola or the global COVID-19 pandemic, or other actual or threatened epidemic, pandemic, outbreak and spread of a communicable disease or virus, in the countries where we operate or sell products and provide services, could adversely affect our operations and financial performance. Extreme weather, natural disasters, power outages, global health crises or other unexpected events could disrupt our operations by impacting the availability and cost of materials needed for manufacturing, causing physical damage and partial or complete closure of our manufacturing sites or distribution centers, loss of human capital, temporary or long-term disruption in the manufacturing and supply of products and services and disruption in our ability to deliver products and services to customers. These events and disruptions could also adversely affect our customers’ and suppliers’ financial condition or ability to operate, resulting in reduced customer demand, delays in payments received or supply chain disruptions. Further, these events and disruptions could increase insurance and other operating costs, including impacting our decisions regarding construction of new facilities to select areas less prone to climate change risks and natural disasters, which could result in indirect financial risks passed through the supply chain or other price modifications to our products and services.

In particular, the ultimate extent of the impact of any epidemic, pandemic or other global health crisis on our business, financial condition and results of operations will depend on future developments which are highly uncertain and cannot be predicted,

19

Table of Contents

including new information that may emerge concerning the duration and severity of such epidemic, pandemic or other global health crisis, actions taken to contain or prevent their further spread and the pace of global economic recovery following containment of the spread.

We may be subject to risks relating to our information technology and operational technology systems.

We rely extensively on information technology and operational technology systems, networks and services including hardware, software, firmware and technological applications and platforms (collectively, "IT Systems") to manage and operate our business from end-to-end, including ordering and managing materials from suppliers, design and development, manufacturing, marketing, selling and shipping to customers, invoicing and billing, managing our banking and cash liquidity systems, managing our enterprise resource planning and other accounting and financial systems and complying with regulatory, legal and tax requirements. There can be no assurance that our current IT Systems will function properly. We have invested and will continue to invest in improving our IT Systems. Some of these investments are significant and impact many important operational processes and procedures. There is no assurance that any newly implemented IT Systems will improve our current systems, improve our operations or yield the expected returns on the investments. In addition, the implementation of new IT Systems may cause disruptions in our operations and, if not properly implemented and maintained, negatively impact our business. If our IT Systems cease to function properly or if these systems do not provide the anticipated benefits, our ability to manage our operations could be impaired.

We currently rely on third-party vendors for many of the critical elements of our global information and operational technology infrastructure and their failure to provide effective support for such infrastructure could negatively impact our business and financial results.

We have outsourced many of the critical elements of our global information and operational technology infrastructure to third-party service providers in order to achieve efficiencies. If such service providers do not perform or do not perform effectively, we may not be able to achieve the expected efficiencies and may have to incur additional costs to address failures in providing service by the service providers. Depending on the function involved, such non-performance, ineffective performance or failures of service may lead to business disruptions, processing inefficiencies or security breaches.

Disruptions or breaches of our information systems could adversely affect us.

Despite our implementation of cybersecurity measures which have focused on prevention, mitigation, resilience and recovery, our network and products, including access solutions, may be vulnerable to cybersecurity attacks, computer viruses, malicious codes, malware, ransomware, phishing, social engineering, denial of service, hacking, break-ins and similar disruptions. Cybersecurity attacks and intrusion efforts are continuous and evolving, and in certain cases they have been successful at the most robust institutions. The scope and severity of risks that cyber threats present have increased dramatically and include, but are not limited to, malicious software, attempts to gain unauthorized access to data or premises, exploiting weaknesses related to vendors or other third parties that could be exploited to attack our systems, denials of service and other electronic security breaches that could lead to disruptions in systems, unauthorized release of confidential or otherwise protected information and corruption of data. Any such event could have a material adverse effect on our business, operating results and financial condition, as we face regulatory, reputational and litigation risks resulting from potential cyber incidents, as well as the potential of incurring significant remediation costs.

Our daily business operations also require us to collect and/or retain sensitive data such as intellectual property, proprietary business information and data related to customers, employees, suppliers and business partners within our networking infrastructure including data from individuals subject to the European Union's General Data Protection Regulation, that is subject to privacy and security laws, regulations and/or customer-imposed controls. Despite our efforts to protect such data, the loss or breach of such data due to various causes including material security breaches, catastrophic events, extreme weather, natural disasters, power outages, system failures, computer viruses, improper data handling, programming errors, unauthorized access and employee error or malfeasance could result in wide reaching negative impacts to our business, and as such, the ongoing maintenance and security of this information is pertinent to the success of our business operations and our strategic goals.

In addition, we operate in an environment where there are different and potentially conflicting data privacy laws and regulations in effect or expected to go into effect in the future, including regulations related to devices connected through IoT, in the various jurisdictions in which we operate, and we must understand and comply with such laws and regulations while ensuring our data is secure.

20

Table of Contents

Our networking infrastructure and related assets may be subject to unauthorized access by hackers, employee error or malfeasance or other unforeseen activities. Such issues could result in the disruption of business processes, network degradation and system downtime, along with the potential that a third party will exploit our critical assets such as intellectual property, proprietary business information and data related to our customers, suppliers and business partners. To the extent that such disruptions occur and our business continuity plans do not effectively address these disruptions in a timely manner, they may cause delays in the manufacture or shipment of our products and the cancellation of customer orders and, as a result, our business operating results and financial condition could be materially and adversely affected, resulting in a possible loss of business or brand reputation.

Our ability to successfully grow and expand our business depends on our ability to recruit and retain a highly qualified and diverse workforce.

Our ability to successfully grow and expand our business depends on the contributions and abilities of our employees and key management, including, for example, the ability of our sales force to adapt to any changes made in the sales organization and achieve adequate customer coverage. We must therefore continue to effectively recruit, retain and motivate key management, sales and other highly qualified, skilled and diverse personnel to maintain our current business and support our projected growth. A shortage of these key employees for various reasons, including changes in laws and policies regarding immigration and work authorizations in jurisdictions where we have operations, might jeopardize our ability to grow and expand our business.

Economic, Market and Financial Risks

Our global operations subject us to economic risks.

We are incorporated in Ireland and operate in countries worldwide. Our global operations depend on products manufactured, purchased and sold in the U.S. and internationally, including in Australia, Canada, China, Europe, Korea, Mexico, New Zealand and the Middle East. The political, economic and regulatory environments in which we operate are becoming increasingly volatile and uncertain. Accordingly, we are subject to risks that are inherent in operating globally, including:

•Changes to trade agreements, sanctions, import and export regulations, including imposition of burdensome tariffs and quotas, and customs duties;

•Changes in applicable tax regulations and interpretations;

•Economic downturns and social and political instability;

•Changes in laws and regulations or imposition of currency restrictions and other restraints in various jurisdictions;

•Limitation of ownership rights, including expropriation of assets by a local government, and limitation on the ability to repatriate earnings;

•Sovereign debt crises and currency instability in developed and developing countries;

•Difficulty in staffing and managing global operations;

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

•Political unrest, national and international conflict, including war, border closures, civil disturbances and terrorist acts.

These risks could increase our cost of doing business in the U.S. and internationally, increase our counterparty risk, disrupt our operations, disrupt the ability of suppliers and customers to fulfill their obligations, increase our effective tax rate, increase the cost of our products, limit our ability to sell products in certain markets, reduce our operating margin, reduce cash flow and negatively impact our ability to compete.

Our business relies on the institutional, commercial and residential construction and remodeling markets.

Demand for our security products and solutions relies on the institutional, commercial and residential construction and remodeling markets, which are marked by cyclicality based on overall economic conditions, including consumer confidence and disposable income, corporate and government spending, work-from-home trends, availability of credit and demand for new housing and infrastructure. Weakness or instability in one or more of these markets may cause current and potential customers to delay or cancel major capital projects, or otherwise choose not to make purchases, which could negatively impact the demand for our products and solutions and erode average selling prices.

Currency exchange rate fluctuations may adversely affect our results.

We are exposed to a variety of market risks, including the effects of changes in currency exchange rates. See "Management’s Discussion and Analysis of Financial Condition and Results of Operations - Quantitative and Qualitative Disclosure About Market Risk."

Approximately 30% of our 2020 Net revenues were derived outside the U.S., and we expect sales to non-U.S. customers to continue to represent a significant portion of our consolidated Net revenues. Although we may enter into currency exchange contracts to reduce our risk related to currency exchange fluctuations, changes in the relative fair values of currencies occur from time to time and may, in some instances, have a material impact on our results of operations. We do not hedge against all of our currency exposure and therefore, our business will continue to be susceptible to currency fluctuations.

We also translate assets, liabilities, revenues and expenses denominated in non-U.S. dollar currencies into U.S. dollars for our Consolidated Financial Statements based on applicable exchange rates. Consequently, fluctuations in the value of the U.S. dollar compared to other currencies may have a material impact on the value of these items in our Consolidated Financial Statements, even if their value has not changed in their original currency.

Commodity shortages, price increases and higher energy prices could negatively affect our financial results.

We rely on suppliers to secure commodities, including steel, zinc, brass and other non-ferrous metals, required for the manufacture of our products. A disruption of deliveries from our suppliers or decreased availability of commodities could have an adverse effect on our ability to meet our commitments to customers or increase our operating costs. We believe that available sources of supply will generally be sufficient for our needs for the foreseeable future. Nonetheless, the unavailability of some commodities could have a material adverse impact on our business.

Volatility in the prices of these commodities could increase the costs of our products and services, and we may not be able to pass on these costs to our customers. We do not currently use financial derivatives to hedge against this volatility; however, we utilize firm purchase commitments to mitigate risk. The pricing of some commodities we use is based on market prices. To mitigate this exposure, we may use annual price contracts to minimize the impact of inflation and to benefit from deflation.

Additionally, we are exposed to fluctuations in energy prices due to the instability of current market prices. Higher energy costs increase our operating costs and the cost of shipping our products and supplying services to our customers around the world. Consequently, sharp price increases, the imposition of taxes or an interruption of supply could cause us to lose the ability to effectively manage the risk of rising energy prices and may have an adverse impact on our results of operations and cash flows.

We may be required to recognize impairment charges for our goodwill, indefinite-lived intangible assets and other long-lived assets.

At December 31, 2020, the net carrying value of our goodwill and other indefinite-lived intangible assets totaled approximately $819.0 million and $118.3 million, respectively. Pursuant to U.S. generally accepted accounting principles ("GAAP"), we are required to annually assess our goodwill and indefinite-lived intangible assets for impairment. In addition, interim assessments must be performed for these and other long-lived assets whenever events or changes in circumstances indicate that an impairment may have occurred. Significant disruptions to our business or end market conditions, protracted economic weakness, unexpected significant declines in operating results of reporting units, divestitures or market capitalization declines may result in recognition of impairment charges to our goodwill, indefinite-lived intangible or other long-lived assets. Specifically, an unanticipated deterioration in Net revenues and/or operating margins generated by our newly created Allegion International segment could trigger future impairments. Any charges relating to such impairments could have a material adverse impact on our results of operations in the periods when recognized.

The capital and credit markets are important to our business.

Instability in U.S. and global capital and credit markets, including market disruptions, limited liquidity and interest rate volatility or reductions in the credit ratings assigned to us by independent ratings agencies, could reduce our access to capital markets or increase the cost of funding our short and long-term credit requirements. In particular, if we are unable to access capital and credit markets on terms that are acceptable to us, we may not be able to make certain investments or fully execute our business plans and strategy.

Our suppliers and customers are also dependent upon the capital and credit markets. Limitations on the ability of customers, suppliers or financial counterparties to access credit could lead to insolvencies of key suppliers and customers, limit or prevent

22

Table of Contents

customers from obtaining credit to finance purchases of our products and services and cause delays in the delivery of key products from suppliers.

There are risks associated with our outstanding and future indebtedness.

We have approximately $1.4 billion of outstanding indebtedness at December 31, 2020. In addition, we have a senior unsecured revolving credit facility (the "Revolving Facility") that permits borrowings of up to an additional $500 million. Volatility in the credit markets could adversely impact our ability to obtain favorable financing terms in the future. A portion of our cash flows from operations is dedicated to servicing our indebtedness and will not be available for other purposes, including our operations, capital expenditures, payment of dividends, share repurchases or future business opportunities.

Our ability to make scheduled payments or to refinance our debt obligations depends on our financial and operating performance, which is subject to prevailing economic and competitive conditions and to certain financial, business and other factors beyond our control. If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay capital expenditures, reduce or eliminate the payment of dividends, sell assets, seek additional capital or seek to restructure or refinance our indebtedness. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations. In such event, we could face substantial liquidity problems and might be required to sell material assets or operations to attempt to meet our debt service and other obligations.

Additionally, at December 31, 2020, our borrowings included a variable rate term loan facility indexed to LIBOR (the "Term Facility", and together with the Revolving Facility, the "Credit Facilities") with an outstanding balance of $238.8 million, which exposes us to variable interest rate risk. We are also exposed to the risk of rising interest rates to the extent that we fund our operations with short-term or variable-rate borrowings under our Revolving Facility. If LIBOR or other applicable base rates under our Credit Facilities increase in the future, our Interest expense could increase. Additionally, the regulator that oversees LIBOR has announced that it cannot guarantee LIBOR's availability after 2021. In the event LIBOR is discontinued, replaced, significantly changed or ceases to be recognized as an acceptable benchmark, there may be uncertainty or differences in the calculation of our applicable interest rate or required payment amounts for our Credit Facilities. This could also require different hedging strategies and require renegotiation of our existing Credit Facilities. While we do not currently anticipate the transition from LIBOR and the risks thereto to have a material adverse effect on us, it remains uncertain at this time.

Legal and Compliance Risks

We are subject to risks related to corporate social responsibility and reputational matters.

Our reputation and the reputation of our brands, including the perception held by our customers, end-users, business partners, investors, other key stakeholders and the communities in which we do business are influenced by various factors. There is an increased focus from our stakeholders on environmental, social and governance ("ESG") practices and disclosure – and if we fail, or are perceived to have failed, in any number of ESG matters, such as environmental stewardship, inclusion and diversity, workplace conduct and support for local communities, our reputation or the reputation of our brands may suffer. Such damage to our reputation and the reputation of our brands may negatively impact our business, financial condition and results of operations.

In addition, negative or inaccurate postings or comments on social media or networking websites about the Company or our brands could generate adverse publicity that could damage our reputation or the reputation of our brands. If we are unable to effectively manage real or perceived issues, including concerns about product quality, safety, corporate social responsibility or other matters, sentiments toward the Company or our products could be negatively impacted, and our financial results could suffer.

Our brands are important assets of our businesses, and violation of our trademark rights by imitators could negatively impact revenues and brand reputation.

Our brands and trademarks enjoy a reputation for quality and value and are important to our success and competitive position. Unauthorized use of our trademarks may not only erode sales of our products but may also cause significant damage to our brand name and reputation, interfere with relationships with our customers and increase litigation costs. There can be no assurance that our on-going effort to protect our brand and trademark rights will prevent all violations.

Material adverse legal judgments, fines, penalties or settlements could adversely affect our business.

We are currently and may in the future become involved in legal proceedings and disputes incidental to the operation of our business. Our business may be adversely affected by the outcome of these proceedings and other contingencies (including, without limitation, environmental, product liability, antitrust, intellectual property, data protection, privacy and labor and employment matters) that cannot be predicted with certainty. As required by GAAP, we establish reserves based on our assessment of contingencies. Subsequent developments in legal proceedings and other contingencies may affect our assessment and estimates of the loss contingency recorded as a reserve, and we may be required to make additional material payments.

Allegations that we have infringed the intellectual property rights of third parties could negatively affect us.

We may be subject to claims of infringement of intellectual property rights by third parties. In particular, we often compete in areas having extensive intellectual property rights owned by others and we have become subject to claims alleging infringement of intellectual property rights of others. In general, if it is determined that one or more of our technologies, products or services infringes the intellectual property rights owned by others, we may be required to cease marketing those products or services, to obtain licenses from the holders of the intellectual property at a material cost or to take other actions to avoid infringing such intellectual property rights. The litigation process is costly and subject to inherent uncertainties, and we may not prevail in litigation matters regardless of the merits of our position. Adverse intellectual property litigation or claims of infringement against us may become extremely disruptive if the plaintiffs succeed in blocking the trade of our products and services and may have a material adverse effect on our business.

Our reputation, ability to do business and results of operations could be impaired by adverse publicity or improper conduct by any of our employees, agents or business partners.

We are subject to regulation under a variety of U.S. federal and state and non-U.S. laws, regulations and policies including laws related to anti-corruption, export and import compliance, anti-trust and money laundering due to our global operations. We cannot provide assurance that our internal controls will always protect us from the improper conduct of our employees, agents and business partners. Any improper conduct could damage our reputation and subject us to, among other things, civil and criminal penalties, material fines, equitable remedies (including profit disgorgement and injunctions on future conduct), securities litigation and a general loss of investor confidence.

Our operations are subject to regulatory risks.

Our U.S. and non-U.S. operations are subject to a number of laws and regulations, including fire and building codes and environmental, health and safety standards. We have incurred, and will be required to continue to incur, significant expenditures to comply with these laws and regulations. Changes to, or changes in interpretations of, current laws and regulations could require us to increase our compliance expenditures, cause us to significantly alter or discontinue offering existing products and services or cause us to develop new products and services. Altering current products and services or developing new products and services to comply with changes in the applicable laws and regulations could require significant research and development investments, increase the cost of providing the products and services and adversely affect the demand for our products and services.

In the event a regulatory authority concludes that we are not or have not at all times been in full compliance with these laws or regulations, we could be fined, criminally charged or otherwise sanctioned.

Certain environmental laws assess liability on current or previous owners of real property or operators of manufacturing facilities for the costs of investigation, removal or remediation of hazardous substances or materials at such properties or at properties at which parties have disposed of hazardous substances. Liability for investigative, removal and remedial costs under certain U.S. federal and state laws and certain non-U.S. laws are retroactive, strict and joint and several. In addition to cleanup actions brought by governmental authorities, private parties could bring personal injury or other claims due to the presence of, or exposure to, hazardous substances. We have received notification from U.S. and non-U.S. governmental agencies, including the EPA and similar state environmental agencies, that conditions at a number of current and formerly owned sites where we and others have disposed of hazardous substances require investigation, cleanup and other possible remedial action. These agencies may require that we reimburse the government for its costs incurred at these sites or otherwise pay for the costs of investigation and cleanup of these sites, including by providing compensation for natural resource damage claims from such sites. For more information, see "Item 1. Business - Regulatory Matters."

While we have planned for future capital and operating expenditures to maintain compliance with environmental laws and have accrued for costs related to current remedial efforts, our costs of compliance, or our liabilities arising from past or future

24

Table of Contents

releases of, or exposures to, hazardous substances, may exceed our estimates. We may also be subject to additional environmental claims for personal injury or cost recovery actions for remediation of facilities in the future based on our past, present or future business activities.

As a global business, we have a relatively complex tax structure, and there is a risk that tax authorities will disagree with our tax positions.

Since we conduct operations worldwide through our subsidiaries, we are subject to complex transfer pricing regulations in the countries in which we operate. Transfer pricing regulations generally require that, for tax purposes, transactions between us and our affiliates be priced on a basis that would be comparable to an arm's length transaction and that contemporaneous documentation be maintained to support the tax allocation. Although uniform transfer pricing standards are emerging in many of the countries in which we operate, there is still a relatively high degree of uncertainty and inherent subjectivity in complying with these rules. To the extent that any tax authority disagrees with our transfer pricing policies, we could become subject to significant tax liabilities and penalties. Our tax returns are subject to review by taxing authorities in the jurisdictions in which we operate. Although we believe that we have provided for all tax exposures, the ultimate outcome of a tax review could differ materially from our provisions.

We could be subject to changes in tax rates, the adoption of new tax legislation or exposure to additional tax liabilities.

Our future effective tax rate and cash tax obligations could be adversely affected by shifts in our mix of earnings in countries with varying statutory tax rates, changes in the valuation of our deferred tax assets or liabilities or changes in tax laws, regulations, interpretations or accounting principles, as well as certain discrete items. In addition, we are subject to regular review and audit by tax authorities. As a result, we have received, and may in the future receive, assessments in multiple jurisdictions on various tax-related assertions. Any adverse outcome of such a review or audit could have a negative effect on our operating results and financial condition. In addition, the determination of our worldwide provision for income taxes and other tax liabilities requires significant judgment, and there are many transactions and calculations where the ultimate tax determination is uncertain. Although we believe our estimates are reasonable, the ultimate tax outcome may differ from the amounts recorded in our financial statements and may materially affect our financial results in the period or periods for which such determination is made. Furthermore, due to shifting economic and political conditions, tax policies, laws, interpretations and rates in various jurisdictions may be subject to significant change, which could materially affect our financial position and results of operations. For example, many countries in Europe, as well as a number of other countries and organizations, have recently proposed, recommended or implemented changes to existing tax laws or have enacted new laws that could significantly increase our effective tax rate or cash tax obligations in countries where we do business or require us to change the manner in which we operate our business.

Risks Related to Our Incorporation in Ireland

Irish law differs from the laws in effect in the United States and may afford less protection to holders of our securities.

The U.S. currently does not have a treaty with Ireland providing for the reciprocal recognition and enforcement of judgments in civil and commercial matters. As such, there is some uncertainty as to whether the courts of Ireland would recognize or enforce judgments of U.S. courts obtained against us or our directors or officers based on U.S. federal or state civil liability laws, including the civil liability provisions of the U.S. federal or state securities laws, or hear actions against us or those persons based on those laws.

As an Irish company, we are governed by the Companies Act 2014 of Ireland, as amended, which differs in some material respects from laws generally applicable to U.S. corporations and shareholders, including, among others, differences relating to interested director and officer transactions and shareholder lawsuits. Likewise, the duties of directors and officers of an Irish company generally are owed to the company only. Shareholders of Irish companies generally do not have a personal right of action against directors or officers of the company and may exercise such rights of action on behalf of the company only in limited circumstances. Accordingly, holders of our securities may have more difficulty protecting their interests than would holders of securities of a corporation incorporated in a jurisdiction of the U.S.

In addition, Irish law allows shareholders to authorize share capital which then can be issued by a board of directors without shareholder approval. Also, subject to specified exceptions, Irish law grants statutory preemptive rights to existing shareholders to subscribe for new issuances of shares for cash. At our annual meeting of shareholders, our shareholders authorized our Board of Directors to issue up to 33% of our issued ordinary shares and further authorized our Board of Directors to issue up to 5% of such shares for cash without first offering them to our existing shareholders. Both of these authorizations will expire after a certain period unless renewed by our shareholders, and we cannot guarantee that the renewal of these authorizations will always

25

Table of Contents

be approved. If the Directors' authority to issue ordinary shares is not renewed, then we may be limited in our ability to use our shares, for example, as consideration for acquisitions.

Changes in tax laws, regulations or treaties, changes in our status under the tax laws of many jurisdictions or adverse determinations by taxing authorities could increase our tax burden or otherwise affect our financial condition or operating results, as well as subject our shareholders to additional taxes.

The realization of any tax benefit related to our incorporation and tax residence in Ireland could be impacted by changes in tax laws, tax treaties or tax regulations or the interpretation or enforcement thereof by the tax authorities of many jurisdictions. From time to time, proposals have been made and/or legislation introduced to change the tax laws of various jurisdictions or limit tax treaty benefits that if enacted could materially increase our tax burden and/or our effective tax rate. Moreover, other legislative proposals could have a material adverse impact on us by overriding certain tax treaties and limiting the treaty benefits on certain payments, which could increase our tax liability. We cannot predict the outcome of any specific legislation in any jurisdiction.

While we monitor proposals that would materially impact our tax burden and/or our effective tax rate and investigate our options, we could still be subject to increased taxation on a going forward basis no matter what action we undertake if certain proposals are enacted, certain tax treaties are amended and/or our interpretation of applicable tax law is challenged and determined to be incorrect. In particular, any changes and/or differing interpretations of applicable tax law that have the effect of disregarding our incorporation in Ireland, limiting our ability to take advantage of tax treaties between jurisdictions, modifying or eliminating the deductibility of various currently deductible payments or increasing the tax burden of operating or being resident in a particular country, could subject us to increased taxation.

Dividends received by our shareholders may be subject to Irish dividend withholding tax.

In certain circumstances, we are required to deduct Irish dividend withholding tax of 25% from dividends paid to our shareholders. In the majority of cases, shareholders residing in the U.S. will not be subject to Irish withholding tax, and shareholders resident in a number of other countries will not be subject to Irish withholding tax provided that they complete certain Irish dividend withholding tax forms. However, some shareholders may be subject to withholding tax, which could discourage the investment in our stock and adversely impact the price of our shares.

Dividends received by our shareholders may be subject to Irish income tax.

Dividends paid in respect of our shares generally are not subject to Irish income tax where the beneficial owner of these dividends is exempt from Irish dividend withholding tax, unless the beneficial owner of the dividend has some connection with Ireland other than his or her shareholding in Allegion.

Our shareholders who receive their dividends subject to Irish dividend withholding tax will generally have no further liability to Irish income tax on the dividends unless the beneficial owner of the dividend has some connection with Ireland other than his or her shareholding in Allegion.

Certain provisions in our Memorandum and Articles of Association, among other things, could prevent or delay an acquisition of us, which could decrease the trading price of our ordinary shares.

Our Memorandum and Articles of Association contains provisions to deter takeover practices, inadequate takeover bids and unsolicited offers. These provisions include, amongst others:

•A provision of our Articles of Association which generally prohibits us from engaging in a business combination with an interested shareholder (being (i) the beneficial owner, directly or indirectly, of 10% or more of our voting shares or (ii) an affiliate or associate of us that has at any time within the last five years been the beneficial owner, directly or indirectly, of 10% or more of our voting shares), subject to certain exceptions;

•Rules regarding how shareholders may present proposals or nominate directors for election at shareholder meetings;

•The right of our Board of Directors to issue preferred shares without shareholder approval in certain circumstances, subject to applicable law; and

•The ability of our Board of Directors to set the number of directors and to fill vacancies on our Board of Directors.

We believe these provisions will provide some protection to our shareholders from coercive or otherwise unfair takeover tactics. These provisions are not intended to make us immune from takeovers. However, these provisions will apply even if the offer may be considered beneficial by some shareholders and could delay or prevent an acquisition that our Board of Directors

26

Table of Contents

determines is in our best interests and our shareholders' best interests. These provisions may also prevent or discourage attempts to remove and replace incumbent directors.

In addition, several mandatory provisions of Irish law could prevent or delay an acquisition of us. For example, Irish law does not permit shareholders of an Irish public limited company to take action by written consent with less than unanimous consent. We also will be subject to various provisions of Irish law relating to mandatory bids, voluntary bids, requirements to make a cash offer and minimum price requirements, as well as substantial acquisition rules and rules requiring the disclosure of interests in our shares in certain circumstances. Also, Irish companies, including us, may alter their Memorandum of Association and Articles of Association only with the approval of at least 75% of the votes of the company’s shareholders cast in person or by proxy at a general meeting of the company.

Item 1B.    UNRESOLVED STAFF COMMENTS

None.

Item 2.    PROPERTIES

We operate through a broad network of sales offices, engineering centers, 30 production and assembly facilities and several distribution centers throughout the world. Our active properties represent about 6.3 million square feet, of which approximately 37% is leased.

We own 16 of our production and assembly facilities, with the remainder under long-term lease arrangements. We believe that our plants have been well maintained, are generally in good condition and are suitable for the conduct of our business.

Item 3. LEGAL PROCEEDINGS

In the normal course of business, we are involved in a variety of lawsuits, claims and legal proceedings, including commercial and contract disputes, employment matters, product liability claims, environmental liabilities, intellectual property disputes and tax-related matters. In our opinion, pending legal matters are not expected to have a material adverse impact on our results of operations, financial condition, liquidity or cash flows.

This item should be read in conjunction with the Company's Risk Factors in Part I, Item 1A for additional information.

Item 4. MINE SAFETY DISCLOSURES

Not applicable.

Item 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND

ISSUER PURCHASES OF EQUITY SECURITIES

Information regarding the principal market for our ordinary shares and related shareholder matters is as follows:

Our ordinary shares are traded on the NYSE under the symbol ALLE. As of February 11, 2021, the number of record holders of ordinary shares was 2,301. Information regarding equity compensation plans required to be disclosed pursuant to this Item is incorporated by reference from our Proxy Statement.

Dividend Policy

Our Board of Directors declared dividends of $0.32 per ordinary share on February 6, 2020, April 8, 2020, September 1, 2020 and December 2, 2020. On February 5, 2021, our Board of Directors declared a dividend of $0.36 per ordinary share payable March 31, 2021. We paid a total of $117.3 million in cash for dividends to ordinary shareholders during the year ended December 31, 2020. Future dividends on our ordinary shares, if any, will be at the discretion of our Board of Directors and will depend on, among other things, our results of operations, cash requirements and surplus, financial condition, contractual restrictions and other factors that the Board of Directors may deem relevant, as well as our ability to pay dividends in compliance with the Irish Companies Act. Under the Irish Companies Act, dividends and distributions may only be made from distributable reserves. Distributable reserves, broadly, means the accumulated realized profits of Allegion plc (ALLE-Ireland) and are unrelated to any U.S. GAAP reporting amount (e.g. retained earnings). As of December 31, 2020, we had distributable reserves of $3.8 billion. In addition, no distribution or dividend may be made unless the net assets of ALLE-Ireland are equal to, or in excess of, the aggregate of ALLE-Ireland’s called up share capital plus undistributable reserves and the distribution does not reduce ALLE-Ireland’s net assets below such aggregate.

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations contains forward-looking statements that involve risks and uncertainties. Our actual results may differ materially from the results discussed in the forward-looking statements. Factors that might cause a difference include, but are not limited to, those discussed under Item 1A. Risk Factors in this Annual Report on Form 10-K. The following section is qualified in its entirety by the more detailed information, including our consolidated financial statements and the notes thereto, which appears elsewhere in this Annual Report.

Overview

Organization

We are a leading global provider of security products and solutions operating in three geographic regions: Americas, EMEA and Asia Pacific. We sell a wide range of security products and solutions for end-users in commercial, institutional and residential markets worldwide, including the education, healthcare, government, hospitality, commercial office and single and multi-family residential markets. Our leading brands include CISA, Interflex, LCN, Schlage, SimonsVoss and Von Duprin.

Recent Developments

COVID-19 Pandemic

In March 2020, a global pandemic was declared by the WHO related to COVID-19. The impacts of the COVID-19 pandemic negatively affected the global economy, disrupted supply chains and created significant volatility and disruption in financial markets. The outbreak and spread of COVID-19 also resulted in a substantial curtailment of business activities worldwide, including the major geographic markets we serve. As part of the efforts to contain the spread of COVID-19, federal, state and local governments have imposed various restrictions on the conduct of business and travel, such as stay-at-home orders, travel restrictions and quarantines. These measures, as well as changes in employee health and safety concerns and consumer spending patterns, trends and preferences, have led to widespread business closures and lower demand for our products, with the most pronounced negative impacts of these measures on our results of operations occurring during the second quarter of 2020. Further, changes in commercial real estate occupancy, constraints on government and institutional budgets and the uncertain business climate have led to declines and delays in new construction activity and discretionary projects, including in many of the commercial and institutional construction markets we serve.

As the pandemic and resulting economic challenges have adversely impacted, and will likely continue to adversely impact us, we continue to closely monitor their effects on all aspects of our business and the markets in which we operate. Throughout the pandemic, our primary focus has been, and continues to be, the health and safety of employees, our business continuity plan, meeting the evolving needs of our customers and the well-being of the many communities around the world in which we operate. During the early months of the pandemic, we experienced temporary production shut-downs due either to government mandate or to help ensure employee safety, most notably in Italy and the Baja region of Mexico. However, the vast majority of our manufacturing facilities have remained open and operational throughout 2020, in part due to the numerous health and safety measures we adopted to promote the health and safety of our workforce and because many of our global operations have been deemed essential businesses. All of our global production and assembly facilities were operational as of December 31, 2020, and while we currently expect they will remain operational for the foreseeable future, such expectation is dependent upon future governmental actions, demand for our products, the stability of our global supply chain and our ability to continue to operate in a safe manner.

We remain focused on business continuity and ensuring our facilities remain operational where safe and appropriate to do so. We will also continue to serve our customers when needed through our channel partners or inventory on hand. To the extent any additional temporary closures or adjustments to production are necessary, such measures will be implemented in a way that allows us to resume operations in an efficient and safe manner, while also minimizing disruption to customers and our overall business, including prudent measures to mitigate, to the extent possible, any financial impacts, although any additional local orders or decrees resulting in new temporary shut-downs will drive further unfavorable impacts to our operations, ability to serve our customers and potentially, our financial position and liquidity. The pandemic will likely continue to impact us in numerous and evolving ways that we may not be able to accurately predict; however, we will continue to closely monitor its impact on our business, employees, customers, suppliers, distribution channels and other business partners, and we believe that our actions taken to date, our financial flexibility and potential measures within our control will allow us to maintain a sound financial position and provide for adequate resources to fund our ongoing operating and financing needs.

Additionally, as a response to the COVID-19 pandemic, on March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act (the "CARES Act") was enacted and signed into law, which included measures to assist companies in response to the COVID-19 pandemic. One measure allowed companies to defer the remittance of the employer portion of the social security tax through December 31, 2020, with half the amount deferred required to be paid by December 31, 2021, and the other half by December 31, 2022. Through December 31, 2020, we have elected to defer approximately $13 million under this provision, which is classified in Accrued expenses and other current liabilities and Other noncurrent liabilities within our Consolidated Balance Sheet. A second measure of the CARES Act raised the limit on business interest deductions from 30% to 50% of adjusted taxable income for tax years 2019 and 2020. This increased interest limitation resulted in approximately $20 million of reduced cash tax payments in 2020. Each of these two measures has resulted in a benefit to our cash flows from operations for the year ended December 31, 2020; however, neither measure is expected to materially impact our effective tax rate, and no income tax effects have been recorded during the year ended December 31, 2020.

The challenges and uncertainties related to the COVID-19 pandemic and its potential impact on our business, results of operations, financial condition and cash flows, as well as a number of other challenges and uncertainties that could affect our businesses are described further under Part I, Item 1A. "Risk Factors."

2020 and 2019 Significant Events

Acquisitions

In December 2020, we acquired Yonomi, Inc. ("Yonomi), a U.S. based smart home integration platform provider and innovation leader in IoT Cloud platforms. Yonomi has been integrated into our Americas segment.

Impairment of Goodwill and Intangible Assets

As a result of the global economic disruption and uncertainty due to the COVID-19 pandemic, we performed interim impairment tests on the goodwill balances of our EMEA and Asia Pacific reporting units, as well as on certain indefinite-lived trade name assets in these two regions, during the first quarter of 2020. As discussed in Notes 5 and 6 to the Consolidated Financial Statements, the results of these interim impairment tests indicated that the estimated fair value of our Asia Pacific reporting unit and three indefinite-lived trade names were impaired. Consequently, goodwill and intangible asset impairment charges totaling $96.3 million were recorded.

Further impairment charges were recorded in our Asia Pacific segment during the year ended December 31, 2020, including $2.6 million related to supply chain disruptions that reduced a brand's expected future cash flows and $2.8 million related to declines in volumes and pricing pressure for a separate subsidiary in the region.

Loss on Assets Held for Sale

The assets and liabilities of our QMI business met the criteria to be classified as held for sale as of December 31, 2020. Accordingly, QMI's net assets, which primarily included working capital and long-lived assets, were written down to fair value, estimated based on expected sales proceeds, less cost to sell, resulting in a Loss on assets held for sale of $37.9 million.

Turkey and Colombia Divestitures

In 2019, we closed our production facility in Turkey to help streamline our footprint in EMEA and subsequently sold certain of the production assets, which represented a business, for total proceeds of approximately $4.1 million. We recorded a loss on divestiture of $24.2 million ($25.5 million, net of tax), primarily driven by the reclassification of $25.0 million of accumulated foreign currency translation adjustments to earnings upon sale. We also sold our interests in our Colombia operations in 2019 for a nominal amount, recording a net loss on divestiture of $5.9 million, of which $1.2 million related to the reclassification of accumulated foreign currency translation adjustments to earnings upon sale.

2020 Dividends and Share Repurchases

We paid quarterly dividends of $0.32 per ordinary share to shareholders on record as of March 17, 2020, June 16, 2020, September 16, 2020, and December 16, 2020. We paid a total of $117.3 million in cash for dividends to ordinary shareholders and repurchased approximately 1.9 million shares for approximately $208.8 million during the year ended December 31, 2020.

Table of Contents

Other Financing Activities

In 2019, we issued $400.0 million of 3.500% Senior Notes due 2029 (the "3.500% Senior Notes"). Net proceeds from the issuance of the 3.500% Senior Notes, along with cash on hand, were utilized to make a $400.0 million principal payment to partially pay down the Company's outstanding term loan facility (the "Term Facility") balance. As a result of this payment, we have satisfied our obligation to make quarterly installments on the Term Facility up to its maturity date, with the remaining outstanding balance of $238.8 million due on September 12, 2022.

Subsequent Event

Effective January 1, 2021, we have combined our EMEA and Asia Pacific operations into a new segment named Allegion International, in addition to renaming our Americas segment "Allegion Americas". The new Allegion International segment has been created to drive speed and efficiency, simplify our operating segments and optimize our non-U.S. operations.

The discussions that follow describe the significant factors contributing to the changes in our results of operations for the years presented and form the basis used by management to evaluate the financial performance of the business. For a discussion of our results of operations for the year ended December 31, 2019, compared to the year ended December 31, 2018, see “Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our 2019 Annual Report on Form 10-K filed with the SEC on February 18, 2020.

Net Revenues

Net revenues for the year ended December 31, 2020, decreased by 4.7%, or $134.1 million, compared to the same period in 2019, due to the following:

Pricing	1.0	%
Volume	(5.8)	%
Divestitures	(0.3)	%
Currency exchange rates	0.4	%
Total	(4.7)	%

The decrease in Net revenues was principally driven by lower volumes across all regions, primarily due to the economic challenges stemming from the ongoing COVID-19 pandemic, particularly during the second quarter of 2020. The decrease was, to a lesser degree, due to the impact of the divestitures of our Colombia and Turkey businesses in 2019, as discussed above. These decreases were slightly offset by improved pricing and the impact of foreign currency exchange rate movements.

Pricing includes increases or decreases of price, including discounts, surcharges and/or other sales deductions, on our existing products and services. Volume includes increases or decreases of revenue due to changes in unit volume of existing products and services, as well as new products and services.

Cost of Goods Sold

For the year ended December 31, 2020, Cost of goods sold as a percentage of Net revenues increased to 56.7% from 56.1%, due to the following:

35

Table of Contents

Inflation in excess of pricing and productivity	0.2	%
Volume / product mix	0.8	%
Divestitures	(0.1)	%
Currency exchange rates	(0.2)	%
Restructuring expenses	(0.1)	%
Total	0.6	%

Costs of goods sold as a percentage of Net revenues for the year ended December 31, 2020, increased primarily due to the impact of reduced volumes and product mix and, to a lesser extent, inflation in excess of pricing and productivity. Inflation in excess of pricing and productivity was driven by productivity challenges stemming from the temporary closures during the second quarter discussed above; labor inefficiencies, such as increased absenteeism; and, increased costs related to ensuring a safe and healthy work environment in light of the COVID-19 pandemic. These increases were partially offset by certain non-U.S. government incentives, which were included within inflation in excess of pricing and productivity, as well as the impacts of the divestitures discussed above, foreign currency exchange rate movements and a year-over-year decrease in restructuring expenses. The year-over-year decrease in restructuring expenses impacting Costs of goods sold is due to the prior year restructuring costs related to the closure of our production facility in Turkey in 2019.

Inflation in excess of pricing and productivity includes the impact to Cost of goods sold from pricing, as defined above, in addition to productivity and inflation. Productivity represents improvements in unit costs of materials and cost reductions related to improvements to our manufacturing design and processes. Inflation includes unit costs for the current period compared to the average actual cost for the prior period, multiplied by current year volumes.

Volume/product mix represents the impact due to increases or decreases of revenue due to changes in unit volume, including new products and services, including the effect of changes in the mix of products and services sold on Cost of goods sold.

Selling and Administrative Expenses

For the year ended December 31, 2020, Selling and administrative expenses as a percentage of Net revenues decreased to 23.4% from 23.9%, due to the following:

Productivity in excess of inflation	(2.3)	%
Volume leverage	1.4	%
Investment spending	0.1	%
Currency exchange rates	(0.1)	%
Restructuring / acquisition expenses	0.4	%
Total	(0.5)	%

Selling and administrative expenses as a percentage of Net revenues for the year ended December 31, 2020, decreased primarily due to productivity benefits in excess of inflation and foreign currency exchange rate movements. These decreases were partially offset by unfavorable leverage due to lower volumes, increased investment spending and a year-over-year increase in restructuring and acquisition expenses.

Productivity in excess of inflation includes the impact from reductions in selling and administrative expenses due to productivity projects and current period costs of ongoing selling and administrative functions compared to the same ongoing expenses in the prior period. Productivity in excess of inflation also reflects the benefits of certain non-U.S. government incentives, reductions in variable compensation and reductions or delays of other business spending in the current year, in response to the COVID-19 pandemic.

Volume leverage represents the contribution margin related to changes in sales volume, excluding the impact of price, productivity, mix and inflation. Expenses related to increased head count for strategic initiatives, new facilities or significant improvements for strategic initiatives and new product development, are captured in Investment spending in the table above.

Operating Income/Margin

Operating income for the year ended December 31, 2020, decreased $161.6 million from the same period in 2019, and Operating margin decreased to 14.8% from 19.8%, due to the following:

36

Table of Contents

In millions	Operating Income		Operating Margin
December 31, 2019	$	565.1	19.8	%
Pricing and productivity in excess of inflation	66.7		2.1	%
Volume / product mix	(94.9)		(2.3)	%
Currency exchange rates	8.6		0.2	%
Investment spending	(2.1)		(0.1)	%
Divestitures	0.6		0.1	%
Restructuring / acquisition expenses	(6.8)		(0.3)	%
Impairment of goodwill and intangible assets	(95.8)		(3.4)	%
Loss on assets held for sale	(37.9)		(1.3)	%
December 31, 2020	$	403.5	14.8	%

The decreases in Operating income and Operating margin were largely driven by our current year goodwill and intangible asset impairment charges and loss on assets held for sale related to our QMI business. As a result of the global economic disruption and uncertainty due to the COVID-19 pandemic, we determined a triggering event had occurred as of March 31, 2020, and performed interim impairment testing on the goodwill balances of our EMEA and Asia Pacific reporting units, as well as on certain indefinite-lived trade name assets in these two regions, which resulted in impairment charges totaling $96.3 million. Additional intangible asset impairments of $2.6 million and $2.8 million were recorded in our Asia Pacific segment in the third and fourth quarters of 2020, respectively. Further, as we concluded that the net assets of our QMI business met the criteria to be classified as held for sale as of December 31, 2020, they were written down to fair value, estimated based on expected sales proceeds, less cost to sell, which resulted in a loss of $37.9 million.

The decreases in Operating income and Operating margin were also attributable to unfavorable volume/product mix, a year-over-year increase in restructuring and acquisition expenses and increased investment spending. These decreases were partially offset by pricing improvements and productivity in excess of inflation, foreign currency exchange rate movements and the impact of the divestitures discussed above.

Interest Expense

Interest expense for the year ended December 31, 2020, decreased $4.9 million compared to 2019, which is due to a lower weighted-average interest rate during the current year on our outstanding indebtedness and a $2.7 million prior year charge for the write-off of previously deferred financing costs related to the Term Facility, which did not recur in the current period.

Loss on Divestitures

In 2019, we closed our production facility in Turkey and subsequently sold certain of the production assets thereof, which represented a business, for total proceeds of approximately $4.1 million. We recorded a loss on divestiture of $24.2 million ($25.5 million, net of tax), primarily driven by the reclassification of $25.0 million of accumulated foreign currency translation adjustments to earnings upon sale. We also sold our interests in our Colombia operations in 2019 for a nominal amount, recording a net loss on divestiture of $5.9 million, of which $1.2 million related to the reclassification of accumulated foreign currency translation adjustments to earnings upon sale.

Other (Income) Expense, net

The components of Other (income) expense, net, for the years ended December 31 were as follows:

In millions	2020		2019
Interest income	$	(0.9)	$	(1.8)
Foreign currency exchange loss	0.7		1.8
(Earnings) loss from equity method investments	(0.3)		0.1
Net periodic pension and postretirement benefit (income) cost, less service cost	(2.2)		6.8
Other	(10.3)		(3.1)
Other (income) expense, net	$	(13.0)	$	3.8

37

Table of Contents

For the year ended December 31, 2020, Other (income) expense, net was favorable $16.8 million compared to 2019, primarily due to gains of $12.8 million related to the reclassification to earnings of accumulated foreign currency translation adjustments upon the liquidation of two legal entities in our EMEA region, which are included within Other in the table above, as well as favorable net periodic pension and postretirement benefit (income) cost, less service cost in 2020 compared to 2019.

Provision for Income Taxes

For the year ended December 31, 2020, our effective tax rate was 13.9%, compared to 15.4% for the year ended December 31, 2019. The decrease in the effective tax rate was primarily due to the favorable mix of income earned in lower tax rate jurisdictions, partially offset by the unfavorable tax impact related to goodwill and intangible asset impairment charges and the unfavorable year-over-year change in the amounts recognized for valuation allowances.

Review of Business Segments

We operate in and report financial results for three segments: Americas, EMEA and Asia Pacific. Beginning in the second quarter of 2020, results for the Company's India operations have been included within the Asia Pacific segment results, due to an operational change. This change did not result in a material impact to Segment results of operations for either the EMEA or Asia Pacific segment. These segments represent the level at which our chief operating decision maker reviews company financial performance and makes operating decisions.

Segment operating income (loss) is the measure of profit and loss that our chief operating decision maker uses to evaluate the financial performance of the business and as the basis for resource allocation, performance reviews and compensation. For these reasons, we believe that Segment operating income (loss) represents the most relevant measure of Segment profit and loss. Our chief operating decision maker may exclude certain charges or gains, such as corporate charges and other special charges, to arrive at a Segment operating income (loss) that is a more meaningful measure of profit and loss upon which to base our operating decisions. We define Segment operating margin as Segment operating income (loss) as a percentage of the segment's Net revenues.

The segment discussions that follow describe the significant factors contributing to the changes in results for each segment included in Net earnings.

Americas

Our Americas segment is a leading provider of security products and solutions in approximately 30 countries throughout North America, Central America, the Caribbean and South America. The segment sells a broad range of products and solutions including, locks, locksets, portable locks, key systems, door closers, exit devices, doors and door systems, electronic products and access control systems to end-users in commercial, institutional and residential facilities, including the education, healthcare, government, hospitality, commercial office and single and multi-family residential markets. This segment’s primary brands are LCN, Schlage, Steelcraft, Technical Glass Products ("TGP") and Von Duprin.

Net revenues

Net revenues for the year ended December 31, 2020, decreased by 4.6%, or $97.8 million, compared to the same period in 2019, due to the following: 

Pricing	1.1	%
Volume	(5.3)	%
Divestitures	(0.4)	%
Total	(4.6)	%

The decrease in Net revenues was principally driven by lower volumes due to the economic challenges stemming from the ongoing COVID-19 pandemic, as well as the impact of the divestiture of our Colombia business in 2019. These decreases were partially offset by improved pricing. Net revenues from residential products for the year ended December 31, 2020, increased mid-single digits compared to the same period in the prior year, primarily driven by higher volumes. Net revenues from non-residential products for the year ended December 31, 2020, decreased high single digits compared to the prior year, primarily driven by lower volumes. As a result of the COVID-19 pandemic, there have been changes in commercial real estate occupancy, constraints on government and institutional budgets and an overall uncertain business climate, which have led to declines and delays in new construction activity and discretionary projects in the non-residential construction markets we serve. These challenges are expected to continue in 2021, but the long-term impacts of the pandemic and related market disruption are not yet known.

Additionally, as end-users have continued to adopt newer technologies in their facilities and homes, accelerated by the increasing adoption of the Internet of Things ("IoT"), growth in electronic security products and solutions has become an increased metric monitored by management and of focus to our investors. For the year ended December 31, 2020, Net revenues from the sale of electronic products in the Americas segment decreased mid-single digits compared to the same period in the prior year, primarily driven by lower volumes due to delays in discretionary projects. Electronic products include all electrified product categories including, but not limited to, electronic locks, access controls and electrified exit devices.

Operating income/margin

Segment operating income for the year ended December 31, 2020, decreased $31.4 million, and Segment operating margin decreased to 28.8% from 28.9% compared to the same period in 2019, due to the following:

In millions	Operating Income		Operating Margin
December 31, 2019	$	611.6	28.9	%
Pricing and productivity in excess of inflation	31.0		1.1	%
Volume / product mix	(64.8)		(1.5)	%
Currency exchange rates	5.9		0.3	%
Investment spending	(2.0)		(0.1)	%
Divestitures	0.7		0.2	%
Restructuring / acquisition expenses	(2.2)		(0.1)	%
December 31, 2020	$	580.2	28.8	%

The decreases in Segment operating income and Segment operating margin were primarily due to unfavorable volume/product mix, as well as increased investment spending and year-over-year increases in restructuring and acquisition expenses. These decreases were partially offset by pricing improvements and productivity in excess of inflation, foreign currency exchange rate movements and the impact of the divestiture of our Colombia business in 2019. As a result of the ongoing COVID-19 pandemic, certain of our facilities in the Americas experienced productivity challenges due to temporary closures and lower volume and demand, particularly during the second quarter; however, these productivity decreases were more than offset by reductions in variable compensation and reductions or delays of other business spending.

EMEA

Our EMEA segment provides security products, services and solutions in approximately 80 countries throughout Europe, the Middle East and Africa. The segment offers end-users a broad range of products, services and solutions including, locks, locksets, portable locks, key systems, door closers, exit devices, doors and door systems, electronic products and access control systems, as well as time and attendance and workforce productivity solutions. This segment’s primary brands are AXA, Bricard, Briton, CISA, Interflex and SimonsVoss. This segment also resells LCN, Schlage and Von Duprin products, primarily in the Middle East.

Net revenues

Net revenues for the year ended December 31, 2020, decreased by 3.1%, or $17.9 million, compared to the same period in 2019, due to the following:

Pricing	0.9	%
Volume	(6.0)	%
Divestitures	(0.2)	%
Currency exchange rates	2.2	%
Total	(3.1)	%

The decrease in Net revenues was principally driven by lower volumes due to the economic challenges stemming from the ongoing COVID-19 pandemic, particularly during the second quarter, as well as the divestiture of our Turkey business in 2019. These decreases were partially offset by improved pricing and favorable foreign currency exchange rate movements.

Operating income (loss)/margin

Segment operating income (loss) for the year ended December 31, 2020, was unfavorable $39.7 million, and Segment operating margin decreased to (1.0)% from 6.0% compared to the same period in 2019, due to the following:

In millions	Operating Income (Loss)		Operating Margin
December 31, 2019	$	34.3	6.0	%
Pricing and productivity in excess of inflation	15.0		2.6	%
Volume / product mix	(22.4)		(3.8)	%
Currency exchange rates	2.8		0.4	%
Investment spending	(0.3)		(0.1)	%
Divestitures	(0.1)		—	%
Restructuring / acquisition expenses	3.1		0.5	%
Impairment of intangible assets	0.1		—	%
Loss on assets held for sale	(37.9)		(6.6)	%
December 31, 2020	$	(5.4)	(1.0)	%

Segment operating income (loss) was unfavorable primarily due to the loss on assets held for sale related to our QMI business, unfavorable volume/product mix and, to a lesser extent, increased investment spending and the impact of the divestiture of our Turkey business in 2019. These decreases were partially offset by pricing improvements and productivity in excess of inflation, foreign currency exchange rate movements, year-over-year decreases in restructuring and acquisition expenses and intangible asset impairment charges. Certain of our facilities in EMEA did experience productivity challenges as a result of the COVID-19 pandemic due to temporary closures and lower volume and demand, particularly during the second quarter in Italy; however, this was more than offset by the benefits of certain government incentives and reductions in variable compensation and other business spending. Pricing and productivity in excess of inflation also includes the impact of a $5.1 million environmental remediation charge incurred during the fourth quarter of 2020.

Segment operating margin decreased primarily due to the loss on assets held for sale, unfavorable volume/product mix and increased investment spending. These decreases were partially offset by pricing improvements and productivity in excess of inflation, foreign currency exchange rate movements and year-over-year decreases in restructuring and acquisition expenses.

Asia Pacific

Our Asia Pacific segment provides security products, services and solutions in approximately 15 countries throughout the Asia Pacific region. The segment offers end-users a broad range of products, services and solutions including, locks, locksets, portable locks, key systems, door closers, exit devices, electronic products and access control systems. This segment’s primary brands are Brio, Briton, FSH, Gainsborough, Legge, Milre and Schlage.

Net revenues

Net revenues for the year ended December 31, 2020, decreased by 11.0%, or $18.4 million, compared to the same period in 2019, due to the following:

Pricing	(0.7)	%
Volume	(9.9)	%
Currency exchange rates	(0.4)	%
Total	(11.0)	%

The decrease in Net revenues was principally driven by lower volumes in our Korea business, declines attributable to the economic challenges stemming from the ongoing COVID-19 pandemic and weakness in end markets throughout the region. Unfavorable foreign currency exchange rate movements and lower pricing also contributed to the decrease in Net revenues during the current year.

Operating income (loss)/margin

Segment operating income (loss) for the year ended December 31, 2020, was unfavorable $97.2 million, and Segment operating margin decreased to (65.1)% from 0.3% compared to the same period in 2019, due to the following:

In millions	Operating Income (Loss)		Operating Margin
December 31, 2019	$	0.5	0.3	%
Pricing and productivity in excess of inflation	8.2		4.9	%
Volume / product mix	(7.7)		(4.9)	%
Currency exchange rates	(0.1)		(0.1)	%
Investment spending	0.8		0.5	%
Restructuring / acquisition expenses	(2.5)		(1.5)	%
Impairment of goodwill and intangible assets	(95.9)		(64.3)	%
December 31, 2020	$	(96.7)	(65.1)	%

The decreases to Segment operating income (loss) and Segment operating margin were both primarily due to an $88.1 million goodwill impairment charge in the first quarter of 2020 and increased year-over-year intangible asset impairment charges, as well as unfavorable volume/product mix, year-over-year increases in restructuring and acquisition expenses and foreign currency exchange rate movements. These decreases were partially offset by productivity improvements in excess of lower pricing and inflation and decreased investment spending. Pricing and productivity in excess of inflation includes the impact of a $4.0 million gain on the sale of a building within the region during the fourth quarter of 2020.

Liquidity and Capital Resources

Sources and uses of liquidity

Our primary source of liquidity is cash provided by operating activities. Cash provided by operating activities is used to invest in new product development and fund capital expenditures and working capital requirements and is expected to be adequate to service any future debt, pay any declared dividends and potentially fund acquisitions and share repurchases. Our ability to fund these capital needs depends on our ongoing ability to generate cash from our operating activities and to access our borrowing facilities (including unused availability under our Revolving Facility) and capital markets.

Throughout 2020, we have closely monitored the developments related to the COVID-19 pandemic, including the resulting uncertainties around customer demand, supply chain disruption, the availability and cost of materials, customer and supplier financial condition, levels of liquidity and our ongoing compliance with debt covenants. While our business and results of

41

Table of Contents

operations have been negatively impacted by the pandemic and the resulting global economic slowdown, we have no required principal payments on our long-term debt until September 2022, maintain cash and cash equivalents of $480.4 million and have unused availability of $485.0 million under our Revolving Facility as of December 31, 2020. Further, our business operates with low capital intensity, providing financial flexibility during this time of continued uncertainty. We believe that our actions taken to date, future cash provided by operating activities, availability under our Revolving Facility, access to funds on hand and capital markets, as well as other potential measures within our control to maintain a sound financial position and liquidity, will provide adequate resources to fund our operating and financing needs.

The following table reflects the major categories of cash flows for the years ended December 31. For additional details, please see the Consolidated Statements of Cash Flows in the Consolidated Financial Statements.

In millions	2020		2019
Net cash provided by operating activities	$	490.3	$	488.2
Net cash used in investing activities	(56.7)		(77.6)
Net cash used in financing activities	$	(321.9)	$	(342.2)

Operating activities

Net cash provided by operating activities for the year ended December 31, 2020, increased $2.1 million compared to 2019. As discussed above, Net cash provided by operating activities for the year ended December 31, 2020, included benefits totaling approximately $30 million due to measures included in the CARES Act.

Investing activities

Net cash used in investing activities for the year ended December 31, 2020, decreased $20.9 million compared to 2019, primarily due to a decrease in capital expenditures.

Financing activities

Net cash used in financing activities for the year ended December 31, 2020, decreased $20.3 million compared to 2019. The year over-year reductions in debt repayments and cash used to repurchase shares of $17.7 million and $17.2 million, respectively, were partially offset by a year-over-year increase in dividend payments to ordinary shareholders of $16.7 million.

Capitalization

At December 31, long-term debt and other borrowings consisted of the following:

In millions	2020		2019
Term Facility	$	238.8	$	238.8

Less current portion of long-term debt	0.2		0.1
Total long-term debt	$	1,429.4	$	1,427.6

As of December 31, 2020, we have an unsecured Credit Agreement in place, consisting of a $700.0 million term loan facility (the “Term Facility”), of which $238.8 million is outstanding, and a $500.0 million revolving credit facility (the “Revolving Facility” and, together with the Term Facility, the “Credit Facilities”). The Credit Facilities mature on September 12, 2022.

At inception, the Term Facility was scheduled to amortize in quarterly installments at the following rates: 1.25% per quarter starting December 31, 2017 through December 31, 2020, 2.5% per quarter from March 31, 2021 through June 30, 2022, with the balance due on September 12, 2022. Principal amounts repaid on the Term Facility may not be reborrowed. During the third

42

Table of Contents

quarter of 2019, we made a $400.0 million principal payment to partially pay down the outstanding Term Facility balance. As a result of this payment, we have satisfied our obligation to make quarterly installments on the Term Facility up to the maturity date, with the remaining outstanding balance due on September 12, 2022.

The Revolving Facility provides aggregate commitments of up to $500.0 million, which includes up to $100.0 million for the issuance of letters of credit. At December 31, 2020, there were no borrowings outstanding on the Revolving Facility, and we had $15.0 million of letters of credit outstanding. Commitments under the Revolving Facility may be reduced at any time without premium or penalty, and amounts repaid may be reborrowed.

Outstanding borrowings under the Credit Facilities accrue interest at our option of (i) a LIBOR rate plus the applicable margin or (ii) a base rate plus the applicable margin. The applicable margin ranges from 1.125% to 1.500% depending on our credit ratings. At December 31, 2020, outstanding borrowings under the Credit Facilities accrue interest at LIBOR plus a margin of 1.250%, resulting in an interest rate of 1.51%.

As of December 31, 2020, we also have $400.0 million outstanding of 3.200% Senior Notes due 2024 (the "3.200% Senior Notes"), $400.0 million outstanding of 3.550% Senior Notes due 2027 (the "3.550% Senior Notes") and $400.0 million outstanding of 3.500% Senior Notes due 2029 (the "3.500% Senior Notes", and all three senior notes collectively, the "Senior Notes"). The Senior Notes require semi-annual interest payments on April 1 and October 1 of each year, and will mature on October 1, 2024, October 1, 2027, and October 1, 2029, respectively.

Historically, the majority of our earnings were considered to be permanently reinvested in jurisdictions where we have made, and intend to continue to make, substantial investments to support the ongoing development and growth of our global operations. At December 31, 2020, we have analyzed our working capital requirements and the potential tax liabilities that would be incurred if certain subsidiaries made distributions and concluded that no material changes to our historic permanent reinvestment assertions are required.

Defined Benefit Plans

Our investment objective in managing defined benefit plan assets is to ensure that all present and future benefit obligations are met as they come due. We seek to achieve this goal while trying to mitigate volatility in plan funded status, contributions and expense by better matching the characteristics of the plan assets to that of the plan liabilities. Global asset allocation decisions are based on a dynamic approach whereby a plan's allocation to fixed income assets increases as the funded status increases. We monitor plan funded status, asset allocation and the impact of market conditions on our defined benefit plans regularly in addition to investment manager performance. None of our defined benefit pension plans have experienced a significant impact on their liquidity due to volatility in the markets. For further details on pension plan activity, see Note 12 to the Consolidated Financial Statements.

Contractual Obligations

The following table summarizes our contractual cash obligations by required payment periods:

In millions	2021		2022-2023		2024-2025		Thereafter		Total
Long-term debt (including current maturities)	$	0.2	$	239.1	$	400.1	$	800.0	$	1,439.4
Interest payments on long-term debt	45.6		85.4		66.0		77.3		274.3
Purchase obligations	462.5		—		—		—		462.5
Operating leases	30.4		38.2		16.8		19.5		104.9
Total contractual cash obligations	$	538.7	$	362.7	$	482.9	$	896.8	$	2,281.1

Future interest payments on variable rate long-term debt are estimated based on the rate in effect as of December 31, 2020. As the timing and amounts of our future expected obligations under our defined benefit plans, income taxes, environmental and product liability matters are uncertain, they have not been included in the contractual cash obligations table above, but rather, are discussed below:

Defined Benefit Pension and Postretirement ("OPEB") Plans

At December 31, 2020, we had net pension liabilities of $20.2 million, which consist of plan assets of $796.9 million and benefit obligations of $817.1 million. It is our objective to contribute to our pension plans in order to ensure adequate funds are available in the plans to make benefit payments to plan participants and beneficiaries when required. At December 31, 2020, the funded status of our qualified pension plan for U.S. employees increased to 98.7% from 93.5% at December 31, 2019. The

43

Table of Contents

funded status for our non-U.S. pension plans increased to 101.8% at December 31, 2020 from 101.1% at December 31, 2019. The funded status for all of our pension plans at December 31, 2020 increased to 97.5% from 95.3% at December 31, 2019. We currently project that approximately $11.4 million will be contributed to our plans worldwide in 2021.

At December 31, 2020, we also had OPEB obligations of $5.2 million. We fund OPEB costs principally on a pay-as-you-go basis as medical costs are incurred by covered retiree populations. Benefit payments, which are net of expected plan participant contributions and Medicare Part D subsidies, are not expected to be material in 2021. See Note 12 to the Consolidated Financial Statements for additional information related to our pension and OPEB obligations.

Income Taxes

At December 31, 2020, we have total unrecognized tax benefits for uncertain tax positions of $41.2 million and $7.6 million of related accrued interest and penalties, net of tax. These liabilities have been excluded from the preceding table as we are unable to reasonably estimate the amount and period in which these liabilities might be paid. See Note 18 to the Consolidated Financial Statements for additional information regarding matters relating to income taxes, including unrecognized tax benefits and tax authority disputes.

Contingent Liabilities

We are involved in various litigation, claims and administrative proceedings, including those related to environmental, asbestos-related and product liability matters. We believe that these liabilities are subject to the uncertainties inherent in estimating future costs for contingent liabilities and will likely be resolved over an extended period of time. See Note 21 to the Consolidated Financial Statements for additional information.

Guarantor Financial Information

In March 2020, the SEC adopted amendments to the financial disclosure requirements applicable to registered debt offerings that include credit enhancements, such as subsidiary guarantees, in Rule 3-10 of Regulation S-X. The amended rules focus on providing material, relevant and decision-useful information regarding guarantees and other credit enhancements, while eliminating certain prescriptive requirements. We adopted these amendments on March 31, 2020. Accordingly, summarized financial information has been presented only for the issuers and guarantors of our registered securities for the most recent fiscal year, and the location of the required disclosures has been moved outside the Notes to the Consolidated Financial Statements and is provided below.

Allegion US Holding Company Inc. ("Allegion US Hold Co") is the issuer of the 3.200% Senior Notes and 3.550% Senior Notes and is the guarantor of the 3.500% Senior Notes. Allegion plc (the “Parent”) is the issuer of the 3.500% Senior Notes and is the guarantor of the 3.200% Senior Notes and 3.550% Senior Notes. Allegion US Hold Co is 100% owned by the Parent and each of the guarantees of Allegion US Hold Co and the Parent is full and unconditional and joint and several.

The 3.200% Senior Notes and the 3.550% Senior Notes are senior unsecured obligations of Allegion US Hold Co and rank equally with all of Allegion US Hold Co’s existing and future senior unsecured and unsubordinated indebtedness. The guarantee of the 3.200% Senior Notes and the 3.550% Senior Notes is the senior unsecured obligation of the Parent and ranks equally with all of Allegion plc’s existing and future senior unsecured and unsubordinated indebtedness. The 3.500% Senior Notes are senior unsecured obligations of the Parent, are guaranteed by Allegion US Hold Co and rank equally with all of Allegion plc’s existing and future senior unsecured indebtedness.

Each guarantee is effectively subordinated to any secured indebtedness of the Guarantor to the extent of the value of the assets securing such indebtedness. The Senior Notes are structurally subordinated to indebtedness and other liabilities of the subsidiaries of the Guarantor, none of which guarantee the notes. The obligations of the Guarantor under its Guarantee are limited as necessary to prevent such Guarantee from constituting a fraudulent conveyance under applicable law and, therefore, are limited to the amount that the Guarantor could guarantee without such Guarantee constituting a fraudulent conveyance; this limitation, however, may not be effective to prevent such Guarantee from constituting a fraudulent conveyance. If the Guarantee was rendered voidable, it could be subordinated by a court to all other indebtedness (including guarantees and other contingent liabilities) of the Guarantor, and, depending on the amount of such indebtedness, the Guarantor’s liability on its Guarantee could be reduced to zero. In such an event, the notes would be structurally subordinated to the indebtedness and other liabilities of the Guarantor.

For further details, terms and conditions of the Senior Notes refer to the Company’s Form 8-K filed October 2, 2017 and Form 8-K filed September 27, 2019.

Critical Accounting Policies

Management’s Discussion and Analysis of Financial Condition and Results of Operations are based upon our Consolidated Financial Statements, which have been prepared in accordance with GAAP. The preparation of financial statements in conformity with those accounting principles requires management to use judgment in making estimates and assumptions based on the relevant information available at the end of each period. These estimates and assumptions have a significant effect on reported amounts of assets and liabilities, revenues and expenses as well as the disclosure of contingent assets and liabilities because they result primarily from the need to make estimates and assumptions on matters that are inherently uncertain. Actual results may differ from estimates. If updated information or actual amounts are different from previous estimates, the revisions are included in our results for the period in which they become known.

The following is a summary of certain accounting estimates and assumptions made by management that we consider critical:

•Goodwill – Goodwill is tested annually during the fourth quarter for impairment or when there is a significant change in events or circumstances that indicate the fair value of a reporting unit is more likely than not less than its carrying amount. Recoverability of goodwill is measured at the reporting unit level and starts with a comparison of the carrying amount of a reporting unit to its estimated fair value. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired. To the extent that the carrying value of a reporting unit exceeds its estimated fair value, a goodwill impairment charge will be recognized for the amount by which the carrying value of the reporting unit exceeds its fair value, not to exceed the carrying amount of the reporting unit's goodwill.

45

Table of Contents

As quoted market prices are not available for our reporting units, the calculation of their estimated fair values is based on two valuation techniques, a discounted cash flow model (income approach) and a market multiple of earnings (market approach), with each method being weighted in the calculation. The income approach relies on the Company’s estimates of revenue growth rates, terminal growth rates, margin assumptions and discount rates to estimate future cash flows and explicitly addresses factors such as timing, with due consideration given to forecasting risk. The market approach requires determining an appropriate peer group, which is utilized to derive estimated fair values of our reporting units based on selected market multiples. The market approach reflects the market’s expectations for future growth and risk, with adjustments to account for differences between the selected peer group companies and the subject reporting units.

As a result of the global economic disruption and uncertainty due to the COVID-19 pandemic, we concluded a triggering event had occurred as of March 31, 2020, and accordingly, performed interim impairment testing on the goodwill balances of our EMEA and Asia Pacific reporting units. Given the high degree of market volatility and lack of reliable market data that existed as of March 31, 2020, we determined a discounted cash flow model (income approach) provided the best approximation of fair value of the EMEA and Asia Pacific reporting units for the purpose of performing these interim tests. This was a change in estimate, as historically our determination of reporting unit fair values has been estimated based on both an income and a market approach, as discussed above, with each method being weighted in the calculation. The results of the interim impairment testing indicated the estimated fair value of the Asia Pacific reporting unit was less than its carrying value, and consequently, a goodwill impairment charge of $88.1 million was recorded.

As markets stabilized throughout the year, we reverted to utilizing both an income and market approach while performing our annual impairment test in the fourth quarter. The estimated fair values for each of our reporting units exceeded their carrying values by more than 20% for the annual 2020 goodwill impairment test, completed in the fourth quarter. Assessing the fair value of our reporting units includes, among other things, making key assumptions for estimating future cash flows and appropriate market multiples. These assumptions are subject to a high degree of judgment and complexity. We make every effort to estimate future cash flows as accurately as possible with the information available at the time the forecast is developed. However, changes in assumptions and estimates may affect the estimated fair value of the reporting unit and could result in impairment charges in future periods. Factors that have the potential to create variances in the estimated fair value of the reporting unit include, but are not limited to, the following:

•Decreases in estimated market sizes or market growth rates due to greater-than-expected declines in volumes, pricing pressures or disruptive technology;

•Declines in our market share and penetration assumptions due to increased competition or an inability to develop or launch new products;

•The impacts of market volatility, including greater-than-expected declines in pricing, reductions in volumes or fluctuations in foreign exchange rates;

•The level of success of on-going and future research and development efforts, including those related to acquisitions, and increases in the research and development costs necessary to obtain regulatory approvals and launch new products;

•Increases in the price or decreases in the availability of key commodities and the impact of higher energy prices; and

•Increases in our market-participant risk-adjusted weighted-average cost of capital.

•Indefinite-lived intangible assets – Similar to goodwill, indefinite-lived intangible assets are tested annually during the fourth quarter for impairment or when there is a significant change in events or circumstances that indicate the fair value of the asset is more likely than not less than its carrying amount. Recoverability of indefinite-lived intangible assets is determined on a relief from royalty methodology, which is based on the implied royalty paid, at an appropriate discount rate, to license the use of an asset rather than owning the asset. The present value of the after-tax cost savings (i.e. royalty relief) indicates the estimated fair value of the asset. Any excess of the carrying value over the estimated fair value is recognized as an impairment loss equal to that excess. During the first quarter of 2020, we concluded the global economic disruption and uncertainty due to the COVID-19 pandemic to be a triggering event. Accordingly, interim impairment tests on certain indefinite-lived trade names were performed as of March 31, 2020. Based on these tests, it was determined that three of our indefinite-lived trade names in the EMEA and Asia Pacific segments were impaired, and impairment charges totaling $8.2 million were recorded.

A significant increase in the discount rate, decrease in the terminal growth rate, decrease in the royalty rate or substantial reductions in future revenue projections could have a negative impact on the estimated fair values of any of our indefinite-lived intangible assets.

•Income taxes – We account for income taxes in accordance with ASC Topic 740. Deferred tax assets and liabilities are determined based on temporary differences between financial reporting and tax bases of assets and liabilities, applying enacted tax rates expected to be in effect for the year in which the differences are expected to reverse. We recognize future tax benefits, such as net operating losses and non-U.S. tax credits, to the extent that realizing these benefits is considered in our judgment to be more likely than not. We regularly review the recoverability of our deferred tax assets considering our historic profitability, projected future taxable income, timing of the reversals of existing temporary differences and the feasibility of our tax planning strategies. Where appropriate, we record a valuation allowance with respect to future tax benefits.

The provision for income taxes involves a significant amount of management judgment regarding interpretation of relevant facts and laws in the jurisdictions in which we operate. Future changes in applicable laws, projected levels of taxable income and tax planning could change the effective tax rate and tax balances recorded by us. In addition, tax authorities periodically review income tax returns filed by us and can raise issues regarding our filing positions, timing and amount of income or deductions and the allocation of income among the jurisdictions in which we operate. A significant period of time may elapse between the filing of an income tax return and the ultimate resolution of an issue raised by a revenue authority with respect to that return. We believe that we have adequately provided for any reasonably foreseeable resolution of these matters. We will adjust our estimates if significant events so dictate. To the extent that the ultimate results differ from our original or adjusted estimates, the effect will be recorded in the provision for income taxes in the period that the matter is finally resolved.

•Defined benefit plans – We provide several U.S. and non-U.S. defined benefit pension plan benefits to eligible employees and retirees. Our noncontributory defined benefit pension plans covering non-collectively bargained U.S. employees provide benefits on an average pay formula while most plans for collectively bargained U.S. employees provide benefits on a flat dollar benefit formula. The non-U.S. pension plans generally provide benefits based on earnings and years of service. Determining the costs associated with such plans is dependent on various actuarial assumptions including discount rates, expected return on plan assets, employee mortality and turnover rates. Actuarial valuations are performed to determine expense in accordance with GAAP. Actual results may differ from the actuarial assumptions and are generally recorded to Accumulated other comprehensive loss and amortized into earnings over future periods.

We review our actuarial assumptions at each measurement date and make modifications to the assumptions as appropriate. The discount rate and expected return on plan assets are determined as of each measurement date. Discount rates for all plans are established using hypothetical yield curves based on the yields of corporate bonds rated AA quality. Spot rates are developed from the yield curve and used to discount future benefit payments. The expected return on plan assets reflects the average rate of returns expected on the funds invested or to be invested to provide for the benefits included in the projected benefit obligation. The expected return on plan assets is based on what is achievable given the plan’s investment policy, the types of assets held and the target asset allocation. We believe the assumptions utilized in recording our defined benefit obligations are reasonable based on input from our actuaries, outside investment advisors and information as to assumptions used by plan sponsors.

Changes in any of the assumptions can have an impact on the net periodic pension benefit cost. An estimated 0.25% rate decline in the discount rate would increase net periodic pension benefit cost by approximately $1.1 million in 2021, while a 0.25% rate decline in the estimated return on assets would increase net periodic pension benefit cost by approximately $1.9 million.

•Business combinations – The fair value of consideration paid in a business combination is allocated to the tangible and identifiable intangible assets acquired, liabilities assumed and goodwill. Acquired intangible assets primarily include indefinite-lived trade names, customer relationships and completed technologies. The accounting for business combinations involves a considerable amount of judgment and estimation, including the fair value of acquired intangible assets involving projections of future revenues and cash flows that are either discounted at an estimated discount rate or measured at an estimated royalty rate; fair value of other acquired assets and assumed liabilities, including potential contingencies; and the useful lives of the acquired assets. The assumptions used to determine the fair value of acquired intangible assets include projections developed using internal forecasts, available industry and market data, estimates of long-term growth rates, profitability, customer attrition and royalty rates, which are determined at the time of acquisition. An income approach or market approach (or both) is utilized in accordance with accepted valuation models for each acquired intangible asset to determine fair value. The impact of prior or future business combinations on our financial condition or results of operations may be materially impacted by the change in or initial selection of assumptions and estimates.

Item 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to fluctuations in currency exchange rates, interest rates and commodity prices which could impact our results of operations and financial condition.

Foreign Currency Exposures

We have operations throughout the world that manufacture and sell products in various international markets. As a result, we are exposed to movements in exchange rates of various currencies against the U.S. dollar as well as against other currencies throughout the world. We actively manage material currency exposures that are associated with purchases and sales and other assets and liabilities at the legal entity level; however, we do not hedge currency translation risk. We attempt to hedge exposures that cannot be naturally offset to an insignificant amount with foreign currency derivatives. Derivative instruments utilized by us in our hedging activities are viewed as risk management tools, involve little complexity and are not used for trading or speculative purposes. To minimize the risk of counter party non-performance, derivative instrument agreements are made only through major financial institutions with significant experience in such derivative instruments.

We evaluate our exposure to changes in currency exchange rates on our foreign currency derivatives using a sensitivity analysis. The sensitivity analysis is a measurement of the potential loss in fair value based on a percentage change in exchange rates. Based on the firmly committed currency derivative instruments in place at December 31, 2020, a hypothetical change in fair value of those derivative instruments assuming a 10% adverse change in exchange rates would result in an additional unrealized loss of approximately $16.9 million. This amount, when realized, would be partially offset by changes in the fair value of the underlying transactions.

Commodity Price Exposures

We are exposed to volatility in the prices of commodities used in some of our products and we use fixed price contracts to manage this exposure. We do not have committed commodity derivative instruments in place at December 31, 2020.

Interest Rate Exposure

Outstanding borrowings under our Credit Facilities accrue interest at our option of (i) a LIBOR rate plus the applicable margin or (ii) a base rate plus the applicable margin. The applicable margin ranges from 1.125% to 1.500% depending on our credit ratings. At December 31, 2020, the outstanding borrowings of $238.8 million under the Term Facility accrue interest at LIBOR plus a margin of 1.250%. We are also exposed to the risk of rising interest rates to the extent that we fund our operations with short-term or variable-rate borrowings, as we currently have unused availability of $485.0 million under our Revolving Facility as of December 31, 2020. If LIBOR or other applicable base rates of our Credit Facilities increase in the future, our Interest expense could increase.

Item 9A.    CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

The Company's management, including its Chief Executive Officer and Chief Financial Officer, have conducted an evaluation of the effectiveness of the Company's disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act)), as of the end of the period covered by this Annual Report on Form 10-K. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded as of December 31, 2020, that the Company's disclosure controls and procedures were effective in ensuring that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act has been recorded, processed, summarized and reported, within the time periods specified in the Commission's rules and forms, and that such information has been accumulated and communicated to the Company's management including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

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

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined under Exchange Act Rules 13a-15(f) and 15d-15(f). Our 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. Internal control over financial reporting includes those policies and procedures that:

•pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the Company’s assets;

•provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that the Company’s receipts and expenditures are being made only in accordance with authorizations of the Company’s management and directors; and

•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.

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2020. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013). We concluded that our internal control over financial reporting was effective as of December 31, 2020.

The effectiveness of our internal control over financial reporting has been audited by PricewaterhouseCoopers LLP, the independent registered public accounting firm, as stated in their report herein.

(c) Changes in Internal Control Over Financial Reporting

There were no changes in the Company's internal control over financial reporting that occurred during the quarter ended December 31, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Allegion plc

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Allegion plc and its subsidiaries (the “Company”) as of December 31, 2020 and 2019, and the related consolidated statements of comprehensive income, of equity and of cash flows for each of the three years in the period ended December 31, 2020, including the related notes and financial statement schedule listed in the accompanying index (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Change in Accounting Principle

As discussed in Note 11 to the consolidated financial statements, the Company changed the manner in which it accounts for leases in 2019.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

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

Definition and Limitations of Internal Control over Financial Reporting

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

F-1

Table of Contents

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.

Critical Audit Matters

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

Goodwill Impairment Assessments - EMEA and Asia Pacific Reporting Units

As described in Notes 2 and 5 to the consolidated financial statements, the Company’s consolidated goodwill balance was $819.0 million as of December 31, 2020, and the goodwill associated with the EMEA and Asia Pacific reporting units was $309.9 million and $8.0 million, respectively. As of March 31, 2020, management identified a triggering event for the EMEA and Asia Pacific reporting units, and as a result, performed interim goodwill impairment analyses. The results of the impairment testing indicated that the estimated fair value of the Asia Pacific reporting unit was less than its carrying value, and as such, the Company recorded an impairment of $88.1 million. For the impairment analyses performed as of March 31, 2020, the estimated fair values of the EMEA and Asia Pacific reporting units were based on a discounted cash flow model (income approach). Goodwill is tested annually for impairment during the fourth quarter or whenever there is a significant change in events or circumstances that indicate that the fair value of the reporting unit is more likely than not less than the carrying amount of the reporting unit. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired. To the extent that the carrying value of the reporting unit exceeds its estimated fair value, a goodwill impairment charge will be recognized for the amount by which the carrying value of the reporting unit exceeds its fair value, not to exceed the carrying amount of goodwill. For the annual impairment analyses, the estimated fair values of the EMEA and Asia Pacific reporting units were based on two valuation techniques, a discounted cash flow model and a market multiple of earnings (market approach), with each method being weighted in the calculation. As disclosed by management, the income approach relies on management’s estimates of revenue growth rates, terminal growth rates, margin assumptions, and discount rates. The market approach requires the determination of an appropriate peer group, which is utilized to derive estimated fair values based on selected market multiples.

The principal considerations for our determination that performing procedures relating to the goodwill impairment assessment of EMEA and Asia Pacific reporting units is a critical audit matter are (i) the significant judgment by management when developing the fair value measurements of the reporting units; (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management’s significant assumptions related to revenue growth rates, terminal growth rates, margin assumptions, discount rates, peer group determination, and market multiple selections; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s goodwill impairment assessment, including controls over the valuation of the Company’s EMEA and Asia Pacific reporting units. These procedures also included, among others (i) testing management’s process for developing the fair value measurements of the reporting units; (ii) evaluating the appropriateness of the discounted cash flow and market multiple of earnings models; (iii) testing the completeness and accuracy of underlying data used in the models; and (iv) evaluating the reasonableness of significant assumptions used by management related to revenue growth rates, terminal growth rates, margin assumptions, discount rates, peer group determination, and market multiple selections. Evaluating management’s assumptions related to revenue growth rates and margin assumptions involved evaluating whether the assumptions used by management were reasonable considering (i) the current and past performance of the reporting units, (ii) the consistency with external market and industry data, and (iii) whether these assumptions were consistent with evidence obtained in other areas of the audit. Evaluating the Company’s peer group determination included assessing the appropriateness of the identified peer companies. Professionals with specialized skill and knowledge were used to assist in the evaluation of management’s discounted cash flow and market multiple models, and management’s significant assumptions related to terminal growth rates, discount rates, selected peer group, and market multiples.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 – DESCRIPTION OF COMPANY AND BASIS OF PRESENTATION

Allegion plc, an Irish public limited company, and its consolidated subsidiaries ("Allegion" or "the Company") are a leading global company that provides security products and solutions that keep people and assets safe and secure in the places where they reside, work and thrive. Allegion creates peace of mind by pioneering safety and security with a vision of seamless access and a safer world. The Company offers an extensive and versatile portfolio of mechanical and electronic security products and solutions across a range of market-leading brands including CISA®, Interflex®, LCN®, Schlage®, SimonsVoss® and Von Duprin®.

Basis of presentation: The Consolidated Financial Statements were prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") as defined by the Financial Accounting Standards Board ("FASB") within the FASB Accounting Standards Codification ("ASC"). Certain prior-period amounts have been reclassified to conform to the current year presentation.

NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A summary of significant accounting policies used in the preparation of the accompanying Consolidated Financial Statements follows:

Principles of Consolidation: The Consolidated Financial Statements include all controlled subsidiaries of the Company. A noncontrolling interest in a subsidiary is considered an ownership interest in a controlled subsidiary that is not attributable to the Company. The Company includes noncontrolling interests as a component of Total equity in the Consolidated Balance Sheets and the Net earnings attributable to noncontrolling interests are presented as an adjustment from Net earnings used to arrive at Net earnings attributable to Allegion plc in the Consolidated Statements of Comprehensive Income.

Equity method affiliates represent unconsolidated entities over which the Company demonstrates significant influence but does not have a controlling financial interest. The Company is also required to consolidate variable interest entities in which it bears a majority of the risk to the entity’s potential losses or stands to gain from a majority of the entity’s expected returns.

Use of Estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Estimates are based on several factors including the facts and circumstances available at the time the estimates are made, historical experience, risk of loss, general economic conditions and trends and the assessment of the probable future outcome. Some of the more significant estimates include useful lives of property, plant and equipment and intangible assets, purchase price allocations of acquired businesses, valuation of assets and liabilities including goodwill and other intangible assets, product warranties, sales allowances, pension plan benefits, postretirement benefits other than pensions, taxes, lease related assets and liabilities, environmental costs and product liability and other contingencies. Actual results could differ from those estimates. Estimates and assumptions are reviewed periodically, and the effects of changes, if any, are reflected in the Consolidated Statements of Comprehensive Income in the period they are determined.

Currency Translation: Assets and liabilities where the functional currency is not the U.S. dollar have been translated at year-end exchange rates, and income and expense accounts have been translated using average exchange rates throughout the year. Adjustments resulting from the process of translating a subsidiary’s financial statements into the U.S. dollar are recorded to Accumulated other comprehensive loss.

Cash and Cash Equivalents: Cash and cash equivalents include cash on hand, demand deposits and all highly liquid investments with original maturities at the time of purchase of three months or less.

Allowance for Doubtful Accounts: The Company provides for an allowance for doubtful accounts and notes receivable, which represents the best estimate of expected lifetime credit losses inherent in the Company’s accounts and notes receivable portfolios. The Company's estimates are influenced by a continuing credit evaluation of customers' financial condition, trade accounts and notes receivable aging and historical loss experience, as well as reasonable and supportable forecasts of future economic conditions. The Company has reserved $6.2 million and $5.6 million for doubtful accounts and notes receivable as of December 31, 2020 and 2019, respectively.

Inventories: Inventories are stated at the lower of cost and net realizable value using the first-in, first-out (FIFO) method.

F-7

Property, Plant and Equipment: Property, plant and equipment are stated at cost, less accumulated depreciation. Assets placed in service are recorded at cost and depreciated using the straight-line method over the estimated useful life of the asset except for leasehold improvements, which are depreciated over the shorter of their economic useful life or their lease term. Repair and maintenance costs that do not extend the useful life of the asset are expensed as incurred. Major replacements and significant improvements that increase asset values and extend useful lives are capitalized. The range of useful lives used to depreciate property, plant and equipment is as follows:

Buildings	10	to	50	years
Machinery and equipment	2	to	12	years
Software	2	to	7	years

The Company assesses the recoverability of the carrying value of its property, plant and equipment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be fully recoverable. Recoverability is measured by a comparison of the carrying amount of an asset to the future net undiscounted cash flows expected to be generated by the asset. If the undiscounted cash flows are less than the carrying amount of the asset, an impairment loss is recognized for the amount by which the carrying value of the asset exceeds its fair value.

Investments: The Company periodically invests in debt or equity securities of start-up companies and/or development stage technology or other companies without acquiring a controlling interest. The Company applies the equity method of accounting when the Company has the ability to exercise significant influence over the operating and financial decision making of the investee. Investments in equity method affiliates totaled $17.4 million and $18.2 million as of December 31, 2020 and 2019, respectively. Equity investments that have readily determinable fair values in which the Company does not have significant influence are measured at fair value, with any unrealized holding gains and losses being recorded to earnings. Investments without readily determinable fair values are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer and are qualitatively assessed for impairment indicators each reporting period. Investments in debt and equity securities not accounted for under the equity method of accounting totaled $13.7 million and $18.1 million as of December 31, 2020 and 2019, respectively. The Company's investments are principally recorded within Other noncurrent assets within the Consolidated Balance Sheets.

Leases: In accordance with ASC 842, the Company records a right-of-use ("ROU") asset and lease liability for substantially all leases for which it is a lessee. In determining if a contract represents a lease, consideration is given to all relevant facts and circumstances to assess whether or not the contract conveys the right to control the use of an identified asset, either explicit or implicit, for a period of time in exchange for consideration. Judgment and estimation is also required in determining the lease classification and the amount of the ROU asset and corresponding lease liability for each lease, which includes determining the appropriate lease term and an applicable discount rate. The Company assesses the specific terms and conditions of each lease to determine the appropriate classification as either an operating or finance lease. In determining the appropriate length of the lease term, both the minimum period over which lease payments are required plus any renewal options that are both within the Company's control to exercise and reasonably certain of being exercised as of lease commencement are considered. When available, the rate implicit in the lease is utilized as the discount rate to determine the lease liability. If this rate is unavailable, the Company utilizes its incremental borrowing rate as the discount rate, which is the rate at inception of the lease that would hypothetically be incurred to borrow over a similar term the funds needed to purchase the leased asset. Refer to Note 11 for further details on the Company's lease accounting policies.

Goodwill and Intangible Assets: The Company records as goodwill the excess of the purchase price of an acquired business over the fair value of the net assets acquired. Once the final valuation has been performed for each acquisition, adjustments may be recorded. In accordance with ASC 350, "Intangibles—Goodwill and Other", goodwill and other indefinite-lived intangible assets are tested and reviewed annually for impairment during the fourth quarter or whenever there is a significant change in events or circumstances that indicate the fair value of a reporting unit or indefinite-lived intangible asset is more likely than not less than the carrying amount of the asset.

Recoverability of goodwill is measured at the reporting unit level. The carrying amount of a reporting unit is compared to its estimated fair value. If the estimated fair value of a reporting unit exceeds it's carrying amount, goodwill of the reporting unit is not impaired. To the extent that the carrying value of the reporting unit exceeds its estimated fair value, a goodwill impairment charge will be recognized for the amount by which the carrying value of the reporting unit exceeds its fair value, not to exceed the carrying amount of the reporting unit's goodwill. Estimated fair value of the Company's reporting units is based on two valuation techniques, a discounted cash flow model (income approach) and a market multiple of earnings (market approach), with each method being weighted in the calculation.

F-8

As a result of the global economic disruption and uncertainty due to the novel coronavirus ("COVID-19") pandemic, the Company concluded a triggering event had occurred as of March 31, 2020, and accordingly, performed interim impairment tests on the goodwill balances of its EMEA and Asia Pacific reporting units. Given the high degree of market volatility and lack of reliable market data that existed as of March 31, 2020, the Company determined a discounted cash flow model (income approach) provided the best approximation of fair value of these reporting units for the purpose of performing these interim tests. This was a change in estimate, as historically the determination of reporting unit fair values has been estimated based on both an income and a market approach, as discussed above, with each method being weighted in the calculation. As markets stabilized throughout the year, the Company reverted to utilizing both an income and market approach while performing its annual impairment test in the fourth quarter.

Recoverability of other intangible assets with indefinite useful lives (i.e. Trade names) is determined on a relief from royalty methodology, which is based on the implied royalty paid, at an appropriate discount rate, to license the use of an asset rather than owning the asset. The present value of the after-tax cost savings (i.e. royalty relief) indicates the estimated fair value of the asset. Any excess of the carrying value over the estimated fair value is recognized as an impairment loss equal to that excess.

Intangible assets such as completed technologies, patents, customer-related intangible assets and other intangible assets with finite useful lives are amortized on a straight-line basis over their estimated economic lives. The weighted-average useful lives approximate the following:

Customer relationships	20	years
Trade names (finite-lived)	25	years
Completed technologies/patents	10	years
Other	7	years

Recoverability of intangible assets with finite useful lives is assessed in the same manner as property, plant and equipment, as described above.

Income Taxes: The calculation of the Company’s income taxes involves considerable judgment and the use of both estimates and allocations. Deferred tax assets and liabilities are determined based on temporary differences between financial reporting and tax bases of assets and liabilities, applying enacted tax rates expected to be in effect for the year in which the differences are expected to reverse. The Company recognizes future tax benefits, such as net operating losses and tax credits, to the extent that realizing these benefits is considered in its judgment to be more likely than not. The Company regularly reviews the recoverability of its deferred tax assets considering its historic profitability, projected future taxable income, timing of the reversals of existing temporary differences and the feasibility of its tax planning strategies. Where appropriate, the Company records a valuation allowance with respect to future tax benefits.

Cash paid for income taxes, net of refunds, for the twelve months ended December 31, 2020 and 2019 was $82.6 million and $103.0 million, respectively.

Product Warranties: The Company offers a standard warranty with most product sales, and the value of such warranty is included in the contractual sales price. Standard product warranty accruals are recorded at the time of sale and are estimated based upon product warranty terms and historical experience. The Company regularly assesses the adequacy of its liabilities and makes adjustments as necessary based on known or anticipated warranty claims, or as new information becomes available. Refer to Note 21 for further details regarding product warranties.

Revenue Recognition: Net revenues are recognized based on the satisfaction of performance obligations under the terms of a contract. A performance obligation is a promise in a contract to transfer control of a distinct product or to provide a service, or a bundle of products or services, to a customer. The Company has two principal revenue streams, tangible product sales and services. Approximately 99% of consolidated Net revenues involve contracts with a single performance obligation, the transfer of control of a product or bundle of products to a customer. The Company's remaining Net revenues involve services, including installation and consulting. See Note 20 for additional information regarding the Company's revenue recognition policies.

Sales returns and customer disputes involving a question of quantity or price are accounted for as variable consideration, and therefore, as a reduction to Net revenues and as a contra receivable. At December 31, 2020 and 2019, the Company had a customer claim accrual (contra receivable) of $48.6 million and $36.5 million, respectively. All other incentives or incentive programs where the customer is required to reach a certain level of purchases, remain a customer for a certain period, provide a rebate form or is subject to additional requirements are also considered variable consideration and are accounted for as a reduction of revenue and a liability. At December 31, 2020 and 2019, the Company had a sales incentive accrual of $35.0 million and $37.2 million, respectively. Variable consideration is estimated based on the most likely amount expected to be

F-9

received from customers. Each of these accruals represents the Company’s best estimate of the most likely amount expected to be received from customers based on historical experience. These estimates are reviewed regularly for accuracy, and if updated information or actual amounts are different from previous estimates, the revisions are included in the Company’s results for the period in which they become known. Historically, the aggregate differences, if any, between the Company’s estimates and actual amounts in any year have not had a material impact on the Consolidated Financial Statements. The Company also offers a standard warranty with most product sales, and the value of such warranty is included in the contractual price. The corresponding cost of the warranty obligation is accrued as a liability.

Environmental Costs: The Company is subject to laws and regulations relating to protecting the environment. Environmental expenditures relating to current operations are expensed or capitalized as appropriate. Expenditures relating to existing conditions caused by past operations, which do not contribute to current or future revenues, are expensed. Liabilities for remediation costs are recorded when they are probable and can be reasonably estimated, generally no later than the completion of feasibility studies or the Company’s commitment to a plan of action. The assessment of this liability, which is calculated based on existing technology, does not reflect any offset for possible recoveries from insurance companies and is not discounted. Refer to Note 21 for further details related to environmental matters.

Research and Development Costs: The Company conducts research and development activities for the purpose of developing and improving new products and services. These costs are expensed when incurred. For the years ended December 31, 2020, 2019 and 2018, expenses related to research and development activities amounted to approximately $54.4 million, $54.7 million and $54.4 million, respectively, and primarily consist of salaries, wages, benefits, facility costs and other overhead expenses.

Defined Benefit Plans: The Company provides a range of defined benefits, including pension, postretirement and postemployment benefits to eligible current and former employees. Determining the costs associated with such benefits is dependent on various actuarial assumptions, including discount rates, expected return on plan assets, compensation increases, employee mortality and turnover rates. Actuaries perform the required calculations to determine expense in accordance with GAAP. Actual results may differ from the actuarial estimates and are generally recorded to Accumulated other comprehensive loss and amortized into Net earnings over future periods. The Company reviews its actuarial assumptions at each measurement date and makes modifications to the assumptions as appropriate. Refer to Note 12 for further details on employee benefit plans.

Loss Contingencies: Liabilities are recorded for various contingencies arising in the normal course of business, including litigation and administrative proceedings, environmental matters, product liabilities, product warranties, worker’s compensation and other claims. The Company has recorded reserves in the financial statements related to these matters, which are developed using inputs derived from actuarial estimates and historical and anticipated experience data depending on the nature of the reserve and, in certain instances, with consultation of legal counsel, internal and external consultants and engineers. Subject to the uncertainties inherent in estimating future costs for these types of liabilities, the Company believes its estimated reserves are reasonable and does not believe the final determination of the liabilities with respect to these matters would have a material effect on the financial condition, results of operations, liquidity or cash flows of the Company for any year. Refer to Note 21 for further details related to loss contingencies.

Derivative Instruments: The Company periodically enters into cash flow and other derivative transactions to specifically hedge exposure to various risks related to currency and variable interest rates. The Company recognizes all derivatives on the Consolidated Balance Sheets at their fair value as either assets or liabilities. For designated cash flow hedges, the changes in fair value of the derivative contract is recorded to Accumulated other comprehensive loss and reclassified into Net earnings at the time earnings are affected by the hedged transaction. For undesignated derivative transactions, the changes in the fair value of the derivative contract are immediately recognized in Net earnings. Refer to Note 10 for further details regarding derivative instruments.

Recent Accounting Pronouncements

Recently Adopted Accounting Pronouncements:

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." The new guidance within ASU 2016-13, along with related updates (collectively "ASC 326") introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. The new guidance became effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods. Accordingly, the Company adopted ASC 326 on January 1, 2020, using the modified retrospective transition method through a $2.2 million cumulative-effect decrease to retained earnings. The Company has also made updates to its policies and internal controls over financial reporting as a result of adoption.

In August 2018, the FASB issued ASU 2018-15, "Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." The new guidance aligns the requirements for capitalizing implementation costs incurred in a cloud-based hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 became effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods. Accordingly, the Company adopted ASU 2018-15 on January 1, 2020, using the prospective method of adoption, and the adoption did not have a material impact to the Consolidated Financial Statements.

Recently Issued Accounting Pronouncements:

In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." The new guidance is intended to simplify the accounting for income taxes by removing certain exceptions and by updating accounting requirements around franchise taxes, goodwill recognized for tax purposes, the allocation of current and deferred tax expense among legal entities, among other minor changes. The ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted. The Company adopted ASU 2019-12 on January 1, 2021, and the adoption did not have a material impact to the Consolidated Financial Statements.

In January 2020, the FASB issued ASU 2020-01, "Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815." The amendments in ASU 2020-01 clarify the interaction of the accounting for equity securities under Topic 321 and investments accounted for under the equity method of accounting. The ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted. The Company adopted ASU 2020-01 on January 1, 2021, and the adoption did not have a material impact to the Consolidated Financial Statements.

In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." This ASU, along with related updates, provides temporary optional expedients and exceptions for applying GAAP to contract modifications, hedging relationships and other transactions if certain criteria are met in order to ease the potential accounting and financial reporting burden associated with the expected market transition away from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. The ASU is currently effective and may be applied prospectively at any point through December 31, 2022 at the Company’s option. The Company is assessing what impact ASU 2020-04 will have on the Consolidated Financial Statements.

December 31, 2020 (net)	$	501.1	$	309.9	$	8.0	$	819.0

(a)     In 2019, the Company made reclassifications to goodwill across all segments related to a change in how revenue is managed for a specific immaterial product line where revenue previously managed in the Asia Pacific segment is now being managed in the Americas and EMEA segments.

As a result of the global economic disruption and uncertainty due to the COVID-19 pandemic, the Company concluded a triggering event had occurred as of March 31, 2020, and accordingly, performed interim impairment tests on the goodwill balances of its EMEA and Asia Pacific reporting units. As quoted market prices were not available for these reporting units, and given the high degree of market volatility and lack of reliable market data that existed as of March 31, 2020, the Company determined that a discounted cash flow model (income approach) provided the best approximation of fair value of its EMEA and Asia Pacific reporting units for the purpose of performing these interim tests. This approach relied on numerous assumptions and judgments that were subject to various risks and uncertainties. Principal assumptions utilized, all of which are considered Level 3 inputs under the fair value hierarchy (see Note 13), included the Company’s estimates of future revenue and terminal growth rates, margin assumptions and discount rates to estimate future cash flows. The calculations explicitly addressed factors such as timing, with due consideration given to forecasting risk. While assumptions utilized were subject to a high degree of judgment and complexity, the Company made every effort to estimate future cash flows as accurately as possible, given the high degree of economic uncertainty that existed as of March 31, 2020. The results of the interim impairment testing indicated that the estimated fair value of the Asia Pacific reporting unit was less than its carrying value. Consequently, a goodwill impairment charge was recorded for the Asia Pacific reporting unit, as reflected in the table above. As markets stabilized throughout the year, the Company reverted to utilizing both an income and market approach while performing its annual impairment test in the fourth quarter, which resulted in no further impairment charges.

NOTE 6 – INTANGIBLE ASSETS

The following table sets forth the gross amount and related accumulated amortization of the Company’s intangible assets at December 31:

	2020						2019
In millions	Gross carrying amount		Accumulated amortization		Net carrying amount		Gross carrying amount		Accumulated amortization		Net carrying amount
Completed technologies/patents	$	59.9	$	(25.1)	$	34.8	$	59.3	$	(19.2)	$	40.1
Customer relationships	415.5		(130.2)		285.3		412.7		(107.5)		305.2
Trade names (finite-lived)	90.2		(57.4)		32.8		82.5		(49.4)		33.1
Other	27.0		(11.1)		15.9		17.6		(8.1)		9.5
Total finite-lived intangible assets	592.6		$	(223.8)	368.8		572.1		$	(184.2)	387.9
Trade names (indefinite-lived)	118.3				118.3		123.0				123.0
Total	$	710.9			$	487.1	$	695.1			$	510.9

The Company amortizes finite-lived intangible assets on a straight-line basis over their estimated economic lives in accordance with GAAP. Indefinite-lived intangible assets are not subject to amortization, but instead are tested for impairment at least annually (more frequently if certain indicators are present). Intangible asset amortization expense for the years ended 2020, 2019 and 2018, was $31.5 million, $31.2 million and $36.3 million, respectively. Intangible asset amortization expense for 2018 included the amortization of approximately $6 million of backlog revenue that was acquired during an acquisition. Future estimated amortization expense on existing intangible assets in each of the next five years amounts to approximately $28.5 million for 2021, $28.5 million for 2022, $28.4 million for 2023, $28.3 million for 2024 and $27.4 million for 2025.

In accordance with the Company’s indefinite-lived intangible asset impairment testing policy, the Company performs its annual impairment test in the fourth quarter of each year or whenever there is a significant change in events or circumstances that indicate the fair value of an indefinite-lived intangible asset is more likely than not less than its carrying amount. As a result of the global economic disruption and uncertainty due to the COVID-19 pandemic, the Company concluded a triggering event had occurred as of March 31, 2020, and accordingly, performed interim impairment testing on certain indefinite-lived trade names. Based on these tests, it was determined that three of the Company's indefinite-lived trade names in the EMEA and Asia Pacific segments were impaired, and impairment charges of $8.2 million were recorded. Further intangible asset impairment charges were recorded in the Asia Pacific segment during the year ended December 31, 2020, including $2.6 million relating to supply chain disruptions, which reduced a brand's expected future cash flows, and $2.8 million related to declines in volumes and pricing pressure for a separate subsidiary in the region.

During the 2019 annual impairment testing, it was determined that two of the Company's indefinite-lived trade names were impaired, resulting in impairment charges totaling $5.9 million. No intangible asset impairment charges were recorded in 2018.

NOTE 7 - ACQUISITIONS

In December 2020, the Company acquired the remaining interest of Yonomi, Inc. ("Yonomi), a U.S. based smart home integration platform provider and innovation leader in IoT Cloud platforms, through one of its subsidiaries. Prior to acquisition, the Company held a noncontrolling interest in Yonomi that was considered an equity method investment. This acquisition has been accounted for as a business combination and did not have a material impact on the Consolidated Financial Statements. Yonomi has been integrated into the Americas segment.

In 2018, the Company completed six acquisitions:

Business	Date
Technical Glass Products, Inc. ("TGP")	January 2018
Hammond Enterprises, Inc. ("Hammond")	January 2018
Qatar Metal Industries LLC ("QMI")	February 2018
AD Systems, Inc. ("AD Systems")	March 2018
Gainsborough Hardware and API Locksmiths ("Door and Access Systems")	July 2018
ISONAS Security Systems, Inc. ("ISONAS")	July 2018

F-13

Total cash paid for the acquisitions completed in 2018 was approximately $373 million (net of cash acquired), including $4.6 million during the year ended December 31, 2019. These acquisitions were accounted for as business combinations.

During the years ended December 31, 2020, 2019 and 2018, the Company incurred $2.3 million, $2.0 million and $10.0 million, respectively, of acquisition and integration related expenses, which are included in Selling and administrative expenses in the Consolidated Statement of Comprehensive Income.

NOTE 8 - DIVESTITURES

As of December 31, 2020, the net assets of the Company's QMI business, which primarily included working capital and long-lived assets, met the criteria to be classified as held for sale, and accordingly, were written down to fair value, which was estimated based on expected sales proceeds, less cost to sell, in accordance with ASC 360. This remeasurement was based on inputs considered to be Level 3 inputs under the fair value hierarchy (see Note 13) and resulted in a Loss on assets held for sale of $37.9 million. As the expected sales proceeds, less cost to sell, were nominal, no goodwill was allocated to the Assets held for sale, and the goodwill attributable to the 2018 acquisition of QMI remains in the EMEA reporting unit as of December 31, 2020.

In 2019, the Company closed its production facility in Turkey and sold certain of the production assets thereof, which collectively met the definition of a business under ASC 805. Total proceeds from the sale were approximately $4.1 million, and the Company recorded a loss on divestiture of $24.2 million ($25.5 million, net of tax), primarily driven by the reclassification of $25.0 million of accumulated foreign currency translation adjustments to earnings upon sale. The Company also sold its interests in its Colombia operations in 2019 for a nominal amount, recording a net loss on divestiture of $5.9 million, of which $1.2 million relates to the reclassification of accumulated foreign currency translation adjustments to earnings upon sale. These losses are included within Loss on divestitures in the Consolidated Statements of Comprehensive Income.

NOTE 9 – DEBT AND CREDIT FACILITIES

At December 31, long-term debt and other borrowings consisted of the following:

Unsecured Credit Facilities

As of December 31, 2020, the Company has an unsecured Credit Agreement in place, consisting of a $700.0 million term loan facility (the “Term Facility”), of which $238.8 million is outstanding at December 31, 2020, and a $500.0 million revolving credit facility (the “Revolving Facility” and, together with the Term Facility, the “Credit Facilities”). The Credit Facilities mature on September 12, 2022, and are unconditionally guaranteed jointly and severally on an unsecured basis by the Company and Allegion US Holding Company Inc. ("Allegion US Hold Co"), the Company's wholly-owned subsidiary.

At inception, the Term Facility was scheduled to amortize in quarterly installments at the following rates: 1.25% per quarter starting December 31, 2017 through December 31, 2020, 2.5% per quarter from March 31, 2021 through June 30, 2022, with the balance due on September 12, 2022. Principal amounts repaid on the Term Facility may not be reborrowed. During the third quarter of 2019, the Company made a $400.0 million principal payment to partially pay down the outstanding Term Facility balance. As a result of this payment, the Company has satisfied its obligation to make quarterly installments on the Term Facility up to the maturity date, with the remaining outstanding balance due on September 12, 2022. In conjunction with this principal pay down, the Company recognized a $2.7 million charge related to the write-off of previously deferred financing

F-14

costs related to the Term Facility, which is included in Interest expense in the Consolidated Statement of Comprehensive Income for the year ended December 31, 2019.

The Revolving Facility provides aggregate commitments of up to $500.0 million, which includes up to $100.0 million for the issuance of letters of credit. At December 31, 2020, there were no borrowings outstanding on the Revolving Facility and the Company had $15.0 million of letters of credit outstanding. Commitments under the Revolving Facility may be reduced at any time without premium or penalty, and amounts repaid may be reborrowed. The Company pays certain fees with respect to the Revolving Facility, including an unused commitment fee on the undrawn portion of the Revolving Facility of between 0.125% and 0.200% per year, depending on the Company's credit rating, as well as certain other fees.

Outstanding borrowings under the Credit Facilities accrue interest at the option of the Company of (i) a LIBOR rate plus the applicable margin or (ii) a base rate plus the applicable margin. The applicable margin ranges from 1.125% to 1.500% depending on the Company's credit ratings. At December 31, 2020, the outstanding borrowings under the Term Facility accrue interest at LIBOR plus a margin of 1.250%, resulting in an interest rate of 1.51%. The Credit Facilities also contain negative and affirmative covenants and events of default that, among other things, limit or restrict the Company’s ability to enter into certain transactions. In addition, the Credit Facilities require the Company to comply with a maximum leverage ratio and a minimum interest expense coverage ratio, as defined within the agreement. As of December 31, 2020, the Company was in compliance with all covenants.

Senior Notes

As of December 31, 2020, Allegion US Hold Co has $400.0 million outstanding of its 3.200% Senior Notes due 2024 (the “3.200% Senior Notes”) and $400.0 million outstanding of its 3.550% Senior Notes due 2027 (the “3.550% Senior Notes”), while Allegion plc has $400.0 million outstanding of its 3.500% Senior Notes due 2029 (the “3.500% Senior Notes”). The 3.200% Senior Notes, 3.550% Senior Notes and 3.500% Senior Notes (collectively, the "Senior Notes") all require semi-annual interest payments on April 1 and October 1 of each year, and will mature on October 1, 2024, October 1, 2027, and October 1, 2029, respectively. The 3.200% Senior Notes and the 3.550% Senior Notes are senior unsecured obligations of Allegion US Hold Co and rank equally with all of Allegion US Hold Co’s existing and future senior unsecured and unsubordinated indebtedness. The guarantee of the 3.200% Senior Notes and the 3.550% Senior Notes is the senior unsecured obligation of the Company and ranks equally with all of the Company's existing and future senior unsecured and unsubordinated indebtedness. The 3.500% Senior Notes are senior unsecured obligations of Allegion plc, are guaranteed by Allegion US Hold Co and rank equally with all of the Company's existing and future senior unsecured indebtedness.

NOTE 10 – FINANCIAL INSTRUMENTS

In the normal course of business, the Company uses various financial instruments, including derivative instruments, to manage the risks associated with variable interest and currency rate exposures. These financial instruments are not used for trading or speculative purposes. When a derivative contract is entered into, the Company designates the derivative instrument as a cash flow hedge of a forecasted transaction, a cash flow hedge of a recognized asset or liability or as an undesignated derivative. The Company formally documents its hedge relationships, including identification of the derivative instruments and the hedged

F-15

items, as well as its risk management objectives and strategies for undertaking the hedge transaction. This process includes linking derivative instruments that are designated as hedges to specific assets, liabilities or forecasted transactions.

The Company assesses at inception and at least quarterly thereafter, whether the derivatives used in cash flow hedging transactions are effective in offsetting the changes in the cash flows of the hedged item. To the extent the derivative is deemed to be an effective hedge, the fair market value changes of the instrument are recorded to Accumulated other comprehensive loss, while changes in the fair market value of derivatives not deemed to be an effective hedge are recorded in Net earnings in the period of change. The fair market value of derivative instruments is determined through market-based valuations and may not be representative of the actual gains or losses that will be recorded when these instruments mature due to future fluctuations in the markets in which they are traded. If the hedging relationship ceases to be effective subsequent to inception, or it becomes probable that a forecasted transaction will longer occur, the hedging relationship will be undesignated and any future gains or losses on the derivative instrument will be recorded in Net earnings.

Currency Derivatives

The gross notional amount of the Company’s currency derivatives was $218.9 million and $146.4 million at December 31, 2020 and 2019, respectively. At December 31, 2020 and 2019, both the losses included in Accumulated other comprehensive loss and the amount expected to be reclassified into Net earnings over the next twelve months related to the Company’s currency derivatives designated as cash flow hedges were not material, although the actual amounts that will be reclassified to Net earnings may vary as a result of future changes in market conditions. Gains and losses associated with the Company’s currency derivatives not designated as hedges are recorded in Net earnings as changes in fair value occur. At December 31, 2020, the maximum term of the Company’s currency derivatives was less than one year.

Interest Rate Swaps

As of December 31, 2019, and through their expiration in September 2020, the Company had interest rate swaps to fix the interest rate paid during the contract period related to $200.0 million of the Company's variable rate Term Facility. Prior to expiration, these swaps met the criteria to be accounted for as cash flow hedges of variable rate interest payments.

The fair values of derivative instruments included within the Consolidated Balance Sheets as of December 31, 2020 and 2019 were not material. The amounts associated with derivatives designated as hedges affecting Net earnings and Accumulated other comprehensive loss for the years ended December 31 were as follows:

	Amount of gain (loss) recognized in Accumulated other comprehensive loss						Location of gain recognized in Net earnings	Amount of gain reclassified from Accumulated other comprehensive loss and recognized into Net earnings
In millions	2020		2019		2018			2020		2019		2018
Currency derivatives	$	4.1	$	1.9	$	4.3	Cost of goods sold	$	5.3	$	4.4	$	2.3
Interest rate swaps	(0.2)		(1.9)		2.5		Interest expense	0.5		3.1		2.2
Total	$	3.9	$	—	$	6.8		$	5.8	$	7.5	$	4.5

The gains and losses associated with the Company's non-designated currency derivatives, which are offset by changes in the fair value of the underlying transactions, are included within Other (income) expense, net in the Consolidated Statements of Comprehensive Income.

Concentration of Credit Risk

The counterparties to the Company’s forward contracts consist of a number of investment grade major international financial institutions. The Company could be exposed to losses in the event of nonperformance by the counterparties. However, the credit ratings and the concentration of risk in these financial institutions are monitored on a continuous basis and present no significant credit risk to the Company.

NOTE 11 - LEASES

The Company adopted ASC 842 on January 1, 2019, utilizing the transition method allowed per ASU 2018-11. Financial information for the year ended December 31, 2018, has not been adjusted for the effects of adopting ASC 842, and no cumulative-effect adjustment was required to the opening balance of Retained earnings on the adoption date. In accordance with ASC 842, the Company records a right-of-use ("ROU") asset and lease liability for substantially all leases for which it is a lessee. At inception of a contract, the Company considers all relevant facts and circumstances to assess whether or not the

F-16

contract represents a lease by determining whether or not the contract conveys the right to control the use of an identified asset, either explicit or implicit, for a period of time in exchange for consideration. The Company has no significant lease agreements in place for which the Company is a lessor, and substantially all of the Company's leases for which the Company is a lessee are classified as operating leases. Total rental expense for the years ended December 31, 2020 and 2019, was $44.2 million and $43.2 million, respectively, and is classified within Cost of goods sold and Selling and administrative expenses within the Consolidated Statements of Comprehensive Income. Rental expense related to short-term leases, variable lease payments or other leases or lease components not included within the ROU asset or lease liability totaled $9.1 million and $8.1 million, respectively, for the years ended December 31, 2020 and 2019. No material lease costs have been capitalized on the Consolidated Balance Sheets as of December 31, 2020 or 2019. Total rental expense for 2018, as determined in accordance with the previous lease guidance, ASC 840, was $42.5 million and is classified within Cost of goods sold and Selling and administrative expenses within the Consolidated Statements of Comprehensive Income.

If at lease commencement a lease has a term of less than 12 months and does not include a purchase option that is reasonably certain to be exercised, the Company does not include the lease as part of its ROU asset or lease liability. If the Company enters into a large number of leases in the same month with the same terms and conditions, these are considered a group (portfolio), assuming the lease model under this approach does not materially differ from applying ASC 842 to each individual lease. When available, the Company will utilize the rate implicit in the lease as the discount rate to determine the lease liability. However, as this rate is not available for most leases, the Company will use its incremental borrowing rate as the discount rate, which is the rate at inception of the lease the Company would hypothetically incur to borrow over a similar term the funds needed to purchase the leased asset.

As a lessee, the Company categorizes its leases into two general categories: real estate and equipment leases.

The Company’s real estate leases include leased production and assembly facilities, warehouses and distribution centers, office space and to a lesser degree, employee housing. The terms and conditions of real estate leases can vary significantly from lease to lease. The Company has assessed the specific terms and conditions of each real estate lease to determine the amount of the lease payments and the length of the lease term, which includes the minimum period over which lease payments are required plus any renewal options that are both within the Company's control to exercise and reasonably certain of being exercised upon lease commencement. The Company assesses all relevant factors to determine if sufficient incentives exist as of lease commencement to conclude whether or not renewal is reasonably certain. There are no material residual value guarantees provided by the Company nor any restrictions or covenants imposed by the real estate leases to which the Company is a party. In determining the lease liability, the Company utilizes its incremental borrowing rate for debt instruments with terms approximating the weighted-average term for its real estate leases to discount the future lease payments over the lease term to present value. The Company does incur variable lease payments for certain of its real estate leases, such as reimbursements of property taxes, maintenance and other operational costs to the lessor. In general, these variable lease payments are not captured as part of the lease liability or ROU asset, but rather are expensed as incurred.

The Company’s equipment leases include vehicles, material handling equipment, other machinery and equipment utilized in the Company's production and assembly facilities, warehouses and distribution centers, laptops and other IT equipment, and other miscellaneous leased equipment. Most of the equipment leases are for terms ranging from two to five years, although terms and conditions can vary from lease to lease. The Company applies similar estimates and judgments to its equipment lease portfolio in determining the lease payments and lease term as it does to its real estate lease portfolio. There are no material residual value guarantees provided by the Company nor any restrictions or covenants imposed by the equipment leases to which the Company is a party. In determining the lease liability, the Company utilizes its incremental borrowing rate for debt instruments with terms approximating the weighted-average term for its equipment leases to discount the future lease payments over the lease term to present value. The Company does not typically incur variable lease payments related to its equipment leases.

Amounts included within the Consolidated Balance Sheets related to the Company's ROU asset and lease liability were as follows:

The difference between the total undiscounted minimum lease payments and the combined current and noncurrent lease liabilities as of December 31, 2020, is due to imputed interest of $11.0 million.

NOTE 12 – PENSIONS AND POSTRETIREMENT BENEFITS OTHER THAN PENSIONS

The Company sponsors several U.S. defined benefit and defined contribution plans covering substantially all U.S. employees. Additionally, the Company has non-U.S. defined benefit and defined contribution plans covering eligible non-U.S. employees. Postretirement benefits, other than pensions, provide healthcare benefits, and in some instances, life insurance benefits for certain eligible employees.

F-18

Pension Plans

The noncontributory defined benefit pension plans covering non-collectively bargained U.S. employees provide benefits on an average pay formula, while most plans for collectively bargained U.S. employees provide benefits on a flat dollar benefit formula. The non-U.S. pension plans generally provide benefits based on earnings and years of service. The Company also maintains additional other supplemental plans for officers and other key employees.

The following table details information regarding the Company’s pension plans at December 31:

It is the Company’s objective to contribute to the pension plans to ensure adequate funds are available in the plans to make benefit payments to plan participants and beneficiaries when required. However, certain plans are not funded due to either legal, accounting or tax requirements in certain jurisdictions. As of December 31, 2020, approximately 6% of the Company's projected benefit obligation relates to plans that are not funded, of which the majority are non-U.S. plans.

The accumulated benefit obligation for all U.S. defined benefit pension plans was $354.9 million and $332.4 million at December 31, 2020 and 2019, respectively. The accumulated benefit obligation for all non-U.S. defined benefit pension plans was $446.0 million and $396.7 million at December 31, 2020 and 2019, respectively.

The Company estimates the service and interest cost components of net periodic benefit cost utilizing a full yield-curve approach. Under this approach, the Company applies discounting using the applicable spot rates derived from the yield curve to discount the cash flows used to measure the benefit obligation. These spot rates align to each of the projected benefit obligations and service cost cash flows.

Weighted-average assumptions used:

Net periodic pension cost for the year ended December 31,	2020		2019		2018
Discount rate:
U.S. plans	3.3	%	4.3	%	3.6	%

Expected return on plan assets:
U.S. plans	5.0	%	5.0	%	5.3	%
Non-U.S. plans	3.3	%	3.8	%	4.0	%

The expected return on plan assets reflects the average rate of returns expected on the funds invested or to be invested to provide for the benefits included in the projected benefit obligation and is based on what is achievable given the plan’s investment policy, the types of assets held and target asset allocations. The expected long-term rate of return is determined as of the measurement date. Each plan is reviewed, along with its historical returns and target asset allocations, to determine the appropriate expected return on plan assets to be used.

The Company's overall objective in managing defined benefit plan assets is to ensure that all present and future benefit obligations are met as they come due. The goal is to achieve this while trying to mitigate volatility in plan funded status, contributions and expense by better matching the characteristics of the plan assets to that of the plan liabilities. Each plan’s funded status and asset allocation is monitored regularly in addition to investment manager performance.

The Company's U.S. pension plan assets are valued using the following methodologies:

•Cash, cash equivalents and short-term investments – Short-term investments are valued at their daily net asset value (NAV) per share or the equivalent based upon the fair value of the underlying investments. NAV per share or the

F-22

equivalent is used for fair value purposes as a practical expedient and is calculated by the investment manager or sponsor of the fund. These investments primarily consist of short-term investment funds.

•Common collective trusts - Common collective trust ("CCT") funds are not publicly traded and are valued at NAV per share or the equivalent based upon the fair value of the underlying investments. NAV per share or the equivalent is used for fair value purposes as a practical expedient and is calculated by the investment manager or sponsor of the applicable fund. CCT funds consist of a variety of publicly traded securities, including equity mutual funds, U.S. government and agency obligations, corporate and non-U.S. bonds, securitized credit and emerging market debt. There are no unfunded commitments, redemption frequency restrictions or other redemption restrictions related to such investments.

The Company's non-U.S. pension plan assets are valued using the following methodologies:

•Cash, cash equivalents and short-term investments – Cash equivalents are valued using a market approach with inputs including quoted market prices for either identical or similar instruments. Short-term investments are valued at the closing price or amount held on deposit by the custodian bank, at fair value by discounting the related cash flows based on current yields of similar instruments with comparable durations considering the credit-worthiness of the issuer, or at their NAV per share or the equivalent based upon the fair value of the underlying investments. NAV per share or the equivalent is used for fair value purposes as a practical expedient and is calculated by the investment manager or sponsor of the fund. These investments primarily consist of short-term investment funds.

•Equity mutual funds – Equity mutual funds are primarily valued at their NAV per share or the equivalent. NAV per share or the equivalent is used for fair value purposes as a practical expedient. NAV is calculated by the investment manager or sponsor of the fund.

•Corporate and non-U.S. bonds – Quoted market prices are not available for these securities. Fair values are either estimated using pricing models and/or quoted prices of securities with similar characteristics or discounted cash flows, in which instances such securities are classified as Level 2 or valued at their NAV per share or the equivalent. NAV

F-23

per share or the equivalent is used for fair value purposes as a practical expedient and are calculated by the investment manager or sponsor of the fund.

The Company made employer contributions of $6.3 million, $6.0 million and $6.1 million to the U.S. pension plans in 2020, 2019 and 2018, respectively. The Company made required and discretionary contributions to its non-U.S. pension plans of $5.1 million, $10.6 million and $5.4 million in 2020, 2019 and 2018, respectively.

The Company currently projects that approximately $11.4 million will be contributed to its U.S and non-U.S. plans in 2021. The Company’s policy allows it to fund an amount, which could be in excess of or less than the pension cost expensed, subject to the limitations imposed by current tax regulations. The Company anticipates funding the plans in 2021 in accordance with contributions required by funding regulations or the laws of each jurisdiction.

Most of the Company’s U.S. employees are covered by defined contribution plans. Employer contributions are determined based on criteria specific to the individual plans and amounted to approximately $17.9 million, $15.6 million and $14.4 million in 2020, 2019 and 2018, respectively. The Company’s contributions relating to non-U.S. defined contribution plans and other non-U.S. benefit plans were $7.0 million, $6.0 million and $8.0 million in 2020, 2019 and 2018, respectively.

Deferred Compensation Plan

The Company maintains an Executive Deferred Compensation Plan ("EDCP"), which is an unfunded, nonqualified plan that, prior to 2019, permitted certain employees to defer up to 50% of their annual salary and up to 100% of their annual bonus awards, performance stock plan awards and restricted stock units earned until conclusion of their employment with the Company. As of December 31, 2020 and 2019, the deferred compensation liability balance was $18.1 million and $17.4 million, respectively, which was recorded within Postemployment and other benefit liabilities in the Consolidated Balance Sheets.

Postretirement Benefits Other Than Pensions

The Company sponsors a postretirement ("OPEB") plan that provides for healthcare benefits, and in some instances, life insurance benefits, that cover certain eligible retired employees. The Company funds postretirement benefit obligations principally on a pay-as-you-go basis. Generally, postretirement health benefits are contributory with contributions adjusted annually. Life insurance plans for retirees are primarily noncontributory. Net periodic postretirement benefit income is included within Other (income) expense, net within the Consolidated Statements of Comprehensive Income.

The benefit obligation related to the Company's postretirement plans as of December 31, 2020 and 2019 was $5.2 million and $6.8 million, respectively, and is classified as Accrued compensation and benefits and Postemployment and other benefit liabilities within the Consolidated Balance Sheets. Net periodic postretirement benefit income was not material for any of the years ended December 31, 2020, 2019 or 2018, nor is it projected to be material for 2021. Benefit payments for postretirement benefits, which are net of expected plan participant contributions and Medicare Part D subsidies, are expected to be less than $1 million per year for the foreseeable future.

NOTE 13 – FAIR VALUE MEASUREMENTS

Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value measurements are based on a framework that utilizes the inputs market participants use to determine the fair value of an asset or liability and establishes a fair value hierarchy to prioritize those inputs. The fair value hierarchy is comprised of the three levels described below:

•Level 1 – Inputs based on quoted prices in active markets for identical assets or liabilities.

•Level 2 – Inputs other than Level 1 quoted prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

•Level 3 – Unobservable inputs based on little or no market activity and that are significant to the fair value of the assets and liabilities.

The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs are obtained from independent sources and can be validated by a third

F-24

party, whereas unobservable inputs reflect assumptions regarding what a third party would use in pricing an asset or liability based on the best information available under the circumstances. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

Assets and liabilities measured at fair value at December 31, 2020, were as follows:

The Company determines the fair value of its financial assets and liabilities using the following methodologies:

•Investments – These instruments include equity mutual funds and corporate bond funds. The fair value is obtained based on observable market prices quoted on public exchanges for similar instruments.

•Derivative instruments – These instruments include foreign currency contracts for non-functional currency balance sheet exposures, including both those that are and are not designated as cash flow hedges. As of December 31, 2019, these instruments also included interest rate swap contracts, which expired in September 2020, related to the Company’s variable rate Term Facility. The fair value of the foreign currency contracts is determined based on a pricing model that uses spot rates and forward prices from actively quoted currency markets that are readily accessible and observable. The fair value of the interest rate swap contracts was determined based on quoted prices for the Company’s swaps, which was not considered an active market.

F-25

•Deferred compensation and other retirement plans - These include obligations related to deferred compensation and other retirement plans adjusted for market performance. The fair value is obtained based on observable market prices quoted on public exchanges for similar instruments.

•Debt – These instruments are recorded at cost and include senior notes maturing through 2029. The fair value of the long-term debt instruments is obtained based on observable market prices quoted on public exchanges for similar instruments.

The carrying values of Cash and cash equivalents, Restricted cash, Accounts and notes receivable, net, Accounts payable, Accrued compensation and benefits and Accrued expenses and other current liabilities are a reasonable estimate of their fair value due to the short-term nature of these instruments. As discussed in Note 2, the Company also has investments in debt and equity securities without readily determinable fair values, which are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer and are qualitatively assessed for impairment indicators at each reporting period. As these investments are considered to be nonrecurring fair value measurements, they are not included in the fair value tables above.

The methodologies used by the Company to determine the fair value of its financial assets and liabilities at December 31, 2020, are the same as those used at December 31, 2019.

NOTE 14 – EQUITY

In millions	Total
December 31, 2019	92.7
Shares issued under incentive plans	0.4
Repurchase of ordinary shares	(1.9)

(a)In February 2018, the FASB issued ASU 2018-02, "Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income," allowing entities to reclassify tax effects stranded in AOCI as a result of the 2017 U.S. Tax Cuts and Jobs Act (the "Tax Reform Act"). The Company adopted ASU 2018-02 in 2018, the impact of which is reflected in the reclassification presented above.

(b)During 2019, the Company reclassified $26.2 million of accumulated foreign currency translation adjustments to earnings upon the sale of the Company's business operations in Colombia and Turkey, which is included in Foreign currency items in the table above. See Note 8 for further information on these divestitures.

(c)During 2020, the Company reclassified $12.8 million of accumulated foreign currency translation adjustments to earnings upon the liquidation of two legal entities in EMEA, which is included in Foreign currency items in the table above.

All amounts of Other comprehensive income (loss), net attributable to noncontrolling interests on the Consolidated Statements of Equity relate to foreign currency items.

NOTE 15 – SHARE-BASED COMPENSATION

The Company records share-based compensation awards using a fair value method and recognizes compensation expense for an amount equal to the fair value of the share-based payment issued in its financial statements. The Company’s share-based compensation plans include programs for stock options, restricted stock units ("RSUs"), performance stock units ("PSUs") and deferred compensation.

Under the Company's incentive stock plan, the total number of ordinary shares authorized by the shareholders is 8.0 million, of which 2.9 million remain available as of December 31, 2020 for future incentive awards.

Compensation Expense

Share-based compensation expense is included in Cost of goods sold and Selling and administrative expenses within the Consolidated Statements of Comprehensive Income. The following table summarizes the expenses recognized for the years ended December 31:

In millions	2020		2019		2018
Stock options	$	3.8	$	3.5	$	4.3
RSUs	11.4		10.0		9.6
PSUs	5.6		6.9		5.7
Deferred compensation	2.4		3.2		(0.8)
Pre-tax expense	23.2		23.6		18.8
Tax benefit(a)	(2.9)		(3.0)		(1.9)
After-tax expense	$	20.3	$	20.6	$	16.9

(a)Tax benefit reflected in the table above does not include the excess benefit from exercises and vesting of share-based compensation of $4.5 million, $2.8 million and $1.5 million for the years ended December 31, 2020, 2019 and 2018, respectively.

Stock Options / RSUs

Eligible participants may receive (i) stock options, (ii) RSUs or (iii) a combination of both stock options and RSUs. The fair value of each of the Company’s stock option and RSU awards is expensed on a straight-line basis over the required service period, which is generally the 3-year vesting period. However, for stock options and RSUs granted to retirement eligible employees, the Company recognizes expense for the fair value at the grant date.

The average fair value of the stock options granted for the years ended December 31, 2020, 2019 and 2018, was estimated to be $25.62, $19.58 and $21.29 per share, respectively, using the Black-Scholes option-pricing model. The weighted-average assumptions used were as follows:

F-27

	2020		2019		2018
Dividend yield	0.99	%	1.23	%	0.97	%
Volatility	20.70	%	21.44	%	22.38	%
Risk-free rate of return	1.41	%	2.53	%	2.75	%
Expected life	6.0 years		6.0 years		6.0 years

Volatility is based on the Company's historic volatility for the prior six years. The risk-free rate of return is based on the yield curve of a zero-coupon U.S. Treasury bond on the date the award is granted with a maturity equal to the expected term of the award. The expected life of the Company’s stock option awards is derived from the simplified approach based on the weighted-average time to vest and the remaining contractual term and represents the period of time that awards are expected to be outstanding.

Changes in options outstanding under the plans for the years ended December 31, 2020, 2019 and 2018, were as follows:

	Shares subject to option	Weighted- average exercise price(a)		Aggregate intrinsic value (millions)		Weighted-average remaining life (years)

At December 31, 2020, there was $1.5 million of total unrecognized compensation cost from stock option arrangements granted under the plan, which is primarily related to unvested shares of non-retirement eligible employees. The aggregate intrinsic value of the Company's options exercised during the years ended December 31, 2020 and 2019, was $18.8 million and $16.3 million, respectively. Generally, stock options expire ten years from their date of grant.

(a)The weighted-average grant date fair value represents the fair value of the awards on the grant date converted to ordinary shares of the Company.

At December 31, 2020, there was $6.1 million of total unrecognized compensation cost from RSU arrangements granted under the plan, which is related to unvested shares of non-retirement eligible employees.

Performance Stock

The Company has a Performance Stock Program ("PSP") for key employees which provides awards in the form of PSUs based on performance against pre-established objectives. The annual target award level is expressed as a number of the Company's ordinary shares. All PSUs are settled in the form of ordinary shares unless deferred.

In February 2018, 2019 and 2020, the Company's Compensation Committee granted PSUs that were earned based 50% upon a performance condition, measured at each reporting period by earnings per share ("EPS") performance in relation to pre-established targets set by the Compensation Committee, and 50% upon a market condition, measured by the Company’s relative total shareholder return ("TSR") against the S&P 400 Capital Goods Index over a three-year performance period. The fair values of the market conditions are estimated using a Monte Carlo simulation approach in a risk-neutral framework to model future stock price movements based upon historical volatility, risk-free rates of return and correlation matrix.

F-29

The following table summarizes PSU activity for the maximum number of shares that may be issued for the years ended December 31, 2020, 2019 and 2018:

	PSUs	Weighted-average grant date fair value(a)

Outstanding and unvested at December 31, 2020	145,976	$	93.89

(a)The weighted-average grant date fair value represents the fair value of the awards on the grant date converted to ordinary shares of the Company.

At December 31, 2020, there was $4.6 million of total unrecognized compensation cost from the PSP based on current performance, which is related to unvested shares. This compensation will be recognized over the required service period, which is generally the three-year vesting period.

Deferred Compensation

Prior to 2019, the Company allowed key employees to defer a portion of their eligible granted PSUs and/or compensation into a number of investment choices including its ordinary share equivalents. Any amounts invested in ordinary share equivalents will be settled in ordinary shares of the Company at the time of distribution.

NOTE 16 – RESTRUCTURING ACTIVITIES

Restructuring charges recorded during the years ended December 31 associated with restructuring activities were follows:

In millions	2020		2019		2018
Americas	$	5.5	$	1.4	$	0.5
EMEA	12.4		13.4		3.3

Selling and administrative expenses	20.4		6.3		3.2
Total	$	25.6	$	14.6	$	4.9

Restructuring charges across all regions are primarily related to workforce reductions intended to optimize and simplify operations and cost structure. Restructuring charges in EMEA also included costs related to the closure of the Company's production facility in Turkey in 2019. Approximately $1.9 million of the 2019 restructuring charges related to pension curtailment costs, which are included within Other (income) expense, net within the Consolidated Statements of Comprehensive Income.

The changes in the restructuring reserve during the years ended December 31, 2020 and 2019, were as follows:

The majority of the costs accrued as of December 31, 2020, will be paid within one year.

The Company also incurred other non-qualified restructuring charges of $1.2 million, $5.7 million and $1.6 million during the years ended December 31, 2020, 2019 and 2018, respectively, which represent costs directly attributable to restructuring activities, but that do not fall into the severance, exit or disposal category. Approximately $4.3 million of the non-qualified restructuring expenses incurred during 2019 related to the closure of the Company's production facility in Turkey. Non-qualified restructuring charges are included within Cost of goods sold and Selling and administrative expenses within the Consolidated Statements of Comprehensive Income.

The Company anticipates additional future restructuring charges of approximately $5 to $10 million related to certain of the restructuring actions initiated during the year ended December 31, 2020, primarily across several businesses and functions intended to optimize and simplify the Company's non-U.S. operations and cost structure. These future costs are expected to be cash expenditures and classified as both qualified and non-qualified restructuring. These costs are expected to be incurred within fiscal year 2021.

NOTE 17 – OTHER (INCOME) EXPENSE, NET

At December 31, the components of Other (income) expense, net were as follows:

(1)Net of changes in valuation allowances

On December 22, 2017, the Tax Reform Act became law, resulting in broad and complex changes to the U.S. tax code. The impact to the Company's Consolidated Financial Statements during the year ended December 31, 2017, included, but were not limited to, a (1) reduced U.S. federal corporate tax rate from 35.0% to 21.0%, effective January 1, 2018, (2) required a one-time transition tax on certain unrepatriated earnings of non-U.S. subsidiaries and (3) required review of the future realizability of deferred tax balances.

Shortly after the Tax Reform Act was enacted, the SEC staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (SAB 118) which provided guidance on accounting for the Tax Reform Act’s impact. SAB 118 provided a measurement period, which in no case was to extend beyond one year from the Tax Reform Act enactment date, during which a company acting in good faith could complete the accounting for the impacts of the Tax Reform Act under ASC Topic 740. In finalizing the net tax charge resulting from the Tax Reform Act, in accordance with the one-year SAB 118 measurement period, the Company reversed $22.8 million of previous charges and recorded an additional $0.9 million of transition tax in 2018.

The majority of the Company's earnings are considered permanently reinvested, and therefore, the Company has not recorded any incremental withholding or income tax liabilities on earnings of its non-U.S. subsidiaries.

At December 31, a summary of the deferred tax accounts was as follows:

In millions	2020		2019
Deferred tax assets:

Net deferred tax assets	$	58.1	$	43.3

At December 31, 2020, $1.4 million of deferred taxes were recorded for certain undistributed earnings of non-U.S. subsidiaries. Historically, no deferred taxes have been provided for any portion of the remaining undistributed earnings of the Company's subsidiaries since these earnings have been, and will continue to be, permanently reinvested in these subsidiaries. For many reasons, including the number of legal entities and jurisdictions involved, the complexity of the Company's legal entity structure, the complexity of tax laws in the relevant jurisdictions and the impact of projections of income for future years to any calculations, the Company believes it is not practicable to estimate, within any reasonable range, the amount of additional taxes which may be payable upon the distribution of earnings.

At December 31, 2020, the Company had the following tax losses and tax credit carryforwards available to offset taxable income in prior and future years:

In millions	Amount		Expiration Period
U.S. Federal tax loss carryforwards	$	18.9	2027-2037
U.S. Federal and State credit carryforwards	22.5		2025-2037
U.S. State tax loss carryforwards	22.9		2021-Unlimited
Non-U.S. tax loss carryforwards	$	1,015.8	2021-Unlimited

The U.S. state loss carryforwards were incurred in various jurisdictions. The non-U.S. loss carryforwards were incurred in various jurisdictions, predominantly in China, Ireland, Italy, Luxembourg and the United Kingdom.

The Company evaluates its deferred income tax assets to determine if valuation allowances are required or should be adjusted. GAAP requires that companies assess whether valuation allowances should be established against their deferred tax assets based on consideration of all available evidence, both positive and negative, using a "more likely than not" standard. This assessment considers the nature, frequency and amount of recent losses, the duration of statutory carryforward periods and tax planning strategies. In making such judgments, significant weight is given to evidence that can be objectively verified.

F-33

Activity associated with the Company’s valuation allowance is as follows:

In millions	2020		2019		2018
Beginning balance	$	241.0	$	357.1	$	312.9
Increase to valuation allowance	21.1		2.8		70.9
Decrease to valuation allowance	(2.8)		(118.6)		(25.0)
Foreign exchange translation	0.4		(0.3)		(1.7)
Ending balance	$	259.7	$	241.0	$	357.1

During the year ended December 31, 2020, the valuation allowance increased by $18.7 million, while during the year ended December 31, 2019, the valuation allowance decreased by $116.1 million. The increase for the year ended December 31, 2020, and the decrease for the year ended December 31, 2019, are the result of changes in country specific tax laws, internal restructurings, jurisdictional profitability and changes in judgments and facts regarding the realizability of deferred tax assets.

The Company has total unrecognized tax benefits of $41.2 million and $37.3 million as of December 31, 2020 and 2019, respectively. The amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is $41.2 million as of December 31, 2020. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

The Company records interest and penalties associated with the uncertain tax positions within its provision for income taxes. The Company had reserves associated with interest and penalties, net of tax, of $7.6 million and $6.2 million at December 31, 2020 and 2019, respectively. For the years ended December 31, 2020 and 2019, the Company recognized $1.9 million and $1.3 million in net interest and penalties, net of tax, related to these uncertain tax positions.

The total amount of unrecognized tax benefits relating to the Company's tax positions is subject to change based on future events including, but not limited to, the settlements of ongoing audits and/or the expiration of applicable statutes of limitations. Although the outcomes and timing of such events are highly uncertain, it is reasonably possible that the balance of gross unrecognized tax benefits, excluding interest and penalties, could potentially be reduced by up to approximately $14.8 million during the next 12 months.

The provision for income taxes involves a significant amount of management judgment regarding interpretation of relevant facts and laws in the jurisdictions in which the Company operates. Future changes in applicable laws, projected levels of taxable income and tax planning could change the effective tax rate and tax balances recorded by the Company. In addition, tax authorities periodically review income tax returns filed by the Company and can raise issues regarding its filing positions, timing and amount of income or deductions and the allocation of income among the jurisdictions in which the Company operates. A significant period of time may elapse between the filing of an income tax return and the ultimate resolution of an issue raised by a tax authority with respect to that return. In the normal course of business, the Company is subject to examination by taxing authorities throughout the world, including such major jurisdictions as Australia, Canada, France, Germany, Italy, Mexico, the Netherlands and the U.S. In general, the examination of the material tax returns of subsidiaries of the Company is complete for the years prior to 2003, with certain matters being resolved through appeals and litigation.

NOTE 19 – EARNINGS PER SHARE (EPS)

Basic EPS is calculated by dividing Net earnings attributable to Allegion plc by the weighted-average number of ordinary shares outstanding for the applicable period. Diluted EPS is calculated after adjusting the denominator of the basic EPS calculation for the effect of all potentially dilutive ordinary shares, which in the Company’s case, includes shares issuable under share-based compensation plans.

F-34

The following table summarizes the weighted-average number of ordinary shares outstanding for basic and diluted earnings per share calculations:

In millions	2020	2019	2018
Weighted-average number of basic shares	92.3	93.6	95.0
Shares issuable under share-based compensation plans	0.5	0.7	0.7
Weighted-average number of diluted shares	92.8	94.3	95.7

At December 31, 2020, 0.1 million stock options were excluded from the computation of weighted-average diluted shares outstanding because the effect of including these shares would have been anti-dilutive.

NOTE 20 – NET REVENUES

Net revenues are recognized based on the satisfaction of performance obligations under the terms of a contract. A performance obligation is a promise in a contract to transfer control of a distinct product or to provide a service, or a bundle of products or services, to a customer. The Company has two principal revenue streams, tangible product sales and services. Approximately 99% of consolidated Net revenues involve contracts with a single performance obligation, the transfer of control of a product or bundle of products to a customer. Transfer of control typically occurs when goods are shipped from the Company's facilities or at other predetermined control transfer points (for instance, destination terms). Net revenues are measured as the amount of consideration expected to be received in exchange for transferring control of the products and takes into account variable consideration, such as sales incentive programs including discounts and volume rebates. The existence of these programs does not preclude revenue recognition but does require the Company's best estimate of the variable consideration to be made based on expected activity, as these items are reserved for as a deduction to Net revenues over time based on the Company's historical rates of providing these incentives and annual forecasted sales volumes. The Company also offers a standard warranty with most product sales and the value of such warranty is included in the contractual price. The corresponding cost of the warranty obligation is accrued as a liability (see Note 21).

The Company's remaining Net revenues involve services, including installation and consulting. Unlike the single performance obligation to ship a product or bundle of products, revenue recognition related to services revenues is delayed until the service based performance obligations are satisfied. In some instances, customer acceptance provisions are included in sales arrangements to give the buyer the ability to ensure the service meets any established criteria. In these instances, revenue recognition is deferred until the performance obligations are satisfied, which could include acceptance terms specified in the arrangement being fulfilled through customer acceptance or a demonstration that established criteria have been satisfied. During the years ended December 31, 2020 and 2019, no adjustments related to performance obligations satisfied in previous periods were recorded.

The Company applies the practical expedients allowed under ASC 606 to omit the disclosure of remaining performance obligations for contracts with an original expected duration of one year or less and for contracts where the Company has the right to invoice for performance completed to date. The transaction price is not adjusted for the effects of a significant financing component, as the time period between control transfer of goods and services is less than one year. Sales, value-added and other similar taxes collected by the Company are excluded from Net revenues. The Company has also elected to account for shipping and handling activities that occur after control of the related goods transfers as fulfillment activities instead of performance obligations. These activities are included in Cost of goods sold in the Consolidated Statements of Comprehensive Income. The Company’s payment terms are generally consistent with the industries in which its businesses operate.

The following table shows the Company's Net revenues related to both tangible product sales and services for the years ended December 31, 2020, 2019 and 2018, respectively, disaggregated by business segment. Net revenues are shown by tangible product sales and services, as contract terms, conditions and economic factors affecting the nature, amount, timing and uncertainty around revenue recognition and cash flows are substantially similar within each of the two principal revenue streams:

As of December 31, 2020 and 2019, neither the contract assets related to the Company's right to consideration for work completed but not billed nor the contract liabilities associated with contract revenue were material. As a practical expedient, the Company recognizes incremental costs of obtaining a contract, if any, as an expense when incurred if the amortization period of the asset would have been one year or less. The Company does not have any costs to obtain or fulfill a contract that are capitalized under ASC 606.

NOTE 21 – COMMITMENTS AND CONTINGENCIES

The Company is involved in various litigation, claims and administrative proceedings, including those related to environmental and product warranty matters. Amounts recorded for identified contingent liabilities are estimates, which are reviewed periodically and adjusted to reflect additional information when it becomes available. Subject to the uncertainties inherent in estimating future costs for contingent liabilities, except as expressly set forth in this note, management believes that any liability which may result from these legal matters would not have a material adverse effect on the financial condition, results of operations, liquidity or cash flows of the Company.

Environmental Matters

The Company is dedicated to an environmental program to reduce the utilization and generation of hazardous materials during the manufacturing process and to remediate identified environmental concerns. As to the latter, the Company is currently engaged in site investigations and remediation activities to address environmental cleanup from past operations at current and former production facilities. The Company regularly evaluates its remediation programs and considers alternative remediation methods that are in addition to, or in replacement of, those currently utilized by the Company based upon enhanced technology and regulatory changes. Changes to the Company's remediation programs may result in increased expenses and increased environmental reserves.

The Company is sometimes a party to environmental lawsuits and claims and has, from time to time, received notices of potential violations of environmental laws and regulations from the U.S. Environmental Protection Agency and similar state authorities. It has also been identified as a potentially responsible party ("PRP") for cleanup costs associated with off-site waste disposal at federal Superfund and state remediation sites. For all such sites, there are other PRPs and, in most instances, the Company’s involvement is minimal.

In estimating its liability, the Company has assumed it will not bear the entire cost of remediation of any site to the exclusion of other PRPs who may be jointly and severally liable. The ability of other PRPs to participate has been taken into account, based on the Company's understanding of the parties’ financial condition and probable contributions on a per site basis. Additional lawsuits and claims involving environmental matters are likely to arise from time to time in the future.

The Company incurred $7.1 million, $1.7 million and $2.4 million of expenses during the years ended December 31, 2020, 2019 and 2018, respectively, for environmental remediation at sites presently or formerly owned or leased by the Company. Environmental remediation costs are recorded in Costs of goods sold within the Consolidated Statements of Comprehensive Income.

As of December 31, 2020 and 2019, the Company has recorded reserves for environmental matters of $21.1 million and $19.3 million, respectively. The total reserve at December 31, 2020 and 2019, included $4.4 million and $4.2 million, respectively, related to remediation of sites previously disposed by the Company. Environmental reserves are classified as Accrued expenses and other current liabilities or Other noncurrent liabilities within the Consolidated Balance Sheets based on the timing of their expected future payment. The Company's total current environmental reserve at December 31, 2020 and 2019, was $6.1 million

F-36

and $6.2 million, respectively, and the remainder is classified as noncurrent. Given the evolving nature of environmental laws, regulations and technology, the ultimate cost of future compliance is uncertain.

Warranty Liability

Standard product warranty accruals are recorded at the time of sale and are estimated based upon product warranty terms and historical experience. The Company assesses the adequacy of its liabilities and will make adjustments as necessary based on known or anticipated warranty claims, or as new information becomes available.

The changes in the standard product warranty liability for the years ended December 31, were as follows:

In millions	2020		2019		2018
Balance at beginning of period	$	15.9	$	14.5	$	14.1
Reductions for payments	(7.3)		(8.4)		(7.9)
Accruals for warranties issued during the current period	8.2		10.3		7.8
Changes to accruals related to preexisting warranties	(0.6)		(0.4)		0.2
Acquisitions	—		—		0.5
Translation	0.3		(0.1)		(0.2)
Balance at end of period	$	16.5	$	15.9	$	14.5

Standard product warranty liabilities are classified as Accrued expenses and other current liabilities or Other noncurrent liabilities within the Consolidated Balance Sheets based on the timing of the expected future payments.

NOTE 22 – BUSINESS SEGMENT INFORMATION

The Company classifies its business into the following three reportable segments based on industry and market focus: Americas; Europe, Middle East and Africa ("EMEA"); and Asia Pacific. Results for the Company's India operations are now included within the Asia Pacific segment results due to an operational change during the year ended December 31, 2020. This change did not result, and is not expected to result, in a material impact to Segment results of operations for either the EMEA or Asia Pacific segment.

The Company largely evaluates performance based on Segment operating income and Segment operating margins. Segment operating income is the measure of profit and loss that the Company’s chief operating decision maker uses to evaluate the financial performance of the business and as the basis for resource allocation, performance reviews and compensation. For these reasons, the Company believes that Segment operating income represents the most relevant measure of segment profit and loss. The Company’s chief operating decision maker may exclude certain charges or gains, such as corporate charges and other special charges, from Operating income to arrive at a Segment operating income that is a more meaningful measure of profit and loss upon which to base operating decisions. The Company defines Segment operating margin as Segment operating income as a percentage of the segment's Net revenues.

ALLEGION PLC

INCENTIVE STOCK PLAN OF 2013

GLOBAL RESTRICTED STOCK UNIT AWARD AGREEMENT

DATED AS OF [GRANT DATE] ("GRANT DATE")

Allegion plc (the “Company”) hereby grants to [insert name] (“Participant”) a restricted stock unit award (the “RSUs”) with respect to [insert number of shares subject to RSUs] ordinary shares of the Company (the “Shares”), pursuant to and subject to the terms and conditions set forth in the Company’s Incentive Stock Plan of 2013 (the “Plan”) and to the terms and conditions set forth in this Restricted Stock Unit Award Agreement (the “Award Agreement”), including any appendix to the Award Agreement for Participant’s country (the “Appendix”). Unless otherwise defined herein, the terms defined in the Plan shall have the same meanings in this Award Agreement.

1.Vesting Schedule.

Participant’s right to receive Shares subject to the RSUs shall vest in accordance with the table below (each date being a “Vesting Date”), subject to Participant’s continued employment with the Company or an Affiliate on each Vesting Date unless otherwise specified in Section 3.

[Vesting Table: quantity, Month DD, YYYY]

2.Dividend Equivalents.

Participant shall be entitled to receive an amount equal to any cash dividend paid by the Company upon one Share for each RSU held by Participant when such dividend is paid (“Dividend Equivalent”), provided that, (i) Participant shall have no right to receive the Dividend Equivalents unless and until the associated RSUs vest, (ii) Dividend Equivalents shall not accrue interest and (iii) Dividend Equivalents shall be paid in cash at the time that the associated RSUs vest.

3.Termination of Employment.

(a)Group Termination

If Participant’s employment terminates involuntarily by reason of a group termination (including, but not limited to, terminations resulting from sale of a business or division, outsourcing of an entire function, reduction in workforce or closing of a facility) (a “Group Termination Event”), the number of Shares subject to the RSUs that would have vested within 12 months of termination of Participant’s active employment shall vest as of the date of termination of active employment (such date also being a “Vesting Date”) and all other RSUs and associated Dividend Equivalents shall be forfeited as of the date of termination of active employment, and Participant shall have no right to or interest in such RSUs, the underlying Shares or any associated Dividend Equivalents.

(b)Termination Due to Disability

If Participant’s employment terminates by reason of Disability, the Shares subject to the RSUs t

hat have not yet vested shall vest as of the date of such termination of employment (such date also being a “Vesting Date”). For purposes of this Section 3(b), “Disability” shall mean a disability determined under the long-term disability plan maintained by the Company under which Participant is covered, or, in the event no such plan exists or Participant is not covered under any such plan, a total and permanent disability pursuant to the Employer’s human resources determination.

(c)Termination Due to Retirement

Notwithstanding the provisions of Section 3(a) and (b) above, and unless Participant’s employment terminates for Cause, if Participant’s employment terminates after attainment of age 55 with at least 5 years of service (“Retirement”), the Shares subject to the RSUs shall continue to vest according to the schedule set forth in Section 1, notwithstanding such termination of employment.

(d)Termination Due to Death

Notwithstanding the provisions of Section 3(c) above, if Participant’s employment terminates due to death, the Shares subject to the RSUs that have not yet vested shall vest as of the date of such termination of employment (such date also being a “Vesting Date”).

If Participant’s employment terminates (i) for any reason or in any circumstances other than those specified in Section 3(a) through (d) above or (ii) for Cause, all unvested RSUs and associated Dividend Equivalents shall be forfeited as of the date of termination of active employment and Participant shall have no right to or interest in such RSUs, the underlying Shares or any associated Dividend Equivalents.

4.Settlement.

(a)General

On or as soon as administratively practicable (and any event within 30 days) following each Vesting Date, the Company shall cause to be issued to Participant Shares with respect to the RSUs that become vested on such Vesting Date.Notwithstanding the foregoing, if Participant is subject to U.S. federal income tax on any part of the payment of the RSUs and the RSUs are considered non-qualified deferred compensation subject to Section 409A of the Code, the RSUs shall be settled within 30 days of the earliest to occur of the following dates or events, subject to any delay required by Section 4(b) below: (i) the Vesting Dates set forth in Section 1 in the case of RSUs that vest pursuant to Section 1 or 3(c), (ii) a “separation from service” within the meaning of Section 409A of the Code in the case of RSUs that vest pursuant Section 3(a), 3(b) and 3(d) above and Section 9(b)(iv)(D) of the Plan and (iii) a “change in control event” within the meaning of U.S. Treasury Regulation §1.409A-3(i)(5) in the case of RSUs that vest pursuant to Section 9(b) of the Plan.Such Shares shall be fully paid and non-assessable.Participant will not have any of the rights or privileges of a shareholder of the Company in respect of any Shares subject to the RSUs unless and until such Shares have been issued to Participant.

(b)Delayed Payment

Notwithstanding Section 4(a) above, if the RSUs are considered an item of deferred compensation under Section 409A of the Code and the Shares are distributable by reason of a Participant’s separation from service during the period that Participant is both subject to U.S. federal income taxation and a “specified employee” (within the meaning of Section 409A(a)(2)(B)(i) of the Code), any Shares that would otherwise be issuable during the 6-month period immediately following Participant’s separation from service will be issued on the first day of the 7th month following Participant’s separation from service (or, if Participant dies during such period, within 30 days after Participant’s death).

5.Change in Control.

In the event of a Change in Control, the treatment of the RSUs will be governed by the terms of the Plan, subject to Section 4 above.

6.Responsibility for Taxes.

Participant acknowledges that, regardless of any action taken by the Company or, if different, Participant’s employer (the “Employer”), the ultimate liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to Participant’s participation in the Plan and legally applicable to Participant (“Tax-Related Items”) is and remains Participant’s responsibility and may exceed the amount (if any) actually withheld by the Company or the Employer.Participant further acknowledges that the Company and the Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the RSUs; and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the RSUs to reduce or eliminate Participant’s liability for Tax-Related Items or achieve any particular tax result.Further, if Participant is subject to Tax‑Related Items in more than one jurisdiction, Participant acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

To satisfy any withholding obligations of the Company and/or the Employer with respect to Tax-Related Items (other than U.S. Federal Insurance Contribution Act taxes or other Tax-Related Items which become payable in a year prior to the year in which the Shares are issued pursuant to the RSUs, and other than Tax-Related Items due on Dividend Equivalents), the Company will withhold Shares otherwise issuable upon settlement of the RSUs.Alternatively, or in addition, in connection with any applicable taxable or tax withholding event, Participant authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy their obligations (if any) with regard to all Tax-Related Items by one or a combination of the following:

(a)withholding from Participant’s wages or other cash compensation payable to Participant by the Company or the Employer;

(b)withholding from proceeds of the sale of Shares acquired upon settlement of the RSUs either through a voluntary sale or through a mandatory sale arranged by the Company (on Participant’s behalf pursuant to this authorization without further consent);

(c)requiring Participant to tender a cash payment to the Company or an Affiliate in the amount of the Tax-Related Items; and/or

(d)any other method of withholding determined by the Company to be permitted under the Plan and, to the extent required by applicable law or the Plan, approved by the Committee;

provided, however, that if Participant is a Section 16 officer of the Company under the Act, the withholding methods described in this Section 6 (a) through (d) will only be used if the Committee (as constituted to satisfy Rule 16b-3 of the Act) determines, in advance of the applicable withholding event, that one such withholding method will be used in lieu of withholding Shares.

The Company may withhold for Tax-Related Items by considering minimum statutory withholding rates or other withholding rates, including maximum withholding rates applicable in Participant’s jurisdiction(s). In the event of over-withholding, Participant may receive a refund of any over-withheld

amount in cash (with no entitlement to the equivalent amount in Shares) from the Company or the Employer; otherwise, Participant may be able to seek a refund from the local tax authority.In the event of under-withholding, Participant may be required to pay any additional Tax-Related Items directly to the applicable tax authority.If the obligation for Tax-Related Items is satisfied by withholding Shares, for tax purposes, Participant is deemed to have been issued the full number of Shares subject to the vested portion of the RSUs, notwithstanding that a number of the Shares are held back solely for the purpose of paying the Tax-Related Items.The Company may refuse to issue or deliver the Shares or the proceeds of the sale of Shares, if Participant fails to comply with his or her obligations in connection with the Tax-Related Items.

7.Nature of Grant.

In accepting the RSUs, Participant acknowledges, understands and agrees that:

(a)the Plan is established voluntarily by the Company, it is discretionary in nature and it may be amended, altered or discontinued by the Company at any time, to the extent permitted by the Plan;

(b)the grant of the RSUs is voluntary and occasional and does not create any contractual or other right to receive future grants of restricted stock units, or benefits in lieu of restricted stock units, even if restricted stock units have been granted in the past;

(c)all decisions with respect to future restricted stock unit grants, if any, will be at the sole discretion of the Company;

(d)Participant is voluntarily participating in the Plan;

(e)the RSUs and the Shares subject to the RSUs, and the income and value of same, are not intended to replace any pension rights or compensation;

(f)the RSUs and the Shares subject to the RSUs, and the income and value of same,are not part of normal or expected compensation or salary for any purpose, including, but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end of service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments;

(g)unless otherwise agreed with the Company, the RSUs and the Shares subject to the RSUs, and the income and value of same, are not granted as consideration for, or in connection with, services Participant may provide as a director of an Affiliate;

(h)the RSU grant and Participant’s participation in the Plan will not create a right to employment or be interpreted as forming or amending an employment or service contract with the Company, the Employer or any Affiliate and will not interfere with the ability of the Company, the Employer or any Affiliate, as applicable, to terminate Participant’s employment or service relationship (if any);

(i)the future value of the underlying Shares is unknown, indeterminable and cannot be predicted with certainty;

(j)no claim or entitlement to compensation or damages shall arise from forfeiture of the RSUs resulting from Participant ceasing to provide employment or other services to the Company or the Employer (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Participant is employed or the terms of Participant’s employment agreement, if any) or from cancellation of the RSUs or recoupment of any financial gain resulting from the RSUs as described in Section 14 below;

(k)for purposes of the RSUs, Participant’s employment or other service relationship will be considered terminated as of the date Participant is no longer actively providing services to the Company or one of its Affiliates (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Participant is employed or the terms of Participant’s employment agreement, if any) and, unless otherwise expressly provided in this Award Agreement or determined by the Company, Participant’s right to vest in the RSUs under the Plan, if any, will terminate as of such date, or will be measured with reference to such date in the case of a Group Termination Event, Retirement or termination due to Disability or death, and will not be extended by any notice period (e.g., Participant’s period of active service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where Participant is employed or the terms of Participant’s employment agreement, if any); the Committee shall have the exclusive discretion to determine when Participant is no longer actively providing services for purposes of the RSUs (including whether Participant may still be considered to be providing services while on a leave of absence);

(m)neither the Company, nor the Employer nor any Affiliate will be liable for any foreign exchange rate fluctuation between Participant’s local currency and the United States Dollar that may affect the value of the RSUs or of any amounts due to Participant pursuant to the settlement of the RSUs or the subsequent sale of any Shares acquired upon settlement.

8.No Advice Regarding Grant.

The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding Participant’s participation in the Plan, or his or her acquisition or sale of the underlying Shares.Participant should consult with his or her own personal tax, legal and financial advisors regarding Participant’s participation in the Plan before taking any action related to the Plan.

9.Data Privacy.

(a)Data Collection and Usage.The Company and the Employer may collect, process and use certain personal information about Participant, including, but not limited to, Participant’s name, home address and telephone number, email address, date of birth, social insurance number, passport or other identification number, salary, nationality, job title, any shares or directorships held in the Company, details of all RSUs granted under the Plan or any other entitlement to shares awarded, canceled, exercised, vested, unvested or outstanding in Participant’s favor (“Data”), for the purposes of implementing, administering and managing the Plan.The Company, with its registered address at

Block D, Iveagh Court, Harcourt Road, Dublin 2, Ireland, acts as the data controller in respect of such Data.

For Participants in the European Union / European Economic Area / Switzerland / United Kingdom (“EEA+”), the legal basis for the processing of Data is that it is necessary for the performance of the Company's contractual obligation to deliver Shares (if the conditions of the Plan and the Award Agreement are satisfied) and, generally, to manage and administer Participant's participation in the Plan.

For Participants outside the EEA+, the legal basis for the processing of Data is Participant’s consent.

(b)Stock Plan Administration Service Providers. The Company transfers Data to UBS, Broadridge Output Solutions, Inc., Cognizant Worldwide Limited, DG3, HCL Technologies Limited, Iron Mountain, and Solium Capital, which assist the Company with the implementation, administration and management of the Plan.In the future, the Company may select different service providers share Data with such other providers serving in a similar manner.Participant may be asked to acknowledge or (where applicable) agree to separate terms and data processing practices with the service providers, with such agreement (where applicable) being a condition to the ability to participate in the Plan.

(c)International Data Transfers.The Company and its service providers are based in the United States.Participant’s country or jurisdiction may have different data privacy laws and protections than the United States.

For Participants in the EEA+, the legal basis for the transfer of Data is that it is necessary for the performance of the Company's contractual obligation to deliver Shares (if the conditions of the Plan and the Award Agreement are satisfied) and, generally, to manage and administer Participant's participation in the Plan.

For Participants outside the EEA+, the legal basis for the transfer of Data is Participant’s consent.

(d)Data Retention.The Company will hold and use Data only as long as is necessary to implement, administer and manage Participant’s participation in the Plan, or as required to comply with legal or regulatory obligations, including under tax, exchange control, labor and securities laws.This may extend beyond Participant’s period of employment with the Company or the Employer.

(e)Data Subject Rights.Participant may have a number of rights under the data privacy laws in his or her jurisdiction.Depending on where Participant is based, such rights may include the right to (i) request access or copies of Data the Company processes, (ii) rectification of incorrect Data, (iii) deletion of Data, (iv) restrictions on processing of Data, (v) portability of Data, (vi) lodge complaints with competent authorities in Participant’s jurisdiction, and/or (vii) receive a list with the names and addresses of any potential recipients of Data.To receive clarification regarding these rights or to exercise these rights, Participant understands that he or she can contactDataprivacy@Allegion.com.

(f)Declaration of Consent (for Participants outside the EEA+ Only).By accepting this award of RSUs and indicating consent via the Company’s online acceptance procedure, Participant is declaring that he or she agrees with the data processing practices described herein and consents to the collection, processing and use of Data by the Company and the transfer of Data to the recipients

mentioned herein, including recipients located in countries which may not have a similar level of protection from the perspective of the data protection laws in Participant’s country.

Participation in the Plan is voluntary and Participant is providing the consents described herein on a purely voluntary basis.If Participant does not consent, or if Participant later seeks to revoke his or her consent, Participant’s salary from or employment and career with the Employer will not be affected; the only consequence of refusing or withdrawing consent is that the Company would not be able to grant RSUs under the Plan to Participant or administer or maintain Participant’s participation in the Plan.

10.Electronic Delivery and Participation.

The Company may, in its sole discretion, decide to deliver any documents related to participation in the Plan by electronic means or to request Participant’s consent to participate in the Plan by electronic means.Participant hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company.

11.Insider Trading/Market Abuse Laws.

Participant may be subject to insider trading restrictions and/or market abuse laws in applicable jurisdictions including, but not limited to, the United States and Participant’s country of residence, which may affect Participant’s ability to accept, acquire, sell or otherwise dispose of Shares or rights to Shares (e.g., RSUs) or rights linked to the value of Shares under the Plan during such times as Participant is considered to have “inside information” regarding the Company (as defined by the laws in Participant’s country).Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under the Company’s insider trading policy.

12.Country-Specific Terms and Conditions.

In no event shall the Committee or Board (or any member thereof), or the Company (or its employees, officers, directors or Affiliates) have any liability to Participant or to any other party if the RSUs or payment of the RSUs that is intended to be exempt from or compliant with Section 409A of the Code is not so exempt or compliant or for any action taken by the Committee with respect thereto.

APPENDIX

TO

ALLEGION PLC

INCENTIVE STOCK PLAN OF 2013

GLOBAL RESTRICTED STOCK UNIT AWARD AGREEMENT

COUNTRY-SPECIFIC TERMS AND CONDITIONS

This Appendix includes special terms and conditions applicable to Participant if Participant is in one of the countries listed below. These terms and conditions supplement or replace (as indicated) the terms and conditions set forth in the Award Agreement. If Participant is a citizen or resident of a country other than the one in which he or she is currently working, or if Participant transfers employment or residency to another country after the RSUs are granted, the Company, in its discretion, will determine the extent to which the terms and conditions set forth in this Appendix will apply to the Participant.

This Appendix also includes information relating to exchange control, foreign asset / account reporting requirements and other issues of which Participant should be aware with respect to his or her participation in the Plan. The information is based on the exchange control, securities and other laws in effect in the respective countries as of January 2021. Such laws are often complex and change frequently. As a result, Participant should not rely on the information herein as the only source of information relating to the consequences of participation in the Plan because the information may be out of date at the time the RSUs vest or the Shares acquired under the Plan are sold.

In addition, the information is general in nature and may not apply to Participant’s particular situation. The Company is not in a position to assure Participant of any particular result. Accordingly, Participant should seek appropriate professional advice as to how the relevant laws in his or her country may apply to his or her situation. Finally, if Participant is a citizen or resident of a country other than the one in which he or she is currently working, or if Participant transfers employment or residency to another country after the RSUs are granted, the information contained herein may not be applicable to Participant.

AUSTRALIA

Offer Document.

The Company is pleased to provide Participant with this offer to participate in the Plan. This offer sets out information regarding the grant of RSUs to Australian-resident employees and directors of the Company and its Affiliates. This offer is provided by the Company to ensure compliance of the Plan with the Australian Securities and Investments Commission’s (“ASIC”) Class Order 14/1000 and relevant provisions of the Corporations Act 2001.

In addition to the information set out in the Award Agreement, Participant is also being provided with copies of the following documents:

1)the Plan;

2)the prospectus for the Plan; and

3)an Employee Information Supplement for Australia

(collectively, the “Additional Documents”).

The Additional Documents provide further information to help Participant make an informed investment decision about participating in the Plan. Neither the Plan nor the prospectus for the Plan is a prospectus for the purposes of the Corporations Act 2001, and they have not been modified for Australia.

Participant should not rely upon any oral statements made in relation to this offer. Participant should rely only upon the statements contained in the Award Agreement and the Additional Documents when considering participation in the Plan.

Securities Law Information.

Investment in Shares involves a degree of risk. Participants who elect to participate in the Plan should monitor their participation and consider all risk factors relevant to the acquisition of Shares under the Plan as set out in the Award Agreement and the Additional Documents.

The information contained in this offer is general information only. It is not advice or information that takes into account Participant’s objectives, financial situation and needs.

Participants should consider obtaining their own financial product advice from an independent person who is licensed by ASIC to give such advice.

Additional Risk Factors for Australian Residents.

Participants should have regard to risk factors relevant to investment in securities generally and, in particular, to the holding of Shares. For example, the price at which the Company’s ordinary shares are quoted on the New York Stock Exchange may increase or decrease due to a number of factors. There is no guarantee that the price of the ordinary shares will increase. Factors which may affect the price of ordinary shares include fluctuations in the domestic and international market for listed stocks, general economic conditions, including interest rates, inflation rates, commodity and oil prices, changes to government fiscal, monetary or regulatory policies, legislation or regulation, the nature of the markets in which the Company operates and general operational and business risks.

In addition, Participants should be aware that the Australian dollar value of any Shares acquired under the Plan will be affected by the U.S. dollar/Australian dollar exchange rate. Participation in the Plan involves certain risks related to fluctuations in this rate of exchange.

Ordinary Shares.

Ordinary shares of an Irish public limited company are analogous to ordinary shares of an Australian corporation. Each holder of the ordinary shares is entitled to one vote for every share held.

Under Irish law, dividends and distributions may only be made from “distributable reserves.” Distributable reserves, broadly, means the accumulated realized profits of the Company less accumulated realized losses. In addition, no distribution or dividend may be made unless the Company’s net assets are equal to, or in excess of, the aggregate of its share capital which has been paid up or which is payable in the future plus undistributable reserves and the distribution does not reduce the Company’s net assets below such aggregate. Undistributable reserves include the share premium account, the capital redemption reserve fund, the Company’s net unrealized profits and any other reserve which the company is prohibited from distributing.

The determination as to whether or not the Company has sufficient distributable reserves to fund a dividend must be made by reference to the “relevant accounts” of the Company. The “relevant accounts” will be either the last set of the Company’s unconsolidated annual audited financial statements or unaudited financial statements prepared in accordance with the Irish Companies Acts and Generally Accepted Accounting Principles in Ireland, which give a “true and fair view” of the Company’s unconsolidated financial position. The relevant accounts must be filed in the Companies Registration Office (the official public registry for companies in Ireland).

The mechanism as to who declares a dividend and when a dividend becomes payable is governed by the Company’s articles of association. The articles of association authorize the directors to declare dividends as appear justified from the profits without the approval of the shareholders at a general meeting. The Company’s board of directors may also recommend a dividend to be approved and declared by the shareholders at a general meeting. Although the shareholders may direct that the payment be made by distribution of assets, shares or cash, no dividend issued may exceed the amount recommended by the directors. The dividends declared by directors or shareholders may be paid in the form of assets, shares or cash.

The Company’s ordinary shares are traded on the New York Stock Exchange in the United States of America under the symbol “ALLE”.

Ascertaining the Market Price of Shares.

Participants may ascertain the current market price of the Shares as traded on the New York Stock Exchange at http://www.nyse.com under the symbol “ALLE.” The Australian dollar equivalent of that price can be obtained at: http://www.rba.gov.au/statistics/frequency/exchange-rates.html.

This will not be a prediction of what the market price per Share will be when the RSUs vest or settle or of the applicable exchange rate on the actual Vesting Date or settlement date.

Tax Information.

The Plan is a plan to which Subdivision 83A-C of the Income Tax Assessment Act 1997 (Cth) applies (subject to the conditions in that Act).

For a description of the likely tax consequences of the RSUs, please refer to the Employee Information Supplement for RSUs in Australia, a link to which is available below:

[EMBED LINK TO EMPLOYEE INFORMATION SUPPLEMENT FOR RSUs IN AUSTRALIA]

AUSTRIA

Termination Due to Retirement. This provision replaces Section 3(c) of the Award Agreement:

Notwithstanding the provisions of Section 3(a) and (b) above, and unless Participant’s employment terminates for Cause, if Participant’s employment terminates due to retirement under the retirement provisions of local law in Participant’s country (“Retirement”), the Shares subject to the RSUs shall continue to vest according to the schedule set forth in Section 1, notwithstanding such termination of employment.

Exchange Control Information. If Participant holds Shares obtained through the Plan outside Austria, Participant may be subject to reporting requirements to the Austrian National Bank. An exemption applies if the value of the Shares (i) does not meet or exceed €30,000,000 as of any given quarter or (ii) does not meet or exceed €5,000,000 as of December 31 of any given year. If the former threshold is exceeded, quarterly reporting obligations are imposed, whereas if the latter threshold is exceeded, annual reporting requirements apply. Further, a separate reporting requirement may apply if any cash (e.g., proceeds from the sale of Shares) is held outside Austria. If the transaction volume of all Participant’s cash accounts abroad meets or exceeds €10,000,000, the movements and balances of all accounts must be reported monthly with the form “Meldungen SI-Forderungen und/oder SIVerpflichtungen.” Participant should consult his or her personal legal advisor to ensure compliance with applicable reporting obligations.

BELGIUM

Termination Due to Retirement. This provision replaces Section 3(c) of the Award Agreement:

Foreign Asset/Account Reporting Information. Participant is required to report any securities and bank or brokerage accounts held outside of Belgium on Participant’s annual tax return. In a separate report, Belgian residents are required to provide the National Bank of Belgium with the account details of any such foreign accounts (including the account number, bank name and country in which any such account was opened). This report, as well as additional information on how to complete it, can be found on the website of the National Bank of Belgium, www.nbb.be, under the Kredietcentrales / Centrales des crédits caption.

CANADA

Settlement. This provision supplements Section 4 of the Award Agreement:

The grant of the RSUs does not provide any right for Participant to receive a cash payment and the RSUs will be settled in Shares only.

Termination of Employment. This provision replaces Section 7(k) of the Award Agreement:

For purposes of the RSUs, Participant's employment or other service relationship will be considered terminated, and Participant's right (if any) to earn, seek damages in lieu of, vest in or otherwise benefit from any portion of the RSUs pursuant to this Award Agreement will be measured by, the date that is the earliest of:

i.the date Participant's employment with the Employer is terminated for any reason; and

ii.the date Participant receives written notice of termination from the Employer;

regardless of any period during which notice, pay in lieu of notice or related payments or damages are provided or required to be provided under local law. For greater certainty, Participant will not earn or be entitled to any pro-rated vesting for that portion of time before the date on which Participant's right to vest terminates, nor will Participant be entitled to any compensation for lost vesting.

Notwithstanding the foregoing, if applicable employment standards legislation explicitly requires continued vesting during a statutory notice period, Participant's right to vest in the RSUs, if any, will terminate effective upon the expiry of the minimum statutory notice period, but Participant will not earn or be entitled to pro-rated vesting if the Vesting Date falls after the end of the statutory notice period, nor will Participant be entitled to any compensation for lost vesting. In any event, if employment standards legislation explicitly requires continued vesting during a statutory notice period, then the additional vesting provided under Section 3(a) is deemed to be inclusive of any entitlements that arise during the applicable statutory notice period.

Securities Law Information. Participant is permitted to sell Shares acquired under the Plan through UBS or such other broker designated under the Plan, provided that the resale of such Shares takes place outside of Canada through the facilities of a stock exchange on which the Shares are listed. The Company’s ordinary shares are currently traded on the New York Stock Exchange which is located outside of Canada, under the ticker symbol “ALLE” and Shares acquired under the Plan may be sold through this exchange.

Foreign Asset/Account Reporting Information. Participant is required to report his or her foreign specified property, including Shares and rights to receive Shares (e.g., RSUs), on form T1135 (Foreign Income Verification Statement) if the total cost of the foreign specified property exceeds C$100,000 at any time during the year. RSUs must be reported (generally, at a nil cost) if the C$100,000 cost threshold is exceeded because of other foreign specified property held by Participant. When Shares are acquired, their cost generally is the adjusted cost base (“ACB”) of the Shares. The ACB would ordinarily equal the fair market value of the Shares at the time of acquisition, but if other Shares are also owned, this ACB may have to be averaged with the ACB of the other Shares. Participant should consult his or her personal tax advisor to ensure compliance with applicable reporting obligations.

The following provisions will apply to Participant if he or she is a resident of Quebec:

Language Consent. The parties acknowledge that it is their express wish that the Award Agreement, including this Appendix, as well as all documents, notices, and legal proceedings entered into, given or instituted pursuant hereto or relating directly or indirectly hereto, be drawn up in English.

Participant further authorizes the Company and its Affiliates to record such information and to keep such information in Participant’s employee file.

CHINA

Termination Due to Retirement. This provision replaces Section 3(c) of the Award Agreement:

Notwithstanding the provisions of Section 3(a) and (b) above, and unless Participant’s employment is terminated for Cause, if Participant’s employment terminates after attainment of age 55 with at least 5 years of service (“Retirement”), the Shares subject to the RSUs that have not yet vested shall vest as of the date of such termination of employment (such date also being a “Vesting Date”).

Settlement. This provision supplements Section 4 of the Award Agreement:

To facilitate compliance with any applicable laws or regulations in China, Participant agrees and acknowledges that the Company (or a brokerage firm instructed by the Company, if applicable) is entitled to (i) immediately sell all Shares issued to Participant at settlement (on Participant’s behalf and at Participant’s direction pursuant to this authorization), either at the time of settlement or when Participant ceases employment with the Employer, the Company or an Affiliate or at such other time the Company determines is necessary or desirable, or (ii) require that any Shares acquired under the Plan be held with a Company-designated broker until such Shares are sold.

Without limitation to the foregoing, if Participant’s employment terminates and Participant holds or acquires any Shares at that time, Participant (or, in circumstances where Participant’s employment terminates due to death, Participant’s estate or the person(s) who acquired the right to the Shares under applicable law) will be required to sell all Shares prior to the last trading day of the fifth month following termination of employment. If the Shares have not been sold by such date, the Company-designated broker will automatically sell all Shares on Participant’s behalf on or as soon as practicable after the last trading day of the fifth month following termination of employment and in no event later than six months following termination of employment.

Participant also agrees to sign any agreements, forms and/or consents that may be reasonably requested by the Company (or the Company’s designated brokerage firm) to effectuate the sale of the Shares and acknowledges that neither the Company nor the designated brokerage firm is under any obligation to arrange for such sale of the Shares at any particular price (it being understood that the sale will occur at the then-current market price) and that broker’s fees or commissions may be incurred in any such sale. In any event, when the Shares acquired under the Plan are sold, the proceeds of the sale of the Shares, less any Tax-Related Items and broker’s fees or commissions, will be remitted to Participant in accordance with applicable exchange control laws and regulations.

Exchange Control Restrictions. Participant understands and agrees that, if he or she is a national of the People’s Republic of China (the “PRC”) and subject to exchange control restrictions in China, he or she

will be required to immediately repatriate the proceeds of the sale of Shares and any cash dividends or Dividend Equivalents to China. Participant further understands that the repatriation of such funds may need to be effected through a special exchange control account established by the Company or an Affiliate and he or she hereby consents and agrees that such funds may be transferred to such special account prior to being delivered to Participant’s personal account.

Participant also understands that the Company will deliver any sale proceeds, cash dividends or Dividend Equivalents to Participant as soon as practicable, but that there may be delays in distributing the funds due to exchange control requirements in China. Proceeds may be paid to Participant in U.S. dollars or local currency at the Company’s discretion. If the proceeds are paid in U.S. dollars, Participant will be required to set up a U.S. dollar bank account in China so that the proceeds may be deposited into this account. If the proceeds are paid in local currency, the Company is under no obligation to secure any particular currency conversion rate and the Company may face delays in converting the proceeds to local currency due to exchange control restrictions, and Participant agrees to bear any currency fluctuation risk between the time the Shares are sold and the time (i) the Tax-Related Items are converted to local currency and remitted to the tax authorities and/or (ii) the net proceeds are converted to local currency and distributed to Participant.

Participant further agrees to comply with any other requirements that may be imposed by the Company in the future in order to facilitate compliance with exchange control requirements in China.

Exchange Control Information. PRC residents are required to report to the State Administration of Foreign Exchange (“SAFE”) details of their foreign financial assets and liabilities, as well as details of any economic transactions conducted with non-PRC residents, either directly or through financial institutions.

5.Responsibility for Taxes.

Participant acknowledges that, regardless of any action taken by the Company or, if different, Participant’s employer (the “Employer”), the ultimate liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to Participant’s participation in the Plan and legally applicable to Participant (“Tax-Related Items”) is and remains Participant’s responsibility and may exceed the amount (if any) actually withheld by the Company or the Employer.

Participant further acknowledges that the Company and the Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Option; and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Option to reduce or eliminate Participant’s liability for Tax-Related Items or achieve any particular tax result. Further, if Participant is subject to Tax‑Related Items in more than one jurisdiction, Participant acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Prior to any relevant taxable or tax withholding event, as applicable, Participant will make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, Participant authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy their obligations (if any) with regard to all Tax-Related Items by one or a combination of the following:

(a)withholding from Participant’s wages or other cash compensation payable to Participant by the Company and/or the Employer;

(b)withholding from proceeds of the sale of Shares acquired upon exercise of the Option either through a voluntary sale or through a mandatory sale arranged by the Company (on Participant’s behalf pursuant to this authorization without further consent);

(d)withholding in Shares to be issued upon exercise of the Option; and/or

(e)any other method of withholding determined by the Company to be permitted under the Plan and, to the extent required by applicable law or the Plan, approved by the Committee;

provided, however, that if Participant is a Section 16 officer of the Company under the Act, then the Committee (as constituted to satisfy Rule 16b-3 of the Act) will determine the method of withholding from alternatives (a) - (e) above and, if the Committee does not exercise its discretion prior to the applicable withholding event, then Participant will be entitled to elect the method of withholding from alternatives (a) - (e) above.

The Company may withhold for Tax-Related Items by considering minimum statutory withholding rates or other withholding rates, including maximum withholding rates applicable, in Participant's jurisdiction(s). In the event of over-withholding, Participant may receive a refund of any over-withheld amount in cash (with no entitlement to the equivalent amount in Shares) from the Company or the Employer; otherwise, Participant may be able to seek a refund from the local tax authority. In the event of under-withholding, Participant may be required to pay any additional Tax-Related Items directly to the applicable tax authority. If the obligation for Tax-Related Items is satisfied by withholding Shares, for tax purposes, Participant is deemed to have been issued the full number of Shares subject to the exercised Option, notwithstanding that a number of the Shares are held back solely for the purpose of paying the Tax-Related Items. The Companymay refuse to honor the exercise of the Option or refuse to issue or deliver the Shares or the proceeds of the sale of Shares, if Participant fails to comply with his or her obligations in connection with the Tax-Related Items.

(a)the Plan is established voluntarily by the Company, it is discretionary in nature and it may be amended, altered or discontinued by the Company at any time, to the extent permitted by the Plan;

(b)the grant of the Option is voluntary and occasional and does not create any contractual or other right to receive future grants of options, or benefits in lieu of options, even if options have been granted in the past;

(c)all decisions with respect to future option grants, if any, will be at the sole discretion of the Company;

(d)Participant is voluntarily participating in the Plan;

(e)the Option and the Shares subject to the Option, and the income and value of same, are not intended to replace any pension rights or compensation;

(f)the Option and the Shares subject to the Option, and the income and value of same, are not part of normal or expected compensation or salary for any purpose, including, but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end of service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments;

(g)unless otherwise agreed with the Company, the Option and the Shares subject to the Option, and the income and value of same, are not granted as consideration for, or in connection with, services Participant may provide as a director of an Affiliate;

(h)the grant of the Option and Participant’s participation in the Plan will not create a right to employment or be interpreted as forming or amending an employment or service contract with the Company, the Employer or any Affiliate and will not interfere with the ability of the Company, the Employer or any Affiliate, as applicable, to terminate Participant’s employment or service relationship (if any);

(i)the future value of the underlying Shares is unknown, indeterminable and cannot be predicted with certainty; if the Shares subject to the Option do not increase in value, the Option will have no value; if Participant exercises the Option and acquires Shares, the value of such Shares may increase or decrease, even below the exercise price;

(j)no claim or entitlement to compensation or damages shall arise from forfeiture of the Option resulting from Participant ceasing to provide employment or other services to the Company or the Employer (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Participant is employed or the terms of Participant’s employment agreement, if any) or from cancellation of the Option or recoupment of any financial gain resulting from exercise of the Option as described in Section 13 below;

(k)for purposes of the Option, Participant’s employment or other service relationship will be considered terminated as of the date Participant is no longer actively providing services to the Company or one of its Affiliates (regardless of the reason for such termination and whether or not later found to be

invalid or in breach of employment laws in the jurisdiction where Participant is employed or the terms of Participant’s employment agreement, if any) and, unless otherwise expressly provided in this Award Agreement or determined by the Company, Participant’s right to vest in the Option under the Plan, if any, will terminate as of such date, or will be measured with reference to such date in the case of a Group Termination Event, and will not be extended by any notice period (e.g., Participant’s period of active service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where Participant is employed or the terms of Participant’s employment agreement, if any); furthermore, in the event of termination of Participant’s employment or other service relationship (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Participant is employed or the terms of Participant’s employment agreement, if any), Participant’s right to exercise the Option after termination of employment, if any, will be measured with reference to such date and will not be extended by any notice period; the Committee shall have the exclusive discretion to determine when Participant is no longer actively providing services for purposes of the Option (including whether Participant may still be considered to be providing services while on a leave of absence);

(l)unless otherwise provided in the Plan or by the Company, in its discretion, the Option and the benefits evidenced by this Award Agreement do not create any entitlement to have the Option or any such benefits transferred to, or assumed by, another company nor to be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting the Shares; and

(m)neither the Company, nor the Employer nor any Affiliate will be liable for any foreign exchange rate fluctuation between Participant’s local currency and the United States Dollar that may affect the value of the Option or of any amounts due to Participant pursuant to the exercise of the Option or the subsequent sale of any Shares acquired upon exercise.

The Company transfers Data to UBS, Broadridge Output Solutions, Inc., Cognizant Worldwide Limited, DG3, HCL Technologies Limited, Iron Mountain, and Solium Capital, which assist the Company with the implementation, administration and management of the Plan.

(c)International Data Transfers. The Company and its service providers are based in the United States. Participant’s country or jurisdiction may have different data privacy laws and protections than the United States.

For Participants in the EEA+, the legal basis for the transfer of Data is that it is necessary for the performance of the Company's contractual obligation to deliver Shares (if the conditions of the Plan and the Award Agreement are satisfied) and, generally, to manage and administer Participant's participation in the Plan.

For Participants outside the EEA+, the legal basis for the transfer of Data is Participant’s consent.

(d)Data Retention. The Company will hold and use Data only as long as is necessary to implement, administer and manage Participant’s participation in the Plan, or as required to comply with legal or regulatory obligations, including under tax, exchange control, labor and securities laws.

Participation in the Plan is voluntary and Participant is providing the consents described herein on a purely voluntary basis. If Participant does not consent, or if Participant later seeks to revoke his or her consent, Participant’s salary from or employment and career with the Employer will not be affected; the only consequence of refusing or withdrawing consent is that the Company would not be able to grant Options under the Plan to Participant or administer or maintain Participant’s participation in the Plan.

CANADA

Form of Payment for Options. Due to legal restrictions in Canada, Participant may not pay the exercise price or Tax-Related Items by surrendering Shares that he or she already owns or by attesting to the ownership of Shares.

Termination of Employment. This provision replaces Section 6(k) of the Award Agreement:

For purposes of the Option, Participant's employment or other service relationship will be considered terminated, and Participant's right (if any) to earn, seek damages in lieu of, vest in, exercise, or otherwise benefit from any portion of the Option pursuant to this Award Agreement will be measured by, the date that is the earliest of:

i.the date Participant's employment with the Employer is terminated for any reason; and

ii.the date Participant receives written notice of termination from the Employer;

regardless of any period during which notice, pay in lieu of notice or related payments or damages are provided or required to be provided under local law. For greater certainty, Participant will not earn or be entitled to any pro-rated vesting or extended exercisability for that portion of time before the date on which Participant's right to vest in or exercise the Option terminates, nor will Participant be entitled to any compensation for lost vesting or exercisability.

Notwithstanding the foregoing, if applicable employment standards legislation explicitly requires continued vesting or exercisability during a statutory notice period, Participant's right to vest in or exercise the Option, if any, will terminate effective upon the expiry of the minimum statutory notice period, but Participant will not earn or be entitled to pro-rated vesting or extended exercisability if the Vesting Date or exercisability period falls after the end of the statutory notice period, nor will Participant be entitled to any compensation for lost vesting or exercisability. In any event, if employment standards legislation explicitly requires continued vesting or exercisability during a statutory notice period, then the additional vesting and exercisability provided under Section 3 is deemed to be inclusive of any entitlements that arise during the applicable statutory notice period.

Securities Law Information. Participant is permitted to sell Shares acquired under the Plan through UBS or such other broker designated under the Plan, provided that the resale of such Shares takes place outside of Canada through the facilities of a stock exchange on which the Shares are listed. The Company’s ordinary shares are currently traded on the New York Stock Exchange which is located outside of Canada, under the ticker symbol “ALLE” and Shares acquired under the Plan may be sold through this exchange.

Foreign Asset/Account Reporting Information. Participant is required to report his or her foreign specified property, including Shares and rights to receive Shares (e.g., Options), on form T1135 (Foreign Income Verification Statement) if the total cost of the foreign specified property exceeds C$100,000 at any time during the year. Options must be reported (generally at a nil cost) if the C$100,000 cost threshold is exceeded because of other foreign specified property held by Participant. When Shares are acquired, their cost generally is the adjusted cost base (“ACB”) of the Shares. The ACB would ordinarily equal the fair market value of the Shares at the time of acquisition, but if other Shares are also owned, this ACB may have to be averaged with the ACB of the other Shares. Participant should consult his or her personal tax advisor to ensure compliance with applicable reporting obligations.

The following provisions will apply to Participant if he or she is a resident of Quebec:

Language Consent. The parties acknowledge that it is their express wish that the Award Agreement, including this Appendix, as well as all documents, notices, and legal proceedings entered into, given or instituted pursuant hereto or relating directly or indirectly hereto, be drawn up in English.

China so that the proceeds may be deposited into this account.

On a date as soon as practicable following the end of the Performance Period, the Committee shall certify the extent to which the performance vesting conditions set forth in Appendix A have been met (the “Certification Date”).

Shares issued pursuant to this Section 6 shall be fully paid and non-assessable. Participant will not have any of the rights or privileges of a shareholder of the Company in respect of any Shares subject to the PSUs unless and until such Shares have been issued to Participant.

7.Change in Control.

In the event of a Change in Control, the treatment of the PSUs will be governed by the terms of the Plan.

8.Responsibility for Taxes.

Participant acknowledges that, regardless of any action taken by the Company or, if different, Participant’s employer (the “Employer”), the ultimate liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to Participant’s participation in the Plan and legally applicable to Participant (“Tax-Related Items”) is and remains Participant’s responsibility and may exceed the amount (if any) actually withheld by the Company or the Employer. Participant further acknowledges that the Company and the Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the PSUs; and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the PSUs to reduce or eliminate Participant’s liability for Tax-Related Items or achieve any particular tax result. Further, if Participant is subject to Tax-Related Items in more than one jurisdiction, Participant acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

To satisfy any withholding obligations of the Company and/or the Employer with respect to Tax-Related Items (other than U.S. Federal Insurance Contribution Act taxes or other Tax-Related Items which become payable in a year prior to the year in which the Shares are issued pursuant to the RSUs, and other than Tax-Related Items due on Dividend Equivalents), the Company will withhold Shares otherwise issuable upon settlement of the PSUs. Alternatively, or in addition, in connection with any applicable taxable or tax withholding event, Participant authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy their obligations (if any) with regard to all Tax-Related Items by one or a combination of the following:

(a)withholding from Participant’s wages or other cash compensation payable to Participant by the Company or the Employer;

(b)withholding from proceeds of the sale of Shares acquired upon settlement of the PSUs either through a voluntary sale or through a mandatory sale arranged by the Company(on Participant’s behalf pursuant to this authorization without further consent);

(c)requiring Participant to tender a cash payment to the Company or an Affiliate in the amount of the Tax-Related Items; and/or

(d)any other method of withholding determined by the Company to be permitted under the Plan and, to the extent required by applicable law or under the Plan, approved by the Committee;

provided, however, that if Participant is a Section 16 officer of the Company under the Act, the withholding methods described in this Section 8(a) through (d) will only be used if the Committee (as constituted to satisfy Rule 16b-3 of the Act) determines, in advance of the applicable withholding event, that one such withholding method will be used in lieu of withholding Shares.

The Company may withhold for Tax-Related Items by considering minimum statutory withholding rates or other withholding rates, including maximum withholding rates applicable, in Participant's jurisdiction(s). In the event of over-withholding, Participant may receive a refund of any over-withheld amount in cash (with no entitlement to the equivalent amount in Shares) from the Company or the Employer; otherwise, Participant may be able to seek a refund from the local tax authority. In the event of under-withholding, Participant may be required to pay any additional Tax-Related Items directly to the applicable tax authority. If the obligation for Tax-Related Items is satisfied by withholding Shares, for tax purposes, Participant is deemed to have been issued the full number of Shares subject to the vested portion of the PSUs, notwithstanding that a number of the Shares are held back solely for the purpose of paying the Tax-Related Items. The Companymay refuse to issue or deliver the Shares or the proceeds of the sale of Shares, if Participant fails to comply with his or her obligations in connection with the Tax-Related Items.

9.Nature of Grant.

In accepting the PSUs, Participant acknowledges, understands and agrees that:

(a)the Plan is established voluntarily by the Company, it is discretionary in nature and it may be amended, altered or discontinued by the Company at any time, to the extent permitted by the Plan;

(b)the grant of the PSUs is voluntary and occasional and does not create any contractual or other right to receive future grants of performance stock units, or benefits in lieu of performance stock units, even if performance stock units have been granted in the past;

(c)all decisions with respect to future performance stock unit grants, if any, will be at the sole discretion of the Company;

(e)the PSUs and the Shares subject to the PSUs, and the income and value of same, are not intended to replace any pension rights or compensation;

(g)unless otherwise agreed with the Company, the PSUs and the Shares subject to the PSUs, and the income and value of same, are not granted as consideration for, or in connection with, services Participant may provide as a director of an Affiliate;

(h)the PSU grant and Participant’s participation in the Plan will not create a right to employment or be interpreted as forming or amending an employment or service contract with the Company,

the Employer or any Affiliate and will not interfere with the ability of the Company, the Employer or any Affiliate, as applicable, to terminate Participant's employment or service relationship (if any);

(i)the future value of the underlying Shares is unknown, indeterminable and cannot be predicted with certainty;

(j)no claim or entitlement to compensation or damages shall arise from forfeiture of the PSUs resulting from Participant ceasing to provide employment or other services to the Company or the Employer (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Participant is employed or the terms of Participant's employment agreement, if any) or from cancellation of the PSUs or recoupment of any financial gain resulting from the PSUs as described in Section 16 below;

(l)unless otherwise provided in the Plan or by the Company, in its discretion, the PSUs and the benefits evidenced by this Award Agreement do not create any entitlement to have the PSUs or any such benefits transferred to, or assumed by another company nor to be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting the Shares; and

(m)neither the Company, nor the Employer nor any Affiliate will be liable for any foreign exchange rate fluctuation between Participant’s local currency and the United States Dollar that may affect the value of the PSUs or of any amounts due to Participant pursuant to the settlement of the PSUs or the subsequent sale of any Shares acquired upon settlement.

10.No Advice Regarding Grant.

The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding Participant’s participation in the Plan or his or her acquisition or sale of the underlying Shares.

The Company, with its registered address at Block D, Iveagh Court, Harcourt Road, Dublin 2, Ireland, acts as the data controller in respect of such Data.

For Participants in the European Union / European Economic Area / Switzerland / United Kingdom ("EEA+"), the legal basis for the processing of Data is that it is necessary for the performance of the Company's contractual obligation to deliver Shares (if the conditions of the Plan and the Award Agreement are satisfied) and, generally, to manage and administer Participant's participation in the Plan.

For Participants outside the EEA+, the legal basis for the processing of Data is Participant’s consent.

(b)Stock Plan Administration Service Providers. The Company transfers Data to UBS, Broadridge Output Solutions, Inc., Cognizant Worldwide Limited, DG3, HCL Technologies Limited, Iron Mountain, and Solium Capital, which assist the Company with the implementation, administration and management of the Plan. In the future, the Company may select different service providers and share Data with such other providers serving in a similar manner. Participant may be asked to acknowledge or (where applicable) agree to separate terms and data processing practices with the service providers, with such agreement (where applicable) being a condition to the ability to participate in the Plan.

(c)International Data Transfers. The Company and its service providers are based in the United States. Participant’s country or jurisdiction may have different data privacy laws and protections than the United States.

For Participants in the EEA+, the legal basis for the transfer of Data is that it is necessary for the performance of the Company's contractual obligation to deliver Shares (if the conditions of the Plan and the Award Agreement are satisfied) and, generally, to manage and administer Participant's participation in the Plan.

For Participants outside of the EEA+, the legal basis for the transfer of Data is Participant’s consent.

(d)Data Retention. The Company will hold and use Data only as long as is necessary to implement, administer and manage Participant’s participation in the Plan, or as required to comply with legal or regulatory obligations, including under tax, exchange control, labor and securities laws.

(f)Declaration of Consent (for Participants outside the EEA+ Only). By accepting this award of PSUs and indicating consent via the Company’s online acceptance procedure, Participant is declaring that he or she agrees with the data processing practices described herein and consents to the

collection, processing and use of Data by the Company and the transfer of Data to the recipients mentioned herein, including recipients located in countries which may not have a similar level of protection from the perspective of the data protection laws in Participant’s country.

Participation in the Plan is voluntary and Participant is providing the consents described herein on a purely voluntary basis. If Participant does not consent, or if Participant later seeks to revoke his or her consent, Participant’s salary from or employment and career with the Employer will not be affected; the only consequence of refusing or withdrawing consent is that the Company would not be able to grant PSUs under the Plan to Participant or administer or maintain Participant’s participation in the Plan.

Accordingly, all provisions included in this Award Agreement, or incorporated by reference, will be interpreted and administered in accordance with that intent. If any provision of the Plan or this Award Agreement would otherwise conflict with or frustrate this intent, that provision will be interpreted and deemed amended or limited so as to avoid the conflict. However, the Company makes no representation that the PSUs are exempt from or compliant with Section 409A of the Code and makes no undertaking to preclude Section 409A from applying to the PSUs. In no event shall the Committee or Board (or any member thereof), or the Company (or its employees, officers, directors or Affiliates) have any liability to Participant or to any other party if the PSUs or payment of the PSUs that is intended to be exempt from or compliant with Section 409A of the Code is not so exempt or compliant or for any action taken by the Committee with respect thereto.

19.Severability.

The provisions of this Award Agreement are severable and if any one or more provisions are determined to be illegal or otherwise unenforceable, in whole or in part, the remaining provisions shall nevertheless be binding and enforceable.

20.Language.

Participant acknowledges and represents that he or she is proficient in the English language or has consulted with an advisor who is sufficiently proficient in English, as to allow Participant to understand the terms of this Award Agreement and any other documents related to the Plan. If Participant has received this Award Agreement or any other document related to the Plan translated into a language other than English and if the meaning of the translated version is different than the English version, the English version will control.

21.Waiver.

Participant acknowledges that a waiver by the Company of breach of any provision of this Award Agreement shall not operate or be construed as a waiver of any other provision of this Award Agreement, or of any subsequent breach by Participant or any other participant in the Plan.

22.Acknowledgement of Availability of Plan Prospectus.

Participant acknowledges that he or she has been provided with access to a copy of the Plan prospectus and Plan document, links to both of which are available below:

BASED ON EARNINGS PER SHARE ("EPS") GROWTH VERSUS PRE-ESTABLISHED THRESHOLD, TARGET, AND MAXIMUM GOALS

The number of Shares subject to the PSUs that are eligible to vest based upon the attainment level of the EPS performance goal during the Performance Period shall be equal to the product of (a) 50%, multiplied by (b) the number of Shares subject to the PSUs at the target performance level set forth in Section 1 of the Agreement, multiplied by (c) the applicable Payout Level set forth below.

Performance Level	EPS Performance	Payout Level
Below Threshold	< $ X.XX / share	0% (no payout)

50% OF PSU ACHIEVEMENT

BASED ON TOTAL SHAREHOLDER RETURN ("TSE") VERSUS S&P 400 CAPITAL GOODS INDEX

The number of Shares subject to the PSUs that are eligible to vest based upon the attainment level of the TSR performance goal during the Performance Period shall be equal to the product of (a) 50%, multiplied by (b) the number of Shares subject to the PSUs at the target performance level set forth in Section 1 of the Agreement, multiplied by (c) the applicable Payout Level set forth below.

Performance Level	Relative Performance Against the Standard & Poors 400 Capital Goods Index	Payout Level
Below Threshold	< 25th percentile	0% (no payout)
Threshold	25th percentile	50%
Target	50th percentile	100%
Maximum	≥ 75th percentile	200%

▪For purposes of measuring TSR over the Performance Period, a point-to-point measurement is used. TSR is defined as the total return dollars (stock price appreciation plus dividends) at the end of the Performance Period compared to the stock price at the beginning of the Performance Period.

▪To account for stock price volatility, the average of the closing price over the 30 trading days ending on the first day of the Performance Period and the 30 trading days ending on the last day of the Performance Period will be used as the applicable stock price for purposes of the calculation of TSR.

▪TSR will be compared against TSR of the companies in the S&P 400 Capital Goods Index to determine relative performance during the Performance Period.

▪If TSR is not positive (i.e., greater than 0%), payout cannot exceed the Payout Level for Target for the TSR portion of the award.

▪Performance attainment at levels among the Threshold, Target and Maximum goals will be subject to interpolation.

APPENDIX B

TO

ALLEGION PLC

INCENTIVE STOCK PLAN OF 2013

GLOBAL PERFORMANCE STOCK UNIT AWARD AGREEMENT

FOR THE 20XX - 20XX PERFORMANCE PERIOD

COUNTRY-SPECIFIC TERMS AND CONDITIONS

This Appendix B includes special terms and conditions applicable to Participant if Participant is in one of the countries listed below. These terms and conditions supplement or replace (as indicated) the terms and conditions set forth in the Award Agreement. If Participant is a citizen or resident of a country other than the one in which he or she is currently working, or if Participant transfers employment or residency to another country after the PSUs are granted, the Company, in its discretion, will determine the extent to which the terms and conditions set forth in this Appendix B will apply to Participant.

This Appendix B also includes information relating to exchange control, foreign asset / account reporting requirements and other issues of which Participant should be aware with respect to his or her participation in the Plan. The information is based on the exchange control, securities and other laws in effect in the respective countries as of January 2021. Such laws are often complex and change frequently. As a result, Participant should not rely on the information herein as the only source of information relating to the consequences of participation in the Plan because the information may be out of date at the time the PSUs vest or the Shares acquired under the Plan are sold.

In addition, the information is general in nature and may not apply to Participant’s particular situation. The Company is not in a position to assure Participant of any particular result. Accordingly, Participant should seek appropriate professional advice as to how the relevant laws in his or her country may apply to his or her situation. Finally, if Participant is a citizen or resident of a country other than the one in which he or she is currently working, or if Participant transfers employment or residency to another country after the PSUs are granted, the information contained herein may not be applicable to Participant.

AUSTRALIA

Offer Document.

The Company is pleased to provide Participant with this offer to participate in the Plan. This offer sets out information regarding the grant of PSUs to Australian-resident employees and directors of the Company and its Affiliates. This offer is provided by the Company to ensure compliance of the Plan with the Australian Securities and Investments Commission’s (“ASIC”) Class Order 14/1000 and relevant provisions of the Corporations Act 2001.

In addition to the information set out in the Award Agreement, Participant is also being provided with copies of the following documents:

1)the Plan;

2)the prospectus for the Plan; and

3)an Employee Information Supplement for Australia

(collectively, the “Additional Documents”).

The Additional Documents provide further information to help Participant make an informed investment decision about participating in the Plan. Neither the Plan nor the prospectus for the Plan is a prospectus for the purposes of the Corporations Act 2001, and they have not been modified for Australia.

Participant should not rely upon any oral statements made in relation to this offer. Participant should rely only upon the statements contained in the Award Agreement and the Additional Documents when considering participation in the Plan.

Securities Law Information.

Investment in Shares involves a degree of risk. Participants who elect to participate in the Plan should monitor their participation and consider all risk factors relevant to the acquisition of Shares under the Plan as set out in the Award Agreement and the Additional Documents.

The information contained in this offer is general information only. It is not advice or information that takes into account Participant’s objectives, financial situation and needs.

Participants should consider obtaining their own financial product advice from an independent person who is licensed by ASIC to give such advice.

Additional Risk Factors for Australian Residents.

Participants should have regard to risk factors relevant to investment in securities generally and, in particular, to the holding of Shares. For example, the price at which the Company’s ordinary shares are quoted on the New York Stock Exchange may increase or decrease due to a number of factors. There is no guarantee that the price of the ordinary shares will increase. Factors which may affect the price of ordinary shares include fluctuations in the domestic and international market for listed stocks, general economic conditions, including interest rates, inflation rates, commodity and oil prices, changes to government fiscal, monetary or regulatory policies, legislation or regulation, the nature of the markets in which the Company

operates and general operational and business risks.

In addition, Participants should be aware that the Australian dollar value of any Shares acquired under the Plan will be affected by the U.S. dollar/Australian dollar exchange rate. Participation in the Plan involves certain risks related to fluctuations in this rate of exchange.

Ordinary Shares.

Ordinary shares of an Irish public limited company are analogous to ordinary shares of an Australian corporation. Each holder of the ordinary shares is entitled to one vote for every share held.

Under Irish law, dividends and distributions may only be made from “distributable reserves.” Distributable reserves, broadly, means the accumulated realized profits of the Company less accumulated realized losses. In addition, no distribution or dividend may be made unless the Company’s net assets are equal to, or in excess of, the aggregate of its share capital which has been paid up or which is payable in the future plus undistributable reserves and the distribution does not reduce the Company’s net assets below such aggregate. Undistributable reserves include the share premium account, the capital redemption reserve fund, the Company’s net unrealized profits and any other reserve which the company is prohibited from distributing.

The determination as to whether or not the Company has sufficient distributable reserves to fund a dividend must be made by reference to the “relevant accounts” of the Company. The “relevant accounts” will be either the last set of the Company’s unconsolidated annual audited financial statements or unaudited financial statements prepared in accordance with the Irish Companies Acts and Generally Accepted Accounting Principles in Ireland, which give a “true and fair view” of the Company’s unconsolidated financial position. The relevant accounts must be filed in the Companies Registration Office (the official public registry for companies in Ireland).

The mechanism as to who declares a dividend and when a dividend becomes payable is governed by the Company’s articles of association. The articles of association authorize the directors to declare dividends as appear justified from the profits without the approval of the shareholders at a general meeting. The Company’s board of directors may also recommend a dividend to be approved and declared by the shareholders at a general meeting. Although the shareholders may direct that the payment be made by distribution of assets, shares or cash, no dividend issued may exceed the amount recommended by the directors.The dividends declared by directors or shareholders may be paid in the form of assets, shares or cash.

The Company’s ordinary shares are traded on the New York Stock Exchange in the United States of America under the symbol “ALLE”.

Ascertaining the Market Price of Shares.

Participants may ascertain the current market price of the Shares as traded on the New York Stock Exchange at http://www.nyse.com under the symbol “ALLE.” The Australian dollar equivalent of that price can be obtained at: http://www.rba.gov.au/statistics/frequency/exchange-rates.html.

This will not be a prediction of what the market price per Share will be when the PSUs vest or settle or of the applicable exchange rate on the actual Vesting Date or settlement date.

Tax Information.

The Plan is a plan to which Subdivision 83A-C of the Income Tax Assessment Act 1997 (Cth) applies (subject to the conditions in that Act).

For a description of the likely tax consequences of the PSUs, please refer to the Employee Information Supplement for PSUs in Australia, a link to which is available below:

Group Termination; Job Elimination / Change / Relocation. This provision replaces Section 5(a) of the Award Agreement:

If Participant’s employment terminates involuntarily by reason of (i) a group termination (including, but not limited to, terminations resulting from sale of a business or division, outsourcing of an entire function, reduction in workforce or closing of a facility) (a “Group Termination Event”) or (ii) job elimination, substantial change in the nature of Participant’s position or job relocation, a pro-rated number of Shares, based on the fulfillment of the performance vesting conditions at target level of performance and the number of days during the Performance Period that Participant was actively employed by the Company or an Affiliate, shall vest. All other PSUs and associated Dividend Equivalents shall be forfeited and Participant shall have no right to or interest in such PSUs, the underlying Shares or any associated Dividend Equivalents.

Termination Due to Retirement. This provision replaces Section 5(c) of the Award Agreement:

If Participant’s employment terminates after attainment of age 55 with at least 5 years of service (“Retirement”), and unless Participant’s employment terminates for Cause, a pro-rated number of Shares, based on the fulfillment of the performance vesting conditions at target level performance and the number of days during the Performance Period that Participant was actively employed by the Company or an Affiliate, shall vest. All other PSUs and associated Dividend Equivalents shall be forfeited and Participant shall have no right to or interest in such PSUs, the underlying Shares or any associated Dividend Equivalents.

Settlement. This provision supplements Section 6 of the Award Agreement:

If Participant’s employment terminates in the circumstances set forth in Sections 5(a) or 5(c) above, then on or as soon as practicable after such termination of employment, the Company shall cause to be issued to Participant Shares with respect to any PSUs that became vested pursuant to such section.

To facilitate compliance with any applicable laws or regulations in China, Participant agrees and acknowledges that the Company (or a brokerage firm instructed by the Company, if applicable) is entitled to (i) immediately sell all Shares issued to Participant at settlement (on Participant’s behalf and at Participant’s direction pursuant to this authorization), either at the time of settlement or when Participant ceases employment with the Employer, the Company or an Affiliate or at such other time the Company determines is necessary or desirable, or (ii) require that any Shares acquired under the Plan be held with a Company-designated broker until such Shares are sold. Without limitation to the foregoing, if Participant’s employment terminates and Participant holds or acquires any Shares at that time, Participant (or, in circumstances where Participant’s employment terminates due to death, Participant’s estate or the person(s) who acquired the right to the Shares under applicable law) will be required to sell all Shares prior to the last trading day of the fifth month following termination of employment. If the Shares have not been sold by such date, the Company-designated broker will automatically sell all Shares on Participant’s behalf on or as

soon as practicable after the last trading day of the fifth month following termination of employment and in no event later than six months following termination of employment. Participant also agrees to sign any agreements, forms and/or consents that may be reasonably requested by the Company (or the Company’s designated brokerage firm) to effectuate the sale of the Shares and acknowledges that neither the Company nor the designated brokerage firm is under any obligation to arrange for such sale of the Shares at any particular price (it being understood that the sale will occur at the then-current market price) and that broker’s fees or commissions may be incurred in any such sale. In any event, when the Shares acquired under the Plan are sold, the proceeds of the sale of the Shares, less any Tax-Related Items and broker’s fees or commissions, will be remitted to Participant in accordance with applicable exchange control laws and regulations.

Exchange Control Restrictions. Participant understands and agrees that, if he or she is a national of the People’s Republic of China (the “PRC”) and subject to exchange control restrictions in China, he or she will be required to immediately repatriate the proceeds of the sale of Shares and any cash dividends or Dividend Equivalents to China. Participant further understands that the repatriation of such funds may need to be effected through a special exchange control account established by the Company or an Affiliate and he or she hereby consents and agrees that such funds may be transferred to such special account prior to being delivered to Participant’s personal account. Participant also understands that the Company will deliver any sale proceeds, cash dividends or Dividend Equivalents to Participant as soon as practicable, but that there may be delays in distributing the funds due to exchange control requirements in China. Proceeds may be paid to Participant in U.S. dollars or local currency at the Company’s discretion. If the proceeds are paid in U.S. dollars, Participant will be required to set up a U.S. dollar bank account in China so that the proceeds may be deposited into this account. If the proceeds are paid in local currency, the Company is under no obligation to secure any particular currency conversion rate and the Company may face delays in converting the proceeds to local currency due to exchange control restrictions, and Participant agrees to bear any currency fluctuation risk between the time the Shares are sold and the time (i) the Tax-Related Items are converted to local currency and remitted to the tax authorities and/or (ii) the net proceeds are converted to local currency and distributed to Participant. Participant further agrees to comply with any other requirements that may be imposed by the Company in the future in order to facilitate compliance with exchange control requirements in China.

Exchange Control Information. PRC residents are required to report to the State Administration of Foreign Exchange ("SAFE") details of their foreign financial assets and liabilities, as well as details of any economic transactions conducted with non-PRC residents, either directly or through financial institutions. Under these rules, Participant may be subject to reporting obligations for the PSUs and/or the Shares acquired under the Plan and any Plan-related transactions.

MEXICO

Labor Law Policy and Acknowledgment. Participant expressly recognizes that Allegion plc, with registered offices at Earlsfort Centre, Earlsfort Terrace, Dublin, Ireland, is solely responsible for the administration of the Plan and that Participant’s participation in the Plan and acquisition of Shares do not constitute an employment relationship between Participant and the Company since Participant is participating in the Plan on a wholly commercial basis and Participant’s sole Employer is either Allegion de Mexico, S. de R.L. de C.V. or Schlage de Mexico SA de CV (“Allegion-Mexico”). Based on the foregoing, Participant expressly recognizes that the Plan and the benefits that Participant may derive from his or her participation in the Plan do not establish any rights between Participant and Allegion-Mexico, and do not form part of the employment conditions and/or benefits provided by Allegion-Mexico and any modification of the Plan or its termination shall not constitute a change or impairment of the terms and conditions of Participant’s employment.

Participant further understands that his or her participation in the Plan is a result of a unilateral and discretionary decision of the Company; therefore, the Company reserves the absolute right to amend and/or discontinue Participant’s participation at any time without any liability to Participant.

Finally, Participant hereby declares that he or she does not reserve any action or right to bring any claim against the Company for any compensation or damages regarding any provision of the Plan or the benefits derived under the Plan, and Participant therefore grants a full and broad release to the Company, its Affiliates, branches, representation offices, its shareholders, officers, agents or legal representatives with respect to any claim that may arise.

Plan Document Acknowledgment. By accepting the PSUs, Participant acknowledges that he or she has received a copy of the Plan, has reviewed the Plan and the Award Agreement in their entirety and fully understands and accepts all provisions of the Plan and the Award Agreement. In addition, by accepting the PSUs, Participant further acknowledges that he or she has read and specifically and expressly approves the terms and conditions in Section 9 of the Award Agreement (“Nature of the Grant”), in which the following is clearly described and established: (i) participation in the Plan does not constitute an acquired right; (ii) the Plan and participation in the Plan is offered by the Company on a wholly discretionary basis; (iii) participation in the Plan is voluntary; and (iv) neither the Company, the Employer nor any Affiliate is responsible for any decrease in the value of the Shares underlying the PSUs.

Política de la Ley Laboral y Reconocimiento. El Participante reconoce expresamente que Allegion plc, con oficinas registradas ubicadas a Earlsfort Centre, Earlsfort Terrace, Dublin, Ireland, es el único responsable de la administración del Plan y que participación del Participante en el mismo y la adquisición de Acciones no constituye de ninguna manera una relación laboral entre el Participante y la Compañía, debido a que la participación de esa persona en el Plan deriva únicamente de una relación comercial y el único Patrón del participante es Allegion de Mexico, S. de R.L. de C.V. o Schlage de Mexico SA de CV(“Allegion-México”). Derivado de lo anterior, el Participante reconoce expresamente que el Plan y los beneficios que pudieran derivar para el Participante por su participación en el mismo, no establecen ningún derecho entre el Participante y Allegion-México, y no forman parte de las condiciones laborales y/o prestaciones otorgadas por Allegion-México, y cualquier modificación al Plan o la terminación del mismo de ninguna manera podrá ser interpretada como una modificación o desmejora de los términos y condiciones de trabajo del Participante.

Asimismo, el Participante reconoce que su participación en el Plan es resultado de la decisión unilateral y discrecional de la Compañía, por lo tanto, la Compañía se reserva el derecho absoluto para modificar y/o discontinuar la participación del Participante en cualquier momento, sin ninguna responsabilidad hacia el Participante.

Finalmente el Participante manifiesta que no se reserva ninguna acción o derecho que ejercitar en contra dela Compañía, por cualquier compensación o daños o perjuicios en relación con cualquier disposición del Plan o de los beneficios derivados del mismo, y en consecuencia exime amplia y completamente a la Compañía, sus Afiliadas, sucursales, oficinas de representación, sus accionistas, administradores, agentes y representantes legales con respecto a cualquier reclamo que pudiera surgir.

Reconocimiento de Documentos del Plan: Al aceptar las Unidades de Acciones por Desempeño (PSU), el Participante reconoce que ha recibido copias del Plan, que ha revisado el Plan y el Acuerdo de Concesión en su totalidad y entiende y acepta los términos del Plan y del Acuerdo de Concesión. Adicionalmente, al aceptar los PSU, el Participante reconoce que ha leído y específica y expresamente aprueba los términos y condiciones del Sección 9 del Acuerdo de Concesión (denominado "Naturaleza de la Concesión"), donde claramente se establece que (i) la participación en el Plan no constituye un derecho adquirido, (ii) el Plan y la participación en el Plan es ofrecido por la Compañía en forma totalmente discresional; (iii) la participación en el Plan es voluntaria; y (iv) ni la Compañía ni el Patrón ni su Afiliada es responsable por el decremento en el valor de las acciones de los PSU.

Securities Law Information.

In addition, the Plan, the Award Agreement and any other document relating to the PSUs may not be publicly distributed in Mexico. These materials are addressed to Participant only because of Participant’s existing relationship with the Company and these materials should not be reproduced or copied in any form.

UNITED KINGDOM (THE “U.K.”)

Termination Due to Retirement. This provision replaces Section 5(c) of the Award Agreement:

If Participant’s employment terminates due to retirement under the retirement provisions of local law in Participant’s country (“Retirement”), and unless Participant’s employment terminates for Cause, a pro-rated number of Shares, based on the fulfillment of the performance vesting conditions as measured at the end of the Performance Period and determined by the Committee in Section 6 below and the number of days during the Performance Period that Participant was actively employed by the Company or an Affiliate, shall vest. All other PSUs and associated Dividend Equivalents shall be forfeited and Participant shall have no right to or interest in such PSUs, the underlying Shares or any associated Dividend Equivalents.

Responsibility for Taxes. This provision supplements Section 6 of the Award Agreement:

Without limitation to Section 6 of the Award Agreement, Participant agrees that Participant is liable for all Tax-Related Items and hereby covenants to pay all such Tax-Related Items, as and when requested by the Company or the Employer or by Her Majesty's Revenue and Customs (“HMRC”) (or any other tax authority or any other relevant authority). Participant also agrees to indemnify and keep indemnified the Company and the Employer against any Tax-Related Items that they are required to pay or withhold or have paid or will pay to HMRC (or any other tax authority or any other relevant authority) on Participant’s behalf.

Notwithstanding the foregoing, if Participant is an executive officer or director (as within the meaning of Section 13(k) of the Act), the terms of the immediately foregoing provision will not apply. In the event that Participant is an executive officer or director and the income tax is not collected from or paid by Participant within ninety (90) days of the end of the U.K. tax year in which an event giving rise to the indemnification described above occurs, the amount of any uncollected income tax may constitute a benefit to Participant on which additional income tax and national insurance contributions may be payable. Participant acknowledges that he or she will be responsible for reporting and paying any income tax due on this additional benefit directly to the HMRC under the self-assessment regime and for paying the Company or the Employer, as applicable, the amount of any employee national insurance contributions due on this additional benefit.

ALLEGION PLC

INCENTIVE STOCK PLAN OF 2013

RESTRICTED STOCK UNIT AWARD AGREEMENT

DATED AS OF FEBRUARY 20, 2020 (“GRANT DATE”)

Allegion plc (the “Company”) hereby grants to Chris Muhlenkamp (“Participant”) a restricted stock unit award (the “RSUs”) with respect to 3,867 ordinary shares of the Company (the “Shares”), pursuant to and subject to the terms and conditions set forth in the Company’s Incentive Stock Plan of 2013 (the “Plan”) and to the terms and conditions set forth in this Restricted Stock Unit Award Agreement (the “Award Agreement”), including any appendix to the Award Agreement for Participant’s country (the “Appendix”). Unless otherwise defined herein, the terms defined in the Plan shall have the same meanings in this Award Agreement.

1.Vesting Schedule.

Participant’s right to receive Shares subject to the RSUs shall vest in accordance with the table below (each date being a “Vesting Date”), subject to Participant’s continued employment with the Company or an Affiliate through April 1, 2021, unless otherwise provided in this Award Agreement.

Vest Date	Quantity
April 01, 2021	1,933
April 01, 2022	1,934

2.Dividend Equivalents.

Participant shall be entitled to receive an amount equal to any cash dividend paid by the Company upon one Share for each RSU held by Participant when such dividend is paid (“Dividend Equivalent”), provided that, (i) Participant shall have no right to receive the Dividend Equivalents unless and until the associated RSUs vest, (ii) Dividend Equivalents shall not accrue interest and (iii) Dividend Equivalents shall be paid in cash at the time that the associated RSUs vest.

3.Termination of Employment.

(a)Group Termination

(i) If prior to April 1, 2021, Participant’s employment terminates involuntarily by reason of a group termination (including, but not limited to, terminations resulting from sale of a business or division, outsourcing of an entire function, reduction in workforce or closing of a facility) (a “Group Termination Event”), the number of Shares subject to the RSUs that would have vested within 12 months of termination of Participant’s active employment shall continue to vest according to the schedule set forth in Section 1, notwithstanding such termination of employment.

(ii) If on or after April 1, 2021, Participant’s employment terminates involuntarily by reason of a Group Termination Event, the number of Shares subject to the RSUs that would have vested within 12 months of termination of Participant’s active employment shall vest as of the date of termination of active employment (such date also being a “Vesting Date”).

Under either Section 3(a)(i) or 3(a)(ii), all other RSUs and associated Dividend Equivalents that do not vest in connection with Participant’s Group Termination Event shall be forfeited as of the date of termination of active employment, and Participant shall have no right to or interest in such RSUs, the underlying Shares or any associated Dividend Equivalents.

(b)Termination Due to Disability

(i) If prior to April 1, 2021, Participant’s employment terminates by reason of disability, the Shares subject to the RSUs shall continue to vest according to the schedule set forth in Section 1, notwithstanding such termination of employment.

(ii) If on or after April 1, 2021, Participant’s employment terminates by reason of disability, the Shares subject to the RSUs that have not yet vested shall vest as of the date of such termination of employment (such date also being a “Vesting Date”).

(c)Special Termination by Agreement

Unless Participant's employment terminates for cause as defined in Section 3(e) below, if Participant's employment terminates prior to April 1, 2021 on a date that has been mutually agreed with the Company's Chief Executive Officer, the Shares subject to the RSUs shall continue to vest according to the schedule set forth in Section 1, notwithstanding such termination of employment.

(d)Termination Due to Death

If Participant’s employment terminates due to death, the Shares subject to the RSUs that have not yet vested shall vest as of the date of such termination of employment (such date also being a “Vesting Date”).

(e)Termination Due to Any Other Reason

If Participant’s employment terminates (i) for any reason or in any circumstances other than those specified in Section 3(a) through (d) above or (ii) for cause in the circumstances specified in Section 3(c) above, all unvested RSUs and associated Dividend Equivalents shall be forfeited as of the date of termination of active employment and Participant shall have no right to or interest in such RSUs, the underlying Shares or any associated Dividend Equivalents. For purposes of this Section 3(e), “cause” shall mean (x) any action by Participant involving willful malfeasance or willful gross misconduct having a demonstrable adverse effect on the Company or an Affiliate; (y) Participant being convicted of a felony under the laws of the United States or any state or district (or the equivalent in any foreign jurisdiction); or (z) any material violation of the Company’s code of conduct, as in effect from time to time.

4.Settlement.

(a) General

On or as soon as administratively practicable (and any event within 30 days) following each Vesting Date, the Company shall cause to be issued to Participant Shares with respect to the RSUs that become vested on such Vesting Date. Notwithstanding the foregoing, if Participant is subject to U.S. federal income tax on any part of the payment of the RSUs and the RSUs are considered non-qualified deferred compensation subject to Section 409A of the Code, the RSUs shall be settled within 30 days of the earliest to occur of the following dates or events, subject to any delay required by Section 4(b) below: (i) the Vesting Dates set forth in Section 1 in the case of RSUs that vest pursuant to Section 1 or Section

3(a)(i), 3(b)(i) or 3(c), (ii) a “separation from service” within the meaning of Section 409A of the Code in the case of RSUs that vest pursuant to Section 3(a)(ii), 3(b)(ii) and 3(d) above and Section 9(b)(iv)(D) of the Plan and (iii) a “change in control event” within the meaning of U.S. Treasury Regulation §1.409A-3(i)(5) in the case of RSUs that vest pursuant to Section 9(b)(ii) of the Plan. Such Shares shall be fully paid and non-assessable. Participant will not have any of the rights or privileges of a shareholder of the Company in respect of any Shares subject to the RSUs unless and until such Shares have been issued to Participant.

(b) Delayed Payment

Notwithstanding Section 4(a) above, if the RSUs are considered an item of deferred compensation under Section 409A of the Code and the Shares are distributable by reason of a Participant’s separation from service during the period that Participant is both subject to U.S. federal income taxation and a “specified employee” (within the meaning of Section 409A(a)(2)(B)(i) of the Code), any Shares that would otherwise be issuable during the 6-month period immediately following Participant’s separation from service will be issued on the first day of the 7th month following Participant’s separation from service (or, if Participant dies during such period, within 30 days after Participant’s death).

5.Change in Control.

In the event of a Change in Control, the treatment of the RSUs will be governed by the terms of the Plan, subject to Section 4 above.

6.Responsibility for Taxes.

Participant acknowledges that, regardless of any action taken by the Company or, if different, Participant’s employer (the “Employer”), the ultimate liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to Participant’s participation in the Plan and legally applicable to Participant (“Tax-Related Items”) is and remains Participant’s responsibility and may exceed the amount actually withheld by the Company or the Employer. Participant further acknowledges that the Company and the Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the RSUs; and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the RSUs to reduce or eliminate Participant’s liability for Tax-Related Items or achieve any particular tax result. Further, if Participant is subject to Tax‑Related Items in more than one jurisdiction, Participant acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

To satisfy any withholding obligations of the Company and/or the Employer with respect to Tax-Related Items, the Company will withhold Shares otherwise issuable upon settlement of the RSUs. Alternatively, or in addition, in connection with any applicable taxable or tax withholding event, Participant authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following:

(a) withholding from Participant’s wages or other cash compensation paid to Participant by the Company or the Employer,

(b) withholding from proceeds of the sale of Shares acquired upon settlement of the RSUs either through a voluntary sale or through a mandatory sale arranged by the Company (on Participant’s behalf pursuant to this authorization without further consent) and/or

(c) requiring Participant to tender a cash payment to the Company or an Affiliate in the amount of the Tax-Related Items;

provided, however, that if Participant is a Section 16 officer of the Company under the Act, the withholding methods described in this Section 6 (a), (b) and (c) will only be used if the Committee (as constituted to satisfy Rule 16b-3 of the Act) determines, in advance of the applicable withholding event, that one such withholding method will be used in lieu of withholding Shares.

The Company may withhold for Tax-Related Items by considering minimum statutory withholding rates or other withholding rates, including maximum withholding rates applicable in Participant’s jurisdiction, in which case Participant may receive a refund of any over-withheld amount in cash and will have no entitlement to the equivalent amount in Shares. If the obligation for Tax-Related Items is satisfied by withholding Shares, for tax purposes, Participant is deemed to have been issued the full number of Shares subject to the vested portion of the RSUs, notwithstanding that a number of the Shares are held back solely for the purpose of paying the Tax-Related Items. The Company may refuse to issue or deliver the Shares or the proceeds of the sale of Shares, if Participant fails to comply with his or her obligations in connection with the Tax-Related Items.

7.Nature of Grant.

In accepting the RSUs, Participant acknowledges, understands and agrees that:

(a)the Plan is established voluntarily by the Company, it is discretionary in nature and it may be amended, altered or discontinued by the Company at any time, to the extent permitted by the Plan;

(b)the grant of the RSUs is voluntary and occasional and does not create any contractual or other right to receive future grants of restricted stock units, or benefits in lieu of restricted stock units, even if restricted stock units have been granted in the past;

(c)all decisions with respect to future restricted stock unit grants, if any, will be at the sole discretion of the Company;

(d)Participant is voluntarily participating in the Plan;

(e)the RSUs and the Shares subject to the RSUs, and the income and value of same, are not intended to replace any pension rights or compensation;

(f)the RSUs and the Shares subject to the RSUs, and the income and value of same, are not part of normal or expected compensation or salary for any purpose, including, but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end of service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments;

(g)unless otherwise agreed with the Company, the RSUs and the Shares subject to the RSUs, and the income and value of same, are not granted as consideration for, or in connection with, services Participant may provide as a director of an Affiliate;

(h)the RSU grant and Participant’s participation in the Plan will not create a right to employment or be interpreted as forming or amending an employment or service contract with the Company, the Employer or any Affiliate and will not interfere with the ability of

the Company, the Employer or any Affiliate, as applicable, to terminate Participant’s employment or service relationship (if any);

(i)the future value of the underlying Shares is unknown, indeterminable and cannot be predicted with certainty;

(j)no claim or entitlement to compensation or damages shall arise from forfeiture of the RSUs resulting from Participant ceasing to provide employment or other services to the Company or the Employer (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Participant is employed or the terms of Participant’s employment agreement, if any) or from cancellation of the RSUs or recoupment of any financial gain resulting from the RSUs as described in Section 13 below;

(k)for purposes of the RSUs, Participant’s employment or other service relationship will be considered terminated as of the date Participant is no longer actively providing services to the Company or one of its Affiliates (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Participant is employed or the terms of Participant’s employment agreement, if any) and, unless otherwise expressly provided in this Award Agreement or determined by the Company, Participant’s right to vest in the RSUs under the Plan, if any, will terminate as of such date, or will be measured with reference to such date in the case of a Group Termination Event, special termination or termination due to disability or death, and will not be extended by any notice period (e.g., Participant’s period of active service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where Participant is employed or the terms of Participant’s employment agreement, if any); the Committee shall have the exclusive discretion to determine when Participant is no longer actively providing services for purposes of the RSUs (including whether Participant may still be considered to be providing services while on a leave of absence);

(l)unless otherwise provided in the Plan or by the Company, in its discretion, the RSUs and the benefits evidenced by this Award Agreement do not create any entitlement to have the RSUs or any such benefits transferred to, or assumed by, another company nor to be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting the Shares; and

(m)neither the Company, nor the Employer nor any Affiliate will be liable for any foreign exchange rate fluctuation between Participant’s local currency and the United States Dollar that may affect the value of the RSUs or of any amounts due to Participant pursuant to the settlement of the RSUs or the subsequent sale of any Shares acquired upon settlement.

8.No Advice Regarding Grant.

The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding Participant’s participation in the Plan, or his or her acquisition or sale of the underlying Shares. Participant should consult with his or her own personal tax, legal and financial advisors regarding Participant’s participation in the Plan before taking any action related to the Plan.

9.Data Privacy.

a.Data Collection and Usage. The Company and the Employer may collect, process and use certain personal information about Participant, including, but not limited to, Participant’s name, home address and telephone number, email address, date of birth, social insurance number, passport or other identification number, salary, nationality, job title, any shares or directorships held in the Company, details of all RSUs granted under the Plan or any other entitlement to shares awarded, canceled, exercised, vested, unvested or outstanding in Participant’s favor (“Data”), for the purposes of implementing, administering and managing the Plan. The Company, with its registered address at Block D, Iveagh Court, Harcourt Road, Dublin 2, Ireland, acts as the data controller in respect of such Data. The legal basis, where required, for the processing of Data is Participant’s consent.

b.Stock Plan Administration Service Providers. The Company transfers Data to UBS, Broadridge Output Solutions, Inc., Cognizant Worldwide Limited, DG3, HCL Technologies Limited, Iron Mountain, Solium Capital, and Taylor Communications, which assists the Company with the implementation, administration and management of the Plan. In the future, the Company may select a different service provider and share Data with such other provider serving in a similar manner. Participant may be asked to acknowledge or (where applicable) agree to separate terms and data processing practices with the service provider, with such agreement (where applicable) being a condition to the ability to participate in the Plan.

c.International Data Transfers. The Company and its service providers are based in the United States. The legal basis, where required, for the transfer of Data is Participant’s consent.

d.Data Retention. The Company will hold and use Data only as long as is necessary to implement, administer and manage Participant’s participation in the Plan, or as required to comply with legal or regulatory obligations, including under tax, exchange control, labor and securities laws.

e.Data Subject Rights. Participant may have a number of rights under the data privacy laws in his or her jurisdiction. Depending on where Participant is based, such rights may include the right to (i) request access or copies of Data the Company processes, (ii) rectification of incorrect Data, (iii) deletion of Data, (iv) restrictions on processing of Data, (v) portability of Data, (vi) lodge complaints with competent authorities in Participant’s jurisdiction, and/or (vii) receive a list with the names and addresses of any potential recipients of Data. To receive clarification regarding these rights or to exercise these rights, Participant understands that he or she can contactDataprivacy@Allegion.com.

f.Declaration of Consent. By accepting this award of RSUs and indicating consent via the Company’s online acceptance procedure, Participant is declaring that he or she agrees with the data processing practices described herein and consents to the collection, processing and use of Data by the Company and the transfer of Data to the recipients mentioned herein, including recipients located in countries which may not have a similar level of protection from the perspective of the data protection laws in Participant’s country.

Participation in the Plan is voluntary and Participant is providing the consents described herein on a purely voluntary basis. If Participant does not consent, or if Participant later seeks to revoke his or her consent, Participant’s salary from or employment and career with the Employer will not be affected; the only consequence of refusing or withdrawing consent is that the Company would not be able to grant RSUs under the Plan to Participant or administer or maintain Participant’s participation in the Plan.

10.Electronic Delivery and Participation.

The Company may, in its sole discretion, decide to deliver any documents related to participation in the Plan by electronic means or to request Participant’s consent to participate in the Plan by electronic means. Participant hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company.

11.Insider Trading/Market Abuse Laws.

Participant may be subject to insider trading restrictions and/or market abuse laws in applicable jurisdictions including, but not limited to, the United States and Participant’s country of residence, which may affect Participant’s ability to accept, acquire, sell or otherwise dispose of Shares or rights to Shares (e.g., RSUs) or rights linked to the value of Shares under the Plan during such times as Participant is considered to have “inside information” regarding the Company (as defined by the laws in Participant’s country). Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under the Company’s insider trading policy.

12.Imposition of Other Requirements.

This grant is subject to, and limited by, all applicable laws and regulations and to such approvals by any governmental agencies or national securities exchanges as may be required. Participant agrees that the Company shall have unilateral authority to amend the Plan and this Award Agreement without Participant’s consent to the extent necessary to comply with securities or other laws applicable to the issuance of Shares. The Company reserves the right to impose other requirements on Participant’s participation in the Plan, on the RSUs and on any Shares acquired under the Plan, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to require Participant to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

13.Recoupment Provision.

In the event that Participant commits fraud or engages in intentional misconduct that results in a need for the Company to restate its financial statements, then the Committee may direct the Company to (i) cancel any outstanding portion of the RSUs and (ii) recover all or a portion of the financial gain realized by Participant through the RSUs. Further, Participant agrees that the RSUs and any financial gain realized by Participant through the RSUs shall be subject to forfeiture and/or repayment to the Company to the extent required to comply with any applicable laws or the rules and regulations of the securities exchange or inter-dealer quotation system on which the Shares are listed or quoted, including, without limitation, pursuant to Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010.

14.Choice of Law and Venue.

The RSU grant and the provisions of this Award Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without regard to such state’s conflict of laws or provisions, as provided in the Plan. For purposes of litigating any dispute that arises under this grant or this Award Agreement, the parties hereby submit to and consent to the jurisdiction of the State of Delaware and agree that such litigation shall be conducted in the courts of New Castle County, Delaware,

or the federal courts for the United States for the District of Delaware, where this grant is made and/or to be performed.

15.Severability.

The provisions of this Award Agreement are severable and if any one or more provisions are determined to be illegal or otherwise unenforceable, in whole or in part, the remaining provisions shall nevertheless be binding and enforceable.

16.Waiver.

Participant acknowledges that a waiver by the Company of breach of any provision of this Award Agreement shall not operate or be construed as a waiver of any other provision of this Award Agreement, or of any subsequent breach by Participant or any other participant in the Plan.

17.Acknowledgement of Availability of Plan Prospectus.

Participant acknowledges that he or she has been provided with access to a copy of the Plan prospectus and Plan document, links to both of which are available below:

[EMBED LINK TO PLAN PROSPECTUS] [EMBED LINK TO PLAN DOCUMENT]

This grant is subject to acceptance, within 120 days of the Grant Date, by electronic acceptance through the website of UBS, the Company’s stock plan administrator. Failure to accept the RSUs within 120 days of the Grant Date may result in cancellation of the RSUs.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A summary of significant accounting policies used in the preparation of the accompanying Consolidated Financial Statements follows:

Principles of Consolidation: The Consolidated Financial Statements include all controlled subsidiaries of the Company. A noncontrolling interest in a subsidiary is considered an ownership interest in a controlled subsidiary that is not attributable to the Company. The Company includes noncontrolling interests as a component of Total equity in the Consolidated Balance Sheets and the Net earnings attributable to noncontrolling interests are presented as an adjustment from Net earnings used to arrive at Net earnings attributable to Allegion plc in the Consolidated Statements of Comprehensive Income.

Equity method affiliates represent unconsolidated entities over which the Company demonstrates significant influence but does not have a controlling financial interest. The Company is also required to consolidate variable interest entities in which it bears a majority of the risk to the entity’s potential losses or stands to gain from a majority of the entity’s expected returns.

Use of Estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Estimates are based on several factors including the facts and circumstances available at the time the estimates are made, historical experience, risk of loss, general economic conditions and trends and the assessment of the probable future outcome. Some of the more significant estimates include useful lives of property, plant and equipment and intangible assets, purchase price allocations of acquired businesses, valuation of assets and liabilities including goodwill and other intangible assets, product warranties, sales allowances, pension plan benefits, postretirement benefits other than pensions, taxes, lease related assets and liabilities, environmental costs and product liability and other contingencies. Actual results could differ from those estimates. Estimates and assumptions are reviewed periodically, and the effects of changes, if any, are reflected in the Consolidated Statements of Comprehensive Income in the period they are determined.

Currency Translation: Assets and liabilities where the functional currency is not the U.S. dollar have been translated at year-end exchange rates, and income and expense accounts have been translated using average exchange rates throughout the year. Adjustments resulting from the process of translating a subsidiary’s financial statements into the U.S. dollar are recorded to Accumulated other comprehensive loss.

Cash and Cash Equivalents: Cash and cash equivalents include cash on hand, demand deposits and all highly liquid investments with original maturities at the time of purchase of three months or less.

Allowance for Doubtful Accounts: The Company provides for an allowance for doubtful accounts and notes receivable, which represents the best estimate of expected lifetime credit losses inherent in the Company’s accounts and notes receivable portfolios. The Company's estimates are influenced by a continuing credit evaluation of customers' financial condition, trade accounts and notes receivable aging and historical loss experience, as well as reasonable and supportable forecasts of future economic conditions. The Company has reserved $6.2 million and $5.6 million for doubtful accounts and notes receivable as of December 31, 2020 and 2019, respectively.

Inventories: Inventories are stated at the lower of cost and net realizable value using the first-in, first-out (FIFO) method.

Property, Plant and Equipment: Property, plant and equipment are stated at cost, less accumulated depreciation. Assets placed in service are recorded at cost and depreciated using the straight-line method over the estimated useful life of the asset except for leasehold improvements, which are depreciated over the shorter of their economic useful life or their lease term. Repair and maintenance costs that do not extend the useful life of the asset are expensed as incurred. Major replacements and significant improvements that increase asset values and extend useful lives are capitalized. The range of useful lives used to depreciate property, plant and equipment is as follows:

Buildings	10	to	50	years
Machinery and equipment	2	to	12	years
Software	2	to	7	years

The Company assesses the recoverability of the carrying value of its property, plant and equipment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be fully recoverable. Recoverability is measured by a comparison of the carrying amount of an asset to the future net undiscounted cash flows expected to be generated by the asset. If the undiscounted cash flows are less than the carrying amount of the asset, an impairment loss is recognized for the amount by which the carrying value of the asset exceeds its fair value.

Investments: The Company periodically invests in debt or equity securities of start-up companies and/or development stage technology or other companies without acquiring a controlling interest. The Company applies the equity method of accounting when the Company has the ability to exercise significant influence over the operating and financial decision making of the investee. Investments in equity method affiliates totaled $17.4 million and $18.2 million as of December 31, 2020 and 2019, respectively. Equity investments that have readily determinable fair values in which the Company does not have significant influence are measured at fair value, with any unrealized holding gains and losses being recorded to earnings. Investments without readily determinable fair values are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer and are qualitatively assessed for impairment indicators each reporting period. Investments in debt and equity securities not accounted for under the equity method of accounting totaled $13.7 million and $18.1 million as of December 31, 2020 and 2019, respectively. The Company's investments are principally recorded within Other noncurrent assets within the Consolidated Balance Sheets.

Leases: In accordance with ASC 842, the Company records a right-of-use ("ROU") asset and lease liability for substantially all leases for which it is a lessee. In determining if a contract represents a lease, consideration is given to all relevant facts and circumstances to assess whether or not the contract conveys the right to control the use of an identified asset, either explicit or implicit, for a period of time in exchange for consideration. Judgment and estimation is also required in determining the lease classification and the amount of the ROU asset and corresponding lease liability for each lease, which includes determining the appropriate lease term and an applicable discount rate. The Company assesses the specific terms and conditions of each lease to determine the appropriate classification as either an operating or finance lease. In determining the appropriate length of the lease term, both the minimum period over which lease payments are required plus any renewal options that are both within the Company's control to exercise and reasonably certain of being exercised as of lease commencement are considered. When available, the rate implicit in the lease is utilized as the discount rate to determine the lease liability. If this rate is unavailable, the Company utilizes its incremental borrowing rate as the discount rate, which is the rate at inception of the lease that would hypothetically be incurred to borrow over a similar term the funds needed to purchase the leased asset. Refer to Note 11 for further details on the Company's lease accounting policies.

Goodwill and Intangible Assets: The Company records as goodwill the excess of the purchase price of an acquired business over the fair value of the net assets acquired. Once the final valuation has been performed for each acquisition, adjustments may be recorded. In accordance with ASC 350, "Intangibles—Goodwill and Other", goodwill and other indefinite-lived intangible assets are tested and reviewed annually for impairment during the fourth quarter or whenever there is a significant change in events or circumstances that indicate the fair value of a reporting unit or indefinite-lived intangible asset is more likely than not less than the carrying amount of the asset.

Recoverability of goodwill is measured at the reporting unit level. The carrying amount of a reporting unit is compared to its estimated fair value. If the estimated fair value of a reporting unit exceeds it's carrying amount, goodwill of the reporting unit is not impaired. To the extent that the carrying value of the reporting unit exceeds its estimated fair value, a goodwill impairment charge will be recognized for the amount by which the carrying value of the reporting unit exceeds its fair value, not to exceed the carrying amount of the reporting unit's goodwill. Estimated fair value of the Company's reporting units is based on two valuation techniques, a discounted cash flow model (income approach) and a market multiple of earnings (market approach), with each method being weighted in the calculation.

As a result of the global economic disruption and uncertainty due to the novel coronavirus ("COVID-19") pandemic, the Company concluded a triggering event had occurred as of March 31, 2020, and accordingly, performed interim impairment tests on the goodwill balances of its EMEA and Asia Pacific reporting units. Given the high degree of market volatility and lack of reliable market data that existed as of March 31, 2020, the Company determined a discounted cash flow model (income approach) provided the best approximation of fair value of these reporting units for the purpose of performing these interim tests. This was a change in estimate, as historically the determination of reporting unit fair values has been estimated based on both an income and a market approach, as discussed above, with each method being weighted in the calculation. As markets stabilized throughout the year, the Company reverted to utilizing both an income and market approach while performing its annual impairment test in the fourth quarter.

Recoverability of other intangible assets with indefinite useful lives (i.e. Trade names) is determined on a relief from royalty methodology, which is based on the implied royalty paid, at an appropriate discount rate, to license the use of an asset rather than owning the asset. The present value of the after-tax cost savings (i.e. royalty relief) indicates the estimated fair value of the asset. Any excess of the carrying value over the estimated fair value is recognized as an impairment loss equal to that excess.

Intangible assets such as completed technologies, patents, customer-related intangible assets and other intangible assets with finite useful lives are amortized on a straight-line basis over their estimated economic lives. The weighted-average useful lives approximate the following:

Customer relationships	20	years
Trade names (finite-lived)	25	years
Completed technologies/patents	10	years
Other	7	years

Recoverability of intangible assets with finite useful lives is assessed in the same manner as property, plant and equipment, as described above.

Income Taxes: The calculation of the Company’s income taxes involves considerable judgment and the use of both estimates and allocations. Deferred tax assets and liabilities are determined based on temporary differences between financial reporting and tax bases of assets and liabilities, applying enacted tax rates expected to be in effect for the year in which the differences are expected to reverse. The Company recognizes future tax benefits, such as net operating losses and tax credits, to the extent that realizing these benefits is considered in its judgment to be more likely than not. The Company regularly reviews the recoverability of its deferred tax assets considering its historic profitability, projected future taxable income, timing of the reversals of existing temporary differences and the feasibility of its tax planning strategies. Where appropriate, the Company records a valuation allowance with respect to future tax benefits.

Cash paid for income taxes, net of refunds, for the twelve months ended December 31, 2020 and 2019 was $82.6 million and $103.0 million, respectively.

Product Warranties: The Company offers a standard warranty with most product sales, and the value of such warranty is included in the contractual sales price. Standard product warranty accruals are recorded at the time of sale and are estimated based upon product warranty terms and historical experience. The Company regularly assesses the adequacy of its liabilities and makes adjustments as necessary based on known or anticipated warranty claims, or as new information becomes available. Refer to Note 21 for further details regarding product warranties.

Revenue Recognition: Net revenues are recognized based on the satisfaction of performance obligations under the terms of a contract. A performance obligation is a promise in a contract to transfer control of a distinct product or to provide a service, or a bundle of products or services, to a customer. The Company has two principal revenue streams, tangible product sales and services. Approximately 99% of consolidated Net revenues involve contracts with a single performance obligation, the transfer of control of a product or bundle of products to a customer. The Company's remaining Net revenues involve services, including installation and consulting. See Note 20 for additional information regarding the Company's revenue recognition policies.

Sales returns and customer disputes involving a question of quantity or price are accounted for as variable consideration, and therefore, as a reduction to Net revenues and as a contra receivable. At December 31, 2020 and 2019, the Company had a customer claim accrual (contra receivable) of $48.6 million and $36.5 million, respectively. All other incentives or incentive programs where the customer is required to reach a certain level of purchases, remain a customer for a certain period, provide a rebate form or is subject to additional requirements are also considered variable consideration and are accounted for as a reduction of revenue and a liability. At December 31, 2020 and 2019, the Company had a sales incentive accrual of $35.0 million and $37.2 million, respectively. Variable consideration is estimated based on the most likely amount expected to be

received from customers. Each of these accruals represents the Company’s best estimate of the most likely amount expected to be received from customers based on historical experience. These estimates are reviewed regularly for accuracy, and if updated information or actual amounts are different from previous estimates, the revisions are included in the Company’s results for the period in which they become known. Historically, the aggregate differences, if any, between the Company’s estimates and actual amounts in any year have not had a material impact on the Consolidated Financial Statements. The Company also offers a standard warranty with most product sales, and the value of such warranty is included in the contractual price. The corresponding cost of the warranty obligation is accrued as a liability.

Environmental Costs: The Company is subject to laws and regulations relating to protecting the environment. Environmental expenditures relating to current operations are expensed or capitalized as appropriate. Expenditures relating to existing conditions caused by past operations, which do not contribute to current or future revenues, are expensed. Liabilities for remediation costs are recorded when they are probable and can be reasonably estimated, generally no later than the completion of feasibility studies or the Company’s commitment to a plan of action. The assessment of this liability, which is calculated based on existing technology, does not reflect any offset for possible recoveries from insurance companies and is not discounted. Refer to Note 21 for further details related to environmental matters.

Research and Development Costs: The Company conducts research and development activities for the purpose of developing and improving new products and services. These costs are expensed when incurred. For the years ended December 31, 2020, 2019 and 2018, expenses related to research and development activities amounted to approximately $54.4 million, $54.7 million and $54.4 million, respectively, and primarily consist of salaries, wages, benefits, facility costs and other overhead expenses.

Defined Benefit Plans: The Company provides a range of defined benefits, including pension, postretirement and postemployment benefits to eligible current and former employees. Determining the costs associated with such benefits is dependent on various actuarial assumptions, including discount rates, expected return on plan assets, compensation increases, employee mortality and turnover rates. Actuaries perform the required calculations to determine expense in accordance with GAAP. Actual results may differ from the actuarial estimates and are generally recorded to Accumulated other comprehensive loss and amortized into Net earnings over future periods. The Company reviews its actuarial assumptions at each measurement date and makes modifications to the assumptions as appropriate. Refer to Note 12 for further details on employee benefit plans.

Loss Contingencies: Liabilities are recorded for various contingencies arising in the normal course of business, including litigation and administrative proceedings, environmental matters, product liabilities, product warranties, worker’s compensation and other claims. The Company has recorded reserves in the financial statements related to these matters, which are developed using inputs derived from actuarial estimates and historical and anticipated experience data depending on the nature of the reserve and, in certain instances, with consultation of legal counsel, internal and external consultants and engineers. Subject to the uncertainties inherent in estimating future costs for these types of liabilities, the Company believes its estimated reserves are reasonable and does not believe the final determination of the liabilities with respect to these matters would have a material effect on the financial condition, results of operations, liquidity or cash flows of the Company for any year. Refer to Note 21 for further details related to loss contingencies.

Derivative Instruments: The Company periodically enters into cash flow and other derivative transactions to specifically hedge exposure to various risks related to currency and variable interest rates. The Company recognizes all derivatives on the Consolidated Balance Sheets at their fair value as either assets or liabilities. For designated cash flow hedges, the changes in fair value of the derivative contract is recorded to Accumulated other comprehensive loss and reclassified into Net earnings at the time earnings are affected by the hedged transaction. For undesignated derivative transactions, the changes in the fair value of the derivative contract are immediately recognized in Net earnings. Refer to Note 10 for further details regarding derivative instruments.

Recent Accounting Pronouncements

Recently Adopted Accounting Pronouncements:

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." The new guidance within ASU 2016-13, along with related updates (collectively "ASC 326") introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. The new guidance became effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods. Accordingly, the Company adopted ASC 326 on January 1, 2020, using the modified retrospective transition method through a $2.2 million cumulative-effect decrease to retained earnings. The Company has also made updates to its policies and internal controls over financial reporting as a result of adoption.

In August 2018, the FASB issued ASU 2018-15, "Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." The new guidance aligns the requirements for capitalizing implementation costs incurred in a cloud-based hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 became effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods. Accordingly, the Company adopted ASU 2018-15 on January 1, 2020, using the prospective method of adoption, and the adoption did not have a material impact to the Consolidated Financial Statements.

Recently Issued Accounting Pronouncements:

In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." The new guidance is intended to simplify the accounting for income taxes by removing certain exceptions and by updating accounting requirements around franchise taxes, goodwill recognized for tax purposes, the allocation of current and deferred tax expense among legal entities, among other minor changes. The ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted. The Company adopted ASU 2019-12 on January 1, 2021, and the adoption did not have a material impact to the Consolidated Financial Statements.

In January 2020, the FASB issued ASU 2020-01, "Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815." The amendments in ASU 2020-01 clarify the interaction of the accounting for equity securities under Topic 321 and investments accounted for under the equity method of accounting. The ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted. The Company adopted ASU 2020-01 on January 1, 2021, and the adoption did not have a material impact to the Consolidated Financial Statements.

In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." This ASU, along with related updates, provides temporary optional expedients and exceptions for applying GAAP to contract modifications, hedging relationships and other transactions if certain criteria are met in order to ease the potential accounting and financial reporting burden associated with the expected market transition away from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. The ASU is currently effective and may be applied prospectively at any point through December 31, 2022 at the Company’s option. The Company is assessing what impact ASU 2020-04 will have on the Consolidated Financial Statements.

(a)     In 2019, the Company made reclassifications to goodwill across all segments related to a change in how revenue is managed for a specific immaterial product line where revenue previously managed in the Asia Pacific segment is now being managed in the Americas and EMEA segments.

As a result of the global economic disruption and uncertainty due to the COVID-19 pandemic, the Company concluded a triggering event had occurred as of March 31, 2020, and accordingly, performed interim impairment tests on the goodwill balances of its EMEA and Asia Pacific reporting units. As quoted market prices were not available for these reporting units, and given the high degree of market volatility and lack of reliable market data that existed as of March 31, 2020, the Company determined that a discounted cash flow model (income approach) provided the best approximation of fair value of its EMEA and Asia Pacific reporting units for the purpose of performing these interim tests. This approach relied on numerous assumptions and judgments that were subject to various risks and uncertainties. Principal assumptions utilized, all of which are considered Level 3 inputs under the fair value hierarchy (see Note 13), included the Company’s estimates of future revenue and terminal growth rates, margin assumptions and discount rates to estimate future cash flows. The calculations explicitly addressed factors such as timing, with due consideration given to forecasting risk. While assumptions utilized were subject to a high degree of judgment and complexity, the Company made every effort to estimate future cash flows as accurately as possible, given the high degree of economic uncertainty that existed as of March 31, 2020. The results of the interim impairment testing indicated that the estimated fair value of the Asia Pacific reporting unit was less than its carrying value. Consequently, a goodwill impairment charge was recorded for the Asia Pacific reporting unit, as reflected in the table above. As markets stabilized throughout the year, the Company reverted to utilizing both an income and market approach while performing its annual impairment test in the fourth quarter, which resulted in no further impairment charges.

Total	$	710.9			$	487.1	$	695.1			$	510.9

The Company amortizes finite-lived intangible assets on a straight-line basis over their estimated economic lives in accordance with GAAP. Indefinite-lived intangible assets are not subject to amortization, but instead are tested for impairment at least annually (more frequently if certain indicators are present). Intangible asset amortization expense for the years ended 2020, 2019 and 2018, was $31.5 million, $31.2 million and $36.3 million, respectively. Intangible asset amortization expense for 2018 included the amortization of approximately $6 million of backlog revenue that was acquired during an acquisition. Future estimated amortization expense on existing intangible assets in each of the next five years amounts to approximately $28.5 million for 2021, $28.5 million for 2022, $28.4 million for 2023, $28.3 million for 2024 and $27.4 million for 2025.

In accordance with the Company’s indefinite-lived intangible asset impairment testing policy, the Company performs its annual impairment test in the fourth quarter of each year or whenever there is a significant change in events or circumstances that indicate the fair value of an indefinite-lived intangible asset is more likely than not less than its carrying amount. As a result of the global economic disruption and uncertainty due to the COVID-19 pandemic, the Company concluded a triggering event had occurred as of March 31, 2020, and accordingly, performed interim impairment testing on certain indefinite-lived trade names. Based on these tests, it was determined that three of the Company's indefinite-lived trade names in the EMEA and Asia Pacific segments were impaired, and impairment charges of $8.2 million were recorded. Further intangible asset impairment charges were recorded in the Asia Pacific segment during the year ended December 31, 2020, including $2.6 million relating to supply chain disruptions, which reduced a brand's expected future cash flows, and $2.8 million related to declines in volumes and pricing pressure for a separate subsidiary in the region.

During the 2019 annual impairment testing, it was determined that two of the Company's indefinite-lived trade names were impaired, resulting in impairment charges totaling $5.9 million. No intangible asset impairment charges were recorded in 2018.

Divestitures	DIVESTITURESAs of December 31, 2020, the net assets of the Company's QMI business, which primarily included working capital and long-lived assets, met the criteria to be classified as held for sale, and accordingly, were written down to fair value, which was estimated based on expected sales proceeds, less cost to sell, in accordance with ASC 360. This remeasurement was based on inputs considered to be Level 3 inputs under the fair value hierarchy (see Note 13) and resulted in a Loss on assets held for sale of $37.9 million. As the expected sales proceeds, less cost to sell, were nominal, no goodwill was allocated to the Assets held for sale, and the goodwill attributable to the 2018 acquisition of QMI remains in the EMEA reporting unit as of December 31, 2020.In 2019, the Company closed its production facility in Turkey and sold certain of the production assets thereof, which collectively met the definition of a business under ASC 805. Total proceeds from the sale were approximately $4.1 million, and the Company recorded a loss on divestiture of $24.2 million ($25.5 million, net of tax), primarily driven by the reclassification of $25.0 million of accumulated foreign currency translation adjustments to earnings upon sale. The Company also sold its interests in its Colombia operations in 2019 for a nominal amount, recording a net loss on divestiture of $5.9 million, of which $1.2 million relates to the reclassification of accumulated foreign currency translation adjustments to earnings upon sale. These losses are included within Loss on divestitures in the Consolidated Statements of Comprehensive Income.

Unsecured Credit Facilities

As of December 31, 2020, the Company has an unsecured Credit Agreement in place, consisting of a $700.0 million term loan facility (the “Term Facility”), of which $238.8 million is outstanding at December 31, 2020, and a $500.0 million revolving credit facility (the “Revolving Facility” and, together with the Term Facility, the “Credit Facilities”). The Credit Facilities mature on September 12, 2022, and are unconditionally guaranteed jointly and severally on an unsecured basis by the Company and Allegion US Holding Company Inc. ("Allegion US Hold Co"), the Company's wholly-owned subsidiary.

At inception, the Term Facility was scheduled to amortize in quarterly installments at the following rates: 1.25% per quarter starting December 31, 2017 through December 31, 2020, 2.5% per quarter from March 31, 2021 through June 30, 2022, with the balance due on September 12, 2022. Principal amounts repaid on the Term Facility may not be reborrowed. During the third quarter of 2019, the Company made a $400.0 million principal payment to partially pay down the outstanding Term Facility balance. As a result of this payment, the Company has satisfied its obligation to make quarterly installments on the Term Facility up to the maturity date, with the remaining outstanding balance due on September 12, 2022. In conjunction with this principal pay down, the Company recognized a $2.7 million charge related to the write-off of previously deferred financing

costs related to the Term Facility, which is included in Interest expense in the Consolidated Statement of Comprehensive Income for the year ended December 31, 2019.

The Revolving Facility provides aggregate commitments of up to $500.0 million, which includes up to $100.0 million for the issuance of letters of credit. At December 31, 2020, there were no borrowings outstanding on the Revolving Facility and the Company had $15.0 million of letters of credit outstanding. Commitments under the Revolving Facility may be reduced at any time without premium or penalty, and amounts repaid may be reborrowed. The Company pays certain fees with respect to the Revolving Facility, including an unused commitment fee on the undrawn portion of the Revolving Facility of between 0.125% and 0.200% per year, depending on the Company's credit rating, as well as certain other fees.

Outstanding borrowings under the Credit Facilities accrue interest at the option of the Company of (i) a LIBOR rate plus the applicable margin or (ii) a base rate plus the applicable margin. The applicable margin ranges from 1.125% to 1.500% depending on the Company's credit ratings. At December 31, 2020, the outstanding borrowings under the Term Facility accrue interest at LIBOR plus a margin of 1.250%, resulting in an interest rate of 1.51%. The Credit Facilities also contain negative and affirmative covenants and events of default that, among other things, limit or restrict the Company’s ability to enter into certain transactions. In addition, the Credit Facilities require the Company to comply with a maximum leverage ratio and a minimum interest expense coverage ratio, as defined within the agreement. As of December 31, 2020, the Company was in compliance with all covenants.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Financial instruments

FINANCIAL INSTRUMENTSIn the normal course of business, the Company uses various financial instruments, including derivative instruments, to manage the risks associated with variable interest and currency rate exposures. These financial instruments are not used for trading or speculative purposes. When a derivative contract is entered into, the Company designates the derivative instrument as a cash flow hedge of a forecasted transaction, a cash flow hedge of a recognized asset or liability or as an undesignated derivative. The Company formally documents its hedge relationships, including identification of the derivative instruments and the hedged

items, as well as its risk management objectives and strategies for undertaking the hedge transaction. This process includes linking derivative instruments that are designated as hedges to specific assets, liabilities or forecasted transactions.

The Company assesses at inception and at least quarterly thereafter, whether the derivatives used in cash flow hedging transactions are effective in offsetting the changes in the cash flows of the hedged item. To the extent the derivative is deemed to be an effective hedge, the fair market value changes of the instrument are recorded to Accumulated other comprehensive loss, while changes in the fair market value of derivatives not deemed to be an effective hedge are recorded in Net earnings in the period of change. The fair market value of derivative instruments is determined through market-based valuations and may not be representative of the actual gains or losses that will be recorded when these instruments mature due to future fluctuations in the markets in which they are traded. If the hedging relationship ceases to be effective subsequent to inception, or it becomes probable that a forecasted transaction will longer occur, the hedging relationship will be undesignated and any future gains or losses on the derivative instrument will be recorded in Net earnings.

Currency Derivatives

The gross notional amount of the Company’s currency derivatives was $218.9 million and $146.4 million at December 31, 2020 and 2019, respectively. At December 31, 2020 and 2019, both the losses included in Accumulated other comprehensive loss and the amount expected to be reclassified into Net earnings over the next twelve months related to the Company’s currency derivatives designated as cash flow hedges were not material, although the actual amounts that will be reclassified to Net earnings may vary as a result of future changes in market conditions. Gains and losses associated with the Company’s currency derivatives not designated as hedges are recorded in Net earnings as changes in fair value occur. At December 31, 2020, the maximum term of the Company’s currency derivatives was less than one year.

Interest Rate Swaps

As of December 31, 2019, and through their expiration in September 2020, the Company had interest rate swaps to fix the interest rate paid during the contract period related to $200.0 million of the Company's variable rate Term Facility. Prior to expiration, these swaps met the criteria to be accounted for as cash flow hedges of variable rate interest payments.

The fair values of derivative instruments included within the Consolidated Balance Sheets as of December 31, 2020 and 2019 were not material. The amounts associated with derivatives designated as hedges affecting Net earnings and Accumulated other comprehensive loss for the years ended December 31 were as follows:

	Amount of gain (loss) recognized in Accumulated other comprehensive loss						Location of gain recognized in Net earnings	Amount of gain reclassified from Accumulated other comprehensive loss and recognized into Net earnings

Leases [Abstract]

Leases Disclosure

LEASESThe Company adopted ASC 842 on January 1, 2019, utilizing the transition method allowed per ASU 2018-11. Financial information for the year ended December 31, 2018, has not been adjusted for the effects of adopting ASC 842, and no cumulative-effect adjustment was required to the opening balance of Retained earnings on the adoption date. In accordance with ASC 842, the Company records a right-of-use ("ROU") asset and lease liability for substantially all leases for which it is a lessee. At inception of a contract, the Company considers all relevant facts and circumstances to assess whether or not the

contract represents a lease by determining whether or not the contract conveys the right to control the use of an identified asset, either explicit or implicit, for a period of time in exchange for consideration. The Company has no significant lease agreements in place for which the Company is a lessor, and substantially all of the Company's leases for which the Company is a lessee are classified as operating leases. Total rental expense for the years ended December 31, 2020 and 2019, was $44.2 million and $43.2 million, respectively, and is classified within Cost of goods sold and Selling and administrative expenses within the Consolidated Statements of Comprehensive Income. Rental expense related to short-term leases, variable lease payments or other leases or lease components not included within the ROU asset or lease liability totaled $9.1 million and $8.1 million, respectively, for the years ended December 31, 2020 and 2019. No material lease costs have been capitalized on the Consolidated Balance Sheets as of December 31, 2020 or 2019. Total rental expense for 2018, as determined in accordance with the previous lease guidance, ASC 840, was $42.5 million and is classified within Cost of goods sold and Selling and administrative expenses within the Consolidated Statements of Comprehensive Income.

If at lease commencement a lease has a term of less than 12 months and does not include a purchase option that is reasonably certain to be exercised, the Company does not include the lease as part of its ROU asset or lease liability. If the Company enters into a large number of leases in the same month with the same terms and conditions, these are considered a group (portfolio), assuming the lease model under this approach does not materially differ from applying ASC 842 to each individual lease. When available, the Company will utilize the rate implicit in the lease as the discount rate to determine the lease liability. However, as this rate is not available for most leases, the Company will use its incremental borrowing rate as the discount rate, which is the rate at inception of the lease the Company would hypothetically incur to borrow over a similar term the funds needed to purchase the leased asset.

As a lessee, the Company categorizes its leases into two general categories: real estate and equipment leases.

The Company’s real estate leases include leased production and assembly facilities, warehouses and distribution centers, office space and to a lesser degree, employee housing. The terms and conditions of real estate leases can vary significantly from lease to lease. The Company has assessed the specific terms and conditions of each real estate lease to determine the amount of the lease payments and the length of the lease term, which includes the minimum period over which lease payments are required plus any renewal options that are both within the Company's control to exercise and reasonably certain of being exercised upon lease commencement. The Company assesses all relevant factors to determine if sufficient incentives exist as of lease commencement to conclude whether or not renewal is reasonably certain. There are no material residual value guarantees provided by the Company nor any restrictions or covenants imposed by the real estate leases to which the Company is a party. In determining the lease liability, the Company utilizes its incremental borrowing rate for debt instruments with terms approximating the weighted-average term for its real estate leases to discount the future lease payments over the lease term to present value. The Company does incur variable lease payments for certain of its real estate leases, such as reimbursements of property taxes, maintenance and other operational costs to the lessor. In general, these variable lease payments are not captured as part of the lease liability or ROU asset, but rather are expensed as incurred.

The Company’s equipment leases include vehicles, material handling equipment, other machinery and equipment utilized in the Company's production and assembly facilities, warehouses and distribution centers, laptops and other IT equipment, and other miscellaneous leased equipment. Most of the equipment leases are for terms ranging from two to five years, although terms and conditions can vary from lease to lease. The Company applies similar estimates and judgments to its equipment lease portfolio in determining the lease payments and lease term as it does to its real estate lease portfolio. There are no material residual value guarantees provided by the Company nor any restrictions or covenants imposed by the equipment leases to which the Company is a party. In determining the lease liability, the Company utilizes its incremental borrowing rate for debt instruments with terms approximating the weighted-average term for its equipment leases to discount the future lease payments over the lease term to present value. The Company does not typically incur variable lease payments related to its equipment leases.

Amounts included within the Consolidated Balance Sheets related to the Company's ROU asset and lease liability were as follows:

The Company frequently enters into both real estate and equipment leases in the normal course of business. While there have been lease agreements entered into that have not yet commenced as of December 31, 2020, none of these leases provide new rights or obligations to the Company that are material individually or in the aggregate.

Future Repayments

Future minimum rental commitments for the subsequent five years under non-cancellable operating leases with terms in excess of one year as of December 31, 2018 were as follows:

Total	$	30.4	$	23.6	$	14.6	$	9.7	$	7.1	$	19.5	$	104.9

The difference between the total undiscounted minimum lease payments and the combined current and noncurrent lease liabilities as of December 31, 2020, is due to imputed interest of $11.0 million.

Retirement Benefits, Description [Abstract]

Pensions and Postretirement Benefits Other Than Pensions

PENSIONS AND POSTRETIREMENT BENEFITS OTHER THAN PENSIONSThe Company sponsors several U.S. defined benefit and defined contribution plans covering substantially all U.S. employees. Additionally, the Company has non-U.S. defined benefit and defined contribution plans covering eligible non-U.S. employees. Postretirement benefits, other than pensions, provide healthcare benefits, and in some instances, life insurance benefits for certain eligible employees.

Pension Plans

The noncontributory defined benefit pension plans covering non-collectively bargained U.S. employees provide benefits on an average pay formula, while most plans for collectively bargained U.S. employees provide benefits on a flat dollar benefit formula. The non-U.S. pension plans generally provide benefits based on earnings and years of service. The Company also maintains additional other supplemental plans for officers and other key employees.

The following table details information regarding the Company’s pension plans at December 31:

It is the Company’s objective to contribute to the pension plans to ensure adequate funds are available in the plans to make benefit payments to plan participants and beneficiaries when required. However, certain plans are not funded due to either legal, accounting or tax requirements in certain jurisdictions. As of December 31, 2020, approximately 6% of the Company's projected benefit obligation relates to plans that are not funded, of which the majority are non-U.S. plans.

The accumulated benefit obligation for all U.S. defined benefit pension plans was $354.9 million and $332.4 million at December 31, 2020 and 2019, respectively. The accumulated benefit obligation for all non-U.S. defined benefit pension plans was $446.0 million and $396.7 million at December 31, 2020 and 2019, respectively.

The Company estimates the service and interest cost components of net periodic benefit cost utilizing a full yield-curve approach. Under this approach, the Company applies discounting using the applicable spot rates derived from the yield curve to discount the cash flows used to measure the benefit obligation. These spot rates align to each of the projected benefit obligations and service cost cash flows.

The Service cost component of Net periodic pension benefit cost (income) is recorded in Cost of goods sold and Selling and administrative expenses within the Consolidated Statements of Comprehensive Income. The remaining components are recorded within Other (income) expense, net within the Consolidated Statements of Comprehensive Income.

Pension expense for 2021 is projected to be approximately $1.8 million, utilizing the assumptions for calculating the pension benefit obligations at the end of 2020.

Weighted-average assumptions used:

Net periodic pension cost for the year ended December 31,	2020		2019		2018
Discount rate:
U.S. plans	3.3	%	4.3	%	3.6	%
Non-U.S. plans	1.9	%	2.8	%	2.5	%
Rate of compensation increase:

Expected return on plan assets:
U.S. plans	5.0	%	5.0	%	5.3	%
Non-U.S. plans	3.3	%	3.8	%	4.0	%

The expected return on plan assets reflects the average rate of returns expected on the funds invested or to be invested to provide for the benefits included in the projected benefit obligation and is based on what is achievable given the plan’s investment policy, the types of assets held and target asset allocations. The expected long-term rate of return is determined as of the measurement date. Each plan is reviewed, along with its historical returns and target asset allocations, to determine the appropriate expected return on plan assets to be used.

The Company's overall objective in managing defined benefit plan assets is to ensure that all present and future benefit obligations are met as they come due. The goal is to achieve this while trying to mitigate volatility in plan funded status, contributions and expense by better matching the characteristics of the plan assets to that of the plan liabilities. Each plan’s funded status and asset allocation is monitored regularly in addition to investment manager performance.

No material transfers in or out of Level 3 occurred during the years ended December 31, 2020 or 2019.

The Company's U.S. pension plan assets are valued using the following methodologies:

•Cash, cash equivalents and short-term investments – Short-term investments are valued at their daily net asset value (NAV) per share or the equivalent based upon the fair value of the underlying investments. NAV per share or the

equivalent is used for fair value purposes as a practical expedient and is calculated by the investment manager or sponsor of the fund. These investments primarily consist of short-term investment funds.

•Common collective trusts - Common collective trust ("CCT") funds are not publicly traded and are valued at NAV per share or the equivalent based upon the fair value of the underlying investments. NAV per share or the equivalent is used for fair value purposes as a practical expedient and is calculated by the investment manager or sponsor of the applicable fund. CCT funds consist of a variety of publicly traded securities, including equity mutual funds, U.S. government and agency obligations, corporate and non-U.S. bonds, securitized credit and emerging market debt. There are no unfunded commitments, redemption frequency restrictions or other redemption restrictions related to such investments.

The Company's non-U.S. pension plan assets are valued using the following methodologies:

•Cash, cash equivalents and short-term investments – Cash equivalents are valued using a market approach with inputs including quoted market prices for either identical or similar instruments. Short-term investments are valued at the closing price or amount held on deposit by the custodian bank, at fair value by discounting the related cash flows based on current yields of similar instruments with comparable durations considering the credit-worthiness of the issuer, or at their NAV per share or the equivalent based upon the fair value of the underlying investments. NAV per share or the equivalent is used for fair value purposes as a practical expedient and is calculated by the investment manager or sponsor of the fund. These investments primarily consist of short-term investment funds.

•Equity mutual funds – Equity mutual funds are primarily valued at their NAV per share or the equivalent. NAV per share or the equivalent is used for fair value purposes as a practical expedient. NAV is calculated by the investment manager or sponsor of the fund.

•Corporate and non-U.S. bonds – Quoted market prices are not available for these securities. Fair values are either estimated using pricing models and/or quoted prices of securities with similar characteristics or discounted cash flows, in which instances such securities are classified as Level 2 or valued at their NAV per share or the equivalent. NAV

per share or the equivalent is used for fair value purposes as a practical expedient and are calculated by the investment manager or sponsor of the fund.

The Company made employer contributions of $6.3 million, $6.0 million and $6.1 million to the U.S. pension plans in 2020, 2019 and 2018, respectively. The Company made required and discretionary contributions to its non-U.S. pension plans of $5.1 million, $10.6 million and $5.4 million in 2020, 2019 and 2018, respectively.

The Company currently projects that approximately $11.4 million will be contributed to its U.S and non-U.S. plans in 2021. The Company’s policy allows it to fund an amount, which could be in excess of or less than the pension cost expensed, subject to the limitations imposed by current tax regulations. The Company anticipates funding the plans in 2021 in accordance with contributions required by funding regulations or the laws of each jurisdiction.

Most of the Company’s U.S. employees are covered by defined contribution plans. Employer contributions are determined based on criteria specific to the individual plans and amounted to approximately $17.9 million, $15.6 million and $14.4 million in 2020, 2019 and 2018, respectively. The Company’s contributions relating to non-U.S. defined contribution plans and other non-U.S. benefit plans were $7.0 million, $6.0 million and $8.0 million in 2020, 2019 and 2018, respectively.

Deferred Compensation Plan

The Company maintains an Executive Deferred Compensation Plan ("EDCP"), which is an unfunded, nonqualified plan that, prior to 2019, permitted certain employees to defer up to 50% of their annual salary and up to 100% of their annual bonus awards, performance stock plan awards and restricted stock units earned until conclusion of their employment with the Company. As of December 31, 2020 and 2019, the deferred compensation liability balance was $18.1 million and $17.4 million, respectively, which was recorded within Postemployment and other benefit liabilities in the Consolidated Balance Sheets.

Postretirement Benefits Other Than Pensions

The Company sponsors a postretirement ("OPEB") plan that provides for healthcare benefits, and in some instances, life insurance benefits, that cover certain eligible retired employees. The Company funds postretirement benefit obligations principally on a pay-as-you-go basis. Generally, postretirement health benefits are contributory with contributions adjusted annually. Life insurance plans for retirees are primarily noncontributory. Net periodic postretirement benefit income is included within Other (income) expense, net within the Consolidated Statements of Comprehensive Income.

The benefit obligation related to the Company's postretirement plans as of December 31, 2020 and 2019 was $5.2 million and $6.8 million, respectively, and is classified as Accrued compensation and benefits and Postemployment and other benefit liabilities within the Consolidated Balance Sheets. Net periodic postretirement benefit income was not material for any of the years ended December 31, 2020, 2019 or 2018, nor is it projected to be material for 2021. Benefit payments for postretirement benefits, which are net of expected plan participant contributions and Medicare Part D subsidies, are expected to be less than $1 million per year for the foreseeable future.

Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value measurements are based on a framework that utilizes the inputs market participants use to determine the fair value of an asset or liability and establishes a fair value hierarchy to prioritize those inputs. The fair value hierarchy is comprised of the three levels described below:

•Level 1 – Inputs based on quoted prices in active markets for identical assets or liabilities.

•Level 2 – Inputs other than Level 1 quoted prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

•Level 3 – Unobservable inputs based on little or no market activity and that are significant to the fair value of the assets and liabilities.

The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs are obtained from independent sources and can be validated by a third

party, whereas unobservable inputs reflect assumptions regarding what a third party would use in pricing an asset or liability based on the best information available under the circumstances. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

Assets and liabilities measured at fair value at December 31, 2020, were as follows:

	Fair value measurements						Total fair value

Total financial instruments not carried at fair value	$	—	$	1,474.0	$	—	$	1,474.0

The Company determines the fair value of its financial assets and liabilities using the following methodologies:

•Investments – These instruments include equity mutual funds and corporate bond funds. The fair value is obtained based on observable market prices quoted on public exchanges for similar instruments.

•Derivative instruments – These instruments include foreign currency contracts for non-functional currency balance sheet exposures, including both those that are and are not designated as cash flow hedges. As of December 31, 2019, these instruments also included interest rate swap contracts, which expired in September 2020, related to the Company’s variable rate Term Facility. The fair value of the foreign currency contracts is determined based on a pricing model that uses spot rates and forward prices from actively quoted currency markets that are readily accessible and observable. The fair value of the interest rate swap contracts was determined based on quoted prices for the Company’s swaps, which was not considered an active market.

•Deferred compensation and other retirement plans - These include obligations related to deferred compensation and other retirement plans adjusted for market performance. The fair value is obtained based on observable market prices quoted on public exchanges for similar instruments.

•Debt – These instruments are recorded at cost and include senior notes maturing through 2029. The fair value of the long-term debt instruments is obtained based on observable market prices quoted on public exchanges for similar instruments.

The carrying values of Cash and cash equivalents, Restricted cash, Accounts and notes receivable, net, Accounts payable, Accrued compensation and benefits and Accrued expenses and other current liabilities are a reasonable estimate of their fair value due to the short-term nature of these instruments. As discussed in Note 2, the Company also has investments in debt and equity securities without readily determinable fair values, which are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer and are qualitatively assessed for impairment indicators at each reporting period. As these investments are considered to be nonrecurring fair value measurements, they are not included in the fair value tables above.

The methodologies used by the Company to determine the fair value of its financial assets and liabilities at December 31, 2020, are the same as those used at December 31, 2019.

Share-based Payment Arrangement, Disclosure [Abstract]

Share-Based Compensation

SHARE-BASED COMPENSATION

The Company records share-based compensation awards using a fair value method and recognizes compensation expense for an amount equal to the fair value of the share-based payment issued in its financial statements. The Company’s share-based compensation plans include programs for stock options, restricted stock units ("RSUs"), performance stock units ("PSUs") and deferred compensation.

Under the Company's incentive stock plan, the total number of ordinary shares authorized by the shareholders is 8.0 million, of which 2.9 million remain available as of December 31, 2020 for future incentive awards.

Compensation Expense

Share-based compensation expense is included in Cost of goods sold and Selling and administrative expenses within the Consolidated Statements of Comprehensive Income. The following table summarizes the expenses recognized for the years ended December 31:

In millions	2020		2019		2018
Stock options	$	3.8	$	3.5	$	4.3
RSUs	11.4		10.0		9.6
PSUs	5.6		6.9		5.7
Deferred compensation	2.4		3.2		(0.8)
Pre-tax expense	23.2		23.6		18.8
Tax benefit(a)	(2.9)		(3.0)		(1.9)
After-tax expense	$	20.3	$	20.6	$	16.9

(a)Tax benefit reflected in the table above does not include the excess benefit from exercises and vesting of share-based compensation of $4.5 million, $2.8 million and $1.5 million for the years ended December 31, 2020, 2019 and 2018, respectively.

Stock Options / RSUs

Eligible participants may receive (i) stock options, (ii) RSUs or (iii) a combination of both stock options and RSUs. The fair value of each of the Company’s stock option and RSU awards is expensed on a straight-line basis over the required service period, which is generally the 3-year vesting period. However, for stock options and RSUs granted to retirement eligible employees, the Company recognizes expense for the fair value at the grant date.

The average fair value of the stock options granted for the years ended December 31, 2020, 2019 and 2018, was estimated to be $25.62, $19.58 and $21.29 per share, respectively, using the Black-Scholes option-pricing model. The weighted-average assumptions used were as follows:

	2020		2019		2018
Dividend yield	0.99	%	1.23	%	0.97	%
Volatility	20.70	%	21.44	%	22.38	%
Risk-free rate of return	1.41	%	2.53	%	2.75	%
Expected life	6.0 years		6.0 years		6.0 years

Volatility is based on the Company's historic volatility for the prior six years. The risk-free rate of return is based on the yield curve of a zero-coupon U.S. Treasury bond on the date the award is granted with a maturity equal to the expected term of the award. The expected life of the Company’s stock option awards is derived from the simplified approach based on the weighted-average time to vest and the remaining contractual term and represents the period of time that awards are expected to be outstanding.

Changes in options outstanding under the plans for the years ended December 31, 2020, 2019 and 2018, were as follows:

	Shares subject to option	Weighted- average exercise price(a)		Aggregate intrinsic value (millions)		Weighted-average remaining life (years)

At December 31, 2020, there was $1.5 million of total unrecognized compensation cost from stock option arrangements granted under the plan, which is primarily related to unvested shares of non-retirement eligible employees. The aggregate intrinsic value of the Company's options exercised during the years ended December 31, 2020 and 2019, was $18.8 million and $16.3 million, respectively. Generally, stock options expire ten years from their date of grant.

The following table summarizes RSU activity for the years ended December 31, 2020, 2019 and 2018:

(a)The weighted-average grant date fair value represents the fair value of the awards on the grant date converted to ordinary shares of the Company.

At December 31, 2020, there was $6.1 million of total unrecognized compensation cost from RSU arrangements granted under the plan, which is related to unvested shares of non-retirement eligible employees.

Performance Stock

The Company has a Performance Stock Program ("PSP") for key employees which provides awards in the form of PSUs based on performance against pre-established objectives. The annual target award level is expressed as a number of the Company's ordinary shares. All PSUs are settled in the form of ordinary shares unless deferred.

In February 2018, 2019 and 2020, the Company's Compensation Committee granted PSUs that were earned based 50% upon a performance condition, measured at each reporting period by earnings per share ("EPS") performance in relation to pre-established targets set by the Compensation Committee, and 50% upon a market condition, measured by the Company’s relative total shareholder return ("TSR") against the S&P 400 Capital Goods Index over a three-year performance period. The fair values of the market conditions are estimated using a Monte Carlo simulation approach in a risk-neutral framework to model future stock price movements based upon historical volatility, risk-free rates of return and correlation matrix.

The following table summarizes PSU activity for the maximum number of shares that may be issued for the years ended December 31, 2020, 2019 and 2018:

	PSUs	Weighted-average grant date fair value(a)
Outstanding and unvested at December 31, 2017	160,823	$	55.02

Forfeited	(2,647)	121.43
Outstanding and unvested at December 31, 2020	145,976	$	93.89

(a)The weighted-average grant date fair value represents the fair value of the awards on the grant date converted to ordinary shares of the Company.

At December 31, 2020, there was $4.6 million of total unrecognized compensation cost from the PSP based on current performance, which is related to unvested shares. This compensation will be recognized over the required service period, which is generally the three-year vesting period.

Deferred Compensation

Prior to 2019, the Company allowed key employees to defer a portion of their eligible granted PSUs and/or compensation into a number of investment choices including its ordinary share equivalents. Any amounts invested in ordinary share equivalents will be settled in ordinary shares of the Company at the time of distribution.

The Company also incurred other non-qualified restructuring charges of $1.2 million, $5.7 million and $1.6 million during the years ended December 31, 2020, 2019 and 2018, respectively, which represent costs directly attributable to restructuring activities, but that do not fall into the severance, exit or disposal category. Approximately $4.3 million of the non-qualified restructuring expenses incurred during 2019 related to the closure of the Company's production facility in Turkey. Non-qualified restructuring charges are included within Cost of goods sold and Selling and administrative expenses within the Consolidated Statements of Comprehensive Income.

The Company anticipates additional future restructuring charges of approximately $5 to $10 million related to certain of the restructuring actions initiated during the year ended December 31, 2020, primarily across several businesses and functions intended to optimize and simplify the Company's non-U.S. operations and cost structure. These future costs are expected to be cash expenditures and classified as both qualified and non-qualified restructuring. These costs are expected to be incurred within fiscal year 2021.

On December 22, 2017, the Tax Reform Act became law, resulting in broad and complex changes to the U.S. tax code. The impact to the Company's Consolidated Financial Statements during the year ended December 31, 2017, included, but were not limited to, a (1) reduced U.S. federal corporate tax rate from 35.0% to 21.0%, effective January 1, 2018, (2) required a one-time transition tax on certain unrepatriated earnings of non-U.S. subsidiaries and (3) required review of the future realizability of deferred tax balances.

Shortly after the Tax Reform Act was enacted, the SEC staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (SAB 118) which provided guidance on accounting for the Tax Reform Act’s impact. SAB 118 provided a measurement period, which in no case was to extend beyond one year from the Tax Reform Act enactment date, during which a company acting in good faith could complete the accounting for the impacts of the Tax Reform Act under ASC Topic 740. In finalizing the net tax charge resulting from the Tax Reform Act, in accordance with the one-year SAB 118 measurement period, the Company reversed $22.8 million of previous charges and recorded an additional $0.9 million of transition tax in 2018.

The majority of the Company's earnings are considered permanently reinvested, and therefore, the Company has not recorded any incremental withholding or income tax liabilities on earnings of its non-U.S. subsidiaries.

At December 31, a summary of the deferred tax accounts was as follows:

Gross deferred tax liabilities	(147.5)		(134.6)
Net deferred tax assets	$	58.1	$	43.3

At December 31, 2020, $1.4 million of deferred taxes were recorded for certain undistributed earnings of non-U.S. subsidiaries. Historically, no deferred taxes have been provided for any portion of the remaining undistributed earnings of the Company's subsidiaries since these earnings have been, and will continue to be, permanently reinvested in these subsidiaries. For many reasons, including the number of legal entities and jurisdictions involved, the complexity of the Company's legal entity structure, the complexity of tax laws in the relevant jurisdictions and the impact of projections of income for future years to any calculations, the Company believes it is not practicable to estimate, within any reasonable range, the amount of additional taxes which may be payable upon the distribution of earnings.

At December 31, 2020, the Company had the following tax losses and tax credit carryforwards available to offset taxable income in prior and future years:

In millions	Amount		Expiration Period
U.S. Federal tax loss carryforwards	$	18.9	2027-2037
U.S. Federal and State credit carryforwards	22.5		2025-2037
U.S. State tax loss carryforwards	22.9		2021-Unlimited
Non-U.S. tax loss carryforwards	$	1,015.8	2021-Unlimited

The U.S. state loss carryforwards were incurred in various jurisdictions. The non-U.S. loss carryforwards were incurred in various jurisdictions, predominantly in China, Ireland, Italy, Luxembourg and the United Kingdom.

The Company evaluates its deferred income tax assets to determine if valuation allowances are required or should be adjusted. GAAP requires that companies assess whether valuation allowances should be established against their deferred tax assets based on consideration of all available evidence, both positive and negative, using a "more likely than not" standard. This assessment considers the nature, frequency and amount of recent losses, the duration of statutory carryforward periods and tax planning strategies. In making such judgments, significant weight is given to evidence that can be objectively verified.

Activity associated with the Company’s valuation allowance is as follows:

In millions	2020		2019		2018
Beginning balance	$	241.0	$	357.1	$	312.9
Increase to valuation allowance	21.1		2.8		70.9
Decrease to valuation allowance	(2.8)		(118.6)		(25.0)
Foreign exchange translation	0.4		(0.3)		(1.7)
Ending balance	$	259.7	$	241.0	$	357.1

During the year ended December 31, 2020, the valuation allowance increased by $18.7 million, while during the year ended December 31, 2019, the valuation allowance decreased by $116.1 million. The increase for the year ended December 31, 2020, and the decrease for the year ended December 31, 2019, are the result of changes in country specific tax laws, internal restructurings, jurisdictional profitability and changes in judgments and facts regarding the realizability of deferred tax assets.

The Company has total unrecognized tax benefits of $41.2 million and $37.3 million as of December 31, 2020 and 2019, respectively. The amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is $41.2 million as of December 31, 2020. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

In millions	2020		2019		2018
Beginning balance	$	37.3	$	42.0	$	29.0
Additions based on tax positions related to the current year	6.0		5.7		9.5
Additions based on tax positions related to prior years	4.1		1.7		8.2
Reductions based on tax positions related to prior years	(1.5)		(7.0)		(1.4)
Reductions related to settlements with tax authorities	(0.3)		(4.0)		(1.5)
Reductions related to lapses of statute of limitations	(5.2)		(0.8)		(1.1)
Translation loss/(gain)	0.8		(0.3)		(0.7)
Ending balance	$	41.2	$	37.3	$	42.0

The Company records interest and penalties associated with the uncertain tax positions within its provision for income taxes. The Company had reserves associated with interest and penalties, net of tax, of $7.6 million and $6.2 million at December 31, 2020 and 2019, respectively. For the years ended December 31, 2020 and 2019, the Company recognized $1.9 million and $1.3 million in net interest and penalties, net of tax, related to these uncertain tax positions.

The total amount of unrecognized tax benefits relating to the Company's tax positions is subject to change based on future events including, but not limited to, the settlements of ongoing audits and/or the expiration of applicable statutes of limitations. Although the outcomes and timing of such events are highly uncertain, it is reasonably possible that the balance of gross unrecognized tax benefits, excluding interest and penalties, could potentially be reduced by up to approximately $14.8 million during the next 12 months.

The provision for income taxes involves a significant amount of management judgment regarding interpretation of relevant facts and laws in the jurisdictions in which the Company operates. Future changes in applicable laws, projected levels of taxable income and tax planning could change the effective tax rate and tax balances recorded by the Company. In addition, tax authorities periodically review income tax returns filed by the Company and can raise issues regarding its filing positions, timing and amount of income or deductions and the allocation of income among the jurisdictions in which the Company operates. A significant period of time may elapse between the filing of an income tax return and the ultimate resolution of an issue raised by a tax authority with respect to that return. In the normal course of business, the Company is subject to examination by taxing authorities throughout the world, including such major jurisdictions as Australia, Canada, France, Germany, Italy, Mexico, the Netherlands and the U.S. In general, the examination of the material tax returns of subsidiaries of the Company is complete for the years prior to 2003, with certain matters being resolved through appeals and litigation.

Earnings Per Share (EPS)

Earnings Per Share [Abstract]

Earnings Per Share (EPS)

EARNINGS PER SHARE (EPS)Basic EPS is calculated by dividing Net earnings attributable to Allegion plc by the weighted-average number of ordinary shares outstanding for the applicable period. Diluted EPS is calculated after adjusting the denominator of the basic EPS calculation for the effect of all potentially dilutive ordinary shares, which in the Company’s case, includes shares issuable under share-based compensation plans.

The following table summarizes the weighted-average number of ordinary shares outstanding for basic and diluted earnings per share calculations:

In millions	2020	2019	2018
Weighted-average number of basic shares	92.3	93.6	95.0
Shares issuable under share-based compensation plans	0.5	0.7	0.7
Weighted-average number of diluted shares	92.8	94.3	95.7

At December 31, 2020, 0.1 million stock options were excluded from the computation of weighted-average diluted shares outstanding because the effect of including these shares would have been anti-dilutive.

Net Revenues

Dec. 31, 2020

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer

NET REVENUES

Net revenues are recognized based on the satisfaction of performance obligations under the terms of a contract. A performance obligation is a promise in a contract to transfer control of a distinct product or to provide a service, or a bundle of products or services, to a customer. The Company has two principal revenue streams, tangible product sales and services. Approximately 99% of consolidated Net revenues involve contracts with a single performance obligation, the transfer of control of a product or bundle of products to a customer. Transfer of control typically occurs when goods are shipped from the Company's facilities or at other predetermined control transfer points (for instance, destination terms). Net revenues are measured as the amount of consideration expected to be received in exchange for transferring control of the products and takes into account variable consideration, such as sales incentive programs including discounts and volume rebates. The existence of these programs does not preclude revenue recognition but does require the Company's best estimate of the variable consideration to be made based on expected activity, as these items are reserved for as a deduction to Net revenues over time based on the Company's historical rates of providing these incentives and annual forecasted sales volumes. The Company also offers a standard warranty with most product sales and the value of such warranty is included in the contractual price. The corresponding cost of the warranty obligation is accrued as a liability (see Note 21).

The Company's remaining Net revenues involve services, including installation and consulting. Unlike the single performance obligation to ship a product or bundle of products, revenue recognition related to services revenues is delayed until the service based performance obligations are satisfied. In some instances, customer acceptance provisions are included in sales arrangements to give the buyer the ability to ensure the service meets any established criteria. In these instances, revenue recognition is deferred until the performance obligations are satisfied, which could include acceptance terms specified in the arrangement being fulfilled through customer acceptance or a demonstration that established criteria have been satisfied. During the years ended December 31, 2020 and 2019, no adjustments related to performance obligations satisfied in previous periods were recorded.

The Company applies the practical expedients allowed under ASC 606 to omit the disclosure of remaining performance obligations for contracts with an original expected duration of one year or less and for contracts where the Company has the right to invoice for performance completed to date. The transaction price is not adjusted for the effects of a significant financing component, as the time period between control transfer of goods and services is less than one year. Sales, value-added and other similar taxes collected by the Company are excluded from Net revenues. The Company has also elected to account for shipping and handling activities that occur after control of the related goods transfers as fulfillment activities instead of performance obligations. These activities are included in Cost of goods sold in the Consolidated Statements of Comprehensive Income. The Company’s payment terms are generally consistent with the industries in which its businesses operate.

The following table shows the Company's Net revenues related to both tangible product sales and services for the years ended December 31, 2020, 2019 and 2018, respectively, disaggregated by business segment. Net revenues are shown by tangible product sales and services, as contract terms, conditions and economic factors affecting the nature, amount, timing and uncertainty around revenue recognition and cash flows are substantially similar within each of the two principal revenue streams:

	2020
In millions	Americas		EMEA		Asia Pacific		Consolidated
Net revenues
Products	$	2,016.7	$	530.4	$	141.8	$	2,688.9

Services	—		22.1		4.3		26.4
Total Net revenues	$	1,988.6	$	589.9	$	153.2	$	2,731.7

As of December 31, 2020 and 2019, neither the contract assets related to the Company's right to consideration for work completed but not billed nor the contract liabilities associated with contract revenue were material. As a practical expedient, the Company recognizes incremental costs of obtaining a contract, if any, as an expense when incurred if the amortization period of the asset would have been one year or less. The Company does not have any costs to obtain or fulfill a contract that are capitalized under ASC 606.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

COMMITMENTS AND CONTINGENCIES

The Company is involved in various litigation, claims and administrative proceedings, including those related to environmental and product warranty matters. Amounts recorded for identified contingent liabilities are estimates, which are reviewed periodically and adjusted to reflect additional information when it becomes available. Subject to the uncertainties inherent in estimating future costs for contingent liabilities, except as expressly set forth in this note, management believes that any liability which may result from these legal matters would not have a material adverse effect on the financial condition, results of operations, liquidity or cash flows of the Company.

Environmental Matters

The Company is dedicated to an environmental program to reduce the utilization and generation of hazardous materials during the manufacturing process and to remediate identified environmental concerns. As to the latter, the Company is currently engaged in site investigations and remediation activities to address environmental cleanup from past operations at current and former production facilities. The Company regularly evaluates its remediation programs and considers alternative remediation methods that are in addition to, or in replacement of, those currently utilized by the Company based upon enhanced technology and regulatory changes. Changes to the Company's remediation programs may result in increased expenses and increased environmental reserves.

The Company is sometimes a party to environmental lawsuits and claims and has, from time to time, received notices of potential violations of environmental laws and regulations from the U.S. Environmental Protection Agency and similar state authorities. It has also been identified as a potentially responsible party ("PRP") for cleanup costs associated with off-site waste disposal at federal Superfund and state remediation sites. For all such sites, there are other PRPs and, in most instances, the Company’s involvement is minimal.

In estimating its liability, the Company has assumed it will not bear the entire cost of remediation of any site to the exclusion of other PRPs who may be jointly and severally liable. The ability of other PRPs to participate has been taken into account, based on the Company's understanding of the parties’ financial condition and probable contributions on a per site basis. Additional lawsuits and claims involving environmental matters are likely to arise from time to time in the future.

The Company incurred $7.1 million, $1.7 million and $2.4 million of expenses during the years ended December 31, 2020, 2019 and 2018, respectively, for environmental remediation at sites presently or formerly owned or leased by the Company. Environmental remediation costs are recorded in Costs of goods sold within the Consolidated Statements of Comprehensive Income.

As of December 31, 2020 and 2019, the Company has recorded reserves for environmental matters of $21.1 million and $19.3 million, respectively. The total reserve at December 31, 2020 and 2019, included $4.4 million and $4.2 million, respectively, related to remediation of sites previously disposed by the Company. Environmental reserves are classified as Accrued expenses and other current liabilities or Other noncurrent liabilities within the Consolidated Balance Sheets based on the timing of their expected future payment. The Company's total current environmental reserve at December 31, 2020 and 2019, was $6.1 million

and $6.2 million, respectively, and the remainder is classified as noncurrent. Given the evolving nature of environmental laws, regulations and technology, the ultimate cost of future compliance is uncertain.

Warranty Liability

Standard product warranty accruals are recorded at the time of sale and are estimated based upon product warranty terms and historical experience. The Company assesses the adequacy of its liabilities and will make adjustments as necessary based on known or anticipated warranty claims, or as new information becomes available.

The changes in the standard product warranty liability for the years ended December 31, were as follows:

In millions	2020		2019		2018
Balance at beginning of period	$	15.9	$	14.5	$	14.1
Reductions for payments	(7.3)		(8.4)		(7.9)
Accruals for warranties issued during the current period	8.2		10.3		7.8
Changes to accruals related to preexisting warranties	(0.6)		(0.4)		0.2
Acquisitions	—		—		0.5
Translation	0.3		(0.1)		(0.2)
Balance at end of period	$	16.5	$	15.9	$	14.5

Standard product warranty liabilities are classified as Accrued expenses and other current liabilities or Other noncurrent liabilities within the Consolidated Balance Sheets based on the timing of the expected future payments.

Segment Reporting [Abstract]

Business Segment Information

BUSINESS SEGMENT INFORMATION

The Company classifies its business into the following three reportable segments based on industry and market focus: Americas; Europe, Middle East and Africa ("EMEA"); and Asia Pacific. Results for the Company's India operations are now included within the Asia Pacific segment results due to an operational change during the year ended December 31, 2020. This change did not result, and is not expected to result, in a material impact to Segment results of operations for either the EMEA or Asia Pacific segment.

The Company largely evaluates performance based on Segment operating income and Segment operating margins. Segment operating income is the measure of profit and loss that the Company’s chief operating decision maker uses to evaluate the financial performance of the business and as the basis for resource allocation, performance reviews and compensation. For these reasons, the Company believes that Segment operating income represents the most relevant measure of segment profit and loss. The Company’s chief operating decision maker may exclude certain charges or gains, such as corporate charges and other special charges, from Operating income to arrive at a Segment operating income that is a more meaningful measure of profit and loss upon which to base operating decisions. The Company defines Segment operating margin as Segment operating income as a percentage of the segment's Net revenues.

A summary of operations and balance sheet information by reportable segments as of and for the years ended December 31 were as follows:

Summary of Significant Accounting Policies (Policy)

12 Months Ended

Dec. 31, 2020

Accounting Policies [Abstract]

Principles of Consolidation

Principles of Consolidation: The Consolidated Financial Statements include all controlled subsidiaries of the Company. A noncontrolling interest in a subsidiary is considered an ownership interest in a controlled subsidiary that is not attributable to the Company. The Company includes noncontrolling interests as a component of Total equity in the Consolidated Balance Sheets and the Net earnings attributable to noncontrolling interests are presented as an adjustment from Net earnings used to arrive at Net earnings attributable to Allegion plc in the Consolidated Statements of Comprehensive Income.

Equity method affiliates represent unconsolidated entities over which the Company demonstrates significant influence but does not have a controlling financial interest. The Company is also required to consolidate variable interest entities in which it bears a majority of the risk to the entity’s potential losses or stands to gain from a majority of the entity’s expected returns.

Use of Estimates

Use of Estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Estimates are based on several factors including the facts and circumstances available at the time the estimates are made, historical experience, risk of loss, general economic conditions and trends and the assessment of the probable future outcome. Some of the more significant estimates include useful lives of property, plant and equipment and intangible assets, purchase price allocations of acquired businesses, valuation of assets and liabilities including goodwill and other intangible assets, product warranties, sales allowances, pension plan benefits, postretirement benefits other than pensions, taxes, lease related assets and liabilities, environmental costs and product liability and other contingencies. Actual results could differ from those estimates. Estimates and assumptions are reviewed periodically, and the effects of changes, if any, are reflected in the Consolidated Statements of Comprehensive Income in the period they are determined.

Currency Translation

Currency Translation: Assets and liabilities where the functional currency is not the U.S. dollar have been translated at year-end exchange rates, and income and expense accounts have been translated using average exchange rates throughout the year. Adjustments resulting from the process of translating a subsidiary’s financial statements into the U.S. dollar are recorded to Accumulated other comprehensive loss.

Cash and Cash Equivalents

Cash and Cash Equivalents: Cash and cash equivalents include cash on hand, demand deposits and all highly liquid investments with original maturities at the time of purchase of three months or less.

Allowance for Doubtful Accounts

Allowance for Doubtful Accounts: The Company provides for an allowance for doubtful accounts and notes receivable, which represents the best estimate of expected lifetime credit losses inherent in the Company’s accounts and notes receivable portfolios. The Company's estimates are influenced by a continuing credit evaluation of customers' financial condition, trade accounts and notes receivable aging and historical loss experience, as well as reasonable and supportable forecasts of future economic conditions. The Company has reserved $6.2 million and $5.6 million for doubtful accounts and notes receivable as of December 31, 2020 and 2019, respectively.

Inventories

Inventories: Inventories are stated at the lower of cost and net realizable value using the first-in, first-out (FIFO) method.

Property, Plant and Equipment

Property, Plant and Equipment: Property, plant and equipment are stated at cost, less accumulated depreciation. Assets placed in service are recorded at cost and depreciated using the straight-line method over the estimated useful life of the asset except for leasehold improvements, which are depreciated over the shorter of their economic useful life or their lease term. Repair and maintenance costs that do not extend the useful life of the asset are expensed as incurred. Major replacements and significant improvements that increase asset values and extend useful lives are capitalized. The range of useful lives used to depreciate property, plant and equipment is as follows:

Buildings	10	to	50	years
Machinery and equipment	2	to	12	years
Software	2	to	7	years

The Company assesses the recoverability of the carrying value of its property, plant and equipment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be fully recoverable. Recoverability is measured by a comparison of the carrying amount of an asset to the future net undiscounted cash flows expected to be generated by the asset. If the undiscounted cash flows are less than the carrying amount of the asset, an impairment loss is recognized for the amount by which the carrying value of the asset exceeds its fair value.

Investments

Investments: The Company periodically invests in debt or equity securities of start-up companies and/or development stage technology or other companies without acquiring a controlling interest. The Company applies the equity method of accounting when the Company has the ability to exercise significant influence over the operating and financial decision making of the investee. Investments in equity method affiliates totaled $17.4 million and $18.2 million as of December 31, 2020 and 2019, respectively. Equity investments that have readily determinable fair values in which the Company does not have significant influence are measured at fair value, with any unrealized holding gains and losses being recorded to earnings. Investments without readily determinable fair values are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer and are qualitatively assessed for impairment indicators each reporting period. Investments in debt and equity securities not accounted for under the equity method of accounting totaled $13.7 million and $18.1 million as of December 31, 2020 and 2019, respectively. The Company's investments are principally recorded within Other noncurrent assets within the Consolidated Balance Sheets.

Leases

Leases: In accordance with ASC 842, the Company records a right-of-use ("ROU") asset and lease liability for substantially all leases for which it is a lessee. In determining if a contract represents a lease, consideration is given to all relevant facts and circumstances to assess whether or not the contract conveys the right to control the use of an identified asset, either explicit or implicit, for a period of time in exchange for consideration. Judgment and estimation is also required in determining the lease classification and the amount of the ROU asset and corresponding lease liability for each lease, which includes determining the appropriate lease term and an applicable discount rate. The Company assesses the specific terms and conditions of each lease to determine the appropriate classification as either an operating or finance lease. In determining the appropriate length of the lease term, both the minimum period over which lease payments are required plus any renewal options that are both within the Company's control to exercise and reasonably certain of being exercised as of lease commencement are considered. When available, the rate implicit in the lease is utilized as the discount rate to determine the lease liability. If this rate is unavailable, the Company utilizes its incremental borrowing rate as the discount rate, which is the rate at inception of the lease that would hypothetically be incurred to borrow over a similar term the funds needed to purchase the leased asset. Refer to Note 11 for further details on the Company's lease accounting policies.

Goodwill and Intangible Assets

Goodwill and Intangible Assets: The Company records as goodwill the excess of the purchase price of an acquired business over the fair value of the net assets acquired. Once the final valuation has been performed for each acquisition, adjustments may be recorded. In accordance with ASC 350, "Intangibles—Goodwill and Other", goodwill and other indefinite-lived intangible assets are tested and reviewed annually for impairment during the fourth quarter or whenever there is a significant change in events or circumstances that indicate the fair value of a reporting unit or indefinite-lived intangible asset is more likely than not less than the carrying amount of the asset.

Recoverability of goodwill is measured at the reporting unit level. The carrying amount of a reporting unit is compared to its estimated fair value. If the estimated fair value of a reporting unit exceeds it's carrying amount, goodwill of the reporting unit is not impaired. To the extent that the carrying value of the reporting unit exceeds its estimated fair value, a goodwill impairment charge will be recognized for the amount by which the carrying value of the reporting unit exceeds its fair value, not to exceed the carrying amount of the reporting unit's goodwill. Estimated fair value of the Company's reporting units is based on two valuation techniques, a discounted cash flow model (income approach) and a market multiple of earnings (market approach), with each method being weighted in the calculation.

As a result of the global economic disruption and uncertainty due to the novel coronavirus ("COVID-19") pandemic, the Company concluded a triggering event had occurred as of March 31, 2020, and accordingly, performed interim impairment tests on the goodwill balances of its EMEA and Asia Pacific reporting units. Given the high degree of market volatility and lack of reliable market data that existed as of March 31, 2020, the Company determined a discounted cash flow model (income approach) provided the best approximation of fair value of these reporting units for the purpose of performing these interim tests. This was a change in estimate, as historically the determination of reporting unit fair values has been estimated based on both an income and a market approach, as discussed above, with each method being weighted in the calculation. As markets stabilized throughout the year, the Company reverted to utilizing both an income and market approach while performing its annual impairment test in the fourth quarter.

Recoverability of other intangible assets with indefinite useful lives (i.e. Trade names) is determined on a relief from royalty methodology, which is based on the implied royalty paid, at an appropriate discount rate, to license the use of an asset rather than owning the asset. The present value of the after-tax cost savings (i.e. royalty relief) indicates the estimated fair value of the asset. Any excess of the carrying value over the estimated fair value is recognized as an impairment loss equal to that excess.

Intangible assets such as completed technologies, patents, customer-related intangible assets and other intangible assets with finite useful lives are amortized on a straight-line basis over their estimated economic lives. The weighted-average useful lives approximate the following:

Customer relationships	20	years
Trade names (finite-lived)	25	years
Completed technologies/patents	10	years
Other	7	years

Recoverability of intangible assets with finite useful lives is assessed in the same manner as property, plant and equipment, as described above.

Income Taxes

Income Taxes: The calculation of the Company’s income taxes involves considerable judgment and the use of both estimates and allocations. Deferred tax assets and liabilities are determined based on temporary differences between financial reporting and tax bases of assets and liabilities, applying enacted tax rates expected to be in effect for the year in which the differences are expected to reverse. The Company recognizes future tax benefits, such as net operating losses and tax credits, to the extent that realizing these benefits is considered in its judgment to be more likely than not. The Company regularly reviews the recoverability of its deferred tax assets considering its historic profitability, projected future taxable income, timing of the reversals of existing temporary differences and the feasibility of its tax planning strategies. Where appropriate, the Company records a valuation allowance with respect to future tax benefits.Cash paid for income taxes, net of refunds, for the twelve months ended December 31, 2020 and 2019 was $82.6 million and $103.0 million, respectively.

Product Warranties

Product Warranties: The Company offers a standard warranty with most product sales, and the value of such warranty is included in the contractual sales price. Standard product warranty accruals are recorded at the time of sale and are estimated based upon product warranty terms and historical experience. The Company regularly assesses the adequacy of its liabilities and makes adjustments as necessary based on known or anticipated warranty claims, or as new information becomes available. Refer to Note 21 for further details regarding product warranties.

Revenue Recognition

Revenue Recognition: Net revenues are recognized based on the satisfaction of performance obligations under the terms of a contract. A performance obligation is a promise in a contract to transfer control of a distinct product or to provide a service, or a bundle of products or services, to a customer. The Company has two principal revenue streams, tangible product sales and services. Approximately 99% of consolidated Net revenues involve contracts with a single performance obligation, the transfer of control of a product or bundle of products to a customer. The Company's remaining Net revenues involve services, including installation and consulting. See Note 20 for additional information regarding the Company's revenue recognition policies.

Sales returns and customer disputes involving a question of quantity or price are accounted for as variable consideration, and therefore, as a reduction to Net revenues and as a contra receivable. At December 31, 2020 and 2019, the Company had a customer claim accrual (contra receivable) of $48.6 million and $36.5 million, respectively. All other incentives or incentive programs where the customer is required to reach a certain level of purchases, remain a customer for a certain period, provide a rebate form or is subject to additional requirements are also considered variable consideration and are accounted for as a reduction of revenue and a liability. At December 31, 2020 and 2019, the Company had a sales incentive accrual of $35.0 million and $37.2 million, respectively. Variable consideration is estimated based on the most likely amount expected to be

received from customers. Each of these accruals represents the Company’s best estimate of the most likely amount expected to be received from customers based on historical experience. These estimates are reviewed regularly for accuracy, and if updated information or actual amounts are different from previous estimates, the revisions are included in the Company’s results for the period in which they become known. Historically, the aggregate differences, if any, between the Company’s estimates and actual amounts in any year have not had a material impact on the Consolidated Financial Statements. The Company also offers a standard warranty with most product sales, and the value of such warranty is included in the contractual price. The corresponding cost of the warranty obligation is accrued as a liability.

Environmental Costs

Environmental Costs: The Company is subject to laws and regulations relating to protecting the environment. Environmental expenditures relating to current operations are expensed or capitalized as appropriate. Expenditures relating to existing conditions caused by past operations, which do not contribute to current or future revenues, are expensed. Liabilities for remediation costs are recorded when they are probable and can be reasonably estimated, generally no later than the completion of feasibility studies or the Company’s commitment to a plan of action. The assessment of this liability, which is calculated based on existing technology, does not reflect any offset for possible recoveries from insurance companies and is not discounted. Refer to Note 21 for further details related to environmental matters.

Research and Development Costs

Research and Development Costs: The Company conducts research and development activities for the purpose of developing and improving new products and services. These costs are expensed when incurred. For the years ended December 31, 2020, 2019 and 2018, expenses related to research and development activities amounted to approximately $54.4 million, $54.7 million and $54.4 million, respectively, and primarily consist of salaries, wages, benefits, facility costs and other overhead expenses.

Employee Benefit Plans

Defined Benefit Plans: The Company provides a range of defined benefits, including pension, postretirement and postemployment benefits to eligible current and former employees. Determining the costs associated with such benefits is dependent on various actuarial assumptions, including discount rates, expected return on plan assets, compensation increases, employee mortality and turnover rates. Actuaries perform the required calculations to determine expense in accordance with GAAP. Actual results may differ from the actuarial estimates and are generally recorded to Accumulated other comprehensive loss and amortized into Net earnings over future periods. The Company reviews its actuarial assumptions at each measurement date and makes modifications to the assumptions as appropriate. Refer to Note 12 for further details on employee benefit plans.

Loss Contingencies

Loss Contingencies: Liabilities are recorded for various contingencies arising in the normal course of business, including litigation and administrative proceedings, environmental matters, product liabilities, product warranties, worker’s compensation and other claims. The Company has recorded reserves in the financial statements related to these matters, which are developed using inputs derived from actuarial estimates and historical and anticipated experience data depending on the nature of the reserve and, in certain instances, with consultation of legal counsel, internal and external consultants and engineers. Subject to the uncertainties inherent in estimating future costs for these types of liabilities, the Company believes its estimated reserves are reasonable and does not believe the final determination of the liabilities with respect to these matters would have a material effect on the financial condition, results of operations, liquidity or cash flows of the Company for any year. Refer to Note 21 for further details related to loss contingencies.

Derivative Instruments

Derivative Instruments: The Company periodically enters into cash flow and other derivative transactions to specifically hedge exposure to various risks related to currency and variable interest rates. The Company recognizes all derivatives on the Consolidated Balance Sheets at their fair value as either assets or liabilities. For designated cash flow hedges, the changes in fair value of the derivative contract is recorded to Accumulated other comprehensive loss and reclassified into Net earnings at the time earnings are affected by the hedged transaction. For undesignated derivative transactions, the changes in the fair value of the derivative contract are immediately recognized in Net earnings. Refer to Note 10 for further details regarding derivative instruments.

New Accounting Pronouncements

Recently Adopted Accounting Pronouncements:

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." The new guidance within ASU 2016-13, along with related updates (collectively "ASC 326") introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. The new guidance became effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods. Accordingly, the Company adopted ASC 326 on January 1, 2020, using the modified retrospective transition method through a $2.2 million cumulative-effect decrease to retained earnings. The Company has also made updates to its policies and internal controls over financial reporting as a result of adoption.

In August 2018, the FASB issued ASU 2018-15, "Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." The new guidance aligns the requirements for capitalizing implementation costs incurred in a cloud-based hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 became effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods. Accordingly, the Company adopted ASU 2018-15 on January 1, 2020, using the prospective method of adoption, and the adoption did not have a material impact to the Consolidated Financial Statements.

Recently Issued Accounting Pronouncements:

In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." The new guidance is intended to simplify the accounting for income taxes by removing certain exceptions and by updating accounting requirements around franchise taxes, goodwill recognized for tax purposes, the allocation of current and deferred tax expense among legal entities, among other minor changes. The ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted. The Company adopted ASU 2019-12 on January 1, 2021, and the adoption did not have a material impact to the Consolidated Financial Statements.

In January 2020, the FASB issued ASU 2020-01, "Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815." The amendments in ASU 2020-01 clarify the interaction of the accounting for equity securities under Topic 321 and investments accounted for under the equity method of accounting. The ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted. The Company adopted ASU 2020-01 on January 1, 2021, and the adoption did not have a material impact to the Consolidated Financial Statements.

In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." This ASU, along with related updates, provides temporary optional expedients and exceptions for applying GAAP to contract modifications, hedging relationships and other transactions if certain criteria are met in order to ease the potential accounting and financial reporting burden associated with the expected market transition away from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. The ASU is currently effective and may be applied prospectively at any point through December 31, 2022 at the Company’s option. The Company is assessing what impact ASU 2020-04 will have on the Consolidated Financial Statements.
