•First, consumers are prioritizing wellbeing – their own and that of their families, and they understand the strong link between sleep and overall health and wellness;
•Second, consumers are adopting digital products and services at a much faster and higher rate, and they are increasingly relying on digital health solutions; and
•Third, consumers have a heightened preference for brands that are characterized by authentic purpose and human empathy.
Each of these shifts is enduring, fueling permanent changes in consumer purchasing behavior and propelling our profitable growth.
With our strategic, enterprise-wide investments in innovation, technology, logistics, marketing and customer service, we have created a competitively advantaged strategy and a highly relevant brand – which together, are delivering superior shareholder value.
Proprietary Sleep Innovations
Sleep Number 360 smart beds effortlessly deliver proven quality sleep by allowing each sleeper to set their ideal firmness, support and pressure-relieving comfort – their Sleep Number® setting. SleepIQ technology optimizes the smart benefits of the bed, continually improving a sleeper’s restful time asleep – their SleepIQ® score – to deliver a life-changing difference to their overall health and wellness.
Every night, through our proprietary SleepIQ technology, we collect more than 19 billion data points from our real-world sleepers, generating comprehensive and longitudinal data at a scale never seen before in sleep science. To date, we have leveraged and learned from nine billion hours of sleep data gathered from more than one billion sleep sessions. We are using our proprietary longitudinal data and artificial intelligence capabilities to advance smart bed hardware and bio-signal features, enabling us to provide connected sleep solutions that deliver ongoing impact for consumers’ wellbeing. We are creating and introducing solutions and technology that will meaningfully impact sleep for a healthier society. In the future, our award-winning 360® smart beds could provide a form of preventative and proactive health care that one day may detect or prevent serious health conditions like sleep apnea, restless leg syndrome and heart disease.
Based on analysis of more than 25 million sleep sessions, Sleep Number research shows that sleepers who routinely use their 360 smart bed features and SleepIQ technology can improve quality sleep by over 15 minutes each night, nearly 100 hours each year. Third-party studies have shown that even 15 more minutes of quality sleep per night increase a body’s ability to stave off weight gain or a cold, and can increase productivity.
In 2020, we unveiled the next generation of 360 smart beds with technology to advance our health and wellness platform and made several new sleep innovations available through our SleepIQ technology platform, including:
3

•Nighttime Heart Rate Variability (HRV) – a measure of the variation of time between each heartbeat, which can be an indication of an individual’s overall health. A high HRV, for example, may indicate greater cardiovascular fitness and physical recovery ability. With a consistent nighttime HRV snapshot – free from the influence of daytime external factors – 360 smart bed sleepers may better understand their resilience, activity level and energy each day;
•Sleep Circadian Insights – automatically tracks sleep and wake times for each sleeper in the SleepIQ® platform application. Using artificial intelligence, SleepIQ technology learns a sleeper’s patterns and provides guidance to optimize sleep and wake times, such as what time of day they are most alert or their optimal times to work out and go to bed. Analysis shows that sleepers who engage with the new feature experience a 35-minute improvement to sleep timing (i.e., more consistent bedtime and wake time) and a 2-point improvement to their SleepIQ score; and
•Monthly Sleep Wellness Reports – provides an overview of personalized insights, highlighting sleep health, circadian stability and respiratory and cardiovascular health via HRV. The report helps sleepers effortlessly understand their sleep and see how their sleep health has changed over time. Initial research indicated that 8 out of 10 users found the Sleep Wellness Reports to be valuable, and 40 percent of those users changed sleep-related behaviors based upon information provided in the reports, such as going to bed earlier or changing their pre-bedtime routine. Sleep Number 360 smart bed sleepers can share their Sleep Wellness Reports with their healthcare providers, giving physicians unique access to individualized data that could help provide a more holistic picture of patient health.
In 2020, we also announced our forthcoming Sleep Number Climate360™ smart bed, the first-ever bed that uses advanced temperature technology to create a personalized, responsive microclimate with automatic firmness adjustability. Unveiled at CES 2020, both the Climate360 and new 360 smart beds won prestigious awards, including the CES 2020 “Best of Innovation” award.
Sleep Number also offers a full line of exclusive FlexFit™ smart adjustable bases that allow customers to raise the head or foot of the bed. These industry leading FlexFit bases seamlessly integrate with SleepIQ technology to deliver features like our Partner Snore™ technology, which allows a sleeping partner to temporarily relieve mild snoring by raising their companion’s head at the touch of a button.
The SleepIQ Kids® k2 bed extends Sleep Number’s DualAir™ adjustability and SleepIQ technology to the children’s mattress market. The k2 bed adjusts with children as they grow, giving them the best possible sleep.
Our exclusive Sleep Number® bedding collection features a full line of sleep products designed to improve sleep comfort and quality, including a broad assortment of pillow sizes and shapes that fit each individual’s preferred sleeping position.
We also offer a variety of temperature-balancing products including the DualTemp™ layer. This proprietary sleep innovation features active air technology that allows each sleeper to select their ideal temperature at the simple touch of a button and can be used with any mattress brand or adjustable base.
Research and Sleep Science
Research and sleep science are at the core of all Sleep Number innovations. With global R&D operations in the USA, Europe and Asia, we conduct extensive research to understand consumers’ needs and inspire the design and delivery of our award-winning sleep innovations, our proprietary SleepIQ technology platform and our customer experience.
Our Minneapolis, MN-based R&D team leads the innovation of our smart mattress, adjustable base design, and bedding solutions and is comprised of experts in mechanical engineering, comfort, adjustability, temperature, anthropometrics and test systems. Our Sleep Number Labs team in San Jose, CA supports the evolution of SleepIQ technology with leading experts in sleep research, data science, analytics and full-stack Internet of Things platform development.
We have accelerated our investments in R&D to enhance our competitive advantage. We continue to enhance our expertise and capabilities specific to the healthcare industry, forming an internal SleepIQ health team, advancing Sleep Number’s leadership in connected sleep health and further underscoring the commitment to innovation in health and wellness. As a result of our R&D and strategic efforts, we have continued to grow our patent portfolio, with a particular focus on smart features that improve sleep quality, and thermal solutions to solve temperature disruptions to sleep. Our world-wide patent portfolio now contains more than 350 patents, which enhances our protection of our exclusive and proprietary technologies. Our research and development expenses were $41 million in 2020, $35 million in 2019 and $29 million in 2018.

Aligned with our purpose of improving the health and wellbeing of society, our scientific foundation is continually expanding as we engage with health care providers, researchers and consumers:
•Extending upon our collaboration with the world-renowned Mayo Clinic, Sleep Number is funding a research with Mayo Clinic to understand sleep’s impact on health and wellbeing. Together, we hope to amplify our impact on improving society’s overall sleep and wellness and improving patient outcomes. By uniting our sleep knowledge and technology with world-class clinicians and researchers, we aim to make meaningful advancements to the science of sleep, with goals to materially foster better sleep and health for society;
•To support our research endeavors, we founded the Sleep Number Scientific Advisory Board, an interdisciplinary group of physicians, clinicians and researchers with expertise in sleep science and health. Our leadership team works with this collective of internationally-known experts to gather counsel on the latest sleep science and research programs and to leverage their knowledge to innovate new sleep-health solutions; and
•In 2020, we also established several important research and development projects aimed at identifying underlying physiological warning signs of health issues. The new Sleep Science Research capability within the SleepIQ technology platform provides the Company’s smart sleeper community (our “Insiders” – customers and SleepIQ technology users) the opportunity to help advance sleep science with real-world data to understand sleep behaviors and outcomes. By opting in through the SleepIQ® app, 360 smart bed sleepers answer periodic surveys about their health. This self-reported health history is analyzed alongside anonymized and aggregated sleep and biometric data, allowing us to gain additional insights on sleep’s impact on holistic health. It may also inform the development of new products, services and partnerships to advance the science of sleep and possibly even predict future health trends.
This collaboration of our integrated, experienced team, our external partners and our expert advisors will advance sleep research and science, and enable consumers to proactively and comprehensively improve their sleep health through superior sleep solutions.
Exclusive Direct-to-Consumer Distribution
At a time when people are recognizing the importance of sleep to their overall health and wellbeing, Sleep Number is hyper-relevant in consumers’ lives. Not only are we a leader in sleep innovation, we are linking sleep to wellness and creating a future where people live happier, healthier and more productive lives.
Our exclusive, direct-to-consumer distribution model builds lifelong relationships with our customers. We employ technology across our customer touchpoints to deliver a value-added retail experience that integrates our digital and physical touchpoints to meet customer needs, and our mission-driven, highly-trained sleep experts use our best-in-class relationship-based selling process, which is continually tested and refined, to deliver high conversions. We offer an engaging and dynamic online experience, which was heavily optimized in 2020, to educate consumers and advance their purchase path, driving highly-qualified traffic to all our retail touchpoints: Stores, Online, Phone and Chat.
As the exclusive distributor of Sleep Number® products, we target high-quality, convenient and visible store locations based on several factors, including each market’s overall sales potential and store geography, demographics and proximity to other brand experiences. Since 2010, we have invested in repositioning a large percentage of our mall stores to stronger, optimally sized, non-mall locations, adding stores in both existing and new markets. As of January 2, 2021, we operated 602 Sleep Number® stores, with locations in all 50 states. More than 42% of our stores (including remodels) are less than five years old and more than 56% are less than seven years old.
In 2020, our direct-to-consumer model and synergies from our vertical integration as the exclusive designer, manufacturer, marketer, retailer and servicer of Sleep Number® beds enabled us to deliver a better, faster, simpler, safer and more engaging experience for our customers and our team members. In early fiscal April, with forced temporary closures of more than 80% of our stores and sales declining by almost 80% versus the prior year due to the COVID-19 pandemic, we reinvented our integrated operational processes through fast “test, learn, and apply” exercises, quickly advancing technology and digital capabilities and reskilling frontline teams. We rolled out a “sell-from-anywhere” model, an agile go-to-market approach that leveraged our sleep professionals’ skills in building customer relationships and aligned seamlessly with our customers’ shopping preferences: in-store, online or by phone. These actions drove efficient new customer acquisition, strong average revenue per unit, growth in number of new customers, bed units and increased conversion, producing a sharp recovery in Sleep Number’s sales and profitability.
Our Stores accounted for 85% of net sales in 2020. Average annual net sales per store, based on Total Retail (which includes Stores, Online, Phone and Chat), were $3.1 million in 2020, a new record. In 2020, 67% of our Stores open for a full year generated net sales of greater than $2 million, and 29% of our Stores open for a full year generated more than $3 million in net sales. In 2020, our Online, Phone and Chat sales accounted for 15% of our net sales, representing 108% year-over-year growth.

Brand Communications
Relevant, engaging and individualized communications have helped Sleep Number to become a beloved brand built on a foundation of individuality and wellbeing. Our deep understanding of, and insights about, our target customers, including structural shifts in consumer behavior that we have anticipated since the inception of our consumer innovation strategy in 2012 – and which were accelerated by the global pandemic – have guided our brand marketing strategies. To drive both new customer acquisition and retention (Insiders) business, our brand communications strategies are designed to emotionally connect consumers with high-quality content about the benefits of life-changing sleep and the value of our 360 smart bed: (i) we amplify our brand through strategic partnerships; (ii) we engage consumers seamlessly across multiple touchpoints with an emphasis on digital; and (iii) we create lifelong customer relationships and brand advocacy by delivering an unparalleled sleep experience. Together, these actions result in strong brand health, heightened consumer consideration and engagement, high-quality traffic, and authentic advocacy for Sleep Number’s brand, products and services.
Strategic partnerships amplify the effectiveness, impact and scale of our brand and marketing efforts:
•We are in the third year of our strategic partnership as the Official Sleep and Wellness Partner of the National Football League (NFL) – one of the world’s largest marketing and fan-engagement platforms. Our partnership with the NFL broadens our brand reach, deepens our brand relevance and magnifies the benefits of our proprietary innovations. Most active NFL players now have a Sleep Number 360 smart bed, which helps them compete more effectively by measuring, understanding and maximizing the benefits of a great night’s sleep; and
•Our multi-year partnerships with content platform organizations like Thrive Global and Katie Couric Media also provide opportunities to influence and educate consumers about the benefits of proven quality sleep on a regular basis.
We leverage a sophisticated media mix to drive our performance-marketing and advertising communications on a local and national scale, contributing to improved media return on investment (ROI). High-profile video, including television and online streaming, is our most efficient media, followed by digital and social platforms. Our world-class, in-house digital capabilities, content marketing, online user experience and data-driven tools give us the flexibility to pivot quickly and optimize media investment, messages and audience by platform in real-time. Our promotional strategy focuses on simplicity and relevance, driving consumers to the brand at the exact time they are seeking a smart bed. In 2020, media expense represented 13.6% of net sales.
We leaned into customer acquisition in 2019 and rapidly accelerated our digital capabilities in early 2020. We strengthened our digital engagement by delivering a superior personalized customer connection with our highly-knowledgeable sleep professionals. A new platform featuring modern, cloud-based architecture accelerated our “sell-from-anywhere” capability that makes it easy for our customers to get the exact Sleep Number solution they are looking for, on their own terms. By the third quarter of 2020, our digital traffic had surpassed all of 2019 and we delivered 80 basis points of leverage in our media spending in that quarter. Overall, 2020 represented our third straight year of double-digit, digital-traffic growth.
We focus on building lifelong relationships with our Insiders. The more deeply engaged our Insiders are with the brand, the greater their advocacy. Our smart sleeper community, now 1.6 million strong, interacts with our brand every day through SleepIQ technology. Our award-winning InnerCircle SM Rewards program amplifies this engagement and drives acquisition of new customers through referral, and greater retention with repeat purchases. We expect brand loyalty to accelerate as we roll out new health and wellness features in SleepIQ technology that will continue to benefit our Insiders’ lives. Insider referral and repeat sales represent greater than 45% of our business and are the most efficient source of new customers to the brand.
Operations
Integrated Sourcing and Logistics
Sleep Number’s integrated supply chain is a competitive advantage. Our commitments to innovation and continuous improvement are employed to leverage our vertical-business model by optimizing culture, processes and technology. In addition to a network of global suppliers, we currently operate two component manufacturing plants (Irmo, SC and Salt Lake City, UT) and four assembly distribution centers (Irmo, SC; Salt Lake City, UT; Ontario, CA; and Baltimore, MD) with two additional locations (Dallas, TX and Tampa, FL) opening in early 2021. Primary operations at the manufacturing sites include cutting and sewing of the fabric covers for our beds and final assembly and packaging of mattresses and bases. We also assemble our electrical Firmness Control™ systems in our Utah plant. Our plants have consistently won awards for safety and manufacturing excellence. We also operate a national bedding fulfillment center in Minneapolis, MN.
6

We source the raw materials and components used in our products from third parties. Various components are sourced from suppliers who currently serve as our sole or primary source of supply. We believe we can obtain these raw materials and components from other sources of supply, although we could experience short-term disruption in order fulfillment in the event of an unexpected loss of supply. We have taken, and continue to take, various measures to mitigate the potential impact of an unexpected supply disruption from any sole-source or primary suppliers, including maintaining safety stocks and identifying potential alternate suppliers. Our key suppliers have in place either contingency or disaster recovery plans or redundant production capabilities to minimize any unforeseen disasters.
At the end of 2020, approximately 50% of our smart beds were pre-assembled for delivery to customers’ homes while the remaining deliveries were assembled in customers’ homes. We are pursuing a multi-year evolution of our supply chain to pre-assemble 100% of our beds in as many as eight planned assembly distribution centers around the U.S. by 2022. We are advancing our outbound logistics network to reduce product handling, hand-offs, damage and costs while in transit to customers’ homes. We see these initiatives providing a superior and reliable experience for customers with lower costs for the business.
Home Delivery Service
Our home delivery teams are another direct touchpoint with our customers. Since 2018, 100% of our 360 smart beds sold are delivered and installed by our home delivery technicians or by our third-party service providers.
Our home delivery teams across the nation embraced the challenges of the COVID-19 pandemic in 2020, adopting measures to safeguard customer and team member health, while ensuring that customers were still able to receive the quality sleep they needed.
Customer Service
Through our U.S.-based, in-house customer service team located in Minneapolis, MN and New Orleans, LA, we provide direct post-purchase support that improves the customer experience and drives our business. Through frequent service and support interactions with customers via phone, email, live chat and social media, these team members also provide a unique opportunity to gather insights that help us continuously improve our products, strengthen our service quality and advance our innovation. This integration enables operational synergies and drives organizational efficiencies.
Throughout the pandemic, serving our customers remained our focus. In order to keep our team members safe, yet continue to provide a superior customer experience, our customer service teams in Minneapolis and New Orleans were provided with the technology tools and training to work from home.
Information Systems
We use information technology systems to operate, analyze and manage our business, to reduce operating costs and to enhance our customers’ experience. Our major systems include an in-store order entry system, a retail portal system, a payment processing system, in-bound and out-bound telecommunications systems for direct marketing, delivery scheduling and customer service, e-commerce systems, a data warehouse system and an enterprise resource planning (ERP) system. These systems are primarily comprised of packaged applications licensed from various software vendors plus a limited number of internally developed programs.
Intellectual Property
We hold various U.S. and foreign patents and patent applications regarding certain elements of the design and function of our products, including air control systems, remote control systems, air chamber features, mattress construction, foundation systems, sensing systems, automated adjustments, in-bed temperature control, as well as other technology. We have numerous U.S. patents, expiring at various dates between July 2021 and April 2039, and numerous U.S. patent applications pending. We also have numerous foreign patents and patent applications pending. Notwithstanding these patents and patent applications, we cannot ensure that these patent rights will provide substantial protection or that others will not be able to develop products that are similar to, or competitive with, our products.
We have a number of trademarks and service marks registered with the U.S. Patent and Trademark Office, including Sleep Number®, SleepIQ®, Sleep Number 360®, 360®, SleepIQ Kids®, the Double Arrow logo, Select Comfort®, AirFit®, BAM Labs®, the “B” logo, Comfortaire®, ComfortFit®, Comfort.Individualized.®, Does Your Bed Do That?®, the DualTemp logo, the DualAir Technology Inside logo, FlexTop®, IndividualFit®, It®, Know Better Sleep®, Pillow[ology]®, PillowFit®, Probably the Best Bed in the World®, Responsive Air®, Sleep Is Training®, Sleep Number Inner Circle®, Sleep30®, Smart Bed For Smart Kids®, Tech-e®, The Only Bed

We protect and enforce our intellectual property rights, including through litigation as necessary.
Industry and Competition
Sleep disorders have been declared a public health epidemic by the U.S. Center for Disease Control. One in three adults suffer from a lack of adequate sleep. Sleep Number is focused on producing products to address this growing problem. The total U.S. sleep-health economy was estimated to be $30 billion to $40 billion in a 2017 report published by McKinsey & Company. This reflects the traditional view of the bedding industry which includes the sales of mattresses and foundations, as well as emerging solutions for insufficient sleep such as routine modification and therapeutic treatment. We believe the sleep economy will continue to evolve and grow as consumers look for products and reliable data sources to address sleep deprivation challenges.
The traditional view of the U.S. bedding industry, including mattresses and foundations (static and adjustable), is measured through data provided by the International Sleep Products Association (ISPA). According to ISPA, the industry has grown by approximately 4% annually over the last 20 years, including 4% annually, on average, over the past five years. According to ISPA and our estimates, industry wholesale shipments of mattresses and foundations (including imported products and adjustable bases) were approximately $10.9 billion in 2020 (approximately $22 billion at retail).
The retail bedding industry is commoditized and highly competitive. Sleep Number competes against regional and local specialty bedding retailers, home furnishing stores, mass merchants, national discount stores and online marketers. Furniture/Today, a furniture industry trade publication, has ranked Sleep Number as the 5th largest mattress manufacturer and 2nd largest U.S. bedding retailer for 2019, with an estimated 8% market share of industry retail revenue. Our consumer innovation strategy with proprietary sleep innovations and exclusive direct-to-consumer distribution is highly differentiated, resulting in lifelong customer relationships and contributing to our continued profitable growth.
Manufacturers in the bedding industry compete through retail partners on price, quality, brand name recognition, product availability and product performance, including the perceived levels of comfort and support provided by a mattress. There is a high degree of concentration among manufacturers, who produce innerspring, memory foam and hybrid beds, under nationally recognized brand names, including Tempur Sealy, Stearns & Foster, Serta and Simmons. In recent years, numerous direct-to-consumer companies and low-cost importers have entered the market, offering “bed-in-a-box” products to consumers, primarily through online distribution though many now partner with traditional mattress retailers. Their products are generally foam-based and undifferentiated in terms of sleep benefits.
Governmental Regulation and Compliance
As a vertically integrated manufacturer and retailer, we are subject to extensive federal, state and local laws and regulations affecting all aspects of our business.
As a manufacturer, we are committed to product quality and safety, including adherence to all applicable laws and regulations affecting our products and services. Compliance with health, safety and environmental laws and regulations, including the federal fire retardant standards developed by the U.S. Consumer Product Safety Commission, which requires rigorous and costly testing, has increased the cost and complexity of manufacturing our products and may adversely impact the speed and cost of product development efforts. Further, our manufacturing, distribution, delivery and other business operations and facilities are subject to additional federal, state or local laws or regulations including supply chain transparency, conflict minerals sourcing and disclosure, end-of-life disposal and recycling requirements, transportation and other laws or regulations relating to environmental protection and health and safety requirements, including COVID-19 safety and prevention.
8

As a retailer, we are subject to additional laws and regulations that apply to retailers generally and govern the marketing and sale of our products and the operation of both our retail stores and our e-commerce activities. Many of the statutory and regulatory requirements that impact our retail and e-commerce operations are consumer-focused and pertain to activities such as our promotions, advertising claims, pricing, credit-based promotional offers, truth-in-advertising, privacy, “do not call/mail” requirements, text messaging requirements, warranty disclosure, delivery timing requirements, accessibility and similar requirements.
Our operations are subject to federal, state and local labor laws including, but not limited to, those relating to occupational health and safety, employee privacy, wage and hour, overtime pay, harassment and discrimination, equal opportunity and employee leaves and benefits. We are also subject to existing and emerging federal and state laws relating to data security and privacy.
It is our policy and practice to comply with all legal and regulatory requirements and our procedures and internal controls are designed to promote such compliance.
Seasonality
Our business is modestly impacted by seasonal influences inherent in the U.S. bedding industry and general retail shopping patterns. The U.S. bedding industry generally experiences lower sales in the second quarter of the calendar year and increased sales during selected holiday or promotional periods.
Working Capital
We are able to operate with minimal working capital requirements because we sell directly to customers, utilize a primarily hybrid “make-to-stock” production process and operate retail stores that serve mainly as showrooms. We have historically generated sufficient cash flows to self-fund operations through an accelerated cash-conversion cycle. Our Credit Agreement provides a revolving credit facility for general corporate purposes with net aggregate availability of $450 million. The Credit Agreement contains an accordion feature that allows us to increase the amount of the credit facility from $450 million up to $600 million in total availability, subject to Lenders’ approval. The Credit Agreement matures in February 2024.
Qualified customers are offered revolving credit to finance purchases through a private-label consumer credit facility provided by Synchrony Bank. Approximately 52% of our net sales in 2020 were financed by Synchrony Bank. Our current agreement with Synchrony Bank expires December 31, 2023, subject to earlier termination upon certain events. We pay Synchrony Bank a fee for extended credit promotional financing offers. Under the terms of our agreement, Synchrony Bank sets the minimum acceptable credit ratings, interest rates, fees and all other terms and conditions of the customers’ accounts, including collection policies and procedures. As the receivables are owned by Synchrony Bank, at no time are the receivables purchased or acquired from us. We are not liable to Synchrony Bank for our customers’ credit defaults. In connection with all purchases financed under these arrangements, Synchrony Bank pays us an amount equal to the total amount of such purchases, net of promotional related discounts, upon delivery to the customer. Customers that do not qualify for credit under our agreement with Synchrony Bank may apply for credit under a secondary program that we offer through another provider.
Human Capital
Our Team Members
Individuality is our foundation. Our Company was founded under the name Select Comfort in 1987 (public company since 1998), on the premise that “one size doesn’t fit all.” We celebrate individuality in each other, in our own lives and in our customer’s lives. We strive to embrace every individual’s unique talents, perspectives and experiences, as we create an environment where we can be our best selves. Valuing diversity, equity and inclusion makes us stronger, smarter and fuels our innovation and teamwork. Individuality connects us to our vision of becoming one of the world’s most beloved brands by delivering an unparalleled sleep experience.
Throughout 2020, our purpose sustained us, inspired us and informed our business decisions and actions, including gifting a smart bed to all of our team members, partnering with Make-A-Wish to support critically ill children with life changing sleep and joining the United Nations Global Compact. At January 2, 2021, we employed a total of 4,679 team members, of which 108 were employed on a part-time or temporary basis. The breakdown of team members by area was as follows: 2,250 in retail sales and support, 833 in field services, 408 in customer service, 497 in manufacturing and logistics, and 691 in technology, corporate, management and administrative positions.

Talent Management
Our team members make a difference every day in improving society’s health and wellbeing through higher quality sleep. We engage our team members with an inclusive culture that is built on individuality and wellbeing. We celebrate individuality in each other, in our own lives and in our customers’ lives. We embrace every individual’s unique talents, perspectives and experiences and strive to create an environment where we can be our best selves. Valuing diversity, equity and inclusion makes us stronger, smarter and fuels our innovation and teamwork. Individuality connects us to our vision of becoming one of the world’s most beloved brands by delivering an unparalleled sleep experience.
Our culture embraces the shared values of passion, integrity, innovation, courage and teamwork. These values are central to who we are as a team and our ability to attract, engage, motivate and retain talent. Our holistic approach to talent management, as described below, is critical to the execution of our consumer innovation strategy. Talent management at Sleep Number is not a cyclical process but instead is a continuous lifecycle centered on learning and development. It comes to life through a 70/20/10 learning philosophy: (i) 70% of learning is on-the-job; (ii) 20% happens through managers, peers and others; and (iii) 10% is formal training or development. Our leaders have a strong commitment to seeing that this approach to talent management is successfully carried out every day. Some of the metrics that we use to gauge our progress include:
•We track numerous talent recruitment metrics to advance brand awareness and drive candidate traffic. This is used in our diversity hiring efforts. We also track retention and turnover of team members, including new hires on a monthly, quarterly and rolling 12-month basis. This is used to identify patterns and formulate talent strategies;
•We have a demographics dashboard that tracks race/ethnicity and gender by job grade, tenure and generation. This helps provide leaders with visibility to our progress on goals for diversity, equity and inclusion (DE&I). In 2020, we established a 13-member council of Sleep Number team members to advise the Company on advancing our DE&I initiatives;
•We have a continuous listening strategy to ensure we stay connected to the voice of our team members at critical times of the team member experience. The key survey touchpoints are at new hire, pulse check-in, annual engagement and exit. This allows leaders to monitor team member sentiment and key engagement metrics including an inclusion and belonging index. We also conducted a self-identification survey to learn how our team members identify and how they want to be appreciated as individuals;
•We benchmark at least annually all aspects of our total rewards program for team members. This ensures that we maintain a competitive rewards offering which is unique because all team members participate in some type of variable pay program (e.g., bonus, commissions) in addition to base pay. Our benefits package has been greatly expanded to support team member wellbeing including higher quality sleep by providing all 4,700 of our team members with a Sleep Number 360 smart bed in 2020, and a commitment to do so for all new Sleep Number team members going forward;
•We utilize our human capital management (HCM) system to track and follow team member performance assessments and development plans. We use our HCM system to monitor the completion of learning courses for our team members. Our enterprise learning management system provides all team members access to a training curriculum that is dynamic and mobile-accessible; and
•We collect and analyze workplace injury and accident information across all our locations. This enables our commitment to safety and dedication to reduce incident rates, number of workers’ compensation claims and lost workdays.
Social Impact Commitment
At Sleep Number, our purpose is to improve the health and wellbeing of society through higher quality sleep. We are committed to leveraging the power of sleep, and sleep science, to improve lives and create a healthier, kinder, more inclusive world. And because of our team’s dedication to our mission, disciplined execution of our vertically integrated business model and differentiated consumer innovation strategy, Sleep Number is at the forefront of delivering this life-changing benefit. With our revolutionary Sleep Number 360® smart beds and SleepIQ® technology, we have improved 13 million lives.
In 2018, we announced a social impact commitment to help one million young people achieve life-changing sleep through our products and sleep expertise by 2025. In 2020, we expanded our focus to broadly support children, families and communities, especially those who were deeply affected by the COVID-19 pandemic and social injustices. Our 2020 cash donations totaled over $600,000, and our team members donated their time and efforts to support individuals and families in need in their surrounding communities.
We improved the lives of nearly 100,000 individuals through continued partnerships with organizations including GENYOUth, Blue Star Families, American Cancer Society, Bridging and others. Additionally, we established new partnerships to make a greater
10

positive impact. On Giving Tuesday 2020, we announced a year-long partnership with Make-A-Wish to help critically ill Wish kids across the United States receive the quality sleep they need by providing new 360 smart beds. We also made a financial contribution to the National Urban League to support its important work to improve equality for Black Americans. In addition, because the health and wellbeing of our team members is a high priority, we provided all 4,700 Sleep Number team members with the gift of quality sleep in 2020, presenting each with a new Sleep Number 360 smart bed.
While our pioneering and award-winning innovations are designed to improve people's health and wellbeing through quality sleep, Sleep Number was able to improve the health and safety of frontline health-care workers in the early days of the COVID-19 pandemic in a different way. By leveraging resources at our Irmo South Carolina plant in early 2020, our manufacturing team supported the South Carolina Hospital Association by refurbishing nearly 50,000 N95 masks, fulfilling a much-needed supply amidst a personal protective equipment shortage.
Our Corporate Responsibility and Sustainability Report, posted within the Investor Relations section of our Company website, provides additional information about our commitment to talent management and human rights at Sleep Number, including strategy details, performance metrics and our engagement, beginning in 2020, with the United Nations Global Compact. The report highlights our commitments:

ITEM 1A. RISK FACTORS
An investment in our common stock involves a high degree of risk. You should carefully consider the specific risks set forth below and other matters described in this Annual Report on Form 10-K before making an investment decision. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties, including risks and uncertainties that impact the business environment generally, those not presently known to us, or those that we currently see as immaterial, may also harm our business. If any of these risks occur, our business, results of operations, cash flows and financial condition could be materially and adversely affected.
Risks Related to Consumer Sentiment and the Availability of Credit
The COVID-19 pandemic has had, and may continue to have, an adverse effect on our business and our financial results.
The COVID-19 pandemic has created significant volatility, uncertainty and economic disruption, which have adversely affected, and may continue to adversely affect, our business operations and our financial results. Consumer concern about becoming ill with the virus and recommendations and/or mandates from federal, state and local authorities to close certain businesses, stay at home, practice social distancing or self-quarantine resulted in the temporary closure of the majority of our stores nationwide for a period of time between mid-March and mid-May. Approximately 99% of our stores were open on average during the six months ended January 2, 2021. However, as the COVID-19 pandemic continues, we may need to further restrict the operations of our stores, delivery operations, and manufacturing and distribution facilities if we deem this necessary or if recommended or mandated by authorities, and these measures could have a further material impact on our sales and profits. Restrictions in 2020 adversely affected, and may in the future adversely affect, our business, operations, demand for our product, traffic to our stores, and macroeconomic factors that affect us, such as consumer confidence and spending, which have, in turn, resulted in a loss of sales and profits. Even as certain restrictions are eased or lifted, and vaccines and other treatments for COVID-19 become available, new or different restrictions may be implemented and consumers may continue to take additional precautions that could cause a reduction in foot-traffic to certain of our locations or other changes in consumer spending behavior over time. Moreover, as vaccines and other treatments for COVID-19 become available, consumer behavior may change, including spending more time away from home, and discretionary consumer spending on home goods such as our beds and related products may decrease.
With temporary closures to our retail store locations across the country at various points during 2020 and our delivery operations adversely impacted, we scaled our digital and “sell-from-anywhere” capabilities including: remote retail selling, customer service, private appointments, flexible work schedules, solutions for contactless delivery, and remote access for team members across the country. This shift to our team members working remotely has amplified certain risks to our business, including increased demand on our information technology resources and systems and increased risk of cybersecurity breaches and IT outages. In addition, as recommendations and/or mandates have been modified, eased or lifted across the country, we have implemented new health and safety policies at headquarters, stores, and our manufacturing and assembly locations as well as for our home delivery teams, which are intended to ensure the safety of our team members and customers and reduce the risk of contracting or spreading the coronavirus for team members, contractors, and customers who are unable to perform their roles or transact business remotely. The return to working in-person presents the risk that our new health and safety policies may not adequately protect our team members, contractors, and customers from contracting or spreading the coronavirus.
In response to the COVID-19 pandemic, including the significant reduction in customer visits to, and spending at, our stores caused by COVID-19, we did and in some situations continue to take actions to maintain liquidity and reduce costs. It is possible that our cost reduction efforts may be insufficient to maintain adequate liquidity if our operations are further restricted or disrupted due to the COVID-19 pandemic or governmental recommendations or mandates that may result in material impact on our sales and profits.
Additionally, if we do not respond appropriately to the pandemic, or if customers do not perceive our response to be adequate for a particular region or our Company as a whole, we could suffer damage to our reputation and our brand, which could adversely affect our business and financial results in the future.
We are highly dependent on the effectiveness of our marketing messages and the efficiency of our advertising expenditures in generating consumer awareness and sales of our products. In light of our adjustments due to COVID-19 and the overall fluid nature of the pandemic and the consumer environment, we may not be as successful in developing effective messages and achieving efficiency in our advertising expenditures.
14

Our business depends heavily on the uninterrupted operation of our two main manufacturing plants located in Irmo, SC and Salt Lake City, UT as well as our assembly distribution centers, two of which are co-located at the manufacturing plants and others located in Baltimore, MD and the greater Los Angeles, CA area. Our business also depends on the successful operation of our bedding collection fulfillment center in Brooklyn Park, MN and headquarters in Minneapolis, MN. The operation of all of our facilities is critically dependent on our team members who staff these locations, and COVID-19 could directly threaten or impact their health and/or ability to work, and, therefore, adversely affect the operations of our facilities. In addition, COVID-19 and governmental mandates or recommendations in these jurisdictions could require closures of our facilities and otherwise limit or adversely impact our ability to continue these operations.
In addition to our retail stores and home delivery operations, COVID-19 has also impacted, and may continue to impact, our logistics and domestic and foreign supply chain, including availability of raw materials and components we or our suppliers source from third parties as well as our sole source of supply for adjustable foundations, particularly as a result of governmental mandates or recommendations. We expect that these impacts will continue in 2021.
Our temporary reduction of discretionary spending across the Company and the inability or limitations of certain suppliers, both domestic and foreign, to operate due to governmental mandates or recommendations has delayed and may continue to delay the introduction of new product lines.
The situation surrounding COVID-19 remains fluid, and the potential for an adverse effect on our business and our financial results increases the longer the virus impacts activity levels in the United States and globally. For this reason, we cannot reasonably estimate with any degree of certainty the extent of the impact COVID-19 will have on our business. The extent and duration of the impact of COVID-19 on our business, operations, and financial results will depend on future developments, including the duration and spread of the outbreak, the availability, administration, and efficacy of vaccines, governmental mandates and recommendations, business and workforce disruptions, and the related impact on consumer confidence and spending, all of which are highly uncertain and unpredictable.
Current and future economic conditions could materially adversely affect our sales, profitability, cash flows and financial condition.
Our success depends significantly upon discretionary consumer spending, which is influenced by a number of general economic factors, including without limitation economic growth, consumer confidence, the housing market, employment and income levels, interest rates, inflation, taxation, consumer shopping trends and the level of customer traffic in malls and shopping centers, civil unrest, as well as the COVID-19 pandemic. Adverse trends in any of these economic factors may adversely affect our sales, profitability, cash flows and financial condition.
A reduction in the availability of credit to consumers generally or under our existing consumer credit programs could harm our sales, profitability, cash flows and financial condition.
A significant percentage of our sales are made under consumer credit programs through third parties. The amount of credit available to consumers may be adversely impacted by macroeconomic factors, including those related to or resulting from the COVID-19 pandemic, that affect the financial position of consumers, and as suppliers of credit adjust their lending criteria.
Synchrony Bank provides credit to our customers through a private label credit card agreement that is currently scheduled to expire on December 31, 2023, subject to earlier termination upon certain events. Synchrony Bank has discretion to control the content of financing offers to our customers and to set minimum credit standards under which credit is extended to customers.
Reduction of credit availability due to changing economic conditions, changes in credit standards under our private label credit card program or changes in regulatory requirements, or the termination of our agreement with Synchrony Bank, could harm our sales, profitability, cash flows and financial condition.
Risks Related to Our Marketing Strategy and Execution of Total Retail Distribution Strategy
Our future growth and profitability depend upon the effectiveness and efficiency of our marketing programs.
We are highly dependent on the effectiveness of our marketing messages and the efficiency of our advertising expenditures in generating consumer awareness and sales of our products. We continue to evolve our marketing strategies, adjust our messages, and
15

review the amount we spend on advertising and where we spend it. We may not always be successful in developing effective messages, as the consumer and competition change, or in achieving efficiency in our advertising expenditures.
We rely in part upon third parties, such as social media influencers and athletes, to market our brand, and we are unable to fully control their efforts. Influencers and athletes with whom we maintain a relationship could engage in behavior or use their platforms to communicate directly with our customers in a manner that reflects poorly on our brand, and these communications may be attributed to us or otherwise adversely affect us. It is not possible to prevent such behavior, and the precautions we take to detect or prevent this activity may not be effective.
Consumers are increasingly using digital tools as a part of their shopping experience. As a result, our future growth and profitability will depend in part on (i) the effectiveness and efficiency of our online experience, including without limitation advertising and search optimization programs, in generating consumer awareness and sales of our products; (ii) our ability to prevent confusion among consumers that can result from search engines that allow competitors to use our trademarks to direct consumers to competitors’ websites through confusing or misleading advertisements; (iii) our ability to prevent Internet publication of false or misleading information regarding our products or our competitors’ products; (iv) reviews of our products; (v) the nature and tone of consumer sentiment, including those published online or elsewhere; and (vi) the stability of our website. In recent periods, competitor spending on Internet-based marketing programs has increased, including without limitation from a number of direct-to-consumer, Internet-based retailers, which has and may continue to increase the cost of basic search terms and the cost of our Internet-based marketing programs.
If our marketing messages are ineffective or our advertising expenditures and other marketing programs, including digital programs, are inefficient in creating awareness and consideration of our products and brand name, and in driving consumer traffic to our website, call centers, or stores, our sales, profitability, cash flows and financial condition may be adversely impacted. In addition, if we are not effective in preventing the publication of confusing, false or misleading information regarding our brand or our products, or if there is publication online or elsewhere of significant negative consumer sentiment regarding our Company, brand or our products, our sales, profitability, cash flows and financial condition may be adversely impacted.
Our future growth and profitability depend on our ability to execute our Total Retail distribution strategy.
The vast majority of our sales occur through Total Retail, including our retail stores and our website. Total Retail represents our largest opportunity for growth in sales and improvement in profitability. Our retail stores carry significant fixed costs. We also make significant capital expenditures as we open new stores and remodel or reposition existing stores. We are highly dependent on our ability to maintain and increase sales per store to cover these fixed expenses, provide a return on our capital investments and improve our operating margins.
Some of our stores are mall-based. We depend on the continued popularity of malls as shopping destinations and the ability of mall anchor tenants and other attractions to generate customer traffic for our mall-based retail stores. Any decrease in mall traffic, including due to governmental recommendation or mandates related to COVID-19, could adversely affect our sales, profitability, cash flows and financial condition.
Our Total Retail distribution strategy results in relatively few points of distribution, including 602 retail stores in 50 U.S. states as of the end of 2020, Online, Phone and Chat. Several of the mattress manufacturers and retailers with which we compete have significantly more brick-and-mortar points of distribution than we do, which makes us highly dependent on our ability to drive consumers to our points of distribution to gain market share.
Our longer-term Total Retail distribution strategy is also dependent on our ability to renew existing store leases and to secure suitable locations for new store openings, in each case on a cost-effective basis. We may encounter higher than anticipated rents and other costs in connection with managing our retail store base. We may also be unable to find or obtain suitable new locations.
Failure to achieve and maintain a high level of product quality could negatively impact our sales, profitability, cash flows and financial condition.
Our products are highly differentiated from traditional innerspring mattresses and from viscoelastic and other foam mattresses, which have little or no technology and do not rely on electronics and air control systems. As a result, our beds may be susceptible to failures that do not exist with traditional or foam mattresses. Failure to achieve and maintain acceptable quality standards could impact consumer acceptance of our products or result in negative media and Internet reports or owner dissatisfaction that could negatively impact our brand image and sales levels.
16

In addition, a decline in product quality could result in an increase in return rates and a corresponding decrease in sales, or an increase in product warranty claims in excess of our warranty reserves. An unexpected increase in return rates or warranty claims could harm our sales, profitability, cash flows and financial condition.
As a consumer innovation Company with differentiated products, we face an inherent risk of exposure to product liability claims or regulatory actions if the use of our products is alleged to have resulted in personal injury or property damage. If any of our products proves to be defective or non-compliant with applicable regulations such as the federal Consumer Product Safety Commission flammability standards, we may be required to recall or redesign such products. We have at times experienced increased returns and adverse impacts on sales, as well as product liability litigation, as a result of media reports related to the alleged propensity of our products to develop mold. We may experience additional adverse impacts on sales and additional litigation if any similar media reports were to occur in the future. We maintain insurance against some forms of product liability claims, but such coverage may not be applicable to, or adequate for, liabilities actually incurred. A successful claim brought against us outside of, or in excess of, available insurance coverage, or any claim or product recall that results in significant adverse publicity about us, may have a material adverse effect on our sales, profitability, cash flows and financial condition.
Our future growth and profitability depend in part on our ability to continue to improve and expand our product line and to successfully execute new product introductions.
As described in greater detail below, the bedding industry, as well as the market for sleep monitoring products, are both highly competitive, and our ability to compete effectively and to profitably grow our market share depend in part on our ability to continue to improve and expand our product line of adjustable firmness air beds, SleepIQ technology and related accessory products. We incur significant research and development and other expenditures in the pursuit of improvements and additions to our product line. If these efforts do not result in meaningful product improvements or new product introductions, or if we are not able to gain widespread consumer acceptance of product improvements or new product introductions, our sales, profitability, cash flows and financial condition may be adversely affected. In addition, if any significant product improvements or new product introductions are not successful, our reputation and brand image may be adversely affected.
Our intellectual property rights may not prevent others from using our technology or trademarks in connection with the sale of competitive products. We are from time to time subject to claims that our products, processes or trademarks infringe intellectual property rights of others.
We own various U.S. and foreign patents and patent applications related to certain elements of the design and function of our beds and related products. We own numerous registered and unregistered trademarks and trademark applications, including in particular our Sleep Number, Sleep Number 360, 360, and SleepIQ trademarks, as well as other intellectual property rights, including trade secrets, trade dress and copyrights, which we believe have significant value and are important to the marketing of our products. These intellectual property rights may not provide adequate protection against infringement or piracy, may not prevent competitors from developing and marketing products that are similar to or competitive with our beds or other products, and may be costly and time-consuming to protect and enforce. Our patents are also subject to varying expiration dates. In addition, the laws of some foreign countries may not protect our intellectual property rights and confidential information to the same extent as the laws of the United States. If we are unable to protect and enforce our intellectual property, we may be unable to prevent other companies from using our technology or trademarks in connection with competitive products, which could adversely affect our sales, profitability, cash flows and financial condition.
We are from time to time subject to claims that our products, processes, advertising, or trademarks infringe the intellectual property rights of others. The defense of these claims, even if we are ultimately successful, may result in costly litigation, and if we are not successful in our defense, we could be subject to injunctions and liability for damages or royalty obligations, and our sales, profitability, cash flows and financial condition could be adversely affected.
Risks Related to Our Reliance on Third Parties and Reliance on a Global Supply Chain
We could be vulnerable to shortages in supply of components necessary to manufacture our products due to our manufacturing processes which operate with minimal levels of inventory or due to global shortages of supply of electronic componentry or other materials, which may harm our ability to satisfy consumer demand and may adversely impact our sales and profitability.
A significant percentage of our products are assembled after we receive orders from customers utilizing manufacturing processes with minimal levels of raw materials, work-in-process and finished goods inventories. Lead times for ordered components may vary significantly, and some components used to manufacture our products are provided on a sole source basis. In addition, with the
17

increasing prevalence of and consumer demand for electronic products, the global supply of electronic componentry is increasingly strained, which may lead to shortages in supply and increased prices. Any unexpected shortage of materials caused by any disruption
or unavailability of supply or an unexpected increase in the demand for our products, could lead to delays in deliveries of our products to customers and increased costs. Any such delays could adversely affect our sales, customer satisfaction, profitability, cash flows and financial condition.
We rely upon several key suppliers and third parties that are, in some instances, the only source of supply or services currently used by us for particular materials, components, products or services. A disruption in the supply or substantial increase in cost of any of these products or services could harm our sales, profitability, cash flows and financial condition.
We currently obtain all the materials and components used to produce our beds from outside sources including some that are located outside the United States. In several cases, including our air chambers, integrated non-adjustable foundations, adjustable foundations, various components for our Firmness Control systems, certain foam formulations, as well as our fabrics and zippers, we have chosen to obtain these materials, components and products from suppliers who serve as the only source of supply, or who supply the vast majority of our needs of the particular material, component or product. While we believe that these materials, components and products, or suitable replacements, could be obtained from other sources in the event of a disruption or loss of supply, we may not be able to find alternative sources of supply or alternative sources of supply on comparable terms. If our relationship with the primary supplier of our air chambers or the supplier of our adjustable foundations is terminated, we could have difficulty in replacing these sources since there are relatively few other suppliers presently capable of manufacturing these components and products. Constraints on the ability of certain of our suppliers to timely meet commitments in an environment of increased demand for consumer products and reduced labor during the COVID-19 pandemic, which has, and may continue to, adversely impact our ability to meet our product demand, result in additional costs, or may otherwise adversely impact our business, operations and financial condition.
Similarly, we rely on third parties to deliver some of our products to our facilities and customers on a timely and cost-effective basis. These third-party providers could be vulnerable to labor shortages, liquidity concerns or other factors that may result in delays in deliveries or increased costs of deliveries. Any significant delay in deliveries to our customers could lead to increased returns and cause us to lose sales. Any increase in freight charges or other costs of deliveries could increase our costs of doing business and harm our sales, profitability, cash flows and financial condition.
Fluctuations in commodity prices or third-party logistics costs could result in an increase in component costs and/or delivery costs.
Our business is subject to significant increases or volatility in the prices of certain commodities, including but not limited to electronic componentry, fuel, oil, natural gas, rubber, cotton, plastic resin, corrugate, steel and chemical ingredients used to produce foam, as well as third-party logistic costs. Increases in prices of these commodities or logistics costs or other inflationary pressures may result in significant cost increases for our raw materials and product components, as well as increases in the cost of delivering our products to our customers. To the extent we are unable to offset any such increased costs through value engineering and similar initiatives, or through price increases, our profitability, cash flows and financial condition may be adversely impacted. If we choose to increase prices to offset the increased costs, our sales volumes could be adversely impacted.
Our business is subject to risks inherent in global sourcing activities.
Our air chambers and some of our other components are manufactured outside the United States, and therefore are subject to risks associated with foreign sourcing of materials, including but not limited to:
•Existing or potential duties, tariffs or quotas on certain types of goods that may be imported into the United States;
•Political instability resulting in disruption of trade;
•Disruptions in supply or transportation due to acts of terrorism, outbreaks of pandemics or contagious diseases (such as the COVID-19 pandemic), shipping delays, foreign or domestic strikes, customs inspections or other factors;
•Foreign currency fluctuations; and
•Economic uncertainties, including inflation.
We cannot predict whether the countries in which some of our components are manufactured, or may be manufactured in the future, will be subject to new or additional trade restrictions imposed by the United States or other foreign governments, including the likelihood, type, or effect of any such restrictions. The United States government has commenced certain trade policies, including imposing tariffs on certain goods imported from China and other countries, and may take further actions with respect to these policies
18

in the future. These factors could increase our costs of doing business with foreign suppliers, lead to inadequate inventory levels or delays in shipping beds to our customers, which could harm our sales, customer satisfaction, profitability, cash flows and financial condition.
Our operations and those of our suppliers are located in various regions of the U.S. and across the globe, which subjects us to regional risks, such as adverse weather conditions and other natural or man-made disasters.
The locations where we and our suppliers operate have experienced, and may experience in the future, adverse regional events such as extreme weather conditions and other natural and man-made disasters, which could have a material adverse effect on us and our ability to source necessary materials, components and products. Climate change may increase the frequency and severity of adverse weather conditions and other natural disasters. The western and southern regions of the U.S. and warmer climates globally may be particularly impacted by extreme weather, such as hurricanes, natural disasters, wildfires and rising sea levels. These events may disrupt our operations and ability to source components and products.
Climate change continues to draw scientific, governmental, and public attention. Many scientists, legislators and others attribute climate change to increased levels of greenhouse gas emissions, including carbon dioxide, which has led to legislative and regulatory efforts to limit such emissions. The enactment of new laws and regulations, or changes to existing laws and regulations, could mandate more restrictive standards or require such changes on a more accelerated time frame. There continues to be a lack of consistent climate legislation, which creates economic and regulatory uncertainty. The consequences of climate change and the ensuing patchwork of governmental regulations and orders could disrupt our operations or harm our ability to source necessary materials and components and manufacture our products. If public perception of our compliance with laws and regulations related to climate change is negative, it could adversely affect our business and reputation.
Risks Related to Our Vertically Integrated Business
Significant competition could adversely affect our business.
Because of the vertical integration of our business model, our products and distribution face significant competition from both manufacturers of different types of mattresses and a variety of retailers. Our SleepIQ technology also faces significant competition from various manufacturers and retailers of sleep tracking and monitoring products.
The mattress industry is characterized by a high degree of concentration among the largest manufacturers of innerspring mattresses and foam mattresses and one dominant national mattress retailer. In recent years, numerous direct-to-consumer companies and low-cost importers have entered the market, offering “bed-in-a-box” or similar products primarily through online distribution directly to consumers though many now also partner with traditional mattress retailers. The emergence of these new competitors has significantly increased the costs of search terms and digital advertising.
A variety of sleep tracking and monitoring products that compete with our SleepIQ technology have been introduced by various manufacturers and retailers, both within and outside of the traditional mattress industry.
Some of our competitors have substantially greater financial, marketing and manufacturing resources and greater brand name recognition than we do and sell products through broader and more established distribution touchpoints. Our national, exclusive distribution competes with other retailers who generally provide a wider selection of mattress alternatives than we offer. A number of these retailers also have more points of distribution, greater marketing resources, and greater brand name recognition than we do.
These manufacturing and retailing competitors, or new entrants into the market, may compete aggressively and gain market share with existing or new products, and may pursue or expand their presence in the adjustable firmness air bed segment of the market as well as in the market for sleep tracking and monitoring products. We have limited ability to anticipate the timing and scale of new product introductions, advertising campaigns or new pricing strategies by our competitors, which could inhibit our ability to retain or increase market share, or to maintain our profit margins.
If we are unable to effectively compete with other manufacturers and retailers of mattress and sleep tracking and monitoring products, our sales, profitability, cash flows and financial condition may be adversely impacted.
Disruption of operations in our main manufacturing facilities or assembly facilities could increase our costs of doing business or lead to delays in shipping our beds.
19

We have two main manufacturing plants, which are located in Irmo, South Carolina and Salt Lake City, Utah. We have several assembly distribution centers, which assemble the final mattress product before delivery to the customer, across the US. A significant
percentage of our products are assembled to fulfill orders rather than stocking finished goods inventory in our plants or stores. Therefore, the disruption of operations of either of our two main manufacturing plants or our assembly distribution centers for a significant period of time may increase our costs of doing business and lead to delays in deliveries of our products to customers. Such delays could adversely affect our sales, customer satisfaction, profitability, cash flows and financial condition.
Risks Related to Legal Compliance and Legal Proceedings
Our business is subject to a wide variety of government laws and regulations. These laws and regulations, as well as any new or changed laws or regulations, could disrupt our operations or increase our compliance costs. Failure to comply with such laws and regulations could have further adverse impacts on our operations.
We are subject to a wide variety of laws and regulations relating to the bedding industry or to various aspects of our business. Laws and regulations at the federal, state and local levels frequently change and we cannot always reasonably predict the impact from, or the ultimate cost of compliance with, future regulatory or administrative changes. Changes in law, the imposition of new or additional regulations or the enactment of any new or more stringent legislation that impacts employment and labor, trade, advertising and marketing practices, pricing, consumer credit offerings, “do not call/mail” requirements, text messaging requirements, product testing and safety, transportation and logistics, health care, tax, accounting, privacy and data security, health and safety or environmental issues, warranty disclosures, delivery timing requirements, accessibility requirements, among others, could require us to change the way we do business and could have a material adverse impact on our sales, profitability, cash flows and financial condition. New or different laws or regulations could increase direct compliance costs for us or may cause our vendors to raise the prices they charge us because of increased compliance costs. Further, the adoption of a multi-layered regulatory approach to any one of the state or federal laws or regulations to which we are currently subject, particularly where the layers are in conflict, could require alteration of our manufacturing processes or operational parameters which may adversely impact our business.
Legislative or regulatory changes that impact our relationship with our workforce, such as minimum wage requirements or health insurance or other employee benefits mandates, could increase our expenses and adversely affect our operations. While it is our policy and practice to comply with legal and regulatory requirements and our procedures and internal controls are designed to promote such compliance, we cannot assure that all of our operations will comply with all such legal and regulatory requirements. Further, laws and regulations change over time and we may be required to incur significant expenses and/or to modify our operations in order to ensure compliance. This could harm our profitability or financial condition. If we are found to be in violation of any laws or regulations, we could become subject to fines, penalties, damages or other sanctions as well as potential adverse publicity or litigation exposure. This could adversely impact our business, reputation, sales, profitability, cash flows or financial condition.
Pending or unforeseen litigation and the potential for adverse publicity associated with litigation could adversely impact our business, reputation, financial results or financial condition.
We are involved from time to time in various legal proceedings arising in the ordinary course of our business, including primarily commercial, product liability, employment and intellectual property claims. We currently do not expect the outcome of any pending matters to have a material effect on our consolidated results of operations, financial position or cash flows. Litigation, however, is inherently unpredictable, and it is possible that the ultimate outcome of one or more pending claims asserted against us, or claims that may be asserted in the future that we are currently not aware of, or adverse publicity resulting from any such litigation, could adversely impact our business, reputation, sales, profitability, cash flows and financial condition.
Risks Related to Our Information Systems and Cybersecurity
Information systems that contain confidential Company data, consumers’ private data, and team members’ private data may be subject to attacks by hackers or other cyber threats that could compromise the confidentiality, integrity, and availability of the data, which could substantially disrupt our business and could result in a breach of the data.
Our information systems and information systems of third-party vendors we use to assist in the storage and management of information contain personal information related to our customers and team members in the ordinary course of our business, such as credit card and demographic information of our customers, SleepIQ® data, including biometric data (e.g., sleep, physiological), from our customer base and social security numbers and demographic information of our team members. These information systems also contain confidential Company data regarding our business and innovations. While we maintain and require our third-party vendors to maintain security measures to protect this information, a breach of these security measures, such as through third-party action and
20

attacks, team member error, access to our data and systems, malfeasance or otherwise, could compromise the security of our data and customers’ and team members’ personal information. As the techniques used to breach such security measures change frequently and may not be recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventive measures. Any failure of our systems and processes or our third-party vendors’ systems and processes to adequately protect our data or customer or team member personal information from exposure, theft or loss could adversely impact our business, reputation, sales, profitability, cash flows and financial condition.
Any improvements or upgrades to information systems that may be required to meet the evolving needs of our business and cybersecurity needs as well as existing and emerging regulatory requirements may be costly to implement and may take longer or require greater resources than anticipated, and may result in disruptions to our systems or business.
We depend on our information systems for many aspects of our business. If our information systems are disrupted in any material way, or improvements or upgrades are required to meet the evolving needs of our business, cybersecurity needs, and existing and emerging regulatory requirements, we may be required to incur significant capital expenditures in the pursuit of improvements or upgrades to our information systems. These efforts may take longer and may require greater financial and other resources than anticipated, may cause distraction of key personnel, and may cause short-term disruptions or security vulnerabilities to our existing systems and our business. Any of these outcomes could impair our ability to achieve critical strategic initiatives and could adversely impact our sales, profitability, cash flows and financial condition.
Risks Related to Our Stock
A substantial amount of our stock is held by a small number of large investors and significant sales of our common stock by one or more of these holders could cause our stock price to fall, which could cause investors to lose all or a portion of their investment in our stock.
As of December 31, 2020, we believe the nine largest holders of common stock were institutional investors who held approximately 53% of our outstanding shares of common stock in the aggregate, with BlackRock Fund Advisors being our largest shareholder with approximately 14% of our outstanding shares of common stock. These investors may sell their shares at any time for a variety of reasons, and such sales could depress the market price of our common stock, which could cause investors to lose all or a portion of their investment in our stock. In addition, any such sales of our common stock by these entities could also impair our ability to raise capital through the sale of additional equity securities.
The stock price of our Company may fluctuate significantly in response to numerous factors such as: the overall performance of the equity markets and the economy as a whole; changes in the financial projections we or third parties may provide to the public or our failure to meet these projections; actual or anticipated changes in our growth rate relative to that of our competitors; failure of securities analysts to maintain coverage of us, changes in financial estimates by any securities analysts who follow our Company or our failure to meet these estimates or the expectations of investors; and sales of share of our common stock by us or our shareholders particularly sales by our directors, executive officers and significant shareholders or the perception that these sales could occur.
General Risks
Our future growth and profitability depend in part upon our ability to attract, retain and motivate qualified personnel.
As a vertically integrated manufacturer and retailer, our future growth and profitability will depend in part upon our ability to attract, retain and motivate qualified personnel in a wide variety of areas to execute our growth strategy, including qualified management and executive personnel and qualified retail sales professionals and managers. The failure to attract, retain and motivate qualified personnel may hinder our ability to execute our business strategy and growth initiatives and may adversely impact our sales, profitability, cash flows and financial condition.

ITEM 2. PROPERTIES
Retail Locations
We currently lease all of our existing retail store locations and expect that our policy of leasing stores, rather than owning stores, will continue. We lease our retail stores under operating leases which, in addition to the minimum lease payments, may require payment of a proportionate share of the real estate taxes and certain building operating expenses. Our retail store leases generally provide for an initial lease term of five to 10 years. In addition, our mall-based retail store leases may require payment of contingent rent based on net sales in excess of certain thresholds. Certain retail store leases may contain options to extend the term of the original lease.
The following table summarizes the geographic locations of our 602 retail stores as of January 2, 2021:

See pages 26 and 27 for the reconciliation of these non-GAAP measures to the appropriate GAAP measures.
Non-GAAP Data Reconciliations
Earnings before Interest, Taxes, Depreciation and Amortization (Adjusted EBITDA)
(in thousands)
We define earnings before interest, taxes, depreciation and amortization (Adjusted EBITDA) as net income plus: income tax expense, interest expense, depreciation and amortization, stock-based compensation and asset impairments. Management believes Adjusted EBITDA is a useful indicator of our financial performance and our ability to generate cash from operating activities. Our definition of Adjusted EBITDA may not be comparable to similarly titled definitions used by other companies. The table below reconciles Adjusted EBITDA, which is a non-GAAP financial measure, to the comparable GAAP financial measure:

Return on Invested Capital (ROIC)
(in thousands)
ROIC is a financial measure we use to determine how efficiently we deploy our capital. It quantifies the return we earn on our invested capital. Management believes ROIC is also a useful metric for investors and financial analysts. We compute ROIC as outlined below. Our definition and calculation of ROIC may not be comparable to similarly titled definitions and calculations used by other companies. The tables below reconcile net operating profit after taxes (NOPAT) and total invested capital, which are non-GAAP financial measures, to the comparable GAAP financial measures:

_____________________
(1) Rent expense is added back to operating income to show the impact of owning versus leasing the related assets.
(2)Depreciation is based on the average of the last five fiscal quarters’ ending capitalized operating lease obligations (see note 5) for the respective reporting periods with an assumed thirty-year useful life. This life assumption is based on our long-term participation in given markets though specific retail location lease commitments are generally five to 10 years at inception. This is subtracted from operating income to illustrate the impact of owning versus leasing the related assets.
(3)Reflects annual effective income tax rates, before discrete adjustments, of 23.5%, 24.0%, 24.1%, 33.3% and 33.0% for 2020, 2019, 2018, 2017 and 2016, respectively.
(4)Long-term debt includes existing finance lease liabilities.
(5)A multiple of eight times annual rent expense is used as an estimate for capitalizing our operating lease obligations. The methodology utilized aligns with the methodology of a nationally recognized credit rating agency.
(6)Average invested capital represents the average of the last five fiscal quarters’ ending invested capital balances.
(7)ROIC equals NOPAT divided by average invested capital.
Note - Our ROIC calculation and data are considered non-GAAP financial measures and are not in accordance with, or preferable to, GAAP financial data. However, we are providing this information as we believe it facilitates analysis of the Company’s financial performance by investors and financial analysts.

COVID-19 Pandemic - Impact on our Business
At the onset of the COVID-19 pandemic in mid-March 2020, government restrictions resulted in the temporary closure of most of our retail stores. While prioritizing the safety of our team, serving our customers and ensuring business continuity, we swiftly took decisive actions to strengthen our liquidity, cash flows and financial position, and mitigate the future impact on our operations and financial performance.
Despite a 20% decline in net sales during the three months ended June 27, 2020 when 47% of our stores were closed on average, 2020 net sales increased 9% and net income increased by 70% compared with the same period one year ago. Approximately 99% of our stores were open on average during the six months ended January 2, 2021.
While we generated strong financial performance during 2020, the volatility, length and severity of the pandemic's impact on consumer demand and the resulting impact on our future financial performance remains uncertain. See Part I: Item 1A. Risk Factors, for additional discussion on the COVID-19 pandemic and the impact on our business.
Health and Safety of our Team Members and Customers. Upon onset of the COVID-19 pandemic, we implemented precautionary and sanitary guidelines throughout our operations, including stores, manufacturing, home delivery and headquarters based on the Centers for Disease Control and Prevention’s (CDC) recommendations, and other best practices.
Expense Management. With the reduction in second-quarter 2020 revenue due to the pandemic, we implemented appropriate expense management actions, including:
•In April 2020, we furloughed nearly 40% of our team members with another 30% working reduced hours. T he majority of our team members returned to work as stores reopened and customer demand increased. In response to changes in the business, we restructured some teams, which resulted in approximately 10% of positions nationwide being eliminated as we reallocated headcount to support the changing needs of our business;
•We temporarily reduced our sales and marketing expenses. For all of 2020, we increased media spending 4% year-over-year, supporting the 9% increase in net sales; and
•We negotiated rent deferrals and abatements for stores closed due to COVID-19.
Liquidity, Cash Flows and Financial Position. We took the following actions to preserve cash, increase liquidity and strengthen our financial position:
•Added $75 million of additional liquidity on April 3, 2020 through an incremental 364-day term loan under our credit facility’s $150 million accordion. On September 24, 2020, we repaid the $75 million term loan with cash provided by operating activities;
29

•In March 2020, temporarily suspended share repurchases under our Board-approved share repurchase program. In October 2020, resumed share repurchases and repurchased $190 million of our common stock ($71.44 per share, based on trade dates) during the three months ended January 2, 2021;
•Temporarily reduced capital expenditures to $37 million for 2020, compared with $59 million during 2019. We remained committed to our long-term innovation initiatives, including investing $41 million in research and development expenses during 2020, 17% more than the prior year;
•Net liquidity available under our credit facility was $202 million at January 2, 2021; and
•Our leverage ratio as defined in our credit agreement was 2.2x as of January 2, 2021. The maximum leverage ratio under our credit agreement is 4.5x.
CARES Act. On March 27, 2020, the President signed the Coronavirus Aid, Relief, and Economic Security Act (the CARES Act) into law. The CARES Act includes the following relief, among others:
•Amended federal tax laws to permit 100% bonus depreciation for eligible qualified improvement property placed in service by the taxpayer after December 31, 2017 and before January 1, 2023;
•Employers were eligible for a 50 percent refundable payroll tax credit on wages paid up to $10,000, per employee, during 2020. The credit was available to employers whose businesses were disrupted due to virus shutdowns and those that had a decrease in gross receipts of 50 percent or more when compared to the same quarter in the prior year. The credit could be claimed for employees who are retained but not currently working due to the crisis for firms with more than 100 employees; and
•Provided for deferred payment of the employer portion of social security taxes through the end of 2020, with 50% of the deferred amount due December 31, 2021 and the remaining 50% due December 31, 2022. This has provided us with additional liquidity during 2020.
Results of Operations
Fiscal 2020 Summary
Financial highlights for fiscal 2020 were as follows:
•Net sales for 2020 increased 9% to $1.9 billion, compared with $1.7 billion in 2019. Total Retail comparable sales increased 6% and sales from net opened/closed stores in the past 12 months added 1.5 percentage points (ppt.) of growth in 2020. In addition, 2020 included 53 weeks compared with 52 weeks in the prior year, with the extra week benefiting 2020 net sales by $41 million. For additional details, see the components of total net sales growth on page 31.
•Sales per store in 2020 (Total Retail sales for stores open at least one year, including Online, Phone and Chat sales, adjusted for the additional 53rd week) on a trailing twelve-month basis totaled $3.1 million, 6% higher than 2019.
•2020 operating income of $185 million increased by $73 million, or 65%, compared with $112 million in the prior year. Our 2020 operating income rate increased to 10.0% of net sales, compared with 6.6% of net sales in 2019. Our 2020 operating income and operating income rate were positively impacted by the 9% increase in net sales, a 0.4 ppt. increase in our gross profit rate and 3.0 ppt. reduction in our operating expense rate.
•We continued to prioritize investments in near- and long-term growth drivers in 2020, including a 17% increase in our innovation driving R&D expenses.
•Net income in 2020 increased 70% to $139 million, compared with net income of $82 million in 2019. Net income per diluted share increased 81% to $4.90, compared with $2.70 per diluted share in 2019. Diluted earnings per share for 2020 benefited from the profits generated during the additional 53rd week ($0.30 per diluted share).
•We achieved a return on invested capital (ROIC) of 25.0% in 2020, compared with 17.8% in 2019.
•Cash provided by operating activities in 2020 increased by 48% to $280 million, compared with $189 million for the prior year. Purchases of property and equipment for 2020 decreased to $37 million, compared with $59 million in 2019. The year-over-year decrease was primarily due to actions taken to temporarily reduce capital spending based on the economic uncertainties associated with the pandemic.
•We ended 2020 with $244 million of borrowings under our credit facility, compared with $231 million at the end of 2019. Net liquidity available under our credit facility was $202 million at January 2, 2021. Our leverage ratio as defined in our credit agreement was 2.2x as of January 2, 2021. The maximum leverage ratio under our credit agreement is 4.5x.
•In 2020, we invested $228 million to repurchase 3.4 million shares of our common stock ($66.49 per share, based on trade dates) under our Board-approved share repurchase program. As of January 2, 2021, the remaining authorization under our Board-approved share repurchase program was $247 million.

Comparison of 2020 and 2019
Net sales
Net sales in 2020 increased 9% to $1.9 billion, compared with $1.7 billion in 2019. The sales increase was driven by a 6% comparable sales increase in Total Retail and 1.5 percentage points (ppt.) of growth from net opened/closed stores in the past 12 months. In addition, 2020 included 53 weeks compared with 52 weeks in the prior year, with the extra week benefiting 2020 net sales by $41 million. Online, Phone and Chat sales (included in comparable sales noted above) made up 15% of total net sales compared with 8% in the prior year as consumers embrace transacting remotely with Sleep Number as well as in our stores. For additional details, see the components of total net sales growth on page 31.
The $158 million net sales increase compared with the same period one year ago was primarily comprised of: (i) a $90 million increase from Total Retail comparable sales; (ii) $41 million from the additional 53rd week; and (iii) a $33 million increase resulting from net opened/closed stores; partially offset by (iii) a $6 million decrease in Wholesale/Other sales. Total Retail mattress units increased 10% compared to the prior-year period. Average revenue per mattress unit in Total Retail of $4,856 remained consistent year over year.
Gross profit
Gross profit for 2020 of $1.2 billion increased by $104 million, or 9.9%, compared with $1.1 billion in 2019. The 2020 gross profit rate increased to 62.3% of net sales, compared with 61.9% for the prior-year period. The 0.4 ppt. increase in the gross profit rate was mainly due to: (i) leverage from the 9% net sales increase and efficiency initiatives (0.6 ppt.); partially offset by (ii) higher performance-based incentive compensation expense (0.2 ppt.). In addition, our gross profit rate will fluctuate from quarter-to-quarter due to a variety of other factors, including return and exchange costs.
32

Sales and marketing expenses
Sales and marketing expenses totaled $771 million in 2020, compared with $767 million last year. The sales and marketing expense rate decreased to 41.5% of net sales, compared with 45.2% for the same period one year ago. The current-year sales and marketing expenses rate decrease of 3.7 ppt. was primarily due to: (i) actions taken to manage expenses in response to the uncertainty related to the COVID-19 pandemic; and (ii) the leveraging impact of the 9% net sales increase. Expense management actions included leveraging our media spending, which increased by 4% compared with the prior year, while net sales increased by 9%, and lower payroll costs due to reduced store operating hours and improved productivity.
General and administrative expenses
General and administrative (G&A) expenses increased $21 million to $159 million in 2020, compared with $138 million in the prior year and increased to 8.6% of net sales, compared with 8.1% of net sales one year ago. The $21 million increase in G&A expenses consisted of the following major components: (i) a $21 million increase in employee compensation primarily resulting from a year-over-year increase in Company-wide performance-based incentive compensation; and (ii) a $2 million increase in miscellaneous other expenses; partially offset by (iii) a $2 million decrease in travel and training expenses. The G&A expenses rate increased by 0.5 ppt. in the current-year period, compared with the same period one year ago due to the items discussed above, partially offset by the leveraging impact of the 9% net sales increase.
Research and development expenses
Research and development (R&D) expenses increased by 17% to $41 million in 2020, compared with $35 million in 2019. The R&D expense rate for 2020 increased to 2.2% of net sales, compared with 2.1% of net sales for the prior year. The 17% spending level increase supports our consumer innovation strategy.
Interest expense, net
Interest expense, net decreased to $9 million for the year ended January 2, 2021, compared with $12 million for the same period one year ago. The $3 million interest expense reduction was driven by lower average borrowings under credit facility in 2020 and a decrease in the weighted-average interest rate on borrowings outstanding during 2020 compared with 2019.
Income tax expense
Income tax expense was $37 million for the year ended January 2, 2021, compared with $19 million for the same period one year ago. Both periods benefited from discrete tax items. The effective income tax rate for the year ended January 2, 2021 was 20.9% reflecting stock-based compensation excess tax benefits. The effective income tax rate for the year ended December 28, 2019 was 18.6% reflecting stock-based compensation excess tax benefits, additional tax credits and the favorable resolution of a tax matter. See Note 11, Income Taxes, for further information.

Managing our liquidity and capital resources is an important part of our commitment to deliver superior shareholder value over time. At the onset of the COVID-19 pandemic in mid-March, government restrictions resulted in the temporary closure of most of our retail stores, with 47% of our retail stores on average closed during the three months ended June 27, 2020. Despite a 20% decline in net sales during the three months ended June 27, 2020, net sales increased 9% and net income increased by 70% in 2020 compared with 2019, and cash generated from operations increased 48%. Approximately 99% of our stores were open on average during the six months ended January 2, 2021. The actions below were taken to manage liquidity and capital resources during the initial stages of the COVID-19 pandemic. Our strong financial performance during the second half of 2020 has dramatically improved our risk profile and we have taken subsequent liquidity and capital deployment actions as a result.
•On September 24, 2020, we repaid the $75 million, 364-day term loan we added under our credit agreement on April 3, 2020. The $75 million term loan provided increased liquidity and preserved financial flexibility in consideration of the disruption and uncertainty resulting from the COVID-19 pandemic. On October 5, 2020, we amended the credit agreement to remove the share

repurchase restriction and eliminate the floor based on LIBOR of at least 0.75% from our $450 million credit agreement. Net liquidity available under our credit facility was $202 million at January 2, 2021.
•We resumed share repurchases under our Board-approved share repurchase program in October 2020, after it was temporarily suspended. We also reduced 2020 capital expenditures in response to COVID-19. We expect to return to a normalized amount of capital spending going forward.
•We negotiated rent deferrals and abatements for stores closed due to COVID-19.
•W e furloughed nearly 40% of our team members with another 30% working reduced hours. T he majority of our team members returned to work as stores reopened and customer demand increased. In response to changes in the business, we have restructured some teams, which resulted in approximately 10% of positions nationwide being eliminated as we reallocated headcount to support the changing needs of our business.
•We temporarily suspended the Company's 401(k) match and selected other benefit programs. In September 2020, we reinstated the discretionary 401(k) plan contributions for all of 2020.
•We also temporarily reduced our sales and marketing expenses, and most discretionary projects, while continuing to support our innovation initiatives. As our stores reopened and market conditions warranted, we increased our sales and marketing expenses, and restarted discretionary projects to support the future growth of business.
Our primary sources of liquidity are cash flows provided by operating activities and cash available under our $450 million revolving credit facility. As of January 2, 2021, we do not have any off-balance sheet financing other than our $4 million in outstanding letters of credit. The cash generated from ongoing operations and cash available under our revolving credit facility are expected to be adequate to maintain operations and fund anticipated expansion, strategic initiatives and contractual obligations such as lease payments and capital commitments for new retail store locations for the foreseeable future. See Notes 7, Leases, and 12, Commitments and Contingencies, for further details on our contractual obligations.
Cash and cash equivalents totaled $4 million and $2 million at January 2, 2021 and December 28, 2019, respectively. Significant changes in cash and cash equivalents during 2020 included $280 million of cash provided by operating activities, which were offset by $37 million of cash used to purchase property and equipment, $236 million of cash used to repurchase our common stock and a $12 million decrease in short-term borrowings.
The following table summarizes our cash flows (dollars in millions). Amounts may not add due to rounding differences:

| 2020 |  | 2019
Total cash provided by (used in): |  |  |
Operating activities | $ | 279.7 |  |  | $ | 189.2 |
Investing activities | (39.0) |  |  | (56.6) |
Financing activities | (238.0) |  |  | (132.6) |
Net change in cash and cash equivalents | $ | 2.7 |  |  | $ | 0.0 |

Cash provided by operating activities for the fiscal year ended January 2, 2021 was $280 million compared with $189 million for the fiscal year ended December 28, 2019. Significant components of the $91 million year-over-year increase in cash from operating activities included: (i) a $57 million increase in net income in 2020 compared with 2019; (ii) a $31 million fluctuation in customer prepayments due to the strong recovery in customer demand during the last six months of 2020 that outperformed forecasts and suppliers' fulfillment, which had been curtailed to navigate the challenges of the COVID-19 pandemic; (iii) a $27 million fluctuation in accounts payable with both years impacted by business changes and timing of payments; and (iv) a $24 million fluctuation in the amount of compensation and benefits accrued and timing of the related payments resulting from year-over-year changes in Company-wide performance-based incentive compensation.
Net cash used in investing activities was $39 million for the fiscal year ended January 2, 2021, compared with $57 million in 2019. Investing activities in 2020 included $37 million of property and equipment purchases, compared with $59 million last year. The year-over-year decrease was primarily due to actions taken to temporarily reduce capital spending based on the economic uncertainties associated with the pandemic.
Net cash used in financing activities was $238 million for the fiscal year ended January 2, 2021, compared with $133 million in 2019. During the fiscal year ended January 2, 2021, we repurchased $236 million of our common stock (based on settlement dates, $229 million under our Board-approved share repurchase program and $7 million in connection with the vesting of employee restricted stock grants), compared with $165 million in 2019. Short-term borrowings decreased by $12 million during 2020 due to a $13 million

increase in borrowings under our credit facility to $244 million, which was more than offset by a decrease in book overdrafts which are included in the net change in short-term borrowings. Short-term borrowings increased by $26 million during 2019 due to a $31 million increase in borrowings under our credit facility to $231 million, partially offset by a decrease in book overdrafts. Financing activities for both years reflect the cash proceeds from the exercise of employee stock options.
Under our Board-approved share repurchase program, we repurchased 3.4 million shares at a cost of $228 million (based on trade dates, $66.49 per share) during the fiscal year ended January 2, 2021. During 2019, we repurchased 3.6 million shares at a cost of $146 million ($40.97 per share). As of January 2, 2021, the remaining authorization under our Board-approved share repurchase program was $247 million. There is no expiration date governing the period over which we can repurchase shares.
As of January 2, 2021, we had $244 million of borrowings under our credit facility. We also had $4 million in outstanding letters of credit. Net liquidity available under our credit facility was $202 million at January 2, 2021. The credit agreement provides the lenders with a collateral security interest in substantially all of our assets and those of our subsidiaries and requires us to comply with, among other things, a maximum leverage ratio (4.5x) and a minimum interest coverage ratio (3.0x). Our leverage ratio as defined in our credit agreement was 2.2x as of January 2, 2021. The credit agreement includes an accordion feature which allows us to increase the amount of the credit facility from $450 million to $600 million, subject to lenders' approval. Under the terms of the credit agreement, we pay a variable rate of interest and a commitment fee based on our leverage ratio. The credit agreement is for general corporate purposes, to meet our seasonal working capital requirements and repurchase our common stock. As of January 2, 2021, the weighted-average interest rate on borrowings under the credit facility was 1.5% and we were in compliance with all financial covenants.
We have an agreement with Synchrony Bank to offer qualified customers revolving credit arrangements to finance purchases from us (Synchrony Agreement). The Synchrony Agreement contains certain financial covenants, including a maximum leverage ratio and a minimum interest coverage ratio consistent with our Credit Agreement. As of January 2, 2021, we were in compliance with all financial covenants.
Under the terms of the Synchrony Agreement, Synchrony Bank sets the minimum acceptable credit ratings, the interest rates, fees and all other terms and conditions of the customers’ accounts, including collection policies and procedures, and is the owner of the accounts. As the accounts are owned by Synchrony Bank, at no time are the accounts purchased or acquired from us. We are not liable to Synchrony Bank for our customers’ credit defaults.
Critical Accounting Policies and Estimates
Our consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP). In connection with the preparation of our financial statements, we are required to make estimates and assumptions about future events and apply judgments that affect the reported amounts of assets, liabilities, sales, expenses and the related disclosures. Predicting future events is inherently an imprecise activity and as such requires the use of judgment. We base our assumptions, estimates and judgments on historical experience, current trends and other factors that management believes to be relevant at the time our consolidated financial statements are prepared. On a regular basis, management reviews the accounting policies, assumptions, estimates and judgments to ensure that our financial statements are presented fairly and in accordance with GAAP. However, because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates, and such differences could be material.
Our significant accounting policies are discussed in Note 1, Business and Summary of Significant Accounting Policies, of the Notes to Consolidated Financial Statements, which are included in Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K. Management believes the accounting policies discussed below are the most critical because they require management’s most difficult, subjective or complex judgments, resulting from the need to make estimates about the effect of matters that are inherently uncertain. Management has reviewed these critical accounting policies and estimates, and related disclosures with the Audit Committee of our Board.

Our critical accounting policies and estimates relate to stock-based compensation, warranty liabilities and revenue recognition.

Description |  | Judgments and Uncertainties |  | Effect if Actual Results Differ from Assumptions
Stock-Based Compensation |  |  |  |
We have stock-based compensation plans, which include non-qualified stock options and stock awards. See Note 1, Business and Summary of Significant Accounting Policies, and Note 8, Shareholders’ Deficit, to the Notes to Consolidated Financial Statements, included in Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K, for a complete discussion of our stock-based compensation programs. |  | Option-pricing models and generally accepted valuation techniques require management to make assumptions and to apply judgment to determine the fair value of our awards. These assumptions and judgments include estimating the volatility of our stock price, future employee forfeiture rates and future employee stock option exercise behaviors. Changes in these assumptions can materially affect the fair value estimates or future earnings adjustments. Performance-based stock awards require management to make assumptions regarding the likelihood of achieving performance targets. |  | We do not believe there is a reasonable likelihood that there will be a material change in the future estimates or assumptions we use to determine stock-based compensation expense. However, if actual results are not consistent with our estimates or assumptions, we may be exposed to changes in stock-based compensation expense that could be material. In addition, if actual results are not consistent with the assumptions used, the stock-based compensation expense reported in our financial statements may not be representative of the actual economic cost of the stock-based compensation. Finally, if the actual forfeiture rates, or the actual achievement of performance targets, are not consistent with the assumptions used, we could experience future earnings adjustments. A 10% change in our stock-based compensation expense for the year ended January 2, 2021, would have affected net income by approximately $1.7 million in 2020.
Warranty Liabilities |  |  |  |
We provide a limited warranty on most of the products we sell. See Note 1, Business and Summary of Significant Accounting Policies, to the Notes to Consolidated Financial Statements, included in Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K, for a complete discussion of our warranty program and liabilities. |  | The majority of our warranty claims are incurred within the first year. However, our warranty liability contains uncertainties because our warranty obligations cover an extended period of time. A revision of estimated claim rates or the projected cost of materials and freight associated with sending replacement parts to customers could have a material adverse effect on future results of operations. |  | We have not made any material changes in our warranty liability assessment methodology during the past three fiscal years. We do not believe there is a reasonable likelihood that there will be a material change in the estimates or assumptions we use to calculate our warranty liability. However, if actual results are not consistent with our estimates or assumptions, we may be exposed to losses or gains that could be material. A 10% change in our warranty liability at January 2, 2021, would have affected net income by approximately $0.9 million in 2020.

Table of Contents

Description |  | Judgments and Uncertainties |  | Effect if Actual Results Differ from Assumptions
Revenue Recognition |  |  |  |
Certain accounting estimates relating to revenue recognition contain uncertainty because they require management to make assumptions and to apply judgment regarding the effects of future events. See Note 1, Business and Summary of Significant Accounting Policies, and Note 9, Revenue Recognition, to the Notes to Consolidated Financial Statements, included in Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K, for a complete discussion of our revenue recognition policies. |  | Our estimates of sales returns contain uncertainties as actual sales return rates may vary from expected rates, resulting in adjustments to net sales in future periods. These adjustments could have an adverse effect on future results of operations. |  | We have not made any material changes in the accounting methodology used to establish our sales returns allowance during the past three fiscal years. We do not believe there is a reasonable likelihood that there will be a material change in the estimates or assumptions we use to calculate our sales returns allowance. However, if actual results are not consistent with our estimates or assumptions, we may be exposed to additional losses or gains in future periods. A 10% change in our sales returns allowance at January 2, 2021 would have affected net income by approximately $1.9 million in 2020.

Recent Accounting Pronouncements
See “Part II, Item 8. Financial Statements and Supplementary Data – Notes to Consolidated Financial Statements – Note 1, Business and Summary of Significant Accounting Policies - New Accounting Pronouncements” for recent accounting pronouncements that may affect our financial reporting.
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
We are exposed to changes in market-based short-term interest rates that will impact our net interest expense. If overall interest rates were one percentage point higher than current rates, our annual net income would decrease by $1.9 million based on the $244 million of borrowings under our credit facility at January 2, 2021. We do not manage our interest-rate volatility risk through the use of derivative instruments.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Shareholders of
Sleep Number Corporation
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Sleep Number Corporation and subsidiaries (the “Company”) as of January 2, 2021, and December 28, 2019, and the related consolidated statements of income, shareholders’ equity, and cash flows, for each of the three years in the period ended January 2, 2021, and the related notes and the schedule listed in the Index at Item 15 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of January 2, 2021, and December 28, 2019, and the results of its operations and its cash flows for each of the three years in the period ended January 2, 2021, in conformity with accounting principles generally accepted in the United States of America.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of January 2, 2021, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 2, 2021, expressed an unqualified opinion on the Company’s internal control over financial reporting.
Change in Accounting Principle
As discussed in Note 1 to the financial statements, the Company changed its method of accounting for leases in the year ended December 28, 2019, due to the adoption of ASU No. 2016-02 Leases (Topic 842) using the modified retrospective approach.
Basis for Opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the US federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Warranty Liability - Refer to Note 1 to the financial statements
Critical Audit Matter Description
The Company provides a limited warranty on most products sold. The estimated warranty liabilities, which are expensed at the time of sale and included in cost of sales, are based on historical trends and warranty claim rates incurred and the assumptions are adjusted for any current trends as appropriate. As of January 2, 2021, the Company has warranty liability of $12.2 million.
We identified the warranty liability as a critical audit matter because of the significant judgments made by management to estimate warranty claim rates. This required a high degree of auditor judgment and an increased extent of effort when performing audit procedures to evaluate the reasonableness of management’s estimates of future warranty claims based on historical claims paid, specifically due to a relatively short history of warranty claims paid for the Sleep Number 360 Smart Bed line from which to develop warranty liability estimates.
How the Critical Audit Matter Was Addressed in the Audit
Our procedures related to the warranty liabilities included the following, among others:
•We tested the effectiveness of controls related to warranty liabilities, including those over historical warranty claim data and estimated future warranty claim rates.
•We evaluated the reasonableness of management’s estimate of warranty liabilities by comparing the historical warranty claim trends to the current warranty claim rates of the Sleep Number 360 Smart Bed line and other products.
•We evaluated the completeness of the warranty liabilities through inquiries of operational and executive management regarding knowledge of known product warranty claims or product issues and evaluated whether they were appropriately considered in the determination of the warranty liabilities.
•We evaluated the methods and assumptions used by management to estimate the warranty liabilities by:
–Testing the underlying data that served as the basis for the estimate, to test that the inputs to the estimate were reasonable and to test the mathematical accuracy of the calculation.
–Developing an expectation of warranty liabilities and comparing it to the recorded balance.
–Comparing management’s prior-year assumption of expected claim rates to actuals incurred during the year to evaluate management’s ability to estimate the warranty liabilities.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Shareholders of
Sleep Number Corporation
Opinion on Internal Control over Financial Reporting
We have audited the internal control over financial reporting of Sleep Number Corporation and subsidiaries as of January 2, 2021, based on the criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of January 2, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements and financial statement schedule as of and for the year ended January 2, 2021, of the Company and our report dated March 2, 2021 expressed an unqualified opinion on those financial statements and financial statement schedule.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

SLEEP NUMBER CORPORATION
AND SUBSIDIARIES
Notes to Consolidated Financial Statements
(1) Business and Summary of Significant Accounting Policies
Business & Basis of Presentation
Sleep Number Corporation and our 100%-owned subsidiaries (Sleep Number or the Company) have a vertically integrated business model and are the exclusive designer, manufacturer, marketer, retailer and servicer of Sleep Number beds which allows us to offer consumers high-quality, individualized sleep solutions and services. Sleep Number also offers FlextFit adjustable bases, and Sleep Number pillows, sheets and other bedding products.
We generate revenue by marketing our innovations to new and existing customers, and selling products through Total Retail and
Wholesale/Other. Total Retail, which includes Stores, Online, Phone and Chat, sells directly to consumers. Wholesale/Other sells to
and through selected wholesale customers in the United States.
The consolidated financial statements include the accounts of Sleep Number Corporation and our subsidiaries. All significant intra-entity balances and transactions have been eliminated in consolidation.
Fiscal Year
Our fiscal year ends on the Saturday closest to December 31. Fiscal years and their respective fiscal year ends were as follows: fiscal 2020 ended January 2, 2021; fiscal 2019 ended December 28, 2019; and fiscal 2018 ended December 29, 2018. Fiscal 2020 had 53 weeks, 2019 and 2018 each had 52 weeks.
Use of Estimates in the Preparation of Financial Statements
The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires us to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of sales, expenses and income taxes during the reporting period. Predicting future events is inherently an imprecise activity and, as such, requires the use of judgment. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in these estimates will be reflected in the financial statements in future periods. Additionally, based on the duration and severity of the current global situation involving the novel coronavirus (COVID-19) pandemic, including but not limited to general economic conditions, consumer confidence, store closings mandated by federal, state or local authorities and possible supply chain disruptions, the extent to which COVID-19 will impact our business and our consolidated financial results will depend on future developments, which are highly uncertain and cannot be predicted.
Our critical accounting policies consist of stock-based compensation, warranty liabilities and revenue recognition.
Cash and Cash Equivalents
Cash and cash equivalents include highly-liquid investments with original maturities of three months or less. The carrying value of these investments approximates fair value due to their short-term maturity. Our banking arrangements allow us to fund outstanding checks when presented to the financial institution for payment, resulting in book overdrafts. Book overdrafts are included in accounts payable in our consolidated balance sheets and in net increase in short-term borrowings in the financing activities section of our consolidated statements of cash flows. Book overdrafts totaled $8 million and $33 million at January 2, 2021 and December 28, 2019, respectively.
Accounts Receivable
Accounts receivable are recorded net of an allowance for expected credit losses and consist primarily of receivables from third-party financiers for customer credit card purchases. The allowance is recognized in an amount equal to anticipated future write-offs. We estimate future write-offs based on delinquencies, aging trends, industry risk trends, our historical experience and current trends. Account balances are charged off against the allowance when we believe it is probable the receivable will not be recovered.

Inventories
Inventories include materials, labor and overhead and are stated at the lower of cost or net realizable value. Cost is determined by the first-in, first-out method. We review inventory quantities on hand and record reserves for obsolescence based on historical selling prices, current market conditions and forecasted product demand, to reduce inventory to net realizable value.
Property and Equipment
Property and equipment, carried at cost, is depreciated using the straight-line method over the estimated useful lives of the assets. The cost and related accumulated depreciation of assets sold or retired is removed from the accounts with any resulting gain or loss included in net income in our consolidated statements of operations. Maintenance and repairs are charged to expense as incurred. Major renewals and betterments that extend useful life are capitalized.
Leasehold improvements are depreciated over the shorter of the estimated useful lives of the assets or the contractual term of the lease, with consideration of lease renewal options if renewal appears probable.
Estimated useful lives of our property and equipment by major asset category are as follows:

Leasehold improvements | 5 to 15 years
Furniture and equipment | 3 to 15 years
Production machinery | 3 to 7 years
Computer equipment and software | 3 to 12 years

Goodwill and Intangible Assets, Net
Goodwill is the difference between the purchase price of a company and the fair market value of the acquired company’s net identifiable assets. Our intangible assets include developed technologies and trade names/trademarks. Definite-lived intangible assets are being amortized using the straight-line method over their estimated lives, ranging from 8-10 years.
Asset Impairment Charges
Long-lived Assets and Definite-lived Intangible Assets - we review our long-lived assets and definite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When evaluating long-lived assets for potential impairment, we first compare the carrying value of the asset to the estimated future cash flows (undiscounted and without interest charges - plus proceeds expected from disposition, if any). If the estimated undiscounted cash flows are less than the carrying value of the asset, we calculate an impairment loss. The impairment loss calculation compares the carrying value of the asset to the asset’s estimated fair value. When we recognize an impairment loss, the carrying amount of the asset is reduced to estimated fair value based on discounted cash flows, quoted market prices or other valuation techniques. Assets to be disposed of are reported at the lower of the carrying amount of the asset or fair value less costs to sell. We review retail store assets for potential impairment based on historical cash flows, lease termination provisions and expected future retail store operating results. If we recognize an impairment loss for a depreciable long-lived asset, the adjusted carrying amount of the asset becomes its new cost basis and will be depreciated (amortized) over the remaining useful life of that asset.
Goodwill and Indefinite-lived Intangible Assets - goodwill and indefinite-lived intangible assets are not amortized but are tested for impairment annually or when there are indicators of impairment using a fair value approach. The Financial Accounting Standards Board’s (FASB) guidance allows us to perform either a quantitative assessment or a qualitative assessment before calculating the fair value of a reporting unit. We have elected to perform the quantitative assessment. The quantitative goodwill impairment test is a two-step process. The first step is a comparison of the fair value of the reporting unit with its carrying amount, including goodwill. If this step reflects impairment, then the loss would be measured as the excess of recorded goodwill over its implied fair value. Implied fair value is the excess of fair value of the reporting unit over the fair value of all identified assets and liabilities. Fair value is determined using a market-based approach utilizing widely accepted valuation techniques, including quoted market prices and our market capitalization. Indefinite-lived intangible assets are assessed for impairment by comparing the carrying value of an asset with its fair value. If the carrying value exceeds fair value, an impairment loss is recognized in an amount equal to the excess. Based on our 2020 assessments, we determined there was no impairment.

Warranty Liabilities
We provide a limited warranty on most of the products we sell. The estimated warranty costs, which are expensed at the time of sale and included in cost of sales, are based on historical trends and warranty claim rates incurred by us and are adjusted for any current trends as appropriate. The majority of our warranty claims are incurred within the first year. Our warranty liability contains uncertainties because our warranty obligations cover an extended period of time and require management to make estimates for claim rates and the projected cost of materials and freight associated with sending replacement parts to customers. We regularly assess and adjust the estimate of accrued warranty claims by updating claims rates for actual trends and projected claim costs.
We classify as non-current those estimated warranty costs expected to be paid out in greater than one year. The activity in the accrued warranty liabilities account was as follows (in thousands):

| 2020 |  | 2019 |  | 2018
Balance at beginning of period | $ | 11,345 |  |  | $ | 10,389 |  |  | $ | 9,320 |
Additions charged to costs and expenses for current-year sales | 13,387 |  |  | 10,949 |  |  | 12,385 |
Deductions from reserves | (12,158) |  |  | (11,007) |  |  | (11,743) |
Change in liabilities for pre-existing warranties during the current year, including expirations | (422) |  |  | 1,014 |  |  | 427 |
Balance at end of period | $ | 12,152 |  |  | $ | 11,345 |  |  | $ | 10,389 |

Fair Value Measurements
Fair value measurements are reported in one of three levels based on the lowest level of significant input used:
•Level 1 – observable inputs such as quoted prices in active markets;
•Level 2 – inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and
•Level 3 – unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.
We generally estimate fair value of long-lived assets, including our retail stores, using the income approach, which we base on estimated future cash flows (discounted and with interest charges). The inputs used to determine fair value relate primarily to future assumptions regarding sales volumes, gross profit rates, retail store operating expenses and applicable probability weightings regarding future alternative uses. These inputs are categorized as Level 3 inputs under the fair value measurements guidance. The inputs used represent management’s assumptions about what information market participants would use in pricing the assets and are based upon the best information available at the balance sheet date.
Shareholders’ Deficit
Dividends
We are not restricted from paying cash dividends under our Credit Agreement so long as we are not in default under the Credit Agreement, our leverage ratio (as defined in our Credit Agreement) after giving effect to such restricted payments (as defined in our Credit Agreement) would not exceed 3.75:1.00 and no default or event of default (as defined in our Credit Agreement) would result therefrom. However, we have not historically paid, and have no current plans to pay, cash dividends on our common stock.
Share Repurchases
At January 2, 2021, we had $247 million remaining authorization under our $500 million board-approved share repurchase program. There is no expiration date governing the period over which we can repurchase shares. Any repurchased shares are constructively retired and returned to an unissued status. The cost of stock repurchases is first charged to additional paid-in-capital. Once additional paid-in capital is reduced to zero, any additional amounts are charged to accumulated deficit.

Revenue Recognition
We recognize revenue when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Revenue recognized excludes sales taxes. Amounts billed to customers for delivery and setup are included in net sales. For most products, we receive payment before or promptly after, the products or services are delivered to the customer.
We accept sales returns of most products during a 100-night trial period. Accrued sales returns represent a refund liability for the amount of consideration that we do not expect to be entitled to because it will be refunded to customers. The refund liability estimate is based on historical return rates and is adjusted for any current trends as appropriate. Each reporting period we remeasure the liability to reflect changes in the estimate, with a corresponding adjustment to net sales.
Our beds sold with SleepIQ technology contain multiple performance obligations including the bed, and SleepIQ hardware and software. We analyze our multiple performance obligation(s) to determine whether they are distinct and can be separated or whether they must be accounted for as a single performance obligation. We determined that the beds sold with the SleepIQ technology have two performance obligations consisting of: (i) the bed; and (ii) SleepIQ hardware and software. SleepIQ hardware and software are not separable as the hardware and related software are not sold separately and the software is integral to the hardware’s functionality. We determine the transaction price for multiple performance obligations based on their relative standalone selling prices. The performance obligation related to the bed is satisfied at a point in time. The performance obligation related to SleepIQ technology is satisfied over time based on the ongoing access and usage by the customer of software essential to the functionality of SleepIQ technology. The deferred revenue and costs related to SleepIQ technology are recognized on a straight-line basis over the product’s estimated life of four years because our inputs are generally expended evenly throughout the performance period.
See Note 9, Revenue Recognition, for additional information on revenue recognition and sales returns.
Cost of Sales, Sales and Marketing, General and Administrative (G&A) and Research & Development (R&D) Expenses
The following tables summarize the primary costs classified in each major expense category (the classification of which may vary within our industry):

| Cost of Sales |  |  | Sales & Marketing

Leases
We determine if an arrangement is a lease at inception. Right-of-use (ROU) assets and operating lease liabilities are recognized at the lease commencement date based on the estimated present value of future lease payments over the lease term. We elected the option to not separate lease and non-lease components for all of our leases. Most of our leases do not provide an implicit interest rate nor is the rate available to us from our lessors. As an alternative, we use our estimated incremental borrowing rate, which is derived from information available at the lease commencement date, including publicly available data, in determining the present value of lease payments. Leases with an initial term of 12 months or less are not recorded on the balance sheet as an ROU asset or operating lease liability. We recognize operating lease costs for these short-term leases, primarily small equipment leases, on a straight-line basis over the lease term. At January 2, 2021, our finance ROU assets and associated lease liabilities were not significant.
See Note 1, Business and Summary of Significant Accounting Policies, New Accounting Pronouncements, Recently Adopted Accounting Guidance, below, and Note 7, Leases, for further information on our recent adoption of Financial Accounting Standards Board (FASB) Staff Q&A, Topic 840 and 842: Accounting for Lease Concessions Related to the Effects of the COVID-19 Pandemic.
Leases in fiscal 2018 were accounted for under ASC 840, Leases. Rent expense in fiscal 2018 was as follows (in thousands):

| 2018
Facility Rents: |
Minimum rents | $ | 71,851 |
Contingent rents | 1,847 |
Total | $ | 73,698 |
Equipment Rents | $ | 5,692 |

Pre-Opening Costs
Costs associated with the start-up and promotion of new retail store openings are expensed as incurred.
Advertising Costs
We incur advertising costs associated with print, digital and broadcast advertisements. Advertising costs are charged to expense when the ad first runs. Advertising expense was $253 million, $242 million and $210 million in 2020, 2019 and 2018, respectively. Advertising costs deferred and included in prepaid expenses in our consolidated balance sheet were not significant at January 2, 2021 and December 28, 2019, respectively.
Insurance
We are self-insured for certain losses related to health and workers’ compensation claims, although we obtain third-party insurance coverage to limit exposure to these claims. We estimate our self-insured liabilities using a number of factors including historical claims experience and analysis of incurred but not reported claims. Our self-insurance liability was $11 million and $9 million at January 2, 2021 and December 28, 2019, respectively. At January 2, 2021 and December 28, 2019, $7 million and $6 million, respectively, were included in current liabilities: compensation and benefits in our consolidated balance sheets and $4 million and $3 million, respectively, were included in other non-current liabilities in our consolidated balance sheets.
Software Capitalization
For software developed or obtained for internal use, we capitalize direct external costs associated with developing or obtaining internal-use software. In addition, we capitalize certain payroll and payroll-related costs for employees who are directly involved with the development of such applications. Capitalized costs related to internal-use software under development are treated as construction-in-progress until the program, feature or functionality is ready for its intended use, at which time depreciation commences. We expense any data conversion or training costs as incurred. Capitalized software costs are included in property and equipment, net in our consolidated balance sheet.
49

SLEEP NUMBER CORPORATION
AND SUBSIDIARIES
Notes to Consolidated Financial Statements - (continued)
We capitalize costs incurred with the implementation of a cloud computing arrangement that is a service contract, consistent with our policy for software developed or obtained for internal use. The capitalized implementation costs of cloud computing arrangements are expensed over the term of the cloud computing arrangement in the same line item in the statement of operations as the associated hosting fees. Capitalized costs incurred with the implementation of a cloud computing arrangement are included in prepaid expenses and other non-current assets in our consolidated balance sheet, and in operating cash flows in our consolidated statement of cash flows.
Stock-Based Compensation
We compensate officers, directors and key employees with stock-based compensation under stock plans approved by our shareholders and administered under the supervision of our Board of Directors (Board). At January 2, 2021, a total of 2.4 million shares were available for future grant. These plans include non-qualified stock options and stock awards.
We record stock-based compensation expense based on the award’s fair value at the grant date and the awards that are expected to vest. We recognize stock-based compensation expense over the period during which an employee is required to provide services in exchange for the award. We reduce compensation expense by estimated forfeitures. Forfeitures are estimated using historical experience and projected employee turnover. We include, as part of cash flows from operating activities, the benefit of tax deductions in excess of recognized stock-based compensation expense. In addition, excess tax benefits or deficiencies are recorded as discrete adjustments to income tax expense.
Stock Options - stock option awards are granted at exercise prices equal to the closing price of our stock on the grant date. Generally, options vest proportionally over three years and expire after 10 years. Compensation expense is recognized ratably over the vesting period.
We determine the fair value of stock options granted and the resulting compensation expense at the date-of-grant using the Black-Scholes-Merton option-pricing model. Descriptions of significant assumptions used to estimate the expected volatility, risk-free interest rate and expected term are as follows:
Expected Volatility – expected volatility was determined based on implied volatility of our traded options and historical volatility of our stock price.
Risk-Free Interest Rate – the risk-free interest rate was based on the implied yield available on U.S. Treasury zero-coupon issues at the date of grant with a term equal to the expected term.
Expected Term – expected term represents the period that our stock-based awards are expected to be outstanding and was determined based on historical experience and anticipated future exercise patterns, giving consideration to the contractual terms of unexercised stock-based awards.
Stock Awards - we issue stock awards to certain employees in conjunction with our stock-based compensation plan. The stock awards generally vest over three years based on continued employment (time-based). Compensation expense related to stock awards, except for stock awards with a market condition, is determined on the grant date based on the publicly quoted closing price of our common stock and is charged to earnings on a straight-line basis over the vesting period. Stock awards with a market condition are valued using a Monte Carlo simulation model. The significant assumptions used to estimate the expected volatility and risk-free interest rate are similar to those described above in Stock Options.
In April 2020, we took actions to maintain liquidity and cut costs in response to the COVID-19 pandemic, including offering a salary for stock program. Under that program, certain employees elected to forego a percentage of their cash salary for the remainder of the year in exchange for time-based stock awards that represented the value of the cash salary foregone. Subject to continuing employment, these awards vested in December 2020.
Certain time-based stock awards have a performance condition (performance-based). The final number of shares earned for performance-based stock awards and the related compensation expense is adjusted up or down to the extent the performance target is met. The actual number of shares that will ultimately be awarded range from 0% - 200% of the targeted amount for the 2020, 2019 and 2018 awards. We evaluate the likelihood of meeting the performance targets at each reporting period and adjust compensation expense, on a cumulative basis, based on the expected achievement of each of the performance targets. For performance-based stock awards granted in 2020, 2019 and 2018, the performance targets are based on growth in net sales and in operating profit, and the performance periods are fiscal 2020 through 2022, 2019 through 2021, and fiscal 2018 through 2020, respectively.

See Note 8, Shareholders’ Deficit, for additional information on stock-based compensation.
Income Taxes
We recognize deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is established for any portion of deferred tax assets that are not considered more likely than not to be realized. We evaluate all available positive and negative evidence, including our forecast of future taxable income, to assess the need for a valuation allowance on our deferred tax assets.
We record a liability for unrecognized tax benefits from uncertain tax positions taken, or expected to be taken, in our tax returns. We follow a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. We consider many factors when evaluating and estimating our tax positions and tax benefits, which may require periodic adjustments, and may not accurately forecast actual outcomes.
We classify net interest and penalties related to income taxes as a component of income tax expense in our consolidated statements of operations.
Net Income Per Share
We calculate basic net income per share by dividing net income by the weighted-average number of common shares outstanding during the period. We calculate diluted net income per share based on the weighted-average number of common shares outstanding adjusted by the number of potentially dilutive common shares as determined by the treasury stock method. Potentially dilutive shares consist of stock options and stock awards.
Sources of Supply
We currently obtain materials and components used to produce our beds from outside sources. As a result, we are dependent upon suppliers that in some instances, are our sole source of supply, or supply the vast majority of the particular component or material. We continuously evaluate opportunities to dual-source key components and materials. The failure of one or more of our suppliers to provide us with materials or components on a timely basis could significantly impact our consolidated results of operations and net income per share. While we believe that these materials and components, or suitable replacements, could be obtained from other sources in the event of a disruption or loss of supply, we may not be able to find alternative sources of supply or alternative sources of supply on comparable terms and an unexpected loss of supply over a short period of time may not allow us to replace these sources in the ordinary course of business.
Recently Adopted Accounting Guidance
New Accounting Pronouncements
In April 2020, the FASB issued a Staff Q&A, Topic 840 and 842: Accounting For Lease Concessions Related to the Effects of the COVID-19 Pandemic. To provide clarity in response to the COVID-19 pandemic crisis, the FASB staff believes that it would be acceptable for entities to make an election to account for lease concessions related to the effects of the COVID-19 pandemic consistent with how those concessions would be accounted for under Topic 842 as though enforceable rights and obligations for those concessions existed (regardless of whether those enforceable rights and obligations for the concessions explicitly exist in the contract).
Consequently, for concessions related to the effects of the COVID-19 pandemic, we are not required to analyze each contract to determine whether enforceable rights and obligations for concessions exist in the contract and can elect to apply or not apply the lease modification guidance in Topic 842 to those contracts. This election is available for concessions related to the effects of the COVID-19 pandemic that do not result in a substantial increase in the rights of the lessor or our obligations as the lessee. For example,
51

AND SUBSIDIARIES
Notes to Consolidated Financial Statements - (continued)
this election is available for concessions that result in the total payments required by the modified contract being substantially the same as or less than total payments required by the original contract. The FASB staff expects that reasonable judgment will be exercised in making those determinations. Some concessions will provide a deferral of payments with no substantive changes to the consideration in the original contract. A deferral affects the timing, but the amount of the consideration is substantially the same as that required by the original contract. The staff expects that there will be multiple ways to account for those deferrals, none of which the staff believes are more preferable than the others. Two of those methods are:
a.Account for the concessions as if no changes to the lease contract were made. Under that accounting, a lessor would increase its lease receivable, and a lessee would increase its accounts payable as receivables/payments accrue. In its income statement, a lessor would continue to recognize income, and a lessee would continue to recognize expense during the deferral period.
b.Account for the deferred payments as variable lease payments.
We adopted option a. above and continue to recognize rent expense on a straight-line basis. At January 2, 2021, we had deferred cash rent payments of $3.1 million. See Note 7, Leases, for further information.
(2) Fair Value Measurements
At January 2, 2021 and December 28, 2019, we had $12 million and $8 million, respectively, of debt and equity securities that fund our deferred compensation plan and are classified in other non-current assets. We also had corresponding deferred compensation plan liabilities of $12 million and $8 million at January 2, 2021 and December 28, 2019, respectively, which are included in other non-current liabilities. The majority of the debt and equity securities are Level 1 as they trade with sufficient frequency and volume to enable us to obtain pricing information on an ongoing basis. Unrealized gains/(losses) on the debt and equity securities offset those associated with the corresponding deferred compensation plan liabilities.

(6) Credit Agreement
As of January 2, 2021, our credit facility had a total commitment amount of $450 million. The credit facility is for general corporate purposes, to meet our seasonal working capital requirements and to repurchase our stock. The credit agreement includes an accordion feature which allows us to increase the amount of the credit facility from $450 million to $600 million, subject to lenders’ approval. The credit agreement provides the lenders with a collateral security interest in substantially all of our assets and those of our subsidiaries and requires us to comply with, among other things, a maximum leverage ratio (4.5x) and a minimum interest coverage ratio (3.0x). Under the terms of the credit agreement, we pay a variable rate of interest and a commitment fee based on our leverage ratio. The credit agreement matures in February 2024. We were in compliance with all financial covenants as of January 2, 2021.
The following tables summarizes our borrowings under the credit facility ($ in thousands):

| January 2, 2021 |  | December 28, 2019

(7) Leases
We lease our retail, office and manufacturing space under operating leases which, in addition to the minimum lease payments, may require payment of a proportionate share of the real estate taxes and certain building operating expenses. While our local market development approach generally results in long-term participation in given markets, our retail store leases generally provide for an initial lease term of five to 10 years. Our office and manufacturing leases provide for an initial lease term of up to 15 years. In addition, our mall-based retail store leases may require payment of variable rent based on net sales in excess of certain thresholds. Certain leases may contain options to extend the term of the original lease. The exercise of lease renewal options is at our sole discretion. Lease options are included in the lease term only if exercise is reasonably certain at lease commencement. Our lease agreements do not contain any material residual value guarantees. We also lease vehicles and certain equipment under operating leases with an initial lease term of three to five years.
Our operating lease costs include facility, vehicle and equipment lease costs, but exclude variable lease costs. Operating lease costs are recognized on a straight-line basis over the lease term, after consideration of rent escalations and rent holidays. The lease term for purposes of the calculation begins on the earlier of the lease commencement date or the date we take possession of the property. During lease renewal negotiations that extend beyond the original lease term, we estimate straight-line rent expense based on current market conditions. Variable lease costs are recorded when it is probable the cost has been incurred and the amount can be reasonably estimated. Future payments for real estate taxes and certain building operating expenses for which we are obligated are not included in operating lease costs.
At January 2, 2021, our finance right-of-use assets and lease liabilities were not significant.
Lease costs were as follows (in thousands):

On December 22, 2017, the Tax Cuts and Jobs Act (TCJA) was enacted. The TCJA reduced the statutory federal tax rate from 35% to 21% starting in 2018. In addition, there were various other tax law changes that impacted us. In connection with the reduction of the federal tax rate, we recognized a provisional tax benefit of $1.7 million for the year ended December 30, 2017. This provisional tax benefit was related to the re-measurement of U.S. deferred tax assets and liabilities using a federal tax rate of 21%, which, under the TCJA, is expected to be in place when such deferred assets and liabilities reverse in future periods. During 2018, we updated our provisional tax benefit based on new information, including a tax planning analysis, and recorded an additional $2.9 million tax benefit.

At January 2, 2021, we had net operating loss carryforwards for federal purposes of $0.6 million, which will expire between 2025 and 2027.
We evaluate our deferred income taxes quarterly to determine if valuation allowances are required. As part of this evaluation, we assess whether valuation allowances should be established for any deferred tax assets that are not considered more likely than not to be realized, using all available evidence, both positive and negative. This assessment considers, among other matters, the nature, frequency, and severity of historical losses, forecasts of future profitability, taxable income in available carryback periods and tax planning strategies. In making such judgments, significant weight is given to evidence that can be objectively verified. We have provided a $0.6 million valuation allowance resulting primarily from our inability to utilize certain foreign net operating losses, and federal net operating losses associated with our 2015 acquisition of BAM Labs, Inc.

Unrecognized Tax Benefits
Reconciliations of the beginning and ending amounts of unrecognized tax benefits were as follows (in thousands):

At both January 2, 2021 and December 28, 2019, we had $3 million of unrecognized tax benefits, which if recognized, would affect our effective tax rate. The amount of unrecognized tax benefits is not expected to change materially within the next 12 months.
(12) Commitments and Contingencies
Legal Proceedings
We are involved from time to time in various legal proceedings arising in the ordinary course of our business, including primarily commercial, product liability, employment and intellectual property claims. In accordance with U.S. generally accepted accounting principles, we record a liability in our consolidated financial statements with respect to any of these matters when it is both probable that a liability has been incurred and the amount of the liability can be reasonably estimated. If a material loss is reasonably possible but not known or probable, and may be reasonably estimated, the estimated loss or range of loss is disclosed. With respect to currently pending legal proceedings, we have not established an estimated range of reasonably possible material losses either because we believe that we have valid defenses to claims asserted against us, the proceeding has not advanced to a stage of discovery that would enable us to establish an estimate, or the potential loss is not material. We currently do not expect the outcome of pending legal proceedings to have a material effect on our consolidated results of operations, financial position or cash flows. Litigation, however, is inherently unpredictable, and it is possible that the ultimate outcome of one or more claims asserted against us could adversely impact our consolidated results of operations, financial position or cash flows. We expense legal costs as incurred.
On September 18, 2018, two former Home Delivery team members filed suit, now venued in San Diego County Superior Court, California, alleging representative claims on a purported class action basis under the California Labor Code Private Attorney General Act. While the two representative plaintiffs were in the Home Delivery workforce, the Complaint does not limit the purported plaintiff class to that group. The plaintiffs allege that Sleep Number failed or refused to adopt adequate practices, policies and procedures relating to wage payments, record keeping, employment disclosures, meal and rest breaks, among other claims, under California law. The Complaint sought damages in the form of civil penalties and plaintiffs’ attorneys’ fees. The parties have executed a settlement agreement, including the settlement and release of certain additional related claims that are contained in a consolidated complaint, which received final Court approval on January 8, 2021 and is proceeding through the final administrative and appeal processes.
On March 27, 2018, Level Sleep, LLC (Level Sleep) filed a patent infringement lawsuit against Sleep Number in the Federal District Court for the Eastern District of Texas. In its Complaint, Level Sleep claims that Sleep Number infringed two patents owned by Level Sleep, U.S. Patent Nos. 6,807,698 and 7,036,172 (the Patents), by, among other things, making, using, offering for sale, or selling within the United States, and/or importing into the United States, beds with sleep surfaces having foam with multiple zones in the longitudinal direction. Level Sleep has asserted that five non-360® beds no longer sold and two current non-360 beds infringe the Patents. Level Sleep seeks damages in the form of a reasonable royalty. Sleep Number has asserted that the Patents are invalid and that our products do not infringe the Patents. On January 14, 2020, the Court granted summary judgment in favor of Sleep Number, finding that Sleep Number’s products do not infringe the Patents. Level Sleep has filed an appeal of the Court’s summary judgment order, which is currently pending with the Federal Circuit Court of Appeals. We intend to continue vigorously defending this matter.

Consumer Credit Arrangements
We refer customers seeking extended financing to certain third-party financiers (Card Servicers). The Card Servicers, if credit is granted, establish the interest rates, fees, and all other terms and conditions of the customer’s account based on their evaluation of the creditworthiness of the customer. As the accounts are owned by the Card Servicers, at no time are the accounts purchased or acquired from us. We are not liable to the Card Servicers for our customers’ credit defaults.
Commitments
As of January 2, 2021, we had $53 million of inventory purchase commitments. As part of the normal course of business, there are a limited number of inventory supply contracts that contain penalty provisions for failure to purchase contracted quantities. We do not currently expect any payments under these provisions. At January 2, 2021, we had entered into 52 lease commitments primarily for future retail store locations. These lease commitments provide for total lease payments over the next three to 10 years, which if consummated based on current cost estimates, would approximate $87 million over the initial lease term. The future lease payments for these lease commitments have been excluded in the total operating lease payments in Note 7, Leases.
13. COVID-19 Pandemic
At the onset of the COVID-19 pandemic in mid-March, government restrictions resulted in the temporary closure of most of our retail stores. While prioritizing the safety of our team, serving our customers and ensuring business continuity, we swiftly took decisive actions to strengthen our liquidity, cash flows and financial position, and mitigate the future impact on our operations and financial performance.
In 2020, net sales increased 9% and net income increased by 70% compared with the same period one year ago, despite a 20% decline in net sales during the three months ended June 27, 2020 when 47% of our stores were closed on average. Approximately 99% of our stores were open on average during the six months ended January 2, 2021.
While we have generated strong financial performance during 2020, the volatility, length and severity of the pandemic's impact on consumer demand and the resulting impact on our future financial performance remains uncertain. See Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations and Part I: Item 1A. Risk Factors for
additional discussion on the COVID-19 pandemic and the impact on our business.

ITEM 9A. CONTROLS AND PROCEDURES
Conclusions Regarding the Effectiveness of Disclosure Controls and Procedures
We maintain disclosure controls and procedures, as defined in Exchange Act Rule 13a-15(e), that are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to the Company’s management, including its principal executive officer and principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this annual report. Based on this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this annual report.
Management’s Report on Internal Control Over Financial Reporting
Sleep Number’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). 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. Our internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our internal control over financial reporting based on the framework in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation under these criteria, management concluded that our internal control over financial reporting was effective as of January 2, 2021. The report of Deloitte & Touche LLP, our independent registered public accounting firm, regarding the effectiveness of our internal control over financial reporting is included in this report in “Part II, Item 8, Financial Statements and Supplementary Data” under “Report of Independent Registered Public Accounting Firm.”
Fourth Quarter Changes in Internal Control Over Financial Reporting
There were no changes in our internal control over financial reporting during the quarter ended January 2, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
