Item 1.  Business

Overview

PART I

Wayfair is one of the world's largest online destinations for the home. Through our e-commerce business model, we offer 

customers visually inspired browsing, compelling merchandising, easy product discovery and attractive prices for over ten 
million products from over 10,000 suppliers. 

We are focused on bringing our customers an experience that is at the forefront of shopping for the home online. Our 
primary target customer is a 35- to 65-year-old woman with an annual household income of $50,000 to $250,000, who we 
believe is underserved by traditional brick and mortar and other retailers of home goods. Because each of our customers has a 
different taste, style, purchasing goal, and budget when shopping for her home, we have built one of the largest online selections 
of furniture, décor, decorative accents, housewares, seasonal decor, and other home goods. We are able to offer this vast selection 
of products because we hold minimal inventory. We specialize in the home category and this has enabled us to build a shopping 
experience and logistics infrastructure that is tailored to the unique characteristics of our market.

The delivery experience and overall customer service we offer our shoppers are central to our business. The majority of our 

products are shipped to customers directly from our suppliers with an increasing proportion flowing through our own logistics 
network. We have invested considerably in our logistics network and increasingly leverage these capabilities to improve the 
experience for both customers and suppliers. This network is comprised of CastleGate and the Wayfair Delivery Network 
("WDN"). Our CastleGate facilities enable suppliers to forward-position their inventory in our warehouses, allowing us to offer 
faster delivery. Through WDN, we can directly manage large parcel deliveries via consolidation centers, cross docks and last 
mile delivery facilities, which, alongside CastleGate, enables us to speed up deliveries, reduce damage and decrease our reliance 
on third parties. We believe these investments in logistics capabilities result in an enhanced experience for our customers and 
suppliers. We also believe providing superior customer service is key to delighting our customers. Our customer service 
locations are staffed with approximately 2,000 highly-trained sales and service employees located in the United States ("U.S.") 
and Europe. 

Our co-founders are lifetime tech innovators who have worked together in the commercial Internet sector since 1995. As 

engineers themselves, they have created a company culture deeply rooted in technology and data. Their significant equity 
ownership in Wayfair has informed their leadership and allowed them to take a long-term view when building our company. 

The U.S. is currently our largest market, and we continue to scale our international business in Canada, the United 
Kingdom, and Germany by building our supplier networks, logistics infrastructure and brand presence in those countries.

Segments 

Our operating and reportable segments are U.S. and International. See Note 11 to the Consolidated Financial Statements, 

Segment and Geographic Information, included in Part II, Item 8, Financial Statements and Supplementary Data, of this Annual 
Report on Form 10-K. Net revenue of the U.S. segment represented 88% of consolidated net revenue for the year ended 
December 31, 2017.

Our Industry

The home goods market is large and characterized by specific consumer trends, structural challenges and market dynamics 

that are shaping the future of our industry.

Addressable Market Size and Growth

We believe the annual U.S. market for home goods is approximately $275 billion, of which approximately 10% is sold 

online. According to data released by the U.S. Census Bureau, there are approximately 67 million households in the U.S. with 
annual incomes between $50,000 and $250,000. Moreover, we believe there are approximately 70 million millennials (which we 
define as individuals currently between the ages of 22 to 35) in the U.S., many of whom are accustomed to purchasing goods 
online. As millennials age, start new families and move into new homes, we expect online sales of home goods to increase. In 
addition, we believe the online home goods market will further grow as older generations of consumers become increasingly 
comfortable purchasing online. With our presence in Canada and western Europe, we believe we have more than doubled the 
size of our total addressable market.

Why Home is Different

Home is shopped differently than other retail verticals. Homes are personal expressions of self and identity, which is why 

many consumers seek uniqueness, crave originality and enjoy the feeling created by home design, furniture and décor. 
Consumers shopping for home goods often cannot articulate exactly what they are looking for and they rarely know the names of 
the manufacturer brands they like, as the category is largely unbranded. We believe search-based websites  have difficulty 
serving customers shopping for home products in this more emotional, visual and inspirational manner.

When shopping for the home, consumers desire uniqueness, which requires vast selection. In the market for home goods, 

consumers with different tastes, styles, purchasing goals and budgets require a broad selection of products and choices. Brick 
and mortar home goods retailers must balance scale of selection with the challenges of high inventory carrying costs and limited 
showroom and storage space. To browse a vast selection of products across highly-fragmented brick and mortar retailers, 
consumers must shop multiple stores. We believe the lack of an easy-to-browse, one-stop shopping experience with massive 
selection has led to dissatisfaction with brick and mortar home goods shopping. 

Logistics, fulfillment and customer service for home goods products are challenging given the variety of categories and 

price points and the mix of heavy and bulky items. Home goods often have a low dollar value to weight ratio compared to other 
categories of retail, therefore requiring a logistics network that is optimized for items with those characteristics. Many consumers 
also seek first-rate customer service so they are not burdened with managing delivery, shipping and return logistics on their own. 
However, we believe big box retailers that serve the mass market for home goods are often unable or unwilling to provide this 
level of service. 

Our Solution - Key Benefits for Our Customers

We offer broad selection and choice. We have one of the largest online selections of furniture, décor, decorative accents, 
housewares, seasonal décor and other home goods with over ten million products from over 10,000 suppliers. We have built a 
portfolio of over 70 house brands, which offer a curated brand experience, making it easier for customers to discover styles, 
products and price points that appeal to them.

Convenience and value are central to our offering. We are a one-stop shop for consumers in the home goods category, with 

pricing designed to be on par with big box retailers and a merchandising experience designed to be on par with specialty 
retailers. For items shipped from our CastleGate warehouses, we are able to deliver many products to a majority of the U.S. 
population in 2 days or less.

We give customers inspirational content and an engaging shopping experience. To inspire customers, we produce beautiful 

imagery and highly-tailored editorial content both in house and through third parties. We use personalization to create a more 
engaging consumer experience, and we allow customers to create looks they love with tools such as our Idea Boards. More than 
half of the traffic coming to Wayfair.com is from mobile devices and our investment in mobile allows us to deliver value, 
convenience and inspiration to consumers anytime and anywhere. Our mobile app also offers customers a powerful way to shop 
for their home from their home using our "View in Room 3D" augmented reality tool. 

Superior customer service is a core part of the experience we offer shoppers. Our customer service organization has 
approximately 2,000 employees who help consumers navigate our sites, answer questions and complete orders. This team helps 
us build trust with consumers, build our brand awareness, enhance our reputation and drive sales.

Our Solution - Key Benefits for Our Suppliers

We give suppliers cost-effective access to our large customer base. We sell products from over 10,000 suppliers, many of 

which are small, family-run operations without well-known product brands and without easy retail access to a large customer 
base. We provide our suppliers with access to our customer base of 11.0 million active customers, enabling them to increase their 
sales and access the growing e-commerce market.

Suppliers can leverage our technological expertise to drive sales. Our technology platform is designed to allow suppliers to 
easily provide us with their full product selection. We offer our suppliers a view of our demand and inventory needs via powerful 
data and analytics. Through our technology platform, we believe many of our suppliers have increased their sales, which has 
strengthened their loyalty to us. 

Our logistics infrastructure allows us to ship directly to our customers from our suppliers or from our CastleGate 
warehouses. This fulfillment network is a key component of our custom-built and seamlessly integrated technology and 
operational platform.

Sites and Brands 

Each of our customers has a different taste, style, purchasing goal and budget when shopping for her home. To help her 

find the right products for her home, we offer five distinct sites, each with a unique brand identity that offers a tailored shopping 
experience and rich product selection to a different target audience.

Wayfair: an online destination for all things home

Joss & Main: where beautiful furniture and finds meet irresistible savings 

AllModern: your home for affordable modern design 

Birch Lane: a collection of classic furnishings and timeless home décor

Perigold: unparalleled access to the finest home décor and furnishing

Wayfair represents a significant majority of our revenue and is the only one of our sites that also operates internationally, 

operating as Wayfair.ca in Canada, Wayfair.co.uk in the United Kingdom and Wayfair.de in Germany.

On our sites, we also feature certain products under our house brands, such as Three PostsTM and Mercury RowTM. Through 
these house brands, we help our customers navigate our sites to find items quickly that match her particular style and price point. 

"Direct Retail" sales include net revenue generated through the five distinct sites described above. In additional to Direct 
Retail, we also generate "Other" net revenue through two sources, namely Retail Partners and Wayfair Media Solutions. Retail 
Partners net revenue is generated from sites operated by third parties. These relationships allow consumers to purchase Wayfair 
products through the retail partners' websites . We made the strategic decision starting in 2014 to deemphasize this part of our 
business. Wayfair Media Solutions is a smaller portion of our net revenue that is generated through third-party advertisers that 
pay for advertisements placed on our sites. Wayfair helps manufacturers, retailers and other advertisers market to our large 
consumer audience.

Technology

We have custom-built our proprietary technology and operational platform to deliver the best experience for both our 

customers and suppliers. Our success has been built on a culture of data-driven decision-making, operational discipline and an 
unwavering focus on the customer. We believe that control of our technology systems and the ability to update them often is a 
competitive advantage. 

Our team of over 1,300 engineers and data scientists has built a full set of technology solutions specific to the home goods 
market. Our storefront consists of a large set of tools and systems with which our customers directly interact, that are specifically 
tuned for shopping the home goods category by mixing lifestyle imagery with easy-to-use navigation tools and personalization 
features designed to increase customer conversion. We have designed operations software to deliver the reliable and consistent 
experience consumers desire, with proprietary software enhancing our performance in areas such as integration with our 
suppliers, our warehouse and logistics network and our customer service centers. Much of our advertising technology was 
internally developed, including campaign management and bidding algorithms for online advertising. This allows us to leverage 
our internal data and target customers efficiently across various channels. We also partner selectively with marketing partners 
where we find solutions that meet our marketing objectives and deliver strong return on investment. 

Much of the underlying infrastructure for storefront, operations and advertising technology is common across all of our 
sites and countries. Our systems are managed in geographically distributed, highly secure data centers that are engineered for 
high availability. These systems are monitored 24x7 by our network operations center for performance and security.

Marketing

Our marketing efforts bring new and repeat customers to our sites and help us acquire their email addresses through 
various paid and non-paid advertising methods. Our paid advertising efforts consist primarily of online channels, including 
search engine marketing, display advertising, and paid social media, and to a lesser extent direct mail and television 
advertisements. Our non-paid advertising efforts include search engine optimization, non-paid social media, mobile "push" 
notifications and email. Upon acquiring a customer or a potential customer's email address, we seek to increase their engagement 
with our sites and drive repeat purchases. This effort to increase engagement and repeat purchasing is driven by all of our 
marketing tools, including email marketing efforts and customer retargeting. We rigorously manage our paid marketing efforts 
towards the goal that each new spending initiative is cost-effective with a measurable return on investment within a short period 
of time.

Logistics

Our logistics network was built specifically for the home category, where items can be bulky, heavy and prone to damage. 

Historically, our primary method of fulfillment was a drop-ship network where integration into our suppliers' back-end 
technology infrastructure allowed us to process an order and send it directly to a supplier's warehouse. We would then arrange 
for shipment from the loading dock of the supplier's warehouse to the customer's home. Depending on the size of the package, 
the delivery would be made either through carriers such as FedEx, UPS, the U.S. Postal Service or third party line haul trucking 
companies and third party last mile home delivery agents. An increasing proportion of customer orders are being shipped from 
our CastleGate warehouses and delivered through our WDN, which includes consolidation centers, cross docks, and last mile 
delivery facilities. We believe that our proprietary logistics network will help drive incremental sales by delighting our customers 
with faster delivery times and a better home delivery experience. Over time we believe this network will also lower our costs per 
order by reducing damage rates and leveraging economies of scale in transportation.

Customer Service

Our customer service team consists of approximately 2,000 Wayfair sales and service consultants and employees located 

across the U.S. and Europe who are available to help our customers with sales and service via phone, email or online chat. 
Because we view superior customer service as one of our key values, our sales and service employees receive extensive training 
as well as competitive compensation and benefit packages. The team consists of generalists as well as specialists who have 
deeper expertise and training in select areas of our catalog, such as lighting, flooring and upholstery.

Our Growth Strategy

Our goal is to further improve our leadership in the home goods market by pursuing the following key strategies:

continue building our brands by delighting our customers; 

acquire new customers and increase repeat purchases from existing customers;

invest in technology to further improve our customer and supplier experiences;

grow certain categories where we under index the broader home goods market today, such as home improvement 
(e.g. plumbing, lighting and flooring), housewares, seasonal decor and decorative accents;

increase delivery speed and lower damage rates through the continued build-out of our proprietary logistics 
network;

continue to expand internationally; and

opportunistically pursue strategic acquisitions.

Competition

The market for online home goods and furniture is highly competitive, fragmented and rapidly changing. While we are 
primarily focused on the mass market, we compete across all segments of the home goods market. Our competition includes 
furniture stores, big box retailers, department stores, specialty retailers and online retailers and marketplaces in the U.S., Canada, 
the United Kingdom and Germany, including:

•  Furniture Stores: Ashley Furniture, Bob's Discount Furniture, Havertys, Raymour & Flanigan, Rooms To Go;

•  Big Box Retailers: Bed Bath & Beyond, Home Depot, IKEA, Lowe's, Target and Walmart;

•  Department Stores: JCPenney and Macy's;

• 

Specialty Retailers: Crate and Barrel, Ethan Allen, TJX, At Home, Williams Sonoma, Restoration Hardware, 
Arhaus, Horchow, Room & Board, Mitchell Gold + Bob Williams;

•  Online Retailers and Marketplaces: Amazon, Houzz and eBay; and

• 

International: Leon's, Canadian Tire, John Lewis, Argos, Otto and Home24, in addition to several of the 
companies listed above who also compete with us internationally.

We believe that the primary competitive factors in the mass market are vast selection, visually inspiring browsing, 
compelling merchandising, ease of product discovery, price, convenience, reliability, speed of fulfillment and customer service. 
We believe our technological and operational expertise allows us to provide our customers with a vast selection of goods, 

5

Table of Contents

attractive price points, reliable and timely fulfillment, plus superior customer service, and that the combination of these 
capabilities is what provides us with a sustainable competitive advantage.

Employees

As of December 31, 2017, we had 7,751 full-time equivalent employees. Additionally, we rely on independent contractors 

and temporary personnel to supplement our workforce, primarily in our logistics network. None of our employees are 
represented by a labor union or covered by a collective bargaining agreement. We consider our relationship with our employees 
to be good.

Seasonality

Our business is affected by seasonality, which historically has resulted in higher sales volume during our fourth quarter, 

which ends December 31.

Intellectual Property

Our intellectual property, including any trademarks, service marks, copyrights, domain names, patents, trade dress, trade 

secrets and proprietary technologies, is an important part of our business. To protect our intellectual property, we rely on a 
combination of laws and regulations, as well as contractual restrictions. We pursue the registration of our trademarks, including 
"Wayfair" and certain variations thereon, copyrights and domain names in the U.S. and certain foreign locations. We also rely on 
the protection of laws regarding unregistered copyrights for our proprietary software and certain other content we create. We will 
continue to evaluate the merits of applying for copyright registrations in the future. We have an issued patent regarding our 
proprietary technology and we are evaluating additional patent applications. We expect to consider filing patent applications for 
future technology inventions. We also rely on trade secret laws to protect our proprietary technology and other intellectual 
property. To further protect our intellectual property, we enter into confidentiality and assignment of invention assignment 
agreements with employees and certain contractors and confidentiality agreements with other third parties, such as suppliers.

Company Information

We began operating as Smart Tech Toys, Inc., a Massachusetts corporation, in May 2002 and changed our name to CSN 

Stores, Inc. in February 2003. From 2002 through 2011, the Company was bootstrapped by our co-founders and operated as 
hundreds of niche websites, such as bedroomfurniture.com and allbarstools.com. In March 2008, we formed, and contributed all 
of the assets and liabilities of CSN Stores, Inc. to a subsidiary, CSN Stores LLC, and we continued operating our business 
through this Delaware limited liability company. In late 2011, we made the strategic decision to close and permanently redirect 
over 240 of our niche websites into Wayfair.com. As part of that shift, we changed the name of CSN Stores, Inc. to SK 
Retail, Inc. and changed our name from CSN Stores LLC to Wayfair LLC.  In connection with our initial public offering, we 
completed a corporate reorganization, as a result of which Wayfair Inc. was formed to be a holding company with no material 
assets other than 100% of the equity interests in Wayfair LLC and SK Retail, Inc. 

Our executive offices are located at 4 Copley Place, 7th Floor, Boston, MA 02116, and our telephone number is 
(617) 532-6100. Our corporate website address is www.wayfair.com. The information contained in, or accessible through, our 
website does not constitute part of this Annual Report on Form 10-K.

grow certain categories where we under index the broader home goods market today, such as home improvement, 
housewares, seasonal decor and decorative accents;

enhance the systems our consumers use to interact with our sites and invest in our infrastructure platform;

expand internationally; and

opportunistically pursue strategic acquisitions.

We cannot assure you we will be able to achieve any of the foregoing. Our customer base may not continue to grow or may 
decline as a result of increased competition and the maturation of our business. Failure to continue our revenue growth rates could 
have a material adverse effect on our financial condition and results of operations. You should not rely on our historical rate of 
revenue growth as an indication of our future performance.

If we fail to manage our growth effectively, our business, financial condition and operating results could be harmed.

To manage our growth effectively, we must continue to implement our operational plans and strategies, improve and expand 
our infrastructure of people and information systems and expand, train and manage our employee base. We have rapidly increased 
employee headcount since our inception to support the growth in our business. To support continued growth, we must effectively 
integrate, develop and motivate a large number of new employees. We face significant competition for personnel, particularly in 
the Boston, Massachusetts area where our headquarters are located. Failure to manage our hiring needs effectively or successfully 
integrate our new hires may have a material adverse effect on our business, financial condition and operating results.

Additionally, the growth of our business places significant demands on our management and other employees. For example, 

we typically launch hundreds of promotional events across thousands of products each month on our sites via emails, "push" 
notifications and personalized displays. These events require us to produce updates of our sites and emails to our customers on a 
daily basis with different products, photos and text. The growth of our business may require significant additional resources to 
meet these daily requirements, which may not scale in a cost-effective manner or may negatively affect the quality of our sites and 
customer experience. We are also required to manage relationships with a growing number of suppliers, customers and other third 
parties. Our information technology systems and our internal controls and procedures may not be adequate to support future

growth of our supplier and employee base. If we are unable to manage the growth of our organization effectively, our business, 
financial condition and operating results may be materially adversely affected.

If we fail to acquire new customers or retain existing customers, or fail to do so in a cost-effective manner, we may not be 

able to achieve profitability.

Our success depends on our ability to acquire and retain customers in a cost-effective manner. In order to expand our 
customer base, we must appeal to and acquire customers who have historically used other means of commerce to purchase home 
goods and may prefer alternatives to our offerings, such as traditional brick and mortar retailers, the websites of our competitors 
or our suppliers' own websites. We have made significant investments related to customer acquisition and expect to continue to 
spend significant amounts to acquire additional customers. Our paid advertising efforts consist primarily of online channels, 
including search engine marketing, display advertising, and paid social media, and to a lesser extent direct mail and television 
advertisements. These efforts are expensive and may not result in the cost-effective acquisition of customers. We cannot assure 
you that the net profit from new customers we acquire will ultimately exceed the cost of acquiring those customers. If we fail to 
deliver a quality shopping experience, or if consumers do not perceive the products we offer to be of high value and quality, we 
may not be able to acquire new customers. If we are unable to acquire new customers who purchase products in numbers 
sufficient to grow our business, we may not be able to generate the scale necessary to drive beneficial network effects with our 
suppliers, our net revenue may decrease, and our business, financial condition and operating results may be materially adversely 
affected.

We believe that many of our new customers originate from word-of- mouth and other non-paid referrals from existing 
customers. Therefore, we must ensure that our existing customers remain loyal to us in order to continue receiving those referrals. 
If our efforts to satisfy our existing customers are not successful, we may not be able to acquire new customers in sufficient 
numbers to continue to grow our business, or we may be required to incur significantly higher marketing expenses in order to 
acquire new customers.

We also utilize non-paid advertising. Our non-paid advertising efforts include search engine optimization, non-paid social 
media, mobile "push" notifications and email. We obtain a significant amount of traffic via search engines and, therefore, rely on 
search engines such as Google, Bing and Yahoo!. Search engines frequently update and change the logic that determines the 
placement and display of results of a user's search, such that the purchased or algorithmic placement of links to our sites can be 
negatively affected. Moreover, a search engine could, for competitive or other purposes, alter its search algorithms or results, 
causing our sites to place lower in search query results. A major search engine could change its algorithms in a manner that 
negatively affects our paid or non-paid search ranking, and competitive dynamics could impact the effectiveness of search engine 
marketing or search engine optimization. We also obtain a significant amount of traffic via social networking websites or other 
channels used by our current and prospective customers. As e-commerce and social networking continue to rapidly evolve, we 
must continue to establish relationships with these channels and may be unable to develop or maintain these relationships on 
acceptable terms. If we are unable to cost-effectively drive traffic to our sites, our ability to acquire new customers and our 
financial condition would suffer.

Our success depends in part on our ability to increase our net revenue per active customer. If our efforts to increase 
customer loyalty and repeat purchasing as well as maintain high levels of customer engagement are not successful, our growth 
prospects and revenue will be materially adversely affected.

Our ability to grow our business depends on our ability to retain our existing customer base and generate increased revenue 
and repeat purchases from this customer base, and maintain high levels of customer engagement. To do this, we must continue to 
provide our customers and potential customers with a unified, convenient, efficient and differentiated shopping experience by:

• 

providing imagery, tools and technology that attract customers who historically would have bought elsewhere;

•  maintaining a high-quality and diverse portfolio of products;

• 

delivering products on time and without damage; and

•  maintaining and further developing our mobile platforms.

If we fail to increase net revenue per active customer, generate repeat purchases or maintain high levels of customer 

engagement, our growth prospects, operating results and financial condition could be materially adversely affected.

Our business depends on our ability to build and maintain strong brands. We may not be able to maintain and enhance 

our brands if we receive unfavorable customer complaints, negative publicity or otherwise fail to live up to consumers' 
expectations, which could materially adversely affect our business, results of operations and growth prospects.

Maintaining and enhancing our brands is critical to expanding our base of customers and suppliers. However, a significant 

portion of our customers' brand experience depends on third parties outside of our control, including suppliers and logistics 
providers such as FedEx, UPS, the U.S. Postal Service and other third-party delivery agents. If these third parties do not meet our 
or our customers' expectations, our brands may suffer irreparable damage. In addition, maintaining and enhancing these brands 
may require us to make substantial investments, and these investments may not be successful. If we fail to promote and maintain 
our brands, or if we incur excessive expenses in this effort, our business, operating results and financial condition may be 
materially adversely affected. We anticipate that, as our market becomes increasingly competitive, maintaining and enhancing our 
brands may become increasingly difficult and expensive. Maintaining and enhancing our brands will depend largely on our ability 
to provide high quality products to our customers and a reliable, trustworthy and profitable sales channel to our suppliers, which 
we may not be able to do successfully.

Customer complaints or negative publicity about our sites, products, delivery times, customer data handling and security 

practices or customer support, especially on blogs, social media websites and our sites, could rapidly and severely diminish 
consumer use of our sites and consumer and supplier confidence in us and result in harm to our brands.

Our efforts to expand our business into new brands, products, services, technologies, and geographic regions will subject 

us to additional business, legal, financial, and competitive risks and may not be successful.

Our business success depends to some extent on our ability to expand our customer offerings by launching new brands and 

services and by expanding our existing offerings into new geographies. For example, in 2017 we launched Perigold, and a number 
of new house brands, and in 2016 we launched Wayfair.ca in Canada as well as Wayfair Registry, our wedding registry service. 
Launching new brands and services or expanding internationally requires significant upfront investments, including investments 
in marketing, information technology, and additional personnel. Expanding our brands internationally is particularly challenging 
because it requires us to gain country-specific knowledge about consumers, regional competitors and local laws, construct 
catalogs specific to the country, build local logistics capabilities and customize portions of our technology for local markets. We 
may not be able to generate satisfactory revenue from these efforts to offset these costs. Any lack of market acceptance of our 
efforts to launch new brands and services or to expand our existing offerings could have a material adverse effect on our business, 
prospects, financial condition and results of operations. Further, as we continue to expand our fulfillment capability or add new 
businesses with different requirements, our logistics networks become increasingly complex and operating them becomes more 
challenging.  There can be no assurance that we will be able to operate our networks effectively.

We have also entered and may continue to enter into new markets in which we have limited or no experience, which may 

not be successful or appealing to our customers. These activities may present new and difficult technological and logistical 
challenges, and resulting service disruptions, failures or other quality issues may cause customer dissatisfaction and harm our 
reputation and brand. Further, our current and potential competitors in new market segments may have greater brand recognition, 
financial resources, longer operating histories and larger customer bases than we do in these areas. As a result, we may not be 
successful enough in these newer areas to recoup our investments in them. If this occurs, our business, financial condition and 
operating results may be materially adversely affected.

Expansion of our international operations will require management attention and resources, involves additional risks, 

and may be unsuccessful, which could harm our future business development and existing domestic operations.

We believe international expansion represents a significant growth opportunity for us. Today, we deliver products to 
customers in a number of countries, and plan to expand into other international markets in order to grow our business, which will 
require significant management attention and resources. For example, we have made and will continue to make significant 
investments in information technology, logistics, supplier relationships, merchandising and marketing in the foreign jurisdictions 
in which we operate or plan to operate. We have limited experience in selling our products to conform to different local cultures, 
standards and regulations, and the products we offer may not appeal to customers in the same manner, if at all, in other 
geographies. We may have to compete with local companies which understand the local market better than we do and/or may 
have greater brand recognition than we do. In addition, to deliver satisfactory performance for customers in international 
locations, it may be necessary to locate physical facilities, such as consolidation centers and warehouses, in foreign markets, and 
we may have to invest in these facilities before we can determine whether or not our foreign operations are successful. We have 
limited experience establishing such facilities internationally and therefore may decide not to continue with the expansion of 
international operations. We may not be successful in expanding into additional international markets or in generating net revenue

from foreign operations. Furthermore, different privacy, censorship, liability, intellectual property and other laws and regulations 
in foreign countries may cause our business, financial condition and operating results to be materially adversely affected.

Our future results could be materially adversely affected by a number of factors inherent in international operations, 

including:

• 

• 

• 

localization of our product offerings, including translation into foreign languages and adaptation for local practices, 
standards and regulations;

the need to vary our practices in ways with which we have limited or no experience or which are less profitable or 
carry more risk to us;

unexpected changes in regulatory requirements, taxes, trade laws, tariffs, export quotas, custom duties or other trade 
restrictions;

• 

differing labor regulations where labor laws may be more advantageous to employees as compared to the U.S.;

•  more stringent regulations relating to data privacy and security, including the use of commercial and personal 

information, particularly in the European Union;

• 

• 

• 

• 

• 

• 

• 

• 

• 

changes in a specific country's or region's political or economic conditions;

the rising cost of labor in the foreign countries in which our suppliers operate, resulting in increases in our costs of 
doing business internationally;

challenges inherent in efficiently managing an increased number of employees over large geographic distances, 
including the need to implement appropriate systems, policies, benefits and compliance programs and maintain our 
corporate culture across geographies;

risks resulting from changes in currency exchange rates;

limitations on our ability to reinvest earnings from operations in one country to fund the capital needs of our 
operations in other countries;

different or lesser intellectual property protection;

exposure to liabilities under anti-corruption and anti-money laundering laws, including the U.S. Foreign Corrupt 
Practices Act and similar laws and regulations in other jurisdictions;

import/export controls; and

logistics and sourcing.

Operating internationally requires significant management attention and financial resources. We cannot be certain that the 
investment and additional resources required to establish and expand our international operations will produce desired levels of 
net revenue or profitability. If we invest substantial time and resources to establish and expand our international operations and 
are unable to do so successfully and in a timely manner, our business, financial condition and operating results may be materially 
adversely affected.

We have a history of losses and expect to have operating losses and negative cash flow as we continue to expand our 

business.

We have a history of losses, and we accumulated $306.2 million in common members' deficit as Wayfair LLC and an 
additional $583.3 million loss as Wayfair Inc. through December 31, 2017. Because the market for purchasing home goods online 
is rapidly evolving and has not yet reached widespread adoption, it is difficult for us to predict our future operating results. As a 
result, our losses may be larger than anticipated, and we may never achieve profitability. Also, we expect our operating expenses 
to increase over the next several years as we expand internationally, grow our proprietary logistics network, hire more employees 
and continue to develop new brands, features and services. Furthermore, if our future growth and operating performance fail to 
meet investor or analyst expectations, or if we have future negative cash flow or losses resulting from our investment in acquiring 
new customers, our financial condition and stock price could be materially adversely affected.

System interruptions that impair customer access to our sites or other performance failures in our technology 

infrastructure or that of our critical technology partners could damage our business, reputation and brand and substantially 
harm our business and results of operations.

The satisfactory performance, reliability and availability of our sites, transaction processing systems and technology 
infrastructure are critical to our reputation and our ability to acquire and retain customers, as well as maintain adequate customer 
service levels.

For example, if one of our data centers fails or suffers an interruption or degradation of services, we could lose customer 

data and miss order fulfillment deadlines, which could harm our business. Our systems and operations are also vulnerable to 
damage or interruption from fire, flood, power loss, telecommunications failure, terrorist attacks, cyber-attacks, data loss, acts of 
war, break-ins, earthquake and similar events. In the event of a data center failure, the failover to a back-up could take substantial 
time, during which time our sites could be completely shut down. Further, our back-up services may not effectively process spikes 
in demand, may process transactions more slowly and may not support all of our sites' functionality.

We use complex proprietary software in our technology infrastructure, which we seek to continually update and improve. 
We may not always be successful in executing these upgrades and improvements, and the operation of our systems may be subject 
to failure. In particular, we have in the past and may in the future experience slowdowns or interruptions in some or all of our sites 
when we are updating them, and new technologies or infrastructures may not be fully integrated with existing systems on a timely 
basis, or at all. Additionally, if we expand our use of third-party services, including cloud-based services, our technology 
infrastructure may be subject to increased risk of slowdown or interruption as a result of integration with such services and/or 
failures by such third-parties, which are out of our control. Our net revenue depends on the number of visitors who shop on our 
sites and the volume of orders we can handle. Unavailability of our sites or reduced order fulfillment performance would reduce 
the volume of goods sold and could also materially adversely affect consumer perception of our brand. 

We may experience periodic system interruptions from time to time. In addition, continued growth in our transaction 
volume, as well as surges in online traffic and orders associated with promotional activities or seasonal trends in our business, 
place additional demands on our technology platform and could cause or exacerbate slowdowns or interruptions. If there is a 
substantial increase in the volume of traffic on our sites or the number of orders placed by customers, we will be required to 
further expand and upgrade our technology, transaction processing systems and network infrastructure. There can be no assurance 
that we will be able to accurately project the rate or timing of increases, if any, in the use of our sites or expand and upgrade our 
systems and infrastructure to accommodate such increases on a timely basis. In order to remain competitive, we must continue to 
enhance and improve the responsiveness, functionality and features of our sites, which is particularly challenging given the rapid 
rate at which new technologies, customer preferences and expectations and industry standards and practices are evolving in the e-
commerce industry. Accordingly, we redesign and enhance various functions on our sites on a regular basis, and we may 
experience instability and performance issues as a result of these changes.

Any slowdown or failure of our sites and the underlying technology infrastructure could harm our business, reputation and 

our ability to acquire, retain and serve our customers, which could materially adversely affect our results of operations. Our 
disaster recovery plan may be inadequate, and our business interruption insurance may not be sufficient to compensate us for the 
losses that could occur.

Our business is highly competitive. Competition presents an ongoing threat to the success of our business.

Our business is rapidly evolving and intensely competitive, and we have many competitors in different industries. Our 
competition includes furniture stores, big box retailers, department stores, specialty retailers, and online retailers and marketplaces 
in the U.S., Canada, the United Kingdom and Germany, including:

•  Furniture Stores: Ashley Furniture, Bob's Discount Furniture, Havertys, Raymour & Flanagan, Rooms To Go;

•  Big Box Retailers: Bed Bath & Beyond, Home Depot, IKEA, Lowe's, Target and Walmart;

•  Department Stores: JCPenney and Macy's;

• 

Specialty Retailers: Crate and Barrel, Ethan Allen, TJX, At Home, Williams Sonoma, Restoration Hardware, 
Arhaus, Horchow, Room & Board, Mitchell Gold + Bob Williams; 

•  Online Retailers and Online Marketplaces: Amazon, Houzz and eBay; and

• 

International: Leon's, Canadian Tire, John Lewis, WorldStores, Otto and Home24, in addition to several of the 
companies listed above who also compete with us internationally.

We expect competition in e-commerce generally to continue to increase. We believe that our ability to compete successfully 

depends upon many factors both within and beyond our control, including:

• 

• 

• 

• 

• 

• 

• 

the size and composition of our customer base;

the number of suppliers and products we feature on our sites;

our selling and marketing efforts;

the quality, price and reliability of products we offer;

the convenience of the shopping experience that we provide;

our ability to distribute our products and manage our operations; and

our reputation and brand strength.

Many of our current competitors have, and potential competitors may have, longer operating histories, greater brand 
recognition, larger fulfillment infrastructures, greater technical capabilities, faster and less costly shipping, significantly greater 
financial, marketing and other resources and larger customer bases than we do. These factors may allow our competitors to derive 
greater net revenue and profits from their existing customer base, acquire customers at lower costs or respond more quickly than 
we can to new or emerging technologies and changes in consumer habits. These competitors may engage in more extensive 
research and development efforts, undertake more far-reaching marketing campaigns and adopt more aggressive pricing policies, 
which may allow them to build larger customer bases or generate net revenue from their customer bases more effectively than we 
do.

Purchasers of home goods may not choose to shop online, which would prevent us from growing our business.

The online market for home goods in the U.S. is less developed than the online market for apparel, consumer electronics and 

other consumer products in the U.S. and, we believe, only accounts for a small portion of the market as a whole. If the online 
market for home goods does not gain acceptance, our business may suffer. Our success will depend, in part, on our ability to 
attract consumers who have historically purchased home goods through traditional retailers. Furthermore, we may have to incur 
significantly higher and more sustained advertising and promotional expenditures in order to attract additional online consumers 
to our sites and convert them into purchasing customers. Specific factors that could impact consumers' willingness to purchase 
home goods from us include:

• 

• 

• 

• 

• 

• 

concerns about buying products, and in particular larger products, without a physical storefront, face-to-face 
interaction with sales personnel and the ability to physically examine products;

delivery time associated with online orders;

actual or perceived lack of security of online transactions and concerns regarding the privacy of personal 
information;

delayed shipments or shipments of incorrect or damaged products;

inconvenience associated with returning or exchanging items purchased online; and

usability, functionality and features of our sites.

If the shopping experience we provide does not appeal to consumers or meet the expectations of existing customers, we may 

not acquire new customers at rates consistent with historical periods, and existing customers' buying patterns and levels may be 
less than historical rates.

We may be subject to product liability claims if people or property are harmed by the products we sell.

Some of the products we sell may expose us to product liability claims and litigation (including class actions) or regulatory 

action relating to safety, personal injury, death or environmental or property damage. Some of our agreements with members of 
our supply chain may not indemnify us from product liability for a particular product, and some members of our supply chain 
may not have sufficient resources or insurance to satisfy their indemnity and defense obligations. Although we maintain liability 
insurance, we cannot be certain that our coverage will be adequate for liabilities actually incurred or that insurance will continue 
to be available to us on economically reasonable terms, or at all.

Risks associated with the suppliers from whom our products are sourced could materially adversely affect our financial 

performance as well as our reputation and brand.

We depend on our ability to provide our customers with a wide range of products from qualified suppliers in a timely and 
efficient manner. Political and economic instability, the financial stability of suppliers, suppliers' ability to meet our standards, 
labor problems experienced by suppliers, the availability of raw materials, merchandise quality issues, currency exchange rates, 
transport availability and cost, transport security, inflation, and other factors relating to our suppliers are beyond our control.

Our agreements with most of our suppliers do not provide for the long-term availability of merchandise or the continuation 

of particular pricing practices, nor do they usually restrict such suppliers from selling products to other buyers. There can be no 
assurance that our current suppliers will continue to seek to sell us products on current terms or that we will be able to establish 
new or otherwise extend current supply relationships to ensure product acquisitions in a timely and efficient manner and on 
acceptable commercial terms. Our ability to develop and maintain relationships with reputable suppliers and offer high quality 
merchandise to our customers is critical to our success. If we are unable to develop and maintain relationships with suppliers that 
would allow us to offer a sufficient amount and variety of quality merchandise on acceptable commercial terms, our ability to 
satisfy our customers' needs, and therefore our long-term growth prospects, would be materially adversely affected.

Further, we rely largely on our suppliers’ representations of product quality, safety and compliance with applicable laws and 

standards. If our suppliers or other vendors violate applicable laws, regulations or our supplier code of conduct, or implement 
practices regarded as unethical, unsafe, or hazardous to the environment, it could damage our reputation and negatively affect our 
operating results. Further, concerns regarding the safety and quality of products provided by our suppliers could cause our 
customers to avoid purchasing those products from us, or avoid purchasing products from us altogether, even if the basis for the 
concern is outside of our control. As such, any issue, or perceived issue, regarding the quality and safety of any items we sell, 
regardless of the cause, could adversely affect our brand, reputation, operations and financial results. 

13

Table of Contents

We also are unable to predict whether any of the countries in which our suppliers' products are currently manufactured or 

may be manufactured in the future will be subject to trade restrictions imposed by the U.S. or foreign governments or the 
likelihood, type or effect of any such restrictions. Any event causing a disruption or delay of imports from suppliers with 
international manufacturing operations, including the imposition of additional import restrictions, restrictions on the transfer of 
funds or increased tariffs or quotas, could increase the cost or reduce the supply of merchandise available to our customers and 
materially adversely affect our financial performance as well as our reputation and brand. Furthermore, some or all of our 
suppliers' foreign operations may be adversely affected by political and financial instability, resulting in the disruption of trade 
from exporting countries, restrictions on the transfer of funds or other trade disruptions.

In addition, our business with foreign suppliers, particularly with respect to our international sites, may be affected by 
changes in the value of the U.S. dollar relative to other foreign currencies. For example, any movement by any other foreign 
currency against the U.S. dollar may result in higher costs to us for those goods. Declines in foreign currencies and currency 
exchange rates might negatively affect the profitability and business prospects of one or more of our foreign suppliers. This, in 
turn, might cause such foreign suppliers to demand higher prices for merchandise in their effort to offset any lost profits 
associated with any currency devaluation, delay merchandise shipments, or discontinue selling to us altogether, any of which 
could ultimately reduce our sales or increase our costs.

We may be unable to source new suppliers or strengthen our relationships with current suppliers.

We have relationships with over 10,000 suppliers. Our agreements with suppliers are generally terminable at will by either 
party upon short notice. If we do not maintain our existing relationships or build new relationships with suppliers on acceptable 
commercial terms, we may not be able to maintain a broad selection of merchandise, and our business and prospects would suffer 
severely.

In order to attract quality suppliers to our platform, we must:

• 

• 

• 

demonstrate our ability to help our suppliers increase their sales;

offer suppliers a high quality, cost-effective fulfillment process; and

continue to provide suppliers with a dynamic and real-time view of our demand and inventory needs.

If we are unable to provide our suppliers with a compelling return on investment and an ability to increase their sales, we 

may be unable to maintain and/or expand our supplier network, which would negatively impact our business.

We depend on our suppliers to perform certain services regarding the products that we offer.

As part of offering our suppliers' products for sale on our sites, these suppliers are often responsible for conducting a 
number of traditional retail operations with respect to their respective products, including maintaining inventory and preparing 
merchandise for shipment to our customers. In these instances, we may be unable to ensure that these suppliers will continue to 
perform these services to our or our customers' satisfaction in a manner that provides our customer with a unified brand 
experience or on commercially reasonable terms. If our customers become dissatisfied with the services provided by our 
suppliers, our business, reputation and brands could suffer.

We depend on our relationships with third parties, and changes in our relationships with these parties could adversely 

impact our revenue and profits.

Because we rely on FedEx, UPS and the U.S. Postal Service to deliver most of the small parcel products we offer on our 

sites, we are subject to shipping delays or disruptions caused by inclement weather, natural disasters, labor activism, health 
epidemics or bioterrorism. In addition, because we rely on national, regional and local transportation companies for the delivery 
of some of our other products, we are also subject to risks of breakage or other damage during delivery by any of these third 
parties. We also use and rely on other services from third parties, such as our telecommunications services, and those services may 
be subject to outages and interruptions that are not within our control. For example, failures by our telecommunications providers 
have in the past and may in the future interrupt our ability to provide phone support to our customers. If products are not delivered 
in a timely fashion or are damaged during the delivery process, or if we are not able to provide adequate customer support, our 
customers could become dissatisfied and cease buying products through our sites, which would adversely affect our operating 
results.

14

Table of Contents

We also have relationships with third-party retail partners that allow consumers to purchase products offered by us though 
their websites and mobile applications. Because our agreements with our retail partners are generally terminable at will, we may 
be unable to maintain these relationships, and our results of operations could fluctuate significantly from period to period 
depending on the performance of our retail partners and their willingness to continue to offer and/or promote our products. Our 
agreements with our retail partners may also restrict our ability to market certain products, and not all of our suppliers may permit 
us to market through all of our retail partners' websites . Because some of our retail partners are competitors or potential 
competitors in the home goods market, some or all of our retail partners may in the future determine they no longer wish to do 
business with us or may decide to take other actions that could harm our business. We may also determine that we no longer want 
to do business with them. Because we do business with a small number of retail partners, if any one of our contracts with our 
retailer partners were to terminate, our revenue from our retail partners may decline and our relationships with our suppliers may 
be adversely affected.

If our internal control over financial reporting or our disclosure controls and procedures are not effective, we may not be 

able to accurately report our financial results, prevent fraud or file our periodic reports in a timely manner, which may cause 
investors to lose confidence in our reported financial information and may lead to a decline in our stock price.

The Sarbanes-Oxley Act of 2002 requires that we maintain effective internal control over financial reporting and disclosure 

controls and procedures. In particular, we must perform system and process evaluation, document our controls and perform 
testing of our key control over financial reporting to allow management and our independent public accounting firm to report on 
the effectiveness of our internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act. Our 
testing, or the subsequent testing by our independent public accounting firm, may reveal deficiencies in our internal control over 
financial reporting that are deemed to be material weaknesses. If we are not able to comply with the requirements of Section 404 
in a timely manner, or if we or our accounting firm identify deficiencies in our internal control over financial reporting that are 
deemed to be material weaknesses, the market price of our stock would likely decline and we could be subject to lawsuits, 
sanctions or investigations by regulatory authorities, including SEC enforcement actions, and we could be required to restate our 
financial results, any of which would require additional financial and management resources.

We continue to invest in more robust technology and in more resources in order to manage those reporting requirements. 

Implementing the appropriate changes to our internal controls may distract our officers and employees, result in substantial costs 
and require significant time to complete. Any difficulties or delays in implementing these controls could impact our ability to 
timely report our financial results. For these reasons, we may encounter difficulties in the timely and accurate reporting of our 
financial results, which would impact our ability to provide our investors with information in a timely manner. As a result, our 
investors could lose confidence in our reported financial information, and our stock price could decline.

In addition, any such changes do not guarantee that we will be effective in maintaining the adequacy of our internal 

controls, and any failure to maintain that adequacy could prevent us from accurately reporting our financial results.

We may be unable to accurately forecast net revenue and appropriately plan our expenses in the future.

Net revenue and operating results are difficult to forecast because they generally depend on the volume, timing, and type of 

orders we receive, all of which are uncertain. We base our expense levels and investment plans on our estimates of total net 
revenue and gross margins. We cannot be sure the same growth rates, trends, and other key performance metrics are meaningful 
predictors of future growth. If our assumptions prove to be wrong, we may spend more than we anticipate acquiring and retaining 
customers or may generate less net revenue per active customer than anticipated, any of which could have a negative impact on 
our business and results of operations. 

Our business is also affected by general economic and business conditions in the U.S., and we anticipate that it will be 

increasingly affected by conditions in international markets. In addition, we experience seasonal trends in our business, and our 
mix of product offerings is highly variable from day-to-day and quarter-to-quarter. This variability makes it difficult to predict 
sales and could result in significant fluctuations in our net revenue from period-to-period. A significant portion of our expenses is 
fixed, and as a result, we may be unable to adjust our spending in a timely manner to compensate for any unexpected shortfall in 
net revenue. Any failure to accurately predict net revenue or gross margins could cause our operating results to be lower than 
expected, which could materially adversely affect our financial condition and stock price.

Our ability to raise capital in the future may be limited, and our failure to raise capital when needed could prevent us 

from growing.

In the future, we could be required to or may decide to raise capital through public or private financing or other 

arrangements. Such financing may not be available on acceptable terms, or at all, and our failure to raise capital when needed or 
desired could harm our business. We may sell Class A common stock, convertible securities and other equity securities in one or 
more transactions at prices and in a manner as we may determine from time to time. If we sell any such securities in subsequent 
transactions, holders of our Class A common stock, including holders of any Class A common stock issued upon conversion of 
our convertible notes, may be materially diluted. New investors in such subsequent transactions could gain rights, preferences and 
privileges senior to those of holders of our Class A common stock. Debt financing, if available, may involve restrictive covenants 
and could reduce our operational flexibility or profitability. If we cannot raise funds on acceptable terms, we may not be able to 
grow our business or respond to competitive pressures.

Our business may be adversely affected if we are unable to provide our customers a cost-effective shopping platform that 

is able to respond and adapt to rapid changes in technology.

The number of people who access the Internet through devices other than personal computers, including mobile phones, 

smartphones, handheld computers such as notebooks and tablets, video game consoles, and television set-top devices, has 
increased dramatically in the past few years. We continually upgrade existing technologies and business applications to keep pace 
with these rapidly changing and continuously evolving technologies, and we may be required to implement new technologies or 
business applications in the future. The implementation of these upgrades and changes requires significant investments and as 
new devices and platforms are released, it is difficult to predict the problems we may encounter in developing applications for 
these alternative devices and platforms. Additionally, we may need to devote significant resources to the support and maintenance 
of such applications once created. Our results of operations may be affected by the timing, effectiveness and costs associated with 
the successful implementation of any upgrades or changes to our systems and infrastructure to accommodate such alternative 
devices and platforms. Further, in the event that it is more difficult or less compelling for our customers to buy products from us 
on their mobile or other devices, or if our customers choose not to buy products from us on such devices or to use mobile or other 
products that do not offer access to our sites, our customer growth could be harmed and our business, financial condition and 
operating results may be materially adversely affected.

Significant merchandise returns could harm our business.

We allow our customers to return products, subject to our return policy. If merchandise returns are significant, our business, 
prospects, financial condition and results of operations could be harmed. Further, we modify our policies relating to returns from 
time to time, which may result in customer dissatisfaction or an increase in the number of product returns. Many of our products 
are large and require special handling and delivery. From time to time our products are damaged in transit, which can increase 
return rates and harm our brand.

Uncertainties in global economic conditions and their impact on consumer spending patterns, particularly in the home 

goods segment, could adversely impact our operating results.

Consumers may view a substantial portion of the products we offer as discretionary items rather than necessities. As a 
result, our results of operations are sensitive to changes in macro-economic conditions that impact consumer spending, including 
discretionary spending. Some of the factors adversely affecting consumer spending include levels of unemployment, consumer 
debt levels, changes in net worth based on market changes and uncertainty, home foreclosures and changes in home values, 
fluctuating interest rates, credit availability, government actions, fluctuating fuel and other energy costs, fluctuating commodity 
prices and general uncertainty regarding the overall future economic environment. Adverse economic changes in any of the 
regions in which we sell our products could reduce consumer confidence and could negatively affect net revenue and have a 
material adverse effect on our operating results.

Our business relies heavily on email and other messaging services, and any restrictions on the sending of emails or 
messages or an inability to timely deliver such communications could materially adversely affect our net revenue and business.

Our business is highly dependent upon email and other messaging services for promoting our sites and products. Daily 
promotions offered through emails and other messages sent by us, or on our behalf by our vendors, generate a significant portion 
of our revenue. We provide daily emails and "push" communications to customers and other visitors informing them of what is 
available for purchase on our sites that day, and we believe these messages are an important part of our customer experience and 
help generate a substantial portion of our net revenue. If we are unable to successfully deliver emails or other messages to our 
subscribers, or if subscribers decline to open our emails or other messages, our net revenue and profitability would be materially 
adversely affected. Changes in how webmail applications organize and prioritize email may reduce the number of subscribers 
opening our emails. For example, in 2013 Google Inc.'s Gmail service began offering a feature that organizes incoming emails 
into categories (for example, primary, social and promotions). Such categorization or similar inbox organizational features may 
result in our emails being delivered in a less prominent location in a subscriber's inbox or viewed as "spam" by our subscribers 
and may reduce the likelihood of that subscriber opening our emails. Actions by third parties to block, impose restrictions on or 
charge for the delivery of emails or other messages could also adversely impact our business. From time to time, Internet service 
providers or other third parties may block bulk email transmissions or otherwise experience technical difficulties that result in our 
inability to successfully deliver emails or other messages to third parties. Changes in the laws or regulations that limit our ability 
to send such communications or impose additional requirements upon us in connection with sending such communications would 
also materially adversely impact our business. Our use of email and other messaging services to send communications about our 
sites or other matters may also result in legal claims against us, which may cause us increased expenses, and if successful might 
result in fines and orders with costly reporting and compliance obligations or might limit or prohibit our ability to send emails or 
other messages. We also rely on social networking messaging services to send communications and to encourage customers to 
send communications. Changes to the terms of these social networking services to limit promotional communications, any 
restrictions that would limit our ability or our customers' ability to send communications through their services, disruptions or 
downtime experienced by these social networking services or decline in the use of or engagement with social networking services 
by customers and potential customers could materially adversely affect our business, financial condition and operating results.

We are subject to risks related to online payment methods.

We accept payments using a variety of methods, including credit card, debit card, PayPal, credit accounts (including 

promotional financing) and gift cards. As we offer new payment options to consumers, we may be subject to additional 
regulations, compliance requirements and fraud. For certain payment methods, including credit and debit cards, we pay 
interchange and other fees, which may increase over time and raise our operating costs and lower profitability. We also offer co-
branded credit card programs, which could adversely affect our operating results if terminated. We are also subject to payment 
card association operating rules and certification requirements, including the Payment Card Industry Data Security Standard and 
rules governing electronic funds transfers, which could change or be reinterpreted to make it difficult or impossible for us to 
comply. As our business changes, we may also be subject to different rules under existing standards, which may require new 
assessments that involve costs above what we currently pay for compliance. If we fail to comply with the rules or requirements of 
any provider of a payment method we accept, if the volume of fraud in our transactions limits or terminates our rights to use 
payment methods we currently accept, or if a data breach occurs relating to our payment systems, we may, among other things, be 
subject to fines or higher transaction fees and may lose, or face restrictions placed upon, our ability to accept credit card and debit 
card payments from consumers or to facilitate other types of online payments. If any of these events were to occur, our business, 
financial condition and operating results could be materially adversely affected.

We occasionally receive orders placed with fraudulent credit card data. We may suffer losses as a result of orders placed 

with fraudulent credit card data even if the associated financial institution approved payment of the orders. Under current credit 
card practices, we may be liable for fraudulent credit card transactions. If we are unable to detect or control credit card fraud, our 
liability for these transactions could harm our business, financial condition and results of operations.

Government regulation of the Internet and e-commerce is evolving, and unfavorable changes or failure by us to comply 

with these regulations could substantially harm our business and results of operations.

We are subject to general business regulations and laws as well as regulations and laws specifically governing the Internet 

and e-commerce. Existing and future regulations and laws could impede the growth of the Internet, e- commerce or mobile 
commerce. These regulations and laws may involve taxes, tariffs, privacy and data security, anti-spam, content protection, 
electronic contracts and communications, consumer protection, Internet neutrality and gift cards. It is not clear how existing laws 
governing issues such as property ownership, sales and other taxes and consumer privacy apply to the Internet as the vast majority 
of these laws were adopted prior to the advent of the Internet and do not contemplate or address the unique issues raised by the 
Internet or e-commerce. It is possible that general business regulations and laws, or those specifically governing the Internet or e-
commerce, may be interpreted and applied in a manner that is inconsistent from one jurisdiction to another and may conflict with 
other rules or our practices. We cannot be sure that our practices have complied, comply or will comply fully with all such laws 
and regulations. Any failure, or perceived failure, by us to comply with any of these laws or regulations could result in damage to 
our reputation, a loss in business and proceedings or actions against us by governmental entities or others. Any such proceeding or 
action could hurt our reputation, force us to spend significant amounts in defense of these proceedings, distract our management, 
increase our costs of doing business, decrease the use of our sites by consumers and suppliers and may result in the imposition of 
monetary liability. We may also be contractually liable to indemnify and hold harmless third parties from the costs or 
consequences of non-compliance with any such laws or regulations. In addition, it is possible that governments of one or more 
countries may seek to censor content available on our sites or may even attempt to completely block access to our sites. Adverse 
legal or regulatory developments could substantially harm our business. In particular, in the event that we are restricted, in whole 
or in part, from operating in one or more countries, our ability to retain or increase our customer base may be adversely affected, 
and we may not be able to maintain or grow our net revenue and expand our business as anticipated. Further, as we enter into new 
market segments or geographical areas and expand the products and services we offer, we may be subject to additional laws and 
regulatory requirements or prohibited from conducting our business, or certain aspects of it, in certain jurisdictions. We will incur 
additional costs complying with these additional obligations and any failure or perceived failure to comply would adversely affect 
our business and reputation.

Failure to comply with federal, state and international laws and regulations relating to privacy, data protection and 

consumer protection, or the expansion of current or the enactment of new laws or regulations relating to privacy, data 
protection and consumer protection, could adversely affect our business and our financial condition.

A variety of federal, state and international laws and regulations govern the collection, use, retention, sharing, export and 
security of personal information. Laws and regulations relating to privacy, data protection and consumer protection are evolving 
and subject to potentially differing interpretations. These requirements may be interpreted and applied in a manner that is 
inconsistent from one jurisdiction to another or may conflict with other rules or our practices. As a result, our practices may not 
comply, or may not comply in the future with all such laws, regulations, requirements and obligations. Any failure, or perceived 
failure, by us to comply with our posted privacy policies or with any federal, state or international privacy or consumer 
protection- related laws, regulations, industry self-regulatory principles, industry standards or codes of conduct, regulatory 
guidance, orders to which we may be subject or other legal obligations relating to privacy or consumer protection could adversely 
affect our reputation, brand and business, and may result in claims, proceedings or actions against us by governmental entities or 
others or other liabilities or require us to change our operations and/or cease using certain data sets. Any such claim, proceeding 
or action could hurt our reputation, brand and business, force us to incur significant expenses in defense of such proceedings, 
distract our management, increase our costs of doing business, result in a loss of customers and suppliers and may result in the 
imposition of monetary penalties. We may also be contractually required to indemnify and hold harmless third parties from the 
costs or consequences of non-compliance with any laws, regulations or other legal obligations relating to privacy or consumer 
protection or any inadvertent or unauthorized use or disclosure of data that we store or handle as part of operating our business.

Federal, state and international governmental authorities continue to evaluate the privacy implications inherent in the use of 
proprietary or third-party "cookies" and other methods of online tracking for behavioral advertising and other purposes. U.S. and 
foreign governments have enacted, have considered or are considering legislation or regulations that could significantly restrict 
the ability of companies and individuals to engage in these activities, such as by regulating the level of consumer notice and 
consent required before a company can employ cookies or other electronic tracking tools or the use of data gathered with such 
tools. Additionally, some providers of consumer devices and web browsers have implemented, or announced plans to implement, 
means to make it easier for Internet users to prevent the placement of cookies or to block other tracking technologies, which could 
if widely adopted significantly reduce the effectiveness of such practices and technologies. The regulation of the use of cookies 
and other current online tracking and advertising practices or a loss in our ability to make effective use of services that employ 
such technologies could increase our costs of operations and limit our ability to acquire new customers on cost-effective terms 
and consequently, materially adversely affect our business, financial condition and operating results.

Foreign data protection, privacy and other laws and regulations are often more restrictive than those in the U.S. The 

European Union, for example, traditionally has imposed stricter obligations under its laws and regulations relating to privacy, data 
protection and consumer protection than the U.S. In May 2018 the European Union's new regulation governing data practices and 
privacy called the General Data Protection Regulation ("GDPR") becomes effective and will replace the data protection laws of 
the individual member states.  The law requires companies to meet new, more stringent requirements regarding the handling of 
personal data of individuals in the EU.  Engineering efforts to build new capabilities to facilitate compliance with GDPR may 
entail substantial expense and the diversion of engineering resources from other projects.  The law also increases the penalties for 
non-compliance, which may result in monetary penalties of up to 20 million Euros or 4% of a company's worldwide turnover, 
whichever is higher. GDPR and other similar regulations require companies to give specific types of notice and in some cases 
seek consent from consumers and other data subjects before collecting or using their data for certain purposes, including some 
marketing activities. Outside of the European Union, there are many countries with data protection laws, and new countries are 
adopting data protection legislation with increasing frequency. Many of these laws may require consent from consumers for the 
use of data for various purposes, including marketing, which may reduce our ability to market our products. There is no 
harmonized approach to these laws and regulations globally. Consequently, we increase our risk of non-compliance with 
applicable foreign data protection laws and regulations as we continue our international expansion. We may need to change and 
limit the way we use personal information in operating our business and may have difficulty maintaining a single operating model 
that is compliant. Compliance with such laws and regulations will result in additional costs and may necessitate changes to our 
business practices and divergent operating models, which may adversely affect our business and financial condition.

In addition, various federal, state and foreign legislative and regulatory bodies, or self-regulatory organizations, may expand 
current laws or regulations, enact new laws or regulations or issue revised rules or guidance regarding privacy, data protection and 
consumer protection. Any such changes may force us to incur substantial costs or require us to change our business practices. This 
could compromise our ability to pursue our growth strategy effectively and may adversely affect our ability to acquire customers 
or otherwise harm our business, financial condition and operating results.

Our failure or the failure of third-party service providers to protect our sites, networks and systems against security 
breaches, or otherwise to protect our confidential information, could damage our reputation and brand and substantially harm 
our business and operating results.

We collect, maintain, transmit and store data about our customers, employees, contractors, suppliers, vendors and others, 

including credit card information and personally identifiable information, as well as other confidential and proprietary 
information. We also employ third-party service providers that store, process and transmit certain proprietary, personal and 
confidential information on our behalf. We rely on encryption and authentication technology licensed from third parties in an 
effort to securely transmit, encrypt, anonymize or pseudonymize certain confidential and sensitive information, including credit 
card numbers. Advances in computer capabilities, new technological discoveries or other developments may result in the whole or 
partial failure of this technology to protect transaction and personal data or other confidential and sensitive information from 
being breached or compromised. Our security measures, and those of our third-party service providers, may not detect or prevent 
all attempts to hack our systems, denial-of-service attacks, viruses, malicious software, break-ins, phishing attacks, social 
engineering, security breaches or other attacks and similar disruptions that may jeopardize the security of information stored in or 
transmitted by our sites, networks and systems or that we or our third-party service providers otherwise maintain, including 
payment card systems and human resources management platforms. We and our service providers may not anticipate or prevent 
all types of attacks until after they have already been launched, and techniques used to obtain unauthorized access to or sabotage 
systems change frequently and may not be known until launched against us or our third-party service providers. In addition, 
security breaches can also occur as a result of non-technical issues, including intentional or inadvertent breaches by our 
employees or by persons with whom we have commercial relationships.

19

Table of Contents

Breaches of our security measures or those of our third-party service providers or cyber security incidents could result in 
unauthorized access to our sites, networks and systems; unauthorized access to and misappropriation of personal information, 
including consumers' and employees' personally identifiable information, or other confidential or proprietary information of 
ourselves or third parties; limited or terminated access to certain payment methods or fines or higher transaction fees to use such 
methods; viruses, worms, spyware or other malware being served from our sites, networks or systems; deletion or modification of 
content or the display of unauthorized content on our sites; interruption, disruption or malfunction of operations; costs relating to 
breach remediation, deployment or training of additional personnel and protection technologies, responses to governmental 
investigations and media inquiries and coverage; engagement of third party experts and consultants; litigation, regulatory action 
and other potential liabilities. If any of these breaches of security occur, our reputation and brand could be damaged, our business 
may suffer, we could be required to expend significant capital and other resources to alleviate problems caused by such breaches 
and we could be exposed to a risk of loss, litigation or regulatory action and possible liability. In addition, any party who is able to 
illicitly obtain a customer's password could access that customer's transaction data or personal information. Any compromise or 
breach of our security measures, or those of our third-party service providers, could violate applicable privacy, data security and 
other laws, and cause significant legal and financial exposure, adverse publicity and a loss of confidence in our security measures, 
which could have a material adverse effect on our business, financial condition and operating results. Although we maintain 
privacy, data breach and network security liability insurance, we cannot be certain that our coverage will be adequate for 
liabilities actually incurred or that insurance will continue to be available to us on economically reasonable terms, or at all. We 
may need to devote significant resources to protect against security breaches or to address problems caused by breaches, diverting 
resources from the growth and expansion of our business.

Changes in tax treatment of companies engaged in e-commerce may adversely affect the commercial use of our sites and 

our financial results.

Due to the global nature of the Internet, it is possible that various states or foreign countries might attempt to impose 
additional or new regulation on our business or levy additional or new sales, income or other taxes relating to our activities. Tax 
authorities at the international, federal, state and local levels are currently reviewing the appropriate treatment of companies 
engaged in e-commerce. New or revised international, federal, state or local tax regulations or court decisions may subject us or 
our customers to additional sales, income and other taxes. For example, Congress is considering various approaches to legislation 
that would require companies engaged in e-commerce to collect sales tax taxes on Internet revenue and a growing number of U.S. 
states and certain foreign jurisdictions have adopted or are considering proposals to impose obligations on remote sellers and 
online marketplaces to collect taxes on their behalf. Additionally, we are a defendant in a legal proceeding (South Dakota v. 
Wayfair Inc., 17-494) where South Dakota has asked the U.S. Supreme Court to reverse its longstanding precedent holding that 
remote sellers are not required to collect state and local sales taxes. We cannot predict the effect of these and other attempts to 
impose sales, income or other taxes on e-commerce. New or revised taxes and, in particular, sales taxes, VAT and similar taxes 
would likely increase the cost of doing business online and decrease the attractiveness of selling products over the Internet. New 
taxes could also create significant increases in internal costs necessary to capture data and collect and remit taxes. Any of these 
events could have a material adverse effect on our business, financial condition and operating results.

Taxing authorities may successfully assert that we should have collected or in the future should collect sales and use, 

commercial activity, VAT or similar taxes, and we could be subject to liability with respect to past or future sales, which could 
adversely affect our operating results.

We do not collect and remit sales and use, commercial activity, VAT or similar taxes in all jurisdictions in which we have 
sales, based on our belief that such taxes are not applicable or legally required. Several states and other taxing jurisdictions have 
presented or threatened us with assessments, alleging that we are required to collect and remit such taxes there. Other states, 
including South Dakota in our legal proceeding currently before the U.S. Supreme Court (South Dakota v. Wayfair Inc., 17-494), 
have requested that courts validate new laws that reverse existing constitutional precedent. While we do not believe that we are 
subject to such taxes and intend to vigorously defend our position in these cases, we cannot be sure of the outcome of our 
discussions and/or appeals with these states or cases that are pending in the courts. In the event of an adverse outcome, we could 
face assessments for additional time periods since the last assessments we received, plus any additional interest and penalties. We 
also expect additional jurisdictions may make similar assessments or pass similar new laws in the future, and any of the 
jurisdictions where we have sales may apply more rigorous enforcement efforts or take more aggressive positions in the future 
that could result in greater tax liability allegations. In addition, in the future we may also decide to engage in activities, such as 
owning or leasing property, that would require us to pay sales and use, commercial activity, VAT or similar taxes in new 
jurisdictions. Such tax assessments, penalties and interest or future requirements may materially adversely affect our business, 
financial condition and operating results.

Our business could suffer if we are unsuccessful in making, integrating and maintaining acquisitions and investments.

As part of our business strategy, we may acquire other companies or businesses. However, we may not be able to find 
suitable acquisition candidates, and we may not be able to complete acquisitions on favorable terms, if at all. Acquisitions involve 
numerous risks, any of which could harm our business, including: difficulties in integrating the technologies, operations, existing 
contracts and personnel of an acquired company; difficulties in supporting and transitioning customers and suppliers, if any, of an 
acquired company; diversion of financial and management resources from existing operations or alternative acquisition 
opportunities; failure to realize the anticipated benefits or synergies of a transaction; failure to identify all of the problems, 
liabilities or other shortcomings or challenges of an acquired company or technology, including issues related to intellectual 
property, regulatory compliance practices, revenue recognition or other accounting practices or employee or customer issues; risks 
of entering new markets in which we have limited or no experience; potential loss of key employees, customers and suppliers 
from either our current business or an acquired company's business; inability to generate sufficient net revenue to offset 
acquisition costs; additional costs or equity dilution associated with funding the acquisition; and possible write-offs or impairment 
charges relating to acquired businesses.

In addition, our investments in properties may not be fully realized. We continually review our operations and facilities in 
an effort to reduce costs and increase efficiencies. For strategic or other operational reasons, we may decide to consolidate or co-
locate certain aspects of our business operations or dispose of one or more of our properties. If we decide to fully or partially 
vacate a leased property, we may incur significant cost, including facility closing costs, employee separation and retention 
expenses, lease termination fees, rent expense in excess of sublease income and impairment of leasehold improvements and 
accelerated depreciation of assets. Any of these events may materially adversely affect our business, financial condition and 
operating results.

We rely on the performance of members of management and highly skilled personnel, and if we are unable to attract, 

develop, motivate and retain well-qualified employees, our business could be harmed.

We believe our success has depended, and continues to depend, on the efforts and talents of Niraj Shah, one of our co-
founders, co-chairman of the board of directors and our Chief Executive Officer, Steven Conine, one of our co-founders and co-
chairman of the board of directors, and the other members of our senior management team. Our future success depends on our 
continuing ability to attract, develop, motivate and retain highly qualified and skilled employees, particularly mid-level managers, 
engineers and merchandising and technology personnel. The market for such positions in the Boston area and other cities in which 
we operate is competitive. Qualified individuals are in high demand, and we may incur significant costs to attract them. In 
addition, the loss of any of our senior management or key employees or our inability to recruit and develop mid-level managers 
could materially adversely affect our ability to execute our business plan, and we may not be able to find adequate replacements. 
All of our officers and other U.S. employees are at-will employees, meaning that they may terminate their employment 
relationship with us at any time, and their knowledge of our business and industry would be extremely difficult to replace. If we 
do not succeed in attracting well-qualified employees or retaining and motivating existing employees, our business, financial 
condition and operating results may be materially adversely affected.

We may not be able to adequately protect our intellectual property rights.

We regard our customer lists, trademarks, domain names, copyrights, patents, trade dress, trade secrets, proprietary 
technology and similar intellectual property as critical to our success, and we rely on trademark, copyright and patent law, trade 
secret protection, agreements and other methods with our employees and others to protect our proprietary rights. We might not be 
able to obtain broad protection in the U.S. or internationally for all of our intellectual property, and we might not be able to obtain 
effective intellectual property protection in every country in which we sell products or perform services. For example, we are the 
registrant of marks for our brands in numerous jurisdictions and of the Internet domain name for the websites of Wayfair.com, 
Wayfair.co.uk, Wayfair.de and our other sites, as well as various related domain names. However, we have not registered our 
marks or domain names in all major international jurisdictions and may not be able to register or use such domain names in all of 
the countries in which we currently or intend to conduct business. Further, we might not be able to prevent third parties from 
registering, using or retaining domain names that interfere with our consumer communications or infringe or otherwise decrease 
the value of our marks, domain names and other proprietary rights.

21

Table of Contents

The protection of our intellectual property rights may require the expenditure of significant financial, managerial and 

operational resources. We may initiate claims or litigation against others for infringement, misappropriation or violation of our 
intellectual property rights or proprietary rights or to establish the validity of such rights. Any litigation, whether or not it is 
resolved in our favor, could result in significant expense to us and divert the efforts of our technical and management personnel, 
which may materially adversely affect our business, financial condition and operating results. Moreover, the steps we take to 
protect our intellectual property may not adequately protect our rights or prevent third parties from infringing or misappropriating 
our proprietary rights, and we may not be able to broadly enforce all of our trademarks or patents. Any of our patents, marks or 
other intellectual property rights may be challenged by others or invalidated through administrative process or litigation. Our 
patent and trademark applications may never be granted. Additionally, the process of obtaining intellectual property protections is 
expensive and time-consuming, and we may not be able to pursue all necessary or desirable actions at a reasonable cost or in a 
timely manner. Even if issued, there can be no assurance that these protections will adequately safeguard our intellectual property, 
as the legal standards relating to the validity, enforceability and scope of protection of patent and other intellectual property rights 
are uncertain. We also cannot be certain that others will not independently develop or otherwise acquire equivalent or superior 
technology or intellectual property rights. We may also be exposed to claims from third parties claiming infringement of their 
intellectual property rights, or demanding the release or license of open source software or derivative works that we developed 
using such software (which could include our proprietary code) or otherwise seeking to enforce the terms of the applicable open 
source license. These claims could result in litigation and could require us to purchase a costly license, publicly release the 
affected portions of our source code, be limited in or cease using the implicated software unless and until we can re-engineer such 
software to avoid infringement or change the use of the implicated open source software.

We have been, and may again be, accused of infringing intellectual property rights of third parties.

The e-commerce industry is characterized by vigorous protection and pursuit of intellectual property rights, which has 
resulted in protracted and expensive litigation for many companies. We are subject to claims and litigation by third parties that we 
infringe their intellectual property rights, and we expect additional claims and litigation with respect to infringement to occur in 
the future. The costs of supporting such litigation and disputes are considerable, and there can be no assurances that favorable 
outcomes will be obtained. As our business expands and the number of competitors in our market increases and overlaps occur, 
we expect that infringement claims may increase in number and significance. Any claims or proceedings against us, whether 
meritorious or not, could be time-consuming, result in considerable litigation costs, require significant amounts of management 
time or result in the diversion of significant operational resources, any of which could materially adversely affect our business, 
financial condition and operating results.

Legal claims regarding intellectual property rights are subject to inherent uncertainties due to the oftentimes complex issues 
involved, and we cannot be certain that we will be successful in defending ourselves against such claims. In addition, some of our 
larger competitors have extensive portfolios of issued patents. Many potential litigants, including patent holding companies, have 
the ability to dedicate substantially greater resources to enforce their intellectual property rights and to defend claims that may be 
brought against them. Furthermore, a successful claimant could secure a judgment that requires us to pay substantial damages or 
prevents us from conducting our business as we have historically done or may desire to do in the future. We might also be 
required to seek a license and pay royalties for the use of such intellectual property, which may not be available on commercially 
acceptable terms, or at all. Alternatively, we may be required to develop non-infringing technology or intellectual property, which 
could require significant effort and expense and may ultimately not be successful.

We have received in the past, and we may receive in the future, communications alleging that certain items posted on or 

sold through our sites violate third-party copyrights, designs, marks and trade names or other intellectual property rights or other 
proprietary rights. Brand and content owners and other proprietary rights owners have actively asserted their purported rights 
against online companies, including Wayfair. In addition to litigation from rights owners, we may be subject to regulatory, civil or 
criminal proceedings and penalties if governmental authorities believe we have aided and abetted in the sale of counterfeit or 
infringing products.

Such claims, whether or not meritorious, may result in the expenditure of significant financial, managerial and operational 
resources, injunctions against us or the payment of damages by us. We may need to obtain licenses from third parties who allege 
that we have violated their rights, but such licenses may not be available on terms acceptable to us, or at all. These risks have been 
amplified by the increase in third parties whose sole or primary business is to assert such claims.

Our outstanding indebtedness, or additional indebtedness that we may incur, could adversely affect our financial condition.

In September 2017, we issued unsecured 0.375% Convertible Senior Notes in an aggregate principal amount of $431.25 

million (the "Notes"), pursuant to which we will pay interest semiannually in arrears at a rate of 0.375% per annum commencing 
in 2018.  The Notes will mature on September 1, 2022 unless earlier purchased, redeemed or converted, at which time, we will 
settle any conversions of the Notes in cash, shares of the Company’s Class A common stock or a combination thereof, at our 
election. Under certain circumstances, the holders of the Notes may require us to repay all or a portion of the principal and 
interest outstanding under the Notes in cash prior to the maturity date, which could have an adverse effect on our financial results.

In February 2017, we entered into a three-year senior secured revolving credit facility (the "Revolver") under which we may 

borrow up to $100 million to fund working capital and general corporate purposes. If we draw down on this facility, our interest 
expense and principal repayment requirements will increase, which could have an adverse effect on our financial results and our 
ability to make payments on the Notes. Further, the agreements governing the Revolver contain numerous requirements, including 
affirmative, negative and financial covenants.  Our failure to comply with any of these covenants or to meet any payment 
obligations under the Revolver could result in an event of default which, if not cured or waived, would result in any amounts 
outstanding, including any accrued interest and unpaid fees, becoming immediately due and payable.  We might not have 
sufficient working capital or liquidity to satisfy any repayment obligations in the event of an acceleration of those obligations.  

Our business may not be able to generate sufficient cash flow from operations, and we can give no assurance that future 

borrowings will be available to us in amounts sufficient to enable us to pay our indebtedness as such indebtedness matures, 
including the Notes, and to fund our other liquidity needs. If this occurs, we will need to refinance all or a portion of our 
indebtedness on or before maturity, and there can be no assurance that we will be able to refinance any of our indebtedness on 
commercially reasonable terms, or at all. We may need to adopt one or more alternatives, such as reducing or delaying planned 
expenses and capital expenditures, selling assets, restructuring debt, or obtaining additional equity or debt financing. These 
alternative strategies may not be affected on satisfactory terms, if at all. Our ability to refinance our indebtedness or obtain 
additional financing, or to do so on commercially reasonable terms, will depend on, among other things, our financial condition at 
the time, restrictions in agreements governing our indebtedness, and other factors, including the condition of the financial markets 
and the markets in which we compete.

If we do not generate sufficient cash flow from operations, and additional borrowings, refinancings or proceeds from asset 
sales are not available to us, we may not have sufficient cash to enable us to meet all of our obligations, including our obligations 
under the Notes.

We cannot guarantee that our stock repurchase program will be fully consummated or that it will enhance long-term 
shareholder value. Stock repurchases could also increase the volatility of the trading price of our stock and could diminish our 
cash reserves.

In February 2018, our board of directors authorized a stock repurchase program of up to $200 million of our Class A 
common stock that does not have an expiration date. Although our board of directors has authorized this stock repurchase 
program, the program does not obligate us to repurchase any specific dollar amount or to acquire any specific number of shares.  
We cannot guarantee that the program will be fully consummated or that it will enhance long-term stockholder value. The 
program could affect the trading price of our Class A common stock and increase volatility, and any announcement of a 
termination of this program may result in a decrease in the trading price of our Class A common stock. In addition, this program 
could diminish our cash reserves.

Risks Related to Ownership of our Class A Common Stock

The dual class structure of our common stock has the effect of concentrating voting control with our co-founders, which 

will limit your ability to influence corporate matters.

Our Class B common stock has ten votes per share, and our Class A common stock, which is the stock that is publicly 
traded, has one vote per share. Following our initial public offering (the "IPO"), our Class B common stock was held primarily by 
our co-founders, other executive officers, directors and their affiliates. Due to optional conversions of Class B common stock into 
Class A common stock following the IPO, our Class B common stock is currently held primarily by our co-founders and their 
affiliates. As of December 31, 2017, our co-founders and their affiliates owned shares representing approximately 35.7% of the 
economic interest and 84.4% of the voting power of our outstanding capital stock. This concentrated control limits your ability to 
influence corporate matters for the foreseeable future. For example, these stockholders are able to control elections of directors, 
amendments of our certificate of incorporation or bylaws, increases to the number of shares available for issuance under our 
equity incentive plans or adoption of new equity incentive plans and approval of any merger or sale of assets for the foreseeable 
future. This control may materially adversely affect the market price of our Class A common stock. Additionally, holders of our 
Class B common stock may cause us to make strategic decisions or pursue acquisitions that could involve risks to you or may not 
be aligned with your interests. The holders of our Class B common stock are also entitled to a separate vote in the event we seek 
to amend our certificate of incorporation to increase or decrease the par value of a class of our common stock or in a manner that 
alters or changes the powers, preferences or special rights of the Class B common stock in a manner that affects its holders 
adversely.

Future transfers by holders of Class B common stock will generally result in those shares converting on a 1:1 basis to 
Class A common stock, which will have the effect, over time, of increasing the relative voting power of those holders of Class B 
common stock who retain their shares in the long-term, which may include our executive officers.

Our stock price may be volatile or may decline regardless of our operating performance.

The market price of our Class A common stock may fluctuate significantly in response to numerous factors, many of which 

are beyond our control, including the risks described elsewhere in this Part I, Item 1A, Risk Factors, of this Annual Report on 
Form 10-K, as well as:

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

actual or anticipated fluctuations in our results of operations;

the financial projections we may provide to the public, any changes in these projections or our failure to meet these 
projections;

failure of securities analysts to initiate or maintain coverage of our company, changes in financial estimates or 
ratings by any securities analysts who follow our company or our failure to meet these estimates or the expectations 
of investors;

announcements by us or our competitors of significant technical innovations, acquisitions, strategic partnerships, 
joint ventures, operating results or capital commitments;

changes in operating performance and stock market valuations of other technology or retail companies generally, or 
those in our industry in particular;

price and volume fluctuations in the overall stock market, including as a result of trends in the economy as a whole;

changes in interest rates;

changes in our board of directors or management;

sales of large blocks of our Class A common stock, including sales by our executive officers, directors and 
significant stockholders;

lawsuits threatened or filed against us;

changes in laws or regulations applicable to our business;

changes in our capital structure, such as future issuances of debt or equity securities;

short sales, hedging and other derivative transactions involving our capital stock;

general economic conditions in the U.S. and abroad; and

other events or factors, including those resulting from war, incidents of terrorism or responses to these events. 

In addition, stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect 

the market prices of equity securities of many technology companies, including e-commerce companies. Stock prices of many 
technology companies, including e-commerce companies, have fluctuated in a manner unrelated or disproportionate to the 
operating performance of those companies. Volatility in our stock price could adversely affect our business and financing 
opportunities and expose us to litigation. Securities litigation can subject us to substantial costs, divert resources and the attention 
of management from our business and materially adversely affect our business, financial condition and operating results.

Short selling could increase the volatility of our stock price. 

We believe our Class A common stock has been the subject of significant short selling efforts by certain market participants. 

Short sales are transactions in which a market participant sells a security that it does not own. To complete the transaction, the 
market participant must borrow the security to make delivery to the buyer. The market participant is then obligated to replace the 
security borrowed by purchasing the security at the market price at the time of required replacement. If the price at the time of 
replacement is lower than the price at which the security was originally sold by the market participant, then the market participant 
will realize a gain on the transaction. Thus, it is in the market participant’s interest for the market price of the underlying security 
to decline as much as possible during the period prior to the time of replacement. Short selling may negatively affect the value of 
our stock to the detriment of our stockholders. 

In addition, market participants with disclosed short positions in our stock have published, and may in the future continue to 

publish, negative information regarding us that we believe is inaccurate and misleading. We believe that the publication of this 
negative information may in the future lead to downward pressure on the price of our stock.

25

Table of Contents

Substantial sales of shares of our Class A common stock could cause the market price of our Class A common stock to 

decline.

Sales of a substantial number of shares of our Class A common stock in the public market, or the perception that these sales 
might occur, could depress the market price of our Class A common stock and could impair our ability to raise capital through the 
sale of additional equity securities. We are unable to predict the effect that such sales may have on the prevailing market price of 
our Class A common stock.

If securities or industry analysts do not publish research or reports about our business, or publish negative reports about 

our business, our share price and trading volume could decline.

The trading market for our Class A common stock depends in part on the research and reports that securities or industry 

analysts publish about us or our business, our market and our competitors. We do not have any control over these analysts. If one 
or more of the analysts who cover us downgrade our shares or change their opinion of our shares, our share price would likely 
decline. If one or more of these analysts cease coverage of our company or fail to regularly publish reports on us, we could lose 
visibility in the financial markets, which could cause our share price or trading volume to decline.

Our management has broad discretion over our existing cash resources and might not use such funds in ways that 

increase the value of your investment.

Our management generally has broad discretion over the use of our cash resources, and you will be relying on the judgment 

of our management regarding the application of these resources. Our management might not apply these resources in ways that 
increase the value of your investment.

Although we do not rely on "controlled company" exemptions from certain corporate governance requirements under 

the New York Stock Exchange, or NYSE, rules, if we use these exemptions in the future, you will not have the same 
protections afforded to stockholders of companies that are subject to such requirements.

Our co-founders control a majority of the voting power of our outstanding common stock. As a result, we qualify as a 

"controlled company" within the meaning of the corporate governance standards of the NYSE. Under these rules, a listed 
company of which more than 50% of the voting power is held by an individual, group or another company is a "controlled 
company" and may elect not to comply with certain corporate governance requirements, including:

• 

• 

• 

• 

the requirement that a majority of the board of directors consist of independent directors as defined under the listing 
rules of the NYSE;

the requirement that we have a nominating and corporate governance committee that is composed entirely of 
independent directors with a written charter addressing the committee's purpose and responsibilities;

the requirement that we have a compensation committee that is composed entirely of independent directors with a 
written charter addressing the committee's purpose and responsibilities; and

the requirement for an annual performance evaluation of the nominating and corporate governance and 
compensation committees.

To the extent we still qualify, we may choose to take advantage of any of these exemptions in the future. As a result, in the 

future, we may not have a majority of independent directors and we may not have independent director oversight of decisions 
regarding executive compensation and director nominations.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of our company 
more difficult, limit attempts by our stockholders to replace or remove our current management and limit the market price of 
our Class A common stock.

Provisions in our certificate of incorporation and bylaws may have the effect of delaying or preventing a change of control 

or changes in our management. Our certificate of incorporation and bylaws include provisions that:

• 

permit the board of directors to establish the number of directors and fill any vacancies and newly created 
directorships;

•  when the outstanding shares of our Class B common stock represent less than 10% of the then outstanding shares of 

Class A common stock and Class B common stock, provide that our board of directors will be classified into three 
classes with staggered, three year terms and that directors may only be removed for cause;

• 

• 

require super-majority voting to amend some provisions in our certificate of incorporation and bylaws;

authorize the issuance of "blank check" preferred stock that our board of directors could use to implement a 
stockholder rights plan;

• 

eliminate the ability of our stockholders to call special meetings of stockholders;

•  when the outstanding shares of our Class B common stock represent less than 10% of the then outstanding shares of 
Class A common stock and Class B common stock, prohibit stockholder action by written consent, which requires 
all stockholder actions to be taken at a meeting of our stockholders;

• 

• 

• 

• 

provide that the board of directors is expressly authorized to make, alter or repeal our bylaws;

restrict the forum for certain litigation against us to Delaware;

reflect the dual class structure of our common stock, as discussed above; and

establish advance notice requirements for nominations for election to our board of directors or for proposing matters 
that can be acted upon by stockholders at annual stockholder meetings.

These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management 

by making it more difficult for stockholders to replace members of our board of directors, which is responsible for appointing the 
members of our management. In addition, because we are incorporated in Delaware, we are governed by the provisions of 
Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of 
a broad range of business combinations with any holder of at least 15% of our capital stock for a period of three years following 
the date on which the stockholder became a 15% stockholder.

Holders of Our Common Stock

As of February 16, 2018, there were 24 holders of record of shares of our Class A common stock and 372 holders of record 

of shares of our Class B common stock. The actual number of stockholders is greater than this numbers of record holders, and

institutions.

Dividends

We do not expect to pay any dividends on our Class A common stock or Class B common stock in the foreseeable future. 

Any future determination to pay dividends will be at the sole discretion of our board of directors, subject to applicable laws. Our 
board of directors may take into account general and economic conditions, our financial condition and operating results, our 
available cash and current and anticipated cash needs, our capital requirements, contractual, legal, tax and regulatory restrictions, 
and implications on the payment of dividends by us to our stockholders or by our subsidiaries to us and such other factors as our 
board of directors may deem relevant.

Securities Authorized for Issuance Under Equity Compensation Plans

Information regarding our equity compensation plans and securities authorized for issuance thereunder is set forth under 
Part III, Item 12, Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters, of this 
Annual Report on Form 10-K.

Recent Sales of Unregistered Securities

During the three months ended December 31, 2017, we issued 165,104 shares of Class B common stock upon the vesting of 

outstanding restricted stock units, net of shares withheld to satisfy statutory minimum tax withholding obligations. The issuance 
of these securities was pursuant to written compensatory plans or arrangements with our employees, consultants, advisors and 
directors in reliance on the exemption provided by Rule 701 promulgated under the Securities Act, relative to transactions by an 
issuer not involving any public offering, to the extent an exemption from registration was required.

On September 15, 2017, we issued $431.25 million aggregate principal amount of 0.375% Convertible Senior Notes due 

2022 (the "Notes"), which includes the exercise in full of the $56.25 million over-allotment option, to Citigroup Global Markets 
Inc. and Goldman Sachs & Co. LLC as the initial purchasers of the Notes (the "Initial Purchasers"). Our offering of the Notes to 

28

 
Table of Contents

the Initial Purchasers was made in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act. 
We relied on this exemption from registration based in part on representations made by the Initial Purchasers, including that the 
Initial Purchasers would only offer, sell or deliver the Notes to persons inside the United States whom they reasonably believe to 
be qualified institutional buyers within the meaning of Rule 144A under the Securities Act.

Item 7.  Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion of our financial condition and results of operations should be read in conjunction with the 
consolidated financial statements and the notes thereto included elsewhere in this Annual Report on Form 10-K. This discussion 
contains forward-looking statements that involve risks and uncertainties. As a result of many factors, such as those included in 
the Special Note Regarding Forward Looking Statements and Part I, Item 1A, Risk Factors, of this Annual Report on Form 10-K, 
our actual results may differ materially from those anticipated in these forward-looking statements.

The following discussion includes financial information prepared in accordance with generally accepted accounting 
principles ("GAAP"), as well as certain adjusted or non-GAAP financial measures such as Adjusted EBITDA, non-GAAP diluted 
net loss per share and free cash flow. Generally, a non-GAAP financial measure is a numerical measure of financial performance, 
financial position or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly 
comparable measure calculated and presented in accordance with GAAP. Management believes the use of these non-GAAP 
measures on a consolidated and reportable segment basis assists investors in understanding the ongoing operating performance of 
our business by presenting comparable financial results between periods. For more information on these non-GAAP financial 
measures, including reconciliations to the most directly comparable GAAP financial measures, see "Non-GAAP Financial 
Measures" below.

Overview

We are one of the world's largest online destinations for the home. Through our e-commerce business model, we offer 
visually inspired browsing, compelling merchandising, easy product discovery and attractive prices for over ten million products 
from over 10,000 suppliers. 

We believe an increasing portion of the dollars spent on home goods will be spent online and that there is an opportunity 

for acquiring more market share. We plan to grow our net revenue by acquiring new customers as well as stimulating repeat 
purchases from our existing customers. Through increasing brand awareness and paid and unpaid advertising, we attract new and 
repeat customers to our sites. We then seek to convert that visitor traffic to sales through engaging visual imagery and 
merchandising, daily sales promotions, and easy-to-use navigation tools and personalization features that enable better product 
discovery. We carefully track and monitor the results of our advertising campaigns so that we can ensure that appropriate return 
targets are being met. 

Because of the large market opportunity we see in front of us, we are currently investing in several areas across our 
business. Over the last few years, we have invested in expanding our international business in Canada, the United Kingdom and 
Germany by building our international infrastructure, developing deeper country-specific knowledge, growing our international 
supplier networks and establishing our brand presence in select countries. Accordingly, our consolidated net loss of $244.6 
million in the year ended December 31, 2017 is primarily driven by our international expansion. 

We have also invested considerably in our proprietary logistics network over the last few years, including our CastleGate 

warehouses and our Wayfair Delivery Network, which includes consolidation centers, cross docks and last mile delivery 
facilities. We believe that our proprietary logistics network will help drive incremental sales by delighting our customers with 
faster delivery times and a better home delivery experience. Over time we believe this network will also lower our costs per 
order by reducing damage rates and leveraging economies of scale in transportation. We are also currently investing in new 
categories, such as home improvement (e.g. plumbing, lighting and flooring), housewares, seasonal decor and decorative 
accents, so that we can add more of those products to our sites and capture a higher share of our customers' spend on home 
goods.

Key Financial and Operating Metrics

We measure our business using both financial and operating metrics. Our free cash flow metric is measured on a 

consolidated basis. Our net revenue and Adjusted EBITDA metrics are measured on a consolidated and segment basis. See Note 
11 to the Consolidated Financial Statements, Segment and Geographic Information, included in Part II, Item 8, Financial 
Statements and Supplementary Data, of this Annual Report on Form 10-K. All other key financial and operating metrics are 
derived and reported from our Direct Retail sales, which includes sales generated primarily through our five distinct sites. These 
metrics do not include net revenue derived from the websites  operated by our retail partners and our media solutions business. 
We do not have access to certain customer level information on net revenue derived through our retail partners and therefore 
cannot measure or disclose it.

To provide investors with additional information regarding our financial results, we have disclosed here and elsewhere in 
this Annual Report on Form 10-K Adjusted EBITDA, a non-GAAP financial measure that we calculate as loss before depreciation 
and amortization, equity-based compensation and related taxes, interest and other income and expense, provision for income 
taxes, and non-recurring items. We have provided a reconciliation below of Adjusted EBITDA to net loss, the most directly 
comparable GAAP financial measure. 

We have included Adjusted EBITDA in this Annual Report on Form 10-K because it is a key measure used by our 
management and board of directors to evaluate our operating performance, generate future operating plans and make strategic 
decisions regarding the allocation of capital. In particular, the exclusion of certain expenses in calculating Adjusted EBITDA 
facilitates operating performance comparisons on a period-to-period basis. Accordingly, we believe that Adjusted EBITDA 
provides useful information to investors and others in understanding and evaluating our operating results in the same manner as 
our management and board of directors.

Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for 

analysis of our results as reported under GAAP. Some of these limitations are: 

•  Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be 

replaced in the future, and Adjusted EBITDA does not reflect cash capital expenditure requirements for such 
replacements or for new capital expenditure requirements;

•  Adjusted EBITDA does not reflect equity based compensation and related taxes;

•  Adjusted EBITDA does not reflect changes in our working capital;

•  Adjusted EBITDA does not reflect income tax payments that may represent a reduction in cash available to us;

•  Adjusted EBITDA does not reflect depreciation and interest expenses associated with the lease financing obligation; and

•  Other companies, including companies in our industry, may calculate Adjusted EBITDA differently, which reduces its 

usefulness as a comparative measure.

Because of these limitations, you should consider Adjusted EBITDA alongside other financial performance measures, 

including various cash flow metrics, net loss and our other GAAP results.

(1) We recorded $9.6 million of one-time charges in the year ended December 31, 2017 in "Selling, operations, technology, 

general and administrative" in the consolidated statements of operations related to a warehouse we vacated in July 2017. Of 
the $9.6 million charges, $8.8 million was included in "Other" and related primarily to the excess of our estimated future 
remaining lease commitments through 2023 over our expected sublease income over the same period, and $0.8 million was 
included in "Depreciation and amortization" related to accelerated depreciation of leasehold improvements in the warehouse.

Free Cash Flow

To provide investors with additional information regarding our financial results, we have also disclosed here and elsewhere 

in this Annual Report on Form 10-K free cash flow, a non-GAAP financial measure that we calculate as net cash provided by 
operating activities less net cash used to purchase property and equipment and site and software development costs. We have 
provided a reconciliation below of free cash flow to net cash provided by operating activities, the most directly comparable 
GAAP financial measure.

We have included free cash flow in this Annual Report on Form 10-K because it is an important indicator of our business 

performance as it measures the amount of cash we generate. Accordingly, we believe that free cash flow provides useful 
information to investors and others in understanding and evaluating our operating results in the same manner as our management.

Free cash flow has limitations as an analytical tool because it omits certain components of the cash flow statement and does 
not represent the residual cash flow available for discretionary expenditures. Further, other companies, including companies in our 
industry, may calculate free cash flow differently. Accordingly, you should not consider free cash flow in isolation or as a 
substitute for analysis of our results as reported under GAAP. Because of these limitations, you should consider free cash flow 
alongside other financial performance measures, including net cash provided by operating activities, capital expenditures and our 
other GAAP results.

The following table presents a reconciliation of free cash flow to net cash provided by operating activities for each of the 

periods indicated (in thousands):

Key Operating Metrics (Direct Retail)

Active Customers

As of the last date of each reported period, we determine our number of active customers by counting the total number of 

individual customers who have purchased at least once directly from our sites during the preceding twelve-month period. The 
change in active customers in a reported period captures both the inflow of new customers as well as the outflow of existing 
customers who have not made a purchase in the last twelve months. We view the number of active customers as a key indicator of 
our growth.

LTM Net Revenue Per Active Customer

We define LTM net revenue per active customer as our total net revenue derived from Direct Retail sales in the last twelve 
months divided by our total number of active customers for the same preceding twelve-month period. We view LTM net revenue 
per active customer as a key indicator of our customers' purchasing patterns, including their initial and repeat purchase behavior.

Orders Delivered

We define orders delivered as the total Direct Retail orders delivered in any period, inclusive of orders that may eventually 
be returned. As we ship a large volume of packages through multiple carriers, actual delivery dates may not always be available, 
and as such we estimate delivery dates based on historical data. We recognize net revenue when an order is delivered and 
therefore orders delivered, together with average order value, is an indicator of the net revenue we expect to recognize in a given 
period. We view orders delivered as a key indicator of our growth.

Average Order Value

We define average order value as total Direct Retail net revenue in a given period divided by the orders delivered in that 

period. We view average order value as a key indicator of the mix of products on our sites, the mix of offers and promotions and 
the purchasing behavior of our customers.

Factors Affecting our Performance

We believe that our performance and future success depend on a number of factors that present significant opportunities for 

us but also pose risks and challenges, including those discussed in Part I, Item 1A, Risk Factors.

Components of Our Results of Operations 

Net Revenue

Net revenue consists primarily of sales of product from our sites and through the websites  of our online retail partners and 
includes related shipping fees. We deduct cash discounts, allowances and estimated returns from gross revenue to determine net 
revenue. We recognize product revenue upon delivery to our customers. Net revenue is primarily driven by growth of new and 
active customers and the frequency with which customers purchase. The products offered on our sites are fulfilled with product 
we ship to our customers directly from our suppliers and, increasingly, from our CastleGate warehouses and through our Wayfair 
Delivery Network.

We also generate net revenue through third-party advertisers that pay us based on the number of advertisement related 
clicks, actions, or impressions for advertisements placed on our sites. Net revenue earned under these arrangements is included in 
net revenue and net revenue through our third-party advertisers is recognized in the period in which the click, action or impression 
occurs. This revenue has not been material to date.

Cost of Goods Sold

Cost of goods sold consists of the cost of product sold to customers, shipping and handling costs and shipping supplies and 
fulfillment costs. Fulfillment costs include costs incurred in operating and staffing fulfillment centers, such as costs attributed to 
receiving, inspecting, picking, packaging and preparing customer orders for shipment. Cost of goods sold also includes direct and 
indirect labor costs, including equity-based compensation, for fulfillment center oversight, including payroll and related benefit 
costs. The increase in cost of goods sold is primarily driven by growth in orders delivered, the mix of the product available for 
sale on our sites and transportation costs related to delivering orders to our customers.

We earn rebates on our incentive programs with our suppliers. These rebates are earned upon shipment of goods. Amounts 

due from suppliers as a result of these rebate programs are included as a receivable and are reflected as a reduction of cost of 

36

 
 
 
 
 
 
Table of Contents

goods sold on the consolidated statements of operations. We also perform logistics services for suppliers through our CastleGate 
and Wayfair Delivery Network solutions, which are earned upon completion of preparing customer orders for shipment and are 
reflected as a reduction of cost of goods sold on the consolidated statements of operations. 

We expect cost of goods sold expenses to remain relatively stable as a percentage of net revenue but some fluctuations are 

expected due to the wide variety of products we sell.

Customer Service and Merchant Fees

Customer service and merchant fees consist of labor-related costs, including equity-based compensation, of our employees 

involved in customer service activities and merchant processing fees associated with customer payments made by credit cards and 
debit cards. Increases in our customer service and merchant fees are driven by the growth in our revenue and are expected to 
remain relatively consistent as a percentage of revenue. We expect customer service and merchant fees to remain relatively stable 
as a percentage of net revenue. 

Advertising

Advertising consists of direct response performance marketing costs, such as display advertising, paid search advertising, 

social media advertising, search engine optimization, comparison shopping engine advertising, television advertising, direct mail, 
catalog and print advertising. We expect advertising expense to continue to increase but decrease as a percentage of net revenue 
over time due to our increasing base of repeat customers.

Selling, operations, technology, general and administrative 

Selling, operations, technology, general and administrative expenses primarily include labor-related costs, including equity-

based compensation, of our operations group which includes our supply chain and logistics team, our technology team, which 
builds and supports our sites, category managers, buyers, site merchandisers, merchants, marketers and the team who executes our 
advertising strategy, and our corporate general and administrative team, which includes human resources, finance and accounting 
personnel. Also included are administrative and professional service fees including audit and legal fees, insurance and other 
corporate expenses, including depreciation and rent. We expect selling, operations, technology, general and administrative 
expenses will continue to increase as we grow our net revenue and operations.

Interest (Expense) Income, Net

Interest (expense) income, net, in 2017, consists primarily of interest expense in connection with our Notes, which is 
payable at the rate of 0.375% semi-annually on March 1 and September 1 of each year, commencing on March 1, 2018, and, in 
2016 and 2017, the lease financing obligation, partially offset by interest earned on cash, cash equivalents and short-term and 
long-term investments held by us, in 2017, 2016, and 2015.

Other (Expense) Income, Net

Other (expense) income, net consists primarily of foreign currency (losses) gains, and in 2015, a $3.0 million gain related to 

the sale of our Australian operations.

In 2017, net revenue increased by $1.3 billion, or 39.7% compared to 2016, primarily as a result of an increase in Direct 
Retail net revenue as our U.S. and International businesses continued to scale. In 2017, Direct Retail net revenue increased by 
$1.4 billion, or 42.5% compared to 2016, primarily due to growth in our customer base, with the number of active customers 
increasing by 33.2% as of December 31, 2017 compared to December 31, 2016. Additionally, active customers on average spent 
more in 2017 than the prior year, with LTM net revenue per active customer increasing 6.8% as of December 31, 2017 compared 
to December 31, 2016. The decrease in Other revenue in 2017 compared to 2016 was primarily due to decreased sales through our 
retail partners, as we continue to focus more on our Direct Retail business.

Excluding the impact of equity based compensation and related taxes, customer service costs and merchant processing fees 

increased by $41.1 million in 2017 compared to 2016, primarily due to the increase in net revenue during 2017. 

Our advertising expenses increased by $140.8 million in 2017 compared to 2016, primarily as a result of an increase in 

online and television advertising. Advertising decreased as a percentage of net revenue in 2017 compared to 2016, primarily due 
to increased leverage from our growing base of repeat customers, and television advertising expense not increasing at the same 
rate as revenue growth in the U.S., partially offset by advertising investments in Europe and Canada.

Excluding the impact of equity based compensation and related taxes, selling, operations, technology, general and 

administrative expense increased by $148.3 million in 2017 compared to 2016. As our revenue continues to grow, we have 
invested in headcount in both operations and technology to continue to deliver a great experience for our customers. 
The increase in selling, operations, technology, general and administrative expense was primarily attributable to personnel costs, 
rent, information technology, and depreciation and amortization.

(1) We recorded $9.6 million of one-time charges in the three months ended September 30, 2017 in "Selling, operations, 

technology, general and administrative" in the unaudited consolidated and condensed statements of operations related to a 
warehouse we vacated in July 2017. Of the $9.6 million charges, $8.8 million was included in "Other" and related primarily to the 
excess of our estimated future remaining lease commitments through 2023 over our expected sublease income over the same 
period, and $0.8 million was included in "Depreciation and amortization" related to accelerated depreciation of leasehold 
improvements in the warehouse.

At December 31, 2017, our principal source of liquidity was cash and cash equivalents and short- and long-term investments 

totaling $641.6 million, which includes $420.4 million of net proceeds from the issuance of our Notes in September 2017, 
partially offset by $44.2 million in premiums paid at the same time for separate capped call transactions. We believe that our 
existing cash and cash equivalents and investments, together with cash generated from operations and the cash available under our 
revolving credit facility, will be sufficient to meet our anticipated cash needs for at least the foreseeable future. However, our 
liquidity assumptions may prove to be incorrect, and we could exhaust our available financial resources sooner than we currently 
expect. In addition, we may elect to raise additional funds at any time through equity, equity linked or debt financing 
arrangements.

Capital expenditures were 3.1% of net revenue for the year ended December 31, 2017 and related primarily to our ongoing 

investments in our technology infrastructure, and equipment purchases and improvements for leased warehouses within our 
expanding supply chain network. We expect capital expenditures to be approximately 4% of net revenue for the first quarter of 
2018, as we continue to build out our technology infrastructure and logistics network. 

Our future capital requirements and the adequacy of available funds will depend on many factors, including those described 

herein and in our other filings with the SEC, including those set forth under in Part I, Item 1A, Risk Factors, of this Annual 
Report on Form 10-K. We may not be able to secure additional financing to meet our operating requirements on acceptable terms, 
or at all. 

Operating Activities

Cash provided by operating activities consisted of net loss adjusted for certain non-cash items including depreciation and 

amortization, equity-based compensation, and certain other non-cash expenses, as well as the effect of changes in working capital 
and other activities.  Operating cash flows can be volatile and are sensitive to many factors, including changes in working capital 
and our net loss.

Cash provided by operating activities in the year ended December 31, 2017 was $33.6 million and was driven primarily by 

cash provided by operating assets and liabilities of $116.4 million, certain non-cash items including depreciation and amortization 
expense of $87.0 million, equity based compensation of $67.8 million, amortization of discount and issuance costs related to our 
Notes of $5.8 million and other non-cash items of $1.2 million, partially offset by net loss of $244.6 million.

Cash provided by operating activities in the year ended December 31, 2016 was $62.8 million and was driven primarily by 

cash provided by operating assets and liabilities of $151.9 million, certain non-cash items including depreciation and amortization 
expense of $55.6 million, equity based compensation of $49.4 million, and other non-cash items of $0.3 million, partially offset 
by net loss of $194.4 million. 

Cash provided by operating activities in the year ended December 31, 2015 was $135.1 million and was driven primarily by 
cash provided by operating assets and liabilities of $149.1 million, certain non-cash items including depreciation and amortization 
expense of $32.4 million, equity based compensation of $31.0 million, and other non-cash items of $3.0 million, partially offset 
by net loss of $77.4 million and gain on sale of our Australian business of $3.0 million. 

Investing Activities

Our primary investing activities consisted of purchases of property and equipment, particularly purchases of servers and 
networking equipment, investment in our sites and software development, purchases and disposal of short-term and long-term 
investments, and leasehold improvements for our facilities.

Cash used in investing activities in the year ended December 31, 2017 was $130.3 million and was primarily driven by 
purchases of property and equipment of $100.5 million, purchases of short-term and long-term investments of $54.5 million, and 
site and software development costs of $46.4 million, partially offset by sale and maturities of short-term investments of $71.1 
million. 

Cash used in investing activities in the year ended December 31, 2016 was $95.9 million and was primarily driven by 
purchases of property and equipment of $96.7 million, purchases of short-term and long-term investments of $88.1 million, site 
and software development costs of $31.4 million, and other net investing activities of $1.0 million, partially offset by sale and 
maturities of short-term investments of $119.8 million and cash received from the sale of a business (net of cash sold) of $1.5 
million.

Cash used in investing activities in the year ended December 31, 2015 was $137.7 million and was primarily driven by 

purchases of short-term and long-term investments of $207.3 million, property and equipment of purchases of property and 
equipment of $44.6 million, site and software development costs of $17.5 million, other net investing activities of $4.8 million, 
partially offset by sale and maturities of short-term investments of $133.6 million and cash received from the sale of a business 
(net of cash sold) of $2.9 million.

  Financing Activities

Cash provided by financing activities in the year ended December 31, 2017 was $375.0 million and was primarily due to 
$420.4 million of net proceeds from the issuance of our Notes and $0.2 million net proceeds from the exercise of stock options, 
partially offset by $44.2 million in premiums paid for separate capped call transactions, and $1.4 million statutory minimum taxes 
paid related to net share settlements of equity awards. As expected, our sell-to-cover policy, which began in the second half of 
2016 and requires employees to sell a portion of the shares they receive upon vesting of RSUs in order to cover any required 
withholding taxes, materially reduced cash used in financing activities related to taxes paid for net share settlement of equity 
awards. For additional information on the Notes, see Note 14, Convertible Debt, in the Notes to the Consolidated Financial 
Statements included in Part II, Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K.

Cash used in financing activities in the year ended December 31, 2016 was $20.9 million and was primarily due to statutory 

minimum taxes paid related to net share settlement of equity awards of $21.1 million, partially offset by net proceeds from 
exercise of stock options of $0.2 million. During 2016, we began requiring employees to sell a portion of the shares that they 
receive upon the vesting of RSUs in order to cover any required withholding taxes, rather than our policy of allowing employees 
to forfeit shares to us to settle the withholding taxes. This sell-to-cover policy was phased in over the course of 2017.

Cash used in financing activities in the year ended December 31, 2015 was $18.6 million and was primarily due to statutory 

minimum taxes paid related to net share settlement of equity awards of $19.1 million, partially offset by net proceeds from 
exercise of stock options of $0.5 million.

  Stock Repurchase Program

On February 22, 2018, we announced that our board of directors authorized the repurchase of up to $200 million of our 
Class A common stock. This repurchase program has no expiration but may be suspended or terminated by the board of directors 
at any time.  Under the repurchase program, we are authorized to repurchase, from time to time, outstanding shares of Class A 

47

 
Table of Contents

common stock in the open market, through privately negotiated transactions, or otherwise, including pursuant to a Rule 10b5-1 
plan.

The actual timing, number and value of shares repurchased will be determined by the Company in its discretion and will 
depend on a number of factors, including market conditions, applicable legal requirements, our capital needs and whether there is 
a better alternative use of capital.  We have no obligation to repurchase any amount of Class A common stock under the program.

  Credit Agreement and Convertible Notes

For information regarding our credit agreement and Notes, see Note 13, Credit Agreement, and Note 14, Convertible Debt, 
in the Notes to the Consolidated Financial Statements included in Part II, Item 8, Financial Statements and Supplementary Data, 
of this Annual Report on Form 10-K.

Off-Balance Sheet Arrangements

We do not engage in any off-balance sheet activities. We do not have any off-balance sheet interest in variable interest 

entities, which include special purpose entities and other structured finance entities.

We lease office space under non-cancelable leases. These leases expire at various dates through 2029 and include 

discounted rental periods and fixed escalation clauses, which are amortized straight-line over the terms of the lease. We recognize 
rent expense on a straight-line basis over the lease periods. For information regarding our lease obligations, see Note 
7, Commitments and Contingencies, in the Notes to the Consolidated Financial Statements included in Part II, Item 8, Financial 
Statements and Supplementary Data, of this Annual Report on Form 10-K.

Critical Accounting Policies

Our financial statements are prepared in accordance with accounting principles generally accepted in the U.S. The 
preparation of our financial statements and related disclosures requires us to make estimates, assumptions and judgments that 
affect the reported amount of assets, liabilities, net revenue, costs and expenses and related disclosures. We believe that the 
estimates, assumptions and judgments involved in the accounting policies described below have the greatest potential impact on 
our financial statements and, therefore, we consider these to be our critical accounting policies. Accordingly, we evaluate our 
estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions 
and conditions. See Note 2, Summary of Significant Accounting Policies, in the Notes to the Consolidated Financial Statements 
included in Part II, Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K for information 
about these critical accounting policies, as well as a description of our other significant accounting policies.

Revenue Recognition

We generate net revenue through product sales generated primarily through our five distinct sites and through websites  

operated by third parties.

We recognize revenue for product sales generated through our five distinct sites and through websites  operated by third 
parties only when the following four criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred; 
(3) the selling price is fixed or determinable; and (4) collectability is reasonably assured. We recognize net revenue from sales of 
our products upon delivery to the customer. As we ship a large volume of packages through multiple carriers, actual delivery dates 
may not always be available and as such we estimate delivery dates based on historical data. We record product revenue at the 
gross amount as we are the primary obligor with the customer and provide the primary customer service for all products sold, 
have latitude in establishing price and selecting products sold, have discretion in selecting suppliers of products sold, maintain 
inventory risk from shipment through delivery date and upon accepting returns, and have credit risk. Net revenue includes 
shipping costs charged to the customer and are recorded net of taxes collected from customers, which are remitted to

governmental authorities. Cash discounts, returns and rebates are deducted from gross revenue in determining net revenue. In 
addition, we defer revenue when cash is collected from our customer prior to the satisfaction of the revenue recognition criteria.

We maintain a membership rewards program for purchases made with our private label credit card, a Wayfair-branded credit 

card that can only be used at our five U.S. sites. Enrolled customers earn points that may be redeemed for future purchases. We 
defer a portion of our revenue associated with rewards that are ultimately expected to be redeemed.

We also earn revenue through third-party advertisers that pay based on the number of advertisement related clicks, actions, 
or impressions for ads placed on our sites. Revenue earned under these arrangements is included in net revenue and is recognized 
in the period in which the click, action, or impression occurs.

Site and Software Development Costs

We capitalize certain external costs and internal labor-related costs, including equity based compensation, associated with 

the development of our sites and internal-use software products after the preliminary project stage is complete and until the 
software is ready for its intended use. Costs incurred after the software is ready for use are charged to operating expenses as 
incurred. Abandoned projects previously capitalized are charged to operating expenses in the period of abandonment. The 
Company expenses costs to manage, monitor, and operate the Company's sites, except upgrade and enhancements that provide 
additional functionality, which are capitalized. Capitalized software costs are included in "Property and equipment, net" in our 
consolidated balance sheets and are amortized over a two-year period.

Leases

We generally lease office and warehouse facilities under non-cancelable, operating lease agreements. We establish assets 
and liabilities for the estimated construction costs incurred under certain lease arrangements where we are considered the owner 
for accounting purposes only, or build-to-suit leases, to the extent we are involved in the construction of structural improvements 
or take construction risk prior to commencement of a lease. Upon occupancy of facilities under build-to-suit leases, we assess 
whether these arrangements qualify for sales recognition under the sale-leaseback accounting guidance. If we continue to be the 
deemed owner, the facilities are accounted for as financing leases.

If we do not meet the sale-leaseback criteria for derecognition of the building asset and liability, the financing obligation 

and corresponding building asset are recorded in "Lease financing obligation, net of current portion" and "Property and 
equipment, net," respectively, within our consolidated balance sheets. The monthly rent payments made to the lessor under the 
lease agreement are recorded in our financial statements as land lease expense and principal and interest on the financing 
obligation. Interest expense on the lease financing obligation reflects the portion of the Company's monthly lease payments that is 
allocated to interest expense and is recorded in Interest (expense) income, net in our consolidated statements of operations. The 
building asset is depreciated over its useful life during the lease period. 

Stock-Based Compensation

We account for equity-based compensation awards in accordance with Accounting Standards Codification ("ASC") 
Topic 718, Compensation—Stock Compensation ("ASC 718"). ASC 718 requires all equity-based payments to employees to be 
recognized as expense in the statements of operations based on their grant date fair values. The Company has granted stock 
options, restricted shares and restricted stock units. The Company only granted restricted stock units to employees in the year 
ended December 31, 2017. Restricted stock unit values are determined based on the quoted market price of our Class A common 
stock on the date of grant. The Company accounts for equity awards to non-employees in accordance with Financial Accounting 
Standards Board ("FASB") ASC Topic 505-50, Equity-Based Payments to Non-Employees, which requires the fair value of an 
award to non-employees be remeasured at fair value as the award vests.

Inventory

Inventories consisting of finished goods are stated at the lower of cost or market, determined by the first-in, first-out (FIFO) 

method, and consist of merchandise for resale. This valuation requires us to make judgments based on currently-available 
information about the likely method of disposition, such as through sales to individual customers, liquidations, and expected 
recoverable values of each disposition category.

Recent Accounting Pronouncements

For information about recent accounting pronouncements, see Note 2, Summary of Significant Accounting Policies, in the 

Notes to the Consolidated Financial Statements included in Part II, Item 8, Financial Statements and Supplementary Data, of this 
Annual Report on Form 10-K. 

Item 7A.  Quantitative and Qualitative Disclosure About Market Risk

We have operations both within the U.S. and internationally, and we are exposed to market risks in the ordinary course of 

our business, including the effects of foreign currency fluctuations, interest rate changes and inflation. Information relating to 
quantitative and qualitative disclosures about these market risks is set forth below.

Interest Rate Sensitivity

Cash and cash equivalents and short-term and long-term investments were held primarily in cash deposits, certificates of 

deposit, money market funds, and corporate debt. The fair value of our cash, cash equivalents and short-term and long-term 
investments would not be significantly affected by either an increase or decrease in interest rates due mainly to the short-term 
nature of these instruments. 

Our Notes, which were issued in September 2017, carry a fixed interest rate of 0.375% per year.  Since the Notes bear 

interest at a fixed rate, we have no direct financial statement risk associated with changes in interest rates. 

Interest on the revolving line of credit incurred pursuant to the credit agreement described herein would accrue at a floating 

rate based on a formula tied to certain market rates at the time of incurrence; however, we do not expect that any change in 
prevailing interest rates will have a material impact on our results of operations.

Foreign Currency Risk

Most of our sales are denominated in U.S. dollars, and therefore, our revenue is not currently subject to significant foreign 

currency risk. Our operating expenses are denominated in the currencies of the countries in which our operations are located or in 
which net revenue is generated, and may be subject to fluctuations due to changes in foreign currency exchange rates, particularly 
changes in the British Pound, Euro, and Canadian Dollar. Fluctuations in foreign currency exchange rates may cause us to 
recognize transaction gains and losses in our statement of operations. To date, foreign currency transaction gains and losses have 
not been material to our financial statements, and we have not engaged in any foreign currency hedging transactions.

Inflation

We do not believe that inflation has had a material effect on our business, financial condition or results of operations. We 

continue to monitor the impact of inflation in order to minimize its effects through pricing strategies, productivity improvements 
and cost reductions. If our costs were to become subject to significant inflationary pressures, we may not be able to fully offset 
such higher costs through price increases. Our inability or failure to do so could harm our business, financial condition and results 
of operations.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Wayfair Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Wayfair Inc. (the Company) as of December 31, 2017 and 2016, 
the related consolidated statements of operations, comprehensive loss, shareholders’ equity (deficit) and cash flows for each of the 
three years in the period ended December 31, 2017, and the related notes (collectively referred to as the "consolidated financial 
statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the 
Company at December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period 
ended December 31, 2017, in conformity with U.S. generally accepted accounting principles. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), 
the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control-
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and 
our report dated February 26, 2018 expressed an unqualified opinion thereon.

Basis for Opinion

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

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

We have served as the Company’s auditor since 2012.

business model, the Company offers visually inspired browsing, compelling merchandising, easy product discovery and attractive 
prices for over ten million products from over 10,000 suppliers.

The consolidated financial statements and other disclosures contained in this Annual Report on Form 10-K are those of the 

Company. Prior period expenses recorded in "Merchandising, marketing and sales" and "Operations, technology, general and 
administrative" have been combined into "Selling, operations, technology, general and administrative" on the consolidated 
statements of operations to conform with current presentation.

  British Virgin Islands
Canada

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. ("GAAP") 
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure 
of contingent assets and liabilities, at the date of the financial statements, and the reported amounts of revenue and expenses 
during the reported period. On an ongoing basis, management evaluates these estimates and judgments, including those related to 
revenue recognition, capitalization of site and software development costs, stock-based compensation, and inventory. Actual 
results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity (at the date of purchase) of three 

months or less to be the equivalent of cash for the purpose of consolidated balance sheets and statements of cash flows 
presentation. Cash equivalents, which consist primarily of money market accounts, are carried at cost, which approximates market 
value.

Restricted Cash

As of December 31, 2017 and 2016, there was $5.0 million, of cash that was restricted from withdrawal and held by banks 

to guarantee the Company's letters of credit issued principally for certain vendor arrangements.

Accounts Receivable

Accounts receivable are stated net of an allowance for doubtful accounts, which is based on historical losses, existing 
economic conditions, and other information available at the consolidated balance sheets dates. Uncollectible amounts are written 
off against the allowance after all collection efforts have been exhausted.

Notes to Consolidated Financial Statements (Continued)

Short-Term Investments and Marketable Securities

Short-term investments consist of certificates of deposits and marketable securities with original maturities of greater than 

three months and maturing in less than twelve months from the balance sheet date.

The Company classifies its marketable securities as "available-for-sale" securities. Available-for-sale securities are classified 

as short-term investments and long-term investments on the consolidated balance sheets and are carried at fair value. Unrealized 
gains and losses on available-for-sale securities that are considered temporary are recorded, net of taxes, in the "Accumulated 
other comprehensive loss" caption of the Company’s consolidated balance sheets. Unrealized losses, excluding losses related to 
the credit rating of the security (credit losses), on available-for-sale securities that are considered other-than-temporary but relate 
to securities that the Company (i) does not intend to sell and (ii) will not be required to sell below cost are also recorded, net of 
taxes, in "Accumulated other comprehensive loss." Further, the Company does not believe it will be required to sell such 
securities below cost. Therefore, the only other-than-temporary losses the Company records in "Other income, net" in its 
consolidated statements of operations are related to credit losses. As of December 31, 2017 and 2016, the Company’s available-
for-sale securities consisted of investment securities. The maturities of the Company’s long-term marketable securities generally 
range from one to three years. As of December 31, 2017 and 2016, the Company's available-for-sale securities primarily consisted 
of corporate bonds and other government obligations that are priced at fair value. The cost basis of a marketable security sold is 
determined by the Company using the specific identification method. 

Fair Value of Financial Instruments

The Company's financial assets and liabilities are measured at fair value, which is defined as the price that would be 
received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement 
date (exit price). The three levels of inputs used to measure fair value are as follows:

•  Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities

•  Level 2—Unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for 
identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are 
observable or can be corroborated by observable market data for substantially the full-term of the asset or liability

•  Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value 

of the asset or liability

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of 
unobservable inputs when determining fair value. The Company measures its cash equivalents and short-term and long-term 
investments at fair value. The Company classifies its cash equivalents and restricted cash within Level 1 because the Company 
values these investments using quoted market prices. The fair value of the Company's Level 1 financial assets is based on quoted 
market prices of the identical underlying security. The Company classifies short-term and long-term investments within Level 2 
because unadjusted quoted prices for identical or similar assets in markets are not active. The Company does not have any assets 
or liabilities classified as Level 3 financial assets. Refer to Note 3, Fair Value Measurements, for additional detail.

Concentrations of Credit Risk

Financial instruments that subject the Company to credit risk consist of cash and cash equivalents, short-term and long-term 

investments, and accounts receivable. The risk with respect to cash and cash equivalents and short-term and long-term 
investments is minimized by the Company's policy of investing in financial instruments (i.e., cash equivalents) with near-term 
maturities issued by highly rated financial institutions. At times, these balances may exceed federally insured limits; however, to 
date, the Company has not incurred any losses on these investments. As of December 31, 2017 and 2016, the Company had $63.4 
million and $7.0 million, respectively, in banks located outside the U.S. The risk with respect to accounts receivable is managed 
by the Company through its policy of monitoring the creditworthiness of its customers to which it grants credit terms in the 
normal course of business.

Leases

Notes to Consolidated Financial Statements (Continued)

The Company leases office space in several countries around the world under non-cancelable lease agreements. The 
Company generally leases its office facilities under operating lease agreements. Office facilities subject to an operating lease and 
the related lease payments are not recorded on the balance sheet. The terms of certain lease agreements provide for rental 
payments on a graduated basis, however, the Company recognizes rent expense on a straight-line basis over the lease period in 
accordance with authoritative accounting guidance. Any lease incentives are recognized as reductions of rental expense on a 
straight-line basis over the term of the lease. The lease term begins on the date the Company becomes legally obligated for the 
rent payments or when it takes possession of the office space, whichever is earlier.

The Company establishes assets and liabilities for the estimated construction costs incurred under lease arrangements where 
the Company is considered the owner for accounting purposes only, or build-to-suit leases, to the extent the Company is involved 
in the construction of structural improvements or take construction risk prior to commencement of a lease. Upon occupancy of 
facilities under build-to-suit leases, the Company assesses whether these arrangements qualify for sales recognition under the 
sale-leaseback accounting guidance. If the Company continues to be the deemed owner, the facilities are accounted for as 
financing leases. Refer to Note 7, Commitments and Contingencies, for additional detail.

Foreign Currency Translation

The functional currency of the Company is the U.S. dollar, while the functional currency of certain wholly-owned 

subsidiaries outside of the U.S. is as follows:

Subsidiary
Wayfair Stores Limited
Wayfair (UK) Limited

Wayfair GmbH
Wayfair (BVI) Ltd. 

CastleGate Logistics Canada Inc.

Currency

  Euro
  Pound sterling

  Euro
  Euro

Canadian dollar

The financial statements of the Company are translated to U.S. dollars using year-end exchange rates as to assets and 
liabilities and average exchange rates as to revenue and expenses. Capital accounts are translated at their historical exchange rates 
when the capital transaction occurred. The effects of foreign currency translation are included in other comprehensive loss in the 
consolidated statements of comprehensive loss. Transaction gains and losses are included in the Company's consolidated 
statements of operations. Translation adjustments arising from the use of differing exchange rates from period to period are 
included in accumulated other comprehensive loss within total stockholders' equity (deficit).

Inventories

Inventories consisting of finished goods are stated at the lower of cost or net realizable value, determined by the first-in, 
first-out (FIFO) method, and consist of product for resale. Inventory costs consist of cost of product and inbound shipping and 
handling costs. Inventory costs also include direct and indirect labor costs, rents and depreciation expenses associated with the 
Company's fulfillment centers. Inventory valuation requires the Company to make judgments, based on currently available 
information, about the likely method of disposition, such as through sales to individual customers, liquidations, and expected 
recoverable values of each disposition category.

Goods In-Transit

Goods in-transit directly from suppliers to customers are recorded in prepaid expenses and other current assets. Risk of loss 
and the transfer of title from the supplier to the Company occur at freight on board shipping point. As of December 31, 2017 and 
2016, goods in-transit amounted to $54.5 million and $34.3 million, respectively.

Property and Equipment

Notes to Consolidated Financial Statements (Continued)

Property and equipment are stated at cost, net of depreciation and amortization. Depreciation and amortization on property 

and equipment is calculated on the straight-line method over the estimated useful lives of the assets as follows:

Class
Furniture and computer equipment
Site and software development costs
Leasehold improvements
Building (leased - Note 7)

Site and Software Development Costs

Range of Life
(In Years)
3 to 7
2

The lesser of useful life or lease term
30

The Company capitalizes certain costs associated with the development of its sites and internal-use software products after 
the preliminary project stage is complete and until the software is ready for its intended use. The capitalized costs are amortized 
over a two-year period. Costs incurred in the preliminary stages of development, after the software is ready for its intended use 
and for maintenance of internal-use software are expensed as incurred. Upgrade and enhancements are capitalized to the extent 
they will result in added functionality.

Total costs capitalized, net of accumulated amortization, totaled $45.4 million and $30.0 million as of December 31, 2017 

and 2016, respectively, and are included in property and equipment, net in the accompanying consolidated balance sheets. 
Amortization expense for the years ended December 31, 2017, 2016, and 2015 were $34.5 million, $21.6 million, and $15.3 
million, respectively. 

Long-Lived Assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances, such as service 

discontinuance or technological obsolescence, indicate that the carrying amount of the long-lived asset may not be recoverable. 
When such events occur, the Company compares the carrying amount of the asset to the undiscounted expected future cash flows 
related to the asset. If the comparison indicates that an impairment exists, the amount of the impairment is calculated as the 
difference between the excess of the carrying amount over the fair value of the asset. If a readily determinable market price does 
not exist, fair value is estimated using discounted expected cash flows attributable to the asset. For the years ended December 31, 
2017, 2016 and 2015, no impairment of long-lived assets or identifiable intangibles had been indicated.

Contingent Liabilities

The Company has certain contingent liabilities that arise in the ordinary course of business activities. The Company accrues 
for loss contingencies when losses become probable and are reasonably estimable. If the reasonable estimate of the loss is a range 
and no amount within the range is a better estimate, the minimum amount of the range is recorded as a liability. The Company 
does not accrue for contingent losses that, in its judgment, are considered to be reasonably possible, but not probable; however, it 
discloses the range of such reasonably possible losses.

Revenue Recognition

The Company generates net revenue through product sales generated primarily through the Company's five distinct sites 

and through websites  operated by third parties.

The Company recognizes revenue for product sales generated through the Company's five distinct sites and through 

websites  operated by third parties only when the following four criteria are met: (1) persuasive evidence of an arrangement 
exists; (2) delivery has occurred; (3) the selling price is fixed or determinable; and (4) collectability is reasonably assured. The 
Company recognizes net revenue from sales of its products upon delivery to the customer. As the Company ships a large volume 
of packages through multiple carriers, actual delivery dates may not always be available and as such the Company estimates 
delivery dates based on historical data. The Company records product revenue at the gross amount as the Company is the primary 
obligor with the customer and provides the primary customer service for all products sold, has latitude in establishing price and 
selecting products sold, has discretion in selecting suppliers of products sold, maintains inventory risk from shipment through 
delivery date and upon accepting returns, and has credit risk. Net revenue includes shipping costs charged to the customer and is 
recorded net of taxes collected from customers, which are remitted to governmental authorities. Cash discounts, returns and 

61

 
 
 
 
Table of Contents

Notes to Consolidated Financial Statements (Continued)

rebates are deducted from gross revenue in determining net revenue. In addition, the Company defers revenue when cash is 
collected from its customer prior to the satisfaction of the revenue recognition criteria.

The Company maintains a membership rewards program for purchases made with the Company's private label credit card, a 

Wayfair-branded credit card that can only be used at the Company's five U.S. sites. Enrolled customers earn points that may be 
redeemed for future purchases. The Company defers a portion of its revenue associated with rewards that are ultimately expected 
to be redeemed.

The Company also earns revenue through third-party advertisers that pay based on the number of advertisement related 
clicks, actions, or impressions for advertisements placed on the Company's sites. Revenue earned under these arrangements is 
included in net revenue and is recognized in the period in which the click, action, or impression occurs.

Vendor Rebates

The Company earns rebates on incentive programs with its suppliers. These rebates are earned upon shipment of goods. 

Amounts earned and due from suppliers under these rebate programs are included in other current assets on the consolidated 
balance sheets and are reflected as a reduction of cost of goods sold on the consolidated statements of operations. Vendor 
allowances received by the Company reduce the carrying cost of inventory and are recognized in cost of goods sold when the 
related inventory is sold.

Costs of Goods Sold

Cost of goods sold consists of the cost of product sold to customers, shipping and handling costs and shipping supplies and 
fulfillment costs. Fulfillment costs include costs incurred in operating and staffing the fulfillment centers, such as costs attributed 
to receiving, inspecting, picking, packaging and preparing customer orders for shipment. Cost of goods sold also includes direct 
and indirect labor costs, including equity-based compensation, for fulfillment center oversight, including payroll and related 
benefit costs. The Company also performs logistics services for suppliers through its CastleGate and Wayfair Delivery Network 
solutions, which are earned upon completion of preparing customer orders for shipment and are reflected as a reduction of cost of 
goods sold on the consolidated statements of operations. 

Advertising Costs

Advertising consists of direct response performance marketing costs, such as display advertising, paid search advertising, 

social media advertising, search engine optimization, comparison shopping engine advertising, television advertising, direct mail, 
catalog and print advertising. Expenditures for advertising are expensed in the period that the advertising first takes place. 
Advertising expense amounted to approximately $550.0 million, $409.1 million, and $278.2 million in the years ended 
December 31, 2017, 2016, and 2015, respectively. Included in prepaid expenses at December 31, 2017 and 2016 are 
approximately $0.6 million and $0.9 million, respectively, of prepaid advertising costs.

Merchant Processing Fees

Merchant processing fees totaling $88.7 million, $66.0 million, and $46.9 million in the years ended December 31, 2017, 

2016, and 2015, respectively, are included in customer service and merchant fees expense in the consolidated statements of 
operations. These fees are charged by third parties that provide merchant processing services for customer payments made by 
credit cards and debit cards.

Retail Partner Fees

The Company sells its products through websites  owned and operated by third-party online retailers, or retail partners. The 

Company pays a fee for sales generated through these websites  and records them as merchant processing fees and advertising 
costs. Retail partner fees included in merchant processing fees are $1.5 million, $1.9 million, and $3.5 million for the years ended 
December 31, 2017, 2016, and 2015, respectively. Retail partner fees included in advertising costs are $7.0 million, $11.0 million, 
and $20.2 million for the years ended December 31, 2017, 2016, and 2015, respectively.

Equity-Based Compensation

Notes to Consolidated Financial Statements (Continued)

The Company accounts for its equity-based compensation awards in accordance with ASC Topic 718, Compensation—
Stock Compensation ("ASC 718"). ASC 718 requires all equity-based payments to employees to be recognized as expense in the 
statements of operations based on their grant date fair values. The Company has granted stock options, restricted shares and 
restricted stock units. The Company has primarily granted restricted stock units, and to a lesser extent, restricted stock. The 
Company granted only restricted stock units to employees in the year ended December 31, 2017, 2016, and 2015. Restricted stock 
values are determined based on the quoted market price of our Class A common stock on the date of grant. The Company 
accounts for equity awards to non-employees in accordance with FASB ASC Topic 505-50, Equity-Based Payments to Non-
Employees, which requires the fair value of an award to non-employees be remeasured at fair value as the award vests. 

Income Taxes

Income taxes are accounted for under the asset and liability method. Under the asset and liability method, deferred tax assets 

and liabilities are recognized for the future tax consequences attributable to 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. The Company records valuation 
allowances to reduce deferred income tax assets to the amount that is more likely than not to be realized.  At December 31, 2017, 
we maintain a full valuation allowance against our net U.S. deferred tax asset as well as the net deferred tax asset of our Irish 
subsidiary.

The Company determines whether it is more likely than not that a tax position will be sustained upon examination. If it is 
not more likely than not that a position will be sustained, no amount of benefit attributable to the position is recognized. The tax 
benefit to be recognized of any tax position that meets the more likely than not recognition threshold is calculated as the largest 
amount that is more than 50% likely of being realized upon resolution of the contingency.

We evaluate at the end of each reporting period whether some or all of the undistributed earnings of our foreign subsidiaries 

are permanently reinvested.  Our position is based upon several factors including management's evaluation of the Company and 
its subsidiaries' financial requirements, the short term and long term operational and fiscal objectives of the Company, and the tax 
consequences associated with the repatriation of earnings.

Net Loss Per Share

The Company follows the two-class method when computing net loss per share for its two issued classes of common stock
—Class A and Class B. Basic net income (loss) per share is computed by dividing the net income (loss) by the weighted average 
number of common stock outstanding for the period. For periods in which the Company has reported net losses, diluted net loss 
per share is the same as basic net loss per share, since dilutive common stock are not assumed to have been issued if their effect is 
anti-dilutive.

Subsequent Events

The Company considers events or transactions that have occurred after the balance sheet date of December 31, 2017, but 
prior to the filing of the financial statements with the U.S. Securities and Exchange Commission, to provide additional evidence 
relative to certain estimates or to identify matters that require additional recognition or disclosure. Subsequent events have been 
evaluated through the filing of these financial statements. Refer to Note 16, Subsequent Events, for additional detail.

Recent Accounting Pronouncements

Stock Compensation

In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 
2016-09, "Compensation - Stock Compensation" ("ASU 2016-09"). This ASU revises the accounting for share-based payment 
transactions, including the income tax consequences, classification of awards as either equity or liabilities, and an option to 
recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on 
the statement of cash flows. 

The Company adopted ASU 2016-09 as of January 1, 2017 using a modified retrospective approach with the option to 
recognize gross stock compensation expense with actual forfeitures recognized as they occur, with a cumulative-effect adjustment 

63

Table of Contents

Notes to Consolidated Financial Statements (Continued)

to retained earnings recognized as of January 1, 2017 of $8.7 million. The adoption of ASU 2016-09 also requires all income tax 
adjustments to be recorded in the consolidated and condensed statements of operations.

Revenue Recognition

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers" ("ASU 2014-09"). This ASU 
is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods 
or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services.

ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017 and early adoption is permitted 
only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting 
year.

In March 2016, the FASB issued ASU No. 2016-08, "Revenue from Contracts with Customers - Principal versus Agent 

Considerations" ("ASU 2016-08"). This ASU clarifies the implementation guidance for principal versus agent considerations in 
ASU 2014-09. This ASU is effective at the same period as ASU 2014-09.

The Company expects to adopt the new revenue standard as of January 1, 2018 using the modified retrospective approach, 

with an immaterial cumulative-effect adjustment to retained earnings recognized as of January 1, 2018. The immaterial 
adjustment is primarily related to recognizing gift card and store credit breakage, to the extent there is no requirement for 
remitting balances to governmental agencies under unclaimed property laws. Other changes identified relate to the presentation of 
revenue, where certain third-party advertising arrangements will be classified as net revenue rather than a reduction in cost of 
goods sold.

Leases

In February 2016, the FASB issued ASU No. 2016-02, "Leases" ("ASU 2016-02"). This ASU revises the accounting related 

to leases by requiring lessees to recognize a lease liability and a right-of-use asset for all leases. The new lease guidance also 
simplifies the accounting for sale and leaseback transactions. This ASU is effective for annual reporting periods beginning after 
December 15, 2018 and early adoption is permitted. Management expects to adopt ASU 2016-02 for annual reporting periods 
beginning after December 15, 2018. Management is currently evaluating the impact of the adoption of this ASU on the 
Company’s consolidated financial statements, and expects it will have a material impact on our consolidated financial statements, 
primarily the consolidated balance sheets and related disclosures. 

3. Marketable Securities and Fair Value Measurements

Marketable Securities

As of December 31, 2017 and 2016, all of the Company’s marketable securities were classified as available-for-sale and 
their estimated fair values were $82.6 million and $99.7 million, respectively. The Company periodically reviews its available-
for-sale securities for other-than-temporary impairment. The Company considers factors such as the duration, severity and the 
reason for the decline in value, the potential recovery period, and its intent to sell. As of December 31, 2017 and 2016, the 
Company’s available-for-sale securities primarily consisted of corporate bonds and other government obligations that are priced at 
fair value. During the years ended December 31, 2017, 2016, and 2015, the Company did not recognize any other-than-temporary 
impairment loss. The maturities of the Company’s long-term marketable securities generally range from one to three years. The 
cost basis of a marketable security sold is determined by the Company using the specific identification method. During the years 
ended December 31, 2017, 2016, and 2015, the Company did not have any realized gains or losses.

The Company leases office and warehouse spaces under non-cancelable leases. These leases expire at various dates 
through 2029 and include discounted rental periods and fixed escalation clauses, which are amortized straight-line over the terms 
of the lease. Future minimum rental commitments under non-cancelable leases with initial or remaining terms in excess of one

Rent expense under operating leases was $45.2 million, $33.6 million, and $16.3 million in the years ended December 31, 
2017, 2016 and 2015, respectively. The Company has issued letters of credit for approximately $15.3 million and $10.6 million 
as security for these lease agreements as of December 31, 2017 and 2016, respectively.

Future lease payments have not been reduced by minimum sublease rentals of $6.5 million due to the Company in the 

future under non-cancelable subleases through 2020. 

The Company establishes assets and liabilities for the estimated construction costs incurred under lease arrangements 
where the Company is considered the owner for accounting purposes only, or build-to-suit leases, to the extent the Company is 
involved in the construction of structural improvements or takes construction risk prior to commencement of a lease. Upon 
occupancy of facilities under build-to-suit leases, the Company assesses whether these arrangements qualify for sales 
recognition under the sale-leaseback accounting guidance. If the Company continues to be the deemed owner, the facilities are 
accounted for as financing leases.

The construction of one warehouse lease arrangement was completed during the year ended December 31, 2016, and 
because the Company concluded it had a letter of credit of $1.2 million, the Company did not meet the sale-leaseback criteria for 
derecognition of the building asset and liability. The construction of two additional warehouse lease arrangements were 
completed in the year ended December 31, 2017, and because the Company concluded it had letters of credit of $0.8 million and 
$1.0 million, the Company did not meet the sale-leaseback criteria for derecognition of the building assets and liabilities. 
Accordingly, these leases were accounted for as financing obligations. The financing obligations and corresponding building 
assets of $28.9 million, $12.6 million, and $41.2 million were recorded in "Lease financing obligation, net of current portion" 
and "Property and equipment, net," respectively, in the Company’s consolidated balance sheets as of June 30, 2016, March 31, 
2017, and June 30, 2017, respectively, their respective quarters of completion.

The monthly rent payments made to the lessor under the lease agreement are recorded in the Company’s financial 
statements as land lease expense and principal and interest on the financing obligation. Interest expense on the lease financing 
obligation reflects the portion of the Company's monthly lease payments that is allocated to interest expense. For the years ended 
December 31, 2017 and 2016, land lease expense was $0.9 million and $0.1 million, respectively, and interest expense on lease 
financing obligations was $6.9 million and $1.4 million, respectively. As of December 31, 2017, future minimum commitments 

68

 
Table of Contents

related to the financing obligations were $38.8 million and $7.5 million for principal and interest, respectively, through 
December 31, 2022.

Notes to Consolidated Financial Statements (Continued)

Restricted Cash

The Company has deposited $5.0 million as collateral for letters of credit and has classified these amounts as "Other 

noncurrent assets" on its consolidated balance sheets at December 31, 2017 and 2016.

Collection of Sales or Other Similar Taxes

The Company does not collect and remit sales and use, commercial activity, VAT or similar taxes in all jurisdictions in 
which it has sales, based on the Company's belief that such taxes are not applicable or legally required.  Several states and other 
taxing jurisdictions have presented or threatened the Company with assessments, alleging that the Company is required to collect 
and remit such taxes there.  Other states, including South Dakota in a legal proceeding currently before the U.S. Supreme Court 
in which the Company is a defendant (South Dakota v. Wayfair Inc., 17-494), have requested that courts validate new laws that 
reverse existing constitutional precedent.  The Company does not believe that it is subject to such taxes, and intends to 
vigorously defend its position.  Pursuant to the South Dakota statute, the Company would not be required to withhold and remit 
sales tax until there was a verdict in favor of South Dakota which was then upheld by U.S. Supreme Court.  The statute also 
would not require the Company to pay sales tax retroactively if the Company were to lose.  At this time, the Company believes 
any losses that may arise from these assessments and claims would be immaterial; however, no assurance can be given as to the 
outcomes and the Company could be subject to significant additional tax liabilities. 

Legal Matters

In September 2016, a putative class action complaint was filed against the Company in the Superior Court of the province 

of Quebec (Naomi Zouzout v. Wayfair LLC, Case No. PQ 500-06-000809-166) by an individual on behalf of herself and on 
behalf of all other similarly situated individuals alleging violations of various Canadian consumer protection statutes. Among 
other remedies, this lawsuit seeks compensatory and punitive money damages, costs, and various fees. In June 2017, the 
Company entered into a settlement of the litigation, subject to judicial approval. The settlement was approved by the court in 
February 2018 and is not expected to have a material adverse effect on the Company's results of operation or financial condition.

On January 12, 2018, the U.S. Supreme Court granted certiorari in South Dakota v Wayfair Inc., 17-494.  See Collection of 

Sales or Other Similar Taxes above.

From time to time the Company is involved in claims that arise during the ordinary course of business. Although the results 

of litigation and claims cannot be predicted with certainty, the Company does not currently believe that the outcome of any of 
these other legal matters will have a material adverse effect on the Company's results of operation or financial condition. 
Regardless of the outcome, litigation can be costly and time consuming, as it can divert management's attention from important 
business matters and initiatives, negatively impacting the Company's overall operations. In addition, the Company may also find 
itself at greater risk to outside party claims as it increases its operations in jurisdictions where the laws with respect to the 
potential liability of online retailers are uncertain, unfavorable, or unclear.

8. Employee Benefit Plans

The Company has a defined-contribution, incentive savings plan pursuant to Section 401(k) of the Internal Revenue Code. 
The plan covers all full-time employees who have reached the age of 21 years. Employees may elect to defer compensation up to 
a dollar limit (as allowable by the Internal Revenue Code), of which up to 4% of an employee's salary will be matched by the 
Company. The amounts deferred by the employee and the matching amounts contributed by the Company both vest immediately. 
The amount expensed under the plan totaled approximately $9.0 million, $6.3 million, and $3.3 million in the years ended 
December 31, 2017, 2016 and 2015, respectively.

9. Equity-Based Compensation

The board of directors of the Company (the "Board") adopted the 2014 Incentive Award Plan ("2014 Plan") to grant cash 
and equity incentive awards to eligible participants in order to attract, motivate and retain talent. The 2014 Plan is administered by 
the Board with respect to awards to non-employee directors and by the compensation committee of the Board with respect to 
other participants and provides for the issuance of stock options, SARs, restricted stock, restricted stock units ("RSUs"), 
performance shares, stock payments, cash payments, dividend awards and other incentives. Prior to the adoption of the 2014 Plan, 
Wayfair LLC issued certain equity awards pursuant to the Wayfair LLC Amended and Restated Common Unit Plan (the "2010 
Plan"), which was administered by the board of directors of Wayfair LLC. Awards issued under the 2010 Plan that remain 
outstanding currently represent Class A or Class B common stock of the Company.

Notes to Consolidated Financial Statements (Continued)

8,603,066 shares of Class A common stock were initially available for issuance under awards granted pursuant to the 2014 
Plan. The 2014 Plan also contains an evergreen provision whereby the shares available for future grant are increased on the first 
day of each calendar year beginning January 1, 2016 and ending on and including January 1, 2024. As of January 1, 2018, 
8,016,850 shares of Class A common stock were available for future grant under the 2014 Plan. Shares or RSUs forfeited, 
withheld for minimum statutory tax obligations, and unexercised stock option lapses from the 2010 and 2014 Plans are available 
for future grant under the 2014 Plan. 

The Company adopted ASU 2016-09 as of January 1, 2017. For additional information, refer to Note 2, Summary of

10. Stockholders' Equity (Deficit)

Preferred Stock

The Company authorized 10,000,000 shares of undesignated preferred stock, $0.001 par value per share, for future 

issuance. As of December 31, 2017, the Company had no shares of undesignated preferred stock issued or outstanding.

Common Stock

The Company authorized 500,000,000 shares of Class A common stock, $0.001 par value per share, and 164,000,000 shares 

of Class B common stock, $0.001 par value per share, of which 57,398,983 and 49,945,202 shares of Class A common stock and 
30,809,627 and 35,885,692 shares of Class B common stock were outstanding as of December 31, 2017 and 2016, respectively. 
The rights of the holders of Class A common stock and Class B common stock are identical, except with respect to voting and 
conversion rights. Each share of Class A common stock is entitled to one vote per share and each share of Class B common stock 
is entitled to ten votes per share. Each share of Class B common stock may be converted into one share of Class A common stock 
at the option of its holder and will be automatically converted into one share of Class A common stock upon transfer thereof, 
subject to certain exceptions. In addition, upon the date on which the outstanding shares of Class B common stock represent less 
than 10% of the aggregate number of shares of the then outstanding Class A common stock and Class B common stock, or in the 
event of the affirmative vote or written consent of holders of at least 66 2/3% of the outstanding shares of Class B common stock, 
all outstanding shares of Class B common stock shall convert automatically into Class A common stock. Subject to preferences 
that may apply to any shares of preferred stock outstanding at the time, the holders of common stock are entitled to receive 
dividends out of funds legally available if the Board, in its discretion, determines to issue dividends and then only at the times and 
in the amounts that the Board may determine. Since the Company's initial public offering through December 31, 2017, 48,161,343 
shares of Class B common stock were converted to Class A common stock.

11. Segment and Geographic Information

Operating segments are defined as components of an enterprise for which separate financial information is available that is 

evaluated on a regular basis by the Chief Operating Decision Maker ("CODM") in deciding how to allocate resources to an 
individual segment and in assessing performance. The Company’s CODM is its Chief Executive Officer. 

The Company's operating and reportable segments are U.S. and International. These segments reflect the way the CODM 

allocates resources and evaluates financial performance, which is based upon each segment's Adjusted EBITDA. Adjusted 
EBITDA is defined as loss before depreciation and amortization, equity-based compensation and related taxes, interest and other 
income and expense, provision for income taxes, and non-recurring items. These charges are excluded from evaluation of 
segment performance because it facilitates reportable segment performance comparisons on a period-to-period basis. The 
accounting policies of the segments are the same as those described in Note 2, Summary of Significant Accounting Policies.

The Company allocates certain operating expenses to the operating and reportable segments, including "Customer service 

and merchant fees" and "Selling, operations, technology, general and administrative" based on the usage and relative 
contribution provided to the segments. It excludes from the allocations certain operating expense lines, including "Depreciation 
and amortization, "Equity based compensation and related taxes," "Interest (expense) income, net," "Other income, net," and 
"Provision for income taxes." There are no revenue transactions between the Company's reportable segments. 

U.S.

The U.S. segment primarily consists of amounts earned through product sales through the Company's five distinct sites in 

the U.S. and through websites  operated by third parties in the U.S.

International

The International segment primarily consists of amounts earned through product sales through the Company's international 

sites.

identification of this information for purposes of segment disclosure is impractical, as it is not readily available and the cost to 
develop it would be excessive. No individual country outside of the U.S. provided greater than 10% of total revenue.

We recorded an income tax expense of $0.5 million, representing an effective tax rate of zero. The effective tax rate differs 

from the U.S. statutory rate of 35% primarily as a result of the losses generated in the U.S. and certain foreign subsidiaries that 
have a valuation allowance and therefore cannot be benefited, as well as excess tax deductions related to equity-based 
compensation and the effects of U.S. Tax Reform.

The valuation allowance increased by $55.2 million during 2017. The increase in valuation allowance is the result of 

establishing a valuation allowance against the current year operating losses of our U.S. and Irish entities, the adoption of ASU 
2016-09 which resulted in an increase to the net operating loss and stock compensation deferred tax assets above, partially offset 
by a decrease in valuation allowance as a result of the U.S. federal tax rate reduction enacted during the fourth quarter of 2017 
and a reduction in valuation allowance associated with the net deferred tax liability recorded related to the Company’s convertible 
debt issuance.

In determining the need for a valuation allowance, the Company has given consideration to the cumulative book income and 

loss positions of each of its entities as well as its worldwide cumulative loss position. The Company has assessed, on a 
jurisdictional basis, the available means of recovering deferred tax assets, including the ability to carry-back net operating losses, 
the existence of reversing temporary differences, the availability of tax planning strategies and available sources of future taxable 
income. At December 31, 2017, we maintain a full valuation allowance against the net deferred tax assets of our U.S. and Irish 
entities. We believe we are able to support the deferred tax assets recognized as of the end of the year in other foreign jurisdictions 
based on all of the available evidence.

As of December 31, 2017, the Company had federal net operating loss carryforwards available to offset future federal 

taxable income of $420.5 million. 

In addition, the Company had state net operating loss carryforwards available in the amount of  $397.2 million which are 

available to offset future state taxable income. 

75

 
 
 
 
 
 
Table of Contents

Notes to Consolidated Financial Statements (Continued)

The federal net operating loss carryforwards begin to expire in the year ending December 31, 2034. The state net operating 

loss carryforwards begin to expire in the year ending December 31, 2022.

The Company's ability to utilize these federal and state net operating loss carry-forwards may be limited in the future if the 
Company experiences an ownership change pursuant to Internal Revenue Code Section 382. An ownership change occurs when 
the ownership percentages of 5% or greater stockholders change by more than 50% over a three-year period.

The Company also had foreign net operating loss carry-forwards available to offset future foreign income of $270.3 million. 

The foreign net operating loss carryforwards do not expire.

As of January 1, 2017 the Company adopted ASU 2016-09, Improvements to Employee Share-Based Payment Accounting 

(ASU 2016-09).  In accordance with ASU 2016-09, previously unrecognized excess tax benefits are recognized on a modified 
retrospective basis.  On January 1, 2017, the Company recorded a $44.1 million deferred tax asset related to unrecognized excess 
tax benefits with an offsetting adjustment to valuation allowance.  In addition, the Company recorded a $3.3 million increase to its 
equity based compensation deferred tax asset with an offsetting adjustment to valuation allowance as a result in the impact of 
accounting for forfeitures as incurred.

As of December 31, 2017, the Company has not provided for U.S. deferred income taxes on undistributed earnings of its 

foreign subsidiaries of approximately $3.3 million since these earnings are deemed to be indefinitely reinvested. Upon 
distribution of those earnings in the form of dividends or otherwise, the Company could be subject to income taxes as well as 
withholding taxes. The amount of taxes attributable to the undistributed earnings is not practicably determinable.

The Company establishes reserves for uncertain tax positions based on management's assessment of exposures associated 

with tax positions taken on tax return filings. The tax reserves are analyzed periodically and adjustments are made as events occur 
to warrant adjustment to the reserve. Reserves for uncertain tax positions as of December 31, 2017 and 2016 are not material and 
would not impact the effective tax rate if recognized as a result of the valuation allowance maintained against our net deferred tax 
assets.

The Company's policy is to recognize interest and penalties related to unrecognized tax benefits as a component of income 
tax expense. Related to the unrecognized tax benefits noted above, the Company did not accrue any penalties and interest during 
2017, 2016, and 2015, respectively, because it believes that such additional interest and penalties would be immaterial. 

The Company's tax jurisdictions include the U.S., the UK, Germany, Ireland, Canada and the British Virgin Islands. The 
statute of limitations with respect to the Company's U.S. federal income taxes has expired for years prior to 2014. The relevant 
state statutes vary. The statute of limitations with respect to the Company's foreign income taxes varies, but has expired for years 
prior to 2012.  However, preceding years remain open to examination by U.S. federal and state and foreign taxing authorities to 
the extent of future utilization of net operating losses generated in each preceding year.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the "Act") was signed into law making significant changes to 
the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for 
tax years beginning after December 31, 2017, the transition of U.S international taxation from a worldwide tax system to a 
territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative deferred foreign earnings as 
of December 31, 2017. On December 22, 2017, Staff Accounting Bulletin No. 118 ("SAB 118") was issued which directs 
taxpayers to consider the impact of the Act as "provisional" when a registrant does not have the necessary information available, 
prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of 
the Act.  As of December 31, 2017, the Company had not completed its accounting for the tax effects of enactment of the Act, 
however, as described below, the Company made provisional estimates of the effects of the Act on its existing deferred tax 
balances and the one-time transition tax. The Act did not have a significant impact on the Company’s consolidated financial 
statements for the year ended December 31, 2017 as a result of the valuation allowance maintained against the Company’s U.S. 
deferred tax assets.  However, the Company’s provisional estimate associated with the reduction in the U.S. federal corporate tax 
rate from 35% to 21% impacted the change in valuation allowance and change in tax rate component of the Company’s effective 
tax rate reconciliation as well as its ending deferred tax assets, deferred tax liabilities and valuation allowance in the deferred tax 
footnote disclosure.  The Company has an accumulated deficit from its foreign operations and does not have a transition tax 
associated with deferred foreign earnings related to the Act.  The ultimate impact of the Act may differ from these provisional 
amounts, possibly materially, due to, among other things, additional analysis, changes in interpretations and assumptions the 
Company has made and additional regulatory guidance that may be issued. The Company’s accounting treatment is expected to be 
complete in the fourth quarter of 2018.

13. Credit Agreement

Notes to Consolidated Financial Statements (Continued)

On February 22, 2017, the Company entered into a $40 million credit card program and a credit agreement consisting of a 

$100 million secured revolving credit facility (the "Revolver") with Citibank, N.A. ("Citibank"). The Citibank credit facility 
replaced the Company's existing credit facility with Bank of America, N.A. ("Bank of America"), which was terminated on 
February 22, 2017 as described below. On September 11, 2017, the Citibank credit agreement was amended with a new letter of 
credit sublimit ($25 million) and to make clarifying edits to the mandatory prepayment provisions of the credit agreement.

The Citibank Revolver has a $25 million letter of credit sublimit and a $10 million swing line sublimit, and a final maturity 
date of February 21, 2020. Wayfair LLC is the borrower (the "Borrower") under the Citibank credit agreement. Subject to certain 
conditions, the Borrower has the right to increase the Revolver by $25 million. Borrowings under the Revolver will bear interest 
through maturity at a variable rate based upon, at the Borrower’s option, either the Eurodollar rate or the base rate (which is the 
highest of (x) Citibank's prime rate, (y) one-half of 1.00% in excess of the federal funds effective rate, and (z) 1.00% in excess of 
the one-month Eurodollar rate), plus, in each case an applicable margin. From closing until September 30, 2019, the applicable 
margin for Eurodollar rate loans is 1.75% per annum and the applicable margin for base rate loans is 0.75% per annum. After 
September 30, 2019, the applicable margin is subject to specified changes depending on the applicable consolidated leverage 
ratio. Any amounts outstanding under the Revolver are due at maturity. In addition, subject to the terms and conditions set forth in 
the credit agreement, the Borrower is required to make certain mandatory prepayments prior to maturity.

The Citibank credit agreement contains affirmative and negative covenants customarily applicable to senior secured credit 

facilities, including covenants that, among other things, will limit or restrict the ability of the Company and its subsidiaries, 
subject to negotiated exceptions, to incur additional indebtedness and additional liens on their assets, engage in mergers or 
acquisitions or dispose of assets, pay dividends or make other distributions, voluntarily prepay other indebtedness, enter into 
transactions with affiliated persons, make investments, and change the nature of their businesses. In addition, the Citibank credit 
agreement requires the Company to maintain certain financial ratios. As of December 31, 2017, the Company was in compliance 
with its covenants under the Revolver.

The Company previously had a credit agreement with Bank of America, which was replaced by the Citibank credit 

agreement on February 22, 2017. The Bank of America credit agreement provided the Company with a $20 million revolving line 
of credit to support direct borrowings and letters of credit, provided that a maximum of $5 million could be applied to direct 
borrowings under the revolving line of credit, plus an additional $45 million credit card program (which the Company continued 
to utilize on a transitional basis until September 30, 2017), for a maximum aggregate commitment of $65 million. Subject to the 
terms and conditions of the Bank of America credit agreement, advances under the line of credit, if any, would bear interest at the 
LIBOR rate, plus 1.75%. The Bank of America credit agreement also required the Company to maintain certain covenants, 
including debt service coverage, tangible net worth and unencumbered liquid assets.

The Company did not borrow any amounts under the Revolver or the Bank of America credit agreement during the years 

ended December 31, 2017 and 2016.

14. Convertible Debt

On September 15, 2017, the Company issued $431.25 million aggregate principal amount of 0.375% Convertible Senior 
Notes due 2022 (the "Notes"), which includes the exercise in full of the $56.25 million over-allotment option, to Citigroup Global 
Markets Inc. and Goldman Sachs & Co. LLC as the initial purchasers of the Notes (the "Initial Purchasers").

The net proceeds from the sale of the Notes were approximately $420.4 million, after deducting the Initial Purchasers’ 
discounts and the estimated offering expenses payable by the Company. The Company used approximately $44.2 million of the 
net proceeds from the offering to pay the cost of the capped call transactions, as further described below, with three financial 
institutions (the "Option Counterparties"). The Company intends to use the remainder of the net proceeds for working capital and 
general corporate purposes.

The Notes were issued pursuant to an indenture, dated September 15, 2017 (the "Indenture"), between the Company and 

U.S. Bank National Association, as trustee. The Company will pay interest on the Notes semiannually in arrears at a rate 
of 0.375% per annum on March 1 and September 1 of each year commencing on March 1, 2018. The Notes are convertible based 
upon an initial conversion rate of 9.61 shares of the Company’s Class A common stock per $1,000 principal amount of Notes 
(equivalent to a conversion price of approximately $104.06 per share of the Company’s Class A common stock). The conversion 
rate will be subject to adjustment upon the occurrence of certain specified events, including certain distributions and dividends to 
all or substantially all of the holders of the Company’s Class A common stock, but will not be adjusted for accrued and unpaid 

77

Table of Contents

Notes to Consolidated Financial Statements (Continued)

interest. The Company will settle any conversions of the Notes in cash, shares of the Company’s Class A common stock or a 
combination thereof, with the form of consideration determined at the Company’s election.

The Notes will mature on September 1, 2022, unless earlier purchased, redeemed or converted. Prior to June 1, 2022, 
holders may convert all or a portion of their Notes only under the following circumstances: (1) during any calendar quarter 
commencing after the calendar quarter ending on December 31, 2017 (and only during such calendar quarter), if the last reported 
sale price of the Company’s Class A common stock for at least 20 trading days (whether or not consecutive) during a period 
of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is 
greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the 5 business day period after 
any 10 consecutive trading day period (the "measurement period") in which the trading price per $1,000 principal amount of 
Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the 
Company’s Class A common stock and the conversion rate on each such trading day; (3) with respect to any Notes called for 
redemption by the Company, at any time prior to the close of business on the second scheduled trading day immediately 
preceding the redemption date; or (4) upon the occurrence of specified corporate events. On and after June 1, 2022 until the close 
of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their Notes at any 
time, regardless of the foregoing circumstances. 

The Company may not redeem the Notes prior to September 8, 2020. On or after September 8, 2020, the Company may 

redeem for cash all or part of the Notes if the last reported sale price of the Company’s Class A common stock equals or 
exceeds 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including at 
least one of the five trading days immediately preceding the date on which the Company provides notice of redemption, during 
any 30 consecutive trading days ending on, and including the trading day immediately preceding the date on which the Company 
provides notice of the redemption. The redemption price will be 100% of the principal amount of the Notes to be redeemed, plus 
accrued and unpaid interest, if any.

Upon the occurrence of a fundamental change (as defined in the Indenture), holders may require the Company to repurchase 

all or a portion of their Notes for cash at a price equal to 100% of the principal amount of the Notes to be repurchased plus any 
accrued but unpaid interest to, but excluding, the fundamental change repurchase date.

Holders of Notes who convert their Notes in connection with a notice of a redemption or a make-whole fundamental change 

(each as defined in the Indenture) may be entitled to a premium in the form of an increase in the conversion rate of the Notes.

The Indenture contains customary terms and covenants, including that upon certain events of default occurring and 

continuing, either the Trustee or the holders of not less than 25% in aggregate principal amount of the Notes then outstanding may 
declare the entire principal amount of all the Notes plus accrued interest, if any, to be immediately due and payable. 

The Notes are general unsecured obligations of the Company. The Notes rank senior in right of payment to any of the 
Company’s future indebtedness that is expressly subordinated in right of payment to the Notes; rank equal in right of payment to 
the Company’s existing and future unsecured indebtedness that is not so subordinated; are effectively subordinated in right of 
payment to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and are 
structurally subordinated to all existing and future indebtedness and liabilities of the Company’s subsidiaries.

In accounting for the issuance of the Notes, the Company separated the Notes into liability and equity components. The 
carrying amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an 
associated convertible feature. The carrying amount of the equity component, representing the conversion option, which does not 
meet the criteria for separate accounting as a derivative as it is indexed to the Company's own stock, was determined by deducting 
the fair value of the liability component from the par value of the Notes. The difference between the principal amount of the Notes 
and the liability component represents the debt discount, which is recorded as a direct deduction from the related debt liability in 
the consolidated and condensed balance sheet and amortized to interest expense using the effective interest method over the term 
of the Notes. The equity component of the Notes of approximately $95.8 million is included in additional paid-in capital in the 
consolidated and condensed balance sheet and is not remeasured as long as it continues to meet the conditions for equity 
classification. The Company allocated transaction costs related to the Notes using the same proportions as the proceeds from the 
Notes. Transaction costs attributable to the liability component were recorded as a direct deduction from the related debt liability 
in the consolidated and condensed balance sheet and amortized to interest expense over the term of the Notes, and transaction 
costs attributable to the equity component were netted with the equity component in shareholders’ equity.

Interest expense related to the Notes for the year ended December 31, 2017 was $5.8 million, which is also comprised of the 

amortization of debt discount and debt issuance costs and the contractual coupon interest.

Notes to Consolidated Financial Statements (Continued)

The estimated fair value of the Notes was $452.5 million as of December 31, 2017. The estimated fair value of the Notes 

was determined through consideration of quoted market prices. The fair value is classified as Level 2, as defined in Note 
3, Marketable Securities and Fair Value Measurements.

On September 11, 2017, the Company entered into privately negotiated capped call transactions (the "Base Capped Call 
Transactions") with the Option Counterparties and, in connection with the exercise in full of the over-allotment option by the 
Initial Purchasers, on September 14, 2017 entered into additional capped call transactions (such additional capped call 
transactions, the "Additional Capped Call Transactions" and, together with the Base Capped Call Transactions, the "Capped Call 
Transactions") with the Option Counterparties. The Capped Call Transactions are expected generally to reduce the potential 
dilution and/or offset the cash payments the Company is required to make in excess of the principal amount of the Notes upon 
conversion of the Notes in the event that the market price per share of the Company’s Class A common stock is greater than the 
strike price of the Capped Call Transactions (which initially corresponds to the initial conversion price of the Notes and is subject 
to certain adjustments under the terms of the Capped Call Transactions), with such reduction and/or offset subject to a cap based 
on the cap price of the Capped Call Transactions. The Capped Call Transactions have an initial cap price of $154.16 per share of 
the Company’s Class A common stock, which represents a premium of 100% over the last reported sale price of the Company’s 
Class A common stock on September 11, 2017, and is subject to certain adjustments under the terms of the Capped Call 
Transactions. Collectively, the Capped Call Transactions cover, initially, the number of shares of the Company’s Class A common 
stock underlying the Notes, subject to anti-dilution adjustments substantially similar to those applicable to the Notes.

The Capped Call Transactions are separate transactions, in each case, entered into by the Company with the Option 
Counterparties, and are not part of the terms of the Notes and will not affect any holder’s rights under the Notes. Holders of the 
Notes will not have any rights with respect to the Capped Call Transactions. The Capped Call Transactions do not meet the 
criteria for separate accounting as a derivative as they are indexed to the Company's stock. The premiums paid for the Capped 
Call Transactions have been included as a net reduction to additional paid-in capital within shareholders’ equity.

15. Net Loss per Share

Basic and diluted net loss per share is presented using the two-class method required for participating securities: Class A and 

Class B common stock. The rights of the holders of Class A and Class B common stock are identical, except with respect to 
voting and conversion. For more information on the rights of Class A and Class B common stockholders, see Note 
10, Stockholders' Equity (Deficit).

Basic net loss per share is computed using the weighted-average number of shares of common stock outstanding during the 

period. Diluted net loss per share is computed using the weighted-average number of shares of common stock and, if dilutive, 
common stock equivalents outstanding during the period. The Company's common stock equivalents consist of shares issuable 
upon the release of restricted stock units, and to a lesser extent, the incremental shares of common stock issuable upon the 
exercise of stock options and unvested restricted stock. The dilutive effect of these common stock equivalents is reflected in 
diluted earnings per share by application of the treasury stock method. The Company's basic and diluted net loss per share are the 
same because the Company has generated net loss and common stock equivalents are excluded from diluted net loss per share 
because they have an antidilutive impact.

The Company allocates undistributed earnings between the classes on a one-to-one basis when computing net loss per 

share. As a result, basic and diluted net loss per Class A and Class B shares are equivalent.

The following table presents the calculation of basic and diluted net loss per share (in thousands, except per share data):

Dilutive common stock equivalents, representing potentially dilutive common stock options, restricted stock and restricted 

stock units, of 7.0 million, 7.3 million, and 5.9 million for 2017, 2016, and 2015, respectively, were excluded from diluted 
earnings per share calculations for these periods because of their anti-dilutive effect. Furthermore, the shares of Class A common

Table of Contents

Notes to Consolidated Financial Statements (Continued)

stock that would be issuable if the Company elects to settle the Notes in shares were excluded from the diluted earnings per share 
calculation (using the if-converted method) for the year ended December 31, 2017 because their effect would have been anti-
dilutive. 

The Company may settle the conversions of the Notes in cash, shares of the Company's Class A common stock or any 

combination thereof at its election. The number of shares of the Company's Class A common stock issuable at the conversion 
price of $104.06 per share is expected to be 4.1 million shares, however the Capped Call Transactions are expected generally to 
reduce the potential dilution of the Company's Class A common stock upon any conversion of Notes and/or offset the cash 
payments the Company is required to make in excess of the principal amount of the Notes. Under the Capped Call Transactions, 
the number of shares of Class A common stock issuable at the conversion price of $154.16 is expected to be 2.8 million shares. 
For more information on the Notes and the Capped Call Transactions, see Note 14, Convertible Debt.

16. Subsequent Events

Stock Repurchase Program

On February 22, 2018, the Company announced that the Board authorized the repurchase of up to $200 million of the 
Company’s Class A common stock. This repurchase program has no expiration but may be suspended or terminated by the Board 
at any time.  Under the repurchase program, the Company is authorized to repurchase, from time to time, outstanding shares of its 
Class A common stock in the open market, through privately negotiated transactions, or otherwise, including pursuant to a Rule 
10b5-1 plan.

The actual timing, number and value of shares repurchased will be determined by the Company in its discretion and will 

depend on a number of factors, including market conditions, applicable legal requirements, the Company’s capital needs and 
whether there is a better alternative use of capital. The Company has no obligation to repurchase any amount of its Class A 
common stock under the program.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer ("CEO") and chief financial officer ("CFO"), 

evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the 
Securities Exchange Act of 1934, as amended, or the Exchange Act) as of December 31, 2017. Based on such evaluation, our 
CEO and CFO have concluded that, as of December 31, 2017, our disclosure controls and procedures are effective in ensuring 
that (a) the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, 
processed, summarized, and reported within the time periods specified in the SEC's rules and forms, and (b) such information is 
accumulated and communicated to our management, including our principal executive officer and principal financial officer, as 
appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting identified in connection with the evaluation required 
by Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the quarter ended December 31, 2017 that materially affected, or are 
reasonably likely to materially affect, our internal control over financial reporting.

Management's Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as 
defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Our management conducted an evaluation of the effectiveness 
of our internal control over financial reporting based on the framework in Internal Control-Integrated Framework issued by the 
Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on this evaluation, management 
concluded that our internal control over financial reporting was effective as of December 31, 2017 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. Management reviewed the results of its assessment with our Audit 
Committee. The effectiveness of our internal control over financial reporting as of December 31, 2017 has been audited by Ernst 
& Young LLP, an independent registered public accounting firm, as stated in its report which is included immediately following 
Item 9A. Controls and Procedures, in this Annual Report on Form 10-K.

Limitations on Disclosure Controls and Procedures and Internal Control over Financial Reporting

Our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable 

assurance of achieving their objectives as specified above. Management does not expect, however, that our disclosure controls 
and procedures or our internal control over financial reporting will prevent or detect all error and fraud. Any control system, no 
matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, 
assurance that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due 
to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Wayfair Inc.

Opinion on Internal Control over Financial Reporting

We have audited Wayfair Inc.’s internal control over financial reporting as of December 31, 2017, based on criteria established in 
Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 
framework) (the COSO criteria). In our opinion, Wayfair Inc. (the Company) maintained, in all material respects, effective internal 
control over financial reporting as of December 31, 2017, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), 
the consolidated balance sheets of the Company as of December 31, 2017 and 2016, the related consolidated statements of operations, 
comprehensive loss, shareholders’ equity (deficit) and cash flows for each of the three years in the period ended December 31, 2017, 
and the related notes and our report dated February 26, 2018 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment 
of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual 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.
