Item 1. Business

Overview

We are a global technology company that empowers ad buyers by providing a self-service omnichannel software platform that enables our clients to purchase and manage data-driven digital advertising campaigns. Our platform allows clients to manage integrated advertising campaigns across various advertising channels and formats, including connected TV (CTV), mobile, video, audio, display, social and native, on a multitude of devices, including smart TVs, computers, and various mobile devices including phones and tablets.

We commercially launched our platform in 2011 targeting display advertising. We have since extended our platform to address additional advertising formats, and in 2017, approximately 62% of gross spend on our platform was for mobile, video, audio, social, and native.

Our clients are the advertising agencies and other service providers for advertisers, with whom we enter into ongoing master services agreements, or MSAs. We generate revenue by charging our clients a platform fee based on a percentage of a client’s total spend on advertising, data and other features through our platform.

The Trade Desk, Inc. is a Delaware corporation established in 2009, headquartered in Ventura, California.

Our Industry

We believe that several trends in the advertising industry, happening in parallel, are driving a shift to programmatic advertising – the selling and buying of advertising inventory electronically.

Some of the key industry trends are:

Media is Becoming Digital. Media is increasingly becoming digital as a result of advances in technology and changes in consumer behavior. This shift has enabled unprecedented options for advertisers to target and measure their advertising campaigns across nearly every media channel and device. The digital advertising market is a significant and growing part of the total advertising market. According to International Data Corporation, or IDC, global advertising spend was estimated to be approximately $672 billion in 2017 and is expected to grow to $764 billion in 2021, a compound annual growth rate of 3.3%. Also, according to IDC, global digital advertising spend was $229 billion in 2017 and is expected to grow to $360 billion in 2021, a compound annual growth rate of 11.9%. We believe that the market is evolving and that advertisers will shift more spend to digital media. Since media is becoming increasingly digital, decisions based on consumer and behavioral data are more prevalent.

Fragmentation of Audience. As digital media grows, audience fragmentation is accelerating. A growing “long tail” of websites and content presents a challenge for advertisers trying to reach a large audience. Audience fragmentation has substantially impacted TV content distribution, perhaps more than any other channel, which we believe is setting up a significant change in how TV advertising inventory is monetized. Mirroring the fragmentation occurring in content, the number of devices used by individual consumers has increased. Both of these fragmentation trends are opportunities for technology companies that can consolidate and simplify media buying options for advertisers and their agencies.

Increased Use of Data. Advances in software and hardware and the growing use of the Internet have made it possible to collect and rapidly process massive amounts of user data. Data vendors are able to collect user information across a wide range of Internet properties and connected devices, aggregate it and combine it with other data sources. This data is then made non-identifiable and available within seconds based on specific parameters and attributes. Advertisers can integrate this targeting data with their own or an agency’s proprietary data relating to client attributes, the advertisers’ own store locations and other related characteristics. Through the use of these data sources, together with real-time feedback on consumer reactions to the ads, programmatic advertising increases the value of impressions for advertisers, inventory owners and viewers who receive more relevant ads.

Automation of Ad Buying. The growing complexity of digital advertising has increased the need for automation. Technology that enables fast, accurate and cost-effective decision-making through the application of computer algorithms that use extensive data sets has become critical for the success of digital advertising campaigns. Using programmatic inventory buying tools, advertisers are able to automate their campaigns, providing them with better price discovery, on an impression-by-impression basis. As a result, advertisers are able to bid and purchase the advertising inventory they value the most, pay less for advertising inventory they do not value as much, and abstain from buying advertising inventory that does not fit their campaign parameters.

Digital Advertising Eco-System

The digital advertising eco-system is divided into buyers, sellers and marketplaces, which can be further segmented on the basis of whether participants provide services or technology. We believe that participants on the buy-side or sell-side should be advocates for their buyers or sellers, while those in the market business should act as a referee or have market-driven incentives to protect or enhance the integrity of the marketplace. We believe that there are inherent conflicts of interest when market participants serve both buyers and sellers.

What We Do

We empower ad buyers, by providing a self‑service omnichannel software platform that enables our clients to purchase and manage data‑driven digital advertising campaigns. Our platform allows clients to manage integrated advertising campaigns across various advertising channels and formats, including CTV, mobile, video, audio, display, social and native, on a multitude of devices, including smart TVs, computers, and various mobile devices including phones and tablets.

	•	We Are Exclusively Focused on the Buy-Side. We focus on buyers since they control the advertising budgets. Also, the supply of digital advertising inventory exceeds demand, and accordingly, we believe it is a buyer’s market. We also believe that by aligning our business only with buyers, we are able to avoid inherent conflicts of interest that exist when serving both the buy-side and sell-side. This focus allows us to build trust with clients, many of whom incorporate their proprietary data into our platform. That trust and ability to use their own data on our platform, without worrying about it being used by other participants, enables our clients and their advertisers to achieve better results. This trust provides us the benefit of long-term and stable relationships with our clients.

	•	We Are an Enabler, Not a Disruptor. With our platform, we enable advertising agencies and service providers. We generally do not compete with advertising agencies and refrain from directly serving advertisers who have a relationship with one of our advertising clients. Advertisers can benefit from a comprehensive solution that combines our platform with the services provided by advertising agencies.

	•	We Are Data-Driven. Our platform was founded on the principle that data-driven decisions will be the future of advertising. We built a data management platform first, before building our ad buying technology. While data from disparate third-party data providers can improve campaign performance, our clients’ success often relies largely on our ability to ingest proprietary data directly from brands and their agencies to enable intelligent decisioning that optimizes advertising campaigns. Given our independent, buy-side focused approach, and our strict protocol of carefully earmarking all client first-party data we ingest onto our data management platform, our clients trust us with their most granular and expressive data. Our technology platform enables the effective use of this granular data, which allows our clients to run more effective and precisely targeted advertising campaigns that maximize their return on advertising investments. Additionally, we are able to better optimize campaigns by using the data streams that we capture across different devices, so that data from one channel can be used to inform another. The breadth of data that we collect from a multitude of data sources across channels gives our clients a holistic view of their target audiences, enabling more effective targeting across different channels.

	•	We Do Not Arbitrage Advertising Inventory. To further align our interests with those of our clients, we do not buy advertising inventory in order to resell it to our clients for a profit. Instead, we provide our clients with a platform that allows them to manage their omnichannel advertising campaigns, on a self-serve basis with full reporting transparency. With our platform, our clients control their campaign spend and are able to access and choose from many inventory sources.

	•	We Have Ongoing Relationships with Clients. We derive substantially all of our revenue from ongoing MSAs with our clients rather than episodic insertion orders. We believe that this approach helps us strengthen our relationships with our clients and grow their use of our platform over the long term, providing us with a highly scalable business model.

	•	We Are a Clear Box, Not a Black Box. Our platform is transparent and shows our clients their costs of advertising inventory, data, our platform fee and detailed performance metrics on their advertising campaigns. Our clients directly access and execute campaigns on our platform, control all facets of inventory purchasing decisions, and receive detailed, real-time reporting on all their advertising campaigns. By providing transparent information on our platform, our clients are able to continually compare results and target their budgets to the most effective advertising inventory, data providers and channels.

	•	We Are an Open Platform. Clients can customize and build their own features on top of our platform. Clients may use our application programming interfaces, or APIs, to, for example, design their own user interface, bulk manage advertising campaigns, and link other systems including ad servers or reporting tools. As of December 31, 2017, all of our top 10 clients used our APIs and nearly half of our clients have customized our APIs. Using our APIs or by working with our engineering team, clients invest their own resources to build their own proprietary tools in areas including reporting, campaign strategy, custom algorithms or proprietary data use cases. Our open platform approach enables our advertising agency and service provider clients to provide differentiated offerings to their clients, which we believe leads to long-term relationships and increased use of our platform.

Our Platform

Our platform enables a media planner or buyer at an advertising agency to:

	•	purchase digital media programmatically on various media exchanges and sell-side platforms;

	•	acquire and use third-party data to optimize and measure digital advertising campaigns;

	•	integrate and deploy their proprietary first-party data with our platform in order to optimize campaign efficacy;

	•	monitor and manage ongoing digital advertising campaigns on a real-time basis;

	•	link digital campaigns to offline sales results or other business objectives;

	•	access other services such as our data management platform and publisher management platform marketplace; and

	•	use our user interface and APIs to build their own proprietary technology on top of our platform.

At the core of our platform is our bid-factor based architecture, which we believe has advantages over line-item based architectures that other buy-side systems use. Our bid-factor based system allows users to define desirable factors and the value associated with those factors. Based on these factors, our platform can compute in real-time the value of impressions and bid only for optimal impressions. Because of the granularity of the bid factors, users of our platform can rapidly create billions of different bid permutations with only a few clicks. This expressiveness enables better targeting, pricing and campaign results.

Our platform is useful and user-friendly based on the following:

	•	Easy to Use, Open and Customizable. Our platform provides multiple, easy-to-use automation tools that help our users focus on managing the key factors affecting their campaigns. Our platform also enables clients to integrate custom features and interfaces for their own use through our APIs.

	•	Expressive. Our platform allows clients to easily define and manage advertising campaigns with multiple targeting parameters that may result in quadrillions of permutations, which we refer to as expressiveness. We believe that expressiveness provides clients with the ability to target audiences with an extremely high level of precision and thus obtain higher returns on their advertising spend.

	•	Integrated, Omnichannel and Cross-device. Our platform provides integrated access to a wide range of omnichannel inventory and data sources, as well as third-party services such as ad servers, ad verification services and survey vendors. Our platform’s integration of these sources and services enables our clients to deploy their budgets through a wide variety of channels, media screens and formats, targeted in their desired manner, through a single platform.

Some of the key features of our platform are:

	•	Auto-Optimization. We provide auto-optimization features which allow buyers to automate their campaigns and support them with computer generated modeling and decision making. In addition, by giving clients full reporting, budgeting, and bidding transparency, clients can take control of targeting variables when desired, and apply algorithmic automation when appropriate.

	•	Advanced Reporting and Analytics Tools. We provide a comprehensive view of consumers’ interactions with the ads purchased through our platform with robust reporting of performance insights across multiple variables, such as audience characteristics, ad format, site category, website, device, creative type, and geography. Better reporting results in better learning, often leading to better campaign optimization and outcomes.

	•	Data Management. Our platform enables clients to license a broad selection of data from third-party vendors in a seamless and easy manner, allowing them to further optimize their campaigns with the most relevant data.

	•	Private Marketplace Support. For clients who wish to transact directly with individual publishers, we offer a comprehensive user interface for discovering and transacting via a wide variety of private pricing contracts. Additionally, we offer direct tags that advertisers can use when they negotiate deals with publishers through advertising agencies.

Our Technology

The core elements of our technology are:

	•	Scalable Architecture. Our platform infrastructure is hosted in 13 data centers. On average, our real-time bidding technology evaluates more than 580 billion ad opportunities per day, reaching over 430 million devices per day on a global basis. Our core bidding architecture is easily adaptable to a variety of inventory formats, allowing our platform to communicate with many different inventory sources.

	•	Predictive Models. We use the massive data captured by our platform to build predictive models around user characteristics, such as demographic, purchase intent or interest data. Data from our platform is continually fed back into these models, which enables them to improve over time as the use of our platform increases.

	•	Performance Optimization. During campaign execution, our optimization engine continually scores a variety of attributes of each impression, such as website, industry vertical or geography, for their likelihood to achieve campaign performance goals. Our bidding engine then shifts bids and budgets in real-time to deliver optimal performance. Additionally, our platform enables clients to set multiple, simultaneous optimization goals for their advertising.

	•	Real-time Analytics. Our platform continuously collects data regarding inventory availability. Real-time campaign delivery and spend totals are used to manage campaign budgets and goal caps, as well as campaign reporting. This data is fed back into our optimization engine to improve campaign performance, and into machine-learning models for user demographic predictive modeling.

Our Growth Strategy

The key elements of our long-term growth strategy include:

	•	Increase Our Share of Existing Clients’ Digital Advertising Spend. Many advertisers are moving a greater percentage of their advertising budgets to programmatic channels. We believe that this shift will provide us with the opportunity to capture a larger share of the overall advertising spend by our existing clients. Additionally, we plan to promote additional services and data to our clients, helping us grow our business.

	•	Grow Our Client Base. We have extensive relationships with many advertising agencies and service providers, and believe that, given the decentralized nature of the advertising industry, we have the opportunity to expand our relationships within these agencies and with additional agencies and service providers. We expect to continue making investments in growing our sales and client service team to support this strategy.

	•	Expand Our Omnichannel Capabilities. We believe offering clients capabilities across all media channels and devices enables advertisers to manage omnichannel campaigns and use data from each channel to inform decisions in other channels. We believe these capabilities will continue to further strengthen our relationships with our clients. We intend to continue to invest in innovation across all channels, including the integration of new inventory sources within CTV, digital radio, social and native.

	•	Extend Our Reach in CTV. Television is the largest category of advertising spend, and we believe that the future of television is in streaming media and video on demand through subscription services and connected devices. We plan to invest significant resources in technology, sales and support staff related to our CTV growth initiatives.

	•	Continue to Innovate in Technology and Data. We intend to continue to innovate in technology to improve our platform and enhance its features and functionalities. We view data as one of our key competitive advantages. We will continue to invest resources in growing our data offerings, both from third-party providers as well as our proprietary data.

	•	Expand Our International Presence. Many of our clients serve advertisers on a global basis and we intend to expand our presence outside of the United States, or U.S., to serve the needs of those advertisers in additional geographies. As we expand relationships with our existing clients, we are investing in select regions in Europe and Asia. In particular, we believe that China and Indonesia may represent substantial growth opportunities, and we are investing in developing our business in those markets.

Our Clients

Our clients consist of purchasers of programmatic advertising inventory and data. As of December 31, 2017, we had approximately 657 clients, consisting primarily of advertising agencies or groups within advertising agencies that have independent relationships with us, manage budgets independently of one-another, are based in different jurisdictions, and are served by unique Trade Desk teams. Many of these agencies are owned by holding companies, where decision-making is decentralized such that purchasing decisions are made, and relationships with advertisers are located, at the agency, local branch or division level. Our client count includes only those parties which have signed MSAs with us and have spent more than $20,000 on our platform.

If all of our individual client contractual relationships were aggregated at the holding company level, two clients would have each represented more than 10% of our gross billings in 2015, three clients would have each represented more than 10% of our gross billings in 2016, and three clients would have each represented more than 10% of our gross billings in 2017. Our contractual and billing arrangement with Omnicom Group Inc. is at the holding company level and accounted for 12% of our gross billings in 2015, 13% in 2016 and 11% in 2017. For WPP plc and Publicis Groupe, we enter into separate contracts and billing relationships with various of its individual agencies and account for them as separate clients. We do not have any contractual relationship with the holding company WPP plc or Publicis Groupe. Mindshare, which is affiliated with WPP plc, accounted for 12% of our gross billings in 2015, 11% in 2016 and 10% in 2017. VivaKi, Inc., which is affiliated with Publicis Groupe, accounted for 15% of our gross billings in 2016 and 22% in 2017.

Our clients typically enter into MSAs with us that give users constant access to our platform. The MSAs do not contain any material commitments on behalf of clients to use our platform to purchase ad inventory, data or other features. These MSAs typically have one-year terms that renew automatically for additional one-year periods, unless earlier terminated. The MSAs are typically terminable at any time upon 60 days’ notice by either party.

Our clients are loyal, as reflected by our client retention rate of over 95% in 2015, 2016 and 2017. In addition, our clients typically grow their use of our platform over time.

Our Advertising and Data Inventory Suppliers

For suppliers of programmatic advertising inventory and data, we believe that we are an important business client, as we represent one of the largest sources of buy-side demand within the digital advertising industry.

We obtain digital advertising inventory from over 70 ad exchanges, supply-side platforms, publishers and ad networks, providing us with access to a breadth of programmatic advertising inventory across computers, smartphones, audio devices and CTV. On average each day, our platform provides our clients with access to over 580 billion ad impressions per day, reaching over 430 million devices per day on a global basis.

For third-party data vendors, we believe that we represent an important distribution channel. As of December 31, 2017, we have integrated our platform with over 135 third-party data vendors whose products we make available for purchase through our platform.

Sales and Marketing

Given our self-serve business model, we focus on supporting, advising and training our clients to use our platform independently as soon as they are ready to transact.

Once a new client has access to our platform, they work closely with our client service teams as they onboard the new client and provide continuous support throughout the early campaigns. Typically, once a client has gained some initial experience, it will move to a fully self-serve model and request support as needed.

To help train our clients, suppliers and other digital media participants, we have created an e-learning program called The Trading Academy. We believe that this initiative is an important component in our strategy of enabling rapid onboarding to our platform.

Our marketing efforts are focused on increasing awareness for our brand, executing thought-leadership initiatives, supporting our sales team and generating new leads. We seek to accomplish these objectives by presenting at industry conferences, hosting client conferences, publishing white papers and research, public relations activities, social media presence and advertising campaigns.

Technology and Development

Rapid innovation is a core driver of our business success and our corporate culture. We prioritize and align our product roadmap with our clients’ needs, and we generally refresh our platform on a weekly basis. Our development teams are intentionally lean and nimble in nature, providing for transparency and accountability.

We expect technology and development expense to increase as we continue to invest in the development of our platform to support additional features and functions, increase the number of advertising and data inventory suppliers and ramp up the volume of advertising spending on our platform. We also intend to invest in technology to further automate our business processes. Our technology development expense totaled $12.8 million in 2015, $27.3 million in 2016 and $52.8 million in 2017.

Seasonality

In the advertising industry, companies commonly experience seasonal fluctuations in revenue. For example, many advertisers allocate the largest portion of their budgets to the fourth quarter of the calendar year in order to coincide with increased holiday purchasing. Historically, the fourth quarter of the year reflects our highest level of advertising activity and the first quarter reflects the lowest level of such activity. We expect our revenue to continue to fluctuate based on seasonal factors that affect the advertising industry as a whole.

Our Competition

Our industry is highly competitive and fragmented. We compete with other demand-side platform providers which are mostly smaller, privately-held companies, but we also compete with divisions of large, well-established companies such as Google and Adobe. We believe that we compete primarily based on the performance, capabilities and transparency of our platform and our focus on the buy-side. We generally do not compete with advertising agencies and refrain from directly serving advertisers who have a relationship with one of our advertising agency clients. We believe that we are differentiated from our competitors in the following areas:

	•	we are an independent technology company exclusively focused on serving advertising agencies and the buy-side of our industry;

	•	our client relationships are based on master service agreements as opposed to campaign-specific insertion orders;

	•	our platform provides comprehensive access to a wide range of inventory types and third-party data vendors;

	•	our platform allows clients to build proprietary advantages by integrating custom features and interfaces for their own use through our APIs; and

	•	our technology provides highly expressive targeting.

In addition, we believe that new entrants would find it difficult to gain direct access to inventory providers, given their limited scale and the costs that additional integrations impose on inventory providers.

Our Employees and Culture

We have employees and offices around the world to serve advertisers’ desire to communicate with consumers worldwide.

Our business and our culture is anchored on four core principles:

	•	No company can effect global change without passionate forward‑thinking people as both employees and clients.

	•	By preserving an honest and transparent culture and avoiding client conflict, we can exert exponentially less effort to grow our business.

	•	We have committed to our clients and employees that we will never stop innovating.

	•	Being profitable and changing the world can co‑exist and is more likely to happen when striving for both simultaneously.

We believe we attract talented employees to our company and sophisticated ad buyers to our platform in large part because of our vision and unwavering commitment to empower the buy‑side of advertising.

As of December 31, 2017, we had 713 employees, of whom 502 are in the U.S. Our team draws from a broad spectrum of backgrounds and experiences, across technology, advertising and securities trading and other areas. We foster an entrepreneurial culture so that we may remain focused and innovative over time, as we strive to serve our clients with openness, transparency and humility.

Development of International Markets

We have been increasing our focus on markets outside the U.S. to serve the global needs of our clients. We believe that the global opportunity for programmatic advertising is significant, and should continue to expand as publishers and advertisers outside the U.S. seek to adopt the benefits that programmatic advertising provides. To capitalize on this opportunity, we intend to continue investing in our presence internationally, and we expect our growth internationally to continue outpacing our domestic growth. Our growth and the success of our initiatives in newer markets will depend on the continued adoption of our platform by our existing clients, as well as new clients, in these markets. Information about our geographic gross billings is set forth in Note 12 of “Item 8. Financial Statements and Supplementary Data” in this Annual Report on Form 10-K.

Intellectual Property

The protection of our technology and intellectual property is an important component of our success. We rely on intellectual property laws, including trade secret, copyright and trademark laws in the U.S. and abroad, and use contracts, confidentiality procedures, non-disclosure agreements, employee disclosure and invention assignment agreements and other contractual rights to protect our intellectual property. We do not hold any patents because we believe our proprietary technology is best protected by keeping our technology architecture, trade secrets, and engineering roadmap private. We believe our platform is difficult to replicate and would be expensive to build. We also believe that a critical protection in digital advertising technology is the ability to execute and deliver new functionality quickly, and are continually developing new intellectual property as we innovate.

Privacy and Data Protection Legislation and Regulation

Privacy and data protection legislation and regulation play a significant role in our business. We and our clients use pseudonymous and anonymous data about Internet users on our platform to manage and execute digital advertising campaigns in a variety of ways, including delivering advertisements to Internet users based on their geographic locations, the type of device they are using, or their interests as inferred from their web browsing or app usage activity, or that clients infer from their relationships with users. We do not use this data to identify specific individuals, and we do not seek to associate this data with information that can be used to identify specific individuals. We take steps not to collect or store personally identifiable information – information that directly identifies individuals – from any source. The definition of what data is personal or identifiable, however, varies by jurisdiction and continues to evolve. As a result, our platform and business practices must be assessed regularly in each jurisdiction where we do business to avoid violating applicable legislation and regulation.

Our ability, like those of other advertising technology companies, to collect, augment, analyze, use and share data collected through cookies and similar technologies is governed by U.S. and foreign laws and regulations which change from time to time, such as those regulating the level of consumer notice and consent required before a company can employ cookies or other electronic tools to collect data about interactions with users online. In the United States, both state and federal legislation govern activities such as the collection and use of data, and privacy in the advertising technology industry has frequently been subject to review by the Federal Trade Commission, or the FTC, U.S. Congress, and individual states. Much of the federal oversight on digital advertising in the United States has come from the FTC, which has primarily relied upon Section 5 of the Federal Trade Commission Act, which prohibits companies from engaging in “unfair” or “deceptive” trade practices, including alleged violations of representations concerning privacy protections and acts that allegedly violate individuals’ privacy interests.

As our business is global, our activities are also subject to foreign legislation and regulation. In the European Union (including the European Economic Area, or EEA, countries of Iceland, Liechtenstein and Norway), or EU, separate laws and regulations (and member states’ implementations thereof) govern the protection of consumers and of electronic communications, and these laws and regulations continue to evolve. The General Data Protection Regulation, or GDPR, which was adopted by the EU in 2016 and becomes effective May 25, 2018, will generally harmonize data privacy laws across EU countries. The GDPR creates new regulations relating to the collection and use of data typically leveraged on our platform and by others in the digital advertising industry, including IP addresses, cookie identifiers, and device identifiers for advertising purposes, and enhances data protection obligations for controllers of personal data and service providers processing personal data. These enhancements will bring about significant changes in the way the advertising technology industry operates in the EU. Preparing to meet the GDPR’s requirements before it becomes effective, and maintaining compliance with the GDPR thereafter, will require significant time, resources and expense, and significant changes in our business operations.

Additionally in the EU, EU Directive 2002/58/EC (as amended by Directive 2009/136/EC), commonly referred to as the Cookie Directive, directs EU member states to ensure that accessing information on an Internet user’s computer, such as through a cookie and other similar technologies, is allowed only if the Internet user has been informed about such access, and provided consent. A replacement for the Cookie Directive is currently under discussion by EU member states to complement and bring electronic communication services in line with the GDPR and force a harmonized approach across EU member states. Although it remains under debate, recent drafts of the new ePrivacy Regulation would extend the strict opt-in marketing rules with limited exceptions to business-to-business communications, alter rules on third-party cookies, web beacons and similar technology, and significantly increase penalties for non-compliance. We cannot yet determine the impact such future laws, regulations, and standards may have on our business.

For the transfer of personal data from the EU to the U.S., we rely upon, and are currently certified under, the EU-U.S. and Swiss-U.S. Privacy Shield Frameworks. The Privacy Shield Framework, however, is facing criticism from privacy advocates in the EU and is also subject to pending legal challenges in the General Court of the Court of Justice of the European Union. Other EU mechanisms for adequate data transfer to the U.S. such as the standard contractual clauses are also being challenged in the EU courts. These challenges to the Privacy Shield and model clauses may lead to changes in the law, governmental enforcement actions, litigation, fines and penalties or adverse publicity which could have an adverse effect on our reputation and business. We may find it

necessary to establish systems to maintain personal data originating from the EU in the EU, which may involve substantial expense and may cause us to need to divert resources from other aspects of our business.

In prior years, some government regulators and privacy advocates advocated vigorously for a “Do Not Track” standard that would allow Internet users to express a preference, independent of cookie settings in their browser, not to have their online browsing activities tracked. Efforts in this direction have largely gone dormant. However, in the EU, the Article 29 Working Party, a body made up of EU national data protection authorities, recently recommended that the proposed e-Privacy Regulation require browsers to implement technical mechanisms such as the “Do Not Track” standard to give users additional control over the collection of data about their Internet activity. We do not know whether such requirement will be included in the final e-Privacy Regulation or what effect such requirement may have on our business.

We participate in several industry self-regulatory programs, mainly initiated by the Network Advertising Initiative, or NAI, the Digital Advertising Alliance, or DAA, and their international counterparts. Under such programs, in addition to other compliance obligations, we provide consumers with notice about our use of cookies and similar technologies, and our collection and use of data in connection with the delivery of targeted advertising. We also allow consumers to opt out from the use of data we collect for the delivery of targeted advertising, and we provide consumers notice regarding how to exercise such choice. We believe that this user-centric approach to addressing consumer privacy empowers consumers to make informed decisions on the use of their data.
