All statements contained in this Annual Report on Form 10-K other than statements of historical fact, including statements regarding our future results of operations and financial position, our business strategy and plans, our objectives for future operations, and the impact of the ongoing coronavirus (COVID-19) pandemic on our financial condition and results of operations are forward-looking statements. The words &#8220;believe,&#8221; &#8220;may,&#8221; &#8220;will,&#8221; &#8220;would,&#8221; &#8220;could,&#8221; &#8220;estimate,&#8221; &#8220;continue,&#8221; &#8220;anticipate,&#8221; &#8220;intend,&#8221; &#8220;project,&#8221; &#8220;endeavor,&#8221; &#8220;expect,&#8221; &#8220;plans to,&#8221; &#8220;if,&#8221; &#8220;future,&#8221; &#8220;likely,&#8221; &#8220;potentially,&#8221; and similar expressions are intended to identify forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about future events and trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives, and financial needs. These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including those described in Part I, Item&#160;1A, &#8220;Risk Factors&#8221; in this Annual Report on Form 10-K. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time, such as the COVID-19 global pandemic. Many of the risks and uncertainties are currently elevated by, and may or will continue to be elevated by, the current COVID-19 pandemic. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make.

Most of the print textbook transactions are rentals, although we also offer both new and used textbooks for sale at a slight markup to our acquisition cost. In 2014, we implemented a partnership with Ingram, which we expanded in May 2015, so that Ingram fulfilled our print textbook rentals and sales. In October 2019, we signed a strategic logistics agreement with FedEx Supply Chain, Inc. (FedEx). In January 2020, we began making purchases in our print textbook library and in February 2020, we began to transition logistics and warehousing services from Ingram to FedEx. We have also entered into agreements with other partners to provide their textbooks for rental or sale. In participation with certain publishers, we also offer &#8220;Instant Access&#8221; to eTextbooks as a one-week free trial of our eTextbook service, and allow the student to access the eTextbook while the print copy is in transit. All eTextbooks obtained from Chegg are viewed through our eTextbook reader which provides students with eTextbooks on PCs, tablets and smart phones, providing access anytime, anywhere that students are connected to the Internet and students can save a portion of the book for offline access. The eTextbook reader enables fast and easy navigation, keyword search, text highlighting, note taking and further preserves those notes in an online notepad with the ability to view highlighting and notes across platforms.</span></div><div style="text-indent:27pt"><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Technology and Platform Integration </span></div><div style="text-indent:27pt"><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Our technology is designed to create a direct-to-student learning platform that will continue to enable our growth at scale.

For Chegg Writing, we primarily face competition from other citation generating and grammar and plagiarism services such as Grammarly. For Chegg Math Solver and Mathway, we face competition from other equation solver services such as Photomath and Symbolab. For Thinkful, we face competition from other online learning platforms and online &#8220;skills accelerator&#8221; courses both in the direct-to-consumer category, including General Assembly, Galvanize, Inc., Flatiron School, Codecademy, DataCamp, and Lambda, Inc., as well as white-label and co-branded providers who compete for adult learners through third party institutions, including 2U, Inc., Simplilearn, and Kenzie Academy. Additionally, the market for textbooks is intensely competitive and subject to rapid change. We face competition from college bookstores, some of which are operated by Follett and Barnes&#160;&amp; Noble Education, online marketplaces such as Amazon.com, providers of eTextbooks, as well as various private textbook rental websites. Many students purchase from multiple textbook providers, are highly price sensitive, and can easily shift spending from one provider or format to another. As a consequence, our Required Materials product line, which includes eTextbooks, competes primarily on price and further on selection and functionality and compatibility of the eTextbook Reader we utilize across a wide variety of desktop and mobile devices.</span></div><div><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We believe that we have competitive strengths, some of which are discussed above, that position us favorably in each aspect of our business.

For example, we often cannot be certain how existing laws will apply in the e-commerce and online context, including with respect to such topics as privacy, defamation, pricing, credit card fraud, advertising, taxation, sweepstakes, promotions, content regulation, financial aid, scholarships, student matriculation and recruitment, quality of products and services, and intellectual property ownership and infringement.

The TCPA limits the use of automatic dialing systems, artificial or prerecorded voice messages, SMS text messages, and fax machines. It also applies to unsolicited text messages advertising the commercial availability of goods or services. Additionally, a number of states have enacted statutes that address telemarketing. For example, some states, such as California, Illinois, and New York, have created do-not-call lists. Other states, such as Oregon and Washington, have enacted &#8220;no rebuttal statutes&#8221; that require the telemarketer to end the call when the consumer indicates that he or she is not interested in the product being sold. Restrictions on telephone marketing, including calls and text messages, are enforced by the FTC, the Federal Communications Commission, states, and through the availability of statutory damages and class action lawsuits for violations of the TCPA. </span></div><div style="padding-left:60.75pt;text-indent:-15.75pt"><span><br/></span></div><div style="padding-left:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:1pt;font-weight:400;line-height:120%">&#160;</span></div><div style="padding-left:60.75pt;text-indent:-15.75pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#160;&#160;&#160;&#160;The Credit Card Accountability Responsibility and Disclosure Act of 2009, or CARD Act, and similar laws and regulations adopted by a number of states regulate credit card and gift certificate use fairness, including expiration dates and fees.

Should the COVID-19 pandemic continue, colleges may face reduced enrollment and reduced income. Further, if the COVID-19 pandemic continues to limit the functionality of colleges and universities, they may not have the financial resources to withstand prolonged declines in enrollment, diminishing revenues and even potential shutdowns and may be forced to close. Additionally, uncertainties surrounding the COVID-19 pandemic have forced colleges to pay heightened attention to alternative methods of instruction, including online learning and related concerns, such as proctoring exams. This increase in attention and demand may lead to additional scrutiny from the faculty of more traditional institutions, such as colleges or universities.</span></div><div><span><br/></span></div><div style="height:42.75pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">11</span></div></div></div><hr style="page-break-after:always"/><div style="min-height:42.75pt;width:100%"><div><span style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline"><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">T</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">a</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">b</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">l</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">e</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7"> </a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">o</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">f</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7"> </a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">C</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">o</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">n</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">t</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">e</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">n</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">t</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">s</a></span></div></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Our limited operating history and evolving offerings make it difficult to evaluate our current business and future prospects, and predict results of operations. </span></div><div><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Since July 2010, we have focused on expanding our offerings beyond textbooks, in many instances through the acquisition of other companies, such as Mathway and Thinkful.

Developing an enduring business model to serve this population is particularly challenging. Attracting new students depends not only on investment in our brand and our marketing efforts, but also on the perceived value of our products and services versus alternatives. If our efforts to satisfy our existing student user base are not successful or become less effective, or if the cost of such efforts were to significantly increase, we may not be able to attract new students as successfully or efficiently and, as a result, our business, results of operations, and financial condition could be adversely affected. </span></div><div><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Additionally, even if we succeed in establishing brand awareness and loyalty, we may be unable to maintain and grow our student user base if we cannot offer competitive prices for our products and services or adequately prevent unauthorized account sharing of our subscription program services.

If search engine companies modify their search algorithms in ways that are detrimental to our search result page ranking or in ways that make it harder for students to find our website, or if our competitors&#8217; SEO efforts are more successful than ours, overall growth could slow, including the number of subscribers to Chegg Services, student engagement could decrease, and fewer students may use our platform.

Our net losses for the years ended December 31, 2020, 2019, and 2018 were $6.2 million, $9.6 million, and $14.9 million, respectively. As of December&#160;31, 2020, we had an accumulated deficit of $422.6 million.

We may not succeed in increasing our revenues sufficiently to offset these higher expenses, and our efforts to grow the business may be more expensive than we anticipate.

To achieve profitability, we may need to change our operating infrastructure, scale our operations more efficiently, reduce our costs, or implement changes in our product and services offerings. If we fail to timely implement these changes or we cannot implement them for any reason, including due to factors beyond our control, our business may suffer.

If textbooks are not delivered timely to students, they could become dissatisfied and discontinue their use of our service, which could adversely affect our results of operations.</span></div><div><span><br/></span></div><div style="height:42.75pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">15</span></div></div></div><hr style="page-break-after:always"/><div style="min-height:42.75pt;width:100%"><div><span style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline"><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">T</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">a</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">b</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">l</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">e</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7"> </a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">o</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">f</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7"> </a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">C</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">o</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">n</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">t</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">e</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">n</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">t</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">s</a></span></div></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Revenues from Chegg Services, print textbooks that we own, and eTextbooks are primarily recognized ratably over the term a student subscribes to our Chegg Services, rents a print textbook or has access to an eTextbook. This has generally resulted in our highest revenues and profitability in the fourth quarter as it reflects more days of the academic year.  As a result of this seasonality, which corresponds to the academic calendar, our revenues may fluctuate significantly quarter to quarter depending upon the timing of where we are in our &#8220;rush&#8221; cycle and sequential quarter-over-quarter comparisons of our net revenues and operating results are not likely to be meaningful.

Brands may not do business with us, or may reduce their advertising spend with us, if we do not deliver ads, sponsorships, and other commercial content and marketing programs effectively, or if they do not believe that their investment will generate a competitive return relative to other alternatives. Additionally, if platforms such as Google Chrome, Safari, or Firefox, limit our access to or understanding of advertising and marketing audiences, they could reduce our advertising rates and ultimately reduce our revenues from brand advertising. For example, the release of iOS 14 on Apple devices brought with it a number of new changes, including the need for app users to opt in before their identifier for advertisers (&#8220;IDFA&#8221;) can be accessed by an app (which is currently expected to come into effect in 2021). Apple&#8217;s IDFA is a string of numbers and letters assigned to Apple devices which advertisers use to identify app users to deliver personalized and targeted advertising. As more users opt out of granting IDFA access, the ability of advertisers to accurately target and measure their advertising campaigns at the user level may become significantly limited and we may experience increased cost per registration. Our ability to grow the number of brands that use our brand advertising, and ultimately to generate advertising revenues, depends on a number of factors, some of which are outside of our control, such as the impact of macroeconomic conditions and legal developments relating to data privacy, advertising, legislation and regulation and litigation. </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Our core value of putting students first may conflict with the short-term interests of our business.</span></div><div><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We believe that adhering to our core value of putting students first is essential to our success and in the best interests of our company and the long-term interests of our stockholders.

The COVID-19 pandemic has adversely affected federal and state budgets for education and caused significant economic volatility. To the extent that these trends continue or the economy stagnates or worsens, students may elect to not attend colleges and universities and reduce the amount they spend on educational content and textbooks.

The taxing authorities of the jurisdictions in which we operate may challenge our methodologies for valuing and allocating income from our intercompany transactions, which could increase our worldwide effective income tax rate.  We collect sales taxes in all U.S. states with a sales tax and most local jurisdictions on our sales, rentals, and digital services sold through our commerce system including sales and rentals on behalf of our third-party publishers.  In June 2018, the U.S. Supreme Court in South Dakota v. Wayfair, Inc. et al ruled that a state can require an online retailer with no in-state property or personnel to collect and remit sales and use tax on sales made to the state&#8217;s residents. It is possible that such taxes could be assessed by certain states retroactively for periods before the Wayfair decision on acquired products that are not sold through our commerce system.

An immaterial portion of the state net operating loss carryforwards expired in 2020. At December&#160;31, 2020, we also had federal tax credit carryforwards of approximately $19.1 million, which if not utilized will begin to expire in 2030, and state tax credit carryforwards of approximately $14.8 million, which do not expire. These net operating loss and tax credit carryforwards could expire unused and be unavailable to offset future income tax liabilities, which could adversely affect our profitability. For example, we have net operating loss carryforwards of $26&#160;million related to our previous operations in Kentucky that will expire unused unless we have similar operations in Kentucky. Additionally, in response to the COVID-19 pandemic, California&#8217;s Legislature passed Assembly Bill 85 (A.B. 85), which suspends the use of net operating losses for tax years beginning in 2020, 2021, and 2022 for taxpayers with taxable income of $1.0 million or more before an application of net operating loss. A.B. 85 includes an extended carryover period for the suspended net operating losses with an additional year carryforward for each year of suspension. A.B. 85 also limits the utilization of business incentive tax credits for taxable years 2020, 2021, and 2022, requiring that taxpayers can only claim a maximum of $5.0 million in tax credit on an aggregate basis. </span></div><div><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The 2017 Tax Act changed both the federal deferred tax value of the net operating loss carryforwards and the rules of utilization of federal net operating loss carryforwards. The 2017 Tax Act lowered the corporate tax rate from 35% to 21% effective for our 2018 financial year. For net operating loss carryforwards generated in years prior to 2018, there is no annual limitation on the utilization and the carryforward period remains at 20 years; net operating loss carryforwards generated in years after 2017 will only be available to offset 80% of future taxable income in any single year but will not expire. However, the Coronavirus Aid, Relief, and Economic Security (CARES) Act temporarily repealed the 80% taxable income limitation for tax years beginning before January 1, 2021; net operating loss carried forward from 2018 or later to taxable years beginning after December 31, 2020 will be subject to the 80% limitation. Also, under the CARES Act, net operating loss arising in 2018, 2019 and 2020 can be carried back five years.</span></div><div><span><br/></span></div><div style="height:42.75pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">19</span></div></div></div><hr style="page-break-after:always"/><div style="min-height:42.75pt;width:100%"><div><span style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline"><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">T</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">a</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">b</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">l</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">e</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7"> </a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">o</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">f</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7"> </a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">C</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">o</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">n</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">t</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">e</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">n</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">t</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">s</a></span></div></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In addition, under Section 382 of the Internal Revenue Code of 1986, as amended (the Code), our ability to utilize net operating loss carryforwards or other tax attributes, such as tax credits, in any taxable year may be limited if we experience an &#8220;ownership change.&#8221; A Section 382 &#8220;ownership change&#8221; generally occurs if one or more stockholders or groups of stockholders who own at least 5% of our stock increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. Similar rules may apply under state tax laws.

Although today our international operations represent less than 10% of our total consolidated operating expenses, we expect to continue to expand our international operations, and to make our products and services available in more international markets. However, we have a limited operating history in international jurisdictions and expanding our international operations will require considerable management attention and resources to attract talented employees and users.  International operations are subject to particular challenges and risks, some of which we may not currently face, including multiple languages, cultures, customs, tax systems, legal systems, alternative dispute systems, regulatory systems, and commercial infrastructures. Further, such operations may exacerbate existing risks, including risks associated with employees, compliance with applicable foreign laws and regulations, protecting and enforcing intellectual property rights, and complying with anti-bribery laws. New international markets may also have educational systems, technology, and online industries that are different, more regulated, or less well developed than those in the United States, and if we cannot address these challenges, it could have an adverse effect on our business, results of operations, and financial conditions.

These estimates and assumptions involve matters that are inherently uncertain and require us to make subjective and complex judgments. Although we believe we have the experience and processes to enable us to formulate appropriate assumptions and produce reasonably dependable estimates, these assumptions and estimates may change significantly in the future and could result in the reversal of previously recognized revenues and profit.

We also may face liability for content uploaded by students in connection with our community-related content. If we become liable, third parties may initiate litigation against us and our business may suffer. For example, in June 2017, the Examinations Institute of the American Chemical Society filed a complaint against us in the U.S. District Court for the Northern District of California claiming, among other things, that we infringed their copyrights by answering and displaying questions uploaded by our users to our Q&amp;A service. Others may send us communications that make allegations without initiating litigation. We have in the past and may in the future receive such communications, which we assess on a case-by-case basis. We may elect not to respond to the communication if we believe it is without merit or we may try to resolve disputes out-of-court by removing content or services we offer or paying licensing or other fees. If we cannot resolve such disputes, litigation may result. Litigation to defend these claims could be costly, divert our technical and management personnel, render us unable to use our current website or to market our service or sell our products and therefore harm our results of operations. We may not be adequately insured to cover claims of these types or indemnified for all liability that may be imposed on us.

We have in the past received and expect to continue to receive, communications alleging that physical textbooks sold or rented by us are counterfeit. While our fulfillment partner has systems for inspecting the physical textbooks in our catalog of textbooks, many of the textbooks sold or rented to students are shipped directly from our suppliers, and, despite inspection, unauthorized or counterfeit textbooks may inadvertently be included in the catalog of textbooks we offer and may be, without our knowledge that they are unauthorized or counterfeit, subsequently sold or rented by us to students, and we may be subject to allegations of civil or criminal liability. We may implement additional measures in an effort to protect against these potential liabilities that could require us to spend substantial resources.

To date, no social security numbers or financial information such as users&#8217; credit card numbers or bank account information were obtained. Additionally, Thinkful, prior to our acquisition of it, discovered an unauthorized party may have gained access to certain Thinkful company credentials (the Thinkful Data Incident). If we, or companies that we acquire, experience security compromises that result in website performance or availability problems, the complete shutdown of our websites, or the actual or perceived loss or unauthorized disclosure or use of confidential information, such as credit card information, users may be harmed or lose trust and confidence in us, and decrease the use of our services or stop using our services in their entirety, and we would suffer reputational and financial harm, in addition to increased regulatory scrutiny, litigation, fines, and governmental enforcement actions.</span></div><div><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">As part of our regular cybersecurity efforts, including enhancements to our cybersecurity controls made following our discovery of these prior events, we have implemented physical, technical, and administrative safeguards designed to protect our systems.

Additionally, our network security business disruption insurance may not be sufficient to cover significant expenses and losses related to direct attacks on our website or systems we use. Any failure to maintain performance, reliability, security, and availability of our products and services and technical infrastructure, or the actual or perceived loss or unauthorized disclosure or use of the data we collect and develop may lead our users to lose trust and confidence in us or otherwise harm our reputation, brand, and our ability to attract students to our website or may lead them to decrease the use of our services or applications or stop using our services in their entirety.

Such breach notification laws continue to evolve and may be inconsistent from one jurisdiction to another.

Such interruptions could have a disproportionate effect on our operations if they were to occur during one of our peak periods or if multiple of our service facilities experiences outages at the same time.

Any changes in such laws and regulations or a change or differing interpretation or application to our business of the existing laws and regulations, including the GDPR, could also hinder our operational flexibility, raise compliance costs and, particularly if our compliance efforts are deemed to be insufficient, result in additional historical or future liabilities and regulatory scrutiny for us, resulting in adverse impacts on our business and our results of operations.</span></div><div style="height:42.75pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">25</span></div></div></div><hr style="page-break-after:always"/><div style="min-height:42.75pt;width:100%"><div><span style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline"><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">T</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">a</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">b</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">l</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">e</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7"> </a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">o</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">f</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7"> </a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">C</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">o</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">n</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">t</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">e</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">n</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">t</a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:7pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i946835227a374490bd6da6a919c4fbf8_7">s</a></span></div></div><div><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In addition, we may be subject to regulatory investigations or litigation in connection with a security breach or related issue, and we could also be liable to third parties for these types of breaches.

The complaint was filed by a purported Chegg stockholder and alleges claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, based on allegedly misleading statements regarding our security measures to protect users&#8217; data and related internal controls and procedures, as well as our second quarter 2018 financial results. Such litigation, regulatory investigations, and our technical activities intended to prevent future security breaches are likely to require additional management resources and expenditures. </span></div><div><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Additionally, the CCPA provides for a private right of action for security breaches that is expected to increase security breach litigation that could lead to some form of remedy including regulatory scrutiny, fines, private right of action settlements, and other consequences. If our security measures fail to protect personal information and data supplied by students and tutors adequately, we could be liable to our students and tutors for their losses, we could face regulatory action, and our students and tutors could end their relationships with us, any of which could harm our business and financial results. Further, on June 18, 2020, we received a CID from the FTC to determine whether we may have violated Section 5 of the FTC Act or the COPPA, as they relate to deceptive or unfair acts or practices related to consumer privacy and/or data security. Also, as of October 2020, we have received notices that an aggregate of 16,691 arbitration demands were filed against us by individuals alleging to have suffered damages in connection with the 2018 Data Incident. For further information on such actions, see Note 12, &#8220;Commitments and Contingencies,&#8221; of our accompanying Notes to Consolidated Financial Statements included in Part II, Item 8, &#8220;Consolidated Financial Statements and Supplementary Data&#8221; of this Annual Report on Form 10-K. </span></div><div><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Any failure or perceived failure by us to comply with our privacy policies, our privacy or data-protection obligations to students or other third parties, our privacy or data-protection legal obligations, or any compromise of security that results in the unauthorized release or transfer of sensitive information, which may include personal information or other data, may result in governmental enforcement actions, litigation, or public statements against us by consumer advocacy groups or others and could cause students to lose trust in us, which could have an adverse effect on our business.

Practices regarding the collection, use, storage, display, processing, transmission and security of personal information by companies offering online services have recently come under increased public scrutiny. The U.S. government, including the White House, the FTC and the U.S. Department of Commerce, have reviewed the need for greater regulation of the collection and use of information concerning consumer behavior with respect to online services, including regulation aimed at restricting certain targeted advertising practices. The FTC in particular has approved consent decrees resolving complaints and their resulting investigations into the privacy and security practices of a number of online, and social media companies. On June 18, 2020, we received a CID from the FTC to determine whether we may have violated Section 5 of the FTC Act or the COPPA, as they relate to deceptive or unfair acts or practices related to consumer privacy and/or data security, as further described in Note 12, &#8220;Commitments and Contingencies,&#8221; of our accompanying Notes to Consolidated Financial Statements included in Part II, Item 8, &#8220;Consolidated Financial Statements and Supplementary Data&#8221; of this Annual Report on Form 10-K. Similar actions may also impact us directly, particularly because of the current subject of the CID and because high school students who use our Chegg Writing and Chegg Prep services, may be under the age of 18, which subjects our business to laws covering the protection of minors. For example, various U.S. and international laws restrict the distribution of materials considered harmful to children and impose additional restrictions on the ability of online services to collect information from minors. Although our services are not primarily directed to children under 13, our Chegg Writing service or our Chegg Prep service, in particular, could be used by students as early as in middle school, and the FTC could decide that our site now or in the future has taken inadequate precautions to prevent children under 13 from accessing our site and providing us information.</span></div><div><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Our business, including our ability to operate internationally, could be adversely affected if legislation or regulations are adopted, interpreted or implemented in a manner that is inconsistent with our current business practices and that require changes to these practices, the design of our websites, mobile applications, products, features or our privacy policy.

have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of companies in general and technology companies in particular. These fluctuations often have been unrelated or disproportionate to the operating performance of those companies. Technology companies have been particularly susceptible to stock price volatility. In the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We have been and may continue to be the target of this type of litigation in the future.

A short seller hopes to profit from a decline in the value of the securities between the sale of the borrowed securities and the purchase of the replacement shares. Because it is in the short seller&#8217;s best interests for the price of the stock to decline, some short sellers publish, or arrange for the publication of, opinions or characterizations regarding the relevant issuer, its business prospects, and similar matters calculated to or which may create negative market momentum. Short sellers can publicly attack a company&#8217;s reputation and business on a broader scale via online postings. In the past, the publication of such commentary about us by a disclosed short seller has precipitated a decline in the market price of our common stock, and future similar efforts by other short sellers may have similar effects.</span></div><div style="text-indent:27pt"><span><br/></span></div><div style="height:42.75pt;position:relative;width:100%"><div

If we elect to deliver shares of our common stock to settle such conversion, the issuance of our common stock may cause immediate and significant dilution.  </span></div><div><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In addition, our ability to repurchase the notes or to pay cash upon conversions of notes may be limited by law, regulatory authority or agreements governing any future indebtedness. Our failure to repurchase the notes at a time when the repurchase is required by the indenture or to pay cash upon conversions of notes as required by the indenture would constitute a default under the indenture. A default under the indenture or the fundamental change itself could also lead to a default under agreements governing any future indebtedness. If the payment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the notes or to pay cash upon conversions of notes.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">General Risk Factor</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Our operations are susceptible to earthquakes, floods, rolling blackouts and other types of power loss, and public health crises, including the current COVID-19 pandemic.

December&#160;31, 2020, compared to the same period in 2019, primarily due to a 67% increase in subscriber growth driven by increased global penetration, our efforts to reduce account sharing, the widespread transition to remote learning as a result of the COVID-19 pandemic, and subscribers from our recent acquisitions. We currently expect to continue to see growth in Chegg Services revenues in the near term as a result of the aforementioned drivers in subscriber growth, most significantly from the contribution of international subscribers, however, we expect such drivers to become less pronounced.  Chegg Services revenues represented 81% of net revenues during each of the years ended December 31, 2020 and 2019.  Required Materials revenues increased by $44.4 million, or 56%, during the year ended December&#160;31, 2020 compared to the same period in 2019, primarily due to revenues from print textbooks that we own which are recognized as the total transaction amount ratably over the lease term as opposed to a revenue share on the total transaction amount of a rental or sale transaction immediately when a print textbook ships to a student. Required Materials revenues represented 19% of net revenues during each of the years ended December&#160;31, 2020 and 2019. We currently expect the contribution of Required Materials revenues as a percentage of net revenues to decline in the near term as Chegg Services revenues continue to grow.</span></div><div style="text-indent:27pt"><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Chegg Services revenues increased by $78.2 million, or 31%, during the year ended December&#160;31, 2019, compared to the same period in 2018 primarily due to a 29% increase in subscriber growth as more students turned to our services and we expanded the subject matter content that drives our offerings. Chegg Services revenues represented 81% and 79% of net revenues during the years ended December&#160;31, 2019 and 2018, respectively. Required Materials revenues increased by $11.6 million, or 17%, during the year ended December&#160;31, 2019 compared to the same period in 2018, primarily due to better performance from our Required Materials print textbook partners as well as recognition of deferred variable consideration. Required Materials revenues represented 19% and 21% of net revenues during the years ended December&#160;31, 2019 and 2018, respectively.</span></div><div

In determining this estimate, we consider the single most likely amount in a range of possible amounts. This estimated amount of variable consideration requires management to make a judgment based on the forecasted amount of consideration that we expect we will earn as well as the time period in which we can reasonably rely on the accuracy of the forecast. Our estimate of variable consideration is constrained to only include the amount of variable consideration for which it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur, as the amounts that we could potentially earn in outer years can change significantly based on factors that are out of our control.

Significant estimates, assumptions, and judgments are used for, but not limited to: revenue recognition, recoverability of accounts receivable, share-based compensation expense including estimated forfeitures, accounting for income taxes, useful lives and salvage value assigned to our textbook library, useful lives assigned to long-lived assets for depreciation and amortization, impairment of goodwill and long-lived assets, the valuation of acquired intangible assets, the valuation of our convertible senior notes, internal-use software and website development costs, operating lease right of use (ROU) assets, and operating lease liabilities. We base our estimates on historical experience, knowledge of current business conditions, and various other factors we believe to be reasonable under the circumstances. These estimates are based on management&#8217;s knowledge about current events and expectations about actions we may undertake in the future. Actual results could differ from these estimates, and such differences could be material to our financial position and results of operations.</span></div></ix:nonNumeric><div style="text-indent:27pt"><span><br/></span></div><ix:nonNumeric contextRef="i275fa4de69484fcc8393b17e2d8bddbd_D20200101-20201231" name="us-gaap:ConsolidationPolicyTextBlock" id="id3VybDovL2RvY3MudjEvZG9jOjk0NjgzNTIyN2EzNzQ0OTBiZDZkYTZhOTE5YzRmYmY4L3NlYzo5NDY4MzUyMjdhMzc0NDkwYmQ2ZGE2YTkxOWM0ZmJmOF8xMTgvZnJhZzoyYjY5MjU5MGRiNGY0MzJlODZiNTZkYzIyZGI1M2EwMS90ZXh0cmVnaW9uOjJiNjkyNTkwZGI0ZjQzMmU4NmI1NmRjMjJkYjUzYTAxXzMwODQ1_6366551b-7cae-4683-8789-7ab34105f978" escape="true"><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Principles of Consolidation</span></div><div><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The consolidated financial statements include the accounts of Chegg and our wholly owned subsidiaries.

Where leases contain escalation clauses, rent abatements, or concessions, such as rent holidays and landlord or tenant incentives or allowances, we apply them in the determination of straight-line operating lease cost over the lease term.</ix:continuation></span></div><div style="text-indent:27pt"><span><br/></span></div><ix:nonNumeric contextRef="i275fa4de69484fcc8393b17e2d8bddbd_D20200101-20201231" name="chgg:StrategicInvestmentPolicyTextBlock" id="id3VybDovL2RvY3MudjEvZG9jOjk0NjgzNTIyN2EzNzQ0OTBiZDZkYTZhOTE5YzRmYmY4L3NlYzo5NDY4MzUyMjdhMzc0NDkwYmQ2ZGE2YTkxOWM0ZmJmOF8xMTgvZnJhZzoyYjY5MjU5MGRiNGY0MzJlODZiNTZkYzIyZGI1M2EwMS90ZXh0cmVnaW9uOjJiNjkyNTkwZGI0ZjQzMmU4NmI1NmRjMjJkYjUzYTAxXzMwOTE4_3baadff4-ac77-4880-af6a-d538f7120bdf" escape="true"><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Strategic Investments</span></div><div><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We have entered into strategic investments that do not have readily determinable fair values and have elected to account for these investments at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer, if any.

Collectively, the 2026 notes, 2025 notes and the 2023 notes are referred to as the &#8220;notes.&#8221; In accounting for their issuance, we separated the notes into liability and equity components, as the notes represent convertible instruments with a cash conversion feature. The carrying amount of the liability component was calculated by measuring the fair value of similar liabilities that do not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the carrying amount of the liability component from the par value of the notes. The difference represents the debt discount, recorded as a reduction of the convertible senior notes on our consolidated balance sheet, and is amortized to interest expense over the term of the notes using the effective interest rate method. The carrying amount of the liability component is classified as a long-term liability as we have the election to settle conversion requests in shares of our common stock. The carrying amount of the equity component is not remeasured as long as it continues to meet the conditions for equity classification. In accounting for the issuance costs related to the notes, we allocated the total amount of issuance costs incurred to liability and equity components based on their relative values. Issuance costs attributable to the liability component are being amortized on a straight-line basis, which approximates the effective interest rate method, to interest expense over the term of the notes. The issuance costs attributable to the equity component are recorded as a reduction of the equity component within additional paid-in capital. In accounting for extinguishment of the notes, we allocated the consideration transferred between the liability and equity components in a similar manner as upon issuance. The liability component for extinguished notes is then compared to the carrying amount of the respective extinguished notes and a gain or loss is recorded in other income, net on our consolidated statements of operations.</span></div></ix:nonNumeric><div style="text-indent:27pt"><span><br/></span></div><ix:nonNumeric contextRef="i275fa4de69484fcc8393b17e2d8bddbd_D20200101-20201231" name="chgg:TextbookLibraryPolicyTextBlock" id="id3VybDovL2RvY3MudjEvZG9jOjk0NjgzNTIyN2EzNzQ0OTBiZDZkYTZhOTE5YzRmYmY4L3NlYzo5NDY4MzUyMjdhMzc0NDkwYmQ2ZGE2YTkxOWM0ZmJmOF8xMTgvZnJhZzoyYjY5MjU5MGRiNGY0MzJlODZiNTZkYzIyZGI1M2EwMS90ZXh0cmVnaW9uOjJiNjkyNTkwZGI0ZjQzMmU4NmI1NmRjMjJkYjUzYTAxXzM4NDgyOTA3NTQyMTc_4c3cf971-0c61-4e3a-8cec-3ad0920baeb9" continuedAt="i25586348abe044d5a5198d36b14062e3" escape="true"><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Textbook Library</span></div><div><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Beginning in January 2020, we began our transition back to print textbook ownership by purchasing print textbooks to establish our textbook library.

For these arrangements that contain multiple performance obligations, we allocate the transaction price based on the relative standalone selling price (SSP) method by comparing the SSP of each distinct performance obligation to the total value of the contract. We determine the SSP based on our historical pricing and discounting practices for the distinct performance obligation when sold separately.  If the SSP is not directly observable, we estimate the SSP by considering information such as market conditions, and information about the customer.

Valuation allowances are established, when necessary, to reduce deferred tax assets to an amount that is more likely than not to be realized. We record uncertain tax positions on the basis of a two-step process in which (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of technical merits of the position and (2) for those tax positions that meet the more likely than not recognition threshold, we recognize the tax benefit as the largest amount that is cumulative more than 50% likely to be realized upon ultimate settlement with the related tax authority.

On January 1, 2020, we adopted ASC 326, which replaces the existing incurred loss impairment model for financial assets, including trade receivables, with an expected loss model which requires the use of forward-looking information to calculate expected credit loss estimates. Additionally, the concept of other-than-temporary impairment for available-for-sale investments is eliminated and instead requires us to focus on determining whether any unrealized loss is a result of a credit loss or other factors.

prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. Other than our money market funds and U.S. treasury securities, we classify our fixed income available-for-sale investments as having Level 2 inputs. The valuation techniques used to measure the fair value of our investments having Level 2 inputs were derived from non-binding market consensus prices that are corroborated by observable market data, quoted market prices for similar instruments, or pricing models such as discounted cash flow techniques.

Our management assessed the effectiveness of our internal control over financial reporting as of December&#160;31, 2020. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control&#8212;Integrated Framework (2013 framework). The Company has excluded the financial results of Mathway from its evaluation of its internal control over financial reporting, which financial results are included in the&#160;December&#160;31, 2020&#160;consolidated financial statements and constituted less than 1% of total assets as of December&#160;31, 2020, and approximately 2% of total net revenues during the year ended December&#160;31, 2020. All control systems are subject to inherent limitations. Our management has concluded that, as of December&#160;31, 2020, our internal control over financial reporting is effective based on these criteria. Additionally, our independent registered public accounting firm, Deloitte &amp; Touche LLP, has issued an audit report on the Company's internal control over financial reporting, which appears in Part II, Item 8 of this Annual Report on Form 10-K.</span></div><div style="text-indent:27pt"><span><br/></span></div><div style="padding-left:18pt;text-indent:-18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">(c)</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%;padding-left:6.91pt">Changes in Internal Control over Financial Reporting</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">During the quarter ended December 31, 2020, there were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rules 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during our most recently completed fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. </span><span style="color:#212529;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We continue to monitor the impact of the COVID-19 pandemic and, despite many of our employees working remotely, have not experienced any changes that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.</span></div><div style="text-align:justify;text-indent:27pt"><span><br/></span></div><div id="i946835227a374490bd6da6a919c4fbf8_205"></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">ITEM&#160;9B.

Significant estimates, assumptions, and judgments are used for, but not limited to: revenue recognition, recoverability of accounts receivable, share-based compensation expense including estimated forfeitures, accounting for income taxes, useful lives and salvage value assigned to our textbook library, useful lives assigned to long-lived assets for depreciation and amortization, impairment of goodwill and long-lived assets, the valuation of acquired intangible assets, the valuation of our convertible senior notes, internal-use software and website development costs, operating lease right of use (ROU) assets, and operating lease liabilities. We base our estimates on historical experience, knowledge of current business conditions, and various other factors we believe to be reasonable under the circumstances. These estimates are based on management&#x2019;s knowledge about current events and expectations about actions we may undertake in the future. Actual results could differ from these estimates, and such differences could be material to our financial position and results of operations.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Principles of Consolidation&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The consolidated financial statements include the accounts of Chegg and our wholly owned subsidiaries.

Our cash and cash equivalents consist of cash and money market accounts at financial institutions, and are stated at cost, which approximates fair value. We classify certain restricted cash balances within other current assets and other assets on the accompanying consolidated balance sheets based upon the term of the remaining restrictions. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Investments&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We hold investments in commercial paper, corporate debt securities, and agency bonds. We classify our investments as available-for-sale that are either short or long-term based on the nature of each security based on the remaining contractual maturity of the investment. Our available-for-sale investments are carried at estimated fair value with any unrealized gains and losses, unrelated to credit loss factors, net of taxes, included in other comprehensive income (loss) on our consolidated statements of stockholders&#x2019; equity. Beginning in 2020, unrealized losses related to credit loss factors are now recorded through an allowance for credit losses in other income, net on our consolidated statements of operations, rather than as a reduction to the amortized costs basis in other comprehensive income (loss), when a decline in fair value has resulted from a credit loss. We determine realized gains or losses on the sale of investments on a specific identification method, and record such gains or losses as other income, net. For the years ended&#160;December&#160;31, 2020, 2019 and 2018, the Company's gross realized gains and losses on investments were not significant.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Accounts Receivable, Net of Allowance&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Accounts receivable are recorded at the invoiced amount and are non-interest bearing. We generally grant uncollateralized credit terms to our customers, which include textbook wholesalers and advertising customers. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We maintain an allowance to account for potentially uncollectible receivables. We assess the creditworthiness of our customers based on multiple sources of information, and analyze such factors as our historical bad debt experience, industry and geographic concentrations of credit risk, economic trends, and customer payment history. This assessment requires significant judgment. Because of this assessment, we maintain an allowance for estimated losses resulting from the inability of certain customers to make all of their required payments. In making this estimate, we analyze historical payment performance and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. Accounts receivable are written off as a decrease to the allowance when all collection efforts have been exhausted and an account is deemed uncollectible.&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;&#160;&#160;&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Concentration of Credit Risk&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, and investments in highly liquid instruments in accordance with our investment policy. We place the majority of our cash and cash equivalents and restricted cash with financial institutions in the United States that we believe to be of high credit quality, and accordingly minimal credit risk exists with respect to these instruments. Certain of our cash balances held with a financial institution are in excess of Federal Deposit Insurance Corporation limits. Our investment portfolio consists of investments diversified among security types, industries and issuers. Our investments were held and managed by recognized financial institutions that followed our investment policy with the main objective of preserving capital and maintaining liquidity.&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Concentrations of credit risk with respect to accounts receivables exist to the full extent of amounts presented in the financial statements. We had one customer, in each year, that represented 10% and 11% of our net accounts receivable balance as of&#160;December&#160;31, 2020 and 2019, respectively. No customers represented over&#160;10%&#160;of net revenues during the years ended December&#160;31, 2020,&#160;2019&#160;or&#160;2018.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Property and Equipment&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Property and equipment are recorded at cost less accumulated depreciation and content amortization.

The excess of the fair value of purchase consideration over the fair values of these identifiable assets acquired and liabilities assumed is recorded as goodwill. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired users, acquired technology, and trade names from a market participant perspective, useful lives and discount rates. Management&#x2019;s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, which is not to exceed one year from the acquisition date, we may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Goodwill and Indefinite-Lived Intangible Asset&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Goodwill represents the excess of the fair value of purchase consideration paid over the estimated fair value of assets acquired and liabilities assumed in a business combination. Our indefinite-lived intangible asset represents the internships.com trade name. Goodwill and our indefinite-lived intangible asset are not amortized but rather tested for impairment at least annually on October 1, or more frequently if certain events or indicators of impairment occur between annual impairment tests. We first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. In our qualitative assessment, we consider factors including economic conditions, industry and market conditions and developments, overall financial performance and other relevant entity-specific events in determining whether it is more likely than not that the fair value of our reporting unit is less than the carrying amount. We completed our annual impairment test on October 1st of 2020 and 2019, each of which did not result in any impairment as our qualitative assessment did not indicate that it is more likely than not that the fair value of our reporting unit is less than the carrying amount.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Acquired Intangible Assets and Other Long-Lived Assets&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Acquired intangible assets with finite useful lives, which include developed technology, content library, customer lists, trade names, domain names, and non-compete agreements, are amortized over their estimated useful&#160;lives. We assess the impairment of acquired intangible assets and other long-lived assets when events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Leases&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We determine if an arrangement is a lease at inception. Operating leases are included in operating lease ROU assets and operating lease liabilities within current liabilities and long-term liabilities on our consolidated balance sheets. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. Our leases do not provide an implicit rate and therefore we use our incremental borrowing rate based on the information available at commencement date in determining the present value of future minimum lease payments. Our incremental borrowing rate is estimated based on the estimated rate incurred to borrow, on a collateralized basis over a similar term as our leases, an amount equal to the lease payments in a similar economic environment. Our lease &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise such options. We do not record leases on our consolidated balance sheet with a term of one year or less. We do not separate lease and non-lease components but rather account for each separate component as a single lease component for all underlying classes of assets. Some of our leases include payments that are dependent on an index, such as the Consumer Price Index (CPI), and our minimum lease payments include payments based on the index at inception with any future changes in such indices recognized as an expense in the period of change. Where leases contain escalation clauses, rent abatements, or concessions, such as rent holidays and landlord or tenant incentives or allowances, we apply them in the determination of straight-line operating lease cost over the lease term.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Strategic Investments&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We have entered into strategic investments that do not have readily determinable fair values and have elected to account for these investments at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer, if any. Strategic investments are included in other assets on our consolidated balance sheets. We assess our strategic investments for impairment whenever events or changes in circumstances indicate that they may be impaired. The factors we consider in our evaluation include, but are not limited to, a significant deterioration in the earnings performance or business prospects of the investee or factors that raise significant concerns about the investee&#x2019;s ability to continue as a going concern, such as negative cash flows from operations or working capital deficiencies.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Convertible Senior Notes, net&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In August 2020, we issued $1.0 billion in aggregate principal amount of 0% convertible senior notes due in 2026 (2026 notes). In March 2019, we issued $700 million in aggregate principal amount of&#160;0.125%&#160;convertible senior notes due in 2025 (2025 notes) and in April 2019, the initial purchasers fully exercised their option to purchase $100 million of additional 2025 notes for aggregate total gross proceeds of $800 million. In April 2018, we issued&#160;$345 million in aggregate principal amount of&#160;0.25%&#160;convertible senior notes due in 2023 (2023 notes). Collectively, the 2026 notes, 2025 notes and the 2023 notes are referred to as the &#x201c;notes.&#x201d; In accounting for their issuance, we separated the notes into liability and equity components, as the notes represent convertible instruments with a cash conversion feature. The carrying amount of the liability component was calculated by measuring the fair value of similar liabilities that do not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the carrying amount of the liability component from the par value of the notes. The difference represents the debt discount, recorded as a reduction of the convertible senior notes on our consolidated balance sheet, and is amortized to interest expense over the term of the notes using the effective interest rate method. The carrying amount of the liability component is classified as a long-term liability as we have the election to settle conversion requests in shares of our common stock. The carrying amount of the equity component is not remeasured as long as it continues to meet the conditions for equity classification. In accounting for the issuance costs related to the notes, we allocated the total amount of issuance costs incurred to liability and equity components based on their relative values. Issuance costs attributable to the liability component are being amortized on a straight-line basis, which approximates the effective interest rate method, to interest expense over the term of the notes. The issuance costs attributable to the equity component are recorded as a reduction of the equity component within additional paid-in capital. In accounting for extinguishment of the notes, we allocated the consideration transferred between the liability and equity components in a similar manner as upon issuance. The liability component for extinguished notes is then compared to the carrying amount of the respective extinguished notes and a gain or loss is recorded in other income, net on our consolidated statements of operations.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Textbook Library&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Beginning in January 2020, we began our transition back to print textbook ownership by purchasing print textbooks to establish our textbook library. We consider our print textbook library to be a long-term productive asset and, as such, classify it as a non-current asset on our consolidated balance sheets. All print textbooks in our textbook library are stated at cost, which includes the purchase price less accumulated depreciation. We write down textbooks on a book-by-book basis for lost, damaged, or excess print textbooks.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We depreciate our print textbooks, less an estimated salvage value, over an estimated useful life of four years using an accelerated method of depreciation, as we estimate this method most accurately reflects the actual pattern of decline in their economic value. The salvage value considers the historical trend and projected proceeds for print textbooks. The useful life is determined based on the estimated time period in which the print textbooks are held and rented. We review the estimated salvage value and useful life of our print textbook library on an ongoing&#160;basis. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Write-downs for print textbooks, print textbook depreciation expense, the gain or loss on print textbooks liquidated, and the net book value of print textbooks purchased by students at the end of the term or on a just-in-time basis are recorded in cost of revenues on our consolidated statements of operations and classified as adjustments to cash flows from operating activities. Cash outflows for the acquisition of print textbooks net of changes in related accounts payable and accrued liabilities, and cash inflows received from the proceeds from the disposition of print textbooks net of changes in related accounts receivable, are classified as cash flows from investing activities on our consolidated statements of cash flows.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Revenue Recognition and Deferred Revenue&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We recognize revenues when the control of goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services.

Operating lease income is recognized as the total transaction amount, paid upon commencement of the lease, ratably over the lease term or rental term, generally a &lt;span style="-sec-ix-hidden:id3VybDovL2RvY3MudjEvZG9jOjk0NjgzNTIyN2EzNzQ0OTBiZDZkYTZhOTE5YzRmYmY4L3NlYzo5NDY4MzUyMjdhMzc0NDkwYmQ2ZGE2YTkxOWM0ZmJmOF8xMTgvZnJhZzoyYjY5MjU5MGRiNGY0MzJlODZiNTZkYzIyZGI1M2EwMS90ZXh0cmVnaW9uOjJiNjkyNTkwZGI0ZjQzMmU4NmI1NmRjMjJkYjUzYTAxXzQzOTgwNDY1NzcwNDE_05aadfd2-1539-41f1-9bab-3425e7f2aecd"&gt;two&lt;/span&gt;- to five-month period. Students generally have the option to extend the term of their rental or purchase the print textbook at the end of the term otherwise the print textbook is returned to our print textbook library for future rental. If a student chooses to purchase or not return the print textbook at the end of their rental term, we charge the student for the book and recognize the revenues immediately. Additionally, we provide students the ability to purchase print textbooks on a just-in-time basis and recognize revenues immediately upon shipment.  Revenues from print textbooks owned by a partner are recognized as a revenue share on the total transaction amount of a rental or sale transaction immediately when a print textbook ships to a student. Shipping and handling activities are expensed as incurred. Revenues from eTextbooks are recognized ratably over the contractual period, generally a &lt;span style="-sec-ix-hidden:id3VybDovL2RvY3MudjEvZG9jOjk0NjgzNTIyN2EzNzQ0OTBiZDZkYTZhOTE5YzRmYmY4L3NlYzo5NDY4MzUyMjdhMzc0NDkwYmQ2ZGE2YTkxOWM0ZmJmOF8xMTgvZnJhZzoyYjY5MjU5MGRiNGY0MzJlODZiNTZkYzIyZGI1M2EwMS90ZXh0cmVnaW9uOjJiNjkyNTkwZGI0ZjQzMmU4NmI1NmRjMjJkYjUzYTAxXzQzOTgwNDY1Nzc0MTk_ec7d2d2c-c08e-4875-9cf4-4d6a502fe15a"&gt;two&lt;/span&gt;- to five-month period. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Some of our customer arrangements include multiple performance obligations. We have determined these performance obligations qualify as distinct performance obligations, as the customer can benefit from the service on its own or together with other resources that are readily available to the customer, and our promise to transfer the service is separately identifiable from other promises in the contract. For these arrangements that contain multiple performance obligations, we allocate the transaction price based on the relative standalone selling price (SSP) method by comparing the SSP of each distinct performance obligation to the total value of the contract. We determine the SSP based on our historical pricing and discounting practices for the distinct performance obligation when sold separately.  If the SSP is not directly observable, we estimate the SSP by considering information such as market conditions, and information about the customer. Additionally, we limit the amount of revenues recognized for delivered promises to the amount that is not contingent on future delivery of services or other future performance obligations.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Some of our customer arrangements may include an amount of variable consideration in addition to a fixed revenue share that we earn.  This variable consideration can either increase or decrease the total transaction price depending on the nature of the variable consideration.  We estimate the amount of variable consideration that we will earn at the inception of the contract, adjusted during each period, and include an estimated amount each period.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;For sales of third-party products, we evaluate whether we are acting as a principal or an agent, and therefore would record the gross sales amount as revenues and related costs or the net amount earned as a revenue share from the sale of third-party products. Our determination is based on our evaluation of whether we control the specified goods or services prior to transferring them to the customer. In relation to print textbooks owned by a partner, we recognize revenues on a net basis based on our role in the transaction as an agent as we have concluded that we do not control the use of the print textbooks, and therefore record only the net revenue share we earn.  We have concluded that we control our Chegg Services, print textbooks that we own for rental, purchase at the end of the rental term, or sale on a just-in-time basis, and eTextbook service and therefore we recognize revenues and cost of revenues on a gross basis.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Contract assets are contained within other current assets and other assets on our consolidated balance sheets.  Contract assets represent the goods or services that we have transferred to a customer before invoicing the customer and primarily consist of the income sharing payment arrangements we offer to students for our Thinkful service. Contract receivables are contained within accounts receivable, net on our consolidated balance sheets and represent unconditional consideration that will be received solely due to the passage of time. Contract liabilities are contained within deferred revenue on our consolidated balance sheets. Deferred revenue primarily consists of advanced payments from students related to rental and subscription performance obligations that have not been satisfied and estimated variable consideration. Deferred revenue related to rental and subscription performance obligations is recognized as revenues ratably over the term for subscriptions or when the services are provided and all other revenue recognition criteria have been met. Deferred revenue related to variable consideration is recognized as revenues during each reporting period based on the estimated amount we believe we will earn over the life of the contract.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We have elected a practical expedient to record incremental costs to obtain or fulfill a contract when the amortization period would have been one year or less as incurred. These incremental costs primarily relate to sales commissions costs and are recorded in sales and marketing expense on our consolidated statements of operations.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Cost of Revenues&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Our cost of revenues consists primarily of expenses associated with the delivery and distribution of our products and services. Cost of revenues primarily consists of content amortization expense related to content that we develop, license from publishers for which we pay one-time license fees, or acquire through acquisitions, payment processing costs, order fulfillment fees primarily related to outbound shipping and fulfillment as well as publisher content fees for eTextbooks, write-downs for print textbooks, the gain or loss on print textbooks liquidated, the net book value of print textbooks purchased by students at the end of the term or on a just-in-time basis, print textbook depreciation expense, personnel costs and other direct costs related to providing content or services. In addition, cost of revenues includes allocated information technology and facilities costs. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Research and Development Costs&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Our research and development expenses consist of salaries, benefits, and share-based compensation expense for employees on our product, engineering, and technical teams who are responsible for maintaining our website, developing new products, and improving existing products. Research and development costs also include depreciation expense, technology costs to support our research and development, outside services, and allocated information technology and facilities expenses. We expense substantially all of our research and development expenses as they are incurred.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Advertising Costs&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Advertising costs are expensed as incurred and consist primarily of online advertising and marketing promotional expenditures. During the&#160;years ended December 31, 2020,&#160;2019,&#160;and&#160;2018, advertising costs were approximately&#160;$35.3 million,&#160;$24.4 million, and&#160;$17.9 million, respectively.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Share-based Compensation Expense&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Share-based compensation expense for restricted stock units (RSUs), performance-based restricted stock units (PSUs), and employee stock purchase plan (ESPP) are accounted for under the fair value method, which requires us to measure the cost of share-based compensation awards based on the grant-date fair value of the award. Share-based compensation expense for our ESPP is estimated at the date of grant using the Black-Scholes-Merton option pricing model while RSUs and PSUs are measured based on the closing fair market value of the Company&#x2019;s common stock generally on the date of grant. We recognize share-based compensation expense over the requisite service period, which is generally the vesting period, on a straight-line basis for ESPP and RSUs and on a graded basis for PSUs, contingent on the achievement of performance conditions. These &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;amounts are reduced by estimated forfeitures, which are estimated at the time of the grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Income Taxes&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We account for income taxes under an asset and liability method whereby deferred tax asset and liability account balances are determined based on differences between the financial reporting and the tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Valuation allowances are established, when necessary, to reduce deferred tax assets to an amount that is more likely than not to be realized. We record uncertain tax positions on the basis of a two-step process in which (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of technical merits of the position and (2) for those tax positions that meet the more likely than not recognition threshold, we recognize the tax benefit as the largest amount that is cumulative more than 50% likely to be realized upon ultimate settlement with the related tax authority. Our policy is to include interest and penalties related to unrecognized tax benefits as a component of income tax expense.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Net Loss Per Share&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Basic net loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential shares of common stock, including stock options, RSUs, PSUs, and shares related to convertible senior notes, to the extent dilutive. Basic and diluted net loss per share was the same for each period presented as the inclusion of all potential common shares outstanding would have been anti-dilutive.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New

Upon adoption, we expect to initially record a $107&#160;million cumulative-effect adjustment to the opening balance of accumulated deficit on our consolidated balance sheet, largely due to the reduction in non-cash interest expense associated with the historical separation of debt and equity components for our notes.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Recently Adopted Accounting Pronouncements&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In March 2020, the FASB issued ASU 2020-04, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Facilitation of the Effects of Reference Rate Reform on Financial Reporting&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;.

In November 2019, the FASB issued ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments - Credit Losses. In May 2019, the FASB issued ASU 2019-05, Financial Instruments&#x2014;Credit Losses (Topic 326): Targeted Transition Relief. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments&#x2014;Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. In June 2016, the FASB issued ASU 2016-13, Financial Instruments&#x2014; Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. On January 1, 2020, we adopted ASC 326, which replaces the existing incurred loss impairment model for financial assets, including trade receivables, with an expected loss model which requires the use of forward-looking information to calculate expected credit loss estimates. Additionally, the concept of other-than-temporary impairment for available-for-sale investments is eliminated and instead requires us to focus on determining whether any unrealized loss is a result of a credit loss or other factors. We adopted ASC 326 under the modified retrospective method for all financial assets measured at amortized cost. Results for reporting periods beginning after adoption are presented under ASC 326 while we have not changed previously disclosed amounts or provided additional disclosures for comparative periods. We recorded an immaterial cumulative-effect adjustment to trade receivables to the opening balance of&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;accumulated deficit on our consolidated balance sheet. We adopted ASC 326 under the prospective transition approach for available-for-sale investments which resulted in no change to amortized cost basis before and after adoption. Credit losses related to available-for-sale investments will now be recorded through an allowance for credit losses with immediate recognition to our consolidated statement of operations rather than as a reduction to the amortized cost basis and recognition to our consolidated statements of comprehensive loss. See above within Note 1, &#x201c;Background and Basis of Presentation&#x201d;, for updates to our significant accounting policies impacted by our adoption of ASC 326 as well as Note 4, &#x201c;Cash and Cash Equivalents, and Investments&#x201d; for more information. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In August 2018, the FASB issued ASU 2018-15, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Intangibles&#x2014;Goodwill and Other&#x2014;Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;.

Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired users, acquired technology, and trade names from a market participant perspective, useful lives and discount rates. Management&#x2019;s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, which is not to exceed one year from the acquisition date, we may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill.

We completed our annual impairment test on October 1st of 2020 and 2019, each of which did not result in any impairment as our qualitative assessment did not indicate that it is more likely than not that the fair value of our reporting unit is less than the carrying amount.&lt;/span&gt;&lt;/div&gt;</us-gaap:GoodwillAndIntangibleAssetsGoodwillPolicy>

Operating leases are included in operating lease ROU assets and operating lease liabilities within current liabilities and long-term liabilities on our consolidated balance sheets. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. Our leases do not provide an implicit rate and therefore we use our incremental borrowing rate based on the information available at commencement date in determining the present value of future minimum lease payments. Our incremental borrowing rate is estimated based on the estimated rate incurred to borrow, on a collateralized basis over a similar term as our leases, an amount equal to the lease payments in a similar economic environment. Our lease &lt;/span&gt;&lt;/div&gt;terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise such options. We do not record leases on our consolidated balance sheet with a term of one year or less. We do not separate lease and non-lease components but rather account for each separate component as a single lease component for all underlying classes of assets. Some of our leases include payments that are dependent on an index, such as the Consumer Price Index (CPI), and our minimum lease payments include payments based on the index at inception with any future changes in such indices recognized as an expense in the period of change. Where leases contain escalation clauses, rent abatements, or concessions, such as rent holidays and landlord or tenant incentives or allowances, we apply them in the determination of straight-line operating lease cost over the lease term.</us-gaap:LesseeLeasesPolicyTextBlock>

In March 2019, we issued $700 million in aggregate principal amount of&#160;0.125%&#160;convertible senior notes due in 2025 (2025 notes) and in April 2019, the initial purchasers fully exercised their option to purchase $100 million of additional 2025 notes for aggregate total gross proceeds of $800 million. In April 2018, we issued&#160;$345 million in aggregate principal amount of&#160;0.25%&#160;convertible senior notes due in 2023 (2023 notes). Collectively, the 2026 notes, 2025 notes and the 2023 notes are referred to as the &#x201c;notes.&#x201d; In accounting for their issuance, we separated the notes into liability and equity components, as the notes represent convertible instruments with a cash conversion feature. The carrying amount of the liability component was calculated by measuring the fair value of similar liabilities that do not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the carrying amount of the liability component from the par value of the notes. The difference represents the debt discount, recorded as a reduction of the convertible senior notes on our consolidated balance sheet, and is amortized to interest expense over the term of the notes using the effective interest rate method. The carrying amount of the liability component is classified as a long-term liability as we have the election to settle conversion requests in shares of our common stock. The carrying amount of the equity component is not remeasured as long as it continues to meet the conditions for equity classification. In accounting for the issuance costs related to the notes, we allocated the total amount of issuance costs incurred to liability and equity components based on their relative values. Issuance costs attributable to the liability component are being amortized on a straight-line basis, which approximates the effective interest rate method, to interest expense over the term of the notes. The issuance costs attributable to the equity component are recorded as a reduction of the equity component within additional paid-in capital. In accounting for extinguishment of the notes, we allocated the consideration transferred between the liability and equity components in a similar manner as upon issuance. The liability component for extinguished notes is then compared to the carrying amount of the respective extinguished notes and a gain or loss is recorded in other income, net on our consolidated statements of operations.&lt;/span&gt;&lt;/div&gt;</us-gaap:DebtPolicyTextBlock>

We consider our print textbook library to be a long-term productive asset and, as such, classify it as a non-current asset on our consolidated balance sheets. All print textbooks in our textbook library are stated at cost, which includes the purchase price less accumulated depreciation. We write down textbooks on a book-by-book basis for lost, damaged, or excess print textbooks.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We depreciate our print textbooks, less an estimated salvage value, over an estimated useful life of four years using an accelerated method of depreciation, as we estimate this method most accurately reflects the actual pattern of decline in their economic value. The salvage value considers the historical trend and projected proceeds for print textbooks. The useful life is determined based on the estimated time period in which the print textbooks are held and rented. We review the estimated salvage value and useful life of our print textbook library on an ongoing&#160;basis. &lt;/span&gt;&lt;/div&gt;Write-downs for print textbooks, print textbook depreciation expense, the gain or loss on print textbooks liquidated, and the net book value of print textbooks purchased by students at the end of the term or on a just-in-time basis are recorded in cost of revenues on our consolidated statements of operations and classified as adjustments to cash flows from operating activities. Cash outflows for the acquisition of print textbooks net of changes in related accounts payable and accrued liabilities, and cash inflows received from the proceeds from the disposition of print textbooks net of changes in related accounts receivable, are classified as cash flows from investing activities on our consolidated statements of cash flows.</chgg:TextbookLibraryPolicyTextBlock>

We have determined these performance obligations qualify as distinct performance obligations, as the customer can benefit from the service on its own or together with other resources that are readily available to the customer, and our promise to transfer the service is separately identifiable from other promises in the contract. For these arrangements that contain multiple performance obligations, we allocate the transaction price based on the relative standalone selling price (SSP) method by comparing the SSP of each distinct performance obligation to the total value of the contract. We determine the SSP based on our historical pricing and discounting practices for the distinct performance obligation when sold separately.  If the SSP is not directly observable, we estimate the SSP by considering information such as market conditions, and information about the customer.

Our determination is based on our evaluation of whether we control the specified goods or services prior to transferring them to the customer. In relation to print textbooks owned by a partner, we recognize revenues on a net basis based on our role in the transaction as an agent as we have concluded that we do not control the use of the print textbooks, and therefore record only the net revenue share we earn.  We have concluded that we control our Chegg Services, print textbooks that we own for rental, purchase at the end of the rental term, or sale on a just-in-time basis, and eTextbook service and therefore we recognize revenues and cost of revenues on a gross basis.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Contract assets are contained within other current assets and other assets on our consolidated balance sheets.  Contract assets represent the goods or services that we have transferred to a customer before invoicing the customer and primarily consist of the income sharing payment arrangements we offer to students for our Thinkful service. Contract receivables are contained within accounts receivable, net on our consolidated balance sheets and represent unconditional consideration that will be received solely due to the passage of time. Contract liabilities are contained within deferred revenue on our consolidated balance sheets. Deferred revenue primarily consists of advanced payments from students related to rental and subscription performance obligations that have not been satisfied and estimated variable consideration. Deferred revenue related to rental and subscription performance obligations is recognized as revenues ratably over the term for subscriptions or when the services are provided and all other revenue recognition criteria have been met. Deferred revenue related to variable consideration is recognized as revenues during each reporting period based on the estimated amount we believe we will earn over the life of the contract.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We have elected a practical expedient to record incremental costs to obtain or fulfill a contract when the amortization period would have been one year or less as incurred.

Valuation allowances are established, when necessary, to reduce deferred tax assets to an amount that is more likely than not to be realized. We record uncertain tax positions on the basis of a two-step process in which (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of technical merits of the position and (2) for those tax positions that meet the more likely than not recognition threshold, we recognize the tax benefit as the largest amount that is cumulative more than 50% likely to be realized upon ultimate settlement with the related tax authority.

The guidance allows for a modified retrospective method of transition with a cumulative-effect adjustment to the opening balance sheet of accumulated deficit in the period of adoption without restating prior periods. The guidance is effective for fiscal years beginning after December 15, 2021, with early adoption permitted no earlier than fiscal years beginning after December 15, 2020. We will early adopt the guidance on January 1, 2021 under the modified retrospective method of transition. Upon adoption, we expect to initially record a $107&#160;million cumulative-effect adjustment to the opening balance of accumulated deficit on our consolidated balance sheet, largely due to the reduction in non-cash interest expense associated with the historical separation of debt and equity components for our notes.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Recently Adopted Accounting Pronouncements&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In March 2020, the FASB issued ASU 2020-04, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Facilitation of the Effects of Reference Rate Reform on Financial Reporting&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;. ASU 2020-04 provides temporary optional expedients and exceptions for applying reference rate reform to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The guidance is required to be applied immediately and only applies to contract modifications made or hedging relationships entered into or evaluated before December 31, 2022.

ASU 2019-12 key changes include hybrid tax regimes, intraperiod tax allocation exception, and interim-period accounting for enacted changes in tax law.

In November 2019, the FASB issued ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments - Credit Losses. In May 2019, the FASB issued ASU 2019-05, Financial Instruments&#x2014;Credit Losses (Topic 326): Targeted Transition Relief. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments&#x2014;Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. In June 2016, the FASB issued ASU 2016-13, Financial Instruments&#x2014; Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. On January 1, 2020, we adopted ASC 326, which replaces the existing incurred loss impairment model for financial assets, including trade receivables, with an expected loss model which requires the use of forward-looking information to calculate expected credit loss estimates. Additionally, the concept of other-than-temporary impairment for available-for-sale investments is eliminated and instead requires us to focus on determining whether any unrealized loss is a result of a credit loss or other factors. We adopted ASC 326 under the modified retrospective method for all financial assets measured at amortized cost. Results for reporting periods beginning after adoption are presented under ASC 326 while we have not changed previously disclosed amounts or provided additional disclosures for comparative periods. We recorded an immaterial cumulative-effect adjustment to trade receivables to the opening balance of&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;accumulated deficit on our consolidated balance sheet. We adopted ASC 326 under the prospective transition approach for available-for-sale investments which resulted in no change to amortized cost basis before and after adoption. Credit losses related to available-for-sale investments will now be recorded through an allowance for credit losses with immediate recognition to our consolidated statement of operations rather than as a reduction to the amortized cost basis and recognition to our consolidated statements of comprehensive loss. See above within Note 1, &#x201c;Background and Basis of Presentation&#x201d;, for updates to our significant accounting policies impacted by our adoption of ASC 326 as well as Note 4, &#x201c;Cash and Cash Equivalents, and Investments&#x201d; for more information. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In August 2018, the FASB issued ASU 2018-15, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Intangibles&#x2014;Goodwill and Other&#x2014;Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;.

During the year ended December&#160;31, 2020, our deferred revenue balance increased by $13.8 &lt;/span&gt;&lt;/div&gt;million, or 74%, primarily due to increased bookings driven by higher Chegg Services revenue and print textbooks that we own that are recognized ratably rather than immediately. During the year ended December&#160;31, 2020, our contract assets balance increased by $9.7 million or 275%, primarily due to the income sharing payment arrangements we offer to students for our Thinkful service.</us-gaap:RevenueFromContractWithCustomerTextBlock>

consider the declines in market value of our investment portfolio to be driven by credit related factors. When evaluating whether an investment's unrealized losses are related to credit factors, we review factors such as the extent to which fair value is below its cost basis, any changes to the credit rating of the security, adverse conditions specifically related to the security, changes in market interest rates and our intent to sell, or whether it is more likely than not we will be required to sell, before recovery of cost basis. We invest in highly-rated securities with a minimum credit rating of A- and a weighted average maturity of&#160;less than twelve months, and our investment policy limits the amount of credit exposure to any one issuer or industry sector. The policy requires investments generally to be investment grade, with the primary objective of preserving capital and maintaining liquidity. Fair values were determined for each individual security in the investment portfolio. During the&#160;year ended December&#160;31, 2020, we did not recognize any losses on our investments due to credit related factors. During the years ended December&#160;31, 2019 and 2018, we did not recognize any impairment charges.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Strategic Investments&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In March 2020, we completed an investment of $2.0&#160;million in TAPD, Inc., also known as Frank, a U.S.-based service that helps students access financial aid. In October 2018, we completed an investment of $10.0&#160;million in WayUp, Inc. (WayUp), a U.S.-based job site and mobile application for college students and recent graduates. Additionally, we previously invested&#160;$3.0 million&#160;in a foreign entity to explore expanding our reach internationally. During the year ended December&#160;31, 2020, we recorded a $10.0&#160;million impairment charge on our investment in WayUp included within general and administrative expense on our consolidated statements of operations. Our impairment assessment was the result of the uncertainty around WayUp's ability to raise additional funding to support their future operations. We did not record any other impairment charges on our other strategic investments during the years ended December 31, 2020, 2019 and&#160;2018, as there were no other significant identified events or changes in circumstances that would be considered an indicator for impairment. We considered general market conditions as a result of the COVID-19 pandemic in our impairment analysis. There were no observable price changes in orderly transactions for the identical or similar investments of the same issuers that resulted in an upward or downward adjustment on our strategic investments during the years ended December&#160;31, 2020, 2019 and 2018.&lt;/span&gt;&lt;/div&gt;</us-gaap:InvestmentsInDebtAndEquityInstrumentsCashAndCashEquivalentsUnrealizedAndRealizedGainsLossesTextBlock>

(Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. Other than our money market funds and U.S. treasury securities, we classify our fixed income available-for-sale investments as having Level 2 inputs. The valuation techniques used to measure the fair value of our investments having Level 2 inputs were derived from non-binding market consensus prices that are corroborated by observable market data, quoted market prices for similar instruments, or pricing models such as discounted cash flow techniques. We do not hold any investments valued with a Level 3 input.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while we believe our valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Financial Instruments Not Recorded at Fair Value on a Recurring Basis&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We report our financial instruments at fair value with the exception of the notes. The estimated fair value of the notes was determined based on the trading price of the notes as of the last day of trading for the period. We consider the fair value of the notes to be a Level 2 measurement due to the limited trading activity. For further information on the notes see Note 10, &#x201c;Convertible Senior Notes.&#x201d;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times

This acquisition helps to strengthen our existing Chegg Math Solver service with the addition of new subjects, languages, and international reach. The total fair value of the purchase consideration was $101.0&#160;million, of which $93.5&#160;million was paid in cash on the acquisition date and $7.5&#160;million, included within accrued liabilities, was held in escrow as security for general representations and warranties and potential post-closing adjustments. Any remaining escrow amount will be released 15 months after the acquisition date.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Mathway purchase agreement provides for additional payments of up to $15.0&#160;million subject to the achievement of specified milestones and continued employment of the sellers. These payments are not included in the fair value of the purchase consideration but rather are expensed ratably as acquisition-related compensation costs classified as research and development and general and administrative expenses, based on the seller's job function, on our consolidated statement of operations. We have recorded approximately $2.9&#160;million as of December&#160;31, 2020, included within accrued liabilities on our consolidated balance sheet for these payments.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New

We have recorded immaterial amounts of revenue and earnings from Mathway since the acquisition date.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The following unaudited supplemental pro forma net loss is for informational purposes only and presents our combined results as if the acquisition of Mathway had occurred on January 1, 2019. The unaudited supplemental pro forma information includes the historical combined operating results adjusted for acquisition-related compensation costs, amortization of intangible assets, share-based compensation expense and acquisition-related expenses and does not necessarily reflect the actual results that would have been achieved, nor is it necessarily indicative of our future consolidated results. During the years ended December 31, 2020 and 2019, our supplemental pro forma net loss would have been $6.1&#160;million and $27.3&#160;million, respectively. Revenues from Mathway were immaterial during the years ended December 31, 2020 and 2019.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;2019 Acquisition&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;On&#160;October 1, 2019, we completed our acquisition of Thinkful, Inc. (Thinkful), our skills-based learning platform that offers professional courses in software engineering, UX/UI design, digital marketing, data science, product management, data analytics, product design, and technical project management directly to students across the United States to expand our existing offerings by adding affordable and high-quality courses focused on the most in-demand technology skills. The total fair value of the purchase consideration was $79.2 million, which was paid in cash and included an escrow amount of $9.0 million for general representations and warranties and potential post-closing adjustments. Any remaining escrow amount will be released 18 months after the acquisition date.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Included in the purchase agreement for the acquisition of Thinkful are additional payments of up to $20.0 million subject to the achievement of specified milestones and continued employment of key employees. These payments are not included in the fair value of the purchase consideration and are expensed ratably as acquisition related compensation costs classified as research and development, general and administrative, and sales and marketing expenses, based on the key employee's job function, on our consolidated statement of operations. These payments may be settled by us, at our sole discretion, either in cash or shares of our common stock. During the year ended December&#160;31, 2020, the terms of the purchase agreement were amended such that the retention incentive was reduced to $12.8&#160;million, half of which remains subject to the achievement of specified milestones and payable in cash and half of which will be settled in equity grants, to adjust for employee departures. As of December&#160;31, 2020 and 2019, we have recorded approximately $5.7 million and $3.0&#160;million, respectively, included within accrued liabilities on our consolidated balance sheet for the cash payments.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Goodwill is primarily attributable to the potential for expanding our existing offerings and reach by providing educational services for students and helping them through their professional journey.

The unaudited supplemental pro forma information includes the historical combined operating results adjusted for acquisition related compensation costs, amortization of intangible assets, share-based compensation expense and transaction expenses and does not necessarily reflect the actual results that would have been achieved, nor is it necessarily indicative of our future consolidated results. During the years ended December 31, 2019 and 2018, our supplemental pro forma net loss would have been $25.0 million and $38.6 million, respectively.

This acquisition helps strengthen our existing Chegg Services offerings by adding a substantial number of subject categories and a library of content to our learning platform. The total fair value of the purchase consideration was $20.4 million, which included an escrow amount of $3.3 million for general representations and warranties and post-closing adjustments, which was released in January 2020.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;On&#160;May 15, 2018, we acquired WriteLab, Inc. (WriteLab), an AI-enhanced writing platform that teaches students grammar, sentence structure, writing style, and offers instant feedback to help students revise, edit, and improve their written work. This acquisition helps to strengthen Chegg Writing with the addition of new tools, features, and functionality. The total fair value of the purchase consideration was $14.5 million, which included an escrow amount of $2.6 million for general representations and warranties and potential post-closing adjustments, which was released in January 2020. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Included in the purchase agreement for the acquisition of WriteLab are additional payments of up to $5.0 million subject to continued employment of the sellers. These payments are not included in the fair value of the purchase consideration and are expensed ratably as research and development expenses on our consolidated statement of operations. These payments may be settled by us, at our sole discretion, either in cash or shares of our common stock. We have recorded approximately $1.0 million as of December&#160;31, 2020 and 2019 included within accrued liabilities on our consolidated balance sheet for these payments. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Goodwill is primarily attributable to the potential for future product offerings as well as our expanded student reach.

The fair value of the liability component was calculated by measuring the fair value of similar debt instruments that do not have an associated convertible feature. The carrying amount of the liability component of the 2023 notes subject to the extinguishment was $51.6&#160;million resulting in a $1.0&#160;million loss on early extinguishment which was recorded in other income, net on our consolidated statements of operations.

The first circumstance allowing holders of the 2025 notes to convert was met during the three months ended December 31, 2020 and September 30, 2020 and therefore, the 2025 notes are convertible starting October 1, 2020 through March 31, 2021. During the year ended December&#160;31, 2020, we received an immaterial request for conversion of the 2025 notes which we intend to settle in cash during the three months ended March 31, 2021. The first circumstance allowing holders of the 2023 notes to convert was met during the three months ended December 31, 2020, September 30, 2020, June 30, 2020, March 31, 2020, December 31, 2019, June 30, 2019, and March 31, 2019 and therefore, the 2023 notes were and are convertible starting April 1, 2019 through September 30, 2019 and from January 1, 2020 through March 31, 2021. During the year ended December&#160;31, 2020, aside from the exchange of $172.0&#160;million and extinguishments of $57.4&#160;million aggregate principal &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;amount of the 2023 notes discussed above, we received immaterial requests for conversion of the 2023 notes which we settled in cash during the year ended December&#160;31, 2020 and intend to settle during the three months ended March 31, 2021. After December&#160;31, 2020 and through the date of issuance of this Annual Report on Form 10-K, we received $24.7&#160;million aggregate principal amount requests for conversion of the 2023 Notes, which we intend to settle through a combination of cash and shares of our common stock during the first half of 2021.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In accounting for their issuance, we separated the notes into liability and equity components. The carrying amount of the liability components for the 2026 notes, 2025 notes and 2023 notes of approximately $758.7 million, $588.0 million and $280.8 million, respectively, was calculated by measuring the fair value of similar debt instruments that do not have an associated convertible feature. The carrying amount of the equity components for the 2026 notes, 2025 notes and 2023 notes of approximately $241.3 million, $212.0 million and $64.2 million, respectively, representing the conversion option, was determined by deducting the carrying amount of the liability components from the principal amount of the notes. This difference between the principal amount of the notes and the liability components represents the debt discount, presented as a reduction to the notes on our consolidated balance sheets, and is amortized to interest expense using the effective interest method over the remaining term of the notes. The equity components of the notes are included in additional paid-in capital on our consolidated balance sheets and are not remeasured as long as they continue to meet the conditions for equity classification.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We incurred issuance costs related to the 2026 notes, 2025 notes and 2023 notes of approximately $15.9 million, $19.8 million, and $9.4 million, respectively. In accounting for the issuance costs, we allocated the total amount incurred to the liability and equity components using the same proportions determined above for the notes. Issuance costs attributable to the liability components for the 2026 notes, 2025 notes and 2023 notes of approximately $12.1 million, $14.6 million and $7.6 million, respectively, were recorded as debt issuance cost, presented as a reduction to the notes on our consolidated balance sheets, and are amortized to interest expense using the effective interest method over the term of the notes. The issuance costs attributable to the equity components for the 2026 notes, 2025 notes and 2023 notes were approximately $3.8 million, $5.3 million and $1.7 million, respectively, and were recorded as a reduction to the equity component included in additional paid-in capital.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div

Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Concurrently with the offering of the 2026 notes, 2025 notes and 2023 notes, we used $103.4 million, $97.2 million and $39.2 million, respectively, of the net proceeds to enter into privately negotiated capped call transactions which are expected to generally reduce or offset potential dilution to holders of our common stock upon conversion of the notes and/or offset the potential cash payments we would be required to make in excess of the principal amount of any converted notes. The capped call transactions automatically exercise upon conversion of the notes and cover 9,297,800, 15,516,480 and 4,288,459 shares of our common stock for the 2026 notes, 2025 notes and 2023 notes, respectively, and are intended to effectively increase the overall conversion price from&#160;$107.55 to $156.44 per share for the 2026 notes, $51.56 to $79.32 per share for the 2025 notes and $26.95&#160;to&#160;$40.68&#160;per share for the 2023 notes. The effective increase in conversion price as a result of the capped call transactions serves to reduce potential dilution to holders of our common stock and/or offset the cash payments we are required to make in excess of the principal amount of any converted notes. As these transactions meet certain accounting criteria, they are recorded in stockholders&#x2019; equity as a reduction of additional paid-in capital on our consolidated balance sheets and are not accounted for as derivatives. The fair value of the capped call instrument is not remeasured each reporting period. The cost of the capped call is not expected to be deductible for tax purposes.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Impact to Earnings per Share&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:24.75pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The shares underlying the notes have no impact to diluted earnings per share until the average price of our common stock during the period exceeds the conversion price&#160;for the 2026 notes, 2025 notes and 2023 notes of $107.55, $51.56 and $26.95 per share, respectively, and the conversion circumstances have been met. Under the treasury stock method, in periods we report net income, we are required to include the effect of additional shares that may be issued under the notes when the average price of our common stock exceeds each respective conversion price. However, as a result of the capped call transactions described above, there will be no economic dilution from the 2026 notes,  2025 notes and 2023 notes up to $156.44, $79.32 and $40.68, respectively, as exercise of the capped call instruments will reduce any dilution from the notes that would have otherwise occurred when the average price of our common stock exceeds the conversion price.&lt;/span&gt;&lt;/div&gt;</us-gaap:DebtDisclosureTextBlock>

approved by our stockholders on August&#160;29, 2013. The 2013 Plan became effective on November&#160;11, 2013 and replaced the 2005 Plan. On the effective date of the 2013 Plan,&#160;12,000,000&#160;shares of our common stock were reserved for issuance, plus an additional&#160;3,838,985&#160;shares reserved but not issued or subject to outstanding awards under our 2005 Plan on the effective date of the 2013 Plan, plus, on and after the effective date of the 2013 Plan, (i)&#160;shares that are subject to outstanding awards under the 2005 Plan which cease to be subject to such awards, (ii)&#160;shares issued under the 2005 Plan that are forfeited or repurchased at their original issue price and (iii)&#160;shares subject to awards under the 2005 Plan that are used to pay the exercise price of an option or withheld to satisfy the tax withholding obligations related to any award. As of&#160;December&#160;31, 2020,&#160;there were&#160;29,158,085&#160;shares available for grant under the 2013 Plan. The 2013 Plan permits the granting of incentive stock options, non-qualified stock options, RSUs, stock appreciation rights, restricted shares of common stock and performance share awards. The exercise price of stock options may not be less than the&#160;100%&#160;of the fair market value of the common stock on the date of grant. Options granted pursuant to the 2013 Plan generally expire no later than&#160;10&#160;years.&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;2013 Employee Stock Purchase Plan&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:27pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;On June&#160;6, 2013, our Board of Directors adopted our 2013 Employee Stock Purchase Plan (the 2013 ESPP) and our stockholders subsequently approved the 2013 ESPP Plan on August&#160;29, 2013. The 2013 ESPP permits eligible employees to acquire shares of our common stock by accumulating funds through periodic payroll deductions of up to&#160;15%&#160;of base salary. Our 2013 ESPP is intended to qualify as an ESPP under Section&#160;423 of the Code and employees will receive a&#160;15%&#160;discount to the lesser of the fair market value of our common stock on (i)&#160;the first trading day of the applicable offering period or (ii)&#160;the last day of each purchase period in the applicable offering period. Each offering period may run for no more than&#160;six months. We have reserved&#160;4,000,000&#160;shares of our common stock under our 2013 ESPP. The aggregate number of shares issued over the term of our 2013 ESPP will not exceed&#160;20,000,000&#160;shares of our common stock. As of&#160;December&#160;31, 2020, there were&#160;8,688,210&#160;shares of common stock available for future issuance under the 2013 ESPP.&lt;/span&gt;&lt;/div&gt;</chgg:CommonStockTextBlock>

recognized, that would affect the effective tax rate is&#160;$3.4 million for the year ended December&#160;31, 2020. One or more of these unrecognized tax benefits could be subject to a valuation allowance if, and when recognized in a future period, which could impact the timing of any related effective tax rate benefit.&lt;/span&gt;&lt;/div&gt;The actual amount of any taxes due could vary significantly depending on the ultimate timing and nature of any settlement. We believe that the amount by which the unrecognized tax benefits may increase or decrease within the next 12 months is not estimable.</us-gaap:IncomeTaxDisclosureTextBlock>

In March 2019, we issued $700 million in aggregate principal amount of&#160;0.125%&#160;convertible senior notes due in 2025 (2025 notes) and in April 2019, the initial purchasers fully exercised their option to purchase $100 million of additional 2025 notes for aggregate total gross proceeds of $800 million. In April 2018, we issued&#160;$345 million in aggregate principal amount of&#160;0.25%&#160;convertible senior notes due in 2023 (2023 notes). Collectively, the 2026 notes, 2025 notes and the 2023 notes are referred to as the &#8220;notes.&#8221; In accounting for their issuance, we separated the notes into liability and equity components, as the notes represent convertible instruments with a cash conversion feature. The carrying amount of the liability component was calculated by measuring the fair value of similar liabilities that do not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the carrying amount of the liability component from the par value of the notes. The difference represents the debt discount, recorded as a reduction of the convertible senior notes on our consolidated balance sheet, and is amortized to interest expense over the term of the notes using the effective interest rate method. The carrying amount of the liability component is classified as a long-term liability as we have the election to settle conversion requests in shares of our common stock. The carrying amount of the equity component is not remeasured as long as it continues to meet the conditions for equity classification. In accounting for the issuance costs related to the notes, we allocated the total amount of issuance costs incurred to liability and equity components based on their relative values. Issuance costs attributable to the liability component are being amortized on a straight-line basis, which approximates the effective interest rate method, to interest expense over the term of the notes. The issuance costs attributable to the equity component are recorded as a reduction of the equity component within additional paid-in capital. In accounting for extinguishment of the notes, we allocated the consideration transferred between the liability and equity components in a similar manner as upon issuance. The liability component for extinguished notes is then compared to the carrying amount of the respective extinguished notes and a gain or loss is recorded in other income, net on our consolidated statements of operations.</span></div><div style="text-indent:27pt"><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Textbook Library</span></div><div><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Beginning in January 2020, we began our transition back to print textbook ownership by purchasing print textbooks to establish our textbook library.

Additionally, we limit the amount of revenues recognized for delivered promises to the amount that is not contingent on future delivery of services or other future performance obligations.</span></div><div style="text-indent:27pt"><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Some of our customer arrangements may include an amount of variable consideration in addition to a fixed revenue share that we earn.  This variable consideration can either increase or decrease the total transaction price depending on the nature of the variable consideration.  We estimate the amount of variable consideration that we will earn at the inception of the contract, adjusted during each period, and include an estimated amount each period.</span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">For sales of third-party products, we evaluate whether we are acting as a principal or an agent, and therefore would record the gross sales amount as revenues and related costs or the net amount earned as a revenue share from the sale of third-party products. Our determination is based on our evaluation of whether we control the specified goods or services prior to transferring them to the customer. In relation to print textbooks owned by a partner, we recognize revenues on a net basis based on our role in the transaction as an agent as we have concluded that we do not control the use of the print textbooks, and therefore record only the net revenue share we earn.  We have concluded that we control our Chegg Services, print textbooks that we own for rental, purchase at the end of the rental term, or sale on a just-in-time basis, and eTextbook service and therefore we recognize revenues and cost of revenues on a gross basis.</span></div><div style="text-indent:27pt"><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Contract assets are contained within other current assets and other assets on our consolidated balance sheets.  Contract assets represent the goods or services that we have transferred to a customer before invoicing the customer and primarily consist of the income sharing payment arrangements we offer to students for our Thinkful service. Contract receivables are contained within accounts receivable, net on our consolidated balance sheets and represent unconditional consideration that will be received solely due to the passage of time. Contract liabilities are contained within deferred revenue on our consolidated balance sheets. Deferred revenue primarily consists of advanced payments from students related to rental and subscription performance obligations that have not been satisfied and estimated variable consideration. Deferred revenue related to rental and subscription performance obligations is recognized as revenues ratably over the term for subscriptions or when the services are provided and all other revenue recognition criteria have been met. Deferred revenue related to variable consideration is recognized as revenues during each reporting period based on the estimated amount we believe we will earn over the life of the contract.</span></div><div style="text-indent:27pt"><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We have elected a practical expedient to record incremental costs to obtain or fulfill a contract when the amortization period would have been one year or less as incurred.

Valuation allowances are established, when necessary, to reduce deferred tax assets to an amount that is more likely than not to be realized. We record uncertain tax positions on the basis of a two-step process in which (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of technical merits of the position and (2) for those tax positions that meet the more likely than not recognition threshold, we recognize the tax benefit as the largest amount that is cumulative more than 50% likely to be realized upon ultimate settlement with the related tax authority.

In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments&#8212;Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. In June 2016, the FASB issued ASU 2016-13, Financial Instruments&#8212; Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. On January 1, 2020, we adopted ASC 326, which replaces the existing incurred loss impairment model for financial assets, including trade receivables, with an expected loss model which requires the use of forward-looking information to calculate expected credit loss estimates. Additionally, the concept of other-than-temporary impairment for available-for-sale investments is eliminated and instead requires us to focus on determining whether any unrealized loss is a result of a credit loss or other factors. We adopted ASC 326 under the modified retrospective method for all financial assets measured at amortized cost. Results for reporting periods beginning after adoption are presented under ASC 326 while we have not changed previously disclosed amounts or provided additional disclosures for comparative periods.

of&#160;December&#160;31, 2020, we did not consider the declines in market value of our investment portfolio to be driven by credit related factors. When evaluating whether an investment's unrealized losses are related to credit factors, we review factors such as the extent to which fair value is below its cost basis, any changes to the credit rating of the security, adverse conditions specifically related to the security, changes in market interest rates and our intent to sell, or whether it is more likely than not we will be required to sell, before recovery of cost basis. We invest in highly-rated securities with a minimum credit rating of A- and a weighted average maturity of&#160;less than twelve months, and our investment policy limits the amount of credit exposure to any one issuer or industry sector. The policy requires investments generally to be investment grade, with the primary objective of preserving capital and maintaining liquidity. Fair values were determined for each individual security in the investment portfolio. During the&#160;year ended December&#160;31, 2020, we did not recognize any losses on our investments due to credit related factors. During the years ended December&#160;31, 2019 and 2018, we did not recognize any impairment charges.</span></div><div style="text-indent:27pt"><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Strategic Investments</span></div><div><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In March 2020, we completed an investment of $2.0&#160;million in TAPD, Inc., also known as Frank, a U.S.-based service that helps students access financial aid. In October 2018, we completed an investment of $10.0&#160;million in WayUp, Inc. (WayUp), a U.S.-based job site and mobile application for college students and recent graduates. Additionally, we previously invested&#160;$3.0 million&#160;in a foreign entity to explore expanding our reach internationally. During the year ended December&#160;31, 2020, we recorded a $10.0&#160;million impairment charge on our investment in WayUp included within general and administrative expense on our consolidated statements of operations. Our impairment assessment was the result of the uncertainty around WayUp's ability to raise additional funding to support their future operations. We did not record any other impairment charges on our other strategic investments during the years ended December 31, 2020, 2019 and&#160;2018, as there were no other significant identified events or changes in circumstances that would be considered an indicator for impairment. We considered general market conditions as a result of the COVID-19 pandemic in our impairment analysis. There were no observable price changes in orderly transactions for the identical or similar investments of the same issuers that resulted in an upward or downward adjustment on our strategic investments during the years ended December&#160;31, 2020, 2019 and 2018.</span></div><span></span>

This acquisition helps to strengthen our existing Chegg Math Solver service with the addition of new subjects, languages, and international reach. The total fair value of the purchase consideration was $101.0&#160;million, of which $93.5&#160;million was paid in cash on the acquisition date and $7.5&#160;million, included within accrued liabilities, was held in escrow as security for general representations and warranties and potential post-closing adjustments.

These payments may be settled by us, at our sole discretion, either in cash or shares of our common stock. During the year ended December&#160;31, 2020, the terms of the purchase agreement were amended such that the retention incentive was reduced to $12.8&#160;million, half of which remains subject to the achievement of specified milestones and payable in cash and half of which will be settled in equity grants, to adjust for employee departures.

notes and 2023 notes, we used $103.4 million, $97.2 million and $39.2 million, respectively, of the net proceeds to enter into privately negotiated capped call transactions which are expected to generally reduce or offset potential dilution to holders of our common stock upon conversion of the notes and/or offset the potential cash payments we would be required to make in excess of the principal amount of any converted notes. The capped call transactions automatically exercise upon conversion of the notes and cover 9,297,800, 15,516,480 and 4,288,459 shares of our common stock for the 2026 notes, 2025 notes and 2023 notes, respectively, and are intended to effectively increase the overall conversion price from&#160;$107.55 to $156.44 per share for the 2026 notes, $51.56 to $79.32 per share for the 2025 notes and $26.95&#160;to&#160;$40.68&#160;per share for the 2023 notes. The effective increase in conversion price as a result of the capped call transactions serves to reduce potential dilution to holders of our common stock and/or offset the cash payments we are required to make in excess of the principal amount of any converted notes. As these transactions meet certain accounting criteria, they are recorded in stockholders&#8217; equity as a reduction of additional paid-in capital on our consolidated balance sheets and are not accounted for as derivatives. The fair value of the capped call instrument is not remeasured each reporting period. The cost of the capped call is not expected to be deductible for tax purposes.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Impact to Earnings per Share</span></div><div style="text-indent:24.75pt"><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The shares underlying the notes have no impact to diluted earnings per share until the average price of our common stock during the period exceeds the conversion price&#160;for the 2026 notes, 2025 notes and 2023 notes of $107.55, $51.56 and $26.95 per share, respectively, and the conversion circumstances have been met. Under the treasury stock method, in periods we report net income, we are required to include the effect of additional shares that may be issued under the notes when the average price of our common stock exceeds each respective conversion price. However, as a result of the capped call transactions described above, there will be no economic dilution from the 2026 notes,  2025 notes and 2023 notes up to $156.44, $79.32 and $40.68, respectively, as exercise of the capped call instruments will reduce any dilution from the notes that would have otherwise occurred when the average price of our common stock exceeds the conversion price.</span></div><span></span>

The exercise price of stock options may not be less than the&#160;100%&#160;of the fair market value of the common stock on the date of grant.

Significant estimates, assumptions, and judgments are used for, but not limited to: revenue recognition, recoverability of accounts receivable, share-based compensation expense including estimated forfeitures, accounting for income taxes, useful lives and salvage value assigned to our textbook library, useful lives assigned to long-lived assets for depreciation and amortization, impairment of goodwill and long-lived assets, the valuation of acquired intangible assets, the valuation of our convertible senior notes, internal-use software and website development costs, operating lease right of use (ROU) assets, and operating lease liabilities. We base our estimates on historical experience, knowledge of current business conditions, and various other factors we believe to be reasonable under the circumstances. These estimates are based on management&#8217;s knowledge about current events and expectations about actions we may undertake in the future. Actual results could differ from these estimates, and such differences could be material to our financial position and results of operations.</span></div><span></span>

In April 2018, we issued&#160;$345 million in aggregate principal amount of&#160;0.25%&#160;convertible senior notes due in 2023 (2023 notes). Collectively, the 2026 notes, 2025 notes and the 2023 notes are referred to as the &#8220;notes.&#8221; In accounting for their issuance, we separated the notes into liability and equity components, as the notes represent convertible instruments with a cash conversion feature. The carrying amount of the liability component was calculated by measuring the fair value of similar liabilities that do not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the carrying amount of the liability component from the par value of the notes. The difference represents the debt discount, recorded as a reduction of the convertible senior notes on our consolidated balance sheet, and is amortized to interest expense over the term of the notes using the effective interest rate method. The carrying amount of the liability component is classified as a long-term liability as we have the election to settle conversion requests in shares of our common stock. The carrying amount of the equity component is not remeasured as long as it continues to meet the conditions for equity classification. In accounting for the issuance costs related to the notes, we allocated the total amount of issuance costs incurred to liability and equity components based on their relative values. Issuance costs attributable to the liability component are being amortized on a straight-line basis, which approximates the effective interest rate method, to interest expense over the term of the notes. The issuance costs attributable to the equity component are recorded as a reduction of the equity component within additional paid-in capital. In accounting for extinguishment of the notes, we allocated the consideration transferred between the liability and equity components in a similar manner as upon issuance. The liability component for extinguished notes is then compared to the carrying amount of the respective extinguished notes and a gain or loss is recorded in other income, net on our consolidated statements of operations.</span></div><span></span>

We have determined these performance obligations qualify as distinct performance obligations, as the customer can benefit from the service on its own or together with other resources that are readily available to the customer, and our promise to transfer the service is separately identifiable from other promises in the contract. For these arrangements that contain multiple performance obligations, we allocate the transaction price based on the relative standalone selling price (SSP) method by comparing the SSP of each distinct performance obligation to the total value of the contract. We determine the SSP based on our historical pricing and discounting practices for the distinct performance obligation when sold separately.  If the SSP is not directly observable, we estimate the SSP by considering information such as market conditions, and information about the customer. Additionally, we limit the amount of revenues recognized for delivered promises to the amount that is not contingent on future delivery of services or other future performance obligations.</span></div><div style="text-indent:27pt"><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Some of our customer arrangements may include an amount of variable consideration in addition to a fixed revenue share that we earn.

Our determination is based on our evaluation of whether we control the specified goods or services prior to transferring them to the customer. In relation to print textbooks owned by a partner, we recognize revenues on a net basis based on our role in the transaction as an agent as we have concluded that we do not control the use of the print textbooks, and therefore record only the net revenue share we earn.  We have concluded that we control our Chegg Services, print textbooks that we own for rental, purchase at the end of the rental term, or sale on a just-in-time basis, and eTextbook service and therefore we recognize revenues and cost of revenues on a gross basis.</span></div><div style="text-indent:27pt"><span><br/></span></div><div style="text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Contract assets are contained within other current assets and other assets on our consolidated balance sheets.

Contract liabilities are contained within deferred revenue on our consolidated balance sheets. Deferred revenue primarily consists of advanced payments from students related to rental and subscription performance obligations that have not been satisfied and estimated variable consideration. Deferred revenue related to rental and subscription performance obligations is recognized as revenues ratably over the term for subscriptions or when the services are provided and all other revenue recognition criteria have been met.

Additionally, the concept of other-than-temporary impairment for available-for-sale investments is eliminated and instead requires us to focus on determining whether any unrealized loss is a result of a credit loss or other factors. We adopted ASC 326 under the modified retrospective method for all financial assets measured at amortized cost.

The excess of the carrying amount over the fair value of the investment represents the amount of the write down which is or was reflected in earnings. The written down value is a new cost basis with the adjusted value of the investment becoming its new carrying value subject to the equity accounting method. Evidence of a loss in value might include, but would not necessarily be limited to, absence of an ability to recover the carrying amount of the investment or inability of the investee to sustain an earnings capacity which would justify the carrying amount of the investment.</p></div>
