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 financial institutions are in excess of Federal Deposit Insurance Corporation limits. Our investment portfolio consists of investment-grade marketable securities 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.<br clear="none"/> <br clear="none"/></font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">C</font></div></div>

Revenues are recognized when the four basic criteria for revenue recognition have been met as follows: persuasive evidence of an arrangement exists, delivery has occurred and title has transferred, the sale price is fixed or determinable, and collection is reasonably assured.</font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Revenues are presented net of sales tax collected from customers to be remitted to governmental authorities and net of allowances for estimated cancellations and customer returns, which are based on historical data. Customer refunds from cancellations and returns are recorded as a reduction to revenues. </font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We generate revenues from our Required Materials product line including the rental of print textbooks and eTextbooks and, to a lesser extent, through the sales of print textbooks through our website purchased by us on a just-in-time basis. Rental revenues were historically recognized ratably over the term of the rental period, generally two to five months, for the print textbooks that we owned. </font><font style="font-family:inherit;font-size:10pt;">As of November 2016, we no longer rent our print textbooks and therefore all revenues from print textbook rentals from this date forward are commission-based.</font><font style="font-family:inherit;font-size:10pt;"> Commission-based print textbook rental revenues are recognized immediately in the period the transaction occurs. Revenues from selling textbooks on a just-in-time basis are recognized upon shipment. We do not hold an inventory of textbooks for sale. Our customers pay for the rental and sale of print textbooks on our website primarily by credit card, resulting in immediate settlement of our accounts receivable. Shipping costs charged to customers in the sale or rental of textbooks are recorded in revenues and the related expenses are recorded as cost of revenues.</font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We generate revenues from our Chegg Services product line including our Chegg Study service, our Chegg Tutors service, and our writing tools service that we offer to students. These services are offered to students through monthly or annual subscriptions and we recognize revenues ratably over the respective subscription period. Our Chegg Services also include enrollment marketing services and brand advertising, which we offer either on a subscription or on an a la carte basis. Enrollment marketing services connect colleges and graduate schools with students seeking admission or scholarship opportunities at these institutions. Brand advertising offers brands unique ways to connect with students. Finally, Chegg Services includes our internship services and our Test Prep service currently covering the ACT and SAT exams. Revenues are recognized ratably or as earned over the subscription service, generally one year. Revenues from enrollment marketing services or brand advertising delivered on an a la carte basis, without a subscription, is recognized when delivery of the respective lead or service has occurred. For these services, we bill the customer at the inception, over the term of the customer arrangement or as the services are performed. Upon satisfactory assessment of creditworthiness, we generally grant credit to our enrollment marketing services and brand advertising customers with normal credit terms, typically 30 days.</font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Some of our customer arrangements for enrollment marketing services include multiple deliverables, which include the delivery of student leads as well as other services to the end customer. We have determined these deliverables qualify as separate units of accounting, as they have value to the customer on a standalone basis and our arrangements do not contain a right of return. For these arrangements that contain multiple deliverables, we allocate the arrangement consideration based on the relative selling price method in accordance with the selling price hierarchy, which includes: (1) vendor-specific objective evidence of fair value (VSOE), when available; (2) third-party evidence of selling price (TPE), if VSOE does not exist; and (3) estimated selling price (ESP), if neither VSOE nor TPE is available.</font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We determine VSOE based on our historical pricing and discounting practices for the specific solution when sold separately and when a substantial majority of the selling prices for these services fall within a narrow range. TPE is determined based on competitor prices for similar deliverables when sold separately. Generally our go-to-market strategy differs from that of our peers, and our offerings contain a significant level of differentiation such that the comparable pricing of services with similar functionality cannot be obtained. If we have not established VSOE or TPE for our enrollment marketing services, we have used ESP in our allocation of arrangement consideration. Additionally, we limit the amount of revenues recognized for delivered elements to the amount that is not contingent on future delivery of services or other future performance obligations.<br clear="none"/> <br clear="none"/></font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Deferred revenue primarily consists of advanced payments from students related to rentals and subscriptions that have not been recognized, and marketing services that have yet to be performed. Deferred revenue is recognized as revenues ratably over the term or when the services are provided and all other revenue recognition criteria have been met.</font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We evaluate whether we are acting as a principal or an agent, and therefore would record the gross sales amount and related costs as revenues or the net amount earned as commissions from the sale of third party products. Our determination is based on our evaluation of certain indicators including whether we are the principal in the transaction, are subject to inventory risk, have latitude in establishing prices and selecting suppliers, none of which is presumptive or determinative. We generally operate as the principal and so in those instances revenues are recorded at the gross sale price. We generally record the net amounts as commissions earned when such amounts are determined using a fixed percentage of the transaction price, we are not subject to inventory risk or responsible for the fulfillment of the textbooks. We operate as an agent in our strategic partnership with Ingram and therefore our revenues include a commission on the total revenues that we earn from Ingram upon their fulfillment of a rental transaction using books for which Ingram has title and risk of loss.</font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We also present our revenues separately for rental, services and sales. Rental revenue includes the rental of print textbooks for which we take title and bear the risk of loss; service revenue includes Chegg Study, Chegg Tutors, our writing tools service, enrollment marketing, brand advertising, eTextbooks, and commissions we earn from Ingram and other e-commerce partners; sale revenue includes just-in-time sale of print textbooks and the sale of other required materials.</font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">C</font></div></div>

Significant estimates, assumptions, and judgments are used for, but not limited to: revenue recognition, recoverability of accounts receivable, determination of the useful lives and salvage value assigned to our textbook library, restructuring charges, share-based compensation expense including estimated forfeitures, accounting for income taxes, useful lives assigned to long-lived assets for depreciation and amortization, impairment of goodwill and long-lived assets, and the valuation of acquired intangible assets. 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’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.</font></div></div>
