Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation and Summary of Significant Accounting Policies
The accompanying interim consolidated financial statements of Netflix, Inc. and its wholly owned subsidiaries (the “Company”) have been prepared in conformity with accounting principles generally accepted in the United States (“U.S.”) and are consistent in all material respects with those applied in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 filed with the Securities and Exchange Commission (the “SEC”) on January 28, 2021. The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. Significant items subject to such estimates and assumptions include the content asset amortization policy and the recognition and measurement of income tax assets and liabilities. The Company bases its estimates on historical experience and on various other assumptions that the Company believes to be reasonable under the circumstances. On a regular basis, the Company evaluates the assumptions, judgments and estimates. Actual results may differ from these estimates.
The interim financial information is unaudited, but reflects all normal recurring adjustments that are, in the opinion of management, necessary to fairly present the information set forth herein. The interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. Interim results are not necessarily indicative of the results for a full year.
There have been no material changes in the Company’s significant accounting policies as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.

Recently adopted accounting pronouncements
In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-12, Simplifying the Accounting for Income Taxes (Topic 740). ASU 2019-12 removes certain exceptions for performing intraperiod tax allocations, recognizing deferred taxes for investments, and calculating income taxes in interim periods. The guidance also simplifies the accounting for franchise taxes, transactions that result in a step-up in the tax basis of goodwill, and the effect of enacted changes in tax laws or rates in interim periods. The Company adopted ASU 2019-12 in the first quarter of 2021 and the adoption had no material impact to the Company’s consolidated financial statements.

Revenue from Contract with Customer [Abstract]  
Revenue Recognition Revenue Recognition
The Company's primary source of revenues is from monthly membership fees. Members are billed in advance of the start of their monthly membership and revenues are recognized ratably over each monthly membership period. Revenues are presented net of the taxes that are collected from members and remitted to governmental authorities. The Company is the principal in all its relationships where partners, including consumer electronics (“CE”) manufacturers, multichannel video programming distributors (“MVPDs”), mobile operators and internet service providers (“ISPs”), provide access to the service as the Company retains control over service delivery to its members. Typically, payments made to the partners, such as for marketing, are expensed. However, if there is no distinct service provided in exchange for the payments made to the partners or if the price that the member pays is established by the partners and there is no standalone price for the Netflix service (for instance, in a bundle), these payments are recognized as a reduction of revenues.
The following tables summarize streaming revenue, paid net membership additions (losses), and paid memberships at end of period by region for the three and six months ended June 30, 2021 and June 30, 2020, respectively:

(1) A paid membership (also referred to as a paid subscription) is defined as a membership that has the right to receive Netflix service following sign-up and a method of payment being provided, and that is not part of a free trial or certain other promotions that may be offered by the Company to new or rejoining members. A membership is canceled and ceases to be reflected in the above metrics as of the effective cancellation date. Voluntary cancellations generally become effective at the end of the prepaid membership period. Involuntary cancellations, as a result of a failed method of payment, become effective immediately. Memberships are assigned to territories based on the geographic location used at time of sign-up as determined by the Company’s internal systems, which utilize industry standard geo-location technology.
Total U.S. revenues, inclusive of DVD revenues not reported in the tables above, were $3.0 billion and $6.0 billion, respectively, for the three and six months ended June 30, 2021, and $2.7 billion and $5.2 billion, respectively, for the three and six months ended June 30, 2020. DVD revenues were $46 million and $96 million, respectively, for the three and six months ended June 30, 2021 and $62 million and $126 million, respectively, for the three and six months ended June 30, 2020.
Deferred revenue consists of membership fees billed that have not been recognized, as well as gift cards and other prepaid memberships that have not been fully redeemed. As of June 30, 2021, total deferred revenue was $1,187 million, the vast majority of which was related to membership fees billed that are expected to be recognized as revenue within the next month. The remaining deferred revenue balance, which is related to gift cards and other prepaid memberships, will be recognized as revenue over the period of service after redemption, which is expected to occur over the next 12 months. The $69 million increase in deferred revenue as compared to the balance of $1,118 million for the year ended December 31, 2020 is a result of the increase in membership fees billed due to increased members and average monthly revenue per paying member.

Earnings Per Share [Abstract]  
Earnings Per Share Earnings Per Share
Basic earnings per share is computed using the weighted-average number of outstanding shares of common stock during the period. Diluted earnings per share is computed using the weighted-average number of outstanding shares of common stock and, when dilutive, potential outstanding shares of common stock during the period. Potential shares of common stock consist of incremental shares issuable upon the assumed exercise of stock options. The computation of earnings per share is as follows:

Leases
The Company has entered into operating leases primarily for real estate. Operating leases are included in "Other non-current assets" on the Company's Consolidated Balance Sheets, and represent the Company’s right to use the underlying asset for the lease term. The Company’s obligations to make lease payments are included in "Accrued expenses and other liabilities" and "Other non-current liabilities" on the Company's Consolidated Balance Sheets. The Company has entered into various short-term operating leases, primarily for marketing billboards, with an initial term of twelve months or less. These leases are not recorded on the Company's Consolidated Balance Sheets. All operating lease expense is recognized on a straight-line basis over the lease term. Because the rate implicit in each lease is not readily determinable, the Company uses its incremental borrowing rate to determine the present value of the lease payments.
Information related to the Company's operating right-of-use assets and related operating lease liabilities were as follows:

Each of the Notes are repayable in whole or in part upon the occurrence of a change of control, at the option of the holders, at a purchase price in cash equal to 101% of the principal plus accrued interest. The Company may redeem the Notes prior to maturity in whole or in part at an amount equal to the principal amount thereof plus accrued and unpaid interest and an applicable premium. The Notes include, among other terms and conditions, limitations on the Company's ability to create, incur or allow certain liens; enter into sale and lease-back transactions; create, assume, incur or guarantee additional indebtedness of certain of the Company's subsidiaries; and consolidate or merge with, or convey, transfer or lease all or substantially all of the Company's and its subsidiaries assets, to another person. As of June 30, 2021 and December 31, 2020, the Company was in compliance with all related covenants.
Revolving Credit Facility
On June 17, 2021, the Company amended its unsecured revolving credit facility ("Revolving Credit Agreement") to, among other things, extend the maturity date from March 29, 2024 to June 17, 2026 and to increase the size of the facility from $750 million to $1 billion. Revolving loans may be borrowed, repaid and reborrowed until June 17, 2026, at which time all amounts borrowed must be repaid. The Company may use the proceeds of future borrowings under the Revolving Credit Agreement for working capital and general corporate purposes. As of June 30, 2021, no amounts have been borrowed under the Revolving Credit Agreement.
The borrowings under the Revolving Credit Agreement bear interest, at the Company’s option, of either (i) a floating rate equal to a base rate (the “Alternate Base Rate”) or (ii) a rate equal to an adjusted London interbank offered rate (the “Adjusted LIBO Rate”), plus a margin of 0.75%. The Alternate Base Rate is defined as the greatest of (A) the rate of interest published by the Wall Street Journal, from time to time, as the prime rate, (B) the federal funds rate, plus 0.500% and (C) the Adjusted LIBO Rate for a one-month interest period, plus 1.00%. The Adjusted LIBO Rate is defined as the London interbank offered rate for deposits in U.S. dollars, for the relevant interest period, adjusted for statutory reserve requirements, but in no event shall the Adjusted LIBO Rate be less than 0.00% per annum. Regulatory authorities that oversee financial markets have announced that after the end of 2021, they would no longer compel banks currently reporting information used to set the Adjusted LIBO Rate to continue to make rate submissions, and that publication of the Adjusted LIBO Rate based upon U.S. Dollars is expected to cease on June 30, 2023. The Revolving Credit Agreement contains customary provisions for the replacement of the Adjusted LIBO Rate with an alternate benchmark rate, including a rate based on the secured overnight financing rate published by the Federal Reserve Bank of New York, as the Adjusted LIBO Rate is phased out in the lending market. The Company does not anticipate that the replacement of the Adjusted LIBO Rate with such alternative benchmark rate, as provided in the Revolving Credit Agreement, will materially impact its liquidity or financial position.
The Company is also obligated to pay a commitment fee on the undrawn amounts of the Revolving Credit Agreement at an annual rate of 0.10%. The Revolving Credit Agreement requires the Company to comply with certain covenants, including covenants that limit or restrict the ability of the Company’s subsidiaries to incur debt and limit or restrict the ability of the Company and its subsidiaries to grant liens and enter into sale and leaseback transactions; and, in the case of the Company or a guarantor, merge, consolidate, liquidate, dissolve or sell, transfer, lease or otherwise dispose of all or substantially all of the assets of the Company and its subsidiaries, taken as a whole. As of June 30, 2021 and December 31, 2020, the Company was in compliance with all related covenants.

As of December 31, 2020, the Company had $19.2 billion of obligations comprised of $4.4 billion included in "Current content liabilities" and $2.6 billion of "Non-current content liabilities" on the Consolidated Balance Sheets and $12.2 billion of obligations that are not reflected on the Consolidated Balance Sheets as they did not yet meet the criteria for asset recognition.

Total content obligations

Content obligations include amounts related to the acquisition, licensing and production of content. Obligations that are in non-U.S. dollar currencies are translated to the U.S. dollar at period end rates. An obligation for the production of content includes non-cancelable commitments under creative talent and employment agreements as well as other production related commitments. An obligation for the acquisition and licensing of content is incurred at the time the Company enters into an agreement to obtain future titles. Once a title becomes available, a content liability is recorded on the Consolidated Balance Sheets. Certain agreements include the obligation to license rights for unknown future titles, the ultimate quantity and/or fees for which are not yet determinable as of the reporting date. Traditional film output deals, or certain TV series license agreements where the number of seasons to be aired is unknown, are examples of such license agreements. The Company does not include any estimated obligation for these future titles beyond the known minimum amount. However, the unknown obligations are expected to be significant.
Legal Proceedings
From time to time, in the normal course of its operations, the Company is subject to litigation matters and claims, including claims relating to employee relations, business practices and patent infringement. Litigation can be expensive and disruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to predict and the Company's view of these matters may change in the future as the litigation and events related thereto unfold. The Company expenses legal fees as incurred. The Company records a provision for contingent losses when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. An unfavorable outcome to any legal matter, if material, could have an adverse effect on the Company's operations or its financial position, liquidity or results of operations.
The Company is involved in litigation matters not listed herein but does not consider the matters to be material either individually or in the aggregate at this time. The Company's view of the matters not listed may change in the future as the litigation and events related thereto unfold.
Indemnification
In the ordinary course of business, the Company has entered into contractual arrangements under which it has agreed to provide indemnification of varying scope and terms to business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of the Company’s breach of such agreements and out of intellectual property infringement claims made by third parties. In these circumstances, payment may be conditional on the other party making a claim pursuant to the procedures specified in the particular contract.
The Company's obligations under these agreements may be limited in terms of time or amount, and in some instances, the Company may have recourse against third parties for certain payments. In addition, the Company has entered into indemnification agreements with its directors and certain of its officers that will require it, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. The terms of such obligations vary.
It is not possible to make a reasonable estimate of the maximum potential amount of future payments under these or similar agreements due to the conditional nature of the Company’s obligations and the unique facts and circumstances involved in each particular agreement. No amount has been accrued in the accompanying consolidated financial statements with respect to these indemnification obligations.

Stock Option Plan
In June 2020, the Company's stockholders approved the 2020 Stock Plan, which was adopted by the Company’s Board of Directors in March 2020 subject to stockholder approval. The 2020 Stock Plan is the successor to the 2011 Stock Plan and provides for the grant of incentive stock options to employees and for the grant of non-statutory stock options, stock appreciation rights, restricted stock and restricted stock units to employees, directors and consultants.

The aggregate intrinsic value of the Company's outstanding stock options as of June 30, 2021 was $6,388 million and represents the total pretax intrinsic value (the difference between the Company’s closing stock price on the last trading day of the second quarter of 2021 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on the last trading day of the second quarter of 2021. This amount changes based on the fair market value of the Company’s common stock. The weighted-average remaining contractual term of the Company's outstanding stock options as of June 30, 2021 included in the table above was 5.34 years.

The Company considers several factors in determining the suboptimal exercise factor, including the historical and estimated option exercise behavior.
The Company calculates expected volatility based solely on implied volatility. The Company believes that implied volatility of publicly traded options in its common stock is more reflective of market conditions, and given consistently high trade volumes of the options, can reasonably be expected to be a better indicator of expected volatility than historical volatility of its common stock.
In valuing shares issued under the Company’s employee stock option plans, the Company bases the risk-free interest rate on U.S. Treasury zero-coupon issues with terms similar to the contractual term of the options. The Company does not anticipate paying any cash dividends in the foreseeable future and therefore uses an expected dividend yield of zero in the option valuation model. The Company does not use a post-vesting termination rate as options are fully vested upon grant date.
Stock RepurchasesIn March 2021, the Company’s Board of Directors authorized the repurchase of up to $5 billion of its common stock, with no expiration date. Stock repurchases may be effected through open market repurchases in compliance with Rule 10b-18 under the Exchange Act, including through the use of trading plans intended to qualify under Rule 10b5-1 under the Exchange Act, privately-negotiated transactions, accelerated stock repurchase plans, block purchases, or other similar purchase techniques and in such amounts as management deems appropriate. The Company is not obligated to repurchase any specific number of shares, and the timing and actual number of shares repurchased will depend on a variety of factors, including the Company’s stock price, general economic, business and market conditions, and alternative investment opportunities. The Company may discontinue any repurchases of its common stock at any time without prior notice. During the three and six months ended June 30, 2021, the Company repurchased 1,001,565 shares for an aggregate amount of $500 million. As of June 30, 2021, $4.5 billion remain available for repurchases. Shares repurchased by the Company are accounted for when the transaction is settled. As of June 30, 2021, there were no unsettled share repurchases. Direct costs incurred to acquire the shares are included in the total cost of the shares.

Effective tax rate15 %30 %16 %22 %
The effective tax rates for the three and six months ended June 30, 2021 differed from the Federal statutory rate primarily due to the impact of international provisions of the Tax Cuts and Jobs Act and recognition of excess tax benefits of stock-based compensation. The effective tax rates for the three and six months ended June 30, 2020 differed from the Federal statutory rate primarily due to the establishment of a valuation allowance on the California Research and Development (“R&D”) credit that was partially offset by recognition of excess tax benefits of stock-based compensation.
The decrease in effective tax rates for the three and six months ended June 30, 2021, as compared to the same period in 2020 was primarily due to the establishment of a valuation allowance on the California R&D credit in the quarter ended June 30, 2020, partially offset by markedly reduced excess tax benefits related to stock-based compensation as of June 30, 2021. For the three and six months ended June 30, 2021, the Company recognized a discrete tax benefit related to the excess tax benefits from stock-based compensation of $19 million and $66 million, respectively, compared to the three and six months ended June 30, 2020 of $92 million and $157 million, respectively.
Gross unrecognized tax benefits were $177 million and $140 million as of June 30, 2021 and December 31, 2020, respectively. The gross unrecognized tax benefits, if recognized by the Company, will result in a reduction of approximately $109 million to the provision for income taxes thereby favorably impacting the Company’s effective tax rate. As of June 30, 2021, gross unrecognized tax benefits of $38 million were classified as “Other non-current liabilities” and $139 million as a reduction to deferred tax assets which was classified as "Other non-current assets" in the Consolidated Balance Sheets. The Company includes interest and penalties related to unrecognized tax benefits within the "Provision for income taxes" on the Consolidated Statements of Operations and “Other non-current liabilities” in the Consolidated Balance Sheets. Interest and penalties included in the Company’s “Provision for income taxes” were not material in any of the periods presented.
Deferred tax assets of $378 million and $589 million were classified as “Other non-current assets” on the Consolidated Balance Sheets as of June 30, 2021 and December 31, 2020, respectively. In evaluating its ability to realize the net deferred tax assets, the Company considered all available positive and negative evidence, including its past operating results and the forecast of future market growth, forecasted earnings, future taxable income, and prudent and feasible tax planning strategies. The Company has a valuation allowance of $326 million and $250 million as of June 30, 2021 and December 31, 2020, respectively. The valuation allowance is related to the California R&D credits and certain foreign tax attributes that the Company does not expect to realize.
The Company files U.S. Federal, state and foreign tax returns. The Company is currently under examination by the IRS for 2016 through 2018 and is subject to examination for 2019. The 2015 through 2019 state tax returns are subject to examination by various state tax authorities. The Company has no significant foreign jurisdiction audits underway. The years 2015 through 2020 generally remain subject to examination by foreign tax authorities.
Given the potential outcome of the current examinations, as well as the impact of the current examinations on the potential expiration of the statute of limitations, it is reasonably possible that the balance of unrecognized tax benefits could significantly change within the next twelve months. At this time, an estimate of the range of reasonably possible adjustments to the balance of unrecognized tax benefits cannot be made.

Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Use of Estimates The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. Significant items subject to such estimates and assumptions include the content asset amortization policy and the recognition and measurement of income tax assets and liabilities. The Company bases its estimates on historical experience and on various other assumptions that the Company believes to be reasonable under the circumstances. On a regular basis, the Company evaluates the assumptions, judgments and estimates. Actual results may differ from these estimates.
Recently adopted accounting pronouncements
Recently adopted accounting pronouncements
In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-12, Simplifying the Accounting for Income Taxes (Topic 740). ASU 2019-12 removes certain exceptions for performing intraperiod tax allocations, recognizing deferred taxes for investments, and calculating income taxes in interim periods. The guidance also simplifies the accounting for franchise taxes, transactions that result in a step-up in the tax basis of goodwill, and the effect of enacted changes in tax laws or rates in interim periods. The Company adopted ASU 2019-12 in the first quarter of 2021 and the adoption had no material impact to the Company’s consolidated financial statements.

(1) A paid membership (also referred to as a paid subscription) is defined as a membership that has the right to receive Netflix service following sign-up and a method of payment being provided, and that is not part of a free trial or certain other promotions that may be offered by the Company to new or rejoining members. A membership is canceled and ceases to be reflected in the above metrics as of the effective cancellation date. Voluntary cancellations generally become effective at the end of the prepaid membership period. Involuntary cancellations, as a result of a failed method of payment, become effective immediately. Memberships are assigned to territories based on the geographic location used at time of sign-up as determined by the Company’s internal systems, which utilize industry standard geo-location technology.
