Accounting Policies [Abstract]  
Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation and Summary of Significant Accounting Policies
Basis of Presentation and Principles of Consolidation
In September 2019, we adopted a 52/53 week fiscal year consisting of four 13-week quarters ending on the first Sunday after January 30, which for fiscal 2021 was January 31, 2021 and for fiscal 2022 will be February 6, 2022. The second quarter of fiscal 2021 and 2022 ended on August 2, 2020 and August 1, 2021. Unless otherwise stated, all dates refer to our fiscal year and fiscal periods.
The condensed consolidated financial statements include the accounts of the Company and our wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
There were no material changes in the second quarter of fiscal 2022 to our significant accounting policies as described in our Annual Report on Form 10-K for fiscal 2021.
Unaudited Interim Consolidated Financial Information
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP) and applicable rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for fiscal 2021.
In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year 2022 or any future period.
Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and accompanying notes. Actual results could differ from these estimates and assumptions due to risks and uncertainties, including uncertainty in the current economic environment from the ongoing COVID-19 pandemic. Such estimates include, but are not limited to, the determination of standalone selling price for revenue arrangements with multiple performance obligations, useful lives of intangible assets and property and equipment, the period of benefit for deferred contract costs for commissions, stock-based compensation, provision for income taxes including related reserves, and the fair value of equity assumed, intangible and tangible assets acquired and liabilities assumed for business combinations. Management bases its estimates on historical experience and on various other assumptions which management believes to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.
Restricted Cash
Restricted cash is comprised of cash collateral for letters of credit related to our leases and for a vendor credit card program. At the end of fiscal 2021 and the second quarter of fiscal 2022, we had restricted cash of $10.5 million.
Recent Accounting Pronouncements Not Yet Adopted
In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by the reference rate reform if certain criteria are met. The amendments apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848) which refines the scope of Topic 848 and clarifies some of its guidance. The amendments are effective for all entities as of March 12, 2020 through December 31, 2022. We are currently evaluating the impact of this standard on our condensed consolidated financial statements.
In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity's Own Equity, which simplifies the accounting for certain convertible instruments, amends guidance on derivative scope exceptions for contracts in an entity's own equity, and modifies the guidance on diluted earnings per share calculations as a result of these changes. The standard will be effective for us beginning February 7, 2022 and can be applied on either a fully retrospective or modified retrospective basis. We are currently evaluating the impact of this standard on our condensed consolidated financial statements.

Fair Value Measurements
We define fair value as the exchange price that would be received from sale of an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We measure our financial assets and liabilities at fair value at each reporting period using a fair value hierarchy which requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
Three levels of inputs may be used to measure fair value:
•Level 1 - Observable inputs are unadjusted quoted prices in active markets for identical assets or liabilities;
•Level 2 - Observable inputs are quoted prices for similar assets and liabilities in active markets or inputs other than quoted prices that are observable for the assets or liabilities, either directly or indirectly through market corroboration, for substantially the full term of the financial instruments; and
•Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. These inputs are based on our own assumptions used to measure assets and liabilities at fair value and require significant management judgment or estimation.
Cash Equivalents, Marketable Securities and Restricted Cash
We measure our cash equivalents, marketable securities, and restricted cash at fair value on a recurring basis. We classify our cash equivalents, marketable securities and restricted cash within Level 1 or Level 2 because they are valued using either quoted market prices or inputs other than quoted prices which are directly or indirectly observable in the market, including readily-available pricing sources for the identical underlying security which may not be actively traded. Our fixed income available-for-sale securities consist of high quality, investment grade securities from diverse issuers. The valuation techniques used to measure the fair value of our marketable securities were derived from non-binding market consensus prices that are corroborated by observable market data or quoted market prices for similar instruments. The following tables summarize our cash equivalents, marketable securities and restricted cash by significant investment categories and their classification within the valuation hierarchy at the end of fiscal 2021 and the second quarter of fiscal 2022 (in thousands):

Unrealized losses on our debt securities have not been recorded into income because we do not intend to sell nor is it more likely than not that we will be required to sell these investments prior to recovery of their amortized cost basis. The decline in fair value of our debt securities is largely due to changes in credit spreads as a result of market conditions. The credit ratings associated with our debt securities are mostly unchanged, are highly rated and the issuers continue to make timely principal and interest payments. As a result, there were no credit losses in the second quarter and the first two quarters of fiscal 2021 and 2022.

Fair Value Measurements of Other Financial Instruments
We measure the fair value of our convertible senior notes (the Notes) on a quarterly basis for disclosure purposes. We consider the fair value of the Notes at the end of the second quarter of fiscal 2022 to be a Level 2 measurement due to its limited trading activity. Refer to Note 6 for the carrying amount and estimated fair value of our Notes at the end of the second quarter of fiscal 2022.

Remaining Performance Obligations
Total remaining performance obligations (RPO) which is contracted but not recognized revenue was $1,196.0 million at the end of the second quarter of fiscal 2022. RPO consists of both deferred revenue and non-cancelable amounts that are expected to be invoiced and recognized as revenue in future periods. Product orders are generally cancelable until delivery has occurred, and as such unfulfilled product orders are excluded from RPO. Of the $1,196.0 million contracted but not recognized revenue at the end of the second quarter of fiscal 2022, we expect to recognize approximately 45% over the next 12 months, and the remainder thereafter.

Debt Disclosure [Abstract]  
Debt Debt
Convertible Senior Notes
In April 2018, we issued $575.0 million in principal amount of 0.125% convertible senior notes due 2023, in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act and received proceeds of $562.1 million, after deducting the underwriters’ discounts and commissions. The Notes are governed by an indenture (the Indenture) between us, as the issuer, and U.S. Bank National Association, as trustee. The Notes are our senior unsecured obligations. The Indenture does not contain any financial covenants or restrictions on the payments of dividends, the incurrence of indebtedness, or the issuance or repurchase of securities by us or any of our subsidiaries. The Notes mature on April 15, 2023 unless repurchased or redeemed by us or converted in accordance with their terms prior to the maturity date. Interest is payable semi-annually in arrears on April 15 and October 15 of each year.
The Notes are convertible for up to 21,884,155 shares of our common stock at an initial conversion rate of approximately 38.0594 shares of common stock per $1,000 principal amount, which is equal to an initial conversion price of approximately $26.27 per share of common stock, subject to adjustment. Holders of the Notes may surrender their Notes for conversion at their option at any time prior to the close of business on the business day immediately preceding October 15, 2022, only under the following circumstances:
•during any fiscal quarter commencing after the fiscal quarter ended on July 31, 2018 (and only during such fiscal quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price for the Notes on each applicable trading day;

•during the five business day period after any five consecutive trading day period (the measurement period), in which the trading price per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the Notes on each such trading day;

•if we call any or all of the Notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or

•upon the occurrence of specified corporate events.
On or after October 15, 2022 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their Notes at any time regardless of the foregoing circumstances. Upon conversion, holders will receive cash, shares of our common stock, or a combination of cash and shares of our common stock, at our election. We intend to settle the principal of the Notes in cash.
The conversion price will be subject to adjustment in some events. Following certain corporate events that occur prior to the maturity date or following our issuance of a notice of redemption, we will increase the conversion rate for a holder who elects to convert its Notes in connection with such corporate event or during the related redemption period in certain circumstances. Additionally, upon the occurrence of a corporate event that constitutes a “fundamental change” per the Indenture, holders of the Notes may require us to repurchase for cash all or a portion of the Notes at a purchase price equal to 100% of the principal amount of the Notes plus accrued and unpaid contingent interest.
Subsequent to April 19, 2021, we may redeem for cash all or any portion of the Notes, at our option, if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending not more than two trading days immediately preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. No sinking fund is provided for the Notes.
Upon the issuance of the Notes, we recorded total debt issuance costs of $12.9 million, of which $9.8 million was allocated to the Notes and $3.1 million was allocated to additional paid-in capital.
The Notes consisted of the following (in thousands):

The total estimated fair value of the Notes at the end of the second quarter of fiscal 2022 was $607.3 million. The fair value was determined based on the closing trading price per $100 of the Notes as of the last day of trading for the period. The fair value of the Notes is primarily affected by the trading price of our common stock and market interest rates. Based on the closing price of our common stock of $19.52 on the last day of the second quarter of fiscal 2022, the if-converted value of the Notes of $427.2 million was less than its principal amount. At the end of the second quarter of fiscal 2022, the remaining term of the Notes is approximately 20 months.

In connection with the offering of the Notes, we paid $64.6 million to enter into capped call transactions with certain of the underwriters and their affiliates (the Capped Calls), whereby we have the option to purchase a total of 21,884,155 shares of our common stock upon any conversion of Notes and/or offset any cash payments we are required to make in excess of the principal amount of the Notes, as the case may be, with such reduction or offset subject to a cap initially equal to $39.66 per share (which represents a premium of 100% over the last reported sales price of our common stock on April 4, 2018), subject to certain adjustments (the Cap Price). The cost of the Capped Calls was accounted for as a reduction to additional paid-in capital on the condensed consolidated balance sheet. The Capped Calls are intended to reduce or offset potential dilution of our common stock upon any conversion of the Notes, subject to a cap based on the Cap Price.

Impact on Earnings Per Share
The Notes will not impact our diluted earnings per share until the average market price of our common stock exceeds the conversion price of $26.27 per share, as we intend to settle the principal amount of the Notes in cash upon conversion. We are required under the treasury stock method to compute the potentially dilutive shares of common stock related to the Notes for periods we report net income. However, upon conversion, there will be no economic dilution from the Notes until the average market price of our common stock exceeds the Cap Price of $39.66 per share, as exercise of the Capped Calls offsets any dilution from the Notes from the conversion price up to the Cap Price. Capped Calls are excluded from the calculation of diluted earnings per share, as they would be anti-dilutive under the treasury stock method.
Revolving Credit Facility
On August 24, 2020, we entered into a Credit Agreement with a consortium of financial institutions and lenders that provides for a five-year, senior secured revolving credit facility of $300.0 million (Credit Facility). Proceeds from the Credit Facility may be used for general corporate purposes and working capital. The Credit Facility expires, absent default or early termination by us, on the earlier of (i) August 24, 2025 or (ii) 91 days prior to the stated maturity of the Notes unless, on such date and each subsequent day until the Notes are paid in full, the sum of our cash, cash equivalents and marketable securities and the aggregate unused commitments then available to us exceed $625.0 million.
The annual interest rates applicable to loans under the Credit Facility are, at our option, equal to either a base rate plus a margin ranging from 0.50% to 1.25% or LIBOR (based on one, three or six-month interest periods), subject to a floor of 0%, plus a margin ranging from 1.50% to 2.25%. Interest on revolving loans is payable quarterly in arrears with respect to loans based on the base rate and at the end of an interest period in the case of loans based on LIBOR (or at each three-month interval if the interest period is longer than three months). We are also required to pay a commitment fee on the unused portion of the commitments ranging from 0.25% to 0.40% per annum, payable quarterly in arrears.
In September 2020, we drew down $250.0 million under the Credit Facility which remained outstanding at the end of the second quarter of fiscal 2022. The outstanding loan bore weighted-average interest at the one-month LIBOR of approximately 1.60% and 1.61% resulting in interest expense of $1.0 million and $2.0 million during the second quarter and first two quarters of fiscal 2022.
Loans under the Credit Facility are collateralized by substantially all of our assets and subject to certain restrictions and two financial ratios measured as of the last day of each fiscal quarter: a Consolidated Leverage Ratio not to exceed 4.5:1 and an Interest Coverage Ratio not to be less than 3:1. We were in compliance with all covenants under the Credit Facility at the end of the second quarter of fiscal 2022.

Letters of Credit
At the end of fiscal 2021 and the second quarter of fiscal 2022, we had outstanding letters of credit in the aggregate amount of $6.7 million in connection with our facility leases. The letters of credit are collateralized by restricted cash and mature on various dates through August 2029.
Legal Matters
From time to time, we have become involved in claims and other legal matters arising in the normal course of business. We investigate these claims as they arise. Although claims are inherently unpredictable, we currently are not aware of any matters that we expect to have a material adverse effect on our business, financial position, results of operations or cash flows. Accordingly, we have not recorded any loss contingency on our condensed consolidated balance sheet at the end of the second quarter of fiscal 2022.
Indemnification
Our arrangements generally include certain provisions for indemnifying customers against liabilities if our products or services infringe a third party’s intellectual property rights. Other guarantees or indemnification arrangements include guarantees of product and service performance and standby letters of credit for lease facilities. It is not possible to determine the maximum potential amount under these indemnification obligations due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. To date, we have not incurred any material costs as a result of such obligations and have not accrued any liabilities related to such obligations in the condensed consolidated financial statements. In addition, we indemnify our officers, directors and certain key employees while they are serving in good faith in their respective capacities. To date, there have been no claims under any indemnification provisions.

During the second quarter and first two quarters of fiscal 2021, we ceased use of certain leased facilities. The unamortized costs of $7.5 million relating to operating lease right-of-use assets and leasehold improvements for these leases were expensed.
During the second quarter and first two quarters of fiscal 2021, we effected workforce realignment plans to streamline our operations and recognized $0.8 million and $6.6 million of restructuring costs related to involuntary termination benefit costs. The restructuring charges are included in restructuring and other expenses in our condensed consolidated statement of operations.
During the first two quarters of fiscal 2021, we incurred incremental costs of $9.8 million directly related to the COVID-19 pandemic. These costs primarily included the write-off of marketing commitments no longer deemed to have value for the remainder of fiscal 2021, estimated non-recoverable costs for internal events that could not be held, and hazard related premiums to support manufacturing operations. Of these costs, $8.9 million is included in restructuring and other expenses and $0.9 million is included in cost of revenue in our condensed consolidated statements of operations for the first two quarters of fiscal 2021.

Equity [Abstract]  
Stockholders' Equity Stockholders’ Equity
Preferred Stock
We have 20,000,000 authorized shares of undesignated preferred stock, the rights, preferences and privileges of which may be designated from time to time by our board of directors. At the end of the second quarter of fiscal 2022, there were no shares of preferred stock issued or outstanding.
Class A and Class B Common Stock
We have two classes of authorized common stock, Class A common stock, which we refer to as our "common stock", and Class B common stock. At the end of the second quarter of fiscal 2022, we had 2,000,000,000 authorized shares of Class A common stock and 250,000,000 authorized shares of Class B common stock, with each class having a par value of $0.0001 per share. At the end of the second quarter of fiscal 2022, 284,733,647 shares of Class A common stock were issued and outstanding.
Share Repurchase Program
In February 2021, our board of directors authorized the repurchase of up to an additional $200.0 million of our common stock. During the second quarter of fiscal 2022, we repurchased and retired 2,312,697 shares of common stock at an average purchase price of $19.17 per share for an aggregate repurchase price of $44.3 million. During the first two quarters of fiscal 2022, we repurchased and retired 3,695,766 shares of common stock at an average purchase price of $20.11 per share for an aggregate repurchase price of $74.3 million. At the end of the second quarter of fiscal 2022, $125.7 million remained available for future share repurchases under our current repurchase authorization.

Equity Incentive Plans Equity Incentive Plans
Equity Incentive Plans
We maintain two equity incentive plans: the 2009 Equity Incentive Plan (the 2009 Plan) and the 2015 Equity Incentive Plan (the 2015 Plan). The 2015 Plan serves as the successor to our 2009 Plan and provides for grants of incentive stock options to our employees and non-statutory stock options, stock appreciation rights, restricted stock, restricted stock units (RSUs), performance stock awards, performance cash awards, and other forms of stock awards to our employees, directors and consultants. Our equity awards generally vest over a two to four year period and expire no later than ten years from the date of grant.
We net-share settle equity awards held by certain employees by withholding shares upon vesting to satisfy tax withholding obligations. The shares withheld to satisfy employee tax withholding obligations are returned to our 2015 Plan and will be available for future issuance. Payments for employees’ tax obligations to the tax authorities are recognized as a reduction to additional paid-in capital and reflected as a financing activity in our condensed consolidated statements of cash flows.
2015 Amended and Restated Employee Stock Purchase Plan
Under our Amended and Restated 2015 Employee Stock Purchase Plan (2015 ESPP), our board of directors (or a committee thereof) has the authority to establish the length and terms of the offering periods and purchase periods and the purchase price of the shares of common stock which may be purchased under the plan. The current offering terms allow eligible employees to purchase shares of our common stock at a discount through payroll deductions of up to 30% of their eligible compensation, subject to a cap of 3,000 shares on any purchase date, a dollar cap of $7,500 per purchase period, or $25,000 in any calendar year (as determined under applicable tax rules). The current terms also allow for a 24-month offering period beginning March 16th and September 16th of each year, with each offering period consisting of four 6-month purchase periods, subject to a reset provision. Further, currently, on each purchase date, eligible employees may purchase our common stock at a price per share equal to 85% of the lesser of the fair market value of our common stock (1) on the first trading day of the applicable offering period or (2) the purchase date.
Under the reset provision currently authorized, if the closing stock price on the offering date of a new offering falls below the closing stock price on the offering date of an ongoing offering, the ongoing offering would terminate immediately following the purchase of ESPP shares on the purchase date immediately preceding the new offering and participants in the terminated ongoing offering would automatically be enrolled in the new offering (ESPP reset), resulting in a modification charge to be recognized over the new offering period. During the first quarter of fiscal 2021, there was an ESPP reset that resulted in a modification charge of $23.8 million, which is being recognized over an offering period ending March 15, 2022. There was no ESPP reset during the first two quarters of fiscal 2022.
Stock-based compensation expense related to our 2015 ESPP was $6.4 million and $8.8 million during the second quarter of fiscal 2021 and 2022, and $12.0 million and $16.4 million during the first two quarters of fiscal 2021 and 2022. At the end of the second quarter of fiscal 2022, total unrecognized stock-based compensation cost related to our 2015 ESPP was $25.2 million, which is expected to be recognized over a weighted-average period of 0.8 years.

Earnings Per Share [Abstract]  
Net Loss per Share Attributable to Common Stockholders Net Loss per Share Attributable to Common StockholdersBasic and diluted net loss per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, less shares subject to repurchase. Diluted net loss per share attributable to common stockholders is computed by giving effect to all potentially dilutive common stock equivalents, including our outstanding stock options, common stock related to unvested RSUs, unvested restricted stock, our Notes to the extent dilutive, and common stock issuable pursuant to the ESPP. These potentially dilutive common stock equivalents have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is anti-dilutive.
The following table sets forth the computation of basic and diluted net loss per share attributable to common stockholders (in thousands, except per share data):

Income Taxes Income Taxes
Our provision for income tax primarily reflects taxes on international operations and state income taxes. The difference between the income tax provision that would be derived by applying the statutory rate to our loss before income taxes and the income tax provision recorded was primarily attributable to changes in our valuation allowance, U.S. taxes on foreign income and research and development credits.
At the end of the second quarter of fiscal 2022, there were no material changes to either the nature or the amounts of the uncertain tax positions previously determined for fiscal 2021.

Basis of Presentation and Principles of Consolidation
In September 2019, we adopted a 52/53 week fiscal year consisting of four 13-week quarters ending on the first Sunday after January 30, which for fiscal 2021 was January 31, 2021 and for fiscal 2022 will be February 6, 2022. The second quarter of fiscal 2021 and 2022 ended on August 2, 2020 and August 1, 2021. Unless otherwise stated, all dates refer to our fiscal year and fiscal periods.
The condensed consolidated financial statements include the accounts of the Company and our wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
There were no material changes in the second quarter of fiscal 2022 to our significant accounting policies as described in our Annual Report on Form 10-K for fiscal 2021.
Unaudited Interim Consolidated Financial Information
Unaudited Interim Consolidated Financial Information
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP) and applicable rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for fiscal 2021.
In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year 2022 or any future period.
Use of Estimates
Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and accompanying notes. Actual results could differ from these estimates and assumptions due to risks and uncertainties, including uncertainty in the current economic environment from the ongoing COVID-19 pandemic. Such estimates include, but are not limited to, the determination of standalone selling price for revenue arrangements with multiple performance obligations, useful lives of intangible assets and property and equipment, the period of benefit for deferred contract costs for commissions, stock-based compensation, provision for income taxes including related reserves, and the fair value of equity assumed, intangible and tangible assets acquired and liabilities assumed for business combinations. Management bases its estimates on historical experience and on various other assumptions which management believes to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.

Recent Accounting Pronouncements Not Yet Adopted
In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by the reference rate reform if certain criteria are met. The amendments apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848) which refines the scope of Topic 848 and clarifies some of its guidance. The amendments are effective for all entities as of March 12, 2020 through December 31, 2022. We are currently evaluating the impact of this standard on our condensed consolidated financial statements.
In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity's Own Equity, which simplifies the accounting for certain convertible instruments, amends guidance on derivative scope exceptions for contracts in an entity's own equity, and modifies the guidance on diluted earnings per share calculations as a result of these changes. The standard will be effective for us beginning February 7, 2022 and can be applied on either a fully retrospective or modified retrospective basis. We are currently evaluating the impact of this standard on our condensed consolidated financial statements.
Fair Value Measurements
Fair Value Measurements
We define fair value as the exchange price that would be received from sale of an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We measure our financial assets and liabilities at fair value at each reporting period using a fair value hierarchy which requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
Three levels of inputs may be used to measure fair value:
•Level 1 - Observable inputs are unadjusted quoted prices in active markets for identical assets or liabilities;
•Level 2 - Observable inputs are quoted prices for similar assets and liabilities in active markets or inputs other than quoted prices that are observable for the assets or liabilities, either directly or indirectly through market corroboration, for substantially the full term of the financial instruments; and
•Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. These inputs are based on our own assumptions used to measure assets and liabilities at fair value and require significant management judgment or estimation.
