SUMMARY OF RISK FACTORS

Below is a summary of the principal factors that could materially harm our business, operating results and/or financial condition, impair our future prospects or cause the price of our Class A common stock to decline. This summary does not address all of the risks that we face. Additional discussion of the risks summarized in this risk factor summary, and other risks that we face, can be found below under the heading “Risk Factors” and should be carefully considered, together with other information in this Form 10-Q and our other filings with the Securities and Exchange Commission ("SEC") before making an investment decision regarding our Class A common stock.

•Our business depends on our ability to retain and upgrade paying users, and any decline in renewals or upgrades could adversely affect our future results of operations.

•Our future growth could be harmed if we fail to attract new users or convert registered users to paying users.

•Our revenue growth rate has declined in recent periods and may continue to slow in the future.

•We have a limited history of operating with a Virtual First workforce and the long-term impact on our financial results and business operations is uncertain.

•We operate in competitive markets, and we must continue to compete effectively.

•Our business could be damaged, and we could be subject to liability if there is any unauthorized access to our data or our users' content, including through privacy and data security breaches.

•Our business could be harmed by any significant disruption of service on our platform or loss of content.

•The full extent of the impacts of the COVID-19 pandemic on our business is currently unknown, but it may adversely affect our financial results as well as our business operations.

•We generate revenue from sales of subscriptions to our platform, and any decline in demand for our platform or for content collaboration solutions in general could negatively impact our business.

•Our business depends upon the interoperability of our platform across devices, operating systems, and third-party applications that we do not control.

•Failure to respond to rapid technological changes, extend our platform, or develop new features or products may harm our ability to compete effectively, which would adversely affect our business.

•We may not successfully manage our growth or plan for future growth.

•We depend on our key personnel and other highly qualified personnel, and if we fail to attract, integrate, and retain our personnel, and maintain our unique corporate culture, our business could be harmed.

•We have a history of net losses, we may increase expenses in the future, and we may not be able to achieve or to maintain profitability.

•Our lack of a significant outbound sales force may limit the potential growth of our business.

•Servicing our 2026 Notes and 2028 Notes may require a significant amount of cash, and we may not have sufficient cash flow or the ability to raise the funds necessary to satisfy our obligations under the 2026 Notes or 2028 Notes.

(Amounts in tables are in millions except per share data, or as otherwise noted)


Note 1. Description of the Business and Summary of Significant Accounting Policies

Business
Dropbox, Inc. (the “Company” or “Dropbox”) helps keep life organized and work moving. Dropbox was incorporated in May 2007 as Evenflow, Inc., a Delaware corporation, and changed its name to Dropbox, Inc. in October 2009. The Company is headquartered in San Francisco, California.

Basis of presentation and consolidation
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the United States of America generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting. The accompanying unaudited condensed consolidated financial statements include the accounts of Dropbox and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

The condensed consolidated balance sheet as of December 31, 2020 included herein was derived from the audited financial statements as of that date. The unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the balance sheets, statements of operations, statements of comprehensive income, statements of stockholders' (deficit) equity and the statements of cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year ended December 31, 2021 or any future period.

The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2020, included in the Company's Annual Report on Form 10-K on file with the SEC ("Annual Report").

Use of estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the Company’s condensed consolidated financial statements and accompanying notes. These estimates are based on information available as of the date of the condensed consolidated financial statements. Management evaluates these estimates and assumptions on a regular basis. Actual results may differ materially from these estimates.

The Company’s most significant estimates and judgments involves the valuation of acquired intangible assets and goodwill from business combinations as well as the valuation of right-of-use and other lease related assets.

Financial information about segments and geographic areas
The Company manages its operations and allocates resources as a single operating segment. Further, the Company manages, monitors, and reports its financials as a single reporting segment. The Company’s chief operating decision-maker is its Chief Executive Officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance, and allocating resources. See Note 15 "Geographic Areas" for information regarding the Company’s long-lived assets and revenue by geography.

Foreign currency transactions
The assets and liabilities of the Company’s foreign subsidiaries are translated from their respective functional currencies into U.S. dollars at the exchange rates in effect at the balance sheet date. Revenue and expense amounts are translated at the average exchange rate for the period. Foreign currency translation gains and losses are recorded in other comprehensive income.

DROPBOX, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Amounts in tables are in millions except per share data, or as otherwise noted)

Gains and losses realized from foreign currency transactions (those transactions denominated in currencies other than the foreign subsidiaries’ functional currency) are included in other income, net. Monetary assets and liabilities are remeasured using foreign currency exchange rates at the end of the period, and non-monetary assets are remeasured based on historical exchange rates. The Company recorded net foreign currency transaction gains of $0.2 million during the three months ended March 31, 2021, and net foreign currency transaction losses of $1.2 million during the three months ended March 31, 2020.

Revenue recognition
The Company derives its revenue from subscription fees from customers for access to its platform. The Company’s policy is to exclude sales and other indirect taxes when measuring the transaction price of its subscription agreements. The Company accounts for revenue contracts with customers through the following steps:
•Identification of the contract, or contracts, with a customer
•Identification of the performance obligations in the contract
•Determination of the transaction price
•Allocation of the transaction price to the performance obligations in the contract
•Recognition of revenue when, or as, the Company satisfies a performance obligation

The Company’s subscription agreements generally have monthly or annual contractual terms and a small percentage have multi-year contractual terms. Revenue is recognized ratably over the related contractual term beginning on the date that the platform is made available to a customer. Access to the platform represents a series of distinct services as the Company continually provides access to, and fulfills its obligation to the end customer over the subscription term. The series of distinct services represents a single performance obligation that is satisfied over time. The Company recognizes revenue ratably because the customer receives and consumes the benefits of the platform throughout the contract period. The Company’s contracts are generally non-cancelable.

The Company bills in advance for monthly contracts and typically bills annually in advance for contracts with terms of one year or longer. The Company also recognizes an immaterial amount of contract assets, or unbilled receivables, primarily relating to consideration for services completed but not billed at the reporting date. Unbilled receivables are classified as receivables when the Company has the right to invoice the customer.

The Company records contract liabilities when cash payments are received or due in advance of performance to deferred revenue. Deferred revenue primarily relates to the advance consideration received from the customer.

The price of subscriptions is generally fixed at contract inception and therefore, the Company’s contracts do not contain a significant amount of variable consideration. As a result, the amount of revenue recognized in the periods presented from performance obligations satisfied (or partially satisfied) in previous periods was not material.

The Company recognized $283.8 million and $257.5 million of revenue during the three months ended March 31, 2021 and 2020, respectively, that was included in the deferred revenue balances at the beginning of their respective periods.

As of March 31, 2021, future estimated revenue related to performance obligations that were unsatisfied or partially unsatisfied was $697.6 million. The substantial majority of the unsatisfied performance obligations will be satisfied over the next twelve months.

Stock-based compensation
The Company has primarily granted restricted stock units ("RSUs") to its employees and members of the Board of Directors under the 2008 Equity Incentive Plan (“2008 Plan”), the 2017 Equity Incentive Plan (“2017 Plan”), and the 2018 Equity Incentive Plan ("2018 Plan" and together with the 2008 Plan and 2017 Plan, the "Dropbox Equity Incentive Plans"). The RSUs granted by the Company under the Dropbox Equity Incentive Plans have a service-based vesting condition over a four-year period. These awards typically have a cliff vesting period of one year and continue to vest quarterly thereafter. The Company recognizes compensation expense associated with RSUs ratably on a straight-line basis over the requisite service period and accounts for forfeitures in the period in which they occur. As of March 31, 2021, the Company had RSUs and restricted stock awards ("RSAs") granted to certain executives outstanding under the Dropbox Equity Incentive Plans.

DROPBOX, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Amounts in tables are in millions except per share data, or as otherwise noted)


The fair values of the common stock underlying the RSUs granted in periods prior to the date of the Company's IPO were determined by the Board of Directors, with input from management and contemporaneous third-party valuations, which were performed at least quarterly. For valuations after the Company's IPO, the Board of Directors determines the fair value of each share of underlying common stock based on the closing price of the Company's Class A common stock as reported on the Nasdaq Global Select Market on the date of the grant.

In connection with the acquisition of DocSend, Inc. ("DocSend"), the Company assumed unvested stock options and an immaterial number of unvested RSUs that had been granted under DocSend's 2013 Stock Plan and DocSend's 2015 Stock Option and Grant Plan. The fair value of the DocSend options assumed were based upon the Black-Scholes option-pricing model. See Note 12 "Stockholders' (Deficit) Equity" for further information.

In December 2017, the Board of Directors approved a grant to the Company’s co-founders of RSAs with respect to 14.7 million shares of Class A common stock in the aggregate (collectively, the “Co-Founder Grants”), of which 10.3 million RSAs were granted to Mr. Houston, the Company’s co-founder and Chief Executive Officer, and 4.4 million RSAs were granted to Mr. Ferdowsi, the Company's co-founder and a former director. These Co-Founder Grants have service-based, market-based, and performance-based vesting conditions. The Company estimated the grant date fair value of the Co-Founder Grants using a model based on multiple stock price paths developed through the use of a Monte Carlo simulation that incorporates into the valuation the possibility that the Stock Price Targets may not be satisfied. Effective March 19, 2020, Mr. Ferdowsi resigned as a member of the Board of Directors and as an officer of the Company. As of the date of Mr. Ferdowsi's resignation, none of the Stock Price Targets had been met, resulting in the forfeiture of his 4.4 million RSAs. See Note 12 "Stockholders' (Deficit) Equity" for further information.

Cost of revenue
Cost of revenue consists primarily of expenses associated with the storage, delivery, and distribution of the Company’s platform for both paying users and free users, also known as Basic users. These costs, which are referred to as infrastructure costs, include depreciation of servers located in co-location facilities that the Company leases and operates, rent and facilities expense for those datacenters, network and bandwidth costs, support and maintenance costs for infrastructure equipment, and payments to third-party datacenter service providers. Cost of revenue also includes costs, such as salaries, bonuses, benefits, travel-related expenses, and stock-based compensation, which are referred to as employee-related costs, for employees whose primary responsibilities relate to supporting the Company’s infrastructure and delivering user support. Other non-employee costs included in cost of revenue include credit card fees related to processing customer transactions and allocated overhead, such as facilities, including rent, utilities, depreciation on leasehold improvements and other equipment shared by all departments, and shared information technology costs. In addition, cost of revenue includes amortization of developed technologies, professional fees related to user support initiatives, and property taxes related to the datacenters.

Cash and cash equivalents
Cash consists primarily of cash on deposit with banks and includes amounts in transit from payment processors for credit and debit card transactions, which typically settle within five business days. Cash equivalents include highly liquid investments purchased with an original maturity date of 90 days or less from the date of purchase.
The Company monitors its credit risk by considering factors such as historical experience, credit ratings, current economic conditions, and reasonable and supportable forecasts.

Short-term investments
The Company’s short-term investments are primarily comprised of corporate notes and obligations, U.S. Treasury securities, certificates of deposit, asset-backed securities, commercial paper, U.S. agency obligations, foreign government securities, supranational securities and municipal securities. The Company determines the appropriate classification of its short-term investments at the time of purchase and reevaluates such designation at each balance sheet date. The Company has classified and accounted for its short-term investments as available-for-sale securities as the Company may sell these securities at any time for use in its current operations or for other purposes, even prior to maturity. As a result, the Company classifies its short-term investments, including securities with stated maturities beyond twelve months, within current assets in the condensed consolidated balance sheets.

13
DROPBOX, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Amounts in tables are in millions except per share data, or as otherwise noted)

The Company's short-term investments are recorded at fair value each reporting period. Unrealized gains and losses on these short-term investments are reported as a separate component of accumulated other comprehensive income in the condensed consolidated balance sheets until realized. Unrealized gains and losses for any short-term investments that management intends to sell or it is more likely than not that management will be required to sell prior to their anticipated recovery are recorded in other income, net. The Company segments its portfolio based on the underlying risk profiles of the securities and has a zero-loss expectation for U.S. treasury and U.S. government agency securities. The Company regularly reviews the securities in an unrealized loss position and evaluates the current expected credit loss by considering factors such as credit ratings, issuer-specific factors, current economic conditions, and reasonable and supportable forecasts. The Company did not record any material credit losses during the three months ended March 31, 2021.

Concentrations of credit risk
Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents, accounts receivable, and short-term investments. The Company places its cash and cash equivalents and short-term investments with well-established financial institutions.

One distribution partner accounted for 47% of total trade and other receivables, net as of March 31, 2021. Two distribution partners accounted for 11% and 28% of total trade and other receivables, net as of December 31, 2020. No customer accounted for more than 10% of the Company’s revenue in the periods presented.

Deferred commissions, net
Deferred commissions, net is stated as gross deferred commissions less accumulated amortization. Sales commissions earned by the Company’s sales force and third-party resellers, as well as related payroll taxes, are considered to be incremental and recoverable costs of obtaining a contract with a customer. These amounts have been capitalized as deferred commissions within prepaid and other current assets and other assets on the condensed consolidated balance sheets. The Company deferred incremental costs of obtaining a contract of $4.9 and $7.8 million during the three months ended March 31, 2021 and 2020, respectively.

Deferred commissions, net included in prepaid and other current assets were $27.1 million and $26.7 million as of March 31, 2021 and December 31, 2020, respectively. Deferred commissions, net included in other assets were $44.1 million and $47.3 million as of March 31, 2021 and December 31, 2020, respectively.

Commissions related to new contracts are typically deferred and amortized over a period of benefit of five years. The period of benefit was estimated by considering factors such as historical customer attrition rates, the useful life of the Company’s technology, and the impact of competition in its industry. Commissions that are commensurate with renewal commissions are typically amortized over one year. Amortized costs were $7.7 million and $5.1 million for the three months ended March 31, 2021 and 2020, respectively. Amortized costs are included in sales and marketing expense in the accompanying condensed consolidated statements of operations. There was no impairment loss in relation to the deferred costs for any period presented.

Property and equipment, net
Equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful life of the related asset, which is generally three to seven years. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or the term of the related lease.

The following table presents the estimated useful lives of property and equipment:

(Amounts in tables are in millions except per share data, or as otherwise noted)

The Company leases office space, data centers, and equipment under non-cancelable finance and operating leases with various expiration dates through 2036. The Company determines if an arrangement contains a lease at inception.

Operating lease right-of-use assets and lease liabilities are recognized at the present value of the future lease payments at commencement date. The interest rate implicit in the Company’s operating leases is not readily determinable, and therefore an incremental borrowing rate is estimated to determine the present value of future payments. The estimated incremental borrowing rate factors in a hypothetical interest rate on a collateralized basis with similar terms, payments, and economic environments. Operating lease right-of-use assets also include any prepaid lease payments and lease incentives.

Certain of the operating lease agreements contain rent concession, rent escalation, and option to renew provisions. Rent concession and rent escalation provisions are considered in determining the single lease cost to be recorded over the lease term. Single lease cost is recognized on a straight-line basis over the lease term commencing on the date the Company has the right to use the leased property. The lease terms may include options to extend or terminate the lease. The Company generally uses the base, non-cancelable, lease term when recognizing the lease assets and liabilities, unless it is reasonably certain that the option will be exercised.

In addition, certain operating lease agreements contain tenant improvement allowances from its landlords. These allowances are accounted for as lease incentives and decrease the Company's right-of-use asset and reduce single lease cost over the lease term.

As part of the Company's Virtual First strategy, Dropbox will retain a portion of its office space to be used for the Company’s team collaboration use and a portion will be marketed for sublease. During the first quarter of 2021, the Company recorded an impairment charge of $17.3 million related to right-of-use assets and other lease related property and equipment assets. During the fourth quarter of 2020, the Company recorded an impairment charge of $398.2 million related to right-of-use assets and other lease related property and equipment assets. These impairment charges were recorded in conjunction with the Company's decision to move towards a Virtual First work model. See Note 9 "Leases" for further information.

The Company leases certain equipment from various third parties, through equipment finance leases. These leases either include a bargain purchase option, a full transfer of ownership at the completion of the lease term, or the terms of the leases are at least 75 percent of the useful lives of the assets and are therefore classified as finance leases. These leases are capitalized in property and equipment, net and the related amortization of assets under finance leases is included in depreciation and amortization expense in the Company’s condensed consolidated statements of operations. Initial asset values and finance lease obligations are based on the present value of future minimum lease payments.

The Company’s finance lease agreements may contain lease and non-lease components. The non-lease components include payments for support on infrastructure equipment obtained via finance leases, which when not significant in relation to the overall agreement, are combined with the lease components and accounted for together as a single lease component.
Business combinations
The Company uses best estimates and assumptions, including but not limited to, future expected cash flows, expected asset lives, and discount rates, to assign a fair value to the tangible and intangible assets acquired and liabilities assumed in business combinations as of the acquisition date. These estimates are inherently uncertain and subject to refinement. During the measurement period, which may be up to one year from the acquisition date, adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed may be recorded, with the corresponding offset to goodwill.
Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s condensed consolidated statements of operations.

Long-lived assets, including goodwill and other acquired intangible assets, net
The Company evaluates the recoverability of its property and equipment and finite-lived intangible assets for possible impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable. The evaluation is performed at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Recoverability of these assets is measured by a comparison of the carrying amounts to the future

(Amounts in tables are in millions except per share data, or as otherwise noted)

undiscounted cash flows the assets are expected to generate. If such review determines that the carrying amount of specific property and equipment or intangible assets is not recoverable, the carrying amount of such assets is reduced to its fair value.

The Company reviews goodwill for impairment at least annually in the fourth quarter, or more frequently if events or changes in circumstances would more likely than not reduce the fair value of its single reporting unit below its carrying value.

The Company has not recorded impairment charges on goodwill or intangible assets for the periods presented in these condensed consolidated financial statements.

During the first quarter of 2021 and the fourth quarter of 2020, the Company recorded impairment charges in conjunction with the Company's decision to move towards a Virtual First work model. See Note 9 "Leases" for further information.

Acquired property and equipment and finite-lived intangible assets are amortized over their useful lives. The Company evaluates the estimated remaining useful life of these assets when events or changes in circumstances warrant a revision to the remaining period of amortization. If the Company revises the estimated useful life assumption for any asset, the remaining unamortized balance is amortized or depreciated over the revised estimated useful life on a prospective basis.

Income taxes
Deferred income tax balances reflect the effects of temporary differences between the financial reporting and tax bases of the Company’s assets and liabilities using enacted tax rates expected to apply when taxes are actually paid or recovered. In addition, deferred tax assets are recorded for net operating loss and credit carryforwards.

A valuation allowance is provided against deferred tax assets unless it is more likely than not that they will be realized based on all available positive and negative evidence. Such evidence includes, but is not limited to, recent cumulative earnings or losses, expectations of future taxable income by taxing jurisdiction, and the carry-forward periods available for the utilization of deferred tax assets.

The Company uses a two-step approach to recognizing and measuring uncertain income tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. The Company recognizes interest and penalties related to unrecognized tax benefits as income tax expense.

Although the Company believes that it has adequately reserved for its uncertain tax positions, it can provide no assurance that the final tax outcome of these matters will not be materially different. The Company evaluates its uncertain tax positions on a regular basis and evaluations are based on a number of factors, including changes in facts and circumstances, changes in tax law, such as the 2017 Tax Cuts and Jobs Act ("2017 Tax Reform Act"), the 2020 Coronavirus Aid, Relief, and Economic Security Act ("2020 CARES Act"), and the California 2020 Budget Act, correspondence with tax authorities during the course of an audit, and effective settlement of audit issues.

To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will affect the provision for income taxes in the period in which such determination is made and could have a material impact on the Company’s financial condition and results of operations.

Fair value measurement
The Company applies fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining fair value measurements for assets and liabilities, the Company considers the principal or most advantageous market in which it would transact and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as risks inherent in valuation techniques, transfer restrictions, and credit risk. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

Level 1—Quoted prices in active markets for identical assets or liabilities.
Level 2—Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3—Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability.

Recently adopted accounting pronouncements

In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). This ASU simplifies the accounting for convertible instruments and contracts in an entity’s own equity, as part of its overall simplification initiative to reduce costs and complexity of applying accounting standards while maintaining or improving the usefulness of the information provided to users of financial statements. Among other changes, the new guidance eliminates the requirement to separate the convertible debt into debt and equity components, unless the conversion feature is required to be bifurcated and accounted for as a derivative or the debt is issued at a substantial premium. As a result, after adopting the guidance, entities will no longer separately present such embedded conversion features in equity, and will instead account for the convertible debt wholly as debt. The ASU also removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more equity contracts to qualify for it. Lastly, entities are required to use the if-converted method for convertible instruments in the diluted earnings per share calculation. The guidance is effective for financial statements issued for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years, with early adoption permitted, but only at the beginning of the fiscal year. This update permits the use of either the modified retrospective or fully retrospective method of transition.

The Company early adopted this guidance as of January 1, 2021 using the modified retrospective approach. The adoption of the guidance did not have an impact on the Company’s financial statement as of the adoption date. As further discussed in Note 8 "Debt", the Company issued certain convertible senior notes and entered into certain contracts in the Company’s own equity during the quarter ending March 31, 2021, and the accounting for these instruments was based on the guidance in ASU 2020-06. Additionally, the impact on diluted earnings per share of the convertible senior notes was calculated based on the if-converted method, as further described in Note 13 "Net Income Per Share" for further information.

fair value is largely due to changes in credit spreads. The credit ratings associated with the corporate notes and obligations are mostly unchanged, are highly rated and the issuers continue to make timely principal and interest payments.

The Company recorded interest income from its cash, cash equivalents, and short-term investments of $1.9 million and $5.1 million during the three months ended March 31, 2021 and 2020, respectively.

Note 3.Fair Value Measurements

The Company measures its financial instruments at fair value each reporting period using a fair value hierarchy that prioritizes the use of observable inputs and minimizes 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.

The following table presents information about the Company’s financial instruments that are measured at fair value on a recurring basis using the input categories discussed in Note 1:
