ENPHASE ENERGY, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
1.
DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION
Description of Business
Enphase Energy, Inc. (the “Company”) is a global energy technology company. The Company delivers smart, easy-to-use solutions that manage solar generation, storage and communication on one intelligent platform. The Company revolutionized the solar industry with its microinverter technology and produces a fully integrated solar-plus-storage solution.
Basis of Presentation and Consolidation
The accompanying condensed consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States (“U.S.”), or GAAP. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Unaudited Interim Financial Information
These accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC for interim financial reporting. In the opinion of management, these unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal recurring items, considered necessary to present fairly the Company’s financial condition, results of operations, comprehensive income, stockholders’ equity and cash flows for the interim periods indicated. The results of operations for the three months ended March 31, 2020 are not necessarily indicative of the operating results for the full year.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Significant estimates and assumptions reflected in the financial statements include revenue recognition, allowance for doubtful accounts, stock-based compensation, inventory valuation, accrued warranty obligations, fair value of debt derivatives, fair value of acquired intangible assets and goodwill, useful lives of acquired intangible assets and property and equipment, incremental borrowing rate for right-of-use assets and lease liability, legal contingencies, and tax valuation allowance. These estimates are based on information available as of the date of the financial statements; therefore, actual results could differ materially from management’s estimates using different assumptions or under different conditions.
The worldwide spread of the COVID-19 pandemic is expected to result in a global slowdown of economic activity which is likely to decrease demand for a broad variety of goods and services, including from the Company’s customers, while also disrupting sales channels and marketing activities for an unknown period of time until the disease is contained. The Company expects this to have a negative impact on its sales and its results of operations. In preparing the Company’s condensed consolidated financial statements in accordance with GAAP, the Company is required to make estimates, assumptions and judgments that affect the amounts reported in its financial statements and the accompanying disclosures. Estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require the exercise of judgment. As of the date of issuance of these financial statements, the Company is not aware of any specific event or circumstance that would require the Company to update its estimates, judgments or revise the carrying value of its assets or liabilities. These estimates may change, as new events occur and additional information is obtained, and are recognized in the condensed consolidated financial statements as soon as they become known. Actual results could differ from those estimates and any such differences may be material to the Company’s financial statements.

Summary of Significant Accounting Policies
There have been no significant changes to the Company’s significant accounting policies in Note 2. “Summary of Significant Accounting Policies,” of the notes to consolidated financial statements included in Item 8 of the Company’s 2019 Annual Report on Form 10-K.
Recently Adopted Accounting Pronouncements
In August 2018, the FASB issued ASU 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract,” to reduce diversity in practice in accounting for the costs of implementing cloud computing arrangements that are service contracts. ASU 2018-15 allows entities to apply the guidance in the ASC 350-40, “Intangibles–Goodwill and Other–Internal-Use Software,” to determine which implementation costs are eligible to be capitalized as assets in a cloud computing arrangement that is considered a service contract. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. Entities have the option to apply the guidance prospectively to all implementation costs incurred after the date of adoption or retrospectively and are required to make certain disclosures in the interim and annual period of adoption. The Company adopted the new standard effective January 1, 2020 on a prospective basis and the adoption of this guidance did not have a material impact on its consolidated financial statements.
In June 2016, the FASB issued ASU 2016-13, “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with a current expected credit loss (CECL) model which will result in earlier recognition of credit losses. On January 1, 2020, the Company adopted Topic 326, the measurement of expected credit losses under the CECL model is applicable to financial assets measured at amortized cost, including accounts receivable. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

Amortization of developed technology, patents and licensed technology is recorded to sales and marketing expense. The developed technology acquired from the Company’s acquisition of SunPower Corporation’s (“SunPower”) microinverter business in August 2018 was embedded in the microinverters that SunPower sold to its customers. The Company does not actively use the developed technology acquired from SunPower and holds the developed technology to prevent others from using it. Accordingly, the Company accounts for the developed technology as a defensive intangible asset and amortizes the associated value over a period of six years from the date of acquisition.
The master supply agreement (“MSA”) entered into with SunPower in August 2018 provides the Company with the exclusive right to supply SunPower with module level power electronics for a period of five years, with options for renewals. The exclusivity arrangement extends throughout the term of the MSA, which comprises all of the expected cash flows from the customer relationship intangible asset, and was a condition to, and was an essential part of the acquisition of SunPower’s microinverter business by the Company. As the fair value ascribed to the customer relationship intangible asset represents payments to a customer, the Company amortizes the value of the customer relationship intangible asset as a reduction to revenue using a pattern of economic benefit method over a useful life of nine years.

FAIR VALUE MEASUREMENTS
The accounting guidance 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 the fair value measurements for assets and liabilities recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance.

The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. An asset’s or liability’s categorization 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—Valuations based on quoted prices in active markets for identical assets or liabilities that the Company is able to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of such assets or liabilities do not entail a significant degree of judgment.
Level 2—Valuations based on one or more quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.
Level 3—Valuations based on inputs that are unobservable and significant to the overall fair value measurement.
The following table presents the Company’s assets and liabilities that were measured at fair value on a recurring basis and its categorization within the fair value hierarchy.

Level 1. The Company's cash and cash equivalents primarily include highly liquid money market fund instruments and are within Level 1 of the fair value hierarchy because they are valued using quoted market prices for identical instruments in active markets. As of March 31, 2020, cash and cash equivalents balance includes money market funds of $542.2 million.
Level 2.
Convertible Notes due 2025 Derivatives
On March 9, 2020, the Company issued $320 million aggregate principal amount of 0.25% convertible senior notes due 2025 (the “Notes due 2025”) as further described in Note. 8 “Debt”. Concurrently with the issuance of the Notes due 2025, the Company entered into privately-negotiated convertible note hedge and warrant transactions which in combination are intended to reduce the potential dilution from the conversion of the Notes due 2025 and to effectively increase the overall conversion price from $81.54 to $106.94 per share. Initially, conversion of the Notes due 2025 will be settled solely in cash; however, following satisfaction of certain share reservation conditions (as defined in the relevant Indenture), conversion of the Notes due 2025 may be settled in cash, shares of the Company’s common stock or a combination of cash and shares of its common stock, at the Company’s election. The conversion option associated with the Notes due 2025 currently meets the criteria for an embedded derivative liability which required bifurcation and separate accounting. In addition, the privately-negotiated convertible note hedge and warrant transactions are also currently classified as a derivative asset and liability, respectively, on the Company’s condensed consolidated balance sheet. On the date the Company increases its authorized shares of common stock and satisfies the share reservation condition, the derivative asset and liabilities will be reclassified to additional paid-in capital as the equity classification criteria is met. Changes in the fair value of these derivatives prior to being classified in equity are reflected in other income (expense), net, in the Company’s condensed consolidated statement of operations.
The fair value of the Convertible notes embedded derivative is estimated using Binomial Lattice model and the fair value of Convertible notes hedge and Warrants liability is estimated using Black-Scholes-Merton model. Based on the fair value hierarchy, the Company classified the Convertible notes embedded derivative, Convertible notes hedge and Warrants liability derivatives (collectively the “derivatives”) to be Level 2 as significant inputs are observable, either directly or indirectly. The significant inputs and assumptions used in the models to calculate the fair value of the derivatives include the Company’s common stock price, exercise price of the derivatives, risk-free interest rate, volatility, annual coupon rate and remaining contractual term.
Notes due 2025 and Notes due 2024. The Company carries the Notes due 2025 and Notes due 2024 (as defined below) at face value less unamortized discount and issuance costs on its condensed consolidated balance sheets. The fair value of the Notes due 2025 and Notes due 2024 of $262.3 million and $252.9 million, respectively, was determined based on the closing trading prices per $100 principal amount as of the last day of trading for the period. The Company considers the fair value of the Notes due 2025 and Notes due 2024 to be a Level 2 measurement as they are not actively traded.
Level 3.
Warranty Obligations.
Fair Value Option for Warranty Obligations Related to Microinverters Sold Since January 1, 2014
The Company estimates the fair value of warranty obligations by calculating the warranty obligations in the same manner as for sales prior to January 1, 2014 and applying an expected present value technique to that result. The expected present value technique, an income approach, converts future amounts into a single current discounted amount. In addition to the key estimates of failure rates, claim rates and replacement costs, the Company used certain Level 3 inputs which are unobservable and significant to the overall fair value measurement. Such additional assumptions included a discount rate based on the Company’s credit-adjusted risk-free rate and compensation comprised of a profit element and risk premium required of a market participant to assume the obligation.

Sensitivity of Level 3 Inputs - Warranty Obligations
Each of the significant unobservable inputs is independent of the other. The profit element and risk premium are estimated based on requirements of a third-party participant willing to assume the Company’s warranty obligations. The credit‑adjusted risk‑free rate (“discount rate”) is determined by reference to the Company’s own credit standing at the fair value measurement date. Increasing the profit element and risk premium input by 100 basis points would result in a $0.2 million increase to the liability. Decreasing the profit element and risk premium by 100 basis points would result in a $0.2 million reduction of the liability. Increasing the discount rate by 100 basis points would result in a $0.9 million reduction of the liability. Decreasing the discount rate by 100 basis points would result in a $1.0 million increase to the liability.

Convertible Senior Notes due 2025
On March 9, 2020, the Company issued $320.0 million aggregate principal amount of the Notes due 2025. The Notes due 2025 are general unsecured obligations and bear interest at an annual rate of 0.25% per year, payable semi-annually on March 1 and September 1 of each year, beginning September 1, 2020. The Notes due 2025 are governed by an indenture between the Company and U.S. Bank National Association, as trustee. The Notes due 2025 will mature on March 1, 2025, unless earlier repurchased by the Company or converted at the option of the holders. The Company may not redeem the notes prior to the maturity date, and no sinking fund is provided for the notes. The Notes due 2025 may be converted, under certain circumstances as described below, based on an initial conversion rate of 12.2637 shares of common stock per $1,000 principal amount (which represents an initial conversion price of $81.54 per share). The conversion rate for the Notes due 2025 will be subject to adjustment upon the occurrence of certain specified events but will not be adjusted for accrued and unpaid interest. In addition, upon the occurrence of a make-whole fundamental change (as defined in the relevant indenture), the Company will, in certain circumstances, increase the conversion rate by a number of additional shares for a holder that elects to convert its notes in connection with such make-whole fundamental change. The Company received approximately $313.0 million in net proceeds, after deducting the initial purchasers’ discount, from the issuance of the Notes due 2025.

 
Enphase Energy, Inc. | 2020 Form 10-Q | 15

The Notes due 2025 may be converted prior to the close of business on the business day immediately preceding September 1, 2024, in multiples of $1,000 principal amount, at the option of the holder only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2020 (and only during such calendar quarter), if the last reported sale price of the Company’s 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 calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the “trading price” (as defined in the relevant indenture) 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 the Company’s common stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events. On and after September 1, 2024 until the close of business on the second scheduled trading day immediately preceding the maturity date of March 1, 2025, holders may convert their notes at any time, regardless of the foregoing circumstances. Upon the occurrence of a fundamental change (as defined in the relevant indenture), holders may require the Company to repurchase all or a portion of their Notes due 2025 for cash at a price equal to 100% of the principal amount of the notes to be repurchased plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date.
As of March 31, 2020, the number of authorized and unissued shares of the Company’s common stock that are not reserved for other purposes is less than the maximum number of underlying shares that will be required to settle the Notes due 2025 into equity. Accordingly, unless and until the Company has a number of authorized shares that have not been issued or reserved for any other purpose that equals or exceeds the maximum number of underlying shares (“share reservation condition”), the Company will pay to the converting holder in respect of each $1,000 principal amount of notes being converted solely cash in an amount equal to the sum of the daily conversion values for each of the 20 consecutive trading days during the related observation period. However, following satisfaction of the share reservation condition, the Company may settle conversions of notes through payment or delivery, as the case may be, of cash, shares of the Company’s common stock or a combination of cash and shares of its common stock, at the Company’s election.
In accounting for the issuance of the Notes due 2025, on March 9, 2020, the conversion option of the Notes due 2025 was deemed an embedded derivative requiring bifurcation from the Notes due 2025 (“host contract”) and separate accounting as an embedded derivative liability, as a result of the Company not having the necessary number of authorized but unissued shares of its common stock available to settle the conversion option of the Notes due 2025 in shares. The proceeds from the Notes due 2025 are first allocated to the embedded derivative liability and the remaining proceeds are then allocated to the host contract. On March 9, 2020, the carrying amount of the embedded derivative liability of $68.7 million representing the conversion option was determined using the Binomial Lattice model and the remaining $251.3 million was allocated to the host contract. The difference between the principal amount of the Notes due 2025 and the fair value of the host contract (the “debt discount”) is amortized to interest expense using the effective interest method over the term of the Notes due 2025.
As of March 31, 2020, the embedded derivative liability is included in Debt, non-current in the condensed consolidated balance sheet and the change in fair value of derivative is included in other income (expense), net in the condensed consolidated statement of operations.

Debt issuance costs for the issuance of the Notes due 2025 were approximately $7.6 million, consisting of initial purchasers' discount and other issuance costs. In accounting for the transaction costs, the Company allocated the total amount incurred to the Notes due 2025 host contract. Transaction costs were recorded as debt issuance cost (presented as contra debt in the condensed consolidated balance sheet) and are being amortized to interest expense over the term of the Notes due 2025.

Notes due 2025 Hedge and Warrant Transactions
In connection with the offering of the Notes due 2025, the Company entered into privately-negotiated convertible note hedge transactions pursuant to which the Company has the option to purchase a total of approximately 3.9 million shares of its common stock (subject to anti-dilution adjustments), which is the same number of shares initially issuable upon conversion of the notes, at a price of $81.54 per share, which is the initial conversion price of the Notes due 2025. The total cost of the convertible note hedge transactions was approximately $89.1 million. The convertible note hedge transactions are expected generally to reduce potential dilution to the Company’s common stock upon any conversion of the Notes due 2025 and/or offset any cash payments the Company is required to make in excess of the principal amount of converted notes, as the case may be. As of March 31, 2020, the Company had not purchased any shares under the convertible note hedge transactions.
Additionally, the Company separately entered into privately-negotiated warrant transactions (the “Warrants”) whereby the Company sold warrants to acquire approximately 3.9 million shares of the Company’s common stock (subject to anti-dilution adjustments) at an initial strike price of $106.94 per share. The Company received aggregate proceeds of approximately $71.6 million from the sale of the Warrants. If the market value per share of the Company’s common stock, as measured under the Warrants, exceeds the strike price of the Warrants, the Warrants will have a dilutive effect on the Company’s earnings per share, unless the Company elects, subject to certain conditions, to settle the Warrants in cash. Taken together, the purchase of the convertible note hedges and the sale of the Warrants are intended to reduce potential dilution from the conversion of the Notes due 2025 and to effectively increase the overall conversion price from $81.54 to $106.94 per share. The Warrants are only exercisable on the applicable expiration dates in accordance with the agreements relating to each of the Warrants. Subject to the other terms of the Warrants, the first expiration date applicable to the Warrants is June 1, 2025, and the final expiration date applicable to the Warrants is September 23, 2025. As of March 31, 2020, the Warrants had not been exercised and remained outstanding.
For the period from March 9, 2020, the issuance date of the convertible notes hedge and warrant transactions, through March 31, 2020, the number of authorized and unissued shares of the Company’s common stock that are not reserved for other purposes is less than the maximum number of underlying shares that will be required to settle the Notes due 2025 through the delivery of shares of the Company’s common stock. Accordingly, the convertibles note hedge transactions and the warrants may only be settled on net cash settlement basis. As a result the convertible note hedge transactions and the warrants have been classified as a Convertible notes hedge asset and Warrants liability, respectively, in the condensed consolidated balance sheet and the change in fair value of derivative is included in other income (expense), net in the condensed consolidated statement of operations.

Convertible Senior Notes due 2024
On June 5, 2019, the Company issued $132.0 million aggregate principal amount of 1.0% convertible senior notes due 2024 (the “Notes due 2024”). The Notes due 2024 are general unsecured obligations and bear interest at an annual rate of 1.0% per year, payable semi-annually on June 1 and December 1 of each year, beginning December 1, 2019. The Notes due 2024 are governed by an indenture between the Company and U.S. Bank National Association, as trustee. The Notes due 2024 will mature on June 1, 2024, unless earlier repurchased by the Company or converted at the option of the holders. The Company may not redeem the notes prior to the maturity date, and no sinking fund is provided for the notes. The Notes due 2024 may be converted, under certain circumstances as described below, based on an initial conversion rate of 48.7781 shares of common stock per $1,000 principal amount (which represents an initial conversion price of $20.5010 per share). The conversion rate for the Notes due 2024 will be subject to adjustment upon the occurrence of certain specified events but will not be adjusted for accrued and unpaid interest. In addition, upon the occurrence of a make-whole fundamental change (as defined in the relevant indenture), the Company will, in certain circumstances, increase the conversion rate by a number of additional shares for a holder that elects to convert its notes in connection with such make-whole fundamental change. The Company received approximately $128.0 million in net proceeds, after deducting the initial purchasers’ discount, from the issuance of the Notes due 2024.
The Notes due 2024 may be converted on any day prior to the close of business on the business day immediately preceding December 1, 2023, in multiples of $1,000 principal amount, at the option of the holder only under any of the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on September 30, 2019 (and only during such calendar quarter), if the last reported sale price of the Company’s 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 calendar quarter is greater than or equal to $26.6513 (130% of the conversion price) on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the “trading price” (as defined in the relevant indenture) 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 the Company’s common stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events. On and after December 1, 2023 until the close of business on the second scheduled trading day immediately preceding the maturity date of June 1, 2024, holders may convert their notes at any time, regardless of the foregoing circumstances. Upon the occurrence of a fundamental change (as defined in the relevant indenture), holders may require the Company to repurchase all or a portion of their Notes due 2024 for cash at a price equal to 100% of the principal amount of the notes to be repurchased plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date.
As of March 31, 2020, the sale price of the Company’s common stock was greater than or equal to $26.6513 (130% of the notes conversion price) for at least 20 trading days (whether consecutive or not) during a period of 30 consecutive trading days preceding the quarter-ended March 31, 2020. As a result, as of March 31, 2020, the Notes due 2024 became convertible at the holders’ option beginning on April 1, 2020 and ending June 30, 2020. Accordingly, the Company classified the net carrying amount of the Notes due 2024 of $97.9 million as Debt, current on the condensed consolidated balance sheet as of March 31, 2020.

In accounting for the issuance of the Notes due 2024, on June 5, 2019, the Company separated the Notes due 2024 into liability and equity components. The carrying amount of the liability component of approximately $95.6 million was calculated by using a discount rate of 7.75%, which was the Company’s borrowing rate on the date of the issuance of the notes for a similar debt instrument without the conversion feature. The carrying amount of the equity component of approximately $36.4 million, representing the conversion option, was determined by deducting the fair value of the liability component from the par value of the Notes due 2024. The equity component of the Notes due 2024 is included in additional paid-in capital in the condensed consolidated balance sheet and is not remeasured as long as it continues to meet the conditions for equity classification. The difference between the principal amount of the Notes due 2024 and the liability component (the “debt discount”) is amortized to interest expense using the effective interest method over the term of the Notes due 2024.
The Company separated the Notes due 2024 into liability and equity components, this resulted in a tax basis difference associated with the liability component that represents a temporary difference. The Company recognized the deferred taxes of $0.3 million for the tax effect of that temporary difference as an adjustment to the equity component included in additional paid-in capital in the condensed consolidated balance sheet.
Debt issuance costs for the issuance of the Notes due 2024 were approximately $4.6 million, consisting of initial purchasers' discount and other issuance costs. In accounting for the transaction costs, the Company allocated the total amount incurred to the liability and equity components using the same proportions as the proceeds from the Notes due 2024. Transaction costs attributable to the liability component were approximately $3.3 million, were recorded as debt issuance cost (presented as contra debt in the condensed consolidated balance sheet) and are being amortized to interest expense over the term of the Notes due 2024. The transaction costs attributable to the equity component were approximately $1.3 million and were netted with the equity component in stockholders’ equity. As of March 31, 2020 and December 31, 2019, the unamortized deferred issuance cost for the Notes due 2024 was $2.8 million and $2.9 million, respectively, on the condensed consolidated balance sheets.
The following table presents the total amount of interest cost recognized relating to the Notes due 2024:

The effective interest rate on the liability component Notes due 2024 was 7.75% for the three months ended March 31, 2020, which remains unchanged from the date of issuance. The remaining unamortized debt discount was $31.3 million and $32.9 million as of March 31, 2020 and December 31, 2019, respectively, will be amortized over approximately 4.2 years from March 31, 2020.
Notes due 2024 Hedge and Warrant Transactions
In connection with the offering of the Notes due 2024, the Company entered into privately-negotiated convertible note hedge transactions pursuant to which the Company has the option to purchase a total of approximately 6.4 million shares of its common stock (subject to anti-dilution adjustments), which is the same number of shares initially issuable upon conversion of the notes, at a price of $20.5010 per share, which is the initial conversion price of the Notes due 2024. The total cost of the convertible note hedge transactions was approximately $36.3 million. The convertible note hedge transactions are expected generally to reduce potential dilution to the Company’s common stock upon any conversion of the Notes due 2024 and/or offset any cash payments the Company is required to make in excess of the principal amount of converted notes, as the case may be. As of March 31, 2020, and through the date of this quarterly report, the Company had not purchased any shares under the convertible note hedge transactions.

ENPHASE ENERGY, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)


Additionally, the Company separately entered into privately-negotiated warrant transactions (the “Warrants”) whereby the Company sold warrants to acquire approximately 6.4 million shares of the Company’s common stock (subject to anti-dilution adjustments) at an initial strike price of $25.2320 per share. The Company received aggregate proceeds of approximately $29.8 million from the sale of the Warrants. If the market value per share of the Company’s common stock, as measured under the Warrants, exceeds the strike price of the Warrants, the Warrants will have a dilutive effect on the Company’s earnings per share, unless the Company elects, subject to certain conditions, to settle the Warrants in cash. Taken together, the purchase of the convertible note hedges and the sale of the Warrants are intended to reduce potential dilution from the conversion of the Notes due 2024 and to effectively increase the overall conversion price from $20.5010 to $25.2320 per share. The Warrants are only exercisable on the applicable expiration dates in accordance with the Warrants. Subject to the other terms of the Warrants, the first expiration date applicable to the Warrants is September 1, 2024, and the final expiration date applicable to the Warrants is April 22, 2025. As of March 31, 2020, and through the report date, the Warrants had not been exercised and remained outstanding.
Given that the transactions meet certain accounting criteria, the Notes due 2024 hedge and the warrants transactions are recorded in stockholders’ equity, and they are not accounted for as derivatives and are not remeasured each reporting period.
Convertible Senior Notes due 2023
In August 2018, the Company sold $65.0 million aggregate principal amount of 4.0% convertible senior notes due 2023 (the “Notes due 2023”) in a private placement. On May 30, 2019, the Company entered into separately and privately negotiated transactions with certain holders of the Notes due 2023 resulting in the repurchase and exchange, as of June 5, 2019, of $60.0 million aggregate principal amount of the notes in consideration for the issuance of 10,801,080 shares of common stock and separate cash payments totaling $6.0 million. As of both March 31, 2020 and December 31, 2019, $5.0 million aggregate principal amount of the Notes due 2023 remain outstanding.
The remaining outstanding Notes due 2023 are general unsecured obligations and bear interest at a rate of 4.0% per year, payable semi-annually on February 1 and August 1 of each year. The Notes due 2023 are governed by an indenture between the Company and U.S. Bank National Association, as trustee. The remaining outstanding Notes due 2023 will mature on August 1, 2023, unless earlier repurchased by the Company or converted at the option of the holders. The Company may not redeem the remaining Notes due 2023 prior to the maturity date, and no sinking fund is provided for such notes. The remaining Notes due 2023 are convertible, at a holder’s election, in multiples of $1,000 principal amount, into shares of the Company’s common stock based on the applicable conversion rate. The initial conversion rate for such notes is 180.0180 shares of common stock per $1,000 principal amount of notes (which is equivalent to an initial conversion price of approximately $5.56 per share). The conversion rate and the corresponding conversion price are subject to adjustment upon the occurrence of certain events but will not be adjusted for any accrued and unpaid interest. Holders of the remaining Notes due 2023 who convert their notes in connection with a make-whole fundamental change (as defined in the applicable indenture) are, under certain circumstances, entitled to an increase in the conversion rate. Additionally, in the event of a fundamental change, holders of the remaining Notes due 2023 may require the Company to repurchase all or a portion of their notes at a price equal to 100% of the principal amount of notes, plus any accrued and unpaid interest, including any additional interest to, but excluding, the repurchase date. Holders may convert all or any portion of their Notes due 2023 at their option at any time prior to the close of business on the business day immediately preceding the maturity date, in multiples of $1,000 principal amount.

Sale of Long-Term Financing Receivables
The Company entered into an agreement with a third party in the fourth quarter of 2017 to sell certain current and future receivables at a discount. In December 2017, the third party made an initial purchase of receivables that resulted in net proceeds to the Company of $2.8 million. This transaction was recorded as debt on the accompanying consolidated balance sheets, and the debt balance was relieved in January 2019 as the underlying receivables were settled. During the year ended December 31, 2018, the third party made three additional purchases of receivables that resulted in total net proceeds to the Company of $5.6 million. These transactions were recorded as debt on the accompanying condensed consolidated balance sheets, and the total associated debt balance will be relieved by September 2021 as the underlying receivables are settled.

INCOME TAXES
For the three months ended March 31, 2020, the Company’s income tax benefit of $11.9 million on income before income taxes of $57.1 million, calculated using the annualized effective tax rate method, was primarily due to tax deduction from employee stock compensation as a discrete event in the three months ended March 31, 2020, partially offset by projected tax expense in the United States (U.S.) and foreign jurisdictions that are profitable. For the three months ended March 31, 2019, the Company’s income tax provision of $0.3 million on income before income taxes of $3.1 million, calculated using the discrete tax approach, was primarily related to income taxes attributable to its foreign operations.
For the three months ended March 31, 2020, in accordance with FASB guidance for interim reporting of income tax, the Company has computed its provision for income taxes based on a projected annual effective tax rate while excluding loss jurisdictions which cannot be benefited.

 
Enphase Energy, Inc. | 2020 Form 10-Q | 25

ENPHASE ENERGY, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)



The Company used the discrete tax approach in calculating the tax expense for the three months ended March 31, 2019 due to the fact that a relatively small change in the Company’s projected pre-tax net income (loss) could result in a volatile effective tax rate. Under the discrete method, the Company determines its tax (expense) benefit based upon actual results as if the interim period was an annual period. The tax provision recorded was primarily related to income taxes attributable to its foreign operations.
12.
NET INCOME PER SHARE
Basic net income per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted net income per share is computed in a similar manner, but it also includes the effect of potential common shares outstanding during the period, when dilutive. Potential common shares include Stock Options, RSUs, PSUs, shares to be purchased under the Company’s ESPP, the Notes due 2023, the Notes due 2024 and warrants issued in conjunction with the Notes due 2024. Until the Company’s authorized shares of common stock increases to satisfy the share reservation condition, the Notes due 2025 and warrants issued in conjunction with the Notes due 2025 must be settled in cash, and therefore excluded from shares used in diluted per share amounts.
The dilutive effect of potentially dilutive common shares is reflected in diluted earnings per share by application of the treasury stock method for stock options, RSUs, PSUs, Notes due 2024, warrants issued in conjunction with the Notes due 2024 and shares to be purchased under the ESPP, and by application of the if-converted method for the Notes due 2023. To the extent these potential common shares are antidilutive, they are excluded from the calculation of diluted net income per share.

ENPHASE ENERGY, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)


Since the Company has the intent and ability to settle the aggregate principal amount of the Notes due 2024 in cash and any excess in shares of the Company’s common stock, the Company uses the treasury stock method for calculating any potential dilutive effect of the conversion spread on diluted net income per share, if applicable. In order to compute the dilutive effect, the number of shares included in the denominator of diluted net income per share is determined by dividing the conversion spread value of the “in-the-money” Notes due 2024 by the Company’s average share price during the period and including the resulting share amount in the diluted net income per share denominator. The conversion spread will have a dilutive impact on net income per share of common stock when the average market price of the Company’s common stock for a given period exceeds the conversion price of $20.5010 per share for the Notes due 2024. The Company’s weighted average common stock price since the issuance of the Notes due 2024 was above the conversion price, resulting in an impact on the diluted net income per share.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
Forward-Looking Statements
The following discussion and analysis of our financial condition and results of operations should be read together with our consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q. This discussion contains forward-looking statements reflecting our current expectations and involves risks and uncertainties. In some cases, you can identify forward-looking statements by terminology such as “may,” “will,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “intend,” “potential” or “continue” or the negative of these terms or other comparable terminology. Such statements, include but are not limited to statements regarding our expectations as to the impact of the COVID-19 pandemic, future financial performance, expense levels, liquidity sources, the capabilities and performance of our technology and products and planned changes, timing of new product releases, our business strategies, including anticipated trends, growth and developments in markets in which we target, the anticipated market adoption of our current and future products, performance in operations, including component supply management, product quality and customer service, and the anticipated benefits and risks relating to the transaction with SunPower Corporation. Our actual results and the timing of events may differ materially from those discussed in our forward-looking statements as a result of various factors, including those discussed below and those discussed in the section entitled “Risk Factors” included in this Quarterly Report on Form 10-Q and our Annual Report on Form 10-K for the fiscal year ended December 31, 2019.
Overview
We are a global energy technology company. We deliver smart, easy-to-use solutions that manage solar generation, storage and communication on one intelligent platform. We revolutionized the solar industry with our microinverter technology and we produce a fully integrated solar-plus-storage solution. We have shipped more than 27 million microinverters, and over 1.1 million Enphase residential and commercial systems have been deployed in more than 130 countries.
We sell our solutions primarily to distributors who resell them to solar installers. We also sell directly to large installers, OEMs, strategic partners and homeowners. Our revenue for the three months ended March 31, 2020 was positively impacted by the scheduled phase-down of the investment tax credit for solar projects under Section 48(a) (the “ITC”) of the Internal Revenue Code of 1986, as amended (the “Code”). The historical ITC percentage has decreased to 26% of the basis of a solar energy system that began construction during 2020, 22% for 2021, and zero for residential and 10% for commercial if construction begins after 2021 or if the solar energy system is placed into service after 2023. As a result, several of our customers explored opportunities to purchase products in 2019 to take advantage of safe harbor guidance from the IRS published in June 2018, allowing them to preserve the historical 30% investment tax credit for solar equipment purchased in 2019 for solar projects that are completed after December 31, 2019Safe harbor prepayments from customers in the fourth quarter of 2019 resulted in $44.5 million of revenue recognized in the three months ended March 31, 2020 when we delivered the product.
On March 9, 2020, we issued $320.0 million aggregate principal amount of our Convertible Senior Notes due 2025 (the “Notes due 2025”) in a private placement. The Notes due 2025 are general unsecured obligations and bear interest at a rate of 0.25% per year, payable semi-annually on March 1 and September 1 of each year, beginning on September 1, 2020. The Notes due 2025 will mature on March 1, 2025, unless earlier repurchased by us or converted at the option of the holders. Further information relating to the Notes due 2025 may be found in Note 8, “Debt,” of the notes to condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q and below under “Liquidity and Capital Resources.”
Impact of COVID-19
In March 2020, the outbreak of COVID-19 caused by a novel strain of the coronavirus was recognized as a pandemic by the World Health Organization, and the outbreak has become increasingly widespread globally, including in the core markets in which we operate. The COVID-19 outbreak has had a notable impact on general economic conditions, including but not limited to the temporary closures of many businesses, “shelter in place” and other governmental regulations, and reduced consumer spending. The most significant near-term impacts of COVID-19 on our financial performance are a decline in sales orders as future residential and commercial system owners are canceling sales meetings with system installation professionals or postponing system installations. As the purchase of new solar energy management solutions declines as part of COVID-19’s impacts on consumer spending, many businesses through which we distribute our products are working at limited operational capacity. The extent of the impact of

 
Enphase Energy, Inc. | 2020 Form 10-Q | 29


COVID-19 on our future operational and financial performance will depend on various future developments, including the duration and spread of the outbreak, impact on our employees, impact on our customers, effect on our sales cycles or costs, and effect on our supply chain and vendors, all of which are uncertain and cannot be predicted, but which could have a material adverse effect on our business, results of operations or financial condition. Further information relating to the risks and uncertainties related to the ongoing COVID-19 pandemic may be found in Part II, Item 1A “Risk Factors” of this Form 10-Q, as well as in the “Risk Factors” section in our 2019 Annual Report on Form 10-K that could be heightened due to duration and spread, among other impacts of the pandemic.
Products
We design, develop, manufacture and sell home energy solutions that manage energy generation, energy storage and control and communications on one intelligent platform. We have revolutionized the solar industry by bringing a systems approach to solar technology and by pioneering a semiconductor-based microinverter that converts energy at the individual solar module level and, combined with our proprietary networking and software technologies, provides advanced energy monitoring and control. This is vastly different than a central inverter system using string modules, with or without an optimizer, approach that only converts energy of the entire array of solar modules from a single high voltage electrical unit and lacks intelligence about the energy producing capacity of the solar array.
The Enphase Home Energy Solution with IQ™ platform enables self-consumption and delivers our core value proposition of yielding more energy, simplifying design and installation, and improving system uptime and reliability. The IQ™ family of microinverters, like all of our previous microinverters, is fully compliant with NEC 2014 and 2017 rapid shutdown requirements. Unlike string inverters, this capability is built-in, with no additional equipment necessary.
Our integrated approach to energy management helps to facilitate ease of installation and optimizing a home’s energy usage.  Enphase’s Always-On connected system also provides advanced monitoring and remote maintenance capabilities. The Enphase Home Energy Solution with IQ uses a single technology platform for seamless management of the whole solution, enabling rapid commissioning with the Installer Toolkit™ consumption monitoring with our Enphase Combiner 3C™ that includes the Envoy™ Communications Gateway, Enphase Enlighten™, a cloud-based energy management platform, Enphase IQ Combiner 3C™, designed to provide an uninterrupted connectivity to Enphase Enlighten, and our Enphase AC Battery™. System owners can use Enphase Enlighten to monitor their home’s solar generation, energy storage and consumption from any web-enabled device. Unlike some of our competitors, who utilize a traditional inverter, or offer separate components of solutions, we have built-in system redundancy in both PV generation and energy storage, eliminating the risk that comes with a single-point of failure. Further, the nature of our cloud-based, monitored system allows for remote firmware and software updates, enabling cost-effective remote maintenance and ongoing utility compliance.
The Enphase IQ 7™ microinverter and Enphase IQ 7+™ microinverter, part of our seventh-generation IQ™ product family, support high-powered 60-cell and 72-cell solar modules and integrate with alternating current (“AC”) modules. Our IQ 7X™ product addresses 96-cell photovoltaic (“PV”) modules up to 400W direct current (“DC”) and with its 97.5 percent California Energy Commission (“CEC”) efficiency rating, is ideal for integration into high power modules. Our IQ 7A™ microinverters are for solar modules up to 450 W, targeting high-power residential and commercial applications. Our customers should be able to pair the IQ 7A microinverter with monofacial or bifacial solar modules, up to 450 W, from solar module manufacturers who are expected to introduce high-power variants of their products in the next three years.
AC Module products are integrated systems which allow installers to be more competitive through improved logistics, reduced installation times, faster inspection and training. We continued to make steady progress during Q1’20 with our AC module partners, including SunPower, Panasonic Corporation of North America, LONGi Solar and Solaria Corporation.
Our next-generation IQ 8™ system is based upon our Always On Enphase Ensemble™ energy management technology. This system has five components: 1) energy generation, which is accomplished with the grid-agnostic microinverter IQ 8; 2) energy storage, which is achieved by the Encharge™ battery with capacities of 3.4 kWh and 10.1 kWh; 3) microgrid interconnect device (MID); 4) communication and control via the combiner box with the Envoy gateway; and 5) Enlighten, which is the internet of things, or IoT, cloud software.
Our next-generation battery in North America is Enphase Encharge 3™ or Encharge 10™ storage systems, with usable and scalable capacity of 3.4 kWh and 10.1 kWh, respectively. Enphase Encharge™ storage systems feature Enphase embedded grid-forming microinverters that enable the Always-On capability that keeps homes powered when the grid goes down, and the ability to save money when the grid is up. These systems are compatible with both new

Interest income of $1.1 million for the three months ended March 31, 2020 increased, as compared to $0.2 million in the same period in 2019, primarily due to interest earned on a higher average cash balance.
Interest expense of $3.2 million for the three months ended March 31, 2020 primarily includes $2.9 million related to the accretion of the debt discount, amortization of debt issuance cost and coupon interest incurred associated with our Notes due 2024 and Notes due 2025, $0.2 million of interest expense related to long-term financing receivable recorded as debt and interest expense of $0.1 million related to coupon interest incurred and amortization of debt issuance costs associated with our Notes due 2023. Interest expense of $3.8 million for the three months ended March 31, 2019 primarily includes interest expense of $2.8 million related to our Term Loans which were repaid in full on January 28, 2019 and $0.8 million related to coupon interest incurred and amortization of debt issuance costs associated with our Notes due 2023.
Other expense, net of $0.9 million for the three months ended March 31, 2020, relates to a net loss related to foreign currency exchange and remeasurement. Other expense, net of $0.5 million for the three months ended March 31, 2019, relates to a net loss related to foreign currency exchange and remeasurement.
The conversion option associated with the Notes due 2025 currently meets the criteria for an embedded derivative liability which required bifurcation and separate accounting. In addition, the privately-negotiated convertible note hedge and warrant transactions are also currently classified as a derivative asset and liability, respectively, on our condensed consolidated balance sheet as of March 31, 2020. On the date we increase our authorized shares of common stock and satisfy the share reservation condition, the derivative asset and liabilities will be reclassified to additional paid-in capital as the equity classification criteria is met. It is anticipated the share reservation condition will be satisfied promptly following our 2020 annual meeting of stockholders. Changes in the fair value of these derivatives prior to being classified in equity are reflected in other income (expense), net, in our condensed consolidated statement of operations. Change in fair value of derivatives of $15.3 million in the three months ended March 31, 2020 primarily includes the gain recognized for the change in fair value of our convertible notes embedded derivative and warrants of $23.6 million and $32.9 million, respectively. This gain is partially offset by a loss recognized for the change in fair value of our convertible notes hedge of $41.2 million.

Liquidity and Capital Resources
Sources of Liquidity
As of March 31, 2020, we had $549.1 million in cash and cash equivalents, $44.7 million in restricted cash and $518.1 million in working capital. Cash, cash equivalents and restricted cash held in the U.S. were $588.5 million and consisted primarily of U.S. government money market mutual funds and both interest-bearing and non-interest-bearing deposits, with the remainder held in various foreign subsidiaries. Restricted cash represents cash held by us in the form of a certificate of deposit collateralized under a letter of credit we issued to a customer that expired on April 30, 2020. We consider amounts held outside the U.S. to be accessible and have provided for the estimated U.S. income tax liability associated with our foreign earnings. However, our liquidity may be negatively impacted if sales decline significantly for an extended period due to the impact of the COVID-19 pandemic. Further, the extent to which the COVID-19 pandemic and our precautionary measures in response thereto impact our business and liquidity will depend on future developments, which are highly uncertain and cannot be precisely predicted at this time.
Convertible Notes
Notes due 2023. As of March 31, 2020, we had $5.0 million aggregate principal amount of our Notes due 2023 outstanding. The Notes due 2023 are general unsecured obligations and bear interest at a rate of 4.00% per year, payable semi-annually on February 1 and August 1 of each year. The Notes due 2023 will mature on August 1, 2023, unless earlier repurchased by us or converted at the option of the holders.
Notes due 2024. As of March 31, 2020, we had $132.0 million aggregate principal amount of our Notes due 2024 outstanding. The Notes due 2024 are general unsecured obligations and bear interest at a rate of 1.0% per year, payable semi-annually on June 1 and December 1 of each year. The Notes due 2024 will mature on June 1, 2024, unless earlier repurchased by us or converted at the option of the holders at a conversion price of $20.50 per share.
The Notes due 2024 may be converted on any day prior to the close of business on the business day immediately preceding December 1, 2023, in multiples of $1,000 principal amount, at the option of the holder only under any of the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on September 30, 2019 (and only during such calendar quarter), if the last reported sale price of the 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 calendar quarter is greater than or equal to $26.6513 (130% of the conversion price) on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the “trading price” (as defined in the relevant indenture) 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 the our common stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events. Upon conversion of any of the notes, we will pay or deliver, as the case may be, cash, shares of common stock or a combination of cash and common stock, at our election.
As of April 1, 2020 through June 30, 2020, the Notes due 2024 may be converted because the last reported sale price of our common stock for at least 20 trading days during a period of 30 consecutive trading days ending on March 31, 2020 was greater than or equal to $26.6513 on each applicable trading day. Upon conversion of any of the notes, we will pay or deliver, as the case may be, cash, shares of common stock or a combination of cash and common stock, at our election.
In connection with the offering of the Notes due 2024, we entered into privately-negotiated convertible note hedge transactions in order to reduce the potential dilution to our common stock upon any conversion of the Notes due 2024. Also, concurrently with the offering of the Notes due 2024, we entered into privately-negotiated warrant transactions whereby we issued warrants to effectively increase the overall conversion price of Notes due 2024 from $20.5010 to $25.2320.
As of May 5, 2020, the Notes due 2024 were not converted into equity, therefore, we had not purchased any shares under the convertible note hedge and the warrants had not been exercised and remain outstanding. If holders of the Notes due 2024 exercise their right to convert the debt to equity we have asserted our intent and ability to settle the $132.0 million aggregate principal amount of the Notes due 2024 in cash.

The Notes due 2025 are general unsecured obligations and bear interest at a rate of 0.25% per year, payable semi-annually on March 1 and September 1 of each year, beginning on September 1, 2020. The Notes due 2025 will mature on March 1, 2025, unless earlier repurchased by us or converted at the option of the holders at a conversion price of $81.54 per share.
The Notes due 2025 may be converted on any day prior to the close of business on the business day immediately preceding September 1, 2024, in multiples of $1,000 principal amount, at the option of the holder only under any of the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2020 (and only during such calendar quarter), if the last reported sale price of the 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 calendar quarter is greater than or equal to $81.5400 (130% of the conversion price) on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the “trading price” (as defined in the relevant indenture) 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 the our common stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events. Until, we satisfy share reservation condition, initially upon conversion of any of the notes, we will pay to the converting holder in respect of each $1,000 principal amount of notes being converted solely cash in an amount equal to the sum of the daily conversion values for each of the 20 consecutive trading days during the related observation period. However, following satisfaction of the share reservation condition, we will settle conversions of notes through payment or delivery, as the case may be, of cash, shares of our common stock or a combination of cash and shares of our common stock, at our election.
In connection with the offering of the Notes due 2025, we entered into privately-negotiated convertible note hedge transactions in order to reduce the potential dilution to our common stock upon any conversion of the Notes due 2025. The total cost of the convertible note hedge transactions was approximately $89.1 million. Also, concurrently with the offering of the Notes due 2025, we entered into privately-negotiated warrant transactions whereby we issued warrants to acquire shares of our common stock at a strike price of $106.9400 rather than the Notes due 2025 conversion price of $81.5400. We received approximately $71.6 million from the sale of the warrants.
As of May 5, 2020, the Notes due 2025 are not convertible into cash, therefore, we had not purchased any shares under the convertible note hedge and the warrants had not been exercised and remain outstanding. If holders of the Notes due 2025 are able to convert the debt to cash, and exercise that right, we have the ability to settle the $320.0 million aggregate principal amount of the Notes due 2025 in cash. See Note 8, “Debt,” of the notes to condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q for more information relating to the convertible note hedge transactions and warrants.
We believe that our existing cash, cash equivalents and restricted cash and cash flows from our operating activities will be sufficient to meet our anticipated cash needs for at least the next 12 months.

Cash Flows from Operating Activities
For the three months ended March 31, 2020, net cash provided by operating activities was $39.2 million compared to net cash provided by operating activities of $17.1 million in the same period 2019, an increase of $22.1 million quarter-over-quarter. The $22.1 million increase in net cash provided by operating activities in three months ended March 31, 2020 compared to the same period in 2019, was primarily due to higher profitability in the first quarter of 2020 of $66.2 million higher net income, partially offset by higher net non-cash benefit of $24.2 million and $19.8 million changes in working capital. The higher net non-cash benefit of $24.2 million in the first quarter of 2020, compared to the same period in 2019, primarily comprises of $15.3 million of gain due to change in the fair value of derivatives, $12.5 million higher deferred income tax benefit due to benefit from vesting of RSUs at higher stock price compared to grant date stock price and $2.2 million financing fees on extinguishment of debt in the three months ended March 31, 2019 not incurred in the same period in 2020, partially offset by higher non-cash charges for $4.2 million higher stock-based compensation, $1.2 million higher non-cash interest expense primarily due to debt discount on Notes due 2024 and Notes due 2025 and $0.3 million higher depreciation and amortization.
The $19.8 million net cash used due to changes in the working capital in the first quarter of 2020, compared to the same period in 2019, was primarily due to $38.0 million decrease in deferred revenue as we delivered safe harbor orders that were prepaid in the fourth quarter of 2019, $26.9 million decrease in accounts payable due to pay off of liabilities, $5.9 million increase in inventory and $2.6 million increase in prepaid expenses and other assets, partially offset by collections of $52.9 million of accounts receivable mainly driven by our safe harbor order deliveries in the first quarter of 2020 that was prepaid in the fourth quarter of 2019.
Cash Flows from Investing Activities
For the three months ended March 31, 2020, net cash used in investing activities was $3.4 million, primarily from purchases of test and assembly equipment to expand our supply capacity and related facility improvements, and capitalized costs related to internal-use software.
For the three months ended March 31, 2019, net cash used in investing activities of $0.7 million primarily resulted from purchases of test and assembly equipment and capitalized costs related to internal-use software.
Cash Flows from Financing Activities
For the three months ended March 31, 2020, net cash provided by financing activities of $262.1 million was primarily from $313.0 million net proceeds from the issuance of our Notes due 2025, $71.6 million from sale of warrants related to our Notes due 2025, $2.0 million net proceeds from employee stock option exercises and issuance of common stock under our employee stock incentive program, partially offset by $89.1 million purchase of convertible note bond hedge related to our Notes due 2025, $34.3 million payment of employee withholding taxes related to net share settlement of equity awards and $1.1 million of repayment on sale of long-term financing receivables.
For the three months ended March 31, 2019, net cash used by financing activities of $44.4 million was primarily from $44.7 million of principal payments on debts and financing fees associated with repayment of our term loan, which was partially offset by $0.3 million in net proceeds from sales of common stock under our employee stock incentive program.

Purchase obligations include amounts related to component inventory that our primary contract manufacturer procures on our behalf in accordance with our production forecast as well as other inventory related purchase commitments. The timing of purchases in future periods could differ materially from estimates presented above due to fluctuations in demand requirements related to varying sales levels as well as changes in economic conditions.
Off-Balance Sheet Arrangements
As of March 31, 2020, we did not have any off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of SEC Regulation S-K.
Critical Accounting Policies
Our condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the U.S., or GAAP. In connection with the preparation of our condensed consolidated financial statements, we are required to make assumptions and estimates about future events and apply judgments that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures. We base our assumptions, estimates and judgments on historical experience, current trends and other factors that management believes to be relevant at the time our condensed consolidated financial statements are prepared. On a regular basis, we review the accounting policies, assumptions, estimates and judgments to ensure that our condensed consolidated financial statements are presented fairly and in accordance with GAAP. However, because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates. To the extent that there are material differences between these estimates and actual results, our future financial statement presentation, financial condition, results of operations and cash flows will be affected.
The worldwide spread of the COVID-19 virus is expected to result in a global slowdown of economic activity which is likely to decrease demand for a broad variety of goods and services, including from our customers, while also disrupting sales channels and marketing activities for an unknown period of time until the disease is contained. We expect this to have a negative impact on our sales and our results of operations. In preparing our condensed consolidated financial statements in accordance with GAAP, we are required to make estimates, assumptions and judgments that affect the amounts reported in our financial statements and the accompanying disclosures. Estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require the exercise of judgment. As of the date of issuance of these financial statements, we are not aware of any specific event or circumstance that would require us to update our estimates, judgments or revise the carrying value of our assets or liabilities. These estimates may change, as new events occur and additional information is obtained, and are recognized in the condensed consolidated financial statements as soon as they become known. Actual results could differ from those estimates and any such differences may be material to our financial statements.
We consider an accounting policy to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, and if different estimates that reasonably could have been used, or changes in the accounting estimates that are reasonably likely to occur periodically, could materially impact the condensed consolidated financial statements.

Adoption of New and Recently Issued Accounting Pronouncements
Refer to Note 1. “Summary of Significant Accounting Policiesof the notes to condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q for a discussion of adoption of new and recently issued accounting pronouncements.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
For quantitative and qualitative disclosures about market risk, see Item 7A, “Quantitative and Qualitative Disclosures About Market Risk” of our Annual Report on Form 10‑K for the fiscal year ended December 31, 2019. Our exposures to market risk have not changed materially since December 31, 2019, except as described below.
Market Risk
On March 9, 2020, we issued $320 million aggregate principal amount of our Notes due 2025, and entered into privately-negotiated convertible note hedge and warrant transactions, which in combination are intended to reduce the potential dilution from the conversion of the Notes due 2025 and to effectively increase the overall conversion price from $81.54 to $106.94 per share. Unless and until we have number of authorized shares that have not been issued or reserved for any other purpose that equals or exceeds the maximum number of underlying shares required to settle our Notes due 2025 into equity, the embedded conversion option associated with the Notes due 2025, convertible notes hedge and warrants liability meet the criteria for derivative accounting, and as a result, derivative financial instruments are mark-to-market at each reporting period. The volatile market conditions arising from the COVID-19 pandemic may result in significant changes in the price of the our common stock and can cause variability in the fair value of these derivative financial instruments, thus materially affect our condensed consolidated statement of operations. Change in fair value of derivatives of $15.3 million in the three months ended March 31, 2020 primarily includes the gain recognized for the change in fair value of our convertible notes embedded derivative and warrants of $23.6 million and $32.9 million, respectively, partially offset by a loss recognized for the change in fair value of our convertible notes hedge of $41.2 million.
Credit Risk
Financial instruments that subject us to concentrations of credit risk consist primarily of cash and cash equivalents, accounts receivable, and derivative financial instruments. We maintain a substantial portion of our cash balances in non-interest-bearing and interest-bearing deposits and money market accounts. The derivative financial instruments expose us to credit risk to the extent that the counterparties may be unable to meet the terms of the arrangement. We mitigate this credit risk by transacting with major financial institutions with high credit ratings. We are not required to pledge, and are not entitled to receive, cash collateral related to these derivative instruments. We do not enter into derivative contracts for trading or speculative purposes. Our net revenues are primarily concentrated among a limited number of customers. We monitor the financial condition of our customers and perform credit evaluations whenever considered necessary and maintain an allowance for doubtful accounts for estimated potential credit losses.

 
Enphase Energy, Inc. | 2020 Form 10-Q | 38


Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2020. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, includes, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation of our disclosure controls and procedures as of March 31, 2020, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.
Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
Changes in Internal Control
There were no changes in our internal control over financial reporting identified in management’s evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the period covered by this Quarterly Report that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We have not experienced any material impact to our internal controls over financial reporting despite the fact that most of our employees are working remotely due to the COVID-19 pandemic. We are continually monitoring and assessing the impact of COVID-19 pandemic on our internal controls to minimize the impact on their design and operating effectiveness.

PART II. OTHER INFORMATION
Item 1. Legal Proceedings
From time to time, we may be involved in litigation relating to claims arising out of our operations. We are not currently involved in any material legal proceedings, and our management believes there are currently no claims or actions pending against us, the ultimate disposition of which could have a material adverse effect on our operations, financial condition, or cash flows. We may, however, be involved in material legal proceedings in the future. Such matters are subject to uncertainty and there can be no assurance that such legal proceedings will not have a material adverse effect on our business, results of operations, financial position or cash flows.
Item 1A. Risk Factors
Other than risk factors described below, there has been no material changes in our risk factors from those disclosed in Part I, Item 1A, in our Annual Report on Form 10‑K for the fiscal year ended December 31, 2019.
The current COVID-19 pandemic, as well as other actual or threatened epidemics, pandemics, outbreaks, or public health crises, may adversely affect our customers’ financial condition and our business.
The worldwide spread of the COVID-19 pandemic has resulted in a global slowdown of economic activity which is likely to decrease demand for a broad variety of goods and services, including from our customers, while also disrupting sales channels and marketing activities for an unknown period of time until the disease is contained. We expect this to have a negative impact on our sales and its results of operations, the size and duration of which we are currently unable to predict.
Among other impacts, the COVID-19 pandemic and associated governmental orders have slowed, and could continue to slow the rate of solar installations, reduce demand for our products and cause temporary or long-term disruptions in our supply chains and/or delays in the delivery of our inventory. Further, such risks could also adversely affect our customers' financial condition, resulting in reduced spending for the solar products we sell. Moreover, COVID-19 and associated governmental orders could require or cause employees to avoid our properties, which could adversely affect our ability to adequately staff and manage our businesses. “Shelter-in-place” or other such orders by governmental entities could also disrupt our operations, if employees who cannot perform their responsibilities from home, are not able to report to work.  Risks related to COVID-19 could also lead to the complete or partial closure of one or more of our facilities or operations of our customers, suppliers, vendors or other partners.
The ultimate extent of the impact of COVID-19 on our business, financial condition and results of operations will depend on future developments, including that are highly uncertain and cannot be predicted with confidence at this time, including ultimate duration of the pandemic, travel restrictions, quarantines, social distancing and business closure requirements in the U.S. and other countries, and the effectiveness of actions taken globally to contain and treat the disease. These and other potential impacts of COVID-19, could therefore materially and adversely affect our business, financial condition and results of operations.
To the extent the COVID-19 pandemic adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described in this ‘‘Risk Factors’’ section as well as our risk factors from disclosed in our Annual Report on Form 10K for the fiscal year ended December 31, 2019, such reduced spending for solar energy systems, fluctuations in customer demand, and manufacturing and supply constraints.
The foregoing risks will also likely apply to any other future epidemic, pandemic, outbreak or other public health crisis.
Our business is affected by worldwide economic and market conditions; an unstable economy, a decline in consumer-spending levels and other adverse developments, including inflation, could lead to reduced revenues and gross margins and adversely affect our business, results of operations and liquidity.
Many economic and other factors are outside of our control, including general economic and market conditions, consumer and commercial credit availability, inflation, unemployment, consumer debt levels and other challenges affecting the global economy including the COVID-19 pandemic. Increases in the rates of unemployment, decreases in home values, decrease in new home construction, reduced access to credit and issues related to the domestic and international political situations may adversely affect consumer confidence and disposable income levels. Early societal responses to the COVID-19 pandemic have involved business closures and limited social interaction as well as work

 
Enphase Energy, Inc. | 2020 Form 10-Q | 40


reductions.  Low consumer confidence and disposable incomes could lead to reduced consumer spending and lower demand for our products, which are discretionary items, the purchase of which can be reduced before customers adjust their budgets for necessities. These factors could have a negative impact on our sales and cause us to increase inventory markdowns and promotional expenses, thereby reducing our gross margins and operating results.
If demand for solar energy solutions decreases as a result of the consequences of the COVID-19 pandemic, our business will suffer.
Our success depends on continued demand for solar energy solutions and the ability of solar equipment vendors to meet this demand. As a consequence of the COVID-19 pandemic, the demand for solar energy solutions may decrease, or at least not continue its growth from recent years, as a result of government orders associated with COVID-19, due to adverse worldwide economic and market conditions, or other factors. If demand for solar energy solutions decreases or does not grow, demand for our customers’ products as well as demand for our products will decrease, which would have an adverse impact on our ability to increase our revenue and grow our business.
Natural disasters, public health events, significant disruptions of information technology systems, data security breaches, or other catastrophic events could adversely affect our operations.
Our worldwide operations could be subject to natural disasters, public health events and other business disruptions, which could harm our future revenue and financial condition and increase our costs and expenses. For example, our corporate headquarters in Fremont, California is located near major earthquake fault lines and our Petaluma, California facility is near fault lines and the sites of recent catastrophic wild fires. We rely on third-party manufacturing facilities including for all product assembly and final testing of our products, which are performed at third-party manufacturing facilities, in China and Mexico. There may be conflict or uncertainty in the countries in which we operate, including public health issues (for example, the ongoing COVID-19 pandemic or an outbreak of other contagious diseases or health epidemics), safety issues, natural disasters, fire, disruptions of service from utilities, nuclear power plant accidents or general economic or political factors. Such risks could result in an increase in the cost of components, production delays, general business interruptions, delays from difficulties in obtaining export licenses for certain technology, tariffs and other barriers and restrictions, longer payment cycles, increased taxes, restrictions on the repatriation of funds and the burdens of complying with a variety of foreign laws, any of which could ultimately have a material adverse effect on our business.
Further, any terrorist attacks, material disruption to our information technology systems or any data security breaches, including due to cyber-attacks, especially any aimed at energy or communications infrastructure suppliers or our cloud-based monitoring service, could hinder or delay the development and sale or performance of our products or otherwise adverse affect us. Such significant disruptions of our, our third party vendors’ and/or business partners’ information technology systems or data security breaches, including in our remote work environment as a result of COVID-19, could adversely affect our business operations and/or result in the loss, misappropriation, and/or unauthorized access, use or disclosure of, or the prevention of access to, confidential information (including trade secrets or other intellectual property, proprietary business information and personal information), and could result in financial, legal, business and reputational harm to us. Any such event that leads to unauthorized access, use or disclosure of personal information, including personal information regarding our customers, could harm our reputation, compel us to comply with federal and/or state breach notification laws and foreign law equivalents, subject us to mandatory corrective action, require us to verify the correctness of database contents and otherwise subject us to liability under laws and regulations that protect the privacy and security of personal information, which could disrupt our business, result in increased costs or loss of revenue, and/or result in legal and financial exposure. In addition, security breaches and other inappropriate access can be difficult to detect, and any delay in identifying them may further harm us. Moreover, the prevalent use of mobile devices to access confidential information increases the risk of security breaches. While we have implemented security measures to protect our information technology systems and infrastructure, there can be no assurance that such measures will prevent service interruptions or security breaches that could adversely affect our business. In addition, failure to maintain effective internal accounting controls related to security breaches and cybersecurity in general could impact our ability to produce timely and accurate financial statements and subject us to regulatory scrutiny.
In the event that natural disasters, public health epidemics or technical catastrophes were to damage or destroy any part of our facilities or those of our contract manufacturer, destroy or disrupt vital infrastructure systems or interrupt our operations or services for any extended period of time, our business, financial condition and results of operations would be materially and adversely affected.

 
Enphase Energy, Inc. | 2020 Form 10-Q | 41


Conversion of our Convertible Notes may dilute the ownership interest of existing stockholders or may otherwise depress the price of our common stock.
In March 2020, we issued and sold a total of $320.0 million aggregate principal amount of our Notes due 2025.
In June 2019, we issued and sold a total of $132.0 million aggregate principal amount of our Notes due 2024.
As of March 31, 2020,
$5.0 million aggregate principal amount of the Notes due 2023 were outstanding;
$132.0 million aggregate principal amount of the Notes due 2024 were outstanding; and
$320.0 million aggregate principal amount of the Notes due 2024 were outstanding (the foregoing, collectively, the “Convertible Notes”)
The conversion of some or all of the Convertible Notes may dilute the ownership interests of existing stockholders. Any sales in the public market of the common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, the existence of the Convertible Notes may encourage short selling by market participants because the conversion of the Convertible Notes could be used to satisfy short positions. In addition, the anticipated conversion of the Convertible Notes into shares of our common stock could depress the price of our common stock.
Servicing our debts requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay our debts.
Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness, including the Convertible Notes, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to service our debts, including the Convertible Notes, and make necessary capital expenditures. If we are unable to generate cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness, including the Convertible Notes, will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of those activities or engage in these activities on desirable terms, which could result in a default on our debt obligations, including our obligations under the Convertible Notes.
As of the reporting date, the number of authorized and unissued shares of our common stock that are not reserved for other purposes is less than the maximum number of underlying shares that will be required to settle the Notes due 2025 into equity. Accordingly, unless and until we have a number of authorized shares that have not been issued or reserved for any other purpose that equals or exceeds the maximum number of underlying shares, holder of the notes may convert the notes solely into cash based on the conversion rate and only under certain circumstances as described herein. Following satisfaction of the share reservation condition, until we elect to satisfy all or a portion of our conversion obligation through delivery of our common stock, holder of the notes are not entitled to any rights with respect to our common stock (including, without limitation, voting rights and rights to receive any dividends or other distributions on our common stock) as a result of the ownership, or upon conversion, of notes. However, the value of notes may be impacted by changes affecting our common stock.
We may not have the ability to raise the funds necessary to repurchase the Convertible Notes upon a fundamental change or to repay the Notes due 2025, Notes due 2024 and the Notes due 2023 at maturity.
Holders of our Convertible Notes will have the right to require us to repurchase all or a portion of their convertible notes upon the occurrence of a fundamental change at 100% of the principal amount of the Notes due 2025, Notes due 2024 and Notes due 2023, plus accrued and unpaid interest. Fundamental change is defined in each of the Convertible Notes Indenture entered into in connection with the financing and consists of events such as an acquisition of a majority of our outstanding common stock, an acquisition of our company or substantially all of our assets, the approval by our stockholders of a plan of liquidation or dissolution, or our common stock no longer being listed on the Nasdaq Global Select Market or the Nasdaq Global Market. We may not have enough available cash or be able to obtain financing at the time we are required to make such repurchase of the Convertible Notes.
Our ability to raise additional capital may also be adversely impacted by potential worsening global economic conditions and potential future disruptions to, and volatility in, the credit and financial markets in the U.S. and worldwide resulting from the ongoing COVID-19 pandemic. If we do not have enough available cash at the time we are required to make the required repurchases of the Convertible Notes, we may be required to undertake one or more actions,

 
Enphase Energy, Inc. | 2020 Form 10-Q | 42


such as selling assets, attempting to restructure the Convertible Notes or other debt, or obtaining additional capital on terms that may be onerous or highly dilutive. Any such actions could have a material adverse effect on our business, financial condition or results of operations.
The convertible note hedge and warrant transactions and/or their early termination may affect the value of our common stock.
In connection with the offering of the Notes due 2025 and Notes due 2024, we entered into privately negotiated convertible note hedge transactions pursuant to which we have the option to purchase approximately the same number of shares of our common stock initially issuable upon conversion of the Notes due 2025 and Notes due 2024, at a price approximately the same as the initial conversion price of the Notes due 2025 and Notes due 2024. These transactions are expected to reduce the potential dilution with respect to our common stock upon conversion of the Notes due 2025 and Notes due 2024. Separately, we also entered into privately negotiated warrant transactions to acquire the same number of shares of our common stock initially issuable upon conversion of the Notes due 2025 and Notes due 2024 (subject to customary anti-dilution adjustments) at an initial strike price of approximately $106.94 per share and $25.23 per share for Notes due 2025 and Notes due 2024, respectively. If the market value per share of our common stock, as measured under the warrants, exceeds the strike price of the warrants, the warrants will have a dilutive effect on the ownership interests of existing stockholders and on our earnings per share, unless we elect, subject to certain conditions, to settle the warrants in cash. However, we may not have enough available cash or be able to obtain financing at the time of settlement.
In addition, the existence of the convertible note hedge and warrant transactions may encourage purchasing and selling share of our common stock, or other of our securities and instruments, in open market and/or privately negotiated transactions in order to modify hedge positions. Any of these activities could adversely affect the value of our common stock and the value of the Notes due 2025 and Notes due 2024.
Changes in current accounting methods, standards, or regulations applicable to the Convertible Notes due 2024 and Notes due 2025 could have a material impact on our reported financial results, future financial results, future cash flows, and/or our stock price.
Under Accounting Standards Codification (“ASC”) 470-20, “Debt with Conversion and Other Options,” an entity must separately account for the host contract and conversion option associated with convertible debt instruments, such as the Notes due 2025 and Notes due 2024, that may be settled entirely or partially in cash upon conversion, in a manner that reflects the issuer’s economic interest cost. For Notes due 2024, conversion option meets the classification of an equity component, hence we have included the equity component in the additional paid-in capital section of stockholders’ equity on our condensed consolidated balance sheet at the issuance date. For Notes due 2025, conversion option meets the classification of an embedded derivative liability, and hence we have included embedded derivative liability in the Debt, non-current on our condensed consolidated balance sheet at the issuance date. We have treated the value of the equity component and embedded derivative liability as debt discount for the host contract. We are required to amortize the debt discount as non-cash interest expense over the term of the Notes due 2025 and Notes due 2024, which could adversely affect our reported or future financial results or the trading price of our common stock.
In addition, we use the treasury stock method for convertible debt instruments (such as the Notes due 2024) that may be settled entirely or partly in cash, and the effect of which is that any shares issuable upon conversion of the notes are not included in the calculation of diluted earnings per share except to the extent that the conversion value of such notes exceeds their principal amount. Under the treasury stock method, for diluted earnings per share purposes, the transaction is accounted for as if the number of shares of common stock that would be necessary to settle such excess conversion value, if we elected to settle such excess in shares, are issued. We cannot be sure that the accounting standards in the future will continue to permit use of the treasury stock method. If we are unable to use the treasury stock method in accounting for the shares issuable upon conversion of the Notes due 2024, then our diluted earnings per share will be adversely affected. Until we satisfy share reservation condition, Notes due 2025 initially upon conversion of any of the notes are solely convertible into cash.

Accounting Standards Update (“ASU”) 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments,” clarifies how certain cash receipts and payments should be classified in the statement of cash flows, including the cash settlement for our Notes due 2024 and Notes due 2025. Upon cash settlement, repayment of the principal amount will be bifurcated between cash outflows for operating activities for the portion related to accreted interest attributable to debt discounts arising from the difference between the coupon interest rate and the effective interest rate, and financing activities for the remainder. This will require us to classify the $36.4 million for Notes due 2024 and $68.7 million for Notes due 2025 of accreted interest as cash used in operating activities in our consolidated statement of cash flows upon cash settlement, which could adversely affect our future cash flow from operations.
The accounting for the notes will result in our having to recognize interest expense significantly more than the stated interest rate of the notes and may result in volatility to our condensed consolidated statement of operations. Also, the accounting method for instruments that must be settled in cash, such as the note conversion option and the convertible note hedge transactions, will have a material effect on our reported financial results.
On May 20, 2020, at our Annual Meeting of shareholders, the stockholders will vote on a proposal to amend our certificate of incorporation to increase the number of authorized shares of our common stock from 150 million shares to 200 million shares. Unless we obtain such stockholder approval, we will settle any conversions of the Notes due 2025 entirely in cash. Until we obtain such stockholder approval, the ability of holders of the notes to convert the notes at their option in certain circumstances, which we refer to as the “conversion option,” will be accounted for as a derivative. In general, this require us to establish a separate initial valuation of the conversion option and to bifurcate this value from the value attributable to the balance of the notes, or the debt component. As a result, for accounting purposes, we are required to treat the notes as having been issued with a discount to their face principal amount, which is referred to as a debt discount. We are required to accrete the debt discount to interest expense over the term of the notes based on an effective interest rate for the notes in our condensed consolidated statement of operations that is in excess of the stated coupon rate of the notes. This will reduce our earnings and could adversely affect the price at which our common stock trades, but will have no effect on the amount of cash interest paid to holders or on our cash flows.
For each financial statement period over the term of the notes, a gain (or loss) will be reported in our consolidated statement of operations to the extent the valuation of the conversion option changes from the previous period. The convertible note hedge and warrants transactions will also be accounted for as derivatives. We expect gains and losses on the convertible note hedge to partially, but not entirely offset the gain (or loss) associated with changes to the valuation of the conversion option. Changes in the price of our common stock and changes in our credit risk, or the credit risk of the counterparties to the convertible note hedge and warrants transactions, can cause variability in the value of these instruments. Should there be significant changes in the price of our common stock, our credit risk, or the credit risk of such counterparties, such changes will result in valuation volatility that could materially affect our consolidated statement of operations.
Upon, receiving stockholder’s approval to increase the number of authorized shares of our common stock as described herein, then, assuming all of the other requirements for equity classification under ASC 815-40 are met, both the derivative liability and derivative asset related to the conversion option and the convertible note hedge transactions may be reclassified to equity and subsequently, provided all of the requirements for equity classification are met prospectively, no additional gain (or loss) from these derivatives will be reported in our consolidated statement of operations. However, the original issuance discount on the notes will continue to be accreted to interest expense over the remaining term of the notes.
Even if we obtain the stockholder approval described herein, we may not meet all of the other equity classification requirements at that point in time or thereafter. If we do not continue to satisfy all of the criteria required for equity classification, the conversion option and the convertible note hedge transactions will continue not to be classified as equity or may be reclassified out of equity and be subject to re-measurement. Similarly, while we expect to meet the equity classification guidance with regards to the warrants at the inception of the arrangement, if we do not continue to satisfy all of the criteria required for equity classification, the warrants too may be reclassified out of equity and become subject to re-measurement. Changes in fair value resulting from any such re-measurement will be reflected in our consolidated statement of operations.
