Notes to the Condensed Consolidated Financial Statements

Note 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization

SunPower Corporation (together with its subsidiaries, "SunPower," "we," "us," and "our") is a leading global energy company that delivers complete solar solutions to residential, commercial, and power plant customers worldwide through an array of hardware, software, and financing options and through solar power solutions, operations and maintenance ("O&M") services, and "Smart Energy" solutions. SunPower's Smart Energy initiative is designed to add layers of intelligent control to homes, buildings and grids - all personalized through easy-to-use customer interfaces. Of all the solar cells commercially available to the mass market, we believe our solar cells have the highest solar power conversion efficiency, a measurement of the amount of sunlight converted by the solar cell into electricity. SunPower is a majority-owned subsidiary of Total Solar International SAS ("Total"), formerly Total Energies Nouvelles Activités USA, a subsidiary of Total S.A. ("Total S.A.") (see "Note 2. Transactions with Total and Total S.A").

Liquidity

Challenging industry conditions and a competitive environment extended throughout fiscal 2018 and the first quarter of fiscal 2019. Our net losses, resulting in a net use of our available cash, continued in the first quarter of fiscal 2019 and are expected to continue through the remainder of fiscal 2019. Despite the challenging industry conditions, including uncertainty around the regulatory environment, we believe that our cash and cash equivalents, including cash expected to be generated from operations, will be sufficient to meet our obligations over the next 12 months from the date of the issuance of our financial statements. We have been successful in our ability to divest certain investments and non-core assets, such as the divestiture of our equity interest in 8point3 Energy Partners LP, the sale of certain assets and intellectual property related to the production of microinverters, the sale of membership interests in our Residential Lease Portfolio, and the sale of membership interests in our Commercial Sale-Leaseback Portfolio (Note 4. Business Divestiture). Additionally, we have secured other sources of financing in connection with our liquidity needs, as well as realizing cash savings resulting from restructuring actions and cost reduction initiatives (Note 11. Debt and Credit Sources). We continue to focus on improving our overall operating performance and liquidity, including managing cash flow and working capital.

We also have the ability to enhance our available cash by borrowing up to $95.0 million under a revolving credit facility (the "Revolver") with Credit Agricole Corporate and Investment Bank ("Credit Agricole") pursuant to a Letter Agreement executed by us and Total S.A. on May 8, 2017 (the "Letter Agreement") through August 26, 2019, the expiration date of the Letter Agreement.

Although we have historically been able to generate liquidity, we cannot predict, with certainty, the outcome of our actions to generate liquidity as planned.

Basis of Presentation and Preparation

Principles of Consolidation

The accompanying condensed consolidated financial statements include the accounts of SunPower and our wholly-owned subsidiaries, and have been prepared by us in accordance with generally accepted accounting principles in the United States ("United States" or "U.S.," and such accounting principles, "U.S. GAAP") for interim financial information, and include the accounts of SunPower, all of our subsidiaries and special purpose entities, as appropriate under U.S. GAAP. All intercompany transactions and balances have been eliminated in consolidation. The financial information included herein is unaudited, and reflects all adjustments which are, in the opinion of our management, of a normal recurring nature and necessary for a fair statement of the results for the periods presented. The December 30, 2018 consolidated balance sheet data were derived from SunPower’s audited consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 30, 2018, as filed with the Securities and Exchange Commission ("SEC") on February 13, 2019, but do not include all disclosures required by U.S. GAAP. The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in SunPower's Annual Report on Form 10-K for the fiscal year ended December 30, 2018. The operating results for the fiscal quarter ended March 31, 2019 are not necessarily indicative of the results that may be expected for fiscal year 2019, or for any other future period.

Certain prior period balances have been reclassified to conform to the current period presentation in our condensed consolidated financial statements and the accompanying notes.

Table of Contents

We have a 52-to-53-week fiscal year that ends on the Sunday closest to December 31. Accordingly, every fifth or sixth year will be a 53-week fiscal year. Both fiscal 2019 and 2018 are 52-week fiscal years. The first quarter of fiscal 2019 ended on March 31, 2019, while the first quarter of fiscal 2018 ended on April 1, 2018.

Management Estimates

The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires our management to make estimates and assumptions that affect the amounts reported in these condensed consolidated financial statements and accompanying notes. Significant estimates in these condensed consolidated financial statements include revenue recognition, specifically the nature and timing of satisfaction of performance obligations, standalone selling price of performance obligations and variable consideration; allowances for doubtful accounts receivable; recoverability of financing receivables related to residential leases; inventory and project asset write-downs; stock-based compensation; long-lived asset impairment, specifically estimates for valuation assumptions including discount rates and future cash flows; economic useful lives of property, plant and equipment, and intangible assets, fair value of investments including an equity investment for which we apply the fair value option and other financial instruments; residual value of solar power systems, including those subject to residential operating leases; valuation of contingencies such as accrued warranty; the incremental borrowing rate used in discounting of lease liabilities; the fair value of indemnities provided to customers and other parties, and income taxes and tax valuation allowances. Actual results could materially differ from those estimates.

Summary of Significant Accounting Policies

Lease Accounting

Effective December 31, 2018, we adopted Accounting Standards Update ("ASU") No. 2016-02, Leases (Topic 842), as amended ("ASC 842"). For additional information on the changes resulting from the new standard and the impact to our financial results on adoption, refer to the section Recently Adopted Accounting Pronouncements below.

Arrangements with SunPower as a lessee

We determine if an arrangement is a lease at inception. Our operating lease agreements are primarily for real estate and are included within operating lease right-of-use ("ROU") assets and operating lease liabilities on the consolidated balance sheets. We elected the practical expedient to combine our lease and related non-lease components for all our leases.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. Variable lease payments are excluded from the ROU assets and lease liabilities and are recognized in the period in which the obligation for those payments is incurred. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. ROU assets also include any lease prepayments made and exclude lease incentives. Many of our lessee agreements include options to extend the lease, which we do not include in our minimum lease terms unless they are reasonably certain to be exercised. Rental expense for lease payments related to operating leases is recognized on a straight-line basis over the lease term.

Sale-Leaseback Arrangements

We enter into sale-leaseback arrangements under which solar power systems are sold to third parties and subsequently leased back by us over lease terms of up to 25 years. At the end of the lease term, we have the option to purchase the systems at fair value or may be required to remove the systems and return them to the third parties.

We classify our sale-leaseback arrangements of solar power systems as operating leases or sales-type leases, in accordance with the underlying accounting guidance on leases.

For all sale-leaseback arrangements classified as operating leases, the deferred profit on the sale of the underlying systems is recognized over the term of the lease. Sale-leaseback arrangements classified as sales-type leases or failed sale, are accounted for under the financing method, the proceeds received from the sale of the solar power systems are recorded by us as financing liabilities. The financing liabilities are subsequently reduced by our payments to lease back the solar power systems, less interest expense calculated based on our incremental borrowing rate adjusted to the rate required to prevent negative amortization. Refer Note 4, Business Divestiture, for details of the sale of our commercial sale-leaseback portfolio during the quarter ended March 31, 2019.

Arrangements with SunPower as a lessor

Solar Services

We offer solar services, in partnership with third-party financial institutions, which allows our residential customers to obtain continuous access to SunPower solar systems under contracts for terms of up to 20 years. Solar services revenue is primarily comprised of revenue from such contracts wherein we provide continuous access to an operating solar system to third parties.

We begin to recognize revenue on solar services when permission to operate ("PTO") is given by the local utility company, system is interconnected and operation commences. We recognize revenue evenly over the time that we satisfy our performance obligations over the initial term of the solar services contracts. Solar services contracts typically have an initial term of 20 years. After the initial contract term, our customers may request an extension of the term of the contract on prevailing market terms, or request to remove the system. Otherwise, the contract will automatically renew and continue on a month-to-month basis.

We also apply for and receive Solar Renewable Energy Credits ("SRECs") associated with the energy generated by our solar energy systems and sell them to third parties in certain jurisdictions. SREC revenue is estimated net of any variable consideration related to possible liquidated damages if we were to deliver fewer SRECs than contractually committed, and is generally recognized upon delivery of the SRECs to the counterparty.

We typically provide a system output performance warranty, separate from our standard solar panel product warranty, to our solar services customers. In connection with system output performance warranties, we agree to pay liquidated damages in the event the system does not perform to the stated specifications, with certain exclusions. The warranty excludes system output shortfalls attributable to force majeure events, customer curtailment, irregular weather, and other similar factors. In the event that the system output falls below the warrantied performance level during the applicable warranty period, and provided that the shortfall is not caused by a factor that is excluded from the performance warranty, the warranty provides that we will pay the customer an amount based on the value of the shortfall of energy produced relative to the applicable warrantied performance level. Such liquidated damages represent a form of variable consideration and are estimated at contract inception and updated at each reporting period and recognized over time as customers receive and consume the benefits of the solar services.

There are rebate programs offered by utilities in various jurisdictions and are issued directly to homeowners and based on the lease agreements, the homeowners assign these rights to rebate to us. These rights to rebate are considered non-cash consideration, measured based on the utilities' rebates from the installed solar panels on the homeowners' roofs and recognized over the lease term.

We capitalize incremental costs incurred to obtain a contract in prepaid and other assets on the condensed consolidated balance sheets. These amounts are amortized on a straight-line basis over the term of the solar services contracts, and are included in cost of revenue in the consolidated statements of operations.

Recently Adopted Accounting Pronouncements

In October 2018, the Financial Accounting Standard Board ("FASB") issued ASU 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes, which permits the use of Overnight Index Swap Rate based on the Secured Overnight Financing Rate as a fifth U.S. benchmark interest rate for purposes of hedge accounting. The new guidance is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years and should be applied prospectively for qualifying new or re-designated hedging relationships entered into after December 31, 2018. We adopted the new guidance on December 31, 2018. The adoption did not have an impact on our consolidated financial statements.

In February 2016, the FASB issued ASC 842, which supersedes the existing guidance for lease accounting, Leases (Topic 840). ASC 842 requires lessees to recognize a lease liability and a ROU asset for virtually all of their leases (other than leases that meet the definition of a short-term lease). ASC 842 is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. In July 2018, the FASB issued several ASUs to clarify and improve certain aspects of the new lease standard including, among many other things, the rate implicit in the lease, lessee reassessment of lease classification, variable payments that depend on an index or rate, methods of transition including an optional transition method to continue recognizing and disclosing leases entered into prior to the adoption date under current GAAP ("ASC 840"). In

Table of Contents

December 2018, the FASB issued ASU 2018-20, Leases (Topic 842) Narrow-Scope Improvements for Lessors, related to sales taxes and other similar taxes collected from lessees, certain lessor costs paid by lessees to third parties, and related to recognition of variable payments for contracts.

On December 31, 2018, we adopted ASC 842 using the optional transitional method for all leases that existed at or commenced before that date. We elected to apply the practical expedients in ASC 842-10-65-1 (f) and (g), and therefore:


1)	did not reassess expired contracts for presence of lease components therein and if it was already concluded that such contracts had lease components then the classification of the respective lease components therein have not been re-assessed;


2)	did not re-assess initial direct costs for any existing leases;


3)	used hindsight for determining the lease term for all leases whereon ASC 842 has been applied;


4)	elected to not separate the lease and non-lease components;


5)	elected to not apply the recognition and measurement requirements of the new guidance to short-term leases;


6)	did not assess whether existing or expired land easements that were not previously assessed under legacy guidance on leases are or contain a lease under the new guidance;

The adoption of ASC 842 had a material impact on our condensed consolidated balance sheet as the standard requires us to recognize an ROU asset and lease liability on our condensed consolidated balance sheet as of December 31, 2018, for all existing leases other than those to which we have applied the short-term lease practical expedient.

Upon adoption, we made the following changes to our accounting policies:

•Solar leases no longer meet the criteria for lease accounting as our contracts do not allow the customer to direct the use of the underlying solar system. Instead, we will now account for these arrangements as contracts with customers pursuant to ASC Topic 606 and recognize revenue ratably based on contractual lease cash flows over the lease term;

•All operating lease arrangements, other than short term leases, are now recorded on the balance sheet as a ROU asset with a corresponding lease liability;

Further, arrangements that involve the lease-back of solar systems sold to a financier will continue to be accounted for as a failed sale and result in the recording of a financing liability.

Topic 326 requires measurement and recognition of expected credit losses for financial assets held. Topic 326 is effective for us no later than the first quarter of fiscal 2020 with early adoption permitted. We are evaluating the potential impact of this ASU on our consolidated financial statements and disclosures.

In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606, which 1) clarifies that certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606; 2) adds unit-of-account guidance in Topic 808 to align with the guidance in Topic 606; and 3) requires that in a transaction with a collaborative arrangement participant that is not directly related to sales to third parties, presenting the transaction together with revenue recognized under Topic 606 is precluded if the collaborative arrangement participant is not a customer. This ASU is effective for us no later than the first quarter of 2020 on a retrospective basis with early adoption permitted. We are evaluating the potential impact of this ASU on our consolidated financial statements and disclosures.

In October 2018, the FASB issued ASU 2018-17, Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities, which broadens the scope of the private company alternative to include all common control arrangements that meet specific criteria (not just leasing arrangements) and also eliminates the requirement that entities consider indirect interests held through related parties under common control in their entirety when assessing whether a decision-making fee is a variable interest. This ASU is effective for us no later than the first quarter of 2020 on a retrospective basis with a cumulative-effect adjustment to retained earnings at the beginning of the earliest period presented. We are evaluating the potential impact of this ASU on our consolidated financial statements and disclosures.

In August 2018, the FASB issued ASU 2018-15, Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40) requiring a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets. This ASU is effective for us no later than the first quarter of 2020 with early adoption permitted. This ASU can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We are evaluating the potential impact of this standard on our consolidated financial statements and disclosures.

In August 2018, the FASB issued ASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20) to add, remove, and clarify disclosure requirements related to defined benefit pension and other postretirement plans. This ASU is effective for us no later than the first quarter of 2020 with early adoption permitted. We are evaluating the potential impact of this standard on our consolidated financial statements and disclosures.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) which changes the fair value measurement disclosure requirements of ASC 820. The guidance adds and clarifies certain disclosure requirements for fair value measurements with the objective of improving the effectiveness of disclosures in the notes to financial statements. This ASU is effective for us no later than the first quarter of 2020 with early adoption permitted. We are evaluating the potential impact of this standard on our consolidated financial statements and disclosures.

Note 2. TRANSACTIONS WITH TOTAL AND TOTAL S.A.

In June 2011, Total completed a cash tender offer to acquire 60% of our then outstanding shares of common stock at a price of $23.25 per share, for a total cost of approximately $1.4 billion. In December 2011, we entered into a Private Placement Agreement with Total (the "Private Placement Agreement"), under which Total purchased, and we issued and sold, 18.6 million shares of our common stock for a purchase price of $8.80 per share, thereby increasing Total's ownership to approximately 66% of our outstanding common stock as of that date. As of March 31, 2019, through the increase of our total outstanding common stock due to the exercise of warrants and issuance of restricted and performance stock units, Total's ownership of our outstanding common stock was approximately 55%.

Supply Agreements

In November 2016, we and Total entered into a four-year, up to 200 megawatts ("MW") supply agreement to support the solarization of certain Total facilities. The agreement covers the supply of 150 MW of Maxeon 2 (formally known as E-Series) panels with an option to purchase up to another 50 MW of P-Series solar panels. In March 2017, we received a prepayment totaling $88.5 million. The prepayment is secured by certain of our assets located in the United States and in Mexico.

We recognize revenue for the solar panels supplied under this arrangement consistent with our revenue recognition policy for solar power components at a point in time when control of such products transfers to the customer, which generally occurs upon shipment or delivery depending on the terms of the contracts. In the second quarter of fiscal 2017, we started to supply Total with solar panels under the supply agreement and as of March 31, 2019, we had $18.6 million of "contract liabilities, current portion" and $41.3 million of "contract liabilities, net of current portion" on our condensed consolidated balance sheets related to the aforementioned supply agreement (see Note 9. Commitments and Contingencies").

In March 2018, we and Total, each through certain affiliates, entered into an agreement whereby we agreed to sell 3.42 MW of photovoltaic ("PV") modules to Total for a development project in Chile. This agreement provided for payment from Total in the amount of approximately $1.3 million, 10% of which was paid upon execution of the agreement.

On January 7, 2019, we and Total, each through certain affiliates, entered into an agreement whereby we agreed to sell 3.7 MW of PV modules to Total for a ground-mounted PV installation in Dubai. This agreement provided for payment from Total in the amount of approximately $1.35 million, 10% of which was received after execution of the agreement.

On March 4, 2019, we and Total, each through certain affiliates, entered into an agreement whereby we agreed to sell 10 MW of PV modules to Total for commercial rooftop PV installations in Dubai. This agreement provided for payment from Total in the amount of approximately $3.16 million, 10% of which is paid in April 2019.

Amended and Restated Credit Support Agreement

In June 2016, we and Total S.A. entered into an Amended and Restated Credit Support Agreement (the "Credit Support Agreement"), which amended and restated the Credit Support Agreement dated April 28, 2011, by and between us and Total S.A., as amended. Under the Credit Support Agreement, Total S.A. agreed to enter into one or more guarantee agreements (each a "Guaranty") with banks providing letter of credit facilities to us. At any time until December 31, 2018, Total S.A. will, at our request, guarantee the payment to the applicable issuing bank of our obligation to reimburse a draw on a letter of credit and pay interest thereon in accordance with the letter of credit facility between such bank and us. Such letters of credit must be issued no later than December 31, 2018 and expire no later than March 31, 2020. Total S.A. is required to issue and enter into a Guaranty requested by us, subject to certain terms and conditions. In addition, Total will not be required to enter into the Guaranty if, after giving effect to our request for a Guaranty, the sum of (a) the aggregate amount available to be drawn under all guaranteed letter of credit facilities, (b) the amount of letters of credit available to be issued under any guaranteed facility, and (c) the aggregate amount of draws (including accrued but unpaid interest) on any letters of credit issued under any guaranteed facility that have not yet been reimbursed by us, would exceed $500.0 million in the aggregate. Such maximum amounts of credit support available to us can be reduced upon the occurrence of specified events.

Table of Contents

In consideration for the commitments of Total S.A. pursuant to the Credit Support Agreement, we are required to pay Total S.A. a guaranty fee for each letter of credit that is the subject of a Guaranty under the Credit Support Agreement and was outstanding for all or part of the preceding calendar quarter. The Credit Support Agreement terminated on December 31, 2018, and we decided not to renew it.

In addition to the Credit Support Agreement, we and Total S.A. entered into the Letter Agreement in May 2017 to facilitate the issuance by Total S.A. of one or more guaranties of our payment obligations of up to $100.0 million (the "Support Amount") under the Revolver; See "Note 11. Debt and Credit Sources" for additional information on the Revolver. In consideration for the commitments of Total S.A. pursuant to the Letter Agreement, we are required to pay a guarantor commitment fee of 0.50% per annum for the unutilized Support Amount and a guaranty fee of 2.35% per annum of the Guaranty outstanding. The maturity date of the Letter Agreement is August 26, 2019.

Affiliation Agreement

We and Total have entered into an Affiliation Agreement that governs the relationship between Total and us (the "Affiliation Agreement"). Until the expiration of a standstill period specified in the Affiliation Agreement (the "Standstill Period"), and subject to certain exceptions, Total, Total S.A., and any of their respective affiliates and certain other related parties (collectively, the "Total Group") may not effect, seek, or enter into discussions with any third party regarding any transaction that would result in the Total Group beneficially owning our shares in excess of certain thresholds, or request us or our independent directors, officers or employees, to amend or waive any of the standstill restrictions applicable to the Total Group. The Standstill Period ends when Total holds less than 15% ownership of us.

The Affiliation Agreement imposes certain limitations on the Total Group's ability to seek to effect a tender offer or merger to acquire 100% of the outstanding voting power of us and imposes certain limitations on the Total Group's ability to transfer 40% or more of the outstanding shares or voting power of us to a single person or group that is not a direct or indirect subsidiary of Total S.A. During the Standstill Period, no member of the Total Group may, among other things, solicit proxies or become a participant in an election contest relating to the election of directors to our Board of Directors.

The Affiliation Agreement provides Total with the right to maintain its percentage ownership in connection with any new securities issued by us, and Total may also purchase shares on the open market or in private transactions with disinterested stockholders, subject in each case to certain restrictions.

The Affiliation Agreement also imposes certain restrictions with respect to the ability of us and our board of directors to take certain actions, including specifying certain actions that require approval by the directors other than the directors appointed by Total and other actions that require stockholder approval by Total.

Research & Collaboration Agreement

We and Total have entered into a Research & Collaboration Agreement (the "R&D Agreement") that establishes a framework under which the parties engage in long-term research and development collaboration ("R&D Collaboration"). The R&D Collaboration encompasses a number of different projects, with a focus on advancing our technology position in the crystalline silicon domain, as well as ensuring our industrial competitiveness. The R&D Agreement enables a joint committee to identify, plan and manage the R&D Collaboration.

Upfront Warrant

In February 2012, we issued a warrant (the "Upfront Warrant") to Total S.A. to purchase 9,531,677 shares of our common stock with an exercise price of $7.8685, subject to adjustment for customary anti-dilution and other events. The Upfront Warrant, which was governed by a Private Placement Agreement and a Compensation and Funding Agreement, dated February 28, 2012, as amended, was exercisable at any time for seven years after its issuance, provided that, so long as at least $25.0 million in aggregate of our convertible debt remains outstanding, such exercise would not cause any "person," including Total S.A., to, directly or indirectly, including through one or more wholly-owned subsidiaries, become the "beneficial owner" (as such terms are defined in Rule 13d-3 and Rule 13d-5 under the Securities Exchange Act of 1934, as amended) (the "Exchange Act"), of more than 74.99% of the voting power of our common stock at such time, a circumstance which would trigger the repurchase or conversion of our existing convertible debt. The Upfront Warrant expired by its terms on February 27, 2019.

0.75% Debentures Due 2018

In May 2013, we issued $300.0 million in principal amount of the 0.75% debentures due 2018. An aggregate principal amount of $200.0 million of the 0.75% debentures due 2018 were acquired by Total. The 0.75% debentures due 2018 were convertible into shares of our common stock at any time based on an initial conversion price equal to $24.95 per share, which provided Total the right to acquire up to 8,017,420 shares of our common stock. The applicable conversion rate could adjust in certain circumstances, including a fundamental change, as described in the indenture governing the 0.75% debentures due 2018. On June 1, 2018, the 0.75% senior convertible debentures due 2018 were redeemed at maturity with proceeds from the Term Credit Agreement (the “Term Credit Agreement”) with Credit Agricole Corporate and Investment Bank (“Credit Agricole”) and as of December 30, 2018 were no longer issued or outstanding. On June 19, 2018, we completed the divestiture of our equity interest in the 8point3 Group, and received, after the payment of fees and expenses, merger proceeds of approximately $359.9 million in cash. Immediately following the transaction, we repaid our loan under the Term Credit Agreement in full with the proceeds of the divestiture, retaining the excess proceeds.

0.875% Debentures Due 2021

In June 2014, we issued $400.0 million in principal amount of our 0.875% senior convertible debentures due 2021 (the "0.875% debentures due 2021"). An aggregate principal amount of $250.0 million of the 0.875% debentures due 2021 were acquired by Total. The 0.875% debentures due 2021 are convertible into shares of our common stock at any time based on an initial conversion price equal to $48.76 per share, which provides Total the right to acquire up to 5,126,775 shares of our common stock. The applicable conversion rate may adjust in certain circumstances, including a fundamental change, as described in the indenture governing the 0.875% debentures due 2021.

4.00% Debentures Due 2023

In December 2015, we issued $425.0 million in principal amount of our 4.00% senior convertible debentures due 2023 (the "4.00% debentures due 2023"). An aggregate principal amount of $100.0 million of the 4.00% debentures due 2023 were acquired by Total. The 4.00% debentures due 2023 are convertible into shares of our common stock at any time based on an initial conversion price equal to $30.53 per share, which provides Total the right to acquire up to 3,275,680 shares of our common stock. The applicable conversion rate may adjust in certain circumstances, including a fundamental change, as described in the indenture governing the 4.00% debentures due 2023.

Joint Solar Projects with Total and its Affiliates

We enter into various EPC and O&M agreements relating to solar projects, including EPC and O&M services agreements relating to projects owned or partially owned by Total and its affiliates. As of March 31, 2019, we had an insignificant amount of "Contract assets" and $5.3 million of "Accounts receivable, net" on our Condensed Consolidated Balance Sheets related to projects in which Total and its affiliates have a direct or indirect material interest.

In connection with a co-development solar project among us, Total, and an independent third party, we sold 25% of our ownership interests in the co-development solar project to Total. The amount received from Total was immaterial in fiscal 2018. We intend to sell an additional 25% of its ownership interest to Total in 2019 and will supply PV in late 2019 to the solar project. However, recent amendments to the feed-in-tariff rules in Japan have had a significant impact on the co-development solar project’s ability to secure financing and we are currently exploring alternatives to monetize our investment in the co-development solar project.

In connection with a co-development solar project between us and Total, we paid $0.5 million to Total for development fees for the three months ended April 1, 2018.

We recognize revenue for sales of modules and components at the point that control transfers to the customer, which typically occurs upon shipment or delivery to the customer, depending on the terms of the contract, and we recognize revenue for operations and maintenance and solar services over the term of the service period.

Table of Contents

For engineering, procurement and construction ("EPC") revenue and solar power systems sales, we commence recognizing revenue when control of the underlying system transfers to the customer and continue recognizing revenue over time as work is performed based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligations.

Judgment is required to evaluate assumptions including the amount of net contract revenues and the total estimated costs to determine our progress towards contract completion and to calculate the corresponding amount of revenue to recognize. If estimated total costs on any contract are greater than the net contract revenues, we recognize the entire estimated loss in the period the loss becomes known. For contracts with post-installation systems monitoring and maintenance, we recognize revenue related to systems monitoring and maintenance over the non-cancellable contract term on a straight-line basis.

Changes in estimates for sales of systems and EPC services occur for a variety of reasons, including but not limited to (i) construction plan accelerations or delays, (ii) product cost forecast changes, (iii) change orders, or (iv) changes in other information used to estimate costs. Changes in estimates may have a material effect in our condensed consolidated statements of operations. The table below outlines the impact on revenue of net changes in estimated transaction prices and input costs for systems related sales contracts (both increases and decreases) for the three months ended March 31, 2019 and April 1, 2018 as well as the number of projects that comprise such changes. For purposes of the following table, only projects with changes in estimates that have an impact on revenue and or cost of at least $1.0 million during the periods were presented. Also included in the table is the net change in estimate as a percentage of the aggregate revenue for such projects.

Contract Assets and Liabilities

Contract assets consist of (i) retainage which represents the earned, but unbilled, portion of a construction and development project for which payment is deferred by the customer until certain contractual milestones are met; and (ii) unbilled receivables which represent revenue that has been recognized in advance of billing the customer, which is common for long-term construction contracts. Contract liabilities consist of deferred revenue and customer advances, which represent consideration received from a customer prior to transferring control of goods or services to the customer under the terms of a sales contract. Refer to "Note 5. Balance Sheet Components" for further details.

During the three months ended March 31, 2019, the decrease in contract assets of $1.7 million was primarily driven by billings for commercial projects where certain milestones had been reached. During the three months ended March 31, 2019, the decrease in contract liabilities of $36.0 million was primarily due to utilization of customer advances, reclassification of contract liabilities related to sale-leaseback arrangements to lease liabilities, and adjustment for a portion of deferred profit on sale-leaseback arrangements to retained earnings, upon adoption of ASC 842. During the three months ended March 31, 2019, we recognized revenue of $26.3 million that was included in contract liabilities as of December 30, 2018.

Table of Contents

The following table represents our remaining performance obligations as of March 31, 2019 for our sales of solar power systems, including projects under sales contracts subject to conditions precedent, and EPC agreements for developed projects that we are constructing or expect to construct. We expect to recognize $94.8 million of revenue for such contracts upon transfer of control of the projects.

¹Denotes average percentage of revenue recognized.

As of March 31, 2019, we entered into contracts with customers for the future sale of modules and components for an aggregate transaction price of $453.7 million, the substantial majority of which we expect to recognize as revenue through the second and third quarter of fiscal 2019. As of March 31, 2019, we had entered into O&M contracts of utility-scale PV solar power systems. We expect to recognize $125.3 million of revenue over the service period for solar services contracts entered into as of three months ended March 31, 2019. We expect to recognize $10.2 million of revenue during the non-cancellable term of these O&M contracts over an average period of three months.

Note 4. BUSINESS DIVESTITURE

Sale of Commercial Sale-Leaseback Portfolio

We entered into sale-leaseback arrangements under which solar power systems were sold to third parties and subsequently leased back by us over lease terms of up to 25 years. Separately, we entered into sales of energy under power purchase agreements ("PPAs") with end customers, who host the leased solar power systems and buy the electricity directly from us under PPAs with terms of up to 25 years. At the end of the lease term, we have the option to purchase the systems at fair value or may be required to remove the systems and return them to the third parties.

On March 26, 2019, we entered into a Membership Interest Purchase and Sale Agreement (the “Purchase and Sale Agreement”) with a wholly-owned subsidiary of Goldman Sachs Renewable Power LLC. Pursuant to the Purchase and Sale Agreement, we agreed to sell, in exchange for cash consideration of up to $86.9 million, membership interests in certain of our holding company subsidiaries (the “Holdco” or “Holdcos”) that directly or indirectly own leasehold interests in operating solar photovoltaic electric generating projects (the “Projects”) subject to sale-leaseback financing arrangements with one or more financiers (each a "Lessor") and other related subsidiaries. The Projects are located at approximately 200 sites across the United States, and represent in aggregate, approximately 233 MW of generating capacity. The portfolio of Projects financed by each lessor represents a separate asset (“Portfolio”) for which the price is separately agreed and stated in the Purchase and Sale Agreement.

The consummation of the sale and purchase of each Portfolio is subject to a number of customary conditions precedent, including receipt of certain third-party consents and approvals, including those of the applicable Lessor. The completion of sale of each Portfolio will happen as the underlying conditions precedent are satisfied.

On March 29, 2019, we completed the sale of one such Portfolio in exchange for total consideration of $7.6 million in cash. We also retained a favorable O&M contract given current market pricing, which we recorded at fair value as an other intangible asset. In evaluating the accounting treatment for this transaction, we concluded that the Portfolio meets the definition of a business. In connection with the sale transaction, we recognized a gain of $6.1 million, which is included within "gain on business divestiture" in our condensed consolidated statements of operations for the three months ended March 31, 2019. We have also incurred approximately $0.4 million of transaction costs related to the above transactions to date, which were expensed as incurred.

Assets Held for Sale

Upon execution of the Purchase and Sale Agreement, the assets and liabilities within the remaining portfolio subject to sale meet the criteria for classification as held for sale ("HFS"), since the assets are subject only to usual and customary closing conditions, and the sale is expected to be completed in less than one year from the date of the Agreement. All assets and liabilities within the portfolios for which the sale is not completed as of March 31, 2019 have accordingly been classified as HFS on the condensed consolidated balance sheet. The following table represents assets and liabilities HFS as of March 31, 2019.

Impairment of Residential Lease Assets

On November 5, 2018, we sold 49% of our membership interest in SunStrong Capital Holdings LLC (“SunStrong”), formerly our wholly owned subsidiary that historically held and controlled the assets and liabilities comprising our residential lease business. Following the closing, we deconsolidated certain entities involved in our residential lease portfolio and retained membership units representing a 51% membership interest in SunStrong. We continue to retain certain residential assets subject to leasing arrangements on our condensed consolidated balance sheet as of March 31, 2019, which we expect to sell in fiscal 2019, and these assets have been tested for impairment as described below.

We evaluate our long-lived assets, including property, plant and equipment, solar power systems leased and to be leased, and other intangible assets with finite lives, for impairment whenever events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. Factors considered important that could result in an impairment review include significant under-performance relative to expected historical or projected future operating results, significant changes in the manner of use of acquired assets, and significant negative industry or economic trends. Our impairment evaluation of long-lived assets includes an analysis of estimated future undiscounted net cash flows expected to be generated by the assets over their remaining estimated useful lives. If our estimate of future undiscounted net cash flows is insufficient to recover the carrying value of the assets over the remaining estimated useful lives, it records an impairment loss in the amount by which the carrying value of the assets exceeds the fair value. Fair value is generally measured based on either quoted market prices, if available, or discounted cash flow analysis.

Financing receivables are generated by solar power systems leased to residential customers under sales-type leases. Financing receivables represent gross minimum lease payments to be received from customers over a period commensurate with the remaining lease term and the system's estimated residual value, net of unearned income and allowance for estimated losses. Our evaluation of the recoverability of these financing receivables is based on evaluation of the likelihood, based on current information and events, and whether we will be able to collect all amounts due according to the contractual terms of the underlying lease agreements. In accordance with this evaluation, we recognize an allowance for losses on financing receivables based on our estimate of the amount equal to the probable losses net of recoveries. The combination of the leased solar power

Table of Contents

systems discussed in the preceding paragraph together with the lease financing receivables is referred to as the "Residential Lease Portfolio."

We performed a recoverability test for assets in the Residential Lease Portfolio by estimating future undiscounted net cash flows expected to be generated by the assets, based on our own specific alternative courses of action under consideration. The alternative courses were either to sell or refinance the assets, or hold the assets until the end of their previously estimated useful lives. Upon consideration of the alternatives, we determined that market value, in the form of indicative purchase price from a third-party investor was available for a portion of our Residential Lease Portfolio, represented by net assets related to projects financed by a tax equity investor. As we intend to sell these assets in fiscal 2019, we used the indicative purchase price from a third-party investor as fair value of the underlying net assets in our impairment evaluation.

In accordance with the impairment evaluation, we recognized a non-cash impairment charge of $9.2 million included in "impairment of residential lease assets" on the condensed consolidated statement of operations for the three months ended March 31, 2019. Due to the fact that the Residential Lease Portfolio assets are held in a partnership flip structure with noncontrolling interests, we allocated a portion of the impairment charge related to such noncontrolling interests through the hypothetical liquidation at book value ("HLBV") method. The allocation method applied to the noncontrolling interests and redeemable noncontrolling interests resulted in a net gain of $0.8 million and an immaterial amount for the three months ended March 31, 2019 and April 1, 2018, respectively. As a result, the net impairment charges attributable to our stockholders totaled $8.4 million and $49.0 million for the three months ended March 31, 2019 and April 1, 2018, respectively, and were recorded within the SunPower Energy Services Segment.

The impairment evaluation requires us to make assumptions and to apply judgment to estimate future cash flows and assumptions. If actual results are not consistent with our estimates and assumptions used in estimating future cash flows and asset fair values, and if and when a divestiture transaction occurs, the details and timing of which are subject to change as the final terms are negotiated between us and the intended purchaser, we may be exposed to additional impairment charges in the future, which could be material to the results of operations.

Note 7. FAIR VALUE MEASUREMENTS

Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement (observable inputs are the preferred basis of valuation):


•	Level 1 — Quoted prices in active markets for identical assets or liabilities.


•	Level 2 — Measurements are inputs that are observable for assets or liabilities, either directly or indirectly, other than quoted prices included within Level 1.


•	Level 3 — Prices or valuations that require management inputs that are both significant to the fair value measurement and unobservable.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

We measure certain assets and liabilities at fair value on a recurring basis. There were no transfers between fair value measurement levels during any presented period.

The following table summarizes our assets and liabilities measured and recorded at fair value on a recurring basis as of March 31, 2019 and December 30, 2018:

We have elected the fair value option ("FVO") in accordance with the guidance in ASC 825, for our investment in SunStrong joint venture, to mitigate volatility in reported earnings that results from the use of different measurement attributes. We initially computed the fair value for our investment consistent with the methodology and assumptions that market participants would use in their estimates of fair value with the assistance of a third-party valuation specialist. The fair value computation is updated on a quarterly basis. The investment is classified within Level 3 in the fair value hierarchy because we estimate the fair value of the investment using the income approach based on the discounted cash flow method which considered estimated future financial performance, including assumptions for, among others, forecasted contractual lease income, lease expenses, residual value of these lease assets and long-term discount rates, and forecasted default rates over the lease term and discount rates, some of which require significant judgment by management and are not based on observable inputs.

Other financial assets and liabilities, including our accounts receivable, accounts payable and accrued liabilities, are carried at cost, which generally approximates fair value due to the short-term nature of these financial assets and liabilities.

Table of Contents

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

We measure certain investments and non-financial assets (including property, plant and equipment, and other intangible assets) at fair value on a non-recurring basis in periods after initial measurement in circumstances when the fair value of such asset is impaired below its recorded cost. As of March 31, 2019 and December 30, 2018, there were no such items recorded at fair value, with the exception of our residential lease assets (see "Note 6. Solar Services").

Held-to-Maturity Debt Securities

Our debt securities, classified as held-to-maturity, are Philippine government bonds that we maintain as collateral for business transactions within the Philippines. These bonds have various maturity dates and are classified as "Restricted long-term marketable securities" on our condensed consolidated balance sheets. As of March 31, 2019 and December 30, 2018, these bonds had a carrying value of $5.9 million and $6.0 million, respectively. We record such held-to-maturity investments at amortized cost based on our ability and intent to hold the securities until maturity. We monitor for changes in circumstances and events that would affect our ability and intent to hold such securities until the recorded amortized costs are recovered. No other-than-temporary impairment loss was incurred during any periods presented. The held-to-maturity debt securities were categorized in Level 2 of the fair value hierarchy.

Equity Investments

The following discusses our marketable equity investments, non-marketable equity investments and equity method investments. See Note 10. Equity Investments.

Marketable Equity Investments

In connection with the divestment of our microinverter business to Enphase on August 9, 2018, we received 7.5 million shares of Enphase common stock (NASDAQ: ENPH). The common stock received was recorded as an equity investment with readily determinable fair value (Level 1), with changes in fair value recognized in net income in accordance with ASU 2016-01. For the three months ended March 31, 2019, we recorded a $33.0 million unrealized gain within "other, net" in our condensed consolidated statement of operations.

Non-Marketable Equity Investments

Our non-marketable equity investments are securities in privately-held companies without readily determinable market values. Prior to January 1, 2018, we accounted for the non-marketable equity investments at cost less impairment. On January 1, 2018, we adopted ASU 2016-01 and elected to adjust the carrying value of our non-marketable equity securities to cost less impairment, adjusted for observable price changes in orderly transactions for an identical or similar investment of the same issuer. Non-marketable equity securities are classified within Level 3 in the fair value hierarchy because we estimate the value based on valuation methods using a combination of observable and unobservable inputs including valuation ascribed to the issuing company in subsequent financing rounds, volatility in the results of operations of the issuers and rights and obligations of the securities we hold. As of both March 31, 2019 and December 30, 2018, we had $8.8 million in investments accounted for under the measurement alternative method.

Equity Method Investments

Our investments accounted for under the equity method are described in Note 10. Equity Investments. We monitor these investments, which are included within "other long-term assets" on our condensed consolidated balance sheets, for impairment and record reductions in the carrying values when necessary. Circumstances that indicate an other-than-temporary decline include Level 3 measurements such as the valuation ascribed to the issuing company in subsequent financing rounds, decreases in quoted market prices, and declines in the results of operations of the issuer.

As of March 31, 2019 and December 30, 2018, we had $36.3 million and $34.8 million, respectively, in investments accounted for under the equity method (see "Note 10. Equity Investments").

Note 8. RESTRUCTURING

February 2018 Restructuring Plan

During the first quarter of fiscal 2018, we adopted a restructuring plan and began implementing initiatives to reduce operating expenses and cost of revenue overhead in light of the known shorter-term impact of U.S. tariffs imposed on PV solar cells and modules pursuant to Section 201 of the Trade Act of 1974 and our broader initiatives to control costs and improve cash flow. In connection with the plan, which is expected to be completed by mid-2019, we expect between 150 and 250 non-manufacturing employees to be affected, representing approximately 3% of our global workforce, with a portion of those employees exiting from us as part of a voluntary departure program. The changes to our workforce will vary by country, based on local legal requirements and consultations with employee works councils and other employee representatives, as appropriate. We expect to incur restructuring charges totaling between $20 million to $30 million, consisting primarily of severance benefits (between $11 million and $16 million) and real estate lease termination and other associated costs (between $9 million and $14 million). We expect between $12 million and $20 million of the charges to be paid in cash. The actual timing and costs of the plan may differ from our current expectations and estimates. A substantial portion of such charges were incurred in fiscal 2018. Cumulative costs incurred were $11.8 million as of March 31, 2019.

Legacy Restructuring Plans

Prior to fiscal 2018, we implemented approved restructuring plans, related to all segments, to reduce costs and focus on improving cash flow, to realign our legacy power plant business unit, to align with changes in the global solar market, as well as actions to accelerate operating cost reduction and improve overall operating efficiency. These restructuring activities were substantially complete as of December 30, 2018, and any remaining costs to be incurred are not expected to be material. Cumulative costs incurred were $376.7 million as of March 31, 2019.

The following table summarizes the comparative periods-to-date restructuring charges by plan recognized in our condensed consolidated statements of operations:

Note 9. COMMITMENTS AND CONTINGENCIES

Facility and Equipment Leases

We lease certain facilities under non-cancellable operating leases from third parties. We also lease certain buildings under non-cancellable capital leases. Operating leases are subject to renewal options for periods ranging from 1 year to 10 years.

We have disclosed quantitative information related to the lease contracts we have entered into as a lessee by aggregating the information based on the nature of asset such that the assets of similar characteristics and lease terms are shown within one single financial statement line item.

The table below presents the summarized quantitative information with regard to lease contracts we have entered into:

As of March 31, 2019, we have additional operating leases that have not yet commenced with future minimum lease payments amounting to $36.7 million. These operating leases will commence in the third quarter of fiscal 2019 with lease terms ranging from 1 year to 19 years.

Purchase Commitments

We purchase raw materials for inventory and manufacturing equipment from a variety of vendors. During the normal course of business, in order to manage manufacturing lead times and help assure adequate supply, we enter into agreements with contract manufacturers and suppliers that either allow them to procure goods and services based on specifications defined by us, or that establish parameters defining our requirements. In certain instances, these agreements allow us the option to cancel, reschedule or adjust our requirements based on our business needs before firm orders are placed. Consequently, purchase commitments arising from these agreements are excluded from our disclosed future obligations under non-cancellable and unconditional commitments.

We also have agreements with several suppliers, including some of our non-consolidated investees, for the procurement of polysilicon, ingots, and wafers, as well as certain module-level power electronics and related equipment, which specify future quantities and pricing of products to be supplied by three vendors for periods of up to 2 years and provide for certain consequences, such as forfeiture of advanced deposits and liquidated damages relating to previous purchases, in the event that we terminate the arrangements or fail to satisfy our obligations under the agreements.

Future purchase obligations under non-cancellable purchase orders and long-term supply agreements as of March 31, 2019 are as follows:



(In thousands)	Fiscal 2019 (remaining nine months)		Fiscal 2020		Fiscal 2021		Fiscal 2022		Fiscal 2023		Thereafter		Total¹
Future purchase obligations	$	309,322	$	374,930	$	38,650	$	35,425	$	32,550	$	—	$	790,877

¹Total future purchase obligations were composed of $182.8 million related to non-cancellable purchase orders and $608.1 million related to long-term supply agreements.

We expect that all obligations related to non-cancellable purchase orders for manufacturing equipment will be recovered through future cash flows of the solar cell manufacturing lines and solar panel assembly lines when such long-lived assets are placed in service. Factors considered important that could result in an impairment review include significant under-performance relative to expected historical or projected future operating results, significant changes in the manner of use of acquired assets, and significant negative industry or economic trends. Obligations related to non-cancellable purchase orders for inventories match current and forecasted sales orders that will consume these ordered materials and actual consumption of these ordered materials is regularly compared to expected demand. We anticipate total obligations related to long-term supply agreements for inventories, some of which (in the case of polysilicon) are at purchase prices significantly above current market prices for similar materials, will be recovered because the quantities required to be purchased are expected to be utilized in the manufacture and profitable sale of solar power products in the future based on our long-term operating plans. Additionally, in order to reduce inventory and improve working capital, we have periodically elected to sell polysilicon inventory in the marketplace at prices below our purchase price, thereby incurring a loss. The terms of the long-term supply agreements are reviewed annually by us and we assess the need for any accruals for estimated losses on adverse purchase commitments, such

Table of Contents

as lower of cost or net realizable value adjustments that will not be recovered by future sales prices, forfeiture of advanced deposits and liquidated damages, as necessary.

Advances to Suppliers

As noted above, we have entered into agreements with various vendors, some of which are structured as "take or pay" contracts, that specify future quantities and pricing of products to be supplied. Certain agreements also provide for penalties or forfeiture of advanced deposits in the event we terminate the arrangements. Under certain agreements, we were required to make prepayments to the vendors over the terms of the arrangements. As of March 31, 2019 and December 30, 2018, advances to suppliers totaled $158.5 million and $171.6 million, respectively, of which $95.6 million and $37.9 million, respectively, is classified as Advances to suppliers, current portion on our condensed consolidated balance sheets. One supplier accounted for 99.9% and 99.6% of total advances to suppliers as of March 31, 2019 and December 30, 2018, respectively.

Advances from Customers

The estimated utilization of advances from customers included within "Contract liabilities, current portion" and "Contract liabilities, net of current portion" on our condensed consolidated balance sheets as of March 31, 2019 is as follows:



(In thousands)	Fiscal 2019 (remaining nine months)		Fiscal 2020		Fiscal 2021		Fiscal 2022		Fiscal 2023		Thereafter		Total
Estimated utilization of advances from customers	$	57,032	$	15,352	$	29,773	$	—	$	—	$	—	$	102,157

We have entered into other agreements with customers who have made advance payments for solar power products and systems. These advances will be applied as shipments of product occur or upon completion of certain project milestones. In November 2016, we and Total entered into a four-year, up to 200-MW supply agreement to support the solarization of Total facilities (see "Note 2. Transactions with Total and Total S.A."); in March 2017, we received a prepayment totaling $88.5 million. As of March 31, 2019, the advance payment from Total was $59.9 million, of which $18.6 million was classified as short-term on our condensed consolidated balance sheets, based on projected shipment dates.

Product Warranties

The following table summarizes accrued warranty activities for the three months ended March 31, 2019 and April 1, 2018:



	Three Months Ended
(In thousands)	March 31, 2019			April 1, 2018
Balance at the beginning of the period	$	172,266		$	181,303
Accruals for warranties issued during the period	4,621			3,838
Settlements and adjustments during the period	(13,683		)	(5,972		)
Balance at the end of the period	$	163,204		$	179,169

In some cases, we may offer customers the option to purchase extended warranties to ensure protection beyond the standard warranty period. In those circumstances, the warranty is a distinct service and we account for the extended warranty as a performance obligation and allocates a portion of the transaction price to that performance obligation. More frequently, customers do not purchase a warranty separately. In those situations, we account for the warranty as an assurance-type warranty, which provides customers with assurance that the product complies with agreed-upon specifications, and this does not represent a separate performance obligation.

Table of Contents

Project Agreements with Customers

Project agreements entered into with our commercial and power plant customers often require us to undertake obligations including: (i) system output performance warranties, (ii) penalty payments or customer termination rights if the system we are constructing is not commissioned within specified time frames or other milestones are not achieved, and (iii) system put-rights whereby we could be required to buy back a customer's system at fair value on specified future dates if certain minimum performance thresholds are not met for specified periods. Historically, our systems have performed significantly above their performance warranty thresholds, and there have been no cases in which we have had to buy back a system. As of March 31, 2019 and December 30, 2018, we had $4.3 million and $3.3 million, respectively, classified as "accrued liabilities," and $6.9 million and $6.5 million, respectively, classified as "other long-term liabilities" on our condensed consolidated balance sheets for such obligations.

Future Financing Commitments

We are required to provide certain funding under agreements with unconsolidated investees, subject to certain conditions (see "Note 10. Equity Investments"). As of March 31, 2019, we have future financing obligations related to these agreements as follows:



(In thousands)	Amount
Year:
2019 (remaining nine months)	$	940
2020	2,900
	$	3,840

Liabilities Associated with Uncertain Tax Positions

Total liabilities associated with uncertain tax positions were $17.8 million and $16.8 million as of March 31, 2019 and December 30, 2018, respectively. These amounts are included within "other long-term liabilities" on our condensed consolidated balance sheets in their respective periods as they are not expected to be paid within the next 12 months. Due to the complexity and uncertainty associated with our tax positions, we cannot make a reasonably reliable estimate of the period in which cash settlement, if any, would be made for our liabilities associated with uncertain tax positions in Other long-term liabilities.

Indemnifications

We are a party to a variety of agreements under which we may be obligated to indemnify the counterparty with respect to certain matters. Typically, these obligations arise in connection with contracts and license agreements or the sale of assets, under which we customarily agree to hold the other party harmless against losses arising from a breach of warranties, representations and covenants related to such matters as title to assets sold, negligent acts, damage to property, validity of certain intellectual property rights, non-infringement of third-party rights, and certain tax related matters including indemnification to customers under Section 48(c) of the Internal Revenue Code of 1986, as amended, regarding solar commercial investment tax credits ("ITCs") and U.S. Treasury Department ("U.S. Treasury") cash grant payments under Section 1603 of the American Recovery and Reinvestment Act (each a "Cash Grant"). In each of these circumstances, payment by us is typically subject to the other party making a claim to us that is contemplated by and valid under the indemnification provisions of the particular contract, which provisions are typically contract-specific, as well as bringing the claim under the procedures specified in the particular contract. These procedures usually allow us to challenge the other party's claims or, in case of breach of intellectual property representations or covenants, to control the defense or settlement of any third-party claims brought against the other party. Further, our obligations under these agreements may be limited in terms of activity (typically to replace or correct the products or terminate the agreement with a refund to the other party), duration or amount. In some instances, we may have recourse against third parties or insurance covering certain payments made by us.

In certain circumstances, we have provided indemnification to customers and investors under which we are contractually obligated to compensate these parties for losses they may suffer as a result of reductions in benefits received under ITCs and U.S. Treasury Cash Grant programs. We apply for ITCs and Cash Grant incentives based on guidance provided by the Internal Revenue Service ("IRS") and the U.S. Treasury, which include assumptions regarding the fair value of the qualified solar power systems, among others. Certain of our development agreements, sale-leaseback arrangements, and financing arrangements with tax equity investors, incorporate assumptions regarding the future level of incentives to be received, which in some instances

Table of Contents

may be claimed directly by our customers and investors. Generally, such obligations would arise as a result of reductions to the value of the underlying solar power systems as assessed by the IRS. At each balance sheet date, we assess and recognize, when applicable, the potential exposure from these obligations based on all the information available at that time, including any audits undertaken by the IRS. The maximum potential future payments that we could have to make under this obligation would depend on the difference between the eligible basis claimed on the tax filing for the solar energy systems sold or transferred to indemnified parties and the values that the IRS may re-determine as the eligible basis for the systems for purposes of claiming ITCs or Cash Grants. We use the eligible basis for tax filing purposes determined with the assistance of independent third-party appraisals to determine the ITCs that are passed-through to and claimed by the indemnified parties. For sales contracts that have such indemnification provisions, we recognize a liability under ASC 460, "Guarantees," for the estimated premium that would be required by a guarantor to issue the same guarantee in a standalone arm’s-length transaction with an unrelated party. We recognize such liabilities at the greater of the fair value of the indemnity or the contingent liability required to be recognized under ASC 450, "Contingencies," and reduce the revenue recognized in the related transaction. We initially estimate the fair value of any such indemnities provided based on the cost of insurance policies that cover the underlying risks being indemnified and may purchase such policies to mitigate our exposure to potential indemnification payments. After an indemnification liability is recorded, we derecognize such amount typically upon expiration or settlement of the arrangement. Changes to any such indemnification liabilities provided are recorded as adjustments to revenue.

As of March 31, 2019, and December 30, 2018, our provision was $4.5 million and $4.2 million, respectively, primarily for tax related indemnifications.

Defined Benefit Pension Plans

We maintain defined benefit pension plans for certain of our non-U.S. employees. Benefits under these plans are generally based on an employee’s years of service and compensation. Funding requirements are determined on an individual country and plan basis and are subject to local country practices and market circumstances. The funded status of the pension plans, which represents the difference between the benefit obligation and fair value of plan assets, is calculated on a plan-by-plan basis. The benefit obligation and related funded status are determined using assumptions as of the end of each fiscal year. We recognize the overfunded or underfunded status of our pension plans as an asset or liability on our condensed consolidated balance sheets. As of both March 31, 2019 and December 30, 2018, the underfunded status of our pension plans presented within "other long-term liabilities" on our condensed consolidated balance sheets was $2.6 million. The impact of transition assets and obligations and actuarial gains and losses are recorded within "accumulated other comprehensive loss" and are generally amortized as a component of net periodic cost over the average remaining service period of participating employees. Total other comprehensive loss related to our benefit plans was zero for the three months ended March 31, 2019 and April 1, 2018.

Legal Matters

We are a party to various litigation matters and claims that arise from time to time in the ordinary course of our business. While we believe that the ultimate outcome of such matters will not have a material adverse effect on us, their outcomes are not determinable and negative outcomes may adversely affect our financial position, liquidity, or results of operations.

Note 10. EQUITY INVESTMENTS

Our equity investments consist of equity method investments, equity investments with readily determinable fair value and equity investments without readily determinable fair value.

4.00% Debentures Due 2023

In December 2015, we issued $425.0 million in principal amount of our 4.00% debentures due 2023. Interest is payable semi-annually, beginning on July 15, 2016. Holders may exercise their right to convert the debentures at any time into shares of our common stock at an initial conversion price approximately equal to $30.53 per share, subject to adjustment in certain circumstances. If not earlier repurchased or converted, the 4.00% debentures due 2023 mature on January 15, 2023.

0.875% Debentures Due 2021

In June 2014, we issued $400.0 million in principal amount of our 0.875% debentures due 2021. Interest is payable semi-annually, beginning on December 1, 2014. Holders may exercise their right to convert the debentures at any time into shares of our common stock at an initial conversion price approximately equal to $48.76 per share, subject to adjustment in certain circumstances. If not earlier repurchased or converted, the 0.875% debentures due 2021 mature on June 1, 2021.

Other Debt and Credit Sources

Loan Agreement with California Enterprise Development Authority ("CEDA")

In 2010, we borrowed the proceeds of the $30.0 million aggregate principal amount of CEDA's tax-exempt Recovery Zone Facility Revenue Bonds (SunPower Corporation - Headquarters Project) Series 2010 (the "Bonds") maturing April 1, 2031 under a loan agreement with CEDA. The Bonds mature on April 1, 2031, bear interest at a fixed rate of 8.50% through maturity, and include customary covenants and other restrictions on us. As of March 31, 2019, the fair value of the Bonds was $32.4 million, determined by using Level 2 inputs based on quarterly market prices as reported by an independent pricing source.

Revolving Credit Facility with Credit Agricole

On June 23, 2017, we entered into an Amended and Restated Revolving Credit Agreement (the “Revolver”) with Credit Agricole, as administrative agent, and the other lenders party thereto, which amends and restates the Revolving Credit Agreement dated July 3, 2013, as amended.

The Revolver was entered into in connection with the Letter Agreement, to facilitate the issuance by Total S.A. of one or more guaranties of our payment obligations of up to $100.0 million under the Revolver. The maturity date of the Letter Agreement and the Revolver is August 26, 2019. In consideration for the commitments of Total S.A. pursuant to the Letter Agreement, we are required to pay a guarantor commitment fee of 0.50% per annum for the unutilized support amount and a guaranty fee of 2.35% per annum of the Guaranty outstanding. Available borrowings under the Revolver are $300.0 million; provided that the aggregate principal amount of all amounts borrowed under the facility cannot exceed 95.0% of the amounts guaranteed by Total under the Letter Agreement.

reserves required to be maintained against “Eurocurrency liabilities” as specified in Regulation D; and (ii) with respect to any alternate base rate loan, an amount equal to 0.25% plus the greater of (1) the prime rate, (2) the Federal Funds rate plus 0.50%, and (3) the one-month LIBOR rate plus 1%; and (b) a commitment fee of 0.06% per annum on funds available for borrowing and not borrowed. The Revolver includes representations, covenants, and events of default customary for financing transactions of this type. As of both March 31, 2019 and December 30, 2018, we had no outstanding borrowings under the Revolver.

September 2011 Letter of Credit Facility with Deutsche Bank and Deutsche Bank Trust Company Americas (together, "Deutsche Bank Trust")

In September 2011, we entered into a letter of credit facility with Deutsche Bank Trust which provides for the issuance, upon our request, of letters of credit to support our obligations in an aggregate amount not to exceed $200.0 million. Each letter of credit issued under the facility is fully cash-collateralized and we have entered into a security agreement with Deutsche Bank Trust, granting them a security interest in a cash collateral account established for this purpose.

As of March 31, 2019 and December 30, 2018, letters of credit issued and outstanding under the Deutsche Bank Trust facility totaled $2.6 million and $3.0 million, respectively, which were fully collateralized with restricted cash on the condensed consolidated balance sheets.

Other Facilities

Asset-Backed Loan with Bank of America

On March 29, 2019, we entered in a Loan and Security Agreement with Bank of America, N.A, which provides a revolving credit facility secured by certain inventory and accounts receivable in the maximum aggregate principal amount of $50.0 million. The Loan and Security Agreement contains negative and affirmative covenants including maintaining $5.0 million of cash in a designated account, events of default and repayment and prepayment provisions customarily applicable to asset-backed credit facilities. The facility bears a floating interest rate of LIBOR plus an applicable margin, and matures on the earlier of March 29, 2022, a date that is 91 days prior to the maturity of our 2021 convertible debentures, or the termination of the commitments thereunder. As of March 31, 2019, we had drawn $9.0 million under this facility.

SunTrust Facility

On June 28, 2018, we entered in a Financing Agreement with SunTrust Bank, which provides a revolving credit facility in the maximum aggregate principal amount of $75.0 million. Each draw down from the facility bears either a base rate of federal funds rate plus an applicable margin or a floating interest rate of LIBOR plus an applicable margin, and matures no later than three years. As of March 31, 2019, we had $75.0 million in borrowing capacity under this limited recourse construction financing facility.

Non-recourse Financing and Other Debt

In order to facilitate the construction, sale or ongoing operation of certain solar projects, including our residential leasing program, we regularly obtain project-level financing. These financings are secured either by the assets of the specific project being financed or by our equity in the relevant project entity and the lenders do not have recourse to our general assets for repayment of such debt obligations, and hence the financings are referred to as non-recourse. Non-recourse financing is typically in the form of loans from third-party financial institutions, but also takes other forms, including partnership flip structures, sale-leaseback arrangements, or other forms commonly used in the solar or similar industries. We may seek non-recourse financing covering solely the construction period of the solar project or may also seek financing covering part or all of the operating life of the solar project. We classify non-recourse financings on our condensed consolidated balance sheets in accordance with their terms; however, in certain circumstances, we may repay or refinance these financings prior to stated maturity dates in connection with the sale of the related project or similar such circumstances. In addition, in certain instances, the customer may assume the loans at the time that the project entity is sold to the customer. In these instances, subsequent debt assumption is reflected as a financing outflow and operating inflow on our condensed consolidated statements of cash flows to reflect the substance of the assumption as a facilitation of customer financing from a third party.

Foreign Currency Exchange Risk

Designated Derivatives Hedging Cash Flow Exposure

Our cash flow exposure primarily relates to anticipated third-party foreign currency revenues and expenses and interest rate fluctuations. We derive a portion of our revenues in foreign currencies, predominantly in Euro, as part of our ongoing business operations. In addition, a portion of our assets are held in foreign currencies. We enter into foreign currency forward and option contracts designated as cash flow hedges to hedge certain forecasted revenue transactions denominated in currencies other than our functional currency. In the first quarter of fiscal 2019, we entered into foreign currency option contracts to manage volatility related to transactions that are denominated in Euros. We plan to continue entering into these contracts on a quarterly basis. Our foreign currency forward and option contracts are entered into for periods consistent with the related underlying exposures and do not constitute positions that are independent of those exposures.

As of March 31, 2019 and December 30, 2018, we had designated outstanding cash flow hedge forward contracts with a notional value of $44.9 million and zero, respectively. As of March 31, 2019, we also had designated outstanding cash flow hedge option contracts with a notional value of $101.5 million. We designate either gross external or intercompany revenue up to our net economic exposure. These derivatives have a maturity of three months or less and consist of foreign currency forward and option contracts. The effective portion of these cash flow hedges is reclassified into revenue when third-party revenue is recognized in our condensed consolidated statements of operations.

Non-Designated Derivatives Hedging Transaction Exposure

Derivatives not designated as hedging instruments consist of forward and option contracts used to hedge re-measurement of foreign currency denominated monetary assets and liabilities primarily for intercompany transactions, receivables from customers, and payables to third parties. Changes in exchange rates between our subsidiaries' functional currencies and the currencies in which these assets and liabilities are denominated can create fluctuations in our reported condensed consolidated financial position, results of operations and cash flows. As of March 31, 2019, to hedge balance sheet exposure, we held forward contracts with an aggregate notional value of $17.4 million. These contracts have maturity of three months or less and consist of foreign currency forward contracts. As of December 30, 2018, to hedge balance sheet exposure, we held forward contracts with an aggregate notional value of $11.4 million. These contracts matured in January 2019.

Interest Rate Risk

We also enter into interest rate swap agreements to reduce the impact of changes in interest rates on our project specific non-recourse floating rate debt. As of March 31, 2019 and December 30, 2018, we had interest rate swap agreements designated as cash flow hedges with aggregate notional values of $6.6 million and $6.7 million, respectively. These swap agreements allow us to effectively convert floating-rate payments into fixed rate payments periodically over the life of the agreements. These derivatives have a maturity of more than 12 months. The effective portion of these swap agreements designated as cash flow hedges is reclassified into interest expense when the hedged transactions are recognized in our condensed consolidated statements of operations. We analyze our designated interest rate swaps quarterly to determine if the hedge transaction remains effective or ineffective. We may discontinue hedge accounting for interest rate swaps prospectively if certain criteria are no longer met, the interest rate swap is terminated or exercised, or if we elect to remove the cash flow hedge designation. If hedge accounting is discontinued, and the forecasted hedged transaction is considered possible to occur, the previously recognized gain or loss on the interest rate swaps will remain in accumulated other comprehensive loss and will be reclassified into earnings during the same period the forecasted hedged transaction affects earnings or is otherwise deemed improbable to occur. All changes in the fair value of non-designated interest rate swap agreements are recognized immediately in current period earnings.

Credit Risk

Our option and forward contracts do not contain any credit-risk-related contingent features. We are exposed to credit losses in the event of nonperformance by the counterparties to these option and forward contracts. We enter into derivative contracts with high-quality financial institutions and limit the amount of credit exposure to any single counterparty. In addition, we continuously evaluate the credit standing of our counterparties.

Note 13. INCOME TAXES

Table of Contents

In the three months ended March 31, 2019, our income tax provision of $5.8 million on a loss before income taxes and equity in earnings of unconsolidated investees of $100.4 million was primarily due to the projected tax expense in foreign jurisdictions that are profitable, and a net change in valuation allowance from a foreign jurisdiction. Our income tax benefit of $2.6 million in the three months ended April 1, 2018 on a loss before income taxes and equity in earnings of unconsolidated investees of $142.8 million was primarily due to projected tax expense in foreign jurisdictions that are profitable.

In the three months ended March 31, 2019, in accordance with FASB guidance for interim reporting of income tax, we have computed our provision for income taxes based on a projected annual effective tax rate while excluding loss jurisdictions which cannot be benefited.

Total liabilities associated with uncertain tax positions were $17.8 million and $16.8 million as of March 31, 2019 and December 30, 2018, respectively. There have not been any material changes to our uncertain tax position as of March 31, 2019 as compared to our full year positions as of December 30, 2018.

Note 14. NET LOSS PER SHARE

We calculate basic net loss per share by dividing earnings allocated to common stockholders by the basic weighted average number of common shares outstanding for the period.

Diluted weighted average shares is computed using basic weighted average number of common shares outstanding plus any potentially dilutive securities outstanding during the period using the treasury-stock-type method and the if-converted method, except when their effect is anti-dilutive. Potentially dilutive securities include stock options, restricted stock units, the Upfront Warrants held by Total, and the outstanding senior convertible debentures.

The following table presents the calculation of basic and diluted net loss per share attributable to stockholders:



	Three Months Ended
(In thousands, except per share amounts)	March 31, 2019			April 1, 2018
Numerator:
Net loss attributable to stockholders	$	(89,724	)	$	(115,974	)
Denominator¹:
Basic and diluted weighted-average common shares	141,720			140,212

Basic and diluted net loss per share attributable to stockholders	$	(0.63	)	$	(0.83	)

¹As a result of our net loss attributable to stockholders for the three months ended March 31, 2019 and April 1, 2018, the inclusion of all potentially dilutive stock options, restricted stock units, and common shares under noted warrants and convertible debt would be anti-dilutive. Therefore, those stock options, restricted stock units and shares were excluded from the computation of the weighted-average shares for diluted net loss per share for such periods.

The following is a summary of outstanding anti-dilutive potential common stock that was excluded from diluted net loss per share attributable to stockholders in the following periods:

Note 16. SEGMENT AND GEOGRAPHICAL INFORMATION

In the fourth quarter of 2018, in connection with our efforts to improve operational focus and transparency, drive overhead accountability into segment operating results, and increase strategic agility across the value chain from our upstream business' core strength in manufacturing and technology to our downstream business' core strength in offering complete solutions in residential and commercial markets, we reorganized our segment reporting to an upstream and downstream structure. Previously, we operated under three end-customer segments comprised of our (i) Residential Segment, (ii) Commercial Segment, and (iii) Power Plan Segment. Historically, the Residential Segment referred to sales of solar energy solutions to residential end-customers, the Commercial Segment referred to sales of energy solutions to commercial and public entity end-customers, and the Power Plant Segment referred to our large-scale solar products and systems and component sales.

Under the new segmentation, SunPower Energy Services Segment ("SunPower Energy Services" or "Downstream") refers to sales of solar energy solutions in the North America region previously included in the legacy Residential Segment and Commercial Segment (collectively previously referred to as "Distributed Generation" or "DG") including direct sales of turn-key engineering, procurement and construction ("EPC") services, sales to our third-party dealer network, sales of energy under power purchase agreements ("PPAs"), storage solutions, cash sales and long-term leases directly to end customers, and sales to resellers. SunPower Energy Services Segment also includes sales of our global O&M services. SunPower Technologies Segment ("SunPower Technologies" or "Upstream") refers to our technology development, worldwide solar panel manufacturing operations, equipment supply to resellers and commercial and residential end-customers outside of North America ("International DG"), and worldwide power plant project development and project sales. Upon reorganization, some support functions and responsibilities, which previously resided within the corporate function, have been shifted to each segment, including financial planning and analysis, legal, treasury, tax and accounting support and services, among others.

The reorganization provides our management with a comprehensive financial overview of our key businesses. The application of this structure permits us to align our strategic business initiatives and corporate goals in a manner that best focuses our businesses and support operations for success.

Our Chief Executive Officer, as the chief operating decision maker (“CODM”), reviews our business, manages resource allocations and measures performance of our activities between the SunPower Energy Services Segment and the SunPower Technologies Segment.

Reclassifications of prior period segment information have been made to conform to the current period presentation. These changes did not materially affect our previously reported Consolidated Financial Statements.

Adjustments Made for Segment Purposes

Adjustments Based on International Financial Reporting Standards (“IFRS”)

8point3 Energy Partners

We include adjustments related to the sales of projects contributed to 8point3 Energy Partners based on the difference between the fair market value of the consideration received and the net carrying value of the projects contributed, of which, a portion was deferred in proportion to our retained equity interest in 8point3 Energy Partners, at the time. Prior to the adoption of ASC 606, these sales were recognized under either real estate, lease, or consolidation accounting guidance depending upon the nature of the individual asset contributed, with outcomes ranging from no, partial, or full profit recognition. We adopted ASC 606 on January 1, 2018, using the full retrospective method, which required us to restate each prior period presented. We recorded a material amount of deferred profit associated with projects sold to 8point3 Energy Partners in 2015, the majority of which had previously been deferred under real estate accounting. Accordingly, our carrying value in the 8point3 Group materially increased upon adoption which required us to evaluate our investment in 8point3 Energy Partners for other-than-temporary impairment ("OTTI"). In accordance with such evaluation, we recognized an OTTI charge on the 8point3 investment balance in fiscal 2017. On June 19, 2018, we sold our equity interest in the 8point3 Group.

Legacy utility and power plant projects

We include adjustments related to the revenue recognition of certain legacy utility and power plant projects based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligations and, when relevant, the allocation of revenue and margin to our project development efforts at the time of initial project sale.

Legacy sale-leaseback transactions

We include adjustments related to the revenue recognition on certain legacy sale-leaseback transactions entered into before December 31, 2018, based on the net proceeds received from the buyer-lessor. Under U.S. GAAP, these transactions were accounted for under the financing method in accordance with the applicable accounting guidance. Under such guidance, no revenue or profit is recognized at the inception of the transaction, and the net proceeds from the buyer-lessor are recorded as a financing liability. Imputed interest is recorded on the liability equal to our incremental borrowing rate adjusted solely to prevent negative amortization. Under IFRS, revenue and profit are recognized at the time of sale to the buyer-lessor if certain criteria are met.

Unrealized gain on equity investments

We recognize adjustments related to the fair value of equity investments with readily determinable fair value based on the changes in the stock price of these equity investments at every reporting period. Under GAAP, unrealized gains and losses due to changes in stock prices for these securities are recorded in earnings while under IFRS, an election can be made to recognize such gains and losses in other comprehensive income. Such an election was made by Total S.A.. Management believes that excluding the unrealized gain or loss on the equity investments is consistent with our internal reporting process as part of its status as a consolidated subsidiary of Total S.A. and better reflects our ongoing results.

Other Adjustments

Intersegment Gross Margin

To increase efficiencies and the competitive advantage of our technologies, SunPower Technologies sells solar modules to SunPower Energy Services based on transfer prices determined based on management's assessment of market-based pricing terms. Such intersegment sales and related costs are eliminated at the corporate level to derive our condensed consolidated financial results.

Impairment of residential lease assets

In the fourth quarter of fiscal 2017, we made the decision to sell or refinance our interest in the Residential Lease Portfolio and as a result of this triggering event, determined it was necessary to evaluate the potential for impairment in our ability to recover the carrying amount of the Residential Lease Portfolio. In accordance with such evaluation, we recognized a non-cash impairment charge on our solar power systems leased and to be leased and an allowance for losses related financing receivables. In connection with the impairment loss, the carrying values of our solar power systems leased and to be leased were reduced which resulted in lower depreciation charges. In the fourth quarter of fiscal 2018, we sold membership units representing a 49% membership interest in our residential lease business and retained a 51% membership interest. The loss on divestment and the remaining unsold residential lease assets impairment with its corresponding depreciation savings are excluded from our segment results as they are non-cash in nature and not reflective of ongoing operating results.

Construction revenue on solar services contracts

Upon adoption of the new lease accounting guidance ("ASC 842") in the first quarter of fiscal 2019, revenue and cost of revenue on solar services contracts with residential customers are recognized ratably over the term of those contracts, beginning when the projects are placed in service. For segment reporting purposes, we recognize revenue and cost of revenue upfront based on the expected cash proceeds to align with the legacy lease accounting guidance. Management believes it is appropriate to recognize revenue and cost of revenue upfront based on total expected cash proceeds, as it better reflects our ongoing results as such method aligns revenue and costs incurred most accurately in the same period.

Cost of above-market polysilicon

As described in "Note 9. Commitments and Contingencies," we have entered into multiple long-term, fixed-price supply agreements to purchase polysilicon for periods of up to ten years. The prices in select legacy supply agreements, which include a cash portion and a non-cash portion attributable to the amortization of prepayments made under the agreements, significantly exceed current market prices. Additionally, in order to reduce inventory and improve working capital, we have periodically elected to sell polysilicon inventory in the marketplace at prices below our purchase price, thereby incurring a loss. We have excluded the impact of our above-market cost of polysilicon, including the effect of above-market polysilicon on product costs, losses incurred on sales of polysilicon to third parties, and inventory reserves and project asset impairments recorded as a result of above-market polysilicon, from our segment results.

Stock-based compensation

We incur stock-based compensation expense related primarily to our equity incentive awards. We exclude this expense from our segment results.

Amortization of intangible assets

We incur amortization expense on intangible assets as a result of acquisitions, which include patents, project assets, purchased technology, in-process research and development and trade names. We exclude this expense from our segment results.

Depreciation of idle equipment

We changed the deployment plan for our next generation of solar cell technology, and revised our depreciation estimates to reflect the use of certain assets over their shortened useful life. Such asset depreciation is excluded from our operating results as it is non-cash in nature and not reflective of ongoing operating results.

Gain on business divestiture

On March 26, 2019, we entered into a transaction pursuant to which we sold membership interest in certain of our subsidiaries that own leasehold interests in projects subject to sale-leaseback financing arrangements. In connection with this sale, we recognized a gain relating to this business divestiture. Management believes that it is appropriate to exclude this gain from our segment results as it is not reflective of ongoing operating results.

Transaction-related costs

In connection with material transactions such as acquisition or divestiture of a business, we incurred transaction costs including legal and accounting fees. Management believes that it is appropriate to exclude these costs from our segment results as they would not have otherwise been incurred as part of its business operations and are therefore not reflective of ongoing operating results.

Business reorganization costs

In connection with the reorganization of our business into an upstream and downstream business unit structure, we incurred and expect to continue incurring expenses in the upcoming quarters associated with reclassifying prior period segment information, reorganization of corporate functions and responsibilities to the business units, updating accounting policies and processes and implementing systems to fulfill the requirements of the master supply agreement between the segments. We believe that it is appropriate to exclude these from our segment results as they would not have otherwise been incurred as part of its business operations and are therefore not reflective of ongoing operating results.

Restructuring charges (credits)

We incur restructuring expense related to reorganization plans aimed towards realigning resources consistent with our global strategy and improving our overall operating efficiency and cost structure. We exclude this expense from our segment results.

Non-cash interest expense

We incur non-cash interest expense related to the amortization of items such as original issuance discounts on certain of our convertible debt. We exclude this expense from our segment results.

For more information about our business, please refer to the section titled "Part I. Item 1. Business" in our Annual Report on Form 10-K for the fiscal year ended December 30, 2018.

Recent Developments

Effective December 31, 2018, we adopted Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842), as amended ("ASC 842") using the optional transition method as discussed in "Part I-Item 1. Financial Statements-Notes to the Consolidated Financial Statements-Note 1. Organization and Summary of Significant Accounting Policies" of this Quarterly Report on Form 10-Q. All amounts and disclosures set forth in this Form 10-Q reflect these changes.

Table of Contents

Key transactions during the fiscal quarter ended March 31, 2019 include the following:

Sale of Commercial Sale-Leaseback Portfolio

We enter into sale-leaseback arrangements under which solar power systems are sold to third parties and subsequently leased back by us over lease terms of up to 25 years. Separately, we enter into sales of energy under power purchase agreements ("PPAs") with end customers, who host the leased solar power systems and buy the electricity directly from us under PPAs with terms of up to 25 years. At the end of the lease term, we have the option to purchase the systems at fair value or may be required to remove the systems and return them to the third parties.

Segments Overview

In the fourth quarter of fiscal 2018, in connection with our efforts to improve operational focus and transparency, drive overhead accountability into segment operating results, and increase strategic agility across the value chain from our upstream business' core strength in manufacturing and technology to our downstream business's core strength in offering complete solutions in residential and commercial markets, we reorganized our segment reporting to an upstream and downstream structure. Previously, we operated under three end-customer segments, comprised of our (i) Residential Segment, (ii) Commercial Segment, and (iii) Power Plant Segment. Historically, the Residential Segment referred to sales of solar energy solutions to residential end-customers, the Commercial Segment referred to sales of energy solutions to commercial and public entity end-customers, and the Power Plant Segment referred to our large-scale solar products and systems and component sales.

Table of Contents

development, worldwide solar panel manufacturing operations, equipment supply to resellers and commercial and residential end-customers outside of North America ("International DG"), and worldwide power plant project development and project sales. Upon reorganization, some support functions and responsibilities, which previously resided within the corporate function, have been shifted to each segment, including financial planning and analysis, legal, treasury, tax and accounting support and services, among others.

For more information about our business segments, see the section titled "Part I. Item 1. Business" of our Annual Report on Form 10-K for the fiscal year ended December 30, 2018. For more segment information, see "Item 1. Financial Statements—Note 16. Segment Information and Geographical Information" in the Notes to the condensed consolidated financial statements in this Quarterly Report on Form 10-Q.

Outlook

Demand

During fiscal 2018, we faced market challenges, including competitive solar product pricing pressure including the impact of tariffs imposed pursuant to Section 201 and Section 301 of the Trade Act of 1974. On January 23, 2018, the President of the United States issued Proclamation 9693, which approved recommendations to provide relief to U.S. manufacturers and imposed safeguard tariffs on imported solar cells and modules, based on the investigations, findings, and recommendations of the International Trade Commission. The tariffs went into effect on February 7, 2018. While solar cells and modules based on interdigitated back contact ("IBC") technology, like our Maxeon 3, Maxeon 2 and related products, were granted exclusion from these safeguard tariffs on September 19, 2018, our solar products based on other technologies continue to be subject to the safeguard tariffs. Additionally, the Office of the United States Trade Representative (“USTR”) initiated an investigation under Section 301 of the Trade Act of 1974 into the government of China’s acts, policies, and practices related to technology transfer, intellectual property, and innovation. The USTR imposed additional import duties of up to 25% on certain Chinese products covered by the Section 301 remedy. These tariffs include certain solar power system components and finished products, including those purchased from our suppliers for use in our products and used in our business. In the near term, imposition of these tariffs - on top of anti-dumping and countervailing duties on Chinese solar cells and modules, imposed under the prior administration - is likely to result in a wide range of impacts to the U.S. solar industry, global manufacturing market and our business. Such tariffs could cause market volatility, price fluctuations, and demand reduction. Uncertainties associated with the Section 201 and Section 301 trade cases prompted us to adopt a restructuring plan and implement initiatives to reduce operating expenses and cost of revenue overhead and improve cash flow. During fiscal 2018, we incurred total tariffs charges of approximately $42.5 million.

In fiscal 2019, we continue to focus on investments that we expect will offer the best opportunities for growth including our industry-leading Maxeon 5 cell and panel technology, solar-plus-storage solutions and digital platform to improve customer service and satisfaction in our SunPower Energy Services offerings. We believe that our strategic decision to re-segment our business into an upstream and downstream structure, to focus our downstream efforts on our leading U.S. DG business while growing global sales of our upstream solar panel business through our SunPower Solutions group, will improve transparency and enable us to regain profitability in 2019.

In late fiscal 2015, the U.S. government enacted a budget bill that extended the solar commercial investment tax credit (the "Commercial ITC") under Section 48(c) of the Internal Revenue Code of 1986, as amended (the "Code"), and the individual solar investment tax credit under Section 25D of the Code (together with the Commercial ITC, the "ITC") for five years, at rates gradually decreasing from 30% through 2019 to 22% in 2021. After 2021, the Commercial ITC is retained at 10%. During December 2017, the current administration and Congress passed comprehensive reform of the Code which resulted in the reduction or elimination of various industry-specific tax incentives in return for an overall reduction in corporate tax rates. These changes are likely to result in a wide range of impacts to the U.S. solar industry and our business. For more information about the ITC and other policy mechanisms, please refer to the section titled "Item 1. Business—Regulations—Public Policy Considerations" of our Annual Report on Form 10-K for the fiscal year ended December 30, 2018. For more information about how we avail ourselves of the benefits of public policies and the risks related to public policies, please see

Table of Contents

the risk factors set forth under the caption "Part I. Item 1A. Risk Factors—Risks Related to Our Sales Channels," including "—The reduction, modification or elimination of government incentives could cause our revenue to decline and harm our financial results" and "—Existing regulations and policies and changes to these regulations and policies may present technical, regulatory, and economic barriers to the purchase and use of solar power products, which may significantly reduce demand for our products and services" of our Annual Report on Form 10-K for the fiscal year ended December 30, 2018.

Supply

We are focused on delivering complete solar power generation solutions to our customers. As part of our solutions-focused approach, we launched our SunPower Helix product for our commercial business customers during fiscal 2015 and our SunPower Equinox product for our residential business customers during fiscal 2016. The Equinox and Helix systems are pre-engineered modular solutions for residential and commercial applications, respectively, that combine our high-efficiency solar module technology with integrated plug-and-play power stations, cable management systems, and mounting hardware that enable our customers to quickly and easily complete system installations and manage their energy production. Our Equinox systems utilize our latest Maxeon Gen 3 cell and ACPV technology for residential applications, where we are also expanding our initiatives on storage and Smart Energy solutions. During fiscal 2016 we also launched our next generation technology for our existing Oasis modular solar power blocks for power plant applications. With the addition of these modular solutions in our residential and commercial applications, we are able to provide complete solutions across all end-customers. Additionally, we continue to focus on producing our new lower cost, high efficiency P-Series product line, which will enhance our ability to rapidly expand our global footprint with minimal capital cost.

We continue to see significant and increasing opportunities in technologies and capabilities adjacent to our core product offerings that can significantly reduce our customers' CCOE, including the integration of energy storage and energy management functionality into our systems, and have made investments to realize those opportunities, enabling our customers to make intelligent energy choices by addressing how they buy energy, how they use energy, and when they use it. We have added advanced module-level control electronics to our portfolio of technology designed to enable longer series strings and significant balance of system components cost reductions in large arrays. We currently offer solar panels that use microinverters designed to eliminate the need to mount or assemble additional components on the roof or the side of a building and enable optimization and monitoring at the solar panel level to ensure maximum energy production by the solar system.

We continue to improve our unique, differentiated solar cell and panel technology. We emphasize improvement of our solar cell efficiency and LCOE and CCOE performance through enhancement of our existing products, development of new products and reduction of manufacturing cost and complexity in conjunction with our overall cost-control strategies. We are now producing our solar cells with over 25% efficiency in the lab and have reached production panel efficiencies over 24%.

We monitor and change our overall solar cell manufacturing output in an ongoing effort to match profitable demand levels, with increasing bias toward our highest efficiency Maxeon 3 product platform, which utilizes our latest solar cell technology, and our P-Series product, which utilizes conventional cell technology that we purchase from third parties in low-cost supply chain ecosystems such as China. We previously closed our Fab 2 cell manufacturing facility and our panel assembly facility in the Philippines and are focusing on our latest generation, lower cost panel assembly facilities in Mexico. As part of this realignment, we are also increasing production of our new P-Series technology, including our newly-acquired U.S. manufacturing capabilities.

We are focused on reducing the cost of our solar panels and systems, including working with our suppliers and partners along all steps of the value chain to reduce costs by improving manufacturing technologies and expanding economies of scale and reducing manufacturing cost and complexity in conjunction with our overall cost-control strategies. We believe that the global demand for solar systems is highly elastic and that our aggressive, but achievable, cost reduction roadmap will reduce installed costs for our customers across both of our business segments and drive increased demand for our solar solutions.

We also work with our suppliers and partners to ensure the reliability of our supply chain. We have contracted with some of our suppliers for multi-year supply agreements, under which we have annual minimum purchase obligations. For more information about our purchase commitments and obligations, see "Liquidity and Capital Resources—Contractual Obligations" and "Item 1. Financial Statements—Note 4. Divestiture" and "Note 9. Commitments and Contingencies" in the Notes to the condensed consolidated financial statements in this Quarterly Report on Form 10-Q.

We currently believe our supplier relationships and various short- and long-term contracts will afford us the volume of material and services required to meet our planned output; however, we face the risk that the pricing of our long-term supply contracts may exceed market value. For example, we purchase our polysilicon under fixed-price long-term supply agreements. When the pricing under these agreements significantly exceeds market value, they may result in inventory write-downs based

Table of Contents

on expected net realizable value. Additionally, existing arrangements from prior years have resulted in above current market pricing for purchasing polysilicon, resulting in inventory losses we have realized. For several years now, we have elected to sell polysilicon inventory in excess of short-term needs to third parties at a loss, and may enter into further similar transactions in future periods. For more information about these risks, see the risk factors set forth under the caption "Part 1. Item 1A. Risk Factors—Risks Related to Our Supply Chain," including "—Our long-term, firm commitment supply agreements could result in excess or insufficient inventory, place us at a competitive disadvantage on pricing, or lead to disputes, each of which could impair our ability to meet our cost reduction roadmap, and in some circumstances may force us to take a significant accounting charge" and "—We will continue to be dependent on a limited number of third-party suppliers for certain raw materials and components for our products, which could prevent us from delivering our products to our customers within required timeframes and could in turn result in sales and installation delays, cancellations, penalty payments and loss of market share" of our Annual Report on Form 10-K for the fiscal year ended December 30, 2018.

Results of Operations

	Three Months Ended
(In thousands, except percentages)	March 31, 2019			April 1, 2018			% Change
SunPower Energy Services	$	178,221		$	246,928		(28	)%
SunPower Technologies	230,804			253,834			(9	)%
Intersegment eliminations	(60,800		)	(108,874		)	(44	)%
Total revenue	$	348,225		$	391,888		(11	)%

Total Revenue:

Our total revenue decreased by 11% during the three months ended March 31, 2019 as compared to the three months ended April 1, 2018, primarily due to decrease in our SunPower Energy Services Segment attributed to lower solar services revenue as a result of ASC 842 adoption, which now precludes upfront revenue recognition on sales-type leases and lower volume sold to our commercial dealers. Decline in our SunPower Technologies Segment revenue for the three months ended March 31, 2019 compared to the three months ended April 1, 2018 is primarily attributable our decision to cease the development of large-scale solar power projects beginning in fiscal 2018.

We did not have significant customers that accounted for greater than 10% of total revenue in the three months ended March 31, 2019 and April 1, 2018.

SunPower Energy Services Segment Revenue:

Revenue from residential customers decreased 29% during the three months ended March 31, 2019 as compared to the three months ended April 1, 2018, primarily due to the adoption of new lease standards (ASC 842). Revenue from sales-type leases placed in service in the first quarter of fiscal 2018 was recognized upfront under the legacy lease accounting guidance. Such revenue is now recognized over the service period in accordance with revenue accounting guidance. Revenue from our commercial business decreased 26% during the three months ended March 31, 2019 as compared to the three months ended April 1, 2018 primarily because of lower volume of systems and components sold to dealers.

SunPower Technologies Segment Revenue:

Revenue for the segment decreased by 9% during the three months ended March 31, 2019, primarily due to reduced revenues from power plant development projects as we ceased the development of large-scale solar power projects, which was partially offset by increased module sales outside of the U.S. The intersegment revenue from module sales also decreased due to lower sales to SunPower Energy Services Segment Revenue.

Total Cost of Revenue:

Our total cost of revenue increased 1% during the three months ended March 31, 2019 as compared to the three months ended April 1, 2018, primarily due to loss on ancillary sale of above-market polysilicon, higher inventory reserve charges related to certain end-of-life products, and pre-operating capacity charges on new product developments. This increase was partially offset by impairment charges on certain solar power development projects during the three months ended April 1, 2018, and lower volume in U.S. residential and commercial sales.

Gross Margin

SunPower Energy Services Segment Gross Margin:

Gross margin for our SunPower Energy Services Segment decreased 13% during the three months ended March 31, 2019 as compared to the three months ended April 1, 2018, primarily as a result of no upfront recognition of gross margin on sales-type leases subsequent to the adoption of ASC 842, change in product mix, and fewer EPC projects compared to the three months ended April 1, 2018.

SunPower Technologies Segment Gross Margin:

Gross margin for our SunPower Technologies Segment decreased 13% during the three months ended March 31, 2019 as compared to the three months ended April 1, 2018, primarily due to loss on ancillary sale of above-market polysilicon, higher inventory reserve charges related to certain end-of-life products, and pre-operating capacity charges on new product developments, partially offset by impairment charges on certain solar power developments projects during the three months ended April 1, 2018.

As a percentage of revenue	—		%	3		%

Restructuring charges decreased $11.8 million during the three months ended March 31, 2019 as compared to the three months ended April 1, 2018, primarily because we have already incurred the majority of severance and benefits charges in connection with the February 2018 restructuring plan in prior periods. See "Item 1. Financial Statements—Note 8. Restructuring" in the Notes to the condensed consolidated financial statements in this Quarterly Report on Form 10-Q for further information regarding our restructuring plans. As a result of the February 2018 restructuring plan, we expect to generate annual cost savings of approximately $20.5 million in operating expenses, largely cash savings, primarily from a reduction in global workforce; the savings commenced in the first quarter of fiscal 2018.

Impairment of residential lease assets	$	9,226		$	49,092		(81	)%
As a percentage of revenue	3		%	13		%

In the fourth quarter of fiscal 2017, in conjunction with our efforts to generate more available liquid funds in the near-term, we made the decision to sell a portion of our interest in our Residential Lease Portfolio. As a result, in the fourth quarter of fiscal 2017, we determined it was necessary to evaluate the potential for impairment in our ability to recover the carrying amount of our Residential Lease Portfolio. As a result of our evaluation, we recognized non-cash impairment charges of $49.1 million within "impairment of residential lease assets" on the condensed consolidated statements of operations for the three months ended April 1, 2018. In November 2018, we completed the sale of the majority of our Residential Lease Portfolio to Hannon Armstrong through sale of partial equity interests in SunStrong Capital Holdings LLC ("SunStrong"), our wholly-owned subsidiary at that time. The transaction resulted in deconsolidation of SunStrong from our books, as we and Hannon Armstrong exercised joint control after the sale. In the first fiscal quarter of 2019, we continued recording additional non-cash impairment charges of $9.2 million for the remaining assets in the Residential Lease Portfolio that has yet to be sold.

Provision for income taxes	$	(5,797	)	$	(2,628	)	121	%
As a percentage of revenue	(2		)%	(1		)%

In the three months ended March 31, 2019, our income tax provision of $5.8 million on a loss before income taxes and equity in earnings of unconsolidated investees of $100.4 million was primarily due to the related tax expense in foreign jurisdictions that were profitable, and a net change in valuation allowance from foreign jurisdiction. The income tax provision of $2.6 million in the three months ended April 1, 2018 on a loss before income taxes and equity in earnings of unconsolidated investees of $142.8 million, was primarily due to the related tax expense in foreign jurisdictions that were profitable.

A material amount of our total revenue is generated from customers located outside of the United States, and a substantial portion of our assets and employees are located outside of the United States. Because of the one-time transition tax related to the Tax Cuts and Jobs Act enacted in 2017, the accumulated foreign earnings were deemed to have been taxed and were no longer subject to the U.S. federal deferred tax liability. Foreign withholding taxes have not been provided on the existing undistributed earnings of our non-U.S. subsidiaries as of March 31, 2019 as these are intended to be indefinitely reinvested in operations outside the United States.

We record a valuation allowance to reduce our deferred tax assets in the U.S., Malta, South Africa, Spain, and Mexico to the amount that is more likely than not to be realized. In assessing the need for a valuation allowance, we consider historical levels of income, expectations and risks associated with the estimates of future taxable income and ongoing prudent and feasible tax planning strategies. In the event we determine that we would be able to realize additional deferred tax assets in the future in excess of the net recorded amount, or if we subsequently determine that realization of an amount previously recorded is unlikely, we would record an adjustment to the deferred tax asset valuation allowance, which would change income tax in the period of adjustment.

On July 27, 2015, in Altera Corp. v. Commissioner, the U.S. Tax Court issued an opinion related to the treatment of stock-based compensation expense in an intercompany cost-sharing arrangement. On July 24, 2018, the Ninth Circuit Court of Appeal reversed the Tax Court’s decision made in year 2015. On August 7, 2018, the Ninth Circuit Court of Appeal withdrew the issued decision to allow for additional time to confer on the appeal. We confirmed that there were no changes to the decision and will continue to monitor for ongoing developments and potential impacts to our condensed consolidated financial statements.

Equity in Earnings (Losses) of Unconsolidated Investees

Our equity in earnings (losses) of unconsolidated investees increased $3.8 million in the three months ended March 31, 2019 as compared to the three months ended April 1, 2018, primarily driven by an increase in our share of earnings generated by certain equity investment as compared to a decrease in our share of earnings generated by the activities of the 8point3 Energy Partners and its affiliates (the "8point3 Group") during the first quarter of fiscal 2018.

We have entered into facilities with third-party tax equity investors under which the investors invest in a structure known as a partnership flip. We determined that we hold controlling interests in these less-than-wholly-owned entities and therefore we

have fully consolidated these entities. We apply the HLBV method in allocating recorded net income (loss) to each investor based on the change in the reporting period, of the amount of net assets of the entity to which each investor would be entitled to under the governing contractual arrangements in a liquidation scenario.

In the three months ended March 31, 2019 and April 1, 2018, we attributed $14.8 million and $31.6 million, respectively, of net losses primarily to the third-party investors as a result of allocating certain assets, including tax credits and accelerated tax depreciation benefits, to the investors. The $16.8 million decrease in net loss attributable to noncontrolling interests and redeemable noncontrolling interests is primarily due to deconsolidation of majority of residential lease assets in the last quarter of fiscal 2018.

Critical Accounting Estimates

We prepare our condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles, which requires management to make estimates and assumptions that affect the amounts of assets, liabilities, revenues, and expenses recorded in our financial statements. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions and conditions.

There were no significant changes in our critical accounting estimates during the fiscal quarter ended March 31, 2019 compared to those previously disclosed in “Critical Accounting Estimates” in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in the 2018 Annual Report on Form 10-K.

Net cash provided by investing activities in the three months ended March 31, 2019 was $24.5 million, which included $34.1 million in capital expenditures primarily related to the expansion of our solar cell manufacturing capacity and costs associated with solar power systems. This was partially offset by proceeds of $9.7 million from business divestiture.

Net cash used in investing activities in the three months ended April 1, 2018 was $11.6 million, which included (i) $35.3 million in capital expenditures primarily related to the expansion of our solar cell manufacturing capacity and costs associated with solar power systems, leased and to be leased; (ii) $6.3 million paid for investments in consolidated and unconsolidated investees. This was partially offset by proceeds from the sale of investment in joint ventures of $27.3 million and a $2.7 million dividend from 8point3 Energy Partners.

This was partially offset by $4.5 million in purchases of treasury stock for tax withholding obligations on vested restricted stock and a $1.3 million in net repayments of bank loans and other debt.

Debt and Credit Sources

Convertible Debentures

As of March 31, 2019, an aggregate principal amount of $425.0 million of the 4.00% senior convertible debentures due 2023 (the "4.00% debentures due 2023") remained issued and outstanding. The 4.00% debentures due 2023 were issued on December 15, 2015. Interest on the 4.00% debentures due 2023 is payable on January 15 and July 15 of each year, beginning on July 15, 2016. Holders are able to exercise their right to convert the debentures at any time into shares of our common stock at an initial conversion price approximately equal to $30.53 per share, subject to adjustment in certain circumstances. If not earlier repurchased or converted, the 4.00% debentures due 2023 mature on January 15, 2023. Holders may require us to repurchase all or a portion of their 4.00% debentures due 2023, upon a fundamental change, as described in the related indenture, at a cash repurchase price equal to 100% of the principal amount plus accrued and unpaid interest. If we undergo a non-stock change of control, as described in the related indenture, the 4.00% debentures due 2023 will be subject to redemption at our option, in whole but not in part, for a period of 30 calendar days following a repurchase date relating to the non-stock change of control, at a cash redemption price equal to 100% of the principal amount plus accrued and unpaid interest. Otherwise, the 4.00% debentures due 2023 are not redeemable at our option prior to the maturity date. In the event of certain events of default, Wells Fargo Bank, National Association ("Wells Fargo"), the trustee, or the holders of a specified amount of then-outstanding 4.00% debentures due 2023 will have the right to declare all amounts then outstanding due and payable.

As of March 31, 2019, an aggregate principal amount of $400.0 million of the 0.875% senior convertible debentures due 2021 (the “0.875% debentures due 2021”) remained issued and outstanding. The 0.875% debentures due 2021 were issued on June 11, 2014. Interest on the 0.875% debentures due 2021 is payable on June 1 and December 1 of each year. Holders are able to exercise their right to convert the debentures at any time into shares of our common stock at an initial conversion price approximately equal to $48.76 per share, subject to adjustment in certain circumstances. If not earlier repurchased or converted, the 0.875% debentures due 2021 mature on June 1, 2021. Holders may require us to repurchase all or a portion of their 0.875% debentures due 2021, upon a fundamental change, as described in the related indenture, at a cash repurchase price equal to 100% of the principal amount plus accrued and unpaid interest. If we undergo a non-stock change of control, as described in the related indenture, the 0.875% debentures due 2021 will be subject to redemption at our option, in whole but not in part, for a period of 30 calendar days following a repurchase date relating to the non-stock change of control, at a cash redemption price equal to 100% of the principal amount plus accrued and unpaid interest. Otherwise, the 0.875% debentures due 2021 are not redeemable at our option prior to the maturity date. In the event of certain events of default, Wells Fargo, the trustee, or the holders of a specified amount of then-outstanding 0.875% debentures due 2021 will have the right to declare all amounts then outstanding due and payable.

Loan Agreement with California Enterprise Development Authority ("CEDA")

On December 29, 2010, we borrowed from CEDA the proceeds of the $30.0 million aggregate principal amount of CEDA's tax-exempt Recovery Zone Facility Revenue Bonds (SunPower Corporation - Headquarters Project) Series 2010 (the "Bonds") maturing April 1, 2031 under a loan agreement with CEDA. Certain of our obligations under the loan agreement were contained in a promissory note dated December 29, 2010 issued by us to CEDA, which assigned the promissory note, along with all right, title and interest in the loan agreement, to Wells Fargo, as trustee, with respect to the Bonds for the benefit of the holders of the Bonds. The Bonds bear interest at a fixed-rate of 8.50% per annum. As of March 31, 2019, the fair value of the Bonds was $32.4 million, determined by using Level 2 inputs based on quarterly market prices as reported by an independent pricing source.

As of March 31, 2019, the $30.0 million aggregate principal amount of the Bonds was classified as "Long-term debt" in our condensed consolidated balance sheets.

Revolving Credit Facility with Credit Agricole

On June 23, 2017, we entered into an Amended and Restated Revolving Credit Agreement with Credit Agricole, as administrative agent, and the other lenders party thereto (the "Revolver"), which amends and restates the Revolving Credit Agreement dated July 3, 2013, as amended.

The Revolver was entered into in connection with a letter agreement between us and Total S.A. dated May 8, 2017 (the "Letter Agreement"), to facilitate the issuance by Total S.A. ("Total S.A.") of one or more guaranties of our payment obligations of up to $100.0 million under the Revolver. The maturity date of the Letter Agreement and the Revolver is August 26, 2019. In consideration for the commitments of Total S.A. pursuant to the Letter Agreement, we are required to pay a guarantor commitment fee of 0.50% per annum for the unutilized Support Amount and a guaranty fee of 2.35% per annum of the guaranteed amount outstanding.

Available borrowings under the Revolver are $300.0 million; provided that the aggregate principal amount of all amounts borrowed under the facility cannot exceed 95.0% of the amounts guaranteed by Total S.A. under the Letter Agreement. Amounts borrowed under the facility may be repaid and re-borrowed until the maturity date.

We are required to pay (a) interest on outstanding borrowings under the facility of (i) with respect to any LIBOR rate loan, an amount equal to 0.6% plus the LIBOR rate divided by a percentage equal to one minus the stated maximum rate of all reserves required to be maintained against “Eurocurrency liabilities” as specified in Regulation D; and (ii) with respect to any alternate base rate loan, an amount equal to 0.25% plus the greater of (1) the prime rate, (2) the Federal Funds rate plus 0.50%, and (3) the one-month LIBOR rate plus 1%; and (b) a commitment fee of 0.06% per annum on funds available for borrowing and not borrowed. The Revolver includes representations, covenants, and events of default customary for financing transactions of this type. As of March 31, 2019, we had no outstanding borrowings under the revolving credit facility.

September 2011 Letter of Credit Facility with Deutsche Bank and Deutsche Bank Trust Company Americas (together, "Deutsche Bank Trust")

On September 27, 2011, we entered into a letter of credit facility with Deutsche Bank Trust which provides for the issuance, upon request by us, of letters of credit to support our obligations in an aggregate amount not to exceed $200.0 million. Each letter of credit issued under the facility is fully cash-collateralized and we have entered into a security agreement with Deutsche Bank Trust, granting them a security interest in a cash collateral account established for this purpose.

As of March 31, 2019, letters of credit issued under the Deutsche Bank Trust facility totaled $2.6 million, which was fully collateralized with restricted cash as classified on the condensed consolidated balance sheets.

Other Facilities

Asset-Backed Loan with Bank of America

On March 29, 2019, we entered in a Loan and Security Agreement with Bank of America, N.A., which provides a revolving credit facility secured by certain inventory and accounts receivable in the maximum aggregate principal amount of $50.0 million. The Loan and Security Agreement contains negative and affirmative covenants, events of default and repayment and prepayment provisions customarily applicable to asset-backed credit facilities. The facility bears a floating interest rate of LIBOR plus an applicable margin, and matures on the earlier of March 29, 2022, a date that is 91 days prior to the maturity of

Table of Contents

our 2021 convertible debentures, or the termination of the commitments thereunder. As of March 31, 2019, we had drawn $9.0 million under this facility.

SunTrust Facility

Non-recourse Financing and Other Debt

In order to facilitate the construction, sale or ongoing operation of certain solar projects, including our residential leasing program, we regularly obtain project-level financing. These financings are secured either by the assets of the specific project being financed or by our equity in the relevant project entity and the lenders do not have recourse to our general assets for repayment of such debt obligations, and hence the financings are referred to as non-recourse. Non-recourse financing is typically in the form of loans from third-party financial institutions, but also takes other forms, including "flip partnership" structures, sale-leaseback arrangements, or other forms commonly used in the solar or similar industries. We may seek non-recourse financing covering solely the construction period of the solar project or may also seek financing covering part or all of the operating life of the solar project. We classify non-recourse financings in our condensed consolidated balance sheets in accordance with their terms; however, in certain circumstances, we may repay or refinance these financings prior to stated maturity dates in connection with the sale of the related project or similar such circumstances. In addition, in certain instances, the customer may assume the loans at the time that the project entity is sold to the customer. In these instances, subsequent debt assumption is reflected as a financing outflow and operating inflow in the condensed consolidated statements of cash flows to reflect the substance of the assumption as a facilitation of customer financing from a third party.

Liquidity

As of March 31, 2019, we had unrestricted cash and cash equivalents of $185.6 million as compared to $309.4 million as of December 30, 2018. Our cash balances are held in numerous locations throughout the world, and as of March 31, 2019, we had approximately $52.4 million held outside of the United States. This offshore cash is used to fund operations of our business in the Europe and Asia Pacific regions as well as non-U.S. manufacturing operations, which require local payment for product materials and other expenses. The amounts held outside of the United States represent the earnings of our foreign subsidiaries which under the enacted Tax Act, incurred a one-time transition tax (such amounts were previously tax deferred), however, would not result in a cash payment due to our cumulative net operating loss position. We expect total capital expenditures related to purchases of property, plant and equipment of approximately $72.3 million in fiscal 2019 in order to increase our manufacturing capacity for our highest efficiency Maxeon 3 product platform and our new P-Series technology, improve our current and next generation solar cell manufacturing technology, and other projects. In addition, while we have begun the transition away from our project development business, we still expect to invest capital to develop solar power systems and plants for sale to customers. The development of solar power plants can require long periods of time and substantial initial investments. Our efforts in this area may consist of all stages of development, including land acquisition, permitting, financing, construction, operation and the eventual sale of the projects. We often choose to bear the costs of such efforts prior to the final sale to a customer, which involves significant upfront investments of resources (including, for example, large transmission deposits or other payments, which may be non-refundable), land acquisition, permitting, legal and other costs, and in some cases the actual costs of constructing a project, in advance of the signing of PPAs and EPC contracts and the receipt of any revenue, much of which is not recognized for several additional months or years following contract signing. Any delays in disposition of one or more projects could have a negative impact on our liquidity.

Certain of our customers also require performance bonds issued by a bonding agency or letters of credit issued by financial institutions, which are returned to us upon satisfaction of contractual requirements. If there is a contractual dispute with the customer, the customer may withhold the security or make a draw under such security, which could have an adverse impact on our liquidity. Obtaining letters of credit may require adequate collateral. All letters of credit issued under our 2016 Guaranteed LC Facilities are guaranteed by Total S.A. pursuant to the Credit Support Agreement. Our September 2011 letter of credit facility with Deutsche Bank Trust is fully collateralized by restricted cash, which reduces the amount of cash available for operations. As of March 31, 2019, letters of credit issued under the Deutsche Bank Trust facility amounted to $2.6 million which were fully collateralized with restricted cash on our condensed consolidated balance sheets.

In fiscal 2011, we launched our residential lease program with dealers in the United States, in partnership with a third-party financial institution, which allows customers to obtain SunPower systems under lease agreements up to 20 years, subject to financing availability. We have entered into facilities with financial institutions that will provide financing to support additional residential solar lease projects. Under the terms of certain programs, we receive upfront payments for periods under which the third-party financial institution has agreed to assume collection risk for certain residential leases. Changes in the amount or timing of upfront payments received from the financial institutions may have an impact on our cash position within the next twelve months. The normal collection of monthly rent payments for leases placed in service is not expected to have a material impact on our cash position within the next twelve months. We have entered into multiple facilities with third-party investors under which both parties will invest in entities that hold SunPower solar power systems and leases with residential customers. In the fourth quarter of fiscal 2017, in conjunction with our efforts to generate more available liquid funds in the near-term, we made the decision to sell a portion of our interest in the Residential Lease Portfolio. As a result, we determined it was necessary to evaluate our Residential Lease Portfolio for potential impairment. For additional information, see "Item 1. Financial Statements—Note 6. Solar Services" in the Notes to the condensed consolidated financial statements in this Quarterly Report on Form 10-Q. During the three months March 31, 2019, we received $21.0 million in contributions from investors under the related facility agreements. During the fourth quarter of fiscal 2018, we successfully sold a portion of our interest in the Residential Lease Portfolio. In conjunction with our sale of the residential lease assets, we deconsolidated these less-than-wholly-owned entities in which we previously held a controlling interest. For further information, see "Item 8. Financial Statements and Supplementary Data—Note 4. Business Combinations and Divestitures" in our Annual Report on Form 10-K for the fiscal year ended December 30, 2018.

In fiscal 2019, we drew down $22.3 million of proceeds, net of issuance costs, under the loan agreements. During the fourth quarter of fiscal 2018, in conjunction with the sale of our interest in our residential lease assets portfolio we repaid these loans in full. We are actively arranging additional third-party financing for our continuing residential lease program; however, the credit markets are unpredictable, and if they become challenging, we may be unable to arrange additional financing partners for our residential lease program in future periods, which could have a negative impact on our sales. In the unlikely event that we enter into a material number of additional leases without promptly obtaining corresponding third-party financing, our cash and working capital could be negatively affected. Additionally, we have approximately 3.9 million of cash and cash equivalents within our remaining consolidated residential leasing subsidiaries that is used by those subsidiaries for their working capital needs. This cash is typically not available to us to use for general corporate purposes unless certain financial obligations are first settled. In the event that we choose to transfer cash out of these subsidiaries for general corporate purposes in the future, we would first be required to distribute a portion of the cash to lender debt reserves and investors who hold noncontrolling interests in the relevant subsidiaries. For further information, see "Item 1. Financial Statements—Note 6. Solar Services" in the Notes to the condensed consolidated financial statements" in this Quarterly Report on Form 10-Q.

Solar power plant projects often require significant up-front investments. These include payments for preliminary engineering, permitting, legal, and other expenses before we can determine whether a project is feasible. We often make arrangements with third-party financiers to acquire and build solar power systems or to fund project construction using non-recourse project debt. As of March 31, 2019, outstanding amounts related to our project financing totaled $6.5 million.

On June 23, 2017, we entered into an Amended and Restated Revolving Credit Agreement with Credit Agricole, as administrative agent, and the other lenders party thereto, which amends and restates the Revolving Credit Agreement dated July 3, 2013 by and between us, the Administrative Agent and the other parties thereto, as amended to date. The Revolver was entered into in connection with the Letter Agreement between us and Total S.A. dated May 8, 2017, which was entered into to facilitate the issuance by Total S.A of one or more guaranties of our payment obligations of up to $100.0 million under the Revolver. The maturity date of the facility under the Revolver remains August 26, 2019, and amounts borrowed under the facility may be repaid and reborrowed until the Maturity Date. Available borrowings under the Revolver remain $300.0 million; provided that the aggregate principal amount of all amounts borrowed under the facility cannot exceed 95.0% of the amounts guaranteed by Total Solar International SAS ("Total"), formerly Total Energies Nouvelles Activités USA, a subsidiary of Total S.A., under the Letter Agreement, effectively allowing us to borrow up to a maximum of $95.0 million under the Revolver. As of March 31, 2019, $300.0 million remained undrawn under our revolving credit facility with Credit Agricole.

There are no assurances, however, that we will have sufficient available cash to repay our indebtedness or that we will be able to refinance such indebtedness on similar terms to the expiring indebtedness. If our capital resources are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity investments or debt securities or obtain other debt financing. The current economic environment, however, could limit our ability to raise capital by issuing new equity or debt securities on acceptable terms, and lenders may be unwilling to lend funds on acceptable terms in the amounts that would be required to supplement cash flows to support operations. The sale of additional equity investments or convertible debt securities would result in additional dilution to our stockholders (and the potential for further dilution upon the exercise of warrants or the conversion of convertible debt) and may not be available on favorable terms or at all, particularly in light of the current

Table of Contents

conditions in the financial and credit markets. Additional debt would result in increased expenses and would likely impose new restrictive covenants which may be similar or different than those restrictions contained in the covenants under our current loan agreements and debentures. In addition, financing arrangements, including project financing for our solar power plants and letters of credit facilities, may not be available to us, or may not be available in amounts or on terms acceptable to us.

Challenging industry conditions and a competitive environment extended throughout fiscal 2018 and first quarter of fiscal 2019. Our net losses, resulting in a net use of our available cash, continued in the first quarter of fiscal 2019 and are expected to continue through the remainder of fiscal 2019. Despite the challenging industry conditions, including uncertainty around the regulatory environment, we believe that our cash and cash equivalents, including cash expected to be generated from operations, will be sufficient to meet our obligations over the next 12 months from the date of the issuance of our financial statements. We have been successful in our ability to divest certain investments and non-core assets, such as the divestiture of our equity interest in 8point3 Energy Partners LP, the sale of certain assets and intellectual property related to the production of microinverters, the sale of membership interests in our Residential Lease Portfolio, and the sale of membership interests in our Commercial Sale-Leaseback Portfolio (Note 4. Business Divestiture). Additionally, we have secured other sources of financing in connection with our liquidity needs, as well as realizing cash savings resulting from restructuring actions and cost reduction initiatives. We continue to focus on improving our overall operating performance and liquidity, including managing cash flow and working capital.

Although we have historically been able to generate liquidity, we cannot predict, with certainty, the outcome of our actions to generate liquidity as planned.

¹Convertible debt, including interest, relates to the aggregate of $825.0 million in outstanding principal amount of our senior convertible debentures on March 31, 2019. For the purpose of the table above, we assume that all holders of the outstanding debentures will hold the debentures through the date of maturity, and upon conversion, the values of the senior convertible debentures will be equal to the aggregate principal amount with no premiums.

²CEDA loan, including interest, relates to the proceeds of the $30.0 million aggregate principal amount of the Bonds. The Bonds mature on April 1, 2031 and bear interest at a fixed rate of 8.50% through maturity.

³Other debt, including interest, primarily relates to non-recourse finance projects and solar power systems and leases under our residential lease program as described in "Item 1. Financial Statements—Note 9. Commitments and Contingencies" in the Notes to the condensed consolidated financial statements in this Quarterly Report on Form 10-Q.

⁴In connection with purchase and joint venture agreements with non-public companies, we will be required to provide additional financing to such parties of up to $3.8 million, subject to certain conditions.

⁵Operating lease commitments primarily relate to certain solar power systems leased from unaffiliated third parties over minimum lease terms of up to 20 years which are classified as held-for-sale as of March 31, 2019 and various facility lease agreements including leases entered in that have not yet commenced.

⁶Sale-leaseback financing relates to future minimum lease obligations for solar power systems under sale-leaseback arrangements which were accounted for under the financing method and have been classified as held-for-sale as of March 31, 2019.

⁷Finance lease commitments primarily relate to certain buildings, manufacturing and equipment under capital leases in Europe for terms of up to 6 years.

⁸Non-cancellable purchase orders relate to purchases of raw materials for inventory and manufacturing equipment from a variety of vendors.

⁹Purchase commitments under agreements primarily relate to arrangements entered into with several suppliers, including some of our non-consolidated investees, for polysilicon, ingots, wafers, and module-level power electronics and alternating current cables, among others. These agreements specify future quantities and pricing of products to be supplied by the vendors for periods up to 5 years and there are certain consequences, such as forfeiture of advanced deposits and liquidated damages relating to previous purchases, in the event we terminate these arrangements.

¹⁰In connection with the acquisition of AUO SunPower Sdn. Bhd. in 2016, we are required to make noncancellable annual installment payments during 2019 and 2020.

Liabilities Associated with Uncertain Tax Positions

Due to the complexity and uncertainty associated with our tax positions, we cannot make a reasonably reliable estimate of the period in which cash settlement will be made for our liabilities associated with uncertain tax positions in other long-term liabilities. Therefore, they have been excluded from the table above. As of March 31, 2019 and December 30, 2018, total liabilities associated with uncertain tax positions were $17.8 million and $16.8 million, respectively, and are included within "Other long-term liabilities" in our condensed consolidated balance sheets as they are not expected to be paid within the next twelve months.

Off-Balance Sheet Arrangements

As of March 31, 2019, we did not have any significant off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of SEC Regulation S-K.

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign Currency Exchange Risk

Our exposure to movements in foreign currency exchange rates is primarily related to sales to European customers that are denominated in Euros. Revenue generated from European customers represented 8% and 6% of our total revenue in the three months ended March 31, 2019 and April 1, 2018, respectively. A 10% change in the Euro exchange rate would have impacted our revenue by approximately $2.9 million and $2.5 million in the three months ended March 31, 2019 and April 1, 2018.

In the past, we have experienced an adverse impact on our revenue, gross margin and profitability as a result of foreign currency fluctuations. When foreign currencies appreciate against the U.S. dollar, inventories and expenses denominated in foreign currencies become more expensive. An increase in the value of the U.S. dollar relative to foreign currencies could make our solar power products more expensive for international customers, thus potentially leading to a reduction in demand, our sales and profitability. Furthermore, many of our competitors are foreign companies that could benefit from such a currency fluctuation, making it more difficult for us to compete with those companies.

We currently conduct hedging activities which involve the use of option and/or forward currency contracts that are designed to address our exposure to changes in the foreign exchange rate between the U.S. dollar and other currencies. As of March 31, 2019 and December 30, 2018, we had designated outstanding cash flow hedge forward contracts with a notional value of $44.9 million and zero, respectively. As of March 31, 2019, we also had designated outstanding cash flow hedge option contracts with a notional value of $101.5 million. As of March 31, 2019 and December 30, 2018, we had non-designated outstanding forward currency contracts with aggregate notional values of $17.4 million and $11.4 million, respectively. Because we hedge some of our expected future foreign exchange exposure, if associated revenues do not materialize we could experience a reclassification of gains or losses into earnings. Such a reclassification could adversely impact our revenue, margins and results of operations. We cannot predict the impact of future exchange rate fluctuations on our business and operating results.

Credit Risk

We have certain financial and derivative instruments that subject us to credit risk. These consist primarily of cash and cash equivalents, restricted cash and cash equivalents, investments, accounts receivable, notes receivable, advances to suppliers, foreign currency option contracts, foreign currency forward contracts, bond hedge and warrant transactions. We are exposed to credit losses in the event of nonperformance by the counterparties to our financial and derivative instruments. Our investment policy requires cash and cash equivalents, restricted cash and cash equivalents, and investments to be placed with high-quality financial institutions and limits the amount of credit risk from any one issuer. We additionally perform ongoing credit evaluations of our customers’ financial condition whenever deemed necessary and generally do not require collateral.

We enter into agreements with vendors that specify future quantities and pricing of polysilicon to be supplied for periods up to 10 years. Under certain agreements, we are required to make prepayments to the vendors over the terms of the arrangements. As of March 31, 2019 and December 30, 2018, advances to suppliers totaled $158.5 million and $171.6 million, respectively. One supplier accounted for 99.9% and 99.6% of total advances to suppliers as of March 31, 2019 and December 30, 2018, respectively.

We enter into foreign currency derivative contracts and convertible debenture hedge transactions with high-quality financial institutions and limit the amount of credit exposure to any single counterparty. The foreign currency derivative contracts are limited to a time period of a month or less. We regularly evaluate the credit standing of our counterparty financial institutions.

Interest Rate Risk

We are exposed to interest rate risk because many of our customers depend on debt financing to purchase our solar power systems. An increase in interest rates could make it difficult for our customers to obtain the financing necessary to purchase our solar power systems on favorable terms, or at all, and thus lower demand for our solar power products, reduce revenue and adversely impact our operating results. An increase in interest rates could lower a customer's return on investment in a system or make alternative investments more attractive relative to solar power systems, which, in each case, could cause our customers to seek alternative investments that promise higher returns or demand higher returns from our solar power systems, reduce gross margin and adversely impact our operating results. This risk is significant to our business because our sales model is highly sensitive to interest rate fluctuations and the availability of credit, and would be adversely affected by increases in interest rates or liquidity constraints.

Our interest expense would increase to the extent interest rates rise in connection with our variable interest rate borrowings. During the fourth quarter of fiscal 2018, we repaid all of our variable interest rate borrowings. We do not believe that an immediate 10% increase in interest rates would have a material effect on our financial statements under potential future borrowings. In addition, lower interest rates would have an adverse impact on our interest income. Due to the relatively short-term nature of our investment portfolio, we do not believe that an immediate 10% decrease in interest rates would have a material effect on the fair market value of our money market funds. Since we believe we have the ability to liquidate substantially all of this portfolio, we do not expect our operating results or cash flows to be materially affected to any significant degree by a sudden change in market interest rates on our investment portfolio.

Equity Price Risk Involving Minority Investments in Joint Ventures and Other Non-Public Companies

Our investments held in joint ventures and other non-public companies expose us to equity price risk. As of March 31, 2019 and December 30, 2018, investments of $36.3 million and $34.8 million, respectively, are accounted for using the equity method. As of both March 31, 2019 and December 30, 2018, investments of $8.8 million are accounted for using the measurement alternative method.

On August 9, 2018, we completed the sale of certain assets and intellectual property related to the production of microinverters to Enphase in exchange for $25.0 million in cash and 7.5 million shares of Enphase common stock (NASDAQ: ENPH). We received the common stock and a $15.0 million cash payment upon closing, and received the final $10.0 million cash payment of the purchase price on December 10, 2018. The common stock was recorded as an equity investment with readily determinable fair value (Level 1), with changes in fair value recognized in net income. For the three months ended March 31, 2019, we recognized an unrealized gain of $33.0 million within "Other, net" under other income (expense), net, on the condensed consolidated statement of operations. These strategic equity investments in third parties are subject to risk of changes in market value could result in realized impairment losses. We generally do not attempt to reduce or eliminate our market exposure in equity investments. We monitor these investments for impairment and record reductions in the carrying values when necessary. Circumstances that indicate an other-than-temporary decline include the valuation ascribed to the issuing company in subsequent financing rounds, decreases in quoted market prices and declines in operations of the issuer. There can be no assurance that our equity investments will not face risks of loss in the future.

Interest Rate Risk and Market Price Risk Involving Debt

As of March 31, 2019, we held outstanding convertible debentures with an aggregate face value of $825.0 million, comprised of $425.0 million of 4.00% debentures due in 2023 and $400.0 million of 0.875% debentures due in 2021. The aggregate estimated fair value of our outstanding convertible debentures was $690.5 million and $648.9 million as of March 31, 2019 and December 30, 2018, respectively. Estimated fair values are based on quoted market prices as reported by an independent pricing source. The fair market value of our debentures is subject to interest rate risk, market price risk and other factors due to the convertible feature of the debentures. The fair market value of the debentures will generally increase as interest rates fall, and decrease as interest rates rise. When our common stock price is in-the-money relative to these fixed stock price conversion rates, the fair market value of the debentures will generally increase as the market price of our common stock increases, and decrease as our common stock's market price falls, based on each debenture's respective fixed conversion rate. The interest and market value changes affect the fair market value of the debentures, but do not impact our financial position, cash flows or results of operations due to the fixed nature of the debt obligations, except to the extent increases in the value of our common stock may provide the holders the right to convert such debentures into stock, or cash, in certain instances, but only applicable during periods when our common stock is in-the-money relative to such conversion rights. As our common stock price is significantly below the conversion price for both debentures and therefore unlikely to be exercised by the holders, a 10% increase or decrease in our common stock will not impact our financial statements.

We also have interest rate risk relating to our other outstanding debt, besides debentures, all of which bear fixed rates of interest (Refer Note 11. Debt and Credit Sources). The interest and market value changes affect the fair market value of these debts, but do not impact our financial position, cash flows or results of operations due to the fixed nature of the debt obligations. A hypothetical 10 basis points increase or decrease on market interest rates related to these debts would have an immaterial impact on the fair market value of these debts.

ITEM 4: CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain "disclosure controls and procedures," as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act, that are designed to provide reasonable assurance that information required to be disclosed in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognizes that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Additionally, in designing disclosure controls and procedures, our management is required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any disclosure control and procedure also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Based on their evaluation as of the end of the period covered by this Quarterly Report on Form 10-Q, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of March 31, 2019 at a reasonable assurance level.

Changes in Internal Control over Financial Reporting

We regularly review our system of internal control over financial reporting and make changes to our processes and systems to improve controls and increase efficiency, while ensuring that we maintain an effective internal control environment. Changes may include such activities as implementing new, more efficient systems, consolidating activities, and migrating processes.

There were no changes in our internal control over financial reporting that occurred during our most recent fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
