The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the accompanying financial statements and related notes. The following discussion contains "forward-looking statements" that reflect our future plans, estimates, beliefs, and expected performance. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of a variety of risks and uncertainties, including those described in "Cautionary Note Regarding Forward-Looking Statements," our Annual Report under the heading "Item 1A. Risk Factors," and in Part II - Other Information, Item 1A. Risk Factors included herein. We assume no obligation to update any of these forward-looking statements. Overview We are an independent provider of hydraulic fracturing services and goods to onshore oil and natural gas exploration and production ("E&P") companies inNorth America . We have grown from one active hydraulic fracturing fleet inDecember 2011 to 24 active fleets in the first quarter of 2020, including the addition of one fleet inJanuary 2020 . We provide our services primarily in thePermian Basin , theEagle Ford Shale , theDJ Basin , theWilliston Basin , theSan Juan Basin , and thePowder River Basin . Recent Trends and Outlook During the first quarter, the COVID-19 pandemic emerged and put large downward pressure on the global economy and oil demand, as the global response to COVID-19 has predominantly resulted in various forms of lockdown measures to limit the spread of the disease. COVID-19, combined with the initial failure of OPEC+ to come to agreement driving oil supply upward beginning in April, led to a historic collapse in global oil prices. The estimated collapse in worldwide demand for oil is now approximately 30 million barrels a day, and oil storage is rapidly reaching capacity. West Texas Intermediate ("WTI") crude oil price has declined approximately 75% sinceJanuary 2020 . In response, OPEC+ has subsequently agreed to substantial production cuts. North American operators have begun to shut-in production due to both price and storage capacity constraints. In addition, these operators have announced significant cuts to planned 2020 capital expenditures that have led to a plunging rig count and the most abrupt curtailment of frac activity ever. The extent and duration of the continued global impact of the COVID-19 pandemic is unknown. The destruction of demand for oil caused by the COVID-19 lockdowns began to have a negative impact on the North American oil and gas sector in the later part of the first quarter. With the worldwide economic disruptions continuing and the rapid filling of remaining oil storage capacity, we anticipate this magnitude of previously unseen market imbalances to create a period characterized by uncertain, fluid and volatile operating conditions on a historic scale for the North American energy industry. We are unable to predict the degree and duration of many factors that may impact our future operating results. These factors include, but may not be limited to, the effectiveness of global and regional efforts to combat the virus; sovereign and market responses to the continuing effects of the pandemic; and business and consumer behavior as lockdown measures are relaxed. The volatile global economic conditions stemming from the pandemic, the liquidity situation for North American oil producers and the reaction of international oil producers could also exacerbate the risk factors identified in our Annual Report on Form 10-K for the fiscal year endedDecember 31, 2019 . The impacts of the COVID-19 pandemic may also materially adversely affect our results in a manner that is either not currently known or that we do not currently consider to be a significant risk to our business. See also the risk factor relating to COVID-19 disclosed in Item. 1A-Risk Factors of this quarterly report. In response to these developments, the continued duration and ultimate severity of which is unknown, we have taken the following steps to protect our employees, customers and business. DuringFebruary 2020 we formed a COVID-19 response team to implement safety procedures and contingency plans at both our customer locations and in our facilities to ensure our ability to continue providing safe and efficient services to our customers, while protecting the health of both employees and customers. We have been proactive in protecting our business during these unprecedented events. We moved quickly to preserve cash and protect our balance sheet and announced strategic actions earlier this month to align our cost structure with demand for frac services. Regrettably, for the first time in the Company's history we undertook a reduction of our personnel and staffed fleet count by approximately 50%. We also suspended variable compensation plans and our 401(k) match, implemented base salary reductions, executive and director compensation reductions, operating cost rationalization, reduction of planned 2020 capital expenditures, and suspended our quarterly dividend. Further, we have implemented a company-wide employee furlough plan that flexes our cost structure to align with the uncertain level of frac demand in the coming months. Prior to the emergence of the COVID-19 pandemic, the pricing dynamic for hydraulic fracturing services entering into 2020 was challenging. Demand for hydraulic fracturing services and goods is predominantly influenced by the level of drilling and completion activity by E&P companies, which, in turn, depends largely on the current and anticipated profitability of developing oil and natural gas reserves, the availability of capital to E&P companies, and takeaway capacity in each basin. During 2018 and 2019, and continuing into 2020, E&P companies have increasingly come under investor pressure for better 19 -------------------------------------------------------------------------------- Table of Contents returns than those achieved over the last decade which has negatively impacted the demand for fracturing services. As a result, debt and equity capital markets, which previously funded drilling and completions activity beyond E&P companies' operating cash flow, tightened, causing an increased level of capital discipline that has resulted in a lower level of drilling and completions expenditures. 2019 E&P capital expenditures were lower than those in 2018, and going into 2020 capital expenditures were expected to be less than 2019. During March andApril 2020 , in response to falling oil prices from excess worldwide supply and exacerbated by the unprecedented decline in demand for oil as a result of the global response to the COVID-19 pandemic, North American E&P companies announced significant planned 2020 capital expenditure budget reductions widely forecast to be 40% lower than 2020 capital expenditure budgets originally announced during theDecember 2019 toJanuary 2020 reporting cycle. Total industry horizontal frac stages inNorth America were up marginally in 2019, 6% from 2018, compared to a 34% increase in 2018 from 2017, according toCoras Research, LLC . However, efficiency gains across the industry have raised the number of frac stages completed by each fleet, which implies a decrease in the active frac fleets needed to meet demand. The slowing pace of frac activity led to progressively lower demand for frac fleets through the second half of 2019, resulting in pricing pressure on our services. The substantial oversupply of frac equipment in the second half of 2019 was the pricing backdrop for 2020 dedicated fleet negotiations. While the Company and many of its competitors have announced reductions in fleet count in response to COVID-19 induced market developments, the timing, depth and duration of fleet count reductions, combined with the demand factors described above, will impact pricing for hydraulic fracturing services in future periods. The price of WTI crude oil has decreased from 2019. In the first quarter of 2020, the price of WTI averaged$45.34 compared with an average of$56.84 for the fourth quarter of 2019 and an average of$54.82 for the first quarter of 2019. Additionally, in the first quarter of 2020, the horizontal rig count inNorth America averaged 703 compared to 715 in the fourth quarter of 2019 and 919 in the first quarter of 2019, according to a report byBaker Hughes , aGE company. Subsequent toMarch 31, 2020 , the price of WTI has averaged$16.71 throughApril 24, 2020 , and the most recentBaker Hughes horizontal rig count forNorth America was 426 rigs reported as ofApril 24, 2020 . While we cannot predict with any certainty when demand for, or pricing of, our frac services will increase, we would not expect demand or pricing to improve until worldwide oil supply better balances with demand. As such, there is significant uncertainty in the market about the timing and level of customers' drilling and completion activity in 2020. Based on our current visibility into our customers' plans for the remainder of 2020, we believe decreased levels of demand will likely persist at least through the second and third quarters of 2020. Results of Operations Three months endedMarch 31, 2020 compared to three months endedMarch 31, 2019 Three months ended March 31, Description 2020 2019 Change (in thousands) Revenue$ 472,344 $ 535,148 $ (62,804) Cost of services, excluding depreciation and amortization shown separately 392,716 429,299 (36,583) General and administrative 28,613 22,088 6,525 Depreciation and amortization 44,831 38,387 6,444 (Gain) loss on disposal of assets (102) 1,223 (1,325) Operating income 6,286 44,151 (37,865) Interest expense, net 3,608 4,182 (574) Net income before income taxes 2,678 39,969 (37,291) Income tax expense 261 6,060 (5,799) Net income 2,417 33,909 (31,492) Less: Net income attributable to non-controlling interests 697 15,788 (15,091) Net income attributable to Liberty Oilfield Services Inc. stockholders$ 1,720 $ 18,121 $ (16,401) 20
-------------------------------------------------------------------------------- Table of Contents Revenue Our revenue decreased$62.8 million , or 11.7%, to$472.3 million for the three months endedMarch 31, 2020 compared to$535.1 million for the three months endedMarch 31, 2019 . The decrease was due to an 13.7% decrease in revenue per average active fleet, partially offset by a 2.2% increase in average active fleets deployed. Our revenue per average active fleet decreased to approximately$20.7 million for the three months endedMarch 31, 2020 as compared to approximately$24.0 million for the three months endedMarch 31, 2019 , with 22.8 and 22.3 average active fleets deployed during those respective periods. The decrease in revenue per average active fleet is due to the oversupply of staffed frac fleets combined with reduced demand from lower customer activity industry wide, resulting in lower prices for our services. As mentioned above in Recent Trends and Outlook, inApril 2020 , we reduced our staffed fleet count by approximately 50% and have further implemented furloughs to match customer activity levels which are expected to remain suppressed in the coming months as customers have adjusted their completion plans in light of market imbalances resulting from the COVID-19 pandemic. Cost of Services Cost of services (excluding depreciation and amortization) decreased$36.6 million , or 8.5%, to$392.7 million for the three months endedMarch 31, 2020 compared to$429.3 million for the three months endedMarch 31, 2019 , which is consistent with the decrease in operations and revenues discussed above. The decrease in expense is primarily attributed to a decrease in material costs of$32.6 million or 11.9% due to the lower cost for local sand for the three months endedMarch 31, 2020 compared to the same period in 2019. General and Administrative General and administrative expenses increased$6.5 million , or 29.5%, to$28.6 million for the three months endedMarch 31, 2020 compared to$22.1 million for the three months endedMarch 31, 2019 primarily related to an increase in allowance for credit losses of$2.5 million and, to a lesser extent, due to increased accounting, legal and information technology costs for the three months endedMarch 31, 2020 . In addition, non-cash stock based compensation expense increased to$3.0 million for the three months endedMarch 31, 2020 compared to$2.0 million for the comparable period in 2019. Depreciation and Amortization Depreciation and amortization expense increased$6.4 million , or 16.8%, to$44.8 million for the three months endedMarch 31, 2020 compared to$38.4 million for the three months endedMarch 31, 2019 , due to one additional hydraulic fracturing fleet being deployed as well as an increase in finance lease assets. (Gain) loss on disposal of assets (Gain) loss on disposal of assets increased$1.3 million to a gain of$0.1 million for the three months endedMarch 31, 2020 compared to a loss of$1.2 million for the three months endedMarch 31, 2019 , attributed to the disposition of assets, primarily related to light duty vehicles. Operating Income We realized operating income of$6.3 million for the three months endedMarch 31, 2020 compared to$44.2 million for the three months endedMarch 31, 2019 , a decrease of$37.9 million , or 85.8%. The decrease is primarily due to the$62.8 million , or 11.7%, decrease in total revenue only partially offset by a$24.9 million decrease in total operating expenses, the significant components of which are discussed above. The decline in operating income was significantly impacted by reduced customer work particularly duringMarch 2020 as a result of the COVID-19 pandemic. Interest Expense, net Interest expense, net was consistent between periods, decreasing slightly by$0.6 million during the three months endedMarch 31, 2020 compared to the three months endedMarch 31, 2019 . Net Income before Income Taxes We realized net income before income taxes of$2.7 million for the three months endedMarch 31, 2020 compared to$40.0 million for the three months endedMarch 31, 2019 . The decrease is primarily attributable to a decrease in revenue, as discussed above, related to the decrease in pricing and activity, offset by the deployment of one additional hydraulic fracturing fleet during the twelve months endedMarch 31, 2020 . Income Tax Expense We recognized tax expense of$0.3 million for the three months endedMarch 31, 2020 , at an effective rate of 9.7%, compared to$6.1 million , at an effective rate of 15.2%, recognized during the three months endedMarch 31, 2019 . This 21 -------------------------------------------------------------------------------- Table of Contents decrease in income tax expense is attributable to the net decrease in operating income, the significant components of which are discussed above. Although the Company's tax rate was 9.7% for the three months endedMarch 31, 2020 , the Company expects the effective tax rate to be approximately 16.2% for the full year endedDecember 31, 2020 . The rate is lower for the three months endedMarch 31, 2020 due to discrete items recorded related to the Company's response to the CARES Act. The CARES Act allowed the Company to carry back NOLs incurred during the year endedDecember 31, 2019 which allowed for the recognition of tax attributes during the three months endedMarch 31, 2020 . Comparison of Non-GAAP Financial Measures We view EBITDA and Adjusted EBITDA as important indicators of performance. We define EBITDA as net income before interest, income taxes, and depreciation and amortization. We define Adjusted EBITDA as EBITDA adjusted to eliminate the effects of items such as new fleet or new basin start-up costs, costs of asset acquisitions, gain or loss on the disposal of assets, asset impairment charges, allowance for credit losses, and nonrecurring expenses that management does not consider in assessing ongoing performance. Our board of directors, management, investors, and lenders use EBITDA and Adjusted EBITDA to assess our financial performance because it allows them to compare our operating performance on a consistent basis across periods by removing the effects of our capital structure (such as varying levels of interest expense), asset base (such as depreciation and amortization), and other items that impact the comparability of financial results from period to period. We present EBITDA and Adjusted EBITDA because we believe they provide useful information regarding the factors and trends affecting our business in addition to measures calculated under GAAP. Note Regarding Non-GAAP Financial Measures EBITDA and Adjusted EBITDA are not financial measures presented in accordance with GAAP. We believe that the presentation of these non-GAAP financial measures will provide useful information to investors in assessing our financial performance and results of operations. Net income is the GAAP measure most directly comparable to EBITDA and Adjusted EBITDA. Our non-GAAP financial measures should not be considered as alternatives to the most directly comparable GAAP financial measure. Each of these non-GAAP financial measures has important limitations as an analytical tool due to exclusion of some but not all items that affect the most directly comparable GAAP financial measures. You should not consider EBITDA or Adjusted EBITDA in isolation or as substitutes for an analysis of our results as reported under GAAP. Because EBITDA and Adjusted EBITDA may be defined differently by other companies in our industry, our definitions of these non-GAAP financial measures may not be comparable to similarly titled measures of other companies, thereby diminishing their utility. The following tables present a reconciliation of EBITDA and Adjusted EBITDA to our net income, which is the most directly comparable GAAP measure for the periods presented: Three months endedMarch 31, 2020 compared to three months endedMarch 31, 2019 : EBITDA and Adjusted EBITDA Three Months Ended March 31, Description 2020 2019 Change (in thousands) Net income$ 2,417 $ 33,909 $ (31,492) Depreciation and amortization 44,831 38,387 6,444 Interest expense 3,608 4,182 (574) Income tax expense 261 6,060 (5,799) EBITDA$ 51,117 $ 82,538 $ (31,421) Fleet start-up costs - 1,054 (1,054) (Gain) loss on disposal of assets (102) 1,223 (1,325) Provision for credit losses 2,523 - 2,523 Adjusted EBITDA$ 53,538 $ 84,815 $ (31,277) EBITDA was$51.1 million for the three months endedMarch 31, 2020 compared to$82.5 million for the three months endedMarch 31, 2019 . Adjusted EBITDA was$53.5 million for the three months endedMarch 31, 2020 compared to$84.8 million for the three months endedMarch 31, 2019 . The decreases in EBITDA and Adjusted EBITDA resulted from decreases in revenue only partially offset by a decreases in operating expenses. See factors described under the captions Revenue and Cost of Services above. 22 -------------------------------------------------------------------------------- Table of Contents Liquidity and Capital Resources Overview Historically, our primary sources of liquidity have been cash flows from operations, proceeds from our IPO, and borrowings under our Credit Facilities. We expect to fund operations and organic growth with cash on hand, cash flows from operations and available borrowings under our Credit Facilities. We may incur additional indebtedness or issue equity securities in order to fund growth opportunities that we pursue via acquisition. Our primary uses of capital have been capital expenditures to support organic growth and funding ongoing operations, including maintenance and fleet upgrades. In response to the COVID-19 pandemic, we took significant steps to enhance our financial position through an uncertain duration of reduced activity levels. We reduced our planned 2020 capital expenditures budget by approximately 50% to between$70 and$90 million . We reduced our fleet and personnel count by approximately 50% and significantly reduced cash compensation costs through a combination of suspended variable compensation plans and matching 401(k) contributions as well as reductions to base salaries. We suspended our quarterly dividend inApril 2020 . We also implemented a furlough program that enables the Company to better align personnel costs with customer activity levels. While the Company is unable to accurately foresee future impacts from the COVID-19 pandemic, including the potential impact of periodically adjusted borrowing base limits, levels of hedged production, or unforeseen well shut-ins on our customers' ability to timely pay receivables when due, we believe our financial resources and liquidity levels, along with various contingency plans to reduce costs, are sufficient to manage the impact currently anticipated from the pandemic. Consistent with seasonal trends as first quarter activity increases from fourth quarter, cash and cash equivalents temporarily decreased by$56.2 million to$56.5 million as ofMarch 31, 2020 compared to$112.7 million as ofDecember 31, 2019 , while working capital excluding cash increased$68.4 million . We have no debt maturities beyond a 1% quarterly amortization payment of$0.4 million until September of 2022. We believe that our operating cash flow and available borrowings under our Credit Facilities will be sufficient to fund our operations for at least the next twelve months. Cash Flows The following table summarizes our cash flows for the periods indicated: Three Months Ended March 31, Description 2020 2019 Change (in thousands)
Net cash provided by operating activities
$ (49,263) Net cash used in investing activities (45,078) (66,184)

Analysis of Cash Flow Changes Between the Three Months EndedMarch 31, 2020 and 2019 Operating Activities. Net cash provided by operating activities was$0.2 million for the three months endedMarch 31, 2020 , compared to$49.5 million for the three months endedMarch 31, 2019 . The$49.3 million decrease in cash from operating activities is primarily attributable to$55.3 million cash used due to increases in working capital for the three months endedMarch 31, 2020 , compared to$28.5 million cash used due to increases in working capital for the three months endedMarch 31, 2019 . In addition to this decrease of$26.8 million , lower revenue of$62.8 million partially offset by lower cost of services of$36.6 million and higher general and administrative expenses of$6.5 million reduced cash provided by operating activities. Investing Activities. Net cash used in investing activities was$45.1 million for the three months endedMarch 31, 2020 , compared to$66.2 million for the three months endedMarch 31, 2019 . The decrease in net cash used in investing activities is attributable to the Company deploying one fleet during the three months endedMarch 31, 2020 compared to deploying one fleet and purchasing additional pump down and spare equipment to add to existing fleets during the three months endedMarch 31, 2019 . Financing Activities. Net cash used in financing activities was$11.3 million for the three months endedMarch 31, 2020 , compared to net cash used in financing activities of$27.9 million for the three months endedMarch 31, 2019 . The$16.6 million decrease in cash used in financing activities was primarily due to$18.4 million used to repurchased shares of Class A Common Stock during the three months endedMarch 31, 2019 compared to no repurchases in the three months endedMarch 23 -------------------------------------------------------------------------------- Table of Contents 31, 2020, offset by$2.8 million in payments made under the TRAs in the current period compared to$0.2 million in the prior period. ABL Facility The Company's ABL Facility provides for a line of credit up to$250.0 million , subject to certain borrowing base limitations based on a percentage of eligible accounts receivable and inventory. As ofMarch 31, 2020 , the borrowing base was calculated to be$203.0 million , and the Company had no borrowings outstanding, except for letter of credit in the amount of$0.3 million , resulting in$202.7 million of availability. Borrowings under the ABL Facility bear interest at LIBOR or a base rate, plus an applicable LIBOR margin of 1.5% to 2.0% or base rate margin of 0.5% to 1.0%, as defined in the ABL Facility credit agreement. The average monthly unused commitment is subject to an unused commitment fee of 0.375% to 0.5%. Interest and fees are payable in arrears at the end of each month, or, in the case of LIBOR loans, at the end of each interest period. The ABL Facility matures on the earlier of (i)September 19, 2022 and (ii) to the extent the debt under the Term Loan Facility remains outstanding, 90 days prior to the final maturity of the Term Loan Facility, which matures onSeptember 19, 2022 . Borrowings under the ABL Facility are collateralized by accounts receivable and inventory, and further secured by the Company,Liberty LLC , andR/C IV Non-U.S. LOS Corp. , aDelaware corporation and a subsidiary of the Company, as parent guarantors. Income Taxes The Company is a corporation and is subject toU.S. federal, state, and local income tax on its share ofLiberty LLC's taxable income. The Company recognized income tax expense of$0.3 million , effective combinedU.S. federal and state income tax rate applicable to the Company of 9.7%, for the three months endedMarch 31, 2020 compared to$6.1 million , combined effective rate of 15.2%, for the three months endedMarch 31, 2019 . Although the Company's tax rate is 9.7% for the three months endedMarch 31, 2020 , the Company expects the effective tax rate to be approximately 16.2% for the full year endedDecember 31, 2020 . The rate is lower for the three months endedMarch 31, 2020 due to discrete items recorded related to the Company's response to the CARES Act. The CARES Act allowed the Company to carry back NOLs incurred during the year endedDecember 31, 2019 which allowed for the recognition of tax attributes during the three months endedMarch 31, 2020 . The Company's effective tax rate is significantly less than the statutory federal tax rate of 21.0% primarily because no taxes are payable by the Company for the non-controlling interest's share ofLiberty LLC's pass-through results for federal, state, and local income tax reporting. Tax Receivable Agreements In connection with the IPO, onJanuary 17, 2018 , the Company entered into two TRAs with the TRA Holders. The TRAs generally provide for the payment by the Company of 85% of the net cash savings, if any, inU.S. federal, state, and local income tax and franchise tax (computed using simplifying assumptions to address the impact of state and local taxes) that the Company actually realizes (or is deemed to realize in certain circumstances) in periods after the IPO as a result, as applicable to each of the TRA Holders, of (i) certain increases in tax basis that occur as a result of the Company's acquisition (or deemed acquisition forU.S. federal income tax purposes) of all or a portion of such TRA Holders' Liberty LLC Units in connection with the IPO or pursuant to the exercise of the right of each Liberty Unit Holder (the "Redemption Right"), subject to certain limitations, to causeLiberty LLC to acquire all or a portion of its Liberty LLC Units for, atLiberty LLC's election, (A) shares of our Class A Common Stock at the specific redemption ratio or (B) an equivalent amount of cash, or, upon the exercise of the Redemption Right, the right ofLiberty Inc. (instead ofLiberty LLC ) to, for administrative convenience, acquire each tendered Liberty LLC Unit directly from the redeeming Liberty Unit Holder for, at its election, (1) one share of Class A Common Stock or (2) an equivalent amount of cash, (ii) any net operating losses available to the Company as a result of the Corporate Reorganization, and (iii) imputed interest deemed to be paid by the Company as a result of, and additional tax basis arising from, any payments the Company makes under the TRAs. With respect to obligations the Company expects to incur under the TRAs (except in cases where the Company elects to terminate the TRAs early, the TRAs are terminated early due to certain mergers, asset sales, or other changes of control, or the Company has available cash but fails to make payments when due), generally the Company may elect to defer payments due under the TRAs if the Company does not have available cash to satisfy its payment obligations under the TRAs or if its contractual obligations limit its ability to make such payments. Any such deferred payments under the TRAs generally will accrue interest. In certain cases, payments under the TRAs may be accelerated and/or significantly exceed the actual benefits, if any, the Company realizes in respect of the tax attributes subject to the TRAs. The Company accounts for amounts payable under the TRAs in accordance with ASC Topic 450, Contingencies. If the Company experiences a change of control (as defined under the TRAs) or the TRAs otherwise terminate early, the Company's obligations under the TRAs could have a substantial negative impact on its liquidity and could have the effect of 24 -------------------------------------------------------------------------------- Table of Contents delaying, deferring or preventing certain mergers, asset sales, or other forms of business combinations or changes of control. There can be no assurance that we will be able to finance our obligations under the TRAs. During the three months endedMarch 31, 2020 , there were no redemptions ofLiberty LLC units, which resulted in no increase in the amount payable under the TRAs. Critical Accounting Policies and Estimates The condensed consolidated financial statements are prepared in accordance with GAAP, which require us to make estimates and assumptions (see Note 2-Significant Accounting Policies to the consolidated and combined financial statements included in the Annual Report). We believe that some of our accounting policies involve a higher degree of judgment and complexity than others. As ofDecember 31, 2019 , our critical accounting policies included leases, revenue recognition, estimating the recoverability of accounts receivable, inventory valuation, accounting for income taxes, and accounting for long-lived assets. These critical accounting policies are discussed more fully in the Annual Report. EffectiveJanuary 1, 2020 , the Company adopted ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (see Note 2-Significant Accounting Policies to the condensed consolidated financial statements included in this Quarterly Report). There have been no other changes in our evaluation of our critical accounting policies sinceDecember 31, 2019 . Off Balance Sheet Arrangements We have no material off balance sheet arrangements as ofMarch 31, 2020 , except for purchase commitments under supply agreements as disclosed above under "Item 1. Financial Statements - Note 13-Commitments & Contingencies." As such, we are not materially exposed to any other financing, liquidity, market, or credit risk that could arise if we had engaged in such financing arrangements. 25
