EXXON MOBIL CORPORATION

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Basis of Financial Statement Preparation

These unaudited condensed consolidated financial statements should be read in the context of the consolidated financial statements and notes thereto filed with the Securities and Exchange Commission in the Corporation's 2020 Annual Report on Form 10-K. In the opinion of the Corporation, the information furnished herein reflects all known accruals and adjustments necessary for a fair statement of the results for the periods reported herein. All such adjustments are of a normal recurring nature. Prior data has been reclassified in certain cases to conform to the current presentation basis.

The Corporation's exploration and production activities are accounted for under the "successful efforts" method.

2. Miscellaneous Financial Information

Crude oil, products and merchandise inventories are carried at the lower of current market value or cost, generally determined under the last-in first-out method (LIFO). The Corporation's results for the second quarter of 2020 included a before-tax credit of $2,624 million, as rising prices reduced the charge against the book value of inventories from $2,777 million in the first quarter 2020 to $153 million for the first half of 2020. This adjustment, which is included in "Crude oil and product purchases", together with a market adjustment to inventory for equity companies included in "Income from equity affiliates", resulted in a $1,922 million after-tax credit to earnings (excluding noncontrolling interests) in the second quarter of 2020.

In the first half of 2020, mainly as a result of declines in prices for crude oil, natural gas and petroleum products and a significant decline in the Corporation's market capitalization at the end of the first quarter, before-tax goodwill impairment charges of $611 million and other impairment charges of $363 million were recognized. The charges related to goodwill impairments were included in “Depreciation and depletion” on the Statement of Income while the charges related to other impairments were largely included in “Income from equity affiliates.”

3. Litigation and Other Contingencies

Litigation. A variety of claims have been made against ExxonMobil and certain of its consolidated subsidiaries in a number of pending lawsuits. Management has regular litigation reviews, including updates from corporate and outside counsel, to assess the need for accounting recognition or disclosure of these contingencies. The Corporation accrues an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. The Corporation does not record liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated or when the liability is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is reasonably possible and which are significant, the Corporation discloses the nature of the contingency and, where feasible, an estimate of the possible loss. For purposes of our contingency disclosures, “significant” includes material matters, as well as other matters which management believes should be disclosed. ExxonMobil will continue to defend itself vigorously in these matters. Based on a consideration of all relevant facts and circumstances, the Corporation does not believe the ultimate outcome of any currently pending lawsuit against ExxonMobil will have a material adverse effect upon the Corporation's operations, financial condition, or financial statements taken as a whole.

Other Contingencies. The Corporation and certain of its consolidated subsidiaries were contingently liable at June 30, 2021, for guarantees relating to notes, loans and performance under contracts. Where guarantees for environmental remediation and other similar matters do not include a stated cap, the amounts reflect management’s estimate of the maximum potential exposure. These guarantees are not reasonably likely to have a material effect on the Corporation’s financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

		As of June 30, 2021
		Equity Company Obligations (1)	Other Third-Party Obligations	Total
		(millions of dollars)
Guarantees
	Debt-related	1,026	131	1,157
	Other	865	4,933	5,798
	Total	1,891	5,064	6,955

(1)ExxonMobil share

Additionally, the Corporation and its affiliates have numerous long-term sales and purchase commitments in their various business activities, all of which are expected to be fulfilled with no adverse consequences material to the Corporation’s operations or financial condition.

The operations and earnings of the Corporation and its affiliates throughout the world have been, and may in the future be, affected from time to time in varying degree by political developments and laws and regulations, such as forced divestiture of assets; restrictions on production, imports and exports; price controls; tax increases and retroactive tax claims; expropriation of property; cancellation of contract rights and environmental regulations. Both the likelihood of such occurrences and their overall effect upon the Corporation vary greatly from country to country and are not predictable.

In accordance with a Venezuelan nationalization decree issued in February 2007, a subsidiary of the Venezuelan National Oil Company (PdVSA) assumed the operatorship of the Cerro Negro Heavy Oil Project. The decree also required conversion of the Cerro Negro Project into a “mixed enterprise” and an increase in PdVSA’s or one of its affiliate’s ownership interest in the Project. ExxonMobil refused to accede to the terms proffered by the government, and on June 27, 2007, the government expropriated ExxonMobil’s 41.67 percent interest in the Cerro Negro Project.

ExxonMobil collected awards of $908 million in an arbitration against PdVSA under the rules of the International Chamber of Commerce in respect of an indemnity related to the Cerro Negro Project and $260 million in an arbitration for compensation due for the La Ceiba Project and for export curtailments at the Cerro Negro Project under rules of International Centre for Settlement of Investment Disputes (ICSID). An ICSID arbitration award relating to the Cerro Negro Project’s expropriation ($1.4 billion) was annulled based on a determination that a prior Tribunal failed to adequately explain why the cap on damages in the indemnity owed by PdVSA did not affect or limit the amount owed for the expropriation of the Cerro Negro Project. ExxonMobil filed a new claim seeking to restore the original award of damages for the Cerro Negro Project with ICSID on September 26, 2018.

The net impact of this matter on the Corporation’s consolidated financial results cannot be reasonably estimated. Regardless, the Corporation does not expect the resolution to have a material effect upon the Corporation’s operations or financial condition.

An affiliate of ExxonMobil is one of the Contractors under a Production Sharing Contract (PSC) with the Nigerian National Petroleum Corporation (NNPC) covering the Erha block located in the offshore waters of Nigeria. ExxonMobil's affiliate is the operator of the block and owns a 56.25 percent interest under the PSC. The Contractors are in dispute with NNPC regarding NNPC's lifting of crude oil in excess of its entitlement under the terms of the PSC. In accordance with the terms of the PSC, the Contractors initiated arbitration in Abuja, Nigeria, under the Nigerian Arbitration and Conciliation Act. On October 24, 2011, a three-member arbitral Tribunal issued an award upholding the Contractors' position in all material respects and awarding damages to the Contractors jointly in an amount of approximately $1.8 billion plus $234 million in accrued interest. The Contractors petitioned a Nigerian federal court for enforcement of the award, and NNPC petitioned the same court to have the award set aside. On May 22, 2012, the court set aside the award. The Contractors appealed that judgment to the Court of Appeal, Abuja Judicial Division. On July 22, 2016, the Court of Appeal upheld the decision of the lower court setting aside the award. On October 21, 2016, the Contractors appealed the decision to the Supreme Court of Nigeria. In June 2013, the Contractors filed a lawsuit against NNPC in the Nigerian federal high court in order to preserve their ability to seek enforcement of the PSC in the courts if necessary. Following dismissal by this court, the Contractors appealed to the Nigerian Court of Appeal in June 2016. In October 2014, the Contractors filed suit in the United States District Court for the Southern District of New York (SDNY) to enforce, if necessary, the arbitration award against NNPC assets residing within that jurisdiction. NNPC moved to dismiss the lawsuit. On September 4, 2019, the SDNY dismissed the Contractors’ petition to recognize and enforce the Erha arbitration award. The Contractors filed a notice of appeal in the Second Circuit on October 2, 2019. At this time, the net impact of this matter on the Corporation's consolidated financial results cannot be reasonably estimated. However, regardless of the outcome of enforcement proceedings, the Corporation does not expect the proceedings to have a material effect upon the Corporation's operations or financial condition.

At June 30, 2021, and December 31, 2020, respectively, the Corporation had $495 million and $504 million of collateral under master netting arrangements not offset against the derivatives on the Consolidated Balance Sheet, primarily related to initial margin requirements.

The Corporation may use non-derivative financial instruments, such as its foreign currency-denominated debt, as hedges of its net investments in certain foreign subsidiaries. Under this method, the change in the carrying value of the financial instruments due to foreign exchange fluctuations is reported in accumulated other comprehensive income. As of June 30, 2021, the Corporation has designated $5.3 billion of its Euro-denominated long-term debt and related accrued interest as a net investment hedge of its European business. The net investment hedge is deemed to be perfectly effective.

The Corporation had undrawn short-term committed lines of credit of $10.7 billion and undrawn long-term committed lines of credit of $0.6 billion as of second quarter 2021.

Derivative Instruments. The Corporation’s size, strong capital structure, geographic diversity and the complementary nature of the Upstream, Downstream and Chemical businesses reduce the Corporation’s enterprise-wide risk from changes in commodity prices, currency rates and interest rates. In addition, the Corporation uses commodity-based contracts, including derivatives, to manage commodity price risk and for trading purposes. Commodity contracts held for trading purposes are presented in the Consolidated Statement of Income on a net basis in the line “Sales and other operating revenue.” The Corporation’s commodity derivatives are not accounted for under hedge accounting. At times, the Corporation also enters into currency and interest rate derivatives, none of which are material to the Corporation’s financial position as of June 30, 2021, and December 31, 2020, or results of operations for the periods ended June 30, 2021, and 2020.

Credit risk associated with the Corporation’s derivative position is mitigated by several factors, including the use of derivative clearing exchanges and the quality of and financial limits placed on derivative counterparties. The Corporation maintains a system of controls that includes the authorization, reporting and monitoring of derivative activity.

The net notional long/(short) position of derivative instruments at June 30, 2021, and December 31, 2020, was as follows:

	June 30,	December 31,
	2021	2020

9. Divestment Activities

ExxonMobil signed an agreement in the first quarter of 2021 with HitecVision, through its wholly-owned portfolio company NEO Energy, for the sale of most of its non-operated upstream assets in the United Kingdom central and northern North Sea for more than $1 billion. The transaction is expected to close by year-end 2021, subject to standard conditions precedent, including regulatory and third-party approvals. The agreed sales price is subject to interim period adjustments from the effective date of January 1, 2021, to the closing date, and has an additional upside potential of approximately $0.3 billion in contingent payments, based on production levels and commodity prices. Estimated total cash flow from the divestment will range from $0.7 billion to $1.2 billion, of which $0.7 billion to $0.8 billion is expected in 2021 and the remainder in future years.

In the second quarter of 2021, ExxonMobil signed an agreement with Celanese for the sale of its global Santoprene business for $1.15 billion, subject to working capital and other adjustments. The sale includes two thermoplastic elastomers manufacturing sites in Pensacola, Florida and Newport, Wales along with associated assets. The transaction is expected to close in the fourth quarter of 2021, subject to standard conditions precedent including regulatory approvals. Estimated total cash flow from the divestment is approximately $0.9 billion.

The Corporation expects to recognize a gain at closing for each of these transactions. Estimated gain and net cash flow could change due to market factors, working capital adjustments, tax impacts, and closing dates.

10. Restructuring Activities

During 2020, ExxonMobil conducted an extensive global review of staffing levels and subsequently commenced targeted workforce reductions within a number of countries to improve efficiency and reduce costs. The programs, which are expected to be substantially completed by the end of 2021, include both voluntary and involuntary employee separations and reductions in contractors.

During the second quarter of 2021, the Corporation recorded before-tax charges of $10 million, consisting primarily of employee separation costs, from workforce reductions in Singapore and Europe associated with the global review of staffing levels. These costs are captured in “Selling, general and administrative expenses” on the Statement of Income.

For the first six months of the year, the recorded before-tax charges associated with the global review of staffing levels were $49 million.

For the full year, the Corporation estimates charges of less than $100 million related to planned workforce reduction programs associated with the global review of staffing levels. This does not include charges related to employee reductions associated with any portfolio changes or other projects.

The following tables summarize the reserves and charges related to the workforce reduction programs associated with the global review of staffing levels, which are recorded in “Accounts payable and accrued liabilities.”

EXXON MOBIL CORPORATION

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

In early 2020, the balance of supply and demand for petroleum and petrochemical products experienced two significant disruptive effects. On the demand side, the COVID-19 pandemic spread rapidly through most areas of the world resulting in substantial reductions in consumer and business activity and significantly reduced demand for crude oil, natural gas, and petroleum products. This reduction in demand coincided with announcements of increased production in certain key oil-producing countries which led to increases in inventory levels and sharp declines in prices for crude oil, natural gas, and petroleum products.

Demand for petroleum and petrochemical products has continued to recover through 2021 with the Corporation's second quarter 2021 financial results benefiting from stronger prices and margins when compared to the first quarter of 2021. The rate and pace of recovery, however, has varied across geographies and business lines, with Downstream margins remaining low compared to historical levels over the last decade. The Corporation continues to closely monitor industry and economic conditions amid the uneven global recovery from the COVID-19 pandemic.

REVIEW OF SECOND QUARTER 2021 RESULTS

ExxonMobil’s second quarter 2021 earnings were $4.7 billion, or $1.10 per diluted share, compared with a loss of $1.1 billion a year earlier. The increase in earnings was driven by higher Upstream realizations; higher Chemical and Downstream margins; higher volumes; and lower expenses. These impacts were partly offset by the absence of prior year favorable non-operational inventory adjustments and higher scheduled maintenance activity.

Earnings for the first six months of 2021 were $7.4 billion, or $1.74 per diluted share, compared with a loss of $1.7 billion a year earlier.

Capital and exploration expenditures were $6.9 billion, down $5.5 billion from 2020.

Oil-equivalent production was 3.7 million barrels per day, down 4 percent from the prior year. Excluding entitlement effects, divestments, and government mandates, oil-equivalent production was up 1 percent from the prior year.

The Corporation distributed $7.4 billion in dividends to shareholders.

Upstream earnings were $3,185 million in the second quarter of 2021, compared with a loss of $1,651 million in the second quarter of 2020.

•Realizations increased earnings by $4,320 million, driven by higher liquids realizations of $4,060 million and higher gas realizations of $260 million.

•Volume and mix effects increased earnings by $40 million due to favorable liquids sales mix of $30 million and higher gas sales volumes of $10 million.

•All other items increased earnings by $470 million, as lower expenses of $280 million and favorable other earnings impacts of $270 million were partly offset by unfavorable foreign exchange impacts of $80 million.

•U.S. Upstream earnings were $663 million, up $1,860 million from the prior year quarter.

•Non-U.S. Upstream earnings were $2,522 million, up $2,976 million from the prior year quarter.

•On an oil-equivalent basis, production decreased 2 percent from the second quarter of 2020.

•Liquids production totaled 2.2 million barrels per day, down 106,000 barrels per day, as higher demand was more than offset by lower entitlements and increased maintenance activity.

•Natural gas production was 8.3 billion cubic feet per day, up 304 million cubic feet per day, reflecting the impacts of higher demand partly offset by increased maintenance activity and divestments.

Upstream earnings were $5,739 million in the first six months of 2021, compared with a loss of $1,115 million in the first six months of 2020.

•Realizations increased earnings by $5,610 million, with higher liquids realizations of $5,450 million and higher gas realizations of $160 million.

•Volume and mix effects reduced earnings by $320 million, reflecting lower liquid sales volumes of $370 million partly offset by higher gas volumes of $50 million.

•All other items increased earnings by $1,560 million, as lower expenses of $990 million and the absence of prior year unfavorable non-operational impacts of $410 million and other favorable earnings impacts of $460 million were partly offset by unfavorable foreign exchange effects of $300 million.

•U.S. Upstream earnings were $1,026 million, compared with a loss of $1,901 million in the prior year.

•Non-U.S. Upstream earnings were $4,713 million, up $3,927 million from the prior year.

•On an oil-equivalent basis, production decreased 4 percent from the first six months of 2020.

•Liquids production totaled 2.2 million barrels per day, down 164,000 barrels per day, with higher demand and project growth more than offset by lower entitlements, government mandates, decline and increased maintenance activity.

•Natural gas production was 8.7 billion cubic feet per day, up 38 million cubic feet per day, as higher demand was largely offset by increased maintenance activity, the Groningen production limit, and divestments.

(1)Natural gas is converted to an oil-equivalent basis at six million cubic feet per one thousand barrels.

Listed below are descriptions of ExxonMobil’s volumes reconciliation factors which are provided to facilitate understanding of the terms.

Entitlements - Net Interest are changes to ExxonMobil’s share of production volumes caused by non-operational changes to volume-determining factors. These factors consist of net interest changes specified in Production Sharing Contracts (PSCs) which typically occur when cumulative investment returns or production volumes achieve defined thresholds, changes in equity upon achieving pay-out in partner investment carry situations, equity redeterminations as specified in venture agreements, or as a result of the termination or expiry of a concession. Once a net interest change has occurred, it typically will not be reversed by subsequent events, such as lower crude oil prices.

Entitlements - Price, Spend and Other are changes to ExxonMobil’s share of production volumes resulting from temporary changes to non-operational volume-determining factors. These factors include changes in oil and gas prices or spending levels from one period to another. According to the terms of contractual arrangements or government royalty regimes, price or spending variability can increase or decrease royalty burdens and/or volumes attributable to ExxonMobil. For example, at higher prices, fewer barrels are required for ExxonMobil to recover its costs. These effects generally vary from period to period with field spending patterns or market prices for oil and natural gas. Such factors can also include other temporary changes in net interest as dictated by specific provisions in production agreements.

Government Mandates are changes to ExxonMobil's sustainable production levels due to temporary non-operational production limits imposed by governments, generally upon a sector, type or method of production.

Divestments are reductions in ExxonMobil’s production arising from commercial arrangements to fully or partially reduce equity in a field or asset in exchange for financial or other economic consideration.

Growth and Other factors comprise all other operational and non-operational factors not covered by the above definitions that may affect volumes attributable to ExxonMobil. Such factors include, but are not limited to, production enhancements from project and work program activities, acquisitions including additions from asset exchanges, downtime, market demand, natural field decline, and any fiscal or commercial terms that do not affect entitlements.

Downstream results were a loss of $227 million in the second quarter of 2021, down $1,203 million from the second quarter of 2020.

•Margins increased earnings by $430 million, reflecting stronger industry refining conditions.

•Volume and mix effects increased earnings by $220 million.

•All other items decreased earnings by $1,860 million, reflecting the absence of a prior year favorable inventory adjustment of $1,590 million, unfavorable foreign exchange impacts of $90 million, higher expenses of $60 million, and other unfavorable earnings impacts of $120 million.

Cash flow from operations and asset sales	9,900	43	19,471	6,403

Because of the ongoing nature of our asset management and divestment program, we believe it is useful for investors to consider proceeds associated with asset sales together with cash provided by operating activities when evaluating cash available for investment in the business and financing activities, including shareholder distributions.

Cash flow from operations and asset sales in the second quarter of 2021 was $9.9 billion, an increase of $9.9 billion from the comparable 2020 period primarily reflecting higher earnings and more favorable working capital impacts.

Cash provided by operating activities totaled $18.9 billion for the first six months of 2021, $12.6 billion higher than 2020. Net income including noncontrolling interests was $7.6 billion, an increase of $9.5 billion from the prior year period. The adjustments for the noncash provision of $10.0 billion for depreciation and depletion was down $0.8 billion from 2020. Changes in operational working capital were a contribution of $1.6 billion, compared to a reduction of $2.2 billion in the prior year period. All other items net decreased cash flows by $0.2 billion in 2021 versus a reduction of $0.3 billion in 2020. See the Condensed Consolidated Statement of Cash Flows for additional details.

Investing activities for the first six months of 2021 used net cash of $5.1 billion, a decrease of $6.4 billion compared to the prior year. Spending for additions to property, plant and equipment of $5.1 billion was $5.2 billion lower than 2020. Proceeds from asset sales of $0.6 billion were $0.4 billion higher than the prior year. Net investments and advances decreased $0.7 billion to $0.5 billion.

Net cash used by financing activities was $14.8 billion in the first six months of 2021, including $7.0 billion of debt repayments. This compares to net cash provided by financing activities of $15.1 billion in the prior year, due to long-term debt issuances in the first six months of 2020.

Total debt at the end of the second quarter of 2021 was $60.6 billion compared to $67.6 billion at year-end 2020. The Corporation's debt to total capital ratio was 26.8 percent at the end of the second quarter of 2021 compared to 29.2 percent at year-end 2020. The Corporation's capital allocation priorities continue to be investing in advantaged projects, strengthening the balance sheet and paying a reliable dividend.

The Corporation has access to significant capacity of long-term and short-term liquidity. Commercial paper continues to provide short-term liquidity, and is reflected in "Notes and loans payable" on the Consolidated Balance Sheet. Cash and cash equivalents was $3.5 billion at the end of the second quarter of 2021. The Corporation had undrawn short-term committed lines of credit of $10.7 billion and undrawn long-term committed lines of credit of $0.6 billion as of second quarter 2021.

The Corporation distributed a total of $7.4 billion to shareholders in the first six months of 2021 through dividends.

The Corporation, as part of its ongoing asset management program, continues to evaluate its mix of assets for potential upgrade. Because of the ongoing nature of this program, dispositions will continue to be made from time to time which will result in either gains or losses. Additionally, the Corporation continues to evaluate opportunities to enhance its business portfolio through acquisitions of assets or companies, and enters into such transactions from time to time. Key criteria for evaluating acquisitions include potential for future growth and attractive current valuations. Acquisitions may be made with cash, shares of the Corporation’s common stock, or both.

25

The termination of certain transportation service agreements in the first quarter reduced commitments previously reported at year-end in Form 10-K under “Take-or-pay and unconditional purchase obligations” by approximately $2.3 billion. The majority of those commitments related to the years 2026 and beyond.

Litigation and other contingencies are discussed in Note 3 to the unaudited condensed consolidated financial statements.

TAXES

	Second Quarter				First Six Months
	2021		2020		2021		2020
	(millions of dollars)				(millions of dollars)
Income taxes	1,526		(471)		2,322		41
Effective income tax rate	30	%	29	%	31	%	-33	%
Total other taxes and duties (1)	8,441		5,683		15,724		13,180
Total	9,967		5,212		18,046		13,221

(1)Includes “Other taxes and duties” plus taxes that are included in “Production and manufacturing expenses” and “Selling, general and administrative expenses.”

Total taxes were $10.0 billion for the second quarter of 2021, an increase of $4.8 billion from 2020. Income tax expense was $1.5 billion compared to a $0.5 billion income tax credit in the prior year reflecting higher commodity prices. The effective income tax rate of 30 percent compared to 29 percent in the prior year period primarily due to a change in mix of results in jurisdictions with varying tax rates. Total other taxes and duties increased by $2.8 billion to $8.4 billion.

Total taxes were $18.0 billion for the first six months of 2021, an increase of $4.8 billion from 2020. Income tax expense increased by $2.3 billion to $2.3 billion reflecting higher commodity prices. The effective income tax rate of 31 percent compared to -33 percent in the prior year period primarily due to a change in mix of results in jurisdictions with varying tax rates. Total other taxes and duties increased by $2.5 billion to $15.7 billion.

In the United States, the Corporation has various ongoing U.S. federal income tax positions at issue with the Internal Revenue Service (IRS) for tax years beginning in 2006. The Corporation filed a refund suit for tax years 2006-2009 in U.S. federal district court (District Court) with respect to the positions at issue for those years. On February 24, 2020, the Corporation received an adverse ruling on this suit. The IRS has asserted penalties associated with several of those positions. The Corporation has not recognized the penalties as an expense because the Corporation does not expect the penalties to be sustained under applicable law. On January 13, 2021, the District Court ruled that no penalties apply to the Corporation's positions in this suit. The Corporation filed a notice of appeal regarding the substantive issues to the Fifth Circuit Court of Appeals on April 9, 2021. The government filed a notice of appeal regarding the penalty issue to the same court on April 19, 2021. Proceedings in the Fifth Circuit Court of Appeals are continuing. Unfavorable resolution of all positions at issue with the IRS would not have a material adverse effect on the Corporation’s operations or financial condition.

RESTRUCTURING ACTIVITIES

During 2020, ExxonMobil conducted an extensive global review of staffing levels and subsequently commenced targeted workforce reductions within a number of countries to improve efficiency and reduce costs. The programs, which are expected to be substantially complete by the end of 2021, include both voluntary and involuntary employee separations and reductions in contractors.

In the first half of 2021, the Corporation recorded after-tax charges of $43 million, consisting primarily of employee separation costs, from workforce reduction programs in Singapore and Europe associated with the global review of staffing levels. The cash outflows in the first half of 2021 associated with these activities were $224 million.

The Corporation estimates total charges of less than $100 million in 2021 related to planned workforce reduction programs with cash outflows ranging between $400 million and $500 million. This does not include charges related to employee reductions associated with any portfolio changes or other projects. Before-tax workforce reduction savings, including employees and contractors, are estimated to range between $1 billion and $2 billion per year after program completion when compared to 2019 levels.

	2021	2020	2021	2020
	(millions of dollars)		(millions of dollars)
Upstream (including exploration expenses)	2,817	3,577	5,174	8,703
Downstream	455	1,053	925	2,287
Chemical	530	695	836	1,477
Other	1	2	1	3
Total	3,803	5,327	6,936	12,470

Capital and exploration expenditures in the second quarter of 2021 were $3.8 billion, down 29 percent from the second quarter of 2020.

Capital and exploration expenditures in the first six months of 2021 were $6.9 billion, down 44 percent from the first six months of 2020. The Corporation expects 2021 capital spending to be toward the lower end of the guidance range of $16 billion to $19 billion. Actual spending could vary depending on the progress of individual projects and property acquisitions. If market conditions continue above the Corporation's planning basis, additional cash will not be used to increase capital investment above this range, but will instead be used to accelerate deleveraging.

FORWARD-LOOKING STATEMENTS

Actual future results, including financial and operating performance; total capital expenditures and mix; cost and expense reductions; emissions intensity and absolute emission reductions; cash flow, dividends, debt levels, and shareholder returns; business and project plans, timing, costs, capacities, and returns; asset management activities; results from settlement of outstanding derivatives; workforce reductions; the outcome of litigation, tax, and other contingencies; and future accounting and financial reporting effects of the foregoing could differ materially due to a number of factors. These include global or regional changes in the supply and demand for oil, natural gas, petrochemicals, and feedstocks and other market conditions that impact prices and differentials; actions of competitors and commercial counterparties; the ability to access short- and long-term debt markets on a timely and affordable basis; the ultimate impacts of COVID-19, including the extent and nature of further outbreaks and the effects of government responses on people and economies; reservoir performance; the outcome of exploration projects; timely completion of development and other construction projects; changes in law, taxes, or regulation including environmental regulations, trade sanctions, and timely granting of governmental permits; government policies and support and market demand for low carbon technologies like carbon capture; war, and other political or security disturbances; opportunities for potential investments or divestments and satisfaction of applicable conditions to closing, including regulatory approvals; the capture of efficiencies within and between business lines and the ability to maintain near-term cost reductions as ongoing efficiencies while maintaining future competitive positioning; unforeseen technical or operating difficulties and unplanned maintenance; the development and competitiveness of alternative energy and emission reduction technologies; the results of research programs and the ability to bring new technologies to commercial scale on a cost-competitive basis; and other factors discussed in this report and under Item 1A. Risk Factors of ExxonMobil’s 2020 Form 10-K. We assume no duty to update these statements as of any future date.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Information about market risks for the six months ended June 30, 2021, does not differ materially from that discussed under Item 7A of the registrant's Annual Report on Form 10-K for 2020.

Item 4. Controls and Procedures

As indicated in the certifications in Exhibit 31 of this report, the Corporation’s Chief Executive Officer, Principal Financial Officer and Principal Accounting Officer have evaluated the Corporation’s disclosure controls and procedures as of June 30, 2021. Based on that evaluation, these officers have concluded that the Corporation’s disclosure controls and procedures are effective in ensuring that information required to be disclosed by the Corporation in the reports that it files or submits under the Securities Exchange Act of 1934, as amended, is accumulated and communicated to them in a manner that allows for timely decisions regarding required disclosures and are effective in ensuring that such information is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. There were no changes during the Corporation’s last fiscal quarter that materially affected, or are reasonably likely to materially affect, the Corporation’s internal control over financial reporting.

Miscellaneous Financial Information

Miscellaneous Financial Information

Crude oil, products and merchandise inventories are carried at the lower of current market value or cost, generally determined under the last-in first-out method (LIFO). The Corporation's results for the second quarter of 2020 included a before-tax credit of $2,624 million, as rising prices reduced the charge against the book value of inventories from $2,777 million in the first quarter 2020 to $153 million for the first half of 2020. This adjustment, which is included in "Crude oil and product purchases", together with a market adjustment to inventory for equity companies included in "Income from equity affiliates", resulted in a $1,922 million after-tax credit to earnings (excluding noncontrolling interests) in the second quarter of 2020.

In the first half of 2020, mainly as a result of declines in prices for crude oil, natural gas and petroleum products and a significant decline in the Corporation's market capitalization at the end of the first quarter, before-tax goodwill impairment charges of $611 million and other impairment charges of $363 million were recognized. The charges related to goodwill impairments were included in “Depreciation and depletion” on the Statement of Income while the charges related to other impairments were largely included in “Income from equity affiliates.”

Loss Contingency [Abstract]

Litigation And Other Contingencies

Litigation and Other Contingencies

Litigation. A variety of claims have been made against ExxonMobil and certain of its consolidated subsidiaries in a number of pending lawsuits. Management has regular litigation reviews, including updates from corporate and outside counsel, to assess the need for accounting recognition or disclosure of these contingencies. The Corporation accrues an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. The Corporation does not record liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated or when the liability is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is reasonably possible and which are significant, the Corporation discloses the nature of the contingency and, where feasible, an estimate of the possible loss. For purposes of our contingency disclosures, “significant” includes material matters, as well as other matters which management believes should be disclosed. ExxonMobil will continue to defend itself vigorously in these matters. Based on a consideration of all relevant facts and circumstances, the Corporation does not believe the ultimate outcome of any currently pending lawsuit against ExxonMobil will have a material adverse effect upon the Corporation's operations, financial condition, or financial statements taken as a whole.

Other Contingencies. The Corporation and certain of its consolidated subsidiaries were contingently liable at June 30, 2021, for guarantees relating to notes, loans and performance under contracts. Where guarantees for environmental remediation and other similar matters do not include a stated cap, the amounts reflect management’s estimate of the maximum potential exposure. These guarantees are not reasonably likely to have a material effect on the Corporation’s financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

(1)ExxonMobil share

Additionally, the Corporation and its affiliates have numerous long-term sales and purchase commitments in their various business activities, all of which are expected to be fulfilled with no adverse consequences material to the Corporation’s operations or financial condition.

The operations and earnings of the Corporation and its affiliates throughout the world have been, and may in the future be, affected from time to time in varying degree by political developments and laws and regulations, such as forced divestiture of assets; restrictions on production, imports and exports; price controls; tax increases and retroactive tax claims; expropriation of property; cancellation of contract rights and environmental regulations. Both the likelihood of such occurrences and their overall effect upon the Corporation vary greatly from country to country and are not predictable.

In accordance with a Venezuelan nationalization decree issued in February 2007, a subsidiary of the Venezuelan National Oil Company (PdVSA) assumed the operatorship of the Cerro Negro Heavy Oil Project. The decree also required conversion of the Cerro Negro Project into a “mixed enterprise” and an increase in PdVSA’s or one of its affiliate’s ownership interest in the Project. ExxonMobil refused to accede to the terms proffered by the government, and on June 27, 2007, the government expropriated ExxonMobil’s 41.67 percent interest in the Cerro Negro Project.

ExxonMobil collected awards of $908 million in an arbitration against PdVSA under the rules of the International Chamber of Commerce in respect of an indemnity related to the Cerro Negro Project and $260 million in an arbitration for compensation due for the La Ceiba Project and for export curtailments at the Cerro Negro Project under rules of International Centre for Settlement of Investment Disputes (ICSID). An ICSID arbitration award relating to the Cerro Negro Project’s expropriation ($1.4 billion) was annulled based on a determination that a prior Tribunal failed to adequately explain why the cap on damages in the indemnity owed by PdVSA did not affect or limit the amount owed for the expropriation of the Cerro Negro Project. ExxonMobil filed a new claim seeking to restore the original award of damages for the Cerro Negro Project with ICSID on September 26, 2018.

The net impact of this matter on the Corporation’s consolidated financial results cannot be reasonably estimated. Regardless, the Corporation does not expect the resolution to have a material effect upon the Corporation’s operations or financial condition.

An affiliate of ExxonMobil is one of the Contractors under a Production Sharing Contract (PSC) with the Nigerian National Petroleum Corporation (NNPC) covering the Erha block located in the offshore waters of Nigeria. ExxonMobil's affiliate is the operator of the block and owns a 56.25 percent interest under the PSC. The Contractors are in dispute with NNPC regarding NNPC's lifting of crude oil in excess of its entitlement under the terms of the PSC. In accordance with the terms of the PSC, the Contractors initiated arbitration in Abuja, Nigeria, under the Nigerian Arbitration and Conciliation Act. On October 24, 2011, a three-member arbitral Tribunal issued an award upholding the Contractors' position in all material respects and awarding damages to the Contractors jointly in an amount of approximately $1.8 billion plus $234 million in accrued interest. The Contractors petitioned a Nigerian federal court for enforcement of the award, and NNPC petitioned the same court to have the award set aside. On May 22, 2012, the court set aside the award. The Contractors appealed that judgment to the Court of Appeal, Abuja Judicial Division. On July 22, 2016, the Court of Appeal upheld the decision of the lower court setting aside the award. On October 21, 2016, the Contractors appealed the decision to the Supreme Court of Nigeria. In June 2013, the Contractors filed a lawsuit against NNPC in the Nigerian federal high court in order to preserve their ability to seek enforcement of the PSC in the courts if necessary. Following dismissal by this court, the Contractors appealed to the Nigerian Court of Appeal in June 2016. In October 2014, the Contractors filed suit in the United States District Court for the Southern District of New York (SDNY) to enforce, if necessary, the arbitration award against NNPC assets residing within that jurisdiction. NNPC moved to dismiss the lawsuit. On September 4, 2019, the SDNY dismissed the Contractors’ petition to recognize and enforce the Erha arbitration award. The Contractors filed a notice of appeal in the Second Circuit on October 2, 2019. At this time, the net impact of this matter on the Corporation's consolidated financial results cannot be reasonably estimated. However, regardless of the outcome of enforcement proceedings, the Corporation does not expect the proceedings to have a material effect upon the Corporation's operations or financial condition.

(4)Included in the Balance Sheet lines: Accounts payable and accrued liabilities and Other long-term obligations

(5)Excluding finance lease obligations

(6)Advances to/receivables from equity companies and long-term obligations to equity companies are mainly designated as hierarchy level 3 inputs. The fair value is calculated by discounting the remaining obligations by a rate consistent with the credit quality and industry of the company.

(7)Included in the Balance Sheet line: Other long-term obligations. Includes contingent consideration related to a prior year acquisition where fair value is based on expected drilling activities and discount rates.

At June 30, 2021, and December 31, 2020, respectively, the Corporation had $495 million and $504 million of collateral under master netting arrangements not offset against the derivatives on the Consolidated Balance Sheet, primarily related to initial margin requirements.

The Corporation may use non-derivative financial instruments, such as its foreign currency-denominated debt, as hedges of its net investments in certain foreign subsidiaries. Under this method, the change in the carrying value of the financial instruments due to foreign exchange fluctuations is reported in accumulated other comprehensive income. As of June 30, 2021, the Corporation has designated $5.3 billion of its Euro-denominated long-term debt and related accrued interest as a net investment hedge of its European business. The net investment hedge is deemed to be perfectly effective.

The Corporation had undrawn short-term committed lines of credit of $10.7 billion and undrawn long-term committed lines of credit of $0.6 billion as of second quarter 2021.

Derivative Instruments. The Corporation’s size, strong capital structure, geographic diversity and the complementary nature of the Upstream, Downstream and Chemical businesses reduce the Corporation’s enterprise-wide risk from changes in commodity prices, currency rates and interest rates. In addition, the Corporation uses commodity-based contracts, including derivatives, to manage commodity price risk and for trading purposes. Commodity contracts held for trading purposes are presented in the Consolidated Statement of Income on a net basis in the line “Sales and other operating revenue.” The Corporation’s commodity derivatives are not accounted for under hedge accounting. At times, the Corporation also enters into currency and interest rate derivatives, none of which are material to the Corporation’s financial position as of June 30, 2021, and December 31, 2020, or results of operations for the periods ended June 30, 2021, and 2020.

Credit risk associated with the Corporation’s derivative position is mitigated by several factors, including the use of derivative clearing exchanges and the quality of and financial limits placed on derivative counterparties. The Corporation maintains a system of controls that includes the authorization, reporting and monitoring of derivative activity.

The net notional long/(short) position of derivative instruments at June 30, 2021, and December 31, 2020, was as follows:

	June 30,	December 31,
	2021	2020
	(millions)
Crude oil (barrels)	30	40
Petroleum products (barrels)	(69)	(46)

Divestment Activities

Divestment Activities

ExxonMobil signed an agreement in the first quarter of 2021 with HitecVision, through its wholly-owned portfolio company NEO Energy, for the sale of most of its non-operated upstream assets in the United Kingdom central and northern North Sea for more than $1 billion. The transaction is expected to close by year-end 2021, subject to standard conditions precedent, including regulatory and third-party approvals. The agreed sales price is subject to interim period adjustments from the effective date of January 1, 2021, to the closing date, and has an additional upside potential of approximately $0.3 billion in contingent payments, based on production levels and commodity prices. Estimated total cash flow from the divestment will range from $0.7 billion to $1.2 billion, of which $0.7 billion to $0.8 billion is expected in 2021 and the remainder in future years.

In the second quarter of 2021, ExxonMobil signed an agreement with Celanese for the sale of its global Santoprene business for $1.15 billion, subject to working capital and other adjustments. The sale includes two thermoplastic elastomers manufacturing sites in Pensacola, Florida and Newport, Wales along with associated assets. The transaction is expected to close in the fourth quarter of 2021, subject to standard conditions precedent including regulatory approvals. Estimated total cash flow from the divestment is approximately $0.9 billion.

The Corporation expects to recognize a gain at closing for each of these transactions. Estimated gain and net cash flow could change due to market factors, working capital adjustments, tax impacts, and closing dates.

Restructuring Activities

Restructuring Activities

During 2020, ExxonMobil conducted an extensive global review of staffing levels and subsequently commenced targeted workforce reductions within a number of countries to improve efficiency and reduce costs. The programs, which are expected to be substantially completed by the end of 2021, include both voluntary and involuntary employee separations and reductions in contractors.

During the second quarter of 2021, the Corporation recorded before-tax charges of $10 million, consisting primarily of employee separation costs, from workforce reductions in Singapore and Europe associated with the global review of staffing levels. These costs are captured in “Selling, general and administrative expenses” on the Statement of Income.

For the first six months of the year, the recorded before-tax charges associated with the global review of staffing levels were $49 million.

For the full year, the Corporation estimates charges of less than $100 million related to planned workforce reduction programs associated with the global review of staffing levels. This does not include charges related to employee reductions associated with any portfolio changes or other projects.

The following tables summarize the reserves and charges related to the workforce reduction programs associated with the global review of staffing levels, which are recorded in “Accounts payable and accrued liabilities.”

Summary of Accounting Policies (Policy)	6 Months Ended
	Jun. 30, 2021
Accounting Policies [Abstract]
Inventory Policy	Crude oil, products and merchandise inventories are carried at the lower of current market value or cost, generally determined under the last-in first-out method (LIFO).
Legal Costs Policy	The Corporation accrues an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. The Corporation does not record liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated or when the liability is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is reasonably possible and which are significant, the Corporation discloses the nature of the contingency and, where feasible, an estimate of the possible loss. For purposes of our contingency disclosures, “significant” includes material matters, as well as other matters which management believes should be disclosed.
Net Investment Hedge Risk Management Policy	The Corporation may use non-derivative financial instruments, such as its foreign currency-denominated debt, as hedges of its net investments in certain foreign subsidiaries. Under this method, the change in the carrying value of the financial instruments due to foreign exchange fluctuations is reported in accumulated other comprehensive income.
