PEABODY ENERGY CORPORATION
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(1) Basis of Presentation
The condensed consolidated financial statements include the accounts of Peabody Energy Corporation (PEC) and its consolidated subsidiaries and affiliates (along with PEC, the Company or Peabody). Interests in subsidiaries controlled by the Company are consolidated with any outside stockholder interests reflected as noncontrolling interests, except when the Company has an undivided interest in a joint venture. In those cases, the Company includes its proportionate share in the assets, liabilities, revenues and expenses of the jointly controlled entities within each applicable line item of the unaudited condensed consolidated financial statements. All intercompany transactions, profits and balances have been eliminated in consolidation.
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements and should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. In the opinion of management, these financial statements reflect all normal, recurring adjustments necessary for a fair presentation. Balance sheet information presented herein as of December 31, 2020 has been derived from the Company’s audited consolidated balance sheet at that date. The Company’s results of operations for the three and six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for future quarters or for the year ending December 31, 2021.
(2) Newly Adopted Accounting Standards and Accounting Standards Not Yet Implemented
Newly Adopted Accounting Standards
Equity Method Investments. In January 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-01, which clarifies the interactions between Accounting Standards Codification (ASC) 321, ASC 323 and ASC 815. The new guidance addresses accounting for the transition into and out of the equity method and measuring certain purchased options and forward contracts to acquire investments. ASU 2020-01 is effective on January 1, 2021 for calendar year-end public companies. The Company adopted the requirements effective January 1, 2021. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements or disclosures.
Accounting Standards Not Yet Implemented
Reference Rate Reform. In March 2020, ASU 2020-04 was issued, which provides optional guidance for a limited period of time to ease the potential burden on accounting for contract modifications caused by reference rate reform (including reform of the London Interbank Offered Rate (LIBOR) or other reference rate reform). This guidance is effective for all entities as of March 12, 2020 through December 31, 2022. The guidance may be adopted over time as reference rate reform activities occur and should be applied on a prospective basis. The Company is still completing its evaluation of the impact of the guidance and plans to elect optional expedients as reference rate reform activities occur. The Company does not expect the guidance to have a material impact on its consolidated financial statements or disclosures.
(3) Revenue Recognition
Refer to Note 1. “Summary of Significant Accounting Policies” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020, for the Company’s policies regarding “Revenues” and “Accounts receivable, net.”

(1) Corporate and Other revenue includes gains and losses related to mark-to-market adjustments from economic hedge activities intended to hedge future coal sales. Refer to Note 7. “Derivatives and Fair Value Measurements” for additional information regarding the economic hedge activities.
(2) Other includes revenues from arrangements such as customer contract-related payments associated with volume shortfalls, royalties related to coal lease agreements, sales agency commissions, farm income and property and facility rentals.
Committed Revenue from Contracts with Customers
The Company expects to recognize revenue subsequent to June 30, 2021 of approximately $3.6 billion related to contracts with customers in which volumes and prices per ton were fixed or reasonably estimable at June 30, 2021. Approximately 46% of such amount is expected to be recognized over the next twelve months and the remainder thereafter. Actual revenue related to such contracts may differ materially for various reasons, including price adjustment features for coal quality and cost escalations, volume optionality provisions and potential force majeure events. This estimate of future revenue does not include any revenue related to contracts with variable prices per ton that cannot be reasonably estimated, such as the majority of seaborne metallurgical and seaborne thermal coal contracts where pricing is negotiated or settled quarterly or annually.
Accounts Receivable
“Accounts receivable, net” at June 30, 2021 and December 31, 2020 consisted of the following:

| June 30, 2021 |  | December 31, 2020
| (Dollars in millions)
Trade receivables, net | $ | 217.3 |  |  | $ | 180.9 |
Miscellaneous receivables, net | 33.4 |  |  | 63.9 |

Total liabilities classified as discontinued operations | $ | 147.9 |  |  | $ | 153.7 |

Patriot-Related Matters
A significant portion of the liabilities in the table above relate to Patriot. In 2012, Patriot filed voluntary petitions for relief under Chapter 11 of Title 11 of the U.S. Code (the Bankruptcy Code). In 2013, the Company entered into a definitive settlement agreement (2013 Agreement) with Patriot and the United Mine Workers of America (UMWA), on behalf of itself, its represented Patriot employees and its represented Patriot retirees, to resolve all then-disputed issues related to Patriot’s bankruptcy. In May 2015, Patriot again filed voluntary petitions for relief under the Bankruptcy Code in the U.S. District Court for the Eastern District of Virginia and subsequently initiated a process to sell substantially all of its assets to qualified bidders. On October 9, 2015, Patriot’s bankruptcy court entered an order confirming Patriot’s plan of reorganization, which provided, among other things, for the sale of substantially all of Patriot’s assets to two different buyers.
Black Lung Occupational Disease Liabilities. Patriot had federal and state black lung occupational disease liabilities related to workers employed in periods prior to Patriot’s spin-off from the Company in 2007. Upon spin-off, Patriot indemnified the Company against any claim relating to these liabilities, which amounted to approximately $150 million at that time. The indemnification included any claim made by the U.S. Department of Labor (DOL) against the Company with respect to these obligations as a potentially liable operator under the Federal Coal Mine Health and Safety Act of 1969. The 2013 Agreement included Patriot’s affirmance of indemnities provided in the spin-off agreements, including the indemnity relating to such black lung liabilities; however, Patriot rejected this indemnity in its May 2015 bankruptcy.
By statute, the Company had secondary liability for the black lung liabilities related to Patriot’s workers employed by former subsidiaries of the Company. The Company’s accounting for the black lung liabilities related to Patriot is based on an interpretation of applicable statutes. Management believes that inconsistencies exist among the applicable statutes, regulations promulgated under those statutes and the DOL’s interpretative guidance. The Company has sought clarification from the DOL regarding these inconsistencies. The amount of these liabilities could be reduced in the future. Whether the Company will ultimately be required to fund certain of those obligations in the future as a result of Patriot’s May 2015 bankruptcy remains uncertain. The amount of the liability, which was determined on an actuarial basis based on the best information available to the Company, was $89.7 million and $90.1 million at June 30, 2021 and December 31, 2020, respectively. While the Company has recorded a liability, it intends to review each claim on a case-by-case basis and contest liability estimates as appropriate. The amount of the Company’s recorded liability reflects only Patriot workers employed by former subsidiaries of the Company that are presently retired, disabled or otherwise not actively employed. The Company cannot reliably estimate the potential liabilities for Patriot’s workers employed by former subsidiaries of the Company that are presently active in the workforce because of the potential for such workers to continue to work for another coal operator that is a going concern.

(6) Equity Method Investments
The Company had total equity method investments and financing receivables of $17.5 million and $24.6 million reflected in “Investments and other assets” in the condensed consolidated balance sheets as of June 30, 2021 and December 31, 2020, respectively, related to Middlemount Coal Pty Ltd (Middlemount). Included in “Loss from equity affiliates” in the unaudited condensed consolidated statements of operations were losses related to Middlemount of $3.5 million and $4.4 million during the three and six months ended June 30, 2021, respectively, and losses of $6.0 million and $15.1 million during the three and six months ended June 30, 2020, respectively.
The Company received cash payments from Middlemount of $2.3 million during the six months ended June 30, 2021. No payments were received from from Middlemount during the six months ended June 30, 2020.
One of the Company’s Australian subsidiaries and the other shareholder of Middlemount are parties to an agreement, as amended from time to time, to provide a revolving loan (Revolving Loans) to Middlemount. The Company’s participation in the Revolving Loans will not, at any time, exceed its 50% equity interest of the revolving loan limit. At June 30, 2021, the revolving loan limit was $160 million Australian dolla rs and the Revolving Loans were not fully drawn upon by Middlemount. The Revolving Loans bear interest at 10% per annum and expire on December 31, 2021. T he value of the portion of the Revolving Loans due to the Company’s Australian subsidiary was $42.9 million and $46.2 million as of June 30, 2021 and December 31, 2020, respectively, with the decreas e during the six months ended June 30, 2021 primarily attributable to payments made by Middlemount.
As of both June 30, 2021 and December 31, 2020, the financing receivables and Revolving Loans are accounted for as in-substance common stock due to the limited fair value attributed to Middlemount’s equi ty.
(7) Derivatives and Fair Value Measurements
Derivatives
Corporate Risk Management Activities
From time to time, the Company may utilize various types of derivative instruments to manage its exposure to risks in the normal course of business, including (1) foreign currency exchange rate risk and the variability of cash flows associated with forecasted Australian dollar expenditures made in its Australian mining platform, (2) price risk of fluctuating coal prices related to forecasted sales or purchases of coal, or changes in the fair value of a fixed price physical sales contract, (3) price risk and the variability of cash flows related to forecasted diesel fuel purchased for use in its operations and (4) interest rate risk on long-term debt. These risk management activities are actively monitored for compliance with the Company’s risk management policies.
As of June 30, 2021, the Company had currency options outstanding with an aggregate notional amount of $580.0 million Australian dollars to hedge currency risk associated with anticipated Australian dollar expenditures over the nine-month period ending March 31, 2022. The instruments are quarterly average rate options which entitle the Company to receive payment on the notional amount should the quarterly average Australian dollar-to-U.S. dollar exchange rate exceed amounts ranging from $0.80 to $0.81 over the nine-month period ending March 31, 2022.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)
As of June 30, 2021, the Company held coal-related financial contracts related to a portion of its forecasted sales for an aggregate notional volume of 2.8 million tonnes. Such financial contracts may include include futures, forwards and options. Of the aggregate notional volume, 0.4 million tonnes will settle during the second half of 2021, 2.0 million tonnes will settle in 2022, and the remainder will settle in 2023.
The Company had no diesel fuel or interest rate derivatives in place as of June 30, 2021.
Coal Trading Activities
On a limited basis, the Company engages in the direct and brokered trading of coal and freight-related contracts (coal trading). Except those contracts for which the Company has elected to apply a normal purchases and normal sales exception, all derivative coal trading contracts are accounted for at fair value.
Tabular Derivatives Disclosures
The Company has master netting agreements with certain of its counterparties which allow for the settlement of contracts in an asset position with contracts in a liability position in the event of default or termination. Such netting arrangements reduce the Company’s credit exposure related to these counterparties. For classification purposes, the Company records the net fair value of all the positions with a given counterparty as a net asset or liability in the condensed consolidated balance sheets. The fair value of derivatives reflected in the accompanying condensed consolidated balance sheets are set forth in the table below.

The net amount of asset derivatives, net of margin, are included in “Other current assets” and the net amount of liability derivatives, net of margin, are included in “Accounts payable and accrued expenses” in the accompanying condensed consolidated balance sheets.
The Company had a current asset representing cash collateral held as initial margin for derivative positions primarily related to coal derivatives of $14.4 million and $3.0 million at June 30, 2021 and December 31, 2020, respectively. These amounts are not included with the derivatives presented in the table above and are included in “Other current assets” in the accompanying condensed consolidated balance sheets.
Currently, the Company does not seek cash flow hedge accounting treatment for its derivative financial instruments and thus changes in fair value are reflected in current earnings.

Fair Value Measurements
The Company uses a three-level fair value hierarchy that categorizes assets and liabilities measured at fair value based on the observability of the inputs utilized in the valuation. These levels include: Level 1 - inputs are quoted prices in active markets for the identical assets or liabilities; Level 2 - inputs are other than quoted prices included in Level 1 that are directly or indirectly observable through market-corroborated inputs; and Level 3 - inputs are unobservable, or observable but cannot be market-corroborated, requiring the Company to make assumptions about pricing by market participants.
The following tables set forth the hierarchy of the Company’s net financial asset positions for which fair value is measured on a recurring basis:

| June 30, 2021
| Level 1 |  | Level 2 |  | Level 3 |  | Total

Total net financial assets | $ | — |  |  | $ | 9.2 |  |  | $ | 4.0 |  |  | $ | 13.2 |

For Level 1 and 2 financial assets and liabilities, the Company utilizes both direct and indirect observable price quotes, including interest rate yield curves, exchange indices, broker/dealer quotes, published indices, issuer spreads, benchmark securities and other market quotes. In the case of certain debt securities, fair value is provided by a third-party pricing service. Below is a summary of the Company’s valuation techniques for Level 1 and 2 financial assets and liabilities:
•Foreign currency option contracts are valued utilizing inputs obtained in quoted public markets (Level 2) except when credit and non-performance risk is considered to be a significant input, then the Company classifies such contracts as Level 3.
•Coal contracts related to forecasted sales and coal trading contracts are generally valued based on unadjusted quoted prices in active markets (Level 1) or a valuation that is corroborated by the use of market-based pricing (Level 2) except when credit and non-performance risk is considered to be a significant input (greater than 10% of fair value), then the Company classifies as Level 3.
•Investments in equity securities are based on observed prices in an inactive market (Level 3).
Other Financial Instruments. The following methods and assumptions were used by the Company in estimating fair values for other financial instruments as of June 30, 2021 and December 31, 2020:
•Cash and cash equivalents, restricted cash, accounts receivable, including those within the Company’s accounts receivable securitization program, notes receivable and accounts payable have carrying values which approximate fair value due to the short maturity or the liquid nature of these instruments.
•Long-term debt fair value estimates are based on observed prices for securities when available (Level 2), and otherwise on estimated borrowing rates to discount the cash flows to their present value (Level 3).

Market risk associated with the Company’s fixed- and variable-rate long-term debt relates to the potential reduction in the fair value and negative impact to future earnings, respectively, from an increase in interest rates. The fair value of debt, shown below, is principally based on reported market values and estimates based on interest rates, maturities, credit risk, underlying collateral and completed market transactions, which have been limited in recent history.

| June 30, 2021 |  | December 31, 2020

Net carrying amount | $ | 1,418.1 |  |  | $ | 1,547.8 |
Estimated fair value | $ | 1,179.4 |  |  | $ | 987.6 |

The Company’s risk management function, which is independent of the Company’s coal trading function, is responsible for valuation policies and procedures, with oversight from executive management. The fair value of the Company’s coal derivative assets and liabilities reflects adjustments for credit risk. The Company’s exposure is substantially with electric utilities, energy marketers, steel producers and nonfinancial trading houses.
The Company had no transfers between Levels 1, 2 and 3 during the three and six months ended June 30, 2021 and 2020. The Company’s policy is to value all transfers between levels using the beginning of period valuation.

Asset Impairment and Other At-Risk Assets
During the three and six months ended June 30, 2020, the Company recognized an asset impairment charge of $1,418.1 million related to its North Antelope Rochelle Mine of the Powder River Basin Mining segment. Of this amount, $1,393.7 million related to the property, plant, equipment and mine development assets; $19.9 million related to operating lease right-of-use assets; and $4.5 million related to contract-based intangible assets. The outlook for the mine was negatively impacted by the accelerated decline of coal-fired electricity generation in the U.S., driven by the reduced utilization of plants and plant retirements, sustained low natural gas pricing and the increased use of renewable energy sources. These factors led to the expectation of reduced future sales volumes. The impairment charge was based upon the remaining estimated discounted cash flows of the mine. Such cash flows were based upon estimates which generally constitute unobservable Level 3 inputs under the fair value hierarchy, including, but not limited to, future tons sold, coal prices for unpriced coal, production costs (including costs for labor, commodity supplies and contractors), transportation costs and a risk-adjusted, cost of capital.
No asset impairment charges were recorded during the three and six months ended June 30, 2021.
The Company has identified certain assets with an aggregate carrying value of approximately $1.2 billion at June 30, 2021 in its Seaborne Metallurgical Mining, Powder River Basin Mining, Other U.S. Thermal Mining and Corporate and Other segments whose recoverability is most sensitive to coal pricing, cost pressures, customer demand, customer concentration risk and future economic viability. The Company conducted a review of those assets for recoverability as of June 30, 2021 and determined that no impairment charges were necessary as of that date.

(9) Leases
The Company has operating and finance leases for mining and non-mining equipment, office space and certain other facilities under various non-cancellable agreements. Historically, the majority of the Company’s leases have been accounted for as operating leases. Refer to Note 1. “Summary of Significant Accounting Policies” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020, for the Company’s policies regarding “Leases.”
The Company and certain of its subsidiaries have guaranteed other subsidiaries’ performance under various lease obligations. Certain lease agreements are subject to the restrictive covenants of the Company’s credit facilities and include cross-acceleration provisions, under which the lessor could require remedies including, but not limited to, immediate recovery of the present value of any remaining lease payments. The Company typically agrees to indemnify lessors for the value of the property or equipment leased, should the property be damaged or lost during the course of the Company’s operations. The Company expects that losses with respect to leased property, if any, may be covered by insurance (subject to deductibles). Aside from indemnification of the lessor for the value of the property leased, the Company’s maximum potential obligations under its leases are equal to the respective future minimum lease payments, and the Company assumes that no amounts could be recovered from third parties.
The components of lease expense during the three and six months ended June 30, 2021 and 2020 were as follows:

Refinancing Transactions
On January 29, 2021 (the Settlement Date), the Company completed a series of transactions (collectively, the Refinancing Transactions) to, among other things, provide the Company with maturity extensions and covenant relief, while allowing it to maintain near-term operating liquidity and financial flexibility. The Refinancing Transactions included a senior notes exchange and related consent solicitation, a revolving credit facility exchange and various amendments to the Company’s existing debt agreements, as summarized below. As further discussed in Note 16. “Financial Instruments and Other Guarantees,” upon completion of the Refinancing Transactions, the surety transaction support agreement (Surety Agreement) entered into with the Company’s surety bond providers in November 2020 became effective.
On the Settlement Date, the Company settled an exchange offer (Exchange Offer) pursuant to which $398.7 million aggregate principal amount of the Company’s 6.000% Senior Secured Notes due March 2022 (the 2022 Notes) were validly tendered, accepted by the Company and exchanged for aggregate consideration consisting of (a) $193.9 million aggregate principal amount of new 10.000% Senior Secured Notes due December 2024 (Co-Issuer Notes) issued by certain wholly-owned subsidiaries of the Company (the Co-Issuers), (b) $195.1 million aggregate principal amount of new 8.500% Senior Secured Notes due December 2024 issued by the Company (Peabody Notes) and (c) a cash payment of approximately $9.4 million. In connection with the settlement of the Exchange Offer, the Company also paid early tender premiums totaling $4.0 million in cash. The Company’s Wilpinjong Mine in Australia is owned and operated by a subsidiary of the Co-Issuers.
The Exchange Offer was accounted for as a debt modification based upon the relative similarity of the present value of the future cash flows of the instruments. As such, no gain or loss was recorded in connection with the Exchange Offer. Fees paid to third parties of $10.6 million were included in “Interest expense” in the accompanying unaudited condensed consolidated statements of operations during the six months ended June 30, 2021.
Concurrently with the Exchange Offer, the Company solicited consents from holders of the 2022 Notes to certain proposed amendments to its existing senior notes’ indenture (the Existing Indenture) to (i) eliminate substantially all of the restrictive covenants, certain events of default applicable to the 2022 Notes and certain other provisions contained in the Existing Indenture and (ii) release the collateral securing the 2022 Notes and eliminate certain other related provisions contained in the Existing Indenture. The Company received the requisite consents from holders of the 2022 Notes and entered into a supplemental indenture to the Existing Indenture, which became operative on January 29, 2021.
In connection with the Refinancing Transactions, the Company restructured the revolving loans under its existing credit agreement (the Credit Agreement) by (i) making a pay down of revolving loans thereunder in the aggregate amount of $10.0 million, (ii) the Co-Issuers incurring $206.0 million of term loans under a credit agreement, dated as of the Settlement Date (Co-Issuer Term Loans, Co-Issuer Term Loan Agreement), (iii) the Company entering into a letter of credit facility (the Company LC Agreement) and (iv) amending the Credit Agreement (collectively, the Revolver Transactions).
Co-Issuer Notes
The terms of the Co-Issuer Notes are governed by an indenture, as amended and restated as of February 3, 2021, by and among the Co-Issuers, Wilmington Trust, National Association, as trustee, and, on a limited basis, the Company (Co-Issuer Notes Indenture).
The Co-Issuer Notes mature on December 31, 2024 and bear interest at an annual rate of 10.000%. The Company paid aggregate debt issuance costs of $5.6 million, which are being amortized over the terms of the notes. Beginning March 31, 2021, interest is payable on March 31, June 30, September 30 and December 31 of each year. During the three and six months ended June 30, 2021, the Company recorded interest expense of $5.3 million and $8.9 million, respectively, related to the Co-Issuer Notes.
The Co-Issuer Notes are subject to amortization at the end of each six-month period, beginning with June 30, 2021, whereby the Excess Cash Flow (as defined in the Co-Issuer Notes Indenture) generated by the Wilpinjong Mine during each such period will be applied to the principal of the Co-Issuer Notes and the Co-Issuer Term Loans on a pro rata basis, provided that the liquidity attributable to the Co-Issuers would not fall below $60.0 million.
The Co-Issuer Notes Indenture contains customary covenants that, among other things, limit the Co-Issuers’ and their subsidiaries’ ability to incur additional Indebtedness, pay dividends on or make distributions in respect of capital stock or make certain other restricted payments or investments, enter into agreements that restrict distributions from subsidiaries, sell or otherwise dispose of assets, enter into transactions with affiliates, create or incur liens, and merge, consolidate or sell all or substantially all of their assets, and place restrictions on the ability of subsidiaries to pay dividends or make other payments to the Co-Issuers.

The Co-Issuer Notes are not guaranteed by any of the Co-Issuers’ subsidiaries and thus are structurally subordinated to any existing or future Indebtedness or other liabilities, including trade payables, of any such subsidiaries. The Co-Issuer Notes initially are secured by liens on substantially all of the assets of the Co-Issuers, including by (i) 100% of the capital stock of PIC Acquisition Corp. owned by PIC AU Holdings LLC and (ii) all other property subject or purported to be subject, from time to time, to a lien under the Co-Issuers’ collateral trust agreement (collectively, the Wilpinjong Collateral).
The Co-Issuers may redeem some or all of the Co-Issuer Notes at the redemption prices and on the terms specified in the Co-Issuer Notes Indenture.
The Co-Issuer Notes Indenture contains certain events of default, including, in certain circumstances, (i) specified events occurring at the Wilpinjong Mine, (ii) the termination or modification of the Surety Agreement, (iii) the Company’s failure to comply with any obligation under the transaction support agreement entered into prior to, and in contemplation of, the Refinancing Transactions and (iv) the termination of the management services agreements between the Company and the Co-Issuers. If the Co-Issuer Notes are accelerated or otherwise become due and payable as a result of an event of default, certain additional premium amounts may become due and payable in addition to unpaid principal and interest at the time of acceleration. In addition, the holders of the Co-Issuer Notes have the right, under certain circumstances specified in the Co-Issuer Notes Indenture, to exchange their Co-Issuer Notes for Peabody Notes.

During the three and six months ended June 30, 2021, the Company recorded interest expense of $3.9 million and $7.0 million, respectively, related to the Peabody Notes, which included in-kind interest of approximately $0.8 million and $1.6 million, respectively.
As a requirement of the Exchange Offer, during the three months ended March 31, 2021, the Company purchased $22.4 million of the Peabody Notes at 80% of their accreted value, plus accrued and unpaid interest. In connection with the purchases, the Company recognized a net gain of $3.5 million to “Net gain on early debt extinguishment” during the six months ended June 30, 2021. The notes were subsequently canceled.

The Peabody Notes are unconditionally guaranteed, jointly and severally, on a senior secured basis by the Peabody Guarantors (as defined below) on the Peabody Collateral (as defined below). The obligations are secured on a pari passu basis by the same collateral that secures the 6.375% Senior Secured Notes due March 2025 (the 2025 Notes), the Credit Agreement and the Company LC Agreement described below.
Co-Issuer Term Loans

From time to time, the Company initiates restructuring activities in connection with its repositioning efforts to appropriately align its cost structure or optimize its coal production relative to prevailing market conditions. Costs associated with restructuring actions can include the impact of early mine closures, voluntary and involuntary workforce reductions, office closures and other related activities. Costs associated with restructuring activities are recognized in the period incurred. Such charges included as “Restructuring charges” in the Company's unaudited condensed consolidated statements of operations amounted to $2.1 million and $4.2 million for the three and six months ended June 30, 2021, respectively, and $16.5 million and $23.0 million for the three and six months ended June 30, 2020, respectively, were associated with both involuntary and voluntary workforce reductions.
The Shoal Creek Mine remains idled as the Company continues activities to increase productivity, lower costs and improve yields from the operation in the future. The preparation plant upgrade project remains on schedule with completion expected in the middle of the third quarter of 2021. The Shoal Creek labor contract expired in April 2021, and negotiations with the workforce are ongoing.
The Metropolitan Mine full workforce returned to the mine in early May. Development work at the mine has been ongoing and longwall production restarted late in the second quarter of 2021, with a ramp up to planned production levels in the third quarter of 2021. The underground workforce enterprise agreement expired in January 2021 and after a period of ongoing negotiation, an application was made to terminate the underground labor agreement. That application is pending.
Subsequent to June 30, 2021, the Company executed transactions to sell its closed Millennium and Wilkie Creek Mines to reduce its closed mine reclamation liabilities and associated costs. The Company is in process of assessing the financial impacts of the sales, but anticipates recording cumulative gains of $40 million to $50 million in the third quarter of 2021, with minimal cash consideration received.
(15) Earnings per Share (EPS)
Basic EPS is computed based on the weighted average number of shares of common stock outstanding during the period. Diluted EPS is computed based on the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding. As such, the Company includes the share-based compensation awards in its potentially dilutive securities. Dilutive securities are not included in the computation of loss per share when a company reports a net loss from continuing operations as the impact would be anti-dilutive.
For all but performance units, the potentially dilutive impact of the Company’s share-based compensation awards is determined using the treasury stock method. Under the treasury stock method, awards are treated as if they had been exercised with any proceeds used to repurchase common stock at the average market price during the period. Any incremental difference between the assumed number of shares issued and purchased is included in the diluted share computation. For performance units, their contingent features result in an assessment for any potentially dilutive common stock by using the end of the reporting period as if it were the end of the contingency period for all units granted.
The computation of diluted EPS excluded aggregate share-based compensation awards of approximately 1.2 million and 2.2 million for the three months ended June 30, 2021 and 2020, respectively, and 1.2 million and 2.5 million for the six months ended June 30, 2021 and 2020, respectively, because to do so would have been anti-dilutive for those periods. Because the potential dilutive impact of such share-based compensation awards is calculated under the treasury stock method, anti-dilution generally occurs when the exercise prices or unrecognized compensation cost per share of such awards are higher than the Company’s average stock price during the applicable period. Anti-dilution also occurs when a company reports a net loss from continuing operations, and the dilutive impact of all share-based compensation awards are excluded accordingly.

(16) Financial Instruments and Other Guarantees
The Company is a party to various guarantees and financial instruments that carry off-balance-she et risk and are not reflected in the accompanying condensed consolidated balance sheets. At June 30, 2021, such instruments included $1,555.0 million of surety bonds and $435.4 million of letters of credit. Such financial instruments provide support for the Company’s reclamation bonding requirements, lease obligations, insurance policies and various other performance guarantees. Reclamation bonding requirements are typically established by statute or under mining permits. At June 30, 2021, the Company’s asset retirement obligations of $741.8 million were supported by surety bonds of $1,379.0 million, as well as letters of credit issued under the Company’s receivables securitization program and the Company LC Agreement. Letters of credit issued at June 30, 2021 which served as collateral for surety bonds in support of asset retirement obligations amounted to $310.5 million.
In November 2020, the Company entered into a Surety Agreement with the providers of 99% of its surety bond portfolio (Participating Sureties) to resolve previous collateral demands made by the Participating Sureties. In accordance with the Surety Agreement, the Company initially provided $75.0 million of collateral, in the form of letters of credit.
Upon completion of the Refinancing Transactions described in Note 11. “Long-term Debt,” other provisions of the Surety Agreement became effective. In particular, the Company granted second liens on $200.0 million of certain mining equipment and will post an additional $25.0 million of collateral per year from 2021 through 2024 for the benefit of the Participating Sureties. The collateral postings may also further increase to the extent the Company generates more than $100.0 million of free cash flow (as defined in the Surety Agreement) in any twelve-month period or has cumulative asset sales in excess of $10.0 million, as of the last quarter end during the term of the agreement. Further, the Participating Sureties have agreed to a standstill through the earlier of December 31, 2025, or the maturity of the Credit Agreement (currently March 31, 2025), during which time, the Participating Sureties will not demand any additional collateral, draw on letters of credit posted for the benefit of themselves or cancel any existing surety bond. The Company will not pay dividends or make share repurchases during the standstill period, unless otherwise agreed between parties. In connection withe Refinancing Transactions, at the Settlement Date, all letters of credit issued under the Company’s former revolving credit facility were deemed issued under the Company LC Agreement in support of the same obligations.
The Company periodically evaluates the instruments for on-balance sheet treatment based on the amount of exposure under the instrument and the likelihood of required performance. The Company does not expect any material losses to result from these guarantees or off-balance-sheet instruments in excess of liabilities provided for in the accompanying condensed consolidated balance sheets.

Accounts Receivable Securitization
The Company is party to an accounts receivable securitization agreement (Securitization Program) which expires in April 2022 and provides up to $250.0 million in funding, limited to the availability of eligible receivables, and may be secured by a combination of collateral and the trade receivables underlying the program, from time to time. Funding capacity under the Securitization Program may also be utilized for letters of credit in support of other obligations. The borrowings under the Securitization Program bear interest at LIBOR plus 1.5% per annum and remain outstanding throughout the term of the agreement, subject to the Company maintaining sufficient eligible receivables, by continuing to contribute trade receivables, unless an event of default occurs. The Securitization Program is subject to customary events of default.
Under the terms of the Securitization Program, the Company contributes the trade receivables of its participating subsidiaries on a revolving basis to a wholly-owned, bankruptcy-remote subsidiary, which then sells the receivables to unaffiliated banks. The Securitization Program does not receive off-balance sheet accounting treatment due to the Company’s ability to repurchase the receivables in certain circumstances.
At June 30, 2021, the Com pany had no outstanding borrowings and $125.5 million o f letters of credit issued under the Securitization Program. The letters of credit were primarily in support of reclamation obligations. Availability under the Securitizatio n Program, which is adjusted for certain ineligible receivables, was $0.3 million at June 30, 2021. The Company had $13.6 million of cash collateral posted under the Securitization Program at June 30, 2021 due to outstanding letters of credit temporarily exceeding the balance of eligible receivables at quarter-end and none at December 31, 2020. This cash collateral is recorded as “Restricted cash” in the accompanying condensed consolidated balance sheets.
The Company incurred interest and fees associated with the Securitization Program of $0.7 million and $0.8 million during the three months ended June 30, 2021 and 2020, respectively, and $1.4 million and $1.5 million during the six months ended June 30, 2021 and 2020, respectively, which have been recorded as “Interest expense” in the accompanying unaudited condensed consolidated statements of operations.
Other
Substantially all of the Company’s U.S. subsidiaries provide financial guarantees under long-term debt agreements entered into by the Company. The maximum amounts payable under the Company’s debt agreements are equal to the respective principal and interest payments.
(17) Commitments and Contingencies
Commitments
Unconditional Purchase Obligations
As of June 30, 2021, purchase commitments for capital expenditures were $28.1 million, all of which is obligated within the next four years, with $20.6 million obligated within the next 12 months.
There were no other material changes to the Company’s commitments from the information provided in Note 24. “Commitments and Contingencies” to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.

Litigation Relating to Continuing Operations
Securities Class Action. On September 28, 2020, the Oklahoma Firefighters Pension and Retirement System brought a lawsuit, styled In Re Peabody Energy Corporation Securities Litigation No. 1:20-cv-08024 (PKC), against the Company and certain of its officers in the U.S. District Court for the Southern District of New York (the Court) on behalf of a putative class of shareholders (Plaintiffs) who held Company stock between April 3, 2017 and October 28, 2019, for alleged violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder (Securities Class Action). Plaintiffs allege that the defendants made false or misleading statements and/or failed to disclose certain adverse facts pertaining to safety practices at the Company’s North Goonyella Mine and the events leading up to a fire at the mine, and that, after a September 28, 2018 fire at the mine, made false or misleading statements and/or failed to disclose certain adverse facts pertaining to the feasibility of the Company’s plan to restart the mine after the fire. The Company believes the lawsuit lacks merit and intends to vigorously defend against the allegations. On January 12, 2021, the Court appointed the Oregon Public Employees Retirement Fund as lead plaintiff. On January 25, 2021, the Court entered a scheduling order for this matter. Plaintiffs filed their amended complaint on March 19, 2021. The defendants filed a pre-motion letter on April 30, 2021 while the Plaintiffs’ response letter was filed on May 6, 2021. The defendants filed their motion to dismiss on June 7, 2021. The Plaintiffs’ opposition brief to the motion to dismiss was filed on July 22, 2021. Additional briefings at this phase of litigation are anticipated to be completed by the conclusion of August 2021.
Derivative Actions. On December 22, 2020, a plaintiff (Phelps), putatively on behalf of the Company, brought a shareholder derivative lawsuit, styled Phelps v. Samantha Algaze, et al., Case No. 1:20-cv-01747-UNA (D. Del. filed Dec. 22, 2020), in the U.S. District Court for the District of Delaware against certain directors and former officers of the Company, as defendants. The Company was also named as a nominal defendant. The plaintiff did not make a demand on the Company’s board before instituting the lawsuit and alleges such demand would have been futile. In the complaint, the plaintiff alleges that the defendants failed to disclose adverse facts relating to the safety practices at the Company’s North Goonyella Mine, thereby leading to a September 28, 2018 fire, and allegedly failed to disclose adverse facts pertaining to the feasibility of reopening the mine. The derivative complaint alleges (i) contribution against certain current and former officers for securities fraud based on the Securities Class Action, and against all defendants, (ii) breach of fiduciary duties, (iii) waste of corporate assets for causing the Company to incur legal liability and (iv) unjust enrichment.
On February 10, 2021, a second plaintiff (Di Fusco), putatively on behalf of the Company, filed a similar shareholder derivative lawsuit, styled Di Fusco v. Glenn Kellow, et al., Case No. 1:21-cv-00183-UNA (D. Del. filed Feb. 10, 2021), in the U.S. District Court for the District of Delaware against the directors and current and former officers of the Company, as defendants. The Company was named as a nominal defendant. This suit makes claims similar to those made in the Phelps matter, but asserts a claim for alleged misstatements in a proxy statement under Section 14(a) of the Securities and Exchange Act of 1934. In late March 2021, the parties filed a stipulation agreeing to consolidate and stay both derivative actions for judicial efficiency and cost until the Court ruled on the motion to dismiss in the Securities Class Action. The Company also believes that the derivative actions lack merit and intended to vigorously defend against the allegations.
Other
At times, the Company becomes a party to other disputes, including those related to contract miner performance, claims, lawsuits, arbitration proceedings, regulatory investigations and administrative procedures in the ordinary course of business in the U.S., Australia and other countries where the Company does business. Based on current information, the Company believes that such other pending or threatened proceedings are likely to be resolved without a material adverse effect on its financial condition, results of operations or cash flows. The Company reassesses the probability and estimability of contingent losses as new information becomes available.
(18) Segment Information
The Company reports its results of operations primarily through the following reportable segments: Seaborne Thermal Mining, Seaborne Metallurgical Mining, Powder River Basin Mining, Other U.S. Thermal Mining and Corporate and Other. The Company’s chief operating decision maker uses Adjusted EBITDA as the primary metric to measure the segments’ operating performance.

Adjusted EBITDA is a non-GAAP financial measure defined as loss from continuing operations before deducting net interest expense, income taxes, asset retirement obligation expenses and depreciation, depletion and amortization. Adjusted EBITDA is also adjusted for the discrete items that management excluded in analyzing the segments’ operating performance, as displayed in the reconciliation below. Management believes non-GAAP performance measures are used by investors to measure the Company’s operating performance and lenders to measure the Company’s ability to incur and service debt. Adjusted EBITDA is not intended to serve as an alternative to U.S. GAAP measures of performance and may not be comparable to similarly-titled measures presented by other companies.

Cautionary Notice Regarding Forward-Looking Statements
This report includes statements of Peabody’s expectations, intentions, plans and beliefs that constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the Securities Act) and Section 21E of the Securities Exchange Act of 1934, as amended (the Exchange Act), and are intended to come within the safe harbor protection provided by those sections. These statements relate to future events or Peabody’s future financial performance. The Company uses words such as “anticipate,” “believe,” “expect,” “may,” “forecast,” “project,” “should,” “estimate,” “plan,” “outlook,” “target,” “likely,” “will,” “to be” or other similar words to identify forward-looking statements.
Without limiting the foregoing, all statements relating to Peabody’s future operating results, anticipated capital expenditures, future cash flows and borrowings, and sources of funding are forward-looking statements and speak only as of the date of this report. These forward-looking statements are based on numerous assumptions that Peabody believes are reasonable, but are subject to a wide range of uncertainties and business risks, and actual results may differ materially from those discussed in these statements. These factors are difficult to accurately predict and may be beyond the Company’s control. Factors that could affect its results or an investment in its securities include, but are not limited to:
•the Company’s profitability depends upon the prices it receives for its coal;
•if a substantial number of the Company’s long-term coal supply agreements, including those with its largest customers, terminate, or if the pricing, volumes or other elements of those agreements materially adjust, its revenues and operating profits could suffer if the Company is unable to find alternate buyers willing to purchase its coal on comparable terms to those in its contracts;
•risks inherent to mining could increase the cost of operating the Company’s business, and events and conditions that could occur during the course of its mining operations could have a material adverse impact on the Company;
•the Company’s take-or-pay arrangements could unfavorably affect its profitability;
•the Company may not recover its investments in its mining, exploration and other assets, which may require the Company to recognize impairment charges related to those assets;
•the Company could be negatively affected if it fails to maintain satisfactory labor relations;
•the Company could be adversely affected if it fails to appropriately provide financial assurances for its obligations;
•the Company’s mining operations are extensively regulated, which imposes significant costs on it, and future regulations and developments could increase those costs or limit its ability to produce coal;
•the Company’s operations may impact the environment or cause exposure to hazardous substances, and its properties may have environmental contamination, which could result in material liabilities to the Company;
•the Company may be unable to obtain, renew or maintain permits necessary for its operations, or the Company may be unable to obtain, renew or maintain such permits without conditions on the manner in which it runs its operations, which would reduce its production, cash flows and profitability;
•concerns about the impacts of coal combustion on global climate are increasingly leading to consequences that have affected and could continue to affect demand for the Company’s products or its securities and its ability to produce, including increased governmental regulation of coal combustion and unfavorable investment decisions by electricity generators;
•numerous activist groups are devoting substantial resources to anti-coal activities to minimize or eliminate the use of coal as a source of electricity generation, domestically and internationally, thereby further reducing the demand and pricing for coal, and potentially materially and adversely impacting the Company’s future financial results, liquidity and growth prospects;
•the Company’s trading and hedging activities do not cover certain risks and may expose it to earnings volatility and other risks;
•if the assumptions underlying the Company’s asset retirement obligations for reclamation and mine closures are materially inaccurate, its costs could be significantly greater than anticipated;
30

•the Company’s future success depends upon its ability to continue acquiring and developing coal reserves that are economically recoverable;
•the Company faces numerous uncertainties in estimating its economically recoverable coal reserves and inaccuracies in its estimates could result in lower than expected revenues, higher than expected costs and decreased profitability;
•joint ventures, partnerships or non-managed operations may not be successful and may not comply with the Company’s operating standards;
•the Company may undertake further repositioning plans that would require additional charges;
•the Company’s business, results of operations, financial condition and prospects could be materially and adversely affected by the coronavirus (COVID-19) pandemic and the related effects on public health;
•the Company’s expenditures for postretirement benefit obligations could be materially higher than it has predicted if its underlying assumptions prove to be incorrect;
•the Company is subject to various general operating risks which may be fully or partially outside of its control;
•the Company’s financial performance could be adversely affected by its funded indebtedness (Indebtedness);
•despite the Company’s Indebtedness, it may still be able to incur more debt, which could further increase the risks associated with its Indebtedness;
•the terms of the indentures governing the Company’s senior secured notes and the agreements and instruments governing its other Indebtedness and surety bonding obligations impose restrictions that may limit its operating and financial flexibility;
•the number and quantity of viable financing and insurance alternatives available to the Company may be significantly impacted by unfavorable lending and investment policies by financial institutions and insurance companies associated with concerns about environmental impacts of coal combustion, and negative views around its efforts with respect to environmental and social matters and related governance considerations could harm the perception of the Company by a significant number of investors or result in the exclusion of its securities from consideration by those investors;
•the price of Peabody’s securities may be volatile and could fall below the minimum allowed by New York Stock Exchange listing requirements;
•Peabody’s common stock is subject to dilution and may be subject to further dilution in the future;
•there may be circumstances in which the interests of a significant stockholder could be in conflict with other stakeholders’ interests;
•the payment of dividends on Peabody’s stock or repurchase of its stock is dependent on a number of factors, and future payments and repurchases cannot be assured;
•the Company may not be able to fully utilize its deferred tax assets;
•acquisitions and divestitures are a potentially important part of the Company’s long-term strategy, subject to its investment criteria, and involve a number of risks, any of which could cause the Company not to realize the anticipated benefits;
•Peabody’s certificate of incorporation and by-laws include provisions that may discourage a takeover attempt;
•diversity in interpretation and application of accounting literature in the mining industry may impact the Company’s reported financial results; and
•other risks and factors detailed in this report, including, but not limited to, those discussed in “Legal Proceedings,” set forth in Part II, Item 1 and in “Risk Factors,” set forth in Part II, Item 1A of this Quarterly Report on Form 10-Q.
When considering these forward-looking statements, you should keep in mind the cautionary statements in this document and in the Company’s other Securities and Exchange Commission (SEC) filings, including, but not limited to, the more detailed discussion of these factors and other factors that could affect its results contained in Item 1A. “Risk Factors” and Item 3. “Legal Proceedings” of its Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC on February 23, 2021. These forward-looking statements speak only as of the date on which such statements were made, and the Company undertakes no obligation to update these statements except as required by federal securities laws.

During the fourth quarter of 2020 and the first quarter of 2021, the Company entered into a series of interrelated agreements with its surety bond providers, the revolving lenders under its credit agreement and certain holders of its senior secured notes to extend a significant portion of its near-term debt maturities to December 2024 and to stabilize collateral requirements for its existing surety bond portfolio.
During the second quarter of 2021, and continuing into the third quarter of 2021, the Company completed a series of additional financing transactions intended to improve its capital structure. These transactions included at-the-market common stock issuances for cash proceeds, common stock issuances for the retirement of long-term debt and the retirement of long-term debt primarily through open market purchases.
Refer to the “Liquidity and Capital Resources” section contained within this Item 2 for a further discussion of these financing and surety transactions.
Other
From time to time, the Company initiates restructuring activities in connection with its repositioning efforts to appropriately align its cost structure or optimize its coal production relative to prevailing market conditions. As further described in the “Results of Operations” section contained within this Item 2, the Company incurred restructuring charges of $2.1 million and $16.5 million during the three months ended June 30, 2021 and 2020, respectively, and $4.2 million and $23.0 million during the six months ended June 30, 2021 and 2020, respectively, related to workforce reductions made across the organization through both involuntary and voluntary reductions.
The Shoal Creek Mine remains idled as the Company continues activities to increase productivity, lower costs and improve yields from the operation in the future. The preparation plant upgrade project remains on schedule with completion expected in the middle of the third quarter of 2021. The Shoal Creek labor contract expired in April 2021, and negotiations with the workforce are ongoing.
The Metropolitan Mine full workforce returned to the mine in early May. Development work at the mine has been ongoing and longwall production restarted late in the second quarter of 2021, with a ramp up to planned production levels in the third quarter of 2021. The underground workforce enterprise agreement expired in January 2021 and after a period of ongoing negotiation, an application was made to terminate the underground labor agreement. That application is pending.
Subsequent to June 30, 2021, the Company executed transactions to sell its closed Millennium and Wilkie Creek Mines to reduce its closed mine reclamation liabilities and associated costs. The Company is in process of assessing the financial impacts of the sales, but anticipates recording cumulative gains of $40 million to $50 million in the third quarter of 2021, with minimal cash consideration received.

Three and Six Months Ended June 30, 2021 Compared to the Three and Six Months Ended June 30, 2020
Summary
Spot pricing for premium low-vol hard coking coal (Premium HCC), premium low-vol pulverized coal injection (Premium PCI) coal, Newcastle index thermal coal and API 5 thermal coal, and prompt month pricing for PRB 8,880 Btu/Lb coal and Illinois Basin 11,500 Btu/Lb coal during the three months ended June 30, 2021 is set forth in the table below.
The seaborne pricing included in the table below is not necessarily indicative of the pricing the Company realized during the three months ended June 30, 2021 due to quality differentials and the majority of its seaborne sales being executed through annual and multi-year international coal supply agreements that contain provisions requiring both parties to renegotiate pricing periodically. The Company’s typical practice is to negotiate pricing for seaborne metallurgical coal contracts on a quarterly, spot or index basis and seaborne thermal coal contracts on an annual, spot or index basis.
In the U.S., the pricing included in the table below is also not necessarily indicative of the pricing the Company realized during the three months ended June 30, 2021 since the Company generally sells coal under long-term contracts where pricing is determined based on various factors. Such long-term contracts in the U.S. may vary significantly in many respects, including price adjustment features, price reopener terms, coal quality requirements, quantity parameters, permitted sources of supply, treatment of environmental constraints, extension options, force majeure and termination and assignment provisions. Competition from alternative fuels such as natural gas and other fuel sources may also impact the Company’s realized pricing.

Within the seaborne metallurgical coal market, record steel production and tight coal availability have driven Australian spot prices to the highest level in two years. China’s unofficial ban on Australian coal remains in place and continues to support delivered China prices above those of all other markets. This is incentivizing producers in Russia, the U.S. and Canada to supply China with additional volumes, providing opportunities for Australia to supply customers typically serviced by these countries. COVID-19 remains an ongoing risk to seaborne metallurgical coal demand and has recently impacted import volumes to India and Japan.
Within the seaborne thermal coal market, tight supplies and elevated demand have driven Newcastle thermal coal pricing to levels not seen in over 10 years. China’s domestic thermal coal supply remains hampered by heightened safety inspections and mine suspensions. The relaxation of China’s import controls combined with tight domestic supply has pushed import demand higher. In addition, India’s thermal coal imports improved ahead of the monsoon season. However, supply response to elevated demand has been muted year-to-date, sending thermal coal prices higher.
In the United States, overall electricity demand increased 4% year-over-year, positively impacted by weather and the prior year economic impacts of COVID. Electricity generation from thermal coal has notably improved year-over-year as a result of higher natural gas prices and stronger overall electricity demand. This has positively impacted coal’s share of electricity generation, with a rise to approximately 22% for the six months ended June 30, 2021, while causing natural gas’s share to decline to approximately 36%. Stronger coal use has contributed to decreasing coal stockpile levels. Since December 2020, coal inventories have fallen by approximately 17 million tons. Through the six months ended June 30, 2021, utility consumption of PRB coal rose approximately 35% compared to the prior year period.
The Company’s revenues for the three months ended June 30, 2021 increased compared to the same period in 2020 ($96.7 million) primarily due to the impact of higher sales volumes and higher seaborne thermal pricing. Revenues for the six months ended June 30, 2021 decreased compared to the same period in 2020 ($98.2 million) primarily due to lower realized prices and lower sales volumes.
Results from continuing operations, net of income taxes for the three months ended June 30, 2021 increased compared to the same period in the prior year ($1,522.3 million) primarily due to the asset impairment charges recorded in the prior year period ($1,418.1 million) and the favorable revenue variance described above.
Results from continuing operations, net of income taxes for the six months ended June 30, 2021 increased compared to the same period in the prior year ($1,573.9 million) primarily due to the asset impairment charges recorded in the prior year period ($1,418.1 million), lower operating costs and expenses driven by the sales volume decline as well as production efficiencies and other cost improvements ($141.8 million) and lower depreciation, depletion and amortization ($48.9 million). These favorable variances were offset by the unfavorable revenue variance described above and increased interest expense ($30.4 million) primarily resulting from fees and higher borrowing rates related to new debt arrangements entered into during the first quarter of 2021.
Adjusted EBITDA for the three and six months ended June 30, 2021 reflected a year-over-year increase of $98.7 million and $123.0 million, respectively.
As of June 30, 2021, the Company’s available liquidity was approximately $564 million. Refer to the “Liquidity and Capital Resources” section contained within this Item 2 for a further discussion of factors affecting the Company’s available liquidity.

(3)Includes trading and brokerage activities, costs associated with post-mining activities, gains (losses) on certain asset disposals, minimum charges on certain transportation-related contracts, costs associated with suspended operations including the North Goonyella Mine and expenses related to the Company’s other commercial activities.
The increase in Corporate and Other Adjusted EBITDA during the three and six months ended June 30, 2021 compared to the same periods in the prior year was driven by lower postretirement healthcare costs (three months, $11.2 million; six months, $22.4 million) primarily due to changes made to one of the Company’s postretirement health care benefit plans announced in 2020; lower containment and holding costs for the Company’s North Goonyella Mine (three months, $8.2 million; six months, $14.4 million); favorable trading results (six months, $11.8 million); a favorable variance in Middlemount’s results due to the combined impact of improved production and cost improvements; and favorable corporate hedging results (six months, $6.2 million).

Additionally, the following table presents a summary of the Company’s weighted-average depletion rate per ton for active mines in each of its mining segments:

| Three Months Ended June 30, |  | Six Months Ended June 30,
| 2021 |  | 2020 |  | 2021 |  | 2020
Seaborne Thermal Mining | $ | 2.47 |  |  | $ | 2.08 |  |  | $ | 2.17 |  |  | $ | 1.99 |
Seaborne Metallurgical Mining | 1.03 |  |  | 1.81 |  |  | 1.02 |  |  | 2.38 |
Powder River Basin Mining | 0.24 |  |  | 0.80 |  |  | 0.24 |  |  | 0.79 |
Other U.S. Thermal Mining | 1.17 |  |  | 0.96 |  |  | 1.15 |  |  | 1.02 |

Depreciation, depletion and amortization expense decreased during the three and six months ended June 30, 2021 compared to the same periods in the prior year primarily due to the impact of the asset impairment recorded at the North Antelope Rochelle Mine during the second quarter of 2020 (three months, $18.8 million; six months, $44.0 million). The decrease in the weighted-average depletion rate per ton for the Seaborne Metallurgical Mining segment during the three and six months ended June 30, 2021 compared to the same periods in the prior year reflects the volume and mix variances which impacted the Company’s revenues as described above. The decrease in the weighted-average depletion rate per ton for the Powder River Basin Mining segment during the three and six months ended June 30, 2021 compared to the same periods in the prior year reflects the asset impairment recorded during the second quarter of 2020.
Restructuring Charges. Restructuring charges decreased during the three and six months ended June 30, 2021 compared to the same periods in the prior year as the result of workforce reductions made across the organization during the prior year.
Transaction Costs Related to Joint Ventures. The charges recorded during the prior year period related to the proposed PRB Colorado joint venture with Arch Resources, Inc. which was terminated during the third quarter of 2020.
Asset Impairment. During the three and six months ended June 30, 2020, the Company recognized $1,418.1 million in aggregate asset impairment charges related to the fair value of its North Antelope Rochelle Mine in its Powder River Basin Mining segment as discussed in Note 8. “Property, Plant, Equipment and Mine Development” to the accompanying unaudited condensed consolidated financial statements.
Interest Expense. Interest expense increased during the three and six months ended June 30, 2021 compared to the same periods in the prior year as the result of a series of refinancing transactions completed by the Company during the first quarter of 2021 as described in Note 11. “Long-term Debt” to the accompanying unaudited condensed consolidated financial statements.
Net Gain on Early Debt Extinguishment. The gain recognized during the three and six months ended June 30, 2021 was primarily related to debt retirements made through various open market purchases during the second quarter of 2021 and the senior notes exchange completed during the first quarter of 2021 as further discussed in Note 11. “Long-term Debt” to the accompanying unaudited condensed consolidated financial statements.
Unrealized (Losses) Gains on Economic Hedges. Unrealized (losses) gains primarily relate to mark-to-market activity from economic hedge activities intended to hedge future coal sales. For additional information, refer to Note 7. “Derivatives and Fair Value Measurements” to the accompanying unaudited condensed consolidated financial statements.
Unrealized (Losses) Gains on Non-Coal Trading Derivative Contracts. Unrealized (losses) gains primarily relate to mark-to-market activity from economic hedge activities intended to hedge foreign currency option contracts. For additional information, refer to Note 7. “Derivatives and Fair Value Measurements” to the accompanying unaudited condensed consolidated financial statements.
Income Tax Benefit (Provision). The increase in the income tax benefit for the three months ended June 30, 2021 compared to the same period in the prior year was primarily due to differences in forecasted taxable income and a decrease in the provision related to the remeasurement of foreign income tax accounts. The increase in the income tax benefit for the six months ended June 30, 2021 compared to the same period in the prior year was primarily due to differences in forecasted taxable income, partially offset by an increase in the provision related to the remeasurement of foreign income tax accounts. Refer to Note 10. “Income Taxes” to the accompanying unaudited condensed consolidated financial statements for additional information.

Regulatory Update
Other than as described in the following section, there were no significant changes to the Company’s regulatory matters subsequent to December 31, 2020. Information regarding the Company’s regulatory matters is outlined in Part I, Item 1. “Business” in its Annual Report on Form 10-K for the year ended December 31, 2020.
Regulatory Matters - U.S.
Clean Air Act (CAA). The CAA, enacted in 1970, and comparable state and tribal laws that regulate air emissions affect the Company’s U.S. coal mining operations both directly and indirectly.
44

Table of Contents
The CAA requires the United States Environmental Protection Agency (EPA) to review national ambient air quality standards (NAAQS) every five years to determine whether revision to current standards are appropriate. As part of this recurring review process, the EPA in 2020 proposed to retain the ozone standards promulgated in 2015, including current secondary standards, and subsequently promulgated final standards to this effect. Fifteen states and other petitioners have filed a petition for review of the rule in the D.C. Circuit. The litigation is currently in abeyance following a motion filed by the EPA to allow for review of the standards.
The EPA also proposed in 2020 to retain the particulate matter (PM) standards last revised in 2012. On December 18, 2020, the EPA issued a final rule to retain both the primary annual and 24-hour PM standards for fine particulate matter (PM 2.5) and the primary 24-hour standard for coarse particulate matter (PM 10) and secondary PM 10 standards. This rule has also been challenged in the D.C. Circuit by several states and environmental organizations. The case is currently in abeyance following a motion filed by the EPA to allow for review of the standards.
More stringent PM or ozone standards would require new state implementation plans to be developed and filed with the EPA and may trigger additional control technology for mining equipment or result in additional challenges to permitting and expansion efforts. This could also be the case with respect to other NAAQS for nitrogen dioxide (NO 2) and sulfur dioxide (SO 2), although there is no significant pending EPA rulemaking with respect to those pollutants.
EPA Regulation of Greenhouse Gas Emissions from Existing Fossil Fuel-Fired EGUs. On October 23, 2015, the EPA published a final rule in the Federal Register regulating greenhouse gas emissions from existing fossil fuel-fired EGUs under Section 111(d) of the CAA (80 Fed. Reg. 64,662 (Oct. 23, 2015)). The rule (known as the Clean Power Plan or CPP) established emission guidelines for states to follow in developing plans to reduce greenhouse gas emissions from existing fossil fuel-fired EGUs. The CPP required that the states individually or collectively create systems that would reduce carbon emissions from any EGU located within their borders by 28% in 2025 and 32% in 2030 (compared with a 2005 baseline).
The EPA subsequently proposed to repeal the CPP and in August 2018 issued a proposed rule to replace the CPP, with the Affordable Clean Energy (ACE) Rule. In June 2019, the EPA issued a combined package that finalized the CPP repeal rule as well as the replacement rule, ACE. The ACE rule sets emissions guidelines for greenhouse gas emissions from existing EGUs based on a determination that efficiency heat rate improvements constitute the Best System of Emission Reduction (BSER). The EPA’s final rule also revises certain regulations to give the states greater flexibility on the content and timing of their state plans.
Based on the EPA’s final rules repealing and replacing the CPP, petitioners in the D.C. Circuit matter seeking review of CPP, including the Company, filed a motion to dismiss, which the court granted in September 2019.
Numerous petitions for review challenging the ACE Rule were filed in the D.C. Circuit and subsequently consolidated. In January 2021, a 3-judge panel of the D.C. Circuit vacated and remanded the ACE Rule to the EPA, including its repeal of the CPP and amendments to the implementing regulations that extended the compliance timeline.
Cross State Air Pollution Rule (CSAPR) and CSAPR Update Rule. In 2011, the EPA finalized the CSAPR, which requires the District of Columbia and 27 states from Texas eastward (not including the New England states or Delaware) to reduce power plant emissions that cross state lines and significantly contribute to ozone and/or fine particle pollution in other states. In 2016, the EPA published the final CSAPR Update Rule which imposed additional reductions in nitrogen oxide emissions beginning in 2017 in 22 states subject to CSAPR.
In October 2020, the EPA proposed a rule to address a previous D.C. Circuit remand of the CSAPR Update Rule. On March 15, 2021, the EPA signed a final rule which imposed further reductions of NOx emmissions in 12 states while determining that 9 states did not significantly contribute to downwind nonattainment and/or maintenance issues and therefore did not require additional emission reductions. In order to implement reductions in the 12 identified states, the EPA issued Federal Implementation Plans to lower state ozone season NOx budgets in 2021 to 2024, although limited emission trading can be used for compliance.
Mercury and Air Toxic Standards (MATS). The EPA published the final MATS rule in the Federal Register in 2012. The MATS rule revised the NSPS for nitrogen oxides, SO 2 and PM for new and modified coal-fueled electricity generating plants, and imposed MACT emission limits on hazardous air pollutants (HAPs) from new and existing coal-fueled and oil-fueled electric generating plants. MACT standards limit emissions of mercury, acid gas HAPs, non-mercury HAP metals and organic HAPs.

Table of Contents
In 2020, the EPA issued a final rule reversing a prior finding and determined that it is not “appropriate and necessary” under the CAA to regulate HAP emissions from coal- and oil-fired power plants. This rule also finalized residual risk and technology review standards for the coal- and oil-fired EGU source category. Both actions have been challenged in the D.C. Circuit and placed in abeyance.
CWA Definition of “Waters of the United States”. In January 2020 the EPA and the Army Corps of Engineers (Corps) finalized the Navigable Waters Protection Rule to revise the definition of “Waters of the United States” and thereby establish the scope of federal regulatory authority under the CWA. The Navigable Waters Protection Rule is currently in effect in all fifty states, but on June 9, 2021, the EPA and the Corps announced their intent to initiate a new rulemaking proceeding to replace the rule with a new definition of “Waters of the United States.” Litigation over the 2020 Navigable Waters Protection Rule remains pending in several federal district courts.
Regulatory Matters - Australia
The Australian mining industry is regulated by Australian federal, state and local governments with respect to environmental issues such as land reclamation, water quality, air quality, dust control, noise, planning issues (such as approvals to expand existing mines or to develop new mines) and health and safety issues. The Australian federal government retains control over the level of foreign investment and export approvals. Industrial relations are regulated under both federal and state laws. Australian state governments also require coal companies to post deposits or give other security against land which is being used for mining, with those deposits being returned or security released after satisfactory reclamation is completed.
Safe Work Australia (SWA). As part of a broader review of workplace exposure standards, SWA is currently considering a proposal to reduce the time weighted average (TWA) Workplace Exposure Standard (WES) for carbon dioxide (CO 2) in Australian coal mines from 12,500 ppm to 5,000 ppm. Currently there is a separate TWA for CO 2 in coal mines however SWA proposes to remove this to align with a general industry standard. If implemented, the change has the potential to affect underground mines operating in CO 2 rich coal seams, including the primary coal seam of the Company’s Metropolitan Mine. Importantly, a minimum three-year transition period applies for any change to standards.
Environment Protection and Biodiversity Conservation Amendment (Standards and Assurance) Bill 2021. On February 25, 2021 the Commonwealth Government introduced the Environment Protection and Biodiversity Conservation Amendment (Standards and Assurance) Bill 2021 into Parliament, which proposes amendments to the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) following the release of the Final Report of the Independent Review of the Act undertaken by Professor Graeme Samuel (the Samuel Review) that made 38 recommendations for short and long-term reforms, and ultimately calls for a complete overhaul of the existing legislative framework by 2022, to be undertaken in several tranches, with a strong focus on the setting of National Environmental Standards, assurance and compliance, data availability and management, and indigenous engagement. The bill responds to some of the recommendations for immediate reform made in the Samuel Review, and seeks to: establish a framework for the making, varying, revoking and application of National Environmental Standards; apply the National Environmental Standards to bilateral agreements with States and Territories; and establish an Environment Assurance Commissioner to monitor and audit bilateral agreements and other processes under the EPBC Act. The bill passed the Australian Parliament’s House of Representatives in June 2021 and will now be considered by the Australian Senate during its August sittings.
Native Title and Cultural Heritage. On February 3, 2021 the Native Title Act 1993 was amended largely directed at improving the efficiency of the native title system for all parties. The amendments confirm the validity of most section 31 right to negotiate agreements which might be invalid because of non-execution by any of the persons comprising the registered native title claimant following the Full Federal Court's decision in McGlade v Registrar National Native Title Tribunal. Other significant amendments include that: during the right to negotiate process the parties to section 31 agreements are now required to notify the National Native Title Tribunal of the existence of any ancillary agreements; new section 47C allows historical extinguishment to be disregarded on park areas including extinguishment by public works; and new section 24MD(6B)(f) creates a new 8 month objection period for the creation of a right to mine for the purpose of an infrastructure facility associated with mining and to some compulsory acquisitions of native title.
Global Climate
In the U.S., Congress has considered legislation addressing global climate issues and greenhouse gas emissions, but to date, no legislation directly affecting fossil fuel-fired powerplants has been signed into law. Congress did include climate legislation, the American Innovation and Manufacturing Act of 2020, within a large appropriations bill for the 2021 fiscal year. This legislation was enacted in December, 2020, and will require phasedown of the production and use of hydrofluorocarbons (HFCs) in the United States. While it is possible that the U.S. will adopt broader legislation in the future, the timing and specific requirements of any such legislation are uncertain.

Table of Contents
In the absence of new U.S. federal legislation, the EPA has taken steps to regulate greenhouse gas emissions pursuant to the CAA. In response to the U.S. Supreme Court ruling in Massachusetts v. EPA, 549 U.S. 497 (2007) the EPA commenced several rulemaking projects as described under “Regulatory Matters - U.S.” As described above, however, the EPA’s rules affecting existing fossil-fuel fired power plants (i.e. the ACE Rule and the EPA’s repeal of the CPP) were vacated and remanded back to the EPA by the D.C. Circuit Court of Appeals. Greenhouse gas requirements for new, reconstructed and modified fossil fuel fired power plants remain in effect.
Several changes in the New Source Review (NSR) program, a permitting plan under the CAA for new source construction and major modifications, have also been issued through guidance and rulemaking as described under “Regulatory Matters – U.S.” in the Company’s Annual Report on Form 10-K. The NSR program provides for the pre-construction review of new, reconstructed and modified stationary sources and results in determinations concerning the emission control technology that must be installed and operated at a source. Clean Air Act standards, known as new source performance standards, generally serve as a “floor” level of control for sources subject to NSR review; the final level of control is determined through the permitting process. In certain cases, performance standards or controls regarding greenhouse gas emissions may be required through the NSR process.
At the same time, a number of states in the U.S. have adopted programs to regulate greenhouse gas emissions. For example, 10 northeastern states (Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island and Vermont) entered into the Regional Greenhouse Gas Initiative (RGGI) in 2005, which is a mandatory cap-and-trade program to cap regional carbon dioxide emissions from power plants. Six mid-western states (Illinois, Iowa, Kansas, Michigan, Minnesota and Wisconsin) and one Canadian province have entered into the Midwestern Regional Greenhouse Gas Reduction Accord (MGGRA) to establish voluntary regional greenhouse gas reduction targets and develop a voluntary multi-sector cap-and-trade system to help meet the targets. It has been reported that, while the MGGRA has not been formally suspended, the participating states are no longer pursuing it. Seven western states (Arizona, California, Montana, New Mexico, Oregon, Utah and Washington) and four Canadian provinces entered into the Western Climate Initiative (WCI) in 2008 to establish a voluntary regional greenhouse gas reduction goal and develop market-based strategies to achieve emissions reductions. However, in November 2011, the WCI announced that six states had withdrawn from the WCI, leaving California and four Canadian provinces as the remaining members. Of those five jurisdictions, only California and Quebec have adopted greenhouse gas cap-and-trade regulations to date and both programs have begun operating. Many of the states and provinces that left WCI, RGGI and MGGRA, along with many that continue to participate, have joined the new North America 2050 initiative, which seeks to reduce greenhouse gas emissions and create economic opportunities in ways not limited to cap-and-trade programs. Separately, California has committed through Executive Order B-55-18 and SB 100 to 100 percent “clean energy” by 2045 and the state of Washington has passed legislation to commit to carbon neutrality by 2050.
Several other U.S. states have enacted legislation establishing greenhouse gas emissions reduction goals or requirements. In addition, several states have enacted legislation or have in effect regulations requiring electricity suppliers to use renewable energy sources to generate a certain percentage of power or that provide financial incentives to electricity suppliers for using renewable energy sources. Some states have initiated public utility proceedings that may establish values for carbon emissions.
Increasingly, both foreign and domestic banks, insurance companies and large investors are curtailing or ending their financial relationships with fossil fuel-related companies. This has had adverse impacts on the liquidity and operations of coal producers.
Peabody participated in the Department of Energy’s Voluntary Reporting of Greenhouse Gases Program until its suspension in May 2011, and Peabody regularly discloses in its annual Environmental, Social and Governance Report the quantity of emissions per ton of coal produced by the Company in the U.S. The vast majority of the Company’s emissions are generated by the operation of heavy machinery to extract and transport material at its mines and fugitive emissions from the extraction of coal.

The Kyoto Protocol, adopted in December 1997 by the signatories to the 1992 United Nations Framework Convention on Climate Change (UNFCCC), established a binding set of greenhouse gas emission targets for developed nations. The U.S. signed the Kyoto Protocol but it has never been ratified by the U.S. Senate. Australia ratified the Kyoto Protocol in December 2007 and became a full member in March 2008. There were discussions to develop a treaty to replace the Kyoto Protocol after the expiration of its commitment period in 2012, including at the UNFCCC conferences in Cancun (2010), Durban (2011), Doha (2012) and Paris (2015). At the Durban conference, an ad hoc working group was established to develop a protocol, another legal instrument or an agreed outcome with legal force under the UNFCCC, applicable to all parties. At the Doha meeting, an amendment to the Kyoto Protocol was adopted, which included new commitments for certain parties in a second commitment period, from 2013 to 2020. In December 2012, Australia signed on to the second commitment period. During the UNFCCC conference in Paris, France in late 2015, an agreement was adopted calling for voluntary emissions reductions contributions after the second commitment period ends in 2020 (the Paris Agreement). The agreement was entered into force on November 4, 2016 after ratification and execution by more than 55 countries, including Australia, that account for at least 55% of global greenhouse gas emissions.
In January 2021, the U.S. reentered the Paris Agreement by accepting the agreement and all of its articles and clauses, after having announced its withdrawal from the agreement in November 2019. In April 2021, the U.S. announced its own Nationally Determined Contribution (NDC) with respect to the Paris Agreement. The NDC is voluntary and would aim to cut carbon dioxide output by 50% to 52% compared with 2005 levels by 2030. Recently, the U.S. has announced the goal of a completely emissions-free power grid by 2035, but has not provided specificity for a regulatory framework to achieve that goal. The Company anticipates a series of executive actions and/or orders from the current presidential administration aimed at curbing emission levels as well as associated rulemaking using the CAA and potentially other statutory authorities.
In October 2017, the Australian Federal Government released a plan aimed at delivering an affordable and reliable energy system that meets Australia’s international commitments to emissions reduction. The plan was referred to as the National Energy Guarantee (NEG) and was aimed at changing the National Electricity Market and associated legislative framework. The NEG was abandoned by the Australian government in September 2018. Following the outcome of the federal election in May 2019, the federal government confirmed it will not revive the former NEG policy. Instead, the government will pursue a new energy and climate change policy, which includes a $2 billion Australian dollars investment in projects to bring down Australia's greenhouse gas emissions. The Climate Solutions Fund is an extension of the former Emissions Reduction Fund. The government has confirmed that it remains committed to meeting Australia’s Paris Agreement targets but has not formally committed to net zero emissions by 2050 with the focus of energy policy on the use of technology to accelerate the development and commercialization of low and zero emissions technologies and driving down electricity prices.
The enactment of future laws or the passage of regulations regarding emissions from the use of coal by the U.S., some of its states or other countries, or other actions to limit such emissions, could result in electricity generators switching from coal to other fuel sources. Further, policies limiting available financing for the development of new coal-fueled power stations could adversely impact the global demand for coal in the future. The potential financial impact on the Company of such future laws, regulations or other policies will depend upon the degree to which any such laws or regulations force electricity generators to diminish their reliance on coal as a fuel source. That, in turn, will depend on a number of factors, including the specific requirements imposed by any such laws, regulations or other policies, the time periods over which those laws, regulations or other policies would be phased in, the state of development and deployment of CCUS technologies as well as acceptance of CCUS technologies to meet regulations and the alternative uses for coal. Higher-efficiency coal-fired power plants may also be an option for meeting laws or regulations related to emissions from coal use. Several countries, including major coal users such as China, India and Japan, included using higher-efficiency coal-fueled power plants in their plans under the Paris Agreement. From time to time, Peabody attempts to analyze the potential impact on the Company of as-yet-unadopted, potential laws, regulations and policies. Such analyses require that Peabody make significant assumptions as to the specific provisions of such potential laws, regulations and policies which sometimes show that if implemented in the manner assumed by the analyses, the potential laws, regulations and policies could result in material adverse impacts on its operations, financial condition or cash flow. The Company does not believe that such analyses reasonably predict the quantitative impact that future laws, regulations or other policies may have on its results of operations, financial condition or cash flows.

Liquidity and Capital Resources
Overview
The Company’s primary source of cash is proceeds from the sale of its coal production to customers. The Company has also generated cash from the sale of non-strategic assets, including coal reserves and surface lands, and, from time to time, borrowings under its credit facilities and the issuance of securities. The Company’s primary uses of cash include the cash costs of coal production, capital expenditures, coal reserve lease and royalty payments, debt service costs, capital and operating lease payments, postretirement plans, take-or-pay obligations, post-mining reclamation obligations, and selling and administrative expenses. The Company has also used cash for dividends, share repurchases and early debt retirements.
Any future determinations to return capital to stockholders, such as dividends or share repurchases will depend on a variety of factors, including the restrictions set forth under the Company’s debt and surety agreements, its net income or other sources of cash, liquidity position and potential alternative uses of cash, such as internal development projects or acquisitions, as well as economic conditions and expected future financial results. The Company’s ability to early retire debt, declare dividends or repurchase shares in the future will depend on its future financial performance, which in turn depends on the successful implementation of its strategy and on financial, competitive, regulatory, technical and other factors, general economic conditions, demand for and selling prices of coal and other factors specific to its industry, many of which are beyond the Company’s control. The Company has presently suspended the payment of dividends and share repurchases, as discussed in Part II, Item 2. “Unregistered Sales of Equity Securities and Use of Proceeds.”
Liquidity
As of June 30, 2021, the Company’s cash balances totaled $548.3 million, including approximately $366 million held by U.S. subsidiaries and $153 million held by Australian subsidiaries, approximately $102 million of which was held by the subsidiaries that conduct the operations of its Wilpinjong Mine. The remaining cash balance was held by other foreign subsidiaries in accounts predominantly domiciled in the U.S. A significant majority of the cash held by the Company’s foreign subsidiaries is denominated in U.S. dollars. This cash is generally used to support non-U.S. liquidity needs, including capital and operating expenditures in Australia.
The Company’s available liquidity declined from $728.7 million as of December 31, 2020 to $564.1 million as of June 30, 2021. Available liquidity, which excluded $13.6 million of restricted cash as of June 30, 2021, was comprised of the following:

|  |  | June 30, 2021 |  | December 31, 2020

The Company’s Indebtedness was significantly impacted subsequent to December 31, 2020 as a result of various agreements and transactions described below.
Refinancing and Related Transactions
During the fourth quarter of 2020 and the first quarter of 2021, the Company entered into a series of interrelated agreements with its surety bond providers, the revolving lenders under its credit agreement and certain holders of its senior secured notes to extend a significant portion of its near-term debt maturities to December 2024 and to stabilize collateral requirements for its existing surety bond portfolio. Such agreements and related activities are described below.
Organizational Realignment
In July and August 2020, the Company effected certain changes to its corporate structure in contemplation of a debt-for-debt exchange, which included, among other steps, the formation of certain wholly-owned subsidiaries (the Co-Issuers). In connection with the change in structure, the Company’s subsidiary which owns and operates its Wilpinjong Mine in Australia became a subsidiary of the Co-Issuers. The Co-Issuers and the Wilpinjong subsidiary were designated as unrestricted subsidiaries under the Company’s credit agreement (Credit Agreement) and its senior notes’ indenture (the Existing Indenture). In connection with these actions, the Company contributed $100.0 million to the Co-Issuers to provide the Wilpinjong Mine with operating liquidity and address its near-term capital needs.
Surety Agreement
In November 2020, the Company entered into a surety transaction support agreement (Surety Agreement) with the providers of 99% of its surety bond portfolio (Participating Sureties) to resolve previous collateral demands made by the Participating Sureties. In accordance with the Surety Agreement, the Company initially provided $75.0 million of collateral, in the form of letters of credit.
Upon completion of the Refinancing Transactions, as defined below, other provisions of the Surety Agreement became effective. In particular, the Company granted second liens on $200.0 million of certain mining equipment and will post an additional $25.0 million of collateral per year from 2021 through 2024 for the benefit of the Participating Sureties. The collateral postings may also further increase to the extent the Company generates more than $100.0 million of free cash flow (as defined in the Surety Agreement) in any twelve-month period or has cumulative asset sales in excess of $10.0 million, as of the last quarter end during the term of the agreement. Further, the Participating Sureties have agreed to a standstill through the earlier of December 31, 2025, or the maturity of the Credit Agreement (currently March 31, 2025), during which time, the Participating Sureties will not demand any additional collateral, draw on letters of credit posted for the benefit of themselves or cancel any existing surety bond. The Company will not pay dividends or make share repurchases during the standstill period, unless otherwise agreed between parties.

Refinancing Transactions
On January 29, 2021 (the Settlement Date), the Company completed a series of transactions (collectively, the Refinancing Transactions) to, among other things, provide it with maturity extensions and covenant relief, while allowing it to maintain near-term operating liquidity and financial flexibility. The Refinancing Transactions included a senior notes exchange and related consent solicitation, a revolving credit facility exchange and various amendments to its existing debt agreements, as summarized below.
Exchange Offer
On the Settlement Date, the Company settled an exchange offer (Exchange Offer) pursuant to which $398.7 million aggregate principal amount of its 6.000% Senior Secured Notes due March 2022 (2022 Notes) were validly tendered, accepted by the Company and exchanged for aggregate consideration consisting of (a) $193.9 million aggregate principal amount of new 10.000% Senior Secured Notes due 2024 issued by the Co-Issuers (Co-Issuer Notes), (b) $195.1 million aggregate principal amount of new 8.500% Senior Secured Notes due 2024 issued by Peabody (Peabody Notes), and (c) a cash payment of approximately $9.4 million. In connection with the settlement of the Exchange Offer, the Company also paid early tender premiums totaling $4.0 million in cash. Refer to Note 11. “Long-term Debt” for additional information associated with the Co-Issuer Notes and the Peabody Notes.
As required under the Exchange Offer, the Company purchased $22.4 million of the Peabody Notes at 80% of their accreted value, plus accrued and unpaid interest, during the first quarter of 2021 and recognized a related net gain on extinguishment of $3.5 million.
Consent Solicitation
Concurrently with the Exchange Offer, the Company solicited consents from holders of the 2022 Notes to certain proposed amendments to the Existing Indenture to (i) eliminate substantially all of the restrictive covenants, certain events of default applicable to the 2022 Notes and certain other provisions contained in the Existing Indenture and (ii) release the collateral securing the 2022 Notes and eliminate certain other related provisions contained in the Existing Indenture. The Company received the requisite consents from holders of the 2022 Notes and entered into a supplemental indenture to the Existing Indenture, which became operative on January 29, 2021.
Revolver Transactions
In connection with the Refinancing Transactions, the Company restructured the revolving loans under the Credit Agreement by (i) making a pay down of revolving loans thereunder in the aggregate amount of $10.0 million, (ii) the Co-Issuers incurring $206.0 million of term loans under a credit agreement, dated as of the Settlement Date (Co-Issuer Term Loans, Co-Issuer Term Loan Agreement), (iii) Peabody entering into a letter of credit facility (the Company LC Agreement), and (iv) amending the Credit Agreement (collectively, the Revolver Transactions).
The Co-Issuer Term Loans mature on December 31, 2024 and bear interest at a rate of 10.00% per annum.
On the Settlement Date, the Company entered into the Company LC Agreement with the revolving lenders party to the Credit Agreement, pursuant to which the Company obtained a $324.0 million letter of credit facility under which its existing letters of credit under the Credit Agreement were deemed to be issued. The commitments under the Company LC Agreement mature on December 31, 2024. Undrawn letters of credit under the Company LC Agreement bear interest at 6.00% per annum and unused commitments are subject to a 0.50% per annum commitment fee.
In connection with the Revolver Transactions, the Company amended the Credit Agreement to make certain changes in consideration of the Company LC Agreement. After giving effect to the Revolver Transactions, there remain no revolving commitments or revolving loans under the Credit Agreement and the first lien net leverage ratio covenant was eliminated. The Company LC Agreement requires that the Company’s restricted subsidiaries maintain minimum aggregate liquidity of $125.0 million at the end of each quarter through December 31, 2024. As such, liquidity attributable to the Co-Issuers, its subsidiaries and other unrestricted subsidiaries is excluded from the calculation. Liquidity calculated in this manner amounted to $444.9 million at June 30, 2021.

Table of Contents
The indenture which governs the Peabody Notes and the Company LC Agreement allow the Company to make open market debt repurchases, subject to certain limitations, including, but not limited to: (i) the Company’s unrestricted subsidiaries’ liquidity must be greater than or equal to $200.0 million after giving effect to such repurchases and (ii) for every $4 of principal repurchased in any fiscal quarter, the Company must make an offer on a pro rata basis to purchase $1 of principal amount of debt from holders of the Peabody Notes and the priority lien obligations under the Company LC Agreement within 30 days of the end of such fiscal quarter at a price equal to the weighted average repurchase price paid over that quarter (Mandatory Repurchase Offer).
Other Debt Financing
The Refinancing Transactions did not significantly impact the Company’s existing senior secured term loan under the Credit Facility (Senior Secured Term Loan), or its $500.0 million of 6.375% senior secured notes due March 2025 (2025 Notes), but these debt instruments were impacted by subsequent financing transactions described below. The term loan requires quarterly principal payments of $1.0 million and periodic interest payments, currently at LIBOR plus 2.75%, through December 2024 with the remaining balance due in March 2025. The senior secured notes require semi-annual interest payments each March 31 and September 30 until maturity.
The Company’s debt agreements impose various restrictions and limits on certain categories of payments that the Company may make, such as those for dividends, investments, and stock repurchases. The Company is also subject to customary affirmative and negative covenants. The Company was compliant with all covenants under its debt agreements including the minimum liquidity covenant under the Company LC Agreement at June 30, 2021.
Subsequent Financing Transactions
Subsequent to the Refinancing Transactions, the Company completed a series of financing transactions intended to improve its capital structure.
In June 2021, the Company announced an at-the-market equity offering program pursuant to which the Company could offer and sell up to 12.5 million shares of its common stock. Such sales are allowed using methods permissible under Rule 415 of the Securities Act. The shares are offered and sold pursuant to the Company’s Registration Statement on Form S-3, which was declared effective by the Securities and Exchange Commission on April 23, 2021, as supplemented by a prospectus supplement dated June 4, 2021, relating to the offer and sale of the shares. During the three months ended June 30, 2021, the Company sold approximately 8.1 million shares for net cash proceeds of $65.1 million. Subsequent to June 30, 2021, the Company settled sales of an additional 2.7 million shares for net proceeds of $21.5 million.
During the three months ended June 30, 2021, the Company retired $18.0 million of Peabody Notes, $17.4 million of 2025 Notes and $17.8 million of its Senior Secured Term Loan primarily through various open market purchases at an aggregate cost of $39.2 million. The Company recorded a gain on early debt extinguishment of $11.9 million, net of debt issuance costs and original issue discount related to the retired debt of $2.1 million.
Also during the three months ended June 30, 2021, the Company completed multiple bilateral transactions with holders of the 2022 Notes in which the Company issued an aggregate 4.5 million shares of its common stock in exchange for $30.9 million aggregate principal amount of the 2022 Notes. Based upon the fair value of the Company’s common stock at the respective settlement dates, the Company recorded a net loss on early debt extinguishment of $0.1 million in connection with the transactions. The issuance of shares of common stock in exchange for the 2022 Notes was exempt from registration under the Securities Act, on the basis that the exchange was completed with existing holders of the Company’s securities, and no commission or other remuneration was paid or given for soliciting the exchange.
The Company also reached agreements to retire an additional $49.5 million of aggregate principal, which will settle subsequent to June 30, 2021. This included $44.0 million of its Senior Secured Term Loan due 2025 and $1.5 million of 2025 Notes through similar open market purchases for an aggregate cost of $30.2 million, and by issuing an aggregate 0.5 million shares of its common stock in exchange for $4.0 million aggregate principal amount of the 2022 Notes in a similar manner noted above. Such amounts are reflected within the current portion of long-term debt in the accompanying condensed consolidated balance sheets at June 30, 2021.
As a result of the Company’s open market purchases of its debt during the three months ended June 30, 2021, on July 7, 2021, the Company announced a Mandatory Repurchase Offer of up to $13.3 million of its 2024 Peabody Notes, at 73.840% of their aggregate accreted value, plus accrued and unpaid interest, and a concurrent repurchase offer of priority lien obligations under the Company LC Agreement. The offers expire on August 6, 2021, unless extended by the Company.

Table of Contents
Considering the Refinancing Transactions and the subsequent financing transactions described above, the Company expects to incur approximately $190 million of interest expense, including approximately $40 million of non-cash interest expense, during the year ended December 31, 2021.
Accounts Receivable Securitization Program
As described in Note 16. “Financial Instruments and Other Guarantees” of the accompanying unaudited condensed consolidated financial statements, the Company entered into an accounts receivable securitization program during 2017 which currently matures in 2022. The Company intends to renew the facility prior to maturity. The program provides for up to $250.0 million in funding, limited to the availability of eligible receivables, accounted for as a secured borrowing. Funding capacity under the program may also be utilized for letters of credit in support of other obligations. At June 30, 2021, the Company h a d no outstanding borrowings and $125.5 million of letters of credit issued under the program, which were primarily in support of portions of the Company’s reclamation obligations. The Company had $13.6 million of cash collateral posted under the Securitization Program at June 30, 2021 due to outstanding letters of credit temporarily exceeding the balance of eligible receivables at quarter-end.
Capital Requirements
For 2021, the Company is targeting capital expenditures of approximately $200 million, which includes approximately $100 million for ongoing extension projects primarily related to its Seaborne Thermal Mining segment. The Company has no substantial future payment requirements under U.S. federal coal reserve leases.
Contractual Obligations
There were no material changes to the Company’s contractual obligations from the information previously provided in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.
Cash Flows and Free Cash Flow
The following table summarizes the Company’s cash flows for the six months ended June 30, 2021 and 2020, as reported in the accompanying unaudited condensed consolidated financial statements. Free Cash Flow is a financial measure not recognized in accordance with U.S. GAAP. Refer to the “Reconciliation of Non-GAAP Financial Measures” section above for definitions and reconciliations to the most comparable measures under U.S. GAAP.

Table of Contents
Operating Activities. The decrease in net cash used in operating activities for the six months ended June 30, 2021 compared to the same period in the prior year was driven by a year-over-year increase in cash generated by Company’s mining operations, partially offset by an unfavorable change in net cash flows associated with its working capital ($67.2 million).
Investing Activities. The decrease in net cash used in investing activities for the six months ended June 30, 2021 compared to the same period in the prior year was driven by lower advances to related parties and joint ventures, on a net basis ($34.8 million).
Financing Activities. The decrease in net cash provided by financing activities for the six months ended June 30, 2021 compared to the same period in the prior year was driven by $300.0 million of revolving loan borrowings in the prior year, higher repayments of debt principal ($73.2 million) and payments for deferred financing costs ($22.5 million) in the current year, partially offset by $65.1 million proceeds from the issuance of common stock in the current year.
Off-Balance-Sheet Arrangements
In the normal course of business, the Company is a party to various guarantees and financial instruments that carry off-balance-sheet risk and are not reflected in the accompanying condensed consolidated balance sheets. At June 30, 2021, such instruments inc lude d $1,555.0 million of surety bonds and $435.4 million o f letters of credit. Such financial instruments provide support for its reclamation bonding requirements, lease obligations, insu rance policies and various other performance guarantees. The Company periodically evaluates the instruments for on-balance-sheet treatment based on the amount of exposure under the instrument and the likelihood of required performance. The Company does not expect any material losses to result from these guarantees or off-balance-sheet instruments in excess of liabilities provided for in its condensed consolidated balance sheets.
As of June 30, 2021, the Company was party to financial instruments with off-balance-sheet risk in support of the following obligations:

| Reclamation |  | Health and welfare (1) |  | Contract performance (2) |  | Leased property and equipment |  | Other (3) |  | Total

(1) Obligations include pension and healthcare plans, workers’ compensation, and property and casualty insurance
(2) Obligations pertain to customer and vendor contracts
(3) Obligations primarily pertain to the disturbance or alteration of public roadways in connection with the Company’s mining activities that is subject to future restoration
(4) Serve as collateral for certain surety bonds at the request of surety bond providers. The Company has also posted $5.2 million in incremental collateral directly with the beneficiary that is not supported by a surety bond.
Financial assurances associated with new reclamation bonding requirements, surety bonds or other obligations may require additional collateral in the form of cash or letters of credit causing a decline in the Company’s liquidity.

Table of Contents
As described in Note 16. “Financial Instruments and Other Guarantees” in the accompanying unaudited condensed consolidated financial statements, the Company is required to provide various forms of financial assurance in support of its mining reclamation obligations in the jurisdictions in which it operates. Such requirements are typically established by statute or under mining permits. Historically, such assurances have taken the form of third-party instruments such as surety bonds, bank guarantees and letters of credit, as well as self-bonding arrangements in the U.S. Self-bonding in the U.S. has become increasingly restricted in recent years, leading to the Company’s increased usage of surety bonds and similar third-party instruments. This change in practice has had an unfavorable impact on its liquidity due to increased collateral requirements and surety and related fees.
At June 30, 2021, the Company had total asset retirement obligations of $741.8 million which were backed by a combination of surety bonds, bank guarantees and letters of credit.
Bonding requirement amounts may differ significantly from the re lated asset retirement obligation because such requirements are calculated under the assumption that reclamation begins currently, whereas the Company’s accounting liabilities are discounted from the end of a mine’s economic life (when final reclamation work would begin) to the balance sheet date.
Guarantees and Other Financial Instruments with Off-Balance-Sheet Risk. See Note 16. “Financial Instruments and Other Guarantees” in the Company’s unaudited condensed consolidated financial statements for a discussion of its accounts receivable securitization program and guarantees and other financial instruments with off-balance-sheet risk.
Critical Accounting Policies and Estimates
The Company’s discussion and analysis of its financial condition, results of operations, liquidity and capital resources is based upon its financial statements, which have been prepared in accordance with U.S. GAAP. The Company is also required under U.S. GAAP to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, the Company evaluates its estimates. The Company bases its estimates on historical experience and on various other assumptions that it believes are 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.
At June 30, 2021, the Company identified certain assets with an aggregate carrying value of approximately $1.2 billion in its Seaborne Metallurgical Mining, Powder River Basin Mining, Other U.S. Thermal Mining and Corporate and Other segments whose recoverability is most sensitive to coal pricing, cost pressures, customer demand, customer concentration risk and future economic viability. The Company conducted a review of those assets for recoverability as of June 30, 2021 and determined that no impairment charges were necessary as of that date.
The Company’s critical accounting policies are discussed in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in its Annual Report on Form 10-K for the year ended December 31, 2020. The Company’s critical accounting policies remain unchanged at June 30, 2021.
Newly Adopted Accounting Standards and Accounting Standards Not Yet Implemented
See Note 2. “Newly Adopted Accounting Standards and Accounting Standards Not Yet Implemented” to the Company’s unaudited condensed consolidated financial statements for a discussion of newly adopted accounting standards and accounting standards not yet implemented.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.
Foreign Currency Risk
The Company has historically utilized currency forwards and options to hedge currency risk associated with anticipated Australian dollar expenditures. The accounting for these derivatives is discussed in Note 7. “Derivatives and Fair Value Measurements” to the accompanying unaudited condensed consolidated financial statements. As of June 30, 2021, the Company had currency options outstanding with an aggregate notional amount of $580.0 million Australian dollars to hedge currency risk associated with anticipated Australian dollar expenditures over the nine-month period ending March 31, 2022. Assuming the Company had no foreign currency hedging instruments in place, its exposure in operating costs and expenses due to a $0.10 change in the Australian dollar/U.S. dollar exchange rate is approximately $130 million for the next twelve months. Based upon the Australian dollar/U.S. dollar exchange rate at June 30, 2021, the currency option contracts outstanding at that date would limit the Company’s net exposure to a $0.10 unfavorable change in the exchange rate to approximately $104 million for the next twelve months.
Other Non-Coal Trading Activities — Diesel Fuel Price Risk
Diesel Fuel Hedges. Previously, the Company managed price risk of the diesel fuel used in its mining activities through the use of derivatives, primarily swaps. As of June 30, 2021, the Company did not have any diesel fuel derivative instruments in place. The Company also manages the price risk of diesel fuel through the use of cost pass-through contacts with certain customers.
The Company expects to consume 75 to 85 million gallons of diesel fuel during the next twelve months. A $10 per barrel change in the price of crude oil (the primary component of a refined diesel fuel product) would increase or decrease its annual diesel fuel costs by approximately $20 million based on its expected usage.
Item 4. Controls and Procedures.
The Company’s disclosure controls and procedures are designed to, among other things, provide reasonable assurance that material information, both financial and non-financial, and other information required under the securities laws to be disclosed is accumulated and communicated to senior management, including its principal executive and financial officers, on a timely basis. The Company’s Chief Executive Officer and Chief Financial Officer have evaluated its disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of June 30, 2021, and concluded that such controls and procedures were effective to provide reasonable assurance that the desired control objectives were achieved. Additionally, there have been no changes to the Company’s internal control over financial reporting during the most recent fiscal quarter that materially affected, or are reasonably likely to materially affect, its internal control over financial reporting.
PART II - OTHER INFORMATION
Item 1. Legal Proceedings.
The Company is subject to various legal and regulatory proceedings.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.
Dividends
The Company suspended dividends in 2020. As more fully described within “Liquidity and Capital Resources” of Part I, Item 2. “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” during the fourth quarter of 2020, the Company entered into transaction support agreements with its surety bond providers which prohibit the payment of dividends through the earlier of December 31, 2025, or the maturity of the Credit Agreement (currently March 31, 2025) unless otherwise agreed to by the parties to the agreements. Additionally, restrictive covenants in its credit facility and in the indentures governing its senior secured notes also limit the Company’s ability to pay cash dividends.
Share Repurchase Program
On August 1, 2017, the Company announced that its Board of Directors authorized a share repurchase program to allow repurchases of up to $500 million of the then outstanding shares of its common stock and/or preferred stock (Repurchase Program). On April 25, 2018, the Company announced that the Board authorized the expansion of the Repurchase Program to $1.0 billion. On October 30, 2018, the Company announced that the Board authorized an additional expansion of the Repurchase Program to $1.5 billion. The Repurchase Program does not have an expiration date and may be discontinued at any time. Through June 30, 2021, the Company has repurchased 41.5 million shares of its common stock for $1,340.3 million, which included commissions paid of $0.8 million, leaving $160.5 million available for share repurchase under the Repurchase Program.
The Company suspended share repurchases in 2019, and similar to the payment of dividends as described above, the same agreements with its surety bond providers prohibit share repurchases through the earlier of December 31, 2025, or the maturity of the Credit Agreement (currently March 31, 2025) unless otherwise agreed to by the parties to the agreements. Additionally, restrictive covenants in its credit facility and in the indentures governing its senior secured notes also limit the Company’s ability to repurchase shares. Prior to the suspension, repurchases were made at the Company’s discretion. The specific timing, price and size of purchases depended upon the share price, general market and economic conditions and other considerations, including compliance with various debt agreements in effect at the time the repurchases were made.
Issuances of Equity Securities
In June 2021, the Company announced an at-the-market equity offering program pursuant to which the Company could offer and sell up to 12.5 million shares of its common stock. Such sales are allowed using methods permissible under Rule 415 of the Securities Act. The shares are offered and sold pursuant to the Company’s Registration Statement on Form S-3, which was declared effective by the Securities and Exchange Commission on April 23, 2021, as supplemented by a prospectus supplement dated June 4, 2021, relating to the offer and sale of the shares. During the three months ended June 30, 2021, the Company sold approximately 8.1 million shares for net cash proceeds of $65.1 million. Subsequent to June 30, 2021, the Company settled sales of an additional 2.7 million shares for net proceeds of $21.5 million.
Also during the three months ended June 30, 2021, the Company completed multiple bilateral transactions with holders of the 2022 Notes in which the Company issued an aggregate 4.5 million shares of its common stock in exchange for $30.9 million aggregate principal amount of the 2022 Notes. The issuance of shares of common stock in exchange for the 2022 Notes was exempt from registration under the Securities Act, on the basis that the exchange was completed with existing holders of the Company’s securities, and no commission or other remuneration was paid or given for soliciting the exchange. Subsequent to June 30, 2021, the Company issued an aggregate 0.5 million shares of its common stock in exchange for $4.0 million aggregate principal amount of the 2022 Notes in a similar manner as noted above.
Share Relinquishments
The Company routinely allows employees to relinquish common stock to pay estimated taxes upon the vesting of restricted stock units and the payout of performance units that are settled in common stock under its equity incentive plans. The value of common stock tendered by employees is determined based on the closing price of the Company’s common stock on the dates of the respective relinquishments.
