PEABODY ENERGY CORPORATION

(DEBTOR-IN-POSSESSION)

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(1) Basis of Presentation

The condensed consolidated financial statements include the accounts of Peabody Energy Corporation and its affiliates (the Company or Peabody). Interests in subsidiaries controlled by the Company are consolidated with any outside shareholder interests reflected as noncontrolling interests, except when the Company has an undivided interest in an unincorporated 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. As discussed below in Note 2. "Newly Adopted Accounting Standards and Accounting Standards Not Yet Implemented," prior year amounts of deferred financing costs have been reclassified to conform with the new standard.

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, 2015. 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, 2015 has been derived from the Company’s audited consolidated balance sheet at that date. The Company's results of operations for the three and nine months ended September 30, 2016 are not necessarily indicative of the results that may be expected for future quarters or for the year ending December 31, 2016.

Pursuant to the authorization provided at a special meeting of the Company's stockholders held on September 16, 2015, the Company completed a 1-for-15 reverse stock split of the shares of the Company’s common stock on September 30, 2015 (the Reverse Stock Split). As a result of the Reverse Stock Split, every 15 shares of issued and outstanding common stock were combined into one issued and outstanding share of Common Stock, without any change in the par value per share. No fractional shares were issued as a result of the Reverse Stock Split and any fractional shares that would otherwise have resulted from the Reverse Stock Split were paid in cash. The Reverse Stock Split reduced the number of shares of common stock outstanding from approximately 278 million shares to approximately 19 million shares. The number of authorized shares of common stock was also decreased from 800 million shares to 53.3 million shares. The Company's common stock began trading on a reverse stock split-adjusted basis on the New York Stock Exchange (NYSE) on October 1, 2015. All share and per share data included in this report has been retroactively restated to reflect the Reverse Stock Split. Since the par value of the common stock remained at $0.01 per share, the value for "Common stock" recorded to the Company's condensed consolidated balance sheets has been retroactively reduced to reflect the par value of restated outstanding shares, with a corresponding increase to "Additional paid-in capital."

The Company has classified items within discontinued operations in the unaudited condensed consolidated financial statements for disposals (by sale or otherwise) that have occurred prior to January 1, 2015 when the operations and cash flows of a disposed component of the Company were eliminated from the ongoing operations of the Company as a result of the disposal and the Company no longer had any significant continuing involvement in the operation of that component.

Filing Under Chapter 11 of the United States Bankruptcy Code

On April 13, 2016 (the Petition Date), Peabody and a majority of its wholly owned domestic subsidiaries as well as one international subsidiary in Gibraltar (the Filing Subsidiaries, and together with Peabody, the Debtors) filed voluntary petitions for reorganization (the petitions collectively, the Bankruptcy Petitions) under Chapter 11 of Title 11 of the U.S. Code (the Bankruptcy Code) in the United States Bankruptcy Court for the Eastern District of Missouri (the Bankruptcy Court). The Company’s Australian operations and other international subsidiaries are not included in the filings. The Debtors' Chapter 11 cases (collectively, the Chapter 11 Cases) are being jointly administered under the caption In re Peabody Energy Corporation, et al., Case No. 16-42529 (Bankr. E.D. Mo.). The Debtors continue to operate their businesses as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.

PEABODY ENERGY CORPORATION

(DEBTOR-IN-POSSESSION)

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

The filings of the Bankruptcy Petitions constituted an event of default under the Company’s prepretition credit agreement as well as the indentures governing certain of the Company’s debt instruments, as further described in Note 13. "Current and Long-term Debt" to the condensed consolidated financial statements, and all unpaid principal and accrued and unpaid interest due thereunder became immediately due and payable. Any efforts to enforce such payment obligations are automatically stayed as a result of the Bankruptcy Petitions and the creditors' rights of enforcement are subject to the applicable provisions of the Bankruptcy Code.

Additionally, on the Petition Date, the NYSE determined that Peabody’s common stock was no longer suitable for listing pursuant to Section 8.02.01D of the NYSE’s Listed Company Manual, and trading in the Company’s common stock was suspended. The Company's common stock began trading on the OTC Pink Sheets marketplace under the symbol BTUUQ on April 14, 2016. Following the Petition Date, the NYSE formally de-listed the Company's common stock.

On April 14, 2016, the Bankruptcy Court approved several motions (First Day Motions), including motions (i) authorizing the Debtors to pay prepetition wages and benefits for its workforce (Employee Motion), in part, (ii) prohibiting utilities from discontinuing service and authorizing the Debtors to provide adequate assurance deposits, (iii) authorizing the Debtors to pay prepetition obligations to certain critical vendors on an interim basis (Critical Vendor Motion), (iv) authorizing the Debtors to maintain their existing cash management system on an interim basis (Cash Management Motion), (v)  authorizing certain Debtors to continue selling and contributing receivables and related rights pursuant to a securitization facility on an interim basis (Securitization Motion) and (vi) authorizing the Debtors to enter into an $800 million debtor-in-possession financing facility (DIP Credit Agreement) on an interim basis (DIP Motion).

Pursuant to Section 362 of the Bankruptcy Code, the filing of the Bankruptcy Petitions automatically stayed most actions against the Debtors, including actions to collect indebtedness incurred prior to the Petition Date or to exercise control over the Debtors’ property. Subject to certain exceptions under the Bankruptcy Code, the filing of the Debtors’ Chapter 11 Cases also automatically stayed the continuation of most legal proceedings, including certain of the third party litigation matters described in Note 19. "Commitments and Contingencies" and Note 20. "Matters Related to the Bankruptcy of Patriot Coal Corporation" of this report or the filing of other actions against or on behalf of the Debtors or their property to recover on, collect or secure a claim arising prior to the Petition Date or to exercise control over property of the Debtors’ bankruptcy estates, unless and until the Bankruptcy Court modifies or lifts the automatic stay as to any such claim. Notwithstanding the general application of the automatic stay described above, governmental authorities may determine to continue actions brought under their police and regulatory powers.

The U.S. Trustee for the Eastern District of Missouri filed a notice appointing an official committee of unsecured creditors (the Creditors' Committee) on April 29, 2016. The Creditors’ Committee represents all unsecured creditors of the Debtors and has a right to be heard on all matters that come before the Bankruptcy Court.

On May 17, 2016, the Bankruptcy Court approved various of the First Day Motions on a final basis, including the Employee Motion, Critical Vendor Motion, Cash Management Motion, Securitization Motion and DIP Motion. At the May 17 hearing, the Bankruptcy Court also approved various motions (i) authorizing the Debtors’ retention of various professionals, (ii) establishing procedures for the retention of ordinary course professionals, (iii) establishing procedures for the sale of de minimis assets and (iv)  authorizing the Debtors to consummate the sale of the Debtors’ equity interests in Lively Grove Energy Partners, LLC, a Debtor, and dismissing Lively Grove Energy Partners, LLC’s current chapter 11 case.

On May 20, 2016, the Debtors filed a complaint and request for declaratory judgment, as required by the terms of the DIP Credit Agreement, against Citibank, N.A. (in its capacity as Administrative Agent under the Debtors' prepetition secured credit agreement), among others, regarding the extent of certain collateral and secured claims of certain prepetition creditors (the CNTA Adversary Proceeding).

On June 13, 2016, Citibank, N.A. filed an answer and counter-claim for declaratory judgment.  On June 14, 2016, two motions to intervene were filed, one from the Creditors' Committee and another from a group of creditors holding $1.65 billion in face value of the Company's Senior Notes (as indicated in their motion). The intervention motions were granted on July 7, 2016.

On June 15, 2016, the Bankruptcy Court approved several motions, including motions that (i)  established deadlines for the filing of certain proofs of claim, approved the form and manner of notice thereof, and (ii)  established a key employee retention program. At this hearing, the Bankruptcy Court also approved the Debtors' retention of various professionals, and the Creditors’ Committee's retention of various professionals.

On August 22, 2016, the Debtors filed a motion regarding a settlement agreement that the Debtors reached with regulators in Illinois concerning the Debtors' reclamation bonding in that state (the Illinois Self-Bonding Stipulation). On September 1, 2016, (i) the Debtors filed a motion to establish claims objection procedures (the Claims Objection Procedures Motion) and (ii) the Bankruptcy Court entered (a) a stipulation and consent order by and between the Debtors and certain environmental groups concerning pending litigation brought by the environmental groups and (b) an order confirming the Debtors' authority to share confidential agreements with their restructuring advisors.

On September 15, 2016, the Bankruptcy Court granted several motions, including the Claims Objections Procedures Motion and the Illinois Self-Bonding Stipulation. The Bankruptcy Court entered orders approving these motions on September 15, 2016 and September 16, 2016, respectively. On September 16, 2016, the Debtors filed two omnibus objections to certain proofs of claim.

On September 8, 2016, the Debtors filed an objection to a claim asserted by the United Mine Workers of America 1974 Pension Plan and Trust (UMWA Plan). On September 26, 2016, the UMWA Plan filed a motion for relief from the automatic stay, seeking to allow arbitration between the Debtors and the UMWA Plan to resume outside of the Bankruptcy Court's jurisdiction. On October 7, 2016, the UMWA Plan filed a motion to continue the hearing on the Debtors' objection to the UMWA Plan's proof of claim until January 2017.

On September 30, 2016, numerous professionals retained by the Debtors and the Creditors’ Committee filed their first interim fee applications.

On October 11, 2016, the Bankruptcy Court approved a stipulation and agreed order filed by the Debtors seeking the authority to enter into that certain Amendment No. 4 and Consent Under Superpriority Secured Debtor-in-Possession Credit Agreement (the DIP Amendment). The DIP Amendment modifies certain of the milestones under the DIP Credit Agreement, including (i) a modification to the deadline by which the Bankruptcy Court shall enter an order determining the issues being adjudicated in the CNTA Adversary Proceeding (the CNTA Order) to provide that the Bankruptcy Court shall have entered the CNTA Order by no later than November 23, 2016; (ii) a modification to the deadlines for the Company to file an Acceptable Reorganization Plan (as defined in the DIP Credit Agreement) and related disclosure statement to provide that the Company must file these by, or on, the date that is the later of (a) 30 days after the entry of the CNTA Order and (b) December 14, 2016; and (iii) a modification to the deadline by which the Bankruptcy Court shall enter an order approving the Debtors' disclosure statement to provide that the Bankruptcy Court shall have entered this order by no later than January 31, 2017. The DIP Credit Agreement also contains restrictions on the ability of Peabody Global Funding, LLC (Global Funding) to amend or waive provisions under the Intercompany Loan Agreement (as defined in the DIP Credit Agreement) in a manner that would release or subordinate more than 50% of the collateral thereunder. The DIP Amendment modifies these restrictions to expressly allow Global Funding to amend or waive provisions under the Intercompany Loan Agreement to permit the release or subordination of collateral thereunder, including as a result of potential asset sales, of up to $250 million in cash proceeds in the aggregate over the life of the Intercompany Loan Agreement.

On October 14, 2016, the Debtors filed four omnibus objections to certain proofs of claim.

Additionally, the Bankruptcy Court partially and conditionally granted the motion for relief from the automatic stay filed on September 26, 2016 by the UMWA Plan. The Bankruptcy Court lifted the automatic stay to provide the UMWA Plan until October 28, 2016, to receive a written confirmation from the American Arbitration Association (the AAA) that the AAA could find an arbitrator with sufficient experience who could arbitrate the UMWA Plan's claim and reach a decision, without extension or any exception for cause, by January 26, 2017.

On October 21, 2016, Berenergy Corporation filed a motion to lift the automatic stay to allow it to appeal a final judgment entered in the Sixth Judicial District Court in the state of Wyoming, as discussed in more detail below in Note 19 "Commitments and Contingencies".

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

On October 24, 2016, the Debtors filed a motion to assume or reject non-residential leases to which the Debtors are a party.

On October 25, 2016, the UMWA Plan filed a copy of its correspondence with the AAA and on October 26, 2016, the Bankruptcy Court issued an order lifting the automatic stay to allow arbitration of the claim to proceed. The parties have selected an arbitrator, and the arbitration hearings are scheduled to begin on December 19, 2016.

On October 26, 2016, the Debtors filed a motion to assume certain executory contracts to which certain Debtors are a party, as well as an omnibus motion for the rejection of certain executory contracts regarding overriding royalties.

As a result of the Bankruptcy Petitions, the realization of the Debtors’ assets and the satisfaction of liabilities are subject to significant uncertainty. For the Debtors to emerge successfully from Chapter 11, they must obtain the Bankruptcy Court’s approval of a plan of reorganization, which will enable them to transition from Chapter 11 into ordinary course operations as reorganized entities outside of bankruptcy. A plan of reorganization determines the rights and treatment of claims of various creditors and equity security holders, and is subject to the ultimate outcome of negotiations and Bankruptcy Court decisions ongoing through the date on which the plan of reorganization is confirmed.

The Debtors intend to propose a plan of reorganization on or prior to the applicable date required under the Bankruptcy Code and in accordance with milestones set forth in the DIP Credit Agreement (as set forth below in Note 13. "Current and Long-term Debt"), as the same may be extended with approval of the Bankruptcy Court. As noted above, the Debtors and the parties to the DIP Credit Agreement entered into the DIP Amendment, which modified certain milestone dates. The Debtors presently expect that any proposed plan of reorganization will provide, among other things, for mechanisms for the settlement of claims against the Debtors’ estates, treatment of the Debtors' existing equity and debt holders, and certain corporate governance and administrative matters pertaining to the reorganized Debtors. A proposed plan of reorganization filed with the Bankruptcy Court likely will incorporate provisions arising out of the Debtors' discussions with their creditors and other interested parties, and likely will be further revised thereafter. There can be no assurance that the Debtors will be able to secure approval for their proposed plan of reorganization from the Bankruptcy Court or execute such plan. Further, a plan of reorganization is likely to materially change the amounts and classifications of assets and liabilities reported in the Company’s condensed consolidated financial statements. Although it is uncertain at this stage if any proposed plan of reorganization would allow for distributions with respect to equity or other securities, it is likely that equity securities will be cancelled and extinguished upon confirmation of a proposed plan of reorganization by the Bankruptcy Court, and that the holders thereof would not be entitled to receive, and would not receive or retain, any property or interest in property on account of such equity interests.

The Company believes it will require a significant restructuring of its balance sheet in order to continue as a going concern. The Company’s ability to continue as a going concern is dependent upon, among other things, its ability to become profitable and maintain profitability, its ability to access sufficient liquidity and its ability to successfully implement their Chapter 11 plan of reorganization. The accompanying condensed consolidated financial statements are prepared on a going concern basis and do not include any adjustments that might be required if the Company were unable to continue as a going concern.

(2)    Newly Adopted Accounting Standards and Accounting Standards Not Yet Implemented

Newly Adopted Accounting Standards

Going Concern. In August 2014, the Financial Accounting Standards Board (FASB) issued disclosure guidance that requires management to evaluate, at each annual and interim reporting period, whether substantial doubt exists about an entity's ability to continue as a going concern and, if applicable, to provide related disclosures. As outlined by that guidance, substantial doubt about an entity's ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that an entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued (or are available to be issued). The new guidance is effective for annual reporting periods ending after December 15, 2016 (the year ending December 31, 2016 for the Company) and interim periods thereafter, with early adoption permitted.

Deferred Financing Costs. On April 7, 2015, the FASB issued accounting guidance that requires deferred financing costs to be presented as a direct reduction from the related debt liability in the financial statements rather than as a separately recognized asset. Under the new guidance, amortization of such costs will continue to be reported as interest expense. In August 2015, an update was issued that clarified that debt issuance costs associated with line-of-credit arrangements may continue to be reported as an asset. The new guidance became effective retrospectively for interim and annual periods beginning after December 15, 2015 (January 1, 2016 for the Company). There was no material impact to the Company's results of operations or cash flows in connection with the adoption of the guidance.

The impact to the Company's condensed consolidated balance sheets as of December 31, 2015 was as follows:

	Before Application of Accounting Guidance		Adjustment			After Application of Accounting Guidance
	(Dollars in millions)
Other current assets	$	503.1	$	(55.5	)	$	447.6

Total liabilities	10,102.8		(74.4		)	10,028.4

Accounting Standards Not Yet Implemented

Revenue Recognition. In May 2014, the FASB issued a comprehensive revenue recognition standard that will supersede nearly all existing revenue recognition guidance under U.S. GAAP. The new standard provides a single principles-based, five-step model to be applied to all contracts with customers, which steps are to (1) identify the contract(s) with the customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when each performance obligation is satisfied. More specifically, revenue will be recognized when promised goods or services are transferred to the customer in an amount that reflects the consideration expected in exchange for those goods or services. The standard also requires entities to disclose sufficient qualitative and quantitative information to enable financial statement users to understand the nature, amount, timing and uncertainty of revenues and cash flows arising from contracts with customers.

Under the originally issued standard, the new guidance would have been effective for interim and annual periods beginning after December 15, 2016 (January 1, 2017 for the Company). On July 9, 2015, the FASB decided to delay the effective date of the new revenue recognition standard by one year with early adoption permitted, but not before the original effective date. The standard allows for either a full retrospective adoption or a modified retrospective adoption. The Company is in the process of evaluating the impact that the adoption of this guidance will have on its results of operations, financial condition, cash flows and financial statement presentation.

Inventory. In July 2015, the FASB issued guidance which requires entities to measure most inventory "at the lower of cost and net realizable value", thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market (market in this context is defined as one of three different measures, one of which is net realizable value). The guidance does not apply to inventories that are measured by using either the last-in, first-out method or the retail inventory method. The new guidance will be effective prospectively for annual periods beginning after December 15, 2016 (January 1, 2017 for the Company), and interim periods therein, with early adoption permitted. The Company is in the process of evaluating the impact that the adoption of this guidance will have on its results of operations, financial condition, cash flows and financial statement presentation.

Income Taxes. In November 2015, the FASB issued accounting guidance that requires entities to classify all deferred tax assets and liabilities, along with any related valuation allowance as noncurrent on the balance sheet. Under the new guidance, each jurisdiction will now only have one net noncurrent deferred tax asset or liability. The new guidance does not change the existing requirement that only permits offsetting within a jurisdiction. The new guidance will be effective prospectively or retrospectively for annual periods beginning after December 15, 2016 (January 1, 2017 for the Company) and interim periods therein, with early adoption permitted. While the Company does not anticipate an impact to its results of operations or cash flows in connection with the adoption of this guidance, there will be an impact on the presentation of the Company's condensed consolidated balance sheets. The impact to the condensed consolidated balance sheets will depend upon the facts and circumstances at the time of adoption.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Lease Accounting. In February 2016, the FASB issued accounting guidance that will require a lessee to recognize in its balance sheet a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term for leases with lease terms of more than 12 months.  Consistent with current U.S. GAAP, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. Additional qualitative disclosures along with specific quantitative disclosures will also be required.  The new guidance will take effect for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 (January 1, 2019 for the Company), with early adoption permitted.  Upon adoption, the Company will be required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company is in the process of evaluating the impact that the adoption of this guidance will have on its results of operations, financial condition, cash flows and financial statement presentation. 

Compensation - Stock Compensation. In March 2016, the FASB issued accounting guidance which identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. The new guidance will be effective prospectively for annual periods beginning after December 15, 2016 (January 1, 2017 for the Company) and interim periods therein, with early adoption permitted. The Company is in the process of evaluating the impact that the adoption of this guidance will have on its results of operations, financial condition, cash flows and financial statement presentation.

Financial Instruments - Credit Losses. In June 2016, the FASB issued accounting guidance related to the measurement of credit losses on financial instruments. The pronouncement replaces the incurred loss methodology to record credit losses with a methodology that reflects the expected credit losses for financial assets not accounted for at fair value with gains and losses recognized through net income. This standard is effective for fiscal years beginning after December 15, 2019 (January 1, 2020 for the Company) and interim periods therein,with early adoption permitted for fiscal years, and interim periods therein, beginning after December 15, 2018. The Company is in the process of evaluating the impact that the adoption of this guidance will have on its results of operations, financial condition, cash flows and financial statement presentation.

Classification of Certain Cash Receipts and Cash Payments. In August 2016, the FASB issued accounting guidance to amend the classification of certain cash receipts and cash payments in the statement of cash flows to reduce diversity in practice. The new guidance will be effective for fiscal years beginning after December 15, 2017 (January 1, 2018 for the Company) and interim periods therein, with early adoption permitted. The amendments in this update should be applied retrospectively to all periods presented, unless deemed impracticable, in which case, prospective application is permitted. The Company is currently evaluating this guidance and its impact on classification of certain cash receipts and cash payments in the Company's statements of cash flows.

(3)    Reorganization Items, Net

In accordance with Accounting Standards Codification 852, "Reorganizations," the statement of operations shall portray the results of operations of the reporting entity during the pendency of the Chapter 11 Cases. Revenues, expenses (including professional fees), realized gains and losses, and provisions for losses resulting from reorganization and restructuring of the business shall be reported separately as reorganization items.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

The Company's reorganization items for the three and nine months ended September 30, 2016 consisted of the following:

	Three Months Ended			Nine Months Ended
	September 30, 2016			September 30, 2016
	(Dollars in millions)
Loss on termination of derivative contracts	$	—		$	75.2
Professional fees	31.1			52.7

Interest income	(0.9		)	(1.1		)
Other	—			(1.0		)
Reorganization items, net	$	29.7		$	125.1

As a result of filing the Bankruptcy Petitions, counterparties to certain derivative contracts terminated the agreements shortly thereafter in accordance with their contractual terms and the Company adjusted the corresponding liabilities to be equivalent to the termination value and allowed claim amount, of each contract. Such liabilities are considered first lien debt and are included within "Liabilities subject to compromise" in the accompanying condensed consolidated balance sheet at September 30, 2016.

Professional fees are only those that are directly related to the reorganization including, but not limited to, fees associated with advisors to the Debtors, the Creditors' Committee and certain secured and unsecured creditors.

During the nine months ended September 30, 2016, $30.7 million of cash payments were made for "Reorganization items, net".

(4)    Liabilities Subject to Compromise

Liabilities subject to compromise include unsecured or under-secured liabilities incurred prior to the Petition Date. These liabilities represent the amounts expected to be allowed on known or potential claims to be resolved through the Chapter 11 Cases and remain subject to future adjustments based on negotiated settlements with claimants, actions of the Bankruptcy Court, rejection of executory contracts, proofs of claims or other events. Additionally, liabilities subject to compromise also include certain items that may be assumed under a plan of reorganization, and as such, may be subsequently reclassified to liabilities not subject to compromise. Generally, actions to enforce or otherwise effect payment of prepetition liabilities are subject to the automatic stay, as discussed in Note 1. "Basis of Presentation".

Liabilities subject to compromise consisted of the following:

Previously Reported Balance Sheet Line	September 30, 2016
	(Dollars in millions)
Debt (1)	$	7,920.4
Interest payable	172.6

(5)    Asset Impairment

The Company's mining and exploration assets and mining-related investments may be adversely affected by numerous uncertainties that may cause the Company to be unable to recover all or a portion of the carrying value of those assets. Because of the volatile and cyclical nature of U.S. and international seaborne coal demand, it is reasonably possible that prices may decrease in the near term, which, absent sufficient mitigation such as an offsetting reduction in the Company's operating costs, may result in the need for future adjustments to the carrying value of the Company's long-lived mining assets and mining-related investments.

The Company's assets whose recoverability and values are most sensitive to near-term pricing and other market factors include certain Australian metallurgical and thermal assets for which impairment charges were recorded in 2015 and certain U.S. coal properties being leased to unrelated mining companies under agreements that require royalties to be paid as the coal is mined. These assets had an aggregate carrying value of $577.7 million as of September 30, 2016. The Company conducted a review of those assets for recoverability as of September 30, 2016 and determined that no impairment charge was necessary as of that date.

As further discussed in Note 23. “Subsequent Event”, the Company has entered into an agreement for the sale of its Metropolitan mine. As a result of entering into the transaction, and the approval of the Company’s Board of Directors of such a transaction in October 2016, the Metropolitan mine was deemed to meet held-for-sale accounting criteria in the fourth quarter of 2016. Accordingly, the Company expects to record an after-tax impairment charge of approximately $180 million to write down the assets to their estimated selling price, which is the best estimate of fair value under a held-for-sale accounting model, in the fourth quarter of 2016. The carrying value of the mine is included in the value of assets noted as at-risk in the preceding paragraph.

Three and Nine Months EndedSeptember 30, 2016

The Company reviewed its portfolio of mining tenements and surface lands that were classified as held-for-sale. As a result of that review, the Company recognized an aggregate impairment charge of $17.2 million during the nine months ended September 30, 2016 to write down the carrying value of certain Australian metallurgical assets targeted for divestiture, and eventually divested, to their estimated fair value. For additional information regarding those divested assets, refer to Note 16. "Other Events".

Nine Months Ended September 30, 2015

The following costs are reflected in "Asset impairment" in the unaudited condensed consolidated statement of operations for the nine months ended September 30, 2015:

	Reportable Segment
	Australian Metallurgical Mining		Australian Thermal Mining		Corporate and Other		Consolidated
	(Dollars in millions)
Asset impairment charges:
Long-lived assets	$	527.0	$	8.2	$	182.2	$	717.4
Equity method investments	—		—		183.4		183.4
Total	$	527.0	$	8.2	$	365.6	$	900.8

Australian Metallurgical and Thermal Mining

Due to the severity of the decline in seaborne metallurgical and thermal coal pricing observed during the first half of 2015 and other adverse conditions noted during that period, the Company concluded that indicators of impairment existed surrounding its Australian mining platform as of June 30, 2015. Accordingly, the Company reviewed its Australian mining assets for recoverability and, based on that review, determined that the carrying values of three of its active mines that produce metallurgical coal were not recoverable and recognized an aggregate impairment charge of $230.5 million to write those assets down from their carrying value to their estimated fair value.

PEABODY ENERGY CORPORATION

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Also during the second quarter of 2015, the Company reviewed its portfolio of mining tenements and surface lands to identify non-strategic assets that could be monetized. In connection with that review, certain of such assets were deemed to meet held-for-sale accounting criteria or were otherwise considered more likely to generate cash flows through divestiture rather than development, with the long-term plans for certain adjacent assets also consequently affected. Accordingly, the Company recognized an aggregate impairment charge of $304.7 million to write down those assets from their carrying value to their estimated fair value.

Corporate and Other

Long-lived Assets. In connection with a similar review of the Company's asset portfolio conducted during the second quarter of 2015 to identify non-strategic domestic assets that could be monetized, the Company identified non-strategic, non-coal-supplying assets as held-for-sale rather than held-for-use as of June 30, 2015. Accordingly, the Company recognized an impairment charge of $182.2 million to write the assets down from their carrying value to estimated fair value.

Equity Method Investments. Due to the impairment indicators noted above surrounding the Company's Australian platform, the Company reviewed its total investment in Middlemount Coal Pty Ltd. (Middlemount), which owns the Middlemount Mine in Queensland, Australia, as of June 30, 2015. As a result of that review, the Company determined that the carrying value of its total investment in Middlemount was other-than-temporarily impaired and recorded a charge of $46.6 million to write-off the equity investment and recorded a charge of $136.8 million to write down the carrying value of certain of its loans to Middlemount.

The fair value estimates made during the Company's impairment assessments were determined in accordance with the methods outlined in Note 1. "Summary of Significant Accounting Policies" to the consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015, except in certain instances where indicative bids were received related to non-strategic assets being marketed for divestiture. In those instances, the indicative bids were also considered in estimating fair value.

Risk Management — Non-Coal Trading Activities

The Company is exposed to several risks in the normal course of business, including (1) foreign currency exchange rate risk for non-U.S. dollar expenditures and balances, (2) price risk on coal produced by, and diesel fuel utilized in, the Company's mining operations and (3) interest rate risk that has been partially mitigated by fixed rates on long-term debt. The Company manages a portion of its price risk related to the sale of coal (excluding coal trading activities) using long-term coal supply agreements (those with terms longer than one year), rather than using derivative instruments. Derivative financial instruments have historically been used to manage the Company's risk exposure to foreign currency exchange rate risk, primarily on Australian dollar expenditures made in its Australian mining platform. This risk has historically been managed using forward contracts and options designated as cash flow hedges, with the objective of reducing the variability of cash flows associated with forecasted foreign currency expenditures. The Company has also used derivative instruments to manage its exposure to the variability of diesel fuel prices used in production in the U.S. and Australia with swaps or options, which it has also designated as cash flow hedges, with the objective of reducing the variability of cash flows associated with forecasted diesel fuel purchases. These risk management activities are collectively referred to as "Corporate Hedging" and are actively monitored for compliance with the Company's risk management policies.

During the fourth quarter of 2015, the Company performed an assessment of its risk of nonperformance with respect to derivative financial instruments designated as cash flow hedges in light of three rating agencies downgrading the Company's corporate credit rating during 2015 and declining financial results. The Company determined its hedging relationships were expected to be "highly effective" throughout 2015 based on its quarterly assessments. However, as a result of a deterioration in the Company's credit profile, the Company could no longer conclude, as of December 31, 2015, that its hedging relationships were expected to be "highly effective" at offseting the changes in the anticipated exposure of the hedged item. Therefore, the Company discontinued the application of cash flow hedge accounting subsequent to December 31, 2015 and changes in the fair value of derivative instruments have been recorded as operating costs and expenses in the accompanying unaudited condensed consolidated statements of operations. Previous fair value adjustments recorded in "Accumulated other comprehensive loss" will be frozen until the underlying transactions impact the Company's earnings.

The Company's Bankruptcy Petitions constituted an event of default under the Company's derivative financial instrument contracts and the counterparties terminated the agreements shortly thereafter in accordance with contractual terms. The terminated positions are first-lien obligations under the Company's secured credit agreement dated September 24, 2013 (as amended, the 2013 Credit Facility). The net settlement liability was accounted for as a prepetition liability subject to compromise without credit valuation adjustments. As of September 30, 2016, the Company had no derivative financial instruments in place in relation to diesel fuel or foreign currency exchange rate.

Based on the previous fair value adjustments of the Company's foreign currency hedge contract portfolio recorded in "Accumulated other comprehensive loss", the net loss expected to be reclassified from comprehensive income to earnings over the next 12 months associated with that hedge program is approximately $68 million. Based on the previous fair value adjustments of the Company’s diesel fuel hedge contract portfolio recorded in “Accumulated other comprehensive loss”, the net loss expected to be reclassified from comprehensive income to earnings over the next 12 months associated with that hedge program is approximately $50 million.

Cash Flow Presentation. The Company classifies the cash effects of its Corporate Hedging derivatives within the "Cash Flows From Operating Activities" section of the unaudited condensed consolidated statements of cash flows.

Offsetting and Balance Sheet Presentation

The Company's Corporate Hedging derivative financial instruments were transacted in over-the-counter (OTC) markets with financial institutions under International Swaps and Derivatives Association (ISDA) Master Agreements. Those agreements contain symmetrical default provisions which allow for the net settlement of amounts owed by either counterparty in the event of default or contract termination. The Company offsets its Corporate Hedging asset and liability derivative positions on a counterparty-by-counterparty basis in the condensed consolidated balance sheets, with the fair values of those respective derivatives reflected in “Other current assets,” “Investments and other assets,” “Accounts payable and accrued expenses” and “Other noncurrent liabilities." Though the symmetrical default provisions associated with the Company's Corporate Hedging derivatives exist at the overall counterparty level across its foreign currency and diesel fuel hedging strategy derivative contract portfolios, the Company's accounting policy is to apply counterparty offsetting separately within those derivative contract portfolios for presentation in the condensed consolidated balance sheets because that application is more consistent with the fact that the Company generally net settles its Corporate Hedging derivatives with each counterparty by derivative contract portfolio on a routine basis.

The classification and amount of Corporate Hedging derivative financial instruments presented on a gross and net basis as of December 31, 2015 are presented in the table that follows.

Financial Instrument	Fair Value of Liabilities Presented in the Condensed Consolidated Balance Sheet as of December 31, 2015 (1)
	(Dollars in millions)
Current Liabilities:
Commodity swap contracts	$	86.1
Foreign currency forward contracts	145.6
Total	$	231.7
Noncurrent Liabilities:

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.

Financial Instruments Measured on a Recurring Basis. The following tables set forth the hierarchy of the Company’s net financial liability positions for which fair value is measured on a recurring basis:

	December 31, 2015
	Level 1		Level 2		Level 3			Total
	(Dollars in millions)
Commodity swap contracts	—		—		(123.7		)	(123.7		)
Foreign currency contracts	—		—		(200.7		)	(200.7		)
Total net financial liabilities	$	—	$	—	$	(324.4	)	$	(324.4	)

As of September 30, 2016, the Company no longer had any outstanding financial positions.

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:

• Commodity swap contracts — diesel fuel and explosives: valued based on 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, then the Company classifies such contracts as Level 3.

• Foreign currency forward and option contracts: 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.

The following table summarizes the changes related to the Company’s Corporate Hedging derivative financial instruments recurring Level 3 financial liabilities:

	Nine Months Ended
	September 30, 2016
	Commodity Contracts			Foreign Currency Contracts			Total
	(Dollars in millions)

Settlements / terminations	(139.4		)	(152.7		)	(292.1		)
End of period	$	—		$	—		$	—

⁽¹⁾ Includes reorganization items and realized gains (losses)

The Company had no transfers between Levels 1, 2 and 3 during the three and nine months ended September 30, 2016 or 2015. Transfers into Level 3 of liabilities previously classified in Level 2 during the year ended December 31, 2015 were due to the relative value of unobservable inputs to the total fair value measurement of certain derivative contracts rising above the 10% threshold. The Company’s policy is to value all transfers between levels using the beginning of period valuation.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Other Financial Instruments. The Company used the following methods and assumptions in estimating fair values for other financial instruments as of September 30, 2016 and December 31, 2015:

• 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 with an active trading market when available (Level 2), and otherwise on estimated borrowing rates to discount the cash flows to their present value (Level 3).

The estimated fair value of the Company’s current and long-term debt as of September 30, 2016 is subject to compromise in connection with the Company's plan of reorganization and as such has been excluded from the table below. The carrying amount and estimated fair value of the Company's current and long-term debt as of December 31, 2015 are summarized as follows:

	December 31, 2015
	Carrying Amount		Estimated Fair Value
	(Dollars in millions)
Current and Long-term debt	$	6,241.2	$	1,372.7

(9)     Coal Trading

The Company engages in the direct and brokered trading of coal and freight-related contracts (coal trading). Except those 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.

The Company includes instruments associated with coal trading transactions as a part of its trading book. Trading revenues from such transactions are recorded in “Other revenues” in the unaudited condensed consolidated statements of operations and include realized and unrealized gains and losses on derivative instruments, including those that arise from coal deliveries related to contracts accounted for on an accrual basis under the normal purchases and normal sales exception. Therefore, the Company has elected the trading exemption surrounding disclosure of its coal trading activities.

Trading (losses) revenues recognized during the three and nine months ended September 30, 2016 and 2015 were as follows:

	Three Months Ended						Nine Months Ended
	September 30,						September 30,
Trading Revenues by Type of Instrument	2016			2015			2016			2015
	(Dollars in millions)
Futures, swaps and options	$	(32.4	)	$	47.7		$	(68.7	)	$	89.4
Physical purchase/sale contracts	13.2			(23.2		)	36.1			(46.7		)
Total trading (losses) revenues	$	(19.2	)	$	24.5		$	(32.6	)	$	42.7

Risk Management

Hedge Ineffectiveness. In some instances, the Company has designated an existing coal trading derivative as a hedge and, thus, the derivative has a non-zero fair value at hedge inception. The “off-market” nature of these derivatives, which is best described as an embedded financing element within the derivative, is a source of ineffectiveness. In other instances, the Company uses a coal trading derivative that settles at a different time, has different quality specifications or has a different location basis than the occurrence of the cash flow being hedged. These collectively yield ineffectiveness to the extent that the derivative hedge contract does not exactly offset changes in the fair value or expected cash flows of the hedged item.

The Company had no coal trading positions designated as cash flow hedges as of September 30, 2016 and December 31, 2015.

Offsetting and Balance Sheet Presentation

The Company's coal trading assets and liabilities include financial instruments, such as swaps, futures and options, cleared through various exchanges, which involve the daily net settlement of closed positions. The Company must post cash collateral, known as variation margin, on exchange-cleared positions that are in a net liability position and receives variation margin when in a net asset position. The Company also transacts in coal trading financial swaps and options through OTC markets with financial institutions and other non-financial trading entities under ISDA Master Agreements, which contain symmetrical default provisions. Certain of the Company's coal trading agreements with OTC counterparties also contain credit support provisions that may periodically require the Company to post, or entitle the Company to receive, initial and variation margin. Physical coal and freight-related purchase and sale contracts included in the Company's coal trading assets and liabilities are executed pursuant to master purchase and sale agreements that also contain symmetrical default provisions and allow for the netting and setoff of receivables and payables that arise during the same time period. The Company offsets its coal trading asset and liability derivative positions, and variation margin related to those positions, on a counterparty-by-counterparty basis in the condensed consolidated balance sheets, with the fair values of those respective derivatives reflected in “Assets from coal trading activities, net” and “Liabilities from coal trading activities, net."

The fair value of assets and liabilities from coal trading activities presented on a gross and net basis as of September 30, 2016 and December 31, 2015 is set forth below:

Total net financial assets (liabilities)	$	—	$	23.5	$	(15.6	)	$	7.9

For Level 1 and 2 financial assets and liabilities, the Company utilizes both direct and indirect observable price quotes, including U.S. interest rate curves; LIBOR yield curves; Chicago Mercantile Exchange (CME) Group, Intercontinental Exchange (ICE), LCH.Clearnet (formerly known as the London Clearing House), NOS Clearing ASA and Singapore Exchange (SGX) contract prices; broker quotes; published indices and other market quotes. Below is a summary of the Company’s valuation techniques for Level 1 and 2 financial assets and liabilities:

• Futures, swaps and options: 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.

• Physical purchase/sale contracts: purchases and sales at locations with significant market activity corroborated by market-based information (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.

Physical purchase/sale contracts include a credit valuation adjustment based on credit and non-performance risk (Level 3). The credit valuation adjustment has not historically had a material impact on the valuation of the contracts resulting in Level 2 classification. However, due to the Company's corporate credit rating downgrades in 2015, the credit valuation adjustments as of September 30, 2016 and December 31, 2015 are considered to be significant unobservable inputs in the valuation of the contracts resulting in Level 3 classification.

The Company's risk management function, which is independent of the Company's commercial trading function, is responsible for valuation policies and procedures, with oversight from executive management. Generally, the Company's Level 3 instruments or contracts are valued using bid/ask price quotations and other market assessments obtained from multiple, independent third-party brokers or other transactional data incorporated into internally-generated discounted cash flow models. Decreases in the number of third-party brokers or market liquidity could erode the quality of market information and therefore the valuation of the Company's market positions. The Company's valuation techniques include basis adjustments to the foregoing price inputs for quality, such as heat rate and sulfur and ash content, location differentials, expressed as port and freight costs, and credit risk. The Company's risk management function independently validates the Company's valuation inputs, including unobservable inputs, with third-party information and settlement prices from other sources where available. A daily process is performed to analyze market price changes and changes to the portfolio. Further periodic validation occurs at the time contracts are settled with the counterparty. These valuation techniques have been consistently applied in all periods presented, and the Company believes it has obtained the most accurate information available for the types of derivative contracts held.

The following table summarizes the quantitative unobservable inputs utilized in the Company's internally-developed valuation models for physical commodity purchase/sale contracts classified as Level 3 as of September 30, 2016:

	Range				Weighted
Input	Low		High		Average
Quality adjustments	2	%	2	%	2	%
Location differentials	9	%	9	%	9	%
Credit and non-performance risk	26	%	26	%	26	%

Significant increases or decreases in the inputs in isolation could result in a significantly higher or lower fair value measurement. The unobservable inputs do not have a direct interrelationship; therefore, a change in one unobservable input would not necessarily correspond with a change in another unobservable input.

The following table summarizes the changes in the Company’s recurring Level 3 net financial assets:

The Company had no transfers between Levels 1 and 2 during the three and nine months ended September 30, 2016 and 2015. Transfers of liabilities into/out of Level 3 from/to Level 2 during the three and nine months ended September 30, 2016 were due to the relative value of unobservable inputs to the total fair value measurement of certain derivative contracts falling below, or in the case of transfers in rising above, the 10% threshold. The Company’s policy is to value all transfers between levels using the beginning of period valuation.

As of September 30, 2016, the timing of the estimated future realization of the value of the Company’s trading portfolio, on a cumulative cash basis, was as follows:

2017	(171	)%

Credit and Non-performance Risk. 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’s policy is to independently evaluate each customer’s creditworthiness prior to entering into transactions and to regularly monitor the credit extended. If the Company engages in a transaction with a counterparty that does not meet its credit standards, the Company seeks to protect its position by requiring the counterparty to provide an appropriate credit enhancement. Also, when appropriate (as determined by its credit management function), the Company has taken steps to reduce its exposure to customers or counterparties whose credit has deteriorated and who may pose a higher risk of failure to perform under their contractual obligations. These steps include obtaining letters of credit or cash collateral (margin), requiring prepayments for shipments or the creation of customer trust accounts held for the Company’s benefit to serve as collateral in the event of a failure to pay or perform. To reduce its credit exposure related to trading and brokerage activities, the Company seeks to enter into netting agreements with counterparties that permit the Company to offset asset and liability positions with such counterparties and, to the extent required, the Company will post or receive margin amounts associated with exchange-cleared and certain OTC positions. The Company also continually monitors counterparty and contract non-performance risk, if present, on a case-by-case basis.

At September 30, 2016, 65% of the Company’s credit exposure related to coal trading activities with investment grade counterparties, while 11% was with non-investment grade counterparties and 24% was with counterparties that are not rated.

Performance Assurances and Collateral

Certain of the Company’s derivative trading instruments require the parties to provide additional performance assurances whenever a material adverse event jeopardizes one party’s ability to perform under the instrument. If the Company was to sustain a material adverse event (using commercially reasonable standards), its counterparties could request collateralization on derivative trading instruments in net liability positions which, based on an aggregate fair value at September 30, 2016 and December 31, 2015, would have amounted to collateral postings to counterparties of approximately $1 million and $21 million, respectively. As of September 30, 2016, the Company was required to post approximately $4 million in collateral to counterparties for such positions. No collateral was required to be posted to counterparties as of December 31, 2015.

Certain of the Company’s other derivative trading instruments require the parties to provide additional performance assurances whenever a credit downgrade occurs below a certain level, as specified in each underlying contract. The terms of such derivative trading instruments typically require additional collateralization, which is commensurate with the severity of the credit downgrade. During the second quarter of 2016, each of the three rating agencies downgraded the Company's corporate credit rating due to the Bankruptcy Petitions. Despite the rating agencies downgrades, the Company’s additional collateral requirement owed to its counterparties for these ratings based derivative trading instruments would have been zero at September 30, 2016 and December 31, 2015 based on the aggregate fair value of all derivative trading instruments with such features. As of September 30, 2016 and December 31, 2015, no collateral was posted to counterparties to support such derivative trading instruments.

The Company is required to post variation margin on positions that are in a net liability position and is entitled to receive and hold variation margin on positions that are in a net asset position with an exchange and certain of its OTC derivative contract counterparties. At September 30, 2016 and December 31, 2015, the Company posted a net variation margin of $57.9 million and held a net variation margin of $10.7 million, respectively.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

In addition to the requirements surrounding variation margin, the Company is required by the exchanges upon which it transacts and by certain of its OTC arrangements to post certain additional collateral, known as initial margin, which represents an estimate of potential future adverse price movements across the Company’s portfolio under normal market conditions. As of September 30, 2016 and December 31, 2015, the Company had posted initial margin of $11.3 million and $9.2 million, respectively, which is reflected in “Other current assets” in the condensed consolidated balance sheets. As of September 30, 2016 and December 31, 2015, the Company was in receipt of $1.3 million and $0.7 million of margin in excess of the required variation and initial margin.

(10) Financing Receivables

The Company's total financing receivables as of September 30, 2016 and December 31, 2015 consisted of the following:

Balance Sheet Classification	September 30, 2016		December 31, 2015
	(Dollars in millions)
Other current assets	$	—	$	20.0
Investments and other assets	68.6		65.2
Total financing receivables	$	68.6	$	85.2

The Company periodically assesses the collectability of accounts and loans receivable by considering factors such as specific evaluation of collectability, historical collection experience, the age of the receivable and other available evidence. Below is a description of the Company's financing receivables outstanding as of September 30, 2016.

Codrilla Mine Project. In 2011, a wholly-owned subsidiary of PEA-PCI, then Macarthur Coal Limited, completed the sale of a portion of its 85% interest in the Codrilla Mine Project to the other participants of the Coppabella Moorvale Joint Venture, afterward retaining 73.3% ownership.The final outstanding installment payment of 40% of the sale price was due upon the earlier of the mine's first coal shipment or a specified date. The sales agreement was amended in the second quarter of 2013 to delay the specified date from March 31, 2015 to June 30, 2016. The remaining balance was received during the nine months ended September 30, 2016. At December 31, 2015, the balance associated with these receivables totaled $20.0 million and was recorded in "Other current assets" in the condensed consolidated balance sheets.

Middlemount. The Company periodically makes loans (Priority Loans) to Middlemount, in which the Company owns a 50% equity interest, pursuant to the related shareholders’ agreement for purposes of funding capital expenditures and working capital requirements. The Priority Loans bear interest at a rate equal to the monthly average 30-day Australian Bank Bill Swap Reference Rate plus 3.5% and expire on December 31, 2016. Based on the existence of letters of support from related entities of the shareholders, the expected timing of repayment of these loans is projected to extend beyond the stated expiration date and so the Company considers these loans to be of a long-term nature. As a result, (i) the foreign currency impact related to the shareholder loans is included in foreign currency translation adjustment in the condensed consolidated balance sheets and the unaudited condensed consolidated statements of comprehensive income and (ii) interest income on the Priority Loans is recognized when cash is received. Refer to Note 2. "Asset Impairment" to the consolidated financial statements included in the Company's Annual Report on form 10-K for the year ended December 31, 2015 for background surrounding the impairment charge recognized in 2015 related to Middlemount. The carrying value of the loans of $58.3 million and $65.2 million was reflected in "Investments and other assets" in the condensed consolidated balance sheets as of September 30, 2016 and December 31, 2015, respectively.

On August 8, 2016, one of the Company's Australian subsidiaries and the other shareholder of Middlemount entered into an agreement to provide a revolving loan (Revolving Loans) to Middlemount not to exceed $60.0 million Australian dollars (Revolving Loan Limit). The Company’s participation in the Revolving Loans will not, at any time, exceed its 50% equity interest of the Revolving Loan Limit. The Revolving Loans bear interest at 15% per annum and expire on December 31, 2017. As of September 30, 2016, the carrying value of the Revolving Loans due to the Company's Australian subsidiary was $10.3 million.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

The Company's consolidated financial statements as of December 31, 2015 were prepared under a going concern opinion, and as such, all of its long-term debt with the exception of the Debentures was classified as current. As of September 30, 2016, all of the Company's long-term debt with the exception of the DIP Term Loan Facility (as defined below) and certain other debt arrangements was recorded in “Liabilities subject to compromise” in the condensed consolidated balance sheets. The DIP Term Loan Facility (as defined below) and certain other debt arrangements were recorded in “Current portion of long-term debt” in the condensed consolidated balance sheets as of September 30, 2016.

During the first quarter of 2016, the Company borrowed $947.0 million under the $1.65 billion revolving credit facility (as amended, the 2013 Revolver) for general corporate purposes. As of the Petition Date, the Company had approximately $675 million letters of credit outstanding on the 2013 Revolver.  Subsequent to the Petition Date, certain counterparties drew on a portion of those letters of credit.  The letters of credit were in place to support various types of obligations, though the most significant items related to bank guarantees in place for certain reclamation obligations in Australia.  The draws required the recording of previously off-balance sheet liabilities, except in certain instances where the Company had previously recorded a liability, and as such have been reflected as additional borrowings under the 2013 Revolver.  The total of such letters of credit was $441.4 million as of September 30, 2016. "Investments and other assets" in the condensed consolidated balance sheets as of September 30, 2016 includes $343.7 million of collateral in support of certain of these obligations.

As a result of filing the Bankruptcy Petitions on April 13, 2016, as discussed in Note 1. "Basis of Presentation", the Company is in default under the 2013 Credit Facility and as such the 2013 Revolver can no longer be utilized.

Additional information regarding the Company's current and long-term debt is outlined in Note 12 to the consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2015.

The filing of the Bankruptcy Petitions constituted an event of default that accelerated Peabody’s obligations under the following debt instruments (collectively, the “Debt Instruments”):

• Indenture governing $1,000.0 million outstanding aggregate principal amount of the Company’s 10.00% Senior Secured Second Lien Notes due 2022, dated as of March 16, 2015, among the Company, U.S. Bank National Association (“U.S. Bank”), as trustee and collateral agent, and the guarantors named therein;

• Subordinated Indenture governing $732.5 million outstanding aggregate principal amount of the Company’s Convertible Junior Subordinated Debentures due 2066, dated as of December 20, 2006, among the Company and U.S. Bank, as supplemented; and

• Amended and Restated Credit Agreement, as amended and restated as of September 24, 2013 (the 2013 Credit Facility), related to $1,170.0 million outstanding aggregate principal amount of term loans under the 2013 Term Loan Facility and $1,650.0 million in the 2013 Revolver which includes approximately $675 million of posted but undrawn letters of credit and approximately $947 million in outstanding borrowings, by and among the Company, Citibank, N.A., as administrative agent, swing line lender and letter of credit (L/C) issuer, Citigroup Global Markets, Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, BNP Paribas Securities Corp., Crédit Agricole Corporate and Investment Bank, HSBC Securities (USA) Inc., Morgan Stanley Senior Funding, Inc., PNC Capital Markets LLC and RBS Securities Inc., as joint lead arrangers and joint book managers, and the lender parties thereto, as amended by that certain Omnibus Credit Agreement, dated as of February 5, 2015.

Intercompany Loan Agreement

Prior to the Petition Date, the Company made available to its Australian platform a committed $250 million revolving intercompany loan facility (Intercompany Loan Agreement). The Intercompany Loan Agreement is designed to provide liquidity to support the ongoing operations of the Australian business during the Chapter 11 Cases, with draw amounts being tied to operating budgets and subject to certain availability restrictions. In accordance with the terms of the DIP Credit Agreement, the aggregate outstanding principal amount shall not exceed $250 million at any one time, which amount shall be subject to increase by up to $200 million with the written consent of the DIP Lenders. The consent of the DIP Lenders is also required to grant liens valued at 50% or more of the assets collateralizing the Intercompany Loan Agreement; however, as discussed in Note 1. "Basis of Presentation", the DIP Lenders have expressly consented to an amendment or waiver of provisions in the Intercompany Loan Agreement to permit the release or subordination of collateral thereunder, including as a result of potential asset sales, of up to $250 million in cash proceeds in the aggregate over the life of the Intercompany Loan Agreement and the agreement was amended accordingly. As of September 30, 2016, $30.0 million was outstanding on the Intercompany Loan Agreement.

Senior Secured Second Lien Notes Offering

On March 16, 2015, the Company completed the offering of $1.0 billion aggregate principal amount of the Senior Secured Second Lien Notes.

Annual contributions to the qualified plans are made in accordance with minimum funding standards and the Company's agreement with the Pension Benefit Guaranty Corporation (PBGC). Funding decisions also consider certain funded status thresholds defined by the Pension Protection Act of 2006 (generally 80%). As of September 30, 2016, the Company's qualified plans were expected to be at or above the Pension Protection Act thresholds and therefore are expected to avoid benefit restrictions and at-risk penalties for 2016. During the three and nine months ended September 30, 2016, the Company contributed $0.4 million and $0.5 million respectively, to its qualified pension plans. During the nine months ended September 30, 2016, the Company contributed $0.6 million to its non-qualified pension plans. On November 2, 2015, the Bipartisan Budget Act of 2015 (BBA15) was signed into law, which extends pension funding stabilization provisions that were part of the Highway and Transportation Funding Act of 2014 (HATFA) and the Moving Ahead for Progress in the 21st Century Act of 2012 (MAP-21). Under BBA15, the pension funding stabilization provisions temporarily increased the interest rates used to determine pension liabilities for purposes of minimum funding requirements through 2020. Similar to MAP-21, BBA15 is not expected to change the Company's total required cash contributions over the long term, but is expected to reduce the Company's required cash contributions through 2020 if current interest rate levels persist. Based upon minimum funding requirements in accordance with HATFA and BBA15, the Company expects to contribute approximately $0.5 million to its pension plans to meet minimum funding requirements for its qualified plans in 2016. Contributions to non-qualified pension plans ceased subsequent to April 12, 2016 as a result of filing the Bankruptcy Petitions.

(16) Other Events

Organizational Realignment

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 global coal industry conditions. Costs associated with restructuring actions can include 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.

In 2016, the Company has continued to drive operational efficiencies, optimize production across its mining platform and control operational and administrative expenses. Included in the Company's unaudited condensed consolidated statements of operations were aggregate restructuring charges, primarily comprised of cash severance costs, of $0.3 million and $1.8 million for the three months ended September 30, 2016 and 2015, respectively, and $15.5 million and $23.0 million, for the nine months ended September 30, 2016 and 2015, respectively.

Restricted Cash

As of September 30, 2016, the Company had restricted cash representing collateral for financial assurances associated with reclamation and other obligations of $70.6 million and $1.4 million included in “Investments and other assets” and "Restricted cash", respectively.  Refer to Note 18. "Financial Instruments and Other Guarantees" for details regarding the remaining $22.8 million in restricted cash.

Take-or-pay Obligations

During the nine months ended September 30, 2016, the Company amended contracts to reduce certain U.S. transportation and logistics costs. In connection with these amendments, the Company will realize a net reduction of approximately $45 million in estimated liquidated damage payments that otherwise would have become due with respect to these take-or-pay obligations in 2017. In connection with these amendments, the Company paid liquidated damages of $15.5 million during the nine months ended September 30, 2016.

Divestitures

In May 2016, the Company completed the sale of its 5.06% participation interest in the Prairie State Energy Campus to the Wabash Valley Power Association for $57.1 million. The Company recognized a gain on sale of $6.2 million related to the transaction, which was classified in "Net gain on disposal of assets" in the unaudited condensed consolidated statement of operations for the nine months ended September 30, 2016.

In May 2016, the Company entered into sale and purchase agreements with Australia-based Pembroke Resources to sell its interest in undeveloped metallurgical reserve tenements in Queensland's Bowen Basin for $64.1 million in cash plus a royalty stream. The transaction included Olive Downs South, Olive Downs South Extended and Willunga tenements. The Company recognized a gain on sale of $2.8 million related to the transaction, which was classified in "Net gain on disposal of assets" in the unaudited condensed consolidated statement of operations for the nine months ended September 30, 2016.

In November 2015, the Company entered into a definitive agreement to sell its New Mexico and Colorado assets to a subsidiary of Bowie Resource Partners, LLC (Bowie) in exchange for cash proceeds of $358 million and the assumption of certain liabilities. Bowie agreed to pay the Company $20 million if it failed to obtain financing within the time frame allotted under the agreement (Termination Fee). Bowie did not obtain the necessary financing within the time allowed under the agreement, nor the additional time Peabody agreed to provide at Bowie's request. On April 12, 2016, Peabody then requested that the Termination Fee be paid, which Bowie has not done. The Company has brought action against Bowie to recover the Termination Fee, interest and certain costs.

Customer Contract Amendment

During the second quarter of 2016, the Company amended its arrangements concerning its long-term supply contract with the largest customer of its Australian Thermal Mining segment as a result of the Debtors' Bankruptcy Petitions. Coal under the supply contract is sourced from the Company's Wilpinjong Mine. The Bankruptcy Petitions enabled the customer to exercise their contractual step-in rights to appoint a receiver to operate the mine within the parameters of the agreement; however, the customer has not exercised this right. Under the new arrangements, the Company's subsidiary agreed to post cash collateral of $50.0 million Australian dollars by September 15, 2016, all of which was posted as of September 30, 2016 and is included in "Investments and other assets" in the condensed consolidated balance sheet. The subsidiary also agreed to maintain compliance with additional covenants and restrictions, including achieving minimum quarterly cash flow and production volumes in relation to specific forecasted amounts. If these conditions are met, the customer will not exercise their step-in rights to appoint a receiver. The arrangements provide for remedial action where certain covenants are not met; but noncompliance could result in termination of the amended arrangements and enable the customer to exercise step-in rights to appoint a receiver to operate the Wilpinjong Mine. As of November 2, 2016, the Company was in compliance with the covenants and restrictions under the new arrangements.

Impact of the Chapter 11 Cases on Certain Leases

The Company leases equipment and facilities under various noncancelable lease agreements. Certain lease agreements were subject to the restrictive covenants of the 2013 Credit Facility and include cross-acceleration provisions, under which the lessor could require certain remedies including, but not limited to, immediate recovery of the present value of any remaining lease payments. In relation to the Company's non-debtor subsidiaries, the Company is in various stages of negotiating stand-still arrangements with some lessors where the lessor will not exercise those rights. The Company does not currently believe it is probable the lessors will exercise those rights for the non-debtor subsidiaries. The lessors' rights related to the Debtor subsidiaries were automatically stayed as a result of the filing of the Chapter 11 Cases. As of September 30, 2016, the Company had approximately $215 million of remaining commitments under these non-debtor lease arrangements.

(17) Earnings per Share (EPS)

Basic and diluted EPS are computed using the two-class method, which is an earnings allocation that determines EPS for each class of common stock and participating securities according to dividends declared and participation rights in undistributed earnings. The Company’s restricted stock awards are considered participating securities because holders are entitled to receive non-forfeitable dividends during the vesting term. Diluted EPS includes securities that could potentially dilute basic EPS during a reporting period, for which the Company includes the Debentures and share-based compensation awards. 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 the performance units, which are further described in Note 18. "Share-Based Compensation" in the Company's Annual Report on Form 10-K for the year ended December 31, 2015, 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 the Company’s 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. For further discussion of the Company’s share-based compensation awards, see Note 18. "Share-Based Compensation" to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015.

A conversion of the Debentures may result in payment for any conversion value in excess of the principal amount of the Debentures in the Company’s common stock. For diluted EPS purposes, potential common stock is calculated based on whether the market price of the Company’s common stock at the end of each reporting period is in excess of the conversion price of the Debentures. For a full discussion of the conditions under which the Debentures may be converted, the conversion rate to common stock and the conversion price, see Note 12. "Long-term Debt" to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. The effect of the Debentures was excluded from the calculation of diluted EPS for all periods presented herein because to do so would have been anti-dilutive for those periods.

PEABODY ENERGY CORPORATION

(DEBTOR-IN-POSSESSION)

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

The computation of diluted EPS also excluded aggregate share-based compensation awards of approximately 0.4 million and 0.3 million for the three months ended September 30, 2016 and 2015, respectively, and 0.4 million and 0.3 million for the nine months ended September 30, 2016 and 2015, 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.

The following illustrates the earnings allocation method utilized in the calculation of basic and diluted EPS. The number of shares and per share amounts for all periods presented below have been retroactively restated to reflect the Reverse Stock Split discussed in Note 1. "Basis of Presentation."

The Company owns a 37.5% interest in Dominion Terminal Associates, a partnership that operates a coal export terminal in Newport News, Virginia under a 30-year lease that permits the partnership to purchase the terminal at the end of the lease term for a nominal amount. The partners have severally (but not jointly) agreed to make payments under various agreements which, in the aggregate, provide the partnership with sufficient funds to pay rents and to cover the principal and interest payments on the floating-rate industrial revenue bonds issued by the Peninsula Ports Authority, and which are supported by letters of credit from a commercial bank. On July 1, 2016, $39.9 million of the total $42.7 million of letters of credit supporting the reimbursement obligation to the commercial bank were drawn down to repay the outstanding bonds. As a result, the bonds were retired with the balance of the letters of credit canceled.

The Company is party to an agreement with the PBGC and TXU Europe Limited, an affiliate of the Company’s former parent corporation, under which the Company is required to make contributions to two of the Company’s qualified defined benefit pension plans and to maintain a $37.0 million letter of credit in favor of the PBGC. If the Company or the PBGC gives notice of an intent to terminate one or more of the covered pension plans in which liabilities are not fully funded, or if the Company fails to maintain the letter of credit, the PBGC may draw down on the letter of credit and use the proceeds to satisfy liabilities under the Employee Retirement Income Security Act of 1974, as amended. The PBGC, however, is required to first apply amounts received from a $110.0 million guarantee in place from TXU Europe Limited in favor of the PBGC before it draws on the Company’s letter of credit. On November 19, 2002, TXU Europe Limited was placed under the administration process in the U.K. (similar to a bankruptcy process) and continues under this process as of September 30, 2016. As a result of these proceedings, TXU Europe Limited may be liquidated or otherwise reorganized in such a way as to relieve it of its obligations under its guarantee.

Self-Bonding

During August and September 2016, the Bankruptcy Court approved four motions for Stipulations and Orders (collectively, the “Stipulations”) regarding settlement agreements with the states of Wyoming, New Mexico, Indiana, and Illinois. The Stipulations provide the relevant state authorities with additional financial assurance for the Company’s performance of its reclamation obligations by entitling them to (i) claims in the Chapter 11 Cases that have priority over all administrative expenses of the kind specified in section 503(b) of the Bankruptcy Code for the specified values set forth in the Stipulations and (ii) in the cases of Wyoming, Indiana and Illinois, $0.8 million, $7.5 million and $3.2 million, respectively, in letters of credit or surety bonds related to closed mining operations, together not to exceed the full amount of the $200 million bonding accommodation facility provided for in the DIP Credit Agreement. Each state received financial assurances equal to approximately 17.5% of the Company's prepetition reclamation bond amount with the relevant state. In addition to providing supplemental financial assurances to these states, the Company has agreed to, among other things, quarterly reclamation activity status meetings as well as targeting reductions in the amount of bonds outstanding with these states. Pursuant to the Stipulations, the states will effectively deem the Company’s bonding requirements satisfied for the pendency of the Chapter 11 Cases.

As previously disclosed, the Company's ability to self-bond reduces the Company's costs of securing reclamation obligations and enhances liquidity to the extent alternate forms of bonding would require the Company to post collateral. To the extent the Company is unable to maintain its current level of self-bonding following the conclusion of the Chapter 11 Cases for any reason, the Company would be required to obtain replacement financial assurances or security. Further, self-bonding is permitted at the discretion of each state. As of September 30, 2016, the Company was self-bonded in Illinois, Indiana, New Mexico and Wyoming. The Company is in discussions with Illinois, Indiana, New Mexico and Wyoming regarding the Company’s reclamation bonding over the long term.

Accounts Receivable Securitization

On March 25, 2016, the Company amended and restated its accounts receivable securitization program (securitization program) to, among other things, extend the term of the program by two years to March 23, 2018 and reduce the maximum availability under the facility from $275.0 million to $180.0 million. The accessible capacity of the program varies daily, dependent upon the actual amount of receivables available for contribution and various reserves and limits. As of September 30, 2016, $22.8 million was deposited in a collateral account to secure obligations under the facility.

Under the securitization program, the Company contributes the trade receivables of most of its U.S. subsidiaries on a revolving basis to its wholly-owned, bankruptcy-remote subsidiary (Seller), which then sells the receivables in their entirety to unaffiliated asset-backed commercial paper conduits and banks (the Conduits). After the sale, the Company, as servicer of the assets, collects the receivables on behalf of the Conduits for a nominal servicing fee.

The Seller is a separate legal entity whose assets are available first and foremost to satisfy the claims of its creditors. Of the receivables sold to the Conduits, a portion of the amount due to the Seller is deferred until the ultimate collection of the underlying receivables. During the nine months ended September 30, 2016, the Company received total consideration of $2,109.6 million related to accounts receivable sold under the securitization program, including $1,102.6 million of cash up front from the sale of the receivables, an additional $836.4 million of cash upon the collection of the underlying receivables and $170.6 million that had not been collected at September 30, 2016 and was recorded at carrying value, which approximates fair value. The reduction in accounts receivable as a result of securitization activity with the Conduits was zero and $168.5 million at September 30, 2016 and December 31, 2015, respectively. As of September 30, 2016, $144.9 million in letters of credit remained outstanding under the securitization program.

The securitization activity has been reflected in the unaudited condensed consolidated statements of cash flows as an operating activity because both the cash received from the Conduits upon sale of the receivables as well as the cash received from the Conduits upon the ultimate collection of the receivables are not subject to significantly different risks given the short-term nature of the Company’s trade receivables. The Company recorded expense associated with securitization transactions of $2.4 million and $0.5 million for the three months ended September 30, 2016 and 2015, and $5.6 million and $1.3 million for the nine months ended September 30, 2016 and 2015, respectively.

During the second quarter of 2016, the Company executed two additional amendments to the March 25, 2016 agreement. These amendments permit the continuation of the securitization program through the Company’s Chapter 11 Cases. On April 12, 2016, the Company entered into an amendment to its securitization program to state that the filing of the Bankruptcy Petitions would not result in an automatic termination of the securitization program that would result in the acceleration of the obligations thereunder. On the Petition Date, the Debtors filed a motion seeking Bankruptcy Court approval of the continuation of the securitization program on the terms set forth in the amendments. On April 15, 2016, the Bankruptcy Court entered an order approving this motion on an interim basis. On April 18, 2016, the Company entered into an additional amendment to its securitization program to (i) change the maturity date to the earlier of March 23, 2018 and the emergence of the Company from the Chapter 11 Cases, (ii) revise the schedule of fees and (iii) enter into an additional performance guarantee by the Company’s subsidiaries that are contributors under the securitization facility promising to fulfill obligations of the other contributors. On May 17, 2016, the Bankruptcy Court approved the securitization program on a final basis and entered an order to that effect on May 18, 2016.

Other

Included in "Liabilities subject to compromise" and "Other noncurrent liabilities", respectively, in the Company's condensed consolidated balance sheets as of September 30, 2016 and December 31, 2015 is a liability of $38.4 million related to certain commitments provided on behalf of a third-party coal producer associated with a 2007 purchase of coal reserves and surface lands in the Illinois Basin.

The Company is the lessee under numerous equipment and property leases. It is common in such commercial lease transactions for the Company, as the lessee, to agree to indemnify the lessor 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, would be covered by insurance (subject to deductibles). The Company and certain of its subsidiaries have guaranteed other subsidiaries’ performance under various lease obligations. 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.

There were no other material changes to the Company’s commitments from the information provided in Note 24 to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015.

Contingencies

From time to time, the Company or its subsidiaries are involved in legal proceedings arising in the ordinary course of business or related to indemnities or historical operations. The Company believes it has recorded adequate reserves for these liabilities. The Company discusses its significant legal proceedings below, including ongoing proceedings and those that impacted the Company's results of operations for the periods presented.

Effect of Automatic Stay. The Debtors filed voluntary petitions for relief under the Bankruptcy Code on the Petition Date in the Bankruptcy Court. Each of the Debtors continues to operate its business and manage its property as a debtor-in-possession pursuant to Sections 1107 and 1108 of the Bankruptcy Code. Subject to certain exceptions under the Bankruptcy Code, the filing of the Debtors’ Chapter 11 Cases, pursuant to Section 362(a) of the Bankruptcy Code, automatically enjoined, or stayed, among other things, the continuation of most judicial or administrative proceedings or the filing of other actions against or on behalf of the Debtors or their property to recover on, collect or secure a claim arising prior to the Petition Date or to exercise control over property of the Debtors’ bankruptcy estates, unless and until the Bankruptcy Court modifies or lifts the automatic stay as to any such claim. Notwithstanding the general application of the automatic stay described above, governmental authorities may determine to continue actions brought under their police and regulatory powers.

The Debtors have filed notices of the bankruptcy filings and suggestions of stay in the applicable domestic matters involving one or more of the Debtors as discussed below and in Note 20. "Matters Related to the Bankruptcy of Patriot Coal Corporation". It is currently unclear whether or how the Company’s Chapter 11 Cases will affect the liabilities described below and in Note 20 or any other contingent liabilities the Debtors may have.

Litigation Relating to Continuing Operations

Peabody Monto Coal Pty Ltd, Monto Coal 2 Pty Ltd and Peabody Energy Australia PCI Pty Ltd (PEA-PCI). In October 2007, a statement of claim was delivered to Peabody Monto Coal Pty Ltd, a wholly-owned subsidiary of PEA-PCI, then Macarthur Coal Limited, and Monto Coal 2 Pty Ltd, an equity accounted investee, from the minority interest holders in the Monto Coal Joint Venture, alleging that Monto Coal 2 Pty Ltd breached the Monto Coal Joint Venture Agreement and Peabody Monto Coal Pty Ltd breached the Monto Coal Management Agreement. Peabody Monto Coal Pty Ltd is the manager of the Monto Coal Joint Venture pursuant to the Management Agreement. Monto Coal 2 Pty Ltd holds a 51% interest in the Monto Coal Joint Venture. The plaintiffs are Sanrus Pty Ltd, Edge Developments Pty Ltd and H&J Enterprises (Qld) Pty Ltd. An additional statement of claim was delivered to PEA-PCI in November 2010 from the same minority interest holders in the Monto Coal Joint Venture, alleging that PEA-PCI induced Monto Coal 2 Pty Ltd and Peabody Monto Coal Pty Ltd to breach the Monto Coal Joint Venture Agreement and the Monto Coal Management Agreement, respectively. The plaintiffs later amended their claim to allege damages for lost opportunities to sell their joint venture interest. These actions, which are pending before the Supreme Court of Queensland, Australia, seek damages from the three defendants collectively of amounts ranging from $15.6 million Australian dollars to $1.8 billion Australian dollars, plus interest and costs. The defendants dispute the claims and are vigorously defending their positions. Based on the Company's evaluation of the issues and their potential impact, the amount of any future loss cannot be reasonably estimated.

Queensland Bulk Handling Pty Ltd.  On June 30, 2014, QBH filed a statement of claim with the Supreme Court of Queensland, Australia, against Peabody (Wilkie Creek) Pty Limited, an indirect wholly-owned subsidiary of the Company, alleging breach of a CPSA between the parties.  QBH originally sought damages of $113.1 million Australian dollars, plus interest and costs.  However, it later altered its claim to seek a declaration that the Company subsidiary had exercised an option to renew the contract for a further term, and withdrew its claim for money damages.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

On February 27, 2015, the Supreme Court of Queensland, Australia ruled that QBH and the Company subsidiary were bound to enter into a new CPSA upon substantially the same terms as the 2009 CPSA between them. Under the 2009 CPSA, QBH provided services to Peabody (Wilkie Creek) Pty Limited for operations at the Wilkie Creek Mine, which was closed in 2013. The term of the potential new CPSA would commence January 1, 2015 and expire on December 31, 2026 and, assuming substantially the same contractual terms, would require annual minimum payments of approximately $11.8 million Australian dollars. The Company subsidiary appealed this ruling, which was heard by the Court of Appeal on July 30, 2015. On October 23, 2015, the appellate court upheld this ruling and dismissed the appeal. The Company subsidiary was ordered to pay QBH’s costs of the appeal. In February 2016, QBH served costs statements on the Company subsidiary for attorneys' fees for the appeal and trial and the Company subsidiary is in the process of objecting to the amount of those costs.

On December 8, 2015, QBH filed a claim in the Supreme Court of Queensland, Australia seeking specific performance of the Company subsidiary’s obligation to enter into a new CPSA as described above and payment of $11.8 million Australian dollars representing amounts invoiced by QBH from January through November 2015, plus additional amounts for interest and attorney fees. On January 29, 2016, the Company subsidiary filed a defense to these claims. On February 15, 2016, QBH filed an application for summary judgment, which QBH subsequently agreed to adjourn to a date to be fixed, seeking an order requiring the Company subsidiary to execute a new CPSA and seeking additional amounts invoiced by QBH through February 2016, plus additional interest on these amounts and attorney fees.  On February 29, 2016 QBH filed an amended statement of claim.  The Company subsidiary filed a defense to the amended statement of claim on March 22, 2016.  QBH filed an amended statement of claim in answer to the Company’s amended defense on April 12, 2016. The only change by QBH was to plead that if the Company is correct in its claim that the CPSA was repudiated by the Company and validly terminated by QBH’s acceptance of that repudiation, then QBH claims damages in the alternative. The Company filed an amended defense on May 3, 2016. On May 25, 2016, QBH filed a reply and answer to the Company subsidiary’s amended defense.

As the ultimate impact of the litigation was subject to a wide range of uncertainty, the Company recognized a charge of $9.7 million to discontinued operations during 2015, of which $7.6 million was recorded in the nine months ended September 30, 2015. In September 2016, a settlement was reached under which the Company agreed to pay $13.0 million Australian dollars ($9.9 million USD) to QBH in a full and final settlement of all claims each party had against the other in relation to the CPSA litigation.   A deed of settlement was executed by the parties and the settlement amount was paid to QBH on September 30, 2016.

Lori J. Lynn Class Action. On June 11, 2015, a former Peabody Investments Corp. (PIC) employee filed a putative class action lawsuit in the United States District Court, Eastern District of Missouri on behalf of three of the Company’s or its subsidiaries' 401(k) retirement plans and certain participants and beneficiaries of the plans. The lawsuit, which was brought against Peabody Energy Corporation (PEC), Peabody Holding Company, LLC (PHC), PIC and a number of the Company’s and PIC’s current and former executives and employees, alleges breach of fiduciary duties and seeks monetary damages under the Employee Retirement Income Security Act of 1974 (ERISA) relating to the offering of the Peabody Energy Stock Fund as an investment option in the 401(k) retirement plans.

On September 8, 2015, the plaintiffs filed an amended complaint which, among other things, named a new plaintiff and named all of the current members and two former members of the relevant boards of directors as defendants. The class period (December 2012 to present) remains unchanged. On November 9, 2015, the defendants filed a motion seeking dismissal of all claims.

Plaintiffs filed a second amended complaint on March 11, 2016 that included new allegations against the Company related to the Company's disclosure to investors of risks associated with climate change and related legislation and regulations. The second amended complaint also added the three committees responsible for administering the three 401(k) retirement plans at issue and dropped several individual defendants, including current directors of PEC's board of directors. As a result of filing the Chapter 11 Cases, the plaintiffs voluntarily dismissed the three Debtor defendants (PEC, PIC and PHC) and elected to proceed against the individual defendants and the three named committees with the second amended complaint.

CNTA Dispute. On May 20, 2016, the Company filed a complaint and a request for declaratory judgment in the Bankruptcy Court  against Citibank, N.A. (in its capacity as Administrative Agent under the Company’s 2013 Credit Facility), among others, regarding  the extent of certain collateral and secured claims of certain prepetition creditors. On June 13, 2016, Citibank, N.A. filed an answer and counter-claim for declaratory judgment.  On June 14, 2016, two motions to intervene were filed, one from the Creditors' Committee and another from a group of creditors holding $1.65 billion in face value of the Company's Senior Notes (as indicated in their motion). On June 20, 2016, the Bankruptcy Court entered an order granting the Debtors' motion requesting that the Bankruptcy Court direct all parties to the proceeding to participate in non-binding mediation. The intervention motions were granted on July 7, 2016. On October 7, 2016, a group of creditors holding approximately $287.4 million in face value of the Company’s Senior Secured Second Lien Notes (as indicated in their motion) filed a motion to intervene. The Bankruptcy Court heard oral arguments related to the parties’ motions for summary judgment on September 12, 2016 and subsequently vacated the previously scheduled trial dates and deferred ruling on the matter while the parties continue with mediation. The result of the CNTA Dispute could impact respective recoveries for secured and unsecured creditors in the Chapter 11 Cases.

APS/PacifiCorp Litigation. The Arizona Public Service Company (APS) and PacifiCorp filed a motion in the Bankruptcy Court seeking authorization to allow it to terminate a coal sales agreement, which accounts for approximately half of the Company's El Segundo Mine sales volume. The Company filed a complaint for APS’s and PacifiCorp’s violation of the automatic stay applicable to the Chapter 11 Cases and breach of the coal sales agreement. In September 2016, the parties engaged in a court-ordered mediation. On November 2, the Bankruptcy Court entered an order scheduling the matter for trial beginning on February 13, 2017. The Company intends to vigorously pursue its rights under the coal sales agreement, and against APS/PacifiCorp for the violations of the automatic stay and the coal sales agreement.

Berenergy Corporation. The Company has been in a legal dispute with Berenergy Corporation (Berenergy) regarding Berenergy’s access to certain of its underground oil deposits beneath the Company's North Antelope Rochelle Mine and contiguous undisturbed areas. The Company believes that any claims related to this matter constitute prepetition claims. On October 13, 2016, the Sixth Judicial Court in the state of Wyoming (Wyoming Court) entered an order allowing the Company the right to mine through certain wells owned by Berenergy but required the Company to compensate Berenergy for damages of $0.9 million, which the Company has accrued as of September 30, 2016. Further, the Wyoming Court ruled that should Berenergy obtain approval from the Wyoming Oil and Gas Conservation Commission (the Commission) to recover certain secondary deposits beneath the mine’s contiguous undisturbed areas, the Company would be liable to Berenergy for the cost of certain special procedures and equipment required to access the secondary deposits remotely from outside the Company's mine area, which has been estimated as $13.1 million by Berenergy. The Company believes it is not probable that the Commission will approve access to the secondary deposits based on the Company's view of a lack of economic feasibility and certain restrictions on Berenergy's legal claim to the deposits. The Company is also evaluating the impact of the automatic stay resulting from the Chapter 11 Cases on this matter, which could potentially prevent the Wyoming Court from enforcing its ruling. Based upon these factors, the Company has not accrued a liability related to the secondary deposits as of September 30, 2016. On October 21, 2016, Berenergy filed a motion to lift the automatic stay to allow it to appeal the October 13, 2016 Wyoming Court judgment.

Claims, Litigation and Settlements Relating to Indemnities or Historical Operations

Environmental Claims and Litigation Arising From Historical, Non-Coal Producing Operations. Gold Fields Mining, LLC (Gold Fields) is a non-coal producing entity that was previously managed and owned by Hanson plc, the Company's predecessor owner. In a February 1997 spin-off, Hanson plc transferred ownership of Gold Fields to PEC despite the fact that Gold Fields had no ongoing operations and PEC had no prior involvement in the past operations of Gold Fields. Gold Fields is currently one of PEC's subsidiaries. As part of separate transactions, both PEC and Gold Fields also agreed to indemnify Blue Tee with respect to certain claims relating to the historical operations of a predecessor of Blue Tee, which is a former affiliate of Gold Fields. Neither PEC nor Gold Fields had any involvement with the past operations of the Blue Tee predecessor.

Pursuant to the indemnity, Blue Tee has tendered its environmental claims for remediation, past cost and future costs, and/or natural resource damages (Blue Tee Liabilities) to Gold Fields. Although Gold Fields has paid remediation costs as a result of the indemnification obligations, Blue Tee has been identified as a potentially responsible party (PRP) at various designated national priority list (NPL) sites under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and similar statutes. Of these sites where Blue Tee has been identified as a PRP, neither Gold Fields nor PEC is a party to any cleanup orders relating to the operations of Blue Tee’s predecessor. In addition to the NPL sites, Blue Tee has been named a PRP at multiple other sites, where Gold Fields has either paid remediation costs or settled the environmental claims on behalf of Blue Tee. As a result of filing the Chapter 11 Cases, Gold Fields has now stopped paying these remediation costs.

PEABODY ENERGY CORPORATION

(DEBTOR-IN-POSSESSION)

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Environmental assessments for remediation, past and future costs, and/or natural resource damages also have been asserted by the EPA and natural resources trustees against Gold Fields related to historical activities of Gold Fields’ predecessor. Gold Fields has been identified as a PRP at four NPL sites and has been conducting response actions or working with the EPA to resolve past cost recovery claims at these sites pursuant to cleanup orders or other negotiations. As a result of filing the Chapter 11 Cases, Gold Fields has ceased its response actions and other engagements with the EPA at these sites.

Undiscounted liabilities for environmental cleanup-related costs relating to (i) the contractual indemnification obligations owed to Blue Tee and (ii) for the sites noted above for which Gold Fields has been identified as a PRP as a result of the operations of its predecessor, are collectively estimated to be $62.9 million and $66.9 million as of September 30, 2016 and December 31, 2015, respectively, in the condensed consolidated balance sheets. The majority of these estimated costs relate to Blue Tee site liabilities.

Prior to the August 19, 2016 bar date for filing claims in the Chapter 11 Cases, Blue Tee filed an unliquidated, general unsecured claim in the alleged estimated amount of $65.6 million against Gold Fields regarding the Blue Tee Liabilities, additional unliquidated claims in an unknown amount in excess of $150 million at known sites, and further contingent claims at known and unknown sites, including natural resources damages (NRDs) claims alleged, without explanation, to be in the range of $500 million. PEC and Gold Fields plan to contest these claims which they believe to significantly overstate any liabilities that may exist for remediation costs or potential NRDs.

Prior to the October 11, 2016 government bar date for filing claims in the Chapter 11 Cases, several governmental entities including the EPA, the Department of the Interior and several states filed unliquidated, secured and general unsecured claims against PEC and Gold Fields. These claims total in excess of $2.7 billion and allege damages for past and future remediation costs as well as for alleged NRDs at several sites. As noted in the claims, many of the claims are duplicative as they overlap with each other as well as with claims made by Blue Tee. Additionally, PEC and Gold Fields believe the claims significantly overstate any liabilities that may exist for remediation costs or potential NRDs and will contest the claims. The ultimate impact of these matters is subject to a wide range of uncertainties and the Company cannot reasonably estimate its exposure at this time.

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.

(20) Matters Related to the Bankruptcy of Patriot Coal Corporation

In 2012, Patriot filed voluntary petitions for relief under Chapter 11 of 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 Chapter 11 of the Bankruptcy Code in the Eastern District of Virginia and subsequently initiated a process to sell some or 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.

Credit Support

As part of the 2013 Agreement, the Company provided certain credit support to Patriot. The Company has recorded $20.9 million of credit support provided to Patriot as a liability on the Company's condensed consolidated balance sheet as of September 30, 2016, of which $15.7 million was supported by letters of credit.

Black Lung Occupational Disease Liabilities

Patriot has 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 definitive settlement agreement reached in 2013 included Patriot’s affirmance of indemnities provided in the spin-off agreements, including the indemnity relating to such black lung liabilities.

43

PEABODY ENERGY CORPORATION

(DEBTOR-IN-POSSESSION)

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

By statute, the Company remains secondarily liable for the black lung liabilities related to Patriot’s workers employed by former subsidiaries of the Company. 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 at September 30, 2016 was $132.9 million. While the Company has recorded a liability, it intends to review each claim on a case-by-case basis and contest liability 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. The Company estimates that the annual cash cost to fund these potential Black Lung liabilities will range between $10 million and $15 million.

UMWA VEBA Payments

In connection with the 2013 Agreement, the Company was required to provide total payments of $310.0 million, payable over four years through 2017, to partially fund the newly established voluntary employee beneficiary association (VEBA) and settle all Patriot and UMWA claims involving the Patriot bankruptcy. Those payments included an initial payment of $90.0 million made in January 2014, comprised of $70.0 million paid to Patriot and $20.0 million paid to the VEBA, and a payment of $75.0 million made in January 2015 to the VEBA. The settlement agreement also contemplated subsequent payments to be made to the VEBA of $75.0 million in 2016 and $70.0 million in 2017.

The parties agreed to a settlement of the Company’s obligations for payment of the remaining VEBA payments (2016 Settlement Agreement), which was approved by the Missouri Bankruptcy Court on January 5, 2016 and the Virginia Bankruptcy Court on January 6, 2016. Under this settlement, the Company agreed to pay $75 million to the VEBA, payable in equal monthly installments of $7.5 million beginning on January 4, 2016. The remaining monthly installments are due at the beginning of each successive month ending October 2016, and the obligations are supported in full by a letter of credit. As a result of the Company’s Chapter 11 Cases, the Company’s obligations to the VEBA under the 2016 Settlement Agreement are being satisfied by monthly draws on the letter of credit by the VEBA trustees. These monthly VEBA payments will terminate early if the VEBA participants can receive healthcare benefits that are reasonably similar to or greater than healthcare benefits provided under the VEBA as a result of new legislation. As part of the settlement, the Company recognized a gain of $68.1 million during the nine months ended September 30, 2016, which was classified in "Operating costs and expenses" in the unaudited condensed consolidated statement of operations and is included in the Company's Corporate and Other segment results.

UMWA 1974 Pension Plan (UMWA Plan) Litigation

On July 16, 2015, a lawsuit was filed by the UMWA Plan, the UMWA 1974 Pension Trust (Trust) and the Trustees of the UMWA Plan and Trust (Trustees) in the United States District Court for the District of Columbia, against PEC, PHC, a subsidiary of the Company, and Arch Coal, Inc. (Arch). The plaintiffs sought, pursuant to ERISA and the Multiemployer Pension Plan Amendments Act of 1980 (MPPAA), a declaratory judgment that the defendants were obligated to arbitrate any opposition to the Trustees’ determination that the defendants have statutory withdrawal liability as a result of the 2015 Patriot bankruptcy. The plaintiffs' lawsuit claimed that the defendants' withdrawal liability would result in at least $767 million owed to the UMWA Plan. PEC and PHC agreed that arbitration was the proper mechanism to dispute any withdrawal liability.  Accordingly, the plaintiffs moved to dismiss the lawsuit against PEC and PHC without prejudice and the court granted the motion.  

On October 29, 2015, the Trustees of the UMWA Plan issued a withdrawal liability assessment against PEC and PHC in the amount of $644.2 million (October 29 Assessment) on the theory that a principal purpose of the Company’s 2007 spin-off of Patriot was to “evade or avoid” withdrawal liability to the UMWA Plan. The Trustees allege that the Company is therefore liable for Patriot's withdrawal liability due to Patriot terminating certain collective bargaining agreements with the UMWA eight years after the spin-off during Patriot's bankruptcy proceeding. PEC and PHC dispute that the Patriot spin-off was an attempt to evade or avoid any obligation to the UMWA Plan. Since more than five years have elapsed since the spin-off of Patriot, the law exempts the Company from making any payments toward the October 29 Assessment unless and until an arbitrator issues a final decision in favor of the Trustees on the "evade or avoid" theory of liability. 

ERISA provides a process to adjudicate withdrawal liability disputes, which consists of administrative review by the UMWA Plan followed by arbitration, after which either side can appeal to the appropriate United States district court. PEC and PHC initiated the administrative review process with the UMWA Plan on January 26, 2016 and the UMWA Plan denied the request on March 18, 2016.  The UMWA Plan initiated arbitration with the AAA on April 7, 2016 (Pension Arbitration). The filing of the Bankruptcy Petitions on April 13, 2016 automatically stayed the Pension Arbitration.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

On August 15, 2016, the UMWA Plan filed a claim in the Bankruptcy Court against the Debtors related to the October 29 Assessment in the amount of $642.7 million.  On September 8, 2016, the Debtors filed an objection to the claim in the Bankruptcy Court.  In the objection, the Debtors argued that they are not liable to the UMWA Plan and asked the Bankruptcy Court to disallow the claim in its entirety.  

On September 26, 2016, the UMWA Plan filed a motion to lift the automatic stay to allow the UMWA Plan’s claim to be adjudicated through arbitration, not the claims administration process outlined by the Bankruptcy Code, as articulated in the Stipulation (Lift-Stay Motion).  On October 11, 2016, the Debtors objected to the Lift-Stay Motion on the grounds that the UMWA Plan had not established sufficient cause to lift the automatic stay.  A hearing on the Lift-Stay Motion was held on October 18, 2016, and the Bankruptcy Court granted limited relief from the automatic stay until October 28, 2016 to provide the UMWA Plan until October 28, 2016, to receive a written confirmation from the AAA that the AAA could find an arbitrator with sufficient experience who could arbitrate the UMWA Plan's claim and reach a decision, without extension or any exception for cause, by January 26, 2017. On October 25, 2016, the UMWA Plan filed a copy of its correspondence with the AAA and on October 26, 2016, the Bankruptcy Court issued an order lifting the automatic stay to allow arbitration of the claim to proceed. The parties have selected an arbitrator, and the arbitration hearings are scheduled to begin on December 19, 2016.

During the three months ended September 30, 2016, the Company recognized a charge of $35.0 million, consisting of a $10.0 million cash liability and an allowed unsecured claim of $25.0 million, to "Loss from discontinued operations, net of income taxes" in the unaudited condensed consolidated statement of operations as an estimate of the low end of the range of loss. The top end of the range of reasonably possible loss is $642.7 million, which, as noted above, is the total value of the UMWA Plan's claim.

(21) Segment Information

(22)     Supplemental Financial Information

Guarantor / Non-Guarantor

In accordance with the indentures governing the Senior Notes, certain 100% owned U.S. subsidiaries of the Company (each, a Guarantor Subsidiary) have fully and unconditionally guaranteed the Senior Notes, on a joint and several basis. The indentures governing the Senior Notes contain customary exceptions under which a guarantee of a Guarantor Subsidiary will terminate, including (a) the release or discharge of the guarantee of the Company’s 2013 Credit Facility by such Guarantor Subsidiary, except a discharge or release by or as a result of payment under such guarantee, (b) a sale or other disposition, by way of merger, consolidation or otherwise, of all of the capital stock of such Guarantor Subsidiary, and (c) the legal defeasance or discharge of the indentures. Separate financial statements and other disclosures concerning the Guarantor Subsidiaries are not presented because management believes that such information is not material to the holders of the Senior Notes. The following historical financial statement information is provided for the Guarantor/Non-Guarantor Subsidiaries.

(23)     Subsequent Event

On November 3, 2016, Peabody Australia Mining Pty Ltd, one of the Company’s Australian subsidiaries, entered into a definitive share sale and purchase agreement for the sale of all of the equity interests in Metropolitan Collieries Pty Ltd, the entity that owns the Metropolitan mine in New South Wales, Australia and the associated interest in the Port Kembla Coal Terminal, to a subsidiary of South32 Limited (South32). Pursuant to the agreement, the Company will receive cash consideration of $200 million, subject to a customary working capital adjustment. The transaction also includes contingent consideration that enables the Company to share equally with South32 in any revenue above an agreed metallurgical coal price forward curve, after taxes, royalties and appropriate discounts, on all coal sold for the 12 months following completion of the transaction, subject to extension if a minimum amount of coal is not sold during that period. The closing of the transaction is currently anticipated to occur in the first quarter of 2017 and is conditional on receipt of approval from the Australian Competition and Consumer Commission.

The Company determined that, as a result of entering the transaction, and the approval of the Company’s Board of Directors of such a transaction in October 2016, the Metropolitan mine was deemed to meet held-for-sale accounting criteria in the fourth quarter of 2016. Accordingly, the Company expects to record an after-tax impairment charge of approximately $180 million to write down the assets to their estimated selling price, which is the best estimate of fair value under a held-for-sale accounting model. The Company expects to report the impairment charge in its Annual Report on Form 10-K for the year ended December 31, 2016.

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

Cautionary Notice Regarding Forward-Looking Statements

This report includes statements of our expectations, intentions, plans and beliefs that constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 and are intended to come within the safe harbor protection provided by those sections. These statements relate to future events or our future financial performance, including, without limitation, the section captioned “Outlook” in this Item 2. We use 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 our 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 we believe 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 our control. Factors that could affect our results or an investment in our securities include, but are not limited to:

Factors related to our Chapter 11 Cases (as defined below)

• our ability to obtain Bankruptcy Court (as defined below) approval with respect to motions or other requests made to the Bankruptcy Court in the Chapter 11 Cases (as defined below), including maintaining strategic control as debtor-in-possession;

• our ability to negotiate, develop, confirm and consummate a plan of reorganization;

• the effects of the Chapter 11 Cases on our operations, including customer, supplier, banking, insurance and other relationships and agreements;

• Bankruptcy Court rulings in the Chapter 11 Cases as well as the outcome of all other pending litigation and the outcome of the Chapter 11 Cases in general;

• the length of time that we will operate under Chapter 11 protection and the continued availability of operating capital during the pendency of the proceedings;

• risks associated with third-party motions in the Chapter 11 Cases, which may interfere with our ability to confirm and consummate a plan of reorganization and restructuring generally;

• increased advisory costs to execute a plan of reorganization;

• the impact of the New York Stock Exchange's (NYSE) delisting of our common stock on the liquidity and market price of our common stock and on our ability to access the public capital markets;

• the likelihood that our common stock will be cancelled and extinguished upon confirmation of a proposed plan of reorganization with no payments made to the holders of our common stock;

• the volatility of the trading price of our common stock and the absence of correlation between any increases in the trading price and our expectation that the common stock will be cancelled and extinguished upon confirmation of a proposed plan of reorganization with no payments made to the holders of our common stock;

• our ability to continue as a going concern, including our ability to confirm a plan of reorganization that restructures our debt obligations to address our liquidity issues and allow emergence from the Chapter 11 Cases;

• our ability to access adequate debtor-in-possession financing or use cash collateral;

• the effect of the Chapter 11 Cases on our relationships with third parties, regulatory authorities and employees;

• the potential adverse effects of the Chapter 11 Cases on our liquidity, results of operations, or business prospects;

• our ability to execute our business and restructuring plan;

• increased administrative and legal costs related to the Chapter 11 Cases and other litigation and the inherent risks involved in a bankruptcy process;

• the cost, availability and access to capital and financial markets, including the ability to secure new financing after emerging from the Chapter 11 Cases;

• the risk that the Chapter 11 Cases will disrupt or impede our international operations, including our Australian operations;

61

Other factors

• competition in the energy markets and supply and demand for our coal products, including the impact of alternative energy sources, such as natural gas and renewables, global steel demand and the downstream impact on metallurgical coal prices, and lower demand for our products by electric power generators;

• our ability to successfully consummate planned divestitures;

• our ability to appropriately secure our obligations for reclamation, federal and state workers’ compensation, federal coal leases and other obligations related to our operations, including our ability to utilize self-bonding and/or successfully access the commercial surety bond market;

• customer procurement practices and contract duration;

• the impact of weather and natural disasters on demand, production and transportation;

• reductions and/or deferrals of purchases by major customers and our ability to renew sales contracts;

• credit and performance risks associated with customers, suppliers, contract miners, co-shippers, and trading, bank and other financial counterparties;

• geologic, equipment, permitting, site access, operational risks and new technologies related to mining;

• transportation availability, performance and costs;

• availability, timing of delivery and costs of key supplies, capital equipment or commodities such as diesel fuel, steel, explosives and tires;

• impact of take-or-pay arrangements for rail and port commitments for the delivery of coal;

• successful implementation of business strategies, including, without limitation, the actions we are implementing to improve our organization and respond to current market conditions;

• negotiation of labor contracts, employee relations and workforce availability, including, without limitation, attracting and retaining key personnel;

• our ability to comply with financial and other restrictive covenants in various agreements, including the DIP Credit Agreement (as defined below);

• changes in postretirement benefit and pension obligations and their related funding requirements;

• replacement and development of coal reserves;

• effects of changes in interest rates and currency exchange rates (primarily the Australian dollar);

• effects of acquisitions or divestitures;

• economic strength and political stability of countries in which we have operations or serve customers;

• legislation, regulations and court decisions or other government actions, including, but not limited to, new environmental and mine safety requirements, changes in income tax regulations, sales-related royalties, or other regulatory taxes and changes in derivative laws and regulations;

• our ability to obtain and renew permits necessary for our operations;

• litigation or other dispute resolution, including, but not limited to, claims not yet asserted;

• any additional liabilities or obligations that we may have as a result of the bankruptcy of Patriot Coal Corporation, including, without limitation, as a result of litigation filed by third parties in relation to that bankruptcy;

• terrorist attacks or security threats, including, but not limited to, cybersecurity breaches;

• impacts of pandemic illnesses; and

• other risks and factors detailed in our reports filed with the SEC; including, but not limited to, those discussed in Part II, Item 1. "Legal Proceedings," of this Quarterly Report on Form 10-Q and Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2015 and in Part II, Item 1A. "Risk Factors" in our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2016 and June 30, 2016.

When considering these forward-looking statements, you should keep in mind the cautionary statements in this document and in our 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 our results contained in Item 1A. “Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2015. These forward-looking statements speak only as of the date on which such statements were made, and we undertake no obligation to update these statements except as required by federal securities laws.

Overview

We are the world’s largest private sector coal company by volume. As of September 30, 2016, we owned interests in 26 active coal mining operations located in the United States (U.S.) and Australia. We have a majority interest in 25 of those mining operations and a 50% equity interest in Middlemount Coal Pty Ltd. (Middlemount), which owns the Middlemount Mine in Queensland, Australia. In addition to our mining operations, we market and broker coal from other coal producers, both as principal and agent, and trade coal and freight-related contracts.

In 2015, we produced and sold 208.7 million and 228.8 million tons of coal, respectively, from continuing operations. During that period, 78% of our total sales (by volume) were to U.S. electricity generators, 21% were to customers outside the U.S. and 1% were to the U.S. industrial sector, with approximately 88% of our worldwide sales (by volume) delivered under long-term contracts.

We conduct business through six operating segments: Australian Metallurgical Mining, Australian Thermal Mining, Midwestern U.S. Mining, Powder River Basin Mining, Western U.S. Mining and Trading and Brokerage. Refer to Note 21. "Segment Information" to the accompanying unaudited condensed consolidated financial statements for further information surrounding those segments and the components of our Corporate and Other segment.

Filing Under Chapter 11 of the United States Bankruptcy Code

On April 13, 2016 (the Petition Date), Peabody Energy Corporation and its affiliates (Peabody or the Company) and a majority of its wholly owned domestic subsidiaries as well as one international subsidiary in Gibraltar (the Filing Subsidiaries, and together with Peabody, the Debtors) filed voluntary petitions for reorganization (the petitions collectively, the Bankruptcy Petitions) under Chapter 11 of Title 11 of the U.S. Code (the Bankruptcy Code) in the United States Bankruptcy Court for the Eastern District of Missouri (the Bankruptcy Court). Our Australian operations and other international subsidiaries are not included in the filings. The Debtors' Chapter 11 cases (collectively, the Chapter 11 Cases) are being jointly administered under the caption In re Peabody Energy Corporation, et al., Case No. 16-42529 (Bankr. E.D. Mo.). The Debtors continue to operate their businesses as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.

The filings of the Bankruptcy Petitions constituted an event of default under our prepretition credit agreement as well as the indentures governing certain of our debt instruments, as further described in Note 13. "Current and Long-term Debt" to the condensed consolidated financial statements, and all unpaid principal and accrued and unpaid interest due thereunder became immediately due and payable. Any efforts to enforce such payment obligations are automatically stayed as a result of the Bankruptcy Petitions and the creditors' rights of enforcement are subject to the applicable provisions of the Bankruptcy Code.

Additionally, on the Petition Date, the NYSE determined that Peabody’s common stock was no longer suitable for listing pursuant to Section 8.02.01D of the NYSE’s Listed Company Manual, and trading in our common stock was suspended. Our common stock began trading on the OTC Pink Sheets marketplace under the symbol BTUUQ on April 14, 2016. Following the Petition Date, the NYSE formally de-listed Peabody's common stock.

On April 14, 2016, the Bankruptcy Court approved several motions (First Day Motions), including motions (i) authorizing the Debtors to pay prepetition wages and benefits for its workforce (Employee Motion), in part, (ii) prohibiting utilities from discontinuing service and authorizing the Debtors to provide adequate assurance deposits, (iii) authorizing the Debtors to pay prepetition obligations to certain critical vendors on an interim basis (Critical Vendor Motion), (iv) authorizing the Debtors to maintain their existing cash management system on an interim basis (Cash Management Motion), (v)  authorizing certain Debtors to continue selling and contributing receivables and related rights pursuant to a securitization facility on an interim basis (Securitization Motion) and (vi) authorizing the Debtors to enter into an $800 million debtor-in-possession financing facility (DIP Credit Agreement) on an interim basis (DIP Motion).

Pursuant to Section 362 of the Bankruptcy Code, the filing of the Bankruptcy Petitions automatically stayed most actions against the Debtors, including actions to collect indebtedness incurred prior to the Petition Date or to exercise control over the Debtors’ property. Subject to certain exceptions under the Bankruptcy Code, the filing of the Debtors’ Chapter 11 Cases also automatically stayed the continuation of most legal proceedings, including certain of the third party litigation matters described in Note 19. "Commitments and Contingencies" and Note 20. "Matters Related to the Bankruptcy of Patriot Coal Corporation" of this report or the filing of other actions against or on behalf of the Debtors or their property to recover on, collect or secure a claim arising prior to the Petition Date or to exercise control over property of the Debtors’ bankruptcy estates, unless and until the Bankruptcy Court modifies or lifts the automatic stay as to any such claim. Notwithstanding the general application of the automatic stay described above, governmental authorities may determine to continue actions brought under their police and regulatory powers.

63

The U.S. Trustee for the Eastern District of Missouri filed a notice appointing an official committee of unsecured creditors (the Creditors' Committee) on April 29, 2016. The Creditors’ Committee represents all unsecured creditors of the Debtors and has a right to be heard on all matters that come before the Bankruptcy Court.

On May 17, 2016, the Bankruptcy Court approved various of the First Day Motions on a final basis, including the Employee Motion, Critical Vendor Motion, Cash Management Motion, Securitization Motion and DIP Motion. At the May 17 hearing, the Bankruptcy Court also approved various motions (i) authorizing the Debtors’ retention of various professionals, (ii) establishing procedures for the retention of ordinary course professionals, (iii) establishing procedures for the sale of de minimis assets and (iv)  authorizing the Debtors to consummate the sale of the Debtors’ equity interests in Lively Grove Energy Partners, LLC, a Debtor, and dismissing Lively Grove Energy Partners, LLC’s current chapter 11 case.

65

On October 11, 2016, the Bankruptcy Court approved a stipulation and agreed order filed by the Debtors seeking the authority to enter into that certain Amendment No. 4 and Consent Under Superpriority Secured Debtor-in-Possession Credit Agreement (the DIP Amendment). The DIP Amendment modifies certain of the milestones under the DIP Credit Agreement, including (i) a modification to the deadline by which the Bankruptcy Court shall enter an order determining the issues being adjudicated in the CNTA Adversary Proceeding (the CNTA Order) to provide that the Bankruptcy Court shall have entered the CNTA Order by no later than November 23, 2016; (ii) a modification to the deadlines for Peabody to file an Acceptable Reorganization Plan (as defined in the DIP Credit Agreement) and related disclosure statement to provide that Peabody must file these by, or on, the date that is the later of (a) 30 days after the entry of the CNTA Order and (b) December 14, 2016; and (iii) a modification to the deadline by which the Bankruptcy Court shall enter an order approving the Debtors' disclosure statement to provide that the Bankruptcy Court shall have entered this order by no later than January 31, 2017. The DIP Credit Agreement also contains restrictions on the ability of Peabody Global Funding, LLC (Global Funding) to amend or waive provisions under the Intercompany Loan Agreement (as defined in the DIP Credit Agreement) in a manner that would release or subordinate more than 50% of the collateral thereunder. The DIP Amendment modifies these restrictions to expressly allow Global Funding to amend or waive provisions under the Intercompany Loan Agreement to permit the release or subordination of collateral thereunder, including as a result of potential asset sales, of up to $250 million in cash proceeds in the aggregate over the life of the Intercompany Loan Agreement.

On October 14, 2016, the Debtors filed four omnibus objections to certain proofs of claim.

On October 18, 2016, the Bankruptcy Court granted several motions, including (i) an application to retain additional professionals, (ii) a motion to reject a certain contract, (iii) the Equipment Lease Procedures Motion, and (iv) two motions related to the Debtors' insurance programs authorizing the Debtors to (a) enter into a new postpetition property policy with an affiliate(s) of American International Group, Inc. and (b) assume certain existing policies and enter into a new workers compensation insurance policy with ACE American Insurance Company, including its affiliated companies. Additionally, the Bankruptcy Court partially and conditionally granted the motion for relief from the automatic stay filed on September 26, 2016 by the UMWA Plan. The Bankruptcy Court lifted the automatic stay to provide the UMWA Plan until October 28, 2016, to receive a written confirmation from the American Arbitration Association (the AAA) that the AAA could find an arbitrator with sufficient experience who could arbitrate the UMWA Plan's claim and reach a decision, without extension or any exception for cause, by January 26, 2017.

On October 21, 2016, Berenergy Corporation filed a motion to lift the automatic stay to allow it to appeal a final judgment entered in the Sixth Judicial District Court in the state of Wyoming, as discussed in more detail in Note 19 "Commitments and Contingencies".

On October 24, 2016, the Debtors filed a motion to assume or reject non-residential leases to which the Debtors are a party.

On October 25, 2016, the UMWA Plan filed a copy of its correspondence with the AAA and on October 26, 2016, the Bankruptcy Court issued an order lifting the automatic stay to allow arbitration of the claim to proceed. The parties have selected an arbitrator, and the arbitration hearings are scheduled to begin on December 19, 2016.

On October 26, 2016, the Debtors filed a motion to assume certain executory contracts to which certain Debtors are a party, as well as an omnibus motion for the rejection of certain executory contracts regarding overriding royalties.

As a result of the Bankruptcy Petitions, the realization of the Debtors’ assets and the satisfaction of liabilities are subject to significant uncertainty. For the Debtors to emerge successfully from Chapter 11, they must obtain the Bankruptcy Court’s approval of a plan of reorganization, which will enable them to transition from Chapter 11 into ordinary course operations as reorganized entities outside of bankruptcy. A plan of reorganization determines the rights and treatment of claims of various creditors and equity security holders, and is subject to the ultimate outcome of negotiations and Bankruptcy Court decisions ongoing through the date on which the plan of reorganization is confirmed.

66

The Debtors intend to propose a plan of reorganization on or prior to the applicable date required under the Bankruptcy Code and in accordance with milestones set forth in the DIP Credit Agreement (as set forth below in Note 13. "Current and Long-term Debt"), as the same may be extended with approval of the Bankruptcy Court. As noted above, the Debtors and the parties to the DIP Credit Agreement entered into the DIP Amendment, which modified certain milestone dates. The Debtors presently expect that any proposed plan of reorganization will provide, among other things, for mechanisms for the settlement of claims against the Debtors’ estates, treatment of the Debtors' existing equity and debt holders, and certain corporate governance and administrative matters pertaining to the reorganized Debtors. A proposed plan of reorganization filed with the Bankruptcy Court likely will incorporate provisions arising out of the Debtors' discussions with their creditors and other interested parties, and likely will be further revised thereafter. There can be no assurance that the Debtors will be able to secure approval for their proposed plan of reorganization from the Bankruptcy Court or execute such plan. Further, a plan of reorganization is likely to materially change the amounts and classifications of assets and liabilities reported in our condensed consolidated financial statements. Although it is uncertain at this stage if any proposed plan of reorganization would allow for distributions with respect to equity or other securities, it is likely that equity securities will be cancelled and extinguished upon confirmation of a proposed plan of reorganization by the Bankruptcy Court, and that the holders thereof would not be entitled to receive, and would not receive or retain, any property or interest in property on account of such equity interests.

Peabody believes it will require a significant restructuring of its balance sheet in order to continue as a going concern. Our ability to continue as a going concern is dependent upon, among other things, its ability to become profitable and maintain profitability, its ability to access sufficient liquidity and its ability to successfully implement its Chapter 11 plan of reorganization. The accompanying condensed consolidated financial statements are prepared on a going concern basis and do not include any adjustments that might be required if the we were unable to continue as a going concern.

Results of Operations

Reverse Stock Split

Pursuant to the authorization provided at a special meeting of our stockholders held on September 16, 2015, we completed a 1-for-15 reverse stock split of the shares of our common stock on September 30, 2015 (the Reverse Stock Split). As a result of the Reverse Stock Split, every 15 shares of issued and outstanding common stock were combined into one issued and outstanding share of common stock, without any change in the par value per share. Our common stock began trading on a reverse stock split-adjusted basis on the NYSE on October 1, 2015. All share and per share data included in this report has been retroactively restated to reflect the Reverse Stock Split.

Non-U.S. GAAP Financial Measures

The following discussion of our results of operations includes references to and analysis of Adjusted EBITDA, which is a financial measure not recognized in accordance with U.S. generally accepted accounting principles (GAAP). These financial measures are not intended to serve as alternatives to U.S. GAAP measures of performance and may not be comparable to similarly-titled measures presented by other companies.

Adjusted EBITDA is used by management as the primary metric to measure our segments’ operating performance. We also believe non-GAAP performance measures are used by investors to measure our operating performance and lenders to measure our ability to incur and service debt.

Adjusted EBITDA is defined as (loss) income from continuing operations before deducting net interest expense, income taxes, asset retirement obligation expense, depreciation, depletion and amortization and reorganization items, net. Adjusted EBITDA is also adjusted for certain discrete items, which are reflected in the reconciliation below, that management excluded in analyzing the segment's operating performance. Adjusted EBITDA is not intended to serve as an alternative to GAAP measures of performance and may not be comparable to similarly-titled measures presented by other companies.

A reconciliation of Adjusted EBITDA to its most comparable measure under GAAP is included in Note 21. "Segment Information" of the accompanying unaudited condensed consolidated financial statements.

Three and Nine Months EndedSeptember 30,2016 Compared to the Three and Nine Months EndedSeptember 30,2015

Summary

Demand for seaborne metallurgical coal for the nine months ended September 30, 2016 was adversely impacted by a 0.5% decrease in worldwide steel production compared to the same period in the prior year, according to data recently published by the World Steel Association (WSA). However, China coal imports have strengthened since March following policy measures in China that have reduced domestic coal production and on stronger than expected China steel production and power generation. International seaborne metallurgical and thermal coal prices have also increased sharply, reaching multi-year highs driven by tightening coal supply and improved coal import demand from China. Benchmark pricing for seaborne premium high quality hard coking coal (HQHCC) and premium low volatile pulverized coal injections products (LV PCI) for the first, second, third and fourth quarters of 2016 and 2015 were as follows (on a per tonne basis):

Contract Commencement Month:	HQHCC				Price Increase (Decrease)		LV PCI				Price Increase (Decrease)
	2016		2015		%		2016		2015		%
January	$	81	$	117	(31	)%	$	69	$	99	(30	)%
April	$	84	$	110	(24	)%	$	73	$	93	(22	)%
July	$	93	$	93	—	%	$	75	$	73	3	%
October	$	200	$	89	125	%	$	133	$	71	87	%

During the three months ended September 30, 2016, HQHCC and Newcastle index thermal coal realized the following spot pricing:

	High		Low		Average		September 30, 2016
High quality hard coking coal	$	213	$	92	$	136	$	213
Newcastle index thermal coal	$	73	$	58	$	66	$	72

In the U.S., electricity generation from coal decreased 13% during the nine months ended September 30, 2016 compared to the same period in 2015, according to the U.S. Energy Information Administration (EIA). U.S. electricity generation from coal was unfavorably affected during that period by coal-to-gas switching due to comparatively low natural gas prices during the first quarter of 2016, high coal stockpiles, and lower heating-degree days due to mild winter weather.

Our revenues decreased during the three and nine months ended September 30, 2016 compared to the same periods in 2015 ($211.8 millionand $1,021.6 million, respectively) primarily due to lower realized pricing and lower sales volumes driven by the demand and production factors mentioned above.

To mitigate the impact of lower coal pricing, we have continued to drive operational efficiencies, optimize production across our mining platform and control expenses at all operational and administrative levels of the organization, which has contributed to year-over-year decreases in our operating costs and expenses (three months, $189.2 million; nine months, $793.2 million). Also included in operating results for the nine months ended September 30, 2016 are aggregate restructuring charges of $15.5 million, recognized in connection with certain actions initiated to reduce headcount and costs across our operating segments and administrative functions, which actions are expected to better align our workforce with our near-term market outlook and improve our cost position moving forward.

68

Net loss attributable to common stockholders improved for the three months and nine months ended September 30, 2016 compared to the same periods in the prior year by $169.2 millionand$990.5 million, respectively. The comparative improvement in net loss attributable to common stockholders was primarily driven by Patriot bankruptcy-related charges associated with black lung liabilities and the UMWA Combined Benefit Fund totaling $155.1 million recognized in the third quarter of 2015 as compared to a charge of $35.0 million recorded in the current period for the UMWA 1974 Pension Plan. Results for the nine month period were further impacted by significant asset impairment charges recorded in the prior year and the resulting reduction in current year depreciation and depletion owing to the impairment charges as well as from reduced sales volumes, reduced interest expense attributable to the accrual of adequate protection payments in lieu of contractual interest on our first lien debt obligations subsequent to filing the Bankruptcy Petitions, and debt extinguishment expenses in the prior year periods related to the early refinancing of our 7.375% Senior Notes due 2016 (the 2016 Senior Notes). Adjusted EBITDA of $108.3 million and $188.9 million for the three and nine months ended September 30, 2016, respectively, reflected year-over-year decreases of $20.7 million and $192.7 million, respectively.

As of September 30, 2016, our available liquidity was approximately $1.2 billion. Refer to the "Liquidity and Capital Resources" section contained within this Item 2 for a further discussion of factors affecting our available liquidity.

Australian Metallurgical Mining. Segment revenues decreased during the three and nine months ended September 30, 2016 compared to the same periods in the prior year due to unfavorable volume and mix variances (three months, $61.5 million; nine months, $134.9 million). The volume decrease reflected lower sales volumes from our Moorvale and Millennium Mines due to weather impacts and lower production at our North Goonyella and Metropolitan Mines resulting from longwall moves. The year-to-date period was further impacted by lower realized coal prices (nine months, $106.9 million).

Australian Thermal Mining. Segment revenues decreased during the three and nine months ended September 30, 2016 compared to the same periods in the prior year due to lower realized coal prices (three months, $12.1 million; nine months, $79.5 million), partially offset by favorable volume and mix variances (three months, $4.7 million; nine months, $25.7 million) which were attributable to higher volume from our Wambo Mine and higher margin export sales from our Wilpinjong Mine.

Powder River Basin Mining. Segment revenues decreased during the three and nine months ended September 30, 2016 compared to the same periods in the prior year due to unfavorable volume and mix variances (three months, $30.3 million; nine months, $345.7 million) which were driven by lower demand across all mines in the segment (three months, 2.5 million tons; nine months, 23.1 million tons).

Western U.S. Mining. Segment revenues decreased during the three and nine months ended September 30, 2016 compared to the same periods in the prior year predominately due to unfavorable volume and mix variances (three months, $9.3 million; nine months, $133.5 million) primarily due to lower demand resulting from lower natural gas prices during the first quarter of 2016, mild winter weather, higher customer inventory levels and the impact of the ongoing litigation with Arizona Public Service Company and PacifiCorp that is further described in Note 19. "Commitments and Contingencies" of the accompanying unaudited condensed consolidated financial statements.

Segment revenues decreased during the three and nine months ended September 30, 2016 compared to the same periods in the prior year due to unfavorable volume and mix variances (three months, $28.1 million; nine months, $134.0 million) due to lower demand and lower realized coal pricing (three months, $10.3 million; nine months, $34.6 million) that resulted from the repricing of certain long-term supply contracts.

Trading and Brokerage. Segment revenues decreased during the three and nine months ended September 30, 2016 compared to the prior year due to lower physical volumes shipped due to the opportunity-limiting impact of depressed coal pricing and unfavorable mark-to-market earnings from financial contract trading activities. We expect a significant portion of the unfavorable mark-to-market earnings to be offset in future periods upon the delivery of physical shipments which economically hedge the financial positions that related to the losses.

Results from continuing operations before income taxes improved for the three and nine months ended September 30, 2016 compared to the prior year primarily due to asset impairment and early debt extinguishment charges recorded during the nine months ended September 30, 2015, improved Corporate and Other Adjusted EBITDA, decreased depreciation, depletion and amortization expenses, and decreased interest expenses. Those factors were partially offset by lower Segment Adjusted EBITDA and reorganization items, net recorded during the three and nine months ended September 30, 2016.

Australian Metallurgical Mining. Segment Adjusted EBITDA decreased during the three months ended September 30, 2016 compared to the prior year due to lower volumes at our North Goonyella and Metropolitan Mines ($13.1 million) resulting from longwall moves and at our Millennium and Coppabella Mines due to weather impacts ($12.2 million) partially offset by improved coal pricing, net of sales-related costs ($12.8 million). Segment Adjusted EBITDA decreased during the nine months ended September 30, 2016 compared to the prior year due to lower coal pricing, net of sales-related costs ($98.9 million) and lower volume across the segment caused by lower demand and the impact of longwall moves ($41.1 million), partially offset by the net impact of favorable exchange rate movements ($28.1 million).

Australian Thermal Mining. Segment Adjusted EBITDA during the three months ended September 30, 2016 was in line with the prior year as lower coal pricing, net of sales-related costs ($11.1 million), was offset by weather impacts and mine sequencing at our Wambo Mine relative to the prior year period ($13.6 million). Segment Adjusted EBITDA decreased during the nine months ended September 30, 2016 compared to the prior year due to lower coal pricing, net of sales-related costs ($73.2 million), partially offset by an increase in volume, including higher margin export sales from our Wilpinjong Mine ($20.2 million), production efficiencies attributable to mine sequencing ($29.3 million), and the net impact of favorable exchange rate movements ($10.8 million).

Powder River Basin Mining. Segment Adjusted EBITDA increased during the three months ended September 30, 2016 compared to the same period in the prior year due to reductions in materials, services and repairs costs resulting from our ongoing cost containment initiatives ($14.6 million), impact of mine sequencing, primarily at our North Antelope Rochelle Mine ($8.1 million) and lower diesel fuel and explosives pricing ($2.4 million), partially offset by lower coal pricing, net of sales-related costs ($19.6 million). Segment Adjusted EBITDA decreased during the nine months ended September 30, 2016 compared to the same period in the prior year due to lower volume driven by demand reduction ($81.2 million) and the impact of mine sequencing, primarily at our North Antelope Rochelle Mine ($27.3 million), partially offset by reductions in materials, services and repairs costs resulting from our ongoing cost containment initiatives ($38.2 million) and lower diesel fuel and explosives pricing ($14.7 million).

Western U.S. Mining. Segment Adjusted EBITDA decreased during the three and nine months ended September 30, 2016 compared to the same periods in the prior year primarily due to lower volume driven by demand reduction (three months, $17.4 million; nine months, $60.5 million).

Midwestern U.S. Mining. Segment Adjusted EBITDA decreased during the three months ended September 30, 2016 compared to the prior year due to lower coal pricing, net of sales-related costs ($8.6 million) and lower volume driven by market demand reduction ($7.8 million). Segment Adjusted EBITDA decreased during the nine months ended September 30, 2016 compared to the prior year due to lower volume driven by demand reduction ($50.2 million) and lower coal pricing, net of sales-related costs ($31.4 million), partially offset by favorable materials, services and repairs costs resulting from our ongoing cost containment initiatives ($15.3 million) and favorable pricing and usage of fuel and explosives ($10.5 million).

Trading and Brokerage. Segment Adjusted EBITDA decreased during the three and nine months ended September 30, 2016 compared to the prior year primarily due to the impact of decreased revenues described above, partially offset by lower selling and administrative expenses resulting from our ongoing cost containment initiatives.

⁽¹⁾  Includes gains on certain surplus coal reserve and surface land sales and property management costs and revenues.

⁽²⁾  Includes results from equity affiliates (before the impact of related changes in deferred tax asset valuation allowance and amortization of basis difference), costs associated with past mining activities, certain coal royalty expenses, gains (losses) on certain asset disposals, minimum charges on certain transportation-related contracts and expenses related to our other commercial activities.

The improvement in selling and administrative expenses during the three and nine months ended September 30, 2016 compared to the same periods in the prior year largely reflected the impact of our ongoing cost containment initiatives, including past restructuring activities. Restructuring charges decreased during the three and nine months ended September 30, 2016 compared to the same periods in the prior year due to the elimination of a greater number of our more highly compensated positions at corporate and regional offices during the first half of 2015. The favorable variances associated with corporate hedging results, which includes foreign currency and commodity hedging, resulted from the year-over-year strengthening of the Australian dollar. During the nine months ended September 30, 2016, a gain of $68.1 million was recognized in connection with the settlement of all Patriot and United Mine Workers of America (UMWA) claims associated with the Patriot bankruptcy as further described in Note 20. "Matters Related to the Bankruptcy of Patriot Coal Corporation" of the accompanying unaudited condensed consolidated financial statements. The favorable variances associated with other items, net is primarily attributable to lower charges on certain transportation-related contracts as compared to prior periods ($8.6 million) during the three months ended September 30, 2016 and a $6.2 million gain recorded in connection with the sale of our 5.06% participation interest in the Prairie State Energy Campus to the Wabash Valley Power Association for $57.1 million as further described in Note 16. "Other Events" of the accompanying unaudited condensed consolidated financial statements.

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

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
	2016		2015		2016		2015
Australian Metallurgical Mining	$	4.29	$	4.10	$	4.24	$	5.19
Australian Thermal Mining	2.59		2.69		2.61		2.58
Powder River Basin Mining	0.69		0.69		0.73		0.69
Western U.S. Mining	0.91		0.95		0.91		0.93
Midwestern U.S. Mining	0.54		0.49		0.52		0.46

The decrease in depreciation, depletion and amortization expense during the three and nine months ended September 30, 2016 compared to the prior year reflected lower sales volumes from our mining platform. Depreciation, depletion and amortization was also impacted compared to the prior year by a reduction in the asset bases at several of our mines due to impairment charges recognized during 2015.

Selling and Administrative Expenses Related to Debt Restructuring. The general and administrative expenses related to debt restructuring recorded during the nine months ended September 30, 2016 related to legal and other expenditures made in connection with debt restructuring initiatives prior to the Debtors' filing of the Bankruptcy Petitions.

Asset Impairment. Refer to Note 5. "Asset Impairment" in the accompanying unaudited condensed consolidated financial statements for information surrounding the impairment charges recorded during the nine months ended September 30, 2016 and 2015.

Interest Expense. The decrease in interest expense for the three and nine months ended September 30, 2016 compared to the same periods in the prior year is primarily due to the impact of our filing of the Bankruptcy Petitions, specifically only accruing adequate protection payments subsequent to the Petition Date to certain secured lenders and other parties in accordance with Section 502(b)(2) of the Bankruptcy Code, partially offset by increased interest recorded in connection with additional prepetition borrowings under the 2013 Revolver and increased expense related to additional letters of credit issued in support of various obligations.

Loss on Early Debt Extinguishment. The loss on early debt extinguishment charges recorded during the nine months ended September 30, 2015 related to the repurchase of $566.9 million aggregate principal amount of our 2016 Notes.

75

Reorganization Items, Net. The reorganization items recorded during the three months and nine months ended September 30, 2016 related to expenses in connection with our Chapter 11 Cases. Refer to Note 3. "Reorganization Items, Net" to the accompanying unaudited condensed consolidated financial statements for further information regarding our reorganization items.

Results from continuing operations, net of income taxes, improved for the three and nine months ended September 30, 2016 compared to the same periods in the prior year primarily due to lower pretax losses and the related tax impacts.

Income Tax Benefit. The income tax benefit recorded during the three months ended September 30, 2016 increased compared to the same period in the prior year primarily due to pretax losses in the current year as compared to pretax income during the prior year. The income tax benefit recorded during the nine months ended September 30, 2016 increased compared to the same period in the prior year due to the tax allocation to continuing operations related to the tax effects of items credited to "Other comprehensive income" and the benefit of a loss carry back refund recorded in the current year, partially offset by the tax impact of impairment charges recognized during the 2015 period. Refer to Note 12. "Income Taxes" in the accompanying unaudited condensed consolidated financial statements for additional information.

Net loss attributable to common stockholders improved for the three and nine months ended September 30, 2016 compared to the same periods in the prior year, which reflected the trend in results from continuing operations for each period, in addition to the favorable impact of results from discontinued operations.

76

Loss from Discontinued Operations, Net of Income Taxes. The favorable change in results from discontinued operations for the three and nine months ended September 30, 2016 compared to the same periods in the prior year was driven primarily by Patriot bankruptcy related charges associated with black lung liabilities and the UMWA Combined Benefit Fund totaling $155.1 million recognized in the third quarter of 2015 as compared to a charge of $35.0 million recorded in the current period for the UMWA 1974 Pension Plan. Results for the nine month period also included a contingent loss accrual of $7.6 million recognized in the first quarter of 2015 associated with the Queensland Bulk Handling Pty Ltd. litigation. Those matters are discussed further in Note 19. "Commitments and Contingencies" and Note 20. "Matters Related to the Bankruptcy of Patriot Coal Corporation", respectively, to the accompanying unaudited condensed consolidated financial statements.

Outlook

Our near-term outlook is intended to coincide with the next 12 to 24 months, with subsequent periods addressed in our long-term outlook.

Near-Term Outlook

Coal industry fundamentals have shown signs of improvement with both seaborne metallurgical and thermal pricing reaching multi-year highs in recent months and domestic U.S. coal consumption improving in the past quarter. Newcastle index thermal coal spot pricing in October was the highest since early 2013 while high quality hard coking coal settlement pricing was the highest since 2012. Price increases have been driven by lower domestic China production leading to increased coal imports and supply interruption in Australia. U.S. domestic electricity generation increased as a result of above-average cooling degree days, which along with increasing natural gas prices since March, positively impacted utility coal consumption and resulted in stockpile drawdowns. U.S. coal prices have strengthened with prompt PRB 8,800 Btu/Lb coal prices reaching $11.87 per ton as of October 31, 2016, up 15% year-to-date.

Global Macroeconomic Indicators. The International Monetary Fund (IMF) released its updated global economic growth estimates in its October 2016 World Economic Outlook. The IMF's outlook for global growth in 2016 is 3.1%, which is slightly below the prior IMF forecast of 3.2% and roughly in line with global growth of 3.2% in 2015. The IMF projects global growth of 3.4% in 2017.

77

Selected regional and worldwide projections of 2016 and 2017 macroeconomic growth, as measured by recent IMF forecasts of gross domestic product (GDP), are presented below.

	GDP Growth (%)
Region:	2016		2017
U.S.	1.6	%	2.2	%
China	6.6	%	6.2	%
India	7.6	%	7.6	%
Worldwide	3.1	%	3.4	%

Seaborne Thermal Coal. Seaborne thermal coal demand has improved in recent months largely driven by increased coal imports into China. As a result, Newcastle index thermal coal spot prices have risen to $108.60 per tonne as of October 31, 2016, up $58.00 per tonne (+115%) year-to-date, their highest levels since early 2013. Higher China import demand is primarily the result of stronger electricity generation, improved industrial demand and reduced domestic coal supply largely driven by restrictive policies. Seaborne demand growth outside of China has been relatively weak, as evidenced by reduced imports into India.

Following the strong surge in prices, China has relaxed production restrictions multiple times. In addition, current price levels may incentivize exporting producers to consider increasing production and export supply. A key driver for future seaborne thermal coal supply and demand balance is the outlook for China import demand, which remains uncertain and is expected to be dependent in part on the sustainability and enforcement of China’s domestic production policy.

Seaborne Metallurgical Coal. Supply tightness and increased seaborne import demand have resulted in sharply higher seaborne high quality hard coking coal prices in recent months. Domestic supply declines in China accelerated during the quarter largely due to policy restrictions, which along with reduced coal supplies from Australia and other key exporting countries drove spot prices to $260 per tonne as of October 31, 2016, a 240% year-to-date increase and the highest level since September 2011. Seaborne metallurgical coal prices for high quality hard coking coal and low-vol PCI settled at $200 and $133 per tonne, respectively, for quarterly contracts commencing in October 2016, increasing 116% and 77% percent, respectively, versus prior-quarter price levels.

Similar to thermal, China’s domestic metallurgical coal production is expected to recover due to relaxed policy on production curtailments, leading to the potential for reduced coal imports.

U.S. Thermal Coal. Favorable weather, stronger than expected year-to-date coal consumption and increasing natural gas prices since March have improved the outlook for coal demand in 2016 and 2017. Peabody now projects U.S. utility coal consumption to decline approximately 50 to 65 million tons in 2016 versus 2015. Peabody estimates total 2016 U.S. coal industry shipments to decline 150 to 165 million tons, driving utility stockpiles lower. We expect U.S. thermal coal supply and demand to rebalance in 2017 as natural gas prices increase, coal consumption grows, exports stabilize and stockpile drawdowns continue.

Regulatory Update

Other than as described in the following section, there were no significant changes to our regulatory matters subsequent to December 31, 2015. Information regarding our regulatory matters is outlined in Part I, Item 1. "Business" in our Annual Report on Form 10-K for the year ended December 31, 2015.

Regulatory Matters - U.S.

SEC Proposed Rules to Modernize Property Disclosures for Mining Registrants. On June 16, 2016, the SEC announced proposed rules designed to modernize the disclosure requirements for mining properties. The proposed rules would, among other things, (i) provide a standard requiring an issuer to disclose mining operations that are material to its business or financial condition, (ii) require a reporting company to disclose mineral resources and material exploration results in addition to mineral reserves, (iii) permit disclosure of mineral reserves based on a preliminary or final feasibility study, (iv) require disclosures of mining operations as a whole, as well as disclosure for material individual properties, (v) require that an issuer’s disclosure for mineral resources, mineral reserves and material exploration results be based on supporting documentation prepared by a qualified person (as defined in the proposed rule) and (vi) require that qualified person to issue a technical report summary. The comment period on the proposed rules is now closed. We are evaluating the impact of compliance with these rules.

New Source Performance Standards for Carbon Dioxide Emissions From New, Modified and Reconstructed Fossil Fuel-Fired Electricity Utility Generating Units (EGUs). The EPA released the final rule regarding emissions of carbon dioxide (CO2) from new, modified and reconstructed fossil fuel-fired EGUs on August 3, 2015, and published the rule in the Federal Register on October 23, 2015. Numerous legal challenges to the final rule have been filed in the D.C. Circuit. Sixteen separate petitions for review were filed, and the challengers include 25 states, utilities, mining companies (including Peabody), labor unions, trade organizations and other groups. The cases have been consolidated under the case filed by North Dakota. Four additional cases were filed seeking review of the EPA’s denial of reconsideration petitions in a final action published in the May 6, 2016 Federal Register entitled “Reconsideration of Standards of Performance for Greenhouse Gas Emissions From New, Modified, and Reconstructed Stationary Sources: Electric Generating Units; Notice of final action denying petitions for reconsideration.” States and other organizations have intervened on behalf of the EPA. Upon petitioners’ request, the D.C. Circuit suspended the briefing schedule and consolidated the challenges to the EPA’s denial of petitions for reconsideration with the previously filed North Dakota case. On August 30, 2016, the Court entered a briefing schedule under which final briefs will be due February 6, 2017.

Rules for Regulating Carbon Dioxide Emissions From Existing Fossil Fuel-Fired EGUs. On August 3, 2015, the EPA announced the final rule regarding regulation of CO2 emissions from existing fossil fuel-fired EGUs, and published the rule in the Federal Register on October 23, 2015. In the final rule, the EPA established emission guidelines for states to use in developing plans to reduce CO2 emissions from existing fossil fuel-fired EGUs. Following Federal Register publication of the final rule on October 23, 2015, 39 separate petitions for review by approximately 157 entities were filed in the D.C. Circuit. The petitioners include 27 states and governmental entities, utilities, industry groups, trade associations, coal companies, and other entities. The petitions were consolidated by the D.C. Circuit with the case filed by West Virginia and Texas (in which other states have also joined). On October 29, 2015, we filed a motion to intervene in the case filed by West Virginia and Texas, in support of the petitioning states. The motion was granted on January 11, 2016. Numerous states and cities have also been allowed to intervene in support of the EPA.

On February 9, 2016, the Supreme Court granted a stay of the rule pending disposition of the petitions for review in the D.C. Circuit and disposition of the applicants’ petition for a writ of certiorari, if such writ is sought. The stay provides that, if a writ of certiorari is sought and the Supreme Court denies the petition, the stay will terminate automatically. The stay also provides that, if the Supreme Court grants the petition for a writ of certiorari, the stay will terminate when the Supreme Court enters its judgment. Briefing on the merits of the petitions for review in the D.C. Circuit has concluded. The case was heard en banc by ten active D.C. Circuit judges on September 27, 2016.

Cross State Air Pollution Rule (CSAPR). On July 6, 2011, the EPA finalized the CSAPR, which required the District of Columbia and 27 states from Texas eastward (not including the New England states or Delaware) to significantly improve air quality by reducing power plant emissions that cross state lines and contribute to ozone and/or fine particle pollution in other states. Under the CSAPR, the first phase of the nitrogen oxide and sulfur dioxide emissions reductions was to commence in 2012 with further reductions effective in 2014. In October 2011, the EPA proposed amendments to the CSAPR to increase emission budgets in ten states, including Texas, and ease limits on market-based compliance options. While the CSAPR had an initial compliance deadline of January 1, 2012, the rule was challenged and, on December 30, 2011, the D.C. Circuit stayed the rule and advised that the EPA was expected to continue administering the Clean Air Interstate Rule until the pending challenges are resolved. The court vacated the CSAPR on August 21, 2012, in a two-to-one decision, concluding that the rule was beyond the EPA's statutory authority. However, the U.S. Supreme Court on April 29, 2014 reversed the D.C. Circuit and upheld the CSAPR, concluding generally that the EPA’s development and promulgation of CSAPR was lawful, while acknowledging the possibility that under certain circumstances some states may have a basis to bring a particularized, as-applied challenge to the rule. In October 2014, the D.C. Circuit filed an order lifting its stay of CSAPR and addressing a number of preliminary motions regarding the implementation of the Supreme Court’s remand. EPA subsequently promulgated a rule to require that CSAPR emission reductions be achieved in 2015 and 2017.

On remand, the D.C. Circuit court also held on July 28, 2015 that certain of EPA’s Phase II emission budgets were invalid because they required more emissions reductions than necessary to achieve the desired air pollutant reduction in the relevant downwind states. The court did not vacate the rule but required the EPA to reconsider the invalid emissions budgets as to those states. On November 16, 2015, the EPA proposed amendments to the Cross State Air Pollution Rule (CSAPR). EPA indicated that this rule was a “partial response” to the D.C. Circuit’s remand. This rule, known as the CSAPR Update Rule, was signed by the EPA Administrator on September 7, 2016. EPA states that the rule is intended to address implementation of the 2008 ozone national air quality standards as well as part of the remand by the D.C. Circuit. The final rule implements further reductions in nitrogen oxides in 2017 in 22 states subject to CSAPR during the summertime ozone season. EPA did not address other aspects of the remand involving the CSAPR budgets for sulfur dioxide in four states.

Mercury and Air Toxic Standards (MATS). On April 14, 2016, the United States Environmental Protection Agency (EPA) issued a final supplemental finding in response to the U.S. Supreme Court’s decision that the EPA interpreted the Clean Air Act unreasonably when it deemed cost irrelevant to the decision to regulate power plants, concluding that it is appropriate and necessary to set standards for emissions of air toxics (including mercury) from coal- and oil-fired power plants. Environmental and industry groups challenged that supplemental finding in the United States Court of Appeals for the D.C. Circuit (D.C. Circuit) in three separate petitions for review, which were subsequently consolidated. Briefing is set to commence in November 2016 and conclude in March 2017.

Stream Protection Rule. On July 27, 2015, the Office of Surface Mining Reclamation and Enforcement (OSM) issued its proposed Stream Protection Rule (SPR). The proposed rule would amend over 475 existing rules and add new requirements, impact both surface and underground mining operations, and would, among other changes, increase testing and monitoring requirements related to the quality or quantity of surface water and groundwater or the biological condition of streams. The final rule was sent to the Office of Information and Regulatory Affairs at the Office of Management and Budget for review in late May 2016, but has not been issued. It is not clear when the rule will be finalized.

Office of Surface Mining Reclamation and Enforcement Self-Bonding Notice of Rulemaking. On August 16, 2016, the Office of Surface Mining Reclamation and Enforcement (“OSMRE”) announced a decision to initiate a rulemaking to update OSMRE’s bonding regulations. The decision stated that the OSMRE will be reviewing the self-bonding program and will consider revising the review process for determining if a company qualifies for self-bonding as well as the process for replacing self-bonds in the event a company no longer qualifies for self-bonding. There is no anticipated timing for the proposed rule.

Regulatory Matters - Australia

Mining Tenements and Environmental.  On April 22, 2016, the Queensland State government passed amendments to the Environmental Protection Act 1994 (EP Act) which grant new powers to compel certain “related persons” to satisfy the environmental obligations of companies experiencing financial difficulty who are operating in Queensland. A statutory guideline which must be followed by the Queensland Department of Environment and Heritage Protection to a “related person” is under development in consultation with stakeholders including those in the mining industry. The guideline is expected to be completed in November 2016.

Mining Tenements and Environmental. In Queensland, laws and regulations related to mining include, but are not limited to, the Mineral Resources Act 1989, Environmental Protection Act 1994 (EP Act), Environmental Protection Regulation 1998, Sustainable Planning Act 2009, Building Act 1975, Explosives Act 1999, Aboriginal Cultural Heritage Act 2003, Water Act 2000, State Development and Public Works Organisation Act 1971, Queensland Heritage Act 1992, Transport Infrastructure Act 1994, Nature Conservation Act 1992, Vegetation Management Act 1999, Land Protection (Pest and Stock Route Management) Act 2002, Land Act 1994, Regional Planning Interests Act 2014, Fisheries Act 1994 and Forestry Act 1959. Following extensive industry consultation over several years, the Mineral Resources Act 1989 was amended effective September 27, 2016. The amendment modifies to the existing framework with respect to the management of overlapping coal and coal seam gas resource authorities including the requirement for coal mining proponents to provide advance notice to gas proponents prior to the conduct of activities. These notice periods can be truncated subject to compensating the gas proponent for the loss of gas production due to the acceleration of activities. The requirement for applicants for production tenure to reach agreement with overlapping existing production tenure holders prior to grant has been removed. The new regime will apply to overlapping exploration tenure; however, it will not (except with respect to certain new safety requirements) apply to existing production tenements unless proponents agree to opt-in to the new regime. Transitional provisions apply with respect to production tenement applications.

Occupational Health and Safety.  State legislation requires us to provide and maintain a safe workplace by providing safe systems of work, safety equipment and appropriate information, instruction, training and supervision. In recognition of the specialized nature of mining and mining activities, specific occupational health and safety obligations have been mandated under state legislation specific to the coal mining industry. There are some differences in the application and detail of the laws, and mining operators, directors, officers and certain other employees are all subject to the obligations under this legislation.

In light of the recent discovery of a number of cases of pneumoconiosis in current and former coal mine workers in Queensland, the Department of Natural Resources recently commissioned a review of the current coal mine workers’ health assessment process to ensure it is effective in the early detection of respirable lung diseases such as pneumoconiosis. A Parliamentary enquiry committee has also been established to inquire into the re-emergence of the disease and is due to report on the matter in April 2017.

Long-Term Outlook

There were no significant changes to our Long-term Outlook during the quarter ended September 30, 2016 from the Long-term Outlook outlined in Part I. Item 2. "Management’s Discussion and Analysis of Financial Condition and Results of Operations" of our Quarterly Report on Form 10-Q for the quarter ended June 30, 2016.

Liquidity and Capital Resources

Overview

Our primary sources of cash are proceeds from the sale of our coal production to customers. We have also generated cash from the sale of non-strategic assets, including coal reserves and surface lands. Our primary uses of cash include the cash costs of coal production, capital expenditures, coal reserve lease and royalty payments, capital and operating lease payments, postretirement plans, take-or-pay obligations and post-mining retirement obligations. Historically, we have also generated cash from borrowings under our credit facilities and, from time to time, the issuance of securities. We have also historically utilized cash to service debt costs (including interest and principal).

Total Indebtedness. Our total indebtedness as of September 30, 2016 and December 31, 2015 consisted of the following:

	September 30, 2016		December 31, 2015

Liquidity After Filing Under Chapter 11 of the United States Bankruptcy Code

As of September 30, 2016, our available liquidity was $1,167.8 million which was substantially comprised of cash and cash equivalents. During the first quarter of 2016, we borrowed $947.0 million under the $1.65 billion revolving credit facility (as amended, the 2013 Revolver) for general corporate purposes. In accordance with our DIP Credit Agreement, we are required to maintain certain minimum liquidity thresholds. Of the $1,167.8 million of liquidity, $702.1 million was held by Debtor entities. Peabody is limited in its ability to transfer funds between Debtor and non-debtor entities or between certain non-debtor entities by court order, and, in certain instances, Peabody must first seek the approval of the DIP Lenders and the Bankruptcy Court to make such transfers. As of the Petition Date, we had approximately $675 million letters of credit outstanding under the 2013 Revolver. Subsequent to the Petition Date, certain counterparties drew on a portion of those letters of credit.  The letters of credit were in place to support various types of obligations, though the most significant items related to bank guarantees in place for reclamation obligations in Australia.  The draws required the recording of previously off-balance sheet liabilities, except in certain instances where we had previously recorded a liability, and as such have been reflected as additional borrowings under the 2013 Revolver.  The total of such letters of credit was $441.4 million during the three months ended September 30, 2016. "Investments and other assets" in the condensed consolidated balance sheets as of September 30, 2016 includes $343.7 million of collateral in support of certain of these obligations.

As a result of filing the Bankruptcy Petitions on April 13, 2016, we are in default under the 2013 Credit Facility (as defined below) and as such the 2013 Revolver can no longer be utilized.

Subject to certain exceptions under the Bankruptcy Code, the filing of the Bankruptcy Petitions automatically enjoined, or stayed, the continuation of any judicial or administrative proceedings or other actions against the Debtors or their property to recover, collect or secure a claim arising prior to the filing of the Bankruptcy Petitions. Thus, for example, most creditor actions to obtain possession of property from the Debtors, or to create, perfect or enforce any lien against the Debtors' property, or to collect on monies owed or otherwise exercise rights or remedies with respect to a prepetition claim are enjoined unless and until the Bankruptcy Court lifts the automatic stay.

The Bankruptcy Court has approved payment of certain prepetition obligations, including payments for employee wages, salaries and certain other benefits, customer programs, taxes, utilities and certain payments of insurance, essential suppliers, possessory lien vendors and surety bond issuers. Despite the liquidity provided by our existing cash on hand, cash from operations and the DIP Credit Agreement, our ability to maintain normal credit terms with our suppliers may become impaired. We have been and may continue to be required to pay cash in advance to certain vendors and may experience restrictions on the availability of trade credit, which would further reduce our liquidity. Our suppliers could refuse to provide key products and services if we are unable to reach an agreement on credit terms. In addition, due to the public perception of our financial condition and results of operations, in particular with regard to our potential failure to meet our debt obligations, some customers could be reluctant to enter into long-term agreements with us or may seek to terminate or modify their contracts with us.

We have incurred and expect to continue to incur significant costs associated with the Chapter 11 Cases and our reorganization, but we cannot accurately predict the effect the Chapter 11 Cases will have on our operations, liquidity, financial position and results of operations. We believe that our cash on hand, cash generated from the results of our operations, and borrowings under the DIP Credit Agreement will be sufficient to fund anticipated cash requirements through the Chapter 11 Cases for minimum operating and capital expenditures and for working capital purposes. However, given the current level of volatility in the market and the unpredictability of certain costs that could potentially arise in our mining operations, our liquidity needs could be significantly higher than we currently anticipate.

Our ability to maintain adequate liquidity through the reorganization process and beyond depends on our ability to successfully implement our plan of reorganization, successful operation of our business, and appropriate management of operating expenses and capital spending. Our anticipated liquidity needs are highly sensitive to changes in each of these and other factors. Refer to Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2015 and Part II, Item 1A. "Risk Factors" in our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2016 and June 30, 2016 for a discussion of the risks associated with our liquidity after the filing of our Chapter 11 Cases.

82

On the Petition Date, the Debtors also filed a motion (the DIP Motion) seeking authorization to use cash collateral and to approve financing (the DIP Financing) under that certain Superpriority Secured Debtor-In-Possession Credit Agreement (the DIP Credit Agreement) by and among Peabody as borrower, Peabody Global Funding, LLC, formally known as the Global Center for Energy and Human Development and certain Debtors party thereto as guarantors (the Guarantors and together with the Company, the Loan Parties), the lenders party thereto (the DIP Lenders) and Citibank, N.A. as Administrative Agent (in such capacity, the DIP Agent) and L/C Issuer. The DIP Credit Agreement provides for (i) a term loan not to exceed $500 million (the DIP Term Loan Facility), of which $200 million was made available upon entry of an interim order, the remaining $300 million pending the entry of the final order approving the DIP Credit Agreement (the Final Order), secured by substantially all of the assets of the Loan Parties, subject to certain excluded assets and carve outs and guaranteed by the Loan Parties (other than the Company), which would be used for working capital and general corporate purposes, to cash collateralize letters of credit and to pay fees and expenses, (ii) a cash collateralized letter of credit facility in an amount up to $100 million (the L/C Facility), and (iii) a bonding accommodation facility in an amount up to $200 million consisting of (x) a carve-out from the collateral with superpriority claim status, subject only to the fees carve-out, entitling the authority making any bonding request to receive proceeds of collateral first in priority before distribution to any DIP Lender or other prepetition secured creditor, except for letters of credit issued under the DIP Credit Agreement and/or (y) a letter of credit facility (the Bonding L/C Facility). The aggregate face amount of all letters of credit issued under the L/C Facility and the Bonding L/C Facility shall not at any time exceed $50 million without DIP Lender consent.

The DIP Credit Agreement includes covenants that, subject to certain exceptions, require Peabody to maintain certain minimum thresholds of liquidity and consolidated EBITDA and to not exceed a certain maximum capital spend, and limit the ability of Peabody and the Guarantors to, among other things: (i) make dispositions of material leases and contracts, (ii) make acquisitions, loans or investments, (iii) create liens on their property, (iv) dispose of assets, (v) incur indebtedness, (vi) merge or consolidate with third parties, (vii) enter into transactions with affiliated entities, and (viii) make material changes to their business activities.

In addition to customary events of default, the DIP Credit Agreement contains the following milestones relating to the Chapter 11 Cases certain of which milestones have been modified as reflected below pursuant to amendments to the DIP Credit Agreement entered into since the Petition Date, the failure of which, if not cured, amended or waived, would result in an event of default:

• not later than 120 days following the Petition Date, delivery of the U.S. Business Plan and the Australian Business Plan (such plans were delivered to and approved by the DIP Lenders on August 10, 2016);

• not later than the earlier to occur of (i) the date that is three business days following the entry of the Final Order and (ii) the date that is 45 days following the Petition Date, a declaratory judgment action shall be commenced by Peabody (without prejudice to the rights of any party-in-interest to commence such a declaratory judgment action or any other proceeding) seeking a determination of the Principal Property Cap (including the amount thereof) and which of the U.S. Mine complexes are Principal Properties (the CNTA Issues), and not later than November 23, 2016, the Bankruptcy Court shall have entered an order determining the CNTA Issues (the CNTA Order Date);

• not later than the later of (i) 30 days following the CNTA Order Date and (ii) December 14, 2016, the filing of an Acceptable Reorganization Plan (as defined below) and related disclosure statement;

• not later than January 31, 2017, entry of an order approving a disclosure statement for an Acceptable Reorganization Plan; and

• not later than 330 days following the Petition Date, the entry of an order confirming an Acceptable Reorganization Plan; not later than 360 days following the Petition Date, effectiveness of an Acceptable Reorganization Plan.

“Acceptable Reorganization Plan” means a reorganization plan that (i) provides for the termination of the commitments and the payment in full in cash of the obligations under the DIP Credit Agreement (other than contingent indemnification obligations for which no claims have been asserted) on the consummation date of such reorganization plan and (ii) provides for customary releases of the DIP Agent, the DIP Lenders and the L/C Issuer and each of their respective representatives, from any and all claims against the DIP Agent, the DIP Lenders and the DIP L/C Issuer in connection with the DIP Credit Agreement or the cases to the fullest extent permitted by the Bankruptcy Code and applicable law.

83

On April 15, 2016, the Bankruptcy Court issued an order approving the DIP Motion on an interim basis and authorizing the Loan Parties to, among other things, (i) enter into the DIP Credit Agreement and initially borrow up to $200 million, (ii) obtain a cash collateralized letter of credit facility in the aggregate amount of up to $100 million, and (iii) establish an accommodation facility for bonding requests in an aggregate stated amount of up to $200 million. On April 18, 2016, we entered into the DIP Credit Agreement with the DIP Lenders and borrowed $200 million under the DIP Term Loan Facility. On May 17, 2016, the Bankruptcy Court approved the DIP Financing on a final basis and entered an order to that effect on May 18, 2016. On May 19, 2016, following entry of the Final Order, we borrowed the remaining $300 million available under the DIP Term Loan Facility. The DIP Credit Agreement has been amended, as noted above and described in Note 1. "Basis of Presentation" and Note 13. "Current and Long-term Debt" to the accompanying unaudited condensed consolidated financial statements.

The scheduled maturity under the DIP Credit Agreement is the earliest of (a) the Scheduled Termination Date, (b) 45 days after the entry of the Interim Order if the Final Order has not been entered prior to the expiration of such 45-day period (as such period may be extended with the consent of certain DIP Lenders), (c) the substantial consummation of a plan of reorganization filed in the cases that is confirmed pursuant to an order entered by the Bankruptcy Court, (d) the acceleration of the loans and the termination of commitments with respect to the DIP Credit Agreement and (e) a sale of all or substantially all of the assets of Peabody (or the Loan Parties) pursuant to Section 363 of the Bankruptcy Code. Borrowings under the DIP Term Loan Facility bear interest at an interest rate per annum equal to, at Peabody's option (i) LIBOR plus 9.00%, subject to a 1.00% LIBOR floor or (ii) the base rate plus 8.00%.

“Scheduled Termination Date” means the date that is 12 months after the closing date; provided that such date may, at the election of Peabody, be extended by up to an additional 6 months so long as, at the time such extension shall become effective, (w) there shall exist no default under the DIP Credit Agreement, (x) the representations and warranties of the Loan Parties therein shall be true and correct in all material respects, (y) Peabody shall have paid or caused to be paid to the DIP Agent for the account of each DIP Lender an extension fee in an amount equal to 2.50% of such DIP Lender’s outstanding exposure under the DIP Term Loan Facility at such time and (z) Peabody shall have delivered to the DIP Agent an updated DIP budget covering the additional period to be effected by such extension.

We paid aggregate debt issuance costs of $25.6 million during the nine months ended September 30, 2016 related to the DIP Term Loan Facility, which will be amortized over a 12-month period.

Additionally, prior to the Petition Date, we made available to our Australian platform a committed $250 million revolving intercompany loan facility (Intercompany Loan Facility). The Intercompany Loan Facility is designed to provide additional liquidity to support the ongoing operations of the Australian business during the Chapter 11 Cases, with draw amounts being tied to operating budgets and subject to certain availability restrictions. In accordance with the terms of the DIP Credit Agreement, the aggregate outstanding principal amount shall not exceed $250 million at any one time, which amount shall be subject to increase by up to $200 million with the written consent of the DIP Lenders. The consent of the DIP Lenders is also required to grant liens valued at 50% or more of the assets collateralizing the Intercompany Loan Facility; however, as previously reported the DIP Lenders have expressly consented to an amendment or waiver of provisions in the Intercompany Loan Facility to permit asset sales of up to $250 million in cash proceeds in the aggregate over the life of the Intercompany Loan Facility. As of September 30, 2016, $30.0 million was outstanding on the Intercompany Loan Facility.

On March 25, 2016, we amended and restated our accounts receivable securitization program (securitization program) to, among other things, extend the term of the program by two years to March 23, 2018 and reduce the maximum availability under the facility from $275.0 million to $180.0 million. The accessible capacity of the program varies monthly, dependent upon the actual amount of receivables available for contribution and various reserves and limits. As of September 30, 2016, $22.8 million was deposited in a collateral account to secure letters of credit.

On April 12, 2016, we entered into an amendment to our securitization program to state that the filing of the Bankruptcy Petitions would not result in an automatic termination of the securitization program that would result in the acceleration of the obligations thereunder. On the Petition Date, the Debtors filed a motion seeking Bankruptcy Court approval of the continuation of the securitization program on the terms set forth in the amendments. On April 15, 2016, the Bankruptcy Court entered an order approving this motion on an interim basis. On April 18, 2016, we entered into an additional amendment to its securitization program to (i) change the maturity date to the earlier of March 23, 2018 and the emergence of the Debtors from the Chapter 11 Cases, (ii) revise the schedule of fees and (iii) enter into an additional performance guarantee by our subsidiaries that are contributors under the securitization facility promising to fulfill obligations of the other contributors. On May 17, 2016, the Bankruptcy Court approved the securitization program on a final basis and entered an order to that effect on May 18, 2016.

84

Contractual Obligations

Our Bankruptcy Petitions constituted an event of default under our derivative financial instrument contracts and the counterparties terminated the agreements shortly thereafter in accordance with contractual terms. The terminated positions are first-lien obligations secured by the collateral and all of the property that is subject to liens under our secured credit agreement dated September 24, 2013 (as amended, the 2013 Credit Facility). As a result of the terminations, we have recorded a settlement liability, without credit valuation adjustments, of $257.3 million. The net settlement liability will be accounted for as a prepetition liability subject to compromise.

Historical Cash Flows

The following table summarizes our cash flows for the nine months ended September 30,2016 and 2015, as reported in the accompanying unaudited condensed consolidated financial statements:

	Nine Months Ended						Increase (Decrease)
	September 30,						to Cash and Cash Equivalents
	2016			2015			$			%
	(Dollars in millions)
Net cash used in operating activities	$	(276.8	)	$	(90.6	)	$	(186.2	)	(206	)%
Net cash used in investing activities	(199.7		)	(146.3		)	(53.4		)	(37	)%
Net cash provided by in financing activities	1,383.0			273.2			1,109.8			406	%
Net change in cash and cash equivalents	906.5			36.3			870.2			2,397	%
Cash and cash equivalents at beginning of period	261.3			298.0			(36.7		)	(12	)%
Cash and cash equivalents at end of period	$	1,167.8		$	334.3		$	833.5		249	%

Operating Activities. The decrease in net cash provided by operating activities for the nine months ended September 30, 2016 compared to the same period in the prior year was driven by the following:

• A year-over-year decrease in cash from our mining operations;

• Funds that became restricted during the year as collateral for financial assurances associated with reclamation obligations ($94.8 million); and

• An unfavorable change in net cash flows associated with our working capital ($65.5 million, excluding the impact of payments to the voluntary employee beneficiary association (VEBA) discussed separately below) despite the utilization of the 30-day grace period with respect to a $21.1 million semi-annual interest payment due March 15, 2016 on the 6.50% Senior Notes due September 2020 and a $50.0 million semi-annual interest payment due March 15, 2016 on the 10.00% Senior Secured Second Lien Notes due March 2022; partially offset by

• Lower aggregate payments to Patriot and the related VEBA made in connection with our 2015 and 2016 settlement agreements with Patriot and the UMWA ($45.0 million).

85

Investing Activities. The unfavorable change in cash results from investing activities for the nine months ended September 30, 2016 compared to the same period in the prior year was mainly due to:

• Higher federal coal lease expenditures ($159.2 million) due to the timing of required payments in the third quarter of 2016 versus during the fourth quarter of 2015; and

• Lower net proceeds from debt and equity security investment transactions ($11.0 million) due primarily to the second quarter 2015 divestment of our prior holdings of Winsway Enterprises Holdings Limited marketable equity securities; partially offset by

• Higher proceeds from disposals of assets ($95.1 million) primarily due to the sale of our 5.06 percent participation interest in the Prairie State Energy Campus, as well as our interest in undeveloped metallurgical reserve tenements in Queensland's Bowen Basin, which included the Olive Downs South, Olive Downs South Extended and Willunga tenements; and

• Lower current year additions to property, plant, equipment and mine development ($29.4 million, net of changes in accrued expenses related to capital expenditures).

Financing Activities. The increase in net cash provided by financing activities for the nine months ended September 30, 2016 compared to the same period in the prior year was reflective of:

• Higher proceeds from long-term debt ($454.1 million), primarily due to the proceeds received from our DIP Term Loan Facility during the second quarter of 2016 ($475.0 million, net of original issue discount) and the net draws on our 2013 Revolver during the first quarter of 2016 ($947.0 million), partially offset by proceeds received from our Senior Secured Second Lien Notes ($975.7 million, net of original issue discount) during the first quarter of 2015; and

• Lower repayments of long-term debt ($654.7 million), mainly due to the extinguishment of $650.0 million aggregate principal of our 2016 Senior Notes in the first quarter of 2015.

Off-Balance Sheet Arrangements

In the normal course of business, we are a party to guarantees and financial instruments with off-balance-sheet risk, most of which are not reflected in the accompanying condensed consolidated balance sheets. We could experience a decline in our liquidity as financial assurances associated with reclamation obligations, bank guarantees, surety bonds or other obligations are required to be collateralized by cash or letters of credit.

Guarantees and Other Financial Instruments with Off-Balance Sheet Risk. See Note 18. "Financial Instruments and Other Guarantees" to our unaudited condensed consolidated financial statements for a discussion of our securitization program and guarantees and other financial instruments with off-balance sheet risk.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition, results of operations, liquidity and capital resources is based upon our financial statements, which have been prepared in accordance with GAAP. We are also required under 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. We evaluate our estimates on an ongoing basis. We base our estimates on historical experience and on various other assumptions that we believe 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.

Our critical accounting policies are discussed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2015. Our critical accounting policies remain unchanged at September 30, 2016.

Newly Adopted Accounting Standards and Accounting Standards Not Yet Implemented

See Note 2. "Newly Adopted Accounting Standards and Accounting Standards Not Yet Implemented" to our unaudited condensed consolidated financial statements for a discussion of newly adopted accounting standards.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Foreign Currency Risk

We have 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 8. "Derivatives and Fair Value Measurements" to the accompanying unaudited condensed consolidated financial statements. The Bankruptcy Petitions constituted an event of default under our derivative financial instrument contracts and the counterparties terminated the agreements shortly thereafter in accordance with contractual terms. As a result, we no longer have any foreign currency hedging instruments in place. Therefore, our exposure in operating costs and expenses due to a $0.05 change in the Australian dollar/U.S. dollar exchange rate is approximately $94 million for the next twelve months.

Other Non-Coal Trading Activities — Diesel Fuel Price Risk

Diesel Fuel and Explosives Hedges. We have historically managed price risk of the diesel fuel and explosives used in our mining activities through the use of cost pass-through contracts and from time to time, derivatives, primarily swaps. The Bankruptcy Petitions constituted an event of default under our derivative financial instrument contracts and the counterparties terminated the agreements shortly thereafter in accordance with contractual terms. As a result, we no longer have any diesel fuel derivative instruments in place.

We expect to consume 120 to 130 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 our annual diesel fuel costs by approximately $30 million based on our expected usage.

Item 4. Controls and Procedures.

Our 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 our principal executive and financial officers, on a timely basis. Our Chief Executive Officer and Chief Financial Officer have evaluated our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of September 30, 2016, and concluded that such controls and procedures are effective to provide reasonable assurance that the desired control objectives were achieved. Additionally, there have been no changes to our internal control over financial reporting during the most recent fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings.

See Note 1. "Basis of Presentation," Note 19. "Commitments and Contingencies" and Note 20. "Matters Related to the Bankruptcy of Patriot Coal Corporation" to the unaudited condensed consolidated financial statements included in Part I, Item 1. "Financial Statements" of this report relating to certain legal proceedings, which information is incorporated by reference herein.

Item 1A. Risk Factors.

For information regarding factors that could affect the Company's results of operations, financial condition and liquidity, see the risk factors discussed under in Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2015, filed with the SEC on March 16, 2016 and in Part II, Item 1A. "Risk Factors" in our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2016 and June 30, 2016, filed with the SEC on May 6, 2016 and August 8, 2016, respectively.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

Share Repurchase Programs

On October 24, 2008, we announced that our Board of Directors approved an amendment to the then existing share repurchase program to authorize repurchases of up to $1.0 billion of the then outstanding shares of our common stock (Repurchase Program). The Repurchase Program does not have an expiration date and may be discontinued at any time. Through September 30, 2016, we have repurchased a total of 0.5 million shares under the Repurchase Program at a cost of $299.6 million, leaving $700.4 million available for share repurchases under the Repurchase Program. Repurchases may be made from time to time based on an evaluation of our outlook and general business conditions, as well as alternative investment and debt repayment options. No share repurchases were made under the Repurchase Program during the nine months ended September 30, 2016 or 2015.

Share Relinquishments

We routinely allow employees to relinquish common stock to pay estimated taxes upon the vesting of equity awards and upon the issuance of common stock related to performance units under our equity incentive plans. The value of common stock tendered by employees is determined based on the closing price of our common stock on the dates of the respective relinquishments.

Purchases of Equity Securities

The following table summarizes all share purchases for the three months ended September 30, 2016:

Period	Total Number of Shares Purchased (1)	Average Price per Share		Total Number of Shares Purchased as Part of Publicly Announced Program	Maximum Dollar Value that May Yet Be Used to Repurchase Shares Under the Publicly Announced Program (In millions)
July 1 through July 31, 2016	188	$	2.76	—	$	700.4
August 1 through August 31, 2016	—	—		—	700.4
September 1 through September 30, 2016	—	—		—	700.4
Total	188	$	1.88	—

⁽¹⁾  Represents shares withheld to cover the withholding taxes upon the vesting of equity awards, which are not part of the Repurchase Program.

Item 4. Mine Safety Disclosures.

Our "Safety a Way of Life Management System" has been designed to set clear and consistent expectations for safety and health across our business. It aligns to the National Mining Association's CORESafety® framework and encompasses three fundamental areas: leadership and organization, safety and health risk management and assurance. We also partner with other companies and certain governmental agencies to pursue new technologies that have the potential to improve our safety performance and provide better safety protection for employees.

We continually monitor our safety performance and regulatory compliance. The information concerning mine safety violations or other regulatory matters required by SEC regulations is included in Exhibit 95 to this Quarterly Report on Form 10-Q.

Item 5. Other Information.

On November 3, 2016, Peabody Australia Mining Pty Ltd (the Seller), one of the Company’s Australian subsidiaries, entered into a definitive share sale and purchase agreement (the SPA) for the sale of all of the equity interests in Metropolitan Collieries Pty Ltd, the entity that owns Metropolitan coal mine in New South Wales, Australia (the Metropolitan Mine) and the associated 16.67 percent interest in the Port Kembla Coal Terminal, to South32 Aluminium (Holdings) Pty Ltd (the Buyer), a subsidiary of South32 Limited (South32), a global mining and metals company with operations in Australia, Southern Africa and South America. Pursuant to the SPA, the Buyer will acquire all of the equity interests in Metropolitan Collieries Pty Ltd in exchange for $200 million in cash, subject to a working capital adjustment (the Transaction). The Transaction also includes a contingent value right that enables the Company to share equally with South32 in any revenue above an agreed metallurgical coal price forward curve, after taxes, royalties and appropriate discounts, on all coal sold for the 12 months following completion of the Transaction, subject to extension if a minimum amount of coal is not sold in that period. The Transaction also is expected to release the Company from approximately A$20 million (approximately USD $15 million) in financial assurances, in the form of bank guarantees and cash, that will be replaced by South32.

The closing of the Transaction is currently anticipated to occur in the first quarter of 2017 and is conditional on receipt of approval from the Australian Competition and Consumer Commission (ACCC). A deposit has been paid by the Buyer by way of a bank guarantee, which can be drawn by the Seller in the event that ACCC approval is not obtained within a prescribed timeframe or the Buyer fails to complete the Transaction as required under the SPA. The SPA includes customary warranties, indemnities and undertakings, including an undertaking by each party to use all reasonable endeavors to procure the satisfaction of the closing conditions as soon as reasonably practicable after the date of the SPA. The Seller has also agreed, subject to certain exceptions, to conduct its affairs in the ordinary and usual course of business, consistent with past practice.

The SPA contains certain termination rights for the Seller and the Buyer. Among these rights, each of the Seller and the Buyer may cause the SPA to be terminated if (i) ACCC approval is not obtained on or before 120 days after the date of the Agreement, subject to an extension, or such other date as the parties may agree in writing, provided that the terminating party has complied in all material respects with its obligations under the relevant provision of the SPA, (ii) the other party or the other party’s guarantor becomes insolvent, (iii) a holder of a security interest takes possession of the whole or any substantial part of the undertaking and property of the other party or the other party’s guarantor, (iv) subject to a notice requirement, the other party fails to comply with certain of its obligations to be fulfilled on the closing date of the Transaction, or (v) the other party fails to comply with its obligation to use reasonable endeavors to obtain ACCC approval. In addition, the Buyer may terminate the SPA if a material adverse change occurs, as defined in the SPA.

Additionally, the Company determined that, as a result of entering into the Transaction, and the approval of the Company’s Board of Directors of such a transaction in October 2016, the mine was deemed to meet held-for-sale accounting criteria in the fourth quarter of 2016. Accordingly, the Company expects to record an after-tax impairment charge of approximately $180 million to write down the assets to their estimated selling price, which is the best estimate of fair value under a held-for-sale accounting model. The Company expects to report the impairment charge in its Annual Report on Form 10-K for the year ended December 31, 2016.

Exhibit 95

Mine Safety Disclosures

The following disclosures are provided pursuant to Securities and Exchange Commission (SEC) regulations, which require certain disclosures by companies required to file periodic reports under the Securities Exchange Act of 1934, as amended, that operate coal mines regulated under the Federal Mine Safety and Health Act of 1977 (the Mine Act). The disclosures reflect United States (U.S.) mining operations only, as these requirements do not apply to our mines operated outside the U.S. 

Mine Safety Information.  Whenever the Mine Safety and Health Administration (MSHA) believes that a violation of the Mine Act, any health or safety standard, or any regulation has occurred, it may issue a violation which describes the associated condition or practice and designates a timeframe within which the operator must abate the violation. In some situations, such as when MSHA believes that conditions pose a hazard to miners, MSHA may issue an order removing miners from the area of the mine affected by the condition until hazards are corrected. Whenever MSHA issues a citation or order, it generally proposes a civil penalty, or fine, as a result of the violation that the operator is ordered to pay. Citations and orders can be contested and appealed and, as part of that process, are often reduced in severity and amount, and are sometimes vacated. The number of citations, orders and proposed assessments vary depending on the size and type (underground or surface) of the company and mine. Since MSHA is a branch of the U.S. Department of Labor, its jurisdiction applies only to our U.S. mines. As such, the mine safety disclosures that follow contain no information for our Australian mines.

The tables that follow reflect citations and orders issued to us by MSHA during the three and nine months ended September 30, 2016, as reflected in our systems. The tables include only those mines that were issued orders or citations during the period presented and, commensurate with SEC regulations, does not reflect orders or citations issued to independent contractors working at our mines. Due to timing and other factors, our data may not agree with the mine data retrieval system maintained by MSHA. The proposed assessments for the three and nine months ended September 30, 2016 were taken from the MSHA system as of November 1, 2016.

Additional information about MSHA references used in the table is as follows:

• Section 104 S&S Violations: The total number of violations received from MSHA under section 104(a) of the Mine Act that could significantly and substantially contribute to a serious injury if left unabated.

• Section 104(b)Orders: The total number of orders issued by MSHA under section 104(b) of the Mine Act, which represents a failure to abate a citation under section 104(a) within the period of time prescribed by MSHA. This results in an order of immediate withdrawal from the area of the mine affected by the condition until MSHA determines that the violation has been abated.

• Section 104(d) Citations and Orders: The total number of citations and orders issued by MSHA under section 104(d) of the Mine Act for unwarrantable failure to comply with mandatory health or safety standards.

• Section 104(e) Notices: The total number of notices issued by MSHA under section 104(e) of the Mine Act for a pattern of violations that could contribute to mine health or safety hazards.

• Section 110(b)(2)Violations: The total number of flagrant violations issued by MSHA under section 110(b)(2) of the Mine Act.

• Section 107(a) Orders: The total number of orders issued by MSHA under section 107(a) of the Mine Act for situations in which MSHA determined an imminent danger existed.

• Proposed MSHA Assessments: The total dollar value of proposed assessments from MSHA.

• Fatalities: The total number of mining-related fatalities.

⁽¹⁾  The definition of "mine" under section 3 of the Mine Act includes the mine, as well as other items used in, or to be used in, or resulting from, the work of extracting coal, such as land, structures, facilities, equipment, machines, tools and coal preparation facilities. Also, there are instances where the mine name per the MSHA system differs from the mine name utilized by us. Where applicable, we have parenthetically listed the name of the mine per the MSHA system. Also, all mines are listed alphabetically within each of our U.S. mining segments.

Pending Legal Actions. The Federal Mine Safety and Health Review Commission (the Commission) is an independent adjudicative agency that provides administrative trial and appellate review of legal disputes arising under the Mine Act. These cases may involve, among other questions, challenges by operators to citations, orders and penalties they have received from MSHA, or complaints of discrimination by miners under section 105 of the Mine Act. The following is a brief description of the types of legal actions that may be brought before the Commission.

• Contests of Citations and Orders: A contest proceeding may be filed with the Commission by operators, miners or miners’ representatives to challenge the issuance of a citation or order issued by MSHA, including citations related to disputed provisions of operators' emergency response plans.

• Contests of Proposed Penalties (Petitions for Assessment of Penalties):A contest of a proposed penalty is an administrative proceeding before the Commission challenging a civil penalty that MSHA has proposed for the violation. Such proceedings may also involve appeals of judges' decisions or orders to the Commission on proposed penalties, including petitions for discretionary review and review by the Commission on its own motion.

• Complaints for Compensation:A complaint for compensation may be filed with the Commission by miners entitled to compensation when a mine is closed by certain withdrawal orders issued by MSHA. The purpose of the proceeding is to determine the amount of compensation, if any, due miners idled by the orders.

• Complaints of Discharge, Discrimination or Interference:A discrimination proceeding is a case that involves a miner’s allegation that he or she has suffered a wrong by the operator because he or she engaged in some type of activity protected under the Mine Act, such as making a safety complaint. This category includes temporary reinstatement proceedings, which involve cases in which a miner has filed a complaint with MSHA stating he or she has suffered discrimination and the miner has lost his or her position.

• Applications for Temporary Relief: An application for temporary relief from any modification or termination of any order or from any order issued under certain subparts of section 104 of the Mine Act may be filed with the Commission at any time before such order becomes final.

The table that follows presents information by mine regarding pending legal actions before the Commission at September 30, 2016. Each legal action is assigned a docket number by the Commission and may have as its subject matter one or more citations, orders, penalties or complaints.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The condensed consolidated financial statements include the accounts of Peabody Energy Corporation and its affiliates (the Company or Peabody). Interests in subsidiaries controlled by the Company are consolidated with any outside shareholder interests reflected as noncontrolling interests, except when the Company has an undivided interest in an unincorporated 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. As discussed below in Note 2. "Newly Adopted Accounting Standards and Accounting Standards Not Yet Implemented," prior year amounts of deferred financing costs have been reclassified to conform with the new standard.

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, 2015. 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, 2015 has been derived from the Company’s audited consolidated balance sheet at that date. The Company's results of operations for the three and nine months ended September 30, 2016 are not necessarily indicative of the results that may be expected for future quarters or for the year ending December 31, 2016.

Pursuant to the authorization provided at a special meeting of the Company's stockholders held on September 16, 2015, the Company completed a 1-for-15 reverse stock split of the shares of the Company’s common stock on September 30, 2015 (the Reverse Stock Split). As a result of the Reverse Stock Split, every 15 shares of issued and outstanding common stock were combined into one issued and outstanding share of Common Stock, without any change in the par value per share. No fractional shares were issued as a result of the Reverse Stock Split and any fractional shares that would otherwise have resulted from the Reverse Stock Split were paid in cash. The Reverse Stock Split reduced the number of shares of common stock outstanding from approximately 278 million shares to approximately 19 million shares. The number of authorized shares of common stock was also decreased from 800 million shares to 53.3 million shares. The Company's common stock began trading on a reverse stock split-adjusted basis on the New York Stock Exchange (NYSE) on October 1, 2015. All share and per share data included in this report has been retroactively restated to reflect the Reverse Stock Split. Since the par value of the common stock remained at $0.01 per share, the value for "Common stock" recorded to the Company's condensed consolidated balance sheets has been retroactively reduced to reflect the par value of restated outstanding shares, with a corresponding increase to "Additional paid-in capital."

The Company has classified items within discontinued operations in the unaudited condensed consolidated financial statements for disposals (by sale or otherwise) that have occurred prior to January 1, 2015 when the operations and cash flows of a disposed component of the Company were eliminated from the ongoing operations of the Company as a result of the disposal and the Company no longer had any significant continuing involvement in the operation of that component.

Filing Under Chapter 11 of the United States Bankruptcy Code

On April 13, 2016 (the Petition Date), Peabody and a majority of its wholly owned domestic subsidiaries as well as one international subsidiary in Gibraltar (the Filing Subsidiaries, and together with Peabody, the Debtors) filed voluntary petitions for reorganization (the petitions collectively, the Bankruptcy Petitions) under Chapter 11 of Title 11 of the U.S. Code (the Bankruptcy Code) in the United States Bankruptcy Court for the Eastern District of Missouri (the Bankruptcy Court). The Company’s Australian operations and other international subsidiaries are not included in the filings. The Debtors' Chapter 11 cases (collectively, the Chapter 11 Cases) are being jointly administered under the caption In re Peabody Energy Corporation, et al., Case No. 16-42529 (Bankr. E.D. Mo.). The Debtors continue to operate their businesses as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.

The filings of the Bankruptcy Petitions constituted an event of default under the Company’s prepretition credit agreement as well as the indentures governing certain of the Company’s debt instruments, as further described in Note 13. "Current and Long-term Debt" to the condensed consolidated financial statements, and all unpaid principal and accrued and unpaid interest due thereunder became immediately due and payable. Any efforts to enforce such payment obligations are automatically stayed as a result of the Bankruptcy Petitions and the creditors' rights of enforcement are subject to the applicable provisions of the Bankruptcy Code.

Additionally, on the Petition Date, the NYSE determined that Peabody’s common stock was no longer suitable for listing pursuant to Section 8.02.01D of the NYSE’s Listed Company Manual, and trading in the Company’s common stock was suspended. The Company's common stock began trading on the OTC Pink Sheets marketplace under the symbol BTUUQ on April 14, 2016. Following the Petition Date, the NYSE formally de-listed the Company's common stock.

On April 14, 2016, the Bankruptcy Court approved several motions (First Day Motions), including motions (i) authorizing the Debtors to pay prepetition wages and benefits for its workforce (Employee Motion), in part, (ii) prohibiting utilities from discontinuing service and authorizing the Debtors to provide adequate assurance deposits, (iii) authorizing the Debtors to pay prepetition obligations to certain critical vendors on an interim basis (Critical Vendor Motion), (iv) authorizing the Debtors to maintain their existing cash management system on an interim basis (Cash Management Motion), (v)  authorizing certain Debtors to continue selling and contributing receivables and related rights pursuant to a securitization facility on an interim basis (Securitization Motion) and (vi) authorizing the Debtors to enter into an $800 million debtor-in-possession financing facility (DIP Credit Agreement) on an interim basis (DIP Motion).

Pursuant to Section 362 of the Bankruptcy Code, the filing of the Bankruptcy Petitions automatically stayed most actions against the Debtors, including actions to collect indebtedness incurred prior to the Petition Date or to exercise control over the Debtors’ property. Subject to certain exceptions under the Bankruptcy Code, the filing of the Debtors’ Chapter 11 Cases also automatically stayed the continuation of most legal proceedings, including certain of the third party litigation matters described in Note 19. "Commitments and Contingencies" and Note 20. "Matters Related to the Bankruptcy of Patriot Coal Corporation" of this report or the filing of other actions against or on behalf of the Debtors or their property to recover on, collect or secure a claim arising prior to the Petition Date or to exercise control over property of the Debtors’ bankruptcy estates, unless and until the Bankruptcy Court modifies or lifts the automatic stay as to any such claim. Notwithstanding the general application of the automatic stay described above, governmental authorities may determine to continue actions brought under their police and regulatory powers.

The U.S. Trustee for the Eastern District of Missouri filed a notice appointing an official committee of unsecured creditors (the Creditors' Committee) on April 29, 2016. The Creditors’ Committee represents all unsecured creditors of the Debtors and has a right to be heard on all matters that come before the Bankruptcy Court.

On May 17, 2016, the Bankruptcy Court approved various of the First Day Motions on a final basis, including the Employee Motion, Critical Vendor Motion, Cash Management Motion, Securitization Motion and DIP Motion.

On May 20, 2016, the Debtors filed a complaint and request for declaratory judgment, as required by the terms of the DIP Credit Agreement, against Citibank, N.A. (in its capacity as Administrative Agent under the Debtors' prepetition secured credit agreement), among others, regarding the extent of certain collateral and secured claims of certain prepetition creditors (the CNTA Adversary Proceeding).

On June 13, 2016, Citibank, N.A. filed an answer and counter-claim for declaratory judgment.  On June 14, 2016, two motions to intervene were filed, one from the Creditors' Committee and another from a group of creditors holding $1.65 billion in face value of the Company's Senior Notes (as indicated in their motion). The intervention motions were granted on July 7, 2016.

On June 15, 2016, the Bankruptcy Court approved several motions, including motions that (i)  established deadlines for the filing of certain proofs of claim, approved the form and manner of notice thereof, and (ii)  established a key employee retention program.

On September 16, 2016, the Debtors filed two omnibus objections to certain proofs of claim.

On September 8, 2016, the Debtors filed an objection to a claim asserted by the United Mine Workers of America 1974 Pension Plan and Trust (UMWA Plan). On September 26, 2016, the UMWA Plan filed a motion for relief from the automatic stay, seeking to allow arbitration between the Debtors and the UMWA Plan to resume outside of the Bankruptcy Court's jurisdiction. On October 7, 2016, the UMWA Plan filed a motion to continue the hearing on the Debtors' objection to the UMWA Plan's proof of claim until January 2017.

On September 30, 2016, numerous professionals retained by the Debtors and the Creditors’ Committee filed their first interim fee applications.

On October 4, 2016, the Debtors filed several motions, including: (i) an application to retain additional professionals, (ii) a motion to reject certain contracts, (iii) a motion seeking authority for the Debtors to implement procedures by which the Debtors may, from time to time, amend and assume, or settle and buy-out, certain leases of personal property and equipment without need for further Bankruptcy Court approval (Equipment Lease Procedures Motion), and (iv) two motions related to the Debtors' insurance programs.

On October 11, 2016, the Bankruptcy Court approved a stipulation and agreed order filed by the Debtors seeking the authority to enter into that certain Amendment No. 4 and Consent Under Superpriority Secured Debtor-in-Possession Credit Agreement (the DIP Amendment). The DIP Amendment modifies certain of the milestones under the DIP Credit Agreement, including (i) a modification to the deadline by which the Bankruptcy Court shall enter an order determining the issues being adjudicated in the CNTA Adversary Proceeding (the CNTA Order) to provide that the Bankruptcy Court shall have entered the CNTA Order by no later than November 23, 2016; (ii) a modification to the deadlines for the Company to file an Acceptable Reorganization Plan (as defined in the DIP Credit Agreement) and related disclosure statement to provide that the Company must file these by, or on, the date that is the later of (a) 30 days after the entry of the CNTA Order and (b) December 14, 2016; and (iii) a modification to the deadline by which the Bankruptcy Court shall enter an order approving the Debtors' disclosure statement to provide that the Bankruptcy Court shall have entered this order by no later than January 31, 2017. The DIP Credit Agreement also contains restrictions on the ability of Peabody Global Funding, LLC (Global Funding) to amend or waive provisions under the Intercompany Loan Agreement (as defined in the DIP Credit Agreement) in a manner that would release or subordinate more than 50% of the collateral thereunder. The DIP Amendment modifies these restrictions to expressly allow Global Funding to amend or waive provisions under the Intercompany Loan Agreement to permit the release or subordination of collateral thereunder, including as a result of potential asset sales, of up to $250 million in cash proceeds in the aggregate over the life of the Intercompany Loan Agreement.

On October 14, 2016, the Debtors filed four omnibus objections to certain proofs of claim.

On October 18, 2016, the Bankruptcy Court granted several motions, including (i) an application to retain additional professionals, (ii) a motion to reject a certain contract, (iii) the Equipment Lease Procedures Motion, and (iv) two motions related to the Debtors' insurance programs authorizing the Debtors to (a) enter into a new postpetition property policy with an affiliate(s) of American International Group, Inc. and (b) assume certain existing policies and enter into a new workers compensation insurance policy with ACE American Insurance Company, including its affiliated companies. Additionally, the Bankruptcy Court partially and conditionally granted the motion for relief from the automatic stay filed on September 26, 2016 by the UMWA Plan. The Bankruptcy Court lifted the automatic stay to provide the UMWA Plan until October 28, 2016, to receive a written confirmation from the American Arbitration Association (the AAA) that the AAA could find an arbitrator with sufficient experience who could arbitrate the UMWA Plan's claim and reach a decision, without extension or any exception for cause, by January 26, 2017.

On October 21, 2016, Berenergy Corporation filed a motion to lift the automatic stay to allow it to appeal a final judgment entered in the Sixth Judicial District Court in the state of Wyoming, as discussed in more detail below in Note 19 "Commitments and Contingencies".

On October 24, 2016, the Debtors filed a motion to assume or reject non-residential leases to which the Debtors are a party.

On October 25, 2016, the UMWA Plan filed a copy of its correspondence with the AAA and on October 26, 2016, the Bankruptcy Court issued an order lifting the automatic stay to allow arbitration of the claim to proceed. The parties have selected an arbitrator, and the arbitration hearings are scheduled to begin on December 19, 2016.

On October 26, 2016, the Debtors filed a motion to assume certain executory contracts to which certain Debtors are a party, as well as an omnibus motion for the rejection of certain executory contracts regarding overriding royalties.

As a result of the Bankruptcy Petitions, the realization of the Debtors’ assets and the satisfaction of liabilities are subject to significant uncertainty. For the Debtors to emerge successfully from Chapter 11, they must obtain the Bankruptcy Court’s approval of a plan of reorganization, which will enable them to transition from Chapter 11 into ordinary course operations as reorganized entities outside of bankruptcy. A plan of reorganization determines the rights and treatment of claims of various creditors and equity security holders, and is subject to the ultimate outcome of negotiations and Bankruptcy Court decisions ongoing through the date on which the plan of reorganization is confirmed.

The Debtors intend to propose a plan of reorganization on or prior to the applicable date required under the Bankruptcy Code and in accordance with milestones set forth in the DIP Credit Agreement (as set forth below in Note 13. "Current and Long-term Debt"), as the same may be extended with approval of the Bankruptcy Court. As noted above, the Debtors and the parties to the DIP Credit Agreement entered into the DIP Amendment, which modified certain milestone dates. The Debtors presently expect that any proposed plan of reorganization will provide, among other things, for mechanisms for the settlement of claims against the Debtors’ estates, treatment of the Debtors' existing equity and debt holders, and certain corporate governance and administrative matters pertaining to the reorganized Debtors. A proposed plan of reorganization filed with the Bankruptcy Court likely will incorporate provisions arising out of the Debtors' discussions with their creditors and other interested parties, and likely will be further revised thereafter. There can be no assurance that the Debtors will be able to secure approval for their proposed plan of reorganization from the Bankruptcy Court or execute such plan. Further, a plan of reorganization is likely to materially change the amounts and classifications of assets and liabilities reported in the Company’s condensed consolidated financial statements. Although it is uncertain at this stage if any proposed plan of reorganization would allow for distributions with respect to equity or other securities, it is likely that equity securities will be cancelled and extinguished upon confirmation of a proposed plan of reorganization by the Bankruptcy Court, and that the holders thereof would not be entitled to receive, and would not receive or retain, any property or interest in property on account of such equity interests.

The Company believes it will require a significant restructuring of its balance sheet in order to continue as a going concern. The Company’s ability to continue as a going concern is dependent upon, among other things, its ability to become profitable and maintain profitability, its ability to access sufficient liquidity and its ability to successfully implement their Chapter 11 plan of reorganization. The accompanying condensed consolidated financial statements are prepared on a going concern basis and do not include any adjustments that might be required if the Company were unable to continue as a going concern.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Newly Adopted Accounting Standards and Accounting Standards Not Yet Implemented

Newly Adopted Accounting Standards and Accounting Standards Not Yet Implemented

Newly Adopted Accounting Standards

Going Concern. In August 2014, the Financial Accounting Standards Board (FASB) issued disclosure guidance that requires management to evaluate, at each annual and interim reporting period, whether substantial doubt exists about an entity's ability to continue as a going concern and, if applicable, to provide related disclosures. As outlined by that guidance, substantial doubt about an entity's ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that an entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued (or are available to be issued). The new guidance is effective for annual reporting periods ending after December 15, 2016 (the year ending December 31, 2016 for the Company) and interim periods thereafter, with early adoption permitted.

Deferred Financing Costs. On April 7, 2015, the FASB issued accounting guidance that requires deferred financing costs to be presented as a direct reduction from the related debt liability in the financial statements rather than as a separately recognized asset. Under the new guidance, amortization of such costs will continue to be reported as interest expense. In August 2015, an update was issued that clarified that debt issuance costs associated with line-of-credit arrangements may continue to be reported as an asset. The new guidance became effective retrospectively for interim and annual periods beginning after December 15, 2015 (January 1, 2016 for the Company). There was no material impact to the Company's results of operations or cash flows in connection with the adoption of the guidance.

The impact to the Company's condensed consolidated balance sheets as of December 31, 2015 was as follows:

	Before Application of Accounting Guidance		Adjustment			After Application of Accounting Guidance
	(Dollars in millions)
Other current assets	$	503.1	$	(55.5	)	$	447.6
Investments and other assets	382.6		(18.9		)	363.7
Total assets	11,021.3		(74.4		)	10,946.9
Current portion of long-term debt	5,930.4		(55.5		)	5,874.9
Long-term debt, less current portion	385.2		(18.9		)	366.3
Total liabilities	10,102.8		(74.4		)	10,028.4

Accounting Standards Not Yet Implemented

Revenue Recognition. In May 2014, the FASB issued a comprehensive revenue recognition standard that will supersede nearly all existing revenue recognition guidance under U.S. GAAP. The new standard provides a single principles-based, five-step model to be applied to all contracts with customers, which steps are to (1) identify the contract(s) with the customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when each performance obligation is satisfied. More specifically, revenue will be recognized when promised goods or services are transferred to the customer in an amount that reflects the consideration expected in exchange for those goods or services. The standard also requires entities to disclose sufficient qualitative and quantitative information to enable financial statement users to understand the nature, amount, timing and uncertainty of revenues and cash flows arising from contracts with customers.

Under the originally issued standard, the new guidance would have been effective for interim and annual periods beginning after December 15, 2016 (January 1, 2017 for the Company). On July 9, 2015, the FASB decided to delay the effective date of the new revenue recognition standard by one year with early adoption permitted, but not before the original effective date. The standard allows for either a full retrospective adoption or a modified retrospective adoption. The Company is in the process of evaluating the impact that the adoption of this guidance will have on its results of operations, financial condition, cash flows and financial statement presentation.

Inventory. In July 2015, the FASB issued guidance which requires entities to measure most inventory "at the lower of cost and net realizable value", thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market (market in this context is defined as one of three different measures, one of which is net realizable value). The guidance does not apply to inventories that are measured by using either the last-in, first-out method or the retail inventory method. The new guidance will be effective prospectively for annual periods beginning after December 15, 2016 (January 1, 2017 for the Company), and interim periods therein, with early adoption permitted. The Company is in the process of evaluating the impact that the adoption of this guidance will have on its results of operations, financial condition, cash flows and financial statement presentation.

Income Taxes. In November 2015, the FASB issued accounting guidance that requires entities to classify all deferred tax assets and liabilities, along with any related valuation allowance as noncurrent on the balance sheet. Under the new guidance, each jurisdiction will now only have one net noncurrent deferred tax asset or liability. The new guidance does not change the existing requirement that only permits offsetting within a jurisdiction. The new guidance will be effective prospectively or retrospectively for annual periods beginning after December 15, 2016 (January 1, 2017 for the Company) and interim periods therein, with early adoption permitted. While the Company does not anticipate an impact to its results of operations or cash flows in connection with the adoption of this guidance, there will be an impact on the presentation of the Company's condensed consolidated balance sheets. The impact to the condensed consolidated balance sheets will depend upon the facts and circumstances at the time of adoption.

Lease Accounting. In February 2016, the FASB issued accounting guidance that will require a lessee to recognize in its balance sheet a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term for leases with lease terms of more than 12 months.  Consistent with current U.S. GAAP, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. Additional qualitative disclosures along with specific quantitative disclosures will also be required.  The new guidance will take effect for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 (January 1, 2019 for the Company), with early adoption permitted.  Upon adoption, the Company will be required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company is in the process of evaluating the impact that the adoption of this guidance will have on its results of operations, financial condition, cash flows and financial statement presentation. 

Compensation - Stock Compensation. In March 2016, the FASB issued accounting guidance which identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. The new guidance will be effective prospectively for annual periods beginning after December 15, 2016 (January 1, 2017 for the Company) and interim periods therein, with early adoption permitted. The Company is in the process of evaluating the impact that the adoption of this guidance will have on its results of operations, financial condition, cash flows and financial statement presentation.

Financial Instruments - Credit Losses. In June 2016, the FASB issued accounting guidance related to the measurement of credit losses on financial instruments. The pronouncement replaces the incurred loss methodology to record credit losses with a methodology that reflects the expected credit losses for financial assets not accounted for at fair value with gains and losses recognized through net income. This standard is effective for fiscal years beginning after December 15, 2019 (January 1, 2020 for the Company) and interim periods therein,with early adoption permitted for fiscal years, and interim periods therein, beginning after December 15, 2018. The Company is in the process of evaluating the impact that the adoption of this guidance will have on its results of operations, financial condition, cash flows and financial statement presentation.

Classification of Certain Cash Receipts and Cash Payments. In August 2016, the FASB issued accounting guidance to amend the classification of certain cash receipts and cash payments in the statement of cash flows to reduce diversity in practice. The new guidance will be effective for fiscal years beginning after December 15, 2017 (January 1, 2018 for the Company) and interim periods therein, with early adoption permitted. The amendments in this update should be applied retrospectively to all periods presented, unless deemed impracticable, in which case, prospective application is permitted. The Company is currently evaluating this guidance and its impact on classification of certain cash receipts and cash payments in the Company's statements of cash flows.

Liabilities subject to compromise [Text Block]

Liabilities Subject to Compromise

Liabilities subject to compromise include unsecured or under-secured liabilities incurred prior to the Petition Date. These liabilities represent the amounts expected to be allowed on known or potential claims to be resolved through the Chapter 11 Cases and remain subject to future adjustments based on negotiated settlements with claimants, actions of the Bankruptcy Court, rejection of executory contracts, proofs of claims or other events. Additionally, liabilities subject to compromise also include certain items that may be assumed under a plan of reorganization, and as such, may be subsequently reclassified to liabilities not subject to compromise. Generally, actions to enforce or otherwise effect payment of prepetition liabilities are subject to the automatic stay, as discussed in Note 1. "Basis of Presentation".

Liabilities subject to compromise consisted of the following:

Asset Impairment (Notes)

Asset Impairment Charges [Abstract]

Asset Impairment Charges [Text Block]

Asset Impairment

The Company's mining and exploration assets and mining-related investments may be adversely affected by numerous uncertainties that may cause the Company to be unable to recover all or a portion of the carrying value of those assets. Because of the volatile and cyclical nature of U.S. and international seaborne coal demand, it is reasonably possible that prices may decrease in the near term, which, absent sufficient mitigation such as an offsetting reduction in the Company's operating costs, may result in the need for future adjustments to the carrying value of the Company's long-lived mining assets and mining-related investments.

The Company's assets whose recoverability and values are most sensitive to near-term pricing and other market factors include certain Australian metallurgical and thermal assets for which impairment charges were recorded in 2015 and certain U.S. coal properties being leased to unrelated mining companies under agreements that require royalties to be paid as the coal is mined. These assets had an aggregate carrying value of $577.7 million as of September 30, 2016. The Company conducted a review of those assets for recoverability as of September 30, 2016 and determined that no impairment charge was necessary as of that date.

As further discussed in Note 23. “Subsequent Event”, the Company has entered into an agreement for the sale of its Metropolitan mine. As a result of entering into the transaction, and the approval of the Company’s Board of Directors of such a transaction in October 2016, the Metropolitan mine was deemed to meet held-for-sale accounting criteria in the fourth quarter of 2016. Accordingly, the Company expects to record an after-tax impairment charge of approximately $180 million to write down the assets to their estimated selling price, which is the best estimate of fair value under a held-for-sale accounting model, in the fourth quarter of 2016. The carrying value of the mine is included in the value of assets noted as at-risk in the preceding paragraph.

Three and Nine Months EndedSeptember 30, 2016

The Company reviewed its portfolio of mining tenements and surface lands that were classified as held-for-sale. As a result of that review, the Company recognized an aggregate impairment charge of $17.2 million during the nine months ended September 30, 2016 to write down the carrying value of certain Australian metallurgical assets targeted for divestiture, and eventually divested, to their estimated fair value. For additional information regarding those divested assets, refer to Note 16. "Other Events".

Nine Months Ended September 30, 2015

The following costs are reflected in "Asset impairment" in the unaudited condensed consolidated statement of operations for the nine months ended September 30, 2015:

	Reportable Segment
	Australian Metallurgical Mining		Australian Thermal Mining		Corporate and Other		Consolidated
	(Dollars in millions)
Asset impairment charges:
Long-lived assets	$	527.0	$	8.2	$	182.2	$	717.4
Equity method investments	—		—		183.4		183.4
Total	$	527.0	$	8.2	$	365.6	$	900.8

Australian Metallurgical and Thermal Mining

Due to the severity of the decline in seaborne metallurgical and thermal coal pricing observed during the first half of 2015 and other adverse conditions noted during that period, the Company concluded that indicators of impairment existed surrounding its Australian mining platform as of June 30, 2015. Accordingly, the Company reviewed its Australian mining assets for recoverability and, based on that review, determined that the carrying values of three of its active mines that produce metallurgical coal were not recoverable and recognized an aggregate impairment charge of $230.5 million to write those assets down from their carrying value to their estimated fair value.

Also during the second quarter of 2015, the Company reviewed its portfolio of mining tenements and surface lands to identify non-strategic assets that could be monetized. In connection with that review, certain of such assets were deemed to meet held-for-sale accounting criteria or were otherwise considered more likely to generate cash flows through divestiture rather than development, with the long-term plans for certain adjacent assets also consequently affected. Accordingly, the Company recognized an aggregate impairment charge of $304.7 million to write down those assets from their carrying value to their estimated fair value.

In connection with a similar review of the Company's asset portfolio conducted during the second quarter of 2015 to identify non-strategic domestic assets that could be monetized, the Company identified non-strategic, non-coal-supplying assets as held-for-sale rather than held-for-use as of June 30, 2015. Accordingly, the Company recognized an impairment charge of $182.2 million to write the assets down from their carrying value to estimated fair value.

Equity Method Investments. Due to the impairment indicators noted above surrounding the Company's Australian platform, the Company reviewed its total investment in Middlemount Coal Pty Ltd. (Middlemount), which owns the Middlemount Mine in Queensland, Australia, as of June 30, 2015. As a result of that review, the Company determined that the carrying value of its total investment in Middlemount was other-than-temporarily impaired and recorded a charge of $46.6 million to write-off the equity investment and recorded a charge of $136.8 million to write down the carrying value of certain of its loans to Middlemount.

The fair value estimates made during the Company's impairment assessments were determined in accordance with the methods outlined in Note 1. "Summary of Significant Accounting Policies" to the consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015, except in certain instances where indicative bids were received related to non-strategic assets being marketed for divestiture. In those instances, the indicative bids were also considered in estimating fair value.

Derivatives and Fair Value Measurements

Risk Management — Non-Coal Trading Activities

The Company is exposed to several risks in the normal course of business, including (1) foreign currency exchange rate risk for non-U.S. dollar expenditures and balances, (2) price risk on coal produced by, and diesel fuel utilized in, the Company's mining operations and (3) interest rate risk that has been partially mitigated by fixed rates on long-term debt. The Company manages a portion of its price risk related to the sale of coal (excluding coal trading activities) using long-term coal supply agreements (those with terms longer than one year), rather than using derivative instruments. Derivative financial instruments have historically been used to manage the Company's risk exposure to foreign currency exchange rate risk, primarily on Australian dollar expenditures made in its Australian mining platform. This risk has historically been managed using forward contracts and options designated as cash flow hedges, with the objective of reducing the variability of cash flows associated with forecasted foreign currency expenditures. The Company has also used derivative instruments to manage its exposure to the variability of diesel fuel prices used in production in the U.S. and Australia with swaps or options, which it has also designated as cash flow hedges, with the objective of reducing the variability of cash flows associated with forecasted diesel fuel purchases. These risk management activities are collectively referred to as "Corporate Hedging" and are actively monitored for compliance with the Company's risk management policies.

During the fourth quarter of 2015, the Company performed an assessment of its risk of nonperformance with respect to derivative financial instruments designated as cash flow hedges in light of three rating agencies downgrading the Company's corporate credit rating during 2015 and declining financial results. The Company determined its hedging relationships were expected to be "highly effective" throughout 2015 based on its quarterly assessments. However, as a result of a deterioration in the Company's credit profile, the Company could no longer conclude, as of December 31, 2015, that its hedging relationships were expected to be "highly effective" at offseting the changes in the anticipated exposure of the hedged item. Therefore, the Company discontinued the application of cash flow hedge accounting subsequent to December 31, 2015 and changes in the fair value of derivative instruments have been recorded as operating costs and expenses in the accompanying unaudited condensed consolidated statements of operations. Previous fair value adjustments recorded in "Accumulated other comprehensive loss" will be frozen until the underlying transactions impact the Company's earnings.

The Company's Bankruptcy Petitions constituted an event of default under the Company's derivative financial instrument contracts and the counterparties terminated the agreements shortly thereafter in accordance with contractual terms. The terminated positions are first-lien obligations under the Company's secured credit agreement dated September 24, 2013 (as amended, the 2013 Credit Facility). The net settlement liability was accounted for as a prepetition liability subject to compromise without credit valuation adjustments. As of September 30, 2016, the Company had no derivative financial instruments in place in relation to diesel fuel or foreign currency exchange rate.

Based on the previous fair value adjustments of the Company's foreign currency hedge contract portfolio recorded in "Accumulated other comprehensive loss", the net loss expected to be reclassified from comprehensive income to earnings over the next 12 months associated with that hedge program is approximately $68 million. Based on the previous fair value adjustments of the Company’s diesel fuel hedge contract portfolio recorded in “Accumulated other comprehensive loss”, the net loss expected to be reclassified from comprehensive income to earnings over the next 12 months associated with that hedge program is approximately $50 million.

The tables below show the classification and amounts of pre-tax gains and losses related to the Company’s Corporate Hedging derivatives during the three and nine months ended September 30, 2016 and 2015:

Cash Flow Presentation. The Company classifies the cash effects of its Corporate Hedging derivatives within the "Cash Flows From Operating Activities" section of the unaudited condensed consolidated statements of cash flows.

Offsetting and Balance Sheet Presentation

The Company's Corporate Hedging derivative financial instruments were transacted in over-the-counter (OTC) markets with financial institutions under International Swaps and Derivatives Association (ISDA) Master Agreements. Those agreements contain symmetrical default provisions which allow for the net settlement of amounts owed by either counterparty in the event of default or contract termination. The Company offsets its Corporate Hedging asset and liability derivative positions on a counterparty-by-counterparty basis in the condensed consolidated balance sheets, with the fair values of those respective derivatives reflected in “Other current assets,” “Investments and other assets,” “Accounts payable and accrued expenses” and “Other noncurrent liabilities." Though the symmetrical default provisions associated with the Company's Corporate Hedging derivatives exist at the overall counterparty level across its foreign currency and diesel fuel hedging strategy derivative contract portfolios, the Company's accounting policy is to apply counterparty offsetting separately within those derivative contract portfolios for presentation in the condensed consolidated balance sheets because that application is more consistent with the fact that the Company generally net settles its Corporate Hedging derivatives with each counterparty by derivative contract portfolio on a routine basis.

The classification and amount of Corporate Hedging derivative financial instruments presented on a gross and net basis as of December 31, 2015 are presented in the table that follows.

Financial Instrument	Fair Value of Liabilities Presented in the Condensed Consolidated Balance Sheet as of December 31, 2015 (1)
	(Dollars in millions)
Current Liabilities:
Commodity swap contracts	$	86.1
Foreign currency forward contracts	145.6
Total	$	231.7
Noncurrent Liabilities:
Commodity swap contracts	$	37.6
Foreign currency forward contracts	55.1
Total	$	92.7

⁽¹⁾   All commodity swap contracts and foreign currency forward contracts were in a liability position as of December 31, 2015.

See Note 9. "Coal Trading" for information on balance sheet offsetting related to the Company’s coal trading activities.

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.

Financial Instruments Measured on a Recurring Basis. The following tables set forth the hierarchy of the Company’s net financial liability positions for which fair value is measured on a recurring basis:

	December 31, 2015
	Level 1		Level 2		Level 3			Total
	(Dollars in millions)
Commodity swap contracts	—		—		(123.7		)	(123.7		)
Foreign currency contracts	—		—		(200.7		)	(200.7		)
Total net financial liabilities	$	—	$	—	$	(324.4	)	$	(324.4	)

As of September 30, 2016, the Company no longer had any outstanding financial positions.

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:

• Commodity swap contracts — diesel fuel and explosives: valued based on 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, then the Company classifies such contracts as Level 3.

• Foreign currency forward and option contracts: 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.

The following table summarizes the changes related to the Company’s Corporate Hedging derivative financial instruments recurring Level 3 financial liabilities:

	Nine Months Ended
	September 30, 2016
	Commodity Contracts			Foreign Currency Contracts			Total
	(Dollars in millions)
Beginning of period	$	123.7		$	200.7		$	324.4
Total net losses realized/unrealized:
Included in earnings (1)	15.7			(48.0		)	(32.3		)
Settlements / terminations	(139.4		)	(152.7		)	(292.1		)
End of period	$	—		$	—		$	—

⁽¹⁾ Includes reorganization items and realized gains (losses)

The Company had no transfers between Levels 1, 2 and 3 during the three and nine months ended September 30, 2016 or 2015. Transfers into Level 3 of liabilities previously classified in Level 2 during the year ended December 31, 2015 were due to the relative value of unobservable inputs to the total fair value measurement of certain derivative contracts rising above the 10% threshold. The Company’s policy is to value all transfers between levels using the beginning of period valuation.

Other Financial Instruments. The Company used the following methods and assumptions in estimating fair values for other financial instruments as of September 30, 2016 and December 31, 2015:

• 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 with an active trading market when available (Level 2), and otherwise on estimated borrowing rates to discount the cash flows to their present value (Level 3).

The estimated fair value of the Company’s current and long-term debt as of September 30, 2016 is subject to compromise in connection with the Company's plan of reorganization and as such has been excluded from the table below. The carrying amount and estimated fair value of the Company's current and long-term debt as of December 31, 2015 are summarized as follows:

	December 31, 2015
	Carrying Amount		Estimated Fair Value
	(Dollars in millions)
Current and Long-term debt	$	6,241.2	$	1,372.7

Coal Trading [Abstract]

Coal Trading

Coal Trading

The Company engages in the direct and brokered trading of coal and freight-related contracts (coal trading). Except those 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.

The Company includes instruments associated with coal trading transactions as a part of its trading book. Trading revenues from such transactions are recorded in “Other revenues” in the unaudited condensed consolidated statements of operations and include realized and unrealized gains and losses on derivative instruments, including those that arise from coal deliveries related to contracts accounted for on an accrual basis under the normal purchases and normal sales exception. Therefore, the Company has elected the trading exemption surrounding disclosure of its coal trading activities.

Trading (losses) revenues recognized during the three and nine months ended September 30, 2016 and 2015 were as follows:

	Three Months Ended						Nine Months Ended
	September 30,						September 30,
Trading Revenues by Type of Instrument	2016			2015			2016			2015
	(Dollars in millions)
Futures, swaps and options	$	(32.4	)	$	47.7		$	(68.7	)	$	89.4
Physical purchase/sale contracts	13.2			(23.2		)	36.1			(46.7		)
Total trading (losses) revenues	$	(19.2	)	$	24.5		$	(32.6	)	$	42.7

Risk Management

Hedge Ineffectiveness. In some instances, the Company has designated an existing coal trading derivative as a hedge and, thus, the derivative has a non-zero fair value at hedge inception. The “off-market” nature of these derivatives, which is best described as an embedded financing element within the derivative, is a source of ineffectiveness. In other instances, the Company uses a coal trading derivative that settles at a different time, has different quality specifications or has a different location basis than the occurrence of the cash flow being hedged. These collectively yield ineffectiveness to the extent that the derivative hedge contract does not exactly offset changes in the fair value or expected cash flows of the hedged item.

The Company had no coal trading positions designated as cash flow hedges as of September 30, 2016 and December 31, 2015.

Offsetting and Balance Sheet Presentation

The Company's coal trading assets and liabilities include financial instruments, such as swaps, futures and options, cleared through various exchanges, which involve the daily net settlement of closed positions. The Company must post cash collateral, known as variation margin, on exchange-cleared positions that are in a net liability position and receives variation margin when in a net asset position. The Company also transacts in coal trading financial swaps and options through OTC markets with financial institutions and other non-financial trading entities under ISDA Master Agreements, which contain symmetrical default provisions. Certain of the Company's coal trading agreements with OTC counterparties also contain credit support provisions that may periodically require the Company to post, or entitle the Company to receive, initial and variation margin. Physical coal and freight-related purchase and sale contracts included in the Company's coal trading assets and liabilities are executed pursuant to master purchase and sale agreements that also contain symmetrical default provisions and allow for the netting and setoff of receivables and payables that arise during the same time period. The Company offsets its coal trading asset and liability derivative positions, and variation margin related to those positions, on a counterparty-by-counterparty basis in the condensed consolidated balance sheets, with the fair values of those respective derivatives reflected in “Assets from coal trading activities, net” and “Liabilities from coal trading activities, net."

The fair value of assets and liabilities from coal trading activities presented on a gross and net basis as of September 30, 2016 and December 31, 2015 is set forth below:

Affected Line Item in the Condensed Consolidated Balance Sheets	Gross Amounts of Recognized Assets (Liabilities)			Gross Amounts Offset in the Condensed Consolidated Balance Sheets			Variation Margin (Held) Posted (1)			Net Amounts of Assets (Liabilities) Presented in the Condensed Consolidated Balance Sheets

Fair Value Measurements

The following tables set forth the hierarchy of the Company’s net financial asset (liability) coal trading positions for which fair value is measured on a recurring basis as of September 30, 2016 and December 31, 2015:

Physical purchase/sale contracts	—		20.2		(15.6		)	4.6
Total net financial assets (liabilities)	$	—	$	23.5	$	(15.6	)	$	7.9

For Level 1 and 2 financial assets and liabilities, the Company utilizes both direct and indirect observable price quotes, including U.S. interest rate curves; LIBOR yield curves; Chicago Mercantile Exchange (CME) Group, Intercontinental Exchange (ICE), LCH.Clearnet (formerly known as the London Clearing House), NOS Clearing ASA and Singapore Exchange (SGX) contract prices; broker quotes; published indices and other market quotes. Below is a summary of the Company’s valuation techniques for Level 1 and 2 financial assets and liabilities:

• Futures, swaps and options: 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.

• Physical purchase/sale contracts: purchases and sales at locations with significant market activity corroborated by market-based information (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.

Physical purchase/sale contracts include a credit valuation adjustment based on credit and non-performance risk (Level 3). The credit valuation adjustment has not historically had a material impact on the valuation of the contracts resulting in Level 2 classification. However, due to the Company's corporate credit rating downgrades in 2015, the credit valuation adjustments as of September 30, 2016 and December 31, 2015 are considered to be significant unobservable inputs in the valuation of the contracts resulting in Level 3 classification.

The Company's risk management function, which is independent of the Company's commercial trading function, is responsible for valuation policies and procedures, with oversight from executive management. Generally, the Company's Level 3 instruments or contracts are valued using bid/ask price quotations and other market assessments obtained from multiple, independent third-party brokers or other transactional data incorporated into internally-generated discounted cash flow models. Decreases in the number of third-party brokers or market liquidity could erode the quality of market information and therefore the valuation of the Company's market positions. The Company's valuation techniques include basis adjustments to the foregoing price inputs for quality, such as heat rate and sulfur and ash content, location differentials, expressed as port and freight costs, and credit risk. The Company's risk management function independently validates the Company's valuation inputs, including unobservable inputs, with third-party information and settlement prices from other sources where available. A daily process is performed to analyze market price changes and changes to the portfolio. Further periodic validation occurs at the time contracts are settled with the counterparty. These valuation techniques have been consistently applied in all periods presented, and the Company believes it has obtained the most accurate information available for the types of derivative contracts held.

The following table summarizes the quantitative unobservable inputs utilized in the Company's internally-developed valuation models for physical commodity purchase/sale contracts classified as Level 3 as of September 30, 2016:

	Range				Weighted
Input	Low		High		Average
Quality adjustments	2	%	2	%	2	%
Location differentials	9	%	9	%	9	%
Credit and non-performance risk	26	%	26	%	26	%

Significant increases or decreases in the inputs in isolation could result in a significantly higher or lower fair value measurement. The unobservable inputs do not have a direct interrelationship; therefore, a change in one unobservable input would not necessarily correspond with a change in another unobservable input.

The following table summarizes the changes in the Company’s recurring Level 3 net financial assets:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2016			2015			2016			2015

Settlements	4.2			(0.5		)	9.1			(1.3		)
End of period	$	(0.7	)	$	1.3		$	(0.7	)	$	1.3

The Company had no transfers between Levels 1 and 2 during the three and nine months ended September 30, 2016 and 2015. Transfers of liabilities into/out of Level 3 from/to Level 2 during the three and nine months ended September 30, 2016 were due to the relative value of unobservable inputs to the total fair value measurement of certain derivative contracts falling below, or in the case of transfers in rising above, the 10% threshold. The Company’s policy is to value all transfers between levels using the beginning of period valuation.

The following table summarizes the changes in net unrealized (losses) gains relating to Level 3 net financial assets held both as of the beginning and the end of the period:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2016		2015		2016			2015

Credit and Non-performance Risk. 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’s policy is to independently evaluate each customer’s creditworthiness prior to entering into transactions and to regularly monitor the credit extended. If the Company engages in a transaction with a counterparty that does not meet its credit standards, the Company seeks to protect its position by requiring the counterparty to provide an appropriate credit enhancement. Also, when appropriate (as determined by its credit management function), the Company has taken steps to reduce its exposure to customers or counterparties whose credit has deteriorated and who may pose a higher risk of failure to perform under their contractual obligations. These steps include obtaining letters of credit or cash collateral (margin), requiring prepayments for shipments or the creation of customer trust accounts held for the Company’s benefit to serve as collateral in the event of a failure to pay or perform. To reduce its credit exposure related to trading and brokerage activities, the Company seeks to enter into netting agreements with counterparties that permit the Company to offset asset and liability positions with such counterparties and, to the extent required, the Company will post or receive margin amounts associated with exchange-cleared and certain OTC positions. The Company also continually monitors counterparty and contract non-performance risk, if present, on a case-by-case basis.

At September 30, 2016, 65% of the Company’s credit exposure related to coal trading activities with investment grade counterparties, while 11% was with non-investment grade counterparties and 24% was with counterparties that are not rated.

Performance Assurances and Collateral

Certain of the Company’s derivative trading instruments require the parties to provide additional performance assurances whenever a material adverse event jeopardizes one party’s ability to perform under the instrument. If the Company was to sustain a material adverse event (using commercially reasonable standards), its counterparties could request collateralization on derivative trading instruments in net liability positions which, based on an aggregate fair value at September 30, 2016 and December 31, 2015, would have amounted to collateral postings to counterparties of approximately $1 million and $21 million, respectively. As of September 30, 2016, the Company was required to post approximately $4 million in collateral to counterparties for such positions. No collateral was required to be posted to counterparties as of December 31, 2015.

Certain of the Company’s other derivative trading instruments require the parties to provide additional performance assurances whenever a credit downgrade occurs below a certain level, as specified in each underlying contract. The terms of such derivative trading instruments typically require additional collateralization, which is commensurate with the severity of the credit downgrade. During the second quarter of 2016, each of the three rating agencies downgraded the Company's corporate credit rating due to the Bankruptcy Petitions. Despite the rating agencies downgrades, the Company’s additional collateral requirement owed to its counterparties for these ratings based derivative trading instruments would have been zero at September 30, 2016 and December 31, 2015 based on the aggregate fair value of all derivative trading instruments with such features. As of September 30, 2016 and December 31, 2015, no collateral was posted to counterparties to support such derivative trading instruments.

The Company is required to post variation margin on positions that are in a net liability position and is entitled to receive and hold variation margin on positions that are in a net asset position with an exchange and certain of its OTC derivative contract counterparties. At September 30, 2016 and December 31, 2015, the Company posted a net variation margin of $57.9 million and held a net variation margin of $10.7 million, respectively.

In addition to the requirements surrounding variation margin, the Company is required by the exchanges upon which it transacts and by certain of its OTC arrangements to post certain additional collateral, known as initial margin, which represents an estimate of potential future adverse price movements across the Company’s portfolio under normal market conditions. As of September 30, 2016 and December 31, 2015, the Company had posted initial margin of $11.3 million and $9.2 million, respectively, which is reflected in “Other current assets” in the condensed consolidated balance sheets. As of September 30, 2016 and December 31, 2015, the Company was in receipt of $1.3 million and $0.7 million of margin in excess of the required variation and initial margin.

Financing Receivables

The Company's total financing receivables as of September 30, 2016 and December 31, 2015 consisted of the following:

Balance Sheet Classification	September 30, 2016		December 31, 2015
	(Dollars in millions)
Other current assets	$	—	$	20.0
Investments and other assets	68.6		65.2
Total financing receivables	$	68.6	$	85.2

The Company periodically assesses the collectability of accounts and loans receivable by considering factors such as specific evaluation of collectability, historical collection experience, the age of the receivable and other available evidence. Below is a description of the Company's financing receivables outstanding as of September 30, 2016.

Codrilla Mine Project. In 2011, a wholly-owned subsidiary of PEA-PCI, then Macarthur Coal Limited, completed the sale of a portion of its 85% interest in the Codrilla Mine Project to the other participants of the Coppabella Moorvale Joint Venture, afterward retaining 73.3% ownership.The final outstanding installment payment of 40% of the sale price was due upon the earlier of the mine's first coal shipment or a specified date. The sales agreement was amended in the second quarter of 2013 to delay the specified date from March 31, 2015 to June 30, 2016. The remaining balance was received during the nine months ended September 30, 2016. At December 31, 2015, the balance associated with these receivables totaled $20.0 million and was recorded in "Other current assets" in the condensed consolidated balance sheets.

Middlemount. The Company periodically makes loans (Priority Loans) to Middlemount, in which the Company owns a 50% equity interest, pursuant to the related shareholders’ agreement for purposes of funding capital expenditures and working capital requirements. The Priority Loans bear interest at a rate equal to the monthly average 30-day Australian Bank Bill Swap Reference Rate plus 3.5% and expire on December 31, 2016. Based on the existence of letters of support from related entities of the shareholders, the expected timing of repayment of these loans is projected to extend beyond the stated expiration date and so the Company considers these loans to be of a long-term nature. As a result, (i) the foreign currency impact related to the shareholder loans is included in foreign currency translation adjustment in the condensed consolidated balance sheets and the unaudited condensed consolidated statements of comprehensive income and (ii) interest income on the Priority Loans is recognized when cash is received. Refer to Note 2. "Asset Impairment" to the consolidated financial statements included in the Company's Annual Report on form 10-K for the year ended December 31, 2015 for background surrounding the impairment charge recognized in 2015 related to Middlemount. The carrying value of the loans of $58.3 million and $65.2 million was reflected in "Investments and other assets" in the condensed consolidated balance sheets as of September 30, 2016 and December 31, 2015, respectively.

On August 8, 2016, one of the Company's Australian subsidiaries and the other shareholder of Middlemount entered into an agreement to provide a revolving loan (Revolving Loans) to Middlemount not to exceed $60.0 million Australian dollars (Revolving Loan Limit). The Company’s participation in the Revolving Loans will not, at any time, exceed its 50% equity interest of the Revolving Loan Limit. The Revolving Loans bear interest at 15% per annum and expire on December 31, 2017. As of September 30, 2016, the carrying value of the Revolving Loans due to the Company's Australian subsidiary was $10.3 million.

The carrying amounts of the 2013 Term Loan Facility due September 2020, the 6.00% Senior Notes due November 2018, the 6.50% Senior Notes due September 2020, the 6.25% Senior Notes due November 2021, the 10.00% Senior Secured Second Lien Notes due March 2022 (the Senior Secured Second Lien Notes), the 7.875% Senior Notes due November 2026, the Convertible Junior Subordinated Debentures due December 2066 (the Debentures) and the DIP Term Loan Facility (as defined below) have been presented above net of the respective unamortized debt issuance costs and original issue discounts, as applicable.

The Company's consolidated financial statements as of December 31, 2015 were prepared under a going concern opinion, and as such, all of its long-term debt with the exception of the Debentures was classified as current. As of September 30, 2016, all of the Company's long-term debt with the exception of the DIP Term Loan Facility (as defined below) and certain other debt arrangements was recorded in “Liabilities subject to compromise” in the condensed consolidated balance sheets. The DIP Term Loan Facility (as defined below) and certain other debt arrangements were recorded in “Current portion of long-term debt” in the condensed consolidated balance sheets as of September 30, 2016.

During the first quarter of 2016, the Company borrowed $947.0 million under the $1.65 billion revolving credit facility (as amended, the 2013 Revolver) for general corporate purposes. As of the Petition Date, the Company had approximately $675 million letters of credit outstanding on the 2013 Revolver.  Subsequent to the Petition Date, certain counterparties drew on a portion of those letters of credit.  The letters of credit were in place to support various types of obligations, though the most significant items related to bank guarantees in place for certain reclamation obligations in Australia.  The draws required the recording of previously off-balance sheet liabilities, except in certain instances where the Company had previously recorded a liability, and as such have been reflected as additional borrowings under the 2013 Revolver.  The total of such letters of credit was $441.4 million as of September 30, 2016. "Investments and other assets" in the condensed consolidated balance sheets as of September 30, 2016 includes $343.7 million of collateral in support of certain of these obligations.

As a result of filing the Bankruptcy Petitions on April 13, 2016, as discussed in Note 1. "Basis of Presentation", the Company is in default under the 2013 Credit Facility and as such the 2013 Revolver can no longer be utilized.

Additional information regarding the Company's current and long-term debt is outlined in Note 12 to the consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2015.

The filing of the Bankruptcy Petitions constituted an event of default that accelerated Peabody’s obligations under the following debt instruments (collectively, the “Debt Instruments”):

• Indenture governing $1,000.0 million outstanding aggregate principal amount of the Company’s 10.00% Senior Secured Second Lien Notes due 2022, dated as of March 16, 2015, among the Company, U.S. Bank National Association (“U.S. Bank”), as trustee and collateral agent, and the guarantors named therein;

• Indenture governing $650.0 million outstanding aggregate principal amount of the Company’s 6.50% Senior Notes due 2020, dated as of March 19, 2004, among the Company, U.S. Bank and the guarantors named therein, as supplemented;

• Indenture governing $1,518.8 million outstanding aggregate principal amount of the Company’s 6.00% Senior Notes due 2018, dated as of November 15, 2011, among the Company, U.S. Bank and the guarantors named therein;

• Indenture governing $1,339.6 million outstanding aggregate principal amount of the Company’s 6.25% Senior Notes due 2021, dated as of November 15, 2011, by and among the Company, U.S. Bank and the guarantors named therein;

• Indenture governing $250.0 million outstanding aggregate principal amount of the Company’s 7.875% Senior Notes due 2026, dated as of March 19, 2004, among the Company, U.S. Bank and the guarantors named therein, as supplemented;

• Subordinated Indenture governing $732.5 million outstanding aggregate principal amount of the Company’s Convertible Junior Subordinated Debentures due 2066, dated as of December 20, 2006, among the Company and U.S. Bank, as supplemented; and

• Amended and Restated Credit Agreement, as amended and restated as of September 24, 2013 (the 2013 Credit Facility), related to $1,170.0 million outstanding aggregate principal amount of term loans under the 2013 Term Loan Facility and $1,650.0 million in the 2013 Revolver which includes approximately $675 million of posted but undrawn letters of credit and approximately $947 million in outstanding borrowings, by and among the Company, Citibank, N.A., as administrative agent, swing line lender and letter of credit (L/C) issuer, Citigroup Global Markets, Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, BNP Paribas Securities Corp., Crédit Agricole Corporate and Investment Bank, HSBC Securities (USA) Inc., Morgan Stanley Senior Funding, Inc., PNC Capital Markets LLC and RBS Securities Inc., as joint lead arrangers and joint book managers, and the lender parties thereto, as amended by that certain Omnibus Credit Agreement, dated as of February 5, 2015.

During March 2016, the Company elected to exercise the 30-day grace period with respect to a $21.1 million semi-annual interest payment due March 15, 2016 on the 6.50% Senior Notes due September 2020 and a $50.0 million semi-annual interest payment due March 15, 2016 on the Senior Secured Second Lien Notes. The Company filed the Bankruptcy Petitions before the grace period lapsed, which stayed the related interest payments.

As a result of the filing of the Bankruptcy Petitions, all unpaid principal and accrued and unpaid interest related to the Company's Debt Instruments due thereunder became immediately due and payable.  Any efforts to enforce such payment obligations under the Debt Instruments are automatically stayed as a result of the Bankruptcy Petitions, and the creditors’ rights of enforcement in respect of the Debt Instruments are subject to the applicable provisions of the Bankruptcy Code.

The Company is also required to pay monthly adequate protection payments to the First Lien Secured Parties in accordance with the rates defined in the 2013 Credit Facility. The adequate protection payments were recorded as "Interest expense" in the unaudited condensed consolidated statement of operations, which totaled $39.6 million and $64.2 million for the three and nine months ended September 30, 2016, respectively.

The Company has not recorded interest expense on the 6.00% Senior Notes due November 2018, the 6.50% Senior Notes due September 2020, the 6.25% Senior Notes due November 2021, the Debentures, the Senior Secured Second Lien Notes or the 7.875% Senior Notes due November 2026 since the filing of the Bankruptcy Petitions on the Petition Date. The Company's contractual interest obligation was $151.4 million and $417.1 million for the three and nine months ended September 30, 2016, respectively; however, $92.9 million and $173.4 million of interest expense was automatically stayed during the three and nine months ended September 30, 2016, respectively, in accordance with Section 502(b)(2) of the Bankruptcy Code.

DIP Financing

On the Petition Date, the Debtors also filed a motion (the DIP Motion) seeking authorization to use cash collateral and to approve financing (the DIP Financing) under that certain Superpriority Secured Debtor-In-Possession Credit Agreement (the DIP Credit Agreement) by and among the Company as borrower, Peabody Global Funding, LLC, formally known as the Global Center for Energy and Human Development and certain Debtors party thereto as guarantors (the Guarantors and together with the Company, the Loan Parties), the lenders party thereto (the DIP Lenders) and Citibank, N.A. as Administrative Agent (in such capacity, the DIP Agent) and L/C Issuer. The DIP Credit Agreement provides for (i) a term loan not to exceed $500 million (the DIP Term Loan Facility), of which $200 million was made available upon entry of an interim order, the remaining $300 million pending the entry of the final order approving the DIP Credit Agreement (the Final Order), secured by substantially all of the assets of the Loan Parties, subject to certain excluded assets and carve outs and guaranteed by the Loan Parties (other than the Company), which would be used for working capital and general corporate purposes, to cash collateralize letters of credit and to pay fees and expenses, (ii) a cash collateralized letter of credit facility in an amount up to $100 million (the L/C Facility), and (iii) a bonding accommodation facility in an amount up to $200 million consisting of (x) a carve-out from the collateral with superpriority claim status, subject only to the fees carve-out, entitling the authority making any bonding request to receive proceeds of collateral first in priority before distribution to any DIP Lender or other prepetition secured creditor, except for letters of credit issued under the DIP Credit Agreement and/or (y) a letter of credit facility (the Bonding L/C Facility). The aggregate face amount of all letters of credit issued under the L/C Facility and the Bonding L/C Facility shall not at any time exceed $50 million without DIP Lender consent.

The DIP Credit Agreement includes covenants that, subject to certain exceptions, require the Company to maintain certain minimum thresholds of liquidity and consolidated EBITDA and to not exceed a certain maximum capital spend, and limit the ability of the Company and the Guarantors to, among other things: (i) make dispositions of material leases and contracts, (ii) make acquisitions, loans or investments, (iii) create liens on their property, (iv) dispose of assets, (v) incur indebtedness, (vi) merge or consolidate with third parties, (vii) enter into transactions with affiliated entities, and (viii) make material changes to their business activities.

In addition to customary events of default, the DIP Credit Agreement contains the following milestones relating to the Chapter 11 Cases, certain of which milestones have been modified as reflected below pursuant to amendments to the DIP Credit Agreement entered into since the Petition Date, the failure of which, if not cured, amended or waived, would result in an event of default:

• not later than 120 days following the Petition Date, delivery of the U.S. Business Plan and the Australian Business Plan (such plans were delivered to and approved by the DIP Lenders on August 10, 2016);

• not later than the earlier to occur of (i) the date that is three business days following the entry of the Final Order and (ii) the date that is 45 days following the Petition Date, a declaratory judgment action shall be commenced by the Company (without prejudice to the rights of any party-in-interest to commence such a declaratory judgment action or any other proceeding) seeking a determination of the Principal Property Cap (including the amount thereof) and which of the U.S. Mine complexes are Principal Properties (the CNTA Issues), and not later than November 23, 2016, the Bankruptcy Court shall have entered an order determining the CNTA Issues (the CNTA Order Date);

• not later than the later of (i) 30 days following the CNTA Order Date and (ii) December 14, 2016, the filing of an Acceptable Reorganization Plan (as defined below) and related disclosure statement;

• not later than 330 days following the Petition Date, the entry of an order confirming an Acceptable Reorganization Plan and not later than 360 days following the Petition Date, effectiveness of an Acceptable Reorganization Plan.

“Acceptable Reorganization Plan” means a reorganization plan that (i) provides for the termination of the commitments and the payment in full in cash of the obligations under the DIP Credit Agreement (other than contingent indemnification obligations for which no claims have been asserted) on the consummation date of such reorganization plan and (ii) provides for customary releases of the DIP Agent, the DIP Lenders and the L/C Issuer and each of their respective representatives, from any and all claims against the DIP Agent, the DIP Lenders and the DIP L/C Issuer in connection with the DIP Credit Agreement or the cases to the fullest extent permitted by the Bankruptcy Code and applicable law.

On April 15, 2016, the Bankruptcy Court issued an order approving the DIP Motion on an interim basis and authorizing the Loan Parties to, among other things, (i) enter into the DIP Credit Agreement and initially borrow up to $200 million, (ii) obtain a cash collateralized letter of credit facility in the aggregate amount of up to $100 million, and (iii) an accommodation facility for bonding requests in an aggregate stated amount of up to $200 million. On April 18, 2016, the Company entered into the DIP Credit Agreement with the DIP Lenders and borrowed $200 million under the DIP Term Loan Facility. On May 17, 2016, the Bankruptcy Court approved the DIP Financing on a final basis and entered an order to that effect on May 18, 2016. On May 19, 2016, following entry of the Final Order, the Company borrowed the remaining $300 million available under the DIP Term Loan Facility. The DIP Credit Agreement has been amended, as noted above and described in Note 1. "Basis of Presentation".

The scheduled maturity under the DIP Credit Agreement is the earliest of (a) the Scheduled Termination Date, (b) 45 days after the entry of the Interim Order if the Final Order has not been entered prior to the expiration of such 45-day period (as such period may be extended with the consent of certain DIP Lenders), (c) the substantial consummation of a plan of reorganization filed in the cases that is confirmed pursuant to an order entered by the Bankruptcy Court, (d) the acceleration of the loans and the termination of commitments with respect to the DIP Credit Agreement and (e) a sale of all or substantially all of the assets of the Company (or the Loan Parties) pursuant to Section 363 of the Bankruptcy Code. Borrowings under the DIP Term Loan Facility bear interest at an interest rate per annum equal to, at the Company's option (i) LIBOR plus 9.00%, subject to a 1.00% LIBOR floor or (ii) the base rate plus 8.00%.

“Scheduled Termination Date” means the date that is 12 months after the closing date; provided that such date may, at the election of the Company, be extended by up to an additional six months so long as, at the time such extension shall become effective, (w) there shall exist no default under the DIP Credit Agreement, (x) the representations and warranties of the Loan Parties therein shall be true and correct in all material respects, (y) the Company shall have paid or caused to be paid to the DIP Agent for the account of each DIP Lender an extension fee in an amount equal to 2.50% of such DIP Lender’s outstanding exposure under the DIP Term Loan Facility at such time and (z) the Company shall have delivered to the DIP Agent an updated DIP budget covering the additional period to be effected by such extension.

The Company paid aggregate debt issuance costs of $25.6 million during the nine months ended September 30, 2016 related to the DIP Term Loan Facility, which will be amortized over a 12-month period.

Intercompany Loan Agreement

Prior to the Petition Date, the Company made available to its Australian platform a committed $250 million revolving intercompany loan facility (Intercompany Loan Agreement). The Intercompany Loan Agreement is designed to provide liquidity to support the ongoing operations of the Australian business during the Chapter 11 Cases, with draw amounts being tied to operating budgets and subject to certain availability restrictions. In accordance with the terms of the DIP Credit Agreement, the aggregate outstanding principal amount shall not exceed $250 million at any one time, which amount shall be subject to increase by up to $200 million with the written consent of the DIP Lenders. The consent of the DIP Lenders is also required to grant liens valued at 50% or more of the assets collateralizing the Intercompany Loan Agreement; however, as discussed in Note 1. "Basis of Presentation", the DIP Lenders have expressly consented to an amendment or waiver of provisions in the Intercompany Loan Agreement to permit the release or subordination of collateral thereunder, including as a result of potential asset sales, of up to $250 million in cash proceeds in the aggregate over the life of the Intercompany Loan Agreement and the agreement was amended accordingly. As of September 30, 2016, $30.0 million was outstanding on the Intercompany Loan Agreement.

Senior Secured Second Lien Notes Offering

On March 16, 2015, the Company completed the offering of $1.0 billion aggregate principal amount of the Senior Secured Second Lien Notes. The notes were offered to qualified institutional buyers under Rule 144A of the Securities Act of 1933, as amended (the Securities Act), and to non-U.S. persons in transactions outside the U.S. under Regulation S of the Securities Act.

2016 Senior Notes Tender Offer and Redemption

Concurrently with the offering of the Senior Secured Second Lien Notes, the Company commenced a tender offer to repurchase the $650.0 million aggregate principal amount then outstanding of the 7.375% Senior Notes due November 2016 (the 2016 Senior Notes). Consequently, the Company repurchased $566.9 million aggregate principal amount of the 2016 Senior Notes that were validly tendered and not validly withdrawn during March 2015. The Company redeemed the remaining $83.1 million aggregate principal amount of the 2016 Senior Notes on April 15, 2015. In connection with those repurchases, the Company recognized an aggregate loss on early debt extinguishment of $67.8 million in the unaudited condensed consolidated statement of operations for the nine months ended September 30, 2015 comprised of aggregate tender offer and make-whole premiums paid of $66.4 million and the non-cash write-off of associated unamortized debt issuance costs of $1.4 million.

As of September 30, 2016, the Company's qualified plans were expected to be at or above the Pension Protection Act thresholds and therefore are expected to avoid benefit restrictions and at-risk penalties for 2016. During the three and nine months ended September 30, 2016, the Company contributed $0.4 million and $0.5 million respectively, to its qualified pension plans. During the nine months ended September 30, 2016, the Company contributed $0.6 million to its non-qualified pension plans. On November 2, 2015, the Bipartisan Budget Act of 2015 (BBA15) was signed into law, which extends pension funding stabilization provisions that were part of the Highway and Transportation Funding Act of 2014 (HATFA) and the Moving Ahead for Progress in the 21st Century Act of 2012 (MAP-21). Under BBA15, the pension funding stabilization provisions temporarily increased the interest rates used to determine pension liabilities for purposes of minimum funding requirements through 2020. Similar to MAP-21, BBA15 is not expected to change the Company's total required cash contributions over the long term, but is expected to reduce the Company's required cash contributions through 2020 if current interest rate levels persist. Based upon minimum funding requirements in accordance with HATFA and BBA15, the Company expects to contribute approximately $0.5 million to its pension plans to meet minimum funding requirements for its qualified plans in 2016. Contributions to non-qualified pension plans ceased subsequent to April 12, 2016 as a result of filing the Bankruptcy Petitions.

Organizational Realignment

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 global coal industry conditions. Costs associated with restructuring actions can include 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.

In 2016, the Company has continued to drive operational efficiencies, optimize production across its mining platform and control operational and administrative expenses. Included in the Company's unaudited condensed consolidated statements of operations were aggregate restructuring charges, primarily comprised of cash severance costs, of $0.3 million and $1.8 million for the three months ended September 30, 2016 and 2015, respectively, and $15.5 million and $23.0 million, for the nine months ended September 30, 2016 and 2015, respectively.

Restricted Cash

As of September 30, 2016, the Company had restricted cash representing collateral for financial assurances associated with reclamation and other obligations of $70.6 million and $1.4 million included in “Investments and other assets” and "Restricted cash", respectively.  Refer to Note 18. "Financial Instruments and Other Guarantees" for details regarding the remaining $22.8 million in restricted cash.

Take-or-pay Obligations

During the nine months ended September 30, 2016, the Company amended contracts to reduce certain U.S. transportation and logistics costs. In connection with these amendments, the Company will realize a net reduction of approximately $45 million in estimated liquidated damage payments that otherwise would have become due with respect to these take-or-pay obligations in 2017. In connection with these amendments, the Company paid liquidated damages of $15.5 million during the nine months ended September 30, 2016.

Divestitures

In May 2016, the Company completed the sale of its 5.06% participation interest in the Prairie State Energy Campus to the Wabash Valley Power Association for $57.1 million. The Company recognized a gain on sale of $6.2 million related to the transaction, which was classified in "Net gain on disposal of assets" in the unaudited condensed consolidated statement of operations for the nine months ended September 30, 2016.

In May 2016, the Company entered into sale and purchase agreements with Australia-based Pembroke Resources to sell its interest in undeveloped metallurgical reserve tenements in Queensland's Bowen Basin for $64.1 million in cash plus a royalty stream. The transaction included Olive Downs South, Olive Downs South Extended and Willunga tenements. The Company recognized a gain on sale of $2.8 million related to the transaction, which was classified in "Net gain on disposal of assets" in the unaudited condensed consolidated statement of operations for the nine months ended September 30, 2016.

In November 2015, the Company entered into a definitive agreement to sell its New Mexico and Colorado assets to a subsidiary of Bowie Resource Partners, LLC (Bowie) in exchange for cash proceeds of $358 million and the assumption of certain liabilities. Bowie agreed to pay the Company $20 million if it failed to obtain financing within the time frame allotted under the agreement (Termination Fee). Bowie did not obtain the necessary financing within the time allowed under the agreement, nor the additional time Peabody agreed to provide at Bowie's request. On April 12, 2016, Peabody then requested that the Termination Fee be paid, which Bowie has not done. The Company has brought action against Bowie to recover the Termination Fee, interest and certain costs.

Customer Contract Amendment

During the second quarter of 2016, the Company amended its arrangements concerning its long-term supply contract with the largest customer of its Australian Thermal Mining segment as a result of the Debtors' Bankruptcy Petitions. Coal under the supply contract is sourced from the Company's Wilpinjong Mine. The Bankruptcy Petitions enabled the customer to exercise their contractual step-in rights to appoint a receiver to operate the mine within the parameters of the agreement; however, the customer has not exercised this right. Under the new arrangements, the Company's subsidiary agreed to post cash collateral of $50.0 million Australian dollars by September 15, 2016, all of which was posted as of September 30, 2016 and is included in "Investments and other assets" in the condensed consolidated balance sheet. The subsidiary also agreed to maintain compliance with additional covenants and restrictions, including achieving minimum quarterly cash flow and production volumes in relation to specific forecasted amounts. If these conditions are met, the customer will not exercise their step-in rights to appoint a receiver. The arrangements provide for remedial action where certain covenants are not met; but noncompliance could result in termination of the amended arrangements and enable the customer to exercise step-in rights to appoint a receiver to operate the Wilpinjong Mine. As of November 2, 2016, the Company was in compliance with the covenants and restrictions under the new arrangements.

Impact of the Chapter 11 Cases on Certain Leases

The Company leases equipment and facilities under various noncancelable lease agreements. Certain lease agreements were subject to the restrictive covenants of the 2013 Credit Facility and include cross-acceleration provisions, under which the lessor could require certain remedies including, but not limited to, immediate recovery of the present value of any remaining lease payments. In relation to the Company's non-debtor subsidiaries, the Company is in various stages of negotiating stand-still arrangements with some lessors where the lessor will not exercise those rights. The Company does not currently believe it is probable the lessors will exercise those rights for the non-debtor subsidiaries. The lessors' rights related to the Debtor subsidiaries were automatically stayed as a result of the filing of the Chapter 11 Cases. As of September 30, 2016, the Company had approximately $215 million of remaining commitments under these non-debtor lease arrangements.

Earnings per Share (EPS)

Earnings Per Share [Abstract]

Earnings per Share (EPS)

 Earnings per Share (EPS)

Basic and diluted EPS are computed using the two-class method, which is an earnings allocation that determines EPS for each class of common stock and participating securities according to dividends declared and participation rights in undistributed earnings. The Company’s restricted stock awards are considered participating securities because holders are entitled to receive non-forfeitable dividends during the vesting term. Diluted EPS includes securities that could potentially dilute basic EPS during a reporting period, for which the Company includes the Debentures and share-based compensation awards. 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 the performance units, which are further described in Note 18. "Share-Based Compensation" in the Company's Annual Report on Form 10-K for the year ended December 31, 2015, 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 the Company’s 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. For further discussion of the Company’s share-based compensation awards, see Note 18. "Share-Based Compensation" to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015.

A conversion of the Debentures may result in payment for any conversion value in excess of the principal amount of the Debentures in the Company’s common stock. For diluted EPS purposes, potential common stock is calculated based on whether the market price of the Company’s common stock at the end of each reporting period is in excess of the conversion price of the Debentures. For a full discussion of the conditions under which the Debentures may be converted, the conversion rate to common stock and the conversion price, see Note 12. "Long-term Debt" to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. The effect of the Debentures was excluded from the calculation of diluted EPS for all periods presented herein because to do so would have been anti-dilutive for those periods.

The computation of diluted EPS also excluded aggregate share-based compensation awards of approximately 0.4 million and 0.3 million for the three months ended September 30, 2016 and 2015, respectively, and 0.4 million and 0.3 million for the nine months ended September 30, 2016 and 2015, 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.

The following illustrates the earnings allocation method utilized in the calculation of basic and diluted EPS. The number of shares and per share amounts for all periods presented below have been retroactively restated to reflect the Reverse Stock Split discussed in Note 1. "Basis of Presentation."

Financial Instruments And Guarantees With Off Balance Sheet Risk Disclosure [Abstract]

Financial Instruments and Guarantees with Off-Balance-Sheet Risk

Financial Instruments and Other Guarantees

In the normal course of business, the Company is a party to guarantees and financial instruments with off-balance-sheet risk, most of which are not reflected in the accompanying condensed consolidated balance sheets. Such financial instruments are valued based on the amount of exposure under the instrument and the likelihood of required performance.

As of September 30, 2016, the Company had the following financial instruments and other guarantees:

	Reclamation Obligations		Lease Obligations		Workers’ Compensation Obligations		Other (1)		Total		Letters of Credit and Cash Collateral in Support of Financial Instruments
	(Dollars in millions)

Total	$	1,618.3	$	96.7	$	71.1	$	145.9	$	1,932.0	$	315.0

⁽¹⁾  Other includes the $37.0 million in letters of credit related to TXU Europe Limited described below and an additional $108.9 million in bank guarantees, letters of credit and surety bonds related to collateral for road maintenance, performance guarantees and other operations.

The Company owns a 37.5% interest in Dominion Terminal Associates, a partnership that operates a coal export terminal in Newport News, Virginia under a 30-year lease that permits the partnership to purchase the terminal at the end of the lease term for a nominal amount. The partners have severally (but not jointly) agreed to make payments under various agreements which, in the aggregate, provide the partnership with sufficient funds to pay rents and to cover the principal and interest payments on the floating-rate industrial revenue bonds issued by the Peninsula Ports Authority, and which are supported by letters of credit from a commercial bank. On July 1, 2016, $39.9 million of the total $42.7 million of letters of credit supporting the reimbursement obligation to the commercial bank were drawn down to repay the outstanding bonds. As a result, the bonds were retired with the balance of the letters of credit canceled.

The Company is party to an agreement with the PBGC and TXU Europe Limited, an affiliate of the Company’s former parent corporation, under which the Company is required to make contributions to two of the Company’s qualified defined benefit pension plans and to maintain a $37.0 million letter of credit in favor of the PBGC. If the Company or the PBGC gives notice of an intent to terminate one or more of the covered pension plans in which liabilities are not fully funded, or if the Company fails to maintain the letter of credit, the PBGC may draw down on the letter of credit and use the proceeds to satisfy liabilities under the Employee Retirement Income Security Act of 1974, as amended. The PBGC, however, is required to first apply amounts received from a $110.0 million guarantee in place from TXU Europe Limited in favor of the PBGC before it draws on the Company’s letter of credit. On November 19, 2002, TXU Europe Limited was placed under the administration process in the U.K. (similar to a bankruptcy process) and continues under this process as of September 30, 2016. As a result of these proceedings, TXU Europe Limited may be liquidated or otherwise reorganized in such a way as to relieve it of its obligations under its guarantee.

Self-Bonding

During August and September 2016, the Bankruptcy Court approved four motions for Stipulations and Orders (collectively, the “Stipulations”) regarding settlement agreements with the states of Wyoming, New Mexico, Indiana, and Illinois. The Stipulations provide the relevant state authorities with additional financial assurance for the Company’s performance of its reclamation obligations by entitling them to (i) claims in the Chapter 11 Cases that have priority over all administrative expenses of the kind specified in section 503(b) of the Bankruptcy Code for the specified values set forth in the Stipulations and (ii) in the cases of Wyoming, Indiana and Illinois, $0.8 million, $7.5 million and $3.2 million, respectively, in letters of credit or surety bonds related to closed mining operations, together not to exceed the full amount of the $200 million bonding accommodation facility provided for in the DIP Credit Agreement. Each state received financial assurances equal to approximately 17.5% of the Company's prepetition reclamation bond amount with the relevant state. In addition to providing supplemental financial assurances to these states, the Company has agreed to, among other things, quarterly reclamation activity status meetings as well as targeting reductions in the amount of bonds outstanding with these states. Pursuant to the Stipulations, the states will effectively deem the Company’s bonding requirements satisfied for the pendency of the Chapter 11 Cases.

As previously disclosed, the Company's ability to self-bond reduces the Company's costs of securing reclamation obligations and enhances liquidity to the extent alternate forms of bonding would require the Company to post collateral. To the extent the Company is unable to maintain its current level of self-bonding following the conclusion of the Chapter 11 Cases for any reason, the Company would be required to obtain replacement financial assurances or security. Further, self-bonding is permitted at the discretion of each state. As of September 30, 2016, the Company was self-bonded in Illinois, Indiana, New Mexico and Wyoming. The Company is in discussions with Illinois, Indiana, New Mexico and Wyoming regarding the Company’s reclamation bonding over the long term.

Accounts Receivable Securitization

On March 25, 2016, the Company amended and restated its accounts receivable securitization program (securitization program) to, among other things, extend the term of the program by two years to March 23, 2018 and reduce the maximum availability under the facility from $275.0 million to $180.0 million. The accessible capacity of the program varies daily, dependent upon the actual amount of receivables available for contribution and various reserves and limits. As of September 30, 2016, $22.8 million was deposited in a collateral account to secure obligations under the facility.

Under the securitization program, the Company contributes the trade receivables of most of its U.S. subsidiaries on a revolving basis to its wholly-owned, bankruptcy-remote subsidiary (Seller), which then sells the receivables in their entirety to unaffiliated asset-backed commercial paper conduits and banks (the Conduits). After the sale, the Company, as servicer of the assets, collects the receivables on behalf of the Conduits for a nominal servicing fee.

The Seller is a separate legal entity whose assets are available first and foremost to satisfy the claims of its creditors. Of the receivables sold to the Conduits, a portion of the amount due to the Seller is deferred until the ultimate collection of the underlying receivables. During the nine months ended September 30, 2016, the Company received total consideration of $2,109.6 million related to accounts receivable sold under the securitization program, including $1,102.6 million of cash up front from the sale of the receivables, an additional $836.4 million of cash upon the collection of the underlying receivables and $170.6 million that had not been collected at September 30, 2016 and was recorded at carrying value, which approximates fair value. The reduction in accounts receivable as a result of securitization activity with the Conduits was zero and $168.5 million at September 30, 2016 and December 31, 2015, respectively. As of September 30, 2016, $144.9 million in letters of credit remained outstanding under the securitization program.

The securitization activity has been reflected in the unaudited condensed consolidated statements of cash flows as an operating activity because both the cash received from the Conduits upon sale of the receivables as well as the cash received from the Conduits upon the ultimate collection of the receivables are not subject to significantly different risks given the short-term nature of the Company’s trade receivables. The Company recorded expense associated with securitization transactions of $2.4 million and $0.5 million for the three months ended September 30, 2016 and 2015, and $5.6 million and $1.3 million for the nine months ended September 30, 2016 and 2015, respectively.

During the second quarter of 2016, the Company executed two additional amendments to the March 25, 2016 agreement. These amendments permit the continuation of the securitization program through the Company’s Chapter 11 Cases. On April 12, 2016, the Company entered into an amendment to its securitization program to state that the filing of the Bankruptcy Petitions would not result in an automatic termination of the securitization program that would result in the acceleration of the obligations thereunder. On the Petition Date, the Debtors filed a motion seeking Bankruptcy Court approval of the continuation of the securitization program on the terms set forth in the amendments. On April 15, 2016, the Bankruptcy Court entered an order approving this motion on an interim basis. On April 18, 2016, the Company entered into an additional amendment to its securitization program to (i) change the maturity date to the earlier of March 23, 2018 and the emergence of the Company from the Chapter 11 Cases, (ii) revise the schedule of fees and (iii) enter into an additional performance guarantee by the Company’s subsidiaries that are contributors under the securitization facility promising to fulfill obligations of the other contributors. On May 17, 2016, the Bankruptcy Court approved the securitization program on a final basis and entered an order to that effect on May 18, 2016.

Other

Included in "Liabilities subject to compromise" and "Other noncurrent liabilities", respectively, in the Company's condensed consolidated balance sheets as of September 30, 2016 and December 31, 2015 is a liability of $38.4 million related to certain commitments provided on behalf of a third-party coal producer associated with a 2007 purchase of coal reserves and surface lands in the Illinois Basin.

The Company is the lessee under numerous equipment and property leases. It is common in such commercial lease transactions for the Company, as the lessee, to agree to indemnify the lessor 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, would be covered by insurance (subject to deductibles). The Company and certain of its subsidiaries have guaranteed other subsidiaries’ performance under various lease obligations. 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 Company has provided financial guarantees under certain long-term debt agreements entered into by its subsidiaries and 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.

There were no other material changes to the Company’s commitments from the information provided in Note 24 to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015.

Contingencies

From time to time, the Company or its subsidiaries are involved in legal proceedings arising in the ordinary course of business or related to indemnities or historical operations. The Company believes it has recorded adequate reserves for these liabilities. The Company discusses its significant legal proceedings below, including ongoing proceedings and those that impacted the Company's results of operations for the periods presented.

Effect of Automatic Stay. The Debtors filed voluntary petitions for relief under the Bankruptcy Code on the Petition Date in the Bankruptcy Court. Each of the Debtors continues to operate its business and manage its property as a debtor-in-possession pursuant to Sections 1107 and 1108 of the Bankruptcy Code. Subject to certain exceptions under the Bankruptcy Code, the filing of the Debtors’ Chapter 11 Cases, pursuant to Section 362(a) of the Bankruptcy Code, automatically enjoined, or stayed, among other things, the continuation of most judicial or administrative proceedings or the filing of other actions against or on behalf of the Debtors or their property to recover on, collect or secure a claim arising prior to the Petition Date or to exercise control over property of the Debtors’ bankruptcy estates, unless and until the Bankruptcy Court modifies or lifts the automatic stay as to any such claim. Notwithstanding the general application of the automatic stay described above, governmental authorities may determine to continue actions brought under their police and regulatory powers.

The Debtors have filed notices of the bankruptcy filings and suggestions of stay in the applicable domestic matters involving one or more of the Debtors as discussed below and in Note 20. "Matters Related to the Bankruptcy of Patriot Coal Corporation". It is currently unclear whether or how the Company’s Chapter 11 Cases will affect the liabilities described below and in Note 20 or any other contingent liabilities the Debtors may have.

Litigation Relating to Continuing Operations

Peabody Monto Coal Pty Ltd, Monto Coal 2 Pty Ltd and Peabody Energy Australia PCI Pty Ltd (PEA-PCI). In October 2007, a statement of claim was delivered to Peabody Monto Coal Pty Ltd, a wholly-owned subsidiary of PEA-PCI, then Macarthur Coal Limited, and Monto Coal 2 Pty Ltd, an equity accounted investee, from the minority interest holders in the Monto Coal Joint Venture, alleging that Monto Coal 2 Pty Ltd breached the Monto Coal Joint Venture Agreement and Peabody Monto Coal Pty Ltd breached the Monto Coal Management Agreement. Peabody Monto Coal Pty Ltd is the manager of the Monto Coal Joint Venture pursuant to the Management Agreement. Monto Coal 2 Pty Ltd holds a 51% interest in the Monto Coal Joint Venture. The plaintiffs are Sanrus Pty Ltd, Edge Developments Pty Ltd and H&J Enterprises (Qld) Pty Ltd. An additional statement of claim was delivered to PEA-PCI in November 2010 from the same minority interest holders in the Monto Coal Joint Venture, alleging that PEA-PCI induced Monto Coal 2 Pty Ltd and Peabody Monto Coal Pty Ltd to breach the Monto Coal Joint Venture Agreement and the Monto Coal Management Agreement, respectively. The plaintiffs later amended their claim to allege damages for lost opportunities to sell their joint venture interest. These actions, which are pending before the Supreme Court of Queensland, Australia, seek damages from the three defendants collectively of amounts ranging from $15.6 million Australian dollars to $1.8 billion Australian dollars, plus interest and costs. The defendants dispute the claims and are vigorously defending their positions. Based on the Company's evaluation of the issues and their potential impact, the amount of any future loss cannot be reasonably estimated.

Queensland Bulk Handling Pty Ltd.  On June 30, 2014, QBH filed a statement of claim with the Supreme Court of Queensland, Australia, against Peabody (Wilkie Creek) Pty Limited, an indirect wholly-owned subsidiary of the Company, alleging breach of a CPSA between the parties.  QBH originally sought damages of $113.1 million Australian dollars, plus interest and costs.  However, it later altered its claim to seek a declaration that the Company subsidiary had exercised an option to renew the contract for a further term, and withdrew its claim for money damages.

On February 27, 2015, the Supreme Court of Queensland, Australia ruled that QBH and the Company subsidiary were bound to enter into a new CPSA upon substantially the same terms as the 2009 CPSA between them. Under the 2009 CPSA, QBH provided services to Peabody (Wilkie Creek) Pty Limited for operations at the Wilkie Creek Mine, which was closed in 2013. The term of the potential new CPSA would commence January 1, 2015 and expire on December 31, 2026 and, assuming substantially the same contractual terms, would require annual minimum payments of approximately $11.8 million Australian dollars. The Company subsidiary appealed this ruling, which was heard by the Court of Appeal on July 30, 2015. On October 23, 2015, the appellate court upheld this ruling and dismissed the appeal. The Company subsidiary was ordered to pay QBH’s costs of the appeal. In February 2016, QBH served costs statements on the Company subsidiary for attorneys' fees for the appeal and trial and the Company subsidiary is in the process of objecting to the amount of those costs.

On December 8, 2015, QBH filed a claim in the Supreme Court of Queensland, Australia seeking specific performance of the Company subsidiary’s obligation to enter into a new CPSA as described above and payment of $11.8 million Australian dollars representing amounts invoiced by QBH from January through November 2015, plus additional amounts for interest and attorney fees. On January 29, 2016, the Company subsidiary filed a defense to these claims. On February 15, 2016, QBH filed an application for summary judgment, which QBH subsequently agreed to adjourn to a date to be fixed, seeking an order requiring the Company subsidiary to execute a new CPSA and seeking additional amounts invoiced by QBH through February 2016, plus additional interest on these amounts and attorney fees.  On February 29, 2016 QBH filed an amended statement of claim.  The Company subsidiary filed a defense to the amended statement of claim on March 22, 2016.  QBH filed an amended statement of claim in answer to the Company’s amended defense on April 12, 2016. The only change by QBH was to plead that if the Company is correct in its claim that the CPSA was repudiated by the Company and validly terminated by QBH’s acceptance of that repudiation, then QBH claims damages in the alternative. The Company filed an amended defense on May 3, 2016. On May 25, 2016, QBH filed a reply and answer to the Company subsidiary’s amended defense.

As the ultimate impact of the litigation was subject to a wide range of uncertainty, the Company recognized a charge of $9.7 million to discontinued operations during 2015, of which $7.6 million was recorded in the nine months ended September 30, 2015. In September 2016, a settlement was reached under which the Company agreed to pay $13.0 million Australian dollars ($9.9 million USD) to QBH in a full and final settlement of all claims each party had against the other in relation to the CPSA litigation.   A deed of settlement was executed by the parties and the settlement amount was paid to QBH on September 30, 2016.

Lori J. Lynn Class Action. On June 11, 2015, a former Peabody Investments Corp. (PIC) employee filed a putative class action lawsuit in the United States District Court, Eastern District of Missouri on behalf of three of the Company’s or its subsidiaries' 401(k) retirement plans and certain participants and beneficiaries of the plans. The lawsuit, which was brought against Peabody Energy Corporation (PEC), Peabody Holding Company, LLC (PHC), PIC and a number of the Company’s and PIC’s current and former executives and employees, alleges breach of fiduciary duties and seeks monetary damages under the Employee Retirement Income Security Act of 1974 (ERISA) relating to the offering of the Peabody Energy Stock Fund as an investment option in the 401(k) retirement plans.

On September 8, 2015, the plaintiffs filed an amended complaint which, among other things, named a new plaintiff and named all of the current members and two former members of the relevant boards of directors as defendants. The class period (December 2012 to present) remains unchanged. On November 9, 2015, the defendants filed a motion seeking dismissal of all claims.

Plaintiffs filed a second amended complaint on March 11, 2016 that included new allegations against the Company related to the Company's disclosure to investors of risks associated with climate change and related legislation and regulations. The second amended complaint also added the three committees responsible for administering the three 401(k) retirement plans at issue and dropped several individual defendants, including current directors of PEC's board of directors. As a result of filing the Chapter 11 Cases, the plaintiffs voluntarily dismissed the three Debtor defendants (PEC, PIC and PHC) and elected to proceed against the individual defendants and the three named committees with the second amended complaint.

CNTA Dispute. On May 20, 2016, the Company filed a complaint and a request for declaratory judgment in the Bankruptcy Court  against Citibank, N.A. (in its capacity as Administrative Agent under the Company’s 2013 Credit Facility), among others, regarding  the extent of certain collateral and secured claims of certain prepetition creditors. On June 13, 2016, Citibank, N.A. filed an answer and counter-claim for declaratory judgment.  On June 14, 2016, two motions to intervene were filed, one from the Creditors' Committee and another from a group of creditors holding $1.65 billion in face value of the Company's Senior Notes (as indicated in their motion). On June 20, 2016, the Bankruptcy Court entered an order granting the Debtors' motion requesting that the Bankruptcy Court direct all parties to the proceeding to participate in non-binding mediation. The intervention motions were granted on July 7, 2016. On October 7, 2016, a group of creditors holding approximately $287.4 million in face value of the Company’s Senior Secured Second Lien Notes (as indicated in their motion) filed a motion to intervene. The Bankruptcy Court heard oral arguments related to the parties’ motions for summary judgment on September 12, 2016 and subsequently vacated the previously scheduled trial dates and deferred ruling on the matter while the parties continue with mediation. The result of the CNTA Dispute could impact respective recoveries for secured and unsecured creditors in the Chapter 11 Cases.

APS/PacifiCorp Litigation. The Arizona Public Service Company (APS) and PacifiCorp filed a motion in the Bankruptcy Court seeking authorization to allow it to terminate a coal sales agreement, which accounts for approximately half of the Company's El Segundo Mine sales volume. The Company filed a complaint for APS’s and PacifiCorp’s violation of the automatic stay applicable to the Chapter 11 Cases and breach of the coal sales agreement. In September 2016, the parties engaged in a court-ordered mediation. On November 2, the Bankruptcy Court entered an order scheduling the matter for trial beginning on February 13, 2017. The Company intends to vigorously pursue its rights under the coal sales agreement, and against APS/PacifiCorp for the violations of the automatic stay and the coal sales agreement.

Berenergy Corporation. The Company has been in a legal dispute with Berenergy Corporation (Berenergy) regarding Berenergy’s access to certain of its underground oil deposits beneath the Company's North Antelope Rochelle Mine and contiguous undisturbed areas. The Company believes that any claims related to this matter constitute prepetition claims. On October 13, 2016, the Sixth Judicial Court in the state of Wyoming (Wyoming Court) entered an order allowing the Company the right to mine through certain wells owned by Berenergy but required the Company to compensate Berenergy for damages of $0.9 million, which the Company has accrued as of September 30, 2016. Further, the Wyoming Court ruled that should Berenergy obtain approval from the Wyoming Oil and Gas Conservation Commission (the Commission) to recover certain secondary deposits beneath the mine’s contiguous undisturbed areas, the Company would be liable to Berenergy for the cost of certain special procedures and equipment required to access the secondary deposits remotely from outside the Company's mine area, which has been estimated as $13.1 million by Berenergy. The Company believes it is not probable that the Commission will approve access to the secondary deposits based on the Company's view of a lack of economic feasibility and certain restrictions on Berenergy's legal claim to the deposits. The Company is also evaluating the impact of the automatic stay resulting from the Chapter 11 Cases on this matter, which could potentially prevent the Wyoming Court from enforcing its ruling. Based upon these factors, the Company has not accrued a liability related to the secondary deposits as of September 30, 2016. On October 21, 2016, Berenergy filed a motion to lift the automatic stay to allow it to appeal the October 13, 2016 Wyoming Court judgment.

Claims, Litigation and Settlements Relating to Indemnities or Historical Operations

Environmental Claims and Litigation Arising From Historical, Non-Coal Producing Operations. Gold Fields Mining, LLC (Gold Fields) is a non-coal producing entity that was previously managed and owned by Hanson plc, the Company's predecessor owner. In a February 1997 spin-off, Hanson plc transferred ownership of Gold Fields to PEC despite the fact that Gold Fields had no ongoing operations and PEC had no prior involvement in the past operations of Gold Fields. Gold Fields is currently one of PEC's subsidiaries. As part of separate transactions, both PEC and Gold Fields also agreed to indemnify Blue Tee with respect to certain claims relating to the historical operations of a predecessor of Blue Tee, which is a former affiliate of Gold Fields. Neither PEC nor Gold Fields had any involvement with the past operations of the Blue Tee predecessor.

Pursuant to the indemnity, Blue Tee has tendered its environmental claims for remediation, past cost and future costs, and/or natural resource damages (Blue Tee Liabilities) to Gold Fields. Although Gold Fields has paid remediation costs as a result of the indemnification obligations, Blue Tee has been identified as a potentially responsible party (PRP) at various designated national priority list (NPL) sites under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and similar statutes. Of these sites where Blue Tee has been identified as a PRP, neither Gold Fields nor PEC is a party to any cleanup orders relating to the operations of Blue Tee’s predecessor. In addition to the NPL sites, Blue Tee has been named a PRP at multiple other sites, where Gold Fields has either paid remediation costs or settled the environmental claims on behalf of Blue Tee. As a result of filing the Chapter 11 Cases, Gold Fields has now stopped paying these remediation costs.

Environmental assessments for remediation, past and future costs, and/or natural resource damages also have been asserted by the EPA and natural resources trustees against Gold Fields related to historical activities of Gold Fields’ predecessor. Gold Fields has been identified as a PRP at four NPL sites and has been conducting response actions or working with the EPA to resolve past cost recovery claims at these sites pursuant to cleanup orders or other negotiations. As a result of filing the Chapter 11 Cases, Gold Fields has ceased its response actions and other engagements with the EPA at these sites.

Undiscounted liabilities for environmental cleanup-related costs relating to (i) the contractual indemnification obligations owed to Blue Tee and (ii) for the sites noted above for which Gold Fields has been identified as a PRP as a result of the operations of its predecessor, are collectively estimated to be $62.9 million and $66.9 million as of September 30, 2016 and December 31, 2015, respectively, in the condensed consolidated balance sheets. The majority of these estimated costs relate to Blue Tee site liabilities.

Prior to the August 19, 2016 bar date for filing claims in the Chapter 11 Cases, Blue Tee filed an unliquidated, general unsecured claim in the alleged estimated amount of $65.6 million against Gold Fields regarding the Blue Tee Liabilities, additional unliquidated claims in an unknown amount in excess of $150 million at known sites, and further contingent claims at known and unknown sites, including natural resources damages (NRDs) claims alleged, without explanation, to be in the range of $500 million. PEC and Gold Fields plan to contest these claims which they believe to significantly overstate any liabilities that may exist for remediation costs or potential NRDs.

Prior to the October 11, 2016 government bar date for filing claims in the Chapter 11 Cases, several governmental entities including the EPA, the Department of the Interior and several states filed unliquidated, secured and general unsecured claims against PEC and Gold Fields. These claims total in excess of $2.7 billion and allege damages for past and future remediation costs as well as for alleged NRDs at several sites. As noted in the claims, many of the claims are duplicative as they overlap with each other as well as with claims made by Blue Tee. Additionally, PEC and Gold Fields believe the claims significantly overstate any liabilities that may exist for remediation costs or potential NRDs and will contest the claims. The ultimate impact of these matters is subject to a wide range of uncertainties and the Company cannot reasonably estimate its exposure at this time.

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.

Matters Related to the Bankruptcy of Patriot Coal Corporation (Patriot) (Notes)

9 Months Ended

Matters Related to the Bankruptcy of Patriot Coal Corporation (Patriot) [Abstract]

Matters Related to the Bankruptcy of Patriot Coal Corporation (Patriot) [Table Text Block]

Matters Related to the Bankruptcy of Patriot Coal Corporation

In 2012, Patriot filed voluntary petitions for relief under Chapter 11 of 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 Chapter 11 of the Bankruptcy Code in the Eastern District of Virginia and subsequently initiated a process to sell some or 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.

Credit Support

As part of the 2013 Agreement, the Company provided certain credit support to Patriot. The Company has recorded $20.9 million of credit support provided to Patriot as a liability on the Company's condensed consolidated balance sheet as of September 30, 2016, of which $15.7 million was supported by letters of credit.

Black Lung Occupational Disease Liabilities

Patriot has 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 definitive settlement agreement reached in 2013 included Patriot’s affirmance of indemnities provided in the spin-off agreements, including the indemnity relating to such black lung liabilities.

By statute, the Company remains secondarily liable for the black lung liabilities related to Patriot’s workers employed by former subsidiaries of the Company. 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 at September 30, 2016 was $132.9 million. While the Company has recorded a liability, it intends to review each claim on a case-by-case basis and contest liability 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. The Company estimates that the annual cash cost to fund these potential Black Lung liabilities will range between $10 million and $15 million.

UMWA VEBA Payments

In connection with the 2013 Agreement, the Company was required to provide total payments of $310.0 million, payable over four years through 2017, to partially fund the newly established voluntary employee beneficiary association (VEBA) and settle all Patriot and UMWA claims involving the Patriot bankruptcy. Those payments included an initial payment of $90.0 million made in January 2014, comprised of $70.0 million paid to Patriot and $20.0 million paid to the VEBA, and a payment of $75.0 million made in January 2015 to the VEBA. The settlement agreement also contemplated subsequent payments to be made to the VEBA of $75.0 million in 2016 and $70.0 million in 2017.

The parties agreed to a settlement of the Company’s obligations for payment of the remaining VEBA payments (2016 Settlement Agreement), which was approved by the Missouri Bankruptcy Court on January 5, 2016 and the Virginia Bankruptcy Court on January 6, 2016. Under this settlement, the Company agreed to pay $75 million to the VEBA, payable in equal monthly installments of $7.5 million beginning on January 4, 2016. The remaining monthly installments are due at the beginning of each successive month ending October 2016, and the obligations are supported in full by a letter of credit. As a result of the Company’s Chapter 11 Cases, the Company’s obligations to the VEBA under the 2016 Settlement Agreement are being satisfied by monthly draws on the letter of credit by the VEBA trustees. These monthly VEBA payments will terminate early if the VEBA participants can receive healthcare benefits that are reasonably similar to or greater than healthcare benefits provided under the VEBA as a result of new legislation. As part of the settlement, the Company recognized a gain of $68.1 million during the nine months ended September 30, 2016, which was classified in "Operating costs and expenses" in the unaudited condensed consolidated statement of operations and is included in the Company's Corporate and Other segment results.

UMWA 1974 Pension Plan (UMWA Plan) Litigation

On July 16, 2015, a lawsuit was filed by the UMWA Plan, the UMWA 1974 Pension Trust (Trust) and the Trustees of the UMWA Plan and Trust (Trustees) in the United States District Court for the District of Columbia, against PEC, PHC, a subsidiary of the Company, and Arch Coal, Inc. (Arch). The plaintiffs sought, pursuant to ERISA and the Multiemployer Pension Plan Amendments Act of 1980 (MPPAA), a declaratory judgment that the defendants were obligated to arbitrate any opposition to the Trustees’ determination that the defendants have statutory withdrawal liability as a result of the 2015 Patriot bankruptcy. The plaintiffs' lawsuit claimed that the defendants' withdrawal liability would result in at least $767 million owed to the UMWA Plan. PEC and PHC agreed that arbitration was the proper mechanism to dispute any withdrawal liability.  Accordingly, the plaintiffs moved to dismiss the lawsuit against PEC and PHC without prejudice and the court granted the motion.  

On October 29, 2015, the Trustees of the UMWA Plan issued a withdrawal liability assessment against PEC and PHC in the amount of $644.2 million (October 29 Assessment) on the theory that a principal purpose of the Company’s 2007 spin-off of Patriot was to “evade or avoid” withdrawal liability to the UMWA Plan. The Trustees allege that the Company is therefore liable for Patriot's withdrawal liability due to Patriot terminating certain collective bargaining agreements with the UMWA eight years after the spin-off during Patriot's bankruptcy proceeding. PEC and PHC dispute that the Patriot spin-off was an attempt to evade or avoid any obligation to the UMWA Plan. Since more than five years have elapsed since the spin-off of Patriot, the law exempts the Company from making any payments toward the October 29 Assessment unless and until an arbitrator issues a final decision in favor of the Trustees on the "evade or avoid" theory of liability. 

ERISA provides a process to adjudicate withdrawal liability disputes, which consists of administrative review by the UMWA Plan followed by arbitration, after which either side can appeal to the appropriate United States district court. PEC and PHC initiated the administrative review process with the UMWA Plan on January 26, 2016 and the UMWA Plan denied the request on March 18, 2016.  The UMWA Plan initiated arbitration with the AAA on April 7, 2016 (Pension Arbitration). The filing of the Bankruptcy Petitions on April 13, 2016 automatically stayed the Pension Arbitration.

On August 15, 2016, the UMWA Plan filed a claim in the Bankruptcy Court against the Debtors related to the October 29 Assessment in the amount of $642.7 million.  On September 8, 2016, the Debtors filed an objection to the claim in the Bankruptcy Court.  In the objection, the Debtors argued that they are not liable to the UMWA Plan and asked the Bankruptcy Court to disallow the claim in its entirety.  

On September 26, 2016, the UMWA Plan filed a motion to lift the automatic stay to allow the UMWA Plan’s claim to be adjudicated through arbitration, not the claims administration process outlined by the Bankruptcy Code, as articulated in the Stipulation (Lift-Stay Motion).  On October 11, 2016, the Debtors objected to the Lift-Stay Motion on the grounds that the UMWA Plan had not established sufficient cause to lift the automatic stay.  A hearing on the Lift-Stay Motion was held on October 18, 2016, and the Bankruptcy Court granted limited relief from the automatic stay until October 28, 2016 to provide the UMWA Plan until October 28, 2016, to receive a written confirmation from the AAA that the AAA could find an arbitrator with sufficient experience who could arbitrate the UMWA Plan's claim and reach a decision, without extension or any exception for cause, by January 26, 2017. On October 25, 2016, the UMWA Plan filed a copy of its correspondence with the AAA and on October 26, 2016, the Bankruptcy Court issued an order lifting the automatic stay to allow arbitration of the claim to proceed. The parties have selected an arbitrator, and the arbitration hearings are scheduled to begin on December 19, 2016.

During the three months ended September 30, 2016, the Company recognized a charge of $35.0 million, consisting of a $10.0 million cash liability and an allowed unsecured claim of $25.0 million, to "Loss from discontinued operations, net of income taxes" in the unaudited condensed consolidated statement of operations as an estimate of the low end of the range of loss. The top end of the range of reasonably possible loss is $642.7 million, which, as noted above, is the total value of the UMWA Plan's claim.

In accordance with the indentures governing the Senior Notes, certain 100% owned U.S. subsidiaries of the Company (each, a Guarantor Subsidiary) have fully and unconditionally guaranteed the Senior Notes, on a joint and several basis. The indentures governing the Senior Notes contain customary exceptions under which a guarantee of a Guarantor Subsidiary will terminate, including (a) the release or discharge of the guarantee of the Company’s 2013 Credit Facility by such Guarantor Subsidiary, except a discharge or release by or as a result of payment under such guarantee, (b) a sale or other disposition, by way of merger, consolidation or otherwise, of all of the capital stock of such Guarantor Subsidiary, and (c) the legal defeasance or discharge of the indentures. Separate financial statements and other disclosures concerning the Guarantor Subsidiaries are not presented because management believes that such information is not material to the holders of the Senior Notes. The following historical financial statement information is provided for the Guarantor/Non-Guarantor Subsidiaries.

Subsequent Event

On November 3, 2016, Peabody Australia Mining Pty Ltd, one of the Company’s Australian subsidiaries, entered into a definitive share sale and purchase agreement for the sale of all of the equity interests in Metropolitan Collieries Pty Ltd, the entity that owns the Metropolitan mine in New South Wales, Australia and the associated interest in the Port Kembla Coal Terminal, to a subsidiary of South32 Limited (South32). Pursuant to the agreement, the Company will receive cash consideration of $200 million, subject to a customary working capital adjustment. The transaction also includes contingent consideration that enables the Company to share equally with South32 in any revenue above an agreed metallurgical coal price forward curve, after taxes, royalties and appropriate discounts, on all coal sold for the 12 months following completion of the transaction, subject to extension if a minimum amount of coal is not sold during that period. The closing of the transaction is currently anticipated to occur in the first quarter of 2017 and is conditional on receipt of approval from the Australian Competition and Consumer Commission.

The Company determined that, as a result of entering the transaction, and the approval of the Company’s Board of Directors of such a transaction in October 2016, the Metropolitan mine was deemed to meet held-for-sale accounting criteria in the fourth quarter of 2016. Accordingly, the Company expects to record an after-tax impairment charge of approximately $180 million to write down the assets to their estimated selling price, which is the best estimate of fair value under a held-for-sale accounting model. The Company expects to report the impairment charge in its Annual Report on Form 10-K for the year ended December 31, 2016.

Fair Value Transfer Timing Policies (Policy) [Abstract]

Derivatives, Policy [Policy Text Block]

Though the symmetrical default provisions associated with the Company's Corporate Hedging derivatives exist at the overall counterparty level across its foreign currency and diesel fuel hedging strategy derivative contract portfolios, the Company's accounting policy is to apply counterparty offsetting separately within those derivative contract portfolios for presentation in the condensed consolidated balance sheets because that application is more consistent with the fact that the Company generally net settles its Corporate Hedging derivatives with each counterparty by derivative contract portfolio on a routine basis.

Fair Value Transfer, Policy [Policy Text Block]

The Company’s policy is to value all transfers between levels using the beginning of period valuation.

Concentration Risk, Credit Risk, Policy [Policy Text Block]

The Company’s policy is to independently evaluate each customer’s creditworthiness prior to entering into transactions and to regularly monitor the credit extended. If the Company engages in a transaction with a counterparty that does not meet its credit standards, the Company seeks to protect its position by requiring the counterparty to provide an appropriate credit enhancement. Also, when appropriate (as determined by its credit management function), the Company has taken steps to reduce its exposure to customers or counterparties whose credit has deteriorated and who may pose a higher risk of failure to perform under their contractual obligations.

Supplemental Financial Information

Guarantor / Non-Guarantor

In accordance with the indentures governing the Senior Notes, certain 100% owned U.S. subsidiaries of the Company (each, a Guarantor Subsidiary) have fully and unconditionally guaranteed the Senior Notes, on a joint and several basis. The indentures governing the Senior Notes contain customary exceptions under which a guarantee of a Guarantor Subsidiary will terminate, including (a) the release or discharge of the guarantee of the Company’s 2013 Credit Facility by such Guarantor Subsidiary, except a discharge or release by or as a result of payment under such guarantee, (b) a sale or other disposition, by way of merger, consolidation or otherwise, of all of the capital stock of such Guarantor Subsidiary, and (c) the legal defeasance or discharge of the indentures. Separate financial statements and other disclosures concerning the Guarantor Subsidiaries are not presented because management believes that such information is not material to the holders of the Senior Notes. The following historical financial statement information is provided for the Guarantor/Non-Guarantor Subsidiaries.
