(1)	Estimated proven and probable coal reserves have been adjusted to account for estimated process dilutions and losses during mining and processing involved in producing a saleable coal product.

•

Proven (Measured) Reserves — Reserves for which (a) quantity is computed from dimensions revealed in outcrops, trenches, workings or drill holes; grade and/or quality are computed from the results of detailed sampling and (b) the sites for inspection, sampling and measurement are spaced so closely and the geologic character is so well defined that size, shape, depth and mineral content of reserves are well-established.

•

Probable (Indicated) Reserves — Reserves for which quantity and grade and/or quality are computed from information similar to that used for proven (measured) reserves, but the sites for inspection, sampling and measurement are farther apart or are otherwise less adequately spaced. The degree of assurance, although lower than that for proven (measured) reserves, is high enough to assume continuity between points of observation.

Geological settings. The geological characteristics of each mine are among the most important factors that determine the mining cost. Our geology department conducts the exploration program and provides geological models for the LOM process. Coal seam depth, thickness, dipping angle, partings and quality constrain the available mining methods and size of operations. Shallow coal is typically mined by surface mining methods by which the primary cost is overburden removal. Deep coal is typically mined by underground mining methods where the primary costs include coal extraction, conveyance and roof control.

•	Scale of operations and the equipment sizes. For surface mines, our dragline systems generally have a lower unit cost than truck-and-shovel systems for overburden removal. The longwall operations generally are more cost effective than room-and-pillar operations for underground mines.

•	Commodity prices. For surface mines, the costs of diesel fuel and explosives are major components of the total mining cost. For underground mines, the steel used for roof bolts represents a significant cost. Forecasted commodity prices are used to project those costs in the financial models we use to establish our reserves.

•	Target product quality. By targeting a premium quality product, our mining and processing processes may experience more coal losses. By lowering product quality the coal losses can be minimized and therefore a lower cost per ton can be achieved. In our mine plans, the product qualities are estimated to correspond to existing contracts and forecasted market demands.

•	Transportation costs. Transportation costs vary by region. Most of our U.S. operations sell coal at mine loadouts. Therefore, no transportation expenses are included in our U.S. cost estimates. Our Australian operations sell coal at designated ports or local power plants. The estimated costs for our Australian operations include rail transportation and related fees at ports.

•	Royalty costs. Our royalty costs are based upon contractual agreements for the coal leased from governments or private owners. The royalty rates for coal leased from governments differ by country and, in some cases, by mining method. Estimated add-on taxes and other sales-related costs are determined according to government regulations or historic costs.

•	Exchange rates. Costs related to our Australian production are predominantly denominated in Australian dollars, while the Australian coal that we export is sold in U.S. dollars. As a result, Australian/U.S. dollar exchange rates impact the U.S. dollar cost of Australian production.

(1)

Compliance coal is defined by Phase II of the CAA as coal having sulfur dioxide content of 1.2 pounds or less per million Btu. Non-compliance coal is defined as coal having sulfur dioxide content in excess of this standard. Electricity generators are able to use coal that exceeds these specifications by using emissions reduction technology, using emission allowance credits or blending higher sulfur coal with lower sulfur coal.

(2)	As-received Btu per pound includes the weight of moisture in the coal on an as sold basis. The range of variability of the moisture content in coal across a given region may affect the actual shipped Btu content of current production from assigned reserves.

(3)

Coal reserves are estimated based on coal reserves leased from the Navajo Nation and the Hopi Tribe that are administered by the U.S. Department of the Interior. These leases expire upon exhaustion of the leased reserves or upon the permanent ceasing of all mining activities on the related reserves as a whole. The Kayenta Mine serves a single customer and has contract to supply coal to that customer through December 2019. If the customer closes the plant at the end of that contract, proven and probable reserves at the mine would be reduced by approximately 180 million tons. See Item 1A. “Risk Factors” for additional information.

(4)	On November 27, 2017, Peabody completed the sale of the majority of its Burton Mine and related infrastructure to the Lenton Joint Venture.

(5)

Represents our 50% interest in Middlemount Coal Pty Ltd. (Middlemount), which owns the Middlemount Mine in Queensland, Australia. Because that entity is accounted for as an unconsolidated equity affiliate, 2017, 2016 and 2015 tons produced by Middlemount have been excluded from the “Summary of Coal Production and Sulfur Content of Assigned Reserves” table. Middlemount produced 4.3 million tons, 4.5 million tons, and 4.8 million tons of coal in 2017, 2016 and 2015, respectively (on a 100% basis).

(6)	Includes the Wambo Open-Cut Mine and the Wambo Underground Mine areas.

(7)	Assigned reserves represent recoverable coal reserves that are controlled and accessible at active operations as of December 31, 2017. Unassigned reserves represent coal at currently non-producing locations that would require significant new mine development, mining equipment or plant facilities before operations could begin on the property.

(8)

The modifying factors reflect the assumptions which are utilized to convert coal quantities and qualities as in ground to run of mine (ROM) coal after mining, and eventually to saleable product coal after processing. Coal reserves are reported as an estimation of the final saleable quantity, which takes into account any losses and dilutions during mining and processing. We generally keep track of coal reserves through in place coal, ROM coal and product coal. In place coal for U.S. underground reserves excludes planned barrier pillars, but includes regular pillars from projected underground extractions. In place coal for Australian underground reserves is exclusive of all planned pillars. The difference is due to historic practice and software used by each country. The ROM factor represents the estimated ROM coal in relation to the coal in place with considerations of coal losses, dilutions and remaining pillars during mining processes. The yield is the ratio of estimated saleable product coal over ROM coal tons with mainly processing loss considered.

(9)	All coal reserves in Kentucky are leased to third parties.

(3)

We routinely enter into purchase agreements with approved vendors for most types of operating expenses in the ordinary course of business. Our specific open purchase orders (which have not been recognized as a liability) under these purchase agreements, combined with any other open purchase orders, are not material and though they are considered enforceable and legally binding, the related terms generally allow us the option to cancel, reschedule or adjust our requirements based on our business needs prior to the delivery of goods or performance of services. Accordingly, the commitments in the table above relate to orders to suppliers for capital purchases.

(4)	Represents various short- and long-term take or pay arrangements in Australia and the U.S. associated with rail and port commitments for the delivery of coal, including amounts relating to export facilities.

(11)	Income Taxes

•	One-time tax on deferred foreign earnings: The Company does not have any undistributed earnings from its foreign subsidiaries and is not impacted by the one-time transition tax.

•

Repeal of the corporate AMT system: Existing AMT credits as of December 31, 2017 will be refunded over the next four years. The refund may or may not be subject to an IRS budget sequestration reduction rate of approximately 7%. The Company has determined that it will receive a refund of existing AMT credits of approximately $84.9 million after an estimated sequestration reduction of $6.4 million. The valuation allowance previously recorded against these credits has been released and a tax benefit of $84.9 million was recorded as a component of income tax expense from continuing operations. The Company’s accounting policy regarding the balance sheet presentation of the credits is to continue to reflect the balance as a deferred tax asset until a return is filed claiming the credit, at which time the amount will be presented as a tax receivable.

•

Remeasurement of deferred tax assets and liabilities: Deferred tax assets and liabilities attributable to the U.S. were remeasured from 35% to the reduced tax rate of 21%. The Company recorded a provision amount of $473.5 million and an offsetting valuation allowance adjustment for the remeasurement. The Company is still analyzing certain aspects of the Act and refining the calculation, which could potentially affect the measurement of these balances. Filing of both U.S. and foreign tax returns for the 2017 tax years is required to complete the analysis.

•

Elimination of executive compensation exemptions: The Act made major changes to the $1 million limit on deductible compensation paid to certain “covered” employees. The Act eliminated exemptions for qualified performance based compensation and compensation paid after termination and expanded the number of employees to which the limit applies. The Company recorded a provisional amount of $0.5 million and an offsetting valuation allowance adjustment for the impact of these changes. This amount is equal to the elimination of deferred tax assets associated with deferred compensation amounts that will likely exceed the $1 million limit when paid. The Act contains transitional rules, the implementation of which is not entirely clear at this time. The Company is still analyzing related aspects of the Act including the impact of the transitional rules. The provisional amount detailed above may change when further guidance is released that addresses these rules.

•

Changes to international taxation: The Act modifies various aspects of international taxation and the application of these changes to the current foreign tax credit system is unclear. These rules are complex and require further clarity through the issuance of regulations and final technical interpretation. The Company has a deferred tax asset of $1.6 million relating to FTCs that carry a full valuation allowance. Depending on the final interpretation of the new Act, it may be more likely than not that realization of a portion of the credits may occur. The Company has determined that a reasonable estimate cannot be made at this time. Information needed to complete the analysis is as follows: (i) final technical analysis of the new tax law and (ii) finalization of necessary calculations, including an assessment on how these new provisions will impact the utilization of these credits in the future.
