Pension and Savings Plans [Abstract] |
Pension and Savings Plans | Pension and Savings Plans One of the Company’s subsidiaries, Peabody Investments Corp. (PIC), sponsors a defined benefit pension plan covering certain U.S. salaried employees and eligible hourly employees at certain PIC subsidiaries (the Peabody Plan). A subsidiary of PIC also has a defined benefit pension plan covering eligible employees who are represented by the UMWA under the Western Surface Agreement (the Western Plan). Prior to April 2, 2017, PIC also sponsored an unfunded supplemental retirement plan to provide senior management with benefits in excess of limits under the federal tax law (collectively, the Pension Plans). Effective May 31, 2008, the Peabody Plan was frozen in its entirety for both participation and benefit accrual purposes. The Company adopted an enhanced savings plan contribution structure in lieu of benefits formerly accrued under the Peabody Plan. In November 2017, the Company purchased a group annuity contract from an insurance company to pay future pension benefits to approximately 1,950 retirees and beneficiaries of the Peabody Plan. As a result of this transaction, the Company settled $71.4 million of its pension obligation, paid from plan assets. The Company also recorded a settlement charge of $2.1 million as a result of this transaction. Net periodic pension (benefit) cost included the following components:

In connection with fresh start reporting, the Company made a policy election to prospectively record amounts attributable to prior service cost and actuarial valuation changes, as applicable, currently in earnings rather than recording such amounts within accumulated other comprehensive income and amortizing to expense over applicable time periods. The following includes pre-tax amounts recorded in “Accumulated other comprehensive income (loss)”:
| Predecessor
| January 1 through April 1, 2017 |  | Year Ended December 31, 2016 |  | Year Ended December 31, 2015

Total recorded in “Accumulated other comprehensive income (loss)” | $ | (6.4 | ) |  | $ | (18.4 | ) |  | $ | (10.0 | )
Prior to April 2, 2017, the Company amortized actuarial gain and loss using a 5% corridor with a five-year amortization period. The following summarizes the change in benefit obligation, change in plan assets and funded status of the Pension Plans:

The weighted-average assumptions used to determine the benefit obligations as of the end of each year were as follows:
| Successor |  |  | Predecessor
| December 31,
| 2017 |  |  | 2016
Discount rate | 3.70 | % |  |  | 4.15 | %
Measurement date | December 31, 2017 |  |  |  | December 31, 2016 |
The weighted-average assumptions used to determine net periodic pension (benefit) cost during each period were as follows:
| Successor |  |  | Predecessor
| April 2 through December 31, 2017 |  |  | January 1 through April 1, 2017 | Year Ended December 31, 2016 | Year Ended December 31, 2015
Discount rate | 4.10 | % |  |  | 4.15 | % | 4.55 | % | 4.15 | %
Expected long-term return on plan assets | 5.90 | % |  |  | 5.90 | % | 6.00 | % | 6.25 | %
Measurement date | April 1, 2017 |  |  |  | December 31, 2016 |  | December 31, 2015 |  | December 31, 2014 |
The expected rate of return on plan assets is determined by taking into consideration expected long-term returns associated with each major asset class based on long-term historical ranges, inflation assumptions and the expected net value from active management of the assets based on actual results. Effective January 1, 2018, the Company lowered its expected rate of return on plan assets from 5.90% to 5.65% reflecting the impact of the Company’s asset allocation and capital market expectations. The projected benefit obligation and the accumulated benefit obligation exceeded plan assets for all plans as of December 31, 2017 and 2016. The accumulated benefit obligation for all plans was $874.6 million and $959.3 million as of December 31, 2017 and 2016, respectively. Assets of the Pension Plans Assets of the PIC Master Trust (the Master Trust) are invested in accordance with investment guidelines established by the Peabody Plan Retirement Committee and the Peabody Western Plan Retirement Committee (collectively, the Retirement Committees) after consultation with outside investment advisors and actuaries. The asset allocation targets have been set with the expectation that the assets of the Master Trust will be managed with an appropriate level of risk to fund each Pension Plan’s expected liabilities. To determine the appropriate target asset allocations, the Retirement Committees consider the demographics of each Pension Plan’s participants, the funded status of each Pension Plan, the business and financial profile of the Company and other associated risk preferences. These allocation targets are reviewed by the Retirement Committees on a regular basis and revised as necessary. The Retirement Committees have developed and implemented a dynamic asset-liability management investment strategy (the Dynamic Investment Strategy) designed to reduce each Pension Plan’s funded status volatility risk as funded status increases resulting from changes in liabilities due to discount rates and other factors, investment returns and funding contributions. The Dynamic Investment Strategy adjusts allocations between return-seeking (i.e., equities and other similar investments) and liability hedging (i.e., fixed income duration and spread exposure) portfolios in a pre-established manner, with changes triggered when the Pension Plans reach certain funded status thresholds. As of December 31, 2017 and 2016, the Master Trust investment portfolio reflected the Company’s target asset mix of 27% and 31% equity securities and 73% and 69% fixed income investments, respectively. Master Trust assets also include funds invested in various real estate properties representing approximately 2% of total Master Trust assets as of December 31, 2017 and 2016. The Retirement Committees’ intention is to liquidate these real estate holdings when allowable per the terms of the limited partnership agreements. Generally, dissolution and liquidation of the limited partnerships is required before the Master Trust’s real estate holdings can be liquidated and is estimated to occur at various times through 2021. Assets of the Master Trust are either under active management by third-party investment advisors or in index funds, all of which are selected and monitored by the Retirement Committees. Specific investment guidelines have been established by the Retirement Committees for each major asset class including performance benchmarks, allowable and prohibited investment types and concentration limits. In general, investment guidelines do not permit leveraging the assets held in the Master Trust. However, investment managers may employ various strategies and derivative instruments in establishing overall portfolio characteristics consistent with the guidelines and investment objectives established by the Retirement Committees for their portfolios. Equity investment guidelines do not permit entering into put or call options (except as deemed appropriate to manage currency risk), and futures contracts are permitted only to the extent necessary to facilitate liquidity management. Fixed income investment guidelines only allow for exchange-traded derivatives if the investment manager deems the derivative vehicle to be more attractive than a similar direct investment in an underlying cash market or to manage the duration of the fixed income portfolio. A financial instrument’s level within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Following is a description of the valuation techniques and inputs used for investments measured at fair value, including the general classification of such investments pursuant to the valuation hierarchy. Mutual funds. The Master Trust invests in mutual funds for growth and diversification. Investment vehicles include a fund (benchmarked against the performance of the S&P 500 Index) that invests in large-cap publicly traded common stocks (Large-Cap Fund), an institutional fund that holds a diversified portfolio of long-duration corporate fixed income investments (Corporate Bond Fund) and an institutional fund that consists of a diversified portfolio of liquid, short-term instruments of varying maturities (Short-Term Fund). The Large-Cap Fund, which is traded on a national securities exchange in an active market, is valued using daily publicly quoted net asset value (NAV) prices and accordingly classified within Level 1 of the valuation hierarchy. The Corporate Bond Fund and the Short-Term Fund are not traded on a national securities exchange and are valued at NAV, the practical expedient to estimate fair value. Corporate bonds. The Master Trust invests in corporate bonds for diversification, volatility reduction of equity securities and to provide a hedge to interest rate movements affecting liabilities. Investment vehicles include investment-grade corporate bonds. Fair value for these securities is provided by a third-party pricing service that utilizes various inputs such as benchmark yields, reported trades, broker/dealer quotes, issuer spreads and benchmark securities as well as other relevant economic measures. Corporate bonds are classified within the Level 2 valuation hierarchy since fair value inputs are derived prices in active markets and the bonds are not traded on a national securities exchange. U.S. government securities. The Master Trust invests in U.S. government securities for diversification, volatility reduction of equity securities and to provide a hedge to interest rate movements affecting liabilities. Investment vehicles include U.S. government bonds, agency securities and municipal bonds. Fair value for these securities is provided by a third-party pricing service that utilizes various inputs such as benchmark yields, reported trades, broker/dealer quotes, issuer spreads and benchmark securities as well as other relevant economic measures. If fair value is based on quoted prices in active markets and traded on a national securities exchange, U.S. government securities are classified within the Level 1 valuation hierarchy; otherwise, U.S. government securities are classified within the Level 2 valuation hierarchy. International government securities. The Master Trust invests in international government securities for diversification, volatility reduction of equity securities and to provide a hedge to interest rate movements affecting liabilities. Investment vehicles include non-U.S. government bonds. Fair value for these securities is provided by a third-party pricing service that utilizes various inputs such as benchmark yields, reported trades, broker/dealer quotes, issuer spreads and benchmark securities as well as other relevant economic measures. International government securities are classified within the Level 2 valuation hierarchy since fair value inputs are derived prices in active markets and the bonds are not traded on a national securities exchange. Common/collective trusts. The Master Trust invests in common/collective trusts (CCT) for growth and diversification. Investment vehicles include a CCT (benchmarked against the performance of the Russell 2000 Index) that invests in small-cap publicly traded common stocks (the Small-Cap CCT), a CCT that invests in publicly traded non-U.S. equity securities (the Equity CCT) and a CCT (benchmarked against the performance of the MSCI Emerging Markets Index) that primarily invests in equity index securities of companies in global emerging markets (the Equity Index CCT). The Equity CCT and the Equity Index CCT are valued using the closing price reported by their primary stock exchange and translated at each valuation date from local currency into U.S. dollars based on independently published currency exchange rates. The NAV is determined in U.S. dollars and calculated as of the last business day of each month for the Equity CCT and daily for the Equity Index CCT. All CCTs are not traded on a national securities exchange and are valued at NAV, the practical expedient to estimate fair value. Cash funds. The Master Trust invests in cash funds to manage liquidity resulting from payment of participant benefits and certain administrative fees. Investment vehicles primarily include a non-interest bearing cash fund with an earnings credit allowance feature and various exchange-traded derivative instruments consisting of futures and interest rate swap agreements used to manage the duration of certain liability-hedging investments. The non-interest bearing cash fund is classified within the Level 1 valuation hierarchy. Exchange traded derivatives, such as options and futures, for which market quotations are readily available, are valued at the last reported sale price or official closing price on the primary market or exchange on which they are traded and are classified within the Level 1 valuation hierarchy. Real estate investment trusts. The Master Trust invests in real estate interests for diversification. Investments in real estate represent interests in several limited partnerships, which invest in various real estate properties. Interests in real estate are valued using various methodologies, including independent third party appraisals; fair value measurements are not developed by the Company. For some investments, little market activity may exist and determination of fair value is then based on the best information available in the circumstances. This involves a significant degree of judgment by taking into consideration a combination of internal and external factors. Accordingly, interests in real estate are classified within the Level 3 valuation hierarchy. Some limited partnerships issue dividends to their investors in the form of cash distributions that the Pension Plans invest elsewhere within the Master Trust. The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments. The following tables present the fair value of assets in the Master Trust by asset category and by fair value hierarchy:

Contributions Annual contributions to 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%). During the year Successor period April 2 through December 31, 2017, the Company contributed $30.1 million to its qualified pension plans including a discretionary contribution of $25.0 million. The Company did not make any contributions to its qualified and non-qualified plans during the Predecessor period January 1 through April 1, 2017. Effective April 2, 2017, the Company no longer sponsors any non-qualified pension plans. As of December 31, 2017, the Company’s qualified plans are expected to be at or above the Pension Protection Act thresholds. Minimum funding standards are legislated by ERISA and are modified by pension funding stabilization provisions included in the Moving Ahead for Progress in the 21st Century Act of 2012, the Highway and Transportation Funding Act of 2014 and the Bipartisan Budget Act of 2015. Based upon minimum funding requirements, the Company is not required to make any payments to its qualified pension plans to meet minimum funding requirements. Estimated Future Benefit Payments The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid in connection with the Company’s benefit obligation:
| Successor
| Pension Benefits
| (Dollars in millions)
2018 | $ | 57.2 |
2019 | 57.2 |
2020 | 58.6 |
2021 | 59.5 |
2022 | 58.9 |
Years 2023-2027 | 280.1 |
Defined Contribution Plans The Company sponsors employee retirement accounts under two 401(k) plans for eligible U.S. employees. The Company matches voluntary contributions to each plan up to specified levels. The expense for these plans was $25.5 million for the Successor period April 2 through December 31, 2017 and $5.5 million, $19.2 million and $22.0 million for the Predecessor period January 1 through April 1, 2017 and the years ended December 31, 2016 and 2015, respectively. A performance contribution feature in one of the plans allows for additional discretionary contributions from the Company. The performance contribution expected to be paid in 2018, relating to the 2017 plan year is $9.5 million. There were no performance contributions paid during the Successor period April 2 through December 31, 2017, the Predecessor period January 1 through April 1, 2017 or the year ended December 31, 2016. The performance contribution paid during the year ended December 31, 2015 was $19.5 million.
