Accounting Policies [Abstract]
BASIS OF PRESENTATION	(A) BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements as of and for the three-month period ended June 30, 2017 include the accounts of Eagle Materials Inc. (“Eagle” or “Parent”) and its majority-owned subsidiaries (collectively, the “Company”, “us” or “we”) and have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission on May 24, 2017. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations, although we believe that the disclosures are adequate to make the information presented not misleading. In our opinion, all adjustments (consisting solely of normal recurring adjustments) necessary to present fairly the information in the following unaudited consolidated financial statements of the Company have been included. The results of operations for interim periods are not necessarily indicative of the results for the full year. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”), issued Accounting Standards Update “(ASU”) 2016-09, “Improvements to Employee Share-Based Payment Accounting,” which provides for simplification of certain aspects of employee share-based payment accounting, including income taxes, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The Company adopted ASU 2016-09 on April 1, 2017. The new standard provides for changes to accounting for stock compensation including 1) excess tax benefits and tax deficiencies related to share based payment awards will be recognized as income tax benefit or expense in the reporting period in which they occur; 2) excess tax benefits will be classified as an operating activity in the statement of cash flow; 3) the option to elect to estimate forfeitures or account for them when they occur; and 4) an increase in the tax withholding requirements threshold to qualify for equity classification. The primary impact of adoption was the recognition of excess tax benefits for our stock awards in the provision for income taxes rather than additional paid-in capital. As provided by the new standard, the Company changed its method of accounting for forfeitures, and will now recognize forfeitures as the occur, which resulted in an approximately $0.7 million reduction to retained earnings. Additional amendments to the accounting for income taxes and minimum statutory withholding tax requirements had no impact to retained earnings. Adoption of the new standard resulted in the recognition of excess tax benefits in our provision for income taxes rather than paid-in capital of $1.0 million for the three months ended June 30, 2017. The presentation of excess tax benefits on stock-based compensation was adopted prospectively within the unaudited Condensed Consolidated Statements of Cash Flows. The presentation requirements for cash flows related to employee taxes paid for withheld shares had no impact to any of the periods presented on the unaudited Condensed Consolidated Statements of Cash Flows as the Company has historically presented them as a financing activity. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The standard will be effective for us in the first quarter of fiscal 2019. We will adopt the new standard using the modified retrospective approach, which requires the standard be applied only to the most current period presented, with the cumulative effect of initially applying the standard recognized at the date of initial application. We are currently performing an evaluation of segments with long-term customer contracts. The businesses with the majority of the long-term customer contracts are not a significant part of our consolidated revenues. We do not expect the adoption of this standard to materially impact our consolidated financial statements, but we are still evaluating the impact on our financial statement disclosures. In March 2017, the FASB issued ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost”, which revises the accounting for periodic pension and postretirement expense. This ASU requires net periodic benefit cost, with the exception of service cost, to be presented retrospectively as nonoperating expense. Service cost will remain a component of cost of goods sold and represent the only cost of pension and postretirement expense eligible for capitalization. We will adopt the standard on April 1, 2018 using the retrospective method for presentation of service cost and other components in the income statement. We will prospectively adopt the requirement to limit the capitalization of benefit cost to the service cost component. The impact of adopting this standard will be a reduction to cost of goods sold and an increase in other expense. Had we adopted this standard on April 1, 2017, our gross profit would have increased by approximately $0.5 million, and other income would have decreased by $0.5 million. In February 2016, the FASB issued ASU 2016-02, “Leases”, which supersedes existing lease guidance to require lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by long-term leases and to disclose additional quantitative and qualitative information about leasing arrangements. The standard will be effective for us in the first quarter of fiscal 2020, and we will adopt using the modified retrospective approach. We are currently assessing the impact of the ASU on our consolidated financial statements and disclosures, as well as our internal lease accounting processes.
