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, 2018 include the accounts of Eagle Materials Inc. 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 23, 2018. 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 revenue and expenses during the reporting period. Actual results could differ from those estimates. Recent Accounting Pronouncements RECENTLY ADOPTED In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 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. We adopted the new standard on April 1, 2018 using the modified retrospective approach. The adoption of this standard did not affect 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 adopted the standard on April 1, 2018 using the retrospective method for presentation of service cost and other components in the income statement. We prospectively adopted the requirement to limit the capitalization of benefit cost to the service cost component. The impact of adopting this standard was not material to our financial statements . In January 2017, the FASB issued ASU 2017-04 “Simplifying the Test for Goodwill Impairment,” which eliminates the second step of the goodwill impairment test. Under the new standard, an entity should recognize an impairment charge for the amount by which the carrying value of the reporting unit exceeds the reporting unit’s fair value. This standard is effective for us in the first quarter of fiscal 2021. We adopted this standard effective April 1, 2018, and it will be effective for annual goodwill impairment tests in the fourth quarter of fiscal 2019. PENDING ADOPTION 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 . In January 2018, the FASB issued ASU 2018-01, “Land Easement Practical Expedient for Transition to Topic 842.” This ASU permits the Company to elect not to evaluate land easements under the new lease guidance that existed or expired before the adoption of the ASU 2016-02 and that were not previously accounted for as leases. We will adopt ASU 2018-01 concurrently with the adoption of ASU 2016-02 in the first quarter of fiscal 2020.

REVENUE

REVENUE	3 Months Ended

Revenue From Contract With Customer [Abstract]
REVENUE	(C) REVENUE On April 1, 2018, we adopted the new accounting standard ASU 2014-09 (Topic 606), “Revenue from Contracts with Customers” and all the related amendments to contracts using the modified retrospective method. The adoption of ASU 2014-09 had no impact on our financial statements at the time of the adoption. We earn Revenue primarily from the sale of products, which include cement, concrete, aggregates, gypsum wallboard, recycled paperboard, and frac sand. The vast majority of Revenue from the sale of cement, concrete, aggregates, and gypsum wallboard are originated by purchase orders from our customers, who are primarily third-party contractors and suppliers. Revenue from our Recycled Paperboard and Oil and Gas Proppants segments is generated primarily through long-term supply agreements that mature between 2018 and 2025. We also earn Revenue from transload services and storage; we recognize Revenue from these services when the product is transferred from the rail car to the truck or silo, or from the silo to the railcar or truck. We invoice customers upon shipment, and our collection terms range from 30-65 days. Revenue from the sale of cement, concrete, aggregates and gypsum wallboard that is not related to long-term supply agreements is recognized upon shipment of the related products to customers, which is when title and ownership are transferred and the customer is obligated to pay. Revenue from sales under our long-term supply agreements is also recognized upon transfer of control to the customer, which generally occurs at the time the product is shipped from the production facility or transload location. Our long-term supply agreements with customers define, among other commitments, the volume of product that we must provide and the volume that the customer must purchase by the end of the defined periods. Pricing structures under our agreements are generally market based but are subject to certain contractual adjustments. Historically the pricing and volume requirements under certain of these contracts have been renegotiated during volatile market conditions. Shortfall amounts, if applicable under these arrangements, are constrained and not recognized as Revenue until agreement is reached with the customer and not subject to the risk of reversal. The Company offers certain of its customers, including those with long-term supply agreements, rebates and incentives, which we treat as variable consideration. We adjust the amount of revenue recognized for the variable consideration using the most likely amount method based on past history and projected volumes in the rebate and incentive period. Any amounts billed to customers for taxes are excluded from Revenue. The Company has elected to treat freight and delivery charges we pay for the delivery of goods to our customers as a fulfilment activity rather than a separate performance obligation. When we arrange for a third party to deliver products to customers, fees for shipping and handling that are billed to the customer are recorded as Revenue, while costs we incur for shipping and handling are recorded as expenses and included in Cost of Goods Sold. Other Non-Operating Income (loss) includes lease and rental income, asset sale income, non-inventoried aggregates sales income, distribution center income, and trucking income, as well as other miscellaneous revenue items and costs that have not been allocated to a business segment. See Footnote (M) to the Unaudited Consolidated Financial Statements for disaggregation of revenue by segment.

Receivables [Abstract]
ACCOUNTS AND NOTES RECEIVABLE	(D) ACCOUNTS AND NOTES RECEIVABLE Accounts and Notes Receivable have been shown net of the allowance for doubtful accounts of $8.8 million and $8.6 million at June 30, 2018 and March 31, 2018, respectively. We perform ongoing credit evaluations of our customers’ financial condition and generally require no collateral from our customers. The allowance for non-collection of receivables is based upon analysis of economic trends in the construction industry, detailed analysis of the expected collectability of accounts receivable that are past due and the expected collectability of overall receivables. We have no significant credit risk concentration among our diversified customer base. We had Notes Receivable totaling approximately $5.6 million at June 30, 2018, of which approximately $2.3 million has been classified as current and presented with Accounts Receivable on the balance sheet. We lend funds to certain companies in the ordinary course of business, and the notes bear interest, on average, at LIBOR plus 4.3%. Remaining unpaid amounts, plus accrued interest, mature in fiscal 2021 and 2025. The notes are collateralized by certain assets of the borrowers, namely property and equipment, and are generally payable monthly. We monitor the credit risk of each borrower by assessing the timeliness of payments, credit history, credit metrics, and our ongoing interactions with each borrower.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
SHARE-BASED EMPLOYEE COMPENSATION	(H) S hare On August 7, 2013, our stockholders approved the Eagle Materials Inc. Amended and Restated Incentive Plan (the Plan), which increased the shares we are authorized to issue as awards by 3,000,000 (1,500,000 of which may be stock awards). Under the terms of the Plan, we can issue equity awards, including stock options, restricted stock units (RSUs), restricted stock, and stock appreciation rights to employees of the Company and members of the Board of Directors. Awards that were already outstanding prior to the approval of the Plan on August 7, 2013 remain outstanding. The Compensation Committee of our Board of Directors specifies the terms for grants of equity awards under the Plan. Long-Term Compensation Plans OPTIONS In May 2018, the Compensation Committee of the Board of Directors approved the granting to certain officers and key employees an aggregate of 62,179 performance vesting stock options that will be earned only if certain performance conditions are satisfied (the Fiscal 2019 Employee Performance Stock Option Grant). The performance criteria for the Fiscal 2019 Employee Performance Stock Option Grant is based upon the achievement of certain levels of return on equity (as defined in the option agreements), ranging from 10.0% to 20.0%, for the fiscal year ending March 31, 2019. All stock options will be earned if the return on equity is 20.0% or greater, and the percentage of shares earned will be reduced proportionately to approximately 66.7% if the return on equity is 10.0%. If the Company does not achieve a return on equity of at least 10.0%, all stock options granted will be forfeited. Following any such reduction, restrictions on the earned stock options will lapse ratably over four years, with the initial fourth lapsing promptly following the determination date, and the remaining restrictions lapsing on March 31, 2020 through 2022. The stock options have a term of ten years from the date of grant. The Compensation Committee also approved the granting of 51,814 time vesting stock options to the same officers and key employees, which vest ratably over four years (the Fiscal 2019 Employee Time Vesting Stock Option Grant). The weighted average assumptions used in the Black-Scholes model to value the option awards in fiscal 2018 are as follows: 2018 Dividend Yield 1.3 % Expected Volatility 32.7 % Risk Free Interest Rate 2.88 % Expected Life 6.0 years Stock option expense for all outstanding stock option awards totaled approximately $1.1 million and $0.9 million for the three months ended June 30, 2018 and 2017, respectively. At June 30, 2018, there was approximately $9.5 million of unrecognized compensation cost related to outstanding stock options, which is expected to be recognized over a weighted average period of 2.9 years. The following table represents stock option activity for the three months ended June 30, 2018: Number of Shares Weighted Average Exercise Price Outstanding Options at Beginning of Year 958,136 $ 72.52 Granted 113,993 $ 106.24 Exercised (35,454 ) $ 110.89 Cancelled (2,197 ) $ 100.88 Outstanding Options at End of Year 1,034,478 $ 76.74 Options Exercisable at End of Year 696,466 $ 69.08 Weighted Average Fair Value of Options Granted during the Year $ 34.20 The following table summarizes information about stock options outstanding at June 30, 2018: Options Outstanding Options Exercisable Range of Exercise Prices Number of Shares Outstanding Weighted Average Remaining Contractual Life Weighted Average Exercise Price Number of Shares Outstanding Weighted Average Exercise Price $23.17 - $29.84 65,912 3.10 $ 23.27 65,912 $ 23.27 $33.43 - $37.34 84,582 3.96 $ 33.98 84,582 $ 33.98 $53.22 - $77.67 293,163 6.82 $ 71.27 188,311 $ 70.56 $79.73 - $106.24 590,821 7.66 $ 91.53 357,661 $ 85.05 1,034,478 6.83 $ 76.74 696,466 $ 69.08 At June 30, 2018, the aggregate intrinsic value for outstanding and exercisable options was approximately $29.2 million and $25.0 million, respectively. The total intrinsic value of options exercised during the three months ended June 30, 2018 was approximately $1.9 million. RESTRICTED STOCK In May 2018, the Compensation Committee approved the granting to certain officers and key employees an aggregate of 57,756 shares of performance vesting restricted stock that will be earned if certain performance conditions are satisfied (the Fiscal 2019 Employee Restricted Stock Performance Award). The performance criteria for the Fiscal 2019 Employee Restricted Stock Performance Award is based upon the achievement of certain levels of return on equity (as defined in the award agreement), ranging from 10.0% to 20.0%, for the fiscal year ending March 31, 2019. All restricted shares will be earned if the return on equity is 20.0% or greater, and the percentage of shares earned will be reduced proportionately to approximately 66.7% if the return on equity is 10.0%. If the Company does not achieve a return on equity of at least 10.0%, all awards will be forfeited. Following any such reduction, restrictions on the earned shares will lapse ratably over four years, with the initial fourth lapsing promptly following the determination date, and the remaining restrictions lapsing on March 31, 2020 through 2022. The Compensation Committee also approved the granting of 48,130 shares of time vesting restricted stock to the same officers and key employees, which vest ratably over four years (the Fiscal 2019 Employee Restricted Stock Time Vesting Award). The Fiscal 2019 Employee Restricted Stock Performance Award and the Fiscal 2019 Employee Restricted Stock Time Vesting Award were valued at the closing price of the stock on the date of grant and are being expensed over a four year period. The fair value of restricted stock is based on the stock price at the date of grant. The following table summarizes the activity for nonvested restricted shares during the three months ended June 30, 2018: Number of Shares Weighted Average Grant Date Fair Value Restricted Stock Beginning of Year 328,059 $ 65.76 Granted 105,886 $ 106.24 Vested (25,019 ) $ 88.45 Forfeited (1,990 ) $ 100.88 Nonvested Restricted Stock at End of Year 406,936 $ 76.12 During the three months ended June 30, 2018, the weighted average grant date fair value of restricted shares granted was $106.24. Expense related to restricted shares was approximately $2.4 million and $2.5 million for the three months ended June 30, 2018 and 2017, respectively. At June 30, 2018, there was approximately $26.0 million of unearned compensation from restricted stock, which will be recognized over a weighted average period of 2.7 years. The number of shares available for future grants of stock options, restricted stock units, stock appreciation rights, and restricted stock under the Plan was 3,992,994 at June 30, 2018.

Income Tax Disclosure [Abstract]
INCOME TAXES	(K) INCOME TAXES The Tax Cuts and Jobs Act (the Act) was enacted on December 22, 2017. The Act, among other changes, reduces the U.S. federal corporate tax rate from 35% to 21%, allows for the immediate 100% deductibility of certain capital expenditures, repeals the domestic production deduction, and further limits the deductibility of certain executive compensation. In December 2017, we recorded a tax benefit after the initial assessment of the tax effects of the Act, and we will continue refining this amount throughout December 2018. We are still analyzing certain aspects of the Act and refining our calculations, which could potentially affect the measurement of our deferred tax balance or give rise to new deferred tax amounts in future periods of fiscal 2019. The impact of the Act may differ from our estimate due to changes in the regulations, rulings, guidance, and interpretations issued by the Internal Revenue Service (IRS) and the FASB as well as interpretations and assumptions made by the Company. The calculation of our estimated annual effective tax rate includes the estimated impact of provisions of the Act, including limitations on the deductibility of certain executive compensation. Such estimates could change as additional information becomes available on these provisions of the Tax Act. Income taxes for the interim period presented have been included in the accompanying financial statements on the basis of an estimated annual effective tax rate. In addition to the amount of tax resulting from applying the estimated annual effective tax rate to pre-tax income, we will, when appropriate, include certain items treated as discrete events to arrive at an estimated overall tax amount. The tax rate for the three months ended June 30, 2018 was approximately 22%, which was lower than the tax rate of 31% for the three months ended June 30, 2017. The decline in the rate was primarily due to the passage of the Act and the corresponding changes in U.S. tax law mentioned above.

LONG-TERM DEBT	(L) LONG-TERM DEBT Long-term debt consists of the following: June 30, March 31, 2018 2018 (dollars in thousands) Bank Credit Facility $ 270,000 $ 240,000 4.500% Senior Unsecured Notes Due 2026 350,000 350,000 Private Placement Senior Unsecured Notes 36,500 36,500 Total Debt 656,500 626,500 Less: Debt Origination Costs (5,410 ) (5,578 ) Long-term Debt $ 651,090 $ 620,922 Credit Facility We have a $500.0 million revolving credit facility (the Credit Facility), including a swingline loan sublimit of $25.0 million, which terminates on August 2, 2021. Borrowings under the Credit Facility are guaranteed by substantially all of the Company’s subsidiaries. The debt under the Credit Facility is not rated by ratings agencies. At our option, outstanding principal amounts on the Credit Facility bear interest at a variable rate equal to (i) the London Interbank Offered Rate (LIBOR) plus an agreed margin (ranging from 100 to 225 basis points), which is to be established quarterly based upon the Company’s ratio of consolidated EBITDA, defined as earnings before interest, taxes, depreciation, and amortization, to the Company’s consolidated indebtedness (the Leverage Ratio); or (ii) an alternative base rate which is the higher of (a) the prime rate or (b) the federal funds rate plus 1 2 The Credit Facility has a $40.0 million letter of credit facility. Under the letter of credit facility, the Company pays a fee at a per annum rate equal to the applicable margin for Eurodollar loans in effect from time to time plus a one-time letter of credit fee in an amount equal to 0.125% of the initial stated amount. At June 30, 2018, we had $7.8 million of outstanding letters of credit. 4.500% Senior Unsecured Notes Due 2026 On August 2, 2016, the Company issued $350.0 million aggregate principal amount of 4.500% senior notes (Senior Unsecured Notes) due August 2026. Interest on the Senior Unsecured Notes is payable semiannually on February 1 and August 1 of each year until all of the outstanding notes are paid. The Senior Unsecured Notes rank equal to existing and future senior indebtedness, including the Credit Facility and the Private Placement Senior Unsecured Notes. Prior to August 1, 2019, we may redeem with the proceeds of certain equity offerings up to 40% of the original aggregate principal amount of the Senior Unsecured Notes at a redemption price of 104.5% of the principal amount of the notes. On or after August 1, 2019 and prior to August 1, 2021, we may redeem some or all of the Senior Unsecured Notes at a price equal to 100% of the principal amount, plus a “make-whole” premium. Beginning on August 1, 2021, we may redeem some or all of the Senior Unsecured Notes at the redemption prices set forth below (expressed as a percentage of the principal amount being redeemed): Percentage 2021 102.25 % 2022 101.50 % 2023 100.75 % 2024 and thereafter 100.00 % The Senior Unsecured Notes contain covenants that limit our ability and/or our guarantor subsidiaries' ability to create or permit to exist certain liens; enter into sale and leaseback transactions; and consolidate, merge, or transfer all or substantially all of our assets. The Company’s Senior Unsecured Notes are fully, unconditionally, jointly, and severally guaranteed by each of our subsidiaries that are guarantors under the Credit Facility and Private Placement Senior Unsecured Notes. See Footnote (Q) to the Unaudited Consolidated Financial Statements for more information on the guarantors of the Senior Public Notes. Private Placement Senior Unsecured Notes On October 2, 2007, in a private placement transaction, we entered into a Note Purchase Agreement (the 2007 Note Purchase Agreement) in connection with our sale of $200.0 million of senior unsecured notes, designated as Series 2007A Senior Notes (the Series 2007A Senior Unsecured Notes). The Series 2007A Senior Unsecured Notes, which are guaranteed by substantially all of our subsidiaries, were sold at par and issued in four tranches. At June 30, 2018, the amount outstanding for the remaining tranche is as follows: Principal Maturity Date Interest Rate Tranche D $36.5 million October 2, 2019 6.48 % Interest for the Series 2007A Senior Unsecured Notes is payable semi-annually April 2 and October 2 of each year until all principal is paid for the respective tranche. Our obligations under the 2007 Note Purchase Agreement are equal in right of payment with all other senior, unsecured indebtedness of the Company, including our indebtedness under the Credit Facility and Senior Unsecured Notes. The 2007 Note Purchase Agreement contains customary restrictive covenants, including, but not limited to, covenants that place limits on our ability to encumber our assets, to incur additional debt, to sell assets, or to merge or consolidate with third parties. The 2007 Note Purchase Agreement requires us to maintain a Consolidated Debt to Consolidated EBITDA (calculated as consolidated indebtedness to consolidated earnings before interest, taxes, depreciation, depletion, amortization, certain transaction-related deductions and other non-cash charges) ratio of 3.50 to 1.00 or less, and to maintain an interest coverage ratio (Consolidated EBITDA to Consolidated Interest Expense [calculated as consolidated EBITDA, as defined above, to consolidated interest expense]) of at least 2.50:1.00. In addition, the 2007 Note Purchase Agreement requires the Company to ensure that at all times either (i) Consolidated Total Assets equal at least 80% of the consolidated total assets of the Company and its subsidiaries, determined in accordance with GAAP, or (ii) consolidated Total Revenue of the Company and its restricted subsidiaries for the period of four consecutive fiscal quarters most recently ended equals at least 80% of the consolidated total revenue of the Company and its Subsidiaries during such period. We were in compliance with all financial ratios and tests at June 30, 2018. Pursuant to a Subsidiary Guaranty Agreement, substantially all of our subsidiaries have guaranteed the punctual payment of all principal, interest, and make-whole amounts (as defined in the 2007 Note Purchase Agreement) on the Series 2007A Senior Unsecured Notes and the other payment and performance obligations of the Company contained in the 2007 Note Purchase Agreement. We are permitted, at our option and without penalty, to prepay from time to time at least 10% of the original aggregate principal amount of the Series 2007A Senior Unsecured Notes at 100% of the principal amount to be prepaid, together with interest accrued on such amount to be prepaid to the date of payment, plus a make-whole amount. The make-whole amount is computed by discounting the remaining scheduled principal and interest payments at a discount rate of 50 basis points above the yield to maturity of U.S. Treasury securities having a maturity equal to the remaining average life of the Series 2007A Senior Unsecured Notes being prepaid. We lease one of our cement plants from the city of Sugar Creek, Missouri. The city of Sugar Creek issued industrial revenue bonds to partly finance improvements to the cement plant. The lease payments due to the city of Sugar Creek under the cement plant lease, which was entered into upon the sale of the industrial revenue bonds, are equal in amount to the payments required to be made by the city of Sugar Creek to the holders of the industrial revenue bonds. Because we hold all outstanding industrial revenue bonds, no debt is reflected on our financial statements in connection with our lease of the cement plant. Upon expiration of the lease in fiscal 2021, we have the option to purchase the cement plant for a nominal amount.

Segment Reporting [Abstract]
SEGMENT INFORMATION	(M) SEGMENT INFORMATION Operating segments are defined as components of an enterprise that engage in business activities that earn revenue, incur expenses, and prepare separate financial information that is evaluated regularly by our chief operating decision maker in order to allocate resources and assess performance. We are a leading supplier of heavy construction materials, light building materials, and materials used for oil and natural gas extraction in the United States. Our products are commodities that are essential in commercial and residential construction; public construction projects; projects to build, expand, and repair roads and highways; and in oil and natural gas extraction. Our business is organized into three sectors within which there are five reportable business segments. The Heavy Materials sector includes the Cement and Concrete and Aggregates segments. The Light Materials sector includes the Gypsum Wallboard and Recycled Paperboard segments. The Oil and Gas Proppants segment produces frac sand used in oil and gas exploration and extraction. Our operations are conducted in the U.S. and include the mining of limestone for the manufacture, production, distribution, and sale of portland cement (a basic construction material which is the essential binding ingredient in concrete); the grinding and sale of slag; the mining of gypsum for the manufacture and sale of gypsum wallboard; the manufacture and sale of recycled paperboard to the gypsum wallboard industry and other paperboard converters; the sale of readymix concrete; and the mining and sale of aggregates (crushed stone, sand, and gravel) and sand used in hydraulic fracturing (frac sand). We operate seven cement plants, one slag grinding facility, 18 cement distribution terminals, five gypsum wallboard plants, a gypsum wallboard distribution center, a recycled paperboard mill, 17 readymix concrete batch plants, four aggregates processing plants, two frac sand processing facilities, three frac sand drying facilities, and six frac sand trans-load locations. The principal markets for our cement products are Texas, Illinois, the central plains, Michigan, Iowa, the Rocky Mountains, northern Nevada, southern Ohio, and northern California. Gypsum wallboard and recycled paperboard are distributed throughout the continental U.S., with the exception of the Northeast. Concrete and aggregates are sold to local readymix producers and paving contractors in the Austin, Texas area, north of Sacramento, California; and the greater Kansas City, Missouri area, while frac sand is currently sold into shale deposits across the United States. Other segment operations that are not material to our business are included in Other. We conduct one of our seven cement plant operations, Texas Lehigh Cement Company LP, in Buda, Texas, through a Joint Venture. For segment reporting purposes only, we proportionately consolidate our 50% share of the Joint Venture’s Revenue and Operating Earnings, consistent with the way management reports the segments within the Company for making operating decisions and assessing performance. We account for intersegment sales at market prices. The following table sets forth certain financial information relating to our operations by segment: For the Three Months Ended June 30, 2018 2017 (dollars in thousands) Revenue - Cement $ 186,788 $ 182,935 Concrete and Aggregates 40,840 43,919 Gypsum Wallboard 142,415 126,813 Paperboard 45,133 44,413 Oil and Gas Proppants 21,758 18,910 Other 5,942 — 442,876 416,990 Less: Intersegment Revenue (21,856 ) (22,699 ) Less: Joint Venture Revenue (27,264 ) (28,170 ) $ 393,756 $ 366,121 For the Three Months Ended June 30, 2018 2017 (dollars in thousands) Intersegment Revenue - Cement $ 4,178 $ 4,929 Concrete and Aggregates 331 413 Paperboard 17,347 17,357 $ 21,856 $ 22,699 Cement Sales Volume (M tons) - Wholly Owned 1,275 1,268 Joint Venture 236 243 1,511 1,511 For the Three Months Ended June 30, 2018 2017 (dollars in thousands) Operating Earnings - Cement $ 37,334 $ 43,181 Concrete and Aggregates 5,484 6,021 Gypsum Wallboard 50,480 43,821 Paperboard 9,994 4,938 Oil and Gas Proppants (2,691 ) (2,026 ) Other 284 — Sub-Total 100,885 95,935 Corporate General and Administrative Expense (8,003 ) (9,679 ) Litigation Settlements and Losses (1,800 ) — Other Non-Operating Income 571 757 Earnings Before Interest and Income Taxes 91,653 87,013 Interest Expense, net (6,632 ) (7,483 ) Earnings Before Income Taxes $ 85,021 $ 79,530 Cement Operating Earnings - Wholly Owned $ 28,083 $ 33,305 Joint Ventures 9,251 9,876 $ 37,334 $ 43,181 Capital Expenditures - Cement $ 19,613 $ 7,718 Concrete and Aggregates 2,064 1,412 Gypsum Wallboard 2,355 5,642 Paperboard 1,065 764 Oil and Gas Proppants 27,636 579 Other, net 340 45 $ 53,073 $ 16,160 Depreciation, Depletion and Amortization - Cement $ 12,921 $ 12,479 Concrete and Aggregates 2,053 1,914 Gypsum Wallboard 4,830 4,442 Paperboard 2,109 2,137 Oil and Gas Proppants 7,139 7,606 Corporate and Other 798 369 $ 29,850 $ 28,947 June 30, March 31, 2018 2018 (dollars in thousands) Identifiable Assets Cement $ 1,225,783 $ 1,247,504 Concrete and Aggregates 109,641 104,851 Gypsum Wallboard 386,094 386,041 Paperboard 120,565 123,819 Oil and Gas Proppants 420,075 401,421 Other, net 164,817 104,367 $ 2,426,975 $ 2,368,003 Segment operating earnings, including the proportionately consolidated 50% interest in the revenue and expenses of the Joint Venture, represent Revenue, less direct operating expenses, segment Depreciation, and segment Selling, General and Administrative expenses.

Commitments And Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	(O) COMMITMENTS AND CONTINGENCIES We have certain deductible limits under our workers’ compensation and liability insurance policies for which reserves are established based on the undiscounted estimated costs of known and anticipated claims. We have entered into standby letter of credit agreements relating to workers’ compensation and auto and general liability self-insurance. At June 30, 2018, we had contingent liabilities under these outstanding letters of credit of approximately $7.8 million. In the ordinary course of business, we execute contracts involving indemnifications that are standard in the industry and indemnifications specific to a transaction such as sale of a business. These indemnifications may include claims relating to any of the following: environmental and tax matters; intellectual property rights; governmental regulations and employment-related matters; customer, supplier, and other commercial contractual relationships; construction contracts and financial matters. While the maximum amount to which the Company may be exposed under such agreements cannot be estimated, management believes these indemnifications will not have a material adverse effect on our consolidated financial position, results of operations or cash flows. We currently have no outstanding guarantees. We are currently contingently liable for performance under $26.2 million in performance bonds required by certain states and municipalities and their related agencies. The bonds are principally for certain reclamation obligations and mining permits. We have indemnified the underwriting insurance company against any exposure under the performance bonds. In our past experience, no material claims have been made against these financial instruments. Domestic Wallboard Antitrust Litigation Since late December 2012, several purported class action lawsuits were filed in various United States District Courts, including the Eastern District of Pennsylvania, Western District of North Carolina, and the Northern District of Illinois, against the Company and the Company’s subsidiary, American Gypsum Company LLC (American Gypsum), alleging that the defendant wallboard manufacturers conspired to fix the price for drywall sold in the United States in violation of federal antitrust laws, and in some cases related provisions of state law. In addition to American Gypsum, the defendants in these lawsuits included certain other wallboard manufacturers. These cases were subsequently transferred and consolidated to the Eastern District of Pennsylvania for coordinated pretrial proceedings. The plaintiffs in the consolidated class action complaints asserted claims on behalf of purported classes of direct purchasers or end users of wallboard from January 1, 2012 to the present for unspecified monetary damages (including treble damages) and in some cases injunctive relief. The Company and American Gypsum denied all allegations that they conspired to increase the price of drywall and asserted affirmative defenses to the plaintiffs’ claims. Following completion of the initial discovery, the Company and remaining co-defendants moved for summary judgment. On February 18, 2016, the court denied the Company’s motion for summary judgment. On August 23, 2017, the court granted the direct purchaser plaintiffs’ motion for class certification and certified a class consisting of all persons or entities that purchased paper-backed gypsum wallboard in the United States from January 1, 2012 through January 31, 2013 directly from American Gypsum, the Company, Lafarge, New NGC, PABCO, USG, and/or L&W Supply Corporation (which was a subsidiary of USG Corporation during the class period). In addition, on August 24, 2017, the court denied the indirect purchaser’s motion for class certification. On December 29, 2017 American Gypsum and the Company, as well as New NGC and PABCO, which are not affiliated with the Company, entered into a settlement agreement (the Direct Purchaser Settlement Agreement) with counsel representing the direct purchaser class to settle all claims made against the Company, American Gypsum, New NGC, and PABCO in the direct purchaser class action. The Direct Purchaser Settlement Agreement, in which the Company and American Gypsum deny all wrongdoing, also includes releases by the participating class members of the Company and American Gypsum as well as their subsidiaries, affiliates, and other related parties, for the time period from January 1, 2012 through the date of execution of the Direct Purchaser Settlement Agreement. On January 5, 2018 American Gypsum, New NGC, and PABCO entered into a settlement agreement (the Indirect Purchaser Settlement Agreement) with counsel representing the indirect purchaser class to settle all claims against American Gypsum, New NGC, and PABCO in the indirect purchaser class action. The Indirect Purchaser Settlement Agreement is conditioned on final approval of the District Court. Under the Direct and Indirect Purchaser Settlement Agreements, the Company and American agreed to pay a total of approximately $39.1 million in cash to settle the claims against them. These claims were accrued at the time of the settlements, and during March 2018 we deposited approximately $38.8 million into a qualified settlement fund. The amount accrued under the Direct Purchaser Settlement Agreement was paid in July 2018 after approval by the District Court. In March 2015, a group of homebuilders filed a complaint against the defendants, including American Gypsum, based upon the same conduct alleged in the consolidated class action complaints. In March 2015, the Judicial Panel on Multidistrict Litigation (JPML) transferred this action to the multidistrict litigation already pending in the Eastern District of Pennsylvania. Effective May 8, 2018, American Gypsum and the homebuilder plaintiffs entered into a settlement agreement (the Homebuilder Settlement Agreement) to settle all claims made against American Gypsum. The Homebuilder Settlement Agreement, in which American Gypsum denies all wrongdoing, includes releases by the homebuilder plaintiffs of American Gypsum as well as its subsidiaries, affiliates, and other related parties, for the time period prior to and including the date of execution of the Homebuilder Settlement Agreement. Under the Homebuilder Settlement Agreement, American Gypsum agreed to pay a total of $6.0 million in cash to settle the claims against it. At March 31, 2018, we accrued the total amount of this settlement, and this amount was paid in May 2018. In June 2015, American Gypsum and an employee received grand jury subpoenas from the United States District Court for the Western District of North Carolina seeking information regarding an investigation of the gypsum drywall industry by the Antitrust Division of the Department of Justice. We believe the investigation, although a separate proceeding, is related to the same subject matter at issue in the litigation described above, and we intend to fully cooperate with government officials. Given its preliminary nature, we are currently unable to determine the ultimate outcome of such investigation.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements RECENTLY ADOPTED In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 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. We adopted the new standard on April 1, 2018 using the modified retrospective approach. The adoption of this standard did not affect 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 adopted the standard on April 1, 2018 using the retrospective method for presentation of service cost and other components in the income statement. We prospectively adopted the requirement to limit the capitalization of benefit cost to the service cost component. The impact of adopting this standard was not material to our financial statements . In January 2017, the FASB issued ASU 2017-04 “Simplifying the Test for Goodwill Impairment,” which eliminates the second step of the goodwill impairment test. Under the new standard, an entity should recognize an impairment charge for the amount by which the carrying value of the reporting unit exceeds the reporting unit’s fair value. This standard is effective for us in the first quarter of fiscal 2021. We adopted this standard effective April 1, 2018, and it will be effective for annual goodwill impairment tests in the fourth quarter of fiscal 2019. PENDING ADOPTION 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 . In January 2018, the FASB issued ASU 2018-01, “Land Easement Practical Expedient for Transition to Topic 842.” This ASU permits the Company to elect not to evaluate land easements under the new lease guidance that existed or expired before the adoption of the ASU 2016-02 and that were not previously accounted for as leases. We will adopt ASU 2018-01 concurrently with the adoption of ASU 2016-02 in the first quarter of fiscal 2020.
