Accounting Policies [Abstract]
BASIS OF PRESENTATION	(A) BASIS OF PRESENTATION The accompanying Unaudited Consolidated Financial Statements as of and for the three and nine months ended December 31 , 2022, 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 20, 2022. 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 There have been no recent accounting pronouncements that are expected to materially affect the Company.

Business Combinations [Abstract]
ACQUISITIONS	(C) ACQUISITIONS ConAgg Acquisition On April 22, 2022, we purchased the assets of a readymix concrete and aggregates business (the ConAgg Acquisition). The purchase price of the ConAgg Acquisition was approximately $ 121.2 million, which was paid in April 2022. During August 2022, we finalized the working capital adjustment, which resulted in a reduction in the purchase price of approximately $ 1.0 million. After this reduction, the purchase price for the ConAgg Acquisition was approximately $ 120.2 million. The purchase price and expenses incurred in connection with the ConAgg Acquisition were funded through borrowings under our revolving credit facility. Operations related to the ConAgg Acquisition are included in the Concrete and Aggregates business in our segment reporting from April 22, 2022, through December 31, 2022. The following table summarizes the allocation of the Purchase Price to assets acquired and liabilities assumed: Fair Value Working Capital $ 10,780 Property, Plant, and Equipment 39,489 Intangible Assets 30,750 Goodwill 39,135 Total Purchase Price $ 120,154 The estimated useful lives assigned to Property, Plant, and Equipment range from 5 to 30 years , while the estimated useful lives assigned to Intangible Assets range from 2 to 15 years . The following table presents the Revenue and Operating Earnings related to the ConAgg Acquisition that has been included in our Consolidated Statement of Earnings from April 22, 2022, through December 31 , 2022. For the Three Months Ended For the Nine Months Ended December 31, 2022 (dollars in thousands) Revenue $ 9,779 $ 34,694 Operating Earnings $ ( 346 ) $ 1,297 Operating Earnings shown above for the three and nine months ended December 31 , 2022, include approximately $ 2.1 million and $ 6.1 million related to depreciation and amortization, respectively. Additionally, Operating Earnings for the nine months ended December 31, 2022, were negatively affected by approximately $ 2.1 million related to the recording of acquired inventories at fair value. There was no effect on the quarter ended December 31, 2022, as all the acquired inventory was sold by the end of the fiscal second quarter. Terminal Acquisition On September 16, 2022, we acquired a cement distribution terminal located in Nashville, Tennessee (the Terminal Acquisition). The purchase price of the Terminal Acquisition was approximately $ 39.5 million. The purchase price allocation has not been finalized. The Terminal Acquisition was funded through borrowings under our revolving credit facility. Operations related to the Terminal Acquisition are included in the Cement business in our segment reporting from September 16, 2022, through December 31 , 2022. The following table summarizes the preliminary allocation of the Purchase Price of the Terminal Acquisition to the assets acquired and liabilities assumed as of December 31 , 2022: Estimated Fair Value Working Capital $ 1,116 Property, Plant, and Equipment 23,301 Intangible Assets 2,589 Goodwill 12,439 Total Purchase Price $ 39,445 The estimated useful lives assigned to Property, Plant, and Equipment range from 5 to 25 years , while the estimated useful lives assigned to Intangible Assets range from 2 to 15 years .

REVENUE

REVENUE	9 Months Ended
REVENUE	Dec. 31, 2022
Revenue from Contract with Customer [Abstract]
REVENUE	(D) REVENUE We earn Revenue primarily from the sale of products, which include cement, concrete, aggregates, gypsum wallboard, and recycled paperboard. The vast majority of Revenue from the sale of cement, concrete, aggregates, and gypsum wallboard is originated by purchase orders from our customers, who are mostly third-party contractors and suppliers. Revenue from our Recycled Paperboard segment is generated mainly through long-term supply agreements that mature in 2025 and 2026 . We invoice customers upon shipment, and our collection terms range from 30 - 75 days. Revenue from the sale of cement, concrete, aggregates, and gypsum wallboard 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 terminal 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. Shortfall amounts, if applicable under these arrangements, are constrained and not recognized as Revenue until an agreement is reached with the customer and, therefore, are 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 fulfillment 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 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 (N) to the Unaudited Consolidated Financial Statements for disaggregation of revenue by segment.

ACCOUNTS AND NOTES RECEIVABLE	Dec. 31, 2022
Receivables [Abstract]
ACCOUNTS AND NOTES RECEIVABLE	(E) ACCOUNTS AND NOTES RECEIVABLE Accounts Receivable are shown net of the allowance for doubtful accounts totaling $ 6.9 million and $ 6.7 million at December 31 , 2022, and March 31, 2022, 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 $ 8.6 million at December 31 , 2022, of which $ 0.1 million was classified as current. We lend funds to certain companies in the ordinary course of business, and the notes bear interest at LIBOR plus 3 %, which was approximately 6.8 % at December 31 , 2022. Remaining unpaid amounts, plus accrued interest, mature in fiscal 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.

LEASES

LEASES	9 Months Ended
LEASES	Dec. 31, 2022
Leases [Abstract]
LEASES	(H) LEASES We lease certain real estate, buildings, and equipment. Certain of these leases contain escalations of rent over the term of the lease, as well as options for us to extend the term of the lease at the end of the original term. These extensions range from periods of one to 20 years . Our lease agreements do not contain material residual value guarantees or material restrictive covenants. In calculating the present value of future minimum lease payments, we use the rate implicit in the lease if it can be determined. Otherwise, we use our incremental borrowing rate in effect at the commencement of the lease to determine the present value of the future minimum lease payments. Additionally, we lease certain equipment under short-term leases with initial terms of less than 12 months, which are not recorded on the balance sheet. Lease expense for our operating and short-term leases is as follows: For the Three Months Ended December 31, For the Nine Months Ended December 31, 2022 2021 2022 2021 (dollars in thousands) Operating Lease Cost $ 1,953 $ 1,512 $ 5,351 $ 4,592 Short-term Lease Cost 135 233 410 1,044 Total Lease Cost $ 2,088 $ 1,745 $ 5,761 $ 5,636 The Right-of-Use Assets and Lease Liabilities are reflected on our Balance Sheet as follows: December 31, March 31, 2022 2022 (dollars in thousands) Operating Leases Operating Lease Right-of-Use Assets $ 20,651 $ 23,856 Current Operating Lease Liabilities $ 6,006 $ 7,118 Noncurrent Operating Lease Liabilities 25,398 29,212 Total Operating Lease Liabilities $ 31,404 $ 36,330 Future payments for operating leases are as follows (dollars in thousands): Fiscal Year Amount 2023 (remaining three months) $ 2,043 2024 6,363 2025 5,916 2026 4,279 2027 3,540 Thereafter 16,934 Total Lease Payments $ 39,075 Less: Imputed Interest ( 7,671 ) Present Value of Lease Liabilities $ 31,404 Weighted-Average Remaining Lease Term (in years) 10.4 Weighted-Average Discount Rate 3.73 %

SHARE-BASED EMPLOYEE COMPENSATION	Dec. 31, 2022
Share-Based Payment Arrangement [Abstract]
SHARE-BASED EMPLOYEE COMPENSATION	(I) S hare -BASED EMPLOYEE COMPENSATION 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, restricted stock, and stock appreciation rights, to employees of the Company and members of the Board of Directors. The Compensation Committee of our Board of Directors specifies grant terms for awards under the Plan. Long-Term Compensation Plans OPTIONS In May 2022, the Compensation Committee of the Board of Directors approved the granting to certain officers and key employees an aggregate of 25,192 performance-vesting stock options that will be earned only if certain performance conditions are satisfied (the Fiscal 2023 Employee Performance Stock Option Award). The performance criteria for the Fiscal 2023 Employee Performance Stock Option Award are based upon the achievement of certain levels of return on equity (as defined in the option agreement), ranging from 10.0 % to 20.0 %, for the fiscal year ending March 31, 2023. 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 granted stock options will be forfeited. Following any such reduction, restrictions on the earned stock options will lapse and the earned options will vest ratably over four years , with the initial fourth vesting promptly following the date on which the return on equity is determined, and the remaining options vesting every March 31 from 2024 through 2026 . The stock options have a term of 10 years from the grant date. The Compensation Committee also approved the granting of 20,994 time-vesting stock options to the same officers and key employees, which vest ratably over four years (the Fiscal 2023 Employee Time-Vesting Stock Option Award). In August 2022, we granted 3,510 options to members of the Board of Directors (the Fiscal 2023 Board of Directors Stock Option Award). Options granted under the Fiscal 2023 Board of Directors Stock Option Award vest immediately and can be exercised from the grant date until their expiration on the tenth anniversary of the grant date. The Fiscal 2023 Employee Performance Stock Option Award, the Fiscal 2023 Employee Time-Vesting Stock Option Award, and the Fiscal 2023 Board of Directors Stock Option Award were valued at their grant date using the Black-Scholes option pricing model. The weighted-average assumptions used in the Black-Scholes model to value the option awards in fiscal 2023 are as follows: Dividend Yield 0.8 % Expected Volatility 38.2 % Risk-Free Interest Rate 2.9 % Expected Life 6.0 years In addition to the stock options grants described above, from time to time we issue stock options to certain employees. Any options issued are valued using the Black-Scholes options pricing model on the grant date and are expensed over the vesting period. Stock option expense for all outstanding stock option awards totaled approximately $ 0.8 million and $ 2.7 million for the three and nine months ended December 31 , 2022, respectively, and $ 0.9 million and $ 2.6 million for the three and nine months ended December 31 , 2021, respectively. At December 31 , 2022, there was approximately $ 4.0 million of unrecognized compensation cost related to outstanding stock options, which is expected to be recognized over a weighted-average period of 2.3 years. The following table represents stock option activity for the nine months ended December 31 , 2022: Number Weighted- Outstanding Options at March 31, 2022 456,849 $ 83.81 Granted 56,621 $ 125.90 Exercised ( 19,241 ) $ 67.74 Cancelled ( 3,178 ) $ 109.15 Outstanding Options at December 31, 2022 491,051 $ 89.13 Options Exercisable at December 31, 2022 299,948 Weighted-Average Fair Value of Options Granted $ 48.36 The following table summarizes information about stock options outstanding at December 31, 2022: Options Outstanding Options Exercisable Range of Exercise Prices Number of Weighted- Weighted- Number of Weighted- $ 59.32 - $ 81.28 170,995 6.58 $ 62.78 84,185 $ 64.80 $ 87.37 - $ 93.03 151,569 6.07 $ 91.57 109,241 $ 91.57 $ 99.37 - $ 143.09 168,487 6.73 $ 113.68 106,522 $ 106.90 491,051 6.47 $ 89.13 299,948 $ 89.50 At December 31 , 2022, the aggregate intrinsic value for the outstanding and exercisable options was approximately $ 21.6 million and $ 13.0 million, respectively. The total intrinsic value of options exercised during the nine months ended December 31 , 2022 was approximately $ 1.1 million. RESTRICTED STOCK In May 2022, the Compensation Committee approved the granting to certain officers and key employees an aggregate of 50,783 shares of performance-vesting restricted stock that will be earned only if certain performance conditions are satisfied (the Fiscal 2023 Employee Restricted Stock Performance Award). The performance criteria for the Fiscal 2023 Employee Restricted Stock Performance Award are 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, 2023. 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 date on which the return on equity is determined, and the remaining restrictions lapsing every March 31 from 2024 through 2026 . The Compensation Committee also approved the granting of 42,545 shares of time-vesting restricted stock to the same officers and key employees, which vest ratably over four years (the Fiscal 2023 Employee Restricted Stock Time-Vesting Award). The Fiscal 2023 Employee Restricted Stock Performance Award and the Fiscal 2023 Employee Restricted Stock Time-Vesting Award were valued at the closing price of the stock on the grant date and are being expensed over a four-year period. In August 2022, we granted 14,482 shares of restricted stock to members of the Board of Directors (the Fiscal 2023 Board of Directors Restricted Stock Award). Restrictions on these shares will lapse six months after the grant date. The Fiscal 2023 Board of Directors Restricted Stock Award was valued at the closing price of the stock on the grant date and is being expensed over a six-month period. In addition to the restricted stock grants described above, from time to time we issue restricted stock to certain employees. These awards are valued at the closing price of the stock on the grant date and are expensed over the vesting period. The fair value of restricted stock is based on the stock price on the grant date. The following table summarizes the activity for nonvested restricted shares during the nine months ended December 31 , 2022: Number of Shares Weighted-Average Grant Date Fair Value Nonvested Restricted Stock at March 31, 2022 258,779 $ 85.34 Granted 111,230 $ 126.23 Vested ( 55,467 ) $ 108.98 Forfeited ( 3,247 ) $ 124.82 Nonvested Restricted Stock at December 31, 2022 311,295 $ 98.31 Expense related to restricted shares was approximately $ 3.3 million and $ 11.0 million for the three and nine months ended December 31 , 2022, respectively, and $ 3.4 million and $ 8.1 million for the three and nine months ended December 31 , 2021, respectively. At December 31 , 2022, there was approximately $ 20.6 million of unearned compensation from restricted stock, which will be recognized over a weighted-average period of 2.3 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 3,260,309 at December 31 , 2022.

Retirement Benefits [Abstract]
PENSION AND EMPLOYEE BENEFIT PLANS	(K) PENSION AND EMPLOYEE BENEFIT PLANS We sponsor several single-employer defined benefit plans and defined contribution plans, which together cover substantially all our employees. Benefits paid under the single-employer defined benefit plans covering certain hourly employees were historically based on years of service and the employee’s qualifying compensation over the last few years of employment. These plans have been frozen to new participants and new benefits within the last few years, with the last plan becoming frozen during fiscal 2020. Our defined benefit plans are all fully funded, with plan assets exceeding the benefit obligation at March 31, 2022. Due to the frozen status and current funding of the single-employer pension plans, our expected pension expense for fiscal 2023 is less than $ 0.1 million.

INCOME TAXES	(L) INCOME TAXES Income Taxes for the interim periods 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 include, when appropriate, certain items treated as discrete events to arrive at an estimated overall tax amount. The effective tax rate for the nine months ended December 31 , 2022, was approximately 22 %, which was consistent with the effective tax rate of 22 % for the nine months ended December 31 , 2021. The effective tax rate was higher than the U.S. Statutory rate of 21 % mainly due to state income taxes, partially offset by a recognized benefit related to percentage depletion.

LONG-TERM DEBT	(M) LONG-TERM DEBT Long-term Debt at December 31 , 2022 was as follows: December 31, March 31, 2022 2022 (dollars in thousands) Revolving Credit Facility $ 130,000 $ 200,000 2.500 % Senior Unsecured Notes Due 2031 750,000 750,000 Term Loan 195,000 — Total Debt 1,075,000 950,000 Less: Current Portion of Long-term Debt ( 10,000 ) — Less: Unamortized Discounts and Debt Issuance Costs ( 10,785 ) ( 11,735 ) Long-term Debt $ 1,054,215 $ 938,265 Revolving Credit Facility We have an unsecured $ 750.0 million revolving credit facility that was amended on May 5, 2022 (such facility, as amended, the Revolving Credit Facility). The Revolving Credit Facility includes a separate $ 200.0 million term loan facility (the Term Loan) and also provides the Company the option to increase the revolving borrowing capacity by up to $ 375.0 million (for a total revolving borrowing capacity of $ 1,125.0 million, excluding the Term Loan), provided that the existing lenders, or new lenders, agree to such increase. The Revolving Credit Facility includes a $ 40.0 million letter of credit facility and a swingline loan sub-facility of $ 25.0 million, and expires on May 5, 2027. The Revolving Credit Facility contains customary covenants for an unsecured investment-grade facility, including covenants that restrict the Company’s and/or its subsidiaries’ ability to incur additional debt; encumber assets; merge with or transfer or sell assets to other persons; and enter into certain affiliate transactions. The Revolving Credit Facility also requires the Company to maintain at the end of each fiscal quarter a Leverage Ratio of 3.50 :1.00 or less and an Interest Coverage Ratio (both ratios, as defined in the Revolving Credit Facility) equal to or greater than 2.50 :1.00 (collectively, the Financial Covenants). At the Company’s option, outstanding loans under the Revolving Credit Facility bear interest, at a variable rate equal to either (i) the adjusted term SOFR rate (secured overnight financing rate), plus 10 bps, plus an agreed spread (ranging from 100 to 162.5 basis points, which is established based on the Company's credit rating); (ii) in respect of any Revolving Loans (until such time as the then-existing Benchmark (as defined in the Revolving Credit Facility) is replaced in accordance with the Revolving Credit Facility), the adjusted daily simple SOFR rate, plus 10 bps, plus an agreed spread (ranging from 100 to 162.5 basis points, which is established based on the Company's credit rating) or (iii) an Alternate Base Rate (as defined in the Revolving Credit Facility), which is the highest of (a) the Prime Rate (as defined in the Revolving Credit Facility) in effect on any applicable day, (b) the NYFRB Rate (as defined in the Revolving Credit Facility) in effect on any applicable day, plus ½ of 1% , and (c) the Adjusted Term SOFR (as defined in the Revolving Credit Facility) for a one-month interest period on any applicable day, or if such day is not a business day, the immediately preceding business day, plus 1.0%, in each case plus an agreed upon spread (ranging from 0 to 62.5 basis points) which is established quarterly based on the Company's credit rating. The Company is also required to pay a facility fee on unused available borrowings under the Revolving Credit Facility ranging from 9 to 22.5 basis points which is established based on the Company's then credit rating. The Company pays each lender a participation fee with respect to such lender’s participations in letters of credit, which fee accrues at the same Applicable Rate (as defined in the Revolving Credit Facility) used to determine the interest rate applicable to Eurodollar Revolving Loans (as defined in the Revolving Credit Facility) plus a fronting fee for each letter of credit issued by the issuing bank in an amount equal to 12.5 basis points per annum on the daily maximum amount then available to be drawn under such letter of credit. The Company also pays each issuing bank such bank’s standard fees with respect to issuance, amendment or extensions of letters of credit and other processing fees, and other standard costs and charges relating to such issuing bank’s letters of credit from time to time. There was $ 130.0 million of outstanding borrowings under the Revolving Credit Facility, plus $ 6.4 million outstanding letters of credit as of December 31, 2022, leaving us with $ 613.6 million of available borrowings under the Revolving Credit Facility, net of the outstanding letters of credit. We were in compliance with all Financial Covenants on December 31 , 2022; therefore, all $ 613.6 million is available for future borrowings. Term Loan On May 5, 2022, we borrowed the $ 200.0 million Term Loan under the Revolving Credit Facility, and used these proceeds to, among other things, pay down a portion of the Revolving Credit Facility. The Term Loan requires quarterly principal payments of $ 2.5 million, with any unpaid amounts due upon maturity on May 5, 2027 . At the Company’s option, principal amounts outstanding under the Term Loan bear interest as set forth in the Revolving Credit Facility (but not, for the avoidance of doubt, at a daily simple SOFR rate unless and until such time as the then-existing Benchmark (as defined in the Revolving Credit Facility) is replaced in accordance with the Revolving Credit Facility). 2.500% Senior Unsecured Notes Due 2031 On July 1, 2021, we issued $ 750.0 million aggregate principal amount of 2.500% senior notes due July 2031 (the 2.500 % Senior Unsecured Notes). The 2.500% Senior Unsecured Notes are senior unsecured obligations of the Company and are not guaranteed by any of our subsidiaries. The 2.500% Senior Unsecured Notes were issued net of original issue discount of $ 6.3 million and have an effective interest rate of approximately 2.6 %. The original issue discount is being amortized by the effective interest method over the ten-year term of the notes. The 2.500% Senior Unsecured Notes are redeemable prior to April 1, 2031 at a redemption price equal to 100 % of the aggregate principal amount of the 2.500% Senior Unsecured Notes being redeemed, plus the present value of remaining scheduled payments of principal and interest from the applicable redemption date to April 1, 2031, discounted to the redemption date on a semi-annual basis at the Treasury rate plus 20 basis points. The 2.500% Senior Unsecured Notes are redeemable on or after April 1, 2031 at a redemption price equal to 100 % of the aggregate principal amount of the 2.500 % Senior Unsecured Notes being redeemed, plus accrued and unpaid interest to, but excluding, the applicable redemption date. If we experience certain change of control triggering events, we would be required to offer to repurchase the 2.500% Senior Unsecured Notes at a purchase price equal to 101 % of the aggregate principal amount of the 2.500% Senior Unsecured Notes being repurchased, plus accrued and unpaid interest to, but excluding, the applicable redemption date. The indenture governing the 2.500% Senior Unsecured Notes contains certain covenants that limit our 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, and provides for certain events of default that, if any occurred, would permit or require the principal of and accrued interest on the 2.500% Senior Unsecured Notes to become or be declared due and payable. Retirement of Debt In connection with the issuance of the 2.500% Senior Unsecured Notes on July 1, 2021 , we repaid all outstanding amounts under and terminated our $ 665.0 million term loan credit agreement (the Term Loan Credit Agreement). The Term Loan Credit Agreement was used to pay a portion of the purchase price for the Kosmos Acquisition and fees and expenses incurred in connection with the Kosmos Acquisition in March 2020 . Additionally, on July 19, 2021 (the first business day following the redemption date), we redeemed and paid in full all outstanding amounts due under the $ 350.0 million aggregate principal amount of 4.500% senior notes (4.500% Senior Unsecured Notes) due August 2026 , using proceeds from the 2.500% Senior Unsecured Notes, the Revolving Credit Facility and cash on hand. The 4.500% Senior Unsecured Notes redemption price included all of the outstanding principal and accrued interest through the redemption date of July 17, 2021 , as well as an early termination premium of approximately $ 8.4 million. In connection with the termination and repayment of the Term Loan Facility and the redemption of the 4.500% Senior Unsecured Notes, we expensed approximately $ 6.1 million of related debt issuance costs in July 2021.

Segment Reporting [Abstract]
SEGMENT INFORMATION	(N) 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. Our business is organized into two sectors within which there are four 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. Our primary products are commodities that are essential in commercial and residential construction; public construction projects; and projects to build, expand, and repair roads and highways. Demand for our products is generally cyclical and seasonal, depending on economic and geographic conditions. We distribute our products throughout most of the United States, except the Northeast, which provides us with regional economic diversification. 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 that 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). We operate eight cement plants (one of which is operated through a joint venture located in Buda, Texas), one slag grinding facility, and 30 cement distribution terminals. Our cement companies focus on the U.S. heartland and operate as an integrated network selling product primarily in California, Colorado, Illinois, Indiana, Iowa, Kansas, Kentucky, Missouri, Nebraska, Nevada, Ohio, Oklahoma, Tennessee, and Texas. We operate 30 readymix concrete batch plants and five aggregates processing plants in markets that are complementary to our cement network. We operate five gypsum wallboard plants and a recycled paperboard mill. We distribute gypsum wallboard and recycled paperboard throughout the continental U.S., with the exception of the Northeast. We account for intersegment sales at market prices. For segment reporting purposes only, we proportionately consolidate our 50 % share of the Joint Venture Revenue and Operating Earnings, consistent with the way management reports the segments within the Company for making operating decisions and assessing performance. The following table sets forth certain financial information relating to our operations by segment.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	(P) 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, auto, and general liability self-insurance. At December 31 , 2022, we had contingent liabilities under these outstanding letters of credit of approximately $ 6.4 million. In the ordinary course of business, we execute contracts involving indemnifications that are both standard in the industry and specific to a transaction, such as the 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; and 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 with unaffiliated third parties. We are currently contingently liable for performance under $ 26.9 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. No material claims have been made at this time against these financial instruments.
