Significant Accounting Policies | (A) Significant Accounting Policies Basis of Presentation – The consolidated financial statements include the accounts of Eagle Materials Inc. and its majority-owned subsidiaries (“EXP” or the “Company”), which may be referred to as “our”, “we”, or “us”. All intercompany balances and transactions have been eliminated. EXP is a holding company whose assets consist of its investments in its subsidiaries, joint venture, intercompany balances and holdings of cash and cash equivalents. The businesses of the consolidated group are conducted through EXP’s subsidiaries. The Company conducts one of its cement plant operations through a joint venture, Texas Lehigh Cement Company L.P., which is located in Buda, Texas (the “Joint Venture”). Investments in the Joint Venture and affiliated companies owned 50% or less are accounted for using the equity method of accounting. The Equity in Earnings of Unconsolidated Joint Venture has been included for the same period as our March 31 year end. The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. 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. We evaluated all events or transactions that occurred after March 31, 2013 through the filing of these financial statements. Reclassifications – Certain prior period reclassifications have been made to conform to the current period presentation. Cash and Cash Equivalents – Cash equivalents include short-term, highly liquid investments with original maturities of three months or less and are recorded at cost, which approximates market value. Accounts and Notes Receivable – Accounts and notes receivable have been shown net of the allowance for doubtful accounts of $5.1 million and $5.0 million at March 31, 2013 and 2012, 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 March 31, 2013, of which approximately $1.7 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 4.3%, which will vary based on changes to LIBOR. Remaining unpaid amounts, plus accrued interest, mature on various dates between 2013 and 2017. The notes are collateralized by certain assets of the borrowers, namely property and equipment. We monitor the credit risk of each borrower by focusing on the timeliness of payments, review of credit history and credit metrics and interaction with the borrowers. At March 31, 2013 and 2012, approximately $0.6 million of our allowance for doubtful accounts is related to our notes receivable.
Inventories – Inventories are stated at the lower of average cost (including applicable material, labor, depreciation, and plant overhead) or market. Inventories consist of the following:
Property, Plant and Equipment – Property, plant and equipment are stated at cost. Major renewals and improvements are capitalized and depreciated. Annual maintenance is expensed as incurred. Depreciation is provided on a straight-line basis over the estimated useful lives of depreciable assets and totaled $55.1 million, $48.9 million and $48.2 million for the years ended March 31, 2013, 2012 and 2011, respectively. Raw material deposits are depleted as such deposits are extracted for production utilizing the units-of-production method. Costs and accumulated depreciation applicable to assets retired or sold are eliminated from the accounts and any resulting gains or losses are recognized at such time. The estimated lives of the related assets are as follows:
We periodically evaluate whether current events or circumstances indicate that the carrying value of our depreciable assets may not be recoverable. At March 31, 2013 and 2012, management believes no events or circumstances indicate that the carrying value may not be recoverable. We temporarily idled our gypsum manufacturing facility in Bernalillo, N.M. beginning in December 2009, due to cyclical low gypsum wallboard demand. The carrying value of the Bernalillo plant and equipment at March 31, 2013 was $3.1 million and $2.9 million, respectively and we continue to depreciate the assets over their estimated useful life. We currently have a strong market position in New Mexico, and our Albuquerque gypsum wallboard facility is operating at close to capacity. We plan on resuming manufacturing at the Bernalillo facility in the future when demand for our products improves. Costs of maintaining the facility during the idling are not significant, and the facility was generating positive cash flow prior to being idled; therefore, we have determined that the value of the plant and equipment is not impaired. We are not currently considering the permanent closure of the Bernalillo facility. Any decision to permanently close Bernalillo would be the result of future changes in the building materials industry in the southwest United States and Rocky Mountain region, including changes in the production capacity or operations of our competitors, demand for gypsum wallboard or general macro-economic conditions, which we do not foresee at the present time. If we were to permanently close the Bernalillo facility, or if our expectations as to its use changed such that we project the future undiscounted cash flows from its operations would be insufficient to recover its carrying value due to the factors described above, or for any other reason, we would recognize impairment at that time.
Impairment or Disposal of Long-Lived Assets – We evaluate the recoverability of our long-lived assets and certain identifiable intangibles, such as permits and customer contracts, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets, such as plants, buildings and machinery and equipment, including mining assets, is measured by comparing the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. Such evaluations for impairment are significantly impacted by estimates of future prices for our products, capital needs, economic trends in the construction sector and other factors. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds their fair value. Assets to be disposed of by sale are reflected at the lower of their carrying amount or fair value less cost to sell. Goodwill and Intangible Assets – Goodwill. Goodwill is subject to at least an annual assessment for impairment by applying a fair-value-based test. We have elected to test for goodwill impairment in the fourth quarter of each fiscal year. The goodwill impairment test is a two-step process, which requires us to make judgments in determining what assumptions to use in the calculation. The first step of the process consists of estimating the fair value of each reporting unit based on a discounted cash flow model using revenues and profit forecasts and comparing those estimated fair values with the carrying value; a second step is performed, if necessary, to compute the amount of the impairment by determining an “implied fair value” of goodwill. Similar to the review for impairment of other long-lived assets, evaluations for impairment are significantly impacted by estimates of future prices for our products, capital needs, economic trends and other factors.
Amortization expense of intangibles was $1.0 million, $0.6 million and $0.6 million for the years ended March 31, 2013, 2012 and 2011, respectively. Amortization expense is expected to be approximately $2.0 million per year for fiscal years 2014, 2015 and 2016, $1.7 million for fiscal year 2017 and $1.0 million for fiscal year 2018. Other Assets – Other assets are primarily composed of loan fees and financing costs, deferred expenses, and deposits.
Income Taxes – Income taxes are accounted for using the asset and liability method. Deferred taxes are recognized for the tax consequences of temporary differences by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. In addition, we recognize future tax benefits to the extent that such benefits are more likely than not to be realized. Stock Repurchases – Our Board of Directors has approved the repurchase of a cumulative total of 31,610,605 shares, of which approximately 717,300 shares remain available for repurchase at March 31, 2013. We did not repurchase any shares in the open market during the years ended March 31, 2013, 2012 and 2011. Revenue Recognition – Revenue from the sale of cement, gypsum wallboard, paperboard, concrete and aggregates is recognized when title and ownership are transferred upon shipment to the customer. Fees for shipping and handling are recorded as revenue, while costs incurred for shipping and handling are recorded as expenses. We classify amounts billed to customers for freight as revenues and freight costs as cost of goods sold, respectively, in the Consolidated Statements of Earnings. Approximately $83.2 million, $66.0 million and $62.0 million were classified as cost of goods sold in the years ended March 31, 2013, 2012 and 2011, respectively. Other 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 which have not been allocated to a business segment. Comprehensive Income/Losses – As of March 31, 2013, we have an accumulated other comprehensive loss of $7.0 million, which is net of income taxes of $3.8 million, in connection with recognizing the difference between the fair value of the pension assets and the projected benefit obligation. Consolidated Cash Flows – Supplemental Disclosures – Interest payments made during the years ended March 31, 2013, 2012 and 2011 were $14.6 million, $18.8 million and $18.1 million, respectively. We made net payments of $14.8 million and $61.9 million for federal and state income taxes in the years ended March 31, 2013 and 2011, respectively, and received a net refund of $8.0 million in the year ended March 31, 2012. Certain deposits made with the IRS in fiscal year 2010 were converted to payments in fiscal 2011, and are shown as payments in fiscal 2011. Statements of Consolidated Earnings – Supplemental Disclosures – Maintenance and repair expenses are included in each segment’s costs and expenses. We incurred $61.3 million, $37.6 million and $34.5 million in the years ended March 31, 2013, 2012 and 2011, respectively, which is included in Cost of Goods Sold on the Consolidated Statement of Earnings.
Selling, general and administrative expenses of the operating units are included in Cost of Goods Sold on the Consolidated Statements of Earnings. Corporate general and administrative (“G&A”) expenses include administration, financial, legal, employee benefits and other corporate activities and are shown separately in the consolidated statements of earnings. Corporate G&A also includes stock compensation expense. See Note (J) for more information. Total selling, general and administrative expenses for each of the periods are summarized as follows:
During fiscal 2012, we repurchased $88.1 million of our senior debt at a premium, which was recorded inclusive of transaction costs. The amount of the premium plus transaction costs was $2.1 million. Earnings Per Share –
There were 1,082,380, 2,773,279 and 1,904,637 stock options at an average exercise price of $39.65 per share, $42.17 per share and $44.45 per share that were excluded from the computation of diluted earnings per share for the years ended March 31, 2013, 2012 and 2011, respectively, because such inclusion would have been anti-dilutive. Fair Value Measures Certain assets and liabilities are required to be recorded or disclosed at fair value. The estimated fair values of those assets and liabilities have been determined using market information and valuation methodologies. Changes in assumptions or estimation methods could affect the fair value estimates; however, we do not believe any such changes would have a material impact on our financial condition, results of operations or cash flows. There are three levels of inputs that may be used to measure fair value: Level 1 – Quoted prices for identical assets and liabilities in active markets; Level 2 – Quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data; and Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.
New Accounting Standards – In June 2011, the FASB issued ASU 2011-05, Presentation of Comprehensive Income, which requires comprehensive income to be reported in either a single statement of comprehensive income or in separate, consecutive statements reporting net income and other comprehensive income. In December 2011, the FASB issued ASU 2011-12 which deferred the effective date of the requirement in ASU 2011-05 to present separate line items on the income statement for reclassification adjustments of items out of accumulated other comprehensive income into net income. Retrospective application is required and both ASUs are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. We adopted this Standard during our fiscal first quarter ended June 30, 2012. Acquisition, Litigation and Other Expense Acquisition and litigation expense consists primarily of expenses incurred during our acquisition and significant legal expenses incurred during litigation, primarily litigation involving an ongoing lawsuit against the Internal Revenue Service (“IRS”), and an adverse arbitration ruling in fiscal 2012. See Note (I), Commitments and Contingencies, for more information about the outstanding lawsuit with the IRS and the results of the arbitration ruling. During February 2011, we determined that we would not move forward with the planned expansion of our Nevada Cement facility. As a result of this decision, we wrote-off approximately $8.9 million related to the planned expansion during fiscal 2011. The remaining expense in 2011 consists of the write-down of unused aggregate equipment in our Texas operation and other miscellaneous write-downs. |

Acquisition | (B) Acquisition On November 30, 2012, the Company completed the acquisition (the “Acquisition”) of certain assets of Lafarge North America Inc. (“Lafarge North America” or “the Sellers”). The Acquisition allows us to expand the scope of our cement business in a geographic area that is complementary to, but does not overlap with, our existing cement business. The Acquisition also further positions the Company near energy growth markets where there is growing demand for our specialty oil well cement and other related products. The assets acquired by us in the Acquisition were used by the Sellers in connection with the business (the “Recently Acquired Assets”) of producing, marketing and selling portland cement and concrete in Kansas, Missouri and Oklahoma, and include the following:
In most cases, we acquired ownership of these assets from the Sellers. However, the cement plant located in Sugar Creek, Missouri was leased by the Sellers pursuant to a long-term lease containing a purchase option exercisable by payment of a nominal fee. This lease, including the purchase option, was transferred to us at the closing of the Acquisition. In addition, we assumed certain liabilities in the Acquisition, including accounts payable, contractual obligations, reclamation obligations and other liabilities related to the Recently Acquired Assets. Purchase Price: The purchase price (the “Purchase Price”) of the Acquisition was $453.4 million, and is subject to adjustment to reflect actual working capital acquired at the closing. We funded the payment of the Purchase Price and expenses incurred in connection with the Acquisition through a combination of borrowings under our bank credit facility and the proceeds from our issuance of common stock, which was completed on October 3, 2012.
Recording of assets acquired and liabilities assumed: The Acquisition has been accounted for using the acquisition method of accounting which requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. We engaged a third-party to perform a valuation to support our estimate of the fair value of certain assets acquired in the Acquisition. The working capital amounts paid at the closing are subject to certain changes to reflect actual working capital. Any changes to the working capital amounts will affect certain of the amounts set forth in the table below, including the total purchase price. The preparation of the valuation of the assets acquired and liabilities assumed in the Acquisition requires the use of significant assumptions and estimates. Critical estimates include, but are not limited to, future expected cash flows, including projected revenues and expenses, and applicable discount rates. These estimates are based on assumptions that we believe to be reasonable. However, actual results may differ from these estimates. Under the acquisition method of accounting, the total purchase price was allocated to the net tangible and intangible assets and assumed liabilities based on their estimated fair values at the acquisition date. Based on our estimate of the fair value of tangible and intangible assets acquired and liabilities assumed the purchase price is allocated as follows:
Intangible Assets: The following table is a summary of the fair value estimates of the identifiable intangible assets (in thousands) and their weighted-average useful lives:
Actual and pro forma impact of the Acquisition: The following table presents the net sales and operating income of the Recently Acquired Assets that has been included in our consolidated statement of earnings from November 30, 2012 through the end of the fiscal year:
The unaudited pro forma results presented below include the effects of the Acquisition as if it had been consummated as of April 1, 2011. The pro forma results include the amortization associated with an estimate for acquired intangible assets and interest expense associated with debt used to fund the Acquisition, depreciation from the fair value adjustments for property and equipment, and the impact on earnings per share of the issuance of common stock in connection with the Acquisition. To better reflect the combined operating results, material nonrecurring charges directly related to the Acquisition of $6.1 million have been excluded from pro forma net income for the twelve month periods ended March 31, 2013 and 2012.
The pro forma results do not include any anticipated synergies or other expected benefits of the Acquisition. Accordingly, the unaudited pro forma results are not necessarily indicative of either future results of operations or results that might have been achieved had the Acquisition been consummated as of April 1, 2011. |

Indebtedness | (E) Indebtedness Long-term debt consists of the following:
On December 16, 2011, we accepted for repurchase $59.1 million in aggregate principal amount of our Series 2007A Senior Notes for $60.2 million, plus accrued interest of $0.3 million, and $29.0 million in aggregate principal amount of our Series 2005A Senor Notes for $29.6 million, plus accrued interest of $0.4 million. The purchase of the Senior Notes was funded through borrowings under our Bank Credit Facility. The premium paid on these repurchases has been included in Loss on Debt Retirement in our Consolidated Statement of Earnings for the fiscal year ended March 31, 2012. The weighted-average interest rate of Senior Notes during fiscal 2013, 2012 and 2011 was 5.81%, 5.78% and 5.75%, respectively. The interest rate of the Senior Notes was 5.81% and 5.8% at March 31, 2013 and 2012, respectively. The weighted-average interest rate of bank debt borrowings during fiscal 2013, 2012 and 2011 was 2.0%, 2.6% and 1.7%, respectively. The interest rate on the bank debt was 2.0% and 2.5% at March 31, 2013 and 2012, respectively. Our maturities of long-term debt during the next five fiscal years and thereafter are as follows:
Senior Notes - We entered into a Note Purchase Agreement on November 15, 2005 (the “2005 Note Purchase Agreement”) related to our sale of $200 million of senior, unsecured notes, designated as Series 2005A Senior Notes (the “Series 2005A Senior Notes”) in a private placement transaction. The Series 2005A Senior Notes, which are guaranteed by substantially all of our subsidiaries, were sold at par and issued in three tranches on November 15, 2005. Since entering into the 2005 Note Purchase Agreement, we have repurchased $81.1 million in principal of the Series 2005A Senior Notes (in periods prior to the fiscal year ended March 31, 2013). During November 2012, Tranche A of the Series 2005A Senior Notes matured and we retired the remaining $4.7 million in notes from this Tranche. Following these repurchases and maturities, the amounts outstanding for each of the remaining tranches are as follows:
Interest for each tranche of Notes is payable semi-annually on May 15 and November 15 of each year until all principal is paid for the respective tranche. We also entered into an additional Note Purchase Agreement on October 2, 2007 (the “2007 Note Purchase Agreement”) related to our sale of $200 million of senior, unsecured notes, designated as Series 2007A Senior Notes (the “Series 2007A Senior Notes”) in a private placement transaction. The Series 2007A Senior Notes, which are guaranteed by substantially all of our subsidiaries, were sold at par and issued in four tranches on October 2, 2007. Since entering into the 2007 Note Purchase Agreement, we have repurchased $122.0 million in principal of the Series 2007A Senior Notes (in periods prior to the fiscal year ended March 31, 2013). Following the repurchase, the amounts outstanding for each of the four tranches are as follows:
Interest for each tranche of Notes is payable semi-annually on April 2 and October 2 of each year until all principal is paid for the respective tranche. We amended both the 2005 Note Purchase Agreement and 2007 Note Purchase Agreement (collectively, the “Note Purchase Agreements”) on September 26, 2012. The amendment to each Note Purchase Agreement, among other things, mirrors the amendments to the Credit Facility, by changing certain provisions in the negative covenants in order to allow for and facilitate the Acquisition, as well as to implement certain related changes to the financial covenants. These financial covenant changes primarily related to amending the definition of Consolidated EBITDA to allow the add-back to consolidated net income of certain transaction and other allocated overhead costs related to the Acquisition that are not expected to be incurred in the future as well as reasonably identifiable cost savings, improvements and synergies related to the purchase of the Recently Acquired Assets. Our obligations under the 2005 Note Purchase Agreement and the 2007 Note Purchase Agreement (collectively referred to as the “Note Purchase Agreements”) and the Series 2005A Senior Notes and the Series 2007A Senior Notes (collectively referred to as “the Senior Notes”) are equal in right of payment with all other senior, unsecured debt of the Company, including our debt under the Credit Facility. The Note Purchase Agreements contain customary restrictive covenants, including 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, as well as certain cross covenants with the Credit Facility. We were in compliance with all financial ratios and tests at March 31, 2013 and throughout the fiscal year. 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 Note Purchase Agreements) on the Senior Notes and the other payment and performance obligations of the Company contained in the Senior Notes and in the Note Purchase Agreements. 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 Senior 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 payments of interest and principal of the Senior Notes being prepaid at a discount rate equal to the sum of 50 basis points and the yield to maturity of U.S. treasury securities having a maturity equal to the remaining average life of the Senior Notes being prepaid. Bank Debt - On December 16, 2010, we entered into a $300.0 million revolving Credit Facility, which was amended on September 26, 2012 and is scheduled to expire on December 16, 2015. The recent amendment to the Credit Facility increased available revolving borrowings from $300.0 million to $400.0 million (including an increase in the swingline loan sublimit from $15.0 million to $25.0 million) and changed certain provisions in the negative covenants in order to allow for or facilitate the Acquisition, as well as to implement certain related changes to the financial covenants. These financial covenant changes primarily related to amending the definition of Consolidated EBITDA to allow the add-back to consolidated net income of certain transaction and other allocated overhead costs related to the Acquisition that are not expected to be incurred in the future. Borrowings under the Credit Facility are guaranteed by substantially all of the Company’s subsidiaries. At the option of the Company, outstanding principal amounts on the Credit Facility bear interest at a variable rate equal to (i) 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%, per annum plus an agreed margin (ranging from 0 to 125 basis points). Interest payments are payable, in the case of loans bearing interest at a rate based on the federal funds rate, quarterly, or in the case of loans bearing interest at a rate based on LIBOR, at the end of the LIBOR advance periods, which can be up to a period of six months at the option of the Company. The Company is also required to pay a commitment fee on unused available borrowings under the Credit Facility ranging from 10 to 35 basis points depending upon our Leverage Ratio. The Credit Facility contains customary covenants that restrict our ability to incur additional debt, encumber our assets, sell assets, make or enter into certain investments, loans or guaranties and enter into sale and leaseback arrangements. The Credit Facility also requires us to maintain a consolidated indebtedness ratio (calculated as consolidated indebtedness to consolidated earnings before interest, taxes, depreciation, amortization, certain transaction-related deductions and other non-cash deductions) of 3.5:1.0 or less and an interest coverage ratio (consolidated earnings before interest, taxes, depreciation, amortization, certain transaction-related deductions and other non-cash deductions to consolidated interest expense) of at least 2.5:1.0. The Credit Facility also limits our ability to make certain restricted payments, such as paying cash dividends; however, there are several exceptions to this restriction, including: (i) the Company may pay cash dividends in an aggregate amount of up to $50.0 million each fiscal year; and (ii) the Company may make restricted payments not otherwise permitted so long as, in each case, no default would result therefrom and our consolidated funded indebtedness ratio does not exceed 3.0:1.0. We had $297.0 million of borrowings outstanding under the Credit Facility at March 31 2013. Based on our Leverage Ratio, we had $96.0 million of available borrowings, net of the outstanding letters of credit, under the Credit Facility at March 31, 2013. The Credit Facility has a $50.0 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 March 31, 2013, we had $7.1 million of letters of credit outstanding. As a result of the Acquisition, we succeeded to the leasehold interest held by Lafarge North America with respect to the cement plant located in Sugar Creek, Missouri, as well as its obligations under certain related industrial revenue bonds. In 1998, Lafarge North America had entered into a series of agreements, which were later amended in 2003, with the City of Sugar Creek, Missouri, in connection with the construction of improvements at the Sugar Creek cement plant. Under these agreements, Lafarge North America leased the Sugar Creek cement plant from the City of Sugar Creek, Missouri, which issued $150.0 million of tax-exempt and taxable industrial revenue bonds to partly finance the construction of such improvements. The lease payments due to the City of Sugar Creek under the Sugar Creek cement plant lease 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. Upon the closing of the Acquisition, funds for the retirement of $47.0 million of the industrial revenue bonds were placed into escrow by Lafarge North America, resulting in the defeasement of such bonds and leaving $103.0 million of industrial revenue bonds outstanding. The remaining $103.0 million of industrial revenue bonds held by Lafarge North America were transferred to a wholly owned subsidiary of the Company in connection with the Acquisition. Because of the defeasement described above and the fact that we are now the holder of all of the outstanding industrial revenue bonds, no debt is reflected on our financial statements in connection with our lease of the Sugar Creek cement plant. On August 31, 2011, we entered into an Uncommitted Master Shelf Agreement (the “Shelf Agreement”) with John Hancock Life Insurance Company (U.S.A.) (“Hancock”). The Shelf Agreement provides the terms under which the Company may offer up to $75 million of its senior unsecured notes for purchase by Hancock or Hancock’s affiliates that become bound by the Shelf Agreement (collectively, “Purchasers”). The Shelf Agreement does not obligate the Company to sell, or the Purchasers to buy, any such notes, and has a term of two years. We have not sold any notes pursuant to the Shelf Agreement as of March 31, 2013. |

Fair Value of Financial Instruments | (F) Fair Value of Financial Instruments The fair value of our senior notes has been estimated based upon our current incremental borrowing rates for similar types of borrowing arrangements. The fair value of our Senior Notes at March 31, 2013 is as follows:
The estimated fair value of our long-term debt was based on quoted prices of similar debt instruments with similar terms that are publicly traded (level 2 input). The carrying values of cash and cash equivalents, accounts and notes receivable, accounts payable and accrued liabilities approximate their fair values at March 31, 2013 due to the short-term maturities of these assets and liabilities. The fair value of our Credit Facility also approximates its carrying value at March 31, 2013. |

Business Segments | (G) Business Segments Operating segments are defined as components of an enterprise that engage in business activities that earn revenues, 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 operate in four business segments: Cement, Gypsum Wallboard, Recycled Paperboard, and Concrete and Aggregates, with Gypsum Wallboard and Cement being our principal lines of business. These operations are conducted in the U.S. and include the mining of limestone and the manufacture, production, distribution and sale of Portland cement (a basic construction material which is the essential binding ingredient in concrete), the mining of gypsum and 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). These products are used primarily in commercial and residential construction, public construction projects and projects to build, expand and repair roads and highways. As further discussed below, we operate six cement plants, sixteen cement distribution terminals, five gypsum wallboard plants, including the plant temporarily idled in Bernalillo, N.M., a gypsum wallboard distribution center, a recycled paperboard mill, seventeen readymix concrete batch plant locations and four aggregates processing plant locations. The principal markets for our cement products are Texas, northern Illinois (including Chicago), the central plains, the Rocky Mountains, northern Nevada, and northern California. Gypsum wallboard and recycled paperboard are distributed throughout the continental U.S. Concrete and aggregates are sold to local readymix producers and paving contractors in the Austin, Texas area and northern California. We conduct one of our six 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 revenues and operating earnings, which is 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:
Segment operating earnings, including the proportionately consolidated 50% interest in the revenues and expenses of the Joint Venture, represent revenues less direct operating expenses, segment depreciation, and segment selling, general and administrative expenses. We account for intersegment sales at market prices. Corporate assets consist primarily of cash and cash equivalents, general office assets and miscellaneous other assets.
The basis used to disclose Identifiable Assets, Capital Expenditures and Depreciation, Depletion conforms with the equity method, and is similar to how we disclose these accounts in our Consolidated Balance Sheets and Consolidated Statements of Earnings. The segment breakdown of goodwill at March 31, 2013 and 2012 is as follows:
During fiscal 2012, we provided approximately $12.0 million to our Joint Venture for its capital needs, which has been offset against distributions received from the Joint Venture during fiscal 2012 on the Consolidated Statement of Cash Flows. |

Income Taxes | (H) Income Taxes The provision for income taxes includes the following components:
The effective tax rates vary from the federal statutory rates due to the following items:
During fiscal 2012, the Federal statute of limitations for assessment for the years ended March 31, 2004, March 31, 2005 and March 31, 2006 expired. Also, we participated in amnesty programs in Arizona, Colorado and California. These events were treated as discrete items in the tax provision and a benefit totaling $2.5 million on an after-tax basis was recognized. In January 2012, we received payment of the $9.1 million owed to us by the IRS at March 31, 2012 due to carryback of net operating loss for tax purposes. The deferred income tax provision results from the following temporary differences in the recognition of revenues and expenses for tax and financial reporting purposes:
Components of deferred income taxes are as follows:
Deferred income taxes are classified in the consolidated balance sheet as follows:
Uncertain tax position – We are subject to audit examinations at federal, state and local levels by tax authorities in those jurisdictions who may challenge the treatment or reporting of any return item. The tax matters challenged by the tax authorities are typically complex; therefore, the ultimate outcome of these challenges is subject to uncertainty.
Reconciliation of the consolidated liability for gross unrecognized tax benefits, excluding interest, from April 1, 2010 to March 31, 2013, is as follows:
We recognize penalties associated with uncertain tax positions as part of the tax provision, while interest associated with uncertain tax positions is included in interest expense. The following is a summary of the amounts of interest and penalties recognized in relation to our uncertain tax position:
The amount of net unrecognized tax benefits that, if recognized, would affect the effective tax rate at March 31, 2013 was $26.1 million, of which $14.5 million has been deducted on our tax returns. In May 2011, we filed a lawsuit against the Internal Revenue Service (“IRS”) in Federal District Court to recover all of the amounts paid to the IRS with respect to our uncertain tax position for 2001 through 2006. If we were to prevail, we would receive a refund of up to $106.6 million related to federal and state taxes, interest and penalties paid since fiscal 2008 (see Note (H) for more information). Any refund of income taxes or penalties received from the IRS would be recorded as a tax benefit and impact our effective tax rate. Any refund of interest would reduce future interest expense. Additionally, we would reduce other long-term liabilities by $29.9 million, which is comprised of $26.1 million related to our unrecognized tax benefit, including penalties, and $3.8 for accrued interest on the uncertain tax position, which would also impact our tax provision. In March 2013, the IRS agreed to suspend the audit for tax years 2007 through 2011 pending the outcome of our case before the Federal District Court. We currently are unable to estimate the range of possible increase or decrease in uncertain tax positions that may occur within the next twelve months resulting from the eventual outcome of the years currently under audit or appeal, and therefore cannot anticipate whether such outcome will result in a material change to our financial position ,results of operations or cash flows. |

Commitments and Contingencies | (I) Commitments and Contingencies Our operations and properties are subject to extensive and changing federal, state and local laws, regulations and ordinances governing the protection of the environment, as well as laws relating to worker health and workplace safety. We carefully consider the requirements mandated by such laws and regulations and have procedures in place at all of our operating units to monitor compliance. Any matters which are identified as potential exposures under these laws and regulations are carefully reviewed by management to determine our potential liability. Although management is not aware of any exposures which require an accrual under generally accepted accounting principles, there can be no assurance that prior or future operations will not ultimately result in violations, claims or other liabilities associated with these regulations. We have certain deductible limits under our workers’ compensation and liability insurance policies for which reserves are established based on the estimated costs of known and anticipated claims. We have entered into standby letter of credit agreements to secure funding obligations on retentions relating to workers’ compensation and auto and general liability self-insurance. At March 31, 2013, we had contingent liabilities under these outstanding letters of credit of approximately $7.1 million.
The following table compares insurance accruals and payments for our operations:
We are currently contingently liable for performance under $13.6 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. Outstanding Lawsuit against the IRS As described in more detail below, the IRS has challenged certain depreciation deductions claimed by us with respect to assets (the “Republic Assets”) acquired by us from Republic Group LLC in a transaction completed in November 2000 (the “Republic Assets Acquisition”). We are engaged in administrative and judicial proceedings seeking to establish our right to claim these deductions. The IRS has completed its examinations of our federal income tax returns for fiscal years ended March 31, 2001 through March 31, 2010. The IRS issued Exam Reports and Notices of Proposed Adjustment on November 9, 2007 for the examination of the 2001, 2002 and 2003 tax years, and on February 5, 2010 for the examination of the 2004, 2005 and 2006 tax years, in which it denied certain depreciation deductions claimed by us with respect to assets acquired from Republic Group LLC in November 2000 (the “Republic Assets”). In addition, on October 5, 2012, the IRS issued a 30-day letter related to the examination of the tax returns for fiscal years ended March 31, 2007 through March 31, 2010, denying certain depreciation deductions claimed by us with respect to the Republic Assets, similar to the actions taken by the IRS for our tax years ended March 31, 2001 through March 31, 2006, described above. In June 2010, we received a Notice of Deficiency (“Notice”) of $71.5 million of taxes and penalties for the fiscal years ended March 31, 2001 through 2006, inclusive, related to the IRS audit of the Republic Asset Acquisition. The Notice was in substantial agreement with our financial accruals, including interest. The final amount related to the Notice, including interest, was approximately $97.9 million, of which $75 million had previously been deposited with the IRS. We deposited the remaining amounts with the IRS in July 2010 and asked the IRS to apply all $97.9 million of deposits to the payment of the tax, penalties and interest. Refund claims were filed with the IRS in October 2010 to recover all $97.9 million, plus interest. The IRS has denied our refund request and we filed a lawsuit in May 2011 in Federal District Court to recover the requested refunds. With respect to the tax returns for the fiscal years ended March 31, 2007 through March 31, 2010, the IRS has issued an assessment of approximately $8.1 million of income tax and approximately $1.9 million in penalties relating to the acquisition of the Republic Assets. In addition, we estimate that interest of approximately $1.9 million has accrued on these amounts as of March 31, 2013. These amounts have been fully accrued in our financial statements at March 31, 2013. The amounts accrued have been treated as unrecognized tax liabilities and are included in Other Long Term Liabilities on our Consolidated Balance Sheet at March 31, 2013 and 2012. On October 31, 2012, we appealed the findings of the examiner to the IRS Appeals Office, contesting the assessment of tax, penalties and interest for fiscal years ended March 31, 2007 through March 31, 2010. In March 2013, the IRS agreed to suspend the audit for tax years 2007 through 2011 pending the outcome of our case in Federal District Court.
In the event we reach a settlement through negotiation or in the courts, we will reverse any amounts in excess of the settlement through the Consolidated Statement of Earnings. At this time, we are unable to predict with certainty the ultimate outcome or how much of the amounts paid for tax, interest, and penalties to the IRS and state taxing authorities will be recovered, if any. We do not expect these issues to be resolved within the next 12 months. Domestic Wallboard Antitrust Litigation Since late December 2012, several purported class action lawsuits have been filed against the Company’s subsidiary, American Gypsum Company LLC (“American Gypsum”), alleging that American Gypsum conspired with other wallboard manufacturers 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. The complaints allege that the defendant wallboard manufacturers conspired to increase prices through the announcement and implementation of coordinated price increases, output restrictions, and other restraints of trade, including the elimination of individual “job quote” pricing. In addition to American Gypsum, the defendants in these lawsuits include CertainTeed Corp., USG Corporation, New NGC, Inc., Lafarge North America, Georgia-Pacific LLC, Temple Inland Inc. and PABCO Building Products LLC. The plaintiffs in these class action lawsuits bring claims on behalf of purported classes of direct or indirect purchasers of wallboard during various periods from 2008 to the present for unspecified monetary damage (including treble damages) and in some cases injunctive relief in various United States district courts, including the Eastern District of Pennsylvania, Western District of North Carolina, North Carolina and the Northern District of Illinois. On April 8, 2013, the Judicial Panel on Multidistrict Litigation transferred and consolidated all related cases to the Eastern District of Pennsylvania for coordinated pretrial proceedings. Limited written discovery has taken place to date. Due to the recent nature of these claims, we are unable to assess the likelihood or amount of potential loss relating to the claims, or whether such losses, if any, would have a material impact on our financial position, results of operations or cash flows. American Gypsum denies the allegations in these lawsuits and will vigorously defend itself against these claims. Arbitration Claim In June 2011, we were served with a claim for arbitration involving a contract dispute between one of our aggregates mining subsidiaries and another mining company over the right to mine certain areas. The mining company which brought this claim mines gold in the same area in which our subsidiary mines aggregates. The dispute centered on two agreements entered into by the parties in 1989 and 1992 that address the rights and obligations of the parties with respect to the areas in which both companies mine. In the arbitration, the gold mining company claimed that our subsidiary’s operations in a limited area (which are conducted through a licensee) interfered with the gold mining company’s right under the agreements to mine gold and that the gold in that area was therefore no longer recoverable. The arbitration panel convened in November 2011 and resulting proceeding was concluded in December 2011, although the decision was not announced until January 19, 2012. The arbitration panel ruled against us and awarded $6.9 million to the other mining company plus attorneys’ fees and arbitration costs to the other party of approximately $1.2 million. All amounts were paid during February 2012. This amount, together with our legal expenses incurred defending this claim, is classified as Acquisition and Litigation Expense in our Consolidated Statements of Earnings for the fiscal year ended March 31, 2012. The ruling involves a limited area within our California aggregates deposit and is not expected to have a material adverse impact on our continuing operations in future periods. Other 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 the sale of a business. These indemnifications might include claims relating to any of the following: environmental and tax matters; intellectual property rights; governmental regulations and employment-related matters; customer, supplier, construction contractor and other commercial contractual relationships; and financial matters. While the maximum amount to which we may be exposed under such agreements cannot be estimated, it is the opinion of management that these indemnifications are not expected to have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows. We currently have no outstanding guarantees of third party debt. Our paperboard operation, Republic Paperboard Company LLC (“Republic”), is a party to a long-term variable-priced paper supply agreement with St. Gobain pursuant to which Republic is obligated to sell to St. Gobain at least 90% of the gypsum-grade recycled paperboard requirements for three of St. Gobain’s wallboard plants. This comprises approximately 15% to 20% of Republic’s current annual output of gypsum-grade recycled paperboard. We have certain forward purchase contracts, primarily for natural gas, that expire during calendar 2013. The contracts are for approximately 25% of our anticipated natural gas usage. We have certain operating leases covering manufacturing, transportation and certain other facilities and equipment. Rental expense for fiscal years 2013, 2012 and 2011 totaled $1.6 million, $1.7 million and $2.0 million, respectively. Minimum annual rental commitments as of March 31, 2013, under noncancellable leases are set forth as follows (dollars in thousands):

Stock Option Plans | (J) Stock Option Plans On January 8, 2004, our stockholders approved an incentive plan (the “Plan”) that combined and amended the two previously existing stock option plans. In August 2009, our shareholders approved an amendment to the Plan which, among other things, increased the number of shares available for award under the Plan by 3.0 million shares. Under the terms of the Plan, we can issue equity awards, including stock options, restricted stock units (“RSUs”), restricted stock and stock appreciation rights (collectively, the “Equity Awards”) to employees of the Company and members of the Board of Directors. 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 June 2012, we granted 42,336 options to members of the Board of Directors (the “Fiscal 2013 Board of Directors Grant”). Options granted under the Fiscal 2013 Board of Directors Grant vested six months after issuance, in December 2012, and can be exercised from the date of vesting until their expiration on the tenth anniversary of the date of grant. In August 2011, we granted options to members of the Board of Directors (the “Fiscal 2012 Board of Directors Grant”). Options granted under the Fiscal 2012 Board of Directors Grants vested, and can be exercised from the date of grant until their expiration at the end of ten years. In June 2012, the Compensation Committee of the Board of Directors approved an incentive equity award of an aggregate of 448,843 stock options pursuant to the Plan to certain employees that vest ratably over a three year period (the “Fiscal 2013 Employee Stock Option Grant”). The options have a term of ten years from the date of grant. In June 2011, the Compensation Committee of the Board of Directors approved an incentive equity award of an aggregate of 352,829 stock options pursuant to the Plan to certain employees that vest ratably over a three year period (the “Fiscal 2012 Employee Stock Option Grant”). The options have a term of ten years from the date of grant.
All stock options issued during fiscal 2013 and 2012 were valued at the 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 2013 and 2012 are as follows:
Stock option expense for all outstanding stock option awards was approximately $4.0 million, $1.4 million and $0.8 million, for the years ended March 31, 2013, 2012 and 2011, respectively. The expense for 2012 and 2011 reflects credits of $1.3 million and $1.1 million, respectively; resulting from our updated assessment of future compliance with performance conditions associated with certain stock option grants. At March 31, 2013, there was approximately $6.9 million of unrecognized compensation cost related to outstanding stock options which is expected to be recognized over a weighted-average period of 2.5 years. The following table represents stock option activity for the years presented:
The following table summarizes information about stock options outstanding at March 31, 2013:
At March 31, 2013, the aggregate intrinsic value for outstanding and exercisable options was approximately $87.0 million and $36.5 million, respectively. The total intrinsic value of options exercised during the fiscal year ended March 31, 2013 was approximately $19.9 million. Restricted Stock Units. Expense related to RSUs was approximately $1.6 million, $1.5 million and $1.6 million in fiscal years ended March 31, 2013, 2012 and 2011, respectively. At March 31, 2013, there were approximately 28,000 unvested RSUs, with approximately $0.1 million of unearned compensation, net of estimated forfeitures, which will be recognized over a weighted-average period of 3.0 years.
Restricted Stock. In June 2012, the Compensation Committee also approved the granting of an aggregate of 57,443 shares of restricted stock to certain key employees at both the corporate and subsidiary level (the “Fiscal 2013 Employee Restricted Share Award”) that would be earned if our ten year average return on equity is at least 15% at March 31, 2013. If the performance criterion were not met, all of the shares would be forfeited. The Compensation Committee has certified that the performance criterion was met at March 31, 2013; therefore, all shares were earned. Restriction on the shares will lapse ratably over five years, with the first fifth lapsing on June 19, 2013, and the remaining restrictions lapsing on March 31, 2014 through 2017. In June 2011, the Compensation Committee approved the granting of an aggregate of 412,164 shares of restricted stock to certain key employees at both the corporate and subsidiary level that would be earned if our ten year average return on invested capital exceeded 12% at March 31, 2012. If the performance criterion were not met, all shares would have been forfeited. The Compensation Committee has certified that the performance criterion had been met at March 31, 2012; therefore, all shares were earned. Restrictions on the shares will lapse ratably over five years, with the remaining restrictions lapsing on March 31, 2014 through 2016. In June 2012, we granted 16,251 shares of restricted stock to members of the Board of Directors (the “Board of Directors Fiscal 2013 Restricted Stock Award”). Awards issued under the Board of Directors Fiscal 2013 Restricted Stock Award were earned in December 2012 but the restrictions on the shares will not lapse until the retirement of the director from the Board of Directors, or earlier under such circumstances as are approved by the Compensation Committee. Expense related to restricted shares was $3.4 million, $2.6 million and $1.0 million in fiscal years ended March 31, 2013, 2012 and 2011, respectively. At March 31, 2013, there were approximately 570,000 shares with remaining restrictions for which $13.3 million of unearned compensation, net of estimated forfeitures, will be recognized over a weighted-average period of 3.9 years. Shares available for future stock option, restricted stock and restricted stock unit grants were 1,302,263 at March 31, 2013. Of the available shares, up to 106,417 can be used for future restricted stock and restricted stock unit grants. |

Pension and Profit Sharing Plans | (K) Pension and Profit Sharing Plans We have several defined benefit and defined contribution retirement plans which together cover substantially all of our employees. Benefits paid under the defined benefit plans covering certain hourly employees are based on years of service and the employee’s qualifying compensation over the last few years of employment. Our funding policy is to generally contribute amounts that are deductible for income tax purposes. The annual measurement date is March 31 for the benefit obligations, fair value of plan assets and the funded status of the defined benefit plans.
The following table provides a reconciliation of the obligations and fair values of plan assets for all of our defined benefit plans over the two year period ended March 31, 2013 and a statement of the funded status as of March 31, 2013 and 2012:
Information for pension plans with an accumulated benefit obligation in excess of plan assets:
Net periodic pension cost for the fiscal years ended March 31, 2013, 2012 and 2011, included the following components:
Expected benefit payments over the next five years, and the following five years under the pension plans are expected to be as follows (in thousands):
The following table sets forth the assumptions used in the actuarial calculations of the present value of net periodic benefit cost and benefit obligations:
The expected long-term rate of return on plan assets is an assumption reflecting the anticipated weighted-average rate of earnings on the portfolio over the long-term. To arrive at this rate, we developed estimates of the key components underlying capital asset returns including: market-based estimates of inflation, real risk-free rates of return, yield curve structure, credit risk premiums and equity risk premiums. As appropriate, these components were used to develop benchmark estimates of the expected long-term management approach employed by us, and a return premium was added to the weighted-average benchmark portfolio return. The pension plans’ approximate weighted-average asset allocation at March 31, 2013 and 2012 and the range of target allocation are as follows:
Our pension investment strategies have been developed as part of a comprehensive asset/liability management process that considers the interaction between both the assets and liabilities of the plan. These strategies consider not only the expected risk and returns on plan assets, but also the detailed actuarial projections of liabilities as well as plan-level objectives such as projected contributions, expense and funded status. The principal pension investment strategies include asset allocation and active asset management. The range of target asset allocations have been determined after giving consideration to the expected returns of each asset class, the expected variability or volatility of the asset class returns over time, and the complementary nature or correlation of the asset classes within the portfolio. We also employ an active management approach for the portfolio. Each asset class is managed by one or more external money managers with the objective of generating returns, net of management fees that exceed market-based benchmarks. None of the plans hold any EXP stock.
Based on our current actuarial estimates, we anticipate making contributions ranging from approximately $0.5 million to $1.0 million to our defined benefit plans for fiscal year 2014. The fair values of our defined benefit plans’ consolidated assets by category as of March 31, 2013 were as follows:
The fair values of our defined benefit plans’ consolidated assets were determined using the fair value hierarchy of inputs described in Note (A). The fair values by category of inputs as of March 31, 2013 were as follows:
The fair values by category of inputs as of March 31, 2012 were as follows:
Equity securities consist of funds that are maintained by an investment manager and are primarily invested in indexes. The remaining funds, excluding cash, primarily consist of investments in institutional funds. We also provide a profit sharing plan, which covers substantially all salaried and certain hourly employees. The profit sharing plan is a defined contribution plan funded by employer discretionary contributions and also allows employees to contribute on an after-tax basis up to 10% of their base annual salary. Employees are fully vested to the extent of their contributions at all times. Employees become fully vested in our contributions over a seven year period for contributions made prior to 2007, and over a six year period for contributions made beginning in 2007. Costs relating to the employer discretionary contributions for our contribution plan totaled $3.3 million, $2.5 million and $2.5 million in fiscal years 2013, 2012 and 2011, respectively. Employees who became employed by us as a result of a previous transaction are provided benefits substantially comparable to those provided under the seller’s welfare plans. These welfare plans included the seller’s 401(k) plan which included employer matching percentages. As a result, we made matching contributions to its 401(k) plan totaling $0.1 million for these employees during each of the fiscal years 2013, 2012 and 2011. As part of the Acquisition, we became party to certain multi-employer pension plans. Approximately sixty of our employees belong to five different multi-employer plans. The collective bargaining agreements for the employees who participate in the multi-employer plans expire between June 2014 and March 2017. Our expense related to these plans was approximately $0.2 million during the fiscal year ended March 31, 2013. We anticipate the total expense in fiscal 2014 related to these plans will be approximately $0.7 million. |

Net Interest Expense | (L) Net Interest Expense The following components are included in interest expense, net:
Interest income includes interest on investments of excess cash. Components of interest expense include interest associated with the Senior Notes, Credit Facility and commitment fees based on the unused portion of the Credit Facility. Other expenses include amortization of debt issuance costs, and bank credit facility costs. Interest expense (income) – IRS relates to interest accrued on our unrecognized tax benefits, primarily related to the Republic Asset Acquisition. During fiscal 2011, we paid or applied cash deposits as payments to the IRS and filed amended state tax returns and made payments for the tax years 2001 through 2006, resulting in an adjustment of previously accrued interest expense of approximately $2.8 million. During fiscal 2012, we reversed previously accrued interest expense for certain matters for which the statute of limitations had expired. |

Stockholders' Equity | (M) Stockholders’ Equity On January 8, 2004, our stockholders approved an amendment to our certificate of incorporation to increase the authorized number of shares of capital stock that we may issue from 50,000,000 shares of common stock and 2,000,000 shares of preferred stock to 100,000,000 shares of common stock and 5,000,000 shares of preferred stock. The amendment to the Certificate of Incorporation became effective on January 30, 2004. Our Board of Directors designated 40,000 shares of preferred stock for use in connection with the Rights Agreement discussed below. Effective February 2, 2004, we entered into a Rights Agreement as amended and restated on April 11, 2006 (as amended and restated, “Rights Agreement”) that was approved by stockholders at the Special Meeting of Stockholders held on January 8, 2004. In connection with the Rights Agreement, the Board authorized and declared a dividend of one right per share of common stock (the “Common Stock”). The Rights entitle our stockholders to purchase Common Stock (the “Rights”) in the event certain efforts are made to acquire control of the Company. There are no separate certificates or market for the Rights. The Rights are represented by and trade with our Common Stock. The Rights will separate from the Common Stock upon the earlier of: (1) a public announcement that a person has acquired beneficial ownership of shares of Common Stock representing in the aggregate 15% or more of the total number of votes entitled to be cast generally by the holders of Common Stock then outstanding, or (2) the commencement of a tender or exchange offer that would result in a person beneficially owning shares of Common Stock representing in the aggregate 15% or more of the total number of votes entitled to be cast generally by the holders of Common Stock then outstanding. Should either of these conditions be met and the Rights become exercisable, each Right will entitle the holder to buy 1/1,000th of a share of our Preferred Stock at an exercise price of $140.00. Each 1/1,000th of a share of the Preferred Stock will essentially be the economic equivalent of three shares of Common Stock. Under certain circumstances, the Rights entitle the holders to buy our stock or shares of the acquirer’s stock at a 50% discount. The Rights may be redeemed by us for $0.001 per Right at any time prior to the first public announcement of the acquisition of beneficial ownership of shares of Common Stock representing 15% or more of the total number of votes entitled to be cast generally by the holders of Common Stock then outstanding. If not redeemed, the Rights will expire on January 7, 2014. |

Basis of Presentation | Basis of Presentation – The consolidated financial statements include the accounts of Eagle Materials Inc. and its majority-owned subsidiaries (“EXP” or the “Company”), which may be referred to as “our”, “we”, or “us”. All intercompany balances and transactions have been eliminated. EXP is a holding company whose assets consist of its investments in its subsidiaries, joint venture, intercompany balances and holdings of cash and cash equivalents. The businesses of the consolidated group are conducted through EXP’s subsidiaries. The Company conducts one of its cement plant operations through a joint venture, Texas Lehigh Cement Company L.P., which is located in Buda, Texas (the “Joint Venture”). Investments in the Joint Venture and affiliated companies owned 50% or less are accounted for using the equity method of accounting. The Equity in Earnings of Unconsolidated Joint Venture has been included for the same period as our March 31 year end. The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. 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. We evaluated all events or transactions that occurred after March 31, 2013 through the filing of these financial statements. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Reclassifications | Reclassifications – Certain prior period reclassifications have been made to conform to the current period presentation. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Cash and Cash Equivalents | Cash and Cash Equivalents – Cash equivalents include short-term, highly liquid investments with original maturities of three months or less and are recorded at cost, which approximates market value. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Accounts and Notes Receivable | Accounts and Notes Receivable – Accounts and notes receivable have been shown net of the allowance for doubtful accounts of $5.1 million and $5.0 million at March 31, 2013 and 2012, 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 March 31, 2013, of which approximately $1.7 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 4.3%, which will vary based on changes to LIBOR. Remaining unpaid amounts, plus accrued interest, mature on various dates between 2013 and 2017. The notes are collateralized by certain assets of the borrowers, namely property and equipment. We monitor the credit risk of each borrower by focusing on the timeliness of payments, review of credit history and credit metrics and interaction with the borrowers. At March 31, 2013 and 2012, approximately $0.6 million of our allowance for doubtful accounts is related to our notes receivable. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Inventories | Inventories – Inventories are stated at the lower of average cost (including applicable material, labor, depreciation, and plant overhead) or market. Inventories consist of the following:
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Property, Plant and Equipment | Property, Plant and Equipment – Property, plant and equipment are stated at cost. Major renewals and improvements are capitalized and depreciated. Annual maintenance is expensed as incurred. Depreciation is provided on a straight-line basis over the estimated useful lives of depreciable assets and totaled $55.1 million, $48.9 million and $48.2 million for the years ended March 31, 2013, 2012 and 2011, respectively. Raw material deposits are depleted as such deposits are extracted for production utilizing the units-of-production method. Costs and accumulated depreciation applicable to assets retired or sold are eliminated from the accounts and any resulting gains or losses are recognized at such time. The estimated lives of the related assets are as follows:
We periodically evaluate whether current events or circumstances indicate that the carrying value of our depreciable assets may not be recoverable. At March 31, 2013 and 2012, management believes no events or circumstances indicate that the carrying value may not be recoverable. We temporarily idled our gypsum manufacturing facility in Bernalillo, N.M. beginning in December 2009, due to cyclical low gypsum wallboard demand. The carrying value of the Bernalillo plant and equipment at March 31, 2013 was $3.1 million and $2.9 million, respectively and we continue to depreciate the assets over their estimated useful life. We currently have a strong market position in New Mexico, and our Albuquerque gypsum wallboard facility is operating at close to capacity. We plan on resuming manufacturing at the Bernalillo facility in the future when demand for our products improves. Costs of maintaining the facility during the idling are not significant, and the facility was generating positive cash flow prior to being idled; therefore, we have determined that the value of the plant and equipment is not impaired. We are not currently considering the permanent closure of the Bernalillo facility. Any decision to permanently close Bernalillo would be the result of future changes in the building materials industry in the southwest United States and Rocky Mountain region, including changes in the production capacity or operations of our competitors, demand for gypsum wallboard or general macro-economic conditions, which we do not foresee at the present time. If we were to permanently close the Bernalillo facility, or if our expectations as to its use changed such that we project the future undiscounted cash flows from its operations would be insufficient to recover its carrying value due to the factors described above, or for any other reason, we would recognize impairment at that time. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Impairment or Disposal of Long-Lived Assets | Impairment or Disposal of Long-Lived Assets – We evaluate the recoverability of our long-lived assets and certain identifiable intangibles, such as permits and customer contracts, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets, such as plants, buildings and machinery and equipment, including mining assets, is measured by comparing the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. Such evaluations for impairment are significantly impacted by estimates of future prices for our products, capital needs, economic trends in the construction sector and other factors. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds their fair value. Assets to be disposed of by sale are reflected at the lower of their carrying amount or fair value less cost to sell. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Goodwill and Intangible Assets | Goodwill and Intangible Assets – Goodwill. Goodwill is subject to at least an annual assessment for impairment by applying a fair-value-based test. We have elected to test for goodwill impairment in the fourth quarter of each fiscal year. The goodwill impairment test is a two-step process, which requires us to make judgments in determining what assumptions to use in the calculation. The first step of the process consists of estimating the fair value of each reporting unit based on a discounted cash flow model using revenues and profit forecasts and comparing those estimated fair values with the carrying value; a second step is performed, if necessary, to compute the amount of the impairment by determining an “implied fair value” of goodwill. Similar to the review for impairment of other long-lived assets, evaluations for impairment are significantly impacted by estimates of future prices for our products, capital needs, economic trends and other factors.
Amortization expense of intangibles was $1.0 million, $0.6 million and $0.6 million for the years ended March 31, 2013, 2012 and 2011, respectively. Amortization expense is expected to be approximately $2.0 million per year for fiscal years 2014, 2015 and 2016, $1.7 million for fiscal year 2017 and $1.0 million for fiscal year 2018. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Other Assets | Other Assets – Other assets are primarily composed of loan fees and financing costs, deferred expenses, and deposits. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Income Taxes | Income Taxes – Income taxes are accounted for using the asset and liability method. Deferred taxes are recognized for the tax consequences of temporary differences by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. In addition, we recognize future tax benefits to the extent that such benefits are more likely than not to be realized. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Stock Repurchases | Stock Repurchases – Our Board of Directors has approved the repurchase of a cumulative total of 31,610,605 shares, of which approximately 717,300 shares remain available for repurchase at March 31, 2013. We did not repurchase any shares in the open market during the years ended March 31, 2013, 2012 and 2011. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Revenue Recognition | Revenue Recognition – Revenue from the sale of cement, gypsum wallboard, paperboard, concrete and aggregates is recognized when title and ownership are transferred upon shipment to the customer. Fees for shipping and handling are recorded as revenue, while costs incurred for shipping and handling are recorded as expenses. We classify amounts billed to customers for freight as revenues and freight costs as cost of goods sold, respectively, in the Consolidated Statements of Earnings. Approximately $83.2 million, $66.0 million and $62.0 million were classified as cost of goods sold in the years ended March 31, 2013, 2012 and 2011, respectively. Other 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 which have not been allocated to a business segment. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Comprehensive Income/Losses | Comprehensive Income/Losses – As of March 31, 2013, we have an accumulated other comprehensive loss of $7.0 million, which is net of income taxes of $3.8 million, in connection with recognizing the difference between the fair value of the pension assets and the projected benefit obligation. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Consolidated Cash Flows - Supplemental Disclosures | Consolidated Cash Flows – Supplemental Disclosures – Interest payments made during the years ended March 31, 2013, 2012 and 2011 were $14.6 million, $18.8 million and $18.1 million, respectively. We made net payments of $14.8 million and $61.9 million for federal and state income taxes in the years ended March 31, 2013 and 2011, respectively, and received a net refund of $8.0 million in the year ended March 31, 2012. Certain deposits made with the IRS in fiscal year 2010 were converted to payments in fiscal 2011, and are shown as payments in fiscal 2011. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Statements of Consolidated Earnings - Supplemental Disclosures | Statements of Consolidated Earnings – Supplemental Disclosures – Maintenance and repair expenses are included in each segment’s costs and expenses. We incurred $61.3 million, $37.6 million and $34.5 million in the years ended March 31, 2013, 2012 and 2011, respectively, which is included in Cost of Goods Sold on the Consolidated Statement of Earnings.
Selling, general and administrative expenses of the operating units are included in Cost of Goods Sold on the Consolidated Statements of Earnings. Corporate general and administrative (“G&A”) expenses include administration, financial, legal, employee benefits and other corporate activities and are shown separately in the consolidated statements of earnings. Corporate G&A also includes stock compensation expense. See Note (J) for more information. Total selling, general and administrative expenses for each of the periods are summarized as follows:
During fiscal 2012, we repurchased $88.1 million of our senior debt at a premium, which was recorded inclusive of transaction costs. The amount of the premium plus transaction costs was $2.1 million. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Earnings Per Share | Earnings Per Share –
There were 1,082,380, 2,773,279 and 1,904,637 stock options at an average exercise price of $39.65 per share, $42.17 per share and $44.45 per share that were excluded from the computation of diluted earnings per share for the years ended March 31, 2013, 2012 and 2011, respectively, because such inclusion would have been anti-dilutive. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Fair Value Measures | Fair Value Measures Certain assets and liabilities are required to be recorded or disclosed at fair value. The estimated fair values of those assets and liabilities have been determined using market information and valuation methodologies. Changes in assumptions or estimation methods could affect the fair value estimates; however, we do not believe any such changes would have a material impact on our financial condition, results of operations or cash flows. There are three levels of inputs that may be used to measure fair value: Level 1 – Quoted prices for identical assets and liabilities in active markets; Level 2 – Quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data; and Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
New Accounting Standards | New Accounting Standards – In June 2011, the FASB issued ASU 2011-05, Presentation of Comprehensive Income, which requires comprehensive income to be reported in either a single statement of comprehensive income or in separate, consecutive statements reporting net income and other comprehensive income. In December 2011, the FASB issued ASU 2011-12 which deferred the effective date of the requirement in ASU 2011-05 to present separate line items on the income statement for reclassification adjustments of items out of accumulated other comprehensive income into net income. Retrospective application is required and both ASUs are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. We adopted this Standard during our fiscal first quarter ended June 30, 2012. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Acquisition, Litigation and Other Expense | Acquisition, Litigation and Other Expense Acquisition and litigation expense consists primarily of expenses incurred during our acquisition and significant legal expenses incurred during litigation, primarily litigation involving an ongoing lawsuit against the Internal Revenue Service (“IRS”), and an adverse arbitration ruling in fiscal 2012. See Note (I), Commitments and Contingencies, for more information about the outstanding lawsuit with the IRS and the results of the arbitration ruling. During February 2011, we determined that we would not move forward with the planned expansion of our Nevada Cement facility. As a result of this decision, we wrote-off approximately $8.9 million related to the planned expansion during fiscal 2011. The remaining expense in 2011 consists of the write-down of unused aggregate equipment in our Texas operation and other miscellaneous write-downs. |
