1.	Significant Accounting Policies

Basis of Presentation

The accompanying unaudited consolidated financial statements of Martin Marietta Materials, Inc. (the “Corporation”) have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and to Article 10 of Regulation S-X. The Corporation has continued to follow the accounting policies set forth in the audited consolidated financial statements and related notes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2011, filed with the Securities and Exchange Commission on February 29, 2012. In the opinion of management, the interim financial information provided herein reflects all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of the results of operations, financial position and cash flows for the interim periods. The results of operations for the quarter and nine months ended September 30, 2012 are not indicative of the results expected for other interim periods or the full year. The balance sheet at December 31, 2011 has been derived from the audited financial statements at that date but does not include all of the information and notes required by generally accepted accounting principles for complete financial statements. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2011.

Warranties

The Corporation’s construction contracts contain warranty provisions covering defects in equipment, materials, design or workmanship that generally run from nine months to one year after project completion. Because of the nature of its projects, including contract owner inspections of the work both during construction and prior to acceptance, the Corporation has not experienced material warranty costs for these short-term warranties and therefore does not believe an accrual for these costs is necessary. Certain construction contracts carry longer warranty periods, ranging from two to ten years for which the Corporation has accrued an estimate of warranty cost. The warranty cost is estimated based on experience with the type of work and any known risks relative to the project and was not material for the three or nine months ended September 30, 2012 and 2011.

Consolidated Comprehensive Earnings/Loss and Accumulated Other Comprehensive Loss

Consolidated comprehensive earnings/loss for the Corporation consist of consolidated net earnings or loss; adjustments for the funded status of pension and postretirement benefit plans; foreign currency translation adjustments; and the amortization of the value of terminated forward starting interest rate swap agreements into interest expense.

Consolidated Comprehensive Earnings/Loss and Accumulated Other Comprehensive Loss (continued)

Effective January 1, 2012, as required by recent accounting guidance, the Corporation changed its presentation of consolidated comprehensive earnings/loss. The Corporation no longer reports total consolidated comprehensive earnings/loss and related components of other comprehensive earnings/loss in its consolidated statement of total equity. Rather, the Corporation presents total consolidated comprehensive earnings/loss in its consolidated statements of earnings and comprehensive earnings for interim periods and in separate but consecutive consolidated statements of comprehensive earnings for annual periods. Prior-year information has been recast to conform to this presentation approach.

Comprehensive earnings attributable to Martin Marietta Materials, Inc. consist of the following:

Earnings per Common Share

The numerator for basic and diluted earnings per common share is net earnings attributable to Martin Marietta Materials, Inc., reduced by dividends and undistributed earnings attributable to the Corporation’s unvested restricted stock awards and incentive stock awards. The denominator for basic earnings per common share is the weighted-average number of common shares outstanding during the period. Diluted earnings per common share are computed assuming that the weighted-average number of common shares is increased by the conversion, using the treasury stock method, of awards to be issued to employees and nonemployee members of the Corporation’s Board of Directors under certain stock-based compensation arrangements if the conversion is dilutive. The diluted per-share computations reflect a change in the number of common shares outstanding to include the number of additional shares that would have been outstanding if the potentially dilutive common shares had been issued.

The following table reconciles the numerator and denominator for basic and diluted earnings per common share:


	Three Months Ended September 30,						Nine Months Ended September 30,

2.	Discontinued Operations

Divestitures and Permanent Closures

Operations that are disposed of or permanently shut down represent discontinued operations, and, therefore, the results of their operations through the dates of disposal and any gain or loss on disposals are included in discontinued operations in the consolidated statements of earnings and comprehensive earnings. The results of operations for divestitures do not include Corporate overhead that was allocated during the periods the Corporation owned these operations.

All discontinued operations relate to the Aggregates business. Discontinued operations consist of the following:

5.	Long-Term Debt (continued)

On January 23, 2012, the Corporation repurchased $20,000,000 par value of its outstanding 6.25% Senior Notes due 2037 at 90.75. This repurchase was financed with borrowings of $18,200,000 under the Corporation’s Revolving Facility.

On April 13, 2012, the Corporation renewed its AR Credit Facility for a one-year term ending April 20, 2013.

The Credit Agreement (which consists of the Term Loan Facility and a $350,000,000 Revolving Facility) and the AR Credit Facility require the Corporation’s ratio of consolidated debt to consolidated earnings before interest, taxes, depreciation, depletion and amortization (EBITDA), as defined, for the trailing twelve month period (the “Ratio”) to not exceed 3.50x as of the end of any fiscal quarter, provided that the Corporation may exclude from the Ratio debt incurred in connection with certain acquisitions for a period of 180 days so long as the Corporation maintains specified ratings on its long-term unsecured debt and the Ratio calculated without such exclusion does not exceed 3.75x. Additionally, if no amounts are outstanding under both the Revolving Facility and the AR Credit Facility, consolidated debt, including debt guaranteed by the Corporation, may be reduced by the Corporation’s unrestricted cash and cash equivalents in excess of $50,000,000, such reduction not to exceed $200,000,000, for purposes of the covenant calculation.

During the first quarter of 2012, the Corporation amended the Ratio to ensure that the impact of business development costs and the seasonal working capital requirements of the Corporation’s acquired Colorado operations did not impair liquidity available under the Corporation’s Credit Agreement and AR Credit Facility. The amendment temporarily increased the maximum Ratio to 3.75x at September 30, 2012. The Corporation was in compliance with this Ratio at September 30, 2012.

In order to provide incremental liquidity cushion, on October 17, 2012, the Corporation amended the Ratio to maintain the maximum Ratio of 3.75x for the December 31, 2012, March 31, 2013 and June 30, 2013 calculation dates. The Ratio returns to the pre-amendment maximum of 3.50x for the September 30, 2013 calculation date.

Available borrowings under the Revolving Facility are reduced by any outstanding letters of credit issued by the Corporation under the Revolving Facility. At September 30, 2012, the Corporation had $2,507,000 of outstanding letters of credit issued under the Revolving Facility.

5.	Long-Term Debt (continued)

Accumulated other comprehensive loss includes the unamortized value of terminated forward starting interest rate swap agreements. For the three and nine months ended September 30, 2012, the Corporation recognized $260,000 and $768,000, respectively, as additional interest expense. For the three and nine months ended September 30, 2011, the Corporation recognized $242,000 and $715,000, respectively, as additional interest expense. The ongoing amortization of the terminated value of the forward starting interest rate swap agreements will increase annual interest expense by approximately $1,000,000 until the maturity of the 6.6% Senior Notes in 2018.

6.	Financial Instruments

The Corporation’s financial instruments include temporary cash investments, accounts receivable, notes receivable, bank overdraft, publicly-registered long-term notes, debentures and other long-term debt.

Temporary cash investments are placed primarily in money market funds, money market demand deposit accounts and Eurodollar time deposits with the following financial institutions: Bank of America, N.A., Branch Banking and Trust Company, JPMorgan Chase Bank, N.A., Regions Bank, Fifth Third Bank, and Wells Fargo Bank, N.A. The Corporation’s cash equivalents have maturities of less than three months. Due to the short maturity of these investments, they are carried on the consolidated balance sheets at cost, which approximates fair value.

Customer receivables are due from a large number of customers, primarily in the construction industry, and are dispersed across wide geographic and economic regions. However, customer receivables are more heavily concentrated in certain states (namely, Texas, North Carolina, Iowa, Colorado and Georgia). The estimated fair values of customer receivables approximate their carrying amounts.

Notes receivable are primarily related to divestitures and are not publicly traded. However, using current market interest rates, but excluding adjustments for credit worthiness, if any, management estimates that the fair value of notes receivable approximates the carrying amount.

The bank overdraft represents the float of outstanding checks. The estimated fair value of the bank overdraft approximates its carrying value.

6.	Financial Instruments (continued)

The carrying values and fair values of the Corporation’s long-term debt were $1,098,788,000 and $1,156,820,000, respectively, at September 30, 2012; $1,060,084,000 and $1,087,726,000, respectively, at December 31, 2011; and $1,045,485,000 and $1,072,235,000, respectively, at September 30, 2011. The estimated fair value of the Corporation’s publicly-registered long-term notes was estimated based on level 1 of the fair value hierarchy, quoted market prices. The estimated fair value of other borrowings, which primarily represent variable-rate debt, approximates its carrying amount.

7.	Income Taxes


	Nine Months Ended September 30,
	2012			2011
Estimated effective income tax rate:
Continuing operations		15.9	%		23.6	%

Discontinued operations		34.6	%		40.6	%

Consolidated overall		15.8	%		22.8	%

The Corporation’s effective income tax rate reflects the effect of federal and state income taxes and the impact of differences in book and tax accounting arising from the net permanent benefits associated with the statutory depletion deduction for mineral reserves, the impact of foreign losses for which no tax benefit was realized and the domestic production deduction. The effective income tax rates for discontinued operations reflect the tax effects of individual operations’ transactions and are not indicative of the Corporation’s overall effective income tax rate.

The consolidated overall estimated effective income tax rate for the nine months ended September 30, 2012 included the following discrete events: a refund of federal tax and interest of $1,626,000 related to the 2006 tax year and the estimated effects of an agreement between the taxing authorities of the United States and Canada regarding the transfer price of products for intercompany shipments during the years 2007 to 2011. The effects of the agreement allow the Corporation to utilize certain net operating loss and tax credit carryforwards for which a valuation allowance was previously established. Accordingly, the Corporation reversed a $3,644,000 valuation allowance during the quarter ended September 30, 2012. These discrete events drove a decrease in the consolidated overall estimated effective income tax rate for the nine months ended September 30, 2012. The consolidated overall estimated effective income tax rate for the nine months ended September 30, 2012 would have been 22.7% without these discrete events; a rate more reflective of the expected annual tax rate of 23%.

7.	Income Taxes (continued)

The consolidated overall estimated effective income tax rate for the nine months ended September 30, 2011 included the following discrete events: the favorable effective settlement of the Internal Revenue Service audit for the 2008 tax year; resolution of a federal tax and interest overpayment of $1,730,000 related to the 2006 tax year and an agreed-upon refund of $1,060,000 for the double taxation of the Corporation’s wholly-owned Canadian subsidiary for the 2001 and 2002 tax years.

On December 23, 2011, the U.S. Treasury Department issued comprehensive temporary and proposed regulations addressing the treatment of expenditures related to tangible property for tax purposes. On March 7, 2012, the Internal Revenue Service (“IRS”) issued two revenue procedures containing administrative guidance related to the adoption of the new rules. Although the regulations are generally effective for tax years beginning January 1, 2012, the IRS has granted taxpayers administrative relief and audit protection for a two-year period as long as the taxpayer adopts the regulations retroactively within two years of the effective date. Management has begun to evaluate the changes necessary to comply with the regulations and the related administrative procedures and is not currently aware of any adjustments that would be material to the Corporation’s consolidated financial position and results of operations. As part of its compliance with these regulations, the Corporation reversed its unrecognized tax benefits related to repairs and maintenance as of March 31, 2012.

The Corporation’s unrecognized tax benefits, excluding interest, correlative effects and indirect benefits, are as follows:


	Nine Months Ended September 30, 2012
	(Dollars in Thousands)
Unrecognized tax benefits at beginning of period	$	9,288
Gross increases – tax positions in prior years		19,527
Gross decreases – tax positions in prior years		(13,876	)
Gross increases – tax positions in current year		1,409
Settlements with taxing authorities		(555	)

Unrecognized tax benefits at end of period	$	15,793

For the nine months ended September 30, 2012, gross increases in tax positions in prior years included the estimated effect of the agreement with the taxing authority of Canada that increased the sales price charged for intercompany shipments during the years 2007 through 2011. Upon final settlement, the Corporation will be allowed a corresponding refund of tax in the United States for the years 2007 through 2011 which is not included in the unrecognized tax benefits at September 30, 2012. Accordingly, the Corporation anticipates that it is reasonably possible that unrecognized tax benefits may significantly change up to $9,007,000, excluding indirect benefits, during the twelve months ending September 30, 2013.

7.	Income Taxes (continued)

At September 30, 2012, unrecognized tax benefits of $6,546,000, net of federal tax benefits and related to interest accruals and permanent income tax differences, would have favorably affected the Corporation’s effective income tax rate if recognized.

8.	Pension and Postretirement Benefits

9.	Commitments and Contingencies

Legal and Administrative Proceedings

The Corporation is engaged in certain legal and administrative proceedings incidental to its normal business activities. In the opinion of management and counsel, based upon currently-available facts, it is remote that the ultimate outcome of any litigation and other proceedings, including those pertaining to environmental matters, relating to the Corporation and its subsidiaries, will have a material adverse effect on the overall results of the Corporation’s operations, its cash flows or its financial position.

Environmental and Governmental Regulations

In 2010, the United States Environmental Protection Agency (“USEPA”) included the lime industry as a national enforcement priority under the federal Clean Air Act (“CAA”). As part of the industry wide effort, the USEPA issued Notices of Violation/Findings of Violation (“NOVs”) to the Corporation in 2010 and 2011 regarding the Corporation’s compliance with the CAA New Source Review (“NSR”) program at its Specialty Products dolomitic lime manufacturing plant in Woodville, Ohio. The Corporation has been providing information to the USEPA in response to these NOVs and has had several meetings with the USEPA. The Corporation believes it is in substantial compliance with the NSR program. Because the enforcement proceeding is in its initial stage, at this time the Corporation cannot reasonably estimate what likely penalties or required upgrades to equipment might ultimately be required. The Corporation believes that any costs related to any required upgrades will be spread over time and will not have a material adverse effect on the Corporation’s operations or its financial condition, but can give no assurance that the ultimate resolution of this matter will not have a material adverse effect on the financial condition or results of operations of the Specialty Products segment of the business.

Guarantee of Affiliate

The Corporation has an unconditional guaranty of payment agreement with Fifth Third Bank (“Fifth Third”) to guarantee the repayment of amounts borrowed by an affiliate under a $24,000,000 revolving line of credit provided by Fifth Third that expires in July 2013 and a guaranty agreement with Bank of America, N.A., to guarantee a $6,200,000 amortizing loan due April 2016. The affiliate has agreed to reimburse and indemnify the Corporation for any payments and expenses the Corporation may incur from these agreements. The Corporation holds a subordinate lien of the affiliate’s assets as collateral for potential payments under the agreements.

	$	4,883		$	24,979

The change in accrued income taxes for the nine months ended September 30, 2012 relates to a decrease in current estimated taxable income and the difference in net tax payments for the period. The change in other current and noncurrent assets for the nine months ended September 30, 2012 relates to an increase in costs in excess of billings for the Corporation’s road paving business. The road paving business typically has a longer cash collection cycle compared with the Aggregates business’ other product lines.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

OVERVIEW Martin Marietta Materials, Inc. (the “Corporation”), conducts its operations through four reportable business segments: Mideast Group, Southeast Group, West Group (collectively, the “Aggregates business”) and Specialty Products. The Corporation’s annual net sales and earnings are predominately derived from its Aggregates business, which processes and sells granite, limestone, and other aggregates products, including asphalt, ready mixed concrete and road paving materials, from a network of 307 quarries, distribution facilities and plants to customers in 31 states, Canada, the Bahamas and the Caribbean Islands. The Aggregates business’ products are used primarily by commercial customers principally in domestic construction of highways and other infrastructure projects and for nonresidential and residential building development. Aggregates products are also used in the railroad, environmental, utility and agricultural industries. The Specialty Products segment produces magnesia-based chemicals products used in industrial, agricultural and environmental applications and dolomitic lime sold primarily to customers in the steel industry.

CRITICAL ACCOUNTING POLICIES The Corporation outlined its critical accounting policies in its Annual Report on Form 10-K for the year ended December 31, 2011, filed with the Securities and Exchange Commission (“SEC”) on February 29, 2012. There were no changes to the Corporation’s critical accounting policies during the nine months ended September 30, 2012.

RESULTS OF OPERATIONS

Except as indicated, the following comparative analysis in the Results of Operations section of this Management’s Discussion and Analysis of Financial Condition and Results of Operations reflects results from continuing operations and is based on net sales and cost of sales. The Corporation’s heritage aggregates product line excludes volume and pricing data for acquisitions that have not been included in prior-year operations for the comparable period and divestitures.

Gross margin as a percentage of net sales and operating margin as a percentage of net sales represent non-GAAP measures. The Corporation presents these ratios calculated based on net sales, as it is consistent with the basis by which management reviews the Corporation’s operating results. Further, management believes it is consistent with the basis by which investors analyze the Corporation’s operating results given that freight and delivery revenues and costs represent pass-throughs and have no profit mark-up. Gross margin and operating margin calculated as percentages of total revenues represent the most directly comparable financial measures calculated in accordance with generally accepted accounting principles (GAAP). The following tables present the calculations of gross margin and operating margin for the three and nine months ended September 30, 2012 and 2011 in accordance with GAAP and reconciliations of the ratios as percentages of total revenues to percentages of net sales (dollars in thousands):

The Corporation’s strong third-quarter results reflect both revenue and profit growth that demonstrate the underlying strength of its legacy operations as well as the contribution from its recent acquisitions in the Denver, Colorado market. In terms of the Corporation’s overall performance, the heritage Aggregates business benefitted from both continued strong pricing trends and increased productivity, and the Specialty Products business generated record earnings from operations. The Corporation’s bottom line continued to reflect the diligent manner in which it controls costs. As a result, earnings per diluted share of $1.36, a 27% increase over the prior-year quarter, is especially noteworthy given that the Corporation’s team achieved this in an uncertain economic climate that has been marked by a reluctance on governmental bodies and private industry to commit to long-range capital projects.

The Corporation sees several positive trends in construction activity. First, the Aggregates business continues to benefit from recovery and growth in the residential sector end-use market, which reported a 14% increase in heritage aggregates product line shipments over the prior-year quarter. Second, with the passage of the Moving Ahead for Progress in the 21^st Century Act, or MAP-21, a twenty-seven-month Federal surface transportation bill intended to expedite project approvals and limit spending for programs unrelated to core transportation needs, the level of federal highway funds obligated is increasing. Consequently, many of the Aggregates business’ key states are taking steps to utilize various funding alternatives to support important infrastructure projects. Finally, it seems a backlog of construction work is awaiting, what management believes to be, a general restoration of confidence in the current economic and political environment. The Corporation anticipates these positive trends will continue and provide the prospect for increasing volume momentum as it moves forward into 2013.

Consolidated net sales increased over 20%, with the recently acquired Denver, Colorado area businesses contributing $92 million in the quarter. These operations once again exceeded expectations, reflecting positive construction trends in that market where the rate of growth in highway contract awards ranks among the highest in the country, and, importantly, construction-related employment is well above the national average. Nonresidential construction activity also continues to improve in the market with commercial real estate realizing increased lease rates and decreasing vacancies. Year-to-date housing permits in Colorado increased more than 60%, outpacing the national average, while single-family home sales have increased significantly over the prior-year period.

Heritage aggregates product line pricing increased 4.1% in the quarter over the prior-year period. Pricing growth was led by the Southeast Group, with an overall increase of 5.1% over the prior-year quarter, driven by improvement in all of its markets along with favorable product mix. The West Group reported a heritage aggregates product line price increase of 4.8%, with shipments to the energy sector being a significant driver of this improvement. The Mideast Group had a 3.5% increase in its heritage aggregates product line average selling price, led by growth in the North Carolina, Virginia and West Virginia markets.

Volume trends noted in June continued throughout the third quarter, resulting in a 3.8% decline in heritage aggregates product line shipments versus the comparable prior-year period. Shipments to the infrastructure end-use market, which comprised more than half of heritage aggregates product line volumes, declined 6% compared with the prior-year quarter. Much of the volume decline is attributable to the fact that for nearly three years federal highway spending operated under a series of short-term, continuing resolutions. This extended circumstance made it difficult, and at times impossible, for state departments of transportation to obligate traditional long-term expenditures. This created a chilling effect on various states’ ability to advertise and award significant new highway construction activity.

On July 6, 2012, the President signed into law MAP-21, which maintains highway expenditures at current levels, $40 billion per year, with modest increases to reflect projected inflation and reform provisions. The bill’s passage nine months into the Federal fiscal year ended September 30, 2012 meant that a disproportionately large percentage of federal highway funds were obligated during the last two months of the fiscal year. This delayed timing affected highway construction activity during the quarter and will likely result in many of these projects starting in 2013. However, certain states, namely Texas, Iowa and Florida, have initiated state-level programs that demonstrate the importance of infrastructure investment. In fact, the Texas department of transportation anticipates its spending during fiscal year 2013, which began September 1, to be more than double the amount spent in fiscal year 2012. Additionally, Texas and North Carolina were two of the first states to apply for funding assistance under the Transportation Infrastructure Finance and Innovation Act (TIFIA). Texas submitted requests for TIFIA projects with a cumulative investment of more than $6 billion while North Carolina’s proposed projects total more than $1 billion. TIFIA provides $1.75 billion of federal credit assistance over the next two years for nationally or regionally significant surface transportation projects. Each dollar of federal funds can provide up to $10 in TIFIA credit assistance and leverage up to $30 in transportation infrastructure investment. TIFIA and other state-sponsored programs coupled with MAP-21 should provide an impetus for increased infrastructure spending into 2013 and beyond.

The nonresidential market is the second largest aggregates end use. During the third quarter, this market continued to benefit, as it has for the past couple of years, from a significant level of aggregates product line shipments to the energy sector and other heavy industrial uses. Nonetheless, the nonresidential market also saw more traditional non-energy-related projects delayed during the third quarter. In general, many developers were hesitant to begin new projects due to an inability to accurately estimate their investment returns, including the cost of capital and changes in tax policy, in light of uncertainty surrounding the United States’ fiscal position. As a result, overall heritage shipments to this end-use market were relatively flat compared with the prior year. The residential end-use market growth reflects an approximate 25% increase in year-to-date housing starts over the prior-year period and, as previously mentioned, heritage aggregates shipments increased 14% in the quarter. Finally, the ChemRock/Rail end-use market experienced a 14% decline in heritage shipments compared with the prior-year quarter. The reduction was principally due to the comparison with an unusually strong third quarter for ballast shipments in 2011, as well as a decline in coal traffic on the railroads.

As previously indicated, economic growth was inconsistent across the Corporation’s markets. Aggregates shipment levels varied by geographic area, with notable strength in Texas, West Virginia and Charlotte, North Carolina. This relative robustness was offset by weakness in Ohio, where construction activity on major projects declined, and the West Group, which experienced reduced rail ballast shipments. This weakness led to declines of 2.6% and 2.3% in heritage aggregates product line shipments in the Mideast and West Groups, respectively. The Southeast Group reported a 10.7% decline in heritage aggregates shipments, as economic growth in this region continues to lag national trends, principally due to weak job growth and continued high foreclosure rates.

The following tables present volume and pricing data and shipments data for the aggregates product line. Heritage aggregates operations exclude volume and pricing data for acquisitions that were not included in prior-year operations for the comparable period and divestitures.

The Aggregates business is significantly affected by erratic weather patterns, seasonal changes and other weather-related conditions. Aggregates production and shipment levels coincide with general construction activity levels, most of which occurs in the spring, summer and fall. Thus, production and shipment levels vary by quarter. Operations concentrated in the northern and midwestern United States generally experience more severe winter weather conditions than operations in the Southeast and Southwest. Operations in the Denver, Colorado area increase the Corporation’s exposure to winter weather and the risk of losses in the first and fourth quarters. Excessive rainfall, and conversely excessive drought, can also jeopardize shipments, production and profitability. Because of the potentially significant impact of weather on the Corporation’s operations, third-quarter results are not indicative of expected performance for other interim periods or the full year.

Specialty Products continued its strong performance in both the chemicals and dolomitic lime product lines. For the quarter, net sales were $49.4 million and record third-quarter earnings from operations were $17.0 million, or 34.4% of net sales, an improvement of 350 basis points. The new dolomitic lime kiln recently completed at the Woodville, Ohio, facility will begin generating sales in the fourth quarter. The new kiln is expected to provide incremental annual net sales ranging from $22 million to $25 million with margins comparable to existing operations.

Consolidated gross margin (excluding freight and delivery revenues) for the quarter was 22.9%, a 220-basis-point decline compared with the prior-year quarter. The decline was primarily attributable to the increased impact of newly acquired Colorado businesses, which is more vertically integrated (i.e., with more ready mixed concrete, hot mixed asphalt and related paving operations) than the Corporation’s traditional heritage business. In fact, excluding the effect of these recently acquired businesses, consolidated gross margin (excluding freight and delivery revenues) would have been 25.6%, an improvement of 50 basis points over the prior-year quarter. Notably, the Mideast Group benefitted during the quarter from pricing growth to increase net sales, and coupled this sales growth with reduced personnel costs to increase its gross margin (excluding freight and delivery revenues) by 180 basis points to 33.7%.

Increase in consolidated gross profit		11,691

Consolidated gross profit, quarter ended September 30, 2012	$	123,584

Direct production costs for the heritage aggregates product line fell $6.3 million, or 2.7%, as production levels were reduced to better match shipment activity. Operations personnel prudently managed costs and limited the increase in cost per ton to 1.0%, despite this decline.

Nonproduction costs for the heritage aggregates product line include freight expenses to transport materials from a producing quarry to a distribution yard and resale material. During the quarter, internal rail freight costs increased due to additional volumes being shipped to materials yards, particularly in the West Group.

Consolidated SG&A expenses were 6.0% of net sales, an improvement of 140 basis points compared with the prior-year quarter. On an absolute basis, SG&A decreased $0.7 million despite absorbing overhead incurred at the Corporation’s Denver operations as well as costs related to an information systems upgrade expected to be completed by the fall of 2013. Included in third-quarter 2011 SG&A expenses were $2.8 million of nonrecurring early retirement benefits.

Among other items, other operating income and expenses, net, includes gains and losses on the sale of assets; gains and losses related to customer accounts receivable; rental, royalty and services income; and the accretion and depreciation expenses related to asset retirement obligations. For the third quarter, consolidated other operating income and expenses, net, was an expense of $0.4 million in 2012 compared with income of $1.6 million in 2011, primarily as a result of higher gains on the sale of assets in during the third quarter of 2011.

For the nine months, net sales for the Aggregates business were $1.229 billion in 2012 versus $996.1 million in 2011, primarily due to the acquisition of operations in Denver, Colorado, and growth in the Corporation’s nonresidential and residential end-use markets. Shipments to the heritage nonresidential end-use market increased 9% as energy-sector activity continues to grow. The residential end-use market continues to recover from the depressed levels of the past few years, reflecting the increase in national year-to-date housing permits. For the nine-month period ended September 30, 2012, heritage aggregates volume increased 2.2%, while pricing increased 3.0%.

Increased direct production costs and nonproduction costs for the heritage aggregates product line, coupled with the Corporation’s increased exposure to vertically-integrated businesses, reduced the Corporation’s gross margin (excluding freight and delivery revenues) for the nine months ended September 30 by 220 basis points to 18.1% in 2012. The following presents a rollforward of the Corporation’s gross profit (dollars in thousands):

The heritage aggregates product line continues to absorb the significant financial impact of higher energy expenses, particularly diesel fuel, which represents the single largest component of its energy costs. For the first nine months, the Aggregates business paid an average of $3.12 per gallon in 2012 compared with $2.96 in the prior-year period.

For the nine months ended September 30, 2012, other production costs for the heritage aggregates product line increased $8.9 million over the prior-year period due to higher costs for labor, repairs, supplies and royalty expenses. Direct production costs per ton increased 1.2% over the comparable prior-year period.

Nonproduction costs for the heritage aggregates product line increased $23.1 million compared with the prior-year period. Internal freight costs for the heritage aggregates operations increased $12.9 million compared with the prior-year period. While higher diesel fuel costs experienced during the first nine months contributed to the increase in internal freight costs, the rail component increased due to increased shipments to materials yards, particularly in the West Group. Additionally, resale material costs increased significantly during the first half of 2012 as the Corporation was unable to produce enough material to support well drilling for the oil and gas industry, particularly in the Mideast Group, and purchased the products for its customers.

Consolidated SG&A expenses were 7.3% of net sales, an 80-basis-point improvement compared with the prior-year period. On an absolute basis, SG&A expenses increased $8.0 million, as expected, primarily related to the acquired operations in the Denver, Colorado market and costs related to an information systems upgrade expected to be completed by the fall of 2013.

During the nine months ended September 30, 2012, the Corporation incurred $35.1 million of business development costs.

For the nine months ended September 30, consolidated other operating income and expenses, net, was income of $1.1 million in 2012 compared with income of $4.0 million in 2011, primarily as a result of higher gains on the sale of assets in 2011.

Interest expense was $40.0 million for the nine months ended September 30, 2012 compared with $45.3 million for the prior-year period. The decrease in 2012 was due to a higher mix of variable-rate debt which currently bears a lower interest rate than the Corporation’s fixed-rate debt.

In addition to other offsetting amounts, other nonoperating income and expenses, net, are comprised generally of interest income and net equity earnings from nonconsolidated investments. Consolidated other nonoperating income and expenses, net, for the nine months ended September 30, was income of $1.3 million in 2012 compared with an expense of $2.2 million in 2011, primarily due to the gain resulting from a bond repurchased at a discount in 2012.

Since 2007, the Corporation has been pursuing a bilateral advanced pricing agreement between the Internal Revenue Service and the Canada Revenue Agency for the transfer price of products for intercompany shipments. In September 2012, the Corporation was informally notified that the two parties reached an agreement on an adjustment to the amount charged for the covered tax years of 2007 through 2011, but have not yet agreed on a method to be used to calculate the transfer price going forward. The financial statements reflect an estimate of the impact of agreement, including the reversal of a valuation allowance on net operating loss and tax credit carryforwards that are expected to be utilized to offset the increase in the Corporation’s wholly-owned Canadian subsidiary’s taxable income for the tax years 2007 through 2011. Discrete events drove a decrease in the consolidated overall estimated effective income tax rate for the nine months ended September 30, 2012. The consolidated overall estimated effective income tax rate for the nine months ended September 30, 2012 would have been 22.7% without these discrete events; a rate more reflective of the expected annual tax rate of 23%.

LIQUIDITY AND CAPITAL RESOURCES

Cash provided by operating activities for the nine months ended September 30, 2012 was $122.0 million. Excluding the impact of business development expenses, cash provided by operating activities for the nine months ended September 30, 2012 was $160.0 million compared with $179.9 million for the same period in 2011. Operating cash flow is primarily derived from consolidated net earnings or loss, before deducting depreciation, depletion and amortization, and offset by working capital requirements. Depreciation, depletion and amortization were as follows:


	Nine Months Ended September 30,
	2012		2011
	(Dollars in Thousands)
Depreciation	$	125,534	$	124,676
Depletion		3,446		2,592
Amortization		4,005		2,405

	$	132,985	$	129,673

Additionally, the Corporation’s December 2011 asset exchange changed the timing of cash flows throughout the year, with increased cash flows generated by the Denver operations expected to be realized in the second half of the year. Cash used for operating activities by the Denver operations was approximately $52 million during the first nine months of 2012. Days sales outstanding was 44.7 days, down from 45.2 days in 2011.

The seasonal nature of the construction aggregates business impacts quarterly operating cash flow when compared with the full year. Full year 2011 net cash provided by operating activities was $259.1 million compared with $179.9 million for the first nine months of 2011.

During the nine months ended September 30, 2012, the Corporation invested $105.9 million of capital into its business, including $32 million related to the new kiln at its Specialty Products location in Woodville, Ohio. The new kiln, which became functional on November 1, 2012, will begin to generate sales in the fourth quarter. On an annual basis, the new kiln is expected to provide net sales ranging from $22 million to $25 million. Full-year capital spending, exclusive of acquisitions, if any, is expected to be approximately $155 million in 2012. Comparable full-year capital expenditures were $155.4 million in 2011.

On January 23, 2012, the Corporation repurchased $20.0 million par value of its outstanding 6.25% Senior Notes due 2037 at 90.75. This repurchase was financed with borrowings of $18.2 million under the Corporation’s Revolving Facility.

The Corporation can repurchase its common stock through open-market purchases pursuant to authority granted by its Board of Directors. The Corporation did not repurchase any shares of common stock during the nine months ended September 30, 2012 and 2011. Management currently has no intent to repurchase any shares of the Corporation’s common stock. At September 30, 2012, 5,042,000 shares of common stock were remaining under the Corporation’s repurchase authorization.

The Credit Agreement (which consists of the Term Loan Facility and a $350 million Revolving Facility) and the AR Credit Facility require the Corporation’s ratio of consolidated debt to consolidated earnings before interest, taxes, depreciation, depletion and amortization (EBITDA), as defined, for the trailing twelve month period (the “Ratio”) to not exceed 3.50x as of the end of any fiscal quarter, provided that the Corporation may exclude from the Ratio debt incurred in connection with certain acquisitions for a period of 180 days so long as the Corporation, as a consequence of such specified acquisition, does not have its ratings on long-term unsecured debt fall below BBB by Standard & Poor’s or Baa2 by Moody’s and the Ratio calculated without such exclusion does not exceed 3.75x. Additionally, if there are no amounts outstanding under both the Revolving Facility and the AR Credit Facility, consolidated debt, including debt guaranteed by the Corporation, will be reduced for purposes of the covenant calculation by the Corporation’s unrestricted cash and cash equivalents in excess of $50 million, such reduction not to exceed $200 million (hereinafter, “net debt”).

In order to increase the cushion between the Ratio and the covenant limit, on October 17, 2012, the Corporation amended the Ratio to maintain the maximum Ratio of 3.75x for the December 31, 2012, March 31, 2013 and June 30, 2013 calculation dates. The calculation returns to the pre-amended maximum of 3.50x for the September 30, 2013 calculation date. Management anticipates the Ratio will stay below the unadjusted 3.50x level for the periods when the amendment increases the maximum Ratio to 3.75x.

The Ratio is calculated as debt, including debt guaranteed by the Corporation, divided by consolidated EBITDA, as defined, for the trailing twelve months. Consolidated EBITDA is generally defined as earnings before interest expense, income tax expense, and depreciation, depletion and amortization expense for continuing operations. Additionally, stock-based compensation expense is added back and interest income is deducted in the calculation of consolidated EBITDA. Certain other nonrecurring noncash items, if they occur, can affect the calculation of consolidated EBITDA.

Consolidated debt to consolidated EBITDA, as defined, at September 30, 2012 for the trailing twelve months EBITDA		3.58 X

In the event of a default on the Ratio, the lenders can terminate the Credit Agreement and AR Credit Facility and declare any outstanding balances as immediately due.

Cash on hand, along with the Corporation’s projected internal cash flows and availability of financing resources, including its access to debt and equity capital markets, are expected to continue to be sufficient to provide the capital resources necessary to support anticipated operating needs, cover debt service requirements, meet capital expenditures and discretionary investment needs, fund certain acquisition opportunities that may arise and allow for payment of dividends for the foreseeable future. At September 30, 2012, the Corporation had $250 million of unused borrowing capacity under its Revolving Facility, subject to complying with the related leverage covenant, and no available borrowings under its AR Credit Facility. The Credit Agreement expires on March 31, 2015 and the AR Credit Facility, as amended, terminates on April 20, 2013.

The Corporation may be required to obtain financing to fund certain strategic acquisitions, if any such opportunities arise, or to refinance outstanding debt. A strategic acquisition of size for cash would likely require an appropriate balance of newly-issued equity with debt in order to maintain a composite investment-grade credit rating. Furthermore, the Corporation is exposed to the credit markets, through the interest cost related to its variable-rate debt, which includes borrowings under its Revolving Facility, Term Loan Facility and AR Credit Facility, and the interest cost related to its commercial paper program, to the extent that it is available to the Corporation. The Corporation is currently rated by three credit rating agencies, and while two of those agencies’ credit ratings are investment-grade level, on July 12, 2012, the third agency reduced its rating to one level below investment grade. The Corporation’s composite credit rating remains at investment-grade level, which facilitates obtaining financing at lower rates than noninvestment-grade ratings. While management believes its composite credit ratings will remain at an investment-grade level, no assurance can be given that these ratings will remain at current levels.

TRENDS AND RISKS The Corporation outlined the risks associated with its business in its Annual Report on Form 10-K for the year ended December 31, 2011, filed with the Securities and Exchange Commission on February 29, 2012. Management continues to evaluate its exposure to all operating risks on an ongoing basis.

OUTLOOK

As discussed, management is encouraged by various positive trends in the Corporation’s markets. For full year 2012, management anticipates high-single-digit volume growth in the nonresidential end-use market, driven primarily by increased energy shipments; some energy-sector activity will continue to be affected by natural gas prices, the timing of lease commitments for oil and natural gas companies, geographic transitions and weather conditions. Management expects the rate of improvement in the Corporation’s residential end-use market to accelerate over the rate of improvement in 2011. The infrastructure end-use market volume is expected to be down slightly and ChemRock/Rail shipments are expected to be down in the high-single digits.

As such, management anticipates that heritage aggregates product line shipments for the full year will increase from 1% to 2%, and pricing will increase 2% to 4%. A variety of factors beyond the Corporation’s direct control may continue to exert pressure on volumes and forecasted pricing increase is not expected to be uniform across the company. Heritage aggregates product line direct production costs per ton are expected to be up slightly compared with 2011.

Earnings for the Specialty Products segment should be approximately $68 million to $70 million. Steel utilization and natural gas prices are two key factors for this segment.

SG&A expenses, excluding the incremental expense related to the Denver operations and costs related to the information systems upgrade, are expected to decline slightly. Management expects improvement in SG&A expenses related to the Denver operations as the Corporation fully completes their integration. Interest expense should decrease approximately $5 million compared with 2011. The Corporation’s effective tax rate is expected to approximate 23%, excluding discrete events. Capital expenditures are forecast at $155 million.

Management has started framing a preliminary 2013 outlook for the Corporation’s end-use markets. Management currently expects shipments to the infrastructure end-use market to increase in the mid-single digits, driven by the impact of MAP-21, TIFIA and state-sponsored programs. Management anticipates the nonresidential end-use market to increase in the high-single digits. Management believes the recent positive trend in housing starts will continue and the residential end-use market will experience double-digit volume growth. Finally, management expects the ChemRock/Rail end-use market to be flat compared with 2012. Management will provide further guidance on the Corporation’s 2013 outlook in its year-end earnings release.

The full-year 2012 outlook and preliminary 2013 outlook for the Corporation’s end-use markets include management’s assessment of the likelihood of certain risk factors that will affect performance. The most significant risk to 2012 performance will be the United States economy and its impact on construction activity. The resolution of the fiscal cliff and whether tax increases and spending cuts take effect may have a significant impact on the economy and, consequently, construction activity. Other risks related to the Corporation’s future performance include, but are not limited to, both price and volume and include a recurrence of widespread decline in aggregates volume negatively affecting aggregates price; the termination, capping and/or reduction of the federal and/or state gasoline tax(es) or other revenue related to infrastructure construction; a significant change in the funding patterns for traditional federal, state and/or local infrastructure projects; a reduction in defense spending, and the subsequent impact on construction activity on or near military bases, particularly if sequestration of budget programs occurs; a decline in nonresidential construction, a decline in energy-related drilling activity resulting from certain regulatory or economic factors, a slowdown in the residential construction recovery, or some combination thereof; and a continued reduction in ChemRock/Rail shipments resulting from declining coal traffic on the railroads. Further, increased highway construction funding pressures resulting from either federal or state issues can affect profitability. Currently, nearly all states have general fund budget issues driven by lower tax revenues. If these negatively affect transportation budgets more than in the past, construction spending could be reduced. North Carolina and Texas, states disproportionately affecting the Corporation’s revenue and profitability, are among the states experiencing these fiscal pressures, although recent statistics indicate that transportation budgets and tax revenues are increasing.

The Corporation’s principal business serves customers in aggregates-related construction markets. This concentration could increase the risk of potential losses on customer receivables; however, payment bonds normally posted on public projects, together with lien rights on private projects, help to mitigate the risk of uncollectible receivables. The level of aggregates demand in the Corporation’s end-use markets, production levels and the management of production costs will affect the operating leverage of the Aggregates business and, therefore, profitability. Production costs in the Aggregates business are also sensitive to energy prices, both directly and indirectly. Diesel fuel and other consumables change production costs directly through consumption or indirectly by increased energy-related input costs, such as, steel, explosives, tires and conveyor belts. Fluctuating diesel fuel pricing also affects transportation costs, primarily through fuel surcharges in the Corporation’s long-haul distribution network. The Specialty Products business is sensitive to changes in domestic steel capacity utilization and the absolute price and fluctuations in the cost of natural gas. However, due to recent technology developments allowing the harvesting of abundant natural gas supplies in the U.S., natural gas prices have stabilized.

Transportation in the Corporation’s long-haul network, particularly rail cars and locomotive power to move trains, affects its ability to efficiently transport material into certain markets, most notably Texas, Florida and the Gulf Coast. The availability of trucks to transport the Corporation’s product, particularly in markets experiencing increased demand due to energy sector activity, is also a risk. The Aggregates business is also subject to weather-related risks that can significantly affect production schedules and profitability. The first and fourth quarters are most adversely affected by winter weather, and the acquisitions of operations in the Denver, Colorado, market increased the Corporation’s exposure to winter weather. Hurricane activity in the Atlantic Ocean and Gulf Coast generally is most active during the third and fourth quarters.

Risks to the full-year outlook include shipment declines as a result of economic events beyond the Corporation’s control. In addition to the impact on nonresidential and residential construction, the Corporation is exposed to risk in its estimated outlook from credit markets and the availability of and interest cost related to its debt.

The Corporation’s future performance is also exposed to risk from tax reform at the federal and state levels.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

The Corporation’s operations are highly dependent upon the interest rate-sensitive construction and steelmaking industries. Consequently, these marketplaces could experience lower levels of economic activity in an environment of rising interest rates or escalating costs.

Management has considered the current economic environment and its potential impact to the Corporation’s business. Demand for aggregates products, particularly in the nonresidential and residential construction markets, could decline if companies and consumers are unable to obtain financing for construction projects or if an economic recession causes delays or cancellations to capital projects. Additionally, declining tax revenues and state budget deficits have negatively affected states’ abilities to finance infrastructure construction projects.

Demand in the residential construction market is affected by interest rates. The Federal Reserve kept the federal funds rate at zero percent during the quarter ended September 30, 2012. The residential construction market accounted for approximately 8% of the Corporation’s heritage aggregates product line shipments in 2011.

Aside from these inherent risks from within its operations, the Corporation’s earnings are affected also by changes in short-term interest rates as a result of any temporary cash investments, including money market funds and Eurodollar time deposit accounts; any outstanding variable-rate borrowing facilities; and defined benefit pension plans. Additionally, the Corporation’s earnings are affected by energy costs. The Corporation has no material counterparty risk.

Variable-Rate Borrowing Facilities. The Corporation has a $600 million Credit Agreement, comprised of a $350 million Revolving Facility and $250 million Term Loan Facility, and a $100 million AR Credit Facility. Borrowings under these facilities bear interest at a variable interest rate. A hypothetical 100-basis-point increase in interest rates on borrowings of $445 million, which is the collective outstanding balance at September 30, 2012, would increase interest expense by $4.5 million on an annual basis.

Pension Expense. The Corporation’s results of operations are affected by its pension expense. Assumptions that affect pension expense include the discount rate and, for the defined benefit pension plans only, the expected long-term rate of return on assets. Therefore, the Corporation has interest rate risk associated with these factors. The impact of hypothetical changes in these assumptions on the Corporation’s annual pension expense is discussed in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2011, filed with the Securities and Exchange Commission on February 29, 2012.

Energy Costs. Energy costs, including diesel fuel, natural gas and liquid asphalt, represent significant production costs for the Corporation. A hypothetical 10% change in the Corporation’s energy prices in 2012 as compared with 2011, assuming constant volumes, would impact annual 2012 pretax earnings by approximately $16.8 million.

Aggregate Risk for Interest Rates and Energy Costs. Pension expense for 2012 is calculated based on assumptions selected at December 31, 2011. Therefore, interest rate risk in 2012 is limited to the potential effect related to the Corporation’s borrowings under variable-rate facilities. The effect of a hypothetical increase in interest rates of 1% on $445 million of variable-rate borrowings outstanding at September 30, 2012 would increase interest expense on an annual basis by $4.5 million. Additionally, a 10% change in energy prices compared with 2011 would impact annual pretax earnings by $16.8 million.

Item 4. Controls and Procedures

As of September 30, 2012, an evaluation was performed under the supervision and with the participation of the Corporation’s management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and the operation of the Corporation’s disclosure controls and procedures. Based on that evaluation, the Corporation’s management, including the Chief Executive Officer and Chief Financial Officer, concluded that the Corporation’s disclosure controls and procedures were effective as of September 30, 2012. As permitted by the Securities and Exchange Commission, the Corporation’s management excluded its newly-acquired Denver operations from its internal control over financial reporting as of September 30, 2012. These Denver operations accounted for approximately 7% of the Company’s consolidated total assets at December 31, 2011. There were no changes in the Corporation’s internal control over financial reporting during the most recently completed fiscal quarter that materially affected, or are reasonably likely to materially affect, the Corporation’s internal control over financial reporting.
