For the Quarter Ended March 31, 2007

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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, 2006, filed with the Securities and Exchange Commission on February 28, 2007. 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 for the interim periods. The results of operations for the three months ended March 31, 2007 are not indicative of the results expected for the full year.

		Retirement Plans and Postretirement Benefits

		On December 31, 2006, the Corporation adopted the recognition and disclosure provisions of Statement of Financial Accounting Standards No. 158, Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans, an Amendment of FAS 87, 88, 106 and 132(R) (“FAS 158”) prospectively. In connection with the adoption, the Corporation increased accumulated other comprehensive loss by $20,418,000, net of tax, at December 31, 2006 for the net unrecognized actuarial losses, unrecognized prior service costs and unrecognized transition obligations remaining from the initial adoption of FAS 87 and FAS 106. During the three months ended March 31, 2007, $449,000, net of tax, of these unrecognized amounts was recognized as a component of net periodic benefit cost pursuant to the Corporation’s historical accounting policy for amortizing such amounts.

		Uncertain Tax Positions

		Effective January 1, 2007, the Corporation adopted Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an Interpretation of FAS 109(“FIN 48”). FIN 48 requires the recognition of a tax benefit when it is “more-likely-than-not,” based on the technical merits, that the position would be sustained upon examination by a taxing authority. The amount to be recognized should be measured as the largest amount of tax benefit that is greater than 50 percent likely of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information.

For the Quarter Ended March 31, 2007

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Continued)

1.		Significant Accounting Policies (continued)

		Uncertain Tax Positions (continued)

		In connection with the adoption of FIN 48, the Corporation increased its reserves for uncertain tax positions and reduced retained earnings at January 1, 2007 by $1,407,000, primarily as a result of providing interest accruals on uncertain temporary tax positions related to temporary or timing differences.

		At January 1, 2007, the total amount of gross unrecognized tax benefits, excluding interest, was $29,248,000. Unrecognized tax benefits of $10,577,000, net of federal tax benefits, related to interest accruals and permanent income tax differences would favorably affect the Corporation’s effective tax rate if recognized. There have been no significant changes to these amounts during the quarter ended March 31, 2007.

		The Corporation anticipates that it is reasonably possible that the total amounts of unrecognized tax benefits may significantly change within the succeeding twelve months as a result of the expiration of the federal statute of limitations for examination of the 2003 tax year and the settlement of the Internal Revenue Service audits for the 2004 and 2005 tax years. The Corporation estimates that these events could result in a reasonably possible change in unrecognized tax benefits ranging from $8,278,000 to $27,772,000.

		The Corporation records interest accrued in relation to unrecognized tax benefits as income tax expense and penalties, if incurred, are recorded as operating expenses in the consolidated statement of earnings. Accrued interest of $4,984,000 was recorded as a current FIN 48 liability in the Corporation’s consolidated balance sheet at March 31, 2007.

		The Corporation’s open tax years that are subject to examination are 2003 through 2006. The Internal Revenue Service is currently auditing the Corporation’s consolidated federal income tax returns for the years ended December 31, 2005 and 2004.

2.		Divestitures and Discontinued Operations

		In 2007, the Corporation disposed of or permanently shut down certain underperforming operations in the following markets:


		Reportable Segment		Markets
		Mideast Group		West Virginia
		West Group		Kansas and New Mexico

These divestitures 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 on the consolidated statements of earnings.

The carrying values of the Notes due in 2008 included $3,907,000, $4,469,000 and $6,110,000 at March 31, 2007, December 31, 2006 and March 31, 2006, respectively, for the unamortized value of terminated interest rate swaps.

The Corporation entered into two forward starting interest rate swap agreements in September 2006 related to $150,000,000 of the Corporation’s anticipated refinancing of its $200,000,000 5.875% Notes due in 2008 (the “Swap Agreements”). At March 31, 2007, the fair value of the Swap Agreements was a liability of $1,617,000 and was included in other noncurrent liabilities in the Corporation’s consolidated balance sheet. Other comprehensive earnings/loss for the three months ended March 31, 2007 included a gain of $202,000, net of tax, for the change in fair value of the Swap Agreements. At December 31, 2006, the fair value of the Swap Agreements was a liability of $1,951,000.

Borrowings of $248,000,000 were outstanding under the commercial paper program at March 31, 2007. No commercial paper borrowings were outstanding at December 31, 2006 or March 31, 2006.

At March 31, 2007 and December 31, 2006, borrowings of $5,083,000 and $537,000, respectively, were outstanding under a $10,000,000 line of credit. No borrowings were outstanding under the line of credit at March 31, 2006.

As described more fully in Note 10, the Corporation issued $475,000,000 of Senior Notes subsequent to March 31, 2007 and repaid its outstanding commercial paper obligations and other short-term loans.

Income Taxes


	Three Months Ended March 31,
	2007			2006
Estimated effective income tax rate:
Continuing operations		33.8	%		31.7	%

Discontinued operations		32.9	%		32.0	%

Overall		33.8	%		31.7	%

The Corporation’s effective tax rate reflects the effect of state income taxes and the impact of differences in book and tax accounting arising from the net permanent benefits associated with the depletion allowances for mineral reserves, the domestic production deduction, foreign operating earnings and the tax effect of nondeductibility of goodwill related to asset sales. 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 tax rate.

The increase in the Corporation’s effective tax rate for continuing operations for the first quarter 2007 results from the discrete tax impact of stock option exercises during the quarter, deemed dividends on certain foreign source income and the effect of applying FIN 48. The effective income tax rate increased 90 basis points during the first quarter 2007 as a result of the evaluation of the Corporation’s tax positions in accordance with FIN 48.

9.		Business Segments

		In the fourth quarter of 2006, the Corporation reorganized the operations and management of its Aggregates business, which resulted in a change to its reportable segments. Currently, the Corporation conducts its aggregates operations through three reportable business segments: Mideast Group, Southeast Group and West Group. The Corporation also has a Specialty Products segment that includes magnesia chemicals, dolomitic lime and focused activity in structural composites.

		The following tables display selected financial data for the Corporation’s reportable business segments (dollars in thousands). Corporate loss from operations primarily includes depreciation on capitalized interest, expenses for corporate administrative functions, unallocated corporate expenses and other nonrecurring and/or non-operational adjustments. Prior year information has been reclassified to conform to the presentation of the Corporation’s current reportable segments.

10.		Subsequent Events

		Subsequent to March 31, 2007, the Corporation repurchased 283,000 shares of its common stock at an aggregate price of $38,927,000, or $137.55 per share, pursuant to a 10b5-1 plan.

		During April 2007, the Corporation borrowed $100,000,000 of money market notes at a weighted average interest rate of 5.43%. The money market notes matured through May 2, 2007.

		On April 17, 2007, the Corporation entered into an amendment of its $250,000,000 five-year revolving credit agreement, which modified the leverage ratio covenant in the agreement. As modified, the covenant requires the Corporation’s ratio of consolidated debt to consolidated earnings before interest, taxes, depreciation, depletion and amortization (EBITDA), as defined, for the trailing twelve months to not exceed 2.75 to 1.00 as of the end of any fiscal quarter. The covenant has certain exceptions related to qualifying acquisitions, as defined.

		On April 25, 2007, the Corporation issued $250,000,000 of 6.25% Senior Notes due in 2037 and $225,000,000 of Floating Rate Senior Notes due in 2010 (collectively, the “Notes”). The 6.25% Senior Notes may be redeemed in whole or in part prior to their maturity at a “make whole” redemption price. The Floating Rate Senior Notes bear interest at a rate equal to the three-month LIBOR plus 0.15% and may not be redeemed prior to maturity. Upon a change of control repurchase event, the Corporation will be required to make an offer to repurchase all outstanding Notes at a price in cash equal to 101% of the principal amount of the Notes, plus any accrued and unpaid interest to, but not including, the purchase date. The Notes, which are unsecured, were used to repay the Corporation’s outstanding commercial paper obligations ($248,000,000 outstanding at March 31, 2007) and other short-term loans and are anticipated to be used to fund the repayment of its $125,000,000 6.9% Notes due in August 2007.

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 net sales and earnings are predominately derived from its Aggregates business, which processes and sells granite, limestone, and other aggregates products from a network of 310 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 commercial and residential buildings. The Specialty Products segment produces magnesia-based chemicals products used in industrial, agricultural and environmental applications; dolomitic lime sold primarily to customers in the steel industry; and structural composite products.

CRITICAL ACCOUNTING POLICIES The Corporation outlined its critical accounting policies in its Annual Report on Form 10-K for the year ended December 31, 2006, filed with the Securities and Exchange Commission on February 28, 2007.

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.

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 months ended March 31, 2007 and 2006 in accordance with GAAP and reconciliations of the ratios as percentages of total revenues to percentages of net sales (dollars in thousands):

Net sales for the Aggregates business for the 2007 first quarter were $375.9 million, a 1.6% decrease over 2006 first-quarter sales of $382.0 million. Aggregates pricing at heritage locations was up 15.4%, while volume decreased 14.6%. Inclusive of acquisitions and divestitures, aggregates pricing for the quarter increased 15.3% and aggregates product line volume decreased 14.8%. Aggregates pricing was better than expected due to favorable product and geographic mix. Severe winter weather conditions, particularly in the West Group and in the Indiana and Ohio areas, led to weaker than expected volumes and skewed sales volume towards the Southeastern and Carolinas markets, leading to the favorable geographic mix. In addition to the weather effect on volume, aggregates demand from residential construction was down significantly, as expected.

Aggregates quarry-level production costs decreased during the quarter. The primary driver of cost reduction was the control of labor costs during the quarter, particularly in those areas hardest hit by severe winter weather. Total paid man-hours declined nearly 15%, while productivity, as measured by tons per paid man-hour, increased 3.5% as compared with the prior-year quarter.

(3)		Aggregates Business includes all acquisitions from the date of acquisition and divestitures through the date of disposal.

(4)		Divestitures include the tons related to divested operations up to the date of divestiture.

The Aggregates business is significantly affected by 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 United States generally experience more severe winter weather conditions than operations in the Southeast and Southwest. Furthermore, excessive rainfall can also jeopardize shipments, production and profitability. Because of the potentially significant impact of weather on the Corporation’s operations, first quarter results are not indicative of expected performance for the year.

RESULTS OF OPERATIONS
First Quarter Ended March 31, 2007
(Continued)

First-quarter results for the Specialty Products segment, which includes magnesia chemicals, dolomitic lime and focused activity in structural composites, were positive, despite declining sales. Specialty Products’ net sales were $38.5 million for the first quarter 2007 compared with $41.4 million for the prior-year period. Earnings from operations for the quarter were $7.4 million compared with $6.9 million in the year-earlier period. Management has established specific quarterly benchmarks for 2007 to evaluate the viability of the remaining components of the structural composites product line.

Selling, general and administrative expenses as a percentage of net sales for the quarter increased from 8.5% in 2006 to 9.2% in 2007. The growth in the expense ratio results from lower sales revenue coupled with $1.6 million in increased performance-based incentive compensation costs that reward senior management based on the excess of return on invested capital as compared to the weighted average cost of capital.

Among other items, other operating income and expenses, net, includes gains and losses on the sale of assets; gains and losses related to certain accounts receivable; rental, royalty and services income; and the accretion and depreciation expenses related to Statement of Financial Accounting Standards No. 143, Accounting for Asset Retirement Obligations. For the first quarter, consolidated other operating income and expenses, net, was income of $2.5 million in 2007 compared with $3.6 million in 2006. The decrease resulted primarily from a $2.1 million judgment in favor of the Corporation in connection with a land condemnation in 2006 and was partially offset by higher gains on receivables in 2007.

Consolidated interest expense was $11.2 million for the first quarter 2007 as compared with $10.0 million for the prior-year quarter. The increase resulted from $0.6 million of interest on outstanding commercial paper obligations and a lower amount of capitalized interest related to major plant expansion and efficiency projects in 2007 as compared with the prior-year quarter.

In addition to other offsetting amounts, other nonoperating income and expenses, net, are comprised generally of interest income, net equity earnings from nonconsolidated investments and eliminations of minority interests for consolidated non-wholly owned subsidiaries. Consolidated other nonoperating income and expenses, net, for the quarter ended March 31, was income of $2.7 million in 2007 compared with $2.1 million in 2006. For the quarter ended March 31, 2007, the elimination of minority interest for consolidated subsidiaries decreased other nonoperating expense by $0.6 million and was offset by a $0.7 million decrease in interest income.

The Corporation’s effective income tax rate for continuing operations increased to 33.8% for the first quarter 2007 as compared with 31.7% for the prior-year quarter. The increase in the effective tax rate results from the discrete tax impact of stock option exercises during the quarter, deemed dividends on certain foreign source income and the effect of applying Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an Interpretation of FAS 109 (“FIN 48”). FIN 48 requires that management evaluate its tax positions for all open tax years to determine if the position is more-likely-than-not to be sustained upon examination by taxing authorities having full knowledge of all relevant information. The effective income tax rate increased 90 basis points during the quarter as a result of the evaluation of the Corporation’s tax positions in accordance with FIN 48.

LIQUIDITY AND CAPITAL RESOURCES Net cash provided by operating activities during the three months ended March 31, 2007 was $49.1 million compared with $32.5 million in the comparable period of 2006. Operating cash flow is generally from net earnings, before deducting depreciation, depletion and amortization, offset by working capital requirements. Net cash provided by operating activities for the first three months of 2007 as compared with the year-earlier period reflects slightly higher earnings, a higher accrual for income tax obligations and a lower increase in accounts receivable in 2007 resulting from better collection efforts and lower sales, and was partially offset by a higher build up of inventories and increased tax benefits from stock option exercise activity.

Depreciation, depletion and amortization was as follows (amounts in millions):


	Three Months Ended
	March 31,
	2007		2006
Depreciation	$	34.4	$	30.7
Depletion		0.9		0.9
Amortization		0.7		1.1

	$	36.0	$	32.7

The seasonal nature of the construction aggregates business impacts quarterly operating cash flow when compared with the year. Full year 2006 net cash provided by operating activities was $338.2 million, compared with $32.5 million for the first three months of 2006.

First quarter capital expenditures, exclusive of acquisitions, were $49.9 million in 2007 and $74.4 million in 2006. Capital expenditures during the first three months of 2006 included work on several major plant expansion and efficiency projects. Comparable full-year capital expenditures were $266.0 million in 2006. Full-year capital spending is expected to approximate $235.0 million for 2007, including the Hunt Martin joint venture and exclusive of acquisitions, if any. Additionally, in 2007, the Corporation expects to enter into a lease agreement for 50 barges with a total commitment of approximately $24.0 million.

During the first quarter of 2006, the Corporation received repayment of a $12.5 million note receivable related to the divestiture of its Houston asphalt operations. The Corporation continues to have a continuing financial interest in the Houston asphalt market via a supply agreement and therefore continues to include the divested locations in continuing operations.

During 2007, the Corporation continued its common stock repurchase plan through open-market purchases pursuant to authority granted by its Board of Directors. In February 2006, the Board of Directors authorized management to repurchase up to an additional 5.0 million shares of its common stock. For the quarter ended March 31, 2007, the Corporation repurchased 2,335,000 shares at an aggregate cost of $302.0 million as compared with 414,400 shares at an aggregate cost of $40.0 million in 2006. At March 31, 2007, 1,896,000 shares of common stock were remaining under the Corporation’s repurchase authorization.

In September 2006, the Corporation entered into two forward starting interest rate swap agreements (the “Swap Agreements”) related to $150.0 million of the Corporation’s anticipated refinancing of its $200.0 million 5.875% Notes due in 2008. The change in fair value of the Swap Agreements, net of income taxes, is recorded directly in shareholders’ equity as other comprehensive earnings/loss. At March 31, 2007, the fair value of the Swap Agreements was a liability of $1.6 million and was included in other noncurrent liabilities in the Corporation’s consolidated balance sheet. Other comprehensive earnings/loss for the three months ended March 31, 2007 included a gain of $202,000, net of tax, for the change in fair value of the Swap Agreements.

At March 31, 2007, commercial paper borrowings of $248.0 million were outstanding. Additionally, the Corporation’s $125.0 million 6.9% Notes will mature in August 2007.

During April 2007, the Corporation borrowed $100.0 million of money market notes at a weighted average interest rate of 5.43%. The money market notes matured through May 2, 2007.

On April 17, 2007, the Corporation entered into an amendment of its $250,000,000 five-year revolving credit agreement, which modified the leverage ratio covenant in the agreement. As modified, the covenant requires the Corporation’s ratio of consolidated debt to consolidated earnings before interest, taxes, depreciation, depletion and amortization (EBITDA), as defined, for the trailing twelve months to not exceed 2.75 to 1.00 as of the end of any fiscal quarter. The covenant has certain exceptions related to qualifying acquisitions, as defined.

On April 25, 2007, the Corporation issued $250.0 million of 6.25% Senior Notes due in 2037 and $225.0 million of Floating Rate Senior Notes due in 2010 (collectively, the “Notes”). The 6.25% Senior Notes may be redeemed in whole or in part prior to their maturity at a “make whole” redemption price. The Floating Rate Senior Notes bear interest at a rate equal to the three-month LIBOR plus 0.15% and may not be redeemed prior to maturity. Upon a change of control repurchase event, the Corporation will be required to make an offer to repurchase all outstanding Notes at a price in cash equal to 101% of the principal amount of the Notes, plus any accrued and unpaid interest to, but not including, the purchase date. The Notes, which are unsecured, were used to repay the Corporation’s outstanding commercial paper obligations ($248.0 million outstanding at March 31, 2007) and other short-term loans and are anticipated to be used to fund the repayment of its $125.0 million 6.9% Notes due in August 2007.

The management team and Board of Directors have focused on establishing prudent leverage targets that provide for value creation through strong operational performance, continued investment in internal growth opportunities, financial flexibility to support opportunistic and strategic acquisitions and a return of cash to shareholders through sustainable dividends and share repurchase programs while maintaining a solid investment grade rating. Given these parameters, in the ordinary course of business, the Corporation expects to manage its leverage within a range of 2.0 to 2.5 times consolidated debt to consolidated earnings before interest, taxes, depreciation, depletion and amortization (EBITDA), as defined by the underlying credit agreement.

Based on prior performance and current expectations, the Corporation’s management believes that cash flows from internally generated funds and its access to capital markets are expected to continue to be sufficient to provide the capital resources necessary to fund the operating needs of its existing businesses, cover debt service requirements, and allow for payment of dividends in 2007.

The Corporation may be required to obtain additional levels of financing in order to fund certain strategic acquisitions, if any such opportunities arise. Currently, the Corporation’s senior unsecured debt is rated “BBB+” by Standard & Poor’s and “Baa1” by Moody’s. The Corporation’s commercial paper obligations are rated “A-2” by Standard & Poor’s and “P-2” by Moody’s. While management believes its credit ratings will remain at an investment-grade level, no assurance can be given that these ratings will remain at those levels.

Contractual Obligations

Upon adoption of FIN 48 at January 1, 2007, the Corporation had gross unrecognized tax benefits, excluding interest, of $29.2 million. The Corporation anticipates settlement of $27.8 million with the taxing authorities in the upcoming twelve months and settlement of $1.4 million in one to three years.

ACCOUNTING CHANGES As discussed in Note 1 to the Consolidated Financial Statements, effective January 1, 2007, the Corporation adopted FIN 48 and reduced retained earnings by $1.4 million.

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, 2006, filed with the Securities and Exchange Commission on February 28, 2007. Management continues to evaluate its exposure to all operating risks on an ongoing basis.

OUTLOOK 2007 Based upon the strong first-quarter performance and other favorable developments, management continues to have a positive outlook for 2007. Aggregates product line pricing is expected to increase 10% to 11.5% for the year, reflecting continued supply constraints in many of the Corporation’s southeast and southwest market areas as well as the rapidly escalating replacement cost of strategically located mineral reserves. Demand for aggregates products is expected to be flat to down 2% with expectations of a softer construction market in the first half of 2007 mitigated by volume growth in the back half of 2007. Commercial and infrastructure construction is expected to increase in 2007, although not at the same rate as in 2006.

The delays in infrastructure spending in North Carolina and South Carolina are expected to continue throughout 2007; however, management continues to believe that the environment remains positive for pricing improvements and, combined with the Corporation’s strict adherence to cost management, it expects to be able to more than offset these infrastructure issues and report increased earnings. Management believes residential construction is likely to decline significantly in the first half of 2007 with the downturn beginning to moderate during the latter part of the year as same-on-same comparisons should become easier. Volume growth in other uses of aggregates products, including chemical grade stone used in controlling electric power plant emissions and railroad ballast, is expected to continue in 2007.

The Specialty Products segment, which includes magnesia chemicals, dolomitic lime and focused activity in structural composites, is expected to contribute $33 million to $36 million in pretax earnings in 2007 compared with $22 million in 2006. Management expects the magnesia chemicals business to continue to grow and demand for dolomitic lime from the steel industry to be flat or down slightly

Management has raised guidance for net earnings for the full-year 2007 to a range of $6.10 to $6.65 per diluted share. For the second quarter of 2007, management expects net earnings to range from $1.85 to $2.10 per diluted share. Both ranges include the impact of FIN 48.

You may also write or call the Corporation’s Corporate Secretary, who will provide copies of such reports.

Investors are cautioned that all statements in this Quarterly Report that relate to the future involve risks and uncertainties, and are based on assumptions that the Corporation believes in good faith are reasonable but which may be materially different from actual results. Forward-looking statements give the investor our expectations or forecasts of future events. You can identify these statements by the fact that they do not relate only to historical or current facts. They may use words such as “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” and other words of similar meaning in connection with future events or future operating or financial performance. Any or all of our forward-looking statements here and in other publications may turn out to be wrong.

Factors that the Corporation currently believes could cause actual results to differ materially from the forward-looking statements in this Quarterly Report on Form 10-Q include, but are not limited to, the level and timing of federal and state transportation funding, particularly in North Carolina, one of the Corporation’s largest and most profitable states, and in South Carolina, the Corporation’s fifth largest state as measured by 2006 Aggregates’ business net sales; levels of construction spending in the markets the Corporation serves; the severity of a continued decline in the residential construction market and the impact, if any, on commercial construction; unfavorable weather conditions, including hurricane activity; the volatility of fuel costs, most notably diesel fuel, liquid asphalt and natural gas; continued increases in the cost of repair and supply parts; logistical issues and costs, notably barge availability on the Mississippi River system and the availability of railcars and locomotive power to move trains to supply the Corporation’s Texas and Gulf Coast markets; continued strength in the steel industry markets served by the Corporation’s dolomitic lime products; successful development and implementation of the structural composite technological process and commercialization of strategic products for specific market segments to generate earnings streams sufficient enough to support the recorded assets of the structural composites product line; and other risk factors listed from time to time found in the Corporation’s filings with the Securities and Exchange Commission.

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. Since June 30, 2004, the Federal Reserve Board has increased the federal funds rate from 1.00% to 5.25% at March 31, 2007. This increase could affect the residential construction market, which accounted for approximately 17% of the Corporation’s aggregates product line shipments in 2006. 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 its temporary cash investments, including money market funds and overnight investments in Eurodollars; any outstanding commercial paper obligations; defined benefit pension plans; and energy costs. Additionally, the shareholders’ equity of the Corporation is affected by changes in the fair value of forward starting interest rate swap agreements.

Commercial Paper Obligations. The Corporation has a $250 million commercial paper program in which borrowings bear interest at a variable rate based on LIBOR. At March 31, 2007, commercial paper borrowings of $248.0 million were outstanding. As commercial paper borrowings bear interest at a variable rate, the Corporation has interest rate risk. The effect of a hypothetical 100 basis point increase in interest rates on borrowings of $248.0 million would increase interest expense by $2.5 million on an annual basis.

Pension Expense. The Corporation’s results of operations are affected by its pension expense. Assumptions that affect this expense include the discount rate and 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, 2006, filed with the Securities and Exchange Commission on February 28, 2007.

Energy Costs. Energy costs, including diesel fuel, natural gas and liquid asphalt, represent significant production costs for the Corporation. Increases in these costs generally are tied to energy sector inflation. In 2006, energy costs increased significantly, with fuel price increases lowering earnings per diluted share by $0.36. A hypothetical 10% change in the Corporation’s energy prices in 2007 as compared with 2006, assuming constant volumes, would impact 2007 pretax earnings by approximately $17.8 million.

Aggregate Risk for Interest Rates and Energy Sector Inflation. The pension expense for 2007 is calculated based on assumptions selected at December 31, 2006. Therefore, interest rate risk in 2007 is limited to the potential effect related to outstanding commercial paper, of which $248.0 million was outstanding at March 31, 2007. Assuming outstanding commercial paper borrowings of $248.0 million, the impact of a hypothetical increase in interest rates of 1% would increase interest expense and decrease pretax earnings by $2.5 million. Additionally, a 10% change in energy costs would impact annual pretax earnings by $17.8 million.

Forward Starting Interest Rate Swap Agreements. In September 2006, the Corporation entered into forward starting interest rate swap agreements (the “Swap Agreements”) for the anticipated refinancing of $150.0 million of its $200.0 million 5.875% Notes due in 2008. In accordance with Statement of Financial Accounting Standards No. 133 Accounting for Derivative Instruments and Hedging Activities (“FAS 133”), the fair values of the Swap Agreements are recorded as an asset or liability in the consolidated balance sheet. The change in fair value is recorded directly in shareholders’ equity, net of taxes, as other comprehensive earnings/loss. At March 31, 2007, the fair value of the Swap Agreements was a liability of $1.6 million and was included in other noncurrent liabilities in the Corporation’s consolidated balance sheet.

As a result of the Swap Agreements, the Corporation’s comprehensive earnings/loss will be affected by changes in the LIBOR rate. A hypothetical change in interest rates of 100 basis points would change other comprehensive earnings/loss by approximately $6.1 million, which is net of taxes of $3.9 million.

Item 4. Controls and Procedures

As of March 31, 2007, 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 March 31, 2007. There have been no significant changes in the Corporation’s internal controls or in other factors that could significantly affect the internal controls subsequent to March 31, 2007.
