COMMERCIAL METALS COMPANY AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1 — QUARTERLY FINANCIAL DATA

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States on a basis consistent with that used in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) for the year ended August 31, 2011, and include all normal recurring adjustments necessary to present fairly the consolidated balance sheets and statements of earnings, cash flows and stockholders’ equity for the periods indicated. These notes should be read in conjunction with such Form 10-K. The results of operations for the three month period are not necessarily indicative of the results to be expected for a full year.

NOTE 2 — SALES OF ACCOUNTS RECEIVABLE

The Company periodically contributes, and several of its subsidiaries periodically sell without recourse, certain eligible trade accounts receivable to the Company’s wholly-owned consolidated special purpose subsidiary, CMC Receivables, Inc. (“CMCRV”). CMCRV is structured to be a bankruptcy-remote entity and was formed for the sole purpose of buying and selling receivables generated by the Company. Depending on the Company’s level of financing needs, CMCRV will sell the trade accounts receivable in their entirety to a third party financial institution. The third party financial institution will advance up to a maximum of $100 million for all receivables and the remaining portion due to the Company will be deferred until the ultimate collection of the underlying receivables. On December 28, 2011, the Company amended its domestic sales of receivable facility which increased the capacity to $200 million and extended the maturity date to December 26, 2014. The Company accounts for sales to the financial institution as true sales and the cash advances for receivables are removed from the consolidated balance sheets and reflected as cash provided by operating activities. Additionally, the receivables program contains certain cross-default provisions whereby a termination event could occur if the Company defaulted under one of its credit arrangements. The covenants contained in this agreement are consistent with the credit facility fully described in Note 8, Credit Arrangements.

At November 30, 2011 and August 31, 2011, the Company sold $524.9 million and $557.0 million of receivables, respectively, to the third party financial institution, of which $50.0 million was received as advance payments in both periods. The remaining amounts of $474.9 million and $507.0 million, respectively, are the deferred purchase prices. The fair value of the deferred purchase prices at November 30, 2011 and August 31, 2011 were $463.7 million and $494.7 million, respectively, and are included as trade receivables on the consolidated balance sheets. The carrying value of the deferred purchase price approximates fair value due to the short-term nature of the underlying financial assets.

In addition to the domestic sale of accounts receivable program described above, the Company’s international subsidiaries in Europe and Australia periodically sell accounts receivable without recourse. These arrangements constitute true sales, and once the accounts are sold, they are no longer available to satisfy the Company’s creditors in the event of bankruptcy. Uncollected accounts receivable sold under these arrangements and removed from the consolidated balance sheets were $180.0 million and $132.2 million at November 30, 2011 and August 31, 2011, respectively. The Australian program contains financial covenants in which the subsidiary must meet certain coverage and tangible net worth levels, as defined. At November 30, 2011, the Australian subsidiary was not in compliance with these covenants. Commercial Metals Company provided a guarantee of the Australian subsidiary’s performance resulting in the financial covenants being waived at November 30, 2011. The guarantee will cease to be effective when the Australian subsidiary is in compliance with the financial covenants for two consecutive quarters.

During the three months ended November 30, 2011 and 2010, proceeds from the domestic and international sales of receivables were $528.9 million and $285.5 million, respectively, and cash payments to the owners of receivables were $481.1 million and $263.5 million, respectively. The Company is responsible for servicing the receivables for a nominal servicing fee. Discounts on domestic and international sales of accounts receivable were $1.7 million and $1.2 million for the three months ended November 30, 2011 and 2010, respectively. These discounts primarily represented the costs of funds and were included in selling, general and administrative expenses.

NOTE 3 — INVENTORIES

Inventories are stated at the lower of cost or market. Inventory cost for most domestic inventories is determined by the last-in, first-out method (“LIFO”). LIFO inventory reserves were $283.4 million and $307.3 million at November 30, 2011 and August 31, 2011, respectively. Inventory cost for international inventories and the remaining domestic inventories are determined by the first-in, first-out method (“FIFO”). The majority of the Company’s inventories are in the form of finished goods, with minimal work in process. At November 30, 2011 and August 31, 2011, $88.7 million and $107.7 million, respectively, were in raw materials.

NOTE 4 — GOODWILL AND OTHER INTANGIBLE ASSETS

The following table details the changes in the carrying amount of goodwill by reportable segment:

	Americas						International
(in thousands)	Recycling		Mills		Fabrication		Mills			Marketing and Distribution			Consolidated
Balance at August 31, 2011	$	7,267	$	295	$	57,144	$	3,092		$	9,840		$	77,638
Translation		—		—		—		(440	)		(434	)		(874	)
Balance at November 30, 2011	$	7,267	$	295	$	57,144	$	2,652		$	9,406		$	76,764

The total gross carrying amounts of the Company’s intangible assets that were subject to amortization were $47.7 million and $49.7 million at November 30, 2011 and August 31, 2011, respectively, and are included in other noncurrent assets. Aggregate amortization expense for intangible assets for the three months ended November 30, 2011 and 2010 was $1.5 million and $2.5 million, respectively.

NOTE 5 — SEVERANCE

During the three months ended November 30, 2011 and 2010, the Company recorded severance costs of $19.8 million and $0.4 million, respectively. The cost recorded during the first quarter of 2012 primarily relates to the Company’s discontinued operations. See Note 7, Discontinued Operations, for additional details.

NOTE 6 — DISPOSITIONS

During the first quarter of 2012, the Company completed the sale of two properties which were previously joist and deck locations. During the first quarter of 2011, CMC Construction Services, a division of a subsidiary of the Company, completed the sale of heavy forming and shoring equipment for approximately $35 million. Additionally, during the first quarter of 2011, the Company completed the sale of the majority of the joist assets. These transactions resulted in minimal gain or losses on sale.

NOTE 7 — DISCONTINUED OPERATIONS

During the first quarter of 2012, the Company announced its decision to exit its steel pipe manufacturing operations in Croatia (“CMCS”) by closure of the facility and sale of the assets. The Company has begun winding down operations and expects the backlog and liquidation of inventory to be completed in the second quarter of 2012. The Company determined that the decision to exit this business met the definition of a discontinued operation. As a result, this business has been presented as a discontinued operation for all periods. During the first quarter of 2012, the Company recorded severance costs of approximately $18 million associated with exiting the business. This business was in the International Mills segment.

During the second quarter of 2010, the Company’s Board approved a plan to exit the joist and deck business through the sale of those facilities. The Company determined that the decision to exit this business met the definition of a discontinued operation. As a result, this business has been presented as a discontinued operation for all periods. At November 30, 2011, the remaining assets consist of real property for three locations. The joist and deck business was in the Americas Fabrication segment.

8

As of November 30, 2011, the assets and liabilities of discontinued operations have been presented as held for sale and included in other current assets and accrued expenses and other payables on the consolidated balance sheets. Financial information for discontinued operations was as follows:

(in thousands)	November 30, 2011		August 31, 2011

	2011			2010

Loss before taxes		(27,003	)		(13,885	)

NOTE 8 — CREDIT ARRANGEMENTS

The Company’s revolving credit facility of $400 million has a maturity date of November 24, 2012. On December 27, 2011, the Company entered into a third amended and restated credit agreement which reduced the revolving credit facility to $300 million and extended the maturity date to December 27, 2016. The maximum facility can be increased to $400 million with the consent of all parties. Under the current credit facility, the Company is required to maintain a minimum interest coverage ratio of not less than 2.50 to 1.00 for the twelve month cumulative period ended November 30, 2011 and for each fiscal quarter on a rolling twelve month cumulative period thereafter. At November 30, 2011, the Company’s interest coverage ratio was 3.27 to 1.00. The agreement also requires the Company to maintain a debt to capitalization ratio covenant not greater than 0.60 to 1.00. At November 30, 2011, the Company’s debt to capitalization ratio was 0.53 to 1.00. The agreement provides for interest based on LIBOR, Eurodollar or Bank of America’s prime rate. The Company did not have any amounts outstanding on the revolving credit facility at November 30, 2011 or August 31, 2011.

The Company has numerous uncommitted credit facilities available from domestic and international banks. These credit facilities are used, in general, to support import letters of credit (including accounts payable settled under bankers’ acceptances), foreign exchange transactions and short-term advances which are priced at market rates.

Long-term debt, including the net effect of interest rate swap revaluation adjustments, was as follows:

(in thousands)	Weighted Average Interest Rate at November 30, 2011			November 30, 2011		August 31, 2011
5.625% notes due November 2013		3.8	%	$	206,177	$	207,752

Less current maturities					3,697		58,908
				$	1,152,869	$	1,167,497

Interest on the notes is payable semiannually.

During the third quarter of 2011, the Company entered into an interest rate swap transaction to hedge the fair value changes on its 6.50% notes due July 2017 (“2017 Notes”). During the third quarter of 2010, the Company entered into interest rate swap transactions on its 5.625% notes due November 2013 (“2013 Notes”) and 7.35% notes due August 2018 (“2018 Notes”). The swap transactions were designated as fair value hedges at inception and effectively convert all fixed-rate interest to floating rate interest on the Company’s 2013 Notes, and effectively convert fixed-rate interest to floating rate interest with respect to $300 million in principal amount on each of the 2017 Notes and the 2018 Notes and have termination dates of November 15, 2013, July 15, 2017 and August 15, 2018, respectively. Under the terms of the swaps, the Company pays the floating LIBOR plus 303 basis points with respect to the 2013 Notes, LIBOR plus 374 basis points with respect to the 2017 Notes and LIBOR plus 367 basis points with respect to the 2018 Notes and receives payments identical to the hedged item fixed rates.

9

The CMCS financing agreement was used for capital expenditures and other uses. The note has scheduled principal and interest payments in semiannual installments. During the first quarter of 2012, the Company presented CMCS as a discontinued operation. As a result, the CMCS financing agreement was classified as held for sale and included in accrued expenses and other payables on the consolidated balance sheet. The outstanding balance at November 30, 2011 was $17.3 million. See Note 7, Discontinued Operations, for additional information.

The CMC Zawiercie (“CMCZ”) term note was repaid on October 20, 2011. Subsequently, CMCZ entered into current uncommitted credit facilities of $76.0 million with several banks, which expire in the first quarter of 2013. At November 30, 2011, $42.3 million was outstanding under these facilities and included in notes payable on the consolidated balance sheets. The weighted average interest rate on these facilities was approximately 5.5% at November 30, 2011.

Interest of $0.4 million and $0.2 million was capitalized in the cost of property, plant and equipment constructed for the three months ended November 30, 2011 and 2010, respectively. Interest of $4.4 million and $5.0 million was paid for the three months ended November 30, 2011 and 2010, respectively.

NOTE 9 — DERIVATIVES AND RISK MANAGEMENT

The Company’s worldwide operations and product lines expose it to risks from fluctuations in metals commodity prices, foreign currency exchange rates, natural gas prices and interest rates. One objective of the Company’s risk management program is to mitigate these risks using derivative instruments. The Company enters into metal commodity futures and forward contracts to mitigate the risk of unanticipated declines in gross margin due to the volatility of the commodities’ prices, enters into foreign currency forward contracts which match the expected settlements for purchases and sales denominated in foreign currencies and enters into natural gas forward contracts to mitigate the risk of unanticipated changes in operating cost due to the volatility of natural gas prices. When sales commitments to customers include a fixed price freight component, the Company occasionally enters into freight forward contracts to minimize the effect of the volatility of ocean freight rates. The Company enters into interest rate swap contracts to maintain a portion of the Company’s debt obligations at variable interest rates. These interest rate swap contracts, under which the Company has agreed to pay variable rates of interest and receive fixed rates of interest, are designated as fair value hedges of fixed-rate debt.

At November 30, 2011, the Company’s notional value of its foreign currency contract commitments was $298 million and interest rate swap contract commitments was $800 million.

The following table provides commodity contract commitments as of November 30, 2011:

Commodity	Long/Short	Total
Aluminum	Long		5,175 MT
Aluminum	Short		3,225 MT
Copper	Long		848 MT
Copper	Short		5,636 MT
Zinc	Long		36 MT
Natural Gas	Long		160,000 MMBtu

• MT = Metric Ton

• MMBtu = One million British thermal units

The Company designates only those contracts which closely match the terms of the underlying transaction as hedges for accounting purposes. These hedges resulted in substantially no ineffectiveness in the statements of earnings, and there were no components excluded from the assessment of hedge effectiveness for the three months ended November 30, 2011 and 2010. Certain of the foreign currency and commodity contracts were not designated as hedges for accounting purposes, although management believes they are essential economic hedges.

The following tables summarize activities related to the Company’s derivative instruments and hedged (underlying) items recognized within the statements of earnings (in thousands):

Derivatives Not Designated as Hedging Instruments	Location	Three Months Ended November 30,
		2011			2010
Commodity	Cost of goods sold	$	3,577		$	(10,286	)

Foreign exchange	SG&A expenses		(7,159	)		(3,324	)
Loss before taxes		$	(3,923	)	$	(13,048	)

The Company’s fair value hedges are designated for accounting purposes with gains and losses on the hedged (underlying) items offsetting the gain or loss on the related derivative transaction. Hedged (underlying) items relate to firm commitments on commercial sales and purchases, capital expenditures and fixed-rate debt obligations. As of November 30, 2011, fair value hedge accounting for interest rate swap contracts increased the carrying value of debt instruments by $45.6 million.

Derivatives Designated as Fair Value Hedging Instruments	Location	Three Months  Ended November 30,

Interest rate	Interest expense		(1,205	)		(21,555	)
Loss before taxes		$	(3,784	)	$	(13,669	)

The Company recognizes the impact of actual and estimated net periodic settlements of current interest on active interest rate swaps as adjustments to interest expense. The Company recorded reductions to interest expense related to interest rate swaps of $4.2 million and $3.3 million for the three months ended November 30, 2011 and 2010, respectively. These amounts represent the net of the Company’s periodic variable-rate interest obligations and the swap counterparty’s fixed-rate interest obligations. The Company’s variable-rate obligations are based on a spread from the six-month LIBOR.

As of November 30, 2011, all of the Company’s derivative instruments designated to hedge exposure to the variability in future cash flows of the forecasted transactions will mature within twelve months.

All of the instruments are highly liquid, and not entered into for trading purposes.

NOTE 10 — FAIR VALUE

The Company has established a fair value hierarchy which prioritizes the inputs to valuation techniques used to measure fair value into three levels. These levels are determined based on the lowest level input that is significant to the fair value measurement.

The following table summarizes information regarding the Company’s financial assets and financial liabilities that were measured at fair value on a recurring basis:

			Fair Value Measurements at Reporting Date Using
(in thousands)	November 30, 2011		Quoted Prices in Active  Markets for Identical Assets (Level 1)		Significant Other Observable  Inputs (Level 2)		Significant Unobservable  Inputs (Level 3)

* The Company provides a nonqualified benefit restoration plan to certain eligible executives equal to amounts that would have been available under tax qualified ERISA plans but for limitations of ERISA, tax laws and regulations. Though under no obligation to fund this plan, the Company has segregated assets in a trust. The plan assets and liabilities consist of securities included in various mutual funds.

12

The Company’s long-term debt is predominantly publicly held. The fair value was approximately $1.13 billion at November 30, 2011 and $1.24 billion at August 31, 2011. Fair value was determined by indicated market values.

NOTE 11 — INCOME TAXES

The Company’s effective income tax rate for continuing operations for the three months ended November 30, 2011 and 2010 was (320.7)% and 31.1%, respectively. The effective tax rate from discontinued operations for the three months ended November 30, 2011 and 2010 was 35.9% and (1.9)%, respectively.

During the three months ended November 30, 2011, the Company recognized a tax loss in the amount of $291 million related to its investments in its Croatian company. As a result, a tax benefit of $102 million was recorded from these losses in the first quarter of 2012 in continuing operations which is the primary reason for the variance in the tax rate from continuing operations in first quarter of 2011. The Company will report and disclose the losses on these investments on its U.S. tax return as ordinary worthless stock and bad debt deductions.

The Company made net payments of $12.5 million and had net refunds of $1.9 million for income taxes during the three months ended November 30, 2011 and 2010, respectively.

The reserve for unrecognized tax benefits relating to the accounting for uncertainty in income taxes was $10.0 million and $20.4 million, exclusive of interest and penalties, as of November 30, 2011 and 2010, respectively.

The Company’s policy classifies interest recognized on an underpayment of income taxes and any statutory penalties recognized on a tax position as tax expense and the balances at the end of a reporting period are recorded as part of the current or noncurrent reserve for uncertain income tax positions. For the three months ended November 30, 2011, before any tax benefits, the Company recorded immaterial amounts of accrued interest and penalties on unrecognized tax benefits.

During the next twelve months, it is reasonably possible that the statute of limitations may lapse pertaining to positions taken by the Company in prior year tax returns or that income tax audits in various taxing jurisdictions could be finalized. As a result, the total amount of unrecognized tax benefits may decrease, which would reduce the provision for taxes on earnings by an immaterial amount.

The following is a summary of tax years subject to examination:

U.S. Federal - 2009 and forward

U.S. States - 2006 and forward

Foreign - 2005 and forward

The Company is currently under examination by the Internal Revenue Service and several U.S. states. We believe our recorded tax liabilities as of November 30, 2011 sufficiently reflect the anticipated outcome of these examinations.

NOTE 12 — SHARE-BASED COMPENSATION

The Company recognizes share-based compensation at fair value in the financial statements. The fair value of each share-based award is estimated at the date of grant using either the Black-Scholes pricing model or a binomial model. Total compensation cost is amortized over the requisite service period using the accelerated method of amortization for grants with graded vesting or using the straight-line method for grants with cliff vesting. The Company recognized share-based compensation of $3.9 million and $2.1 million for the three months ended November 30, 2011 and 2010, respectively, as a component of selling, general and administrative expenses. At November 30, 2011, the Company had $38.3 million of total unrecognized pre-tax compensation cost related to non-vested share-based compensation arrangements. This cost is expected to be recognized over three years.

13

Combined information for shares subject to options and stock appreciation rights (“SARs”), excluding the cash component, for the three months ended November 30, 2011 was as follows:

	Number			Weighted Average Exercise Price		Weighted Average Remaining Contractual Life (Years)
Outstanding at September 1, 2011		2,807,498		$	27.45
Granted		825,655			11.60
Forfeited/Expired		(17,730	)		28.28
Outstanding at November 30, 2011		3,615,423		$	23.83		3.5
Exercisable at November 30, 2011		2,621,768		$	28.19		2.3

Information for restricted stock awards and performance-based restricted units (“PSUs”), excluding the cash component, for the three months ended November 30, 2011 was as follows:

	Number			Weighted  Average Grant-Date Fair Value
Outstanding at September 1, 2011		2,394,140		$	13.44
Granted		412,821		$	10.17
Vested		(8,717	)		14.98
Forfeited		(24,301	)		12.49
Outstanding at November 30, 2011		2,773,943		$	12.96

During the first quarter of 2012, the Compensation Committee (the “Committee”) of the Board of Directors approved a grant of restricted stock units (“RSUs”), SARs and PSUs to employees. The PSUs will vest upon the achievement of certain target levels of the performance goals and objectives of the Company over the performance period of approximately three years. The actual number of PSUs granted will be based on the level of achievement. Upon achievement of any of the performance goals, the awards will be paid out in cash. Additionally, a portion of the RSUs and SARs are settled in cash. The Company accounts for the cash component of stock awards as a liability award and the liability is adjusted at each reporting period based on the share price of Company’s common stock.

NOTE 13 — STOCKHOLDERS’ EQUITY AND EARNINGS PER SHARE ATTRIBUTABLE TO CMC

In calculating earnings per share, there were no adjustments to net earnings to arrive at earnings for any periods presented. The reconciliation of the denominators of the earnings per share calculations was as follows:

	Three Months Ended November 30,
	2011		2010
Shares outstanding for basic earnings per share		115,530,545		114,319,017
Effect of dilutive securities:
Stock based incentive/purchase plans		918,938		904,676
Shares outstanding for diluted earnings per share		116,449,483		115,223,693

For the three months ended November 30, 2011 and 2010, SARs with total share commitments of 2.7 million and 2.3 million, respectively, were antidilutive and therefore excluded from the calculation of diluted earnings per share. All stock options and SARs expire by 2018.

The Company’s restricted stock is included in the number of shares of common stock issued and outstanding, but omitted from the basic earnings (loss) per share calculation until the shares vest.

The Company did not purchase any shares during the first quarter of 2012 and had remaining authorization to purchase 8,259,647 shares of its common stock at November 30, 2011.

NOTE 14 — COMMITMENTS AND CONTINGENCIES

See Note 16, Commitments and Contingencies, to the consolidated financial statements in the Annual Report on Form 10-K for the year ended August 31, 2011 relating to environmental and other matters. There have been no significant changes to the matters noted therein. In the ordinary course of conducting its business, the Company becomes involved in litigation, administrative proceedings and governmental investigations, including litigation, proceedings and investigations relating to environmental matters. Management believes that adequate provisions have been made in the consolidated financial statements for the potential impact of these contingencies, and that the outcomes will not significantly impact the results of operations, financial position or cash flows of the Company.

NOTE 15 — BUSINESS SEGMENTS

The Company’s reportable segments are based on strategic business areas, which offer different products and services. These segments have different lines of management responsibility as each business requires different marketing strategies and management expertise.

The Company structures the business into the following five segments: Americas Recycling, Americas Mills, Americas Fabrication, International Mills and International Marketing and Distribution. The Americas Recycling segment consists of the scrap metal processing and sales operations primarily in Texas, Florida and the southern United States. The Americas Mills segment includes the Company’s domestic steel mills, including the scrap processing facilities that directly support these mills, and the copper tube minimill. The copper tube minimill is aggregated with the Company’s steel mills because it has similar economic characteristics. The Americas Fabrication segment consists of the Company’s rebar fabrication operations, fence post manufacturing plants and construction-related and other products facilities. The International Mills segment includes the minimill and recycling operations in Poland and fabrication operations in Europe, which have been presented as a separate segment because the economic characteristics of their markets and the regulatory environment in which they operate differ from the Company’s domestic mills and rebar fabrication operations. International Marketing and Distribution includes international operations for the sales, distribution and processing of steel products, ferrous and nonferrous metals and other industrial products. Additionally, the International Marketing and Distribution segment includes the Company’s U.S.-based trading and distribution divisions, CMC Cometals and CMC Cometals Steel. The international distribution operations consist only of physical transactions and not positions taken for speculation. Corporate contains expenses of the Company’s corporate headquarters and interest expense relating to its long-term public debt and commercial paper program.

The financial information presented for the International Mills segment excludes the minimill in Croatia and the financial information presented for the Americas Fabrication segment excludes its joist and deck fabrication operations. These operations have been classified as discontinued operations in the consolidated statements of earnings. See Note 7, Discontinued Operations, for more detailed information.

The Company uses adjusted operating profit (loss) to measure segment performance. Intersegment sales are generally priced at prevailing market prices. Certain corporate administrative expenses are allocated to segments based upon the nature of the expense.

NOTE 16 — RELATED PARTY TRANSACTIONS

One of the Company’s international subsidiaries had a marketing and distribution agreement with a key supplier of which the Company owns an 11% interest. This marketing and distribution agreement expired during the second quarter of 2011. As a result, there were no related party transactions during the first quarter of 2012. During the first quarter of 2011, net sales to this related party were $98.1 million and total purchases were $107.0 million.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and the notes thereto, which are included in this report, and our audited consolidated financial statements and the notes thereto, which are included in our Annual Report on Form 10-K for the fiscal year ended August 31, 2011. This discussion contains or incorporates by reference “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the Private Securities Litigation Reform Act of 1995. These forward-looking statements are not historical facts, but rather are based on expectations, estimates, assumptions and projections about our industry, business and future financial results, based on information available at the time this report is filed with the Securities and Exchange Commission or, with respect to any document incorporated by reference, available at the time that such document was prepared. Our actual results could differ materially from the results contemplated by these forward-looking statements due to a number of factors, including those identified in the section entitled “Forward-Looking Statements” in this Item 2 of this Quarterly Report on Form 10-Q and in the section entitled “Risk Factors” in Item 1A of our Annual Report on Form 10-K for the fiscal year ended August 31, 2011. We do not assume any obligation to update or revise any forward-looking statements to reflect changed assumptions, the occurrence of anticipated or unanticipated events, new information or circumstances or otherwise, except as required by law.

CRITICAL ACCOUNTING POLICIES

There have been no material changes to our critical accounting policies as set forth in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, included in our Annual Report on Form 10-K filed with the SEC for the year ended August 31, 2011.

CONSOLIDATED RESULTS OF OPERATIONS

	Three Months Ended November 30,				Increase (Decrease)
(in millions)	2011		2010		%
Net sales*	$	1,986.8	$	1,775.1		12	%
Earnings from continuing operations		125.0		14.9		739	%
Adjusted EBITDA		55.5		66.6		(17	)%

* Excludes divisions classified as discontinued operations.

In the table above, we have included a financial statement measure that was not derived in accordance with accounting principles generally accepted in the United States (“GAAP”). We use adjusted EBITDA (earnings before interest expense, income taxes, depreciation, amortization and non-cash impairment charges) as an operational performance measure. In calculating adjusted EBITDA, we exclude our largest recurring non-cash charge, depreciation and amortization as well as impairment charges. Adjusted EBITDA compares results without the need to adjust for Federal, state and local taxes, which have considerable variation between domestic jurisdictions. Tax regulations in international operations add additional complexity. Also, we exclude interest cost in our calculation of adjusted EBITDA. The results are, therefore, without consideration of financing alternatives of capital employed. We use adjusted EBITDA as one guideline to assess our unleveraged performance return on our investments. Adjusted EBITDA is also the target benchmark for our long-term cash incentive performance plan for management and part of a debt compliance test for our revolving credit agreement. Reconciliations from net earnings from continuing operations to adjusted EBITDA are provided below:

	Three Months  Ended November 30,						Increase (Decrease)
(in millions)	2011			2010			%
Earnings from continuing operations	$	125.0		$	14.9			739	%
Less net earnings attributable to noncontrolling interests		—			(0.1	)		100	%
Interest expense		16.3			17.9			(9	)%
Income taxes (benefit)		(95.3	)		6.7			(1,522	)%
Depreciation, amortization and impairment charges		34.5			39.5			(13	)%
Adjusted EBITDA from continuing operations	$	80.5		$	78.9			2	%
Adjusted EBITDA from discontinued operations		(25.0	)		(12.3	)		(103	)%
Adjusted EBITDA	$	55.5		$	66.6			(17	)%

Our adjusted EBITDA does not include interest expense, income taxes, depreciation, amortization and impairment charges. Because we have borrowed money in order to finance our operations, interest expense is a necessary element of our costs and our ability to generate revenues. Because we use capital assets, depreciation and amortization are also necessary elements of our costs. Impairment charges, when necessary, accelerate the write-off of fixed assets that would otherwise have been accomplished by periodic depreciation charges. Also, the payment of income taxes is a necessary element of our operations. Therefore, any measures that exclude these elements have material limitations. To compensate for these limitations, we believe that it is appropriate to consider both net earnings determined under GAAP, as well as adjusted EBITDA, to evaluate our performance. Also, we separately analyze any significant fluctuations in interest expense, depreciation, amortization, impairment charges and income taxes.

The following factors had a significant financial impact during our first quarter of 2012 as compared to the same period of 2011, or are expected to be significant for our future operations:

• During the first quarter of 2012, we announced the exit of our steel pipe manufacturing operations in Croatia (“CMCS”) by closure of the facility and sale of the assets. This business was previously included in the International Mills segment and is now included in discontinued operations. Production in the melt shop and rolling mill ceased during the first quarter of 2012 and final shipments will be made during the second quarter.

• During the first quarter of 2012, we recognized a tax benefit of $102 million in continuing operations related to ordinary worthless stock and bad debt deductions from our investment in CMCS.

• Net sales of the Americas Recycling segment increased $39.0 million, or 10%, and adjusted operating profit increased $12.6 million during the first quarter of 2012 as compared to the prior year’s first quarter. The improvement in adjusted operating profit is primarily due to a swing to LIFO income of $12.8 million.

• Net sales of the Americas Mills segment increased $90.1 million, or 21%, and adjusted operating profit increased $23.8 million from the prior year’s first quarter. The improvement in adjusted operating profit was primarily due to increased shipments and metal margins and an increase in LIFO income of $14.7 million.

• Net sales of the Americas Fabrication segment increased $32.0 million, or 11%, and adjusted operating loss decreased $14.6 million to an adjusted operating loss of $7.4 million from the prior year’s first quarter primarily due to higher selling prices and improved margins.

• Net sales of the International Mills segment increased $79.0 million, or 36%, and adjusted operating profit increased $3.4 million from the prior year’s first quarter primarily due to higher shipments.

• Net sales of International Marketing and Distribution segment increased $64.2 million, or 10%, but adjusted operating results decreased $28.3 million to an adjusted operation loss of $4.1 million from the prior year’s first quarter primarily due to losses on iron ore contracts.

• We recorded consolidated pre-tax LIFO income of $23.9 million for the first quarter of 2012 compared to pre-tax LIFO expense of $5.7 million for the first quarter of 2011.

SEGMENT OPERATING DATA

Unless otherwise indicated, all dollar amounts below are calculated before income taxes. Financial results for our reportable segments are consistent with the basis and manner in which we internally disaggregate financial information for the purpose of making operating decisions. See Note 15, Business Segments, to the consolidated financial statements.

We use adjusted operating profit (loss) to compare and evaluate the financial performance of our segments. Adjusted operating profit (loss) is the sum of our profit (loss) before income taxes and financing costs. The following tables show net sales and adjusted operating profit (loss) by business segment:

LIFO Impact on Adjusted Operating Profit (Loss) LIFO is an inventory costing method that assumes the most recent inventory purchases or goods manufactured are sold first. This results in current sales prices offset against current inventory costs. In periods of rising prices it has the effect of eliminating inflationary profits from operations. In periods of declining prices it has the effect of eliminating deflationary losses from operations. In either case the goal is to reflect economic profit. The table below reflects LIFO income or (expense) representing decreases or (increases) in the LIFO inventory reserve. International Mills is not included in this table as it uses FIFO valuation exclusively for its inventory:

Americas Recycling During the first quarter of 2012, this segment reported an increase in net sales and adjusted operating profit as compared to the first quarter of 2011. The improvement in adjusted operating profit was primarily the result of LIFO income of $10.6 million in the first quarter of 2012 as compared to LIFO expense of $2.2 million in the first quarter of 2011. Ferrous pricing and volumes were higher in the first quarter of 2012 as compared to first quarter of 2011 as a result of improved demand. We exported 5% of our ferrous scrap tonnage and 35% of our nonferrous scrap tonnage during the quarter. Our new shredders in Texas and Oklahoma will be operational in the second quarter of 2012.

The following table reflects our Americas Recycling segment’s average selling prices per ton and tons shipped (in thousands):

Ferrous tons shipped		538		495		43			9	%
Nonferrous tons shipped		60		63		(3	)		(5	)%

Americas Mills We include our five domestic steel mills, including the scrap locations which directly support the steel mills, and our copper tube minimill in our Americas Mills segment.

Within the segment, adjusted operating profit for our five domestic steel mills was $58.4 million for the first quarter of 2012 compared to an adjusted operating profit of $29.1 million for the prior year’s first quarter. The quarterly adjusted operating profit increased due to volume and margin improvements in our merchant and billet products. We recorded LIFO income of $0.9 million in the first quarter of 2012 as compared to LIFO expense of $10.5 million last year. Our mills operated at 78% of capacity in the first quarter of

20

2012, an increase from the 72% in the first quarter of 2011. Shipments included 120 thousand tons of billets in the first quarter of 2012 as compared to 90 thousand tons of billets in the first quarter of 2011.

The table below reflects our domestic steel mills’ operating statistics (in thousands) and average prices per short ton:

Average metal margin		322		293		29		10	%
Average ferrous scrap purchase price		344		280		64		23	%

Our copper tube minimill recorded an adjusted operating loss of $0.5 million during the first quarter of 2012, a decrease of $5.5 million from the adjusted operating profit of $5.0 million recorded in the first quarter of 2011. The decline in adjusted operating results was primarily due to lower sales and margins as the decline in sales prices outpaced the scrap purchase cost. The decrease in adjusted operating results was partially offset by an increase in LIFO income of $3.2 million.

The table below reflects our copper tube minimill’s operating statistics:

	Three Months  Ended November 30,				Decrease

Pounds shipped		9.3		10.6		(1.3	)		(12	)%
Pounds produced		7.8		9.7		(1.9	)		(20	)%

Americas Fabrication During the first quarter of 2012, this segment’s adjusted operating loss showed an improvement of $14.6 million over the prior year’s first quarter and recorded an adjusted operating loss of $7.4 million. Margins recovered modestly during the first quarter of 2012 as mill prices to the downstream fabricating units stabilized, allowing for the release of prior contract loss accruals. Backlog continued to grow both in tonnage and pricing. The overall market remains weak for fabricated steel with credit availability, state and federal funding capacity and unemployment trends adversly affecting the launch of new projects. Results were positively impacted by an increase in LIFO income of $3.5 million in the first quarter of 2012 as compared to the first quarter of 2011. The composite average fabrication selling price was $880 per ton during the first quarter of 2012, 14% higher than during last year’s first quarter.

International Mills We include the mimimill, CMC Zawiercie (“CMCZ”), and recycling and fabrication operations in Poland in our International Mills segment. During the first quarter of 2012, this segment’s adjusted operating profit was $9.8 million as compared to an adjusted operating profit of $6.4 million in the first quarter of last year. The mill benefited from a continued strong Polish economy which drove higher volumes and pricing in the first quarter of 2012. Additionally, the mill experienced an improved product mix from

21

sales of merchant bar from the flexible rolling mill. Shipments included 79 thousand tons of billets compared to 50 thousand tons of billets in the prior year.

International Marketing and Distribution During the first quarter of 2012, this segment reported an increase in net sales of 10% but reported an adjusted operating loss of $4.1 million as compared to an adjusted operating profit of $24.2 million in the first quarter of 2011. The decrease in adjusted operating results was primarily due to charges incurred on iron ore purchase contracts as our raw material marketing business was adversely impacted by the deterioration of iron ore prices during the first quarter of 2012. Australia’s adjusted operating results shifted to a small adjusted operating loss in the first quarter of 2012 as compared to an adjusted operating profit in the prior year’s first quarter as the Australian economy remains sluggish. Our recently acquired operation in Australia, G.A.M. Steel, was profitable during the first quarter.

Corporate Our corporate expenses increased $12.7 million in the first quarter of 2012 to $23.3 million primarily due to higher employee benefits including retirement and severance costs, professional services and information technology costs from new implementations.

Interest Expense Our interest expense decreased by $1.6 million to $16.3 million during the first quarter of 2012 as compared to the first quarter of 2011, primarily from the favorable impact of interest rate swap transactions.

Income Taxes Our effective tax rate from continuing operations for the quarter ended November 30, 2011 was a favorable (320.7)% as compared to 31.1% in the first quarter of 2011. Our effective tax rate for the first quarter of 2012 varies from our statutory rate primarily due to a tax benefit of $102 million for ordinary worthless stock and bad debt deductions on our investment in CMCS.

Discontinued Operations During the first quarter of 2012, we classified CMCS as a discontinued operation. Adjusted operating loss was $26.6 million in the first quarter of 2012 as compared to $13.4 million in the first quarter of 2011. We recorded severance costs of approximately $18 million in the first quarter of 2012 in connection with the closure of CMCS. We expect expenses related to discontinued operations to be significantly reduced in future quarters.

OUTLOOK

Our second quarter is historically our slowest quarter due to weather-related slowdowns in construction and holiday seasons around the world. In the second quarter of 2012, we expect scrap prices to rise. Our recycling operations should benefit from the increase in scrap prices but our mills and fabrication operations could temporarily experience metal margin compression. Our backlog remains somewhat higher than the fourth quarter of 2011 with improved prices. We remain focused on and continue to make good progress in improving our operating cost structure and cash flows.

LIQUIDITY AND CAPITAL RESOURCES

See Note 8 — Credit Arrangements, to the consolidated financial statements.

22

We believe we have adequate access to sources of contractually committed borrowings and other available credit facilities.

While we believe the lending institutions participating in our credit arrangements are financially capable, recent events in the global credit markets, including the failure, takeover or rescue by various government entities of major financial institutions, have created uncertainty of credit availability to an extent not experienced in recent decades. Additionally, changes by any rating agency to our credit rating can negatively impact our liquidity and increase our cost of borrowing.

The table below reflects our sources, facilities and availability of liquidity and capital resources as of November 30, 2011 (dollars in thousands):

	Total Facility		Availability
Cash and cash equivalents	$	228,103	$	—
Revolving credit facility*		400,000		400,000
Domestic receivable sales facility		100,000		50,000
International accounts receivable sales facilities		201,412		21,384
Bank credit facilities — uncommitted		813,955		425,408
Notes due from 2013 to 2018		1,100,000		**
CMCZ credit facilities		76,000		33,666
Trade financing arrangements		**		As required
Equipment notes		10,937		**

* The availability under the revolving credit agreement may be limited by the debt to capitalization ratio covenant.

** We believe we have access to additional financing and refinancing, if needed.

On December 27, 2011, we entered into a third amended and restated credit agreement which reduced the revolving credit facility to $300 million and extended the maturity date five years. The maximum credit facility can be increased to $400 million with the consent of all parties. On December 28, 2011, we amended our domestic sales of receivable facility which increased the capacity from $100 million to $200 million and extended the maturity date three years.

On October 20, 2011, we repaid our CMCZ term note and subsequently entered into current uncommitted credit facilities of PLN 255 million ($76.0 million) with several banks which expire in October and November of 2012. At November 30, 2011, we had PLN 142 million ($42.3 million) outstanding under these facilities.

We utilize uncommitted credit facilities to meet short-term working capital needs. Our uncommitted credit facilities primarily support import letters of credit (including accounts payable settled under bankers’ acceptances), foreign exchange transactions and short-term advances.

Our 5.625% $200 million notes due November 2013, 6.50% $400 million notes due July 2017 and our 7.35% $500 million notes due August 2018 require only payments of interest until maturity. We expect cash from operations to be sufficient to meet all interest and principal payments due within the next twelve months, and we believe we will be able to obtain additional financing or refinance these notes when they mature.

Certain of our financing agreements include various financial covenants. Our revolving credit facility requires us to maintain a minimum interest coverage ratio (adjusted EBITDA to interest expense) of not less than 2.50 to 1.00 for the twelve month cumulative period ended November 30, 2011 and for each fiscal quarter on a rolling twelve month cumulative period thereafter. At November 30, 2011, our interest coverage ratio was 3.27 to 1.00. The debt to capitalization ratio covenant under the agreement requires us to maintain a ratio not greater than 0.60 to 1.00. At November 30, 2011, our debt to capitalization ratio was 0.53 to 1.00. The revolving credit facility is used as an alternative source of liquidity. Our public debt does not contain any such covenants.

We regularly maintain a substantial amount of accounts receivable. We actively monitor our accounts receivable and record allowances as soon as we believe accounts are uncollectible based on current market conditions and customers’ financial condition. Continued pressure on the liquidity of our customers could result in additional reserves as we make our assessments in the future. We use credit insurance both in the U.S. and internationally to mitigate the risk of customer insolvency. We estimate the amount of credit insured receivables (and those covered by export letters of credit) was approximately 60% of total receivables at November 30, 2011.

23

For added flexibility, we may sell certain accounts receivable both in the U.S. and internationally. See Note 2, Sales of Accounts Receivable, to the consolidated financial statements. Our domestic sale of receivables program contains certain cross-default provisions whereby a termination event could occur should we default under another credit arrangement, and contains covenants that conform to the same requirements contained in our revolving credit agreement.

Cash Flows Our cash flows from operating activities primarily result from sales of steel and related products, and to a lesser extent, sales of nonferrous metal products. We also sell and rent construction-related products and accessories. We have a diverse and generally stable customer base. We use futures or forward contracts as needed to mitigate the risks from fluctuations in foreign currency exchange rates and metal commodity prices. See Note 9, Derivatives and Risk Management, to the consolidated financial statements.

During the first quarter of 2012, we generated $38.1 million of net cash flows from operating activities as compared to using $5.6 million in the first quarter of 2011. During the first quarter of 2012, we generated more cash than during the same period in 2011 from fluctuations in working capital. Significant fluctuations in working capital were as follows:

• Accounts receivable — accounts receivable decreased during the first quarter of 2012 as sales and pricing declined during November 2011. Additionally, we sold more receivables under our domestic and international sale of receivables programs during the first quarter of 2012 as compared to the same period in the prior year.

• Accounts payable — more cash was used in the first quarter of 2012 as accounts payable increased at the end of fiscal year 2011 due to higher volume.

During the first quarter of 2012, we used $23.8 million of net cash flows from investing activities as compared to generating $38.1 million during the first quarter of 2011. We invested $29.9 million in property, plant and equipment during the first quarter of 2012, an increase of $18.0 million over the first quarter of 2011. Additionally, proceeds from property, plant and equipment were $7.0 million in the first quarter of 2012, a decrease of $44.5 million over the first quarter of 2011. During the first quarter of 2011, we sold certain assets of our joist business and sold the forms of our heavy forms rental business.

We expect our total capital budget for fiscal 2012 to be approximately $140 million. We regularly assess our capital spending and reevaluate our requirements based on current and expected results.

During the first quarter of 2012, we used $1.0 million of net cash flows from financing activities as compared to using $50.1 million during the first quarter of 2011. The change was primarily due to increased documentary letters of credit which provided additional positive cash flow of $121.7 million during the first quarter of 2012. This was offset by a decrease in proceeds from long-term and short-term debt of $71.9 million. Our cash dividends remained consistent at approximately $14 million for both periods.

Our contractual obligations for the next twelve months of approximately $871 million are typically expenditures with normal revenue producing activities. We believe our cash flows from operating activities and debt facilities are adequate to fund our ongoing operations and planned capital expenditures.

Total contractual cash obligations	$	2,517,449	$	870,716	$	461,096	$	159,085	$	1,026,552

* We have not discounted the cash obligations in this table.

(1) Total amounts are included in the November 30, 2011 consolidated balance sheet. See Note 8, Credit Arrangements, to the consolidated financial statements.

(2) Interest payments related to our short-term debt are not included in the table as they do not represent a significant obligation as of November 30, 2011. Also, amounts include the effect of our interest rate swaps based on the LIBOR forward rate at November 30, 2011.

(3) Includes minimum lease payment obligations for non-cancelable equipment and real estate leases in effect as of November 30, 2011.

(4) Approximately 73% of these purchase obligations are for inventory items to be sold in the ordinary course of business. Purchase obligations include all enforceable, legally binding agreements to purchase goods or services that specify all significant terms, regardless of the duration of the agreement. Agreements with variable terms are excluded because we are unable to estimate the minimum amounts. Another significant purchase obligation relates to capital expenditures.

Other Commercial Commitments We maintain stand-by letters of credit to provide support for certain transactions that our insurance providers and suppliers request. At November 30, 2011, we had committed $37.2 million under these arrangements, of which $31.9 million is cash collateralized. All of the commitments expire within one year.

CONTINGENCIES

See Note 14 — Commitments and Contingencies, to the consolidated financial statements.

In the ordinary course of conducting our business, we become involved in litigation, administrative proceedings and government investigations, including litigation, proceedings and investigations relating to environmental matters. We may incur settlements, fines, penalties or judgments arising as a result of these matters. While we are unable to estimate the ultimate dollar amount of exposure or loss in connection with these matters, we make accruals as warranted. Inherent uncertainties exist in these estimates primarily due to evolving remediation technology, changing regulations, possible third-party contributions and the uncertainties involved in litigation. We believe that we have adequately provided for the potential impact of these contingencies in our consolidated financial statements. We also believe that the outcomes will not significantly affect our results of operations, financial position or cash flows.

Sales of Accounts Receivable

Sales of Accounts Receivable [Abstract]

SALES OF ACCOUNTS RECEIVABLE

NOTE 2 — SALES OF ACCOUNTS RECEIVABLE

The Company periodically contributes, and several of its subsidiaries periodically sell without recourse, certain eligible trade accounts receivable to the Company’s wholly-owned consolidated special purpose subsidiary, CMC Receivables, Inc. (“CMCRV”). CMCRV is structured to be a bankruptcy-remote entity and was formed for the sole purpose of buying and selling receivables generated by the Company. Depending on the Company’s level of financing needs, CMCRV will sell the trade accounts receivable in their entirety to a third party financial institution. The third party financial institution will advance up to a maximum of $100 million for all receivables and the remaining portion due to the Company will be deferred until the ultimate collection of the underlying receivables. On December 28, 2011, the Company amended its domestic sales of receivable facility which increased the capacity to $200 million and extended the maturity date to December 26, 2014. The Company accounts for sales to the financial institution as true sales and the cash advances for receivables are removed from the consolidated balance sheets and reflected as cash provided by operating activities. Additionally, the receivables program contains certain cross-default provisions whereby a termination event could occur if the Company defaulted under one of its credit arrangements. The covenants contained in this agreement are consistent with the credit facility fully described in Note 8, Credit Arrangements.

At November 30, 2011 and August 31, 2011, the Company sold $524.9 million and $557.0 million of receivables, respectively, to the third party financial institution, of which $50.0 million was received as advance payments in both periods. The remaining amounts of $474.9 million and $507.0 million, respectively, are the deferred purchase prices. The fair value of the deferred purchase prices at November 30, 2011 and August 31, 2011 were $463.7 million and $494.7 million, respectively, and are included as trade receivables on the consolidated balance sheets. The carrying value of the deferred purchase price approximates fair value due to the short-term nature of the underlying financial assets.

In addition to the domestic sale of accounts receivable program described above, the Company’s international subsidiaries in Europe and Australia periodically sell accounts receivable without recourse. These arrangements constitute true sales, and once the accounts are sold, they are no longer available to satisfy the Company’s creditors in the event of bankruptcy. Uncollected accounts receivable sold under these arrangements and removed from the consolidated balance sheets were $180.0 million and $132.2 million at November 30, 2011 and August 31, 2011, respectively. The Australian program contains financial covenants in which the subsidiary must meet certain coverage and tangible net worth levels, as defined. At November 30, 2011, the Australian subsidiary was not in compliance with these covenants. Commercial Metals Company provided a guarantee of the Australian subsidiary’s performance resulting in the financial covenants being waived at November 30, 2011. The guarantee will cease to be effective when the Australian subsidiary is in compliance with the financial covenants for two consecutive quarters.

During the three months ended November 30, 2011 and 2010, proceeds from the domestic and international sales of receivables were $528.9 million and $285.5 million, respectively, and cash payments to the owners of receivables were $481.1 million and $263.5 million, respectively. The Company is responsible for servicing the receivables for a nominal servicing fee. Discounts on domestic and international sales of accounts receivable were $1.7 million and $1.2 million for the three months ended November 30, 2011 and 2010, respectively. These discounts primarily represented the costs of funds and were included in selling, general and administrative expenses.

Business Segments [Abstract]

BUSINESS SEGMENTS

NOTE 15 — BUSINESS SEGMENTS

The Company’s reportable segments are based on strategic business areas, which offer different products and services. These segments have different lines of management responsibility as each business requires different marketing strategies and management expertise.

The Company structures the business into the following five segments: Americas Recycling, Americas Mills, Americas Fabrication, International Mills and International Marketing and Distribution. The Americas Recycling segment consists of the scrap metal processing and sales operations primarily in Texas, Florida and the southern United States. The Americas Mills segment includes the Company’s domestic steel mills, including the scrap processing facilities that directly support these mills, and the copper tube minimill. The copper tube minimill is aggregated with the Company’s steel mills because it has similar economic characteristics. The Americas Fabrication segment consists of the Company’s rebar fabrication operations, fence post manufacturing plants and construction-related and other products facilities. The International Mills segment includes the minimill and recycling operations in Poland and fabrication operations in Europe, which have been presented as a separate segment because the economic characteristics of their markets and the regulatory environment in which they operate differ from the Company’s domestic mills and rebar fabrication operations. International Marketing and Distribution includes international operations for the sales, distribution and processing of steel products, ferrous and nonferrous metals and other industrial products. Additionally, the International Marketing and Distribution segment includes the Company’s U.S.-based trading and distribution divisions, CMC Cometals and CMC Cometals Steel. The international distribution operations consist only of physical transactions and not positions taken for speculation. Corporate contains expenses of the Company’s corporate headquarters and interest expense relating to its long-term public debt and commercial paper program.

The financial information presented for the International Mills segment excludes the minimill in Croatia and the financial information presented for the Americas Fabrication segment excludes its joist and deck fabrication operations. These operations have been classified as discontinued operations in the consolidated statements of earnings. See Note 7, Discontinued Operations, for more detailed information.

The Company uses adjusted operating profit (loss) to measure segment performance. Intersegment sales are generally priced at prevailing market prices. Certain corporate administrative expenses are allocated to segments based upon the nature of the expense.

NOTE 10 — FAIR VALUE

The Company has established a fair value hierarchy which prioritizes the inputs to valuation techniques used to measure fair value into three levels. These levels are determined based on the lowest level input that is significant to the fair value measurement.

The following table summarizes information regarding the Company’s financial assets and financial liabilities that were measured at fair value on a recurring basis:

Though under no obligation to fund this plan, the Company has segregated assets in a trust. The plan assets and liabilities consist of securities included in various mutual funds.

The Company’s long-term debt is predominantly publicly held. The fair value was approximately $1.13 billion at November 30, 2011 and $1.24 billion at August 31, 2011. Fair value was determined by indicated market values.

Income Taxes [Abstract]

INCOME TAXES

NOTE 11 — INCOME TAXES

The Company’s effective income tax rate for continuing operations for the three months ended November 30, 2011 and 2010 was (320.7)% and 31.1%, respectively. The effective tax rate from discontinued operations for the three months ended November 30, 2011 and 2010 was 35.9% and (1.9)%, respectively.

During the three months ended November 30, 2011, the Company recognized a tax loss in the amount of $291 million related to its investments in its Croatian company. As a result, a tax benefit of $102 million was recorded from these losses in the first quarter of 2012 in continuing operations which is the primary reason for the variance in the tax rate from continuing operations in first quarter of 2011. The Company will report and disclose the losses on these investments on its U.S. tax return as ordinary worthless stock and bad debt deductions.

The Company made net payments of $12.5 million and had net refunds of $1.9 million for income taxes during the three months ended November 30, 2011 and 2010, respectively.

The reserve for unrecognized tax benefits relating to the accounting for uncertainty in income taxes was $10.0 million and $20.4 million, exclusive of interest and penalties, as of November 30, 2011 and 2010, respectively.

The Company’s policy classifies interest recognized on an underpayment of income taxes and any statutory penalties recognized on a tax position as tax expense and the balances at the end of a reporting period are recorded as part of the current or noncurrent reserve for uncertain income tax positions. For the three months ended November 30, 2011, before any tax benefits, the Company recorded immaterial amounts of accrued interest and penalties on unrecognized tax benefits.

During the next twelve months, it is reasonably possible that the statute of limitations may lapse pertaining to positions taken by the Company in prior year tax returns or that income tax audits in various taxing jurisdictions could be finalized. As a result, the total amount of unrecognized tax benefits may decrease, which would reduce the provision for taxes on earnings by an immaterial amount.

The following is a summary of tax years subject to examination:

U.S. Federal - 2009 and forward

U.S. States - 2006 and forward

Foreign - 2005 and forward

The Company is currently under examination by the Internal Revenue Service and several U.S. states. We believe our recorded tax liabilities as of November 30, 2011 sufficiently reflect the anticipated outcome of these examinations.

Share-Based Compensation [Abstract]

SHARE-BASED COMPENSATION

NOTE 12 — SHARE-BASED COMPENSATION

The Company recognizes share-based compensation at fair value in the financial statements. The fair value of each share-based award is estimated at the date of grant using either the Black-Scholes pricing model or a binomial model. Total compensation cost is amortized over the requisite service period using the accelerated method of amortization for grants with graded vesting or using the straight-line method for grants with cliff vesting. The Company recognized share-based compensation of $3.9 million and $2.1 million for the three months ended November 30, 2011 and 2010, respectively, as a component of selling, general and administrative expenses. At November 30, 2011, the Company had $38.3 million of total unrecognized pre-tax compensation cost related to non-vested share-based compensation arrangements. This cost is expected to be recognized over three years.

Combined information for shares subject to options and stock appreciation rights (“SARs”), excluding the cash component, for the three months ended November 30, 2011 was as follows:

	Number			Weighted Average Exercise Price		Weighted Average Remaining Contractual Life (Years)
Outstanding at September 1, 2011		2,807,498		$	27.45

Forfeited		(24,301	)		12.49
Outstanding at November 30, 2011		2,773,943		$	12.96

During the first quarter of 2012, the Compensation Committee (the “Committee”) of the Board of Directors approved a grant of restricted stock units (“RSUs”), SARs and PSUs to employees. The PSUs will vest upon the achievement of certain target levels of the performance goals and objectives of the Company over the performance period of approximately three years. The actual number of PSUs granted will be based on the level of achievement. Upon achievement of any of the performance goals, the awards will be paid out in cash. Additionally, a portion of the RSUs and SARs are settled in cash. The Company accounts for the cash component of stock awards as a liability award and the liability is adjusted at each reporting period based on the share price of Company’s common stock.

CREDIT ARRANGEMENTS

NOTE 8 — CREDIT ARRANGEMENTS

The Company’s revolving credit facility of $400 million has a maturity date of November 24, 2012. On December 27, 2011, the Company entered into a third amended and restated credit agreement which reduced the revolving credit facility to $300 million and extended the maturity date to December 27, 2016. The maximum facility can be increased to $400 million with the consent of all parties. Under the current credit facility, the Company is required to maintain a minimum interest coverage ratio of not less than 2.50 to 1.00 for the twelve month cumulative period ended November 30, 2011 and for each fiscal quarter on a rolling twelve month cumulative period thereafter. At November 30, 2011, the Company’s interest coverage ratio was 3.27 to 1.00. The agreement also requires the Company to maintain a debt to capitalization ratio covenant not greater than 0.60 to 1.00. At November 30, 2011, the Company’s debt to capitalization ratio was 0.53 to 1.00. The agreement provides for interest based on LIBOR, Eurodollar or Bank of America’s prime rate. The Company did not have any amounts outstanding on the revolving credit facility at November 30, 2011 or August 31, 2011.

The Company has numerous uncommitted credit facilities available from domestic and international banks. These credit facilities are used, in general, to support import letters of credit (including accounts payable settled under bankers’ acceptances), foreign exchange transactions and short-term advances which are priced at market rates.

Long-term debt, including the net effect of interest rate swap revaluation adjustments, was as follows:

(in thousands)	Weighted Average Interest Rate at November 30, 2011			November 30, 2011		August 31, 2011
5.625% notes due November 2013		3.8	%	$	206,177	$	207,752

Less current maturities					3,697		58,908
				$	1,152,869	$	1,167,497

Interest on the notes is payable semiannually.

During the third quarter of 2011, the Company entered into an interest rate swap transaction to hedge the fair value changes on its 6.50% notes due July 2017 (“2017 Notes”). During the third quarter of 2010, the Company entered into interest rate swap transactions on its 5.625% notes due November 2013 (“2013 Notes”) and 7.35% notes due August 2018 (“2018 Notes”). The swap transactions were designated as fair value hedges at inception and effectively convert all fixed-rate interest to floating rate interest on the Company’s 2013 Notes, and effectively convert fixed-rate interest to floating rate interest with respect to $300 million in principal amount on each of the 2017 Notes and the 2018 Notes and have termination dates of November 15, 2013, July 15, 2017 and August 15, 2018, respectively. Under the terms of the swaps, the Company pays the floating LIBOR plus 303 basis points with respect to the 2013 Notes, LIBOR plus 374 basis points with respect to the 2017 Notes and LIBOR plus 367 basis points with respect to the 2018 Notes and receives payments identical to the hedged item fixed rates.

The CMCS financing agreement was used for capital expenditures and other uses. The note has scheduled principal and interest payments in semiannual installments. During the first quarter of 2012, the Company presented CMCS as a discontinued operation. As a result, the CMCS financing agreement was classified as held for sale and included in accrued expenses and other payables on the consolidated balance sheet. The outstanding balance at November 30, 2011 was $17.3 million. See Note 7, Discontinued Operations, for additional information.

The CMC Zawiercie (“CMCZ”) term note was repaid on October 20, 2011. Subsequently, CMCZ entered into current uncommitted credit facilities of $76.0 million with several banks, which expire in the first quarter of 2013. At November 30, 2011, $42.3 million was outstanding under these facilities and included in notes payable on the consolidated balance sheets. The weighted average interest rate on these facilities was approximately 5.5% at November 30, 2011.

Interest of $0.4 million and $0.2 million was capitalized in the cost of property, plant and equipment constructed for the three months ended November 30, 2011 and 2010, respectively. Interest of $4.4 million and $5.0 million was paid for the three months ended November 30, 2011 and 2010, respectively.

DISCONTINUED OPERATIONS

NOTE 7 — DISCONTINUED OPERATIONS

During the first quarter of 2012, the Company announced its decision to exit its steel pipe manufacturing operations in Croatia (“CMCS”) by closure of the facility and sale of the assets. The Company has begun winding down operations and expects the backlog and liquidation of inventory to be completed in the second quarter of 2012. The Company determined that the decision to exit this business met the definition of a discontinued operation. As a result, this business has been presented as a discontinued operation for all periods. During the first quarter of 2012, the Company recorded severance costs of approximately $18 million associated with exiting the business. This business was in the International Mills segment.

During the second quarter of 2010, the Company’s Board approved a plan to exit the joist and deck business through the sale of those facilities. The Company determined that the decision to exit this business met the definition of a discontinued operation. As a result, this business has been presented as a discontinued operation for all periods. At November 30, 2011, the remaining assets consist of real property for three locations. The joist and deck business was in the Americas Fabrication segment.

As of November 30, 2011, the assets and liabilities of discontinued operations have been presented as held for sale and included in other current assets and accrued expenses and other payables on the consolidated balance sheets. Financial information for discontinued operations was as follows:

Derivatives and Risk Management [Abstract]

DERIVATIVES AND RISK MANAGEMENT

NOTE 9 — DERIVATIVES AND RISK MANAGEMENT

The Company’s worldwide operations and product lines expose it to risks from fluctuations in metals commodity prices, foreign currency exchange rates, natural gas prices and interest rates. One objective of the Company’s risk management program is to mitigate these risks using derivative instruments. The Company enters into metal commodity futures and forward contracts to mitigate the risk of unanticipated declines in gross margin due to the volatility of the commodities’ prices, enters into foreign currency forward contracts which match the expected settlements for purchases and sales denominated in foreign currencies and enters into natural gas forward contracts to mitigate the risk of unanticipated changes in operating cost due to the volatility of natural gas prices. When sales commitments to customers include a fixed price freight component, the Company occasionally enters into freight forward contracts to minimize the effect of the volatility of ocean freight rates. The Company enters into interest rate swap contracts to maintain a portion of the Company’s debt obligations at variable interest rates. These interest rate swap contracts, under which the Company has agreed to pay variable rates of interest and receive fixed rates of interest, are designated as fair value hedges of fixed-rate debt.

At November 30, 2011, the Company’s notional value of its foreign currency contract commitments was $298 million and interest rate swap contract commitments was $800 million.

The following table provides commodity contract commitments as of November 30, 2011:

Commodity	Long/Short	Total
Aluminum	Long		5,175 MT
Aluminum	Short		3,225 MT
Copper	Long		848 MT
Copper	Short		5,636 MT
Zinc	Long		36 MT
Natural Gas	Long		160,000 MMBtu

• MT = Metric Ton

• MMBtu = One million British thermal units

The Company designates only those contracts which closely match the terms of the underlying transaction as hedges for accounting purposes. These hedges resulted in substantially no ineffectiveness in the statements of earnings, and there were no components excluded from the assessment of hedge effectiveness for the three months ended November 30, 2011 and 2010. Certain of the foreign currency and commodity contracts were not designated as hedges for accounting purposes, although management believes they are essential economic hedges.

The following tables summarize activities related to the Company’s derivative instruments and hedged (underlying) items recognized within the statements of earnings (in thousands):

Derivatives Not Designated as Hedging Instruments	Location	Three Months Ended November 30,
		2011			2010
Commodity	Cost of goods sold	$	3,577		$	(10,286	)
Foreign exchange	Net sales		(108	)		(18	)
Foreign exchange	Cost of goods sold		(233	)		580
Foreign exchange	SG&A expenses		(7,159	)		(3,324	)
Loss before taxes		$	(3,923	)	$	(13,048	)

The Company’s fair value hedges are designated for accounting purposes with gains and losses on the hedged (underlying) items offsetting the gain or loss on the related derivative transaction. Hedged (underlying) items relate to firm commitments on commercial sales and purchases, capital expenditures and fixed-rate debt obligations. As of November 30, 2011, fair value hedge accounting for interest rate swap contracts increased the carrying value of debt instruments by $45.6 million.

Interest rate	Interest expense		(1,205	)		(21,555	)
Loss before taxes		$	(3,784	)	$	(13,669	)

The Company recognizes the impact of actual and estimated net periodic settlements of current interest on active interest rate swaps as adjustments to interest expense. The Company recorded reductions to interest expense related to interest rate swaps of $4.2 million and $3.3 million for the three months ended November 30, 2011 and 2010, respectively. These amounts represent the net of the Company’s periodic variable-rate interest obligations and the swap counterparty’s fixed-rate interest obligations. The Company’s variable-rate obligations are based on a spread from the six-month LIBOR.

Stockholders' Equity and Earnings (Loss) Per Share Attributable to CMC [Abstract]

STOCKHOLDERS' EQUITY AND EARNINGS (LOSS) PER SHARE ATTRIBUTABLE TO CMC

NOTE 13 — STOCKHOLDERS’ EQUITY AND EARNINGS PER SHARE ATTRIBUTABLE TO CMC

In calculating earnings per share, there were no adjustments to net earnings to arrive at earnings for any periods presented. The reconciliation of the denominators of the earnings per share calculations was as follows:

	Three Months Ended November 30,
	2011		2010
Shares outstanding for basic earnings per share		115,530,545		114,319,017
Effect of dilutive securities:
Stock based incentive/purchase plans		918,938		904,676
Shares outstanding for diluted earnings per share		116,449,483		115,223,693

For the three months ended November 30, 2011 and 2010, SARs with total share commitments of 2.7 million and 2.3 million, respectively, were antidilutive and therefore excluded from the calculation of diluted earnings per share. All stock options and SARs expire by 2018.

The Company’s restricted stock is included in the number of shares of common stock issued and outstanding, but omitted from the basic earnings (loss) per share calculation until the shares vest.

The Company did not purchase any shares during the first quarter of 2012 and had remaining authorization to purchase 8,259,647 shares of its common stock at November 30, 2011.
