QUANEX BUILDING PRODUCTS CORPORATION

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1. Description of Business and Basis of Presentation

Quanex Building Products Corporation and its subsidiaries (Quanex or the Company) are managed on a decentralized basis and operate in two business segments: Engineered Products and Aluminum Sheet Products. The Engineered Products segment produces engineered systems, products and components primarily serving the window and door industry, while the Aluminum Sheet Products segment produces mill finished and coated aluminum sheet serving the broader building products markets and secondary markets such as capital goods and transportation. The primary market drivers are residential housing starts and residential remodeling expenditures. Quanex believes it is a technological leader in the production of aluminum sheet products, flexible insulating glass spacer systems, extruded vinyl profiles, thin film solar panel sealants, and precision-formed metal and wood products which primarily serve the North American building products markets. The Company uses low-cost production processes, and engineering and metallurgical expertise to provide customers with specialized products for specific applications.

On December 12, 2007, Quanex Building Products Corporation was incorporated in the state of Delaware as a subsidiary of Quanex Corporation to facilitate the separation of Quanex Corporation’s vehicular products and building products businesses. The separation occurred on April 23, 2008 through the spin-off of Quanex Corporation’s building products business to its shareholders immediately followed by the merger of Quanex Corporation (consisting principally of the vehicular products business and all non-building products related corporate accounts) with a wholly-owned subsidiary of Gerdau S.A. (Gerdau). This is hereafter referred to as the “Separation”. In March 2011, the Company acquired Edgetech I.G., Inc. and its German subsidiary. Headquartered in Cambridge, Ohio, Edgetech has three manufacturing facilities (U.S., U.K. and Germany) that produce and market a full line of insulating glass spacer systems for window and door customers in North America and abroad. In November 2011, management committed to a plan to consolidate its Truseal and U.S. Edgetech facilities. In 2010, management closed its start-up facility in China, and accordingly, the China assets and liabilities, results of operations and cash flows are reported as discontinued operations for all periods presented. Unless otherwise noted, all disclosures in the notes accompanying the consolidated financial statements reflect only continuing operations.

The interim unaudited consolidated financial statements of the Company include all adjustments which, in the opinion of management, are necessary for a fair presentation of the Company’s financial position and results of operations. All such adjustments are of a normal recurring nature. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. The preparation of these financial statements requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying footnotes. Estimates and assumptions about future events and their effects cannot be perceived with certainty. Estimates may change as new events occur, as more experience is acquired, as additional information becomes available and as the Company’s operating environment changes. Actual results could differ from estimates. These statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended October 31, 2011.

2. New Accounting Pronouncements

In December 2010, the FASB issued Accounting Standards Update No. 2010-28 (ASU 2010-28) Intangibles—Goodwill and Other (ASC Topic 350) — When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts which amended ASC Topic 350 “Goodwill and Other.” ASU 2010-28 requires an entity with reporting units that have carrying amounts that are zero or negative to assess whether it is more likely than not that the reporting units’ goodwill is impaired. If the entity determines that it is more likely than not that the goodwill of one or more of its reporting units is impaired, the entity is required to perform Step 2 of the goodwill impairment test for those reporting unit(s) and record any resulting impairment as a cumulative-effect adjustment to beginning retained earnings. The provisions of ASU 2010-28 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2010. Early adoption is not permitted. The Company adopted this standard on November 1, 2011. The adoption of ASU 2010-28 did not have a material impact on the Company’s consolidated financial statements.

QUANEX BUILDING PRODUCTS CORPORATION

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (continued)

In May 2011, the FASB issued Accounting Standards Update No. 2011-04 (ASU 2011-04), Fair Value Measurement (ASC Topic 820) Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs. The amended guidance changes the wording used to describe many requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements. Additionally, the amendments clarify the FASB’s intent about the application of existing fair value measurement requirements. The guidance provided in ASU 2011-04 is effective for interim and annual periods beginning after December 15, 2011 (February 1, 2012 for the Company) and is applied prospectively. The Company does not expect the provisions of ASU 2011-04 to have a material effect on its consolidated financial statements.

In June 2011, the FASB issued Accounting Standards Update No. 2011-05 (ASU 2011-05), Presentation of Comprehensive Income. This amendment will require companies to present the components of net income and other comprehensive income either as one continuous statement or as two consecutive statements. It eliminates the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity. The amended guidance, which must be applied retroactively, is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 (November 1, 2012 for the Company), with earlier adoption permitted. ASU 2011-05 impacts presentation only and will have no effect on the Company’s financial condition, results of operations or cash flows. In December 2011, the FASB issued Accounting Standards Update No. 2011-12 (ASU 2011-12), “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05.” ASU 2011-12 deferred the effective date of ASU 2011-05 related to the presentation of reclassifications of items out of accumulated other comprehensive income. All other requirements of ASU 2011-05 were not affected by ASU 2011-12.

In September 2011, the FASB issued Accounting Standards Update No. 2011-08 (ASU 2011-08), Testing Goodwill for Impairment which amends the guidance in ASC 350-20. The amendments in ASU 2011-08 provide entities with the option of performing a qualitative assessment before performing the first step of the two-step impairment test. If entities determine, on the basis of qualitative factors, it is not more likely than not that the fair value of the reporting unit is less than the carrying amount, then performing the two-step impairment test would be unnecessary. However, if an entity concludes otherwise, then it is required to perform the first step of the two-step impairment test by calculating the fair value of the reporting unit and comparing the fair value with the carrying amount of the reporting unit. If the carrying amount of a reporting unit exceeds its fair value, then the entity is required to perform the second step of the goodwill impairment test to measure the amount of the impairment loss, if any. ASU 2011-08 also provides entities with the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to the first step of the two-step impairment test. ASU 2011-08 is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, (November 1, 2012 for the Company), although early adoption is permitted. The provisions of ASU 2011-08 will not have a material effect on its consolidated financial statements.

In December 2011, the FASB issued Accounting Standards Update No. 2011-11 (ASU 2011-11), Disclosures about Offsetting Assets and Liabilities where entities are required to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. This scope would include derivatives, sale and repurchase agreements, and reverse sale and repurchase agreements, and securities borrowing and securities lending arrangements. These disclosures assist users of financial statements in evaluating the effect or potential effect of netting arrangements on a company’s financial position. The Company is required to apply the amendments for annual reporting periods beginning on or after January 1, 2013 (November 1, 2013 for the Company). The Company does not expect the provisions of ASU 2011-11 to have a material impact on its consolidated financial statements.

3. Acquisitions

On March 31, 2011, Quanex completed its acquisition of Edgetech I.G., Inc., an Ohio corporation (“Edgetech I.G.”), the United Kingdom division of Edgetech (“Edgetech UK”), and Edgetech Europe GmbH, a German company (“Edgetech Germany” and together with Edgetech I.G. and Edgetech UK, “Edgetech”). Headquartered in Cambridge, Ohio, Edgetech has three manufacturing facilities located in the United States, the United Kingdom and Germany that produce a full line of warm-edge, dual seal insulating glass spacer systems for window and door customers in North America and abroad. Edgetech’s products separate and seal double and triple glass within a window and act as a thermal barrier that enhances the window’s energy efficiency. Edgetech has been integrated into the Engineered Products segment.

QUANEX BUILDING PRODUCTS CORPORATION

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (continued)

As consideration for the acquisition, Quanex paid $104.4 million in cash, net of $0.8 million of cash acquired. Of the cash paid, $7.0 million was placed into an escrow fund to satisfy certain indemnity obligations under the merger agreement. Additionally, Quanex is responsible for the tax liability resulting from the pre-closing reorganization of Lauren and its subsidiaries limited to $3.5 million, of which $3.0 million has been paid. The Edgetech acquisition was accounted for as a business combination using the acquisition method of accounting under which the total purchase price consideration is allocated to assets and liabilities assumed based upon their fair values. The purchase price allocation resulted in goodwill of $44.6 million, which is not deductible for income tax purposes. Any transaction-related costs in connection with the Edgetech acquisition were expensed as occurred within Selling, general and administrative expense in its Consolidated Statement of Income.

The following table provides consolidated results of operations for the three months ended January 31, 2012 compared to unaudited pro forma consolidated results of operations for the combined entity for the three months ended January 31, 2011 as if Edgetech had been acquired as of November 1, 2009.

		September 30,			September 30,
	Three Months Ended January 31,
	Actual			Pro forma
	2012			2011
	(In thousands, except per share amounts)
Net sales	$	161,579		$	177,335
Operating income (loss)		(11,304	)		(6,842	)
Income (loss) from continuing operations	$	(6,748	)	$	(4,387	)
Diluted earnings (loss) per common share from continuing operations	$	(0.18	)	$	(0.12	)

The unaudited pro forma consolidated results of operations were prepared using the acquisition method of accounting and are based on the historical financial information of the Company and Edgetech. The unaudited pro forma financial information does not purport to reflect the results the combined company may achieve in future periods or the results that would have been obtained had Quanex acquired Edgetech on the first day of its fiscal 2010 period. The unaudited pro forma financial information does not include any operating efficiencies or cost savings that may be achieved or any integration expenses. Additionally, the historical Edgetech financial information has not been adjusted to remove expenses that will cease under Quanex’s ownership, such as the prior parent company allocation, or to add incremental anticipated stand-alone expenses going forward. Generally, the pro forma financial information reflects the allocation of the purchase price to the appropriate assets and liabilities based upon their fair values, and related changes in depreciation and amortization expense. Accordingly, such amounts are not necessarily indicative of the results that would have occurred if the acquisition had occurred on the dates indicated or that may result in the future. The unaudited pro forma information reflects primarily the following unaudited pro forma adjustments for the three months ended January 31, 2011:

• Historical pre-acquisition results of operations for Edgetech for the three months ended January 31, 2011;

• Amortization expense related to the fair value of identifiable intangible assets acquired;

• Additional depreciation expense related to the fair value adjustment to property, plant and equipment acquired;

• Additional facility rental expense;

• Reduction of expense of $1.1 million in the three months ended January 31, 2011 to remove the transaction-related costs incurred;

• The Edgetech historical results and all of the above adjustments were adjusted for the applicable tax impact.

		September 30,		September 30,
	January 31,		October 31,
	2012		2011
	(In thousands)
LIFO	$	21,215	$	18,782
FIFO		42,935		37,060
Total	$	64,150	$	55,842

An actual valuation of inventory under the last in, first out (LIFO) method can be made only at the end of each year based on the inventory costs and levels at that time. Accordingly, interim LIFO calculations must be based on management’s estimates of expected year-end inventory costs and levels. Because these are subject to many factors beyond management’s control, interim results are subject to the final year-end LIFO inventory valuation which could significantly differ from interim estimates. To estimate the effect of LIFO on interim periods, the Company performs a projection of the year-end LIFO reserve and considers expected year-end inventory pricing and expected inventory levels. Depending on this projection, the Company may record an interim allocation of the projected year-end LIFO calculation. This projection resulted in zero interim LIFO allocation (reported in Cost of sales) for the three months ended January 31, 2012. With respect to inventories valued using the LIFO method, replacement cost exceeded the LIFO value by approximately $12.3 million as of January 31, 2012 and October 31, 2011, respectively.

6. Earnings and Dividends Per Share

Earnings Per Share

Fiscal 2012 and 2011 basic and diluted earnings per share from continuing operations are identical as the Company reported a loss from continuing operations. The computation of diluted earnings per share excludes outstanding options and other common stock equivalents in periods where inclusion of such potential common stock instruments would be anti-dilutive in the periods presented. When income from continuing operations is a loss, all potential dilutive instruments are excluded from the computation of diluted earnings per share as they would be anti-dilutive. Accordingly, for the three months ended January 31, 2012, 0.1 million of restricted stock and 0.3 million of common stock equivalents were excluded from the computation of diluted earnings per share as the Company had a loss from continuing operations. Accordingly, for the three months ended January 31, 2011, 0.2 million of restricted stock and 0.4 million of common stock equivalents were excluded from the computation of diluted earnings per share as the Company had a loss from continuing operations.

For the three months ended January 31, 2012 and 2011, the Company had 1.3 million and 0.5 million, respectively, of securities that are potentially dilutive in future earnings per share calculations. Such dilution will be dependent on the excess of the market price of the Company’s stock over the exercise price and other components of the treasury stock method.

Dividends Per Share

During the three months ended January 31, 2012 and 2011, the Company paid $0.04 cash dividend per common share.

7. Comprehensive Income

Comprehensive income comprises net income and all other non-owner changes in equity, including foreign currency translation, pension related adjustments and realized and unrealized gains and losses on derivatives, if any. Comprehensive income for the three months ended January 31, 2012 and 2011 was as follows:

		September 30,			September 30,
	Three Months Ended

Foreign currency translation adjustment		(1,834	)		92
Other		—			2
Total comprehensive income (loss), net of taxes	$	(8,582	)	$	(4,646	)

The 2012 foreign currency translation activity is primarily associated with Edgetech, acquired by the Company on March 31, 2011. As a result of this acquisition, Quanex has operations in Germany and the United Kingdom whose functional currency is the Euro and the British Pound Sterling, respectively.

Long-term debt	$	1,294	$	1,314

The Company’s $270.0 million Senior Unsecured Revolving Credit Facility (the Credit Facility) was executed on April 23, 2008. The Credit Facility has a five-year term and is unsecured. The Credit Facility expires April 23, 2013 and provides for up to $50.0 million for standby letters of credit, limited to the undrawn amount available under the Credit Facility. Borrowings under the Credit Facility bear interest at a spread above LIBOR based on a combined leverage and ratings grid. Proceeds from the Credit Facility may be used to provide availability for acquisitions, working capital, capital expenditures and general corporate purposes.

Under the Credit Facility, the Company is obligated to comply with certain financial covenants requiring the Company to maintain a Consolidated Leverage Ratio of no more than 3.25 to 1 and a Consolidated Interest Coverage Ratio of no less than 3.00 to 1. As defined by the Credit Facility’s indenture, the Consolidated Leverage Ratio is the ratio of consolidated indebtedness as of such date to consolidated EBITDA for the previous four fiscal quarters; and the Consolidated Interest Coverage Ratio is the ratio of consolidated EBITDA to consolidated interest expense for the previous four consecutive fiscal quarters. EBITDA is defined by the indenture to include proforma EBITDA of acquisitions and to exclude certain items like non-cash charges. Additionally, the Credit Facility contains certain limitations on additional indebtedness, asset or equity sales, and acquisitions. Dividends and other distributions are permitted so long as after giving effect to such dividend or stock repurchase, there is no event of default.

As of January 31, 2012, the Company had no borrowings under the Credit Facility, and the Company was in compliance with all Credit Facility financial covenants. The availability under the Credit Facility is a function of both the facility amount utilized and meeting covenant requirements. Although there were no borrowings on the Credit Facility and only $5.6 million of outstanding letters of credit under the Credit Facility, the aggregate availability under the Credit Facility was limited by the Consolidated Leverage Ratio resulting in an availability of $173.1 million at January 31, 2012.

9. Retirement Plans

The Company has a number of retirement plans covering substantially all employees. The Company provides both defined benefit and defined contribution plans. In general, the plant or location of employment determines an employee’s coverage for retirement benefits. Effective with the respective acquisition dates in the second fiscal quarter of 2011, the Edgetech employees were eligible to participate in the Company’s retirement plans.

Pension Plan

The Company has a non-contributory, single employer defined benefit pension plan that covers substantially all non-union employees. Effective January 1, 2007, the Company amended this defined benefit pension plan to include a new cash balance formula for all new salaried employees hired on or after January 1, 2007 and for any non-union employees who were not participating in a defined benefit plan prior to January 1, 2007. All

11

QUANEX BUILDING PRODUCTS CORPORATION

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (continued)

new salaried employees are eligible to receive credits equivalent to 4% of their annual eligible wages, while some of the employees at the time of the plan amendment were “grandfathered” and are eligible to receive credits ranging up to 6.5% based upon a percentage they received in the defined contribution plan prior to the amendment of the pension plan. Additionally, every year the participants will receive an interest related credit on their respective balance equivalent to the prevailing 30-year Treasury rate. Benefits for participants in this plan prior to January 1, 2007 continue to be based on a more traditional formula for retirement benefits, where the plan pays benefits to employees upon retirement using a formula based upon years of service and pensionable compensation prior to retirement. Of the Company’s participants, 99% are under the cash balance formula.

The components of net periodic pension cost are as follows:

		September 30,			September 30,
	Three Months Ended January 31,
	2012			2011
	(In thousands)
Net periodic benefit cost:
Service cost	$	980		$	937
Interest cost		204			200
Expected return on plan assets		(277	)		(258	)
Amortization of net loss		50			22
Net periodic benefit cost	$	957		$	901

The increase in net pension cost from 2011 to 2012 is primarily attributable to an increase in participants from the Edgetech acquisition. The Company’s pension funding policy generally has been to make the minimum annual contributions required by applicable regulations while considering targeted funded percentages. In fiscal 2010, the Company decided to modify its funding strategy and accelerate contributions to target a 100% funding threshold. Additionally, the Company will consider funding fiscal year requirements early in the fiscal year to potentially maximize returns on assets. The Company made no contributions to its defined benefit plan during the three months ended January 31, 2012. In February 2012, the Company contributed $4.2 million to the plan. Future contributions are dependent on many variables, including the variability of the market value of the assets as compared to the obligation and other market or regulatory conditions. In addition, the Company takes into consideration its business investment opportunities and resulting cash requirements. Accordingly, actual funding may differ greatly from current estimates.

10. Industry Segment Information

Quanex has two reportable segments: Engineered Products and Aluminum Sheet Products. The Engineered Products segment produces systems, finished products and components serving the OEM residential window and door industry, while the Aluminum Sheet Products segment produces mill finished and coated aluminum sheet serving the broader building and construction markets. The primary market drivers of both segments are residential repair and remodel activity (R&R) and new home construction.

The Company measures its inventory at the segment level on a FIFO or weighted-average basis; however at the consolidated Company level, approximately one third of the inventory is measured on a LIFO basis. The LIFO reserve is computed on a consolidated basis as a single pool and is thus treated as a corporate expense. See Note 5 to the financial statements for more information. LIFO inventory adjustments along with corporate office charges and intersegment eliminations are reported as Corporate, Intersegment Eliminations or Other. The Company accounts for intersegment sales and transfers as though the sales or transfers were to third parties, that is, at current market prices. Intersegment sales, related cost of sales, and intercompany profit are eliminated in consolidation at Corporate. Corporate assets primarily include cash and equivalents partially offset by the Company’s consolidated LIFO inventory reserve.

11. Stock-Based Compensation

Effective with the Separation on April 23, 2008, the Company established the Quanex Building Products Corporation 2008 Omnibus Incentive Plan (the 2008 Plan). The 2008 Plan provides for the granting of stock options, stock appreciation rights, restricted stock awards, restricted stock units (RSUs), performance stock awards, performance unit awards, annual incentive awards, other stock-based awards and cash-based awards. The 2008 Plan is administered by the Compensation and Management Development Committee of the Board of Directors and allows for immediate, graded or cliff vesting options, but options must be exercised no later than ten years from the date of grant. The aggregate number of shares of common stock originally authorized for grant under the 2008 Plan was 2,900,000. At the Company’s annual shareholder meeting in February 2011, the shareholders approved an amendment which increased the aggregate number of shares available for grant under the 2008 Plan by an additional 2,400,000 shares. Any officer, key employee and/or non-employee director of the Company or any of its affiliates is eligible for awards under the 2008 Plan. The initial awards granted under the 2008 Plan were on April 23, 2008; service is the vesting condition.

13

QUANEX BUILDING PRODUCTS CORPORATION

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (continued)

The Company’s practice is to grant options and restricted stock or RSUs to non-employee directors on October 31st of each year, with an additional grant of options to each director on the date of his or her first anniversary of service. Additionally, the Company’s practice is to grant options, restricted stock and RSUs to employees at the Company’s December board meeting and occasionally to key employees as deemed appropriate at other times during the year. The exercise price of the option awards is equal to the closing market price on the date granted. The Company generally issues shares from treasury stock, if available, to satisfy stock option exercises and grants of restricted stock. If there are no shares in treasury stock, the Company issues additional shares of common stock. The Company has not capitalized any stock-based compensation cost as part of inventory or fixed assets during the three months ended January 31, 2012 and 2011.

Restricted Stock Awards

Under the 2008 Plan, common stock may be awarded to key employees, officers and non-employee directors. The recipient is entitled to all of the rights of a shareholder, except that during the forfeiture period the shares are nontransferable. The awards vest over a specified time period, but typically either immediately vest or cliff vest over a three-year period with service as the vesting condition. Upon issuance of stock under the plan, fair value is measured by the grant-date price of the Company’s shares. This fair value is then expensed over the restricted period with a corresponding increase to additional paid-in-capital. A summary of non-vested restricted stock award changes during the three months ended January 31, 2012 follows:

		September 30,			September 30,
	Shares			Weighted - Average Grant-Date Fair Value Per Share
Non-vested at October 31, 2011		256,390		$	12.67
Granted		83,900			15.08
Vested		(115,790	)		7.82
Non-vested at January 31, 2012		224,500		$	16.08

The weighted-average grant-date fair value of restricted stock granted during the three months ended January 31, 2012 and 2011 was $15.08 and $16.90 per share, respectively. The total fair value of restricted stock vested during the three months ended January 31, 2012 was $0.9 million. There were no restricted stock shares that vested during the three months ended January 31, 2011. Total unrecognized compensation cost related to unamortized restricted stock awards was $2.2 million as of January 31, 2012. This cost is expected to be recognized over a weighted-average period of 2.2 years.

Stock Options

As described in the Company’s Annual Report on Form 10-K for the fiscal year ended October 31, 2011, the Company uses the Black-Scholes-Merton option-pricing model to estimate the fair value of its stock options. The fair value of each option was estimated on the date of grant. The following is a summary of valuation assumptions and resulting grant-date fair values for grants during the following periods:

		September 30,			September 30,
	Three Months Ended January 31,
	2012			2011
Weighted-average expected volatility		54.0	%		53.0	%
Expected term (in years)		4.9-5.1			4.9-5.1
Risk-free interest rate		1.0	%		1.6	%

Below is a table summarizing the stock option shares activity for the 2008 Plan since October 31, 2011:

		September 30,			September 30,		September 30,		September 30,
	Shares			Weighted- Average Exercise Price Per Share		Weighted- Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value (000s)

Exercisable at January 31, 2012		1,726,394		$	13.33		6.6	$	5,482

The total intrinsic value of options (the amount by which the market price of the stock on the date of exercise exceeded the exercise price of the option) exercised during the three months ended January 31, 2012 and 2011 was $12 thousand and $0.2 million, respectively. The total fair value of shares vested during the three months ended January 31, 2012 and 2011 was $2.1 million and $1.3 million, respectively. Total unrecognized compensation cost related to stock options granted under the 2008 Plan was $4.6 million as of January 31, 2012. This cost is expected to be recognized over a weighted-average period of 1.9 years.

Restricted Stock Units

RSUs vest over a specified time period, but typically either immediately vest or cliff vest over a three-year period with service as the vesting condition. RSUs are not considered to be outstanding shares of common stock and do not have voting rights. Holders of RSUs receive cash for an equivalent amount of cash dividends paid on the underlying common stock. Upon the earlier of the date the director ceases to be a board member or a change of control or upon vesting for the employee grants, each RSU is payable in cash in an amount equal to the market value of one share of the Company’s common stock. Accordingly, the RSU liability will be adjusted to fair market value at each reporting date. The Company granted 137,500 and 0 RSU awards, respectively, during the quarters ended January 31, 2012 and 2011. The fair market value per share of the outstanding awards was $16.43 and $19.49 as of January 31, 2012 and 2011, respectively. The aggregate amount charged to expense with respect to these awards was $0.2 million and $0.1 million for the quarters ended January 31, 2012 and 2011, respectively. The number of RSU awards outstanding as of January 31, 2012 and October 31, 2011 was 193,910 and 56,410, respectively.

12. Income Taxes

The provision for income taxes is determined by applying an estimated annual effective income tax rate to income from continuing operations before income taxes. The rate is based on the most recent annualized forecast of pretax income, permanent book versus tax differences and tax credits. The Company’s estimated annual effective tax rate for the three months ended January 31, 2012 is 39.8% compared to the estimated annual effective tax rate of 38.5% for the three months ended January 31, 2011. The increase is attributable in part to the mix of domestic and foreign results which were not present in the first quarter of 2011 results.

Prepaid and other current assets on the Consolidated Balance Sheets include an income tax receivable of $0.2 million as of January 31, 2012 and October 31, 2011.

The Company’s unrecognized tax benefit (UTB) is related to the Separation and state tax items regarding the interpretations of tax laws and regulations. The total UTB as of January 31, 2012 is $19.1 million. Of this, $8.5 million is recorded in Liability for uncertain tax positions and $10.6 million is recorded in Deferred income taxes (non-current assets) on the Consolidated Balance Sheets. The UTB includes $17.8 million for which the disallowance of such items would not affect the annual effective tax rate.

15

QUANEX BUILDING PRODUCTS CORPORATION

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (continued)

Judgment is required in assessing the future tax consequences of events that have been recognized in the Company’s financial statements or income tax returns. The final outcome of the future tax consequences of legal proceedings, if any, as well as the outcome of competent authority proceedings, changes in regulatory tax laws, or interpretation of those tax laws could impact the Company’s financial statements. The Company is subject to the effects of these matters occurring in various jurisdictions. The Company believes that it is reasonably possible that a decrease of approximately $3.5 million in the UTB may be recognized within the next twelve months as a result of a lapse in the statute of limitations.

13. Contingencies

Environmental

Quanex is subject to extensive laws and regulations concerning the discharge of materials into the environment and the remediation of chemical contamination. To satisfy such requirements, Quanex must make capital and other expenditures on an ongoing basis. The Company accrues its best estimates of its remediation obligations and adjusts such accruals as further information and circumstances develop. Those estimates may change substantially depending on information about the nature and extent of contamination, appropriate remediation technologies, and regulatory approvals. In accruing for environmental remediation liabilities, costs of future expenditures are not discounted to their present value, unless the amount and timing of the expenditures are fixed or reliably determinable. When environmental laws might be deemed to impose joint and several liability for the costs of responding to contamination, the Company accrues its allocable share of liability taking into account the number of parties participating, their ability to pay their shares, the volumes and nature of the wastes involved, the nature of anticipated response actions, and the nature of the Company’s alleged connections. The cost of environmental matters has not had a material adverse effect on Quanex’s operations or financial condition in the past, and management is not currently aware of any conditions that it believes are likely to have a material adverse effect on Quanex’s operations, financial condition or cash flows.

Total environmental reserves and corresponding recovery for the Company as of January 31, 2012 and October 31, 2011 were as follows:

		September 30,		September 30,
	January 31, 2012		October 31, 2011

Receivable for recovery of remediation costs2	$	11,860	$	12,304

¹  Reported in Accrued liabilities on the Consolidated Balance Sheets.

²  Reported in Accounts receivable and Other assets on the Consolidated Balance Sheets.

Currently, the Company’s ongoing remediation activities are at one of its subsidiaries, Nichols Aluminum-Alabama, LLC (NAA). NAA operates a plant in Decatur, Alabama that is subject to an Alabama Hazardous Wastes Management and Minimization Act Post-Closure Permit. Among other things, the permit requires NAA to remediate, as directed by the state, historical environmental releases of wastes and waste constituents. Consistent with the permit, NAA has undertaken various studies of site conditions and, during the first quarter of 2006, started a phased program to treat in-place free product petroleum that had been released underneath the plant. During the second quarter 2010, NAA submitted to the state the first component of its proposed workplan

16

QUANEX BUILDING PRODUCTS CORPORATION

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (continued)

for implementing a site-wide remedy. The full workplan was submitted to the state during the third quarter 2010, revised during the second quarter 2011 to reflect both additional sampling data and responses to state comments, and revised again in the fourth quarter 2011 in response to another round of state comments. Based on those plans, which remain subject to further comment, revision, and state approval, the Company’s remediation reserve at NAA’s Decatur plant is $12.8 million as of January 31, 2012. Approximately $1.3 million of the January 31, 2012 reserve represents administrative costs; the balance of $11.5 million represents estimated costs for investigation, studies, cleanup, and treatment. The reserve has not been discounted. NAA was acquired through a stock purchase in which the sellers agreed to indemnify Quanex and NAA for identified environmental matters related to the business and based on conditions initially created or events initially occurring prior to the acquisition. Environmental conditions are presumed to relate to the period prior to the acquisition unless proved to relate to releases occurring entirely after closing. The limit on indemnification is $21.5 million excluding legal fees. While the Company’s current estimates indicate it will not reach this limit, changing circumstances could result in additional costs or expense that are not foreseen at this time. In accordance with the indemnification, the indemnitors paid the first $1.5 million of response costs and have been paying 90% of ongoing costs. Based on its experience to date, its estimated cleanup costs going forward, and costs incurred to date as of January 31, 2012, the Company expects to recover from the sellers’ shareholders an additional $11.9 million which has not been discounted. Of that, $11.5 million is recorded in Other assets on the Consolidated Balance Sheets, and the balance is reflected in Accounts receivable on the Consolidated Balance Sheets. The undiscounted recovery from indemnitors as of October 31, 2011 was $12.3 million.

The Company’s final remediation costs and the timing of those expenditures will depend upon such factors as the nature and extent of contamination, the cleanup technologies employed, the effectiveness of the cleanup measures that are employed, and regulatory concurrences. While actual remediation costs, therefore, may be more or less than amounts accrued, the Company believes it has established adequate reserves for all probable and reasonably estimable remediation liabilities. It is not possible at this point to reasonably estimate the amount of any obligation for remediation in excess of current accruals because of uncertainties as to the extent of environmental impact, cleanup technologies, and concurrence of governmental authorities. The Company currently expects to pay the accrued remediation reserve through at least fiscal 2034, although some of the same factors discussed earlier could accelerate or extend the timing.

Other

From time to time, the Company and its subsidiaries are involved in various litigation matters arising in the ordinary course of their business. Although the ultimate resolution and impact of such litigation on the Company is not presently determinable, the Company’s management believes that the eventual outcome of such litigation will not have a material adverse effect on the overall financial condition, results of operations or cash flows of the Company.

14. Warranty Obligations

The Company’s estimated obligations for warranty are accrued concurrently with the revenue recognized. The Company makes provisions for its warranty obligations based upon historical experience incurred for such obligations adjusted, as necessary, for current conditions and factors. Due to the significant uncertainties and judgments involved in estimating the Company’s warranty obligations, including changing product designs, variance in customer installation process and future claims experience varying from historical claims experience, the ultimate amount incurred for warranty costs could change in the near and long-term from the current estimate.

15. Fair Value Measurement of Assets and Liabilities

The Company’s investments that are measured at fair value on a recurring basis are categorized below using the fair value hierarchy. The fair value hierarchy has three levels based on reliability of inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values obtained from readily available pricing sources for comparable instruments and Level 3 includes fair values requiring measurement without observable market values that would require a high level of judgment to determine fair value. The following table summarizes assets measured on a recurring basis based on the fair value hierarchy:

		September 30,		September 30,
	Quoted Prices in Active Markets for Identical Assets (Level 1)
	January 31, 2012		October 31, 2011
	(In thousands)
Money Market Fund investments	$	76,507	$	80,688
Pension plan assets		14,204		14,004
Total	$	90,711	$	94,692

The Company holds Money Market Fund investments that are classified as cash equivalents and pension plan assets measured at fair value based on active market quotations, which represent Level 1 inputs. As of January 31, 2012 and October 31, 2011, the Company did not have any assets or liabilities measured at fair value on a recurring basis in Level 2 or Level 3.

On May 27, 2010, the Board of Directors approved a stock repurchase program of 1.0 million shares, and on August 25, 2011, the Board of Directors authorized an additional 1.0 million shares to this program. The objectives of this program are to manage the dilution created by shares issued under stock-based compensation plans and to repurchase shares opportunistically. The Company records treasury stock purchases under the cost method whereby the entire cost of the acquired stock is recorded as treasury stock. The Company uses a moving-average method on the subsequent reissuance of shares, and any resulting proceeds in excess of cost are credited to additional paid in capital while any deficiency is charged to retained earnings.

As of October 31, 2011, the number of shares in treasury stock was 1,035,288. During the three months ended January 31, 2012, the Company purchased 94,337 shares at a cost of $1.3 million partially offset by shares issued for stock option exercises and restricted stock grants for a net increase to the number of shares in treasury stock to 1,043,891 as of January 31, 2012. Since inception of the program, Quanex has purchased 1,094,337 shares through January 31, 2012. The remaining shares authorized for repurchase in the program was 905,663 as of January 31, 2012.

17. Other Income (Expense)

During the three months ended January 31, 2012, the Company incurred $0.1 million of transaction gains which are included in determining net income primarily related to Edgetech’s international operations and foreign currency denominated exposures. There are no transaction gains or losses during the three months ended January 31, 2011.

18. Restructuring and Related Activities

In November 2011, management committed to a plan to close its Barbourville, Kentucky facility (Barbourville) which is included in the Engineered Products segment. The consolidation plan, in part, calls for the permanent closing of Barbourville. The equipment used to manufacture the single seal spacer system will be relocated to the Company’s Cambridge, Ohio facility. The Company believes this consolidation will allow it to better serve customers through streamlined operations. The consolidation of operations and the subsequent closure of the Barbourville facility are expected to be completed during 2012.

Under ASC Topic 712, “Compensation — Nonretirement Postemployment Benefits”, the Company is required to record charges for contractual termination benefits and other ongoing benefit arrangements when it is probable that employees will be entitled to benefits under the contract’s terms and the amount can be reasonably estimated. The Company determined that certain severance pay qualifies as either a contractual termination benefit or an ongoing benefit arrangement, and accordingly has recognized $2.1 million in estimated severance during the three months ended January 31, 2012. Severance will be paid out during the remainder of 2012, provided employees continue their employment until their planned exit dates.

Under ASC Topic 420, “Exit or Disposal Cost Obligations,” the Company is required to record charges for one-time employee termination benefits, contract termination costs, and other associated costs as incurred. During the quarter ended January 31, 2012, facilities consolidation costs of $0.4 million were expensed as incurred.

All other costs related to the closure and relocation activities are being recorded as incurred, when they meet the definition of a liability, and they are included in the statements of income as selling, general, and administrative expenses, in accordance with the applicable accounting guidance. Cumulative costs incurred as of January 31, 2012 total $2.5 million. Total expected costs of $9 million for the project are comprised of approximately $4 million for employee-related costs and $5 million for plant closure, equipment moving and set up costs, substantially all of which will be charged to selling, general and administrative expense. Management’s estimates of costs, planned exit dates for employees and the timing of the project completion are subject to change.

In February 2012, the Company and the union reached an agreement to pay a one-time incentive bonus to employees upon their planned exit date termination, providing certain performance criteria are met. The salaried employees are being offered the same one-time incentive bonus under the same terms as the union employees. The incentive bonus expense will be recognized ratably over the remaining performance period and is included in the total employee-related cost number above.

Description of Business

On December 12, 2007, Quanex Building Products Corporation was incorporated in the state of Delaware as a subsidiary of Quanex Corporation to facilitate the separation of Quanex Corporation’s vehicular products and building products businesses. The separation occurred on April 23, 2008 through the spin-off of Quanex Corporation’s building products business to its shareholders immediately followed by the merger of Quanex Corporation (consisting principally of the vehicular products business and all non-building products related corporate accounts) with a wholly-owned subsidiary of Gerdau S.A. (Gerdau).

The spin-off and subsequent merger is hereafter referred to as the “Separation”. For purposes of describing the events related to the Separation, as well as other events, transactions and financial results of Quanex Corporation and its subsidiaries related to periods prior to April 23, 2008, the term “the Company” refers to Quanex Building Products Corporation’s accounting predecessor, Quanex Corporation. In March 2011, the Company acquired Edgetech I.G., Inc. and its German subsidiary. Headquartered in Cambridge, Ohio, Edgetech has three manufacturing facilities (U.S., U.K., and Germany) that produce and market a full line of insulating glass spacer systems for window and door customers in North America and abroad.

In November 2011, management committed to a plan to consolidate its Insulating Glass (“IG”) spacer manufacturing facility in Barbourville, Kentucky into its IG spacer manufacturing facility in Cambridge, Ohio. In 2010, management closed its start-up facility in China due to the contraction of demand and the Company’s ability to serve the overseas thin film solar panel market from its North American operations. Accordingly, the China assets and liabilities, results of operations and cash flows are reported as discontinued operations for all periods presented. Unless otherwise noted, all discussions reflect only continuing operations.

Overview

Quanex continues to operate in difficult end markets and window shipments have dropped to new lows. Housing starts and window shipments have declined significantly in recent years from record highs in 2005 of 2.1 million and 70.5 million units, respectively, to an estimated 0.6 million and 38.4 million, respectively, in 2011. The first fiscal quarter saw some positive signs for the overall housing market including rising housing starts and falling inventory levels of new homes. While the regional level data suggests this might be more than simply the benefit of a mild winter, it will be difficult to determine until we get into the typical building season in our fiscal second quarter. The headwinds that have persisted throughout the downturn, declining housing prices, falling consumer confidence and reduced homeowner lending continue, albeit to a lesser extent. It may take structural changes to establish a reliable recovery. The best industry comparison available for the Company’s first fiscal quarter is window shipments for the fourth calendar quarter, which were estimated to be down 5% versus the same quarter of the previous year. This may be counter to the recent positive news surrounding housing, but it was to be expected in our specific industry as a result of the demand pull-forward in advance of the $1,500 window tax credit that expired on December 31, 2010. The 2012 figures include financial results from the March 2011 acquisition of Edgetech. Edgetech contributed $18.9 million of Net sales for the first quarter of fiscal 2012 while the remaining Quanex businesses’ Net sales declined $17.1 million or 10.7% for the three months ended January 31, 2012 compared to the same 2011 period; the majority of the decline was realized within the Aluminum Sheet Products segment both from reduced volume and lower global aluminum prices. Same store Net sales from Engineered Products for the quarter ended January 31, 2012 were down $3.5 million or 4.1% compared to the previous year, a direct result of the demand pull forward experienced last year. The operating loss in the first quarter of 2012 was $3.6 million more than the year ago quarter, all of which is tied to the lower volume and aluminum prices experienced in the aluminum segment as Engineered Products actually recognized a $2.5 million dollar improvement in operating income for the quarter.

The Company believes that consumer demand for more energy efficient products and its ability to provide innovative window and door systems in addition to stand-alone components will fuel long-term organic growth incremental to the eventual housing market recovery. The integration of Edgetech into the Engineered Products sales and marketing organization was completed in September 2011 and it is clear that Quanex is already a stronger customer-focused organization as a result. This added strength will benefit Quanex whether the housing market recovery takes hold either sooner or later. We remain bullish long-term as demographics for long-term housing demand in the U.S. remain favorable when factoring the projected population increase and continuing immigration. The Company believes taking a disciplined approach to the way it seeks new business opportunities will make it a

23

more successful company and a stronger competitor by offering a broader range of customers a more robust slate of systems, products, services and solutions while intensely focusing on continuously improving customer service. Additionally, the Company is elevating its programs to develop more energy efficient products. These programs and initiatives, coupled with an eventual return to a more normal housing market and residential repair and remodel market, will benefit Quanex over the long term.

Business Segments

Quanex has two reportable segments: Engineered Products and Aluminum Sheet Products. The Engineered Products segment produces systems, finished products, and components serving the OEM residential window and door industry, while the Aluminum Sheet Products segment produces mill finished and coated aluminum sheet serving the broader residential building products markets. The primary market drivers of both segments are residential repair and remodel activity and new home construction.

For financial reporting purposes, three of the Company’s four operating segments, Homeshield, Insulating Glass (“IG”) and Mikron, have been aggregated into the Engineered Products reportable segment. The remaining operating segment, Aluminum Sheet Products (Nichols Aluminum), is reported as a separate reportable segment. Corporate & Other is comprised of corporate office expenses and certain inter-division eliminations. The sale of products between segments is recognized at market prices. The financial performance of the operations is based upon operating income. The segments follow the accounting principles described in Item 1, Note 1 to the consolidated financial statements of the Company’s 2011 Form 10-K. The two reportable segments value inventory on a FIFO or weighted-average basis while the LIFO reserve relating to those operations accounted for under the LIFO method of inventory valuation is computed on a consolidated basis in a single pool and treated as a corporate item.

¹ Exclusive of items shown separately below.

Engineered Products is focused on providing window and door OEM customers with fenestration components, products and systems. Key end markets are residential remodel and repair and new home construction. Engineered Products’ first quarter 2012 Net sales were $99.4 million, compared to $84.0 million a year ago, and included Net sales of $18.9 million at Edgetech which was acquired on March 31, 2011. First fiscal quarter 2012 same store Net sales were down 4.1% from the year ago quarter which benefited from a pull-forward of demand as a result of a $1,500 energy efficient window tax credit program that expired on December 31, 2010. There were no similar tax credits in the first quarter of 2012. Quanex believes there is value in measuring its sales performance against industry indices. Engineered Products compares its sales to US window shipments as reported by Ducker Worldwide, a market intelligence firm. For the twelve months ended January 31, 2012, Engineered Products’ Net sales before contributions from acquisitions were down 2.4% compared to the previous twelve months, versus US window shipments that were down approximately 7%. As expected, the industry experienced a more normal low seasonal volume demand during the first quarter 2012; uncertainty remains as to what level the demand will be during the remainder of 2012. There were clearly favorable signs in housing in our first quarter and time will tell as to how much can be attributed to the mild winter experienced thus far versus the beginnings of a housing recovery. The long-term recovery is likely to take hold once changes in housing prices, credit availability and consumer confidence turn to the positive.

24

Net sales less Cost of sales (Contribution margin) at Engineered Products for the three months ended January 31, 2012 compared to the same period of last year improved by $8.8 million including Edgetech’s contribution of $5.1 million. Net sales less Cost of sales as a percent of Net sales for the quarter ended January 31, 2012 is above the same 2011 period (with and without acquisitions) even with the weak market and negative pressure on volume this most recent quarter. The reduced revenues were more than offset by the combination of pricing initiatives, cost controls and productivity improvements, which strengthened margins as well as there being a lower amount of unusual items in the first quarter of 2012 as compared to the previous year. One such pricing initiative was the oil-based raw material surcharge initiated effective May 1, 2011 at Truseal, one of the Company’s insulating glass spacer operations. The surcharge helped Truseal offset the higher cost of butyl, a key raw material of the business that is highly correlated to the price of oil. In 2011, Quanex consolidated facilities in Kent, Washington and closed a facility in The Dalles, Oregon. Of the $3.1 million in 2011 plant consolidation costs, $1.3 million is recognized in Cost of sales. The first quarter of fiscal 2011 also includes $2.1 million of warranty reserve costs which contributed to the year over year improvement in margins.

Selling, general and administrative costs increased for the 2012 first quarter primarily from the addition of Edgetech, which had $3.8 million of expenses. Additionally, first quarter 2012 Selling, general and administrative costs included expenses of $2.5 million associated with the Company’s IG spacer consolidation program compared to $1.4 million (included in the total $3.1 million discussed above) in first quarter 2011 related to plant consolidations. Selling, general and administrative costs for the full fiscal year of 2012 is expected to increase over fiscal 2011 as a full twelve months of expense associated with Edgetech is realized.

Depreciation and amortization has increased for the 2012 quarter compared to 2011 primarily due to the addition of Edgetech. Depreciation and amortization associated with Edgetech was $2.0 million for the three months ended January 31, 2012. Depreciation and amortization decreased for the first quarter 2012 compared to 2011 by $0.3 million (included in the $3.1 million discussed above) because of accelerated depreciation related to the plant consolidations that was recognized in the first quarter of 2011. Depreciation and amortization for the full fiscal year of 2012 is expected to increase over fiscal 2011 as a full twelve months of expense associated with the recognition of Edgetech intangible assets and the step-up in Edgetech’s tangible assets is realized going forward.

Engineered Products’ first quarter 2012 operating income was $1.8 million compared to an operating loss of $0.7 million a year ago. The first quarter of fiscal 2012 saw $2.5 million of expense associated with the Company’s IG spacer consolidation program compared to $5.2 million of combined facility consolidation and warranty reserve costs in the first fiscal quarter of last year, thereby improving margins. Similar to Contribution margin, Operating income for the first fiscal quarter of 2012 (with and without acquisitions) was better than the comparable period of 2011 even in the face of weaker window demand. All of the actions around pricing, cost controls, productivity and reduced unusual items resulted in positive Operating income in what is typically a seasonally difficult quarter.

On November 7, 2011, the Company announced a consolidation program for its IG spacer manufacturing facility in Barbourville, Kentucky into its IG spacer manufacturing facility in Cambridge, Ohio. At the completion of the consolidation, which is expected in 2012, the Barbourville facility will be permanently closed. The consolidation remains on budget and on schedule. Total cash spending associated with the consolidation plan are estimated at about $16.0 million (excludes a pre-tax, non-cash impairment charge of $1.6 million taken in the fourth quarter 2011). Of the $16.0 million of cash, total expenses (to be recognized in Selling, general and administrative costs) are expected to be $9.0 million for the project, comprised of approximately $4.0 million for employee-related costs and $5.0 million for plant closure, equipment moving and set up costs, substantially all of which will be charged to selling, general and administrative expense. Management’s estimates of costs, planned exit dates for employees and the timing of the project completion are subject to change. The Company expects an annual pre-tax cash savings of $9.0 million, once the consolidation is concluded.

Engineered Products’ long-term organic growth programs are focused on driving profitable growth through one sales and marketing team that is intensely focused on driving continuous improvement of customer satisfaction. The Company believes this will drive profitable growth at Engineered Products by furthering the goal of becoming the leading energy efficiency expert in the market by offering customers state-of-the-art engineering, design and marketing support. Engineered Products is in the early stages of this long-term organic growth initiative but believes it will have a meaningful impact on its long-term growth and profitability. The Company will continue to incur expenses and to invest in additional resources at Engineered Products to support this organic growth effort.

¹  Exclusive of items shown separately below.

The primary market drivers for the Aluminum Sheet Products segment are residential repair and remodel activity and new home construction (together approximately 70% of the segment’s sales) and transportation (approximately 20% of the segment’s sales) markets.

The decrease in net sales at the Aluminum Sheet Products segment for the three months ended January 31, 2012 was the result of a 15.3% decrease in shipments and a 1.9% decrease in average selling price compared to the same period of 2011. Shipments were down from the year ago quarter in part due to weaker end demand because of the absence of the window tax credit program in the first quarter of 2012 compared to the available program in the year ago quarter. Average selling price decreased primarily due to lower London Metal Exchange (LME) aluminum prices in the comparative period. LME aluminum prices are the most commonly used index for correlating aluminum sheet prices. The Aluminum Association, which tracks aluminum industry shipments of sheet products, reported non-can sheet aluminum shipments in the first quarter up 3% from a year ago, while Aluminum Sheet Products’ shipments were down. Part of the Company’s underperformance versus the industry continues to be attributed to relatively weaker building and construction demand, where Quanex has a sizable presence, compared to stronger distribution and transportation demand, where Quanex has a relatively smaller presence. Compared to the Company’s sequential fourth quarter of 2011, shipped pounds were down 21.3 million pounds, which is not unusual for the historically lowest shipping quarter of the year.

Selling, general and administrative costs increased by $0.3 million for the three months ended January 31, 2012 compared to the same 2011 period. Selling, general and administrative costs are expected to be noticeably higher in the second quarter of 2012 compared to the previous year due to the ongoing strike at two of the segment’s facilities (see further information below). The higher costs are directly associated with the negotiating activities themselves as well as the fact that the salary workforce has stepped in to continue to keep the two facilities operating. This generally results in additional costs being required for the additional activities or backfill situations in certain cases. Higher selling, general and administrative costs are likely to continue for as long as the strike persists.

Depreciation and amortization has increased for the quarter and in 2012 compared to 2011 primarily due accelerated depreciation related to the reduction of an asset’s remaining useful life.

Operating income decreased at the Aluminum Sheet Products segment for the three months ended January 31, 2012, compared to prior year due to lower shipped pounds and lower spread. The operating loss of $5.5 million reflected the weaker end market demand and a reduced spread (sales price less material costs divided by pounds) compared to the year ago quarter. London Metal Exchange aluminum prices fell through the quarter, which in turn, lowered the spread. Spread was down 6.2% from the year ago quarter and down 5.6% from the

26

sequential fourth quarter, primarily due to the average selling price that fell faster than the average material costs. Nichols is a high fixed cost business, so as its shipments drop, its ability to substantially reduce operating costs is limited. The segment’s operating income and margins are impacted by changes in LME aluminum prices as its spread is correlated with aluminum prices over time. Declines in aluminum prices generally result in spread compression; however, as aluminum prices rebound, spread and profits generally expand.

On January 20, 2012, Nichols experienced a strike with its union employees at two of its facilities. Negotiations for a new contract are ongoing, and management along with temporary employees are operating the two facilities while continuing to meet ongoing customer needs. The strike had no material financial impact on first quarter results. A protracted strike could have a material financial impact; however, all efforts are being made to continue to supply customers with product with the lowest amount of incremental costs possible.

Corporate and Other operating expenses, which are not in the segments mentioned above, include intersegment eliminations, the consolidated LIFO inventory adjustments (calculated on a combined pool basis), if any, and corporate office expenses. Net sales amounts represent intersegment eliminations between the Engineered Products segment and the Aluminum Sheet Products segment with an equal and offsetting elimination in Cost of sales.

Selling, general and administrative costs were essentially flat year over year. Included in the results for the three months ended January 31, 2011, was $1.1 million of transaction related costs associated with the acquisition of Edgetech during fiscal 2011 with no comparative costs in 2012. The first fiscal quarter of 2012 expenses have increased by $0.6 million associated with the development and rollout of a company-wide ERP system. The Company initiated this ERP project (Project Quest) in 2011 to support the drive for long-term organic growth by bringing the myriad of disparate systems currently existing throughout the Company together into a single standard system supported by a common set of processes. During fiscal 2011, the Company recognized $1.5 million of Project Quest expense and expects an increase of expense in fiscal 2012 primarily due to a full twelve months of activity in 2012 as well as the initial conversions of the legacy systems. The current plan anticipates the conversion of all of the Company’s disparate systems to a single system over a period of at least three years. Project Quest depreciation expense of $0.1 million was incurred in the first fiscal quarter of 2012 in conjunction with the implementation of the human capital management module of the ERP system. As the new ERP system is placed in service (replacing the legacy systems) the Company expects depreciation expense to increase. Selling, general and administrative costs have increased during the first fiscal quarter of 2012 compared to the same year ago quarter due to higher stock based compensation expense associated with employees who became retirement eligible.

Other items

Other, net typically includes interest income earned on the Company’s cash and equivalents and, beginning with the acquisition of Edgetech in March 2011, foreign currency transaction gains and losses. Other income increased by $0.1 million during the three months ended January 31, 2012 compared to the respective 2011 periods with the quarter-to-date January 2012 results include foreign currency transaction gains of $0.1 million.

27

The Company’s estimated annual effective tax rate for the three months ended January 31, 2012 is 39.8%, compared to 38.5% for the three months ended January 31, 2011. The increase is attributable in part to the mix of domestic and foreign results which were not in the first quarter of 2011.

Liquidity and Capital Resources

The Company’s principal sources of funds are cash on hand, cash flow from operations, and borrowings under its $270.0 million Senior Unsecured Revolving Credit Facility (the Credit Facility). As of January 31, 2012, the Company has a solid liquidity position, comprised of cash and equivalents and adequate availability under the Company’s Credit Facility. The Company has $81.7 million of cash and equivalents, $173.1 million of current availability under the revolving credit facility and minimal debt of $1.6 million as of January 31, 2012. Even with the difficult economy and the Company’s difficult end markets, the Company continues to generate strong operating cash flows. Cash equivalents for the three months ended January 31, 2012 decreased by $7.9 million to $81.7 million primarily due to capital expenditures, and to a lesser extent purchases of treasury stock and dividends. The Company’s strategy for cash uses is to make strategic acquisitions that fit its fenestration vision, invest in organic growth opportunities, fund the cash dividend and make ongoing purchases of Quanex stock.

The Company’s excess cash and equivalents are invested only in large, overnight money market funds due to the conditions of the financial market. The funds are diversified by security type across Treasuries, Government Agencies and Prime Corporate. These funds are all AAA-rated, approved by the NAIC and compliant with Rule 2A-7 of the Investment Company Act of 1940. The Company’s current investments are diversified across multiple institutions that the Company believes to be financially sound. The Company intends to remain in highly rated money market funds, financial institutions and treasuries following a prudent investment philosophy. From time to time, to prepare for potential disruption in the money markets, the Company may temporarily move funds into operating bank accounts of highly-rated financial institutions to meet on-going operational liquidity requirements. The Company had no material losses on its cash and marketable securities investments.

The Credit Facility was executed on April 23, 2008 and has a five-year term. Proceeds from the Credit Facility may be used to provide availability for acquisitions, working capital, capital expenditures, and general corporate purposes. Borrowings under the Credit Facility bear interest at a spread above LIBOR based on a combined leverage and ratings grid. There are certain limitations on additional indebtedness, asset or equity sales, and acquisitions. Dividends and other distributions are permitted so long as after giving effect to such dividend or stock repurchase, there is no event of default. Under the Credit Facility, the Company is obligated to comply with certain financial covenants requiring the Company to maintain a Consolidated Leverage Ratio of no more than 3.25 to 1 and a Consolidated Interest Coverage Ratio of no less than 3.00 to 1. As defined by the indenture, the Consolidated Leverage Ratio is the ratio of consolidated indebtedness as of such date to consolidated EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) for the previous four fiscal quarters, and the Consolidated Interest Coverage Ratio is the ratio of consolidated EBITDA to consolidated interest expense, in each case for the previous four consecutive fiscal quarters. EBITDA is defined by the indenture to include proforma EBITDA of acquisitions and to exclude certain items like goodwill and intangible asset impairments and certain other non-cash charges and non-recurring items. The availability under the Credit Facility is a function of both the facility amount utilized and meeting covenant requirements. Additionally, the availability of the Credit Facility is dependent upon the financial viability of the Company’s lenders. The Credit Facility is funded by a syndicate of nine banks, with three banks comprising over 55% of the commitment. If any of the banks in the syndicate were unable to perform on their commitments to fund the facility, the availability under the Credit Facility could be reduced; however, the Company has no reason to believe that such liquidity will be unavailable or decreased.

28

As of January 31, 2012, the Company had no borrowings under the Credit Facility, and the Company was in compliance with all Credit Facility covenants as seen by the table below:

	September 30,	September 30,
At January 31, 2012	Required	Actual
Consolidated Interest Coverage Ratio	No less than 3.00 to 1	122.65 to 1
Consolidated Leverage Ratio	No more than 3.25 to 1	0.14 to 1

Although there were no borrowings on the Credit Facility and only $5.6 million of outstanding letters of credit under the Credit Facility, the aggregate availability under the Credit Facility was limited by the Consolidated Leverage Ratio resulting in an availability of $173.1 million at January 31, 2012. Because the Consolidated Leverage Ratio is based on a rolling twelve months of EBITDA, a change in future earnings will impact the amount available under the Credit Facility in future quarters, absent any pro-forma EBITDA benefit from any potential acquisitions. To have access to the full availability of the $270.0 million Credit Facility, the Company must have a minimum rolling EBITDA of approximately $84 million for the previous four fiscal quarters. Actual rolling EBITDA for the previous four fiscal quarters was $55.7 million as of January 31, 2012. Increased earnings for any future periods could increase availability under the Credit Facility; conversely, reduced earnings for any future periods could adversely impact the amount available under the Credit Facility in future quarters, absent any pro-forma EBITDA benefit from any potential acquisitions.

The Company believes that it has sufficient funds and adequate financial resources available to meet its anticipated liquidity needs. The Company also believes that cash balances and cash flow from operations will be sufficient in the next twelve months and foreseeable future to finance anticipated working capital requirements, capital expenditures, debt service requirements, environmental expenditures, and dividends.

The Company’s working capital was $135.1 million on January 31, 2012 compared to $140.3 million on October 31, 2011. Working capital declined by $5.2 million from a reduction in conversion capital (accounts receivable plus inventory less accounts payable) of $4.7 million as the Company’s business seasonally contracts in the first quarter compared to the previous fourth fiscal quarter. Within conversion capital, inventory increased by $8.3 million reflecting strategic increases in levels of finished goods held, including builds to support the upcoming IG plant consolidation, to enhance customer service levels and in anticipation of the building season.

The following table summarizes the Company’s cash flow results from continuing operations for the three months ended January 31, 2012 and 2011:

		September 30,			September 30,
	Three Months Ended January 31,
	2012			2011
	(In millions)
Cash flows from operating activities	$	2.1		$	0.7
Cash flows from investing activities	$	(8.0	)	$	(3.4	)
Cash flows from financing activities	$	(2.4	)	$	(2.0	)

Highlights from the Company’s cash flow results for the three months ended January 31, 2012 and 2011 are as follows:

Operating Activities – Continuing Operations

Cash provided by operating activities from continuing operations for the first three months of fiscal 2012 increased by $1.4 million compared to the same period last year. This increase is primarily attributable to lower annual incentive payments during the three months ended January 31, 2012 compared to the same 2011 period, offset by a decrease in conversion capital. Conversion capital during the three months ended January 31, 2012 provided $3.2 million of cash (compared to a $7.5 million source of cash in the same 2011 period) primarily attributable to slower turns of accounts receivable from customers not taking advantage of payment term discounts. Despite the continued overall weak condition of the Company’s end markets, the Company’s seasonally weakest quarter and restructuring charges, the Company generated positive cash flow during the three months ended January 31, 2012. The Company expects to generate additional operating cash flow during the balance of fiscal 2012 as the Company’s second half of its fiscal year is typically seasonally stronger.

29

Investing Activities – Continuing Operations

Cash used in investing activities from continuing operations during the three months ended January 31, 2012, increased $4.6 million compared to the same period in 2011. Of this, $3.9 million of the increase related to increased capital spending. In the first three months of fiscal 2012, the Company incurred $2.8 million associated with the rollout of its company-wide ERP system (Project Quest), initiated in March 2011. The current plan anticipates the conversion of all of the Company’s disparate systems to a single system over a period of at least three years. The Company also incurred capital expenditures of $1.8 million during January 31, 2012 related to the consolidation of its IG businesses. The Company expects total 2012 capital expenditures to approximate $49.0 million, including IG consolidation capital spending of approximately $7.0 million and Project Quest capital spending of $13.0 million. At January 31, 2012, the Company had commitments of approximately $9.2 million for the purchase or construction of capital assets. The Company plans to fund these capital expenditures through cash flow from operations.

Financing Activities – Continuing Operations

The Company used $2.4 million for financing activities from continuing operations during the three months ended January 31, 2012, compared to $2.0 million in the same prior year period. During the three months ended January 31, 2011, the Company received a $0.4 million repayment by the China facility (discontinued cash outflow) to its Quanex parent (offsetting financing cash inflow in continuing operations). The Company spent $0.2 million less on purchases of Quanex common stock in 2012 compared to 2011 which is offset by lower issuances of common stock from option exercises by $0.2 million.

Discontinued Operations

Cash flows from discontinued operations represent results related to the Company’s start-up facility in China that was closed in fiscal year 2010. Residual 2011 cash flows represent wind-up activities, including repayment by the China facility (discontinued cash outflow) to its Quanex parent (offsetting financing cash inflow in continuing operations).

Critical Accounting Estimates

In preparing the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, the Company’s management must make decisions which impact the reported amounts and the related disclosures. Such decisions include the selection of the appropriate accounting principles to be applied and assumptions on which to base estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, including those related to revenue recognition, allowances for doubtful accounts, inventory, long-lived assets, environmental contingencies, insurance, U.S. pension and other post-employment benefits, litigation and contingent liabilities, warranty obligations and income taxes. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. The Company’s management believes the critical accounting estimates listed and described in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of the Company’s 2011 Annual Report on Form 10-K are the most important to the fair presentation of the Company’s financial condition and results. These policies require management’s significant judgments and estimates in the preparation of the Company’s consolidated financial statements. There have been no significant changes to the Company’s critical accounting estimates since October 31, 2011.

New Accounting Pronouncements

In June 2011, the FASB issued Accounting Standards Update No. 2011-05 (ASU 2011-05), Presentation of Comprehensive Income. This amendment will require companies to present the components of net income and other comprehensive income either as one continuous statement or as two consecutive statements. It eliminates the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity. The amended guidance, which must be applied retroactively, is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 (November 1, 2012 for the Company), with earlier adoption

30

permitted. ASU 2011-05 impacts presentation only and will have no effect on the Company’s financial condition, results of operations or cash flows. In December 2011, the FASB issued Accounting Standards Update No. 2011-12 (ASU 2011-12), “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05.” ASU 2011-12 deferred the effective date of ASU 2011-05 related to the presentation of reclassifications of items out of accumulated other comprehensive income. All other requirements of ASU 2011-05 were not affected by ASU 2011-12.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The following discussion of the Company and its subsidiaries’ exposure to various market risks contains “forward looking statements” that involve risks and uncertainties. These projected results have been prepared utilizing certain assumptions considered reasonable in light of information currently available to the Company. Nevertheless, because of the inherent unpredictability of interest rates, foreign currency rates and metal commodity prices as well as other factors, actual results could differ materially from those projected in such forward looking information. The Company does not use derivative financial instruments for speculative or trading purposes.

Interest Rate Risk

The Company and its subsidiaries have a Credit Facility and other long-term debt which subject the Company to the risk of loss associated with movements in market interest rates.

At January 31, 2012, the Company had fixed-rate debt totaling $0.1 million or 9% of total debt, which does not expose the Company to the risk of earnings loss due to changes in market interest rates. The Company and certain of its subsidiaries’ floating-rate obligations totaled $1.5 million, or 91% of total debt at January 31, 2012. Based on the floating-rate obligations outstanding at January 31, 2012, a one percent increase or decrease in the average interest rate would result in a change to pre-tax interest expense of approximately $15 thousand.

Commodity Price Risk

Within the Aluminum Sheet Products segment, the Company uses various grades of aluminum scrap as well as minimal amounts of prime aluminum ingot as raw materials for its manufacturing processes. The price of this raw material is subject to fluctuations due to many factors in the aluminum market. In the normal course of business, Nichols Aluminum enters into firm price sales commitments with its customers. In an effort to reduce the risk of fluctuating raw material prices, Nichols Aluminum enters into firm price raw material purchase commitments (which are designated as “normal purchases” under ASC Topic 815 “Derivatives and Hedging” (ASC 815)) as well as option contracts on the London Metal Exchange (LME). The Company’s risk management policy as it relates to these LME contracts is to enter into contracts to cover the raw material needs of the Company’s committed sales orders, to the extent not covered by fixed price purchase commitments.

Nichols Aluminum maintains a balanced metals book position which excludes a normal operational inventory level. This operating inventory level as a matter of practice is currently not hedged against material price (LME) movements. This practice reflects that over the commodity price cycle, no gain or loss is incurred on this inventory. Through the use of firm price raw material purchase commitments and LME contracts, the Company intends to protect cost of sales from the effects of changing prices of aluminum. To the extent that the raw material costs factored into the firm price sales commitments are matched with firm price raw material purchase commitments, changes in aluminum prices should have no effect. During fiscal 2012 and 2011, the Company primarily relied upon firm price raw material purchase commitments to protect cost of sales tied to firm price sales commitments. At January 31, 2012, there were 197 open LME forward contracts associated with metal exchange derivatives covering notional volumes of 10.9 million pounds with a fair value mark-to-market net gain of approximately $0.7 million. At January 31, 2012 there were 38 open LME short sale contracts associated with metal exchange derivatives covering notional volumes of 2.1 million pounds with a fair value mark-to-market net gain of approximately $23 thousand. These contracts were not designated as hedging instruments, and any mark-to-market net gain or loss was recorded in Cost of sales with the offsetting amount reflected as a current asset or liability on the balance sheet. At October 31, 2011, there were 62 open LME forward contracts associated with metal exchange derivatives covering notional volumes of 3.4 million pounds with a fair value mark-to-market net loss of approximately $0.1 million. In addition, at October 31, 2011 there were 97 open LME short sale contracts associated with metal exchange derivatives covering notional volumes of 5.3 million pounds with a fair value mark-to-market net gain of approximately $0.1 million.

31

Within the Engineered Products segment, polyvinyl resin (PVC) is the significant raw material consumed during the manufacture of vinyl extrusions. The Company has a monthly resin adjuster in place with the majority of its customers and resin supplier that is adjusted based upon published industry resin prices for the prior month. This adjuster effectively shares the base pass-through price changes of PVC with the Company’s customers commensurate with the market at large. The Company’s long-term exposure to changes in PVC prices is thus significantly reduced due to the contractual component of the resin adjuster program; however, there is a level of exposure to short-term volatility due to the one month lag.

Effective May 1, 2011, one of the Company’s warm edge, insulating glass spacer divisions initiated an oil-based materials surcharge. The surcharge helps offset the rising cost of butyl and other oil-based raw materials, pricing of which are highly correlated to the price of oil. The surcharge is in place with the majority of its customers and is adjusted monthly based upon the 90 day average published price for Brent crude. The oil-based raw materials purchased by the company are subject to similar pricing schemes. Therefore, the Company’s long-term exposure to changes in oil-based raw materials prices is significantly reduced due to the contractual component of the surcharge program.

Foreign Currency Rate Risk

The Company’s international operations have exposure to foreign currency rate risks primarily due to fluctuations in the British Pound, the Canadian dollar and Euro. From time to time, the Company enters into foreign exchange contracts associated with its exposures from operations to manage a portion of the foreign currency rate risk.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and Chief Financial Officer, the Company has evaluated the effectiveness of its disclosure controls and procedures pursuant to Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (1934 Act) as of January 31, 2012. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of January 31, 2012, the disclosure controls and procedures are effective.

Changes in Internal Control over Financial Reporting

During the period covered by this report, the Company consolidated its division-level payroll processes into a standard company-level process and converted the payroll processing onto a new platform. Management believes this consolidation and platform conversion constitutes a change in the Company’s internal control over financial reporting. Based on the additional procedures and review of processes that were performed, management continues to believe that its internal controls over financial reporting are adequate.

There have been no other changes in internal controls over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the 1934 Act) during the most recent fiscal quarter that have materially affected or are reasonably likely to materially affect the Company’s internal control over financial reporting.

Restructuring and Related Activities

18. Restructuring and Related Activities

In November 2011, management committed to a plan to close its Barbourville, Kentucky facility (Barbourville) which is included in the Engineered Products segment. The consolidation plan, in part, calls for the permanent closing of Barbourville. The equipment used to manufacture the single seal spacer system will be relocated to the Company’s Cambridge, Ohio facility. The Company believes this consolidation will allow it to better serve customers through streamlined operations. The consolidation of operations and the subsequent closure of the Barbourville facility are expected to be completed during 2012.

Under ASC Topic 712, “Compensation — Nonretirement Postemployment Benefits”, the Company is required to record charges for contractual termination benefits and other ongoing benefit arrangements when it is probable that employees will be entitled to benefits under the contract’s terms and the amount can be reasonably estimated. The Company determined that certain severance pay qualifies as either a contractual termination benefit or an ongoing benefit arrangement, and accordingly has recognized $2.1 million in estimated severance during the three months ended January 31, 2012. Severance will be paid out during the remainder of 2012, provided employees continue their employment until their planned exit dates.

Under ASC Topic 420, “Exit or Disposal Cost Obligations,” the Company is required to record charges for one-time employee termination benefits, contract termination costs, and other associated costs as incurred. During the quarter ended January 31, 2012, facilities consolidation costs of $0.4 million were expensed as incurred.

All other costs related to the closure and relocation activities are being recorded as incurred, when they meet the definition of a liability, and they are included in the statements of income as selling, general, and administrative expenses, in accordance with the applicable accounting guidance. Cumulative costs incurred as of January 31, 2012 total $2.5 million. Total expected costs of $9 million for the project are comprised of approximately $4 million for employee-related costs and $5 million for plant closure, equipment moving and set up costs, substantially all of which will be charged to selling, general and administrative expense. Management’s estimates of costs, planned exit dates for employees and the timing of the project completion are subject to change.

In February 2012, the Company and the union reached an agreement to pay a one-time incentive bonus to employees upon their planned exit date termination, providing certain performance criteria are met. The salaried employees are being offered the same one-time incentive bonus under the same terms as the union employees. The incentive bonus expense will be recognized ratably over the remaining performance period and is included in the total employee-related cost number above.

A reconciliation of the beginning and ending liability balances showing charges to expense, cash payments and other adjustments for the quarter ended January 31, 2012 is as follows (in thousands):

New Accounting Pronouncements

2. New Accounting Pronouncements

In December 2010, the FASB issued Accounting Standards Update No. 2010-28 (ASU 2010-28) Intangibles—Goodwill and Other (ASC Topic 350) — When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts which amended ASC Topic 350 “Goodwill and Other.” ASU 2010-28 requires an entity with reporting units that have carrying amounts that are zero or negative to assess whether it is more likely than not that the reporting units’ goodwill is impaired. If the entity determines that it is more likely than not that the goodwill of one or more of its reporting units is impaired, the entity is required to perform Step 2 of the goodwill impairment test for those reporting unit(s) and record any resulting impairment as a cumulative-effect adjustment to beginning retained earnings. The provisions of ASU 2010-28 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2010. Early adoption is not permitted. The Company adopted this standard on November 1, 2011. The adoption of ASU 2010-28 did not have a material impact on the Company’s consolidated financial statements.

In May 2011, the FASB issued Accounting Standards Update No. 2011-04 (ASU 2011-04), Fair Value Measurement (ASC Topic 820) Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs. The amended guidance changes the wording used to describe many requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements. Additionally, the amendments clarify the FASB’s intent about the application of existing fair value measurement requirements. The guidance provided in ASU 2011-04 is effective for interim and annual periods beginning after December 15, 2011 (February 1, 2012 for the Company) and is applied prospectively. The Company does not expect the provisions of ASU 2011-04 to have a material effect on its consolidated financial statements.

In June 2011, the FASB issued Accounting Standards Update No. 2011-05 (ASU 2011-05), Presentation of Comprehensive Income. This amendment will require companies to present the components of net income and other comprehensive income either as one continuous statement or as two consecutive statements. It eliminates the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity. The amended guidance, which must be applied retroactively, is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 (November 1, 2012 for the Company), with earlier adoption permitted. ASU 2011-05 impacts presentation only and will have no effect on the Company’s financial condition, results of operations or cash flows. In December 2011, the FASB issued Accounting Standards Update No. 2011-12 (ASU 2011-12), “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05.” ASU 2011-12 deferred the effective date of ASU 2011-05 related to the presentation of reclassifications of items out of accumulated other comprehensive income. All other requirements of ASU 2011-05 were not affected by ASU 2011-12.

In September 2011, the FASB issued Accounting Standards Update No. 2011-08 (ASU 2011-08), Testing Goodwill for Impairment which amends the guidance in ASC 350-20. The amendments in ASU 2011-08 provide entities with the option of performing a qualitative assessment before performing the first step of the two-step impairment test. If entities determine, on the basis of qualitative factors, it is not more likely than not that the fair value of the reporting unit is less than the carrying amount, then performing the two-step impairment test would be unnecessary. However, if an entity concludes otherwise, then it is required to perform the first step of the two-step impairment test by calculating the fair value of the reporting unit and comparing the fair value with the carrying amount of the reporting unit. If the carrying amount of a reporting unit exceeds its fair value, then the entity is required to perform the second step of the goodwill impairment test to measure the amount of the impairment loss, if any. ASU 2011-08 also provides entities with the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to the first step of the two-step impairment test. ASU 2011-08 is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, (November 1, 2012 for the Company), although early adoption is permitted. The provisions of ASU 2011-08 will not have a material effect on its consolidated financial statements.

In December 2011, the FASB issued Accounting Standards Update No. 2011-11 (ASU 2011-11), Disclosures about Offsetting Assets and Liabilities where entities are required to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. This scope would include derivatives, sale and repurchase agreements, and reverse sale and repurchase agreements, and securities borrowing and securities lending arrangements. These disclosures assist users of financial statements in evaluating the effect or potential effect of netting arrangements on a company’s financial position. The Company is required to apply the amendments for annual reporting periods beginning on or after January 1, 2013 (November 1, 2013 for the Company). The Company does not expect the provisions of ASU 2011-11 to have a material impact on its consolidated financial statements.

Quanex Building Products Corporation and its subsidiaries (Quanex or the Company) are managed on a decentralized basis and operate in two business segments: Engineered Products and Aluminum Sheet Products. The Engineered Products segment produces engineered systems, products and components primarily serving the window and door industry, while the Aluminum Sheet Products segment produces mill finished and coated aluminum sheet serving the broader building products markets and secondary markets such as capital goods and transportation. The primary market drivers are residential housing starts and residential remodeling expenditures. Quanex believes it is a technological leader in the production of aluminum sheet products, flexible insulating glass spacer systems, extruded vinyl profiles, thin film solar panel sealants, and precision-formed metal and wood products which primarily serve the North American building products markets. The Company uses low-cost production processes, and engineering and metallurgical expertise to provide customers with specialized products for specific applications.

On December 12, 2007, Quanex Building Products Corporation was incorporated in the state of Delaware as a subsidiary of Quanex Corporation to facilitate the separation of Quanex Corporation’s vehicular products and building products businesses. The separation occurred on April 23, 2008 through the spin-off of Quanex Corporation’s building products business to its shareholders immediately followed by the merger of Quanex Corporation (consisting principally of the vehicular products business and all non-building products related corporate accounts) with a wholly-owned subsidiary of Gerdau S.A. (Gerdau). This is hereafter referred to as the “Separation”. In March 2011, the Company acquired Edgetech I.G., Inc. and its German subsidiary. Headquartered in Cambridge, Ohio, Edgetech has three manufacturing facilities (U.S., U.K. and Germany) that produce and market a full line of insulating glass spacer systems for window and door customers in North America and abroad. In November 2011, management committed to a plan to consolidate its Truseal and U.S. Edgetech facilities. In 2010, management closed its start-up facility in China, and accordingly, the China assets and liabilities, results of operations and cash flows are reported as discontinued operations for all periods presented. Unless otherwise noted, all disclosures in the notes accompanying the consolidated financial statements reflect only continuing operations.

The interim unaudited consolidated financial statements of the Company include all adjustments which, in the opinion of management, are necessary for a fair presentation of the Company’s financial position and results of operations. All such adjustments are of a normal recurring nature. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. The preparation of these financial statements requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying footnotes. Estimates and assumptions about future events and their effects cannot be perceived with certainty. Estimates may change as new events occur, as more experience is acquired, as additional information becomes available and as the Company’s operating environment changes. Actual results could differ from estimates. These statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended October 31, 2011.

Fair Value Measurement of Assets and Liabilities

15. Fair Value Measurement of Assets and Liabilities

The Company’s investments that are measured at fair value on a recurring basis are categorized below using the fair value hierarchy. The fair value hierarchy has three levels based on reliability of inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values obtained from readily available pricing sources for comparable instruments and Level 3 includes fair values requiring measurement without observable market values that would require a high level of judgment to determine fair value. The following table summarizes assets measured on a recurring basis based on the fair value hierarchy:

		September 30,		September 30,
	Quoted Prices in Active Markets for Identical Assets (Level 1)
	January 31, 2012		October 31, 2011
	(In thousands)

Pension plan assets		14,204		14,004
Total	$	90,711	$	94,692

The Company holds Money Market Fund investments that are classified as cash equivalents and pension plan assets measured at fair value based on active market quotations, which represent Level 1 inputs. As of January 31, 2012 and October 31, 2011, the Company did not have any assets or liabilities measured at fair value on a recurring basis in Level 2 or Level 3.

Industry Segment Information

10. Industry Segment Information

Quanex has two reportable segments: Engineered Products and Aluminum Sheet Products. The Engineered Products segment produces systems, finished products and components serving the OEM residential window and door industry, while the Aluminum Sheet Products segment produces mill finished and coated aluminum sheet serving the broader building and construction markets. The primary market drivers of both segments are residential repair and remodel activity (R&R) and new home construction.

The Company measures its inventory at the segment level on a FIFO or weighted-average basis; however at the consolidated Company level, approximately one third of the inventory is measured on a LIFO basis. The LIFO reserve is computed on a consolidated basis as a single pool and is thus treated as a corporate expense. See Note 5 to the financial statements for more information. LIFO inventory adjustments along with corporate office charges and intersegment eliminations are reported as Corporate, Intersegment Eliminations or Other. The Company accounts for intersegment sales and transfers as though the sales or transfers were to third parties, that is, at current market prices. Intersegment sales, related cost of sales, and intercompany profit are eliminated in consolidation at Corporate. Corporate assets primarily include cash and equivalents partially offset by the Company’s consolidated LIFO inventory reserve.

Stock-Based Compensation

Stock-Based Compensation

11. Stock-Based Compensation

Effective with the Separation on April 23, 2008, the Company established the Quanex Building Products Corporation 2008 Omnibus Incentive Plan (the 2008 Plan). The 2008 Plan provides for the granting of stock options, stock appreciation rights, restricted stock awards, restricted stock units (RSUs), performance stock awards, performance unit awards, annual incentive awards, other stock-based awards and cash-based awards. The 2008 Plan is administered by the Compensation and Management Development Committee of the Board of Directors and allows for immediate, graded or cliff vesting options, but options must be exercised no later than ten years from the date of grant. The aggregate number of shares of common stock originally authorized for grant under the 2008 Plan was 2,900,000. At the Company’s annual shareholder meeting in February 2011, the shareholders approved an amendment which increased the aggregate number of shares available for grant under the 2008 Plan by an additional 2,400,000 shares. Any officer, key employee and/or non-employee director of the Company or any of its affiliates is eligible for awards under the 2008 Plan. The initial awards granted under the 2008 Plan were on April 23, 2008; service is the vesting condition.

The Company’s practice is to grant options and restricted stock or RSUs to non-employee directors on October 31st of each year, with an additional grant of options to each director on the date of his or her first anniversary of service. Additionally, the Company’s practice is to grant options, restricted stock and RSUs to employees at the Company’s December board meeting and occasionally to key employees as deemed appropriate at other times during the year. The exercise price of the option awards is equal to the closing market price on the date granted. The Company generally issues shares from treasury stock, if available, to satisfy stock option exercises and grants of restricted stock. If there are no shares in treasury stock, the Company issues additional shares of common stock. The Company has not capitalized any stock-based compensation cost as part of inventory or fixed assets during the three months ended January 31, 2012 and 2011.

Restricted Stock Awards

Under the 2008 Plan, common stock may be awarded to key employees, officers and non-employee directors. The recipient is entitled to all of the rights of a shareholder, except that during the forfeiture period the shares are nontransferable. The awards vest over a specified time period, but typically either immediately vest or cliff vest over a three-year period with service as the vesting condition. Upon issuance of stock under the plan, fair value is measured by the grant-date price of the Company’s shares. This fair value is then expensed over the restricted period with a corresponding increase to additional paid-in-capital. A summary of non-vested restricted stock award changes during the three months ended January 31, 2012 follows:

		September 30,			September 30,
	Shares			Weighted - Average Grant-Date Fair Value Per Share
Non-vested at October 31, 2011		256,390		$	12.67
Granted		83,900			15.08
Vested		(115,790	)		7.82
Non-vested at January 31, 2012		224,500		$	16.08

The weighted-average grant-date fair value of restricted stock granted during the three months ended January 31, 2012 and 2011 was $15.08 and $16.90 per share, respectively. The total fair value of restricted stock vested during the three months ended January 31, 2012 was $0.9 million. There were no restricted stock shares that vested during the three months ended January 31, 2011. Total unrecognized compensation cost related to unamortized restricted stock awards was $2.2 million as of January 31, 2012. This cost is expected to be recognized over a weighted-average period of 2.2 years.

Stock Options

As described in the Company’s Annual Report on Form 10-K for the fiscal year ended October 31, 2011, the Company uses the Black-Scholes-Merton option-pricing model to estimate the fair value of its stock options. The fair value of each option was estimated on the date of grant. The following is a summary of valuation assumptions and resulting grant-date fair values for grants during the following periods:

		September 30,			September 30,
	Three Months Ended January 31,
	2012			2011
Weighted-average expected volatility		54.0	%		53.0	%
Expected term (in years)		4.9-5.1			4.9-5.1
Risk-free interest rate		1.0	%		1.6	%
Expected dividend yield over expected term		1.0	%		1.0	%
Weighted-average grant-date fair value per share	$	6.49		$	7.30

Below is a table summarizing the stock option shares activity for the 2008 Plan since October 31, 2011:

		September 30,			September 30,		September 30,		September 30,
	Shares			Weighted- Average Exercise Price Per Share		Weighted- Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value (000s)
Outstanding at October 31, 2011		2,137,436		$	14.08
Granted		454,300			15.08
Exercised		(1,834	)		9.79
Cancelled/Expired		(2,666	)		13.27
Outstanding at January 31, 2012		2,587,236			14.26		7.5	$	6,120
Vested or expected to vest at January 31, 2012		2,518,386			14.19		7.5	$	6,086
Exercisable at January 31, 2012		1,726,394		$	13.33		6.6	$	5,482

The total intrinsic value of options (the amount by which the market price of the stock on the date of exercise exceeded the exercise price of the option) exercised during the three months ended January 31, 2012 and 2011 was $12 thousand and $0.2 million, respectively. The total fair value of shares vested during the three months ended January 31, 2012 and 2011 was $2.1 million and $1.3 million, respectively. Total unrecognized compensation cost related to stock options granted under the 2008 Plan was $4.6 million as of January 31, 2012. This cost is expected to be recognized over a weighted-average period of 1.9 years.

Restricted Stock Units

RSUs vest over a specified time period, but typically either immediately vest or cliff vest over a three-year period with service as the vesting condition. RSUs are not considered to be outstanding shares of common stock and do not have voting rights. Holders of RSUs receive cash for an equivalent amount of cash dividends paid on the underlying common stock. Upon the earlier of the date the director ceases to be a board member or a change of control or upon vesting for the employee grants, each RSU is payable in cash in an amount equal to the market value of one share of the Company’s common stock. Accordingly, the RSU liability will be adjusted to fair market value at each reporting date. The Company granted 137,500 and 0 RSU awards, respectively, during the quarters ended January 31, 2012 and 2011. The fair market value per share of the outstanding awards was $16.43 and $19.49 as of January 31, 2012 and 2011, respectively. The aggregate amount charged to expense with respect to these awards was $0.2 million and $0.1 million for the quarters ended January 31, 2012 and 2011, respectively. The number of RSU awards outstanding as of January 31, 2012 and October 31, 2011 was 193,910 and 56,410, respectively.

Total	$	64,150	$	55,842

Fixed costs related to excess manufacturing capacity, if any, have been expensed in the period, and therefore, are not capitalized into inventory. The values of inventories are based on the following accounting methods:

LIFO	$	21,215	$	18,782
FIFO		42,935		37,060
Total	$	64,150	$	55,842

An actual valuation of inventory under the last in, first out (LIFO) method can be made only at the end of each year based on the inventory costs and levels at that time. Accordingly, interim LIFO calculations must be based on management’s estimates of expected year-end inventory costs and levels. Because these are subject to many factors beyond management’s control, interim results are subject to the final year-end LIFO inventory valuation which could significantly differ from interim estimates. To estimate the effect of LIFO on interim periods, the Company performs a projection of the year-end LIFO reserve and considers expected year-end inventory pricing and expected inventory levels. Depending on this projection, the Company may record an interim allocation of the projected year-end LIFO calculation. This projection resulted in zero interim LIFO allocation (reported in Cost of sales) for the three months ended January 31, 2012. With respect to inventories valued using the LIFO method, replacement cost exceeded the LIFO value by approximately $12.3 million as of January 31, 2012 and October 31, 2011, respectively.

Stock Repurchase Program and Treasury Stock

16. Stock Repurchase Program and Treasury Stock

On May 27, 2010, the Board of Directors approved a stock repurchase program of 1.0 million shares, and on August 25, 2011, the Board of Directors authorized an additional 1.0 million shares to this program. The objectives of this program are to manage the dilution created by shares issued under stock-based compensation plans and to repurchase shares opportunistically. The Company records treasury stock purchases under the cost method whereby the entire cost of the acquired stock is recorded as treasury stock. The Company uses a moving-average method on the subsequent reissuance of shares, and any resulting proceeds in excess of cost are credited to additional paid in capital while any deficiency is charged to retained earnings.

As of October 31, 2011, the number of shares in treasury stock was 1,035,288. During the three months ended January 31, 2012, the Company purchased 94,337 shares at a cost of $1.3 million partially offset by shares issued for stock option exercises and restricted stock grants for a net increase to the number of shares in treasury stock to 1,043,891 as of January 31, 2012. Since inception of the program, Quanex has purchased 1,094,337 shares through January 31, 2012. The remaining shares authorized for repurchase in the program was 905,663 as of January 31, 2012.

Income Taxes

Income Taxes

12. Income Taxes

The provision for income taxes is determined by applying an estimated annual effective income tax rate to income from continuing operations before income taxes. The rate is based on the most recent annualized forecast of pretax income, permanent book versus tax differences and tax credits. The Company’s estimated annual effective tax rate for the three months ended January 31, 2012 is 39.8% compared to the estimated annual effective tax rate of 38.5% for the three months ended January 31, 2011. The increase is attributable in part to the mix of domestic and foreign results which were not present in the first quarter of 2011 results.

Prepaid and other current assets on the Consolidated Balance Sheets include an income tax receivable of $0.2 million as of January 31, 2012 and October 31, 2011.

The Company’s unrecognized tax benefit (UTB) is related to the Separation and state tax items regarding the interpretations of tax laws and regulations. The total UTB as of January 31, 2012 is $19.1 million. Of this, $8.5 million is recorded in Liability for uncertain tax positions and $10.6 million is recorded in Deferred income taxes (non-current assets) on the Consolidated Balance Sheets. The UTB includes $17.8 million for which the disallowance of such items would not affect the annual effective tax rate.

Judgment is required in assessing the future tax consequences of events that have been recognized in the Company’s financial statements or income tax returns. The final outcome of the future tax consequences of legal proceedings, if any, as well as the outcome of competent authority proceedings, changes in regulatory tax laws, or interpretation of those tax laws could impact the Company’s financial statements. The Company is subject to the effects of these matters occurring in various jurisdictions. The Company believes that it is reasonably possible that a decrease of approximately $3.5 million in the UTB may be recognized within the next twelve months as a result of a lapse in the statute of limitations.

The Company’s $270.0 million Senior Unsecured Revolving Credit Facility (the Credit Facility) was executed on April 23, 2008. The Credit Facility has a five-year term and is unsecured. The Credit Facility expires April 23, 2013 and provides for up to $50.0 million for standby letters of credit, limited to the undrawn amount available under the Credit Facility. Borrowings under the Credit Facility bear interest at a spread above LIBOR based on a combined leverage and ratings grid. Proceeds from the Credit Facility may be used to provide availability for acquisitions, working capital, capital expenditures and general corporate purposes.

Under the Credit Facility, the Company is obligated to comply with certain financial covenants requiring the Company to maintain a Consolidated Leverage Ratio of no more than 3.25 to 1 and a Consolidated Interest Coverage Ratio of no less than 3.00 to 1. As defined by the Credit Facility’s indenture, the Consolidated Leverage Ratio is the ratio of consolidated indebtedness as of such date to consolidated EBITDA for the previous four fiscal quarters; and the Consolidated Interest Coverage Ratio is the ratio of consolidated EBITDA to consolidated interest expense for the previous four consecutive fiscal quarters. EBITDA is defined by the indenture to include proforma EBITDA of acquisitions and to exclude certain items like non-cash charges. Additionally, the Credit Facility contains certain limitations on additional indebtedness, asset or equity sales, and acquisitions. Dividends and other distributions are permitted so long as after giving effect to such dividend or stock repurchase, there is no event of default.

As of January 31, 2012, the Company had no borrowings under the Credit Facility, and the Company was in compliance with all Credit Facility financial covenants. The availability under the Credit Facility is a function of both the facility amount utilized and meeting covenant requirements. Although there were no borrowings on the Credit Facility and only $5.6 million of outstanding letters of credit under the Credit Facility, the aggregate availability under the Credit Facility was limited by the Consolidated Leverage Ratio resulting in an availability of $173.1 million at January 31, 2012.

Earnings and Dividends Per Share

6. Earnings and Dividends Per Share

Earnings Per Share

Fiscal 2012 and 2011 basic and diluted earnings per share from continuing operations are identical as the Company reported a loss from continuing operations. The computation of diluted earnings per share excludes outstanding options and other common stock equivalents in periods where inclusion of such potential common stock instruments would be anti-dilutive in the periods presented. When income from continuing operations is a loss, all potential dilutive instruments are excluded from the computation of diluted earnings per share as they would be anti-dilutive. Accordingly, for the three months ended January 31, 2012, 0.1 million of restricted stock and 0.3 million of common stock equivalents were excluded from the computation of diluted earnings per share as the Company had a loss from continuing operations. Accordingly, for the three months ended January 31, 2011, 0.2 million of restricted stock and 0.4 million of common stock equivalents were excluded from the computation of diluted earnings per share as the Company had a loss from continuing operations.

For the three months ended January 31, 2012 and 2011, the Company had 1.3 million and 0.5 million, respectively, of securities that are potentially dilutive in future earnings per share calculations. Such dilution will be dependent on the excess of the market price of the Company’s stock over the exercise price and other components of the treasury stock method.

Dividends Per Share

During the three months ended January 31, 2012 and 2011, the Company paid $0.04 cash dividend per common share.

Comprehensive income comprises net income and all other non-owner changes in equity, including foreign currency translation, pension related adjustments and realized and unrealized gains and losses on derivatives, if any. Comprehensive income for the three months ended January 31, 2012 and 2011 was as follows:

The 2012 foreign currency translation activity is primarily associated with Edgetech, acquired by the Company on March 31, 2011. As a result of this acquisition, Quanex has operations in Germany and the United Kingdom whose functional currency is the Euro and the British Pound Sterling, respectively.

Retirement Plans

Retirement Plans

9. Retirement Plans

The Company has a number of retirement plans covering substantially all employees. The Company provides both defined benefit and defined contribution plans. In general, the plant or location of employment determines an employee’s coverage for retirement benefits. Effective with the respective acquisition dates in the second fiscal quarter of 2011, the Edgetech employees were eligible to participate in the Company’s retirement plans.

Pension Plan

The Company has a non-contributory, single employer defined benefit pension plan that covers substantially all non-union employees. Effective January 1, 2007, the Company amended this defined benefit pension plan to include a new cash balance formula for all new salaried employees hired on or after January 1, 2007 and for any non-union employees who were not participating in a defined benefit plan prior to January 1, 2007. All new salaried employees are eligible to receive credits equivalent to 4% of their annual eligible wages, while some of the employees at the time of the plan amendment were “grandfathered” and are eligible to receive credits ranging up to 6.5% based upon a percentage they received in the defined contribution plan prior to the amendment of the pension plan. Additionally, every year the participants will receive an interest related credit on their respective balance equivalent to the prevailing 30-year Treasury rate. Benefits for participants in this plan prior to January 1, 2007 continue to be based on a more traditional formula for retirement benefits, where the plan pays benefits to employees upon retirement using a formula based upon years of service and pensionable compensation prior to retirement. Of the Company’s participants, 99% are under the cash balance formula.

The components of net periodic pension cost are as follows:

		September 30,			September 30,
	Three Months Ended January 31,
	2012			2011
	(In thousands)
Net periodic benefit cost:
Service cost	$	980		$	937
Interest cost		204			200
Expected return on plan assets		(277	)		(258	)
Amortization of net loss		50			22
Net periodic benefit cost	$	957		$	901

The increase in net pension cost from 2011 to 2012 is primarily attributable to an increase in participants from the Edgetech acquisition. The Company’s pension funding policy generally has been to make the minimum annual contributions required by applicable regulations while considering targeted funded percentages. In fiscal 2010, the Company decided to modify its funding strategy and accelerate contributions to target a 100% funding threshold. Additionally, the Company will consider funding fiscal year requirements early in the fiscal year to potentially maximize returns on assets. The Company made no contributions to its defined benefit plan during the three months ended January 31, 2012. In February 2012, the Company contributed $4.2 million to the plan. Future contributions are dependent on many variables, including the variability of the market value of the assets as compared to the obligation and other market or regulatory conditions. In addition, the Company takes into consideration its business investment opportunities and resulting cash requirements. Accordingly, actual funding may differ greatly from current estimates.

The Company’s estimated obligations for warranty are accrued concurrently with the revenue recognized. The Company makes provisions for its warranty obligations based upon historical experience incurred for such obligations adjusted, as necessary, for current conditions and factors. Due to the significant uncertainties and judgments involved in estimating the Company’s warranty obligations, including changing product designs, variance in customer installation process and future claims experience varying from historical claims experience, the ultimate amount incurred for warranty costs could change in the near and long-term from the current estimate.

On March 31, 2011, Quanex completed its acquisition of Edgetech I.G., Inc., an Ohio corporation (“Edgetech I.G.”), the United Kingdom division of Edgetech (“Edgetech UK”), and Edgetech Europe GmbH, a German company (“Edgetech Germany” and together with Edgetech I.G. and Edgetech UK, “Edgetech”). Headquartered in Cambridge, Ohio, Edgetech has three manufacturing facilities located in the United States, the United Kingdom and Germany that produce a full line of warm-edge, dual seal insulating glass spacer systems for window and door customers in North America and abroad. Edgetech’s products separate and seal double and triple glass within a window and act as a thermal barrier that enhances the window’s energy efficiency. Edgetech has been integrated into the Engineered Products segment.

As consideration for the acquisition, Quanex paid $104.4 million in cash, net of $0.8 million of cash acquired. Of the cash paid, $7.0 million was placed into an escrow fund to satisfy certain indemnity obligations under the merger agreement. Additionally, Quanex is responsible for the tax liability resulting from the pre-closing reorganization of Lauren and its subsidiaries limited to $3.5 million, of which $3.0 million has been paid. The Edgetech acquisition was accounted for as a business combination using the acquisition method of accounting under which the total purchase price consideration is allocated to assets and liabilities assumed based upon their fair values. The purchase price allocation resulted in goodwill of $44.6 million, which is not deductible for income tax purposes. Any transaction-related costs in connection with the Edgetech acquisition were expensed as occurred within Selling, general and administrative expense in its Consolidated Statement of Income.

The following table provides consolidated results of operations for the three months ended January 31, 2012 compared to unaudited pro forma consolidated results of operations for the combined entity for the three months ended January 31, 2011 as if Edgetech had been acquired as of November 1, 2009.

The unaudited pro forma consolidated results of operations were prepared using the acquisition method of accounting and are based on the historical financial information of the Company and Edgetech. The unaudited pro forma financial information does not purport to reflect the results the combined company may achieve in future periods or the results that would have been obtained had Quanex acquired Edgetech on the first day of its fiscal 2010 period. The unaudited pro forma financial information does not include any operating efficiencies or cost savings that may be achieved or any integration expenses. Additionally, the historical Edgetech financial information has not been adjusted to remove expenses that will cease under Quanex’s ownership, such as the prior parent company allocation, or to add incremental anticipated stand-alone expenses going forward. Generally, the pro forma financial information reflects the allocation of the purchase price to the appropriate assets and liabilities based upon their fair values, and related changes in depreciation and amortization expense. Accordingly, such amounts are not necessarily indicative of the results that would have occurred if the acquisition had occurred on the dates indicated or that may result in the future. The unaudited pro forma information reflects primarily the following unaudited pro forma adjustments for the three months ended January 31, 2011:

• Historical pre-acquisition results of operations for Edgetech for the three months ended January 31, 2011;

• Amortization expense related to the fair value of identifiable intangible assets acquired;

• Additional depreciation expense related to the fair value adjustment to property, plant and equipment acquired;

• Additional facility rental expense;

• Reduction of expense of $1.1 million in the three months ended January 31, 2011 to remove the transaction-related costs incurred;

• The Edgetech historical results and all of the above adjustments were adjusted for the applicable tax impact.

13. Contingencies

Environmental

Quanex is subject to extensive laws and regulations concerning the discharge of materials into the environment and the remediation of chemical contamination. To satisfy such requirements, Quanex must make capital and other expenditures on an ongoing basis. The Company accrues its best estimates of its remediation obligations and adjusts such accruals as further information and circumstances develop. Those estimates may change substantially depending on information about the nature and extent of contamination, appropriate remediation technologies, and regulatory approvals. In accruing for environmental remediation liabilities, costs of future expenditures are not discounted to their present value, unless the amount and timing of the expenditures are fixed or reliably determinable. When environmental laws might be deemed to impose joint and several liability for the costs of responding to contamination, the Company accrues its allocable share of liability taking into account the number of parties participating, their ability to pay their shares, the volumes and nature of the wastes involved, the nature of anticipated response actions, and the nature of the Company’s alleged connections. The cost of environmental matters has not had a material adverse effect on Quanex’s operations or financial condition in the past, and management is not currently aware of any conditions that it believes are likely to have a material adverse effect on Quanex’s operations, financial condition or cash flows.

Total environmental reserves and corresponding recovery for the Company as of January 31, 2012 and October 31, 2011 were as follows:

		September 30,		September 30,
	January 31, 2012		October 31, 2011
	(In thousands)
Current1	$	1,965	$	1,965
Non-current		11,058		11,221
Total environmental reserves	$	13,023	$	13,186
Receivable for recovery of remediation costs2	$	11,860	$	12,304

²  Reported in Accounts receivable and Other assets on the Consolidated Balance Sheets.

Currently, the Company’s ongoing remediation activities are at one of its subsidiaries, Nichols Aluminum-Alabama, LLC (NAA). NAA operates a plant in Decatur, Alabama that is subject to an Alabama Hazardous Wastes Management and Minimization Act Post-Closure Permit. Among other things, the permit requires NAA to remediate, as directed by the state, historical environmental releases of wastes and waste constituents. Consistent with the permit, NAA has undertaken various studies of site conditions and, during the first quarter of 2006, started a phased program to treat in-place free product petroleum that had been released underneath the plant. During the second quarter 2010, NAA submitted to the state the first component of its proposed workplan for implementing a site-wide remedy. The full workplan was submitted to the state during the third quarter 2010, revised during the second quarter 2011 to reflect both additional sampling data and responses to state comments, and revised again in the fourth quarter 2011 in response to another round of state comments. Based on those plans, which remain subject to further comment, revision, and state approval, the Company’s remediation reserve at NAA’s Decatur plant is $12.8 million as of January 31, 2012. Approximately $1.3 million of the January 31, 2012 reserve represents administrative costs; the balance of $11.5 million represents estimated costs for investigation, studies, cleanup, and treatment. The reserve has not been discounted. NAA was acquired through a stock purchase in which the sellers agreed to indemnify Quanex and NAA for identified environmental matters related to the business and based on conditions initially created or events initially occurring prior to the acquisition. Environmental conditions are presumed to relate to the period prior to the acquisition unless proved to relate to releases occurring entirely after closing. The limit on indemnification is $21.5 million excluding legal fees. While the Company’s current estimates indicate it will not reach this limit, changing circumstances could result in additional costs or expense that are not foreseen at this time. In accordance with the indemnification, the indemnitors paid the first $1.5 million of response costs and have been paying 90% of ongoing costs. Based on its experience to date, its estimated cleanup costs going forward, and costs incurred to date as of January 31, 2012, the Company expects to recover from the sellers’ shareholders an additional $11.9 million which has not been discounted. Of that, $11.5 million is recorded in Other assets on the Consolidated Balance Sheets, and the balance is reflected in Accounts receivable on the Consolidated Balance Sheets. The undiscounted recovery from indemnitors as of October 31, 2011 was $12.3 million.

The Company’s final remediation costs and the timing of those expenditures will depend upon such factors as the nature and extent of contamination, the cleanup technologies employed, the effectiveness of the cleanup measures that are employed, and regulatory concurrences. While actual remediation costs, therefore, may be more or less than amounts accrued, the Company believes it has established adequate reserves for all probable and reasonably estimable remediation liabilities. It is not possible at this point to reasonably estimate the amount of any obligation for remediation in excess of current accruals because of uncertainties as to the extent of environmental impact, cleanup technologies, and concurrence of governmental authorities. The Company currently expects to pay the accrued remediation reserve through at least fiscal 2034, although some of the same factors discussed earlier could accelerate or extend the timing.

Other

From time to time, the Company and its subsidiaries are involved in various litigation matters arising in the ordinary course of their business. Although the ultimate resolution and impact of such litigation on the Company is not presently determinable, the Company’s management believes that the eventual outcome of such litigation will not have a material adverse effect on the overall financial condition, results of operations or cash flows of the Company.
