QUANEX BUILDING PRODUCTS CORPORATION

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Nature of Operations and Basis of Presentation

Quanex Building Products Corporation manufactures components primarily for the window and door (fenestration) industry, which include (1) energy-efficient flexible insulating glass spacers, (2) extruded vinyl profiles, (3) window and door screens, and (4) precision-formed metal and wood products for original equipment manufacturers (OEMs), as well as certain non-fenestration components, which include solar panel sealants, wood flooring and trim moldings. Quanex Building Products Corporation serves a primary customer base in North America and also serves customers in international markets through operating plants in the United Kingdom and Germany, as well as through sales and marketing efforts in other countries.

Unless the context indicates otherwise, references to "Quanex", the "Company", "we", "us" and "our" refer to the consolidated business operations of Quanex Building Products Corporation and its subsidiaries.

The accompanying interim condensed consolidated financial statements include the accounts of Quanex Building Products Corporation. All intercompany accounts and transactions have been eliminated in consolidation. These financial statements have been prepared by us, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. The consolidated balance sheet as of October 31, 2014 was derived from audited financial information, but does not include all disclosures required by U.S. GAAP. The accompanying financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto, included in our Annual Report on Form 10-K for the fiscal year ended October 31, 2014. In our opinion, the accompanying financial statements contain all adjustments (which consist of normal recurring adjustments, except as disclosed herein) necessary to fairly present our financial position, results of operations and cash flows for the interim periods. The results of operations for the periods presented are not necessarily indicative of the results to be expected for the full year or for any future periods.

In preparing financial statements, we make informed judgments and estimates that affect the reported amounts of assets and liabilities as of the date of the financial statements and affect the reported amounts of revenues and expenses during the reporting period. We review our estimates on an on-going basis, including those related to impairment of long lived assets and goodwill, contingencies and income taxes. Changes in facts and circumstances may result in revised estimates and actual results may differ from these estimates.

Discontinued Operations

Prior to April 1, 2014, we had two reportable business segments: (1) Engineered Products and (2) Aluminum Sheet Products. On April 1, 2014, we sold our interest in a limited liability company which held the assets of the Nichols Aluminum business (Nichols), the sole operating segment included in our Aluminum Sheet Products reportable segment, to Aleris International, Inc.

(Aleris), a privately held Delaware corporation which provides aluminum rolled products and extrusions, aluminum recycling and specification aluminum alloy production. We received gross proceeds of $110.0 million, which was reduced to $107.4 million, reflecting a net working capital adjustment of $2.6 million that we paid in June 2014, resulting in a net gain on the transaction of $24.1 million, net of related taxes of $15.1 million.

Nichols represented a significant portion of our assets and operations. We accounted for this sale as a discontinued operation. We revised our financial statements and removed the results of operations of Nichols from net income (loss) from continuing operations, and presented separately as income (loss) from discontinued operations, net of taxes, for each of the accompanying condensed consolidated statements of income (loss). Unless noted otherwise, the notes to the consolidated financial statements pertain to our continuing operations.

For cash flow statement presentation, the sources and uses of cash for Nichols are presented as operating, investing and financing cash flows, as applicable, combined with such cash flows for continuing operations for the period from November 1, 2013 to April 1, 2014, as permitted by U.S. GAAP.

We have historically purchased rolled aluminum product from Nichols. We expect to continue to purchase aluminum from Nichols in the normal course of business. We considered whether these aluminum purchases and the services provided under a transition services agreement for the period from April 1, 2014 to May 31, 2014 constituted significant continuing involvement with Nichols. Since these purchases were in the normal course of business and the services provided were for a relatively short period and are customary for similar transactions, we determined that this involvement was not deemed significant and did not preclude accounting for the transaction as a discontinued operation. Our purchases of aluminum product from Nichols for the three- and six-month periods ended April 30, 2015 and 2014 were $1.6 million and $6.2 million, respectively, and $3.3 million and $6.8 million, respectively.

QUANEX BUILDING PRODUCTS CORPORATION

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

In November 2013, Nichols experienced a fire at its Decatur, Alabama facility, which damaged a cold mill used to roll aluminum sheet to a desired thickness. The loss was insured, subject to a $0.5 million deductible. We capitalized $6.5 million to rebuild the asset, which was returned to service as of March 31, 2014. We incurred costs of $2.3 million associated with this loss, including an impairment of $0.5 million related to retirement of the asset, moving costs, outside service costs, clean-up and the deductible. To date, we have received insurance proceeds of $5.3 million. We have reduced our estimate of total insurance proceeds expected related to this loss to approximately $6.3 million, resulting in an expected gain on involuntary conversion of $3.9 million of which we have recognized $2.9 million. We estimate the remaining pretax gain on involuntary conversion at $1.0 million and that this gain will be recognized during fiscal 2015, when and to the extent that insurance proceeds are received, which will result in an increase in income from discontinued operations, net of tax.

Income from discontinued operations for the six months ended April 30, 2015 reflects the receipt of insurance proceeds of $0.5 million, less approximately $0.5 million associated with a health insurance claim amount reimbursable to the stop-loss insurance provider.

The following table summarizes the operating results for Nichols, which was sold on April 1, 2014, included in the three- and six-month periods ended April 30, 2014:

	Three Months Ended			Six Months Ended
	April 30, 2014
	(In thousands, except per share amounts)
Net sales	$	63,306		$	142,797

Basic income per common share	$	0.59		$	0.53
Diluted income per common share	$	0.58		$	0.52

Product Sales

We produce a wide variety of products that are used in the fenestration industry, including: window and door systems design, engineering and fabrication; accessory trim profiles with real wood veneers and wood grain laminate finishes; window spacer systems; extruded vinyl products; metal fabrication; and astragals, thresholds and screens. In addition, we produce certain non-fenestration products, including: wood and aluminum grilles, flooring and trim moldings, solar edge tape and other products. Historically, we have presented product sales information at the reportable segment level, and we attribute our net sales based on the location of the customer. We have four operating segments that are aggregated into one reportable segment, which includes this breadth of product offerings across the fenestration and non-fenestration spectrum, but for which there are common economic and other characteristics that meet the criteria for aggregation.

ASC Topic 280-10-50, “Segment Reporting” (ASC 280) permits aggregation of operating segments based on factors including, but not limited to: (1) similar nature of products serving the building products industry, primarily the fenestration business; (2) similar production processes, although there are some differences in the amount of automation amongst operating plants; (3) similar types or classes of customers, namely the primary original equipment manufacturers (OEMs) in the window and door industry; (4) similar distribution methods for product delivery, although the extent of the use of third-party distributors will vary amongst the businesses; (5) similar regulatory environment; and (6) converging long-term economic similarities.

The following table summarizes our product sales for the three- and six-month periods ended April 30, 2015 and 2014 into general groupings to provide additional information to our shareholders.

2. Acquisitions

On December 31, 2013, we acquired certain vinyl extrusion assets of Atrium Windows and Doors, Inc. (Atrium) at a facility in Greenville, Texas, for $5.2 million in cash (Greenville). We accounted for this transaction as a business combination resulting in an insignificant gain on the purchase. We entered into a supply agreement with Atrium related to the products produced at Greenville. We believe this acquisition expanded our vinyl extrusion capacity and positioned us with a platform from which to better serve our customers in the southern United States.

The purchase price has been allocated to the fair value of the assets acquired and liabilities assumed, as indicated in the table below.

	As of Date of Opening Balance Sheet
	(In thousands)
Net assets acquired:
Inventories	$	161
Prepaid and other current assets	145
Property, plant and equipment	4,695
Intangible assets	290
Deferred income tax liability	(50		)
Net assets acquired	$	5,241
Consideration:
Cash, net of cash and cash equivalents acquired	$	5,161
Gain recognized on bargain purchase	$	80

We used recognized valuation techniques to determine the fair value of the assets and liabilities, including the income approach for customer relationships, with a discount rate that reflects the risk of the expected future cash flows. The gain on bargain purchase of approximately $0.1 million is included in "Other, net" on our condensed consolidated statement of income (loss) for the six months ended April 30, 2014.

Pro forma results of operations were omitted because this acquisition was not deemed to be material to our results of operations for the six months ended April 30, 2014.

3. Inventories

Inventories consisted of the following at April 30, 2015 and October 31, 2014:

Fixed costs related to excess manufacturing capacity, if any, have been expensed in the period they were incurred and, therefore, are not capitalized into inventory.

Our inventories at April 30, 2015 and October 31, 2014 were valued using the following costing methods:

During interim periods, we estimate a LIFO reserve based on our expectations of year-end inventory levels and costs. If our calculations indicate that an adjustment at year-end will be required, we record a proportionate share of this amount during the period. At year-end, we calculate the actual LIFO reserve and record an adjustment for the difference between the annual calculation and any estimates recognized during the interim periods.  Because the interim projections are subject to many factors beyond our control, the results could differ significantly from the year-end LIFO calculation. We recorded no interim LIFO reserve adjustment for the three- and six-month periods ended April 30, 2015 and 2014.     

For inventories valued under the LIFO method, replacement cost exceeded the LIFO value by approximately $1.4 million at April 30, 2015 and October 31, 2014.

4. Goodwill and Intangible Assets

Goodwill

The change in the carrying amount of goodwill for the six months ended April 30, 2015 was as follows:

	Six Months Ended
	April 30, 2015
	(In thousands)
Beginning balance as of November 1, 2014	70,546
Foreign currency translation adjustment	(1,758		)
Balance as of the end of the period	$	68,788

During the fourth quarter of 2014, we evaluated our goodwill balances for indicators of impairment and performed an annual goodwill impairment test to determine the recoverability of these assets. Three of our reporting units had goodwill at October 31, 2014 which totaled $55.2 million, $12.6 million and $2.8 million. We determined that our goodwill was not impaired and there have been no triggering events to indicate impairment during the six months ended April 30, 2015, so no additional testing was deemed necessary.

Identifiable Intangible Assets

Amortizable intangible assets consisted of the following as of April 30, 2015 and October 31, 2014:

	April 30, 2015				October 31, 2014
	Gross Carrying Amount		Accumulated Amortization		Gross Carrying Amount		Accumulated Amortization

Total	$	124,441	$	58,793	$	124,441	$	54,291

We do not estimate a residual value associated with these intangible assets. Included in intangible assets as of April 30, 2015 were customer relationships of $0.2 million associated with the Greenville acquisition. These assets have estimated remaining useful lives of four years. See Note 2, "Acquisitions", included herewith.

For the three- and six-month periods ended April 30, 2015 and 2014, we had aggregate amortization expense of $2.2 million and $4.5 million, respectively, and $2.3 million and $4.6 million, respectively.

Estimated remaining amortization expense, assuming current intangible balances and no new acquisitions, for each of the fiscal years ending October 31, was as follows (in thousands):

	Estimated Amortization Expense
2015 (remaining six months)	$	4,612
2016	8,713
2017	8,607
2018	8,360
2019	7,571
Thereafter	27,785
Total	$	65,648

5. Debt and Capital Lease Obligations

Debt consisted of the following at April 30, 2015 and October 31, 2014:

	April 30, 2015		October 31, 2014
	(In thousands)
Revolving Credit Facility	$	—	$	—

Total debt	634		785
Less: Current maturities of long-term debt	179		199
Long-term debt	$	455	$	586

On January 28, 2013, we entered into a Senior Unsecured Revolving Credit Facility (the Credit Facility) that has a five-year term and permits aggregate borrowings at any time of up to $150.0 million, with a letter of credit sub-facility, a swing line sub-facility and a multi-currency sub-facility. Borrowings denominated in United States dollars bear interest at a spread above the London Interbank Borrowing Rate (LIBOR) or a base rate derived from the prime rate. Foreign denominated borrowings bear interest at a spread above the LIBOR applicable to such currencies. Subject to customary conditions, we may request that the

QUANEX BUILDING PRODUCTS CORPORATION

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

aggregate commitments under the Credit Facility be increased by up to $100.0 million, with total commitments not to exceed $250.0 million.

The Credit Facility requires us to comply with certain financial covenants, the terms of which are defined therein. Specifically, we must not permit, on a quarterly basis, our ratio of consolidated EBITDA to consolidated interest expense as defined (Minimum Interest Coverage Ratio), to fall below 3.00:1 or our ratio of consolidated funded debt to consolidated EBITDA, as defined (Maximum Consolidated Leverage Ratio), to exceed 3.25:1. The Maximum Consolidated Leverage 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 pro forma EBITDA of acquisitions and to exclude certain items such as goodwill and intangible asset impairments and certain other non-cash charges and non-recurring items. Subject to our compliance with the covenant requirements, the amount available under the Credit Facility is a function of: (1) our trailing twelve-month EBITDA; (2) the Minimum Interest Coverage Ratio and Maximum Consolidated Leverage Ratio allowed under the Credit Facility; and (3) the aggregate amount of our outstanding debt and letters of credit. As of April 30, 2015, we were in compliance with the financial covenants set forth in the Credit Facility.

As of April 30, 2015, the amount available to us for use under the Credit Facility was $143.4 million and we had outstanding letters of credit of $5.9 million. For the six-month period ended April 30, 2015, we did not borrow any amounts under the Credit Facility, and thus had no outstanding borrowings at April 30, 2015. Our current borrowing rate under the Credit Facility was 3.25% and 1.20% for the swing-line sub facility and the revolver, respectively, at April 30, 2015. As of October 31, 2014, the amount available to us for use under the Credit Facility was $140.7 million and we had outstanding letters of credit of $6.1 million. Our borrowing rate under the Credit Facility was 3.25% and 1.20% for the swing-line sub facility and the revolver, respectively, at October 31, 2014.

6. Retirement Plans

Pension Plan

Our non-contributory, single employer defined benefit pension plan covers a majority of our employees. Employees of acquired companies may be covered after a transitional period. The net periodic pension cost for this plan for the three- and six-month periods ended April 30, 2015 and 2014 was as follows:

	Three Months Ended						Six Months Ended
	April 30,						April 30,
	2015			2014			2015			2014
	(In thousands)
Service cost	$	802		$	737		$	1,683		$	1,657
Interest cost	257			269			510			532
Expected return on plan assets	(443		)	(438		)	(904		)	(861		)
Amortization of net loss	40			—			79			—
Net periodic benefit cost	$	656		$	568		$	1,368		$	1,328

During 2014, we contributed approximately $4.1 million to fund our plan, and we expect to make a contribution to our plan in September 2015.

Other Plans

We also have a supplemental benefit plan covering certain executive officers and a non-qualified deferred compensation plan covering members of the Board of Directors and certain key employees. As of April 30, 2015 and October 31, 2014, our liability under the supplemental benefit plan was approximately $1.8 million and $1.9 million, respectively, and under the deferred compensation plan was approximately $3.4 million for both periods. In January 2014, we paid $3.3 million related to the deferred compensation plan as a result of the separation of our former chief executive officer in July 2013. We record the current portion of liabilities under these plans under the caption "Accrued Liabilities," and the long-term portion under the caption "Other Liabilities" in the accompanying balance sheets.

7. Warranty Obligations

We accrue warranty obligations as we recognize revenue associated with certain products. We make provisions for our warranty obligations based upon historical experience of costs incurred for such obligations adjusted, as necessary, for current

QUANEX BUILDING PRODUCTS CORPORATION

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

conditions and factors. During January 2014, we reduced our warranty accrual by $2.8 million for certain products associated with our insulating glass business that were discontinued in a prior year and for which claim activity for a particular customer had ceased. There are significant uncertainties and judgments involved in estimating our warranty obligations, including changing product designs, differences in customer installation processes and future claims experience which may vary from historical claims experience. Therefore, the ultimate amount we incur as warranty costs in the near and long-term may not be consistent with our current estimate.

A reconciliation of the activity related to our accrued warranty, including both the current and long-term portions (reported in accrued liabilities and other liabilities, respectively, on the accompanying condensed consolidated balance sheet) follows:

	Six Months Ended
	April 30, 2015
	(In thousands)
Beginning balance as of November 1, 2014	$	671
Provision for warranty expense	263
Change in accrual for preexisting warranties	99
Warranty costs paid	(124		)
Total accrued warranty as of the end of the period	$	909
Less: Current portion of accrued warranty	678
Long-term portion of accrued warranty	$	231

The increase in the warranty provision during the six months ended April 30, 2015 was primarily attributable to a specific claim related to our vinyl extrusion products stemming from a change in formulation.

8. Income Taxes

To determine our income tax expense for interim periods, consistent with accounting standards, we apply the estimated annual effective income tax rate to year-to-date results. Our estimated annual effective tax rates from continuing operations for the six months ended April 30, 2015 and 2014 were a benefit of 67.7% and 16.9%, respectively. The increase in the 2015 effective tax rate is attributable to a discrete benefit item resulting from the reassessment of our uncertain tax position related to the 2008 spin-off of Quanex from a predecessor company in January 2015. Excluding this item, the effective tax rate was 35.5%. The 2014 effective rate was impacted by a change in the tax status of our facility in the United Kingdom (UK). On November 1, 2013, the assets of our UK branch were contributed to a newly formed wholly-owned UK subsidiary. This change resulted in a U.S. taxable charge that was booked as a discrete item in the first quarter of 2014. Excluding this discrete item, the 2014 effective tax rate was a benefit of 33.6%.

As of April 30, 2015, our unrecognized tax benefit (UTB) relates to certain state tax items regarding the interpretation of tax laws and regulations. The total UTB at October 31, 2014 included the UTB associated with the 2008 spin-off and totaled $11.4 million. Of this amount, $4.6 million was recorded as a liability for uncertain tax positions and $6.8 million was recorded as deferred income taxes (non-current assets) on the accompanying condensed consolidated balance sheet. In January 2015, we reassessed our unrecognized tax benefit related to the 2008 spin-off of Quanex from a predecessor company and recognized the full benefit of the tax positions taken. This reduced the liability for uncertain tax positions by $4.0 million and increased deferred income taxes (non-current assets) by $6.8 million and resulted in a non-cash increase in retained earnings of $10.0 million, with an increase in income tax benefit of $0.8 million. At April 30, 2015, $0.5 million is recorded as a liability for uncertain tax positions. The disallowance of the UTB would not materially affect the annual effective tax rate.

We evaluate the likelihood of realization of our deferred tax assets by considering both positive and negative evidence. We believe there is no need for a valuation allowance of the federal net operating losses. We will continue to evaluate our position throughout the year. We maintain a valuation allowance for certain state net operating losses which totaled $1.4 million at April 30, 2015.

Judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or 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 our financial statements. We are subject to the effect of these matters occurring in various jurisdictions. We do not believe any of the UTB at April 30, 2015 will be recognized within the next twelve months.

QUANEX BUILDING PRODUCTS CORPORATION

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

Our federal income tax returns for the tax years ended October 31, 2011 and 2012 were examined by the Internal Revenue Service and no adjustments were made.

9. Contingencies

Environmental

We are subject to extensive laws and regulations concerning the discharge of materials into the environment and the remediation of chemical contamination. We accrue our best estimates of our remediation obligations and adjust these accruals when further information becomes available or circumstances change. 

We are currently not subject to any remediation activities. Prior to April 1, 2014, we had remediation activities associated with one of our subsidiaries, Nichols Aluminum-Alabama, LLC, a component business unit of Nichols. As discussed in Note 1, "Nature of Operations and Basis of Presentation - Discontinued Operations", on April 1, 2014, we sold Nichols and the liabilities associated with this on-going remediation effort were assumed by Aleris International, Inc.

Spacer Migration

We were notified by certain customers through our German operation that the vapor barrier employed on certain spacer products manufactured prior to March 2014 may fail and permit spacer migration in certain extreme circumstances. This product does not have a specific customer warranty, but we have received claims from customers related to this issue, which we continue to investigate. We incurred expense of $1.8 million during 2014 associated with this issue, including an accrual of $1.2 million at October 31, 2014 for any asserted claim that we deem to be reasonably possible and estimable. The balance of this accrual at April 30, 2015 was $1.0 million, reflecting net claim payments of $0.3 million, additional claims received of approximately $0.2 million, and a translation adjustment of approximately $0.1 million. We cannot estimate any future liability with regard to unasserted claims. We will investigate any future claims, but we are not obligated to honor any future claims.

Affordable Care Act

We are subject to the employer-shared responsibility requirements (more commonly referred to as the employer mandate) of the Affordable Care Act (ACA). The employer mandate requires us to offer health care insurance that meets minimum value and affordability requirements to our full-time employees and certain potential common law employees within a specified coverage threshold. Effective January 1, 2015, and for the calendar year ended December 31, 2015, we may be subject to a penalty in the form of an excise tax under the ACA if we do not meet these requirements. Furthermore, we must comply with the annual disclosure and reporting requirements. We are evaluating these requirements and implementing mechanisms to achieve compliance.

Litigation

From time to time, we, along with our subsidiaries, are involved in various litigation matters arising in the ordinary course of our business. Although the ultimate resolution and impact of such litigation is not presently determinable, we believe that the eventual outcome of such litigation will not have a material adverse effect on our overall financial condition, results of operations or cash flows.

10. Derivative Instruments

Our derivative activities are subject to the management, direction, and control of the Chief Financial Officer and Chief Executive Officer. Certain transactions in excess of specified levels require further approval from the Board of Directors.

The nature of our business activities requires the management of various financial and market risks, including those related to changes in foreign currency exchange rates. We have historically used foreign currency forwards and options to mitigate or eliminate certain of those risks at our subsidiaries. We use foreign currency contracts to offset fluctuations in the value of accounts receivable and accounts payable balances that are denominated in currencies other than the United States dollar, including the Euro, British Pound and Canadian Dollar. Currently, we do not enter into derivative transactions for speculative or trading purposes. We are exposed to credit loss in the event of nonperformance by the counterparties to our derivative transactions. We attempt to mitigate this risk by monitoring the creditworthiness of our counterparties and limiting our exposure to individual counterparties. In addition, we have established master netting agreements in certain cases to facilitate the settlement of gains and losses on specific derivative contracts.

We have not designated any of our derivative contracts as hedges for accounting purposes in accordance with the provisions under the Accounting Standards Codification topic 815 "Derivatives and Hedging" (ASC 815). Therefore, changes in the fair

QUANEX BUILDING PRODUCTS CORPORATION

For the classification in the fair value hierarchy, see Note 11, "Fair Value Measurement of Assets and Liabilities", included herewith.

11. Fair Value Measurement of Assets and Liabilities

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity's own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to Level 1 and the lowest priority to Level 3. The three levels of the fair value hierarchy are described below:

• Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

• Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates) and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

• Level 3 - Inputs that are both significant to the fair value measurement and unobservable.

The following table summarizes the assets and liabilities measured on a recurring basis based on the fair value hierarchy (in thousands):

	April 30, 2015								October 31, 2014

We held short-term investments (with an original maturity of three months or less) in commercial paper at April 30, 2015 and October 31, 2014. We have included these investments as cash and cash equivalents in the accompanying condensed consolidated balance sheets. These investments are measured at fair value based on active market quotations and are therefore classified as Level 1. All of our derivative contracts are valued using quoted market prices from brokers or exchanges and are classified within Level 2 of the fair value hierarchy.

We had approximately $2.4 million of certain property, plant and equipment that was recorded at fair value on a non-recurring basis and classified as Level 3 as of April 30, 2015 and October 31, 2014. The fair value was based on broker opinions.

Carrying amounts reported on the balance sheet for cash, cash equivalents, accounts receivable and accounts payable approximate fair value due to the short-term maturity of these instruments. Our outstanding debt was variable rate debt that re-prices frequently, thereby limiting our exposure to significant change in interest rate risk. As a result, the fair value of our debt instruments approximates carrying value at April 30, 2015 and October 31, 2014 (Level 3 measurement).

12. Stock-Based Compensation

We have established and maintain an Omnibus Incentive Plan (2008 Plan) that provides for the granting of restricted stock awards, stock options, restricted stock units, performance share awards and other stock-based and cash-based awards. The 2008 Plan is administered by the Compensation and Management Development Committee of the Board of Directors.

The aggregate number of shares of common stock originally authorized for grant under the 2008 Plan was 2,900,000. In February 2011 and February 2014, shareholders approved an increase of the aggregate shares available for grant by 2,400,000 shares and 2,350,000 shares, respectively. Any officer, key employee and/or non-employee director is eligible for awards under the 2008 Plan. Our practice is to grant stock options and restricted stock units to non-employee directors on the last business day of each fiscal year, with an additional grant of options to each director on the date of his or her first anniversary of service. Once we receive approval from the Board of Directors in December, we grant stock options, restricted stock awards, restricted stock units and/or performance shares to officers, management and key employees. Occasionally, we may make additional grants to key employees at other times during the year.

Restricted Stock Awards

Restricted stock awards are granted to key employees and officers annually, and typically cliff vest over a three-year period with service and continued employment as the only vesting criteria. The recipient of the restricted stock awards is entitled to all of the rights of a shareholder, except that the awards are nontransferable during the vesting period. The fair value of the restricted stock award is established on the grant date and then expensed over the vesting period resulting in an increase in additional paid-in-capital. Shares are generally issued from treasury stock at the time of grant.

QUANEX BUILDING PRODUCTS CORPORATION

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

A summary of non-vested restricted stock awards activity during the six months ended April 30, 2015 is presented below:

	Restricted Stock Awards		Weighted Average Grant Date  Fair Value per Share
Non-vested at October 31, 2014	220,800		$	17.42
Granted	68,800		20.28
Cancelled	—		—
Vested	(33,500	)	15.08
Non-vested at April 30, 2015	256,100		$	18.49

The total weighted average grant-date fair value of restricted stock awards that vested during each of the six-month periods ended April 30, 2015 and 2014 was $0.5 million, respectively. As of April 30, 2015, total unrecognized compensation cost related to unamortized restricted stock awards was $2.3 million. We expect to recognize this expense over the remaining weighted average vesting period of 1.6 years.

Stock Options

Stock options are awarded to key employees, officers and non-employee directors. Director stock options vest immediately while employee and officer stock options typically vest ratably over a three-year period with service and continued employment as the vesting conditions. Our stock options may be exercised up to a maximum of ten years from the date of grant. The fair value of the stock options is determined on the grant date and expensed over the vesting period resulting in an increase in additional paid-in-capital.

We use a Black-Scholes pricing model to estimate the fair value of stock options. A description of the methodology for the valuation assumptions was disclosed in our Annual Report on Form 10-K for the fiscal year ended October 31, 2014.

The following table provides a summary of assumptions used to estimate the fair value of our stock options issued during the six-month periods ended April 30, 2015 and 2014.

	Six Months Ended
	April 30,
	2015	2014
Weighted-average expected volatility	47.7%	55.7%
Weighted-average expected term (in years)	5.6	5.9
Risk-free interest rate	1.6%	1.8%
Expected dividend yield over expected term	1.0%	1.0%
Weighted average grant date fair value	$8.40	$8.52

The following table summarizes our stock option activity for the six months ended April 30, 2015:

	Stock Options		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (000s)
Outstanding at October 31, 2014	2,588,389		$	16.21
Granted	123,900		20.28
Exercised	(273,950	)	15.26
Forfeited/Expired	(167	)	15.08
Outstanding at April 30, 2015	2,438,172		$	16.52	6.0	$	7,591
Vested or expected to vest at April 30, 2015	2,411,605		$	16.49	5.9	$	7,577
Exercisable at April 30, 2015	1,972,200		$	15.95	5.4	$	7,105

Intrinsic value is the amount by which the market price of the common stock on the date of exercise exceeds the exercise price of the stock option. The total intrinsic value of stock options exercised during the six months ended April 30, 2015 and 2014 was $1.1 million and $2.6 million. The weighted-average grant date fair value of stock options that vested during the six months

QUANEX BUILDING PRODUCTS CORPORATION

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

ended April 30, 2015 and 2014 was $2.3 million and $3.0 million, respectively. As of April 30, 2015, total unrecognized compensation cost related to stock options was $2.3 million. We expect to recognize this expense over the remaining weighted average vesting period of 1.5 years.

Restricted Stock Units

Restricted stock units may be awarded to key employees and officers from time to time, and annually to non-employee directors. The director restricted stock units vest immediately but are payable only upon the director's cessation of service, whereas restricted stock units awarded to employees and officers typically cliff vest after a three-year period with service and continued employment as the vesting conditions. Restricted stock units are not considered outstanding shares and do not have voting rights, although the holder does receive a cash payment equivalent to the dividend paid, on a one-for-one basis, on our outstanding common shares. Once the criteria is met, each restricted stock unit is payable to the holder in cash based on the market value of one share of our common stock. Accordingly, we record a liability for the restricted stock units on our balance sheet and recognize any changes in the market value during each reporting period as compensation expense.

The following table summarizes non-vested restricted stock unit activity during the six months ended April 30, 2015:

	Restricted Stock Units		Weighted Average Grant Date  Fair Value per Share
Non-vested at October 31, 2014	83,500		$	15.08
Vested	(83,500	)	15.08
Non-vested at April 30, 2015	—		$	—

During the six-month periods ended April 30, 2015 and 2014, we paid $1.7 million and $0.5 million, respectively, to settle certain restricted stock units.

Performance Share Awards

Historically, we have granted performance units to key employees and officers annually. These awards cliff vest after a three-year period with service and performance measures such as relative total shareholder return and earnings per share growth as vesting conditions. These awards were treated as a liability and marked to market based upon our assessment of the achievement of the performance measures, with the assistance of third-party compensation consultants.

For the annual grants which occurred in December 2014 and 2013, we granted performance shares rather than performance units. These performance share awards have the same performance measures (relative total shareholder return and earnings per share growth). However, the number of shares earned is variable depending on the metrics achieved, and the settlement method is 50% in cash and 50% in our common stock.

To account for these awards, we have bifurcated the portion subject to a market condition (relative total shareholder return) and the portion subject to an internal performance measure (earnings per share growth). We have further bifurcated these awards based on the settlement method, as the portion expected to settle in stock (equity component) and the portion expected to settle in cash (liability component).

To value the shares subject to the market condition, we utilized a Monte Carlo simulation model to arrive at a grant-date fair value. This amount will be expensed over the three-year term of the award with a credit to additional paid-in-capital. To value the shares subject to the internal performance measure, we used the value of our common stock on the date of grant as the grant-date fair value per share. This amount is being expensed over the three-year term of the award, with a credit to additional paid-in-capital, and could fluctuate depending on the number of shares ultimately expected to vest based on our assessment of the probability that the performance conditions will be achieved. For both performance conditions, the portion of the award expected to settle in cash is recorded as a liability and is being marked to market over the three-year term of the award, and can fluctuate depending on the number of shares ultimately expected to vest.

In conjunction with the annual grants in December 2014 and 2013, we awarded 137,400 and 155,800 performance shares, respectively, of which 0% to 200% of these shares may ultimately vest, depending on the achievement of the performance conditions. During 2014, 7,000 of the performance shares issued in December 2013 were forfeited. For the six-month periods ended April 30, 2015 and 2014, we have recorded $0.8 million and $0.5 million of compensation expense, respectively, related to these performance share awards.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

Performance share awards are not considered outstanding shares and do not have voting rights, although dividends are accrued over the performance period and will be payable in cash based upon the number of performance shares ultimately earned.

The performance shares are excluded from the diluted weighted-average shares used to calculate earnings per share until the performance criteria is probable to result in the issuance of contingent shares.

Treasury Shares

On September 5, 2014, our Board cancelled our existing stock repurchase program and approved a new stock repurchase program authorizing us to use up to $75.0 million to repurchase shares of our common stock. For the period from September 5, 2014 through October 31, 2014, we purchased 1,316,326 shares at a cost of $24.2 million under the new program. During the six months ended April 30, 2015, we purchased an additional 2,675,903 shares at a cost of $50.8 million. From inception of the program, we purchased 3,992,229 shares at a cost of $75.0 million.

We record treasury stock purchases under the cost method whereby the entire cost of the acquired stock is recorded as treasury stock. Shares are generally issued from treasury stock at the time of grant of restricted stock awards, and upon the exercise of stock options and upon the issuance of performance shares. On the subsequent issuance of treasury shares, we record proceeds in excess of cost as an increase in additional paid in capital. A deficiency of such proceeds relative to costs would be applied to reduce paid-in-capital associated with prior issuances to the extent available, with the remainder recorded as a charge to retained earnings. We recorded a charge to retained earnings of $0.7 million in March 2015.

The following table summarizes the treasury stock activity during the six months ended April 30, 2015:

	Six Months Ended
	April 30, 2015
Beginning balance as of November 1, 2014	1,417,700
Restricted stock awards granted	(68,800	)
Stock options exercised	(273,950	)
Shares purchased	2,675,903
Balance at end of period	3,750,853

13. Other Income (Expense)

Other income (expense) included under the caption "Other, net" on the accompanying condensed consolidated statements of income (loss), consisted of the following for the three- and six-month periods ended April 30, 2015 and 2014:

	Three Months Ended						Six Months Ended
	April 30,						April 30,
	2015			2014			2015			2014
	(In thousands)
Foreign currency transaction (losses) gains	$	(88	)	$	170		$	(922	)	$	66

Interest income	8			16			39			22
Other	3			—			3			80
Other (expense) income	$	(115	)	$	(22	)	$	(266	)	$	74

14. Earnings Per Share

We compute basic earnings per share by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per common and potential common shares include the weighted average of additional shares associated with the incremental effect of dilutive employee stock options, non-vested restricted stock as determined using the treasury stock method prescribed by U.S. GAAP and contingent shares associated with performance share awards, if dilutive.

The computation of diluted earnings per share excludes outstanding stock options and other common stock equivalents when their inclusion would be anti-dilutive. This is always the case when an entity incurs a net loss from continuing operations, as we

QUANEX BUILDING PRODUCTS CORPORATION

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

did for the six-month period ended April 30, 2015, as well as the three and six months ended April 30, 2014. During these periods, common stock equivalents of 451,590, 513,653, and 521,719, respectively, and restricted stock shares of 107,748, 107,589, and 95,912, respectively, were excluded from the computation of diluted earnings per share.

Basic and diluted earnings per share from continuing operations for the three-month period ended April 30, 2015 was calculated as follows (in thousands, except per share data):

	Three Months Ended April 30, 2015
	Net Income from Continuing Operations		Weighted Average Shares	Per Share
Basic earnings per common share	$	2,294	33,621	$	0.07
Effect of dilutive securities:
Stock options	—		429
Restricted stock awards	—		116
Diluted earnings per common share	$	2,294	34,166	$	0.07

For the three- and six-month periods ended April 30, 2015 and 2014, there were no potentially dilutive contingent shares related to performance share awards as the issuance of these shares was not yet deemed probable.

For each of the three- and six-month periods ended April 30, 2015, we had 731,272 securities, respectively, and for the three- and six-month periods ended April 30, 2014, we had 920,662 and 971,284 securities, respectively, that were potentially dilutive in future earnings per share calculations. Such dilution will be dependent on the excess of the market price of our stock over the exercise price and other components of the treasury stock method.

15. New Accounting Pronouncements

In April 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. This amendment requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with the treatment of debt discounts. This guidance becomes effective for financial statements issued for fiscal years beginning after December 15, 2015. We expect to adopt this guidance during fiscal 2017, and we are currently evaluating the impact on our consolidated financial statements.

In June 2014, the FASB issued ASU No. 2014-12, Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could be Achieved after the Requisite Service Period.  This amendment requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition that affects vesting or as a nonvesting condition that affects the grant-date fair value of an award, and provides explicit guidance for those awards. This guidance becomes effective for fiscal years beginning on or after December 15, 2015.  We expect to adopt this guidance during fiscal 2017, and we do not expect this pronouncement to have a material impact on our consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers.”  This guidance prescribes a methodology to determine when revenue is recognizable and constitutes a principles-based approach to revenue recognition based on the consideration to which the entity expects to be entitled in exchange for goods or services.  In addition, this guidance requires additional disclosure in the notes to the financial statements with regard to the methodology applied.  This pronouncement becomes effective for annual reporting periods beginning after December 15, 2016, and will essentially supersede and replace existing revenue recognition rules in U.S. GAAP, including industry-specific guidance.  We expect to adopt this pronouncement in fiscal 2018, and we are currently evaluating the impact on our consolidated financial statements.

In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This new guidance clarifies the definition of a discontinued operation as a disposal of a component of any entity, or a group of such components, which represent a strategic shift that has or will have a major effect on an entity’s operations and financial results.  This guidance should result in fewer applications of discontinued operations accounting treatment.  However, if such accounting treatment is required, the guidance requires additional footnote disclosures with regard to the major classes of line items constituting pretax profit or loss of the discontinued operation, a reconciliation of the major classes of assets and liabilities of the discontinued operation, and additional disclosure with regard to cash flows of the discontinued operation.  This guidance becomes effective for

QUANEX BUILDING PRODUCTS CORPORATION

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

fiscal years beginning on or after December 15, 2014.  We expect to adopt this guidance during fiscal 2016, and we are currently evaluating the impact on our consolidated financial statements.

In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which provides guidance related to the presentation of current and deferred income taxes on the balance sheet. In general, an entity must present an unrecognized tax benefit related to a net operating loss carryforward, similar tax loss or tax credit carryforward, as a reduction of a deferred tax asset, except in prescribed circumstances through which liability presentation would be appropriate. This guidance became effective for fiscal years beginning after December 15, 2013. We adopted this guidance on November 1, 2014 with no material impact on our consolidated financial statements.

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

The following discussion and analysis should be read in conjunction with the accompanying unaudited condensed consolidated financial statements and related notes as of April 30, 2015, and for the three- and six-month periods ended April 30, 2015 and 2014, included elsewhere herein. For additional information pertaining to our business, including risk factors which should be considered before investing in our common stock, refer to our Annual Report on Form 10-K for the fiscal year ended October 31, 2014.

Our Business

Quanex Building Products Corporation manufactures components primarily for the window and door (fenestration) industry, which include (1) energy-efficient flexible insulating glass spacers, (2) extruded vinyl profiles, (3) window and door screens, and (4) precision-formed metal and wood products for original equipment manufacturers (OEMs), as well as certain non-fenestration components, which include solar panel sealants, wood flooring and trim moldings. Quanex Building Products Corporation serves a primary customer base in North America and also serves customers in international markets through operating plants in the United Kingdom and Germany, as well as through sales and marketing efforts in other countries.

We continue to invest in organic growth initiatives and to pursue targeted business acquisitions, which may include vertically integrated vinyl extrusion businesses or screen manufacturers that allow us to expand our existing fenestration footprint, enhance our existing product offerings, acquire complementary technology, enhance our leadership position within the markets we serve, and expand into new markets or service lines.

We have four operating segments which we aggregate into one reportable business segment.

Recent Transactions and Events

Prior to April 1, 2014, we had two reportable business segments: (1) Engineered Products and (2) Aluminum Sheet Products. On April 1, 2014, we sold our interest in a limited liability company which held the assets of the Nichols Aluminum business (Nichols), the sole operating segment included in our Aluminum Sheet Products reportable segment, to Aleris International, Inc.

(Aleris), a privately held Delaware corporation which provides aluminum rolled products and extrusions, aluminum recycling and specification aluminum alloy production. We received gross proceeds of $110.0 million, which was reduced to $107.4 million, as a result of a working capital adjustment of $2.6 million that we paid in June 2014, resulting in a gain on the transaction of $24.1 million, net of related taxes of $15.1 million. We expect to continue to purchase aluminum product from Nichols, which has historically totaled approximately $12.0 million annually. Our purchases of aluminum product from Nichols for the three- and six-month periods ended April 30, 2015 and 2014 were $1.6 million and $6.2 million, respectively, and $3.3 million and $6.8 million, respectively.

In November 2013, Nichols experienced a fire at its Decatur, Alabama facility, which damaged a cold mill used to roll aluminum sheet to a desired thickness. The loss was insured, subject to a $0.5 million deductible. We capitalized $6.5 million to rebuild the asset, which was returned to service as of March 31, 2014. We incurred costs of $2.3 million associated with this loss, including an impairment of $0.5 million related to retirement of the asset, moving costs, outside service costs, clean-up and the deductible. To date, we have received insurance proceeds of $5.3 million. We revised our estimate of total insurance proceeds expected related to this loss to approximately $6.3 million, resulting in an expected gain on involuntary conversion of $3.9 million, of which we have recognized $2.9 million. We estimate the remaining pretax gain on involuntary conversion at $1.0 million and we expect this gain will be recognized during fiscal 2015, when and to the extent that insurance proceeds are received, which will result in an increase in income from discontinued operations, net of tax.

In December 2013, we acquired certain vinyl extrusion assets of Atrium Windows and Doors, Inc. (Atrium) at a facility in Greenville, Texas, for $5.2 million in cash (Greenville). We accounted for this transaction as a business combination resulting in an insignificant gain on the purchase. We entered into a supply agreement with Atrium related to the products manufactured at Greenville. We believe this acquisition expanded our vinyl extrusion capacity and positioned us with a platform from which to better serve our customers in the southern United States.

Market Overview and Outlook

We believe the primary drivers of our operating results continue to be new home construction and residential remodeling and replacement (R&R) activity. We believe that housing starts and window shipments are indicators of activity levels in the home building industry, and we use this data, as published by or derived from third-party sources, to evaluate the market.

Activity levels in the building products industry in the United States have increased annually since the recovery began in 2010, as evidenced by an increase in housing starts and window shipments. The National Association of Homebuilders (NAHB)

22

has forecasted calendar-year housing starts to increase from 1.0 million units in 2014 to 1.1 million units in 2015 and 1.3 million units in 2016, reflecting increasing consumer confidence and a healthier economy. Ducker Worldwide, LLC (Ducker), a consulting and research firm, indicated that window shipments in the R&R market are expected to increase from 28.0 million units in 2015 to 29.4 million units in 2016 and 30.5 million units in 2017, with new construction window shipments forecasted to increase at a higher pace. Derived from reports published by Ducker, the overall growth in window shipments for the trailing twelve-month period ended March 31, 2015 was 5.8%. During this period, growth in new construction increased 10.1%, while growth in R&R activity increased 2.9%. In recent years, growth in new construction has outpaced the growth in R&R, with a greater portion of the new construction associated with multi-family housing.

Higher energy efficiency standards in Europe are impacting the industry. We continue to be optimistic about our growth prospects in Europe, particularly in the United Kingdom, Germany and Scandinavian countries, where the push for higher energy efficiency standards has been the greatest. Older technology cold-edge spacers are still a dominant force in these regions and garner a larger portion of the total market share in Europe relative to the United States. We operate warm-edge spacer plants in the United Kingdom and Germany. We have encountered some spacer migration issues under extreme conditions for some spacer products sold by our German subsidiary. This issue was related to a vapor barrier that was discontinued in early 2014. Market conditions have slowed our near-term growth in Germany. However, we remain confident that we can become the provider of choice in Europe and the other markets we serve as demand for more energy-efficient warm edge spacers grows and eventually displaces cold edge spacers.

There are various internal and external factors that impact our operating results and challenge our growth prospects in the markets that we serve. Our business is subject to seasonality, as activity levels generally decline during the first half of the fiscal year and increase for the second half of the fiscal year. In addition, we utilize several commodities in our business for which pricing can fluctuate, including polyvinyl resin (PVC) and petroleum products. We typically include surcharges in our customer contracts which allow us to pass a portion of these price fluctuations onto our customers. However, during 2014 we were limited in our ability to recoup some of the increase in resin costs for certain customers of our vinyl extrusion products through surcharges due to contractual constraints. We renegotiated these customer contracts for the calendar year 2015. In addition, the price of crude oil per barrel has changed dramatically in recent months from a high of more than $100 per barrel to approximately $58 per barrel. Although we benefit from lower commodity prices associated with these petroleum products used in our business, our customer contracts may require concessions if oil prices per barrel decline below a designated threshold. Furthermore, with the recent weakening of the United States dollar relative to the euro and British pound, we have been impacted by foreign exchange losses which have reduced our short-term results in Europe. Ultimately, our profitability depends upon our ability to negotiate price, meet our customer’s product and delivery demands, manage our cost structure given these internal and external factors, and efficiently operate our facilities.

Net Sales. Net sales increased $6.7 million, or 5%, for the three months ended April 30, 2015 compared to the same period in 2014. The increase was generally due to higher activity levels in the fenestration industry, as the market continues a relatively steady recovery in terms of window shipments and housing starts. This trend, which is expected to continue for the foreseeable future, is evidenced by the year-over-year growth in window shipments as derived from preliminary data provided by Ducker for the calendar quarters ended March 31, 2015 and 2014, reflecting an overall growth rate of 6.3%, compared with a growth rate of 7.8%, for our year-over-year fiscal quarters ended April 30, 2015 and 2014, as adjusted for certain foreign and other results to be more comparable to Ducker. Of the $6.7 million increase in sales, $2.5 million was attributable to more favorable pricing for certain products and services, $5.6 million was attributable to increased volume, less an unfavorable foreign exchange rate impact of $2.5 million, with the remaining difference attributable to sales mix. We expect our growth rates to continue to converge with the Ducker growth rates throughout 2015.

Cost of Sales. The increase in cost of sales of $2.2 million, or 2%, for the three months ended April 30, 2015 compared to the same period in 2014, was at a slower pace than the 5% increase in net sales for the respective periods, as discussed above, resulting in more favorable margins for 2015. The increase in cost of sales was primarily driven by higher activity levels, but was also benefited by some labor efficiencies and favorable health insurance claims experience and recoveries. Additionally, we experienced lower incremental repair and maintenance costs year-over-year, as a disproportionately large amount of such costs were incurred in 2014 with regard to our vinyl extrusion plants.

Selling, General and Administrative. Our selling, general and administrative expenses decreased by $0.7 million, or 3%, for the three months ended April 30, 2015 compared to the same period in 2014. This decrease is primarily attributable the timing of incentive accruals between periods based on earnings, as well as a decrease in compensation expense associated with long-term incentive arrangements tied to the performance of our common stock. These decreases were partially offset by an increase in professional service fees.

Depreciation and Amortization. Depreciation and amortization expense decreased $0.7 million, or 8%, for the three months ended April 30, 2015 compared to the same period in 2014. This decrease in expense is associated with the normal run-off of depreciation and amortization of existing assets, partially offset by such expense incurred with regard to new assets placed into service during the trailing twelve months ended April 30, 2015.

Asset Impairment Charges. We recorded an impairment loss of $0.5 million in April 2014 to reduce the value of a facility in Barbourville, Kentucky to market value as of April 30, 2014. This facility was subsequently sold in May 2014, resulting in an insignificant realized loss on the sale. No such impairment was incurred during the three months ended April 30, 2015.

Interest Expense. Interest expense decreased $0.1 million for the three-months ended April 30, 2015 compared to the same period in 2014. This decrease is due to lower debt outstanding compared to 2014.

24

Other, net. The increase in other net expense of $0.1 million for the three months ended April 30, 2015 compared to the same period in 2014 was due primarily to net foreign exchange transaction losses.

Income Taxes. We recorded an income tax expense of $1.1 million for the three months ended April 30, 2015, an effective rate of 33.1%. For the three months ended April 30, 2014, we recorded an income tax benefit of $1.0 million, an effective rate of 32.2%. These results were driven by a change in pretax income (loss) for the respective periods. The remainder of the difference in the effective rates between these periods relates to the impact of permanent items and the foreign tax rate differential.

Income from Discontinued Operations, Net of Tax. We recorded a gain on the sale of Nichols of $24.6 million, net of tax of $15.1 million as of April 1, 2014. Excluding this gain, the loss from discontinued operations for the three-month period ended April 30, 2014 would have been a loss of $2.5 million due to the effect of aluminum commodity prices, which resulted in lower throughput and lower volume.

Net (loss) income	$	(0.8	)	$	16.2		$	(17.0	)	(105	)%

Net Sales. Net sales increased $8.3 million, or 3%, for the six months ended April 30, 2015 compared to the same period in 2014. The fenestration market grew throughout 2014 and continued to grow in 2015. The year-over-year growth in window shipments as derived from preliminary data provided by Ducker for the six months ended March 31, 2015 and 2014 was 6.8%, and, for the trailing twelve months then ended, 5.8%. By comparison, our sales growth was 4.3% and 3.6%, respectively, as adjusted for certain foreign and other results to be more comparable to Ducker. To some extent, the disparity between our growth rate and that of the broader market reflects timing of the recovery in the building products industry. For the first half of 2015, net sales increased $3.3 million as a result of favorable pricing and $7.0 million due to volume. Although we experienced a decrease in volume for one of our large customers, this has been more than offset by the Greenville acquisition volume and growth with other customers. These increases have been offset by a $3.5 million reduction associated with foreign exchange rate changes. The United States dollar has weakened during 2015 relative to the British pound and euro, which has resulted in a non-operational decrease in contribution from our foreign operations attributable to foreign exchange rate changes. The remainder of the overall sales increase was associated with sales mix. We expect our growth rates to continue to converge with the Ducker growth rates throughout 2015.

Cost of Sales. The increase in cost of sales of $11.8 million, or 6%, for the six months ended April 30, 2015 compared to the same period in 2014 exceeded a 3% increase in net sales for the respective periods. The increase in cost of sales is primarily due to increased activity levels. The results for 2014 benefited from a $2.8 million warranty reserve reversal with regard to certain spacer product for which claim activity had ceased. Excluding the impact of this item, cost of goods sold would have increased 4% year-over-year. To some extent, our labor and overhead efficiency decreased in 2015 relative to 2014, as we absorbed more cost in 2014 associated with the inventory build. By comparison, the seasonal build in 2015 has been at a slower pace, due to sufficient inventory on hand.

Selling, General and Administrative. Our selling, general and administrative expenses decreased by $3.8 million, or 9%, for the six months ended April 30, 2015 compared to the same period in 2014. This decrease is primarily due to lower headcount and workforce realignments during 2014, timing of incentive accruals based on operating results year-over-year, lower stock-based

25

compensation costs associated with long-term incentives tied to the price of our common stock, favorable decline in other operating costs including bad debt expense and software costs. These decreases were partially offset by a slight increase in professional service fees and higher insurance costs.

Depreciation and Amortization. Depreciation and amortization expense decreased $1.0 million, or 6%, for the six months ended April 30, 2015 compared to the same period in 2014. The results for the first half of 2014 included $0.5 million associated with the run-off of depreciation associated with an ERP project that was ceased in August 2013 as well as the impact of other asset retirements. These decreases in expense year-over-year were partially offset by incremental depreciation and amortization expense associated with fixed and intangible assets placed into service during the trailing twelve months ended April 30, 2015, as well as the incremental effect of the assets purchased in conjunction with the Greenville acquisition in December 2013.

Asset Impairment Charges. We recorded an impairment loss of $0.5 million in April 2014 to reduce the value of a facility in Barbourville, Kentucky to market value as of April 30, 2014. This facility was subsequently sold in May 2014, resulting in an insignificant realized loss on the sale. No such impairment was incurred during the six months ended April 30, 2015.

Interest Expense. Interest expense was consistent at $0.3 million for the six-month periods ended April 30, 2015 and 2014.

Other, net. The increase in other net expense of $0.4 million for the six months ended April 30, 2015 compared to the same period in 2014 was due primarily to net foreign exchange transaction losses.

Income Taxes. We recorded an income tax benefit of $1.7 million for the six months ended April 30, 2015, an effective rate of 67.7%, which included a discrete benefit of $0.8 million associated with the reversal of a liability for tax benefit associated with an uncertain tax position which stems from the 2008 spin-off of Quanex from a predecessor company. Excluding this discrete item, the effective tax rate would have been a benefit of 35.5%. For the six months ended April 30, 2014, we recorded an income tax benefit of $0.7 million, an effective rate of 16.9%, which included a discrete expense item of $0.7 million associated with the incorporation of the U.K. subsidiary. Excluding this discrete item, the effective tax rate would have been a benefit of 33.6%. The remaining difference in the effective rates between these periods relates to the impact of the foreign tax rate differential and permanent items.

Income from Discontinued Operations, Net of Tax. We recorded a gain on the sale of Nichols of $24.6 million, net of tax of $15.1 million as of April 1, 2014. Excluding this gain, we would have recorded a loss from discontinued operations of $5.2 million due primarily to the effect of relatively higher aluminum commodity prices, which resulted in lower throughput and lower volume.

Liquidity and Capital Resources

Overview

Our principal sources of funds are cash on hand, cash flow from operations, and borrowings under our $150 million Senior Unsecured Revolving Credit Facility (the Credit Facility).  As of April 30, 2015, we had $60.0 million of cash and cash equivalents, $143.4 million of availability under the Credit Facility and outstanding debt of $0.6 million, of which no amounts were outstanding under our Credit Facility.

Cash and cash equivalents decreased by $60.4 million during the six months ended April 30, 2015 due primarily to the purchase of treasury shares, capital investments in our manufacturing facilities, dividends paid and on-going operational activities.

Analysis of Cash Flow

The following table summarizes our cash flow results for the six months ended April 30, 2015 and 2014:

	Six Months Ended
	April 30,
	2015			2014
	(In millions)
Cash flows provided by (used for) operating activities	$	3.3		$	(11.0	)
Cash flows (used for) provided by investing activities	$	(12.7	)	$	87.9
Cash flows (used for) provided by financing activities	$	(51.4	)	$	0.4

Operating Activities. Cash provided by operating activities for the six-month period ended April 30, 2015 improved by approximately $14.3 million compared to the six-month period ended April 30, 2014. This is largely attributable to the Nichols

26

business which was sold on April 1, 2014, which contributed a net loss of $5.1 million for the period November 1, 2013 through April 1, 2014, before the gain on the sale, for which there was no activity for the same period in 2015. We combine the Nichols discontinued operations with our continuing operations for cash flow presentation as permitted by U.S. GAAP. In addition, we used cash to invest in inventory in prior year to prepare for busy season, and to a lesser extent in 2015. Working capital was $139.8 million, $186.2 million and $185.3 million as of April 30, 2015, October 31, 2014 and April 30, 2014, respectively.

Investing Activities. Cash used for investing activities for the six months ended April 30, 2015 increased by approximately $100.6 million compared to the six-month period ended April 30, 2014. The primary driver of this difference was the receipt of $110.0 million of proceeds from the sale of Nichols on April 1, 2014, partially offset by a decrease in cash invested in capital expenditures of $5.2 million year-over-year, and cash used for acquisitions of $5.2 million for the Greenville purchase in 2014.

Financing Activities. Cash used for financing activities was $51.4 million for the six-month period ended April 30, 2015, of which $52.7 million was used to purchase treasury stock and $2.8 million was used to pay dividends. These purchases were partially offset by $4.2 million of proceeds received from stock option exercises. We used $0.4 million for financing activities for the six months ended April 30, 2014, of which $3.0 million was used to pay dividends, partially offset by proceeds of $2.9 million received from stock option exercises.

Liquidity Requirements

Our strategy for deploying cash is to invest in organic growth opportunities, develop our infrastructure and make strategic acquisitions. Other uses of cash include paying cash dividends to our shareholders and opportunistically repurchasing our common stock. Any excess cash and cash equivalents are invested in commercial paper with terms of three months or less. Our investments are diversified across multiple institutions that we believe are financially sound. We intend to remain in commercial paper, 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, we may temporarily move funds into operating bank accounts of highly-rated financial institutions to meet on-going operational liquidity requirements. We did not experience any material losses on our cash and marketable securities investments during the six-month periods ended April 30, 2015 and 2014. We maintain cash balances in foreign countries which total $3.8 million as of April 30, 2015. We consider these funds to be permanently reinvested in these countries.

Senior Credit Facility

On January 28, 2013, we entered into a $150 million senior unsecured revolving credit facility that has a five-year term, maturing on January 28, 2018, and which permits aggregate borrowings at any time of up to $150 million, with a letter of credit sub-facility, a swing line sub-facility and a multi-currency sub-facility. Borrowings denominated in U.S dollars bear interest at a spread above LIBOR or a base rate derived from the prime rate. Foreign denominated borrowings bear interest at a spread above LIBOR applicable to such currencies. Subject to customary conditions, we may request that the aggregate commitments under the Credit Facility be increased by up to $100 million, with total commitments not to exceed $250 million.

The Credit Facility requires us to comply with certain financial covenants, the terms of which are defined therein. Specifically, we must not permit, on a quarterly basis, our ratio of consolidated EBITDA to consolidated interest expense as defined (Minimum Interest Coverage Ratio), to fall below 3.00:1, or our ratio of consolidated funded debt to consolidated EBITDA as defined (Maximum Consolidated Leverage Ratio), to exceed 3.25:1. The Maximum Consolidated Leverage 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 pro forma EBITDA of acquisitions and to exclude certain items such as goodwill and intangible asset impairments and certain other non-cash charges and non-recurring items. Subject to our compliance with the covenant requirements, the amount available under the Credit Facility is a function of: (1) our trailing twelve month EBITDA; (2) the Minimum Interest Coverage Ratio and Maximum Consolidated Leverage Ratio allowed under the Credit Facility; and (3) the aggregate amount of our outstanding debt and letters of credit. As of April 30, 2015, we were in compliance with the financial covenants set forth in the Credit Facility, as indicated in the table below:

	Required		Actual
Minimum Interest Coverage Ratio	No less than	3.00:1	87.95:1
Maximum Consolidated Leverage Ratio	No greater than	3.25:1	0.14:1

The Credit Facility also contains certain limitations on additional indebtedness, asset or equity sales and acquisitions. The payment of dividends and other distributions is permitted, provided there is no event of default after giving effect to such transactions. If the counterparties to the Credit Facility were unable to fulfill their commitments, the funds available to us could be reduced. However, we have no reason to believe that such liquidity will be unavailable or reduced.

27

We believe that we have sufficient funds and adequate financial resources available to meet our anticipated liquidity needs. We also believe our cash balances and cash flow from operations will be sufficient in the next twelve months and foreseeable future to finance our anticipated working capital requirements, capital expenditures, debt service requirements, and dividends.

As of April 30, 2015, the amount available to us for use under the Credit Facility was limited to $143.4 million and we had outstanding letters of credit of $5.9 million. For the six-month period ended April 30, 2015, we did not borrow any amount under the Credit Facility, and thus had no outstanding borrowings at April 30, 2015. Our current borrowing rate under the Credit Facility was 3.25% and 1.20% for the swing-line sub facility and the revolver, respectively, at April 30, 2015.

Repurchases of Outstanding Securities

On September 5, 2014, our Board cancelled our existing stock repurchase program and approved a new stock repurchase program authorizing us to use up to $75.0 million to repurchase shares of our common stock. These purchases were made in open market transactions or privately negotiated transactions in compliance with the Securities and Exchange Commission rule 10b5-1, subject to market conditions, applicable legal requirements and other relevant factors. Upon completion of the stock repurchase program during February 2015, our cumulative purchases pursuant to this plan were 3,992,229 shares totaling $75.0 million, an average price of $18.77 per share.

Critical Accounting Policies and Estimates

The preparation of our financial statements in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) requires us to make estimates and assumptions that affect the reported amount of assets, liabilities, revenues and expenses and related disclosures of contingent assets and liabilities. 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 our operating environment changes. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, and that we believe provide a basis for making judgments about the carrying value of assets and liabilities that are not readily available through open market quotes. We must use our judgment with regard to uncertainties in order to make these estimates. Actual results could differ from these estimates.

For a description of our critical accounting policies and estimates, see our Annual Report on Form 10-K for the fiscal year ended October 31, 2014. Our critical accounting policies and estimates have not changed materially during the six months ended April 30, 2015, except with regard to our critical accounting policy associated with income taxes pertaining to the reassessment of the liability for tax benefit associated with an uncertain tax position stemming from the 2008 spin-off of Quanex from its predecessor company. See a description in the accompanying Notes to Unaudited Condensed Consolidated Financial Statements, Note 8, "Income Taxes", contained elsewhere herein.

New Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the FASB or other standards setting bodies that we adopt as of the specified effective date. Unless otherwise discussed, we believe the impact of any other recently issued standards that are not yet effective are either not applicable to us at this time or will not have a material impact on our consolidated financial statements upon adoption. See Note 15, "New Accounting Pronouncements", contained elsewhere herein.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The following discussion of our exposure to various market risks contains “forward looking statements” regarding our estimates, assumptions and beliefs concerning our exposure. Although we believe these estimates and assumptions are reasonable in light of information currently available to us, we cannot provide assurance that these estimates will not materially differ from actual results due to the inherent unpredictability of interest rates, foreign currency rates and commodity prices as well as other factors. We do not use derivative financial instruments for speculative or trading purposes.

Interest Rate Risk

Our outstanding debt bears interest at variable rates and accordingly is sensitive to changes in interest rates. Based upon the balances of the variable rate debt at April 30, 2015, a hypothetical 1.0% increase or decrease in interest rates would result in a $0.01 million additional pretax charge or credit to our operating results.

Foreign Currency Rate Risk

Our international operations have exposure to foreign currency rate risks, primarily due to fluctuations in the Euro, the British Pound and the Canadian dollar. From time to time, we enter into foreign exchange contracts associated with our operations to

28

manage a portion of the foreign currency rate risk.

The notional and fair market values of these positions at April 30, 2015 and October 31, 2014, were as follows:

		Notional as indicated			Fair Value in $
		April 30, 2015	October 31, 2014		April 30, 2015			October 31, 2014
Foreign currency derivatives:		(In thousands)
Sell EUR, buy USD	EUR	7,555	$	4,907	$	289		$	68
Sell CAD, buy USD	CAD	296	331		2			1
Sell GBP, buy USD	GBP	267	—		6			—
Buy EUR, sell GBP	EUR	97	—		(2		)	—
Buy USD, sell EUR	USD	23	—		1			—
Buy GBP, sell EUR	GBP	5	—		—			—

At April 30, 2015 and October 31, 2014, we held foreign currency derivative contracts hedging cross-border intercompany and commercial activity for our insulating glass spacer business. Although these derivatives hedge our exposure to fluctuations in foreign currency rates, we do not apply hedge accounting and therefore, the change in the fair value of these foreign currency derivatives is recorded directly to other income and expense in the accompanying consolidated statements of income (loss). To the extent the gain or loss on the derivative instrument offsets the gain or loss from the remeasurement of the underlying foreign currency balance, changes in exchange rates should have no effect. See Note 10, "Derivative Instruments", contained elsewhere herein.

Commodity Price Risk

We purchase polyvinyl resin (PVC) as the significant raw material consumed in the manufacture of vinyl extrusions. We have a monthly resin adjuster in place with a majority of our customers and our resin supplier that is adjusted based upon published industry indices for resin prices for the prior month. This adjuster effectively shares the base pass-through price changes of PVC with our customers commensurate with the market at large. Our long-term exposure to changes in PVC prices is somewhat mitigated due to the contractual component of the resin adjuster program; however, there is a level of exposure to short-term volatility due to a one month lag and not all of our customer contracts include cost adjusters adequate to recover all exposure to such fluctuations. From time to time, we may lock in customer pricing for less than one year or make other customer concessions which result in us becoming exposed to fluctuations in resin pricing.

We maintain an oil-based materials surcharge on one of our major product lines. The surcharge is intended to offset the rising cost of products which are highly correlated to the price of oil, including butyl and other oil-based raw materials. The surcharge is in place with the majority of our customers who purchase these products and is adjusted monthly based upon the 90 day average published price for Brent crude. The oil-based raw materials purchased by us are subject to similar pricing schemes. Therefore, our long-term exposure to changes in oil-based raw material prices is significantly reduced under this surcharge program.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, we have evaluated the effectiveness of our 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 April 30, 2015. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of April 30, 2015, the disclosure controls and procedures are effective.

Changes in Internal Control over Financial Reporting

There have been no 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 our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Issuer Purchases of Equity Securities

On September 5, 2014, our Board of Directors approved a stock repurchase program authorizing us to use up to $75.0 million to repurchase shares of our common stock. For the period from September 5, 2014 through October 31, 2014, we purchased 1,316,326 shares at a cost of $24.2 million under this program. During the six months ended April 30, 2015, we purchased an additional 2,675,903 shares at a cost of $50.8 million. From inception of the program, we purchased 3,992,229 shares at a cost of $75.0 million. This program is now closed and no additional purchases are being made thereunder.

Set forth below is a table summarizing the program and the repurchase of shares during the quarter ended April 30, 2015.

New Accounting Pronouncements

New Accounting Pronouncements

In April 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. This amendment requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with the treatment of debt discounts. This guidance becomes effective for financial statements issued for fiscal years beginning after December 15, 2015. We expect to adopt this guidance during fiscal 2017, and we are currently evaluating the impact on our consolidated financial statements.

In June 2014, the FASB issued ASU No. 2014-12, Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could be Achieved after the Requisite Service Period.  This amendment requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition that affects vesting or as a nonvesting condition that affects the grant-date fair value of an award, and provides explicit guidance for those awards. This guidance becomes effective for fiscal years beginning on or after December 15, 2015.  We expect to adopt this guidance during fiscal 2017, and we do not expect this pronouncement to have a material impact on our consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers.”  This guidance prescribes a methodology to determine when revenue is recognizable and constitutes a principles-based approach to revenue recognition based on the consideration to which the entity expects to be entitled in exchange for goods or services.  In addition, this guidance requires additional disclosure in the notes to the financial statements with regard to the methodology applied.  This pronouncement becomes effective for annual reporting periods beginning after December 15, 2016, and will essentially supersede and replace existing revenue recognition rules in U.S. GAAP, including industry-specific guidance.  We expect to adopt this pronouncement in fiscal 2018, and we are currently evaluating the impact on our consolidated financial statements.

In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This new guidance clarifies the definition of a discontinued operation as a disposal of a component of any entity, or a group of such components, which represent a strategic shift that has or will have a major effect on an entity’s operations and financial results.  This guidance should result in fewer applications of discontinued operations accounting treatment.  However, if such accounting treatment is required, the guidance requires additional footnote disclosures with regard to the major classes of line items constituting pretax profit or loss of the discontinued operation, a reconciliation of the major classes of assets and liabilities of the discontinued operation, and additional disclosure with regard to cash flows of the discontinued operation.  This guidance becomes effective for fiscal years beginning on or after December 15, 2014.  We expect to adopt this guidance during fiscal 2016, and we are currently evaluating the impact on our consolidated financial statements.

In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which provides guidance related to the presentation of current and deferred income taxes on the balance sheet. In general, an entity must present an unrecognized tax benefit related to a net operating loss carryforward, similar tax loss or tax credit carryforward, as a reduction of a deferred tax asset, except in prescribed circumstances through which liability presentation would be appropriate. This guidance became effective for fiscal years beginning after December 15, 2013. We adopted this guidance on November 1, 2014 with no material impact on our consolidated financial statements.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

To determine our income tax expense for interim periods, consistent with accounting standards, we apply the estimated annual effective income tax rate to year-to-date results. Our estimated annual effective tax rates from continuing operations for the six months ended April 30, 2015 and 2014 were a benefit of 67.7% and 16.9%, respectively. The increase in the 2015 effective tax rate is attributable to a discrete benefit item resulting from the reassessment of our uncertain tax position related to the 2008 spin-off of Quanex from a predecessor company in January 2015. Excluding this item, the effective tax rate was 35.5%. The 2014 effective rate was impacted by a change in the tax status of our facility in the United Kingdom (UK). On November 1, 2013, the assets of our UK branch were contributed to a newly formed wholly-owned UK subsidiary. This change resulted in a U.S. taxable charge that was booked as a discrete item in the first quarter of 2014. Excluding this discrete item, the 2014 effective tax rate was a benefit of 33.6%.

As of April 30, 2015, our unrecognized tax benefit (UTB) relates to certain state tax items regarding the interpretation of tax laws and regulations. The total UTB at October 31, 2014 included the UTB associated with the 2008 spin-off and totaled $11.4 million. Of this amount, $4.6 million was recorded as a liability for uncertain tax positions and $6.8 million was recorded as deferred income taxes (non-current assets) on the accompanying condensed consolidated balance sheet. In January 2015, we reassessed our unrecognized tax benefit related to the 2008 spin-off of Quanex from a predecessor company and recognized the full benefit of the tax positions taken. This reduced the liability for uncertain tax positions by $4.0 million and increased deferred income taxes (non-current assets) by $6.8 million and resulted in a non-cash increase in retained earnings of $10.0 million, with an increase in income tax benefit of $0.8 million. At April 30, 2015, $0.5 million is recorded as a liability for uncertain tax positions. The disallowance of the UTB would not materially affect the annual effective tax rate.

We evaluate the likelihood of realization of our deferred tax assets by considering both positive and negative evidence. We believe there is no need for a valuation allowance of the federal net operating losses. We will continue to evaluate our position throughout the year. We maintain a valuation allowance for certain state net operating losses which totaled $1.4 million at April 30, 2015.

Judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or 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 our financial statements. We are subject to the effect of these matters occurring in various jurisdictions. We do not believe any of the UTB at April 30, 2015 will be recognized within the next twelve months.

Our federal income tax returns for the tax years ended October 31, 2011 and 2012 were examined by the Internal Revenue Service and no adjustments were made.

Contingencies

Contingencies

Environmental

We are subject to extensive laws and regulations concerning the discharge of materials into the environment and the remediation of chemical contamination. We accrue our best estimates of our remediation obligations and adjust these accruals when further information becomes available or circumstances change. 

We are currently not subject to any remediation activities. Prior to April 1, 2014, we had remediation activities associated with one of our subsidiaries, Nichols Aluminum-Alabama, LLC, a component business unit of Nichols. As discussed in Note 1, "Nature of Operations and Basis of Presentation - Discontinued Operations", on April 1, 2014, we sold Nichols and the liabilities associated with this on-going remediation effort were assumed by Aleris International, Inc.

Spacer Migration

We were notified by certain customers through our German operation that the vapor barrier employed on certain spacer products manufactured prior to March 2014 may fail and permit spacer migration in certain extreme circumstances. This product does not have a specific customer warranty, but we have received claims from customers related to this issue, which we continue to investigate. We incurred expense of $1.8 million during 2014 associated with this issue, including an accrual of $1.2 million at October 31, 2014 for any asserted claim that we deem to be reasonably possible and estimable. The balance of this accrual at April 30, 2015 was $1.0 million, reflecting net claim payments of $0.3 million, additional claims received of approximately $0.2 million, and a translation adjustment of approximately $0.1 million. We cannot estimate any future liability with regard to unasserted claims. We will investigate any future claims, but we are not obligated to honor any future claims.

Affordable Care Act

We are subject to the employer-shared responsibility requirements (more commonly referred to as the employer mandate) of the Affordable Care Act (ACA). The employer mandate requires us to offer health care insurance that meets minimum value and affordability requirements to our full-time employees and certain potential common law employees within a specified coverage threshold. Effective January 1, 2015, and for the calendar year ended December 31, 2015, we may be subject to a penalty in the form of an excise tax under the ACA if we do not meet these requirements. Furthermore, we must comply with the annual disclosure and reporting requirements. We are evaluating these requirements and implementing mechanisms to achieve compliance.

Litigation

From time to time, we, along with our subsidiaries, are involved in various litigation matters arising in the ordinary course of our business. Although the ultimate resolution and impact of such litigation is not presently determinable, we believe that the eventual outcome of such litigation will not have a material adverse effect on our overall financial condition, results of operations or cash flows.

Inventories

Inventories consisted of the following at April 30, 2015 and October 31, 2014:

	April 30, 2015		October 31, 2014
	(In thousands)
Raw materials	$	39,928	$	36,751
Finished goods and work in process	29,126		25,558
Supplies and other	1,225		806
Total	70,279		63,115
Less: Inventory reserves	7,285		5,757
Inventories, net	$	62,994	$	57,358

Fixed costs related to excess manufacturing capacity, if any, have been expensed in the period they were incurred and, therefore, are not capitalized into inventory.

Our inventories at April 30, 2015 and October 31, 2014 were valued using the following costing methods:

	April 30, 2015		October 31, 2014
	(In thousands)
LIFO	$	6,048	$	5,122
FIFO	56,946		52,236
Total	$	62,994	$	57,358

During interim periods, we estimate a LIFO reserve based on our expectations of year-end inventory levels and costs. If our calculations indicate that an adjustment at year-end will be required, we record a proportionate share of this amount during the period. At year-end, we calculate the actual LIFO reserve and record an adjustment for the difference between the annual calculation and any estimates recognized during the interim periods.  Because the interim projections are subject to many factors beyond our control, the results could differ significantly from the year-end LIFO calculation. We recorded no interim LIFO reserve adjustment for the three- and six-month periods ended April 30, 2015 and 2014.     

For inventories valued under the LIFO method, replacement cost exceeded the LIFO value by approximately $1.4 million at April 30, 2015 and October 31, 2014.

Acquisitions

Acquisitions

On December 31, 2013, we acquired certain vinyl extrusion assets of Atrium Windows and Doors, Inc. (Atrium) at a facility in Greenville, Texas, for $5.2 million in cash (Greenville). We accounted for this transaction as a business combination resulting in an insignificant gain on the purchase. We entered into a supply agreement with Atrium related to the products produced at Greenville. We believe this acquisition expanded our vinyl extrusion capacity and positioned us with a platform from which to better serve our customers in the southern United States.

The purchase price has been allocated to the fair value of the assets acquired and liabilities assumed, as indicated in the table below.

	As of Date of Opening Balance Sheet
	(In thousands)
Net assets acquired:
Inventories	$	161
Prepaid and other current assets	145
Property, plant and equipment	4,695
Intangible assets	290
Deferred income tax liability	(50		)
Net assets acquired	$	5,241
Consideration:
Cash, net of cash and cash equivalents acquired	$	5,161
Gain recognized on bargain purchase	$	80

We used recognized valuation techniques to determine the fair value of the assets and liabilities, including the income approach for customer relationships, with a discount rate that reflects the risk of the expected future cash flows. The gain on bargain purchase of approximately $0.1 million is included in "Other, net" on our condensed consolidated statement of income (loss) for the six months ended April 30, 2014.

Pro forma results of operations were omitted because this acquisition was not deemed to be material to our results of operations for the six months ended April 30, 2014.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

We compute basic earnings per share by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per common and potential common shares include the weighted average of additional shares associated with the incremental effect of dilutive employee stock options, non-vested restricted stock as determined using the treasury stock method prescribed by U.S. GAAP and contingent shares associated with performance share awards, if dilutive.

The computation of diluted earnings per share excludes outstanding stock options and other common stock equivalents when their inclusion would be anti-dilutive. This is always the case when an entity incurs a net loss from continuing operations, as we did for the six-month period ended April 30, 2015, as well as the three and six months ended April 30, 2014. During these periods, common stock equivalents of 451,590, 513,653, and 521,719, respectively, and restricted stock shares of 107,748, 107,589, and 95,912, respectively, were excluded from the computation of diluted earnings per share.

Basic and diluted earnings per share from continuing operations for the three-month period ended April 30, 2015 was calculated as follows (in thousands, except per share data):

	Three Months Ended April 30, 2015
	Net Income from Continuing Operations		Weighted Average Shares	Per Share
Basic earnings per common share	$	2,294	33,621	$	0.07
Effect of dilutive securities:
Stock options	—		429
Restricted stock awards	—		116
Diluted earnings per common share	$	2,294	34,166	$	0.07

For the three- and six-month periods ended April 30, 2015 and 2014, there were no potentially dilutive contingent shares related to performance share awards as the issuance of these shares was not yet deemed probable.

For each of the three- and six-month periods ended April 30, 2015, we had 731,272 securities, respectively, and for the three- and six-month periods ended April 30, 2014, we had 920,662 and 971,284 securities, respectively, that were potentially dilutive in future earnings per share calculations. Such dilution will be dependent on the excess of the market price of our stock over the exercise price and other components of the treasury stock method.

Derivative Instruments

Derivative Instruments

Our derivative activities are subject to the management, direction, and control of the Chief Financial Officer and Chief Executive Officer. Certain transactions in excess of specified levels require further approval from the Board of Directors.

The nature of our business activities requires the management of various financial and market risks, including those related to changes in foreign currency exchange rates. We have historically used foreign currency forwards and options to mitigate or eliminate certain of those risks at our subsidiaries. We use foreign currency contracts to offset fluctuations in the value of accounts receivable and accounts payable balances that are denominated in currencies other than the United States dollar, including the Euro, British Pound and Canadian Dollar. Currently, we do not enter into derivative transactions for speculative or trading purposes. We are exposed to credit loss in the event of nonperformance by the counterparties to our derivative transactions. We attempt to mitigate this risk by monitoring the creditworthiness of our counterparties and limiting our exposure to individual counterparties. In addition, we have established master netting agreements in certain cases to facilitate the settlement of gains and losses on specific derivative contracts.

We have not designated any of our derivative contracts as hedges for accounting purposes in accordance with the provisions under the Accounting Standards Codification topic 815 "Derivatives and Hedging" (ASC 815). Therefore, changes in the fair value of these contracts and the realized gains and losses are recorded in the condensed consolidated statements of income (loss) for the three- and six-month periods ended April 30, 2015 and 2014 as follows (in thousands):

		Three Months Ended						Six Months Ended

We have chosen not to offset any of our derivative instruments in accordance with the provisions of ASC 815. Therefore, the assets and liabilities are presented on a gross basis on our accompanying condensed consolidated balance sheets.

The fair values of our outstanding derivative contracts as of April 30, 2015 and October 31, 2014 were as follows (in thousands):

Other Plans

We also have a supplemental benefit plan covering certain executive officers and a non-qualified deferred compensation plan covering members of the Board of Directors and certain key employees. As of April 30, 2015 and October 31, 2014, our liability under the supplemental benefit plan was approximately $1.8 million and $1.9 million, respectively, and under the deferred compensation plan was approximately $3.4 million for both periods. In January 2014, we paid $3.3 million related to the deferred compensation plan as a result of the separation of our former chief executive officer in July 2013. We record the current portion of liabilities under these plans under the caption "Accrued Liabilities," and the long-term portion under the caption "Other Liabilities" in the accompanying balance sheets.

During the fourth quarter of 2014, we evaluated our goodwill balances for indicators of impairment and performed an annual goodwill impairment test to determine the recoverability of these assets. Three of our reporting units had goodwill at October 31, 2014 which totaled $55.2 million, $12.6 million and $2.8 million. We determined that our goodwill was not impaired and there have been no triggering events to indicate impairment during the six months ended April 30, 2015, so no additional testing was deemed necessary.

Identifiable Intangible Assets

Amortizable intangible assets consisted of the following as of April 30, 2015 and October 31, 2014:

We do not estimate a residual value associated with these intangible assets. Included in intangible assets as of April 30, 2015 were customer relationships of $0.2 million associated with the Greenville acquisition. These assets have estimated remaining useful lives of four years. See Note 2, "Acquisitions", included herewith.

For the three- and six-month periods ended April 30, 2015 and 2014, we had aggregate amortization expense of $2.2 million and $4.5 million, respectively, and $2.3 million and $4.6 million, respectively.

Long-term debt	$	455	$	586

On January 28, 2013, we entered into a Senior Unsecured Revolving Credit Facility (the Credit Facility) that has a five-year term and permits aggregate borrowings at any time of up to $150.0 million, with a letter of credit sub-facility, a swing line sub-facility and a multi-currency sub-facility. Borrowings denominated in United States dollars bear interest at a spread above the London Interbank Borrowing Rate (LIBOR) or a base rate derived from the prime rate. Foreign denominated borrowings bear interest at a spread above the LIBOR applicable to such currencies. Subject to customary conditions, we may request that the aggregate commitments under the Credit Facility be increased by up to $100.0 million, with total commitments not to exceed $250.0 million.

The Credit Facility requires us to comply with certain financial covenants, the terms of which are defined therein. Specifically, we must not permit, on a quarterly basis, our ratio of consolidated EBITDA to consolidated interest expense as defined (Minimum Interest Coverage Ratio), to fall below 3.00:1 or our ratio of consolidated funded debt to consolidated EBITDA, as defined (Maximum Consolidated Leverage Ratio), to exceed 3.25:1. The Maximum Consolidated Leverage 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 pro forma EBITDA of acquisitions and to exclude certain items such as goodwill and intangible asset impairments and certain other non-cash charges and non-recurring items. Subject to our compliance with the covenant requirements, the amount available under the Credit Facility is a function of: (1) our trailing twelve-month EBITDA; (2) the Minimum Interest Coverage Ratio and Maximum Consolidated Leverage Ratio allowed under the Credit Facility; and (3) the aggregate amount of our outstanding debt and letters of credit. As of April 30, 2015, we were in compliance with the financial covenants set forth in the Credit Facility.

As of April 30, 2015, the amount available to us for use under the Credit Facility was $143.4 million and we had outstanding letters of credit of $5.9 million. For the six-month period ended April 30, 2015, we did not borrow any amounts under the Credit Facility, and thus had no outstanding borrowings at April 30, 2015. Our current borrowing rate under the Credit Facility was 3.25% and 1.20% for the swing-line sub facility and the revolver, respectively, at April 30, 2015. As of October 31, 2014, the amount available to us for use under the Credit Facility was $140.7 million and we had outstanding letters of credit of $6.1 million. Our borrowing rate under the Credit Facility was 3.25% and 1.20% for the swing-line sub facility and the revolver, respectively, at October 31, 2014.

Warranty Obligations

Warranty Obligations

We accrue warranty obligations as we recognize revenue associated with certain products. We make provisions for our warranty obligations based upon historical experience of costs incurred for such obligations adjusted, as necessary, for current conditions and factors. During January 2014, we reduced our warranty accrual by $2.8 million for certain products associated with our insulating glass business that were discontinued in a prior year and for which claim activity for a particular customer had ceased. There are significant uncertainties and judgments involved in estimating our warranty obligations, including changing product designs, differences in customer installation processes and future claims experience which may vary from historical claims experience. Therefore, the ultimate amount we incur as warranty costs in the near and long-term may not be consistent with our current estimate.

A reconciliation of the activity related to our accrued warranty, including both the current and long-term portions (reported in accrued liabilities and other liabilities, respectively, on the accompanying condensed consolidated balance sheet) follows:

	Six Months Ended
	April 30, 2015

Less: Current portion of accrued warranty	678
Long-term portion of accrued warranty	$	231

The increase in the warranty provision during the six months ended April 30, 2015 was primarily attributable to a specific claim related to our vinyl extrusion products stemming from a change in formulation.

Stock-Based Compensation

Stock-Based Compensation

We have established and maintain an Omnibus Incentive Plan (2008 Plan) that provides for the granting of restricted stock awards, stock options, restricted stock units, performance share awards and other stock-based and cash-based awards. The 2008 Plan is administered by the Compensation and Management Development Committee of the Board of Directors.

The aggregate number of shares of common stock originally authorized for grant under the 2008 Plan was 2,900,000. In February 2011 and February 2014, shareholders approved an increase of the aggregate shares available for grant by 2,400,000 shares and 2,350,000 shares, respectively. Any officer, key employee and/or non-employee director is eligible for awards under the 2008 Plan. Our practice is to grant stock options and restricted stock units to non-employee directors on the last business day of each fiscal year, with an additional grant of options to each director on the date of his or her first anniversary of service. Once we receive approval from the Board of Directors in December, we grant stock options, restricted stock awards, restricted stock units and/or performance shares to officers, management and key employees. Occasionally, we may make additional grants to key employees at other times during the year.

Restricted Stock Awards

Restricted stock awards are granted to key employees and officers annually, and typically cliff vest over a three-year period with service and continued employment as the only vesting criteria. The recipient of the restricted stock awards is entitled to all of the rights of a shareholder, except that the awards are nontransferable during the vesting period. The fair value of the restricted stock award is established on the grant date and then expensed over the vesting period resulting in an increase in additional paid-in-capital. Shares are generally issued from treasury stock at the time of grant.

A summary of non-vested restricted stock awards activity during the six months ended April 30, 2015 is presented below:

	Restricted Stock Awards		Weighted Average Grant Date  Fair Value per Share
Non-vested at October 31, 2014	220,800		$	17.42
Granted	68,800		20.28
Cancelled	—		—
Vested	(33,500	)	15.08
Non-vested at April 30, 2015	256,100		$	18.49

The total weighted average grant-date fair value of restricted stock awards that vested during each of the six-month periods ended April 30, 2015 and 2014 was $0.5 million, respectively. As of April 30, 2015, total unrecognized compensation cost related to unamortized restricted stock awards was $2.3 million. We expect to recognize this expense over the remaining weighted average vesting period of 1.6 years.

Stock Options

Stock options are awarded to key employees, officers and non-employee directors. Director stock options vest immediately while employee and officer stock options typically vest ratably over a three-year period with service and continued employment as the vesting conditions. Our stock options may be exercised up to a maximum of ten years from the date of grant. The fair value of the stock options is determined on the grant date and expensed over the vesting period resulting in an increase in additional paid-in-capital.

We use a Black-Scholes pricing model to estimate the fair value of stock options. A description of the methodology for the valuation assumptions was disclosed in our Annual Report on Form 10-K for the fiscal year ended October 31, 2014.

The following table provides a summary of assumptions used to estimate the fair value of our stock options issued during the six-month periods ended April 30, 2015 and 2014.

	Six Months Ended

Expected dividend yield over expected term	1.0%	1.0%
Weighted average grant date fair value	$8.40	$8.52

The following table summarizes our stock option activity for the six months ended April 30, 2015:

	Stock Options		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (000s)
Outstanding at October 31, 2014	2,588,389		$	16.21

Exercised	(273,950	)	15.26
Forfeited/Expired	(167	)	15.08
Outstanding at April 30, 2015	2,438,172		$	16.52	6.0	$	7,591
Vested or expected to vest at April 30, 2015	2,411,605		$	16.49	5.9	$	7,577
Exercisable at April 30, 2015	1,972,200		$	15.95	5.4	$	7,105

Intrinsic value is the amount by which the market price of the common stock on the date of exercise exceeds the exercise price of the stock option. The total intrinsic value of stock options exercised during the six months ended April 30, 2015 and 2014 was $1.1 million and $2.6 million. The weighted-average grant date fair value of stock options that vested during the six months ended April 30, 2015 and 2014 was $2.3 million and $3.0 million, respectively. As of April 30, 2015, total unrecognized compensation cost related to stock options was $2.3 million. We expect to recognize this expense over the remaining weighted average vesting period of 1.5 years.

Restricted Stock Units

Restricted stock units may be awarded to key employees and officers from time to time, and annually to non-employee directors. The director restricted stock units vest immediately but are payable only upon the director's cessation of service, whereas restricted stock units awarded to employees and officers typically cliff vest after a three-year period with service and continued employment as the vesting conditions. Restricted stock units are not considered outstanding shares and do not have voting rights, although the holder does receive a cash payment equivalent to the dividend paid, on a one-for-one basis, on our outstanding common shares. Once the criteria is met, each restricted stock unit is payable to the holder in cash based on the market value of one share of our common stock. Accordingly, we record a liability for the restricted stock units on our balance sheet and recognize any changes in the market value during each reporting period as compensation expense.

The following table summarizes non-vested restricted stock unit activity during the six months ended April 30, 2015:

	Restricted Stock Units		Weighted Average Grant Date  Fair Value per Share
Non-vested at October 31, 2014	83,500		$	15.08
Vested	(83,500	)	15.08
Non-vested at April 30, 2015	—		$	—

During the six-month periods ended April 30, 2015 and 2014, we paid $1.7 million and $0.5 million, respectively, to settle certain restricted stock units.

Performance Share Awards

Historically, we have granted performance units to key employees and officers annually. These awards cliff vest after a three-year period with service and performance measures such as relative total shareholder return and earnings per share growth as vesting conditions. These awards were treated as a liability and marked to market based upon our assessment of the achievement of the performance measures, with the assistance of third-party compensation consultants.

For the annual grants which occurred in December 2014 and 2013, we granted performance shares rather than performance units. These performance share awards have the same performance measures (relative total shareholder return and earnings per share growth). However, the number of shares earned is variable depending on the metrics achieved, and the settlement method is 50% in cash and 50% in our common stock.

To account for these awards, we have bifurcated the portion subject to a market condition (relative total shareholder return) and the portion subject to an internal performance measure (earnings per share growth). We have further bifurcated these awards based on the settlement method, as the portion expected to settle in stock (equity component) and the portion expected to settle in cash (liability component).

To value the shares subject to the market condition, we utilized a Monte Carlo simulation model to arrive at a grant-date fair value. This amount will be expensed over the three-year term of the award with a credit to additional paid-in-capital. To value the shares subject to the internal performance measure, we used the value of our common stock on the date of grant as the grant-date fair value per share. This amount is being expensed over the three-year term of the award, with a credit to additional paid-in-capital, and could fluctuate depending on the number of shares ultimately expected to vest based on our assessment of the probability that the performance conditions will be achieved. For both performance conditions, the portion of the award expected to settle in cash is recorded as a liability and is being marked to market over the three-year term of the award, and can fluctuate depending on the number of shares ultimately expected to vest.

In conjunction with the annual grants in December 2014 and 2013, we awarded 137,400 and 155,800 performance shares, respectively, of which 0% to 200% of these shares may ultimately vest, depending on the achievement of the performance conditions. During 2014, 7,000 of the performance shares issued in December 2013 were forfeited. For the six-month periods ended April 30, 2015 and 2014, we have recorded $0.8 million and $0.5 million of compensation expense, respectively, related to these performance share awards.

Performance share awards are not considered outstanding shares and do not have voting rights, although dividends are accrued over the performance period and will be payable in cash based upon the number of performance shares ultimately earned.

The performance shares are excluded from the diluted weighted-average shares used to calculate earnings per share until the performance criteria is probable to result in the issuance of contingent shares.

Treasury Shares

On September 5, 2014, our Board cancelled our existing stock repurchase program and approved a new stock repurchase program authorizing us to use up to $75.0 million to repurchase shares of our common stock. For the period from September 5, 2014 through October 31, 2014, we purchased 1,316,326 shares at a cost of $24.2 million under the new program. During the six months ended April 30, 2015, we purchased an additional 2,675,903 shares at a cost of $50.8 million. From inception of the program, we purchased 3,992,229 shares at a cost of $75.0 million.

We record treasury stock purchases under the cost method whereby the entire cost of the acquired stock is recorded as treasury stock. Shares are generally issued from treasury stock at the time of grant of restricted stock awards, and upon the exercise of stock options and upon the issuance of performance shares. On the subsequent issuance of treasury shares, we record proceeds in excess of cost as an increase in additional paid in capital. A deficiency of such proceeds relative to costs would be applied to reduce paid-in-capital associated with prior issuances to the extent available, with the remainder recorded as a charge to retained earnings. We recorded a charge to retained earnings of $0.7 million in March 2015.

The following table summarizes the treasury stock activity during the six months ended April 30, 2015:

Nature of Operations and Basis of Presentation

Nature of Operations and Basis of Presentation

Quanex Building Products Corporation manufactures components primarily for the window and door (fenestration) industry, which include (1) energy-efficient flexible insulating glass spacers, (2) extruded vinyl profiles, (3) window and door screens, and (4) precision-formed metal and wood products for original equipment manufacturers (OEMs), as well as certain non-fenestration components, which include solar panel sealants, wood flooring and trim moldings. Quanex Building Products Corporation serves a primary customer base in North America and also serves customers in international markets through operating plants in the United Kingdom and Germany, as well as through sales and marketing efforts in other countries.

Unless the context indicates otherwise, references to "Quanex", the "Company", "we", "us" and "our" refer to the consolidated business operations of Quanex Building Products Corporation and its subsidiaries.

The accompanying interim condensed consolidated financial statements include the accounts of Quanex Building Products Corporation. All intercompany accounts and transactions have been eliminated in consolidation. These financial statements have been prepared by us, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. The consolidated balance sheet as of October 31, 2014 was derived from audited financial information, but does not include all disclosures required by U.S. GAAP. The accompanying financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto, included in our Annual Report on Form 10-K for the fiscal year ended October 31, 2014. In our opinion, the accompanying financial statements contain all adjustments (which consist of normal recurring adjustments, except as disclosed herein) necessary to fairly present our financial position, results of operations and cash flows for the interim periods. The results of operations for the periods presented are not necessarily indicative of the results to be expected for the full year or for any future periods.

In preparing financial statements, we make informed judgments and estimates that affect the reported amounts of assets and liabilities as of the date of the financial statements and affect the reported amounts of revenues and expenses during the reporting period. We review our estimates on an on-going basis, including those related to impairment of long lived assets and goodwill, contingencies and income taxes. Changes in facts and circumstances may result in revised estimates and actual results may differ from these estimates.

Discontinued Operations

Prior to April 1, 2014, we had two reportable business segments: (1) Engineered Products and (2) Aluminum Sheet Products. On April 1, 2014, we sold our interest in a limited liability company which held the assets of the Nichols Aluminum business (Nichols), the sole operating segment included in our Aluminum Sheet Products reportable segment, to Aleris International, Inc.

(Aleris), a privately held Delaware corporation which provides aluminum rolled products and extrusions, aluminum recycling and specification aluminum alloy production. We received gross proceeds of $110.0 million, which was reduced to $107.4 million, reflecting a net working capital adjustment of $2.6 million that we paid in June 2014, resulting in a net gain on the transaction of $24.1 million, net of related taxes of $15.1 million.

Nichols represented a significant portion of our assets and operations. We accounted for this sale as a discontinued operation. We revised our financial statements and removed the results of operations of Nichols from net income (loss) from continuing operations, and presented separately as income (loss) from discontinued operations, net of taxes, for each of the accompanying condensed consolidated statements of income (loss). Unless noted otherwise, the notes to the consolidated financial statements pertain to our continuing operations.

For cash flow statement presentation, the sources and uses of cash for Nichols are presented as operating, investing and financing cash flows, as applicable, combined with such cash flows for continuing operations for the period from November 1, 2013 to April 1, 2014, as permitted by U.S. GAAP.

We have historically purchased rolled aluminum product from Nichols. We expect to continue to purchase aluminum from Nichols in the normal course of business. We considered whether these aluminum purchases and the services provided under a transition services agreement for the period from April 1, 2014 to May 31, 2014 constituted significant continuing involvement with Nichols. Since these purchases were in the normal course of business and the services provided were for a relatively short period and are customary for similar transactions, we determined that this involvement was not deemed significant and did not preclude accounting for the transaction as a discontinued operation. Our purchases of aluminum product from Nichols for the three- and six-month periods ended April 30, 2015 and 2014 were $1.6 million and $6.2 million, respectively, and $3.3 million and $6.8 million, respectively.

In November 2013, Nichols experienced a fire at its Decatur, Alabama facility, which damaged a cold mill used to roll aluminum sheet to a desired thickness. The loss was insured, subject to a $0.5 million deductible. We capitalized $6.5 million to rebuild the asset, which was returned to service as of March 31, 2014. We incurred costs of $2.3 million associated with this loss, including an impairment of $0.5 million related to retirement of the asset, moving costs, outside service costs, clean-up and the deductible. To date, we have received insurance proceeds of $5.3 million. We have reduced our estimate of total insurance proceeds expected related to this loss to approximately $6.3 million, resulting in an expected gain on involuntary conversion of $3.9 million of which we have recognized $2.9 million. We estimate the remaining pretax gain on involuntary conversion at $1.0 million and that this gain will be recognized during fiscal 2015, when and to the extent that insurance proceeds are received, which will result in an increase in income from discontinued operations, net of tax.

Income from discontinued operations for the six months ended April 30, 2015 reflects the receipt of insurance proceeds of $0.5 million, less approximately $0.5 million associated with a health insurance claim amount reimbursable to the stop-loss insurance provider.

The following table summarizes the operating results for Nichols, which was sold on April 1, 2014, included in the three- and six-month periods ended April 30, 2014:

Product Sales

We produce a wide variety of products that are used in the fenestration industry, including: window and door systems design, engineering and fabrication; accessory trim profiles with real wood veneers and wood grain laminate finishes; window spacer systems; extruded vinyl products; metal fabrication; and astragals, thresholds and screens. In addition, we produce certain non-fenestration products, including: wood and aluminum grilles, flooring and trim moldings, solar edge tape and other products. Historically, we have presented product sales information at the reportable segment level, and we attribute our net sales based on the location of the customer. We have four operating segments that are aggregated into one reportable segment, which includes this breadth of product offerings across the fenestration and non-fenestration spectrum, but for which there are common economic and other characteristics that meet the criteria for aggregation.

ASC Topic 280-10-50, “Segment Reporting” (ASC 280) permits aggregation of operating segments based on factors including, but not limited to: (1) similar nature of products serving the building products industry, primarily the fenestration business; (2) similar production processes, although there are some differences in the amount of automation amongst operating plants; (3) similar types or classes of customers, namely the primary original equipment manufacturers (OEMs) in the window and door industry; (4) similar distribution methods for product delivery, although the extent of the use of third-party distributors will vary amongst the businesses; (5) similar regulatory environment; and (6) converging long-term economic similarities.

The following table summarizes our product sales for the three- and six-month periods ended April 30, 2015 and 2014 into general groupings to provide additional information to our shareholders.

Fair Value Measurement of Assets and Liabilities

Fair Value Disclosures [Abstract]

Fair Value Measurement of Assets and Liabilities

Fair Value Measurement of Assets and Liabilities

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity's own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to Level 1 and the lowest priority to Level 3. The three levels of the fair value hierarchy are described below:

• Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

• Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates) and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

• Level 3 - Inputs that are both significant to the fair value measurement and unobservable.

The following table summarizes the assets and liabilities measured on a recurring basis based on the fair value hierarchy (in thousands):

We held short-term investments (with an original maturity of three months or less) in commercial paper at April 30, 2015 and October 31, 2014. We have included these investments as cash and cash equivalents in the accompanying condensed consolidated balance sheets. These investments are measured at fair value based on active market quotations and are therefore classified as Level 1. All of our derivative contracts are valued using quoted market prices from brokers or exchanges and are classified within Level 2 of the fair value hierarchy.

We had approximately $2.4 million of certain property, plant and equipment that was recorded at fair value on a non-recurring basis and classified as Level 3 as of April 30, 2015 and October 31, 2014. The fair value was based on broker opinions.

Carrying amounts reported on the balance sheet for cash, cash equivalents, accounts receivable and accounts payable approximate fair value due to the short-term maturity of these instruments. Our outstanding debt was variable rate debt that re-prices frequently, thereby limiting our exposure to significant change in interest rate risk. As a result, the fair value of our debt instruments approximates carrying value at April 30, 2015 and October 31, 2014 (Level 3 measurement).
