Basis of Presentation	'
	NOTE A – Basis of Presentation
	The accompanying unaudited consolidated financial statements include the accounts of Worthington Industries, Inc. and consolidated subsidiaries (collectively, “we”, “our”, “Worthington” or the “Company”). Investments in unconsolidated affiliates are accounted for using the equity method. Significant intercompany accounts and transactions are eliminated.
	Spartan Steel Coating, LLC (“Spartan”), TWB Company, L.L.C. (“TWB”), Worthington Energy Innovations, LLC (“WEI”), and Worthington Nitin Cylinders Limited (“WNCL”) in which we own controlling interests of 52%, 55%, 75%, and 60%, respectively, are consolidated with the equity owned by the other joint venture members shown as noncontrolling interest in our consolidated balance sheets, and the other joint venture members’ portion of net earnings shown as net earnings attributable to noncontrolling interest in our consolidated statements of earnings. As more fully described in “NOTE M – Acquisitions,” on July 31, 2013, we purchased an additional 10% interest in TWB for $17,869,000, increasing our ownership to a 55% controlling interest. As a result, TWB’s results have been consolidated within the Steel Processing operating segment since the acquisition date.
	These unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments, which are of a normal and recurring nature, except those which have been disclosed elsewhere in this Quarterly Report on Form 10-Q, necessary for a fair presentation of the results of operations of these interim periods, have been included. Operating results for the three and six months ended November 30, 2013 are not necessarily indicative of the results that may be expected for the fiscal year ending May 31, 2014 (“fiscal 2014”). For further information, refer to the consolidated financial statements and notes thereto included in the Annual Report on Form 10-K for the fiscal year ended May 31, 2013 (“fiscal 2013”) of Worthington Industries, Inc. (the “2013 Form 10-K”).
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
	Joint Venture Transactions
	On March 1, 2011, we joined with ClarkWestern Building Systems Inc. to form Clarkwestern Dietrich Building Systems LLC (“ClarkDietrich”), a joint venture that manufactures a full line of drywall studs and accessories, structural studs and joists, metal lath and accessories, and shaft wall studs and track used primarily in residential and commercial construction. We contributed our metal framing business and related working capital in exchange for a 25% ownership interest in ClarkDietrich. As we do not have a controlling interest in ClarkDietrich, our investment in this joint venture is accounted for under the equity method, and the contributed net assets were deconsolidated effective March 1, 2011.
	We retained and continued to operate the remaining metal framing facilities (the “retained facilities”), on a short-term basis, to support the transition of the business into ClarkDietrich. The buildings and equipment associated with the majority of these facilities were sold during fiscal 2013 and fiscal 2012. The remaining facilities are expected to be sold during fiscal 2014 and actions to locate buyers are ongoing. As the other relevant criteria for classification as assets held for sale have been satisfied, the $2,435,000 carrying value of these asset groups, which consist primarily of property, plant and equipment, is presented separately in our consolidated balance sheet as of November 30, 2013.
	Recently Issued Accounting Standards
	In December 2011, new accounting guidance was issued that establishes certain additional disclosure requirements about financial instruments and derivatives instruments that are subject to netting arrangements. The new disclosures are required for annual reporting periods beginning on or after January 1, 2013, and interim periods within those periods. We adopted this new guidance on June 1, 2013, and have provided the required disclosures in “NOTE N – Derivative Instruments and Hedging Activities.”
	In June 2011, new accounting guidance was issued regarding the presentation of comprehensive income in financial statements prepared in accordance with U.S. GAAP. This new guidance requires entities to present reclassification adjustments included in other comprehensive income on the face of the financial statements and allows entities to present total comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. It also eliminates the option for entities to present the components of other comprehensive income as part of the statement of equity. For public companies, this accounting guidance was effective for fiscal years (and interim periods within those fiscal years) beginning after December 15, 2011, with early adoption permitted. Retrospective application to prior periods is required. We adopted the effective provisions of this new accounting guidance on June 1, 2012 and have provided the required statements of comprehensive income for the three and six months ended November 30, 2013 and 2012. In December 2011, certain provisions of this new guidance related to the presentation of reclassification adjustments out of accumulated other comprehensive income were temporarily deferred. In February 2013, an effective date was established for the provisions that had been deferred. These provisions are effective prospectively for annual reporting periods, and interim periods within those annual periods, beginning after December 15, 2012. We adopted the deferred provisions, which relate to presentation only, on June 1, 2013 and have provided the required disclosures in “NOTE G – Comprehensive Income.” There was no impact on our financial position or results of operations.
	In July 2012, amended accounting guidance was issued that simplifies how an entity tests indefinite-lived intangible assets for impairment. The amended guidance allows an entity to first assess qualitative factors to determine whether it is necessary to perform a quantitative impairment test. An entity will no longer be required to calculate the fair value of an indefinite-lived intangible asset and perform the quantitative test unless the entity determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The amended guidance is effective for interim and annual indefinite-lived intangible asset impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The adoption of this amended accounting guidance on June 1, 2013, did not have a material impact on our financial position or results of operations.
	In March 2013, amended accounting guidance was issued regarding the accounting for cumulative translation adjustment. The amended guidance specifies that a cumulative translation adjustment should be released from earnings when an entity ceases to have a controlling financial interest in a subsidiary or a group of assets within a consolidated foreign entity and the sale or transfer results in the complete or substantially complete liquidation of the foreign entity. For sales of an equity method investment that is a foreign entity, a pro rata portion of the cumulative translation adjustment attributable to the investment would be recognized in earnings upon sale of the investment. The amended guidance is effective prospectively for annual reporting periods, and interim periods within those annual periods, beginning after December 15, 2013. Early adoption is permitted. We do not expect the adoption of this amended accounting guidance to have a material impact on our financial position or results of operations.

Investments in Unconsolidated Affiliates	'
	NOTE B – Investments in Unconsolidated Affiliates
	Our investments in affiliated companies that we do not control, either through majority ownership or otherwise, are accounted for using the equity method. At November 30, 2013, these equity investments and the percentage interests owned consisted of: ArtiFlex Manufacturing, LLC (“ArtiFlex”) (50%), ClarkDietrich (25%), Samuel Steel Pickling Company (31.25%), Serviacero Planos, S. de R. L. de C.V. (50%), Worthington Armstrong Venture (“WAVE”) (50%), Worthington Modern Steel Framing Manufacturing Co., Ltd. (“WMSFMCo.”) (40%), and Worthington Specialty Processing (“WSP”) (51%). WSP is considered to be jointly controlled and not consolidated due to substantive participating rights of the minority partner.
	On July 31, 2013, we acquired an additional 10% interest in our laser welded blanks joint venture, TWB Company, L.L.C. (“TWB”), increasing our ownership to a 55% controlling interest. Since that date, TWB’s results have been consolidated within Steel Processing versus reported in equity in net income of unconsolidated affiliates. For additional information, refer to “NOTE M – Acquisitions.”
	On October 18, 2013, we finalized an agreement with Nisshin Steel Co., Ltd. and Marubeni-Itochu Steel Inc. to form Zhejiang Nisshin Worthington Precision Specialty Steel Co., Ltd., which is awaiting regulatory approval. Initially, we will own a 10% interest in the joint venture with the option to increase our ownership interest to 34%. The joint venture will construct a plant in Zhejiang Province in the People’s Republic of China that will produce cold rolled strip steel primarily for the automotive industry.
	During the second quarter of fiscal 2014, we dissolved our wind turbine joint venture, Gestamp Worthington Wind Steel, LLC, due to the volatile political environment in the United States, particularly in regards to the Federal Production Tax Credit. This event did not have a material impact on our financial position or results of operations.
	We received distributions from unconsolidated affiliates totaling $47,839,000 during the six months ended November 30, 2013. We have received cumulative distributions from WAVE in excess of our investment balance totaling $61,107,000 and $63,187,000 at November 30, 2013 and May 31, 2013, respectively. In accordance with the applicable accounting guidance, these excess distributions are reclassified to the liabilities section of our consolidated balance sheet. We will continue to record our equity in the net income of WAVE as a debit to the investment account, and if it becomes positive, it will again be shown as an asset on our consolidated balance sheet. If it becomes obvious that any excess distribution may not be returned (upon joint venture liquidation or otherwise), we will recognize any balance classified as a liability as income immediately.
	We use the “cumulative earnings” approach for determining cash flow presentation of distributions from our unconsolidated joint ventures. Distributions received are included in our consolidated statements of cash flows as operating activities, unless the cumulative distributions exceed our portion of the cumulative equity in the net earnings of the joint venture, in which case the excess distributions are deemed to be returns of the investment and are classified as investing activities in our consolidated statements of cash flows. During the three and six months ended November 30, 2013, we received excess distributions from ClarkDietrich of $3,668,000 and $9,223,000, respectively.

Restructuring and Other Expense (Income)	'
	NOTE C – Restructuring and Other Expense (Income)
	In fiscal 2008, we initiated a Transformation Plan (the “Transformation Plan”) with the overall goal to improve our sustainable earnings potential, asset utilization and operational performance. The Transformation Plan focuses on cost reduction, margin expansion and organizational capability improvements and, in the process, seeks to drive excellence in three core competencies: sales; operations; and supply chain management. The Transformation Plan is comprehensive in scope and includes aggressive diagnostic and implementation phases. When this process began, we retained a consulting firm to assist in the development and implementation of the Transformation Plan. As the Transformation Plan progressed, we formed internal teams dedicated to this effort, and they ultimately assumed full responsibility for executing the Transformation Plan. Although the consulting firm was again engaged as we rolled out the Transformation Plan in our Pressure Cylinders operating segment, most of the work is now being done by our internal teams. These internal teams are now an integral part of our business and constitute what we refer to as the Centers of Excellence (“COE”). The COE will continue to monitor the performance metrics and new processes instituted across our transformed operations and drive continuous improvements in all areas of our operations. The majority of the expenses related to the COE will be included in selling, general and administrative (“SG&A”) expense going forward, except where they relate to a first time diagnostics phase of the Transformation Plan.
	To date, we have completed the transformation phases in each of the core facilities within our Steel Processing operating segment, including the facilities of our Mexican joint venture. We also substantially completed the transformation phases at our metal framing facilities prior to their contribution to ClarkDietrich. Transformation efforts within our Pressure Cylinders and Engineered Cabs operating segments, which began during the first quarter of fiscal 2012 and the first quarter of fiscal 2013, respectively, are ongoing.
	A progression of the liabilities created as part of the Transformation Plan during the six months ended November 30, 2013, combined with a reconciliation to the restructuring and other expense (income) financial statement caption in our consolidated statement of earnings is summarized as follows:
	(in thousands)		Beginning		Expense			Payments			Adjustments			Ending
			Balance											Balance
	Early retirement and severance		$	5,029	$	4,292		$	(1,135	)	$	37		$	8,223

	Net gain on sale of assets					(10,701	)
	Less: joint venture transactions					(928	)
	Restructuring and other expense				$	(5,179	)
	During the six months ended November 30, 2013, the following actions were taken in connection with the Transformation Plan:
		•		In connection with the wind-down of our former Metal Framing operating segment, we recognized $928,000 of facility exit and other costs. These costs were recognized within the joint venture transactions financial statement caption in our consolidated statements of earnings to correspond with amounts previously recognized in connection with the formation of ClarkDietrich and the subsequent wind-down of our former Metal Framing operating segment.
		•		In connection with the closure of our commercial stairs business, we incurred facility exit charges of $1,030,000.
		•		In connection with the consolidation of the BernzOmatic hand torch manufacturing operation in Medina, New York into the existing Pressure Cylinders’ facility in Chilton, Wisconsin, we recognized an additional $578,000 accrual for expected employee severance costs. During the fourth quarter of fiscal 2013, we recognized a $2,488,000 accrual for expected severance costs related to this matter.
		•		On June 30, 2013, the Company completed the sale of Integrated Terminals, its warehouse facility in Detroit, Michigan, for cash proceeds of $7,457,000, resulting in a gain of $4,762,000.

Contingent Liabilities	'
	NOTE D – Contingent Liabilities
	On August 5, 2013, we tendered to our excess loss carrier, who accepted the tender, a wrongful death claim against the Company involving a MAPP gas cylinder. Pursuant to the tender and its acceptance, our overall exposure related to this matter is limited to $2,000,000. As a result, a pre-tax charge of $2,000,000 was recorded within SG&A expense during the six months ended November 20, 2013.
	We are defendants in certain legal actions. In the opinion of management, the outcome of these actions, which is not clearly determinable at the present time, would not significantly affect our consolidated financial position or future results of operations. We believe that environmental issues will not have a material effect on our capital expenditures, consolidated financial position or future results of operations.
	Insurance Recoveries
	On August 19, 2013, a fire occurred at our Pressure Cylinders facility in Kienberg, Austria, in the building that houses the massing process in the production of acetylene cylinders. The other portions of the Austrian facility were not damaged; however, the massing building sustained extensive damage and was rendered inoperable. We have incurred losses related to the destruction of assets caused by the fire. Additionally, we have incurred and will continue to incur incremental business interruption costs. The Company has business interruption and property damage insurance and, as a result, the fire did not have a material adverse impact on the Company’s financial results.
	During the second quarter of fiscal 2014, the Company received proceeds of $2,623,000 for the property portion of the claim, representing advance payments for the replacement value of the damaged property and equipment. These proceeds were in excess of the $145,000 remaining book value of the assets, resulting in a gain of $2,478,000. This gain was recorded within miscellaneous income in our consolidated statement of earnings for the six months ended November 30, 2013. We will continue to receive payments from the insurance company for the replacement value of the property and equipment throughout the rebuild process.
	Total proceeds received related to the insurance claim since the date of loss were as follows:
	(in thousands)
	Property and equipment	$	2,623
	Business interruption		676
	Other expenses		267
	Total insurance proceeds	$	3,566
	The proceeds for business interruption relate to the loss of profits from the date of the fire through October 31, 2013, and have been recorded as a reduction of manufacturing expense. The proceeds for other expenses represent reimbursement for incremental expenses related to the fire and were recorded as an offset to manufacturing expense.

Guarantees

Guarantees	'
	NOTE E – Guarantees
	We do not have guarantees that we believe are reasonably likely to have a material current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources. However, as of November 30, 2013, we were party to an operating lease for an aircraft in which we have guaranteed a residual value at the termination of the lease. The maximum obligation under the terms of this guarantee was approximately $13,459,000 at November 30, 2013. We have also guaranteed the repayment of a term loan entered into by one of our unconsolidated affiliates, ArtiFlex. As of November 30, 2013, the outstanding principal balance on the loan was $4,167,000. Based on current facts and circumstances, we have estimated the likelihood of payment pursuant to these guarantees, and determined that the fair value of our obligation under each guarantee based on those likely outcomes is not material and therefore no amounts have been recognized in our consolidated financial statements.
	We also had in place $11,732,000 of outstanding stand-by letters of credit for third-party beneficiaries as of November 30, 2013. These letters of credit were issued to third-party service providers and had no amounts drawn against them at November 30, 2013. The fair value of these guarantee instruments, based on premiums paid, was not material, and therefore no amounts have been recognized in our consolidated financial statements.

Debt and Receivables Securitization	'
	NOTE F – Debt and Receivables Securitization
	We have a $425,000,000 multi-year revolving credit facility (the “Credit Facility”) with a group of lenders that matures in May 2017. Borrowings outstanding under the Credit Facility were $8,440,000 at November 30, 2013. Additionally, as discussed in “NOTE E – Guarantees,” we provided $11,732,000 in stand-by letters of credit for third-party beneficiaries as of November 30, 2013. While not drawn against, these letters of credit are issued against availability under the Credit Facility, leaving $404,828,000 available at November 30, 2013.
	Current borrowings under this revolving Credit Facility have maturities of less than one year, and given that we intend to repay them within the next year, they have been classified as short-term borrowings in our consolidated balance sheet. However, we can extend the term of amounts borrowed by renewing these borrowings for the term of the Credit Facility. We have the option to borrow at rates equal to an applicable margin over the LIBOR, Prime or Fed Funds rates. The applicable margin is determined by our credit rating. At November 30, 2013, the applicable variable rate, based on LIBOR, was 1.22%.
	We also maintain a $100,000,000 revolving trade accounts receivable securitization facility (the “AR Facility”), which expires in January 2015. The AR Facility has been available throughout fiscal 2014 to date, and was available throughout fiscal 2013. Pursuant to the terms of the AR Facility, certain of our subsidiaries sell their accounts receivable without recourse, on a revolving basis, to Worthington Receivables Corporation (“WRC”), a wholly-owned, consolidated, bankruptcy-remote subsidiary. In turn, WRC may sell without recourse, on a revolving basis, up to $100,000,000 of undivided ownership interests in this pool of accounts receivable to a third-party bank. We retain an undivided interest in this pool and are subject to risk of loss based on the collectability of the receivables from this retained interest. Because the amount eligible to be sold excludes receivables more than 90 days past due, receivables offset by an allowance for doubtful accounts due to bankruptcy or other cause, concentrations over certain limits with specific customers and certain reserve amounts, we believe additional risk of loss is minimal. The book value of the retained portion of the pool of accounts receivable approximates fair value. As of November 30, 2013, the pool of eligible accounts receivable exceeded the $100,000,000 limit, and $30,000,000 of undivided ownership interests in this pool of accounts receivable had been sold.
	The remaining balance of short-term borrowings at November 30, 2013 consisted of $5,011,000 outstanding under a $9,500,000 credit facility maintained by our consolidated affiliate, WNCL. This credit facility matures in November 2014 and bears interest at a variable rate. The applicable variable rate was 2.25% at November 30, 2013.

Stock-Based Compensation	'
	NOTE I – Stock-Based Compensation
	Non-Qualified Stock Options
	During the six months ended November 30, 2013, we granted non-qualified stock options covering a total of 125,200 common shares under our stock-based compensation plans. The weighted average option price of $31.89 per share reflects the market price of the underlying common shares at the grant date. The weighted average fair value of these stock options, based on the Black-Scholes option-pricing model, calculated at the grant date, was $12.92 per share. The calculated pre-tax stock-based compensation expense for these stock options, after an estimate for forfeitures, is $1,482,000, which will be recognized on a straight-line basis over the three-year vesting period. The following assumptions were used to value these stock options:
	Dividend yield	2.28	%
	Expected volatility	52.23	%
	Risk-free interest rate	1.69	%
	Expected term (years)	6
	Expected volatility is based on the historical volatility of our common shares and the risk-free interest rate is based on the United States Treasury strip rate for the expected term of the stock options. The expected term was developed using historical exercise experience.
	Restricted Common Shares
	During the six months ended November 30, 2013, we granted 369,140 restricted common shares under our stock-based compensation plans. The fair values of these restricted common shares were equal to the weighted average closing market prices of the underlying common shares on the date of grant, or $32.96 per share. The calculated pre-tax stock-based compensation expense for these restricted common shares, after an estimate for forfeitures, is $10,931,000 and will be recognized on a straight-line basis over the three-year vesting period.
	Market-Based Restricted Common Shares
	During the six months ended November 30, 2013, we granted 360,000 restricted common shares to certain key employees under our stock-based compensation plans. Vesting of these restricted common share awards is contingent upon the price of our common shares reaching $50.00 per share and remaining at or above that price for 30 consecutive days and the completion of a three-year service vesting period. The grant-date fair value of these restricted common shares, as determined by a Monte Carlo simulation model, was $24.19 per share. The Monte Carlo simulation model is a statistical technique that incorporates multiple assumptions to determine the probability that the market condition will be achieved. The following assumptions were used to determine the grant-date fair value and the derived service period for these restricted common shares:
	Dividend yield	2.28	%
	Expected volatility	53.4	%
	Risk-free interest rate	1.41	%
	The calculated pre-tax stock-based compensation expense for these restricted common shares was determined to be $8,708,000 and will be recognized on a straight-line basis over the three-year service vesting period.

Income Taxes	'
	NOTE J – Income Taxes
	Income tax expense for the six months ended November 30, 2013 and November 30, 2012 reflected estimated annual effective income tax rates of 27.8% and 32.7%, respectively. The annual effective income tax rates exclude any impact from the inclusion of net earnings attributable to non-controlling interests in our consolidated statements of earnings. Net earnings attributable to noncontrolling interest is primarily a result of our Spartan and TWB consolidated joint ventures. The earnings attributable to the noncontrolling interest in Spartan and TWB’s U.S. operations do not generate tax expense to Worthington since the investors in Spartan and TWB’s U.S. operations are taxed directly based on the earnings attributable to them. Since the consolidation of TWB on July 31, 2013, 100% of the tax expense of TWB’s foreign operations has been included in the Company’s reported income tax expense for financial reporting purposes, and is therefore included in the estimated annual effective income tax rate. For additional information regarding the consolidation of TWB, refer to “NOTE M – Acquisitions.” Management is required to estimate the annual effective income tax rate based upon its forecast of annual pre-tax income for domestic and foreign operations. Our actual effective income tax rate for fiscal 2014 could be materially different from the forecasted rate as of November 30, 2013.

	On July 31, 2013, we purchased an additional 10% interest in our laser welded blanks joint venture, TWB, for $17,869,000, increasing our ownership to a 55% controlling interest. This transaction was accounted for as a step acquisition, which required that we re-measure our previously held 45% ownership interest to fair value and record the difference between fair value and carrying value as a gain in our consolidated statement of earnings. The re-measurement to fair value resulted in a non-cash pre-tax gain of $11,000,000, which is included in miscellaneous income in our consolidated statement of earnings for the six months ended November 30, 2013. The acquired net assets became part of our Steel Processing operating segment upon closing.
	The assets acquired and liabilities assumed were recognized at their acquisition-date fair values. In connection with the acquisition of TWB, we identified and valued the following identifiable intangible assets:

	Total acquired identifiable intangible assets	$	22,028
	The estimated fair value of the assets acquired and liabilities assumed approximated the purchase price and therefore no goodwill was recognized.
	The following table summarizes the consideration transferred for our 55% controlling interest in TWB and the fair value assigned to the assets acquired and liabilities assumed at the acquisition date:

	The fair value of our previously held equity interest and the noncontrolling interest was derived using a market approach, and included a minority discount of 10% to reflect management’s estimate of the control premium.
	Operating results of TWB have been included in our consolidated statements of earnings from the acquisition date, forward. For periods prior to the acquisition date, our portion of the equity in the net income of TWB was included within equity in net income of unconsolidated affiliates in our consolidated statements of earnings. Pro forma results, including the acquired business since the beginning of fiscal 2013, would not be materially different than reported results.

Derivative Instruments and Hedging Activities	'
	NOTE N – Derivative Instruments and Hedging Activities
	We utilize derivative financial instruments to manage exposure to certain risks related to our ongoing operations. The primary risks managed through the use of derivative instruments include interest rate risk, currency exchange risk and commodity price risk. While certain of our derivative instruments are designated as hedging instruments, we also enter into derivative instruments that are designed to hedge a risk, but are not designated as hedging instruments and therefore do not qualify for hedge accounting. These derivative instruments are adjusted to current fair value through earnings at the end of each period.
	Interest Rate Risk Management – We are exposed to the impact of interest rate changes. Our objective is to manage the impact of interest rate changes on cash flows and the market value of our borrowings. We utilize a mix of debt maturities along with both fixed-rate and variable-rate debt to manage changes in interest rates. In addition, we enter into interest rate swaps to further manage our exposure to interest rate variations related to our borrowings and to lower our overall borrowing costs.
	Currency Exchange Risk Management – We conduct business in several major international currencies and are therefore subject to risks associated with changing foreign exchange rates. We enter into various contracts that change in value as foreign exchange rates change to manage this exposure. Such contracts limit exposure to both favorable and unfavorable currency fluctuations. The translation of foreign currencies into United States dollars also subjects us to exposure related to fluctuating exchange rates; however, derivative instruments are not used to manage this risk.
	Commodity Price Risk Management – We are exposed to changes in the price of certain commodities, including steel, natural gas, zinc and other raw materials, and our utility requirements. Our objective is to reduce earnings and cash flow volatility associated with forecasted purchases and sales of these commodities to allow management to focus its attention on business operations. Accordingly, we enter into derivative instruments to manage the associated price risk.
	We are exposed to counterparty credit risk on all of our derivative instruments. Accordingly, we have established and maintain strict counterparty credit guidelines and enter into derivative instruments only with major financial institutions. We do not have significant exposure to any one counterparty and management believes the risk of loss is remote and, in any event, would not be material.
	Refer to “Note O – Fair Value” for additional information regarding the accounting treatment for our derivative instruments, as well as how fair value is determined.

	Cash Flow Hedges
	We enter into derivative instruments to hedge our exposure to changes in cash flows attributable to interest rate and commodity price fluctuations associated with certain forecasted transactions. These derivative instruments are designated and qualify as cash flow hedges. Accordingly, the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income (“OCI”) and reclassified into earnings in the same line item associated with the forecasted transaction and in the same period during which the hedged transaction affects earnings. The ineffective portion of the gain or loss on the derivative instrument is recognized in earnings immediately.
	The following table summarizes our cash flow hedges outstanding at November 30, 2013:

The estimated net amount of the losses recognized in accumulated OCI at November 30, 2013 expected to be reclassified into net earnings within the succeeding twelve months is $1,274,000 (net of tax of $718,000). This amount was computed using the fair value of the cash flow hedges at November 30, 2013, and will change before actual reclassification from OCI to net earnings during the fiscal years ending May 31, 2014 and 2015.
Economic (Non-designated) Hedges
We enter into foreign currency contracts to manage our foreign exchange exposure related to inter-company and financing transactions that do not meet the requirements for hedge accounting treatment. We also enter into certain commodity contracts that do not qualify for hedge accounting treatment. Accordingly, these derivative instruments are adjusted to current market value at the end of each period through earnings.

Fair Value	'
	NOTE O – Fair Value
	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. Fair value is an exit price concept that assumes an orderly transaction between willing market participants and is required to be based on assumptions that market participants would use in pricing an asset or a liability. Current accounting guidance establishes a three-tier fair value hierarchy as a basis for considering such assumptions and for classifying the inputs used in the valuation methodologies. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair values are as follows:
	Level 1		–		Observable prices in active markets for identical assets and liabilities.
	Level 2		–		Observable inputs other than quoted prices in active markets for identical assets and liabilities.
	Level 3		–		Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities.
	Recurring Fair Value Measurements
	At November 30, 2013, our financial assets and liabilities measured at fair value on a recurring basis were as follows:

	-1	During the first quarter of fiscal 2014, we determined that certain indicators of impairment were present with regard to certain non-core Steel Processing assets. Recoverability of the identified asset group was tested using future cash flow projections based on management’s estimate of market conditions. The sum of these undiscounted future cash flows was less than the net book value of the asset group. The net book value was also determined to be in excess of fair value and, accordingly, the asset group was written down to its fair value of $11,827,000, resulting in an impairment charge of $4,641,000. Fair value was determined based on market prices for similar assets.
	-2	During the second quarter of fiscal 2014, we committed to a re-branding initiative. Under the re-branding initiative, we will re-brand substantially all of our businesses under the Worthington Industries name. In connection with the change in branding strategy, we plan to discontinue the use of all non-Worthington trade names except those related to products such as BernzOmatic® and Balloon Time® and those related to our joint ventures. As no future cash flows will be attributed to the impacted trade names, the entire book value was written-off, resulting in an impairment charge of $30,734,000. Fair value was determined using unobservable (Level 3) inputs.
	At May 31, 2013, our assets measured at fair value on a non-recurring basis were categorized as follows:

This impairment loss was recorded within impairment of long-lived assets in our consolidated statement of earnings. The portion of this impairment loss attributable to the noncontrolling interest, or $1,987,000, is recorded within net earnings attributable to noncontrolling interest in our consolidated statement of earnings. Fair value was determined based on market prices for similar assets.
	The fair value of our foreign currency contracts, commodity contracts and interest rate contracts is based on the present value of the expected future cash flows considering the risks involved, including non-performance risk, and using discount rates appropriate for the respective maturities. Market observable, Level 2 inputs are used to determine the present value of the expected future cash flows. Refer to “NOTE N – Derivative Instruments and Hedging Activities” for additional information regarding our use of derivative instruments.
	The fair value included in the carrying amounts of cash and cash equivalents, receivables, income taxes receivable, other assets, deferred income taxes, accounts payable, short-term borrowings, accrued compensation, contributions to employee benefit plans and related taxes, other accrued items, income taxes payable and other liabilities approximate carrying value due to their short-term nature. The fair value of long-term debt, including current maturities, based upon models utilizing market observable (Level 2) inputs and credit risk, was $394,003,000 and $421,056,000 at November 30, 2013 and May 31, 2013, respectively. The carrying amount of long-term debt, including current maturities, was $406,767,000 and $407,328,000 at November 30, 2013 and May 31, 2013, respectively.

	NOTE P – Subsequent Events
	On December 10, 2013, the Company announced to its employees that its Baltimore steel facility will be closing by the end of fiscal 2014. With the consolidation of the steel industry, many of the mills that previously supplied the Baltimore facility have closed, negatively impacting the supply chain there. The Company has concluded that it can more efficiently service its customers in the Mid-Atlantic Region from other Worthington facilities and processing partners, and believes it will retain most of the business.
	Production at Baltimore will wind down over the coming months. Employees there will have the opportunity to apply for job openings at other Worthington facilities. For employees who will not continue with the Company, severance and outplacement services will be provided.
	The Company does not expect the net effect from the wind down and closure of the Baltimore facility to have a material impact on its financial position or results of operation.
	On January 6, 2014, the Company announced that its Pressure Cylinders operating segment signed an agreement to acquire a 75% interest in ARITAS, one of Europe’s leading liquefied natural gas (“LNG”) and cryogenic technology companies. ARITAS offers a broad portfolio of LNG products, cryogenic vessels, systems and services and is located in Istanbul, Turkey. The transaction is awaiting Turkish government approval, which is expected to be completed later this month.

	Recently Issued Accounting Standards
	In December 2011, new accounting guidance was issued that establishes certain additional disclosure requirements about financial instruments and derivatives instruments that are subject to netting arrangements. The new disclosures are required for annual reporting periods beginning on or after January 1, 2013, and interim periods within those periods. We adopted this new guidance on June 1, 2013, and have provided the required disclosures in “NOTE N – Derivative Instruments and Hedging Activities.”
	In June 2011, new accounting guidance was issued regarding the presentation of comprehensive income in financial statements prepared in accordance with U.S. GAAP. This new guidance requires entities to present reclassification adjustments included in other comprehensive income on the face of the financial statements and allows entities to present total comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. It also eliminates the option for entities to present the components of other comprehensive income as part of the statement of equity. For public companies, this accounting guidance was effective for fiscal years (and interim periods within those fiscal years) beginning after December 15, 2011, with early adoption permitted. Retrospective application to prior periods is required. We adopted the effective provisions of this new accounting guidance on June 1, 2012 and have provided the required statements of comprehensive income for the three and six months ended November 30, 2013 and 2012. In December 2011, certain provisions of this new guidance related to the presentation of reclassification adjustments out of accumulated other comprehensive income were temporarily deferred. In February 2013, an effective date was established for the provisions that had been deferred. These provisions are effective prospectively for annual reporting periods, and interim periods within those annual periods, beginning after December 15, 2012. We adopted the deferred provisions, which relate to presentation only, on June 1, 2013 and have provided the required disclosures in “NOTE G – Comprehensive Income.” There was no impact on our financial position or results of operations.
	In July 2012, amended accounting guidance was issued that simplifies how an entity tests indefinite-lived intangible assets for impairment. The amended guidance allows an entity to first assess qualitative factors to determine whether it is necessary to perform a quantitative impairment test. An entity will no longer be required to calculate the fair value of an indefinite-lived intangible asset and perform the quantitative test unless the entity determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The amended guidance is effective for interim and annual indefinite-lived intangible asset impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The adoption of this amended accounting guidance on June 1, 2013, did not have a material impact on our financial position or results of operations.
	In March 2013, amended accounting guidance was issued regarding the accounting for cumulative translation adjustment. The amended guidance specifies that a cumulative translation adjustment should be released from earnings when an entity ceases to have a controlling financial interest in a subsidiary or a group of assets within a consolidated foreign entity and the sale or transfer results in the complete or substantially complete liquidation of the foreign entity. For sales of an equity method investment that is a foreign entity, a pro rata portion of the cumulative translation adjustment attributable to the investment would be recognized in earnings upon sale of the investment. The amended guidance is effective prospectively for annual reporting periods, and interim periods within those annual periods, beginning after December 15, 2013. Early adoption is permitted. We do not expect the adoption of this amended accounting guidance to have a material impact on our financial position or results of operations.

	-1	During the first quarter of fiscal 2014, we determined that certain indicators of impairment were present with regard to certain non-core Steel Processing assets. Recoverability of the identified asset group was tested using future cash flow projections based on management’s estimate of market conditions. The sum of these undiscounted future cash flows was less than the net book value of the asset group. The net book value was also determined to be in excess of fair value and, accordingly, the asset group was written down to its fair value of $11,827,000, resulting in an impairment charge of $4,641,000. Fair value was determined based on market prices for similar assets.
	-2	During the second quarter of fiscal 2014, we committed to a re-branding initiative. Under the re-branding initiative, we will re-brand substantially all of our businesses under the Worthington Industries name. In connection with the change in branding strategy, we plan to discontinue the use of all non-Worthington trade names except those related to products such as BernzOmatic® and Balloon Time® and those related to our joint ventures. As no future cash flows will be attributed to the impacted trade names, the entire book value was written-off, resulting in an impairment charge of $30,734,000. Fair value was determined using unobservable (Level 3) inputs.
	At May 31, 2013, our assets measured at fair value on a non-recurring basis were categorized as follows:

This impairment loss was recorded within impairment of long-lived assets in our consolidated statement of earnings. The portion of this impairment loss attributable to the noncontrolling interest, or $1,987,000, is recorded within net earnings attributable to noncontrolling interest in our consolidated statement of earnings. Fair value was determined based on market prices for similar assets.

[1]	During the first quarter of fiscal 2014, we determined that certain indicators of impairment were present with regard to certain non-core Steel Processing assets. Recoverability of the identified asset group was tested using future cash flow projections based on management's estimate of market conditions. The sum of these undiscounted future cash flows was less than the net book value of the asset group. The net book value was also determined to be in excess of fair value and, accordingly, the asset group was written down to its fair value of $11,827,000, resulting in an impairment charge of $4,641,000. Fair value was determined based on market prices for similar assets.
[2]	During the second quarter of fiscal 2014, we committed to a re-branding initiative. Under the re-branding initiative, we will re-brand substantially all of our businesses under the Worthington Industries name. In connection with the change in branding strategy, we plan to discontinue the use of all non-Worthington trade names except those related to products such as BernzOmaticB. and Balloon TimeB. and those related to our joint ventures. As no future cash flows will be attributed to the impacted trade names, the entire book value was written-off, resulting in an impairment charge of $30,734,000. Fair value was determined using unobservable (Level 3) inputs.
[3]	During the fourth quarter of fiscal 2013, the long-lived assets of our 60%-owned consolidated joint venture in India, WNCL, were written down to their fair value of $6,856,000, resulting in an impairment charge of $4,968,000. This impairment loss was recorded within impairment of long-lived assets in our consolidated statement of earnings. The portion of this impairment loss attributable to the noncontrolling interest, or $1,987,000, is recorded within net earnings attributable to noncontrolling interest in our consolidated statement of earnings. Fair value was determined based on market prices for similar assets.
