SAFE HARBOR STATEMENT

Selected statements contained in this Quarterly Report on Form 10-Q, including, without limitation, in “PART I – Item 2. – Management’s Discussion and Analysis of Financial Condition and Results of Operations,” constitute “forward-looking statements” as that term is used in the Private Securities Litigation Reform Act of 1995 (the “Act”). Forward-looking statements reflect our current expectations, estimates or projections concerning future results or events. These statements are often identified by the use of forward-looking words or phrases such as “believe,” “expect,” “anticipate,” “may,” “could,” “intend,” “estimate,” “plan,” “foresee,” “likely,” “will,” “should” or other similar words or phrases. These forward-looking statements include, without limitation, statements relating to:

• outlook, strategy or business plans;

• future or expected growth, growth potential, forward momentum, performance, competitive position, sales, volumes, cash flows, earnings, balance sheet strengths, debt, financial condition or other financial measures;

• pricing trends for raw materials and finished goods and the impact of pricing changes;

• demand trends for us or our markets;

• additions to product lines and opportunities to participate in new markets;

• expected benefits from Transformation and innovation efforts and the ability to improve performance and competitive position at our operations;

• anticipated working capital needs, capital expenditures and asset sales;

• anticipated improvements and efficiencies in costs, operations, sales, inventory management, sourcing and the supply chain and the results thereof;

• projected profitability potential;

• the ability to successfully integrate AMTROL and the expected benefits, costs and results from the acquisition of AMTROL;

• the ability to make acquisitions and the projected timing, results, benefits, costs, charges and expenditures related to acquisitions, newly-created joint ventures, headcount reductions and facility dispositions, shutdowns and consolidations;

• projected capacity and the alignment of operations with demand;

• the ability to operate profitably and generate cash in down markets;

• the ability to maintain margins and capture and maintain market share and to develop or take advantage of future opportunities, customer initiatives, new businesses, new products and new markets;

• expectations for Company and customer inventories, jobs and orders;

• expectations for the economy and markets or improvements therein;

• expectations for generating improving and sustainable earnings, earnings potential, margins or shareholder value;

• effects of judicial rulings; and

• other non-historical matters.

Because they are based on beliefs, estimates and assumptions, forward-looking statements are inherently subject to risks and uncertainties that could cause actual results to differ materially from those projected. Any number of factors could affect actual results, including, without limitation, those that follow:

• the effect of national, regional and global economic conditions generally and within major product markets, including a recurrent slowing economy;

• the effect of conditions in national and worldwide financial markets;

• lower oil prices as a factor in demand for products;

• product demand and pricing;

• changes in product mix, product substitution and market acceptance of our products;

• fluctuations in the pricing, quality or availability of raw materials (particularly steel), supplies, transportation, utilities and other items required by operations;

• effects of facility closures and the consolidation of operations;

• the effect of financial difficulties, consolidation and other changes within the steel, automotive, construction, oil and gas, and other industries in which we participate;

• failure to maintain appropriate levels of inventories;

• financial difficulties (including bankruptcy filings) of original equipment manufacturers, end-users and customers, suppliers, joint venture partners and others with whom we do business;

• the ability to realize targeted expense reductions from headcount reductions, facility closures and other cost reduction efforts;

ii

• the ability to realize cost savings and operational, sales and sourcing improvements and efficiencies, and other expected benefits from Transformation initiatives, on a timely basis;

• the overall success of, and the ability to integrate, newly-acquired businesses and joint ventures, maintain and develop their customers, and achieve synergies and other expected benefits and cost savings therefrom;

• capacity levels and efficiencies, within facilities, within major product markets and within the industries as a whole;

• the effect of disruption in the business of suppliers, customers, facilities and shipping operations due to adverse weather, casualty events, equipment breakdowns, civil unrest, international conflicts, terrorist activities or other causes;

• changes in customer demand, inventories, spending patterns, product choices, and supplier choices;

• risks associated with doing business internationally, including economic, political and social instability, foreign currency exchange rate exposure and the acceptance of our products in global markets;

• the ability to improve and maintain processes and business practices to keep pace with the economic, competitive and technological environment;

• the outcome of adverse claims experience with respect to workers’ compensation, product recalls or product liability, casualty events or other matters;

• deviation of actual results from estimates and/or assumptions used by us in the application of our critical accounting policies;

• level of imports and import prices in our markets;

• the impact of judicial rulings and governmental regulations, both in the United States and abroad, including those adopted by the United States Securities and Exchange Commission and other governmental agencies as contemplated by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010;

• the effect of healthcare laws in the United States and potential changes for such laws which may increase our healthcare and other costs and negatively impact our operations and financial results;

• cyber security risks; and

• other risks described from time to time in the filings of Worthington Industries, Inc. with the United States Securities and Exchange Commission, including those described in “PART I – Item 1A. — Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended May 31, 2017.

We note these factors for investors as contemplated by the Act. It is impossible to predict or identify all potential risk factors. Consequently, you should not consider the foregoing list to be a complete set of all potential risks and uncertainties. Any forward-looking statements in this Quarterly Report on Form 10-Q are based on current information as of the date of this Quarterly Report on Form 10-Q, and we assume no obligation to correct or update any such statements in the future, except as required by applicable law.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE A – Basis of Presentation

The 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.

The Company owns controlling interests in the following five joint ventures: Spartan Steel Coating, LLC (“Spartan”) (52%), TWB Company, L.L.C. (“TWB”) (55%), Worthington Aritaş Basinçli Kaplar Sanayi (“Worthington Aritas”) (75%), Worthington Energy Innovations, LLC (“WEI”) (75%), and Worthington Specialty Processing (“WSP”) (51%). These joint ventures are consolidated with the equity owned by the other joint venture members shown as noncontrolling interests in our consolidated balance sheets, and their portions of net earnings and other comprehensive income (loss) (“OCI”) shown as net earnings or comprehensive income attributable to noncontrolling interests in our consolidated statements of earnings and consolidated statements of comprehensive income, respectively.

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 consolidated financial statements for these interim periods, have been included. Operating results for the three months ended August 31, 2017 are not necessarily indicative of the results that may be expected for the fiscal year ending May 31, 2018 (“fiscal 2018”). 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, 2017 (“fiscal 2017”) of Worthington Industries, Inc. (the “2017 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 consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Recently Adopted Accounting Standards

In July 2015, amended accounting guidance was issued regarding the measurement of inventory. The amended guidance requires that inventory accounted for under the first-in, first-out (FIFO) or average cost methods be measured at the lower of cost and net realizable value, where net realizable value represents the estimated selling price of inventory in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The amended guidance has no impact on inventory accounted for under the last-in, first-out (LIFO) or retail inventory methods. The Company adopted this amended guidance on a prospective basis effective June 1, 2017. The adoption of this guidance did not impact our consolidated financial position or results of operations.

Recently Issued Accounting Standards

In May 2014, new accounting guidance was issued that replaces most existing revenue recognition guidance under U.S. GAAP. The new guidance requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. Subsequently, additional guidance was issued on several areas including guidance intended to improve the operability and understandability of the implementation of principal versus agent considerations and clarifications on the identification of performance obligations and implementation of guidance related to licensing. The new guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The guidance permits the use of either the retrospective or cumulative effect transition method. We are in the process of evaluating the effect this guidance will have on the presentation of our consolidated financial statements and related disclosures. While we have not yet identified any material changes in the timing of revenue recognition, our evaluation is ongoing and not complete. We plan to adopt the new guidance in the first quarter of fiscal 2019. The Company will continue to monitor any modifications, clarifications, and interpretations by the FASB that may impact its conclusions.

5

In February 2016, new accounting guidance was issued that replaces most existing lease accounting guidance under U.S. GAAP. Among other changes, the new guidance requires that lease assets and liabilities be recognized on the balance sheet by lessees for those leases classified as operating leases under previous guidance. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted, and the change is to be applied using a modified retrospective approach as of the beginning of the earliest period presented. We are in the process of evaluating the effect this guidance will have on our consolidated financial position, results of operations and cash flows, and we have not determined the effect of the new guidance on our ongoing financial reporting.

In June 2016, new accounting guidance was issued related to the measurement of credit losses on financial instruments. The new guidance changes the impairment model for most financial assets to require measurement and recognition of expected credit losses for financial assets held. The new guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and we have not determined the effect of the new guidance on our ongoing financial reporting.

In August 2016, amended accounting guidance was issued to clarify the proper cash flow presentation of certain specific types of cash payments and cash receipts. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position, results of operations and cash flows, and we have not determined the effect of the amended guidance on our ongoing financial reporting.

In October 2016, amended accounting guidance was issued that requires the income tax consequences of an intra-entity transfer of an asset other than inventory to be recognized when the transfer occurs. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position, results of operations and cash flows, and have not determined the effect of the amended guidance on our ongoing financial reporting.

In November 2016, amended accounting guidance was issued that requires amounts generally described as restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a material impact on our consolidated cash flows.

In January 2017, amended accounting guidance was issued to clarify the definition of a business to provide additional guidance to assist in evaluating whether transactions should be accounted for as an acquisition (or disposal) of either an asset or business. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a material impact on our consolidated financial position or results of operations.

In January 2017, amended accounting guidance was issued to simplify the goodwill impairment calculation, by removing Step 2 of the goodwill impairment test. Goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of the goodwill. The amended guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and have not determined the effect on our ongoing financial reporting.

6

In March 2017, amended accounting guidance was issued that requires an employer to report the service cost component of pension and postretirement benefits in the same line as other current employee compensation costs. Additionally, other components of net benefit cost are to be presented in the income statement separately from the service cost component and outside of income from operations. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and have not determined the effect on our ongoing financial reporting.

In May 2017, amended accounting guidance was issued to provide guidance about which changes to the terms or conditions of a share-based payment award require application of modification accounting. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a material impact on our consolidated financial position or results of operations.

In August 2017, amended accounting guidance was issued that modifies hedge accounting by making more hedge strategies eligible for hedge accounting, amending presentation and disclosure requirements, and changing how companies assess effectiveness. The intent is to simplify application of hedge accounting and increase transparency of information about an entity’s risk management activities. The amended guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and have not determined the effect on our ongoing financial reporting.

NOTE B – Investments in Unconsolidated Affiliates

Investments in affiliated companies that we do not control, either through majority ownership or otherwise, are accounted for using the equity method. These include ArtiFlex Manufacturing, LLC (“ArtiFlex”) (50%), Clarkwestern Dietrich Building Systems LLC (“ClarkDietrich”) (25%), Samuel Steel Pickling Company (31.25%), Serviacero Planos, S. de R. L. de C.V. (“Serviacero”) (50%), Worthington Armstrong Venture (“WAVE”) (50%), and Zhejiang Nisshin Worthington Precision Specialty Steel Co., Ltd. (10%).

We received distributions from unconsolidated affiliates totaling $19,551,000 during the three months ended August 31, 2017. We have received cumulative distributions from WAVE in excess of our investment balance, which resulted in an amount recorded within other liabilities on our consolidated balance sheets of $58,371,000 at August 31, 2017. In accordance with the applicable accounting guidance, we reclassified the negative balance 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 probable 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 received, less distributions received in prior periods that were determined to be returns of investment, 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.

NOTE C – Restructuring and Other Expense

We consider restructuring activities to be programs whereby we fundamentally change our operations such as closing and consolidating manufacturing facilities or moving manufacturing of a product to another location. Restructuring activities may also involve substantial realignment of the management structure of a business unit in response to changing market conditions.

A progression of the liabilities associated with our restructuring activities, combined with a reconciliation to the restructuring and other expense financial statement caption, in our consolidated statement of earnings for the three months ended August 31, 2017 is summarized below:

(in thousands)	Beginning Balance		Expense		Payments			Adjustments		Ending Balance
Early retirement and severance	$	253	$	1,877	$	(182	)	$	127	$	2,075
Facility exit and other costs		536		284		(950	)		131		1

During the three months ended August 31, 2017, the following actions were taken related to the Company’s restructuring activities:

• In connection with the acquisition of Amtrol on June 2, 2017, the Company recognized severance expense of $1,877,000 related to corporate management positions at Amtrol that were eliminated.

• In connection with the closure of the Company’s stainless steel business, Precision Specialty Metals, Inc. (“PSM”), the Company recognized facility exit costs of $279,000.

• In connection with other non-significant restructuring activities, the Company recognized facility exit costs of $5,000. The Company also recognized a net loss on disposal of assets of $143,000.

The total liability associated with our restructuring activities as of August 31, 2017 is expected to be paid in the next twelve months.

NOTE D – Contingent Liabilities and Commitments

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 have a material adverse effect on our consolidated financial position or future results of operations or cash flows. We believe that environmental issues will not have a material effect on our capital expenditures, consolidated financial position or future results of operations or cash flows.

NOTE E – Guarantees

We do not have guarantees that we believe are reasonably likely to have a material current or future effect on our consolidated financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources. However, as of August 31, 2017, 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 $9,049,000 at August 31, 2017. Based on current facts and circumstances, we have estimated the likelihood of payment pursuant to this guarantee is not probable and, therefore, no amount has been recognized in our consolidated financial statements.

We also had in place $15,662,000 of outstanding stand-by letters of credit issued to third-party service providers at August 31, 2017. The fair value of these guarantee instruments, based on premiums paid, was not material and no amounts were drawn against them at August 31, 2017.

NOTE F – Debt and Receivables Securitization

On July 28, 2017, we issued $200,000,000 aggregate principal amount of senior unsecured notes due August 1, 2032 (the “2032 Notes”). The 2032 Notes bear interest at a rate of 4.30%. The 2032 Notes were sold to the public at 99.901% of the principal amount thereof, to yield 4.309% to maturity. We used a portion of the net proceeds from the offering to repay amounts then outstanding under our multi-year revolving credit facility and amounts then outstanding under our revolving trade accounts receivable securitization facility, both of which are described in more detail below. We entered into an interest rate swap in June 2017, in anticipation of the issuance of the 2032 Notes. The interest rate swap had a notional amount of $150,000,000 to hedge the risk of changes in the semi-annual interest rate payments attributable to changes in the benchmark interest rate during the several days leading up to the issuance of the 2032 Notes. Upon pricing of the 2032 Notes, the derivative instrument was settled resulting in a gain of approximately $3,098,000, which was reflected in accumulated other comprehensive income (“AOCI”). Approximately $2,114,000 and $198,000 were allocated to debt issuance costs and the debt discount. The debt issuance costs and the debt discount were recorded on the consolidated balance sheet within long-term debt as a contra-liability. The unamortized portion of the debt issuance costs and debt discount was $2,103,000 and $197,000, respectively, at August 31, 2017.

We maintain a $500,000,000 multi-year revolving credit facility (the “Credit Facility”) with a group of lenders that matures in April 2020. Borrowings under the Credit Facility typically have maturities of less than one year. 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 rate or Fed Funds rate. The applicable margin is determined by our credit rating. There were no borrowings outstanding under the Credit Facility at August 31, 2017. As discussed in “NOTE E – Guarantees,” we provided $15,662,000 in letters of credit for third-party beneficiaries as of August 31, 2017. While not drawn against at August 31, 2017, $14,050,000 of these letters of credit were issued against availability under the Credit Facility, leaving $485,950,000 available under the Credit Facility at August 31, 2017.

9

We also maintain a $100,000,000 revolving trade accounts receivable securitization facility (the “AR Facility”) that matures in January 2018. 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. As of August 31, 2017, no undivided ownership interests in this pool of accounts receivable had been sold.

NOTE G – Other Comprehensive Income

NOTE I – Stock-Based Compensation

Non-Qualified Stock Options

During the three months ended August 31, 2017, we granted non-qualified stock options covering a total of 90,200 common shares under our stock-based compensation plans. The option price of $47.76 per share was equal to the market price of the underlying common shares at the grant date. The fair value of these stock options, based on the Black-Scholes option-pricing model, calculated at the grant date, was $14.99 per share. The calculated pre-tax stock-based compensation expense for these stock options, after an estimate for forfeitures, is $1,203,000 and 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	1.81	%
Expected volatility	36.65	%
Risk-free interest rate	1.98	%
Expected term (years)	6.0

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.

Service-Based Restricted Common Shares

During the three months ended August 31, 2017, we granted an aggregate of 122,400 service-based restricted common shares under our stock-based compensation plans. The fair value of these restricted common shares was equal to the weighted average closing market price of the underlying common shares on the respective dates of grant, or $47.81 per share. The calculated pre-tax stock-based compensation expense for these restricted common shares, after an estimate for forfeitures, is $5,208,000 and will be recognized on a straight-line basis over the three-year service-based vesting period.

11

Performance Share Awards

We have awarded performance shares to certain key employees under our stock-based compensation plans. These performance shares are earned based on the level of achievement with respect to corporate targets for cumulative corporate economic value added, earnings per share growth and, in the case of business unit executives, business unit operating income targets for the three-year periods ending May 31, 2018, 2019 and 2020. These performance share awards will be paid, to the extent earned, in common shares of the Company in the fiscal quarter following the end of the applicable three-year performance period. The fair values of our performance shares are determined by the closing market prices of the underlying common shares at the respective grant dates of the performance shares and the pre-tax stock-based compensation expense is based on our periodic assessment of the probability of the targets being achieved and our estimate of the number of common shares that will ultimately be issued. During the three months ended August 31, 2017, we granted performance share awards covering an aggregate of 54,700 common shares (at target levels). The calculated pre-tax stock-based compensation expense for these performance shares is $2,768,000 and will be recognized over the three-year performance period.

NOTE J – Income Taxes

Income tax expense for the three months ended August 31, 2017 and 2016 reflected estimated annual effective income tax rates of 30.5% and 31.2%, respectively. The annual effective income tax rates exclude any impact from the inclusion of net earnings attributable to noncontrolling interests in our consolidated statements of earnings. Net earnings attributable to noncontrolling interests are primarily a result of our WSP, Spartan, Worthington Aritas, and TWB consolidated joint ventures. The earnings attributable to the noncontrolling interests in WSP, Spartan and TWB’s U.S. operations do not generate tax expense to Worthington since the investors in WSP, Spartan and TWB’s U.S. operations are taxed directly based on the earnings attributable to them. The tax expense of Worthington Aritas (a foreign corporation) and TWB’s wholly-owned foreign corporations is reported in our consolidated tax expense. 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 2018 could be materially different from the forecasted rate as of August 31, 2017.

NOTE K – Earnings per Share

The following table sets forth the computation of basic and diluted earnings per share attributable to controlling interest for the three months ended August 31, 2017 and 2016:

	Three Months Ended August 31,
(in thousands, except per share amounts)	2017		2016
Numerator (basic & diluted):
Net earnings attributable to controlling interest -income available to common shareholders	$	45,534	$	65,567
Denominator:
Denominator for basic earnings per share attributable to controlling interest—weighted average common shares		62,444		61,885
Effect of dilutive securities		2,146		2,452
Denominator for diluted earnings per share attributable to controlling interest—adjusted weighted average common shares		64,590		64,337
Basic earnings per share attributable to controlling interest	$	0.73	$	1.06
Diluted earnings per share attributable to controlling interest	$	0.70	$	1.02

Stock options covering 161,429 common shares have been excluded from the computation of diluted earnings per share for the three months ended August 31, 2016 because the effect of their inclusion would have been “anti-dilutive” for that period.

Effective June 1, 2017, we made certain organizational changes impacting the internal reporting and management structure of Packaging Solutions. As a result of these organizational changes, management responsibilities and internal reporting were realigned, moving Packaging Solutions from the Steel Processing operating segment to the Engineered Cabs operating segment. Previously reported results have not been restated and are immaterial for all periods presented.

NOTE M – Acquisitions

On June 2, 2017, the Company acquired Amtrol, a leading manufacturer of pressure cylinders and water system tanks with operations in the U.S. and Europe. The total purchase price was $291,921,000 after adjusting for excess working capital and was funded primarily with cash on hand. The net assets became part of the Pressure Cylinders operating segment at closing, with the well water and expansion tank operations aligning under the consumer products business and the refrigerant, liquid propane and industrial and specialty gas operations aligning under the industrial products business. Total acquisition-related expenses were $3,568,000 of which $1,568,000 was incurred during the three months ended August 31, 2017.

The information included herein has been prepared based on the preliminary allocation of the purchase price using estimates of the fair value and useful lives of the assets acquired and liabilities assumed. The purchase price allocation is subject to further adjustment until all pertinent information regarding the assets acquired and liabilities assumed are fully evaluated by the Company, including but not limited to, the fair value accounting, legal and tax matters, obligations, and deferred taxes.

The assets acquired and liabilities assumed were recognized at their preliminary acquisition-date fair values, with goodwill representing the excess of the purchase price over the fair value of the net identifiable assets acquired. In connection with the acquisition, we identified and valued the following identifiable intangible assets:

(in thousands)	Amount		Useful Life (Years)
Category
Customer relationships	$	90,800		14-17
Trade names		62,200		Indefinite
Technology		13,000		15-16
Total acquired identifiable intangible assets	$	166,000

The purchase price includes the fair values of other assets that were not identifiable, not separately recognizable under accounting rules (e.g., assembled workforce) or of immaterial value. The purchase price also includes a going-concern element that represents our ability to earn a higher rate of return on this group of assets than would be expected on the separate assets as determined during the valuation process. This additional investment value resulted in goodwill, which is not expected to be deductible for income tax purposes.

The following table summarizes the consideration transferred for the assets of Amtrol and the preliminary fair value assigned to the assets acquired and liabilities assumed at the acquisition date:

(in thousands)
Cash	$	6,893
Accounts receivable		40,212
Inventories		37,249
Prepaid expenses		981
Other assets		2,550
Intangible assets		166,000
Property, plant and equipment		52,870
Total assets		306,755
Accounts payable		25,945
Accrued liabilities		21,016
Long-term debt including current maturities		2,287
Other accrued items		3,993
Deferred income taxes, net		64,495
Net identifiable assets		189,019
Goodwill		102,902
Purchase price	$	291,921
Less: excess working capital		(523	)
Cash paid at closing	$	291,398

14

The Company’s results of operations for the three months ended August 31, 2017 included the operating results of Amtrol since the date of acquisition. Net sales and operating loss of Amtrol were $57,346,000 and $2,611,000, respectively, for the three months ended August 31, 2017. The following unaudited pro forma information presents consolidated financial information as if Amtrol had been acquired at the beginning of fiscal 2017. Depreciation and amortization expense included in the pro forma results reflect the preliminary acquisition-date fair values assigned to the definite-lived intangible assets and fixed assets of Amtrol assuming a June 1, 2016 acquisition date. Adjustment has also been made for acquisition-related costs incurred in each period presented. Pro forma results for the three months ended August 31, 2017, have also been adjusted to remove the impact of the acquisition-date fair value adjustments to inventories and accrued severance costs related to headcount reductions at Amtrol initiated during the current period, as discussed in “NOTE C – Restructuring and Other Expense.” The pro forma adjustments noted above have been adjusted for the applicable income tax impact. The pro forma information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition had taken place at such time.

	Three months ended August 31,
(in thousands, except per share amounts)	2017		2016
Net sales	$	848,237	$	795,544
Net earnings attributable to controlling interest	$	49,471	$	70,357
Diluted earnings per share attributable to controlling interest	$	0.77	$	1.09

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, foreign currency exchange rate 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.

Foreign Currency Exchange Risk Management – We conduct business in several major international currencies and are therefore subject to risks associated with changing foreign currency exchange rates. We enter into various contracts that change in value as foreign currency exchange rates change to manage this exposure. Such contracts limit exposure to both favorable and unfavorable currency exchange rate fluctuations. The translation of foreign currencies into United States dollars also subjects us to exposure related to fluctuating currency 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 contracts 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. We have credit support agreements in place with certain counterparties to limit our credit exposure. These agreements require either party to post cash collateral if its cumulative market position exceeds a predefined liability threshold. Amounts posted to the margin accounts accrue interest at market rates and are required to be refunded in the period in which the cumulative market position falls below the required threshold. 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 OCI and reclassified into earnings in the same line 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 August 31, 2017:

(in thousands)	Notional Amount		Maturity Date
Commodity contracts	$	25,372	September 2017 - June 2019

The estimated net amount of the losses recognized in AOCI at August 31, 2017 expected to be reclassified into net earnings within the succeeding twelve months is $5,666,000 (net of tax of $3,425,000). This amount was computed using the fair value of the cash flow hedges at August 31, 2017, and will change before actual reclassification from other comprehensive income to net earnings during the fiscal years ending May 31, 2018 and May 31, 2019.

Economic (Non-designated) Hedges

We enter into foreign currency exchange contracts to manage our foreign currency exchange rate 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.

The following table summarizes our economic (non-designated) derivative instruments outstanding at August 31, 2017:

(in thousands)	Notional Amount		Maturity Date(s)
Commodity contracts	$	20,346	September 2017 - February 2019
Foreign exchange contracts		4,921	September 2017

The gain (loss) on the foreign currency exchange contracts derivatives significantly offsets the gain (loss) on the hedged item.

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	–	Inputs other than quoted prices included within Level 1 that are observable for the assets and liabilities, either directly or indirectly.
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 August 31, 2017, our assets and liabilities measured at fair value on a recurring basis were as follows:

(in thousands)	Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Totals

(1) The fair value of our derivative instruments 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.

(2) The fair value of the contingent consideration obligation is determined using a probability weighted cash flow approach based on management’s projections of future cash flows of the acquired business. The fair value measurement was based on Level 3 inputs not observable in the market.

The fair value of non-derivative financial instruments included in the carrying amounts of cash and cash equivalents, receivables, notes receivable, income taxes receivable, other assets, 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 $835,414,000 and $618,059,000 at August 31, 2017 and May 31, 2017, respectively. The carrying amount of long-term debt, including current maturities, was $780,162,000 and $578,487,000 at August 31, 2017 and May 31, 2017, respectively.

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

Selected statements contained in this “Item 2. – Management’s Discussion and Analysis of Financial Condition and Results of Operations” constitute “forward-looking statements” as that term is used in the Private Securities Litigation Reform Act of 1995. Such forward-looking statements are based, in whole or in part, on management’s beliefs, estimates, assumptions and currently available information. For a more detailed discussion of what constitutes a forward-looking statement and of some of the factors that could cause actual results to differ materially from such forward-looking statements, please refer to the “Safe Harbor Statement” in the beginning of this Quarterly Report on Form 10-Q and “Part I—Item 1A.—Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended May 31, 2017.

Introduction

The following discussion and analysis of market and industry trends, business developments, and the results of operations and financial position of Worthington Industries, Inc., together with its subsidiaries (collectively, “we,” “our,” “Worthington,” or our “Company”), should be read in conjunction with our consolidated financial statements and notes thereto included in “Item 1. –Financial Statements” of this Quarterly Report on Form 10-Q. Our Annual Report on Form 10-K for the fiscal year ended May 31, 2017 (“fiscal 2017”) includes additional information about Worthington, our operations and our consolidated financial position and should be read in conjunction with this Quarterly Report on Form 10-Q.

As of August 31, 2017, excluding our joint ventures, we operated 34 manufacturing facilities worldwide, principally in three operating segments, which correspond with our reportable business segments: Steel Processing, Pressure Cylinders and Engineered Cabs. The Worthington Energy Innovations (“WEI”) operating segment does not meet the applicable aggregation criteria or quantitative thresholds for separate disclosure, and therefore is combined and reported in the “Other” category.

As of August 31, 2017, we held equity positions in 11 joint ventures, which operated 51 manufacturing facilities worldwide. Five of these joint ventures are consolidated with the equity owned by the other joint venture member(s) shown as noncontrolling interests in our consolidated balance sheets, and their portions of net earnings and other comprehensive income (loss) shown as net earnings or comprehensive income attributable to noncontrolling interests in our consolidated statements of earnings and consolidated statements of comprehensive income, respectively. The remaining six of these joint ventures are accounted for using the equity method.

Overview

The Company delivered overall sales growth of 15% for the first quarter of fiscal 2018 over the comparable period of fiscal 2017, on contributions from the acquisition of Amtrol on June 2, 2017, as discussed below under Recent Business Developments, and higher average selling prices in Steel Processing. Net earnings declined from the record levels achieved in the prior year quarter, when rising steel prices led to record direct spreads at Steel Processing. By comparison, steel prices were relatively stable during the first quarter of fiscal 2018 resulting in small inventory holding losses. Pressure Cylinders’ results were down from the prior year quarter as contributions from Amtrol and improvements in the oil & gas equipment business were more than offset by incremental expense directly associated with the Amtrol acquisition and declines in the alternative fuels business.

Equity in net income of unconsolidated affiliates (“equity income”) decreased $7.2 million from the prior year quarter due primarily to lower contributions from ClarkDietrich, partially offset by minor increases at WAVE and Serviacero. ClarkDietrich’s contribution to equity income was $7.9 million lower than the prior year quarter as higher steel prices compressed margins. We received distributions from unconsolidated joint ventures of $19.6 million during the first quarter of fiscal 2018.

Recent Business Developments

• On June 2, 2017, the Company acquired Amtrol, a leading manufacturer of pressure cylinders and water system tanks with operations in the U.S. and Europe. The total purchase price was $291.9 million after adjusting for excess working capital and was funded primarily with cash on hand. The net assets became part of the Pressure Cylinders operating segment at closing, with the well water and expansion tank operations aligning under the consumer products business and the refrigerant, liquid propane and industrial and specialty gas operations aligning under the industrial products business. Refer to “Item 1. – Financial Statements – Notes to Consolidated Financial Statements – NOTE M – Acquisitions.”

21

• On July 28, 2017, the Company completed the public offering of $200.0 million aggregate principal amount of senior unsecured notes. The notes bear interest at a rate of 4.30% and mature on August 1, 2032. Refer to “Item 1. – Financial Statements – Notes to Consolidated Financial Statements – NOTE F – Debt and Receivables Securitization.”

• Effective June 1, 2017, the Company changed the internal reporting and management structure of its Packaging Solutions business. As a result, management responsibilities and internal reporting were realigned, moving from Steel Processing to Engineered Cabs. Previously reported results have not been restated and are immaterial for all periods presented.

• During the first quarter of fiscal 2018, the Company repurchased a total of 875,000 common shares for $45.1 million at an average price of $51.52 per share.

• On September 27, 2017, the Board of Directors of Worthington Industries, Inc. (the “Board”) declared a quarterly dividend of $0.21 per share payable on December 29, 2017, to shareholders of record on December 15, 2017.

• On September 27, 2017, the Board authorized the repurchase of up to an additional 6,828,855 of the Company’s common shares, increasing the total number of common shares available for repurchase to 10,000,000.

Market & Industry Overview

We sell our products and services to a diverse customer base and a broad range of end markets. The breakdown of our net sales by end market for the first quarter of each of fiscal 2018 and fiscal 2017 is illustrated in the following chart:

The automotive industry is one of the largest consumers of flat-rolled steel, and thus the largest end market for our Steel Processing operating segment. Approximately 58% of Steel Processing’s net sales are to the automotive market. North American vehicle production, primarily by Ford, General Motors and FCA US (the “Detroit Three automakers”), has a considerable impact on the activity within this operating segment. The majority of the net sales of three of our unconsolidated joint ventures are also to the automotive end market.

Approximately 14% of the net sales of our Steel Processing operating segment and 48% of the net sales of our Engineered Cabs operating segment are to the construction market. The construction market is also the predominant end market for two of our unconsolidated joint ventures: WAVE and ClarkDietrich. While the market price of steel significantly impacts these businesses, there are other key indicators that are meaningful in analyzing construction market demand, including U.S. gross domestic product (“GDP”), the Dodge Index of construction contracts and, in the case of ClarkDietrich, trends in the relative price of framing lumber and steel.

22

Substantially all of the net sales of our Pressure Cylinders operating segment, and approximately 28% and 52% of the net sales of our Steel Processing and Engineered Cabs operating segments, respectively, are to other markets such as consumer products, industrial, lawn and garden, agriculture, oil & gas equipment, heavy truck, mining, forestry and appliance. Given the many different products that make up these net sales and the wide variety of end markets, it is very difficult to detail the key market indicators that drive these portions of our business. However, we believe that the trend in U.S. GDP growth is a good economic indicator for analyzing these businesses.

We use the following information to monitor our costs and demand in our major end markets:

U.S. GDP growth rate trends are generally indicative of the strength in demand and, in many cases, pricing for our products. A year-over-year increase in U.S. GDP growth rates is indicative of a stronger economy, which generally increases demand and pricing for our products. Conversely, decreasing U.S. GDP growth rates generally indicate a weaker economy. Changes in U.S. GDP growth rates can also signal changes in conversion costs related to production and in selling, general and administrative (“SG&A”) expense.

The market price of hot-rolled steel is one of the most significant factors impacting our selling prices and operating results. When steel prices fall, we typically have higher-priced material flowing through cost of goods sold, while selling prices compress to what the market will bear, negatively impacting our results. On the other hand, in a rising price environment, our results are generally favorably impacted, as lower-priced material purchased in previous periods flows through cost of goods sold, while our selling prices increase at a faster pace to cover current replacement costs.

The following table presents the average quarterly market price per ton of hot-rolled steel during fiscal 2018 (first quarter), fiscal 2017 and fiscal 2016:

(Dollars per ton 1 )
	Fiscal Year

4th Quarter		N/A	$	636	$	486
Annual Avg.	$	604	$	601	$	437

¹ CRU Hot-Rolled Index, period average

No single customer contributed more than 10% of our consolidated net sales during the first quarters of fiscal 2018 or fiscal 2017. While our automotive business is largely driven by the production schedules of the Detroit Three automakers, our customer base is much broader and includes other domestic manufacturers and many of their suppliers. During the first quarter of fiscal 2018, vehicle production for the Detroit Three automakers was down 9%, while North American vehicle production as a whole was down 10%.

23

Certain other commodities, such as zinc, natural gas and diesel fuel, represent a significant portion of our cost of goods sold, both directly through our manufacturing operations and indirectly through transportation and freight expense.

Total	$	27.3					$	34.5					$	(7.2	)

Net earnings attributable to controlling interest for the three months ended August 31, 2017 decreased $20.1 million from the comparable period in the prior year. Net sales and operating highlights were as follows:

• Net sales increased $110.7 million over the comparable period in the prior year. The increase was driven by contributions from the acquisition of Amtrol, which totaled $57.3 million, and higher average selling prices in Steel Processing, up $43.2 million over the prior year. The balance of the increase was primarily the result of increased volume at Pressure Cylinders and Engineered Cabs.

• Gross margin decreased $14.6 million from the comparable period in the prior year. Contributions from the acquisition of Amtrol were more than offset by lower spreads in Steel Processing, down approximately $23.4 million from the prior year quarter when rising steel prices led to significant inventory holding gains.

• SG&A expense increased $7.1 million over the comparable period in the prior year. The increase was driven by the impact of the Amtrol acquisition, partially offset by lower profit sharing and bonus expense. Overall, SG&A expense was 10.4% of consolidated net sales compared to 11.0% in the comparable period of the prior year.

24

• Restructuring and other expense totaled $2.3 million in the current period and consisted primarily of severance accruals at Pressure Cylinders related to corporate management positions at Amtrol that were eliminated. For additional information regarding the Company’s restructuring activities, refer to “Item 1. – Financial Statements – Notes to Consolidated Financial Statements – NOTE C – Restructuring and Other Expense.”

• Interest expense increased $0.9 million over the comparable period in the prior year. The increase was primarily due to the issuance of $200.0 million of aggregate principal amount senior unsecured notes due August 1, 2032. Refer to “Item 1. – Financial Statements – Notes to Consolidated Financial Statements – NOTE F – Debt and Receivables Securitization.”

• Equity income decreased $7.2 million from the comparable period in the prior year due primarily to lower contributions from ClarkDietrich, partially offset by minor increases at WAVE and Serviacero. ClarkDietrich’s contribution to equity income was $7.9 million lower than the prior year quarter as higher steel prices compressed margins. We received distributions of $19.6 million from our unconsolidated affiliates during the quarter. For additional information regarding our unconsolidated affiliates, refer to “Item 1. – Financial Statements – Notes to Consolidated Financial Statements – NOTE B – Investments in Unconsolidated Affiliates.”

• Income tax expense decreased $10.9 million from the comparable period in the prior year due primarily to lower earnings. The current quarter expense was calculated using an estimated annual effective income tax rate of 30.5% versus 31.2% in the prior year quarter. Discrete items in the current quarter reduced income tax expense by $6.2 million, including a net benefit of $3.8 million related to the acquisition of Amtrol. Discrete items in the prior year quarter reduced income tax expense by $5.8 million. Refer to “Item 1. – Financial Statements – Notes to Consolidated Financial Statements – NOTE J – Income Taxes” for more information on our tax rates.

Material cost	$	379.2				$	312.7				$	66.5
Tons shipped (in thousands)		968					1,032					(64	)

Net sales and operating highlights were as follows:

• Net sales increased $37.8 million over the comparable period in the prior year driven by higher average direct selling prices, which increased net sales by $43.2 million, partially offset by lower toll volume. The mix of direct versus toll tons processed was 56% to 44% compared to 52% to 48% in the prior year quarter.

• Operating income decreased $21.9 million from the comparable period in the prior year due to a lower spread between average selling prices and material costs, down approximately $23.4 million from the prior year quarter when rising steel prices led to significant inventory holding gains.

Oil & gas equipment		703					756					(53	)
Total Pressure Cylinders		20,441,276					18,915,878					1,525,398

Net sales and operating highlights were as follows:

• Net sales increased $64.6 million over the comparable period in the prior year due to contributions from the Amtrol acquisition, which totaled $57.3 million, and higher volumes in the oil & gas equipment business, partially offset by lower volumes in the alternative fuels business.

• Operating income decreased $3.6 million from the comparable period in the prior year. The decrease was driven by incremental items directly associated with the Amtrol acquisition, which resulted in a net operating loss of $2.6 million for the acquired business. This included $2.6 million of additional expense within cost of goods sold for the write-up of inventory to fair value that was subsequently sold, $1.6 million of acquisition-related costs within SG&A expense and a $1.9 million severance accrual within restructuring expense. Improvements in the oil & gas equipment business and lower SG&A spend for the legacy cylinder businesses was largely offset by declines in the alternative fuels business.

Net sales and operating highlights were as follows:

• Net sales increased $1.9 million over the comparable period in the prior year on higher volumes at WEI.

• Operating loss of $0.7 million represents a $1.4 million improvement over the prior year period. The improvement was driven by higher earnings at WEI.

Liquidity and Capital Resources

During the three months ended August 31, 2017, we generated $83.4 million of cash from operating activities, invested $18.0 million in property, plant and equipment, spent $284.5 million on acquisitions and paid dividends of $12.8 million on our common shares. Additionally, we paid $45.1 million to repurchase 875,000 of our common shares. The following table summarizes our consolidated cash flows for the three months ended August 31, 2017 and 2016:

	Three Months Ended August 31,
(in millions)	2017			2016
Net cash provided by operating activities	$	83.4		$	120.9
Net cash used by investing activities		(302.1	)		(16.2	)
Net cash provided (used) by financing activities		136.5			(7.4	)

Cash and cash equivalents at beginning of period		278.1			84.2
Cash and cash equivalents at end of period	$	195.9		$	181.5

We believe we have access to adequate resources to meet the needs of our existing businesses for normal operating costs, mandatory capital expenditures, debt redemptions, dividend payments, and working capital. These resources include cash and cash equivalents, cash provided by operating activities and unused lines of credit. We also believe that we have adequate access to the financial markets to allow us to be in a position to sell long-term debt or equity securities. However, uncertainty and volatility in the financial markets may impact our ability to access capital and the terms under which we can do so.

Operating Activities

Our business is cyclical and cash flows from operating activities may fluctuate during the year and from year to year due to economic conditions. We rely on cash and short-term borrowings to meet cyclical increases in working capital needs. These needs generally rise during periods of increased economic activity or increasing raw material prices due to higher levels of inventory and accounts receivable. During economic slowdowns, or periods of decreasing raw material costs, working capital needs generally decrease as a result of the reduction of inventories and accounts receivable.

Net cash provided by operating activities was $83.4 million during the three months ended August 31, 2017 compared to $120.9 million in the comparable period of fiscal 2017. The decrease was driven primarily by the decline in net earnings and lower distributions from unconsolidated joint ventures.

Investing Activities

Net cash used by investing activities was $302.1 million during the three months ended August 31, 2017 compared to $16.2 million in the prior year period. The increase from the prior year period was driven primarily by the acquisition of Amtrol on June 2, 2017, which reduced cash by $284.5 million, net of cash acquired. We also made capital expenditures of $18.0 million during the first three months of fiscal 2018.

Investment activities are largely discretionary, and future investment activities could be reduced significantly, or eliminated, as economic conditions warrant. We assess acquisition opportunities as they arise, and such opportunities may require additional financing. There can be no assurance, however, that any such opportunities will arise, that any such acquisitions will be consummated, or that any needed additional financing will be available on satisfactory terms when required.

28

Financing Activities

Net cash provided by financing activities was $136.5 million during the three months ended August 31, 2017 compared to a net cash outflow of $7.4 million in the comparable prior year period. The increase from the prior year period was driven primarily by the issuance of $200.0 million aggregate principal amount of senior unsecured notes on July 28, 2017, partially offset by share repurchases. During the first three months of fiscal 2018, we paid $45.1 million to repurchase 875,000 of our common shares.

As of August 31, 2017, we were in compliance with our short-term and long-term financial debt covenants. These debt agreements do not include credit rating triggers or material adverse change provisions. Our credit ratings at August 31, 2017 were unchanged from those reported as of May 31, 2017.

Common shares - The Board of Directors of Worthington Industries, Inc. declared a quarterly dividend of $0.21 per common share for the first quarter of fiscal 2018 compared to $0.20 per common share for the first quarter of fiscal 2017. Dividends paid on our common shares totaled $12.8 million and $11.9 million during the three months ended August 31, 2017 and 2016, respectively. On September 27, 2017, the Board declared a quarterly dividend of $0.21 per share payable on December 29, 2017, to shareholders of record on December 15, 2017.

On June 25, 2014, the Board authorized the repurchase of up to 10,000,000 of our outstanding common shares. A total of 6,828,855 common shares have been repurchased under this authorization, including 875,000 during the first three months of fiscal 2018, leaving 3,171,145 common shares available for repurchase. On September 27, 2017, the Board authorized the repurchase of up to an additional 6,828,855 of the Company’s common shares, increasing the total number of common shares available for repurchase to 10,000,000.

The common shares available for repurchase under the authorizations, described above, may be purchased from time to time, with consideration given to the market price of the common shares, the nature of other investment opportunities, cash flows from operations, general economic conditions and other relevant considerations. Repurchases may be made on the open market or through privately negotiated transactions.

Dividend Policy

We currently have no material contractual or regulatory restrictions on the payment of dividends. Dividends are declared at the discretion of the Board. The Board reviews the dividend quarterly and establishes the dividend rate based upon our consolidated financial condition, results of operations, capital requirements, current and projected cash flows, business prospects, and other relevant factors. While we have paid a dividend every quarter since becoming a public company in 1968, there is no guarantee that payments will continue in the future.

Contractual Cash Obligations and Other Commercial Commitments

Our contractual cash obligations and other commercial commitments have not changed significantly from those disclosed in “Part II – Item 7. – Management’s Discussion and Analysis of Financial Condition and Results of Operations – Contractual Cash Obligations and Other Commercial Commitments” of our 2017 Form 10-K, other than the changes in borrowings, as described in “Part I – Item 1. – Financial Statements – NOTE F – Debt and Receivables Securitization” of this Quarterly Report on Form 10-Q.

Off-Balance Sheet Arrangements

We do not have guarantees or other off-balance sheet financing arrangements that we believe are reasonably likely to have a material current or future effect on our consolidated financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources. However, as of August 31, 2017, 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 $9.0 million at August 31, 2017. Based on current facts and circumstances, we have estimated the likelihood of payment pursuant to this guarantee is not probable and, therefore, no amounts have been recognized in our consolidated financial statements.

Recently Adopted Accounting Standards

In July 2015, amended accounting guidance was issued regarding the measurement of inventory. The amended guidance requires that inventory accounted for under the first-in, first-out (FIFO) or average cost methods be measured at the lower of cost and net realizable value, where net realizable value represents the estimated selling price of inventory in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The amended guidance has no impact on inventory accounted for under the last-in, first-out (LIFO) or retail inventory methods. The Company adopted this amended guidance on a prospective basis effective June 1, 2017. The adoption of this guidance did not impact our consolidated financial position or results of operations.

Recently Issued Accounting Standards

In May 2014, new accounting guidance was issued that replaces most existing revenue recognition guidance under U.S. GAAP. The new guidance requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. Subsequently, additional guidance was issued on several areas including guidance intended to improve the operability and understandability of the implementation of principal versus agent considerations and clarifications on the identification of performance obligations and implementation of guidance related to licensing. The new guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The guidance permits the use of either the retrospective or cumulative effect transition method. We are in the process of evaluating the effect this guidance will have on the presentation of our consolidated financial statements and related disclosures. While we have not yet identified any material changes in the timing of revenue recognition, our evaluation is ongoing and not complete. We plan to adopt the new guidance in the first quarter of fiscal 2019. The Company will continue to monitor any modifications, clarifications, and interpretations by the FASB that may impact its conclusions.

In February 2016, new accounting guidance was issued that replaces most existing lease accounting guidance under U.S. GAAP. Among other changes, the new guidance requires that lease assets and liabilities be recognized on the balance sheet by lessees for those leases classified as operating leases under previous guidance. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted, and the change is to be applied using a modified retrospective approach as of the beginning of the earliest period presented. We are in the process of evaluating the effect this guidance will have on our consolidated financial position, results of operations and cash flows, and we have not determined the effect of the new guidance on our ongoing financial reporting.

In June 2016, new accounting guidance was issued related to the measurement of credit losses on financial instruments. The new guidance changes the impairment model for most financial assets to require measurement and recognition of expected credit losses for financial assets held. The new guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and we have not determined the effect of the new guidance on our ongoing financial reporting.

In August 2016, amended accounting guidance was issued to clarify the proper cash flow presentation of certain specific types of cash payments and cash receipts. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position, results of operations and cash flows, and we have not determined the effect of the amended guidance on our ongoing financial reporting.

In October 2016, amended accounting guidance was issued that requires the income tax consequences of an intra-entity transfer of an asset other than inventory to be recognized when the transfer occurs. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position, results of operations and cash flows, and have not determined the effect of the amended guidance on our ongoing financial reporting.

30

In November 2016, amended accounting guidance was issued that requires amounts generally described as restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a material impact on our consolidated cash flows.

In January 2017, amended accounting guidance was issued to clarify the definition of a business to provide additional guidance to assist in evaluating whether transactions should be accounted for as an acquisition (or disposal) of either an asset or business. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a material impact on our consolidated financial position or results of operations.

In January 2017, amended accounting guidance was issued to simplify the goodwill impairment calculation, by removing Step 2 of the goodwill impairment test. Goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of the goodwill. The amended guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and have not determined the effect on our ongoing financial reporting.

In March 2017, amended accounting guidance was issued that requires an employer to report the service cost component of pension and postretirement benefits in the same line as other current employee compensation costs. Additionally, other components of net benefit cost are to be presented in the income statement separately from the service cost component and outside of income from operations. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and have not determined the effect on our ongoing financial reporting.

In May 2017, amended accounting guidance was issued to provide guidance about which changes to the terms or conditions of a share-based payment award require application of modification accounting. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a material impact on our consolidated financial position or results of operations.

In August 2017, amended accounting guidance was issued that modifies hedge accounting by making more hedge strategies eligible for hedge accounting, amending presentation and disclosure requirements, and changing how companies assess effectiveness. The intent is to simplify application of hedge accounting and increase transparency of information about an entity’s risk management activities. The amended guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and have not determined the effect on our ongoing financial reporting.

Critical Accounting Policies

The discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. We continually evaluate our estimates, including those related to our valuation of receivables, intangible assets, accrued liabilities, income and other tax accruals, and contingencies and litigation. We base our estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances. These results form the basis for making judgments about the carrying values of assets and liabilities that are not readily obtained from other sources. Critical accounting policies are defined as those that require our significant judgments and involve uncertainties that could potentially result in materially different results under different assumptions and conditions. Although actual results historically have not deviated significantly from those determined using our estimates, our financial position or results of operations could be materially different if we were to report under different conditions or to use different assumptions in the application of such policies. Our critical accounting policies have not significantly changed from those discussed in “Part II – Item 7. – Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies” of our 2017 Form 10-K.

Item 3. –  Quantitative and Qualitative Disclosures About Market Risk

Market risks have not changed significantly from those disclosed in “Part II—Item 7A. – Quantitative and Qualitative Disclosures About Market Risk” of our 2017 Form 10-K.

Item 4. – Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures [as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)] that are designed to provide reasonable assurance that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and our principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Management, with the participation of our principal executive officer and our principal financial officer, performed an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q (the fiscal quarter ended August 31, 2017). Based on that evaluation, our principal executive officer and our principal financial officer have concluded that such disclosure controls and procedures were effective at a reasonable assurance level as of the end of the period covered by this Quarterly Report on Form 10-Q.

Changes in Internal Control Over Financial Reporting

There were no changes that occurred during the period covered by this Quarterly Report on Form 10-Q (the fiscal quarter ended August 31, 2017) in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

32

PART II. OTHER INFORMATION

Item 1. – Legal Proceedings

Various legal actions, which generally have arisen in the ordinary course of business, are pending against the Company. None of this pending litigation, individually or collectively, is expected to have a material adverse effect on our consolidated financial position, results of operations or cash flows.

Item 1A. – Risk Factors

There are certain risks and uncertainties in our business that could cause our actual results to differ materially from those anticipated. In “PART I – Item 1A. – Risk Factors” of the Annual Report on Form 10-K of Worthington Industries, Inc. for the fiscal year ended May 31, 2017 (the “2017 Form 10-K”), as filed with the Securities and Exchange Commission on July 24, 2017, and available at www.sec.gov or at www.worthingtonindustries.com, we included a detailed discussion of our risk factors. Our risk factors have not changed significantly from those disclosed in our 2017 Form 10-K. These risk factors should be read carefully in connection with evaluating our business and in connection with the forward-looking statements and other information contained in this Quarterly Report on Form 10-Q. Any of the risks described in our 2017 Form 10-K could materially affect our business, consolidated financial condition or future results and the actual outcome of matters as to which forward-looking statements are made. The risk factors described in our 2017 Form 10-K are not the only risks we face. Additional risks and uncertainties not currently known to us, or that we currently deem to be immaterial, also may materially adversely affect our business, consolidated financial condition and/or future results.

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

The following table provides information about purchases made by, or on behalf of, Worthington Industries, Inc. or any “affiliated purchaser” (as defined in Rule 10b-18(a) (3) under the Securities Exchange Act of 1934, as amended) of common shares of Worthington Industries, Inc. during each month of the fiscal quarter ended August 31, 2017:

Basis of Presentation

NOTE A – Basis of Presentation

The 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.

The Company owns controlling interests in the following five joint ventures: Spartan Steel Coating, LLC (“Spartan”) (52%), TWB Company, L.L.C. (“TWB”) (55%), Worthington Aritaş Basinçli Kaplar Sanayi (“Worthington Aritas”) (75%), Worthington Energy Innovations, LLC (“WEI”) (75%), and Worthington Specialty Processing (“WSP”) (51%). These joint ventures are consolidated with the equity owned by the other joint venture members shown as noncontrolling interests in our consolidated balance sheets, and their portions of net earnings and other comprehensive income (loss) (“OCI”) shown as net earnings or comprehensive income attributable to noncontrolling interests in our consolidated statements of earnings and consolidated statements of comprehensive income, respectively.

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 consolidated financial statements for these interim periods, have been included. Operating results for the three months ended August 31, 2017 are not necessarily indicative of the results that may be expected for the fiscal year ending May 31, 2018 (“fiscal 2018”). 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, 2017 (“fiscal 2017”) of Worthington Industries, Inc. (the “2017 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 consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Recently Adopted Accounting Standards

In July 2015, amended accounting guidance was issued regarding the measurement of inventory. The amended guidance requires that inventory accounted for under the first-in, first-out (FIFO) or average cost methods be measured at the lower of cost and net realizable value, where net realizable value represents the estimated selling price of inventory in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The amended guidance has no impact on inventory accounted for under the last-in, first-out (LIFO) or retail inventory methods. The Company adopted this amended guidance on a prospective basis effective June 1, 2017. The adoption of this guidance did not impact our consolidated financial position or results of operations.

Recently Issued Accounting Standards

In May 2014, new accounting guidance was issued that replaces most existing revenue recognition guidance under U.S. GAAP. The new guidance requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. Subsequently, additional guidance was issued on several areas including guidance intended to improve the operability and understandability of the implementation of principal versus agent considerations and clarifications on the identification of performance obligations and implementation of guidance related to licensing. The new guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The guidance permits the use of either the retrospective or cumulative effect transition method. We are in the process of evaluating the effect this guidance will have on the presentation of our consolidated financial statements and related disclosures. While we have not yet identified any material changes in the timing of revenue recognition, our evaluation is ongoing and not complete. We plan to adopt the new guidance in the first quarter of fiscal 2019. The Company will continue to monitor any modifications, clarifications, and interpretations by the FASB that may impact its conclusions.

In February 2016, new accounting guidance was issued that replaces most existing lease accounting guidance under U.S. GAAP. Among other changes, the new guidance requires that lease assets and liabilities be recognized on the balance sheet by lessees for those leases classified as operating leases under previous guidance. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted, and the change is to be applied using a modified retrospective approach as of the beginning of the earliest period presented. We are in the process of evaluating the effect this guidance will have on our consolidated financial position, results of operations and cash flows, and we have not determined the effect of the new guidance on our ongoing financial reporting.

In June 2016, new accounting guidance was issued related to the measurement of credit losses on financial instruments. The new guidance changes the impairment model for most financial assets to require measurement and recognition of expected credit losses for financial assets held. The new guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and we have not determined the effect of the new guidance on our ongoing financial reporting.

In August 2016, amended accounting guidance was issued to clarify the proper cash flow presentation of certain specific types of cash payments and cash receipts. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position, results of operations and cash flows, and we have not determined the effect of the amended guidance on our ongoing financial reporting.

In October 2016, amended accounting guidance was issued that requires the income tax consequences of an intra-entity transfer of an asset other than inventory to be recognized when the transfer occurs. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position, results of operations and cash flows, and have not determined the effect of the amended guidance on our ongoing financial reporting.

In November 2016, amended accounting guidance was issued that requires amounts generally described as restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a material impact on our consolidated cash flows.

In January 2017, amended accounting guidance was issued to clarify the definition of a business to provide additional guidance to assist in evaluating whether transactions should be accounted for as an acquisition (or disposal) of either an asset or business. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a material impact on our consolidated financial position or results of operations.

In January 2017, amended accounting guidance was issued to simplify the goodwill impairment calculation, by removing Step 2 of the goodwill impairment test. Goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of the goodwill. The amended guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and have not determined the effect on our ongoing financial reporting.

In March 2017, amended accounting guidance was issued that requires an employer to report the service cost component of pension and postretirement benefits in the same line as other current employee compensation costs. Additionally, other components of net benefit cost are to be presented in the income statement separately from the service cost component and outside of income from operations. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and have not determined the effect on our ongoing financial reporting.

In May 2017, amended accounting guidance was issued to provide guidance about which changes to the terms or conditions of a share-based payment award require application of modification accounting. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a material impact on our consolidated financial position or results of operations.

In August 2017, amended accounting guidance was issued that modifies hedge accounting by making more hedge strategies eligible for hedge accounting, amending presentation and disclosure requirements, and changing how companies assess effectiveness. The intent is to simplify application of hedge accounting and increase transparency of information about an entity’s risk management activities. The amended guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and have not determined the effect on our ongoing financial reporting.

Investments in Unconsolidated Affiliates

Unconsolidated Affiliates

Investments in Unconsolidated Affiliates

NOTE B – Investments in Unconsolidated Affiliates

Investments in affiliated companies that we do not control, either through majority ownership or otherwise, are accounted for using the equity method. These include ArtiFlex Manufacturing, LLC (“ArtiFlex”) (50%), Clarkwestern Dietrich Building Systems LLC (“ClarkDietrich”) (25%), Samuel Steel Pickling Company (31.25%), Serviacero Planos, S. de R. L. de C.V. (“Serviacero”) (50%), Worthington Armstrong Venture (“WAVE”) (50%), and Zhejiang Nisshin Worthington Precision Specialty Steel Co., Ltd. (10%).

We received distributions from unconsolidated affiliates totaling $19,551,000 during the three months ended August 31, 2017. We have received cumulative distributions from WAVE in excess of our investment balance, which resulted in an amount recorded within other liabilities on our consolidated balance sheets of $58,371,000 at August 31, 2017. In accordance with the applicable accounting guidance, we reclassified the negative balance 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 probable 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 received, less distributions received in prior periods that were determined to be returns of investment, 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.

Restructuring and Other Expense

NOTE C – Restructuring and Other Expense

We consider restructuring activities to be programs whereby we fundamentally change our operations such as closing and consolidating manufacturing facilities or moving manufacturing of a product to another location. Restructuring activities may also involve substantial realignment of the management structure of a business unit in response to changing market conditions.

A progression of the liabilities associated with our restructuring activities, combined with a reconciliation to the restructuring and other expense financial statement caption, in our consolidated statement of earnings for the three months ended August 31, 2017 is summarized below:

(in thousands)	Beginning Balance		Expense		Payments			Adjustments		Ending Balance
Early retirement and severance	$	253	$	1,877	$	(182	)	$	127	$	2,075
Facility exit and other costs		536		284		(950	)		131		1
	$	789		2,161	$	(1,132	)	$	258	$	2,076
Net loss on sale of assets				143
Restructuring and other expense			$	2,304

During the three months ended August 31, 2017, the following actions were taken related to the Company’s restructuring activities:

• In connection with the acquisition of Amtrol on June 2, 2017, the Company recognized severance expense of $1,877,000 related to corporate management positions at Amtrol that were eliminated.

• In connection with the closure of the Company’s stainless steel business, Precision Specialty Metals, Inc. (“PSM”), the Company recognized facility exit costs of $279,000.

• In connection with other non-significant restructuring activities, the Company recognized facility exit costs of $5,000. The Company also recognized a net loss on disposal of assets of $143,000.

The total liability associated with our restructuring activities as of August 31, 2017 is expected to be paid in the next twelve months.

Contingent Liabilities and Commitments

NOTE D – Contingent Liabilities and Commitments

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 have a material adverse effect on our consolidated financial position or future results of operations or cash flows. We believe that environmental issues will not have a material effect on our capital expenditures, consolidated financial position or future results of operations or cash flows.

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 consolidated financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources. However, as of August 31, 2017, 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 $9,049,000 at August 31, 2017. Based on current facts and circumstances, we have estimated the likelihood of payment pursuant to this guarantee is not probable and, therefore, no amount has been recognized in our consolidated financial statements.

We also had in place $15,662,000 of outstanding stand-by letters of credit issued to third-party service providers at August 31, 2017. The fair value of these guarantee instruments, based on premiums paid, was not material and no amounts were drawn against them at August 31, 2017.

Debt and Receivables Securitization

NOTE F – Debt and Receivables Securitization

On July 28, 2017, we issued $200,000,000 aggregate principal amount of senior unsecured notes due August 1, 2032 (the “2032 Notes”). The 2032 Notes bear interest at a rate of 4.30%. The 2032 Notes were sold to the public at 99.901% of the principal amount thereof, to yield 4.309% to maturity. We used a portion of the net proceeds from the offering to repay amounts then outstanding under our multi-year revolving credit facility and amounts then outstanding under our revolving trade accounts receivable securitization facility, both of which are described in more detail below. We entered into an interest rate swap in June 2017, in anticipation of the issuance of the 2032 Notes. The interest rate swap had a notional amount of $150,000,000 to hedge the risk of changes in the semi-annual interest rate payments attributable to changes in the benchmark interest rate during the several days leading up to the issuance of the 2032 Notes. Upon pricing of the 2032 Notes, the derivative instrument was settled resulting in a gain of approximately $3,098,000, which was reflected in accumulated other comprehensive income (“AOCI”). Approximately $2,114,000 and $198,000 were allocated to debt issuance costs and the debt discount. The debt issuance costs and the debt discount were recorded on the consolidated balance sheet within long-term debt as a contra-liability. The unamortized portion of the debt issuance costs and debt discount was $2,103,000 and $197,000, respectively, at August 31, 2017.

We maintain a $500,000,000 multi-year revolving credit facility (the “Credit Facility”) with a group of lenders that matures in April 2020. Borrowings under the Credit Facility typically have maturities of less than one year. 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 rate or Fed Funds rate. The applicable margin is determined by our credit rating. There were no borrowings outstanding under the Credit Facility at August 31, 2017. As discussed in “NOTE E – Guarantees,” we provided $15,662,000 in letters of credit for third-party beneficiaries as of August 31, 2017. While not drawn against at August 31, 2017, $14,050,000 of these letters of credit were issued against availability under the Credit Facility, leaving $485,950,000 available under the Credit Facility at August 31, 2017.

We also maintain a $100,000,000 revolving trade accounts receivable securitization facility (the “AR Facility”) that matures in January 2018. 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. As of August 31, 2017, no undivided ownership interests in this pool of accounts receivable had been sold.

Stock-Based Compensation

NOTE I – Stock-Based Compensation

Non-Qualified Stock Options

During the three months ended August 31, 2017, we granted non-qualified stock options covering a total of 90,200 common shares under our stock-based compensation plans. The option price of $47.76 per share was equal to the market price of the underlying common shares at the grant date. The fair value of these stock options, based on the Black-Scholes option-pricing model, calculated at the grant date, was $14.99 per share. The calculated pre-tax stock-based compensation expense for these stock options, after an estimate for forfeitures, is $1,203,000 and 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	1.81	%
Expected volatility	36.65	%
Risk-free interest rate	1.98	%
Expected term (years)	6.0

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.

Service-Based Restricted Common Shares

During the three months ended August 31, 2017, we granted an aggregate of 122,400 service-based restricted common shares under our stock-based compensation plans. The fair value of these restricted common shares was equal to the weighted average closing market price of the underlying common shares on the respective dates of grant, or $47.81 per share. The calculated pre-tax stock-based compensation expense for these restricted common shares, after an estimate for forfeitures, is $5,208,000 and will be recognized on a straight-line basis over the three-year service-based vesting period.

Performance Share Awards

We have awarded performance shares to certain key employees under our stock-based compensation plans. These performance shares are earned based on the level of achievement with respect to corporate targets for cumulative corporate economic value added, earnings per share growth and, in the case of business unit executives, business unit operating income targets for the three-year periods ending May 31, 2018, 2019 and 2020. These performance share awards will be paid, to the extent earned, in common shares of the Company in the fiscal quarter following the end of the applicable three-year performance period. The fair values of our performance shares are determined by the closing market prices of the underlying common shares at the respective grant dates of the performance shares and the pre-tax stock-based compensation expense is based on our periodic assessment of the probability of the targets being achieved and our estimate of the number of common shares that will ultimately be issued. During the three months ended August 31, 2017, we granted performance share awards covering an aggregate of 54,700 common shares (at target levels). The calculated pre-tax stock-based compensation expense for these performance shares is $2,768,000 and will be recognized over the three-year performance period.

Income Taxes

NOTE J – Income Taxes

Income tax expense for the three months ended August 31, 2017 and 2016 reflected estimated annual effective income tax rates of 30.5% and 31.2%, respectively. The annual effective income tax rates exclude any impact from the inclusion of net earnings attributable to noncontrolling interests in our consolidated statements of earnings. Net earnings attributable to noncontrolling interests are primarily a result of our WSP, Spartan, Worthington Aritas, and TWB consolidated joint ventures. The earnings attributable to the noncontrolling interests in WSP, Spartan and TWB’s U.S. operations do not generate tax expense to Worthington since the investors in WSP, Spartan and TWB’s U.S. operations are taxed directly based on the earnings attributable to them. The tax expense of Worthington Aritas (a foreign corporation) and TWB’s wholly-owned foreign corporations is reported in our consolidated tax expense. 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 2018 could be materially different from the forecasted rate as of August 31, 2017.

Acquisitions

NOTE M – Acquisitions

On June 2, 2017, the Company acquired Amtrol, a leading manufacturer of pressure cylinders and water system tanks with operations in the U.S. and Europe. The total purchase price was $291,921,000 after adjusting for excess working capital and was funded primarily with cash on hand. The net assets became part of the Pressure Cylinders operating segment at closing, with the well water and expansion tank operations aligning under the consumer products business and the refrigerant, liquid propane and industrial and specialty gas operations aligning under the industrial products business. Total acquisition-related expenses were $3,568,000 of which $1,568,000 was incurred during the three months ended August 31, 2017.

The information included herein has been prepared based on the preliminary allocation of the purchase price using estimates of the fair value and useful lives of the assets acquired and liabilities assumed. The purchase price allocation is subject to further adjustment until all pertinent information regarding the assets acquired and liabilities assumed are fully evaluated by the Company, including but not limited to, the fair value accounting, legal and tax matters, obligations, and deferred taxes.

The assets acquired and liabilities assumed were recognized at their preliminary acquisition-date fair values, with goodwill representing the excess of the purchase price over the fair value of the net identifiable assets acquired. In connection with the acquisition, we identified and valued the following identifiable intangible assets:

(in thousands)	Amount		Useful Life (Years)
Category
Customer relationships	$	90,800		14-17
Trade names		62,200		Indefinite
Technology		13,000		15-16
Total acquired identifiable intangible assets	$	166,000

The purchase price includes the fair values of other assets that were not identifiable, not separately recognizable under accounting rules (e.g., assembled workforce) or of immaterial value. The purchase price also includes a going-concern element that represents our ability to earn a higher rate of return on this group of assets than would be expected on the separate assets as determined during the valuation process. This additional investment value resulted in goodwill, which is not expected to be deductible for income tax purposes.

The following table summarizes the consideration transferred for the assets of Amtrol and the preliminary fair value assigned to the assets acquired and liabilities assumed at the acquisition date:

(in thousands)
Cash	$	6,893
Accounts receivable		40,212
Inventories		37,249
Prepaid expenses		981

The Company’s results of operations for the three months ended August 31, 2017 included the operating results of Amtrol since the date of acquisition. Net sales and operating loss of Amtrol were $57,346,000 and $2,611,000, respectively, for the three months ended August 31, 2017. The following unaudited pro forma information presents consolidated financial information as if Amtrol had been acquired at the beginning of fiscal 2017. Depreciation and amortization expense included in the pro forma results reflect the preliminary acquisition-date fair values assigned to the definite-lived intangible assets and fixed assets of Amtrol assuming a June 1, 2016 acquisition date. Adjustment has also been made for acquisition-related costs incurred in each period presented. Pro forma results for the three months ended August 31, 2017, have also been adjusted to remove the impact of the acquisition-date fair value adjustments to inventories and accrued severance costs related to headcount reductions at Amtrol initiated during the current period, as discussed in “NOTE C – Restructuring and Other Expense.” The pro forma adjustments noted above have been adjusted for the applicable income tax impact. The pro forma information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition had taken place at such time.

Derivative Instruments and Hedging Activities

Aug. 31, 2017

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, foreign currency exchange rate 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.

Foreign Currency Exchange Risk Management – We conduct business in several major international currencies and are therefore subject to risks associated with changing foreign currency exchange rates. We enter into various contracts that change in value as foreign currency exchange rates change to manage this exposure. Such contracts limit exposure to both favorable and unfavorable currency exchange rate fluctuations. The translation of foreign currencies into United States dollars also subjects us to exposure related to fluctuating currency 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 contracts 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. We have credit support agreements in place with certain counterparties to limit our credit exposure. These agreements require either party to post cash collateral if its cumulative market position exceeds a predefined liability threshold. Amounts posted to the margin accounts accrue interest at market rates and are required to be refunded in the period in which the cumulative market position falls below the required threshold. 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.

The following table summarizes the fair value of our derivative instruments and the respective line in which they were recorded in the consolidated balance sheet at August 31, 2017:

	Asset Derivatives				Liability Derivatives
(in thousands)	Balance Sheet Location		Fair Value		Balance Sheet Location		Fair Value

The amounts in the table above reflect the fair value of the Company’s derivative contracts on a net basis. Had these amounts been recognized on a gross basis, the impact would have been a $42,000 increase in receivables with a corresponding increase in accounts payable.

The amounts in the table above reflect the fair value of the Company’s derivative contracts on a net basis. Had these amounts been recognized on a gross basis, the impact would have been a $100,000 increase in receivables with a corresponding increase in accounts payable.

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 OCI and reclassified into earnings in the same line 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 August 31, 2017:

The estimated net amount of the losses recognized in AOCI at August 31, 2017 expected to be reclassified into net earnings within the succeeding twelve months is $5,666,000 (net of tax of $3,425,000). This amount was computed using the fair value of the cash flow hedges at August 31, 2017, and will change before actual reclassification from other comprehensive income to net earnings during the fiscal years ending May 31, 2018 and May 31, 2019.

Economic (Non-designated) Hedges

We enter into foreign currency exchange contracts to manage our foreign currency exchange rate 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.

The following table summarizes our economic (non-designated) derivative instruments outstanding at August 31, 2017:

(in thousands)	Notional Amount		Maturity Date(s)
Commodity contracts	$	20,346	September 2017 - February 2019
Foreign exchange contracts		4,921	September 2017

The following table summarizes the gain (loss) recognized in earnings for economic (non-designated) derivative financial instruments during the three months ended August 31, 2017 and 2016:

Fair Value

3 Months Ended

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	–	Inputs other than quoted prices included within Level 1 that are observable for the assets and liabilities, either directly or indirectly.
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 August 31, 2017, our assets and liabilities measured at fair value on a recurring basis were as follows:

(in thousands)	Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Totals
Assets
Derivative contracts (1)	$	-	$	9,079	$	-	$	9,079

Contingent consideration obligation (2)		-		-		593		593
Total liabilities	$	-	$	342	$	593	$	935

At May 31, 2017, our assets and liabilities measured at fair value on a recurring basis were as follows:

(in thousands)	Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Totals

Contingent consideration obligation (2)		-		-		585		585
Total liabilities	$	-	$	1,142	$	585	$	1,727

(1) The fair value of our derivative instruments 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.

(2) The fair value of the contingent consideration obligation is determined using a probability weighted cash flow approach based on management’s projections of future cash flows of the acquired business. The fair value measurement was based on Level 3 inputs not observable in the market.

The fair value of non-derivative financial instruments included in the carrying amounts of cash and cash equivalents, receivables, notes receivable, income taxes receivable, other assets, 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 $835,414,000 and $618,059,000 at August 31, 2017 and May 31, 2017, respectively. The carrying amount of long-term debt, including current maturities, was $780,162,000 and $578,487,000 at August 31, 2017 and May 31, 2017, respectively.

Recently Adopted Accounting Standards

Recently Adopted Accounting Standards

In July 2015, amended accounting guidance was issued regarding the measurement of inventory. The amended guidance requires that inventory accounted for under the first-in, first-out (FIFO) or average cost methods be measured at the lower of cost and net realizable value, where net realizable value represents the estimated selling price of inventory in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The amended guidance has no impact on inventory accounted for under the last-in, first-out (LIFO) or retail inventory methods. The Company adopted this amended guidance on a prospective basis effective June 1, 2017. The adoption of this guidance did not impact our consolidated financial position or results of operations.

Recently Issued Accounting Standards

Recently Issued Accounting Standards

In May 2014, new accounting guidance was issued that replaces most existing revenue recognition guidance under U.S. GAAP. The new guidance requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. Subsequently, additional guidance was issued on several areas including guidance intended to improve the operability and understandability of the implementation of principal versus agent considerations and clarifications on the identification of performance obligations and implementation of guidance related to licensing. The new guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The guidance permits the use of either the retrospective or cumulative effect transition method. We are in the process of evaluating the effect this guidance will have on the presentation of our consolidated financial statements and related disclosures. While we have not yet identified any material changes in the timing of revenue recognition, our evaluation is ongoing and not complete. We plan to adopt the new guidance in the first quarter of fiscal 2019. The Company will continue to monitor any modifications, clarifications, and interpretations by the FASB that may impact its conclusions.

In February 2016, new accounting guidance was issued that replaces most existing lease accounting guidance under U.S. GAAP. Among other changes, the new guidance requires that lease assets and liabilities be recognized on the balance sheet by lessees for those leases classified as operating leases under previous guidance. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted, and the change is to be applied using a modified retrospective approach as of the beginning of the earliest period presented. We are in the process of evaluating the effect this guidance will have on our consolidated financial position, results of operations and cash flows, and we have not determined the effect of the new guidance on our ongoing financial reporting.

In June 2016, new accounting guidance was issued related to the measurement of credit losses on financial instruments. The new guidance changes the impairment model for most financial assets to require measurement and recognition of expected credit losses for financial assets held. The new guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and we have not determined the effect of the new guidance on our ongoing financial reporting.

In August 2016, amended accounting guidance was issued to clarify the proper cash flow presentation of certain specific types of cash payments and cash receipts. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position, results of operations and cash flows, and we have not determined the effect of the amended guidance on our ongoing financial reporting.

In October 2016, amended accounting guidance was issued that requires the income tax consequences of an intra-entity transfer of an asset other than inventory to be recognized when the transfer occurs. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position, results of operations and cash flows, and have not determined the effect of the amended guidance on our ongoing financial reporting.

In November 2016, amended accounting guidance was issued that requires amounts generally described as restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a material impact on our consolidated cash flows.

In January 2017, amended accounting guidance was issued to clarify the definition of a business to provide additional guidance to assist in evaluating whether transactions should be accounted for as an acquisition (or disposal) of either an asset or business. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a material impact on our consolidated financial position or results of operations.

In January 2017, amended accounting guidance was issued to simplify the goodwill impairment calculation, by removing Step 2 of the goodwill impairment test. Goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of the goodwill. The amended guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and have not determined the effect on our ongoing financial reporting.

In March 2017, amended accounting guidance was issued that requires an employer to report the service cost component of pension and postretirement benefits in the same line as other current employee compensation costs. Additionally, other components of net benefit cost are to be presented in the income statement separately from the service cost component and outside of income from operations. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and have not determined the effect on our ongoing financial reporting.

In May 2017, amended accounting guidance was issued to provide guidance about which changes to the terms or conditions of a share-based payment award require application of modification accounting. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a material impact on our consolidated financial position or results of operations.

In August 2017, amended accounting guidance was issued that modifies hedge accounting by making more hedge strategies eligible for hedge accounting, amending presentation and disclosure requirements, and changing how companies assess effectiveness. The intent is to simplify application of hedge accounting and increase transparency of information about an entity’s risk management activities. The amended guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and have not determined the effect on our ongoing financial reporting.

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 OCI and reclassified into earnings in the same line 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.

[1] The fair value of our derivative instruments 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.

[2] The fair value of the contingent consideration obligation is determined using a probability weighted cash flow approach based on management's projections of future cash flows of the acquired business. The fair value measurement was based on Level 3 inputs not observable in the market.
