AIRGAS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

(1) BASIS OF PRESENTATION

The consolidated financial statements include the accounts of Airgas, Inc. and its subsidiaries (“Airgas” or the “Company”). Intercompany accounts and transactions are eliminated in consolidation. The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). These consolidated financial statements do not include all disclosures required for annual financial statements. These consolidated financial statements should be read in conjunction with the complete disclosures contained in the Company’s audited consolidated financial statements for the fiscal year ended March 31, 2012.

The preparation of financial statements in accordance with GAAP requires the use of estimates. The consolidated financial statements reflect, in the opinion of management, reasonable estimates and all adjustments necessary to present fairly the Company’s results of operations, financial position and cash flows for the periods presented. The interim operating results are not necessarily indicative of the results to be expected for the entire year.

Effective January 1, 2012, the Company changed its method of accounting for the portion of its hardgoods inventory valued using the last-in, first-out (“LIFO”) method to the average-cost method. The Company applied this change in accounting principle through retrospective application to the prior year’s consolidated financial statements. The impact of the change was immaterial.

(2) ACQUISITIONS AND DIVESTITURES

Acquisitions

Acquisitions have been recorded using the acquisition method of accounting and accordingly, results of their operations have been included in the Company’s consolidated financial statements since the effective date of each respective acquisition.

During the six months ended September 30, 2012, the Company purchased eight businesses with historical annual sales of approximately $19 million. A total of $18.7 million in cash was paid for the eight businesses and for the settlement of holdback liabilities and payments related to contingent consideration arrangements associated with prior year acquisitions. Transaction and other integration costs incurred during the six months ended September 30, 2012 were $0.7 million and were included in selling, distribution and administrative expenses in the Company’s Consolidated Statement of Earnings. These acquisitions contributed approximately $4 million in net sales for the six months ended September 30, 2012. The acquired businesses complement the Company’s portfolio of products and services while expanding the Company’s geographic coverage.

The Company negotiated the respective purchase prices of the businesses based on the expected cash flows to be derived from their operations after integration into the Company’s existing distribution network and production locations. The acquisition purchase price is allocated based on the fair values of the assets acquired and liabilities assumed, which are based on third-party appraisals and management estimates. Fiscal 2013 purchase price allocations are substantially complete, with the exception of certain tangible assets associated with two acquisitions that were purchased in August 2012 as the Company finalizes appraisals and other analyses. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed related to fiscal 2013 acquisitions, as well as adjustments to finalize the valuations of certain prior year acquisitions.

(In thousands)	Distribution Business Segment			All Other Operations Business Segment			Total

contractual amounts receivable. Goodwill associated with fiscal 2013 acquisitions was $5.7 million and is deductible for income tax purposes. Goodwill largely consists of expected synergies resulting from the acquisitions, including the expansion of geographical coverage that will facilitate the sale of industrial, medical, and specialty gases and related supplies. Intangible assets related to fiscal 2013 acquisitions represent customer relationships and non-competition agreements and amounted to $3.5 million and $2.7 million, respectively. See Note 4 for further information on goodwill and intangible assets.

Pro forma results of operations for these acquisitions have not been presented since the impact is not material to the Company’s Consolidated Statements of Earnings, either individually or in aggregate.

Divestitures

On June 1, 2012, the Company divested the assets and operations of five branch locations in western Canada. The Company realized a gain on the sale of $6.8 million ($5.5 million after tax) recorded in “Other income (expense), net” in its Consolidated Statement of Earnings. The operations were included in the Distribution business segment and contributed net sales that were not material to the Company’s consolidated earnings. Proceeds from the sale were used primarily to pay down outstanding debt under the Company’s multi-currency revolving credit line.

(4) GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill

Goodwill represents the excess of the purchase price of an acquired entity over the amounts assigned to the assets acquired and liabilities assumed in a business combination. The valuations of assets acquired and liabilities assumed from certain recent acquisitions are based on preliminary estimates of fair value and are subject to revision as the Company finalizes appraisals and other analyses. Changes in the carrying amount of goodwill by business segment for the six months ended September 30, 2012 were as follows:

(In thousands)	Distribution Business Segment			All Other Operations Business Segment		Total
Balance at March 31, 2012	$	969,394		$	194,409	$	1,163,803

Other intangible assets primarily consist of customer relationships, which are amortized over the estimated benefit periods which range from seven to 17 years, and non-competition agreements, which are amortized over the terms of the agreements. The determination of the estimated benefit periods associated with customer relationships is based on an analysis of historical customer sales attrition information and other customer-related factors at the date of acquisition. There are no expected residual values related to these intangible assets. The Company evaluates the estimated benefit periods and recoverability of its intangible assets when facts and circumstances indicate that the lives may not be appropriate and/or the carrying values of the assets may not be recoverable. If the carrying value is not recoverable, impairment is measured as the amount by which the carrying value exceeds its estimated fair value. Fair value is generally estimated based on appraised value or other techniques. Estimated future amortization expense by fiscal year is as follows: remainder of fiscal 2013 - $12.4 million; 2014 - $23.2 million; 2015 - $21.6 million; 2016 - $20.1 million; 2017 - $18.2 million; and $109.0 million thereafter.

Impairment Evaluation

In June 2012, the Company re-evaluated the economic viability of a small hospital piping construction business associated with a reporting unit in the Company’s All Other Operations business segment. In accordance with relevant accounting guidance, if events or circumstances exist indicating that it is more likely than not that goodwill may be impaired, the Company is required to perform an interim assessment of the carrying value of goodwill. However, prior to performing the test for goodwill impairment, the Company is required to perform an assessment of the recoverability of the long-lived assets (including amortizing intangible assets) of the business. Long-lived assets are not considered recoverable when the carrying amount of the long-lived asset or asset group exceeds the undiscounted expected future cash flows. If long-lived assets are not recoverable, an impairment loss is recognized to the extent that the carrying amount exceeds fair value.

As a result of the impairment analysis performed on the long-lived assets at this reporting unit, the Company recorded a charge of $1.7 million related to certain of the intangible assets associated with this business during the three months ended June 30, 2012. The charge was reflected in the “Restructuring and other special charges” line item of the Company’s Consolidated Statement of Earnings and was not allocated to the Company’s business segments (see Note 13).

Subsequent to the intangible asset write-down, the Company performed an assessment of the carrying value of goodwill associated with the reporting unit. The assessment did not indicate that the reporting unit’s goodwill was potentially impaired. However, the fair value of the reporting unit was not substantially in excess of its carrying amount, consistent with the Company’s most recent annual goodwill impairment test. The Company will continue to monitor this business and consider additional interim analyses of goodwill as appropriate; however, the amount of goodwill associated with this reporting unit is not material to the Company’s consolidated financial statements. The Company performs its annual impairment assessment of the carrying value of goodwill associated with each of its reporting units as of October 31 of each year.

Money Market Loans

The Company has an agreement with a financial institution to provide access to additional short-term advances not to exceed $35 million. The agreement expires on January 2, 2013, but may be extended subject to renewal provisions contained in the agreement. The advances may be for one to six months with rates at a fixed spread over the corresponding London Interbank Offering Rate (“LIBOR”). At September 30, 2012, there were no advances outstanding under the agreement.

The Company also has an agreement with another financial institution which provides access to short-term advances not to exceed $35 million that expires on July 31, 2013, but may be extended subject to renewal provisions contained in the agreement. The advances are generally overnight or for up to seven days. The amount, term and interest rate of an advance are established through mutual agreement with the financial institution when the Company requests such an advance. At September 30, 2012, there were no advances outstanding under the agreement.

Commercial Paper

The Company participates in a $750 million commercial paper program supported by its $750 million revolving credit facility (see below). This program allows the Company to obtain favorable short-term borrowing rates with maturities that may vary, but will generally not exceed 90 days from the date of issue. The Company has used proceeds from the commercial paper program to pay down amounts outstanding under its revolving credit facility and for general corporate purposes. At September 30, 2012, $329 million was outstanding under the commercial paper program and the average effective interest rate on these borrowings was 0.57%.

Trade Receivables Securitization

The Company participates in a securitization agreement with three commercial banks to which it sells qualifying trade receivables on a revolving basis (the “Securitization Agreement”). The Company’s sale of qualified trade receivables is accounted for as a secured borrowing under which qualified trade receivables collateralize amounts borrowed from the

11

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(UNAUDITED)

commercial banks. Trade receivables that collateralize the Securitization Agreement are held in a bankruptcy-remote special purpose entity, which is consolidated for financial reporting purposes and represents the Company’s only variable interest entity. Qualified trade receivables in the amount of the outstanding borrowing under the Securitization Agreement are not available to the general creditors of the Company. The maximum amount of the Securitization Agreement is $295 million and it bears interest at approximately LIBOR plus 70 basis points. At September 30, 2012, the amount of outstanding borrowing under the Securitization Agreement was $295 million, and it was classified as long-term debt on the Consolidated Balance Sheet. Amounts borrowed under the Securitization Agreement could fluctuate monthly based on the Company’s funding requirements and the level of qualified trade receivables available to collateralize the Securitization Agreement. The Securitization Agreement expires in December 2013 and contains customary events of termination, including standard cross-default provisions with respect to outstanding debt.

Senior Credit Facility

The Company participates in a $750 million Amended and Restated Credit Facility (the “Credit Facility”). The Credit Facility consists of a $650 million U.S. dollar revolving credit line and a $100 million (U.S. dollar equivalent) multi-currency revolving credit line. The maturity date of the Credit Facility is July 19, 2016. Under circumstances described in the Credit Facility, the revolving credit line may be increased by an additional $325 million, provided that the multi-currency revolving credit line may not be increased by more than an additional $50 million.

As of September 30, 2012, the Company had $36 million of borrowings under the Credit Facility, all of which were under the multi-currency revolver. There were no borrowings under the U.S. dollar revolver at September 30, 2012. The Company also had outstanding U.S. letters of credit of $44 million issued under the Credit Facility. U.S. dollar revolver borrowings bear interest at LIBOR plus 125 basis points. The multi-currency revolver bears interest based on a rate of 125 basis points over the Euro currency rate applicable to each foreign currency borrowing. As of September 30, 2012, the average effective interest rate on the multi-currency revolver was 1.67%. In addition to the borrowing spread of 125 basis points for U.S. dollar and multi-currency revolver borrowings, the Company pays a commitment (or unused) fee on the undrawn portion of the Credit Facility equal to 20 basis points per annum.

At September 30, 2012, the financial covenant of the Credit Facility did not restrict the Company’s ability to borrow on the unused portion of the Credit Facility. The Credit Facility contains customary events of default, including, without limitation, failure to make payments, a cross-default to certain other debt, breaches of covenants, breaches of representations and warranties, certain monetary judgments and bankruptcy and ERISA events. In the event of default, repayment of borrowings under the Credit Facility may be accelerated. As of September 30, 2012, $340 million remained available under the Company’s Credit Facility, after giving effect to the borrowings under the commercial paper program backstopped by the Credit Facility, the outstanding U.S. letters of credit and the borrowings under the multi-currency revolver.

The Company also maintains a committed revolving line of credit of up to €8.0 million (U.S. $10.3 million) to fund its operations in France. These revolving credit borrowings are outside of the Company’s Credit Facility. At September 30, 2012, these revolving credit borrowings were €5.1 million (U.S. $6.5 million). The variable interest rates on the French revolving credit borrowings are based on the Euro currency rate plus 125 basis points. As of September 30, 2012, the effective interest rate on the French revolving credit borrowings was 1.32%. This line of credit matures on December 31, 2012.

Senior Notes

At September 30, 2012, the Company had $300 million outstanding of 2.85% senior notes maturing on October 1, 2013 (the “2013 Notes”). The 2013 Notes were issued at a discount with a yield of 2.871%. Interest on the 2013 Notes is payable semi-annually on April 1 and October 1 of each year.

At September 30, 2012, the Company had $400 million outstanding of 4.5% senior notes maturing on September 15, 2014 (the “2014 Notes”). The 2014 Notes were issued at a discount with a yield of 4.527%. Interest on the 2014 Notes is payable semi-annually on March 15 and September 15 of each year.

At September 30, 2012, the Company had $250 million outstanding of 3.25% senior notes maturing on October 1, 2015 (the “2015 Notes”). The 2015 Notes were issued at a discount with a yield of 3.283%. Interest on the 2015 Notes is payable semi-annually on April 1 and October 1 of each year.

At September 30, 2012, the Company had $250 million outstanding of 2.95% senior notes maturing on June 15, 2016 (the “2016 Notes”). The 2016 Notes were issued at a discount with a yield of 2.980%. Interest on the 2016 Notes is payable

semi-annually on June 15 and December 15 of each year.

The 2013, 2014, 2015 and 2016 Notes (collectively, the “Senior Notes”) contain covenants that could restrict the incurrence of liens and limit sale and leaseback transactions. Additionally, the Company has the option to redeem the Senior Notes prior to their maturity, in whole or in part, at 100% of the principal plus any accrued but unpaid interest and applicable make-whole payments.

Senior Subordinated Notes

At September 30, 2012, the Company had $215 million outstanding of 7.125% senior subordinated notes maturing on October 1, 2018 (the “2018 Notes”). Interest on the 2018 Notes is payable semi-annually on April 1 and October 1 of each year. The 2018 Notes have a redemption provision which permits the Company, at its option, to call the 2018 Notes at scheduled dates and prices. The first scheduled optional redemption date is October 1, 2013 at a price of 103.563% of the principal amount.

Other Long-term Debt

The Company’s other long-term debt primarily consists of vendor financing of rental welders, capitalized lease obligations and notes issued to sellers of businesses acquired, which are repayable in periodic installments. At September 30, 2012, other long-term debt totaled $3.4 million with an average interest rate of approximately 6% and an average maturity of approximately one year.

Aggregate Long-term Debt Maturities

The aggregate maturities of long-term debt at September 30, 2012 are as follows:

^(a)  Outstanding borrowings under the Securitization Agreement at September 30, 2012 are reflected as maturing at the agreement’s expiration in December 2013.

The Senior Notes are reflected in the debt maturity schedule at their maturity values rather than their carrying values, which are net of aggregate discounts of $0.7 million at September 30, 2012. The 2013 Notes also include additional carrying value of $5.0 million at September 30, 2012 related to the Company’s fair value hedges — see Note 7 for additional disclosure.

(7) DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

The Company manages its exposure to changes in market interest rates. The Company’s involvement with derivative instruments is limited to highly effective interest rate swap agreements used to manage well-defined interest rate risk exposures and treasury rate lock agreements used to fix the interest rate related to forecasted debt issuances. The Company monitors its positions and credit ratings of its counterparties and does not anticipate non-performance by the counterparties. Interest rate swap and treasury rate lock agreements are not entered into for trading purposes. The Company recognizes derivative instruments as either assets or liabilities at fair value on the Consolidated Balance Sheets. At September 30, 2012, the Company was party to a total of five interest rate swap agreements with an aggregate notional amount of $300 million.

13

Cash Flow Hedges

In anticipation of the issuance of the 2015 Notes, the Company entered into a treasury rate lock agreement in July 2010 with a notional amount of $100 million that matured in September 2010. The treasury rate lock agreement was designated as a cash flow hedge of the semi-annual interest payments associated with the forecasted issuance of the 2015 Notes. When the treasury rate lock agreement matured, the Company realized a loss of $2.6 million ($1.6 million after tax) which was reported as a component within Accumulated Other Comprehensive Income (“AOCI”) and is being reclassified into earnings over the term of the 2015 Notes. For the six months endedSeptember 30, 2012 and 2011, $259 thousand of the loss on the treasury rate lock was reclassified to interest expense. At September 30, 2012, the estimated loss recorded in AOCI on the treasury rate lock agreement that is expected to be reclassified into earnings within the next twelve months is $517 thousand ($326 thousand after tax).

Fair Value Hedges

The Company also has variable interest rate swap agreements, which are designated as fair value hedges. For derivative instruments designated as fair value hedges, the gain or loss on the derivative as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in current earnings.

At September 30, 2012, the Company had five variable interest rate swaps outstanding with a notional amount of $300 million. These variable interest rates swaps effectively convert the Company’s $300 million of fixed rate 2013 Notes to variable rate debt. At September 30, 2012, these swap agreements required the Company to make variable interest payments based on a weighted average forward rate of 1.21% and receive fixed interest payments from the counterparties based on a fixed rate of 2.85%. The maturity of these fair value swaps coincides with the maturity date of the Company’s 2013 Notes in October 2013. During the six months ended September 30, 2012, the fair value of the variable interest rate swaps decreased by $1.8 million to an asset of $4.9 million and was recorded in other non-current assets. The corresponding decrease in the carrying value of the 2013 Notes caused by the hedged risk was $1.8 million and was recorded in long-term debt. The Company records the gain or loss on the hedged item (i.e., the 2013 Notes) and the gain or loss on the variable interest rate swaps in interest expense. The net gain or loss recorded in earnings as a result of hedge ineffectiveness related to the designated fair value hedges was immaterial for the three and six months ended September 30, 2012 and 2011.

(8) FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities recorded at fair value are classified based upon the level of judgment associated with the inputs used to measure their fair value. The hierarchical levels related to the subjectivity of the valuation inputs are defined as follows:

• Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities at the measurement date.

• Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable, either directly or indirectly, through corroboration with observable market data at the measurement date.

• Level 3 inputs are unobservable inputs that reflect management’s best estimate of the assumptions (including assumptions about risk) that market participants would use in pricing the asset or liability at the measurement date.

The carrying value of cash, trade receivables, other current receivables, trade payables and other current liabilities (e.g., deposit liabilities, cash overdrafts, etc.) approximates fair value.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Assets and liabilities measured at fair value on a recurring basis at September 30, 2012 and March 31, 2012 are categorized in the tables below based on the lowest level of significant input to the valuation. During the periods presented, there were no transfers between fair value hierarchical levels.

The following is a general description of the valuation methodologies used for financial assets and liabilities measured at fair value:

Deferred compensation plan assets and corresponding liabilities — The Company’s deferred compensation plan assets consist of open-ended mutual funds (Level 1) and are included within other non-current assets on the Consolidated Balance Sheets. The Company’s deferred compensation plan liabilities are equal to the plan’s assets and are included within other non-current liabilities on the Consolidated Balance Sheets. Gains or losses on the deferred compensation plan assets are recognized as other income (expense), net, while gains or losses on the deferred compensation plan liabilities are recognized as compensation expense in the Consolidated Statements of Earnings.

Derivative assets — interest rate swap agreements — The Company’s variable interest rate swap agreements are with highly rated counterparties, are designated as fair value hedges and effectively convert the Company’s fixed rate 2013 Notes to variable rate debt. The swap agreements are valued using an income approach that relies on observable market inputs such as interest rate yield curves and treasury spreads (Level 2). Expected future cash flows are converted to a present value amount based upon market expectations of the changes in these interest rate yield curves. The fair values of the Company’s interest rate swap agreements are included within other non-current assets on the Consolidated Balance Sheets. See Note 7 for additional derivatives disclosures.

Contingent consideration liability — As part of the consideration for a fiscal 2011 acquisition, the Company has an arrangement in place whereby future consideration in the form of cash may be transferred to the seller contingent upon the achievement of certain earnings targets. The fair value of the contingent consideration arrangement was estimated using the income approach with inputs that are not observable in the market. Key assumptions include a discount rate commensurate with the level of risk of achievement, time horizon and other risk factors, and probability adjusted earnings growth, all of which the

Company believes are appropriate and representative of market participant assumptions. Of the total liability for the contingent consideration arrangement at September 30, 2012, $1.7 million is included within other non-current liabilities while the remainder is included within accrued expenses and other current liabilities on the Consolidated Balance Sheet. The impact on the Company's earnings as a result of the contingent consideration arrangement for the three and six months ended September 30, 2012 was immaterial.

Changes in the fair value of recurring fair value measurements using significant unobservable inputs (Level 3) for the six months ended September 30, 2012 were as follows (in thousands):

Balance at March 31, 2012	$	2,512
Contingent consideration liability recorded	—
Settlements made during the period	(140		)
Adjustments to fair value measurement	122
Balance at September 30, 2012	$	2,494

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Certain assets and liabilities are measured at fair value on a nonrecurring basis in periods subsequent to initial recognition. Assets measured at fair value on a nonrecurring basis during the six months ended September 30, 2012 and 2011 are categorized in the table below based on the lowest level of significant input to the valuation, and are based on amounts as measured at the time of adjustment. There were no liabilities measured at fair value on a nonrecurring basis during the six months ended September 30, 2012 or 2011.

In June 2012, the Company re-evaluated the economic viability of a small hospital piping construction business. As a result of an impairment analysis performed on the assets at this reporting unit, the Company recorded a charge of $1.7 million related to certain of the intangible assets associated with this business for the six months ended September 30, 2012, which was reflected in the “Restructuring and other special charges” line item of the Company’s Consolidated Statement of Earnings for the six months ended September 30, 2012. The Company used a variation of the income approach, namely the excess earnings method, to estimate the fair value of the intangible assets associated with the business. Under this approach, an intangible asset’s fair value is estimated to be the present value of the incremental after-tax cash flows attributable solely to the intangible asset over its remaining useful life. Key inputs in this model include the cash flow forecast, discount rate, contributory asset charges and tax amortization benefits. As of the evaluation date, the remeasured other intangible assets related to this reporting unit totaled $0.5 million.

In September 2011, the Company performed an evaluation of the recoverability of the fixed assets related to one of its liquid carbon dioxide (“CO₂”) plants. This evaluation was based upon the receipt of notice that a supplier’s hydrogen plant, which generates carbon dioxide as a by-product that serves as the feedstock for the Company's co-located liquid carbon dioxide plant, will cease operations in calendar year 2013. As a result of the analysis, the Company remeasured the fixed assets of its

17

AIRGAS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(UNAUDITED)

liquid carbon dioxide plant and recognized an impairment charge of $2.5 million which was reflected in the “Restructuring and other special charges” line item of the Company’s Consolidated Statement of Earnings for the three and six months ended September 30, 2011. The remeasured plant fixed assets totaled $8.8 million at the date of evaluation and were included within plant and equipment on the Company’s Consolidated Balance Sheet. The Company used an income approach to estimate the fair value of the plant assets based on significant unobservable inputs (Level 3). Factors such as expected future revenues and margins, the likelihood of asset redeployment and the length of the remaining operating term were considered in determining the future cash flows of the plant assets.

The assets and asset groups described above will not be remeasured at fair value on a recurring basis; however, they are still subject to fair value measurements to test for recoverability of the carrying amounts should future conditions warrant an evaluation.

Fair Value of Debt

The carrying value of debt, which is reported on the Company’s Consolidated Balance Sheets, generally reflects the cash proceeds received upon its issuance, net of subsequent repayments, plus the impact of the Company’s fair value hedges. The fair value of the Company’s variable interest rate revolving credit borrowings disclosed in the table below was estimated based on observable forward yield curves and credit spreads management believes a market participant would assume for these facilities under market conditions as of the balance sheet date (Level 2). The fair values of the fixed rate notes disclosed below were determined based on quoted prices from the broker/dealer market, observable market inputs for similarly termed treasury notes adjusted for the Company’s credit spread and inputs management believes a market participant would use in determining imputed interest for obligations without a stated interest rate (Level 2). The fair values of the securitized receivables and the commercial paper approximate their carrying values.

On August 14, 2012, the Company's stockholders approved the Second Amended and Restated 2006 Equity Incentive Plan, which included, among other things, an increase in the maximum number of shares available for issuance under the plan from 5.8 million to 9.8 million. A total of 4.9 million shares of common stock were available for grant under the Amended and Restated 2006 Equity Incentive Plan as of September 30, 2012.

As of September 30, 2012, $49.2 million of unrecognized non-cash compensation expense related to non-vested stock options is expected to be recognized over a weighted-average vesting period of 1.9 years.

Employee Stock Purchase Plan

The Company’s Employee Stock Purchase Plan (the “ESPP”) encourages and assists employees in acquiring an equity interest in the Company. As of September 30, 2012, the ESPP had 1.5 million shares of Company common stock available for issuance.

Compensation expense is measured based on the fair value of the employees’ option to purchase shares of common stock at the grant date and is recognized over the future periods in which the related employee service is rendered. The fair value per share of employee options to purchase shares under the ESPP was $16.72 and $13.16 for the six months endedSeptember 30, 2012 and 2011, respectively. The fair value of the employees’ option to purchase shares of common stock was estimated using the Black-Scholes model.

(11) EARNINGS PER SHARE

Basic earnings per share is calculated by dividing net earnings by the weighted average number of shares of the Company’s common stock outstanding during the period. Outstanding shares consist of issued shares less treasury stock. Diluted earnings per share is calculated by dividing net earnings by the weighted average common shares outstanding adjusted for the dilutive effect of common stock equivalents related to stock options and the Company’s ESPP.

Outstanding stock options that are anti-dilutive are excluded from the Company’s diluted earnings per share computation. There were approximately 1.9 million and 2.0 million shares covered by outstanding stock options that were not dilutive for the three months ended September 30, 2012 and 2011, respectively. There were approximately 1.4 million and 1.7 million shares covered by outstanding stock options that were not dilutive for the six months ended September 30, 2012 and 2011, respectively.

The table below presents the computation of basic and diluted weighted average common shares outstanding for the three and six months ended September 30, 2012 and 2011:

	Three Months Ended		Six Months Ended
	September 30,		September 30,
(In thousands)	2012	2011	2012	2011

Diluted shares outstanding	78,892	77,262	78,860	78,672

(12) COMMITMENTS AND CONTINGENCIES

Litigation

The Company is involved in various legal and regulatory proceedings that have arisen in the ordinary course of business and have not been fully adjudicated. These actions, when ultimately concluded and determined, will not, in the opinion of management, have a material adverse effect upon the Company’s consolidated financial condition, results of operations or liquidity.

(13) SUMMARY BY BUSINESS SEGMENT

Business segment information for the Company’s Distribution and All Other Operations business segments is presented below for the three and six months ended September 30, 2012 and 2011. Business segment operating results for the prior periods were adjusted for the retrospective application of the LIFO-to-average-cost change in accounting principle implemented during the year ended March 31, 2012. Although corporate operating expenses are generally allocated to each business segment based on sales dollars, the Company reports expenses (excluding depreciation) related to the implementation of its SAP system and the Company’s withdrawal from various multi-employer pension plans (“MEPPs”) under selling, distribution and administrative expenses in the “Eliminations and Other” column below. Additionally, the Company’s

restructuring and other special charges and the legal, professional and other costs (benefits) incurred as a result of the Air Products & Chemicals, Inc. (“Air Products”) unsolicited takeover attempt are not allocated to the Company’s business segments. These costs (benefits) are also reflected in the “Eliminations and Other” column below. Corporate assets have been allocated to the Distribution business segment, intercompany sales are recorded on the same basis as sales to third parties, and intercompany transactions are eliminated in consolidation. Management utilizes more than one measurement and multiple views of data to measure segment performance and to allocate resources to the segments. However, the predominant measurements are consistent with the Company’s consolidated financial statements and accordingly, are reported on the same basis below.

Restructuring Costs

In May 2011, the Company announced the alignment of its twelve regional distribution companies into four new divisions, and the consolidation of its regional company accounting and certain administrative functions into four newly created Business Support Centers (“BSCs”). Additionally, the Company initiated a related change in its legal entity structure on January 1, 2012 whereby the majority of Airgas’ distribution businesses have merged or will merge into a single limited liability company (“LLC”) of which the Company is the sole member. Each of the Company’s twelve regional distribution companies operated (prior to conversion to SAP) or operates its own accounting and administrative functions. Enabled by the Company’s conversion to a single information platform across all of its regional companies as part of the SAP implementation, the restructuring will allow Airgas to more effectively utilize its resources across regional company boundaries and to form an operating structure that will help Airgas leverage the full benefits of its new SAP platform.

During the three and six months ended September 30, 2012, the Company recorded $0.3 million and $0.8 million, respectively, in restructuring costs. During the prior year period, the Company recorded $13.3 million in restructuring costs related to severance benefits to be paid out through fiscal 2014, all of which were recorded in the three months ended June 30, 2011.

The activity in the accrued liability balances associated with the restructuring plan was as follows for the six months ended September 30, 2012:

(In thousands)	Severance Costs			Facility Exit and Other Costs			Total
Balance at March 31, 2012	$	13,138		$	990		$	14,128

(UNAUDITED)

expenses and other current liabilities and $1.0 million was included in other non-current liabilities on the Company’s Consolidated Balance Sheet. The restructuring costs were not allocated to the Company’s business segments (see Note 13).

Other Related Costs

For the three and six months ended September 30, 2012, the Company also incurred $2.1 million and $5.6 million, respectively, of other costs related to the divisional realignment and LLC restructuring. These costs primarily related to transition staffing for the BSCs, legal costs and other expenses associated with the Company’s organizational and legal entity changes.

The realignment is expected to be completed by the end of fiscal 2013. The Company expects to incur additional restructuring and other related costs, primarily related to transition staffing, legal and relocation costs, of approximately $5 million for the remainder of the fiscal year.

Asset Impairment Charges

The Company recorded special charges of $1.7 million and $2.5 million related to asset impairments during the six months ended September 30, 2012 and 2011, respectively – see Notes 4 and 8 for further information.

(16) UNSOLICITED TAKEOVER ATTEMPT

On February 11, 2010, Air Products and Chemicals, Inc.'s (“Air Products”) initiated an unsolicited tender offer for all of the Company’s outstanding shares of common stock. In connection with this unsolicited tender offer, Air Products filed an action against the Company and members of its Board in the Delaware Court of Chancery. On February 15, 2011, the Delaware Court of Chancery denied in their entirety all requests for relief by Air Products and dismissed with prejudice all claims asserted against the Company and its directors. Air Products promptly terminated its unsolicited tender offer and no appeal of the Court’s decision was filed. In connection with the unsolicited tender offer and related litigation, the Company incurred on a cumulative basis a net $60.0 million of legal and professional fees and other costs. During the three months ended June 30, 2011, the Company recognized benefits of $6.7 million from lower than previously estimated net costs related to the unsolicited takeover attempt.

(17) SUBSEQUENT EVENTS

On October 23, 2012, the Company announced a program to purchase up to $600 million of its outstanding shares of common stock. As of October 22, 2012, the Company had approximately 77.3 million common shares outstanding. Airgas may repurchase shares from time to time for cash in open market transactions or in privately-negotiated transactions in accordance with applicable federal securities laws. The Company will determine the timing and the amount of any repurchases based on its evaluation of market conditions, share price, and other factors. The stock repurchase program has no pre-established closing date and may be suspended or discontinued at any time.

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

OVERVIEW

Airgas, Inc. and its subsidiaries (“Airgas” or the “Company”) had net sales for the quarter ended September 30, 2012 (“current quarter”) of $1.23 billion compared to $1.19 billion for the quarter ended September 30, 2011 (“prior year quarter”), an increase of 4%. Total same-store sales increased 3%, with hardgoods up 1% and gas and rent up 4%. Acquisitions, net of a divestiture, contributed sales growth of 1% in the current quarter. The same-store sales growth for the current quarter was driven by pricing increases of 4%, partially offset by volume decreases of 1%. The Company’s same-store sales growth was solid, despite moderating business trends across its diversified customer base during the current quarter and in light of the year-over-year impacts of one less selling day and the impact of a disruption within the helium supply chain (see Supply Constraints section below) during the current quarter. Higher pricing reflects a broad-based price increase on gas and rent and on certain hardgoods effective December 1, 2011 and to a lesser extent the September 1, 2012 price increase on cylinder and bulk tank rental rates. The Company recently announced an additional broad-based price increase on gases and hardgoods effective October 1, 2012. The pricing actions were designed to address rising product, operating and distribution costs as well as support ongoing investments in production and distribution capabilities to support and efficiently meet the growing demands of the Company’s customers while fulfilling the safety and security requirements of its industry.

The consolidated gross profit margin (excluding depreciation) in the current quarter was 55.1%, an increase of 160 basis points from the prior year quarter, reflecting margin expansion on gases and hardgoods and a sales mix shift toward higher-margin gas and rent relative to hardgoods.

The Company’s operating income margin decreased to 11.8%, a 20 basis-point decrease from the prior year quarter. Additionally, the current and prior year quarters’ operating income margins were each burdened by 20 basis points of restructuring and other special charges. The current and prior year quarters also included 90 basis points and 70 basis points of negative impact, respectively, from SAP implementation costs and depreciation expense (see “Enterprise Information System” section below).

Net earnings per diluted share increased to $1.03 in the current quarter versus $1.01 in the prior year quarter. Lower helium sales volumes driven by the inability of suppliers to meet their supply commitments to the Company reduced diluted earnings per share by $0.02 in the current quarter compared to the prior year quarter. Additionally, the current quarter’s diluted earnings per share included $0.02 of incremental SAP costs and a year-over-year negative impact of $0.03 due to one less selling day in the current quarter. Net earnings per diluted share in both the current and prior year quarters also included restructuring and other special charges of $0.02 per diluted share. Restructuring and other special charges in each quarter consisted of the following:

	Three Months Ended
	September 30,
Effect on Diluted EPS	2012			2011
Restructuring and other related costs	$	(0.02	)	$	—
Impairment charges	—			(0.02		)
Restructuring and other special charges	$	(0.02	)	$	(0.02	)

Supply Constraints

The global industrial gas industry continues to work through supply constraints related to helium. Disruption in crude helium production overseas and limited liquefied natural gas demand have been the primary causes of the worldwide helium shortage, aggravated by outages and temporary shutdowns at the Federal Helium Reserve and shutdowns at a major private helium source. To help mitigate the financial impact to Airgas, the Company continues to explore alternative sources of helium and has instituted product allocations and price increases related to helium. However, these supply constraints forced the Company to shed non-contract helium customers and to allocate its limited helium supply to contract customers. During the current quarter, the Company’s helium sales significantly decreased driven by the inability of suppliers to meet their supply commitments to the Company, thereby influencing the Company’s volume of helium sales to its own customers.

Diluted earnings per share were reduced by $0.02 in the current quarter as a result of the helium supply disruption. Sales of helium represented approximately 2% and 3% of the Company’s consolidated net sales in the current and prior year quarters, respectively. The Company expects the global helium supply chain to improve in mid calendar 2013, but anticipates the time

25

frame for the Company to regain lost customers and recover from year-over-year headwinds to be longer.

Enterprise Information System

The Company continued its phased, multi-year rollout of its highly-customized SAP enterprise information system during the current quarter. At this stage in the Company’s phased implementation, each of its four BSCs, into which the regional company accounting and administrative functions are being consolidated upon converting to SAP, are firmly in place. Through October 2012, the Company had successfully converted its Safety telesales and hardgoods infrastructure businesses and ten regional distribution companies to the SAP platform. One additional regional distribution company implementation is expected to take place in the third quarter ending December 31, 2012, resulting in eleven of the Company’s twelve regional distribution companies operating on the SAP platform by the end of calendar year 2012. The Company expects that the remaining regional distribution company will be converted in the Company’s fiscal fourth quarter ending March 31, 2013.

With ten out of twelve of its regional distribution companies operating successfully on SAP, the Company believes the implementation risk associated with the remaining business units has been significantly diminished and is beginning to focus more on attaining benefits. As with the implementation of any new enterprise information system, the Company has experienced distractions and disruptions as its associates learn the new system and processes. These have not had a material impact to date on the Company, and the Company will continue to monitor these items carefully going forward. Total implementation costs and depreciation expense related to the SAP system were $0.09 and $0.07 per diluted share for the quarters ended September 30, 2012 and 2011, respectively, and such costs, net of expected benefits, are estimated to be in the range of $0.12 to $0.16 per diluted share for the year ending March 31, 2013. Fiscal 2012 included $0.34 per diluted share of SAP implementation costs and depreciation expense. The Company expects the combination of lower implementation costs and the ramp-up in SAP-related benefits to yield year-over-year earnings accretion of between $0.18 and $0.22 per diluted share in fiscal 2013 above and beyond the Company’s base business performance.

The Company previously quantified the economic benefits expected to be achieved through its implementation of SAP in three key areas: accelerated sales growth through expansion of the telesales platform, price management, and administrative and operating efficiencies. By December 2013, the Company expects these areas alone to have yielded a minimum of $75 million in annual run-rate operating income benefits. Further economic benefits are expected to be identified as the implementation progresses.

New Divisional Alignment and LLC Formation

In May 2011, the Company announced the alignment of its twelve regional distribution companies into four new divisions, and the consolidation of its regional company accounting and certain administrative functions into four newly created BSCs. Additionally, the Company initiated a related change in its legal entity structure on January 1, 2012 whereby the majority of Airgas’ distribution businesses have merged or will merge into a single limited liability company (“LLC”) of which the Company is the sole member. Each of the Company’s twelve regional distribution companies operated (prior to conversion to SAP) or operates its own accounting and administrative functions. Enabled by the Company’s conversion to a single information platform across all of its regional companies as part of the SAP implementation, the restructuring will allow Airgas to more effectively utilize its resources across regional company boundaries and form an operating structure that will help Airgas leverage the full benefits of its new SAP platform.

During the current quarter, the Company recorded restructuring costs of $0.3 million associated with its organization and legal entity changes. Also during the current quarter, the Company incurred $2.1 million of other costs related to the divisional realignment and LLC restructuring. These costs primarily related to transition staffing for the BSCs, legal costs and other expenses associated with the Company’s organizational and legal entity changes. The realignment is expected to be completed by the end of fiscal 2013. The Company expects to incur additional restructuring and other related costs, primarily related to transition staffing, legal and relocation costs, of approximately $5 million for the remainder of the fiscal year.

Stock Repurchase Program

On October 23, 2012, the Company announced a new program to repurchase up to $600 million of its outstanding shares of common stock. The Company may repurchase shares from time to time for cash in open market transactions or in privately-negotiated transactions in accordance with applicable federal securities laws. The Company will determine the timing and the amount of any repurchases based on its evaluation of market conditions, share price and other factors. The stock repurchase program has no pre-established closing date and may be suspended or discontinued at any time. The impact of the October 2012 stock repurchase program has not been included in the Company’s forward-looking guidance.

26

Acquisitions and Divestitures

During the six months ended September 30, 2012, the Company purchased eight businesses with aggregate historical annual sales of more than $19 million.

During the three months ended June 30, 2012, the Company divested the assets and operations of five branch locations in western Canada. The Company realized a gain on the sale of $6.8 million ($5.5 million after tax) recorded in “Other income (expense), net” in its Consolidated Statement of Earnings. The operations were included in the Distribution business segment and contributed net sales that were deemed to be immaterial to the Company’s consolidated earnings.

Fiscal 2013 Outlook

The Company expects earnings per diluted share for the quarter ending December 31, 2012 to be in the range of $1.03 to $1.09 and for fiscal 2013 to be in the range of $4.42 to $4.57. The earnings per diluted share range for fiscal 2013 includes an estimated $0.10 per diluted share of restructuring and other special charges ($0.02 of which are expected in the third quarter), a $0.07 gain related to the sale of businesses in the first quarter, an estimated year-over-year decline of $0.10 from the impact of lost sales due to helium supply constraints ($0.03 of which are expected in the third quarter) and $0.12 to $0.16 per diluted share of implementation costs and depreciation expense, net of expected benefits, associated with the Company’s SAP implementation. The Company expects its same-store sales growth rate for the quarter ending December 31, 2012 to be in the low single digits and for fiscal 2013 to be in the low to mid single digits.

27

RESULTS OF OPERATIONS: THREE MONTHS ENDED SEPTEMBER 30, 2012 COMPARED TO THREE MONTHS ENDED SEPTEMBER 30, 2011

STATEMENT OF EARNINGS COMMENTARY

Results for the prior year quarter and year-to-date periods were adjusted for the retrospective application of a change implemented in the fourth quarter of the prior year in the Company’s method of accounting for the small portion of its hardgoods inventory valued using the last-in, first-out (“LIFO”) to the average-cost method. The impact of this change was immaterial to the operating results for the prior year quarter and year-to-date periods. Business segment information and statement of earnings commentary related to the prior year quarter and year-to-date periods have been recast to reflect the change in accounting principle.

Although corporate operating expenses are generally allocated to each business segment based on sales dollars, the Company reports expenses (excluding depreciation) related to the implementation of its SAP system and the Company’s withdrawal from various multi-employer pension plans (“MEPPs”) under selling, distribution and administrative expenses in the “Other” line item in the tables below. Additionally, the Company's restructuring and other special charges and the legal, professional and other costs (benefits) incurred as a result of the Air Products and Chemicals, Inc. (“Air Products”) unsolicited takeover attempt are not allocated to the Company’s business segments. These costs (benefits) are also reflected in the “Other” line item in the tables below.

Net Sales

Net sales increased 4% to $1.23 billion for the current quarter compared to the prior year quarter, driven by same-store sales growth of 3%. Acquisitions, net of a divestiture, contributed sales growth of 1% in the quarter. Gas and rent same-store sales increased 4% and hardgoods increased 1%. Same-store sales were driven by pricing increases of 4%, partially offset by volume decreases of 1%. Same-store sales and volumes for both gas and rent and hardgoods were reduced by approximately 1% due to one less selling day in the current year quarter versus the prior year quarter, with helium supply constraints also reducing gas volumes by an additional 1%. The Company estimates same-store sales growth based on a comparison of current period sales to prior period sales, adjusted for acquisitions and divestitures. The pro forma adjustments consist of adding acquired sales to, or subtracting sales of divested operations from, prior period sales beginning in the corresponding month in the prior period in which the Company completed the acquisition or divested the operations during the current period, and continuing through the acquisition or divestiture date for subsequent period comparisons.

Strategic products account for approximately 40% of net sales and include safety products, bulk, medical and specialty gases, as well as carbon dioxide and dry ice. The Company has identified these products as strategic because it believes they have good long-term growth profiles relative to the Company’s core industrial gas and welding products due to favorable end customer markets, application development, increasing environmental regulation, strong cross-selling opportunities or a combination thereof. For the current quarter, growth on the sales of strategic products decelerated to 3% over the prior year quarter, driven by broad-based economic softening. Each product category with the strategic products grouping posted sales growth in the 2% to 3% range in the current quarter as compared to the prior year quarter.

Strategic accounts also contributed to the increase in net sales for the quarter. Strategic accounts were up 3% over the prior year quarter, as growth from continued new account signings and cross-selling to existing customers was tempered by broad-based slowing in general activity across most customer segments. The Company’s large metal fabrication customers continued to post the strongest growth, though showing modest deceleration from first quarter growth rates. Strategic account sales in the Company’s retail customer segment experienced a double digit decline from the prior year quarter due to the helium supply disruption. Excluding this impact, strategic accounts grew 4% from the prior year quarter. The strategic accounts program, which now represents more than 20% of net sales, was designed to deliver superior product and service offerings to larger, multi-location customers, and presents the Company with strong cross-selling opportunities.

The table below reflects actual sales and does not include the pro forma adjustments used in calculating the same-store sales metric. The intercompany eliminations represent sales from the All Other Operations business segment to the Distribution business segment.

The Distribution business segment’s principal products include industrial, medical and specialty gases, and process chemicals; cylinder and equipment rental; and hardgoods. Industrial, medical and specialty gases are distributed in cylinders and bulk containers. Rental fees are generally charged on cylinders, dewars (cryogenic liquid cylinders), bulk and micro-bulk tanks, tube trailers and certain welding equipment. Hardgoods generally consist of welding consumables and equipment, safety products, construction supplies and maintenance, repair and operating supplies.

Distribution business segment sales increased 3% compared to the prior year quarter with an increase in same-store sales of 2%. Incremental sales growth from acquisitions, net of a divestiture, contributed sales growth of 1% in the current quarter. Same-store sales growth for the Distribution business segment was driven by price increases of 4%, partially offset by decreased volumes of 2%. The Distribution business segment’s gas and rent same-store sales increased 3%, with pricing up 5% and volumes down 2%. Hardgoods same-store sales increased 1%, with pricing up 3% and volumes down 2%. Distribution business segment same-store sales and volumes for both gas and rent and hardgoods were reduced by approximately 1% due to one less selling day in the current quarter versus the prior year quarter, with helium supply constraints also reducing gas volumes by an additional 1%. The reduction in volumes was broad-based, reflecting an overall slower pace of activity in the industrial economy. The increase in pricing was primarily driven by the broad-based price increase on gas and rent and on certain hardgoods effective December 1, 2011 and to a lesser extent the September 1, 2012 price increase on cylinder and bulk tank rental rates.

Contributing to the increase in the Distribution business segment hardgoods same-store sales were increases in both safety products and the Company’s Radnor^® private-label brand product line. Safety product sales increased 3% in the current quarter from the prior year quarter. Although this compared favorably to the total hardgoods same-store sales increase for the Distribution business segment of 1%, it represented a sharp deceleration from the 11% year-over-year growth in the fiscal first quarter. Sales of the Company’s Radnor^® private-label line were up 1% for the current quarter, consistent with total hardgoods same-store sales growth. Deceleration of sales growth for both safety and Radnor^® brand products was driven by general slowing in activity levels in the Company’s core industrial customer base.

Revenues from the Company’s rental welder business experienced a 29% increase in same-store sales during the current quarter as compared to the prior year quarter due to increased rental demand, reflecting strength in outage work in the oil, gas and chemicals industry, including refineries, and in the power industry.

The All Other Operations business segment consists of six business units. The primary products manufactured and/or distributed are carbon dioxide, dry ice, nitrous oxide, ammonia and refrigerant gases.

The All Other Operations business segment sales increased 7% in total and on a same-store basis compared to the prior year quarter, with incremental sales related to current and prior year acquisitions contributing sales growth of less than 1% in the quarter. The same-store sales increase was primarily driven by increases in refrigerants pricing and by both price and volume in the Company’s ammonia and CO₂ businesses. The Company’s refrigerant gas sales have continued to benefit from increased demand ahead of a potential EPA ruling which would accelerate the phase-out of new production of R-22, the most commonly used refrigerant gas in HVAC systems.

Gross Profits (Excluding Depreciation)

Gross profits (excluding depreciation) do not reflect deductions related to depreciation expense and distribution costs. The Company reflects distribution costs as an element of the line item “Selling, distribution and administrative expenses” and recognizes depreciation on all of its property, plant and equipment in the line item “Depreciation” in its Consolidated Statement of Earnings. Other companies may report certain or all of these costs as elements of their cost of products sold and, as such, the Company’s gross profits (excluding depreciation) discussed below may not be comparable to those of other companies.

Consolidated gross profits (excluding depreciation) increased 7% compared to the prior year quarter, principally due to the sales increase for the current quarter, underlying margin expansion in gases and hardgoods and the sales mix shift to higher

29

margin gas and rent. The consolidated gross profit margin (excluding depreciation) in the current quarter increased 160 basis points to 55.1% compared to 53.5% in the prior year quarter. The increase in consolidated gross profit margin (excluding depreciation) reflects margin expansion in gases and hardgoods, as well as a sales mix shift toward higher-margin gas and rent, as compared to the prior year quarter. Gas and rent represented 63.2% of the Company's sales mix in the current quarter, up from 62.7% in the prior year quarter.

The Distribution business segment’s gross profits (excluding depreciation) increased 6% compared to the prior year quarter. The Distribution business segment’s gross profit margin (excluding depreciation) was 55.8% versus 54.0% in the prior year quarter, an increase of 180 basis points. The increase in the Distribution business segment’s gross profit margin (excluding depreciation) reflects underlying margin improvement on gases and hardgoods and a slight sales mix shift away from lower-margin hardgoods towards higher-margin gases. As a percentage of the Distribution business segment’s sales, gas and rent increased 30 basis points to 58.4% in the current quarter as compared to 58.1% in the prior year quarter.

The All Other Operations business segment’s gross profits (excluding depreciation) increased 10% compared to the prior year quarter. The All Other Operations business segment’s gross profit margin (excluding depreciation) increased 130 basis points to 47.1% in the current quarter from 45.8% in the prior year quarter. The increase in the All Other Operations business segment’s gross profit margin (excluding depreciation) was primarily driven by margin expansion in the Company's refrigerants and CO₂ businesses.

Operating Expenses

Selling, Distribution and Administrative (“SD&A”) Expenses

SD&A expenses consist of labor and overhead associated with the purchasing, marketing and distribution of the Company’s products, as well as costs associated with a variety of administrative functions such as legal, treasury, accounting, tax and facility-related expenses. Consolidated SD&A expenses increased $35 million, or 8%, in the current quarter as compared to the prior year quarter. Contributing to the increase in SD&A expenses were $28 million of normal inflationary increases plus higher variable costs associated with growing sales, such as sales commissions, salaries, production overtime and distribution costs, approximately $4 million of incremental operating costs associated with acquired businesses, net of a divestiture and approximately $3 million of incremental costs associated with the SAP implementation. As a percentage of net sales, SD&A expenses increased to 37.3% in the current quarter from 35.7% in the prior year quarter.

Other	8,618		6,077		2,541
	$	458,301	$	423,437	$	34,864	8	%

SD&A expenses in both the Distribution and All Other Operations business segments increased 8%, compared to the prior year quarter. For both business segments, the increases in SD&A costs were driven by normal inflationary increases plus higher variable costs on sales growth, including sales commissions, salaries, production overtime and distribution costs, and incremental operating costs associated with acquired businesses of $3 million for the Distribution business segment, net of a divestiture and $1 million for the All Other Operations business segment. As a percentage of Distribution business segment net sales, SD&A expenses in the Distribution business segment increased 170 basis points to 37.4% compared to 35.7% in the prior year quarter, primarily driven by the higher variable costs of sales growth noted above. As a percentage of All Other Operations business segment net sales, SD&A expenses in the All Other Operations business were 28.6% compared to 28.4% in the prior year quarter.

SD&A Expenses – Other

Enterprise Information System

The Company continues its phased, multi-year rollout of its highly-customized SAP enterprise information system, whereby business units implement the new system in succession. Through October 2012, the Company had successfully converted its Safety telesales and hardgoods infrastructure businesses and ten regional distribution companies to SAP. The Company continues to prepare for the implementation of SAP at the remainder of its business units. SAP costs incurred by the Company include pre-implementation data conversion and training costs as well as post-implementation monitoring, training and operating activities related to the scheduled business unit rollouts. SAP implementation costs for the current quarter were $8.6 million as compared to $6.1 million in the prior year quarter, reflecting higher than expected costs related to additional post-conversion support costs, including training, travel and overtime in the current quarter. These costs were recorded as SD&A expenses and were not allocated to the Company’s business segments.

Restructuring and Other Special Charges

The following table presents the components of restructuring and other special charges for the current and prior year quarters:

Restructuring and Other Related Costs

As a result of the realignment of the Company’s twelve regional distribution companies into four new divisions, and the consolidation of its regional company accounting and certain administrative functions into four newly created BSCs, the Company recorded $0.3 million in restructuring costs during the current quarter. Also during the current quarter, the Company incurred $2.1 million of other costs related to the divisional realignment and LLC restructuring. These costs primarily related to transition staffing for the BSCs, legal costs and other expenses associated with the Company’s organizational and legal entity changes. The restructuring charges and other related costs were not allocated to the Company’s business segments.

Depreciation and Amortization

Depreciation expense increased $4 million or 7%, to $64.6 million in the current quarter as compared to $60.4 million in the prior year quarter. The increase primarily reflects the additional depreciation expense on capital investments in revenue generating assets to support customer demand (such as cylinders, rental welders and bulk tanks). Amortization expense of $7 million in the current quarter increased $0.5 million from the prior year quarter.

Operating Income

Consolidated operating income of $145 million increased 2% in the current quarter driven by same-store sales growth in both the Distribution and All Other Operations business segments and margin expansion in the All Other Operations business segment, partially offset by nearly $3 million of incremental SAP costs. The current and prior year quarters also included 90 basis points and 70 basis points of negative impact, respectively, from SAP implementation costs and depreciation expense. The consolidated operating income margin decreased 20 basis points to 11.8% from 12.0% in the prior year quarter.

Operating income in the Distribution business segment increased 2% in the current quarter. The Distribution business segment’s operating income margin decreased 10 basis points to 12.4% compared to 12.5% in the prior year quarter. The operating income margin decrease was primarily driven by moderating sales growth and the significant decline in helium sales due to supply constraints.

Operating income in the All Other Operations business segment increased 16% compared to the prior year quarter. The All Other Operations business segment’s operating income margin of 14.2% increased by 100 basis points compared to the operating income margin of 13.2% in the prior year quarter. The increase in the All Other Operations business segment’s operating income was primarily driven by margin expansion in the refrigerants and CO₂ businesses.

Interest Expense, Net

Interest expense, net, was $16 million in the current quarter, representing a decrease of $2 million, compared to the prior year quarter.

Income Tax Expense

The effective income tax rate was 37.9% of pre-tax earnings in the current quarter compared to 37.3% in the prior year quarter. The Company expects the effective income tax rate for fiscal 2013 to be between 37.5% and 38.0% of pre-tax earnings.

Net Earnings

Net earnings per diluted share rose 2% to $1.03 in the current quarter compared to $1.01 in the prior year quarter. Net earnings were $81.0 million compared to $77.9 million in the prior year quarter. Incremental SAP costs, one less selling day and helium supply constraints reduced earnings growth by $0.07 in the aggregate in the current quarter compared to the prior year quarter. Additionally, net earnings per diluted share in both the current and prior year quarters included restructuring and other special charges of $0.02 per diluted share. Restructuring and other special charges in each quarter consisted of the following:

STATEMENT OF EARNINGS COMMENTARY

Net Sales

Net sales increased 6% to $2.5 billion for the six months ended September 30, 2012 (“current period”) compared to the six months ended September 30, 2011 (“prior year period”), driven by same-store sales growth of 5% and incremental sales of 1% contributed by acquisitions, net of a divestiture. Both hardgoods and gas and rent same-store sales increased 5%. Same-store sales were driven by increased volumes of 1% and price of 4%. For the current period, sales of strategic products increased 5% on a same-store basis as compared to the prior year period.

Strategic accounts also contributed to the increase in net sales for the current period. Strategic accounts sales growth of 5% was primarily driven by new account signings and increased activity in the majority of the Company’s customer segments, most notably in the metal fabrication, oil and gas and chemicals segments. Strategic account sales in the Company’s retail customer segment experienced a substantial decline from the prior year period due to the helium supply disruption. Excluding this impact, strategic accounts grew 7% from the prior year period.

Distribution business segment sales increased 5% compared to the prior year period with an increase in same-store sales of 5% and incremental sales of less than 1% contributed by current and prior year acquisitions, net of a divestiture. Same-store sales growth for the Distribution business segment was driven by increased volumes of 1% and price of 4%. The Distribution business segment’s gas and rent same-store sales increased 4%, with volumes down 1% and pricing up 5%. Hardgoods same-store sales increased 5%, with volumes up 2% and pricing up 3%. The increase in pricing was primarily driven by the December 1, 2011 price increase and to a lesser extent the September 1, 2012 price increase on cylinder and bulk tank rental rates.

Sales of strategic gas products sold through the Distribution business segment in the current period increased 4% from the prior year period. Among strategic gas products, bulk gas sales were up 6% on improvement in the industrial manufacturing customer base and new customer signings. Sales of medical gases were up 3% as a result of new business signings and stronger demand across most medical segments. Sales of specialty gases were up 3% driven primarily by higher volumes on improvement in demand for core specialty gases, including EPA protocols.

Contributing to the rise in Distribution business segment hardgoods same-store sales were increases in both safety products and the Company’s Radnor^® private-label brand product line. Safety product sales increased 7% in the current period, comparing favorably to the hardgoods same-store sales increase for the Distribution business segment of 5% and reflecting broad-based improvement in the core safety business, particularly in large industrial production and strategic account customers. The Company’s Radnor^® private-label line was up 6% for the current period, driven by the overall increase in hardgoods volumes.

Revenues from the Company’s rental welder business experienced a 25% increase in same-store sales during the current period as compared to the prior year period due to increased rental demand, reflecting strength in outage work in the oil, gas and chemicals industry, including refineries, and in the power industry.

The All Other Operations business segment sales increased 7% in total and on a same-store basis compared to the prior year period, with incremental sales of less than 1% contributed by current and prior year acquisitions. The same-store sales increase was primarily driven by an increase in refrigerants, CO₂ and ammonia sales, which increased on both a volume and price basis.

Gross Profits (Excluding Depreciation)

Consolidated gross profits (excluding depreciation) increased 8% compared to the prior year period, principally due to the same-store sales increase for the current period. The consolidated gross profit margin (excluding depreciation) in the current period increased 100 basis points to 54.9% compared to 53.9% in the prior year period. The increase in consolidated gross profit margin (excluding depreciation) reflects margin expansion in gas and hardgoods.

Operating Expenses

Selling, Distribution and Administrative (“SD&A”) Expenses

Consolidated SD&A expenses increased $72 million, or 8%, in the current year as compared to the prior year period. Contributing to the increase in SD&A expenses were $58 million of normal inflationary increases plus higher variable costs associated with growing sales, such as sales commissions, salaries, production overtime and distribution costs, approximately $10 million of incremental operating costs associated with acquired businesses, net of a divestiture and $4 million of incremental costs associated with the SAP implementation.

SAP implementation costs for the current period were $18.6 million as compared to $14.4 million in the prior year period.

Multi-employer Pension Plan Withdrawals

As collective bargaining agreements (“CBAs”) came up for renewal, the Company actively negotiated the withdrawal from MEPPs, replacing those retirement plans for CBA employees with defined contribution plans. During the prior year period, the Company incurred MEPP withdrawal charges of $0.9 million, related to the withdrawal from MEPPs under two CBAs. These charges are reflected in selling, distribution and administrative expenses. As of September 30, 2012, the Company has successfully negotiated its withdrawal from all MEPPs in which it previously participated and has fully accrued for the related withdrawal assessments.

Asset Impairments

In June 2012, the Company re-evaluated the economic viability of a small hospital piping construction business, and as a result of an impairment analysis performed on the assets at the associated reporting unit, the Company recorded a charge of $1.7 million related to certain of the intangible assets associated with this business for the six months ended September 30, 2012.

In August 2011, the Company received 24 months notice that a supplier’s hydrogen plant, which generates carbon dioxide as a by-product that serves as the feedstock for the Company’s co-located liquid carbon dioxide plant, will cease operations in calendar year 2013. The Company expects the hydrogen plant to continue to supply the feedstock for its liquid carbon dioxide plant during the intervening period. As a result of an impairment analysis performed on the assets at this location, the Company recorded a charge of $2.5 million during the prior year period.

Unsolicited Takeover Attempt

On February 11, 2010, Air Products initiated an unsolicited tender offer for all of the Company’s outstanding shares of common stock. In connection with this unsolicited tender offer, Air Products filed an action against the Company and members of its Board in the Delaware Court of Chancery. On February 15, 2011, the Delaware Court of Chancery denied in their entirety all requests for relief by Air Products and dismissed with prejudice all claims asserted against the Company and its directors. Air Products promptly terminated its unsolicited tender offer and no appeal of the Court’s decision was filed. In connection with the unsolicited tender offer and related litigation, the Company incurred on a cumulative basis a net $60.0 million of legal and professional fees and other costs. During the prior year period, the Company recognized a $6.7 million benefit from lower than previously estimated net costs related to the Air Products’ unsolicited takeover attempt of Airgas. The net costs and benefits recognized related to the unsolicited takeover attempt were reflected as a separate line item in the Company’s Consolidated Statements of Earnings, and were not allocated to the Company’s business segments.

Depreciation and Amortization

Depreciation expense increased $8 million or 7%, to $129 million in the current period as compared to $121 million in the prior year period. The increase primarily reflects the additional depreciation expense on capital investments in revenue generating assets to support customer demand (such as cylinders and bulk tanks), $0.6 million of incremental depreciation expense related to the SAP enterprise information system and $1 million of additional depreciation expense on capital assets

35

included in acquisitions. Amortization expense of $13 million in the current period was $1 million higher than that of the prior year period.

Operating Income

Consolidated operating income of $297 million increased 6% in the current period driven by operating leverage on organic sales growth, offset by $5 million of incremental SD&A and depreciation expense related to the SAP implementation. The consolidated operating income margin remained consistent at 11.9% in both the current and prior year periods.

Operating income in the Distribution business segment increased 3% in the current period. The Distribution business segment’s operating income margin decreased 30 basis points to 12.4% compared to 12.7% in the prior year period. The operating income margin decrease was driven by moderating sales growth relative to the increase in expenses and the year-over-year decline in helium sales due to supply constraints.

Operating income in the All Other Operations business segment increased 30% compared to the prior year period. The All Other Operations business segment’s operating income margin of 16.4% increased by 280 basis points compared to the operating income margin of 13.6% in the prior year period, primarily driven by margin improvements in the refrigerants, CO₂ and ammonia businesses.

Interest Expense

Interest expense, net, was $32 million in the current period, representing a decrease of $2 million, or 7%, compared to the prior year period. The overall decrease in interest expense, net, resulted primarily from lower average debt balances in the current period as compared to the prior year period.

Other Income (Expense), Net

The increase of $9.4 million in “Other income (expense), net” was primarily driven by the Company’s divestiture of the assets and operations of five branch locations in western Canada. The Company realized a gain of $6.8 million ($5.5 million after tax) on the sale. 

Income Tax Expense

The effective income tax rate was 37.5% of pre-tax earnings in the current period compared to 37.7% in the prior year period. The Company expects the effective income tax rate for fiscal 2013 to be between 37.5% and 38.0% of pre-tax earnings.

Net Earnings

Net earnings per diluted share rose 12% to $2.18 in the current period compared to $1.94 in the prior year period. Net earnings were $171.8 million compared to $152.8 million in the prior year period. Lower helium sales volumes reduced diluted earnings per share by $0.06 in the current period compared to the prior year period. Additionally, the current quarter’s diluted earnings per share included $0.04 of incremental SAP costs and a year-over-year negative impact of $0.03 due to one less selling day in the current period. Net earnings per diluted share in the prior year period also included net special charges aggregating to $0.08 per diluted share. Net special charges in the current period had no impact on net earnings per diluted share. Net special charges in each period consisted of the following:

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows

Net cash provided by operating activities was $264 million in the current period compared to $201 million in the prior year period.

The following table provides a summary of the major items affecting the Company’s cash flows from operating activities for the periods presented:

____________________

⁽¹⁾ Includes depreciation, amortization, impairment charges, deferred income taxes, gain on sales of plant and equipment and businesses and stock-based compensation expense.

The decrease in the use of cash for working capital in the current period was primarily driven by a significant use of cash in the prior year period for payments related to the unsolicited takeover attempt. Net earnings adjusted for non-cash and non-operating activities provided cash of $329 million in the current period versus $327 million in the prior year period.

As of September 30, 2012, $15 million of the Company’s $48 million cash balance was held by foreign subsidiaries. The Company does not believe it will be necessary to repatriate cash held outside of the U.S. and anticipates its domestic liquidity needs will be met through other funding sources such as cash flows generated from operating activities and external financing arrangements. Accordingly, the Company intends to permanently reinvest the cash in its foreign operations to support working capital needs, investing and financing activities, and future business development. Were the Company’s intention to change, the amounts held within its foreign operations could be repatriated to the U.S., although any repatriations under current U.S. tax laws would be subject to income taxes, net of applicable foreign tax credits.

Capital expenditures as a percent of sales were 6.5% and 7.1% for the six months ended September 30, 2012 and 2011, respectively. Payments for business acquisitions and holdback settlements decreased significantly from the prior year period due to the purchase of two significant businesses, ABCO Gases, Welding and Industrial Supply Company, Inc. and Pain Enterprises, Inc., in the prior year period. During the current period, the Company purchased eight businesses with historical annual revenues of over $19 million. Additionally, during the current period, the Company sold five branch locations in western Canada and received proceeds of $20.2 million related to the sale of these businesses and other plant and equipment.

Free cash flow* in the current period was $121 million, compared to $106 million in the prior year period. The increase in free cash flow from the prior year quarter was driven by adjusted cash from operations*, which was $277 million in the current period compared to $257 million in the prior year period.

Net cash (used in) provided by financing activities	$	(99,253	)	$	31,042

During the current period, net financing activities used cash of $99 million. Net repayments were a use of $69 million, primarily related to a reduction in the funds outstanding under the Company’s commercial paper program. Other financing activities, primarily comprised of proceeds and tax benefits related to the exercise of stock options and stock issued for the employee stock purchase plan, generated cash of $31 million.

In the prior year period, net financing activities provided cash of $31 million. Net borrowings were a source of $359 million, primarily related to the issuance of $250 million of 2.95% senior notes maturing on June 15, 2016. Also during the six months ended September 30, 2011, the Company authorized and completed a share repurchase program purchasing 4.5 million shares of treasury stock for $300 million. Other financing activities, primarily comprised of proceeds and tax benefits related to the exercise of stock options and stock issued for the employee stock purchase plan, generated cash of $19 million.

On October 23, 2012, the Company announced a program to purchase up to $600 million of its outstanding shares of common stock.

* See Non-GAAP reconciliations below.

Dividends

During the six months ended September 30, 2012, the Company paid its stockholders $62 million or $0.40 per share in the first and second quarters of fiscal 2013. During the prior year period, the Company paid dividends of $46 million or $0.32 per share in the second quarter and $0.29 per share in the first quarter of fiscal 2012. Future dividend declarations and associated amounts paid will depend upon the Company’s earnings, financial condition, loan covenants, capital requirements and other factors deemed relevant by management and the Company’s Board of Directors.

Financial Instruments

Money Market Loans

The Company has an agreement with a financial institution to provide access to additional short-term advances not to exceed $35 million. The agreement expires on January 2, 2013, but may be extended subject to renewal provisions contained in the agreement. The advances may be for one to six months with rates at a fixed spread over the corresponding London Interbank Offered Rate (“LIBOR”). At September 30, 2012, there were no advances outstanding under the agreement.

The Company also has an agreement with another financial institution which provides access to short-term advances not to exceed $35 million that expires on July 31, 2013, but may be extended subject to renewal provisions contained in the agreement. The advances are generally overnight or for up to seven days. The amount, term and interest rate of an advance are established through mutual agreement with the financial institution when the Company requests such an advance. At September 30, 2012, there were no advances outstanding under the agreement.

38

Commercial Paper

The Company participates in a $750 million commercial paper program supported by its $750 million revolving credit facility (see below). This program allows the Company to obtain favorable short-term borrowing rates with maturities that may vary, but will generally not exceed 90 days from the date of issue. The Company has used proceeds from the commercial paper program to pay down amounts outstanding under its revolving credit facility and for general corporate purposes. At September 30, 2012, $329 million was outstanding under the commercial paper program and the average effective interest rate on these borrowings was 0.57%.

Trade Receivables Securitization

The Company participates in a securitization agreement with three commercial banks to which it sells qualifying trade receivables on a revolving basis (the “Securitization Agreement”). The Company’s sale of qualified trade receivables is accounted for as a secured borrowing under which qualified trade receivables collateralize amounts borrowed from the commercial banks. Trade receivables that collateralize the Securitization Agreement are held in a bankruptcy-remote special purpose entity, which is consolidated for financial reporting purposes and represents the Company’s only variable interest entity. Qualified trade receivables in the amount of the outstanding borrowing under the Securitization Agreement are not available to the general creditors of the Company. The maximum amount of the Securitization Agreement is $295 million and it bears interest at approximately LIBOR plus 70 basis points. At September 30, 2012, the amount of outstanding borrowing under the Securitization Agreement was $295 million, and it was classified as long-term debt on the Consolidated Balance Sheet. Amounts borrowed under the Securitization Agreement could fluctuate monthly based on the Company’s funding requirements and the level of qualified trade receivables available to collateralize the Securitization Agreement. The Securitization Agreement expires in December 2013 and contains customary events of termination, including standard cross-default provisions with respect to outstanding debt.

Senior Credit Facility

The Company participates in a $750 million Amended and Restated Credit Facility (the “Credit Facility”). The Credit Facility consists of a $650 million U.S. dollar revolving credit line and a $100 million (U.S. dollar equivalent) multi-currency revolving credit line. The maturity date of the Credit Facility is July 19, 2016. Under circumstances described in the Credit Facility, the revolving credit line may be increased by an additional $325 million, provided that the multi-currency revolving credit line may not be increased by more than an additional $50 million.

As of September 30, 2012, the Company had $36 million of borrowings under the Credit Facility, all of which were under the multi-currency revolver. There were no borrowings under the U.S. dollar revolver at September 30, 2012. The Company also had outstanding U.S. letters of credit of $44 million issued under the Credit Facility. U.S. dollar revolver borrowings bear interest at LIBOR plus 125 basis points. The multi-currency revolver bears interest based on a rate of 125 basis points over the Euro currency rate applicable to each foreign currency borrowing. As of September 30, 2012, the average effective interest rate on the multi-currency revolver was 1.67%. In addition to the borrowing spread of 125 basis points for U.S. dollar and multi-currency revolver borrowings, the Company pays a commitment (or unused) fee on the undrawn portion of the Credit Facility equal to 20 basis points per annum.

At September 30, 2012, the financial covenant of the Credit Facility did not restrict the Company’s ability to borrow on the unused portion of the Credit Facility. The Credit Facility contains customary events of default, including, without limitation, failure to make payments, a cross-default to certain other debt, breaches of covenants, breaches of representations and warranties, certain monetary judgments and bankruptcy and ERISA events. In the event of default, repayment of borrowings under the Credit Facility may be accelerated.

The Company also maintains a committed revolving line of credit of up to €8.0 million (U.S. $10.3 million) to fund its operations in France. These revolving credit borrowings are outside of the Company’s Credit Facility. At September 30, 2012, these revolving credit borrowings were €5.1 million (U.S. $6.5 million). The variable interest rates on the French revolving credit borrowings are based on the Euro currency rate plus 125 basis points. As of September 30, 2012, the effective interest rate on the French revolving credit borrowings was 1.32%. This line of credit matures on December 31, 2012.

Total Borrowing Capacity

As of September 30, 2012, $340 million remained unused under the Company’s Credit Facility, after giving effect to the borrowings under the commercial paper program backstopped by the Credit Facility, the outstanding U.S. letters of credit and the borrowings under the multi-currency revolver.

The Company believes that it has sufficient liquidity from cash from operations and under its revolving credit facilities to meet its working capital, capital expenditure and other financial commitments. The financial covenant under the Company’s Credit Facility requires the Company to maintain a leverage ratio not higher than 3.5. The leverage ratio is a contractually

39

defined amount principally reflecting debt and, historically, the amounts outstanding under the Securitization Agreement divided by a contractually defined Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”) for the trailing twelve-month period with pro forma adjustments for acquisitions. The financial covenant calculations of the Credit Facility include the pro forma results of acquired businesses. Therefore, total borrowing capacity is not reduced dollar-for-dollar with acquisition financing. The leverage ratio measures the Company’s ability to meet current and future obligations. At September 30, 2012, the Company’s leverage ratio was 2.4.

The Company continually evaluates alternative financing and believes that it can obtain financing on reasonable terms. The terms of any future financing arrangements depend on market conditions and the Company’s financial position at that time. At September 30, 2012, the Company was in compliance with all covenants under all of its debt agreements.

Senior Notes

At September 30, 2012, the Company had $250 million outstanding of 2.95% senior notes maturing on June 15, 2016 (the “2016 Notes”). The 2016 Notes were issued at a discount with a yield of 2.980%. Interest on the 2016 Notes is payable semi-annually on June 15 and December 15 of each year.

At September 30, 2012, the Company had $300 million outstanding of 2.85% senior notes maturing on October 1, 2013 (the “2013 Notes”). The 2013 Notes were issued at a discount with a yield of 2.871%. Interest on the 2013 Notes is payable semi-annually on April 1 and October 1 of each year.

At September 30, 2012, the Company had $400 million outstanding of 4.5% senior notes maturing on September 15, 2014 (the “2014 Notes”). The 2014 Notes were issued at a discount with a yield of 4.527%. Interest on the 2014 Notes is payable semi-annually on March 15 and September 15 of each year.

At September 30, 2012, the Company had $250 million outstanding of 3.25% senior notes maturing on October 1, 2015 (the “2015 Notes”). The 2015 Notes were issued at a discount with a yield of 3.283%. Interest on the 2015 Notes is payable semi-annually on April 1 and October 1 of each year.

The 2013, 2014, 2015 and 2016 Notes (collectively, the “Senior Notes”) contain covenants that could restrict the incurrence of liens and limit sale and leaseback transactions. Additionally, the Company has the option to redeem the Senior Notes prior to their maturity, in whole or in part, at 100% of the principal plus any accrued but unpaid interest and applicable make-whole payments.

Senior Subordinated Notes

At September 30, 2012, the Company had $215 million outstanding of 7.125% senior subordinated notes maturing on October 1, 2018 (the “2018 Notes”). Interest on the 2018 Notes is payable semi-annually on April 1 and October 1 of each year. The 2018 Notes have a redemption provision which permits the Company, at its option, to call the 2018 Notes at scheduled dates and prices. The first scheduled optional redemption date is October 1, 2013 at a price of 103.563% of the principal amount.

Other Long-term Debt

The Company’s other long-term debt primarily consists of vendor financing of rental welders, capitalized lease obligations and notes issued to sellers of businesses acquired, which are repayable in periodic installments. At September 30, 2012, other long-term debt totaled $3.4 million with an average interest rate of approximately 6% and an average maturity of approximately one year.

Interest Rate Derivatives

In anticipation of the issuance of the 2015 Notes, the Company entered into a treasury rate lock agreement in July 2010 with a notional amount of $100 million that matured in September 2010. The treasury rate lock agreement was designated as a cash flow hedge of the semi-annual interest payments associated with the forecasted issuance of the 2015 Notes. When the treasury rate lock agreement matured, the Company realized a loss of $2.6 million ($1.6 million after tax) which was reported as a component within AOCI and is being reclassified into earnings over the term of the 2015 Notes. For the six months ended September 30, 2012 and 2011, $259 thousand and $259 thousand, respectively, of the loss on the treasury rate lock was reclassified to interest expense. At September 30, 2012, the estimated loss recorded in AOCI on the treasury rate lock agreement that is expected to be reclassified into earnings within the next twelve months is $517 thousand ($326 thousand after tax).

The Company also has variable interest rate swap agreements, which are designated as fair value hedges. For derivative instruments designated as fair value hedges, the gain or loss on the derivative as well as the offsetting gain or loss on the

40

hedged item attributable to the hedged risk are recognized in current earnings.

At September 30, 2012, the Company had five variable interest rate swaps outstanding with a notional amount of $300 million. These variable interest rates swaps effectively convert the Company’s $300 million of fixed rate 2013 Notes to variable rate debt. At September 30, 2012, these swap agreements required the Company to make variable interest payments based on a weighted average forward rate of 1.21% and receive fixed interest payments from the counterparties based on a fixed rate of 2.85%. The maturity of these fair value swaps coincides with the maturity date of the Company’s 2013 Notes in October 2013. During the six months ended September 30, 2012, the fair value of the variable interest rate swaps decreased by $1.8 million to an asset of $4.9 million and was recorded in other non-current assets. The corresponding decrease in the carrying value of the 2013 Notes caused by the hedged risk was $1.8 million and was recorded in long-term debt. The Company records the gain or loss on the hedged item (i.e., the 2013 Notes) and the gain or loss on the variable interest rate swaps in interest expense. The net gain or loss recorded in earnings as a result of hedge ineffectiveness related to the designated fair value hedges was immaterial for the six months ended September 30, 2012 and 2011.

The Company measures the fair value of its interest rate swaps using observable market rates to calculate the forward yield curves used to determine expected cash flows for each interest rate swap agreement. The discounted present values of the expected cash flows are calculated using the same forward yield curve. The discount rate assumed in the fair value calculations is adjusted for non-performance risk, dependent on the classification of the interest rate swap as an asset or liability. If an interest rate swap is a liability, the Company assesses the credit and non-performance risk of Airgas by determining an appropriate credit spread for entities with similar credit characteristics as the Company. If, however, an interest rate swap is in an asset position, a credit analysis of counterparties is performed assessing the credit and non-performance risk based upon the pricing history of counterparty specific credit default swaps or credit spreads for entities with similar credit ratings to the counterparties. The Company does not believe it is at risk for non-performance by its counterparties. However, if an interest rate swap is in an asset position, the failure of one or more of its counterparties would result in an increase in interest expense and a reduction of earnings. The Company compares its fair value calculations to the contract settlement values calculated by the counterparties for each swap agreement for reasonableness.

Interest Expense

A majority of the Company’s variable rate debt is based on a spread over LIBOR. Based on the Company’s fixed to variable interest rate ratio, for every 25 basis point increase in LIBOR, the Company estimates that its annual interest expense would increase by approximately $2.5 million.

obligations and for the execution of its business strategies, including acquisitions, the prepayment of debt, the payment of dividends or to support other investing and financing activities. Non-GAAP measures should be read in conjunction with GAAP financial measures, as non-GAAP measures are merely a supplement to, and not a replacement for, GAAP financial measures. It should be noted as well that the Company’s adjusted cash from operations, adjusted capital expenditures, and free cash flow measures may be different from adjusted cash from operations, adjusted capital expenditures, and free cash flow measures provided by other companies.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Interest Rate Risk

The Company manages its exposure to changes in market interest rates. The interest rate exposure arises primarily from the interest payment terms of the Company’s borrowing agreements. Interest rate derivatives are used to adjust the interest rate risk exposures that are inherent in its portfolio of funding sources. The Company has not established, and will not establish, any interest rate risk positions for purposes other than managing the risk associated with its portfolio of funding sources or anticipated funding sources. The counterparties to interest rate derivatives are major financial institutions. The Company has established counterparty credit guidelines and only enters into transactions with financial institutions with long-term credit ratings of at least a single ‘A’ rating by one of the major credit rating agencies. In addition, the Company monitors its position and the credit ratings of its counterparties, thereby minimizing the risk of non-performance by the counterparties.

The table below summarizes the Company’s market risks associated with debt obligations and interest rate swaps at September 30, 2012. For debt obligations, the table presents cash flows related to payments of principal and interest by fiscal year of maturity. For interest rate swaps, the table presents the notional amounts underlying the agreements by year of maturity. The notional amounts are used to calculate contractual payments to be exchanged and are not actually paid or received. Fair values were computed using market quotes, if available, or were based on discounted cash flows using market interest rates as of the end of the period.

^(a)  The interest rate on the revolving credit facilities is the weighted average of the variable interest rates on the U.S. dollar revolving credit line (which had no borrowings at September 30, 2012) and the multi-currency revolving credit line. The variable interest rates on the U.S. dollar revolving credit line are based on a spread over LIBOR applicable to each tranche under the U.S. credit line. The variable interest rates on the multi-currency revolving credit line are based on a spread over the Euro currency rate applicable to each foreign currency borrowing under the multi-currency credit line.

^(b)  The variable interest rates on the French revolving credit borrowings are based on a spread over the Euro currency rate.

Limitations of the Tabular Presentation

As the table incorporates only those interest rate risk exposures that exist as of September 30, 2012, it does not consider those exposures or positions that could arise after that date. In addition, actual cash flows of financial instruments in future periods may differ materially from prospective cash flows presented in the table due to future fluctuations in variable interest rates, debt levels and the Company’s credit rating.

Foreign Currency Rate Risk

Canadian subsidiaries and the European operations of the Company are funded in part with local currency debt. The Company does not otherwise hedge its exposure to translation gains and losses relating to foreign currency net asset exposures. The Company considers its exposure to foreign currency exchange fluctuations to be immaterial to its financial position and results of operations.

ITEM  4. CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

The Company carried out an evaluation, under the supervision and with the participation of the Company’s Executive Chairman, Chief Executive Officer and Chief Financial Officer, of the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of September 30, 2012. Based on that evaluation, the Company’s Executive Chairman, Chief Executive Officer and Chief Financial Officer have concluded that, as of such date, the Company’s disclosure controls and procedures were effective such that the information

45

required to be disclosed in the Company’s Securities and Exchange Commission (“SEC”) reports (i) is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and (ii) is accumulated and communicated to the Company’s management, including the Company’s Executive Chairman, Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding disclosure.

(b) Changes in Internal Control

There were no changes in internal control over financial reporting that occurred during the quarter ended September 30, 2012 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

The Company has an ongoing initiative to implement a new enterprise information system (the “SAP system”). The SAP system is being implemented in stages, by business unit, through fiscal 2013. Management believes the necessary procedures are in place to maintain effective internal control over financial reporting as the implementation continues.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

The Company is involved in various legal and regulatory proceedings that have arisen in the ordinary course of business and have not been fully adjudicated. These actions, when ultimately concluded and determined, will not, in the opinion of management, have a material adverse effect upon the Company’s consolidated financial condition, results of operations or liquidity.

ITEM  1A. RISK FACTORS.

There have been no material changes from the risk factors previously disclosed in Part I, Item 1A, “Risk Factors,” of the Company's Annual Report on Form 10-K for the year ended March 31, 2012.

Acquisitions and Divestitures

ACQUISITIONS AND DIVESTITURES

Acquisitions

Acquisitions have been recorded using the acquisition method of accounting and accordingly, results of their operations have been included in the Company’s consolidated financial statements since the effective date of each respective acquisition.

During the six months ended September 30, 2012, the Company purchased eight businesses with historical annual sales of approximately $19 million. A total of $18.7 million in cash was paid for the eight businesses and for the settlement of holdback liabilities and payments related to contingent consideration arrangements associated with prior year acquisitions. Transaction and other integration costs incurred during the six months ended September 30, 2012 were $0.7 million and were included in selling, distribution and administrative expenses in the Company’s Consolidated Statement of Earnings. These acquisitions contributed approximately $4 million in net sales for the six months ended September 30, 2012. The acquired businesses complement the Company’s portfolio of products and services while expanding the Company’s geographic coverage.

The Company negotiated the respective purchase prices of the businesses based on the expected cash flows to be derived from their operations after integration into the Company’s existing distribution network and production locations. The acquisition purchase price is allocated based on the fair values of the assets acquired and liabilities assumed, which are based on third-party appraisals and management estimates. Fiscal 2013 purchase price allocations are substantially complete, with the exception of certain tangible assets associated with two acquisitions that were purchased in August 2012 as the Company finalizes appraisals and other analyses. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed related to fiscal 2013 acquisitions, as well as adjustments to finalize the valuations of certain prior year acquisitions.

(In thousands)	Distribution Business Segment			All Other Operations Business Segment			Total
Current assets, net	$	2,887		$	551		$	3,438
Plant and equipment	8,511			1,169			9,680
Goodwill	1,963			2,432			4,395
Other intangible assets	2,948			2,000			4,948
Current liabilities	111			(2,491		)	(2,380		)
Non-current liabilities	(707		)	(722		)	(1,429		)
Total cash consideration	$	15,713		$	2,939		$	18,652

The fair value of trade receivables acquired with the fiscal 2013 acquisitions was $1.8 million, which approximated gross contractual amounts receivable. Goodwill associated with fiscal 2013 acquisitions was $5.7 million and is deductible for income tax purposes. Goodwill largely consists of expected synergies resulting from the acquisitions, including the expansion of geographical coverage that will facilitate the sale of industrial, medical, and specialty gases and related supplies. Intangible assets related to fiscal 2013 acquisitions represent customer relationships and non-competition agreements and amounted to $3.5 million and $2.7 million, respectively. See Note 4 for further information on goodwill and intangible assets.

Pro forma results of operations for these acquisitions have not been presented since the impact is not material to the Company’s Consolidated Statements of Earnings, either individually or in aggregate.

Divestitures

On June 1, 2012, the Company divested the assets and operations of five branch locations in western Canada. The Company realized a gain on the sale of $6.8 million ($5.5 million after tax) recorded in “Other income (expense), net” in its Consolidated Statement of Earnings. The operations were included in the Distribution business segment and contributed net sales that were not material to the Company’s consolidated earnings. Proceeds from the sale were used primarily to pay down outstanding debt under the Company’s multi-currency revolving credit line.

Unsolicited Takeover Attempt, Description [Abstract]

Unsolicited Takeover Attempt

UNSOLICITED TAKEOVER ATTEMPT

On February 11, 2010, Air Products and Chemicals, Inc.'s (“Air Products”) initiated an unsolicited tender offer for all of the Company’s outstanding shares of common stock. In connection with this unsolicited tender offer, Air Products filed an action against the Company and members of its Board in the Delaware Court of Chancery. On February 15, 2011, the Delaware Court of Chancery denied in their entirety all requests for relief by Air Products and dismissed with prejudice all claims asserted against the Company and its directors. Air Products promptly terminated its unsolicited tender offer and no appeal of the Court’s decision was filed. In connection with the unsolicited tender offer and related litigation, the Company incurred on a cumulative basis a net $60.0 million of legal and professional fees and other costs. During the three months ended June 30, 2011, the Company recognized benefits of $6.7 million from lower than previously estimated net costs related to the unsolicited takeover attempt.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

BASIS OF PRESENTATION

The consolidated financial statements include the accounts of Airgas, Inc. and its subsidiaries (“Airgas” or the “Company”). Intercompany accounts and transactions are eliminated in consolidation. The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). These consolidated financial statements do not include all disclosures required for annual financial statements. These consolidated financial statements should be read in conjunction with the complete disclosures contained in the Company’s audited consolidated financial statements for the fiscal year ended March 31, 2012.

The preparation of financial statements in accordance with GAAP requires the use of estimates. The consolidated financial statements reflect, in the opinion of management, reasonable estimates and all adjustments necessary to present fairly the Company’s results of operations, financial position and cash flows for the periods presented. The interim operating results are not necessarily indicative of the results to be expected for the entire year.

Effective January 1, 2012, the Company changed its method of accounting for the portion of its hardgoods inventory valued using the last-in, first-out (“LIFO”) method to the average-cost method. The Company applied this change in accounting principle through retrospective application to the prior year’s consolidated financial statements. The impact of the change was immaterial.

Earnings Per Share [Abstract]

Earnings Per Share

EARNINGS PER SHARE

Basic earnings per share is calculated by dividing net earnings by the weighted average number of shares of the Company’s common stock outstanding during the period. Outstanding shares consist of issued shares less treasury stock. Diluted earnings per share is calculated by dividing net earnings by the weighted average common shares outstanding adjusted for the dilutive effect of common stock equivalents related to stock options and the Company’s ESPP.

Outstanding stock options that are anti-dilutive are excluded from the Company’s diluted earnings per share computation. There were approximately 1.9 million and 2.0 million shares covered by outstanding stock options that were not dilutive for the three months ended September 30, 2012 and 2011, respectively. There were approximately 1.4 million and 1.7 million shares covered by outstanding stock options that were not dilutive for the six months ended September 30, 2012 and 2011, respectively.

The table below presents the computation of basic and diluted weighted average common shares outstanding for the three and six months ended September 30, 2012 and 2011:

Money Market Loans

The Company has an agreement with a financial institution to provide access to additional short-term advances not to exceed $35 million. The agreement expires on January 2, 2013, but may be extended subject to renewal provisions contained in the agreement. The advances may be for one to six months with rates at a fixed spread over the corresponding London Interbank Offering Rate (“LIBOR”). At September 30, 2012, there were no advances outstanding under the agreement.

The Company also has an agreement with another financial institution which provides access to short-term advances not to exceed $35 million that expires on July 31, 2013, but may be extended subject to renewal provisions contained in the agreement. The advances are generally overnight or for up to seven days. The amount, term and interest rate of an advance are established through mutual agreement with the financial institution when the Company requests such an advance. At September 30, 2012, there were no advances outstanding under the agreement.

Commercial Paper

The Company participates in a $750 million commercial paper program supported by its $750 million revolving credit facility (see below). This program allows the Company to obtain favorable short-term borrowing rates with maturities that may vary, but will generally not exceed 90 days from the date of issue. The Company has used proceeds from the commercial paper program to pay down amounts outstanding under its revolving credit facility and for general corporate purposes. At September 30, 2012, $329 million was outstanding under the commercial paper program and the average effective interest rate on these borrowings was 0.57%.

Trade Receivables Securitization

The Company participates in a securitization agreement with three commercial banks to which it sells qualifying trade receivables on a revolving basis (the “Securitization Agreement”). The Company’s sale of qualified trade receivables is accounted for as a secured borrowing under which qualified trade receivables collateralize amounts borrowed from the commercial banks. Trade receivables that collateralize the Securitization Agreement are held in a bankruptcy-remote special purpose entity, which is consolidated for financial reporting purposes and represents the Company’s only variable interest entity. Qualified trade receivables in the amount of the outstanding borrowing under the Securitization Agreement are not available to the general creditors of the Company. The maximum amount of the Securitization Agreement is $295 million and it bears interest at approximately LIBOR plus 70 basis points. At September 30, 2012, the amount of outstanding borrowing under the Securitization Agreement was $295 million, and it was classified as long-term debt on the Consolidated Balance Sheet. Amounts borrowed under the Securitization Agreement could fluctuate monthly based on the Company’s funding requirements and the level of qualified trade receivables available to collateralize the Securitization Agreement. The Securitization Agreement expires in December 2013 and contains customary events of termination, including standard cross-default provisions with respect to outstanding debt.

Senior Credit Facility

The Company participates in a $750 million Amended and Restated Credit Facility (the “Credit Facility”). The Credit Facility consists of a $650 million U.S. dollar revolving credit line and a $100 million (U.S. dollar equivalent) multi-currency revolving credit line. The maturity date of the Credit Facility is July 19, 2016. Under circumstances described in the Credit Facility, the revolving credit line may be increased by an additional $325 million, provided that the multi-currency revolving credit line may not be increased by more than an additional $50 million.

As of September 30, 2012, the Company had $36 million of borrowings under the Credit Facility, all of which were under the multi-currency revolver. There were no borrowings under the U.S. dollar revolver at September 30, 2012. The Company also had outstanding U.S. letters of credit of $44 million issued under the Credit Facility. U.S. dollar revolver borrowings bear interest at LIBOR plus 125 basis points. The multi-currency revolver bears interest based on a rate of 125 basis points over the Euro currency rate applicable to each foreign currency borrowing. As of September 30, 2012, the average effective interest rate on the multi-currency revolver was 1.67%. In addition to the borrowing spread of 125 basis points for U.S. dollar and multi-currency revolver borrowings, the Company pays a commitment (or unused) fee on the undrawn portion of the Credit Facility equal to 20 basis points per annum.

At September 30, 2012, the financial covenant of the Credit Facility did not restrict the Company’s ability to borrow on the unused portion of the Credit Facility. The Credit Facility contains customary events of default, including, without limitation, failure to make payments, a cross-default to certain other debt, breaches of covenants, breaches of representations and warranties, certain monetary judgments and bankruptcy and ERISA events. In the event of default, repayment of borrowings under the Credit Facility may be accelerated. As of September 30, 2012, $340 million remained available under the Company’s Credit Facility, after giving effect to the borrowings under the commercial paper program backstopped by the Credit Facility, the outstanding U.S. letters of credit and the borrowings under the multi-currency revolver.

The Company also maintains a committed revolving line of credit of up to €8.0 million (U.S. $10.3 million) to fund its operations in France. These revolving credit borrowings are outside of the Company’s Credit Facility. At September 30, 2012, these revolving credit borrowings were €5.1 million (U.S. $6.5 million). The variable interest rates on the French revolving credit borrowings are based on the Euro currency rate plus 125 basis points. As of September 30, 2012, the effective interest rate on the French revolving credit borrowings was 1.32%. This line of credit matures on December 31, 2012.

Senior Notes

At September 30, 2012, the Company had $300 million outstanding of 2.85% senior notes maturing on October 1, 2013 (the “2013 Notes”). The 2013 Notes were issued at a discount with a yield of 2.871%. Interest on the 2013 Notes is payable semi-annually on April 1 and October 1 of each year.

Summary by Business Segment

SUMMARY BY BUSINESS SEGMENT

Business segment information for the Company’s Distribution and All Other Operations business segments is presented below for the three and six months ended September 30, 2012 and 2011. Business segment operating results for the prior periods were adjusted for the retrospective application of the LIFO-to-average-cost change in accounting principle implemented during the year ended March 31, 2012. Although corporate operating expenses are generally allocated to each business segment based on sales dollars, the Company reports expenses (excluding depreciation) related to the implementation of its SAP system and the Company’s withdrawal from various multi-employer pension plans (“MEPPs”) under selling, distribution and administrative expenses in the “Eliminations and Other” column below. Additionally, the Company’s restructuring and other special charges and the legal, professional and other costs (benefits) incurred as a result of the Air Products & Chemicals, Inc. (“Air Products”) unsolicited takeover attempt are not allocated to the Company’s business segments. These costs (benefits) are also reflected in the “Eliminations and Other” column below. Corporate assets have been allocated to the Distribution business segment, intercompany sales are recorded on the same basis as sales to third parties, and intercompany transactions are eliminated in consolidation. Management utilizes more than one measurement and multiple views of data to measure segment performance and to allocate resources to the segments. However, the predominant measurements are consistent with the Company’s consolidated financial statements and accordingly, are reported on the same basis below.

Derivative Instruments And Hedging Activities

General Discussion of Derivative Instruments and Hedging Activities [Abstract]

Derivative Instruments And Hedging Activities

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

The Company manages its exposure to changes in market interest rates. The Company’s involvement with derivative instruments is limited to highly effective interest rate swap agreements used to manage well-defined interest rate risk exposures and treasury rate lock agreements used to fix the interest rate related to forecasted debt issuances. The Company monitors its positions and credit ratings of its counterparties and does not anticipate non-performance by the counterparties. Interest rate swap and treasury rate lock agreements are not entered into for trading purposes. The Company recognizes derivative instruments as either assets or liabilities at fair value on the Consolidated Balance Sheets. At September 30, 2012, the Company was party to a total of five interest rate swap agreements with an aggregate notional amount of $300 million.

Cash Flow Hedges

In anticipation of the issuance of the 2015 Notes, the Company entered into a treasury rate lock agreement in July 2010 with a notional amount of $100 million that matured in September 2010. The treasury rate lock agreement was designated as a cash flow hedge of the semi-annual interest payments associated with the forecasted issuance of the 2015 Notes. When the treasury rate lock agreement matured, the Company realized a loss of $2.6 million ($1.6 million after tax) which was reported as a component within Accumulated Other Comprehensive Income (“AOCI”) and is being reclassified into earnings over the term of the 2015 Notes. For the six months endedSeptember 30, 2012 and 2011, $259 thousand of the loss on the treasury rate lock was reclassified to interest expense. At September 30, 2012, the estimated loss recorded in AOCI on the treasury rate lock agreement that is expected to be reclassified into earnings within the next twelve months is $517 thousand ($326 thousand after tax).

Fair Value Hedges

The Company also has variable interest rate swap agreements, which are designated as fair value hedges. For derivative instruments designated as fair value hedges, the gain or loss on the derivative as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in current earnings.

At September 30, 2012, the Company had five variable interest rate swaps outstanding with a notional amount of $300 million. These variable interest rates swaps effectively convert the Company’s $300 million of fixed rate 2013 Notes to variable rate debt. At September 30, 2012, these swap agreements required the Company to make variable interest payments based on a weighted average forward rate of 1.21% and receive fixed interest payments from the counterparties based on a fixed rate of 2.85%. The maturity of these fair value swaps coincides with the maturity date of the Company’s 2013 Notes in October 2013. During the six months ended September 30, 2012, the fair value of the variable interest rate swaps decreased by $1.8 million to an asset of $4.9 million and was recorded in other non-current assets. The corresponding decrease in the carrying value of the 2013 Notes caused by the hedged risk was $1.8 million and was recorded in long-term debt. The Company records the gain or loss on the hedged item (i.e., the 2013 Notes) and the gain or loss on the variable interest rate swaps in interest expense. The net gain or loss recorded in earnings as a result of hedge ineffectiveness related to the designated fair value hedges was immaterial for the three and six months ended September 30, 2012 and 2011.

Tabular Disclosure

The following tables reflect the fair values of derivative instruments on the Company’s Consolidated Balance Sheets as well as the effect of derivative instruments on the Company’s earnings and stockholders’ equity.

Fair Value Of Financial Assets And Liabilities

Fair Value Disclosures [Abstract]

Fair Value Of Financial Assets And Liabilities

FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities recorded at fair value are classified based upon the level of judgment associated with the inputs used to measure their fair value. The hierarchical levels related to the subjectivity of the valuation inputs are defined as follows:

• Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities at the measurement date.

• Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable, either directly or indirectly, through corroboration with observable market data at the measurement date.

• Level 3 inputs are unobservable inputs that reflect management’s best estimate of the assumptions (including assumptions about risk) that market participants would use in pricing the asset or liability at the measurement date.

The carrying value of cash, trade receivables, other current receivables, trade payables and other current liabilities (e.g., deposit liabilities, cash overdrafts, etc.) approximates fair value.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Assets and liabilities measured at fair value on a recurring basis at September 30, 2012 and March 31, 2012 are categorized in the tables below based on the lowest level of significant input to the valuation. During the periods presented, there were no transfers between fair value hierarchical levels.

Total liabilities measured at fair value on a recurring basis	$	13,638	$	11,126	$	—	$	2,512

The following is a general description of the valuation methodologies used for financial assets and liabilities measured at fair value:

Deferred compensation plan assets and corresponding liabilities — The Company’s deferred compensation plan assets consist of open-ended mutual funds (Level 1) and are included within other non-current assets on the Consolidated Balance Sheets. The Company’s deferred compensation plan liabilities are equal to the plan’s assets and are included within other non-current liabilities on the Consolidated Balance Sheets. Gains or losses on the deferred compensation plan assets are recognized as other income (expense), net, while gains or losses on the deferred compensation plan liabilities are recognized as compensation expense in the Consolidated Statements of Earnings.

Derivative assets — interest rate swap agreements — The Company’s variable interest rate swap agreements are with highly rated counterparties, are designated as fair value hedges and effectively convert the Company’s fixed rate 2013 Notes to variable rate debt. The swap agreements are valued using an income approach that relies on observable market inputs such as interest rate yield curves and treasury spreads (Level 2). Expected future cash flows are converted to a present value amount based upon market expectations of the changes in these interest rate yield curves. The fair values of the Company’s interest rate swap agreements are included within other non-current assets on the Consolidated Balance Sheets. See Note 7 for additional derivatives disclosures.

Contingent consideration liability — As part of the consideration for a fiscal 2011 acquisition, the Company has an arrangement in place whereby future consideration in the form of cash may be transferred to the seller contingent upon the achievement of certain earnings targets. The fair value of the contingent consideration arrangement was estimated using the income approach with inputs that are not observable in the market. Key assumptions include a discount rate commensurate with the level of risk of achievement, time horizon and other risk factors, and probability adjusted earnings growth, all of which the Company believes are appropriate and representative of market participant assumptions. Of the total liability for the contingent consideration arrangement at September 30, 2012, $1.7 million is included within other non-current liabilities while the remainder is included within accrued expenses and other current liabilities on the Consolidated Balance Sheet. The impact on the Company's earnings as a result of the contingent consideration arrangement for the three and six months ended September 30, 2012 was immaterial.

Changes in the fair value of recurring fair value measurements using significant unobservable inputs (Level 3) for the six months ended September 30, 2012 were as follows (in thousands):

Balance at March 31, 2012	$	2,512
Contingent consideration liability recorded	—
Settlements made during the period	(140		)
Adjustments to fair value measurement	122
Balance at September 30, 2012	$	2,494

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Certain assets and liabilities are measured at fair value on a nonrecurring basis in periods subsequent to initial recognition. Assets measured at fair value on a nonrecurring basis during the six months ended September 30, 2012 and 2011 are categorized in the table below based on the lowest level of significant input to the valuation, and are based on amounts as measured at the time of adjustment. There were no liabilities measured at fair value on a nonrecurring basis during the six months ended September 30, 2012 or 2011.

In June 2012, the Company re-evaluated the economic viability of a small hospital piping construction business. As a result of an impairment analysis performed on the assets at this reporting unit, the Company recorded a charge of $1.7 million related to certain of the intangible assets associated with this business for the six months ended September 30, 2012, which was reflected in the “Restructuring and other special charges” line item of the Company’s Consolidated Statement of Earnings for the six months ended September 30, 2012. The Company used a variation of the income approach, namely the excess earnings method, to estimate the fair value of the intangible assets associated with the business. Under this approach, an intangible asset’s fair value is estimated to be the present value of the incremental after-tax cash flows attributable solely to the intangible asset over its remaining useful life. Key inputs in this model include the cash flow forecast, discount rate, contributory asset charges and tax amortization benefits. As of the evaluation date, the remeasured other intangible assets related to this reporting unit totaled $0.5 million.

In September 2011, the Company performed an evaluation of the recoverability of the fixed assets related to one of its liquid carbon dioxide (“CO₂”) plants. This evaluation was based upon the receipt of notice that a supplier’s hydrogen plant, which generates carbon dioxide as a by-product that serves as the feedstock for the Company's co-located liquid carbon dioxide plant, will cease operations in calendar year 2013. As a result of the analysis, the Company remeasured the fixed assets of its liquid carbon dioxide plant and recognized an impairment charge of $2.5 million which was reflected in the “Restructuring and other special charges” line item of the Company’s Consolidated Statement of Earnings for the three and six months ended September 30, 2011. The remeasured plant fixed assets totaled $8.8 million at the date of evaluation and were included within plant and equipment on the Company’s Consolidated Balance Sheet. The Company used an income approach to estimate the fair value of the plant assets based on significant unobservable inputs (Level 3). Factors such as expected future revenues and margins, the likelihood of asset redeployment and the length of the remaining operating term were considered in determining the future cash flows of the plant assets.

The assets and asset groups described above will not be remeasured at fair value on a recurring basis; however, they are still subject to fair value measurements to test for recoverability of the carrying amounts should future conditions warrant an evaluation.

Fair Value of Debt

The carrying value of debt, which is reported on the Company’s Consolidated Balance Sheets, generally reflects the cash proceeds received upon its issuance, net of subsequent repayments, plus the impact of the Company’s fair value hedges. The fair value of the Company’s variable interest rate revolving credit borrowings disclosed in the table below was estimated based on observable forward yield curves and credit spreads management believes a market participant would assume for these facilities under market conditions as of the balance sheet date (Level 2). The fair values of the fixed rate notes disclosed below were determined based on quoted prices from the broker/dealer market, observable market inputs for similarly termed treasury notes adjusted for the Company’s credit spread and inputs management believes a market participant would use in determining imputed interest for obligations without a stated interest rate (Level 2). The fair values of the securitized receivables and the commercial paper approximate their carrying values.

Restructuring Costs

In May 2011, the Company announced the alignment of its twelve regional distribution companies into four new divisions, and the consolidation of its regional company accounting and certain administrative functions into four newly created Business Support Centers (“BSCs”). Additionally, the Company initiated a related change in its legal entity structure on January 1, 2012 whereby the majority of Airgas’ distribution businesses have merged or will merge into a single limited liability company (“LLC”) of which the Company is the sole member. Each of the Company’s twelve regional distribution companies operated (prior to conversion to SAP) or operates its own accounting and administrative functions. Enabled by the Company’s conversion to a single information platform across all of its regional companies as part of the SAP implementation, the restructuring will allow Airgas to more effectively utilize its resources across regional company boundaries and to form an operating structure that will help Airgas leverage the full benefits of its new SAP platform.

During the three and six months ended September 30, 2012, the Company recorded $0.3 million and $0.8 million, respectively, in restructuring costs. During the prior year period, the Company recorded $13.3 million in restructuring costs related to severance benefits to be paid out through fiscal 2014, all of which were recorded in the three months ended June 30, 2011.

The activity in the accrued liability balances associated with the restructuring plan was as follows for the six months ended September 30, 2012:

(In thousands)	Severance Costs			Facility Exit and Other Costs			Total
Balance at March 31, 2012	$	13,138		$	990		$	14,128

Balance at September 30, 2012	$	11,434		$	485		$	11,919

Of the $11.9 million in accrued restructuring costs at September 30, 2012, $10.9 million was included in accrued expenses and other current liabilities and $1.0 million was included in other non-current liabilities on the Company’s Consolidated Balance Sheet. The restructuring costs were not allocated to the Company’s business segments (see Note 13).

Other Related Costs

For the three and six months ended September 30, 2012, the Company also incurred $2.1 million and $5.6 million, respectively, of other costs related to the divisional realignment and LLC restructuring. These costs primarily related to transition staffing for the BSCs, legal costs and other expenses associated with the Company’s organizational and legal entity changes.

The realignment is expected to be completed by the end of fiscal 2013. The Company expects to incur additional restructuring and other related costs, primarily related to transition staffing, legal and relocation costs, of approximately $5 million for the remainder of the fiscal year.

Asset Impairment Charges

The Company recorded special charges of $1.7 million and $2.5 million related to asset impairments during the six months ended September 30, 2012 and 2011, respectively – see Notes 4 and 8 for further information.

Goodwill And Other Intangible Assets

GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill

Goodwill represents the excess of the purchase price of an acquired entity over the amounts assigned to the assets acquired and liabilities assumed in a business combination. The valuations of assets acquired and liabilities assumed from certain recent acquisitions are based on preliminary estimates of fair value and are subject to revision as the Company finalizes appraisals and other analyses. Changes in the carrying amount of goodwill by business segment for the six months ended September 30, 2012 were as follows:

(In thousands)	Distribution Business Segment			All Other Operations Business Segment		Total
Balance at March 31, 2012	$	969,394		$	194,409	$	1,163,803

Other intangible assets primarily consist of customer relationships, which are amortized over the estimated benefit periods which range from seven to 17 years, and non-competition agreements, which are amortized over the terms of the agreements. The determination of the estimated benefit periods associated with customer relationships is based on an analysis of historical customer sales attrition information and other customer-related factors at the date of acquisition. There are no expected residual values related to these intangible assets. The Company evaluates the estimated benefit periods and recoverability of its intangible assets when facts and circumstances indicate that the lives may not be appropriate and/or the carrying values of the assets may not be recoverable. If the carrying value is not recoverable, impairment is measured as the amount by which the carrying value exceeds its estimated fair value. Fair value is generally estimated based on appraised value or other techniques. Estimated future amortization expense by fiscal year is as follows: remainder of fiscal 2013 - $12.4 million; 2014 - $23.2 million; 2015 - $21.6 million; 2016 - $20.1 million; 2017 - $18.2 million; and $109.0 million thereafter.

Impairment Evaluation

In June 2012, the Company re-evaluated the economic viability of a small hospital piping construction business associated with a reporting unit in the Company’s All Other Operations business segment. In accordance with relevant accounting guidance, if events or circumstances exist indicating that it is more likely than not that goodwill may be impaired, the Company is required to perform an interim assessment of the carrying value of goodwill. However, prior to performing the test for goodwill impairment, the Company is required to perform an assessment of the recoverability of the long-lived assets (including amortizing intangible assets) of the business. Long-lived assets are not considered recoverable when the carrying amount of the long-lived asset or asset group exceeds the undiscounted expected future cash flows. If long-lived assets are not recoverable, an impairment loss is recognized to the extent that the carrying amount exceeds fair value.

As a result of the impairment analysis performed on the long-lived assets at this reporting unit, the Company recorded a charge of $1.7 million related to certain of the intangible assets associated with this business during the three months ended June 30, 2012. The charge was reflected in the “Restructuring and other special charges” line item of the Company’s Consolidated Statement of Earnings and was not allocated to the Company’s business segments (see Note 13).

Subsequent to the intangible asset write-down, the Company performed an assessment of the carrying value of goodwill associated with the reporting unit. The assessment did not indicate that the reporting unit’s goodwill was potentially impaired. However, the fair value of the reporting unit was not substantially in excess of its carrying amount, consistent with the Company’s most recent annual goodwill impairment test. The Company will continue to monitor this business and consider additional interim analyses of goodwill as appropriate; however, the amount of goodwill associated with this reporting unit is not material to the Company’s consolidated financial statements. The Company performs its annual impairment assessment of the carrying value of goodwill associated with each of its reporting units as of October 31 of each year.
