Major Accounting Policies	Jun. 30, 2015
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Major Accounting Policies	1. BASIS OF PRESENTATION AND MAJOR ACCOUNTING POLICIES Refer to our 2014 Form 10-K for a description of major accounting policies. There have been no significant changes to these accounting policies during the first nine months of fiscal year 2015. The Company realigned its businesses in new reporting segments and began operating under the new structure effective 1 October 2014. Prior year segment information presented has been restated to conform with the fiscal year 2015 presentation. See Note 19, Business Segment Information, for further details. The consolidated financial statements of Air Products and Chemicals, Inc. and its subsidiaries (“we,” “our,” “us,” the “Company,” “Air Products,” or “registrant”) included herein have been prepared by us, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. In our opinion, the accompanying statements reflect adjustments necessary to present fairly the financial position, results of operations, and cash flows for those periods indicated, and contain adequate disclosure to make the information presented not misleading. Adjustments included herein are of a normal, recurring nature unless otherwise disclosed in the Notes. The interim results for the periods indicated herein, however, do not reflect certain adjustments, such as the valuation of inventories on the last-in, first-out (LIFO) cost basis, which are only finally determined on an annual basis. The consolidated financial statements and related Notes included herein should be read in conjunction with the financial statements and Notes thereto included in our latest Form 10-K in order to fully understand the basis of presentation. Results of operations for interim periods are not necessarily indicative of the results of operations for a full year.

New Accounting Guidance	9 Months Ended
New Accounting Guidance	Jun. 30, 2015
New Accounting Guidance [Abstract]
New Accounting Guidance	2. NEW ACCOUNTING GUIDANCE Accounting Guidance Implemented in 2015 Unrecognized Tax Benefits In July 2013, the Financial Accounting Standards Board (FASB) issued guidance to require standard presentation of an unrecognized tax benefit when a carryforward related to net operating losses or tax credits exists. We adopted this guidance prospectively beginning in the first quarter of fiscal year 2015. This guidance did not have a significant impact on our consolidated financial statements. New Accounting Guidance to be Implemented Discontinued Operations In April 2014, the FASB issued an update to change the criteria for determining which disposals qualify as a discontinued operation and to expand related disclosure requirements. Under the new guidance, a disposal is required to be reported in discontinued operations if the disposal represents a strategic shift that has or will have a major effect on operations and financial results. This guidance will be effective prospectively for new disposals and new disposal groups classified as held for sale beginning in fiscal year 2016, with early adoption permitted. Revenue Recognition In May 2014, the FASB issued guidance based on the principle that revenue is recognized in an amount expected to be collected and to which the entity expects to be entitled in exchange for the transfer of goods or services. As currently issued, this guidance is effective for us beginning in fiscal year 2018 and can be adopted either retrospectively or as a cumulative-effect adjustment as of the date of adoption. In July 2015, the FASB approved a one-year deferral of the effective date as well as providing the option to early adopt the standard on the original effective date. Accordingly, we would have the option to adopt the standard in either fiscal year 2018 or 2019. We are currently evaluating the adoption alternatives and impact that this update will have on our consolidated financial statements. Share-Based Compensation In June 2014, the FASB issued guidance clarifying that share-based compensation performance targets that could be achieved after the requisite service period should be treated as a performance condition that affects vesting, rather than a condition that affects the grant-date fair value of the award. This guidance is effective for us beginning in fiscal year 2017, with early adoption permitted. We do not expect this guidance to have a significant impact on our consolidated financial statements. Consolidation Analysis In February 2015, the FASB issued an update to amend current consolidation guidance. The guidance impacts the analysis an entity must perform in determining if it should consolidate certain legal entities such as limited partnerships, limited liability corporations, and securitization structures. The guidance is effective beginning fiscal year 2017, with early adoption permitted. The guidance may be applied retrospectively or using a modified retrospective approach, by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption. We are currently evaluating the impact this update will have on our consolidated financial statements. Debt Issuance Costs In April 2015, the FASB issued guidance requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the debt instead of as a separate deferred asset. This change in accounting principle will be effective beginning in fiscal year 2017 with early adoption permitted and must be applied retrospectively. This guidance only affects the presentation of debt issuance costs and will not have a significant impact on our consolidated financial statements. Defined Benefit Measurement Date In April 2015, the FASB issued an update to provide a practical expedient on the measurement date of defined benefit plan assets and obligations including interim remeasurements related to significant events. The guidance is effective prospectively beginning in fiscal year 2017, with early adoption permitted. The guidance will not have a significant impact on our consolidated financial statements.

Discontinued Operations	Jun. 30, 2015
Discontinued Operations [Abstract]
Discontinued Operations	3. DISCONTINUED OPERATIONS During the second quarter of 2012, the Board of Directors authorized the sale of our Homecare business which has been accounted for as a discontinued operation. In the third quarter of 2012, we sold the majority of our Homecare business to The Linde Group for sale proceeds of €590 million ($777) and recognized a gain of $207.4 ($150.3 after-tax, or $.70 per share). Additionally, during the third quarter of 2012, an impairment charge of $33.5 ($29.5 after-tax, or $.14 per share) was recorded to write down the remaining business, which was primarily in the United Kingdom and Ireland, to its estimated net realizable value. In the fourth quarter of 2013, an additional charge of $18.7 ($13.6 after-tax, or $.06 per share) was recorded to update our estimate of the net realizable value. In the first quarter of 2014, we sold the remaining portion of the Homecare business for £6.1 million ($9.8) and recorded a gain on sale of $2.4. We entered into an operations guarantee related to the obligations under certain homecare contracts assigned in connection with the transaction. Our maximum potential payment under the guarantee is £20 million (approximately $31 at 30 June 2015), and our exposure will be extinguished by 2020. The fair value of the guarantee is not material.

Refer to Note 19, Business Segment Information, for additional details. As a result of this reorganization, we will incur ongoing severance and other charges.

For the three and nine months ended 30 June 2015, we recognized an expense of $58.2 ($38.8 after-tax, or $.18 per share) and $146.0 ($98.7 after-tax, or $.45 per share), respectively. Severance and other benefits totaled $22.5 and $110.3 for the three and nine months ended 30 June 2015, respectively. During the first nine months of fiscal year 2015, the reorganization has resulted in the elimination of approximately 1,500 positions. The third quarter expense also included $35.7 for asset and associated contract actions related to the exit of product lines within the Industrial Gases – Global and Materials Technologies segments. The 2015 charges related to the segments as follows: $19.9 in Industrial Gases – Americas, $40.0 in Industrial Gases – EMEA, $8.1 in Industrial Gases – Asia, $31.4 in Industrial Gases – Global, $19.3 in Materials Technologies, and $27.3 in Corporate and other.

During the fourth quarter of 2014, an expense of $12.7 ($8.2 after-tax, or $.04 per share) was incurred relating to the elimination of approximately 50 positions. The 2014 charge related to the segments as follows: $2.9 in Industrial Gases – Americas, $3.1 in Industrial Gases – EMEA, $1.5 in Industrial Gases – Asia, $1.5 in Industrial Gases – Global, $1.6 in Materials Technologies, and $2.1 in Corporate and other.

The following table summarizes the carrying amount of the accrual for the business realignment and reorganization at

2013 Plan

During the fourth quarter of 2013, we recorded an expense of $231.6 ($157.9 after-tax, or $.74 per share) reflecting actions to better align our cost structure with current market conditions. The asset and contract actions primarily impacted the Electronics Materials business due to continued weakness in the photovoltaic (PV) and light-emitting diode (LED) markets. The severance and other contractual benefits primarily impacted our Industrial Gases businesses and corporate functions in response to weaker than expected business conditions in Europe and Asia, reorganization of our operations and functional areas, and previously announced senior executive changes.

Business Combinations
Business Combinations	5. BUSINESS COMBINATIONS On 30 December 2014, we acquired our partner’s equity ownership interest in a liquefied industrial gases production joint venture in North America for $22.6, which increased our ownership from 50% to 100%. The transaction was accounted for as a business combination, and subsequent to the acquisition, the results are consolidated within our Industrial Gases – Americas segment. The assets acquired, primarily plant and equipment, were recorded at their fair market values as of the acquisition date. The acquisition date fair value of the previously held equity interest was determined using a discounted cash flow analysis under the income approach. The nine months ended 30 June 2015 include a gain of $17.9 ($11.2 after-tax, or $.05 per share) as a result of revaluing our previously held equity interest to fair value as of the acquisition date. This gain is reflected on the consolidated income statements as “Gain on previously held equity interest.”

EQUITY AFFILIATES In 2012, we entered into an agreement with ACWA Holding to pursue industrial gas supply projects in Saudi Arabia. On 19 April 2015, a joint venture between Air Products and ACWA Holding entered into a 20-year oxygen and nitrogen supply agreement to supply Saudi Aramco’s oil refinery and power plant being built in Jazan, Saudi Arabia. Air Products will own 25% of the joint venture, invest approximately $100, and guarantee the repayment of its share of an equity bridge loan. ACWA also guarantees their share of the loan. Air Products has also entered into a sale of equipment contract with the joint venture to engineer, procure, and construct the industrial gas facilities that will supply the gases to Saudi Aramco. We provided bank guarantees to the joint venture to support our performance under the contract. For further details on the guarantees, see Note 12, Commitments and Contingencies. We determined that the joint venture is a variable interest entity, for which we are not the primary beneficiary. There have been no other significant changes to our investments in equity affiliates during fiscal year 2015.

Accumulated impairment losses^(A)		(266.2)		(284.8)

^(A)Amount is attributable to the Industrial Gases – Americas segment and includes currency translation of $39.0 and $20.4 as of 30 June 2015
and 30 September 2014, respectively.

Due to the reorganization of our business effective as of 1 October 2014, we conducted a goodwill impairment test in the first quarter of 2015 on our thirteen reporting units. We determined that the fair value of all of our reporting units, except Latin America within the Industrial Gases – Americas segment, substantially exceeded their carrying value. The Latin America reporting unit is composed predominately of our Indura business acquired by the Company in 2012, with business units in Chile, Colombia, and other Latin America countries. In the fourth quarter of 2014, we recorded an impairment of goodwill of $305.2 related to this reporting unit. As of 1 October 2014, the fair value of our Latin America reporting unit exceeded its carrying value by approximately 10% primarily due to depreciation, amortization, and the impact of a Chilean tax rate change which had previously been reflected in the determination of the fair value of the reporting unit but not reflected in the carrying value until the enactment date. The fair value of the Latin America reporting unit at 1 October 2014 was estimated based on a similar outlook and assumptions as those used in the 2014 impairment testing. As of 30 June 2015, the carrying value of Latin America goodwill was $218.3, or approximately 1.2% of consolidated total assets.

Management judgment is required in the determination of each assumption utilized in the valuation model, and actual results could differ from the estimates. Revenue growth and EBITDA margin assumptions are two primary drivers of the fair value of our Latin America reporting unit, and these assumptions are underpinned by our expectations for long-term manufacturing growth in the region. We will continue to evaluate goodwill on an annual basis as of the beginning of our fourth fiscal quarter and whenever there are indicators of potential impairment.

9. FINANCIAL INSTRUMENTS

Currency Price Risk Management

Our earnings, cash flows, and financial position are exposed to foreign currency risk from foreign currency-denominated transactions and net investments in foreign operations. It is our policy to minimize our cash flow volatility from changes in currency exchange rates. This is accomplished by identifying and evaluating the risk that our cash flows will change in value due to changes in exchange rates and by executing the appropriate strategies necessary to manage such exposures. Our objective is to maintain economically balanced currency risk management strategies that provide adequate downside protection.

Forward Exchange Contracts

We enter into forward exchange contracts to reduce the cash flow exposure to foreign currency fluctuations associated with highly anticipated cash flows and certain firm commitments, such as the purchase of plant and equipment. We also enter into forward exchange contracts to hedge the cash flow exposure on intercompany loans. The portfolio of forward exchange contracts consists primarily of Euros and U.S. dollars as well as Euros and British Pound Sterling. The maximum remaining term of any forward exchange contract currently outstanding and designated as a cash flow hedge at 30 June 2015 is 3.5 years.

Forward exchange contracts are also used to hedge the value of investments in certain foreign subsidiaries and affiliates by creating a liability in a currency in which we have a net equity position. The primary currency pair in this portfolio of forward exchange contracts is Euros and U.S. dollars.

In addition to the forward exchange contracts that are designated as hedges, we utilize forward exchange contracts that are not designated as hedges. These contracts are used to economically hedge foreign currency-denominated monetary assets and liabilities, primarily working capital. The primary objective of these forward exchange contracts is to protect the value of foreign currency-denominated monetary assets and liabilities from the effects of volatility in foreign exchange rates that might occur prior to their receipt or settlement. This portfolio of forward exchange contracts comprises many different foreign currency pairs, with a profile that changes from time to time depending on business activity and sourcing decisions.

The table below summarizes our outstanding currency price risk management instruments:

			30 June 2015		30 September 2014
				Years			Years
			US$	Average		US$	Average
			Notional	Maturity		Notional	Maturity
Forward Exchange Contracts:
	Cash flow hedges	$	4,375.9	.5	$	2,965.5	.7
	Net investment hedges		515.6	4.1		685.9	2.9
	Not designated		1,298.9	.4		381.5	.1
Total Forward Exchange Contracts		$	6,190.4	.8	$	4,032.9	1.0

In addition to the above, we use foreign currency-denominated debt to hedge the foreign currency exposures of our net investment in certain foreign subsidiaries. The designated foreign currency-denominated debt and related accrued interest included €757.6 million ($844.3) and Chinese Renminbi 1,108.6 million ($178.8) at 30 June 2015 and €879.3 million ($1,110.6) and Chinese Renminbi 900.9 million ($146.8) at 30 September 2014. The designated foreign currency-denominated debt is located on the balance sheet in the long-term debt and short-term borrowings line items.

Debt Portfolio Management

It is our policy to identify on a continuing basis the need for debt capital and evaluate the financial risks inherent in funding the Company with debt capital. Reflecting the result of this ongoing review, the debt portfolio and hedging program are managed with the objectives and intent to (1) reduce funding risk with respect to borrowings made by us to preserve our access to debt capital and provide debt capital as required for funding and liquidity purposes, and (2) manage the aggregate interest rate risk and the debt portfolio in accordance with certain debt management parameters.

Interest Rate Management Contracts

We enter into interest rate swaps to change the fixed/variable interest rate mix of our debt portfolio in order to maintain the percentage of fixed- and variable-rate debt within the parameters set by management. In accordance with these parameters, the agreements are used to manage interest rate risks and costs inherent in our debt portfolio. Our interest rate management portfolio generally consists of fixed-to-floating interest rate swaps (which are designated as fair value hedges), pre-issuance interest rate swaps and treasury locks (which hedge the interest rate risk associated with anticipated fixed-rate debt issuances and are designated as cash flow hedges), and floating-to-fixed interest rate swaps (which are designated as cash flow hedges). At 30 June 2015, the outstanding interest rate swaps were denominated in U.S. dollars. The notional amount of the interest rate swap agreements is equal to or less than the designated debt being hedged. When interest rate swaps are used to hedge variable-rate debt, the indices of the swaps and the debt to which they are designated are the same. It is our policy not to enter into any interest rate management contracts that lever a move in interest rates on a greater than one-to-one basis.

Cross Currency Interest Rate Swap Contracts

We enter into cross currency interest rate swap contracts when our risk management function deems necessary. These contracts may entail both the exchange of fixed- and floating-rate interest payments periodically over the life of the agreement and the exchange of one currency for another currency at inception and at a specified future date. These contracts effectively convert the currency denomination of a debt instrument into another currency in which we have a net equity position while changing the interest rate characteristics of the instrument. The contracts are used to hedge either certain net investments in foreign operations or nonfunctional currency cash flows related to intercompany loans. The current cross currency interest rate swap portfolio primarily consists of fixed-to-fixed swaps between U.S. dollars and offshore Chinese Renminbi, U.S. dollars and British Pound Sterling, U.S. dollars and Chilean Pesos, as well as U.S. dollars and Euros.

The following table summarizes our outstanding interest rate management contracts and cross currency interest rate swaps:

Credit Risk-Related Contingent Features

Certain derivative instruments are executed under agreements that require us to maintain a minimum credit rating with both Standard & Poor’s and Moody’s. If our credit rating falls below this threshold, the counterparty to the derivative instruments has the right to request full collateralization on the derivatives’ net liability position. The net liability position of derivatives with credit risk-related contingent features was $1.2 as of 30 June 2015 and $2.1 as of 30 September 2014. Because our current credit rating is above the various pre-established thresholds, no collateral has been posted on these liability positions.

Counterparty Credit Risk Management

We execute financial derivative transactions with counterparties that are highly rated financial institutions, all of which are investment grade at this time. Some of our underlying derivative agreements give us the right to require the institution to post collateral if its credit rating falls below the pre-established thresholds with Standard & Poor’s or Moody’s. These are the same agreements referenced in Credit Risk-Related Contingent Features above. The collateral that the counterparties would be required to post was $189.4 as of 30 June 2015 and $107.8 as of 30 September 2014. No financial institution is required to post collateral at this time, as all have credit ratings at or above the threshold.

Fair Value Measurements

Fair Value Measurements [Abstract]

Fair Value Measurements

10. FAIR VALUE MEASUREMENTS

Fair value is defined as an exit price, i.e., the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels as follows:

Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 — Inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the asset or liability.

Level 3 — Inputs that are unobservable for the asset or liability based on our own assumptions (about the assumptions market participants would use in pricing the asset or liability).

The methods and assumptions used to measure the fair value of financial instruments are as follows:

Derivatives

The fair value of our interest rate management contracts and forward exchange contracts are quantified using the income approach and are based on estimates using standard pricing models. These models take into account the value of future cash flows as of the balance sheet date, discounted to a present value using discount factors that match both the time to maturity and currency of the underlying instruments. The computation of the fair values of these instruments is generally performed by the Company. These standard pricing models utilize inputs which are derived from or corroborated by observable market data such as interest rate yield curves and currency spot and forward rates. Therefore, the fair value of our derivatives is classified as a level 2 measurement. On an ongoing basis, we randomly test a subset of our valuations against valuations received from the transaction’s counterparty to validate the accuracy of our standard pricing models. Counterparties to these derivative contracts are highly rated financial institutions.

Refer to Note 9, Financial Instruments, for a description of derivative instruments, including details on the balance sheet line classifications.

Long-term Debt

The fair value of our debt is based on estimates using standard pricing models that take into account the value of future cash flows as of the balance sheet date, discounted to a present value using discount factors that match both the time to maturity and currency of the underlying instruments. These standard valuation models utilize observable market data such as interest rate yield curves and currency spot rates. Therefore, the fair value of our debt is classified as a level 2 measurement. We generally perform the computation of the fair value of these instruments.

The carrying values and fair values of financial instruments were as follows:

		30 June 2015				30 September 2014
		Carrying Value		Fair Value		Carrying Value		Fair Value
Assets
Derivatives
	Forward exchange contracts	$	187.3	$	187.3	$	93.4	$	93.4
	Interest rate management contracts		130.8		130.8		78.3		78.3

Long-term debt, including current portion			4,775.4		4,992.2		4,889.8		5,130.7

The carrying amounts reported in the balance sheet for cash and cash items, trade receivables, payables and accrued liabilities, accrued income taxes, and short-term borrowings approximate fair value due to the short-term nature of these instruments. Accordingly, these items have been excluded from the above table.

The following table summarizes assets and liabilities measured at fair value on a recurring basis in the consolidated balance sheets:

Net periodic benefit cost is primarily included in cost of sales, selling and administrative expense, and pension settlement loss on our consolidated income statements. The amount of net periodic benefit cost capitalized in 2015 and 2014 was not material.

Our U.S. supplemental pension plan provides for a lump sum benefit payment option at the time of retirement, or for corporate officers, six months after their retirement date. Pension settlements are immediately recognized when cash payments exceed the sum of the service and interest cost components of net periodic pension cost of the plan for the fiscal year. The participant’s vested benefit is considered settled upon cash payment of the lump sum. For the three and nine months ended 30 June 2015, we recognized a pension settlement charge of $1.6 and $14.2, respectively, to accelerate recognition of a portion of actuarial losses deferred in accumulated other comprehensive loss associated with the U.S. supplemental pension plan.

Special termination benefits for the three and nine months ended 30 June 2015 are $.8 and $6.5, respectively, related to the business restructuring and cost reduction actions. In addition, curtailment losses for the three and nine months ended 30 June 2015 of $1.7 and $4.8, respectively, are also reflected in the business restructuring and cost reduction actions charge.

For the nine months ended 30 June 2015 and 2014, our cash contributions to funded pension plans and benefit payments under unfunded pension plans were $119.2 and $64.7, respectively. Total contributions for fiscal 2015 are expected to be approximately $130.0 to $150.0. During fiscal 2014, total contributions were $78.2.

Commitments and Contingencies	9 Months Ended
Commitments and Contingencies	Jun. 30, 2015
Commitments And Contingencies [Abstract]
Commitments and Contingencies	12. COMMITMENTS AND CONTINGENCIES Litigation We are involved in various legal proceedings, including competition, environmental, health, safety, product liability, and insurance matters. In September 2010, the Brazilian Administrative Council for Economic Defense (CADE) issued a decision against our Brazilian subsidiary, Air Products Brasil Ltda., and several other Brazilian industrial gas companies for alleged anticompetitive activities. CADE imposed a civil fine of R$179.2 million (approximately $58 at 30 June 2015) on Air Products Brasil Ltda. This fine was based on a recommendation by a unit of the Brazilian Ministry of Justice, whose investigation began in 2003, alleging violation of competition laws with respect to the sale of industrial and medical gases. The fines are based on a percentage of our total revenue in Brazil in 2003. We have denied the allegations made by the authorities and filed an appeal in October 2010 with the Brazilian courts. On 6 May 2014, our appeal was granted and the fine against Air Products Brasil Ltda. was dismissed. CADE has appealed that ruling and the matter remains pending. We, with advice of our outside legal counsel, have assessed the status of this matter and have concluded that, although an adverse final judgment after exhausting all appeals is possible, such a judgment is not probable. As a result, no provision has been made in the consolidated financial statements. We estimate the maximum possible loss to be the full amount of the fine of R$179.2 million (approximately $58 at 30 June 2015) plus interest accrued thereon until final disposition of the proceedings. While we do not expect that any sums we may have to pay in connection with this or any other legal proceeding would have a material adverse effect on our consolidated financial position or net cash flows, a future charge for regulatory fines or damage awards could have a significant impact on our net income in the period in which it is recorded. Environmental In the normal course of business, we are involved in legal proceedings under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA: the federal Superfund law); Resource Conservation and Recovery Act (RCRA); and similar state and foreign environmental laws relating to the designation of certain sites for investigation or remediation. Presently, there are approximately 37 sites on which a final settlement has not been reached where we, along with others, have been designated a potentially responsible party by the Environmental Protection Agency or are otherwise engaged in investigation or remediation, including cleanup activity at certain of our current and former manufacturing sites. We continually monitor these sites for which we have environmental exposure. Accruals for environmental loss contingencies are recorded when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. The consolidated balance sheets at 30 June 2015 and 30 September 2014 included an accrual of $82.5 and $86.2, respectively, primarily as part of other noncurrent liabilities. The environmental liabilities will be paid over a period of up to 30 years. We estimate the exposure for environmental loss contingencies to range from $82 to a reasonably possible upper exposure of $95 as of 30 June 2015. Actual costs to be incurred at identified sites in future periods may vary from the estimates, given inherent uncertainties in evaluating environmental exposures. Using reasonably possible alternative assumptions of the exposure level could result in an increase to the environmental accrual. Due to the inherent uncertainties related to environmental exposures, a significant increase to the reasonably possible upper exposure level could occur if a new site is designated, the scope of remediation is increased, a different remediation alternative is identified, or a significant increase in our proportionate share occurs. We do not expect that any sum we may have to pay in connection with environmental matters in excess of the amounts recorded or disclosed above would have a material adverse impact on our financial position or results of operations in any one year. PACE At 30 June 2015, $31.4 of the environmental accrual was related to the Pace facility. In 2006, we sold our Amines business, which included operations at Pace, Florida, and recognized a liability for retained environmental obligations associated with remediation activities at Pace. We are required by the Florida Department of Environmental Protection (FDEP) and the United States Environmental Protection Agency (USEPA) to continue our remediation efforts. We estimated that it would take 20 years to complete the groundwater remediation, and the costs through completion were estimated to range from $42 to $52. As no amount within the range was a better estimate than another, we recognized a pretax expense in fiscal 2006 of $42 as a component of income from discontinued operations and recorded an environmental accrual of $42 in continuing operations on the consolidated balance sheets. There has been no change to the estimated exposure range related to the Pace facility. We have implemented many of the remedial corrective measures at the Pace facility required under 1995 Consent Orders issued by the FDEP and the USEPA. Contaminated soils have been bioremediated, and the treated soils have been secured in a lined on-site disposal cell. Several groundwater recovery systems have been installed to contain and remove contamination from groundwater. We completed an extensive assessment of the site to determine how well existing measures are working, what additional corrective measures may be needed, and whether newer remediation technologies that were not available in the 1990s might be suitable to more quickly and effectively remove groundwater contaminants. Based on assessment results, we completed a focused feasibility study that has identified alternative approaches that may more effectively remove contaminants. We continue to review alternative remedial approaches with the FDEP. In the first quarter of 2015, we entered into a new Consent Order with the FDEP requiring us to continue our remediation efforts at the Pace facility. We expect the costs we will incur under the new Consent Order to be consistent with our previous estimates. PIEDMONT At 30 June 2015, $18.3 of the environmental accrual was related to the Piedmont site. On 30 June 2008, we sold our Elkton, Maryland, and Piedmont, South Carolina, production facilities and the related North American atmospheric emulsions and global pressure sensitive adhesives businesses. In connection with the sale, we recognized a liability for retained environmental obligations associated with remediation activities at the Piedmont site. This site is under active remediation for contamination caused by an insolvent prior owner. We are required by the South Carolina Department of Health and Environmental Control to address both contaminated soil and groundwater. Numerous areas of soil contamination have been addressed, and contaminated groundwater is being recovered and treated. We estimate that it will take until 2017 to complete source area remediation and another 15 years thereafter to complete groundwater recovery, with costs through completion estimated to be $24. We recognized a pretax expense in 2008 of $24 as a component of income from discontinued operations and recorded an environmental liability of $24 in continuing operations on the consolidated balance sheets. There has been no change to the estimated exposure. PASADENA At 30 June 2015, $11.7 of the environmental accrual was related to the Pasadena site. During the fourth quarter of 2012, management committed to permanently shutting down our polyurethane intermediates (PUI) production facility in Pasadena, Texas. In shutting down and dismantling the facility, we have undertaken certain obligations related to soil and groundwater contaminants. We have been pumping and treating groundwater to control off-site contaminant migration in compliance with regulatory requirements and under the approval of the Texas Commission on Environmental Quality (TCEQ). We estimate that the pump and treat system will continue to operate until 2042. We plan to perform additional work to address other environmental obligations at the site. This additional work includes remediating as required impacted soils, investigating groundwater west of the former PUI facility, performing post closure care for two closed RCRA surface impoundment units and establishing engineering controls. In 2012, we estimated the total exposure at this site to be $13. There has been no change to the estimated exposure. Guarantees During the third quarter of 2015, we entered into a 25% owned joint venture to supply oxygen and nitrogen to Saudi Aramco’s Jazan oil refinery and power plant in Saudi Arabia. Until 2020, an equity bridge loan has been provided to the joint venture to fund equity commitments, and we guaranteed the repayment of our 25% share of this loan. Our venture partner guaranteed repayment of their share. Our maximum exposure under the guarantee is approximately $100. Air Products has also entered into a sale of equipment contract with the joint venture to engineer, procure, and construct the industrial gas facilities that will supply gases to Saudi Aramco. We will provide bank guarantees to the joint venture of up to $326 to support our performance under the contract. The fair value of the guarantees is not material.

Share-Based Compensation [Abstract]

Share-Based Compensation

13. SHARE-BASED COMPENSATION

We have various share-based compensation programs, which include deferred stock units, stock options, and restricted stock. Under all programs, the terms of the awards are fixed at the grant date. We issue shares from treasury stock upon the payout of deferred stock units, the exercise of stock options, and the issuance of restricted stock awards. As of 30 June 2015, there were 5,115,244 shares available for future grant under our Long-Term Incentive Plan, which is shareholder approved.

Share-based compensation cost recognized in the consolidated income statements is summarized below:

			Three Months Ended				Nine Months Ended
			30 June				30 June
			2015		2014		2015		2014
	Before-Tax Share-Based Compensation Cost	$	12.5	$	9.1	$	37.3	$	32.5
	Income Tax Benefit		(4.4)		(3.2)		(13.1)		(11.4)
	After-Tax Share-Based Compensation Cost	$	8.1	$	5.9	$	24.2	$	21.1

Before-tax share-based compensation cost is primarily included in selling and administrative expense on our consolidated income statements. The amount of share-based compensation cost capitalized in 2015 and 2014 was not material.

Deferred Stock Units

During the nine months ended 30 June 2015, we granted 119,272 market-based deferred stock units. The market-based deferred stock units vest as long as the employee continues to be employed by the Company and upon the achievement of the performance target. The performance target, which is approved by the Compensation Committee, is the Company’s relative total shareholder return in relation to a defined peer group over the three-year performance period beginning 1 October 2014 and ending 30 September 2017.

The market-based deferred stock units had an estimated grant-date fair value of $194.51 per unit. The grant-date fair value was estimated using a Monte Carlo simulation model as these equity awards were tied to a market condition. The model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the grant and calculates the fair value of the awards. We generally expense the grant-date fair value of these awards on a straight line basis over the vesting period. The calculation of the fair value of market-based deferred stock units used the following assumptions:


Expected volatility	19.6	%
Risk-free interest rate	.9	%
Expected dividend yield	2.5	%

In addition, during the nine months ended 30 June 2015, we granted 138,010 time-based deferred stock units at a weighted-average grant-date fair value of $144.30.

Stock Options

During the nine months ended 30 June 2015, we granted 180,619 stock options at a weighted-average exercise price of $144.19 and an estimated fair value of $37.19 per option. The fair value of these options was estimated using a Black-Scholes option valuation model that used the following assumptions:


Expected volatility	30.3	%
Risk-free interest rate	2.2	%
Expected dividend yield	2.6	%
Expected life (in years)	7.5

Restricted Stock

During the nine months ended 30 June 2015, we issued 19,691 restricted shares at a weighted-average grant-date fair value of $144.09.

Noncontrolling Interests

16. NONCONTROLLING INTERESTS

INDURA S.A.

Redeemable Noncontrolling Interest

In 2012, we purchased a 64.8% controlling equity interest in the outstanding shares of Indura S.A. As part of the purchase agreement, the largest minority shareholder in Indura S.A. has the right to exercise a put option to require us to purchase up to a 30.5% equity interest during the two-year period beginning on 1 July 2015, at a redemption value equal to the greater of fair market value or the acquisition date value escalated by an inflation factor (the “floor value”). The put option is not accounted for separate from the minority interest shares that are subject to the put option. The redemption feature of the put option requires classification of the minority shareholder’s interest in the consolidated balance sheet outside of equity under the caption “Redeemable Noncontrolling Interest.”

Adjustments to the value of the redeemable noncontrolling interest due to the redemption feature are recognized as they occur. Currently, the floor value of the redemption feature is in excess of the fair value of the minority interest shares. Because the value of the redeemable noncontrolling interest cannot be less than the floor value, the attribution of net income between Air Products and the minority shareholders is adjusted so that the value of the redeemable noncontrolling interest is not less than the floor value.

The following is a summary of the changes in redeemable noncontrolling interest for the three and nine months ended 30 June:

	Three Months Ended
	30 June
	2015		2014
Balance at 31 March	$	280.0	$	343.6
Net income		6.1		1.1

Currency translation adjustment		(6.2)		(2.1)
Balance at 30 June	$	277.9	$	341.4

Dividends		(2.0)		(4.7)
Currency translation adjustment		(18.8)		(32.8)
Balance at 30 June	$	277.9	$	341.4

As of 30 June 2015, we have a 67.3% controlling equity interest in Indura S.A.

In July 2015, we completed the purchase of the 30.5% equity interest in our Indura S.A. subsidiary from the largest minority shareholder for $278 based on terms substantially consistent with the original purchase agreement. The purchase was funded by the issuance of commercial paper and will eliminate the redeemable noncontrolling interest balance on the statement of financial position.

Outstanding share-based awards of .2 million shares were antidilutive and therefore excluded from the computation of diluted earnings per share for the three and nine months ended 30 June 2015. Outstanding share-based awards of .7 and .8 million shares were antidilutive and therefore excluded from the computation of diluted earnings per share for the three and nine months ended 30 June 2014, respectively.

Disclosure Text Block Supplement [Abstract]
Supplemental Information	18. SUPPLEMENTAL INFORMATION Credit Agreement During fiscal 2013, we entered into a five-year $2,500.0 revolving credit agreement maturing 30 April 2018 with a syndicate of banks (the “2013 Credit Agreement”), under which senior unsecured debt is available to both the Company and certain of its subsidiaries. Effective 30 June 2014, the 2013 Credit Agreement was amended to increase the facility to $2,595.0. Effective 30 April 2015, the 2013 Credit Agreement was amended to decrease the facility to $2,405.0. The 2013 Credit Agreement provides a source of liquidity for the Company and supports its commercial paper program. The Company’s only financial covenant is a maximum ratio of total debt to total capitalization no greater than 70%. No borrowings were outstanding under the 2013 Credit Agreement as of 30 June 2015. Debt As of 30 June 2015, we have classified $250.0 of commercial paper as long-term debt because we have the ability to refinance the debt on a long-term basis under the 2013 Credit Agreement. Our current intent is to refinance this debt via the U.S. public debt market. On 12 February 2015, we issued a 1.0% Eurobond for €300 million ($335.3) that matures on 12 February 2025. The proceeds were used to repay a 3.875% Eurobond of €300 million ($335.9) that matured on 10 March 2015.

Segment Reporting, Disclosure of Entity's Reportable Segments [Abstract]

Business Segment Information

19. BUSINESS SEGMENT INFORMATION

The Company began operating under a new structure effective 1 October 2014. Our new reporting segments reflect the manner in which our chief operating decision maker reviews results and allocates resources. Except in the Corporate and other segment, each reporting segment meets the definition of an operating segment and does not include the aggregation of multiple operating segments. Our liquefied natural gas (LNG) and helium storage and distribution sale of equipment businesses are aggregated within the Corporate and other segment. The prior year information presented has been restated to conform with the fiscal year 2015 presentation.

The new reporting segments are:

Industrial Gases – Americas
Industrial Gases – EMEA (Europe, Middle East, and Africa)
Industrial Gases – Asia
Industrial Gases – Global
Materials Technologies
Energy-from-Waste
Corporate and other

Industrial Gases – Regional

The regional Industrial Gases (Americas, EMEA, Asia) segments include the results of our regional industrial gas businesses, which produce and sell atmospheric gases such as oxygen, nitrogen, and argon (primarily recovered by the cryogenic distillation of air) and process gases such as hydrogen, carbon monoxide, helium, syngas, and specialty gases. We supply gases to customers in many industries, including those in metals, glass, chemical processing, energy production and refining, food processing, metallurgical industries, medical, and general manufacturing. We distribute gases to our customers through a variety of supply modes including liquid or gaseous bulk supply delivered by tanker or tube trailer and, for smaller customers, packaged gases delivered in cylinders and dewars or small on-sites (cryogenic or noncryogenic generators). For large-volume customers, we construct an on-site plant adjacent to or near the customer’s facility or deliver product from one of our pipelines. We are the world’s largest provider of hydrogen, which is used by refiners to facilitate the conversion of heavy crude feedstock and lower the sulfur content of gasoline and diesel fuels.

Electricity is the largest cost component in the production of atmospheric gases, and natural gas is the principal raw material for hydrogen, carbon monoxide, and syngas production. We mitigate energy and natural gas prices contractually through pricing formulas, surcharges, and cost pass-through arrangements. The regional Industrial Gases segments also include our share of the results of several joint ventures accounted for by the equity method. The largest of these joint ventures operate in Mexico, Italy, South Africa, India, Saudi Arabia, and Thailand. Each of the regional Industrial Gases segments competes against global industrial gas companies as well as regional competitors. Competition is based primarily on price, reliability of supply, and the development of industrial gas applications. We derive a competitive advantage in locations where we have pipeline networks, which enable us to provide reliable and economic supply of products to larger customers.

Industrial Gases – Global

The Industrial Gases – Global segment includes cryogenic and gas processing equipment sales for air separation. The equipment is sold worldwide to customers in a variety of industries, including chemical and petrochemical manufacturing, oil and gas recovery and processing, and steel and primary metals processing. The Industrial Gases – Global segment also includes centralized global costs associated with management of all the Industrial Gases segments. These costs include Industrial Gases global administrative costs, product development costs, and research and development costs. We compete with a large number of firms for all the offerings included in the Industrial Gases – Global segment. Competition in the equipment businesses is based primarily on technological performance, service, technical know-how, price, and performance guarantees.

Materials Technologies

The Materials Technologies segment includes applications technology to make products that provide solutions to a broad range of global industries through chemical synthesis, analytical technology, process engineering, and surface science. This segment provides specialty gases, specialty chemicals, services, and equipment to the electronics industry primarily for the manufacture of silicon and compound semiconductors as well as liquid crystal (LCD) and other displays. The Materials Technologies segment also provides performance chemical solutions for the coatings, inks, adhesives, civil engineering, personal care, institutional and industrial cleaning, mining, oil field, polyurethane, and other industries. We compete in the businesses included in the Materials Technologies segment on a product-by-product basis against companies ranging from niche suppliers with a single product to large, vertically integrated companies. Competition is principally conducted on the basis of product performance, price, quality, reliability of product supply, technical innovation, service, and global infrastructure.

Energy-from-Waste

The Energy-from-Waste segment consists of two projects that are under construction in Tees Valley, United Kingdom. Once operational, these projects will process municipal solid waste to generate renewable power for customers under long-term contracts.

Corporate and other

The Corporate and other segment includes two on-going global businesses (our LNG sale of equipment business and our helium storage and distribution vessel sale of equipment business), the polyurethane intermediates business that was exited in early fiscal year 2014, and corporate support functions that benefit all the segments. Competition for the two sale of equipment businesses is based primarily on technological performance, service, technical know-how, price, and performance guarantees.
