Basis of Presentation and Major Accounting Policies	1. BASIS OF PRESENTATION AND MAJOR ACCOUNTING POLICIES Refer to our 2015 Form 10-K for a description of major accounting policies. T here have been no significant changes to these accounting policies during the first six months of fiscal year 2016 other than those detailed in Note 2, New Account ing Guidance. Certain prior year information has been reclassified to conform to the fiscal year 2016 presentation. The consolidated financial statements of Air Products and Chemicals, Inc. and its subsidiaries (“we , ” “our , ” “us , ” the “Company , ” “Air Prod ucts , ” 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 p repared 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 disclose d 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.

Discontinued Operations [Abstract]
Discontinued Operations	2. DISCONTINUED OPERATIONS On 29 March 2016, the Board of Directors approved the Company’s exit of its Energy-from-Waste (EfW) business. As a result, efforts to start up and operate the two EfW projects located in Tees Valley, United Kingdom, have been discontinued. The decision to exit the business and stop development of the projects was based on continued difficulties encountered; and the Company’s conclusion, based on testing and analysis c ompleted during the second fiscal quarter of 2016, that significant additional time and resources would be required to make the projects operational. As a result, the EfW segment has been presented as a discontinued operation. Prior year EfW business segme nt information has been reclassified to conform to current year presentation. During the three months ended 31 March 2016, we recorded a loss of $945.7 ($846.6 after-tax) for the disposal of the business. Income tax benefits related only to one of the projects, as the other did not qualify for a local tax deduction. This loss includes $913 . 5 to write down plant assets, previously recorded as construction in progress, to their estimated net realizable value of $20.0 and $32.2 to record a liability f or plant disposition and other costs. We estimated the net realizable value of the projects assuming an orderly liquidation of assets capable of being marketed on a secondary equipment market based on market quotes and our experience with selling similar e quipment . An asset’s orderly liquidation value is the amount that could be realized from a liquidation sale, given a reasonable period of time to find a buyer , selling the asset in the existing condition where it is located and assuming the highest and bes t use of the asset by market participants . We recorded a valuation allowance of $ 58.0 and unrecognized tax benefits of $ 7.9 related to deferred tax assets on capital assets generated from the loss . The following table summarizes the carrying amount of the accrual for our actions to dispose of the EfW business at 31 March 2016: Asset Contract Actions Actions/Other Total Loss on disposal of business $ 913.5 $ 32.2 $ 945.7 Noncash expenses (913.5) - (913.5) 31 March 2016 $ - $ 32.2 $ 32.2 The results of discontinued operations are summarized below: Three Months Ended Six Months Ended 31 March 31 March 2016 2015 2016 2015 Loss before taxes $ (3.8) $ (2.5) $ (21.3) $ (4.8) Income tax provision (2.7) .6 .6 1.2 Loss from operations of discontinued operations (6.5) (1.9) (20.7) (3.6) Loss on disposal, net of tax (846.6) - (846.6) - Loss from Discontinued Operations, net of tax $ (853.1) $ (1.9) $ (867.3) $ (3.6) The loss from operations of discontinued operations primarily relates to land leases, commercial and administrative costs, and costs incurred related to project suspension activities.

New Accounting Guidance

New Accounting Guidance [Abstract]
New Accounting Guidance	3. NEW ACCOUNTING GUIDANCE Accounting Guidance Implemented in 2016 Balance Sheet Classification of Deferred Taxes In November 2015, the Financial Accounting Standards Board (FASB) issued guidance to simplify the presentation of deferred income taxes by requiring that all deferred tax liabilities and assets be classified as noncurrent on the balance sheet. As of the first quarter of fiscal year 2016, we adopted this guidance on a retrospective basis. Accordingly, prior year amounts have be en reclassified to conform to the current year presentation. The guidance, which did not change the existing requirement to net deferred tax assets and liabilities within a jurisdiction, resulted in a reclassification adjustment that increased noncurrent d eferred tax assets by $ 13.7 and decreased noncurrent deferred tax liabilities by $ 99.9 as of 30 September 2015. Discontinued Operations In April 2014, the FASB issued an update to change the criteria for determining which disposals qualify as a discontinue d 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 financia l results. We adopted this guidance prospectively for new disposals and new disposal groups classified as held for sale beginning in the first quarter of fiscal year 2016. This guidance had no impact on our consolidated financial statements upon adoption. As a result of actions taken during the second quarter of 2016, our Energy-from-Waste segment has been reported as a discontinued operation. Refer to Note 2, Discontinued Operations, for additional information. New Accounting Guidance to be Implemented 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 originally issued, this guidance was effective for us beginning in fiscal year 2018. In August 2015, the FASB deferred the effective date by one year, while providing the option to early adopt the standard on the original effective date. Accordingly, we will have the option to adopt the standard in either fiscal year 2018 or 2019. The guidance can be adopted either retrospectively or as a cumulative-effect adjustment as of the date of adoption. We are currently evaluating the adoption alternatives and im pact that this update will have 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 re trospectively 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 s tatements. 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. In August 2015, the FASB issued an update to incorporate the U.S. Securities and Exchange Commission (SEC) Staff guidance which allows debt issuance costs associated with a line-of - credit arrangement to be presented as a deferred a sset that is subsequently amortized over the term of the arrangement, regardless of whether there are any outstanding borrowings. This change in accounting principle will be effective beginning in fiscal year 2017 with early adoption permitted and must be applied retrospectively. This guidance will not have a significant impact on our consolidated financial statements . Leases In February 2016, the FASB issued guidance which requires lessees to recognize a right of use asset and lease liability on the balan ce sheet for all leases, including operating leases, with a term in excess of 12 months. The guidance also expands the quantitative and qualitative disclosure requirements. The guidance is effective in fiscal year 2020, with early adoption permitted , and mu st be applied using a modified retrospective approach. We are currently evaluating the impact of adopting this new guidance on the consolidated financial statements. Share-Based Compensation In March 2016, the FASB issued an update to simplify the accounting for employee share-based payments, including the income tax impacts, the classification on the statement of cash flows, and forfeitures. The amendments are effective for fiscal year 2018, with early adoption permitted. We are currently evaluati ng the impact this guidance will have on our consolidated financial statements. Derivative Contract Novations In March 2016, the FASB issued guidance to clarify that a change in the counterparty to a derivative instrument that has been designated as a h edging instrument does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. This guidance is effective in fiscal year 2018, with early adoption permitted. We do not expect adoption of this guidance to have a significant impact on our con solidated financial statements .

Restructuring and Related Activities [Abstract]
Business Separation [Text Block]	4 . MATERIALS TECHNOLOGIES SEPARATION On 16 September 2015, the Company announced plans to separate its Materials Technologies business into an independent publicly traded company and distribute to Air Products shareholders all of the shares of the new public company in a tax free distribution (a “spin-off”). Versum Materials, LLC, or Versum , was formed as the new company to hold the Materials Technologies business in November 2015 and is currently a wholly owned subsidiary of the Company. The Company expects to complete the work to prepare Versum to be a separate and independent company during fiscal year 2016 and is assessing market conditions to determin e favorability for a spin-off. Versum will be converted from a limited liability company to a Delaware corporation ( Ve rsum Materials, Inc.) prior to spin-off. For the three and six months ended 31 March 2016, we incurred separation costs of $7.4 and $19.4 , respectively, primarily related to legal and other advisory fees. These fees are reflected on the consolidated income statements as “Business separation costs.” The results of operations, financial condition, and cash flows of the Materials Technologies business continue to be presented within our consolidated financial statements as continuing operations. If the Board of Directors approves the final spin-off and the spin-off occurs, we expect the financial presentation of the historical results of the spun-off business will be reflected as a discontinued operation .

As a result of this reorganization, we incurred an expense of $207.7 throughout fiscal year 2015 for severance and other benefits and asset and associated contract actions. Of this charge, an expense of $55.4 ($38.2 after-tax, or $.18 per share) and $87.8 ($59.9 after-t ax, or $.27 per share ) was recognized during the three and six months ended 31 March 2015 , respectively.

Business Combinations	6. BUSINESS COMBINATION On 30 December 2014, we acquired our partner’s equity ownership interest in a liquefied atmospheric 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 six months ended 31 March 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 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 owns 25 % of the joint venture and guarantee s the repayment of its share of an equity bridge loan. ACWA also guarantees their share of the loan. As of 31 March 2016 , we have a noncurrent liability of $ 94.4 for our obligation to make future equity c ontributions based on our proportionate share of the advances received by the joint venture under the loan. In the first six months of fiscal 2016, we recorded a noncash transaction which resulted in an increase of $ 26.9 to our investment in net assets of and advances to equity affil iates, which has been excluded from the consolidated statements of cash flows. In total, we expect to invest approximately $ 100 in this joint venture. We determined that the joint venture is a variable interest entity, for which we are not the primary beneficiary. Air Products has also entered into a long -term sale of equipment contract with the joint venture to engineer, procure, and construct the industrial gas facilities that will su pply the gases to Saudi Aramco. In December 2015, we sold our investment in Daido Air Products Electronics, Inc. for $ 15.9 , which resulted in a g ain of $ .7 . The carrying value at time of sale included a $ 12.8 investment in net assets of and advances to equity affiliates and a $ 2.4 foreign currency t ranslation loss that had been deferred in accumu lated other comprehensive loss. In January 2016, we sold our investment in SembCorp Air Products ( HyCo ) Pte. Ltd. The transaction did not have a material impact on the financial statements .

Financial Instruments [Abstract]
Financial Instruments	10. 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 flo w 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 intercompa ny loans. This portfolio of forward exchange contracts consists prim a rily of Euros and U.S. dollars as well as Euros and British Po und Sterling . The maximum remaining term of any forward exchange contract currently outstanding and designated as a cash flow hedge at 31 March 2016 is 2.7 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 contract s 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 o f 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 cur rency 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: 31 March 2016 30 September 2015 Years Years US$ Average US$ Average Notional Maturity Notional Maturity Forward Exchange Contracts: Cash flow hedges $ 5,051.6 .5 $ 4,543.8 .5 Net investment hedges 442.0 3.8 491.3 4.0 Not designated 1,006.6 .5 863.3 .7 Total Forward Exchange Contracts $ 6,500.2 .7 $ 5,898.4 .9 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 deb t and related accrued interest include d € 543.8 million ($ 618.9 ) at 31 March 2016 and € 687.7 million ($ 768.4 ) at 30 September 2015 . The designated foreign currency - denominated debt is located on the balance sheet in the long -term debt and current portion of long-term debt 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 objectiv es 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 port folio 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 31 March 2016 , the outstanding interest rat e 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 de bt to which they are designated are the same. It is our policy not to enter into any interest rate management contracts which 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 currenc y 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 characteris tics 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 consists of fixed - to - fi xed swaps primarily between U.S. dollars and offshore Chinese Renminbi, U.S. dollars and Chilean Pesos, and U.S. dollars and British Pound Sterling. The following table summarizes our outstanding interest rate management contracts and cross currency intere st rate swaps: 31 March 2016 30 September 2015 Average Years Average Years US$ Average Receive Average US$ Average Receive Average Notional Pay % % Maturity Notional Pay % % Maturity Interest rate swaps (fair value hedge) $ 600.0 LIBOR 2.77 % 2.8 $ 600.0 LIBOR 2.77 % 3.3 Cross currency interest rate swaps (net investment hedge) $ 613.4 3.34 % 2.11 % 2.8 $ 609.9 4.06 % 2.61 % 3.2 Cross currency interest rate swaps (cash flow hedge) $ 1,105.8 4.60 % 2.70 % 3.7 $ 1,055.2 4.29 % 2.63 % 3.9 Cross currency interest rate swaps (not designated) $ 9.4 3.62 % .81 % 2.3 $ 12.9 3.12 % 3.08 % 4.1 The table below summarizes the fair value and balance sheet location of our outstanding derivatives: Balance Sheet 31 March 30 September Balance Sheet 31 March 30 September Location 2016 2015 Location 2016 2015 Derivatives Designated as Hedging Instruments: Forward exchange contracts Other receivables $ 107.0 $ 52.1 Accrued liabilities $ 54.9 $ 110.7 Interest rate management contracts Other receivables 15.2 17.6 Accrued liabilities - - Other noncurrent Other noncurrent Forward exchange contracts assets 39.5 68.5 liabilities 10.9 9.2 Other noncurrent Other noncurrent Interest rate management contracts assets 170.2 153.4 liabilities 2.3 .8 Total Derivatives Designated as Hedging Instruments $ 331.9 $ 291.6 $ 68.1 $ 120.7 Derivatives Not Designated as Hedging Instruments: Forward exchange contracts Other receivables $ 39.5 $ 3.2 Accrued liabilities $ 7.6 $ 3.9 Other noncurrent Other noncurrent Forward exchange contracts assets - 23.3 liabilities - .6 Other noncurrent Other noncurrent Interest rate management contracts assets - .8 liabilities - - Total Derivatives Not Designated as Hedging Instruments $ 39.5 $ 27.3 $ 7.6 $ 4.5 Total Derivatives $ 371.4 $ 318.9 $ 75.7 $ 125.2 Refer to Note 11, Fair Value Measurements, which defines fair value, describes the method for measuring fair value, and provides additional disclosures regarding fair value measurements.

(B) The impact of fair value hedges noted above was largely offset by gains and losses resulting from the impact of changes in related interest rates on recognized outstanding debt. (C) The impact of the non-designated hedges noted above was largely offset by gains and losses resulting from the impact of changes in exchange rates on recognized assets and liabilities denominated in nonfunctional currencies. The amount of cash flow hedges’ unrealized gains and losses at 31 March 2016 that are expected to be reclassified to earnings in the next twelve months is not material. The cash flows related to all derivative contracts are reported in the operating activities section of the consolidated statements of cash flows . 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-relate d contingent features was $ 7.9 as of 31 March 2016 and $ 0.2 as of 30 September 2015 . Because our current credit rating is above the various pre-established thresholds, no collateral has been posted on these liability positions . Counterparty Cre dit 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. The collateral that the counterparties would be required to post was $ 267.0 as of 31 March 2016 and $ 226.9 as of 30 September 2015 . No financial institution is required to post collateral at this time, as all have credit ratings at or above threshold .

Fair Value Measurements [Abstract]
Fair Value Measurements	11 . 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 o bservable 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 (a b out 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 usin g 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 derive d 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 10, Financial I nstruments, 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 c ash 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 ra te 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: 31 March 2016 30 September 2015 Carrying Value Fair Value Carrying Value Fair Value Assets Derivatives Forward exchange contracts $ 186.0 $ 186.0 $ 147.1 $ 147.1 Interest rate management contracts 185.4 185.4 171.8 171.8 Liabilities Derivatives Forward exchange contracts $ 73.4 $ 73.4 $ 124.4 $ 124.4 Interest rate management contracts 2.3 2.3 .8 .8 Long-term debt, including current portion 4,337.1 4,616.3 4,384.7 4,645.7 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. According ly, these items have been excluded from the above table.

RETIREMENT BENEFITS The components of net periodic benefit cos t for the defined benefit pension and other postretirement benefit plans for the three and six months ended 31 March 2016 and 2015 were as follows: Pension Benefits Other Benefits 2016 2015 2016 2015 Three Months Ended 31 March U.S. International U.S. International Service cost $ 9.3 $ 6.1 $ 10.6 $ 7.9 $ .6 $ .7 Interest cost 27.7 11.1 31.3 14.2 .5 .5 Expected return on plan assets (50.5) (19.6) (50.5) (19.1) - - Prior service cost amortization .8 (.1) .7 .1 - - Actuarial loss amortization 21.5 9.1 19.6 10.1 .1 .2 Settlements 2.6 - 12.6 - - - Curtailments - - 3.1 - - - Special termination benefits .6 - 2.1 .9 - - Other - .5 - .5 - - Net periodic benefit cost $ 12.0 $ 7.1 $ 29.5 $ 14.6 $ 1.2 $ 1.4 Pension Benefits Other Benefits 2016 2015 2016 2015 Six Months Ended 31 March U.S. International U.S. International Service cost $ 18.3 $ 12.3 $ 21.2 $ 16.1 $ 1.1 $ 1.4 Interest cost 55.4 22.7 62.5 29.2 1.0 1.1 Expected return on plan assets (101.0) (40.3) (101.0) (40.2) - - Prior service cost amortization 1.5 (.1) 1.4 .1 - - Actuarial loss amortization 42.6 18.3 39.4 20.6 .3 .4 Settlements 2.6 - 12.5 (.1) - - Curtailments - - 3.1 - - - Special termination benefits .6 - 4.8 .9 - - Other - 1.0 1.1 1.0 - - Net periodic benefit cost $ 20.0 $ 13.9 $ 45.0 $ 27.6 $ 2.4 $ 2.9 Net periodic benefit cost is primarily included in cost of sales and selling and administrative expense on our consolidated income statements. The amount of net periodic benefit cost capitalized in 2016 and 2015 was not material. Certain of our pension plans provide for a lump sum benefit payment option at the time of retirement, or for corporate officers, six months after their retirement date. A participant’s vested benefit is considered settled upon cash payment of the lump sum. We recognize pension settlement losses 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. For the six months ended 31 March 201 6 and 2015, we recognized $2.6 and $12. 6 of settlement losses, respectively , related to our U.S. supplemental pension plan. These settlement losses accelerated the recognition of a portion of actuarial losses deferred in accum ulated other comprehensive loss . Special termination b enefits for 2016 and 2015 are primarily related to the business restructuring and cost reduction actions ini tiated . In fiscal 2016, we changed our method to estimate the service cost and interest cost components of net periodic benefit costs for our majo r defined benefit pension plans. Historically, we estimated the service cost and interest cost components using a single weighted average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. We h ave elected to use a spot rate approach in the estimation of these components of benefit cost by applying the specific spot rates along the yield curve to the relevant projected cash flows, as we believe this provides a better estimate of service and inter est costs. We consider this change in rate assumption to be a change in estimate and, accordingly, are accounting for it prospectively starting in 2016. We expect that adoption of the spot rate approach will reduce our fiscal 2016 net periodic benefit cost by approximately $ 30 . This change does not affect the measurement of our total benefit obligation. The decrease in pension expense primarily resulted from the adoption of the spot rate approach to estimate service cost and interest cost and reduced plan participation due to severance actions, partially offset by the adoption of new mortality tables for our major plans. For the six months ended 31 March 2016 and 2015 , our cash contributions to funded pension plans and benefit payments under un funded pension plans were $ 60.2 and $ 95.4 , respectively. Total contributions for fiscal 2016 are expected to be approximately $ 100 to $ 120 . During fiscal 2015 , total contributions were $ 137.5 .

Commitments And Contingencies [Abstract]
Commitments and Contingencies	13. COMMITMENTS AND CONTINGENCIES Litigation We are involved in various legal proceedings, including commercial, 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 sev eral other Brazilian industrial gas companies for alleged anticompetitive activities. CADE imposed a civil fine of R$ 179.2 million (approxima tely $ 50 at 31 March 2016 ) 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 ha ve 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 matte r 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 a fter 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 $ 50 at 31 March 2016 ) plus interest accrued thereon until final dispositio n of the proceedings. While we do not expect that any sums we may have to pay in connection with this or any other legal p roceeding would have a material adverse effect on our consolidated financial position or net cash flows, a future charge for regulator y 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, t here 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 r emediation, 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 tha t a liability has been incurred and the amount of loss can be reasonably estimated . The consolidated balance sheets at 31 March 2016 and 30 September 2015 included an accrual of $ 77.0 and $ 80.6 , respectively, primarily as part of other noncurrent liabilities. The environmental liabilities will be paid over a period of up to 3 0 years. We estimate the exposure for environmental loss contingencies to range from $ 77 to a reasonably possible upper exposure of $ 91 as of 31 March 2016 . 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 lev el 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 rec orded or disclosed above would have a material adverse impact on our financial position or results of operations in any one year. PACE At 31 March 2016 , $ 30.5 of the environmental accrual was related to the Pace facility. In 2006, we sold our A mines 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 t he 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 completio n 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 operat ions 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 correcti ve measures at the Pace facility required under 1995 Consent Orders issued by t he 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 c ompleted 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 q uickly 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 remedi al 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 31 March 2016 , $ 18.0 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 r elated 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 contaminat ion have been addressed, and contaminated groundwater is being recovered and treated. We estimat e that it will take until 2019 to complete source area remediation with groundwater recovery and treatment, continuing through 2029 . Thereafter, we are expectin g this site to go into a state of monitored natural attenuation through 2047. 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 th e consolidated balance sheets. There ha ve been no significant change s to the estimated exposure. PA SADENA At 31 March 2016 , $ 10.6 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 conti nue 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, performin g 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 .

Share-Based Compensation [Abstract]
Share-Based Compensation	14. SHARE-BASED COMPENSATION We have various share-based compensation programs, which include de ferred stock units, stock options, and restricted stock. During the six months ended 31 March 2016, we granted deferred stock units 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 31 March 2016 , there were 4,774,072 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 Six Months Ended 31 March 31 March 2016 2015 2016 2015 Before-Tax Share-Based Compensation Cost $ 9.3 $ 12.9 $ 19.5 $ 24.8 Income Tax Benefit (3.3) (4.7) (6.8) (8.7) After-Tax Share-Based Compensation Cost $ 6.0 $ 8.2 $ 12.7 $ 16.1 Before-tax s hare-based compensation cost is primarily included in selling and administrative expense on our consolidated income statement s . T he amount of share-based compensation cost capitalized in 2016 and 2015 was not material. Deferred Stock Units During the six months ended 31 March 2016 , we granted 127,262 market-based deferred stock units. The market-based deferred stock units are earned out at the end of a performance period beginning 1 October 2015 and ending 30 September 2018, conditioned on the level of the Company’s total shareholder return in relation to a defined peer group over the three year performance period. The market-based deferred stock units had an estimated grant-da te fair value of $ 134.58 per unit, which was estimated using a Monte Carlo simulation model. The model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the grant and cal culates 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 20.5 % Risk-free interest rate 1.2 % Expected dividend yield 2.2 % In addition, during the six months ended 31 March 2016 , we granted 148,073 time - based deferred stock units at a weighted-a verage grant-date fair value of $ 136.96 . Restricted Stock During the six mont hs ended 31 March 2016 , we issu ed 32,920 restricted stock units at a grant-date fair value of $ 138.00 .
