Accounting Policies [Abstract]
Consolidation, Noncontrolling Interests and Basis of Presentation	NOTE 1 — CONSOLIDATION, NONCONTROLLING INTERESTS AND BASIS OF PRESENTATION Our financial statements include all of our majority-owned subsidiaries, except for certain subsidiaries that were deconsolidated during the period from May 31, 2010 through December 31, 2014. We reconsolidated such subsidiaries as of January 1, 2015 (refer to Note 2). We account for our investments in less-than-majority-owned joint ventures, for which we have the ability to exercise significant influence, under the equity method. Effects of transactions between related companies are eliminated in consolidation. Noncontrolling interests are presented in our consolidated financial statements as if parent company investors (controlling interests) and other minority investors (noncontrolling interests) in partially-owned subsidiaries have similar economic interests in a single entity. As a result, investments in noncontrolling interests are reported as equity in our consolidated financial statements. Additionally, our consolidated financial statements include 100% of a controlled subsidiary’s earnings, rather than only our share. Transactions between the parent company and noncontrolling interests are reported in equity as transactions between stockholders, provided that these transactions do not create a change in control. The accompanying unaudited consolidated financial statements have been prepared in accordance with Generally Accepted Accounting Principles in the U.S. (“GAAP”) for interim financial information and the instructions to Form 10-Q. In our opinion, all adjustments (consisting of normal, recurring accruals) considered necessary for a fair presentation have been included for the three and six months ended November 30, 2015 and 2014. For further information, refer to the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended May 31, 2015. Our business is dependent on external weather factors. Historically, we have experienced strong sales and net income in our first, second and fourth fiscal quarters comprising the three month periods ending August 31, November 30 and May 31, respectively, with weaker performance in our third fiscal quarter (December through February).

Text Block [Abstract]
Specialty Products Holding Corp. ("SPHC")	NOTE 2 — SPECIALTY PRODUCTS HOLDING CORP. (“SPHC”) Prior to May 31, 2010, Bondex International, Inc. (“Bondex”) and its parent, SPHC, were defendants in various asbestos-related bodily injury lawsuits filed in various state courts. These cases generally sought unspecified damages for asbestos-related diseases based on alleged exposures to asbestos-containing products. On May 31, 2010, Bondex and SPHC, filed voluntary petitions in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”) to reorganize under chapter 11 of the Bankruptcy Code. SPHC and Bondex took this action in an effort to permanently and comprehensively resolve all pending and future asbestos-related liability claims associated with Bondex and SPHC. Similarly, Republic Powdered Metals, Inc. (“Republic”) and NMBFiL, Inc. (“NMBFiL”), both of which are indirect wholly owned subsidiaries of RPM International Inc. (“RPM”), filed to reorganize under chapter 11 of the Bankruptcy Code in August 2014 to resolve all their pending and future asbestos-related liability claims. Both Republic and NMBFiL remained consolidated subsidiaries of RPM, considering the short-term nature of the bankruptcy and that RPM maintained control of them from a participating rights perspective. On December 10, 2014 a plan of reorganization was confirmed (the “Bankruptcy Plan”), and, effective as of December 23, 2014 (the “Effective Date”), Bondex, SPHC, Republic and NMBFiL emerged from bankruptcy. In accordance with the Bankruptcy Plan, trusts were established under Section 524(g) of the United States Bankruptcy Code (together, the “Trust”) and funded with first installments. Pursuant to the Bankruptcy Plan, the Trust assumed all liability and responsibility for current and future asbestos personal injury claims of Bondex, SPHC, Republic and NMBFiL, and such entities will have no further liability or responsibility for, and will (along with affiliates) be permanently protected from, such asbestos claims. The Trust was funded with $450.0 million in cash and a promissory note, bearing no interest and maturing on or before the fourth anniversary of the Effective Date (the “Bankruptcy Note”). The net present value of the Bankruptcy Note, or $331.5 million, is classified as other long-term liabilities in our consolidated financial statements at November 30, 2015. Borrowings under our $800.0 million revolving credit facility were used to fund the initial payment of $450.0 million, which is classified as long-term debt in our Consolidated Balance Sheets. A portion of the payments due under the Bankruptcy Note is secured by a right to the equity of SPHC, Republic and Bondex. The Bankruptcy Plan, and Bankruptcy Note, provide for the following additional contributions to the Trust: · On or before the second anniversary of the Effective Date, an additional $102.5 million in cash, RPM stock or a combination thereof (at our discretion in this and all subsequent cases) will be deposited into the Trust; · On or before the third anniversary of the Effective Date, an additional $120.0 million in cash, RPM stock or a combination thereof will be deposited into the Trust; and · On or before the fourth anniversary of the Effective Date, a final payment of $125.0 million in cash, RPM stock or a combination thereof will be deposited into the Trust. Total current and future contributions to the Trust are deductible for U.S. income tax purposes. Effective with the filing of the Notice of Entry of Order confirming the Bankruptcy Plan, which required the funding of the Trust, we regained control of SPHC and its subsidiaries, and accordingly, we have accounted for the event as a business combination. The funding of the Trust represents the total consideration transferred in the transaction, or $772.6 million. The opening balance sheets are based upon closing balances as of December 31, 2014 and results of operations have been included in our consolidated financial statements beginning on January 1, 2015 (the “Accounting Effective Date”) forward, as we concluded that the activity occurring between the date control was obtained (December 23, 2014) and the Accounting Effective Date was not significant. The fair values of SPHC and its subsidiaries have been determined as of January 1, 2015. Additionally, the fair value of RPM Holdco, of which SPHC owns 21.39% of the outstanding common stock, has been determined in order to account for our increase in ownership of the noncontrolling interest as an equity transaction. The total consideration has been allocated on a relative fair value basis between the noncontrolling interest in RPM Holdco, or approximately $208.4 million, and the net assets of SPHC, or approximately $564.2 million. The difference between the fair value of the noncontrolling interest in RPM Holdco and the carrying value of the noncontrolling interest was recorded as an equity transaction. The portion of the transaction accounted for as a business combination resulted in preliminary goodwill of $118.7 million and intangible assets of $176.0 million. The acquired intangible assets totaling $176.0 million comprise the following $118.7 million of customer and distributor relationships, $2.0 million of definite-lived tradenames, $52.7 million of indefinite-lived tradenames and $2.6 million of formulas. Income tax assets of $271.7 million were recorded in connection with the deductibility of current and future contributions to the Trust. Additionally, deferred tax liabilities of $72.3 million were recorded for the excess of the fair value book basis of certain assets over the corresponding tax basis. The fair values of net tangible assets, intangible assets and the noncontrolling interest were based upon valuations, which required our significant use of estimates and assumptions. While the valuations of consideration transferred and total assets acquired and liabilities assumed are substantially complete, measurement period adjustments may be recorded in the future as we finalize certain fair value estimates. The primary areas that remain preliminary relate to the fair values of deferred income taxes.

Accounting Changes And Error Corrections [Abstract]
New Accounting Pronouncements	NOTE 3 — NEW ACCOUNTING PRONOUNCEMENTS In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which establishes a comprehensive revenue recognition standard for virtually all industries in GAAP. Under the original issuance, the new standard would have applied to annual periods beginning after December 15, 2016, including interim periods therein. However, in August 2015, the FASB issued ASU 2015-14, which extends the standard effective date by one year and includes an option to apply the standard on the original effective date. We have not yet determined the effects, if any, adoption of this pronouncement may have on our consolidated financial statements. In April 2015, the FASB issued ASU 2015-03 "Interest-Imputation of Interest," which changes the presentation of debt issuance costs in financial statements and specifies that debt issuance costs related to a note shall be reported in the balance sheet as a direct deduction from the face amount of the note. The guidance does not change the current requirements surrounding the recognition and measurement of debt issuance costs, and the amortization of debt issuance costs will continue to be reported as interest expense. The guidance is effective for years and interim periods within those fiscal years beginning after December 15, 2015. Early adoption is allowed for all entities and the new guidance shall be applied to all prior periods retrospectively. We do not expect the adoption of this guidance to have a significant impact on our consolidated financial position and results of operations, although it will change the financial statement classification of the deferred debt cost. As of November 30, 2015, we had $3.0 million and $9.8 million of current and long-term net deferred debt costs, respectively. As of May 31, 2015, we had $3.0 million and $11.5 million of current and long-term net deferred debt costs, respectively. Current and long-term deferred debt costs are included in our Consolidated Balance Sheets and are reflected in prepaid expenses and other current assets, and other long-term assets, respectively. Under the new guidance, the net deferred debt costs would offset the carrying amount of the respective debt on the Consolidated Balance Sheets. In November 2015, the FASB issued ASU 2015-17, “Balance Sheet Classification of Deferred Taxes,” which will require entities to present deferred tax assets and liabilities as noncurrent in a classified balance sheet. This guidance simplifies the current guidance, which requires entities to separately present deferred tax assets and liabilities as current and noncurrent in a classified balance sheet. ASU 2015-17 is effective for fiscal years beginning after December 15, 2016, and interim periods within those years, and may be applied either prospectively to all deferred tax assets and liabilities or retrospectively to all periods presented. We are currently evaluating the impact this guidance will have on our consolidated financial statements.

We carry a portion of our marketable securities portfolio in long-term assets since they are generally held for the settlement of our general and product liability insurance claims processed through our wholly owned captive insurance subsidiaries. Marketable securities are composed of available-for-sale securities and are reported at fair value. Realized gains and losses on sales of investments are recognized in net income on the specific identification basis. Changes in the fair values of securities that are considered temporary are recorded as unrealized gains and losses, net of applicable taxes, in accumulated other comprehensive income (loss) within stockholders’ equity. Other-than-temporary declines in market value from original cost are reflected in operating income in the period in which the unrealized losses are deemed other than temporary. In order to determine whether other-than-temporary declines in market value have occurred, the duration of the decline in value and our ability to hold the investment are considered in conjunction with an evaluation of the strength of the underlying collateral and the extent to which the investment’s amortized cost or cost, as appropriate, exceeds its related market value. Gross gains realized on sales of investments were $2.1 million and $3.2 million for the quarters ended November 30, 2015 and 2014, respectively. During the three months ended November 30, 2015, we recognized gross realized losses on sales of investments of $0.1 million, while we recognized no such losses during the three months ended November 30, 2014. During the three months ended November 30, 2015, we recognized losses of approximately $2.5 million for securities deemed to have other-than-temporary impairments, while we recognized no such losses during the second quarter of fiscal 2015. These amounts are included in investment (income), net in the Consolidated Statements of Income. Gross gains realized on sales of investments were $4.6 million and $5.3 million for the six months ended November 30, 2015 and 2014, respectively. During the first six months of fiscal 2016, we recognized gross realized losses on sales of investments of $0.2 million, while we recognized no such losses during the first six months of fiscal 2015. During the six months ended November 30, 2015, we recognized losses of approximately $2.5 million for securities deemed to have other-than-temporary impairments, while we recognized no such losses during the first half of fiscal 2015. Summarized below are the securities we held at November 30, 2015 and May 31, 2015 that were in an unrealized loss position and that were included in accumulated other comprehensive income (loss), aggregated by the length of time the investments had been in that position: November 30, 2015 May 31, 2015 (In thousands) Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Total investments with unrealized losses $ 97,059 $ (7,889 ) $ 58,978 $ (3,815 ) Unrealized losses with a loss position for less than 12 months 55,461 (4,872 ) 32,693 (1,441 ) Unrealized losses with a loss position for more than 12 months 41,598 (3,017 ) 26,285 (2,374 ) We have reviewed all of the securities included in the table above and have concluded that we have the ability and intent to hold these investments until their cost can be recovered, based upon the severity and duration of the decline. Therefore, we did not recognize any other-than-temporary impairment losses on these investments. The unrealized losses generally relate to investments whose fair values at November 30, 2015 were less than 15% below their original cost. From time to time, we may experience significant volatility in general economic and market conditions. If we were to experience unrealized losses that were to continue for longer periods of time, or arise to more significant levels of unrealized losses within our portfolio of investments in marketable securities in the future, we may recognize additional other-than-temporary impairment losses. Such potential losses could have a material impact on our results of operations in any given reporting period. As such, we continue to closely evaluate the status of our investments and our ability and intent to hold these investments. The net carrying values of debt securities at November 30, 2015, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties.

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 5 — FAIR VALUE MEASUREMENTS Financial instruments recorded in the balance sheet include cash and cash equivalents, trade accounts receivable, marketable securities, notes and accounts payable, and debt. An allowance for anticipated uncollectible trade receivable amounts is established using a combination of specifically identified accounts to be reserved, and a reserve covering trends in collectibility. These estimates are based on an analysis of trends in collectibility and past experience, but are primarily made up of individual account balances identified as doubtful based on specific facts and conditions. Receivable losses are charged against the allowance when we confirm uncollectibility. All derivative instruments are recognized in our Consolidated Balance Sheets and measured at fair value. Changes in the fair values of derivative instruments that do not qualify as hedges and/or any ineffective portion of hedges are recognized as a gain or (loss) in our Consolidated Statements of Income in the current period. Changes in the fair value of derivative instruments used effectively as cash flow hedges are recognized in other comprehensive income (loss), along with the change in the value of the hedged item. We do not hold or issue derivative instruments for speculative purposes. The valuation techniques utilized for establishing the fair values of assets and liabilities are based on observable and unobservable inputs. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect management’s market assumptions. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value, as follows: Level 1 Inputs — Quoted prices for identical instruments in active markets. Level 2 Inputs — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. Level 3 Inputs — Instruments with primarily unobservable value drivers. The following tables present our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy.

The availability of inputs observable in the market varies from instrument to instrument and depends on a variety of factors including the type of instrument, whether the instrument is actively traded, and other characteristics particular to the transaction. For most of our financial instruments, pricing inputs are readily observable in the market, the valuation methodology used is widely accepted by market participants, and the valuation does not require significant management discretion. For other financial instruments, pricing inputs are less observable in the market and may require management judgment. At November 30, 2015, we had a foreign currency forward contract with a fair value of approximately $8.7 million, which is classified in other accrued liabilities in our Consolidated Balance Sheets. At May 31, 2015, we had a foreign currency forward contract with a fair value of approximately $6.4 million, which is classified in other accrued liabilities in our Consolidated Balance Sheets. Our foreign currency forward contract, which has not been designated as a hedge, was designed to reduce our exposure to the changes in the cash flows of intercompany foreign-currency-denominated loans related to changes in foreign currency exchange rates by fixing the functional currency cash flows. The foreign exchange rates included in the forward contract are based upon observable market data, but are not quoted market prices, and therefore, the forward currency forward contract is considered a Level 2 liability on the fair value hierarchy. The contingent consideration represents the estimated fair value of the additional variable cash consideration payable in connection with recent acquisitions that is contingent upon the achievement of certain performance milestones. We estimated the fair value using expected future cash flows over the period in which the obligation is expected to be settled, and applied a discount rate that appropriately captures a market participant's view of the risk associated with the obligation, which are considered to be Level 3 inputs. During the quarter ended November 30, 2015, we reversed approximately $14.5 million for contingent earnout targets that were not expected to be met, due to a delay in new business that will push the majority of orders previously anticipated for fiscal 2016 into our 2017 fiscal year. Additionally, during the first six months of fiscal 2016, we paid approximately $1.6 million for settlements of contingent consideration obligations relating to certain performance milestones that were established in prior periods and achieved during the current period. These amounts are reported in payments of acquisition-related contingent consideration in the Consolidated Statements of Cash Flows. The carrying value of our current financial instruments, which include cash and cash equivalents, marketable securities, trade accounts receivable, accounts payable and short-term debt approximates fair value because of the short-term maturity of these financial instruments. At November 30, 2015 and May 31, 2015, the fair value of our long-term debt was estimated using active market quotes, based on our current incremental borrowing rates for similar types of borrowing arrangements, which are considered to be Level 2 inputs. Based on the analysis performed, the fair value and the carrying value of our financial instruments and long-term debt as of November 30, 2015 and May 31, 2015 are as follows: At November 30, 2015 (In thousands) Carrying Value Fair Value Cash and cash equivalents $ 190,609 $ 190,609 Marketable equity securities 125,628 125,628 Marketable debt securities 22,787 22,787 Long-term debt, including current portion 1,676,064 1,724,147 At May 31, 2015 (In thousands) Carrying Value Fair Value Cash and cash equivalents $ 174,711 $ 174,711 Marketable equity securities 131,866 131,866 Marketable debt securities 22,904 22,904 Long-term debt, including current portion 1,656,075 1,783,962

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 8 — INCOME TAXES The effective income tax rate was 30.0% for the three months ended November 30, 2015 compared to an effective income tax rate of 30.2% for the three months ended November 30, 2014. The effective income tax rate was 29.7% for the six months ended November 30, 2015 compared to an effective income tax rate of 29.6% for the six months ended November 30, 2014. The effective tax rate for the three and six months ended November 30, 2015 and 2014 reflect variances from the 35% federal statutory rate primarily due to lower effective tax rate of certain of our foreign subsidiaries, the benefit of the domestic manufacturing deduction and the unfavorable impact of state and local taxes. At May 31, 2015, we determined that it was possible that we could repatriate approximately $419.1 million of undistributed foreign earnings in the foreseeable future. Accordingly, as of May 31, 2015, we recorded a deferred income tax liability of $108.5 million, which represented our estimate of the U.S income and foreign withholding tax associated with the $419.1 million of undistributed foreign earnings. Based on November 30, 2015 exchange rates, the amount of undistributed earnings that may be repatriated has been revalued to $401.5 million and the corresponding deferred tax liability has been reduced to $101.9 million. This reduction in the deferred tax liability is due to the impact of foreign exchange and is recorded in accumulated other comprehensive income (loss). We have not provided for U.S. income and foreign withholding taxes on the remaining foreign undistributed earnings because such earnings have been retained and reinvested by the foreign subsidiaries as of November 30, 2015. Accordingly, no provision has been made for U.S. income taxes or foreign withholding taxes, which may become payable if the remaining undistributed earnings of foreign subsidiaries were distributed to the U.S. Subsequent to November 30, 2015, on December 18, 2015, President Obama signed into law the Consolidated Appropriations Act, 2016 (the “Act”) that reinstated certain tax benefits and credits that had expired. The Act also made a number of the provisions permanent, including the research and development credit, extended others for five years and extended the remainder two years. Although we are still in the process of analyzing this new legislation, we do not expect this law to have a material impact on our consolidated financial results.

Stock Repurchase Program	NOTE 10 — STOCK REPURCHASE PROGRAM On January 8, 2008, we announced our authorization of a stock repurchase program under which we may repurchase shares of RPM International Inc. common stock at management’s discretion for general corporate purposes. Our current intent is to limit our repurchases to approximately one to two million shares per year, which would include amounts required to offset dilution created by stock issued in connection with our equity-based compensation plans and other repurchases. As a result of this authorization, we may repurchase shares from time to time in the open market or in private transactions at various times and in amounts and for prices that our management deems appropriate, subject to insider trading rules and other securities law restrictions. The timing of our purchases will depend upon prevailing market conditions, alternative uses of capital and other factors. We may limit or terminate the repurchase program at any time. During the three and six months ended November 30, 2015, we repurchased approximately 100,000 shares and 400,000 shares of our common stock under this program, respectively. These shares of common stock were repurchased during the current quarter and six month period for approximately $4.4 million and $17.2 million, respectively.

Pension Plans

Compensation And Retirement Disclosure [Abstract]
Pension Plans	NOTE 12 — PENSION PLANS We offer defined benefit pension plans, defined contribution pension plans, as well as several unfunded health care benefit plans primarily for certain of our retired employees. Historically, we estimated the service and interest cost components of net periodic pension and postretirement benefit cost by applying a single weighted-average discount rate, derived from the yield curve used to measure the benefit obligation at the beginning of the period. During the first quarter of the current fiscal year, we elected to change our approach in estimating service and interest cost by applying the split discount rate approach. Under the split discount rate approach, we estimate service and interest cost by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. We made this change in order to more precisely measure our service and interest costs, and the split discount rate approach achieves this by improving the correlation between projected benefit cash flows and the corresponding spot yield curve rates. This change will not affect the measurement of our total benefit obligation at our annual measurement date, as the change in service and interest cost is completely offset by deferred actuarial (gains)/losses that will arise at the next annual measurement date. As this change is treated as a change in estimate, the impact is reflected in the first quarter of the current fiscal year and prospectively, and historical measurements of service and interest cost were not affected. This change in estimate is anticipated to reduce our current year annual net periodic benefit expense by approximately $5.4 million for our U.S. Plans and by approximately $1.0 million for our non-U.S. plans. Accordingly, for the three months ended November 30, 2015, total service cost and interest cost for all plans was $9.6 million and $6.1 million, respectively, a reduction of $0.2 million and $1.4 million, respectively, as a result of implementing the new approach. For the six months ended November 30, 2015, total service cost and interest cost for all plans was $19.2 million and $12.2 million, respectively, a reduction of $0.4 million and $2.8 million, respectively, as a result of implementing the new approach. This resulted in an increase in income from continuing operations and net income for the three months ended November 30, 2015 of approximately $1.6 million and $1.1 million, respectively, and an increase in both basic and diluted earnings per share of $0.01. For the six months ended November 30, 2015, this resulted in an increase in income from continuing operations and net income of approximately $3.2 million and $2.2 million, respectively, and an increase in both basic and diluted earnings per share of $0.02. The following tables provide the retirement-related benefit plans’ impact on income before income taxes for the three and six months ended November 30, 2015 and 2014: U.S. Plans Non-U.S. Plans Three Months Ended Three Months Ended November 30, November 30, Pension Benefits 2015 2014 2015 2014 (In thousands) Service cost $ 8,202 $ 7,564 $ 1,067 $ 1,231 Interest cost 4,499 5,002 1,323 1,891 Expected return on plan assets (6,437 ) (6,034 ) (1,983 ) (2,296 ) Amortization of: Prior service cost 58 74 10 Net actuarial losses recognized 4,190 3,472 457 536 Settlement 91 Net Periodic Benefit Cost $ 10,512 $ 10,078 $ 955 $ 1,372 U.S. Plans Non-U.S. Plans Three Months Ended Three Months Ended November 30, November 30, Postretirement Benefits 2015 2014 2015 2014 (In thousands) Service cost $ - $ - $ 281 $ 313 Interest cost 59 66 221 308 Amortization of: Prior service (credit) (62 ) (62 ) Net actuarial (gains) losses recognized (34 ) 61 104 Net Periodic Benefit Cost $ (3 ) $ (30 ) $ 563 $ 725 U.S. Plans Non-U.S. Plans Six Months Ended Six Months Ended November 30, November 30, Pension Benefits 2015 2014 2015 2014 (In thousands) Service cost $ 16,404 $ 15,128 $ 2,134 $ 2,462 Interest cost 8,998 10,004 2,646 3,782 Expected return on plan assets (12,874 ) (12,068 ) (3,966 ) (4,592 ) Amortization of: Prior service cost 116 148 20 Net actuarial losses recognized 8,380 6,944 914 1,072 Settlement 91 Net Periodic Benefit Cost $ 21,024 $ 20,156 $ 1,819 $ 2,744 U.S. Plans Non-U.S. Plans Six Months Ended Six Months Ended November 30, November 30, Postretirement Benefits 2015 2014 2015 2014 (In thousands) Service cost $ - $ - $ 562 $ 626 Interest cost 118 132 442 616 Amortization of: Prior service (credit) (124 ) (124 ) Net actuarial (gains) losses recognized (68 ) 122 208 Net Periodic Benefit Cost $ (6 ) $ (60 ) $ 1,126 $ 1,450 Note that the information reflected above for the U.S. plans includes the Day-Glo plan as of its reconsolidation date of January 1, 2015. We previously disclosed in our financial statements for the fiscal year ended May 31, 2015 that we expected to contribute approximately $32.0 million to our retirement plans in the U.S. and approximately $5.7 million to plans outside the U.S. during the current fiscal year. As of November 30, 2015, we expect to contribute an additional $3.8 million to the Retirement Plan in the U.S., which will increase our total expected U.S. contributions for the 2016 fiscal year to $35.8 million.

Contingencies and Other Accrued

Commitments And Contingencies Disclosure [Abstract]
Contingencies and Other Accrued Losses	NOTE 13 — CONTINGENCIES AND OTHER ACCRUED LOSSES We provide, through our wholly owned insurance subsidiaries, certain insurance coverage, primarily product liability coverage, to our other subsidiaries. Excess coverage is provided by third-party insurers. Our product liability accruals provide for these potential losses as well as other uninsured claims. Product liability accruals are established based upon actuarial calculations of potential liability using industry experience, actual historical experience and actuarial assumptions developed for similar types of product liability claims, including development factors and lag times. To the extent there is a reasonable possibility that potential losses could exceed the amounts already accrued, we believe that the amount of any such additional loss would be immaterial to our results of operations, liquidity and consolidated financial position. We also offer warranties on many of our products, as well as long-term warranty programs at certain of our businesses, and have established product warranty liabilities. We review these liabilities for adequacy on a quarterly basis and adjust them as necessary. The primary factors that could affect these liabilities may include changes in performance rates as well as costs of replacement. Provision for estimated warranty costs is recorded at the time of sale and periodically adjusted, as required, to reflect actual experience. It is probable that we will incur future losses related to warranty claims we have received but that have not been fully investigated and related to claims not yet received. While our warranty liabilities represent our best estimates at November 30, 2015, we can provide no assurances that we will not experience material claims in the future or that we will not incur significant costs to resolve such claims beyond the amounts accrued or beyond what we may recover from our suppliers. Product warranty expense is recorded within selling, general and administrative expense within our Consolidated Statements of Income. Also, due to the nature of our businesses, the amount of claims paid can fluctuate from one period to the next. While our warranty liabilities represent our best estimates of our expected losses at any given time, from time-to-time we may revise our estimates based on our experience relating to factors such as weather conditions, specific circumstances surrounding product installations and other factors. The following table includes the changes in our accrued warranty balances: Three Months Ended Six Months Ended November 30, November 30, 2015 2014 2015 2014 (In thousands) Beginning Balance $ 10,112 $ 7,421 $ 11,663 $ 14,741 Deductions (1) (4,890 ) (5,066 ) (9,550 ) (19,741 ) Provision charged to SG&A expense 4,218 6,603 7,327 13,958 Ending Balance $ 9,440 $ 8,958 $ 9,440 $ 8,958 (1) Primarily claims paid during the year. In addition, like other companies participating in similar lines of business, some of our subsidiaries are involved in several proceedings relating to environmental matters. It is our policy to accrue remediation costs when it is probable that such efforts will be required and the related costs can be reasonably estimated. These liabilities are undiscounted and are not material to our financial statements during any of the periods presented. We were notified by the SEC on June 24, 2014, that we are the subject of a formal investigation pertaining to the timing of our disclosure and accrual of loss reserves in fiscal 2013 with respect to the previously disclosed U.S. Department Of Justice (the “DOJ”) and the U.S. General Services Administration (the “GSA”) Office of Inspector General investigation into compliance issues relating to Tremco Roofing Division’s GSA contracts. As previously disclosed, our audit committee completed an investigation into the facts and circumstances surrounding the timing of our disclosure and accrual of loss reserves with respect to the GSA and DOJ investigations, and determined that it was appropriate to restate our financial results for the first, second and third quarters of fiscal 2013. These restatements had no impact on our audited financial statements for the fiscal years ended May 31, 2013 or 2014. The audit committee’s investigation concluded that there was no intentional misconduct on the part of any of our officers. We are cooperating with the SEC in its ongoing investigation and continue to be engaged in discussions with the staff of the SEC’s Division of Enforcement (the “Staff”) concerning potential issues arising out of the SEC’s investigation. As previously disclosed, on October 26, 2015, we and our General Counsel received Wells notices from the SEC’s Division of Enforcement in connection with its investigation. A Wells notice is not a formal allegation or a finding of wrongdoing, but is a preliminary determination by the Staff that it may recommend to the SEC that a civil enforcement action or administrative proceeding be brought against the recipient. Our Wells notice also indicated that the Staff had preliminarily determined to recommend that the SEC pursue a clawback claim relating to incentive compensation payments paid to our Chief Executive Officer and Chief Financial Officer during the periods prior to the restatement. The Staff did not indicate an intention to recommend any charges against either of these officers. Under SEC procedures, a recipient of a Wells notice has an opportunity to respond in the form of a Wells submission that seeks to persuade the SEC that such an action should not be brought. In November 2015, we made a Wells submission to further explain RPM’s views concerning such matters and our belief that no enforcement action is warranted against us or our officers. We intend to contest any charges that may be brought. Any action by the SEC could result in sanctions against us and/or certain of our officers. A protracted investigation could impose substantial additional costs and distractions, regardless of its outcome. We have determined that it is probable that we will incur a loss relating to this matter and have estimated a range of potential loss. We have accrued at the low end of the range of loss, as no amount within the range is more likely to occur, and no amount within the estimated range of loss would have a material impact on our consolidated financial condition, results of operations or cash flows. A consolidated class-action complaint is pending against Rust-Oleum seeking to have a class certified and alleging breach of warranty, breach of contract and other claims regarding certain deck coating products of Rust-Oleum. Rust-Oleum is vigorously defending this action, including any attempts at class certification. At this time, we are unable to predict the outcome of this matter or provide any quantification of how the final resolution of this matter may impact our future consolidated financial condition, results of operations or cash flows.

Segment Reporting [Abstract]
Segment Information	NOTE 15 — SEGMENT INFORMATION As disclosed in our Annual Report on Form 10-K for the year ended May 31, 2015, during July 2015, our Board of Directors approved the realignment of certain businesses and management structure to recognize how we allocate resources and analyze the operating performance of our operating segments. This realignment did not change our reportable segments at May 31, 2015. During August 2015, we made the determination to combine our former RPM2-Industrial operating segment and our former SPHC operating segment into a single operating segment, called the “Specialty Products Group,” which is discussed in further detail below. Information for all periods presented has been recast to reflect this change. We operate a portfolio of businesses and product lines that manufacture and sell a variety of specialty paints, protective coatings and roofing systems, sealants and adhesives. We manage our portfolio by organizing our businesses and product lines into three reportable segments: the industrial reportable segment, the specialty reportable segment and the consumer reportable segment. Within each reportable segment, we aggregate operating segments or product lines that consist of individual companies or groups of companies and product lines, which generally address common markets, share similar economic characteristics, utilize similar technologies and can share manufacturing or distribution capabilities. Our seven operating segments represent components of our business for which separate financial information is available that is utilized on a regular basis by our chief operating decision maker in determining how to allocate the assets of the company and evaluate performance. These seven operating segments are each managed by an operating segment manager, who is responsible for the day-to-day operating decisions and performance evaluation of the operating segment’s underlying businesses. We evaluate the profit performance of our segments primarily based on income before income taxes, but also look to earnings (loss) before interest and taxes (“EBIT”) as a performance evaluation measure because interest expense is essentially related to acquisitions, as opposed to segment operations. Our industrial reportable segment products are sold throughout North America and also account for the majority of our international sales. Our industrial product lines are sold directly to contractors, distributors and end-users, such as industrial manufacturing facilities, public institutions and other commercial customers. The industrial reportable segment comprises three separate operating segments — Tremco Group, tremco illbruck Group and Performance Coatings Group. Products and services within this reportable segment include construction chemicals; roofing systems; weatherproofing and other sealants; and polymer flooring. Our specialty reportable segment products are sold throughout North America and a few international locations, primarily in Europe. Our specialty product lines are sold directly to contractors, distributors and end-users, such as industrial manufacturing facilities, public institutions and other commercial customers. The specialty reportable segment is a single operating segment, which offers products that include industrial cleaners; restoration services equipment; colorants; exterior finishes; edible coatings and specialty glazes for pharmaceutical and food industries; and other specialty OEM coatings. As discussed in Note 2, this segment includes the SPHC businesses, which were reconsolidated as of January 1, 2015. Our consumer reportable segment manufactures and markets professional use and do-it-yourself (“DIY”) products for a variety of mainly consumer applications, including home improvement and personal leisure activities. Our consumer segment’s major manufacturing and distribution operations are located primarily in North America, along with a few locations in Europe and other parts of the world. Our consumer reportable segment products are primarily sold directly to mass merchandisers, home improvement centers, hardware stores, paint stores, craft shops, cosmetic companies and through distributors. This reportable segment comprises three operating segments — Rust-Oleum Group, DAP Group and RPM2-Consumer Group. Products within this reportable segment include specialty, hobby and professional paints; nail care enamels; caulks; adhesives; silicone sealants and wood stains. In addition to our three reportable segments, there is a category of certain business activities and expenses, referred to as corporate/other, that does not constitute an operating segment. This category includes our corporate headquarters and related administrative expenses, results of our captive insurance companies, gains or losses on the sales of certain assets and other expenses not directly associated with any reportable segment. Assets related to the corporate/other category consist primarily of investments, prepaid expenses and headquarters’ property and equipment. These corporate and other assets and expenses reconcile reportable segment data to total consolidated income before income taxes, interest expense and earnings before interest and taxes; as well as identifiable assets, capital expenditures and depreciation and amortization. We reflect income from our joint ventures on the equity method, and receive royalties from our licensees. The following tables reflect the results of our reportable segments consistent with our management philosophy, and represent the information we utilize, in conjunction with various strategic, operational and other financial performance criteria, in evaluating the performance of our portfolio of businesses. Information for all periods presented has been recast to reflect the current year change in reportable segments.

(b) Interest (expense), net includes the combination of interest (expense) and investment income/(expense), net. (c) EBIT is defined as earnings (loss) before interest and taxes. We evaluate the profit performance of our segments based on income before income taxes, but also look to EBIT as a performance evaluation measure because interest expense is essentially related to acquisitions, as opposed to segment operations. We believe EBIT is useful to investors for this purpose as well, using EBIT as a metric in their investment decisions. EBIT should not be considered an alternative to, or more meaningful than, income before taxes as determined in accordance with GAAP, since EBIT omits the impact of interest and taxes in determining operating performance, which represent items necessary to our continued operations, given our level of indebtedness and ongoing tax obligations. Nonetheless, EBIT is a key measure expected by and useful to our fixed income investors, rating agencies and the banking community all of whom believe, and we concur, that this measure is critical to the capital markets' analysis of our segments' core operating performance. We also evaluate EBIT because it is clear that movements in EBIT impact our impact our ability to attract financing. Our underwriters and bankers consistently require inclusion of this measure in offering memoranda in conjunction with any debt underwriting or bank financing. EBIT may not be indicative of our historical operating results, nor is it meant to be predictive of potential future results.

(b) Interest (expense), net includes the combination of interest (expense) and investment income/(expense), net. (c) EBIT is defined as earnings (loss) before interest and taxes. We evaluate the profit performance of our segments based on income before income taxes, but also look to EBIT as a performance evaluation measure because interest expense is essentially related to acquisitions, as opposed to segment operations. We believe EBIT is useful to investors for this purpose as well, using EBIT as a metric in their investment decisions. EBIT should not be considered an alternative to, or more meaningful than, income before taxes as determined in accordance with GAAP, since EBIT omits the impact of interest and taxes in determining operating performance, which represent items necessary to our continued operations, given our level of indebtedness and ongoing tax obligations. Nonetheless, EBIT is a key measure expected by and useful to our fixed income investors, rating agencies and the banking community all of whom believe, and we concur, that this measure is critical to the capital markets' analysis of our segments' core operating performance. We also evaluate EBIT because it is clear that movements in EBIT impact our impact our ability to attract financing. Our underwriters and bankers consistently require inclusion of this measure in offering memoranda in conjunction with any debt underwriting or bank financing. EBIT may not be indicative of our historical operating results, nor is it meant to be predictive of potential future results.

[1]	The presentation includes a reconciliation of Income (Loss) Before Income Taxes, a measure defined by Generally Accepted Accounting Principles (GAAP) in the United States, to EBIT.
[2]	Interest (expense), net includes the combination of interest (expense) and investment income/(expense), net.
[3]	EBIT is defined as earnings (loss) before interest and taxes. We evaluate the profit performance of our segments based on income before income taxes, but also look to EBIT as a performance evaluation measure because interest expense is essentially related to acquisitions, as opposed to segment operations. We believe EBIT is useful to investors for this purpose as well, using EBIT as a metric in their investment decisions. EBIT should not be considered an alternative to, or more meaningful than, income before taxes as determined in accordance with GAAP, since EBIT omits the impact of interest and taxes in determining operating performance, which represent items necessary to our continued operations, given our level of indebtedness and ongoing tax obligations. Nonetheless, EBIT is a key measure expected by and useful to our fixed income investors, rating agencies and the banking community all of whom believe, and we concur, that this measure is critical to the capital markets' analysis of our segments' core operating performance. We also evaluate EBIT because it is clear that movements in EBIT impact our impact our ability to attract financing. Our underwriters and bankers consistently require inclusion of this measure in offering memoranda in conjunction with any debt underwriting or bank financing. EBIT may not be indicative of our historical operating results, nor is it meant to be predictive of potential future results.
