Amendment Description	'RPM International Inc. (the “Company”) is filing this amended Quarterly Report on Form 10-Q/A because we determined that the consolidated financial statements contained in the Form 10-Q for the quarterly period ended November 30, 2012 and filed January 8, 2013 (“Original Form 10-Q”) should no longer be relied upon due to an error in the timing of the disclosure and accrual of certain loss reserves. These loss reserves were associated with our settlement of the previously disclosed General Services Administration (“GSA”) and Department of Justice (“DOJ”) investigation into compliance issues related to GSA contracts at our Tremco Roofing Division (also referred to herein as our Building Solutions Group Roofing Division) (the “GSA matter”). As a result of the error, the estimated loss contingency for the second quarter of fiscal 2013 was understated by $16.9 million, producing an overstatement of net income of $10.8 million and $18.0 million, respectively, for the three and six month period ended November 30, 2012. At the same time, our estimated loss contingency was understated by $11.4 million for the first quarter of fiscal 2013, and overstated by $28.3 million for the third quarter of fiscal 2013. As such, we are also restating our financial statements for the three month period ending August 31, 2012, and the three month period ended February 28, 2013 to address the error. After the restatement of the first and second quarters of fiscal 2013, the resulting charge in the third quarter of fiscal 2013 of $40.5 million was due to the application of a “multiplier” negotiated between the DOJ and the Company. The error did not impact the results for the nine months ended February 28, 2013 or the fiscal year ended May 31, 2013. The error was identified as a result of an investigation by the Audit Committee of the Company’s Board of Directors (the “Audit Committee”), with the assistance of independent advisors, into the timing of our third quarter of fiscal 2013 disclosure and accrual related to the GSA matter. The Audit Committee determined that the accounting errors described above did not result from intentional misconduct. The GSA matter is also the subject of a formal investigation by the Securities and Exchange Commission (the “SEC”). The Company is cooperating with the SEC in its ongoing investigation. The Audit Committee of the Company’s Board of Directors approved a restatement of the Company’s financial statements for the three-month and six-month periods ended November 30, 2012, by filing an amendment to the Original Form 10-Q. The error, including the specific line item on each of the Company’s financial statements that were restated, is described in greater detail in Note A1 contained in this Form 10-Q/A. The Company believes the restatement reflects a material weakness in the Company’s internal control over financial reporting and that its disclosure controls and procedures were not effective as of August 31, 2012 and November 30, 2012. The Company’s controls did not operate as designed to prevent material misstatements, due to unique factors that were only associated with the GSA matter. The Company has concluded that the unique factors related to the GSA matter contributed to a breakdown in communications, resulting in the material weakness. Based on developments that occurred during the third quarter of fiscal 2013 and the resulting disclosure of and accrual for the GSA matter, the material weakness no longer exists as of February 28, 2013.

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 on May 31, 2010 (please refer to Note 3). 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, except for certain subsidiaries that were deconsolidated, 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 the instructions to Form 10-Q and do not include all of the information and notes required by Generally Accepted Accounting Principles in the U.S. (“GAAP”) for complete financial statements. In our opinion, all adjustments (consisting of normal, recurring accruals) considered necessary for a fair presentation have been included for the three- and six-month periods ended November 30, 2012 and 2011. 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, 2012.
	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).
	Certain reclassifications have been made to prior year amounts to conform to the current year presentation.

INVESTMENT IN KEMROCK INDUSTRIES AND EXPORTS LTD.	'
	NOTE 2 — INVESTMENT IN KEMROCK INDUSTRIES AND EXPORTS LTD.
	During the second quarter of fiscal 2012, we increased our ownership in Kemrock Industries and Exports Limited (“Kemrock”) to over 20% of Kemrock’s outstanding shares of common stock. Kemrock is one of India’s leading manufacturers of high performance reinforced polymer composites. At that time, and as a result of our ownership exceeding 20% of their outstanding shares, we changed our method of accounting for our investment in Kemrock stock from an available for sale security to the equity method.
	Additionally, during fiscal 2012, we entered into three other, separate agreements with Kemrock. First, we agreed to loan Kemrock $15.0 million, which was to be repaid in cash, or alternatively, goods and commercial materials, no later than September 15, 2012. The loan is classified as a note receivable and is included in prepaid and other current assets in our Consolidated Balance Sheet. Second, we entered into a global depository receipt (“GDR”) Purchase Agreement with Kemrock, whereby we purchased 693,072 GDRs of Kemrock for an aggregate purchase price of approximately $7.2 million. The GDRs are included in our investment in Kemrock, which had a carrying value at the end of fiscal 2012 of $42.2 million, and are classified as other long-term assets in our Consolidated Balance Sheet. Lastly, during fiscal 2012 we invested $22.7 million in 5.5% convertible bonds issued by Kemrock. The bonds are convertible into ordinary shares or GDRs each representing one ordinary share of Kemrock stock, and may be converted at any time on or after June 4, 2012 and up to the close of business on June 12, 2017. Our investment in Kemrock’s convertible bonds is classified in other long-term assets in our Consolidated Balance Sheet.
	The economy and financial markets in India have experienced significant deterioration in recent months, including a devaluation of the Indian rupee versus the U.S. dollar. Additionally, the market value of shares of Kemrock common stock declined significantly, from 531.0 rupees per share as of May 31, 2012 to 56.70 rupees per share as of November 30, 2012. The majority of the decline in the market value of Kemrock shares began to occur during the month of August 2012. As a result of these factors, we determined that it was appropriate to record an impairment loss during the three and six month periods ended November 30, 3012 of approximately $10.1 million and $42.2 million, respectively, on our equity method investment. The loss is classified in other (income) expense, net in our Consolidated Statements of Income. Please see Note 11, where information related to this investment is more fully described.
	As of November 30, 2012, Kemrock had repaid approximately $5.0 million of the $15.0 million loan. We anticipate that we will receive approximately half of the remaining outstanding loan amount of $10.0 million in goods and materials by the end of the current fiscal year, and therefore have recorded a loss of $5.0 million for the amount deemed uncollectible during our first quarter ended August 31, 2012. The loss is classified in selling, general and administrative expense in our Consolidated Statements of Income.
	Lastly, during the three and six month periods ended November 30, 2012, we recorded a loss of approximately $0.8 million and $9.0 million, respectively, associated with the decline in the value of the conversion option feature associated with the 5.5% convertible bonds. Please see Note 6, where information related to this investment is more fully described.

	NOTE 3 — DECONSOLIDATION OF SPECIALTY PRODUCTS HOLDING CORP. (“SPHC”)
	On May 31, 2010, Bondex International, Inc. (“Bondex”) and its parent, SPHC, filed Chapter 11 reorganization proceedings in the United States Bankruptcy Court for the District of Delaware. SPHC is our wholly owned subsidiary. In accordance with Accounting Standards Codification (“ASC”) 810, when a subsidiary becomes subject to the control of a government, court, administrator, or regulator, deconsolidation of that subsidiary is generally required. We have therefore deconsolidated SPHC and its subsidiaries from our balance sheet as of May 31, 2010, and have eliminated the results of SPHC’s operations from our results of operations beginning on that date. We believe we have no responsibility for liabilities of SPHC and Bondex. As a result of the Chapter 11 reorganization proceedings, on a prospective basis we will continue to account for our investment in SPHC under the cost method.
	We had a net receivable from SPHC at May 31, 2010, that we expect may change before the bankruptcy proceedings have been finalized. The potential change relates to our indemnification of an insurer on appeal bonds pertaining to Bondex’s appeal of two asbestos cases that had been underway prior to the bankruptcy filing, neither of which are material in amount. During our 2012 third fiscal quarter, one of the appeal bonds was satisfied, and one remains outstanding. Included in the net amount due from SPHC are receivables and payables, which we concluded we have the right to report as a net amount based on several factors, including the fact that all amounts are determinable, the balances are due to and from our subsidiaries, and we have been given reasonable assurance that netting the applicable receivables and payables would remain legally enforceable. We analyzed our net investment in SPHC as of May 31, 2010, which included a review of our advances to SPHC, an assessment of the collectibility of our net receivables due from SPHC, and a computation of the gain to be recorded upon deconsolidation based on the carrying amount of our investment in SPHC. In accordance with GAAP, the gain on deconsolidation related to the carrying amount of net assets of SPHC at May 31, 2010, was calculated in accordance with ASC 810-10-40-5, as follows:
		a)	the aggregate of (1) the fair value of consideration received, (2) the fair value of any retained noncontrolling investment in the former subsidiary at the date the subsidiary is deconsolidated, and (3) the carrying amount of any noncontrolling interest in the former subsidiary; less
		b)	the carrying amount of the former subsidiary’s assets and liabilities.
	In determining the carrying value of any retained noncontrolling investment in SPHC at the date of deconsolidation we considered several factors, including analyses of cash flows combined with various assumptions relating to the future performance of this entity and a discounted value of SPHC’s recorded asbestos-related contingent obligations based on information available to us as of the date of deconsolidation. The discounted cash flow approach relies primarily on Level 3 unobservable inputs, whereby expected future cash flows are discounted using a rate that includes assumptions regarding an entity’s average cost of debt and equity, incorporates expected future cash flows based on internal business plans, and applies certain assumptions about risk and uncertainties due to the bankruptcy filing. Our estimates are based upon assumptions we believe to be reasonable, but which by nature are uncertain and unpredictable. As a result of this analysis, we determined that the carrying value of our retained interest in SPHC approximated zero.
	As a result of the combined analyses of each of the components of our net investment in SPHC, we recorded a net loss of approximately $7.9 million, which was reflected in Other Expense, Net, during the fourth fiscal quarter of the year ended May 31, 2010. No changes have been made to these amounts through November 30, 2012.

	NOTE 4 — NEW ACCOUNTING PRONOUNCEMENTS
	In June 2011, the FASB issued amended disclosure requirements for the presentation of other comprehensive income (OCI) and accumulated other comprehensive income (AOCI). OCI is comprised of costs, expenses, gains and losses that are included in comprehensive income but excluded from net income, and AOCI comprises the aggregated balances of OCI in equity. The amended guidance eliminated the option to present period changes (OCI) as part of the Statement of Changes in Equity. Under the amended guidance, all period changes (OCI) are to be presented either in a single continuous statement of comprehensive income, or in two separate but consecutive financial statements. Only summary totals are to be included in the AOCI section of the Statement of Changes in Equity. In December 2011, the FASB deferred the requirement to present reclassifications from AOCI on the face of the Consolidated Statement of Income. We adopted these provisions as of June 1, 2012. There was no impact on our consolidated financial results as the amendments relate only to changes in financial statement presentation.

	Marketable securities, included in other current and long-term assets, totaling $38.8 million and $96.4 million at November 30, 2012, respectively, and $30.5 million and $89.6 million at May 31, 2012, respectively, are composed of available-for-sale securities and are reported at fair value. In April 2012, we invested $22.7 million in 5.5% convertible bonds issued by Kemrock. The bonds are convertible into ordinary shares or global depositary receipts each representing one ordinary share of Kemrock stock, and may be converted at any time on or after June 4, 2012 and up to the close of business on June 12, 2017. Our investment in Kemrock convertible bonds is an available for sale security, which reflects the offsetting value of the discount on the bond as of the balance sheet date, and is classified in other long-term assets in our Consolidated Balance Sheet. We reclassified approximately $82.1 million and $76.0 million out of other current assets into long-term assets as of November 30, 2012 and May 31, 2012, respectively, in order to reflect the timeframe over which these assets are intended to be used.
	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 and losses realized on sales of investments were insignificant for the quarter ended November 30, 2012. Gross gains and losses realized on sales of investments were $1.9 million and $1.9 million, respectively, for the quarter ended November 30, 2011. During the second quarter of fiscal 2013 and 2012, we recognized losses of $0.5 million and $0.3 million, respectively, for securities deemed to have other-than-temporary impairments. These amounts are included in investment expense (income), net in the Consolidated Statements of Income.
	Gross gains and losses realized on sales of investments were $5.0 million and $0.4 million, respectively, for the six months ended November 30, 2012. Gross gains and losses realized on sales of investments were $3.8 million and $4.7 million, respectively, for the six months ended November 30, 2011. During the first half of fiscal 2013 and 2012, we recognized losses of $0.6 million and $0.7 million, respectively, for securities deemed to have other-than-temporary impairments.
	Summarized below are the securities we held at November 30, 2012 and May 31, 2012 that were in an unrealized loss position and that were included in accumulated other comprehensive income, aggregated by the length of time the investments had been in that position:
		November 30, 2012					May 31, 2012
	(In thousands)	Fair Value		Gross			Fair Value			Gross
				Unrealized						Unrealized
				Losses						Losses
	Total investments with unrealized losses	$	20,227	$	(743	)	$	43,772		$	(3,078	)
	Unrealized losses with a loss position for less than 12 months		19,531		(533	)		42,114			(2,596	)
	Unrealized losses with a loss position for more than 12 months		696		(210	)		1,658			(482	)
	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. Unrealized losses at November 30, 2012 were generally related to the volatility in valuations over the last several months for a portion of our portfolio of investments in marketable securities. The unrealized losses generally relate to investments whose fair values at November 30, 2012 were less than 15% below their original cost or have been in a loss position for less than six consecutive months. Although we have begun to see recovery in general economic conditions over the past year, if we were to experience continuing or significant 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, 2012, 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 MEASUREMENTS	'
	NOTE 7 — FAIR VALUE MEASUREMENTS
	Financial instruments recorded on 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, past experience, and 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 on our Consolidated Balance Sheet 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 Statement 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.

	Our marketable securities are composed of mainly available-for-sale securities, and are valued using a market approach based on quoted market prices for identical instruments. 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.
	Our cross-currency swap is a liability that has a fair value of $10.6 million at November 30, 2012, that was originally designed to fix our interest and principal payments in euros for the life of our unsecured 6.70% senior notes due November 1, 2015, which resulted in an effective euro fixed-rate borrowing of 5.31%. The basis for determining the rates for this swap included three legs at the inception of the agreement: the U.S. dollar (USD) fixed rate to a USD floating rate; the euro floating to euro fixed rate; and the dollar to euro basis fixed rate at inception. Therefore, we essentially exchanged fixed payments denominated in USD for fixed payments denominated in euros, paying fixed euros at 5.31% and receiving fixed USD at 6.70%. The ultimate payments are based on the notional principal amounts of 150 million USD and approximately 125 million euros. There will be an exchange of the notional amounts at maturity. The rates included in this swap are based upon observable market data, but are not quoted market prices, and therefore, the cross-currency swap is considered a Level 2 liability on the fair value hierarchy. Additionally, this cross-currency swap has been designated as a hedging instrument, and is classified as other long-term liabilities in our Consolidated Balance Sheets.
	Our investment in Kemrock 5.5% convertible bonds includes the fair value of the conversion option feature as of the balance sheet date, and is classified in other long-term assets in our Consolidated Balance Sheet. During the three and six month periods ended November 30, 2012, we recognized a loss of approximately $0.8 million and $9.0 million, respectively, resulting from the decline in the fair value of the conversion option feature associated with the bond, driven primarily from the decline in the market value of Kemrock common stock, from 531.0 rupees per share at May 31, 2012 to 56.70 rupees per share at November 30, 2012. The majority of the decline in the market value of Kemrock shares began to occur during the Month of August 2012. This amount is reflected in other expense (income) in the Consolidated Statements of Income.
	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, 2012 and May 31, 2012, 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, 2012 and May 31, 2012 are as follows:

REORGANIZATION PROCEEDINGS OF CERTAIN SUBSIDIARIES	'
	NOTE 8 — REORGANIZATION PROCEEDINGS OF CERTAIN SUBSIDIARIES
	General — Bondex and SPHC are defendants in various asbestos-related bodily injury lawsuits filed in various state courts. These cases generally seek unspecified damages for asbestos-related diseases based on alleged exposures to asbestos-containing products.
	On May 31, 2010, Bondex and its parent, SPHC, filed voluntary petitions for relief under Chapter 11 of the Bankruptcy Code in the U.S. Bankruptcy Court for the District of Delaware. SPHC is the parent company of Bondex and is also the parent company for various operating companies that are not part of the reorganization filing, including Chemical Specialties Manufacturing Corp.; Day-Glo Color Corp.; Dryvit Holdings, Inc.; Guardian Protection Products Inc.; Kop-Coat Inc.; TCI, Inc. and RPM Wood Finishes Group, Inc. SPHC and Bondex (the “filing entities”) took this action to permanently and comprehensively resolve all pending and future asbestos-related liability claims associated with Bondex and SPHC-related products. As a result of the filing, all Bondex and SPHC asbestos personal injury lawsuits have been stayed due to the imposition of an automatic stay applicable in bankruptcy cases, with the exception of the cases referenced in Note 3 with respect to which the stay was lifted. In addition, at the request of SPHC and Bondex, the bankruptcy court has entered orders staying all claims against RPM International Inc. and its affiliates that are derivative of the asbestos claims against SPHC and Bondex. Through the Chapter 11 proceedings, the filing entities intend ultimately to establish a trust in accordance with section 524(g) of the Bankruptcy Code and seek the imposition of a channeling injunction that will direct all future SPHC-related and Bondex-related claims to the trust. It is anticipated that the trust will compensate claims at appropriate values established by the trust documents and approved by the bankruptcy court. At this time, it is not possible to predict how long the proceedings will last, the form of any ultimate resolution or when an ultimate resolution might occur.
	Prior to the bankruptcy filing, the filing entities had engaged in a strategy of litigating asbestos-related products liability claims brought against them. Claims paid during the year ended May 31, 2010, prior to the bankruptcy filing, were $92.6 million, which included defense-related payments during the year of $42.6 million. With the exception of the appeal bond satisfied during our 2012 third fiscal quarter and the potential payment described in Note 3, no claims have been paid since the bankruptcy filing and it is not contemplated that any claims will be paid until a plan of reorganization is confirmed and an asbestos trust is established and operating.
	Prior to the Chapter 11 bankruptcy filing, we recorded asbestos-related contingent liabilities that included estimations of future costs, which by nature are subject to many uncertainties that may change over time, including (i) the ultimate number of claims filed; (ii) the amounts required to resolve both currently known and future unknown claims; (iii) the amount of insurance, if any, available to cover such claims, including the outcome of coverage litigation against the filing entities’ third-party insurers; (iv) future earnings and cash flow of the filing entities; (v) the impact of bankruptcies of other companies whose share of liability may be imposed on the filing entities under certain state liability laws; (vi) the unpredictable aspects of the litigation process including a changing trial docket and the jurisdictions in which trials are scheduled; (vii) the outcome of any such trials including judgments or jury verdicts, as a result of our more aggressive defense posture, which included taking selective cases to verdict; (viii) the lack of specific information in many cases concerning exposure to products for which one of our subsidiaries is responsible and the claimants’ diseases; (ix) potential changes in applicable federal and/or state law; and (x) the potential impact of various proposed structured settlement transactions or subsidiary bankruptcies by other companies, some of which are the subject of federal appellate court review, the outcome of which could have materially affected future asbestos-related liability estimates.
	As a result of their bankruptcy filing, SPHC and Bondex are precluded from paying dividends to shareholders and from making payments on any pre-bankruptcy filing accounts or notes payable that are due and owing to any other entity within the RPM group of companies (the “Pre-Petition Intercompany Payables”) or other pre-petition creditors during the pendency of the bankruptcy case, without the Bankruptcy Court’s approval. Moreover, no assurances can be given that any of the Pre-Petition Intercompany Payables will ever be paid or otherwise satisfied.
	When SPHC emerges from the jurisdiction of the Bankruptcy Court, the subsequent accounting will be determined based upon the applicable circumstances and facts at such time, including the terms of any plan of reorganization.
	SPHC has assessed its liquidity position as a result of the bankruptcy filing and believes that it can continue to fund its and its subsidiaries’ operating activities and meet its debt and capital requirements for the foreseeable future.
	Historical Asbestos Liability Reserve — In fiscal 2006, management retained Crawford & Winiarski (“C&W”), an independent, third-party consulting firm with expertise in the area of asbestos valuation work, to assist it in calculating an estimate of Bondex’s liability for unasserted-potential-future-asbestos-related claims. C&W’s methodology to project Bondex’s liability for unasserted-potential-future-asbestos-related claims included an analysis of: (a) a widely accepted forecast of the population likely to have been exposed to asbestos; (b) epidemiological studies estimating the number of people likely to develop asbestos-related diseases; (c) the historical rate at which mesothelioma incidences resulted in the payment of claims by Bondex; (d) the historical settlement averages to value the projected number of future compensable mesothelioma claims; (e) the historical ratio of mesothelioma-related indemnity payments to non-mesothelioma indemnity payments; and (f) the historical defense costs and their relationship with total indemnity payments. Based upon the results of this analysis, Bondex recorded an accrued liability for asbestos claims through 2016 as of May 31, 2006 of $421.3 million. This amount was calculated on a pretax basis and was not discounted for the time value of money.
	During the fiscal year ended May 31, 2008, the ten-year asbestos liability established as of May 31, 2006 was reviewed and evaluated. As part of that process, the credibility of epidemiological studies of Bondex’s mesothelioma claims, first introduced to management by C&W some two-and-one-half years earlier, was validated. At the core of the evaluation process, and the basis of C&W’s actuarial work on behalf of Bondex, is the Nicholson Study. The Nicholson Study is the most widely recognized reference in bankruptcy trust valuations, global settlement negotiations and the Congressional Budget Office’s work done on the proposed FAIR Act in 2006. Based on our ongoing comparison of the Nicholson Study projections and Bondex’s specific actual experience, which at that time continued to bear an extremely close correlation to the study’s projections, the asbestos liability projection was extended out to the year 2028. C&W assisted in calculating an estimate of our liability for unasserted-potential-future-asbestos-related claims out to 2028. C&W projected that the cost of extending the asbestos liability to 2028, coupled with an updated evaluation of Bondex’s current known claims to reflect its most recent actual experience, would be $288.1 million. Therefore, management added $288.1 million to the existing asbestos liability, which brought Bondex’s total asbestos-related balance sheet liabilities at May 31, 2008 to $559.7 million. On May 30, 2010, the day prior to the bankruptcy filing, Bondex had recorded an asbestos related product liability of $397.7 million.

CONTINGENCIES AND OTHER ACCRUED LOSSES	'
	NOTE 9 — 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 reserves provide for these potential losses as well as other uninsured claims.
	We also offer warranty programs at several of our industrial businesses and have established a product warranty liability. We review this liability for adequacy on a quarterly basis and adjust it as necessary. The primary factors that could affect this liability may include changes in the historical system performance rate as well as the 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 liability represents our best estimate at November 30, 2012, 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.
	The following table includes the changes in our accrued warranty balances:

	-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.
	During our fiscal year ended May 31, 2013, we recorded an adjustment to our current product liability reserves to remove the impact of claims that we determined will not likely be paid out over the next 12 months, which should have been included in the long-term product liability reserves as of May 31, 2012. As a result, long-term accrued product liability reserves (a component of other long-term liabilities on our Consolidated Balance Sheets) were increased by $27.0 million and $25.8 million, and current accrued product liability reserves (a component of accrued loss reserves on our Consolidated Balance Sheets) were decreased by an equal amount, in order to reflect this reclassification as of November 30, 2012 and May 31, 2012, respectively.
	During the second quarter of fiscal 2013, we recorded $16.9 million of additional accrual associated with the GSA matter. This is in addition to an $11.4 million accrual we recorded associated with this matter in the first quarter of fiscal 2013. The substantial majority of the accrual relates to the sale of products and services from 2002 to 2008. Our Tremco Roofing Division is in ongoing discussions with the U.S. Department of Justice (the “DOJ”) and the GSA aimed at resolving the investigation. We are cooperating with the investigation, which involves compliance with certain pricing terms and conditions of GSA contracts under which our Tremco Roofing Division sold products and services to the federal government. The $28.3 million accrual recorded at November 30, 2012 for this contingency represents our best estimate of the amount of probable loss that may result from this matter. In assessing our probable loss, we have considered the potentially disputed amounts under the relevant contracts, together with our understanding of policies for resolving such matters. It is reasonably possible that the actual amount of our loss may vary materially from the amount of the accrual. The ultimate loss related to this investigation may be subject to a “multiplier” that is determined by the DOJ, based on their consideration of the facts and circumstances related to this matter. This “multiplier” can range from one to three times the amount due to the government. The accrual for this contingency is classified in other accrued liabilities in our Consolidated Balance Sheets and the loss is classified as estimated loss contingency in our Consolidated Statements of Income as of and for the period ended November 30, 2012.

	Equity in Income of Unconsolidated Affiliates
	Beginning with our fiscal year ended May 31, 2007, we began purchasing shares of Kemrock Industries and Exports Limited (“Kemrock”) common stock. Kemrock is one of India’s leading manufacturers of high performance reinforced polymer composites, and is also part of a strategic alliance with certain of our subsidiaries for licensed manufacturing and supply of molded and pultruded gratings. By May 31, 2011, we had acquired a total of approximately 3.2 million shares of Kemrock common stock, for an accumulated cost approximating $24.2 million, which represented approximately 18% of Kemrock’s outstanding shares at that time. Our investment in Kemrock common stock had been classified in other long-term assets on our balance sheet and included with available-for-sale securities, which are carried at fair value based on quoted market prices.
	During fiscal 2012, we purchased approximately 870,000 additional shares of Kemrock common stock, which increased our ownership to 23% of Kemrock’s outstanding shares. Also during fiscal 2012, we entered into a GDR Purchase Agreement with Kemrock, whereby we purchased from Kemrock 693,072 GDRs of Kemrock for an aggregate purchase price of approximately $7.2 million. We account for our investment in the Kemrock GDRs as common stock equivalents within our total investment in Kemrock.
	Due to the presumption under GAAP that an entity with an ownership percentage greater than 20% has significant influence, and no other factors would refute that presumption, we changed our accounting for this investment to the equity method. Adjustments are made to our investment in order to recognize our share of Kemrock’s earnings as they occur, rather than as dividends or other distributions are received. Any changes in our proportionate share of the underlying equity of Kemrock, which could result from their issuance of additional equity securities, are recognized as increases or decreases in shareholders’ equity, net of any related tax effects.
	As discussed in Note 2, the economy and financial markets in India have experienced significant deterioration in recent months, including a devaluation of the Indian rupee versus the U.S. dollar. Additionally, the market value of shares of Kemrock common stock declined significantly, from 531.0 rupees per share as of May 31, 2012 to 56.70 rupees per share as of November 30, 2012. The majority of the decline in the market value of Kemrock shares began to occur during the month of August 2012. As a result of these factors, we determined that it was appropriate to record an impairment loss during the three and six month periods ended November 30, 2012 of approximately $10.1 million and $42.2 million, respectively, on our equity method investment. The loss is classified in other (income) expense, net in our Consolidated Statements of Income.
	Our investment in Kemrock is reported in our Consolidated Balance Sheet at its adjusted carrying value and classified as a long-term asset. Our investment in Kemrock had no carrying value at November 30, 2012 and a carrying value of $42.2 million at May 31, 2012.

INCOME_TAXES

INCOME TAXES	6 Months Ended
	Nov. 30, 2012
INCOME TAXES	'
	NOTE 12 — INCOME TAXES
	The effective income tax rate was 34.7% for the three months ended November 30, 2012 compared to an effective income tax rate of 29.2% for the three months ended November 30, 2011. The effective income tax rate was 42.5% for the six months ended November 30, 2012 compared to an effective income tax rate of 29.6% for the same period a year ago.
	For the three and six months ended November 30, 2012 and 2011, respectively, the effective tax rate was reduced below the federal statutory rate due to lower effective tax rates of certain of our foreign subsidiaries, the favorable impact of certain foreign operations on our U.S. taxes, the benefit of the domestic manufacturing deduction and due to net reductions to our reserves for contingencies, including interest thereon. Additionally, for the six months ended November 30, 2012 and 2011, decreases in the effective income tax rate resulted from a reduction in the United Kingdom income tax rate.
	For the three and six months ended November 30, 2012 and 2011, respectively, the effective tax rate increased principally as a result of the impact of valuation allowances associated with U.S. foreign tax credit carryforwards and certain foreign net operating losses, state and local income taxes, and non-deductible business operating expenses.
	Furthermore, for the three and six month periods ended November 30, 2012, the effective tax rate differed from the federal statutory rate as a result of valuation allowances related to losses associated with our investments in Kemrock and as a result of the impact on our effective tax rate in certain foreign jurisdictions where income tax benefits associated with net operating losses incurred by those foreign businesses are not recognized.
	As of November 30, 2012, we had unrecognized tax benefits of approximately $7.4 million, of which approximately $6.5 million would impact the effective tax rate, if recognized. We recognize interest and penalties related to unrecognized tax benefits in income tax expense. At November 30, 2012 the accrual for interest and penalties was $5.7 million. Unrecognized tax benefits, including interest and penalties, have been classified as other long-term liabilities unless expected to be paid in one year. We classified approximately $1.5 million of our reserve for uncertain tax positions, which includes associated interest and penalties, as a current liability as this amount could be reversed during the next 12 months. We do not anticipate any other significant changes to the total unrecognized tax benefits within the next 12 months.
	We, or our subsidiaries, file income tax returns in the U.S. and in various state, local and foreign jurisdictions. As of November 30, 2012 we are subject to U.S. federal income tax examinations for the fiscal years 2009 through 2012. In addition, with limited exceptions, we, or our subsidiaries, are generally subject to state and local or non-U.S. income tax examinations by tax authorities for the fiscal years 2005 through 2012.
	We are currently under examination, or have been notified of an upcoming tax examination for various Non-U.S. and U.S. jurisdictions including an ongoing Internal Revenue Service (“IRS”) examination of the company’s U.S. income tax returns for the fiscal 2009 and 2010 tax years. During the second quarter of fiscal 2013, the IRS proposed adjustments for the fiscal 2009 and 2010 years relating to, amongst other items, the deductibility of certain expenditures. We have evaluated the proposed adjustments for fiscal years 2009 and 2010 and have reached an informal agreement with the IRS. We expect to receive the final IRS assessment during the third the quarter of this fiscal year. We do not expect the final resolution of this IRS examination to have a material impact on our financial statements.
	Although it is possible that certain tax examinations could be resolved during the next 12 months, the timing and outcomes, other than for the ongoing IRS examination as described above, are uncertain.
	As of November 30, 2012, we have determined, based on the available evidence, that it is uncertain whether we will be able to recognize certain deferred tax assets. Therefore, we intend to maintain the tax valuation allowances recorded at November 30, 2012 for those deferred tax assets until sufficient positive evidence (for example, cumulative positive foreign earnings or additional foreign source income) exists to support their reversal. These valuation allowances relate to U.S. foreign tax credit carryforwards, U.S. capital loss carryforwards, certain foreign net operating losses and net foreign deferred tax assets. A portion of the valuation allowance is associated with deferred tax assets recorded in purchase accounting for prior year acquisitions.
	We include SPHC and its domestic subsidiaries (collectively, the “SPHC Group”) in our consolidated federal income tax return.
	We entered into a tax-cooperation agreement (the “Agreement”) with the SPHC Group, effective from June 1, 2010. Generally, the Agreement provides, amongst other items, that the federal income taxes of the SPHC Group are to be computed on a stand-alone separate return basis. The current portion of such income tax payable, if any, is due from the SPHC Group to us. Conversely, subject to the terms of the Agreement, income tax benefits associated with net operating loss or tax credit carryovers generated by the SPHC Group, if any, for the taxable year that benefits our consolidated income tax return for that taxable year are payable by us to the SPHC Group. Additionally, pursuant to the terms of the Agreement, a similar approach is applied to consolidated, combined or unitary state tax returns.

SEGMENT INFORMATION	'
	NOTE 15 — SEGMENT INFORMATION
	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 two reportable segments: the industrial reportable segment and the consumer reportable segment. Within each reportable segment, we aggregate several operating segments that consist of individual 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 five operating segments represent components of our business for which separate financial information is available that is utilized on a regular basis by our chief executive officer in determining how to allocate the assets of the company and evaluate performance. These five operating segments are each managed by an operating segment manager, who is responsible for the day-to-dayoperating decisions and performance evaluation of the operating segment’s underlying businesses.
	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. This reportable segment comprises three separate operating segments — Building Solutions Group, Performance Coatings Group and RPM2-Industrial Group. Products and services within this reportable segment include construction chemicals; roofing systems; weatherproofing and other sealants; polymer flooring; edible coatings and specialty glazes for pharmaceutical, cosmetic and food industries; and other specialty chemicals.
	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. Consumer segment products are sold directly to mass merchandisers, home improvement centers, hardware stores, paint stores, craft shops and to other smaller customers through distributors. This reportable segment comprises three operating segments — DAP Group, RPM2-Consumer Group and Rust-Oleum 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 two 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 either 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 and identifiable assets.
	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.

	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 only to amounts required to offset dilution created by stock issued in connection with our equity-based compensation plans, or approximately one to two million shares per year. 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 months ended November 30, 2012, we did not repurchase any shares of our common stock under this program.
