RPM INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

February 28, 2013

(Unaudited)

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 nine-month periods ended February 28, 2013 and February 29, 2012. 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.

During the third quarter of fiscal 2013, we recorded an adjustment to our current loss reserves to remove the impact of claims that we have determined will not likely be paid out over the next 12 months, which should have been included in the long-term accrued loss reserves as of May 31, 2012. As a result, long-term accrued loss reserves (a component of other long-term liabilities) were increased by $25.8 million, and current accrued loss reserves were decreased by an equal amount, in order to reflect this reclassification as of May 31, 2012.

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

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 accounted for as an available-for-sale security and is classified in other long-term assets in our Consolidated Balance Sheet. The convertible feature embedded in the convertible bonds is accounted for as a derivative under the guidance in ASC 815, “Derivatives and Hedging.”

At the time of our investment in Kemrock’s convertible bonds, Kemrock was in the midst of major capital expansion for new projects and upcoming technologies, and there were no indications of any adverse business, economic, competitive, or market factors. However, on August 8, 2012, the price of Kemrock’s common stock plunged below our carrying value, declining by approximately 40% from May 31, 2012. We later learned that the dramatic drop in Kemrock’s stock price was related to Kemrock’s announcement of declining sales and income, a liquidity problem at Kemrock that stemmed from its explosive growth, combined with the overall tightening of lending practices of banks and credit markets in India. At that time, we also learned that Kemrock was in the process of renegotiating its credit agreements with its banks. Compounding these difficulties for Kemrock was the deterioration in the exchange rate of the Indian rupee against the U.S. dollar and Euro, which had a negative impact on Kemrock’s gross profit margin and cash flow due to its procurement of the majority of its raw material supplies outside of India, but sales of its products in Indian rupees. The market value of shares of Kemrock common stock continued to decline significantly, and dropped from 531.0 rupees per share as of May 31, 2012 to 56.70 rupees per share as of November 30, 2012 and 52.90 rupees per share as of February 28, 2013. The majority of the decline in the market value of Kemrock shares began to occur during the month of August 2012.

We account for our equity method investment in Kemrock under ASC 323, “Investments – Equity Method and Joint Ventures.” As outlined in ASC 323-10-35-32, a decline in the quoted market price below the carrying amount when combined with other evidence of a loss in value may be indicative of a loss in value that is other than temporary. Acting upon the premise that a write-down may be required, we considered all available evidence to evaluate the realizable value of our equity investment, including the decline in the market price of shares of Kemrock stock, the financial condition and near term prospects of Kemrock, and the overall economic situation in India. As a result of these factors, we determined that it was appropriate to record an impairment loss during the three months ended August 31, 2012 of approximately $32.1 million of our equity method investment. As the value of the embedded conversion derivative is directly correlated to the market value of Kemrock stock, we wrote-down the embedded conversion feature derivative and recorded an approximate $8.2 million charge to earnings during the three months ended August 31, 2012.

After further monitoring of the economic environment in India and the continued declines in the price of Kemrock common stock during the three months ended November 30, 2012, we determined that it was appropriate to write off the remaining value of the convertible feature embedded in our investment in Kemrock convertible bonds, approximating $0.8 million, and the remaining equity investment in Kemrock, approximating $10.1 million, which represented our proportionate share of Kemrock losses under the equity method of accounting and the significant decline in the price of Kemrock stock during that time frame. The losses are classified in other (income) expense, net in our Consolidated Statements of Income. Please see Note 11, for additional information.

RPM INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

As of February 28, 2013, Kemrock had repaid approximately $5.4 million of the original $15.0 million loan. We anticipate that we will receive approximately $4.6 million in goods and materials by the end of the current fiscal year, and therefore previously 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.

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 therefore deconsolidated SPHC and its subsidiaries from our balance sheet as of May 31, 2010, and 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 during our 2013 third fiscal quarter, a provision for the remaining appeal bond was accrued and payment will be made during our 2013 fourth fiscal quarter. 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 February 28, 2013.

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. 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.

In February 2013, the FASB further amended the disclosure requirements for comprehensive income. The update requires companies to disclose items reclassified out of AOCI and into net income in a single location either in the notes to the consolidated financial statements or parenthetically on the face of the Statements of Operations. The change is effective for fiscal years, and interim periods within those years, beginning after December 15, 2012, and is to be applied prospectively. We will adopt these provisions on June 1, 2013, and do not expect the adoption of these updated disclosure requirements to affect our consolidated results of operations, financial condition or liquidity.

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 the decline in the market value of the bond, and is classified in other long-term assets in our Consolidated Balance Sheet.

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 $3.1 million and $0.2 million, respectively, for the quarter ended February 28, 2013. Gross gains and losses realized on sales of investments were $0.3 million and $0.1 million, respectively, for the quarter ended February 29, 2012. During the third quarter of fiscal 2012, we recognized losses of approximately $0.1 million for securities deemed to have other-than-temporary impairments, while there were no similar losses recognized during the third quarter of fiscal 2013. 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 $8.1 million and $0.6 million, respectively, for the nine months ended February 28, 2013. Gross gains and losses realized on sales of investments were $4.1 million and $4.8 million, respectively, for the nine months ended February 29, 2012. During the first nine months of fiscal 2013 and 2012, we recognized losses of $0.6 million and $0.8 million, respectively, for securities deemed to have other-than-temporary impairments.

Summarized below are the securities we held at February 28, 2013 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:

	February 28, 2013					May 31, 2012
(In thousands)	Fair Value		Gross Unrealized Losses			Fair Value		Gross Unrealized Losses
Total investments with unrealized losses	$	45,700	$	(3,562	)	$	43,772	$	(3,078	)
Unrealized losses with a loss position for less than 12 months		44,848		(3,357	)		42,114		(2,596	)
Unrealized losses with a loss position for more than 12 months		852		(205	)		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 February 28, 2013 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 February 28, 2013 were less than 15% below their original cost or have

12

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

been in a loss position for less than six consecutive months. Although we have seen 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 February 28, 2013, 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.

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 collectability 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 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 $10.9 million at February 28, 2013, 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 first half of fiscal 2013, we recognized a loss of approximately $9.0 million, 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 February 28, 2013 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 February 28, 2013 and May 31, 2012 are as follows:

	At February 28, 2013

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 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 are seeking to formulate a consensual plan of reorganization pursuant to Section 524(g) of the Bankruptcy Code. That plan of reorganization would establish a trust to compensate present and future asbestos-related claims at appropriate values set forth in the trust documents and approved by the bankruptcy court, and would also provide for the imposition of a channeling injunction that would direct all future SPHC-related and Bondex-related asbestos claims to the trust.

In January 2013, a trial to estimate the aggregate current and future asbestos liabilities of the filing entities was conducted before Judge Judith K. Fitzgerald in the United States Bankruptcy Court for the District of Delaware. Closing arguments were held on March 4, 2013, and the judge is expected to render an opinion by the end of May 2013. That opinion will be subject to appeal by any of the parties. At this time, it is not possible to predict how the judge will rule, the outcome of any appeal, how long the Chapter 11 proceedings will last, or the form of any ultimate resolution of the Chapter 11 proceedings.

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

RPM INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

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.

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. Product liability reserves 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. While it is reasonably possible that excess liabilities, if they were to occur, could be material to operating results in any given quarter or year of their recognition, we do not believe that it is reasonably possible that excess liabilities would have a material adverse effect on our long-term results of operations, liquidity or consolidated financial position.

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 February 28, 2013, 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.

As of February 28, 2013, based on discussions that occurred on March 29, 2013, we recorded a $68.8 million accrual associated with an investigation of our Building Solutions Group roofing contracts with the U.S. General Services Administration (the “GSA”). The substantial majority of the accrual relates to the sale of products and services from 2002 to 2008. Our Building Solutions Group is in ongoing settlement 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 Building Solutions Group roofing division sold products and services to the federal government. The accrual for this contingency represents our assessment 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. The actual amount of our loss, which remains subject to approval by the DOJ, may vary from the amount of the accrual. 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 February 28, 2013.

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

19

RPM INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

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. 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 convertible bonds is accounted for as an available-for-sale security and is classified in other long-term assets in our Consolidated Balance Sheet. The convertible feature embedded in the convertible bonds is accounted for as a derivative under the guidance in ASC 815, “Derivatives and Hedging.”

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.

We account for our equity method investment in Kemrock under ASC 323, “Investments – Equity Method and Joint Ventures.” As outlined in ASC 323-10-35-32, a decline in the quoted market price below the carrying amount when combined with other evidence of a loss in value may be indicative of a loss in value that is other than temporary. Acting upon the premise that a write-down of our investment in Kemrock may be required, we considered all available evidence to evaluate the realizable value of our equity investment, including a decline in the market price of shares of Kemrock stock, the financial condition and near term prospects of Kemrock, and the overall economic situation in India. As a result of these factors, we determined that it was appropriate to record an impairment loss during first half of fiscal 2013 of approximately $42.2 million on our equity method investment and a loss of approximately $9.0 million for the write-down of the embedded conversion derivative associated with our investment in Kemrock convertible bonds. The loss is classified in other (income) expense, net in our Consolidated Statements of Income. Please refer to 2, where information related to this investment is more fully described.

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 February 28, 2013 and a carrying value of $42.2 million at May 31, 2012.

Loss on Repositioning of Operations in Brazil

During the third quarter of fiscal 2013, we repositioned certain of our industrial segment operations in Brazil, resulting in a substantial liquidation of a subsidiary and a loss of approximately $6.1 million. Included in the loss was the write-off of the associated accumulated foreign currency translation. This non-cash charge was previously recorded as an unrealized foreign exchange loss in our currency translation account as a component of other comprehensive income.

NOTE 12 — INCOME TAXES

The effective income tax rate was 32.8% for the three months ended February 28, 2013 compared to an effective income tax rate of 30.7% for the three months ended February 29, 2012. The effective income tax rate was 48.0% for the nine months ended February 28, 2013 compared to an effective income tax rate of 29.6% for the same period a year ago.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

For the three and nine months ended February 28, 2013 and February 29, 2012, 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 research and development tax credit, and due to the benefit of the domestic manufacturing deduction. Additionally, for the nine months ended February 28, 2013 and February 29, 2012, decreases in the effective income tax rate resulted from a reduction in the United Kingdom income tax rate. Further, the effective income tax rate for the nine months ended February 29, 2012 decreased due to net reductions to our reserves for income tax contingencies, including interest thereon.

For the three and nine months ended February 28, 2013 and February 29, 2012, 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 nine month periods ended February 28, 2013, the effective tax rate differed from the federal statutory rate as a result of income tax benefits related to our strategic decision to reposition certain Brazilian business operations, 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, the tax effect of projected non-deductible costs associated with the DOJ and GSA accrual and due to net increases to our reserves for income tax contingencies, including interest thereon. Additionally, for the nine months ended February 28, 2013 the effective tax rate differed from the federal statutory rate as a result of increases in valuation allowances related to losses associated with our investments in Kemrock.

As of February 28, 2013, we had unrecognized tax benefits of approximately $8.8 million, of which approximately $8.0 million would impact the effective tax rate, if recognized. We recognize interest and penalties related to unrecognized tax benefits in income tax expense. At February 28, 2013 the accrual for interest and penalties was $5.5 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 $2.2 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 February 28, 2013 we are subject to U.S. federal income tax examinations for the fiscal years 2011 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 2006 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 return for the fiscal 2011 tax year. Although it is possible that certain tax examinations could be resolved during the next 12 months, the timing and outcomes are uncertain.

During the third quarter of fiscal 2013 we settled the IRS examination of the company’s U.S. income tax returns for the fiscal 2009 and 2010 tax years resulting in a net refund. The IRS adjustments related to, amongst other items, the deductibility of certain of our expenditures, exclusion of selective items of miscellaneous income and our research tax credit positions. The settlement did not have a material impact on our financial statements.

As of February 28, 2013, 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 February 28, 2013 for those deferred tax assets until sufficient positive evidence (for

21

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.

NOTE 13 — 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.

In our financial statements for the quarterly period ended November 30, 2012, we disclosed that we expected to contribute $5.4 million less to our retirement plans in the U.S., for a total of $24.5 million. As of February 28, 2013, this has not changed.

NOTE 14 — EARNINGS PER SHARE

The following table sets forth the reconciliation of the numerator and denominator of basic and diluted earnings per share, as calculated using the two-class method, for the nine months ended February 28, 2013 and February 29, 2012. For the three month periods ended February 28, 2013 and February 29, 2012, the treasury stock method was utilized for the purpose of computing basic and diluted earnings per share, as the result under the two-class method would have been anti-dilutive.

(1) For the three month period ended February 28, 2013, basic weighted-average shares outstanding are used in calculating diluted earnings per share as a result of the reported loss for the period. For the three month period ended February 29, 2012, approximately 2,811,000 shares of stock granted under stock-based compensation plans were excluded from the calculation of diluted EPS, as the effect would have been anti-dilutive.

(2) For the nine month periods ended February 28, 2013 and February 29, 2012, approximately 3,063,000 shares and 2,618,000 shares of stock, respectively, granted under stock-based compensation plans were excluded from the calculation of diluted EPS for those periods, as the effect would have been anti-dilutive.

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.

24

RPM INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Our six 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 six 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.

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 primarily 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.

NOTE 16 — 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 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 February 28, 2013, we did not repurchase any shares of our common stock under this program.

RPM INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

NOTE 18 — RECENTLY COMPLETED ACQUISITIONS

On September 5, 2012, we acquired Kirker Enterprises, Inc., a leading manufacturer of nail care enamels, coatings components and related products for the personal care industry. Based in Paterson, New Jersey, Kirker has annual sales in excess of $100 million. Kirker will be managed and reported by our RPM2 — Consumer operating segment.

On September 21, 2012, we acquired Synta, Inc., a producer and marketer of innovative and unique exterior wood deck and concrete restoration systems sold through leading national home centers and marketed under the brands of Deck Restore and Concrete Restore. Synta’s products also include a craft coatings line. Based in Clarkston, Georgia, Synta has annualized sales expected to exceed $40 million. Synta will be managed and reported by our Rust-Oleum operating segment.

The preliminary fair value of acquired goodwill and other intangible assets for the two acquisitions described above totaled approximated $160.9 million and $103.3 million, respectively. Additionally, the preliminary fair value of contingent consideration for these two acquisitions combined totaled approximately $63.5 million. Opening balance sheet valuations for these two recent acquisitions are ongoing. A final determination of the purchase price allocation will be made based upon the completion of the determination of the fair value of acquired tangible and intangible assets and our assessment of deferred income taxes.

NOTE 19 — DEBT

Pursuant to the provisions of ASC Topic No. 470-10-45, “Short-term Obligations Expected to be Refinanced,” at February 28, 2013, we classified $200.0 million of debt due within one year of the February 28, 2013 balance sheet date as long-term because we have both the intent and ability to repay such amounts with available borrowings under our $600.0 million 5-year revolving credit facility.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our Consolidated Financial Statements include the accounts of RPM International Inc. and its majority-owned subsidiaries, except for certain subsidiaries that were deconsolidated on May 31, 2010 (please refer to Note 1 to the Consolidated Financial Statements for further information). Investments in less-than-majority-owned joint ventures for which we have the ability to exercise significant influence over are accounted for under the equity method. Preparation of our financial statements requires the use of estimates and assumptions that affect the reported amounts of our assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We continually evaluate these estimates, including those related to our allowances for doubtful accounts; inventories; allowances for recoverable taxes; useful lives of property, plant and equipment; goodwill and other intangible assets; environmental, warranties and other contingent liabilities; income tax valuation allowances; pension plans; and the fair value of financial instruments. We base our estimates on historical experience, our most recent facts, and other assumptions that we believe to be reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of our assets and liabilities. Actual results, which are shaped by actual market conditions, may differ materially from our estimates.

We have identified below the accounting policies and estimates that are the most critical to our financial statements.

Revenue Recognition

Revenues are recognized when realized or realizable, and when earned. In general, this is when title and risk of loss pass to the customer. Further, revenues are realizable when we have persuasive evidence of a sales arrangement, the product has been shipped or the services have been provided to the customer, the sales price is fixed or determinable and collectibility is reasonably assured. We reduce our revenues for estimated customer returns and allowances, certain rebates, sales incentives and promotions in the same period the related sales are recorded.

We also record revenues generated under long-term construction contracts, mainly in connection with the installation of specialized roofing and flooring systems, and related services. In general, we account for long-term construction contracts under the percentage-of-completion method, and therefore record contract revenues and related costs as our contracts progress. This method recognizes the economic results of contract performance on a timelier basis than does the completed-contract method; however, application of this method requires reasonably dependable estimates of progress toward completion, as well as other dependable estimates. When reasonably dependable estimates cannot be made, or if other factors make estimates doubtful, the completed-contract method is applied. Under the completed-contract method, billings and costs are accumulated on the balance sheet as the contract progresses, but no revenue is recognized until the contract is complete or substantially complete.

Translation of Foreign Currency Financial Statements and Foreign Currency Transactions

Our reporting currency is the U.S. dollar. However, the functional currency for each of our foreign subsidiaries is its principal operating currency. We translate the amounts included in our Consolidated Statements of Income from our foreign subsidiaries into U.S. dollars at weighted-average exchange rates, which we believe are representative of the actual exchange rates on the dates of the transactions. Our foreign subsidiaries’ assets and liabilities are translated into U.S. dollars from local currency at the actual exchange rates as of the end of each reporting date, and we record the resulting foreign exchange translation adjustments in our Consolidated Balance Sheets as a component of accumulated other comprehensive income (loss). If the U.S. dollar strengthens, we reflect the resulting losses as a component of accumulated other comprehensive income (loss). Conversely, if the

30

U.S. dollar weakens, foreign exchange translation gains result, which favorably impact accumulated other comprehensive income. Translation adjustments may be included in net earnings in the event of a sale or liquidation of certain of our underlying foreign investments. If we determine that the functional currency of any of our foreign subsidiaries should be the U.S. dollar, our financial statements will be affected. Should this occur, we will adjust our reporting to appropriately account for any such changes.

As appropriate, we use permanently invested intercompany loans as a source of capital to reduce exposure to foreign currency fluctuations at our foreign subsidiaries. These loans, on a consolidated basis, are treated as being analogous to equity for accounting purposes. Therefore, foreign exchange gains or losses on these intercompany loans are recorded in accumulated other comprehensive income (loss). If we determine that the functional currency of any of our subsidiaries should be the U.S. dollar, we will no longer record foreign exchange gains or losses on such intercompany loans.

Goodwill

We test our goodwill balances at least annually, or more frequently as impairment indicators arise, at the reporting unit level. Our reporting units have been identified at the component level, which is the operating segment level or one level below our operating segments.

In the fourth quarter of our fiscal year ended May 31, 2012, we early adopted new Financial Accounting Standards Board (“FASB”) guidance that simplifies how an entity tests goodwill for impairment. It provides an option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, and whether it is necessary to perform the two-step goodwill impairment test.

We assess qualitative factors in each of our reporting units that carry goodwill. Among other relevant events and circumstances that affect the fair value of our reporting units, we assess individual factors such as:

• a significant adverse change in legal factors or the business climate;

• an adverse action or assessment by a regulator;

• unanticipated competition;

• a loss of key personnel; and

• a more-likely-than-not expectation that a reporting unit or a significant portion of a reporting unit will be sold or otherwise disposed of.

We assess these qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Under the new guidance, this quantitative test is required only if we conclude that it is more likely than not that a reporting unit’s fair value is less than its carrying amount.

In applying the first step of the quantitative test, we compare the fair value of a reporting unit to its carrying value. Calculating the fair market value of a reporting unit requires our use of estimates and assumptions. We use significant judgment in determining the most appropriate method to establish the fair value of a reporting unit. We estimate the fair value of a reporting unit by employing various valuation techniques, depending on the availability and reliability of comparable market value indicators, and employ methods and assumptions that include the application of third-party market value indicators and the computation of discounted future cash flows for a reporting unit’s annual projected earnings before interest, taxes, depreciation and amortization (“EBITDA”).

We evaluate discounted future cash flows for a reporting unit’s projected EBITDA. Under this approach, we calculate the fair value of a reporting unit based on the present value of estimated future cash flows. If the fair value of the reporting unit exceeds the carrying value of the net assets of the reporting unit, goodwill is not

31

impaired. An indication that goodwill may be impaired results when the carrying value of the net assets of a reporting unit exceeds the fair value of the reporting unit. At that point, the second step of the impairment test is performed, which requires a fair value estimate of each tangible and intangible asset in order to determine the implied fair value of the reporting unit’s goodwill. If the carrying value of a reporting unit’s goodwill exceeds its implied fair value, then we record an impairment loss equal to the difference.

In applying the discounted cash flow methodology, we rely on a number of factors, including future business plans, actual and forecasted operating results, and market data. The significant assumptions employed under this method include discount rates; revenue growth rates, including assumed terminal growth rates; and operating margins used to project future cash flows for a reporting unit. The discount rates utilized reflect market-based estimates of capital costs and discount rates adjusted for management’s assessment of a market participant’s view with respect to other risks associated with the projected cash flows of the individual reporting unit. Our estimates are based upon assumptions we believe to be reasonable, but which by nature are uncertain and unpredictable. We believe we incorporate ample sensitivity ranges into our analysis of goodwill impairment testing for a reporting unit, such that actual experience would need to be materially out of the range of expected assumptions in order for an impairment to remain undetected.

Our annual goodwill impairment analysis for fiscal 2012 did not result in any impairment loss. Should the future earnings and cash flows at our reporting units decline and/or discount rates increase, future impairment charges to goodwill and other intangible assets may be required.

Other Long-Lived Assets

We assess identifiable, non-goodwill intangibles and other long-lived assets for impairment whenever events or changes in facts and circumstances indicate the possibility that the carrying values of these assets may not be recoverable over their estimated remaining useful lives. Factors considered important in our assessment, which might trigger an impairment evaluation, include the following:

• significant under-performance relative to historical or projected future operating results;

• significant changes in the manner of our use of the acquired assets;

• significant changes in the strategy for our overall business; and

• significant negative industry or economic trends.

Additionally, we test all indefinite-lived intangible assets for impairment at least annually during our fiscal fourth quarter. Measuring a potential impairment of non-goodwill intangibles and other long-lived assets requires the use of various estimates and assumptions, including the determination of which cash flows are directly related to the assets being evaluated, the respective useful lives over which those cash flows will occur and potential residual values, if any. If we determine that the carrying values of these assets may not be recoverable based upon the existence of one or more of the above-described indicators or other factors, any impairment amounts would be measured based on the projected net cash flows expected from these assets, including any net cash flows related to eventual disposition activities. The determination of any impairment losses would be based on the best information available, including internal estimates of discounted cash flows; quoted market prices, when available; and independent appraisals, as appropriate, to determine fair values. Cash flow estimates would be based on our historical experience and our internal business plans, with appropriate discount rates applied. Our fiscal 2012 annual impairment tests of each of our indefinite-lived intangible assets did not result in any impairment loss.

Income Taxes

Our provision for income taxes is calculated using the liability method, which requires the recognition of deferred income taxes. Deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax

32

purposes and certain changes in valuation allowances. We provide valuation allowances against deferred tax assets if, based on available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

In determining the adequacy of valuation allowances, we consider cumulative and anticipated amounts of domestic and international earnings or losses, anticipated amounts of foreign source income, as well as the anticipated taxable income resulting from the reversal of future taxable temporary differences. We intend to maintain any recorded valuation allowances until sufficient positive evidence (for example, cumulative positive foreign earnings or additional foreign source income) exists to support a reversal of the tax valuation allowances.

Further, at each interim reporting period, we estimate an effective income tax rate that is expected to be applicable for the full year. Significant judgment is involved regarding the application of global income tax laws and regulations and when projecting the jurisdictional mix of income. Additionally, interpretation of tax laws, court decisions or other guidance provided by taxing authorities influences our estimate of the effective income tax rates. As a result, our actual effective income tax rates and related income tax liabilities may differ materially from our estimated effective tax rates and related income tax liabilities. Any resulting differences are recorded in the period they become known.

Contingencies

We are party to various claims and lawsuits arising in the normal course of business. Although we cannot precisely predict the amount of any liability that may ultimately arise with respect to any of these matters, we record provisions when we consider the liability probable and reasonably estimable. Our provisions are based on historical experience and legal advice, reviewed quarterly and adjusted according to developments. In general, our accruals, including our accruals for environmental, warranty, and tax liabilities, discussed further below, represent the best estimate of a range of possible losses. Estimating probable losses requires the analysis of multiple forecasted factors that often depend on judgments about potential actions by third parties, such as regulators, courts, and state and federal legislatures. Changes in the amounts of our loss provisions, which can be material, affect our Consolidated Statements of Income. While it is reasonably possible that excess liabilities, if they were to occur, could be material to operating results in any given quarter or year of their recognition, we do not believe that it is reasonably possible that excess liabilities would have a material adverse effect on our long-term results of operations, liquidity or consolidated financial position.

Our environmental-related accruals are similarly established and/or adjusted as more information becomes available upon which costs can be reasonably estimated. Actual costs may vary from these estimates because of the inherent uncertainties involved, including the identification of new sites and the development of new information about contamination. Certain sites are still being investigated; therefore, we have been unable to fully evaluate the ultimate costs for those sites. As a result, accruals have not been estimated for certain of these sites and costs may ultimately exceed existing estimated accruals for other sites. We have received indemnities for potential environmental issues from purchasers of certain of our properties and businesses and from sellers of some of the properties or businesses we have acquired. We also have purchased insurance to cover potential environmental liabilities at certain sites. If the indemnifying or insuring party fails to, or becomes unable to, fulfill its obligations under those agreements or policies, we may incur environmental costs in addition to any amounts accrued, which may have a material adverse effect on our financial condition, results of operations or cash flows.

Several of our industrial businesses offer extended warranty terms and related programs, and thus have established a corresponding warranty liability. Warranty expense is impacted by variations in local construction practices and installation conditions, including geographic and climate differences.

Additionally, our operations are subject to various federal, state, local and foreign tax laws and regulations that govern, among other things, taxes on worldwide income. The calculation of our income tax expense is based on

33

the best information available, including the application of currently enacted income tax laws and regulations, and involves our significant judgment. The actual income tax liability for each jurisdiction in any year can ultimately be determined, in some instances, several years after the financial statements have been published.

We also maintain accruals for estimated income tax exposures for many different jurisdictions. Tax exposures are settled primarily through the resolution of audits within each tax jurisdiction or the closing of a statute of limitation. Tax exposures and actual income tax liabilities can also be affected by changes in applicable tax laws, retroactive tax law changes, or other factors, which may cause us to believe revisions of past estimates are appropriate. Although we believe that appropriate liabilities have been recorded for our income tax expense and income tax exposures, actual results may differ materially from our estimates.

Allowance for Doubtful Accounts Receivable

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 collectability 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. Actual collections of trade receivables could differ from our estimates due to changes in future economic or industry conditions or specific customer’s financial conditions.

Inventories

Inventories are stated at the lower of cost or market, cost being determined on a first-in, first-out (FIFO) basis and market being determined on the basis of replacement cost or net realizable value. Inventory costs include raw materials, labor and manufacturing overhead. We review the net realizable value of our inventory in detail on an on-going basis, with consideration given to various factors, which include our estimated reserves for excess, obsolete, slow moving or distressed inventories. If actual market conditions differ from our projections, and our estimates prove to be inaccurate, write-downs of inventory values and adjustments to cost of sales may be required. Historically, our inventory reserves have approximated actual experience.

Marketable Securities

Marketable securities, included in other current and long-term assets, 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 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 an other-than-temporary decline in market value has occurred, the duration of the decline in value and our ability to hold the investment to recovery 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.

Pension and Postretirement Plans

We sponsor qualified defined benefit pension plans and various other nonqualified postretirement plans. The qualified defined benefit pension plans are funded with trust assets invested in a diversified portfolio of debt and equity securities and other investments. Among other factors, changes in interest rates, investment returns and the market value of plan assets can (i) affect the level of plan funding, (ii) cause volatility in the net periodic pension cost, and (iii) increase our future contribution requirements. A significant decrease in investment returns or the market value of plan assets or a significant decrease in interest rates could increase our net periodic pension costs

34

and adversely affect our results of operations. A significant increase in our contribution requirements with respect to our qualified defined benefit pension plans could have an adverse impact on our cash flow.

Changes in our key plan assumptions would impact net periodic benefit expense and the projected benefit obligation for our defined benefit and various postretirement benefit plans. Based upon May 31, 2012 information, the following tables reflect the impact of a 1% change in the key assumptions applied to our defined benefit pension plans in the U.S. and internationally:

BUSINESS SEGMENT INFORMATION

Our business is divided 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 six 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 six 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 corporate acquisitions, as opposed to segment operations.

Our industrial reportable segment’s 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

35

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 reportable segment’s major manufacturing and distribution operations are located primarily in North America, along with a few locations in Europe. Our consumer reportable segment’s products are sold throughout North America primarily to mass merchants, 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, interest expense and earnings before interest and taxes.

The following table reflects the results of our reportable segments consistent with our management philosophy, and represents the information we utilize, in conjunction with various strategic, operational and other financial performance criteria, in evaluating the performance of our portfolio of product lines.

(a) The presentation includes a reconciliation of Income (Loss) Before Income Taxes, a measure defined by generally accepted accounting principles (“GAAP”) in the U.S., to EBIT.

(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 corporate 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, operating income 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 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.

RESULTS OF OPERATIONS

Three Months Ended February 28, 2013

Net Sales On a consolidated basis, net sales of $843.7 million for the quarter ended February 28, 2013 improved 9.1%, or $70.1 million, over net sales of $773.6 million during the comparable prior year period. The organic growth in sales amounted to 1.9%, or $14.8 million, of the increase in the current quarter net sales versus net sales for the same period last year, and includes the impact of favorable foreign exchange of approximately 0.9% of the prior year period net sales. Six acquisitions executed over the past 12 months contributed approximately $55.3 million in net sales growth during the current quarter over the comparable prior year period, or approximately 7.2%.

Industrial segment net sales, which comprised approximately 63% of consolidated net sales for the quarter ended February 28, 2013, totaled $532.3 million, an increase of 6.1%, from $501.9 million during the comparable prior year period. The increase in the industrial segment’s net sales resulted from organic growth in sales of 1.6%, which includes the impact of favorable foreign exchange of 1.2%, and the impact of three acquisitions executed over the last twelve months, which contributed 4.5% of this segment’s current period growth in net sales versus net sales for the comparable prior year period.

Consumer segment net sales, which comprised approximately 37% of consolidated net sales for the quarter ended February 28, 2013, totaled $311.4 million, an increase of 14.6%, from $271.7 million during the same period a year ago. The improvement in this segment resulted from organic growth in sales of 2.5%, which includes the impact of favorable foreign exchange that amounted to 0.3% of the prior year net sales. Three acquisitions executed over the last year had a favorable impact of approximately 12.1% on this segment’s net sales during the current period versus the comparable prior year period.

Gross Profit Margin Our consolidated gross profit margin improved to 40.7% of net sales for the third quarter of fiscal 2013 versus a consolidated gross profit margin of 39.2% for the comparable period a year ago, reflecting the impact of our 1.9% growth in organic sales volume for the quarter ended February 28, 2013 versus the comparable prior year period, combined with the impact of favorable pricing initiatives instituted primarily during prior periods in order to offset escalating raw material costs.

Selling, General and Administrative Expenses (“SG&A”) Our consolidated SG&A increased to 37.7% of net sales for the quarter ended February 28, 2013 compared with 35.9% of net sales for the quarter ended February 29, 2012. The 180 basis point increase in SG&A as a percent of net sales versus the prior year reflects

37

the unfavorable impact of cross-currency transactions of approximately $6.4 million for the current quarter over the benefit booked in the comparable prior year period. Employee severance expense was approximately $3.0 million higher during the third quarter of fiscal 2013 than during the same period a year ago. The increase in SG&A expense also includes the impact of increased employee compensation-related expenses, including pension and postretirement benefit expense, increased advertising expense and outside professional services expense. Warranty expense for the quarter ended February 28, 2013 increased marginally from the amount recorded during the comparable prior year period. We anticipate that warranty expense will fluctuate from period to period, but will likely continue to slowly decline over the next few years.

Our industrial segment SG&A was approximately $29.6 million higher during the third quarter of fiscal 2013 versus the comparable prior year period, and higher as a percentage of net sales, reflecting the unfavorable foreign exchange impact from cross-currency transactions, representing approximately $7.5 million of the increase in SG&A in this segment. The increase in SG&A for this segment also includes the unfavorable impact of higher employee compensation and severance expense, bad debt, higher legal and distribution expense versus the comparable prior year period.

Our consumer segment SG&A was approximately $10.2 million higher during the third quarter of fiscal 2013 versus the comparable prior year period, but lower as a percentage of net sales in the third quarter of fiscal 2013 as compared with the same period a year ago, primarily reflecting the 12.1% growth in sales from recent acquisitions during the third quarter of fiscal 2013 versus the comparable prior year period, and the additional acquisition-related expense and SG&A generated by those acquisitions. SG&A expense for this segment also reflects the combination of higher legal and professional services expense, and higher advertising and marketing expense during the third quarter of fiscal 2013 versus the comparable prior year period.

SG&A expenses in our corporate/other category increased by $1.3 million during the third quarter of fiscal 2013 to $17.0 million from $15.7 million during the comparable prior year period. The increase in SG&A expense reflects the impact of higher legal and professional services expense, employee compensation and pension expense, partially offset by lower acquisition-related expense during the current quarter versus the same period a year ago.

We recorded total net periodic pension and postretirement benefit costs of $12.9 million and $8.7 million for the third quarter of fiscal 2013 and 2012, respectively. The $4.2 million increase in pension expense was primarily the result of $2.3 million of additional net actuarial losses incurred during the third quarter of fiscal 2013 versus the comparable prior year period and a $1.7 million increase in service and interest cost during the third quarter of fiscal 2013 versus the comparable prior year period. In addition, a lower expected return on plan assets had an unfavorable impact on pension expense of approximately $0.2 million for the current period versus the prior year period. We expect that pension expense will fluctuate on a year-to-year basis, depending primarily upon the investment performance of plan assets and potential changes in interest rates, but such changes are not expected to be material to our consolidated financial results. See Note 13, “Pension Plans,” for additional information regarding these benefits.

Estimated Loss Contingency During the quarter ended February 28, 2012, we recorded a $68.8 million accrual associated with settlement discussions that we are currently having with the DOJ and the GSA Office of Inspector General aimed at resolving an existing investigation. We have cooperated, and continue to cooperate, with the investigation, which involves our compliance with certain pricing terms and conditions of our GSA Multiple Award Schedule contracts under which the roofing division of our Building Solutions Group sold products and services to the federal government. The accrual for this contingency represents our assessment of the amount of probable loss that may result from this matter. The substantial majority of the probable loss relates to the sale of products and services in the period from 2002 to 2008. 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. The actual amount of our loss under the terms of any settlement may vary from the amount of the accrual.

38

Interest Expense Interest expense was $20.5 million for the third quarter of fiscal 2013 versus $17.9 million for the same period a year ago. Higher average borrowings, related to recent acquisitions, increased interest expense during this year’s third quarter by approximately $3.5 million versus the same period a year ago. Excluding acquisition-related borrowings, lower average borrowings year-over-year decreased interest expense by approximately $0.8 million. Lower interest rates, which averaged 5.30% overall for the third quarter of fiscal 2013 compared with 6.11% for the same period of fiscal 2012, decreased interest expense by approximately $0.1 million during the current quarter versus the same period last year.

Investment Expense (Income), Net Net investment income of $6.3 million during the third quarter of fiscal 2013 compares to net investment income of $2.2 million during the same period last year. Net realized gains and losses on the sales of investments totaled $2.9 million for the quarter ended February 28, 2013, and $0.2 million for the quarter ended February 29, 2012. Dividend and interest income totaled $3.4 million during the third quarter of fiscal 2013 versus $2.0 million during the same period a year ago. There were no impairments recognized on securities that management has determined are other-than-temporary declines in value during either period.

Other Expense (Income), Net Other expense of $4.7 million for the third quarter of fiscal 2013 compared with other income of approximately $1.4 million for the third quarter of fiscal 2012. Included in this amount was approximately $0.9 million and $0.4 million of royalty income for the third quarters of fiscal 2013 and fiscal 2012, respectively. Additionally, during the third quarter of fiscal 2013, we repositioned certain of our industrial segment operations in Brazil, which resulted in a substantial liquidation of certain of our Brazilian subsidiaries and a net loss of approximately $6.1 million. Also included is our equity in earnings of unconsolidated affiliates totaling approximately $0.5 million and $1.0 million for the third quarter of fiscal 2013 and 2012, respectively.

Income (Loss) Before Income Taxes (“IBT”) Our consolidated pretax loss for the third quarter of fiscal 2013 of $62.8 million compares with pretax income of $11.4 million for the third quarter of fiscal 2012.

Our industrial segment had a pretax loss of $68.6 million for the quarter ended February 28, 2013, versus pretax income of $20.4 million for the quarter ended February 29, 2012. The decline in IBT for the industrial segment resulted primarily from an adjustment for a $68.8 million accrual associated with an investigation of the RPM Building Solutions Group roofing contracts with the U.S. General Services Administration. The industrial segment also had foreign exchange losses incurred on cross-currency transactions and a loss incurred on the substantial liquidation of our repositioning of certain operations in Brazil. The net loss in Brazil included the impact of an adjustment for accumulated foreign currency translation, which was previously recorded as an unrealized foreign exchange loss in our currency translation account as a component of other comprehensive income. Our consumer segment IBT increased to $34.7 million, or 11.2% of net sales for the third quarter of fiscal 2013, from the comparable prior year period result of $21.5 million, or 7.9% of net sales. This was driven primarily by the 14.6% growth in net sales for the consumer segment in the third quarter of fiscal 2013 from the comparable prior year period.

Income Tax Rate The effective income tax rate was 32.8% for the three months ended February 28, 2013 compared to an effective income tax rate of 30.7% for the three months ended February 29, 2012.

For the three months ended February 28, 2013 and February 29, 2012, respectively, reductions to the effective tax rate related to lower effective tax rates of certain of our foreign subsidiaries, the favorable impact of certain foreign operations on our U.S. taxes, the research and development tax credit, and the benefit of the domestic manufacturing deduction. These decreases in the effective tax rates were offset by the net impact of valuation allowances associated with U.S. foreign tax credit carryforwards and certain foreign net operating losses, state and local income taxes, non-deductible business operating expenses, and due to net additions to our reserves for income tax contingencies, including interest thereon.

39

Furthermore, for the three month period ended February 28, 2013, the effective tax rate differed from the federal statutory rate as a result of income tax benefits related to the company’s strategic decision to reposition certain Brazilian business operations partially offset by 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 and by the tax effect of projected non-deductible costs associated with the DOJ and GSA accrual.

As of February 28, 2013, 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 February 28, 2013 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.

Net Income (Loss) Net loss of $42.2 million for the quarter ended February 28, 2013 compares to net income of $7.9 million for the quarter ended February 29, 2012, which results in a negative net margin on sales of 5.0% for the third quarter of fiscal 2013 and a positive margin on sales of 1.0% for the third quarter of fiscal 2012. The primary driver of the decline was the impact of an adjustment for a $68.8 million accrual associated with an investigation of the RPM Building Solutions Group roofing contracts with the U.S. General Services Administration. While organic sales volume grew by 1.9% during the third quarter of fiscal 2013 versus net sales for the third quarter of fiscal 2012, there was the impact of unfavorable foreign exchange, higher employee compensation, distribution and professional service expense during the third quarter of fiscal 2013 versus the comparable prior year period. During the quarter ended February 28, 2013, we had net income from noncontrolling interests of $0.2 million versus $1.3 million during the comparable prior year period. Net loss attributable to RPM International Inc. stockholders was $42.4 million for the quarter ended February 28, 2013, versus net income of $6.6 million for the quarter ended February 29, 2012.

Diluted loss per share of common stock for the quarter ended February 28, 2013 of $0.33 compares with diluted earnings per share of common stock of $0.05 for the quarter ended February 29, 2012.

Nine Months Ended February 28, 2013

Net Sales On a consolidated basis, net sales of $2.9 billion for the nine months ended February 28, 2013 improved 8.7%, or $232.3 million, over net sales of $2.7 billion during the same period last year. The organic growth in sales amounted to 1.5%, or $39.6 million, of the increase in the current period net sales versus net sales for the same period a year ago, which includes the impact of unfavorable foreign exchange rates year-over-year, which amounted to 1.3% of net sales for last year’s first nine months, or $35.4 million. These losses resulted primarily from the strong dollar against the euro, as well as versus the Latin American and Asia Pacific currencies. Nine acquisitions over the last twelve months provided 7.2% of net sales growth over last year’s first nine months, or $192.7 million.

Industrial segment net sales, which comprised 66% of consolidated net sales for this year’s first nine months, totaled $1.9 billion, an increase of 6.4% from $1.8 billion during last year’s first nine months. This increase in the industrial segment’s net sales reflects the favorable impact of six acquisitions completed over the last twelve months, which provided 6.5% of this segment’s current period growth in net sales versus net sales for the same period a year ago, offset partially by an organic decline of 0.1% of net sales for the prior year period. Reflected in the organic sales decline is unfavorable foreign exchange of 1.7%. Lastly, during the first quarter of fiscal 2013, this segment recorded a reversal of sales in relation to a loss contract outside of North America, as further described below under, “Gross Profit Margin.”

Consumer segment net sales, which comprised 34% of consolidated net sales for this year’s first nine months, totaled $981.1 million, an increase of 13.4% from $865.1 million during the same period a year ago. The

40

improvement in this segment resulted from organic growth in sales of 4.9%, which includes the impact of unfavorable foreign exchange, which amounted to 0.5% of the prior period net sales. Three acquisitions over the last twelve months had a favorable impact of approximately 8.5% on this segment’s net sales during this year’s first nine months versus the same period a year ago.

Gross Profit Margin Our consolidated gross profit margin improved to 41.4% of net sales for the first nine months of fiscal 2013 from 40.4% of net sales for the same period last year, reflecting our 1.5% growth in organic sales for the current period versus the same period last year. Slightly offsetting that favorable impact was the combination of unfavorable foreign exchange and the current period unfavorable mix of sales. Additionally, the current nine month period gross profit margin was negatively impacted by approximately 20 basis points as a result of one-time charges taken by the roofing division of RPM’s Building Solutions Group. The charges were taken during the first quarter of the current fiscal year for revised cost estimates in conjunction with unprofitable contracts outside of North America. The contract that led to these losses was a roofing project located at the Mumbai airport in India. The project began to incur cost overruns which, as the problem was realized and the extent of the losses were estimable, led to our recognition of large losses during the three months ended August 31, 2012. The total value of the related contract was approximately $16 million. In connection with the issues identified with this particular contract, we determined that it was appropriate to also terminate several individuals at its European business, and to also discontinue bidding on certain types of general contracting projects in North America which do not meet our current profit criteria. In relation to North America, we determined that it was appropriate to also terminate certain individuals associated with this area of the business. We do not anticipate any additional future losses in relation to the Mumbai airport project.

SG&A Our consolidated SG&A increased to 32.8% of net sales for the first nine months of fiscal 2013 compared with 31.1% of net sales for the same period a year ago. The 180 basis point increase in SG&A as a percent of net sales versus the prior year reflects the unfavorable impact of cross-currency transactions of approximately $6.4 million for the first nine months of fiscal 2013 over the benefit booked in the comparable prior year period. The increase in SG&A as a percent of net sales versus the prior period also reflects the impact of the $5.0 million bad debt write down recorded during this year’s first quarter in relation to our $10.0 million outstanding loan to Kemrock. Employee severance expense was approximately $6.8 million higher during the first nine months of fiscal 2013 than during the same period a year ago. Lastly, the increase in SG&A expense includes the impact of increased employee compensation-related expenses, including pension and postretirement benefit expense, increased advertising expense and outside professional services expense. Warranty expense for the nine months ended February 28, 2013 increased marginally from the amount recorded during the comparable prior year period. We anticipate that warranty expense will fluctuate from period to period, but will likely continue to slowly decline over the next few years.

Our industrial segment SG&A was approximately $77.2 million higher during the first nine months of fiscal 2013 versus the comparable prior year period, and higher as a percentage of net sales, reflecting the unfavorable impact of the $5.0 million bad debt write down on our loan to Kemrock recorded during this year’s first quarter. Additionally, the industrial segment’s roofing division recorded a $10.6 million loss during this year’s first quarter related to a loss contract outside North America and exit costs related to this contract as discussed above under “Gross Profit Margin.” The nature of the exit costs was a combination of severance costs for the individuals involved in the European roofing business and general contracting activity in North America and a reserve against certain receivables associated with the Mumbai airport project. Lastly, the industrial segment results for the first nine months of fiscal 2013 reflect the impact of higher employee compensation and benefit expense, increased employee severance expense, higher legal and distribution expense versus the comparable prior year period.

Our consumer segment SG&A was approximately $29.6 million higher during the first nine months of fiscal 2013 versus the comparable prior year period, and slightly higher as a percentage of net sales during the first nine months of fiscal 2013 as compared with the same period a year ago, primarily reflecting the impact of higher acquisition-related expense, legal and advertising expense during this year’s first nine months versus the same period a year ago.

41

SG&A expenses in our corporate/other category increased by $15.0 million during the first nine months of fiscal 2013 to $50.1 million from $35.1 million during the comparable prior year period. The increase in SG&A expense reflects the combination of higher employee compensation and pension benefit expenses and higher legal expense.

We recorded total net periodic pension and postretirement benefit costs of $38.8 million and $26.2 million for the first nine months of fiscal 2013 and fiscal 2012, respectively. The $12.6 million increase in pension expense was primarily the result of $7.0 million of additional net actuarial losses incurred during the first nine months of fiscal 2013 versus the comparable prior year period and a $5.0 million increase in service and interest cost during the first nine months of fiscal 2013 versus the comparable prior year period. A lower expected return on plan assets had an unfavorable impact on pension expense of approximately $0.6 million for the nine months ended February 28, 2013 versus the comparable prior year period. We expect that pension expense will fluctuate on a year-to-year basis, depending primarily upon the investment performance of plan assets and potential changes in interest rates, but such changes are not expected to be material to our consolidated financial results.

Estimated Loss Contingency During the quarter ended February 28, 2012, we recorded a $68.8 million accrual associated with settlement discussions that we are currently having with the DOJ and the GSA Office of Inspector General aimed at resolving an existing investigation. Refer to the section captioned “Three Months Ended February 28, 2013 — Estimated Loss Contingency,” for further information.

Interest Expense Interest expense was $58.8 million for the first nine months of fiscal 2013 versus $53.6 million for the same period a year ago. Higher average borrowings, related to recent acquisitions, increased interest expense during this year’s first nine months by approximately $8.5 million versus the same period a year ago. Excluding acquisition-related borrowings, lower average borrowings year-over-year decreased interest expense by approximately $1.7 million. Lower interest rates, which averaged 5.27% overall for the first nine months of fiscal 2013 compared with 6.21% for the same period of fiscal 2012, decreased interest expense by approximately $1.6 million during the current nine-month period versus the same period last year.

Investment Expense (Income), Net Net investment income of $14.6 million during this year’s first nine months compares to net investment income of $3.3 million for the same period a year ago. Dividend and interest income totaled $7.7 million during this year’s first nine months versus $4.7 million of income during the same period last year. Net realized gains on the sales of investments resulted in a net gain of $7.5 million for this year’s first nine months versus a net loss of $0.7 million for the same period during fiscal 2012. Impairments recognized on securities that management has determined are other-than-temporary declines in value approximated $0.6 million for the first nine months of fiscal 2013, versus impairments of $0.7 million for the same period a year ago.

Other (Income), Net Other expense for this year’s first nine months of $53.8 million compares with other income of $8.4 million during the same period a year ago. The majority of other expense for this year’s first nine months, approximately $46.4 million, was recorded by our corporate/other segment, and represents the impairment loss recorded in relation to our investment in Kemrock. As previously discussed, we increased our ownership in Kemrock to over 20% of Kemrock’s outstanding shares of common stock during fiscal 2012. Additionally, we agreed to loan them funds and made additional investments in Kemrock throughout fiscal 2012, and at May 31, 2012, the carrying value of our investment in Kemrock totaled $42.2 million. On August 8, 2012, the price of Kemrock’s common stock plunged below our carrying value, declining by approximately 40% from May 31, 2012. We later learned that the dramatic drop in Kemrock’s stock price was related to Kemrock’s announcement of declining sales and income, a liquidity problem at Kemrock that stemmed from its explosive growth, combined with an overall tightening of the lending practices of the banks and credit markets in India. At that time, we learned that Kemrock was in the process of renegotiating its credit agreements with its banks. Compounding these difficulties for Kemrock was the deterioration in the exchange rate of the Indian rupee against the U.S. dollar and Euro, which had a negative impact on Kemrock’s gross profit margins and cash flow due to its procurement of the majority of its raw material supplies outside of India, but sales of its products in

42

Indian Rupees. Additionally, the market value of shares of Kemrock common stock have steadily declined, and as a result of the combination of these factors, we determined that it was appropriate to record an impairment loss on our investment during the current fiscal year totaling $51.1 million on a consolidated basis.

The majority of the remaining balance in other expense (income) is recorded by our industrial segment. During the third quarter of fiscal 2013, we repositioned certain industrial segment operations in Brazil, which resulted in a substantial liquidation of certain of our Brazilian subsidiaries and a net loss of approximately $6.1 million. Lastly, other expense (income) includes royalty income of approximately $1.6 million and $1.2 million for the first nine months of fiscal 2013 and fiscal 2012, respectively, and our equity in earnings of unconsolidated affiliates totaling approximately $1.8 million and $3.3 million for the first nine months of fiscal 2013 and fiscal 2012, respectively.

IBT Our consolidated pretax income for this year’s first nine months of $80.3 million compares with pretax income of $206.3 million for the same period last year, resulting in a pretax profit margin on net sales of 2.8% for the current period versus a pretax profit margin on net sales of 7.7% a year ago.

Our industrial segment had IBT of $81.2 million, for a profit margin on net sales of 4.2% for this year’s first nine months versus IBT of $189.2 million, for a profit margin on net sales of 10.4%, for the same period last year. The decline reflects the impact of the adjustment for a $68.8 million accrual associated with an investigation of the RPM Building Solutions Group roofing contracts with the U.S. General Services Administration. Our consumer segment IBT increased to $132.1 million, or 13.5% of net sales for the period, from last year’s first nine months’ IBT of $99.8 million, or 11.5% of net sales. The increase in IBT as a percent of sales for the consumer segment resulted primarily from the impact of the 4.9% growth in organic sales combined with the impact of favorable acquisitions during the current period versus the same period a year ago.

Income Tax Rate The effective income tax rate was 48.0% for the nine months ended February 28, 2013 compared to an effective income tax rate of 29.6% for same period a year ago.

For the nine months ended February 28, 2013 and February 29, 2012, 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 research and development tax credit, and the benefit of the domestic manufacturing deduction. Additionally, the effective tax rate for both periods decreased as a result of a reduction in the United Kingdom income tax rate. Further, the effective income tax rate for the nine months ended February 29, 2012 decreased due to net reductions to our reserves for income tax contingencies, including interest thereon.

These decreases in the effective tax rate were offset by the net 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 nine month period ended February 28, 2013, the effective tax rate differed from the federal statutory rate as a result of income tax benefits related to the company’s strategic decision to reposition certain Brazilian business operations, offset by 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, by the tax effect of projected non-deductible costs associated with the DOJ and GSA accrual and due to net increases to our reserves for income tax contingencies, including interest thereon. Additionally, for the nine months ended February 28, 2013 the effective tax rate differed from the federal statutory rate as a result of increases in valuation allowances related to losses associated with our investments in Kemrock.

As described in this Management’s Discussion and Analysis of Financial Condition and Results of Operations for the three month period ended February 28, 2013, there is uncertainty as to whether we will be able to recognize certain deferred tax assets. Refer to the section captioned “Three Months Ended February 28, 2013 — Income Tax Rate,” for further information.

43

Net Income Net income of $41.8 million for the first nine months of fiscal 2013 compares to net income of $145.2 million for the same period last year, or a decline of $103.4 million period-over-period, principally due to an adjustment for a $68.8 million accrual associated with an investigation of the RPM Building Solutions Group roofing contracts with the U.S. General Services Administration. The decline also reflects the losses we recorded on our various investments in Kemrock, totaling $51.1 million after-tax. This results in a net margin on sales of 1.4% and 5.4% for the nine month periods ended February 28, 2013 and February 29, 2012, respectively. While organic sales grew by 1.5% during the current period versus net sales for the same period last year, employee compensation, distribution and acquisition-related expenses were higher during the current period versus the same period a year ago. During the nine months ended February 28, 2013, we had net income from noncontrolling interests of $8.6 million versus $11.8 million during the same period a year ago. Net income attributable to RPM International Inc. stockholders was $33.2 million for the nine months ended February 28, 2013, versus $133.4 million for the same period a year ago, for a margin on net sales of 1.1% and 5.0% for the first nine months of fiscal 2013 and 2012, respectively.

Diluted earnings per share of common stock for the first nine months of fiscal 2013 of $0.25 compares with $1.02 for the same period last year.

LIQUIDITY AND CAPITAL RESOURCES

Operating Activities

Operating activities provided cash flow of $170.9 million for the nine months ended February 28, 2013 compared with $153.5 million during the prior fiscal year period, resulting in a net increase in cash of $17.4 million during the first nine months of fiscal 2013 versus fiscal 2012.

The net change in cash from operations includes the change in net income, which decreased by $103.4 million during the first nine months of fiscal 2013 versus the same period during fiscal 2012. Reflected in net income for the nine months ended February 28, 2013 are $112.7 million of one-time charges. The non-cash charges include an after-tax charge of $52.6 million resulting from our estimated accrual for a loss contingency; an after-tax charge of $53.3 million in write downs associated with our various investments in Kemrock; and an after-tax charge of approximately $8.4 million associated with a combination of revised cost estimates in conjunction with loss contracts in our industrial segment’s roofing division and exit costs related to those contracts. Other items impacting the net change in cash from operations included items adjusting net income for non-cash expenses and income, which increased cash flows by approximately $126.5 million more during the current fiscal year period versus the prior fiscal year period; and changes in working capital accounts and all other accruals, which increased cash flows by $5.7 million during the current fiscal year period versus the prior fiscal year period.

The decrease in accounts receivable since May 31, 2012 represents the generation of $137.1 million in cash during the current period versus the $128.4 million of cash generated by accounts receivable during the first nine months of fiscal 2012, or approximately $8.7 million more cash generated year-over-year. This resulted from the timing of sales and collections on accounts receivable. Days sales outstanding at February 28, 2013 decreased slightly to 64.9 days from 67.9 days sales outstanding at February 29, 2012.

Inventory balances used $73.3 million of cash during the first nine months of fiscal 2013, compared with a use of cash of $25.4 million during the first nine months of fiscal 2013, or $47.9 million more cash used year-over-year. Days of inventory outstanding at February 28, 2013 decreased slightly to 105.4 days from 98.9 days of inventory outstanding at February 29, 2012.

The current year-to-date change in accounts payable used $3.2 million less cash during the current period compared to the same period a year ago, resulting from a change in the timing of certain payments during the current period versus the same period a year ago. Accrued compensation and benefits used approximately $11.5 million more cash during the first nine months of fiscal 2013 versus the same period during the prior fiscal

44

year, as there were higher bonus payments made during the current year versus the same period a year ago. Other accruals and prepaids, including those for other short-term and long-term items and changes, provided $43.2 million more cash during the first nine months of fiscal 2013 versus the first quarter of the prior fiscal year, due to changes in the timing of such payments.

Cash provided from operations, along with the use of available credit lines, as required, remain our primary sources of liquidity.

Investing Activities

Capital expenditures, other than for ordinary repairs and replacements, are made to accommodate our continued growth to achieve production and distribution efficiencies, expand capacity, introduce new technology, improve environmental health and safety capabilities, improve information systems, and enhance our administration capabilities. Capital expenditures of $45.7 million during the first nine months of fiscal 2013 compare with depreciation of $41.9 million. Our capital spending levels currently exceed depreciation expense, and we expect that trend to continue for the remainder of fiscal 2013. We believe our current production capacity, along with moderate plant modifications or additions will be adequate to meet our immediate needs based on anticipated growth rates. Not reflected in our capital expenditures is the capacity added through our recent acquisitions of product lines and businesses, which totaled approximately $46.3 million during fiscal 2013. We anticipate that additional shifts at our production facilities, coupled with the capacity added through acquisition activity and our planned increase in future capital spending levels, will enable us to meet increased demand during the current fiscal year.

Our captive insurance companies invest their excess cash in marketable securities in the ordinary course of conducting their operations, and this activity will continue. Differences in the amounts related to these activities on a year-over-year basis are primarily attributable to differences in the timing and performance of their investments balanced against amounts required to satisfy claims. At February 28, 2013, the fair value of our investments in marketable securities totaled $117.7 million, of which investments with a fair value of $45.7 million were in an unrealized loss position. Included in the $117.7 million of marketable securities, but held outside of our captive insurers, is our $11.6 million investment in 5.5% convertible bonds issued by Kemrock in April 2012. 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. The fair value of our portfolio of marketable securities is based on quoted market prices for identical, or similar, instruments in active or non-active markets or model-derived-valuations with observable inputs. We have no marketable securities whose fair value is subject to unobservable inputs. At May 31, 2012, the fair value of our investments in marketable securities totaled $120.1 million, of which investments with a fair value of $43.8 million were in an unrealized loss position. Total pretax unrealized losses recorded in accumulated other comprehensive income at February 28, 2013 and May 31, 2012 were $3.6 million and $3.1 million, respectively.

We regularly review our marketable securities in unrealized loss positions in order to determine whether or not we have the ability and intent to hold these investments. That determination is based upon the severity and duration of the decline, in addition to our evaluation of the cash flow requirements of our businesses. Unrealized losses at May 31, 2012 were generally related to the normal volatility in valuations over the past several months for a portion of our portfolio of investments in marketable securities. The unrealized losses generally relate to investments whose fair values at May 31, 2012 were less than 15% below their original cost or that have been in a loss position for less than nine consecutive months. 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.

45

As of February 28, 2013, approximately 83% of our consolidated cash and cash equivalents were held at various foreign subsidiaries. Currently, the funds held at our foreign subsidiaries are considered permanently reinvested to be used, for instance, to expand operations organically or for acquisitions in foreign jurisdictions. Our operations in the U.S. generate sufficient cash flow to satisfy U.S. operating requirements. Although we do not intend to repatriate any significant amounts of these cash balances to the U.S. in the foreseeable future, any repatriation of these balances could be subject to governmental restrictions and U.S. and foreign taxes. However, a portion of the foreign earnings have previously been subject to U.S. taxation and could be repatriated to the U.S. with little or no residual tax impact. We believe that the tax impact of repatriating these previously taxed earnings to the U.S. would not have a material impact on our financial results.

As previously stated, we intend to permanently reinvest the cash and cash equivalents held at our various foreign subsidiaries for foreign expansion and other uses. Due to the uncertainties and complexities involved in the various options for repatriation of foreign cash, including any associated governmental or other restrictions, it is not practicable to calculate the deferred taxes associated with the remittance of these cash balances.

Financing Activities

As a result of the SPHC bankruptcy filing, our access to the cash flows of SPHC and its subsidiaries has been restricted. However, the bankruptcy filing has not resulted in any reductions in our credit ratings by Moody’s Investor Service, Standard & Poors or Fitch Ratings. Therefore, we feel this has not adversely impacted our ability to gain access to capital.

The following table summarizes our financial obligations and their expected maturities at February 28, 2013 and the effect such obligations are expected to have on our liquidity and cash flow in the periods indicated.

Contractual Obligations

	Total Contractual Payment Stream		Payments Due In
			2014		2015-16		2017-18		After 2018
	(In thousands)
Long-term debt obligations	$	1,395,938	$	1,218	$	24,698	$	609,277	$	760,745
Capital lease obligations		1,858		623		1,128		107
Operating lease obligations		179,077		42,252		58,097		34,158		44,570
Other long-term liabilities (1):
Interest payments on long-term debt obligations		417,838		75,164		125,672		108,325		108,677
Contributions to pension and postretirement plans (2)		359,800		34,000		89,000		91,500		145,300
Total	$	2,354,511	$	153,257	$	298,595	$	843,367	$	1,059,292

(1) Excluded from other long-term liabilities are our gross long-term liabilities for unrecognized tax benefits, which totaled $12.7 million at February 28, 2013. Currently, we cannot predict with reasonable reliability the timing of cash settlements to the respective taxing authorities related to these liabilities.

(2) These amounts represent our estimated cash contributions to be made in the periods indicated for our pension and postretirement plans, assuming no actuarial gains or losses, assumption changes or plan changes occur in any period. The projection results assume the required minimum contribution will be contributed.

46

Off-Balance Sheet Arrangements

We do not have any off-balance sheet financings, other than the minimum operating lease commitments included in the above Contractual Obligations table. We have no subsidiaries that are not included in our financial statements, nor do we have any interests in, or relationships with, any special purpose entities that are not reflected in our financial statements. At the end of fiscal 2010, we deconsolidated our wholly owned subsidiary, SPHC, and its subsidiaries, from our balance sheet and eliminated the results of SPHC’s operations from our operations beginning on May 31, 2010. We account for our investment in SPHC, which had no value at February 28, 2013 and May 31, 2012, under the cost method (refer to Note 3 to the Consolidated Financial Statements).

OTHER MATTERS

Environmental Matters

Environmental obligations continue to be appropriately addressed and, based upon the latest available information, it is not anticipated that the outcome of such matters will materially affect our results of operations or financial condition. Our critical accounting policies and estimates set forth above describe our method of establishing and adjusting environmental-related accruals and should be read in conjunction with this disclosure. For additional information, refer to “Part II, Item 1. Legal Proceedings.”

FORWARD-LOOKING STATEMENTS

The foregoing discussion includes forward-looking statements relating to our business. These forward-looking statements, or other statements made by us, are made based on our expectations and beliefs concerning future events impacting us and are subject to uncertainties and factors (including those specified below), which are difficult to predict and, in many instances, are beyond our control. As a result, our actual results could differ materially from those expressed in or implied by any such forward-looking statements. These uncertainties and factors include (a) global markets and general economic conditions, including uncertainties surrounding the volatility in financial markets, the availability of capital and the effect of changes in interest rates, and the viability of banks and other financial institutions; (b) the prices, supply and capacity of raw materials, including assorted pigments, resins, solvents, and other natural gas- and oil-based materials; packaging, including plastic containers; and transportation services, including fuel surcharges; (c) continued growth in demand for our products; (d) legal, environmental and litigation risks inherent in our construction and chemicals businesses and risks related to the adequacy of our insurance coverage for such matters; (e) the effect of changes in interest rates; (f) the effect of fluctuations in currency exchange rates upon our foreign operations; (g) the effect of non-currency risks of investing in and conducting operations in foreign countries, including those relating to domestic and international political, social, economic and regulatory factors; (h) risks and uncertainties associated with our ongoing acquisition and divestiture activities; (i) risks related to the adequacy of our contingent liability reserves; (j) risks and uncertainties associated with the SPHC bankruptcy proceedings; and (k) other risks detailed in our filings with the Securities and Exchange Commission, including the risk factors set forth in our Annual Report on Form 10-K for the year ended May 31, 2012, as the same may be updated from time to time. We do not undertake any obligation to publicly update or revise any forward-looking statements to reflect future events, information or circumstances that arise after the filing date of this document.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk from changes in raw materials costs, interest rates and foreign exchange rates since we fund our operations through long- and short-term borrowings and conduct our business in a variety of foreign currencies. There were no material potential changes in our exposure to these market risks since May 31, 2012.

47

ITEM 4. CONTROLS AND PROCEDURES

(a) EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES.

Our Chief Executive Officer and Chief Financial Officer, after evaluating the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) as of February 28, 2013 (the “Evaluation Date”), have concluded that as of the Evaluation Date, our disclosure controls and procedures were effective in ensuring that information required to be disclosed by us in the reports we file or submit under the Exchange Act (1) is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms, and (2) is accumulated and communicated to our management, including the Chief Executive Officer and the Chief Financial Officer, as appropriate to allow for timely decisions regarding required disclosure.

(b) CHANGES IN INTERNAL CONTROL.

There were no changes in our internal control over financial reporting that occurred during the fiscal quarter ended February 28, 2013 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

48

PART II — OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Asbestos Litigation and the Bankruptcy Filings by SPHC and Bondex

For information regarding asbestos litigation involving SPHC and Bondex, see Note 3 to the Consolidated Financial Statements. On May 31, 2010, Bondex and its parent, SPHC, filed voluntary petitions in the United States Bankruptcy Court for the District of Delaware to reorganize under Chapter 11 of the Bankruptcy Code.

Environmental Proceedings

As previously reported, several of our subsidiaries are, from time to time, identified as a “potentially responsible party” under the Federal Comprehensive Environmental Response, Compensation and Liability Act and similar state environmental statutes. In some cases, our subsidiaries are participating in the cost of certain clean-up efforts or other remedial actions. Our share of such costs, however, has not been material and we believe that these environmental proceedings will not have a material adverse effect on our consolidated financial condition or results of operations. See “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Other Matters,” in Part I of this Quarterly Report on Form 10-Q.

ITEM 1A. RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the risk factors disclosed in Item 1A of our Annual Report on Form 10-K for the fiscal year ended May 31, 2012.

ITEM 2. UNREGISTERED SALE OF EQUITY SECURITIES AND USE OF PROCEEDS

Earnings Per Share (Tables)

Reconciliation of Numerator and Denominator of Basic and Diluted Earnings Per Share Calculated using Two-Class Method

The following table sets forth the reconciliation of the numerator and denominator of basic and diluted earnings per share, as calculated using the two-class method, for the nine months ended February 28, 2013 and February 29, 2012. For the three month periods ended February 28, 2013 and February 29, 2012, the treasury stock method was utilized for the purpose of computing basic and diluted earnings per share, as the result under the two-class method would have been anti-dilutive.

	Three Months Ended					Nine Months Ended
(In thousands, except per share amounts)	February 28, 2013			February 29, 2012		February 28, 2013			February 29, 2012

Diluted Earnings Per Share of Common Stock	$	(0.33	)	$	0.05	$	0.25		$	1.02

Deconsolidation of Specialty Products Holding Corp. ("SPHC")

9 Months Ended

Deconsolidation of Specialty Products Holding Corp. ("SPHC")

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 therefore deconsolidated SPHC and its subsidiaries from our balance sheet as of May 31, 2010, and 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 during our 2013 third fiscal quarter, a provision for the remaining appeal bond was accrued and payment will be made during our 2013 fourth fiscal quarter. 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 February 28, 2013.

Investment in Kemrock Industries and Exports Ltd.

9 Months Ended

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 accounted for as an available-for-sale security and is classified in other long-term assets in our Consolidated Balance Sheet. The convertible feature embedded in the convertible bonds is accounted for as a derivative under the guidance in ASC 815, “Derivatives and Hedging.”

At the time of our investment in Kemrock’s convertible bonds, Kemrock was in the midst of major capital expansion for new projects and upcoming technologies, and there were no indications of any adverse business, economic, competitive, or market factors. However, on August 8, 2012, the price of Kemrock’s common stock plunged below our carrying value, declining by approximately 40% from May 31, 2012. We later learned that the dramatic drop in Kemrock’s stock price was related to Kemrock’s announcement of declining sales and income, a liquidity problem at Kemrock that stemmed from its explosive growth, combined with the overall tightening of lending practices of banks and credit markets in India. At that time, we also learned that Kemrock was in the process of renegotiating its credit agreements with its banks. Compounding these difficulties for Kemrock was the deterioration in the exchange rate of the Indian rupee against the U.S. dollar and Euro, which had a negative impact on Kemrock’s gross profit margin and cash flow due to its procurement of the majority of its raw material supplies outside of India, but sales of its products in Indian rupees. The market value of shares of Kemrock common stock continued to decline significantly, and dropped from 531.0 rupees per share as of May 31, 2012 to 56.70 rupees per share as of November 30, 2012 and 52.90 rupees per share as of February 28, 2013. The majority of the decline in the market value of Kemrock shares began to occur during the month of August 2012.

We account for our equity method investment in Kemrock under ASC 323, “Investments – Equity Method and Joint Ventures.” As outlined in ASC 323-10-35-32, a decline in the quoted market price below the carrying amount when combined with other evidence of a loss in value may be indicative of a loss in value that is other than temporary. Acting upon the premise that a write-down may be required, we considered all available evidence to evaluate the realizable value of our equity investment, including the decline in the market price of shares of Kemrock stock, the financial condition and near term prospects of Kemrock, and the overall economic situation in India. As a result of these factors, we determined that it was appropriate to record an impairment loss during the three months ended August 31, 2012 of approximately $32.1 million of our equity method investment. As the value of the embedded conversion derivative is directly correlated to the market value of Kemrock stock, we wrote-down the embedded conversion feature derivative and recorded an approximate $8.2 million charge to earnings during the three months ended August 31, 2012.

After further monitoring of the economic environment in India and the continued declines in the price of Kemrock common stock during the three months ended November 30, 2012, we determined that it was appropriate to write off the remaining value of the convertible feature embedded in our investment in Kemrock convertible bonds, approximating $0.8 million, and the remaining equity investment in Kemrock, approximating $10.1 million, which represented our proportionate share of Kemrock losses under the equity method of accounting and the significant decline in the price of Kemrock stock during that time frame. The losses are classified in other (income) expense, net in our Consolidated Statements of Income. Please see Note 11, for additional information.

As of February 28, 2013, Kemrock had repaid approximately $5.4 million of the original $15.0 million loan. We anticipate that we will receive approximately $4.6 million in goods and materials by the end of the current fiscal year, and therefore previously 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.

Stock Repurchase Program

Stock Repurchase Program

NOTE 16 — 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 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 February 28, 2013, we did not repurchase any shares of our common stock under this program.

Recently Completed Acquisitions

NOTE 18 — RECENTLY COMPLETED ACQUISITIONS

On September 5, 2012, we acquired Kirker Enterprises, Inc., a leading manufacturer of nail care enamels, coatings components and related products for the personal care industry. Based in Paterson, New Jersey, Kirker has annual sales in excess of $100 million. Kirker will be managed and reported by our RPM2 — Consumer operating segment.

On September 21, 2012, we acquired Synta, Inc., a producer and marketer of innovative and unique exterior wood deck and concrete restoration systems sold through leading national home centers and marketed under the brands of Deck Restore and Concrete Restore. Synta’s products also include a craft coatings line. Based in Clarkston, Georgia, Synta has annualized sales expected to exceed $40 million. Synta will be managed and reported by our Rust-Oleum operating segment.

The preliminary fair value of acquired goodwill and other intangible assets for the two acquisitions described above totaled approximated $160.9 million and $103.3 million, respectively. Additionally, the preliminary fair value of contingent consideration for these two acquisitions combined totaled approximately $63.5 million. Opening balance sheet valuations for these two recent acquisitions are ongoing. A final determination of the purchase price allocation will be made based upon the completion of the determination of the fair value of acquired tangible and intangible assets and our assessment of deferred income taxes.

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 nine-month periods ended February 28, 2013 and February 29, 2012. 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.

During the third quarter of fiscal 2013, we recorded an adjustment to our current loss reserves to remove the impact of claims that we have determined will not likely be paid out over the next 12 months, which should have been included in the long-term accrued loss reserves as of May 31, 2012. As a result, long-term accrued loss reserves (a component of other long-term liabilities) were increased by $25.8 million, and current accrued loss reserves were decreased by an equal amount, in order to reflect this reclassification as of May 31, 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. 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 convertible bonds is accounted for as an available-for-sale security and is classified in other long-term assets in our Consolidated Balance Sheet. The convertible feature embedded in the convertible bonds is accounted for as a derivative under the guidance in ASC 815, “Derivatives and Hedging.”

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.

We account for our equity method investment in Kemrock under ASC 323, “Investments – Equity Method and Joint Ventures.” As outlined in ASC 323-10-35-32, a decline in the quoted market price below the carrying amount when combined with other evidence of a loss in value may be indicative of a loss in value that is other than temporary. Acting upon the premise that a write-down of our investment in Kemrock may be required, we considered all available evidence to evaluate the realizable value of our equity investment, including a decline in the market price of shares of Kemrock stock, the financial condition and near term prospects of Kemrock, and the overall economic situation in India. As a result of these factors, we determined that it was appropriate to record an impairment loss during first half of fiscal 2013 of approximately $42.2 million on our equity method investment and a loss of approximately $9.0 million for the write-down of the embedded conversion derivative associated with our investment in Kemrock convertible bonds. The loss is classified in other (income) expense, net in our Consolidated Statements of Income. Please refer to 2, where information related to this investment is more fully described.

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 February 28, 2013 and a carrying value of $42.2 million at May 31, 2012.

Loss on Repositioning of Operations in Brazil

During the third quarter of fiscal 2013, we repositioned certain of our industrial segment operations in Brazil, resulting in a substantial liquidation of a subsidiary and a loss of approximately $6.1 million. Included in the loss was the write-off of the associated accumulated foreign currency translation. This non-cash charge was previously recorded as an unrealized foreign exchange loss in our currency translation account as a component of other comprehensive income.

Income Taxes

Income Taxes

NOTE 12 — INCOME TAXES

The effective income tax rate was 32.8% for the three months ended February 28, 2013 compared to an effective income tax rate of 30.7% for the three months ended February 29, 2012. The effective income tax rate was 48.0% for the nine months ended February 28, 2013 compared to an effective income tax rate of 29.6% for the same period a year ago.

For the three and nine months ended February 28, 2013 and February 29, 2012, 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 research and development tax credit, and due to the benefit of the domestic manufacturing deduction. Additionally, for the nine months ended February 28, 2013 and February 29, 2012, decreases in the effective income tax rate resulted from a reduction in the United Kingdom income tax rate. Further, the effective income tax rate for the nine months ended February 29, 2012 decreased due to net reductions to our reserves for income tax contingencies, including interest thereon.

For the three and nine months ended February 28, 2013 and February 29, 2012, 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 nine month periods ended February 28, 2013, the effective tax rate differed from the federal statutory rate as a result of income tax benefits related to our strategic decision to reposition certain Brazilian business operations, 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, the tax effect of projected non-deductible costs associated with the DOJ and GSA accrual and due to net increases to our reserves for income tax contingencies, including interest thereon. Additionally, for the nine months ended February 28, 2013 the effective tax rate differed from the federal statutory rate as a result of increases in valuation allowances related to losses associated with our investments in Kemrock.

As of February 28, 2013, we had unrecognized tax benefits of approximately $8.8 million, of which approximately $8.0 million would impact the effective tax rate, if recognized. We recognize interest and penalties related to unrecognized tax benefits in income tax expense. At February 28, 2013 the accrual for interest and penalties was $5.5 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 $2.2 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 February 28, 2013 we are subject to U.S. federal income tax examinations for the fiscal years 2011 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 2006 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 return for the fiscal 2011 tax year. Although it is possible that certain tax examinations could be resolved during the next 12 months, the timing and outcomes are uncertain.

During the third quarter of fiscal 2013 we settled the IRS examination of the company’s U.S. income tax returns for the fiscal 2009 and 2010 tax years resulting in a net refund. The IRS adjustments related to, amongst other items, the deductibility of certain of our expenditures, exclusion of selective items of miscellaneous income and our research tax credit positions. The settlement did not have a material impact on our financial statements.

As of February 28, 2013, 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 February 28, 2013 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.

Marketable securities, included in other current and long-term assets, totaling $106.1 million and $11.6 million at February 28, 2013, respectively, and $106.5 million and $13.6 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 the decline in the market value of the bond, and is classified in other long-term assets in our Consolidated Balance Sheet.

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 $3.1 million and $0.2 million, respectively, for the quarter ended February 28, 2013. Gross gains and losses realized on sales of investments were $0.3 million and $0.1 million, respectively, for the quarter ended February 29, 2012. During the third quarter of fiscal 2012, we recognized losses of approximately $0.1 million for securities deemed to have other-than-temporary impairments, while there were no similar losses recognized during the third quarter of fiscal 2013. 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 $8.1 million and $0.6 million, respectively, for the nine months ended February 28, 2013. Gross gains and losses realized on sales of investments were $4.1 million and $4.8 million, respectively, for the nine months ended February 29, 2012. During the first nine months of fiscal 2013 and 2012, we recognized losses of $0.6 million and $0.8 million, respectively, for securities deemed to have other-than-temporary impairments.

Summarized below are the securities we held at February 28, 2013 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:

	February 28, 2013					May 31, 2012
(In thousands)	Fair Value		Gross Unrealized Losses			Fair Value		Gross Unrealized Losses
Total investments with unrealized losses	$	45,700	$	(3,562	)	$	43,772	$	(3,078	)
Unrealized losses with a loss position for less than 12 months		44,848		(3,357	)		42,114		(2,596	)
Unrealized losses with a loss position for more than 12 months		852		(205	)		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 February 28, 2013 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 February 28, 2013 were less than 15% below their original cost or have been in a loss position for less than six consecutive months. Although we have seen 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 February 28, 2013, 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.

We previously disclosed in our financial statements for the fiscal year ended May 31, 2012 that we expected to contribute approximately $29.9 million to our retirement plans in the U.S. and approximately $8.3 million to plans outside the U.S. during the current fiscal year. In our financial statements for the quarterly period ended November 30, 2012, we disclosed that we expected to contribute $5.4 million less to our retirement plans in the U.S., for a total of $24.5 million. As of February 28, 2013, this has not changed.

Contingencies and Other Accrued Losses

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. Product liability reserves 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. While it is reasonably possible that excess liabilities, if they were to occur, could be material to operating results in any given quarter or year of their recognition, we do not believe that it is reasonably possible that excess liabilities would have a material adverse effect on our long-term results of operations, liquidity or consolidated financial position.

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 February 28, 2013, 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:

	Three Months Ended						Nine Months Ended

(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.

As of February 28, 2013, based on discussions that occurred on March 29, 2013, we recorded a $68.8 million accrual associated with an investigation of our Building Solutions Group roofing contracts with the U.S. General Services Administration (the “GSA”). The substantial majority of the accrual relates to the sale of products and services from 2002 to 2008. Our Building Solutions Group is in ongoing settlement 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 Building Solutions Group roofing division sold products and services to the federal government. The accrual for this contingency represents our assessment 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. The actual amount of our loss, which remains subject to approval by the DOJ, may vary from the amount of the accrual. 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 February 28, 2013.

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 collectability 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 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 $10.9 million at February 28, 2013, 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 first half of fiscal 2013, we recognized a loss of approximately $9.0 million, 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 February 28, 2013 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 February 28, 2013 and May 31, 2012 are as follows:

	At February 28, 2013

Reorganization Proceedings of Certain Subsidiaries

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 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 are seeking to formulate a consensual plan of reorganization pursuant to Section 524(g) of the Bankruptcy Code. That plan of reorganization would establish a trust to compensate present and future asbestos-related claims at appropriate values set forth in the trust documents and approved by the bankruptcy court, and would also provide for the imposition of a channeling injunction that would direct all future SPHC-related and Bondex-related asbestos claims to the trust.

In January 2013, a trial to estimate the aggregate current and future asbestos liabilities of the filing entities was conducted before Judge Judith K. Fitzgerald in the United States Bankruptcy Court for the District of Delaware. Closing arguments were held on March 4, 2013, and the judge is expected to render an opinion by the end of May 2013. That opinion will be subject to appeal by any of the parties. At this time, it is not possible to predict how the judge will rule, the outcome of any appeal, how long the Chapter 11 proceedings will last, or the form of any ultimate resolution of the Chapter 11 proceedings.

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.

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 six 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 six 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.

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 primarily 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.

New Accounting Pronouncements

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. 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.

In February 2013, the FASB further amended the disclosure requirements for comprehensive income. The update requires companies to disclose items reclassified out of AOCI and into net income in a single location either in the notes to the consolidated financial statements or parenthetically on the face of the Statements of Operations. The change is effective for fiscal years, and interim periods within those years, beginning after December 15, 2012, and is to be applied prospectively. We will adopt these provisions on June 1, 2013, and do not expect the adoption of these updated disclosure requirements to affect our consolidated results of operations, financial condition or liquidity.

Earnings Per Share

NOTE 14 — EARNINGS PER SHARE

The following table sets forth the reconciliation of the numerator and denominator of basic and diluted earnings per share, as calculated using the two-class method, for the nine months ended February 28, 2013 and February 29, 2012. For the three month periods ended February 28, 2013 and February 29, 2012, the treasury stock method was utilized for the purpose of computing basic and diluted earnings per share, as the result under the two-class method would have been anti-dilutive.

(1) For the three month period ended February 28, 2013, basic weighted-average shares outstanding are used in calculating diluted earnings per share as a result of the reported loss for the period. For the three month period ended February 29, 2012, approximately 2,811,000 shares of stock granted under stock-based compensation plans were excluded from the calculation of diluted EPS, as the effect would have been anti-dilutive.

(2) For the nine month periods ended February 28, 2013 and February 29, 2012, approximately 3,063,000 shares and 2,618,000 shares of stock, respectively, granted under stock-based compensation plans were excluded from the calculation of diluted EPS for those periods, as the effect would have been anti-dilutive.
