Report of Independent Registered Public Accounting Firm
TO THE BOARD OF DIRECTORS AND STOCKHOLDERS
RPM International Inc. and Subsidiaries
Medina, Ohio
We have audited the accompanying consolidated balance sheets of RPM International Inc. and Subsidiaries (“RPM” or “the
Company”) as of May 31, 2011 and 2010 and the related consolidated statements of income, stockholders’ equity and cash flows
for each of the three years in the period ended May 31, 2011. These financial statements are the responsibility of the Company’s
management. Our responsibility is to express an opinion on these financial statements based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures
in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable
basis for our opinion.
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated
financial position of RPM at May 31, 2011 and 2010 and the consolidated results of their operations and their cash flows for each of
the three years in the period ended May 31, 2011, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the
effectiveness of RPM’s internal control over financial reporting as of May 31, 2011, based on criteria established in Internal Control-
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated
July 27, 2011 expressed an unqualified opinion thereon.
