In planning and performing our audit, we considered the EPA's internal control over the Pesticide Registration Improvement Act (PRIA) financial reporting by obtaining an understanding of the agency's internal controls, determining whether internal controls had been placed in operation, assessing control risk, and performing tests of controls. We did this as a basis for designing our auditing procedures for the purpose of expressing an opinion on the financial statements and to comply with OMB audit guidance, not to express an opinion on internal control. Accordingly, we do not express an opinion on internal control over financial reporting or on management's assertion on internal controls included in Management's Discussion and Analysis. We limited our internal control testing to those controls necessary to achieve the objectives described in OMB Bulletin No. 07-04, Audit Requirements for Federal Financial Statements, as Amended. We did not test all internal controls relevant to operating objectives as broadly defined by the Federal Managers' Financial Integrity Act (FMFIA) of 1982, such as those controls relevant to ensuring efficient operations.
