On January 30, 2009, the SEC issued a release adopting final rules, "Interactive Data to Improve Financial Reporting" (SEC rules), that require issuers to provide their financial statements to the SEC and on their corporate Web sites in interactive data format using eXtensible Business Reporting Language (XBRL-tagged data). Today, the AICPA Auditing Standards Board has issued Statement of Position 09-1, Performing Agreed-Upon Procedures Engagements That Address the Completeness, Accuracy, or Consistency of XBRL-Tagged Data. The statement represents the recommendations of the XBRL Assurance Task Force of the AICPA Assurance Services Executive Committee regarding the application of Statements on Standards for Attestation Engagements to engagements in which a practitioner performs and reports on agreed-upon procedures related to the completeness, accuracy or consistency of XBRL-tagged data. SOP 09-1 is effective upon issuance. This Statement of Position provides practitioners with guidance on performing agreed-upon procedures engagements that address the completeness, accuracy, or consistency of an entity's XBRL-tagged data of information as of a specified date and for a specified period. The engagement is performed under AT section 201, Agreed- Upon Procedures Engagements (AICPA, Professional Standards, vol. 1) and this SOP includes guidance to assist practitioners in applying certain aspects of AT section 201 to the subject matter of XBRL.
