Audit Review Of This Report
AEP Audit Services performed a limited review of company performance statements contained within the Business Performance Section of the 2013 AEP Corporate Accountability Report. Financial information was reconciled with AEP's audited financial statements, if applicable, or to such other sources as deemed appropriate. Processes used in accumulating the significant nonfinancial data were reviewed and the data reconciled to the sources(s). The appropriateness of the context in which data are presented was also reviewed. Finally, forward-looking information was verified as consistent with other public information disclosed by AEP. Based upon our review as of April 19, 2013, we believe the information regarding Business Performance is appropriately stated, and that the processes followed in accumulating both the financial and nonfinancial information are reasonable.
