AEP Audit Services performed a review of the information included in this 2012 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 were reconciled to the source(s). The appropriateness of the context in which data are presented was verified as consistent with other public information disclosed by AEP. Based upon our review, we believe the information contained in the report as appropriately stated, and that the processes followed in accumulating both the financial and nonfinancial information are reasonable.
