Cover image of annual report This is AEP’s second integrated report combining the Annual Report to Shareholders with the Corporate Sustainability Report. This is our fifth year of reporting our sustainability preformance. This website — www.AEPsustainability.com — includes significant data and information about AEP’s performance. This report is based largely on calendar year 2010 with exceptions for early 2011 data as noted. For more information about AEP, visit www.AEP.com.

AEP's report follows GRI's G3 Reporting Principles. In addition, we report on the performance indicators of the GRI Electric Utility Sector Supplement; this supplemental reporting provides greater insight into our specific industry and the issues we face. The performance indicators from this supplement were not final at the time this report was developed. Therefore, the indicators we are reporting on were still in draft form. AEP was one of two U.S. companies to pilot the indicators in the development of this supplement. We adhere to the GRI principles of materiality, stakeholder inclusiveness, sustainability context, completeness, comparability, accuracy, timeliness, clarity, reliability and boundary setting. Our report is also checked by GRI.
