Source: Moody's Financial Metrics Detailed Rating Considerations Diversity of regulatory jurisdictions and service territories provide a strong foundation for current rating AEP's diversity in terms of regulatory jurisdictions and service territory economies is a meaningful credit strength as it provides the company with a degree of insulation from any unexpected negative developments occurring at any one of its operating companies, state regulatory bodies or state economies. This diversity has been helpful in dealing with weak demand growth in some of AEP’s service territories while it spends heavily on environmental compliance and system reliability. Going forward, the largest portion of AEP’s capital program will be for investment in its Federally regulated transmission subsidiaries along with increased investment in transmission and distribution operations at its state regulated utility subsidiaries. AEP's primary state regulated utilities and their respective authorities are as follows: Ohio Power Company (OPCo: A2 stable), which accounted for 18% of AEP's total 2016 revenues, operates under the Public Utility Commission of Ohio (PUCO); Appalachian Power Company (APCo: Baa1 stable), which accounted for 18% of AEP's total 2016 revenues, operates under the Virginia State Corporation Commission (VSCC), (covering a little over half of APCo's customers) and the more challenging Public Service Commission of West Virginia (PSC WV); Indiana Michigan Power Company (I&M: Baa1 positive), 13% of AEP's total 2016 revenues, is regulated by the Indiana Utility Regulatory Commission (IURC), (about ¾ of I&M's customers) and the Michigan Public Service Commission (MPSC); Southwestern Electric Power Company (SWEPCo: Baa2 stable), 11% of AEP's total 2016 revenues, operates under the Louisiana Public Service Commission (LPSC) (about 43% of SWEPCo customers), the Arkansas Public Service Commission (ARPSC) (22% of SWEPCo customers) and the Public Utility Commission of Texas (PUCT) (35% of SWEPCo customers); Public Service Company of Oklahoma (PSO: A3 stable), 8% of AEP's total 2016 revenues, is regulated by the Oklahoma Corporation Commission (OCC); AEP Texas (AEP Texas: Baa1 stable), which was formed by the merger of AEP Texas Central and AEP Texas North Company at year-end 2016, 9% of AEP's total 2016 revenues, is regulated by the Public Utility Commission of Texas (PUCT); and Kentucky Power Company (KPCo: Baa2 stable), 4% of AEP's total 2016 revenues, is under the Kentucky Public Service Commission (KPSC). AEP Transmission Company LLC’s (AEP Transco: A2 stable) transmission businesses are regulated by the FERC under forward looking formulaic rate plans that result in a high degree of cash flow predictability. Operations are actively conducted through five subsidiaries within AEP's electric utility service territories in six states, Ohio, West Virginia, Kentucky, Oklahoma, Indiana and Michigan. The company is growing rapidly; net plant has more than doubled since 2013 and the company anticipates continued investment across its subsidiaries will result in another doubling by 2019. For further information on these service territories and subsidiaries please refer to each utility's credit opinion on Moodys.com. Continued regulatory support with timely and sufficient cost recovery important to credit quality Given the significant amount of capital expenditures AEP has planned across its regulated business segments, it is essential that AEP maintain a supportive relationship with its regulators to sustain credit quality.
