2. “Safe Harbor” Statement under the Private
Securities Litigation Reform Act of 1995
This presentation contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934. Although AEP and each of its Registrant
Subsidiaries believe that their expectations are based on reasonable assumptions, any such statements may be influenced by factors that could cause actual outcomes
and results to be materially different from those projected. Among the factors that could cause actual results to differ materially from those in the forward-looking
statements are: the economic climate and growth in, or contraction within, our service territory and changes in market demand and demographic patterns, inflationary or
deflationary interest rate trends, volatility in the financial markets, particularly developments affecting the availability of capital on reasonable terms and developments
impairing our ability to finance new capital projects and refinance existing debt at attractive rates, the availability and cost of funds to finance working capital and capital
needs, particularly during periods when the time lag between incurring costs and recovery is long and the costs are material, electric load, customer growth and the impact
of retail competition, particularly in Ohio due to the February 2012 PUCO rehearing order, weather conditions, including storms, and our ability to recover significant storm
restoration costs through applicable rate mechanisms, available sources and costs of, and transportation for, fuels and the creditworthiness and performance of fuel
suppliers and transporters, availability of necessary generating capacity and the performance of our generating plants, our ability to resolve I&M’s Donald C. Cook Nuclear
Plant Unit 1 restoration and outage-related issues through warranty, insurance and the regulatory process, our ability to recover regulatory assets in connection with
deregulation, our ability to recover increases in fuel and other energy costs through regulated or competitive electric rates, our ability to build or acquire generating
capacity, and transmission line facilities (including our ability to obtain any necessary regulatory approvals and permits) when needed at acceptable prices and terms and
to recover those costs (including the costs of projects that are cancelled) through applicable rate cases or competitive rates, new legislation, litigation and government
regulation including oversight of nuclear generation, energy commodity trading and new or heightened requirements for reduced emissions of sulfur, nitrogen, mercury,
carbon, soot or particulate matter and other substances or additional regulation of fly ash and similar combustion products that could impact the continued operation and
cost recovery of our plants, a reduction in the federal statutory tax rate, timing and resolution of pending and future rate cases, negotiations and other regulatory decisions
including rate or other recovery of new investments in generation, distribution and transmission service and environmental compliance, resolution of litigation, our ability to
constrain operation and maintenance costs, our ability to develop and execute a strategy based on a view regarding prices of electricity, natural gas and other energy-
related commodities, changes in the creditworthiness of the counterparties with whom we have contractual arrangements, including participants in the energy trading
market, actions of rating agencies, including changes in the ratings of debt, volatility and changes in markets for electricity, natural gas, coal, nuclear fuel and other
energy-related commodities, changes in utility regulation, including the implementation of ESPs and the expected legal separation and transition to market for generation
in Ohio and the allocation of costs within regional transmission organizations, including PJM and SPP, accounting pronouncements periodically issued by accounting
standard-setting bodies, the impact of volatility in the capital markets on the value of the investments held by our pension, other postretirement benefit plans, captive
insurance entity and nuclear decommissioning trust and the impact on future funding requirements, prices and demand for power that we generate and sell at wholesale,
changes in technology, particularly with respect to new, developing or alternative sources of generation, our ability to recover through rates or prices any remaining
unrecovered investment in generating units that may be retired before the end of their previously projected useful lives, our ability to successfully manage negotiations with
stakeholders and obtain regulatory approval to terminate or amend the Interconnection Agreement and break up or modify the AEP Power Pool, evolving public perception
of the risks associated with fuels used before, during and after the generation of electricity, including nuclear fuel and other risks and unforeseen events, including wars, the
effects of terrorism (including increased security costs), embargoes, cyber security threats and other catastrophic events.
