| (3) | The      PUCO approved rate stabilization plans (RSP) filed by CSPCo and OPCo that      began after the market development period and extended through December      31, 2008 during which OPCo’s retail generation rates increased 7% annually      and CSPCo’s retail generation rates increased 3%      annually.  Distribution rates were frozen, with certain      exceptions, through December 31, 2008.  Pursuant to the Ohio      Amendments, in July 2008, CSPCo and OPCo filed ESP with the PUCO to      establish rates for 2009 through 2011.  CSPCo and OPCo have      requested retroactive application of the new rates, including the fuel      cost recovery mechanism, back to January 1, 2009 upon approval of the      ESP.  In December 2008, the PUCO ordered that CSPCo and OPCo      continue using their current RSP rates until the PUCO issues a ruling on      the ESP or the end of the February 2009 billing cycle, whichever comes      first.  In January 2009, CSPCo and OPCo filed an application      with the PUCO requesting the PUCO to authorize deferred fuel accounting      beginning January 1, 2009.  See Note 4 to the consolidated      financial statements, entitled Rate      Matters. |

| (4) | TCC      and TNC are no longer in the retail generation supply      business.  TCC and TNC provide only regulated delivery services      in ERCOT.  SWEPCo is vertically integrated utility that provides      retail electric service in the SPP area of  Texas. |

| (5) | Rates      in Virginia were capped, subject to adjustment, through      2008.  Beginning January 1, 2009, rates are neither capped nor      frozen. |
|-----|---------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (6) | If      the monthly off-system sales profits do not meet the monthly level built      into base rates, ratepayers reimburse KPCo for a portion of the      shortfall.  If the monthly off-system sales profits exceed the      monthly base amount built into base rates, KPCo reimburses ratepayers for      a portion of the excess. |
|-----|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (7) | Prior      to January 1, 2009, base rates for power supply were not capped or      frozen.  Effective January 1, 2009, base rates for power supply      will phase-in increases of $24 million, $3 million and $9 million for the      years beginning January 1, 2009, 2010 and 2011,      respectively.  Any filing to increase the amount Kingsport pays      for the non-fuel component of its purchase power, other than as discussed      above, cannot be made prior to January 1,2012. |

|      With      input from its state utility commissions, the AEP System continuously      assesses the adequacy of its generation, transmission, distribution and      other facilities to plan and provide for the reliable supply of electric      power and energy to its customers. In this assessment process, assumptions      are continually being reviewed as new information becomes available, and      assessments and plans are modified, as appropriate.  AEP      forecasts $2.6 billion of construction expenditures, excluding AFUDC, for      2009, which is a significant reduction from the original 2009 capital      forecast set in 2008.  Estimated construction expenditures are      subject to periodic review and modification and may vary based on the      ongoing effects of regulatory constraints, environmental regulations,      business opportunities, market volatility, economic trends, and the      ability to access capital.  Due to recent credit market      instability, we reviewed our projections for capital expenditures for 2009      and 2010.  We identified reductions of approximately $750      million for 2009.  We are evaluating possible additional      capital reductions for 2010. |

| (3)    | Tax      fees consisted principally of tax compliance services.  Tax      compliance services are services rendered based upon facts already in      existence or transactions that have already occurred to document, compute,      and obtain government approval for amounts to be included in tax      filings.  The decrease from 2007 relates primarily to additional      work performed in 2007 to assist the Company in connection with an      approved change in accounting method from the Internal Revenue      Service.                                                                                                              |
