| · | Depreciation and Amortization expenses decreased $5 million primarily due to the expiration of E&R amortization of deferred carrying costs in Virginia offset by increased depreciation resulting from environmental upgrades at APCo.                                                                                                                                     |
| · | Taxes Other Than Income Taxes increased $6 million primarily due to higher property taxes in Ohio.                                                                                                                                                                                                                                                                                  |
| · | Allowance for Equity Funds Used During Construction decreased $4 million primarily due to SWEPCo’s completed construction of the Stall Unit in June 2010.                                                                                                                                                                                                                     |
| · | Income Tax Expense increased $2 million primarily due to an increase in pretax book income and other book/tax differences which are accounted for on a flow-through basis and the regulatory accounting treatment of state income taxes, partially offset by the 2010 tax treatment associated with the future reimbursement of Medicare Part D retiree prescription drug benefits. |

| · | Retail Margins decreased $60 million primarily due to the following: |
|--------|----------------------------------------------------------------------|
|   | ·                                                               | A $46 million decrease primarily due to a 13% decrease in residential usage, a 5% decrease in commercial usage and lower retail rates. |
|   | ·                                                               | A $23 million decrease in rate relief primarily due to the expiration of E&R cost recovery in Virginia and the implementation of higher interim rates in Virginia in January and February 2010.  This decrease in retail margins had corresponding decreases of $17 million related to riders/trackers recognized in other expense items discussed below. |
|   | These decreases were partially offset by:                            |
|   | ·                                                               | A $21 million increase due to lower capacity settlement expenses under the Interconnection Agreement net of recovery in West Virginia and environmental deferrals in Virginia. |

| · | Other Operation and Maintenance expenses decreased $8 million primarily due to the following: |
|--------|-----------------------------------------------------------------------------------------------|
|   | ·                                                                                        | A $32 million decrease due to the deferral of storm costs and costs related to 2010 cost reduction initiatives.  These costs were deferred as a result of the approved modified settlement agreement of APCo’s West Virginia base rate case in March 2011. |
|   | ·                                                                                        | A $6 million decrease in employee-related expenses. |
|   | ·                                                                                        | A $6 million decrease primarily due to lower overhead line maintenance expenses. |

|   | These decreases were partially offset by:                                                     |
|   | ·                                                                                        | A $41 million increase due to the write-off of a portion of the Mountaineer Carbon Capture and Storage Project Product Validation Facility as denied for recovery by the WVPSC in March 2011. |
|   | ·                                                                                        | Depreciation and Amortization expenses decreased $8 million primarily due to the expiration of E&R amortization of deferred carrying costs in Virginia, partially offset by an increased depreciation base resulting from environmental upgrades at the Amos Plant. |
|   | ·                                                                                        | Income Tax Expense decreased $14 million primarily due to a decrease in pretax book income. |

| (a) | Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.  Level 1 inputs primarily consist of exchange traded contracts that exhibit sufficient frequency and volume to provide pricing information on an ongoing basis.                                                                                                                                                                                                                                                                                                                 |
|-----|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| (b) | Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.  If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability.  Level 2 inputs primarily consist of OTC broker quotes in moderately active or less active markets, exchange traded contracts where there was not sufficient market activity to warrant inclusion in Level 1 and OTC broker quotes that are corroborated by the same or similar transactions that have occurred in the market.  |
| (c) | Level 3 inputs are unobservable inputs for the asset or liability.  Unobservable inputs shall be used to measure fair value to the extent that the observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date.  Level 3 inputs primarily consist of unobservable market data or are valued based on models and/or assumptions.                                                                                                                                                                                                          |
| (d) | Dedesignated Risk Management Contracts are contracts that were originally MTM but were subsequently elected as normal under the accounting guidance for “Derivatives and Hedging.”  At the time of the normal election, the MTM value was frozen and no longer fair valued.  This will be amortized into Revenues over the remaining life of the contracts.                                                                                                                                                                                                                                                                                     |
