Reflects deferrals of costs associated with certain current and prospective rider projects for Dominion Gas. See Note 12 for more information.


(3)	Legislation enacted in Virginia in April 2014 requires Virginia Power to defer operation and maintenance costs incurred in connection with the refueling of any nuclear-powered generating plant. These deferred costs will be amortized over the refueling cycle, but in no case for more than 18 months.


(4)	Reflects unrecovered gas costs at regulated gas operations, which are recovered through filings with the applicable regulatory authority.


(5)	For jurisdictions subject to cost-based rate regulation, changes in the fair value of derivative instruments result in the recognition of regulatory assets or regulatory liabilities as they are expected to be recovered from or refunded to customers.


(6)	Current regulatory assets are presented in other current assets in the Companies' Consolidated Balance Sheets.


(7)	Represents unrecognized pension and other postretirement employee benefit costs expected to be recovered through future rates generally over the expected remaining service period of plan participants by certain of Dominion's rate-regulated subsidiaries.


(8)	Amounts to be recovered through future rates to pay income taxes that become payable when rate revenue is provided to recover AFUDC-equity and depreciation of property, plant and equipment for which deferred income taxes were not recognized for ratemaking purposes, including amounts attributable to tax rate changes.


(9)	Under PIPP, eligible customers can make reduced payments based on their ability to pay. The difference between the customer's total bill and the PIPP plan amount is deferred and collected or returned annually under the PIPP rider according to East Ohio tariff provisions.


(10)	Current regulatory liabilities are presented in other current liabilities in the Companies' Consolidated Balance Sheets.


(11)	Rates charged to customers by the Companies' regulated businesses include a provision for the cost of future activities to remove assets that are expected to be incurred at the time of retirement.
