Derivative Instruments And Hedging Activities

(13) DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

Derivatives are used by the Pepco Energy Services and Power Delivery segments to hedge commodity price risk, as well as by PHI, from time to time, to hedge interest rate risk.

The retail energy supply component of Pepco Energy Services, which is in the process of winding down, purchases energy commodity contracts in the form of electricity and natural gas futures, swaps, options and forward contracts to hedge commodity price risk in connection with the purchase of physical natural gas and electricity for distribution to customers. The primary risk management objective is to manage the spread between retail sales commitments and the cost of supply used to service those commitments to ensure stable cash flows and lock in favorable prices and margins when they become available.

Pepco Energy Services' commodity contracts that are not designated for hedge accounting, do not qualify for hedge accounting, or do not meet the requirements for normal purchase and normal sale accounting are marked to market through current earnings. Forward contracts that meet the requirements for normal purchase and normal sale accounting are accounted for using accrual accounting.

In the Power Delivery business, DPL uses derivative instruments in the form of swaps and over-the-counter options primarily to reduce gas commodity price volatility and to limit its customers' exposure to increases in the market price of natural gas. DPL also manages commodity risk with physical natural gas and capacity contracts that are not classified as derivatives. All premiums paid and other transaction costs incurred as part of DPL's natural gas hedging activity, in addition to all gains and losses related to hedging activities, are deferred under FASB guidance on regulated operations (ASC 980) until recovered from its customers through a fuel adjustment clause approved by the DPSC.

PHI also uses derivative instruments from time to time to mitigate the effects of fluctuating interest rates on debt issued in connection with the operation of their businesses. In June 2002, PHI entered into several treasury rate lock transactions in anticipation of the issuance of several series of fixed-rate debt commencing in August 2002. Upon issuance of the fixed-rate debt in August 2002, the treasury rate locks were terminated at a loss. The loss has been deferred in Accumulated Other Comprehensive Loss (AOCL) and is being recognized in income over the life of the debt issued as interest payments are made.

The tables below identify the balance sheet location and fair values of derivative instruments as of June 30, 2011 and December 31, 2010:

Under FASB guidance on the offsetting of balance sheet accounts (ASC 210-20), PHI offsets the fair value amounts recognized for derivative instruments and the fair value amounts recognized for related collateral positions executed with the same counterparty under master netting agreements. The amount of cash collateral that was offset against these derivative positions is as follows:

	June  30, 2011		December 31, 2010
	(millions of dollars)
Cash collateral pledged to counterparties with the right to reclaim (a)	$	78	$	122

(a) Includes cash deposits on commodity brokerage accounts

As of June 30, 2011 and December 31, 2010, all PHI cash collateral pledged related to derivative instruments accounted for at fair value was entitled to offset under master netting agreements.

Derivatives Designated as Hedging Instruments

Cash Flow Hedges

Pepco Energy Services

For energy commodity contracts that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative is reported as a component of AOCL and is reclassified into income in the same period or periods during which the hedged transactions affect income. Gains and losses on the derivative, representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness, are recognized in income. Effective January 1, 2011, Pepco Energy Services elected to no longer apply cash flow hedge accounting to its natural gas derivatives. Amounts included in AOCL for natural gas cash flow hedges will be reflected in earnings as the hedge transactions are completed.

Cash flow hedge activity during the three and six months ended June 30, 2011 and 2010 is provided in the tables below:

	Three Months Ended June  30,					Six Months Ended June  30,
	2011		2010			2011		2010
	(millions of dollars)
Amount of net pre-tax gain (loss) arising during the period included in accumulated other comprehensive loss	$	3	$	12		$	2	$	(78	)

Total net pre-tax loss reclassified into income		19		38			46		87
Net pre-tax gain on commodity derivatives included in accumulated other comprehensive loss	$	22	$	50		$	48	$	9

(a) For the three months ended June 30, 2011 and 2010, amounts of zero and less than $1 million, respectively, were reclassified from AOCL to income because the forecasted hedged transactions were deemed probable not to occur.

(b) For the six months ended June 30, 2011 and 2010, amounts of zero and less than $1 million, respectively, were reclassified from AOCL to income because the forecasted hedged transactions were deemed probable not to occur.

As of June 30, 2011 and December 31, 2010, Pepco Energy Services had the following types and quantities of outstanding energy commodity contracts employed as cash flow hedges of forecasted purchases and forecasted sales.

	Quantities
Commodity	June 30, 2011		December 31, 2010
Forecasted Purchases Hedges
Natural gas (One Million British Thermal Units (MMBtu))		—		8,597,106
Electricity (Megawatt hours (MWh))		2,417,760		2,677,640
Electricity Capacity (MW-Days)		—		34,730
Forecasted Sales Hedges

Power Delivery

All premiums paid and other transaction costs incurred as part of DPL's natural gas hedging activity, in addition to all of DPL's gains and losses related to hedging activities, are deferred under FASB guidance on regulated operations until recovered from customers through a fuel adjustment clause approved by the DPSC. The following table indicates the amounts of the net unrealized derivative gain (loss) deferred as a regulatory liability (regulatory asset) and the realized loss recognized in the Consolidated Statements of Income for the three and six months ended June 30, 2011 and 2010:

	Three Months  Ended June 30,						Six Months  Ended June 30,

Cash Flow Hedges Included in Accumulated Other Comprehensive Loss

The tables below provide details regarding effective cash flow hedges included in PHI's Consolidated Balance Sheet as of June 30, 2011 and 2010. Cash flow hedges are marked to market on the balance sheet with corresponding adjustments to AOCL. The data in the tables indicate the cumulative net loss after-tax related to effective cash flow hedges by contract type included in AOCL, the portion of AOCL expected to be reclassified to income during the next 12 months, and the maximum hedge or deferral term:

	As of June 30, 2011				Maximum Term
Contracts	Accumulated Other Comprehensive Loss After-tax (a)		Portion Expected to be Reclassified to Income during the Next 12 Months
	(millions of dollars)
Energy Commodity (b)	$	49	$	35	35 months
Interest Rate		11		1	254 months
Total	$	60	$	36

(a) AOCL on PHI's Consolidated Balance Sheet as of June 30, 2011, includes a $20 million balance related to minimum pension liability. This balance is not included in this table as the minimum pension liability is not a cash flow hedge.

(b) The unrealized derivative losses recorded in AOCL are largely offset by forecasted natural gas and electricity physical purchases for delivery to retail customers that are in gain positions and subject to accrual accounting. These forward purchase contracts are exempted from mark-to-market accounting because they either qualify as normal purchases under FASB guidance on derivatives and hedging or they are not derivative contracts. Under accrual accounting, no asset is recorded on the balance sheet for these contracts, and the purchase cost is not recognized until the period of distribution. Although Pepco Energy Services no longer designates its natural gas derivatives as cash flow hedges effective January 1, 2011, gains or losses previously deferred in AOCL as of December 31, 2010 would remain in AOCL unless it is probable that the hedged forecasted transaction will not occur. At June 30, 2011, the amount remaining in AOCL associated with natural gas derivatives was $41 million.

	As of June 30, 2010				Maximum Term
Contracts	Accumulated Other Comprehensive Loss After-tax (a)		Portion Expected to be Reclassified to Income during the Next 12 Months
	(millions of dollars)
Energy Commodity (b)	$	94	$	55	47 months
Interest Rate		20		3	266 months
Total	$	114	$	58

(a) AOCL on PHI's Consolidated Balance Sheet as of June 30, 2010, includes a $15 million balance related to minimum pension liability and a $32 million balance related to Conectiv Energy. These balances are not included in this table as the minimum pension liability is not a cash flow hedge and Conectiv Energy is reported as a discontinued operation.

(b) The unrealized derivative losses recorded in AOCL are largely offset by forecasted natural gas and electricity physical purchases for delivery to retail customers that are in gain positions and subject to accrual accounting. These forward purchase contracts are exempted from mark-to-market accounting because they either qualify as normal purchases under FASB guidance on derivatives and hedging or they are not derivative contracts. Under accrual accounting, no asset is recorded on the balance sheet for these contracts, and the purchase cost is not recognized until the period of distribution.

Other Derivative Activity

Pepco Energy Services

Pepco Energy Services holds certain derivatives that are not in hedge accounting relationships nor are they designated as normal purchases or normal sales. These derivatives are recorded at fair value on the balance sheet with changes in fair value recorded through income.

For the three and six months ended June 30, 2011 and 2010, the amount of the derivative gain (loss) for Pepco Energy Services recognized in income is provided in the table below:

	Three Months Ended June 30, 2011								Three Months Ended June 30, 2010

Power Delivery

DPL holds certain derivatives that are not in hedge accounting relationships nor are they designated as normal purchases or normal sales. These derivatives are recorded at fair value on the Consolidated Balance Sheets with the gain or loss for the change in fair value recorded in income. In accordance with FASB guidance on regulated operations, offsetting regulatory liabilities or regulatory assets are recorded on the Consolidated Balance Sheets and the recognition of the derivative gain or loss is deferred because of the DPSC-approved fuel adjustment clause. For the three and six months ended June 30, 2011 and 2010, the net amount of the unrealized derivative gain (loss) deferred as a regulatory liability (regulatory asset) and the net realized loss recognized in the Consolidated Statements of Income is provided in the table below:

	Three Months Ended June  30,						Six Months Ended June  30,

Contingent Credit Risk Features

The primary contracts used by the Pepco Energy Services and Power Delivery segments for derivative transactions are entered into under the International Swaps and Derivatives Association Master Agreement (ISDA) or similar agreements that closely mirror the principal credit provisions of the ISDA. The ISDAs include a Credit Support Annex (CSA) that governs the mutual posting and administration of collateral security. The failure of a party to comply with an obligation under the CSA, including an obligation to transfer collateral security when due or the failure to maintain any required credit support, constitutes an event of default under the ISDA for which the other party may declare an early termination and liquidation of all transactions entered into under the ISDA, including foreclosure against any collateral security. In addition, some of the ISDAs have cross default provisions under which a default by a party under another commodity or derivative contract, or the breach by a party of another borrowing obligation in excess of a specified threshold, is a breach under the ISDA.

Under the ISDA or similar agreements, the parties establish a dollar threshold of unsecured credit for each party in excess of which the party would be required to post collateral to secure its obligations to the other party. The amount of the unsecured credit threshold varies according to the senior, unsecured debt rating of the respective parties or that of a guarantor of the party's obligations. The fair values of all transactions between the parties are netted under the master netting provisions. Transactions may include derivatives accounted for on-balance sheet as well as those designated as normal purchases and normal sales that are accounted for off-balance sheet. If the aggregate fair value of the transactions in a net loss position exceeds the unsecured credit threshold, then collateral is required to be posted in an amount equal to the amount by which the unsecured credit threshold is exceeded. The obligations of Pepco Energy Services are usually guaranteed by PHI. The obligations of DPL are stand-alone obligations without the guaranty of PHI. If PHI's or DPL's credit rating were to fall below "investment grade," the unsecured credit threshold would typically be set at zero and collateral would be required for the entire net loss position. Exchange-traded contracts are required to be fully collateralized without regard to the credit rating of the holder.

The gross fair value of PHI's derivative liabilities, excluding the impact of offsetting transactions or collateral under master netting agreements, with credit risk-related contingent features on June 30, 2011 and December 31, 2010, was $90 million and $156 million, respectively, before giving effect to the impact of a credit rating downgrade that would increase these amounts or offsetting transactions that are encompassed within master netting agreements that would alter these amounts. As of those dates, PHI had not posted any cash collateral against the gross derivative liability. PHI's net settlement amount in the event of a downgrade of PHI's and DPL's senior unsecured debt rating to below "investment grade" as of June 30, 2011 and December 31, 2010, would have been approximately $143 million and $176 million, respectively, after taking into consideration the master netting agreements. At June 30, 2011 and December 31, 2010, normal purchase and normal sale contracts in a loss position increased PHI's obligation.

PHI's primary sources for posting cash collateral or letters of credit are its credit facilities. At June 30, 2011 and December 31, 2010, the aggregate amount of cash plus borrowing capacity under the primary credit facilities available to meet the future liquidity needs of PHI and its subsidiaries totaled $1.4 billion and $1.2 billion, respectively, of which $827 million and $728 million, respectively, was available to Pepco Energy Services.

(10) DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

DPL uses derivative instruments in the form of swaps and over-the-counter options primarily to reduce natural gas commodity price volatility and to limit its customers' exposure to increases in the market price of natural gas. DPL also manages commodity risk with physical natural gas and capacity contracts that are not classified as derivatives. All premiums paid and other transaction costs incurred as part of DPL's natural gas hedging activity, in addition to all gains and losses related to hedging activities, are deferred under FASB guidance on regulated operations (ASC 980) until recovered from its customers through a fuel adjustment clause approved by the DPSC.

The tables below identify the balance sheet location and fair values of derivative instruments as of June 30, 2011 and December 31, 2010:

Under FASB guidance on the offsetting of balance sheet accounts (ASC 210), DPL offsets the fair value amounts recognized for derivative instruments and fair value amounts recognized for related collateral positions executed with the same counterparty under master netting agreements. The amount of cash collateral that was offset against these derivative positions is as follows:

	June 30, 2011		December 31, 2010
	(millions of dollars)
Cash collateral pledged to counterparties with the right to reclaim	$	3	$	6

As of June 30, 2011 and December 31, 2010, all DPL cash collateral pledged related to derivative instruments accounted for at fair value was entitled to be offset under master netting agreements.

Derivatives Designated as Hedging Instruments

Cash Flow Hedges

All premiums paid and other transaction costs incurred as part of DPL's natural gas hedging activity, in addition to all of DPL's gains and losses related to hedging activities, are deferred under FASB guidance on regulated operations until recovered from customers through a fuel adjustment clause approved by the DPSC.

Other Derivative Activity

DPL holds certain derivatives that are not in hedge accounting relationships nor are they designated as normal purchases or normal sales. These derivatives are recorded at fair value on the Balance Sheets with changes in the fair value recorded in income. In accordance with FASB guidance on regulated operations, offsetting regulatory liabilities or regulatory assets are recorded on the Balance Sheets and the recognition of the derivative gain or loss is deferred because of the DPSC-approved fuel adjustment clause. For the three and six months ended June 30, 2011 and 2010, the net amount of the unrealized derivative gain (loss) deferred as a regulatory liability (regulatory asset) and the net realized loss recognized in the Statements of Income is provided in the table below:

Contingent Credit Risk Features

The primary contracts used by DPL for derivative transactions are entered into under the International Swaps and Derivatives Association Master Agreement (ISDA) or similar agreements that closely mirror the principal credit provisions of the ISDA. The ISDAs include a Credit Support Annex (CSA) that governs the mutual posting and administration of collateral security. The failure of a party to comply with an obligation under the CSA, including an obligation to transfer collateral security when due or the failure to maintain any required credit support, constitutes an event of default under the ISDA for which the other party may declare an early termination and liquidation of all transactions entered into under the ISDA, including foreclosure against any collateral security. In addition, some of the ISDAs have cross default provisions under which a default by a party under another commodity or derivative contract, or the breach by a party of another borrowing obligation in excess of a specified threshold, is a breach under the ISDA.

Under the ISDA or similar agreements, the parties establish a dollar threshold of unsecured credit for each party in excess of which the party would be required to post collateral to secure its obligations to the other party. The amount of the unsecured credit threshold varies according to the senior, unsecured debt rating of the respective parties or that of a guarantor of the party's obligations. The fair values of all transactions between the parties are netted under the master netting provisions. Transactions may include derivatives accounted for on-balance sheet as well as those designated as normal purchases and normal sales that are accounted for off-balance sheet. If the aggregate fair value of the transactions in a net loss position exceeds the unsecured credit threshold, then collateral is required to be posted in an amount equal to the amount by which the unsecured credit threshold is exceeded. The obligations of DPL are stand-alone obligations without the guaranty of PHI. If DPL's credit rating were to fall below "investment grade," the unsecured credit threshold would typically be zero and collateral would be required for the entire net loss position. Exchange-traded contracts are required to be fully collateralized without regard to the credit rating of the holder.

The gross fair value of DPL's derivative liabilities, excluding the impact of offsetting transactions or collateral under master netting agreements, with credit-risk-related contingent features on June 30, 2011 and December 31, 2010, was $17 million and $23 million, respectively, before giving effect to the impact of a credit rating downgrade that would increase this amount or offsetting transactions that are encompassed within master netting agreements that would alter these amounts. As of those dates, DPL had not posted any cash collateral against the gross derivative liability. DPL's net settlement amount in the event of a downgrade of DPL's senior unsecured debt rating to below "investment grade" as of June 30, 2011 and December 31, 2010, would have been approximately $16 million and $31 million, respectively, after taking into account the master netting agreements.

DPL's primary source for posting cash collateral or letters of credit are PHI's credit facilities. At June 30, 2011 and December 31, 2010, the aggregate amount of cash plus borrowing capacity under the PHI credit facilities available to meet the liquidity needs of PHI's utility subsidiaries was $595 million and $462 million, respectively.
