(a) Derivative instruments and collateral were set off on the consolidated balance sheet as applicable under the accounting rules. The Companies enter into master agreements for their commodity derivatives. These agreements typically provide setoff in the event of contract termination. In such case, generally the non-defaulting party’s payable will be set-off by the defaulting party’s payable. The non-defaulting party will customarily notify the defaulting party within a specific time period and come to an agreement on the early termination amount.

(b) At December 31, 2014 and 2013, margin deposits for Con Edison ($27 million and $17 million, respectively) and CECONY ($25 million and $16 million, respectively) were classified as derivative assets in the balance sheet, but not included in the table. Margin is collateral, typically cash, that the holder of a derivative instrument is required to deposit in order to transact on an exchange and to cover its potential losses with its broker or the exchange.

Realized and Unrealized Gains or Losses on Commodity Derivatives

The following table presents the realized and unrealized gains or losses on commodity derivatives that have been deferred or recognized in earnings for the years ended December 31, 2014 and 2013:

(a) Con Edison recorded unrealized gains and losses in non-utility operating revenue ($4 million gain and an immaterial gain) and purchased power expense ($132 million loss and $74 million gain) for the years ended December 31, 2014 and 2013, respectively.

Hedged Volume of Derivative Transactions

The following table presents the hedged volume of Con Edison’s and CECONY’s derivative transactions at December 31, 2014:

	Electric Energy (MWHs)(a)(b)		Capacity (MWs)(a)		Natural Gas (Dt)(a)(b)
Con Edison		17,792,555		7,706		66,793,011
CECONY		5,543,250		2,100		62,065,000

(a) Volumes are reported net of long and short positions, except natural gas collars where the volumes of long positions are reported.

(b) Excludes electric congestion and gas basis swap contracts which are associated with electric and gas contracts and hedged volumes.

Aggregate Fair Value of Companies' Derivative Instruments with Credit-Risk-Related Contingent Features

The following table presents the aggregate fair value of the Companies’ derivative instruments with credit-risk-related contingent features that are in a net liability position, the collateral posted for such positions and the additional collateral that would have been required to be posted had the lowest applicable credit rating been reduced one level and to below investment grade at December 31, 2014:

(Millions of Dollars)	Con Edison(a)			CECONY(a)
Aggregate fair value – net liabilities	$	78		$	58
Collateral posted	$	1		$	-
Additional collateral(b) (downgrade one level from current ratings)	$	6		$	2
Additional collateral(b) (downgrade to below investment grade from current ratings)	$	105	(c)	$	63	(c)

(a) Non-derivative transactions for the purchase and sale of electricity and gas and qualifying derivative instruments, which have been designated as normal purchases or normal sales, are excluded from the table. These transactions primarily include purchases of electricity from independent system operators. In the event the Utilities and Con Edison’s competitive energy businesses were no longer extended unsecured credit for such purchases, the Companies would be required to post collateral, which at December 31, 2014, would have amounted to an estimated $16 million for Con Edison, including $3 million for CECONY. For certain other such non-derivative transactions, the Companies could be required to post collateral under certain circumstances, including in the event counterparties had reasonable grounds for insecurity.

(b) The Companies measure the collateral requirements by taking into consideration the fair value amounts of derivative instruments that contain credit-risk-related contingent features that are in a net liabilities position plus amounts owed to counterparties for settled transactions and amounts required by counterparties for minimum financial security. The fair value amounts represent unrealized losses, net of any unrealized gains where the Companies have a legally enforceable right of setoff.

(c) Derivative instruments that are net assets have been excluded from the table. At December 31, 2014, if Con Edison had been downgraded to below investment grade, it would have been required to post additional collateral for such derivative instruments of $15 million.
