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

The aggregate fair value of all derivative instruments with credit-risk-related contingent features that are in a net liability position and collateral posted at September 30, 2013, 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 were:

(Millions of Dollars)	Con Edison (a)			CECONY (a)
Aggregate fair value – net liabilities		$31			$25
Collateral posted		$ —			$ —
Additional collateral (b) (downgrade one level from current ratings)		$ —			$ —
Additional collateral (b) (downgrade to below investment grade from current ratings)		$42	(c)		$29	(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 September 30, 2013, would have amounted to an estimated $35 million and $14 million for Con Edison and CECONY, respectively. 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 September 30, 2013, if Con Edison had been downgraded to below investment grade, it would have been required to post additional collateral for such derivative instruments of $37 million.
