Note O — Derivative Instruments and Hedging Activities Under the accounting rules for derivatives and hedging, derivatives are recognized on the balance sheet at fair value, unless an exception is available under the accounting rules.
Certain qualifying derivative contracts have been designated as normal purchases or normal sales contracts.
These contracts are not reported at fair value under the accounting rules.
Energy Price Hedging Con Edison’s subsidiaries hedge market price fluctuations associated with physical purchases and sales of electricity, natural gas, and steam by using derivative instruments including futures, forwards, basis swaps, options, transmission congestion contracts and financial transmission rights contracts.
The fair values of these hedges at December 31, 2012 and 2011 were as follows:
## Table 0 ##
Credit Exposure The Companies are exposed to credit risk related to transactions entered into primarily for the various energy supply and hedging activities by the Utilities and the competitive energy businesses.
The Companies use credit policies to manage this risk, including an established credit approval process, monitoring of counterparty limits, netting provisions within agreements, collateral or prepayment arrangements, credit insurance and credit default swaps.
At December 31, 2012, Con Edison and CECONY had $113 million and $19 million of credit exposure in connection with energy supply and hedging activities, net of collateral, respectively.
Con Edison’s net credit exposure consisted of $41 million with investment-grade counterparties, $41 million with commodity exchange brokers, $28 million with independent system operators and $3 million with noninvestment grade/non-rated counterparties.
CECONY’s net credit exposure consisted of $1 million with investment-grade counterparties and $18 million with commodity exchange brokers.
Economic Hedges The Companies enter into certain derivative instruments that do not qualify or are not designated as hedges under the accounting rules for derivatives and hedging.
However, management believes these instruments represent economic hedges that mitigate exposure to fluctuations in commodity prices.
facilities, were $3,735 million and $3,455 million at December 31, 2012 and 2011, respectively.
Natural gas is delivered by pipeline to CECONY at various points in its service territory and is distributed to customers by the company through an estimated 4,360 miles of main and 387,881 service lines.
The company owns a natural gas liquefaction facility and storage tank at its Astoria property in Queens, New York.
The plant can store approximately 1,000 mdths of which a maximum of about 250 mdths can be withdrawn per day.
The company has about 1,226 mdths of additional natural gas storage capacity at a field in upstate CECONY’s gas sales and deliveries for the last five years were: New York, owned and operated by Honeoye Storage Corporation, a corporation 28.8 percent owned by CECONY and 71.2 percent owned by Con Edison Development.
Gas Sales and Deliveries The company generally recovers the cost of the gas that it buys and then sells to its firm sales customers.
It does not make any margin or profit on the gas it sells.
CECONY’s gas revenues are subject to a weather normalization clause and a revenue decoupling mechanism.
As a result, its gas delivery revenues are generally not affected by changes in delivery volumes from levels assumed when rates were approved.
