Notes to the Financial Statements — Continued The Utilities generally compute annual charges for depreciation using the straight-line method for financial statement purposes, with rates based on average service lives and net salvage factors.
The average depreciation rate for CECONY was 3.1 percent for 2011, 2010, and 2009.
The average depreciation rate for O&R was 2.8 percent for 2011, 2010, and 2009.
The estimated lives for utility plant for CECONY range from 5 to 80 years for electric, 5 to 85 years for gas, 5 to 70 years for steam and 5 to 50 years for general plant.
For O&R, the estimated lives for utility plant range from 5 to 75 years for electric, 5 to 75 years for gas and 5 to 50 years for general plant.
At December 31, 2011 and 2010, the capitalized cost of the Companies’ utility plant, net of accumulated depreciation, was as follows:
## Table 2 ##
* Primarily distribution.
Under the Utilities’ current rate plans, the aggregate annual depreciation allowance in effect at December 31, 2011 was $877 million, including $834 million under CECONY’s electric, gas and steam rate plans that have been approved by the New York State Public Service Commission (NYSPSC).
Non-Utility Plant Non-utility plant is stated at original cost and consists primarily of land, telecommunication, gas storage and solar facilities that are currently not used within electric, gas or steam utility operations.
Depreciation on these assets is computed using the straight-line method for financial statement purposes over their estimated useful lives, which range from 3 to 30 years.
Goodwill In accordance with the accounting rules for goodwill and intangible assets, Con Edison is required to test goodwill for impairment annually.
Goodwill is tested for impairment using a two-step approach.
The first step of the goodwill impairment test compares the estimated fair value of a reporting unit with its carrying value, including goodwill.
If the estimated fair value of a reporting unit exceeds its carrying value, goodwill of the reporting unit is considered not impaired.
If the carrying value exceeds the estimated fair value of the reporting unit, the second step is performed to measure the amount of impairment loss, if any.
The second step requires a calculation of the implied fair value of goodwill.
See Note K and Note T.  Impairments In accordance with the accounting rules for impairment or disposal of long-lived assets, the Companies evaluate the impairment of long-lived assets, based on projections of undiscounted future cash flows, whenever events or changes in circumstances indicate that the carrying amounts of such assets may not be recoverable.
In the event an evaluation indicates that such cash flows cannot be expected to be sufficient to fully recover the assets, the assets are written down to their estimated fair value.
In accordance with the accounting rules for equity method and joint ventures, Con Edison Development recognized a pre-tax impairment charge of $5 million in 2009, related to its equity investment in an electric generating plant in Guatemala (which was sold in 2010).
No impairment charges were recognized in 2011 and 2010.
Revenues The Utilities and Con Edison Solutions recognize revenues for energy service on a monthly billing cycle basis.
The Utilities defer over a 12-month period net interruptible gas revenues, other than those authorized by the NYSPSC to be retained by the Utilities, for refund to firm gas sales and transportation customers.
The Utilities and Con Edison Solutions accrue revenues at the end of each month for estimated energy service not yet billed to customers.
Prior to March 31, 2009, CECONY did not accrue revenues for energy service provided but not yet billed to customers except for certain unbilled gas revenues accrued in 1989.
This change in accounting for unbilled revenues had no effect on net income.
See “Regulatory Assets and Liabilities” in Note B.  Unbilled revenues included in Con Edison’s balance sheet at December 31, 2011 and 2010 were $474 million (including $366 million for CECONY) and $633 million (including $473 million for CECONY), respectively.
CECONY’s electric and gas rate plans and O&R’s New York electric and gas rate plans each contain a revenue decoupling mechanism under which the company’s actual energy delivery revenues are compared on a periodic basis, with the authorized delivery revenues and the difference accrued, with interest, for refund to, or recovery from, customers, as applicable.
See “Rate Agreements” in Note B.
LIQUIDITY AND CAPITAL RESOURCES As of December 31, 2011, our principal sources of liquidity included cash, cash equivalents, our receivables securitization facility, and our revolving credit facility, as well as the availability of commercial paper and other sources of financing through the capital markets.
We had $1.8 billion of committed credit available under our credit facility, with no borrowings outstanding as of December 31, 2011.
We did not make any borrowings under this facility during 2011.
The value of the outstanding undivided interest held by investors under the receivables securitization facility was $100 million as of December 31, 2011, and is included in our Consolidated Statements of Financial Position as debt due after one year.
The receivables securitization facility obligates us to maintain an investment grade bond rating.
If our bond rating were to deteriorate, it could have an adverse impact on our liquidity.
Access to commercial paper as well as other capital market financings is dependent on market conditions.
Deterioration of our operating results or financial condition due to internal or external factors could negatively impact our ability to access capital markets as a source of liquidity.
Access to liquidity through the capital markets is also dependent on our financial stability.
We expect that we will continue to have access to liquidity by issuing bonds to public or private investors based on our assessment of the current condition of the credit markets.
At December 31, 2011 and 2010, we had a working capital surplus.
This reflects a strong cash position, which provides enhanced liquidity in an uncertain economic environment.
In addition, we believe we have adequate access to capital markets to meet cash requirements, and we have sufficient financial capacity to satisfy our current liabilities.
