The Companies’ commitments to make payments in addition to these contractual commitments include their other liabilities reflected in their balance sheets, any funding obligations for their pension and other postretirement benefit plans, financial hedging activities, their collective bargaining agreements and Con Edison’s guarantees of certain obligations of its businesses.
See Notes E, F, O and “Guarantees” in Note H to the financial statements in Item 8.
Capital Resources Con Edison is a holding company that operates only through its subsidiaries and has no material assets other than its interests in its subsidiaries.
Con Edison expects to finance its capital requirements primarily through internally-generated funds and the sale of its securities.
The company does not expect to need to issue additional common equity in 2013.
Con Edison’s ability to make payments on its external borrowings and dividends on its common shares is also dependent on its receipt of dividends from its subsidiaries or proceeds from the sale of its securities or its interests in its subsidiaries.
For information about restrictions on the payment of dividends by the Utilities and significant debt covenants, see Note C to the financial statements in Item 8.
For information on the Companies’ commercial paper program and revolving credit agreements with banks, see Note D to the financial statements in Item 8.
The Utilities may finance their operations, capital requirements and payment of dividends to Con Edison from internallygenerated funds (see “Liquidity and Capital Resources – Cash Flows from Operating Activities” in Item 7), contributions of equity capital from Con Edison and external borrowings.
The Companies expect to meet their 2013 external financing requirements, including for maturing securities, through the issuance of between $1,000 million and $1,500 million of longterm debt.
The Companies require access to the capital markets to fund capital requirements that are substantially in excess of available internally-generated funds.
See “Capital Requirements,” above.
Each of the Companies believes that it will continue to be able to access capital, although capital market conditions may affect the timing of the Companies’ financing activities.
The Companies monitor the availability and costs of various forms of capital, and will seek to issue Con Edison common stock and other securities when it is necessary or advantageous to do so.
For information about the Companies’ long-term debt and short-term borrowing, see Notes C and D to the financial statements in Item 8.

M ANAGEMENT ’ S D ISCUSSION AND A NALYSIS OF F INANCIAL C ONDITION AND R ESULTS OF O PERATIONS – C ONTINUED Electric CECONY’s results of electric operations for the year ended December 31, 2011 compared with the year ended December 31, 2010 is as follows
## Table 2 ##
CECONY’s electric sales and deliveries, excluding off-system sales, in 2011 compared with 2010 were:
## Table 3 ##
(a) “Residential/Religious” generally includes single-family dwellings, individual apartments in multi-family dwellings, religious organizations and certain other not-for-profit organization CECONY’s electric operating revenues decreased $148 million in 2011 compared with 2010 due primarily to lower purchased power ($369 million) and fuel costs ($57 million), offset by higher revenues from the electric rate plan ($278 million, which reflects, among other things, reconciliations of costs for municipal infrastructure support and capital expenditures ($10 million)).
CECONY’s revenues from electric sales are subject to a revenue decoupling mechanism, as a result of which delivery revenues generally are not affected by changes in delivery volumes from levels assumed when rates were approved.
Other electric operating revenues generally reflect changes in regulatory assets and liabilities in accordance with the revenue decoupling mechanism and other provisions of the company’s rate plans.
See Note B to the financial statements in Item 8.
Electric delivery volumes in CECONY’s service area decreased 1.5 percent in 2011 compared with 2010.
After adjusting for variations, principally weather and billing days, electric delivery volumes in CECONY’s service area decreased 1.1 percent in 2011 compared with 2010 CECONY’s electric purchased power costs decreased $369 million in 2011 compared with 2010 due to a decrease in unit costs ($258 million) and purchased volumes ($111 million).
Electric fuel costs decreased $57 million in 2011 compared with 2010 due to lower sendout volumes from the company’s electric generating facilities ($39 million) and lower unit costs ($18 million).
CECONY’s electric operating income increased $146 million in 2011 compared with 2010.
The increase reflects primarily higher net revenues ($278 million, due primarily to the electric rate plan).
The higher net revenues were offset by higher operations and maintenance costs ($78 million), due primarily to higher pension expense ($99 million) and employees’ health care costs ($16 million), offset in part by lower regulatory assessments and fees ($52 million).
In addition, net revenues were offset by higher taxes other than income taxes ($21 million, principally property taxes) and depreciation and amortization ($33 million).
Most of the operating expenses attributable to major storms in 2011 and 2010 were deferred as a regulatory asset.

Asia-Pacific Acquisition On July 24, 2006, we completed the purchase of a fifty-six percent ownership interest in the merchant acquiring business of The Hongkong and Shanghai Banking Corporation Limited, or HSBC.
This business provides card payment processing services to merchants in the Asia-Pacific region.
The business includes HSBC’s payment processing operations in the following ten countries and territories: Brunei, China, Hong Kong, India, Macau, Malaysia, Maldives, Singapore, Sri Lanka and Taiwan.
Under the terms of the agreement, we initially paid HSBC $67.2 million in cash to acquire our ownership interest.
We paid an additional $1.4 million under this agreement during fiscal 2007, for a total purchase price of $68.6 million to acquire our ownership interest.
In conjunction with this acquisition, we entered into a transition services agreement with HSBC that may be terminated at any time.
Under this agreement, we expect HSBC will continue to perform payment processing operations and related support services until we integrate these functions into our own operations, which we expect will be completed in 2010.
The operating results of this acquisition are included in our consolidated statements of income from the date of the acquisition.
Business Description We are a leading payment processing and consumer money transfer company.
As a high-volume processor of electronic transactions, we enable merchants, multinational corporations, financial institutions, consumers, government agencies and other profit and non-profit business enterprises to facilitate payments to purchase goods and services or further other economic goals.
Our role is to serve as an intermediary in the exchange of information and funds that must occur between parties so that a payment transaction or money transfer can be completed.
We were incorporated in Georgia as Global Payments Inc.  in September 2000, and we spun-off from our former parent company on January 31, 2001.
Including our time as part of our former parent company, we have provided transaction processing services since 1967.
We market our products and services throughout the United States, Canada, Europe and the Asia-Pacific region.
We operate in two business segments, merchant services and money transfer, and we offer various products through these segments.
Our merchant services segment targets customers in many vertical industries including financial institutions, gaming, government, health care, professional services, restaurants, retail, universities and utilities.
Our money transfer segment primarily targets immigrants in the United States and Europe.
See Note 10 in the notes to consolidated financial statements for additional segment information and “Item 1A—Risk Factors” for a discussion of risks involved with our international operations.
Total revenues from our merchant services and money transfer segments, by geography and sales channel, are as follows (amounts in thousands):
