1. When was Edenor incorporated?
Edenor was incorporated as an Argentine limited liability corporation (sociedad anónima) on July 21, 1992 under the name Empresa Distribuidora Norte Sociedad Anónima. We were incorporated as part of the privatization of the Argentine state-owned electricity utility, Servicios Eléctricos del Gran Buenos Aires S.A. (SEGBA). In anticipation of its privatization, SEGBA was divided into three electricity distribution companies, including our company, and four electricity generation companies, and on May 14, 1992, the Argentine Ministry of Economy and Public Works and Utilities approved the public sale of all of our company's Class A shares, representing 51% of the capital stock of our company.

3. Who are Edenor's customers?
We have a highly concentrated, urban client base characterized by high purchasing power and low delinquency in payments of electricity bills.

8. Why are "tariffs" considered so important to Edenor?
Our revenues and margins are substantially dependent on the composition of our tariffs and on the tariff setting and adjustment process contemplated by our concession. We generally pass through to our customers the cost of our energy purchases and charge them a regulated distribution margin, or value-added for distribution (VAD), which is intended to cover our distribution costs (including depreciation and taxes) and provide us an adequate return on our asset base.

    or equal to 4000 kWh.
