d) Natural gas derivative contract

In connection with the long-term contract to buy gas (“The Gas Supply Agreement” or "GSA") to supply thermoelectric plants and for other uses in Brazil, the Company entered into a contract, with the company Empresa Petrolera ANDINA, a gas producer in Bolivia, that constituted a derivative financial instrument under SFAS 133. This contract, the Natural Gas Price Volatility Reduction Contract (the "PVRC"), was executed with the purpose of reducing the effects of price volatility under the GSA.

The terms of the PVRC provided for a price collar for the period from 2005 to 2019, with the Company receiving cash payments when the calculated price is above the established ceiling, and the Company making cash payments when the price is below the established floor, with no cash payments being made when the price is between the ceiling and the floor.

Due to the new Hydrocarbons Law of Bolivia (see Note 18), the other party to the PVRC contested the contract, alleging among others, “force majeure” and excessive onus. Consequently, the Company adjusted the fair value asset and liabilities related to the PVRC by recording a financial expense of US$328 during the first quarter of 2006 as a result of the tax increases in Bolivia.

On August 12, 2006, the parties agreed to cancel the PVRC. As a result, on August 14, 2006 the Company received US$41, wrote-off accounts receivable related to the PVRC amounting to US$77, and wrote-off the remaining fair value asset of US$94 as a consequence of the cancellation of contract.
