The Company has performed all procedures reasonably necessary to identify all contracts (including those of its consolidated and unconsolidated subsidiaries), and has performed all procedures reasonably necessary to review such contracts for potential impact as a result of applying SEAS No. 133. Such SEAS No. '.33 impact has been considered in the preparation of the Company's financial statements as of June 30, 2001, as prescribed by SEAS No. 133. Additionally, all derivative contracts are entered into with counterpartics who are equivalent to investment grade. 22.

During 1999 and 2000, Enron through various subsidiaries has made loans to Elektro directly and through its wholly owned subsidiary. Approximately $264 million of such loans since April 1, 2000, which have not otherwise been formally contributed to Elektro as equity capital, have been classified as part of the Company's investment in Elektro as the loans are deemed to be of a long-term investment nature as defined in SEAS No. 52, Foreign Currency Translation. As such, Enron intends to continually extend the maturity dates of such loans and accordingly does not anticipate settlement of the loan for the foreseeable frture. 24. In January 2001, the shareholders of Elektro approved a stock split and subsequent book value redemption of a number of Elektro shares. The redemption liability of approximately 676 million Brazilian Real is scheduled to be paid in installments through 2005. Approximately 425 million Brazilian Real of such balance remaining at June 30, 2001 to be paid, net to Enron. has been classified as part of the Company's investment in Elektro as such amounts are deemed to be of a Long-term investment nature as defined in SEAS No. 52. As such, to the extent that such amounts are eventually paid, Enron intends to reinvest such proceeds upon receipt in the form of equity capital in Elektro or loans to Elektro, which would not be anticipated to be settled in the foreseeable future. 25. Enron South America Turbine LLC. a wholly owned subsidiary of Enron Corp, is party to a Construction Agency Agreement with Brazilian Power Development Trust related to the "RioGen", 'Elektrobolt", and the "Cuiaba II" Facilities. Pursuant to the Construction Agency Agreement, the Company has varioUs options to purchase or lease the facilities from Brazilian Power Development Trust.
