Non-GAAP Financial Measures

     The following summarizes unaudited non-GAAP financial measures for Covanta Energy Corporation (“Covanta”). Certain items are included in the Historical Financials below that are not measured under U.S. generally accepted accounting principles (“GAAP”) and are not intended to supplant other information provided by Covanta in accordance with GAAP. Furthermore, these measures may not be comparable to those used by other companies. The following information should be read in conjunction with the Historical Financials set forth below. Adjusted EBITDA means, for any period, EBITDA plus additional items deducted from net income, as provided below, that have been made to EBITDA. Adjusted EBITDA is not a measurement of financial performance under GAAP and should not be considered as an alternative to cash flow from operating activities or as a measure of liquidity or an alternative to net income as indicators of Covanta’s performance or any other measures of performance derived in accordance with GAAP. The presentation of Adjusted EBITDA is intended to enhance the usefulness of the financial information by providing a measure which management uses as an indicator of Covanta’s ability to meet prospective financial covenants. Adjusted EBITDA for each of the periods set forth in the Historical Financials below is reconciled to net income, which is believed to be the most directly comparable measure of GAAP.

1.   “Write-down of assets held for use” includes charges relating to the following discrete events, each of which is related to a disposition of a non-core business in the Covanta bankruptcy or to entities that have declared bankruptcy or are being liquidated, and accordingly none are capable of recurrence:

•   During 2002, relating to impairment of the contract value on Covanta’s Battan energy project in the Philippines, because a potential contract extension in 2004 was determined to be unlikely ($37.2 million). This contract was subsequently terminated in 2004 and the project’s assets are currently being sold for scrap.

•   During 2002, relating to impairment of the contract value on Covanta’s Magellan energy project in the Philippines, because of material fuel price increases without corresponding increases in electricity tariffs ($41.7 million). This project subsequently filed for bankruptcy protection in the Philippines; its future is uncertain.

•   During 2002, relating to impairment of the contract value on Covanta’s entertainment business in Ottawa, Canada which it disposed of as part of its bankruptcy in 2003 ($6.0 million).
