• In the United States, Alcoa intends to permanently close its Rockdale Operations site in Texas, which has been fully curtailed since the end of 2008. The site includes a primary aluminum smelter and casthouse, an aluminum powder plant and associated buildings and equipment. Alcoa's strategic review of these assets, announced earlier this year, concluded that these operations have limited economic prospects. Separately, the Company continues to market for sale more than 30,000 acres of land at the Rockdale site.
• In Italy, Alcoa has reached an agreement to divest the Portovesme primary aluminum smelter, fully curtailed since 2012 and closed since 2014, to Invitalia, the Italian government agency that manages economic development. As part of the agreement, Alcoa and the Italian government have settled matters related to past energy tariffs, including the Italian Energy Authority Regulation 148/2004 matter, and a groundwater remediation project.

Cash outlays for the Rockdale closure are expected to be approximately $53 million over the next five years, including holding and demolition costs, with approximately $16 million in 2018. Cash outlays for the Italy settlement, including the pre-existing 148/2004 matter and remediation reserves, are expected to be between $40 million and $50 million over the next five years, with approximately $10 million in 2018.

This press release contains statements that relate to future events and expectations and as such constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include those containing such words as "anticipates," "believes," "could," "estimates," "expects," "forecasts," "intends," "may," "outlook," "plans," "projects," "seeks," "sees," "should," "targets," "will," "would," or other words of similar meaning. All statements that reflect the Company's expectations, assumptions or projections about the future, other than statements of historical fact, are forward-looking statements. Forward-looking statements are not guarantees of future performance and are subject to known and unknown risks, uncertainties, and changes in circumstances that are difficult to predict. Although the Company believes that the expectations reflected in any forward-looking statements are based on reasonable assumptions, it can give no assurance that these expectations will be attained and it is possible that actual results may differ materially from those indicated by these forward-looking statements due to a variety of risks and uncertainties. Additional information concerning factors that could cause actual results to differ materially from those projected in the forward-looking statements is contained in our filings with the Securities and Exchange Commission.

Alcoa Corporation's definition of Adjusted EBITDA is net margin plus an add-back for depreciation, depletion, and amortization. Net margin is equivalent to Sales minus the following items: Cost of goods sold; Selling, general administrative, and other expenses; Research and development expenses; and Provision for depreciation, depletion, and amortization. Adjusted EBITDA is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because Adjusted EBITDA provides additional information with respect to Alcoa Corporation's operating performance and the Company's ability to meet its financial obligations. The Adjusted EBITDA presented may not be comparable to similarly titled measures of other companies. Alcoa Corporation has not provided a reconciliation of the forward-looking Adjusted EBITDA amounts included in this release to the most directly comparable GAAP financial measures due primarily to the variability and complexity in making accurate forecasts and projections, as not all of the information for a quantitative reconciliation is available to the company without unreasonable effort.
