Form 10-K for the Fiscal Year Ended December 31, 2005 Filed February 17, 2006 File No. 1-3610 Dear Mr. Belda: We have limited our review of the above filing to disclosures relating to your contacts with countries that have been identified as state sponsors of terrorism, and we will make no further review of the filing. Our review with respect to this issue does not preclude further review by the Assistant Director group with respect to other issues. At this juncture, unless otherwise directed, we are asking you to provide us with supplemental information so that we may better understand your disclosure. Please be as detailed as necessary in your response. After reviewing this information, we may raise additional comments. Please understand that the purpose of our review process is to assist you in your compliance with the applicable disclosure requirements and to enhance the overall disclosure in your filings. We look forward to working with you in these respects. We welcome any questions you may have about our comments or on any other aspect of our review. Feel free to call us at the telephone numbers listed at the end of this letter. General 1. We note from page 83 of Exhibit 10(uu) that employees working abroad may opt for certain Alcoa-sponsored insurance covering Iran and Syria, countries identified as state sponsors of terrorism by the U.S. State Department and subject to sanctions administered by the U.S. Commerce Department`s Bureau of Industry and Security and the U.S. Treasury Department`s Office of Foreign Assets Control. We note that the Form 10-K does not contain any information relating to operations in, or ties to, Iran or Syria. Please describe your operations in, and ties to, these countries, if any, and discuss their materiality to you in light of their status as state sponsors of terrorism. Please also discuss whether the operations, either individually or in the aggregate, constitute a material investment risk to your security holders. Your response should describe your current, historical and anticipated operations in, and contacts with, Iran and Syria, including through subsidiaries, affiliates, joint ventures and other direct and indirect arrangements. 2. Your materiality analysis should address materiality in quantitative terms, including the approximate dollar amount of revenues, assets and liabilities associated with Iran and Syria. Please also address materiality in terms of qualitative factors that a reasonable investor would deem important in making an investment decision, including the potential impact of corporate activities upon a company`s reputation and share value. In this regard, we note that Arizona and Louisiana have adopted legislation requiring their state retirement systems to prepare reports regarding state pension fund assets invested in, and/or permitting divestment of state pension fund assets from, companies that do business with countries identified as state sponsors of terrorism. Your materiality analysis should address the potential impact of the investor sentiment evidenced by the referenced legislative actions directed toward companies operating in Iran and Syria. Please also address the impact of any regulatory compliance programs you have implemented in connection with business in Iran and Syria, and any internal risk assessment undertaken in connection with business in those countries. Please respond to these comments within 10 business days or tell us when you will provide us with a response. Please understand that we may have additional comments after reviewing your responses to our comments. Please file your response letter on EDGAR. We urge all persons who are responsible for the accuracy and adequacy of the disclosure in the filing to be certain that the filing includes all information required under the Exchange Act of 1934 and that they have provided all information investors require for an informed investment decision. Since the company and its management are in possession of all facts relating to the company`s disclosure, they are responsible for the accuracy and adequacy of the disclosures they have made. In connection with responding to our comments, please provide, in writing, a statement from the company acknowledging that: the company is responsible for the adequacy and accuracy of the disclosure in the filing; staff comments or changes to disclosure in response to staff comments do not foreclose the Commission from taking any action with respect to the filing; and the company may not assert staff comments as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.
