Item 1. Exchange Act Reporting History

A.  Madeco S.A. (“Madeco”) first incurred the duty to file reports under Section 13(a) and Section 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) on or about May 28, 1993, after it filed a Registration Statement on Form F-1 with the Securities and Exchange Commission (the “SEC”) to register common shares, no par value (the “Common Shares”) and American Depositary Shares (the “ADSs”) representing 100 Common Shares under Section 12(g) of the Exchange Act. The ADSs are evidenced by American Depositary Receipts (the “ADRs”).

Madeco’s Common Shares and ADSs were listed on the New York Stock Exchange (the “NYSE”) on May 28, 1993 (the “NYSE Listing”). Madeco terminated the NYSE Listing on or around July 27, 2009, ten days after its Form 25 became effective. Madeco terminated its ADR facility on October 10, 2009. As of the filing of this Form 15F, no ADSs remain outstanding.

B.  Madeco has filed or submitted all reports required under Section 13(a) and 15(d) of the Exchange Act and the corresponding rules of the SEC for the 12 months preceding the filing of this Form 15F, and has filed at least one annual report under Section 13(a).

Madeco has not sold its securities in the United States in an offering registered under the United States Securities Act of 1933, as amended, during the 12 months preceding the filing of this Form 15F.

Item 3. Foreign Listing and Primary Trading Market

A.  Madeco’s Common Shares are traded on the Santiago Stock Exchange, the Chile Electronic Stock Exchange and the Valparaiso Stock Exchange in Chile, the primary trading market of the Common Shares (the “Primary Trading Market”).

B. Madeco has maintained a listing of its Common Shares for a period that is longer than the 12 months preceding the filing of this Form 15-F. Madeco’s Common Shares were initially listed on the Santiago Stock Exchange in 1980 and the Common Shares have been listed on the Santiago Stock Exchange since then.  

C. For the 12-month period from March 31, 2009 to March 31, 2010, the percentage of trading in the Common Shares that occurred in the Primary Trading Market was approximately 99.6%.
