104 The Certificate provides for the right of holders of Class A common stock to convert their stock into Class B common stock on a one-for-one basis at any time. The exchangeable shares are exchangeable at any time, at the option of the holder on a one-for-one basis for corresponding shares of Molson Coors common stock. Therefore, a portion of our authorized and unissued Class A and Class B common shares are reserved to meet exchange requirements. Each holder of record of Class A common stock, Class B common stock, Class A exchangeable shares and Class B exchangeable shares is entitled to one vote for each share held, without the ability to cumulate votes on the election of directors. Our Class B common stock has fewer voting rights than our Class A common stock and holders of our Class A common stock have the ability to effectively control or have a significant influence over company actions requiring stockholder approval. Specifically, holders of Class B common stock voting together as a single class have the right to elect three directors of the Molson Coors Board of Directors, as well as the right to vote on certain additional matters as outlined in the Restated Certificate of Incorporation (as amended, the “Certificate”), such as merger agreements that require approval under applicable law, sales of all or substantially all of our assets to unaffiliated third parties, proposals to dissolve MCBC, and certain amendments to the Certificate that require approval under applicable law, each as further described and limited by the Certificate. The Certificate also provides that holders of Class A common stock and Class B common stock shall vote together as a single class, on an advisory basis, on any proposal to approve the compensation of MCBC's named executive officers. The Class A exchangeable shares and Class B exchangeable shares were issued by Molson Coors Canada Inc. ("MCCI"), a wholly-owned subsidiary of the Company. The exchangeable shares are substantially the economic equivalent of the corresponding shares of Class A and Class B common stock that a Molson shareholder would have received in the merger of Adolph Coors Company with Molson Inc. in February 2005, if the holder had elected to receive shares of Molson Coors common stock. Exchangeable shareholders receive the CAD equivalent of dividends declared on Class A and B common stock on the date of declaration. Holders of exchangeable shares also receive, through a voting trust, the benefit of Molson Coors voting rights, entitling the holder to one vote on the same basis and in the same circumstances as one corresponding share of Molson Coors common stock.
