Under the Luxembourg Company Law, an existing shareholder in a joint stock corporation has a preemptive right to subscribe for new shares to be issued by the corporation in proportion to the number of shares it holds in the joint corporation’s existing share capital. These preemptive rights do not apply to shares issued out of authorized share capital to the extent that the general meeting of shareholders, when creating the authorized share capital, authorized the Board of Directors to exclude such preemptive rights. The Luxembourg Company Law allows the exclusion of preemptive rights upon a shareholders’ resolution passed with a majority of at least two-thirds of the votes validly cast at the relevant general meeting of shareholders or by the Board of Directors based on the authorization of the general meeting of shareholders.
