Ensuring Your Vote is Counted

UAC advises holders of its securities to move their securities into accounts that do not permit the lending of securities, so called cash accounts or segregated accounts, and out of accounts that permit the lending of securities, such as margin accounts. These steps are designed to ensure that votes related to ordinary shares beneficially owned by shareholders are properly counted. Beneficial owners of ordinary shares that have been lent out (either with or without the beneficial owners’ knowledge) are not permitted to vote those shares.
