Exhibit 99.1


         SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth certain information known to the Company with
respect to the beneficial ownership as of August 15, 2001, by (i) all persons
who are beneficial owners of five percent (5%) or more of the Company's Common
Stock (including Exchangeable Shares), (ii) each director and nominee, (iii) the
Named Executive Officers (defined below), and (iv) all current directors and
executive officers as a group.

As of August 15, 2001, 1,151,129,342 shares of the Company's Common Stock were
outstanding, and as of the same date, 172,872,190 Exchangeable Shares were
outstanding (excluding Exchangeable Shares owned by the Company and its
affiliates which are not voted). The amounts and percentages of Common Stock
beneficially owned are reported on the basis of regulations of the Securities
and Exchange Commission (the "Commission") governing the determination of
beneficial ownership of securities. Under the rules of the Commission, a person
is deemed to be a "beneficial owner" of a security if that person has or shares
"voting power," which includes the power to vote or to direct the voting of such
security, or "investment power," which includes the power to dispose of or to
direct the disposition of such security. A person is also deemed to be a
beneficial owner of any securities of which that person has a right to acquire
beneficial ownership within 60 days. Under these rules, more than one person may
be deemed a beneficial owner of securities as to which such person has no
economic interest.
