TORONTO -- Brookfield Properties Corporation (TSX:BPO)(NYSE:BPO) announced today that the Toronto Stock Exchange accepted a notice filed by Brookfield of its intention to renew its existing normal course issuer bid for a further one year period.

In addition, Brookfield has 6,312,000 Class A redeemable voting shares outstanding. The price to be paid for the shares will be the market price at the time of purchase. The actual number of shares to be purchased and the timing of such purchases will be determined by Brookfield, and all shares will be purchased on the open market or such other means as approved by the Toronto Stock Exchange and the New York Stock Exchange. All shares purchased by Brookfield under this bid will be promptly cancelled.
