NEW YORK CITY—Brookfield Property Partners (BPY) said Thursday that its offer to buy the shares of GGP Inc. that it doesn’t already own still stands, although GGP’s board reportedly rejected the original bid this past December. The original cash-and-stock deal was valued at $23 per share, or approximately $14.8 billion.
