There are pieces of truths in virtually each of these posts.
I think we will always speculate about SPG buying the malls of GGP because: (1) they have the financial resources to do so, (2) SPG wants to grow their business and these GGP malls are the best collection of malls in the country that SPG could possibly acquire (Westfield and Taubman have great portfolios, but they will never be for sale), (3) GGP is now controlled by opportunistic investors who are not emotionally attached to the malls or committed to the retail real estate business and will sell their postiion when they beleive they are offered fair value.
I think what also fuels this speculation is the status of Spinco. It was clear that SPG wanted no part of those assets before; so spinning those assets out of GGP only makes the New GGP more attractive to SPG.
I never thought the anti trust issue was a deal breaker just something that was used by Management and the Hedgies to push SPG aside. I am sure SPG would agree not to acquire the centers where anti trust issues were a concern of the Feds, and a likely buyer of those centers could be BAM as they establish their retail platform.
All wild speculation, but I think we should get used to it. A few months ago, I started a thread saying that SPG will always be watching over GGP, waiting for the time when the Hedgies are ready to cash out. That has not changed.
I think the future of these assets is either in the SPG portfolio, or as the assets of BAM's retail portfolio. It will be up to either one to pay the Hedgies the fair value that they beleive these assets are worth. We will have to wait and see and just ride the coattails.
