If, in fact, it does end up being WBT/WLNK that get divested, I don't think you'll see them in a trust for very long. I believe it was Tom Taylor who reported that they do just under 20% of the market's revenue. Greater Media is the third largest biller in a growing market. That would have to be attractive to somebody.
If Beasley wants to keep WBT/WLNK, it would have to divest two FM's totaling about 15% of the market's billing. The same article mentioned Beasley's current cluster did just under 35% of the market's billing and would need to stay at or below 40% to satisfy the DOJ. Those numbers might not work. It's entirely possible, if not likely, that Beasley couldn't divest two FM's that would make adding WBT/WLNK worth the effort to add to the cluster.
