Apparently, T-Mobile has already recorded $64 million over the past two quarters for "merger-related" employee costs, and now we know exactly what that means. Deutsche Telekom has said that money will be used specifically to retain "top employees" in the case that the proposed merger does go through.
Of course, we still have no idea when that may be happening. The US government is still investigating the proposal, and while there has been a lot of vocal opposition to the plan, everything has been fairly quiet recently. As of right now, the best guess is that a decision will be made by the middle of 2012.
