Has nothing to do with Washington contacts since TNT is a European HQ company with limited presence in the US. Simply a marketshare issue. UPS has about 17% marketshare in Europe and if they acquired TNT would have been the largest player in Europe. FedEx has limited share in Europe and with the acquisition will now have about 17% share, leveling the playing field.
If I was an investor in TNT I would not approve the deal since UPS offered substantially more two years ago versus the FedEx offer. The shareholders should not approve the deal and should pressure FedEx for a better offer.
