UBS set to carve up Credit Suisse after takeover day

UBS is set to finalise the takeover of Credit Suisse today, but the hardest part is yet to come: turning the arranged marriage of Switzerland's biggest banks into a success.

On June 5, the two Zurich-based banks announced that the merger should be completed on June 12.

A merger this complex could turn out to be a nightmare, particularly given how little time UBS has had.
