heck we have noticed on this side of the pond, the Govco has given up on such worries, no merger has been turned down or held up because of the market share in over 8 years...
are you sure the Govco over there (where you are) is/are still looking at such things?
Over here they take 2 failing companies and decide they are "to big to fail" so they decide a winner and give the lesser of the "to big to fail" companies (that -are- failing) a wad of money to go play on their yachts, making an even bigger company that is also to big to fail..
