Here are some background facts on the two banks.  The combined employee base is 142K now, with nearly $1 bn in assets.

Their tier 1 capital if we take the % times the combined asset base, suggests the new Bank come in around $160 bn, which if I am correct, will make them the largest bank in the world, based on capital base.  However the accounting in a merger is not simply additive, so that isn’t definitive, but directionally the new UK Bank is enormous.
