To introduce postal banking, it's a question of what services you introduce and how fast you introduce those services. To determine costs it's very difficult unless you're looking at a concrete plan, but just let me give you one example. In the United Kingdom, where they have a considerable postal banking system, which was increased by the Cameron government, they have 300 people of the total workforce of the post office who concentrate on postal banking, so that's is not a huge number of people who were hired specifically to look at postal banking.
