An example of how large collections of assets and large service networks don't have to have a 1:1 correspondence: I'm a member of a two-branch credit union, but I get to use a fairly extensive service network through the Credit Union Service Center system, where a large number of small institutions share the customer-service side of their operations. In the SF bay area, I get full service from any of the several dozen branches of Patelco and USE, plus several smaller CUs.
