So looking at the opportunities it's brought, well, banks already had big vaults holding the client's cash assets, so what banks decided to do was develop a range of services that allowed customers to hold assets with the bank that were not just cash. This made banks an ideal custodian provider. Custodian banks brought with them economies of scale as pension funds got larger and more diverse in what they invested in, a custodian bank was able to assist them, spread their investment portfolio as a custodian bank was already used to operating in those new markets. Some banks also decided to invest further in custody services and combined with economies of scale, brought new technologies and assisted the trustees of the pension funds achieve their regulatory objectives and expectations. The custodian banks also started to act as a go between the regulators, the local markets, and feeding information into the consultants that we use, both by the consultancy banks and also by the local regulators and the markets and the pension fund industries as to the types of instruments pension funds should be investing in.
