It was complicated technically, requiring not only a central build but also substantial work within financial institutions. And, as a large cross industry project it was complicated logistically. But despite this, and the fact that there is still work to do, it has been a successful project. I think there were a few things that contributed to the effective collaboration that delivered the NPP.
Discussions within the AIG on this issue - as well as bilateral discussions with affected banks and their supervisors - have been productive, and I think the associated problems will be addressed. However, one issue appears to be particularly difficult in more than one jurisdiction: the allocation of capital for operational risk among the legal entities within and across jurisdictions.
