I had done consulting work for AT&T and helped them set up an S&P 500 index fund that they managed internally. Along the way, I said, "You really don’t need an S&P 500 index fund." They had 100 managers managing equities for them and one big index fund, and none of these 100 managers was holding stocks of smaller companies in a meaningful way. If you want to index something, why not index stuff outside the S&P, the smaller companies? Eventually they agreed to do that. I told people what we were doing and there was a lot of interest. One of my colleagues said there might be a business in this. I thought about how we would set it up, and that was really the genesis.
