1. Forced index buying is my bet
2. No, just not renew. However, when the contract closes, unless the bank wants to keep the position, they will sell it into the market. Unless there is an additional source of demand, this could put downward pressure on the share price, so in the month the contract ends, this could be quite costly to Fairfax. There is also the real possibility that a lot of investors are using the TRS as a proxy on IV and may choose to exit as well. Leverage works both ways. I would see this as a short term blip, but the market can react in pretty funky ways at time
3. Yes, but remember that this could be seen as a significant funding source for the buybacks to date.
