I have both SolarCity and Tesla stock. If I understand this correctly, my SolarCity stock will be replaced at some ratio with TSLA stock but the two things I don't know are 1. What the ratio is, I assume this is something that moved based on stock price, but now that SCTY trading has halted is this set now or will it still change as TSLA shares fluctuate? 2. What happens to fractional shares. My SCTY holding is pretty small, so whatever ratio they pick I'll almost certainly have a good portion of my holding that doesn't divide evenly.
