I think Picon has the right idea. Contact your brokerage for info. Direct word from live chat with my brokerage: "Thank you for waiting with me. I spoke with our back office group and they confirmed that the spinoff distribution date is still set for today, but that we have not received those shares yet. However, with these spinoff dividends, they can come in at any time, so it is possible we may receive those shares later on in the day."
