The better test of how things are handled would be the units I bought this past August in my Zecco account. So far, no distribution there--but I don't know if that is just a delay at Zecco (Schwab is MUCH better at being on top of these things, and ALWAYS posts things more real-time than does Zecco), or if no dist for me was sent to Zecco due to not being a unit holder of record back in February but it will eventually get there as brokers work through it, or no distribution is coming.
My guess is door number 2.
Does anyone else out there hold units at Zecco that were purchased before Feb 22?
