"Requests for the round up shares are to go to the DTC or the company"
If they are DTC eligible that is good, the ru's will be delivered much sooner than if they are not. 6 weeks.
"or the company" gives me some doubt. If not dtc eligible, each broker gets 1 master cert by mail, at the slow speed of the transfer agent. And some brokers do not request the correct # of shares. In that case 3-4 months at best.
