In May of 2017, Sunoco and ETP performed a merger. If your club held ETP at the time, this can be handled as a 3 for 2 Stock Split transaction.
If your club held Sunoco, or held both ETP and Sunoco at the time, we are continuing to work on steps for how to handle those cases. If your club is in this group, please reply back to this email, and we will let you know as soon as we have steps worked out for how to handle those transactions.
