As a side effect, that will also impact the gap between ex-div and record dates.
Currently, when a stock shows a record date at "Close on Wednesday", it will trade ex-div from Open Monday morning, a gap of three trading days.
After the move to T+2. ex-div and record day will be only two trading days apart, which means a Record Date Wednesday translates to ex-div being Tuesday.
