RE:RE:PAGE 90 of ProspectusThe last day of trade will only be announced after both company special meetings have confirmed the votes for the merger. Once approval is done, they have a whole bunch of work in terms of both the TSX and NASDAQ listings to bring them to a close. One can imagine they have gotten a head start on this, knowing that they have majority of shares that are for the merger.
I have guidance from TD Bank that if your shares are held in your Canadian RRSP account, the new shares will show up there, shown in Canadian $ Value, but you won't be able to buy and sell on your own, as you may now, you'll have to go through an agent on the phone from their international trading desk. There is no deamed disposition when you held your shares in an RRSP. This also likely means that trading will be more expensive.
As for dividends, they are not taxed in RRSP accounts (so long as you direct that's where you want them to go), and this is a non-issue for the remainder of 2020 anyways as it was declared that dividends by Flutter would be stopped due to the COVID19 effects on company revenues.
