Lazard put out this press release on the October div for LOR. Lazard set the record date for the div as 11.12.19 and then announced the ex date as 11.11.19. As everyone knows Nov 11 is Veteran's day & the banks are closed on that day even though the stock market will be open. Thus because the banks are closed the ex-div date can't occur on such a day so since the rec date is locked at 11.12.19, the ex div must be on the earliest day that banks are open to confirm the trade. As a result the ex-date is actually today & not Vet's Day. No need for concern though since the exchange reset all GTC bids with the div adjusted as of today so no windfall for buyers & no missed div for today's sellers.
