As a Nordea customer, I have the same observation specifically regarding Telia Oyj’s dividend payment hitting the account later than with other companies. Generally, dividends from domestic companies hit the account on the payment date in the morning after about 06:00. Telia’s dividend—since it’s not a domestic company—only hits the account in the afternoon. A few times, not until the next day. I’ve wondered if the company’s coffers are empty 
US companies are good at paying dividends on the payment date, but here in this backwater, they only show up in the account in the afternoon, though occasionally they also come the next day.
