Your dividend entitlement is determined based on your holdings at the close of trading the day before the distribution ex-date.
If your securities were held at your transferring bank at that time, the bank will process the dividend payment to your reference account on the pay date. This applies even if your holdings have already been transferred to Scalable Capital by the dividend payment date.
However, if your holdings had been transferred to Scalable Capital by the ex-dividend date, Scalable Capital will carry out the distribution.
