Do you know when DBS is going to call out preferential stock DBS Bk 4.7% NCPS?

Hello! It seems like you're referring to the following preferred shares issued by DBS: https://secure.fundsupermart.com/fsm/bonds/fact...

Am I right? If I'm right, then this particular preferred share issue can only be called back (or redeemed) by DBS on or after 22 November 2020. DBS has the right to choose when it wants to call back the preferred shares after the aforementioned date - meaning there is no guarantee that DBS will ever call back the preferred shares.
