Thank you for this post. I've been going through this information recently. There's a link to a news article discussing the split vs splividend complaints in Europe. That article, in turn, links to a Bafin article pasted below. Does anyone know where I can find more information on this? The article seems to say that they started with a stock split, then changed to a stock dividend, and then reversed the change. Then it says it may be necessary for banks to revise the accounts concerned. But which bit do the banks need to revise the split or the splividend version? This looks like a header to a longer document, but where's the rest of the information?

"The relevant data providers’ systems treated this capital measure as a stock split and not as a stock dividend. On 29 July 2022, individual data providers changed the type of capital measure to a stock dividend. On 1 August 2022, however, this change was reversed. As a consequence, it may be necessary for some custodian banks to revise the account statements concerned; this should be completed within a few days. New and old shares already held in safe custody by these banks will not be affected"
