Please note that the following answer only applies to clients of our german Wealth offering.‌ 
If Scalable Capital identifies a more suitable ETF in an asset class, the exchange is carried out gradually for you. In contrast to a one-time sale of all old shares, an additional tax expense can be reduced in this way, if necessary.

Additional purchases in the event of further deposits or a higher target weighting of these asset classes are made exclusively in the new ETF, while sales always first reduce the holdings of the old product. The old fund is indicated to you by the marking "Phase-Out".
