The German authorities invaded Thursday morning at the ABN AMRO office in Frankfurt. Several German media reported it, while the bank itself was not immediately available for comment. It is probably about connected to the so-called Cum / Ex transactions. These are sales of shares around the dividend date where both buyer and seller reclaim dividend tax. That costs the tax authorities money. The authorities also visited the Frankfurt office in November. An ABN AMRO spokesperson then indicated that the authorities were looking for information and that the bank fully cooperated in the investigation. At the time, there were also searches in several homes in Germany. According to a statement from the German judicial authorities, about one hundred investigating officers participated in the raids.
