A banker at the center of a trading scheme German prosecutors say resulted in hundreds of millions of euros of illegitimate tax rebates told a court the scheme had taken on an “industrial scale” involving a network of banks and other institutions.
Martin Shields, a former investment banker, said that a web of banks, investors and brokers had organized the circular trades, making multiple tax reclaims and sharing the profit.
“I am not before you to deny my involvement, but to explain it,” Shields told the court in Bonn on Wednesday.
The trial is the first in a wider investigation aimed at recovering billions from banks which prosecutors say profited from such schemes. Germany estimates the schemes cost it more than 5 billion euros ($5.5 billion) in total.
Prosecutors allege that players in the so-called cum-ex scheme misled the state into thinking a stock had multiple owners who were each owed a dividend and a tax credit.
Shields’ testimony is a critical building block in pursuing others potentially involved. The case, Germany’s biggest post-war fraud investigation, is being closely followed in London and Frankfurt, where much of the trading was organized, according to bankers and court documents.
German state prosecutor Anne Brorhilker this month outlined criminal charges against Shields and fellow British banker Nicholas Diable, who she said organized a network of traders and lenders to make double tax reclaims with sham share trades.
Brorhilker said the two men, who face a possible jail term and a state order to repay any profits they made, had been involved in organizing bogus share trades in companies including carmaker BMW and airline Lufthansa.
The alleged scheme involved trading shares rapidly around a syndicate of banks, investors and hedge funds to give the impression of numerous owners, each entitled to a tax rebate.
Shields, a 41-year-old engineering graduate, said he regretted his involvement in the trading scheme but that the practice was common knowledge in the industry and that he had no reason to believe at the time that it was legally questionable.
“This was not the clandestine approach of a few,” he said, describing it as the “clear and openly communicated expectation of most banks and their customers.”
Diable is expected to address the court on Thursday. His lawyer did not respond to a request for comment.
Brorhilker has estimated that the alleged scheme she is prosecuting cost Germany some 450 million euros in lost taxes.
