Three months after his surprise confession, K1 Group founder Helmut Kiener was formally convicted of running a €345 million Ponzi scheme.
Kiener, who had loudly, repeatedly and, at times, threateningly, proclaimed his innocence since his arrest in 2009, was ordered jailed for 10 years and eight months by the Würzburg, Germany, court. K1's accountant, identified only as Claus Z., was also convicted and sentenced to three years and nine months in prison.
"Kiener's system only worked as long as he managed to acquire fresh funds," the court ruled. "His investors' chance to earn any return was almost zero. The case is extraordinary because of its size and the number of cheated investors."
Prosecutors say Kiener defrauded some 5,000 K1 clients, as well as its banks, Barclays and BNP Paribas, which lost €223 million on the scheme.
"My problem was that I didn't have the courage to end it all earlier," Kiener said after the sentencing. "Now I have to pay for it."
Kiener's lawyer said his client would not appeal, and that he was pleased that the sentence was two years and one month less than that sought by prosecutors.
