Answer
At the end of 2014, Mikhail Khodorkovsky was worth $500 million. This was down from his peak wealth of $15 billion in 2003, when he was the richest man in Russia. Khodorkovsky's wealth was seized by the Russian government in 2003, and he was sentenced to 10 years in prison. He was released in 2013 and has since been living in exile in Switzerland.
