Okay, I did a bit of research on the KRW amounts mentioned at the court hearing. I converted the sums at www.xe.com. All cents are rounded up and these numbers are not set in stone.
3,400,000,000 KRW = 2,990,858.71 USD
14.7 billion KRW = 12,935,296.38 USD
5 million KRW = 4,399.84 USD
9,000,000 KRW = 791,973.95 USD
