Their profit margin and ROE should be around 16% if you take out the one off 630,000k disposal of subsidary and 70,000k fair value of financial asset. Still pretty high, but its weird that they are borrowing and repaying roughly the same amount. Maybe to keep liabilities off book around reporting period? If that's the case, ROE may be lower than stated.
