Other assets (est.): the sum of each year's after-tax income (pay + dividends in own name − estimated taxes and social insurance) dividends retained by asset-management companies (less about 20% corporate tax), and proceeds from share sales (the drop in shares from the previous year × share price, less 20.315% tax, or about 30% for asset-management companies), for the years we have data. Spending, real estate, donations and savings from earlier years are not reflected.
