Japan Tobacco shares fell 16% in Tokyo trading after the company's Russian divisions were placed under interim management, Nikkei Asia writes. According to analysts, the loss of control of the businesses in the Russian Federation could lead to the write-off of assets worth up to 1.3 trillion yen ($8.2 billion) and reduced dividends. The Russian market accounts for about 10% of sales and 25% of the operating profit of the Japanese manufacturer.
