Investment EnvironmentAt the beginning of fiscal 2011 the yield on 10-year Japanese Government Bonds—the prime indicator of domestic long-term interest rates—stood at 1.28%. From that point, the yield hovered above 1% at times, mainly due to concerns about worsening public finances due to the recovery effort from the Great East Japan Earthquake. Nevertheless, the yield ended the fiscal year at 0.98%.In the domestic stock market, the Nikkei 225 Average started fiscal 2011 at ¥9,708.39. It then declined to ¥8,160.01 in November, reflecting concerns about the European debt crisis and the yen’s appreciation in foreign exchange markets. Thereafter, the domestic stock market picked up mainly on the back of buoyant U.S. stock markets and a weaker yen. As a result, the stock index ended the fiscal year at ¥10,083.56.On the foreign exchange markets, the yen stood at ¥83.48/$1 at the start of fiscal 2011. From there the dollar strengthened against a weaker yen, because of speculation about the possible ending of the U.S.’ monetary easing policy. Thereafter, the yen was bought over concerns about the European debt crisis and a U.S. economic slowdown, pushing the yen to a record post-war high of ¥75.98 against the dollar in October. The yen then returned to the upper ¥70 range mainly as a result of intervention by the Bank of Japan in the currency exchange market. The yen weakened further against the dollar, reflecting improved U.S. economic indicators and the Bank of Japan’s monetary easing policy, among other factors. Consequently, the exchange rate ended the fiscal year at ¥82.19/$1.March 31, 2011March 31, 2012Long-term interest rates (10-year JGB yield)1.25%0.98%Stock market (Nikkei 225 Average)¥9,755.10¥10,083.56Foreign exchange market (¥/$ rate)¥83.15¥82.19JGB: Japanese Government BondInvestment PolicyThe majority of our investments of funds are in long-term, fixed-income financial products.
