[1] For the six months ended September 30, 2012, Nomura recognized an impairment loss on goodwill of \8,293 million within the Wholesale segment. This is due to a decline in fair value of a reporting unit in the Wholesale segment caused by the prolonged economic downturn. For the six months ended September 30, 2013, Nomura recognized impairment loss on goodwill of \2,047 million within Other in Nomura's segment information. This is due to a decline in fair value of a reporting unit caused by the decrease in expected cash flows arising from the changes in the economic environment. These impairment losses were recorded within Non-interest expenses-Other in the consolidated statements of income. The fair values were determined using a DCF valuation technique.
