The reasons the company gives

The company's own explanation, not something inferred from the numbers.

The grant income was recognized because the final inspection of the grant associated with umedaptanib pegol receiving orphan drug designation was completed. The foreign exchange gain arose because the depreciation of the yen generated valuation gains on foreign-currency holdings. The impairment loss was recognized based on the accounting standard for impairment of fixed assets.
