The reasons the company gives

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

Interest expenses consisted of the amortization of issuance discounts arising upon the issuance of convertible bonds with share acquisition rights and bonds, and interest on the convertible bonds with share acquisition rights. The decrease in foreign exchange losses resulted from foreign exchange gains arising from exchange-rate movements, while impairment losses were recognized because assets showing indications of impairment were written down to their recoverable amounts.
