These are items the company does not state in this document. We do not leave them blank, nor fill them in from other sources or by inference.

The reasons the company gives

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

The remaining Series 13 Stock Acquisition Rights will be acquired and cancelled because the timing and volume of future exercises have become difficult to forecast in light of the share price level and market conditions, and the related financing will therefore be discontinued. The financing through the Series 14 Stock Acquisition Rights and bonds will be conducted to secure funding for the domestic development of the glaucoma treatment drug “H-1337.”
