The three-year fixed-rate bonds have a spread of 88 basis points over yen swaps and the five-year fixed-rate bonds have a spread of 106 basis points over yen swaps.

The five-year floating-rate bonds have a spread of 106 basis points over yen Libor.

Mitsubishi UFJ Securities, Nikko Citigroup and Nomura Securities were the joint-lead managers.
