ANA Holdings Inc.'s victory over rival Japan Airlines Co. in bidding for international flight slots from downtown Tokyo helped the nation's largest carrier triple the size of its first bond sale in two years. Demand for the 10-year bond offering on Feb. 28 exceeded expectations, helping the company raise 30 billion yen ($293 million) at a record-low yield of 1.22 percent, versus the originally planned issuance of 10 billion yen, ANA's spokesman Hideya Oishi said. That compares with a 1.46 percent average for similar-maturity debt sold by Japanese corporate borrowers, while companies worldwide pay 4.7 percent, according to Bank of America Merrill Lynch index data.
