BMW AG sold $4 billion of high-grade U.S. bonds ahead of the Federal Reserve’s interest rate decision on Wednesday. The company sold the bonds in six tranches through its subsidiary BMW US Capital LLC, according to people familiar with the matter. The longest-dated tranche was $500 million of 10-year bonds, which offered a yield of 1.15 percentage points over U.S. Treasuries, compared with an initial discussion of a yield of about 1.35 percentage points.
