TOKYO -- An aggressive acquisitor, SoftBank had an interest-bearing debt of 9.22 trillion yen ($90.88 billion) at the end of December, up 150% from nine months earlier. Its interest payments on bank loans and corporate bonds are projected to rise to roughly 300 billion yen in fiscal 2014. If it acquires T-Mobile US later this year, its debt load would further increase to 12 trillion yen, according to one projection.
That would be a heavy debt burden for a company generating 6 trillion yen or so in annual revenues.
