SYDNEY---Fortescue Metals Group Ltd. said it has completed a bond offering worth US$1.5 billion, twice the size it had initially sought because of strong demand.

Fortescue said the senior unsecured notes have an interest rate of 4.375% and are due to mature in April 2031.

"The successful completion of this offering will refinance our earliest debt maturity, extend our weighted average maturity on terms consistent with our existing debt and further optimizes Fortescue's capital structure," said Chief Financial Officer Ian Wells.
