Caterpillar Australian unit boosting debt

An Australian unit of Caterpillar Inc., the world's largest maker of construction equipment, added A$50 million ($44 million) to an existing line of bonds due in June 2012, according to data compiled by Bloomberg.

The floating-rate notes pay a coupon of 125 basis points more than the bank bill swap rate, the data show. Australia & New Zealand Banking Group Ltd. managed the sale.

Locally, Cat had operations in Montgomery.
