Carnival Corp is looking to inject hundreds of millions of dollars in fresh debt into its balance sheet.

The Arnold Donald-led company is offering €600m ($778m) in 1% senior notes set to mature in 2029.

Proceeds from the debt will go toward "general corporate purposes", the New York-listed cruise major said in an SEC document filed Monday.

"Some or all of the net proceeds may be temporarily invested in short-term investment grade instruments, interest-bearing bank accounts, certificates of deposit, money market securities or government securities prior to use, or applied to repay short-term debt," Carnival said.

The Miami-based cruise major has $1.61bn in long-term debt, excluding $559m incurred this month with delivery of 3,660-berth Sky Princess (built 2019). Total debt stands at $9.4bn.

Carnival posted $1.78bn in net income for the third quarter about a month ago, up from $1.78bn during the same period in 2018.

Carnival's shares went up less than 1% to close at $43.13 Monday.
