Norwegian Cruise Line Holdings is trying to raise $2bn in cash as the Frank Del Rio-led cruise major expresses concern over its ability to stay in business.

The New York-listed company, which has a $1.55bn credit line, on Tuesday announced plans to offer $1.25bn in bonds and $350m in shares while also allowing a $400m private equity investment.

The exchangeable senior notes, which will come due in 2024, are being sold through a private placement exempt from Securities and Exchange Commission rules, Norwegian said.
