Casino cruise ship operator Genting Hong Kong has agreed to sell 3.29 percent of its stake in Norwegian Cruise Line Holdings (NCLH) to third party investors.

The Hong Kong Stock Exchange-listed company announced last week that it has entered an agreement with shareholders Apollo Funds and TPG Fund to sell a total of 15 million ordinary shares, or about 6.58 percent stake, in the Florida-headquartered NCLH.

Underwriters Citigroup Global Markets, Barclays Capital and Goldman Sachs have proposed to offer the shares “from time to time.”

There is no fixed price for the sale, but Genting Hong Kong expects to book a net gain of approximately US$90.1 million from the sale of its 3.29 percent stake, which is controlled by the casino company’s wholly owned subsidiary Star NCLC Holdings Ltd.
