The gift is worth $108m at today’s price for the cruiseship owner’s shares on the New York stock exchange.

Arne Alexander Wilhelmsen told the US Securities & Exchange Commission through a lawyer that he and the companies own 33.6 million shares in Miami-headquartered Royal Caribbean, which amounts to a 15.2% stake worth about $2.54bn.

Securities and stock exchange filings did not indicate who received the shares, other than to say that they remained within the Wilhelmsen family.
