Scott Topping has left his position as chief financial officer of Hawaiian Airlines.

The state’s largest carrier said Wednesday that he has been replaced on an interim basis by Shannon Okinaka, who had served as vice president-controller since 2011. Okinaka also will hold the role of senior vice president.

Hawaiian spokeswoman Ann Botticelli said she would not elaborate on the announcement and declined to say why or when Topping left and where he went. Topping participated on the company’s third-quarter earnings conference call on Oct. 21.

Topping, who joined Hawaiian on Nov. 1, 2011, was the fourth highest-paid executive at Hawaiian, according to the company’s latest proxy that was filed last April. In 2013, Topping received total compensation of $784,848, including a base salary of $330,000.
