Online travel company Expedia’s chief financial officer Michael Adler has decided to leave the company after six years in his position.

Adler will remain with the company during a transition period that will include the completion of the pending spin-off of TripAdvisor.

“During his tenure, Mike helped drive a doubling of our GAAP earnings per share, effectively steered the company through the global financial crisis and positioned us with a rock-solid balance sheet as we approach the date of the TripAdvisor spin-off,” said Dara Khosrowshahi, Expedia, Inc. president and CEO.

Mark Okerstrom, currently senior vice president of corporate development, will be appointed as the company’s new CFO and will assume the role after the transition period.

Okerstrom joined Expedia in 2006, and currently leads the company’s corporate strategic planning and mergers and acquisitions functions.
