Following impressive third-quarter results, previous CEO Scott Griffith announced that 2012 would mark Zipcar's "first full year of profitability on a US GAAP basis". Scott Griffith stepped down on March 15, 2013 following Avis Budget Group's acquisition of Zipcar. Mark Norman remained as president until February 2014, when Avis Budget Group announced that Kaye Ceille was appointed president of Zipcar, and "Mark Norman would step down in order to pursue another career opportunity." In July 2016, Kay Ceille stepped down as president of Zipcar to become the managing director of Avis Budget Group International, Australia. On January 5, 2017, Zipcar announced that after a 6-month search they appointed Tracey Zhen as its new president. Zhen came over from TripAdvisor where she had been a vice president and general manager.
