Rivera, the company's at least fourth CEO in six years, is not entitled to and is not seeking any severance, SeaWorld said.

SeaWorld's revolving door of CEOs comes after its amusement parks came under scrutiny for its handling of orcas, documented in the 2013 film "Blackfish."
The documentary examined issues of animal captivity and exhibition of orcas, or killer whales, including by SeaWorld.
The company and an ex-CEO had agreed to pay more than $5 million to settle U.S. Securities and Exchange Commission charges in 2018 for misleading investors about the negative impact of the documentary.
Rivera's resignation was due to disagreements over the board's involvement in the decision making at the company, SeaWorld said, adding that he has stepped down from the board.
