More Executives Leave Security Environmental in Shake-Up : Auditing: The waste company again delayed release of a review of its finances for the fiscal year that ended June 30.

In a continuing shake-up, Security Environmental Systems Inc. said Monday that four more top managers, including the chief financial officer and controller, had left the waste management company.

In recent weeks, other senior company executives had left or been terminated by company President Ellen Batzel, including the company’s founder Alfred Grossman.

Grossman was removed as chairman of the board on Oct. 10. His two sons, Stephen and Jonathan, resigned in mid-September.

Batzel declined to offer explanations for the most recent departures. “All I can say is it was in the best interest of the company that they no longer work here,” she said.

Security Environmental said it has rehired William Sheridan, who had been its chief financial officer from October, 1992, through June, 1993, as interim chief financial officer. He has replaced Feleke Teka, who joined Security Environmental in September, as chief financial officer.

Drusilla Westall, a 10-year veteran of Security Environmental who was controller in the company’s South Carolina office, has been appointed interim controller.

Patrick Owens has joined Security Environmental as transportation manager in Fontana, Calif. He was formerly with Rollins OPC, a hazardous waste transportation company in Los Angeles. No replacement for the company’s billing manager has been announced.

The company, which provides waste remediation and transportation services, also said Monday that it would further delay reporting the results of an audit of its fiscal year ended June 30. It had previously announced that it would release the audit Monday.

The company earlier said that it expects to restate one or more quarterly statements for fiscal 1994 and continues to study the possibility of restating its financial statement for the fiscal year ended June 30, 1993.

“The audit turned out to be more difficult than we thought,” Batzel said. “There are issues that have been raised in it that surprised me. I am not at liberty to discuss them.”

Batzel said that Security Environmental now expects to file the necessary documents with the Securities and Exchange Commission by the end of November.

Security Environmental’s stock closed at $1.81 on Monday, up six cents in Nasdaq trading.
