(Adds CEO quote, background)

Sept 21 (Reuters) - Video game publisher Activision Blizzard said on Tuesday that it continues to work with regulators on addressing and resolving the workplace complaints it has received.

On Monday, the company said the U.S. securities regulator was investigating its disclosures regarding employment matters and related issues.

"There is absolutely no place anywhere in our company for discrimination, harassment, or unequal treatment of any kind," said Bobby Kotick, Activision's chief executive officer.

The U.S. Securities and Exchange Commission (SEC) had also issued subpoenas to the company and several of its current and former employees, seeking information regarding the matter.

The investigation comes at a time when Activision is embroiled in a lawsuit that alleges equal pay violations, sex discrimination and sexual harassment at the company. (https://reut.rs/3ECUCeE)
