Anheuser-Busch InBev has rejected accusations of gender bias in its executive pay scale, following a lawsuit filed by Anheuser-Busch's ex-communications chief.

Francine Katz, who left A-B amid the InBev takeover of the brewer in December last year, has filed a lawsuit in St Louis, US, accusing the brewer of paying her less than her male predecessor on the group's strategy committee.

She has accused the group of gender bias in its pay and bonus scale and is seeking unspecified damages.

A spokesperson for A-B InBev said today that the brewer believes the complaints made in the lawsuit are unjustified.

"Our company firmly believes in treating all employees fairly and values the differences of all employees, specifically prohibiting any form of discrimination based on a person's gender, race, religion, sexual orientation, national origin, disability or other prohibited factors."       

The firm added: "We believe that, before she resigned from the company, Francine Katz was compensated fairly for her roles and responsibilities at Anheuser-Busch and treated in compliance with all relevant laws and internal standards."
