SABMiller, the global brewer, has initiated a further realignment of responsibilities within the its executive committee.

As a result of this realignment, Catherine May, the group’s director of Corporate Affairs, will leave at the end of this month.

Chief financial officer, Jamie Wilson, will assume responsibility for investor relations alongside his other financial areas, while group director of Corporate Finance and Development, Domenic De Lorenzo, will assume additional responsibility for group strategy.

John Davidson will become general counsel and corporate affairs director and in light of his additional responsibilities will relinquish his role as company secretary.

Stephen Shapiro, currently deputy company secretary and deputy general counsel, will be appointed as company secretary from 1 November 2014, retaining his deputy general counsel role.

Alan Clark, chief executive, said: “This further realignment, following the combination of South Africa and Africa into a single region earlier this year, is consistent with my desire to focus key responsibilities in a smaller and more effective executive group. Combining legal, communications, regulatory affairs and sustainability into one integrated function under John Davidson, reporting directly to me, will serve our business better in a changing legal and regulatory environment. Aligning our investor relations activities more closely with our finance team under Jamie Wilson’s leadership is a logical development that will further enhance our engagement with financial stakeholders.

“I want to thank Catherine for her support over the past two years, in which she has continued to develop critical capabilities to help to grow our business sustainably for the benefit of all of our stakeholders. In particular, she has overseen the very successful launch earlier this year of Prosper, our new sustainable development ambition, delivered an excellent leadership engagement programme, and introduced a new corporate identity and digital presence for our business. I am very grateful for her contribution to the group.”
