White & Case has appointed a new executive committee following its re-election of firmwide chair Hugh Verrier.

Verrier will begin his second term as firm chair when his current four-year term elapses in March 2012.

Brussels executive partner Jacquelyn MacLennan, Americas banking chief David Koschik and London managing partner Oliver Brettle (pictured) will join him at the helm of the firm, with all three also retaining their client-facing responsibilities.

Each partner has been handed a particular remit, with antitrust lawyer MacLennan set to focus on client relationship initiatives. She will also work closely with the firm's partnership in Asia to expand its practice in China as well as other high-growth markets in the Asia-Pacific region.

New York banking partner Koschik, meanwhile, will lead initiatives focused on increasing efficiency and innovation in client service delivery. He will also focus on growing the firm's New York office and strengthening its offering in Latin America.

White & Case's London chief Brettle, who was first appointed to the board in 2009, will focus on people development initiatives, while also overseeing growth in London and further integration throughout the EMEA region.

Verrier commented: "Over the past four years, we have put in place a global structure to better serve our clients. Now, the four of us will make sure we realise our strategic priorities: staying close to our clients, innovating our client service delivery and strengthening our one-firm culture."

It is understood that one of the conditions for Verrier's uncontested re-election earlier this year was an overhaul of the executive committee he had appointed at the beginning of his term in 2008.

At the time, the firm's partnership approved a raft of changes to the firm's management structure, including the appointment of an eight-strong partnership committee and a three-strong management committee selected by Verrier.
