The new board has been selected for the historic global funds management merger announced in October last year.
Following the completion of the merger between Henderson Group and Janus Capital, the new board will consist of chair Richard Gillingwater, deputy chair Glenn Schafer and non-executive directors Sarah Arkle, Kalpana Desai, Jeffrey Diermeier, Kevin Dolan, Eugene Flood Jr., Lawrence Kochard, Angela Seymour-Jackson and Tatsusaburo Yamamoto.
Henderson chief executive Andrew Formica and Janus chief executive Richard Weil will also join the board as co-chief executives.
Current Henderson directors Roger Thompson, Philip Wagstaff, Timothy How and Robert Jeens will resign from their board positions, but Thompson and Wagstaff will continue on in the combined entity as chief financial officer and global head of distribution respectively.
When the merger was announced, Formica said that the two groups are "well-aligned in terms of strategy, business mix and most importantly a culture of serving our clients by focusing on independent, active asset management."
"I look forward to working side-by-side with Dick as we create a company with the scale to serve more clients globally, as well as the strength to meet their future needs and the growing demands of our industry," he added.
Weil said: "The complementary nature of the two firms will facilitate a smooth integration and create an organisation with an expanded client-facing team and product suite, greater financial strength and enhanced talent, benefiting clients, shareholders and employees."
