The Asia Pacific-focused investment trust has appointed Matthews International Capital Management and MW GaveKal Asia.
Aberdeen Asset Managers will remain as a manager with responsibility for 55% of the portfolio.
Matthews International will manage around 35% of the trust’s assets and MW GaveKal approximately 10%.
San Francisco-based Matthews International currently manages $17.8 billion (£11.05 billion) in Asia Pacific bonds and equities.
MW GaveKal Asia is a joint venture between Marshall Waxe and GaveLal Holdings.
Gillian Nott, chairman of the Witan Pacific investment trust board says: “While making this change, the board would like to record its thanks to the managers at Nomura for their service to our shareholders in outperforming the benchmark index since 2005.
She adds: “In Aberdeen, Matthews and MW GaveKal we have a blend of strong managers with distinctive and successful records who will seek to deliver a well-diversified, balanced portfolio with an attractive mix of quality, growth and dividend yield.
“The appointment of Matthews, with its focus on dividend growth, is expected to increase the overall portfolio yield and with it the scope to support the trust’s dividend growth policy.
“The inclusion of MW GaveKal provides the potential to reduce the absolute volatility of the trust, particularly in down markets.”
