The move, which is subject to shareholder approval, will see the newly merged fund focus on larger companies under the management of Andrew Shard.
The US range has been a thorn in Invesco Perpetual’s side in recent times.
All three funds are fourth quartile over three years in their IMA sectors and their underperformance was noted by Bestinvest’s recent Spot the Dog survey which highlights funds that have failed to beat their benchmark index in each of the past three years and underperformed their index by 10 per cent over that time.
Manager Ian Brady left the company in December 2007 and was replaced by Shard in February this year.
Invesco Perpetual chief executive and chief investment officer Bob Yerbury says: “Invesco Perpetual first launched a US equity fund in September 1983 and as a group we have over 25 years experience in managing US equities from Henley. In focusing our investment expertise into a single broad-cap US equity fund and with the recent appointment of Andrew Shard, we are taking the necessary steps to reinvigorate our US equity business.”
The changes are expected to take place on May 23.
