The company said it plans to extend its no trail share class across its fund range by mid-2012 to fulfil a key requirement of RDR.
It began launching no trail share classes in May 2007, which took the AMC on some of its products to 1%, compared to a typical average AMC of 1.5% on its funds.
Invesco said its no trail share class would continue to pay rebates to platforms and other distributors.
It said the addition of the no trail share class to its gross distributing fixed income funds was a logical extension to the fund range and would ensure it was well positioned to support a variety of operating models in the post-RDR era.
