Toronto-based Invesco Canada Ltd. has received unitholder approval to merge Trimark North American Endeavour Class into Trimark U.S. Companies Class, the company announced on Tuesday.

The merger is expected to be effective after the close of business on Aug. 7.

In a separate vote, unitholders of Trimark Government Plus Income Fund approved changes to the fund’s investment objectives — to provide flexibility to invest a greater percentage of the gund’s assets in fixed-income securities issued by Canadian corporations, which had been limited to one-third of the fund’s assets.

As a result of this vote, the fund will be renamed Trimark Short-Term Income Fund. Both changes will be effective July 31.
