Investors Group Monday announced proposed changes to its fund offering involving eight fund mergers. Each of the mergers involves funds with similar investment mandates.

“The proposed mergers are intended to provide more effective management and, in some cases, broader more diversified investment mandates, which in turn, will provide the potential for more stable long-term performance,” the company said in a release.

The following proposed mergers are expected to take effect on Feb. 3, 2012:

All of the mergers have been reviewed by the IG Funds Independent Review Committee, which has determined that the mergers achieve a fair and reasonable result for the funds.

Securityholders of the merging funds, as well as for the two continuing class funds, will be asked to approve the mergers involving their funds at special meetings scheduled to be held Jan. 23, 2012, in Winnipeg.

The costs associated with the fund mergers will be borne by Investors Group.
