Toronto-based CI Investments Inc. on Thursday announced risk rating changes for 24 of its mutual funds.

The changes are effective immediately.

The changes are based on the methodology mandated by the Canadian Securities Administrators to determine the risk level of mutual funds. CI reviews the risk rating for each fund at a minimum on an annual basis, as well as when a fund undergoes a material change.

“These changes are the result of an annual review, and are not results of any changes to the investment objectives, strategies or management of the funds,” CI says in a news release.

Details of the changes can be found in the company’s news release.
