BMO Investments Inc. Tuesday announced changes to the management expense ratio (MER) of the four BMO Guardian ETF Portfolio Class Series F funds.

As of December 1, BMO simplified the approach to determining the F class MER. Going forward, the MER will be capped at 100 basis points less than the current MER of the standard advisor series version.

BMO says this change in MER ensures BMO Guardian ETF Portfolios remain one of the lowest cost managed solution programs in the Canadian marketplace, and should appeal to advisors with clients in fee-based programs.
