CI Mutual Funds Inc. on Tuesday announced that it is changing the allocation of underlying funds in the CI Portfolio Series funds, effective June 27.

The CI Portfolio Series is a group of asset allocation funds designed to provide an investor with an optimal portfolio – a diversified, style-neutral mix of funds producing the maximum return for a given level of risk.

Each CI Portfolio Fund invests in a carefully selected mix of up to 14 other CI mutual funds that vary by asset class, geographical mandate and investment style.

The changes were made with the assistance of Mercer Investment Consulting, the leading provider of investment consulting services to the fiduciaries of pension funds, foundations, endowments, and other institutional funds.

CI says these changes will make the CI Portfolio Funds more effective in meeting their objectives and do not change their overall investment objectives.

For a complete list of changes refer to the company’s news release.
