AIM Trimark Investments today announced that it is putting forth proposals at the upcoming annual and special meetings of the shareholders of AIM Trimark Corporate Class Inc. and AIM Trimark Canada Fund Inc. scheduled in late July.

AIM Trimark seeks to add certain of its tax-efficient flexible distribution series (T-FLEX) to Trimark Diversified Income Class and Trimark Monthly Income Private Pool. AIM Trimark will be proposing to re-designate the existing Series A and F shares of Trimark Monthly Income Private Pool and Trimark Diversified Income Class to Series T6 and F6 shares for Trimark Monthly Income Private Pool and Series T8 and F8 shares for Trimark Diversified Income Class.

T-FLEX provides a steady monthly cash flow and, depending on the fund, flexibility to choose from up to three target annual distribution levels (4%, 6% or 8%). T-FLEX also provides tax efficiency through tax-deferred distributions as well as by allowing switches between series in T-FLEX (within the same fund) and among funds within each respective corporate structure, with no immediate tax implications. In conjunction with introducing certain T-FLEX series for Trimark Diversified Income Class and Trimark Monthly Income Private Pool, AIM Trimark is seeking investor approval at the annual and special meetings to make minor amendments to the investment objectives of Trimark Diversified Income Class and Trimark Monthly Income Private Pool.

“As more and more investors enter retirement, the demand for investment solutions that provide tax-efficient cash flow will grow, and we’re delivering on these needs,” said Philip Taylor, AMVESCAP Senior Managing Director and head of AMVESCAP’s North American business, including AIM Trimark.

AIM Trimark also seeks investor approval to amend the investment objectives and fund name of AIM American Mid Cap Growth Class to reposition the fund to a North American equity mandate from a U.S. small-/mid-cap equity offering. If approved, the proposed changes will result in a broader mandate that may improve the risk-adjusted return potential of the fund.

Details of these proposals will be provided to investors in a management information circular and proxy package that will be mailed in late June 2007. These proposals require investor approval at the annual and special meetings of shareholders of AIM Trimark Canada Fund Inc. and AIM Trimark Corporate Class Inc. scheduled for July 31 in Toronto.
