                              ASREIF CONVERSION Q&A

For Internal Use Only

1.WHAT ARE THE REASONS FOR CONVERTING THE ASREIF FROM A CLOSED END TO AN OPEN
ENDED FUND?

     AIM believes that reorganizing your Fund as an open-end fund (the Buying
Fund) will immediately eliminate your Fund's trading discount at the time the
Reorganization occurs. Furthermore, AIM believes that your Fund's public
announcements on August 1, 2006 and September 19, 2006 already have provided
holders of your Fund's Common Shares with a return benefit as the price of the
Common Shares has increased towards their net asset value. Finally, AIM believes
that the opportunity to open-end your Fund on the terms and schedule that AIM
has established and that the Board has approved, and at AIM's own initiative, is
in the best interests of your Fund and the holders of its Common Shares.

     In addition, AIM believes that there is investor demand for an open-end
fund with the Buying Fund's investment objectives and strategies and is
proposing that your Fund be reorganized as an open-end fund to meet that
investor demand. AIM believes that the Buying Fund could be successfully
marketed as an open-end fund over the long term, although no assurance can be
given in this regard.

3. WHAT ASPECTS OF THE FUND WILL CHANGE AND WHAT WILL REMAIN THE SAME?

5. ARE THERE REDEMPTION FEES FOR CLIENTS WHO WISH TO EXIT THE FUND AFTER THE
CONVERSION?

The Buying Fund will be subject to a temporary 2.00% redemption fee applicable
to any of its Class A shares received in connection with the Reorganization that
are redeemed, including redemptions by exchange, during the 12 month period
following the closing date of the Reorganization. The redemption fee would not
apply to Class A shares of the Buying Fund that were purchased after the closing
date of the Reorganization. The redemption fee is to be retained by the Buying
Fund to offset transaction costs and other expenses associated with redemptions
or exchanges.

6. HOW DO YOUR FUND'S FEES AND EXPENSES COMPARE TO THE BUYING FUND'S FEES AND
EXPENSES

commenced operations), based on historical data of your Fund and related
projected data for the Class A shares of the Buying Fund after giving effect to
the Reorganization. There is no guarantee that actual expenses will be the same
as those shown in this table.

7. WHAT IS THE DIVIDEND POLICY FOR THE NEW OPEN ENDED STRUCTURE?

The fund will declare dividends quarterly and pay dividends quarterly.

8. WHAT IS THE BUYING FUND'S CLASS STRUCTURE AND WHICH CLASS OF BUYING FUND
SHARES WILL I RECEIVE IN THE REORGANIZATION

     The Buying Fund will offer Class A, Class B, Class C and Institutional
Class shares. Your Fund has only one class of shares (Common Shares)
outstanding. Class A shares of the Buying Fund will have rights that are
identical to the Class A shares of the other retail investment companies that
have AIM as an investment advisor (the "AIM Funds"). AIM believes that
introducing these additional share classes of the Buying Fund will facilitate
new purchases after the Reorganization.

     Holders of your Fund's Common Shares will receive Class A shares of the
Buying Fund upon the Reorganization. As a result, the only class of shares of
the Buying Fund described in this Proxy Statement/Prospectus are Class A shares.

9. HOW AND WHEN WILL THE REORGANIZATION OCCUR

     Consummation of the Reorganization (the "Closing") is expected to occur on
March 12, 2007 (the "Effective Time"). At the Effective Time, all of the assets
of your Fund will be delivered to the Buyer's



custodian for the account of the Buying Fund in exchange for the assumption by
the Buying Fund of the liabilities of your Fund and delivery by the Buyer to
your Fund (for distribution to shareholders) of a number of Class A shares of
the Buying Fund equal to the number of Common Shares of your Fund, (including,
if applicable, fractional shares rounded to the nearest thousandth), determined
and adjusted as provided in the Agreement. Upon delivery of such assets, the
Buying Fund will receive good and marketable title to such assets free and clear
of all liens.

     The Buying Fund will proceed with the Reorganization if the shareholders of
your Fund approve the Agreement.

     Following receipt of the requisite shareholder vote and as soon as
reasonably practicable after the Closing, the status of your Fund as a
designated series of the Trust will be terminated in accordance with the Trust's
Second Amended and Restated Agreement and Declaration of Trust and Amended and
Restated Bylaws and the Delaware Statutory Trust Act.

10. HOW DO I VOTE?

WHEN AND WHERE WILL THE SPECIAL MEETING BE HELD

     We are holding the Special Meeting at 11 Greenway Plaza, Suite 100,

     Your proxy will have the authority to vote and act on your behalf at any
adjournment of the Special Meeting.

exercised by sending in another proxy card with a later date or by notifying the
Secretary of the Trust in writing to the address of the Trust set forth on the
cover page of this Proxy Statement/Prospectus before the Special Meeting that
you have revoked your proxy. In addition, although merely attending the Special
Meeting will not revoke your proxy, if you are present at the Special Meeting
you may withdraw your proxy and vote in person. Shareholders may also transact
any other business not currently contemplated that may properly come before the
Special Meeting in the discretion of the proxies or their substitutes.
