NOTE 1-SIGNIFICANT ACCOUNTING POLICIES
AIM Investment Securities Funds (the "Trust") is registered under the Investment Company Act of 1940, as
amended (the "1940 Act"), as an open-end series management investment company. The Trust is organized as a
Delaware business trust consisting of one portfolio, the Limited Maturity Treasury Portfolio (the "Fund"). The
investment objective of the Fund is to seek liquidity with minimum fluctuation in principal value and, consistent
with this investment objective, the highest total return achievable. The Fund currently offers two different classes
of shares: the AIM Limited Maturity Treasury Shares (the "AIM Shares") and the Institutional Shares. Matters
affecting each class are voted on exclusively by such shareholders.
The following is a summary of the significant accounting policies followed by the Fund in the preparation of its
financial statements. The preparation of financial statements in conformity with generally accepted accounting
principles requires management to make estimates and assumptions that affect the reported amounts of assets and
liabilities at the date of these financial statements and the reported amount of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
A. Security Valuations--Debt obligations that are issued or guaranteed by the U.S. Treasury are valued on the
basis of prices provided by an independent pricing service. Prices provided by the pricing service may be
determined without exclusive reliance on quoted prices, and may reflect appropriate factors such as yield, type of
issue, coupon rate and maturity date. Securities for which market prices are not provided by the pricing service
are valued at the mean between last bid and asked prices based upon quotes furnished by independent sources.
Securities for which market quotations are not readily available or are questionable are valued at fair value as
determined in good faith
