Notes to Quarterly Schedule of Portfolio Holdings
May 31, 2011
(Unaudited)
May 31, 2011
(Unaudited)
NOTE 1 — Significant Accounting Policies
| A. | Security Valuations — Securities, including restricted securities, are valued according to the following policy. |
Securities are fair valued using an evaluated quote provided by an independent pricing
service approved by the Board of Trustees. Evaluated quotes provided by the pricing service may
be determined without exclusive reliance on quoted prices and may reflect appropriate factors
such as institution-size trading in similar groups of securities, yield, quality, coupon rate,
maturity, type of issue, individual trading characteristics and other market data. Short-term
obligations, including commercial paper, having 60 days or less to maturity are recorded at
amortized cost which approximates value. Securities with a demand feature exercisable within
one to seven days are valued at par. Debt securities are subject to interest rate and credit
risks. In addition, all debt securities involve some risk of default with respect to interest
and principal payments.
Securities for which market quotations either are not readily available or are unreliable
are valued at fair value as determined in good faith by or under the supervision of the Trust’s
officers following procedures approved by the Board of Trustees. Some of the factors which may
be considered in determining fair value are fundamental analytical data relating to the
investment; the nature and duration of any restrictions on transferability or disposition;
trading in similar securities by the same issuer or comparable companies; relevant political,
economic or issuer specific news; and other relevant factors under the circumstances.
Valuations change in response to many factors including the historical and prospective
earnings of the issuer, the value of the issuer’s assets, general economic conditions, interest
rates, investor perceptions and market liquidity. Because of the inherent uncertainties of
valuation, the values reflected in the financial statements may materially differ from the value
received upon actual sale of those investments.
| B. | Securities Transactions and Investment Income — Securities transactions are accounted for on a trade date basis. Realized gains or losses on sales are computed on the basis of specific identification of the securities sold. Interest income is recorded on the accrual basis from settlement date. Dividend income (net of withholding tax, if any) is recorded on the ex-dividend date. Bond premiums and discounts are amortized and/or accreted for financial reporting purposes. |
The Trust may periodically participate in litigation related to Trust investments. As
such, the Trust may receive proceeds from litigation settlements. Any proceeds received are
included in the Statement of Operations as realized gain (loss) for investments no longer held
and as unrealized gain (loss) for investments still held.
Brokerage commissions and mark ups are considered transaction costs and are recorded as an
increase to the cost basis of securities purchased and/or a reduction of proceeds on a sale of
securities. Such transaction costs are included in the determination of net realized and
unrealized gain (loss) from investment securities reported in the Statement of Operations and
the Statement of Changes in Net Assets and the net realized and unrealized gains (losses) on
securities per share in the Financial Highlights. Transaction costs are included in the
calculation of the Trust’s net asset value and, accordingly, they reduce the Trust’s total
returns. These transaction costs are not considered operating expenses and are not reflected in
net investment income reported in the Statement of Operations and Statement of Changes in Net
Assets, or the net investment income per share and ratios of expenses and net investment income
reported in the Financial Highlights, nor are they limited by any expense limitation
arrangements between the Trust and the investment adviser.
| C. | Country Determination — For the purposes of making investment selection decisions and presentation in the Schedule of Investments, the investment adviser may determine the country in which an issuer is located and/or credit risk exposure based on various factors. These factors include the laws of the country under which the issuer is organized, where the issuer maintains a principal office, the country in which the issuer derives 50% or more of its total revenues and the country that has the primary market for the issuer’s securities, as well as other criteria. Among the other criteria that may be evaluated for making this determination are the country in which the issuer maintains 50% or more of its assets, the type of security, financial guarantees and enhancements, the nature of the collateral and the sponsor organization. Country of issuer and/or credit risk exposure has been determined to be the United States of America, unless otherwise noted. |
Invesco Insured Municipal Income Trust
| D. | Floating Rate Note Obligations — The Trust invests in inverse floating rate securities, such as Residual Interest Bonds (“RIBs”) or Tender Option Bonds (“TOBs”) for investment purposes and to enhance the yield of the Trust. Inverse floating rate investments tend to underperform the market for fixed rate bonds in a rising interest rate environment, but tend to outperform the market for fixed rate bonds when interest rates decline or remain relatively stable. Such transactions may be purchased in the secondary market without first owning the underlying bond or by the sale of fixed rate bonds by the Trust to special purpose trusts established by a broker dealer (“Dealer Trusts”) in exchange for cash and residual interests in the Dealer Trusts’ assets and cash flows, which are in the form of inverse floating rate securities. The Dealer Trusts finance the purchases of the fixed rate bonds by issuing floating rate notes to third parties and allowing the Trust to retain residual interest in the bonds. The floating rate notes issued by the Dealer Trusts have interest rates that reset weekly and the floating rate note holders have the option to tender their notes to the Dealer Trusts for redemption at par at each reset date. The residual interests held by the Trust (inverse floating rate investments) include the right of the Trust (1) to cause the holders of the floating rate notes to tender their notes at par at the next interest rate reset date, and (2) to transfer the municipal bond from the Dealer Trusts to the Trust, thereby collapsing the Dealer Trusts. |
TOBs are presently classified as private placement securities.
Private placement securities are subject to restrictions on resale
because they have not been registered under the Securities Act of
1933, as amended or are otherwise not readily marketable. As a
result of the absence of a public trading market for these
securities, they may be less liquid than publicly traded
securities. Although these securities may be resold in privately
negotiated transactions, the prices realized from these sales
could be less than those originally paid by the Trust or less than
what may be considered the fair value of such securities.
The Trust accounts for the transfer of bonds to the Dealer Trusts as secured borrowings,
with the securities transferred remaining in the Trust’s investment assets, and the related
floating rate notes reflected as Trust liabilities under the caption Floating rate note
obligations on the Statement of Assets and Liabilities. The Trust records the interest income
from the fixed rate bonds under the caption Interest and records the expenses related to
floating rate obligations and any administrative expenses of the Dealer Trusts a component of
Interest, facilities and maintenance fees on the Statement of Operations.
The Trust generally invests in inverse floating rate securities that include embedded
leverage, thus exposing the Trust to greater risks and increased costs. The primary risks
associated with inverse floating rate securities are varying degrees of liquidity and the
changes in the value of such securities in response to changes in market rates of interest to a
greater extent than the value of an equal principal amount of a fixed rate security having
similar credit quality, redemption provisions and maturity which may cause the Trust’s net asset
value to be more volatile than if it had not invested in inverse floating rate securities. In
certain instances, the short-term floating rate interests created by the special purpose trust
may not be able to be sold to third parties or, in the case of holders tendering (or putting)
such interests for repayment of principal, may not be able to be remarketed to third parties. In
such cases, the special purpose trust holding the long-term fixed rate bonds may be collapsed.
In the case of RIBs or TOBs created by the contribution of long-term fixed income bonds by the
Trust, the Trust will then be required to repay the principal amount of the tendered securities.
During times of market volatility, illiquidity or uncertainty, the Trust could be required to
sell other portfolio holdings at a disadvantageous time to raise cash to meet that obligation.
| E. | Other Risks — The value of, payment of interest on, repayment of principal for and the ability to sell a municipal security may be affected by constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives and the economics of the regions in which the issuers are located. |
Since, many municipal securities are issued to finance similar projects, especially those
relating to education, health care, transportation and utilities, conditions in those sectors
can affect the overall municipal securities market and a Trust’s investments in municipal
securities.
There is some risk that a portion or all of the interest received from certain tax-free
municipal securities could become taxable as a result of determinations by the Internal Revenue
Service.

NOTE 2 — Additional Valuation Information
Generally Accepted Accounting Principles (“GAAP”) defines fair value as the price
that would be received to sell an asset or paid to transfer a liability in an orderly transaction
between market participants at the measurement date, under current market conditions. GAAP
establishes a hierarchy that prioritizes the inputs to valuation methods giving the highest
priority to readily available unadjusted quoted prices in an active market for identical assets
(Level 1) and the lowest priority to significant unobservable inputs (Level 3) generally when
market prices are not readily available or are unreliable. Based on the valuation inputs, the
securities or other investments are tiered into one of three levels. Changes in valuation methods
may result in transfers in or out of an investment’s assigned level:
| Level 1 | — | Prices are determined using quoted prices in an active market for identical assets. | ||||
| Level 2 | — | Prices are determined using other significant observable inputs. Observable inputs are inputs that other market participants may use in pricing a security. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, yield curves, loss severities, default rates, discount rates, volatilities and others. | ||||
| Level 3 | — | Prices are determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs reflect the Trust’s own assumptions about the factors market participants would use in determining fair value of the securities or instruments and would be based on the best available information. |
The following is a summary of the tiered valuation input levels, as of May 31, 2011. The
level assigned to the securities valuations may not be an indication of the risk or liquidity
associated with investing in those securities. Because of the inherent uncertainties of valuation,
the values reflected in the financial statements may materially differ from the value received upon
actual sale of those investments.
During the three months ended May 31, 2011, there were no significant transfers between
investment levels.
