Weighted average maturity (WAM) is an average of the maturities of all securities held in the portfolio, weighted by each security’s percentage of net assets. The days to maturity for WAM is the lower of the stated maturity date or next interest rate reset date. WAM reflects how a portfolio would react to interest rate changes. Weighted average life (WAL) is an average of all the maturities of all securities held in the portfolio, weighted by each security’s percentage of net assets. The days to maturity for WAL is the lower of the stated maturity date or next demand feature date. WAL reflects how a portfolio would react to deteriorating credit (widening spreads) or tightening liquidity conditions.

35 Short-Term Investments Trust

Notes to Financial Statements

February 28, 2021

(Unaudited)

NOTE 1–Significant Accounting Policies

Short-Term Investments Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end series diversified management investment company. The Trust is organized as a Delaware statutory trust which currently offers six separate portfolios (each constituting a “Fund”). The Funds covered in this report are Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio, Invesco Treasury Portfolio, Invesco Government & Agency Portfolio, Invesco Treasury Obligations Portfolio and Invesco Tax-Free Cash Reserve Portfolio (collectively, the “Funds”). The assets, liabilities and operations of each Fund are accounted for separately. Information presented in these financial statements pertains only to the Funds. Matters affecting each Fund or class will be voted on exclusively by the shareholders of such Fund or class.

The investment objectives of the Funds are: to provide current income consistent with preservation of capital and liquidity for Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio, Invesco Treasury Portfolio, Invesco Government & Agency Portfolio and Invesco Treasury Obligations Portfolio; and to provide tax-exempt income consistent with preservation of capital and liquidity for Invesco Tax-Free Cash Reserve Portfolio.

Invesco Liquid Assets Portfolio, Invesco Treasury Portfolio and Invesco Government & Agency Portfolio currently offer eight different classes of shares: Institutional Class, Private Investment Class, Personal Investment Class, Cash Management Class, Reserve Class, Resource Class, Corporate Class and CAVU Securities Class. On December 18, 2020, Invesco Liquid Assets Portfolio, Invesco Treasury Portfolio and Invesco Government & Agency Portfolio began offering CAVU Securities class shares. Invesco STIC Prime Portfolio, Invesco Treasury Obligations Portfolio and Invesco Tax-Free Cash Reserve Portfolio currently offer seven different classes of shares: Institutional Class, Private Investment Class, Personal Investment Class, Cash Management Class, Reserve Class, Resource Class and Corporate Class.

Each Fund is an investment company and accordingly follows the investment company accounting and reporting guidance in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 946, Financial Services – Investment Companies.

Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, both institutional money market funds, price and transact in their shares at a floating net asset value (“NAV”) reflecting the current market-based values of their portfolio securities, except as otherwise generally permitted for securities with remaining maturities of 60 days or less, which are valued at amortized cost. Rules and regulations also require Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio to round their NAVs to four decimal places (e.g., $1.0000).

Invesco Liquid Assets Portfolio determines its NAV per share multiple times each day.

Invesco Treasury Portfolio, Invesco Government & Agency Portfolio and Invesco Treasury Obligations Portfolio, each a “government money market fund” as defined in Rule 2a-7 under the 1940 Act, and Invesco Tax-Free Cash Reserve Portfolio, a “retail money market fund” as defined in Rule 2a-7 under the 1940 Act, seek to maintain a stable or constant NAV of $1.00 per share using an amortized cost method of valuation.

“Government money market funds” are required to invest at least 99.5% of their total assets in cash, Government Securities (as defined in the 1940 Act), and/or repurchase agreements collateralized fully by cash or Government Securities. “Retail money market funds” are required to adopt policies and procedures reasonably designed to limit investments in the Fund to accounts beneficially owned by natural persons.

Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio and Invesco Tax-Free Cash Reserve Portfolio may impose a fee upon the sale of shares or may temporarily suspend the ability to sell shares if the Fund’s liquidity falls below required minimums or because of market conditions or other factors. The Board of Trustees has elected not to subject Invesco Treasury Portfolio, Invesco Government & Agency Portfolio and Invesco Treasury Obligations Portfolio to liquidity fee and redemption gate requirements at this time, as permitted by Rule 2a-7.

The following is a summary of the significant accounting policies followed by the Funds in the preparation of their financial statements.

Security Valuations - Invesco Liquid Assets Portfolio’s and Invesco STIC Prime Portfolio’s 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, market information from brokers and dealers, developments related to specific securities, yield (for debt obligations), quality, type of issue, coupon rate (for debt obligations), maturity (for debt obligations), individual trading characteristics and other market data. Pricing services generally value debt obligations assuming orderly transactions of institutional round lot size, but a fund may hold or transact in the same securities in smaller, odd lot sizes. Odd lots often trade at lower prices than institutional round lots. Debt obligations are subject to interest rate and credit risks. In addition, all debt obligations involve some risk of default with respect to interest and/or principal payments.

Securities for which market quotations are not readily available or became 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. Issuer specific events, market trends, bid/asked quotes of brokers and information providers and other market data may be reviewed in the course of making a good faith determination of a security’s fair value.

Invesco Treasury Portfolio, Invesco Government & Agency Portfolio, Invesco Treasury Obligations Portfolio and Invesco Tax-Free Cash Reserve Portfolio’s securities are recorded on the basis of amortized cost which approximates value as permitted by Rule 2a-7 under the 1940 Act. This method values a security at its cost on the date of purchase and, thereafter, assumes a constant amortization to maturity of any premiums or accretion of any discounts.

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.

Each Fund may invest in securities that are subject to interest rate risk, meaning the risk that the prices will generally fall as interest rates rise and, conversely, the prices will generally rise as interest rates fall. Specific securities differ in their sensitivity to changes in interest rates depending on their individual characteristics. Changes in interest rates may result in increased market volatility, which may affect the value and/or liquidity of certain of each Fund’s 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 (net of withholding tax, if any) is

36 Short-Term Investments Trust

recorded on the accrual basis from settlement date and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.

The Funds may periodically participate in litigation related to each Fund’s investments. As such, the Funds may receive proceeds from litigation settlements involving each Fund’s investments. Any proceeds received are included in the Statements 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 gain (loss) from investment securities reported in the Statements of Operations and the Statements of Changes in Net Assets and the net realized gains (losses) on securities per share in the Financial Highlights. Transaction costs are included in the calculation of each Fund’s net asset value and, accordingly, they reduce each Fund’s total returns. These transaction costs are not considered operating expenses and are not reflected in net investment income reported in the Statements of Operations and the Statements of Changes in Net Assets, or the net investment income per share and the ratios of expenses and net investment income reported in the Financial Highlights, nor are they limited by any expense limitation arrangements between the Funds and the investment adviser.

The Funds allocate realized capital gains and losses to a class based on the relative net assets of each class. The Funds allocate income to a class based on the relative value of the settled shares of each class.

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.

D.	Distributions - It is the policy of the Funds to declare dividends from net investment income daily and pay dividends on the first business day of the following month. Each Fund generally distributes net realized capital gain (including net short-term capital gain), if any, annually.

Federal Income Taxes - The Funds intend to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), necessary to qualify as a regulated investment company and to distribute substantially all of the Funds’ taxable earnings to shareholders. As such, the Funds will not be subject to federal income taxes on otherwise taxable income (including net realized capital gain) that is distributed to shareholders. Therefore, no provision for federal income taxes is recorded in the financial statements.

The Funds recognize the tax benefits of uncertain tax positions only when the position is more likely than not to be sustained. Management has analyzed each Fund’s uncertain tax positions and concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions. Management is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially in the next 12 months.

In addition, Invesco Tax-Free Cash Reserve Portfolio intends to invest in such municipal securities to allow it to qualify to pay shareholders “exempt interest dividends”, as defined in the Internal Revenue Code.

Each Fund files tax returns in the U.S. Federal jurisdiction and certain other jurisdictions. Generally, each Fund is subject to examinations by such taxing authorities for up to three years after the filing of the return for the tax period.

Expenses - Fees provided for under the Rule 12b-1 plan of a particular class of each Fund and which are directly attributable to that class are charged to the operations of such class. All other expenses of each respective Fund are allocated among the classes of such Fund based on relative net assets.

Accounting Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period including estimates and assumptions related to taxation. Actual results could differ from those estimates by a significant amount. In addition, each Fund monitors for material events or transactions that may occur or become known after the period-end date and before the date the financial statements are released to print.

Indemnifications - Under the Trust’s organizational documents, each Trustee, officer, employee or other agent of the Trust is indemnified against certain liabilities that may arise out of the performance of their duties to the Funds. Additionally, in the normal course of business, the Funds enter into contracts, including each Fund’s servicing agreements, that contain a variety of indemnification clauses. Each Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against such Fund that have not yet occurred. The risk of material loss as a result of such indemnification claims is considered remote.

Repurchase Agreements - The Funds may enter into repurchase agreements. Collateral on repurchase agreements, including each Fund’s pro-rata interest in joint repurchase agreements, is taken into possession by such Funds upon entering into the repurchase agreement. Collateral consisting of U.S. Government Securities and U.S. Government Sponsored Agency Securities is marked to market daily to ensure its market value is at least 102% of the sales price of the repurchase agreement. Collateral consisting of non-government securities is marked to market daily to ensure its market value is at least 105% of the sales price of the repurchase agreement. The investments in some repurchase agreements, pursuant to procedures approved by the Board of Trustees, are through participation with other mutual funds, private accounts and certain non-registered investment companies managed by the investment advisor or its affiliates (“Joint repurchase agreements”). The principal amount of the repurchase agreement is equal to the value at period-end. If the seller of a repurchase agreement fails to repurchase the security in accordance with the terms of the agreement, the Funds might incur expenses in enforcing their rights, and could experience losses, including a decline in the value of the collateral and loss of income.

37 Short-Term Investments Trust

cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to the Fund.

Other Risks – Investments in obligations issued by agencies and instrumentalities of the U.S. Government may vary in the level of support they receive from the government. The government may choose not to provide financial support to government sponsored agencies or instrumentalities if it is not legally obligated to do so. In this case, if the issuer defaulted, the Funds may not be able to recover its investment in such issuer from the U.S. Government.

The effect on performance from investing in securities issued or guaranteed by companies in the banking and financial services industries will depend to a greater extent on the overall condition of those industries. Financial services companies are highly dependent on the supply of short-term financing. The value of securities of issuers in the banking and financial services industry can be sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad.

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 each Fund’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.

U.S. dollar-denominated securities carrying foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect payments of principal and interest.

NOTE 2–Advisory Fees and Other Fees Paid to Affiliates

The Trust has entered into a master investment advisory agreement with Invesco Advisers, Inc. (the “Adviser” or “Invesco”). Under the terms of the investment advisory agreement, each Fund accrues daily and pays monthly an advisory fee to the Adviser at an annual rate based on each Funds’ average daily net assets as follows, respectively:

The fees are accrued daily and paid monthly. Of the Plan payments, up to 0.25% of the average daily net assets of each class of each Fund may be paid to furnish continuing personal shareholder services to customers who purchase and own shares of such class. Any amounts not paid as a service fee under such Plan would constitute an asset-based sales charge. Rules of the Financial Industry Regulatory Authority (“FINRA”), impose a cap on the total amount of sales charges, including asset-based sales charges, that may be paid by any class of shares of each Fund.

Certain officers and trustees of the Trust are officers and directors of the Adviser, IIS and/or IDI.

NOTE 3–Additional Valuation Information

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 each Fund’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.

As of February 28, 2021, all of the securities in each Fund were valued based on Level 2 inputs (see the Schedule of Investments for security categories). 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.

NOTE 4–Security Transactions with Affiliated Funds

Each Fund is permitted to purchase or sell securities from or to certain other Invesco Funds under specified conditions outlined in procedures adopted by the Board of Trustees of the Trust. The procedures have been designed to ensure that any purchase or sale of securities by each Fund from or to another fund or portfolio that is or could be considered an affiliate by virtue of having a common investment adviser (or affiliated investment advisers), common Trustees and/or common officers complies with Rule 17a-7 of the 1940 Act. Further, as defined under the procedures, each transaction is effected at the current market price. For the six months ended February 28, 2021, each Fund engaged in transactions with affiliates as listed below:


	Securities Purchases			Securities Sales			Net Realized Gains
Invesco Liquid Assets Portfolio		$	51,476,404		$	63,220,429		$	-
Invesco STIC Prime Portfolio			6,690,224			6,470,000			-
Invesco Tax-Free Cash Reserve Portfolio			60,797,279			79,468,553			-

NOTE 5–Trustees’ and Officers’ Fees and Benefits

Trustees’ and Officers’ Fees and Benefits include amounts accrued by each Fund to pay remuneration to certain Trustees and Officers of such Fund. Trustees have the option to defer compensation payable by the Funds, and Trustees’ and Officers’ Fees and Benefits also include amounts accrued by each Fund to fund such deferred compensation amounts. Those Trustees who defer compensation have the option to select various Invesco Funds in which their deferral accounts shall be deemed to be invested. Finally, certain current Trustees were eligible to participate in a retirement plan that provided for benefits to be paid upon retirement to Trustees over a period of time based on the number of years of service. The Funds may have certain former Trustees who also participate in a retirement plan and receive benefits under such plan. Trustees’ and Officers’ Fees and Benefits include amounts accrued by each Fund to fund such retirement benefits. Obligations under the deferred compensation and retirement plans represent unsecured claims against the general assets of the Funds.

NOTE 6–Cash Balances

The Funds are permitted to temporarily overdraft or leave balances in their accounts with BNY Mellon, the custodian bank. Such balances, if any at period-end, are shown in the Statements of Assets and Liabilities under the payable caption Amount due custodian. To compensate BNY Mellon or the Funds for such activity, the Funds may either (1) pay to or receive from BNY Mellon compensation at a rate agreed upon by BNY Mellon and Invesco, not to exceed the contractually agreed upon rate; or (2) leave funds or overdraft funds as a compensating balance in the account so BNY Mellon or the Funds can be compensated for use of funds.

NOTE 7–Tax Information

The amount and character of income and gains to be distributed are determined in accordance with income tax regulations, which may differ from GAAP. Reclassifications are made to each Fund’s capital accounts to reflect income and gains available for distribution (or available capital loss carryforward) under income tax regulations. The tax character of distributions paid during the year and the tax components of net assets will be reported at each Fund’s fiscal year-end.

Capital loss carryforward is calculated and reported as of a specific date. Results of transactions and other activity after that date may affect the amount of capital loss carryforward actually available for the Funds to utilize. The ability to utilize capital loss carryforwards in the future may be limited under the Internal Revenue Code and related regulations based on the results of future transactions.

The Funds had a capital loss carryforward as of August 31, 2020, as follows:


Fund	Not Subject to Expiration			Total*
Invesco Liquid Assets Portfolio		$	15,623		$	15,623
Invesco Government & Agency Portfolio			189,476			189,476
Invesco Treasury Obligations Portfolio			59,505			59,505
Invesco Tax-Free Cash Reserve Portfolio			19,092			19,092

*	Capital loss carryforwards are reduced for limitations, if any, to the extent required by the Internal Revenue Code and may be further limited depending upon a variety of factors, including the realization of net unrealized gains or losses as of the date of any reorganization.

NOTE 8–Investment Transactions

The aggregate cost and the net unrealized appreciation (depreciation) of investments for tax purposes are as follows:


	At February 28, 2021

There are entities that are record owners of more than 5% of the outstanding shares of the Fund and in the aggregate own 78% of the outstanding shares of the Fund. IDI has an agreement with these entities to sell Fund shares. The Fund, Invesco and/or Invesco affiliates may make payments to these entities, which are considered to be related to the Fund, for providing services to the Fund, Invesco and/or Invesco affiliates including but not limited to services such as securities brokerage, distribution, third party record keeping and account servicing.

NOTE 10–Coronavirus (COVID-19) Pandemic

During the first quarter of 2020, the World Health Organization declared COVID-19 to be a public health emergency. COVID-19 has led to increased short-term market volatility and may have adverse long-term effects on U.S. and world economies and markets in general. COVID-19 may adversely impact the Funds’ ability to achieve their investment objectives. Because of the uncertainties on valuation, the global economy and business operations, values reflected in these financial statements may materially differ from the value received upon actual sales of those investments.

The extent of the impact on the performance of the Funds and their investments will depend on future developments, including the duration and spread of the COVID-19 outbreak, related restrictions and advisories, and the effects on the financial markets and economy overall, all of which are highly uncertain and cannot be predicted.

Calculating your ongoing Fund expenses

Example

As a shareholder in the Institutional Class, you incur ongoing costs, such as management fees and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Funds and to compare these costs with ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period September 1, 2020 through February 28, 2021.

Actual expenses

The table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the table under the heading entitled “Actual Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The table below also provides information about hypothetical account values and hypothetical expenses based on each Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not each Fund’s actual return.

The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Funds and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only. Therefore, the hypothetical information is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds.

The actual ending account value is based on the actual total return of the Funds for the period September 1, 2020 through February 28, 2021, after actual expenses and will differ from the hypothetical ending account value which is based on each Fund’s expense ratio and a hypothetical annual return of 5% before expenses.

²	Expenses are equal to each Fund’s annualized expense ratio as indicated above multiplied by the average account value over the period, multiplied by 181/365 to reflect the most recent fiscal half year.

Notes to Financial Statements

February 28, 2021

(Unaudited)

NOTE 1—Significant Accounting Policies

Invesco Liquid Assets Portfolio determines its NAV per share multiple times each day.

The following is a summary of the significant accounting policies followed by the Funds in the preparation of their financial statements.

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 (net of withholding tax, if any) is

36 Short-Term Investments Trust

recorded on the accrual basis from settlement date and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.

D.	Distributions - It is the policy of the Funds to declare dividends from net investment income daily and pay dividends on the first business day of the following month. Each Fund generally distributes net realized capital gain (including net short-term capital gain), if any, annually.

37 Short-Term Investments Trust

Other Risks - Investments in obligations issued by agencies and instrumentalities of the U.S. Government may vary in the level of support they receive from the government. The government may choose not to provide financial support to government sponsored agencies or instrumentalities if it is not legally obligated to do so. In this case, if the issuer defaulted, the Funds may not be able to recover its investment in such issuer from the U.S. Government.

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 3—Additional Valuation Information

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 each Fund’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.

Example

As a shareholder in the Corporate Class, you incur ongoing costs, including management fees, distribution and/or service (12b-1) fees and other Fund expenses.

The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period September 1, 2020 through February 28, 2021.

NOTE 1—Significant Accounting Policies

Invesco Liquid Assets Portfolio determines its NAV per share multiple times each day.

The following is a summary of the significant accounting policies followed by the Funds in the preparation of their financial statements.

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 (net of withholding tax, if any) is

recorded on the accrual basis from settlement date and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.

D.	Distributions - It is the policy of the Funds to declare dividends from net investment income daily and pay dividends on the first business day of the following month. Each Fund generally distributes net realized capital gain (including net short-term capital gain), if any, annually.

37 Short-Term Investments Trust

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 1—Significant Accounting Policies

Invesco Liquid Assets Portfolio determines its NAV per share multiple times each day.

The following is a summary of the significant accounting policies followed by the Funds in the preparation of their financial statements.

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 (net of withholding tax, if any) is

recorded on the accrual basis from settlement date and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.

D.	Distributions - It is the policy of the Funds to declare dividends from net investment income daily and pay dividends on the first business day of the following month. Each Fund generally distributes net realized capital gain (including net short-term capital gain), if any, annually.

37 Short-Term Investments Trust

(Unaudited)

NOTE 1—Significant Accounting Policies

Invesco Liquid Assets Portfolio determines its NAV per share multiple times each day.

The following is a summary of the significant accounting policies followed by the Funds in the preparation of their financial statements.

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.

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 (net of withholding tax, if any) is

36	Short-Term Investments Trust

recorded on the accrual basis from settlement date and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.

Distributions - It is the policy of the Funds to declare dividends from net investment income daily and pay dividends on the first business day of the following month. Each Fund generally distributes net realized capital gain (including net short-term capital gain), if any, annually.

37	Short-Term Investments Trust

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.

The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period September 1, 2020 through February 28, 2021.

The days to maturity for WAM is the lower of the stated maturity date or next interest rate reset date. WAM reflects how a portfolio would react to interest rate changes.

Weighted average life (WAL) is an average of all the maturities of all securities held in the portfolio, weighted by each security’s percentage of net assets. The days to maturity for WAL is the lower of the stated maturity date or next demand feature date. WAL reflects how a portfolio would react to deteriorating credit (widening spreads) or tightening liquidity conditions.

Notes to Financial Statements

February 28, 2021 (Unaudited)

NOTE 1–Significant Accounting Policies

Invesco Liquid Assets Portfolio determines its NAV per share multiple times each day.

The following is a summary of the significant accounting policies followed by the Funds in the preparation of their financial statements.

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 (net of withholding tax, if any) is

recorded on the accrual basis from settlement date and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.

D.	Distributions - It is the policy of the Funds to declare dividends from net investment income daily and pay dividends on the first business day of the following month. Each Fund generally distributes net realized capital gain (including net short-term capital gain), if any, annually.

37 Short-Term Investments Trust

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.

Notes to Financial Statements

February 28, 2021

(Unaudited)

NOTE 1–Significant Accounting Policies

Short-Term Investments Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end series diversified management investment company. The Trust is organized as a Delaware statutory trust which currently offers six separate portfolios (each constituting a “Fund”). The Funds covered in this report are Invesco Liquid Assets Portfolio, Invesco Treasury Portfolio and Invesco Government & Agency Portfolio (collectively, the “Funds”). The assets, liabilities and operations of each Fund are accounted for separately. Information presented in these financial statements pertains only to the Funds. Matters affecting each Fund or class will be voted on exclusively by the shareholders of such Fund or class.

The investment objectives of the Funds are: to provide current income consistent with preservation of capital and liquidity for Invesco Liquid Assets Portfolio, Invesco Treasury Portfolio and Invesco Government & Agency Portfolio.

Each Fund currently offers eight different classes of shares: Institutional Class, Private Investment Class, Personal Investment Class, Cash Management Class, Reserve Class, Resource Class, Corporate Class and CAVU Securities Class. On December 18, 2020, Invesco Liquid Assets Portfolio, Invesco Treasury Portfolio and Invesco Government & Agency Portfolio began offering CAVU Securities class shares.

Invesco Liquid Assets Portfolio, an institutional money market fund, prices and transacts in its shares at a floating net asset value (“NAV”) reflecting the current market-based values of its portfolio securities, except as otherwise generally permitted for securities with remaining maturities of 60 days or less, which are valued at amortized cost. Rules and regulations also require Invesco Liquid Assets Portfolio to round its NAV to four decimal places (e.g., $1.0000).

Invesco Liquid Assets Portfolio determines its NAV per share multiple times each day.

Invesco Treasury Portfolio and Invesco Government & Agency Portfolio, each a “government money market fund” as defined in Rule 2a-7 under the 1940 Act, seek to maintain a stable or constant NAV of $1.00 per share using an amortized cost method of valuation.

Invesco Liquid Assets Portfolio may impose a fee upon the sale of shares or may temporarily suspend the ability to sell shares if the Fund’s liquidity falls below the required minimum or because of market conditions or other factors. The Board of Trustees has elected not to subject Invesco Treasury Portfolio and Invesco Government & Agency Portfolio to liquidity fee and redemption gate requirements at this time, as permitted by Rule 2a-7.

The following is a summary of the significant accounting policies followed by the Funds in the preparation of their financial statements.

Security Valuations - Invesco Liquid Assets Portfolio’s 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, market information from brokers and dealers, developments related to specific securities, yield (for debt obligations), quality, type of issue, coupon rate (for debt obligations), maturity (for debt obligations), individual trading characteristics and other market data. Pricing services generally value debt obligations assuming orderly transactions of institutional round lot size, but a fund may hold or transact in the same securities in smaller, odd lot sizes. Odd lots often trade at lower prices than institutional round lots. Debt obligations are subject to interest rate and credit risks. In addition, all debt obligations involve some risk of default with respect to interest and/or principal payments.

Invesco Treasury Portfolio and Invesco Government & Agency Portfolio’s securities are recorded on the basis of amortized cost which approximates value as permitted by Rule 2a-7 under the 1940 Act. This method values a security at its cost on the date of purchase and, thereafter, assumes a constant amortization to maturity of any premiums or accretion of any discounts.

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.

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 (net of withholding tax, if any) is recorded on the accrual basis from settlement date and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.

24 Short-Term Investments Trust

accordingly, they reduce each Fund’s total returns. These transaction costs are not considered operating expenses and are not reflected in net investment income reported in the Statements of Operations and the Statements of Changes in Net Assets, or the net investment income per share and the ratios of expenses and net investment income reported in the Financial Highlights, nor are they limited by any expense limitation arrangements between the Funds and the investment adviser.

D.	Distributions - It is the policy of the Funds to declare dividends from net investment income daily and pay dividends on the first business day of the following month. Each Fund generally distributes net realized capital gain (including net short-term capital gain), if any, annually.

LIBOR Risk - Certain Funds may invest in financial instruments that utilize LIBOR as the reference or benchmark rate for variable interest rate calculations. On July 27, 2017, the head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. Although many LIBOR rates will be phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition. There remains uncertainty regarding the effect of the LIBOR transition process and therefore any impact of a transition away from LIBOR on the Fund or the instruments in which the Fund invests cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to the Fund.

25 Short-Term Investments Trust

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 3–Additional Valuation Information


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 each Fund’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.

NOTE 5–Trustees’ and Officers’ Fees and Benefits

Trustees’ and Officers’ Fees and Benefits include amounts accrued by each Fund to pay remuneration to certain Trustees and Officers of such Fund. Trustees have the option to defer compensation payable by the Funds, and Trustees’ and Officers’ Fees and Benefits also include amounts accrued by each Fund to fund such deferred compensation amounts. Those Trustees who defer compensation have the option to select various Invesco Funds in which their deferral accounts shall be deemed to be invested. Finally, certain current Trustees were eligible to participate in a retirement plan that provided for benefits to be paid upon retirement to Trustees over a period of time based on the number of years of service. The Funds may have certain former Trustees who also participate in a retirement plan and receive benefits under such plan. Trustees’ and Officers’ Fees and Benefits include amounts accrued by each Fund to fund such retirement benefits. Obligations under the deferred compensation and retirement plans represent unsecured claims against the general assets of the Funds.

NOTE 6–Cash Balances

The Funds are permitted to temporarily overdraft or leave balances in their accounts with BNY Mellon, the custodian bank. Such balances, if any at period-end, are shown in the Statements of Assets and Liabilities under the payable caption Amount due custodian. To compensate BNY Mellon or the Funds for such activity, the Funds may either (1) pay to or receive from BNY Mellon compensation at a rate agreed upon by BNY Mellon and Invesco, not to exceed the contractually agreed upon rate; or (2) leave funds or overdraft funds as a compensating balance in the account so BNY Mellon or the Funds can be compensated for use of funds.

NOTE 7–Tax Information

NOTE 10–Coronavirus (COVID-19) Pandemic

31 Short-Term Investments Trust

Calculating your ongoing Fund expenses

Example

As a shareholder in the CAVU Securities Class, you incur ongoing costs, including management fees and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Funds and to compare these costs with ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period September 1, 2020 through February 28, 2021.

Actual expenses

Hypothetical example for comparison purposes


CAVU Securities Class	Beginning Account Value (09/01/20)			ACTUAL						HYPOTHETICAL (5% annual return before expenses)						Annualized Expense Ratio
CAVU Securities Class	Beginning Account Value (09/01/20)			Ending Account Value (02/28/21)¹			Expenses Paid During Period²			Ending Account Value (02/28/21)			Expenses Paid During Period³			Annualized Expense Ratio
Invesco Liquid Assets Portfolio		$	1,000.00		$	1,000.10		$	0.36		$	1,009.64		$	0.90		0.18	%
Invesco Treasury Portfolio			1,000.00			1,000.00			0.24			1,009.76			0.60		0.12
Invesco Government & Agency Portfolio			1,000.00			1,000.10			0.18			1,009.82			0.45		0.09

The actual ending account value is based on the actual total return of the Funds for the period December 18, 2020 (commencement of operations) through February 28, 2021, after actual expenses, and will differ from the hypothetical ending account value which is based on each Fund’s expense ratio and a hypothetical annual return of 5% before expenses.

Actual expenses are equal to each Fund’s annualized expense ratio as indicated above multiplied by the average account value over the period multiplied by 73 (as of close of business December 18, 2020 through February 28, 2021)/365. Because the CAVU Securities Class shares have not been in existence for a full six month period, the actual ending account value and expense information shown may not provide a meaningful comparison to fund expense information of classes that show such data for a full six month period and, because the actual ending account value and expense information in the expense example covers a short time period, return and expense data may not be indicative of return and expense data for longer time periods.

Hypothetical expenses are equal to the annualized expense ratio indicated above multiplied by the average account value over the period, multiplied by 181/365 to reflect a one-half year period. The hypothetical ending account value and expenses may be used to compare ongoing costs of investing in CAVU Securities Class shares of the Funds because such data is based on a full six month period.
