This report has been prepared for the general information of Northern Institutional Funds shareholders.

Investors are reminded to read a summary prospectus or prospectus carefully before investing or sending money.

You could lose money by investing in the Portfolios. Although each Portfolio seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so.

An investment in a Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”), any other government agency, or The Northern Trust Company, its affiliates, subsidiaries or any other bank. The Portfolios’ sponsor has no legal obligation to provide financial support to the Portfolios, and you should not expect that the sponsor will provide financial support to the Portfolios at any time.

Figures in the above table may not sum to 100% due to the exclusion of other assets and liabilities.

Various inputs are used in determining the value of the Portfolio’s investments.

These inputs are summarized in three levels listed below:

Level 1 – Unadjusted quoted market prices in active markets for identical securities on the measurement date.

Level 2 – Other observable inputs (e.g., quoted prices in active markets for similar securities, securities valuations based on commonly quoted benchmark interest rates and yield curves, maturities, ratings and/or securities indices).

Level 3 – Significant unobservable inputs (e.g., information about assumptions, including risk, market participants would use in pricing a security).

The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities and other financial instruments, if any. The following table summarizes the valuations of the Portfolio’s investments, which are carried at amortized cost, or at cost for repurchase agreements, which approximates fair value, by the above fair value hierarchy as of May 31, 2021:

MONEY MARKET PORTFOLIOS		24		NORTHERN INSTITUTIONAL FUNDS SEMIANNUAL REPORT

MONEY MARKET PORTFOLIOS

NOTES TO THE FINANCIAL STATEMENTS

MAY 31, 2021 (UNAUDITED)

1. ORGANIZATION

Northern Institutional Funds (the “Trust”) is a Delaware statutory trust and is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Trust includes 5 portfolios as of May 31, 2021, each with its own investment objective (e.g., income consistent with preservation of capital).

Northern Trust Investments, Inc. (“NTI”), an indirect subsidiary of Northern Trust Corporation, serves as the investment adviser for all of the portfolios. The Northern Trust Company (“Northern Trust”), an affiliate of NTI, serves as transfer agent, custodian and sub-administrator to the portfolios. Northern Funds Distributors, LLC, not an affiliate of NTI, is the Trust’s distributor.

Presented herein are the financial statements for the following three money market portfolios: Treasury Portfolio, U.S. Government Portfolio and U.S. Government Select Portfolio (each a “Portfolio” and collectively, the “Portfolios”). Each of these diversified Portfolios is authorized to issue the following three classes of shares: Shares, Service Shares and Premier Shares. The U.S. Government Select Portfolio is authorized to issue a fourth class of shares: Siebert Williams Shank Shares (formerly known as Williams Capital Shares). Each class is distinguished by the level of administrative and liaison services provided. At May 31, 2021, each of the Portfolios had Shares outstanding; the U.S. Government Portfolio and U.S. Government Select Portfolio had Service Shares outstanding; the Treasury Portfolio had Premier Shares outstanding; and the U.S. Government Select Portfolio had Siebert Williams Shank Shares outstanding. Premier Shares are currently only offered for the Treasury Portfolio.

Each Portfolio operates as a “government money market fund” under Rule 2a-7 of the 1940 Act.

2. SIGNIFICANT ACCOUNTING POLICIES

The Trust, which is an investment company, follows accounting and reporting guidance under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, Financial Services-Investment Companies.

The following is a summary of significant accounting policies consistently followed by the Portfolios in the preparation of their financial statements. These policies are in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.

A) VALUATION OF SECURITIES Investments held by the Portfolios are currently valued at amortized cost, which generally approximates fair value. Under this method, investments purchased at a discount or premium are valued by accreting or amortizing the difference between the original purchase price and maturity value of the issue over the period to effective maturity. If NTI has determined that amortized cost does not approximate fair value, such securities are fair valued in accordance with policies and procedures established by, and subject to oversight of, the Trust’s Board of Trustees (the “Board”).

The use of fair valuation involves the risk that the values used by the Portfolios to price their investments may be higher or lower than the values used by other unaffiliated investment companies and investors to price the same investments.

B) CASH AND CASH EQUIVALENTS Cash and cash equivalents may include cash and cash held in an interest-bearing deposit account at Northern Trust.

C) REPURCHASE AGREEMENTS The Portfolios may enter into repurchase agreements under the terms of a master repurchase agreement by which the Portfolios purchase securities for cash from a seller and agree to resell those securities to the same seller at a specific price within a specified time or with an indefinite life and liquidity feature, which allows the Portfolios to resell the securities quarterly. The interest rate on such repurchase agreements resets daily. During the term of a repurchase agreement, the fair value of the underlying collateral, including accrued interest, is required to equal or exceed the fair value of the repurchase agreement. The underlying collateral for tri-party repurchase agreements is held in accounts for Northern Trust or NTI (and is not reflected in the assets of the Portfolios) as agent of the Portfolios, at The Bank of New York Mellon, State Street Bank and Trust Company or JPMorgan Chase which, in turn, holds securities through the book-entry system at the Federal Reserve Bank of New York. The underlying collateral for other repurchase agreements is held in a customer-only account for Northern Trust, as custodian for the Portfolios, at the Federal Reserve Bank of Chicago. The Portfolios are subject to credit risk on repurchase agreements to the extent that the counterparty fails to perform under the agreement and the value of the collateral received falls below the agreed repurchase price. If the seller defaults and the value of the collateral declines or if bankruptcy proceedings are commenced with respect to the seller of the security, realization of collateral by the Portfolios may be delayed or limited. Certain Portfolios have entered into such repurchase agreements, as reflected in their accompanying Schedules of Investments, as of May 31, 2021.

Pursuant to exemptive relief granted by the U.S. Securities and Exchange Commission (“SEC”), the Treasury Portfolio, U.S. Government Portfolio and certain other money market portfolios advised by NTI and Northern Trust may enter into joint repurchase agreements with non-affiliated counterparties through a master repurchase agreement. NTI administers and manages


NORTHERN INSTITUTIONAL FUNDS SEMIANNUAL REPORT		25		MONEY MARKET PORTFOLIOS

MONEY MARKET PORTFOLIOS

NOTES TO THE FINANCIAL STATEMENTS continued

these joint repurchase agreements in accordance with and as part of its duties under its management agreement with the Portfolios and does not collect any additional fees from the Portfolios for such services. The Treasury Portfolio and U.S. Government Portfolio entered into such joint repurchase agreements during the period. There were no outstanding joint repurchase agreements at May 31, 2021.

The Portfolios may enter into transactions subject to enforceable netting arrangements (“Netting Arrangements”) under a repurchase agreement. Generally, Netting Arrangements allow the Portfolios to offset any exposure to a specific counterparty with any collateral received from or delivered to that counterparty. In addition, Netting Arrangements provide the right for the non-defaulting party to liquidate the collateral and calculate the net exposure to the defaulting party or request additional collateral. Generally, the Portfolios manage their cash collateral and securities collateral on a counterparty basis. As of May 31, 2021, the Portfolios were not invested in any portfolio securities other than the repurchase agreements described below, with gross exposures on the Statements of Assets and Liabilities, that could be netted subject to Netting Arrangements.

The following table presents the repurchase agreements, which are subject to Netting Arrangements, as well as the collateral delivered related to those repurchase agreements.

*	Collateral received is reflected up to the fair value of the repurchase agreement. Refer to the Schedules of Investments.

D) INVESTMENT TRANSACTIONS AND INCOME Investment transactions are recorded as of the trade date. The Portfolios determine the gain or loss realized from investment transactions by using an identified cost basis method. Interest income, if any, is recognized on an accrual basis and includes amortization of premiums and accretion of discounts. Certain Portfolios may receive dividend income from investment companies. Dividend income, if any, is recognized on the ex-dividend date.

E) EXPENSES Each Portfolio is charged for those expenses that are directly attributable to the Portfolio. Certain expenses arising in connection with a class of shares are charged to that class of shares. Expenses incurred that do not specifically relate to an individual Portfolio generally are allocated among all the portfolios in the Trust in proportion to each portfolio’s relative net assets. Expenses are recognized on an accrual basis.

F) DISTRIBUTIONS TO SHAREHOLDERS Distribution of dividends from net investment income are declared daily and paid monthly. Distributions of net realized capital gains, if any, are declared and paid at least annually. Distributions to shareholders are recorded on the ex-dividend date.

The timing and character of distributions determined in accordance with federal income tax regulations may differ from financial statement amounts determined in accordance with U.S. GAAP due to differences in the treatment and recognition of investment income and realized gains and losses. These differences are primarily related to the capital loss carryforwards. Inherent differences in the recognition of income and capital gains for federal income tax purposes, which are permanent, may result in periodic reclassifications in the Portfolios’ capital accounts. These reclassifications may relate to net operating losses and distribution reclassifications. These reclassifications have no impact on the net assets or the NAVs per share of the Portfolios.

At November 30, 2020, the following reclassifications were recorded:


Amounts in thousands	UNDISTRIBUTED NET INVESTMENT INCOME (LOSS)		ACCUMULATED UNDISTRIBUTED NET REALIZED GAINS (LOSSES)
Treasury		$1,047		$(1,047	)
U.S. Government		144		(144	)
U.S. Government Select		257		(257	)

G) FEDERAL INCOME TAXES No provision for federal income taxes has been made since each Portfolio’s policy is to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), applicable to regulated investment companies and to distribute, each year, substantially all of its taxable income and tax-exempt income to its shareholders.

The Regulated Investment Company Modernization Act of 2010 (the “Act”) allows capital losses to be carried forward for an unlimited period and to retain their character as either short-term or long-term. The Portfolios’ ability to utilize capital loss carryforwards in the future may be limited under the Code and related regulations based on the results of future transactions.

As of November 30, 2020, no Portfolio had uncertain tax positions that would require financial statement recognition or disclosure. The Portfolios’ federal tax returns remain subject to examination by the Internal Revenue Service for three years after they are filed. Any interest or penalties incurred, if any, on future unknown, uncertain tax positions taken by the Portfolios will be recorded as Interest expense and Other expenses, respectively, on the Statements of Operations.

3. BANK BORROWINGS

The Trust and the Northern Funds, a registered investment company also advised by NTI, jointly entered into a $250,000,000 senior unsecured revolving credit facility on November 16, 2020, which is administered by Citibank, N.A., for liquidity and other purposes (the “Credit Facility”). The interest rate charged under the Credit Facility is equal to the sum of (i) the Federal Funds Rate plus (ii) if the one month London Interbank Offered Rate (“LIBOR”) on the date of borrowing exceeded such Federal Funds Rate, the amount by which it so exceeded, plus (iii) 1.25 percent. In addition, there is an annual commitment fee of 0.15 percent on the unused portion of the credit line under the Credit Facility, payable quarterly in arrears, which is included in Other expenses on the Statements of Operations. The Credit Facility will expire on November 15, 2021, unless renewed.

The Portfolios did not have any borrowings or incur any interest expense for the six months ended May 31, 2021. There were no outstanding loan amounts at May 31, 2021.

4. MANAGEMENT AND OTHER AGREEMENTS

As compensation for advisory and administration services and the assumption of related expenses, NTI is entitled to a management fee, computed daily and payable monthly, at the annual rates set forth in the table below (expressed as a percentage of each Portfolio’s average daily net assets).

NTI has contractually agreed to reimburse a portion of the operating expenses of each Portfolio (other than certain excepted expenses, i.e., acquired fund fees and expenses, service fees, the compensation paid to each independent Trustee of the Trust, expenses of third-party consultants engaged by the Board, membership dues paid to the Investment Company Institute and Mutual Fund Directors Forum, expenses in connection with the negotiation and renewal of the revolving credit facility, extraordinary expenses and interest) as shown on the accompanying Statements of Operations, to the extent the total annual portfolio operating expenses exceed the expense limitations set forth below. The total annual portfolio operating expenses after expense reimbursement for each Portfolio may be higher than the contractual limitation as a result of certain excepted expenses that are not reimbursed. The amount of the reimbursement is included in Less expenses reimbursed by investment adviser as a reduction to Total Expenses in the Statements of Operations. The contractual expense reimbursement receivables at May 31, 2021 were approximately $129,000, $15,000 and $37,000 for the Treasury, U.S. Government and U.S. Government Select Portfolios, respectively, and are shown as part of Receivable from affiliates for expense reimbursements in the Statements of Assets and Liabilities. Any such reimbursement is paid monthly to the Portfolios by NTI.


MONEY MARKET PORTFOLIOS		28		NORTHERN INSTITUTIONAL FUNDS SEMIANNUAL REPORT

MONEY MARKET PORTFOLIOS

MAY 31, 2021 (UNAUDITED)

At May 31, 2021, the annual management fees and contractual expense limitations for the Portfolios were based on the following annual rates as set forth in the table below.


	CONTRACTUAL
	ANNUAL MANAGEMENT FEES			EXPENSE LIMITATIONS
Treasury		0.13	%		0.15	%
U.S. Government		0.23	%		0.25	%
U.S. Government Select		0.18	%		0.20	%

The contractual expense reimbursement arrangements described above are expected to continue until at least April 1, 2022. The contractual expense reimbursement arrangements will continue automatically for periods of one-year (each such one-year period, a “Renewal Year”). The arrangements may be terminated, as to any succeeding Renewal Year, by NTI or a Portfolio upon 60 days’ written notice prior to the end of the current Renewal Year. The Board may terminate the contractual arrangements at any time with respect to a Portfolio if it determines that it is in the best interest of the Portfolio and its shareholders.

In addition, during the six months ended May 31, 2021, NTI reimbursed certain additional expenses that may be excepted expenses.

NTI may reimburse additional expenses or waive all or a portion of the management fees of the Portfolios from time to time, including to avoid a negative yield. Any such additional expense reimbursement or waiver would be voluntary and could be implemented, increased or decreased or discontinued at any time. There is no guarantee that a Portfolio will be able to avoid a negative yield. During the six months ended May 31, 2021, NTI reimbursed additional expenses in order to avoid a negative yield for the Portfolios. Portfolio level expenses reimbursed by NTI were allocated among the share classes in proportion to the relative net assets of each class. The amounts reimbursed by NTI are shown as Less expenses voluntarily reimbursed by investment adviser in the Statements of Operations. The voluntary expense reimbursement receivables at May 31, 2021 were approximately $10,183,000, $3,706,000 and $6,735,000 for the Treasury, U.S. Government and U.S. Government Select Portfolios, respectively, and are included as part of Receivable from affiliates for expense reimbursements in the Statements of Assets and Liabilities. Any such reimbursement is paid monthly to the Portfolios by NTI.

As compensation for services rendered as transfer agent, including the assumption by Northern Trust of the expenses related thereto, Northern Trust receives a fee, accrued daily and payable monthly, at an annual rate of 0.015 percent of the average daily net assets for all share classes of each Portfolio.

NTI has entered into a sub-administration agreement with Northern Trust, pursuant to which Northern Trust performs certain administrative services for the Portfolios. NTI pays Northern Trust for its sub-administration services out of NTI’s management fees.

For compensation as custodian, Northern Trust receives an amount based on a pre-determined schedule of charges approved by the Board. The Portfolios have entered into an expense offset arrangement with the custodian whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Portfolios’ custodian expenses, unless such uninvested cash balances receive a separate type of return. Custodian credits, if any, are shown as Less custodian credits in the Portfolios’ Statements of Operations.

Northern Funds Distributors, LLC, the distributor for the Portfolios, received no compensation from the Portfolios under its distribution agreement. However, it received compensation from NTI for its services as distributor pursuant to a separate letter agreement between it and NTI.

Under the Service Plan for Premier Shares, the Trust has entered into a servicing agreement with Northern Trust under which Northern Trust has agreed to provide certain shareholder account, administrative and other service functions to the shareholders of the Premier Shares of the Treasury Portfolio. In exchange for these services, Northern Trust, as servicing agent, receives a fee, accrued daily and payable monthly, at an annual rate of 0.05 percent of the average daily net assets of the Premier Shares of the Treasury Portfolio.

Certain officers of the Trust are also officers of Northern Trust and NTI. All officers serve without compensation from the Portfolios. The Trust provided a deferred compensation plan for its Trustees who are not officers of Northern Trust or NTI. Prior to August 22, 2013, under the deferred compensation plan, Trustees may have elected to defer all or a portion of their compensation. Effective August 22, 2013, the Trustees may no longer defer their compensation. Any amounts deferred and invested under the plan shall remain invested pursuant to the terms of the plan. Each Trustee’s account shall be deemed to be invested in shares of the U.S. Government Portfolio of the Trust and/or the Global Tactical Asset Allocation Fund of Northern Funds and/or at the discretion of the Trust, another money market fund selected by the Trust that complies with the provisions of Rule 2a-7 under the 1940 Act or one or more short-term fixed income instruments selected by the Trust that are “eligible securities” as defined by that rule. The net investment income, gains and losses achieved by such deemed investment shall be credited to the Trustee’s account as provided in the plan.

5. RELATED PARTY TRANSACTIONS

The Portfolios are permitted to purchase and sell securities from or to certain affiliated funds or portfolios under specified conditions outlined in Rule 17a-7 Procedures adopted by the Board. The procedures have been designed to ensure that any purchase or sale of securities by a Portfolio 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 these procedures, each transaction is effected at the current market price as defined in the Rule 17a-7 Procedures. For the six months ended May 31, 2021, the Portfolios did not have any purchases and/or sales of securities from an affiliated entity.

Certain uninvested cash balances of the Portfolios may receive a return from Northern Trust based on a market return it receives less an administrative fee. These amounts, if any, are shown on the Portfolios’ Statements of Operations as Income from affiliates.

8. INDEMNIFICATIONS AND WARRANTIES

In the ordinary course of their business, the Portfolios may enter into contracts or agreements that contain indemnifications or warranties. Future events could occur that lead to the execution of these provisions against the Portfolios. The maximum exposure to the Portfolios under these provisions is unknown, as this would involve future claims that have not yet occurred. However, the Portfolios have not had prior claims or losses pursuant to these contracts and believe the risk of loss to be remote.

9. NEW ACCOUNTING PRONOUNCEMENTS

In March 2020, the FASB issued Accounting Standards Update (ASU) 2020-04, Reference Rate Reform (Topic 848) “Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU 2020-04”), which provides optional temporary financial reporting relief from the effect of certain types of contract modifications due to the planned discontinuation of the LIBOR and other interbank-offered based reference rates as of the end of 2021. The new guidance is effective for certain reference rate-related contract modifications that occur during the period March 12, 2020 through December 31, 2022, and the adoption of ASU 2020-04 is elective. Management does not believe this update has a material impact on the Portfolios’ financial statements and disclosures.

10. LIBOR TRANSITION

Certain of the Portfolios’ investments, payment obligations and financing terms may be based on floating rates, such as LIBOR, Euro Interbank Offered Rate and other similar types of reference rates (each, a “Reference Rate”). On July 27, 2017, the Chief Executive of the UK Financial Conduct Authority (“FCA”), which regulates LIBOR, announced that the FCA will no longer persuade nor compel banks to submit rates for the calculation of LIBOR and certain other Reference Rates after 2021. The FCA and ICE Benchmark Administrator have since announced that most LIBOR settings will no longer be published after December 31, 2021 and a majority of U.S. dollar LIBOR settings will cease publication after June 30, 2023. The U.S. Federal Reserve, based on the recommendations of the New York Federal Reserve’s Alternative Reference Rate Committee (comprised of major derivative market participants and their regulators), has begun publishing SOFR that is intended to replace U.S. dollar LIBOR. Proposals for alternative reference rates for other currencies have also been announced or have already begun publication. Uncertainty related to the liquidity impact of the change in rates, and how to appropriately adjust these rates at the time of transition, poses risks for the Portfolios. The effect of any changes to, or discontinuation of, LIBOR on the Portfolios will depend on, among other things, (1) existing fallback or termination provisions in individual contracts and (2) whether, how, and when industry participants develop and adopt new reference rates and fallbacks for both legacy and new instruments and contracts. The expected discontinuation of LIBOR could have a significant impact on the financial markets in general and may also present heightened risk to market participants, including public companies, investment advisers, investment companies, and broker-dealers. The risks associated with this discontinuation and transition will be exacerbated if the work necessary to effect an orderly transition to an alternative reference rate is not completed in a timely manner. Accordingly, it is difficult to predict the full impact of the transition away from LIBOR on the Portfolios until new reference rates and fallbacks for both legacy and new instruments and contracts are commercially accepted and market practices become settled.

reducing staff), and have produced general concern and uncertainty. The impact of the coronavirus pandemic, and other epidemics and pandemics that may arise in the future could adversely affect national and global economies, individual companies and the market in general in a manner and for a period of time that cannot be foreseen at the present time and may adversely affect the value, volatility and liquidity of dividend and interest paying securities. In the event of a pandemic or an outbreak, there can be no assurance that the Portfolios and their service providers will be able to maintain normal business operations for an extended period of time or will not lose the services of key personnel on a temporary or long-term basis due to illness or other reasons, and could otherwise disrupt the ability of the Portfolios’ service providers to perform essential services. Certain economic and market conditions arising out of a pandemic or outbreak could result in a Portfolio’s inability to achieve its investment objectives, cause the postponement of reconstitution or rebalance dates for benchmark indices, adversely affect the prices and liquidity of the securities and other instruments in which a Portfolio invests, negatively impact a Portfolio’s performance, and cause losses on your investment in a Portfolio. Management is monitoring the development of the pandemic, which was ongoing as of the date of the financial statements, and is evaluating its impact on the financial position and operating results of the Portfolios.

12. SUBSEQUENT EVENTS

Management has evaluated subsequent events for the Portfolios through the date the financial statements were issued, and has concluded that there are no recognized or non-recognized subsequent events relevant for financial statement disclosure.

FUND EXPENSES		MAY 31, 2021 (UNAUDITED)

As a shareholder of the Portfolios, 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 Portfolios and to compare these costs with the 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, December 1, 2020 through May 31, 2021.

ACTUAL EXPENSES

The first line of the tables below provides information about actual account values and actual expenses. You may use the information in this line, 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 first line under the heading entitled Expenses Paid 12/1/2020 - 5/31/2021 to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the tables below provides information about hypothetical account values and hypothetical expenses based on the Portfolios’ actual expense ratios and an assumed rate of return of 5 percent per year before expenses, which is not the Portfolios’ 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 Portfolios and other funds. To do so, compare this 5 percent hypothetical example with the 5 percent hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads), redemption fees, or exchange fees, but shareholders of other funds may incur such costs. 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.

APPROVAL OF MANAGEMENT AGREEMENT		MAY 31, 2021 (UNAUDITED)

The Board of Trustees (the “Board” or the “Trustees”) of Northern Institutional Funds (the “Trust”) oversees the management of the Trust, including review of the investment performance and expenses of the investment portfolios covered by this Report (the “Portfolios”), at regularly scheduled meetings. In addition, the Trustees determine annually whether to approve and continue the Trust’s management agreement (the “Management Agreement”) for the Portfolios with Northern Trust Investments, Inc. (“Northern”).

The Management Agreement was re-approved with respect to all of the Portfolios by the Board, including all of the Trustees who are not parties to the Management Agreement or “interested persons” (as defined in the Investment Company Act of 1940, as amended (the “1940 Act”)) of any party thereto (the “Independent Trustees”) voting separately, at the annual contract renewal meeting held on May 19-20, 2021 (the “Annual Contract Meeting”).⁽¹⁾

In advance of, and at the Annual Contract Meeting, the Trustees received, considered and discussed a variety of information relating to the Management Agreement and Northern and its affiliates. This information included written materials and verbal presentations at Board meetings held via videoconference and telephonically on February 10-11, 2021 and April 8, 2021 (the “February and April Board meetings”) and at the Annual Contract Meeting. At the Annual Contract Meeting, the Trustees considered these reports and presentations and discussed the information that had been provided. Throughout the process, the Trustees also asked questions of and requested additional information from management. In connection with their deliberations, the Independent Trustees met separately with and were advised by their independent legal counsel and received a memorandum from their independent legal counsel regarding their responsibilities under applicable law. They also met in executive sessions at the Annual Contract Meeting, and each of the other Board meetings, with their independent legal counsel without employees of Northern present.

In evaluating the Management Agreement, the Trustees discussed with counsel Northern’s reports, presentations and other information that had been provided to them at the February and April Board meetings and at the Annual Contract Meeting, as well as their interactions with Northern throughout the year and in past years at various meetings. The Trustees noted that the evaluation process with respect to Northern and the Management Agreement was an on-going one throughout the year.

The materials reviewed by the Board included, without limitation: (i) information on the investment performance of the Portfolios in comparison to other mutual funds and performance benchmarks; (ii) compliance reports; (iii) information about Northern’s and its affiliates’ risk management processes, stress testing, credit research, business continuity and cyber-security programs; (iv)fees charged to and expenses borne by the Portfolios; (v) Northern’s profitability and costs and compensation paid to affiliates of Northern; (vi) the qualifications of Northern and its affiliates to provide services to the Portfolios; (vii) information regarding purchases and redemptions of each Portfolio’s shares; (viii) policies adopted by Northern regarding brokerage, including soft dollars, trade allocations and other matters; and (ix) the nature of the Portfolios’ shareholders. The Trustees also considered the nature, quality and extent of non-advisory services provided to the Portfolios by Northern and its affiliates.

More specifically, the Trustees reviewed, among other things, information relating to: (i) the terms of the Management Agreement; (ii) the Portfolios’ investment performance over different time periods in comparison to the investment performance of mutual fund peer groups and categories selected by an independent third-party provider of mutual fund data; (iii) the contractual and net management fees and total expenses (after expense reimbursements and fee waivers) of the Portfolios in comparison to those borne by mutual fund peer expense groups and categories selected by the independent third-party provider of mutual fund data; (iv) the management fees charged to the Portfolios compared to the management fees charged by Northern to its other comparable institutional accounts; (v) Northern’s staffing for the Portfolios and the experience of the portfolio managers, credit research and other personnel; (vi) Northern’s financial resources and its ability to attract and retain portfolio management talent; (vii) Northern’s investments in technology to benefit the Portfolios; (viii) the fees paid by the Portfolios to Northern and its affiliates for services, and the expenses incurred by them in connection with the provision of those services; and (ix) the benefits received by Northern and its affiliates from their service relationships with the Portfolios. The Trustees were provided with a description of the methodology the third-party data provider used to determine the similarity of the Portfolios with the funds included in their respective peer expense groups and peer expense and performance universes. The Trustees also considered the Portfolios’ relationship to other mutual funds advised and offered by Northern and other factors (including conditions and trends prevailing generally in the economy, the securities markets, and the industry). In evaluating the Management Agreement for each of the Portfolios, the Trustees gave weight to various factors including those discussed below, but did not identify any single factor as controlling their decision, and each Trustee may have attributed different weight to different factors.

Trust. The Trustees understood that the Management Agreement encompassed both the advisory and administrative functions being rendered by Northern and its affiliates. They considered the quality of Northern’s communications with and services to shareholders, as well as the expenditures made by Northern and its affiliates to improve the quality and scope of their services to the Portfolios. The Trustees considered the strength of Northern’s and its affiliates’ risk management processes, including with respect to the Portfolios’ regular reporting on stress testing. The Trustees also reviewed the compliance and administrative services provided to the Portfolios by Northern and its affiliates, including its oversight of the Portfolios’ day-to-day operations and fund accounting. The Trustees also noted that on a regular basis they received and reviewed information from the Trust’s Chief Compliance Officer regarding the Portfolios’ compliance policies and procedures pursuant to Rule 38a-1 under the 1940 Act. They also considered the quality of Northern’s compliance oversight program with respect to all of the Portfolios’ service providers and the continued involvement of Northern’s internal audit group in reviewing operations that support the Portfolios, as well as Northern’s responses to any compliance or operational issue raised during the year. The Trustees also took into account that the scope of services provided by Northern, and the undertakings required of Northern in connection with those services, including maintaining and monitoring its own and the Portfolios’ compliance programs, had expanded over time as a result of regulatory, market and other developments. In this regard, the Trustees also noted Northern’s initiatives undertaken in the past few years with respect to the Portfolios and their shareholders, including to address additional regulatory and reporting requirements. The Trustees took into account that each of the U.S. Government, U.S. Government Select and Treasury Portfolios had maintained a stable net asset value.

The Trustees also considered the qualifications, background and responsibilities of Northern’s senior management and investment personnel. They also noted Northern’s recruitment and retention plans for attracting high quality investment professionals, as well as its portfolio management compensation structure, and the consistency of investment approach with respect to the Portfolios. The Trustees also considered Northern’s and its affiliates’ strong financial position and stability.

The Trustees concluded that Northern was able to commit, and had committed, substantial financial and other resources to the operations of the Portfolios and was able to continue to provide quality services to the Portfolios.

Performance

The Trustees considered the investment performance of each Portfolio, including whether it had operated within its respective investment objectives, as well as its compliance with its investment restrictions. The Trustees also took into account the low interest rate environment in which the Portfolios had been and were operating and any actions taken by Northern with respect to the

Portfolios to prevent negative yields this year and in past years. The Trustees received information on the Portfolios’ investment performance for one, two, three, four, five and ten years, as well as performance for the most recent quarter and year-to-date. They compared the investment performance of the Portfolios to the performance of other registered funds and to rankings issued by the third-party mutual fund data provider. The Portfolios were ranked by the data provider in quintiles, ranging from first to fifth, where first is the most desirable quintile position and fifth is the least desirable. The Trustees also reviewed the Portfolios’ performance relative to their performance benchmarks and the Portfolios’ three-year performance and net expenses as calculated by the third-party mutual fund data provider.

The Trustees noted the following regarding each Portfolio’s performance relative to its performance universe:

•

Performance of the Treasury Portfolio (Shares and Premier) was in the first quintile for the one- and three-year periods ended January 31, 2021; and the performance of the Treasury Portfolio (Shares) was in the first quintile for the five-year period ended January 31, 2021.

•

Performance of the U.S. Government Select Portfolio was in the first quintile for the one-year period and in the second quintile for the three- and five-year periods ended January 31, 2021.

•

Performance of the U.S. Government Portfolio was in the second quintile for the one-, three- and five-year periods ended January 31, 2021.

The Trustees also noted that the Treasury and U.S. Government Select Portfolios had performed in-line with or outperformed its respective benchmark, and that the U.S. Government Portfolio slightly underperformed its benchmark, for the same periods.

They also considered that the U.S. Government and U.S. Government Select Portfolios were in the least desirable less return, more expenses portion of the performance and expenses comparison. They took into account that the two Portfolios had performance in the first or second quintiles relative to their respective performance universe for the one- and three-year time periods.

The Trustees took into account senior management’s and portfolio manager’s discussion of the Portfolios’ performance and explanation for differences in investment parameters of certain Portfolios and their peers. They also considered the Portfolios’ investment performance relative to the investor base the Portfolios are intended to serve. The Trustees noted the potential impact on performance of the relative risk parameters of the different Portfolios. Specifically, they took into consideration Northern’s investment strategies. In addition, the Trustees reviewed the consistency of Northern’s investment approach for the Portfolios and processes to address performance issues, if any.

The Trustees concluded, based on the information received, that the Portfolios’ performance was satisfactory.

Fee Rates, Costs of Services and Profitability

The Trustees also evaluated the Portfolios’ contractual and net (after expense reimbursements) management fee rates; the Portfolios’ total operating expense ratios; Northern’s contractual commitments to continue expense reimbursements for at least one year with respect to the Portfolios; and whether a consistent methodology was in place for determining the fees and expenses of the Portfolios. They noted that beginning in 2019 and through the date of the Annual Contract Meeting, Northern had been voluntarily waiving two basis points of fees for the U.S. Government Select Portfolio and that Northern had voluntarily waived expenses for each of the Portfolios in the past year to avoid negative yield. In addition, the Trustees considered actions taken in past years to reduce Portfolio expenses, such as other voluntary expense reimbursements, service provider fee reductions, and reductions in the contractual expense limitations for the U.S. Government and Treasury Portfolios.

The Trustees reviewed information on the fee rates paid by the Portfolios under the Management Agreement and the Portfolios’ total operating expense ratios compared to similar information for mutual funds advised by unaffiliated investment management firms, as prepared by the third-party mutual fund data provider. The third-party report compared the expenses of each Portfolio against its respective peer expense group and expense universe as determined by the third-party data provider. In comparing the Portfolios’ contractual and net management fees to those of comparable funds, the Trustees noted that the Portfolios’ management fees include both advisory and administrative costs. Among other data, the Trustees considered that for all of the Portfolios, the total operating expense ratios after reimbursement of expenses were at or below their respective peer expense universe medians. The Trustees also noted the following:

•

The Treasury Portfolio’s net management fee for all classes was below its peer expense group and expense universe medians, and its total expense ratio, after reimbursement of expenses, was in the first quintile of its peer expense group with respect to the Shares class. The total expense ratio, after reimbursement of expenses, of the Premier Shares class was in the fifth quintile of its peer expense group.

•

The U.S. Government Portfolio’s net management fee was above its peer expense group and expense universe medians, and its total expense ratio, after reimbursement of expenses, was in the fifth quintile of its peer expense group.

•

The U.S. Government Select Portfolio’s net management fee was above its peer expense group median and even with its peer expense universe median, and its total expense ratio, after reimbursement of expenses, was in the fifth quintile of its peer expense group.

The Trustees took into account Northern’s discussion of the Portfolios’ expenses and that Northern had reimbursed expenses and/or waived fees for each of the Portfolios. They also reviewed information comparing the Portfolios’ fee rates to the fee rates charged by Northern to similarly managed, private institutional accounts. The Trustees considered the difference in, and level of complexity of, services provided by Northern with regard to the private institutional accounts, as well as regulatory, operational and compliance differences, board and committee support provided by Northern to the Portfolios and other differences. The Trustees considered the fee comparisons in light of the differences in management of these different kinds of accounts. These comparisons assisted the Trustees in evaluating the reasonableness of the management fees paid by the Portfolios.

In addition, the Trustees considered the amount of assets in the Portfolios; the information provided by Northern relating to the costs of the services provided by it and its affiliates; and the profits realized by them through their relationship on a Portfolio-by-Portfolio basis and on an overall Trust basis and both before and after distribution and certain non-distribution costs. The Trustees considered Northern’s assumptions and methodology for allocating costs to each Portfolio, recognizing that cost allocation methodologies are inherently subjective and not audited.

The Trustees also discussed information provided by the third-party provider of mutual fund data with respect to Northern’s profitability compared to other publicly-traded advisers. They considered that comparisons of advisory agreement profitability across fund families are difficult because of numerous factors, including the types of funds managed, business mix, cost allocation methodologies and other factors. The Trustees also considered Northern’s expense reimbursements during the year. They also took into account the nature of the Portfolios and the high quality of the services provided by Northern. The Trustees understood that Northern should be entitled to earn a reasonable level of profit in exchange for the level of services it provides to the Portfolios. The Trustees concluded that Northern’s profitability was not unreasonable based on the services and benefits provided and the costs assumed by Northern and its affiliates. They also noted that Northern appeared to have the resources necessary to fulfill its obligations under its management and other agreements with the Portfolios.

Economies of Scale

The Trustees considered the extent to which economies of scale would be realized as the Portfolios grow and whether fee levels reflected these economies of scale for the benefit of shareholders. The Trustees noted that the management fee of each Portfolio did not have breakpoints. They took into account management’s discussion of the Portfolios’ management fee structure and considered Northern’s view that the Portfolios were sharing in economies of scale through the level at which the Portfolios’ management fees are set and through Northern’s contractual expense reimbursements that limit the expenses for the Portfolios

to specific levels. They agreed that breakpoints were not necessary with respect to the Portfolios at this time based on the level of management fees and the contractual expense reimbursements. The Trustees also considered the voluntary fee waivers and expense reimbursements made by Northern to the Portfolios to prevent negative yields this year and in past years.

The Trustees determined, on the basis of the foregoing, that the Portfolios’ current management fee structures were reasonable.

Other Benefits to Northern

The Trustees also reviewed other benefits accruing to Northern and its affiliates as a result of their relationship with the Portfolios. Those benefits included fees received by the affiliates for transfer agency, custodial and sub-administrative functions, as well as shareholder servicing fees from the Premier Shares of the Treasury Portfolio. The Trustees also considered that many of the Portfolios’ shareholders had other client relationships with Northern’s affiliates. In addition, the Trustees considered that the scale of the Portfolios provided opportunities to Northern to obtain securities trading advantages for its other advisory clients and that Northern and its affiliates benefit from their ability to leverage resources over a larger asset base.

After deliberation, the Trustees concluded with respect to each of the Portfolios that the management fees paid by the Portfolios were reasonable in light of the services provided by Northern, its costs and the Portfolios’ asset levels, and other factors including those discussed above and that renewal of the Management Agreement should be approved.

1. ORGANIZATION

Northern Trust Investments, Inc. (“NTI”), an indirect subsidiary of Northern Trust Corporation, serves as the investment adviser for the Liquid Assets Portfolio (the “Portfolio”). The Northern Trust Company (“Northern Trust”), an affiliate of NTI, serves as transfer agent, custodian and sub-administrator to the Portfolio. Northern Funds Distributors, LLC, not an affiliate of NTI, is the Trust’s distributor.

The Portfolio operates as a “government money market fund” as defined under Rule 2a-7 of the 1940 Act.

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently followed by the Portfolio in the preparation of its financial statements. These policies are in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.

A) VALUATION OF SECURITIES The investments held by the Portfolio are valued at amortized cost, which generally approximates fair value. Under this method, investments purchased at a discount or premium are valued by accreting or amortizing the difference between the original purchase price and maturity value of the issue over the period to effective maturity. If NTI has determined that amortized cost does not approximate fair value, such securities are fair valued in accordance with policies and procedures established by, and subject to oversight of, the Trust’s Board of Trustees (the “Board”).

The use of fair valuation involves the risk that the values used by the Portfolio to price its investments may be higher or lower than the values used by other unaffiliated investment companies and investors to price the same investments.

B) CASH AND CASH EQUIVALENTS Cash and cash equivalents may include cash and cash held in an interest-bearing deposit account at Northern Trust.

C) REPURCHASE AGREEMENTS The Portfolio may enter into repurchase agreements under the terms of a master repurchase agreement by which the Portfolio purchases securities for cash from a seller and agrees to resell those securities to the same seller at a specific price within a specified time or with an indefinite life and liquidity feature, which allows the Portfolio to resell the securities quarterly. The interest rate on such repurchase agreements resets daily. During the term of a repurchase agreement, the fair value of the underlying collateral, including accrued interest, is required to equal or exceed the fair value of the repurchase agreement. The underlying collateral for tri-party repurchase agreements is held in accounts for Northern Trust or NTI (and is not reflected in the assets of the Portfolio) as agent of the Portfolio, at The Bank of New York Mellon, State Street Bank and Trust Company or JPMorgan Chase which, in turn, holds securities through the book-entry system at the Federal Reserve Bank of New York. The underlying collateral for other repurchase agreements is held in a customer-only account for Northern Trust, as custodian for the Portfolio, at the Federal Reserve Bank of Chicago. The Portfolio is subject to credit risk on repurchase agreements to the extent that the counterparty fails to perform under the agreement and the value of the collateral received falls below the agreed repurchase price. If the seller defaults and the value of the collateral declines or if bankruptcy proceedings are commenced with respect to the seller of the security, realization of collateral by the Portfolio may be delayed or limited. The Portfolio has entered into such repurchase agreements, as reflected in its accompanying Schedule of Investments, as of May 31, 2021.

Pursuant to exemptive relief granted by the U.S. Securities and Exchange Commission (“SEC”), the Portfolio and certain other money market portfolios advised by NTI and Northern Trust may enter into joint repurchase agreements with non-affiliated counterparties through a master repurchase agreement. NTI administers and manages these joint repurchase agreements in accordance with and as part of its duties under its management agreement with the Portfolio and does not collect any additional fees from the Portfolio for such services. The Portfolio has entered into such joint repurchase agreements, during the period. There were no outstanding joint repurchase agreements at May 31, 2021.

The Portfolio may enter into transactions subject to enforceable netting arrangements (“Netting Arrangements”) under a repurchase agreement. Generally, Netting Arrangements allow the Portfolio to offset any exposure to a specific counterparty with any collateral received from or delivered to that counterparty. In addition, Netting Arrangements provide the right for the non-defaulting party to liquidate the collateral and calculate the net exposure to the defaulting party or request additional collateral. Generally, the Portfolio manages its cash collateral and securities collateral on a counterparty basis. As of May 31, 2021, the Portfolio was not invested in any portfolio securities other than the repurchase agreements described below, with gross exposures on the Statement of Assets and Liabilities, that could be netted subject to Netting Arrangements.

D) INVESTMENT TRANSACTIONS AND INCOME Investment transactions are recorded as of the trade date. The Portfolio determines the gain or loss realized from investment transactions by using an identified cost basis method. Interest income, if any, is recognized on an accrual basis and includes amortization of premiums and accretion of discounts.

E) EXPENSES The Portfolio is charged for those expenses that are directly attributable to the Portfolio. Expenses incurred that do not specifically relate to an individual Portfolio generally are allocated among all the portfolios in the Trust in proportion to each portfolio’s relative net assets. Expenses are recognized on an accrual basis.

The timing and character of distributions determined in accordance with federal income tax regulations may differ from financial statement amounts determined in accordance with U.S. GAAP due to differences in the treatment and recognition of investment income and realized gains and losses. These differences are primarily related to the capital loss carryforwards. Inherent differences in the recognition of income and capital gains for federal income tax purposes, which are permanent, may result in periodic reclassifications in the Portfolio’s capital accounts. These reclassifications may relate to net operating losses and distribution reclassifications. These reclassifications have no impact on the net assets or the net asset value (“NAV”) per share of the Portfolio.

At November 30, 2020, the following reclassifications were recorded:


Amounts in thousands	UNDISTRIBUTED NET INVESTMENT INCOME (LOSS)			ACCUMULATED UNDISTRIBUTED NET REALIZED GAINS (LOSSES)
Liquid Assets		$–	*		$–*

* Amounts round to less than $1,000.

G) FEDERAL INCOME TAXES No provision for federal income taxes has been made since the Portfolio’s policy is to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), applicable to regulated investment companies and to distribute, each year, substantially all of its taxable income and tax-exempt income to its shareholders.

The Regulated Investment Company Modernization Act of 2010 (the “Act”) allows capital losses to be carried forward for an unlimited period and to retain their character as either short-term or long-term. The Portfolio’s ability to utilize capital loss carryforwards in the future may be limited under the Code and related regulations based on the results of future transactions.

There were no unused capital loss carryforwards in the Portfolio as of November 30, 2020.

As of November 30, 2020, the Portfolio had no uncertain tax positions that would require financial statement recognition or disclosure. The Portfolio’s federal tax returns remain subject to examination by the Internal Revenue Service for three years after they are filed. Any interest or penalties incurred, if any, on future unknown, uncertain tax positions taken by the Portfolio will be recorded as Interest expense and Other expenses, respectively, on the Statement of Operations.

3. BANK BORROWINGS

The Trust and the Northern Funds, a registered investment company also advised by NTI, jointly entered into a $250,000,000 senior unsecured revolving credit facility on November 16, 2020, which is administered by Citibank, N.A., for liquidity and other purposes (the “Credit Facility”). The interest rate charged under the Credit Facility is equal to the sum of (i) the Federal Funds Rate plus (ii) if the one month London Interbank Offered Rate (“LIBOR”) on the date of borrowing exceeded such Federal Funds Rate, the amount by which it so exceeded, plus (iii) 1.25 percent. In addition, there is an annual commitment fee of 0.15 percent on the unused portion of the credit line under the Credit Facility, payable quarterly in arrears, which is included in Other expenses on the Statement of Operations. The Credit Facility will expire on November 15, 2021, unless renewed.

The Portfolio did not have any borrowings or incur any interest expense for the six months ended May 31, 2021. There were no outstanding loan amounts at May 31, 2021.

4. MANAGEMENT AND OTHER AGREEMENTS

As compensation for advisory and administration services and the assumption of related expenses, NTI is entitled to a management fee, computed daily and payable monthly, at the annual rate of 0.10 percent of the Portfolio’s average daily net assets.

NTI has contractually agreed to reimburse a portion of the operating expenses of the Portfolio (other than certain excepted expenses, i.e., acquired fund fees and expenses, the compensation paid to each independent Trustee of the Trust, expenses of third-party consultants engaged by the Board, membership dues paid to the Investment Company Institute and Mutual Fund Directors Forum, expenses in connection with the negotiation and renewal of the revolving credit facility, extraordinary expenses and interest) as shown on the accompanying Statement of Operations, to the extent the total annual portfolio operating expenses of the Portfolio exceed 0.03 percent of the Portfolio’s average daily net assets. The total annual portfolio operating expenses after expense reimbursement for the Portfolio may be higher than the contractual limitation as a result of certain excepted expenses that are not reimbursed. The amount of the reimbursement is included in Less expenses reimbursed by investment adviser as a reduction to Total Expenses in the Statement of Operations. The contractual expense reimbursement receivable at May 31, 2021 is shown as Receivable from affiliates for expense reimbursements in the Statement of Assets and Liabilities. Any such reimbursement is paid monthly to the Portfolio by NTI.

The contractual expense reimbursement arrangement described above is expected to continue until at least April 1, 2022. The contractual expense reimbursement arrangement will continue automatically for periods of one-year (each such one-year period, a “Renewal Year”). The arrangement may be terminated, as to any succeeding Renewal Year, by NTI or the Portfolio upon 60 days’ written notice prior to the end of the current Renewal Year. The Board may terminate the contractual arrangement at any time with respect to the Portfolio if it determines that it is in the best interest of the Portfolio and its shareholders.

In addition during the six months ended May 31, 2021, NTI reimbursed certain additional expenses that may be excepted expenses.


NORTHERN INSTITUTIONAL FUNDS SEMIANNUAL REPORT		11		LIQUID ASSETS PORTFOLIO

LIQUID ASSETS PORTFOLIO

NOTES TO THE FINANCIAL STATEMENTS continued

NTI may reimburse additional expenses or waive all or a portion of the management fees of the Portfolio from time to time, including to avoid a negative yield. Any such additional expense reimbursement or waiver would be voluntary and could be implemented, increased or decreased or discontinued at any time. There is no guarantee that the Portfolio will be able to avoid a negative yield. Any such reimbursement is paid monthly to the Portfolio by NTI.

During the six months ended May 31, 2021, NTI voluntarily reimbursed additional expenses that were less than $1,000.

NTI has entered into a sub-administration agreement with Northern Trust, pursuant to which Northern Trust performs certain administrative services for the Portfolio. NTI pays Northern Trust for its sub-administration services out of NTI’s management fees.

For compensation as custodian, Northern Trust receives an amount based on a pre-determined schedule of charges approved by the Board. The Portfolio has entered into an expense offset arrangement with the custodian whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Portfolio’s custodian expenses, unless such uninvested cash balances receive a separate type of return. Custodian credits, if any, are shown as Less custodian credits in the Portfolio’s Statement of Operations.

Northern Funds Distributors, LLC, the placement agent for the Portfolio, received no compensation from the Portfolio under the placement agency agreement. However, it received compensation from NTI for its services as placement agent pursuant to a separate letter agreement between it and NTI.

Certain officers of the Trust are also officers of Northern Trust and NTI. All officers serve without compensation from the Portfolio. The Trust provided a deferred compensation plan for its Trustees who are not officers of Northern Trust or NTI. Prior to August 22, 2013, under the deferred compensation plan, Trustees may have elected to defer all or a portion of their compensation. Effective August 22, 2013, the Trustees may no longer defer their compensation. Any amounts deferred and invested under the plan shall remain invested pursuant to the terms of the plan. Each Trustee’s account shall be deemed to be invested in shares of the U.S. Government Portfolio of the Trust and/or the Global Tactical Asset Allocation Fund of Northern Funds and/or at the discretion of the Trust, another money market fund selected by the Trust that complies with the provisions of Rule 2a-7 under the 1940 Act or one or more short-term fixed-income instruments selected by the Trust that are “eligible securities” as defined by that rule. The net investment income, gains and losses achieved by such deemed investment shall be credited to the Trustee’s account as provided in the plan.

5. RELATED PARTY TRANSACTIONS

The Portfolio is permitted to purchase and sell securities from or to certain affiliated funds or portfolios under specified conditions outlined in Rule 17a-7 Procedures adopted by the Board. The procedures have been designed to ensure that any purchase or sale of securities by the Portfolio 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 these procedures, each transaction is effected at the current market price as defined in the Rule 17a-7 Procedures. For the six months ended May 31, 2021, the Portfolio did not have any purchases and/or sales of securities from an affiliated entity.

Certain uninvested cash balances of the Portfolio may receive a return from Northern Trust based on a market return it receives less an administrative fee. These amounts (if any) are shown on the Portfolio’s Statement of Operations as Income from affiliates.

8. INDEMNIFICATIONS AND WARRANTIES

In the ordinary course of its business, the Portfolio may enter into contracts or agreements that contain indemnifications or warranties. Future events could occur that lead to the execution of these provisions against the Portfolio. The maximum exposure to the Portfolio under these provisions is unknown, as this would involve future claims that have not yet occurred. However, the Portfolio has not had prior claims or losses pursuant to these contracts and believes the risk of loss to be remote.

9. NEW ACCOUNTING PRONOUNCEMENTS

10. LIBOR TRANSITION

Certain of the Portfolio’s investments, payment obligations and financing terms may be based on floating rates, such as LIBOR, Euro Interbank Offered Rate and other similar types of reference rates (each, a “Reference Rate”). On July 27, 2017, the Chief Executive of the UK Financial Conduct Authority (“FCA”), which regulates LIBOR, announced that the FCA will no longer persuade nor compel banks to submit rates for the calculation of LIBOR and certain other Reference Rates after 2021. The FCA and ICE Benchmark Administrator have since announced that most LIBOR settings will no longer be published after December 31, 2021 and a majority of U.S. dollar LIBOR settings will cease publication after June 30, 2023. The U.S. Federal Reserve, based on the recommendations of the New York Federal Reserve’s Alternative Reference Rate Committee (comprised of major derivative market participants and their regulators), has begun publishing SOFR that is intended to replace U.S. dollar LIBOR.

Proposals for alternative reference rates for other currencies have also been announced or have already begun publication. Uncertainty related to the liquidity impact of the change in rates, and how to appropriately adjust these rates at the time of transition, poses risks for the Portfolio. The effect of any changes to, or discontinuation of, LIBOR on the Portfolio will depend on, among other things, (1) existing fallback or termination provisions in individual contracts and (2) whether, how, and when industry participants develop and adopt new reference rates and fallbacks for both legacy and new instruments and contracts. The expected discontinuation of LIBOR could have a significant impact on the financial markets in general and may also present heightened risk to market participants, including public companies, investment advisers, investment companies, and broker-dealers. The risks associated with this discontinuation and transition will be exacerbated if the work necessary to effect an orderly transition to an alternative reference rate is not completed in a timely manner. Accordingly, it is difficult to predict the full impact of the transition away from LIBOR on the Portfolio until new reference rates and fallbacks for both legacy and new instruments and contracts are commercially accepted and market practices become settled.

11. CORONAVIRUS (COVID-19) PANDEMIC

An outbreak of respiratory disease caused by a novel coronavirus was first detected in December 2019 and has spread internationally. The outbreak and efforts to contain its spread have resulted in closing borders and quarantines, restricting international and domestic travel, enhanced health screenings, cancelations, disrupted supply chains and customer activity, responses by businesses (including changes to operations and reducing staff), and have produced general concern and uncertainty. The impact of the coronavirus pandemic, and other epidemics and pandemics that may arise in the future could adversely affect national and global economies, individual companies and the market in general in a manner and for a period of time that cannot be foreseen at the present time and may adversely affect the value, volatility and liquidity of dividend and interest paying securities. In the event of a pandemic or an outbreak, there can be no assurance that the Portfolio and its service providers will be able to maintain normal business operations for an extended period of time or will not lose the services of key personnel on a temporary or long-term basis due to illness or other reasons, and could otherwise disrupt the ability of the Portfolio’s service providers to perform essential services. Certain economic and market conditions arising out of a pandemic or outbreak could result in the Portfolio’s inability to achieve its investment objectives, cause the postponement of reconstitution or rebalance dates for benchmark indices, adversely affect the prices and liquidity of the securities and other instruments in which the Portfolio invests, negatively impact the Portfolio’s performance, and cause losses on your investment in the Portfolio. Management is monitoring the development of the pandemic, which was ongoing as of the date of the financial statements, and is evaluating its impact on the financial position and operating results of the Portfolio.

FUND EXPENSES

MAY 31, 2021 (UNAUDITED)

As a shareholder of the Portfolio, 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 Portfolio and to compare these costs with the 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, December 1, 2020 through May 31, 2021.

ACTUAL EXPENSES

The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, 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 first line under the heading entitled Expenses Paid 12/1/2020 - 5/31/2021 to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table below provides information about hypothetical account values and hypothetical expenses based on the Portfolio’s actual expense ratio and an assumed rate of return of 5 percent per year before expenses, which is not the Portfolio’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 Portfolio and other funds. To do so, compare this 5 percent hypothetical example with the 5 percent 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 and do not reflect any transaction costs, such as sales charges (loads), redemption fees, or exchange fees, but shareholders of other funds may incur such costs. 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.

LIQUID ASSETS


SHARES	EXPENSE RATIO		BEGINNING ACCOUNT VALUE 12/1/2020		ENDING ACCOUNT VALUE 5/31/2021		EXPENSES PAID* 12/1/2020- 5/31/2021

Hypothetical (5% return before expenses)		0.03%	$	1,000.00	$	1,024.78	$	0.15

Expenses are calculated using the Portfolio’s annualized expense ratios, which represent ongoing expenses as a percentage of net assets for the six months ended May 31, 2021. Expenses are equal to the Portfolio’s annualized expense ratio multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period).

APPROVAL OF MANAGEMENT AGREEMENT

The Board of Trustees (the “Board” or the “Trustees”) of Northern Institutional Funds (the “Trust”) oversees the management of the Trust, including review of the investment performance and expenses of the Liquid Assets Portfolio (the “Portfolio”), at regularly scheduled meetings. In addition, the Trustees determine annually whether to approve and continue the Trust’s management agreement (the “Management Agreement”) for the Portfolio with Northern Trust Investments, Inc. (“Northern”).

The Management Agreement was re-approved with respect the Portfolio by the Board, including all of the Trustees who are not parties to the Management Agreement or “interested persons” (as defined in the Investment Company Act of 1940, as amended (the “1940 Act”)) of any party thereto (the “Independent Trustees”) voting separately, at the annual contract renewal meeting held on May 19-20, 2021 (the “Annual Contract Meeting”).⁽¹⁾

The materials reviewed by the Board included, without limitation: (i) information on the investment performance of the Portfolio in comparison to other mutual funds and performance benchmarks; (ii) compliance reports; (iii) information about Northern’s and its affiliates’ risk management processes, stress testing, credit research, business continuity and cyber-security programs; (iv) fees charged to and expenses borne by the Portfolio; (v) Northern’s profitability and costs and compensation paid to affiliates of Northern; (vi) the qualifications of Northern and its affiliates to provide services to the Portfolio; (vii) information regarding purchases and redemptions of Portfolio shares; (viii) policies adopted by Northern regarding brokerage, including soft dollars, trade allocations and other matters; and (ix) the nature of the Portfolio’s shareholders. The Trustees also considered the nature, quality and extent of non-advisory services provided to the Portfolio by Northern and its affiliates.

More specifically, the Trustees reviewed, among other things, information relating to: (i) the terms of the Management Agreement; (ii) the Portfolio’s investment performance over different time periods in comparison to the investment performance of mutual fund peer groups and categories selected by an independent third-party provider of mutual fund data; (iii) the contractual and net management fees and total expenses (after expense reimbursements and fee waivers) of the Portfolio in comparison to those borne by mutual fund peer expense groups and categories selected by the independent third-party provider of mutual fund data; (iv) the management fees charged to the Portfolio compared to the management fees charged by Northern to its other comparable institutional accounts; (v) Northern’s staffing for the Portfolio and the experience of the portfolio managers, credit research and other personnel; (vi) Northern’s financial resources and its ability to attract and retain portfolio management talent; (vii) Northern’s investments in technology to benefit the Portfolio; (viii) the fees paid by the Portfolio to Northern and its affiliates for services, and the expenses incurred by them in connection with the provision of those services; and (ix) the benefits received by Northern and its affiliates from their service relationships with the Portfolio. The Trustees were provided with a description of the methodology the third-party data provider used to determine the similarity of the Portfolio with the funds included in its peer expense group and peer expense and performance universe. The Trustees also considered other factors (including conditions and trends prevailing generally in the economy, the securities markets, and the industry). In evaluating the Management Agreement for the Portfolio, the Trustees gave weight to various factors including those discussed below, but did not identify any single factor as controlling their decision, and each Trustee may have attributed different weight to different factors.

Nature, Extent and Quality of Services

The Trustees considered, as part of their review, the nature, extent and quality of the services provided by Northern. In this regard, they considered both the investment advisory services, and separately the administrative and other non-advisory services that are provided to the Portfolio by Northern and its affiliates. These services include acting as the Portfolio’s administrator and sub-administrator, custodian and transfer agent and providing other services necessary for the operation of the Portfolio and the Trust. The Trustees understood that the Management Agreement encompassed both the advisory and administrative functions being rendered by Northern and its affiliates. They considered the quality of Northern’s communications with and services to shareholders, as well as the expenditures made by Northern and


LIQUID ASSETS PORTFOLIO		16		NORTHERN INSTITUTIONAL FUNDS SEMIANNUAL REPORT

LIQUID ASSETS PORTFOLIO

MAY 31, 2021 (UNAUDITED)

its affiliates to improve the quality and scope of their services to the Portfolio. The Trustees considered the strength of Northern’s and its affiliates’ risk management processes, including with respect to the Portfolio’s regular reporting on stress testing. The Trustees also reviewed the compliance and administrative services provided to the Portfolio by Northern and its affiliates, including its oversight of the Portfolio’s day-to-day operations and fund accounting. The Trustees also noted that on a regular basis they received and reviewed information from the Trust’s Chief Compliance Officer regarding the Portfolio’s compliance policies and procedures pursuant to Rule 38a-1 under the 1940 Act. They also considered the quality of Northern’s compliance oversight program with respect to all of the Portfolio’s service providers and the continued involvement of Northern’s internal audit group in reviewing operations that support the Portfolio, as well as Northern’s responses to any compliance or operational issues raised during the year. The Trustees also took into account that the scope of services provided by Northern, and the undertakings required of Northern in connection with those services, including maintaining and monitoring its own and the Portfolio’s compliance programs, had expanded over time as a result of regulatory, market and other developments. In this regard, the Trustees also noted Northern’s initiatives undertaken in the past few years with respect to the Portfolio and its shareholders, including to address additional regulatory and reporting requirements. The Trustees took into account that the Portfolio had maintained a stable net asset value.

The Trustees also considered the qualifications, background and responsibilities of Northern’s senior management and investment personnel. They also noted Northern’s recruitment and retention plans for attracting high quality investment professionals, as well as its portfolio management compensation structure, and the consistency of investment approach with respect to the Portfolio. The Trustees also considered Northern’s and its affiliates’ strong financial position and stability.

The Trustees concluded that Northern was able to commit, and had committed, substantial financial and other resources to the operations of the Portfolio and was able to continue to provide quality services to the Portfolio.

Performance

The Trustees considered the investment performance of the Portfolio, including whether it had operated within its investment objective, as well as its compliance with its investment restrictions. The Trustees also took into account the low interest rate environment in which the Portfolio had been and was operating and any actions taken by Northern with respect to the Portfolio to prevent negative yields this year and in past years. The Trustees received information on the Portfolio’s investment performance for one, two, three, four, five and ten years, as well as performance for the most recent quarter and year-to-date. They compared the investment performance of the Portfolio to the performance of other Securities and Exchange Commission (“SEC”)-registered funds and to rankings issued by the third-party mutual fund data provider. The Portfolio was ranked by the data provider in quintiles, ranging from first to fifth, where first is the most desirable quintile position and fifth is the least desirable. The Trustees also reviewed the Portfolio’s performance relative to its performance benchmark and the Portfolio’s three-year performance versus net expenses as calculated by the third-party mutual fund data provider. The Trustees noted that the performance of the Portfolio was in the first quintile for the one-, three- and five-year periods ended January 31, 2021 and had outperformed its benchmark for the same periods.

The Trustees took into account senior management’s and portfolio manager’s discussion of the Portfolio’s performance and explanation for differences in investment parameters of the Portfolio and its peers. They also considered the Portfolio’s investment performance relative to the investor base the Portfolio is intended to serve. The Trustees noted the potential impact on performance of the relative risk parameters of the Portfolio. Specifically, they took into consideration Northern’s investment strategies. In addition, the Trustees reviewed the consistency of Northern’s investment approach for the Portfolio and processes to address performance issues, if any.

The Trustees concluded, based on the information received, that the Portfolio’s performance was satisfactory.

Fee Rates, Costs of Services and Profitability

The Trustees also evaluated the Portfolio’s contractual and net (after expense reimbursements) management fee rates; the Portfolio’s total operating expense ratio; Northern’s contractual commitments to continue expense reimbursements for at least one year with respect to the Portfolio; and whether a consistent methodology was in place for determining the fees and expenses of the Portfolio. In addition, the Trustees considered actions taken in past years to reduce the Portfolio’s expenses, such as service provider fee reductions.

The Trustees reviewed information on the fee rates paid by the Portfolio under the Management Agreement and the Portfolio’s total operating expense ratio compared to similar information for mutual funds advised by unaffiliated investment management firms, as prepared by the third-party mutual fund data provider. The third-party report compared the expenses of the Portfolio against its peer expense group and expense universe as determined by the third-party data provider. In comparing the Portfolio’s contractual and net management fees to those of comparable funds, the Trustees noted that the Portfolio’s management fee includes both advisory and administrative costs. Among other data, the Trustees considered that the Portfolio’s total operating expense ratio after reimbursement of expenses was below its peer expense universe median and was in the first quintile of its peer expense group.

APPROVAL OF MANAGEMENT AGREEMENT continued

MAY 31, 2021 (UNAUDITED)

The Trustees took into account Northern’s discussion of the Portfolio’s expenses and that Northern had reimbursed expenses and/or waived fees for the Portfolio. They also reviewed information comparing the Portfolio’s fee rate to the fee rates charged by Northern to similarly managed, private institutional accounts. The Trustees considered the difference in, and level of complexity of, services provided by Northern with regard to the private institutional accounts, as well as regulatory, operational and compliance differences, board and committee support provided by Northern to the Portfolio and other differences. The Trustees considered the fee comparisons in light of the differences in management of these different kinds of accounts. These comparisons assisted the Trustees in evaluating the reasonableness of the management fees paid by the Portfolio.

In addition, the Trustees considered the amount of assets in the Portfolio; the information provided by Northern relating to the costs of the services provided by it and its affiliates; and the profits realized by them through their relationship on a portfolio-by-portfolio basis and on an overall Trust basis and both before and after distribution and certain non-distribution costs. The Trustees considered Northern’s assumptions and methodology for allocating costs to the Portfolio, recognizing that cost allocation methodologies are inherently subjective and not audited.

The Trustees also discussed information provided by the third-party provider of mutual fund data with respect to Northern’s profitability compared to other publicly-traded advisers. They considered that comparisons of advisory agreement profitability across fund families are difficult because of numerous factors, including the types of funds managed, business mix, cost allocation methodologies and other factors. The Trustees also considered Northern’s expense reimbursements during the year. They also took into account the nature of the Portfolio and the high quality of the services provided by Northern. The Trustees understood that Northern should be entitled to earn a reasonable level of profit in exchange for the level of services it provides to the Portfolio. The Trustees concluded that Northern’s profitability was not unreasonable based on the services and benefits provided and the costs assumed by Northern and its affiliates. They also noted that Northern appeared to have the resources necessary to fulfill its obligations under its management and other agreements with the Portfolio.

Economies of Scale

The Trustees considered the extent to which economies of scale would be realized as the Portfolio grows and whether fee levels reflected these economies of scale for the benefit of shareholders. The Trustees noted that the management fee of the Portfolio did not have breakpoints. They took into account management’s discussion of the Portfolio’s management fee structure and considered Northern’s view that the Portfolio is sharing in economies of scale through the level at which the Portfolio’s management fees are set and through Northern’s contractual expense reimbursements that limit the expenses for the Portfolio to a specific level. They agreed that breakpoints were not necessary with respect to the Portfolio at this time based on the level of management fees and the contractual expense reimbursements.

The Trustees determined, on the basis of the foregoing, that the Portfolio’s current management fee structure was reasonable.

Other Benefits to Northern

The Trustees also reviewed other benefits accruing to Northern and its affiliates as a result of their relationship with the Portfolio. Those benefits included fees received by the affiliates for transfer agency, custodial and sub-administrative functions. The Trustees also considered that many of the Portfolio’s shareholders had other client relationships with Northern’s affiliates. In addition, the Trustees considered that the scale of the Portfolio provided opportunities to Northern to obtain securities trading advantages for its other advisory clients and that Northern and its affiliates benefit from their ability to leverage resources over a larger asset base.

After deliberation, the Trustees concluded with respect to the Portfolio that the management fee paid by the Portfolio was reasonable in light of the services provided by Northern, its costs and the Portfolio’s asset levels, and other factors including those discussed above and that renewal of the Management Agreement should be approved.
