The bond market after producing steady gains with low volatility for most of the 12 month period ended March 31 2020 experienced severe disruptions with the outbreak of the coronavirus in early 2020 A combination of supply interruptions and sharply curtailed demand from both consumers and businesses appeared to end the longest economic expansion in US history and set the stage for a domestic and global recession These events brought an immediate response from the US Federal Reserve which cut short-term interest rates from 15 to zero created a wide range of new lending facilities and announced an asset-purchase program that included Treasuries mortgage-backed securities corporate issues and municipal bonds In total the Federal Reserversquos actions dwarfed the remedy for the 2008 financial crisis in both their scope and size The US government also responded with fiscal support in the form of a $22 trillion stimulus package that was passed in late March Policymakers overseas also sought to prop up their economies with monetary and fiscal stimulus designed to offset the impact of the coronavirus

The unprecedented suddenness of the downshift from positive to negative growth was matched by equally historic dislocations in global financial markets Yields on US Treasuries plunged in response to the prospect of a global recession investorsrsquo ldquoflight to safetyrdquo and the Federal Reserversquos accommodative

policies Yields on government bonds hit all-time lows in March with the yield on the benchmark 10-year Treasury briefly falling below 04 and the 30-year reaching 07 ndash leaving the entire US yield curve beneath 1 for the first time in history These events were accompanied by an inversion of the yield curve meaning that yields for short-term issues were above those of longer-term securities Market conditions normalized somewhat in response to the Federal Reserversquos aggressive actions with yields moving off their lows and the yield curve returning to a more typical slope Nevertheless the benchmark 10-year yield closed the period at 070 on March 31 2020 well below its level of 241 on March 31 2019

Although US Treasuries delivered strong performance during the downturn credit-sensitive areas of the market experienced significant declines that pushed their returns for the full 12-month period into negative territory High-yield corporate bonds weakened due to uncertainty regarding the outlook for economic growth and corporate earnings as well as from the sharp declines in oil prices Investment-grade corporate issues were also adversely affected by these trends although to a lesser extent than high yield bonds In addition higher-grade corporate issues received a significant boost in late March from the Federal Reserversquos announcement that it would include this category of

bonds in its asset-purchase programs US government money market funds for their part represented a notable source of stability amid the unusual volatility across many other areas of the financial markets

While certain segments of the bond market have faced challenges in recent months we would note that the investment-grade Bloomberg Barclays US Aggregate Bond Index gained 315 during the first calendar quarter of 2020 and 893 for the full 12-month period ended March 31 2020 In contrast the SampP 500 Index ndash a key measure of performance for US equities ndash returned -1960 and -698 for these same periods respectively We believe that this helps to illustrate bondsrsquo continued value as a source of potential portfolio diversification particularly in challenging times

Most important please know that our thoughts are with each one of our readers ndash our clients colleagues business partners and everyone else within our community ndash as we strive to overcome this health crisis Thank you for the continued opportunity to manage your assets

The 12-month period ended March 31 2020 represented a tale of two markets As designed the Fundrsquos return of 901 for the fiscal year ended March 31 2020 was essentially in line with the benchmark Bloomberg Barclays US Aggregate Bond Index return of 893 Much of calendar year 2019 saw risk assets rally based on monetary easing significant demand for positively yielding assets and hopes for a resolution to the USChina trade war The US Federal Reserve (the ldquoFedrdquo) cut interest rates three times during 2019 citing a lack of inflation and slowing global growth while investor demand for yield supported fixed-income assets The marketrsquos positive tone then abruptly changed during the first quarter of 2020 as the spread of COVID-19 along with the Saudi ArabiaRussia oil price war badly hurt investor sentiment as much of the worldrsquos population was gradually placed into quarantine The projected global economic toll sent risk markets into a tailspin with equities falling more than 30 from their highs while the interest rate spreads of risk assets widened dramatically negatively affecting fixed-income liquidity The Fed was quick to act cutting short-term rates to near zero and announcing quantitative easing measures to support asset prices The Fedrsquos actions along with the US Congressrsquo $23 trillion fiscal stimulus package eased market stress and helped risk assets to rebound somewhat off their lows by the end of March 2020

Stable domestic growth paired with global demand for yield supported investment-grade and high-yield credit markets throughout 2019 and the first six weeks of 2020 The sudden crisis caused by the spread of COVID-19 and the significant drop in oil prices caused credit spreads to widen during the month of March 2020

Trading costs surrounding monthly rebalancing and cash flow management detracted from Fund performance The Fund remains positioned to replicate the risk and return characteristics of its stated benchmark

Credit quality ratings are based on the conservative average of Moodyrsquos SampP Global and Fitch ratings If ratings from all three rating agencies disagree the model assigns the middle rating to the security If two of the three agree the model assigns the rating from those two to the security If none of these three rating agencies has assigned a rating the Fund will assign a rating of not rated The ratings expressed in SampP Globalrsquos nomenclature range from AAA (extremely strong capacity to meet its financial commitment) to D (in default) Short-term ratings expressed in SampP Globalrsquos nomenclature range from A-1 (obligorrsquos capacity to meet its financial commitment on the obligation is strong) to D (in default) The ratings represent the rating agenciesrsquo opinions of the quality of the securities they rate Ratings are relative and subjective and are not absolute standards of quality

Various inputs are used in determining the value of the Fundrsquos 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 (eg quoted prices in active markets for similar securities securities valuations based on commonly quoted benchmark interest rates and yield curves maturities ratings andor securities indices) Level 3 - Significant unobservable inputs (eg 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 Fundrsquos investments by the above fair value hierarchy as of March 31 2020

Northern Funds (the ldquoTrustrdquo) is a Delaware statutory trust and is registered under the Investment Company Act of 1940 as amended (the ldquo1940 Actrdquo) as an open-end management investment company The Trust offers 43 funds as of March 31 2020 each with its own investment objective (eg long-term capital appreciation total return or income consistent with preservation of capital) The Bond Index and US Treasury Index Funds (each a ldquoFundrdquo and collectively the ldquoFundsrdquo) are separate diversified investment portfolios of the Trust Each of the Funds is presented herein

Northern Trust Investments Inc (ldquoNTIrdquo) a subsidiary of The Northern Trust Company (ldquoNorthern Trustrdquo) serves as the investment adviser and administrator for each of the Funds Northern Trust serves as the custodian transfer agent and sub-administrator for the Trust Northern Funds Distributors LLC not an affiliate of NTI is the Trustrsquos distributor

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

The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of their financial statements These policies are in conformity with accounting principles generally accepted in the United States of America (ldquoUS GAAPrdquo) The preparation of financial statements in conformity with US 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

The net asset value (ldquoNAVrdquo) of each Fund is determined daily as of the close of regular trading on the New York Stock Exchange (ldquoNYSErdquo) generally 300 PM Central Time on each day the NYSE is open for trading

A) VALUATION OF SECURITIES AND DERIVATIVE CONTRACTS

Securities are valued at their fair value Equity securities traded on United States (ldquoUSrdquo) securities exchanges or in the NASDAQ National Market System are principally valued at the regular trading session closing price (generally 300 PM Central Time) on the exchange or market in which such securities are principally traded If any such security is not traded on a valuation date it is valued at the most recent quoted bid price Over-the-counter securities not reported in the NASDAQ National Market System are also generally valued at the most recent quoted bid price Fixed income securities however may be valued on the basis of evaluated prices provided by the Fundsrsquo approved independent third-party pricing services when such prices are believed to

reflect the fair value of such securities or broker provided prices Such prices may be determined by taking into account other similar securitiesrsquo prices yields maturities call features ratings prepayment speeds credit risks cash flows institutional size trading in similar groups of securities and developments related to specific securities

The values of securities of foreign issuers are generally based upon market quotations which depending upon local convention or regulation may be the last sale price the last bid price or the mean between the last bid and asked price as of in each case the close of the appropriate exchange or other designated time Foreign fixed income securities however may like domestic fixed income securities be valued based on evaluated prices provided by independent pricing services when such prices are believed to reflect the fair value of such securities

Shares of open-end investment companies other than exchange-traded funds are valued at their NAV Short-term investments with a maturity of 60 days or less are valued at their amortized cost which NTI as authorized by the Trustrsquos Board of Trustees (the ldquoBoardrdquo) has determined approximates fair value

Any securities for which market quotations are not readily available or are believed to be incorrect are valued at fair value as determined in good faith by NTI under the supervision of the Board The Trust in its discretion may make adjustments to the prices of securities held by a Fund if an event occurs after the publication of fair values normally used by a Fund but before the time as of which the Fund calculates its NAV depending on the nature and significance of the event consistent with applicable regulatory guidance and US GAAP This may occur particularly with respect to certain foreign securities held by a Fund in which case the Trust may use adjustment factors obtained from an independent evaluation service that are intended to reflect more accurately the fair value of those securities as of the time the Fundrsquos NAV is calculated

The use of fair valuation involves the risk that the values used by the Funds 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) FUTURES CONTRACTS Certain Funds invest in long or short exchange-traded futures contracts for hedging purposes to increase total return (ie for speculative purposes) or to maintain liquidity to meet potential shareholder redemptions to invest cash balances or dividends or to minimize trading costs When used as a hedge a Fund may sell a futures contract in order to offset a decrease in the fair value of its portfolio securities that might otherwise result from a market decline A Fund may do so either to hedge the value of its portfolio securities as a whole or to protect against declines occurring prior to sales of securities in the value of the securities to be sold Conversely a Fund may purchase a futures contract as a hedge in anticipation of purchases of securities In addition a Fund may utilize futures contracts in

FIXED INCOME INDEX FUNDS 88 NORTHERN FUNDS ANNUAL REPORT

F I X E D I N C O M E I N D E X F U N D S

MARCH 31 2020

anticipation of changes in the composition of its portfolio holdings A Fund bears the market risk arising from changes in the value of these financial instruments At the time a Fund enters into a futures contract it is generally required to make a margin deposit with the custodian of a specified amount of liquid assets Futures are marked-to-market each day with the change in value reflected in the unrealized gains or losses Risk may arise as a result of the potential inability of the counterparties to meet the terms of their contracts Credit risk is mitigated to the extent that the exchange on which a particular futures contract is traded assumes the risk of a counterparty defaulting on its obligations under the contract The Statements of Operations include any realized gains or losses on closed futures contracts in Net realized gains (losses) on futures contracts and any unrealized gains or losses on open futures contracts in Net change in unrealized appreciation (depreciation) on futures contracts

C) WHEN-ISSUEDDELAYED DELIVERY SECURITIES Certain Funds purchase securities with delivery or payment to occur at a later date beyond the normal settlement period At the time a Fund enters into the commitment to purchase a security the transaction is recorded and the value of the commitment is reflected in the NAV The value of the commitment may vary with market fluctuations No interest accrues to the Fund until settlement takes place At the time a Fund enters into this type of transaction it is required to segregate collateral of cash or liquid assets having a fair value at least equal to the amount of the commitment The Funds identify securities as segregated with a value that meets or exceeds the value of the commitments When-issued securities at March 31 2020 if any are noted in each Fundrsquos Schedule of Investments and in aggregate as Payable for when-issued securities in each Fundrsquos Statement of Assets and Liabilities

On January 6 2014 the Bond Index Fund entered into Master Securities Forward Transaction Agreements (ldquoMSFTArdquo) with certain counterparties pursuant to which each party has agreed to pledge cash andor securities as collateral to secure the repayment of its obligations to the other party under the MSFTA At March 31 2020 the Bond Index Fund received collateral from a broker in the form of a US Treasury Note The value amounted to approximately $282000 which is not included in the Statements of Assets and Liabilities No collateral has been pledged by the Bond Index Fund as of March 31 2020

D) MORTGAGE DOLLAR ROLLS Certain Funds enter into mortgage ldquodollar rollsrdquo in which a Fund sells securities for delivery in the future (generally within 30 days) and simultaneously contracts with the same counterparty to repurchase other mortgage securities on a specified future date During the roll period a Fund loses the right to receive principal and interest paid on the securities sold However a Fund would benefit to the extent of any difference between the price received for the securities sold and the lower forward price for the future purchase

For financial reporting and tax purposes the Funds treat mortgage dollar rolls as two separate transactions one involving the purchase of a security and a separate transaction involving a sale

E) INVESTMENT TRANSACTIONS AND INCOME Investment transactions are recorded as of the trade date The Funds determine the gain or loss realized from investment transactions by using an identified cost basis method Interest income is recognized on an accrual basis and includes amortization of premiums and accretion of discounts using the effective yield method The interest rates reflected in the Schedules of Investments represent the stated coupon rate annualized yield on date of purchase for discount notes the current reset rate for floating rate securities the 7-day yield for money market funds or for interest-only or principal-only securities the current effective yield Cost of investments includes amortization of premiums and accretion of discounts if any Dividend income is recognized on the ex-dividend date The Fundsrsquo income may be subject to certain state and local taxes

F) EXPENSES Each Fund is charged for those expenses that are directly attributable to that Fund Expenses incurred which do not specifically relate to an individual Fund generally are allocated among all Funds in the Trust in proportion to each Fundrsquos relative net assets

G) DISTRIBUTIONS TO SHAREHOLDERS Distributions of dividends from net investment income if any are declared and paid as follows

DECLARATION PAYMENT FREQUENCY FREQUENCY

Bond Index Daily Monthly

US Treasury Index Daily 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

Income dividends and capital gains distributions are determined in accordance with federal income tax regulations Such amounts may differ from income and capital gains recorded in accordance with US GAAP Accordingly the Funds may periodically make reclassifications among certain of their capital accounts to reflect differences between financial reporting and federal income tax basis distributions The reclassifications are reported in order to reflect the tax treatment for certain permanent differences that exist between income tax regulations and US GAAP These reclassifications relate to paydowns These reclassifications have no impact on the net assets or the NAVs per share of the Funds

H) FEDERAL INCOME TAXES No provision for federal income taxes has been made since each Fundrsquos policy is to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986 as amended (the ldquoCoderdquo) applicable to regulated investment companies and to distribute each year substantially all of its taxable income and capital gains to its shareholders

The Regulated Investment Company Modernization Act of 2010 (the ldquoActrdquo) eliminated the eight-year limit on the use of capital loss carryforwards that arise in taxable years beginning after its enactment date of December 22 2010 The changes became effective for the Funds for the fiscal year ended March 31 2012 Consequently capital losses incurred by the Funds in taxable years beginning with the taxable year ended March 31 2012 can be carried forward for an unlimited period Additionally post-enactment capital loss carryforwards will retain their character as either short-term or long-term capital losses instead of as short-term capital losses as under prior law The Fundsrsquo 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

On March 30 2017 the FASB issued Accounting Standards Update (ldquoASUrdquo) 2017-08 ldquoPremium Amortization on Purchased Callable Debt Securitiesrdquo (the ldquoASUrdquo) which amends the amortization period for certain purchased callable debt securities held at premium shortening such period to the earliest call date The new guidance requires an entity to amortize the premium on a callable debt security within its scope to the earliest call date unless the guidance for considering estimated prepayments as described above is applied If the call option is not exercised at the earliest call date the yield is reset to the effective yield using the payment terms of the security If the security has more than one call date and the premium was amortized to a call price greater than the next call price any excess of the amortized cost basis over the amount repayable at the next call date will be amortized to that date If there are no other call dates any excess of the amortized cost basis over the par amount will be amortized to maturity Discounts on purchased callable debt securities will continue to be amortized to the securityrsquos maturity date The ASU is effective for public business entities for fiscal years and interim

periods within those fiscal years beginning after December 15 2018 For all other entities the ASU is effective for fiscal years beginning after December 15 2019 and interim periods within fiscal years beginning after December 15 2020 Earlier application is permitted for all entities including adoption in an interim period If an entity early adopts the ASU in an interim period any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period The Funds have adopted the ASU The adoption of the ASU did not have a material impact on the financial statements

Certain of the Fundsrsquo 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 ldquoReference Raterdquo) On July 27 2017 the Chief Executive of the UK Financial Conduct Authority (ldquoFCArdquo) 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 Such announcement indicates that the continuation of LIBOR and other Reference Rates on the current basis cannot and will not be guaranteed after 2021 The transition away from Reference Rates may lead to increased volatility and illiquidity in markets that are tied to such Reference Rates and reduced values of Reference Rate-related instruments This announcement and any additional regulatory or market changes that occur as a result of the transition away from Reference Rates may have an adverse impact on a Fundrsquos investments performance or financial condition

Each Fund has adopted and implemented a Liquidity Risk Management Program (the ldquoProgramrdquo) as required by rule 22e-4 under the Investment Company Act of 1940 The Program seeks to assess manage and review each Fundrsquos Liquidity Risk ldquoLiquidity Riskrdquo is defined as the risk that a Fund could not meet requests to redeem shares issued by the Fund without significant dilution of remaining investorsrsquo interest in the Fund

The Board has appointed Northern Trust Investments Inc (ldquoNTIrdquo) the investment adviser to the Funds as the program administrator for the Program NTI has delegated oversight of the Program to the Northern Trust Asset Management Credit amp Liquidity Risk Committee (the ldquoCommitteerdquo)

At a meeting held on November 13-14 2019 the Board received and reviewed the annual written report of the Committee on behalf of NTI (the ldquoReportrdquo) concerning the operation of the Program for the period from December 1 2018 to September 30 2019 (the ldquoReporting Periodrdquo) The Report addressed the operation of the Program and assessed its adequacy and effectiveness of implementation

The Report summarized the operation of the Program and the information and factors considered by the Committee in reviewing the adequacy and effectiveness of the Programrsquos implementation with respect to each Fund Such information and factors included among other things (i) the liquidity risk framework used to assess manage and periodically review each Fundrsquos liquidity risk and the results of this assessment (ii) the methodology and inputs used to classify the liquidity of each Fundrsquos portfolio investments and the Committeersquos assessment that each Fundrsquos strategy is appropriate for an open-end mutual fund (iii) that each Fund held primarily highly liquid assets (investments that the Fund anticipates can be converted to cash within 3 business days or less in current market conditions without significantly changing their market value) (iv) that none of the Funds required the establishment of a highly liquid investment minimum and the methodology for that determination (v) confirmation that none of the Funds had breached the 15 maximum illiquid security threshold (investments that cannot be sold or disposed of in seven days or less in current market conditions without the sale of the investment significantly changing the market value of the investment) and the procedures for monitoring compliance with the limit and (vi) historical information regarding redemptions and shareholder concentration in each Fund The Report also summarized the changes made to the Program over the course of the year

Based on the review the Report concluded that the Program was being effectively implemented and that the Program was reasonably designed to assess and manage each Fundrsquos liquidity risk

There can be no assurance that the Program will achieve its objectives under all circumstances in the future Please refer to your Fundrsquos prospectus for more information regarding the Fundrsquos exposure to liquidity risk and other risks to which it may be subject

As a shareholder of the Funds you incur two types of costs (1) transaction costs if any and (2) 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 the ongoing costs of investing in other mutual funds

The Example is based on an investment of $1000 invested at the beginning of the period and held for the entire period October 1 2019 through March 31 2020

AC T UA L E X P E N S E S

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 $1000 (for example an $8600 account value divided by $1000 = 86) then multiply the result by the number in the first line under the heading entitled Expenses Paid 1012019 - 3312020 to estimate the expenses you paid on your account during this period

H Y P OT H E T I C A L E X A M P L E F O R C O M PA R I S O N P U R P O S E S

The second line in the tables below provides information about hypothetical account values and hypothetical expenses based on the Fundsrsquo actual expense ratios and an assumed rate of return of 5 percent per year before expenses which is not the Fundsrsquo 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 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 or other costs such as advisory fees related to affiliated money market fund investments but shareholders of other funds may incur such costs If these fees were included your costs would have been higher The information also does not reflect reimbursements on advisory fees incurred in connection with the investment of uninvested cash in affiliated money market funds (See page 92) which may result in different expense ratios in the Financial Highlights 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

3 US Government Securities Risk There is a risk that the US government will not provide financial support to its agencies instrumentalities or sponsored enterprises if it is not obligated to do so by law Many US government securities purchased by the Fund are not backed by the full faith and credit of the United States It is possible that the issuers of such securities will not have the funds to meet their payment obligations in the future

4 Interest RateMaturity Risk Securities with longer maturities tend to be more sensitive to changes in interest rates causing them to be more volatile than securities with shorter maturities Securities with shorter maturities tend to provide lower returns and be less volatile than securities with longer maturities Changing interest rates may have unpredictable effects on the markets and the Fundrsquos investments A low or declining interest rate environment poses risks to the Fundrsquos performance including the risk that proceeds from prepaid or maturing instruments may have to be reinvested at a lower interest rate Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund

A M E S S AG E F R O M

BO B B ROW N E

C H I E F I N V E S T M E N T O F F I C E R

The bond market after producing steady gains with low volatility for most of the 12 month period ended March 31 2020 experienced severe disruptions with the outbreak of the coronavirus in early 2020 A combination of supply interruptions and sharply curtailed demand from both consumers and businesses appeared to end the longest economic expansion in US history and set the stage for a domestic and global recession These events brought an immediate response from the US Federal Reserve which cut short-term interest rates from 15 to zero created a wide range of new lending facilities and announced an asset-purchase program that included Treasuries mortgage-backed securities corporate issues and municipal bonds In total the Federal Reserversquos actions dwarfed the remedy for the 2008 financial crisis in both their scope and size The US government also responded with fiscal support in the form of a $22 trillion stimulus package that was passed in late March Policymakers overseas also sought to prop up their economies with monetary and fiscal stimulus designed to offset the impact of the coronavirus

The unprecedented suddenness of the downshift from positive to negative growth was matched by equally historic dislocations in global financial markets Yields on US Treasuries plunged in response to the prospect of a global recession investorsrsquo ldquoflight to safetyrdquo and the Federal Reserversquos accommodative

policies Yields on government bonds hit all-time lows in March with the yield on the benchmark 10-year Treasury briefly falling below 04 and the 30-year reaching 07 ndash leaving the entire US yield curve beneath 1 for the first time in history These events were accompanied by an inversion of the yield curve meaning that yields for short-term issues were above those of longer-term securities Market conditions normalized somewhat in response to the Federal Reserversquos aggressive actions with yields moving off their lows and the yield curve returning to a more typical slope Nevertheless the benchmark 10-year yield closed the period at 070 on March 31 2020 well below its level of 241 on March 31 2019

Although US Treasuries delivered strong performance during the downturn credit-sensitive areas of the market experienced significant declines that pushed their returns for the full 12-month period into negative territory High-yield corporate bonds weakened due to uncertainty regarding the outlook for economic growth and corporate earnings as well as from the sharp declines in oil prices Investment-grade corporate issues were also adversely affected by these trends although to a lesser extent than high yield bonds In addition higher-grade corporate issues received a significant boost in late March from the Federal Reserversquos announcement that it would include this category of

bonds in its asset-purchase programs US government money market funds for their part represented a notable source of stability amid the unusual volatility across many other areas of the financial markets

While certain segments of the bond market have faced challenges in recent months we would note that the investment-grade Bloomberg Barclays US Aggregate Bond Index gained 315 during the first calendar quarter of 2020 and 893 for the full 12-month period ended March 31 2020 In contrast the SampP 500 Index ndash a key measure of performance for US equities ndash returned -1960 and -698 for these same periods respectively We believe that this helps to illustrate bondsrsquo continued value as a source of potential portfolio diversification particularly in challenging times

Most important please know that our thoughts are with each one of our readers ndash our clients colleagues business partners and everyone else within our community ndash as we strive to overcome this health crisis Thank you for the continued opportunity to manage your assets

The 12-month period ended March 31 2020 represented a tale of two markets As designed the Fundrsquos return of 901 for the fiscal year ended March 31 2020 was essentially in line with the benchmark Bloomberg Barclays US Aggregate Bond Index return of 893 Much of calendar year 2019 saw risk assets rally based on monetary easing significant demand for positively yielding assets and hopes for a resolution to the USChina trade war The US Federal Reserve (the ldquoFedrdquo) cut interest rates three times during 2019 citing a lack of inflation and slowing global growth while investor demand for yield supported fixed-income assets The marketrsquos positive tone then abruptly changed during the first quarter of 2020 as the spread of COVID-19 along with the Saudi ArabiaRussia oil price war badly hurt investor sentiment as much of the worldrsquos population was gradually placed into quarantine The projected global economic toll sent risk markets into a tailspin with equities falling more than 30 from their highs while the interest rate spreads of risk assets widened dramatically negatively affecting fixed-income liquidity The Fed was quick to act cutting short-term rates to near zero and announcing quantitative easing measures to support asset prices The Fedrsquos actions along with the US Congressrsquo $23 trillion fiscal stimulus package eased market stress and helped risk assets to rebound somewhat off their lows by the end of March 2020

Stable domestic growth paired with global demand for yield supported investment-grade and high-yield credit markets throughout 2019 and the first six weeks of 2020 The sudden crisis caused by the spread of COVID-19 and the significant drop in oil prices caused credit spreads to widen during the month of March 2020

Trading costs surrounding monthly rebalancing and cash flow management detracted from Fund performance The Fund remains positioned to replicate the risk and return characteristics of its stated benchmark

Credit quality ratings are based on the conservative average of Moodyrsquos SampP Global and Fitch ratings If ratings from all three rating agencies disagree the model assigns the middle rating to the security If two of the three agree the model assigns the rating from those two to the security If none of these three rating agencies has assigned a rating the Fund will assign a rating of not rated The ratings expressed in SampP Globalrsquos nomenclature range from AAA (extremely strong capacity to meet its financial commitment) to D (in default) Short-term ratings expressed in SampP Globalrsquos nomenclature range from A-1 (obligorrsquos capacity to meet its financial commitment on the obligation is strong) to D (in default) The ratings represent the rating agenciesrsquo opinions of the quality of the securities they rate Ratings are relative and subjective and are not absolute standards of quality

Various inputs are used in determining the value of the Fundrsquos 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 (eg quoted prices in active markets for similar securities securities valuations based on commonly quoted benchmark interest rates and yield curves maturities ratings andor securities indices) Level 3 - Significant unobservable inputs (eg 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 Fundrsquos investments by the above fair value hierarchy as of March 31 2020

Northern Funds (the ldquoTrustrdquo) is a Delaware statutory trust and is registered under the Investment Company Act of 1940 as amended (the ldquo1940 Actrdquo) as an open-end management investment company The Trust offers 43 funds as of March 31 2020 each with its own investment objective (eg long-term capital appreciation total return or income consistent with preservation of capital) The Bond Index and US Treasury Index Funds (each a ldquoFundrdquo and collectively the ldquoFundsrdquo) are separate diversified investment portfolios of the Trust Each of the Funds is presented herein

Northern Trust Investments Inc (ldquoNTIrdquo) a subsidiary of The Northern Trust Company (ldquoNorthern Trustrdquo) serves as the investment adviser and administrator for each of the Funds Northern Trust serves as the custodian transfer agent and sub-administrator for the Trust Northern Funds Distributors LLC not an affiliate of NTI is the Trustrsquos distributor

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

The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of their financial statements These policies are in conformity with accounting principles generally accepted in the United States of America (ldquoUS GAAPrdquo) The preparation of financial statements in conformity with US 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

The net asset value (ldquoNAVrdquo) of each Fund is determined daily as of the close of regular trading on the New York Stock Exchange (ldquoNYSErdquo) generally 300 PM Central Time on each day the NYSE is open for trading

A) VALUATION OF SECURITIES AND DERIVATIVE CONTRACTS

Securities are valued at their fair value Equity securities traded on United States (ldquoUSrdquo) securities exchanges or in the NASDAQ National Market System are principally valued at the regular trading session closing price (generally 300 PM Central Time) on the exchange or market in which such securities are principally traded If any such security is not traded on a valuation date it is valued at the most recent quoted bid price Over-the-counter securities not reported in the NASDAQ National Market System are also generally valued at the most recent quoted bid price Fixed income securities however may be valued on the basis of evaluated prices provided by the Fundsrsquo approved independent third-party pricing services when such prices are believed to

reflect the fair value of such securities or broker provided prices Such prices may be determined by taking into account other similar securitiesrsquo prices yields maturities call features ratings prepayment speeds credit risks cash flows institutional size trading in similar groups of securities and developments related to specific securities

The values of securities of foreign issuers are generally based upon market quotations which depending upon local convention or regulation may be the last sale price the last bid price or the mean between the last bid and asked price as of in each case the close of the appropriate exchange or other designated time Foreign fixed income securities however may like domestic fixed income securities be valued based on evaluated prices provided by independent pricing services when such prices are believed to reflect the fair value of such securities

Shares of open-end investment companies other than exchange-traded funds are valued at their NAV Short-term investments with a maturity of 60 days or less are valued at their amortized cost which NTI as authorized by the Trustrsquos Board of Trustees (the ldquoBoardrdquo) has determined approximates fair value

Any securities for which market quotations are not readily available or are believed to be incorrect are valued at fair value as determined in good faith by NTI under the supervision of the Board The Trust in its discretion may make adjustments to the prices of securities held by a Fund if an event occurs after the publication of fair values normally used by a Fund but before the time as of which the Fund calculates its NAV depending on the nature and significance of the event consistent with applicable regulatory guidance and US GAAP This may occur particularly with respect to certain foreign securities held by a Fund in which case the Trust may use adjustment factors obtained from an independent evaluation service that are intended to reflect more accurately the fair value of those securities as of the time the Fundrsquos NAV is calculated

The use of fair valuation involves the risk that the values used by the Funds 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) FUTURES CONTRACTS Certain Funds invest in long or short exchange-traded futures contracts for hedging purposes to increase total return (ie for speculative purposes) or to maintain liquidity to meet potential shareholder redemptions to invest cash balances or dividends or to minimize trading costs When used as a hedge a Fund may sell a futures contract in order to offset a decrease in the fair value of its portfolio securities that might otherwise result from a market decline A Fund may do so either to hedge the value of its portfolio securities as a whole or to protect against declines occurring prior to sales of securities in the value of the securities to be sold Conversely a Fund may purchase a futures contract as a hedge in anticipation of purchases of securities In addition a Fund may utilize futures contracts in

FIXED INCOME INDEX FUNDS 88 NORTHERN FUNDS ANNUAL REPORT

F I X E D I N C O M E I N D E X F U N D S

MARCH 31 2020

anticipation of changes in the composition of its portfolio holdings A Fund bears the market risk arising from changes in the value of these financial instruments At the time a Fund enters into a futures contract it is generally required to make a margin deposit with the custodian of a specified amount of liquid assets Futures are marked-to-market each day with the change in value reflected in the unrealized gains or losses Risk may arise as a result of the potential inability of the counterparties to meet the terms of their contracts Credit risk is mitigated to the extent that the exchange on which a particular futures contract is traded assumes the risk of a counterparty defaulting on its obligations under the contract The Statements of Operations include any realized gains or losses on closed futures contracts in Net realized gains (losses) on futures contracts and any unrealized gains or losses on open futures contracts in Net change in unrealized appreciation (depreciation) on futures contracts

C) WHEN-ISSUEDDELAYED DELIVERY SECURITIES Certain Funds purchase securities with delivery or payment to occur at a later date beyond the normal settlement period At the time a Fund enters into the commitment to purchase a security the transaction is recorded and the value of the commitment is reflected in the NAV The value of the commitment may vary with market fluctuations No interest accrues to the Fund until settlement takes place At the time a Fund enters into this type of transaction it is required to segregate collateral of cash or liquid assets having a fair value at least equal to the amount of the commitment The Funds identify securities as segregated with a value that meets or exceeds the value of the commitments When-issued securities at March 31 2020 if any are noted in each Fundrsquos Schedule of Investments and in aggregate as Payable for when-issued securities in each Fundrsquos Statement of Assets and Liabilities

On January 6 2014 the Bond Index Fund entered into Master Securities Forward Transaction Agreements (ldquoMSFTArdquo) with certain counterparties pursuant to which each party has agreed to pledge cash andor securities as collateral to secure the repayment of its obligations to the other party under the MSFTA At March 31 2020 the Bond Index Fund received collateral from a broker in the form of a US Treasury Note The value amounted to approximately $282000 which is not included in the Statements of Assets and Liabilities No collateral has been pledged by the Bond Index Fund as of March 31 2020

D) MORTGAGE DOLLAR ROLLS Certain Funds enter into mortgage ldquodollar rollsrdquo in which a Fund sells securities for delivery in the future (generally within 30 days) and simultaneously contracts with the same counterparty to repurchase other mortgage securities on a specified future date During the roll period a Fund loses the right to receive principal and interest paid on the securities sold However a Fund would benefit to the extent of any difference between the price received for the securities sold and the lower forward price for the future purchase

For financial reporting and tax purposes the Funds treat mortgage dollar rolls as two separate transactions one involving the purchase of a security and a separate transaction involving a sale

E) INVESTMENT TRANSACTIONS AND INCOME Investment transactions are recorded as of the trade date The Funds determine the gain or loss realized from investment transactions by using an identified cost basis method Interest income is recognized on an accrual basis and includes amortization of premiums and accretion of discounts using the effective yield method The interest rates reflected in the Schedules of Investments represent the stated coupon rate annualized yield on date of purchase for discount notes the current reset rate for floating rate securities the 7-day yield for money market funds or for interest-only or principal-only securities the current effective yield Cost of investments includes amortization of premiums and accretion of discounts if any Dividend income is recognized on the ex-dividend date The Fundsrsquo income may be subject to certain state and local taxes

F) EXPENSES Each Fund is charged for those expenses that are directly attributable to that Fund Expenses incurred which do not specifically relate to an individual Fund generally are allocated among all Funds in the Trust in proportion to each Fundrsquos relative net assets

G) DISTRIBUTIONS TO SHAREHOLDERS Distributions of dividends from net investment income if any are declared and paid as follows

DECLARATION PAYMENT FREQUENCY FREQUENCY

Bond Index Daily Monthly

US Treasury Index Daily 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

Income dividends and capital gains distributions are determined in accordance with federal income tax regulations Such amounts may differ from income and capital gains recorded in accordance with US GAAP Accordingly the Funds may periodically make reclassifications among certain of their capital accounts to reflect differences between financial reporting and federal income tax basis distributions The reclassifications are reported in order to reflect the tax treatment for certain permanent differences that exist between income tax regulations and US GAAP These reclassifications relate to paydowns These reclassifications have no impact on the net assets or the NAVs per share of the Funds

H) FEDERAL INCOME TAXES No provision for federal income taxes has been made since each Fundrsquos policy is to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986 as amended (the ldquoCoderdquo) applicable to regulated investment companies and to distribute each year substantially all of its taxable income and capital gains to its shareholders

On March 30 2017 the FASB issued Accounting Standards Update (ldquoASUrdquo) 2017-08 ldquoPremium Amortization on Purchased Callable Debt Securitiesrdquo (the ldquoASUrdquo) which amends the amortization period for certain purchased callable debt securities held at premium shortening such period to the earliest call date The new guidance requires an entity to amortize the premium on a callable debt security within its scope to the earliest call date unless the guidance for considering estimated prepayments as described above is applied If the call option is not exercised at the earliest call date the yield is reset to the effective yield using the payment terms of the security If the security has more than one call date and the premium was amortized to a call price greater than the next call price any excess of the amortized cost basis over the amount repayable at the next call date will be amortized to that date If there are no other call dates any excess of the amortized cost basis over the par amount will be amortized to maturity Discounts on purchased callable debt securities will continue to be amortized to the securityrsquos maturity date The ASU is effective for public business entities for fiscal years and interim

periods within those fiscal years beginning after December 15 2018 For all other entities the ASU is effective for fiscal years beginning after December 15 2019 and interim periods within fiscal years beginning after December 15 2020 Earlier application is permitted for all entities including adoption in an interim period If an entity early adopts the ASU in an interim period any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period The Funds have adopted the ASU The adoption of the ASU did not have a material impact on the financial statements

Each Fund has adopted and implemented a Liquidity Risk Management Program (the ldquoProgramrdquo) as required by rule 22e-4 under the Investment Company Act of 1940 The Program seeks to assess manage and review each Fundrsquos Liquidity Risk ldquoLiquidity Riskrdquo is defined as the risk that a Fund could not meet requests to redeem shares issued by the Fund without significant dilution of remaining investorsrsquo interest in the Fund

The Board has appointed Northern Trust Investments Inc (ldquoNTIrdquo) the investment adviser to the Funds as the program administrator for the Program NTI has delegated oversight of the Program to the Northern Trust Asset Management Credit amp Liquidity Risk Committee (the ldquoCommitteerdquo)

At a meeting held on November 13-14 2019 the Board received and reviewed the annual written report of the Committee on behalf of NTI (the ldquoReportrdquo) concerning the operation of the Program for the period from December 1 2018 to September 30 2019 (the ldquoReporting Periodrdquo) The Report addressed the operation of the Program and assessed its adequacy and effectiveness of implementation

The Report summarized the operation of the Program and the information and factors considered by the Committee in reviewing the adequacy and effectiveness of the Programrsquos implementation with respect to each Fund Such information and factors included among other things (i) the liquidity risk framework used to assess manage and periodically review each Fundrsquos liquidity risk and the results of this assessment (ii) the methodology and inputs used to classify the liquidity of each Fundrsquos portfolio investments and the Committeersquos assessment that each Fundrsquos strategy is appropriate for an open-end mutual fund (iii) that each Fund held primarily highly liquid assets (investments that the Fund anticipates can be converted to cash within 3 business days or less in current market conditions without significantly changing their market value) (iv) that none of the Funds required the establishment of a highly liquid investment minimum and the methodology for that determination (v) confirmation that none of the Funds had breached the 15 maximum illiquid security threshold (investments that cannot be sold or disposed of in seven days or less in current market conditions without the sale of the investment significantly changing the market value of the investment) and the procedures for monitoring compliance with the limit and (vi) historical information regarding redemptions and shareholder concentration in each Fund The Report also summarized the changes made to the Program over the course of the year

Based on the review the Report concluded that the Program was being effectively implemented and that the Program was reasonably designed to assess and manage each Fundrsquos liquidity risk

There can be no assurance that the Program will achieve its objectives under all circumstances in the future Please refer to your Fundrsquos prospectus for more information regarding the Fundrsquos exposure to liquidity risk and other risks to which it may be subject

As a shareholder of the Funds you incur two types of costs (1) transaction costs if any and (2) 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 the ongoing costs of investing in other mutual funds

The Example is based on an investment of $1000 invested at the beginning of the period and held for the entire period October 1 2019 through March 31 2020

AC T UA L E X P E N S E S

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 $1000 (for example an $8600 account value divided by $1000 = 86) then multiply the result by the number in the first line under the heading entitled Expenses Paid 1012019 - 3312020 to estimate the expenses you paid on your account during this period

H Y P OT H E T I C A L E X A M P L E F O R C O M PA R I S O N P U R P O S E S

The second line in the tables below provides information about hypothetical account values and hypothetical expenses based on the Fundsrsquo actual expense ratios and an assumed rate of return of 5 percent per year before expenses which is not the Fundsrsquo 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 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 or other costs such as advisory fees related to affiliated money market fund investments but shareholders of other funds may incur such costs If these fees were included your costs would have been higher The information also does not reflect reimbursements on advisory fees incurred in connection with the investment of uninvested cash in affiliated money market funds (See page 92) which may result in different expense ratios in the Financial Highlights 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

1 Fixed Income Market Risk The market values of fixed-income securities owned by the Fund may decline at times sharply and unpredictably Fixed income securities may experience increased volatility illiquidity or other potentially adverse effects in response to changing market conditions inflation changes in interest rates or lack of liquidity in markets which may be caused by numerous factors including but not limited to local or regional events such as war acts of terrorism the spread of infectious illness or other public health issues recessions or other events or adverse investor sentiment

2 Tracking Risk The Fundrsquos performance may vary substantially from the performance of the benchmark index it tracks as a result of share purchases and redemptions transaction costs expenses and other factors

3 US Government Securities Risk There is a risk that the US government will not provide financial support to its agencies instrumentalities or sponsored enterprises if it is not obligated to do so by law Many US government securities purchased by the Fund are not backed by the full faith and credit of the United States It is possible that the issuers of such securities will not have the funds to meet their payment obligations in the future

4 Interest RateMaturity Risk Securities with longer maturities tend to be more sensitive to changes in interest rates causing them to be more volatile than securities with shorter maturities Securities with shorter maturities tend to provide lower returns and be less volatile than securities with longer maturities Changing interest rates may have unpredictable effects on the markets and the Fundrsquos investments A low or declining interest rate environment poses risks to the Fundrsquos performance including the risk that proceeds from prepaid or maturing instruments may have to be reinvested at a lower interest rate Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund

The 12-month period ended March 31 2020 represented a tale of two markets As designed the Fundrsquos return of 901 for the fiscal year ended March 31 2020 was essentially in line with the benchmark Bloomberg Barclays US Aggregate Bond Index return of 893 Much of calendar year 2019 saw risk assets rally based on monetary easing significant demand for positively yielding assets and hopes for a resolution to the USChina trade war The US Federal Reserve (the ldquoFedrdquo) cut interest rates three times during 2019 citing a lack of inflation and slowing global growth while investor demand for yield supported fixed-income assets The marketrsquos positive tone then abruptly changed during the first quarter of 2020 as the spread of COVID-19 along with the Saudi ArabiaRussia oil price war badly hurt investor sentiment as much of the worldrsquos population was gradually placed into quarantine The projected global economic toll sent risk markets into a tailspin with equities falling more than 30 from their highs while the interest rate spreads of risk assets widened dramatically negatively affecting fixed-income liquidity The Fed was quick to act cutting short-term rates to near zero and announcing quantitative easing measures to support asset prices The Fedrsquos actions along with the US Congressrsquo $23 trillion fiscal stimulus package eased market stress and helped risk assets to rebound somewhat off their lows by the end of March 2020

Stable domestic growth paired with global demand for yield supported investment-grade and high-yield credit markets throughout 2019 and the first six weeks of 2020 The sudden crisis caused by the spread of COVID-19 and the significant drop in oil prices caused credit spreads to widen during the month of March 2020

Trading costs surrounding monthly rebalancing and cash flow management detracted from Fund performance The Fund remains positioned to replicate the risk and return characteristics of its stated benchmark

Credit quality ratings are based on the conservative average of Moodyrsquos SampP Global and Fitch ratings If ratings from all three rating agencies disagree the model assigns the middle rating to the security If two of the three agree the model assigns the rating from those two to the security If none of these three rating agencies has assigned a rating the Fund will assign a rating of not rated The ratings expressed in SampP Globalrsquos nomenclature range from AAA (extremely strong capacity to meet its financial commitment) to D (in default) Short-term ratings expressed in SampP Globalrsquos nomenclature range from A-1 (obligorrsquos capacity to meet its financial commitment on the obligation is strong) to D (in default) The ratings represent the rating agenciesrsquo opinions of the quality of the securities they rate Ratings are relative and subjective and are not absolute standards of quality

Various inputs are used in determining the value of the Fundrsquos 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 (eg quoted prices in active markets for similar securities securities valuations based on commonly quoted benchmark interest rates and yield curves maturities ratings andor securities indices) Level 3 - Significant unobservable inputs (eg 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 Fundrsquos investments by the above fair value hierarchy as of March 31 2020

Northern Funds (the ldquoTrustrdquo) is a Delaware statutory trust and is registered under the Investment Company Act of 1940 as amended (the ldquo1940 Actrdquo) as an open-end management investment company The Trust offers 43 funds as of March 31 2020 each with its own investment objective (eg long-term capital appreciation total return or income consistent with preservation of capital) The Bond Index and US Treasury Index Funds (each a ldquoFundrdquo and collectively the ldquoFundsrdquo) are separate diversified investment portfolios of the Trust Each of the Funds is presented herein

Northern Trust Investments Inc (ldquoNTIrdquo) a subsidiary of The Northern Trust Company (ldquoNorthern Trustrdquo) serves as the investment adviser and administrator for each of the Funds Northern Trust serves as the custodian transfer agent and sub-administrator for the Trust Northern Funds Distributors LLC not an affiliate of NTI is the Trustrsquos distributor

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

The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of their financial statements These policies are in conformity with accounting principles generally accepted in the United States of America (ldquoUS GAAPrdquo) The preparation of financial statements in conformity with US 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

The net asset value (ldquoNAVrdquo) of each Fund is determined daily as of the close of regular trading on the New York Stock Exchange (ldquoNYSErdquo) generally 300 PM Central Time on each day the NYSE is open for trading

A) VALUATION OF SECURITIES AND DERIVATIVE CONTRACTS

Securities are valued at their fair value Equity securities traded on United States (ldquoUSrdquo) securities exchanges or in the NASDAQ National Market System are principally valued at the regular trading session closing price (generally 300 PM Central Time) on the exchange or market in which such securities are principally traded If any such security is not traded on a valuation date it is valued at the most recent quoted bid price Over-the-counter securities not reported in the NASDAQ National Market System are also generally valued at the most recent quoted bid price Fixed income securities however may be valued on the basis of evaluated prices provided by the Fundsrsquo approved independent third-party pricing services when such prices are believed to

reflect the fair value of such securities or broker provided prices Such prices may be determined by taking into account other similar securitiesrsquo prices yields maturities call features ratings prepayment speeds credit risks cash flows institutional size trading in similar groups of securities and developments related to specific securities

The values of securities of foreign issuers are generally based upon market quotations which depending upon local convention or regulation may be the last sale price the last bid price or the mean between the last bid and asked price as of in each case the close of the appropriate exchange or other designated time Foreign fixed income securities however may like domestic fixed income securities be valued based on evaluated prices provided by independent pricing services when such prices are believed to reflect the fair value of such securities

Shares of open-end investment companies other than exchange-traded funds are valued at their NAV Short-term investments with a maturity of 60 days or less are valued at their amortized cost which NTI as authorized by the Trustrsquos Board of Trustees (the ldquoBoardrdquo) has determined approximates fair value

Any securities for which market quotations are not readily available or are believed to be incorrect are valued at fair value as determined in good faith by NTI under the supervision of the Board The Trust in its discretion may make adjustments to the prices of securities held by a Fund if an event occurs after the publication of fair values normally used by a Fund but before the time as of which the Fund calculates its NAV depending on the nature and significance of the event consistent with applicable regulatory guidance and US GAAP This may occur particularly with respect to certain foreign securities held by a Fund in which case the Trust may use adjustment factors obtained from an independent evaluation service that are intended to reflect more accurately the fair value of those securities as of the time the Fundrsquos NAV is calculated

The use of fair valuation involves the risk that the values used by the Funds 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) FUTURES CONTRACTS Certain Funds invest in long or short exchange-traded futures contracts for hedging purposes to increase total return (ie for speculative purposes) or to maintain liquidity to meet potential shareholder redemptions to invest cash balances or dividends or to minimize trading costs When used as a hedge a Fund may sell a futures contract in order to offset a decrease in the fair value of its portfolio securities that might otherwise result from a market decline A Fund may do so either to hedge the value of its portfolio securities as a whole or to protect against declines occurring prior to sales of securities in the value of the securities to be sold Conversely a Fund may purchase a futures contract as a hedge in anticipation of purchases of securities In addition a Fund may utilize futures contracts in

FIXED INCOME INDEX FUNDS 88 NORTHERN FUNDS ANNUAL REPORT

F I X E D I N C O M E I N D E X F U N D S

MARCH 31 2020

anticipation of changes in the composition of its portfolio holdings A Fund bears the market risk arising from changes in the value of these financial instruments At the time a Fund enters into a futures contract it is generally required to make a margin deposit with the custodian of a specified amount of liquid assets Futures are marked-to-market each day with the change in value reflected in the unrealized gains or losses Risk may arise as a result of the potential inability of the counterparties to meet the terms of their contracts Credit risk is mitigated to the extent that the exchange on which a particular futures contract is traded assumes the risk of a counterparty defaulting on its obligations under the contract The Statements of Operations include any realized gains or losses on closed futures contracts in Net realized gains (losses) on futures contracts and any unrealized gains or losses on open futures contracts in Net change in unrealized appreciation (depreciation) on futures contracts

C) WHEN-ISSUEDDELAYED DELIVERY SECURITIES Certain Funds purchase securities with delivery or payment to occur at a later date beyond the normal settlement period At the time a Fund enters into the commitment to purchase a security the transaction is recorded and the value of the commitment is reflected in the NAV The value of the commitment may vary with market fluctuations No interest accrues to the Fund until settlement takes place At the time a Fund enters into this type of transaction it is required to segregate collateral of cash or liquid assets having a fair value at least equal to the amount of the commitment The Funds identify securities as segregated with a value that meets or exceeds the value of the commitments When-issued securities at March 31 2020 if any are noted in each Fundrsquos Schedule of Investments and in aggregate as Payable for when-issued securities in each Fundrsquos Statement of Assets and Liabilities

On January 6 2014 the Bond Index Fund entered into Master Securities Forward Transaction Agreements (ldquoMSFTArdquo) with certain counterparties pursuant to which each party has agreed to pledge cash andor securities as collateral to secure the repayment of its obligations to the other party under the MSFTA At March 31 2020 the Bond Index Fund received collateral from a broker in the form of a US Treasury Note The value amounted to approximately $282000 which is not included in the Statements of Assets and Liabilities No collateral has been pledged by the Bond Index Fund as of March 31 2020

D) MORTGAGE DOLLAR ROLLS Certain Funds enter into mortgage ldquodollar rollsrdquo in which a Fund sells securities for delivery in the future (generally within 30 days) and simultaneously contracts with the same counterparty to repurchase other mortgage securities on a specified future date During the roll period a Fund loses the right to receive principal and interest paid on the securities sold However a Fund would benefit to the extent of any difference between the price received for the securities sold and the lower forward price for the future purchase

For financial reporting and tax purposes the Funds treat mortgage dollar rolls as two separate transactions one involving the purchase of a security and a separate transaction involving a sale

E) INVESTMENT TRANSACTIONS AND INCOME Investment transactions are recorded as of the trade date The Funds determine the gain or loss realized from investment transactions by using an identified cost basis method Interest income is recognized on an accrual basis and includes amortization of premiums and accretion of discounts using the effective yield method The interest rates reflected in the Schedules of Investments represent the stated coupon rate annualized yield on date of purchase for discount notes the current reset rate for floating rate securities the 7-day yield for money market funds or for interest-only or principal-only securities the current effective yield Cost of investments includes amortization of premiums and accretion of discounts if any Dividend income is recognized on the ex-dividend date The Fundsrsquo income may be subject to certain state and local taxes

F) EXPENSES Each Fund is charged for those expenses that are directly attributable to that Fund Expenses incurred which do not specifically relate to an individual Fund generally are allocated among all Funds in the Trust in proportion to each Fundrsquos relative net assets

G) DISTRIBUTIONS TO SHAREHOLDERS Distributions of dividends from net investment income if any are declared and paid as follows

DECLARATION PAYMENT FREQUENCY FREQUENCY

Bond Index Daily Monthly

US Treasury Index Daily 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

Income dividends and capital gains distributions are determined in accordance with federal income tax regulations Such amounts may differ from income and capital gains recorded in accordance with US GAAP Accordingly the Funds may periodically make reclassifications among certain of their capital accounts to reflect differences between financial reporting and federal income tax basis distributions The reclassifications are reported in order to reflect the tax treatment for certain permanent differences that exist between income tax regulations and US GAAP These reclassifications relate to paydowns These reclassifications have no impact on the net assets or the NAVs per share of the Funds

H) FEDERAL INCOME TAXES No provision for federal income taxes has been made since each Fundrsquos policy is to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986 as amended (the ldquoCoderdquo) applicable to regulated investment companies and to distribute each year substantially all of its taxable income and capital gains to its shareholders

On March 30 2017 the FASB issued Accounting Standards Update (ldquoASUrdquo) 2017-08 ldquoPremium Amortization on Purchased Callable Debt Securitiesrdquo (the ldquoASUrdquo) which amends the amortization period for certain purchased callable debt securities held at premium shortening such period to the earliest call date The new guidance requires an entity to amortize the premium on a callable debt security within its scope to the earliest call date unless the guidance for considering estimated prepayments as described above is applied If the call option is not exercised at the earliest call date the yield is reset to the effective yield using the payment terms of the security If the security has more than one call date and the premium was amortized to a call price greater than the next call price any excess of the amortized cost basis over the amount repayable at the next call date will be amortized to that date If there are no other call dates any excess of the amortized cost basis over the par amount will be amortized to maturity Discounts on purchased callable debt securities will continue to be amortized to the securityrsquos maturity date The ASU is effective for public business entities for fiscal years and interim

periods within those fiscal years beginning after December 15 2018 For all other entities the ASU is effective for fiscal years beginning after December 15 2019 and interim periods within fiscal years beginning after December 15 2020 Earlier application is permitted for all entities including adoption in an interim period If an entity early adopts the ASU in an interim period any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period The Funds have adopted the ASU The adoption of the ASU did not have a material impact on the financial statements

Each Fund has adopted and implemented a Liquidity Risk Management Program (the ldquoProgramrdquo) as required by rule 22e-4 under the Investment Company Act of 1940 The Program seeks to assess manage and review each Fundrsquos Liquidity Risk ldquoLiquidity Riskrdquo is defined as the risk that a Fund could not meet requests to redeem shares issued by the Fund without significant dilution of remaining investorsrsquo interest in the Fund

The Board has appointed Northern Trust Investments Inc (ldquoNTIrdquo) the investment adviser to the Funds as the program administrator for the Program NTI has delegated oversight of the Program to the Northern Trust Asset Management Credit amp Liquidity Risk Committee (the ldquoCommitteerdquo)

At a meeting held on November 13-14 2019 the Board received and reviewed the annual written report of the Committee on behalf of NTI (the ldquoReportrdquo) concerning the operation of the Program for the period from December 1 2018 to September 30 2019 (the ldquoReporting Periodrdquo) The Report addressed the operation of the Program and assessed its adequacy and effectiveness of implementation

The Report summarized the operation of the Program and the information and factors considered by the Committee in reviewing the adequacy and effectiveness of the Programrsquos implementation with respect to each Fund Such information and factors included among other things (i) the liquidity risk framework used to assess manage and periodically review each Fundrsquos liquidity risk and the results of this assessment (ii) the methodology and inputs used to classify the liquidity of each Fundrsquos portfolio investments and the Committeersquos assessment that each Fundrsquos strategy is appropriate for an open-end mutual fund (iii) that each Fund held primarily highly liquid assets (investments that the Fund anticipates can be converted to cash within 3 business days or less in current market conditions without significantly changing their market value) (iv) that none of the Funds required the establishment of a highly liquid investment minimum and the methodology for that determination (v) confirmation that none of the Funds had breached the 15 maximum illiquid security threshold (investments that cannot be sold or disposed of in seven days or less in current market conditions without the sale of the investment significantly changing the market value of the investment) and the procedures for monitoring compliance with the limit and (vi) historical information regarding redemptions and shareholder concentration in each Fund The Report also summarized the changes made to the Program over the course of the year

Based on the review the Report concluded that the Program was being effectively implemented and that the Program was reasonably designed to assess and manage each Fundrsquos liquidity risk

There can be no assurance that the Program will achieve its objectives under all circumstances in the future Please refer to your Fundrsquos prospectus for more information regarding the Fundrsquos exposure to liquidity risk and other risks to which it may be subject

As a shareholder of the Funds you incur two types of costs (1) transaction costs if any and (2) 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 the ongoing costs of investing in other mutual funds

The Example is based on an investment of $1000 invested at the beginning of the period and held for the entire period October 1 2019 through March 31 2020

AC T UA L E X P E N S E S

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 $1000 (for example an $8600 account value divided by $1000 = 86) then multiply the result by the number in the first line under the heading entitled Expenses Paid 1012019 - 3312020 to estimate the expenses you paid on your account during this period

H Y P OT H E T I C A L E X A M P L E F O R C O M PA R I S O N P U R P O S E S

The second line in the tables below provides information about hypothetical account values and hypothetical expenses based on the Fundsrsquo actual expense ratios and an assumed rate of return of 5 percent per year before expenses which is not the Fundsrsquo 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 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 or other costs such as advisory fees related to affiliated money market fund investments but shareholders of other funds may incur such costs If these fees were included your costs would have been higher The information also does not reflect reimbursements on advisory fees incurred in connection with the investment of uninvested cash in affiliated money market funds (See page 92) which may result in different expense ratios in the Financial Highlights 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

1 Fixed Income Market Risk The market values of fixed-income securities owned by the Fund may decline at times sharply and unpredictably Fixed income securities may experience increased volatility illiquidity or other potentially adverse effects in response to changing market conditions inflation changes in interest rates or lack of liquidity in markets which may be caused by numerous factors including but not limited to local or regional events such as war acts of terrorism the spread of infectious illness or other public health issues recessions or other events or adverse investor sentiment

2 Tracking Risk The Fundrsquos performance may vary substantially from the performance of the benchmark index it tracks as a result of share purchases and redemptions transaction costs expenses and other factors

3 US Government Securities Risk There is a risk that the US government will not provide financial support to its agencies instrumentalities or sponsored enterprises if it is not obligated to do so by law Many US government securities purchased by the Fund are not backed by the full faith and credit of the United States It is possible that the issuers of such securities will not have the funds to meet their payment obligations in the future

4 Interest RateMaturity Risk Securities with longer maturities tend to be more sensitive to changes in interest rates causing them to be more volatile than securities with shorter maturities Securities with shorter maturities tend to provide lower returns and be less volatile than securities with longer maturities Changing interest rates may have unpredictable effects on the markets and the Fundrsquos investments A low or declining interest rate environment poses risks to the Fundrsquos performance including the risk that proceeds from prepaid or maturing instruments may have to be reinvested at a lower interest rate Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund

The 12-month period ended March 31 2020 represented a tale of two markets As designed the Fundrsquos return of 901 for the fiscal year ended March 31 2020 was essentially in line with the benchmark Bloomberg Barclays US Aggregate Bond Index return of 893 Much of calendar year 2019 saw risk assets rally based on monetary easing significant demand for positively yielding assets and hopes for a resolution to the USChina trade war The US Federal Reserve (the ldquoFedrdquo) cut interest rates three times during 2019 citing a lack of inflation and slowing global growth while investor demand for yield supported fixed-income assets The marketrsquos positive tone then abruptly changed during the first quarter of 2020 as the spread of COVID-19 along with the Saudi ArabiaRussia oil price war badly hurt investor sentiment as much of the worldrsquos population was gradually placed into quarantine The projected global economic toll sent risk markets into a tailspin with equities falling more than 30 from their highs while the interest rate spreads of risk assets widened dramatically negatively affecting fixed-income liquidity The Fed was quick to act cutting short-term rates to near zero and announcing quantitative easing measures to support asset prices The Fedrsquos actions along with the US Congressrsquo $23 trillion fiscal stimulus package eased market stress and helped risk assets to rebound somewhat off their lows by the end of March 2020

Stable domestic growth paired with global demand for yield supported investment-grade and high-yield credit markets throughout 2019 and the first six weeks of 2020 The sudden crisis caused by the spread of COVID-19 and the significant drop in oil prices caused credit spreads to widen during the month of March 2020

Trading costs surrounding monthly rebalancing and cash flow management detracted from Fund performance The Fund remains positioned to replicate the risk and return characteristics of its stated benchmark

Credit quality ratings are based on the conservative average of Moodyrsquos SampP Global and Fitch ratings If ratings from all three rating agencies disagree the model assigns the middle rating to the security If two of the three agree the model assigns the rating from those two to the security If none of these three rating agencies has assigned a rating the Fund will assign a rating of not rated The ratings expressed in SampP Globalrsquos nomenclature range from AAA (extremely strong capacity to meet its financial commitment) to D (in default) Short-term ratings expressed in SampP Globalrsquos nomenclature range from A-1 (obligorrsquos capacity to meet its financial commitment on the obligation is strong) to D (in default) The ratings represent the rating agenciesrsquo opinions of the quality of the securities they rate Ratings are relative and subjective and are not absolute standards of quality

Various inputs are used in determining the value of the Fundrsquos 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 (eg quoted prices in active markets for similar securities securities valuations based on commonly quoted benchmark interest rates and yield curves maturities ratings andor securities indices) Level 3 - Significant unobservable inputs (eg 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 Fundrsquos investments by the above fair value hierarchy as of March 31 2020

Northern Funds (the ldquoTrustrdquo) is a Delaware statutory trust and is registered under the Investment Company Act of 1940 as amended (the ldquo1940 Actrdquo) as an open-end management investment company The Trust offers 43 funds as of March 31 2020 each with its own investment objective (eg long-term capital appreciation total return or income consistent with preservation of capital) The Bond Index and US Treasury Index Funds (each a ldquoFundrdquo and collectively the ldquoFundsrdquo) are separate diversified investment portfolios of the Trust Each of the Funds is presented herein

Northern Trust Investments Inc (ldquoNTIrdquo) a subsidiary of The Northern Trust Company (ldquoNorthern Trustrdquo) serves as the investment adviser and administrator for each of the Funds Northern Trust serves as the custodian transfer agent and sub-administrator for the Trust Northern Funds Distributors LLC not an affiliate of NTI is the Trustrsquos distributor

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

The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of their financial statements These policies are in conformity with accounting principles generally accepted in the United States of America (ldquoUS GAAPrdquo) The preparation of financial statements in conformity with US 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

The net asset value (ldquoNAVrdquo) of each Fund is determined daily as of the close of regular trading on the New York Stock Exchange (ldquoNYSErdquo) generally 300 PM Central Time on each day the NYSE is open for trading

A) VALUATION OF SECURITIES AND DERIVATIVE CONTRACTS

Securities are valued at their fair value Equity securities traded on United States (ldquoUSrdquo) securities exchanges or in the NASDAQ National Market System are principally valued at the regular trading session closing price (generally 300 PM Central Time) on the exchange or market in which such securities are principally traded If any such security is not traded on a valuation date it is valued at the most recent quoted bid price Over-the-counter securities not reported in the NASDAQ National Market System are also generally valued at the most recent quoted bid price Fixed income securities however may be valued on the basis of evaluated prices provided by the Fundsrsquo approved independent third-party pricing services when such prices are believed to

reflect the fair value of such securities or broker provided prices Such prices may be determined by taking into account other similar securitiesrsquo prices yields maturities call features ratings prepayment speeds credit risks cash flows institutional size trading in similar groups of securities and developments related to specific securities

The values of securities of foreign issuers are generally based upon market quotations which depending upon local convention or regulation may be the last sale price the last bid price or the mean between the last bid and asked price as of in each case the close of the appropriate exchange or other designated time Foreign fixed income securities however may like domestic fixed income securities be valued based on evaluated prices provided by independent pricing services when such prices are believed to reflect the fair value of such securities

Shares of open-end investment companies other than exchange-traded funds are valued at their NAV Short-term investments with a maturity of 60 days or less are valued at their amortized cost which NTI as authorized by the Trustrsquos Board of Trustees (the ldquoBoardrdquo) has determined approximates fair value

Any securities for which market quotations are not readily available or are believed to be incorrect are valued at fair value as determined in good faith by NTI under the supervision of the Board The Trust in its discretion may make adjustments to the prices of securities held by a Fund if an event occurs after the publication of fair values normally used by a Fund but before the time as of which the Fund calculates its NAV depending on the nature and significance of the event consistent with applicable regulatory guidance and US GAAP This may occur particularly with respect to certain foreign securities held by a Fund in which case the Trust may use adjustment factors obtained from an independent evaluation service that are intended to reflect more accurately the fair value of those securities as of the time the Fundrsquos NAV is calculated

The use of fair valuation involves the risk that the values used by the Funds 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) FUTURES CONTRACTS Certain Funds invest in long or short exchange-traded futures contracts for hedging purposes to increase total return (ie for speculative purposes) or to maintain liquidity to meet potential shareholder redemptions to invest cash balances or dividends or to minimize trading costs When used as a hedge a Fund may sell a futures contract in order to offset a decrease in the fair value of its portfolio securities that might otherwise result from a market decline A Fund may do so either to hedge the value of its portfolio securities as a whole or to protect against declines occurring prior to sales of securities in the value of the securities to be sold Conversely a Fund may purchase a futures contract as a hedge in anticipation of purchases of securities In addition a Fund may utilize futures contracts in

FIXED INCOME INDEX FUNDS 88 NORTHERN FUNDS ANNUAL REPORT

F I X E D I N C O M E I N D E X F U N D S

MARCH 31 2020

anticipation of changes in the composition of its portfolio holdings A Fund bears the market risk arising from changes in the value of these financial instruments At the time a Fund enters into a futures contract it is generally required to make a margin deposit with the custodian of a specified amount of liquid assets Futures are marked-to-market each day with the change in value reflected in the unrealized gains or losses Risk may arise as a result of the potential inability of the counterparties to meet the terms of their contracts Credit risk is mitigated to the extent that the exchange on which a particular futures contract is traded assumes the risk of a counterparty defaulting on its obligations under the contract The Statements of Operations include any realized gains or losses on closed futures contracts in Net realized gains (losses) on futures contracts and any unrealized gains or losses on open futures contracts in Net change in unrealized appreciation (depreciation) on futures contracts

C) WHEN-ISSUEDDELAYED DELIVERY SECURITIES Certain Funds purchase securities with delivery or payment to occur at a later date beyond the normal settlement period At the time a Fund enters into the commitment to purchase a security the transaction is recorded and the value of the commitment is reflected in the NAV The value of the commitment may vary with market fluctuations No interest accrues to the Fund until settlement takes place At the time a Fund enters into this type of transaction it is required to segregate collateral of cash or liquid assets having a fair value at least equal to the amount of the commitment The Funds identify securities as segregated with a value that meets or exceeds the value of the commitments When-issued securities at March 31 2020 if any are noted in each Fundrsquos Schedule of Investments and in aggregate as Payable for when-issued securities in each Fundrsquos Statement of Assets and Liabilities

On January 6 2014 the Bond Index Fund entered into Master Securities Forward Transaction Agreements (ldquoMSFTArdquo) with certain counterparties pursuant to which each party has agreed to pledge cash andor securities as collateral to secure the repayment of its obligations to the other party under the MSFTA At March 31 2020 the Bond Index Fund received collateral from a broker in the form of a US Treasury Note The value amounted to approximately $282000 which is not included in the Statements of Assets and Liabilities No collateral has been pledged by the Bond Index Fund as of March 31 2020

D) MORTGAGE DOLLAR ROLLS Certain Funds enter into mortgage ldquodollar rollsrdquo in which a Fund sells securities for delivery in the future (generally within 30 days) and simultaneously contracts with the same counterparty to repurchase other mortgage securities on a specified future date During the roll period a Fund loses the right to receive principal and interest paid on the securities sold However a Fund would benefit to the extent of any difference between the price received for the securities sold and the lower forward price for the future purchase

For financial reporting and tax purposes the Funds treat mortgage dollar rolls as two separate transactions one involving the purchase of a security and a separate transaction involving a sale

E) INVESTMENT TRANSACTIONS AND INCOME Investment transactions are recorded as of the trade date The Funds determine the gain or loss realized from investment transactions by using an identified cost basis method Interest income is recognized on an accrual basis and includes amortization of premiums and accretion of discounts using the effective yield method The interest rates reflected in the Schedules of Investments represent the stated coupon rate annualized yield on date of purchase for discount notes the current reset rate for floating rate securities the 7-day yield for money market funds or for interest-only or principal-only securities the current effective yield Cost of investments includes amortization of premiums and accretion of discounts if any Dividend income is recognized on the ex-dividend date The Fundsrsquo income may be subject to certain state and local taxes

F) EXPENSES Each Fund is charged for those expenses that are directly attributable to that Fund Expenses incurred which do not specifically relate to an individual Fund generally are allocated among all Funds in the Trust in proportion to each Fundrsquos relative net assets

G) DISTRIBUTIONS TO SHAREHOLDERS Distributions of dividends from net investment income if any are declared and paid as follows

DECLARATION PAYMENT FREQUENCY FREQUENCY

Bond Index Daily Monthly

US Treasury Index Daily 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

Income dividends and capital gains distributions are determined in accordance with federal income tax regulations Such amounts may differ from income and capital gains recorded in accordance with US GAAP Accordingly the Funds may periodically make reclassifications among certain of their capital accounts to reflect differences between financial reporting and federal income tax basis distributions The reclassifications are reported in order to reflect the tax treatment for certain permanent differences that exist between income tax regulations and US GAAP These reclassifications relate to paydowns These reclassifications have no impact on the net assets or the NAVs per share of the Funds

H) FEDERAL INCOME TAXES No provision for federal income taxes has been made since each Fundrsquos policy is to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986 as amended (the ldquoCoderdquo) applicable to regulated investment companies and to distribute each year substantially all of its taxable income and capital gains to its shareholders

On March 30 2017 the FASB issued Accounting Standards Update (ldquoASUrdquo) 2017-08 ldquoPremium Amortization on Purchased Callable Debt Securitiesrdquo (the ldquoASUrdquo) which amends the amortization period for certain purchased callable debt securities held at premium shortening such period to the earliest call date The new guidance requires an entity to amortize the premium on a callable debt security within its scope to the earliest call date unless the guidance for considering estimated prepayments as described above is applied If the call option is not exercised at the earliest call date the yield is reset to the effective yield using the payment terms of the security If the security has more than one call date and the premium was amortized to a call price greater than the next call price any excess of the amortized cost basis over the amount repayable at the next call date will be amortized to that date If there are no other call dates any excess of the amortized cost basis over the par amount will be amortized to maturity Discounts on purchased callable debt securities will continue to be amortized to the securityrsquos maturity date The ASU is effective for public business entities for fiscal years and interim

periods within those fiscal years beginning after December 15 2018 For all other entities the ASU is effective for fiscal years beginning after December 15 2019 and interim periods within fiscal years beginning after December 15 2020 Earlier application is permitted for all entities including adoption in an interim period If an entity early adopts the ASU in an interim period any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period The Funds have adopted the ASU The adoption of the ASU did not have a material impact on the financial statements

Certain of the Fundsrsquo 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 ldquoReference Raterdquo) On July 27 2017 the Chief Executive of the UK Financial Conduct Authority (ldquoFCArdquo) 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 Such announcement indicates that the continuation of LIBOR and other Reference Rates on the current basis cannot and will not be guaranteed after 2021 The transition away from Reference Rates may lead to increased volatility and illiquidity in markets that are tied to such Reference Rates and reduced values of Reference Rate-related instruments This announcement and any additional regulatory or market changes that occur as a result of the transition away from Reference Rates may have an adverse impact on a Fundrsquos investments performance or financial condition

Each Fund has adopted and implemented a Liquidity Risk Management Program (the ldquoProgramrdquo) as required by rule 22e-4 under the Investment Company Act of 1940 The Program seeks to assess manage and review each Fundrsquos Liquidity Risk ldquoLiquidity Riskrdquo is defined as the risk that a Fund could not meet requests to redeem shares issued by the Fund without significant dilution of remaining investorsrsquo interest in the Fund

The Board has appointed Northern Trust Investments Inc (ldquoNTIrdquo) the investment adviser to the Funds as the program administrator for the Program NTI has delegated oversight of the Program to the Northern Trust Asset Management Credit amp Liquidity Risk Committee (the ldquoCommitteerdquo)

At a meeting held on November 13-14 2019 the Board received and reviewed the annual written report of the Committee on behalf of NTI (the ldquoReportrdquo) concerning the operation of the Program for the period from December 1 2018 to September 30 2019 (the ldquoReporting Periodrdquo) The Report addressed the operation of the Program and assessed its adequacy and effectiveness of implementation

The Report summarized the operation of the Program and the information and factors considered by the Committee in reviewing the adequacy and effectiveness of the Programrsquos implementation with respect to each Fund Such information and factors included among other things (i) the liquidity risk framework used to assess manage and periodically review each Fundrsquos liquidity risk and the results of this assessment (ii) the methodology and inputs used to classify the liquidity of each Fundrsquos portfolio investments and the Committeersquos assessment that each Fundrsquos strategy is appropriate for an open-end mutual fund (iii) that each Fund held primarily highly liquid assets (investments that the Fund anticipates can be converted to cash within 3 business days or less in current market conditions without significantly changing their market value) (iv) that none of the Funds required the establishment of a highly liquid investment minimum and the methodology for that determination (v) confirmation that none of the Funds had breached the 15 maximum illiquid security threshold (investments that cannot be sold or disposed of in seven days or less in current market conditions without the sale of the investment significantly changing the market value of the investment) and the procedures for monitoring compliance with the limit and (vi) historical information regarding redemptions and shareholder concentration in each Fund The Report also summarized the changes made to the Program over the course of the year

Based on the review the Report concluded that the Program was being effectively implemented and that the Program was reasonably designed to assess and manage each Fundrsquos liquidity risk

There can be no assurance that the Program will achieve its objectives under all circumstances in the future Please refer to your Fundrsquos prospectus for more information regarding the Fundrsquos exposure to liquidity risk and other risks to which it may be subject

As a shareholder of the Funds you incur two types of costs (1) transaction costs if any and (2) 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 the ongoing costs of investing in other mutual funds

The Example is based on an investment of $1000 invested at the beginning of the period and held for the entire period October 1 2019 through March 31 2020

AC T UA L E X P E N S E S

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 $1000 (for example an $8600 account value divided by $1000 = 86) then multiply the result by the number in the first line under the heading entitled Expenses Paid 1012019 - 3312020 to estimate the expenses you paid on your account during this period

H Y P OT H E T I C A L E X A M P L E F O R C O M PA R I S O N P U R P O S E S

The second line in the tables below provides information about hypothetical account values and hypothetical expenses based on the Fundsrsquo actual expense ratios and an assumed rate of return of 5 percent per year before expenses which is not the Fundsrsquo 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 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 or other costs such as advisory fees related to affiliated money market fund investments but shareholders of other funds may incur such costs If these fees were included your costs would have been higher The information also does not reflect reimbursements on advisory fees incurred in connection with the investment of uninvested cash in affiliated money market funds (See page 92) which may result in different expense ratios in the Financial Highlights 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

1 Fixed Income Market Risk The market values of fixed-income securities owned by the Fund may decline at times sharply and unpredictably Fixed income securities may experience increased volatility illiquidity or other potentially adverse effects in response to changing market conditions inflation changes in interest rates or lack of liquidity in markets which may be caused by numerous factors including but not limited to local or regional events such as war acts of terrorism the spread of infectious illness or other public health issues recessions or other events or adverse investor sentiment

2 Tracking Risk The Fundrsquos performance may vary substantially from the performance of the benchmark index it tracks as a result of share purchases and redemptions transaction costs expenses and other factors

3 US Government Securities Risk There is a risk that the US government will not provide financial support to its agencies instrumentalities or sponsored enterprises if it is not obligated to do so by law Many US government securities purchased by the Fund are not backed by the full faith and credit of the United States It is possible that the issuers of such securities will not have the funds to meet their payment obligations in the future

4 Interest RateMaturity Risk Securities with longer maturities tend to be more sensitive to changes in interest rates causing them to be more volatile than securities with shorter maturities Securities with shorter maturities tend to provide lower returns and be less volatile than securities with longer maturities Changing interest rates may have unpredictable effects on the markets and the Fundrsquos investments A low or declining interest rate environment poses risks to the Fundrsquos performance including the risk that proceeds from prepaid or maturing instruments may have to be reinvested at a lower interest rate Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund

The 12-month reporting period ended March 31 2020 represented a tale of two markets The Bloomberg Barclays US Treasury Index returned 1323 during the 12 months ended March 31 2020 As designed the Fund performed in line with the index with 1329 return over the reporting period Much of calendar year 2019 saw risk assets rally based on monetary easing significant demand for positively yielding assets and hopes for a resolution to the USChina trade war The US Federal Reserve (the ldquoFedrdquo) cut interest rates three times during 2019 citing a lack of inflation and slowing global growth while investor demand for yield supported fixed-income assets The marketrsquos positive tone then abruptly changed during the first quarter of 2020 as the spread of COVID-19 along with the Saudi ArabiaRussia oil price war badly hurt investor sentiment as much of the worldrsquos population was gradually placed into quarantine The projected global economic toll sent risk markets into a tailspin with equities falling more than 30 from their highs while the interest rate spreads of risk assets widened dramatically negatively affecting fixed-income liquidity The Fed was quick to act cutting short-term rates to near zero and announcing quantitative easing measures to support asset prices The Fedrsquos actions along with the US Congressrsquo $23 trillion fiscal stimulus package eased market stress and helped risk assets to rebound somewhat off their lows by the end of March 2020

US Treasury yields plunged during the 12-month period ended March 31 2020 and the Treasury yield curve steepened During the period two-year Treasury yields fell 201 basis points to 0248 five-year yields fell 185 basis points to 038 10-year yields fell 174 basis points to 067 and 30-year yields fell 149 basis points to 132

Credit quality ratings are based on the conservative average of Moodyrsquos SampP Global and Fitch ratings If ratings from all three rating agencies disagree the model assigns the middle rating to the security If two of the three agree the model assigns the rating from those two to the security If none of these three rating agencies has assigned a rating the Fund will assign a rating of not rated The ratings expressed in SampP Globalrsquos nomenclature range from AAA (extremely strong capacity to meet its financial commitment) to D (in default) Short-term ratings expressed in SampP Globalrsquos nomenclature range from A-1 (obligorrsquos capacity to meet its financial commitment on the obligation is strong) to D (in default) The ratings represent the rating agenciesrsquo opinions of the quality of the securities they rate Ratings are relative and subjective and are not absolute standards of quality

Various inputs are used in determining the value of the Fundrsquos 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 (eg quoted prices in active markets for similar securities securities valuations based on commonly quoted benchmark interest rates and yield curves maturities ratings andor securities indices) Level 3 - Significant unobservable inputs (eg 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 Fundrsquos investments by the above fair value hierarchy as of March 31 2020

Credit quality ratings are based on the conservative average of Moodyrsquos SampP Global and Fitch ratings If ratings from all three rating agencies disagree the model assigns the middle rating to the security If two of the three agree the model assigns the rating from those two to the security If none of these three rating agencies has assigned a rating the Fund will assign a rating of not rated The ratings expressed in SampP Globalrsquos nomenclature range from AAA (extremely strong capacity to meet its financial commitment) to D (in default) Short-term ratings expressed in SampP Globalrsquos nomenclature range from A-1 (obligorrsquos capacity to meet its financial commitment on the obligation is strong) to D (in default) The ratings represent the rating agenciesrsquo opinions of the quality of the securities they rate Ratings are relative and subjective and are not absolute standards of quality

Various inputs are used in determining the value of the Fundrsquos 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 (eg quoted prices in active markets for similar securities securities valuations based on commonly quoted benchmark interest rates and yield curves maturities ratings andor securities indices) Level 3 - Significant unobservable inputs (eg 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 Fundrsquos investments by the above fair value hierarchy as of March 31 2020

Northern Funds (the ldquoTrustrdquo) is a Delaware statutory trust and is registered under the Investment Company Act of 1940 as amended (the ldquo1940 Actrdquo) as an open-end management investment company The Trust offers 43 funds as of March 31 2020 each with its own investment objective (eg long-term capital appreciation total return or income consistent with preservation of capital) The Bond Index and US Treasury Index Funds (each a ldquoFundrdquo and collectively the ldquoFundsrdquo) are separate diversified investment portfolios of the Trust Each of the Funds is presented herein

Northern Trust Investments Inc (ldquoNTIrdquo) a subsidiary of The Northern Trust Company (ldquoNorthern Trustrdquo) serves as the investment adviser and administrator for each of the Funds Northern Trust serves as the custodian transfer agent and sub-administrator for the Trust Northern Funds Distributors LLC not an affiliate of NTI is the Trustrsquos distributor

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

The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of their financial statements These policies are in conformity with accounting principles generally accepted in the United States of America (ldquoUS GAAPrdquo) The preparation of financial statements in conformity with US 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

The net asset value (ldquoNAVrdquo) of each Fund is determined daily as of the close of regular trading on the New York Stock Exchange (ldquoNYSErdquo) generally 300 PM Central Time on each day the NYSE is open for trading

A) VALUATION OF SECURITIES AND DERIVATIVE CONTRACTS

Securities are valued at their fair value Equity securities traded on United States (ldquoUSrdquo) securities exchanges or in the NASDAQ National Market System are principally valued at the regular trading session closing price (generally 300 PM Central Time) on the exchange or market in which such securities are principally traded If any such security is not traded on a valuation date it is valued at the most recent quoted bid price Over-the-counter securities not reported in the NASDAQ National Market System are also generally valued at the most recent quoted bid price Fixed income securities however may be valued on the basis of evaluated prices provided by the Fundsrsquo approved independent third-party pricing services when such prices are believed to

reflect the fair value of such securities or broker provided prices Such prices may be determined by taking into account other similar securitiesrsquo prices yields maturities call features ratings prepayment speeds credit risks cash flows institutional size trading in similar groups of securities and developments related to specific securities

The values of securities of foreign issuers are generally based upon market quotations which depending upon local convention or regulation may be the last sale price the last bid price or the mean between the last bid and asked price as of in each case the close of the appropriate exchange or other designated time Foreign fixed income securities however may like domestic fixed income securities be valued based on evaluated prices provided by independent pricing services when such prices are believed to reflect the fair value of such securities

Shares of open-end investment companies other than exchange-traded funds are valued at their NAV Short-term investments with a maturity of 60 days or less are valued at their amortized cost which NTI as authorized by the Trustrsquos Board of Trustees (the ldquoBoardrdquo) has determined approximates fair value

Any securities for which market quotations are not readily available or are believed to be incorrect are valued at fair value as determined in good faith by NTI under the supervision of the Board The Trust in its discretion may make adjustments to the prices of securities held by a Fund if an event occurs after the publication of fair values normally used by a Fund but before the time as of which the Fund calculates its NAV depending on the nature and significance of the event consistent with applicable regulatory guidance and US GAAP This may occur particularly with respect to certain foreign securities held by a Fund in which case the Trust may use adjustment factors obtained from an independent evaluation service that are intended to reflect more accurately the fair value of those securities as of the time the Fundrsquos NAV is calculated

The use of fair valuation involves the risk that the values used by the Funds 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) FUTURES CONTRACTS Certain Funds invest in long or short exchange-traded futures contracts for hedging purposes to increase total return (ie for speculative purposes) or to maintain liquidity to meet potential shareholder redemptions to invest cash balances or dividends or to minimize trading costs When used as a hedge a Fund may sell a futures contract in order to offset a decrease in the fair value of its portfolio securities that might otherwise result from a market decline A Fund may do so either to hedge the value of its portfolio securities as a whole or to protect against declines occurring prior to sales of securities in the value of the securities to be sold Conversely a Fund may purchase a futures contract as a hedge in anticipation of purchases of securities In addition a Fund may utilize futures contracts in

FIXED INCOME INDEX FUNDS 88 NORTHERN FUNDS ANNUAL REPORT

F I X E D I N C O M E I N D E X F U N D S

MARCH 31 2020

anticipation of changes in the composition of its portfolio holdings A Fund bears the market risk arising from changes in the value of these financial instruments At the time a Fund enters into a futures contract it is generally required to make a margin deposit with the custodian of a specified amount of liquid assets Futures are marked-to-market each day with the change in value reflected in the unrealized gains or losses Risk may arise as a result of the potential inability of the counterparties to meet the terms of their contracts Credit risk is mitigated to the extent that the exchange on which a particular futures contract is traded assumes the risk of a counterparty defaulting on its obligations under the contract The Statements of Operations include any realized gains or losses on closed futures contracts in Net realized gains (losses) on futures contracts and any unrealized gains or losses on open futures contracts in Net change in unrealized appreciation (depreciation) on futures contracts

C) WHEN-ISSUEDDELAYED DELIVERY SECURITIES Certain Funds purchase securities with delivery or payment to occur at a later date beyond the normal settlement period At the time a Fund enters into the commitment to purchase a security the transaction is recorded and the value of the commitment is reflected in the NAV The value of the commitment may vary with market fluctuations No interest accrues to the Fund until settlement takes place At the time a Fund enters into this type of transaction it is required to segregate collateral of cash or liquid assets having a fair value at least equal to the amount of the commitment The Funds identify securities as segregated with a value that meets or exceeds the value of the commitments When-issued securities at March 31 2020 if any are noted in each Fundrsquos Schedule of Investments and in aggregate as Payable for when-issued securities in each Fundrsquos Statement of Assets and Liabilities

On January 6 2014 the Bond Index Fund entered into Master Securities Forward Transaction Agreements (ldquoMSFTArdquo) with certain counterparties pursuant to which each party has agreed to pledge cash andor securities as collateral to secure the repayment of its obligations to the other party under the MSFTA At March 31 2020 the Bond Index Fund received collateral from a broker in the form of a US Treasury Note The value amounted to approximately $282000 which is not included in the Statements of Assets and Liabilities No collateral has been pledged by the Bond Index Fund as of March 31 2020

D) MORTGAGE DOLLAR ROLLS Certain Funds enter into mortgage ldquodollar rollsrdquo in which a Fund sells securities for delivery in the future (generally within 30 days) and simultaneously contracts with the same counterparty to repurchase other mortgage securities on a specified future date During the roll period a Fund loses the right to receive principal and interest paid on the securities sold However a Fund would benefit to the extent of any difference between the price received for the securities sold and the lower forward price for the future purchase

For financial reporting and tax purposes the Funds treat mortgage dollar rolls as two separate transactions one involving the purchase of a security and a separate transaction involving a sale

E) INVESTMENT TRANSACTIONS AND INCOME Investment transactions are recorded as of the trade date The Funds determine the gain or loss realized from investment transactions by using an identified cost basis method Interest income is recognized on an accrual basis and includes amortization of premiums and accretion of discounts using the effective yield method The interest rates reflected in the Schedules of Investments represent the stated coupon rate annualized yield on date of purchase for discount notes the current reset rate for floating rate securities the 7-day yield for money market funds or for interest-only or principal-only securities the current effective yield Cost of investments includes amortization of premiums and accretion of discounts if any Dividend income is recognized on the ex-dividend date The Fundsrsquo income may be subject to certain state and local taxes

F) EXPENSES Each Fund is charged for those expenses that are directly attributable to that Fund Expenses incurred which do not specifically relate to an individual Fund generally are allocated among all Funds in the Trust in proportion to each Fundrsquos relative net assets

G) DISTRIBUTIONS TO SHAREHOLDERS Distributions of dividends from net investment income if any are declared and paid as follows

DECLARATION PAYMENT FREQUENCY FREQUENCY

Bond Index Daily Monthly

US Treasury Index Daily 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

Income dividends and capital gains distributions are determined in accordance with federal income tax regulations Such amounts may differ from income and capital gains recorded in accordance with US GAAP Accordingly the Funds may periodically make reclassifications among certain of their capital accounts to reflect differences between financial reporting and federal income tax basis distributions The reclassifications are reported in order to reflect the tax treatment for certain permanent differences that exist between income tax regulations and US GAAP These reclassifications relate to paydowns These reclassifications have no impact on the net assets or the NAVs per share of the Funds

On March 30 2017 the FASB issued Accounting Standards Update (ldquoASUrdquo) 2017-08 ldquoPremium Amortization on Purchased Callable Debt Securitiesrdquo (the ldquoASUrdquo) which amends the amortization period for certain purchased callable debt securities held at premium shortening such period to the earliest call date The new guidance requires an entity to amortize the premium on a callable debt security within its scope to the earliest call date unless the guidance for considering estimated prepayments as described above is applied If the call option is not exercised at the earliest call date the yield is reset to the effective yield using the payment terms of the security If the security has more than one call date and the premium was amortized to a call price greater than the next call price any excess of the amortized cost basis over the amount repayable at the next call date will be amortized to that date If there are no other call dates any excess of the amortized cost basis over the par amount will be amortized to maturity Discounts on purchased callable debt securities will continue to be amortized to the securityrsquos maturity date The ASU is effective for public business entities for fiscal years and interim

periods within those fiscal years beginning after December 15 2018 For all other entities the ASU is effective for fiscal years beginning after December 15 2019 and interim periods within fiscal years beginning after December 15 2020 Earlier application is permitted for all entities including adoption in an interim period If an entity early adopts the ASU in an interim period any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period The Funds have adopted the ASU The adoption of the ASU did not have a material impact on the financial statements

We have audited the accompanying statements of assets and liabilities of two separate portfolios of Northern Funds comprising the Bond Index Fund and US Treasury Index Fund (collectively the ldquoFundsrdquo) including the schedules of investments as of March 31 2020 the related statements of operations for the year then ended the statements of changes in net assets for each of the two years in the period then ended the financial highlights for each of the five years in the period then ended and the related notes In our opinion the financial statements and financial highlights present fairly in all material respects the financial position of each of the two portfolios constituting the Northern Funds as of March 31 2020 and the results of their operations for the year then ended the changes in their net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended in conformity with accounting principles generally accepted in the United States of America

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fundsrsquo management Our responsibility is to express an opinion on the Fundsrsquo financial statements and financial highlights based on our audits We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Funds in accordance with the US federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB

We conducted our audits in accordance with the standards of the PCAOB Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement whether due to error or fraud The Funds are not required to have nor were we engaged to perform an audit of their internal control over financial reporting As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fundsrsquo internal control over financial reporting Accordingly we express no such opinion

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights whether due to error or fraud and performing procedures that respond to those risks Such procedures included examining on a test basis evidence regarding the amounts and disclosures in the financial statements and financial highlights Our audits also included evaluating the accounting principles used and significant estimates made by management as well as evaluating the overall presentation of the financial statements and financial highlights Our procedures included confirmation of securities owned as of March 31 2020 by correspondence with the custodian and brokers when replies were not received from brokers we performed other auditing procedures We believe that our audits provide a reasonable basis for our opinion

Each Fund has adopted and implemented a Liquidity Risk Management Program (the ldquoProgramrdquo) as required by rule 22e-4 under the Investment Company Act of 1940 The Program seeks to assess manage and review each Fundrsquos Liquidity Risk ldquoLiquidity Riskrdquo is defined as the risk that a Fund could not meet requests to redeem shares issued by the Fund without significant dilution of remaining investorsrsquo interest in the Fund

The Board has appointed Northern Trust Investments Inc (ldquoNTIrdquo) the investment adviser to the Funds as the program administrator for the Program NTI has delegated oversight of the Program to the Northern Trust Asset Management Credit amp Liquidity Risk Committee (the ldquoCommitteerdquo)

At a meeting held on November 13-14 2019 the Board received and reviewed the annual written report of the Committee on behalf of NTI (the ldquoReportrdquo) concerning the operation of the Program for the period from December 1 2018 to September 30 2019 (the ldquoReporting Periodrdquo) The Report addressed the operation of the Program and assessed its adequacy and effectiveness of implementation

The Report summarized the operation of the Program and the information and factors considered by the Committee in reviewing the adequacy and effectiveness of the Programrsquos implementation with respect to each Fund Such information and factors included among other things (i) the liquidity risk framework used to assess manage and periodically review each Fundrsquos liquidity risk and the results of this assessment (ii) the methodology and inputs used to classify the liquidity of each Fundrsquos portfolio investments and the Committeersquos assessment that each Fundrsquos strategy is appropriate for an open-end mutual fund (iii) that each Fund held primarily highly liquid assets (investments that the Fund anticipates can be converted to cash within 3 business days or less in current market conditions without significantly changing their market value) (iv) that none of the Funds required the establishment of a highly liquid investment minimum and the methodology for that determination (v) confirmation that none of the Funds had breached the 15 maximum illiquid security threshold (investments that cannot be sold or disposed of in seven days or less in current market conditions without the sale of the investment significantly changing the market value of the investment) and the procedures for monitoring compliance with the limit and (vi) historical information regarding redemptions and shareholder concentration in each Fund The Report also summarized the changes made to the Program over the course of the year

Based on the review the Report concluded that the Program was being effectively implemented and that the Program was reasonably designed to assess and manage each Fundrsquos liquidity risk

There can be no assurance that the Program will achieve its objectives under all circumstances in the future Please refer to your Fundrsquos prospectus for more information regarding the Fundrsquos exposure to liquidity risk and other risks to which it may be subject

As a shareholder of the Funds you incur two types of costs (1) transaction costs if any and (2) 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 the ongoing costs of investing in other mutual funds

The Example is based on an investment of $1000 invested at the beginning of the period and held for the entire period October 1 2019 through March 31 2020

AC T UA L E X P E N S E S

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 $1000 (for example an $8600 account value divided by $1000 = 86) then multiply the result by the number in the first line under the heading entitled Expenses Paid 1012019 - 3312020 to estimate the expenses you paid on your account during this period

H Y P OT H E T I C A L E X A M P L E F O R C O M PA R I S O N P U R P O S E S

The second line in the tables below provides information about hypothetical account values and hypothetical expenses based on the Fundsrsquo actual expense ratios and an assumed rate of return of 5 percent per year before expenses which is not the Fundsrsquo 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 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 or other costs such as advisory fees related to affiliated money market fund investments but shareholders of other funds may incur such costs If these fees were included your costs would have been higher The information also does not reflect reimbursements on advisory fees incurred in connection with the investment of uninvested cash in affiliated money market funds (See page 92) which may result in different expense ratios in the Financial Highlights 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

1 Fixed Income Market Risk The market values of fixed-income securities owned by the Fund may decline at times sharply and unpredictably Fixed income securities may experience increased volatility illiquidity or other potentially adverse effects in response to changing market conditions inflation changes in interest rates or lack of liquidity in markets which may be caused by numerous factors including but not limited to local or regional events such as war acts of terrorism the spread of infectious illness or other public health issues recessions or other events or adverse investor sentiment

2 Tracking Risk The Fundrsquos performance may vary substantially from the performance of the benchmark index it tracks as a result of share purchases and redemptions transaction costs expenses and other factors

3 US Government Securities Risk There is a risk that the US government will not provide financial support to its agencies instrumentalities or sponsored enterprises if it is not obligated to do so by law Many US government securities purchased by the Fund are not backed by the full faith and credit of the United States It is possible that the issuers of such securities will not have the funds to meet their payment obligations in the future

4 Interest RateMaturity Risk Securities with longer maturities tend to be more sensitive to changes in interest rates causing them to be more volatile than securities with shorter maturities Securities with shorter maturities tend to provide lower returns and be less volatile than securities with longer maturities Changing interest rates may have unpredictable effects on the markets and the Fundrsquos investments A low or declining interest rate environment poses risks to the Fundrsquos performance including the risk that proceeds from prepaid or maturing instruments may have to be reinvested at a lower interest rate Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund

Credit quality ratings are based on the conservative average of Moodyrsquos SampP Global and Fitch ratings If ratings from all three rating agencies disagree the model assigns the middle rating to the security If two of the three agree the model assigns the rating from those two to the security If none of these three rating agencies has assigned a rating the Fund will assign a rating of not rated The ratings expressed in SampP Globalrsquos nomenclature range from AAA (extremely strong capacity to meet its financial commitment) to D (in default) Short-term ratings expressed in SampP Globalrsquos nomenclature range from A-1 (obligorrsquos capacity to meet its financial commitment on the obligation is strong) to D (in default) The ratings represent the rating agenciesrsquo opinions of the quality of the securities they rate Ratings are relative and subjective and are not absolute standards of quality

Various inputs are used in determining the value of the Fundrsquos 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 (eg quoted prices in active markets for similar securities securities valuations based on commonly quoted benchmark interest rates and yield curves maturities ratings andor securities indices) Level 3 - Significant unobservable inputs (eg 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 Fundrsquos investments by the above fair value hierarchy as of March 31 2020

Credit quality ratings are based on the conservative average of Moodyrsquos SampP Global and Fitch ratings If ratings from all three rating agencies disagree the model assigns the middle rating to the security If two of the three agree the model assigns the rating from those two to the security If none of these three rating agencies has assigned a rating the Fund will assign a rating of not rated The ratings expressed in SampP Globalrsquos nomenclature range from AAA (extremely strong capacity to meet its financial commitment) to D (in default) Short-term ratings expressed in SampP Globalrsquos nomenclature range from A-1 (obligorrsquos capacity to meet its financial commitment on the obligation is strong) to D (in default) The ratings represent the rating agenciesrsquo opinions of the quality of the securities they rate Ratings are relative and subjective and are not absolute standards of quality

Various inputs are used in determining the value of the Fundrsquos 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 (eg quoted prices in active markets for similar securities securities valuations based on commonly quoted benchmark interest rates and yield curves maturities ratings andor securities indices) Level 3 - Significant unobservable inputs (eg information about assumptions including risk market participants would use in pricing a security)

Northern Funds (the ldquoTrustrdquo) is a Delaware statutory trust and is registered under the Investment Company Act of 1940 as amended (the ldquo1940 Actrdquo) as an open-end management investment company The Trust offers 43 funds as of March 31 2020 each with its own investment objective (eg long-term capital appreciation total return or income consistent with preservation of capital) The Bond Index and US Treasury Index Funds (each a ldquoFundrdquo and collectively the ldquoFundsrdquo) are separate diversified investment portfolios of the Trust Each of the Funds is presented herein

Northern Trust Investments Inc (ldquoNTIrdquo) a subsidiary of The Northern Trust Company (ldquoNorthern Trustrdquo) serves as the investment adviser and administrator for each of the Funds Northern Trust serves as the custodian transfer agent and sub-administrator for the Trust Northern Funds Distributors LLC not an affiliate of NTI is the Trustrsquos distributor

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

The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of their financial statements These policies are in conformity with accounting principles generally accepted in the United States of America (ldquoUS GAAPrdquo) The preparation of financial statements in conformity with US 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

The net asset value (ldquoNAVrdquo) of each Fund is determined daily as of the close of regular trading on the New York Stock Exchange (ldquoNYSErdquo) generally 300 PM Central Time on each day the NYSE is open for trading

A) VALUATION OF SECURITIES AND DERIVATIVE CONTRACTS

Securities are valued at their fair value Equity securities traded on United States (ldquoUSrdquo) securities exchanges or in the NASDAQ National Market System are principally valued at the regular trading session closing price (generally 300 PM Central Time) on the exchange or market in which such securities are principally traded If any such security is not traded on a valuation date it is valued at the most recent quoted bid price Over-the-counter securities not reported in the NASDAQ National Market System are also generally valued at the most recent quoted bid price Fixed income securities however may be valued on the basis of evaluated prices provided by the Fundsrsquo approved independent third-party pricing services when such prices are believed to

reflect the fair value of such securities or broker provided prices Such prices may be determined by taking into account other similar securitiesrsquo prices yields maturities call features ratings prepayment speeds credit risks cash flows institutional size trading in similar groups of securities and developments related to specific securities

The values of securities of foreign issuers are generally based upon market quotations which depending upon local convention or regulation may be the last sale price the last bid price or the mean between the last bid and asked price as of in each case the close of the appropriate exchange or other designated time Foreign fixed income securities however may like domestic fixed income securities be valued based on evaluated prices provided by independent pricing services when such prices are believed to reflect the fair value of such securities

Shares of open-end investment companies other than exchange-traded funds are valued at their NAV Short-term investments with a maturity of 60 days or less are valued at their amortized cost which NTI as authorized by the Trustrsquos Board of Trustees (the ldquoBoardrdquo) has determined approximates fair value

Any securities for which market quotations are not readily available or are believed to be incorrect are valued at fair value as determined in good faith by NTI under the supervision of the Board The Trust in its discretion may make adjustments to the prices of securities held by a Fund if an event occurs after the publication of fair values normally used by a Fund but before the time as of which the Fund calculates its NAV depending on the nature and significance of the event consistent with applicable regulatory guidance and US GAAP This may occur particularly with respect to certain foreign securities held by a Fund in which case the Trust may use adjustment factors obtained from an independent evaluation service that are intended to reflect more accurately the fair value of those securities as of the time the Fundrsquos NAV is calculated

The use of fair valuation involves the risk that the values used by the Funds 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) FUTURES CONTRACTS Certain Funds invest in long or short exchange-traded futures contracts for hedging purposes to increase total return (ie for speculative purposes) or to maintain liquidity to meet potential shareholder redemptions to invest cash balances or dividends or to minimize trading costs When used as a hedge a Fund may sell a futures contract in order to offset a decrease in the fair value of its portfolio securities that might otherwise result from a market decline A Fund may do so either to hedge the value of its portfolio securities as a whole or to protect against declines occurring prior to sales of securities in the value of the securities to be sold Conversely a Fund may purchase a futures contract as a hedge in anticipation of purchases of securities In addition a Fund may utilize futures contracts in

F I X E D I N C O M E I N D E X F U N D S

MARCH 31 2020

anticipation of changes in the composition of its portfolio holdings A Fund bears the market risk arising from changes in the value of these financial instruments At the time a Fund enters into a futures contract it is generally required to make a margin deposit with the custodian of a specified amount of liquid assets Futures are marked-to-market each day with the change in value reflected in the unrealized gains or losses Risk may arise as a result of the potential inability of the counterparties to meet the terms of their contracts Credit risk is mitigated to the extent that the exchange on which a particular futures contract is traded assumes the risk of a counterparty defaulting on its obligations under the contract The Statements of Operations include any realized gains or losses on closed futures contracts in Net realized gains (losses) on futures contracts and any unrealized gains or losses on open futures contracts in Net change in unrealized appreciation (depreciation) on futures contracts

C) WHEN-ISSUEDDELAYED DELIVERY SECURITIES Certain Funds purchase securities with delivery or payment to occur at a later date beyond the normal settlement period At the time a Fund enters into the commitment to purchase a security the transaction is recorded and the value of the commitment is reflected in the NAV The value of the commitment may vary with market fluctuations No interest accrues to the Fund until settlement takes place At the time a Fund enters into this type of transaction it is required to segregate collateral of cash or liquid assets having a fair value at least equal to the amount of the commitment The Funds identify securities as segregated with a value that meets or exceeds the value of the commitments When-issued securities at March 31 2020 if any are noted in each Fundrsquos Schedule of Investments and in aggregate as Payable for when-issued securities in each Fundrsquos Statement of Assets and Liabilities

On January 6 2014 the Bond Index Fund entered into Master Securities Forward Transaction Agreements (ldquoMSFTArdquo) with certain counterparties pursuant to which each party has agreed to pledge cash andor securities as collateral to secure the repayment of its obligations to the other party under the MSFTA At March 31 2020 the Bond Index Fund received collateral from a broker in the form of a US Treasury Note The value amounted to approximately $282000 which is not included in the Statements of Assets and Liabilities No collateral has been pledged by the Bond Index Fund as of March 31 2020

D) MORTGAGE DOLLAR ROLLS Certain Funds enter into mortgage ldquodollar rollsrdquo in which a Fund sells securities for delivery in the future (generally within 30 days) and simultaneously contracts with the same counterparty to repurchase other mortgage securities on a specified future date During the roll period a Fund loses the right to receive principal and interest paid on the securities sold However a Fund would benefit to the extent of any difference between the price received for the securities sold and the lower forward price for the future purchase

For financial reporting and tax purposes the Funds treat mortgage dollar rolls as two separate transactions one involving the purchase of a security and a separate transaction involving a sale

E) INVESTMENT TRANSACTIONS AND INCOME Investment transactions are recorded as of the trade date The Funds determine the gain or loss realized from investment transactions by using an identified cost basis method Interest income is recognized on an accrual basis and includes amortization of premiums and accretion of discounts using the effective yield method The interest rates reflected in the Schedules of Investments represent the stated coupon rate annualized yield on date of purchase for discount notes the current reset rate for floating rate securities the 7-day yield for money market funds or for interest-only or principal-only securities the current effective yield Cost of investments includes amortization of premiums and accretion of discounts if any Dividend income is recognized on the ex-dividend date The Fundsrsquo income may be subject to certain state and local taxes

F) EXPENSES Each Fund is charged for those expenses that are directly attributable to that Fund Expenses incurred which do not specifically relate to an individual Fund generally are allocated among all Funds in the Trust in proportion to each Fundrsquos relative net assets

G) DISTRIBUTIONS TO SHAREHOLDERS Distributions of dividends from net investment income if any are declared and paid as follows

DECLARATION PAYMENT FREQUENCY FREQUENCY

Bond Index Daily Monthly

US Treasury Index Daily 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

Income dividends and capital gains distributions are determined in accordance with federal income tax regulations Such amounts may differ from income and capital gains recorded in accordance with US GAAP Accordingly the Funds may periodically make reclassifications among certain of their capital accounts to reflect differences between financial reporting and federal income tax basis distributions The reclassifications are reported in order to reflect the tax treatment for certain permanent differences that exist between income tax regulations and US GAAP These reclassifications relate to paydowns These reclassifications have no impact on the net assets or the NAVs per share of the Funds

On March 30 2017 the FASB issued Accounting Standards Update (ldquoASUrdquo) 2017-08 ldquoPremium Amortization on Purchased Callable Debt Securitiesrdquo (the ldquoASUrdquo) which amends the amortization period for certain purchased callable debt securities held at premium shortening such period to the earliest call date The new guidance requires an entity to amortize the premium on a callable debt security within its scope to the earliest call date unless the guidance for considering estimated prepayments as described above is applied If the call option is not exercised at the earliest call date the yield is reset to the effective yield using the payment terms of the security If the security has more than one call date and the premium was amortized to a call price greater than the next call price any excess of the amortized cost basis over the amount repayable at the next call date will be amortized to that date If there are no other call dates any excess of the amortized cost basis over the par amount will be amortized to maturity Discounts on purchased callable debt securities will continue to be amortized to the securityrsquos maturity date The ASU is effective for public business entities for fiscal years and interim

periods within those fiscal years beginning after December 15 2018 For all other entities the ASU is effective for fiscal years beginning after December 15 2019 and interim periods within fiscal years beginning after December 15 2020 Earlier application is permitted for all entities including adoption in an interim period If an entity early adopts the ASU in an interim period any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period The Funds have adopted the ASU The adoption of the ASU did not have a material impact on the financial statements

Each Fund has adopted and implemented a Liquidity Risk Management Program (the ldquoProgramrdquo) as required by rule 22e-4 under the Investment Company Act of 1940 The Program seeks to assess manage and review each Fundrsquos Liquidity Risk ldquoLiquidity Riskrdquo is defined as the risk that a Fund could not meet requests to redeem shares issued by the Fund without significant dilution of remaining investorsrsquo interest in the Fund

The Board has appointed Northern Trust Investments Inc (ldquoNTIrdquo) the investment adviser to the Funds as the program administrator for the Program NTI has delegated oversight of the Program to the Northern Trust Asset Management Credit amp Liquidity Risk Committee (the ldquoCommitteerdquo)

At a meeting held on November 13-14 2019 the Board received and reviewed the annual written report of the Committee on behalf of NTI (the ldquoReportrdquo) concerning the operation of the Program for the period from December 1 2018 to September 30 2019 (the ldquoReporting Periodrdquo) The Report addressed the operation of the Program and assessed its adequacy and effectiveness of implementation

The Report summarized the operation of the Program and the information and factors considered by the Committee in reviewing the adequacy and effectiveness of the Programrsquos implementation with respect to each Fund Such information and factors included among other things (i) the liquidity risk framework used to assess manage and periodically review each Fundrsquos liquidity risk and the results of this assessment (ii) the methodology and inputs used to classify the liquidity of each Fundrsquos portfolio investments and the Committeersquos assessment that each Fundrsquos strategy is appropriate for an open-end mutual fund (iii) that each Fund held primarily highly liquid assets (investments that the Fund anticipates can be converted to cash within 3 business days or less in current market conditions without significantly changing their market value) (iv) that none of the Funds required the establishment of a highly liquid investment minimum and the methodology for that determination (v) confirmation that none of the Funds had breached the 15 maximum illiquid security threshold (investments that cannot be sold or disposed of in seven days or less in current market conditions without the sale of the investment significantly changing the market value of the investment) and the procedures for monitoring compliance with the limit and (vi) historical information regarding redemptions and shareholder concentration in each Fund The Report also summarized the changes made to the Program over the course of the year

Based on the review the Report concluded that the Program was being effectively implemented and that the Program was reasonably designed to assess and manage each Fundrsquos liquidity risk

There can be no assurance that the Program will achieve its objectives under all circumstances in the future Please refer to your Fundrsquos prospectus for more information regarding the Fundrsquos exposure to liquidity risk and other risks to which it may be subject

As a shareholder of the Funds you incur two types of costs (1) transaction costs if any and (2) 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 the ongoing costs of investing in other mutual funds

The Example is based on an investment of $1000 invested at the beginning of the period and held for the entire period October 1 2019 through March 31 2020

AC T UA L E X P E N S E S

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 $1000 (for example an $8600 account value divided by $1000 = 86) then multiply the result by the number in the first line under the heading entitled Expenses Paid 1012019 - 3312020 to estimate the expenses you paid on your account during this period

H Y P OT H E T I C A L E X A M P L E F O R C O M PA R I S O N P U R P O S E S

The second line in the tables below provides information about hypothetical account values and hypothetical expenses based on the Fundsrsquo actual expense ratios and an assumed rate of return of 5 percent per year before expenses which is not the Fundsrsquo 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 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 or other costs such as advisory fees related to affiliated money market fund investments but shareholders of other funds may incur such costs If these fees were included your costs would have been higher The information also does not reflect reimbursements on advisory fees incurred in connection with the investment of uninvested cash in affiliated money market funds (See page 92) which may result in different expense ratios in the Financial Highlights 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

1 Fixed Income Market Risk The market values of fixed-income securities owned by the Fund may decline at times sharply and unpredictably Fixed income securities may experience increased volatility illiquidity or other potentially adverse effects in response to changing market conditions inflation changes in interest rates or lack of liquidity in markets which may be caused by numerous factors including but not limited to local or regional events such as war acts of terrorism the spread of infectious illness or other public health issues recessions or other events or adverse investor sentiment

2 Tracking Risk The Fundrsquos performance may vary substantially from the performance of the benchmark index it tracks as a result of share purchases and redemptions transaction costs expenses and other factors

3 US Government Securities Risk There is a risk that the US government will not provide financial support to its agencies instrumentalities or sponsored enterprises if it is not obligated to do so by law Many US government securities purchased by the Fund are not backed by the full faith and credit of the United States It is possible that the issuers of such securities will not have the funds to meet their payment obligations in the future

4 Interest RateMaturity Risk Securities with longer maturities tend to be more sensitive to changes in interest rates causing them to be more volatile than securities with shorter maturities Securities with shorter maturities tend to provide lower returns and be less volatile than securities with longer maturities Changing interest rates may have unpredictable effects on the markets and the Fundrsquos investments A low or declining interest rate environment poses risks to the Fundrsquos performance including the risk that proceeds from prepaid or maturing instruments may have to be reinvested at a lower interest rate Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund

Credit quality ratings are based on the conservative average of Moodyrsquos SampP Global and Fitch ratings If ratings from all three rating agencies disagree the model assigns the middle rating to the security If two of the three agree the model assigns the rating from those two to the security If none of these three rating agencies has assigned a rating the Fund will assign a rating of not rated The ratings expressed in SampP Globalrsquos nomenclature range from AAA (extremely strong capacity to meet its financial commitment) to D (in default) Short-term ratings expressed in SampP Globalrsquos nomenclature range from A-1 (obligorrsquos capacity to meet its financial commitment on the obligation is strong) to D (in default) The ratings represent the rating agenciesrsquo opinions of the quality of the securities they rate Ratings are relative and subjective and are not absolute standards of quality

Various inputs are used in determining the value of the Fundrsquos 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 (eg quoted prices in active markets for similar securities securities valuations based on commonly quoted benchmark interest rates and yield curves maturities ratings andor securities indices) Level 3 - Significant unobservable inputs (eg 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 Fundrsquos investments by the above fair value hierarchy as of March 31 2020

Northern Funds (the ldquoTrustrdquo) is a Delaware statutory trust and is registered under the Investment Company Act of 1940 as amended (the ldquo1940 Actrdquo) as an open-end management investment company The Trust offers 43 funds as of March 31 2020 each with its own investment objective (eg long-term capital appreciation total return or income consistent with preservation of capital) The Bond Index and US Treasury Index Funds (each a ldquoFundrdquo and collectively the ldquoFundsrdquo) are separate diversified investment portfolios of the Trust Each of the Funds is presented herein

Northern Trust Investments Inc (ldquoNTIrdquo) a subsidiary of The Northern Trust Company (ldquoNorthern Trustrdquo) serves as the investment adviser and administrator for each of the Funds Northern Trust serves as the custodian transfer agent and sub-administrator for the Trust Northern Funds Distributors LLC not an affiliate of NTI is the Trustrsquos distributor

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

The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of their financial statements These policies are in conformity with accounting principles generally accepted in the United States of America (ldquoUS GAAPrdquo) The preparation of financial statements in conformity with US 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

The net asset value (ldquoNAVrdquo) of each Fund is determined daily as of the close of regular trading on the New York Stock Exchange (ldquoNYSErdquo) generally 300 PM Central Time on each day the NYSE is open for trading

A) VALUATION OF SECURITIES AND DERIVATIVE CONTRACTS

Securities are valued at their fair value Equity securities traded on United States (ldquoUSrdquo) securities exchanges or in the NASDAQ National Market System are principally valued at the regular trading session closing price (generally 300 PM Central Time) on the exchange or market in which such securities are principally traded If any such security is not traded on a valuation date it is valued at the most recent quoted bid price Over-the-counter securities not reported in the NASDAQ National Market System are also generally valued at the most recent quoted bid price Fixed income securities however may be valued on the basis of evaluated prices provided by the Fundsrsquo approved independent third-party pricing services when such prices are believed to

reflect the fair value of such securities or broker provided prices Such prices may be determined by taking into account other similar securitiesrsquo prices yields maturities call features ratings prepayment speeds credit risks cash flows institutional size trading in similar groups of securities and developments related to specific securities

The values of securities of foreign issuers are generally based upon market quotations which depending upon local convention or regulation may be the last sale price the last bid price or the mean between the last bid and asked price as of in each case the close of the appropriate exchange or other designated time Foreign fixed income securities however may like domestic fixed income securities be valued based on evaluated prices provided by independent pricing services when such prices are believed to reflect the fair value of such securities

Shares of open-end investment companies other than exchange-traded funds are valued at their NAV Short-term investments with a maturity of 60 days or less are valued at their amortized cost which NTI as authorized by the Trustrsquos Board of Trustees (the ldquoBoardrdquo) has determined approximates fair value

Any securities for which market quotations are not readily available or are believed to be incorrect are valued at fair value as determined in good faith by NTI under the supervision of the Board The Trust in its discretion may make adjustments to the prices of securities held by a Fund if an event occurs after the publication of fair values normally used by a Fund but before the time as of which the Fund calculates its NAV depending on the nature and significance of the event consistent with applicable regulatory guidance and US GAAP This may occur particularly with respect to certain foreign securities held by a Fund in which case the Trust may use adjustment factors obtained from an independent evaluation service that are intended to reflect more accurately the fair value of those securities as of the time the Fundrsquos NAV is calculated

The use of fair valuation involves the risk that the values used by the Funds 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) FUTURES CONTRACTS Certain Funds invest in long or short exchange-traded futures contracts for hedging purposes to increase total return (ie for speculative purposes) or to maintain liquidity to meet potential shareholder redemptions to invest cash balances or dividends or to minimize trading costs When used as a hedge a Fund may sell a futures contract in order to offset a decrease in the fair value of its portfolio securities that might otherwise result from a market decline A Fund may do so either to hedge the value of its portfolio securities as a whole or to protect against declines occurring prior to sales of securities in the value of the securities to be sold Conversely a Fund may purchase a futures contract as a hedge in anticipation of purchases of securities In addition a Fund may utilize futures contracts in

FIXED INCOME INDEX FUNDS 88 NORTHERN FUNDS ANNUAL REPORT

F I X E D I N C O M E I N D E X F U N D S

MARCH 31 2020

anticipation of changes in the composition of its portfolio holdings A Fund bears the market risk arising from changes in the value of these financial instruments At the time a Fund enters into a futures contract it is generally required to make a margin deposit with the custodian of a specified amount of liquid assets Futures are marked-to-market each day with the change in value reflected in the unrealized gains or losses Risk may arise as a result of the potential inability of the counterparties to meet the terms of their contracts Credit risk is mitigated to the extent that the exchange on which a particular futures contract is traded assumes the risk of a counterparty defaulting on its obligations under the contract The Statements of Operations include any realized gains or losses on closed futures contracts in Net realized gains (losses) on futures contracts and any unrealized gains or losses on open futures contracts in Net change in unrealized appreciation (depreciation) on futures contracts

C) WHEN-ISSUEDDELAYED DELIVERY SECURITIES Certain Funds purchase securities with delivery or payment to occur at a later date beyond the normal settlement period At the time a Fund enters into the commitment to purchase a security the transaction is recorded and the value of the commitment is reflected in the NAV The value of the commitment may vary with market fluctuations No interest accrues to the Fund until settlement takes place At the time a Fund enters into this type of transaction it is required to segregate collateral of cash or liquid assets having a fair value at least equal to the amount of the commitment The Funds identify securities as segregated with a value that meets or exceeds the value of the commitments When-issued securities at March 31 2020 if any are noted in each Fundrsquos Schedule of Investments and in aggregate as Payable for when-issued securities in each Fundrsquos Statement of Assets and Liabilities

On January 6 2014 the Bond Index Fund entered into Master Securities Forward Transaction Agreements (ldquoMSFTArdquo) with certain counterparties pursuant to which each party has agreed to pledge cash andor securities as collateral to secure the repayment of its obligations to the other party under the MSFTA At March 31 2020 the Bond Index Fund received collateral from a broker in the form of a US Treasury Note The value amounted to approximately $282000 which is not included in the Statements of Assets and Liabilities No collateral has been pledged by the Bond Index Fund as of March 31 2020

D) MORTGAGE DOLLAR ROLLS Certain Funds enter into mortgage ldquodollar rollsrdquo in which a Fund sells securities for delivery in the future (generally within 30 days) and simultaneously contracts with the same counterparty to repurchase other mortgage securities on a specified future date During the roll period a Fund loses the right to receive principal and interest paid on the securities sold However a Fund would benefit to the extent of any difference between the price received for the securities sold and the lower forward price for the future purchase

For financial reporting and tax purposes the Funds treat mortgage dollar rolls as two separate transactions one involving the purchase of a security and a separate transaction involving a sale

E) INVESTMENT TRANSACTIONS AND INCOME Investment transactions are recorded as of the trade date The Funds determine the gain or loss realized from investment transactions by using an identified cost basis method Interest income is recognized on an accrual basis and includes amortization of premiums and accretion of discounts using the effective yield method The interest rates reflected in the Schedules of Investments represent the stated coupon rate annualized yield on date of purchase for discount notes the current reset rate for floating rate securities the 7-day yield for money market funds or for interest-only or principal-only securities the current effective yield Cost of investments includes amortization of premiums and accretion of discounts if any Dividend income is recognized on the ex-dividend date The Fundsrsquo income may be subject to certain state and local taxes

F) EXPENSES Each Fund is charged for those expenses that are directly attributable to that Fund Expenses incurred which do not specifically relate to an individual Fund generally are allocated among all Funds in the Trust in proportion to each Fundrsquos relative net assets

G) DISTRIBUTIONS TO SHAREHOLDERS Distributions of dividends from net investment income if any are declared and paid as follows

DECLARATION PAYMENT FREQUENCY FREQUENCY

Bond Index Daily Monthly

US Treasury Index Daily 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

Income dividends and capital gains distributions are determined in accordance with federal income tax regulations Such amounts may differ from income and capital gains recorded in accordance with US GAAP Accordingly the Funds may periodically make reclassifications among certain of their capital accounts to reflect differences between financial reporting and federal income tax basis distributions The reclassifications are reported in order to reflect the tax treatment for certain permanent differences that exist between income tax regulations and US GAAP These reclassifications relate to paydowns These reclassifications have no impact on the net assets or the NAVs per share of the Funds

H) FEDERAL INCOME TAXES No provision for federal income taxes has been made since each Fundrsquos policy is to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986 as amended (the ldquoCoderdquo) applicable to regulated investment companies and to distribute each year substantially all of its taxable income and capital gains to its shareholders

On March 30 2017 the FASB issued Accounting Standards Update (ldquoASUrdquo) 2017-08 ldquoPremium Amortization on Purchased Callable Debt Securitiesrdquo (the ldquoASUrdquo) which amends the amortization period for certain purchased callable debt securities held at premium shortening such period to the earliest call date The new guidance requires an entity to amortize the premium on a callable debt security within its scope to the earliest call date unless the guidance for considering estimated prepayments as described above is applied If the call option is not exercised at the earliest call date the yield is reset to the effective yield using the payment terms of the security If the security has more than one call date and the premium was amortized to a call price greater than the next call price any excess of the amortized cost basis over the amount repayable at the next call date will be amortized to that date If there are no other call dates any excess of the amortized cost basis over the par amount will be amortized to maturity Discounts on purchased callable debt securities will continue to be amortized to the securityrsquos maturity date The ASU is effective for public business entities for fiscal years and interim

periods within those fiscal years beginning after December 15 2018 For all other entities the ASU is effective for fiscal years beginning after December 15 2019 and interim periods within fiscal years beginning after December 15 2020 Earlier application is permitted for all entities including adoption in an interim period If an entity early adopts the ASU in an interim period any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period The Funds have adopted the ASU The adoption of the ASU did not have a material impact on the financial statements

Each Fund has adopted and implemented a Liquidity Risk Management Program (the ldquoProgramrdquo) as required by rule 22e-4 under the Investment Company Act of 1940 The Program seeks to assess manage and review each Fundrsquos Liquidity Risk ldquoLiquidity Riskrdquo is defined as the risk that a Fund could not meet requests to redeem shares issued by the Fund without significant dilution of remaining investorsrsquo interest in the Fund

The Board has appointed Northern Trust Investments Inc (ldquoNTIrdquo) the investment adviser to the Funds as the program administrator for the Program NTI has delegated oversight of the Program to the Northern Trust Asset Management Credit amp Liquidity Risk Committee (the ldquoCommitteerdquo)

At a meeting held on November 13-14 2019 the Board received and reviewed the annual written report of the Committee on behalf of NTI (the ldquoReportrdquo) concerning the operation of the Program for the period from December 1 2018 to September 30 2019 (the ldquoReporting Periodrdquo) The Report addressed the operation of the Program and assessed its adequacy and effectiveness of implementation

The Report summarized the operation of the Program and the information and factors considered by the Committee in reviewing the adequacy and effectiveness of the Programrsquos implementation with respect to each Fund Such information and factors included among other things (i) the liquidity risk framework used to assess manage and periodically review each Fundrsquos liquidity risk and the results of this assessment (ii) the methodology and inputs used to classify the liquidity of each Fundrsquos portfolio investments and the Committeersquos assessment that each Fundrsquos strategy is appropriate for an open-end mutual fund (iii) that each Fund held primarily highly liquid assets (investments that the Fund anticipates can be converted to cash within 3 business days or less in current market conditions without significantly changing their market value) (iv) that none of the Funds required the establishment of a highly liquid investment minimum and the methodology for that determination (v) confirmation that none of the Funds had breached the 15 maximum illiquid security threshold (investments that cannot be sold or disposed of in seven days or less in current market conditions without the sale of the investment significantly changing the market value of the investment) and the procedures for monitoring compliance with the limit and (vi) historical information regarding redemptions and shareholder concentration in each Fund The Report also summarized the changes made to the Program over the course of the year

Based on the review the Report concluded that the Program was being effectively implemented and that the Program was reasonably designed to assess and manage each Fundrsquos liquidity risk

There can be no assurance that the Program will achieve its objectives under all circumstances in the future Please refer to your Fundrsquos prospectus for more information regarding the Fundrsquos exposure to liquidity risk and other risks to which it may be subject

As a shareholder of the Funds you incur two types of costs (1) transaction costs if any and (2) 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 the ongoing costs of investing in other mutual funds

The Example is based on an investment of $1000 invested at the beginning of the period and held for the entire period October 1 2019 through March 31 2020

AC T UA L E X P E N S E S

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 $1000 (for example an $8600 account value divided by $1000 = 86) then multiply the result by the number in the first line under the heading entitled Expenses Paid 1012019 - 3312020 to estimate the expenses you paid on your account during this period

H Y P OT H E T I C A L E X A M P L E F O R C O M PA R I S O N P U R P O S E S

The second line in the tables below provides information about hypothetical account values and hypothetical expenses based on the Fundsrsquo actual expense ratios and an assumed rate of return of 5 percent per year before expenses which is not the Fundsrsquo 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 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 or other costs such as advisory fees related to affiliated money market fund investments but shareholders of other funds may incur such costs If these fees were included your costs would have been higher The information also does not reflect reimbursements on advisory fees incurred in connection with the investment of uninvested cash in affiliated money market funds (See page 92) which may result in different expense ratios in the Financial Highlights 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

1 Fixed Income Market Risk The market values of fixed-income securities owned by the Fund may decline at times sharply and unpredictably Fixed income securities may experience increased volatility illiquidity or other potentially adverse effects in response to changing market conditions inflation changes in interest rates or lack of liquidity in markets which may be caused by numerous factors including but not limited to local or regional events such as war acts of terrorism the spread of infectious illness or other public health issues recessions or other events or adverse investor sentiment

2 Tracking Risk The Fundrsquos performance may vary substantially from the performance of the benchmark index it tracks as a result of share purchases and redemptions transaction costs expenses and other factors

3 US Government Securities Risk There is a risk that the US government will not provide financial support to its agencies instrumentalities or sponsored enterprises if it is not obligated to do so by law Many US government securities purchased by the Fund are not backed by the full faith and credit of the United States It is possible that the issuers of such securities will not have the funds to meet their payment obligations in the future

4 Interest RateMaturity Risk Securities with longer maturities tend to be more sensitive to changes in interest rates causing them to be more volatile than securities with shorter maturities Securities with shorter maturities tend to provide lower returns and be less volatile than securities with longer maturities Changing interest rates may have unpredictable effects on the markets and the Fundrsquos investments A low or declining interest rate environment poses risks to the Fundrsquos performance including the risk that proceeds from prepaid or maturing instruments may have to be reinvested at a lower interest rate Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund
