For the period ended May 31, 2026
1. Organization.
Fidelity Limited Term Government Fund (the Fund) is a fund of Fidelity Advisor Series IV (the Trust) and is authorized to issue an unlimited number of shares. Share transactions on the Statement of Changes in Net Assets may contain exchanges between affiliated funds. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.
2. Investments in Fidelity Central Funds.
Funds may invest in Fidelity Central Funds, which are open-end investment companies generally available only to other investment companies and accounts managed by the investment adviser and its affiliates. The Schedule of Investments lists any Fidelity Central Funds held as an investment as of period end, but does not include the underlying holdings of each Fidelity Central Fund. An investing fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.
Based on its investment objective, each Fidelity Central Fund may invest or participate in various investment vehicles or strategies that are similar to those of the investing fund. These strategies are consistent with the investment objectives of the investing fund and may involve certain economic risks which may cause a decline in value of each of the Fidelity Central Funds and thus a decline in the value of the investing fund.

A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission website at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds which contain the significant accounting policies (including investment valuation policies) of those funds, and are not covered by the Report of Independent Registered Public Accounting Firm, are available on the Securities and Exchange Commission website or upon request.
3. Significant Accounting Policies.
The Fund is an investment company and applies the accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 Financial Services - Investment Companies. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. The Fund operates as a single operating segment. The Fund's portfolio management team, part of the investment adviser, serves as the chief operating decision maker (CODM) and directs the Fund's investments in accordance with its investment objective and policies, with support from others responsible for oversight functions. The information reviewed by the CODM is consistent with the Fund's financial statements and financial highlights. Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The Fund's Schedule of Investments lists any underlying mutual funds or exchange-traded funds but does not include the underlying holdings of these funds. The following summarizes the significant accounting policies of the Fund:
Investment Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. The Board of Trustees (the Board) has designated the Fund's investment adviser as the valuation designee responsible for the fair valuation function and performing fair value determinations as needed. The investment adviser has established a Fair Value Committee (the Committee) to carry out the day-to-day fair valuation responsibilities and has adopted policies and procedures to govern the fair valuation process and the activities of the Committee. In accordance with these fair valuation policies and procedures, which have been approved by the Board, the Fund attempts to obtain prices from one or more third party pricing services or brokers to value its investments. When current market prices, quotations or currency exchange rates are not readily available or reliable, investments will be fair valued in good faith by the Committee, in accordance with the policies and procedures. Factors used in determining fair value vary by investment type and may include market or investment specific events, transaction data, estimated cash flows, and market observations of comparable investments. The frequency that the fair valuation procedures are used cannot be predicted and they may be utilized to a significant extent. The Committee manages the Fund's fair valuation practices and maintains the fair valuation policies and procedures. The Fund's investment adviser reports to the Board information regarding the fair valuation process and related material matters.
The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:
Level 1 - unadjusted quoted prices in active markets for identical investments
Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)
Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available)
Valuation techniques used to value the Fund's investments by major category are as follows:
Debt securities, including restricted securities, are valued based on evaluated prices received from third party pricing services or from brokers who make markets in such securities. U.S. government and government agency obligations are valued by pricing services who utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. Collateralized mortgage obligations, commercial mortgage securities and U.S. government agency mortgage securities are valued by pricing services who utilize matrix pricing which considers prepayment speed assumptions, attributes of the collateral, yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. Swaps are marked-to-market daily based on valuations from third party pricing services, registered derivatives clearing organizations (clearinghouses) or broker-supplied valuations. These pricing sources may utilize inputs such as interest rate curves, credit spread curves, default possibilities and recovery rates. When independent prices are unavailable or unreliable, debt securities and swaps may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing services. Debt securities and swaps are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.
Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Options traded over-the-counter are valued using service or broker-supplied valuations and are categorized as Level 2 in the hierarchy. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.
Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. The aggregate value of investments by input level as of May 31, 2026 is included at the end of the Fund's Schedule of Investments.
Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time and includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost and include proceeds received from litigation. Income and capital gain distributions from Fidelity Central Funds, if any, are recorded on the ex-dividend date. Interest income is accrued as earned and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.
Expenses. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expenses included in the accompanying financial statements reflect the expenses of that fund and do not include any expenses associated with any underlying mutual funds or exchange-traded funds. Although not included in a fund's expenses, a fund indirectly bears its proportionate share of these expenses through the net asset value of each underlying mutual fund or exchange-traded fund. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.
Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, including distributing substantially all of its taxable income and realized gains. As a result, no provision for U.S. Federal income taxes is required. The Fund files a U.S. federal tax return, in addition to state and local tax returns as required. The Fund's federal income tax returns are subject to examination by the Internal Revenue Service (IRS) for a period of three fiscal years after they are filed. State and local tax returns may be subject to examination for an additional fiscal year depending on the jurisdiction.
Distributions are declared and recorded daily and paid monthly from net investment income. Distributions from realized gains, if any, are declared and recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.
Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Capital accounts are not adjusted for temporary book-tax differences which will reverse in a subsequent period.
Book-tax differences are primarily due to futures contracts, swaps, market discount, capital loss carryforwards, and losses deferred due to wash sales and futures contracts.
As of period end, the cost and unrealized appreciation (depreciation) in securities, and derivatives if applicable, for federal income tax purposes were as follows:
Gross unrealized appreciation
$1,293,307
Gross unrealized depreciation
(1,026,021)
Net unrealized appreciation (depreciation)
$267,286
Tax cost
$161,917,303
Capital loss carryforwards are only available to offset future capital gains of the Fund to the extent provided by regulations and may be limited. The capital loss carryforward information presented below, including any applicable limitation, is estimated as of prior fiscal period end and is subject to adjustment.

Delayed Delivery Transactions and When-Issued Securities. During the period, certain Funds transacted in securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. Securities purchased on a delayed delivery or when-issued basis are identified as such in the Schedule of Investments. Compensation for interest forgone in the purchase of a delayed delivery or when-issued debt security may be received. With respect to purchase commitments, each applicable Fund identifies securities as segregated in its records with a value at least equal to the amount of the commitment. Payables and receivables associated with the purchases and sales of delayed delivery securities having the same coupon, settlement date and broker are offset. Delayed delivery or when-issued securities that have been purchased from and sold to different brokers are reflected as both payables and receivables in the Statement of Assets and Liabilities under the caption "Delayed delivery", as applicable. Losses may arise due to changes in the value of the underlying securities or if the counterparty does not perform under the contract's terms, or if the issuer does not issue the securities due to political, economic, or other factors.
To-Be-Announced (TBA) Securities and Mortgage Dollar Rolls. TBA securities involve buying or selling mortgage-backed securities (MBS) on a forward commitment basis. A TBA transaction typically does not designate the actual security to be delivered and only includes an approximate principal amount; however delivered securities must meet specified terms defined by industry guidelines, including issuer, rate and current principal amount outstanding on underlying mortgage pools. Funds may enter into a TBA transaction with the intent to take possession of or deliver the underlying MBS, or a fund may elect to extend the settlement by entering into either a mortgage or reverse mortgage dollar roll. Mortgage dollar rolls are transactions where a fund sells TBA securities and simultaneously agrees to repurchase MBS on a later date at a lower price and with the same counterparty. Reverse mortgage dollar rolls involve the purchase and simultaneous agreement to sell TBA securities on a later date at a lower price. Transactions in mortgage dollar rolls and reverse mortgage dollar rolls are accounted for as purchases and sales and may result in an increase to a fund's portfolio turnover rate.
Purchases and sales of TBA securities involve risks similar to those discussed above for delayed delivery and when-issued securities. Also, if the counterparty in a mortgage dollar roll or a reverse mortgage dollar roll transaction files for bankruptcy or becomes insolvent, a fund's right to repurchase or sell securities may be limited. Additionally, when a fund sells TBA securities without already owning or having the right to obtain the deliverable securities (an uncovered forward commitment to sell), it incurs a risk of loss because it could have to purchase the securities at a price that is higher than the price at which it sold them. A fund may be unable to purchase the deliverable securities if the corresponding market is illiquid.
TBA securities subject to a forward commitment to sell at period end are included at the end of the Schedule of Investments under the caption "TBA Sale Commitments." The value of these commitments and proceeds to be received at contractual settlement date are reflected in the Statement of Assets and Liabilities as "TBA sale commitments, at value" and "Receivable for TBA sale commitments," respectively. A fund realizes a gain or loss on settlement, either through the acquisition of an offsetting TBA purchase commitment on or before the sale commitment date, or by delivery of the securities under the commitment.
4. Derivative Instruments.
Risk Exposures and the Use of Derivative Instruments. The Fund's investment objectives allow for various types of derivative instruments, including futures contracts, swaps and options. Derivatives are investments whose value is primarily derived from underlying assets, indices or reference rates and may be transacted on an exchange or over-the-counter (OTC). Derivatives may involve a future commitment to buy or sell a specified asset based on specified terms, to exchange future cash flows at periodic intervals based on a notional principal amount, or for one party to make one or more payments upon the occurrence of specified events in exchange for periodic payments from the other party.
Derivatives were used to increase returns, to gain exposure to certain types of assets and to manage exposure to certain risks as defined below. The success of any strategy involving derivatives depends on analysis of numerous economic factors, and if the strategies for investment do not work as intended, the objectives may not be achieved.
Derivatives were used to increase or decrease exposure to the following risk(s):
Interest Rate Risk
Interest rate risk relates to the fluctuations in the value of interest-bearing securities due to changes in the prevailing levels of market interest rates.
Funds are also exposed to additional risks from investing in derivatives, such as liquidity risk and counterparty credit risk. Liquidity risk is the risk that a fund will be unable to close out the derivative in the open market in a timely manner. Counterparty credit risk is the risk that the counterparty will not be able to fulfill its obligation to a fund. Derivative counterparty credit risk is managed through formal evaluation of the creditworthiness of all potential counterparties. On certain OTC derivatives such as options, a fund attempts to reduce its exposure to counterparty credit risk by entering into an International Swaps and Derivatives Association, Inc. (ISDA) Master Agreement with each of its counterparties. The ISDA Master Agreement gives a fund the right to terminate all transactions traded under such agreement upon the deterioration in the credit quality of the counterparty beyond specified levels. The ISDA Master Agreement gives each party the right, upon an event of default by the other party or a termination of the agreement, to close out all transactions traded under such agreement and to net amounts owed under each transaction to one net payable by one party to the other. To mitigate counterparty credit risk on bi-lateral OTC derivatives, a fund receives collateral in the form of cash or securities once net unrealized appreciation on outstanding derivative contracts under an ISDA Master Agreement exceeds certain applicable thresholds, subject to certain minimum transfer provisions. The collateral received is held in segregated accounts with the custodian bank in accordance with the collateral agreements entered into between a fund, the counterparty and the custodian bank. A fund could experience delays and costs in gaining access to the collateral even though it is held by the custodian bank. The maximum risk of loss to a fund from counterparty credit risk related to bi-lateral OTC derivatives is generally the aggregate unrealized appreciation and unpaid counterparty payments in excess of any collateral pledged by the counterparty to a fund. For OTC written options with upfront premiums received, a fund is obligated to perform and therefore does not have counterparty risk. For OTC written options with premiums to be received at a future date, the maximum risk of loss from counterparty credit risk is the amount of the premium in excess of any collateral pledged by the counterparty. A fund may be required to pledge collateral for the benefit of the counterparties on bi-lateral OTC derivatives in an amount not less than each counterparty's unrealized appreciation on outstanding derivative contracts, subject to certain minimum transfer provisions, and any such pledged collateral is identified in the Schedule of Investments. Exchange-traded contracts are not covered by the ISDA Master Agreement; however counterparty credit risk related to these contracts may be mitigated by the protection provided by the exchange on which they trade. Counterparty credit risk related to centrally cleared swaps may be mitigated by the protection provided by the clearinghouse.
Investing in derivatives may involve greater risks than investing in the underlying assets directly and, to varying degrees, may involve risk of loss in excess of any initial investment and collateral received and amounts recognized in the Statement of Assets and Liabilities. In addition, there may be the risk that the change in value of the derivative contract does not correspond to the change in value of the underlying instrument.
Net Realized Gain (Loss) and Change in Net Unrealized Appreciation (Depreciation) on Derivatives. The table below, which reflects the impacts of derivatives on the financial performance, summarizes the net realized gain (loss) and change in net unrealized appreciation (depreciation) for derivatives during the period as presented in the Statement of Operations.

If there are any open positions at period end, a summary of the value of derivatives by primary risk exposure is included at the end of the Schedule of Investments.
Futures Contracts. A futures contract is an agreement between two parties to buy or sell a specified underlying instrument for a fixed price at a specified future date. Futures contracts were used to manage exposure to the bond market and fluctuations in interest rates.
Upon entering into a futures contract, a fund is required to deposit either cash or securities (initial margin) with a clearing broker in an amount equal to a certain percentage of the face value of the contract. Futures contracts are marked-to-market daily. Subsequent payments from or to a fund are made or as needed depending on the fluctuations in the value of the futures contracts and are recorded as unrealized appreciation or (depreciation). This receivable and/or payable, if any, is included in variation margin on futures contracts in the Statement of Assets and Liabilities. Realized gain or (loss) is recorded upon the expiration or closing of a futures contract. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on futures contracts during the period is presented in the Statement of Operations.
Any open futures contracts at period end are presented in the Schedule of Investments under the caption "Futures Contracts". The notional amount at value reflects each contract's exposure to the underlying instrument or index at period end, and is representative of volume of activity during the period, unless an average notional amount is presented in the table below.
Average Notional Amount ($)
Fidelity Limited Term Government Fund
46,589,358
Any securities deposited to meet initial margin requirements are identified in the Schedule of Investments. Any cash deposited to meet initial margin requirements is presented as segregated cash with brokers for derivative instruments in the Statement of Assets and Liabilities.
Options. Options give the purchaser the right, but not the obligation, to buy (call) or sell (put) an underlying security or financial instrument at an agreed exercise or strike price between or on certain dates. Options obligate the seller (writer) to buy (put) or sell (call) an underlying instrument at the exercise or strike price or cash settle an underlying derivative instrument if the holder exercises the option on or before the expiration date. OTC options, such as swaptions, which are options where the underlying instrument is a swap, were used to manage exposure to fluctuations in interest rates.
Upon entering into an options contract, a fund will pay or receive a premium. Premiums paid on purchased options are reflected as cost of investments and premiums received on written options are reflected as a liability on the Statement of Assets and Liabilities. Certain options may be purchased or written with premiums to be paid or received on a future date. Options are valued daily and any unrealized appreciation (depreciation) is reflected in total accumulated earnings (loss) in the Statement of Assets and Liabilities. When an option is exercised, the cost or proceeds of the underlying instrument purchased or sold is adjusted by the amount of the premium. When an option is closed, a gain or loss is realized depending on whether the proceeds or amount paid for the closing sale transaction is greater or less than the premium received or paid. When an option expires, gains and losses are realized to the extent of premiums received and paid, respectively. The net realized and unrealized gains (losses) on purchased options are included in the Statement of Operations in net realized gain (loss) and change in net unrealized appreciation (depreciation) on investment securities. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on written options are presented in the Statement of Operations.
Any open options at period end are presented in the Schedule of Investments under the captions "Purchased Options," "Purchased Swaptions," "Written Options" and "Written Swaptions," as applicable, and are representative of volume of activity during the period, unless an average notional amount is presented in the table below.

Average Notional Amount ($)
Fidelity Limited Term Government Fund
Purchased Swaptions

Writing puts and buying calls tend to increase exposure to the underlying instrument while buying puts and writing calls tend to decrease exposure to the underlying instrument. For purchased options, risk of loss is limited to the premium paid, and for written options, risk of loss is the change in value in excess of the premium received.
Swaps. A swap is a contract between two parties to exchange future cash flows at periodic intervals based on a notional principal amount. A centrally cleared swap is a transaction executed between a fund and a dealer counterparty, then cleared by a futures commission merchant (FCM) through a clearinghouse. Once cleared, the clearinghouse serves as a central counterparty, with whom a fund exchanges cash flows for the life of the transaction, similar to transactions in futures contracts.
Centrally cleared swaps require a fund to deposit either cash or securities (initial margin) with the FCM, at the instruction of and for the benefit of the clearinghouse. Any securities deposited to meet initial margin requirements are identified in the Schedule of Investments. Any cash deposited to meet initial margin requirements is presented in segregated cash with brokers for derivative instruments in the Statement of Assets and Liabilities. Centrally cleared swaps are marked-to-market daily and subsequent payments (variation margin) are made or received depending on the daily fluctuations in the value of the swaps and are recorded as unrealized appreciation or (depreciation). These daily payments, if any, are included in receivable or payable for daily variation margin on centrally cleared swaps in the Statement of Assets and Liabilities. Any premiums for centrally cleared swaps are recorded periodically throughout the term of the swap to variation margin and included in total accumulated earnings (loss) in the Statement of Assets and Liabilities. Any premiums are recognized as realized gain (loss) upon termination or maturity of the swap.
Payments are exchanged at specified intervals, accrued daily commencing with the effective date of the contract and recorded as realized gain or (loss). Some swaps may be terminated prior to the effective date and realize a gain or loss upon termination. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on swaps during the period is presented in the Statement of Operations.
Any open swaps at period end are included in the Schedule of Investments under the caption "Swaps", and are representative of volume of activity during the period, unless an average notional amount is presented in the table below.

Interest Rate Swaps. Interest rate swaps are agreements between counterparties to exchange cash flows, one based on a fixed rate, and the other on a floating rate. A fund enters into interest rate swaps to manage its exposure to interest rate changes. Changes in interest rates can have an effect on both the value of bond holdings as well as the amount of interest income earned. In general, the value of bonds can fall when interest rates rise and can rise when interest rates fall.
5. Purchases and Sales of Investments.
Purchases and sales of securities, other than short-term securities, U.S. government securities and in-kind transactions, as applicable, are noted in the table below.

6. Fees and Other Transactions with Affiliates.
Management Fee and Expense Contract. Fidelity Management & Research Company LLC (the investment adviser) and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee that is based on an annual rate of .20% of the Fund's average net assets. Under the management contract, the investment adviser pays all other expenses, except transfer agent fees, the compensation of the independent Trustees, and certain other expenses such as taxes.
In addition, under the expense contract, the investment adviser pays all other expenses as necessary, except the compensation of the independent Trustees, and certain other expenses such as taxes, so that total expenses do not exceed .35% of average net assets.
Transfer Agent Fees. Fidelity Investments Institutional Operations Company LLC (FIIOC), an affiliate of the investment adviser, is the Fund's transfer, dividend disbursing and shareholder servicing agent. FIIOC receives an asset-based fee of .10% of the Fund's average net assets. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements.
Interfund Trades. Funds may purchase from or sell securities to other Fidelity Funds under procedures adopted by the Board of Trustees. The procedures have been designed to ensure these interfund trades are executed in accordance with Rule 17a-7 of the 1940 Act. Any interfund trades are included within the respective purchases and sales amounts shown in the Purchases and Sales of Investments note. During the period, there were no interfund trades.
7. Committed Line of Credit.
Certain Funds participate with other funds managed by the investment adviser or an affiliate in a $4.25 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes.
Commitment fees are charged based on the unused amount of the line of credit at an annual rate of .10%, and then allocated to each participating fund based on its pro-rata portion of the line of credit. The commitment fees are borne by the investment adviser.
Interest is charged to a participating fund based on its borrowings at an annual rate of .75% plus the highest of (i) daily SOFR, (ii) Federal Funds Effective Rate, or (iii) Overnight Bank Funding Rate. During the period, there were no borrowings on this line of credit.
The line of credit agreement will expire in March 2027 unless extended or renewed.
8. Security Lending.
Funds lend portfolio securities from time to time in order to earn additional income. Lending agents are used, including National Financial Services (NFS), an affiliate of the investment adviser. Pursuant to a securities lending agreement, NFS will receive a fee, which is capped at 9.9% of a fund's daily lending revenue, for its services as lending agent. A fund may lend securities to certain qualified borrowers, including NFS. On the settlement date of the loan, the borrowers provide collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the fair value of the loaned securities during the period of the loan. The fair value of the loaned securities is determined at the close of business of a fund and any additional required collateral is delivered to a fund on the next business day. A fund or borrower may terminate the loan at any time, and if the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund may apply collateral received from the borrower against the obligation. A fund may experience delays and costs in recovering the securities loaned or gaining access to non-cash collateral. Any cash collateral received is invested in the Fidelity Securities Lending Cash Central Fund. Any loaned securities are identified as such in the Schedule of Investments, and the value of loaned securities and cash collateral at period end, as applicable, are presented in the Statement of Assets and Liabilities. For cash collateral, securities lending income represents the income earned on investing cash collateral less rebates paid to borrowers, plus any premium income received and is presented in the Statement of Operations as a component of income from Fidelity Central Funds. For non-cash collateral, securities lending income represents fees received from borrowers as compensation for the securities loaned and is presented in the Statement of Operations in security lending. Securities lending income is reduced by any lending agent fees associated with the loan. Affiliated security lending activity, if any, was as follows:
Total Security Lending Fees Paid to NFS ($)
Security Lending Income From Securities Loaned to NFS ($)
Value of Securities Loaned to NFS at Period End ($)

9. Expense Reductions.
Through arrangements with the Fund's custodian, credits realized as a result of certain uninvested cash balances were used to reduce the Fund's expenses by $322.
10. Other.
A fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the fund. In the normal course of business, a fund may also enter into contracts that provide general indemnifications. A fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against a fund. The risk of material loss from such claims is considered remote.
11. Risk and Uncertainties.
Many factors affect a fund's performance. Developments that disrupt global economies and financial markets, such as public health emergencies, military conflicts, terrorism, government restrictions, political changes, and environmental disasters, may significantly affect a fund's investment performance. The effects of these developments to a fund will be impacted by the types of securities in which a fund invests, the financial condition, industry, economic sector, and geographic location of an issuer, and a fund's level of investment in the securities of that issuer. Significant concentrations in security types, issuers, industries, sectors, and geographic locations may magnify the factors that affect a fund's performance.
