A. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Securities Valuation

Investments in securities traded on a national securities exchange, including exchange-traded futures and options, are valued at the last reported sales or settlement price on the day of valuation and are generally classified as level 1. Exchange-traded securities for which no sale was reported are valued at the most recent closing bid price from the exchange the security is primarily traded on and are generally classified as level 1. Equity certificates are valued at the last sale price of the underlying security as of the close of the primary exchange. Long-term U.S. fixed income securities are valued at the representative quoted bid price when held long or the representative quoted ask price if sold short or, if such prices are not available, at prices for securities of comparable maturity, quality and type or as determined by an independent pricing service. Long-term non-U.S. fixed income securities are valued at the mean of the representative quoted bid and ask prices when held long or sold short or, if such prices are not available, at prices for securities of comparable maturity, quality and type or as determined by an independent pricing service. The pricing service provider may employ methodologies that utilize actual market transactions, broker-dealer supplied valuations or other techniques. Such techniques generally consider factors such as composite security prices, yields, maturities, call features, credit ratings and developments relating to specific securities, in arriving at valuations. Fixed income securities are generally classified as level 2. The fair value analysis includes an analysis of the value of any unfunded commitments.

Short-term investments with remaining maturities of 60 days or less at the time of purchase are stated at amortized cost, which approximates fair value. If amortized cost does not approximate fair value, short-term securities are reported at fair value. These securities are generally classified as level 2. Swaps, forward foreign currency contracts and other financial derivatives are valued daily, primarily by an independent pricing service using pricing models and are generally classified as level 2. The pricing models use inputs that are observed from actively quoted markets such as issuer details, indices, spreads, interest rates, yield curves, dividends and exchange rates. If valuations are not available from the independent pricing service or values received are deemed not representative of fair value, values will be obtained from a third-party broker-dealer or counterparty. Investments initially valued in currencies other than the U.S. dollar are converted to the U.S. dollar using exchange rates obtained from an independent pricing service. In addition, for the Emerging Markets Growth Fund, Emerging Markets Small Cap Growth, Emerging Markets Opportunities Fund, and International Small Cap Growth Fund, if quotations are not readily available, if the values have been materially affected by events occurring after the closing of a foreign market, or if there has been a movement in the U.S. market that exceeds a certain threshold, assets may be valued at fair value as determined in good faith by or under the direction of the Trust’s Board of Trustees. Events that may materially affect asset values that could cause a fair value determination include, but are not limited to: corporate announcements relating to a specific security; natural and other disasters which may impact an entire market or region; and political and other events which may be global or impact a particular country or region. The frequency with which these procedures are used cannot be predicted and may be utilized to a significant extent. To the extent utilized, securities would be classified as level 2 in the hierarchy described below.

Securities for which market quotations are not readily available are valued at fair value as determined in good faith in accordance with procedures established by or under the direction of the Trust’s Board of Trustees and are generally classified as level 3. Under these procedures, the Funds primarily employ a market-based approach, which may use related or comparable assets or liabilities, recent transactions, market multiples, book values and other relevant information for the investment to determine the fair value of the investment. In addition, level 3 investments in certain early stage companies may be valued based upon initial transaction prices with management conducting ongoing assessments to determine whether new information is available to support a fair value adjustment. The information management may consider in its ongoing assessments may include, but are not limited to, actual or upcoming financing or third-party sale transactions, current or forecasted performance, or regulatory approval status updates. It is possible that estimated values may differ significantly from the values that would have been used had a ready market existed for the investments, and such differences could be material.

Each Fund is subject to fair value accounting standards that define fair value, establish the framework for measuring fair value and provide a three-level hierarchy for fair valuation based upon the inputs to the valuation as of the measurement date. The three levels of the fair value hierarchy are as follows:

Level 1 – quoted prices for active markets for identical securities

Driehaus Mutual Funds

Notes to Schedule of Investments (unaudited) — (Continued)

Level 2 – significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).

As of March 31, 2021, the Event Driven Fund held Level 3 investments in CM Life Sciences II, Inc. common stock, General Motors Corp. senior convertible preferred stock and Elevation Oncology, Inc. private preferred stock, valued in good faith in accordance with procedures established by or under the direction of the Trust’s Board of Trustees. The Level 3 shares of CM Life Sciences II, Inc. did not include warrants attached to the publicly traded stock. The share price of the CM Life Sciences II, Inc. shares were thus adjusted to reflect the removal of the value of such warrants. As a part of the ongoing restructuring of General Motors, any value previously ascribed to these holdings has been transferred to the General Motors Co. Motors Liquidation Co. GUC Trust common stock, which is freely and actively traded, and therefore the senior convertible preferred stock was fair valued at $0. The Elevation Oncology, Inc. private preferred stock was valued using a market approach as adjusted based on a recent round of financing for the Series B Preferred Shares of Elevation Oncology, Inc. The following table summarizes the quantitative inputs and assumptions used for items categorized as Level 3 of the fair value hierarchy as of March 31, 2021:

Financial Assets	Fair Value at March 31, 2021	Valuation Technique(s)	Unobservable Inputs	Price/Range
Convertible Preferred Stocks	$0	Cash available in relation to claim	Estimated recovery	—
Private Investment in Public Equity (PIPES)	$1,572,620	Market approach	Intrinsic value	$11.95
Private Preferred Stocks	$2,960,500	Market approach	Transaction price	$1.91

Securities Sold Short

The Event Driven Fund is engaged in selling securities short, which obligates it to replace a borrowed security by purchasing it at market price at the time of replacement. The Fund incurs a loss if the price of the security increases between the date of the short sale and the date on which the Fund replaces the borrowed security. The Fund realizes a gain if the price of the security declines between those dates. Gains are limited to the price at which the Fund sold the security short, while losses are potentially unlimited in size.

The Fund is required to establish a margin account with the broker lending the security sold short. While the short sale is outstanding, the broker retains the proceeds of the short sale and the Fund must maintain a deposit with the broker consisting of cash and securities having a value equal to a specified percentage of the value of the securities sold short.

Foreign Currency Spot Contracts

The Funds enter into foreign currency spot contracts to facilitate transactions in foreign currency denominated securities. These spot contracts are typically open for 2 to 5 days, depending on the settlement terms of the underlying security transaction. On March 31, 2021, the Funds had foreign currency spot contracts outstanding under which they are obligated to exchange currencies at specified future dates. The net unrealized appreciation or depreciation on spot contracts is reflected as receivable for investment securities sold or payable for investment securities purchased.

Foreign Currency Translation

The value of securities, currencies and other assets and liabilities not denominated in U.S. dollars are translated into U.S. dollar values based upon the current rates of exchange on the date of the Funds’ valuations.

Net realized foreign exchange gains or losses which are reported by the Funds result from currency gains and losses on transaction hedges arising from changes in exchange rates between the trade and settlement dates on forward contract transactions, and the difference between the amounts accrued for dividends, interest, and foreign taxes and the amounts actually received or paid in U.S. dollars for these items. Net unrealized foreign exchange gains and losses result from changes in the U.S. dollar value of assets and liabilities (other than investments in securities), which are denominated in foreign currencies, as a result of changes in exchange rates.

Driehaus Mutual Funds

Notes to Schedule of Investments (unaudited) — (Continued)

Net realized gain (loss) on foreign currency contracts on portfolio hedges result from the use of forward contracts to hedge portfolio positions denominated or quoted in a particular currency in order to reduce or limit exposure in that currency.

The Funds do not isolate that portion of the results of operations which results from fluctuations in foreign exchange rates on investments. These fluctuations are included with the net realized gain (loss) on investments and the net change in unrealized appreciation (depreciation) on investments.

Recent Accounting Pronouncements

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) “Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU 2020-04”), which provides optional temporary financial reporting relief from the effect of certain types of contract modifications due to the planned discontinuation of the London Interbank Offered Rate (“LIBOR”) and other interbank-offered based reference rates as of the end of 2021. The new guidance is effective for certain reference rate-related contract modifications that occur during the period March 12, 2020 through December 31, 2022, and the adoption of ASU 2020-04 is elective. Management is currently evaluating the impact, if any, of applying ASU 2020-04.

In October 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-08, "Codification Improvements to Subtopic 310-20, Receivables - Nonrefundable Fees and Other Costs". This ASU amends FASB ASU 2017-08, Premium Amortization on Purchased Callable Debt Securities, which provides guidance related to the amortization period for certain purchase callable debt securities held at a premium. ASU 2020-08 addresses premium amortization for callable debt securities with multiple call dates, clarifying that an entity should reevaluate whether a callable debt security purchased at a premium is in scope for each reporting period. ASU 2020-08 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, and should be applied on a prospective basis as of the beginning of the period of adoption for existing or newly purchased debt securities. At this time, management is still evaluating the implications of these changes on the financial statements.

Securities Transactions, Income and Commitments

The Trust records security transactions on trade date. Dividend income is recognized on the ex-dividend date, and interest income is recognized on an accrual basis. Premiums on securities are amortized over the period remaining until first call date, if any, or if none, the remaining life of the security and discounts are accreted over the remaining life of the security for financial reporting purposes. Withholding taxes on foreign dividends and interest have been provided for in accordance with the Trust’s understanding of the applicable country’s tax rules and rates.

Pursuant to the terms of certain of the senior unsecured loan agreements, certain Funds may have unfunded loan commitments, which are callable on demand. Each such Fund will have available with its custodian, cash and/or liquid securities having an aggregate value at least equal to the amount of the unfunded senior loan commitments. At March 31, 2021, the Funds had no unfunded senior loan commitments.

Certain Funds may invest in early-stage companies that may require additional contributions or funding if certain performance milestones are met. Management continuously assesses whether these companies will achieve these performance milestones and considers the impact of these commitments as they become due. Additionally, in connection with certain investments a Fund may provide commitments for future investments. At December 31, 2021, the Funds had no such outstanding commitments.

B. INVESTMENTS IN DERIVATIVES

Certain Funds use derivative instruments such as swaps, futures, options, swaptions, and forward foreign currency contracts in connection with their respective investment strategies. During the period January 1, 2021, through March 31, 2021, the Emerging Markets Opportunities Fund primarily utilized: 1) interest rate swaps to hedge against interest rate fluctuation and enable the parties involved to exchange fixed and floating cash flows; 2) credit default swaps as alternatives to direct investments to manage exposure to specific sectors/markets/industries and/or credit events and manage volatility; and 3) forward foreign currency contracts to manage currency risk in portfolio holdings. During the period January 1, 2021, through March 31, 2021, the Event Driven Fund primarily utilized: 1) options, including warrants, to both hedge exposure and provide exposure to certain market segments or specific securities; and 2) forward foreign currency contracts to manage currency risk in portfolio holdings. Detail regarding each derivative type is included below.

Swap Contracts

The Emerging Markets Opportunities Fund and Event Driven Fund engage in various swap transactions, including forward rate agreements and interest rate, currency, volatility, index, and total return swaps, primarily to manage duration and yield curve risk, or as alternatives to direct investments. Swaps that are centrally cleared are exposed to the creditworthiness of the clearing organizations (and, consequentially, that of their members generally, banks and broker-dealers) involved in the transaction. Centrally cleared swaps are valued daily and unrealized gains or losses are recorded in a variation margin account. The Fund receives from or pays to the clearing organization a specified amount of cash based upon changes in the variation margin account. When a contract is closed, the Fund recognizes a realized gain or loss.

Interest rate swaps are agreements between two parties to exchange cash flows based on a notional principal amount. A Fund may elect to pay a fixed rate and receive a floating rate or receive a fixed rate and pay a floating rate on a notional principal amount. The net interest received or paid on interest rate swap agreements is accrued daily as interest income/expense. Interest rate swaps are marked-to-market daily using fair value estimates provided by an independent pricing service. Changes in value, including accrued interest, are recorded as changes in net unrealized appreciation (depreciation). Unrealized appreciation is reported as an asset and unrealized depreciation is reported as a liability. Gains or losses are realized upon termination of the contracts. The risk of loss under a swap contract may exceed the amount recorded as an asset or a liability.

Total return swap contracts are arrangements to exchange a market or security linked return for a periodic payment, based on a notional principal amount, in order to hedge sector exposure and to manage exposure to specific sectors or industries and/or to gain exposure to specific markets/countries and to specific sectors/industries. To the extent that the total return of the security, index, or other financial measure underlying the transaction exceeds or falls short of the offsetting interest rate obligation, the Fund will receive a payment from or make a payment to the counterparty. Total return swap contracts are marked to market daily based upon quotations from market makers and the change, if any, is recorded as a change in net unrealized appreciation (depreciation). Unrealized appreciation is reported as an asset and unrealized depreciation is reported as a liability. Payments received or made are recorded as realized gains or losses. Gains or losses are realized upon termination of the contracts. Each Fund’s maximum risk of loss from counterparty risk is the fair value of the contract.

Volatility swaps are forward contracts on the future realized volatility of an underlying instrument. Volatility swaps are generally used to speculate on future volatility levels, trade the spread between realized and implied volatility or hedge volatility exposure of other positions. Changes in value are recorded as changes in net unrealized appreciation (depreciation). Unrealized gains are reported as an asset and unrealized losses are reported as a liability. Gains or losses are realized upon termination of the contracts. The risk of loss under a volatility swap contract is dependent upon the volatility of the underlying instrument.

Under the terms of a credit default swap, one party acts as a guarantor receiving a periodic payment that is a fixed percentage applied to a notional amount. In return, the party agrees to purchase the notional amount of the underlying instrument, at par, if a credit event occurs during the term of the contract. A Fund may enter into credit default swaps in which the Fund acts as guarantor (a seller of protection), and may enter into credit default swaps in which the counterparty acts as guarantor (a buyer of protection). Premiums paid to or by the Funds are accrued daily and included in net realized gain (loss) on swap contracts. The contracts are marked-to-market daily using fair value estimates provided by an independent pricing service. Changes in value are recorded as unrealized appreciation (depreciation). Unrealized gains are reported as an asset and unrealized losses are reported as a liability. Gains or losses are realized upon termination of the contracts. The risk of loss under a swap contract may exceed the amount recorded as an asset or a liability. The notional amount of a swap contract is the reference amount pursuant to which the counterparties make payments. For swaps in which the referenced obligation is an index, in the event of default of any debt security included in the corresponding index, the Fund pays or receives the percentage of the corresponding index that the defaulted security comprises (1) multiplied by the notional value and (2) multiplied by the ratio of one minus the ratio of the market value of the defaulted debt security to its par value.

Risks associated with swap contracts include changes in the returns of underlying instruments and/or interest rates, failure of the counterparties to perform under the contracts’ terms and the possible lack of liquidity with respect to the contracts. For centrally cleared swap contracts, counterparty risk is limited due to the role of the clearinghouse. Credit default swaps can involve greater risks than if an investor had invested in the reference obligation directly since, in

addition to general market risks, credit default swaps are subject to counterparty credit risk, leverage risk, hedging risk, correlation risk, and liquidity risk. The Funds disclose swap contracts on a gross basis, with no netting of contracts held with the same counterparty.

Options Contracts

The Funds may use options contracts, which include warrants, to hedge downside risk, produce incremental earnings or protect against market changes in the value of equities or interest rates. The Funds may write covered call and put options on futures, swaps, securities, or currencies the Funds own or in which they may invest. Writing put options tends to increase a Fund’s exposure to the underlying instrument. Writing call options tends to decrease a Fund’s exposure to the underlying instrument. When a Fund writes a call or put option, an amount equal to the premium received is recorded as a liability and subsequently marked to market to reflect the current value of the option written. These liabilities are reflected as written options outstanding in the Schedule of Investments. Premiums received from writing options that expire are treated as realized gains. Premiums received from writing options that are exercised or closed are added to the proceeds or offset against amounts paid on the underlying future, swap, security or currency transaction to determine the realized gain or loss. A Fund, as a writer of an option, has no control over whether the underlying future, swap, security, or currency may be sold (call) or purchased (put) and, as a result, bears the market risk of an unfavorable change in the price of the future, swap, security, or currency underlying the written option. The risk exists that a Fund may not be able to enter into a closing transaction because of an illiquid market. In addition, to the extent a Fund purchases an over-the-counter (“OTC”) option, it is subject to credit risk that the counterparty to the trade does not perform under the contract’s terms. The Funds are not subject to credit risk on OTC options written as the counterparty has already performed its obligation by paying the premium at the inception of the contract.

The Funds may also purchase put and call options. Purchasing call options tends to increase a Fund’s exposure to the underlying instrument. Purchasing put options tends to decrease a Fund’s exposure to the underlying instrument. A Fund pays a premium, which is included in its Schedule of Investments as an investment and subsequently marked-to-market to reflect the current value of the option. Premiums paid for purchasing options that expire are treated as realized losses. The risk associated with purchasing put and call options is limited to the premium paid. Premiums paid for purchasing options that are exercised or closed are added to the amounts paid or offset against the proceeds on the underlying future, swap, security or currency transaction to determine the realized gain or loss. When entering into purchased option contracts, a Fund bears the risk of securities prices moving unexpectedly, in which case, a Fund may not achieve the anticipated benefits of the purchased option contracts; however, the risk of loss is limited to the premium paid.

Forward Foreign Currency Contracts

Certain Funds use forward foreign currency contracts to manage foreign currency, to produce incremental earnings or to hedge existing positions. A forward foreign currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. These contracts are principally traded in the inter-bank market conducted directly between currency traders (usually large commercial banks) and their customers.

The market value of a forward foreign currency contract fluctuates with changes in currency exchange rates. Outstanding forward foreign currency contracts are valued daily at current market rates and the resulting change in market value is recorded as change in net unrealized appreciation or depreciation. When a forward foreign currency contract is settled, the Fund records a realized gain or loss equal to the difference between the value at the time the forward foreign currency contract was opened and the value at the time it was settled. A forward foreign currency contract may involve market risk in excess of the unrealized appreciation (depreciation). In addition, the Funds could be exposed to credit risk if the counterparties are unable or unwilling to meet the terms of the contracts or market risk if the value of the foreign currency changes unfavorably.

Equity Certificates

Certain Funds may invest in equity certificates, which allow the Funds to participate in the appreciation (depreciation) of the underlying security without actually owning the underlying security. These instruments are purchased pursuant to an agreement with a financial institution and are valued at a calculated market price based on the value of the underlying security in accordance with the agreement. These equity certificates are subject to the credit risk

of the issuing financial institution. There is no off-balance sheet risk associated with equity certificates and the Funds’ potential loss is limited to the purchase price of the securities. The Funds are exposed to credit risk associated with the counterparty to the transaction, which is monitored by the Funds’ management on a periodic basis. A Fund’s equity certificates are not subject to any master netting agreement.

C. FOREIGN INVESTMENT RISKS

To the extent a Fund invests in foreign securities, it may entail risks due to the potential for political and economic instability in the countries where the issuers of these securities are located. In addition, foreign exchange fluctuations could affect the value of positions held. These risks are generally intensified in emerging markets.

D. SUBSEQUENT EVENTS

Events or transactions that occurred after the date of this report through the date the report was issued have been evaluated for potential impact to the financial statements. Other than as presented below, there are no subsequent events that require recognition or disclosure in the financial statements.

As was previously disclosed in the Funds’ registration statement, an interim advisory agreement (“Interim Advisory Agreement”) had been put in place with the Funds’ investment adviser (the “Adviser”) on March 9, 2021 (the “Effective Date”) following a technical change in control which was caused by the death of the Adviser’s Chairman and controlling owner. Unless the Interim Advisory Agreement is permissibly extended, it will terminate upon the earlier of: (a) 150 calendar days after the Effective Date (that is, August 6, 2021); or (b) the approval of a new investment advisory agreement by the shareholders of the Funds. On April 29, 2021, the Board of Trustees of the Driehaus Mutual Funds unanimously approved a new advisory agreement (the “New Agreement”) and approved its submission to shareholders for their vote for or against the proposal.
