Fund Fees and Expenses
This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and examples below. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $25,000 in Class A Shares of the Alger Family of Funds, including the Fund. More information about these and other discounts is available from your financial professional and in “Purchasing and Redeeming Fund Shares” on page 12 and in Appendix A – Waivers and Discounts Available from Intermediaries on page A-1 in the Fund’s Prospectus, and in the sections “Right of Accumulation (Class A Shares)” and “Letter of Intent (Class A)” on page 27 of the Fund’s Statement of Additional Information.

The following examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The examples assume that you invest $10,000 in the Fund for the time periods indicated, that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Portfolio Turnover
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 107.82% of the average value of its portfolio.

Prospectus 2/25

Principal Investment Strategy
Fred Alger Management, LLC (the “Manager”) believes companies undergoing Positive Dynamic Change offer the best investment opportunities. Positive Dynamic Change refers to companies realizing High Unit Volume Growth or companies undergoing Positive Lifecycle Change. High Unit Volume Growth companies are traditional growth companies experiencing, for example, rapidly growing demand or market dominance. Positive Lifecycle Change companies are, for example, companies benefitting from new regulations, a new product innovation or new management.
Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies of any market capitalization that the Manager believes demonstrate promising growth potential. Equity securities include common or preferred stocks that are listed on U.S. or foreign exchanges.
As a focus fund, the Fund intends to invest a substantial portion of its assets in a smaller number of issuers. Generally the Fund will own approximately 50 holdings. Fund holdings may occasionally differ from this number for a variety of reasons, including, among others, because of extreme market volatility, such as when the Fund has entered a temporary defensive position. Additionally, the Fund may temporarily exceed the stated number of holdings when it acquires a new holding and determines that it is in the best interests of shareholders to sell an existing holding over a period of time, instead of immediately selling the entire holding.
The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including the information technology, consumer discretionary, communication services, and healthcare sectors.
The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive. As a result, the Fund may engage in active trading of portfolio securities.
The Fund can invest in foreign securities.
Principal Risks
An investment in the Fund involves risks. The Fund’s share price may go down, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following is a summary description of principal risks involved in investing in the Fund.
Investment Risk – An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest.
Market Risk – Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, recessions, or other events could have a significant impact on the Fund and its investments.
Equity Securities Risk – As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund’s price per share will fluctuate due to changes in the market prices of its investments. Also, the Fund’s investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds.
Growth Stocks Risk – Prices of growth stocks tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value.
Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility.
Technology Companies Risk – The Fund may have a significant portion of its assets invested in securities of technology-related companies. Therefore, the Fund may be more susceptible to particular risks that may affect companies in the information technology sector and technology-related sectors than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole. Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a

Prospectus 3/25

result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of technology related companies’ securities may fall or fail to rise. Many technology related companies’ securities have historically been more volatile than other securities, especially over the short term.
Consumer Discretionary Sector Risk – The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns.
Healthcare Companies Risk – The Fund may have a significant portion of its assets invested in securities of healthcare companies. At times, the performance of healthcare companies will lag the performance of other industries or the broader market as a whole, and the performance of such companies may be more volatile. Healthcare companies may also be significantly affected by intense competition, aggressive pricing, government regulation, technological innovations, product obsolescence, patent considerations, product compatibility and consumer preferences.
Communications Services Sector Risk – Communication services companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.
Small Number of Holdings Risk – Under normal circumstances, the Fund invests in a small number of issuers. Therefore, the Fund’s performance may be more vulnerable to changes in the market value of a single issuer and more susceptible to risks associated with a single economic, political, or regulatory occurrence than a fund that has a higher number of holdings.
Foreign Securities Risk – The Fund’s performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing audit, regulatory, and legal standards and lack of financial reporting standards.
Portfolio Turnover (Active Trading) Risk – Because the Fund may engage in active trading of portfolio securities, it may incur increased transaction costs and brokerage commissions, both of which can lower the actual return on an investment. Active trading may also increase short-term gains and losses, which may affect the taxes a shareholder has to pay.
Performance
The following bar chart and the table beneath it provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for the indicated periods compare with those of an appropriate benchmark of market performance. Performance in the bar chart does not reflect the effect of the sales charge imposed on purchases of Class A Shares of the Fund. If the bar chart reflected the applicable sales charges, returns would be less than those shown. On October 15, 2018, Alger Capital Appreciation Focus Fund changed its name to Alger Focus Equity Fund. The Fund’s past performance (before and after taxes) is not necessarily an indication of how it will perform in the future.

Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. The after-tax returns shown may not be relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns for Class C Shares, which are not shown, will vary from those shown for Class A Shares. A “Return After Taxes on Distributions and Sale of Fund Shares” may sometimes be higher than the other two return figures; this happens when there is a capital loss on redemptions, giving rise to a tax benefit to the shareholder.

Investment Objective, Principal Investment Strategies and Related Risks
The investment objective, principal strategy and primary risks of the Fund are discussed in the Fund’s Summary Section in this Prospectus. The Fund has adopted a policy to invest at least 80% of its assets in specified securities appropriate to its name (as described in the Fund’s Summary Section in this Prospectus) and to provide shareholders with at least 60 days’ prior notice of any change with respect to this policy. The Fund’s investment objective is a fundamental investment policy and may not be changed without shareholder approval. The Fund may, from time to time, take temporary defensive positions that are inconsistent with the Fund’s principal investment strategies in attempting to respond to adverse market, economic, political, or other conditions. The Fund may not achieve its investment objective while in a temporary defensive position.
All of the Fund’s share classes invest in the same portfolio of securities. Performance of each share class will vary from the performance of the Fund’s other share classes due to the differences in charges or expenses. The Fund’s past performance (before and after taxes) is not necessarily an indication of how it will perform in the future.
The index used in the Summary Section is a broad-based index designed to track a particular market or market segment. No expenses, fees or taxes are reflected in the returns for the index, which is unmanaged. All returns for the index assume reinvestment of dividends and interest of the underlying securities that make up the index. Investors cannot invest directly in the index.
Russell 1000 Growth Index: An unmanaged index designed to measure the performance of a subset of the largest 1,000 capitalization companies in the Russell 3000 Index with higher price-to-book ratios and higher forecasted growth values.
Additional Information About the Fund’s Investment Strategies and Investments
Investment Objective
Alger Focus Equity Fund seeks long-term capital appreciation.
Principal Investment Strategies
The following are the Fund’s investment process and principal investment strategies. The Fund may invest in other securities that are not its principal strategy, and such strategies and related risks are described in more detail in the Fund’s Statement of Additional Information (“SAI”).
The Fund invests primarily in equity securities. The Fund’s investments in equity securities are primarily in common or preferred stocks, but its equity investments may also include securities convertible into or exchangeable for equity securities (including warrants and rights) and depositary receipts. The Fund invests primarily in companies whose securities are traded on U.S. or foreign exchanges.
The Fund invests primarily in “growth” stocks. The Fund’s investment manager, Fred Alger Management, LLC (“Alger Management” or the “Manager”), believes that these companies tend to fall into one of two categories:
High Unit Volume Growth
Vital, creative companies that offer goods or services to a rapidly expanding marketplace. They include both established and emerging firms, exercising market dominance, offering new or improved products, or simply fulfilling an increased demand for an existing product line.
Positive Life Cycle Change
Companies experiencing a major change which is expected to produce advantageous results. These changes may be as varied as new management, products or technologies; restructuring or reorganization; regulatory change; or merger and acquisition.
ESG Integration
Although the Fund does not seek to implement a specific environmental, social and governance (“ESG”), impact or sustainability strategy unless otherwise disclosed, the Manager has sought to ESG considerations into its investment process through the use of both third-party ESG specific information and its own proprietary research. Specifically, with respect to 75% of its assets under management, the Manager evaluates a company’s ESG factors and, based on such factors, may engage with the company to (i) identify drivers of poor ESG metrics; (ii) interview management with key questions about ESG issues; and (iii) evaluate the prospect of positive ESG change within a company. Upon conclusion of this engagement, a report is published to the Manager’s research database to ensure that all portfolio managers have access to the report summarizing the company’s ESG issues, the results of any meeting/interview with the company, an ESG rating of the company and any other relevant factors. The author of each report will meet with portfolio managers as necessary to discuss the ESG report and the impact the report may have on the overall investment view of the company.

Prospectus 7/25

The Manager may change the sources for such ESG information, including by adding or modifying the information it receives from third-party firms, selecting different third-party firms, using company provided information, or performing different or additional internal assessments. To assist with efforts to incorporate ESG considerations into the investment process, all of the Manager’s investment professionals have access to company-specific ESG reports. The Manager has established an ESG steering committee comprised of executive management and senior investment professionals to oversee this process.
ESG characteristics are not the sole considerations when making investment decisions for the Fund. Further, investors can differ in their views of what constitutes positive or negative ESG characteristics. As a result, the Fund may invest in issuers that do not reflect the beliefs and values with respect to ESG of any particular investor. ESG considerations may affect the Fund’s exposure to certain companies or industries and the Fund may forego certain investment opportunities. While the Manager views ESG considerations as having the potential to contribute to the Fund’s long-term performance, there is no guarantee that such results will be achieved.
Principal Risks
This section contains a discussion of the general risks of investing in the Fund. The “Investment Strategies and Policies” section in the SAI also includes more information about the Fund and its investments and the related risks. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or by any bank or governmental agency. As with any fund, an investment in the Fund involves risks.
Investment Risk
An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest.
Market Risk
Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, recessions, or other events could have a significant impact on the Fund and its investments.
Equity Securities Risk
As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund’s price per share will fluctuate due to changes in the market prices of its investments. Because stock markets tend to move in cycles, stock prices overall may decline. A particular stock’s market value may decline as a result of general market conditions that are not related to the issuing company (e.g., adverse economic conditions or investor sentiment) or due to factors that affect the particular company (e.g., management performance or factors affecting the industry). Also, the Fund’s investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds.
Growth Stocks Risk
Prices of growth stocks tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value. Expected growth may not be realized.
Sector Risk
The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility.
Technology Companies Risk – The Fund may be more susceptible to particular risks that may affect companies in the information technology sector and technology-related sectors than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole. Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological

Prospectus 8/25

developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of technology related companies’ securities may fall or fail to rise. Many technology related companies’ securities have historically been more volatile than other securities, especially over the short term.
Consumer Discretionary Sector Risk – The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.
Healthcare Companies Risk – The Fund may be more susceptible to particular risks that may affect companies in the healthcare sector than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole, and the performance of such companies may be more volatile. The healthcare field is subject to substantial governmental regulation and may, therefore, be adversely affected by changes in governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of healthcare companies’ securities may fall or fail to rise. In addition, companies in the healthcare sector can be significantly affected by intense competition, aggressive pricing, technological innovations, product obsolescence, patent considerations, product compatibility and consumer preferences.
Communications Services Sector Risk – Communication services companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.
Small Number of Holdings Risk
The Fund’s performance may be more vulnerable to changes in the market value of a single issuer and more susceptible to risks associated with a single economic, political, or regulatory occurrence than a fund that has a higher number of holdings. At times, the performance of shares of particular companies will lag the performance of other sectors or the market as a whole. This risk is magnified when a fund has a small number of holdings. Generally, the more broadly a fund invests, the more it spreads its risks and potentially reduces the risk of loss and volatility.
Foreign Securities Risk
Investing in foreign securities involves risks related to the political, social and economic conditions of foreign countries, particularly emerging market countries. These risks may include political instability, exchange control regulations, expropriation, lack of comprehensive information, national policies restricting foreign investment, currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing auditing, regulatory and legal standards and lack of accounting and financial reporting standards, inflation and rapid fluctuations in inflation, withholding or other taxes, and operational risks. There may be less stringent government supervision and oversight of foreign markets than in the United States. There may be less corporate financial information publicly available, less stringent investor protection and disclosure standards, and differing auditing and legal standards.
Investment in foreign currencies is subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedged positions, that the U.S. dollar will decline relative to the currency being hedged. Currency rates in foreign countries may fluctuate significantly over short periods of time. A decline in the value of foreign currencies relative to the U.S. dollar will reduce the value of securities held by the Fund and denominated in those currencies. Foreign currencies also are subject to risks caused by inflation, interest rates, budget deficits and low savings rates, political factors and government controls.
Portfolio Turnover (Active Trading) Risk
Because the Fund may engage in active trading of portfolio securities, it may incur increased transaction costs and brokerage commissions, both of which can lower the actual return on an investment. Active trading may also increase short-term gains and losses, which may affect the taxes a shareholder has to pay.

Prospectus 9/25

Temporary Defensive Investments
In times of adverse or unstable market, economic or political conditions, the Fund may invest up to 100% of its assets in cash, high-grade bonds, or cash equivalents (such as commercial paper or money market instruments) for temporary defensive reasons. This is to attempt to protect the Fund’s assets from a temporary, unacceptable risk of loss, rather than directly to promote the Fund’s investment objective. The Fund may also hold these types of securities in an amount up to 15% of net assets, pending the investment of proceeds from the sale of Fund shares or portfolio securities or to meet anticipated redemptions of Fund shares. The Fund may not achieve its investment objective while in a temporary defensive position.

Net Asset Value
The value of one share is its net asset value, or “NAV.” The Fund values its financial instruments at fair value using independent dealers or pricing services under policies approved by the Board. Investments held by the Fund are valued on each day the New York Stock Exchange (the “NYSE”) is open, as of the close of the NYSE (normally 4:00 p.m. Eastern Time).
NAV of a class of shares is computed by adding together the value allocable to the class of the Fund’s investments plus cash and other assets, subtracting applicable liabilities and then dividing the result by the number of outstanding shares of the class.
Investments in money market funds and short-term securities held by the Fund having a remaining maturity of sixty days or less are valued at amortized cost which approximates market value.
Equity securities, including traded rights, warrants and option contracts for which valuation information is readily available, are valued at the last quoted sales price or official closing price on the primary market or exchange on which they are traded as reported by an independent pricing service. In the absence of quoted sales, such securities are valued at the bid price or, in the absence of a recent bid price, the equivalent as obtained from one or more of the major market makers for the securities to be valued.
Foreign securities are usually valued on the basis of the most recent closing price of the foreign markets on which such securities principally trade. Securities in which the Fund may invest may be traded in foreign markets that close before the close of the NYSE. Developments that occur between the close of the foreign markets and the close of the NYSE may result in adjustments to the closing foreign prices to reflect what the Manager, pursuant to policies established by the Board, believes to be the fair value of these securities as of the close of the NYSE. The Fund may also fair value securities in other situations, for example, when a particular foreign market is closed but the Fund is open.
Securities for which market quotations are not readily available are valued at fair value, as determined in good faith pursuant to procedures established by the Board.
The Fund’s valuation techniques are generally consistent with either the market or the income approach to fair value. The market approach considers prices and other relevant information generated by market transactions involving identical or comparable assets to measure fair value. The income approach converts future amounts to a current, or discounted, single amount. These fair value measurements are determined on the basis of the value indicated by current market expectations about such future events. Because of the inherent uncertainty and often limited markets for restricted securities, the valuations assigned to such securities by the Fund may significantly differ from the valuations that would have been assigned by the Fund had there been an active market for such securities.
Valuation processes are determined by a valuation committee (the “Valuation Committee”) authorized by the Board and comprised of representatives of the Manager and officers of the Trust. The Valuation Committee reports its fair valuation determinations and related valuation information to the Board. The Board is responsible for approving the valuation policy and procedures. While the meetings are held on an as-needed basis, the Valuation Committee generally meets quarterly to review and evaluate the effectiveness of the procedures for making fair value determinations. The Valuation Committee considers, among other things, the results of quarterly back testing of the fair value model for foreign securities, pricing comparisons between primary and secondary price sources, the outcome of price challenges put to the Fund’s pricing vendor, and variances between transactional prices and the previous day’s price.

Purchasing and Redeeming Fund Shares
Shares of the Fund can be purchased or redeemed on any day the NYSE is open. Orders will be processed at the NAV next calculated after the purchase or redemption request is received in good order by the Transfer Agent or other agent appointed by the Distributor. Ordinarily, the Fund will issue a redemption check within seven days after the Transfer Agent receives a redemption request in good order. “In good order” means that all necessary information and documentation related to the redemption request have been provided to the Transfer Agent or authorized intermediary, if applicable. If your request is not in good order, the Transfer Agent may require additional documentation in order to redeem your shares. However, when you buy shares with a check, via Automatic Investment Plan, or online, the Fund will not issue payment for redemption requests against those funds until the purchase proceeds are available, which may take up to 15 days. Payment may be postponed in cases where the SEC declares an emergency or normal trading is halted. The Transfer Agent or the Fund may reject any purchase order. Share certificates are not issued for shares of the Fund.
Under normal circumstances, the Fund expects to meet redemption requests by using cash or cash equivalents in its portfolio and/or by selling portfolio assets to generate cash. The Fund also may pay redemption proceeds using cash obtained through borrowing arrangements that may be available from time to time.
The Fund may pay all or a portion of your redemption proceeds in securities rather than cash (i.e., “redeem in kind”) if, for example, the redemption request is during stressed market conditions or the Fund believes that a cash redemption may have a substantial impact on the Fund and its remaining shareholders. Securities will generally be selected on a pro rata basis pursuant to the Fund’s procedures. A shareholder who receives a redemption in kind bears the market risk of the securities until they are converted into cash, in transactions conducted at the shareholder’s expense.
Legislation passed by Congress in 2008 requires mutual funds to report both to the shareholder and to the Internal Revenue Service the “cost basis” of shares acquired on or after January 1, 2012 that are subsequently redeemed or exchanged. This reporting is not required for Fund shares held in retirement or other tax-advantaged accounts or for certain other types of entities (such as C corporations).
If you are a direct shareholder, you may request your cost basis reported on Form 1099-B to be calculated using any one of the alternative methods offered by the Fund. Please contact the Fund to make, revoke, or change your election. If you do not affirmatively elect a cost basis method then the Fund will use the average cost basis method. If you hold Fund shares through a broker, please contact that broker with respect to the reporting of cost basis and available elections for your account.
Please note that you will continue to be responsible for calculating and reporting gains and losses on redemptions of shares purchased prior to January 1, 2012. You are encouraged to consult your tax advisor regarding the application of the cost basis reporting rules and, in particular, which cost basis calculation method is best for you.
Dividends and Distributions and Tax Consequences
The Fund declares and pays dividends and distributions annually, and expect these payments to shareholders will consist primarily of capital gains, which may be taxable to you at different rates depending upon how long the Fund held the securities that it sold to create the gains (rather than the length of time you have held shares of the Fund), and that they will also include net investment income, which is taxable as ordinary income. Certain dividend income received by the Fund and paid to you may be subject to a maximum tax rate of 20% (qualified dividends); other income paid to you, such as non-qualifying dividend income or interest earned on debt securities held by the Fund, will continue to be taxed at the higher ordinary income rates. Dividends and distributions may differ among classes of shares of the Fund. Unless your investment is in a tax-deferred account, you may want to avoid buying shares shortly before the Fund pays a dividend. If you buy shares when the Fund has declared, but not yet distributed ordinary income or capital gains, you will pay full price for the shares and then receive a portion of the price back in the form of a taxable dividend. In addition, it may be the case that a significant amount of the securities held by the Fund are held at values above their purchase price. In such cases, the sale of such securities in the Fund, which may be from a portfolio management decision or to meet Fund shareholder redemptions, will generate either long-term or short-term capital gains, which will be distributed and taxable to you as described above if your investment is not in a tax-deferred account. Therefore, a substantial tax liability may arise for a shareholder who invests in the Fund when such conditions exist. The amount of long-term and short-term capital gains are disclosed in the Fund’s most recent annual or semi-annual report. Before investing you may want to consult your tax advisor.
Unless you choose to receive cash payments by checking the box on your account application, any dividends and distributions will be reinvested automatically at the NAV on their payment dates. No additional sales charge will apply to automatically reinvested dividends and distributions. If you have chosen cash payments and a payment is returned to the Fund as undeliverable, that payment will be reinvested upon receipt by the Transfer Agent in Fund shares at the next NAV. All subsequent payments will be reinvested until you reinstate your cash election and provide a valid mailing address.
Regardless of whether you choose to take distributions in cash or reinvest them in the Fund, they may be subject to federal and state taxes. An exchange of Fund shares for shares of another fund will be treated as a sale of the Fund shares, and any gain on the

Prospectus 13/25

transaction may be subject to federal and state taxes. Because everyone’s tax situation is unique, see a tax advisor about federal, state and local tax consequences of investing in the Fund.
Classes of Fund Shares
Alger Focus Equity Fund offers five classes of shares (A, C, I, Y, and Z Shares). Each of Alger Mid Cap Growth Institutional Fund and Alger Small Cap Growth Institutional Fund offers three classes of shares (Class I, R and Z-2 Shares).

date. It is a financial intermediary’s responsibility to
ensure that the shareholder is credited with the proper
holding period. Certain financial intermediaries who
hold Class C shares in an omnibus account for
shareholders of group retirement plans may not track
participant level aging of shares and therefore these
shares may not be eligible for an automatic conversion.
Shareholders who purchased Class C shares through
certain financial intermediaries or group retirement plan
recordkeeping platforms or whose shares are held in
an omnibus account may not be eligible to participate
in such Class C share conversions.
Investors with non-U.S. addresses and intermediary controlled accounts designated as foreign accounts (“Restricted Accounts”) are restricted from investing in the Fund. Existing Restricted Accounts may remain in the Fund, but are prohibited from making

further investments. U.S. Armed Forces and Diplomatic post office addresses abroad are treated as U.S. addresses and can invest in the Fund. Addresses in U.S. territories, such as Guam and Puerto Rico, are also treated as U.S. addresses and can invest in the Fund.
Sales Charges
The availability of certain sales charge waivers and reductions will depend on whether you purchase your shares directly from the Fund or through a financial intermediary. Financial intermediaries may have different policies and procedures regarding the availability of front-end sales charge waivers or deferred sales charge waivers, which are discussed below. In all instances, it is your responsibility to notify the Fund or your financial intermediary at the time of purchase of any relationship or other facts qualifying you for sales charge waivers or reductions. For waivers and discounts not available through a particular financial intermediary, shareholders will have to purchase Fund shares directly from the Fund or through another financial intermediary to receive these waivers or reductions. Please see “Appendix A – Waivers and Discounts Available from Intermediaries” at the end of this Prospectus.

Purchases of Class A Shares which, when combined with current holdings of Class A Shares of the Alger Family of Funds offered with a sales charge, equal or exceed $1,000,000 in the aggregate may be made at net asset value without any initial sales charge, but may be subject to a contingent deferred sales charge (“CDSC”) of 1.00% on redemptions made within 12 months of purchase. The CDSC is waived if the shareholder’s financial intermediary notified the Distributor before the shareholder purchased the Class A Shares that the financial intermediary would waive the 1.00% Dealer Allowance noted in the chart above.
In calculating a CDSC, the Fund assumes first, that the redemption is of shares, if any, that are not subject to any CDSC.
Distribution and/or Service (12b-1) Fees
The Fund has adopted a plan pursuant to Rule 12b-1 under the 1940 Act that allows Class A Shares to pay a 0.25% fee out of its assets on an ongoing basis for distribution and shareholder services provided to Class A shareholders. The Distributor may pay some or all of this fee to a broker-dealer, investment adviser or other financial institution (“Financial Intermediary”) that also provides distribution, servicing and/or maintenance of shareholder accounts. These fees will increase the cost of your investment in Class A Shares and may cost you more than paying other types of sales charges.

Class C Shares
Class C Shares are only offered to investors through certain Financial Intermediaries and group retirement plan recordkeeping platforms. See “Investment Instructions – Special Instructions for Class C Shares.”
There is no sales charge when you buy Class C Shares. When you redeem Class C Shares, you may pay the following CDSC:

In calculating a CDSC, the Fund assumes, first, that the redemption is of shares, if any, that are not subject to any CDSC. The Fund’s Distributor collects and retains any applicable CDSC paid. Under certain circumstances, the CDSC may be waived. These circumstances are discussed below and in the SAI.
Class C Share Conversion Feature
On the fifth business day of the month following the eighth anniversary of the purchase date of a shareholder’s Class C Shares, such Class C Shares will automatically convert to Class A Shares without the imposition of any sales load, fee or other charge. At conversion, a proportionate amount of shares representing reinvested dividends and distributions will also be converted into Class A Shares.
Shareholders who purchase Class C Shares through certain Financial Intermediaries or group retirement plan recordkeeping platforms or whose shares are held in an omnibus account may not be eligible to participate in such Class C Share conversion. Certain financial intermediaries who hold Class C Shares in an omnibus account for shareholders of group retirement plans may not track participant level aging of shares and therefore those shares also may not be eligible for an automatic conversion. Contact your Financial Intermediary or plan recordkeeper for eligibility information. See Appendix A – Waivers and Discounts Available from Intermediaries in this prospectus for further details regarding Class C Share conversion schedules available from certain intermediaries.
Distribution and/or Service (12b-1) Fees
The Fund has adopted a plan pursuant to Rule 12b-1 under the 1940 Act that allows Class C Shares to pay a 1.00% fee (0.75% distribution and/or shareholder services and 0.25% shareholder services) out of its assets on an ongoing basis for distribution and shareholder services provided to Class C shareholders. The Distributor may pay some or all of this fee to a Financial Intermediary that also provides servicing and/or maintenance of shareholder accounts. These fees will increase the cost of your investment in Class C Shares and may cost you more than paying other types of sales charges. At the time of the initial sale of Class C Shares, the Distributor generally pays a Financial Intermediary from its own resources an upfront commission of 1% of the amount invested. This amount represents a prepayment of the first year’s distribution and shareholder servicing fees. In the first year following the initial sale, the Fund pays the distribution and shareholder service fees to the Distributor as reimbursement for the Distributor’s upfront commission. If you redeem your Class C Shares on or before the first anniversary date of your purchase of your Class C Shares, you will pay a 1% CDSC. In the first year, the payment of a CDSC may result in the Distributor receiving amounts greater than the upfront commission paid to the Financial Intermediary. For Class C Shares held over a year, the Fund pays the distribution and shareholder service fees to the Distributor, who is responsible for paying Financial Intermediaries.
Maximum Investment Amount
The maximum investment limit for Class C Shares is $999,999.

Waivers of Sales Charges
Different financial intermediaries may impose different sales charges or offer different sales charge discounts. These variations are described at the end of this Prospectus in Appendix A – Waivers and Discounts Available from Intermediaries.
No initial sales charge is imposed on purchases of Class A Shares, and no CDSC is imposed on redemptions of Class A and C Shares by:
employees, officers and/or Trustees of the Distributor and its affiliates,
Individual Retirement Accounts (“IRAs”), Keogh Plans and employee benefit plans for those persons, and
spouses, children, siblings and parents of those employees and trusts of which those individuals are beneficiaries, as long as orders for the shares on behalf of those individuals and trusts were placed by those persons;
accounts managed by the Manager,
employees, participants and beneficiaries of those accounts,
IRAs, Keogh Plans and employee benefit plans for those employees, participants and beneficiaries, and
spouses and minor children of those employees, participants and beneficiaries as long as orders for the shares were placed by the employees, participants and beneficiaries;
employee benefit or retirement plans or charitable accounts, including, but not limited to, IRAs, Keogh Plans, 401(k) plans, profit-sharing pension plans, defined benefit plans, Taft-Hartley multiemployer pension plans, 457 plans, 403(b) plans, non-qualified deferred compensation plans, and other defined contribution plans subject to the Employee Retirement Income Security Act of 1974, as amended, other than employee benefit or retirement plans or charitable accounts that purchase Class A Shares through brokerage relationships in which sales charges are customarily imposed;
an investment company registered under the 1940 Act, as amended, in connection with the combination of the investment company with the Fund by merger, acquisition of assets or by any other transaction;
registered investment advisers for their own accounts;
certain registered investment advisers, banks, trust companies and other financial institutions (including broker-dealers) that have an agreement in place with the Distributor (see Appendix A – Waivers and Discounts Available from Intermediaries of this Prospectus for a list of such entities), as long as the orders for the shares were placed on behalf of their clients;
certain financial intermediaries offering self-directed investment brokerage accounts that have an agreement in place with the Distributor (see Appendix A – Waivers and Discounts Available from Intermediaries of this Prospectus for a list of such entities);
a financial institution as shareholder of record on behalf of:
investment advisers or financial planners trading for their own accounts or the accounts of their clients, and who charge a separate fee for their services, and
clients of such investment advisers or financial planners trading for their own accounts if the accounts are linked to the master account of such investment adviser or financial planner on the books and records of the financial institution;
a financial institution as shareholder of record on behalf of retirement and deferred compensation plans and trusts used to fund those plans;

Prospectus 17/25

registered representatives of broker-dealers that have an agreement in place with the Distributor, for their own accounts and their spouses, children, siblings and parents;
children or spouses of individuals who died in the terrorist attacks of September 11, 2001 made directly through the Fund;
shareholders of Alger Global Focus Fund as of January 21, 2005 purchasing Class A Shares directly from the Fund for their existing accounts;
investors purchasing Class A Shares of the Alger Family of Funds when those purchases are made directly from the Fund (including shareholders of Class N Shares as of September 23, 2008); and
investors purchasing Class A Shares directly from the Fund which, when combined with current holdings of Class A Shares of the Alger Family of Funds offered with a sales charge, equal or exceeds $1,000,000 in the aggregate, when such Class A Shares are redeemed within 12 months of purchase.
Investors purchasing Class A Shares who may be entitled to one of the foregoing waivers should consult with their financial adviser as to their eligibility, and are required to claim and substantiate their eligibility for the waiver at the time of purchase. It is also the responsibility of shareholders redeeming shares otherwise subject to a CDSC but qualifying for a waiver of the charge to assert this status at the time of redemption. As the Distributor has no information regarding the nature of the underlying shareholders in an omnibus account (in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, a common form of holding shares among retirement plans and financial intermediaries such as brokers, advisers and third-party administrators) it cannot aid in the substantiation of any such claims for waivers. Information regarding these procedures is available by contacting the Fund at (800) 992-3863.
Any CDSC which otherwise would be imposed on redemptions of shares of the Fund will be waived with respect to (a) redemptions of shares held at the time a shareholder becomes disabled or dies, including the shares of a shareholder who owns the shares with his or her spouse as joint tenants with right of survivorship, provided that the redemption is requested within one year after the death or initial determination of disability, (b) redemptions in connection with the following retirement plan distributions: (i) lump-sum or other distributions from a qualified corporate or Keogh retirement plan following retirement, termination of employment, death or disability (or in the case of a five percent owner of the employer maintaining the plan, following attainment of age 70-1/2); (ii) required distributions from an IRA following the attainment of age 70-1/2 or from a custodial account under Section 403(b)(7) of the Internal Revenue Code of 1986, as amended, following the later of retirement or attainment of age 70-1/2; and (iii) a tax-free return of an excess contribution to an IRA, (c) systematic withdrawal payments, and (d) redemptions by the Fund of Fund shares whose value has fallen below the minimum initial investment amount. For purposes of the waiver described in (a) above, a person will be deemed “disabled” if the person is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or to be of long-continued and indefinite duration.
Class N shareholders of certain funds in the Alger Family of Funds whose shares were redesignated as Class A Shares on September 23, 2008 will not be subject to initial sales charges in connection with additional purchases of Class A Shares of the Alger Family of Funds. Due to operational limitations at certain financial intermediaries, a sales charge may be assessed unless you inform the financial intermediary at the time you make any additional purchase that you are eligible for this waiver. Notwithstanding the foregoing, shareholders investing through certain financial intermediaries may not be eligible to purchase shares without imposition of an initial sales charge through such financial intermediaries if the nature of their relationship with, and/or service received from, the financial intermediary changes. Please consult your financial representative for further details.
Reinvestment Privilege Under the Reinvestment Privilege, a shareholder who has redeemed Shares in a Fund account may reinvest all or part of the redemption proceeds in Shares of the same Fund in the same account without an initial sales charge and receive a credit for any CDSC paid on the redemption, provided the reinvestment is made within 30 days after the redemption. Reinvestment will be at the net asset value of the Fund next determined upon receipt of the proceeds and a letter requesting that this privilege be exercised, subject to confirmation of the shareholder’s status or holdings, as the case may be. You will also receive a pro rata credit for any CDSC imposed. This reinvestment privilege may be exercised only once by a shareholder. Reinvestment will not alter any capital gains tax payable on the redemption and a loss may not be allowed for tax purposes.
Sales Charge Discounts
In addition to waivers of sales charges for eligible investors, there are several ways in which any investor in Class A Shares may be eligible for a sales charge discount. Information on sales charge discounts is posted on the Fund’s website, www.alger.com.
When purchasing Class A Shares, when the dollar amount of your purchase reaches a specified level, known as a breakpoint, you are entitled to pay a discounted initial sales charge. For example, a purchase of up to $24,999 of Class A Shares of the Fund would be charged an initial charge of 5.25%, while a purchase of $25,000 would be charged an initial charge of 4.50%. There are several breakpoints, as shown in the above sales charge table for Class A Shares. The greater the investment, the greater the sales charge discount.

Prospectus 18/25

Letter of Intent A sales charge discount is also available to Class A Share investors who indicate an intent to purchase shares in an amount aggregating $25,000 or more over a 13-month period. A Letter of Intent (“LOI”) allows the Class A Share investor to qualify for a breakpoint discount now without immediately investing the aggregate dollar amount at which the breakpoint discount is offered. The investor must refer to the LOI when placing purchase orders. For purposes of an LOI, the purchase amount includes purchases by “any person” (which includes an individual, his or her spouse or domestic partner and children under the age of 21, or a trustee or other fiduciary of a single trust, estate or single fiduciary account) of shares of all classes of the funds in the Alger Family of Funds offered with a sales charge over the following 13 months. At the investor’s request, the 13-month period may begin up to 90 days before the date the LOI is signed. The minimum initial investment under the LOI is 5% of the total LOI amount. Further details are in the SAI.
Rights of Accumulation An investor in Class A Shares may be eligible for a sales charge discount by reason of Rights of Accumulation (“ROA”). With ROA, Class A Shares of the Fund may be purchased by “any person” (as defined in the immediately preceding paragraph) at a discounted sales charge as determined by aggregating the dollar amount of the new purchase and the current value (at offering price) of all shares of all classes of the funds in the Alger Family of Funds offered with a sales charge then held by such person and applying the sales charge applicable to such aggregate, as noted in the Class A sales charge chart above. In order to obtain such discount, the purchaser must provide sufficient information at the time of purchase to permit verification that the purchase qualifies for the sales charge discount. The right of accumulation is subject to modification or discontinuance at any time with respect to all shares purchased thereafter.
Additional Information about Minimum Initial Investments
The Distributor, in its sole discretion, may waive minimum initial investment requirements. Minimum initial investment and related requirements may be modified at any time, without prior notice.
There is no minimum initial investment for the following categories of eligible investors:
Any current employee of the Manager, or the Distributor, or their affiliates, and any of their immediate family members who share the same address.
Trustees of the Fund and Directors of Alger Associates, Inc., or its affiliates, and any of their immediate family members who share the same address.

Prospectus 20/25

if you want the check to be made payable to someone other than the registered owners we have on file; or
if you have changed your address on file within the past 30 days; or
if you want to add bank information to your existing account; or
if you want to change bank information on your existing account; or
to change registered account holders; or
to request a wire transfer of redemption proceeds to a bank account other than the bank account of record; or

Medallion Signature Guarantee is a guarantee by a financial institution that your signature is authentic. The financial institution accepts liability for any forgery or fraud if the signature it guarantees proves to be counterfeit. It is an ideal means to protect investors and their assets. A notarization by a Notary Public is not an acceptable substitute.

If you request that your redemption proceeds be wired to your bank account, there is generally a $10 fee per wire sent to a bank account that you had previously designated on the Fund’s records, and generally a $15 fee per wire sent to a bank account not previously designated on the Fund’s records. Fed wire requests to a bank account not previously designated on the Fund’s records must be made in writing, and require a Medallion signature guarantee.
Online: You can redeem shares from an existing Fund account. Go to www.alger.com and follow the online instructions.
By Financial Intermediary: Call or visit your broker-dealer, investment adviser, bank or other financial institution.
Automatic Withdrawal Plan
The Systematic Withdrawal Plan allows you to receive regular monthly, quarterly or annual payments. Your account value must be at least $10,000 at the time you begin participation in the Plan, and the payments must be for $50 or more.
The maximum monthly withdrawal is 1% of the account value in the Fund at the time you begin participation in the Plan.
Limitations on Excessive Trading
The Fund invests predominantly in U.S.-traded, highly liquid securities for which current New York Stock Exchange closing prices are readily available on a daily basis. The Fund will determine a fair value for portfolio securities for which current market closing prices are not readily available or otherwise require fair valuation in the circumstances discussed under “Net Asset Value.” As a result, the Manager believes that there is little incentive for investors to engage in frequent and/or short-term trading (often referred to as market-timing) to benefit from “stale” pricing. Nonetheless, the presence of small capitalization and medium capitalization securities and/or foreign securities in the Fund and other circumstances may invite frequent and/or short-term trading by Fund shareholders, for whatever reason implemented. Active trading may be attempted and may, if carried out on a large scale, impose burdens on the Fund’s portfolio managers, interfere with the efficient management of the Fund, increase the Fund’s transaction costs, administrative costs or tax liability or otherwise be detrimental to the interests of the Fund and its other shareholders. The Fund therefore discourage market timing, and to the extent possible monitor for market timing patterns.
The Board has adopted policies and procedures to discourage frequent and/or short-term trading of Fund shares and will generally not accommodate such practices. These policies and procedures allow the Fund to reject purchase or exchange orders, on a temporary or permanent basis, or redeem all Fund shares from investors that the Manager believes, in its reasonable business judgment, are engaging in frequent and/or short-term trading in Fund shares or shares of other funds sponsored by the Manager that is detrimental to the Fund involved. If the Fund rejects your purchase or exchange order, you will not be able to execute that transaction, and neither the Fund nor the Manager will be responsible for any losses you may suffer as a result.
In order to detect significant market timing, the Manager, in accordance with policies and procedures approved by the Board, will, among other things, seek to monitor overall subscription, redemption and exchange activity, and isolate significant daily activity to determine if there appears to be market timing activity in an individual portfolio.
Under these policies and procedures, the Fund generally prohibits more than two purchases and sales or exchanges of its shares within a 90-day calendar period. The following transactions are excluded when determining whether trading activity is excessive: (i) transactions associated with systematic investment and withdrawal plans; (ii) transactions through firm-sponsored,

Prospectus 21/25

discretionary asset allocation or wrap programs; and (iii) transactions subject to the trading policy of an intermediary that the Fund deems materially similar to the Fund’s policy. 
If, based on the Fund’s policies and procedures, the Manager determines that a shareholder is engaged in, or has engaged in, market timing or excessive trading, the Manager, on behalf of the Fund, may place a temporary or permanent block on all further purchases or exchanges of Fund shares.  Multiple accounts under common ownership or control may be considered one account for the purpose of determining a pattern of excessive trading, short-term market timing or other abusive trading practices.  The Fund will also utilize fair value pricing in an effort to reduce arbitrage opportunities available to short-term traders.
Due to the complexity involved in identifying excessive trading and market timing activity, there can be no guarantee that the Fund will be able to identify and restrict such activity in all cases.  Additionally, it is more difficult for the Fund to monitor the trading activity of beneficial owners of Fund shares who hold those shares through third-party 401(k) and other group retirement plans and other omnibus arrangements maintained by broker/dealers and other intermediaries.  Omnibus account arrangements permit multiple investors to aggregate their respective share ownership positions and purchase, redeem and exchange Fund shares in a single account. 
In certain circumstances the Fund may accept frequent trading restrictions of intermediaries that differ from the Fund’s policies and procedures. Such frequent trading restrictions of intermediaries may be more or less restrictive than the Fund’s policies and procedures. Since such intermediaries execute or administer transactions with many fund families, it may be impractical for them to enforce a particular fund’s frequent trading or exchange policy. These alternate trading restrictions would be authorized only if the Fund believes that the alternate restrictions would provide reasonable protection to the Fund and its shareholders; however the Fund does not monitor intermediaries’ frequent trading restrictions.  The Fund reserves the right to prohibit any purchase, sale or exchange of its shares that the Fund believes may be disruptive to the Fund or its long-term investors.
Disclosure of Portfolio Holdings
For a discussion of the Fund’s policies and procedures regarding the selective disclosure of its portfolio holdings, please see the SAI. The Fund makes publicly available its month-end top 10 holdings with a 10 day lag and its month-end full portfolio with a 60 day lag on its website www.alger.com.
Other Information
In Kind Redemptions. The Fund may redeem some of your shares “in kind,” which means that some of the proceeds will be paid with securities the Fund owns instead of cash. The Fund has elected to be governed by rule 18f-1 under the 1940 Act, pursuant to which the Fund is obligated to redeem shares solely in cash up to the lesser of $250,000 or 1% of the net assets of the Fund during any 90-day period for any one shareholder. If you receive securities, you should expect to incur brokerage or other charges in converting the securities to cash. If the Fund pays large redemptions in cash, these transactions may increase the Fund’s transaction costs and detract from the Fund’s performance. Large purchases pose similar risks.
Shares may be worth more or less when you redeem them than they were at the time you bought them. For tax purposes, this means that when you redeem them you may realize a short- or long-term capital gain or loss, depending upon how long you have held the shares.
If you are a participant in a retirement plan, such as a 401(k) plan, and you purchase shares in the Fund through an administrator or trustee (“Plan Administrator”) that maintains a master or “omnibus” account with one or more funds for trading on behalf of retirement plans and their participants, the Plan Administrator may apply purchase and exchange limitations which are different than the limitations discussed herein. These limitations may be more or less restrictive than the limitations imposed by the Fund. Consult with your Plan Administrator to determine what purchase and exchange limitations may be applicable to your transactions in the Fund through your retirement plan.
The Fund and the Transfer Agent have reasonable procedures in place to determine that instructions submitted by telephone are genuine. They include requesting personal identification and recording calls. If the Fund and Transfer Agent follow these procedures, they are not liable for acting in good faith on telephone instructions.
Other Payments by the Fund. Certain Financial Intermediaries perform networking, sub-transfer agency, sub-accounting, recordkeeping and/or administrative services for their clients that would otherwise be performed by the transfer agent, UMB Fund Services, Inc. (the “Transfer Agent”). In addition to fees that the Fund may pay to a Financial Intermediary for distribution (12b-1) and shareholder servicing, and fees the Fund pay to the Transfer Agent, the Distributor, on behalf of the Fund, may enter into agreements with Financial Intermediaries pursuant to which the Fund will pay a Financial Intermediary for such services. These payments are generally based on either (1) a percentage of the average daily net assets of Fund shareholders serviced by a Financial Intermediary or (2) a fixed dollar amount for each account serviced by a Financial Intermediary. The aggregate amount of these payments may be substantial.

Prospectus 22/25

The Distributor may pay partnership and/or sponsorship fees to support seminars, conferences, and other programs designed to educate intermediaries about the Fund and may cover the expenses associated with attendance at such meetings, including travel costs. The Distributor also may pay fees related to obtaining data regarding Financial Intermediary or financial advisor activities to assist the Distributor with sales reporting, business intelligence, and training and education opportunities. These payments and activities are intended to provide an incentive to Financial Intermediaries to sell the Fund by educating them about the Fund and helping defray the costs associated with offering the Fund. These payments may create a conflict of interest by influencing the Financial Intermediary to recommend the Fund over another investment. Ask your salesperson or visit your Financial Intermediary’s website for more information. The amount of any payments described by this paragraph is determined by the Manager or the Distributor, and all such amounts are paid out of their available assets, and not paid by you or the Fund. As a result, the total expense ratio of the Fund will not be affected by any such payments.
Additional Compensation. From time to time the Distributor, at its expense from its own resources, may compensate Financial Intermediaries who are instrumental in effecting investments by their clients or customers in the Fund, in an amount up to 1% of the value of those investments. The Distributor may also from time to time, at its expense from its own resources, make payments to Financial Intermediaries that provide shareholder servicing, or transaction processing, with such payments structured as a percentage of gross sales, a percentage of net assets, and/or as a fixed dollar amount (the latter as a per account fee or as reimbursement for transactions processing and transmission charges). The Distributor determines whether to make any additional cash payments and the amount of any such payments in response to requests from Financial Intermediaries, based on factors the Distributor deems relevant. Factors considered by the Distributor generally include the Financial Intermediary’s reputation, ability to attract and retain assets for the Fund, expertise in distributing a particular class of shares of the Fund, entry into target markets, and/or quality of service. In addition, the Distributor may make payments to dealer firms in the form of payments for marketing support, seminar support, training meetings, or comparable expenses in the discretion of the Distributor. Please contact your Financial Intermediary for details about revenue sharing payments it may receive. Any payments described above will not change the price paid by investors for the purchase of shares of the Fund or the amount of proceeds received by the Fund on the sale of shares.
Redemptions by the Fund. If your account, excluding asset-based fee program accounts and accounts held with certain intermediaries, falls below the minimum initial investment amount of the share class in which you are invested, the Fund may redeem all the Fund shares within your account after giving you 60 days’ prior written notice. You may avoid having your account redeemed during the notice period by bringing the account value up to the minimum initial investment amount.
The Fund and its agents reserve the right at any time to reject or cancel all or any part of any purchase or exchange order and to redeem all Fund shares if it suspects the shareholder is engaged in, or has engaged in, abusive trading practices and/or violations of any applicable securities laws. When an exchange request in respect of Fund shares is rejected, such shares may be redeemed from the Fund on request of the shareholder. In addition, the Fund reserves the right to modify any terms or conditions of purchase of shares of the Fund or suspend, change or withdraw all or any part of the offering made by this prospectus. If the Fund rejects your purchase or exchange order, you may not be able to execute that transaction, and the Fund and its agents will not be responsible for any losses you may suffer as a result.
Lost Shareholders, Inactive Accounts and Unclaimed Property. It is important that the Fund maintain a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned to the Fund. Based upon statutory requirements for returned mail, the Fund will attempt to locate the shareholder or rightful owner of the account. If the Fund is unable to locate the shareholder, then it will determine whether the shareholder’s account would legally be considered abandoned. Your mutual fund account may be transferred to the state government of your state of residence if no shareholder initiated activity occurs within your account during the “inactivity period” specified in your state’s abandoned property laws. The Fund is legally obligated to escheat (or transfer) abandoned property to the appropriate state’s unclaimed property administrator in accordance with statutory requirements. The shareholder’s last known address of record determines which state has jurisdiction. If you hold your account directly at the Transfer Agent, please proactively contact the Transfer Agent toll-free at (800) 992-3863 at least annually to ensure your account remains in active status. You may also update your contact information through your Alger access account online at www.alger.com.
If you are a resident of the state of Texas, you may designate a representative to receive notifications that, due to inactivity, your mutual fund account assets may be delivered to the Texas Comptroller. Please contact the Transfer Agent if you wish to complete a Texas Designation of Representative form.
Householding. To reduce expenses, only one copy of most financial reports and prospectuses may be mailed to households, even if more than one person in a household holds shares of the Fund. Call an Alger Funds Representative at (800) 992-3863 if you need additional copies of financial reports or prospectuses, or download them at www.alger.com. If you do not want the mailing of these documents to be combined with those for other members of your household, contact The Alger Funds in writing at Alger Family of Funds, c/o UMB Fund Services, Inc., P.O. Box 2175, Milwaukee, WI  53212-2175.

right of reinstatement).
Employer-sponsored retirement plans (e.g., 401(k) plans, 457 plans, employer-sponsored 403(b) plans, profit sharing and money purchase pension plans

*Also referred to as an “initial sales charge.”
Edward D. Jones & Co. (“Edward Jones”)
Policies Regarding Transactions Through Edward Jones
The following information has been provided by Edward Jones:
Effective on or after March 1, 2021, the following information supersedes prior information with respect to transactions and positions held in fund shares through an Edward Jones system. Clients of Edward Jones (also referred to as “shareholders”) purchasing fund shares on the Edward Jones commission and fee-based platforms are eligible only for the following sales charge discounts (also referred to as “breakpoints”) and waivers, which can differ from discounts and waivers described elsewhere in the mutual fund prospectus or statement of additional information ("SAI") or through another broker-dealer. In all instances, it is the shareholder’s responsibility to inform Edward Jones at the time of purchase of any relationship, holdings of the Alger Funds, or other facts qualifying the purchaser for discounts or waivers. Edward Jones can ask for documentation of such circumstance. Shareholders should contact Edward Jones if they have questions regarding their eligibility for these discounts and waivers.
Breakpoints
Breakpoint pricing, otherwise known as volume pricing, at dollar thresholds as described in the prospectus.
Rights of Accumulation (“ROA”)
The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except certain money market funds and
any assets held in group retirement plans) of the Alger Family of Funds held by the shareholder or in an account grouped by Edward Jones with other
accounts for the purpose of providing certain pricing considerations (“pricing groups”). If grouping assets as a shareholder, this includes all share classes
held on the Edward Jones platform and/or held on another platform. The inclusion of eligible fund family assets in the ROA calculation is dependent on the
shareholder notifying Edward Jones of such assets at the time of calculation. Money market funds are included only if such shares were sold with a sales
charge at the time of purchase or acquired in exchange for shares purchased with a sales charge.
The employer maintaining a SEP IRA plan and/or SIMPLE IRA plan may elect to establish or change ROA for the IRA accounts associated with the plan to a
plan-level grouping as opposed to including all share classes at a shareholder or pricing group level.
ROA is determined by calculating the higher of cost minus redemptions or market value (current shares x NAV).
Letter of Intent (“LOI”)
Through a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period from
the date Edward Jones receives the LOI. The LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in
combination with the value that the shareholder intends to buy over a 13-month period to calculate the front-end sales charge and any breakpoint discounts.
Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the total amount. The
inclusion of eligible fund family assets in the LOI calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation.
Purchases made before the LOI is received by Edward Jones are not adjusted under the LOI and will not reduce the sales charge previously paid. Sales
charges will be adjusted if LOI is not met.
If the employer maintaining a SEP IRA plan and/or SIMPLE IRA plan has elected to establish or change ROA for the IRA accounts associated with the plan to a
plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer.
Sales Charge Waivers
Sales charges are waived for the following shareholders and in the following situations:
Associates of Edward Jones and its affiliates and their family members who are in the same pricing group (as determined by Edward Jones under its
policies and procedures) as the associate. This waiver will continue for the remainder of the associate’s life if the associate retires from Edward Jones in
good-standing and remains in good standing pursuant to Edward Jones' policies and procedures.
Shares purchased in an Edward Jones fee-based program.
Shares purchased through reinvestment of capital gains distributions and dividend reinvestment.
Shares purchased from the proceeds of redeemed shares of the same fund family so long as the following conditions are met: 1) the proceeds are from
the sale of shares within 60 days of the purchase, and 2) the sale and purchase are made in the same share class and the same account or the purchase is
made in an individual retirement account with proceeds from liquidations in a non-retirement account.

Prospectus A-5/A-8

Sales Charge Waivers

applicable sales charge as disclosed in the prospectus.
Exchanges from Class C shares to Class A shares of the same fund, generally, in the 84th month following the anniversary of the purchase date or earlier
at the discretion of Edward Jones.
Contingent Deferred Sales Charge (“CDSC”) Waivers

to pay the CDSC except in the following conditions:
The death or disability of the shareholder
Systematic withdrawals with up to 10% per year of the account value
Return of excess contributions from an Individual Retirement Account (IRA)
Shares sold as part of a required minimum distribution for IRA and retirement accounts if the redemption is taken in or after the year the shareholder

The Fund and Fred Alger Management, LLC (the “Manager”) have adopted fee breakpoints for the Fund. The advisory fee for assets up to $2 billion is .81%, for assets between $2 billion and $3 billion is .65%, for assets between $3 billion and $4 billion is .60%, for assets between $4 billion and $5 billion is .55%, and for assets in excess of $5 billion is .45%. The actual rate paid as a percentage of average daily net assets for the year ended October 31, 2021 was .72%.
Example
The following examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The examples assume that you invest $10,000 in the Fund for the time periods indicated, that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions you would pay the following expenses whether or not you redeemed your shares at the end of each period:
 
1 Year

$850
$1,856
Portfolio Turnover
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 78.70% of the average value of its portfolio.
Principal Investment Strategy
The Manager believes companies undergoing Positive Dynamic Change offer the best investment opportunities. Positive Dynamic Change refers to companies realizing High Unit Volume Growth or companies undergoing Positive Lifecycle Change. High Unit Volume Growth companies are traditional growth companies experiencing, for example, rapidly growing demand or market dominance. Positive Lifecycle Change companies are, for example, companies benefitting from new regulations, a new product innovation or new management.

Prospectus 2/73

Under normal market circumstances, the Fund invests at least 85% of its net assets, plus any borrowings for investment purposes, in equity securities of companies of any market capitalization that the Manager believes demonstrate promising growth potential. Equity securities include common or preferred stocks that are listed on U.S. or foreign exchanges.
The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including the information technology, healthcare, consumer discretionary, and communication services sectors.
The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive.
The Fund can invest in foreign securities.
Principal Risks
An investment in the Fund involves risks. The Fund’s share price may go down, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following is a summary description of principal risks involved in investing in the Fund.
Investment Risk – An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest.
Market Risk – Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, recessions, or other events could have a significant impact on the Fund and its investments.
Equity Securities Risk – As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund’s price per share will fluctuate due to changes in the market prices of its investments. Also, the Fund’s investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds.
Growth Stocks Risk – Prices of growth stocks tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value.
Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility.
Technology Companies Risk – The Fund may have a significant portion of its assets invested in securities of technology-related companies. Therefore, the Fund may be more susceptible to particular risks that may affect companies in the information technology sector and technology-related sectors than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole. Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of technology related companies’ securities may fall or fail to rise. Many technology related companies’ securities have historically been more volatile than other securities, especially over the short term.
Healthcare Companies Risk – The Fund may have a significant portion of its assets invested in securities of healthcare companies. At times, the performance of healthcare companies will lag the performance of other industries or the broader market as a whole, and the performance of such companies may be more volatile. Healthcare companies may also be significantly affected by intense competition, aggressive pricing, government regulation, technological innovations, product obsolescence, patent considerations, product compatibility and consumer preferences.
Consumer Discretionary Sector Risk – The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns.

Prospectus 3/73

Communications Services Sector Risk – Communication services companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.
Foreign Securities Risk – The Fund’s performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing audit, regulatory, and legal standards and lack of financial reporting standards.

When a Fund is co-managed, the responsibilities of such portfolio managers may be shared, divided or otherwise assigned based on various factors including, but not limited to, level of Fund assets to be managed, their overall experience, their sector expertise, and such other factors as the Manager believes is most efficient and effective. In all cases, each portfolio manager collaborates with the other portfolio manager(s) and analysts to develop overall strategy, outlook, and themes, which impact industry, sector and security allocations in the Fund. Responsibilities amongst portfolio managers may be fully or partially allocated to one of the portfolio managers for the purposes of day-to-day portfolio management and stock selection, implementation of trades, strategic and performance oversight, risk management, or oversight of guidelines; whether externally driven or internally developed by the Manager.
Shareholder Information
Purchasing and Redeeming Fund Shares
The Fund’s Class I and R Shares are not subject to a minimum initial investment. Class I Shares are an investment vehicle principally for institutional investors such as registered investment advisers, banks, trust companies, and other financial institutions, for investments in employee benefit plans, or for advisory platform investors who pay a separate fee to such institution for the right to invest. Class R Shares are an investment vehicle principally for retirement and benefit plans investing through financial institutions.
Investors may purchase or redeem Fund shares on any business day through a financial intermediary, which may include an investor’s selected broker-dealer, investment adviser, or other financial institution or professional.
Tax Information
The Fund’s distributions may be taxable as ordinary income or capital gains. The Fund is actively managed, and as a result, investors may receive capital gains distributions annually.
Payments to Broker-Dealers and Other Financial Intermediaries
If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or the Manager or the Fund’s distributor may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your financial professional to recommend the Fund over another investment. Ask your financial professional or visit your financial intermediary’s website for more information.

The Fund and Fred Alger Management, LLC (the “Manager”) have adopted fee breakpoints for the Fund. The advisory fee for assets up to $2 billion is .81%, for assets between $2 billion and $3 billion is .65%, for assets between $3 billion and $4 billion is .60%, for assets between $4 billion and $5 billion is .55%, and for assets in excess of $5 billion is .45%. The actual rate paid as a percentage of average daily net assets for the year ended October 31, 2021 was .72%.
**
The Manager has contractually agreed to waive fees or to reimburse Fund expenses (excluding acquired fund fees and expenses, dividend expense on short sales, borrowing costs, interest, taxes, brokerage and extraordinary expenses, to the extent applicable) through February 29, 2024 to the extent necessary to limit the total annual fund operating expenses of the Class Y Shares of the Fund to .75% of the class’s average daily net assets. This expense reimbursement may only be amended or terminated prior to its expiration date by agreement between the Manager and the Fund’s Board of Trustees, and will terminate automatically in the event of termination of the Investment Advisory Agreement. The Manager may, during the term of the contract, recoup any fees waived or expenses reimbursed pursuant to the contract; however, the Fund will only make repayments to the Manager if such repayment does not cause the Fund’s expense ratio after the repayment is taken into account, to exceed both (i) the expense cap in place at the time such amounts were waived or reimbursed, and (ii) the Fund’s current expense cap. Such recoupment is limited to two years from the date the amount is initially waived or reimbursed.
Example
The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The one-year example and the first two years of the three-, five- and ten-year examples are based on net operating expenses, which reflect the contractual expense limitation agreed to by the Manager Although your actual costs may be higher or lower, based on these assumptions you would pay the following expenses whether or not you redeemed your shares at the end of each period:
 
1 Year

5 Years
10 Years
Class Y
$77
$244
$431
$970
Portfolio Turnover
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 78.70% of the average value of its portfolio.
Principal Investment Strategy
The Manager believes companies undergoing Positive Dynamic Change offer the best investment opportunities. Positive Dynamic Change refers to companies realizing High Unit Volume Growth or companies undergoing Positive Lifecycle Change. High Unit Volume Growth companies are traditional growth companies experiencing, for example, rapidly growing demand or market

Prospectus 6/73

dominance. Positive Lifecycle Change companies are, for example, companies benefitting from new regulations, a new product innovation or new management.
Under normal market circumstances, the Fund invests at least 85% of its net assets, plus any borrowings for investment purposes, in equity securities of companies of any market capitalization that the Manager believes demonstrate promising growth potential. Equity securities include common or preferred stocks that are listed on U.S. or foreign exchanges.
The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including the information technology, healthcare, consumer discretionary, and communication services sectors.
The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive.
The Fund can invest in foreign securities.
Principal Risks
An investment in the Fund involves risks. The Fund’s share price may go down, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following is a summary description of principal risks involved in investing in the Fund.
Investment Risk – An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest.
Market Risk – Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, recessions, or other events could have a significant impact on the Fund and its investments.
Equity Securities Risk – As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund’s price per share will fluctuate due to changes in the market prices of its investments. Also, the Fund’s investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds.
Growth Stocks Risk – Prices of growth stocks tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value.
Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility.
Technology Companies Risk – The Fund may have a significant portion of its assets invested in securities of technology-related companies. Therefore, the Fund may be more susceptible to particular risks that may affect companies in the information technology sector and technology-related sectors than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole. Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of technology related companies’ securities may fall or fail to rise. Many technology related companies’ securities have historically been more volatile than other securities, especially over the short term.
Healthcare Companies Risk – The Fund may have a significant portion of its assets invested in securities of healthcare companies. At times, the performance of healthcare companies will lag the performance of other industries or the broader market as a whole, and the performance of such companies may be more volatile. Healthcare companies may also be significantly affected by intense competition, aggressive pricing, government regulation, technological innovations, product obsolescence, patent considerations, product compatibility and consumer preferences.

Prospectus 7/73

Consumer Discretionary Sector Risk – The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns.
Communications Services Sector Risk – Communication services companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.
Foreign Securities Risk – The Fund’s performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing audit, regulatory, and legal standards and lack of financial reporting standards.

The Manager has contractually agreed to waive fees or to reimburse Fund expenses (excluding acquired fund fees and expenses, dividend expense on short sales, borrowing costs, interest, taxes, brokerage and extraordinary expenses, to the extent applicable) through February 29, 2024 to the extent necessary to limit the total annual fund operating expenses of the Class Z-2 Shares of the Fund to .85% of the class’s average daily net assets. This expense reimbursement may only be amended or terminated prior to its expiration date by agreement between the Manager and the Fund’s Board of Trustees, and will terminate automatically in the event of termination of the Investment Advisory Agreement. The Manager may, during the term of the contract, recoup any fees waived or expenses reimbursed pursuant to the contract; however, the Fund will only make repayments to the Manager if such repayment does not cause the Fund’s expense ratio after the repayment is taken into account, to exceed both (i) the expense cap in place at the time such amounts were waived or reimbursed, and (ii) the Fund’s current expense cap. Such recoupment is limited to two years from the date the amount is initially waived or reimbursed.

Portfolio Turnover
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 78.70% of the average value of its portfolio.
Principal Investment Strategy
The Manager believes companies undergoing Positive Dynamic Change offer the best investment opportunities. Positive Dynamic Change refers to companies realizing High Unit Volume Growth or companies undergoing Positive Lifecycle Change.

The minimum initial investment may also be waived for direct shareholders investing through an intermediary with aggregate assets of $125 million or more invested in the family of funds advised by the Manager and for investment advisory clients of the Manager or its affiliates who hold direct accounts.
Investors may purchase or redeem Fund shares on any business day through a financial intermediary, which may include an investor’s selected broker-dealer, investment adviser, or other financial institution or professional, or directly with the Fund’s transfer agent.
Tax Information
The Fund’s distributions may be taxable as ordinary income or capital gains. The Fund is actively managed, and as a result, investors may receive capital gains distributions annually.
Payments to Broker-Dealers and Other Financial Intermediaries
If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or the Manager or the Fund’s distributor may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your financial professional to recommend the Fund over another investment. Ask your financial professional or visit your financial intermediary’s website for more information.

Portfolio Turnover
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 107.82% of the average value of its portfolio.
Principal Investment Strategy
Fred Alger Management, LLC (the “Manager”) believes companies undergoing Positive Dynamic Change offer the best investment opportunities. Positive Dynamic Change refers to companies realizing High Unit Volume Growth or companies undergoing Positive Lifecycle Change. High Unit Volume Growth companies are traditional growth companies experiencing, for example, rapidly growing demand or market dominance. Positive Lifecycle Change companies are, for example, companies benefitting from new regulations, a new product innovation or new management.
Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies of any market capitalization that the Manager believes demonstrate promising growth potential. Equity securities include common or preferred stocks that are listed on U.S. or foreign exchanges.
As a focus fund, the Fund intends to invest a substantial portion of its assets in a smaller number of issuers. Generally the Fund will own approximately 50 holdings. Fund holdings may occasionally differ from this number for a variety of reasons, including, among others, because of extreme market volatility, such as when the Fund has entered a temporary defensive position. Additionally, the

Prospectus 14/73

Fund may temporarily exceed the stated number of holdings when it acquires a new holding and determines that it is in the best interests of shareholders to sell an existing holding over a period of time, instead of immediately selling the entire holding.
The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including the information technology, consumer discretionary, communication services, and healthcare sectors.
The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive. As a result, the Fund may engage in active trading of portfolio securities.
The Fund can invest in foreign securities.
Principal Risks
An investment in the Fund involves risks. The Fund’s share price may go down, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following is a summary description of principal risks involved in investing in the Fund.
Investment Risk – An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest.
Market Risk – Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, recessions, or other events could have a significant impact on the Fund and its investments.
Equity Securities Risk – As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund’s price per share will fluctuate due to changes in the market prices of its investments. Also, the Fund’s investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds.
Growth Stocks Risk – Prices of growth stocks tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value.
Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility.
Technology Companies Risk – The Fund may have a significant portion of its assets invested in securities of technology-related companies. Therefore, the Fund may be more susceptible to particular risks that may affect companies in the information technology sector and technology-related sectors than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole. Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of technology related companies’ securities may fall or fail to rise. Many technology related companies’ securities have historically been more volatile than other securities, especially over the short term.
Consumer Discretionary Sector Risk – The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns.
Healthcare Companies Risk – The Fund may have a significant portion of its assets invested in securities of healthcare companies. At times, the performance of healthcare companies will lag the performance of other industries or the broader market as a whole, and the performance of such companies may be more volatile. Healthcare companies may also be significantly affected by intense competition, aggressive pricing, government regulation, technological innovations, product obsolescence, patent considerations, product compatibility and consumer preferences.

Prospectus 15/73

Communications Services Sector Risk – Communication services companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.
Small Number of Holdings Risk – Under normal circumstances, the Fund invests in a small number of issuers. Therefore, the Fund’s performance may be more vulnerable to changes in the market value of a single issuer and more susceptible to risks associated with a single economic, political, or regulatory occurrence than a fund that has a higher number of holdings.
Foreign Securities Risk – The Fund’s performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing audit, regulatory, and legal standards and lack of financial reporting standards.
Portfolio Turnover (Active Trading) Risk – Because the Fund may engage in active trading of portfolio securities, it may incur increased transaction costs and brokerage commissions, both of which can lower the actual return on an investment. Active trading may also increase short-term gains and losses, which may affect the taxes a shareholder has to pay.
Performance
The following bar chart and the table beneath it provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for the indicated periods compare with those of an appropriate benchmark of market performance. Previously, the Fund followed different investment strategies under the name “Alger Large Cap Growth Institutional Fund” and was managed by different portfolio managers. Performance prior to December 31, 2012 reflects those management styles and does not reflect the current investment personnel and strategies of the Fund. On October 15, 2018, Alger Capital Appreciation Focus Fund changed its name to Alger Focus Equity Fund. The Fund’s past performance (before and after taxes) is not necessarily an indication of how it will perform in the future. Updated performance information is available on the Fund’s website www.alger.com.

In the foregoing table, after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. The after-tax returns shown may not be relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. A “Return After Taxes on Distributions and Sale of Fund Shares” may sometimes be higher than the other two return figures; this happens when there is a capital loss on redemptions, giving rise to a tax benefit to the shareholder.

In all cases, each portfolio manager collaborates with the other portfolio manager(s) and analysts to develop overall strategy, outlook, and themes, which impact industry, sector and security allocations in the Fund. Responsibilities amongst portfolio managers may be fully or partially allocated to one of the portfolio managers for the purposes of day-to-day portfolio management and stock selection, implementation of trades, strategic and performance oversight, risk management, or oversight of guidelines; whether externally driven or internally developed by the Manager.
Shareholder Information
Purchasing and Redeeming Fund Shares

Investors may purchase or redeem Fund shares on any business day through a financial intermediary, which may include an investor’s selected broker-dealer, investment adviser, or other financial institution or professional.
Tax Information
The Fund’s distributions may be taxable as ordinary income or capital gains. The Fund is actively managed, and as a result, investors may receive capital gains distributions annually.

Fred Alger Management, LLC (the “Manager”) has contractually agreed to waive fees or to reimburse Fund expenses (excluding acquired fund fees and expenses, dividend expense on short sales, borrowing costs, interest, taxes, brokerage and extraordinary expenses, to the extent applicable) through February 29, 2024 to the extent necessary to limit the total annual fund operating expenses of the Class Y Shares of the Fund to .58% of the class’s average daily net assets. This expense reimbursement may only be amended or terminated prior to its expiration date by agreement between the Manager and the Fund’s Board of Trustees, and will terminate automatically in the event of termination of the Investment Advisory Agreement. The Manager may, during the term of the contract, recoup any fees waived or expenses reimbursed pursuant to the contract; however, the Fund will only make repayments to the Manager if such repayment does not cause the Fund’s expense ratio after the repayment is taken into account, to exceed both (i) the expense cap in place at the time such amounts were waived or reimbursed, and (ii) the Fund’s current expense cap. Such recoupment is limited to two years from the date the amount is initially waived or reimbursed.
Example
The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The one-year example and the first two years of the three-, five- and ten-year examples are based on net operating expenses, which reflect the contractual expense limitation agreed to by the Manager. Although your actual costs may be higher or lower, based on these assumptions you would pay the following expenses whether or not you redeemed your shares at the end of each period:

Portfolio Turnover
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 107.82% of the average value of its portfolio.

Positive Dynamic Change refers to companies realizing High Unit Volume Growth or companies undergoing Positive Lifecycle Change.

Fred Alger Management, LLC (the “Manager”) has contractually agreed to waive fees or to reimburse Fund expenses (excluding acquired fund fees and expenses, dividend expense on short sales, borrowing costs, interest, taxes, brokerage and extraordinary expenses, to the extent applicable) through February 29, 2024 to the extent necessary to limit the total annual fund operating expenses of the Class Z Shares of the Fund to .63% of the class’s average daily net assets. This expense reimbursement may only be amended or terminated prior to its expiration date by agreement between the Manager and the Fund’s Board of Trustees, and will terminate automatically in the event of termination of the Investment Advisory Agreement. The Manager may, during the term of the contract, recoup any fees waived or expenses reimbursed pursuant to the contract; however, the Fund will only make repayments to the Manager if such repayment does not cause the Fund’s expense ratio after the repayment is taken into account, to exceed both (i) the expense cap in place at the time such amounts were waived or reimbursed, and (ii) the Fund’s current expense cap. Such recoupment is limited to two years from the date the amount is initially waived or reimbursed.
Example
The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions you would pay the following expenses whether or not you redeemed your shares at the end of each period:

Portfolio Turnover
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 107.82% of the average value of its portfolio.
Principal Investment Strategy
The Manager believes companies undergoing Positive Dynamic Change offer the best investment opportunities. Positive Dynamic Change refers to companies realizing High Unit Volume Growth or companies undergoing Positive Lifecycle Change. High Unit Volume Growth companies are traditional growth companies experiencing, for example, rapidly growing demand or market dominance. Positive Lifecycle Change companies are, for example, companies benefitting from new regulations, a new product innovation or new management.
Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies of any market capitalization that the Manager believes demonstrate promising growth potential. Equity securities include common or preferred stocks that are listed on U.S. or foreign exchanges.

As a focus fund, the Fund intends to invest a substantial portion of its assets in a smaller number of issuers. Generally the Fund will own approximately 50 holdings. Fund holdings may occasionally differ from this number for a variety of reasons, including, among others, because of extreme market volatility, such as when the Fund has entered a temporary defensive position. Additionally, the Fund may temporarily exceed the stated number of holdings when it acquires a new holding and determines that it is in the best interests of shareholders to sell an existing holding over a period of time, instead of immediately selling the entire holding.
The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including the information technology, consumer discretionary, communication services, and healthcare sectors.
The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive. As a result, the Fund may engage in active trading of portfolio securities.
The Fund can invest in foreign securities.
Principal Risks
An investment in the Fund involves risks. The Fund’s share price may go down, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following is a summary description of principal risks involved in investing in the Fund.
Investment Risk – An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest.
Market Risk – Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, recessions, or other events could have a significant impact on the Fund and its investments.
Equity Securities Risk – As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund’s price per share will fluctuate due to changes in the market prices of its investments. Also, the Fund’s investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds.
Growth Stocks Risk – Prices of growth stocks tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value.
Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility.
Technology Companies Risk – The Fund may have a significant portion of its assets invested in securities of technology-related companies. Therefore, the Fund may be more susceptible to particular risks that may affect companies in the information technology sector and technology-related sectors than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole. Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of technology related companies’ securities may fall or fail to rise. Many technology related companies’ securities have historically been more volatile than other securities, especially over the short term.
Consumer Discretionary Sector Risk – The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns.
Healthcare Companies Risk – The Fund may have a significant portion of its assets invested in securities of healthcare companies. At times, the performance of healthcare companies will lag the performance of other industries or the broader market as a whole, and the performance of such companies may be more volatile. Healthcare companies may also be

Prospectus 24/73

significantly affected by intense competition, aggressive pricing, government regulation, technological innovations, product obsolescence, patent considerations, product compatibility and consumer preferences.
Communications Services Sector Risk – Communication services companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.
Small Number of Holdings Risk – Under normal circumstances, the Fund invests in a small number of issuers. Therefore, the Fund’s performance may be more vulnerable to changes in the market value of a single issuer and more susceptible to risks associated with a single economic, political, or regulatory occurrence than a fund that has a higher number of holdings.
Foreign Securities Risk – The Fund’s performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing audit, regulatory, and legal standards and lack of financial reporting standards.
Portfolio Turnover (Active Trading) Risk – Because the Fund may engage in active trading of portfolio securities, it may incur increased transaction costs and brokerage commissions, both of which can lower the actual return on an investment. Active trading may also increase short-term gains and losses, which may affect the taxes a shareholder has to pay.
Performance
The following bar chart and the table beneath it provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for the indicated periods compare with those of an appropriate benchmark of market performance. On October 15, 2018, Alger Capital Appreciation Focus Fund changed its name to Alger Focus Equity Fund. The Fund’s past performance (before and after taxes) is not necessarily an indication of how it will perform in the future.

When a Fund is co-managed, the responsibilities of such portfolio managers may be shared, divided or otherwise assigned based on various factors including, but not limited to, level of Fund assets to be managed, their overall experience, their sector expertise, and such other factors as the Manager believes is most efficient and effective. In all cases, each portfolio manager collaborates with the other portfolio manager(s) and analysts to develop overall strategy, outlook, and themes, which impact industry, sector and security allocations in the Fund. Responsibilities amongst portfolio managers may be fully or partially allocated to one of the portfolio managers for the purposes of day-to-day portfolio management and stock selection, implementation of trades, strategic and performance oversight, risk management, or oversight of guidelines; whether externally driven or internally developed by the Manager.
Shareholder Information
Purchasing and Redeeming Fund Shares
The Fund’s Class Z Shares are generally subject to a minimum initial investment of $500,000, which may be waived for group employer-sponsored 401(k) plans, 457 plans, employer sponsored 403(b) plans, profit-sharing and money purchase pension plans, defined benefit plans, retiree health benefit plans and non-qualified deferred compensation plans. The waiver is available only for retirement plans that hold omnibus positions, or for aggregate plan participant positions, for each Fund made available for the plan. The waiver is generally not available to non-retirement accounts, traditional and Roth Individual Retirement Accounts, Coverdell Education Savings Accounts, SEPs, SARSEPs, SIMPLE IRAs, individual 401(k) plans or individual 403(b) plans. The minimum initial investment may also be waived for direct shareholders investing through an intermediary with aggregate assets of $125 million or more invested in the family of funds advised by the Manager and for investment advisory clients of the Manager or its affiliates who hold direct accounts.
Investors may purchase or redeem Fund shares on any business day through a financial intermediary, which may include an investor’s selected broker-dealer, investment adviser, or other financial institution or professional, or directly with the Fund’s transfer agent.
Tax Information
The Fund’s distributions may be taxable as ordinary income or capital gains. The Fund is actively managed, and as a result, investors may receive capital gains distributions annually.

Payments to Broker-Dealers and Other Financial Intermediaries
If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or the Manager or the Fund’s distributor may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your financial professional to recommend the Fund over another investment. Ask your financial professional or visit your financial intermediary’s website for more information.

The examples assume that you invest $10,000 in the Fund for the time periods indicated, that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Portfolio Turnover
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 171.43% of the average value of its portfolio.
Principal Investment Strategy
The Manager believes companies undergoing Positive Dynamic Change offer the best investment opportunities. Positive Dynamic Change refers to companies realizing High Unit Volume Growth or companies undergoing Positive Lifecycle Change. High Unit Volume Growth companies are traditional growth companies experiencing, for example, rapidly growing demand or market dominance. Positive Lifecycle Change companies are, for example, companies benefitting from new regulations, a new product innovation or new management.
The Fund focuses on mid-sized companies that the Manager believes demonstrate promising growth potential. Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities of companies that, at the time of purchase of the securities, have total market capitalization within the range of companies included in the Russell Midcap Growth Index or the S&P

Prospectus 28/73

MidCap 400 Index, as reported by the indexes as of the most recent quarter-end. Both indexes are designed to track the performance of medium-capitalization stocks. At December 31, 2021, the market capitalization of the companies in these indexes ranged from $1.2 billion to $60 billion. Because of the Fund’s long-term approach to investing, it could have a significant portion of its assets invested in securities of issuers that have appreciated beyond the market capitalization thresholds noted. Equity securities include common or preferred stocks that are listed on U.S. or foreign exchanges.
The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including the information technology, industrials, consumer discretionary, and healthcare sectors.
The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive. As a result, the Fund may engage in active trading of portfolio securities.
Principal Risks
An investment in the Fund involves risks. The Fund’s share price may go down, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following is a summary description of principal risks involved in investing in the Fund.
Investment Risk – An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest.
Market Risk – Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, recessions, or other events could have a significant impact on the Fund and its investments.
Equity Securities Risk – As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund’s price per share will fluctuate due to changes in the market prices of its investments. Also, the Fund’s investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds.
Growth Stocks Risk – Prices of growth stocks tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value.
Mid Cap Securities Risk – There may be greater risk in investing in medium-capitalization companies rather than larger, more established companies due to such factors as inexperienced management and limited product lines or financial resources. It may also be difficult or impossible to liquidate a security position at a time and price acceptable to the Fund because of the potentially less frequent trading of stocks of smaller market capitalization.
Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility.

Healthcare companies may also be

significantly affected by intense competition, aggressive pricing, government regulation, technological innovations, product obsolescence, patent considerations, product compatibility and consumer preferences.
Consumer Discretionary Sector Risk – The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns.
Industrial Companies Risk – The Fund may have a significant portion of its assets invested in securities of companies in the industrial sector. Industrial companies are affected by supply and demand both for their specific product or service and for industrial sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrial sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services.
Foreign Securities Risk – The Fund’s performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing audit, regulatory, and legal standards and lack of financial reporting standards.
Portfolio Turnover (Active Trading) Risk – Because the Fund may engage in active trading of portfolio securities, it may incur increased transaction costs and brokerage commissions, both of which can lower the actual return on an investment. Active trading may also increase short-term gains and losses, which may affect the taxes a shareholder has to pay.

Shareholder Information
Purchasing and Redeeming Fund Shares
The Fund’s Class I and R Shares are not subject to a minimum initial investment. Class I Shares are an investment vehicle principally for institutional investors such as registered investment advisers, banks, trust companies, and other financial institutions, for investments in employee benefit plans, or for advisory platform investors who pay a separate fee to such institution for the right to invest. Class R Shares are an investment vehicle principally for retirement and benefit plans investing through financial institutions.
Investors may purchase or redeem Fund shares on any business day through a financial intermediary, which may include an investor’s selected broker-dealer, investment adviser, or other financial institution or professional.
Tax Information
The Fund’s distributions may be taxable as ordinary income or capital gains. The Fund is actively managed, and as a result, investors may receive capital gains distributions annually.
Payments to Broker-Dealers and Other Financial Intermediaries
If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or the Manager or the Fund’s distributor may pay the intermediary for the sale of Fund shares and related services.

The Fund and Fred Alger Management, LLC (the “Manager”) have adopted fee breakpoints for the Fund. The advisory fee for assets up to $1 billion is .76%, and for assets in excess of $1 billion is .70%. The actual rate paid as a percentage of average daily net assets for the year ended October 31, 2021 was .76%.
**
The Manager has contractually agreed to waive fees or to reimburse Fund expenses (excluding acquired fund fees and expenses, dividend expense on short sales, borrowing costs, interest, taxes, brokerage and extraordinary expenses, to the extent applicable) through February 29, 2024 to the extent necessary to limit the total annual fund operating expenses of the Class Z-2 Shares of the Fund to .99% of the class’s average daily net assets. This expense reimbursement may only be amended or terminated prior to its expiration date by agreement between the Manager and the Fund’s Board of Trustees, and will terminate automatically in the event of termination of the Investment Advisory Agreement. The Manager may, during the term of the contract, recoup any fees waived or expenses reimbursed pursuant to the contract; however, the Fund will only make repayments to the Manager if such repayment does not cause the Fund’s expense ratio after the repayment is taken into account, to exceed both (i) the expense cap in place at the time such amounts were waived or reimbursed, and (ii) the Fund’s current expense cap. Such recoupment is limited to two years from the date the amount is initially waived or reimbursed.
Example
The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions you would pay the following expenses whether or not you redeemed your shares at the end of each period:

Portfolio Turnover
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 171.43% of the average value of its portfolio.
Principal Investment Strategy
The Manager believes companies undergoing Positive Dynamic Change offer the best investment opportunities. Positive Dynamic Change refers to companies realizing High Unit Volume Growth or companies undergoing Positive Lifecycle Change. High Unit Volume Growth companies are traditional growth companies experiencing, for example, rapidly growing demand or market dominance. Positive Lifecycle Change companies are, for example, companies benefitting from new regulations, a new product innovation or new management.
The Fund focuses on mid-sized companies that the Manager believes demonstrate promising growth potential. Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities of companies that, at the time of purchase of the

Prospectus 32/73

securities, have total market capitalization within the range of companies included in the Russell Midcap Growth Index or the S&P MidCap 400 Index, as reported by the indexes as of the most recent quarter-end. Both indexes are designed to track the performance of medium-capitalization stocks. At December 31, 2021, the market capitalization of the companies in these indexes ranged from $1.2 billion to $60 billion. Because of the Fund’s long-term approach to investing, it could have a significant portion of its assets invested in securities of issuers that have appreciated beyond the market capitalization thresholds noted. Equity securities include common or preferred stocks that are listed on U.S. or foreign exchanges.
The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including the information technology, industrials, consumer discretionary, and healthcare sectors.
The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive. As a result, the Fund may engage in active trading of portfolio securities.
Principal Risks
An investment in the Fund involves risks. The Fund’s share price may go down, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following is a summary description of principal risks involved in investing in the Fund.
Investment Risk – An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest.
Market Risk – Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, recessions, or other events could have a significant impact on the Fund and its investments.
Equity Securities Risk – As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund’s price per share will fluctuate due to changes in the market prices of its investments. Also, the Fund’s investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds.
Growth Stocks Risk – Prices of growth stocks tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value.
Mid Cap Securities Risk – There may be greater risk in investing in medium-capitalization companies rather than larger, more established companies due to such factors as inexperienced management and limited product lines or financial resources. It may also be difficult or impossible to liquidate a security position at a time and price acceptable to the Fund because of the potentially less frequent trading of stocks of smaller market capitalization.
Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility.
Technology Companies Risk – The Fund may have a significant portion of its assets invested in securities of technology-related companies. Therefore, the Fund may be more susceptible to particular risks that may affect companies in the information technology sector and technology-related sectors than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole. Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of technology related companies’ securities may fall or fail to rise. Many technology related companies’ securities have historically been more volatile than other securities, especially over the short term.
Healthcare Companies Risk – The Fund may have a significant portion of its assets invested in securities of healthcare companies. At times, the performance of healthcare companies will lag the performance of other industries or the broader market as a whole, and the performance of such companies may be more volatile. Healthcare companies may also be

Prospectus 33/73

significantly affected by intense competition, aggressive pricing, government regulation, technological innovations, product obsolescence, patent considerations, product compatibility and consumer preferences.
Consumer Discretionary Sector Risk – The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns.
Industrial Companies Risk – The Fund may have a significant portion of its assets invested in securities of companies in the industrial sector. Industrial companies are affected by supply and demand both for their specific product or service and for industrial sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrial sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services.
Foreign Securities Risk – The Fund’s performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing audit, regulatory, and legal standards and lack of financial reporting standards.
Portfolio Turnover (Active Trading) Risk – Because the Fund may engage in active trading of portfolio securities, it may incur increased transaction costs and brokerage commissions, both of which can lower the actual return on an investment. Active trading may also increase short-term gains and losses, which may affect the taxes a shareholder has to pay.
Performance
The following bar chart and the table beneath it provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for the indicated periods compare with those of an appropriate benchmark of market performance.

In the foregoing table, after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. The after-tax returns shown may not be relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. A “Return After Taxes on Distributions and Sale of Fund Shares” may sometimes be higher than the other two return figures; this happens when there is a capital loss on redemptions, giving rise to a tax benefit to the shareholder.

Shareholder Information
Purchasing and Redeeming Fund Shares
The Fund’s Class Z-2 Shares are generally subject to a minimum initial investment of $500,000, which may be waived for group employer-sponsored 401(k) plans, 457 plans, employer sponsored 403(b) plans, profit-sharing and money purchase pension plans, defined benefit plans, retiree health benefit plans and non-qualified deferred compensation plans. The waiver is available only for retirement plans that hold omnibus positions, or for aggregate plan participant positions. The waiver is generally not available to non-retirement accounts, traditional and Roth Individual Retirement Accounts, Coverdell Education Savings Accounts, SEPs, SARSEPs, SIMPLE IRAs, individual 401(k) plans or individual 403(b) plans. The minimum initial investment may also be waived for direct shareholders investing through an intermediary with aggregate assets of $125 million or more invested in the family of funds advised by the Manager and for investment advisory clients of the Manager or its affiliates who hold direct accounts.
Investors may purchase or redeem Fund shares on any business day through a financial intermediary, which may include an investor’s selected broker-dealer, investment adviser, or other financial institution or professional, or directly with the Fund’s transfer agent.
Tax Information
The Fund’s distributions may be taxable as ordinary income or capital gains. The Fund is actively managed, and as a result, investors may receive capital gains distributions annually.
Payments to Broker-Dealers and Other Financial Intermediaries
If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or the Manager or the Fund’s distributor may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your financial professional to recommend the Fund over another investment. Ask your financial professional or visit your financial intermediary’s website for more information.

Example
The following examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The examples assume that you invest $10,000 in the Fund for the time periods indicated, that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Portfolio Turnover
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 41.10% of the average value of its portfolio.
Principal Investment Strategy
The Manager believes companies undergoing Positive Dynamic Change offer the best investment opportunities. Positive Dynamic Change refers to companies realizing High Unit Volume Growth or companies undergoing Positive Lifecycle Change. High Unit Volume Growth companies are traditional growth companies experiencing, for example, rapidly growing demand or market dominance. Positive Lifecycle Change companies are, for example, companies benefitting from new regulations, a new product innovation or new management.
The Fund focuses on small, fast-growing companies that the Manager believes offer innovative products, services or technologies to a rapidly-expanding marketplace. The Fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies that, at the time of purchase of the securities, have total market capitalization between (1) the higher of (a) $5 billion or (b) the company in either the Russell 2000 Growth Index or the MSCI USA Small Cap

Prospectus 36/73

Index (each, an “Index” and together, the “Indexes”) with the highest capitalization, and (2) the company in either Index with the lowest capitalization, at any time during the most recent 12-month period as reported by either Index. Both Indexes are broad-based indexes of small capitalization stocks. At December 31, 2021, the market capitalization of the companies in the Indexes ranged from $31 million to $33 billion. Because of the Fund’s long-term approach to investing, it could have a significant portion of its assets invested in securities of issuers that have appreciated beyond the market capitalization thresholds noted. Equity securities include common or preferred stocks that are listed on U.S. exchanges.
The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including the information technology, healthcare, and consumer discretionary sectors.
The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive.
The Fund can invest in foreign securities.
The Fund invests in cash (and cash equivalents) when the Fund is unable to find enough attractive long-term investments to meet its investment objective, to meet redemptions and/or when the Manager believes it is advisable to do so during times of short-term market volatility. During these times, cash (and cash equivalents) will not exceed 15% of the Fund’s assets.
Principal Risks
An investment in the Fund involves risks. The Fund’s share price may go down, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following is a summary description of principal risks involved in investing in the Fund.
Investment Risk – An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest.
Market Risk – Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, recessions, or other events could have a significant impact on the Fund and its investments.
Equity Securities Risk – As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund’s price per share will fluctuate due to changes in the market prices of its investments. Also, the Fund’s investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds.
Growth Stocks Risk – Prices of growth stocks tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value.
Small Cap Securities Risk – There may be greater risk in investing in companies with small market capitalizations rather than larger, more established companies owing to such factors as more limited product lines or financial resources or lack of management depth. It may also be difficult or impossible to liquidate a security position at a time and price acceptable to the Fund because of the potentially less frequent trading of stocks of smaller market capitalization.
Mid Cap Securities Risk – There may be greater risk in investing in medium-capitalization companies rather than larger, more established companies due to such factors as inexperienced management and limited product lines or financial resources. It may also be difficult or impossible to liquidate a security position at a time and price acceptable to the Fund because of the potentially less frequent trading of stocks of smaller market capitalization.
Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility.
Technology Companies Risk – The Fund may have a significant portion of its assets invested in securities of technology-related companies. Therefore, the Fund may be more susceptible to particular risks that may affect companies in the information technology sector and technology-related sectors than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole.

Prospectus 37/73

Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of technology related companies’ securities may fall or fail to rise. Many technology related companies’ securities have historically been more volatile than other securities, especially over the short term.
Healthcare Companies Risk – The Fund may have a significant portion of its assets invested in securities of healthcare companies. At times, the performance of healthcare companies will lag the performance of other industries or the broader market as a whole, and the performance of such companies may be more volatile. Healthcare companies may also be significantly affected by intense competition, aggressive pricing, government regulation, technological innovations, product obsolescence, patent considerations, product compatibility and consumer preferences.
Consumer Discretionary Sector Risk – The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns.
Foreign Securities Risk – The Fund’s performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing audit, regulatory, and legal standards and lack of financial reporting standards.
Cash Position Risk – At times, the Fund may hold a large cash position, which may underperform relative to equity securities.

In all cases, each portfolio manager collaborates with the other portfolio manager(s) and analysts to develop overall strategy, outlook, and themes, which impact industry, sector and security allocations in the Fund. Responsibilities amongst portfolio managers may be fully or partially allocated to one of the portfolio managers for the purposes of day-to-day portfolio management and stock selection, implementation of trades, strategic and performance oversight, risk management, or oversight of guidelines; whether externally driven or internally developed by the Manager.

The actual rate paid as a percentage of average daily net assets for the year ended October 31, 2021 was .81%.

The Manager has contractually agreed to waive fees or to reimburse Fund expenses (excluding acquired fund fees and expenses, dividend expense on short sales, borrowing costs, interest, taxes, brokerage and extraordinary expenses, to the extent applicable) through February 29, 2024 to the extent necessary to limit the total annual fund operating expenses of the Fund’s Class Z-2 Shares to .99% of the class’s average daily net assets. This expense reimbursement may only be amended or terminated prior to its expiration date by agreement between the Manager and the Fund’s Board of Trustees, and will terminate automatically in the event of termination of the Investment Advisory Agreement. The Manager may, during the term of the contract, recoup any fees waived or expenses reimbursed pursuant to the contract; however, the Fund will only make repayments to the Manager if such repayment does not cause the Fund’s expense ratio after the repayment is taken into account, to exceed both (i) the expense cap in place at the time such amounts were waived or reimbursed, and (ii) the Fund’s current expense cap. Such recoupment is limited to two years from the date the amount is initially waived or reimbursed.
Example
The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The examples assume that you invest $10,000 in the Fund for the time periods indicated, that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

A “Return After Taxes on Distributions and Sale of Fund Shares” may sometimes be higher than the other two return figures; this happens when there is a capital loss on redemptions, giving rise to a tax benefit to the shareholder.

Since January 2016
Amy Y. Zhang, CFA
Executive Vice President and Portfolio Manager
Since February 2015
When a Fund is co-managed, the responsibilities of such portfolio managers may be shared, divided or otherwise assigned based on various factors including, but not limited to, level of Fund assets to be managed, their overall experience, their sector expertise, and such other factors as the Manager believes is most efficient and effective. In all cases, each portfolio manager collaborates with the other portfolio manager(s) and analysts to develop overall strategy, outlook, and themes, which impact industry, sector and security allocations in the Fund. Responsibilities amongst portfolio managers may be fully or partially allocated to one of the portfolio managers for the purposes of day-to-day portfolio management and stock selection, implementation of trades, strategic and performance oversight, risk management, or oversight of guidelines; whether externally driven or internally developed by the Manager.

Payments to Broker-Dealers and Other Financial Intermediaries
If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or the Manager or the Fund’s distributor may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your financial professional to recommend the Fund over another investment. Ask your financial professional or visit your financial intermediary’s website for more information.

Investment Objectives, Principal Investment Strategies and Related Risks
The investment objective, principal strategy and primary risks of each Fund are discussed individually in each Fund’s Summary Section in this Prospectus. Each Fund has adopted a policy to invest at least 80% of its assets in specified securities appropriate to its name (as described in the Fund’s Summary Section in this Prospectus) and to provide shareholders with at least 60 days’ prior notice of any change with respect to this policy. Each Fund’s investment objective is a fundamental investment policy and may not be changed without shareholder approval. A Fund may, from time to time, take temporary defensive positions that are inconsistent with the Fund’s principal investment strategies in attempting to respond to adverse market, economic, political, or other conditions. A Fund may not achieve its investment objective while in a temporary defensive position.
All of a Fund’s share classes invest in the same portfolio of securities. Performance of each share class will vary from the performance of the Fund’s other share classes due to the differences in charges or expenses. A Fund’s past performance (before and after taxes) is not necessarily an indication of how it will perform in the future.
Each index used in the Summary Sections is a broad-based index designed to track a particular market or market segment. No expenses, fees or taxes are reflected in the returns for the indexes, which are unmanaged. All returns for the indexes assume reinvestment of dividends and interest of the underlying securities that make up the respective index. Investors cannot invest directly in any index.
Russell 1000 Growth Index: An unmanaged index designed to measure the performance of a subset of the largest 1,000 capitalization companies in the Russell 3000 Index with higher price-to-book ratios and higher forecasted growth values.
Russell Midcap Growth Index: An index of common stocks designed to track performance of medium-capitalization companies with greater than average growth orientation.
Russell 2000 Growth Index: An unmanaged index designed to measure the performance of a subset of the 2,000 smallest companies in the Russell 3000 Index with higher price-to-book ratios and higher forecasted growth values.
Additional Information About the Funds’ Investment Strategies and Investments
Investment Objective
Each of the Funds seeks long-term capital appreciation.
Principal Investment Strategies
The following are each Fund’s investment process and principal investment strategies. Each Fund may invest in other securities that are not its principal strategy, and such strategies and related risks are described in more detail in the Fund’s Statement of Additional Information (“SAI”).
Each Fund invests primarily in equity securities. Each Fund’s investments in equity securities are primarily in common or preferred stocks, but its equity investments may also include securities convertible into or exchangeable for equity securities (including warrants and rights) and depositary receipts. Each Fund invests primarily in companies whose securities are traded on U.S. or foreign exchanges.
Each Fund invests primarily in “growth” stocks. The Funds’ investment manager, Fred Alger Management, LLC (“Alger Management” or the “Manager”), believes that these companies tend to fall into one of two categories:
High Unit Volume Growth
Vital, creative companies that offer goods or services to a rapidly expanding marketplace. They include both established and emerging firms, exercising market dominance, offering new or improved products, or simply fulfilling an increased demand for an existing product line.
Positive Life Cycle Change
Companies experiencing a major change which is expected to produce advantageous results. These changes may be as varied as new management, products or technologies; restructuring or reorganization; regulatory change; or merger and acquisition.
Alger Mid Cap Growth Institutional Fund and Alger Small Cap Growth Institutional Fund must take into account a company’s market capitalization when considering it for investment. The market capitalization of a company is its price per share multiplied by its number of outstanding shares.

Prospectus 46/73

ESG Integration
Although a Fund does not seek to implement a specific environmental, social and governance (“ESG”), impact or sustainability strategy unless otherwise disclosed, the Manager has sought to ESG considerations into its investment process through the use of both third-party ESG specific information and its own proprietary research. Specifically, with respect to 75% of its assets under management, the Manager evaluates a company’s ESG factors and, based on such factors, may engage with the company to (i) identify drivers of poor ESG metrics; (ii) interview management with key questions about ESG issues; and (iii) evaluate the prospect of positive ESG change within a company. Upon conclusion of this engagement, a report is published to the Manager’s research database to ensure that all portfolio managers have access to the report summarizing the company’s ESG issues, the results of any meeting/interview with the company, an ESG rating of the company and any other relevant factors. The author of each report will meet with portfolio managers as necessary to discuss the ESG report and the impact the report may have on the overall investment view of the company.
The Manager may change the sources for such ESG information, including by adding or modifying the information it receives from third-party firms, selecting different third-party firms, using company provided information, or performing different or additional internal assessments. To assist with efforts to incorporate ESG considerations into the investment process, all of the Manager’s investment professionals have access to company-specific ESG reports. The Manager has established an ESG steering committee comprised of executive management and senior investment professionals to oversee this process.
ESG characteristics are not the sole considerations when making investment decisions for a Fund. Further, investors can differ in their views of what constitutes positive or negative ESG characteristics. As a result, a Fund may invest in issuers that do not reflect the beliefs and values with respect to ESG of any particular investor. ESG considerations may affect a Fund’s exposure to certain companies or industries and a Fund may forego certain investment opportunities. While the Manager views ESG considerations as having the potential to contribute to a Fund’s long-term performance, there is no guarantee that such results will be achieved.
Principal Risks
This section contains a discussion of the general risks of investing in the Funds. The “Investment Strategies and Policies” section in the SAI also includes more information about the Funds and their investments and the related risks. An investment in the Funds is not insured or guaranteed by the Federal Deposit Insurance Corporation or by any bank or governmental agency. As with any fund, an investment in the Funds involves risks. Each risk noted below is applicable to each Fund unless the specific Fund or Funds are noted in a parenthetical.
Investment Risk
An investment in a Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest.
Market Risk
Your investment in Fund shares represents an indirect investment in the securities owned by a Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, recessions, or other events could have a significant impact on a Fund and its investments.
Equity Securities Risk
As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. Each Fund’s price per share will fluctuate due to changes in the market prices of its investments. Because stock markets tend to move in cycles, stock prices overall may decline. A particular stock’s market value may decline as a result of general market conditions that are not related to the issuing company (e.g., adverse economic conditions or investor sentiment) or due to factors that affect the particular company (e.g., management performance or factors affecting the industry). Also, a Fund’s investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds.
Growth Stocks Risk
Prices of growth stocks tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in a Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value. Expected growth may not be realized.

Prospectus 47/73

Small Cap Securities Risk (Alger Small Cap Growth Institutional Fund)
There may be greater risk investing in small capitalization companies rather than larger, more established companies owing to such factors as more limited product lines or financial resources or lack of management depth. They may be less financially secure than larger, more established companies. They may depend on a small number of key personnel. If a product fails or there are other adverse developments, or if management changes, a Fund’s investment in a small cap company may lose substantial value. In addition, it is more difficult to get information on smaller companies, which tend to be less well known, have shorter operating histories, do not have significant ownership by large investors and are followed by relatively few securities analysts. The securities of small cap companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger cap securities or the market as a whole. In addition, it may be difficult or impossible to liquidate a security position at a time and price acceptable to a Fund because of the potentially less frequent trading of stocks of smaller market capitalization. Small cap securities may be particularly sensitive to changes in interest rates, borrowing costs and earnings. Investing in small cap securities requires a longer term view.
Mid Cap Securities Risk (Alger Mid Cap Institutional Fund and Alger Small Cap Institutional Fund)
There may be greater risk in investing in medium-capitalization companies rather than larger, more established companies due to such factors as inexperienced management and limited product lines or financial resources. It may also be difficult or impossible to liquidate a security position at a time and price acceptable to the Fund because of the potentially less frequent trading of stocks of smaller market capitalization.
Foreign Securities Risk
Investing in foreign securities involves risks related to the political, social and economic conditions of foreign countries, particularly emerging market countries. These risks may include political instability, exchange control regulations, expropriation, lack of comprehensive information, national policies restricting foreign investment, currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing auditing, regulatory and legal standards and lack of accounting and financial reporting standards, inflation and rapid fluctuations in inflation, withholding or other taxes, and operational risks. There may be less stringent government supervision and oversight of foreign markets than in the United States. There may be less corporate financial information publicly available, less stringent investor protection and disclosure standards, and differing auditing and legal standards.
Investment in foreign currencies is subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedged positions, that the U.S. dollar will decline relative to the currency being hedged. Currency rates in foreign countries may fluctuate significantly over short periods of time. A decline in the value of foreign currencies relative to the U.S. dollar will reduce the value of securities held by a Fund and denominated in those currencies. Foreign currencies also are subject to risks caused by inflation, interest rates, budget deficits and low savings rates, political factors and government controls.
Sector Risk
Each Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make a Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly a Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility.
Technology Companies Risk – A Fund may be more susceptible to particular risks that may affect companies in the information technology sector and technology-related sectors than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole. Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of technology related companies’ securities may fall or fail to rise. Many technology related companies’ securities have historically been more volatile than other securities, especially over the short term.
Consumer Discretionary Sector Risk – The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.
Healthcare Companies Risk – A Fund may be more susceptible to particular risks that may affect companies in the healthcare

Prospectus 48/73

sector than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole, and the performance of such companies may be more volatile. The healthcare field is subject to substantial governmental regulation and may, therefore, be adversely affected by changes in governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of healthcare companies’ securities may fall or fail to rise. In addition, companies in the healthcare sector can be significantly affected by intense competition, aggressive pricing, technological innovations, product obsolescence, patent considerations, product compatibility and consumer preferences.
Communications Services Sector Risk – Communication services companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.
Industrial Companies Risk – A Fund may have a significant portion of its assets invested in securities of companies in the industrial sector. Industrial companies are affected by supply and demand both for their specific product or service and for industrial sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrial sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services.
Small Number of Holdings Risk (Alger Focus Equity Fund)
A Fund’s performance may be more vulnerable to changes in the market value of a single issuer and more susceptible to risks associated with a single economic, political, or regulatory occurrence than a fund that has a higher number of holdings. At times, the performance of shares of particular companies will lag the performance of other sectors or the market as a whole. This risk is magnified when a fund has a small number of holdings. Generally, the more broadly a fund invests, the more it spreads its risks and potentially reduces the risk of loss and volatility.
Portfolio Turnover (Active Trading) Risk (Alger Focus Equity Fund and Alger Mid Cap Growth Institutional Fund)
If a Fund engages in active trading of portfolio securities, it may incur increased transaction costs and brokerage commissions, both of which can lower the actual return on an investment. Active trading may also increase short-term gains and losses, which may affect the taxes a shareholder has to pay.
Cash Position Risk (Alger Small Cap Growth Institutional Fund)
A Fund may hold a portion of its assets in cash (or cash equivalents) at any time or for an extended time and may hold a significant portion of its assets in cash (or cash equivalents) when taking a temporary defensive position, as described under “Temporary Defensive Investments.” The Manager will determine the amount of a Fund’s assets to be held in cash (or cash equivalents) at its sole discretion, based on such factors as it may consider appropriate under the circumstances. To the extent a Fund holds assets in cash and otherwise uninvested, the ability of a Fund to meet its objective may be limited. If a Fund holds a large cash position, a Fund may under-perform relative to equity securities.
Temporary Defensive Investments
In times of adverse or unstable market, economic or political conditions, each Fund may invest up to 100% of its assets in cash, high-grade bonds, or cash equivalents (such as commercial paper or money market instruments) for temporary defensive reasons. This is to attempt to protect the Fund’s assets from a temporary, unacceptable risk of loss, rather than directly to promote the Fund’s investment objective. A Fund may also hold these types of securities in an amount up to 15% of net assets, pending the investment of proceeds from the sale of Fund shares or portfolio securities or to meet anticipated redemptions of Fund shares. A Fund may not achieve its investment objective while in a temporary defensive position.

The limitations do not apply to acquired fund fees and expenses, dividend expense on short sales, borrowing costs, interest, taxes, brokerage and extraordinary expenses, to the extent applicable. Each agreement runs through February 29, 2024 and may only be amended or terminated prior to its expiration date by agreement between the Manager and the Board, and will terminate automatically in the event of termination of the Investment Advisory Agreement. Such waiver/reimbursement arrangements are as follows: Alger Capital Appreciation Institutional Fund Class Y Shares – 0.75%; Alger Capital Appreciation Institutional Fund Class Z-2 Shares – 0.85%; Alger Focus Equity Fund Class Y Shares – 0.58%; Alger Focus Equity Fund Class Z Shares – 0.63%; Alger Mid Cap Growth Institutional Fund Class Z-2 Shares – 0.99%; and Alger Small Cap Growth Institutional Fund Class Z-2 Shares – 0.99%. The Manager may, during the term of the contract, recoup any fees waived or expenses reimbursed pursuant to the contract; however, a Fund will only make repayments to the Manager if such repayment does not cause a Fund’s expense ratio after the repayment is taken into account, to exceed both (i) the expense cap in place at the time such amounts were waived or reimbursed, and (ii) a Fund’s current expense cap. Such recoupment is limited to two years from the date the amount is initially waived or reimbursed.

Net Asset Value
The value of one share is its net asset value, or “NAV.” Each Fund values its financial instruments at fair value using independent dealers or pricing services under policies approved by the Board. Investments held by a Fund are valued on each day the New York Stock Exchange (the “NYSE”) is open, as of the close of the NYSE (normally 4:00 p.m. Eastern Time).
NAV of a class of shares is computed by adding together the value allocable to the class of a Fund’s investments plus cash and other assets, subtracting applicable liabilities and then dividing the result by the number of outstanding shares of the class.
Investments in money market funds and short-term securities held by a Fund having a remaining maturity of sixty days or less are valued at amortized cost which approximates market value.
Equity securities, including traded rights, warrants and option contracts for which valuation information is readily available, are valued at the last quoted sales price or official closing price on the primary market or exchange on which they are traded as reported by an independent pricing service. In the absence of quoted sales, such securities are valued at the bid price or, in the absence of a recent bid price, the equivalent as obtained from one or more of the major market makers for the securities to be valued.
Foreign securities are usually valued on the basis of the most recent closing price of the foreign markets on which such securities principally trade. Securities in which a Fund may invest may be traded in foreign markets that close before the close of the NYSE. Developments that occur between the close of the foreign markets and the close of the NYSE may result in adjustments to the closing foreign prices to reflect what the Manager, pursuant to policies established by the Board, believes to be the fair value of these securities as of the close of the NYSE. A Fund may also fair value securities in other situations, for example, when a particular foreign market is closed but a Fund is open.
Securities for which market quotations are not readily available are valued at fair value, as determined in good faith pursuant to procedures established by the Board.
Each Fund’s valuation techniques are generally consistent with either the market or the income approach to fair value. The market approach considers prices and other relevant information generated by market transactions involving identical or comparable assets to measure fair value. The income approach converts future amounts to a current, or discounted, single amount. These fair value measurements are determined on the basis of the value indicated by current market expectations about such future events. Because of the inherent uncertainty and often limited markets for restricted securities, the valuations assigned to such securities by a Fund may significantly differ from the valuations that would have been assigned by the Fund had there been an active market for such securities.
Valuation processes are determined by a valuation committee (the “Valuation Committee”) authorized by the Board and comprised of representatives of the Manager and officers of the Trust. The Valuation Committee reports its fair valuation determinations and related valuation information to the Board. The Board is responsible for approving the valuation policy and procedures. While the meetings are held on an as-needed basis, the Valuation Committee generally meets quarterly to review and evaluate the effectiveness of the procedures for making fair value determinations. The Valuation Committee considers, among other things, the results of quarterly back testing of the fair value model for foreign securities, pricing comparisons between primary and secondary price sources, the outcome of price challenges put to each Fund’s pricing vendor, and variances between transactional prices and the previous day’s price.

Purchasing and Redeeming Fund Shares
Shares of a Fund can be purchased or redeemed on any day the NYSE is open. Orders will be processed at the NAV next calculated after the purchase or redemption request is received in good order by the Transfer Agent or other agent appointed by the Distributor. Ordinarily, the Fund will issue a redemption check within seven days after the Transfer Agent receives a redemption request in good order. “In good order” means that all necessary information and documentation related to the redemption request have been provided to the Fund’s transfer agent or authorized intermediary, if applicable. If your request is not in good order, the Fund’s transfer agent may require additional documentation in order to redeem your shares. Payment may be postponed in cases where the SEC declares an emergency or normal trading is halted. The Transfer Agent or the Fund may reject any purchase order. Share certificates are not issued for shares of the Fund.
Under normal circumstances, each Fund expects to meet redemption requests by using cash or cash equivalents in its portfolio and/or by selling portfolio assets to generate cash. A Fund also may pay redemption proceeds using cash obtained through borrowing arrangements that may be available from time to time.
Each Fund may pay all or a portion of your redemption proceeds in securities rather than cash (i.e., “redeem in kind”) if, for example, the redemption request is during stressed market conditions or the Fund believes that a cash redemption may have a substantial impact on the Fund and its remaining shareholders. Securities will generally be selected on a pro rata basis pursuant to the Fund’s procedures. A shareholder who receives a redemption in kind bears the market risk of the securities until they are converted into cash, in transactions conducted at the shareholder’s expense.
Legislation passed by Congress in 2008 requires mutual funds to report both to the shareholder and to the Internal Revenue Service the “cost basis” of shares acquired on or after January 1, 2012 that are subsequently redeemed or exchanged. This reporting is not required for Fund shares held in retirement or other tax-advantaged accounts or for certain other types of entities (such as C corporations).
If you are a direct shareholder, you may request your cost basis reported on Form 1099-B to be calculated using any one of the alternative methods offered by the Fund. Please contact the Fund to make, revoke, or change your election. If you do not affirmatively elect a cost basis method then the Fund will use the average cost basis method. If you hold Fund shares through a broker, please contact that broker with respect to the reporting of cost basis and available elections for your account.
Please note that you will continue to be responsible for calculating and reporting gains and losses on redemptions of shares purchased prior to January 1, 2012. You are encouraged to consult your tax advisor regarding the application of the cost basis reporting rules and, in particular, which cost basis calculation method is best for you.

All Funds declare and pay dividends and distributions annually, and expect these payments to shareholders will consist primarily of capital gains, which may be taxable to you at different rates depending upon how long the Fund held the securities that it sold to create the gains (rather than the length of time you have held shares of the Fund), and that they will also include net investment income, which is taxable as ordinary income. Certain dividend income received by a Fund and paid to you may be subject to a maximum tax rate of 20% (qualified dividends); other income paid to you, such as non-qualifying dividend income or interest earned on debt securities held by the Fund, will continue to be taxed at the higher ordinary income rates. Shareholders who hold Fund shares in tax-deferred accounts ordinarily will not be subject to taxation on dividends from net investment income and net realized capital gains until they receive a distribution of the dividends from their individual plan accounts. Dividends and distributions may differ among classes of shares of a Fund. Unless your investment is in a tax-deferred account, you may want to avoid buying shares shortly before a Fund pays a dividend. If you buy shares when a Fund has declared, but not yet distributed ordinary income or capital gains, you will pay full price for the shares and then receive a portion of the price back in the form of a taxable dividend. In addition, it may be the case that a significant amount of the securities held by a Fund are held at values above their purchase price. In such cases, the sale of such securities in a Fund, which may be from a portfolio management decision or to meet Fund shareholder redemptions, will generate either long-term or short-term capital gains, which will be distributed and taxable to you as described above if your investment is not in a tax-deferred account. Therefore, a substantial tax liability may arise for a shareholder who invests in a Fund when such conditions exist. The amount of long-term and short-term capital gains are disclosed in a Fund’s most recent annual or semi-annual report. Before investing you may want to consult your tax advisor.
Unless you choose to receive cash payments by checking the box on your account application, any dividends and distributions will be reinvested automatically at the NAV on their payment dates. No sales charge will apply to automatically reinvested dividends and distributions. If you have chosen cash payments and a payment is returned to the Fund as undeliverable, that payment will be reinvested upon receipt by the Transfer Agent in Fund shares at the next NAV. All subsequent payments will be reinvested until you reinstate your cash election and provide a valid mailing address.
Regardless of whether you choose to take distributions in cash or reinvest them in a Fund, they may be subject to federal and state taxes. An exchange of Fund shares for shares of another fund will be treated as a sale of the Fund shares, and any gain on the

Prospectus 53/73

transaction may be subject to federal and state taxes. Because everyone’s tax situation is unique, see a tax advisor about federal, state and local tax consequences of investing in a Fund.

Investors should contact their Financial Intermediaries directly in order to purchase or redeem Fund shares.
Class I Shares
Class I Shares are generally available to institutional investors, such as corporations, foundations, and trusts managing various types of employee benefit plans, as well as charitable, religious and educational institutions. Class I shares are not subject to a minimum initial investment. Typical institutional investors include banks, insurance companies, broker-dealers, investment advisers, investment companies, qualified pension and profit-sharing plans, non-qualified deferred compensation plans, trusts funding charitable, religious and educational institutions and investors who invest through such institutions (or through an organization that processes investor orders on behalf of such institutions) and do so by paying a management, consulting or other fee to such institutions for the right to invest.
Pursuant to a shareholder servicing agreement adopted by the Trust, Class I Shares pay to the Distributor a shareholder servicing fee of 0.25% of the average daily net assets allocable to the Class I Shares of the Fund. The shareholder servicing fee may be used to pay for ongoing service and maintenance of shareholder accounts, administrative and shareholder services, and recordkeeping.
Class R Shares
Class R Shares are available to retirement and benefit plans and other institutional investors which place orders through financial intermediaries that perform administrative and/or other services for these accounts and that have entered into special arrangements with the Funds and/or the Distributor specifically for such orders. Class R Shares are generally not available to retail, traditional, simple and Roth IRAs, Coverdell Educational Savings, SEPs, SAR SEPs, and individual 403(b) and individual 529 tuition accounts.
Pursuant to a distribution plan adopted in accordance with Rule 12b-1 under the 1940 Act, Class R Shares pay the Distributor a distribution (12b-1) fee of 0.50% of the average net assets of the of the Fund allocable to the Class R Shares. The distribution fee may be used to pay for activities which primarily are intended to result in the sale of Class R Shares, as well as for servicing and maintenance of shareholder accounts.
In addition, pursuant to a shareholder servicing agreement adopted by the Trust, Class R Shares pay to the Distributor a shareholder servicing fee of 0.25% of the average daily net assets allocable to the Class R Shares of the Fund. The shareholder servicing fee may be used to pay for ongoing service and maintenance of shareholder accounts, administrative and shareholder services, and recordkeeping.
Class Y Shares
Class Y Shares are generally available for purchase by institutional investors such as qualified and non-qualified retirement, deferred compensation, and benefit plans, bank and trust companies, insurance companies, corporations, charitable organizations, endowments and foundations, government entities, and fund-of-funds. Class Y Shares are generally subject to a minimum initial investment and a minimum account size requirement of $500,000. Class Y Shares have no distribution and/or shareholder servicing (12b-1) fees. No remuneration is paid by Class Y Shares to financial intermediaries.

Exchanges
You can exchange shares of a Fund for shares of another fund in the Alger Family of Funds, subject to certain restrictions. Shares of the funds in the Alger Family of Funds can be exchanged or redeemed via telephone under certain circumstances. You should contact your Financial Intermediary to determine if you are able to exchange or redeem shares of the funds in the Alger Family of Funds via telephone. The Funds and Transfer Agent have reasonable procedures in place to determine that telephone instructions are genuine. They include requesting personal identification and recording calls. If the Funds and Transfer Agent follow these procedures, they are not liable for acting in good faith on telephone instructions. For more information on telephone exchanges and redemptions, contact the Transfer Agent.
Other Purchase and Exchange Limitations
If you are a participant in a retirement plan, such as a 401(k) plan, and you purchase shares in the Funds through an administrator or trustee that maintains a master or “omnibus” account with one or more Funds for trading on behalf of retirement plans and their participants, the Administrator may apply purchase and exchange limitations which are different than the limitations discussed herein. These limitations may be more or less restrictive than the limitations imposed by the Funds. Consult with your Administrator to determine what purchase and exchange limitations may be applicable to your transactions in the Funds through your retirement plan.
Limitations on Excessive Trading
Each of the Funds invests predominantly in U.S.-traded, highly liquid securities for which current New York Stock Exchange closing prices are readily available on a daily basis. Each Fund will determine a fair value for portfolio securities for which current market closing prices are not readily available or otherwise require fair valuation in the circumstances discussed under “Net Asset Value.” As a result, the Manager believes that there is little incentive for investors to engage in frequent and/or short-term trading (often referred to as market-timing) to benefit from “stale” pricing. Nonetheless, the presence of small capitalization and medium capitalization securities and/or foreign securities in a Fund and other circumstances may invite frequent and/or short-term trading by Fund shareholders, for whatever reason implemented. Active trading may be attempted and may, if carried out on a large scale, impose burdens on a Fund’s portfolio managers, interfere with the efficient management of a Fund, increase a Fund’s transaction costs, administrative costs or tax liability or otherwise be detrimental to the interests of a Fund and its other shareholders. The Funds therefore discourage market timing, and to the extent possible monitor for market timing patterns.
The Board has adopted policies and procedures to discourage frequent and/or short-term trading of Fund shares and will generally not accommodate such practices. These policies and procedures allow a Fund to reject purchase or exchange orders, on a temporary or permanent basis, or redeem all Fund shares from investors that the Manager believes, in its reasonable business judgment, are engaging in frequent and/or short-term trading in Fund shares or shares of other funds sponsored by the Manager that is detrimental to the Fund involved. If a Fund rejects your purchase or exchange order, you will not be able to execute that transaction, and neither the Fund nor the Manager will be responsible for any losses you may suffer as a result.
In order to detect significant market timing, the Manager, in accordance with policies and procedures approved by the Board, will, among other things, seek to monitor overall subscription, redemption and exchange activity, and isolate significant daily activity to determine if there appears to be market timing activity in an individual portfolio.

Prospectus 56/73

Under these policies and procedures, each Fund generally prohibits more than two purchases and sales or exchanges of its shares within a 90-day calendar period. The following transactions are excluded when determining whether trading activity is excessive: (i) transactions associated with systematic investment and withdrawal plans; (ii) transactions through firm-sponsored, discretionary asset allocation or wrap programs; and (iii) transactions subject to the trading policy of an intermediary that a Fund deems materially similar to the Fund’s policy. 
If, based on a Fund’s policies and procedures, the Manager determines that a shareholder is engaged in, or has engaged in, market timing or excessive trading, the Manager, on behalf of the Fund, may place a temporary or permanent block on all further purchases or exchanges of Fund shares.  Multiple accounts under common ownership or control may be considered one account for the purpose of determining a pattern of excessive trading, short-term market timing or other abusive trading practices.  A Fund will also utilize fair value pricing in an effort to reduce arbitrage opportunities available to short-term traders.
Due to the complexity involved in identifying excessive trading and market timing activity, there can be no guarantee that a Fund will be able to identify and restrict such activity in all cases.  Additionally, it is more difficult for a Fund to monitor the trading activity of beneficial owners of Fund shares who hold those shares through third-party 401(k) and other group retirement plans and other omnibus arrangements maintained by broker/dealers and other intermediaries.  Omnibus account arrangements permit multiple investors to aggregate their respective share ownership positions and purchase, redeem and exchange Fund shares in a single account. 
In certain circumstances a Fund may accept frequent trading restrictions of intermediaries that differ from the Fund’s policies and procedures. Such frequent trading restrictions of intermediaries may be more or less restrictive than a Fund’s policies and procedures. Since such intermediaries execute or administer transactions with many fund families, it may be impractical for them to enforce a particular fund’s frequent trading or exchange policy. These alternate trading restrictions would be authorized only if a Fund believes that the alternate restrictions would provide reasonable protection to the Fund and its shareholders; however a Fund does not monitor intermediaries’ frequent trading restrictions.  A Fund reserves the right to prohibit any purchase, sale or exchange of its shares that the Fund believes may be disruptive to the Fund or its long-term investors.
Disclosure of Portfolio Holdings
For a discussion of each Fund’s policies and procedures regarding the selective disclosure of its portfolio holdings, please see the SAI. Each Fund makes publicly available its month-end top 10 holdings with a 10 day lag and its month-end full portfolio with a 60 day lag on its website www.alger.com.
Other Information
In Kind Redemptions. A Fund may redeem some of your shares “in kind,” which means that some of the proceeds will be paid with securities the Fund owns instead of cash. The Fund has elected to be governed by rule 18f-1 under the 1940 Act, pursuant to which the Fund is obligated to redeem shares solely in cash up to the lesser of $250,000 or 1% of the net assets of the Fund during any 90-day period for any one shareholder. If you receive securities, you should expect to incur brokerage or other charges in converting the securities to cash. If a Fund pays large redemptions in cash, these transactions may increase the Fund’s transaction costs and detract from the Fund’s performance. Large purchases pose similar risks.
Shares may be worth more or less when you redeem them than they were at the time you bought them. For tax purposes, this means that when you redeem them you may realize a short- or long-term capital gain or loss, depending upon how long you have held the shares.
If you are a participant in a retirement plan, such as a 401(k) plan, and you purchase shares in a Fund through an administrator or trustee (“Plan Administrator”) that maintains a master or “omnibus” account with one or more funds for trading on behalf of retirement plans and their participants, the Plan Administrator may apply purchase and exchange limitations which are different than the limitations discussed herein. These limitations may be more or less restrictive than the limitations imposed by the Funds. Consult with your Plan Administrator to determine what purchase and exchange limitations may be applicable to your transactions in the Funds through your retirement plan.
Other Payments by the Funds. Certain Financial Intermediaries perform networking, sub-transfer agency, sub-accounting, recordkeeping and/or administrative services for their clients that would otherwise be performed by the transfer agent, UMB Fund Services, Inc. (the “Transfer Agent”). In addition to fees that the Funds may pay to a Financial Intermediary for distribution (12b-1) and shareholder servicing, and fees the Funds pay to the Transfer Agent, the Distributor, on behalf of a Fund, may enter into agreements with Financial Intermediaries pursuant to which a Fund will pay a Financial Intermediary for such services. These payments are generally based on either (1) a percentage of the average daily net assets of Fund shareholders serviced by a Financial Intermediary or (2) a fixed dollar amount for each account serviced by a Financial Intermediary. The aggregate amount of these payments may be substantial.
The Distributor may pay partnership and/or sponsorship fees to support seminars, conferences, and other programs designed to educate intermediaries about a Fund and may cover the expenses associated with attendance at such meetings, including travel

Prospectus 57/73

costs. The Distributor also may pay fees related to obtaining data regarding Financial Intermediary or financial advisor activities to assist the Distributor with sales reporting, business intelligence, and training and education opportunities. These payments and activities are intended to provide an incentive to Financial Intermediaries to sell a Fund by educating them about a Fund and helping defray the costs associated with offering a Fund. These payments may create a conflict of interest by influencing the Financial Intermediary to recommend a Fund over another investment. Ask your salesperson or visit your Financial Intermediary’s website for more information. The amount of any payments described by this paragraph is determined by the Manager or the Distributor, and all such amounts are paid out of their available assets, and not paid by you or a Fund. As a result, the total expense ratio of a Fund will not be affected by any such payments.
The Distributor does not pay any fees to Financial Intermediaries on Class Y shares.
Additional Compensation. From time to time the Distributor, at its expense from its own resources, may compensate Financial Intermediaries who are instrumental in effecting investments by their clients or customers in a Fund, in an amount up to 1% of the value of those investments. The Distributor may also from time to time, at its expense from its own resources, make payments to Financial Intermediaries that provide shareholder servicing, or transaction processing, with such payments structured as a percentage of gross sales, a percentage of net assets, and/or as a fixed dollar amount (the latter as a per account fee or as reimbursement for transactions processing and transmission charges). The Distributor determines whether to make any additional cash payments and the amount of any such payments in response to requests from Financial Intermediaries, based on factors the Distributor deems relevant. Factors considered by the Distributor generally include the Financial Intermediary’s reputation, ability to attract and retain assets for the Fund, expertise in distributing a particular class of shares of the Fund, entry into target markets, and/or quality of service. In addition, the Distributor may make payments to dealer firms in the form of payments for marketing support, seminar support, training meetings, or comparable expenses in the discretion of the Distributor. Please contact your Financial Intermediary for details about revenue sharing payments it may receive. Any payments described above will not change the price paid by investors for the purchase of shares of a Fund or the amount of proceeds received by a Fund on the sale of shares.
Redemptions by the Funds. If your account, excluding asset-based fee program accounts and accounts held with certain intermediaries, falls below the minimum initial investment amount of the share class in which you are invested, a Fund may redeem all the Fund shares within your account after giving you 60 days’ prior written notice. You may avoid having your account redeemed during the notice period by bringing the account value up to the minimum initial investment amount.
The Funds and their agents reserve the right at any time to reject or cancel all or any part of any purchase or exchange order and to redeem all Fund shares if it suspects the shareholder is engaged in, or has engaged in, abusive trading practices and/or violations of any applicable securities laws. When an exchange request in respect of Fund shares is rejected, such shares may be redeemed from the Fund on request of the shareholder. In addition, the Fund reserves the right to modify any terms or conditions of purchase of shares of the Fund or suspend, change or withdraw all or any part of the offering made by this prospectus. If the Fund rejects your purchase or exchange order, you may not be able to execute that transaction, and the Funds and their agents will not be responsible for any losses you may suffer as a result.
Lost Shareholders, Inactive Accounts and Unclaimed Property. It is important that each Fund maintain a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned to a Fund. Based upon statutory requirements for returned mail, the Fund will attempt to locate the shareholder or rightful owner of the account. If the Fund is unable to locate the shareholder, then it will determine whether the shareholder’s account would legally be considered abandoned. Your mutual fund account may be transferred to the state government of your state of residence if no shareholder initiated activity occurs within your account during the “inactivity period” specified in your state’s abandoned property laws. Each Fund is legally obligated to escheat (or transfer) abandoned property to the appropriate state’s unclaimed property administrator in accordance with statutory requirements. The shareholder’s last known address of record determines which state has jurisdiction. If you hold your account directly at the Transfer Agent, please proactively contact the Transfer Agent toll-free at (800) 992-3863 at least annually to ensure your account remains in active status. You may also update your contact information through your Alger access account online at www.alger.com.
If you are a resident of the state of Texas, you may designate a representative to receive notifications that, due to inactivity, your mutual fund account assets may be delivered to the Texas Comptroller. Please contact the Transfer Agent if you wish to complete a Texas Designation of Representative form.
Householding. To reduce expenses, only one copy of most financial reports and prospectuses may be mailed to households, even if more than one person in a household holds shares of a Fund. Call an Alger Funds Representative at (800) 992-3863 if you need additional copies of financial reports or prospectuses, or download them at www.alger.com. If you do not want the mailing of these documents to be combined with those for other members of your household, contact The Alger Funds in writing at Alger Family of Funds, c/o UMB Fund Services, Inc., P.O. Box 2175, Milwaukee, WI  53212-2175.

Hypothetical Investment and Expense Information
Hypothetical investment and expense information, which is not required to be included in this Prospectus by the SEC, is presented in the chart below. This information is intended to reflect the annual and cumulative effect of a Fund’s expenses, including advisory fees and other Fund costs, on each Fund’s total return based on NAV over a 10-year period. The example assumes the following:
You invest $10,000 in the Fund and hold it for the entire 10-year period; and
Your investment has a 5% return before expenses each year.
There is no assurance that the annual expense ratio will be the expense ratio for the Fund  classes for any of the years shown. To the extent that the Manager and any of its affiliates alter any fee waivers and/or expense reimbursements pursuant to a voluntary or contractual arrangement, your actual expenses may be higher or lower. This is only a hypothetical presentation made to illustrate what expenses and returns would be under the above scenarios. Your actual expenses and returns are likely to differ (higher or lower) from those shown below.

Financial Highlights
The financial highlights tables are intended to help you understand each Fund’s financial performance for the periods shown. Certain information reflects financial results for a single Fund share. The total returns in the tables represent the rate that an investor would have earned or lost on an investment in the Fund (assuming reinvestment of all dividends and distributions). The information in the tables for the fiscal years ended October 31 has been audited by Deloitte & Touche LLP, whose report, along with each Fund’s financial statements, is included in the Annual Report, which is available upon request.

The Prospectuses discuss the investment objectives of each series (each, a “Fund” and together, the “Funds”) of The Alger Institutional Funds (the “Trust”) and the principal investment strategies to be employed to achieve those objectives. The principal risks related to each Fund’s principal investment strategies are also noted in the Prospectuses. This section of the SAI contains supplemental information concerning all types of securities and other instruments in which a Fund may invest, the investment policies and portfolio strategies that a Fund may utilize (i.e., both principal and non-principal investment strategies) and certain risks attendant to those investments, policies and strategies (i.e., both principal and non-principal risks of investing in the Fund).
All of the Funds seek to achieve their objectives by investing in equity securities, such as common or preferred stocks, or securities convertible into or exchangeable for equity securities, including warrants and rights. The Funds will invest primarily in companies whose securities are traded on domestic stock exchanges or in the over-the-counter market. These companies may be in the developmental stage, may be older companies that appear to be entering a new stage of growth progress owing to factors such as management changes or development of new technology, products or markets, or may be companies providing products or services with a high unit-volume growth rate. In order to afford the Funds the flexibility to take advantage of new opportunities for investments in accordance with their investment objectives and to meet redemptions, they may hold up to 15% of their net assets in money market instruments and repurchase agreements and in excess of that amount (up to 100% of their assets) during temporary defensive periods, explained further below. This amount may be higher than that maintained by other funds with similar investment objectives.
The investment strategies of Fred Alger Management, LLC (“Alger Management” or the “Manager”) utilize the proprietary research of its analyst and portfolio management team to continually assess the markets and sectors it follows for attractive investment opportunities. With respect to stocks in the Funds’ portfolios, one principle of the portfolio strategy at Alger Management is for analysts and portfolio managers to evaluate the return potential vs. risk (downside) in each stock held in a portfolio and compare that to those, and other variables, offered by other stocks under coverage within Alger Management’s research team. Portfolio managers, together with investment analysts, at Alger Management continually seek to optimize performance of the Funds’ portfolios by replacing individual stocks, or reducing or increasing their relative weighting in other portfolios, with stocks evaluated as having better appreciation potential, having improved reward to risk opportunity, or offering the portfolio diversification or other characteristics determined to be beneficial to achieving the portfolio’s overall objectives. The Funds’ portfolio turnover rates may vary significantly from year to year as a result of the Funds’ investment process.
There is no guarantee that a Fund’s investment objective will be achieved.
The Funds will adjust their holdings as considered advisable in view of prevailing or anticipated market conditions, and turnover will not be a limiting factor should Alger Management deem it advisable to purchase or sell securities.
A Fund’s turnover rate is calculated by dividing the lesser of purchases or sales of securities for the fiscal year by the monthly average of the value of the Fund’s securities, with obligations with less than one year to maturity excluded.
Unforeseen Market Events
Unpredictable events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, recessions, or other events may significantly affect the economy and the markets and issuers in which a fund invests. Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets, while some events may affect certain geographic regions, countries, sectors, and industries more significantly than others and exacerbate other preexisting political, social, and economic risks. Since early 2020, a novel strain of coronavirus (COVID-19) has resulted in disruptions to global business activity and caused significant volatility and declines in global financial markets.
These types of events, such as the global pandemic caused by COVID-19, may also cause widespread fear and uncertainty and result in, among other things: enhanced health screenings, quarantines, cancellations, and travel restrictions, including border closings; disruptions to business operations, supply
3

chains and customer activity; exchange trading suspensions and closures, and overall reduced liquidity of securities, derivatives, and commodities trading markets; reductions in consumer demand and economic output; and significant challenges in healthcare service preparation and delivery. A Fund could be negatively impacted if the value of a portfolio holding were harmed by such political or economic conditions or events. In addition, the operations of a Fund, the Manager, and a Fund’s service providers may be significantly impacted, or even temporarily halted, as a result of any impairment to their information technology and other operational systems, extensive employee illnesses or unavailability, government quarantine measures, and restrictions on travel or meetings and other factors related to public emergencies. Governmental and quasi-governmental authorities and regulators have in the past responded to major economic disruptions with a variety of significant fiscal and monetary policy changes, including but not limited to, direct capital infusions into companies, new monetary programs, and dramatically lower interest rates. An unexpected or quick reversal of these policies, or the ineffectiveness of these policies, could negatively impact overall investor sentiment and further increase volatility in securities markets. The impact of this outbreak has adversely affected the economies of many nations and the entire global economy and may impact individual issuers and capital markets in ways that cannot be foreseen. Other infectious illness outbreaks that may arise in the future could have similar or other unforeseen effects. The duration of this outbreak or others and their effects cannot be determined with certainty.
In addition, global climate change may have an adverse effect on the value of securities and other assets. Economists and others have expressed increasing concern about the potential effects of global climate change on property and security values. Impacts from climate change may include significant risks to global financial assets and economic growth. Certain issuers, industries and regions may be adversely affected by the impacts of climate change, including on the demand for and the development of goods and services and related production costs, and the impacts of legislation, regulation and international accords related to climate change, as well as any indirect consequences of regulation or business trends driven by climate change.
Common and Preferred Stocks
Stocks represent shares of ownership in a company. Generally, preferred stock has a specified dividend and ranks after bonds and before common stocks in its claim on income for dividend payments and on assets should the company be liquidated. After other claims are satisfied, common stockholders participate in company profits on a pro-rata basis; profits may be paid out in dividends or reinvested in the company to help it grow. Increases and decreases in earnings are usually reflected in a company’s stock price, so common stocks generally have the greatest appreciation and depreciation potential of all corporate securities. While most preferred stocks pay a dividend, each Fund may purchase preferred stock where the issuer has omitted, or is in danger of omitting, payment of its dividend. Such investments would be made primarily for their capital appreciation potential. Each Fund may purchase trust preferred securities which are preferred stocks issued by a special purpose trust subsidiary backed by subordinated debt of the corporate parent. These securities typically bear a market rate coupon comparable to interest rates available on debt of a similarly rated company. Holders of the trust preferred securities have limited voting rights to control the activities of the trust and no voting rights with respect to the parent company.
Temporary Defensive and Interim Investments
When market conditions are unstable, or the Manager believes it is otherwise appropriate to reduce holdings in stocks, the Funds can invest in a variety of debt securities for defensive purposes. The Funds can also purchase these securities for liquidity purposes to meet cash needs due to the redemption of Fund shares, or to hold while waiting to reinvest cash received from the sale of other portfolio securities. The Funds can buy:
high-quality, short-term money market instruments, including those issued by the U.S. Treasury or other government agencies;
commercial paper (short-term, unsecured, promissory notes of domestic or foreign companies);
short-term debt obligations of corporate issuers, certificates of deposit and bankers’ acceptances of domestic and foreign banks and savings and loan associations; and
repurchase agreements.
4

Short-term debt securities would normally be selected for defensive or cash management purposes because they can normally be disposed of quickly and are not generally subject to significant fluctuations in principal value, and their value will be less subject to interest rate fluctuation than longer-term debt securities.
Small Capitalization Investments
Certain companies in which a Fund will invest may still be in the developmental stage. Investing in smaller issuers generally involves greater risk than investing in larger, more established issuers. Such companies may have limited product lines, markets or financial resources and may lack management depth. Their securities may have limited marketability and may be subject to more abrupt or erratic market movements than securities of larger, more established companies or the market averages in general.
Bank Obligations
Bank obligations are certificates of deposit, bankers’ acceptances, and other short-term debt obligations. Certificates of deposit are short-term obligations of commercial banks. A bankers’ acceptance is a time draft drawn on a commercial bank by a borrower, usually in connection with international commercial transactions. Certificates of deposit may have fixed or variable rates.
The Funds will not invest in any debt security issued by a commercial bank unless (i) the bank has total assets of at least $1 billion, or the equivalent in other currencies, or, in the case of domestic banks that do not have total assets of at least $1 billion, the aggregate investment made in any one such bank is limited to $250,000 and the principal amount of such investment is insured in full by the Federal Deposit Insurance Corporation; and (ii) in the case of foreign banks, the security is, in the opinion of Alger Management, of an investment quality comparable to other debt securities which may be purchased by the Funds. These limitations do not prohibit investments in securities issued by foreign branches of U.S. banks, provided such U.S. banks meet the foregoing requirements.
Foreign Bank Obligations
Investments by the Funds in foreign bank obligations and obligations of foreign branches of domestic banks present certain risks, including the impact of future political and economic developments, the possible imposition of withholding taxes on interest income, the possible seizure or nationalization of foreign deposits, the possible establishment of exchange controls and/or the addition of other foreign governmental restrictions that might affect adversely the payment of principal and interest on these obligations. In addition, there may be less publicly available and reliable information about a foreign bank than about domestic banks owing to different accounting, auditing, reporting and record-keeping standards.
Short-Term Corporate Debt Securities
These are outstanding nonconvertible corporate debt securities (e.g., bonds and debentures) which have one year or less remaining to maturity. Corporate notes may have fixed, variable, or floating rates.
Commercial Paper
These are short-term promissory notes issued by corporations primarily to finance short-term credit needs.
Convertible Securities
Each Fund may invest in convertible securities, which are debt instruments or preferred stocks that make fixed dividend or interest payments  and are convertible into common stock. Generally, the market prices of convertible securities tend to reflect price changes in their underlying common stocks, but also tend to respond inversely to changes in interest rates. Convertible securities typically entail less market risk than investments in the common stock of the same issuers. Declines in their market prices are typically not as pronounced as those of their underlying common stocks. Like all fixed-income securities, convertible securities are subject to the risk of default on their issuers’ payment obligations.
Variable Rate Master Demand Notes
These are unsecured instruments that permit the indebtedness thereunder to vary and provide for periodic adjustments in the interest rate. Because these notes are direct lending arrangements between a Fund and an issuer, they are not normally traded. Although no active secondary market may exist for these notes, a Fund may demand payment of principal and accrued interest at any time or may resell the note to a third party. While the notes are not typically rated by credit rating agencies, issuers of variable
5

rate master demand notes must satisfy Alger Management that the same criteria for issuers of commercial paper are met. In addition, when purchasing variable rate master demand notes, Alger Management will consider the earning power, cash flows and other liquidity ratios of the issuers of the notes and will continuously monitor their financial status and ability to meet payment on demand. In the event an issuer of a variable rate master demand note were to default on its payment obligations, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default.
U.S. Government Obligations
Each Fund may invest in U.S. Government securities, which include Treasury Bills, Treasury Notes and Treasury Bonds that differ in their interest rates, maturities and times of issuance. Treasury Bills have initial maturities of one year or less; Treasury Notes have initial maturities of one to ten years; and Treasury Bonds generally have initial maturities of greater than ten years. In addition to U.S. Treasury securities, each Fund may invest in securities issued or guaranteed by the U.S. Government or its agencies or instrumentalities. Some obligations issued or guaranteed by U.S. Government agencies and instrumentalities are supported by the full faith and credit of the U.S. Treasury; others by the right of the issuer to borrow from the Treasury; others by discretionary authority of the U.S. Government to purchase certain obligations of the agency or instrumentality; and others only by the credit of the agency or instrumentality. These securities bear fixed, floating or variable rates of interest. While the U.S. Government currently provides financial support to such U.S. Government-sponsored agencies or instrumentalities, no assurance can be given that it will always do so, since it is not so obligated by law.
U.S. Government Agency Securities
U.S. government agency securities are issued or guaranteed by U.S. Government-sponsored enterprises and federal agencies. These include securities issued by the Federal National Mortgage Association, Government National Mortgage Association, Federal Home Loan Bank, Federal Land Bank, Farmers Home Administration, Bank for Cooperatives, Federal Intermediate Credit Bank, Federal Financing Bank, Federal Farm Credit System, the Small Business Administration, Federal Housing Administration, and Maritime Administration. Some of these securities are supported by the full faith and credit of the U.S. Treasury, and the remainder are supported only by the credit of the instrumentality, which may or may not include the right of the issuer to borrow from the Treasury.
Lending of Portfolio Securities
The Funds have the authority to lend securities to brokers, dealers and other financial organizations. The Funds will not lend securities to Alger Management or its affiliates. By lending its securities, a Fund can increase its income by continuing to receive interest or dividends on the loaned securities as well as by either investing the cash collateral in short-term securities or by earning income in the form of interest paid by the borrower when U.S. Government securities or letters of credit are used as collateral. Each Fund will adhere to the following conditions whenever its securities are loaned: (a) the Fund must receive at least 100% cash collateral or equivalent securities from the borrower; (b) the borrower must increase this collateral whenever the market value of the loaned securities including accrued interest exceeds the value of the collateral; (c) the Fund must be able to terminate the loan at any time; (d) the Fund must receive reasonable interest on the loan, as well as any dividends, interest or other distributions on the loaned securities and any increase in market value; (e) the Fund may pay only reasonable custodian fees in connection with the loan; and (f) voting rights on the loaned securities may pass to the borrower; provided, however, that if a material event adversely affecting the investment occurs, the Board of Trustees of the Trust (the “Board”) must terminate the loan and regain the right to vote the securities.
A Fund bears a risk of loss in the event that the other party to a securities loan transaction defaults on its obligations and the Fund is delayed in or prevented from exercising its rights to dispose of the collateral, including the risk of a possible decline in the value of the collateral securities during the period in which the Fund seeks to assert these rights, the risk of incurring expenses associated with asserting these rights and the risk of losing all or a part of the income from the transaction.
Repurchase Agreements
Each Fund may engage in repurchase agreement transactions with banks, registered broker-dealers and government securities dealers approved by the Board. Under the terms of a repurchase agreement, a Fund would acquire a high quality money market instrument for a relatively short period (usually not more than one week) subject to an obligation of the seller to repurchase, and the Fund to resell, the instrument at an agreed price (including accrued interest) and time, thereby determining the yield during
6

the Fund’s holding period. Repurchase agreements may be seen to be loans by the Fund collateralized by the underlying instrument. This arrangement results in a fixed rate of return that is not subject to market fluctuations during the Fund’s holding period and not necessarily related to the rate of return on the underlying instrument. The value of the underlying securities, including accrued interest, will be at least equal at all times to the total amount of the repurchase obligation, including interest. A Fund bears a risk of loss in the event that the other party to a repurchase agreement defaults on its obligations and the Fund is delayed in or prevented from exercising its rights to dispose of the collateral securities, including the risk of a possible decline in the value of the collateral securities during the period in which the Fund seeks to assert these rights, the risk of incurring expenses associated with asserting these rights and the risk of losing all or part of the income from the agreement. Alger Management reviews the creditworthiness of those banks, dealers and clearing corporations with which the Funds enter into repurchase agreements to evaluate these risks and monitors on an ongoing basis the value of the securities subject to repurchase agreements to ensure that the value is maintained at the required level.
Warrants and Rights
Each Fund may invest in warrants and rights. A warrant is a type of security that entitles the holder to buy a specified amount of common stock at a specified price, usually higher than the market price at the time of issuance, for a period of years or to perpetuity. In contrast, rights, which also represent the right to buy common shares, normally have a subscription price lower than the current market value of the common stock and a life of two to four weeks. Warrants are freely transferable and are traded on the major securities exchanges.
Restricted and Illiquid Securities
A Fund will not invest more than 15% of its net assets in “illiquid” investments, which are defined as securities that the Manager reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment.
Each Fund may invest in restricted securities; i.e., securities that are subject to legal or contractual restrictions on their resale. These restrictions might prevent the sale of the securities at a time when a sale would otherwise be desirable.
Each Fund may invest in restricted securities governed by Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). Rule 144A is designed to facilitate efficient trading of unregistered securities among institutional investors. Rule 144A permits the resale to qualified institutions of restricted securities that, when issued, were not of the same class as securities listed on a U.S. securities exchange or quoted on NASDAQ.
Restricted securities may be illiquid or less liquid. In determining the liquidity of a restricted security, the Manager will, using information obtained after reasonable inquiry, take into account relevant market, trading, and investment-specific considerations. If institutional trading in restricted securities were to decline to limited levels, the liquidity of a Fund could be adversely affected.
Short Sales
Each Fund may sell securities “short against the box.” While a short sale is the sale of a security the Fund does not own, it is “against the box” if at all times when the short position is open the Fund owns an equal amount of the securities or securities convertible into, or exchangeable without further consideration for, securities of the same issue as the securities sold short. Short sale transactions have been subject to increased regulatory scrutiny in response to recent market events, including the imposition of restrictions on short-selling certain securities and reporting requirements. Regulatory authorities may from time to time impose restrictions that adversely affect the ability to borrow certain securities in connection with short sale transactions. Regulations imposed by the SEC, and the potential for further interventions by the SEC or other regulators, may discourage or impede short selling practices due to the increased economic, regulatory, compliance and disclosure obligations or risks that they present.
Foreign Securities
Each Fund may invest up to 20% of the value of its total assets in foreign securities. Foreign securities are securities issued by companies generally defined by a third party, or in certain circumstances by a Portfolio Manager, (i) that are organized under the laws of a foreign country; (ii) whose securities are primarily listed in a foreign country; or (iii) that have a majority of their assets, or derive more than 50% of their revenue or profits from business, investments, or sales, outside the United States. Foreign
7

securities investments may be affected by changes in currency rates or exchange control regulations, changes in governmental administration or economic or monetary policy (in the United States and abroad) or changed circumstances in dealings between nations. Dividends paid by foreign issuers may be subject to withholding and other foreign taxes that may decrease the net return on these investments as compared to dividends paid to the Fund by domestic corporations. It should be noted that there may be less publicly available information about foreign issuers than about domestic issuers, and foreign issuers are not subject to uniform accounting, auditing and financial reporting standards and requirements comparable to those of domestic issuers. Securities of some foreign issuers are more volatile than securities of comparable domestic issuers and foreign brokerage commissions are generally higher than in the United States. Foreign securities markets may also be more volatile and less subject to government supervision than those in the United States. Investments in foreign countries could be affected by other factors not present in the United States, including expropriation, confiscatory taxation and potential difficulties in enforcing contractual obligations. Securities purchased on foreign exchanges may be held in custody by a foreign branch of a domestic bank.
Each Fund may invest in the securities of foreign issuers in the form of American Depositary Receipts and American Depositary Shares (collectively, “ADRs”) and Global Depositary Receipts and Global Depositary Shares (collectively, “GDRs”) and other forms of depositary receipts. These securities may not necessarily be denominated in the same currency as the securities into which they may be converted. ADRs are receipts typically issued by a United States bank or trust company which evidence ownership of underlying securities issued by a foreign corporation. GDRs are receipts issued outside the United States typically by non-United States banks and trust companies that evidence ownership of either foreign or domestic securities. Generally, ADRs in registered form are designed for use in the United States securities markets and GDRs in bearer form are designed for use outside the United States.
These securities will generally be purchased through “sponsored” facilities. A sponsored facility is established jointly by the issuer of the underlying security and a depositary. A depositary may establish an unsponsored facility without participation by the issuer of the deposited security. Holders of unsponsored depositary receipts generally bear all the costs of such facilities, and the depositary of an unsponsored facility frequently is under no obligation to distribute shareholder communications received from the issuer of the deposited security or to pass through voting rights to the holders of such receipts in respect of the deposited securities.
Executive Order on Securities Investments that Finance Communist Chinese Military Companies
As a result of an Executive Order issued by the former President of the United States (the “Order”), effective January 11, 2021, U.S. persons (including the Funds) are prohibited from transacting in certain securities and derivatives of publicly traded securities of any companies designated as a “Communist Chinese military company” (“CCMCs” and collectively with securities of certain subsidiaries of such companies and related depositary receipts that may be covered by the Order, “CCMC Securities”) by the U.S. Department of Defense (the “DOD”) or the U.S. Department of the Treasury’s Office of Foreign Assets Control (“OFAC”) unless such transactions are for purposes of divestment. The DOD designated an initial list of CCMCs prior to January 11, 2021 and, along with OFAC, may designate additional CCMCs from time to time. U.S. persons may divest their holdings in the initially-designated CCMCs at any time through November 11, 2021. With respect to additional CCMCs, U.S. persons will be prohibited from transacting in CCMC Securities 60 days after such CCMC is designated by the DOD or OFAC, and will have 365 days from such designation date to divest their holdings in those CCMC Securities.
OFAC subsequently published, on several occasions, guidance regarding compliance with the Order, including several “Frequently Asked Questions” (FAQs)-style publications addressing the scope of, and interpretive matters regarding, compliance with the Order, as well as the Order’s application to U.S. funds that hold CCMC Securities (i.e., including mutual funds that hold CCMC Securities regardless of the size of the position relative to a fund’s total assets). Certain interpretive issues related to compliance with the Order remain open, including to what extent a U.S. person could be held liable for failing to identify an unlisted entity whose name “close matches the name” of an entity designated as a Communist Chinese military company.
8

A Fund’s performance may be adversely impacted by restrictions on its ability to hold CCMC Securities. The extent of any impact will depend on future developments, including a Fund’s ability to buy and sell the CCMC Securities, valuation of the CCMC Securities, modifications to the Order, the issuance of additional or different interpretive guidance regarding compliance with the Order, and the duration of the Order, all of which are highly uncertain.
Investing in Europe
Ongoing concerns regarding the economies of certain European countries and/or their sovereign debt, as well as the possibility that one or more countries might leave the European Union (the “EU”), create risks for investing in the EU. A number of countries in Europe have experienced severe economic and financial difficulties. Many non-governmental issuers, and even certain governments, have defaulted on, or been forced to restructure, their debts. Many other issuers have faced difficulties obtaining credit or refinancing existing obligations. Financial institutions have in many cases required government or central bank support, have needed to raise capital, and/or have been impaired in their ability to extend credit, and financial markets in Europe and elsewhere have experienced significant volatility and declines in asset values and liquidity. These difficulties may continue, worsen or spread within and outside of Europe. Responses to the financial problems by European governments, central banks and others, including austerity measures and reforms, may not be effective, may result in social unrest and may limit future growth and economic recovery or have other unintended consequences. Further defaults or restructurings by governments and others of outstanding debt could have additional adverse effects on economies, financial markets and asset valuations around the world.
In June 2016, the United Kingdom (the “UK”) held a referendum resulting in a vote in favor of the exit of the UK from the EU (known as “Brexit”). On March 29, 2017, the UK triggered the withdrawal procedures in Article 50 of the Treaty of Lisbon which provides for a two-year negotiation period between the EU and the withdrawing member state. Pursuant to an agreement between the UK and the EU, the UK left the EU on January 31, 2020, subject to a transitional period ending December 31, 2020. The UK and the EU reached a trade and cooperation agreement on December 31, 2020, which went into effect on January 1, 2021.
Brexit is widely expected to have consequences that are both profound and uncertain for the economic and political future of the UK and the EU. The range and potential implications of possible political, regulatory, economic and market outcomes cannot be fully known at this time, but could be significant, potentially resulting in increased volatility and illiquidity and lower economic growth for companies that rely significantly on Europe for their business activities and revenues. The UK has one of the largest economies in Europe and is a major trading partner with the other EU countries and the United States. Brexit may create additional and substantial economic stresses for the UK, including a contraction of the UK’s economy, decreased trade, capital outflows, devaluation of the British pound, as well as a decrease in business and consumer spending and investment. The negative impact on not only the UK and other European economies but also the broader global economy could be significant. Due to the very recent occurrence of these events, the full scope and nature of the consequences are not at this time known and are unlikely to be known for a significant period of time.
It is not possible to ascertain the precise impact these events may have on a Fund or its investments from an economic, financial, tax or regulatory perspective but any such impact could have material consequences for a Fund and its investments. Whether or not a Fund invests in securities of issuers located in Europe or has significant exposure to European issuers or countries, these events could negatively affect the value and liquidity of a Fund’s investment.
Emerging Markets Investments
A Fund may invest in the securities of issuers domiciled in various countries with emerging capital markets. Unless otherwise provided in a Fund’s Prospectuses, a country with an emerging capital market is any country that is (i) generally recognized to be an emerging market country by the international financial community, such as the International Finance Corporation, or determined by the World Bank to have a low, middle or middle upper income economy; (ii) classified by the United Nations or its authorities to be developing; and/or (iii) included in a broad-based index that is generally representative of emerging markets. Countries with emerging markets can be found in regions such as Asia, Latin America, Eastern Europe and Africa.
9

Investments in the securities of issuers domiciled in countries with emerging capital markets involve certain additional risks that do not generally apply to investments in securities of issuers in more developed capital markets, such as (i) low or non-existent trading volume, resulting in market illiquidity and increased volatility in prices for such securities, as compared to securities of comparable issuers in more developed capital markets; (ii) uncertain national policies and social, political and economic instability, increasing the potential for expropriation of assets, confiscatory taxation, high rates of inflation or unfavorable diplomatic developments; (iii) possible fluctuations in exchange rates, differing legal systems and the existence or possible imposition of exchange controls, custodial restrictions or other foreign or U.S. governmental laws or restrictions applicable to such investments; (iv) national policies that may limit a Fund’s investment opportunities such as restrictions on investment in issuers or industries deemed sensitive to national interests; and (v) the lack or relatively early development of legal structures governing private and foreign investments and private property. In addition to withholding taxes on investment income, some countries with emerging markets may impose differential capital gains taxes on foreign investors.
Political and economic structures in emerging market countries may be undergoing significant evolution and rapid development, and these countries may lack the social, political and economic stability characteristic of more developed countries. In such a dynamic environment, there can be no assurance that any or all of these capital markets will continue to present viable investment opportunities for a Fund. In the past, governments of such nations have expropriated substantial amounts of private property, and most claims of the property owners have never been fully settled. There is no assurance that such expropriations will not reoccur. In such an event, it is possible that a Fund could lose the entire value of its investments in the affected market. As a result the risks described above, including the risks of nationalization or expropriation of assets, may be heightened. In addition, unanticipated political or social developments may affect the value of investments in these countries and the availability to a Fund of additional investments. The small size and inexperience of the securities markets in certain of these countries and the limited volume of trading in securities in these countries may make investments in the countries illiquid and more volatile than investments in Japan or most Western European countries.
Also, there may be less publicly available information about issuers in emerging markets than would be available about issuers in more developed capital markets, and such issuers may not be subject to accounting, auditing and financial reporting standards and requirements comparable to those to which U.S. companies are subject. In certain countries with emerging capital markets, reporting standards vary widely. As a result, traditional investment measurements used in the United States, such as price/earnings ratios, may not be applicable. Emerging market securities may be substantially less liquid than, and more volatile than, those of mature markets, and company shares may be held by a limited number of persons. This may adversely affect the timing and pricing of a Fund’s acquisition or disposal of securities.
Practices in relation to settlement of securities transactions in emerging markets involve higher risks than those in developed markets, in part because a Fund will need to use brokers and counterparties that are less well capitalized, and custody and registration of assets in some countries may be unreliable. The possibility of fraud, negligence, undue influence being exerted by the issuer or refusal to recognize ownership exists in some emerging markets, and, along with other factors, could result in ownership registration being completely lost. A Fund would absorb any loss resulting from such registration problems and may have no successful claim for compensation.
In addition, some emerging markets countries may have fixed or managed currencies which are not free-floating against the U.S. dollar. Further, certain emerging markets countries’ currencies may not be internationally traded. Certain of these currencies have experienced volatility relative to the U.S. dollar. If a Fund does not hedge the U.S. dollar value of securities it owns denominated in currencies that are devalued, the Fund’s net asset value will be adversely affected. If a Fund hedges the U.S. dollar value of securities it owns denominated in currencies that increase in value, the Fund will not benefit from the hedge it purchased, and will lose the amount it paid for the hedge. Many emerging markets countries have experienced substantial, and in some periods extremely high, rates of inflation for many years. Inflation and rapid fluctuations in inflation rates have had and may continue to have adverse effects on the economies and securities markets of certain of these countries.
10

Derivative Transactions
Each Fund may invest in, or enter into, derivatives for a variety of reasons, including to hedge certain market or interest rate risks, to provide a substitute for purchasing or selling particular securities or to increase potential returns. Generally, derivatives are financial contracts whose value depends upon, or is derived from, the value of an underlying asset, reference rate or index, and may relate to stocks, bonds, interest rates, currencies or currency exchange rates, and related indexes. Examples of derivative instruments the Funds may use include, but are not limited to options contracts, futures contracts, and options on futures contracts. Derivatives may provide a cheaper, quicker or more specifically focused way for a Fund to invest than “traditional” securities would. Alger Management, however, may decide not to employ some or all of these strategies for a Fund and there is no assurance that any derivatives strategy used by a Fund will succeed. The SEC recently adopted Rule 18f-4 under the Investment Company Act of 1940, as amended (the “1940 Act”), which will regulate the use of derivatives for certain funds registered under the 1940 Act. Unless a Fund qualifies as a “limited derivatives user” as defined in Rule 18f-4, the rule would, among other things, require the Fund to establish a comprehensive derivatives risk management program, to comply with certain value-at-risk based leverage limits, to appoint a derivatives risk manager and to provide additional disclosure both publicly and to the SEC regarding its derivatives positions. If a Fund qualifies as limited derivatives user, Rule 18f-4 would require the Fund to have policies and procedures to manage its aggregate derivatives risk. These requirements could have an impact on a Fund, including a potential increase in cost to enter into derivatives transactions and may require a Fund to alter, perhaps materially, its use of derivatives. Compliance with Rule 18f-4 to invest in derivatives and certain related instruments will not be required until approximately the middle of 2022. In connection with the adoption of Rule 18f-4, the SEC also eliminated the asset segregation framework for covering derivatives and certain financial instruments arising from the SEC’s Release 10666 and ensuing staff guidance. As the Funds transition into reliance on Rule 18f-4, approach to asset segregation and coverage requirements described in this SAI with respect to derivatives may be impacted.
Derivatives can be volatile and involve various types and degrees of risk, depending upon the characteristics of the particular derivative and the portfolio as a whole. Derivatives permit a Fund to increase or decrease the level of risk, or change the character of the risk, to which its portfolio is exposed in much the same way as the Fund can increase or decrease the level of risk, or change the character of the risk, of its portfolio by making investments in specific securities. However, derivatives may entail investment exposures that are greater than their cost would suggest, meaning that a small investment in derivatives could have a large potential impact on a Fund’s performance.
If a Fund invests in derivatives at inopportune times or judges market conditions incorrectly, such investments may lower the Fund’s return or result in a loss. A Fund also could experience losses if its derivatives were poorly correlated with the underlying instruments or the Fund’s other investments, or if the Fund were unable to liquidate its position because of an illiquid secondary market. The market for many derivatives is, or suddenly can become, illiquid. Changes in liquidity may result in significant, rapid and unpredictable changes in the prices for derivatives.
Each Fund, as permitted, may take advantage of opportunities in options and futures contracts and options on futures contracts and any other derivatives which are not presently contemplated for use by the Fund or which are not currently available but which may be developed, to the extent such opportunities are both consistent with the Fund’s investment objective and legally permissible for the Fund. Before a Fund enters into such transactions or makes any such investment, the Fund will provide appropriate disclosure in its Prospectuses or this SAI.
The Commodity Futures Trading Commission (“CFTC”) subjects advisers to registered investment companies to regulation by the CFTC if a fund that is advised by the investment adviser either (i) invests, directly or indirectly, more than a prescribed level of its liquidation value in CFTC-regulated futures, options and swaps (“CFTC Derivatives”) or (ii) markets itself as providing investment exposure to such instruments. To the extent a Fund uses CFTC Derivatives, it intends to do so below such prescribed levels and will not market itself as a “commodity pool” or a vehicle for trading such instruments. Accordingly, the Manager has claimed exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act (“CEA”) pursuant to Rule 4.5 under the CEA. The Manager is not, therefore, subject to registration or regulation as a “commodity pool operator” under the CEA in respect of the Funds.

Options
Each of the Funds may purchase put and call options and sell (write) covered put and call options on securities and securities indexes to increase gain or to hedge against the risk of unfavorable price movements. The Funds may only buy or sell options that are listed on a national securities exchange.
A call option on a security is a contract that gives the holder of the option the right, in return for a premium paid, to buy from the writer (seller) of the call option the security underlying the option at a specified exercise price during the term of the option. The writer of the call option has the obligation upon exercise of the option to deliver the underlying security upon payment of the exercise price during the option period. A put option on a security is a contract that, in return for the premium, gives the holder of the option the right to sell to the writer (seller) the underlying security at a specified price during the term of the option. The writer of the put, who receives the premium, has the obligation to buy the underlying security upon exercise at the exercise price during the option period.
A Fund will not sell options that are not covered. A call option written by a Fund on a security is “covered” if the Fund owns the underlying security covered by the call or has an absolute and immediate right to acquire that security without additional cash consideration (or for additional cash consideration held in a segregated account) upon conversion or exchange of other securities held in its portfolio. A call option is also covered if the Fund holds a call on the same security as the call written where the exercise price of the call held is (1) equal to or less than the exercise price of the call written or (2) greater than the exercise price of the call written if the difference is maintained by the Fund in cash or liquid securities in a segregated account. A put option is “covered” if the Fund maintains cash or liquid securities with a value equal to the exercise price in a segregated account, or else holds a put on the same security as the put written where the exercise price of the put held is equal to or greater than the exercise price of the put written.
If a Fund has written an option, it may terminate its obligation by effecting a closing purchase transaction. This is accomplished by purchasing an option of the same series as the option previously written. However, once the Fund has been assigned an exercise notice, the Fund will be unable to effect a closing purchase transaction. Similarly, if a Fund is the holder of an option it may liquidate its position by effecting a closing sale transaction. This is accomplished by selling an option of the same series as the option previously purchased. There can be no assurance that either a closing purchase or sale transaction can be effected when the Fund so desires.
A Fund would realize a profit from a closing transaction if the price of the transaction were less than the premium received from writing the option or is more than the premium paid to purchase the option; the Fund would realize a loss from a closing transaction if the price of the transaction were more than the premium received from writing the option or less than the premium paid to purchase the option. Since call option prices generally reflect increases in the price of the underlying security, any loss resulting from the repurchase of a call option may also be wholly or partially offset by unrealized appreciation of the underlying security. Other principal factors affecting the market value of a put or a call option include supply and demand, interest rates, the current market price and price volatility of the underlying security and the time remaining until the expiration date.
An option position may be closed out only on an exchange which provides a secondary market for an option of the same series. There is no assurance that a liquid secondary market on an exchange will exist for any particular option. In such event it might not be possible to effect closing transactions in particular options, so that the Fund would have to exercise its option in order to realize any profit and would incur brokerage commissions upon the exercise of the options. If the Fund, as a covered call option writer, were unable to effect a closing purchase transaction in a secondary market, it would not be able to sell the underlying security until the option expired or it delivered the underlying security upon exercise or otherwise covered the position.
In addition to options on securities, the Funds may also purchase and sell call and put options on securities indexes. A stock index reflects in a single number the market value of many different stocks. Relative values are assigned to the stocks included in an index and the index fluctuates with changes in the market values of the stocks. The options give the holder the right to receive a cash settlement during the term of the option based on the difference between the exercise price and the value of the index. By
12

writing a put or call option on a securities index, the Fund is obligated, in return for the premium received, to make delivery of this amount. The Fund may offset its position in stock index options prior to expiration by entering into a closing transaction on an exchange or it may let the option expire unexercised.
Use of options on securities indexes entails the risk that trading in the options may be interrupted if trading in certain securities included in the index is interrupted. A Fund will not purchase these options unless Alger Management is satisfied with the development, depth and liquidity of the market and Alger Management believes the options can be closed out.
Price movements in a Fund’s securities may not correlate precisely with movements in the level of an index and, therefore, the use of options on indexes cannot serve as a complete hedge and would depend, in part, on the ability of Alger Management to predict correctly movements in the direction of the stock market generally or of a particular industry. Because options on securities indexes require settlement in cash, Alger Management might be forced to liquidate Fund securities to meet settlement obligations.
Although Alger Management will attempt to take appropriate measures to minimize the risks relating to any trading by the Funds in put and call options, there can be no assurance that a Fund will succeed in any option trading program it undertakes.
Stock Index Futures and Options on Stock Index Futures
(Capital Appreciation Institutional Fund Only)
Futures are generally bought and sold on the commodities exchanges where they are listed with payment of initial and variation margin as described below. The sale of a futures contract creates a firm obligation by a Fund, as seller, to deliver to the buyer the net cash amount called for in the contract at a specific future time. Put options on futures might be purchased to protect against declines in the market values of securities occasioned by a decline in stock prices and securities index futures might be sold to protect against a general decline in the value of securities of the type that comprise the index. Options on futures contracts are similar to options on securities except that an option on a futures contract gives the purchaser the right, in return for the premium paid, to assume a position in a futures contract and obligates the seller to deliver such position.
A stock index future obligates the seller to deliver (and the purchaser to take) an amount of cash equal to a specific dollar amount times the difference between the value of a specific stock index at the close of the last trading day of the contract and the price at which the agreement is made. No physical delivery of the underlying stocks in the index is made. While incidental to its securities activities, the Fund may use index futures as a substitute for a comparable market position in the underlying securities.
If the Fund uses futures, or options thereon, for hedging, the risk of imperfect correlation will increase as the composition of the Fund varies from the composition of the stock index. In an effort to compensate for the imperfect correlation of movements in the price of the securities being hedged and movements in the price of the stock index futures, the Fund may, if it uses a hedging strategy, buy or sell stock index futures contracts in a greater or lesser dollar amount than the dollar amount of the securities being hedged if the historical volatility of the stock index futures has been less or greater than that of the securities. Such “over hedging” or “under hedging” may adversely affect a Fund’s net investment results if market movements are not as anticipated when the hedge is established.
An option on a stock index futures contract, as contrasted with the direct investment in such a contract, gives the purchaser the right, in return for the premium paid, to assume a position in a stock index futures contract at a specified exercise price during the term of the option. The Fund would sell options on stock index futures contracts only as part of closing purchase transactions to terminate its options positions. No assurance can be given that such closing transactions could be effected or that there would be correlation between price movements in the options on stock index futures and price movements in a Fund’s securities which were the subject of the hedge. In addition, any purchase by a Fund of such options would be based upon predictions as to anticipated market trends, which could prove to be inaccurate.
The Fund’s use, if any, of stock index futures and options thereon will in all cases be consistent with applicable regulatory requirements and in particular the rules and regulations of the CFTC and will be entered into only, if at all, for bona fide hedging, risk management or other portfolio management purposes. Typically, maintaining a futures contract or selling an option thereon will require a Fund to deposit with a financial intermediary as security for its obligations an amount of cash or other specified
13

assets (initial margin) which initially is typically 1% to 10% of the face amount of the contract (but may be higher in some circumstances). Additional cash or assets (variation margin) may be required to be deposited thereafter on a daily basis as the mark to market value of the contract fluctuates. The purchase of an option on stock index futures involves payment of a premium for the option without any further obligation on the part of a Fund. If a Fund exercises an option on a futures contract it will be obligated to post initial margin (and potential subsequent variation margin) for the resulting futures position just as it would for any position. Futures contracts and options thereon are generally settled by entering into an offsetting transaction but there can be no assurance that the position can be offset prior to settlement at an advantageous price, or that delivery will occur.
The Fund will not enter into a futures contract or related option (except for closing transactions) if, immediately thereafter, the sum of the amount of its initial margin and premiums on open futures contracts and options thereon would exceed 5% of the Fund’s total assets (taken at current value); however, in the case of an option that is in-the-money at the time of the purchase, the in-the-money amount may be excluded in calculating the 5% limitation.
Borrowing
Each Fund may borrow from banks for temporary or emergency purposes. In addition, Capital Appreciation Institutional Fund may use up to 33 13 percent of its assets to borrow money from banks for investment purposes. This borrowing is known as leveraging. Leveraging increases both investment opportunity and investment risk. If the investment gains on securities purchased with borrowed money exceed the interest paid on the borrowing, the net asset value of a Fund’s shares will rise faster than would otherwise be the case. On the other hand, if the investment gains fail to cover the cost (including interest) of borrowings, or if there are losses, the net asset value of a Fund’s shares will decrease faster than would otherwise be the case. In accordance with the 1940 Act, a Fund is required to maintain continuous asset coverage (that is, total assets including borrowings, less liabilities exclusive of borrowings) of 300% of its borrowings. Maintaining asset coverage of 300% means that a Fund’s liabilities may comprise up to a third of its assets. For example, if a Fund had $100 in total assets, and the Fund borrowed $50, the Fund’s total assets would be $150, and its liabilities would be $50. A Fund would have 300% asset coverage. If such asset coverage should decline below 300% as a result of market fluctuations or other reasons, a Fund may be required to sell some of its portfolio holdings within three days to reduce the debt and restore the 300% asset coverage, even though it may be disadvantageous from an investment standpoint to sell securities at that time. Leveraging may exaggerate the effect on net asset value of any increase or decrease in the market value of a Fund’s securities. Money borrowed for leveraging will be subject to interest costs which may or may not be recovered by appreciation of the securities purchased; in certain cases, interest costs may exceed the return received on the securities purchased. A Fund also may be required to maintain minimum average balances in connection with such borrowing or to pay a commitment or other fee to maintain a line of credit; either of these requirements would increase the cost of borrowing over the stated interest rate.
Interfund Loans
The SEC has granted an exemption permitting the funds advised by Alger Management to participate in an interfund lending program. This program allows the funds to borrow money from and lend money to each other for temporary or emergency purposes. To the extent permitted under its investment restrictions, each Fund may lend uninvested cash in an amount up to 15% of its net assets to other funds, and each Fund may borrow in an amount up to 10% of its net assets from other funds. If a Fund has borrowed from other funds and has aggregate borrowings from all sources that exceed 10% of the Fund’s total assets, such Fund will secure all of its loans from other funds. The ability of the Fund to lend cash to or borrow cash from other funds is subject to certain other terms and conditions. The Board is responsible for overseeing the Trust’s participation in the interfund lending program.
Master Limited Partnerships
Each Fund may invest in master limited partnerships (“MLPs”). An MLP is a publicly traded company organized as a limited partnership or limited liability company and treated as a partnership for federal income tax purposes. MLPs generally have two classes of owners, the general partner and limited partners. The general partner typically controls the partnership’s operations and management. The Funds may purchase publicly traded common units issued to limited partners of MLPs. MLPs combine the tax advantages of a partnership with the liquidity of a publicly traded stock. MLP income is generally not subject to entity-level tax; rather, its income, gain or losses pass through to common unitholders. The
14

value of an MLP generally fluctuates predominantly based on prevailing market conditions and the success of the MLP. Investments held by MLPs may be relatively illiquid, and MLPs themselves may trade infrequently and in limited volume. MLPs involve the risks related to their underlying assets, and risks associated with pooled investment vehicles.
Initial Public Offering (“IPO”) Risk
The volume of IPOs and the levels at which the newly issued stocks trade in the secondary market are affected by the performance of the stock market overall. If IPOs are brought to the market, availability may be limited and a Fund may not be able to buy any shares at the offering price, or if it is able to buy shares, it may not be able to buy as many shares at the offering price as it would like. In addition, the prices of securities involved in IPOs are often subject to greater and more unpredictable price changes than more established stocks. IPOs have the potential to produce substantial gains. There is no assurance that a Fund will have access to profitable IPOs and therefore investors should not rely on any past gains from IPOs as an indication of future performance. The investment performance of a Fund during periods when it is unable to invest significantly or at all in IPOs may be lower than during periods when it is able to do so. In addition, as a Fund increases in size, the impact of IPOs on its performance will generally decrease. Securities issued in IPOs are subject to many of the same risks as investing in companies with smaller market capitalizations. Securities issued in IPOs have no trading history, and information about the companies may be available for very limited periods.
Venture Capital and Private Equity Investments
A Fund may identify investment opportunities that are not yet available in the public markets and that are accessible only through private equity investments, including private investments in public equities (“PIPEs”). To capitalize on such opportunities, the Fund may invest in venture capital or private equity funds, direct private equity investments, PIPEs, and other investments that the Manager determines to have limited liquidity (“Special Investment Opportunities”). Special Investment Opportunities involve an extraordinarily high degree of business and financial risk and can result in substantial or complete losses. There may be no trading market for Special Investment Opportunities, and the sale or transfer of such securities may be limited or prohibited by contract or legal requirements, or may be dependent on an exit strategy, such as an IPO or the sale of a business, which may not occur, or may be dependent on managerial assistance provided by other investors and their willingness to provide additional financial support. Some Special Investment Opportunities in which a Fund may invest may be operating at a loss or with substantial variations in operating results from period to period and may need substantial additional capital to support expansion or to achieve or maintain competitive positions. Such Special Investment Opportunities may face intense competition, including competition from companies with much greater financial resources, much more extensive development, production, marketing and service capabilities and a much larger number of qualified managerial and technical personnel. A Fund can offer no assurance that the marketing efforts of any particular Special Investment Opportunity will be successful or that its business will succeed. Positions in Special Investment Opportunities may be able to be liquidated, if at all, only at disadvantageous prices. As a result, a Fund that holds such positions may be required to do so for several years, if not longer, regardless of adverse price movements. Investment in Special Investment Opportunities may cause a Fund to be less liquid than would otherwise be the case.
With respect to PIPE transactions, PIPE investors purchase securities directly from a publicly traded company in a private placement transaction, typically at a discount to the market price of the company’s common stock. Because the sale of the securities is not registered under the Securities Act, the securities are “restricted” and cannot be immediately resold by the investors into the public markets. Accordingly, the company typically agrees as part of the PIPE deal to register the restricted securities with the SEC. PIPE securities may be deemed illiquid.
Real Estate Investment Trusts (“REITs”)
A Fund may invest in shares of REITs. REITs possess certain risks which differ from an investment in common stocks. REITs are financial vehicles that pool investor’s capital to purchase or finance real estate. REITs may concentrate their investments in specific geographic areas or in specific property types, i.e., hotels, shopping malls, residential complexes and office buildings.
REITs are subject to management fees and other expenses, and a Fund will bear its proportionate share of the costs of the REITs’ operations. There are three general categories of REITs: equity REITs, mortgage REITs and hybrid REITs. Equity REITs invest primarily in direct fee ownership or leasehold
15

ownership of real property; they derive most of their income from rents. Mortgage REITs invest mostly in mortgages on real estate, which may secure construction, development or long-term loans; the main source of their income is mortgage interest payments. Hybrid REITs hold both ownership and mortgage interests in real estate.
Investing in REITs involves certain unique risks in addition to those risks associated with investing in the real estate industry in general. The market value of REIT shares and the ability of the REITs to distribute income may be adversely affected by several factors, including rising interest rates, changes in the national, state and local economic climate and real estate conditions, perceptions of prospective tenants of the safety, convenience and attractiveness of the properties, the ability of the owners to provide adequate management, maintenance and insurance, the cost of complying with the Americans with Disabilities Act, increased competition from new properties, the impact of present or future environmental legislation and compliance with environmental laws, failing to maintain their exemptions from registration under the 1940 Act, changes in real estate taxes and other operating expenses, adverse changes in governmental rules and fiscal policies, adverse changes in zoning laws and other factors beyond the control of the issuers of the REITs. In addition, distributions received by a Fund from REITs may consist of dividends, capital gains and/or return of capital. As REITs generally pay a higher rate of dividends (on a pre-tax basis) than operating companies, to the extent application of a Fund’s investment strategy results in the Fund investing in REIT shares, the percentage of the Fund’s dividend income received from REIT shares will likely exceed the percentage of the Fund’s portfolio which is comprised of REIT shares. Ordinary REIT dividends received by a Fund and distributed to the Fund’s shareholders will generally be taxable as ordinary income and will not constitute “qualified dividend income.” However, for tax years beginning after December 31, 2017 and before January 1, 2026, a non-corporate taxpayer who is a direct REIT shareholder may claim a 20% “qualified business income” deduction for ordinary REIT dividends, and a regulated investment company may report dividends as eligible for this deduction to the extent the regulated investment company’s income is derived from ordinary REIT dividends (reduced by allocable regulated investment company expenses). A shareholder may treat the dividends as such provided the regulated investment company and the shareholder satisfy applicable holding period requirements.
REITs (especially mortgage REITs) are also subject to interest rate risk. Rising interest rates may cause REIT investors to demand a higher annual yield, which may, in turn, cause a decline in the market price of the equity securities issued by a REIT. Rising interest rates also generally increase the costs of obtaining financing, which could cause the value of a Fund’s REIT investments to decline. During periods when interest rates are declining, mortgages are often refinanced. Refinancing may reduce the yield on investments in mortgage REITs. In addition, since REITs depend on payment under their mortgage loans and leases to generate cash to make distributions to their shareholders, investments in REITs may be adversely affected by defaults on such mortgage loans or leases.
Investing in certain REITs, which often have small market capitalizations, may also involve the same risks as investing in other small capitalization companies. REITs may have limited financial resources and their securities may trade less frequently and in limited volume and may be subject to more abrupt or erratic price movements than larger company securities. Historically, small capitalization stocks, such as REITs, have been more volatile in price than the larger capitalization stocks such as those included in the S&P 500 Index. The management of a REIT may be subject to conflicts of interest with respect to the operation of the business of the REIT and may be involved in real estate activities competitive with the REIT. REITs may own properties through joint ventures or in other circumstances in which the REIT may not have control over its investments. REITs may incur significant amounts of leverage.
Cyber Security Risk
With the increasing use of the internet and technology in connection with Fund operations, the Funds and their service providers are susceptible to greater operational and information security risks through breaches of cyber security. Cyber security breaches include stealing or corrupting data maintained online or digitally, “denial of service” attacks on websites, the unauthorized monitoring, misuse, loss, destruction or corruption of confidential information, unauthorized access to systems, compromises to networks or devices that the Funds and their service providers use to service Fund operations, and operational disruption or failures in the physical infrastructure or operating systems that support the Funds and their service providers. Cyber security breaches affecting a Fund or any of the Fund’s intermediaries or service providers may adversely impact the Fund and its shareholders, potentially resulting in financial losses or the inability of Fund shareholders to transact business. For instance, cyber security breaches may interfere with the processing of shareholder transactions, impact a Fund’s ability to
16

calculate NAVs, cause the release of private shareholder information or confidential business information, impede trading, subject the Funds to regulatory fines or financial losses and/or cause reputational damage. The Funds may also incur additional costs for cyber security risk management programs designed to mitigate or prevent the risk of cyber security breaches. Such costs may be ongoing because threats of cyber attacks are constantly evolving. Issuers of securities in which the Funds invest are also subject to similar cyber security risks, which could result in material adverse consequences for such issuers, and may cause the Fund’s investment in such companies to lose value. There can be no assurance that the Funds or their service providers, or the issuers of the securities in which the Funds invest, will not suffer losses relating to cyber security breaches in the future.
London Interbank Offered Rate (“LIBOR”) Replacement and Other Reference Rates Risk
Many debt securities, derivatives and other financial instruments, including some of the Funds’ investments, utilize benchmark or reference rates such as LIBOR, European Interbank Offer Rate (“EURIBOR”), Sterling Overnight Interbank Average Rate (“SONIA”) and other similar types of reference rates for variable interest rate calculations. Instruments in which a Fund invests may pay interest at floating rates based on LIBOR or other similar types of reference rates or may be subject to interest caps or floors based on such reference rates. A Fund and issuers of instruments in which the Fund invests may also obtain financing at floating rates based on such reference rates. The elimination of a reference rate or any other changes or reforms to the determination or supervision of reference rates could have an adverse impact on the market for—or value of—any securities or payments linked to those reference rates.
The UK Financial Conduct Authority announced a phase out of LIBOR such that after June 30, 2023, the overnight, 1-month, 3-month, 6-month and 12-month U.S. dollar LIBOR settings will cease to be published or will no longer be representative. All other LIBOR settings and certain other interbank offered rates, such as the Euro Overnight Index Average (“EONIA”), ceased to be published or representative after December 31, 2021. Various financial industry groups have been planning for the transition away from LIBOR, but there remain challenges to converting certain securities and transactions to a new reference rate (e.g., the Secured Overnight Financing Rate (“SOFR”), which is intended to replace the U.S. dollar LIBOR). Proposals for alternative reference rates for other currencies have also been announced or have already begun publication, such as SONIA in the UK.
Markets are slowly developing in response to these new rates, and transition planning is at a relatively early stage. Neither the effect of the transition process nor its ultimate success is known. The transition process may lead to increased volatility and illiquidity in markets that currently rely on LIBOR to determine interest rates. The effect of any changes to—or discontinuation of—LIBOR on a Fund will vary depending on, among other things, provisions in individual contracts and whether, how, and when industry participants develop and adopt new reference rates and alternative reference rates for both legacy and new products and instruments. All of the aforementioned may adversely affect a Fund’s performance or NAV.
Investment Restrictions
The investment restrictions numbered 1 through 12 below have been adopted by the Trust with respect to each of the Funds as fundamental policies. Under the 1940 Act, a “fundamental” policy may not be changed without the vote of a “majority of the outstanding voting securities” of the Fund, which is defined in the 1940 Act as the lesser of (a) 67% or more of the shares present at a Fund meeting if the holders of more than 50% of the outstanding shares of the Fund are present or represented by proxy or (b) more than 50% of the outstanding shares. A fundamental policy affecting a particular Fund may not be changed without the vote of a majority of the outstanding voting securities of the affected Fund. Each Fund’s investment objective is a fundamental policy.
The investment policies adopted by the Trust prohibit each Fund from:
1. Purchasing the securities of any issuer, other than U.S. Government securities, if as a result more than five percent of the value of a Fund’s total assets would be invested in the securities of the issuer, except that up to 25% of the value of the Fund’s total assets may be invested without regard to this limitation.
2. Purchasing more than 10% of the voting securities of any one issuer or more than 10% of the securities of any class of any one issuer. This limitation shall not apply to investments in U.S. Government securities.
17

3. Selling securities short or purchasing securities on margin, except that the Fund may obtain any short-term credit necessary for the clearance of purchases and sales of securities. These restrictions shall not apply to transactions involving selling securities “short against the box.”
4. Borrowing money, except that all Funds may borrow for temporary or emergency purposes including the meeting of redemption requests that might otherwise require the untimely disposition of securities, in an amount not exceeding 10% of the value of the Fund’s total assets (including the amount borrowed) valued at the lesser of cost or market, less liabilities (not including the amount borrowed) at the time the borrowing is made. Whenever borrowings exceed five percent of the value of a Fund’s total assets, the Fund, other than Capital Appreciation Institutional Fund, will not make any additional investments. Capital Appreciation Institutional Fund may also borrow from banks for investment (leveraging) purposes. Immediately after any such borrowing, the Fund will maintain asset coverage of not less than 300% with respect to all borrowings.
5. Pledging, hypothecating, mortgaging or otherwise encumbering more than 10% of the value of the Fund’s total assets, except in connection with borrowings.
6. Issuing senior securities, except that Capital Appreciation Institutional Fund may borrow from banks for investment purposes so long as the Fund maintains the required asset coverage.
7. Underwriting the securities of other issuers, except insofar as the Fund may be deemed to be an underwriter under the Securities Act by virtue of disposing of portfolio securities.
8. Making loans to others, except through purchasing qualified debt obligations, lending portfolio securities or entering into repurchase agreements.
9. Investing in securities of other investment companies, except as they may be acquired as part of a merger, consolidation, reorganization, acquisition of assets or offer of exchange.
10. Purchasing any securities that would cause more than 25% of the value of the Fund’s total assets to be invested in the securities of issuers conducting their principal business activities in the same industry; provided that there shall be no limit on the purchase of U.S. Government securities.
11. Investing in commodities except that Capital Appreciation Institutional Fund may purchase or sell stock index futures contracts and related options thereon if thereafter no more than 5% of its total assets are invested in margin and premiums.
12. Purchasing or selling real estate or real estate limited partnerships, except that the Fund may purchase and sell securities secured by real estate, mortgages or interests therein and securities that are issued by companies that invest or deal in real estate.
Notations Regarding the Investment Restrictions
The following notations are not considered to be part of a Fund’s fundamental investment restrictions and are subject to change without shareholder approval.
Except in the case of the 300% limitation set forth in Investment Restriction No. 4, the percentage limitations contained in the foregoing restrictions apply at the time of purchase of the securities and a later increase or decrease in percentage resulting from a change in the values of the securities or in the amount of the Fund’s assets will not constitute a violation of the restriction. With respect to the percentage limitation set forth in Investment Restriction No. 1, however, if borrowings exceed 33 13% of the value of the Fund’s total assets as a result of a change in values or assets, the Fund shall take steps to reduce such borrowings within three days (not including Sundays and holidays) thereafter at least to the extent of such excess.
For purposes of Investment Restriction No. 10, subject to applicable law and except as may be stated otherwise, each Fund considers any single industry to also include a particular group of related industries.
Portfolio Transactions
Decisions to buy and sell securities and other financial instruments for a Fund are made by Alger Management, which also is responsible for placing these transactions, subject to the overall review of the Board. Although investment requirements for each Fund are reviewed independently from those of the other accounts or funds managed by Alger Management, investments of the type the Funds may make
18

may also be made by these other accounts or funds. When a Fund and one or more other funds or other accounts managed by Alger Management are prepared to invest in, or desire to dispose of, the same security or other financial instrument, available investments or opportunities for sales will be allocated in a manner believed by Alger Management to be equitable to each. In some cases, this procedure may affect adversely the price paid or received by a Fund or the size of the position obtained or disposed of by a Fund.
Transactions in equity securities are in most cases effected on U.S. and foreign stock exchanges or in over-the-counter markets and involve the payment of negotiated brokerage commissions. Where there is no stated commission, as in the case of certain securities traded in the over-the-counter markets, the prices of those securities include undisclosed commissions or mark-ups. Purchases and sales of money market instruments and debt securities usually are principal transactions. These securities are normally purchased directly from the issuer or from an underwriter or market maker for the securities. The cost of securities purchased from underwriters includes an underwriting commission or concession and the prices at which securities are purchased from and sold to dealers include a dealer’s mark-up or mark-down. U.S. Government securities are generally purchased from underwriters or dealers, although certain newly-issued U.S. Government securities may be purchased directly from the U.S. Treasury or from the issuing agency or instrumentality.
In Alger Management’s view, companies are organic entities that continuously undergo changes in response to, among other things, economic, market, environmental, technological, political and managerial factors. Generally, securities will be purchased for capital appreciation. As a result, the Funds may dispose of securities without regard to the time they have been held when such action, for defensive or other purposes, appears advisable. Moreover, it is Alger Management’s philosophy to pursue each Fund’s investment objective by managing these Funds actively, which may result in high portfolio turnover. The portfolio turnover rate for each Fund is included in the Fund’s Summary Prospectus as well as the financial highlights section of the Fund’s Prospectus. Increased portfolio turnover will have the effect of increasing a Fund’s brokerage and custodial expenses.
To the extent consistent with applicable provisions of the 1940 Act and the rules and exemptions adopted by the SEC thereunder, as well as other regulatory requirements, the Board has determined that portfolio transactions will generally be executed through Fred Alger & Company, LLC (“Alger LLC” or the “Distributor”), a registered broker-dealer, if, in the judgment of Alger Management, the use of Alger LLC is likely to result in price and execution at least as favorable as those of other qualified broker-dealers and if, in particular transactions, Alger LLC charges the Fund involved a rate consistent with that which other broker-dealers charge to comparable unaffiliated customers in similar transactions. Over-the-counter purchases and sales are transacted directly with principal market makers except in cases in which better prices and executions may be obtained elsewhere. Principal transactions are not entered into with affiliates of the Fund except pursuant to exemptive rules or orders adopted by the SEC.
In selecting brokers or dealers to execute portfolio transactions on behalf of a Fund, Alger Management seeks the best overall terms available. In assessing the best overall terms available for any transaction, Alger Management will consider the factors it deems relevant, including the breadth of the market in the investment, the price of the investment, the financial condition and execution capability of the broker or dealer and the reasonableness of the commission, if any, for the specific transaction and on a continuing basis. In addition, Alger Management is authorized, in selecting parties to execute a particular transaction and in evaluating the best overall terms available, to consider the brokerage and research services, as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934, as amended, provided to the Fund involved, the other Funds and/or other accounts over which Alger Management or its affiliates exercise investment discretion to the extent permitted by law. Alger Management’s fees under its agreements with the Funds are not reduced by reason of its receiving brokerage and research services. The Board will periodically review the commissions paid by the Funds to determine if the commissions paid over representative periods of time are reasonable in relation to the benefits inuring to the Funds. Neither Alger LLC nor its affiliates engage in principal transactions with the Funds and, accordingly, received no compensation in connection with securities purchased or sold in that manner, which include securities traded in the over-the-counter markets, money market investments and most debt securities.

Disclosure of Portfolio Holdings
The Board has adopted policies and procedures relating to disclosure of the Funds’ portfolio securities. These policies and procedures recognize that there may be legitimate business reasons for holdings to be disclosed and seek to balance those interests to protect the proprietary nature of the trading strategies and implementation thereof by the Funds.
Generally, the policies prohibit the release of information concerning portfolio holdings which have not previously been made public to individual investors, institutional investors, intermediaries that distribute the Funds’ shares and other parties which are not employed by the Manager or its affiliates except when the legitimate business purposes for selective disclosure and other conditions (designed to protect the Funds) are acceptable.
The Funds make their full holdings available semi-annually in shareholder reports filed on Form N-CSR and after the first and third fiscal quarters as an exhibit to their regulatory filings on Form N-PORT. These shareholder reports and regulatory filings are filed with the SEC, as required by federal securities laws, and are generally available within sixty (60) days of the end of the Funds’ fiscal quarter.
In addition, the Funds make publicly available their respective month-end top 10 holdings with a 10 day lag and their month-end full portfolios with a 60 day lag on their website www.alger.com and through other marketing communications (including printed advertising/sales literature and/or shareholder telephone customer service centers). No compensation or other consideration is received for the non-public disclosure of portfolio holdings information.
In accordance with the foregoing, the Funds provide portfolio holdings information to third parties including financial intermediaries and service providers who need access to this information in the performance of their services and are subject to duties of confidentiality (1) imposed by law, including a duty not to trade on non-public information, and/or (2) pursuant to an agreement that confidential information is not to be disclosed or used (including trading on such information) other than as required by law. This agreement must be approved by the Funds’ Chief Compliance Officer.
The Board periodically reviews a report disclosing the third parties to whom each Fund’s holdings information has been disclosed and the purpose for such disclosure, and it considers whether or not the release of information to such third parties is in the best interest of the Fund and its shareholders.
In addition to material the Funds routinely provide to shareholders, the Manager may, upon request, make additional statistical information available regarding the Alger Family of Funds. Such information may include, but not be limited to, relative weightings and characteristics of a Fund portfolio versus an index (such as P/E (or price to book) ratio), EPS forecasts, alpha, beta, capture ratio, maximum drawdown, standard deviation, Sharpe ratio, information ratio, and market cap analysis), security specific impact on overall portfolio performance, return on equity statistics, geographic analysis, number of holdings, month-end top ten contributors to and detractors from performance, portfolio turnover, and other similar information. Shareholders should visit www.alger.com or may also contact the Funds at (800) 992-3863 to obtain such information.
Each Fund provides its portfolio holdings on a daily basis, with no lag, to each of Abel Noser, Bloomberg, Factset, Security Class Action Services, LLC, and William O’Neil + Co. Inc. Each Fund has ongoing arrangements to provide its portfolio holdings to each of Callan Associates, Epiq eDiscovery Solutions, Inc., Equest, eVestment Alliance, LLC, Fascet LLC, ICE Data Services, InsiderScore, Mercer Investment Consulting, Morningstar, Oppenheimer, PSN, S&P Global Inc., RBC Capital Markets, Refinitiv US LLC, Renaissance Macro, Seismic, Synergy Capital Management, Vantagepoint Investment Management, Inc., and Wilshire. Neither a Fund nor any other person is directly compensated for such disclosure, although certain persons receiving such disclosure may be investors in one or more Funds and may therefore be subject to fees applicable to all shareholders. Alger Management also manages accounts for individuals and institutions. Holders of these accounts may own many of the same securities as a Fund, and therefore may be generally aware of the portfolio holdings of a Fund.

Net Asset Value
The price of one share of a class is based on its “net asset value.” The net asset value is computed by adding the value of the Fund’s investments plus cash and other assets allocable to the class, deducting applicable liabilities and then dividing the result by the number of shares of the class outstanding. The net asset value of a share of a given class may differ from that of one or more other classes of the Fund. Net asset value is calculated as of the close of business (normally 4:00 p.m. Eastern time) on each day the New York Stock Exchange (“NYSE”) is open.
Purchases of shares will be based upon the next net asset value calculated for each class after your order is received and accepted by the Transfer Agent or other designated intermediary. If your purchase is made by check, wire or exchange and is received by the close of business of the NYSE (normally 4:00 p.m. Eastern time), your account will be credited on the day of receipt. If your purchase is received after such time, it will be credited the next business day.
The NYSE is generally open on each Monday through Friday, except New Year’s Day, Martin Luther King, Jr. Day (the third Monday in January), Presidents’ Day (the third Monday in February), Good Friday, Memorial Day (the last Monday in May), Juneteenth, Independence Day, Labor Day (the first Monday in September), Thanksgiving Day (the fourth Thursday in November) and Christmas Day.
The assets of the Funds are generally valued on the basis of market quotations. Securities for which such information is readily available are valued at the last reported sales price or, in the absence of reported sales, at a price within the bid and asked price or the official closing price as reported by an independent pricing service on the primary market or exchange on which they are traded. In the absence of a recent bid or asked price, the equivalent as obtained from one or more of the major market makers for the securities to be valued may be used. Other investments and other assets, including restricted securities and securities for which market quotations are not readily available, are valued at fair value under procedures approved by the Board. Short-term securities with maturities of 60 days or less are valued at amortized cost, as described below, which constitutes fair value as determined by the Board.
Securities in which the Funds invest may be traded in markets that close before the close of the NYSE. Developments that occur between the close of these markets (generally foreign markets) and the close of the NYSE (normally 4:00 p.m. Eastern time) may result in adjustments to the closing prices to reflect what the investment manager, pursuant to policies established by the Board, believes to be fair values of these securities as of the close of the NYSE. The Funds may also fair value securities in other situations, for example, when a particular foreign market is closed but the Funds are open.
The valuation of money market instruments with maturities of 60 days or less held by the Funds is based on their amortized cost which does not take into account unrealized capital gains or losses. Amortized cost valuation involves initially valuing an instrument at its cost and thereafter assuming a constant amortization to maturity of any discount or premium, regardless of the impact of fluctuating interest rates on the market value of the instrument. Although this method provides certainty in valuation, it may result in periods during which value, as determined by amortized cost, is higher or lower than the price a Fund would receive if it sold the instrument.
Classes of Shares
Capital Appreciation Institutional Fund offers four classes of shares (Class I, R, Y and Z-2 shares). Focus Equity Fund offers five classes of shares (Class A, C, I, Y and Z Shares). Each of Mid Cap Institutional Growth Fund and Small Cap Growth Institutional Fund offers three classes of shares (Class I, R and Z-2 Shares). Class I, R, Y, Z and Z-2 Shares are offered only to institutional investors, in separate prospectuses. Class A Shares are generally subject to a front-end load, and Class C Shares are generally subject to a contingent deferred sales charge (“CDSC”). Class Z Shares may also be available on brokerage platforms of firms that have agreements with the Funds’ distributor to offer such shares solely when acting as an agent for the investor. An investor transacting in Class Z Shares in these programs may be required to pay a commission and/or other forms of compensation to the broker. Class I, Class R, Class Y, Class Z and Class Z-2 Shares are not subject to a sales charge of either kind. Each of these classes of shares is subject to distribution and/or service fees, except that Class Y, Z and Z-2 Shares are sold without a distribution or service fee. Effective August 27, 2019, Class C shares are only offered to investors through certain Financial Intermediaries, group retirement plan recordkeeping platforms or whose shares are held in an omnibus account.
22

From time to time, Alger LLC may reallow to brokers or financial intermediaries all or substantially all of the initial sales charge on Class A Shares. To the extent that it does so, such persons may be deemed to be underwriters of the Fund as defined in the Securities Act.
Current total return figures may be obtained by calling Alger Funds at (800) 992-3863 or on the Funds’ website at www.alger.com.
Conversion of Class C Shares
Class C Shares will automatically convert to Class A Shares on the fifth business day of the month following the eighth anniversary of the purchase date and will thereafter be subject to the lower Class A distribution and/or service fees. The conversion will be calculated based on the NAV per share without the imposition of any sales charge, fee or other charge. At conversion, a proportionate amount of Class C Shares representing reinvested dividends distributions will also be converted into Class A Shares.
Shareholders who purchase Class C Shares through certain Financial Intermediaries, group retirement plan recordkeeping platforms or whose shares are held in an omnibus account may not be eligible to participate in such Class C Share conversions. Contact your Financial Intermediary or plan recordkeeper for eligibility information. See Appendix A to each Fund’s Class C Shares prospectus for further details.
Purchases
Shares of the Funds are offered continuously by the Trust and are distributed on a best efforts basis by Alger LLC as principal underwriter for the Funds pursuant to a distribution agreement (the “Distribution Agreement”). Under the Distribution Agreement, Alger LLC bears all selling expenses, including the costs of advertising and of printing prospectuses and distributing them to prospective shareholders.
The Funds do not accept cash or cash equivalents for share purchases. Third-party checks will not be honored except in the case of employer-sponsored retirement plans. You will be charged a fee for any check returned by your bank. Purchases made through ACH (Automated clearing house) are subject to a maximum limit of $50,000.
Orders received by the Trust’s transfer agent or other designated intermediary are effected on days on which the NYSE is open for trading. For orders received before the close of regular trading on the NYSE, purchases and redemptions of the shares of each Fund are effected at the respective net asset values per share determined as of the close of regular trading on the NYSE on that same day. Orders received after the close of regular trading on the NYSE are effected at the next calculated net asset value. See “Net Asset Value.” All orders for the purchase of shares are subject to acceptance or rejection by the Trust. Payment for redemptions will be made by the Trust’s transfer agent on behalf of the Trust and the relevant Funds within seven days after the request is received.
Investors may exchange stock of companies acceptable to Alger Management for shares of the Funds with a minimum of 100 shares of each company generally being required. The Trust believes such exchange provides a means by which holders of certain securities may invest in the Funds without the expense of selling the securities in the open market. The investor should furnish, either in writing or by telephone, to Alger Management a list with a full and exact description of all securities proposed for exchange. Alger Management will then notify the investor as to whether the securities are acceptable and, if so, will send a letter of transmittal to be completed and signed by the investor. Alger Management has the right to reject all or any part of the securities offered for exchange. The securities must then be sent in proper form for transfer with the letter of transmittal to the Custodian of the Fund’s assets. The investor must certify that there are no legal or contractual restrictions on the free transfer and sale of the securities. Upon receipt by the Custodian, the securities will be valued as of the close of business on the day of receipt in the same manner as the Fund’s securities are valued each day. Shares of the Fund having an equal net asset value as of the close of the same day will be registered in the investor’s name. Applicable sales charges, if any, will apply, but there is no charge for making the exchange and no brokerage commission on the securities accepted, although applicable stock transfer taxes, if any, may be deducted. The exchange of securities by the investor pursuant to this offer may constitute a taxable transaction and may result in a gain or loss for federal income tax purposes. The tax treatment experienced by investors may vary depending upon individual circumstances. Each investor should consult a tax adviser to determine federal, state and local tax consequences.
23

Confirmations and Account Statements
All of your transactions through the Transfer Agent, UMB Fund Services, Inc., will be confirmed on separate written transaction confirmations (other than Automatic Investment Plan transactions) and on periodic account statements. You should promptly and carefully review the transaction confirmations and periodic statements provided to you and notify the Transfer Agent in writing of any discrepancy or unauthorized account activity. Any information contained on transaction confirmations and account statements will be conclusive unless you notify the Transfer Agent of an apparent discrepancy or unauthorized account activity within ten (10) business days after the information is transmitted to you.
Shareholder Servicing Agreement
In connection with the shareholder servicing activities of Alger LLC in respect of each Fund’s Class I and Class R Shares, the Trust has adopted a shareholder servicing agreement (the “Shareholder Servicing Agreement”). The Shareholder Servicing Agreement authorizes the Trust to pay Alger LLC, on behalf of each Fund, a shareholder servicing fee computed at an annual rate of up to 0.25% of the average daily net assets allocable to the Class I or Class R Shares, as the case may be, of a Fund, and such fee shall be charged only to that class. The shareholder servicing fee is used by Alger LLC to provide compensation for ongoing servicing and/or maintenance of Class I or Class R shareholder accounts in each Fund and to cover an allocable portion of overhead and other Alger LLC and selected dealer office expenses related to the servicing and/or maintenance of Class I or Class R shareholder accounts. Compensation will be paid by Alger LLC to persons, including Alger LLC employees, who respond to inquiries of Class I or Class R shareholders of a Fund regarding their ownership of Class I or Class R shares or their accounts with the Fund or who provide other similar services not otherwise required to be provided by the Manager, Transfer Agent or other agent of a Fund.
Alger LLC has acknowledged that payments under the Shareholder Servicing Agreement are subject to the approval of the Board and that no Fund is contractually obligated to make payments in any amount or at any time, including payments in reimbursement of Alger LLC for expenses and interest thereon incurred in a prior year. Under its terms, the Shareholder Servicing Agreement remains in effect from year to year, provided such continuation is approved annually by a vote of a majority of the Trustees and of a majority of the Trustees who are not “interested persons” (as defined in the 1940 Act) of the Trust (“Independent Trustees”) and who have no direct or indirect financial interest in the operation of the Shareholder Servicing Agreement (such Trustees, the “Servicing Agreement Independent Trustees”). All material amendments to the Shareholder Servicing Agreement must be approved by a majority vote of the Trustees, including a majority of the Servicing Agreement Independent Trustees, at a meeting called for that purpose. The Shareholder Servicing Agreement may be terminated at any time with respect to any Fund without the payment of penalty, by vote of a majority of the Servicing Agreement Independent Trustees or, with respect to the class of shares of a Fund to which the Shareholder Servicing Agreement relates, by a vote of a majority of the outstanding voting securities of the class on not more than 60 days' written notice to Alger LLC.
During the fiscal year ended October 31, 2021, the Funds reimbursed Alger LLC for shareholder servicing activities under the provisions of the Shareholder Servicing Agreement, as follows:

Distribution Plans
Under a distribution plan (the “Plan”) adopted in accordance with Rule 12b-1 under the 1940 Act, each Fund may pay Alger LLC a fee, at an annual rate of up to 0.50% of the average daily net assets of the Fund allocable to Class R Shares of the Fund, if any, primarily for remittance to qualified plan service providers and other financial intermediaries as compensation for distribution assistance and shareholder services with respect to Class R Shares. The Plan is a “compensation” type plan and permits the payment at an annual rate of up to 0.50% of the average daily net assets allocable to the Class R Shares of a Fund for recordkeeping and administrative services as well as activities that are primarily intended to result in sales of Class R Shares of the Fund, including but not limited to preparing, printing and distributing prospectuses, SAI, shareholder reports, and educational materials to investors; compensating selling
24

personnel; responding to inquiries by investors; receiving and answering correspondence; investor-level recordkeeping and administrative services; and similar activities. The Trustees unanimously approved the Plan on December 11, 2002, and it became effective on January 27, 2003. The Plan and any related agreement that is entered into by the Trust in connection with the Plan will continue in effect for a period of more than one year only so long as continuance is specifically approved at least annually by a vote of a majority of the Trustees and of a majority of the Independent Trustees who have no direct or indirect financial interest in the operation of the Plan or any related agreements. All material amendments to the Plan must be approved by a majority vote of the Trustees, including a majority of the Independent Trustees, at a meeting called for that purpose. The Plan may not be amended to increase materially the amount to be spent with respect to a Fund without the approval of the Class R shareholders of the Fund. In addition, the Plan may be terminated with respect to any Fund at any time, without penalty, by vote of a majority of the outstanding Class R Shares of the Fund or by vote of a majority of the Independent Trustees. During the fiscal year ended October 31, 2021, the Funds paid Alger LLC for distribution services under the provisions of the Class Plan, as follows:

As stated in the Prospectus, in connection with the distribution and shareholder servicing activities of Alger LLC in respect of the Focus Equity Fund’s Class A and C Shares, respectively, the Trust has adopted Plans in accordance with Rule 12b-1 under the 1940 Act. Under the Class C Plan, a portion of the distribution fee paid to Alger LLC by the Trust under the Plan, sometimes described as an “asset-based sales charge,” allows investors to buy shares with little or no initial sales charge while allowing Alger LLC to compensate dealers that sell Class C shares of the Fund. Typically, Alger LLC, in its discretion or pursuant to dealer agreements, pays sales commissions of up to 1% of the amount invested in Class C Shares, and pays the asset-based sales charge as an ongoing commission to dealers on Class C Shares that have been outstanding for more than a year. For Class C Shares, the asset-based sales charge is retained by Alger LLC in the first year after purchase; in subsequent years, all or a portion of it typically is paid to the dealers who sold the Class C Shares. In some cases, the selling dealer is Alger LLC. Shareholders of Class A and C of the Fund adopted a Plan when the Class commenced operations.
Each Plan authorizes the Trust to pay Alger LLC, on behalf of the Focus Equity Fund, a shareholder servicing fee computed at an annual rate of up to 0.25% of the average daily net assets allocable to the Class A or Class C Shares, as the case may be, of the Fund, and such fee shall be charged only to that class. The shareholder servicing fee is used by Alger LLC to provide compensation for ongoing servicing and/or maintenance of shareholder accounts and to cover an allocable portion of overhead and other Alger LLC and selected dealer office expenses related to the servicing and/or maintenance of shareholder accounts. Compensation will be paid by Alger LLC to persons, including Alger LLC employees, who respond to inquiries of shareholders of the Fund regarding their ownership of shares or their accounts with the Fund or who provide other similar services not otherwise required to be provided by the Fund’s Manager, Transfer Agent or other agent of the Fund.
Pursuant to the Plan for Class C Shares, the Focus Equity Fund pays an annual fee of 1.00% of its Class C Shares’ average daily net assets to Alger LLC. In addition to the 0.25% shareholder servicing fee, Alger LLC is paid a 0.75% fee for providing distribution services including, but not limited to, organizing
25

and conducting sales seminars, advertising programs, payment of finders’ fees, printing of prospectuses and SAIs and reports for potential investors, preparation and distribution of advertising material and sales literature, overhead, supplemental payments to dealers and other institutions as asset-based charges or as payments of commissions, and the costs of administering the Plan.
During the fiscal year ended October 31, 2021, the Funds paid Alger LLC for distribution services and/or shareholder servicing under the provisions of the respective Class Plans, as follows:
Fund
Class A
Class C
Alger Focus Equity Fund
$255,912

Alger LLC has acknowledged that payments under any Plan are subject to the approval of the Board and that the Fund is not contractually obligated to make payments in any amount or at any time, including payments in reimbursement of Alger LLC for expenses and interest thereon incurred in a prior year.
Under its terms, each Plan remains in effect from year to year, provided such continuation is approved annually by vote of the Board, including a majority of the Independent Trustees who have no direct or indirect financial interest in the operation of the Plan or any related agreements. The Plans may not be amended to increase materially the amount to be spent for the services provided by Alger LLC without the approval of Fund shareholders of the applicable class, and all material amendments of the Plans must be approved by the Trustees in the manner described above. The Plans may be terminated at any time, without penalty, by vote of a majority of the Independent Trustees or, with respect to the class of shares of the Fund to which a Plan relates, by a vote of a majority of the outstanding voting securities of the class, on not more than 30 days’ written notice to Alger LLC. Alger LLC provides to the Board quarterly reports of amounts expended under each Plan and the purpose for which such expenditures were made.
Alger LLC’s selling expenses during the fiscal year ended October 31, 2021 for Focus Equity Fund were as follows:

Expenses of the Funds
Subject to any expense limitations described in each Fund’s Prospectuses, each Fund will bear its own expenses. Operating expenses for each Fund generally consist of all costs not specifically borne by Alger Management, including investment management fees, fees for necessary professional and brokerage services, costs of regulatory compliance and costs associated with maintaining legal existence and shareholder relations. In addition, Class A and Class C Shares of Focus Equity Fund may pay Alger LLC for expenses incurred in distributing shares of that class and the Fund may compensate Alger LLC for servicing shareholder accounts. Class R Shares of the Funds also may pay Alger LLC for Class R distribution expenses. Trustwide expenses not identifiable to any particular Fund or class will be allocated in a manner deemed fair and equitable by the Board. From time to time, Alger Management, in its sole discretion and as it deems appropriate, may assume certain expenses of one or more of the Funds while retaining the ability to be paid by the applicable Fund for such amounts prior to the end of the fiscal year. This will have the effect of lowering the applicable Fund’s overall expense ratio and of increasing yield to investors, or the converse, at the time such amounts are assumed or reimbursed, as the case may be.
Purchases Through Processing Organizations
You can purchase and redeem shares through a “Processing Organization,” which is a broker-dealer, bank or other financial institution that purchases shares of the Funds for its clients or customers. The Trust may authorize a Processing Organization to receive, or to designate other financial organizations to receive, purchase and redemption orders on each Fund’s behalf. In that case, the Fund will be deemed to have received an order when the Processing Organization or its intermediary receives it in good order, and the order will be processed based on the net asset value of the Fund next calculated after the order is received in proper form by the Processing Organization or its designee.

When shares are purchased this way, the Processing Organization, rather than its customer, may be the shareholder of record of the shares. The minimum initial and subsequent investments in classes of the Funds for shareholders who invest through a Processing Organization will generally be set by the Processing Organization. Processing Organizations may impose charges and restrictions in addition to or different from those applicable if you invest in the Fund directly. Therefore, you should read the materials provided by the Processing Organization in conjunction with the applicable Prospectus. Certain Processing Organizations may receive compensation from the Fund, Alger LLC, or any of its affiliates.
Automatic Investment Plan (Class A and C)
While there is no charge to shareholders for this service, a fee will be deducted from a shareholder’s Fund account in the case of insufficient funds. A shareholder’s Automatic Investment Plan may be terminated at any time without charge or penalty by the shareholder, the Trust, the Transfer Agent or Alger LLC. Transfers from your bank account to a Trust-sponsored retirement account are considered current-year contributions. If the day of the month you select falls on a weekend or a NYSE holiday, the purchase will be made on the next business day. Class A Share purchases will remain subject to the initial sales charge.
Right of Accumulation (Class A)
Class A Shares of the Focus Equity Fund may be purchased by “any person” (which includes an individual, his or her spouse or domestic partner and children under the age of 21, or a trustee or other fiduciary of a single trust, estate or single fiduciary account) at a reduced sales charge as determined by aggregating the dollar amount of the new purchase and the current value (at offering price) of all Class A, Class B, and/or Class C Shares of The Alger Family of Funds then held by such person and applying the sales charge applicable to such aggregate. In order to obtain such discount, the purchaser must provide sufficient information at the time of purchase to permit verification that the purchase qualifies for the reduced sales charge. The right of accumulation is subject to modification or discontinuance at any time with respect to all shares purchased thereafter.
Letter of Intent (Class A)
A Letter of Intent (“LOI”) contemplating aggregate purchases of $25,000 or more provides an opportunity for an investor to obtain a reduced Class A sales charge by aggregating investments over a 13-month period, provided that the investor refers to such LOI when placing orders. For purposes of a LOI, the “Purchase Amount” as referred to in the sales charge table in the Prospectus includes purchases by “any person” (as defined above) of all Class A, Class B, and/or Class C Shares of The Alger Family of Funds over the following 13 months. An alternative is to compute the 13-month period starting up to 90 days before the date of execution of the LOI.
Purchases made by reinvestment of dividends or distributions of capital gains do not count towards satisfying the amount of the LOI. It is the responsibility of the dealer of record and/or the investor to advise the Distributor about the LOI when placing any purchase orders for the investor during the LOI period. Death or disability of the shareholder will not terminate the LOI.
The minimum initial investment under the LOI is 5% of the total LOI amount. Each investment in Class A Shares made during the period receives the reduced sales charge applicable to the total amount of the investment goal. Shares purchased with the first 5% of the total LOI amount will be held in escrow by the Transfer Agent to assure any necessary payment of a higher applicable sales charge if the investment goal is not met. If the goal is not achieved within the period, the investor must pay the difference between the sales charges applicable to the purchases made and the charges previously paid, or an appropriate number of escrowed shares will be redeemed.
Redemptions
The right of redemption of shares of the Funds may be suspended or the date of payment postponed for more than seven days (a) for any periods during which the NYSE is closed (other than for customary weekend and holiday closings), (b) when trading in the markets the Fund normally utilizes is restricted, or an emergency, as defined by the rules and regulations of the SEC, exists, making disposal of the Fund’s investments or determination of its net asset values not reasonably practicable or (c) for such other periods as the SEC by order may permit for protection of the Fund’s shareholders.
No interest will accrue on amounts represented by uncashed distribution or redemption checks.
27

Telephone Redemptions
Direct investors automatically have the ability to make redemptions by telephone unless you refuse the telephone redemption privilege. To sell shares by telephone, please call (800) 992-3863. Redemption requests received prior to the close of business of the NYSE (normally 4:00 p.m. Eastern time) will generally be mailed on the next business day. Shares issued in certificate form are not eligible for this service.
Redemption proceeds are mailed to the address of record. Any request for redemption proceeds to be sent to the address of record must be in writing with the signature(s) guaranteed if made within 30 days of changing your address.
The Trust, the Transfer Agent and their affiliates are not liable for acting in good faith on telephone instructions relating to your account, so long as they follow reasonable procedures to determine that the telephone instructions are genuine. Such procedures may include recording the telephone calls and requiring some form of personal identification. You should verify the accuracy of telephone transactions immediately upon receipt of your confirmation statement.
Redemptions in Kind
Payment for shares tendered for redemption is ordinarily made in cash. However, the Board has adopted procedures which provide that if the Board determines that it would be detrimental to the best interest of the remaining shareholders of a Fund to make payment of a redemption order wholly in cash, the Fund may pay the redemption proceeds in whole or in part by a distribution “in kind” of securities from the Fund, in lieu of cash, in conformity with applicable rules of the SEC. The Trust has elected to be governed by Rule 18f-1 under the 1940 Act, pursuant to which a Fund is obligated to redeem shares solely in cash up to the lesser of $250,000 or 1% of the net assets of the Fund during any 90-day period for any one shareholder. If shares are redeemed in kind, the redeeming shareholder might incur brokerage or other costs in selling the securities for cash. The method of valuing securities for the purposes of making in-kind redemptions will be the same as the method the Fund generally uses to value its portfolio securities and such valuation will be made as of the time the redemption price is determined. If the Fund pays large redemptions in cash, these transactions may increase the Fund’s transaction costs and detract from the Fund’s performance. Large purchases pose similar risks.
Contingent Deferred Sales Charge (Class A and C)
Certain Class A Shares are subject to a CDSC. Those Class A Shares (as well as when combined with all other Class A Shares of The Alger Family of Funds) purchased in an amount of $1 million or more which have not been subject to the class’s initial sales charge and which have not been held for a full year may be subject to a CDSC of 1% at the time of redemption.
Class C Shares are subject to a CDSC of 1% if redeemed within one year of purchase.
For purposes of the CDSC, it is assumed that the shares of the Focus Equity Fund from which the redemption is made are the shares of the Fund which result in the lowest charge, if any.
Redemptions of shares of the Fund are deemed to be made first from amounts, if any, to which a CDSC does not apply. There is no CDSC on redemptions of (i) amounts that represent appreciation on your original investment, or (ii) shares purchased through reinvestment of dividends and capital gains.
Waivers of Sales Charges (Class A and C)
No initial sales charge is imposed on purchases of Class A Shares, and no CDSC is imposed on redemptions of Class A and C Shares by:
employees of the Distributor and its affiliates,
Individual Retirement Accounts (“IRAs”), Keogh Plans and employee benefit plans for those employees and
spouses, children, siblings and parents of those employees and trusts of which those individuals are beneficiaries, as long as orders for the shares on behalf of those individuals and trusts were placed by the employees;
accounts managed by the Manager,
employees, participants and beneficiaries of those accounts,
28

IRAs, Keogh Plans and employee benefit plans for those employees, participants and beneficiaries and
spouses and minor children of those employees, participants and beneficiaries as long as orders for the shares were placed by the employees, participants and beneficiaries;
directors or trustees of any investment company for which the Distributor or any of its affiliates serves as investment adviser or distributor;
employee benefit or retirement plans or charitable accounts, including, but not limited to, Individual Retirement Accounts, Keogh Plans, 401(k) plans, profit-sharing pension plans, defined benefit plans, Taft-Hartley multiemployer pension plans, 457 plans, 403(b) plans, non-qualified deferred compensation plans, and other defined contribution plans subject to the Employee Retirement Income Security Act of 1974, as amended, other than employee benefit or retirement plans or charitable accounts that purchase Class A Shares through brokerage relationships in which sales charges are customarily imposed;
an investment company registered under the Investment Company Act of 1940, as amended, in connection with the combination of the investment company with the Fund by merger, acquisition of assets or by any other transaction;
registered investment advisers for their own accounts;
certain registered investment advisers, banks, trust companies and other financial institutions (including broker-dealers) that have an agreement in place with the Distributor (see Appendix A — Waivers and Discounts Available from Intermediaries in the Prospectus for a list of such entities), as long as the orders for the shares were placed on behalf of their clients;
certain financial intermediaries offering self-directed investment brokerage accounts that have an agreement in place with the Distributor (see Appendix A — Waivers and Discounts Available from Intermediaries in the Prospectus for a list of such entities);
a financial institution as shareholder of record on behalf of:
investment advisers or financial planners trading for their own accounts or the accounts of their clients, and who charge a separate fee for their services, and
clients of such investment advisers or financial planners trading for their own accounts if the accounts are linked to the master account of such investment adviser or financial planner on the books and records of the financial institution;
a financial institution as shareholder of record on behalf of retirement and deferred compensation plans and trusts used to fund those plans;
registered representatives of broker-dealers that have an agreement in place with the Distributor, for their own accounts and their spouses, children, siblings and parents;
children or spouses of individuals who died in the terrorist attacks of September 11, 2001 made directly at the Fund;
shareholders of Alger Global Focus Fund as of January 21, 2005 purchasing Class A Shares directly from the Fund for their existing accounts;
investors purchasing Class A Shares of the Alger Family of Funds when those purchases are made directly from the Fund (including shareholders of Class N Shares as of September 23, 2008); and
investors purchasing Class A Shares directly from the Fund which, when combined with current holdings of Class A Shares of the Alger Family of Funds offered with a sales charge, equal or exceed $1,000,000 in the aggregate, when such Class A Shares are redeemed within 12 months of purchase.
Investors purchasing Class A Shares who may be entitled to one of the foregoing waivers should consult with their financial advisers as to their eligibility, and are required to claim and substantiate their eligibility for the waiver at the time of purchase. It is also the responsibility of shareholders redeeming shares otherwise subject to a CDSC but qualifying for a waiver of the charge to assert this status at the time of redemption. The Distributor has no information regarding the nature of the underlying
29

shareholders in an omnibus account (in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, a common form of holding shares among retirement plans and financial intermediaries such as brokers, advisers and third-party administrators) it cannot aid in the substantiation of any such claims for waivers. Information regarding these procedures is available by contacting the Funds at (800) 992-3863.
Certain Waivers of the Contingent Deferred Sales Charge (Class A and C)
Any CDSC which otherwise would be imposed on redemptions of Focus Equity Fund shares will be waived with respect to (a) redemptions of shares held at the time a shareholder becomes disabled or dies, including the shares of a shareholder who owns the shares with his or her spouse as joint tenants with right of survivorship, provided that the redemption is requested within one year after the death or initial determination of disability, (b) redemptions in connection with the following retirement plan distributions: (i) lump-sum or other distributions from a qualified corporate or Keogh retirement plan following retirement, termination of employment, death or disability (or in the case of a five percent owner of the employer maintaining the plan, following attainment of age 70½); (ii) required distributions from an Individual Retirement Account (“IRA”) following the attainment of age 70½ or from a custodial account under Section 403(b)(7) of the Internal Revenue Code of 1986, as amended, following the later of retirement or attainment of age 70½; and (iii) a tax-free return of an excess contribution to an IRA, (c) systematic withdrawal payments, and (d) redemptions by the Trust of Fund shares whose value has fallen below the minimum initial investment amount. For purposes of the waiver described in (a) above, a person will be deemed “disabled” if the person is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or to be of long-continued and indefinite duration.
Shareholders claiming a waiver must assert their status at the time of redemption.
Systematic Withdrawal Plan (Class A and C)
A systematic withdrawal plan (the “Withdrawal Plan”) is available to shareholders who own shares of the Focus Equity Fund with a value exceeding $10,000 and who wish to receive specific amounts of cash periodically. Withdrawals of at least $50 monthly (but no more than one percent of the value of a shareholder’s shares in the Fund) may be made under the Withdrawal Plan by redeeming as many shares of the Fund as may be necessary to cover the stipulated withdrawal payment. To the extent that withdrawals exceed dividends, distributions and appreciation of a shareholder’s investment in the Fund, there will be a reduction in the value of the shareholder’s investment and continued withdrawal payments may reduce the shareholder’s investment and ultimately exhaust it. Withdrawal payments should not be considered as income from investment in the Fund.
Shareholders who wish to participate in the Withdrawal Plan and who hold their shares in certificated form must deposit their share certificates of the Fund from which withdrawals will be made with the Transfer Agent, as agent for Withdrawal Plan members. All dividends and distributions on shares in the Withdrawal Plan are automatically reinvested at net asset value in additional shares of the Fund. For additional information regarding the Withdrawal Plan, contact the Fund.
Signature Guarantees
The Transfer Agent has adopted standards and procedures pursuant to which Medallion Signature Guarantees in proper form generally will be accepted from domestic banks, brokers, dealers, credit unions, and national securities exchanges, that are participants in the New York Stock Exchange Medallion Signature Program (MSP), the Securities Transfer Agents Medallion Program (STAMP), and the Stock Exchanges Medallion Program (SEMP).
Exchanges
Except as noted below, shareholders may exchange some or all of their Fund shares for shares of the same class of another fund in The Alger Family of Funds. One class of shares may not be exchanged for another class of shares, except that in limited circumstances certain accounts will be permitted an exchange from one class to another, including, but not limited to, from Class A Shares to Class I or Class Z Shares, or from Class C Shares to Class A, Class I, or Class Z Shares. Once an initial sales charge has been imposed on a purchase of Class A Shares, no additional charge is imposed in connection with their exchange. No CDSC is assessed in connection with exchanges of the same class; however, the original CDSC holding period will carry over to the acquired shares.
30

An exchange from one Fund to another Fund is generally a taxable event, and may generate capital gains or losses for federal income tax purposes. The exchange of shares of one class of a Fund into shares of another class of the same Fund, however, is generally not taxable for federal income tax purposes and no gain or loss will be reported on the transaction. Shareholders are advised to consult with their own tax advisers with respect to the particular tax consequences of an exchange.
Investors who hold shares directly automatically have the ability to make exchanges by telephone unless you refuse the telephone exchange privilege. Exchanges can be made among funds of the same class of shares for identically registered accounts. For tax purposes, an exchange of shares is treated as a sale of the shares exchanged and, therefore, you may realize a taxable gain or loss when you exchange shares.
The Trust reserves the right to terminate or modify the exchange privilege upon notice to shareholders.
Management
Trustees and Officers of the Trust
The Trust is governed by the Board which is responsible for protecting the interests of shareholders under Massachusetts law.
The Board has two standing committees: an Audit Committee and a Nominating Committee. The Audit Committee oversees (a) each Fund’s accounting and financial reporting policies and practices and its internal controls and (b) the quality and objectivity of each Fund’s financial statements and the independent audit thereof. The members of the Audit Committee are Stephen E. O’Neil, Nathan E. Saint-Amand and Charles F. Baird, Jr. The Audit Committee met five times during the Trust’s last fiscal year. The function of the Nominating Committee is, among other things, to select and nominate all candidates for election as Independent Trustees to the Board. The Nominating Committee, which met once during the Trust’s last fiscal year, is composed of all the Independent Trustees.
While the Nominating Committee expects to be able to identify a sufficient number of qualified candidates on its own, it will consider nominations from shareholders that are submitted in writing to the Secretary of the Trust, c/o Fred Alger Management, LLC, 100 Pearl Street, 27th Floor, New York, New York 10004. Any submission should include the following information as to each individual proposed for election or re-election as Trustee: the name, age, business address, residence address and principal occupation or employment of such individual, the class, series and number of shares of stock of the Fund that are beneficially owned by such individual, the date such shares were acquired and the investment intent of such acquisition, whether such shareholder believes such individual is, or is not, an “interested person” (as defined in the 1940 Act) of the Trust, and information regarding such individual that is sufficient, in the discretion of the Nominating Committee, to make such determination, and all other information relating to such individual that is required to be disclosed in a solicitation of proxies for election of Trustees of a registered investment company in an election contest pursuant to Regulation 14A under the Securities Exchange Act (including such individual’s written consent to being named in a proxy statement as a nominee and to serving as a Trustee (if elected)). Any such submission must also be submitted by such date and contain such information as may be specified in the Trust’s By-laws.
Board’s Risk Oversight Role
Risk oversight is part of the Board’s general oversight of the Trust. As is the case with virtually all investment companies (as distinguished from operating companies), service providers to the Trust, primarily the Manager, have responsibility for the day-to-day management of the Funds, which includes responsibility for risk management (including management of investment performance and investment risk, valuation risk, liquidity risk, issuer and counterparty credit risk, compliance risk and operational risk). As part of its oversight, the Board, acting at its scheduled meetings, regularly interacts with and receives reports from senior personnel of service providers, including the Manager’s Chief Investment Officer (or a senior representative of his office) and portfolio management personnel, which include reports on the investment performance of the Funds. In accordance with Rule 22e-4 under the 1940 Act, the Board approved a liquidity risk management program (the “LRMP”), which provides the framework for evaluating the liquidity of the Funds’ investments. The Board, including a majority of the Independent Trustees, appointed the Manager as the administrator of the LRMP, and reviews, no less frequently than annually, a written report prepared by the Manager as the administrator of the LRMP that addresses the operation of the program and assesses its adequacy and effectiveness of implementation. The Board also receives regular liquidity reports. The Board receives regular compliance reports prepared by the Trust’s
31

and the Manager’s Chief Compliance Officer and meets regularly with the Chief Compliance Officer to discuss various compliance matters, including compliance risks. In accordance with SEC rules, the Independent Trustees meet regularly in executive session with the Trust’s and the Manager’s Chief Compliance Officer, and the Chief Compliance Officer prepares and presents an annual written compliance report to the Board. The Board’s Audit Committee (which consists of three Independent Trustees) meets during its scheduled meetings, and between meetings the Audit Committee chair maintains contact with the Trust’s independent registered public accounting firm and the Trust’s Chief Financial Officer.
The Board also receives periodic presentations from senior personnel of the Manager regarding risk management generally, as well as periodic presentations regarding specific operational, compliance or investment areas such as business continuity, anti-money laundering, personal trading, valuation (including information with respect to any fair valued securities), credit, investment research and securities lending. The Board also may receive special reports or presentations on a variety of risk matters, either upon the Board’s request or upon the initiative of the Manager. The Board receives reports from counsel to the Trust or counsel to the Manager and the Board’s own independent legal counsel regarding regulatory compliance and governance matters. The Board’s oversight role does not make the Board a guarantor of the Funds’ investment activities.
Board Composition and Leadership Structure
The 1940 Act requires that at least 40% of the Trust’s trustees be Independent Trustees and as such not be affiliated with the Manager. To rely on certain exemptive rules under the 1940 Act, a majority of the Trust’s trustees must be Independent Trustees, and for certain important matters, such as the approval of investment advisory agreements or transactions with affiliates, the 1940 Act or the rules thereunder require the approval of a majority of the Independent Trustees. Currently, 83% of the Trust’s Trustees, including the Chairman of the Board, are Independent Trustees. The Chairman of the Board chairs Board meetings and executive sessions of the Independent Trustees, reviews and comments on Board meeting agendas, represents the views of the Independent Trustees to management and facilitates communication among the Independent Trustees and their counsel. The Board has determined that its leadership structure, in which the Chairman of the Board is not affiliated with the Manager, is appropriate in light of the services that the Manager provides to the Trust and potential conflicts of interest that could arise from this relationship.

(1)
The address of each Trustee is c/o Fred Alger Management, LLC, 100 Pearl Street, 27th Floor, New York, NY 10004.
(2)
Ms. Alger is an “interested person” (as defined in the 1940 Act) of the Trust by virtue of her ownership control of Alger Associates, Inc. (“Alger Associates”), which controls Alger Management and its affiliates.
(3)
“Alger Fund Complex” refers to the Trust and the five other registered investment companies managed by Alger Management. Each Trustee serves until an event of termination, such as death or resignation, or until his or her successor is duly elected. Each of the Trustees serves on the board of trustees of the other five registered investment companies in the Alger Fund Complex.
Information About Each Trustee’s Experience, Qualifications, Attributes or Skills
The Board believes that the significance of each Trustee’s experience, qualifications, attributes or skills is an individual matter (meaning that experience that is important for one Trustee may not have the same value for another) and that these factors are best evaluated at the board level, with no single Trustee, or particular factor, being indicative of board effectiveness. However, the Board believes that Trustees need to have the skills, experience and judgment necessary to address the issues directors of investment companies confront in fulfilling their duties to fund shareholders. These skills include the ability to critically review, evaluate, question and discuss information provided to them, and to interact effectively with Trust management, service providers and counsel, in order to exercise effective business judgment in the performance of their duties; the Board believes that its members satisfy this standard. Experience relevant to having this ability may be achieved through a Trustee’s educational background; business, professional training or practice (e.g., medicine or law), public service or academic positions; experience from service as a board member (including the Board of the Trust) or as an executive of investment funds, public companies or significant private or not-for-profit entities or other organizations; and/or other life experiences. To assist them in evaluating matters under federal and state law, the Trustees are counseled by their own independent legal counsel, who participates in Board meetings and interacts with the Manager, and also may benefit from information provided by the Trust’s or the Manager’s counsel; both Board and Trust counsel have significant experience advising funds and fund board members. The Board and its committees have the ability to engage other experts as appropriate. The Board evaluates its performance on an annual basis.
Each Trustee has been a Board member of the Alger Fund Complex mutual funds since at least 2007. In addition, the following are among some of the specific experiences, qualifications, attributes or skills that each Trustee possesses (this supplements information provided in the table above), which the Board believes help the Trustees to exercise effective business judgment.

The address of each officer is c/o Fred Alger Management, LLC, 100 Pearl Street, 27th Floor, New York, NY 10004.
(2)
Each officer’s term of office is one year. Each officer serves in the same capacity for the other funds in the Alger Fund Complex.
No director, officer or employee of Alger Management or its affiliates receives any compensation from the Trust for serving as an officer or Trustee of the Trust. Each Independent Trustee receives a fee of $156,000 per annum, paid pro rata based on net assets by each fund in the Alger Fund Complex, plus travel expenses incurred for attending meetings. The Independent Trustee appointed as Chairman of the Board receives an additional compensation of $22,000 per annum paid pro rata based on net assets by each fund in the Alger Fund Complex. Additionally, each member of the Audit Committee receives a fee of $13,000 per annum, paid pro rata based on net assets by each fund in the Alger Fund Complex. It is
34

the current policy of the Trust that Trustees are encouraged, but not required, to invest in the Alger Fund Complex. In furtherance of this objective, effective January 1, 2022, the Trustees adopted a policy requiring Trustees to receive a minimum of 10% of their annual compensation in shares of the funds in the Alger Fund Complex.
Prior to January 1, 2022, each Independent Trustee received a fee of $142,000 per annum, paid pro rata based on net assets by each fund in the Alger Fund Complex, plus travel expenses incurred for attending meetings; the Chairman of the Board received an additional compensation of $20,000 per annum paid pro rata based on net assets by each fund in the Alger Fund Complex; and each member of the Audit Committee received a fee of $13,000 per annum, paid pro rata by each fund in the Alger Fund Complex. Prior to January 1, 2021, each Independent Trustee received a fee of $134,000 per annum, paid pro rata based on net assets by each fund in the Alger Fund Complex, plus travel expenses incurred for attending meetings; the Chairman of the Board received an additional compensation of $20,000 per annum paid pro rata based on net assets by each fund in the Alger Fund Complex; and each member of the Audit Committee received a fee of $13,000 per annum, paid pro rata based on net assets by each fund in the Alger Fund Complex.
The Trustees and officers of the Trust are permitted to purchase shares of the Funds without the payment of any sales charge. Applicable sales charges are waived for these individuals because no selling effort by the Distributor is involved and in order to promote the alignment of such individuals’ economic interests with the Trust.
The Trust did not offer its Trustees any pension or retirement benefits during or prior to the fiscal year ended October 31, 2021. The following table provides compensation amounts paid to current Independent Trustees of the Trust for the fiscal year ended October 31, 2021.

Investment Manager
Alger Management has been in the business of providing investment advisory services since 1964 and, as of December 31, 2021, had approximately $43.8 billion in assets under management. Alger Management is directly owned by Alger Group Holdings, LLC, a financial services holding company. Alger Group Holdings and Alger Management are indirectly controlled by Hilary M. Alger, Nicole D. Alger and Alexandra D. Alger, who own approximately 99% of the voting rights of Alger Associates, the parent company of Alger Group Holdings.
Alger Management serves as investment adviser to the Funds pursuant to a written agreement between the Trust, on behalf of the Funds, and Alger Management (the “Advisory Agreement”), and under the supervision of the Board. The services provided by Alger Management under the Advisory Agreement include: making investment decisions for the Funds, placing orders to purchase and sell securities on behalf of the Funds, and selecting broker-dealers that, in its judgment, provide prompt and reliable execution at favorable prices and reasonable commission rates. Alger LLC may serve as each Fund’s broker in effecting most portfolio transactions on securities exchanges and can retain commissions in accordance with certain regulations of the SEC. Alger Management employs professional securities analysts who provide research services exclusively to the Funds and other accounts for which Alger Management or its affiliates serve as investment adviser or subadviser. Alger Management pays the salaries of all officers of the Trust who are employed by the Trust and Alger Management. Alger Management bears all expenses in connection with the performance of its services under the Advisory Agreement.
As compensation for its services, the Trust has agreed to pay the Manager an investment advisory fee, accrued daily and payable monthly, at the annual rates set forth below as a percentage of the average daily net asset value of the applicable Fund:
Fund
Annual Fee as a Percentage
of Average Daily Net Assets
Alger Capital Appreciation Institutional Fund
.81% for assets up to $2 billion;
.65% for assets between $2 billion and $3 billion;
.60% for assets between $3 billion and $4 billion;
.55% for assets between $4 billion and $5 billion;
.45% for assets in excess of $5 billion
Alger Focus Equity Fund
.52%
Alger Mid Cap Growth Institutional Fund
.76% for assets up to $1 billion;
.70% for assets in excess of $1 billion
Alger Small Cap Growth Institutional Fund
.81% for assets up to $1 billion;
.75% for assets in excess of $1 billion
The Manager has made contractual commitments to certain of the Funds to waive its fee and/or
36

reimburse such Funds for expenses to the extent necessary to maintain those Funds’ total annual operating expenses at or below certain levels. The limitations do not include acquired fund fees and expenses, dividend expense on short sales, borrowing costs, interest, taxes, brokerage and extraordinary expenses, to the extent applicable. Each agreement runs through February 29, 2024 and may only be amended or terminated prior to its expiration date by agreement between the Manager and the Board, and will terminate automatically in the event of termination of the Advisory Agreement. Such waiver/reimbursement arrangements are described in the table below. The Manager may, during the term of the contract, recoup any fees waived or expenses reimbursed pursuant to the contract; however, a Fund will only make repayments to the Manager if such repayment does not cause a Fund’s expense ratio after the repayment is taken into account, to exceed both (i) the expense cap in place at the time such amounts were waived or reimbursed, and (ii) a Fund’s current expense cap. Such recoupment is limited to two years from the date the amount is initially waived or reimbursed.

Description of Portfolio Manager Compensation Structure
An Alger portfolio manager’s compensation generally consists of salary and an annual bonus. In addition, portfolio managers are eligible for health and retirement benefits available to all Alger employees, including a 401(k) plan sponsored by Alger Management. A portfolio manager’s base salary is typically a function of the portfolio manager’s experience (with consideration given to type, investment style and size of investment portfolios previously managed), education, industry knowledge and the individual’s performance in his or her role. Base salaries will grow over time for Alger’s superior employees, rewarding their performance and contributions to the firm.
Bonus may be a significant portion of an individual’s compensation and can vary from year to year. The annual bonus considers various factors, including:
the firm’s overall financial results and profitability;
the firm’s overall investment management performance;
current year’s and prior years’ pre-tax investment performance (both relative and absolute) of the portfolios for which the individual is responsible, based on the benchmark of each such portfolio;
qualitative assessment of an individual’s performance with respect to the firm’s investment process and standards; and
the individual’s leadership contribution within the firm.
While the benchmarks and peer groups used in determining a portfolio manager’s compensation may change from time to time, Alger Management may refer to benchmarks, such as those provided by Russell Investments and S&P Global Ratings, and peer groups, such as those provided by Lipper Inc. and Morningstar Inc., that are widely-recognized by the investment industry.
Alger Management has implemented a profit participation plan (“PPP”) that gives key personnel the opportunity to have equity-like participation in the long-term growth and profitability of the firm. Senior members of the firm are eligible to receive awards annually in the PPP. The PPP reinforces the portfolio managers’ commitment to generating superior investment performance for the firm’s clients. The awards are invested in Alger mutual funds and have a four-year vesting schedule. The total award earned can increase or decrease with the firm’s investment and earnings results over the four-year period.
Additionally, the Alger Partners Plan provides key investment executives with phantom equity that allows participants pro-rata rights to growth in the firm’s book value, dividend payments and participation in any significant corporate transactions (e.g. partial sale, initial public offering, merger, etc.). The firm does not have a limit on the overall percentage of the firm’s value it will convey through this program. Participation in this program is determined annually.

Distributor
Alger LLC, an affiliate of Alger Management, serves as the Funds’ principal underwriter, or distributor, and receives payments from the Funds under the Plans (see “Purchases — Distribution Plans”). Alger LLC makes a continuous offering of Fund shares on a best efforts basis. It also receives brokerage commissions from the Trust (see “Investment Strategies and Policies — Portfolio Transactions”). During the Fund's fiscal years ended October 31, 2019, 2020 and 2021, Alger LLC retained approximately $1,718, $0 and $0 in initial sales charges and $4,062, $7,119 and $6,220 in CDSCs, respectively. Alger LLC does not receive any other compensation from the Funds.
From time to time Alger LLC, at its expense from its own resources, may compensate brokers, dealers, investment advisers or others (“financial intermediaries”) who are instrumental in effecting investments by their clients or customers in the Trust, in an amount up to 1% of the value of those investments. Alger LLC may also from time to time, at its expense from its own resources, make payments to other financial intermediaries that provide shareholder servicing, or transaction processing, with such payments structured as a percentage of gross sales, a percentage of net assets, and/or as a fixed dollar amount (the latter as a per account fee or as reimbursement for transactions processing and transmission charges). Payments under these other arrangements may vary but generally will not exceed 0.50% annually of the value of Trust assets or 0.50% annually of the value of Trust sales attributable to that financial intermediary. Alger LLC determines whether to make any additional cash payments and the amount of any such payments in response to requests from financial intermediaries, based on factors Alger LLC deems relevant. Factors considered by Alger LLC generally include the financial intermediary’s reputation, ability to attract and retain assets for the Trust, expertise in distributing a particular class of shares of the Trust, entry into target markets, and/or quality of service.
Financial intermediaries with whom Alger LLC has its most significant arrangements to make
39

additional cash compensation payments are Ameriprise Financial Services, Inc., Ameritas Investment Corporation, Ameritrade Inc., Charles Schwab & Co, Great-West Life & Annuity Insurance Company, GWFS Equities, Inc., ING America Insurance Holdings INC, Jefferson National Life, Lincoln Benefit Life, LPL Financial Corporation, Merrill Lynch, Pierce, Fenner & Smith, Midland National Life Ins Co, MML Distributors LLC, Morgan Stanley Smith Barney LLC, MSCS Financial Services LLC, National Financial Services Co, Noramco, Oneamerica Securities, Inc., Pershing LLC, Protective Life Insurance Company, Raymond James & Associates, Inc., RBC Capital Markets LLC, Talcott Resolution Life Insurance Co, UBS Financial Services Inc., and Wells Fargo Clearing Services LLC. In addition, Alger LLC may make payments to dealer firms in the form of payments for marketing support, seminar support, training meetings, or comparable expenses in the discretion of Alger LLC. Please contact your financial intermediary for details about revenue sharing payments it may receive. Any payments described above will not change the price paid by investors for the purchase of shares of a Fund or the amount of proceeds received by a Fund on the sale of shares.
Independent Registered Public Accounting Firm
Deloitte & Touche LLP serves as the Trust’s independent registered public accounting firm.
Code of Ethics
Alger Management personnel (“Access Persons”) are permitted to engage in personal securities transactions, including transactions in securities that may be purchased or held by the Funds, subject to the restrictions and procedures of the Trust’s Code of Ethics. Pursuant to the Code of Ethics, Access Persons generally must pre-clear all personal securities transactions prior to trading and are subject to certain prohibitions on personal trading. You can obtain a copy of the Trust’s Code of Ethics by calling the Trust toll-free at (800) 992-3863.
Certain U.S. Federal Income Tax Considerations
The following is a summary of selected federal income tax considerations that may affect the Trust and its shareholders. The summary is not intended to substitute for individual tax advice and investors are urged to consult their own tax advisers as to the federal, state and local tax consequences of investing in the Funds.
Each Fund will be treated as a separate taxpayer with the result that, for federal income tax purposes, the amounts of net investment income and capital gains earned will be determined on a Fund-by-Fund (rather than on a Trust-wide) basis.
Each Fund intends to qualify as a “regulated investment company” under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). If qualified as a regulated investment company, a Fund will pay no federal income taxes on its investment company taxable income (that is, taxable income other than net realized long-term capital gains) and its net realized long-term capital gains that are distributed to shareholders. To qualify under Subchapter M, a Fund must, among other things: (1) distribute to its shareholders at least 90% of its taxable net investment income and net realized short-term capital gains; (2) derive at least 90% of its gross income from dividends, interest, payments with respect to loans of securities, gains from the sale or other disposition of securities, or other income (including, but not limited to, gains from options, futures and forward contracts) derived with respect to the Fund’s business of investing in securities; and (3) diversify its holdings so that, at the end of each fiscal quarter of the Fund (a) at least 50% of the market value of the Fund’s assets is represented by cash, U.S. Government securities and other securities, with those other securities limited, with respect to any one issuer, to an amount no greater in value than 5% of the Fund’s total assets and to not more than 10% of the outstanding voting securities of the issuer, and (b) not more than 25% of the market value of the Fund’s assets is invested in the securities of any one issuer (other than U.S. Government securities or securities of other regulated investment companies) or of two or more issuers that the Fund controls and that are determined to be in the same or similar trades or businesses or related trades or businesses. In meeting these requirements, a Fund may be restricted in the utilization of certain of the investment techniques described above and in the Prospectuses. As a regulated investment company, each Fund is subject to a non-deductible excise tax of 4% with respect to certain undistributed amounts of income and capital gains during the calendar year. The Trust expects each Fund to make additional distributions or change the timing of its distributions so as to avoid the application of this tax. Although the Trust expects
40

each Fund to make such distributions as are necessary to avoid the application of this tax, certain of such distributions, if made in January, might be included in the taxable income of shareholders in the year ended in the previous December.
Payments reflecting the dividend income of a Fund will not qualify for the dividends-received deduction for corporations if the Fund sells the underlying stock before satisfying a 46-day holding period requirement (91 days for certain preferred stock). Dividends-received deductions will be allowed to a corporate shareholder only if similar holding period requirements with respect to shares of the Fund have been met.
In general, any gain or loss on the redemption or exchange of Fund shares will be long-term capital gain or loss if held by the shareholder for more than one year, and will be short-term capital gain or loss if held for one year or less. However, if a shareholder receives a distribution taxable as long-term capital gain with respect to Fund shares, and redeems or exchanges the shares before holding them for more than six months, any loss on the redemption or exchange up to the amount of the distribution will be treated as a long-term capital loss.
Dividends of a Fund’s net investment income and distributions of its short-term capital gains will generally be taxable as ordinary income. Distributions of long-term capital gains will be taxable as such at the appropriate rate, regardless of the length of time you have held shares of the Fund.
If a Fund is the holder of record of any stock on the record date for any dividends payable with respect to such stock, such dividends are included in the Fund’s gross income as of the later of (a) the date such stock became ex-dividend with respect to such dividends (i.e., the date on which a buyer of the stock would not be entitled to receive the declared, but unpaid, dividends) or (b) the date the Fund acquired such stock. Accordingly, in order to satisfy its income distribution requirements, a Fund may be required to pay dividends based on anticipated earnings and shareholders may receive dividends in an earlier year than would otherwise be the case.
Investors considering buying shares of a Fund just prior to a record date for a taxable dividend or capital gain distribution should be aware that, regardless of whether the price of the Fund shares to be purchased reflects the amount of the forthcoming dividend or distribution payment, any such payment will be a taxable dividend or distribution payment.
If a shareholder fails to furnish a correct taxpayer identification number, fails to fully report dividend or interest income, or fails to certify that he or she has provided a correct taxpayer identification number and that he or she is not subject to such withholding, then the shareholder may be subject to a 28 percent “backup withholding tax” with respect to (i) any taxable dividends and distributions and (ii) any proceeds of any redemption of Fund shares. An individual’s taxpayer identification number is his or her social security number. The 28 percent backup withholding tax is not an additional tax and may be credited against a shareholder’s regular federal income tax liability.
Shortly after the close of each calendar year, you will receive a statement setting forth the dollar amounts of dividends and any distributions for the prior calendar year and the tax status of the dividends and distributions for federal income tax purposes. You should consult your tax adviser to assess the federal, state and local tax consequences of investing in each Fund. This discussion is not intended to address the tax consequences of an investment by a nonresident alien.
The foregoing is a general and abbreviated summary of the applicable provisions of the Code and Treasury regulations presently in effect. For the complete provisions, reference should be made to the pertinent Code sections and the Treasury regulations promulgated thereunder. Plan participants should consult their plan sponsors or tax advisers regarding the tax consequences of participation in the plan or of any plan contributions or withdrawals.
Dividends
Each share class will be treated separately in determining the amounts of dividends or investment income and distributions of capital gains payable to holders of its shares. Dividends and distributions will be automatically reinvested at net asset value on the payment date in additional shares of the class that paid the dividend or distribution at net asset value, unless you elected to have all dividends and distributions paid in cash or reinvested at net asset value into the same class of shares of another identically registered Alger Family of Funds account you have established. In addition, accounts whose
41

dividend/distribution checks have been returned as undeliverable shall reinvest that dividend/distribution at the net asset value next determined after the Transfer Agent receives the undelivered check. Furthermore, all future dividend/distribution checks shall be reinvested automatically at net asset value on the payment date until a written request for reinstatement of cash distribution and a valid mailing address are provided by the share-holder(s). Shares purchased through reinvestment of dividends and distributions are not subject to a CDSC or front-end sales charge except as described above. Dividends will be declared and paid annually. Distributions of any net realized short-term and long-term capital gains earned by a Fund usually will be made annually after the close of the fiscal year in which the gains are earned.
The classes of a Fund may have different dividend and distribution rates. Class A and Class I dividends generally will be greater than those of Class C and Class R due to the higher expenses borne by Class C and Class R Shares. Class Y, Class Z and Class Z-2 dividends will generally be greater than those of the other classes due to lower expenses. However, dividends paid to each class of shares in a Fund will be declared and paid at the same time and will be determined in the same manner as those paid to each other class.
Custodian and Transfer Agent
Brown Brothers Harriman & Co., 50 Post Office Square, Boston, Massachusetts 02110 serves as custodian for the Trust pursuant to a custodian agreement under which it holds each Fund’s assets. UMB Fund Services, Inc. (“UMB”), 235 W. Galena Street, Milwaukee, WI 53212 serves as transfer agent for the Funds. Prior to October 7, 2019, DST Asset Manager Solutions, Inc. served as transfer agent for the Funds. Under the transfer agency agreement, UMB processes purchases and redemptions of shares of the Funds, maintains the shareholder account records for each Fund, handles certain communications between shareholders and the Trust, and distributes any dividends and distributions payable by the Funds. The Trust, Alger LLC (or its affiliates) and non-affiliated third-party service providers may enter into agreements for recordkeeping services.
Pursuant to the transfer agency agreement, UMB is compensated on a per-account basis, subject to a minimum total fee amount across the fund complex. These fees will be allocated across the Funds on a pro-rata basis by assets. The Trust has entered into a Shareholder Administrative Services Agreement with Alger Management to act as a liaison and to provide administrative oversight of UMB and related services. Alger Management is paid on an asset-based basis for these services. During the fiscal years ended October 31, 2019, 2020, and 2021, the Funds paid to Alger Management under the Shareholder Administrative Services Agreement:

Principal Holders
A principal shareholder is any person who owns (either of record or beneficially) 5% or more of any class of outstanding shares of a Fund. A person who beneficially owns, either directly or indirectly, more than 25% of the voting securities of a Fund or acknowledges the existence of such control may be presumed to control the Fund. A control person could potentially control the outcome of any proposal submitted to the shareholders for approval, including changes to a Fund’s fundamental policies or terms of the Advisory Agreement. Certain of the investors below are believed to hold the indicated shares as nominee.
Additionally, the Manager or an affiliate of the Manager (the “seed investor”) may provide initial funding to or otherwise invest in a Fund. A seed investor may redeem its investment in a Fund at any time and without prior notice, which could adversely affect a Fund and its shareholders, such as by causing the Fund to realize taxable gains that will be distributed to other shareholders, and increasing Fund transaction costs and expense ratios.
The following table contains information regarding persons of record who own five percent or more of any share class of the Fund. All holdings are expressed as a percentage of a class of the Fund’s
42

outstanding shares as of January 31, 2022.
Unless otherwise indicated, a Fund has no knowledge as to whether all or any portion of the shares owned of record are also owned beneficially. The Trustees and officers of the Trust, as a group, held directly less than 1% of each Class of Shares of the Funds.

Organization
The Trust has been organized as an unincorporated business trust under the laws of the Commonwealth of Massachusetts pursuant to an Agreement and Declaration of Trust dated July 14, 1993 (the “Trust Agreement”) under the name The Alger Defined Contribution Trust. The Trust offers shares of beneficial interest of separate series, par value $.001 per share. An unlimited number of shares of four series, representing the shares of the Funds, have been authorized. The word “Alger” in the Trust’s name has been adopted pursuant to a provision contained in the Agreement and Declaration of Trust. Under that provision, Alger Management may terminate the Trust’s license to use the word “Alger”
48

in its name when Alger Management ceases to act as the Trust’s investment manager.
On February 25, 2002, the names of the Trust and its portfolios were changed to The Alger Institutional Fund, and Alger Capital Appreciation Institutional Portfolio, Alger LargeCap Growth Institutional Portfolio, Alger MidCap Growth Institutional Portfolio and Alger SmallCap Institutional Portfolio. On January 27, 2003, Class R Shares were added to all of the Trust’s portfolios. The previously existing shares were designated Class I Shares on that date. Shares of each portfolio are thus divided into two classes, Class I and Class R, except that Focus Equity Fund has also offered Class A, C and Z Shares since December 31, 2012. Class R Shares of Focus Equity Fund were terminated on November 25, 2013. The classes differ in that (a) each class has a different class designation; (b) the Class A Shares are subject to initial sales charges; (c) the Class C Shares are subject to CDSCs, and certain Class A Shares may also be subject to a CDSC; (d) each of Class A, C and R Shares are subject to different distribution and/or service fees under a plan adopted pursuant to rule 12b-1 under the 1940 Act; (e) Class I and R Shares are subject to a service fee; (f) Class Y, Z and Z-2 Shares are not subject to distribution and/or service fees; (g) to the extent that one class alone is affected by a matter submitted to a shareholder vote, then only that class has voting power on the matter; and (h) the exchange privileges and conversion rights of each class differ from those of the others. On February 24, 2004, the names of the Trust and its portfolios were changed to The Alger Institutional Funds, and Alger Capital Appreciation Institutional Fund, Alger LargeCap Growth Institutional Fund, Alger MidCap Growth Institutional Fund and Alger SmallCap Growth Institutional Fund. On March 1, 2010, the names of the portfolios were changed to their current names, except that on December 31, 2012, Alger Large Cap Growth Institutional Fund became Alger Capital Appreciation Focus Fund. On October 15, 2018, Alger Capital Appreciation Focus Fund changed its name to Alger Focus Equity Fund. Class Z-2 Shares of Alger Small Cap Growth Institutional Fund were offered on August 1, 2016. Class Z-2 Shares of Alger Capital Appreciation Institutional Fund and Alger Mid Cap Growth Institutional Fund were offered on October 14, 2016. The Alger Institutional Funds began offering Class Y Shares on February 28, 2017.
The Trust is an open-end management investment company. Each Fund is classified as a “diversified” investment company under the 1940 Act. Accordingly, each Fund is required, with respect to 75% of its assets, to limit its investment in one issuer (other than the U.S. government and other investment companies) to no more than 5% of the investment company’s total assets. Each Fund intends to continue to qualify as a “regulated investment company” under the Internal Revenue Code; one of the requirements for such qualification is a quarterly diversification test, applicable to 50% (rather than 75%) of the Fund’s assets, similar to the requirement stated above.
Shares do not have cumulative voting rights, which means that holders of more than 50% of the shares voting for the election of Trustees can elect all Trustees. Shares have equal voting rights, which cannot be adversely modified other than by majority vote. Shares are transferable but have no preemptive, conversion or subscription rights, except that Class C Shares automatically convert to Class A Shares after specified periods. Shareholders generally vote by Fund, except with respect to the election of Trustees and the ratification of the selection of independent accountants, and by class within a Fund on matters in which the interests of one class differ from those of another. In the interest of economy and convenience, certificates representing shares of a Fund are physically issued only upon specific written request of a shareholder.
The Class A, C, I, R, Y, Z and Z-2 Shares differ in that: (a) each class has a different class designation; (b) the Class A Shares are subject to initial sales charges; (c) the Class C Shares are subject to CDSCs, and certain Class A Shares may also be subject to a CDSC; (d) each of Class A, C and R Shares are subject to different distribution and/or service fees under the Plans; (e) each of Class I and R Shares are subject to a shareholder servicing fee under the Shareholder Servicing Agreement, (f) Class Y, Z and Z-2 Shares are not subject to distribution and/or service fees; (g) to the extent that one class alone is affected by a matter submitted to a vote of the shareholders, then only that class has voting power on the matter; and (h) the exchange privileges and conversion rights of each class differ from those of the others.
Although, as a Massachusetts business trust, the Trust is not required by law to hold annual shareholder meetings, it may hold meetings from time to time on important matters, and shareholders have the right to call a meeting to remove a trustee or to take other action described in the Trust’s Declaration of Trust.
Meetings of shareholders normally will not be held for the purpose of electing Trustees unless and until such time as less than a majority of the Trustees holding office have been elected by shareholders, at which time the Trustees then in office will call a shareholders’ meeting for the election of Trustees. Under
49

the 1940 Act, shareholders of record of no less than two-thirds of the outstanding shares of the Trust may remove a Trustee through a declaration in writing or by vote cast in person or by proxy at a meeting called for that purpose. Under the Trust Agreement, the Trustees are required to call a meeting of shareholders for the purpose of voting on the question of removal of any such Trustee when requested in writing to do so by the shareholders of record of not less than 10% of the Trust’s outstanding shares.
Massachusetts law provides that shareholders could, under certain circumstances, be held personally liable for the obligations of the Trust. However, the Trust Agreement disclaims shareholder liability for acts or obligations of the Trust and requires the Trustees to use their best efforts to ensure that notice of such disclaimer be given in each agreement, obligation or instrument entered into or executed by the Trust or a Trustee. The Trust Agreement provides for indemnification from the Trust’s property for all losses and expenses of any shareholder held personally liable for the obligations of the Trust. Thus, the risk of a shareholder’s incurring financial loss on account of shareholder liability is limited to circumstances in which the Trust itself would be unable to meet its obligations, a possibility that the Trust believes is remote.
Upon payment of any liability incurred by the Trust, the shareholder paying the liability will be entitled to reimbursement from the general assets of the Trust. The Trustees intend to conduct the operations of the Trust in a manner so as to avoid, as far as possible, ultimate liability of the shareholders for liabilities of the Trust.
The Trust is an open-end management investment company. Each of the Funds is classified as a “diversified” investment company under the 1940 Act. A “diversified” investment company is required, with respect to 75% of its assets, to limit its investment in any one issuer (other than the U.S. government and other investment companies) to no more than 5% of the investment company’s total assets. Each Fund intends to continue to qualify as a “regulated investment company” under Subchapter M of the Internal Revenue Code; one of the requirements for such qualification is a quarterly diversification test, applicable to 50% (rather than 75%) of a Fund’s assets, similar to the requirement stated above.
Proxy Voting Policies and Procedures
The Board has delegated authority to vote all proxies related to the Funds’ portfolio securities to Alger Management, the Funds’ investment manager. Alger Management, an investment adviser registered under the Investment Advisers Act of 1940, as amended, maintains discretionary authority over client accounts, including the Funds, and is responsible for voting proxies of all foreign and domestic securities held in the Funds. Alger Management views the responsibility its clients have entrusted to it seriously and has adopted and implemented written policies and procedures designed to ensure that proxies are voted in the best interests of its clients.
Alger Management receives and considers the recommendations of Institutional Shareholder Services Inc. (“ISS”), a leading proxy voting service provider and registered investment adviser. ISS issues voting recommendations and casts votes on the proxies based on pre-determined proxy voting guidelines intended to vote proxies in the clients’ best interests, which are summarized below. To the extent ISS has a material conflict of interest with the company whose proxies are at issue, ISS may recuse itself from voting proxies. Alger Management monitors ISS’s proxy voting policies and procedures on a quarterly basis to ensure that the proxies are voted in the best interests of the applicable Fund. Further, Alger Management has a process in place for making voting determinations in the event of a conflict of interest.
Alger Management maintains records of its proxy voting policies and procedures. Alger Management or ISS, on Alger Management’s behalf, maintains proxy statements received regarding securities held by the Funds; records of votes cast on behalf of each Fund; records of requests for proxy voting information; and any documents prepared that were material to making a voting decision.
No later than August 31st each year, the Funds proxy voting record for the most recent 12 months ended June 30th will be available upon request by calling (800) 992-3863 and on the Funds website and on the SEC’s website at http://www.sec.gov.
The following is a summary of the two sets of voting guidelines used (as applicable) by Alger Management, or ISS on Alger Management’s behalf, to vote proxies of securities held by the Funds.
Overview of ISS’s Specialty SRI U.S. Proxy Voting Guidelines
ISS’s SRI proxy voting guidelines, like the other Specialty Policy proxy voting guidelines, have been
50

formulated to help institutional investors align their corporate governance philosophies and investment objectives with their proxy voting activities. They have been developed specifically to reflect the perspectives of the SRI investor constituency and are designed to represent the views of related organizations and applicable global initiatives. The ISS SRI guidelines are generally supportive of proposals that promote:
Greater disclosure of corporate environmental policies including climate change and greenhouse gas or toxic emissions;
Greater transparency of social policies such as those concerning workplace discrimination and corporate board diversification efforts, human rights, and compliance with human/labor rights norms/codes of conduct; and
Reporting on sustainable business practices including recycling, wood procurement, water use, operations in sensitive or protected areas, energy efficiency/renewable energy, and incorporation of sustainability-related performance metrics into executive compensation.
In addition, the SRI guidelines are also supportive of the following topics:
Board diversity — recommend votes against nominating committee members when the board lacks diversity (the ISS Benchmark guidelines do not consider diversity when providing recommendations on board members);
ESG risk management — recommend votes against directors individually, on a committee, or potentially the entire board due to material failures of governance, stewardship, risk oversight, or fiduciary responsibilities at the company, including failure to adequately manage or mitigate environmental and social risks (the ISS Benchmark guidelines do not recommend votes against directors for ESG risks);
Auditor independence — recommend votes against auditor ratification when non-audit fees exceed a quarter of total fees paid to auditor (the ISS Benchmark guidelines recommend votes against the auditor ratification when non audit fees exceed half of total fees); and
Environmental stewardship and socially responsible/sustainable business practices.
The SRI guidelines will generally support proxy voting proposals that call for actions beyond disclosure reporting of corporate environmental policies or resolutions seeking greater transparency around social policies and practices — including support for proposals seeking adoption of policies on topics such as human/labor rights, workplace safety or discrimination, access to pharmaceutical drugs, incorporation of sustainability-related performance metrics into executive compensation, hydraulic fracturing and climate change and greenhouse gas or toxic emissions, among others.
The SRI guidelines also have a higher bar when evaluating Management Say-On-Pay proposals (MSOPs) that outline executive compensation programs compared to the ISS Benchmark Policy, with greater emphasis on the strength of alignment between pay and performance when executive pay has outpaced returns to shareholders over short- and long-term periods. The guidelines also place greater scrutiny on pay quantum relative to the firm’s peers as well as with respect to other executive officers within the firm in question, in the context of company performance and the proportion of executive pay that is performance-contingent. A separate document providing more details on the SRI policy’s approach to MSOPs is available.
Further, the SRI guidelines also assess whether any relevant social or environmental metrics are a component of performance-based pay elements in executive pay programs, particularly in instances where significant ESG controversies have been identified that pose potential material risks to the company and its shareholders.
Overview ISS’s Specialty SRI International Proxy Voting Guidelines
ISS’s SRI International proxy voting guidelines, like the other Specialty Policy proxy voting guidelines, have been formulated to help institutional investors align their corporate governance philosophies and investment objectives with their proxy voting activities for international holdings. They have been developed specifically to reflect the perspectives of the SRI investor constituency and are designed to represent the views of related organizations and applicable global initiatives. The ISS SRI International guidelines are generally supportive of proposals that promote:
51

Greater disclosure of corporate environmental policies including climate change and greenhouse gas or toxic emissions;
Greater transparency of social policies such as those concerning workplace discrimination and corporate board diversification efforts, human rights, and compliance with human/labor rights norms/codes of conduct; and
Reporting on sustainable business practices including recycling, wood procurement, water use, operations in sensitive or protected areas, energy efficiency/renewable energy, and incorporation of sustainability-related performance metrics into executive compensation.
In addition, the SRI International guidelines are also supportive of the following topics:
Board diversity — evaluate gender diversity on boards in international markets when reviewing director elections, to the extent that disclosure and market practices permit (the ISS Benchmark guidelines do not consider diversity when providing recommendations on board members);
ESG risk management — recommend votes against directors individually, the relevant committee, or potentially the entire board due to material failures of governance, stewardship, risk oversight, or fiduciary responsibilities at the company, including failure to adequately manage or mitigate environmental and social risks (the ISS Benchmark guidelines do not recommend votes against directors for ESG risks); and
Environmental stewardship and socially responsible/sustainable business practices.
ISS’s Social Advisory Services division recognizes that socially responsible investors have dual objectives: financial and social. Socially responsible investors invest for economic gain, as do all investors, but they also require that the companies in which they invest conduct their business in a socially and environmentally responsible manner. Social Advisory Services has, therefore, developed proxy voting guidelines that are consistent with the dual objectives of socially responsible shareholders. On matters of social and environmental import, the guidelines seek to reflect a broad consensus of the socially responsible investing community. We incorporate the active ownership and investment philosophies of leading globally recognized initiatives such as the United Nations Environment Programme Finance Initiative (UNEP FI), the United Nations Principles for Responsible Investment (UNPRI), the United Nations Global Compact, and environmental and social European Union Directives.
ISS SRI International Proxy Voting Guidelines Background
ISS’s SRI international voting guidelines reflect a broad consensus of the socially responsible investor community in promoting the dual objectives of SRI investors — financial returns and responsible social/environmental conduct by corporations.
The SRI guidelines, which have been in place for more than sixteen years, have been developed in collaboration with our SRI clients and SRI market participants, and are also informed by the active ownership and investment philosophies of globally recognized initiatives such as the UNEP FI, the UN PRI, the UN Global Compact, CERES/Sullivan Principles, and environmental and social European Union Directives, among others.

Summary
Alger Management and Alger LLC, an affiliated registered broker-dealer and a member of the New York Stock Exchange, are owned by Alger Group Holdings, LLC, which is wholly-owned by Alger Associates. Additionally, Alger Management is under common ownership with Weatherbie Capital, LLC, a registered investment adviser based in Boston, Massachusetts. Alger LLC serves as the principal underwriter for the Funds and as a broker-dealer for securities trades placed on behalf of Alger Management clients and accounts. Alger LLC does not conduct public brokerage business and substantially all of its transactions are for clients of Alger Management if their investment guidelines and relevant regulations that govern their accounts allow it. Neither Alger Management nor any of its management personnel is registered or plans to register as a futures commission merchant, commodity pool operator, commodity trading advisor, or an associated person of these entities. From time to time, Alger LLC, Alger Management, Alger Group Holdings, LLC, or Alger Associates, or other affiliated persons (“Alger Affiliates”) may hold controlling positions in certain pooled investment vehicles, such that they are considered affiliates.
In addition to serving as investment adviser of the ETFs and mutual funds in the Alger Family of Funds, Alger Management is the investment adviser to Alger Dynamic Return Fund LLC, a Delaware limited liability company, as well as to Alger SICAV, a publicly offered pooled investment vehicle registered in Luxembourg. Alger Management also serves as a sub-adviser to third-party registered investment companies, as well as bank collective investment trusts. From time to time, Alger Affiliates may own significant stakes in one or more of the above entities.
Alger Management may recommend to clients that they purchase interests in investment partnerships or funds for which Alger Management serves as investment adviser or sub-adviser and in which Alger Management and related persons have a financial interest. Alger Management and such related persons will fully disclose such financial interests to all clients to which such recommendations are given.
Alger Affiliates also have other direct and indirect interests in the equity markets, directly or through investments in pooled products, in which the Funds directly and indirectly invest. Investors should be aware that this may cause Alger Affiliates to have conflicts that could disadvantage the Funds.
As a registered investment adviser under the Investment Advisers Act of 1940, as amended, Alger Management is required to file and maintain a registration statement on Form ADV with the SEC. Form ADV contains information about assets under management, types of fee arrangements, types of investments, conflicts and potential conflicts of interest, and other relevant information regarding Alger Management. Alger Management’s Form ADV is available on the SEC’s website (www.adviserinfo.sec.gov).
Conflicts as a Result of the Manager’s Other Affiliates
Selection of Administrative and Other Service Providers. Alger Management may choose to (and currently does) have Alger Affiliates provide administrative services, shareholder services, brokerage and other account services to the Funds. While any such engagement would be on market terms, it will nevertheless result in greater benefit to Alger Management than hiring a similarly qualified unaffiliated service provider.
In connection with these services and subject to applicable law, Alger Affiliates, including the Manager, may from time to time, and without notice to investors or clients, in-source or outsource certain processes or functions that it provides in its administrative or other capacities. Such in-sourcing or outsourcing may give rise to additional conflicts of interest, including which processes or functions to in-source or outsource, which entity to outsource to, and the fees charged by the Alger Affiliates or the third party. Alger Management maintains policies designed to mitigate the conflicts described herein; however, such policies may not fully address situations described above.
Information the Investment Adviser May Receive. Alger Management and its affiliates may have or be deemed to have access to the current status of certain markets, investments and funds because of Alger Affiliates’ brokerage and other activities. Alger Affiliates may therefore possess information which, if known to Alger Management, might cause Alger Management to seek to dispose of, retain or increase interests in investments held by a Fund, or acquire certain positions on behalf of a Fund. Moreover, Alger Management and its affiliates may come into possession of material, non-public information that would prohibit or otherwise limit its ability to trade on behalf of the Funds. A fund not advised by Alger Management would not be subject to these restrictions. Alger Management maintains policies designed to
53

prevent the disclosure of such information; however, such policies may not fully address situations described above.
Allocation Issues
As Alger Management manages multiple accounts or funds managed or advised by Alger Affiliates (including Alger Management) or in which Alger Affiliates (including Alger Management) or its personnel have interests (collectively, the “client/Alger Affiliates accounts”), issues can and do arise as a result of how Alger Management allocates investment opportunities. In an effort to treat all clients/Alger Affiliates reasonably in light of all factors relevant to managing an account, aggregated trades will generally be allocated pro rata among the Funds and client/Alger Affiliates accounts whenever possible. There are exceptions to this practice, however, as described below:
Unusual Market Conditions. During periods of unusual market conditions, Alger Management may deviate from its normal trade allocation practices. During such periods, Alger Management will seek to exercise a disciplined process for determining its actions to appropriately balance the interests of all accounts, including the Funds, as it determines in its sole discretion.
Availability of Investments. The availability of certain investments such as initial public offerings or private placements may be limited. In such cases, all client/Alger Affiliates accounts (including the Funds) may not receive an allocation. As a result, the amount, timing, structuring or terms of an investment by a Fund may differ from, and performance may be lower than, investments and performance of other client/Alger Affiliates accounts.
Alger Management, as a general practice, allocates initial public offering shares and other limited availability investments pro rata among the eligible client/Alger Affiliates accounts (including the Funds) where the portfolio manager seeks an allocation. An account or accounts may not receive an allocation because it lacks available cash, is restricted from making certain investments, the account pays a performance fee, the account is so large that the allocation is determined to not be meaningful to the account’s overall performance, or due to co-investment by Alger Affiliates. When a pro rata allocation of limited availability investments is not possible or is not appropriate, Alger Management considers numerous other factors to determine an appropriate allocation. These factors include (i) Alger Management’s good faith assessment of the best use of such limited opportunities relative to the account’s investment objectives, investment limitations and requirements of the accounts; (ii) suitability requirements and the nature of the investment opportunity, including relative attractiveness of a security to different accounts; (iii) relative size of applicable accounts; (iv) impact on overall performance and allocation of such securities may have on accounts; (v) cash and liquidity considerations, including without limitation, availability of cash for investment; (vi) minimum denomination, minimum increments, de minimus threshold and round lot consideration; (vii) account investment horizons, investment objectives and guidelines; (viii) an account’s risk tolerance and/or risk parameters; (ix) tax sensitivity of accounts; (x) concentration of positions in an account; (xi) appropriateness of a security for the account given the benchmark and benchmark sensitivity of an account; (xii) use of the opportunity as a replacement for another security Alger Management believes to be attractive for an account or the availability of other appropriate investment opportunities; (xiii) considerations related to giving a subset of accounts exposure to an industry; and/or (xiv) account turnover guidelines.
In some circumstances, it is possible that the application of these factors may result in certain client/Alger Affiliates accounts receiving an allocation when other accounts do not. Moreover, Alger Affiliates, or accounts in which Alger Affiliates and/or employees have interests, may receive an allocation or an opportunity not allocated to other accounts or the Funds.
Portfolio managers who manage multiple strategies exercise investment discretion over each strategy on an individualized basis and therefore may allocate investments (including IPOs and secondary offerings) in a different manner for each strategy. Considerations for such different allocations, include, but are not limited to, when an allocation to a particular strategy results in a de minimis investment, different investment policies and objectives of one strategy versus another; as well as the implementation of strategy objectives such as sector or industry weightings. As a result of such allocations, there will be instances when funds within a strategy managed by the same portfolio manager do not participate in an investment that is allocated among funds invested in another strategy managed by the same portfolio manager. For example, it is generally the case that investment strategies with larger AUM do not participate in allocations of IPOs and secondary offerings as the allocation of limited shares will result in the strategy receiving de minimis amounts of shares to allocate across strategies. Such investment
54

decisions may result in a loss of investment opportunity for funds that may otherwise have been suited to invest in such offerings.
Please visit www.alger.com for a current list of portfolio managers by strategy as well as strategy AUM.
Differing Guidelines, Objectives and Time Horizons. Because client/Alger Affiliates accounts (including the Funds) are managed according to different strategies and individual client guidelines, certain accounts may not be able to participate in a transaction or strategy employed by Alger Management.
Actions taken by one account could affect others. For example, in the event that withdrawals of capital result in one account selling securities, this could result in securities of the same issuer falling in value, which could have a material adverse effect on the performance of other accounts (including the Funds) that do not sell such positions.
Alger Affiliates may also develop and implement new strategies, which may not be employed in all accounts or pro rata among the accounts where they are employed, even if the strategy is consistent with the objectives of all accounts. Alger Affiliates may make decisions based on such factors as strategic fit and other portfolio management considerations, including an account’s capacity for such strategy, the liquidity of the strategy and its underlying instruments, the account’s liquidity, the business risk of the strategy relative to the account’s overall portfolio make-up, the lack of efficacy of, or return expectations from, the strategy for the account, and any such other factors as Alger Affiliates deem relevant in their sole discretion. For example, such a determination may, but will not necessarily, include consideration of the fact that a particular strategy will not have a meaningful impact on an account given the overall size of the account, the limited availability of opportunities in the strategy and the availability of other strategies for the account.
Investing in Different Classes of the Same Issuer. Conflicts also arise when one or more client/Alger Affiliates accounts (including a Fund) invests in different classes of securities of the same issuer. As a result, one or more client/Alger Affiliates accounts may pursue or enforce rights with respect to a particular issuer in which a Fund has invested, and those activities may have an adverse effect on the Fund. For example, if a client/Alger Affiliates account holds debt securities of an issuer and a Fund holds equity securities of the same issuer, if the issuer experiences financial or operational challenges, the client/Alger Affiliates account which holds the debt securities may seek a liquidation of the issuer, whereas the Fund which holds the equity securities may prefer a reorganization of the issuer. In addition, Alger Management may also, in certain circumstances, pursue or enforce rights with respect to a particular issuer jointly on behalf of one or more client/Alger Affiliates accounts, the Fund, or Alger Affiliates. The Funds may be negatively impacted by Alger Affiliates’ and other client/Alger Affiliates accounts’ activities, and transactions for the Funds may be impaired or effected at prices or terms that may be less favorable than would otherwise have been the case had Alger Affiliates and other client/Alger Affiliates accounts not pursued a particular course of action with respect to the issuer of the securities.
Conflicts Related to Timing of Transactions. When Alger or a client/Alger Affiliates account implements a portfolio decision or strategy ahead of, or contemporaneously with, similar portfolio decisions or strategies for a Fund (whether or not the portfolio decisions emanate from the same research analysis or other information), market impact, liquidity constraints, or other factors could result in the Fund receiving less favorable trading results. In addition, the costs of implementing such portfolio decisions or strategies could be increased or the Fund could otherwise be disadvantaged. Alger Affiliates may, in certain cases, implement internal policies and procedures designed to limit such consequences to client/Alger Affiliates accounts, which may cause a Fund to be unable to engage in certain activities, including purchasing or disposing of securities, when it might otherwise be desirable for it to do so.
Moreover, each client/Alger Affiliates account is managed independently of other accounts. Given the independence in the implementation of advice to these accounts, there can be no warranty that such investment advice will be implemented simultaneously. Neither Alger Management nor its affiliates will always know when advice issued has been executed and, if so, to what extent. Alger Management and its affiliates will use reasonable efforts to procure timely execution. It is possible that prior execution for or on behalf of an account could adversely affect the prices and availability of the securities and instruments in which the Funds invest. In other words, an account, by trading first, may increase the price or decrease the availability of a security to the Funds.
55

In some instances, Alger Management is retained through programs sponsored by unaffiliated financial intermediaries, advisers or planners in which Alger Management serves as an investment adviser (“wrap programs”). Alger Management offers advisory services through single contract programs, dual contract programs and model portfolio programs. Given the structure of the wrap programs and the fact that payments to Alger Management are paid directly by the wrap sponsor, Alger Management does not believe it receives any direct compensation from clients who participate in the wrap programs. Because wrap clients generally pay the wrap sponsor to effect transactions for their accounts, Alger Management does not aggregate transactions on behalf of wrap program accounts with other accounts or funds it advises. Because of the distinct trading process Alger Management follows for wrap accounts and the portfolio limitations of the wrap programs, the timing of trades for wrap accounts may differ from other accounts and will generally be made later in time than for other accounts managed by Alger Management.
The fact that personnel of certain Alger Affiliates are dedicated to one or more Funds, accounts or clients may be a factor in determining the timing of implementation and allocation of opportunities sourced by such personnel. Alger Affiliates may delay trades for a Fund or account in order to aggregate such trades. Alger Affiliates may also consider reputational matters and other considerations. Differences in allocations will affect the performance of the Funds.
Cross Transactions. From time to time and for a variety of reasons, certain client/Alger Affiliates accounts may buy or sell positions in a particular security while a Fund is undertaking the opposite strategy. Trading in the opposite manner could disadvantage the Fund. Moreover, Alger Affiliates may have a potentially conflicting division of loyalties and responsibilities to both parties in such a case. For example, Alger Management will represent both the Fund on one side of a transaction and another account on the other side of the trade (including an account in which Alger Affiliates may have a proprietary interest) in connection with the purchase of a security by such Fund. In an effort to reduce this negative impact, and when permitted by applicable law, the accounts may enter into “cross transactions.” A cross transaction, or cross trade, occurs when the Manager causes a Fund to buy securities from, or sell a security to, another client of Alger Management or Alger Affiliates. Alger Management will ensure that any such cross transactions are effected on commercially reasonable market terms and in accordance with applicable law, including but not limited to Alger Management’s fiduciary duties to all accounts.
Valuation of Assets. Alger Affiliates may have a conflict of interest in valuing the securities and other assets in which a Fund may invest. Alger Management is generally paid an advisory fee based on the value of the assets under management, so more valuable securities will result in a higher advisory fee. Alger Management may also benefit from showing better performance or higher account values on periodic statements.
Certain securities and other assets in which the Funds may invest may not have a readily ascertainable market value and will be valued by Alger Management in accordance with the valuation guidelines described in the valuation procedures adopted by the Funds. Such securities and other assets may constitute a substantial portion of a Fund’s investments. Alger Management’s risk of misstating the value of securities is greater with respect to illiquid securities like those just described.
Alger Affiliates may hold proprietary positions in a Fund. One consequence of such proprietary positions is that Alger Management may be incented to misstate the value of illiquid securities.
Regulatory Conflicts. From time to time, the activities of the Funds may be restricted because of regulatory or other requirements applicable to Alger Affiliates and/or their internal policies designed to comply with, limit the applicability of, or otherwise relate to such requirements. As a result, Alger Affiliates may implement internal restrictions that delay or prevent trades for the Funds, which could result in less favorable execution of trades and may impact the performance of the Funds.
Certain activities and actions may be considered to result in reputational risk or disadvantage for the management of the Funds and Alger Management as well as for other Alger Affiliates. Such situations could arise if Alger Affiliates serve as directors of companies the securities of which a Fund wishes to purchase or sell or is representing or providing financing to another potential purchaser. The larger Alger Management’s investment advisory business and Alger Affiliates’ businesses, the larger the potential that these restricted list policies will impact the performance of the Funds.
Other Potential Conflicts Relating to the Management of the Fund by the Manager
Potential Conflicts Relating to Alger Affiliates’ Proprietary Activities and Activities On Behalf of Other Accounts. Alger Management may purchase or sell, for itself or Alger Affiliates, mutual funds,
56

ETFs or other pooled investment vehicles, commercial paper or fixed-income securities that it recommends to its clients. The results achieved by Alger Affiliates proprietary accounts may differ from those achieved for other accounts. Alger Management will manage the Funds and its other client/Alger Affiliates accounts in accordance with their respective investment objectives and guidelines. However, Alger Management may give advice, and take action, with respect to any current or future client/Alger Affiliates accounts that may compete or conflict with the advice Alger Management may give to the Funds including with respect to the return of the investment, the timing or nature of action relating to the investment or method of exiting the investment.
The directors, officers and employees of Alger Affiliates, including Alger Management, may buy and sell securities or other investments for their own accounts (including through investment funds managed by Alger Affiliates, including Alger Management). As a result of differing trading and investment strategies or constraints, positions may be taken by directors, officers and employees that are the same, different from or made at different times than positions taken for the Funds. To reduce the possibility that the Funds will be materially adversely affected by the personal trading described above, Alger Management has established policies and procedures that restrict securities trading in the personal accounts of investment professionals and others who normally come into possession of information regarding the Funds’ portfolio transactions. Alger Management has adopted a code of ethics (the “Code of Ethics”) and monitoring procedures relating to certain personal securities transactions by personnel of Alger Management which Alger Management deems to involve potential conflicts involving such personnel, client/Alger Affiliates accounts managed by Alger Management and the Funds. The Code of Ethics requires that personnel of Alger Management comply with all applicable federal securities laws and with the fiduciary duties and anti-fraud rules to which Alger Management is subject. The Code of Ethics is available on the EDGAR Database on the SEC’s Internet site at http://www.sec.gov.
Potential Conflicts in Connection With Proxy Voting
Alger Management has adopted policies and procedures designed to prevent conflicts of interest from influencing proxy voting decisions that it makes on behalf of clients, including the Funds, and to help ensure that such decisions are made in accordance with Alger Management’s fiduciary obligations to its clients. Notwithstanding such proxy voting policies and procedures, actual proxy voting decisions of Alger Management may have the effect of favoring the interests of other clients or Alger Affiliates provided that Alger Management believes such voting decisions to be in accordance with its fiduciary obligations. In other words, regardless of what Alger Management’s conflict of interest is, the importance placed on exercising a client’s right to vote dictates that Alger Management will cast the vote in accordance with its voting guidelines even if Alger Management, its affiliate, or its client, somehow, indirectly, benefits from that vote. For a more detailed discussion of these policies and procedures, see the section of this SAI entitled “Proxy Voting Policies and Procedures.”
Conflicts in Connection with Sales-Related Incentives.
Alger Affiliates and its sales personnel may directly or indirectly receive a portion of the fees and commissions charged to a Fund or its shareholders. Alger Affiliates and its advisory or other personnel may also benefit from increased amounts of assets under management. Fees and commissions may also be higher for some products or services than for others, and the remuneration and profitability to Alger Affiliates and such personnel resulting from transactions on behalf of or management of the Funds may be greater or lesser than the remuneration and profitability resulting from other funds or products.
Conflicts may arise in relation to sales-related incentives. Alger Affiliates and its personnel may receive greater compensation or greater profit in connection with certain funds in the Alger Family of Funds than with other funds, including the Funds. Differentials in compensation may be related to the fact that Alger Affiliates may pay a portion of their advisory fee to an unaffiliated investment adviser, or to other compensation arrangements, including for portfolio management, brokerage transactions or account servicing. Any differential in compensation may create a financial incentive on the part of Alger Affiliates and their personnel to recommend certain funds in the Alger Family of Funds over other funds, including the Funds.
Alger Affiliates may also have relationships with, and purchase, or distribute or sell, services or products from or to, distributors, consultants and others who recommend the Funds, or who engage in transactions with or for the Funds. For example, Alger Affiliates regularly participate in industry and consultant sponsored conferences and may purchase educational, data related or other services from consultants or other third parties that it deems to be of value to its personnel and its business. The products and services purchased from consultants may include, but are not limited to, those that help
57

Alger Affiliates understand the consultant’s points of view on the investment management process. Consultants and other parties that provide consulting or other services or provide service platforms for employee benefit plans to potential investors in the Funds may receive fees from Alger Affiliates or the Funds in connection with the distribution of shares in the Funds or other Alger Affiliates products. For example, Alger Affiliates may enter into revenue or fee sharing arrangements with consultants, service providers, and other intermediaries relating to investments in mutual funds, ETFs or other products or services offered or managed by Alger Management. Alger Affiliates may also pay a fee for membership in industry-wide or state and municipal organizations or otherwise help sponsor conferences and educational forums for investment industry participants including, but not limited to, trustees, fiduciaries, consultants, administrators, state and municipal personnel and other clients. Alger Affiliates’ membership in such organizations allows Alger Affiliates to participate in these conferences and educational forums and helps Alger Affiliates interact with conference participants and to develop an understanding of the points of view and challenges of the conference participants. In addition, Alger Affiliates’ personnel, including employees of Alger Affiliates, may have board, advisory, brokerage or other relationships with issuers, distributors, consultants and others that may have investments in the Funds or that may recommend investments in the Funds or distribute the Funds. In addition, Alger Affiliates, including Alger Management, may make charitable contributions to institutions, including those that have relationships with clients or personnel of clients. Personnel of Alger Affiliates may also make political contributions. As a result of the relationships and arrangements described in this paragraph, consultants, distributors and other parties may have conflicts associated with their promotion of the Funds or other dealings with the Funds that create incentives for them to promote the Funds or certain portfolio transactions.
To the extent permitted by applicable law, Alger Affiliates or the Funds may make payments to authorized dealers and other financial intermediaries (“Intermediaries”) from time to time to promote client/Alger Affiliates accounts, the Funds and other products. In addition to placement fees, sales loads or similar distribution charges, payments may be made out of Alger Affiliates’ assets, or amounts payable to Alger Affiliates rather than a separately identified charge to the Funds, client/Alger Affiliates accounts or other products. Such payments may compensate Intermediaries for, among other things: marketing the Funds, client/Alger Affiliates accounts and other products (which may consist of payments resulting in or relating to the inclusion of the Funds, client/Alger Affiliates accounts and other products on preferred or recommended fund lists or in certain sales programs from time to time sponsored by the Intermediaries); access to the Intermediaries’ registered representatives or salespersons, including at conferences and other meetings; assistance in training and education of personnel; fees for directing investors to the Funds, client/Alger Affiliates accounts and other products; “finders fees” or “referral fees” or other fees for providing assistance in promoting the Funds, client/Alger Affiliates accounts and other products (which may include promotions in communications with the Intermediaries’ customers, registered representatives and salespersons); and/or other specified services intended to assist in the distribution and marketing of the Funds, client/Alger Affiliates accounts and other products. Such payments may be a fixed dollar amount; may be based on the number of customer accounts maintained by an Intermediary; may be based on a percentage of the value of interests sold to, or held by, customers of the Intermediary involved; or may be calculated on another basis. The payments may also, to the extent permitted by applicable regulations, contribute to various non-cash and cash incentive arrangements to promote certain products, as well as sponsor various educational programs, sales contests and/or promotions. Furthermore, subject to applicable law, such payments may also pay for the travel expenses, meals, lodging and entertainment of Intermediaries and their salespersons and guests in connection with educational, sales and promotional programs. The additional payments by Alger Affiliates may also compensate Intermediaries for subaccounting, administrative and/or shareholder processing or other investor services that are in addition to the fees paid for these services by such products.
The payments made by Alger Affiliates or the Funds may be different for different Intermediaries. The payments may be negotiated based on a range of factors, including but not limited to, ability to attract and retain assets, target markets, customer relationships, quality of service and industry reputation. Payment arrangements may include breakpoints in compensation which provide that the percentage rate of compensation varies as the dollar value of the amount sold or invested through an Intermediary increases. The presence of these payments and the basis on which an Intermediary compensates its registered representatives or salespersons may create an incentive for a particular Intermediary, registered representative or salesperson to highlight, feature or recommend certain products based, at least in part, on the level of compensation paid.
Potential Conflicts in Connection with Brokerage Transactions
58

Trade Aggregation. If Alger Management believes that the purchase or sale of a security is in the best interest of more than one client/Alger Affiliates account (including the Funds), it may (but is not obligated to) aggregate the orders to be sold or purchased to seek favorable execution or lower brokerage commissions, to the extent permitted by applicable laws and regulations. Aggregation of trades under this circumstance may, on average, decrease the costs of execution. In the event Alger Management aggregates a trade for participating accounts, the method of allocation will generally be determined prior to the trade execution. Although no specific method of allocation of trades is expected to be used, allocations are generally pro rata and if not, will be designed so as not to systematically and consciously favor or disfavor any account in the allocation of investment opportunities. The accounts aggregated may include registered and unregistered investment companies, Alger Affiliates Accounts (including the Funds), and separate accounts. Transaction costs will be shared by participants on a pro-rata basis according to their allocations. Alger Management may delay the execution of a trade for a client account so it may be included as part of an aggregated trade.
When orders are aggregated for execution, it is possible that Alger Affiliates will benefit from such trades, even in limited capacity situations. Alger Management maintains policies and procedures that it believes are reasonably designed to deal equitably with conflicts of interest that may arise when purchase or sale orders for an account are aggregated for execution with orders for Alger Affiliates Accounts. Alger Management may aggregate trades for its clients and affiliates in private placements pursuant to internally developed procedures. In such cases, Alger Management will only negotiate the price of such investments, and no other material terms of the offering, and will prepare a written allocation statement reflecting the allocation of the securities.
Orders to purchase or sell the same security need not be aggregated if there is a reasonable distinction between or among the orders. For example, orders that are not price specific need not be aggregated with orders that are to be executed at a specific price. Also, certain short sale trades may not be aggregated due to settlement issues and may not trade sequentially in order to maintain the average trade price.
Alger Management is not required to bunch or aggregate trades if portfolio management decisions for different accounts are made separately, or if it determines that bunching or aggregating is not practicable, or with respect to client directed accounts.
Even when trades are aggregated, prevailing trading activity frequently may make impossible the receipt of the same price or execution on the entire volume of securities purchased or sold. When this occurs, the various prices may be averaged, and the Funds will be charged or credited with the average price. Thus, the effect of the aggregation may operate on some occasions to the disadvantage of the Funds. In addition, under certain circumstances, the Funds will not be charged the same commission or commission equivalent rates in connection with a bunched or aggregated order.
Soft Dollars. Alger Management relies primarily on its own internal research to provide primary research in connection with buy and sell recommendations. However, Alger Management does acquire research services provided by a third party vendor, which it pays for with brokerage fees and commissions, sometimes referred to as “soft dollars.” The services that Alger Management may receive include: management meetings; conferences; research on specific industries; research on specific companies; macroeconomic analyses; analyses of national and international events and trends; evaluations of thinly traded securities; computerized trading screening techniques and securities ranking services; general research services (i.e. Bloomberg, FactSet).
Alger Management may pay higher commissions for receipt of brokerage and research services in connection with securities trades that are consistent with the “safe harbor” provisions of Section 28(e) of the Securities Exchange Act of 1934, as amended (the “Securities Exchange Act”). This benefits Alger Management because it does not have to pay for the research, products, or services. Such benefit gives Alger Management an incentive to select a broker-dealer based on its interest in receiving the research, products, or services rather than on its clients’ interest in receiving the most favorable execution.
Research or other services obtained in this manner may be used in servicing any or all of the Funds and other client/Alger Affiliates accounts. This includes accounts other than those that pay commissions to the broker providing soft dollar benefits. Therefore, such products and services may disproportionately benefit certain client/Alger Affiliates accounts, including the Funds, to the extent that the commissions from such accounts are not used to purchase such services.
Neither the research services nor the amount of brokerage given to a particular broker-dealer are
59

made through an arrangement or commitment that obligates Alger Management to pay selected broker-dealers for the services provided.
Alger Management has entered into certain commission sharing arrangements. A commission sharing arrangement allows Alger Management to aggregate commissions at a particular broker-dealer, and to direct that particular broker-dealer to pay various other broker-dealers from this pool of aggregate commissions for research and research services the broker-dealers have provided to Alger Management. These arrangements allow Alger Management to limit the broker-dealers it trades with, while maintaining valuable research relationships.
Additionally, Alger Management receives a credit for routing orders through a fixed connection with a national securities exchange, which is applied to the costs of research services.
In certain cases, a research service may serve additional functions that are not related to the making of investment decisions (such as accounting, record keeping or other administrative matters). Where a product obtained with commissions has such a mixed use, Alger Management will make a good faith allocation of the cost of the product according to its use. Alger Management will not use soft dollars to pay for services that provide only administrative or other non-research assistance.

Appendix
Description of certain rating categories assigned by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), Moody’s Investors Service, Inc. (“Moody’s”), Fitch, Inc. (“Fitch”), Dominion Bond Rating Service Limited (“DBRS”) and A. M. Best Company, Inc. (“Best”).
Commercial Paper and Short-Term Ratings
The designation A-l by S&P indicates that the degree of safety regarding timely payment is either overwhelming or very strong. Those issues determined to possess overwhelming safety characteristics are denoted with a plus sign (+) designation. Capacity for timely payment on issues with an A-2 designation is strong. However, the relative degree of safety is not as high as for issues designated A-l.
The rating Prime-l (P-l) is the highest commercial paper rating assigned by Moody’s. Issuers of P-l paper must have a superior capacity for repayment of short-term promissory obligations and ordinarily will be evidenced by leading market positions in well-established industries, high rates of return of funds employed, conservative capitalization structures with moderate reliance on debt and ample asset protection, broad margins in earnings coverage of fixed financial charges and high internal cash generation, and well-established access to a range of financial markets and assured sources of alternate liquidity. Issues rated Prime-2 (P-2) have a strong capacity for repayment of short-term promissory obligations. This ordinarily will be evidenced by many of the characteristics cited above, but to a lesser degree. Earnings trends and coverage ratios, while sound, will be more subject to variation. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.
The rating Fitch-l (Highest Grade) is the highest commercial paper rating assigned by Fitch. Paper rated Fitch-l is regarded as having the strongest degree of assurance for timely payment. The rating Fitch-2 (Very Good Grade) is the second highest commercial paper rating assigned by Fitch which reflects an assurance of timely payment only slightly less in degree than the strongest issues.
Bond and Long-Term Ratings S&P
Bonds rated AA by S&P are judged by S&P to be high-grade obligations and in the majority of instances differ only in small degree from issues rated AAA (S&P’s highest rating). Bonds rated AAA are considered by S&P to be the highest grade obligations and possess the ultimate degree of protection as to principal and interest. With AA bonds, as with AAA bonds, prices move with the long-term money market. Bonds rated A by S&P have a strong capacity to pay principal and interest, although they are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions.
S&P’s BBB-rated bonds, or medium-grade category bonds, are borderline between definitely sound obligations and those where the speculative elements begin to predominate. These bonds have adequate asset coverage and normally are protected by satisfactory earnings. Their susceptibility to changing conditions, particularly to depressions, necessitates constant watching. These bonds generally are more responsive to business and trade conditions than to interest rates. This group is the lowest that qualifies for commercial bank investment.
Debt rated BB and B by S&P is regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal. While such debt will likely have some quality and protective characteristics, these are outweighed by large uncertainties or major risk exposures to adverse conditions.
Debt rated BB has less near-term vulnerability to default than other speculative grade debt. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions that could lead to inadequate capacity to meet timely interest and principal payments. The BB rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BBB rating.
Debt rated B by S&P has greater vulnerability to default but presently has the capacity to meet interest payments and principal repayments. Adverse business, financial, or economic conditions would likely impair capacity or willingness to pay interest and repay principal. The B rating category also is used for debt subordinated to senior debt that is assigned an actual or implied BB or B rating.
61

MOODY’S
Bonds rated Aa by Moody’s are judged to be of high quality by all standards. Together with bonds rated Aaa (Moody’s highest rating) they comprise what are generally known as high-grade bonds. Aa bonds are rated lower than Aaa bonds because margins of protection may not be as large as those of Aaa bonds, or fluctuation of protective elements may be of greater amplitude, or there may be other elements present that make the long-term risks appear somewhat larger than those applicable to Aaa securities. Bonds that are rated A by Moody’s possess many favorable investment attributes and are to be considered as upper medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present that suggest a susceptibility to impairment in the future.
Moody’s Baa-rated bonds are considered as medium-grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present, but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and, in fact, have speculative characteristics as well.
Bonds rated Ba by Moody’s are judged to have speculative elements; their future cannot be considered as well-assured. Often the protection of interest and principal payments may be very moderate and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.
Bonds rated B by Moody’s generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.
Moody’s applies the numerical modifiers 1, 2 and 3 to each generic rating classification from Aa through B. The modifier 1 indicates that the security ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates that the issue ranks in the lower end of its generic rating category.
FITCH
Bonds rated AAA by Fitch are judged by Fitch to be strictly high-grade, broadly marketable, suitable for investment by trustees and fiduciary institutions and liable to but slight market fluctuation other than through changes in the money rate. The prime feature of an AAA bond is a showing of earnings several times or many times interest requirements, with such stability of applicable earnings that safety is beyond reasonable question whatever changes occur in conditions. Bonds rated AA by Fitch are judged by Fitch to be of safety virtually beyond question and are readily salable, whose merits are not unlike those of the AAA class, but whose margin of safety is less strikingly broad. The issue may be the obligation of a small company, strongly secured but influenced as to rating by the lesser financial power of the enterprise and more local type of market.
Bonds rated A by Fitch are considered to be investment grade and of high credit quality. The obligor’s ability to pay interest and repay principal is considered to be strong, but may be more vulnerable to adverse changes in economic conditions and circumstances than bonds with higher ratings.
BBB-rated bonds are considered to be investment grade and of satisfactory credit quality. The obligor’s ability to pay interest and repay principal is considered to be adequate. Adverse changes in economic conditions and circumstances, however, are more likely to have adverse impact on these bonds, and therefore impair timely payment. The likelihood that the ratings of these bonds will fall below investment grade is higher than for bonds with higher ratings.
Fitch’s BB-rated bonds are considered speculative. The obligor’s ability to pay interest and repay principal may be affected over time by adverse economic changes. However, business and financial alternatives can be identified which could assist the obligor in satisfying its debt service requirements.
Fitch’s B-rated bonds are considered highly speculative. While bonds in this class are currently meeting debt service requirements, the probability of continued timely payment of principal and interest reflects the obligor’s limited margin of safety and the need for reasonable business and economic activity throughout the life of the issue.

DBRS
Bonds rated AAA by DBRS are considered to be of the highest credit quality, with exceptionally strong protection for the timely repayment of principal and interest. Earnings are considered stable, the structure of the industry in which the entity operates is strong, and the outlook for future profitability is favorable. There are few qualifying factors present which would detract from the performance of the entity, the strength of liquidity and coverage ratios is unquestioned and the entity has established a creditable track record of superior performance. Given the extremely tough definition which DBRS has established for this category, few entities are able to achieve a AAA rating.
Bonds rated AA are of superior credit quality, and protection of interest and principal is considered high. In many cases, they differ from bonds rated AAA only to a small degree. Given the extremely tough definition which DBRS has for the AAA category (which few companies are able to achieve), entities rated AA are also considered to be strong credits which typically exemplify above-average strength in key areas of consideration and are unlikely to be significantly affected by reasonably foreseeable events.
Bonds rated A are of satisfactory credit quality. Protection of interest and principal is still substantial, but the degree of strength is less than with AA rated entities. While a respectable rating, entities in the A category are considered to be more susceptible to adverse economic conditions and have greater cyclical tendencies than higher rated companies.
Bonds rated BBB are considered to be of adequate credit quality. Protection of interest and principal is considered adequate, but the entity is more susceptible to adverse changes in financial and economic conditions, or there may be other adversities present which reduce the strength of the entity and its rated securities.
Bonds rated BB are defined to be speculative, where the degree of protection afforded interest and principal is uncertain, particularly during periods of economic recession. Entities in the BB area typically have limited access to capital markets and additional liquidity support and, in many cases, small size or lack of competitive strength may be additional negative considerations.
Bonds rated “B” are regarded as highly speculative and there is a reasonably high level of uncertainty as to the ability of the entity to pay interest and principal on a continuing basis in the future, especially in periods of economic recession or industry adversity.
A.M. Best
The issuer of long-term debt rated aaa has, in A.M. Best’s opinion, an exceptional ability to meet the terms of its obligation. The rating aa is assigned to issues where the issuer has, in A.M. Best’s opinion, a very strong ability to meet the terms of its obligation., and issues are rated a where the ability to meet the terms of the obligation is regarded as strong. The issuer of debt rated bbb is considered to have an adequate ability to meet the terms of its obligation but to be more susceptible to changes in economic or other conditions.
The issuer of bb-rated long-term debt has, in A.M. Best’s opinion, speculative credit characteristics, generally due to a moderate margin of principal and interest payment protection and vulnerability to economic changes. The issuer of long-term debt rated b is considered to have extremely speculative credit characteristics, generally due to a modest margin of principal and interest payment protection and extreme vulnerability to economic changes.

Item 30.
INDEMNIFICATION
Under Section 8.4 of Registrant’s Agreement and Declaration of Trust, any past or present Trustee or officer of Registrant (including persons who serve at Registrant’s request as directors, officers or Trustees of another organization in which Registrant has any interest as a shareholder, creditor or otherwise (hereinafter referred to as a “Covered Person”)) is indemnified to the fullest extent permitted by law against liability and all expenses reasonably incurred by him in connection with any action, suit or proceeding to which he may be a party or otherwise involved by reason of his being or having been a Covered Person. This provision does not authorize indemnification when it is determined, in the manner specified in the Agreement and Declaration of Trust, that such Covered Person has not acted in good faith in the reasonable belief that his actions were in or not opposed to the best interests of Registrant. Moreover, this provision does not authorize indemnification when it is determined, in the manner specified in the Agreement and Declaration of Trust, that such Covered Person would otherwise be liable to Registrant or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his duties. Expenses may be paid by Registrant in advance of the final disposition of any action, suit or proceeding upon receipt of an undertaking by such Covered Person to repay such expenses to Registrant in the event that it is ultimately determined that indemnification of such expenses is not authorized under the Agreement and Declaration of Trust and either (i) the Covered Person provides security for such undertaking, (ii) Registrant is insured against losses from such advances, or (iii) the disinterested Trustees or independent legal counsel determines, in the manner specified in the Agreement and Declaration of Trust, that there is reason to believe the Covered Person will be found to be entitled to indemnification.
Insofar as indemnification for liability arising under the Securities Act of 1933 (the “Securities Act”) may be permitted to Trustees, officers and controlling persons of Registrant pursuant to the foregoing provisions, or otherwise, Registrant has been advised that in the opinion of the Securities and Exchange Commission (the “SEC”) such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by Registrant of expenses incurred or paid by a Trustee, officer or controlling person of Registrant in the successful defense of any action, suit or proceeding) is asserted by such Trustee, officer or controlling person in connection with the securities being registered, Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
