Shareholders’ Letter (Unaudited)

April 30, 2020

Dear Shareholders,

Reasons for Optimism Surface as Pandemic Drives Market Volatility

At Alger, we see plenty of reasons for optimism regarding equity investing and the well-being of society as governments seek to curtail the spread of the coronavirus, but we acknowledge that the pandemic will continue to create both personal and economic hardships in the foreseeable future. During the recent months of uncertainty and fear, we have strived to support our shareholders by drawing upon our 55 years of investing experience to seek companies that are best positioned to potentially generate durable earnings growth, and we have shared our insights on managing equities during challenging times to help our clients manage their apprehensions.

In this letter, which discusses the six-month reporting period ended April 30, 2020, I provide additional perspectives on navigating markets during the pandemic and I explain why I believe equities, while continuing to be volatile, may produce additional gains.

A Challenging Time

From the start of the reporting period until February 19 of this year, the S&P 500 Index climbed 12.18%. The spread of the novel coronavirus worldwide, however, caused investor sentiment to plummet and from the February 19 historical market peak to March 23 the index dropped 33.79%. As countries issued stay-at-home orders and shut down businesses to contain the pandemic, economic data weakened considerably. In the U.S., the Congressional Budget Office eventually predicted that gross domestic product (GDP) will contract at nearly a 40% annual rate in the second quarter of this year and unemployment will climb from a 50-year low to a peak of 16% later this year. With 24% of S&P 500 companies reporting during the last week of the reporting period, FactSet Research estimated that first quarter 2020 earnings would decline 15.8%, the largest drop since the second quarter of 2009.

In March, the Federal Reserve (“the Fed”) responded aggressively to the pandemic by implementing two rate cuts that totaled 150 basis points, bringing the fed funds target rate to ..0% - .25%. The Fed also unveiled a round of quantitative easing that could dwarf prior easing programs while U.S. legislators began creating programs initially valued at more than $2 trillion to support businesses, increase unemployment benefits and provide one-time payments to certain individuals. Hope that the stimulus plans could help mitigate the economic impact of the pandemic caused equities to bounce back and from March 24 until April 30, the S&P 500 Index recorded a 30.8% gain.

As the reporting period drew to a close, various U.S. states and certain countries began to re-open their economies as the rates of new coronavirus cases either stabilized or declined. For the six-month reporting period, the S&P 500 recorded a 3.16% loss. Volatility extended beyond the U.S. with the MSCI Emerging Markets Index declining 10.39% and the MSCI ACWI ex USA Index declining 13.02%. Broadly speaking, companies with strong balance sheets and innovative products that are experiencing growing demand as a result of the pandemic outperformed while “old economy” industries such as energy, manufacturing, brick and mortar retailers and certain travel companies including airlines, cruise ship operators and hotels performed worst.

Keeping Change in Perspective

At Alger, we believe history illustrates that companies with innovative products and services can dominate their industries by disrupting their respective industries and capturing market share. These types of companies can potentially reward investors by growing their earnings despite economic headwinds.

Consider the following examples:

The “Spanish Flu” pandemic and recession, which lasted from 1918 to 1919 and claimed 50 million lives. During this period, automobile ownership grew at a double-digit rate.

The Great Depression, which lasted from 1929 through 1939. In 1937 DuPont introduced neoprene, which is a synthetic rubber. By 1939, every automobile and airplane manufactured in the U.S. included products made with the material. Hewlett-Packard and Polaroid were also born during the Great Depression.

The “Asian Flu” pandemic and recession, which occurred in the late 1950s. During this event television ownership increased 12% after the introduction of color TV.

The recession of the early 1990s. During this event, personal computer penetration grew.

The Global Financial Crisis and Great Recession of 2008. During this event, smartphone subscribers, digital advertising and online retail sales all increased.

Pandemic Hastens Change

Today, internet connected devices, cloud computing, artificial intelligence, the Internet of Things, genetic sciences, medtech and healthcare advances, and other technologies are fostering innovation that is occurring at unprecedented levels. In many instances, the coronavirus pandemic is accelerating the already rapid pace at which new products and services disrupt their industries and capture market share. During the early months of the pandemic, credit card data showed that overall consumer spending declined substantially as shopping malls closed, but consumers’ online shopping has seen near exponential acceleration while people have been under stay-at-home orders.¹ The increased adoption of ecommerce by consumers is comparable to the total growth in adoption that we believe would have occurred over the coming two years without the pandemic. This acceleration is occurring after decades of growth in online retailing, which increased 14.9% last year while overall retail sales increased only 3.8%. This strong growth trend of course benefits large online retailers such as Amazon.com, Inc. but it is also helping smaller retailers who have had the foresight to adopt and even primarily build their businesses online, rather than in physical stores, often using ecommerce software platforms from companies such as Shopify, Square and Hubspot.

The structure and rhythm of the American workplace (and indeed across the globe) may be forever changed as a result of the response to Covid-19. With offices shut down, many businesses have had to immediately expand remote working to the majority, if not all, of their employees. Many lessons will be learned from this mass shift to telecommuting. However, we believe that even after this healthcare crisis passes and offices re-open, there will be a shift in the perception and therefore the use of telecommuting. In particular, for many businesses and for many job roles, we believe both workers and employers are seeing efficiency gains while “working from home” and will adopt more flexible policies in the future to not only allow working from home but perhaps encourage it more broadly and frequently within their future workforce. The use of many of the new technologies that support online collaboration, videoconferencing, and business process management, even as workers are remote, is being tested now on an emergency and broad basis, and the technologies are proving themselves to be largely exceptional in their potential for changing how we work in the future. To support this massive shift, technology needs to not only provide collaborative workstations for employees, but also increased network capacity and security. Nearly every provider of internet bandwidth or data center computing power is reporting significant increases in demand. Additionally, security firms such as CrowdStrike that provide end-point protection against viruses, malware and other digital threats are experiencing increased demand for cloud-based security systems. In both government and commercial firms, the need for real-time communication with the public or their employees has driven the adoption of new communications platforms to manage the dialogue. Software company Everbridge, for example, announced during the first quarter of this year that it had processed more than 13 million messages related to the pandemic.

We have long been investors in the healthcare sector, which we view as one of the most dynamic and innovative sectors in the U.S., and indeed, the world. Today, we are seeing the valor of doctors and nurses in New York in particular, Alger’s home for over 55 years, and across the U.S. and the globe. We believe this crisis will bring benefits to healthcare systems worldwide as lessons learned from this pandemic will result in new investment in public health, strengthening our hospitals’ and service providers’ capacity to respond rapidly and flexibly to future crises, and by accelerating investment in innovations from the research lab, to testing and clinical treatments and processes, and finally to the delivery of healthcare services by our doctors and nurses on the frontline of patient care. Early growth trends like telemedicine have already proven critical in this crisis, and after it ends, we believe will have become the new way of delivering healthcare to people in the U.S. – that is a technology trend whose adoption “curve,” we believe, has the potential to go from birth to mainstream potentially faster than any we have seen before.

Going Forward

We believe market volatility will continue in the coming months due to declining earnings and heightened uncertainty. As the quarterly reporting season progressed in April, companies increasingly withdrew their guidance for fiscal year 2020 due to uncertainty regarding the future impacts of the pandemic. Analysts are projecting a substantial decline in earnings for calendar year 2020 but expect earnings growth to resume next year.

We are optimistic that an eventual recovery in earnings growth, low interest rates and a return to more normal conditions resulting from a potential coronavirus vaccine or new treatments for Covid-19 could support equity markets. Unlike most recessions, the current economic slowdown is being driven by a public health crisis rather than structural issues, such as toxic debt built upon a housing bubble that triggered the Global Financial Crisis. Regardless of the timing, we believe investors should take a long-term approach rather than try to time markets. We also think investors will be best served by using in-depth fundamental research to find companies that are gaining market share and producing durable earnings growth with innovative products and services and, more specifically, are able to benefit from the global economic dislocation occurring from the pandemic. Additionally, we believe innovative companies with strong balance sheets that can finance their own growth initiatives rather than rely on leverage may be best positioned to outperform. At Alger, we continue to seek companies that are benefiting from change as we seek to help our valued clients meet their financial needs.

Portfolio Matters

Alger Capital Appreciation Institutional Fund

The Alger Capital Appreciation Institutional Fund returned 9.39% for the fiscal six-month period ended April 30, 2020, compared to the 6.09% return of the Russell 1000 Growth Index.

Contributors to Performance

During the reporting period, the largest portfolio sector weightings were Information Technology and Consumer Discretionary. The largest sector overweight was Consumer Discretionary and the largest underweight was Consumer Staples. The Consumer Discretionary and Industrials sectors provided the greatest contributions to relative performance.

Among individual positions, Amazon.com, Inc.; Microsoft Corp.; Adobe, Inc.; Apple, Inc.; and NVIDIA Corp. were the top contributors to performance. Amazon.com continues to generate strong high unit volume growth by taking market share from brick and mortar retailing and by growing its cloud computing service. During the reporting period, consumer uptake of one-day shipping supported the acceleration of the company’s online retailing. Later in the reporting period, investors became excited about the significant revenue gains associated with coronavirus quarantining and social distancing that are accelerating the pace at which ecommerce is capturing market share from traditional retailers. Additionally, investors reacted favorably to the pandemic creating increased demand for Amazon.com’s cloud service, AWS.

Detractors from Performance

The Materials and Energy sectors were among the sectors that detracted from results. Regarding individual positions, Raytheon Co.; Aptiv PLC; Boeing Co.; Dollar Tree, Inc.; and Morgan Stanley were among the top detractors from performance. Boeing is a leading producer of passenger jets and is a significant U.S. defense contractor. Boeing’s leading proprietary technology has allowed the company to be a stronger exporter of high-value, high-ticket capital goods. Shares of Boeing underperformed early in the reporting period in response to the company struggling to address software-related safety issues that have grounded 737 MAX planes for longer than originally anticipated. Additionally, regulators scrutinized the safety of the product and Boeing announced that it was suspending production of the MAX beginning in January while a resolution to the problem is sought. Boeing’s board of directors also terminated the company’s chief executive officer. More recently, fears that the global pandemic would spark a large decrease in air travel triggered a selloff of Boeing shares in late February that continued through the early portion of March. We sold our position in the company late in the reporting period.

Alger Focus Equity Fund

The Alger Focus Equity Fund returned 10.90% for the fiscal six-month period ended April 30, 2020, compared to the 6.09% return of the Russell 1000 Growth Index.

Contributors to Performance

During the reporting period, the largest sector weightings were Information Technology and Consumer Discretionary. The largest sector overweight was Information Technology and the largest underweight was Consumer Staples. The Industrials and Consumer Discretionary sectors provided the greatest contributions to relative performance.

Regarding individual positions, Amazon.com, Inc.; Microsoft Corp.; Adobe, Inc.; NVIDIA Corp.; and Alibaba Group Holding Ltd., Sponsored ADR, Cl. A were among the top contributors to performance. Shares of Amazon.com outperformed in response to developments identified in the Alger Capital Appreciation Institutional Fund discussion.

Detractors from Performance

The Communication Services and Materials sectors were among the sectors that detracted from results. Regarding individual positions, Live Nation Entertainment, Inc.; Aptiv PLC; Morgan Stanley; Sherwin-Williams Co.; and Luckin Coffee, Inc. Sponsored ADR, Cl. A were among the top detractors from performance. Live Nation Entertainment is the music industry’s largest concert promotor. Prior to the coronavirus pandemic, it was rapidly increasing the list of artists whose concerts it promotes and the volume of the company’s ticket sales was also growing significantly. In February, fears that the spread of the coronavirus could dramatically curtail live concerts sparked a selloff of Live Nation Entertainment stock that continued through the early portion of March. Investors’ fear materialized when Live Nation Entertainment was forced to cancel thousands of concerts in response to government stay-at-home orders and bans on events that attract large crowds of individuals. Live Nation Entertainment also announced that it would refund tickets for the cancelled events.

Alger Mid Cap Growth Institutional Fund

The Alger Mid Cap Growth Institutional Fund returned 2.68% for the fiscal six-month period ended April 30, 2020, compared to the -1.78% return of the Russell Midcap Growth Index.

Contributors to Performance

During the reporting period, the largest sector weightings were Information Technology and Healthcare. The largest sector overweight was Healthcare and the largest underweight was Information Technology. The Healthcare and Financials sectors provided the largest contributions to relative performance.

Regarding individual positions, DexCom, Inc.; CrowdStrike Holdings, Inc., Cl. A; Advanced Micro Devices, Inc.; Teladoc Health, Inc.; and Shopify, Inc., Cl. A were among the top contributors to performance. Teladoc is a global leader in comprehensive virtual healthcare services. Teladoc provides virtual healthcare on both a business-to-business and direct-to-consumer basis and completed approximately 4.1 million telehealth visits in 2019. Teladoc has a global operational scale unmatched in the telemedicine industry, covering more than 450 subspecialties and servicing patients from more than 175 countries around the globe. Following the Covid-19 outbreak, Teladoc has seen an unprecedented surge in demand for its services as patients turn to telemedicine as a means of receiving necessary medical treatment while limiting unnecessary exposure to in-clinic infections. Healthcare regulators have encouraged the adoption of telemedicine and have relaxed reimbursement restrictions for telemedicine visits, further accelerating this demand growth. We believe that the additional demand generated from Covid-19 is helping to accelerate the long-term secular trend toward greater reliance on telemedicine throughout healthcare. Teladoc’s stock price surged in response to the growing demand for its services resulting from Covid-19.

Detractors from Performance

The Industrials and Consumer Staples sectors were among the sectors that detracted from results. Among individual positions, Bed Bath & Beyond Inc.; Live Nation Entertainment, Inc.; Middleby Corp.; TransDigm Group, Inc.; and Cintas Corp. were top detractors from performance. Shares of Live Nation Entertainment underperformed in response to developments identified in the Alger Focus Equity Fund discussion.

Alger Small Cap Growth Institutional Fund

The Alger Small Cap Growth Institutional Fund returned 12.13% for the fiscal six-month period ended April 30, 2020, compared to the -7.62% return of the Russell 2000 Growth Index.

Contributors to Performance

During the reporting period, the largest sector weightings were Healthcare and Information Technology. The largest sector overweight was Information Technology and the largest underweight was Industrials. The Information Technology and Healthcare sectors provided the largest contributions to relative performance. Regarding individual positions, Quidel Corp.; DexCom, Inc.; Shopify, Inc., Cl. A; Veeva Systems, Inc., Cl. A; and Insulet Corp. were top contributors to performance. Quidel develops, manufactures and markets rapid point-of-care diagnostic testing solutions worldwide that are used for infectious disease, cardiovascular, toxicology, women’s health, gastrointestinal diseases and other healthcare areas. Quidel’s diagnostics are mainly used at point-of-care locations, such as physicians’ offices, hospitals, urgent care clinics, pharmacies, wellness screening clinics and clinical laboratories. Shares of Quidel outperformed during the reporting period in response to the company announcing strong results for the last three months of 2019 and providing strong guidance for this year. Quidel’s results benefitted from a stronger-than-expected 2019-2020 U.S. flu season. Additionally, the performance of Quidel shares benefited from the Covid-19 outbreak because the company’s influenza and other respiratory tests can rule out non-coronavirus causes of a patient’s symptoms. Quidel also has various potential drivers of growth, including a new toxicology panel, a high sensitivity troponin test in Europe for cardiac healthcare and a new Lyme Disease test. Quidel also offers diagnostic test solutions for the ongoing Covid-19 pandemic.

Detractors from Performance

The Communication Services and Energy sectors were among the sectors that detracted from results. Regarding individual positions, Cantel Medical Corp.; Live Nation Entertainment, Inc.; Bed Bath & Beyond Inc.; Blackbaud, Inc.; and Shake Shack, Inc., Cl. A. were among the top detractors from performance. Shares of Live Nation Entertainment underperformed in response to developments identified in the Alger Focus Equity Fund discussion.

I thank you for putting your trust in Alger.

Each Fund offers one or more of the following share classes: Class A, C, I, R, Y, Z and Z-2. Class A shares are generally subject to an initial sales charge while Class C shares are generally subject to a deferred sales charge. Class I, R, Y, Z and Z-2 shares are sold to institutional investors without an initial or deferred sales charge. Class C shares will automatically convert to Class A shares on the fifth business day of the month following the tenth anniversary of the purchase date of a shareholder’s Class C shares, without the imposition of any sales load, fee or other charge. Class C shares held at certain dealers may not convert to Class A shares or may be converted on a different schedule. At conversion, a proportionate amount of shares representing reinvested dividends and distributions will also be converted into Class A shares. Effective August 27, 2019, Class C shares were closed to direct shareholders and are available for purchase through certain financial intermediaries and group retirement plan recordkeeping platforms. Each class has identical rights to assets and earnings, except that each share class bears the pro rata allocation of the Fund’s expenses other than a class expense (not including advisory or custodial fees or other expenses related to the management of the Fund’s assets).

NOTE 2 — Significant Accounting Policies:

(a) Investment Valuation:The Funds value their financial instruments at fair value using independent dealers or pricing services under policies approved by the Trust’s Board of Trustees (the “Board”). Investments held by the Funds 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 Standard Time).

Investments in money market funds and short-term securities held by the Funds 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.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (Continued)

Debt securities generally trade in the over-the-counter market. Debt securities with remaining maturities of more than sixty days at the time of acquisition are valued on the basis of the last available bid prices or current market quotations provided by dealers or pricing services. In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, pricing matrixes, market transactions in comparable investments, various relationships observed in the market between investments and calculated yield measures based on valuation technology commonly employed in the market for such investments. Asset-backed and mortgage-backed securities are valued by independent pricing services using models that consider estimated cash flows of each tranche of the security, establish a benchmark yield and develop an estimated tranche-specific spread to the benchmark yield based on the unique attributes of the tranche. Debt securities with a remaining maturity of sixty days or less are valued at amortized cost which approximates market value.

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 and described further herein.

Securities in which the Funds 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 Trust’s investment adviser, pursuant to policies established by the Board, believes to be the fair value 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.

FASB Accounting Standards Codification 820 – Fair Value Measurements and Disclosures (“ASC 820”) defines fair value as the price that the Funds would receive upon selling an investment in a timely transaction to an independent buyer in the principal or most advantageous market of the investment. ASC 820 established a three-tier hierarchy to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability and may be observable or unobservable. Observable inputs are based on market data obtained from sources independent of the Funds. Unobservable inputs are inputs that reflect the Funds’ own assumptions based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized in the three broad Levels listed below.

Level 1 – quoted prices in active markets for identical investments

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

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

NOTES TO FINANCIAL STATEMENTS (Unaudited) (Continued)

The Funds’ 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. Inputs for Level 1 include exchange-listed prices and broker quotes in an active market. Inputs for Level 2 include the last trade price in the case of a halted security, an exchange-listed price which has been adjusted for fair value factors, and prices of closely related securities. Additional Level 2 inputs include an evaluated price which is based upon a compilation of observable market information such as spreads for fixed income and preferred securities. Inputs for Level 3 include, but are not limited to, revenue multiples, earnings before interest, taxes, depreciation and amortization (“EBITDA”) multiples, discount rates, time to exit and the probabilities of success of certain outcomes. Such unobservable market information may be obtained from a company’s financial statements and from industry studies, market data, and market indicators such as benchmarks and indexes. Because of the inherent uncertainty and often limited markets for restricted securities, the values may significantly differ from the values if there was an active market.

Valuation processes are determined by a Valuation Committee (“Committee”) authorized by the Board and comprised of representatives of the Trust’s investment adviser and officers of the Trust. The Committee reports its fair valuation determinations and related valuation information to the Board. The Board is responsible for approving valuation policy and procedures.

While the Committee meets on an as-needed basis, the Committee generally meets quarterly to review and evaluate the effectiveness of the procedures for making fair value determinations. The 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 Funds’ pricing vendor, and variances between transactional prices and the previous day’s price.

(b) Cash and Cash Equivalents:Cash and cash equivalents include U.S. dollars and overnight time deposits.

(c) Securities Transactions and Investment Income:Securities transactions are recorded on a trade date basis. Realized gains and losses from securities transactions are recorded on the identified cost basis. Dividend income is recognized on the ex-dividend date and interest income is recognized on the accrual basis.

Premiums and discounts on debt securities purchased are amortized or accreted over the lives of the respective securities.

(d) Foreign Currency Transactions:The books and records of the Funds are maintained in U.S. dollars. Foreign currencies, investments and other assets and liabilities are translated into U.S. dollars at the prevailing rates of exchange on the valuation date. Purchases and sales of investment securities and income and expenses are translated into U.S. dollars at the prevailing exchange rates on the respective dates of such transactions.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (Continued)

Net realized gains and losses on foreign currency transactions represent net gains and losses from the disposition of foreign currencies, currency gains and losses realized between the trade dates and settlement dates of security transactions, and the difference between the amount of net investment income accrued and the U.S. dollar amount actually received. The effects of changes in foreign currency exchange rates on investments in securities are included in realized and unrealized gain or loss on investments in the accompanying Statements of Operations.

(e) Dividends to Shareholders:Dividends and distributions payable to shareholders are recorded by the Funds on the ex-dividend date. Dividends from net investment income, if available, and distributions from net realized gains, offset by any loss carryforward, are declared and paid annually after the end of the fiscal year in which earned.

Each class is treated separately in determining the amounts of dividends from net investment income payable to holders of its shares.

The characterization of distributions to shareholders for financial reporting purposes is determined in accordance with federal income tax rules. Therefore, the source of a Fund’s distributions may be shown in the accompanying financial statements as either from, or in excess of, net investment income, net realized gain on investment transactions, or return of capital, depending on the type of book/tax differences that may exist. Capital accounts within the financial statements are adjusted for permanent book/tax differences. Reclassifications result primarily from the differences in tax treatment of net operating losses, passive foreign investment companies, and foreign currency transactions. The reclassifications are done annually at fiscal year-end and have no impact on the net asset values of the Funds and are designed to present each Fund’s capital accounts on a tax basis.

(f) Federal Income Taxes:It is each Fund’s policy to comply with the requirements of the Internal Revenue Code Subchapter M applicable to regulated investment companies and to distribute all of its taxable income to its shareholders. Provided the Funds maintain such compliance, no federal income tax provision is required. Each Fund is treated as a separate entity for the purpose of determining such compliance.

Financial Accounting Standards Board Accounting Standards Codification 740 – Income Taxes (“ASC 740”) requires the Funds to measure and recognize in their financial statements the benefit of a tax position taken (or expected to be taken) on an income tax return if such position will more likely than not be sustained upon examination based on the technical merits of the position. No tax years are currently under investigation. The Funds file income tax returns in the U.S., as well as New York State and New York City. The statute of limitations on the Funds’ tax returns remains open for the tax years 2016-2019. Management does not believe there are any uncertain tax positions that require recognition of a tax liability.

(g) Allocation Methods:The Trust accounts separately for the assets, liabilities and operations of each Fund. Expenses directly attributable to each Fund are charged to that Fund’s operations; expenses which are applicable to all Funds are allocated among them based on net assets. Income, realized and unrealized gains and losses, and expenses of each Fund are allocated among the Fund’s classes based on relative net assets, with the exception of distribution fees, transfer agency fees, and shareholder servicing and related fees.

(h) Estimates:These financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, which require using estimates and assumptions that affect the reported amounts therein. These unaudited interim financial statements reflect all adjustments which are, in the opinion of management, necessary to present a fair statement of results for the interim period. Actual results may differ from those estimates. All such estimates are of a normal recurring nature.

(i) Recent Accounting Pronouncements:In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2018-13 “Disclosure Framework -Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”) which modifies disclosure requirements for fair value measurements, principally for Level 3 securities and transfers between levels of the fair value hierarchy. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years. This standard was adopted by the Fund, resulting in new disclosures for the total gain or loss attributable to fair value changes in level 3 securities, and the elimination of the disclosure of the reasons for and amounts of transfers between Level 1 and Level 2, and the Fund’s valuation processes.

NOTE 3 — Investment Advisory Fees and Other Transactions with Affiliates:

(a) Investment Advisory Fees:Fees incurred by each Fund, pursuant to the provisions of the Trust’s Investment Advisory Agreement with Fred Alger Management, LLC (“Alger Management” or the “Investment Manager”), are payable monthly and computed based on the following rates.

Transactions in foreign securities may involve certain considerations and risks not typically associated with those of U.S. companies because of, among other factors, the level of governmental supervision and regulation of foreign security markets, and the possibility of political or economic instability. Additional risks associated with investing in emerging markets include increased volatility, limited liquidity, and less stringent regulatory and legal systems.

NOTE 5 — Borrowing:

The Funds may borrow from the Custodian on an uncommitted basis. Each Fund pays the Custodian a market rate of interest, generally based upon a rate of return with respect to each respective currency borrowed taking into consideration relevant overnight and short-term reference rates, the range of distribution between and among the interest rates paid on deposits to other institutions, less applicable commissions, if any. The Funds may also borrow from other in the Alger Fund Complex, as discussed in Note 3(i). For the six months ended April 30, 2020, the Funds had the following borrowings:

The significant unobservable inputs used in the fair value measurement of the Fund’s securities are revenue and EBITDA multiples, discount rates, and the probabilities of success of certain outcomes. Significant increases and decreases in these inputs in isolation and interrelationships between those inputs could result in significantly higher or lower fair value measurements than those noted in the table above. Generally, increases in revenue and EBITDA multiples, decreases in discount rates, and increases in the probabilities of success result in higher fair value measurements, whereas decreases in revenues and EBITDA multiples, increases in discount rates, and decreases in the probabilities of success result in lower fair value measurements.

Certain of the Funds’ assets and liabilities are held at carrying amount or face value, which approximates fair value for financial statements purposes. As of April 30, 2020, such assets were categorized within the ASC 820 disclosure hierarchy as follows:

NOTE 9 — Derivatives:

Financial Accounting Standards Board Accounting Standards Codification 815 – Derivatives and Hedging (“ASC 815”) requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements.

Options — Certain Funds seek to capture the majority of the returns associated with equity market investments. To meet this investment goal, these Funds invest in a broadly diversified portfolio of common stocks, while also buying and selling call and put options on equities and equity indexes. The Funds purchase call options to increase their exposure to the stock market and also provide diversification of risk. The Funds purchase put options in order to protect from significant market declines that may occur over a short period of time. The Funds will write covered call and cash secured put options to generate cash flows while reducing the volatility of the Funds’ portfolios. The cash flows may be an important source of the Funds’ returns, although written call options may reduce the Funds’ ability to profit from increases in the value of the underlying security or equity portfolio. The value of a call option generally increases as the price of the underlying stock increases and decreases as the stock decreases in price. Conversely, the value of a put option generally increases as the price of the underlying stock decreases and decreases as the stock increases in price. The combination of the diversified stock portfolio and the purchase and sale of options is intended to provide the Funds with the majority of the returns associated with equity market investments but with reduced volatility and returns that are augmented with the cash flows from the sale of options. During the six months ended April 30, 2020, options were used in accordance with these objectives.

The Funds’ option contracts were not subject to any rights of offset with any counterparty. All of the Funds’ options were exchange traded which utilize a clearinghouse that acts as an intermediary between buyer and seller, receiving initial and maintenance margin from both, and guaranteeing performance of the option contract.

There was no effect of derivative instruments on the accompanying Statements of Operations for the six months ended April 30, 2020.

There were no open derivative instruments as of April 30, 2020.

NOTE 10 — Principal Risks:

Alger Capital Appreciation Institutional Fund

Investing in the stock market involves risks, including the potential loss of principal. 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 war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, or other events could have a significant impact on the Fund and its investments. Growth stocks tend to be more volatile than other stocks as their prices tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political, and economic developments. A significant portion of assets will be invested in technology companies, which may be significantly affected by competition, innovation, regulation, and product obsolescence, and may be more volatile than the securities of other companies. Investments in the Consumer Discretionary Sector may be affected by domestic and international economies, consumer’s disposable income, consumer preferences and social trends. Foreign securities involve special risks including currency risk and risks related to political, social, or economic conditions.

Investments in the Consumer Discretionary Sector may be affected by domestic and international economies, consumer’s disposable income, consumer preferences and social trends. Foreign securities involve special risks including currency risk and risks related to political, social, or economic conditions. Assets may be focused in a small number of holdings, making them susceptible to risks associated with a single economic, political or regulatory event than a more diversified portfolio. Active trading may increase transaction costs, brokerage commissions, and taxes, which can lower the return on investment.

A significant portion of assets will be invested in technology and healthcare companies, which may be significantly affected by competition, innovation, regulation, and product obsolescence, and may be more volatile than the securities of other companies. Investing in companies of medium capitalizations involve the risk that such issuers may have limited product lines or financial resources, lack management depth, or have limited liquidity. Foreign securities involve special risks including currency risk and risks related to political, social, or economic conditions. Active trading may increase transaction costs, brokerage commissions, and taxes, which can lower the return on investment.

Alger Small Cap Growth Institutional Fund

Investing in the stock market involves certain risks, including the potential loss of principal. 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 war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, or other events could have a significant impact on the Fund and its investments. Growth stocks tend to be more volatile than other stocks as their prices tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political, and economic developments. A significant portion of assets will be invested in technology and healthcare companies, which may be significantly affected by competition, innovation, regulation, and product obsolescence, and may be more volatile than the securities of other companies. Investing in companies of small capitalizations involve the risk that such issuers may have limited product lines or financial resources, lack management depth, or have limited liquidity. Foreign and Emerging Market securities involve special risks including currency risk and risks related to political, social, or economic conditions.

ADDITIONAL INFORMATION (Unaudited)

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: transaction costs, if applicable, including sales charges (loads) and redemption fees; and ongoing costs, including management fees, distribution (12b-1) fees, if applicable, and other fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example below is based on an investment of $1,000 invested at the beginning of the six-month period starting November 1, 2019 and ending April 30, 2020.

Actual Expenses

The first line for each class of shares in the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you would have paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During the Six Months Ended April 30, 2020” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line for each class of shares in the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratios for each class of shares and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) and redemption fees. Therefore, the second line under each class of shares in the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Proxy Voting Policies

A description of the policies and procedures the Funds use to determine how to vote proxies relating to portfolio securities and the proxy voting record is available, without charge, by calling (800) 992-3863 or online on the Funds’ website at http://www.alger.com or on the SEC’s website at http://www.sec.gov.

Fund Holdings

The Board of Trustees 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 Investment 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 complete schedules of portfolio 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 reports on Form N-PORT. Previously, the Funds made their complete schedules of portfolio holdings available after the first and third fiscal quarters in regulatory filings on Form N-Q. The Funds’ Forms N-CSR, N-PORT and N-Q are available online on the SEC’s website at www.sec.gov.

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. From time to time, the Funds will communicate with these third parties to confirm that they understand the Funds’ policies and procedures regarding such disclosure. This agreement must be approved by the Trust’s Chief Compliance Officer.

The Board of Trustees 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.

ADDITIONAL INFORMATION (Unaudited) (Continued)

In addition to material the Funds routinely provide to shareholders, the Investment Manager may 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 versus an index (such as P/E ratio, alpha, beta, capture ratio, maximum drawdown, standard deviation, EPS forecasts, Sharpe ratio, information ratio, R-squared and market cap analysis), security specific impact on overall portfolio performance, 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.

Liquidity Risk Management Program

In accordance with Rule 22e-4 under the Investment Company Act of 1940, as amended, the Trust established a liquidity risk management program (the “LRMP”) in December 2018 and the Board, including a majority of the Independent Trustees, appointed the Investment Manager as the administrator of the LRMP. The Board, including a majority of the Independent Trustees, formally approved the LRMP in May of 2019. The Investment Manager administers the LRMP through a Liquidity Risk Committee (the “Committee”) that is chaired by the Investment Manager’s Chief Compliance Officer, who also serves as the Trust’s Chief Compliance Officer. The Board also approved an agreement with Intercontinental Exchange (“ICE”), a third-party vendor that assists the Funds with liquidity classifications required by Rule 22e-4. The Committee is responsible for assessing the liquidity risk of the Funds, subject to the oversight of the Investment Manager. The Committee reviews daily investment classification reports, continuously monitors the Funds’ liquidity risk, and meets at least quarterly.

The Board met to review the LRMP pursuant to Rule 22e-4 and at such meeting the Trust’s Chief Compliance Officer, on behalf of the Investment Manager as the administrator of the LRMP, provided the Board with a report that addressed the operation of the LRMP and assessed its adequacy and effectiveness of implementation and any material changes to the LRMP (the “Report”). The Report covered the period from December 1, 2018 through November 30, 2019 (the “Review Period”).

The Report stated that the Committee assessed each Fund’s liquidity risk by considering qualitative factors such as the Fund’s investment strategy, holdings, diversification of investments, redemption policies, cash flows, cash levels, shareholder concentration, and access to borrowings, among others, in conjunction with the quantitative classifications generated by ICE. In addition, in connection with the review of the Funds’ liquidity risks and the operation of the LRMP and the adequacy and effectiveness of its implementation, the Committee also evaluated the levels at which to set the reasonably anticipated trade size and market price impact. The Report described the process for determining that each Fund primarily holds investments that are highly liquid.
