Dear Shareholders, April 30, 2006 In the six months ended April 30, 2006, the U.S. economy remained strong, with inflation contained and overall Gross Domestic Product ("GDP") growth increasing at an annual rate of 4.8% as of March 31, 2006, three percentage points over the previous quarter's rate. And it wasn't simply that the economy overall was solid. During this period, corporate profits exceeded expectations; productivity stayed high; and growth companies in particular saw healthy stock appreciation. At the same time, the continued strength of the economy led to uncertainty about interest rates and inflation, and that in turn, kept the markets from breaking out of their trading range. At the Federal Open Market Committee (FOMC) meeting on March 28th, the Fed once again raised the key interest rate from 4.50% to 4.75%-the 15th consecutive increase since June 2004. The Fed noted that the current business climate is showing remarkable growth "but appears likely to moderate to a more sustainable pace."1 After new Fed Chairman Ben Bernanke appeared before the U.S. Congress on April 27th, it was widely believed that the Fed would stop raising rates before the summer. Subsequent economic data clouded the picture yet again, and the markets retreated. Nonetheless, rates remain low relative to historical levels, and while the precise number of future increases is uncertain, it is our belief that we are close to the peak of the current cycle. Rising interest rates have been a headwind for the markets, but the uncertainty over when the increases will stop has been even more of an impediment. Even with that uncertainty hovering over the market, solid GDP growth and robust corporate profit growth propelled equities higher during the six months that ended on April 30th, and nearly every market sector posted positive returns. And because corporate profits have increased at a faster rate than the major indices, the market overall has continued to become less expensive. For the six months ending April 30, 2006, the major indices ended up, with the Dow Jones Industrials up 10.21%, the Standard & Poor's 500 Index up 15.27% and the NASDAQ up 9.55%. Globally, foreign markets and emerging economies have been torrid. Asian stock markets offered substantial gains in 2005, and by the end of December, China had revised its official GDP figures upward by about $300 billion, more accurately reflecting the size and scope of its economy and the growing power of its consumers. Even those investors not directly exposed to those markets tended to benefit. Many companies have global exposure, and their earnings growth reflects the strong global economy. In the bond market, we saw a dramatic re-steepening of the yield curve for the six months ending April 30, 2006, with yields on the 2-year bond up 34 basis points to 4.86% and rates on the 10-year rising more than 50 basis points to 5.05%. The dramatic move upward in interest rates corresponded to renewed fears of inflation spurred on by rising energy and commodity prices as well as two more potential increases in the overnight target lending rate by the Fed. The 10-year Treasury note ------------------ (1) As of this writing, the key interest rate experienced another quarter percentage point hike on May 10, 2006 to 5.0%. -2- pierced 5.00% for the first time in nearly four years on the heels of a continued robust economic landscape, ever-increasing capacity utilization and tight labor markets. Despite the continued rise in interest rates, we believe that the overall low rates by historical standards and record levels of household net worth have buoyed consumer spending, with U.S. consumers now sustaining higher levels of debt than they have in years. In fact, in 2005 U.S. consumers defied expectations by absorbing rising energy prices without substantial decreases in spending. The first months of 2006 saw no significant change in these trends, as both growth and productivity outpaced expectations. Going forward, we believe that both the U.S. and the global economy will continue to expand, and our outlook for corporate earnings for 2006 is positive. U.S. markets may remain range-bound so long as the interest rate picture stays uncertain, but by most measures, the markets are trading at reasonable valuations backed by strong fundamentals. We want you to know that we value the trust you have placed in Alger. We will continue to look for dynamic, forward-looking companies that are creating the business and marketplaces of tomorrow, bringing growth opportunities to our investors.

THE ALGER INSTITUTIONAL FUNDS -50- NOTES TO FINANCIAL STATEMENTS (UNAUDITED) NOTE 1--GENERAL: The Alger Institutional Funds (formerly The Alger Institutional Fund) (the "Trust"), is a diversified, open-end registered investment company organized as a business trust under the laws of the Commonwealth of Massachusetts. The Trust operates as a series company and currently issues an unlimited number of shares of beneficial interest in eight funds--LargeCap Growth Fund, SmallCap Growth Fund, MidCap Growth Fund, Capital Appreciation Fund, Balanced Fund, Socially Responsible Growth Fund, Technology Fund and Core Fixed-Income Fund (collectively, the "Funds" or individually, each a "Fund"). The LargeCap Growth Fund, SmallCap Growth Fund, MidCap Growth Fund, Capital Appreciation Fund, Socially Responsible Growth Fund and Technology Fund normally invest primarily in equity securities and each has an investment objective of long-term capital appreciation. The Balanced Fund's investment objectives are current income and long-term capital appreciation which it seeks to achieve through investing in equity and fixed-income securities. The Core Fixed-Income Fund's investment objective is current income consistent with the preservation of capital value, which it seeks by investing in fixed-income securities. Each Fund offers Class I and Class R shares. Class R shares were first offered January 27, 2003. Each class has identical rights to assets and earnings except that only Class R shares have a plan of distribution and bear the related expenses. NOTE 2--SIGNIFICANT ACCOUNTING POLICIES: (a) INVESTMENT VALUATION: Investments of the Funds are valued on each day the New York Stock Exchange (the "NYSE") is open as of the close of the NYSE (currently 4:00 p.m. Eastern time). Listed securities for which such information is readily available are valued at the last reported sales price or, in the absence of reported sales, at the mean between the bid and asked price or, 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. Securities listed on foreign exchanges are valued at the last reported sales price or, in the absence of reported sales, at the mean between the bid and asked price. Securities included within the Nasdaq market shall be valued at the Nasdaq official closing price (NOCP) on the day of valuation, or if there be no NOCP issued, at the last sale price on such day. Securities included within the Nasdaq market for which there is no NOCP and no last sale price on the day of valuation shall be valued at the mean between the last bid and asked prices on such day. 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 of Trustees. Securities in which the Funds invest may be traded in markets that close before the close of the NYSE. Normally, developments that occur between the close of the foreign markets and the close of the NYSE(normally 4:00 p.m. THE ALGER INSTITUTIONAL FUNDS -51- NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED) Eastern time) will not be reflected in the Fund's net asset value. However, if it be determined that such developments are so significant that they will materially affect the values of the Funds' securities, the Funds may adjust the previous closing prices to reflect what the investment manager, under the direction of the Board of Trustees, believes to be the 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. Short-term securities having a remaining maturity of sixty days or less are valued at amortized cost which approximates market value. Shares of mutual funds are valued at the net asset value of the underlying mutual fund. (b) 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. (c) FOREIGN CURRENCY TRANSLATIONS: 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. 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 Statements of Operations. (d) REPURCHASE AGREEMENTS: The Funds enter into repurchase agreements with approved institutions. The repurchase agreements are collateralized by U.S. Government securities, which are either received and held in physical possession by the custodian or received by such custodian in book-entry form through the Federal Reserve book-entry system. The collateral is valued on a daily basis during the term of the agreement to ensure that its value equals or exceeds the agreed-upon repurchase price to be repaid to the Funds. Additional collateral is obtained when necessary. (e) LENDING OF FUND SECURITIES: The Funds may lend their securities to financial institutions, provided that the market value of the securities loaned will not at any time exceed one third of a Fund's total assets, as defined. The Funds THE ALGER INSTITUTIONAL FUNDS -52- NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED) earn fees on the securities loaned. In order to protect against the risk of failure by the borrower to return the securities loaned or any delay in the delivery of such securities, the loan is collateralized by cash, letters of credit or U.S. Government securities that are maintained in an amount equal to at least 100 percent of the current market value of the loaned securities. The market value of the loaned securities is determined at the close of business of the Funds and any required additional collateral is delivered to the Funds on the next business day. As of April 30, 2006, there were no securities on loan. (f) DIVIDENDS TO SHAREHOLDERS: Dividends payable to shareholders are recorded on the ex-dividend date. With respect to all Funds, dividends from net investment income and distributions from net realized gains, offset by any loss carry forward, 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 of 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 the Funds' 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 and amortization adjustments on debt securities. The reclassifications had no impact on the net asset values of the Funds and are designed to present the Funds' capital accounts on a tax basis. (g) FEDERAL INCOME TAXES: It is each Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its investment company taxable income to its shareholders. Provided a Fund maintains such compliance, no federal income tax provision is required. Each Fund is treated as a separate entity for the purpose of determining such compliance. (h) 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, which are only applicable to Class R shares. (i) INDEMNIFICATION: The Trust enters into contracts that contain a variety of indemnification provisions. The Trust's maximum exposure under these arrangements is unknown. The Trust does not anticipate recognizing any loss related to these arrangements. THE ALGER INSTITUTIONAL FUNDS -53- NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED) (j) OTHER: These financial statements have been prepared in accordance with U.S. generally accepted accounting principles, which require using estimates and assumptions that affect the reported amounts therein. Actual results may differ from those estimates. NOTE 3--INVESTMENT MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES: (a) INVESTMENT MANAGEMENT FEES: Fees incurred by each Fund, pursuant to the provisions of its Investment Management Agreement with Fred Alger Management, Inc.

(b) DISTRIBUTION FEES: Class R shares: The Funds have adopted a Distribution Plan pursuant to which Class R shares of each Fund pays Fred Alger & Company, Incorporated, the Trust's distributor (the "Distributor") and an affiliate of Alger Management, a fee at the annual rate of .50% of the respective average daily net assets of the Class R shares of the designated Funds to compensate the Distributor for its activities and expenses incurred in distributing the Class R shares.

THE ALGER INSTITUTIONAL FUNDS -61- NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED) On December 16, 2005, Alger Management received from the staff of the SEC a "Wells Notice" which indicated that the staff intends to recommend that the Commission bring civil enforcement action for possible violations of the federal securities laws. "Wells Notices" also have been sent to certain companies affiliated with Alger Management, as well as certain present and former members of its senior management. The Wells Notices arose out of the SEC's staff ongoing investigation of market timing and late trading practices in the mutual fund industry. Alger Management and the other recipients have the opportunity to respond to the staff before the staff makes a formal recommendation. Alger Management submitted a response in January 2006. On June 7, 2006, Alger Management, its parent, Alger Inc., and their affiliated companies reached an agreement in principle with the staff of the New York Regional Office of the SEC and with the staff of the New York State Attorney General's office ("NYAG") resolving all issues with the SEC and the NYAG related to the allegations of mutual fund market timing and late trading that were the subject of the December 2005 Wells Notice. Alger Management and Alger Inc. are working with the staff of the SEC and the NYAG to finalize the agreement. The agreement is subject to the approval of the SEC and the NYAG. In the proposed settlement agreement, without admitting or denying liability, the firm will consent to the payment of $30 million dollars to reimburse fund shareholders; a fine of $10 million; and certain other remedial measures including a reduction in management fees of $1 million per year for five years. The entire $40 million and fee reduction will be available for the benefit of investors. Alger Management has advised the Fund that the proposed settlement payment is not expected to adversely affect the operations of the Manager, Alger Inc. or their affilates, or adversely affect their ability to continue to provide services to the Fund. On August 31, 2005, the West Virginia Securities Commissioner in an ex parte Summary Order to Cease and Desist and Notice of Right to Hearing concluded that Alger Management and Alger Inc. had violated the West Virginia Uniform Securities Act, and ordered Alger Management and Alger Inc. to cease and desist from further violations of the Act by engaging in the market-timing related conduct described in the order. The ex parte order provided notice of their right to a hearing with respect to the violations of law asserted by the Commissioner. Other firms unaffiliated with Alger Management were served with similar orders. Alger Management and Alger Inc. intend to request a hearing for the purpose of seeking to vacate or modify the order. In addition, in 2003 and 2004 several purported class actions and shareholder derivative suits were filed against various parties in the mutual fund industry, including Alger Management, certain mutual funds managed by Alger Management (the "Alger Mutual Funds"), and certain current and former Alger Mutual Fund trustees and officers, alleging wrongful conduct related to market-timing and late-trading by mutual fund shareholders. These cases were THE ALGER INSTITUTIONAL FUNDS -62- NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED) transferred to the U.S. District Court of Maryland by the Judicial Panel on Multidistrict Litigation for consolidated pre-trial proceedings. In September 2004, consolidated amended complaints involving these cases -- a Consolidated Amended Fund Derivative Complaint (the "Derivative Complaint") and two substantially identical Consolidated Amended Class Action Complaints (together, the "Class Action Complaint") -- were filed in the Maryland federal district court under the caption number 1:04-MD-15863 (JFM). In April 2005, a civil lawsuit involving similar allegations was filed by the West Virginia Attorney General and also transferred to the Maryland District Court. The Derivative Complaint alleged (i) violations, by Alger Management and, depending on the specific offense alleged, by its immediate parent, Alger Inc., which is the Distributor of the Alger Mutual Funds, and/or the fund trustee defendants, of Sections 36(a), 36(b), 47, and 48 of the Investment Company Act of 1940 (the "Investment Company Act") and of Sections 206 and 215 of the Investment Advisers Act of 1940, breach of fiduciary duty, and breach of contract, (ii) various offenses by other third-party defendants, and (iii) unjust enrichment by all the named defendants. The Class Action Complaint alleged, in addition to the offenses listed above, (i) violations, by Alger Management, Alger Inc., their affiliates, the funds named as defendants, and the current and former fund trustees and officers, of Sections 11, 12(a)(2), and 15 of the Securities Act of 1933, Sections 10(b) (and Rule 10b-5 thereunder) and 20(a) of the Securities Exchange Act of 1934 (the "1934 Act"), and Section 34(b) of the Investment Company Act of 1940, (ii) breach of contract by the funds named as defendants, and (iii) unjust enrichment of the defendants. The West Virginia attorney general action also alleges violations of the West Virginia Consumer Credit and Protection Act and other wrongful conduct. Motions to dismiss the Class Action Complaint and the Derivative Complaint were subsequently filed. On November 3, 2005, the district court issued letter rulings dismissing both complaints in their entirety with respect to the Alger Mutual Funds and dismissing all claims against the other Alger defendants, other than the claims under the 1934 Act and Section 36(b) of the Investment Company Act (as to which the court deferred ruling with respect to the Alger Mutual Fund Trustees), with leave to the class action plaintiffs to file amended complaints against those defendants with respect to claims under state law.Orders implementing the letter rulings are being entered. On January 11, 2006, the Alger defendants filed a motion for partial reconsideration of the district court's ruling with respect to the Section 10(b), Rule 10b-5 and Section 36(b) claims against them; the district court denied the motion on February 9, 2006. Alger Management does not believe that the Alger Mutual Funds are themselves targets of the regulatory investigations as potential enforcement defendants. THE ALGER INSTITUTIONAL FUNDS -63- NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED) The SEC and, in some cases, state government authorities have a variety of administrative and civil enforcement powers, including injunctive powers, authority to assess fines and penalties and order restitution, authority to limit the activities of a person or company and other enforcement powers, that may be exercised administratively or through the courts. Under Section 9(a) of the Investment Company Act, if any of the various regulatory proceedings or lawsuits were to result in a court injunction against Alger Management or Alger Inc., Alger Management would, in the absence of exemptive relief granted by the SEC, be barred from serving as investment adviser/sub-adviser for any registered investment company, including the Fund. While exemptive relief from Section 9(a) has been granted in certain other cases, there is no assurance that such exemptive relief would be granted if sought. In addition, it is possible that these matters and/or other developments resulting from these matters could result in loss of Alger Management personnel, diversion of time and attention of Alger Management personnel, diminishment of financial resources of Alger Management, or other consequences potentially adverse to the Fund. Alger Management cannot predict the potential effect of such actions upon Alger Management or the Fund. There can be no assurance that the effect, if any, would not be material. THE ALGER INSTITUTIONAL FUNDS -64- ADDITIONAL INFORMATION (UNAUDITED) SHAREHOLDER EXPENSE EXAMPLE (UNAUDITED) As a shareholder of the Fund, you incur two types of costs: transaction costs, if applicable, 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, 2005 and ending April 30, 2006. 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 Period" 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. 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. SHAREHOLDER EXPENSE EXAMPLE (UNAUDITED) (CONTINUED) -65-
